220 * w32.c (unsetenv): Return 0 if the input string is too long.
222 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>

239 no longer needed here.
240 (set_time_zone_rule_tz1, set_time_zone_rule_tz2) [LOCALTIME_CACHE]:
241 Move to inside set_time_zone_rule; they don't need file scope any more.
242 (set_time_zone_rule): Maintain the TZ=value string separately.
243 (syms_of_editfns): Don't initialize initial_tz;
244 init_editfns now does it.
245 * emacs.c (dump_tz) [HAVE_TZSET]: Now const.
246 * lisp.h (xputenv): New decl.
248 2012-12-08 Fabrice Popineau <fabrice.popineau@gmail.com>

264 * vm-limit.c (get_lim_data): Combine RLIMIT_AS and RLIMIT_DATA methods.
265 Remove USG and vlimit methods; no longer used these days.
266 Add #error catchall just in case.
268 Assume POSIX 1003.1-1988 or later for signal.h (Bug#13026).
269 Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,
270 SIGTTOU, SIGUSR1, SIGUSR2, as Microsoft platforms lack these.
271 * process.c [subprocesses]: Include <c-ctype.h>, <sig2str.h>.
272 (deleted_pid_list, Fdelete_process, create_process)
273 (record_child_status_change, handle_child_signal, deliver_child_signal)

281 (emacs_sigaction_init): Assume SIGCHLD is defined.
282 (init_signals): Assume SIGALRM, SIGCHLD, SIGHUP, SIGKILL,

292 This will cause a production Emacs to dump core instead of
295 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
297 * frame.c (make_frame): Do not set window's buffer to t.
298 * window.c (Fsplit_window_internal): Likewise. Previously it was
299 used to indicate that the window is being set up. Now we use
300 set_window_buffer for all new windows, so the condition in ...
301 (Fset_window_buffer): ... is always true and can be removed.
303 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
305 Convenient macro to check whether the buffer is hidden.
306 * buffer.h (BUFFER_HIDDEN_P): New macro.

313 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG
314 if the child process is still running. Instead, exit the wait
315 loop and return zero. (Bug#13086)
317 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
319 * frame.h (x_char_width, x_char_height): Remove prototypes.

332 Fix a recently-introduced delete-process race condition.
333 * callproc.c, process.h (record_kill_process):
334 New function, containing part of the old call_process_kill.
335 (call_process_kill): Use it.
336 This does not change call_process_kill's behavior.
337 * process.c (Fdelete_process): Use record_kill_process to fix a
338 race condition that could cause Emacs to lose track of a child.
340 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
342 Avoid code duplication between prev_frame and next_frame.
343 * frame.c (candidate_frame): New function. Add comment.
344 (prev_frame, next_frame): Use it. Adjust comment.
346 2012-12-06 Eli Zaretskii <eliz@gnu.org>
348 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
349 fails, signal an error instead of continuing with an empty
351 Encode expanded temp file pattern before passing it to mkstemp or
354 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
355 Encode the file name before passing it to dostounix_filename, in
356 case it will downcase it (under w32-downcase-file-names).
359 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
361 Minor call-process cleanups.
362 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
363 at the same time as other platforms, to simplify analysis.
364 No need for fd0_volatile since we have synch_process_fd.
365 Avoid needless emacs_close; arg is always negative.
367 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
369 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
372 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
374 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
375 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
376 and mouse_face_hidden members to a bitfields.
377 * frame.h (struct frame): Remove set-but-not-used space_width member.
378 (FRAME_SPACE_WIDTH): Remove.
379 * nsterm.m, w32term.c, xterm.c: Adjust users.

381 member. Adjust users. Convert term_initted, delete_in_insert_mode,
382 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
383 members to a bitfields.
385 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
387 Don't let call-process be a zombie factory (Bug#12980).
388 Fixing this bug required some cleanup of the signal-handling code.
389 As a side effect, this change also fixes a longstanding rare race
390 condition whereby Emacs could mistakenly kill unrelated processes,
391 and it fixes a bug where a second C-g does not kill a recalcitrant
392 synchronous process in GNU/Linux and similar platforms.
393 The patch should also fix the last vestiges of Bug#9488,
394 a bug which has mostly been fixed on the trunk by other changes.
395 * callproc.c, process.h (synch_process_alive, synch_process_death)
396 (synch_process_termsig, sync_process_retcode):
397 Remove. All uses removed, to simplify analysis and so that
398 less consing is done inside critical sections.
399 * callproc.c (call_process_exited): Remove. All uses replaced
400 with !synch_process_pid.
401 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
402 These take the role of what used to be in unwind-protect arg.
404 (block_child_signal, unblock_child_signal):
405 New functions, to avoid races that could kill innocent-victim processes.
406 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
407 (call_process_kill): Record killed processes as deleted, so that
408 zombies do not clutter up the system. Do this inside a critical
409 section, to avoid a race that would allow the clutter.
410 (call_process_cleanup): Fix code so that the second C-g works again
411 on common platforms such as GNU/Linux.
412 (Fcall_process): Create the child process in a critical section,
413 to fix a race condition. If creating an asynchronous process,
414 record it as deleted so that zombies do not clutter up the system.
415 Do unwind-protect for WINDOWSNT too, as that's simpler in the
416 light of these changes. Omit unnecessary call to emacs_close
417 before failure, as the unwind-protect code does that.
418 * callproc.c (call_process_cleanup):
419 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
420 * process.c (record_deleted_pid): New function, containing
421 code refactored out of Fdelete_process.
422 (Fdelete_process): Use it.
423 (process_status_retrieved): Remove. All callers changed to use
425 (record_child_status_change): Remove, folding its contents into ...
426 (handle_child_signal): ... this signal handler. Now, this
427 function is purely a handler for SIGCHLD, and is not called after
428 a synchronous waitpid returns; the synchronous code is moved to
429 wait_for_termination. There is no need to worry about reaping
430 more than one child now.
431 * sysdep.c (get_child_status, child_status_changed): New functions.
432 (wait_for_termination): Now takes int * status and bool
433 interruptible arguments, too. Do not record child status change;
434 that's now the caller's responsibility. All callers changed.
435 Reimplement in terms of get_child_status.
436 (wait_for_termination_1, interruptible_wait_for_termination):
437 Remove. All callers changed to use wait_for_termination.
438 * syswait.h: Include <stdbool.h>, for bool.
439 (record_child_status_change, interruptible_wait_for_termination):
441 (record_deleted_pid, child_status_changed): New decls.
442 (wait_for_termination): Adjust to API changes noted above.
444 * bytecode.c, lisp.h (Qbytecode): Remove.
445 No longer needed after 2012-11-20 interactive-p changes.
447 2012-12-03 Eli Zaretskii <eliz@gnu.org>
449 * xdisp.c (redisplay_window): If the cursor is visible, but inside
450 the scroll margin, move point outside the margin. (Bug#13055)
452 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
454 * gtkutil.c (my_log_handler): New function.
455 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).

459 * lisp.h (modify_region): Rename to...
460 (modify_region_1): ...new prototype.
461 * textprop.c (modify_region): Now static. Adjust users.
462 * insdel.c (modify_region): Rename to...
463 (modify_region_1): ...new function to work with current buffer.
464 Adjust comment and users. Use true and false for booleans.
466 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
468 * alloc.c (free_save_value): New function.
469 (safe_alloca_unwind): Use it.
470 * lisp.h (free_save_value): New prototype.
471 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
473 (save_excursion_restore): Adjust to match saved data structure.
474 Use free_save_value to offload some work from GC. Drop obsolete
477 2012-12-03 Chong Yidong <cyd@gnu.org>
479 * fileio.c (Vauto_save_list_file_name): Doc fix.
481 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>

501 Fix xpalloc confusion after memory is exhausted.
502 * alloc.c (xpalloc): Comment fix.
503 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
504 and signals an error, do not clear charset_table_size, as
505 charset_table is still valid.
506 * doprnt.c (evxprintf): Clear *BUF after freeing it.
508 Use execve to avoid need to munge environ (Bug#13054).
509 * callproc.c (Fcall_process):
510 * process.c (create_process):
511 Don't save and restore environ; no longer needed.
512 * callproc.c (child_setup):
513 Use execve, not execvp, to preserve environ.
515 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
517 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
519 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
521 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
522 display for sliced images (Bug#10500).
524 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
526 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
528 * doc.c (Fdocumentation): Re-add handling of function-documentation,
529 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
531 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
533 * xdisp.c (window_outdated): Remove eassert since it hits
534 some suspicious corner cases (see Bug#13007 and Bug#13012).
535 (mode_line_update_needed): New function.
536 (redisplay_internal, redisplay_window): Use it.
537 (ensure_selected_frame): New function.
538 (redisplay_internal, unwind_redisplay): Use it.
539 (redisplay_internal): Move comment about buffer_shared...
540 (buffer_shared_and_changed): ...near to its real use.
542 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
544 * callproc.c (Fcall_process): Don't misreport vfork failure.
546 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
548 * callproc.c (Fcall_process): Fix vfork portability problems.
549 Do not assume that fd[0], count, filefd, and save_environ survive
550 vfork. Fix bug whereby wrong errno value could be reported for
551 pipe failure. Some minor cleanups, too, as follows. Move buf and
552 bufsize to the context where they're needed. Change new_argv to
553 be of type char **, as this is more convenient and avoids casts.
554 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
555 Now local constants, not macros.
557 2012-11-18 Kenichi Handa <handa@gnu.org>
559 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
560 for the variable "f".
562 2012-11-13 Kenichi Handa <handa@gnu.org>
564 * font.c (font_unparse_xlfd): Exclude special characters from the
565 generating XLFD name.
567 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>
569 Assume POSIX 1003.1-1988 or later for grp.h, pwd.h.
570 * dired.c (stat_uname, stat_gname):
571 * fileio.c (Fexpand_file_name): Remove no-longer-needed casts.
573 Assume POSIX 1003.1-1988 or later for errno.h (Bug#12968).
574 * dired.c (directory_files_internal, file_name_completion):
575 Assume EAGAIN and EINTR are defined.
577 * fileio.c (Fcopy_file): Assume EISDIR is defined.
578 * gmalloc.c (ENOMEM, EINVAL): Assume they're defined.
579 * gnutls.c (emacs_gnutls_write): Assume EAGAIN is defined.
580 * lread.c (readbyte_from_file): Assume EINTR is defined.
581 * process.c (wait_reading_process_output, send_process) [subprocesses]:
582 Assume EIO and EAGAIN are defined.
583 * unexcoff.c (write_segment): Assume EFAULT is defined.
585 2012-11-27 Eli Zaretskii <eliz@gnu.org>
587 * fontset.c (Finternal_char_font): Return nil on non-GUI frames.
590 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
591 highlighting on the frame was cleared. Prevents assertion
592 violations when repeatedly clicking on the "Top" link of the
593 "bread-crumbs" in Info buffers.
595 2012-11-25 Paul Eggert <eggert@cs.ucla.edu>

602 * frame.c (HAVE_MOUSE): Remove, and rewrite code as if HAVE_MOUSE
605 2012-11-24 Eli Zaretskii <eliz@gnu.org>
607 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
608 between bpos_covered and bpos_max. This fixes cursor display when
609 several display strings follow each other.
611 * .gdbinit (pgx): If the glyph's object is a string, display the
612 pointer to string data, rather than the value of the string object
613 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
615 * indent.c (Fvertical_motion): If the starting position is covered
616 by a display string, return to one position before that, to avoid
617 overshooting it inside move_it_to. (Bug#12930)
619 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
621 * frame.h (struct frame): Remove display_preempted member
622 since all users are dead long ago.
623 * nsterm.h (struct x_output): Use the only dummy member.
624 * w32menu.c (pending_menu_activation): Remove since not
626 (set_frame_menubar): Adjust user.
627 * w32term.h (struct x_output): Drop outdated #if 0 code.
628 (struct w32_output): Use bitfields for explicit_parent,
629 asked_for_visible and menubar_active members. Drop
630 unused pending_menu_activation member.
631 * xterm.h (struct x_output): Drop outdated #if 0 code.
632 Use bitfields for explicit_parent, asked_for_visible,
633 has_been_visible and net_wm_state_hidden_seen members.
635 2012-11-23 Eli Zaretskii <eliz@gnu.org>
637 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
638 of a literal "/". (Bug#12955)
639 (gl-stamp): Invoke fc.exe directly, not through cmd.
641 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>
643 Assume POSIX 1003.1-1988 or later for dirent.h (Bug#12958).
644 * dired.c: Assume HAVE_DIRENT_H.
645 (NAMLEN): Remove, replacing with ...
646 (dirent_namelen): New function. All uses changed. Use the GNU macro
647 _D_EXACT_NAMELEN if available, as it's faster than strlen.
648 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
649 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
650 * makefile.w32-in (DIR_H): Remove. All uses replaced with
652 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
653 * ndir.h: Rename to ../nt/inc/dirent.h.
654 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
655 Do not include <dirent.h>; no longer needed.
656 * w32.c: Include <dirent.h> rather than "ndir.h".
658 2012-11-23 Chong Yidong <cyd@gnu.org>
660 * xftfont.c (xftfont_open): Remove duplicate assignment.
662 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
664 * alloc.c (Fgarbage_collect): Unblock input after clearing
665 gc_in_progress to avoid note_mouse_highlight glitch with GC.
666 * frame.h (FRAME_MOUSE_UPDATE): New macro.
667 * msdos.c (IT_frame_up_to_date): Use it here...
668 * w32term.c (w32_frame_up_to_date): ...here...
669 * xterm.c (XTframe_up_to_date): ...and here...
670 * nsterm.m (ns_frame_up_to_date): ...but not here.
671 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
673 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
674 Do not check whether GC is in progress.

678 * xdisp.c (window_buffer_changed): New function.
679 (update_menu_bar, update_tool_bar): Use it to
680 simplify large 'if' statements.
681 (redisplay_internal): Generalize commonly used
682 'tail' and 'frame' local variables.
684 2012-11-22 Eli Zaretskii <eliz@gnu.org>
686 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
687 with Windows system header.
689 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
691 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
692 * alloc.c: Assume unistd.h exists.
693 * fileio.c (Fexpand_file_name) [DOS_NT]: Use getcwd, not getwd.
694 * sysdep.c (get_current_dir_name): Assume getcwd exists.
695 (getwd) [USG]: Remove; no longer needed.
696 (sys_subshell) [DOS_NT]: Use getcwd, not getwd.
697 * w32.c (getcwd): Rename from getwd, and switch to getcwd's API.
698 * w32.h (getcwd): Remove decl.
700 2012-11-21 Stefan Monnier <monnier@iro.umontreal.ca>
702 * xdisp.c (fast_set_selected_frame): Rename from update_tool_bar_unwind.
703 Make it set selected_window as well.
704 (update_tool_bar): Use it.
706 2012-11-21 Ken Brown <kbrown@cornell.edu>
708 * emacs.c (main): Set the G_SLICE environment variable for all
709 Cygwin builds, not just GTK builds. See
710 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
712 2012-11-21 Eli Zaretskii <eliz@gnu.org>
714 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
715 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
716 Define for the MSVC compiler.
718 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
720 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
721 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
722 dostounix_filename. Prevents crashes down the road, because
723 dostounix_filename assumes it gets a unibyte string. Reported by
724 Michel de Ruiter <michel@sentient.nl>, see
725 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html
727 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
729 Conflate Qnil and Qunbound for `symbol-function'.
730 * alloc.c (Fmake_symbol): Initialize `function' to Qnil.
731 * lread.c (init_obarray): Set `function' fields to Qnil.
732 * eval.c (Fcommandp): Ignore Qunbound.
733 (Fautoload, eval_sub, Fapply, Ffuncall, Fmacroexpand):
734 * data.c (Ffset, Ffboundp, indirect_function, Findirect_function):
735 Test NILP rather than Qunbound.
736 (Ffmakunbound): Set to Qnil.
737 (Fsymbol_function): Never signal an error.
738 (Finteractive_form): Ignore Qunbound.
740 2012-11-20 Paul Eggert <eggert@cs.ucla.edu>
742 * eval.c (interactive_p): Remove no-longer-used decl.
744 2012-11-20 Dmitry Antipov <dmantipov@yandex.ru>
746 * xdisp.c (buffer_shared): Adjust comment.
747 (buffer_shared_and_changed): New function.
748 (prepare_menu_bars, redisplay_internal): Use it to
749 decide whether all windows or frames should be updated.
750 (window_outdated): New function.
751 (text_outside_line_unchanged_p, redisplay_window): Use it.
752 (redisplay_internal): Likewise. Fix indentation.
754 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
756 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
757 (syms_of_eval): Remove corresponding defsubr.
758 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
760 2012-11-19 Daniel Colascione <dancol@dancol.org>
762 * w32fns.c (Fx_file_dialog):
763 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
764 cygwin_convert_file_name*.
766 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
767 Rename cygwin_convert_path* to cygwin_convert_file_name*.
769 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
771 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
773 2012-11-18 Eli Zaretskii <eliz@gnu.org>
775 * w32select.c: Include w32common.h before w32term.h, so that
776 windows.h gets included before w32term.h uses some of its
779 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
781 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
783 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
785 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
787 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
788 (ns_select): Return at once if events are held (Bug#12834).
790 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
792 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
793 Needed following 2012-10-20 change. (Bug#12902)
795 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
797 * w32proc.c (waitpid): Remove unused label get_result.
799 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
801 * makefile.w32-in (SYSWAIT_H): New macro.
802 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
803 ($(BLD)/sysdep.$(O)): Update dependencies.
805 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
807 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
808 * callproc.c (relocate_fd): Assume F_DUPFD.
809 * emacs.c, term.c (O_RDWR): Remove.
810 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
811 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
812 * nsterm.m: Assume <fcntl.h> exists.
813 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
814 (create_pty, Fmake_network_process, server_accept_connection)
815 (wait_reading_process_output, init_process_emacs):
817 (wait_reading_process_output): Put in a special case for WINDOWSNT
818 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
819 It's not clear this is needed, but it's a more-conservative change.
820 (create_process): Assume FD_CLOEXEC.
821 (create_process, create_pty): Assume O_NOCTTY.
822 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
823 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
824 Omit if not DOS_NT, since F_GETFL is not defined there.
825 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
826 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
828 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
829 lack it, since gnulib guarantees this.
830 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
832 2012-11-17 Eli Zaretskii <eliz@gnu.org>
834 * w32.c (faccessat): Pretend that directories have the execute bit
835 set. Emacs expects that, e.g., in files.el:cd-absolute.
837 * w32proc.c (create_child): Don't clip the PID of the child
838 process to fit into an Emacs integer, as this is no longer a
840 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
841 reaping only the process specified by PID argument, if that is
842 positive. Use PID instead of dead_child to know which process to
843 reap. Wait for the child to die only if WNOHANG is not in
845 (sys_select): Don't set dead_child.
847 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
848 as it is no longer needed.
850 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
852 (record_child_status_change): Remove the setting of
853 record_at_most_one_child for the !WNOHANG case.
855 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
857 Fix problems in ns port found by static checking.
858 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
859 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
860 not to process group.
861 (ns_select): Use emacs_write, not write, as that's more robust
862 in the presence of signals.
863 (fd_handler:): Check for read errors.
865 2012-11-16 Glenn Morris <rgm@gnu.org>
867 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
869 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
871 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
873 2012-11-16 Eli Zaretskii <eliz@gnu.org>
875 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
876 use the same value of thread handle.
877 (start_timer_thread): If the timer thread exited (due to error),
878 clean up by closing the two handles it used. Duplicate the caller
879 thread's handle here, so it gets duplicated only once, when
880 launching the timer thread. Set priority of the timer thread, not
882 (getitimer): Don't duplicate the caller thread's handle here.
885 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
887 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
890 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
892 Remove no-longer-used pty_max_bytes variable.
893 * process.c (pty_max_bytes): Remove; unused.
894 (send_process): Do not set it.
896 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
898 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
901 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
903 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
904 This follows up on the 2012-09-29 patch that removed indirection
905 for the 'function' field. Reported by Sergey Vinokurov in
906 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
908 2012-11-14 Eli Zaretskii <eliz@gnu.org>
910 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
911 different name, as the MS runtime does not have such a function,
912 and probably never will.) All callers changed. Ignore DIRFD
913 value if PATH is an absolute file name, to match Posix spec
914 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
917 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
919 * xdisp.c (echo_area_display, redisplay_internal):
920 Omit redundant check whether frame_garbaged is set.
922 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
924 Use faccessat, not access, when checking file permissions (Bug#12632).
925 This fixes a bug that has been present in Emacs since its creation.
926 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
927 which must set some sort of record. (Torek's bug report was against
928 a predecessor of GNU Emacs, but GNU Emacs happened to have the
929 same common flaw.) See Torek's Usenet posting
930 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
931 Posted: Fri Apr 8 14:18:56 1983.
932 * Makefile.in (LIB_EACCESS): New macro.
934 * callproc.c (init_callproc):
935 * charset.c (init_charset):
936 * fileio.c (check_existing, check_executable, check_writable)
938 * lread.c (openp, load_path_check):
939 * process.c (allocate_pty):
941 Use effective UID when checking permissions, not real UID.
942 * callproc.c (init_callproc):
943 * charset.c (init_charset):
944 * lread.c (load_path_check, init_lread):
945 Test whether directories are accessible, not merely whether they exist.
946 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
947 * fileio.c (check_existing, check_executable, check_writable)
949 Use symbolic names instead of integers for the flags, as they're
951 (check_writable): New arg AMODE. All uses changed.
952 Set errno on failure.
953 (Ffile_readable_p): Use faccessat, not stat + open + close.
954 (Ffile_writable_p): No need to call check_existing + check_writable.
955 Just call check_writable and then look at errno. This saves a syscall.
956 dir should never be nil; replace an unnecessary runtime check
957 with an eassert. When checking the parent directory of a nonexistent
958 file, check that the directory is searchable as well as writable, as
959 we can't create files in unsearchable directories.
960 (file_directory_p): New function, which uses 'stat' on most platforms
961 but faccessat with D_OK (for efficiency) if WINDOWSNT.
962 (Ffile_directory_p, Fset_file_times): Use it.
963 (file_accessible_directory_p): New function, which uses a single
964 syscall for efficiency.
965 (Ffile_accessible_directory_p): Use it.
966 * xrdb.c (file_p): Use file_directory_p.
967 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
968 * lread.c (openp): When opening a file, use fstat rather than
969 stat, as that avoids a permissions race. When not opening a file,
970 use file_directory_p rather than stat.
971 (dir_warning): First arg is now a usage string, not a format.
972 Use errno. All uses changed.
973 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
974 that merely introduced a race.
975 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
976 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
977 and similarly for the other O_* flags.
978 * w32.c (sys_faccessat): Rename from sys_access and switch to
979 faccessat's API. All uses changed.
980 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
981 (magic_db): Rename from magic_file_p.
982 (magic_db, search_magic_path): Return an XrmDatabase rather than a
983 char *, so that we don't have to test for file existence
984 separately from opening the file for reading. This removes a race
985 fixes a permission-checking problem, and simplifies the code.
987 (file_p): Remove; no longer needed.
989 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
991 Omit glyphs initialization at startup.

1002 passed to pint2str and pint2hrstr to be at most the size of the
1003 frame's decode_mode_spec_buffer. This avoids crashes with very
1004 large values of FIELD_WIDTH argument to decode_mode_spec.
1007 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
1009 Fix a race with verify-visited-file-modtime (Bug#12863).
1010 Since at least 1991 Emacs has ignored an mtime difference of no
1011 more than one second, but my guess is that this was to work around
1012 file system bugs that were fixed long ago. Since the race is
1013 causing problems now, let's remove that code.
1014 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
1015 whose time stamp is off by no more than a second. Insist that the
1016 file time stamps match exactly.

1037 * xselect.c (frame_for_x_selection): Likewise.
1038 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
1039 (x_window_to_menu_bar): Likewise.
1040 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
1042 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
1044 * data.c (Qdefalias_fset_function): Now static.
1046 Another tweak to vectorlike_header change.
1047 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
1048 Remove, and replace all uses with ...
1049 (next_in_free_list, set_next_in_free_list):
1050 New functions, which respect C's aliasing rules better.
1052 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
1054 * window.c (list4i): Rename from 'quad'. All uses changed.
1055 Needed because <sys/types.h> defines 'quad' on Solaris 10.
1057 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
1059 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
1060 warning about mixing declarations and code in ISO C90.
1062 2012-11-10 Martin Rudalics <rudalics@gmx.at>
1064 * window.c (Fsplit_window_internal): Set combination limit of
1065 new parent window to t iff Vwindow_combination_limit is t;
1066 fixing a regression introduced with the change from 2012-09-22.
1067 (Fset_window_combination_limit): Fix doc-string.
1069 2012-11-10 Eli Zaretskii <eliz@gnu.org>
1071 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
1072 amount when the scroll margins are too large. When scrolling
1073 backwards in the buffer, give up if cannot reach point or the
1074 scroll margin within a reasonable number of screen lines.
1075 Fixes point position in window under scroll-up/down-aggressively when
1076 point is positioned many lines beyond the window top/bottom.
1079 * ralloc.c (relinquish): If real_morecore fails to return memory
1080 to the system, don't crash; instead, leave the last heap
1081 unchanged and return. (Bug#12774)

1090 (Finteractive_form): Simplify.
1091 (Fquo): Don't insist on having at least 2 arguments.
1092 (Qdefalias_fset_function): New var.
1094 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
1096 * image.c (xpm_make_color_table_h): Change to hashtest_equal.

1102 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
1104 Fix recently introduced crash on MS-Windows (Bug#12839).
1105 * w32term.h (struct scroll_bar): Use convenient header.
1106 (SCROLL_BAR_VEC_SIZE): Remove.
1107 * w32term.c (x_scroll_bar_create): Use VECSIZE.
1109 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
1111 Tweak last vectorlike_header change.
1112 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
1113 vectorlike object on the free list. This is introduced to avoid
1114 some (but not all) pointer casting and aliasing problems, see
1115 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
1116 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike

1120 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
1122 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
1123 been removed, so remove them here also.
1125 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
1127 * doc.c (Fdocumentation): Handle new property
1128 dynamic-docstring-function to replace the old ad-advice-info.
1130 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
1132 * fns.c (Qeql, hashtest_eq): Now static.
1134 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
1136 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
1137 * fns.c (hashfn_eq, hashfn_eql, sxhash):

1150 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
1152 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
1153 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
1154 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
1157 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
1159 * image.c (xpm_make_color_table_h): Fix compiler error because
1160 make_hash_table changed.
1162 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
1164 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
1166 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
1168 Use ad-hoc comparison function for the profiler's hash-tables.
1169 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
1170 (make_log): Use them.
1171 (handle_profiler_signal): Don't inhibit quit any longer since we don't
1172 call Fequal any more.

1181 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
1182 (hash_lookup, hash_remove_from_table): Move assertion checking of
1183 hashfn result here. Check hash-equality before calling cmpfn.

1201 Shrink struct vectorlike_header to the only size field.
1202 * lisp.h (enum pvec_type): Avoid explicit enum member values.
1204 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and

1207 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
1208 information from the vector header. Adjust comment.

1223 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
1224 (large_vectors): Change type to struct large_vector.
1225 (allocate_vector_from_block): Simplify.
1226 (PSEUDOVECTOR_NBYTES): Replace with...

1232 (allocate_buffer): Use BUFFER_PVEC_INIT.
1233 (live_vector_p): Adjust to match large vector.
1234 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
1235 * buffer.h (struct buffer): Add next member.
1236 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):

1244 (xvecsize): New command.
1246 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
1248 * keyboard.c (event_to_kboard): Do not dereference
1249 frame_or_window field of SELECTION_REQUEST_EVENT
1250 and SELECTION_CLEAR_EVENT events (Bug#12814).
1251 * xterm.h (struct selection_input_event): Adjust comment.
1253 2012-11-07 Eli Zaretskii <eliz@gnu.org>
1255 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
1256 such as Scroll Lock, if the respective keys are treated as
1257 function keys, not as modifiers. This avoids destroying non-ASCII
1258 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
1260 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
1262 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
1264 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
1266 Restore some duplicate definitions (Bug#12814).
1267 This undoes part of the 2012-11-03 changes. Some people build
1268 with plain -g rather than with -g3, and they need the duplicate
1269 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
1270 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
1271 Define as macros, as well as as enums or as constants.
1273 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
1275 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
1276 to keypad keys (Bug#12816).
1278 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
1280 Minor adjustments of recently-changed frame functions.
1281 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
1282 known to be a frame (we're in the FRAMEP branch).
1283 * lisp.h (Qframep): Remove decl. frame.h declares this.
1284 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
1285 since they're meant for Lisp fixnum values.
1287 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
1289 * window.c (Fwindow_combination_limit): Revert to the only
1290 required argument and adjust docstring as suggested in
1291 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
1292 by Martin Rudalics <rudalics@gmx.at>.
1294 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>

1325 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
1326 (Fframe_face_alist): Use decode_live_frame.

