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

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

118 (hinst): Remove unneeded extern declaration.
119 (_start): Remove initialization of above variables; remove
120 initialization of hinst, as cache_system_info now does that.

152 Support for filesystem notifications on MS-Windows.
153 * w32proc.c (sys_select): If drain_message_queue returns non-zero,
154 and this is a TTY frame, signal the caller that keyboard input is

264 * w32.c (unsetenv): Return 0 if the input string is too long.
266 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>

283 no longer needed here.
284 (set_time_zone_rule_tz1, set_time_zone_rule_tz2) [LOCALTIME_CACHE]:
285 Move to inside set_time_zone_rule; they don't need file scope any more.
286 (set_time_zone_rule): Maintain the TZ=value string separately.
287 (syms_of_editfns): Don't initialize initial_tz;
288 init_editfns now does it.
289 * emacs.c (dump_tz) [HAVE_TZSET]: Now const.
290 * lisp.h (xputenv): New decl.
292 2012-12-08 Fabrice Popineau <fabrice.popineau@gmail.com>

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

317 (record_child_status_change, handle_child_signal, deliver_child_signal)

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

325 (emacs_sigaction_init): Assume SIGCHLD is defined.
326 (init_signals): Assume SIGALRM, SIGCHLD, SIGHUP, SIGKILL,

336 This will cause a production Emacs to dump core instead of
339 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
341 * frame.c (make_frame): Do not set window's buffer to t.
342 * window.c (Fsplit_window_internal): Likewise. Previously it was
343 used to indicate that the window is being set up. Now we use
344 set_window_buffer for all new windows, so the condition in ...
345 (Fset_window_buffer): ... is always true and can be removed.
347 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
349 Convenient macro to check whether the buffer is hidden.
350 * buffer.h (BUFFER_HIDDEN_P): New macro.

357 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG
358 if the child process is still running. Instead, exit the wait
359 loop and return zero. (Bug#13086)

376 Fix a recently-introduced delete-process race condition.
377 * callproc.c, process.h (record_kill_process):
378 New function, containing part of the old call_process_kill.
379 (call_process_kill): Use it.
380 This does not change call_process_kill's behavior.
381 * process.c (Fdelete_process): Use record_kill_process to fix a
382 race condition that could cause Emacs to lose track of a child.
384 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
386 Avoid code duplication between prev_frame and next_frame.
387 * frame.c (candidate_frame): New function. Add comment.
388 (prev_frame, next_frame): Use it. Adjust comment.
390 2012-12-06 Eli Zaretskii <eliz@gnu.org>
392 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
393 fails, signal an error instead of continuing with an empty
395 Encode expanded temp file pattern before passing it to mkstemp or
398 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
399 Encode the file name before passing it to dostounix_filename, in
400 case it will downcase it (under w32-downcase-file-names).
403 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
405 Minor call-process cleanups.
406 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
407 at the same time as other platforms, to simplify analysis.
408 No need for fd0_volatile since we have synch_process_fd.
409 Avoid needless emacs_close; arg is always negative.
411 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
413 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
416 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
418 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
419 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
420 and mouse_face_hidden members to a bitfields.
421 * frame.h (struct frame): Remove set-but-not-used space_width member.
422 (FRAME_SPACE_WIDTH): Remove.

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

513 (safe_alloca_unwind): Use it.
514 * lisp.h (free_save_value): New prototype.
515 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.

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

565 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
566 display for sliced images (Bug#10500).
568 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
570 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
572 * doc.c (Fdocumentation): Re-add handling of function-documentation,
573 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).

590 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
592 * callproc.c (Fcall_process): Fix vfork portability problems.
593 Do not assume that fd[0], count, filefd, and save_environ survive
594 vfork. Fix bug whereby wrong errno value could be reported for
595 pipe failure. Some minor cleanups, too, as follows. Move buf and
596 bufsize to the context where they're needed. Change new_argv to
597 be of type char **, as this is more convenient and avoids casts.
598 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
599 Now local constants, not macros.
601 2012-11-18 Kenichi Handa <handa@gnu.org>
603 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
604 for the variable "f".

651 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
652 between bpos_covered and bpos_max. This fixes cursor display when
653 several display strings follow each other.
655 * .gdbinit (pgx): If the glyph's object is a string, display the
656 pointer to string data, rather than the value of the string object
657 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
659 * indent.c (Fvertical_motion): If the starting position is covered
660 by a display string, return to one position before that, to avoid
661 overshooting it inside move_it_to. (Bug#12930)
663 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
665 * frame.h (struct frame): Remove display_preempted member

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

682 of a literal "/". (Bug#12955)
683 (gl-stamp): Invoke fc.exe directly, not through cmd.
685 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>

688 * dired.c: Assume HAVE_DIRENT_H.
689 (NAMLEN): Remove, replacing with ...
690 (dirent_namelen): New function. All uses changed. Use the GNU macro
691 _D_EXACT_NAMELEN if available, as it's faster than strlen.
692 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
693 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
694 * makefile.w32-in (DIR_H): Remove. All uses replaced with

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

724 simplify large 'if' statements.
725 (redisplay_internal): Generalize commonly used
726 'tail' and 'frame' local variables.
728 2012-11-22 Eli Zaretskii <eliz@gnu.org>
730 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
731 with Windows system header.
733 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
735 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
736 * alloc.c: Assume unistd.h exists.
737 * fileio.c (Fexpand_file_name) [DOS_NT]: Use getcwd, not getwd.
738 * sysdep.c (get_current_dir_name): Assume getcwd exists.
739 (getwd) [USG]: Remove; no longer needed.

752 * emacs.c (main): Set the G_SLICE environment variable for all
753 Cygwin builds, not just GTK builds. See
754 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
756 2012-11-21 Eli Zaretskii <eliz@gnu.org>
758 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
759 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
760 Define for the MSVC compiler.
762 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
764 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
765 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
766 dostounix_filename. Prevents crashes down the road, because
767 dostounix_filename assumes it gets a unibyte string. Reported by
768 Michel de Ruiter <michel@sentient.nl>, see
769 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html
771 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>

796 (redisplay_internal): Likewise. Fix indentation.
798 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
800 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
801 (syms_of_eval): Remove corresponding defsubr.
802 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
804 2012-11-19 Daniel Colascione <dancol@dancol.org>
806 * w32fns.c (Fx_file_dialog):
807 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
808 cygwin_convert_file_name*.

811 Rename cygwin_convert_path* to cygwin_convert_file_name*.
813 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
815 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
817 2012-11-18 Eli Zaretskii <eliz@gnu.org>
819 * w32select.c: Include w32common.h before w32term.h, so that
820 windows.h gets included before w32term.h uses some of its
823 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
825 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
827 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
829 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
831 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).

836 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
837 Needed following 2012-10-20 change. (Bug#12902)
839 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
841 * w32proc.c (waitpid): Remove unused label get_result.
843 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
845 * makefile.w32-in (SYSWAIT_H): New macro.
846 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
847 ($(BLD)/sysdep.$(O)): Update dependencies.
849 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
851 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
852 * callproc.c (relocate_fd): Assume F_DUPFD.
853 * emacs.c, term.c (O_RDWR): Remove.
854 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
855 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
856 * nsterm.m: Assume <fcntl.h> exists.
857 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
858 (create_pty, Fmake_network_process, server_accept_connection)
859 (wait_reading_process_output, init_process_emacs):
861 (wait_reading_process_output): Put in a special case for WINDOWSNT
862 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
863 It's not clear this is needed, but it's a more-conservative change.
864 (create_process): Assume FD_CLOEXEC.
865 (create_process, create_pty): Assume O_NOCTTY.
866 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
867 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
868 Omit if not DOS_NT, since F_GETFL is not defined there.

870 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
872 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
873 lack it, since gnulib guarantees this.
874 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
876 2012-11-17 Eli Zaretskii <eliz@gnu.org>
878 * w32.c (faccessat): Pretend that directories have the execute bit
879 set. Emacs expects that, e.g., in files.el:cd-absolute.
881 * w32proc.c (create_child): Don't clip the PID of the child
882 process to fit into an Emacs integer, as this is no longer a
884 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
885 reaping only the process specified by PID argument, if that is
886 positive. Use PID instead of dead_child to know which process to
887 reap. Wait for the child to die only if WNOHANG is not in
889 (sys_select): Don't set dead_child.
891 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
892 as it is no longer needed.
894 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
896 (record_child_status_change): Remove the setting of
897 record_at_most_one_child for the !WNOHANG case.
899 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
901 Fix problems in ns port found by static checking.
902 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
903 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
904 not to process group.
905 (ns_select): Use emacs_write, not write, as that's more robust
906 in the presence of signals.
907 (fd_handler:): Check for read errors.
909 2012-11-16 Glenn Morris <rgm@gnu.org>
911 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
913 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
915 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
917 2012-11-16 Eli Zaretskii <eliz@gnu.org>
919 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
920 use the same value of thread handle.
921 (start_timer_thread): If the timer thread exited (due to error),
922 clean up by closing the two handles it used. Duplicate the caller
923 thread's handle here, so it gets duplicated only once, when
924 launching the timer thread. Set priority of the timer thread, not
926 (getitimer): Don't duplicate the caller thread's handle here.
929 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
931 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
934 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
936 Remove no-longer-used pty_max_bytes variable.
937 * process.c (pty_max_bytes): Remove; unused.
938 (send_process): Do not set it.
940 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
942 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
945 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
947 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
948 This follows up on the 2012-09-29 patch that removed indirection
949 for the 'function' field. Reported by Sergey Vinokurov in
950 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
952 2012-11-14 Eli Zaretskii <eliz@gnu.org>
954 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
955 different name, as the MS runtime does not have such a function,
956 and probably never will.) All callers changed. Ignore DIRFD
957 value if PATH is an absolute file name, to match Posix spec
958 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
961 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
963 * xdisp.c (echo_area_display, redisplay_internal):
964 Omit redundant check whether frame_garbaged is set.
966 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
968 Use faccessat, not access, when checking file permissions (Bug#12632).
969 This fixes a bug that has been present in Emacs since its creation.
970 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
971 which must set some sort of record. (Torek's bug report was against
972 a predecessor of GNU Emacs, but GNU Emacs happened to have the
973 same common flaw.) See Torek's Usenet posting
974 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
975 Posted: Fri Apr 8 14:18:56 1983.

983 * process.c (allocate_pty):
985 Use effective UID when checking permissions, not real UID.
986 * callproc.c (init_callproc):
987 * charset.c (init_charset):
988 * lread.c (load_path_check, init_lread):
989 Test whether directories are accessible, not merely whether they exist.
990 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
991 * fileio.c (check_existing, check_executable, check_writable)
993 Use symbolic names instead of integers for the flags, as they're
995 (check_writable): New arg AMODE. All uses changed.
996 Set errno on failure.
997 (Ffile_readable_p): Use faccessat, not stat + open + close.
998 (Ffile_writable_p): No need to call check_existing + check_writable.
999 Just call check_writable and then look at errno. This saves a syscall.
1000 dir should never be nil; replace an unnecessary runtime check
1001 with an eassert. When checking the parent directory of a nonexistent
1002 file, check that the directory is searchable as well as writable, as
1003 we can't create files in unsearchable directories.
1004 (file_directory_p): New function, which uses 'stat' on most platforms
1005 but faccessat with D_OK (for efficiency) if WINDOWSNT.
1006 (Ffile_directory_p, Fset_file_times): Use it.
1007 (file_accessible_directory_p): New function, which uses a single
1008 syscall for efficiency.
1009 (Ffile_accessible_directory_p): Use it.
1010 * xrdb.c (file_p): Use file_directory_p.
1011 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
1012 * lread.c (openp): When opening a file, use fstat rather than
1013 stat, as that avoids a permissions race. When not opening a file,
1014 use file_directory_p rather than stat.
1015 (dir_warning): First arg is now a usage string, not a format.
1016 Use errno. All uses changed.
1017 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
1018 that merely introduced a race.
1019 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
1020 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
1021 and similarly for the other O_* flags.
1022 * w32.c (sys_faccessat): Rename from sys_access and switch to
1023 faccessat's API. All uses changed.
1024 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
1025 (magic_db): Rename from magic_file_p.
1026 (magic_db, search_magic_path): Return an XrmDatabase rather than a
1027 char *, so that we don't have to test for file existence
1028 separately from opening the file for reading. This removes a race
1029 fixes a permission-checking problem, and simplifies the code.
1031 (file_p): Remove; no longer needed.
1033 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
1035 Omit glyphs initialization at startup.

1041 * xdisp.c (clear_garbaged_frames): Likewise.
1043 2012-11-13 Eli Zaretskii <eliz@gnu.org>
1045 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
1046 passed to pint2str and pint2hrstr to be at most the size of the
1047 frame's decode_mode_spec_buffer. This avoids crashes with very
1048 large values of FIELD_WIDTH argument to decode_mode_spec.
1051 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
1053 Fix a race with verify-visited-file-modtime (Bug#12863).
1054 Since at least 1991 Emacs has ignored an mtime difference of no
1055 more than one second, but my guess is that this was to work around
1056 file system bugs that were fixed long ago. Since the race is
1057 causing problems now, let's remove that code.
1058 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
1059 whose time stamp is off by no more than a second. Insist that the
1060 file time stamps match exactly.
1062 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
1064 * frame.h (struct frame): Convert external_tool_bar member to
1065 1-bit unsigned bitfield.
1066 * termhooks.h (struct terminal): Remove mouse_moved member since
1067 all users are long dead. Adjust comment on mouse_position_hook.
1069 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
1071 Simplify by using FOR_EACH_FRAME here and there.
1072 * frame.c (next_frame, prev_frame, other_visible_frames)
1073 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
1074 * w32term.c (x_window_to_scroll_bar): Likewise.
1075 * window.c (window_list): Likewise.
1076 * xdisp.c (x_consider_frame_title): Likewise.
1077 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
1078 * xfns.c (x_window_to_frame, x_any_window_to_frame)
1079 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
1080 * xmenu.c (menubar_id_to_frame): Likewise.
1081 * xselect.c (frame_for_x_selection): Likewise.
1082 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
1083 (x_window_to_menu_bar): Likewise.
1084 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
1086 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
1088 * data.c (Qdefalias_fset_function): Now static.
1090 Another tweak to vectorlike_header change.
1091 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
1092 Remove, and replace all uses with ...
1093 (next_in_free_list, set_next_in_free_list):
1094 New functions, which respect C's aliasing rules better.
1096 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
1098 * window.c (list4i): Rename from 'quad'. All uses changed.
1099 Needed because <sys/types.h> defines 'quad' on Solaris 10.
1101 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
1103 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
1104 warning about mixing declarations and code in ISO C90.
1106 2012-11-10 Martin Rudalics <rudalics@gmx.at>
1108 * window.c (Fsplit_window_internal): Set combination limit of
1109 new parent window to t iff Vwindow_combination_limit is t;
1110 fixing a regression introduced with the change from 2012-09-22.
1111 (Fset_window_combination_limit): Fix doc-string.
1113 2012-11-10 Eli Zaretskii <eliz@gnu.org>
1115 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
1116 amount when the scroll margins are too large. When scrolling
1117 backwards in the buffer, give up if cannot reach point or the
1118 scroll margin within a reasonable number of screen lines.
1119 Fixes point position in window under scroll-up/down-aggressively when
1120 point is positioned many lines beyond the window top/bottom.
1123 * ralloc.c (relinquish): If real_morecore fails to return memory
1124 to the system, don't crash; instead, leave the last heap
1125 unchanged and return. (Bug#12774)
1127 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
1129 * lisp.h (AUTOLOADP): New macro.

1134 (Finteractive_form): Simplify.
1135 (Fquo): Don't insist on having at least 2 arguments.
1136 (Qdefalias_fset_function): New var.
1138 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
1140 * image.c (xpm_make_color_table_h): Change to hashtest_equal.

1146 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
1148 Fix recently introduced crash on MS-Windows (Bug#12839).
1149 * w32term.h (struct scroll_bar): Use convenient header.
1150 (SCROLL_BAR_VEC_SIZE): Remove.
1151 * w32term.c (x_scroll_bar_create): Use VECSIZE.
1153 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
1155 Tweak last vectorlike_header change.
1156 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
1157 vectorlike object on the free list. This is introduced to avoid
1158 some (but not all) pointer casting and aliasing problems, see
1159 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
1160 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike

1164 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
1166 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
1167 been removed, so remove them here also.
1169 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
1171 * doc.c (Fdocumentation): Handle new property
1172 dynamic-docstring-function to replace the old ad-advice-info.
1174 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
1176 * fns.c (Qeql, hashtest_eq): Now static.
1178 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
1180 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
1181 * fns.c (hashfn_eq, hashfn_eql, sxhash):
1182 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.

1189 * lisp.h (sxhash_combine): New inline function, with the contents
1190 of the old SXHASH_COMBINE.

1192 special hash function containing a comparison that always yields 1.
1194 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
1196 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
1197 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
1198 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
1201 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
1203 * image.c (xpm_make_color_table_h): Fix compiler error because
1204 make_hash_table changed.

1208 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
1210 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
1212 Use ad-hoc comparison function for the profiler's hash-tables.
1213 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
1214 (make_log): Use them.
1215 (handle_profiler_signal): Don't inhibit quit any longer since we don't
1216 call Fequal any more.

1264 (SETUP_ON_FREE_LIST): Adjust XSETPVECTYPESIZE usage.
1265 (Fmake_bool_vector): Likewise.
1266 (struct large_vector): New type to represent allocation unit for
1267 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
1268 (large_vectors): Change type to struct large_vector.
1269 (allocate_vector_from_block): Simplify.
1270 (PSEUDOVECTOR_NBYTES): Replace with...

1292 * keyboard.c (event_to_kboard): Do not dereference
1293 frame_or_window field of SELECTION_REQUEST_EVENT
1294 and SELECTION_CLEAR_EVENT events (Bug#12814).

1299 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
1300 such as Scroll Lock, if the respective keys are treated as
1301 function keys, not as modifiers. This avoids destroying non-ASCII
1302 keyboard input when Scroll Lock is toggled ON. (Bug#12806)

1306 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
1308 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
1310 Restore some duplicate definitions (Bug#12814).
1311 This undoes part of the 2012-11-03 changes. Some people build
1312 with plain -g rather than with -g3, and they need the duplicate
1313 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
1314 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):

1320 to keypad keys (Bug#12816).
1322 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
1324 Minor adjustments of recently-changed frame functions.
1325 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
1326 known to be a frame (we're in the FRAMEP branch).
1327 * lisp.h (Qframep): Remove decl. frame.h declares this.
1328 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
1329 since they're meant for Lisp fixnum values.
1331 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
1333 * window.c (Fwindow_combination_limit): Revert to the only
1334 required argument and adjust docstring as suggested in

1393 2012-11-05 Chong Yidong <cyd@gnu.org>
1395 * process.c (wait_reading_process_output): Revert previous change.
1397 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
1399 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).

1413 (tcgetpgrp, setpgid, setsid): New functions.
1414 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
1415 * term.c (no_controlling_tty): Remove; unused.
1416 * w32proc.c (setpgrp): Remove.
1417 (setsid, tcgetpgrp): New functions.
1419 Simplify by assuming __fpending.
1420 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
1421 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
1422 Do not assume that __fpending's result fits in int.
1424 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
1426 Remove EMACS_OUTQSIZE+sleep hack.
1427 * dispnew.c (update_frame_1): Remove hack for terminals slower
1428 than 2400 bps, which throttled Emacs by having it sleep.
1429 This code hasn't worked since at least 2007, when the multi-tty stuff
1430 was added, and anyway those old terminals are long dead.
1431 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
1432 without the dispnew.c change, as dispnew.c doesn't include systty.h.
1434 Fix data-loss with --version (Bug#9574).
1435 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
1436 as we can't assume that emacs_strerror is initialized, and strerror
1437 is good enough here.
1438 (main): Invoke atexit earlier, to catch earlier instances of
1439 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
1441 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
1443 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
1444 (keyDown): Remap keypad keys to X11 virtual key codes.
1446 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
1448 Fix data-loss with --batch (Bug#9574).
1449 * emacs.c: Include <close-stream.h>.
1450 (close_output_streams): New function.
1451 (main): Pass it to atexit, so that Emacs closes stdout and stderr
1452 and handles errors appropriately.
1453 (Fkill_emacs): Don't worry about flushing, as close_output_stream
1456 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
1457 The symptom is a diagnostic "GLib-WARNING **: In call to
1458 g_spawn_sync(), exit status of a child process was requested but
1459 SIGCHLD action was set to SIG_IGN and ECHILD was received by
1460 waitpid(), so exit status can't be returned." The diagnostic
1461 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
1462 The real bug is a race condition between Emacs and glib: Emacs
1463 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
1464 so that glib can't find it. Work around the bug by invoking
1465 waitpid only on subprocesses that Emacs itself creates.
1466 * process.c (create_process, record_child_status_change):
1467 Don't use special value -1 in pid field, as the caller now must
1468 know the pid rather than having the callee infer it.
1469 The inference was sometimes incorrect anyway, due to another race.
1470 (create_process): Set new 'alive' member if child is created.
1471 (process_status_retrieved): New function.
1472 (record_child_status_change): Use it.
1473 Accept negative 1st argument, which means to wait for the
1474 processes that Emacs already knows about. Move special-case code
1475 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
1476 processes that have already been waited for, by testing and
1477 clearing new 'alive' member.
1478 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
1479 now does this internally.
1480 (handle_child_signal): Let record_child_status_change do all
1481 the work, since we do not want to reap all exited child processes,
1482 only the child processes that Emacs itself created.
1483 * process.h (Lisp_Process): New boolean member 'alive'.
1485 Omit duplicate definitions no longer needed with gcc -g3.
1486 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
1487 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
1488 Define only as macros. There's no longer any need to also define
1489 these symbols as enums or as constants, since we now assume
1490 gcc -g3 when debugging.
1492 2012-11-03 Eli Zaretskii <eliz@gnu.org>
1494 * lisp.mk: Adjust comments to the fact that term/internal is now
1495 loaded from loadup.el.
1497 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
1498 (msdos_fatal_signal): New function.
1499 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
1502 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
1503 for GCC versions before 4.
1504 (emacs_raise): Define to call msdos_fatal_signal.
1506 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
1507 iterator when starting in the middle of a display or overlay
1510 2012-11-03 Chong Yidong <cyd@gnu.org>
1512 * process.c (wait_reading_process_output): Clean up the last
1515 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
1517 * process.c (wait_reading_process_output): Avoid a race condition
1518 with SIGIO delivery (Bug#11536).
1520 2012-11-03 Chong Yidong <cyd@gnu.org>
1522 * buffer.c (cursor_type): Untabify docstring.
1524 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
1526 * frame.h (struct frame): Drop can_have_scroll_bars member
1527 which is meaningless for a long time. Adjust comments.
1528 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
1529 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
1531 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
1533 * window.c (decode_next_window_args): Update window arg after
1534 calling decode_live_window and so fix crash reported at
1535 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
1536 by Juanma Barranquero <lekktu@gmail.com>.
1537 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
1538 * font.c (Ffont_at): Likewise.
1540 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
1542 * widget.c (resize_cb): New function.
1543 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
1544 (EmacsFrameResize): Check if all is up to date before changing frame
1547 2012-11-02 Eli Zaretskii <eliz@gnu.org>
1549 Implement backtrace output for fatal errors on MS-Windows.
1550 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
1551 (BACKTRACE_LIMIT_MAX): New macro.
1552 (w32_backtrace): New function.
1553 (emacs_abort): Use w32_backtrace when the user chooses not to
1554 attach a debugger. Update the text of the abort dialog.
1556 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
1558 Window-related stuff cleanup here and there.
1559 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
1560 Use decode_any_window.
1561 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
1562 * xdisp.c (Fformat_mode_line): Likewise.
1563 * font.c (Ffont_at): Use decode_live_window.
1564 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
1565 * window.c (decode_next_window_args): Likewise.
1566 (decode_any_window): Remove static.
1567 * window.h (decode_any_window): Add prototype.
1568 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
1569 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
1572 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
1574 Remove pad from struct input_event.
1575 * termhooks.h (struct input_event): Remove padding field.
1577 * keyboard.c (event_to_kboard): Simplify because frame_or_window
1578 member is never cons for a long time. Adjust comment.
1579 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
1580 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
1581 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
1582 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
1584 2012-11-01 Eli Zaretskii <eliz@gnu.org>
1586 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
1588 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
1590 Fix crash when using Emacs as commit editor for git (Bug#12697).
1591 * callproc.c (setpgrp): Remove macro, as we now use setpgid
1592 and it is configured in conf_post.h.
1593 (Fcall_process): Don't invoke both setsid and setpgid; the former
1594 is enough, if it exists.
1595 * callproc.c (Fcall_process, child_setup):
1596 * process.c (create_process): Use setpgid.
1597 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
1599 * dispnew.c (init_display): Initialize the foreground group
1600 if we are running a tty display.
1601 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
1602 * lisp.h (init_foreground_group): New decl.
1603 * sysdep.c (inherited_pgroup): New static var.
1604 (init_foreground_group, tcsetpgrp_without_stopping)
1605 (narrow_foreground_group, widen_foreground_group): New functions.
1606 (init_sys_modes): Narrow foreground group.
1607 (reset_sys_modes): Widen foreground group.
1609 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
1611 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
1613 2012-10-31 Martin Rudalics <rudalics@gmx.at>
1615 * minibuf.c (read_minibuf): Restore current buffer since
1616 choose_minibuf_frame calling Fset_frame_selected_window may
1617 change it (Bug#12766).
1619 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
1621 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
1623 2012-10-30 Kenichi Handa <handa@gnu.org>
1625 * font.c (Ffont_at): If WINDOW is specified and it is not
1626 displaying the current buffer, signal an error.
1628 2012-10-29 Daniel Colascione <dancol@dancol.org>
1630 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
1631 In preparation for fixing bug#12739, move these functions from
1634 * coding.h, coding.c: ... to here, and compile them only when
1635 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
1636 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
1638 2012-10-28 Eli Zaretskii <eliz@gnu.org>
1640 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
1641 (timer_loop, getitimer, setitimer): Use it instead of
1642 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
1644 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
1647 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
1649 * nsterm.m (NO_APPDEFINED_DATA): New define.
1650 (last_appdefined_event_data): New variable
1651 (last_appdefined_event): Remove.
1652 (ns_select): Initialize t from last_appdefined_event_data instead
1653 of [last_appdefined_event data1].
1654 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
1655 remove last_appdefined_event (Bug#12698).
1657 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
1659 * frame.c (x_set_font): Catch internal error.
1661 2012-10-27 Eli Zaretskii <eliz@gnu.org>
1663 Avoid overflow in w32 implementation of interval timers.
1664 When possible, for ITIMER_PROF count only times the main thread
1666 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
1667 'volatile ULONGLONG' types. All the other data which was
1668 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
1669 (GetThreadTimes_Proc): New typedef.
1670 (w32_get_timer_time): New function, returns a suitable time value
1672 (timer_loop): Enter critical section when accessing ULONGLONG
1673 values of the itimer_data struct, as these accesses are no longer
1674 atomic. Call 'w32_get_timer_time' instead of 'clock'.
1675 Remove unused variable.
1676 (init_timers): Initialize s_pfn_Get_Thread_Times.
1677 (start_timer_thread): Don't assign itimer->caller_thread here.
1678 (getitimer): Assign itimer->caller_thread here.
1679 (setitimer): Always call getitimer to get the value of ticks_now.
1680 (sys_spawnve): Avoid compiler warning about format mismatch.
1682 2012-10-26 Eli Zaretskii <eliz@gnu.org>
1684 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
1685 mouse movement events if the menu bar is active. This avoids
1686 producing a busy "hour-glass" cursor by Windows if the mouse
1687 pointer is positioned over a tooltip shown for some menu item.
1689 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
1691 Don't assume process IDs fit in int.
1692 * emacs.c (shut_down_emacs) [!DOS_NT]:
1693 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
1694 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
1695 Use pid_t, not int, to store process IDs, as 'int'
1696 is not wide enough on a few platforms (e.g., AIX and IRIX).
1698 2012-10-23 Kenichi Handa <handa@gnu.org>
1700 The following change is to make face-font-rescale-alist work
1701 correctly for non-ASCII fonts.
1703 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
1704 (font_open_for_lface): Handle Vface_font_rescale_alist.
1706 2012-10-23 Chong Yidong <cyd@gnu.org>
1708 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
1710 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>
1712 * nsfont.m (nsfont_open, ns_glyph_metrics): Force integer advancement
1714 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
1716 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
1719 2012-10-21 Glenn Morris <rgm@gnu.org>
1721 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
1723 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
1725 Port to OpenBSD 5.1.
1726 * frame.c (Fmouse_position, Fmouse_pixel_position):
1727 * xdisp.c (produce_stretch_glyph):
1728 Declare local vars only when they're needed.
1729 This is clearer and avoids a warning on OpenBSD about unused vars.
1730 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
1731 This is safer, and avoids OpenBSD warnings about unused vars.
1732 * keyboard.c (record_menu_key): Remove unnecessary decl.
1733 (poll_timer): Define only if POLL_FOR_INPUT is defined.
1734 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
1735 as our definition clashes with OpenBSD's.
1736 * xfaces.c (load_face_colors, check_lface_attrs)
1737 (get_lface_attributes_no_remap, get_lface_attributes)
1738 (lface_fully_specified_p, x_supports_face_attributes_p)
1739 (tty_supports_face_attributes_p, face_fontset, realize_face)
1740 (realize_x_face, realize_tty_face):
1741 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
1742 merely Lisp_Object *. This is more informative and avoids
1743 a warning on OpenBSD about accessing beyond an object's size.
1745 2012-10-20 Chong Yidong <cyd@gnu.org>
1747 * lread.c (Fload): Doc fix (Bug#12592).
1749 2012-10-19 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny change)
1751 * font.c (Ffont_at): Fix previous change.
1753 2012-10-19 Eli Zaretskii <eliz@gnu.org>
1755 * puresize.h (BASE_PURESIZE): Bump the base value to 1700000.
1756 See http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00593.html
1759 * alloc.c (NSTATICS): Decrease to 0x800.
1761 2012-10-19 Stefan Monnier <monnier@iro.umontreal.ca>

1766 2012-10-18 Jan Djärv <jan.h.d@swipnet.se>
1768 * nsterm.m (ns_select): Check writefds before call to
1769 FD_ISSET (Bug#12668).
1771 2012-10-18 Daniel Colascione <dancol@dancol.org>
1773 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
1774 (staticpro): If we run out of staticpro slots, die with an
1775 informative error instead of just calling emacs_abort.
1777 2012-10-18 Martin Rudalics <rudalics@gmx.at>
1779 Fix two flaws reported by Dmitry Antipov.
1780 * window.c (Ftemp_output_buffer_show): Remove.
1781 (Fwindow_vscroll, Fset_window_vscroll): Use decode_live_window.
1782 (syms_of_window): Remove defsubr for Stemp_output_buffer_show.
1784 2012-10-17 Eli Zaretskii <eliz@gnu.org>

1789 ($(BLD)/unexw32.$(O)):
1790 ($(BLD)/fileio.$(O)):
1791 ($(BLD)/dispnew.$(O)): Update dependencies.
1793 * w32term.h (w32_initialize_display_info, initialize_w32_display):
1796 * w32proc.c: Include ctype.h.
1798 * w32.h (init_environment, check_windows_init_file)
1799 (syms_of_ntproc, syms_of_ntterm, dostounix_filename)
1800 (unixtodos_filename, init_winsock, srandom, random, sys_pipe)
1801 (set_process_dir, sys_spawnve, register_child, sys_sleep, getwd)
1802 (sys_link): Add prototypes.
1804 * w32.c: Include w32select.h.
1805 (sys_access, e_malloc, sys_select): Add prototypes.
1806 (emacs_gnutls_pull): 'timeout' is now EMACS_TIME, not struct timeval.
1808 * vm-limit.c [WINDOWSNT]: Include w32heap.h.
1810 * unexw32.c: Include lisp.h and w32.h.
1812 * term.c [WINDOWSNT]: Include w32term.h.
1814 * process.c [WINDOWSNT]: Add prototype of sys_select.
1816 * fileio.c [WINDOWSNT]: Include w32.h.
1818 * dispnew.c [WINDOWSNT]: Include w32.h.
1820 * cygw32.c (Fcygwin_convert_path_to_windows)
1821 (Fcygwin_convert_path_from_windows): Use EQ to compare 2
1822 Lisp_Object values. (Bug#12661)
1824 * w32fns.c (w32_msg_pump): Use XIL instead of casting an integer
1825 to Lisp_Object. (Bug#12661)
1827 2012-10-17 Kenichi Handa <handa@gnu.org>
1829 * xdisp.c (reseat_1): Make the information stored in it->cmp_it

1835 reset its buffer pointer to NULL (Bug#12652).
1837 2012-10-17 Dmitry Antipov <dmantipov@yandex.ru>
1839 Do not verify indirection counters of killed buffers (Bug#12579).
1840 * buffer.h (BUFFER_CHECK_INDIRECTION): New macro.
1841 * buffer.c (compact_buffer, set_buffer_internal_1): Use it.
1843 2012-10-16 Dmitry Antipov <dmantipov@yandex.ru>
1845 * alloc.c (Fmake_byte_code): Fix typo in comment.
1846 * print.c (print_interval): Define as static to match prototype.
1847 * indent.c (disptab_matches_widthtab, recompute_width_table):
1850 2012-10-16 Dmitry Antipov <dmantipov@yandex.ru>
1852 * editfns.c (get_system_name): Remove.
1853 * lisp.h (get_system_name): Remove prototype.

1859 * dbusbind.c: Add comment explaining reason for previous change.
1861 2012-10-15 Martin Rudalics <rudalics@gmx.at>
1863 * window.c (Fwindow_end): Rewrite check whether cached position
1864 can be used (Bug#12600).
1865 (resize_frame_windows, grow_mini_window, shrink_mini_window):
1866 Set windows_or_buffers_changed.
1868 2012-10-15 Daniel Colascione <dancol@dancol.org>
1870 * dbusbind.c: Fix cygw32 build break when compiling with dbus
1871 enabled by undefining the symbol "interface", which the platform
1872 headers define to something incompatible.
1874 2012-10-14 Daniel Colascione <dancol@dancol.org>
1876 * image.c (init_tiff_functions, init_imagemagick_functions)
1877 (init_svg_functions): Fix cygw32 build break by using these
1878 functions only when WINDOWSNT _and_ HAVE_NTGUI.

1899 Fix some stat-related races.
1900 * fileio.c (Fwrite_region): Avoid race condition if a file is
1901 removed or renamed by some other process immediately after Emacs
1902 writes it but before Emacs stats it. Do not assume that stat (or
1904 * image.c (slurp_file): Resolve the file name with fopen + fstat
1905 rather than stat + fopen.
1906 (pbm_read_file) [0]: Remove unused code with stat race.
1907 * process.c (allocate_pty) [HAVE_PTYS && !PTY_ITERATION && !PTY_OPEN]:

1931 * makefile.w32-in ($(BLD)/fileio.$(O)): Add sys/file.h.
1933 * fileio.c (check_existing): New function.
1934 (make_temp_name, Ffile_exists_p, Ffile_writable_p): Call it
1935 instead of calling 'stat', when what's needed is to check whether
1936 a file exists. This avoids expensive system calls on MS-Windows.
1939 * w32.c (init_environment): Call 'check_existing' instead of 'stat'.
1941 * lread.c (openp) [WINDOWSNT]: Call 'access' instead of 'stat' to

1946 2012-10-12 Jan Djärv <jan.h.d@swipnet.se>
1948 * nsfont.m (nsfont_open): Remove font cache, it is not GC correct.

1992 * w32select.c (waiting_for_input): Declare by including "keyboard.h"
1993 instead of having a wrong decl.

2032 * process.c (wait_reading_process_output):
2033 Use unsigned for counter where wraparound-on-overflow is desired,
2034 since unsigned is guaranteed to have that behavior and signed is not.
2035 (read_char): Use ptrdiff_t for string length.
2036 (get_input_pending): Remove first argument, since it was always
2037 the same pointer-to-int (now pointer-to-boolean) &input_pending,
2038 and behave as if it had that value. Return new value of
2039 input_pending. All callers changed.
2040 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
2041 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's
2043 * keymap.c (push_key_description): Omit last arg, which was always 1.
2044 All callers changed.
2046 * regex.c (immediate_quit) [emacs]: Remove duplicate decl.

2064 Don't include termopts.h.
2066 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>
2068 * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers.
2070 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
2072 * commands.h (immediate_quit): Remove duplicate decl.
2074 2012-10-09 Jan Djärv <jan.h.d@swipnet.se>
2076 * nsfont.m (Vfonts_in_cache): Remove, not needed as font.c handles
2078 (nsfont_open): Remove setting of Vfonts_in_cache.
2079 (syms_of_nsfont): Remove initialization of Vfonts_in_cache.
2081 2012-10-09 Eli Zaretskii <eliz@gnu.org>
2083 * w32fns.c (w32_last_error): Change the return value to DWORD, to
2084 match what GetLastError returns. Explain why the function is
2087 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
2088 'is_tooltip_frame', to avoid confusion with its global namesake.
2090 2012-10-08 Daniel Colascione <dancol@dancol.org>
2092 * xdisp.c (start_hourglass): Call w32_note_current_window when
2093 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
2094 build that caused Emacs to display the hourglass cursor forever.
2096 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
2097 which is broken under remote desktop, calculate the number of
2098 colors available for a display based on the display's number of
2099 planes and number of bits per pixel per plane. (bug#10397).
2101 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
2103 * nsfont.m (Vfonts_in_cache): New variable.
2104 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
2105 are used. Add cached fonts to Vfonts_in_cache.
2106 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
2108 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
2110 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
2112 (FONT_H): Define after FRAME_H.
2113 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
2114 Update dependencies.
2116 * w32term.c: Remove leftover declaration of keyboard_codepage.
2118 2012-10-08 Eli Zaretskii <eliz@gnu.org>
2120 * makefile.w32-in (FONT_H): Add $(FRAME_H).
2121 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
2122 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
2123 (GLOBAL_SOURCES): Add cygw32.c.
2124 ($(BLD)/unexw32.$(O)):
2126 ($(BLD)/w32console.$(O)):
2127 ($(BLD)/w32fns.$(O)):
2128 ($(BLD)/w32heap.$(O)):
2129 ($(BLD)/w32menu.$(O)):
2130 ($(BLD)/w32proc.$(O)): Add w32common.h.
2132 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
2134 (x_to_w32_color): Don't modify the argument, modify a copy instead.
2136 2012-10-08 Daniel Colascione <dancol@dancol.org>
2138 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
2139 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
2140 accidental message numbering hole. Change other messages to
2143 * w32select.h (HAVE_W32SELECT): Remove.
2145 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
2146 w32common.h instead of w32heap.h.
2148 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
2149 (get_allocation_unit, get_processor_type, get_w32_major_version)
2150 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
2151 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
2152 (OS_NT, os_subtype, cache_system_info): Move declarations to
2155 * w32heap.c: Include w32common.h.
2156 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
2157 (w32_minor_version, w32_build_number, w32_subtype):
2158 Remove duplicate definitions.
2160 * w32fns.c: Include w32common.h; include w32heap.h only in
2163 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
2164 Use `report_file_error' instead of `error' in order to better
2165 inform users of what went wrong. Increase NTGUI_UNICODE file
2166 dialog box file name length to 32k, the maximum allowed by the NT
2169 * w32common.h: New file.
2170 (ROUND_UP, ROUND_DOWN, get_page_size)
2171 (get_allocation_unit, get_processor_type, get_w32_major_version)
2172 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
2173 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
2174 (OS_NT, os_subtype, cache_system_info): Move here.
2176 * unexw32.c, unexcw.c: Include w32common.h.
2178 * emacs.c (main): Use (defined (WINDOWSNT) || defined
2179 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
2180 to call syms_of_w32select.
2182 * cygw32.h: Remove obsolete EXFUN declarations.
2184 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
2186 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
2187 of w32inevt.o from SOME_MACHINE_OBJECTS.
2189 2012-10-08 Daniel Colascione <dancol@dancol.org>
2191 * image.c: Permanent fix for JPEG compilation issue --- limit
2192 jpeglib `boolean' redefinition to Cygwin builds.
2194 2012-10-08 Eli Zaretskii <eliz@gnu.org>
2196 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
2198 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
2201 2012-10-08 Daniel Colascione <dancol@dancol.org>
2203 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
2204 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
2205 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
2206 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
2207 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
2208 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
2209 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
2210 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
2211 now a supported configuration.
2213 * Makefile.in: consolidate image variables into LIBIMAGE; add
2214 W32_OBJ and W32_LIBS. Compile new files.
2217 (_DebPrint) declare tracing facility for W32 debugging. We need
2218 to unify tracing later.
2220 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
2221 unconditional use of W32 Unicode functions. Cygwin runs only on
2222 100% Unicode operating systems.
2224 * cygw32.c: New file. Define Cygwin-specific facilities.
2225 (Fcygwin_convert_path_to_windows)
2226 (Fcygwin_convert_path_from_windows): New user functions for
2227 accessing Cygwin path-munging routines.
2229 * cygw32.h: New file.
2230 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
2231 UTF-16LE strings temporarily inside non-Lisp-visible string
2234 (w32_strerror): Just what it says on the tin.
2236 * emacs.c: Make the NS fork-then-exec code for daemon-launching
2237 also run for Cygwin; both systems have the same problem with using
2238 GUI facilities in a forked child. Also call syms_of_cygw32,
2239 syms_of_w32select in correct places.
2241 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
2242 needs fork-then-exec for daemon launching.
2244 * font.h: Include frame.h.
2246 * image.c: Use the image library cache machinery only when we're
2247 compiling for native WINDOWSNT; Cygwin can use shared libraries
2248 like any other Unixlike system.
2250 * keyboard.c: Clarify a comment regarding the input loop.
2252 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
2253 functions directly instead of trying to detect at runtime that our
2254 host operating system supports them. We make this change for two
2255 reasons: Cygwin lacks support for the multibyte character
2256 conversion functions used by the legacy menu code, and Cygwin
2257 never needs to rely on non-Unicode APIs.
2259 * unexw32.c (hinst): Declare extern.
2261 * w32.c: Change header order;
2262 (w32_strerror): Move to w32fns.c because we need it for
2263 non-WINDOWSNT builds.
2265 * w32.h: Add #error macro to make sure we don't include w32.h for
2266 Cygwin builds. Remove w32select declarations.
2268 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
2269 w32fns.c. w32console.c is WINDOWSNT-only.
2271 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
2272 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
2274 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
2275 (w32_major_version, w32_minor_version, w32_build_number)
2276 (os_subtype, sound_type): Define here
2277 (w32_defined_color): Make color parameter const for consistency
2278 with other _defined_color functions.
2279 (w32_createwindow): Unconditionally call w32_init_class instead of
2280 doing so only when hprevinst is non-NULL. Plumbing hprevinst
2281 through the code is complex and unnecessary because class
2282 registration is practically free.
2283 (w32_name_of_message): New EMACSDEBUG-only function.
2284 (Fset_message_beep): Move here
2285 (Fx_open_connection): Require that the display name for Windows be
2286 "w32" for consistency, emacsclient disambiguation, and maybe, one
2287 day, multi-window-system support.
2288 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
2289 Cygwin files for W32 GUI facilities, since these clearly don't
2290 expect Cygwin names.
2291 (_DebPrint): Define.
2292 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
2293 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
2294 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
2295 (w32_last_error): Remove.
2297 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
2299 * w32heap.c (syspage_mask): Declare here.
2300 (cache_system_info): Remove.
2302 * w32inevt.c (faked_key): Define globally, not statically.
2303 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
2304 (w32_console_toggle_lock_key): Move to w32fns.c.
2306 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
2308 * w32proc.c (_DebPrint): Move to w32fns.c.
2309 * w32select.c: Include string.h, stdio.h for Cygwin.
2310 * w32select.h: New File.
2312 * w32term.c: Include io.h for non-CYGWIN builds; needed for
2314 (w32_message_fd): New variable. Under Cygwin, holds the file
2315 descriptor the system used to tell us about pending thread
2318 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
2319 that prevented compilation under non-WINDOWSNT systems.
2321 (w32_initialize): Open /dev/windows and assign it to
2322 w32_message_fd. Provide w32 feature.
2324 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
2325 (WM_EMACS_INPUT_READY): add.
2326 (prepend_msg, w32_message_fd): Declare globally.
2329 (keyboard_handle): Use only when WINDOWSNT.
2330 (notify_msg_ready): New function. Posts a message to the main
2331 thread's message queue under CYGWIN, which wakes up the main
2332 thread from select(2) by making the /dev/windows file descriptor
2333 ready. Under WINDOWSNT, it sets an event the same way the old
2336 (post, prepend_msg): Actually call notify_msg_ready instead of
2337 setting the input event directly.
2339 2012-10-07 Eli Zaretskii <eliz@gnu.org>
2341 * ralloc.c (relinquish): If a heap is ready to be relinquished,
2342 but it still has blocs in it, don't return it to the system,
2343 instead of aborting. (Bug#12402)
2345 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
2347 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
2349 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
2350 MAC_OS_X_VERSION_10_6.
2351 (syms_of_nsterm): Remove comment about Panther and above for
2353 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.