1334 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
1335 (Fwindow_line_height): Use it.
1336 (Fwindow_fringes): Use list3.
1337 (Fwindow_scroll_bars): Use list4.
1338 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
1339 (Fwindow_combination_limit): Allow zero number of arguments.
1341 2012-11-05 Eli Zaretskii <eliz@gnu.org>
1343 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
1345 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
1346 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
1347 file descriptor 2 for standard error. (Bug#12805)
1349 2012-11-05 Chong Yidong <cyd@gnu.org>
1351 * process.c (wait_reading_process_output): Revert previous change.
1353 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
1355 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
1356 This removes code that has been obsolete since around 1990.
1357 * callproc.c (Fcall_process):
1359 * process.c (create_process):
1360 * term.c (dissociate_if_controlling_tty):
1361 Assume setsid exists.
1362 * callproc.c (child_setup): Assume setpgid exists and behaves as
1363 per POSIX.1-1988 or later.
1364 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
1365 * emacs.c (shut_down_emacs):
1366 * sysdep.c (sys_suspend, init_foreground_group):
1367 Assume getpgrp behaves as per POSIX.1-1998 or later.
1368 * msdos.c (setpgrp): Remove.
1369 (tcgetpgrp, setpgid, setsid): New functions.
1370 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
1371 * term.c (no_controlling_tty): Remove; unused.
1372 * w32proc.c (setpgrp): Remove.
1373 (setsid, tcgetpgrp): New functions.
1375 Simplify by assuming __fpending.
1376 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
1377 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
1378 Do not assume that __fpending's result fits in int.
1380 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
1382 Remove EMACS_OUTQSIZE+sleep hack.
1383 * dispnew.c (update_frame_1): Remove hack for terminals slower
1384 than 2400 bps, which throttled Emacs by having it sleep.
1385 This code hasn't worked since at least 2007, when the multi-tty stuff
1386 was added, and anyway those old terminals are long dead.
1387 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
1388 without the dispnew.c change, as dispnew.c doesn't include systty.h.
1390 Fix data-loss with --version (Bug#9574).
1391 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
1392 as we can't assume that emacs_strerror is initialized, and strerror
1393 is good enough here.
1394 (main): Invoke atexit earlier, to catch earlier instances of
1395 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
1397 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
1399 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
1400 (keyDown): Remap keypad keys to X11 virtual key codes.
1402 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
1404 Fix data-loss with --batch (Bug#9574).
1405 * emacs.c: Include <close-stream.h>.
1406 (close_output_streams): New function.
1407 (main): Pass it to atexit, so that Emacs closes stdout and stderr
1408 and handles errors appropriately.
1409 (Fkill_emacs): Don't worry about flushing, as close_output_stream
1412 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
1413 The symptom is a diagnostic "GLib-WARNING **: In call to
1414 g_spawn_sync(), exit status of a child process was requested but
1415 SIGCHLD action was set to SIG_IGN and ECHILD was received by
1416 waitpid(), so exit status can't be returned." The diagnostic
1417 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
1418 The real bug is a race condition between Emacs and glib: Emacs
1419 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
1420 so that glib can't find it. Work around the bug by invoking
1421 waitpid only on subprocesses that Emacs itself creates.
1422 * process.c (create_process, record_child_status_change):
1423 Don't use special value -1 in pid field, as the caller now must
1424 know the pid rather than having the callee infer it.
1425 The inference was sometimes incorrect anyway, due to another race.
1426 (create_process): Set new 'alive' member if child is created.
1427 (process_status_retrieved): New function.
1428 (record_child_status_change): Use it.
1429 Accept negative 1st argument, which means to wait for the
1430 processes that Emacs already knows about. Move special-case code
1431 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
1432 processes that have already been waited for, by testing and
1433 clearing new 'alive' member.
1434 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
1435 now does this internally.
1436 (handle_child_signal): Let record_child_status_change do all
1437 the work, since we do not want to reap all exited child processes,
1438 only the child processes that Emacs itself created.
1439 * process.h (Lisp_Process): New boolean member 'alive'.
1441 Omit duplicate definitions no longer needed with gcc -g3.
1442 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
1443 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
1444 Define only as macros. There's no longer any need to also define
1445 these symbols as enums or as constants, since we now assume
1446 gcc -g3 when debugging.
1448 2012-11-03 Eli Zaretskii <eliz@gnu.org>
1450 * lisp.mk: Adjust comments to the fact that term/internal is now
1451 loaded from loadup.el.
1453 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
1454 (msdos_fatal_signal): New function.
1455 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
1458 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
1459 for GCC versions before 4.
1460 (emacs_raise): Define to call msdos_fatal_signal.
1462 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
1463 iterator when starting in the middle of a display or overlay
1466 2012-11-03 Chong Yidong <cyd@gnu.org>
1468 * process.c (wait_reading_process_output): Clean up the last
1471 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
1473 * process.c (wait_reading_process_output): Avoid a race condition
1474 with SIGIO delivery (Bug#11536).
1476 2012-11-03 Chong Yidong <cyd@gnu.org>
1478 * buffer.c (cursor_type): Untabify docstring.
1480 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
1482 * frame.h (struct frame): Drop can_have_scroll_bars member
1483 which is meaningless for a long time. Adjust comments.
1484 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
1485 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
1487 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
1489 * window.c (decode_next_window_args): Update window arg after
1490 calling decode_live_window and so fix crash reported at
1491 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
1492 by Juanma Barranquero <lekktu@gmail.com>.
1493 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
1494 * font.c (Ffont_at): Likewise.
1496 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
1498 * widget.c (resize_cb): New function.
1499 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
1500 (EmacsFrameResize): Check if all is up to date before changing frame
1503 2012-11-02 Eli Zaretskii <eliz@gnu.org>
1505 Implement backtrace output for fatal errors on MS-Windows.
1506 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
1507 (BACKTRACE_LIMIT_MAX): New macro.
1508 (w32_backtrace): New function.
1509 (emacs_abort): Use w32_backtrace when the user chooses not to
1510 attach a debugger. Update the text of the abort dialog.
1512 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
1514 Window-related stuff cleanup here and there.
1515 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
1516 Use decode_any_window.
1517 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
1518 * xdisp.c (Fformat_mode_line): Likewise.
1519 * font.c (Ffont_at): Use decode_live_window.
1520 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
1521 * window.c (decode_next_window_args): Likewise.
1522 (decode_any_window): Remove static.
1523 * window.h (decode_any_window): Add prototype.
1524 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
1525 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
1528 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
1530 Remove pad from struct input_event.
1531 * termhooks.h (struct input_event): Remove padding field.
1533 * keyboard.c (event_to_kboard): Simplify because frame_or_window
1534 member is never cons for a long time. Adjust comment.
1535 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
1536 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
1537 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
1538 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
1540 2012-11-01 Eli Zaretskii <eliz@gnu.org>
1542 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
1544 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
1546 Fix crash when using Emacs as commit editor for git (Bug#12697).
1547 * callproc.c (setpgrp): Remove macro, as we now use setpgid
1548 and it is configured in conf_post.h.
1549 (Fcall_process): Don't invoke both setsid and setpgid; the former
1550 is enough, if it exists.
1551 * callproc.c (Fcall_process, child_setup):
1552 * process.c (create_process): Use setpgid.
1553 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
1555 * dispnew.c (init_display): Initialize the foreground group
1556 if we are running a tty display.
1557 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
1558 * lisp.h (init_foreground_group): New decl.
1559 * sysdep.c (inherited_pgroup): New static var.
1560 (init_foreground_group, tcsetpgrp_without_stopping)
1561 (narrow_foreground_group, widen_foreground_group): New functions.
1562 (init_sys_modes): Narrow foreground group.
1563 (reset_sys_modes): Widen foreground group.
1565 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
1567 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
1569 2012-10-31 Martin Rudalics <rudalics@gmx.at>
1571 * minibuf.c (read_minibuf): Restore current buffer since
1572 choose_minibuf_frame calling Fset_frame_selected_window may
1573 change it (Bug#12766).
1575 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
1577 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
1579 2012-10-30 Kenichi Handa <handa@gnu.org>
1581 * font.c (Ffont_at): If WINDOW is specified and it is not
1582 displaying the current buffer, signal an error.
1584 2012-10-29 Daniel Colascione <dancol@dancol.org>
1586 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
1587 In preparation for fixing bug#12739, move these functions from
1590 * coding.h, coding.c: ... to here, and compile them only when
1591 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
1592 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
1594 2012-10-28 Eli Zaretskii <eliz@gnu.org>
1596 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
1597 (timer_loop, getitimer, setitimer): Use it instead of
1598 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
1600 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
1603 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
1605 * nsterm.m (NO_APPDEFINED_DATA): New define.
1606 (last_appdefined_event_data): New variable
1607 (last_appdefined_event): Remove.
1608 (ns_select): Initialize t from last_appdefined_event_data instead
1609 of [last_appdefined_event data1].
1610 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
1611 remove last_appdefined_event (Bug#12698).
1613 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
1615 * frame.c (x_set_font): Catch internal error.
1617 2012-10-27 Eli Zaretskii <eliz@gnu.org>
1619 Avoid overflow in w32 implementation of interval timers.
1620 When possible, for ITIMER_PROF count only times the main thread
1622 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
1623 'volatile ULONGLONG' types. All the other data which was
1624 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
1625 (GetThreadTimes_Proc): New typedef.
1626 (w32_get_timer_time): New function, returns a suitable time value
1628 (timer_loop): Enter critical section when accessing ULONGLONG
1629 values of the itimer_data struct, as these accesses are no longer
1630 atomic. Call 'w32_get_timer_time' instead of 'clock'.
1631 Remove unused variable.
1632 (init_timers): Initialize s_pfn_Get_Thread_Times.
1633 (start_timer_thread): Don't assign itimer->caller_thread here.
1634 (getitimer): Assign itimer->caller_thread here.
1635 (setitimer): Always call getitimer to get the value of ticks_now.
1636 (sys_spawnve): Avoid compiler warning about format mismatch.
1638 2012-10-26 Eli Zaretskii <eliz@gnu.org>
1640 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
1641 mouse movement events if the menu bar is active. This avoids
1642 producing a busy "hour-glass" cursor by Windows if the mouse
1643 pointer is positioned over a tooltip shown for some menu item.
1645 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
1647 Don't assume process IDs fit in int.
1648 * emacs.c (shut_down_emacs) [!DOS_NT]:
1649 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
1650 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
1651 Use pid_t, not int, to store process IDs, as 'int'
1652 is not wide enough on a few platforms (e.g., AIX and IRIX).
1654 2012-10-23 Kenichi Handa <handa@gnu.org>
1656 The following change is to make face-font-rescale-alist work
1657 correctly for non-ASCII fonts.
1659 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
1660 (font_open_for_lface): Handle Vface_font_rescale_alist.
1662 2012-10-23 Chong Yidong <cyd@gnu.org>
1664 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
1666 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>

1670 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
1672 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
1675 2012-10-21 Glenn Morris <rgm@gnu.org>
1677 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
1679 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
1681 Port to OpenBSD 5.1.
1682 * frame.c (Fmouse_position, Fmouse_pixel_position):
1683 * xdisp.c (produce_stretch_glyph):
1684 Declare local vars only when they're needed.
1685 This is clearer and avoids a warning on OpenBSD about unused vars.
1686 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
1687 This is safer, and avoids OpenBSD warnings about unused vars.
1688 * keyboard.c (record_menu_key): Remove unnecessary decl.
1689 (poll_timer): Define only if POLL_FOR_INPUT is defined.
1690 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
1691 as our definition clashes with OpenBSD's.
1692 * xfaces.c (load_face_colors, check_lface_attrs)
1693 (get_lface_attributes_no_remap, get_lface_attributes)
1694 (lface_fully_specified_p, x_supports_face_attributes_p)
1695 (tty_supports_face_attributes_p, face_fontset, realize_face)
1696 (realize_x_face, realize_tty_face):
1697 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
1698 merely Lisp_Object *. This is more informative and avoids
1699 a warning on OpenBSD about accessing beyond an object's size.
1701 2012-10-20 Chong Yidong <cyd@gnu.org>
1703 * lread.c (Fload): Doc fix (Bug#12592).
1705 2012-10-19 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny change)
1707 * font.c (Ffont_at): Fix previous change.
1709 2012-10-19 Eli Zaretskii <eliz@gnu.org>
1711 * puresize.h (BASE_PURESIZE): Bump the base value to 1700000.
1712 See http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00593.html
1715 * alloc.c (NSTATICS): Decrease to 0x800.
1717 2012-10-19 Stefan Monnier <monnier@iro.umontreal.ca>

1724 * nsterm.m (ns_select): Check writefds before call to
1725 FD_ISSET (Bug#12668).
1727 2012-10-18 Daniel Colascione <dancol@dancol.org>
1729 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
1730 (staticpro): If we run out of staticpro slots, die with an
1731 informative error instead of just calling emacs_abort.
1733 2012-10-18 Martin Rudalics <rudalics@gmx.at>
1735 Fix two flaws reported by Dmitry Antipov.
1736 * window.c (Ftemp_output_buffer_show): Remove.

1757 (set_process_dir, sys_spawnve, register_child, sys_sleep, getwd)
1758 (sys_link): Add prototypes.
1760 * w32.c: Include w32select.h.
1761 (sys_access, e_malloc, sys_select): Add prototypes.

1776 * cygw32.c (Fcygwin_convert_path_to_windows)
1777 (Fcygwin_convert_path_from_windows): Use EQ to compare 2
1778 Lisp_Object values. (Bug#12661)
1780 * w32fns.c (w32_msg_pump): Use XIL instead of casting an integer
1781 to Lisp_Object. (Bug#12661)

1826 * dbusbind.c: Fix cygw32 build break when compiling with dbus
1827 enabled by undefining the symbol "interface", which the platform
1828 headers define to something incompatible.
1830 2012-10-14 Daniel Colascione <dancol@dancol.org>
1832 * image.c (init_tiff_functions, init_imagemagick_functions)
1833 (init_svg_functions): Fix cygw32 build break by using these
1834 functions only when WINDOWSNT _and_ HAVE_NTGUI.

1851 * fileio.c: Formatting fixes.
1853 2012-10-13 Paul Eggert <eggert@cs.ucla.edu>
1855 Fix some stat-related races.
1856 * fileio.c (Fwrite_region): Avoid race condition if a file is
1857 removed or renamed by some other process immediately after Emacs
1858 writes it but before Emacs stats it. Do not assume that stat (or
1860 * image.c (slurp_file): Resolve the file name with fopen + fstat
1861 rather than stat + fopen.

1889 * fileio.c (check_existing): New function.
1890 (make_temp_name, Ffile_exists_p, Ffile_writable_p): Call it
1891 instead of calling 'stat', when what's needed is to check whether
1892 a file exists. This avoids expensive system calls on MS-Windows.
1895 * w32.c (init_environment): Call 'check_existing' instead of 'stat'.
1897 * lread.c (openp) [WINDOWSNT]: Call 'access' instead of 'stat' to
1898 determine whether a file exists and is not a directory.
1900 * lisp.h (check_existing): Add prototype.
1902 2012-10-12 Jan Djärv <jan.h.d@swipnet.se>
1904 * nsfont.m (nsfont_open): Remove font cache, it is not GC correct.

1987 (detect_input_pending_run_timers):
1988 * process.c (wait_reading_process_output):
1989 Use unsigned for counter where wraparound-on-overflow is desired,
1990 since unsigned is guaranteed to have that behavior and signed is not.
1991 (read_char): Use ptrdiff_t for string length.
1992 (get_input_pending): Remove first argument, since it was always
1993 the same pointer-to-int (now pointer-to-boolean) &input_pending,
1994 and behave as if it had that value. Return new value of
1995 input_pending. All callers changed.
1996 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
1997 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's
1999 * keymap.c (push_key_description): Omit last arg, which was always 1.
2000 All callers changed.
2002 * regex.c (immediate_quit) [emacs]: Remove duplicate decl.
2004 2012-10-10 Juanma Barranquero <lekktu@gmail.com>

2020 Don't include termopts.h.
2022 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>
2024 * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers.
2026 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
2028 * commands.h (immediate_quit): Remove duplicate decl.
2030 2012-10-09 Jan Djärv <jan.h.d@swipnet.se>
2032 * nsfont.m (Vfonts_in_cache): Remove, not needed as font.c handles

2035 (syms_of_nsfont): Remove initialization of Vfonts_in_cache.
2037 2012-10-09 Eli Zaretskii <eliz@gnu.org>
2039 * w32fns.c (w32_last_error): Change the return value to DWORD, to
2040 match what GetLastError returns. Explain why the function is
2043 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
2044 'is_tooltip_frame', to avoid confusion with its global namesake.
2046 2012-10-08 Daniel Colascione <dancol@dancol.org>
2048 * xdisp.c (start_hourglass): Call w32_note_current_window when
2049 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
2050 build that caused Emacs to display the hourglass cursor forever.
2052 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
2053 which is broken under remote desktop, calculate the number of
2054 colors available for a display based on the display's number of
2055 planes and number of bits per pixel per plane. (bug#10397).
2057 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
2059 * nsfont.m (Vfonts_in_cache): New variable.
2060 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
2061 are used. Add cached fonts to Vfonts_in_cache.
2062 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
2064 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
2066 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
2068 (FONT_H): Define after FRAME_H.
2069 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
2070 Update dependencies.
2072 * w32term.c: Remove leftover declaration of keyboard_codepage.
2074 2012-10-08 Eli Zaretskii <eliz@gnu.org>
2076 * makefile.w32-in (FONT_H): Add $(FRAME_H).
2077 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
2078 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
2079 (GLOBAL_SOURCES): Add cygw32.c.
2080 ($(BLD)/unexw32.$(O)):
2082 ($(BLD)/w32console.$(O)):
2083 ($(BLD)/w32fns.$(O)):
2084 ($(BLD)/w32heap.$(O)):
2085 ($(BLD)/w32menu.$(O)):
2086 ($(BLD)/w32proc.$(O)): Add w32common.h.
2088 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
2090 (x_to_w32_color): Don't modify the argument, modify a copy instead.
2092 2012-10-08 Daniel Colascione <dancol@dancol.org>
2094 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
2095 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
2096 accidental message numbering hole. Change other messages to
2099 * w32select.h (HAVE_W32SELECT): Remove.
2101 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
2102 w32common.h instead of w32heap.h.
2104 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
2105 (get_allocation_unit, get_processor_type, get_w32_major_version)
2106 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
2107 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
2108 (OS_NT, os_subtype, cache_system_info): Move declarations to
2111 * w32heap.c: Include w32common.h.
2112 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
2113 (w32_minor_version, w32_build_number, w32_subtype):
2114 Remove duplicate definitions.
2116 * w32fns.c: Include w32common.h; include w32heap.h only in
2119 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
2120 Use `report_file_error' instead of `error' in order to better
2121 inform users of what went wrong. Increase NTGUI_UNICODE file
2122 dialog box file name length to 32k, the maximum allowed by the NT
2125 * w32common.h: New file.
2126 (ROUND_UP, ROUND_DOWN, get_page_size)
2127 (get_allocation_unit, get_processor_type, get_w32_major_version)
2128 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
2129 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
2130 (OS_NT, os_subtype, cache_system_info): Move here.
2132 * unexw32.c, unexcw.c: Include w32common.h.
2134 * emacs.c (main): Use (defined (WINDOWSNT) || defined
2135 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
2136 to call syms_of_w32select.
2138 * cygw32.h: Remove obsolete EXFUN declarations.
2140 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
2142 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
2143 of w32inevt.o from SOME_MACHINE_OBJECTS.
2145 2012-10-08 Daniel Colascione <dancol@dancol.org>
2147 * image.c: Permanent fix for JPEG compilation issue --- limit
2148 jpeglib `boolean' redefinition to Cygwin builds.
2150 2012-10-08 Eli Zaretskii <eliz@gnu.org>
2152 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
2154 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
2157 2012-10-08 Daniel Colascione <dancol@dancol.org>
2159 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
2160 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
2161 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
2162 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
2163 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
2164 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
2165 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
2166 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
2167 now a supported configuration.
2169 * Makefile.in: consolidate image variables into LIBIMAGE; add
2170 W32_OBJ and W32_LIBS. Compile new files.
2173 (_DebPrint) declare tracing facility for W32 debugging. We need
2174 to unify tracing later.
2176 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
2177 unconditional use of W32 Unicode functions. Cygwin runs only on
2178 100% Unicode operating systems.
2180 * cygw32.c: New file. Define Cygwin-specific facilities.
2181 (Fcygwin_convert_path_to_windows)
2182 (Fcygwin_convert_path_from_windows): New user functions for
2183 accessing Cygwin path-munging routines.
2185 * cygw32.h: New file.
2186 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
2187 UTF-16LE strings temporarily inside non-Lisp-visible string
2190 (w32_strerror): Just what it says on the tin.
2192 * emacs.c: Make the NS fork-then-exec code for daemon-launching
2193 also run for Cygwin; both systems have the same problem with using
2194 GUI facilities in a forked child. Also call syms_of_cygw32,
2195 syms_of_w32select in correct places.
2197 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
2198 needs fork-then-exec for daemon launching.
2200 * font.h: Include frame.h.
2202 * image.c: Use the image library cache machinery only when we're
2203 compiling for native WINDOWSNT; Cygwin can use shared libraries
2204 like any other Unixlike system.
2206 * keyboard.c: Clarify a comment regarding the input loop.
2208 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
2209 functions directly instead of trying to detect at runtime that our
2210 host operating system supports them. We make this change for two
2211 reasons: Cygwin lacks support for the multibyte character
2212 conversion functions used by the legacy menu code, and Cygwin
2213 never needs to rely on non-Unicode APIs.
2215 * unexw32.c (hinst): Declare extern.
2217 * w32.c: Change header order;
2218 (w32_strerror): Move to w32fns.c because we need it for
2219 non-WINDOWSNT builds.
2221 * w32.h: Add #error macro to make sure we don't include w32.h for
2222 Cygwin builds. Remove w32select declarations.
2224 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
2225 w32fns.c. w32console.c is WINDOWSNT-only.
2227 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
2228 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
2230 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
2231 (w32_major_version, w32_minor_version, w32_build_number)
2232 (os_subtype, sound_type): Define here
2233 (w32_defined_color): Make color parameter const for consistency
2234 with other _defined_color functions.
2235 (w32_createwindow): Unconditionally call w32_init_class instead of
2236 doing so only when hprevinst is non-NULL. Plumbing hprevinst
2237 through the code is complex and unnecessary because class
2238 registration is practically free.
2239 (w32_name_of_message): New EMACSDEBUG-only function.
2240 (Fset_message_beep): Move here
2241 (Fx_open_connection): Require that the display name for Windows be
2242 "w32" for consistency, emacsclient disambiguation, and maybe, one
2243 day, multi-window-system support.
2244 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
2245 Cygwin files for W32 GUI facilities, since these clearly don't
2246 expect Cygwin names.
2247 (_DebPrint): Define.
2248 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
2249 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
2250 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
2251 (w32_last_error): Remove.
2253 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
2255 * w32heap.c (syspage_mask): Declare here.
2256 (cache_system_info): Remove.
2258 * w32inevt.c (faked_key): Define globally, not statically.
2259 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
2260 (w32_console_toggle_lock_key): Move to w32fns.c.
2262 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
2264 * w32proc.c (_DebPrint): Move to w32fns.c.
2265 * w32select.c: Include string.h, stdio.h for Cygwin.
2266 * w32select.h: New File.
2268 * w32term.c: Include io.h for non-CYGWIN builds; needed for
2270 (w32_message_fd): New variable. Under Cygwin, holds the file
2271 descriptor the system used to tell us about pending thread
2274 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
2275 that prevented compilation under non-WINDOWSNT systems.
2277 (w32_initialize): Open /dev/windows and assign it to
2278 w32_message_fd. Provide w32 feature.
2280 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
2281 (WM_EMACS_INPUT_READY): add.
2282 (prepend_msg, w32_message_fd): Declare globally.
2285 (keyboard_handle): Use only when WINDOWSNT.
2286 (notify_msg_ready): New function. Posts a message to the main
2287 thread's message queue under CYGWIN, which wakes up the main
2288 thread from select(2) by making the /dev/windows file descriptor
2289 ready. Under WINDOWSNT, it sets an event the same way the old
2292 (post, prepend_msg): Actually call notify_msg_ready instead of
2293 setting the input event directly.
2295 2012-10-07 Eli Zaretskii <eliz@gnu.org>
2297 * ralloc.c (relinquish): If a heap is ready to be relinquished,
2298 but it still has blocs in it, don't return it to the system,
2299 instead of aborting. (Bug#12402)
2301 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
2303 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
2305 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
2306 MAC_OS_X_VERSION_10_6.
2307 (syms_of_nsterm): Remove comment about Panther and above for
2309 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.

2311 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
2313 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
2314 MAC_OS_X_VERSION_10_4.
2316 * nsmenu.m (fillWithWidgetValue:): Remove code for <
2317 MAC_OS_X_VERSION_10_2.
2319 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
2321 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
2322 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
2324 * nsterm.m (ns_in_resize): Remove (Bug#12479).
2325 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
2326 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
2327 Remove ns_in_resize check.
2328 (ns_clear_frame_area): Remove resize handle code.
2330 * nsfns.m (ns_in_resize): Remove.
2331 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
2332 Remove ns_in_resize check.
2334 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
2336 Improve sys_siglist detection.
2337 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
2338 defined as a macro, as is done in Solaris.
2339 (sys_siglist_entries): New macro.
2340 (save_strsignal): Use it.
2341 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
2342 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
2344 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
2346 * nsfns.m (Fx_create_frame): Call x_default_parameter with
2347 fullscreen/Fullscreen.
2349 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
2350 tobar_height is new.
2352 * nsterm.m (x_make_frame_visible): Check for fullscreen.
2353 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
2354 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
2355 (windowDidResize:): Check for correct window if old style fullscreen.
2356 Capitalize word in comment. Remove incorrect comment.
2357 (initFrameFromEmacs:): tbar_height renamed tibar_height.
2358 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
2359 error in drawing background.
2360 (toggleFullScreen:): Remove comment. Rearrange calls.
2361 Set toolbar values to zero, save old height in tobar_height.

2363 (canBecomeMainWindow): New function.
2365 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
2367 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
2369 2012-10-05 Eli Zaretskii <eliz@gnu.org>
2371 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
2373 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
2374 that time stamps of directories could also be changed.
2375 Don't request the too broad GENERIC_WRITE, only the more restrictive
2376 FILE_WRITE_ATTRIBUTES access rights.
2378 * fileio.c (Fset_file_times): Special-case ignoring errors for
2379 directories only on MSDOS, not on MS-Windows.
2381 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
2383 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
2385 2012-10-04 Eli Zaretskii <eliz@gnu.org>
2387 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
2388 see whether CreateFile failed.
2390 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
2392 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
2393 to avoid similar races.
2394 * keyboard.c (pending_signals): Now bool, not int.
2396 Port timers to OpenBSD, plus check for timer failures.
2397 OpenBSD problem reported by Han Boetes.
2398 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
2400 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
2401 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
2402 like OpenBSD, which has timer_settime but does not declare it.
2403 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
2404 whether to use itimerspec-related primitives. All uses of
2405 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
2407 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
2409 * profiler.c (handle_profiler_signal): Fix a malloc race
2410 that caused Emacs to hang on Fedora 17 when profiling Lisp.
2412 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
2414 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
2416 2012-10-02 Eli Zaretskii <eliz@gnu.org>
2418 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
2419 consistent with the change in return value of 'safe_strsignal'.
2421 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
2423 Prefer plain 'static' to 'static inline' (Bug#12541).
2424 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
2425 (bidi_set_sor_type, bidi_push_embedding_level)
2426 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)

2431 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
2432 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
2433 Now 'static', not 'static inline'.
2435 Count overruns when profiling; change units to ns.
2436 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
2437 Give extra weight to samples after overruns, to attempt to count
2438 the time more accurately.
2439 (setup_cpu_timer): Change sampling interval units from ms to ns, since
2440 the underlying primitives nominally do ns.
2441 (Fprofiler_cpu_start): Document the change. Mention that
2442 the sampling intervals are only approximate.
2444 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
2446 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
2448 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
2449 case for the special 0 coding-system.
2451 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
2452 (Fmake_overlay): Remove redundant tests.
2453 (fix_start_end_in_overlays): Remove redundant recentering.
2455 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
2457 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
2458 Update dependencies.
2460 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
2462 Fix a malloc race condition involving strsignal.
2463 A signal can arrive in the middle of a malloc, and Emacs's signal
2464 handler can invoke strsignal, which can invoke malloc, which is
2465 not portable. This race condition bug makes Emacs hang on GNU/Linux.
2466 Fix it by altering the signal handler so that it does not invoke
2468 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
2469 * process.c (status_message): Use const pointer, in case strsignal
2470 is #defined to safe_strsignal.
2471 * sysdep.c (sys_siglist, init_signals): Always define and
2472 initialize a substitute sys_siglist if the system does not define
2473 one, even if HAVE_STRSIGNAL.
2474 (safe_strsignal): Rename from strsignal. Always define,
2475 using sys_siglist. Return a const pointer.
2476 * syssignal.h (safe_strsignal): New decl.
2477 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
2479 2012-10-01 Eli Zaretskii <eliz@gnu.org>
2481 * w32proc.c (timer_loop): Fix code that waits for timer
2482 expiration, to avoid high CPU usage.
2484 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
2486 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
2487 (sweep_weak_table): Remove redundant prototypes.
2489 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
2491 * emacs.c: Move the inclusion of TERM_HEADER after including
2492 windows.h on WINDOWSNT. This avoids compilation problems with
2495 2012-10-01 Eli Zaretskii <eliz@gnu.org>
2497 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
2498 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
2499 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
2500 as the previous version used 'void *'.
2502 * ralloc.c (ROUNDUP): Fix last change.
2503 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
2506 * w32proc.c <disable_itimers>: New static flag.
2507 (init_timers): Initialize it to zero, after creating the critical
2508 sections used by the timer threads.
2509 (term_timers): Set to 1 before deleting the critical sections.
2510 (getitimer, setitimer): If disable_itimers is non-zero, return an
2511 error indication without doing anything. Reported by Fabrice
2512 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
2513 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
2515 [!HAVE_SETITIMER]: Behave as the previous version that didn't
2518 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
2519 term_ntproc after all the other bookkeeping, to get timers working
2520 as long as possible.
2522 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
2524 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
2525 Suggested by Juri Linkov in
2526 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
2528 Prefer plain 'static' to 'static inline' (Bug#12541).
2529 With static functions, modern compilers inline pretty well by
2530 themselves; advice from programmers often hurts as much as it helps.
2531 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
2532 this change shrinks the text size of the Emacs executable by 1.1%
2533 without affecting CPU significantly in my benchmark.
2534 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)

2616 Revert the FOLLOW-SYMLINKS change for file-attributes.
2617 Doing it right would require several changes to Tramp, and there's
2618 not enough time to get that tested before the freeze today.
2619 * dired.c (directory_files_internal, Ffile_attributes):
2622 * frame.c (x_report_frame_params): Port better to wider ints.
2623 Do not assume that EMACS_UINT is the same width as uprintmax_t,
2624 or that pointers can be printed in 15 decimal digits.
2625 Avoid GCC warnings if EMACS_UINT is wider than a pointer.

2747 * w32.h (init_timers, term_timers): Add prototypes.
2749 2012-09-30 Kenichi Handa <handa@gnu.org>
2751 * coding.c (decode_coding_ccl, encode_coding_ccl): Pay attention
2752 to the buffer relocation which may be caused by ccl_driver.

2803 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
2805 * syssignal.h (PROFILER_CPU_SUPPORT): Don't define if PROFILING.
2806 Suggested by Eli Zaretskii in
2807 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00811.html>.
2809 2012-09-30 Eli Zaretskii <eliz@gnu.org>
2811 * profiler.c (Fprofiler_cpu_stop): Use timer_settime only if
2812 HAVE_TIMER_SETTIME is defined.
2814 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
2816 Profiler improvements: more-accurate timers, overflow checks.
2817 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
2818 signal.h, setjmp.h. Include systime.h instead.
2819 (saturated_add): New function.
2820 (record_backtrace, current_sample_interval): Use EMACS_INT, not size_t.
2821 (record_backtrace, handle_profiler_signal): Saturate on fixnum overflow.
2822 (profiler_timer, profiler_timer_ok) [HAVE_TIMER_SETTIME]:
2824 (enum profiler_cpu_running): New enum.
2825 (profiler_cpu_running): Now of that enum type, not bool.
2826 All uses changed to store the new value.
2827 (handle_profiler_signal): Rename from sigprof_handler_1,
2828 for consistency with other handlers. Do not check whether
2829 cpu_log is a hash-table if garbage collecting, since it
2830 doesn't matter in that case.
2831 (deliver_profiler_signal): Rename from sigprof_handler,
2832 for consistency with other handlers.
2833 (setup_cpu_timer): New function, with much of what used to be in
2834 Fprofiler_cpu_start. Check for out-of-range argument.
2835 Prefer timer_settime if available, and prefer
2836 thread cputime clocks, then process cputime clocks, then
2837 monotonic clocks, to the old realtime clock. Use make_timeval
2838 to round more-correctly when falling back to setitimer.
2839 (Fprofiler_cpu_start): Use it.
2840 (Fprofiler_cpu_stop): Prefer timer_settime if available.
2841 Don't assume that passing NULL as the 2nd argument of setitimer
2842 is the same as passing a pointer to all-zero storage.
2843 Ignore SIGPROF afterwards.
2844 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
2845 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
2846 non-fatal signal handlers. Ignore SIGPROF on startup.
2847 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
2848 in profiler.c, since sysdep.c now uses it.
2850 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.
2851 Suggested by Eli Zaretskii in
2852 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.

2865 (Fbacktrace_frame): Adjust accordingly.
2867 2012-09-28 Glenn Morris <rgm@gnu.org>
2869 * eval.c (Frun_hook_with_args, Frun_hook_with_args_until_success)

2902 2012-09-26 Paul Eggert <eggert@cs.ucla.edu>
2904 * character.h (MAYBE_UNIFY_CHAR): Remove.
2905 * charset.c, charset.h (maybe_unify_char): Now static.
2906 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
2907 Since this stuff is now private to charset.c, there's no need for
2908 a public macro and no need to inline by hand.

2941 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>
2943 Prefer POSIX timers if available.
2944 They avoid a race if the timer is too close to the current time.
2945 * atimer.c (alarm_timer, alarm_timer_ok) [SIGEV_SIGNAL]: New static vars.
2946 (set_alarm) [SIGEV_SIGNAL]: Use POSIX timers if available.
2947 (init_atimer) [SIGEV_SIGNAL]: Initialize them.
2949 2012-09-25 Eli Zaretskii <eliz@gnu.org>
2951 * coding.c (CHAR_STRING_ADVANCE_NO_UNIFY): Make it an alias of
2952 CHAR_STRING_ADVANCE.
2953 (STRING_CHAR_ADVANCE_NO_UNIFY): Make it an alias of
2954 STRING_CHAR_ADVANCE.

2970 (globals_of_w32) <Vlibrary_cache>: Do not initialize.
2972 * w32.h (Vlibrary_cache): Do not declare.
2974 2012-09-25 Eli Zaretskii <eliz@gnu.org>
2976 * w32proc.c (sys_signal): Handle all signals defined by the
2977 MS-Windows runtime, not just SIGCHLD. Actually install the signal
2978 handlers for signals supported by Windows. Don't override
2979 term_ntproc as the handler for SIGABRT.
2980 (sigaction): Rewrite to call sys_signal instead of duplicating its
2982 (sys_kill): Improve commentary.
2984 * w32.c (term_ntproc): Accept (and ignore) one argument, for
2985 consistency with a signature of a signal handler. All callers
2987 (init_ntproc): Accept an argument DUMPING. If dumping, don't
2988 install term_ntproc as a signal handler for SIGABRT, as that
2989 should be done by the dumped Emacs.
2991 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
2993 * w32select.c (term_w32select): Protect against repeated
2994 invocation by setting clipboard_owner to NULL after calling
2997 * emacs.c (shut_down_emacs, main): Adapt the calls to init_ntproc
2998 and term_ntproc to their modified signatures.
3000 * character.c (char_string, string_char): Remove calls to
3001 MAYBE_UNIFY_CHAR. See the discussion starting at

3009 2012-09-24 Stefan Monnier <monnier@iro.umontreal.ca>
3011 * bytecode.c (exec_byte_code): Signal an error instead of aborting,
3012 when encountering an unknown bytecode.
3014 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
3016 image.c, indent.c: Use bool for booleans.
3017 * dispextern.h (struct image_type): Members valid_p, load, init

3019 * image.c: Omit unnecessary static decls.
3020 (x_create_bitmap_mask, x_build_heuristic_mask):

3058 Move pid_t related decls out of lisp.h.
3059 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
3060 (interruptible_wait_for_termination):
3061 Move these decls from lisp.h to syswait.h, since they use pid_t.
3062 Needed on FreeBSD; see Herbert J. Skuhra in
3063 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.

3110 2012-09-23 Eli Zaretskii <eliz@gnu.org>
3112 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
3113 fatal_error_backtrace.
3115 * w32proc.c (sys_kill): Undo last change: don't do anything when
3116 invoked to deliver SIGABRT to our own process. This is now
3117 handled by emacs_raise.
3119 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
3121 * w32term.c (w32_read_socket): Remove leftover reference to
3122 interrupt_input_pending.
3124 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
3126 Do not use SA_NODEFER.
3127 Problem reported by Dani Moncayo in
3128 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
3130 * sysdep.c (emacs_abort): Do not reset signal handler.
3131 * emacs.c (terminate_due_to_signal): Reset signal handler here.
3132 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
3133 wanted even on POSIXish hosts, and it doesn't work on Windows.
3135 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
3137 * xterm.c (x_term_init): Call fixup_locale before and after calling
3138 gtk_init (Bug#12392).
3140 2012-09-23 Chong Yidong <cyd@gnu.org>
3142 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
3143 Vdynamic_library_alist.
3145 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
3146 (Fgnutls_available_p): Caller changed.
3148 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
3149 (Flibxml_parse_xml_region): Likewise.
3151 * dispextern.h (struct image_type): Remove arg from init function.
3153 * image.c (Finit_image_library, lookup_image_type)
3154 (define_image_type): Remove now-unneeded second arg.
3155 (init_xpm_functions, init_png_functions, init_jpeg_functions)
3156 (init_tiff_functions, init_gif_functions, init_svg_functions):
3157 Arglist and w32_delayed_load calling convention changed.
3158 (gs_type): Remove init_gs_functions; there is no such function.
3159 (valid_image_p, make_image): Fix caller to lookup_image_type.
3161 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
3163 Simplify and avoid signal-handling races (Bug#12471).
3165 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
3166 Avoid recursive loop if there's a fatal error in the function itself.
3167 * atimer.c (pending_atimers):
3168 * blockinput.h: Don't include "atimer.h"; no longer needed.
3169 (interrupt_input_pending): Remove. All uses removed.
3170 pending_signals now counts both atimers and ordinary interrupts.
3171 This is less racy than having three separate pending-signal flags.
3172 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
3174 Rename from their upper-case counterparts BLOCK_INPUT,
3175 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
3176 INPUT_BLOCKED_P, and turn into functions. All uses changed.
3177 This makes it easier to access volatile variables more accurately.
3178 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
3179 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
3180 that's more reliable if the code is buggy and sets
3181 interrupt_input_blocked to a negative value. All uses changed.
3182 * atimer.c (deliver_alarm_signal):
3183 Remove. No need to deliver this to the parent; any thread can
3184 handle this signal now. All uses replaced by underlying handler.
3185 * atimer.c (turn_on_atimers):
3186 * dispnew.c (handle_window_change_signal):
3187 * emacs.c (handle_danger_signal):
3188 * keyboard.c (kbd_buffer_get_event):
3189 Don't reestablish signal handler; not needed with sigaction.
3190 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
3192 Rework to avoid unnecessary accesses to volatile variables.
3193 (UNBLOCK_INPUT_TO): Now a function.
3194 (totally_unblock_input, unblock_input): New decls.
3195 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
3196 (init_data): Remove. Necessary stuff now done in init_signal.
3197 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
3198 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
3199 (fatal_error_code): Remove; no longer needed.
3200 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
3201 it doesn't always backtrace. All uses changed. No need to reset
3202 signal to default, since sigaction and/or die does that for us now.
3203 Use emacs_raise (FOO), not kill (getpid (), FOO).
3204 (main): Check more-accurately whether we're dumping.
3205 Move fatal-error setup to sysdep.c
3206 * floatfns.c: Do not include "syssignal.h"; no longer needed.
3207 * gtkutil.c (xg_get_file_name, xg_get_font):
3208 Remove no-longer-needed signal-mask manipulation.
3209 * keyboard.c, process.c (POLL_FOR_INPUT):
3210 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
3211 * keyboard.c (read_avail_input): Remove.
3212 All uses replaced by gobble_input.
3213 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
3214 (kbd_buffer_store_event_hold, gobble_input):
3215 (record_asynch_buffer_change) [USABLE_SIGIO]:
3216 (store_user_signal_events):
3217 No need to mess with signal mask.
3218 (gobble_input): If blocking input and there are terminals, simply
3219 set pending_signals to 1 and return. All hooks changed to not
3220 worry about whether input is blocked.
3221 (process_pending_signals): Clear pending_signals before processing
3222 them, in case a signal comes in while we're processing.
3223 By convention callers now test pending_signals before calling us.
3224 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
3225 New functions, to support changes to blockinput.h.
3226 (handle_input_available_signal): Now extern.
3227 (reinvoke_input_signal): Remove. All uses replaced by
3229 (quit_count): Now volatile, since a signal handler uses it.
3230 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
3231 All callers changed. Block SIGINT only if not already blocked.
3232 Clear sigmask reliably, even if Fsignal returns, which it can.
3233 Omit unnecessary accesses to volatile var.
3234 (quit_throw_to_read_char): No need to restore sigmask.
3235 * keyboard.c (gobble_input, handle_user_signal):
3236 * process.c (wait_reading_process_output):
3237 Call signal-handling code rather than killing ourselves.
3238 * lisp.h: Include <float.h>, for...
3239 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
3240 (pending_signals): Now volatile.
3241 (syms_of_data): Now const if IEEE floating point.
3242 (handle_input_available_signal) [USABLE_SIGIO]:
3243 (terminate_due_to_signal, record_child_status_change): New decls.
3244 * process.c (create_process): Avoid disaster if memory is exhausted
3245 while we're processing a vfork, by tightening the critical section
3247 (send_process_frame, process_sent_to, handle_pipe_signal)
3248 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
3250 (send_process): No need for setjmp/longjmp any more, since the
3251 SIGPIPE stuff is now gone. Instead, report an error if errno
3253 (record_child_status_change): Now extern. PID and W are now args.
3254 Return void, not bool. All callers changed.
3255 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
3256 Remove. All uses removed. This bug should be fixed now in a
3258 (wait_for_termination_1): Use waitpid rather than sigsuspend,
3259 and record the child status change directly. This avoids the
3260 need to futz with the signal mask.
3261 (process_fatal_action): Move here from emacs.c.
3262 (emacs_sigaction_flags): New function, containing
3263 much of what used to be in emacs_sigaction_init.
3264 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
3265 caught by emacs, to make races less likely.
3266 (deliver_process_signal): Rename from handle_on_main_thread.
3268 (BACKTRACE_LIMIT_MAX): Now at top level.
3269 (thread_backtrace_buffer, threadback_backtrace_pointers):
3271 (deliver_thread_signal, deliver_fatal_thread_signal):
3272 New functions, for more-accurate delivery of thread-specific signals.
3273 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
3274 (deliver_arith_signal): Handle in this thread, not
3275 in the main thread, since it's triggered by this thread.
3276 (maybe_fatal_sig): New function.
3277 (init_signals): New arg DUMPING so that we can be more accurate
3278 about whether we're dumping. Caller changed.
3279 Treat thread-specific signals differently from process-general signals.
3280 Block all signals while handling fatal error; that's safer.
3281 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
3283 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
3284 Ignore SIGPIPE unless batch.
3285 (emacs_backtrace): Output backtrace for the appropriate thread,
3286 which is not necessarily the main thread.
3287 * syssignal.h: Include <stdbool.h>.
3288 (emacs_raise): New macro.
3289 * xterm.c (x_connection_signal): Remove; no longer needed
3290 now that we use sigaction.
3291 (x_connection_closed): No need to mess with sigmask now.
3292 (x_initialize): No need to reset SIGPIPE handler here, since
3293 init_signals does this for us now.
3295 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
3297 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
3298 background rect may be larger (Bug#12245).
3300 2012-09-23 Chong Yidong <cyd@gnu.org>
3302 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
3304 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
3306 * .gdbinit: Just stop at fatal_error_backtrace.
3307 See Stefan Monnier's request in
3308 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
3309 Remove no-longer-used query of system type.
3311 2012-09-22 Chong Yidong <cyd@gnu.org>
3313 * search.c (Freplace_match): Doc fix (Bug#12325).
3315 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
3317 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
3318 (Fline_end_position): Doc fix.
3320 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
3322 2012-09-22 Chong Yidong <cyd@gnu.org>
3324 * dispextern.h (struct image_type): Add new slot, storing a type
3325 initialization function.
3327 * image.c (define_image_type): Call the image initializer function
3328 if it is defined. Arguments and return value changed.
3329 (valid_image_p, make_image): Callers changed.
3330 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
3331 (gif_type, imagemagick_type, svg_type, gs_type):
3332 Add initialization functions.
3333 (Finit_image_library): Call lookup_image_type.
3334 (CHECK_LIB_AVAILABLE): Macro deleted.
3335 (lookup_image_type): Call define_image_type here, rather than via
3336 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
3337 (syms_of_image): Move define_image_type calls for xbm_type and
3338 pbm_type to lookup_image_type.
3340 2012-09-22 Eli Zaretskii <eliz@gnu.org>
3342 * keyboard.c (timer_check_2): Move calculation of 'timers' and
3343 'idle_timers' from here ...
3344 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
3345 lists, to avoid infloops when the timer does something stupid,
3346 like reinvoke itself with the same or smaller time-out.
3349 2012-09-22 Martin Rudalics <rudalics@gmx.at>
3351 * window.c (Fsplit_window_internal): Handle only Qt value of
3352 Vwindow_combination_limit separately.
3353 (Qtemp_buffer_resize): New symbol.
3354 (Vwindow_combination_limit): New default value.
3357 2012-09-22 Eli Zaretskii <eliz@gnu.org>
3359 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
3360 the new overlay string. (Bug#10159)
3362 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
3364 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
3365 or that fprintf is async-signal-safe. POSIX doesn't require
3368 2012-09-22 Chong Yidong <cyd@gnu.org>
3370 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
3373 2012-09-22 Kenichi Handa <handa@gnu.org>
3375 * composite.c (composition_reseat_it): Handle the case that a
3376 grapheme cluster is not covered by a single font (Bug#12352).
3378 2012-09-21 Chong Yidong <cyd@gnu.org>
3380 * image.c (define_image_type): Avoid adding duplicate types to
3381 image_types (Bug#12463). Suggested by Jörg Walter.
3383 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3385 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
3386 (print_load_command_name): Add case LC_DATA_IN_CODE.
3387 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
3389 2012-09-21 Glenn Morris <rgm@gnu.org>
3391 * eval.c (Frun_hook_with_args_until_success)
3392 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
3394 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
3396 * fileio.c (Ffile_selinux_context): Only call freecon when
3397 lgetfilecon succeeded.
3398 (Fset_file_selinux_context): Likewise. (Bug#12444)
3400 2012-09-21 Eli Zaretskii <eliz@gnu.org>
3402 * xdisp.c (try_window_reusing_current_matrix): Under bidi
3403 reordering, locate the cursor by calling set_cursor_from_row; if
3404 that fails, clear the desired glyph matrix before returning a
3405 failure indication to the caller. Fixes leaving garbled display
3406 when fast scrolling with a down-key. (Bug#12403)
3407 (compute_stop_pos_backwards): Fix a typo that caused crashes while
3408 scrolling through multibyte text.
3410 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
3412 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
3413 calling mark_vectorlike since that's the one that marks the window.
3414 (mark_discard_killed_buffers): Mark the final cdr.
3415 * window.h (struct window): Move prev/next_buffers to the
3416 non-standard fields.
3417 * window.c (make_window): Initialize prev/next_buffers manually.
3419 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
3421 Omit unused arg EXPECTED from socket hooks.
3422 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
3423 * nsterm.m (ns_term_init):
3424 * termhooks.h (struct terminal.read_socket_hook):
3425 * w32inevt.c (w32_console_read_socket):
3426 * w32term.c (w32_read_socket):
3427 * xterm.c (XTread_socket):
3428 Omit unused arg EXPECTED. All callers changed.
3429 (store_user_signal_events): Return void, not int, since callers no
3430 longer care about the return value. All uses changed.
3432 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
3434 * w32gui.h (XParseGeometry): Do not declare.
3436 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
3438 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
3439 Ignore 'expected'. See Eli Zaretskii in
3440 <http://bugs.gnu.org/12471#8> (last line).
3442 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
3443 (XParseGeometry): Now static. Substitute extremal values for
3444 values that are out of range.
3446 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
3448 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
3450 * nsfns.m (XParseGeometry): Remove.
3451 (Fx_create_frame): Call x_set_offset to correctly interpret
3452 top_pos in geometry.
3454 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
3455 (Fx_parse_geometry): If there is a space in string, call
3456 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
3458 2012-09-17 Eli Zaretskii <eliz@gnu.org>
3460 * search.c (scan_buffer): Use character positions in calls to
3461 region_cache_forward and region_cache_backward, not byte
3462 positions. (Bug#12196)
3464 * w32term.c (w32_read_socket): Set pending_signals to 1, like
3465 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
3467 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
3468 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
3469 emacs_blocked_malloc, now deleted.
3471 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
3473 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
3474 The workaround was for improving performance on Solaris 2.4, but
3475 is getting in the way now. Emacs will still work if someone is
3476 still running Solaris 2.4 in a museum somewhere; Sun dropped
3477 support for Solaris 2.4 in 2003.
3478 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
3479 * process.c (create_process) [HAVE_WORKING_VFORK]:
3480 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
3481 since Emacs no longer uses vfork on that platform.
3483 2012-09-17 Glenn Morris <rgm@gnu.org>
3485 * emacs.c: Use COPYRIGHT.
3487 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
3489 Remove configure's --without-sync-input option (Bug#12450).
3490 When auditing signal-handling in preparation for cleaning it up,
3491 I found that SYNC_INPUT has race conditions and would be a real
3492 pain to fix. Since it's an undocumented and deprecated
3493 configure-time option, now seems like a good time to remove it.
3494 Also see <http://bugs.gnu.org/11080#16>.
3495 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
3496 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
3497 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
3498 (malloc_hysteresis):
3499 (check_depth) [XMALLOC_OVERRUN_CHECK]:
3500 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
3501 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
3502 (dont_register_blocks, bytes_used_when_reconsidered)
3503 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
3504 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
3505 [!SYSTEM_MALLOC && !SYNC_INPUT]:
3506 Remove. All uses removed.
3507 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
3508 implementation, one that depends on whether the new macro
3509 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
3511 * atimer.c (run_timers, handle_alarm_signal):
3512 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
3513 (handle_async_input, process_pending_signals)
3514 (handle_input_available_signal, init_keyboard):
3515 * nsterm.m (ns_read_socket):
3516 * process.c (wait_reading_process_output):
3517 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
3518 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
3520 * xterm.c (XTread_socket):
3522 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
3523 * eval.c (handling_signal): Remove. All uses removed.
3524 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
3525 All uses replaced with the SYNC_INPUT version.
3526 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
3528 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
3531 * font.c (Ffont_shape_gstring): Remove unused local.
3533 2012-09-16 Glenn Morris <rgm@gnu.org>
3535 * Makefile.in (clean): No longer run nextstep's clean.
3537 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
3539 (ns-app): Move here from ns.mk, and simplify.
3540 (clean): Simplify nextstep entry.
3541 * ns.mk: Remove file.
3543 2012-09-17 Kenichi Handa <handa@gnu.org>
3545 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
3546 not covert the last few charactes.
3548 2012-09-16 Kenichi Handa <handa@gnu.org>
3550 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
3551 here, but just check the validity of glyphs in the glyph-string.
3553 2012-09-16 Martin Rudalics <rudalics@gmx.at>
3555 * window.c (Fwindow_parameter, Fset_window_parameter):
3556 Accept any window as argument (Bug#12452).
3558 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
3560 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
3561 to ns_term_init to avoid memory leak.
3563 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
3564 explicit retain/release.
3565 (ns_term_init): Only allow one display. Initialize outerpool and
3568 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
3570 Port _setjmp fix to POSIXish hosts as well as Microsoft.
3571 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
3572 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
3573 the Microsoft problem in a different way, by altering ../nt/config.nt.
3575 2012-09-15 Eli Zaretskii <eliz@gnu.org>
3590 * w16select.c: Remove inclusion of setjmp.h, as it is now included
3591 by lisp.h. This completes removal of setjmp.h inclusion
3592 erroneously announced in the previous commit. (Bug#12446)
3594 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
3597 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
3598 not defined as a macro. The latter happens on MS-Windows.
3601 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
3603 Port better to POSIX hosts lacking _setjmp (Bug#12446).
3604 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
3605 Some instances of '#include <setjmp.h>' removed, if the
3606 only reason for the instance was because "lisp.h" was included.
3607 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
3608 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
3609 and _longjmp with the new symbols. Emacs already uses _setjmp if
3610 available, so this change affects only POSIXish hosts that have
3611 sigsetjmp but not _setjmp, such as some versions of Solaris and
3612 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
3613 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
3614 (png_load_body) [HAVE_PNG]:
3615 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
3616 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
3617 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
3618 since PNG requires jmp_buf. This is the only exception to the
3619 general rule that we now use sys_setjmp and sys_longjmp.
3620 This exception is OK since this code does not change the signal
3621 mask or longjmp out of a signal handler.
3623 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
3625 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
3626 Include "syssignal.h", for 'main_thread'.
3628 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
3630 Avoid out-of-range marker position (Bug#12426).
3631 * insdel.c (replace_range, replace_range_2):
3632 Adjust markers before overlays, as suggested by comments.
3633 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
3634 Remove redundant check before calling offset_intervals.
3636 2012-09-14 Martin Rudalics <rudalics@gmx.at>
3638 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
3639 current buffer (Bug#12387).
3641 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
3643 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
3645 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
3647 Use a more backwards-compatible timer format (Bug#12430).
3648 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
3649 vector element, not from the 4th, since PSECS is now at the end.
3650 (Fcurrent_idle_time): Doc fix.
3652 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
3654 Function to mark objects and remove killed buffers at once.
3655 * alloc.c (discard_killed_buffers): Rename to ...
3656 (mark_discard_killed buffers) ... new name. Add marking
3657 of remaining objects. Fix comment. Adjust users.
3658 (mark_object): Do not touch frame buffer lists here.
3659 * frame.c (delete_frame): Reset frame buffer lists here.
3661 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
3663 Better workaround for GNOME bug when --enable-gcc-warnings.
3664 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
3665 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
3666 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
3668 Simplify SIGIO usage (Bug#12408).
3669 The code that dealt with SIGIO was crufty and confusing, e.g., it
3670 played tricks like "#undef SIGIO" but these tricks were not used
3671 consistently. Simplify mostly by not #undeffing standard symbols,
3672 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
3673 or not as we please) rather than "defined SIGIO" (standard symbol
3674 that we probably shouldn't #undef).
3675 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
3676 Modules that need it can include it.
3677 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
3678 * dispextern.h (ignore_sigio): New decl.
3679 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
3680 unconditionally, since it's now a no-op if !USABLE_SIGIO.
3681 * emacs.c (shut_down_emacs):
3682 * keyboard.c (kbd_buffer_store_event_hold):
3683 Use ignore_sigio rather than invoking 'signal' directly.
3684 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
3686 (FIONREAD, SIGIO): Do not #undef.
3687 (tty_read_avail_input): Use #error rather than a syntax error.
3688 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
3689 for I_PIPE, used by SETUP_SLAVE_PTY.
3690 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
3691 * sysdep.c (croak): Remove; no longer needed. This bit of
3692 temporary code, with Fred N. Fish's comment that it's temporary,
3693 has been in Emacs since at least 1992!
3694 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
3695 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
3696 * syssignal.h (croak): Remove decl.
3697 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
3698 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
3699 now that we're termios-only.
3700 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
3701 * term.c (dissociate_if_controlling_tty): Use #error rather than
3704 Work around GCC and GNOME bugs when --enable-gcc-warnings.
3705 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
3706 to work around GNOME bug 683906.
3707 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
3708 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
3709 This works around GCC bug 54561.
3711 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
3713 More fixes for 'volatile' and setjmp/longjmp.
3714 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
3715 * image.c (struct png_load_context) [HAVE_PNG]: New type.
3716 (png_load_body) [HAVE_PNG]:
3717 (jpeg_load_body) [HAVE_JPEG]:
3718 New function, with most of the old parent function's body.
3719 (png_load) [HAVE_PNG]:
3720 (jpeg_load) [HAVE_JPEG]:
3721 Invoke the new function, to avoid longjmp munging our locals.
3722 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
3723 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
3724 longjmp is passed 2, as the C standard doesn't guarantee this.
3725 Instead, store the failure code into mgr->failure_code.
3727 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
3729 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
3730 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
3731 (syms_of_keyboard): Remove support for unread-command-char.
3733 2012-09-12 Eli Zaretskii <eliz@gnu.org>
3735 * w32proc.c (sys_kill): If PID is our process ID and the signal is
3736 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
3737 violation. (Bug#12426)
3739 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
3741 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
3743 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
3745 * eval.c: Add `inhibit-debugger'.
3746 (Qinhibit_debugger): New symbol.
3747 (call_debugger): Bind it instead of Qdebug_on_error.
3748 (maybe_call_debugger): Test Vinhibit_debugger.
3749 (syms_of_eval): Define inhibit-debugger.
3750 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
3751 (syms_of_xdisp): Remove inhibit-debug-on-message.
3753 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
3755 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
3756 If a nonvolatile local variable is written before a _longjmp to
3757 the frame containing the variable, and is read after the _longjmp,
3758 the value read is indeterminate. Some local variables of type
3759 'struct handler' and 'struct catchtag' are used in this way, so
3760 mark each of their slots as volatile if the slot can be set before
3761 _longjmp and read afterwards.
3762 * lisp.h (struct handler): var and chosen_clause are now volatile.
3763 (struct catchtag): val, next, and pdlcount are now volatile.
3765 * bidi.c (bidi_push_it, bidi_pop_it):
3766 * fns.c (copy_hash_table):
3767 * image.c (define_image_type):
3768 * keyboard.c (kbd_buffer_store_event_hold):
3769 * process.c (Fprocess_send_eof):
3770 * xfaces.c (x_create_gc) [HAVE_NS]:
3771 * xgselect.c (xg_select):
3772 Prefer assignment to memcpy when either will do.
3774 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
3775 Use pointer-to-a-pointer to simplify and avoid a NILP check each
3776 time an item is removed. No need to mark this function 'inline';
3777 the compiler knows better than we do.
3779 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
3781 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
3782 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
3783 to change_frame_size (Bug#12388).
3784 (windowDidResize:): Pass YES to updateFrameSize.
3786 * nsterm.h: Add delay parameter to updateFrameSize.
3788 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
3790 Discard killed buffers from deleted window and frame objects.
3791 This reduces an amount of references to killed buffers and
3792 helps GC to reclaim them faster.
3793 * alloc.c (discard_killed_buffers): New function.
3794 (mark_object): Use it for deleted windows and frames.
3795 (mark_object): If symbol's value is set up for a killed buffer
3796 or deleted frame, restore its global binding.
3797 * data.c (swap_in_global_binding): Add GC notice.
3798 (swap_in_symval_forwarding): Use convenient set_blv_where.
3799 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
3800 * window.h: ... to here.
3802 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
3804 Convenient macro to check whether the buffer is live.
3805 * buffer.h (BUFFER_LIVE_P): New macro.
3806 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
3807 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
3809 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3811 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
3812 composition cases (Bug#12364).
3814 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
3815 overhang of succeeding glyphs overlapping box cursor.
3817 * w32term.c (x_draw_glyph_string): Likewise.
3819 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
3821 Simplify, document, and port floating-point (Bug#12381).
3822 The porting part of this patch fixes bugs on non-IEEE platforms
3823 with frexp, ldexp, logb.
3824 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
3826 * floatfns.c: Simplify discussion of functions that Emacs doesn't
3827 support, by removing commented-out code and briefly listing the
3828 C89 functions excluded. The commented-out stuff was confusing
3829 maintenance, e.g., we thought we needed cbrt but it was commented out.
3830 (logb): Remove decl; no longer needed.
3831 (isfinite): New macro, if not already supplied.
3832 (isnan): Don't replace any existing macro.
3833 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
3834 are present on all C89 platforms.
3835 (Ffrexp): Do not special-case zero, as frexp does the right thing
3837 (Flogb): Do not use logb, as it doesn't have the desired meaning
3838 on hosts that use non-base-2 floating point. Instead, stick with
3839 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
3840 frexp, to avoid getting an unspecified result.
3842 * xdisp.c (Qinhibit_debug_on_message): Now static.
3844 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
3846 * nsterm.m (ns_update_begin): Set clip path to whole view by using
3847 NSBezierPath (Bug#12131).
3849 2012-09-10 Chong Yidong <cyd@gnu.org>
3851 * fns.c (Fdelq, Fdelete): Doc fix.
3853 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
3855 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
3856 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
3858 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
3860 * lisp.h (make_lisp_ptr): New macro to replace XSET.
3861 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
3864 2012-09-09 Eli Zaretskii <eliz@gnu.org>
3866 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
3867 left fringe if the window has a left margin. This avoids leaving
3868 traces of the cursor because its leftmost pixel is not drawn over.
3870 * dispnew.c (update_window_line): When the left margin area of a
3871 screen line is updated, set the redraw_fringe_bitmaps_p flag of
3872 that screen line. (Bug#12277)
3874 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
3876 Assume C89 or later for math functions (Bug#12381).
3877 This simplifies the code, and makes it a bit smaller and faster,
3878 and (most important) makes it easier to clean up signal handling
3879 since we can stop worring about floating-point exceptions in
3880 library code. That was a problem before C89, but the problem
3881 went away many years ago on all practical Emacs targets.
3882 * data.c, image.c, lread.c, print.c:
3883 Don't include <math.h>; no longer needed.
3884 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
3885 might be autoconfigured, as that never happens.
3887 * doprnt.c (DBL_MAX_10_EXP):
3888 * print.c (DBL_DIG):
3889 Remove. C89 or later always defines these.
3890 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
3891 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
3892 (arith_error, domain_error, domain_error2):
3893 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
3894 no longer needed -- we simply return what C returns. All uses removed.
3895 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
3897 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
3898 Remove. All uses expanded, as these macros are no longer used
3899 more than once and are now more trouble than they're worth.
3900 (Ftan): Use tan, not sin / cos.
3901 (Flogb): Assume C89 frexp.
3902 (fmod_float): Assume C89 fmod.
3903 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
3904 (init_floatfns): Remove. All uses removed.
3906 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
3908 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
3909 compositeToPoint for OSX < 10.6 (Bug#12390).
3911 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
3913 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
3914 This produces more-accurate results.
3916 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
3918 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
3919 changes (Bug#12088).
3921 2012-09-08 Chong Yidong <cyd@gnu.org>
3923 * syntax.c (Fstring_to_syntax): Doc fix.
3925 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
3927 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
3928 in the internal border.
3929 (x_set_window_size): Remove static variables and their usage.
3930 (ns_redraw_scroll_bars): Fix NSTRACE arg.
3931 (ns_after_update_window_line, ns_draw_fringe_bitmap):
3932 Remove fringe/internal border adjustment (Bug#11052).
3933 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
3934 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
3935 (ns_fix_rect_ibw): Remove.
3936 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
3937 (ns_dumpglyphs_box_or_relief): Ditto.
3938 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
3940 (ns_dumpglyphs_image): Ditto.
3941 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
3943 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
3944 their usage. Add fringe_extended_p and its use as in other terms.
3945 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
3946 scroll bar was removed.
3947 (updateFrameSize): New function.
3948 (windowDidResize): Move code to updateFrameSize and call it.
3950 * nsterm.h (EmacsView): Add updateFrameSize.
3952 2012-09-07 Chong Yidong <cyd@gnu.org>
3954 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
3956 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
3958 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
3960 More signal-handler cleanup (Bug#12327).
3961 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
3962 Problem introduced when merging patches. Noted by Eli Zaretskii in
3963 <http://bugs.gnu.org/12327#67>.
3964 * floatfns.c: Comment fix.
3965 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
3966 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
3967 and anyway the declaration is harmless even if SIGDANGER is not defined.
3968 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
3969 defined BROKEN_FIONREAD). systty.h formerly did this, but other
3970 source files not surprisingly expected syssignal.h to define, or
3971 not define, SIGIO, and it's cleaner to do it that way, for consistency.
3972 Include <sys/ioctl.h>, for FIONREAD.
3973 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
3974 This eliminates a problem whereby other files mysteriously had
3975 to include "syssignal.h" before including "systty.h" if they
3976 wanted to use "#ifdef SIGIO".
3978 2012-09-07 Eli Zaretskii <eliz@gnu.org>
3980 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
3982 * w32.c (sigemptyset): Empty the set.
3983 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
3985 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
3987 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
3989 * alloc.c (mark_buffer): Revert unsafe marking optimization.
3990 (mark_object): Likewise for frame objects.
3992 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
3994 * syssignal.h (handle_on_main_thread): Always declare,
3995 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
3996 This ports to platforms without HAVE_PTHREAD.
3998 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
4000 Signal-handler cleanup (Bug#12327).
4001 Emacs's signal handlers were written in the old 4.2BSD style with
4002 sigblock and sigmask and so forth, and this led to some
4003 inefficiencies and confusion. Rewrite these to use
4004 pthread_sigmask etc. without copying signal sets around. Also,
4005 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
4006 'signal', and instead use functions that do not attempt to take
4007 over the system name space. This patch causes Emacs's text
4008 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
4009 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
4010 Do not include <signal.h> or "syssignal.h", as these
4011 modules do not use signals.
4012 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
4013 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
4014 Do not include <signal.h>, as "syssignal.h" does that for us now.
4015 * atimer.c (sigmask_atimers): New function.
4016 (block_atimers, unblock_atimers): New functions,
4017 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
4019 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
4020 no longer needed here.
4021 * emacs.c (main): Inspect existing signal handler with sigaction,
4022 so that there's no need to block and unblock SIGHUP.
4023 * sysdep.c (struct save_signal): New member 'action', replacing
4024 old member 'handler'.
4025 (save_signal_handlers, restore_signal_handlers):
4026 Use sigaction instead of 'signal' to save and restore.
4027 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
4028 New function. All users of 'signal' modified to use set_sighandler
4029 if they're writeonly, and to use sys_signal if they're read+write.
4030 (emacs_sigaction_init, forwarded_signal): New functions.
4031 (sys_signal): Remove. All uses replaced by calls to sigaction
4032 and emacs_sigaction_init, or by direct calls to 'signal'.
4033 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
4034 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
4035 all uses replaced by pthread_sigmask etc. calls.
4036 * syssignal.h: Include <signal.h>.
4037 (emacs_sigaction_init, forwarded_signal): New decls.
4038 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
4039 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
4040 (sigmask, sys_sigmask): Remove; no longer needed.
4041 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
4042 (sigblock, sigunblock, sigfree):
4043 (sigsetmask) [!defined sigsetmask]:
4044 Remove. All uses replaced by pthread_sigmask.
4045 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
4046 no longer need to be replaced, and its typical old uses
4047 are now done via emacs_sigaction_init and sigaction.
4048 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
4049 (sys_sigdel): Remove; unused.
4050 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
4052 2012-09-06 Eli Zaretskii <eliz@gnu.org>
4054 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
4055 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
4057 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
4059 Explicitly mark buffer_defaults and buffer_local_symbols.
4060 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
4061 mark_local_symbols here.
4062 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
4063 since special buffers aren't marked here any more.
4064 (allocate_buffer): Chain new buffer with all_buffers here...
4065 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
4067 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
4068 (syms_of_buffer): Remove staticpro of the above.
4069 (init_buffer_once): Set names for buffer_defaults and
4070 buffer_local_symbols.
4072 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
4074 Use bool for booleans in font-related modules.
4075 * font.c (font_intern_prop, font_style_to_value)
4076 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
4077 (generate_otf_features, font_check_otf_features, font_check_otf)
4078 (font_match_p, font_list_entities, font_at):
4079 * fontset.c (fontset_id_valid_p, reorder_font_vector
4080 (fontset_find_font, Fset_fontset_font)
4081 (face_suitable_for_char_p) [0]:
4082 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
4083 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
4084 (m17n_flt_initialized, ftfont_shape_by_flt):
4085 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
4086 * nsfont.m (nsfont_draw):
4087 * w32font.c (w32font_draw):
4088 * w32term.c (x_draw_glyphless_glyph_string_foreground):
4089 Use bool for booleans.
4090 * font.h: Adjust to above API changes.
4091 (struct font, struct font_driver, struct font_driver_list):
4092 Use bool for booleans.
4093 (struct font): Remove useless member encoding_type.
4095 * fontset.c, xftfont.c: Omit unnecessary static decls.
4097 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
4099 * alloc.c (mark_object): Revert window marking code
4100 since it's unsafe for the Fset_window_configuration.
4102 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
4104 Fix race conditions with signal handlers and errno (Bug#12327).
4105 Be more systematic about preserving errno whenever a signal
4106 handler returns, even if it's not in the main thread. Do this by
4107 renaming signal handlers to distinguish between signal delivery
4108 and signal handling. All uses changed.
4109 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
4110 * data.c (deliver_arith_signal): Rename from arith_error.
4111 * dispnew.c (deliver_window_change_signal): Rename from
4112 window_change_signal.
4113 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
4114 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
4115 * keyboard.c (deliver_input_available_signal): Rename from
4116 input_available_signal.
4117 (deliver_user_signal): Rename from handle_user_signal.
4118 (deliver_interrupt_signal): Rename from interrupt_signal.
4119 * process.c (deliver_pipe_signal): Rename from send_process_trap.
4120 (deliver_child_signal): Rename from sigchld_handler.
4121 * atimer.c (handle_alarm_signal):
4122 * data.c (handle_arith_signal):
4123 * dispnew.c (handle_window_change_signal):
4124 * emacs.c (handle_fatal_signal, handle_danger_signal):
4125 * keyboard.c (handle_input_available_signal):
4126 * keyboard.c (handle_user_signal, handle_interrupt_signal):
4127 * process.c (handle_pipe_signal, handle_child_signal):
4128 New functions, with the actual signal-handling code taken from the
4129 original respective signal handlers, sans the sporadic attempts to
4130 preserve errno, since that's now done by handle_on_main_thread.
4131 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
4132 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
4133 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4135 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4136 Move initialization of main_thread to sysdep.c's init_signals.
4137 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
4138 our usage, and simplifies the mainline code.
4139 (record_child_status_change): New static function, as a helper
4140 for handle_child_signal, and with most of the old child handler's
4142 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
4143 (handle_child_signal): Use the above.
4144 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4145 Moved here from emacs.c.
4146 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
4147 code moved here from emacs.c's main function.
4148 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
4149 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
4150 This lets callers save and restore errno properly.
4152 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4154 Remove redundant or unused things here and there.
4155 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
4156 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
4157 * editfns.c (Fcompare_buffer_substrings): Likewise.
4158 * frame.h (struct terminal, struct font_driver_list):
4159 Remove redundant declarations.
4160 * window.h (Qleft, Qright): Likewise.
4162 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4164 Do not mark objects from deleted buffers, windows and frames.
4165 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
4166 (mark_object): Likewise for windows and frames.
4168 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4170 * alloc.c (valid_lisp_object_p): Treat killed buffers,
4171 buffer_defaults and buffer_local_symbols as valid objects.
4172 Return special value to denote them.
4174 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
4176 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
4177 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
4178 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
4179 (file_name_absolute_p, Fsubstitute_in_file_name):
4180 (check_executable, check_writable, Ffile_accessible_directory_p)
4181 (Fset_file_selinux_context, Fdefault_file_modes)
4182 (Finsert_file_contents, choose_write_coding_system)
4183 (Fwrite_region, build_annotations, a_write, e_write)
4185 * filelock.c (boot_time_initialized, get_boot_time)
4186 (get_boot_time_1, lock_file_1, within_one_second):
4187 * floatfns.c (in_float):
4188 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
4189 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
4190 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
4191 * lisp.h (struct Lisp_Hash_Table.cmpfn):
4192 * window.c (compare_window_configurations):
4193 Use bool for booleans.
4194 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
4195 (Fdefault_file_modes): Now mode_t, not int, for modes.
4196 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
4197 (internal_delete_file): Now returns void, not a (boolean) int,
4198 since nobody was looking at the return value.
4199 * lisp.h, window.h: Adjust to above API changes.
4201 * xdisp.c (set_message): Simplify and reindent last change.
4203 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
4205 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
4207 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
4209 * eval.c (call_debugger): Make the function non-static so that we
4210 can call it from set_message.
4212 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
4213 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
4215 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
4217 Give more-useful info on a fatal error (Bug#12328).
4218 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
4219 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
4220 of doing the work ourselves.
4221 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
4222 do most of the work.
4223 (fatal_error_backtrace): New function, taken from the guts
4224 of the old fatal_error_signal, but with a new option to output
4226 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
4227 info about the signal than just its number.
4228 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
4229 * sysdep.c: Include <execinfo.h>
4230 (emacs_backtrace): New function, taken partly from the previous
4231 code of the 'die' function.
4232 (emacs_abort): Call fatal_error_backtrace rather than abort.
4234 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
4236 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
4237 eager (load-time) macro-expansion.
4238 * lisp.mk (lisp): Add macroexp.
4240 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
4242 Simplify redefinition of 'abort' (Bug#12316).
4243 Do not try to redefine the 'abort' function. Instead, redo
4244 the code so that it calls 'emacs_abort' rather than 'abort'.
4245 This removes the need for the NO_ABORT configure-time macro
4246 and makes it easier to change the abort code to do a backtrace.
4247 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
4248 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
4249 Remove; sysdep.c's emacs_abort now takes its place.
4250 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
4251 'abort' changed to use 'emacs_abort'.
4252 * msdos.c (dos_abort) [defined abort]: Remove; not used.
4253 (abort) [!defined abort]: Rename to ...
4254 (emacs_abort): ... new name.
4255 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
4256 the place of the old 'abort' in emacs.c.
4257 * w32.c, w32fns.c (abort): Do not #undef.
4258 * w32.c (emacs_abort): Rename from w32_abort.
4260 2012-09-04 Eli Zaretskii <eliz@gnu.org>
4262 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
4263 offsets[j].dv, since the y axis of the screen coordinates points
4264 down, while the y axis of the font definition coordinates points
4265 up. This fixes display of Arabic diacritics such as KASRA and
4266 KASRATAN. (Bug#11860)
4268 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
4270 Be more systematic about _setjmp vs setjmp.
4271 * alloc.c (test_setjmp, mark_stack):
4272 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
4273 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
4274 (png_load, my_error_exit, jpeg_load):
4275 * process.c (send_process_trap, send_process):
4276 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
4277 The underscored versions are up to 30x faster on some hosts.
4278 Formerly, the code used setjmp+longjmp sometimes and
4279 _setjmp+_longjmp at other times, with no particular reason to
4280 prefer setjmp+longjmp.
4282 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
4284 Fix minor problem found by static checking.
4285 * buffer.c (Fdelete_all_overlays): Return nil.
4287 2012-09-03 Martin Rudalics <rudalics@gmx.at>
4289 * buffer.c (Fdelete_all_overlays): New function.
4291 2012-09-03 Chong Yidong <cyd@gnu.org>
4293 * gtkutil.c: Add extern decl for Qxft.
4295 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
4297 * emacs.c, eval.c: Use bool for boolean.
4298 * emacs.c (initialized, inhibit_window_system, running_asynch_code):