2378 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
2380 Improve sys_siglist detection.
2381 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
2382 defined as a macro, as is done in Solaris.
2383 (sys_siglist_entries): New macro.
2384 (save_strsignal): Use it.
2385 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
2386 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
2388 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
2390 * nsfns.m (Fx_create_frame): Call x_default_parameter with
2391 fullscreen/Fullscreen.
2393 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
2394 tobar_height is new.
2396 * nsterm.m (x_make_frame_visible): Check for fullscreen.
2397 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
2398 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
2399 (windowDidResize:): Check for correct window if old style fullscreen.
2400 Capitalize word in comment. Remove incorrect comment.
2401 (initFrameFromEmacs:): tbar_height renamed tibar_height.

2411 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
2413 2012-10-05 Eli Zaretskii <eliz@gnu.org>
2415 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
2417 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
2418 that time stamps of directories could also be changed.
2419 Don't request the too broad GENERIC_WRITE, only the more restrictive
2420 FILE_WRITE_ATTRIBUTES access rights.
2422 * fileio.c (Fset_file_times): Special-case ignoring errors for
2423 directories only on MSDOS, not on MS-Windows.
2425 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
2427 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
2429 2012-10-04 Eli Zaretskii <eliz@gnu.org>
2431 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
2432 see whether CreateFile failed.
2434 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
2436 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
2437 to avoid similar races.
2438 * keyboard.c (pending_signals): Now bool, not int.
2440 Port timers to OpenBSD, plus check for timer failures.
2441 OpenBSD problem reported by Han Boetes.
2442 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
2444 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
2445 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
2446 like OpenBSD, which has timer_settime but does not declare it.
2447 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
2448 whether to use itimerspec-related primitives. All uses of
2449 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
2451 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
2453 * profiler.c (handle_profiler_signal): Fix a malloc race
2454 that caused Emacs to hang on Fedora 17 when profiling Lisp.
2456 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
2458 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
2460 2012-10-02 Eli Zaretskii <eliz@gnu.org>
2462 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
2463 consistent with the change in return value of 'safe_strsignal'.
2465 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
2467 Prefer plain 'static' to 'static inline' (Bug#12541).
2468 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
2469 (bidi_set_sor_type, bidi_push_embedding_level)
2470 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)

2475 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
2476 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
2477 Now 'static', not 'static inline'.
2479 Count overruns when profiling; change units to ns.
2480 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
2481 Give extra weight to samples after overruns, to attempt to count
2482 the time more accurately.
2483 (setup_cpu_timer): Change sampling interval units from ms to ns, since
2484 the underlying primitives nominally do ns.
2485 (Fprofiler_cpu_start): Document the change. Mention that
2486 the sampling intervals are only approximate.
2488 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
2490 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
2492 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
2493 case for the special 0 coding-system.
2495 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
2496 (Fmake_overlay): Remove redundant tests.
2497 (fix_start_end_in_overlays): Remove redundant recentering.
2499 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
2501 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
2502 Update dependencies.
2504 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
2506 Fix a malloc race condition involving strsignal.
2507 A signal can arrive in the middle of a malloc, and Emacs's signal
2508 handler can invoke strsignal, which can invoke malloc, which is
2509 not portable. This race condition bug makes Emacs hang on GNU/Linux.
2510 Fix it by altering the signal handler so that it does not invoke
2512 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
2513 * process.c (status_message): Use const pointer, in case strsignal
2514 is #defined to safe_strsignal.
2515 * sysdep.c (sys_siglist, init_signals): Always define and
2516 initialize a substitute sys_siglist if the system does not define
2517 one, even if HAVE_STRSIGNAL.
2518 (safe_strsignal): Rename from strsignal. Always define,
2519 using sys_siglist. Return a const pointer.
2520 * syssignal.h (safe_strsignal): New decl.
2521 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
2523 2012-10-01 Eli Zaretskii <eliz@gnu.org>
2525 * w32proc.c (timer_loop): Fix code that waits for timer
2526 expiration, to avoid high CPU usage.
2528 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
2530 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
2531 (sweep_weak_table): Remove redundant prototypes.
2533 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
2535 * emacs.c: Move the inclusion of TERM_HEADER after including
2536 windows.h on WINDOWSNT. This avoids compilation problems with
2539 2012-10-01 Eli Zaretskii <eliz@gnu.org>
2541 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
2542 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
2543 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
2544 as the previous version used 'void *'.
2546 * ralloc.c (ROUNDUP): Fix last change.
2547 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
2550 * w32proc.c <disable_itimers>: New static flag.
2551 (init_timers): Initialize it to zero, after creating the critical
2552 sections used by the timer threads.
2553 (term_timers): Set to 1 before deleting the critical sections.
2554 (getitimer, setitimer): If disable_itimers is non-zero, return an
2555 error indication without doing anything. Reported by Fabrice
2556 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
2557 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
2559 [!HAVE_SETITIMER]: Behave as the previous version that didn't
2562 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
2563 term_ntproc after all the other bookkeeping, to get timers working
2564 as long as possible.
2566 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
2568 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
2569 Suggested by Juri Linkov in
2570 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
2572 Prefer plain 'static' to 'static inline' (Bug#12541).
2573 With static functions, modern compilers inline pretty well by
2574 themselves; advice from programmers often hurts as much as it helps.
2575 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
2576 this change shrinks the text size of the Emacs executable by 1.1%
2577 without affecting CPU significantly in my benchmark.
2578 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)

2658 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
2660 Revert the FOLLOW-SYMLINKS change for file-attributes.
2661 Doing it right would require several changes to Tramp, and there's
2662 not enough time to get that tested before the freeze today.
2663 * dired.c (directory_files_internal, Ffile_attributes):
2666 * frame.c (x_report_frame_params): Port better to wider ints.
2667 Do not assume that EMACS_UINT is the same width as uprintmax_t,
2668 or that pointers can be printed in 15 decimal digits.
2669 Avoid GCC warnings if EMACS_UINT is wider than a pointer.

2705 * vm-limit.c (lim_data): Now size_t.
2706 (check_memory_limits): Adjust prototypes of real_morecore and
2707 __morecore to receive argument of type ptrdiff_t. Use size_t for

2779 to hourglass timer expiration.
2780 (start_hourglass, cancel_hourglass, DEFAULT_HOURGLASS_DELAY):
2781 Remove, no longer used.
2782 (w32_note_current_window, show_hourglass, hide_hourglass):
2783 New functions, in support of hourglass cursor display similar to other

2787 * xdisp.c (start_hourglass, cancel_hourglass): Now used on
2789 (start_hourglass) [WINDOWSNT]: Call w32_note_current_window.
2791 * w32.h (init_timers, term_timers): Add prototypes.
2793 2012-09-30 Kenichi Handa <handa@gnu.org>
2795 * coding.c (decode_coding_ccl, encode_coding_ccl): Pay attention
2796 to the buffer relocation which may be caused by ccl_driver.

2832 (EmacsFSWindow): New interface for fullscreen.
2834 2012-09-30 Juanma Barranquero <lekktu@gmail.com>
2836 * makefile.w32-in ($(BLD)/profiler.$(O)): Update dependencies.
2838 2012-09-30 Chong Yidong <cyd@gnu.org>
2840 * fns.c (Frandom): Doc fix.

2845 (Qwindow_size): New symbol replacing Qtemp_buffer_resize.
2847 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
2849 * syssignal.h (PROFILER_CPU_SUPPORT): Don't define if PROFILING.
2850 Suggested by Eli Zaretskii in
2851 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00811.html>.
2853 2012-09-30 Eli Zaretskii <eliz@gnu.org>
2855 * profiler.c (Fprofiler_cpu_stop): Use timer_settime only if
2856 HAVE_TIMER_SETTIME is defined.
2858 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
2860 Profiler improvements: more-accurate timers, overflow checks.
2861 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
2862 signal.h, setjmp.h. Include systime.h instead.
2863 (saturated_add): New function.
2864 (record_backtrace, current_sample_interval): Use EMACS_INT, not size_t.
2865 (record_backtrace, handle_profiler_signal): Saturate on fixnum overflow.
2866 (profiler_timer, profiler_timer_ok) [HAVE_TIMER_SETTIME]:
2868 (enum profiler_cpu_running): New enum.
2869 (profiler_cpu_running): Now of that enum type, not bool.
2870 All uses changed to store the new value.
2871 (handle_profiler_signal): Rename from sigprof_handler_1,
2872 for consistency with other handlers. Do not check whether
2873 cpu_log is a hash-table if garbage collecting, since it
2874 doesn't matter in that case.
2875 (deliver_profiler_signal): Rename from sigprof_handler,
2876 for consistency with other handlers.
2877 (setup_cpu_timer): New function, with much of what used to be in
2878 Fprofiler_cpu_start. Check for out-of-range argument.
2879 Prefer timer_settime if available, and prefer
2880 thread cputime clocks, then process cputime clocks, then
2881 monotonic clocks, to the old realtime clock. Use make_timeval
2882 to round more-correctly when falling back to setitimer.
2883 (Fprofiler_cpu_start): Use it.
2884 (Fprofiler_cpu_stop): Prefer timer_settime if available.
2885 Don't assume that passing NULL as the 2nd argument of setitimer
2886 is the same as passing a pointer to all-zero storage.
2887 Ignore SIGPROF afterwards.
2888 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
2889 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
2890 non-fatal signal handlers. Ignore SIGPROF on startup.
2891 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
2892 in profiler.c, since sysdep.c now uses it.
2894 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.
2895 Suggested by Eli Zaretskii in

2948 * character.h (MAYBE_UNIFY_CHAR): Remove.
2949 * charset.c, charset.h (maybe_unify_char): Now static.
2950 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
2951 Since this stuff is now private to charset.c, there's no need for
2952 a public macro and no need to inline by hand.

2985 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>
2987 Prefer POSIX timers if available.
2988 They avoid a race if the timer is too close to the current time.

3016 * w32.h (Vlibrary_cache): Do not declare.
3018 2012-09-25 Eli Zaretskii <eliz@gnu.org>
3020 * w32proc.c (sys_signal): Handle all signals defined by the
3021 MS-Windows runtime, not just SIGCHLD. Actually install the signal
3022 handlers for signals supported by Windows. Don't override
3023 term_ntproc as the handler for SIGABRT.
3024 (sigaction): Rewrite to call sys_signal instead of duplicating its
3026 (sys_kill): Improve commentary.
3028 * w32.c (term_ntproc): Accept (and ignore) one argument, for
3029 consistency with a signature of a signal handler. All callers
3031 (init_ntproc): Accept an argument DUMPING. If dumping, don't
3032 install term_ntproc as a signal handler for SIGABRT, as that
3033 should be done by the dumped Emacs.
3035 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
3037 * w32select.c (term_w32select): Protect against repeated
3038 invocation by setting clipboard_owner to NULL after calling
3041 * emacs.c (shut_down_emacs, main): Adapt the calls to init_ntproc
3042 and term_ntproc to their modified signatures.
3044 * character.c (char_string, string_char): Remove calls to

3056 when encountering an unknown bytecode.
3058 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
3060 image.c, indent.c: Use bool for booleans.

3063 * image.c: Omit unnecessary static decls.
3064 (x_create_bitmap_mask, x_build_heuristic_mask):

3102 Move pid_t related decls out of lisp.h.
3103 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
3104 (interruptible_wait_for_termination):
3105 Move these decls from lisp.h to syswait.h, since they use pid_t.
3106 Needed on FreeBSD; see Herbert J. Skuhra in
3107 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.

3154 2012-09-23 Eli Zaretskii <eliz@gnu.org>
3156 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
3157 fatal_error_backtrace.
3159 * w32proc.c (sys_kill): Undo last change: don't do anything when
3160 invoked to deliver SIGABRT to our own process. This is now
3161 handled by emacs_raise.
3163 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
3165 * w32term.c (w32_read_socket): Remove leftover reference to
3166 interrupt_input_pending.
3168 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
3170 Do not use SA_NODEFER.
3171 Problem reported by Dani Moncayo in
3172 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
3174 * sysdep.c (emacs_abort): Do not reset signal handler.
3175 * emacs.c (terminate_due_to_signal): Reset signal handler here.
3176 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
3177 wanted even on POSIXish hosts, and it doesn't work on Windows.
3179 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
3181 * xterm.c (x_term_init): Call fixup_locale before and after calling
3182 gtk_init (Bug#12392).
3184 2012-09-23 Chong Yidong <cyd@gnu.org>
3186 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
3187 Vdynamic_library_alist.
3189 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
3190 (Fgnutls_available_p): Caller changed.
3192 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
3193 (Flibxml_parse_xml_region): Likewise.
3195 * dispextern.h (struct image_type): Remove arg from init function.
3197 * image.c (Finit_image_library, lookup_image_type)
3198 (define_image_type): Remove now-unneeded second arg.
3199 (init_xpm_functions, init_png_functions, init_jpeg_functions)
3200 (init_tiff_functions, init_gif_functions, init_svg_functions):
3201 Arglist and w32_delayed_load calling convention changed.
3202 (gs_type): Remove init_gs_functions; there is no such function.
3203 (valid_image_p, make_image): Fix caller to lookup_image_type.
3205 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
3207 Simplify and avoid signal-handling races (Bug#12471).
3209 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
3210 Avoid recursive loop if there's a fatal error in the function itself.
3211 * atimer.c (pending_atimers):
3212 * blockinput.h: Don't include "atimer.h"; no longer needed.
3213 (interrupt_input_pending): Remove. All uses removed.
3214 pending_signals now counts both atimers and ordinary interrupts.
3215 This is less racy than having three separate pending-signal flags.
3216 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
3218 Rename from their upper-case counterparts BLOCK_INPUT,
3219 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
3220 INPUT_BLOCKED_P, and turn into functions. All uses changed.
3221 This makes it easier to access volatile variables more accurately.
3222 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
3223 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
3224 that's more reliable if the code is buggy and sets
3225 interrupt_input_blocked to a negative value. All uses changed.
3226 * atimer.c (deliver_alarm_signal):
3227 Remove. No need to deliver this to the parent; any thread can
3228 handle this signal now. All uses replaced by underlying handler.
3229 * atimer.c (turn_on_atimers):
3230 * dispnew.c (handle_window_change_signal):
3231 * emacs.c (handle_danger_signal):
3232 * keyboard.c (kbd_buffer_get_event):
3233 Don't reestablish signal handler; not needed with sigaction.
3234 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
3236 Rework to avoid unnecessary accesses to volatile variables.
3237 (UNBLOCK_INPUT_TO): Now a function.
3238 (totally_unblock_input, unblock_input): New decls.
3239 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
3240 (init_data): Remove. Necessary stuff now done in init_signal.
3241 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
3242 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
3243 (fatal_error_code): Remove; no longer needed.
3244 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
3245 it doesn't always backtrace. All uses changed. No need to reset
3246 signal to default, since sigaction and/or die does that for us now.
3247 Use emacs_raise (FOO), not kill (getpid (), FOO).
3248 (main): Check more-accurately whether we're dumping.
3249 Move fatal-error setup to sysdep.c
3250 * floatfns.c: Do not include "syssignal.h"; no longer needed.
3251 * gtkutil.c (xg_get_file_name, xg_get_font):
3252 Remove no-longer-needed signal-mask manipulation.
3253 * keyboard.c, process.c (POLL_FOR_INPUT):
3254 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
3255 * keyboard.c (read_avail_input): Remove.
3256 All uses replaced by gobble_input.
3257 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
3258 (kbd_buffer_store_event_hold, gobble_input):
3259 (record_asynch_buffer_change) [USABLE_SIGIO]:
3260 (store_user_signal_events):
3261 No need to mess with signal mask.
3262 (gobble_input): If blocking input and there are terminals, simply
3263 set pending_signals to 1 and return. All hooks changed to not
3264 worry about whether input is blocked.
3265 (process_pending_signals): Clear pending_signals before processing
3266 them, in case a signal comes in while we're processing.
3267 By convention callers now test pending_signals before calling us.
3268 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
3269 New functions, to support changes to blockinput.h.
3270 (handle_input_available_signal): Now extern.
3271 (reinvoke_input_signal): Remove. All uses replaced by
3273 (quit_count): Now volatile, since a signal handler uses it.
3274 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
3275 All callers changed. Block SIGINT only if not already blocked.
3276 Clear sigmask reliably, even if Fsignal returns, which it can.
3277 Omit unnecessary accesses to volatile var.
3278 (quit_throw_to_read_char): No need to restore sigmask.
3279 * keyboard.c (gobble_input, handle_user_signal):
3280 * process.c (wait_reading_process_output):
3281 Call signal-handling code rather than killing ourselves.
3282 * lisp.h: Include <float.h>, for...
3283 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
3284 (pending_signals): Now volatile.
3285 (syms_of_data): Now const if IEEE floating point.
3286 (handle_input_available_signal) [USABLE_SIGIO]:
3287 (terminate_due_to_signal, record_child_status_change): New decls.
3288 * process.c (create_process): Avoid disaster if memory is exhausted
3289 while we're processing a vfork, by tightening the critical section
3291 (send_process_frame, process_sent_to, handle_pipe_signal)
3292 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
3294 (send_process): No need for setjmp/longjmp any more, since the
3295 SIGPIPE stuff is now gone. Instead, report an error if errno
3297 (record_child_status_change): Now extern. PID and W are now args.
3298 Return void, not bool. All callers changed.
3299 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
3300 Remove. All uses removed. This bug should be fixed now in a
3302 (wait_for_termination_1): Use waitpid rather than sigsuspend,
3303 and record the child status change directly. This avoids the
3304 need to futz with the signal mask.
3305 (process_fatal_action): Move here from emacs.c.
3306 (emacs_sigaction_flags): New function, containing
3307 much of what used to be in emacs_sigaction_init.
3308 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
3309 caught by emacs, to make races less likely.
3310 (deliver_process_signal): Rename from handle_on_main_thread.
3312 (BACKTRACE_LIMIT_MAX): Now at top level.
3313 (thread_backtrace_buffer, threadback_backtrace_pointers):
3315 (deliver_thread_signal, deliver_fatal_thread_signal):
3316 New functions, for more-accurate delivery of thread-specific signals.
3317 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
3318 (deliver_arith_signal): Handle in this thread, not
3319 in the main thread, since it's triggered by this thread.
3320 (maybe_fatal_sig): New function.
3321 (init_signals): New arg DUMPING so that we can be more accurate
3322 about whether we're dumping. Caller changed.
3323 Treat thread-specific signals differently from process-general signals.
3324 Block all signals while handling fatal error; that's safer.
3325 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
3327 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
3328 Ignore SIGPIPE unless batch.
3329 (emacs_backtrace): Output backtrace for the appropriate thread,
3330 which is not necessarily the main thread.
3331 * syssignal.h: Include <stdbool.h>.
3332 (emacs_raise): New macro.
3333 * xterm.c (x_connection_signal): Remove; no longer needed
3334 now that we use sigaction.
3335 (x_connection_closed): No need to mess with sigmask now.
3336 (x_initialize): No need to reset SIGPIPE handler here, since
3337 init_signals does this for us now.
3339 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
3341 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
3342 background rect may be larger (Bug#12245).
3344 2012-09-23 Chong Yidong <cyd@gnu.org>
3346 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
3348 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
3350 * .gdbinit: Just stop at fatal_error_backtrace.
3351 See Stefan Monnier's request in
3352 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
3353 Remove no-longer-used query of system type.
3355 2012-09-22 Chong Yidong <cyd@gnu.org>
3357 * search.c (Freplace_match): Doc fix (Bug#12325).
3359 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
3361 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
3362 (Fline_end_position): Doc fix.
3364 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
3366 2012-09-22 Chong Yidong <cyd@gnu.org>
3368 * dispextern.h (struct image_type): Add new slot, storing a type
3369 initialization function.
3371 * image.c (define_image_type): Call the image initializer function
3372 if it is defined. Arguments and return value changed.
3373 (valid_image_p, make_image): Callers changed.
3374 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
3375 (gif_type, imagemagick_type, svg_type, gs_type):
3376 Add initialization functions.
3377 (Finit_image_library): Call lookup_image_type.
3378 (CHECK_LIB_AVAILABLE): Macro deleted.
3379 (lookup_image_type): Call define_image_type here, rather than via
3380 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
3381 (syms_of_image): Move define_image_type calls for xbm_type and
3382 pbm_type to lookup_image_type.
3384 2012-09-22 Eli Zaretskii <eliz@gnu.org>
3386 * keyboard.c (timer_check_2): Move calculation of 'timers' and
3387 'idle_timers' from here ...
3388 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
3389 lists, to avoid infloops when the timer does something stupid,
3390 like reinvoke itself with the same or smaller time-out.
3393 2012-09-22 Martin Rudalics <rudalics@gmx.at>
3395 * window.c (Fsplit_window_internal): Handle only Qt value of
3396 Vwindow_combination_limit separately.
3397 (Qtemp_buffer_resize): New symbol.
3398 (Vwindow_combination_limit): New default value.
3401 2012-09-22 Eli Zaretskii <eliz@gnu.org>
3403 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
3404 the new overlay string. (Bug#10159)
3406 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
3408 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
3409 or that fprintf is async-signal-safe. POSIX doesn't require
3412 2012-09-22 Chong Yidong <cyd@gnu.org>
3414 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
3417 2012-09-22 Kenichi Handa <handa@gnu.org>
3419 * composite.c (composition_reseat_it): Handle the case that a
3420 grapheme cluster is not covered by a single font (Bug#12352).
3422 2012-09-21 Chong Yidong <cyd@gnu.org>
3424 * image.c (define_image_type): Avoid adding duplicate types to
3425 image_types (Bug#12463). Suggested by Jörg Walter.
3427 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3429 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
3430 (print_load_command_name): Add case LC_DATA_IN_CODE.
3431 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
3433 2012-09-21 Glenn Morris <rgm@gnu.org>
3435 * eval.c (Frun_hook_with_args_until_success)
3436 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
3438 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
3440 * fileio.c (Ffile_selinux_context): Only call freecon when
3441 lgetfilecon succeeded.
3442 (Fset_file_selinux_context): Likewise. (Bug#12444)
3444 2012-09-21 Eli Zaretskii <eliz@gnu.org>
3446 * xdisp.c (try_window_reusing_current_matrix): Under bidi
3447 reordering, locate the cursor by calling set_cursor_from_row; if
3448 that fails, clear the desired glyph matrix before returning a
3449 failure indication to the caller. Fixes leaving garbled display
3450 when fast scrolling with a down-key. (Bug#12403)
3451 (compute_stop_pos_backwards): Fix a typo that caused crashes while
3452 scrolling through multibyte text.
3454 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
3456 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
3457 calling mark_vectorlike since that's the one that marks the window.
3458 (mark_discard_killed_buffers): Mark the final cdr.
3459 * window.h (struct window): Move prev/next_buffers to the
3460 non-standard fields.
3461 * window.c (make_window): Initialize prev/next_buffers manually.
3463 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
3465 Omit unused arg EXPECTED from socket hooks.
3466 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
3467 * nsterm.m (ns_term_init):
3468 * termhooks.h (struct terminal.read_socket_hook):
3469 * w32inevt.c (w32_console_read_socket):
3470 * w32term.c (w32_read_socket):
3471 * xterm.c (XTread_socket):
3472 Omit unused arg EXPECTED. All callers changed.
3473 (store_user_signal_events): Return void, not int, since callers no
3474 longer care about the return value. All uses changed.
3476 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
3478 * w32gui.h (XParseGeometry): Do not declare.
3480 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
3482 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
3483 Ignore 'expected'. See Eli Zaretskii in
3484 <http://bugs.gnu.org/12471#8> (last line).
3486 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
3487 (XParseGeometry): Now static. Substitute extremal values for
3488 values that are out of range.
3490 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
3492 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
3494 * nsfns.m (XParseGeometry): Remove.
3495 (Fx_create_frame): Call x_set_offset to correctly interpret
3496 top_pos in geometry.
3498 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
3499 (Fx_parse_geometry): If there is a space in string, call
3500 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
3502 2012-09-17 Eli Zaretskii <eliz@gnu.org>
3504 * search.c (scan_buffer): Use character positions in calls to
3505 region_cache_forward and region_cache_backward, not byte
3506 positions. (Bug#12196)
3508 * w32term.c (w32_read_socket): Set pending_signals to 1, like
3509 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
3511 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
3512 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
3513 emacs_blocked_malloc, now deleted.
3515 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
3517 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
3518 The workaround was for improving performance on Solaris 2.4, but
3519 is getting in the way now. Emacs will still work if someone is
3520 still running Solaris 2.4 in a museum somewhere; Sun dropped
3521 support for Solaris 2.4 in 2003.
3522 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
3523 * process.c (create_process) [HAVE_WORKING_VFORK]:
3524 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
3525 since Emacs no longer uses vfork on that platform.
3527 2012-09-17 Glenn Morris <rgm@gnu.org>
3529 * emacs.c: Use COPYRIGHT.
3531 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
3533 Remove configure's --without-sync-input option (Bug#12450).
3534 When auditing signal-handling in preparation for cleaning it up,
3535 I found that SYNC_INPUT has race conditions and would be a real
3536 pain to fix. Since it's an undocumented and deprecated
3537 configure-time option, now seems like a good time to remove it.
3538 Also see <http://bugs.gnu.org/11080#16>.
3539 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
3540 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
3541 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
3542 (malloc_hysteresis):
3543 (check_depth) [XMALLOC_OVERRUN_CHECK]:
3544 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
3545 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
3546 (dont_register_blocks, bytes_used_when_reconsidered)
3547 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
3548 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
3549 [!SYSTEM_MALLOC && !SYNC_INPUT]:
3550 Remove. All uses removed.
3551 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
3552 implementation, one that depends on whether the new macro
3553 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
3555 * atimer.c (run_timers, handle_alarm_signal):
3556 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
3557 (handle_async_input, process_pending_signals)
3558 (handle_input_available_signal, init_keyboard):
3559 * nsterm.m (ns_read_socket):
3560 * process.c (wait_reading_process_output):
3561 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
3562 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
3564 * xterm.c (XTread_socket):
3566 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
3567 * eval.c (handling_signal): Remove. All uses removed.
3568 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
3569 All uses replaced with the SYNC_INPUT version.
3570 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
3572 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
3575 * font.c (Ffont_shape_gstring): Remove unused local.
3577 2012-09-16 Glenn Morris <rgm@gnu.org>
3579 * Makefile.in (clean): No longer run nextstep's clean.
3581 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
3583 (ns-app): Move here from ns.mk, and simplify.
3584 (clean): Simplify nextstep entry.
3585 * ns.mk: Remove file.
3587 2012-09-17 Kenichi Handa <handa@gnu.org>
3589 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
3590 not covert the last few charactes.
3592 2012-09-16 Kenichi Handa <handa@gnu.org>
3594 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
3595 here, but just check the validity of glyphs in the glyph-string.
3597 2012-09-16 Martin Rudalics <rudalics@gmx.at>
3599 * window.c (Fwindow_parameter, Fset_window_parameter):
3600 Accept any window as argument (Bug#12452).
3602 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
3604 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
3605 to ns_term_init to avoid memory leak.
3607 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
3608 explicit retain/release.
3609 (ns_term_init): Only allow one display. Initialize outerpool and
3612 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
3614 Port _setjmp fix to POSIXish hosts as well as Microsoft.
3615 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
3616 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
3617 the Microsoft problem in a different way, by altering ../nt/config.nt.
3619 2012-09-15 Eli Zaretskii <eliz@gnu.org>
3634 * w16select.c: Remove inclusion of setjmp.h, as it is now included
3635 by lisp.h. This completes removal of setjmp.h inclusion
3636 erroneously announced in the previous commit. (Bug#12446)
3638 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
3641 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
3642 not defined as a macro. The latter happens on MS-Windows.
3645 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
3647 Port better to POSIX hosts lacking _setjmp (Bug#12446).
3648 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
3649 Some instances of '#include <setjmp.h>' removed, if the
3650 only reason for the instance was because "lisp.h" was included.
3651 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
3652 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
3653 and _longjmp with the new symbols. Emacs already uses _setjmp if
3654 available, so this change affects only POSIXish hosts that have
3655 sigsetjmp but not _setjmp, such as some versions of Solaris and
3656 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
3657 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
3658 (png_load_body) [HAVE_PNG]:
3659 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
3660 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
3661 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
3662 since PNG requires jmp_buf. This is the only exception to the
3663 general rule that we now use sys_setjmp and sys_longjmp.
3664 This exception is OK since this code does not change the signal
3665 mask or longjmp out of a signal handler.
3667 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
3669 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
3670 Include "syssignal.h", for 'main_thread'.
3672 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
3674 Avoid out-of-range marker position (Bug#12426).
3675 * insdel.c (replace_range, replace_range_2):
3676 Adjust markers before overlays, as suggested by comments.
3677 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
3678 Remove redundant check before calling offset_intervals.
3680 2012-09-14 Martin Rudalics <rudalics@gmx.at>
3682 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
3683 current buffer (Bug#12387).
3685 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
3687 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
3689 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
3691 Use a more backwards-compatible timer format (Bug#12430).
3692 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
3693 vector element, not from the 4th, since PSECS is now at the end.
3694 (Fcurrent_idle_time): Doc fix.
3696 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
3698 Function to mark objects and remove killed buffers at once.
3699 * alloc.c (discard_killed_buffers): Rename to ...
3700 (mark_discard_killed buffers) ... new name. Add marking
3701 of remaining objects. Fix comment. Adjust users.
3702 (mark_object): Do not touch frame buffer lists here.
3703 * frame.c (delete_frame): Reset frame buffer lists here.
3705 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
3707 Better workaround for GNOME bug when --enable-gcc-warnings.
3708 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
3709 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
3710 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
3712 Simplify SIGIO usage (Bug#12408).
3713 The code that dealt with SIGIO was crufty and confusing, e.g., it
3714 played tricks like "#undef SIGIO" but these tricks were not used
3715 consistently. Simplify mostly by not #undeffing standard symbols,
3716 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
3717 or not as we please) rather than "defined SIGIO" (standard symbol
3718 that we probably shouldn't #undef).
3719 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
3720 Modules that need it can include it.
3721 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
3722 * dispextern.h (ignore_sigio): New decl.
3723 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
3724 unconditionally, since it's now a no-op if !USABLE_SIGIO.
3725 * emacs.c (shut_down_emacs):
3726 * keyboard.c (kbd_buffer_store_event_hold):
3727 Use ignore_sigio rather than invoking 'signal' directly.
3728 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
3730 (FIONREAD, SIGIO): Do not #undef.
3731 (tty_read_avail_input): Use #error rather than a syntax error.
3732 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
3733 for I_PIPE, used by SETUP_SLAVE_PTY.
3734 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
3735 * sysdep.c (croak): Remove; no longer needed. This bit of
3736 temporary code, with Fred N. Fish's comment that it's temporary,
3737 has been in Emacs since at least 1992!
3738 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
3739 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
3740 * syssignal.h (croak): Remove decl.
3741 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
3742 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
3743 now that we're termios-only.
3744 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
3745 * term.c (dissociate_if_controlling_tty): Use #error rather than
3748 Work around GCC and GNOME bugs when --enable-gcc-warnings.
3749 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
3750 to work around GNOME bug 683906.
3751 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
3752 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
3753 This works around GCC bug 54561.
3755 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
3757 More fixes for 'volatile' and setjmp/longjmp.
3758 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
3759 * image.c (struct png_load_context) [HAVE_PNG]: New type.
3760 (png_load_body) [HAVE_PNG]:
3761 (jpeg_load_body) [HAVE_JPEG]:
3762 New function, with most of the old parent function's body.
3763 (png_load) [HAVE_PNG]:
3764 (jpeg_load) [HAVE_JPEG]:
3765 Invoke the new function, to avoid longjmp munging our locals.
3766 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
3767 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
3768 longjmp is passed 2, as the C standard doesn't guarantee this.
3769 Instead, store the failure code into mgr->failure_code.
3771 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
3773 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
3774 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
3775 (syms_of_keyboard): Remove support for unread-command-char.
3777 2012-09-12 Eli Zaretskii <eliz@gnu.org>
3779 * w32proc.c (sys_kill): If PID is our process ID and the signal is
3780 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
3781 violation. (Bug#12426)
3783 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
3785 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
3787 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
3789 * eval.c: Add `inhibit-debugger'.
3790 (Qinhibit_debugger): New symbol.
3791 (call_debugger): Bind it instead of Qdebug_on_error.
3792 (maybe_call_debugger): Test Vinhibit_debugger.
3793 (syms_of_eval): Define inhibit-debugger.
3794 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
3795 (syms_of_xdisp): Remove inhibit-debug-on-message.
3797 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
3799 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
3800 If a nonvolatile local variable is written before a _longjmp to
3801 the frame containing the variable, and is read after the _longjmp,
3802 the value read is indeterminate. Some local variables of type
3803 'struct handler' and 'struct catchtag' are used in this way, so
3804 mark each of their slots as volatile if the slot can be set before
3805 _longjmp and read afterwards.
3806 * lisp.h (struct handler): var and chosen_clause are now volatile.
3807 (struct catchtag): val, next, and pdlcount are now volatile.
3809 * bidi.c (bidi_push_it, bidi_pop_it):
3810 * fns.c (copy_hash_table):
3811 * image.c (define_image_type):
3812 * keyboard.c (kbd_buffer_store_event_hold):
3813 * process.c (Fprocess_send_eof):
3814 * xfaces.c (x_create_gc) [HAVE_NS]:
3815 * xgselect.c (xg_select):
3816 Prefer assignment to memcpy when either will do.
3818 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
3819 Use pointer-to-a-pointer to simplify and avoid a NILP check each
3820 time an item is removed. No need to mark this function 'inline';
3821 the compiler knows better than we do.
3823 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
3825 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
3826 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
3827 to change_frame_size (Bug#12388).
3828 (windowDidResize:): Pass YES to updateFrameSize.
3830 * nsterm.h: Add delay parameter to updateFrameSize.
3832 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
3834 Discard killed buffers from deleted window and frame objects.
3835 This reduces an amount of references to killed buffers and
3836 helps GC to reclaim them faster.
3837 * alloc.c (discard_killed_buffers): New function.
3838 (mark_object): Use it for deleted windows and frames.
3839 (mark_object): If symbol's value is set up for a killed buffer
3840 or deleted frame, restore its global binding.
3841 * data.c (swap_in_global_binding): Add GC notice.
3842 (swap_in_symval_forwarding): Use convenient set_blv_where.
3843 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
3844 * window.h: ... to here.
3846 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
3848 Convenient macro to check whether the buffer is live.
3849 * buffer.h (BUFFER_LIVE_P): New macro.
3850 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
3851 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
3853 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3855 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
3856 composition cases (Bug#12364).
3858 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
3859 overhang of succeeding glyphs overlapping box cursor.
3861 * w32term.c (x_draw_glyph_string): Likewise.
3863 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
3865 Simplify, document, and port floating-point (Bug#12381).
3866 The porting part of this patch fixes bugs on non-IEEE platforms
3867 with frexp, ldexp, logb.
3868 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
3870 * floatfns.c: Simplify discussion of functions that Emacs doesn't
3871 support, by removing commented-out code and briefly listing the
3872 C89 functions excluded. The commented-out stuff was confusing
3873 maintenance, e.g., we thought we needed cbrt but it was commented out.
3874 (logb): Remove decl; no longer needed.
3875 (isfinite): New macro, if not already supplied.
3876 (isnan): Don't replace any existing macro.
3877 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
3878 are present on all C89 platforms.
3879 (Ffrexp): Do not special-case zero, as frexp does the right thing
3881 (Flogb): Do not use logb, as it doesn't have the desired meaning
3882 on hosts that use non-base-2 floating point. Instead, stick with
3883 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
3884 frexp, to avoid getting an unspecified result.
3886 * xdisp.c (Qinhibit_debug_on_message): Now static.
3888 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
3890 * nsterm.m (ns_update_begin): Set clip path to whole view by using
3891 NSBezierPath (Bug#12131).
3893 2012-09-10 Chong Yidong <cyd@gnu.org>
3895 * fns.c (Fdelq, Fdelete): Doc fix.
3897 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
3899 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
3900 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
3902 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
3904 * lisp.h (make_lisp_ptr): New macro to replace XSET.
3905 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
3908 2012-09-09 Eli Zaretskii <eliz@gnu.org>
3910 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
3911 left fringe if the window has a left margin. This avoids leaving
3912 traces of the cursor because its leftmost pixel is not drawn over.
3914 * dispnew.c (update_window_line): When the left margin area of a
3915 screen line is updated, set the redraw_fringe_bitmaps_p flag of
3916 that screen line. (Bug#12277)
3918 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
3920 Assume C89 or later for math functions (Bug#12381).
3921 This simplifies the code, and makes it a bit smaller and faster,
3922 and (most important) makes it easier to clean up signal handling
3923 since we can stop worring about floating-point exceptions in
3924 library code. That was a problem before C89, but the problem
3925 went away many years ago on all practical Emacs targets.
3926 * data.c, image.c, lread.c, print.c:
3927 Don't include <math.h>; no longer needed.
3928 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
3929 might be autoconfigured, as that never happens.
3931 * doprnt.c (DBL_MAX_10_EXP):
3932 * print.c (DBL_DIG):
3933 Remove. C89 or later always defines these.
3934 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
3935 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
3936 (arith_error, domain_error, domain_error2):
3937 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
3938 no longer needed -- we simply return what C returns. All uses removed.
3939 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
3941 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
3942 Remove. All uses expanded, as these macros are no longer used
3943 more than once and are now more trouble than they're worth.
3944 (Ftan): Use tan, not sin / cos.
3945 (Flogb): Assume C89 frexp.
3946 (fmod_float): Assume C89 fmod.
3947 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
3948 (init_floatfns): Remove. All uses removed.
3950 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
3952 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
3953 compositeToPoint for OSX < 10.6 (Bug#12390).
3955 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
3957 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
3958 This produces more-accurate results.
3960 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
3962 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
3963 changes (Bug#12088).
3965 2012-09-08 Chong Yidong <cyd@gnu.org>
3967 * syntax.c (Fstring_to_syntax): Doc fix.
3969 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
3971 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
3972 in the internal border.
3973 (x_set_window_size): Remove static variables and their usage.
3974 (ns_redraw_scroll_bars): Fix NSTRACE arg.
3975 (ns_after_update_window_line, ns_draw_fringe_bitmap):
3976 Remove fringe/internal border adjustment (Bug#11052).
3977 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
3978 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
3979 (ns_fix_rect_ibw): Remove.
3980 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
3981 (ns_dumpglyphs_box_or_relief): Ditto.
3982 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
3984 (ns_dumpglyphs_image): Ditto.
3985 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
3987 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
3988 their usage. Add fringe_extended_p and its use as in other terms.
3989 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
3990 scroll bar was removed.
3991 (updateFrameSize): New function.
3992 (windowDidResize): Move code to updateFrameSize and call it.
3994 * nsterm.h (EmacsView): Add updateFrameSize.
3996 2012-09-07 Chong Yidong <cyd@gnu.org>
3998 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
4000 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
4002 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
4004 More signal-handler cleanup (Bug#12327).
4005 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
4006 Problem introduced when merging patches. Noted by Eli Zaretskii in
4007 <http://bugs.gnu.org/12327#67>.
4008 * floatfns.c: Comment fix.
4009 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
4010 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
4011 and anyway the declaration is harmless even if SIGDANGER is not defined.
4012 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
4013 defined BROKEN_FIONREAD). systty.h formerly did this, but other
4014 source files not surprisingly expected syssignal.h to define, or
4015 not define, SIGIO, and it's cleaner to do it that way, for consistency.
4016 Include <sys/ioctl.h>, for FIONREAD.
4017 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
4018 This eliminates a problem whereby other files mysteriously had
4019 to include "syssignal.h" before including "systty.h" if they
4020 wanted to use "#ifdef SIGIO".
4022 2012-09-07 Eli Zaretskii <eliz@gnu.org>
4024 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
4026 * w32.c (sigemptyset): Empty the set.
4027 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
4029 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
4031 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
4033 * alloc.c (mark_buffer): Revert unsafe marking optimization.
4034 (mark_object): Likewise for frame objects.
4036 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
4038 * syssignal.h (handle_on_main_thread): Always declare,
4039 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
4040 This ports to platforms without HAVE_PTHREAD.
4042 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
4044 Signal-handler cleanup (Bug#12327).
4045 Emacs's signal handlers were written in the old 4.2BSD style with
4046 sigblock and sigmask and so forth, and this led to some
4047 inefficiencies and confusion. Rewrite these to use
4048 pthread_sigmask etc. without copying signal sets around. Also,
4049 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
4050 'signal', and instead use functions that do not attempt to take
4051 over the system name space. This patch causes Emacs's text
4052 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
4053 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
4054 Do not include <signal.h> or "syssignal.h", as these
4055 modules do not use signals.
4056 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
4057 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
4058 Do not include <signal.h>, as "syssignal.h" does that for us now.
4059 * atimer.c (sigmask_atimers): New function.
4060 (block_atimers, unblock_atimers): New functions,
4061 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
4063 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
4064 no longer needed here.
4065 * emacs.c (main): Inspect existing signal handler with sigaction,
4066 so that there's no need to block and unblock SIGHUP.
4067 * sysdep.c (struct save_signal): New member 'action', replacing
4068 old member 'handler'.
4069 (save_signal_handlers, restore_signal_handlers):
4070 Use sigaction instead of 'signal' to save and restore.
4071 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
4072 New function. All users of 'signal' modified to use set_sighandler
4073 if they're writeonly, and to use sys_signal if they're read+write.
4074 (emacs_sigaction_init, forwarded_signal): New functions.
4075 (sys_signal): Remove. All uses replaced by calls to sigaction
4076 and emacs_sigaction_init, or by direct calls to 'signal'.
4077 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
4078 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
4079 all uses replaced by pthread_sigmask etc. calls.
4080 * syssignal.h: Include <signal.h>.
4081 (emacs_sigaction_init, forwarded_signal): New decls.
4082 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
4083 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
4084 (sigmask, sys_sigmask): Remove; no longer needed.
4085 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
4086 (sigblock, sigunblock, sigfree):
4087 (sigsetmask) [!defined sigsetmask]:
4088 Remove. All uses replaced by pthread_sigmask.
4089 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
4090 no longer need to be replaced, and its typical old uses
4091 are now done via emacs_sigaction_init and sigaction.
4092 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
4093 (sys_sigdel): Remove; unused.
4094 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
4096 2012-09-06 Eli Zaretskii <eliz@gnu.org>
4098 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
4099 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
4101 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
4103 Explicitly mark buffer_defaults and buffer_local_symbols.
4104 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
4105 mark_local_symbols here.
4106 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
4107 since special buffers aren't marked here any more.
4108 (allocate_buffer): Chain new buffer with all_buffers here...
4109 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
4111 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
4112 (syms_of_buffer): Remove staticpro of the above.
4113 (init_buffer_once): Set names for buffer_defaults and
4114 buffer_local_symbols.
4116 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
4118 Use bool for booleans in font-related modules.
4119 * font.c (font_intern_prop, font_style_to_value)
4120 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
4121 (generate_otf_features, font_check_otf_features, font_check_otf)
4122 (font_match_p, font_list_entities, font_at):
4123 * fontset.c (fontset_id_valid_p, reorder_font_vector
4124 (fontset_find_font, Fset_fontset_font)
4125 (face_suitable_for_char_p) [0]:
4126 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
4127 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
4128 (m17n_flt_initialized, ftfont_shape_by_flt):
4129 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
4130 * nsfont.m (nsfont_draw):
4131 * w32font.c (w32font_draw):
4132 * w32term.c (x_draw_glyphless_glyph_string_foreground):
4133 Use bool for booleans.
4134 * font.h: Adjust to above API changes.
4135 (struct font, struct font_driver, struct font_driver_list):
4136 Use bool for booleans.
4137 (struct font): Remove useless member encoding_type.
4139 * fontset.c, xftfont.c: Omit unnecessary static decls.
4141 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
4143 * alloc.c (mark_object): Revert window marking code
4144 since it's unsafe for the Fset_window_configuration.
4146 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
4148 Fix race conditions with signal handlers and errno (Bug#12327).
4149 Be more systematic about preserving errno whenever a signal
4150 handler returns, even if it's not in the main thread. Do this by
4151 renaming signal handlers to distinguish between signal delivery
4152 and signal handling. All uses changed.
4153 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
4154 * data.c (deliver_arith_signal): Rename from arith_error.
4155 * dispnew.c (deliver_window_change_signal): Rename from
4156 window_change_signal.
4157 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
4158 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
4159 * keyboard.c (deliver_input_available_signal): Rename from
4160 input_available_signal.
4161 (deliver_user_signal): Rename from handle_user_signal.
4162 (deliver_interrupt_signal): Rename from interrupt_signal.
4163 * process.c (deliver_pipe_signal): Rename from send_process_trap.
4164 (deliver_child_signal): Rename from sigchld_handler.
4165 * atimer.c (handle_alarm_signal):
4166 * data.c (handle_arith_signal):
4167 * dispnew.c (handle_window_change_signal):
4168 * emacs.c (handle_fatal_signal, handle_danger_signal):
4169 * keyboard.c (handle_input_available_signal):
4170 * keyboard.c (handle_user_signal, handle_interrupt_signal):
4171 * process.c (handle_pipe_signal, handle_child_signal):
4172 New functions, with the actual signal-handling code taken from the
4173 original respective signal handlers, sans the sporadic attempts to
4174 preserve errno, since that's now done by handle_on_main_thread.
4175 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
4176 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
4177 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4179 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4180 Move initialization of main_thread to sysdep.c's init_signals.
4181 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
4182 our usage, and simplifies the mainline code.
4183 (record_child_status_change): New static function, as a helper
4184 for handle_child_signal, and with most of the old child handler's
4186 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
4187 (handle_child_signal): Use the above.
4188 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4189 Moved here from emacs.c.
4190 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
4191 code moved here from emacs.c's main function.
4192 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
4193 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
4194 This lets callers save and restore errno properly.
4196 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4198 Remove redundant or unused things here and there.
4199 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
4200 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
4201 * editfns.c (Fcompare_buffer_substrings): Likewise.
4202 * frame.h (struct terminal, struct font_driver_list):
4203 Remove redundant declarations.
4204 * window.h (Qleft, Qright): Likewise.
4206 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4208 Do not mark objects from deleted buffers, windows and frames.
4209 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
4210 (mark_object): Likewise for windows and frames.
4212 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4214 * alloc.c (valid_lisp_object_p): Treat killed buffers,
4215 buffer_defaults and buffer_local_symbols as valid objects.
4216 Return special value to denote them.
4218 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
4220 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
4221 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
4222 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
4223 (file_name_absolute_p, Fsubstitute_in_file_name):
4224 (check_executable, check_writable, Ffile_accessible_directory_p)
4225 (Fset_file_selinux_context, Fdefault_file_modes)
4226 (Finsert_file_contents, choose_write_coding_system)
4227 (Fwrite_region, build_annotations, a_write, e_write)
4229 * filelock.c (boot_time_initialized, get_boot_time)
4230 (get_boot_time_1, lock_file_1, within_one_second):
4231 * floatfns.c (in_float):
4232 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
4233 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
4234 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
4235 * lisp.h (struct Lisp_Hash_Table.cmpfn):
4236 * window.c (compare_window_configurations):
4237 Use bool for booleans.
4238 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
4239 (Fdefault_file_modes): Now mode_t, not int, for modes.
4240 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
4241 (internal_delete_file): Now returns void, not a (boolean) int,
4242 since nobody was looking at the return value.
4243 * lisp.h, window.h: Adjust to above API changes.
4245 * xdisp.c (set_message): Simplify and reindent last change.
4247 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
4249 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
4251 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
4253 * eval.c (call_debugger): Make the function non-static so that we
4254 can call it from set_message.
4256 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
4257 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
4259 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
4261 Give more-useful info on a fatal error (Bug#12328).
4262 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
4263 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
4264 of doing the work ourselves.
4265 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
4266 do most of the work.
4267 (fatal_error_backtrace): New function, taken from the guts
4268 of the old fatal_error_signal, but with a new option to output
4270 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
4271 info about the signal than just its number.
4272 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
4273 * sysdep.c: Include <execinfo.h>
4274 (emacs_backtrace): New function, taken partly from the previous
4275 code of the 'die' function.
4276 (emacs_abort): Call fatal_error_backtrace rather than abort.
4278 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
4280 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
4281 eager (load-time) macro-expansion.
4282 * lisp.mk (lisp): Add macroexp.
4284 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
4286 Simplify redefinition of 'abort' (Bug#12316).
4287 Do not try to redefine the 'abort' function. Instead, redo
4288 the code so that it calls 'emacs_abort' rather than 'abort'.
4289 This removes the need for the NO_ABORT configure-time macro
4290 and makes it easier to change the abort code to do a backtrace.
4291 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
4292 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
4293 Remove; sysdep.c's emacs_abort now takes its place.
4294 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
4295 'abort' changed to use 'emacs_abort'.
4296 * msdos.c (dos_abort) [defined abort]: Remove; not used.
4297 (abort) [!defined abort]: Rename to ...
4298 (emacs_abort): ... new name.
4299 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
4300 the place of the old 'abort' in emacs.c.
4301 * w32.c, w32fns.c (abort): Do not #undef.
4302 * w32.c (emacs_abort): Rename from w32_abort.
4304 2012-09-04 Eli Zaretskii <eliz@gnu.org>
4306 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
4307 offsets[j].dv, since the y axis of the screen coordinates points
4308 down, while the y axis of the font definition coordinates points
4309 up. This fixes display of Arabic diacritics such as KASRA and
4310 KASRATAN. (Bug#11860)
4312 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
4314 Be more systematic about _setjmp vs setjmp.
4315 * alloc.c (test_setjmp, mark_stack):
4316 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
4317 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
4318 (png_load, my_error_exit, jpeg_load):
4319 * process.c (send_process_trap, send_process):
4320 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
4321 The underscored versions are up to 30x faster on some hosts.
4322 Formerly, the code used setjmp+longjmp sometimes and
4323 _setjmp+_longjmp at other times, with no particular reason to
4324 prefer setjmp+longjmp.
4326 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
4328 Fix minor problem found by static checking.
4329 * buffer.c (Fdelete_all_overlays): Return nil.
4331 2012-09-03 Martin Rudalics <rudalics@gmx.at>
4333 * buffer.c (Fdelete_all_overlays): New function.
4335 2012-09-03 Chong Yidong <cyd@gnu.org>
4337 * gtkutil.c: Add extern decl for Qxft.
4339 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
4341 * emacs.c, eval.c: Use bool for boolean.
4342 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
4343 (malloc_using_checking) [DOUG_LEA_MALLOC]:
4344 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
4345 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
4346 (main, decode_env_path, Fdaemon_initialized):
4347 * eval.c (call_debugger, Finteractive_p, interactive_p):
4348 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
4349 (maybe_call_debugger, Fbacktrace):
4350 * process.c (read_process_output, exec_sentinel):
4351 Use bool for booleans.
4352 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
4353 All callers changed.
4354 * eval.c (interactive_p): Omit always-true boolean argument
4355 EXCLUDE_SUBRS_P. All callers changed.
4356 * dispextern.h, lisp.h: Reflect above API changes.
4357 * firstfile.c (dummy): Use the address of 'main', whose signature
4358 won't change, instead of the address of 'initialize', whose
4359 signature just changed from int to bool.
4360 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
4361 * msdos.c (fatal_error_in_progress): ... from here.
4362 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
4364 (redisplay_internal, unwind_redisplay): Simply clear
4365 REDISPLAYING_P when unwinding, instead of saving its previous,
4366 always-false value and then restoring it.
4368 Clean up some extern decls.
4369 Mostly, this hoists extern decls out of .c files and into .h files.
4370 That way, we're more likely to catch errors if the interfaces change.
4371 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
4372 declare xg_mark_data.
4373 * dispextern.h (x_frame_parm_handlers):
4375 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
4376 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
4377 (Qultra_bold, Qoblique, Qitalic):
4378 Move extern decl here from .c file.
4379 * alloc.c (xg_mark_data) [USE_GTK]:
4381 * eval.c (Qlexical_binding):
4382 * fns.c (time) [!HAVE_UNISTD_H]:

4391 * xfont.c (x_clear_errors):
4392 * xterm.c (x_frame_parm_handlers):
4393 Remove now-redundant extern decls.
4394 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
4395 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
4397 * xfaces.c: Remove unnecessary static decls.
4398 * xterm.c (updating_frame): Remove decl of nonexistent object.
4400 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
4401 when building globals.h, as the objects that are not built on
4402 this host are not needed to compile C files on this host.
4404 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
4406 * gtkutil.h: Remove prototype for x_wm_set_size_hint.
4408 * frame.h: Add missing prototype for x_wm_set_size_hint.
4410 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>

4444 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
4446 * makefile.w32-in (CCL_H, W32FONT_H): New macros.
4447 (ATIMER_H, FONT_H, $(BLD)/alloc.$(O), $(BLD)/callproc.$(O))

4452 ($(BLD)/w32font.$(O), $(BLD)/w32uniscribe.$(O)): Update dependencies.
4454 2012-09-01 Eli Zaretskii <eliz@gnu.org>
4456 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
4457 more than one grapheme cluster passed to the shaper: compute the
4458 offset adjustment values separately for each cluster. (Bug#11860)
4460 * image.c: Restore mistakenly removed inclusion of w32.h. Without
4461 it, GCC doesn't see prototypes of w32_delayed_load, and complains
4462 about implicit conversions from integer to pointer.
4464 2012-09-01 Daniel Colascione <dancol@dancol.org>
4466 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
4467 system used too early.
4469 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
4471 Better seed support for (random).
4472 * emacs.c (main): Call init_random.
4473 * fns.c (Frandom): Set the seed from a string argument, if given.
4474 Remove long-obsolete Gentzel cruft.
4475 * lisp.h, sysdep.c (seed_random): Now takes address and size, not long.
4476 (init_random): New function.
4478 2012-09-01 Daniel Colascione <dancol@dancol.org>

4481 Remove x_set_frame_alpha, x_bitmap_icon, x_make_frame_visible,
4482 x_make_frame_invisible, x_iconify_frame, x_free_frame_resources,
4483 x_wm_set_size_hint, x_query_colors, x_real_positions,
4484 x_set_menu_bar_lines, x_char_width, x_char_height, x_sync,
4485 x_set_tool_bar_lines, x_activate_menubar, and free_frame_menubar,
4486 all of which have been moved to common code.
4488 * xfaces.c: Include TERM_HEADER instead of listing all possible
4489 window-system headers.
4491 * w32xfns.c (x_sync): Correct definition of x_sync (a no-op here)
4494 * w32term.h (FRAME_X_WINDOW): Use FRAME_W32_WINDOW instead of
4495 directly accessing frame internals.
4497 * w32font.h: Include font.h. Define syms_of_w32font and
4500 * process.c: Include TERM_HEADER instead of listing all possible
4501 window-system headers.
4503 * nsterm.h: Remove declarations now in frame.h.
4504 Define FRAME_X_SCREEN, FRAME_X_VISUAL.
4506 * menu.c: Include TERM_HEADER instead of listing all possible
4507 window-system headers.
4509 * keyboard.h: Declare ignore_mouse_drag_p whenever we have a
4512 * keyboard.c: Include TERM_HEADER instead of listing all possible
4513 window-system headers.
4515 * image.c: Include TERM_HEADER instead of listing all possible
4516 window-system headers. Declare Vlibrary_cache when compiling for
4519 * gtkutil.h (xg_list_node_): Include xterm.h to pick up needed
4520 window system declarations.
4522 * frame.h: Move common functions here: set_frame_menubar,
4523 x_set_window_size, x_sync, x_get_focus_frame,
4524 x_set_mouse_position, x_set_mouse_pixel_position,
4525 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

4545 * Makefile.in: Define WINDOW_SYSTEM_OBJ to hold objects needed for
4546 the current window system; include in list of objects to link into
4549 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
4551 Remove mark_ttys function and fix tty_display_info initialization.
4552 * lisp.h (mark_ttys): Remove prototype.
4553 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
4554 to mark_ttys because all possible values of 'top_frame' slot are
4555 the frames which are reachable from Vframe_list.
4556 * term.c (mark_ttys): Remove.
4557 (init_tty): Safely initialize 'top_frame' slot with Qnil.
4559 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
4561 Change struct frame bitfields from unsigned char to unsigned.
4562 * frame.h (struct frame): Change type of 'display_preempted',

4568 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
4570 Remove unused member of struct x_output and struct w32_output.
4571 * xterm.h (struct x_output): Remove unused field 'needs_exposure'.
4572 * w32term.h (struct w32_output): Likewise.
4574 2012-08-30 Jan Djärv <jan.h.d@swipnet.se>
4576 * gtkutil.c (x_wm_set_size_hint): Use 1 col for base_width so it
4577 does not become zero (Bug#12234).
4579 2012-08-30 Paul Eggert <eggert@cs.ucla.edu>
4581 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
4582 for GCC 4.7.1 x86-64.
4584 2012-08-30 Glenn Morris <rgm@gnu.org>
4586 * lread.c (init_lread): For out-of-tree builds, only add the
4587 source directory's site-lisp dir to the load-path if it exists,
4588 consistent with in-tree builds. (Bug#12302)
4590 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>
4592 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize
4593 button_values to NULL. Call setStykeMask so dialogs get a close button.
4594 (windowShouldClose:): Set window_closed.
4595 (dealloc): New member, free button_values.
4596 (process_dialog:): Make member function. Remove window argument,
4597 replace window with self. Count buttons and allocate and store values
4599 (addButton:value:row:): value is int with the name tag. Call setTag
4600 with tag. Remove return self, declare return value as void.
4601 (addString:row:): Remove return self, declare return value as void.
4602 (addSplit): Remove return self, declare return value as void.
4603 (clicked:): Remove return self, declare return value as void.
4604 Set dialog_return to button_values[seltag]. Code formatting change.
4605 (initFromContents:isQuestion:): Adjust call to process_dialog.
4606 Code formatting change.
4607 (timeout_handler:): Set timer_fired to YES.
4608 (runDialogAt:): Set timer_fired to NO.
4609 Handle click on close button as quit.
4611 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
4612 Add window_closed and button_values. Add void as return value for
4613 add(Button|String|Split). addButton takes int instead of Lisp_Object.
4614 Add process_dialog as new member.
4616 2012-08-28 Eli Zaretskii <eliz@gnu.org>
4618 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it
4619 is not one of the heaps we manage. (Bug#12242)
4621 2012-08-28 Glenn Morris <rgm@gnu.org>
4623 * eval.c (Fcalled_interactively_p): Doc fix. (Bug#11747)
4625 2012-08-28 Martin Rudalics <rudalics@gmx.at>
4627 * window.c (Fset_window_configuration): Remove handling of
4628 auto-buffer-name window parameter. Install revision of reverted
4631 2012-08-28 Dmitry Antipov <dmantipov@yandex.ru>
4633 Do not allow to set major mode for a dead buffer.
4634 * buffer.c (Fset_buffer_major_mode): Signal an error
4635 if the buffer is dead.
4636 (Fother_buffer, other_buffer_safely): Remove redundant
4639 2012-08-28 Dmitry Antipov <dmantipov@yandex.ru>
4641 Always use set_buffer_if_live to restore original buffer at unwind.
4642 * buffer.h (record_unwind_current_buffer): New function.
4643 * bytecode.c, dispnew.c, editfns.c, fileio.c, fns.c, insdel.c:
4644 * keyboard.c, keymap.c, minibuf.c, print.c, process.c, textprop.c:
4645 * undo.c, window.c: Adjust users.
4646 * buffer.c (set_buffer_if_live): Fix comment.
4648 2012-08-28 Dmitry Antipov <dmantipov@yandex.ru>
4650 Fix usage of set_buffer_internal.
4651 * buffer.h (set_buffer_internal): Make it BUFFER_INLINE.
4652 * buffer.c (set_buffer_if_live): Use set_buffer_internal.
4653 * coding.c (decode_coding): Omit redundant test.
4654 * fileio.c (decide_coding_unwind): Likewise.
4655 * fns.c (secure_hash): Likewise.
4656 * insdel.c (modify_region): Likewise.
4657 * keyboard.c (command_loop_1): Likewise.
4658 * print.c (PRINTFINISH): Likewise.
4659 * xdisp.c (run_window_scroll_functions): Use set_buffer_internal.
4661 2012-08-27 Paul Eggert <eggert@cs.ucla.edu>

4680 Use bool for boolean.
4681 (clear_glyph_matrix_rows): Rename from enable_glyph_matrix_rows,
4682 and remove last int (actually boolean) argument, which was always 0.
4683 All callers changed.
4684 * dispextern.h, frame.h, lisp.h: Reflect above API changes.
4685 * dispextern.h (struct composition_it): Use bool for boolean.
4686 (struct glyph_matrix): Don't assume buffer sizes can fit in 'int'.
4687 (struct bidi_it): Use unsigned:1, not int, for boolean prev_was_pdf.
4688 * dired.c (file_name_completion):
4689 Use bool for boolean. (This was missed in an earlier change.)
4691 2012-08-27 Martin Rudalics <rudalics@gmx.at>
4693 * window.c (Fset_window_configuration): Revert first part of
4696 2012-08-27 Jan Djärv <jan.h.d@swipnet.se>
4698 * nsterm.h (NSPanel): New class variable dialog_return.
4700 * nsmenu.m (initWithContentRect:styleMask:backing:defer:):
4701 Initialize dialog_return.
4702 (windowShouldClose:): Use stop instead of stopModalWithCode.
4703 (clicked:): Ditto, and also set dialog_return (Bug#12258).
4704 (timeout_handler:): Use stop instead of abortModal. Send a dummy
4706 (runDialogAt:): Make ret Lisp_Object. Set it from dialog_return when

4721 Use bool for booleans.
4722 * dired.c (file_name_completion):
4723 * process.h (fd_callback):
4724 Omit int (actually boolean) argument. It wasn't being used.
4726 * composite.h, lisp.h: Reflect above API changes.

4750 * fileio.c (Finsert_file_contents):
4751 Use bool for booleans.
4752 * coding.h, lisp.h: Reflect above API changes.
4753 * coding.c: Remove unnecessary static function decls.
4754 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
4755 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
4756 not a boolean 'int', since callers never look at the return value.
4757 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
4758 * coding.h (decoding_buffer_size, encoding_buffer_size)
4759 (emacs_mule_string_char): Remove unused extern decls.
4760 (struct iso_2022_spec, struct coding_system):
4761 Use 'unsigned int : 1' for boolean fields, since there's more than one.
4762 (struct emacs_mule_spec): Remove unused field 'full_support'.
4763 All initializations removed.
4764 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
4766 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
4768 Fix spare memory change (Bug#12286).
4769 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
4770 (valid_lisp_object_p): Likewise.
4772 2012-08-27 Martin Rudalics <rudalics@gmx.at>
4774 * window.c (Fset_window_configuration): Record any window's old
4775 buffer if it's replaced (see Bug#8789). If the new current
4776 buffer doesn't appear in the selected window, go to its old
4779 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
4781 Special MEM_TYPE_SPARE to denote reserved memory.
4782 * alloc.c (enum mem_type): New memory type.
4783 (refill_memory_reserve): Use new type for spare memory.
4784 This prevents live_cons_p and live_string_p from incorrect
4785 detection of uninitialized objects from spare memory as live.
4787 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
4790 * Makefile.in (.PHONY): versioclean -> versionclean.
4792 Remove unused external symbols.
4793 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
4794 * window.c (Qwindow_valid_p, decode_valid_window):
4795 Now static, not extern.
4796 * data.c (Qinterval): Remove; unused.
4797 (syms_of_data): Do not define 'interval'.
4798 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
4799 * window.h (decode_valid_window):
4802 * character.c, charset.c, chartab.c: Use bool for booleans.

4812 (char_table_set_range, optimize_sub_char_table)
4813 (map_sub_char_table):
4814 Use bool for boolean.
4815 * character.c (str_to_unibyte): Omit last boolean argument; it was
4816 always 0. All callers changed.
4817 * character.h, charset.h: Adjust to match previous changes.
4818 * character.h (char_printable_p): Remove decl of nonexistent function.
4819 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
4820 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
4821 are all boolean, so make them single-bit bitfields.
4823 * lisp.h (ASET): Remove attempt to detect side effects.
4824 It was meant to be temporary and it often doesn't work,
4825 because when IDX has side effects the behavior of IDX==IDX
4826 is undefined. See Stefan Monnier in
4827 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
4829 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
4831 * lisp.h (functionp): New function (extracted from Ffunctionp).
4832 (FUNCTIONP): Use it.
4833 * eval.c (Ffunctionp): Use it.
4835 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
4837 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
4838 as that's faster and simpler than static storage. Don't bother
4839 with the g_main_context_query overhead if g_main_context_pending
4840 says no events are pending.
4841 (gfds, gfds_size): Remove these static vars.
4842 (xgselect_initialize): Remove; no longer needed.
4843 All uses and decls removed.
4845 * emacs.c (fatal_error_signal_hook): Remove.
4846 All uses removed. This leftover from old code was always 0.
4848 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
4849 * casefiddle.c (casify_object, casify_region):
4850 * casetab.c (set_case_table):
4851 * category.c, category.h (word_boundary_p):
4852 * category.h (CHAR_HAS_CATEGORY):
4853 Use bool for booleans, instead of int.
4855 2012-08-25 Eli Zaretskii <eliz@gnu.org>
4857 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
4859 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
4861 On assertion failure, print backtrace if available.
4862 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
4863 (die) [ENABLE_CHECKING]: Print a backtrace if available.
4864 * Makefile.in (LIB_EXECINFO): New macro.
4867 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
4868 * bytecode.c (exec_byte_code):
4869 * callint.c (check_mark, Fcall_interactively):
4870 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
4871 (getenv_internal, sync_process_alive, call_process_exited):
4872 * lisp.h (USE_SAFE_ALLOCA):
4873 Use bool for booleans, instead of int.
4874 * lisp.h, process.h: Adjust prototypes to match above changes.
4875 * callint.c (Fcall_interactively): Don't assume the mark's
4876 offset fits in 'int'.
4878 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
4880 * buffer.c, buffer.h: Use bool for boolean.
4881 * buffer.c (reset_buffer_local_variables)

4887 (mmap_enlarge, mmap_set_vars):
4888 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
4889 Use bool for booleans, instead of int.
4890 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
4891 since the 1-or-0 return value is always ignored anyway.
4892 (mmap_initialized_p):
4893 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
4894 * buffer.h, lisp.h: Adjust prototypes to match above changes.
4896 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
4898 * bidi.c: Use bool for boolean.
4899 This is a bit more readable, and makes the text segment of bidi.o
4900 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
4901 Presumably it's faster too.
4902 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):

4907 (bidi_explicit_dir_char, bidi_level_of_next_char)
4908 (bidi_find_other_level_edge, bidi_move_to_visually_next):
4909 Use bool for booleans, instead of int.
4910 * dispextern.h (bidi_init_it, bidi_paragraph_init)
4911 (bidi_unshelve_cache): Adjust decls to match code.
4913 2012-08-23 Martin Rudalics <rudalics@gmx.at>
4915 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
4918 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
4920 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
4921 * atimer.h: Include <stdbool.h>.
4923 2012-08-22 Dan Nicolaescu <dann@gnu.org>
4925 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
4926 compile time tests instead of run time tests on systems that do
4928 (FRAME_MAC_P): Remove leftover from deleted code.
4929 * frame.c (syms_of_frame): Remove leftover from deleted code.
4931 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
4933 * nsterm.m (insertText:): Don't clear modifiers if code is space.
4935 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
4937 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
4938 Otherwise, the compiler complains about (A?B:C) where B is void
4939 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
4940 (fontset_add): Return void, for FONTSET_ADD.
4942 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
4944 * alloc.c: Use bool for booleans.
4945 (gc_in_progress, abort_on_gc)
4946 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
4947 (dont_register_blocks) [GC_MALLOC_CHECK]:
4948 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.

4951 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
4952 (mark_stack, valid_pointer_p, make_pure_string)
4953 (Fgarbage_collect, survives_gc_p, gc_sweep):
4954 Use bool for booleans, instead of int.
4955 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
4956 Remove unused local.
4957 * alloc.c (PURE_POINTER_P):
4958 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
4959 * editfns.c (Fformat):
4960 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
4962 * fns.c (sweep_weak_table):
4963 * lisp.h (suppress_checking, push_message, survives_gc_p)
4964 (make_pure_string, gc_in_progress, abort_on_gc):
4965 * lread.c (readchar, read1):
4966 * print.c (Fprin1_to_string):
4967 * xdisp.c (push_message):
4968 Use bool for booleans affected directly or indirectly by
4971 Make recently-introduced setters macros.
4972 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
4973 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
4974 (set_fontset_default, set_fontset_fallback): Rename from their
4975 upper-case counterparts, and make them functions rather than macros.
4976 This is more consistent with the other recently-introduced setters.
4977 These don't need to be inline, since they're local.
4979 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
4981 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
4982 the loop (Bug#12247).
4984 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
4986 * lisp.h (vcopy): Use memcpy rather than our own loop.
4987 This fixes a performance regression introduced by the recent
4988 addition of vcopy. This means 'vcopy' will need to be modified
4989 for a copying collector, but that's OK. Also, tighten the
4990 checking in the assertion.
4992 2012-08-21 Eli Zaretskii <eliz@gnu.org>
4994 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
4995 components for RTL text (Bug#11860). Adjust X-OFFSET of each
4996 non-base glyph for the width of the base character, according to
4997 what x_draw_composite_glyph_string_foreground expects.
4998 Generate WADJUST value according to composition_gstring_width's

5086 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>

5089 as gnulib does this if the system doesn't.
5090 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:

5961 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
5962 * w32.c (init_environment): Change the default values of many
5963 environment variables in dflt_envvars[] to NULL, to avoid pushing
5964 them into environment when they were not already defined.
5965 Remove the code that deletes site-lisp subdirectories from the default
5966 value of EMACSLOADPATH, as it is no longer needed.
5967 (check_windows_init_file): Now external, not static.
5968 Use Vload_path as is, without adding anything, as this function is now
5969 called when Vload_path is already set up.
5971 * w32.h (check_windows_init_file): Add prototype.
5973 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build
5974 directory, ignore the /*/i386/ tail in Vinvocation_directory, for
5975 compatibility with Posix platforms.
5976 (main): Move the call to check_windows_init_file to here from
5978 (decode_env_path) [WINDOWSNT]: Expand the %emacs_dir%/ prefix, if
5979 any, in the DEFALT argument into the root of the Emacs build or
5980 installation tree, as appropriate.
5982 * callproc.c (init_callproc_1): Call decode_env_path instead of
5983 doing its equivalent by hand.
5984 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
5985 the code that sets Vexec_path run on MS-Windows.
5987 * lread.c (init_lread): Add comments to #ifdef's.
5989 * msdos.c (dos_set_window_size, IT_update_begin)

5999 2012-08-03 Paul Eggert <eggert@cs.ucla.edu>
6001 Remove unnecessary casts involving pointers.
6002 These casts are no longer needed now that we assume C89 or later,
6003 since they involve casting to or from void *.

6005 (make_pure_float, make_pure_vector):
6006 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP):

6016 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
6017 Remove unnecessary pointer casts.
6018 * alloc.c (record_xmalloc): New function.
6019 * lisp.h (record_xmalloc): New decl.
6020 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
6021 more like a function. This is because the pointer cast is not
6022 needed. All uses changed.
6023 * print.c (print_string, print_error_message): Avoid length recalc.
6025 Improve fix for macroexp crash with debugging (Bug#12118).
6026 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
6027 ARRAY_MARK_FLAG when checking subscripts, because ASET is
6028 not supposed to be invoked from the garbage collector.
6029 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
6030 (gc_aset): New function, which is like ASET but can be
6031 used in the garbage collector.
6032 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)

6047 headers (most versions of MinGW w32api don't).
6048 (get_security_info, create_symbolic_link)
6049 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
6051 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
6052 in the argument file name.

6055 (sys_rename): Diagnose renaming of a symlink when the user doesn't
6056 have the required privileges.
6057 (get_file_security_desc_by_name): Rename from
6058 get_file_security_desc.
6059 (stat_worker): New function, with most of the guts of 'stat', and
6060 with addition of handling of symlinks and support for 'lstat'.
6061 If possible, get file's attributes and security information by
6062 handle, not by name. Produce S_IFLNK bit for symlinks, when
6063 called from 'lstat'.
6064 (stat, lstat): New functions, call 'stat_worker'.
6065 (symlink, readlink, careadlinkat): Rewritten to create and resolve
6066 symlinks when the underlying filesystem supports them.
6068 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
6070 Fix macroexp crash on Windows with debugging (Bug#12118).
6071 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
6072 checking subscripts; problem introduced with the recent
6073 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
6074 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
6075 since it's used in non-static inline functions now.
6077 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
6078 Don't assume buffer size fits in 'int'. Remove unused local.

6095 * category.c (CATEGORY_INLINE):
6096 * character.c (CHARACTER_INLINE):
6097 * charset.c (CHARSET_INLINE):
6098 * composite.c (COMPOSITE_INLINE):
6099 * dispnew.c (DISPEXTERN_INLINE):
6100 * sysdep.c (SYSTIME_INLINE):
6101 Define to EXTERN_INLINE, so that the corresponding functions
6102 are compiled into code.
6103 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
6104 (INLINE_HEADER_END): New macros.
6105 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

6127 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
6129 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
6130 This how ASET and AREF are supposed to work, and makes
6131 it easier to think about future improvements. See
6132 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
6133 * charset.h (set_charset_attr): New function.

6386 * s/aix4-2.h (sigmask): No need to undefine it, since syssignal.h
6387 does that unconditionally. Remove file, which is now empty.
6389 * s/freebsd.h, s/gnu-linux.h, s/sol2-6.h, s/unixware.h:
6392 2012-07-30 Paul Eggert <eggert@cs.ucla.edu>
6394 Export to GDB most of lisp.h's remaining object-like macros.

6510 * w32inevt.c: Include w32inevt.h.
6511 (w32_read_console_input): New inline function, calls either
6512 ReadConsoleInputA or ReadConsoleInputW, depending on the value of
6513 w32_console_unicode_input.
6514 (fill_queue): Call w32_read_console_input instead of ReadConsoleInput.
6515 (w32_kbd_patch_key, key_event): Use the codepage returned by
6516 GetConsoleCP, rather than the ANSI codepage returned by GetLocaleInfo.
6517 (key_event): use uChar.UnicodeChar only if
6518 w32_console_unicode_input is non-zero.

6545 * alloc.c (listn): Fix the order the arguments are consed onto the
6548 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
6549 enumeration constants, as PURE and HEAP are too general, and clash
6550 with other headers and sources, such as gmalloc.c and the
6551 MS-Windows system headers. All users changed.
6553 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
6555 Revert last save_excursion_save and save_excursion_restore changes.
6556 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

6566 2012-07-27 Paul Eggert <eggert@cs.ucla.edu>
6568 Improve GDB symbol export (Bug#12036).
6569 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
6570 arms of an 'if', not using conditional expressions; otherwise GDB
6571 complains about the types in the unevaluated arm when the argument
6572 is an integer literal.
6573 (xgetint): Simplify expression.
6574 * alloc.c (gdb_make_enums_visible): New constant. This ports to
6575 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
6576 Zaretskii in <http://bugs.gnu.org/12036#13>.
6577 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
6578 needed now that we have gdb_make_enums_visible.
6579 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
6580 (enum enum_USE_LSB_TAG):
6581 New enum types, packaging up enums that need to be exported to GDB.
6583 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>

6599 * xdisp.c (syms_of_xdisp): Likewise.
6600 * xfns.c (syms_of_xfns): Likewise.
6602 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
6604 Fast save_excursion_save and save_excursion_restore.
6605 * lisp.h (struct Lisp_Excursion): New data type.
6606 (PVEC_EXCURSION): New pseudovector type.
6607 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
6608 to deal with it. Adjust comments.
6609 (init_marker, attach_marker): New prototype.
6610 (unchain_marker): Adjust prototype.

6619 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
6621 Fix export of symbols to GDB (Bug#12036).
6622 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
6623 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
6624 emacs.c, as this is a more-suitable home. Had this been done earlier
6625 the fix for 12036 would have avoided some of the problems noted in
6626 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
6627 would have been more obvious.
6628 * emacs.c: Do not include <verify.h>; no longer needed.
6629 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
6630 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
6631 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
6632 Remove; now done in lisp.h.
6633 * lisp.h (PUBLISH_TO_GDB): New macro.

6635 (DATA_SEG_BITS): Use it.
6636 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
6637 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
6638 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
6639 not be usable in #if. This simplifies things.
6641 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
6643 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
6645 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
6647 Simplify export of symbols to GDB (Bug#12036).
6648 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
6649 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
6650 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
6651 Adjust to changes in lisp.h and emacs.c, by using
6652 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
6653 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
6654 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
6655 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
6656 instead of gdb_valbits.
6657 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
6658 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
6659 instead of gdb_array_mark_flag.
6660 (xboolvector): Get size from $->size, not $->header.size.
6661 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
6662 (xreload, hook-run, hookpost-run): Remove.
6663 * emacs.c: Include <verify.h>.
6664 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
6665 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
6667 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
6668 (gdb_USE_LSB_TAG): New enum constants.
6669 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
6670 Also define these as enum constants, so they're visible to GDB.
6671 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
6672 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
6673 as constants, so they're visible to GDB.
6674 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
6675 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
6676 Now enum constants, not macros, so they're visible to GDB.
6677 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
6678 more convenient now. All uses changed.
6679 (VALMASK) [USE_LSB_TAG]: Also define in this case.
6680 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
6682 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>
6684 Explicitly free restriction data that are not needed anymore.
6685 * editfns.c (save_restriction_restore): Free restriction data.
6687 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
6689 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
6690 add argument, tune behavior, and adjust all callers.
6692 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
6694 Use typedef for EMACS_INT, EMACS_UINT.
6695 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
6696 than macros. This simplifies debugging in the usual case, since
6697 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
6698 and it allows expressions involving EMACS_INT casts.
6699 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
6701 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>
6703 * nsterm.m (ns_read_socket): Return early if there is a modal
6706 2012-07-25 Martin Rudalics <rudalics@gmx.at>
6708 * frame.c (Fredirect_frame_focus): In doc-string don't mention
6709 that FOCUS-FRAME can be omitted.
6711 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
6713 Adjust buffer text indirection counters at the end of Fkill_buffer.
6714 * buffer.c (Fkill_buffer): Adjust indirection counters when the
6715 buffer is definitely dead. This should really fix an issue reported
6716 by Christoph Scholtes again. (Bug#12007).
6717 (init_buffer_once): Initialize indirection counters of
6718 buffer_defaults and buffer_local_symbols (for sanity and safety).
6720 2012-07-24 Eli Zaretskii <eliz@gnu.org>
6722 * xdisp.c (init_iterator): Don't compute dimensions of truncation
6723 and continuation glyphs on tooltip frames, leave them at zero.
6724 Avoids continued lines in tooltips. (Bug#11832)
6726 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
6728 Simplify copy_overlay.
6729 * buffer.c (copy_overlay): Simplify. Use build_marker.

6732 2012-07-23 Eli Zaretskii <eliz@gnu.org>
6734 * print.c (print_object): Don't crash when a frame's name is nil
6735 or invalid. (Bug#12025)
6737 * window.c (decode_any_window): Disable CHECK_LIVE_FRAME test, as
6738 it signals an error when a tooltip frame is being created.
6740 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
6742 Cleanup miscellaneous objects allocation and initialization.
6743 * alloc.c (allocate_misc): Change to static. Add argument to
6744 specify the subtype. Adjust comment and users.
6745 (build_overlay): New function.
6746 * buffer.c (copy_overlays, Fmake_overlay): Use it.
6747 * lisp.h (struct Lisp_Overlay): Remove obsolete comment.
6748 (allocate_misc): Remove prototype.
6749 (build_overlay): Add prototype.
6751 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
6753 Swap buffer text indirection counters in Fbuffer_swap_text.
6754 * buffer.c (Fbuffer_swap_text): Swap indirections too.

7514 * s/aix4-2.h (unix): Remove; no longer needed.
7516 EMACS_TIME simplification (Bug#11875).
7517 This replaces macros (which typically do not work in GDB)

7519 The functional style also makes code easier to read and maintain.
7520 * systime.h: Include <sys/time.h> on all hosts, not just if
7521 WINDOWSNT, since 'struct timeval' is needed in general.

7556 (menu_separator_name_p):

7561 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
7562 Prefer snprintf to strncpy.
7563 * nsterm.m (ns_term_init):
7564 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
7565 * nsterm.m (ns_term_init):
7566 Avoid the need for strncpy, by using build_string or
7567 make_unibyte_string directly. Use dtoastr, not snprintf.
7568 * process.c (Fmake_network_process): Diagnose service names that
7569 are too long, rather than silently truncating them or creating
7570 non-null-terminated names.
7571 (Fnetwork_interface_info): Likewise, for interface names.
7572 * sysdep.c (system_process_attributes) [GNU_LINUX]:
7573 Prefer sprintf to strncat.

7587 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
7588 where argument type is known to be a Lisp_Cons.

7600 Optimize pure C strings initialization.
7601 * lisp.h (make_pure_string): Fix prototype.
7602 (build_pure_c_string): New function, defined as static inline. This

7604 the function is called with compile-time constant argument.
7605 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
7606 argument, adjust users accordingly. Use build_pure_c_string where

7639 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
7640 We include usg5-4-common.h, which defines them both.
7642 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
7643 O_RDONLY already includes it).
7645 Stop ns builds setting the EMACSLOADPATH environment variable.
7646 * nsterm.m (ns_load_path): Rename from ns_init_paths.
7647 Now it does not set EMACSLOADPATH, just returns the load-path string.
7648 * nsterm.h: Update accordingly.
7649 * lread.c [HAVE_NS]: Include nsterm.h.
7650 (init_lread) [HAVE_NS]: Use ns_load_path.
7651 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
7653 2012-07-09 Glenn Morris <rgm@gnu.org>
7655 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
7656 since the included bsd-common.h does so.
7658 Stop ns builds setting the EMACSPATH environment variable.
7659 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
7660 (ns_init_paths): Do not set EMACSPATH.
7661 * nsterm.h (ns_exec_path): Add it.
7662 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
7665 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
7667 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
7669 * process.c (wait_reading_process_output): 'waitchannels' was unset
7670 when read_kbd || !NILP (wait_for_cell); fix this.
7672 Add GCC-style 'const' attribute to functions that can use it.
7673 * character.h (char_resolve_modifier_mask):
7674 * keyboard.h (make_ctrl_char):
7675 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)

7684 Add decls with ATTRIBUTE_CONST.
7686 Minor improvements to make_formatted_string.
7687 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
7688 where int is good enough, as vsprintf returns an int.
7689 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
7691 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
7693 Use make_formatted_string to avoid double length calculation.
7694 * lisp.h (make_formatted_string): New prototype.
7695 * alloc.c (make_formatted_string): New function.

7718 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
7720 Move marker debugging code under MARKER_DEBUG.
7721 * marker.c (MARKER_DEBUG): Move marker debugging code under
7722 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
7723 for bootstrap with --enable-checking (~3x slowdown reported
7724 by Juanma Barranquero <lekktu@gmail.com>).
7725 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
7727 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
7729 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
7730 See <http://bugs.gnu.org/11825#29>.
7732 2012-07-08 Eli Zaretskii <eliz@gnu.org>
7734 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
7735 has no font, use the frame's font. (Bug#11813)
7736 (display_line): Add commentary about displaying truncation glyphs
7738 (produce_special_glyphs): Move here from term.c.
7740 * term.c (produce_special_glyphs): Move to xdisp.c.
7742 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
7745 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
7747 * xdisp.c (display_line): Avoid warning about implicit declaration
7750 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
7752 * lisp.h: Remove empty conditional.
7754 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
7756 * lread.c (load_path_check): Now static.
7758 Fix some minor --with-ns problems found by static checking.
7759 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
7760 (x_set_font) [!HAVE_X_WINDOWS]:
7761 * image.c (xpm_load_image) [HAVE_NS]:
7762 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
7763 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
7764 Remove unused local.
7765 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
7766 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
7767 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
7768 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
7769 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
7770 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
7771 Fix pointer signedness problem.
7772 * xfaces.c (FRAME_X_FONT_TABLE):
7773 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
7775 2012-07-07 Glenn Morris <rgm@gnu.org>
7777 * lread.c (load_path_check): New function, split from init_lread.
7778 (init_lread): Reorganize. Motivation:
7779 If EMACSLOADPATH is set, check/warn about that rather than the
7780 defaults, which we are not going to use. Hence we can remove
7781 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
7782 Don't warn if site-lisp directories are missing.
7783 If not installed, start from a blank load-path, since
7784 PATH_LOADSEARCH refers to the eventual installation directories.
7786 2012-07-07 Eli Zaretskii <eliz@gnu.org>
7788 Support truncation and continuation glyphs on GUI frames, when
7789 fringes are disabled. (Bug#11832)
7790 * xdisp.c (init_iterator): Get dimensions of truncation and
7791 continuation glyphs even if on GUI frames.
7792 Adjust it->last_visible_x on GUI frames when the left or right fringes,
7793 or both, are absent.
7794 (start_display, move_it_in_display_line_to): Handle the case of a
7795 GUI frame without a fringe to display continuation or truncation
7797 (insert_left_trunc_glyphs): Support GUI frames: make sure
7798 truncation glyphs overwrite enough glyphs from the current line to
7799 have sufficient space in pixels.
7800 (display_line): Support truncation and continuation glyphs on GUI
7801 frames. If some spare pixels are left on the line after inserting
7802 the truncation glyphs, fill that space with a stretch glyph of a
7803 suitably computed width.
7805 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
7806 produce_glyphs, to support GUI sessions.
7808 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
7810 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
7812 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
7814 Do not require float-time's arg to fit in time_t (Bug#11825).
7815 This works better on hosts where time_t is unsigned, and where
7816 float-time is applied to the (negative) difference between two times.
7817 * editfns.c (decode_time_components): Last arg is now double *,
7818 not int *, and means to store all the result as a double, without
7819 worrying about whether the seconds part fits in time_t.
7820 All callers changed.
7821 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
7822 All callers changed.
7823 (Ffloat_time): Do not fail merely because the specified time falls
7824 outside of time_t range.
7826 2012-07-07 Glenn Morris <rgm@gnu.org>
7828 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

7834 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
7835 Update dependencies.
7837 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
7839 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>

7843 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
7844 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
7845 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.

7848 * xfont.c (compare_font_names): Redo to omit the need for casts.
7850 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
7852 * xfns.c (Fx_change_window_property): Doc fix.
7853 * w32fns.c (Fx_change_window_property): Doc fix.
7855 * w32fns.c (Fx_window_property): Accept the same arguments as the
7856 X Windows version. Doc fix.
7857 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
7859 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
7860 Eli Zaretskii <eliz@gnu.org>
7862 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
7863 Windows-specific code from nt/config.nt moved here.
7864 Obsolete settings removed.
7866 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
7868 * process.c: Avoid unnecessary calls to gettime.
7869 (wait_reading_process_output): Don't get the time of day
7870 when gobbling data immediately and not waiting, as there's no need
7871 for it in that case. This removes a FIXME.
7873 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
7875 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
7876 is defined (Bug#11768).
7878 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
7880 Fix marker debugging code.
7881 * marker.c (byte_char_debug_check): Do not perform the check
7882 if buffer is not multibyte.
7883 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
7884 Call byte_char_debug_check with correct arguments.
7886 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
7888 Compile marker debugging code only if ENABLE_CHECKING is defined.
7889 * marker.c (byte_char_debug_check, count_markers):
7890 Use only if ENABLE_CHECKING is defined.
7891 (byte_debug_flag): Remove.
7892 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
7893 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
7895 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
7897 Avoid code repetition in marker-related functions.
7898 * marker.c (attach_marker): New function.
7899 (Fset_marker, set_marker_restricted, set_marker_both)
7900 (set_marker_restricted_both): Use it.
7901 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
7902 Consistently rename charno to charpos.
7903 (marker_position): Add eassert.
7904 (marker_byte_position): Convert to eassert.

7920 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
7921 (save_restriction_save): Use build_marker.
7922 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
7923 * window.c (save_window_save): Likewise.
7925 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
7927 Do not use Fdelete_overlay in delete_all_overlays
7928 to avoid redundant calls to unchain_overlay.
7929 * buffer.c (drop_overlay): New function.
7930 (delete_all_overlays, Fdelete_overlay): Use it.
7931 * minibuf.c (get_minibuffer): Fix comment.
7933 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
7935 Port to OpenBSD 5.1 amd64.
7936 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
7937 This is needed for OpenBSD, and should be harmless on all BSD systems.
7938 Also, include <sys/sysctl.h>, as it should be available on all
7939 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
7940 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
7941 use p_pid member, not kp_proc.pid.
7943 2012-07-06 Glenn Morris <rgm@gnu.org>
7945 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
7947 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
7949 More xmalloc and related cleanup.
7950 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
7951 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:

7957 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
7958 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
7960 Omit needless casts involving void * pointers and allocation.
7961 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
7962 as the former is more robust if P's type is changed.
7963 Prefer xzalloc to xmalloc + memset 0.
7964 Simplify malloc-or-realloc to realloc.
7965 Don't worry about xmalloc returning a null pointer.
7966 Prefer xstrdup to xmalloc + strcpy.
7967 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
7969 * keyboard.c (apply_modifiers_uncached): Prefer local array to
7970 alloca of a constant.
7972 2012-07-05 Eli Zaretskii <eliz@gnu.org>
7974 * xdisp.c (display_line): Fix horizontal pixel coordinates when
7975 hscroll is larger than the line width. Fixes long and futile
7976 looping inside extend_face_to_end_of_line (on a TTY) producing
7977 glyphs that are not needed and thrown away.
7979 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
7981 * marker.c (set_marker_restricted_both): Simplify by using

7995 followed by gtk_box_set_homogeneous (Bug#11768).
7996 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
7997 (update_theme_scrollbar_width, xg_create_scroll_bar):
7998 Use gtk_scrollbar_new (Bug#11768).
7999 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
8000 (is_box_type): New function (Bug#11768).
8001 (xg_tool_item_stale_p): Call is_box_type.
8002 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
8003 with default display (Bug#11768).

8007 * xdisp.c (window_hscroll_limited): New function.
8008 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
8009 coordinates when window's hscroll is set to insanely large
8012 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
8014 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

8081 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
8082 This should be fixed in a better way; see Eli Zaretskii in
8083 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
8084 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
8086 * fileio.c (time_error_value): Rename from special_mtime.
8087 The old name's problems were noted by Eli Zaretskii in
8088 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
8090 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
8091 This variable's comment says Emacs needs at least one GDB-visible
8092 symbol of type enum pvec_type, to work around GDB problems.
8093 The symbol's value doesn't matter.
8095 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
8096 that causes compilation to fail on pre-C99 compilers.
8098 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
8100 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

8111 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
8112 * lisp.h (enum pvec_type): Use fewer bits.
8113 (PSEUDOVECTOR_SIZE_BITS): New constant.
8114 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
8115 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
8116 change in pvec_type.
8117 (PSEUDOVECTOR_TYPEP): New macro.
8118 (TYPED_PSEUDOVECTORP): Use it.
8119 * fns.c (internal_equal): Adapt code to extract pvectype.

8121 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
8122 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
8123 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
8124 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
8125 (sweep_vectors): Use it. Use local var `total_bytes' instead of
8126 abusing vector->header.next.nbytes.
8127 (live_vector_p): Use PVEC_TYPE.
8128 (mark_object): Adapt code to extract pvectype. Use switch.
8130 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8132 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
8133 Tighten new eassert a bit.
8135 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
8137 Fix compilation with --enable-gcc-warnings and -O1
8139 * doprnt.c (doprnt): Change type of tem to int, initialize
8140 to avoid compiler warning. Add eassert.
8141 * search.c (simple_search): Initialize match_byte to avoid
8142 compiler warning. Add eassert.
8144 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8146 Avoid weird behavior with large horizontal scrolls.
8147 Without this change, for example, large hscroll values would
8148 mess up Emacs's display on Fedora 15 x86, presumably due to
8149 overflows in int calculations in the display code.
8150 Also, if buffers had long lines, Emacs would freeze.
8151 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
8152 (set_window_hscroll): New function, containing the old guts of
8153 Fset_window_hscroll. Return the clipped value.
8154 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
8155 This avoids the need to check against PTRDIFF_MAX.
8157 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
8159 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
8161 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
8163 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8165 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
8166 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
8167 since GCC 4.4.6 issues a bogus warning for them.
8169 Fix bugs in file timestamp newness comparisons.
8170 * fileio.c (Ffile_newer_than_file_p):
8171 * lread.c (Fload): Use full timestamp resolution of files,
8172 not just the 1-second resolution, so that files that are only
8173 slightly newer still count as newer.
8174 * fileio.c (Ffile_newer_than_file_p): Don't assume file
8175 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
8177 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
8179 * fileio.c: Improve handling of file time marker. (Bug#11852)
8180 (special_mtime): New function.
8181 (Finsert_file_contents, Fverify_visited_file_modtime):
8182 Use it to set special mtime values consistently.
8184 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
8186 * fileio.c (Finsert_file_contents): Properly handle st_mtime
8187 marker for non-existing file. (Bug#11852)
8189 2012-07-03 Glenn Morris <rgm@gnu.org>
8191 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
8192 and did not make it into globals.h).
8194 2012-07-03 Tom Tromey <tromey@redhat.com>
8196 * window.c (Fset_window_margins, Fset_window_fringes)
8197 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.

8221 * intervals.h: Remove EXFUNs.
8222 * fontset.h: Remove EXFUN.
8223 * font.h: Remove EXFUNs.
8224 * dosfns.c (system_process_attributes): Remove EXFUN.

8227 * w32term.h: Remove EXFUNs.
8228 * window.h: Remove EXFUNs.

8230 * xterm.h: Remove EXFUN.
8232 2012-07-03 Glenn Morris <rgm@gnu.org>
8234 * lisp.h (Frandom): Make it visible to C.
8235 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
8236 buffer for invisible buffers. (Bug#1229)
8238 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8240 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
8241 values which aren't power of 2.
8242 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
8243 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
8246 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
8248 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
8250 * alloc.c (mark_object): Revert part of last patch to use `switch'.
8252 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8254 * alloc.c (allocate_vector_block): Remove redundant
8255 calls to mallopt if DOUG_LEA_MALLOC is defined.
8256 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
8257 avoid calls to mallopt if zero_vector is returned.
8259 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8261 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
8262 is enabled, avoid dereferencing NULL current_sblock if
8265 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8267 Cleanup basic buffer management.
8268 * buffer.h (struct buffer): Change layout to use generic vector
8269 marking code. Fix some comments. Change type of 'clip_changed'
8270 to bitfield. Remove unused #ifndef old.
8271 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
8272 (GET_OVERLAYS_AT): Fix indentation.
8273 (for_each_per_buffer_object_at): New macro.
8274 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
8275 (Fbuffer_local_variables): Use it.
8276 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
8277 * alloc.c (allocate_buffer): Adjust to match new layout of
8278 struct buffer. Fix comment.
8279 (mark_overlay): New function.
8280 (mark_buffer): Use it. Use mark_vectorlike to mark normal
8281 Lisp area of struct buffer.
8282 (mark_object): Use it. Adjust marking of misc objects
8283 and related comments.
8285 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
8287 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
8288 wrapper that is not needed because the wrapped code is a no-op (zero
8289 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
8290 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
8292 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
8294 * alloc.c (mark_buffer): Simplify. Remove prototype.
8295 (mark_object): Add comment. Reorganize marking of vector-like
8296 objects. Use CHECK_LIVE for all vector-like objects except buffers
8297 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
8298 Avoid redundant calls to mark_vectorlike for bool vectors.
8300 2012-06-30 Glenn Morris <rgm@gnu.org>
8302 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
8304 * epaths.in (PATH_SITELOADSEARCH): New.
8305 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
8306 This is rather than relying on --enable-locallisppath elements
8307 having "site-lisp" in their names. (Bug#10208#25, 11658)
8309 2012-06-30 Eli Zaretskii <eliz@gnu.org>
8311 * w32proc.c (sys_select): Accept and ignore one more argument.
8313 * w32.c (emacs_gnutls_pull): Call select with one more argument.
8315 * sysselect.h [DOS_NT]: Don't include sys/select.h.
8316 (pselect) [!MS_DOS]: Redirect to sys_select.
8318 * sysdep.c: Don't include dos.h and dosfns.h.
8320 * process.c (sys_select):
8321 * msdos.c (sys_select): Accept one more argument and ignore it.
8323 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
8324 adapt data types and code to that.
8327 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
8328 which clashes with the gnulib function of the same name.
8330 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
8332 * font.c (font_style_to_value, font_style_symbolic)
8333 (font_prop_validate_style): Add type checks for values in
8336 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
8338 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
8341 2012-06-29 Eli Zaretskii <eliz@gnu.org>
8343 * xdisp.c (try_window_id): Undo last change.
8345 * w32.c (getwd): Adjust commentary about startup_dir.
8346 (init_environment): Always call sys_access, even in non-MSVC
8347 builds. Don't chdir to the directory of the Emacs executable.
8348 This undoes code from 1997 which was justified by the need to
8349 "avoid conflicts when removing and renaming directories". But its
8350 downside was that every relative file name was being interpreted
8351 relative to the directory of the Emacs executable, which can never
8352 be TRT. In particular, it broke sys_access when called with
8353 relative file names.
8354 (sys_access): Map GetLastError to errno.
8356 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8358 * window.h (struct window): Change type of 'fringes_outside_margins'

8362 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
8365 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>

8368 Add QUIT to make the loop interruptible.
8370 2012-06-29 Glenn Morris <rgm@gnu.org>
8372 * charset.c (init_charset): Make lack of etc/charsets fatal.
8374 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8376 * editfns.c (region_limit): Fix type mismatch.
8378 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8380 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
8381 undefined. Convert from xassert to eassert.
8382 * nsmenu.m: Convert from xassert to eassert.
8383 * nsterm.m: Likewise.
8385 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
8387 * editfns.c (region_limit): Clip to narrowing (bug#11770).
8389 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
8391 Avoid integer overflow on scroll-left and scroll-right.
8392 * window.c (HSCROLL_MAX): New macro.
8393 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
8394 overflow when requested scroll falls outside ptrdiff_t range.
8396 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
8398 * window.h (struct window): Change type of 'hscroll',
8399 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
8400 'last_modified' and 'last_overlay_modified' to EMACS_INT.
8401 Adjust users accordingly.
8402 * xdisp.c (try_cursor_movement): Replace type check with eassert.
8403 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
8404 from EMACS_INT to ptrdiff_t.
8405 (make_window): Omit redundant initialization.
8407 2012-06-28 Juanma Barranquero <lekktu@gmail.com>

8411 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>

8480 * alloc.c (allocate_string): Omit intervals initialization.
8481 * alloc.c (make_uninit_multibyte_string): Initialize intervals
8482 as in make_pure_string and make_pure_c_string.

8538 * alloc.c: Remove build_string.
8539 * lisp.h: Define build_string as static inline. This provides
8540 a better opportunity to optimize away calls to strlen when the
8541 function is called with compile-time constant argument.
8542 * image.c (imagemagick_error): Convert to build_string.
8543 * w32proc.c (sys_spawnve): Likewise.
8544 * xterm.c (x_term_init): Likewise.
8546 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
8548 Use sprintf return value instead of invoking strlen on result.
8549 In the old days this wasn't portable, since some sprintf
8550 implementations returned char *. But they died out years ago and
8551 Emacs already assumes sprintf returns int.
8552 Similarly for float_to_string.
8553 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
8554 * ccl.c (ccl_driver):
8555 * character.c (string_escape_byte8):

8560 * xfns.c (syms_of_xfns):
8561 Use sprintf or float_to_string result to avoid need to call strlen.
8562 * data.c (Fnumber_to_string):
8563 Use make_unibyte_string, since the string must be ASCII.
8564 * lisp.h, print.c (float_to_string): Now returns int length.
8565 * term.c (produce_glyphless_glyph):
8566 Use sprintf result rather than recomputing it.
8568 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
8569 * Makefile.in (ALL_CFLAGS):
8570 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

8576 strcasecmp if available.

8601 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

8606 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
8607 instead of truncating it to 63 (admittedly a generous limit).
8609 * process.c: Fix spelling and caps in comments.
8611 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>

8703 language ID in the event parameters.
8705 * w32term.c (w32_read_socket): Put the new keyboard codepage into

8737 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
8739 Support higher-resolution time stamps (Bug#9000).
8740 The time stamps are only nanosecond-resolution at the C level,
8741 since that's the best that any real-world system supports now.
8742 But they are picosecond-resolution at the Lisp level, as that's
8743 easy, and leaves room for future OS improvements.
8745 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
8748 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
8749 Don't get current time unless it's needed.
8751 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
8752 now provides it if it's absent.
8753 (start_atimer): Port to higher-res time stamps.
8754 Check for time stamp overflow. Don't get current time more
8755 often than is needed.
8757 * buffer.h (struct buffer): Buffer modtime now has high resolution.
8758 Include systime.h, not time.h.
8759 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.

8765 (struct image): Timestamp now has higher resolution.
8767 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
8768 has at least microseconds now. All uses removed.
8769 (update_frame, update_single_window, update_window, update_frame_1)
8770 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
8771 (duration_to_sec_usec): Remove; no longer needed.
8773 * editfns.c (time_overflow): Now extern.

8779 (decode_time_components, lisp_seconds_argument): New functions.
8780 (make_time): Now static.
8781 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
8782 Report an error if the time is invalid, rather than having the caller
8785 * fileio.c: Include <stat-time.h>
8786 (Fcopy_file): Copy higher-resolution time stamps.
8787 Prefer to set the time stamp via a file descriptor if that works.

8789 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
8790 (Fvisited_file_modtime, Fset_visited_file_modtime):
8791 Support higher-resolution time stamps.
8793 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
8795 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
8797 * image.c (prepare_image_for_display, clear_image_cache)
8798 (lookup_image): Port to higer-resolution time stamps.
8800 * keyboard.c (start_polling, bind_polling_period):
8801 Check for time stamp overflow.
8802 (read_char, kbd_buffer_get_event, timer_start_idle)
8803 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
8804 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
8805 Port to higher-resolution time stamps. Do not assume time_t is signed.
8806 (decode_timer): New function. Timers are now vectors of length 9,
8807 not 8, to accommodate the picosecond component.
8808 (timer_check_2): Use it.
8810 * nsterm.m (select_timeout, timeval_subtract): Remove.
8811 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
8812 as they're a bit more accurate and handle overflow better.
8813 (ns_select): Change prototype to be compatible with pselect.
8814 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
8815 * nsterm.h (ns_select): Adjust prototype.
8817 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
8818 us-resolution time stamps.
8819 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
8821 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
8823 * lisp.h (time_overflow): New decl.
8824 (wait_reading_process_output): First arg is now intmax_t, not int,
8825 to accommodate larger waits.
8827 * process.h (struct Lisp_Process.read_output_delay):
8828 Now counts nanoseconds, not microseconds.
8829 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about

8832 (wait_reading_process_output):
8833 Port to ns-resolution time stamps.
8834 (Faccept_process_output, wait_reading_process_output):
8835 Check for time stamp overflow. Do not assume time_t is signed.
8836 (select_wrapper): Remove; we now use pselect.
8837 (Fprocess_attributes): Now generates ns-resolution time stamps.
8839 * sysdep.c: Include utimens.h. Don't include utime.h
8840 or worry about struct utimbuf; gnulib does that for us now.
8841 (gettimeofday): Remove; gnulib provides a substitute.
8842 (make_timeval): New function.
8843 (set_file_times): Now sets ns-resolution time stamps.
8844 New arg FD; all uses changed.
8845 (time_from_jiffies, ltime_from_jiffies, get_up_time)
8846 (system_process_attributes):
8847 Now returns ns-resolution time stamp. All uses changed.
8848 Check for time stamp overflow.
8850 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
8851 provides a substitute now.
8853 * systime.h: Include timespec.h rather than sys/time.h and time.h,
8854 since it guarantees struct timespec.
8855 (EMACS_TIME): Now struct timespec, so that we can support
8856 ns-resolution time stamps.
8857 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
8858 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
8859 (EMACS_USECS): Remove.
8860 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
8861 so multiply the arg by 1000 before storing it.
8862 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
8864 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
8865 Port to ns-resolution time stamps.
8866 (EMACS_TIME_NEG_P): Remove; replaced by....
8867 (EMACS_TIME_SIGN): New macro.
8868 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
8869 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
8870 (set_file_times, make_time, lisp_time_argument): Adjust signature.
8871 (make_timeval, make_lisp_time, decode_time_components): New decls.
8872 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
8873 that it mishandled time_t overflow. You can't compare by subtracting!
8874 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
8875 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
8877 * term.c: Include <sys/time.h>.
8878 (timeval_to_Time): New function, for proper overflow wraparound.

8883 (Fprimitive_undo): Use them when restoring time stamps.
8885 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
8886 (w32_get_internal_run_time):
8887 Port to higher-resolution Emacs time stamps.
8888 (ltime): Now accepts single 64-bit integer, as that's more convenient
8891 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
8893 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
8894 for compatibility with pselect. Support ns-resolution time stamps.
8896 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
8898 * xselect.c (wait_for_property_change, x_get_foreign_selection):
8899 Check for time stamp overflow, and support ns-resolution time stamps.
8901 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
8902 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
8903 (timeval_subtract): Remove; no longer needed.
8904 (XTflash, XTring_bell, x_wait_for_event):
8905 Port to ns-resolution time stamps. Don't assume time_t is signed.
8907 2012-06-22 Chong Yidong <cyd@gnu.org>
8909 * xdisp.c (x_consider_frame_title): Revert last change.
8911 2012-06-22 Eli Zaretskii <eliz@gnu.org>
8913 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
8914 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
8915 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
8916 staticidx goes up to 1597 out of 1600 = 0x640.)
8918 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
8920 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
8921 Otherwise, the umask might be mistakenly 0 while handling input signals.
8923 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
8925 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

8931 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
8932 access to `contents' member of Lisp_Vector objects with AREF and ASET
8935 2012-06-19 Chong Yidong <cyd@gnu.org>
8937 * frame.c (delete_frame): When selecting a frame on a different
8938 text terminal, do not alter the terminal's top-frame.

8942 (unwind_format_mode_line): Restore them.
8943 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
8945 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
8946 since tty frames can be explicitly named.
8947 (prepare_menu_bars): Likewise.
8949 * term.c (Ftty_top_frame): New function.
8951 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

8954 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
8955 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
8956 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
8957 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
8958 (METER_1, METER_2): Simplify.
8960 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
8962 * data.c (Fdefalias): Return `symbol' (bug#11686).
8964 2012-06-18 Martin Rudalics <rudalics@gmx.at>
8966 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
8967 gets killed during executing of this function (Bug#11665).
8968 Try to always return Qt when the buffer has been actually killed.
8969 (Vkill_buffer_query_functions): In doc-string say that functions
8970 run by this hook should not change the current buffer.
8972 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
8974 Fix recently-introduced process.c problems found by static checking.
8975 * process.c (write_queue_push, write_queue_pop, send_process):
8976 Use ptrdiff_t, not int or EMACS_INT, for buffer lengths and offsets.

8978 (send_process): Remove unused local.
8980 2012-06-17 Chong Yidong <cyd@gnu.org>

8983 frames that are not on top.
8985 2012-06-17 Troels Nielsen <bn.troels@gmail.com>
8987 * process.c (make_process): Initialize write_queue.
8988 (write_queue_push, write_queue_pop): New functions.

8992 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
8994 * lisp.h (eassert): Assume C89 or later.
8995 This removes the need for CHECK.
8996 (CHECK): Remove. Its comments about always evaluating its
8997 argument were confusing, as 'eassert' typically does not evaluate
9000 * coding.c (produce_chars): Use ptrdiff_t, not int.
9002 * xterm.c (x_draw_underwave): Check for integer overflow.
9003 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

9176 USE_LISP_UNION_TYPE + USE_LSB_TAG cleanup (Bug#11604)
9177 * alloc.c (make_number) [!defined make_number]:

9187 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
9188 code works fine either way, and efficiency is not a concern here,
9189 as the union type is for debugging, not for production.
9190 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
9191 Use an inline function on all platforms when using the union type,
9192 since this is simpler and 'static inline' can be used portably
9194 (LISP_INITIALLY_ZERO): New macro.
9195 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
9196 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.

9278 * xdisp.c (vmessage): Treat frame message as multibyte.
9279 Without this change, (let ((§ 1)) (make-variable-buffer-local '§))

9299 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
9301 2012-06-08 Eli Zaretskii <eliz@gnu.org>
9303 * alloc.c (allocate_vectorlike): Fix last change.

9307 Block-based vector allocation of small vectors.
9308 * lisp.h (struct vectorlike_header): New field `nbytes',
9309 adjust comment accordingly.
9310 * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'

9334 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
9336 * doprnt.c (doprnt): Truncate multibyte char correctly.
9337 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
9338 would mishandle a string argument "Xc" if X was a multibyte
9339 character of length 2: it would truncate after X's first byte
9340 rather than including all of X.
9342 2012-06-06 Chong Yidong <cyd@gnu.org>
9344 * buffer.c (word_wrap): Doc fix.

9393 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
9394 Convert pctcpu and pctmem to Lisp float properly.
9395 Let the compiler fold better, as 100.0/0x8000 is exact.
9397 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
9399 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
9402 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
9404 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
9406 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
9408 For a 'struct window', replace some Lisp_Object fields to
9409 bitfields where appropriate, remove unused fields.
9410 * window.h (struct window): Remove unused 'last_mark_x' and
9411 'last_mark_y' fields. Rename 'mini_p' field to 'mini',

9413 Change type of 'force_start', 'optional_new_start',
9414 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
9415 fields from Lisp_Object to bitfield. Adjust users accordingly.

9421 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:

9423 and 'double' in a couple of places.
9425 2012-05-31 Eli Zaretskii <eliz@gnu.org>
9427 * xdisp.c (handle_stop): Detect whether we have overlay strings
9428 loaded by testing it->current.overlay_string_index to be
9429 non-negative, instead of checking whether n_overlay_strings is
9430 positive. (Bug#11587)
9432 2012-05-31 Chong Yidong <cyd@gnu.org>
9434 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

9440 * search.c (search_buffer): Remove calls to
9441 r_alloc_inhibit_buffer_relocation, as it is now called by
9442 maybe_unify_char, which was the cause of relocation of buffer text
9445 2012-05-31 Eli Zaretskii <eliz@gnu.org>
9447 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
9448 for the duration of call to load_charset, to avoid problems with
9449 callers of maybe_unify_char that access buffer text through C
9452 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
9453 decrement the inhibition flag, instead of just setting or
9456 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
9458 Remove obsolete '#define static' cruft.
9459 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
9460 This #undef was "temporary" in 2000; it is no longer needed
9461 now that '#define static' has gone away.
9462 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
9463 (gray_bitmap_bits): Remove; no longer needed.
9464 All uses replaced with definiens.

9476 (safe_bcopy): Remove decl; no longer has that name.
9477 (main): Coalesce #if into single bit of code, for simplicity.

9508 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
9509 Bug#9642, but explicitly check that the buffer the overlay would
9510 be moved to is live and rearrange lines to make sure that errors
9511 will not put the overlay in an inconsistent state.
9512 (Fdelete_overlay): Cosmetics.
9514 2012-05-28 Eli Zaretskii <eliz@gnu.org>
9516 * w32term.c (my_bring_window_to_top): New function.
9517 (x_raise_frame): Use handle returned by DeferWindowPos, which

9552 the others were already declared.
9554 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
9555 before checking whether it's out of range. Put the check inside
9557 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.

9566 * lisp.h [REL_ALLOC]: Add prototypes for external functions
9567 defined on ralloc.c.
9569 * buffer.c [REL_ALLOC]: Remove prototypes of
9570 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
9571 they are now on lisp.h.
9573 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
9575 * search.c (search_buffer): Use it to inhibit relocation of buffer
9576 text while re_search_2 is doing its job, because re_search_2 is
9577 passed C pointers to buffer text. (Bug#11519)
9579 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
9582 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
9583 state after an additional call to move_it_in_display_line_to, keep
9584 the values of it->max_ascent and it->max_descent found for the
9586 (pos_visible_p): Revert the comparison against bottom_y to what it
9587 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
9590 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
9592 Fix coding-related core dumps with gcc -ftrapv.
9593 The code was computing A - B, where A and B are pointers, and B is
9594 random garbage. This can lead to core dumps on platforms that
9595 have special pointer registers, and it also leads to core dumps on
9596 x86-64 when compiled with gcc -ftrapv. The fix is to compute
9597 A - B only when B is initialized properly.
9598 * coding.c (coding_set_source, coding_set_destination): Return void.
9599 (coding_change_source, coding_change_destinations): New functions,
9600 with the old behaviors of coding_set_source and coding_set_destination.

9616 (initialize_w32_display): Initialize mouse-highlight data.
9618 * w32inevt.c: Include termchar.h and window.h.
9619 (do_mouse_event): Support mouse-autoselect-window. When the mouse
9620 moves, call note_mouse_highlight. If help_echo changed, call
9621 gen_help_event to produce help-echo message in the echo area.
9622 Call clear_mouse_face if mouse_face_hidden is set in the mouse
9625 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
9627 * lread.c (read1): Simplify slightly to avoid an overflow warning
9628 with GCC 4.7.0 on x86-64.
9630 2012-05-26 Eli Zaretskii <eliz@gnu.org>
9632 * bidi.c (bidi_mirror_char): Revert last change: an int is
9633 definitely wide enough here.
9635 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>

9649 Use int, not EMACS_INT, where int is wide enough.

9669 (Foverlay_recenter, last_overlay_modification_hooks_used)
9670 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
9671 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9672 (validate_region): Omit unnecessary test for b <= e,
9673 since that's guaranteed by the previous test.
9674 (adjust_overlays_for_delete): Avoid pos + length overflow.
9675 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
9676 (report_overlay_modification):
9677 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9678 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):

9687 not int, to avoid needless 32-bit limit on 64-bit hosts.
9688 (exec_byte_code): Use tighter memory-full test, one that checks
9689 for alloca overflow. Don't compute the address of the object just
9690 before an array, as that's not portable. Use EMACS_INT, not
9691 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
9692 * callint.c (Fcall_interactively):
9693 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

9705 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9706 (casify_object): Avoid integer overflow when overallocating buffer.
9707 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
9708 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
9709 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
9710 * category.h (CATEGORYP): Don't assume arg is nonnegative.
9711 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
9712 integers are now checked earlier. All uses replaced with XINT.
9714 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9715 For CCL_MapSingle, check that content and value are in int range.
9716 (ccl_driver, Fregister_code_conversion_map):
9717 Check that Vcode_version_map_vector is a vector.
9718 (resolve_symbol_ccl_program): Check that vector header is in range.
9719 Always copy the vector, so that we can check its contents reliably
9720 now rather than having to recheck each instruction as it's being
9721 executed. Check that vector words fit in 'int'.
9722 (ccl_get_compiled_code, Fregister_ccl_program)
9723 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
9724 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
9725 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
9726 contents are in range.
9727 (Fccl_execute_on_string): Check that status is in range.
9728 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
9729 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
9730 Accept and return EMACS_INT, not int, because callers can pass values

9737 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

9739 avoid mishandling large integers.

9750 Don't rely on undefined behavior with signed left shift overflow.
9751 Don't assume unsigned int fits into fixnum, or that fixnum fits
9752 into unsigned int. Don't require max_code to be a valid fixnum;
9753 that's not true for gb10830 4-byte on a 32-bit host. Allow
9754 invalid_code to be a cons, for the same reason. Require code_offset
9755 to be a character. Avoid int overflow if max_char is close
9757 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
9758 this is intended anyway and avoids some undefined behavior.
9759 (load_charset_map): Pass unsigned, not int, as 2nd arg of
9760 INDEX_TO_CODE_POINT, as that's what it expects.
9761 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
9762 * charset.h (DECODE_CHAR): Return int, not unsigned;
9763 this is what was intended anyway, and it avoids undefined behavior.
9764 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
9765 integer-overflow issues.
9766 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
9767 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
9768 where the argument is EMACS_INT, and this behavior is not intended.
9769 * chartab.c (Fmake_char_table, Fset_char_table_range)
9770 (uniprop_get_decoder, uniprop_get_encoder):
9771 Don't assume fixnum fits in int.
9772 * cmds.c (move_point): New function, that does the gist of
9773 Fforward_char and Fbackward_char, but does so while checking
9774 for integer overflow more accurately.
9775 (Fforward_char, Fbackward_char): Use it.
9776 (Fforward_line, Fend_of_line, internal_self_insert)
9777 (internal_self_insert):
9778 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

10559 2012-05-14 Glenn Morris <rgm@gnu.org>

10569 (report_error, report_error_1, make_hdr, copy_sym)
10570 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
10571 Make arguments const char *, not char *, to avoid violations of C
10572 standard and to fix some AIX warnings reported by Gilles Pion.
10574 2012-05-14 Eli Zaretskii <eliz@gnu.org>
10576 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
10577 already have overlays loaded.
10578 (handle_single_display_spec): Before returning without displaying
10579 fringe bitmap, synchronize the bidi iterator with the main display
10580 iterator, by calling iterate_out_of_display_property.
10581 (iterate_out_of_display_property): Detect buffer iteration by
10582 testing that it->string is a Lisp string.
10583 (get_next_display_element): When the current object is exhausted,
10584 and there's something on it->stack, call set_iterator_to_next to
10585 proceed with what's on the stack, instead of returning zero.
10586 (set_iterator_to_next): If called at the end of a Lisp string,
10587 proceed to consider_string_end without incrementing string
10588 position. Don't increment display vector index past the end of
10589 the display vector. (Bug#11417)
10590 (pos_visible_p): Don't report a position visible when move_it_to
10591 stopped at the last line of window, which happens to be scanned
10592 backwards by the bidi iteration. (Bug#11464)
10594 2012-05-14 Eli Zaretskii <eliz@gnu.org>
10596 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
10597 and right-margin display specs even if the spec is invalid or we
10598 are on a TTY, and thus unable to display on the fringes.
10599 That's because the text with the property will not be displayed anyway,
10600 so we need to signal to the caller that this is a "replacing"
10601 display spec. This fixes display when the spec is invalid or we
10604 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
10606 * unexaix.c (make_hdr): Fix typo in prototype.