4306 * process.c (read_process_output, exec_sentinel):
4307 Use bool for booleans.
4308 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
4309 All callers changed.
4310 * eval.c (interactive_p): Omit always-true boolean argument
4311 EXCLUDE_SUBRS_P. All callers changed.
4312 * dispextern.h, lisp.h: Reflect above API changes.
4313 * firstfile.c (dummy): Use the address of 'main', whose signature
4314 won't change, instead of the address of 'initialize', whose
4315 signature just changed from int to bool.
4316 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
4317 * msdos.c (fatal_error_in_progress): ... from here.
4318 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
4320 (redisplay_internal, unwind_redisplay): Simply clear
4321 REDISPLAYING_P when unwinding, instead of saving its previous,
4322 always-false value and then restoring it.
4324 Clean up some extern decls.
4325 Mostly, this hoists extern decls out of .c files and into .h files.
4326 That way, we're more likely to catch errors if the interfaces change.
4327 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
4328 declare xg_mark_data.
4329 * dispextern.h (x_frame_parm_handlers):
4331 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
4332 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
4333 (Qultra_bold, Qoblique, Qitalic):
4334 Move extern decl here from .c file.
4335 * alloc.c (xg_mark_data) [USE_GTK]:

4344 * process.c (QCfamily, QCfilter):
4345 * widget.c (free_frame_faces):
4346 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
4347 * xfont.c (x_clear_errors):
4348 * xterm.c (x_frame_parm_handlers):
4349 Remove now-redundant extern decls.
4350 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
4351 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
4353 * xfaces.c: Remove unnecessary static decls.
4354 * xterm.c (updating_frame): Remove decl of nonexistent object.
4356 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
4357 when building globals.h, as the objects that are not built on
4358 this host are not needed to compile C files on this host.
4360 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
4362 * gtkutil.h: Remove prototype for x_wm_set_size_hint.

4375 (format_time_string, general_insert_function)
4376 (make_buffer_string, make_buffer_string_both)
4377 (Fsubst_char_in_region, Ftranslate_region_internal, Fformat):
4378 * insdel.c (check_markers, gap_left, adjust_markers_for_insert)

4389 (set_intervals_multibyte_1, set_intervals_multibyte):
4390 * keyboard.c (decode_timer):
4391 Use bool for boolean.
4392 * intervals.h, lisp.h, systime.h: Reflect above API changes.
4393 * editfns.c (struct info): Use 1-bit unsigned bitfields for booleans.
4395 2012-09-02 Chong Yidong <cyd@gnu.org>
4397 * keymap.c (push_key_description): Print M-TAB as C-M-i
4400 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
4402 * makefile.w32-in (CCL_H, W32FONT_H): New macros.
4403 (ATIMER_H, FONT_H, $(BLD)/alloc.$(O), $(BLD)/callproc.$(O))

4408 ($(BLD)/w32font.$(O), $(BLD)/w32uniscribe.$(O)): Update dependencies.
4410 2012-09-01 Eli Zaretskii <eliz@gnu.org>
4412 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
4413 more than one grapheme cluster passed to the shaper: compute the
4414 offset adjustment values separately for each cluster. (Bug#11860)
4416 * image.c: Restore mistakenly removed inclusion of w32.h. Without
4417 it, GCC doesn't see prototypes of w32_delayed_load, and complains
4418 about implicit conversions from integer to pointer.
4420 2012-09-01 Daniel Colascione <dancol@dancol.org>
4422 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
4423 system used too early.
4425 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
4427 Better seed support for (random).

4445 window-system headers.
4447 * w32xfns.c (x_sync): Correct definition of x_sync (a no-op here)

4451 directly accessing frame internals.
4453 * w32font.h: Include font.h. Define syms_of_w32font and
4456 * process.c: Include TERM_HEADER instead of listing all possible
4457 window-system headers.
4459 * nsterm.h: Remove declarations now in frame.h.
4460 Define FRAME_X_SCREEN, FRAME_X_VISUAL.
4462 * menu.c: Include TERM_HEADER instead of listing all possible
4463 window-system headers.
4465 * keyboard.h: Declare ignore_mouse_drag_p whenever we have a
4468 * keyboard.c: Include TERM_HEADER instead of listing all possible
4469 window-system headers.
4471 * image.c: Include TERM_HEADER instead of listing all possible
4472 window-system headers. Declare Vlibrary_cache when compiling for
4475 * gtkutil.h (xg_list_node_): Include xterm.h to pick up needed
4476 window system declarations.
4478 * frame.h: Move common functions here: set_frame_menubar,
4479 x_set_window_size, x_sync, x_get_focus_frame,
4480 x_set_mouse_position, x_set_mouse_pixel_position,
4481 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,
4482 x_char_width, x_char_height, x_pixel_width, x_pixel_height,

4502 the current window system; include in list of objects to link into
4505 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
4507 Remove mark_ttys function and fix tty_display_info initialization.
4508 * lisp.h (mark_ttys): Remove prototype.
4509 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
4510 to mark_ttys because all possible values of 'top_frame' slot are
4511 the frames which are reachable from Vframe_list.
4512 * term.c (mark_ttys): Remove.
4513 (init_tty): Safely initialize 'top_frame' slot with Qnil.
4515 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
4517 Change struct frame bitfields from unsigned char to unsigned.
4518 * frame.h (struct frame): Change type of 'display_preempted',
4519 'visible', 'iconified', 'has_minibuffer', 'wants_modeline',
4520 'auto_raise', 'auto_lower', 'no_split', 'explicit_name',
4521 'window_sizes_changed', 'mouse_moved' and 'pointer_invisible'
4522 bitfields from unsigned char to unsigned.
4524 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
4526 Remove unused member of struct x_output and struct w32_output.

4530 2012-08-30 Jan Djärv <jan.h.d@swipnet.se>
4532 * gtkutil.c (x_wm_set_size_hint): Use 1 col for base_width so it
4533 does not become zero (Bug#12234).
4535 2012-08-30 Paul Eggert <eggert@cs.ucla.edu>
4537 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
4538 for GCC 4.7.1 x86-64.
4540 2012-08-30 Glenn Morris <rgm@gnu.org>
4542 * lread.c (init_lread): For out-of-tree builds, only add the
4543 source directory's site-lisp dir to the load-path if it exists,
4544 consistent with in-tree builds. (Bug#12302)
4546 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>
4548 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize
4549 button_values to NULL. Call setStykeMask so dialogs get a close button.
4550 (windowShouldClose:): Set window_closed.
4551 (dealloc): New member, free button_values.
4552 (process_dialog:): Make member function. Remove window argument,
4553 replace window with self. Count buttons and allocate and store values
4555 (addButton:value:row:): value is int with the name tag. Call setTag
4556 with tag. Remove return self, declare return value as void.
4557 (addString:row:): Remove return self, declare return value as void.
4558 (addSplit): Remove return self, declare return value as void.
4559 (clicked:): Remove return self, declare return value as void.
4560 Set dialog_return to button_values[seltag]. Code formatting change.
4561 (initFromContents:isQuestion:): Adjust call to process_dialog.
4562 Code formatting change.
4563 (timeout_handler:): Set timer_fired to YES.
4564 (runDialogAt:): Set timer_fired to NO.
4565 Handle click on close button as quit.
4567 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
4568 Add window_closed and button_values. Add void as return value for
4569 add(Button|String|Split). addButton takes int instead of Lisp_Object.
4570 Add process_dialog as new member.
4572 2012-08-28 Eli Zaretskii <eliz@gnu.org>
4574 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it
4575 is not one of the heaps we manage. (Bug#12242)
4577 2012-08-28 Glenn Morris <rgm@gnu.org>
4579 * eval.c (Fcalled_interactively_p): Doc fix. (Bug#11747)
4581 2012-08-28 Martin Rudalics <rudalics@gmx.at>
4583 * window.c (Fset_window_configuration): Remove handling of

4590 * buffer.c (Fset_buffer_major_mode): Signal an error
4591 if the buffer is dead.
4592 (Fother_buffer, other_buffer_safely): Remove redundant
4595 2012-08-28 Dmitry Antipov <dmantipov@yandex.ru>
4597 Always use set_buffer_if_live to restore original buffer at unwind.
4598 * buffer.h (record_unwind_current_buffer): New function.
4599 * bytecode.c, dispnew.c, editfns.c, fileio.c, fns.c, insdel.c:
4600 * keyboard.c, keymap.c, minibuf.c, print.c, process.c, textprop.c:
4601 * undo.c, window.c: Adjust users.
4602 * buffer.c (set_buffer_if_live): Fix comment.
4604 2012-08-28 Dmitry Antipov <dmantipov@yandex.ru>
4606 Fix usage of set_buffer_internal.
4607 * buffer.h (set_buffer_internal): Make it BUFFER_INLINE.
4608 * buffer.c (set_buffer_if_live): Use set_buffer_internal.
4609 * coding.c (decode_coding): Omit redundant test.
4610 * fileio.c (decide_coding_unwind): Likewise.
4611 * fns.c (secure_hash): Likewise.