10637 Update dependencies.
10639 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
10641 * xgselect.c (xg_select): Put maxfds+1 into a var.
10642 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
10644 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
10646 2012-05-10 Dave Abrahams <dave@boostpro.com>

10653 * dbusbind.c (xd_registered_buses): New internal Lisp object.
10654 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
10655 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
10656 Initialize xd_registered_buses.
10658 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
10660 Untag more efficiently if USE_LSB_TAG.
10661 This is based on a proposal by YAMAMOTO Mitsuharu in
10662 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
10663 For an admittedly artificial (nth 8000 longlist) benchmark on
10664 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
10665 Emacs's overall text size by 1%.
10666 * lisp.h (XUNTAG): New macro.
10667 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
10668 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
10669 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
10670 * eval.c (Fautoload):
10671 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
10672 * frame.h (XFRAME): Use XUNTAG.
10674 Port recent dbusbind.c changes to 32-bit --with-wide-int.
10675 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
10676 Remove unportable assumptions about print widths of types like
10678 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
10679 intptr_t when converting between pointer and integer, to avoid GCC
10680 warnings about wrong width.
10682 2012-05-09 Eli Zaretskii <eliz@gnu.org>
10684 * w32proc.c (new_child): Force Windows to reserve only 64KB of
10685 stack for each reader_thread, instead of defaulting to 8MB
10686 determined by the linker. This avoids failures in creating
10687 subprocesses on Windows 7, see the discussion in this thread:
10688 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
10690 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
10692 Fix up display of the *Minibuf-0* buffer in the mini window.
10693 * keyboard.c (read_char): Don't clear the echo area if there's no
10695 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
10696 contents of *Minibuf-0*) if there's no message displayed in its stead.
10698 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
10700 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
10703 2012-05-06 Chong Yidong <cyd@gnu.org>
10705 * lisp.mk (lisp): Update.
10707 2012-05-05 Jim Meyering <meyering@redhat.com>
10709 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
10711 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
10713 * data.c (PUT_ERROR): New macro.
10714 (syms_of_data): Use it. Add new error type `user-error'.
10715 * undo.c (user_error): New function.
10716 (Fprimitive_undo): Use it.
10717 * print.c (print_error_message): Adjust print style for `user-error'.
10718 * keyboard.c (user_error): New function.
10719 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
10721 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
10723 Do not limit current-time-string to years 1000..9999.
10724 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
10725 (Fcurrent_time_string): Support any year that is supported by the
10726 underlying localtime representation. Don't use asctime, as it
10727 has undefined behavior for years outside the range -999..9999.
10729 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
10731 Fix race conditions involving setenv, gmtime, localtime, asctime.
10732 Without this fix, interrupts could mess up code that uses these
10733 nonreentrant functions, since setting TZ invalidates existing
10734 tm_zone or tzname values, and since most of these functions return
10735 pointers to static storage.
10736 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
10737 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
10738 Grow the critical sections to include not just invoking
10739 localtime/gmtime, but also accessing these functions' results
10740 including their tm_zone values if any, and any related TZ setting.
10741 (format_time_string): Last arg is now struct tm *, not struct tm **,
10742 so that the struct tm is saved in the critical section.
10743 All callers changed. Simplify allocation of initial buffer, partly
10744 motivated by the fact that memory allocation needs to be outside
10745 the critical section.
10747 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
10749 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
10750 with RESET_INTERVAL.
10752 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
10753 Remove duplicated buffer name initialization.
10755 2012-05-02 Jim Meyering <jim@meyering.net>
10757 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
10759 * xfns.c (x_window): Use xstrdup (Bug#11375).
10761 2012-05-02 Eli Zaretskii <eliz@gnu.org>
10763 * xdisp.c (pos_visible_p): If already at a newline from the
10764 display string before the 'while' loop, don't walk back the glyphs
10765 from it3.glyph_row. Solves assertion violation when the display
10766 string begins with a newline (egg.el). (Bug#11367)
10768 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
10770 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
10773 2012-05-01 Glenn Morris <rgm@gnu.org>
10775 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
10776 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
10777 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
10778 All were removed before 23.1.
10780 * dispnew.c: Remove HAVE_LIBNCURSES test;
10781 it is always true on relevant platforms.
10783 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
10784 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
10786 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
10788 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
10790 * .gdbinit (xpr): Remove checks for no longer existing misc types.
10791 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
10794 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
10796 Do not avoid creating empty evaporating overlays (Bug#9642).
10797 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
10798 That is, do not delete an evaporating overlay if it becomes
10799 empty after its bounds are adjusted to fit within its buffer.
10800 This fix caused other problems, and I'm reverting it until we get
10801 to the bottom of them.
10803 2012-04-27 Chong Yidong <cyd@gnu.org>
10805 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
10807 2012-04-27 Eli Zaretskii <eliz@gnu.org>
10809 * xdisp.c (pos_visible_p): If the window start position is beyond
10810 ZV, start the display from buffer beginning. Prevents assertion
10811 violation in init_iterator when the minibuffer window is scrolled
10812 via the scroll bar.
10814 * window.c (window_scroll_pixel_based): Likewise.
10816 2012-04-27 Chong Yidong <cyd@gnu.org>
10818 * keymap.c (where_is_internal): Doc fix (Bug#10872).
10820 2012-04-27 Glenn Morris <rgm@gnu.org>
10822 * fileio.c (Fcopy_file, Fset_file_selinux_context):
10823 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
10825 2012-04-27 Eli Zaretskii <eliz@gnu.org>
10827 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
10828 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
10830 2012-04-26 Eli Zaretskii <eliz@gnu.org>
10832 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
10833 display element, check also the underlying string or buffer
10834 character. (Bug#11341)
10836 * w32menu.c: Include w32heap.h.
10837 (add_menu_item): If the call to AppendMenuW (via
10838 unicode_append_menu) fails, disable Unicode menus only if we are
10839 running on Windows 9X/Me.
10841 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
10843 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
10844 (xgetint): Add missing shift for LSB tags.
10846 2012-04-24 Martin Rudalics <rudalics@gmx.at>
10848 * keyboard.c (read_char): Don't wipe echo area for select window
10849 events: These might get delayed via `mouse-autoselect-window'
10852 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
10854 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
10855 manipulation of :loaded-from data.
10857 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
10859 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
10860 now a cons (bug#11311).
10862 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
10864 Do not create empty overlays with the evaporate property (Bug#9642).
10865 * buffer.c (Fmove_overlay): Delete an evaporating overlay
10866 if it becomes empty after its bounds are adjusted to fit within
10867 its buffer. Without this fix, in a nonempty buffer (let ((o
10868 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
10869 yields an empty overlay that has the evaporate property, which is
10870 not supposed to happen.
10872 Fix minor GTK3 problems found by static checking.
10873 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)

10882 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
10883 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)

10890 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
10892 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
10893 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
10894 (__malloc_size_t, __malloc_ptrdiff_t):
10895 Remove. All uses removed, replaced by the definiens if needed,
10896 since we can assume C89 or better now.
10897 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
10898 (protect_malloc_state, align, get_contiguous_space)

10905 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
10906 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
10907 Define using prototypes, not old style.
10908 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
10909 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.

10915 (valloc): Use getpagesize, not __getpagesize.
10916 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.

10972 * alloc.c: Handle unusual debugging option combinations.
10973 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
10974 since the two debugging options are incompatible.
10975 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
10977 (mem_init, mem_insert, mem_insert_fixup):
10978 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

10988 (list_system_processes, system_process_attributes) [__FreeBSD__]:
10989 Use Emacs indenting style more consistently. Avoid some casts.

11071 New extern decls, to avoid calling undeclared functions.
11072 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
11073 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined

11076 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
11077 Remove one incorrect comment and fix another.

11080 See http://lists.gnu.org/archive/html/emacs-devel/2011-12/msg00720.html
11081 * ralloc.c (ALIGNED, ROUND_TO_PAGE, HEAP_PTR_SIZE)
11082 (r_alloc_size_in_use, r_alloc_freeze, r_alloc_thaw): Remove; unused.
11083 (r_alloc_sbrk): Now static.

11086 See http://lists.gnu.org/archive/html/emacs-devel/2011-12/msg00720.html
11087 * buffer.c (ralloc_reset_variable, r_alloc, r_re_alloc)
11088 (r_alloc_free) [REL_ALLOC]: Move decls from here ...
11089 * lisp.h (r_alloc, r_alloc_free, r_re_alloc, r_alloc_reset_variable)

11091 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
11092 Remove decls. This fixes an "It stinks!".
11094 * alloc.c (which_symbols): Fix alignment issue / type clash.
11096 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
11098 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
11099 (struct Lisp_Misc_Any): Likewise.
11100 (struct Lisp_Free): Likewise.
11101 * alloc.c (union aligned_Lisp_Symbol): Define.
11102 (SYMBOL_BLOCK_SIZE, struct symbol_block): Use union
11103 aligned_Lisp_Symbol instead of struct Lisp_Symbol.

11109 2012-04-14 Paul Eggert <eggert@cs.ucla.edu>
11111 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
11112 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
11113 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
11114 * s/netbsd.h, s/sol2-6.h:
11115 Remove definition of GC_MARK_STACK, since the default now works.
11116 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
11117 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
11118 no longer the default.
11119 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
11121 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
11123 * lread.c (lisp_file_lexically_bound_p):
11124 Fix hang at ";-*-\n" (bug#11238).
11126 2012-04-14 Eli Zaretskii <eliz@gnu.org>
11128 * xdisp.c (find_last_unchanged_at_beg_row): Don't consider a row

11140 2012-04-13 Reuben Thomas <rrt@sc3d.org>
11142 * indent.c (Fmove_to_column): Change interactive spec (Bug#739).
11144 2012-04-11 Daniel Colascione <dancol@dancol.org>
11146 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
11147 against is gone. It's better to use vfork now so that when Cygwin
11148 gains a new, working vfork, we use it automatically (bug#10398).
11150 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

11168 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
11170 * w32.c (w32_delayed_load): Record the full path of the library
11171 being loaded (bug#10424).
11173 2012-04-09 Glenn Morris <rgm@gnu.org>
11175 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
11176 not just in the obarray, before snarfing them. (Bug#11036)
11178 * Makefile.in ($(leimdir)/leim-list.el):
11179 Pass EMACS rather than BUILT_EMACS.
11181 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
11183 * process.c (make_process):
11184 * process.h: Add integer `gnutls_handshakes_tried' member to

11191 (emacs_gnutls_read): Use new log functions,
11192 `gnutls_handshakes_tried' process member, and
11193 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
11194 attempts per process (connection).
11196 2012-04-09 Chong Yidong <cyd@gnu.org>
11198 * eval.c (Fuser_variable_p, user_variable_p_eh)
11199 (lisp_indirect_variable): Functions deleted.
11200 (Fdefvar): Caller changed.
11202 * callint.c (Finteractive, Fcall_interactively):
11203 * minibuf.c (Fread_variable): Callers changed.
11205 2012-04-09 Eli Zaretskii <eliz@gnu.org>
11207 * xdisp.c (set_cursor_from_row): If the display string appears in
11208 the buffer at position that is closer to point than the position
11209 after the display string, display the cursor on the first glyph of
11210 the display string. Fixes cursor display when a 'display' text
11211 property immediately follows invisible text. (Bug#11094)
11213 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
11215 composite.c: use 'double' consistently
11216 * composite.c (get_composition_id): Use 'double' consistently
11217 instead of converting 'float' to 'double' and vice versa; this is
11218 easier to understand and avoids a GCC warning.
11220 2012-04-09 Glenn Morris <rgm@gnu.org>
11222 * Makefile.in: Generate leim-list with bootstrap-emacs, in
11223 preparation for dumping it with emacs. (Bug#4789)
11224 (leimdir): New variable.
11225 ($(leimdir)/leim-list.el): New rule.
11226 (emacs$(EXEEXT)): Depend on leim-list.el.

11242 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
11244 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
11245 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
11246 (mark_memory): Mark Lisp_Objects only if pointers might hide in
11247 objects, as mark_maybe_pointer will catch them otherwise.
11248 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
11249 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.

11256 2012-04-07 Eli Zaretskii <eliz@gnu.org>
11258 Support building on MS-Windows with libxml2.
11260 * makefile.w32-in (OBJ2): Add xml.$(O).
11261 (GLOBAL_SOURCES): Add xml.c.
11262 ($(BLD)/xml.$(O)): New dependency list.
11264 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
11265 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
11266 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
11267 [!WINDOWSNT]: New macros.
11268 (init_libxml2_functions, libxml2_loaded_p): New functions.
11269 (parse_region): Call fn_xmlCheckVersion instead of using the macro
11270 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
11271 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
11272 Calls xmlCleanupParser only if libxml2 was loaded (or statically
11274 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
11275 Call init_libxml2_functions before calling libxml2 functions.
11276 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
11278 * emacs.c: Don't include libxml/parser.h.
11279 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
11280 xmlCleanupParser directly.
11282 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
11284 2012-04-07 Eli Zaretskii <eliz@gnu.org>
11286 * indent.c (Fvertical_motion): If there is a display string at
11287 point, use it.vpos to compute how many lines to backtrack after
11288 move_it_to point. (Bug#11133)
11290 2012-04-06 Eli Zaretskii <eliz@gnu.org>
11292 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
11293 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
11294 about subtle differences between FETCH_CHAR* and STRING_CHAR*
11295 macros related to unification of CJK characters. For the details,
11296 see the discussion following the message here:
11297 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
11299 2012-04-04 Chong Yidong <cyd@gnu.org>
11301 * keyboard.c (Vdelayed_warnings_list): Doc fix.
11303 2012-04-01 Eli Zaretskii <eliz@gnu.org>
11305 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA

11313 2012-03-31 Eli Zaretskii <eliz@gnu.org>
11315 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
11316 position we get to after a call to move_it_to fails the
11317 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
11318 only if we wind up in a string from display property. (Bug#11063)
11320 * window.c (Fdelete_other_windows_internal): Invalidate the row
11321 and column information about mouse highlight, so that redisplay
11322 restores it after reallocating the glyph matrices. (Bug#7464)
11324 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
11325 string comes from a `display' text property, use the buffer
11326 position of that property as if we actually saw that position in
11328 (move_it_by_lines): Remove the assertion that
11329 "it->current_x == 0 && it->hpos == 0" which can be legitimately
11330 violated when there's a before-string at the beginning of a line.
11333 2012-03-30 Eli Zaretskii <eliz@gnu.org>
11335 * xdisp.c (append_space_for_newline): If the default face was

11337 (extend_face_to_end_of_line): Use the remapped default face for
11338 extending the face to the end of the line.
11339 (display_line): Call extend_face_to_end_of_line when the default
11340 face was remapped. (Bug#11068)
11342 2012-03-29 Eli Zaretskii <eliz@gnu.org>
11344 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
11346 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
11348 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
11350 2012-03-27 Glenn Morris <rgm@gnu.org>

11362 * keyboard.c (Vselection_inhibit_update_commands): New variable.
11363 (command_loop_1): Use it; inhibit selection update for

11370 2012-03-25 Kenichi Handa <handa@m17n.org>
11372 * dispextern.h (struct glyph): Change the bit length of
11373 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
11375 2012-03-24 Eli Zaretskii <eliz@gnu.org>
11377 * s/ms-w32.h (tzname): Include time.h before redirecting to

11382 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
11385 * xterm.c (XTread_socket): Only modify handling_signal if
11386 !SYNC_INPUT. (Bug#11080)
11388 2012-03-23 Eli Zaretskii <eliz@gnu.org>
11390 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
11391 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
11392 when fetching a multibyte character consumes more bytes than
11393 CHAR_BYTES returns, due to unification of CJK characters in
11394 string_char. (Bug#11073)
11396 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
11398 * process.c (wait_reading_process_output): Handle pty disconnect
11399 by refraining from sending oneself a SIGCHLD (bug#10933).
11401 2012-03-22 Chong Yidong <cyd@gnu.org>
11403 * dispextern.h (struct it): New member string_from_prefix_prop_p.
11405 * xdisp.c (push_prefix_prop): Rename from push_display_prop.

11433 that is not from display property, accept the row as a "cursor
11434 row" if one of the string's character has a non-nil `cursor'
11435 property. Fixes cursor positioning when there are newlines in
11436 overlay strings, e.g. in icomplete.el. (Bug#11035)
11438 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
11440 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
11442 2012-03-12 Chong Yidong <cyd@gnu.org>
11444 * eval.c (inhibit_lisp_code): Rename from
11445 inhibit_window_configuration_change_hook; move from window.c.
11447 * xfns.c (unwind_create_frame_1, Fx_create_frame):
11448 * window.c (run_window_configuration_change_hook)
11449 (syms_of_window): Callers changed.
11451 2012-03-11 Chong Yidong <cyd@gnu.org>

11464 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
11466 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
11468 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
11469 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
11472 2012-03-03 Glenn Morris <rgm@gnu.org>
11474 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
11476 2012-03-02 Eli Zaretskii <eliz@gnu.org>

11479 position past the first glyph_row that ends at ZV. (Bug#10902)
11480 (redisplay_window, next_element_from_string): Fix typos in
11482 (redisplay_window): Pass to move_it_vertically the margin in
11483 pixels, not in screen lines.
11485 2012-03-02 Glenn Morris <rgm@gnu.org>
11487 * buffer.c (buffer-list-update-hook): Doc fix.
11489 2012-02-29 Eli Zaretskii <eliz@gnu.org>
11491 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
11492 push_it before setting up the iterator for the first overlay
11493 string, even if we have an empty string loaded.
11494 (next_overlay_string): If there's an empty string on the iterator
11495 stack, pop the stack. (Bug#10903)
11497 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
11499 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
11500 Suggested by Stefan Monnier in
11501 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
11502 * alloc.c (widen_to_Lisp_Object): New static function.
11503 (mark_memory): Also mark Lisp_Objects by fetching pointer words
11504 and widening them to Lisp_Objects. This would work even if
11505 USE_LSB_TAG is defined and wide integers are used, which might
11506 happen in a future version of Emacs.
11508 2012-02-25 Chong Yidong <cyd@gnu.org>
11510 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):

11547 when computing $valmask.
11549 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
11550 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
11551 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
11552 It's useless in that case, and it can cause problems on hosts
11553 that allocate halves of EMACS_INT values separately.
11554 Reported by Dan Horák. Diagnosed by Andreas Schwab in
11555 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
11556 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
11557 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
11558 it avoids undefined behavior on hosts where shifting right by more
11559 than the word width has undefined behavior.

12176 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
12177 verifies glyph row's hash code--we have just reallocated the

12343 is set, removing the need for VIRT_ADDRESS_VARIES.
12344 (PURE_P): Use a more-efficient implementation that needs just one

12361 behave as if the cursor position were at the window margin.
12363 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
12364 and the cursor position is out of bounds, behave as if the cursor
12365 position were at the window margin. (Bug#10075)
12367 2011-11-18 Chong Yidong <cyd@gnu.org>
12369 * window.c (Fwindow_combination_limit): Make first argument

12391 compute_line_metrics.
12392 (compute_line_metrics): Call row_hash, instead of computing the
12395 * dispnew.c (verify_row_hash): Call row_hash for computing the
12396 hash code of a row, instead of duplicating code from xdisp.c.
12398 * dispextern.h (row_hash): Add prototype.
12400 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>

12506 The trivial performance wins aren't worth the portability hassles; see
12507 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
12509 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
12510 (window_box_width, window_box_left, window_box_left_offset)
12511 (window_box_right, window_box_right_offset): Undo previous change,
12512 by removing the "extern"s.
12513 * intervals.c (adjust_intervals_for_insertion)
12514 (adjust_intervals_for_deletion): Undo previous change,
12515 making these static again.
12516 (offset_intervals, temp_set_point_both, temp_set_point)
12517 (copy_intervals_to_string): No longer inline.
12518 * xdisp.c (window_text_bottom_y, window_box_width)
12519 (window_box_height, window_box_left_offset)
12520 (window_box_right_offset, window_box_left, window_box_right)
12521 (window_box): No longer inline.

12531 2011-11-07 Juanma Barranquero <lekktu@gmail.com>
12533 * lisp.h (syms_of_abbrev): Remove declaration.
12534 Reported by CHENG Gao <chenggao@royau.me>.
12536 2011-11-07 Eli Zaretskii <eliz@gnu.org>
12538 * w32.c (check_windows_init_file): Don't look for term/w32-win.el
12539 if Vpurify_flag is non-nil. Fixes a crash when running w32 build
12540 of temacs in GUI mode.
12542 2011-11-07 Martin Rudalics <rudalics@gmx.at>
12544 * window.h: Declare delete_all_child_windows instead of
12545 delete_all_subwindows.
12546 * window.c (Fwindow_nest, Fset_window_nest)
12547 (Fset_window_new_total, Fset_window_new_normal)
12548 (Fwindow_resize_apply): Don't use term subwindow in doc-strings.
12549 (delete_all_subwindows): Rename to delete_all_child_windows.
12550 (Fdelete_other_windows_internal, Fset_window_configuration):
12551 Call delete_all_child_windows instead of delete_all_subwindows.
12552 * frame.c (delete_frame): Call delete_all_child_windows instead
12553 of delete_all_subwindows.
12555 2011-11-07 Paul Eggert <eggert@cs.ucla.edu>
12557 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
12558 This is also needed for porting to any host where GC_MARK_STACK is
12559 not GC_MAKE_GCPROS_NOOPS.
12560 (which_symbols): Use it.
12562 2011-11-07 Kenichi Handa <handa@m17n.org>
12564 * coding.c (coding_set_destination): Check coding->src_pos only
12565 when coding->src_object is a buffer (bug#9910).

12575 * xmenu.c (cleanup_widget_value_tree): New function.
12576 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
12577 calling free_menubar_widget_value_tree directly (Bug#9830).
12579 2011-11-06 Paul Eggert <eggert@cs.ucla.edu>
12581 Fix some portability problems with 'inline'.
12582 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
12583 (window_box_width, window_box_left, window_box_left_offset)
12584 (window_box_right, window_box_right_offset): Declare extern.
12585 Otherwise, these inline functions do not conform to C99 and
12586 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
12587 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
12588 * intervals.c (adjust_intervals_for_insertion)
12589 (adjust_intervals_for_deletion): Now extern, because otherwise the
12590 extern inline functions 'offset_intervals' couldn't refer to it.
12591 (static_offset_intervals): Remove.
12592 (offset_intervals): Rewrite using the old contents of
12593 static_offset_intervals. The old version didn't conform to C99
12594 because an extern inline function contained a reference to an
12595 identifier with static linkage.
12597 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
12599 * keyboard.c (interrupt_signal): Don't call kill-emacs while in

12604 * xdisp.c (init_iterator, reseat_to_string): Don't set the
12605 iterator's bidi_p flag if Vpurify_flag is non-nil. (Bug#9963)
12606 (Fcurrent_bidi_paragraph_direction): If Vpurify_flag is non-nil,
12607 return Qleft_to_right.
12609 2011-11-06 Chong Yidong <cyd@gnu.org>

12612 (Fminibuffer_window, Fwindow_buffer, Fwindow_splits)
12613 (Fset_window_splits, Fwindow_nest, Fset_window_nest)
12614 (Fwindow_use_time, Fwindow_total_size, Fwindow_normal_size)
12615 (Fwindow_new_normal, Fwindow_left_column, Fwindow_top_line)
12616 (Fwindow_margins, Fwindow_fringes, Fwindow_scroll_bars)
12617 (Fwindow_vscroll): Doc fix.
12618 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
12619 argument, since it makes no sense to pass a live window and for
12620 consistency with window-child.

12648 (unwind_create_frame): New function (Bug#9943).
12649 (Fx_create_frame): Restructure code to be more similar to the one in
12650 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).
12651 Initialize image_cache_refcount if GLYPH_DEBUG (Bug#9943).
12652 Move terminal->reference_count++ just before making the frame official
12655 * nsterm.m (x_free_frame_resources): New function.
12656 (x_destroy_window): Move code to x_free_frame_resources.
12658 * xfns.c (unwind_create_frame): Fix comment.

12660 Move terminal->reference_count++ just before making the frame
12661 official. Move initialization of image_cache_refcount and
12662 dpyinfo_refcount before calling init_frame_faces (Bug#9943).
12664 2011-11-05 Eli Zaretskii <eliz@gnu.org>
12666 Support MSVC build with newer versions of Visual Studio.

12703 the beginning or the end of the buffer. (Bug#9955)
12705 2011-11-04 Jan Djärv <jan.h.d@swipnet.se>
12707 * gtkutil.c (xg_make_tool_item): Add callbacks if one of wimage or

12830 (w32font_open_internal, compute_metrics):
12831 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
12832 instead of calling the "wide" APIs directly.

12907 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
12908 * editfns.c: Rewrite current-time-zone so that it invokes
12909 the equivalent of (format-time-string "%Z") to get the time zone name.
12910 This fixes a bug when the time zone name contains characters that
12911 need converting from the system time locale to Emacs internal format.
12912 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
12913 that patch fixed format-time-string to do the conversion, but
12914 I forgot to fix current-time-zone.
12915 (format_time_string): New function, containing most of
12916 what Fformat_time_string used to contain.
12917 (Fformat_time_string): Rewrite in terms of format_time_string.
12918 This doesn't change this function's behavior.
12919 (current-time-zone): Rewrite to use format_time_string.
12920 This fixes the bug reported by Michael Schierl in
12921 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
12922 Jason Rumney's 2007-06-07 change worked around this bug, but
12924 * systime.h (tzname, timezone): Remove no-longer-used declarations.
12926 2011-10-19 Eli Zaretskii <eliz@gnu.org>
12928 * xdisp.c (start_display): If the character at POS is displayed
12929 via a display vector, reset IT->current.dpvec_index to zero.
12930 (try_window_reusing_current_matrix): If a line ends in a display
12931 vector or the next line starts in a display vector, continue
12932 redrawing the window even though the character position of
12933 start_row was reached.
12936 2011-10-18 Chong Yidong <cyd@gnu.org>
12938 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
12939 with nobreak-char-display too.
12941 2011-10-18 Eli Zaretskii <eliz@gnu.org>
12943 Fix part 3 of bug#9771.
12944 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
12945 (bidi_resolve_neutral): Don't enter the expensive loop looking for
12946 non-neutral characters if the current character is a paragraph
12947 separator (a.k.a. Newline). This avoids running the same
12948 expensive loop twice, once when we consume the preceding newline
12949 and the other time when the line actually needs to be displayed.
12950 Avoid the loop when we see neutrals on the base embedding level
12951 following a character whose directionality is the same as the
12952 paragraph's. This avoids running the expensive loop when a line
12953 ends in a long sequence of neutrals, like control characters.
12954 Add assertion against STRONG_AL type. Slightly rearrange code
12955 that determines the type of a neutral given the first non-neutral
12957 (bidi_level_of_next_char): Set next_en_pos to zero when
12958 invalidating its info.
12960 2011-10-17 Eli Zaretskii <eliz@gnu.org>
12962 * xdisp.c (push_display_prop): Determine whether to record string
12963 or buffer position by IT->string, not by IT->method. Allow
12964 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
12965 (move_it_vertically_backward): Don't look for character position
12966 immediately after the newline when in a continuation line.
12969 2011-10-15 Martin Rudalics <rudalics@gmx.at>
12971 * window.c (coordinates_in_window): Rewrite and delabelize
12972 vertical border check. (Bug#5357) (Bug#9618)
12974 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
12976 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
12977 errors in XSetWindowBorder (bug#9310).
12979 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
12981 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
12982 avoid crash when xmalloc overrun checking is enabled.
12984 2011-10-13 Eli Zaretskii <eliz@gnu.org>
12986 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
12987 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
12988 cursor motion with <left> and <right> arrow keys.
12990 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
12991 some callers set that themselves.
12993 2011-10-12 Eli Zaretskii <eliz@gnu.org>
12995 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
12996 display string and the previous row comes from the same string and
12997 is empty. (Bug#9739) (Bug#9738)
12999 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
13001 * doc.c (get_doc_string): Encode file name (bug#9735).
13003 2011-10-12 Eli Zaretskii <eliz@gnu.org>
13005 * bidi.c (bidi_level_of_next_char):
13006 * xdisp.c (get_visually_first_element): Remove old incorrect
13007 comments regarding the Unicode Line Separator character.
13009 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
13011 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
13013 * alloc.c (Fgc_status): Do not access beyond zombies array
13014 boundary if nzombies > MAX_ZOMBIES.
13015 * alloc.c (dump_zombies): Add missing format specifier.
13017 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
13019 * xdisp.c (set_cursor_from_row): Simplify conditionals,
13020 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
13022 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
13023 Some packages use them to denote characters with modifiers.
13025 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
13027 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
13028 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
13029 matching a pp-number. Rename parameter var to var1.
13031 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
13033 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
13035 2011-10-08 Glenn Morris <rgm@gnu.org>
13037 * callint.c (Fcall_interactively): Give a more explicit error for the
13038 'c' case with a non-character input. (Bug#8479)
13040 2011-10-08 Eli Zaretskii <eliz@gnu.org>
13042 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
13044 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
13045 lines that are hscrolled on the left.
13047 * dispnew.c (buffer_posn_from_coords): Account for a possible
13048 presence of header-line. (Bug#4426)
13050 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
13052 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
13053 Don't advertise functionality which we discourage or doesn't work.
13055 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
13057 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
13058 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
13059 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
13060 this makes Emacs dump core during garbage collection on rare
13061 occasions. sizeof is obviously inferior to offsetof here, so
13062 stick with offsetof.
13063 (GC_POINTER_ALIGNMENT): New macro.
13064 (mark_memory): Omit 3rd (offset) arg; caller changed.
13065 Don't assume EMACS_INT alignment is the same as pointer alignment.
13067 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
13069 * keyboard.c (read_key_sequence_remapped): New var.
13070 (read_key_sequence): Compute remapping in the right buffer.
13071 (command_loop_1): Use read_key_sequence's remapping directly.
13073 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
13075 * dired.c (file_name_completion): Don't expand file name.
13076 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
13077 before checking file name handler.
13079 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
13080 they've been requested explicitly (bug#9591).
13082 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
13084 * keymap.c (Fsingle_key_description): Use make_specified_string
13085 instead of build_string to build string from push_key_description.
13088 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
13090 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
13091 This fixes a Y2038 bug on 64-bit hosts.
13092 * buffer.c (reset_buffer):
13093 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
13094 (Fclear_buffer_auto_save_failure):
13095 Use 0, not -1, to represent an unset failure time, since time_t
13096 might not be signed.
13098 Remove dependency on glibc malloc internals.
13099 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13100 Move back here from lisp.h, but with their new implementations.
13101 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13102 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
13103 * charset.c (charset_table_init): New static var.
13104 (syms_of_charset): Use it instead of xmalloc. This removes a
13105 dependency on glibc malloc internals. See Eli Zaretskii's comment in
13106 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
13107 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13108 Move back to alloc.c.
13109 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13110 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
13112 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
13114 * nsterm.m (windowDidResize): Call x_set_window_size only when
13115 ns_in_resize is true. Otherwise set pixelwidth/height and
13116 call change_frame_size (Bug#9628).
13118 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
13120 Port --enable-checking=all to Fedora 14 x86-64.
13121 * charset.c (syms_of_charset): Also account for glibc malloc's
13122 internal overhead when calculating the initial malloc maximum.
13124 Port --enable-checking=all to Fedora 14 x86.
13125 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13127 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
13128 (overrun_check_realloc, overrun_check_free):
13129 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
13130 That way, xmalloc returns a properly-aligned pointer even if
13131 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
13132 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
13133 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
13134 into account when calculating the initial malloc maximum.
13135 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13136 Move here from alloc.c, so that charset.c can use it too.
13137 Properly align; the old code wasn't right for common 32-bit hosts
13138 when configured with --enable-checking=all.
13139 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13140 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
13142 2011-09-29 Eli Zaretskii <eliz@gnu.org>
13144 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
13147 2011-09-28 Eli Zaretskii <eliz@gnu.org>
13149 * xdisp.c (compute_display_string_end): If there's no display
13150 string at CHARPOS, return -1.
13152 * bidi.c (bidi_fetch_char): When compute_display_string_end
13153 returns a negative value, treat the character as a normal
13154 character not covered by a display string. (Bug#9624)
13156 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
13158 * lread.c (Fread_from_string): Fix typo in docstring.
13160 2011-09-27 Eli Zaretskii <eliz@gnu.org>
13162 * xdisp.c (handle_invisible_prop): If invisible text ends on a
13163 newline, reseat the iterator instead of bidi-iterating there one
13164 character at a time. (Bug#9610)
13165 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
13166 TO_CHARPOS if the bidi iterator is at base embedding level.
13168 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
13170 * lread.c (readevalloop): Use correct code for NBSP.
13171 (read1): Likewise. (Bug#9608)
13173 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
13175 * dbusbind.c (Fdbus_register_signal): When service is not
13176 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
13178 2011-09-25 Glenn Morris <rgm@gnu.org>
13180 * buffer.c (truncate-lines): Doc fix.
13182 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
13184 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
13185 (Fset_window_next_buffers): Doc fix.
13187 2011-09-24 Glenn Morris <rgm@gnu.org>
13189 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
13191 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
13193 Fix minor problems found by static checking.
13194 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
13195 * indent.c (Fvertical_motion): Fix == vs = typo.
13197 2011-09-24 Eli Zaretskii <eliz@gnu.org>
13199 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
13200 Default value is now t. Doc fix.
13202 * indent.c (Fvertical_motion): Compute and apply the overshoot
13203 logic when moving up, not only when moving down. Fix the
13204 confusing name and values of the it_overshoot_expected variable;
13205 logic changes accordingly. (Bug#9254) (Bug#9549)
13207 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
13208 CHARPOS is covered by a display string which includes newlines.
13209 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
13210 is covered by a display string with embedded newlines.
13212 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
13214 * dbusbind.c (Fdbus_register_signal): Add match rule to
13215 Vdbus_registered_objects_table. (Bug#9581)
13216 (Fdbus_register_method, Vdbus_registered_objects_table):
13219 2011-09-24 Jim Meyering <meyering@redhat.com>
13221 do not ignore write error for any output size
13222 The previous change was incomplete.
13223 While it makes emacs --batch detect the vast majority of stdout
13224 write failures, errors were still ignored whenever the output size is
13225 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
13226 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
13227 && echo FAIL: ignored write error
13228 FAIL: ignored write error
13229 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
13230 && echo FAIL: ignored write error
13231 FAIL: ignored write error
13232 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
13234 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
13236 * emacs.c (Fkill_emacs): In noninteractive mode exit
13237 non-successfully if a write error occurred on stdout. (Bug#9574)
13239 2011-09-21 Eli Zaretskii <eliz@gnu.org>
13241 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
13244 * dispextern.h (struct it): Update the comment documenting what
13247 2011-09-20 Eli Zaretskii <eliz@gnu.org>
13249 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
13250 a display string, extend search for cursor position to end of row.
13251 (find_row_edges): If the row ends in a newline from a display
13252 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
13253 Handle the case of a display string with multiple newlines.
13254 (Fcurrent_bidi_paragraph_direction): Fix search for previous
13255 non-empty line. Fixes confusing cursor motion with arrow keys at
13256 the beginning of a line that starts with whitespace.
13258 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
13260 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
13263 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
13265 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
13266 boolean (Bug#9154).
13268 2011-09-18 Eli Zaretskii <eliz@gnu.org>
13270 * xdisp.c (display_line): Record maximum and minimum buffer
13271 positions even if no glyphs were produced (e.g., by a zero-width
13272 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
13273 buffer positions that will be removed from the glyph row because
13275 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
13276 column is beyond frame width: don't subtract 1 "pixel" when
13277 computing width of the stretch.
13278 (reseat_at_next_visible_line_start): Undo the change made on
13279 2011-09-17 that saved paragraph information and restored it after
13280 the call to `reseat'. (Bug#9545)
13282 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
13284 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
13285 and turn window cursor on if cleared (Bug#9415).
13287 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
13289 * search.c (boyer_moore): Take unibyte characters from pattern
13290 literally. (Bug#9458)
13292 2011-09-18 Eli Zaretskii <eliz@gnu.org>
13294 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
13296 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
13298 Fix minor problem found by static checking.
13299 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
13300 initialized, to pacify gcc -Wuninitialized.
13302 * fileio.c: Report proper errno when syscall falls.
13303 (Finsert_file_contents): Save and restore errno,
13304 so that report_file_error outputs the correct diagnostic.
13305 (Fwrite_region) [CLASH_DETECTION]: Likewise.
13307 2011-09-18 Eli Zaretskii <eliz@gnu.org>
13309 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
13311 2011-09-17 Eli Zaretskii <eliz@gnu.org>
13313 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
13314 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
13316 2011-09-17 Eli Zaretskii <eliz@gnu.org>
13318 * xdisp.c (reseat_at_next_visible_line_start): Keep information
13319 about the current paragraph and restore it after the call to reseat.
13321 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
13322 (bidi_find_paragraph_start): Search back for paragraph beginning
13323 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
13324 (bidi_move_to_visually_next): Only trigger paragraph-related
13325 computations when the last character is a newline or at EOB, not
13326 just any NEUTRAL_B. (Bug#9470)
13328 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
13329 truncated lines if point is covered by a display string. (Bug#9524)
13331 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
13333 * xselect.c: Relax test for outgoing X longs (Bug#9498).
13334 (cons_to_x_long): New function.
13335 (lisp_data_to_selection_data): Use it. Correct the test for
13336 short-versus-long data; it was negated. Break out of vector
13337 loop, for efficiency, when a long datum is discovered.
13339 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
13341 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
13343 2011-09-16 Eli Zaretskii <eliz@gnu.org>
13345 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
13346 GCC PR/17406) by declaring this function with external scope.
13348 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
13350 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).

13355 * editfns.c (Fformat): Correctly handle text properties on "%%".
13357 2011-09-15 Eli Zaretskii <eliz@gnu.org>
13359 * xterm.c (x_draw_composite_glyph_string_foreground):

13361 * term.c (encode_terminal_code):
13362 * composite.c (composition_update_it, get_composition_id):
13363 * xdisp.c (get_next_display_element)
13364 (fill_composite_glyph_string): Add comments about special meaning
13365 of TAB characters in a composition.
13367 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
13369 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
13370 This occurs when processing a multibyte format.
13371 Problem reported by Wolfgang Jenker.
13373 2011-09-15 Johan Bockgård <bojohan@gnu.org>
13375 * xdisp.c (try_cursor_movement): Only check for exact match if
13376 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
13378 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
13380 Remove unused external symbols.
13381 * dispextern.h (calc_pixel_width_or_height): Remove decl.
13382 * xdisp.c (calc_pixel_width_or_height): Now static.
13383 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
13384 * indent.c (check_display_width):
13385 * w32term.c: Fix comment to match code.
13386 * xterm.c, xterm.h (x_catching_errors): Remove.
13388 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
13390 * xselect.c: Use signed conversions more consistently (Bug#9498).
13391 (selection_data_to_lisp_data): Assume incoming selection data are
13392 signed integers, not unsigned. This is to be consistent with
13393 outgoing selection data, which was modified to use signed integers
13394 in as part of the fix to Bug#9196 in response to Jan D.'s comment
13395 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
13396 expects long, not unsigned long.

13400 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
13401 computation of loop end. Reported by Johan Bockgård
13404 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
13406 * frame.c (Fother_visible_frames_p): Function deleted.
13408 2011-09-12 Eli Zaretskii <eliz@gnu.org>
13410 * indent.c (compute_motion): Process display vector front to back
13411 rather than the other way around. (Bug#2496)
13413 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
13415 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
13417 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
13419 * minibuf.c (Fread_from_minibuffer): Doc fix.
13421 2011-09-11 Eli Zaretskii <eliz@gnu.org>
13423 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
13424 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
13426 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
13428 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
13429 value for non-existent files.
13431 2011-09-11 Eli Zaretskii <eliz@gnu.org>
13433 * fileio.c (Finsert_file_contents): If the file cannot be opened,
13434 set its "size" to -1. This will set the modtime_size field of
13435 the corresponding buffer to -1, which is what
13436 verify-visited-file-modtime expects for files that do not exist.
13439 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
13441 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
13443 * lisp.h: ... from here. push_key_description is no longer
13444 defined in keyboard.c, so its declaration should not be in
13445 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
13446 logically belongs with push_key_description.
13448 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
13450 * buffer.h: Include <sys/types.h> instead of <time.h>.
13451 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
13452 Problem reported by Herbert J. Skuhra.
13454 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
13456 * xml.c (parse_region): Make the parsing work for
13457 non-comment-starting XML files again (bug#9144).
13459 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
13461 * image.c (gif_load): Fix calculation of bottom and right corner.
13464 2011-09-10 Eli Zaretskii <eliz@gnu.org>
13466 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
13467 redisplay in small windows.
13469 2011-09-09 Eli Zaretskii <eliz@gnu.org>
13471 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
13473 2011-09-08 Martin Rudalics <rudalics@gmx.at>
13475 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
13476 Operate on live windows only.
13478 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
13480 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
13482 2011-09-07 Eli Zaretskii <eliz@gnu.org>
13484 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
13485 only under bidi iteration.
13487 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
13489 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
13491 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13493 isnan: Fix porting problem to Solaris 10 with bundled gcc.
13494 Without this fix, the command to link temacs failed due to an
13495 undefined symbol __builtin_isnan. This is because
13496 /usr/include/iso/math_c99.h #defines isnan(x) to
13497 __builtin_isnan(x), but the bundled gcc, which identifies itself
13498 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
13500 * floatfns.c (isnan): #undef, and then #define to a clone of
13502 (Fisnan): Always define, since it's always available now.
13503 (syms_of_floatfns): Always define isnan at the Lisp level.
13505 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13507 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
13509 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13511 * fileio.c: Fix bugs with large file offsets (Bug#9428).
13512 The previous code assumed that file offsets (off_t values) fit in
13513 EMACS_INT variables, which is not true on typical 32-bit hosts.
13514 The code messed up by falsely reporting buffer overflow in cases
13515 such as (insert-file-contents "big" nil 1 2) into an empty buffer
13516 when "big" contains more than 2**29 bytes, even though this
13517 inserts just one byte and does not overflow the buffer.
13518 (Finsert_file_contents): Store file offsets as off_t
13519 values, not as EMACS_INT values. Check for overflow when
13520 converting between EMACS_INT and off_t. When checking for
13521 buffer overflow or for overlap, take the offsets into account.
13522 Don't use EMACS_INT for small values where int suffices.
13523 When checking for overlap, fix a typo: ZV was used where
13524 ZV_BYTE was intended.
13525 (Fwrite_region): Don't assume off_t fits into 'long'.
13526 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
13528 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
13530 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
13532 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
13534 sprintf-related integer and memory overflow issues (Bug#9412).
13536 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
13537 (esprintf, exprintf, evxprintf): New functions.
13538 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
13539 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
13540 (modify_event_symbol): Do not assume that the length of
13541 name_alist_or_stem is safe to alloca and fits in int.
13542 (Fexecute_extended_command): Likewise for function name and binding.
13543 (Frecursion_depth): Wrap around reliably on integer overflow.
13544 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
13545 since some callers pass EMACS_INT values.
13546 (Fsingle_key_description): Don't crash if symbol name contains more
13547 than MAX_ALLOCA bytes.
13548 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
13549 (get_minibuffer): Arg is now EMACS_INT, not int.
13550 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
13551 (esprintf, exprintf, evxprintf): New decls.
13552 * window.h (command_loop_level, minibuf_level): Reflect API changes.
13554 * dbusbind.c (signature_cat): New function.
13555 (xd_signature, Fdbus_register_signal):
13556 Do not overrun buffer; instead, report string overflow.
13558 * dispnew.c (add_window_display_history): Don't overrun buffer.
13559 Truncate instead; this is OK since it's just a log.
13561 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
13562 even if the time zone offset is outlandishly large.
13563 Don't mishandle offset == INT_MIN.
13565 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
13566 when creating daemon; the previous buffer-overflow check was incorrect.
13568 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
13569 which has the guts of the old verror function.
13571 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
13572 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
13574 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
13575 (font_unparse_xlfd): Don't blindly alloca long strings.
13576 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
13577 fits in int, when using sprintf. Use single snprintf to count
13578 length of string rather than counting it via multiple sprintfs;
13579 that's simpler and more reliable.
13580 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
13581 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
13582 sprintf, in case result does not fit in int.
13584 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
13585 (fontset_from_font): Print it.
13587 * frame.c (tty_frame_count): Now printmax_t, not int.
13588 (make_terminal_frame, set_term_frame_name): Print it.
13589 (x_report_frame_params): In X, window IDs are unsigned long,
13590 not signed long, so print them as unsigned.
13591 (validate_x_resource_name): Check for implausibly long names,
13592 and don't assume name length fits in 'int'.
13593 (x_get_resource_string): Don't blindly alloca invocation name;
13594 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
13597 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
13598 (xg_check_special_colors, xg_set_geometry):
13599 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
13601 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
13602 Use esprintf, not sprintf, in case result does not fit in int.
13604 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
13605 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
13606 it as a large positive number.
13607 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
13608 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
13610 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
13611 in case result does not fit in int.
13613 * print.c (float_to_string): Detect width overflow more reliably.
13614 (print_object): Make sprintf buffer a bit bigger, to avoid potential
13615 buffer overrun. Don't assume list length fits in 'int'. Treat
13616 print length of 0 as 0, not as infinity; to be consistent with other
13617 uses of print length in this function. Don't overflow print length
13618 index. Don't assume hash table size fits in 'long', or that
13619 vectorlike size fits in 'unsigned long'.
13621 * process.c (make_process): Use printmax_t, not int, to format
13622 process-name gensyms.
13624 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
13626 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
13627 to avoid potential buffer overrun.
13629 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
13630 if X resource line is longer than 512 bytes.
13632 * xfns.c (x_window): Make sprintf buffer a bit bigger
13633 to avoid potential buffer overrun.
13635 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
13637 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
13639 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
13641 Integer overflow fixes for scrolling, etc.
13642 Without these, Emacs silently mishandles large integers sometimes.
13643 For example, "C-u 4294967297 M-x recenter" was treated as if
13644 it were "C-u 1 M-x recenter" on a typical 64-bit host.
13646 * xdisp.c (try_window_id): Check Emacs fixnum range before
13647 converting to 'int'.
13649 * window.c (window_scroll_line_based, Frecenter):
13650 Check that an Emacs fixnum is in range before assigning it to 'int'.
13651 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
13652 values converted from Emacs fixnums.
13653 (Frecenter): Don't wrap around a line count if it is out of 'int'
13654 range; instead, treat it as an extreme value.
13655 (Fset_window_configuration, compare_window_configurations):
13656 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
13658 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
13659 that can exceed INT_MAX. Check that EMACS_INT value is in range
13660 before assigning it to the (possibly-narrower) index.
13661 (match_limit): Don't assume that a fixnum can fit in 'int'.
13663 * print.c (print_object): Use ptrdiff_t, not int, for index that can
13666 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
13667 (Fvertical_motion): Don't wrap around LINES values that don't fit
13668 in 'int'. Instead, treat them as extreme values. This is good
13669 enough for windows, which can't have more than INT_MAX lines anyway.
13671 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
13673 * Require libxml/parser.h to avoid compilation warning.
13675 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
13677 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
13678 since this reportedly can destroy thread storage.
13680 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
13682 * syntax.c (find_defun_start): Update all cache variables if
13683 exiting early (Bug#9401).
13685 2011-08-30 Eli Zaretskii <eliz@gnu.org>
13687 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
13689 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
13690 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
13691 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
13693 * term.c (tty_append_glyph): New function.
13694 (produce_stretch_glyph): Static function and its prototype deleted.
13696 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
13699 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
13701 * image.c (parse_image_spec): Check for nonnegative, not for positive,
13702 when checking :margin (Bug#9390).
13703 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
13704 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
13705 so that the name doesn't mislead. All uses changed.
13707 2011-08-28 Johan Bockgård <bojohan@gnu.org>
13709 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
13712 2011-08-27 Eli Zaretskii <eliz@gnu.org>
13714 * xdisp.c (move_it_to): Don't bail out early when reaching
13715 position beyond to_charpos, if we are scanning backwards.
13716 (move_it_vertically_backward): When DY == 0, make sure we get to
13717 the first character in the line after the newline.
13719 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
13721 * ccl.c: Improve and simplify overflow checking (Bug#9196).
13722 (ccl_driver): Do not generate an out-of-range pointer.
13723 (Fccl_execute_on_string): Remove unnecessary check for
13724 integer overflow, noted by Stefan Monnier in
13725 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
13726 Remove a FIXME that didn't need fixing.
13727 Simplify the newly-introduced buffer reallocation code.
13729 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
13731 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
13733 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
13735 Integer and memory overflow issues (Bug#9196).
13737 * doc.c (get_doc_string): Rework so that
13738 get_doc_string_buffer_size is the actual buffer size, rather than
13739 being 1 less than the actual buffer size; this makes xpalloc more
13742 * image.c (x_allocate_bitmap_record, cache_image):
13743 * xselect.c (Fx_register_dnd_atom):
13744 Simplify previous changes by using xpalloc.
13746 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
13747 since either will do and ptrdiff_t is convenient with xpalloc.
13749 * charset.c (charset_table_size)
13750 (struct charset_sort_data.priority): Now ptrdiff_t.
13751 (charset_compare): Don't overflow if priorities differ greatly.
13752 (Fsort_charsets): Don't assume list length fits in int.
13753 Check for size-calculation overflow when allocating sort data.
13754 (syms_of_charset): Allocate an initial charset table that is
13755 just under 64 KiB, to avoid problems with glibc malloc and mmap.
13757 * cmds.c (internal_self_insert): Check for size-calculation overflow.
13759 * composite.h (struct composition.glyph_len): Now int, not unsigned.
13760 The actual value is always <= INT_MAX, and leaving it unsigned made
13761 overflow checking harder.
13763 * dispextern.h (struct glyph_matrix.rows_allocated)
13764 (struct face_cache.size): Now ptrdiff_t, for convenience in use
13765 with xpalloc. The values are still always <= INT_MAX.
13767 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
13769 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
13770 (SAFE_NALLOCA): New macro.
13772 * region-cache.c (struct boundary.pos, find_cache_boundary)
13773 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
13774 (set_cache_region, invalidate_region_cache)
13775 (revalidate_region_cache, know_region_cache, region_cache_forward)
13776 (region_cache_backward, pp_cache):
13777 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
13778 so that ptrdiff_t * can be passed to xpalloc.
13779 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
13780 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
13781 (pp_cache): Don't assume cache_len fits in int.
13782 * region-cache.h: Adjust extern decls to match.
13784 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
13785 EMACS_INT, since either will do, for xpalloc.
13787 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
13788 (xnmalloc, xnrealloc, xpalloc): New functions.
13790 * bidi.c (bidi_shelve_header_size): New constant.
13791 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
13792 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
13794 * bidi.c (bidi_cache_shrink):
13795 * buffer.c (overlays_at, overlays_in, record_overlay_string)
13797 Don't update size of array until after memory allocation succeeds,
13798 because xmalloc/xrealloc may not return.
13799 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
13800 now that we have proper integer overflow checking.
13801 (record_overlay_string, overlay_strings): Catch overflows when
13802 calculating size of overlay_str_buf.
13804 * callproc.c (Fcall_process): Check for size overflow when
13805 calculating size of args2.
13806 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
13807 Normally we prefer signed values, but sticking with ptrdiff_t would
13808 require adding more-complicated checks.
13810 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
13811 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
13812 Redo buffer-overflow calculations to avoid integer overflow.
13813 Add a FIXME comment where memory seems to be over-allocated.
13815 * character.c (Fstring): Check for size-calculation overflow.
13817 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
13818 unnecessary integer overflow. Check for size overflow.
13819 (encode_coding_object): Don't update size until xmalloc succeeds.
13821 * composite.c (get_composition_id): Check for overflow in glyph
13822 length calculations.
13824 Integer and memory overflow fixes for display code.
13825 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
13826 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
13827 (scrolling_window): Check for overflow in size calculations.
13828 (line_draw_cost, realloc_glyph_pool, add_row_entry):
13829 Don't assume glyph table len fits in int.
13830 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
13831 (row_table_size): Now ptrdiff_t, not int.
13832 (scrolling_window): Avoid overflow in size calculations.
13833 Don't update size until allocation succeeds.
13834 * fns.c (concat): Check for overflow in size calculations.
13835 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
13836 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
13837 (NEXT_ALMOST_PRIME_LIMIT): New constant.
13839 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
13840 (get_doc_string): Check for size calculation overflow.
13841 Don't update size until allocation succeeds.
13842 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
13843 EMACS_INT, where ptrdiff_t will do.
13844 (Fsubstitute_command_keys): Check for string overflow.
13846 * editfns.c (set_time_zone_rule): Don't assume environment length
13848 (message_length): Now ptrdiff_t, not int.
13849 (Fmessage_box): Don't update size until allocation succeeds.
13850 Don't assume message length fits in int.
13851 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
13853 * emacs.c (main): Do not reallocate argv, since there is a null at
13854 the end that can be overwritten, and this way there's no need to

13973 (Fx_change_window_property): Use ptrdiff_t, not int, to count
13974 sizes, since they can exceed INT_MAX in size. Check for size

13984 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
13985 (X_LONG_MIN): New macros.
13986 Use them to make the following changes clearer.
13987 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.

13990 (SELECTION_QUANTUM): Remove, replacing with ...
13991 (selection_quantum): ... new function, which avoids overflow.
13993 (struct selection_data.size): Now ptrdiff_t, not int, to avoid

14011 Don't store size until memory allocation succeeds.
14012 (x_get_window_property): Plug memory leak on memory exhaustion.
14013 Don't double-block input; malloc is safe here. Don't assume 2**34
14014 - 4 fits in unsigned long. Add an xassert to check
14015 XGetWindowProperty overflow. Be more careful about overflow
14016 calculations, and distinguish size from memory overflow better.
14017 (receive_incremental_selection): When tracing, don't assume
14018 unsigned int is less than INT_MAX.
14019 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory

14023 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
14024 result parameters unless successful. Rely on cons_to_unsigned
14025 to report problems with elements; the old code wasn't right anyway.
14026 (x_check_property_data): Check for int overflow; we cannot use
14027 a wider type due to X limits.

14060 * lisp.h (hash_lookup, hash_put):
14061 * minibuf.c (Ftest_completion):
14062 Use ptrdiff_t for hash table indexes, not int (which is too
14063 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
14064 32-bit --with-wide-int hosts).
14066 * charset.c (Fdefine_charset_internal): Check for integer overflow.
14067 Add a FIXME comment about memory leaks.

14096 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
14097 (x_send_scroll_bar_event): Likewise. Check that the size does not
14098 exceed limits imposed by XClientMessageEvent, as well as the usual
14099 ptrdiff_t and size_t limits.

14102 (make_lispy_movement): Use same integer type in forward decl
14103 that is used in the definition.
14104 (read_key_sequence, keyremap_step):
14105 Change bufsize argument back to int, undoing my 2011-03-30 change.
14106 We prefer signed types, and int is wide enough here.
14107 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
14108 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
14109 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
14110 length, not size_t. Use ptrdiff_t for index, not int.
14111 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
14112 possibility of integer overflow.

14140 Prefer int to unsigned where either will do.
14141 (tiff_handler): New function, combining the cores of the
14142 old tiff_error_handler and tiff_warning_handler.
14143 This function is rewritten to use vsnprintf and thereby avoid
14144 stack buffer overflows. It uses only the features of vsnprintf
14145 that are common to both POSIX and native Microsoft.
14146 (tiff_error_handler, tiff_warning_handler): Use it.
14147 (tiff_load, gif_load, imagemagick_load_image):
14148 Don't assume :index value fits in 'int'.
14149 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
14150 (imagemagick_load_image): Check that crop parameters fit into
14151 the integer types that MagickCropImage accepts. Don't assume
14152 Vimagemagick_render_type has a nonnegative value. Don't assume

14168 (handle_single_display_spec): If the display spec is of the form
14169 `(space ...)', and specifies display in the text area, return 2
14171 (try_cursor_movement): Check for the need to scroll more
14172 accurately, and prefer exact match for point under bidi.
14173 Don't advance `row' beyond the last row of the window.

14191 buffers, return left-to-right.
14192 (set_cursor_from_row): Consider candidate row a win if its glyph

14194 positioning on the newline at EOL of R2L text within L2R
14195 paragraph, and vice versa.
14196 (try_cursor_movement): Check continued rows, in addition to
14197 continuation rows. Fixes unwarranted scroll when point enters a
14198 continued line of R2L text within an L2R paragraph, or vice versa.
14199 (cursor_row_p): Consider the case of point being equal to
14200 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving

14229 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
14230 instead of CHAR_TO_BYTE. Fixes a crash when a completion
14231 candidate is selected by the mouse, and that candidate has a
14232 composed character under the mouse.
14234 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
14235 coordinates reported by pos-visible-in-window-p for a composed
14236 character in column zero.
14238 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>

14242 2011-08-22 Eli Zaretskii <eliz@gnu.org>
14244 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
14245 consider it a hit if to_charpos is anywhere in the range of the
14246 composed buffer positions.
14248 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
14250 * image.c (gif_load): Don't assume that each subimage has the same
14251 dimensions as the base image. Handle disposal method that is
14252 "undefined" by the gif spec (Bug#9335).
14254 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
14256 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

14266 a composition, take its buffer position from IT->cmp_it.charpos.
14267 Fixes cursor positioning at the beginning of a line that begins
14268 with a composed character.
14270 2011-08-18 Eli Zaretskii <eliz@gnu.org>
14272 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
14273 character bidirectional type, use STRONG_L instead. Fixes crashes
14274 in a buffer produced by `describe-categories'.
14276 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
14277 members before the level stack, so they would be saved and
14278 restored when copying iterator state. Fixes incorrect reordering
14279 around TABs covered by display properties.
14281 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>

14291 2011-08-17 Eli Zaretskii <eliz@gnu.org>
14293 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
14294 has no `load' handler, try opening the file locally. (Bug#9311)
14296 2011-08-16 Ken Brown <kbrown@cornell.edu>
14298 * gmalloc.c: Expand comment.
14300 2011-08-16 Eli Zaretskii <eliz@gnu.org>
14302 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
14303 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.
14305 2011-08-16 Ken Brown <kbrown@cornell.edu>
14307 Fix memory allocation problems in Cygwin build (Bug#9273).
14309 * unexcw.c ( __malloc_initialized): Declare external variable.
14310 (fixup_executable): Force the dumped emacs to reinitialize malloc.
14312 * gmalloc.c [CYGWIN] (bss_sbrk_heapbase, bss_sbrk_heapinfo):
14314 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the
14316 (_free_internal_nolock) [CYGWIN]: Ignore requests to free storage
14317 in the static heap.
14318 [CYGWIN] (special_realloc): New function.
14319 (_realloc_internal_nolock) [CYGWIN]: Use the new function on
14320 requests to realloc storage in the static heap.
14322 2011-08-15 Paul Eggert <eggert@cs.ucla.edu>
14324 * bidi.c (bidi_initialize): Remove unused local.
14326 2011-08-15 Eli Zaretskii <eliz@gnu.org>
14329 * biditype.h: Remove file.

14331 * deps.mk (bidi.o): Remove biditype.h and bidimirror.h.
14333 * dispextern.h: Fix a typo in the comment to bidi_type_t.
14335 * chartab.c: Improve commentary for the uniprop_table API.
14337 * bidi.c (bidi_paragraph_init): Support zero value of
14338 bidi_ignore_explicit_marks_for_paragraph_level.
14339 (bidi_initialize): Use uniprop_table instead of including
14340 biditype.h and bidimirror.h.
14342 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
14343 coordinates of the iterator when restoring from ppos_it.
14346 2011-08-14 Kenichi Handa <handa@m17n.org>
14348 * process.c (create_process): Call setup_process_coding_systems
14349 after the pid of the process is set to -1 (Bug#8162).
14351 2011-08-14 Eli Zaretskii <eliz@gnu.org>
14353 * xdisp.c (move_it_in_display_line_to): Don't invoke
14354 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
14355 ppos_it. Fixes vertical cursor motion when line beginning is
14356 covered by an image. (Bug#9296)
14358 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
14360 * nsterm.h (ns_run_ascript): Declare.
14361 (NSAPP_DATA2_RUNASSCRIPT): Define.
14363 * nsfns.m (as_script, as_result, as_status): New static variables.
14364 (ns_run_ascript): New function.
14365 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
14366 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
14367 the event loop. Get status from as_status (Bug#7276).
14369 * nsterm.m (sendEvent): If event is NSApplicationDefined and
14370 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
14371 the event loop (Bug#7276).
14373 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
14375 * gnutls.c (QCgnutls_bootprop_priority)
14376 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
14377 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
14378 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
14379 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
14380 (QCgnutls_bootprop_verify_hostname_error)
14381 (QCgnutls_bootprop_callbacks_verify): Rename from
14382 Qgnutls_bootprop_..., all uses changed.
14384 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
14387 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
14389 * xfaces.c (Qframe_set_background_mode): Now static.
14390 * dispextern.h (Qframe_set_background_mode): Remove decl.

14394 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
14396 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
14397 (Fnetwork_interface_list): Allocate in increments of bytes instead
14398 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
14399 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
14401 (struct ifflag_def): notrailers is smart on OSX.
14402 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
14403 Get hardware address with getifaddrs if available.
14405 2011-08-12 Eli Zaretskii <eliz@gnu.org>
14407 * xdisp.c (iterate_out_of_display_property): xassert that
14408 IT->position is set to within IT->object's boundaries. Break from
14409 the loop as soon as EOB is reached; avoids infloops in redisplay
14410 when IT->position is set up wrongly due to some bug.
14411 Set IT->current to match the bidi iterator unconditionally.
14412 (push_display_prop): Allow GET_FROM_STRING as IT->method on
14413 entry. Force push_it to save on the stack the current
14414 buffer/string position, to be restored by pop_it. Fix flags in
14415 the iterator structure wrt the object coming from a display
14416 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
14417 properties. (Bug#9284)
14419 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
14421 * fontset.c (fontset_get_font_group): Add proper type checks.
14424 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14426 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
14427 and LC_VERSION_MIN_MACOSX.
14428 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
14429 (dump_it) [LC_FUNCTION_STARTS]: Use it.
14431 2011-08-08 Eli Zaretskii <eliz@gnu.org>
14433 * xdisp.c (forward_to_next_line_start): Allow to use the
14434 no-display-properties-and-no-overlays under bidi display.
14435 Set disp_pos in the bidi iterator to avoid searches for display
14436 properties and overlays.
14438 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
14440 * editfns.c (Fset_time_zone_rule): Document relationship with the
14443 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
14444 the font entity extracted from the cache (Bug#8109).
14446 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
14448 * composite.c (autocmp_chars): Don't reset point. That is done by
14449 restore_point_unwind (Bug#5984).
14451 2011-08-07 Juri Linkov <juri@jurta.org>
14453 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
14454 to show the arg `TIME' instead of `TIMEVAL'.
14456 2011-08-06 Eli Zaretskii <eliz@gnu.org>
14458 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
14459 display property strides EOL and includes a newline, as in
14460 longlines-mode. (Bug#9254)
14461 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
14462 word-wrap under bidirectional display. (Bug#9224)
14464 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
14465 is non-zero, even if the data buffer is NULL. Fixes a crash in
14466 vertical-motion with longlines-mode. (Bug#9254)
14468 2011-08-05 Eli Zaretskii <eliz@gnu.org>
14470 * bidi.c <bidi_cache_total_alloc>: Now static.
14471 (bidi_initialize): Initialize bidi_cache_total_alloc.
14473 * xdisp.c (display_line): Release buffer allocated for shelved bidi
14476 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
14477 amount allocated this far in `bidi_cache_total_alloc'.
14478 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
14479 non-zero, only free the data buffer without restoring the cache
14480 contents. All callers changed.
14482 * dispextern.h (bidi_unshelve_cache): Update prototype.
14484 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
14485 (move_it_in_display_line, move_it_to)
14486 (move_it_vertically_backward, move_it_by_lines): Replace the call
14487 to xfree to an equivalent call to bidi_unshelve_cache.
14488 (move_it_in_display_line_to): Fix logic of returning
14489 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
14491 2011-08-05 Eli Zaretskii <eliz@gnu.org>
14493 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
14494 came from a string character with a `cursor' property. (Bug#9229)
14496 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
14498 * Makefile.in (LIB_PTHREAD): New variable.
14499 (LIBES): Add LIB_PTHREAD (Bug#9216).
14501 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
14502 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
14504 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
14506 * regex.c (re_iswctype): Remove some redundant boolean conversions.
14508 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
14510 * xterm.c (x_find_topmost_parent): New function.
14511 (x_set_frame_alpha): Find topmost parent window with
14512 x_find_topmost_parent and set the property there also (bug#9181).
14513 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
14515 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
14517 * callproc.c (Fcall_process): Avoid vfork clobbering
14518 the local vars buffer, coding_systems, current_dir.
14520 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
14522 * keymap.c (Fmake_composed_keymap): Move to subr.el.
14524 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
14526 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
14527 so that it is not optimized away.
14529 * xdisp.c (compute_display_string_pos): Remove unused local.
14531 2011-08-02 Eli Zaretskii <eliz@gnu.org>
14533 Fix slow cursor motion and scrolling in large buffers with
14534 selective display, like Org Mode buffers. (Bug#9218)
14536 * dispextern.h (struct bidi_it): New member disp_prop_p.
14538 * xdisp.c: Remove one-slot cache of display string positions.
14539 (compute_display_string_pos): Accept an additional argument
14540 DISP_PROP_P; callers changed. Scan at most 5K characters forward
14541 for a display string or property. If found, set DISP_PROP_P
14544 * bidi.c (bidi_fetch_char): Accept an additional argument
14545 DISP_PROP_P, and pass it to compute_display_string_pos.
14546 Only handle text covered by a display string if DISP_PROP_P is returned
14547 non-zero. All callers of bidi_fetch_char changed.
14549 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
14551 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
14553 2010-12-03 Don March <don@ohspite.net>
14555 * keymap.c (Fdefine_key): Fix non-prefix key error message when
14556 last character M-[char] is translated to ESC [char] (bug#7541).
14558 2011-08-02 Kenichi Handa <handa@m17n.org>
14560 * lisp.h (uniprop_table): Extern it.
14562 * chartab.c (uniprop_table): Make it non-static.
14564 2011-08-01 Eli Zaretskii <eliz@gnu.org>
14566 * xdisp.c (forward_to_next_line_start): Accept additional argument
14567 BIDI_IT_PREV, and store into it the state of the bidi iterator had
14569 (reseat_at_next_visible_line_start): Use the bidi iterator state
14570 returned by forward_to_next_line_start to restore the state of
14571 it->bidi_it after backing up to previous newline. (Bug#9212)
14573 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
14575 * regex.c (re_comp): Protoize.
14576 (re_exec): Fix return type.
14577 (regexec): Fix type of `ret'. (Bug#9203)
14579 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14581 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
14582 This is needed if max-image-size is a floating-point number.
14584 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
14586 * print.c (print_object): Print empty symbol as ##.
14588 * lread.c (read1): Read ## as empty symbol.
14590 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
14592 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
14593 setting frame foreground color (Bug#9175).
14594 (x_set_background_color): Likewise.
14596 * nsmenu.m (-setText): Size tooltip dimensions precisely to
14597 contents (Bug#9176).
14598 (EmacsTooltip -init): Remove bezels and add shadows to
14601 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
14602 or scroll bar (Bug#8470).
14604 * nsfont.m (nsfont_open): Remove assignment to voffset and
14605 unnecessary vars hshink, expand, hd, full_height, min_height.
14606 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
14608 * nsterm.h (nsfont_info): Remove voffset field.
14610 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
14612 Implement strike-through and overline on NextStep (Bug#8863).
14614 * nsfont.m (nsfont_open): Use underline position provided by font,
14615 instead of hard-coded value of 2.
14616 (nsfont_draw): Call ns_draw_text_decoration instead.
14618 * nsterm.h: Add declaration for ns_draw_text_decoration.
14620 * nsterm.m (ns_draw_text_decoration): New function for drawing
14621 underline, overline, and strike-through.
14622 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
14623 ns_draw_text_decoration. Change treatment of cursor drawing to
14624 accommodate underlining, etc.
14626 2011-07-28 Eli Zaretskii <eliz@gnu.org>
14628 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
14631 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14633 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
14634 Without this fix, if a signal arrives just after memory fills up,
14635 'malloc' might be invoked reentrantly.
14637 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
14638 In other words, assume that every image size is allowed, on non-X
14639 hosts. This assumption is probably wrong, but it lets Emacs compile.
14641 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
14643 * regex.c (re_iswctype): Convert return values to boolean.
14645 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
14647 * xdisp.c (compute_display_string_pos): Don't use cached display
14648 string position if the buffer had its restriction changed.
14651 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14653 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
14655 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14657 Integer signedness and overflow and related fixes. (Bug#9079)
14659 * bidi.c: Integer size and overflow fixes.
14660 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
14661 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
14662 (bidi_cache_find_level_change, bidi_cache_ensure_space)
14663 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
14664 (bidi_find_other_level_edge):
14665 Use ptrdiff_t instead of EMACS_INT where either will do.
14666 This works better on 32-bit hosts configured --with-wide-int.
14667 (bidi_cache_ensure_space): Check for size-calculation overflow.
14668 Use % rather than repeated addition, for better worst-case speed.
14669 Don't set bidi_cache_size until after xrealloc returns, because it
14671 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
14672 (bidi_cache_ensure_space): Also check that the bidi cache size
14673 does not exceed that of the largest Lisp string or buffer. See Eli
14674 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
14676 * alloc.c (__malloc_size_t): Remove.
14677 All uses replaced by size_t. See Andreas Schwab's note
14678 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
14680 * image.c: Improve checking for integer overflow.
14681 (check_image_size): Assume that f is nonnull, since
14682 it is always nonnull in practice. This is one less thing to
14683 worry about when checking for integer overflow later.
14684 (x_check_image_size): New function, which checks for integer
14685 overflow issues inside X.
14686 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
14687 This removes the need for a memory_full check.
14688 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
14689 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
14690 (xbm_read_bitmap_data): Change locals back to 'int', since
14691 their values must fit in 'int'.
14692 (xpm_load_image, png_load, tiff_load):
14693 Invoke x_create_x_image_and_pixmap earlier,
14694 to avoid much needless work if the image is too large.
14695 (tiff_load): Treat overly large images as if
14696 x_create_x_image_and_pixmap failed, not as malloc failures.
14697 (gs_load): Use x_check_image_size.
14699 * gtkutil.c: Omit integer casts.
14700 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
14701 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
14703 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
14705 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
14706 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
14707 would wrongly return t on a 64-bit host.
14709 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
14710 The plain *_OVERFLOW macros run afoul of GCC bug 49705
14711 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
14712 and therefore cause GCC to emit a bogus diagnostic in some cases.
14714 * image.c: Integer signedness and overflow and related fixes.
14715 This is not an exhaustive set of fixes, but it's time to
14716 record what I've got.
14717 (lookup_pixel_color, check_image_size): Remove redundant decls.
14718 (check_image_size): Don't assume that arbitrary EMACS_INT values
14719 fit in 'int', or that arbitrary 'double' values fit in 'int'.
14720 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
14721 (tiff_load, imagemagick_load_image):
14722 Check for overflow in size calculations.
14723 (x_create_x_image_and_pixmap): Remove unnecessary test for
14724 xmalloc returning NULL; that can't happen.
14725 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
14726 (xpm_color_bucket): Use better integer hashing function.
14727 (xpm_cache_color): Don't possibly over-allocate memory.
14728 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
14729 (gif_memory_source):
14730 Use ptrdiff_t, not int or size_t, to record sizes.
14731 (png_load): Don't assume values greater than 2**31 fit in 'int'.
14732 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
14733 either works, as we prefer signed integers.
14734 (tiff_read_from_memory, tiff_write_from_memory):
14735 Return tsize_t, not size_t, since that's what the TIFF API wants.
14736 (tiff_read_from_memory): Don't fail simply because the read would
14737 go past EOF; instead, return a short read.
14738 (tiff_load): Omit no-longer-needed casts.
14739 (Fimagemagick_types): Don't assume size fits into 'int'.
14741 Improve hashing quality when configured --with-wide-int.
14742 * fns.c (hash_string): New function, taken from sxhash_string.
14743 Do not discard information about ASCII character case; this
14744 discarding is no longer needed.
14745 (sxhash-string): Use it. Change sig to match it. Caller changed.
14746 * lisp.h: Declare it.
14747 * lread.c (hash_string): Remove, since we now use fns.c's version.
14748 The fns.c version returns a wider integer if --with-wide-int is
14749 specified, so this should help the quality of the hashing a bit.
14751 * emacs.c: Integer overflow minor fix.
14752 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
14753 Define only if GNU_LINUX.
14754 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
14756 * dispnew.c: Integer signedness and overflow fixes.
14757 Remove unnecessary forward decls, that were a maintenance hassle.
14758 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
14760 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
14761 (scrolling_window): Use ptrdiff_t, not int, for byte count.
14762 (prepare_desired_row, line_draw_cost):
14763 Use int, not unsigned, where either works.
14764 (save_current_matrix, restore_current_matrix):
14765 Use ptrdiff_t, not size_t, where either works.
14766 (init_display): Check for overflow more accurately, and without
14767 relying on undefined behavior.
14769 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
14770 Remove, replacing with the new symbols in lisp.h. All uses changed.
14771 * fileio.c (make_temp_name):
14772 * filelock.c (lock_file_1, lock_file):
14773 * xdisp.c (message_dolog):
14774 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
14775 Use pMd etc. instead.
14776 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
14777 replacing the pWIDE etc. symbols removed from editfns.c.
14779 * keyboard.h (num_input_events): Now uintmax_t.
14780 This is (very slightly) less likely to mess up due to wraparound.
14783 * buffer.c: Integer signedness fixes.
14784 (alloc_buffer_text, enlarge_buffer_text):
14785 Use ptrdiff_t rather than size_t when either will do, as we prefer
14788 * alloc.c: Integer signedness and overflow fixes.
14789 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
14790 (__malloc_size_t): Default to size_t, not to int.
14791 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
14792 (Fgarbage_collect, mark_object_loop_halt, mark_object):
14793 Prefer ptrdiff_t to size_t when either would do, as we prefer
14795 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
14796 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
14797 Now const. Initialize with values that are in range even if char
14799 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
14800 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
14801 These functions do the right thing with sizes > 2**32.
14802 (check_depth): Now ptrdiff_t, not int.
14803 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
14804 Adjust to new way of storing sizes. Check for size overflow bugs
14806 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
14807 slightly wrong anyway, as it missed one instance of
14808 XMALLOC_OVERRUN_CHECK_OVERHEAD.
14809 (refill_memory_reserve): Omit needless cast to size_t.
14810 (mark_object_loop_halt): Mark as externally visible.
14812 * xselect.c: Integer signedness and overflow fixes.
14813 (Fx_register_dnd_atom, x_handle_dnd_message):
14814 Use ptrdiff_t, not size_t, since we prefer signed.
14815 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
14816 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
14817 x_dnd_atoms_size and x_dnd_atoms_length.
14819 * doprnt.c: Prefer signed to unsigned when either works.
14821 * doprnt.c (doprnt):
14823 * xdisp.c (vmessage):
14824 Use ptrdiff_t, not size_t, when using or implementing doprnt,
14825 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
14826 prefer signed arithmetic to avoid comparison confusion.
14827 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
14828 but is a bit tricky.
14830 Assume freestanding C89 headers, string.h, stdlib.h.
14831 * data.c, doprnt.c, floatfns.c, print.c:
14832 Include float.h unconditionally.
14833 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
14834 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
14835 * regex.c: Likewise for stddef.h, string.h.
14836 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
14837 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
14838 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
14839 (STDC_HEADERS): Remove obsolete defines.
14840 * sysdep.c: Include limits.h unconditionally.
14842 Assume support for memcmp, memcpy, memmove, memset.
14843 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
14844 * regex.c (memcmp, memcpy):
14845 Remove; we assume C89 now.
14847 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
14848 (__malloc_safe_bcopy): Remove; no longer needed.
14850 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
14851 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
14852 well either way, and we prefer signed to unsigned.
14854 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
14856 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
14857 closes the connection while we're reading (bug#9182).
14859 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
14861 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
14862 are specified (Bug#9168).
14864 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
14866 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
14867 Found by GCC static checking and --with-wide-int on a 32-bit host.
14869 2011-07-25 Eli Zaretskii <eliz@gnu.org>
14871 * xdisp.c (compute_display_string_pos): Fix logic of caching
14872 previous display string position. Initialize cached_prev_pos to
14873 -1. Fixes slow-down at the beginning of a buffer.
14875 2011-07-24 Eli Zaretskii <eliz@gnu.org>
14877 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
14878 for attrs[LFACE_FONTSET_INDEX].
14880 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
14882 * xml.c (parse_region): Remove unused local
14883 that was recently introduced.
14885 2011-07-23 Eli Zaretskii <eliz@gnu.org>
14887 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
14888 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
14890 * xdisp.c (move_it_in_display_line_to): Record the best matching
14891 position for TO_CHARPOS while scanning the line, and restore it on
14892 exit if none of the characters scanned was an exact match.
14893 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
14894 when exact match is impossible due to invisible text, and the
14895 lines are truncated.
14897 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
14899 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
14902 2011-07-22 Eli Zaretskii <eliz@gnu.org>
14904 Fix a significant slow-down of cursor motion with C-n, C-p,
14905 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
14906 auto-repeat under bidi redisplay in fontified buffers.
14907 * xdisp.c (compute_stop_pos_backwards): New function.
14908 (next_element_from_buffer): Call compute_stop_pos_backwards to
14909 find a suitable prev_stop when we find ourselves before
14911 (reseat): Don't look for prev_stop, as that could mean a very long
14913 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
14914 <cached_disp_overlay_modiff>: Cache for last found display string
14916 (compute_display_string_pos): Return the cached position if asked
14917 about the same buffer in the same area of character positions, and
14918 the buffer wasn't changed since the time the display string
14919 position was cached.
14921 2011-07-22 Eli Zaretskii <eliz@gnu.org>
14923 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
14924 is an integer, which is important for empty lines. (Bug#9149)
14926 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
14928 * frame.c (Fmodify_frame_parameters): In tty case, update the
14929 default face if necessary (Bug#4238).
14931 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
14933 * editfns.c (Fstring_to_char): No need to explain what a character
14934 is in the docstring (Bug#6576).
14936 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
14938 * xml.c (parse_region): Make sure we always return a tree.
14940 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
14942 * xml.c (parse_region): If a document contains only comments,
14945 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
14947 * xml.c (make_dom): Return comments, too.
14949 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
14952 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
14953 and the surrounding thread.
14954 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
14955 rather than fgets, and retry after EINTR. Otherwise, 'emacs
14956 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
14958 * s/openbsd.h (BROKEN_SIGIO): Define.
14959 * unexelf.c (unexec) [__OpenBSD__]:
14960 Don't update the .mdebug section of the Alpha COFF symbol table.
14962 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
14964 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
14967 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
14969 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
14970 This fixes some race conditions on the permissions of any newly
14973 * alloc.c (valid_pointer_p): Use pipe, not open.
14974 This fixes some permissions issues when debugging.
14976 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
14977 If fchown fails to set both uid and gid, try to set just gid,
14978 as that is sometimes allowed. Adjust the file's mode to eliminate
14979 setuid or setgid bits that are inappropriate if fchown fails.
14981 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
14983 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
14984 to compare Lisp_Objects.
14985 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
14986 global_gnutls_log_level, don't mistake it for a Lisp_Object.
14987 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
14989 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
14991 * lread.c (read_integer): Unread even EOF character.
14992 (read1): Likewise. Properly record start position of symbol.
14994 * lread.c (read1): Read `#:' as empty uninterned symbol if no
14995 symbol character follows.
14997 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
14999 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
15000 This works around a problem with the previous change to Fcopy_file.
15001 Recent glibc declares fchown with __attribute__((warn_unused_result)),
15002 and without this change, GCC might complain about discarding
15003 fchown's return value.
15005 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
15007 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
15009 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
15011 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
15013 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
15015 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
15016 it's used from the C level.
15018 * process.c: Use the same condition for POLL_FOR_INPUT in both
15019 keyboard.c and process.c (bug#1858).
15021 2011-07-09 Lawrence Mitchell <wence@gmx.li>
15023 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
15024 (Fgnutls_boot): Use it.
15026 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
15028 * doc.c (Fsubstitute_command_keys): Revert last change.
15030 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
15032 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
15033 quotes the next character, and doesn't affect other longer
15034 sequences (bug#8935).
15036 * lread.c (syms_of_lread): Clarify that is isn't only
15037 `eval-buffer' and `eval-defun' that's affected by
15038 `lexical-binding' (bug#8460).
15040 2011-07-15 Eli Zaretskii <eliz@gnu.org>
15042 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
15043 bidi redisplay when a line includes both an image and is truncated.
15045 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
15047 Fix minor problems found by static checking.
15048 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
15049 (elsz): Now a signed constant, not a size_t var. We prefer signed
15050 types to unsigned, to avoid integer comparison confusion. Without
15051 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
15052 "cannot optimize loop, the loop counter may overflow", a symptom
15054 * indent.c (Fvertical_motion): Mark locals as initialized.
15055 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
15057 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
15059 * search.c (Fre_search_backward): Mention `case-fold-search' in
15060 all the re_search_* functions (bug#8138).
15062 * keyboard.c (Fopen_dribble_file): Document when the file is
15065 2011-07-14 Eli Zaretskii <eliz@gnu.org>
15067 * bidi.c (bidi_dump_cached_states): Fix format of displaying
15070 Support bidi reordering of display and overlay strings.

15073 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
15074 (reseat_to_string): Initialize bidi_it->string.s and
15075 bidi_it->string.schars.
15076 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
15077 NULL (avoids a crash in bidi_paragraph_init).
15078 Initialize itb.string.lstring.
15079 (init_iterator): Call bidi_init_it only of a valid
15080 buffer position was specified. Initialize paragraph_embedding to
15082 (reseat_to_string): Initialize the bidi iterator.
15083 (display_string): If we need to ignore text properties of
15084 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
15085 original value of -1 will not work with bidi.)
15086 (compute_display_string_pos): First arg is now struct
15087 `text_pos *'; all callers changed. Support display properties on
15089 (compute_display_string_end): Support display properties on Lisp
15091 (init_iterator, reseat_1, reseat_to_string): Initialize the
15092 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
15093 when iterating on a string not from display properties).
15094 (compute_display_string_pos, compute_display_string_end):
15095 Fix calculation of the object to scan. Fixes an error when using
15097 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
15098 base_level_stop; instead, set base_level_stop to BEGV.
15099 Fixes crashes in vertical-motion.
15100 (next_element_from_buffer): Improve commentary for when
15101 the iterator is before prev_stop.
15102 (init_iterator): Initialize bidi_p from the default value of
15103 bidi-display-reordering, not from buffer-local value. Use the
15104 buffer-local value only if initializing for buffer iteration.
15105 (handle_invisible_prop): Support invisible properties on strings
15106 that are being bidi-reordered.
15107 (set_iterator_to_next): Support bidi reordering of C strings and
15109 (next_element_from_string): Support bidi reordering of Lisp
15111 (handle_stop_backwards): Support Lisp strings as well.
15112 (display_string): Support display of R2L glyph rows.
15113 Use IT_STRING_CHARPOS when displaying from a Lisp string.
15114 (init_iterator): Don't initialize it->bidi_p for strings
15116 (reseat_to_string): Initialize it->bidi_p for strings here.
15117 (next_element_from_string, next_element_from_c_string)
15118 (next_element_from_buffer): Add xassert's for correspondence
15119 between IT's object being iterated and it->bidi_it.string
15121 (face_before_or_after_it_pos): Support bidi iteration.
15122 (next_element_from_c_string): Handle the case of the first string
15123 character that is not the first one in the visual order.
15124 (get_visually_first_element): New function, refactored from common
15125 parts of next_element_from_buffer, next_element_from_string, and
15126 next_element_from_c_string.
15127 (tool_bar_lines_needed, redisplay_tool_bar)
15128 (display_menu_bar): Force left-to-right direction. Add a FIXME
15129 comment for making that be controlled by a user option.
15130 (push_it, pop_it): Save and restore the state of the
15131 bidi iterator. Save and restore the bidi_p flag.
15132 (pop_it): Iterate out of display property for string iteration as
15134 (iterate_out_of_display_property): Support iteration over strings.
15135 (handle_single_display_spec): Set up it->bidi_it for iteration
15136 over a display string, and call bidi_init_it.
15137 (handle_single_display_spec, next_overlay_string)
15138 (get_overlay_strings_1, push_display_prop): Set up the bidi
15139 iterator for displaying display or overlay strings.
15140 (forward_to_next_line_start): Don't use the shortcut if
15142 (back_to_previous_visible_line_start): If handle_display_prop
15143 pushed the iterator stack, restore the internal state of the bidi
15144 iterator by calling bidi_pop_it same number of times.
15145 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
15146 and we are bidi-iterating, don't decrement the iterator position;
15147 instead, set the first_elt flag in the bidi iterator, to produce
15149 (reseat_1): Remove redundant setting of string_from_display_prop_p.
15150 (push_display_prop): xassert that we are iterating a buffer.
15151 (push_it, pop_it): Save and restore paragraph_embedding member.
15152 (handle_single_display_spec, next_overlay_string)
15153 (get_overlay_strings_1, reseat_1, reseat_to_string)
15154 (push_display_prop): Set up the `unibyte' member of bidi_it.string
15155 correctly. Don't assume unibyte strings are not bidi-reordered.
15156 (compute_display_string_pos)
15157 (compute_display_string_end): Fix handling the case of C string.
15158 (push_it, pop_it): Save and restore from_disp_prop_p.
15159 (handle_single_display_spec, push_display_prop): Set the
15160 from_disp_prop_p flag.
15161 (get_overlay_strings_1): Reset the from_disp_prop_p flag.
15162 (pop_it): Call iterate_out_of_display_property only if we are
15163 popping after iteration over a string that came from a display
15164 property. Fix a typo in popping stretch info. Add an assertion
15165 for verifying that the iterator position is in sync with the bidi
15167 (handle_single_display_spec, get_overlay_strings_1)
15168 (push_display_prop): Fix initialization of paragraph direction for
15169 string when that of the parent object is not yet determined.
15170 (reseat_1): Call bidi_init_it to resync the bidi
15171 iterator with IT's position. (Bug#7616)
15172 (find_row_edges): If ROW->start.pos gives position
15173 smaller than min_pos, use it as ROW->minpos. (Bug#7616)
15174 (handle_stop, back_to_previous_visible_line_start, reseat_1):
15175 Reset the from_disp_prop_p flag.
15176 (SAVE_IT, RESTORE_IT): New macros.
15177 (pos_visible_p, face_before_or_after_it_pos)
15178 (back_to_previous_visible_line_start)
15179 (move_it_in_display_line_to, move_it_in_display_line)
15180 (move_it_to, move_it_vertically_backward, move_it_by_lines)
15181 (try_scrolling, redisplay_window, display_line): Use them when
15182 saving a temporary copy of the iterator and restoring it back.
15183 (back_to_previous_visible_line_start, reseat_1)

15622 subseconds part to the entropy, as that's a bit more random.
15623 Prefer signed to unsigned, since the signedness doesn't matter and
15624 in general we prefer signed. When given a limit, use a
15625 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
15626 latter isn't right if USE_2_TAGS_FOR_INTS.
15627 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
15628 not 0..VALMASK. Don't discard "excess" bits that random () returns.
15630 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
15632 * textprop.c (text_property_stickiness):
15633 Obey Vtext_property_default_nonsticky.
15634 (syms_of_textprop): Add `display' to Vtext_property_default_nonsticky.