4613 * keyboard.c (command_loop_1): Likewise.
4614 * print.c (PRINTFINISH): Likewise.
4615 * xdisp.c (run_window_scroll_functions): Use set_buffer_internal.
4617 2012-08-27 Paul Eggert <eggert@cs.ucla.edu>

4637 (clear_glyph_matrix_rows): Rename from enable_glyph_matrix_rows,
4638 and remove last int (actually boolean) argument, which was always 0.
4639 All callers changed.
4640 * dispextern.h, frame.h, lisp.h: Reflect above API changes.
4641 * dispextern.h (struct composition_it): Use bool for boolean.
4642 (struct glyph_matrix): Don't assume buffer sizes can fit in 'int'.
4643 (struct bidi_it): Use unsigned:1, not int, for boolean prev_was_pdf.
4644 * dired.c (file_name_completion):
4645 Use bool for boolean. (This was missed in an earlier change.)
4647 2012-08-27 Martin Rudalics <rudalics@gmx.at>
4649 * window.c (Fset_window_configuration): Revert first part of
4652 2012-08-27 Jan Djärv <jan.h.d@swipnet.se>
4654 * nsterm.h (NSPanel): New class variable dialog_return.
4656 * nsmenu.m (initWithContentRect:styleMask:backing:defer:):
4657 Initialize dialog_return.
4658 (windowShouldClose:): Use stop instead of stopModalWithCode.
4659 (clicked:): Ditto, and also set dialog_return (Bug#12258).
4660 (timeout_handler:): Use stop instead of abortModal. Send a dummy
4662 (runDialogAt:): Make ret Lisp_Object. Set it from dialog_return when

4706 * fileio.c (Finsert_file_contents):
4707 Use bool for booleans.
4708 * coding.h, lisp.h: Reflect above API changes.
4709 * coding.c: Remove unnecessary static function decls.
4710 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
4711 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
4712 not a boolean 'int', since callers never look at the return value.
4713 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
4714 * coding.h (decoding_buffer_size, encoding_buffer_size)
4715 (emacs_mule_string_char): Remove unused extern decls.
4716 (struct iso_2022_spec, struct coding_system):
4717 Use 'unsigned int : 1' for boolean fields, since there's more than one.
4718 (struct emacs_mule_spec): Remove unused field 'full_support'.
4719 All initializations removed.
4720 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
4722 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
4724 Fix spare memory change (Bug#12286).
4725 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
4726 (valid_lisp_object_p): Likewise.
4728 2012-08-27 Martin Rudalics <rudalics@gmx.at>
4730 * window.c (Fset_window_configuration): Record any window's old
4731 buffer if it's replaced (see Bug#8789). If the new current
4732 buffer doesn't appear in the selected window, go to its old
4735 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
4737 Special MEM_TYPE_SPARE to denote reserved memory.
4738 * alloc.c (enum mem_type): New memory type.
4739 (refill_memory_reserve): Use new type for spare memory.
4740 This prevents live_cons_p and live_string_p from incorrect
4741 detection of uninitialized objects from spare memory as live.
4743 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
4746 * Makefile.in (.PHONY): versioclean -> versionclean.
4748 Remove unused external symbols.
4749 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
4750 * window.c (Qwindow_valid_p, decode_valid_window):
4751 Now static, not extern.
4752 * data.c (Qinterval): Remove; unused.
4753 (syms_of_data): Do not define 'interval'.
4754 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
4755 * window.h (decode_valid_window):
4758 * character.c, charset.c, chartab.c: Use bool for booleans.

4768 (char_table_set_range, optimize_sub_char_table)
4769 (map_sub_char_table):
4770 Use bool for boolean.
4771 * character.c (str_to_unibyte): Omit last boolean argument; it was
4772 always 0. All callers changed.
4773 * character.h, charset.h: Adjust to match previous changes.
4774 * character.h (char_printable_p): Remove decl of nonexistent function.
4775 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
4776 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
4777 are all boolean, so make them single-bit bitfields.
4779 * lisp.h (ASET): Remove attempt to detect side effects.
4780 It was meant to be temporary and it often doesn't work,
4781 because when IDX has side effects the behavior of IDX==IDX
4782 is undefined. See Stefan Monnier in
4783 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
4785 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
4787 * lisp.h (functionp): New function (extracted from Ffunctionp).
4788 (FUNCTIONP): Use it.
4789 * eval.c (Ffunctionp): Use it.
4791 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
4793 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
4794 as that's faster and simpler than static storage. Don't bother
4795 with the g_main_context_query overhead if g_main_context_pending
4796 says no events are pending.
4797 (gfds, gfds_size): Remove these static vars.
4798 (xgselect_initialize): Remove; no longer needed.
4799 All uses and decls removed.
4801 * emacs.c (fatal_error_signal_hook): Remove.
4802 All uses removed. This leftover from old code was always 0.
4804 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
4805 * casefiddle.c (casify_object, casify_region):
4806 * casetab.c (set_case_table):
4807 * category.c, category.h (word_boundary_p):
4808 * category.h (CHAR_HAS_CATEGORY):
4809 Use bool for booleans, instead of int.
4811 2012-08-25 Eli Zaretskii <eliz@gnu.org>
4813 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
4815 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
4817 On assertion failure, print backtrace if available.
4818 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
4819 (die) [ENABLE_CHECKING]: Print a backtrace if available.
4820 * Makefile.in (LIB_EXECINFO): New macro.
4823 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
4824 * bytecode.c (exec_byte_code):
4825 * callint.c (check_mark, Fcall_interactively):
4826 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
4827 (getenv_internal, sync_process_alive, call_process_exited):
4828 * lisp.h (USE_SAFE_ALLOCA):
4829 Use bool for booleans, instead of int.
4830 * lisp.h, process.h: Adjust prototypes to match above changes.
4831 * callint.c (Fcall_interactively): Don't assume the mark's
4832 offset fits in 'int'.
4834 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
4836 * buffer.c, buffer.h: Use bool for boolean.
4837 * buffer.c (reset_buffer_local_variables)

4843 (mmap_enlarge, mmap_set_vars):
4844 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
4845 Use bool for booleans, instead of int.
4846 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
4847 since the 1-or-0 return value is always ignored anyway.
4848 (mmap_initialized_p):
4849 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
4850 * buffer.h, lisp.h: Adjust prototypes to match above changes.
4852 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
4854 * bidi.c: Use bool for boolean.
4855 This is a bit more readable, and makes the text segment of bidi.o
4856 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
4857 Presumably it's faster too.
4858 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
4860 (bidi_cache_find_level_change, bidi_cache_iterator_state)
4861 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
4862 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
4863 (bidi_explicit_dir_char, bidi_level_of_next_char)
4864 (bidi_find_other_level_edge, bidi_move_to_visually_next):
4865 Use bool for booleans, instead of int.
4866 * dispextern.h (bidi_init_it, bidi_paragraph_init)
4867 (bidi_unshelve_cache): Adjust decls to match code.
4869 2012-08-23 Martin Rudalics <rudalics@gmx.at>
4871 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
4874 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
4876 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
4877 * atimer.h: Include <stdbool.h>.
4879 2012-08-22 Dan Nicolaescu <dann@gnu.org>
4881 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
4882 compile time tests instead of run time tests on systems that do
4884 (FRAME_MAC_P): Remove leftover from deleted code.
4885 * frame.c (syms_of_frame): Remove leftover from deleted code.
4887 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
4889 * nsterm.m (insertText:): Don't clear modifiers if code is space.
4891 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
4893 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
4894 Otherwise, the compiler complains about (A?B:C) where B is void
4895 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
4896 (fontset_add): Return void, for FONTSET_ADD.
4898 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
4900 * alloc.c: Use bool for booleans.
4901 (gc_in_progress, abort_on_gc)
4902 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
4903 (dont_register_blocks) [GC_MALLOC_CHECK]:
4904 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
4905 (check_string_bytes, make_specified_string, memory_full)
4906 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
4907 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
4908 (mark_stack, valid_pointer_p, make_pure_string)
4909 (Fgarbage_collect, survives_gc_p, gc_sweep):
4910 Use bool for booleans, instead of int.
4911 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
4912 Remove unused local.
4913 * alloc.c (PURE_POINTER_P):
4914 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
4915 * editfns.c (Fformat):
4916 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
4918 * fns.c (sweep_weak_table):
4919 * lisp.h (suppress_checking, push_message, survives_gc_p)
4920 (make_pure_string, gc_in_progress, abort_on_gc):
4921 * lread.c (readchar, read1):
4922 * print.c (Fprin1_to_string):
4923 * xdisp.c (push_message):
4924 Use bool for booleans affected directly or indirectly by
4927 Make recently-introduced setters macros.
4928 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
4929 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
4930 (set_fontset_default, set_fontset_fallback): Rename from their
4931 upper-case counterparts, and make them functions rather than macros.
4932 This is more consistent with the other recently-introduced setters.
4933 These don't need to be inline, since they're local.
4935 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
4937 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
4938 the loop (Bug#12247).
4940 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
4942 * lisp.h (vcopy): Use memcpy rather than our own loop.
4943 This fixes a performance regression introduced by the recent
4944 addition of vcopy. This means 'vcopy' will need to be modified
4945 for a copying collector, but that's OK. Also, tighten the
4946 checking in the assertion.
4948 2012-08-21 Eli Zaretskii <eliz@gnu.org>
4950 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
4951 components for RTL text (Bug#11860). Adjust X-OFFSET of each
4952 non-base glyph for the width of the base character, according to
4953 what x_draw_composite_glyph_string_foreground expects.
4954 Generate WADJUST value according to composition_gstring_width's
4955 expectations, to produce correct width of the composed character.
4956 Reverse the sign of the DU offset produced by ScriptPlace.
4958 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
4960 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
4962 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
4964 Avoid direct writes to contents member of struct Lisp_Vector.
4965 * lisp.h (vcopy): New function to copy data into vector.
4966 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
4967 * fns.c (Ffillarray): Use ASET.
4968 * keyboard.c (timer_check_2): Use AREF and ASET.
4969 (append_tool_bar_item, Frecent_keys): Use vcopy.
4970 * lread.c (read_vector): Use ASET.
4971 * msdos.c (Frecent_doskeys): Use vcopy.
4972 * xface.c (Finternal_copy_lisp_face): Use vcopy.
4973 (Finternal_merge_in_global_face): Use ASET and vcopy.
4974 * xfont.c (xfont_list_pattern): Likewise.
4976 2012-08-21 Martin Rudalics <rudalics@gmx.at>
4978 * window.c (Fwindow_point): For the selected window always return
4979 the position of its buffer's point.
4980 (Fset_window_point): For the selected window always go in its
4981 buffer to the specified position.
4983 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
4985 Setter macros for fontsets.
4986 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
4987 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
4988 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
4991 2012-08-20 Glenn Morris <rgm@gnu.org>
4993 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
4994 Don't assume that `ln -f' works.
4996 2012-08-20 Eli Zaretskii <eliz@gnu.org>
4998 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
4999 and later about non-assignments with no effect. See discussion at

5024 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
5025 (set_hash_hash, set_hash_index): Rename with _slot suffix.

5042 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
5044 Rely on <config.h> + <unistd.h> to declare 'environ',
5045 as gnulib does this if the system doesn't.
5046 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
5047 Remove declaration. MS-Windows declares it on stdlib.h which is

5081 * chartab.c, lisp.h (char_table_set, char_table_set_range):
5082 Return void, not Lisp_Object. Otherwise, the compiler
5083 complains about (A?B:C) where B is void and C is Lisp_Object
5084 when compiling CHAR_TABLE_SET, due to the recent change to
5085 the API of sub_char_table_set_contents.

5915 2012-08-04 Eli Zaretskii <eliz@gnu.org>
5917 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
5918 * w32.c (init_environment): Change the default values of many
5919 environment variables in dflt_envvars[] to NULL, to avoid pushing
5920 them into environment when they were not already defined.
5921 Remove the code that deletes site-lisp subdirectories from the default
5922 value of EMACSLOADPATH, as it is no longer needed.
5923 (check_windows_init_file): Now external, not static.
5924 Use Vload_path as is, without adding anything, as this function is now
5925 called when Vload_path is already set up.
5927 * w32.h (check_windows_init_file): Add prototype.
5929 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build
5930 directory, ignore the /*/i386/ tail in Vinvocation_directory, for
5931 compatibility with Posix platforms.
5932 (main): Move the call to check_windows_init_file to here from
5934 (decode_env_path) [WINDOWSNT]: Expand the %emacs_dir%/ prefix, if
5935 any, in the DEFALT argument into the root of the Emacs build or
5936 installation tree, as appropriate.
5938 * callproc.c (init_callproc_1): Call decode_env_path instead of
5939 doing its equivalent by hand.
5940 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
5941 the code that sets Vexec_path run on MS-Windows.
5943 * lread.c (init_lread): Add comments to #ifdef's.
5945 * msdos.c (dos_set_window_size, IT_update_begin)
5946 (IT_frame_up_to_date, IT_set_frame_parameters): Use FVAR and WVAR
5947 instead of direct references.

5953 Now constants, not macros.
5955 2012-08-03 Paul Eggert <eggert@cs.ucla.edu>
5957 Remove unnecessary casts involving pointers.
5958 These casts are no longer needed now that we assume C89 or later,
5959 since they involve casting to or from void *.
5960 * alloc.c (make_pure_string, make_pure_c_string, pure_cons)
5961 (make_pure_float, make_pure_vector):
5962 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP):

5971 (x_get_window_property, x_get_window_property_as_lisp_data):
5972 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
5973 Remove unnecessary pointer casts.
5974 * alloc.c (record_xmalloc): New function.
5975 * lisp.h (record_xmalloc): New decl.
5976 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
5977 more like a function. This is because the pointer cast is not
5978 needed. All uses changed.
5979 * print.c (print_string, print_error_message): Avoid length recalc.
5981 Improve fix for macroexp crash with debugging (Bug#12118).
5982 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
5983 ARRAY_MARK_FLAG when checking subscripts, because ASET is
5984 not supposed to be invoked from the garbage collector.
5985 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
5986 (gc_aset): New function, which is like ASET but can be
5987 used in the garbage collector.
5988 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)

5998 <g_b_init_create_symbolic_link>: New static flags.
5999 (globals_of_w32): Initialize them to zero.
6000 (GetSecurityInfo_Proc, CreateSymbolicLink_Proc): New typedefs.
6001 (map_w32_filename): Improve commentary. Simplify switch.
6002 (SYMBOLIC_LINK_FLAG_DIRECTORY): Define if not defined in system
6003 headers (most versions of MinGW w32api don't).
6004 (get_security_info, create_symbolic_link)
6005 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
6007 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
6008 in the argument file name.

6011 (sys_rename): Diagnose renaming of a symlink when the user doesn't
6012 have the required privileges.
6013 (get_file_security_desc_by_name): Rename from
6014 get_file_security_desc.
6015 (stat_worker): New function, with most of the guts of 'stat', and
6016 with addition of handling of symlinks and support for 'lstat'.
6017 If possible, get file's attributes and security information by
6018 handle, not by name. Produce S_IFLNK bit for symlinks, when
6019 called from 'lstat'.
6020 (stat, lstat): New functions, call 'stat_worker'.
6021 (symlink, readlink, careadlinkat): Rewritten to create and resolve
6022 symlinks when the underlying filesystem supports them.
6024 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
6026 Fix macroexp crash on Windows with debugging (Bug#12118).
6027 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
6028 checking subscripts; problem introduced with the recent
6029 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
6030 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
6031 since it's used in non-static inline functions now.
6033 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
6034 Don't assume buffer size fits in 'int'. Remove unused local.
6036 Use C99-style 'extern inline' if available.

6051 * category.c (CATEGORY_INLINE):
6052 * character.c (CHARACTER_INLINE):
6053 * charset.c (CHARSET_INLINE):
6054 * composite.c (COMPOSITE_INLINE):
6055 * dispnew.c (DISPEXTERN_INLINE):
6056 * sysdep.c (SYSTIME_INLINE):
6057 Define to EXTERN_INLINE, so that the corresponding functions
6058 are compiled into code.
6059 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
6060 (INLINE_HEADER_END): New macros.
6061 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

6081 hard-coding the path separator.
6083 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
6085 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
6086 This how ASET and AREF are supposed to work, and makes
6087 it easier to think about future improvements. See
6088 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
6089 * charset.h (set_charset_attr): New function.

6342 * s/aix4-2.h (sigmask): No need to undefine it, since syssignal.h
6343 does that unconditionally. Remove file, which is now empty.
6345 * s/freebsd.h, s/gnu-linux.h, s/sol2-6.h, s/unixware.h:
6348 2012-07-30 Paul Eggert <eggert@cs.ucla.edu>

6363 (CHAR_TABLE_STANDARD_SLOTS, CHAR_TABLE_EXTRA_SLOTS):
6364 Move to after the definition of struct Lisp_Char_Table,
6365 since the former now needs that type defined.

6466 * w32inevt.c: Include w32inevt.h.
6467 (w32_read_console_input): New inline function, calls either
6468 ReadConsoleInputA or ReadConsoleInputW, depending on the value of
6469 w32_console_unicode_input.
6470 (fill_queue): Call w32_read_console_input instead of ReadConsoleInput.
6471 (w32_kbd_patch_key, key_event): Use the codepage returned by
6472 GetConsoleCP, rather than the ANSI codepage returned by GetLocaleInfo.
6473 (key_event): use uChar.UnicodeChar only if
6474 w32_console_unicode_input is non-zero.

6504 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
6505 enumeration constants, as PURE and HEAP are too general, and clash
6506 with other headers and sources, such as gmalloc.c and the
6507 MS-Windows system headers. All users changed.
6509 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
6511 Revert last save_excursion_save and save_excursion_restore changes.
6512 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

6522 2012-07-27 Paul Eggert <eggert@cs.ucla.edu>
6524 Improve GDB symbol export (Bug#12036).
6525 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
6526 arms of an 'if', not using conditional expressions; otherwise GDB
6527 complains about the types in the unevaluated arm when the argument
6528 is an integer literal.
6529 (xgetint): Simplify expression.
6530 * alloc.c (gdb_make_enums_visible): New constant. This ports to
6531 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
6532 Zaretskii in <http://bugs.gnu.org/12036#13>.
6533 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
6534 needed now that we have gdb_make_enums_visible.
6535 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
6536 (enum enum_USE_LSB_TAG):
6537 New enum types, packaging up enums that need to be exported to GDB.

6556 * xfns.c (syms_of_xfns): Likewise.
6558 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
6560 Fast save_excursion_save and save_excursion_restore.
6561 * lisp.h (struct Lisp_Excursion): New data type.
6562 (PVEC_EXCURSION): New pseudovector type.
6563 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
6564 to deal with it. Adjust comments.

6575 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
6577 Fix export of symbols to GDB (Bug#12036).
6578 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
6579 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
6580 emacs.c, as this is a more-suitable home. Had this been done earlier
6581 the fix for 12036 would have avoided some of the problems noted in
6582 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
6583 would have been more obvious.
6584 * emacs.c: Do not include <verify.h>; no longer needed.
6585 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
6586 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
6587 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):

6592 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
6593 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
6594 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
6595 not be usable in #if. This simplifies things.
6597 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
6599 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
6601 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
6603 Simplify export of symbols to GDB (Bug#12036).
6604 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
6605 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
6606 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
6607 Adjust to changes in lisp.h and emacs.c, by using
6608 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
6609 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
6610 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
6611 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
6612 instead of gdb_valbits.
6613 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
6614 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
6615 instead of gdb_array_mark_flag.
6616 (xboolvector): Get size from $->size, not $->header.size.
6617 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
6618 (xreload, hook-run, hookpost-run): Remove.
6619 * emacs.c: Include <verify.h>.
6620 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
6621 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
6623 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
6624 (gdb_USE_LSB_TAG): New enum constants.
6625 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
6626 Also define these as enum constants, so they're visible to GDB.
6627 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
6628 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
6629 as constants, so they're visible to GDB.
6630 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
6631 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
6632 Now enum constants, not macros, so they're visible to GDB.
6633 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
6634 more convenient now. All uses changed.
6635 (VALMASK) [USE_LSB_TAG]: Also define in this case.
6636 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
6638 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>
6640 Explicitly free restriction data that are not needed anymore.

6643 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
6645 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
6646 add argument, tune behavior, and adjust all callers.
6648 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
6650 Use typedef for EMACS_INT, EMACS_UINT.
6651 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
6652 than macros. This simplifies debugging in the usual case, since
6653 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
6654 and it allows expressions involving EMACS_INT casts.
6655 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
6657 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

6667 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
6669 Adjust buffer text indirection counters at the end of Fkill_buffer.
6670 * buffer.c (Fkill_buffer): Adjust indirection counters when the
6671 buffer is definitely dead. This should really fix an issue reported
6672 by Christoph Scholtes again. (Bug#12007).
6673 (init_buffer_once): Initialize indirection counters of
6674 buffer_defaults and buffer_local_symbols (for sanity and safety).
6676 2012-07-24 Eli Zaretskii <eliz@gnu.org>
6678 * xdisp.c (init_iterator): Don't compute dimensions of truncation
6679 and continuation glyphs on tooltip frames, leave them at zero.
6680 Avoids continued lines in tooltips. (Bug#11832)
6682 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
6684 Simplify copy_overlay.
6685 * buffer.c (copy_overlay): Simplify. Use build_marker.

6691 or invalid. (Bug#12025)
6693 * window.c (decode_any_window): Disable CHECK_LIVE_FRAME test, as
6694 it signals an error when a tooltip frame is being created.
6696 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
6698 Cleanup miscellaneous objects allocation and initialization.
6699 * alloc.c (allocate_misc): Change to static. Add argument to
6700 specify the subtype. Adjust comment and users.
6701 (build_overlay): New function.
6702 * buffer.c (copy_overlays, Fmake_overlay): Use it.
6703 * lisp.h (struct Lisp_Overlay): Remove obsolete comment.
6704 (allocate_misc): Remove prototype.
6705 (build_overlay): Add prototype.
6707 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
6709 Swap buffer text indirection counters in Fbuffer_swap_text.
6710 * buffer.c (Fbuffer_swap_text): Swap indirections too.
6711 This avoids crash reported by Christoph Scholtes at
6712 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
6714 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
6716 * nsmenu.m (Popdown_data): New struct.
6717 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
6719 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
6720 (initWithContentRect): Make imgView and contentView non-static
6721 and autorelease them. Also autorelease img and matrix (Bug#12005).
6722 (dealloc): Remove (Bug#12005).
6724 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
6726 Adjust consing_since_gc when objects are explicitly freed.
6727 * alloc.c (GC_DEFAULT_THRESHOLD): New macro.
6728 (Fgarbage_collect): Use it. Change minimum to 1/10 of default.
6729 (free_cons, free_misc): Subtract object size from consing_since_gc.
6731 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>

6735 (live_buffer, set_marker_internal): New function.
6736 (Fset_marker, set_marker_restricted): Use set_marker_internal.
6737 (set_marker_both, set_marker_restricted_both): Use live_buffer.
6739 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
6741 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
6742 as it's limited by the amount of memory, not by INT_MAX.
6744 2012-07-21 Eli Zaretskii <eliz@gnu.org>
6746 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
6747 in special-event-map. See the discussion at
6748 http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00417.html
6751 * w32menu.c (add_menu_item): Cast to ULONG_PTR when assigning

7470 * s/aix4-2.h (unix): Remove; no longer needed.
7472 EMACS_TIME simplification (Bug#11875).
7473 This replaces macros (which typically do not work in GDB)

7475 The functional style also makes code easier to read and maintain.
7476 * systime.h: Include <sys/time.h> on all hosts, not just if
7477 WINDOWSNT, since 'struct timeval' is needed in general.

7518 Prefer snprintf to strncpy.
7519 * nsterm.m (ns_term_init):
7520 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
7521 * nsterm.m (ns_term_init):
7522 Avoid the need for strncpy, by using build_string or
7523 make_unibyte_string directly. Use dtoastr, not snprintf.
7524 * process.c (Fmake_network_process): Diagnose service names that
7525 are too long, rather than silently truncating them or creating
7526 non-null-terminated names.

7543 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
7544 where argument type is known to be a Lisp_Cons.

7599 O_RDONLY already includes it).
7601 Stop ns builds setting the EMACSLOADPATH environment variable.
7602 * nsterm.m (ns_load_path): Rename from ns_init_paths.
7603 Now it does not set EMACSLOADPATH, just returns the load-path string.
7604 * nsterm.h: Update accordingly.
7605 * lread.c [HAVE_NS]: Include nsterm.h.
7606 (init_lread) [HAVE_NS]: Use ns_load_path.

7616 (ns_init_paths): Do not set EMACSPATH.

7670 * nsterm.h (ns_etc_directory): Add it.
7671 * callproc.c [HAVE_NS]: Include nsterm.h.
7672 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
7674 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
7676 Move marker debugging code under MARKER_DEBUG.
7677 * marker.c (MARKER_DEBUG): Move marker debugging code under
7678 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
7679 for bootstrap with --enable-checking (~3x slowdown reported
7680 by Juanma Barranquero <lekktu@gmail.com>).
7681 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
7683 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
7685 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
7686 See <http://bugs.gnu.org/11825#29>.
7688 2012-07-08 Eli Zaretskii <eliz@gnu.org>
7690 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
7691 has no font, use the frame's font. (Bug#11813)
7692 (display_line): Add commentary about displaying truncation glyphs
7694 (produce_special_glyphs): Move here from term.c.
7696 * term.c (produce_special_glyphs): Move to xdisp.c.
7698 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
7701 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
7703 * xdisp.c (display_line): Avoid warning about implicit declaration
7706 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
7708 * lisp.h: Remove empty conditional.
7710 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
7712 * lread.c (load_path_check): Now static.
7714 Fix some minor --with-ns problems found by static checking.
7715 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
7716 (x_set_font) [!HAVE_X_WINDOWS]:
7717 * image.c (xpm_load_image) [HAVE_NS]:
7718 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
7719 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
7720 Remove unused local.
7721 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
7722 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
7723 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
7724 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
7725 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):

7727 Fix pointer signedness problem.
7728 * xfaces.c (FRAME_X_FONT_TABLE):
7729 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
7731 2012-07-07 Glenn Morris <rgm@gnu.org>
7733 * lread.c (load_path_check): New function, split from init_lread.
7734 (init_lread): Reorganize. Motivation:
7735 If EMACSLOADPATH is set, check/warn about that rather than the
7736 defaults, which we are not going to use. Hence we can remove
7737 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
7738 Don't warn if site-lisp directories are missing.
7739 If not installed, start from a blank load-path, since
7740 PATH_LOADSEARCH refers to the eventual installation directories.
7742 2012-07-07 Eli Zaretskii <eliz@gnu.org>
7744 Support truncation and continuation glyphs on GUI frames, when
7745 fringes are disabled. (Bug#11832)
7746 * xdisp.c (init_iterator): Get dimensions of truncation and
7747 continuation glyphs even if on GUI frames.
7748 Adjust it->last_visible_x on GUI frames when the left or right fringes,
7749 or both, are absent.
7750 (start_display, move_it_in_display_line_to): Handle the case of a
7751 GUI frame without a fringe to display continuation or truncation
7753 (insert_left_trunc_glyphs): Support GUI frames: make sure
7754 truncation glyphs overwrite enough glyphs from the current line to
7755 have sufficient space in pixels.
7756 (display_line): Support truncation and continuation glyphs on GUI
7757 frames. If some spare pixels are left on the line after inserting
7758 the truncation glyphs, fill that space with a stretch glyph of a
7759 suitably computed width.
7761 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
7762 produce_glyphs, to support GUI sessions.
7764 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
7766 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
7768 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
7770 Do not require float-time's arg to fit in time_t (Bug#11825).
7771 This works better on hosts where time_t is unsigned, and where
7772 float-time is applied to the (negative) difference between two times.
7773 * editfns.c (decode_time_components): Last arg is now double *,
7774 not int *, and means to store all the result as a double, without
7775 worrying about whether the seconds part fits in time_t.
7776 All callers changed.
7777 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
7778 All callers changed.
7779 (Ffloat_time): Do not fail merely because the specified time falls
7780 outside of time_t range.
7782 2012-07-07 Glenn Morris <rgm@gnu.org>
7784 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

7790 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
7791 Update dependencies.
7793 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
7795 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
7797 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).

7799 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
7800 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
7801 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
7802 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
7804 * xfont.c (compare_font_names): Redo to omit the need for casts.
7806 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
7808 * xfns.c (Fx_change_window_property): Doc fix.
7809 * w32fns.c (Fx_change_window_property): Doc fix.
7811 * w32fns.c (Fx_window_property): Accept the same arguments as the
7812 X Windows version. Doc fix.
7813 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
7815 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
7816 Eli Zaretskii <eliz@gnu.org>
7818 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
7819 Windows-specific code from nt/config.nt moved here.
7820 Obsolete settings removed.
7822 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
7824 * process.c: Avoid unnecessary calls to gettime.
7825 (wait_reading_process_output): Don't get the time of day
7826 when gobbling data immediately and not waiting, as there's no need
7827 for it in that case. This removes a FIXME.
7829 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
7831 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
7832 is defined (Bug#11768).
7834 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
7836 Fix marker debugging code.
7837 * marker.c (byte_char_debug_check): Do not perform the check
7838 if buffer is not multibyte.
7839 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
7840 Call byte_char_debug_check with correct arguments.
7842 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
7844 Compile marker debugging code only if ENABLE_CHECKING is defined.
7845 * marker.c (byte_char_debug_check, count_markers):
7846 Use only if ENABLE_CHECKING is defined.
7847 (byte_debug_flag): Remove.
7848 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
7849 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
7851 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
7853 Avoid code repetition in marker-related functions.
7854 * marker.c (attach_marker): New function.
7855 (Fset_marker, set_marker_restricted, set_marker_both)
7856 (set_marker_restricted_both): Use it.
7857 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
7858 Consistently rename charno to charpos.
7859 (marker_position): Add eassert.
7860 (marker_byte_position): Convert to eassert.