15640 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
15641 This is more efficient than Ffile_directory_p and avoids a minor race.
15643 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
15645 * buffer.c (Foverlay_put): Say what the return value is
15648 * fileio.c (barf_or_query_if_file_exists): Check first if the file
15649 is a directory before asking whether to use the file name
15651 (barf_or_query_if_file_exists): Make the "File is a directory"
15652 error be more correct.
15654 * fns.c (Frequire): Remove the mention of the .gz files, since
15655 that's installation-specific, but keep the mention of
15656 `get-load-suffixes'.
15658 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
15660 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.
15661 Report string overflow if the output is too long.
15663 2011-07-04 Juanma Barranquero <lekktu@gmail.com>
15665 * gnutls.c (Fgnutls_boot): Don't mention :verify-error.
15666 (syms_of_gnutls): Remove duplicate DEFSYM for
15667 Qgnutls_bootprop_verify_hostname_error, an error for
15668 Qgnutls_bootprop_verify_error (which is no longer used).
15670 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
15671 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
15672 Also (re)move comments that are misplaced or no longer relevant.
15674 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
15676 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

15680 * xfaces.c (Finternal_merge_in_global_face): Modify the foreground
15681 and background color parameters if they have been changed.

15694 2011-07-02 Chong Yidong <cyd@stupidchicken.com>
15696 * keyboard.c (command_loop_1): If a down-mouse event is unbound,
15697 leave any prefix arg for the up event (Bug#1586).

15701 * lread.c (syms_of_lread): Mention single symbols defined by
15702 `defvar' or `defconst' (bug#7154).
15704 * fns.c (Frequire): Mention .el.gz files (bug#7314).
15705 (Frequire): Mention get-load-suffixes.
15707 2011-07-02 Martin Rudalics <rudalics@gmx.at>
15709 * window.h (window): Remove clone_number slot.

15773 * eval.c (struct backtrace): Simplify and port the data structure.
15774 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
15775 signed bit field, as this assumption is not portable and it makes
15776 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
15777 "char debug_on_exit : 1" as this is not portable either; instead,
15778 use the portable "unsigned int debug_on_exit : 1". Remove unused
15779 member evalargs. Remove obsolete comments about cc bombing out.
15781 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>
15783 * xsettings.c: Include glib-object.h, gio/gio.h if HAVE_GSETTINGS.

15851 (emacs_fixed_get_preferred_height): Use min_width/height from
15852 frames size_hint to set minimum and natural (Bug#8919).
15853 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
15854 and use min_width/height from frames size_hint to set
15855 min_width/height (Bug#8919).

15948 (PRINTPREPARE, printchar, strout):
15949 Don't set size unless allocation succeeds.
15951 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
15952 for sizes. Check for string overflow more accurately.

15967 to improve quality of diagnostics for out-of-range radices.
15968 Calculate buffer size correctly for out-of-range radices.
15969 (read1): Check for integer overflow in radices, and in
15970 read-circle numbers.
15971 (read_escape): Avoid int overflow.
15972 (Fload, openp, read_buffer_size, read1)
15973 (substitute_object_recurse, read_vector, read_list, map_obarray):

15996 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
15997 The following patches are for when GLYPH_DEBUG && !XASSERT.
15998 * dispextern.h (trace_redisplay_p, dump_glyph_string):
15999 * dispnew.c (flush_stdout):
16000 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
16001 Mark as externally visible.
16002 * dispnew.c (check_window_matrix_pointers): Now static.
16003 * dispnew.c (window_to_frame_vpos):
16004 * xfns.c (unwind_create_frame):

16011 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
16013 (debug_method_add): Use va_list and vsprintf rather than relying
16014 on undefined behavior with wrong number of arguments.
16015 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
16016 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
16017 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
16018 since we're not interested in debugging glyphs with old libraries.
16019 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
16020 GCC 4.6.0's static checking.
16022 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>

16055 (mouse_face_overlay_overlaps, Foverlays_in):
16056 Use ptrdiff_t, not int, for sizes.
16057 (overlays_at, overlays_in): Check for size-calculation overflow.
16059 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
16061 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
16062 (x_session_initialize): Do not assume string length fits in int.
16064 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
16065 This is unlikely, but can occur if DPI is outlandish.
16067 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
16068 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
16070 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
16071 * xrdb.c (magic_file_p, search_magic_path):
16072 Omit last arg SUFFIX; it was always 0. All callers changed.
16073 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
16075 * xfont.c (xfont_match): Avoid need for strlen.
16077 * xfns.c: Don't assume strlen fits in int.
16078 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
16080 * xdisp.c (message_log_check_duplicate): Return intmax_t,
16081 not unsigned long, as we prefer signed integers. All callers changed.
16082 Detect integer overflow in repeat count.
16083 (message_dolog): Don't assume print length fits in 39 bytes.
16084 (display_mode_element): Don't assume strlen fits in int.
16086 * termcap.c: Don't assume sizes fit in int and never overflow.
16087 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
16088 (gobble_line): Check for size-calculation overflow.
16090 * minibuf.c (Fread_buffer):
16091 * lread.c (intern, intern_c_string):
16092 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
16093 Don't assume string length fits in int.
16095 * keyboard.c (parse_tool_bar_item):
16096 * gtkutil.c (style_changed_cb): Avoid need for strlen.
16098 * font.c: Don't assume string length fits in int.
16099 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
16100 Use ptrdiff_t, not int.
16101 (font_intern_prop): Don't assume string length fits in int.
16102 Don't assume integer property fits in fixnum.
16103 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
16105 * filelock.c: Fix some buffer overrun and integer overflow issues.
16106 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
16107 Reformulate so as not to need the command string.
16108 Invoke gzip -cd rather than gunzip, as it's more portable.
16109 (lock_info_type, lock_file_1, lock_file):
16110 Don't assume pid_t and time_t fit in unsigned long.
16111 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
16112 (current_lock_owner): Prefer signed type for sizes.
16113 Use memcpy, not strncpy, where memcpy is what is really wanted.
16114 Don't assume (via atoi) that time_t and pid_t fit in int.
16115 Check for time_t and/or pid_t out of range, e.g., via a network share.
16116 Don't alloca where an auto var works fine.
16118 * fileio.c: Fix some integer overflow issues.
16119 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
16120 Don't assume string length fits in int.
16121 (directory_file_name): Don't assume string length fits in long.
16122 (make_temp_name): Don't assume pid fits in int, or that its print
16123 length is less than 20.
16125 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
16127 * coding.c (make_subsidiaries): Don't assume string length fits in int.
16129 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
16131 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
16132 We prefer signed integers, even for size calculations.
16134 * emacs.c: Don't assume string length fits in 'int'.
16135 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
16136 (main): Don't invoke strlen when not needed.
16138 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
16139 (XD_DEBUG_MESSAGE): Don't waste a byte.
16141 * callproc.c (getenv_internal_1, getenv_internal)
16142 (Fgetenv_internal):
16143 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
16145 * lread.c (invalid_syntax): Omit length argument.
16146 All uses changed. This doesn't fix a bug, but it simplifies the
16147 code away from its former Hollerith-constant appearance, and it's
16148 one less 'int' to worry about when looking at integer-overflow issues.
16149 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
16151 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
16152 This didn't break anything, but it didn't help either.
16153 It's confusing to put a bogus integer in a place where the actual
16154 value does not matter.
16155 (LIST_END_P): Remove unused macro and its bogus comment.
16156 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
16158 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
16159 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
16161 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
16162 We prefer signed types, and the value cannot exceed the EMACS_INT
16163 range anyway (because otherwise the length would not be representable).
16164 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
16165 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
16166 This avoids a GCC warning when WIDE_EMACS_INT.
16168 * indent.c (sane_tab_width): New function.
16169 (current_column, scan_for_column, Findent_to, position_indentation)
16170 (compute_motion): Use it. This is just for clarity.
16171 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
16173 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
16175 * lisp.h (lint_assume): New macro.
16176 * composite.c (composition_gstring_put_cache):
16177 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
16179 * editfns.c, insdel.c:
16180 Omit unnecessary forward decls, to simplify future changes.
16182 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
16184 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
16186 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
16187 Use much-faster test for byte-length change.
16188 Don't assume string byte-length fits in 'int'.
16189 Check that character arg fits in 'int'.
16190 (mapcar1): Declare byte as byte, for clarity.
16192 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
16194 * fns.c (concat): Catch string overflow earlier.
16195 Do not rely on integer wraparound.
16197 * dispextern.h (struct it.overlay_strings_charpos)
16198 (struct it.selective): Now EMACS_INT, not int.
16199 * xdisp.c (forward_to_next_line_start)
16200 (back_to_previous_visible_line_start)
16201 (reseat_at_next_visible_line_start, next_element_from_buffer):
16202 Don't arbitrarily truncate the value of 'selective' to int.
16204 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
16206 * composite.c: Don't truncate sizes to 'int'.
16207 (composition_gstring_p, composition_reseat_it)
16208 (composition_adjust_point): Use EMACS_INT, not int.
16209 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
16210 not EMACS_UINT, for indexes.
16212 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
16214 * buffer.c: Include <verify.h>.
16215 (struct sortvec.priority, struct sortstr.priority):
16216 Now EMACS_INT, not int.
16217 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
16218 (struct sortstr.size, record_overlay_string)
16219 (struct sortstrlist.size, struct sortlist.used):
16220 Don't truncate size to int.
16221 (record_overlay_string): Check for size-calculation overflow.
16222 (init_buffer_once): Check at compile-time, not run-time.
16224 2011-06-22 Jim Meyering <meyering@redhat.com>
16226 Don't leak an XBM-image-sized buffer
16227 * image.c (xbm_load): Free the image buffer after using it.
16229 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
16232 * composite.c (find_automatic_composition): Omit needless 'return 0;'
16233 that Sun C diagnosed.
16234 * fns.c (secure_hash): Fix pointer signedness issue.
16235 * intervals.c (static_offset_intervals): New function.
16236 (offset_intervals): Use it.
16238 2011-06-21 Leo Liu <sdl.web@gmail.com>
16241 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
16244 * fns.c (secure_hash): Rename from crypto_hash_function and change
16245 the first arg to accept symbols.
16246 (Fsecure_hash): New primitive.
16247 (syms_of_fns): New symbols.
16249 2011-06-20 Deniz Dogan <deniz@dogan.se>
16251 * process.c (Fset_process_buffer): Clarify return value in
16254 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
16256 * dispnew.c (add_window_display_history): Use BVAR.
16258 * xdisp.c (debug_method_add): Use BVAR.
16259 (check_window_end, dump_glyph_matrix, dump_glyph)
16260 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
16262 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
16265 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
16266 check till after the cache is created in init_frame_faces.
16268 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
16270 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
16272 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
16274 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
16275 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
16276 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
16278 Improve buffer-overflow checking (Bug#8873).
16279 * fileio.c (Finsert_file_contents):
16280 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
16281 Remove the old (too-loose) buffer overflow checks.
16282 They weren't needed, since make_gap checks for buffer overflow.
16283 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
16284 The old code merely checked for Emacs fixnum overflow, and relied
16285 on undefined (wraparound) behavior. The new code avoids undefined
16286 behavior, and also checks for ptrdiff_t and/or size_t overflow.
16288 * editfns.c (Finsert_char): Don't dump core with very negative counts.
16289 Tune. Don't use wider integers than needed. Don't use alloca.
16290 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
16292 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
16294 * insdel.c, lisp.h (buffer_overflow): New function.
16295 (insert_from_buffer_1, replace_range, replace_range_2):
16296 * insdel.c (make_gap_larger):
16297 * editfns.c (Finsert_char):
16298 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
16300 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
16302 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
16304 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
16306 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
16307 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
16309 * fileio.c: Don't assume EMACS_INT fits in off_t.
16310 (emacs_lseek): New static function.
16311 (Finsert_file_contents, Fwrite_region): Use it.
16312 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
16314 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
16316 * fns.c: Don't overflow int when computing a list length.
16317 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
16318 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
16319 truncation on 64-bit hosts. Check for QUIT every
16320 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
16321 faster and is responsive enough.
16322 (Flength): Report an error instead of overflowing an integer.
16323 (Fsafe_length): Return a float if the value is not representable
16324 as a fixnum. This shouldn't happen except in contrived situations.
16325 (Fnthcdr, Fsort): Don't assume list length fits in int.
16326 (Fcopy_sequence): Don't assume vector length fits in int.
16328 * alloc.c: Check that resized vectors' lengths fit in fixnums.
16329 (header_size, word_size): New constants.
16330 (allocate_vectorlike): Don't check size overflow here.
16331 (allocate_vector): Check it here instead, since this is the only
16332 caller of allocate_vectorlike that could cause overflow.
16333 Check that the new vector's length is representable as a fixnum.
16335 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
16336 The previous code was bogus. For example, next_almost_prime (32)
16337 returned 39, which is undesirable as it is a multiple of 3; and
16338 next_almost_prime (24) returned 25, which is a multiple of 5 so
16339 why was the code bothering to check for multiples of 7?
16341 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
16343 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
16345 Variadic C functions now count arguments with ptrdiff_t.
16346 This partly undoes my 2011-03-30 change, which replaced int with size_t.
16347 Back then I didn't know that the Emacs coding style prefers signed int.
16348 Also, in the meantime I found a few more instances where arguments
16349 were being counted with int, which may truncate counts on 64-bit
16350 machines, or EMACS_INT, which may be unnecessarily wide.
16351 * lisp.h (struct Lisp_Subr.function.aMANY)
16352 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
16353 Arg counts are now ptrdiff_t, not size_t.
16354 All variadic functions and their callers changed accordingly.
16355 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
16356 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
16357 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
16358 * callint.c (Fcall_interactively): Check arg count for overflow,
16359 to avoid potential buffer overrun. Use signed char, not 'int',
16360 for 'varies' array, so that we needn't bother to check its size
16361 calculation for overflow.
16362 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
16363 * eval.c (apply_lambda):
16364 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
16365 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
16366 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
16368 * callint.c (Fcall_interactively): Don't use index var as event count.
16370 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
16371 * mem-limits.h (SIZE): Remove; no longer used.
16373 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
16375 Remove unnecessary casts.
16376 * xterm.c (x_term_init):
16377 * xfns.c (x_set_border_pixel):
16378 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
16379 These aren't needed now that we assume ANSI C.
16381 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
16382 It's more likely to cause problems (due to unsigned overflow)
16385 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
16387 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
16389 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
16391 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
16393 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
16395 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
16397 GLYPH_CODE_FACE returns EMACS_INT, not int.
16398 * dispextern.h (merge_faces):
16399 * xfaces.c (merge_faces):
16400 * xdisp.c (get_next_display_element, next_element_from_display_vector):
16401 Don't assume EMACS_INT fits in int.
16403 * character.h (CHAR_VALID_P): Remove unused parameter.
16404 * fontset.c, lisp.h, xdisp.c: All uses changed.
16406 * editfns.c (Ftranslate_region_internal): Omit redundant test.
16408 * fns.c (concat): Minor tuning based on overflow analysis.
16409 This doesn't fix any bugs. Use int to hold character, instead
16410 of constantly refetching from Emacs object. Use XFASTINT, not
16411 XINT, for value known to be a character. Don't bother comparing
16412 a single byte to 0400, as it's always less.
16414 * floatfns.c (Fexpt):
16415 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
16417 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
16420 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
16422 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
16423 Without this fix, on a 64-bit host (aset S 0 4294967386) would
16424 incorrectly succeed when S was a string, because 4294967386 was
16425 truncated before it was used.
16427 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
16428 Otherwise, an out-of-range integer could cause undefined behavior
16431 * composite.c: Use int, not EMACS_INT, for characters.
16432 (fill_gstring_body, composition_compute_stop_pos): Use int, not
16433 EMACS_INT, for values that are known to be in character range.
16434 This doesn't fix any bugs but is the usual style inside Emacs and
16435 may generate better code on 32-bit machines.
16437 Make sure a 64-bit char is never passed to ENCODE_CHAR.
16438 This is for reasons similar to the recent CHAR_STRING fix.
16439 * charset.c (Fencode_char): Check that character arg is actually
16440 a character. Pass an int to ENCODE_CHAR.
16441 * charset.h (ENCODE_CHAR): Verify that the character argument is no
16442 wider than 'int', as a compile-time check to prevent future regressions
16445 * character.c (char_string): Remove unnecessary casts.
16447 Make sure a 64-bit char is never passed to CHAR_STRING.
16448 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
16449 by silently ignoring the top 32 bits, allowing some values
16450 that were far too large to be valid characters.
16451 * character.h: Include <verify.h>.
16452 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
16453 arguments are no wider than unsigned, as a compile-time check
16454 to prevent future regressions in this area.
16456 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
16457 (Fsubst_char_in_region):
16459 * xdisp.c (decode_mode_spec_coding):
16460 Adjust to CHAR_STRING's new requirement.
16461 * editfns.c (Finsert_char, Fsubst_char_in_region):
16462 * fns.c (concat): Check that character args are actually
16463 characters. Without this test, these functions did the wrong
16464 thing with wildly out-of-range values on 64-bit hosts.
16466 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
16467 These casts should not be needed on 32-bit hosts, either.
16468 * keyboard.c (read_char):
16469 * lread.c (Fload): Remove casts to unsigned.
16471 * lisp.h (UNSIGNED_CMP): New macro.
16472 This fixes comparison bugs on 64-bit hosts.
16473 (ASCII_CHAR_P): Use it.
16474 * casefiddle.c (casify_object):
16475 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
16476 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
16477 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
16478 * dispextern.h (FACE_FROM_ID):
16479 * keyboard.c (read_char): Use UNSIGNED_CMP.
16481 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
16482 not to EMACS_INT, to avoid GCC warning.
16484 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
16486 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
16487 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
16488 isn't needed on 32-bit machines.
16490 * buffer.c (Fgenerate_new_buffer_name):
16491 Use EMACS_INT for count, not int.
16492 (advance_to_char_boundary): Return EMACS_INT, not int.
16494 * data.c (Qcompiled_function): Now static.
16496 * window.c (window_body_lines): Now static.
16498 * image.c (gif_load): Rename local to avoid shadowing.
16500 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
16501 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
16502 * alloc.c (make_save_value): Integer argument is now of type
16503 ptrdiff_t, not int.
16504 (mark_object): Use ptrdiff_t, not int.
16505 * lisp.h (pD): New macro.
16506 * print.c (print_object): Use it.
16508 * alloc.c: Use EMACS_INT, not int, to count objects.

16538 (allocate_string_data): Check for string overflow. This catches
16539 some instances we weren't catching before. Also, it catches
16540 size_t overflow on (unusual) hosts where SIZE_MAX <= min
16541 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
16542 and ptrdiff_t and EMACS_INT are both 64 bits.
16544 * character.c, coding.c, doprnt.c, editfns.c, eval.c:

17050 * alloc.c (memory_full) [SYSTEM_MALLOC]: Port to MacOS (Bug#8800).
17051 Do not assume that spare memory exists; that assumption is valid
17052 only if SYSTEM_MALLOC.
17053 (LARGE_REQUEST): New macro, so that the issue of large requests
17054 is separated from the issue of spare memory.

17123 instead of using explicit *_CHAR codes.
17124 (bidi_resolve_explicit, bidi_resolve_weak):

17133 (bidi_level_of_next_char): Don't try to lookup the cache for the
17134 next/previous character if nothing is cached there yet, or if we
17135 were just reseat()'ed to a new position.
17137 * xdisp.c (set_cursor_from_row): Set start and stop points
17138 according to the row's direction when priming the loop that looks
17139 for the glyph on which to display cursor.

17141 (display_prop_intangible_p): Reimplement to call
17142 handle_display_spec instead of single_display_spec_intangible_p.
17143 Accept 3 additional arguments needed by handle_display_spec.
17144 This fixes incorrect cursor motion across display property with complex
17145 values: lists, `(when COND...)' forms, etc.

17147 lists with the argument STRING its top-level element.
17148 (display_prop_string_p): Fix the condition for processing a

17152 (compute_display_string_pos): Accept additional argument
17153 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
17154 value of a `display' property is a "replacing spec".
17155 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
17156 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
17157 the display property, but just return a value indicating whether
17158 the display property will replace the characters it covers.
17159 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
17160 frame_window_p members of struct bidi_it.
17161 (compute_display_string_pos, compute_display_string_end):

17167 * keyboard.c (adjust_point_for_property): Adjust the call to
17168 display_prop_intangible_p to its new signature.

17184 All callers changed. (Bug#8762)
17186 * gnutls.c: Use Emacs's memory allocators.
17187 Without this change, the gnutls library would invoke malloc etc.
17188 directly, which causes problems on non-SYNC_INPUT hosts, and which
17189 runs afoul of improving memory_full behavior. (Bug#8761)
17190 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
17191 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
17192 xfree instead of the default malloc, realloc, free.
17193 (Fgnutls_boot): No need to check for memory allocation failure,
17194 since xmalloc does that for us.
17196 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
17197 * category.c (hash_get_category_set):

17216 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
17217 for hashes and hash indexes, instead of 'unsigned' and 'int'.
17218 * alloc.c (allocate_vectorlike):
17219 Check for overflow in vector size calculations.
17220 * ccl.c (ccl_driver):
17221 Check for overflow when converting EMACS_INT to int.

17223 need to be updated by these changes.
17224 * fns.c (make_hash_table, maybe_resize_hash_table):
17225 Check for integer overflow with large hash tables.
17226 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
17227 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
17228 (SXHASH_REDUCE): New macro.
17229 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
17230 Use it instead of discarding useful hash info with large hash values.
17231 (sxhash_float): New function.
17232 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
17233 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
17234 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
17235 Rewrite to use FIXNUM_BITS, as this simplifies things.
17236 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
17237 Adjust signatures to match updated version of code.
17238 (consing_since_gc): Now EMACS_INT, since a single hash table can
17239 use more than INT_MAX bytes.

17288 Make it possible to run ./temacs.
17290 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
17291 syms_of_callproc does the same thing. Remove test for

17352 * fns.c (to_uchar): Define.
17353 (crypto_hash_function): Use it to convert some newly-signed
17354 variables to unsigned, to avoid sign-extension bugs. For example,
17355 without this change, (md5 "truc") would evaluate to
17356 45723a2aff78ff4fff7fff1114760e62 rather than the expected
17357 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in

17370 that was so large that it became a float. (Bug#8722)
17372 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
17373 (Fdbus_call_method, Fdbus_call_method_asynchronously):
17374 Use XFASTINT rather than XUINT when numbers are nonnegative.
17375 (xd_append_arg, Fdbus_method_return_internal):
17376 (Fdbus_method_error_internal): Likewise. Also, for unsigned
17377 arguments, check that Lisp number is nonnegative, rather than
17378 silently wrapping negative numbers around. (Bug#8722)
17379 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
17382 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
17384 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
17386 ccl: Add integer overflow checks.
17387 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
17388 (IN_INT_RANGE): New macros.
17389 (ccl_driver): Use them to check for integer overflow when
17390 decoding a CCL program. Many of the new checks are whether XINT (x)
17391 fits in int; it doesn't always, on 64-bit hosts. The new version
17392 doesn't catch all possible integer overflows, but it's an
17393 improvement. (Bug#8719)
17395 * alloc.c (make_event_array): Use XINT, not XUINT.
17396 There's no need for unsigned here.
17398 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
17399 This follows up to the 2011-05-06 change that substituted uintptr_t
17400 for EMACS_INT. This case wasn't caught back then.
17402 Rework Fformat to avoid integer overflow issues.
17403 * editfns.c: Include <float.h> unconditionally, as it's everywhere
17404 now (part of C89). Include <verify.h>.
17405 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
17406 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
17407 (Fformat): Avoid the prepass trying to compute sizes; it was only
17408 approximate and thus did not catch overflow reliably. Instead, walk
17409 through the format just once, formatting and computing sizes as we go,
17410 checking for integer overflow at every step, and allocating a larger
17411 buffer as needed. Keep track separately whether the format is
17412 multibyte. Keep only the most-recently calculated precision, rather
17413 than them all. Record whether each argument has been converted to
17414 string. Use EMACS_INT, not int, for byte and char and arg counts.
17415 Support field widths and precisions larger than INT_MAX. Avoid
17416 sprintf's undefined behavior with conversion specifications such as %#d
17417 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
17418 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
17419 formatting out-of-range floating point numbers with int
17420 formats. (Bug#8668)
17422 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
17424 * data.c: Avoid integer truncation in expressions involving floats.
17425 * data.c: Include <intprops.h>.
17426 (arith_driver): When there's an integer overflow in an expression
17427 involving floating point, convert the integers to floating point
17428 so that the resulting value does not suffer from catastrophic
17429 integer truncation. For example, on a 64-bit host (* 4
17430 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
17431 Do not rely on undefined behavior after integer overflow.
17433 merge count_size_as_multibyte, parse_str_to_multibyte
17434 * character.c, character.h (count_size_as_multibyte):
17435 Rename from parse_str_to_multibyte; all uses changed.
17436 Check for integer overflow.
17437 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
17438 since it's now a duplicate of the other. This is more of
17439 a character than a buffer op, so better that it's in character.c.
17440 * fns.c, print.c: Adjust to above changes.
17442 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
17444 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
17446 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
17448 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
17449 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
17450 (x_clipboard_manager_save): Now static.
17451 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
17453 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
17454 (crypto_hash_function): Now static.
17455 Fix pointer signedness problems. Avoid unnecessary initializations.
17457 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
17459 * termhooks.h (Vselection_alist): Make it terminal-local.
17461 * terminal.c (create_terminal): Initialize it.
17463 * xselect.c: Support for clipboard managers.
17464 (Vselection_alist): Move to termhooks.h as terminal-local var.
17465 (LOCAL_SELECTION): New macro.
17466 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
17467 (symbol_to_x_atom): Remove gratuitous arg.
17468 (x_handle_selection_request, lisp_data_to_selection_data)
17469 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
17470 (x_own_selection, x_get_local_selection, x_convert_selection):
17471 New arg, specifying work frame. Use terminal-local Vselection_alist.
17472 (some_frame_on_display): Delete unused function.
17473 (Fx_own_selection_internal, Fx_get_selection_internal)
17474 (Fx_disown_selection_internal, Fx_selection_owner_p)
17475 (Fx_selection_exists_p): New optional frame arg.
17476 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
17477 (x_handle_selection_clear): Don't treat other terminals with the
17478 same keyboard specially. Use the terminal-local Vselection_alist.
17479 (x_clear_frame_selections): Use Frun_hook_with_args.
17481 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
17483 * xterm.h: Add support for those atoms.
17485 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
17487 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
17488 (converted_selections, conversion_fail_tag): New global variables.
17489 (x_selection_request_lisp_error): Free the above.
17490 (x_get_local_selection): Remove unnecessary code.
17491 (x_reply_selection_request): Args changed; handle arbitrary array
17492 of converted selections stored in converted_selections.
17493 Separate the XChangeProperty and SelectionNotify steps.
17494 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
17495 (x_convert_selection): New function.
17496 (x_handle_selection_event): Simplify.
17497 (x_get_foreign_selection): Don't ignore incoming requests while
17498 waiting for an answer; this will fail when we implement
17499 SAVE_TARGETS, and seems unnecessary anyway.
17500 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
17501 (Vx_sent_selection_functions): Doc fix.
17503 2011-05-26 Leo Liu <sdl.web@gmail.com>
17505 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
17507 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17509 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
17511 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
17512 for fringe update if it has periodic bitmap.
17513 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
17514 and fringe_bitmap_periodic_p.
17516 * fringe.c (get_fringe_bitmap_data): New function.
17517 (draw_fringe_bitmap_1, update_window_fringes): Use it.
17518 (update_window_fringes): Record periodicity of fringe bitmap in glyph
17519 row. Mark glyph row for fringe update if periodicity changed.
17521 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
17522 for fringe update unless it has periodic bitmap.
17524 2011-05-25 Kenichi Handa <handa@m17n.org>
17526 * xdisp.c (get_next_display_element): Set correct it->face_id for
17527 a static composition.
17529 2011-05-24 Leo Liu <sdl.web@gmail.com>
17532 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
17534 * fns.c (crypto_hash_function, Fsha1): New function.
17535 (Fmd5): Use crypto_hash_function.
17536 (syms_of_fns): Add Ssha1.
17538 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
17540 * gnutls.c: Remove unused macros.
17541 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
17542 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
17543 Remove macros that are defined and never used.
17544 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
17546 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
17548 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
17549 (Fx_get_selection_internal): Minor cleanup.
17550 (Fx_own_selection_internal): Rename arguments for consistency with
17553 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
17555 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
17557 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
17559 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
17561 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17563 * dispnew.c (scrolling_window): Don't exclude the case that the
17564 last enabled row in the desired matrix touches the bottom boundary.
17566 2011-05-21 Glenn Morris <rgm@gnu.org>
17568 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
17569 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
17570 and add some more files.
17572 2011-05-20 Eli Zaretskii <eliz@gnu.org>
17574 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
17575 report_file_error introduced by the change from 2011-05-07.
17577 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
17579 * systime.h (Time): Define only if emacs is defined.
17580 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
17581 where the include path doesn't have X11/X.h by default. See
17582 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
17584 2011-05-20 Kenichi Handa <handa@m17n.org>
17586 * composite.c (find_automatic_composition): Fix previous change.
17588 2011-05-20 Glenn Morris <rgm@gnu.org>
17590 * lisp.mk: New file, split from Makefile.in.
17591 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
17592 (shortlisp): Remove.
17593 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
17595 2011-05-19 Glenn Morris <rgm@gnu.org>
17597 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
17598 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
17599 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
17600 (lisp): Set the order to that of loadup.el.
17601 (shortlisp): Make it a copy of $lisp.
17602 (SOME_MACHINE_LISP): Remove.
17603 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
17604 Use just $shortlisp, not $SOME_MACHINE_LISP too.
17606 2011-05-18 Kenichi Handa <handa@m17n.org>
17608 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
17609 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
17610 (find_automatic_composition): Mostly rewrite for efficiency.
17612 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
17614 * makefile.w32-in: Update dependencies.
17616 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
17618 * menu.c: Include limits.h (fixes the MS-Windows build broken by
17619 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
17621 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
17623 Fix some integer overflow issues, such as string length overflow.
17625 * insdel.c (count_size_as_multibyte): Check for string overflow.
17627 * character.c (lisp_string_width): Check for string overflow.
17628 Use EMACS_INT, not int, for string indexes and lengths; in
17629 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
17630 the resulting string length overflows an EMACS_INT; instead,
17631 report a string overflow if no precision given. When checking for
17632 precision exhaustion, use a check that cannot possibly have
17633 integer overflow. (Bug#8675)
17634 * character.h (lisp_string_width): Adjust to new signature.
17636 * alloc.c (string_overflow): New function.
17637 (Fmake_string): Use it. This doesn't change behavior, but saves
17638 a few bytes and will simplify future changes.
17639 * character.c (string_escape_byte8): Likewise.
17640 * lisp.h (string_overflow): New decl.
17642 Fixups, following up to the user-interface timestamp change.
17643 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
17644 for UI timestamps, instead of unsigned long.
17645 * msdos.c (mouse_get_pos): Likewise.
17646 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
17647 * w32gui.h (Time): Define by including "systime.h" rather than by
17648 declaring it ourselves. (Bug#8664)
17650 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
17651 * image.c (clear_image_cache): Likewise.
17653 * term.c (term_mouse_position): Don't assume time_t wraparound.
17655 Be more systematic about user-interface timestamps.
17656 Before, the code sometimes used 'Time', sometimes 'unsigned long',
17657 and sometimes 'EMACS_UINT', to represent these timestamps.
17658 This change causes it to use 'Time' uniformly, as that's what X uses.
17659 This makes the code easier to follow, and makes it easier to catch
17660 integer overflow bugs such as Bug#8664.
17661 * frame.c (Fmouse_position, Fmouse_pixel_position):
17662 Use Time, not unsigned long, for user-interface timestamps.
17663 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
17664 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
17665 * keyboard.h (last_event_timestamp): Likewise.
17666 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
17667 * menu.h (xmenu_show): Likewise.
17668 * term.c (term_mouse_position): Likewise.
17669 * termhooks.h (struct input_event.timestamp): Likewise.
17670 (struct terminal.mouse_position_hook): Likewise.
17671 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
17672 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
17673 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
17674 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
17675 what it was before.
17676 * menu.h, termhooks.h: Include "systime.h", for Time.
17678 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
17679 Don't assume that the difference between two unsigned long values
17680 can fit into an integer. At this point, we know button_down_time
17681 <= event->timestamp, so the difference must be nonnegative, so
17682 there's no need to cast the result if double-click-time is
17683 nonnegative, as it should be; check that it's nonnegative, just in
17684 case. This bug is triggered when events are more than 2**31 ms
17685 apart (about 25 days). (Bug#8664)
17687 * xselect.c (last_event_timestamp): Remove duplicate decl.
17688 (x_own_selection): Remove needless cast to unsigned long.
17690 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
17691 that always fit in int. Use a sentinel instead of a counter, to
17692 avoid a temp and to allay GCC's concerns about possible int overflow.
17693 * frame.h (struct frame): Use int for menu_bar_items_used
17694 instead of EMACS_INT, since it always fits in int.
17696 * menu.c (grow_menu_items): Check for int overflow.
17698 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
17700 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
17701 Before, the code was not consistent. These values cannot exceed
17702 2**31 - 1 so there's no need to make them unsigned.
17703 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
17704 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
17705 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
17707 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
17709 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
17710 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
17711 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
17712 presumably because the widths might not match.
17714 * window.c (size_window): Avoid needless test at loop start.
17716 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
17718 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
17720 2011-05-12 Drew Adams <drew.adams@oracle.com>
17722 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
17724 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17726 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
17727 `width' to `bar_area_x' and `bar_area_width', respectively.
17728 (x_scroll_run): Take account of fringe background extension.
17730 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
17731 Rename local vars `left' and `width' to `bar_area_x' and
17732 `bar_area_width', respectively.
17733 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
17734 background extension.
17736 2011-05-10 Jim Meyering <meyering@redhat.com>
17738 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
17740 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
17742 * image.c (Finit_image_library): Return t for built-in image types,
17743 like pbm and xbm. (Bug#8640)
17745 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
17747 * w32menu.c (set_frame_menubar): Fix submenu allocation.
17749 2011-05-07 Eli Zaretskii <eliz@gnu.org>
17751 * w32console.c (Fset_screen_color): Doc fix.
17752 (Fget_screen_color): New function.
17753 (syms_of_ntterm): Defsubr it.
17755 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
17756 unlink the temporary file if Fcall_process didn't create it in the
17758 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
17759 child process will be redirected to a file specified with `:file'.
17760 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
17761 cue to call_process_cleanup not to close that handle.
17763 2011-05-07 Ben Key <bkey76@gmail.com>
17765 * makefile.w32-in: The bootstrap-temacs rule now makes use of
17766 one of two shell specific rules, either bootstrap-temacs-CMD or
17767 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
17768 to the previous implementation of the bootstrap-temacs rule.
17769 The bootstrap-temacs-CMD rule is similar to the previous
17770 implementation of the bootstrap-temacs rule except that it
17771 makes use of the ESC_CFLAGS variable instead of the CFLAGS
17774 These changes, along with some changes to nt/configure.bat,
17775 nt/gmake.defs, and nt/nmake.defs, are required to extend my
17776 earlier fix to add support for --cflags and --ldflags options
17777 that include quotes so that it works whether make uses cmd or
17780 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
17782 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
17783 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
17785 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
17786 a string. Handle both cases.
17787 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
17788 (Fdbus_register_method): Use Qinvalid_function.
17790 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
17792 * makefile.w32-in: Update dependencies.
17793 (LISP_H): Add inttypes.h and stdin.h.
17794 (PROCESS_H): Add unistd.h.
17796 2011-05-06 Eli Zaretskii <eliz@gnu.org>
17798 * lread.c: Include limits.h (fixes the MS-Windows build broken by
17799 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
17801 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
17803 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
17805 * term.c (vfatal): Remove stray call to va_end.
17806 It's not needed and the C Standard doesn't allow it here anyway.
17808 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
17809 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
17811 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
17814 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
17816 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
17818 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
17820 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
17822 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
17824 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
17825 * charset.c (Fdefine_charset_internal): Don't initialize
17826 charset.code_space[15]. The value was garbage, on hosts with
17827 32-bit int (Bug#8600).
17829 * lread.c (read_integer): Be more consistent with string-to-number.
17830 Use string_to_number to do the actual conversion; this avoids
17831 rounding errors and fixes some other screwups. Without this fix,
17832 for example, #x1fffffffffffffff was misread as -2305843009213693952.
17833 (digit_to_number): Move earlier, for benefit of read_integer.
17834 Return -1 if the digit is out of range for the base, -2 if it is
17835 not a digit in any supported base. (Bug#8602)
17837 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
17839 * dispnew.c (scrolling_window): Return 1 if we scrolled,
17840 to match comment at start of function. This also removes a
17841 GCC warning about overflow in a 32+64-bit port.
17843 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
17845 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
17846 Reported by Stefan Monnier in
17847 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
17848 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
17849 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
17851 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
17852 (EMACS_UINTPTR): Likewise, with uintptr_t.
17854 * lisp.h: Prefer 64-bit EMACS_INT if available.
17855 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
17856 on 32-bit hosts that have 64-bit int, so that they can access
17858 However, temporarily disable this change unless the temporary
17859 symbol WIDE_EMACS_INT is defined.
17861 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
17863 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
17864 This removes an assumption that EMACS_INT and long are the same
17865 width as pointers. The assumption is true for Emacs porting targets
17866 now, but we want to make other targets possible.
17867 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
17868 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
17869 In the rest of the code, change types of integers that hold casted
17870 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
17871 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
17872 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
17873 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
17874 No need to cast type when ORing.
17875 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
17876 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
17877 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
17878 assume EMACS_INT is the same width as char *.
17879 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
17880 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
17881 Remove no-longer-needed casts.
17882 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
17883 (xg_tool_bar_help_callback, xg_make_tool_item):
17884 Use EMACS_INTPTR to hold an integer
17885 that will be cast to void *; this can avoid a GCC warning
17886 if EMACS_INT is not the same width as void *.
17887 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
17888 * xdisp.c (display_echo_area_1, resize_mini_window_1):
17889 (current_message_1, set_message_1):
17890 Use a local to convert to proper width without a cast.
17891 * xmenu.c (dialog_selection_callback): Likewise.
17893 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
17894 Also, don't assume VALBITS / RAND_BITS is less than 5,
17895 and don't rely on undefined behavior when shifting a 1 left into
17897 * lisp.h (get_random): Change signature to match.
17899 * lread.c (hash_string): Use size_t, not int, for hash computation.
17900 Normally we prefer signed values; but hashing is special, because
17901 it's better to use unsigned division on hash table sizes so that
17902 the remainder is nonnegative. Also, size_t is the natural width
17903 for hashing into memory. The previous code used 'int', which doesn't
17904 retain enough info to hash well into very large tables.
17905 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
17907 * dbusbind.c: Don't possibly lose pointer info when converting.
17908 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
17909 Use XPNTR rather than XHASH, so that the high-order bits of
17910 the pointer aren't lost when converting through void *.
17912 * eval.c (Fautoload): Don't double-shift a pointer.
17914 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
17916 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
17918 * gnutls.c (DEF_GNUTLS_FN):
17919 * image.c (DEF_IMGLIB_FN): Make function pointers static.
17921 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
17923 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
17926 2011-05-05 Eli Zaretskii <eliz@gnu.org>
17928 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
17929 New version that can reserve upto 2GB of heap space.
17931 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
17933 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
17935 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
17937 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
17938 `gnutls_certificate_set_x509_key_file'.
17940 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
17942 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
17943 Update dependencies.
17945 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
17947 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
17948 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
17949 Remove unused parameter `fildes'.
17950 * process.c (read_process_output, send_process): Don't pass it.
17952 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
17954 Fix previous change: the library cache is defined in w32.c.
17955 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
17956 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
17958 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
17960 Implement dynamic loading of GnuTLS on Windows.
17962 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
17963 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
17964 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
17967 * gnutls.c (Qgnutls_dll): Define.
17968 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
17969 (gnutls_*): Declare function pointers.