7872 * lisp.h (build_marker): New prototype.
7873 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
7874 * composite.c (autocmp_chars): Likewise.
7875 * editfns.c (buildmark): Remove.
7876 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
7877 (save_restriction_save): Use build_marker.
7878 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
7879 * window.c (save_window_save): Likewise.
7881 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
7883 Do not use Fdelete_overlay in delete_all_overlays
7884 to avoid redundant calls to unchain_overlay.
7885 * buffer.c (drop_overlay): New function.
7886 (delete_all_overlays, Fdelete_overlay): Use it.
7887 * minibuf.c (get_minibuffer): Fix comment.
7889 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
7891 Port to OpenBSD 5.1 amd64.
7892 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
7893 This is needed for OpenBSD, and should be harmless on all BSD systems.
7894 Also, include <sys/sysctl.h>, as it should be available on all
7895 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
7896 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
7897 use p_pid member, not kp_proc.pid.
7899 2012-07-06 Glenn Morris <rgm@gnu.org>
7901 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
7903 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
7905 More xmalloc and related cleanup.
7906 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
7907 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:

7912 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:
7913 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
7914 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
7916 Omit needless casts involving void * pointers and allocation.
7917 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
7918 as the former is more robust if P's type is changed.
7919 Prefer xzalloc to xmalloc + memset 0.
7920 Simplify malloc-or-realloc to realloc.
7921 Don't worry about xmalloc returning a null pointer.
7922 Prefer xstrdup to xmalloc + strcpy.
7923 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
7925 * keyboard.c (apply_modifiers_uncached): Prefer local array to
7926 alloca of a constant.
7928 2012-07-05 Eli Zaretskii <eliz@gnu.org>
7930 * xdisp.c (display_line): Fix horizontal pixel coordinates when
7931 hscroll is larger than the line width. Fixes long and futile
7932 looping inside extend_face_to_end_of_line (on a TTY) producing
7933 glyphs that are not needed and thrown away.
7935 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
7937 * marker.c (set_marker_restricted_both): Simplify by using
7940 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
7942 * editfns.c (region_limit): Simplify by using clip_to_bounds.
7944 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>

7949 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
7950 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
7951 followed by gtk_box_set_homogeneous (Bug#11768).
7952 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
7953 (update_theme_scrollbar_width, xg_create_scroll_bar):
7954 Use gtk_scrollbar_new (Bug#11768).
7955 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
7956 (is_box_type): New function (Bug#11768).
7957 (xg_tool_item_stale_p): Call is_box_type.
7958 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
7959 with default display (Bug#11768).
7961 2012-07-05 Eli Zaretskii <eliz@gnu.org>
7963 * xdisp.c (window_hscroll_limited): New function.
7964 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
7965 coordinates when window's hscroll is set to insanely large
7968 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
7970 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
7971 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
7973 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
7976 * lisp.h (xzalloc): New prototype. Omit needless casts.
7977 * alloc.c (xzalloc): New function. Omit needless casts.

8032 Problem reported by Troels Nielsen in
8033 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
8035 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8037 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
8038 This should be fixed in a better way; see Eli Zaretskii in
8039 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
8040 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
8042 * fileio.c (time_error_value): Rename from special_mtime.
8043 The old name's problems were noted by Eli Zaretskii in
8044 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
8046 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
8047 This variable's comment says Emacs needs at least one GDB-visible
8048 symbol of type enum pvec_type, to work around GDB problems.
8049 The symbol's value doesn't matter.
8051 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
8052 that causes compilation to fail on pre-C99 compilers.
8054 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
8056 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
8057 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
8059 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
8061 * buffer.c (init_buffer_once): Fix initialization of
8062 headers for buffer_defaults and buffer_local_symbols.
8063 Reported by Juanma Barranquero <lekktu@gmail.com>.
8065 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
8067 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
8068 * lisp.h (enum pvec_type): Use fewer bits.
8069 (PSEUDOVECTOR_SIZE_BITS): New constant.
8070 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
8071 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
8072 change in pvec_type.
8073 (PSEUDOVECTOR_TYPEP): New macro.
8074 (TYPED_PSEUDOVECTORP): Use it.
8075 * fns.c (internal_equal): Adapt code to extract pvectype.
8076 * emacs.c (gdb_pvec_type): Update type.
8077 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
8078 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
8079 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
8080 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
8081 (sweep_vectors): Use it. Use local var `total_bytes' instead of
8082 abusing vector->header.next.nbytes.
8083 (live_vector_p): Use PVEC_TYPE.
8084 (mark_object): Adapt code to extract pvectype. Use switch.
8086 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8088 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
8089 Tighten new eassert a bit.
8091 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
8093 Fix compilation with --enable-gcc-warnings and -O1
8095 * doprnt.c (doprnt): Change type of tem to int, initialize
8096 to avoid compiler warning. Add eassert.
8097 * search.c (simple_search): Initialize match_byte to avoid
8098 compiler warning. Add eassert.
8100 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8102 Avoid weird behavior with large horizontal scrolls.
8103 Without this change, for example, large hscroll values would
8104 mess up Emacs's display on Fedora 15 x86, presumably due to
8105 overflows in int calculations in the display code.
8106 Also, if buffers had long lines, Emacs would freeze.
8107 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
8108 (set_window_hscroll): New function, containing the old guts of
8109 Fset_window_hscroll. Return the clipped value.
8110 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
8111 This avoids the need to check against PTRDIFF_MAX.
8113 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
8115 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
8117 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
8119 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8121 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
8122 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
8123 since GCC 4.4.6 issues a bogus warning for them.
8125 Fix bugs in file timestamp newness comparisons.
8126 * fileio.c (Ffile_newer_than_file_p):
8127 * lread.c (Fload): Use full timestamp resolution of files,
8128 not just the 1-second resolution, so that files that are only
8129 slightly newer still count as newer.
8130 * fileio.c (Ffile_newer_than_file_p): Don't assume file
8131 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
8133 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
8135 * fileio.c: Improve handling of file time marker. (Bug#11852)
8136 (special_mtime): New function.
8137 (Finsert_file_contents, Fverify_visited_file_modtime):
8138 Use it to set special mtime values consistently.
8140 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
8142 * fileio.c (Finsert_file_contents): Properly handle st_mtime
8143 marker for non-existing file. (Bug#11852)
8145 2012-07-03 Glenn Morris <rgm@gnu.org>
8147 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
8148 and did not make it into globals.h).
8150 2012-07-03 Tom Tromey <tromey@redhat.com>
8152 * window.c (Fset_window_margins, Fset_window_fringes)
8153 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.

8196 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
8197 values which aren't power of 2.
8198 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
8199 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
8202 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
8204 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
8206 * alloc.c (mark_object): Revert part of last patch to use `switch'.
8208 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8210 * alloc.c (allocate_vector_block): Remove redundant
8211 calls to mallopt if DOUG_LEA_MALLOC is defined.
8212 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
8213 avoid calls to mallopt if zero_vector is returned.
8215 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8217 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
8218 is enabled, avoid dereferencing NULL current_sblock if
8221 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8223 Cleanup basic buffer management.
8224 * buffer.h (struct buffer): Change layout to use generic vector
8225 marking code. Fix some comments. Change type of 'clip_changed'
8226 to bitfield. Remove unused #ifndef old.
8227 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
8228 (GET_OVERLAYS_AT): Fix indentation.
8229 (for_each_per_buffer_object_at): New macro.
8230 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
8231 (Fbuffer_local_variables): Use it.
8232 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
8233 * alloc.c (allocate_buffer): Adjust to match new layout of
8234 struct buffer. Fix comment.
8235 (mark_overlay): New function.
8236 (mark_buffer): Use it. Use mark_vectorlike to mark normal
8237 Lisp area of struct buffer.
8238 (mark_object): Use it. Adjust marking of misc objects
8239 and related comments.
8241 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
8243 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
8244 wrapper that is not needed because the wrapped code is a no-op (zero
8245 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
8246 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
8248 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
8250 * alloc.c (mark_buffer): Simplify. Remove prototype.
8251 (mark_object): Add comment. Reorganize marking of vector-like
8252 objects. Use CHECK_LIVE for all vector-like objects except buffers
8253 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
8254 Avoid redundant calls to mark_vectorlike for bool vectors.
8256 2012-06-30 Glenn Morris <rgm@gnu.org>
8258 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
8260 * epaths.in (PATH_SITELOADSEARCH): New.
8261 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
8262 This is rather than relying on --enable-locallisppath elements
8263 having "site-lisp" in their names. (Bug#10208#25, 11658)
8265 2012-06-30 Eli Zaretskii <eliz@gnu.org>
8267 * w32proc.c (sys_select): Accept and ignore one more argument.
8269 * w32.c (emacs_gnutls_pull): Call select with one more argument.
8271 * sysselect.h [DOS_NT]: Don't include sys/select.h.
8272 (pselect) [!MS_DOS]: Redirect to sys_select.
8274 * sysdep.c: Don't include dos.h and dosfns.h.
8276 * process.c (sys_select):
8277 * msdos.c (sys_select): Accept one more argument and ignore it.
8279 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
8280 adapt data types and code to that.
8283 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
8284 which clashes with the gnulib function of the same name.
8286 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
8288 * font.c (font_style_to_value, font_style_symbolic)
8289 (font_prop_validate_style): Add type checks for values in
8292 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
8294 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
8297 2012-06-29 Eli Zaretskii <eliz@gnu.org>
8299 * xdisp.c (try_window_id): Undo last change.
8301 * w32.c (getwd): Adjust commentary about startup_dir.
8302 (init_environment): Always call sys_access, even in non-MSVC
8303 builds. Don't chdir to the directory of the Emacs executable.
8304 This undoes code from 1997 which was justified by the need to
8305 "avoid conflicts when removing and renaming directories". But its
8306 downside was that every relative file name was being interpreted
8307 relative to the directory of the Emacs executable, which can never
8308 be TRT. In particular, it broke sys_access when called with
8309 relative file names.
8310 (sys_access): Map GetLastError to errno.
8312 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8314 * window.h (struct window): Change type of 'fringes_outside_margins'

8318 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
8321 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>

8324 Add QUIT to make the loop interruptible.
8326 2012-06-29 Glenn Morris <rgm@gnu.org>
8328 * charset.c (init_charset): Make lack of etc/charsets fatal.
8330 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8332 * editfns.c (region_limit): Fix type mismatch.
8334 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8336 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
8337 undefined. Convert from xassert to eassert.
8338 * nsmenu.m: Convert from xassert to eassert.
8339 * nsterm.m: Likewise.
8341 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
8343 * editfns.c (region_limit): Clip to narrowing (bug#11770).
8345 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
8347 Avoid integer overflow on scroll-left and scroll-right.
8348 * window.c (HSCROLL_MAX): New macro.
8349 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
8350 overflow when requested scroll falls outside ptrdiff_t range.
8352 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
8354 * window.h (struct window): Change type of 'hscroll',
8355 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
8356 'last_modified' and 'last_overlay_modified' to EMACS_INT.
8357 Adjust users accordingly.
8358 * xdisp.c (try_cursor_movement): Replace type check with eassert.
8359 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
8360 from EMACS_INT to ptrdiff_t.
8361 (make_window): Omit redundant initialization.
8363 2012-06-28 Juanma Barranquero <lekktu@gmail.com>

8367 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
8369 * window.h (struct window): Change type of 'use_time' and

8432 avoid GCC warning about unused macro.

8436 * alloc.c (allocate_string): Omit intervals initialization.
8437 * alloc.c (make_uninit_multibyte_string): Initialize intervals
8438 as in make_pure_string and make_pure_c_string.
8440 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
8442 * alloc.c (allocate_string): Fix last change.
8444 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>

8494 * alloc.c: Remove build_string.
8495 * lisp.h: Define build_string as static inline. This provides
8496 a better opportunity to optimize away calls to strlen when the
8497 function is called with compile-time constant argument.
8498 * image.c (imagemagick_error): Convert to build_string.
8499 * w32proc.c (sys_spawnve): Likewise.
8500 * xterm.c (x_term_init): Likewise.
8502 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
8504 Use sprintf return value instead of invoking strlen on result.
8505 In the old days this wasn't portable, since some sprintf
8506 implementations returned char *. But they died out years ago and
8507 Emacs already assumes sprintf returns int.
8508 Similarly for float_to_string.
8509 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
8510 * ccl.c (ccl_driver):
8511 * character.c (string_escape_byte8):

8514 * print.c (print_object):
8515 * xdisp.c (message_dolog):
8516 * xfns.c (syms_of_xfns):
8517 Use sprintf or float_to_string result to avoid need to call strlen.
8518 * data.c (Fnumber_to_string):
8519 Use make_unibyte_string, since the string must be ASCII.
8520 * lisp.h, print.c (float_to_string): Now returns int length.
8521 * term.c (produce_glyphless_glyph):
8522 Use sprintf result rather than recomputing it.
8524 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
8525 * Makefile.in (ALL_CFLAGS):
8526 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

8557 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

8562 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
8563 instead of truncating it to 63 (admittedly a generous limit).
8565 * process.c: Fix spelling and caps in comments.
8567 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
8569 * emacs.c (setpgrp): Remove definition, unused.

8615 * sound.c (sound_warning, parse_sound):
8616 Remove unnecessary forward decls.

8691 Don't assume EMACS_TIME and struct timeval are the same type.
8693 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
8695 Support higher-resolution time stamps (Bug#9000).
8696 The time stamps are only nanosecond-resolution at the C level,
8697 since that's the best that any real-world system supports now.
8698 But they are picosecond-resolution at the Lisp level, as that's
8699 easy, and leaves room for future OS improvements.
8701 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
8704 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
8705 Don't get current time unless it's needed.
8707 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
8708 now provides it if it's absent.
8709 (start_atimer): Port to higher-res time stamps.
8710 Check for time stamp overflow. Don't get current time more
8711 often than is needed.
8713 * buffer.h (struct buffer): Buffer modtime now has high resolution.
8714 Include systime.h, not time.h.
8715 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
8717 * dired.c: Include stat-time.h.
8718 (Ffile-attributes): File times now have higher resolution.

8721 (struct image): Timestamp now has higher resolution.
8723 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
8724 has at least microseconds now. All uses removed.
8725 (update_frame, update_single_window, update_window, update_frame_1)
8726 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
8727 (duration_to_sec_usec): Remove; no longer needed.
8729 * editfns.c (time_overflow): Now extern.

8735 (decode_time_components, lisp_seconds_argument): New functions.
8736 (make_time): Now static.
8737 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
8738 Report an error if the time is invalid, rather than having the caller
8741 * fileio.c: Include <stat-time.h>
8742 (Fcopy_file): Copy higher-resolution time stamps.
8743 Prefer to set the time stamp via a file descriptor if that works.

8745 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
8746 (Fvisited_file_modtime, Fset_visited_file_modtime):
8747 Support higher-resolution time stamps.
8749 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
8751 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
8753 * image.c (prepare_image_for_display, clear_image_cache)
8754 (lookup_image): Port to higer-resolution time stamps.
8756 * keyboard.c (start_polling, bind_polling_period):
8757 Check for time stamp overflow.
8758 (read_char, kbd_buffer_get_event, timer_start_idle)
8759 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
8760 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
8761 Port to higher-resolution time stamps. Do not assume time_t is signed.
8762 (decode_timer): New function. Timers are now vectors of length 9,
8763 not 8, to accommodate the picosecond component.
8764 (timer_check_2): Use it.
8766 * nsterm.m (select_timeout, timeval_subtract): Remove.
8767 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
8768 as they're a bit more accurate and handle overflow better.
8769 (ns_select): Change prototype to be compatible with pselect.
8770 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
8771 * nsterm.h (ns_select): Adjust prototype.
8773 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
8774 us-resolution time stamps.
8775 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
8777 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
8779 * lisp.h (time_overflow): New decl.
8780 (wait_reading_process_output): First arg is now intmax_t, not int,
8781 to accommodate larger waits.
8783 * process.h (struct Lisp_Process.read_output_delay):
8784 Now counts nanoseconds, not microseconds.
8785 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
8787 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
8788 (wait_reading_process_output):
8789 Port to ns-resolution time stamps.
8790 (Faccept_process_output, wait_reading_process_output):
8791 Check for time stamp overflow. Do not assume time_t is signed.
8792 (select_wrapper): Remove; we now use pselect.
8793 (Fprocess_attributes): Now generates ns-resolution time stamps.
8795 * sysdep.c: Include utimens.h. Don't include utime.h
8796 or worry about struct utimbuf; gnulib does that for us now.
8797 (gettimeofday): Remove; gnulib provides a substitute.
8798 (make_timeval): New function.
8799 (set_file_times): Now sets ns-resolution time stamps.
8800 New arg FD; all uses changed.
8801 (time_from_jiffies, ltime_from_jiffies, get_up_time)
8802 (system_process_attributes):
8803 Now returns ns-resolution time stamp. All uses changed.
8804 Check for time stamp overflow.
8806 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
8807 provides a substitute now.
8809 * systime.h: Include timespec.h rather than sys/time.h and time.h,
8810 since it guarantees struct timespec.
8811 (EMACS_TIME): Now struct timespec, so that we can support
8812 ns-resolution time stamps.
8813 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
8814 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
8815 (EMACS_USECS): Remove.
8816 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
8817 so multiply the arg by 1000 before storing it.
8818 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
8820 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
8821 Port to ns-resolution time stamps.
8822 (EMACS_TIME_NEG_P): Remove; replaced by....
8823 (EMACS_TIME_SIGN): New macro.
8824 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
8825 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
8826 (set_file_times, make_time, lisp_time_argument): Adjust signature.
8827 (make_timeval, make_lisp_time, decode_time_components): New decls.
8828 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
8829 that it mishandled time_t overflow. You can't compare by subtracting!
8830 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
8831 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
8833 * term.c: Include <sys/time.h>.
8834 (timeval_to_Time): New function, for proper overflow wraparound.

8839 (Fprimitive_undo): Use them when restoring time stamps.
8841 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
8842 (w32_get_internal_run_time):
8843 Port to higher-resolution Emacs time stamps.
8844 (ltime): Now accepts single 64-bit integer, as that's more convenient
8847 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
8849 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
8850 for compatibility with pselect. Support ns-resolution time stamps.
8852 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
8854 * xselect.c (wait_for_property_change, x_get_foreign_selection):
8855 Check for time stamp overflow, and support ns-resolution time stamps.
8857 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
8858 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
8859 (timeval_subtract): Remove; no longer needed.
8860 (XTflash, XTring_bell, x_wait_for_event):
8861 Port to ns-resolution time stamps. Don't assume time_t is signed.
8863 2012-06-22 Chong Yidong <cyd@gnu.org>

8867 2012-06-22 Eli Zaretskii <eliz@gnu.org>
8869 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
8870 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
8871 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
8872 staticidx goes up to 1597 out of 1600 = 0x640.)
8874 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
8876 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
8877 Otherwise, the umask might be mistakenly 0 while handling input signals.

8898 (unwind_format_mode_line): Restore them.
8899 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
8901 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
8902 since tty frames can be explicitly named.
8903 (prepare_menu_bars): Likewise.
8905 * term.c (Ftty_top_frame): New function.
8907 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

8910 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
8911 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
8912 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
8913 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
8914 (METER_1, METER_2): Simplify.

8922 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
8923 gets killed during executing of this function (Bug#11665).
8924 Try to always return Qt when the buffer has been actually killed.
8925 (Vkill_buffer_query_functions): In doc-string say that functions
8926 run by this hook should not change the current buffer.
8928 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
8930 Fix recently-introduced process.c problems found by static checking.

8948 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
8950 * lisp.h (eassert): Assume C89 or later.
8951 This removes the need for CHECK.
8952 (CHECK): Remove. Its comments about always evaluating its
8953 argument were confusing, as 'eassert' typically does not evaluate
8956 * coding.c (produce_chars): Use ptrdiff_t, not int.
8958 * xterm.c (x_draw_underwave): Check for integer overflow.
8959 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

9053 If all the glyphs of the glyph row came from strings, and we have no
9054 cursor positioning clues, put the cursor on the first glyph of the

9087 Simplify now that USE_LSB_TAG is always defined.
9088 (TYPEMASK, XINT) [USE_LSB_TAG]: Remove unnecessary cast.
9089 (make_number) [!USE_LSB_TAG]: Use INTMASK; that's simpler.

9111 * frame.c (delete_frame): Remove outdated comment.
9112 * w32fns.c (Fw32_register_hot_key): Use XLI instead of checking
9113 USE_LISP_UNION_TYPE.

9132 USE_LISP_UNION_TYPE + USE_LSB_TAG cleanup (Bug#11604)
9133 * alloc.c (make_number) [!defined make_number]:

9137 * data.c (Fmake_variable_buffer_local, Fmake_local_variable):
9138 * ftfont.c (ftfont_driver): Use LISP_INITIALLY_ZERO.
9139 * lisp.h (USE_LSB_TAG): Allow the builder to compile with

9141 USE_LSB_TAG now is always defined to be either 0 or 1.
9143 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
9144 code works fine either way, and efficiency is not a concern here,
9145 as the union type is for debugging, not for production.
9146 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
9147 Use an inline function on all platforms when using the union type,
9148 since this is simpler and 'static inline' can be used portably
9150 (LISP_INITIALLY_ZERO): New macro.
9151 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
9152 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.

9179 * s/gnu-kfreebsd.h, s/gnu-linux.h, s/gnu.h, s/hpux10-20.h:
9180 * s/irix6-5.h, s/ms-w32.h, s/msdos.h, s/template.h:
9181 * s/usg5-4-common.h: Move SYSTEM_TYPE to configure.

9221 dbus_type_is_basic if available.
9222 (xd_extract_signed, xd_extract_unsigned): Rename from
9223 extract_signed and extract_unsigned, respectively. Adapt callers.
9225 2012-06-09 Chong Yidong <cyd@gnu.org>

9234 * xdisp.c (vmessage): Treat frame message as multibyte.
9235 Without this change, (let ((§ 1)) (make-variable-buffer-local '§))
9236 would generate the diagnostic "Making \302\247 buffer-local while
9239 2012-06-08 Eli Zaretskii <eliz@gnu.org>
9241 * dispnew.c (showing_window_margins_p): Undo last change, which

9255 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
9257 2012-06-08 Eli Zaretskii <eliz@gnu.org>
9259 * alloc.c (allocate_vectorlike): Fix last change.
9261 2012-06-08 Dmitry Antipov <dmantipov@yandex.ru>
9263 Block-based vector allocation of small vectors.
9264 * lisp.h (struct vectorlike_header): New field `nbytes',
9265 adjust comment accordingly.

9290 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
9292 * doprnt.c (doprnt): Truncate multibyte char correctly.
9293 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
9294 would mishandle a string argument "Xc" if X was a multibyte
9295 character of length 2: it would truncate after X's first byte
9296 rather than including all of X.
9298 2012-06-06 Chong Yidong <cyd@gnu.org>
9300 * buffer.c (word_wrap): Doc fix.

9349 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
9350 Convert pctcpu and pctmem to Lisp float properly.
9351 Let the compiler fold better, as 100.0/0x8000 is exact.
9353 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
9355 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
9358 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
9360 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
9362 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
9364 For a 'struct window', replace some Lisp_Object fields to
9365 bitfields where appropriate, remove unused fields.
9366 * window.h (struct window): Remove unused 'last_mark_x' and
9367 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
9368 change its type from Lisp_Object to bitfield.
9369 Change type of 'force_start', 'optional_new_start',
9370 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
9371 fields from Lisp_Object to bitfield. Adjust users accordingly.
9373 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
9375 Pacify gcc -Wdouble-precision when using Xaw.
9376 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
9377 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
9378 Use 'float' consistently, rather than 'float' in most places
9379 and 'double' in a couple of places.
9381 2012-05-31 Eli Zaretskii <eliz@gnu.org>
9383 * xdisp.c (handle_stop): Detect whether we have overlay strings
9384 loaded by testing it->current.overlay_string_index to be
9385 non-negative, instead of checking whether n_overlay_strings is
9386 positive. (Bug#11587)
9388 2012-05-31 Chong Yidong <cyd@gnu.org>
9390 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
9392 * doc.c (Fsubstitute_command_keys): Doc fix.
9394 2012-05-31 Eli Zaretskii <eliz@gnu.org>
9396 * search.c (search_buffer): Remove calls to
9397 r_alloc_inhibit_buffer_relocation, as it is now called by
9398 maybe_unify_char, which was the cause of relocation of buffer text
9401 2012-05-31 Eli Zaretskii <eliz@gnu.org>
9403 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
9404 for the duration of call to load_charset, to avoid problems with
9405 callers of maybe_unify_char that access buffer text through C
9408 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
9409 decrement the inhibition flag, instead of just setting or
9412 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
9414 Remove obsolete '#define static' cruft.
9415 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
9416 This #undef was "temporary" in 2000; it is no longer needed
9417 now that '#define static' has gone away.
9418 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
9419 (gray_bitmap_bits): Remove; no longer needed.
9420 All uses replaced with definiens.
9421 * xterm.c: Include "bitmaps/gray.xbm".
9423 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
9425 Clean up __executable_start, monstartup when --enable-profiling.
9426 The following changes affect the code only when profiling.
9427 * dispnew.c (__executable_start): Rename from safe_bcopy.
9428 Define only on platforms that need it.
9429 * emacs.c: Include <sys/gmon.h> when profiling.
9430 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
9431 (__executable_start): Remove decl, since lisp.h does it now.
9432 (safe_bcopy): Remove decl; no longer has that name.
9433 (main): Coalesce #if into single bit of code, for simplicity.
9434 Cast pointers to uintptr_t, since standard libraries want integers

9463 Do not create empty overlays with the evaporate property (Bug#9642).
9464 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
9465 Bug#9642, but explicitly check that the buffer the overlay would
9466 be moved to is live and rearrange lines to make sure that errors
9467 will not put the overlay in an inconsistent state.
9468 (Fdelete_overlay): Cosmetics.
9470 2012-05-28 Eli Zaretskii <eliz@gnu.org>
9472 * w32term.c (my_bring_window_to_top): New function.
9473 (x_raise_frame): Use handle returned by DeferWindowPos, which

9484 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
9486 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
9487 This avoids undefined behavior that might cause the eassert
9488 to not catch an out-of-range value.
9490 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
9492 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

9502 when referring to sectname field in printf format.
9504 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
9506 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
9507 Only r_alloc_inhibit_buffer_relocation needed to be added;
9508 the others were already declared.
9510 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
9511 before checking whether it's out of range. Put the check inside
9513 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
9515 2012-05-27 Ken Brown <kbrown@cornell.edu>
9517 * callproc.c (Fcall_process): Restore a line that was accidentally
9518 commented out in the 2011-02-13 change (bug#11547).

9522 * lisp.h [REL_ALLOC]: Add prototypes for external functions
9523 defined on ralloc.c.
9525 * buffer.c [REL_ALLOC]: Remove prototypes of
9526 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
9527 they are now on lisp.h.
9529 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
9531 * search.c (search_buffer): Use it to inhibit relocation of buffer
9532 text while re_search_2 is doing its job, because re_search_2 is
9533 passed C pointers to buffer text. (Bug#11519)
9535 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
9538 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
9539 state after an additional call to move_it_in_display_line_to, keep
9540 the values of it->max_ascent and it->max_descent found for the
9542 (pos_visible_p): Revert the comparison against bottom_y to what it
9543 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
9546 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
9548 Fix coding-related core dumps with gcc -ftrapv.
9549 The code was computing A - B, where A and B are pointers, and B is
9550 random garbage. This can lead to core dumps on platforms that
9551 have special pointer registers, and it also leads to core dumps on
9552 x86-64 when compiled with gcc -ftrapv. The fix is to compute
9553 A - B only when B is initialized properly.
9554 * coding.c (coding_set_source, coding_set_destination): Return void.
9555 (coding_change_source, coding_change_destinations): New functions,
9556 with the old behaviors of coding_set_source and coding_set_destination.
9557 All callers that need an offset changed to use these new functions.

9577 gen_help_event to produce help-echo message in the echo area.
9578 Call clear_mouse_face if mouse_face_hidden is set in the mouse
9581 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>

9584 with GCC 4.7.0 on x86-64.
9586 2012-05-26 Eli Zaretskii <eliz@gnu.org>
9588 * bidi.c (bidi_mirror_char): Revert last change: an int is
9589 definitely wide enough here.
9591 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
9593 Fix integer width and related bugs (Bug#9874).

9604 (allocate_pseudovector):
9605 Use int, not EMACS_INT, where int is wide enough.
9606 (inhibit_garbage_collection, Fgarbage_collect):

9625 (Foverlay_recenter, last_overlay_modification_hooks_used)
9626 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
9627 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9628 (validate_region): Omit unnecessary test for b <= e,
9629 since that's guaranteed by the previous test.
9630 (adjust_overlays_for_delete): Avoid pos + length overflow.
9631 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
9632 (report_overlay_modification):
9633 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9634 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):

9643 not int, to avoid needless 32-bit limit on 64-bit hosts.
9644 (exec_byte_code): Use tighter memory-full test, one that checks
9645 for alloca overflow. Don't compute the address of the object just
9646 before an array, as that's not portable. Use EMACS_INT, not
9647 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
9648 * callint.c (Fcall_interactively):
9649 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

9661 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9662 (casify_object): Avoid integer overflow when overallocating buffer.
9663 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
9664 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
9665 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
9666 * category.h (CATEGORYP): Don't assume arg is nonnegative.
9667 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
9668 integers are now checked earlier. All uses replaced with XINT.
9670 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9671 For CCL_MapSingle, check that content and value are in int range.
9672 (ccl_driver, Fregister_code_conversion_map):
9673 Check that Vcode_version_map_vector is a vector.
9674 (resolve_symbol_ccl_program): Check that vector header is in range.
9675 Always copy the vector, so that we can check its contents reliably
9676 now rather than having to recheck each instruction as it's being
9677 executed. Check that vector words fit in 'int'.
9678 (ccl_get_compiled_code, Fregister_ccl_program)
9679 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
9680 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
9681 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
9682 contents are in range.
9683 (Fccl_execute_on_string): Check that status is in range.
9684 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
9685 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
9686 Accept and return EMACS_INT, not int, because callers can pass values

9692 (string_escape_byte8, Fget_byte):
9693 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9694 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
9695 avoid mishandling large integers.
9696 * character.h: Adjust decls to match defn changes elsewhere.

9705 (Fdefine_charset_internal): Check ranges here, more carefully.
9706 Don't rely on undefined behavior with signed left shift overflow.
9707 Don't assume unsigned int fits into fixnum, or that fixnum fits
9708 into unsigned int. Don't require max_code to be a valid fixnum;
9709 that's not true for gb10830 4-byte on a 32-bit host. Allow
9710 invalid_code to be a cons, for the same reason. Require code_offset
9711 to be a character. Avoid int overflow if max_char is close
9713 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
9714 this is intended anyway and avoids some undefined behavior.
9715 (load_charset_map): Pass unsigned, not int, as 2nd arg of
9716 INDEX_TO_CODE_POINT, as that's what it expects.
9717 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
9718 * charset.h (DECODE_CHAR): Return int, not unsigned;
9719 this is what was intended anyway, and it avoids undefined behavior.
9720 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
9721 integer-overflow issues.
9722 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
9723 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
9724 where the argument is EMACS_INT, and this behavior is not intended.
9725 * chartab.c (Fmake_char_table, Fset_char_table_range)
9726 (uniprop_get_decoder, uniprop_get_encoder):
9727 Don't assume fixnum fits in int.
9728 * cmds.c (move_point): New function, that does the gist of
9729 Fforward_char and Fbackward_char, but does so while checking
9730 for integer overflow more accurately.
9731 (Fforward_char, Fbackward_char): Use it.
9732 (Fforward_line, Fend_of_line, internal_self_insert)
9733 (internal_self_insert):
9734 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9735 Fix a FIXME, by checking for integer overflow when calculating
9736 target_clm and actual_clm.

10381 * xterm.c (x_x_to_emacs_modifiers):
10382 Don't assume EMACS_INT overflows nicely into int.
10383 (x_emacs_to_x_modifiers): Use EMACS_INT, not int, because values
10384 may come from Lisp.

10397 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>

10401 (unreadpure): Remove function.
10402 (readevalloop): Don't call read_list with -1 flag.

10415 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
10417 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
10420 This directory predates autoconf and is no longer needed nowadays.

10425 * Makefile.in (M_FILE): Remove. All uses removed.
10426 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS):
10427 * lisp.h (USE_LSB_TAG):
10428 * mem-limits.h (EXCEEDS_LISP_PTR):
10429 Use VAL_MAX, not VALBITS, in #if.
10430 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
10431 (EMACS_UINT): Define unconditionally now.
10432 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
10433 (BITS_PER_EMACS_INT): New constants, replacing
10434 what used to be in config.h, but not useful in #if.
10435 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
10436 define them any more.
10437 (VAL_MAX): New macro.
10439 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
10440 BITS_PER_EMACS_INT, in #if.
10441 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
10442 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
10443 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:

10445 Move here from removed file m/intel386.h.
10446 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
10447 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
10449 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
10451 Assume C89 or later.
10452 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.

10476 * xfns.c (x_in_use): Remove `static' qualifier.
10477 * xterm.h (x_in_use): Declare.
10478 * xgselect.c: Include xterm.h.
10479 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
10480 and `display_arg' (bug#9754).
10482 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>

10503 (Fword_search_forward, Fword_search_backward_lax)
10504 (Fword_search_forward_lax): Move functions to isearch.el
10505 (bug#10145, bug#11381).
10507 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
10509 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
10511 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
10513 * lread.c (init_obarray): Declare Qt and Qnil as special.
10515 2012-05-14 Glenn Morris <rgm@gnu.org>
10517 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
10518 Put "libexec" before "bin", for the sake of init_callproc_1.
10520 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
10522 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
10524 * unexaix.c: Port to more-recent AIX compilers.
10525 (report_error, report_error_1, make_hdr, copy_sym)
10526 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
10527 Make arguments const char *, not char *, to avoid violations of C
10528 standard and to fix some AIX warnings reported by Gilles Pion.
10530 2012-05-14 Eli Zaretskii <eliz@gnu.org>
10532 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
10533 already have overlays loaded.
10534 (handle_single_display_spec): Before returning without displaying
10535 fringe bitmap, synchronize the bidi iterator with the main display
10536 iterator, by calling iterate_out_of_display_property.
10537 (iterate_out_of_display_property): Detect buffer iteration by
10538 testing that it->string is a Lisp string.
10539 (get_next_display_element): When the current object is exhausted,
10540 and there's something on it->stack, call set_iterator_to_next to
10541 proceed with what's on the stack, instead of returning zero.
10542 (set_iterator_to_next): If called at the end of a Lisp string,
10543 proceed to consider_string_end without incrementing string
10544 position. Don't increment display vector index past the end of
10545 the display vector. (Bug#11417)
10546 (pos_visible_p): Don't report a position visible when move_it_to
10547 stopped at the last line of window, which happens to be scanned
10548 backwards by the bidi iteration. (Bug#11464)
10550 2012-05-14 Eli Zaretskii <eliz@gnu.org>
10552 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
10553 and right-margin display specs even if the spec is invalid or we
10554 are on a TTY, and thus unable to display on the fringes.
10555 That's because the text with the property will not be displayed anyway,
10556 so we need to signal to the caller that this is a "replacing"
10557 display spec. This fixes display when the spec is invalid or we
10560 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
10562 * unexaix.c (make_hdr): Fix typo in prototype.
10563 This bug broke the build on AIX. Problem reported by Gilles Pion.
10565 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
10567 * keyboard.c (kbd_buffer_get_event): Read special events also in
10568 batch mode. (Bug#11415)
10570 2012-05-12 Glenn Morris <rgm@gnu.org>
10572 * ns.mk: Update for ns_appbindir no longer having trailing "/".
10574 2012-05-12 Eli Zaretskii <eliz@gnu.org>
10576 * lisp.mk (lisp): Add newcomment.elc.
10578 2012-05-12 Glenn Morris <rgm@gnu.org>
10580 * Makefile.in (MKDIR_P): New, set by configure.
10581 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
10583 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
10585 Remove unused function hourglass_started.
10586 * dispextern.h (hourglass_started):
10587 * w32fns.c (hourglass_started):
10588 * xdisp.c (hourglass_started): Remove.
10590 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
10592 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
10593 Update dependencies.
10595 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
10597 * xgselect.c (xg_select): Put maxfds+1 into a var.
10598 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
10600 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
10602 2012-05-10 Dave Abrahams <dave@boostpro.com>
10604 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
10605 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
10607 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
10609 * dbusbind.c (xd_registered_buses): New internal Lisp object.
10610 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
10611 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
10612 Initialize xd_registered_buses.
10614 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
10616 Untag more efficiently if USE_LSB_TAG.
10617 This is based on a proposal by YAMAMOTO Mitsuharu in
10618 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
10619 For an admittedly artificial (nth 8000 longlist) benchmark on
10620 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
10621 Emacs's overall text size by 1%.
10622 * lisp.h (XUNTAG): New macro.
10623 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
10624 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
10625 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
10626 * eval.c (Fautoload):
10627 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
10628 * frame.h (XFRAME): Use XUNTAG.
10630 Port recent dbusbind.c changes to 32-bit --with-wide-int.
10631 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
10632 Remove unportable assumptions about print widths of types like
10634 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
10635 intptr_t when converting between pointer and integer, to avoid GCC
10636 warnings about wrong width.
10638 2012-05-09 Eli Zaretskii <eliz@gnu.org>
10640 * w32proc.c (new_child): Force Windows to reserve only 64KB of
10641 stack for each reader_thread, instead of defaulting to 8MB
10642 determined by the linker. This avoids failures in creating
10643 subprocesses on Windows 7, see the discussion in this thread:

10648 Fix up display of the *Minibuf-0* buffer in the mini window.
10649 * keyboard.c (read_char): Don't clear the echo area if there's no
10651 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
10652 contents of *Minibuf-0*) if there's no message displayed in its stead.
10654 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
10656 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
10659 2012-05-06 Chong Yidong <cyd@gnu.org>
10661 * lisp.mk (lisp): Update.
10663 2012-05-05 Jim Meyering <meyering@redhat.com>
10665 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
10667 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
10669 * data.c (PUT_ERROR): New macro.
10670 (syms_of_data): Use it. Add new error type `user-error'.
10671 * undo.c (user_error): New function.
10672 (Fprimitive_undo): Use it.
10673 * print.c (print_error_message): Adjust print style for `user-error'.
10674 * keyboard.c (user_error): New function.
10675 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
10677 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
10679 Do not limit current-time-string to years 1000..9999.
10680 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
10681 (Fcurrent_time_string): Support any year that is supported by the
10682 underlying localtime representation. Don't use asctime, as it
10683 has undefined behavior for years outside the range -999..9999.
10685 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
10687 Fix race conditions involving setenv, gmtime, localtime, asctime.
10688 Without this fix, interrupts could mess up code that uses these
10689 nonreentrant functions, since setting TZ invalidates existing
10690 tm_zone or tzname values, and since most of these functions return
10691 pointers to static storage.
10692 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
10693 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
10694 Grow the critical sections to include not just invoking
10695 localtime/gmtime, but also accessing these functions' results
10696 including their tm_zone values if any, and any related TZ setting.
10697 (format_time_string): Last arg is now struct tm *, not struct tm **,
10698 so that the struct tm is saved in the critical section.
10699 All callers changed. Simplify allocation of initial buffer, partly
10700 motivated by the fact that memory allocation needs to be outside
10701 the critical section.
10703 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
10705 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
10706 with RESET_INTERVAL.
10708 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
10709 Remove duplicated buffer name initialization.
10711 2012-05-02 Jim Meyering <jim@meyering.net>
10713 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
10715 * xfns.c (x_window): Use xstrdup (Bug#11375).
10717 2012-05-02 Eli Zaretskii <eliz@gnu.org>
10719 * xdisp.c (pos_visible_p): If already at a newline from the
10720 display string before the 'while' loop, don't walk back the glyphs
10721 from it3.glyph_row. Solves assertion violation when the display
10722 string begins with a newline (egg.el). (Bug#11367)
10724 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
10726 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
10729 2012-05-01 Glenn Morris <rgm@gnu.org>
10731 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
10732 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
10733 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
10734 All were removed before 23.1.
10736 * dispnew.c: Remove HAVE_LIBNCURSES test;
10737 it is always true on relevant platforms.
10739 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
10740 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
10742 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
10744 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
10746 * .gdbinit (xpr): Remove checks for no longer existing misc types.
10747 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
10750 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
10752 Do not avoid creating empty evaporating overlays (Bug#9642).
10753 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
10754 That is, do not delete an evaporating overlay if it becomes
10755 empty after its bounds are adjusted to fit within its buffer.
10756 This fix caused other problems, and I'm reverting it until we get
10757 to the bottom of them.
10759 2012-04-27 Chong Yidong <cyd@gnu.org>
10761 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
10763 2012-04-27 Eli Zaretskii <eliz@gnu.org>
10765 * xdisp.c (pos_visible_p): If the window start position is beyond
10766 ZV, start the display from buffer beginning. Prevents assertion
10767 violation in init_iterator when the minibuffer window is scrolled
10768 via the scroll bar.
10770 * window.c (window_scroll_pixel_based): Likewise.
10772 2012-04-27 Chong Yidong <cyd@gnu.org>
10774 * keymap.c (where_is_internal): Doc fix (Bug#10872).
10776 2012-04-27 Glenn Morris <rgm@gnu.org>
10778 * fileio.c (Fcopy_file, Fset_file_selinux_context):
10779 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
10781 2012-04-27 Eli Zaretskii <eliz@gnu.org>
10783 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
10784 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
10786 2012-04-26 Eli Zaretskii <eliz@gnu.org>
10788 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
10789 display element, check also the underlying string or buffer
10790 character. (Bug#11341)
10792 * w32menu.c: Include w32heap.h.
10793 (add_menu_item): If the call to AppendMenuW (via
10794 unicode_append_menu) fails, disable Unicode menus only if we are
10795 running on Windows 9X/Me.
10797 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
10799 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
10800 (xgetint): Add missing shift for LSB tags.
10802 2012-04-24 Martin Rudalics <rudalics@gmx.at>
10804 * keyboard.c (read_char): Don't wipe echo area for select window
10805 events: These might get delayed via `mouse-autoselect-window'
10808 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
10810 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
10811 manipulation of :loaded-from data.
10813 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
10815 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
10816 now a cons (bug#11311).
10818 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
10820 Do not create empty overlays with the evaporate property (Bug#9642).
10821 * buffer.c (Fmove_overlay): Delete an evaporating overlay
10822 if it becomes empty after its bounds are adjusted to fit within
10823 its buffer. Without this fix, in a nonempty buffer (let ((o
10824 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
10825 yields an empty overlay that has the evaporate property, which is
10826 not supposed to happen.
10828 Fix minor GTK3 problems found by static checking.
10829 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)

10848 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
10849 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
10850 (__malloc_size_t, __malloc_ptrdiff_t):
10851 Remove. All uses removed, replaced by the definiens if needed,
10852 since we can assume C89 or better now.
10853 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.

10861 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
10862 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):

11032 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
11033 Remove one incorrect comment and fix another.

11037 * ralloc.c (ALIGNED, ROUND_TO_PAGE, HEAP_PTR_SIZE)
11038 (r_alloc_size_in_use, r_alloc_freeze, r_alloc_thaw): Remove; unused.
11039 (r_alloc_sbrk): Now static.
11041 Improve ralloc.c interface checking.
11042 See http://lists.gnu.org/archive/html/emacs-devel/2011-12/msg00720.html
11043 * buffer.c (ralloc_reset_variable, r_alloc, r_re_alloc)

11050 * alloc.c (which_symbols): Fix alignment issue / type clash.
11052 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
11054 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

11070 * s/netbsd.h, s/sol2-6.h:
11071 Remove definition of GC_MARK_STACK, since the default now works.
11072 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
11073 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
11074 no longer the default.
11075 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
11077 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
11079 * lread.c (lisp_file_lexically_bound_p):
11080 Fix hang at ";-*-\n" (bug#11238).
11082 2012-04-14 Eli Zaretskii <eliz@gnu.org>
11084 * xdisp.c (find_last_unchanged_at_beg_row): Don't consider a row
11085 "unchanged" if its end.pos is beyond ZV. (Bug#11199)
11087 2012-04-14 Jan Djärv <jan.h.d@swipnet.se>
11089 * nsterm.m (constrainFrameRect): Always constrain when there is only
11090 one screen (Bug#10962).
11092 2012-04-13 Ken Brown <kbrown@cornell.edu>
11094 * s/cygwin.h (PTY_OPEN): Don't try to close a bogus file descriptor.
11096 2012-04-13 Reuben Thomas <rrt@sc3d.org>
11098 * indent.c (Fmove_to_column): Change interactive spec (Bug#739).
11100 2012-04-11 Daniel Colascione <dancol@dancol.org>
11102 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
11103 against is gone. It's better to use vfork now so that when Cygwin
11104 gains a new, working vfork, we use it automatically (bug#10398).
11106 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
11108 * window.c (save_window_save): Obey window-point-insertion-type.

11121 (force_quit_count): New var.
11122 (handle_interrupt): Use it.
11124 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
11126 * w32.c (w32_delayed_load): Record the full path of the library
11127 being loaded (bug#10424).
11129 2012-04-09 Glenn Morris <rgm@gnu.org>
11131 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
11132 not just in the obarray, before snarfing them. (Bug#11036)
11134 * Makefile.in ($(leimdir)/leim-list.el):
11135 Pass EMACS rather than BUILT_EMACS.
11137 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
11139 * process.c (make_process):
11140 * process.h: Add integer `gnutls_handshakes_tried' member to
11143 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.
11144 Add convenience `GNUTLS_LOG2i' macro.
11146 * gnutls.c (gnutls_log_function2i): Convenience log function.
11147 (emacs_gnutls_read): Use new log functions,
11148 `gnutls_handshakes_tried' process member, and
11149 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
11150 attempts per process (connection).
11152 2012-04-09 Chong Yidong <cyd@gnu.org>
11154 * eval.c (Fuser_variable_p, user_variable_p_eh)
11155 (lisp_indirect_variable): Functions deleted.
11156 (Fdefvar): Caller changed.
11158 * callint.c (Finteractive, Fcall_interactively):
11159 * minibuf.c (Fread_variable): Callers changed.
11161 2012-04-09 Eli Zaretskii <eliz@gnu.org>
11163 * xdisp.c (set_cursor_from_row): If the display string appears in
11164 the buffer at position that is closer to point than the position
11165 after the display string, display the cursor on the first glyph of
11166 the display string. Fixes cursor display when a 'display' text
11167 property immediately follows invisible text. (Bug#11094)
11169 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
11171 composite.c: use 'double' consistently
11172 * composite.c (get_composition_id): Use 'double' consistently
11173 instead of converting 'float' to 'double' and vice versa; this is
11174 easier to understand and avoids a GCC warning.
11176 2012-04-09 Glenn Morris <rgm@gnu.org>
11178 * Makefile.in: Generate leim-list with bootstrap-emacs, in
11179 preparation for dumping it with emacs. (Bug#4789)
11180 (leimdir): New variable.
11181 ($(leimdir)/leim-list.el): New rule.
11182 (emacs$(EXEEXT)): Depend on leim-list.el.
11184 * buffer.c (Qucs_set_table_for_input): Remove. (Bug#9821)
11185 (Fget_buffer_create): Don't call Qucs_set_table_for_input.
11186 (init_buffer_once, syms_of_buffer): Remove Qucs_set_table_for_input.
11188 2012-04-08 Andreas Schwab <schwab@linux-m68k.org>
11190 * lisp.h (struct Lisp_Symbol): Add explicit padding to ensure
11193 2012-04-07 Juanma Barranquero <lekktu@gmail.com>
11195 * xml.c (init_libxml2_functions) [WINDOWSNT]:
11196 Remove unused local variable.
11198 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
11200 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
11201 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
11202 (mark_memory): Mark Lisp_Objects only if pointers might hide in
11203 objects, as mark_maybe_pointer will catch them otherwise.
11204 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
11205 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
11207 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
11209 Fix typo that broke non-Windows builds.
11210 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.
11212 2012-04-07 Eli Zaretskii <eliz@gnu.org>
11214 Support building on MS-Windows with libxml2.
11216 * makefile.w32-in (OBJ2): Add xml.$(O).
11217 (GLOBAL_SOURCES): Add xml.c.
11218 ($(BLD)/xml.$(O)): New dependency list.
11220 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
11221 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
11222 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
11223 [!WINDOWSNT]: New macros.
11224 (init_libxml2_functions, libxml2_loaded_p): New functions.
11225 (parse_region): Call fn_xmlCheckVersion instead of using the macro
11226 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
11227 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
11228 Calls xmlCleanupParser only if libxml2 was loaded (or statically
11230 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
11231 Call init_libxml2_functions before calling libxml2 functions.
11232 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
11234 * emacs.c: Don't include libxml/parser.h.
11235 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
11236 xmlCleanupParser directly.
11238 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
11240 2012-04-07 Eli Zaretskii <eliz@gnu.org>
11242 * indent.c (Fvertical_motion): If there is a display string at
11243 point, use it.vpos to compute how many lines to backtrack after
11244 move_it_to point. (Bug#11133)
11246 2012-04-06 Eli Zaretskii <eliz@gnu.org>
11248 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
11249 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
11250 about subtle differences between FETCH_CHAR* and STRING_CHAR*
11251 macros related to unification of CJK characters. For the details,
11252 see the discussion following the message here:
11253 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
11255 2012-04-04 Chong Yidong <cyd@gnu.org>
11257 * keyboard.c (Vdelayed_warnings_list): Doc fix.
11259 2012-04-01 Eli Zaretskii <eliz@gnu.org>
11261 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
11262 instead of alloca. (Bug#11138)
11264 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
11266 * w32menu.c (is_simple_dialog): Properly check lisp types.
11269 2012-03-31 Eli Zaretskii <eliz@gnu.org>
11271 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
11272 position we get to after a call to move_it_to fails the
11273 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
11274 only if we wind up in a string from display property. (Bug#11063)
11276 * window.c (Fdelete_other_windows_internal): Invalidate the row
11277 and column information about mouse highlight, so that redisplay
11278 restores it after reallocating the glyph matrices. (Bug#7464)
11280 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
11281 string comes from a `display' text property, use the buffer
11282 position of that property as if we actually saw that position in
11284 (move_it_by_lines): Remove the assertion that
11285 "it->current_x == 0 && it->hpos == 0" which can be legitimately
11286 violated when there's a before-string at the beginning of a line.
11289 2012-03-30 Eli Zaretskii <eliz@gnu.org>
11291 * xdisp.c (append_space_for_newline): If the default face was
11292 remapped, use the remapped face for the appended newline.
11293 (extend_face_to_end_of_line): Use the remapped default face for
11294 extending the face to the end of the line.
11295 (display_line): Call extend_face_to_end_of_line when the default
11296 face was remapped. (Bug#11068)
11298 2012-03-29 Eli Zaretskii <eliz@gnu.org>
11300 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
11302 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
11304 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
11306 2012-03-27 Glenn Morris <rgm@gnu.org>
11308 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
11311 2012-03-26 Kenichi Handa <handa@m17n.org>
11313 * dispextern.h (struct glyph): Fix previous change. Change the
11314 bit length of glyphless.ch to 25 (Bug#11082).
11316 2012-03-26 Chong Yidong <cyd@gnu.org>
11318 * keyboard.c (Vselection_inhibit_update_commands): New variable.
11319 (command_loop_1): Use it; inhibit selection update for
11320 handle-select-window too (Bug#8996).
11322 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
11324 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
11326 2012-03-25 Kenichi Handa <handa@m17n.org>
11328 * dispextern.h (struct glyph): Change the bit length of
11329 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
11331 2012-03-24 Eli Zaretskii <eliz@gnu.org>
11333 * s/ms-w32.h (tzname): Include time.h before redirecting to
11334 _tzname. Fixes the MSVC build. (Bug#9960)
11336 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
11338 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
11341 * xterm.c (XTread_socket): Only modify handling_signal if
11342 !SYNC_INPUT. (Bug#11080)
11344 2012-03-23 Eli Zaretskii <eliz@gnu.org>
11346 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
11347 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
11348 when fetching a multibyte character consumes more bytes than
11349 CHAR_BYTES returns, due to unification of CJK characters in
11350 string_char. (Bug#11073)
11352 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
11354 * process.c (wait_reading_process_output): Handle pty disconnect
11355 by refraining from sending oneself a SIGCHLD (bug#10933).
11357 2012-03-22 Chong Yidong <cyd@gnu.org>
11359 * dispextern.h (struct it): New member string_from_prefix_prop_p.
11361 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
11362 Mark string as coming from a prefix property.
11363 (handle_face_prop): Use default face for prefix strings (Bug#4281).
11364 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
11366 2012-03-21 Chong Yidong <cyd@gnu.org>
11368 * xfaces.c (Vface_remapping_alist): Doc fix.
11370 2012-03-20 Eli Zaretskii <eliz@gnu.org>
11372 * w32proc.c (Fw32_set_console_codepage)
11373 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
11376 2012-03-20 Chong Yidong <cyd@gnu.org>
11378 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
11379 to reflect default non-nil value of redisplay-dont-pause.
11381 2012-03-19 Kenichi Handa <handa@m17n.org>
11383 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
11384 it fit in a valid range (Bug#11003).
11386 2012-03-18 Eli Zaretskii <eliz@gnu.org>
11388 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
11389 that is not from display property, accept the row as a "cursor
11390 row" if one of the string's character has a non-nil `cursor'
11391 property. Fixes cursor positioning when there are newlines in
11392 overlay strings, e.g. in icomplete.el. (Bug#11035)
11394 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
11396 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
11398 2012-03-12 Chong Yidong <cyd@gnu.org>
11400 * eval.c (inhibit_lisp_code): Rename from
11401 inhibit_window_configuration_change_hook; move from window.c.
11403 * xfns.c (unwind_create_frame_1, Fx_create_frame):
11404 * window.c (run_window_configuration_change_hook)
11405 (syms_of_window): Callers changed.
11407 2012-03-11 Chong Yidong <cyd@gnu.org>
11409 * keymap.c (Fkey_description): Doc fix (Bug#9700).
11411 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
11413 2012-03-10 Chong Yidong <cyd@gnu.org>
11415 * frame.c (other_visible_frames): Don't assume the selected frame
11416 is visible (Bug#10955).
11418 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
11420 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
11422 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
11424 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
11425 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
11428 2012-03-03 Glenn Morris <rgm@gnu.org>
11430 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
11432 2012-03-02 Eli Zaretskii <eliz@gnu.org>
11434 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
11435 position past the first glyph_row that ends at ZV. (Bug#10902)
11436 (redisplay_window, next_element_from_string): Fix typos in
11438 (redisplay_window): Pass to move_it_vertically the margin in
11439 pixels, not in screen lines.
11441 2012-03-02 Glenn Morris <rgm@gnu.org>
11443 * buffer.c (buffer-list-update-hook): Doc fix.
11445 2012-02-29 Eli Zaretskii <eliz@gnu.org>
11447 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
11448 push_it before setting up the iterator for the first overlay
11449 string, even if we have an empty string loaded.
11450 (next_overlay_string): If there's an empty string on the iterator
11451 stack, pop the stack. (Bug#10903)
11453 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
11455 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
11456 Suggested by Stefan Monnier in
11457 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
11458 * alloc.c (widen_to_Lisp_Object): New static function.
11459 (mark_memory): Also mark Lisp_Objects by fetching pointer words
11460 and widening them to Lisp_Objects. This would work even if
11461 USE_LSB_TAG is defined and wide integers are used, which might
11462 happen in a future version of Emacs.
11464 2012-02-25 Chong Yidong <cyd@gnu.org>
11466 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
11469 * xselect.c (Fx_selection_exists_p): Doc fix.
11470 (x_clipboard_manager_save_all): Print an informative message
11471 before saving to clipboard manager.
11473 2012-02-24 Chong Yidong <cyd@gnu.org>
11475 * keyboard.c (process_special_events): Handle all X selection
11476 requests in kbd_buffer, not just the next one (Bug#8869).
11478 2012-02-23 Chong Yidong <cyd@gnu.org>
11480 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
11481 call when setting menu-bar-lines and tool-bar-lines parameters.
11482 (unwind_create_frame_1): New helper function.
11484 * window.c (inhibit_window_configuration_change_hook): New var.
11485 (run_window_configuration_change_hook): Obey it.
11486 (syms_of_window): Initialize it.
11488 2012-02-22 Chong Yidong <cyd@gnu.org>
11490 * xterm.c (x_draw_image_relief): Add missing type check for
11491 Vtool_bar_button_margin (Bug#10743).
11493 2012-02-21 Chong Yidong <cyd@gnu.org>
11495 * fileio.c (Vfile_name_handler_alist): Doc fix.
11497 * buffer.c (Fget_file_buffer): Protect against invalid file
11498 handler return value.
11500 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
11502 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
11503 when computing $valmask.
11505 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
11506 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
11507 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
11508 It's useless in that case, and it can cause problems on hosts
11509 that allocate halves of EMACS_INT values separately.
11510 Reported by Dan Horák. Diagnosed by Andreas Schwab in
11511 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
11512 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
11513 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
11514 it avoids undefined behavior on hosts where shifting right by more
11515 than the word width has undefined behavior.
11517 2012-02-19 Chong Yidong <cyd@gnu.org>
11519 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
11520 (Funhandled_file_name_directory, Ffile_name_as_directory)
11521 (Fdirectory_file_name, Fexpand_file_name)
11522 (Fsubstitute_in_file_name): Protect against invalid file handler
11523 return values (Bug#10845).
11525 2012-02-18 Eli Zaretskii <eliz@gnu.org>
11527 * .gdbinit (pitx): Fix incorrect references to fields of the
11530 2012-02-17 Chong Yidong <cyd@gnu.org>
11532 * syntax.c (Fscan_lists): Doc fix (Bug#10833).
11534 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>
11536 * image.c (MAX_IMAGE_SIZE): Increase from 6.0 to 10.0; see
11537 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
11539 2012-02-15 Chong Yidong <cyd@gnu.org>
11541 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
11542 marked as special. Also, starting docstrings with * is obsolete.
11544 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
11546 * gnutls.c (emacs_gnutls_write): Fix last change.