17973 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
17974 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
17975 (emacs_gnutls_write, emacs_gnutls_read)
17976 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
17977 (Fgnutls_available_p): New function.
17978 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.

17988 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
17990 * w32.c (QCloaded_from, Vlibrary_cache): Define.
17991 (w32_delayed_load): Move from image.c. When loading a library, record
17992 its filename in the :loaded-from property of the library id.
17993 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
17994 Initialize and staticpro them.
17995 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
17997 * process.c: Include lisp.h before w32.h, not after.
17998 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
17999 instead of gnutls_record_check_pending.
18001 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
18003 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
18005 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
18006 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
18009 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
18011 * xterm.c (x_set_frame_alpha): Do not set property on anything
18012 else than FRAME_X_OUTER_WINDOW (Bug#8608).
18014 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
18016 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
18018 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
18020 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)

18034 * sysdep.c (wait_for_termination_1): Make static.
18035 (wait_for_termination, interruptible_wait_for_termination):
18036 Move after wait_for_termination_1.
18038 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
18040 * sysdep.c (interruptible_wait_for_termination): New function
18041 which is like wait_for_termination, but allows keyboard
18044 * callproc.c (Fcall_process): Add (:file "file") as an option for
18046 (Fcall_process_region): Ditto.
18048 2011-04-30 Eli Zaretskii <eliz@gnu.org>
18050 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
18051 rather than `XVECTOR (FOO)->size'.
18053 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
18054 inttypes.h, as a gnulib replacement is used if it not available in
18057 2011-04-21 Eli Zaretskii <eliz@gnu.org>
18059 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
18060 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
18061 of MOST_POSITIVE_FIXNUM. (Bug#8528)
18063 * coding.c (coding_alloc_by_realloc): Error out if destination
18064 will grow beyond MOST_POSITIVE_FIXNUM.
18065 (decode_coding_emacs_mule): Abort if there isn't enough place in
18066 charbuf for the composition carryover bytes. Reserve an extra
18067 space for up to 2 characters produced in a loop.
18068 (decode_coding_iso_2022): Abort if there isn't enough place in
18069 charbuf for the composition carryover bytes.
18071 2011-04-21 Eli Zaretskii <eliz@gnu.org>
18073 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
18074 aborting when %lld or %lll format is passed.
18075 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
18076 %llo or %llx format is passed. (Bug#8545)
18078 * window.c (window_scroll_line_based): Use a marker instead of
18079 simple variables to record original value of point. (Bug#7952)
18081 * doprnt.c (doprnt): Fix the case where a multibyte sequence
18082 produced by %s or %c overflows available buffer space. (Bug#8545)
18084 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
18086 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).

18096 (command_loop_1): Run `delayed-warnings-hook'
18097 if Vdelayed_warnings_list is non-nil.
18098 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
18099 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
18101 2011-04-28 Eli Zaretskii <eliz@gnu.org>
18103 * doprnt.c (doprnt): Don't return value smaller than the buffer
18104 size if the message was truncated. (Bug#8545).
18106 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
18108 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)

18111 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
18113 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
18115 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
18117 * makefile.w32-in: Update dependencies.
18119 2011-04-27 Eli Zaretskii <eliz@gnu.org>
18121 Improve `doprnt' and its usage. (Bug#8545)
18122 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
18123 `format_end'. Remove support for %l as a conversion specifier.
18124 Don't use xrealloc. Improve diagnostics when the %l size modifier
18125 is used. Update the commentary.
18127 * eval.c (verror): Simplify calculation of size_t.
18129 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
18132 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
18134 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
18137 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
18139 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
18140 This makes this file independent of the recent pseudovector change.
18142 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
18144 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
18146 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
18147 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
18148 Remove unused local.
18149 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
18151 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
18152 GCC 4.6.0 optimizes based on type-based alias analysis.
18153 For example, if b is of type struct buffer * and v of type struct
18154 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
18155 != &v->size, and therefore "v->size = 1; b->size = 2; return
18156 v->size;" must therefore return 1. This assumption is incorrect
18157 for Emacs, since it type-puns struct Lisp_Vector * with many other
18158 types. To fix this problem, this patch adds a new type struct
18159 vectorlike_header that documents the constraints on layout of vectors
18160 and pseudovectors, and helps optimizing compilers not get fooled
18161 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
18162 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
18163 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
18165 (XSETPVECTYPE): Rewrite in terms of new macro.
18166 (XSETPVECTYPESIZE): New macro, specifying both type and size.
18167 This is a bit clearer, and further avoids the possibility of
18168 undesirable aliasing.
18169 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
18170 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
18171 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
18172 since Lisp_Subr is a special case (no "next" field).
18173 (ASIZE): Now uses header.size rather than size.
18174 All previous uses of XVECTOR (foo)->size replaced to use this macro,
18175 to avoid the hassle of writing XVECTOR (foo)->header.size.
18176 (struct vectorlike_header): New type.
18177 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
18178 object, to help avoid aliasing.
18179 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
18180 (SUBRP): Likewise, since Lisp_Subr is a special case.
18181 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
18182 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
18183 (struct Lisp_Hash_Table): Combine first two members into a single
18184 struct vectorlike_header member. All uses of "size" and "next" members
18185 changed to be "header.size" and "header.next".
18186 * buffer.h (struct buffer): Likewise.
18187 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
18188 * frame.h (struct frame): Likewise.
18189 * process.h (struct Lisp_Process): Likewise.
18190 * termhooks.h (struct terminal): Likewise.
18191 * window.c (struct save_window_data, struct saved_window): Likewise.
18192 * window.h (struct window): Likewise.
18193 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
18194 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
18195 * buffer.c (init_buffer_once): Likewise.
18196 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
18198 * process.c (Fformat_network_address): Use local var for size,
18201 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
18203 Make the Lisp reader and string-to-float more consistent (Bug#8525)
18204 * data.c (atof): Remove decl; no longer used or needed.
18205 (digit_to_number): Move to lread.c.
18206 (Fstring_to_number): Use new string_to_number function, to be
18207 consistent with how the Lisp reader treats infinities and NaNs.
18208 Do not assume that floating-point numbers represent EMACS_INT
18209 without losing information; this is not true on most 64-bit hosts.
18210 Avoid double-rounding errors, by insisting on integers when
18211 parsing non-base-10 numbers, as the documentation specifies.
18212 * lisp.h (string_to_number): New decl, replacing ...
18213 (isfloat_string): Remove.
18214 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
18215 (read1): Do not accept +. and -. as integers; this
18216 appears to have been a coding error. Similarly, do not accept
18217 strings like +-1e0 as floating point numbers. Do not report
18218 overflow for integer overflows unless the base is not 10 which
18219 means we have no simple and reliable way to continue.
18220 Break out the floating-point parsing into a new
18221 function string_to_number, so that Fstring_to_number parses
18222 floating point numbers consistently with the Lisp reader.
18223 (digit_to_number): Move here from data.c. Make it static inline.
18224 (E_CHAR, EXP_INT): Remove, replacing with ...
18225 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
18226 (string_to_number): New function, replacing isfloat_string.
18227 This function checks for valid syntax and produces the resulting
18228 Lisp float number too. Rework it so that string-to-number
18229 no longer mishandles examples like "1.0e+". Use strtoumax,
18230 so that overflow for non-base-10 numbers is reported only when
18231 there's no portable and simple way to convert to floating point.
18233 * textprop.c (set_text_properties_1): Rewrite for clarity,
18234 and to avoid GCC warning about integer overflow.
18236 * intervals.h (struct interval): Use EMACS_INT for members
18237 where EMACS_UINT might cause problems. See
18238 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
18239 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
18240 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
18242 (offset_intervals): Tell GCC not to worry about length overflow
18243 when negating a negative length.
18245 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
18246 (overrun_check_free): Likewise.
18248 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
18249 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
18252 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
18253 (gnutls_make_error): Rename local to avoid shadowing.
18254 (gnutls_emacs_global_deinit): ifdef out; not used.
18255 (Fgnutls_boot): Use const for pointer to readonly storage.
18256 Comment out unused local. Fix pointer signedness problems.
18258 * lread.c (openp): Don't stuff size_t into an 'int'.
18259 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
18260 about possible signed overflow.
18262 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
18263 (GDK_KEY_g): Don't define if already defined.
18264 (xg_prepare_tooltip): Avoid pointer signedness problem.
18265 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
18267 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
18268 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
18270 * xfns.c (Fx_window_property): Simplify a bit,
18271 to make a bit faster and to avoid GCC 4.6.0 warning.
18272 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
18274 * fns.c (internal_equal): Don't assume size_t fits in int.
18276 * alloc.c (compact_small_strings): Tighten assertion a little.
18278 Replace pEd with more-general pI, and fix some printf arg casts.
18279 * lisp.h (pI): New macro, generalizing old pEd macro to other
18280 conversion specifiers. For example, use "...%"pI"d..." rather
18281 than "...%"pEd"...".
18282 (pEd): Remove. All uses replaced with similar uses of pI.
18283 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
18284 * alloc.c (check_pure_size): Don't overflow by converting size to int.
18285 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
18286 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.

18288 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
18289 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
18291 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
18292 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
18293 * print.c (safe_debug_print, print_object): Likewise.
18294 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
18296 Use pI instead of if-then-else-abort. Use %p to avoid casts,
18297 avoiding the 0 flag, which is not portable.
18298 * process.c (Fmake_network_process): Use pI to avoid cast.
18299 * region-cache.c (pp_cache): Likewise.
18300 * xdisp.c (decode_mode_spec): Likewise.
18301 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
18302 behavior on 64-bit hosts with printf arg.
18303 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
18304 (x_stop_queuing_selection_requests): Likewise.
18305 (x_get_window_property): Don't truncate byte count to an 'int'
18308 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
18309 here, since it parses constructs like leading '-' and spaces,
18310 which are not wanted; and it overflows with large numbers.
18311 Instead, simply match F[0-9]+, which is what is wanted anyway.
18313 * alloc.c: Remove unportable assumptions about struct layout.
18314 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
18315 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
18316 (allocate_vectorlike, make_pure_vector): Use the new macros,
18317 plus offsetof, to remove unportable assumptions about struct layout.
18318 These assumptions hold on all porting targets that I know of, but
18319 they are not guaranteed, they're easy to remove, and removing them
18320 makes further changes easier.
18322 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
18323 This doesn't fix a bug but makes the code clearer.
18324 (string_overrun_cookie): Now const. Use initializers that
18325 don't formally overflow signed char, to avoid warnings.
18326 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
18327 can cause Emacs to crash when string overrun checking is enabled.
18328 (allocate_buffer): Don't assume sizeof (struct buffer) is a
18329 multiple of sizeof (EMACS_INT); it need not be, if
18330 alignof(EMACS_INT) < sizeof (EMACS_INT).
18331 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
18333 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

18360 2011-04-25 Eli Zaretskii <eliz@gnu.org>
18362 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
18363 "cast to pointer from integer of different size".
18365 Improve doprnt and its use in verror. (Bug#8545)
18366 * doprnt.c (doprnt): Document the set of format control sequences
18367 supported by the function. Use SAFE_ALLOCA instead of always
18370 * eval.c (verror): Don't limit the buffer size at size_max-1, that
18371 is one byte too soon. Don't use xrealloc; instead xfree and
18374 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
18376 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the

18380 gnutls_global_initialized. Added internals for the
18381 :verify-hostname-error, :verify-error, and :verify-flags
18382 parameters of `gnutls-boot' and documented those parameters in the
18383 docstring. Start callback support.
18384 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
18385 unless a fatal error occurred. Call gnutls_alert_send_appropriate

18463 conversions. Support %l conversion. Don't assume an EMACS_INT
18464 argument for integer conversions and for %c.
18466 * lisp.h (doprnt): Restore prototype.
18468 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on

18483 * callint.c (Fcall_interactively): When displaying error message
18484 about invalid control letter, pass the character's codepoint, not

18489 codepoint of an invalid character, to avoid displaying a bogus
18492 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
18493 `error', not SYMBOL_NAME itself.

18498 * charset.c (check_iso_charset_parameter): Fix incorrect argument
18499 to `error' in error message about FINAL_CHAR argument. Make sure
18500 FINAL_CHAR is a character, and use %c when it is passed as
18501 argument to `error'.
18503 2011-04-23 Eli Zaretskii <eliz@gnu.org>
18505 * s/ms-w32.h (localtime): Redirect to sys_localtime.
18507 * w32.c: Include <time.h>.

18567 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
18568 by pacifying GCC about it. Maybe it's time to retire it?
18569 * xfaces.c (USG, __TIMEVAL__): Likewise.
18571 * dispextern.h (struct redisplay_interface): Rename param
18572 to avoid shadowing.
18573 * termhooks.h (struct terminal): Likewise.
18574 * xterm.c (xembed_send_message): Likewise.
18576 * insdel.c (make_gap_smaller): Define only if
18577 USE_MMAP_FOR_BUFFERS || REL_ALLOC || DOUG_LEA_MALLOC.
18579 * keyboard.c (read_char): Make a var volatile so longjmp won't clobber
18582 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,
18583 so that we aren't warned about unused symbols.

18620 compatible char. Avoid the old compiler warnings about
18621 out-of-range initializers by using, for example, '\xab' rather
18624 * xgselect.c (xgselect_initialize): Check vs interface
18625 even if ! (defined (USE_GTK) || defined (HAVE_GCONF)).

18674 (bcmp_translate, regcomp, regexec, print_double_string)
18675 (group_in_compile_stack, re_search, re_search_2, regex_compile)
18676 (re_compile_pattern, re_exec): Declare arguments and local
18677 variables `size_t' and `ssize_t' and return values `regoff_t', as

18685 specify buffer/string position and length are now ssize_t and
18686 size_t. Return type is regoff_t.
18688 2011-04-16 Ben Key <bkey76@gmail.com>
18690 * nsfont.m: Fixed bugs in ns_get_family and
18691 ns_descriptor_to_entity that were caused by using free to
18692 deallocate memory blocks that were allocated by xmalloc (via
18693 xstrdup). This caused Emacs to crash when compiled with
18694 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
18695 --enable-checking=xmallocoverrun). xfree is now used to
18696 deallocate these memory blocks.
18698 2011-04-15 Paul Eggert <eggert@cs.ucla.edu>
18700 * sysdep.c (emacs_read): Remove unnecessary check vs MAX_RW_COUNT.

19123 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
19124 Mark functions with DEFUE instead of DEFUN,
19125 if they are used in other modules.
19126 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
19127 decls for now-static functions.
19128 * buffer.h (Fdelete_overlay): Remove decl.
19129 * callproc.c (Fgetenv_internal): Mark as internal.

19164 2011-04-13 Eli Zaretskii <eliz@gnu.org>
19166 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
19167 when at ZV. (Bug#8487)
19169 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
19171 * charset.c (Fclear_charset_maps): Use xfree instead of free.
19173 * keyboard.c (parse_tool_bar_item): Likewise.
19174 * sound.c (sound_cleanup, alsa_close): Likewise.
19175 * termcap.c (tgetent): Likewise.
19176 * xfns.c (x_default_font_parameter): Likewise.
19177 * xsettings.c (read_and_apply_settings): Likewise.
19179 * alloc.c (overrun_check_malloc, overrun_check_realloc)
19180 (overrun_check_free): Protoize.
19182 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
19184 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
19185 since callers should never pass a negative size.
19186 Change the signature to match that of plain 'read' and 'write'; see
19187 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
19188 * lisp.h: Update prototypes of emacs_write and emacs_read.
19190 2011-04-11 Eli Zaretskii <eliz@gnu.org>
19192 * xdisp.c (redisplay_window): Don't try to determine the character
19193 position of the scroll margin if the window start point w->startp
19194 is outside the buffer's accessible region. (Bug#8468)
19196 2011-04-10 Eli Zaretskii <eliz@gnu.org>
19198 Fix write-region and its subroutines for buffers > 2GB.
19199 * fileio.c (a_write, e_write): Modify declaration of arguments and
19200 local variables to support buffers larger than 2GB.
19201 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
19203 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
19204 argument, local variables, and return value.
19206 * lisp.h: Update prototypes of emacs_write and emacs_read.
19208 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
19210 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
19212 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
19214 Fix more problems found by GCC 4.6.0's static checks.
19216 * xdisp.c (vmessage): Use a better test for character truncation.
19218 * charset.c (load_charset_map): <, not <=, for optimization,
19219 and to avoid potential problems with integer overflow.
19220 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
19221 * casetab.c (set_identity, shuffle): Likewise.
19222 * editfns.c (Fformat): Likewise.
19223 * syntax.c (skip_chars): Likewise.
19225 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
19226 This also lets GCC 4.6.0 generate slightly better loop code.
19228 * callint.c (Fcall_interactively): <, not <=, for optimization.
19229 (Fcall_interactively): Count the number of arguments produced,
19230 not the number of arguments given. This is simpler and lets GCC
19231 4.6.0 generate slightly better code.
19233 * ftfont.c: Distingish more carefully between FcChar8 and char.
19234 The previous code passed unsigned char * to a functions like
19235 strlen and xstrcasecmp that expect char *, which does not
19236 conform to the C standard.
19237 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
19238 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
19239 char * when the C standard requires it.
19241 * keyboard.c (read_char): Remove unused var.
19243 * eval.c: Port to Windows vsnprintf (Bug#8435).
19244 Include <limits.h>.
19245 (SIZE_MAX): Define if the headers do not.
19246 (verror): Do not give up if vsnprintf returns a negative count.
19247 Instead, grow the buffer. This ports to Windows vsnprintf, which
19248 does not conform to C99. Problem reported by Eli Zaretskii.
19249 Also, simplify the allocation scheme, by avoiding the need for
19250 calling realloc, and removing the ALLOCATED variable.
19252 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
19254 Remove invocations of doprnt, as Emacs now uses vsnprintf.
19255 But keep the doprint source code for now, as we might revamp it
19256 and use it again (Bug#8435).
19257 * lisp.h (doprnt): Remove.
19258 * Makefile.in (base_obj): Remove doprnt.o.
19259 * deps.mk (doprnt.o): Remove.
19261 error: Print 32- and 64-bit integers portably (Bug#8435).
19262 Without this change, on typical 64-bit hosts error ("...%d...", N)
19263 was used to print both 32- and 64-bit integers N, which relied on
19264 undefined behavior.
19265 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
19266 * lisp.h (error, verror): Mark as printf-like functions.
19267 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
19268 Report overflow in size calculations when allocating printf buffer.
19269 Do not truncate output string at its first null byte.
19270 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
19271 Truncate the output at a character boundary, since vsnprintf does not
19273 * charset.c (check_iso_charset_parameter): Convert internal
19274 character to string before calling 'error', since %c now has the
19276 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
19277 overflow when computing char to be passed to 'error'. Do not
19278 pass Lisp_Object to 'error'; pass the integer instead.
19279 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
19280 formatted with plain %d.
19282 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
19284 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
19286 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
19288 * xterm.c (x_catch_errors): Remove duplicate declaration.
19290 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
19292 * xdisp.c, lisp.h (message_nolog): Remove; unused.
19294 2011-04-10 Jim Meyering <meyering@redhat.com>
19296 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
19297 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
19298 return ssize_t not "int", and use size_t as the buffer length.
19299 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
19300 * gnutls.h: Update declarations.
19301 * process.c (read_process_output): Use ssize_t, to match.
19302 (send_process): Likewise.
19304 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
19306 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
19308 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
19310 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
19311 Use unsigned char, to match FcChar8 type definition.
19313 * xterm.c (handle_one_xevent):
19314 * xmenu.c (create_and_show_popup_menu):
19315 * xselect.c (x_decline_selection_request)
19316 (x_reply_selection_request): Avoid type-punned deref of X events.
19318 2011-04-09 Eli Zaretskii <eliz@gnu.org>
19320 Fix some uses of `int' instead of EMACS_INT.
19321 * search.c (string_match_1, fast_string_match)
19322 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
19323 (scan_buffer, find_next_newline_no_quit)
19324 (find_before_next_newline, search_command, Freplace_match)
19325 (Fmatch_data): Make some `int' variables be EMACS_INT.
19327 * xdisp.c (display_count_lines): 3rd argument and return value now
19328 EMACS_INT. All callers changed.
19329 (pint2hrstr): Last argument is now EMACS_INT.
19331 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
19332 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)

19344 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
19345 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
19347 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
19348 (encode_invocation_designation): Last argument P_NCHARS is now
19350 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
19351 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
19353 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
19356 * ccl.c (Fccl_execute_on_string): Declare some variables
19359 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
19361 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
19363 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
19365 * process.c (Fformat_network_address): Doc fix.
19367 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
19369 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
19371 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
19373 * keyboard.c (read_char): Call Lisp function help-form-show,
19374 instead of using internal_with_output_to_temp_buffer.
19375 (Qhelp_form_show): New var.
19376 (syms_of_keyboard): Use DEFSYM macro.
19378 * print.c (internal_with_output_to_temp_buffer): Function deleted.
19380 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
19382 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
19384 * process.c (Flist_processes): Remove to Lisp.
19385 (list_processes_1): Delete.
19387 2011-04-06 Eli Zaretskii <eliz@gnu.org>
19389 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
19391 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
19393 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
19395 Fix more problems found by GCC 4.6.0's static checks.
19397 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
19399 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
19401 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
19403 * xdisp.c (vmessage): Mark as a printf-like function.
19405 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
19407 * sound.c (sound_warning): Don't crash if arg contains a printf format.
19409 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
19410 printf-like functions.
19411 (tiff_load): Add casts to remove these marks before passing them
19412 to system-supplied API.
19414 * eval.c (Fsignal): Remove excess argument to 'fatal'.
19416 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
19417 This avoids several warnings with gcc -Wstrict-overflow.
19418 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
19419 directly, rather than having caller test rule sign. This avoids
19420 some unnecessary tests.
19421 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
19422 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
19423 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
19425 * xfont.c (xfont_text_extents): Remove var that was set but not used.
19426 (xfont_open): Avoid unnecessary tests.
19428 * composite.c (composition_gstring_put_cache): Use unsigned integer.
19430 * composite.h, composite.c (composition_gstring_put_cache):
19431 Use EMACS_INT, not int, for length.

19434 breaking out part of COMPOSITION_DECODE_RULE.
19435 (COMPOSITION_DECODE_RULE): Use it.

19437 by using the new macro.
19439 * textprop.c (set_text_properties_1): Change while to do-while,
19440 since the condition is always true at first.
19442 * intervals.c (graft_intervals_into_buffer): Mark var as used.
19443 (interval_deletion_adjustment): Return unsigned value.
19446 * process.c (list_processes_1, create_pty, read_process_output):

19456 (update_syntax_table): Use unsigned instead of int.
19458 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
19459 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
19460 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
19462 * print.c (print_error_message): Avoid int overflow.
19464 * font.c (font_list_entities): Redo for clarity,
19465 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
19467 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
19468 (font_score): Avoid potential overflow in diff calculation.
19470 * fns.c (substring_both): Remove var that is set but not used.
19471 (sxhash): Redo loop for clarity and to avoid wraparound warning.
19473 * eval.c (funcall_lambda): Rename local to avoid shadowing.
19475 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
19476 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
19477 can always succeed if overflow has undefined behavior.
19479 * search.c (boyer_moore, wordify): Remove vars set but not used.
19480 (wordify): Omit three unnecessary tests.
19482 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
19483 All callers changed. This avoids the need for an unused var.
19485 * casefiddle.c (casify_region): Remove var that is set but not used.
19487 * dired.c (file_name_completion): Remove var that is set but not used.
19489 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
19491 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
19492 (Finsert_file_contents): Remove unnecessary code checking fd.
19494 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
19495 Check for integer overflow on size calculations.
19497 * buffer.c (Fprevious_overlay_change): Remove var that is set
19500 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
19501 Remove vars that are set but not used.
19502 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
19503 (timer_check_2): Mark vars as initialized.
19505 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
19507 * image.c (lookup_image): Remove var that is set but not used.
19508 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
19510 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
19511 that are set but not used.
19513 * xfns.c (make_invisible_cursor): Don't return garbage
19514 if XCreateBitmapFromData fails (Bug#8410).
19516 * xselect.c (x_get_local_selection, x_handle_property_notify):
19517 Remove vars that are set but not used.
19519 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
19520 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
19522 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
19523 Remove var that is set but not used.
19524 (scroll_bar_windows_size): Now size_t, not int.
19525 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
19526 Check for overflow.
19528 * xfaces.c (realize_named_face): Remove vars that are set but not used.
19529 (map_tty_color) [!defined MSDOS]: Likewise.
19531 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
19533 * coding.c: Remove vars that are set but not used.
19534 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
19535 All callers changed.
19536 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
19537 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
19538 (decode_coding_charset): Remove vars that are set but not used.
19540 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
19541 that is set but not used.
19543 * print.c (print_object): Remove var that is set but not used.
19545 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
19546 The gnulib version avoids calling malloc in the usual case,
19547 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
19548 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
19549 * filelock.c (current_lock_owner): Likewise.
19550 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
19551 * sysdep.c: Include allocator.h, careadlinkat.h.
19552 (emacs_no_realloc_allocator): New static constant.
19553 (emacs_readlink): New function.
19554 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
19555 ../lib/careadlinkat.h.
19557 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
19559 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the

19569 * xdisp.c (display_count_lines): Remove parameter `start',
19570 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.

19576 (get_per_char_metric): Remove parameter `f', unused since
19577 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
19579 2011-04-02 Jim Meyering <meyering@redhat.com>
19581 do not dereference NULL upon failed strdup
19582 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
19583 (ns_get_family): Likewise.
19585 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
19587 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
19589 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
19591 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
19594 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
19596 Add lexical binding.
19598 * window.c (Ftemp_output_buffer_show): New fun.
19599 (Fsave_window_excursion):
19600 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
19602 * lread.c (lisp_file_lexically_bound_p): New function.

19605 Bind Qinternal_interpreter_environment.
19606 (Feval_buffer): Bind Qlexical_binding.
19607 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
19609 (syms_of_lread): Declare `lexical-binding'.
19611 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
19613 * keyboard.c (eval_dyn): New fun.
19614 (menu_item_eval_property): Use it.
19616 * image.c (parse_image_spec): Use Ffunctionp.
19618 * fns.c (concat, mapcar1): Accept byte-code-functions.
19620 * eval.c (Fsetq): Handle lexical vars.
19621 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
19622 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
19623 (FletX, Flet): Obey lexical binding.
19624 (Fcommandp): Handle closures.
19625 (Feval): New `lexical' arg.
19626 (eval_sub): New function extracted from Feval. Use it almost
19627 everywhere where Feval was used. Look up vars in lexical env.
19629 (Ffunctionp): Move from subr.el.
19630 (Ffuncall): Handle closures.
19631 (apply_lambda): Remove `eval_flags'.
19632 (funcall_lambda): Handle closures and new byte-code-functions.
19633 (Fspecial_variable_p): New function.
19634 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
19635 but without exporting it to Lisp.
19637 * doc.c (Fdocumentation, store_function_docstring):
19638 * data.c (Finteractive_form): Handle closures.
19640 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
19643 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
19645 (exec_byte_code): New function extracted from Fbyte_code to handle new
19646 calling convention for byte-code-functions. Add new byte-codes.
19648 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
19650 * alloc.c (Fmake_symbol): Init new `declared_special' field.
19652 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
19654 * xdisp.c (redisplay_internal): Fix prototype.
19656 2011-03-31 Eli Zaretskii <eliz@gnu.org>
19658 * xdisp.c (SCROLL_LIMIT): New macro.
19659 (try_scrolling): Use it when setting scroll_limit.
19660 Limit scrolling to 100 screen lines.
19661 (redisplay_window): Even when falling back on "recentering",
19662 position point in the window according to scroll-conservatively,
19663 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
19665 (try_scrolling): When point is above the window, allow searching
19666 as far as scroll_max, or one screenful, to compute vertical
19667 distance from PT to the scroll margin position. This prevents
19668 try_scrolling from unnecessarily failing when
19669 scroll-conservatively is set to a value slightly larger than the
19670 window height. Clean up the case of PT below the margin at bottom
19671 of window: scroll_max can no longer be INT_MAX. When aggressive
19672 scrolling is in use, don't let point enter the opposite scroll
19673 margin as result of the scroll.
19674 (syms_of_xdisp) <scroll-conservatively>: Document the
19675 threshold of 100 lines for never-recentering scrolling.
19677 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
19679 * dispextern.h (move_it_by_lines):
19680 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused

19682 (message_log_check_duplicate): Remove parameters `prev_bol' and
19683 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
19684 (redisplay_internal): Remove parameter `preserve_echo_area',
19685 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
19687 * indent.c (Fvertical_motion):
19688 * window.c (window_scroll_pixel_based, Frecenter):
19689 Don't pass `need_y_p' to `move_it_by_lines'.
19691 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
19693 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
19694 steal a few bits to be more compact.
19695 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
19696 Remove unneeded casts.
19698 * bytecode.c (Fbyte_code): CAR and CDR can GC.
19700 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
19702 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
19703 binding" message (bug#7967).
19705 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
19707 Fix more problems found by GCC 4.6.0's static checks.
19709 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
19710 Remove unused local var.
19712 * editfns.c (Fmessage_box): Remove unused local var.
19714 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
19715 (note_mode_line_or_margin_highlight, note_mouse_highlight):
19716 Omit unused local vars.
19717 * window.c (shrink_windows): Omit unused local var.
19718 * menu.c (digest_single_submenu): Omit unused local var.
19719 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
19720 Omit unused local var.
19722 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
19723 Don't assume string length fits in int.
19724 (keyremap_step, read_key_sequence): Use size_t for sizes.

19727 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
19728 instead of alloca (Bug#8344).
19730 * eval.c (Fbacktrace): Don't assume nargs fits in int.
19731 (Fbacktrace_frame): Don't assume nframes fits in int.
19733 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.

19740 * cm.c (calccost): Turn while-do into do-while, for clarity.
19742 * keyboard.c (syms_of_keyboard): Use the same style as later
19743 in this function when indexing through an array. This also
19744 works around GCC bug 48267.
19746 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
19748 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
19750 * chartab.c (sub_char_table_ref_and_range): Redo for slight
19751 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
19753 * keyboard.c, keyboard.h (num_input_events): Now size_t.
19754 This avoids undefined behavior on integer overflow, and is a bit
19755 more convenient anyway since it is compared to a size_t variable.
19757 Variadic C functions now count arguments with size_t, not int.
19758 This avoids an unnecessary limitation on 64-bit machines, which
19759 caused (substring ...) to crash on large vectors (Bug#8344).

19769 * fns.c (concat): Likewise.
19770 * frame.c (x_set_frame_parameters): Likewise.
19771 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
19772 0 if not found, not -1. All callers changed.
19774 * alloc.c (garbage_collect): Don't assume stack size fits in int.
19775 (stack_copy_size): Now size_t, not int.
19776 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
19778 2011-03-28 Juanma Barranquero <lekktu@gmail.com>

19797 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
19798 don't set the hook to nil, but remove the offending function instead.
19799 (Qcommand_hook_internal): Remove, unused.
19800 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
19801 Vcommand_hook_internal.
19803 * eval.c (enum run_hooks_condition): Remove.
19804 (funcall_nil, funcall_not): New functions.
19805 (run_hook_with_args): Call each function through a `funcall' argument.

19985 unconditionally since it does the check itself.
19987 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
19989 Fix more problems found by GCC 4.5.2's static checks.
19991 * coding.c (encode_coding_raw_text): Avoid unnecessary test
19992 the first time through the loop, since we know p0 < p1 then.
19993 This also avoids a gcc -Wstrict-overflow warning.
19995 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
19996 leading to a memory leak, possible in functions like
19997 load_charset_map_from_file that can allocate an unbounded number
19998 of objects (Bug#8318).
20000 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
20001 that could (at least in theory) be that large.
20003 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
20004 This is less likely to overflow, and avoids undefined behavior if
20005 overflow does occur. All callers changed. Use strtoul to scan
20006 for the unsigned long integer.
20007 (pint2hrstr): Simplify and tune code slightly.
20008 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
20010 * scroll.c (do_scrolling): Work around GCC bug 48228.
20011 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.

20016 This also avoids a warning with gcc -Wstrict-overflow.
20018 * fileio.c (Fcopy_file): Report error if fchown or fchmod
20021 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
20023 * process.c (Fmake_network_process): Use socklen_t, not int,
20024 where POSIX says socklen_t is required in portable programs.
20025 This fixes a porting bug on hosts like 64-bit HP-UX, where
20026 socklen_t is wider than int (Bug#8277).
20027 (Fmake_network_process, server_accept_connection):
20028 (wait_reading_process_output, read_process_output):
20031 * process.c: Rename or move locals to avoid shadowing.

20043 Include tparam.h instead, since it declares them.
20044 * cm.h (PC): Remove extern decl; tparam.h now does this.
20045 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
20046 * terminfo.c: Include tparam.h, to check interfaces.
20047 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
20048 (tparam): Adjust signature to match interface in tparam.h;
20049 this removes some undefined behavior. Check that outstring and len
20050 are zero, which they always are with Emacs.
20051 * tparam.h (PC, BC, UP): New extern decls.
20053 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
20054 (xftfont_open): Rename locals to avoid shadowing.

20078 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
20079 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
20080 (BUF_DEC_POS): Be more systematic about renaming local temporaries
20081 to avoid shadowing.
20083 * textprop.c (property_change_between_p): Remove; unused.
20085 * intervals.c (interval_start_pos): Now static.
20087 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

20093 Fix pointer signedness.
20094 (alsa_choose_format): Remove unused local var.
20095 (wav_play): Initialize a variable to 0, to prevent undefined
20096 behavior (Bug#8278).
20098 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
20100 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
20102 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
20103 clobbering (Bug#8298).
20104 * sysdep.c (sys_subshell): Likewise.
20105 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
20107 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
20108 This should get cleaned up, so that child_setup has the
20109 same signature on all platforms.
20111 * callproc.c (call_process_cleanup): Now static.
20112 (relocate_fd): Rename locals to avoid shadowing.
20114 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
20116 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
20117 not to be necessary, and produces flickering.
20119 2011-03-20 Glenn Morris <rgm@gnu.org>
20121 * config.in: Remove file.
20123 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
20125 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
20126 are now in src/globals.h.
20127 (syms_of_minibuf): Remove spurious & from previous change.

20137 * xfaces.c (Fx_load_color_file):
20138 Read color file from absolute filename (bug#8250).
20140 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
20142 * makefile.w32-in: Update dependencies.
20144 2011-03-17 Eli Zaretskii <eliz@gnu.org>

20153 (sigchld_handler): Now static.
20155 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
20156 That way, the code declares only the vars that it needs.

20167 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
20168 Define only if needed.
20170 * unexelf.c (unexec): Name an expression,
20171 to avoid gcc -Wbad-function-cast warning.
20172 Use a different way to cause a compilation error if anyone uses
20173 n rather than nn, a way that does not involve shadowing.
20174 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
20176 * deps.mk (unexalpha.o): Remove; unused.
20178 New file unexec.h, the (simple) interface for unexec (Bug#8267).
20179 * unexec.h: New file.
20180 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
20181 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
20182 Depend on unexec.h.
20183 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
20184 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
20185 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.
20186 Change as necessary to match prototype in unexec.h.
20188 * syntax.c (Fforward_comment, scan_lists): Rename locals to avoid

20242 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
20243 some of which prompt warnings from gcc -Wbad-function-cast.
20244 (Fformat_time_string, Fencode_time, Finsert_char):
20245 (Ftranslate_region_internal, Fformat):
20246 Rename or remove local vars to avoid shadowing.

20249 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
20252 * lisp.h (eassert): Check that the argument compiles, even if
20253 ENABLE_CHECKING is not defined.
20255 * data.c (Findirect_variable): Name an expression, to avoid
20256 gcc -Wbad-function-cast warning.

20268 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
20269 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
20271 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
20272 (GC_STRING_CHARS): Remove; not used.
20273 (Fmemory_limit): Cast sbrk's returned value to char *.
20275 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
20276 avoids undefined behavior in theory.
20278 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
20280 Use functions, not macros, for up- and down-casing (Bug#8254).
20281 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
20282 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
20283 to use the following functions instead of these macros.
20284 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
20285 EMACS_INT, since callers assume the returned value fits in int.
20286 (upcase1): Likewise, for UPCASE_TABLE.
20287 (uppercasep, lowercasep, upcase): New static inline functions.
20288 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

20297 which gcc can warn about.
20298 (regex_compile, re_match_2_internal): Mark locals as initialized.
20299 (RETALLOC_IF): Define only if needed.
20300 (WORDCHAR_P): Likewise. This one is never needed, but is used
20301 only in a comment talking about a compiler bug, so put inside
20302 the #if 0 of that comment.
20303 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
20304 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
20307 * search.c (boyer_moore): Rename locals to avoid shadowing.

20330 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
20331 New macros, so that the caller can use some names other than
20332 gcpro1, gcpro2, etc.
20333 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
20335 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
20336 argument, for consistency with GCPRO2_VAR, etc: it is now the
20337 prefix of the variable, not the variable itself. All uses
20339 * dired.c (directory_files_internal, file_name_completion):
20340 Rename locals to avoid shadowing.
20342 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
20343 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
20344 dired.c's scmp function, had undefined behavior.
20345 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
20346 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
20347 * buffer.h: ... to here, because these macros use current_buffer,
20348 and the new implementation with inline functions needs to have
20349 current_buffer in scope now, rather than later when the macros
20351 (downcase, upcase1): New static inline functions.
20352 (DOWNCASE, UPCASE1): Reimplement using these functions.
20353 This avoids undefined behavior in expressions like
20354 DOWNCASE (x) == DOWNCASE (y), which previously suffered
20355 from race conditions in accessing the global variables
20356 case_temp1 and case_temp2.
20357 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
20358 * lisp.h (case_temp1, case_temp2): Remove their decls.
20359 * character.h (ASCII_CHAR_P): Move from here ...
20360 * lisp.h: ... to here, so that the inline functions mentioned
20361 above can use them.
20363 * dired.c (directory_files_internal_unwind): Now static.
20365 * fileio.c (file_name_as_directory, directory_file_name):

20368 (file_name_as_directory): Use const pointers when appropriate.
20369 (Fexpand_file_name): Likewise. In particular, newdir might
20370 point at constant storage, so make it a const pointer.
20371 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
20372 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
20374 (Fset_file_times, Finsert_file_contents, auto_save_error):
20375 Rename locals to avoid shadowing.
20377 * minibuf.c (choose_minibuf_frame_1): Now static.
20378 (Ftry_completion, Fall_completions): Rename or remove locals
20379 to avoid shadowing.
20381 * marker.c (bytepos_to_charpos): Remove; unused.
20383 * lisp.h (verify_bytepos, count_markers): New decls,
20384 so that gcc does not warn that these functions aren't declared.
20386 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
20387 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
20388 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
20389 (copy_text): Remove unused local var.
20391 * filelock.c (within_one_second): Now static.
20392 (lock_file_1): Rename local to avoid shadowing.
20394 * buffer.c (fix_overlays_before): Mark locals as initialized.
20395 (fix_start_end_in_overlays): Likewise. This function should be
20396 simplified by using pointers-to-pointers, but that's a different
20398 (switch_to_buffer_1): Now static.
20399 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
20400 (report_overlay_modification): Rename locals to avoid shadowing.
20402 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
20403 Fix pointer signedness issue.
20404 (sys_subshell): Mark local as volatile if checking for lint,
20405 to suppress a gcc -Wclobbered warning that does not seem to be right.
20406 (MAXPATHLEN): Define only if needed.
20408 * process.c (serial_open, serial_configure): Move decls from here ...
20409 * systty.h: ... to here, so that they can be checked.
20411 * fns.c (get_random, seed_random): Move extern decls from here ...
20412 * lisp.h: ... to here, so that they can be checked.
20414 * sysdep.c (reset_io): Now static.
20415 (wait_for_termination_signal): Remove; unused.
20417 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
20418 (copy_keymap_item, append_key, push_text_char_description):
20420 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
20421 (DENSE_TABLE_SIZE): Remove; unused.
20422 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
20423 (describe_map_tree):
20424 Rename locals to avoid shadowing.
20426 * keyboard.c: Declare functions static if they are not used elsewhere.
20427 (echo_char, echo_dash, cmd_error, top_level_2):
20428 (poll_for_input, handle_async_input): Now static.
20429 (read_char, kbd_buffer_get_event, make_lispy_position):
20430 (make_lispy_event, make_lispy_movement, apply_modifiers):
20431 (decode_keyboard_code, tty_read_avail_input, menu_bar_items):
20432 (parse_tool_bar_item, read_key_sequence, Fread_key_sequence):
20433 (Fread_key_sequence_vector): Rename locals to avoid shadowing.
20434 (read_key_sequence, read_char): Mark locals as initialized.

20441 * lisp.h (force_auto_save_soon): New decl.
20443 * emacs.c (init_cmdargs): Rename local to avoid shadowing.
20444 (DEFINE_DUMMY_FUNCTION): New macro.
20445 (__do_global_ctors, __do_global_ctors_aux, __do_global_dtors, __main):
20447 (main): Add casts to avoid warnings
20448 if GCC considers string literals to be constants.