12132 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
12133 verifies glyph row's hash code--we have just reallocated the

12299 is set, removing the need for VIRT_ADDRESS_VARIES.
12300 (PURE_P): Use a more-efficient implementation that needs just one

12307 consistency with the new puresize.h.
12308 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
12309 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

12315 (erase_phys_cursor, update_window_cursor, show_mouse_face)
12316 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
12317 behave as if the cursor position were at the window margin.
12319 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
12320 and the cursor position is out of bounds, behave as if the cursor
12321 position were at the window margin. (Bug#10075)
12323 2011-11-18 Chong Yidong <cyd@gnu.org>
12325 * window.c (Fwindow_combination_limit): Make first argument

12346 * xdisp.c (row_hash): New function, body extracted from
12347 compute_line_metrics.
12348 (compute_line_metrics): Call row_hash, instead of computing the
12351 * dispnew.c (verify_row_hash): Call row_hash for computing the
12352 hash code of a row, instead of duplicating code from xdisp.c.
12354 * dispextern.h (row_hash): Add prototype.
12356 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
12358 * frame.c (delete_frame): Don't delete the terminal when the last

12412 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
12413 current_matrix and desired_matrix. (Bug#9990)
12414 (verify_row_hash) [XASSERTS]: New function.

12459 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
12461 Avoid some portability problems by eschewing 'extern inline' functions.
12462 The trivial performance wins aren't worth the portability hassles; see
12463 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
12465 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

12503 (Fset_window_new_total, Fset_window_new_normal)
12504 (Fwindow_resize_apply): Don't use term subwindow in doc-strings.
12505 (delete_all_subwindows): Rename to delete_all_child_windows.
12506 (Fdelete_other_windows_internal, Fset_window_configuration):
12507 Call delete_all_child_windows instead of delete_all_subwindows.
12508 * frame.c (delete_frame): Call delete_all_child_windows instead
12509 of delete_all_subwindows.
12511 2011-11-07 Paul Eggert <eggert@cs.ucla.edu>
12513 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
12514 This is also needed for porting to any host where GC_MARK_STACK is
12515 not GC_MAKE_GCPROS_NOOPS.
12516 (which_symbols): Use it.
12518 2011-11-07 Kenichi Handa <handa@m17n.org>
12520 * coding.c (coding_set_destination): Check coding->src_pos only
12521 when coding->src_object is a buffer (bug#9910).

12531 * xmenu.c (cleanup_widget_value_tree): New function.
12532 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
12533 calling free_menubar_widget_value_tree directly (Bug#9830).
12535 2011-11-06 Paul Eggert <eggert@cs.ucla.edu>
12537 Fix some portability problems with 'inline'.

12539 (window_box_width, window_box_left, window_box_left_offset)
12540 (window_box_right, window_box_right_offset): Declare extern.
12541 Otherwise, these inline functions do not conform to C99 and
12542 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
12543 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
12544 * intervals.c (adjust_intervals_for_insertion)
12545 (adjust_intervals_for_deletion): Now extern, because otherwise the
12546 extern inline functions 'offset_intervals' couldn't refer to it.
12547 (static_offset_intervals): Remove.
12548 (offset_intervals): Rewrite using the old contents of
12549 static_offset_intervals. The old version didn't conform to C99
12550 because an extern inline function contained a reference to an
12551 identifier with static linkage.
12553 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
12555 * keyboard.c (interrupt_signal): Don't call kill-emacs while in

12561 iterator's bidi_p flag if Vpurify_flag is non-nil. (Bug#9963)
12562 (Fcurrent_bidi_paragraph_direction): If Vpurify_flag is non-nil,
12563 return Qleft_to_right.

12572 (Fwindow_margins, Fwindow_fringes, Fwindow_scroll_bars)
12573 (Fwindow_vscroll): Doc fix.
12574 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
12575 argument, since it makes no sense to pass a live window and for
12576 consistency with window-child.

12604 (unwind_create_frame): New function (Bug#9943).
12605 (Fx_create_frame): Restructure code to be more similar to the one in
12606 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).
12607 Initialize image_cache_refcount if GLYPH_DEBUG (Bug#9943).
12608 Move terminal->reference_count++ just before making the frame official
12611 * nsterm.m (x_free_frame_resources): New function.
12612 (x_destroy_window): Move code to x_free_frame_resources.

12616 Move terminal->reference_count++ just before making the frame
12617 official. Move initialization of image_cache_refcount and
12618 dpyinfo_refcount before calling init_frame_faces (Bug#9943).

12657 * xdisp.c (note_mouse_highlight): If either of
12658 previous/next-single-property-change returns nil, treat that as
12659 the beginning or the end of the buffer. (Bug#9955)
12661 2011-11-04 Jan Djärv <jan.h.d@swipnet.se>
12663 * gtkutil.c (xg_make_tool_item): Add callbacks if one of wimage or

12686 (mouse_face_from_buffer_pos, note_mouse_highlight):
12687 Rename cover_string to disp_string.
12689 2011-11-01 Martin Rudalics <rudalics@gmx.at>

12692 Vtemp_buffer_show_specifiers.
12693 (Vtemp_buffer_show_specifiers): Remove unused variable.
12695 2011-10-30 Eli Zaretskii <eliz@gnu.org>
12697 * xdisp.c (try_cursor_movement): Make sure ROW isn't decremented
12698 past the beginning of the current glyph matrix.
12700 2011-10-30 Adam Sjøgren <asjo@koldfront.dk> (tiny change)
12702 * xterm.c: Include X11/Xproto.h if HAVE_GTK3.

12746 2011-10-29 Glenn Morris <rgm@gnu.org>
12748 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
12749 Not clear what it was for, and it causes various bugs. (Bug#9839)
12751 2011-10-28 Eli Zaretskii <eliz@gnu.org>
12753 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a

12755 condition to clear the mouse face.
12757 2011-10-28 Chong Yidong <cyd@gnu.org>

12773 2011-10-28 Eli Zaretskii <eliz@gnu.org>
12775 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
12776 <oslsachem@gmail.com> for helping to debug this.
12778 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)

12784 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
12786 (w32font_open_internal, compute_metrics):
12787 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
12788 instead of calling the "wide" APIs directly.
12790 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
12792 * w32.h (syms_of_w32font): Add prototype.
12794 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
12796 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
12797 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
12798 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
12799 (Fmove_to_window_line): Doc fix.
12801 2011-10-27 Chong Yidong <cyd@gnu.org>
12803 * process.c (make_process): Set gnutls_state to NULL.
12805 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
12806 non-NULL, regardless of GNUTLS_INITSTAGE.
12807 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal

12834 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
12836 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).

12855 (bidi_resolve_weak): Don't enter the expensive loop if the current
12856 position is before next_en_pos. Record the bidi type of the first
12857 non-ET, non-BN character we find, in addition to its position.
12858 (bidi_level_of_next_char): Invalidate next_en_type when
12859 next_en_pos is over-stepped.
12861 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
12863 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
12864 * editfns.c: Rewrite current-time-zone so that it invokes
12865 the equivalent of (format-time-string "%Z") to get the time zone name.
12866 This fixes a bug when the time zone name contains characters that
12867 need converting from the system time locale to Emacs internal format.
12868 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
12869 that patch fixed format-time-string to do the conversion, but
12870 I forgot to fix current-time-zone.
12871 (format_time_string): New function, containing most of
12872 what Fformat_time_string used to contain.
12873 (Fformat_time_string): Rewrite in terms of format_time_string.
12874 This doesn't change this function's behavior.
12875 (current-time-zone): Rewrite to use format_time_string.
12876 This fixes the bug reported by Michael Schierl in
12877 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
12878 Jason Rumney's 2007-06-07 change worked around this bug, but
12880 * systime.h (tzname, timezone): Remove no-longer-used declarations.
12882 2011-10-19 Eli Zaretskii <eliz@gnu.org>
12884 * xdisp.c (start_display): If the character at POS is displayed
12885 via a display vector, reset IT->current.dpvec_index to zero.
12886 (try_window_reusing_current_matrix): If a line ends in a display
12887 vector or the next line starts in a display vector, continue
12888 redrawing the window even though the character position of
12889 start_row was reached.
12892 2011-10-18 Chong Yidong <cyd@gnu.org>
12894 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
12895 with nobreak-char-display too.
12897 2011-10-18 Eli Zaretskii <eliz@gnu.org>
12899 Fix part 3 of bug#9771.
12900 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
12901 (bidi_resolve_neutral): Don't enter the expensive loop looking for
12902 non-neutral characters if the current character is a paragraph
12903 separator (a.k.a. Newline). This avoids running the same
12904 expensive loop twice, once when we consume the preceding newline
12905 and the other time when the line actually needs to be displayed.
12906 Avoid the loop when we see neutrals on the base embedding level
12907 following a character whose directionality is the same as the
12908 paragraph's. This avoids running the expensive loop when a line
12909 ends in a long sequence of neutrals, like control characters.
12910 Add assertion against STRONG_AL type. Slightly rearrange code
12911 that determines the type of a neutral given the first non-neutral
12913 (bidi_level_of_next_char): Set next_en_pos to zero when
12914 invalidating its info.
12916 2011-10-17 Eli Zaretskii <eliz@gnu.org>
12918 * xdisp.c (push_display_prop): Determine whether to record string
12919 or buffer position by IT->string, not by IT->method. Allow
12920 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
12921 (move_it_vertically_backward): Don't look for character position
12922 immediately after the newline when in a continuation line.
12925 2011-10-15 Martin Rudalics <rudalics@gmx.at>
12927 * window.c (coordinates_in_window): Rewrite and delabelize
12928 vertical border check. (Bug#5357) (Bug#9618)
12930 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
12932 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
12933 errors in XSetWindowBorder (bug#9310).
12935 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
12937 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
12938 avoid crash when xmalloc overrun checking is enabled.
12940 2011-10-13 Eli Zaretskii <eliz@gnu.org>
12942 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
12943 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
12944 cursor motion with <left> and <right> arrow keys.
12946 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
12947 some callers set that themselves.
12949 2011-10-12 Eli Zaretskii <eliz@gnu.org>
12951 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
12952 display string and the previous row comes from the same string and
12953 is empty. (Bug#9739) (Bug#9738)
12955 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
12957 * doc.c (get_doc_string): Encode file name (bug#9735).
12959 2011-10-12 Eli Zaretskii <eliz@gnu.org>
12961 * bidi.c (bidi_level_of_next_char):
12962 * xdisp.c (get_visually_first_element): Remove old incorrect
12963 comments regarding the Unicode Line Separator character.
12965 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
12967 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
12969 * alloc.c (Fgc_status): Do not access beyond zombies array
12970 boundary if nzombies > MAX_ZOMBIES.
12971 * alloc.c (dump_zombies): Add missing format specifier.
12973 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
12975 * xdisp.c (set_cursor_from_row): Simplify conditionals,
12976 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
12978 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
12979 Some packages use them to denote characters with modifiers.
12981 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
12983 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
12984 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
12985 matching a pp-number. Rename parameter var to var1.
12987 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
12989 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
12991 2011-10-08 Glenn Morris <rgm@gnu.org>
12993 * callint.c (Fcall_interactively): Give a more explicit error for the
12994 'c' case with a non-character input. (Bug#8479)
12996 2011-10-08 Eli Zaretskii <eliz@gnu.org>
12998 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
13000 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
13001 lines that are hscrolled on the left.
13003 * dispnew.c (buffer_posn_from_coords): Account for a possible
13004 presence of header-line. (Bug#4426)
13006 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
13008 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
13009 Don't advertise functionality which we discourage or doesn't work.
13011 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
13013 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
13014 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
13015 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
13016 this makes Emacs dump core during garbage collection on rare
13017 occasions. sizeof is obviously inferior to offsetof here, so
13018 stick with offsetof.
13019 (GC_POINTER_ALIGNMENT): New macro.
13020 (mark_memory): Omit 3rd (offset) arg; caller changed.
13021 Don't assume EMACS_INT alignment is the same as pointer alignment.
13023 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
13025 * keyboard.c (read_key_sequence_remapped): New var.
13026 (read_key_sequence): Compute remapping in the right buffer.
13027 (command_loop_1): Use read_key_sequence's remapping directly.
13029 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
13031 * dired.c (file_name_completion): Don't expand file name.
13032 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
13033 before checking file name handler.
13035 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
13036 they've been requested explicitly (bug#9591).
13038 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
13040 * keymap.c (Fsingle_key_description): Use make_specified_string
13041 instead of build_string to build string from push_key_description.
13044 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
13046 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
13047 This fixes a Y2038 bug on 64-bit hosts.
13048 * buffer.c (reset_buffer):
13049 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
13050 (Fclear_buffer_auto_save_failure):
13051 Use 0, not -1, to represent an unset failure time, since time_t
13052 might not be signed.
13054 Remove dependency on glibc malloc internals.
13055 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13056 Move back here from lisp.h, but with their new implementations.
13057 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13058 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
13059 * charset.c (charset_table_init): New static var.
13060 (syms_of_charset): Use it instead of xmalloc. This removes a
13061 dependency on glibc malloc internals. See Eli Zaretskii's comment in
13062 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
13063 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13064 Move back to alloc.c.
13065 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13066 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
13068 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
13070 * nsterm.m (windowDidResize): Call x_set_window_size only when
13071 ns_in_resize is true. Otherwise set pixelwidth/height and
13072 call change_frame_size (Bug#9628).
13074 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
13076 Port --enable-checking=all to Fedora 14 x86-64.
13077 * charset.c (syms_of_charset): Also account for glibc malloc's
13078 internal overhead when calculating the initial malloc maximum.
13080 Port --enable-checking=all to Fedora 14 x86.
13081 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13083 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
13084 (overrun_check_realloc, overrun_check_free):
13085 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
13086 That way, xmalloc returns a properly-aligned pointer even if
13087 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
13088 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
13089 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
13090 into account when calculating the initial malloc maximum.
13091 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13092 Move here from alloc.c, so that charset.c can use it too.
13093 Properly align; the old code wasn't right for common 32-bit hosts
13094 when configured with --enable-checking=all.
13095 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13096 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
13098 2011-09-29 Eli Zaretskii <eliz@gnu.org>
13100 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
13103 2011-09-28 Eli Zaretskii <eliz@gnu.org>
13105 * xdisp.c (compute_display_string_end): If there's no display
13106 string at CHARPOS, return -1.
13108 * bidi.c (bidi_fetch_char): When compute_display_string_end
13109 returns a negative value, treat the character as a normal
13110 character not covered by a display string. (Bug#9624)
13112 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
13114 * lread.c (Fread_from_string): Fix typo in docstring.
13116 2011-09-27 Eli Zaretskii <eliz@gnu.org>
13118 * xdisp.c (handle_invisible_prop): If invisible text ends on a
13119 newline, reseat the iterator instead of bidi-iterating there one
13120 character at a time. (Bug#9610)
13121 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
13122 TO_CHARPOS if the bidi iterator is at base embedding level.
13124 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
13126 * lread.c (readevalloop): Use correct code for NBSP.
13127 (read1): Likewise. (Bug#9608)
13129 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
13131 * dbusbind.c (Fdbus_register_signal): When service is not
13132 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
13134 2011-09-25 Glenn Morris <rgm@gnu.org>
13136 * buffer.c (truncate-lines): Doc fix.
13138 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
13140 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
13141 (Fset_window_next_buffers): Doc fix.
13143 2011-09-24 Glenn Morris <rgm@gnu.org>
13145 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
13147 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
13149 Fix minor problems found by static checking.
13150 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
13151 * indent.c (Fvertical_motion): Fix == vs = typo.
13153 2011-09-24 Eli Zaretskii <eliz@gnu.org>
13155 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
13156 Default value is now t. Doc fix.
13158 * indent.c (Fvertical_motion): Compute and apply the overshoot
13159 logic when moving up, not only when moving down. Fix the
13160 confusing name and values of the it_overshoot_expected variable;
13161 logic changes accordingly. (Bug#9254) (Bug#9549)
13163 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
13164 CHARPOS is covered by a display string which includes newlines.
13165 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
13166 is covered by a display string with embedded newlines.
13168 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
13170 * dbusbind.c (Fdbus_register_signal): Add match rule to
13171 Vdbus_registered_objects_table. (Bug#9581)
13172 (Fdbus_register_method, Vdbus_registered_objects_table):
13175 2011-09-24 Jim Meyering <meyering@redhat.com>
13177 do not ignore write error for any output size
13178 The previous change was incomplete.
13179 While it makes emacs --batch detect the vast majority of stdout
13180 write failures, errors were still ignored whenever the output size is
13181 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
13182 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
13183 && echo FAIL: ignored write error
13184 FAIL: ignored write error
13185 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
13186 && echo FAIL: ignored write error
13187 FAIL: ignored write error
13188 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
13190 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
13192 * emacs.c (Fkill_emacs): In noninteractive mode exit
13193 non-successfully if a write error occurred on stdout. (Bug#9574)
13195 2011-09-21 Eli Zaretskii <eliz@gnu.org>
13197 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
13200 * dispextern.h (struct it): Update the comment documenting what
13203 2011-09-20 Eli Zaretskii <eliz@gnu.org>
13205 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
13206 a display string, extend search for cursor position to end of row.
13207 (find_row_edges): If the row ends in a newline from a display
13208 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
13209 Handle the case of a display string with multiple newlines.
13210 (Fcurrent_bidi_paragraph_direction): Fix search for previous
13211 non-empty line. Fixes confusing cursor motion with arrow keys at
13212 the beginning of a line that starts with whitespace.
13214 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
13216 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
13219 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
13221 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
13222 boolean (Bug#9154).
13224 2011-09-18 Eli Zaretskii <eliz@gnu.org>
13226 * xdisp.c (display_line): Record maximum and minimum buffer
13227 positions even if no glyphs were produced (e.g., by a zero-width
13228 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
13229 buffer positions that will be removed from the glyph row because
13231 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
13232 column is beyond frame width: don't subtract 1 "pixel" when
13233 computing width of the stretch.
13234 (reseat_at_next_visible_line_start): Undo the change made on
13235 2011-09-17 that saved paragraph information and restored it after
13236 the call to `reseat'. (Bug#9545)
13238 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
13240 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
13241 and turn window cursor on if cleared (Bug#9415).
13243 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
13245 * search.c (boyer_moore): Take unibyte characters from pattern
13246 literally. (Bug#9458)
13248 2011-09-18 Eli Zaretskii <eliz@gnu.org>
13250 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
13252 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
13254 Fix minor problem found by static checking.
13255 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
13256 initialized, to pacify gcc -Wuninitialized.
13258 * fileio.c: Report proper errno when syscall falls.
13259 (Finsert_file_contents): Save and restore errno,
13260 so that report_file_error outputs the correct diagnostic.
13261 (Fwrite_region) [CLASH_DETECTION]: Likewise.
13263 2011-09-18 Eli Zaretskii <eliz@gnu.org>
13265 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
13267 2011-09-17 Eli Zaretskii <eliz@gnu.org>
13269 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
13270 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
13272 2011-09-17 Eli Zaretskii <eliz@gnu.org>
13274 * xdisp.c (reseat_at_next_visible_line_start): Keep information
13275 about the current paragraph and restore it after the call to reseat.
13277 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
13278 (bidi_find_paragraph_start): Search back for paragraph beginning
13279 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
13280 (bidi_move_to_visually_next): Only trigger paragraph-related
13281 computations when the last character is a newline or at EOB, not
13282 just any NEUTRAL_B. (Bug#9470)
13284 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
13285 truncated lines if point is covered by a display string. (Bug#9524)
13287 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
13289 * xselect.c: Relax test for outgoing X longs (Bug#9498).
13290 (cons_to_x_long): New function.
13291 (lisp_data_to_selection_data): Use it. Correct the test for
13292 short-versus-long data; it was negated. Break out of vector
13293 loop, for efficiency, when a long datum is discovered.
13295 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
13297 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
13299 2011-09-16 Eli Zaretskii <eliz@gnu.org>
13301 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
13302 GCC PR/17406) by declaring this function with external scope.
13304 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
13306 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
13307 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
13309 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
13311 * editfns.c (Fformat): Correctly handle text properties on "%%".
13313 2011-09-15 Eli Zaretskii <eliz@gnu.org>
13315 * xterm.c (x_draw_composite_glyph_string_foreground):
13316 * w32term.c (x_draw_composite_glyph_string_foreground):
13317 * term.c (encode_terminal_code):
13318 * composite.c (composition_update_it, get_composition_id):
13319 * xdisp.c (get_next_display_element)
13320 (fill_composite_glyph_string): Add comments about special meaning
13321 of TAB characters in a composition.
13323 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
13325 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
13326 This occurs when processing a multibyte format.
13327 Problem reported by Wolfgang Jenker.
13329 2011-09-15 Johan Bockgård <bojohan@gnu.org>
13331 * xdisp.c (try_cursor_movement): Only check for exact match if
13332 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
13334 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
13336 Remove unused external symbols.
13337 * dispextern.h (calc_pixel_width_or_height): Remove decl.
13338 * xdisp.c (calc_pixel_width_or_height): Now static.
13339 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
13340 * indent.c (check_display_width):
13341 * w32term.c: Fix comment to match code.
13342 * xterm.c, xterm.h (x_catching_errors): Remove.
13344 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
13346 * xselect.c: Use signed conversions more consistently (Bug#9498).
13347 (selection_data_to_lisp_data): Assume incoming selection data are
13348 signed integers, not unsigned. This is to be consistent with
13349 outgoing selection data, which was modified to use signed integers
13350 in as part of the fix to Bug#9196 in response to Jan D.'s comment
13351 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
13352 expects long, not unsigned long.
13354 2011-09-14 Eli Zaretskii <eliz@gnu.org>
13356 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
13357 computation of loop end. Reported by Johan Bockgård
13360 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
13362 * frame.c (Fother_visible_frames_p): Function deleted.
13364 2011-09-12 Eli Zaretskii <eliz@gnu.org>
13366 * indent.c (compute_motion): Process display vector front to back
13367 rather than the other way around. (Bug#2496)
13369 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
13371 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
13373 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
13375 * minibuf.c (Fread_from_minibuffer): Doc fix.
13377 2011-09-11 Eli Zaretskii <eliz@gnu.org>
13379 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
13380 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)

13385 value for non-existent files.
13387 2011-09-11 Eli Zaretskii <eliz@gnu.org>
13389 * fileio.c (Finsert_file_contents): If the file cannot be opened,
13390 set its "size" to -1. This will set the modtime_size field of
13391 the corresponding buffer to -1, which is what
13392 verify-visited-file-modtime expects for files that do not exist.
13395 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
13397 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
13399 * lisp.h: ... from here. push_key_description is no longer
13400 defined in keyboard.c, so its declaration should not be in
13401 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
13402 logically belongs with push_key_description.
13404 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
13406 * buffer.h: Include <sys/types.h> instead of <time.h>.
13407 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
13408 Problem reported by Herbert J. Skuhra.
13410 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
13412 * xml.c (parse_region): Make the parsing work for
13413 non-comment-starting XML files again (bug#9144).
13415 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
13417 * image.c (gif_load): Fix calculation of bottom and right corner.
13420 2011-09-10 Eli Zaretskii <eliz@gnu.org>
13422 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
13423 redisplay in small windows.
13425 2011-09-09 Eli Zaretskii <eliz@gnu.org>
13427 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
13429 2011-09-08 Martin Rudalics <rudalics@gmx.at>
13431 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
13432 Operate on live windows only.
13434 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
13436 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
13438 2011-09-07 Eli Zaretskii <eliz@gnu.org>
13440 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
13441 only under bidi iteration.
13443 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
13445 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
13447 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13449 isnan: Fix porting problem to Solaris 10 with bundled gcc.
13450 Without this fix, the command to link temacs failed due to an
13451 undefined symbol __builtin_isnan. This is because
13452 /usr/include/iso/math_c99.h #defines isnan(x) to
13453 __builtin_isnan(x), but the bundled gcc, which identifies itself
13454 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
13456 * floatfns.c (isnan): #undef, and then #define to a clone of
13458 (Fisnan): Always define, since it's always available now.
13459 (syms_of_floatfns): Always define isnan at the Lisp level.
13461 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13463 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
13465 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13467 * fileio.c: Fix bugs with large file offsets (Bug#9428).
13468 The previous code assumed that file offsets (off_t values) fit in
13469 EMACS_INT variables, which is not true on typical 32-bit hosts.
13470 The code messed up by falsely reporting buffer overflow in cases
13471 such as (insert-file-contents "big" nil 1 2) into an empty buffer
13472 when "big" contains more than 2**29 bytes, even though this
13473 inserts just one byte and does not overflow the buffer.
13474 (Finsert_file_contents): Store file offsets as off_t
13475 values, not as EMACS_INT values. Check for overflow when
13476 converting between EMACS_INT and off_t. When checking for
13477 buffer overflow or for overlap, take the offsets into account.
13478 Don't use EMACS_INT for small values where int suffices.
13479 When checking for overlap, fix a typo: ZV was used where
13480 ZV_BYTE was intended.
13481 (Fwrite_region): Don't assume off_t fits into 'long'.
13482 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
13484 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
13486 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
13488 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
13490 sprintf-related integer and memory overflow issues (Bug#9412).
13492 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
13493 (esprintf, exprintf, evxprintf): New functions.
13494 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
13495 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
13496 (modify_event_symbol): Do not assume that the length of
13497 name_alist_or_stem is safe to alloca and fits in int.
13498 (Fexecute_extended_command): Likewise for function name and binding.
13499 (Frecursion_depth): Wrap around reliably on integer overflow.
13500 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
13501 since some callers pass EMACS_INT values.
13502 (Fsingle_key_description): Don't crash if symbol name contains more
13503 than MAX_ALLOCA bytes.
13504 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
13505 (get_minibuffer): Arg is now EMACS_INT, not int.
13506 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
13507 (esprintf, exprintf, evxprintf): New decls.
13508 * window.h (command_loop_level, minibuf_level): Reflect API changes.
13510 * dbusbind.c (signature_cat): New function.
13511 (xd_signature, Fdbus_register_signal):
13512 Do not overrun buffer; instead, report string overflow.
13514 * dispnew.c (add_window_display_history): Don't overrun buffer.
13515 Truncate instead; this is OK since it's just a log.
13517 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
13518 even if the time zone offset is outlandishly large.
13519 Don't mishandle offset == INT_MIN.
13521 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
13522 when creating daemon; the previous buffer-overflow check was incorrect.
13524 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
13525 which has the guts of the old verror function.
13527 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
13528 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
13530 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
13531 (font_unparse_xlfd): Don't blindly alloca long strings.
13532 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
13533 fits in int, when using sprintf. Use single snprintf to count
13534 length of string rather than counting it via multiple sprintfs;
13535 that's simpler and more reliable.
13536 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
13537 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
13538 sprintf, in case result does not fit in int.
13540 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
13541 (fontset_from_font): Print it.
13543 * frame.c (tty_frame_count): Now printmax_t, not int.
13544 (make_terminal_frame, set_term_frame_name): Print it.
13545 (x_report_frame_params): In X, window IDs are unsigned long,
13546 not signed long, so print them as unsigned.
13547 (validate_x_resource_name): Check for implausibly long names,
13548 and don't assume name length fits in 'int'.
13549 (x_get_resource_string): Don't blindly alloca invocation name;
13550 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
13553 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
13554 (xg_check_special_colors, xg_set_geometry):
13555 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
13557 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
13558 Use esprintf, not sprintf, in case result does not fit in int.
13560 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
13561 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
13562 it as a large positive number.
13563 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
13564 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
13566 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
13567 in case result does not fit in int.
13569 * print.c (float_to_string): Detect width overflow more reliably.
13570 (print_object): Make sprintf buffer a bit bigger, to avoid potential
13571 buffer overrun. Don't assume list length fits in 'int'. Treat
13572 print length of 0 as 0, not as infinity; to be consistent with other
13573 uses of print length in this function. Don't overflow print length
13574 index. Don't assume hash table size fits in 'long', or that
13575 vectorlike size fits in 'unsigned long'.
13577 * process.c (make_process): Use printmax_t, not int, to format
13578 process-name gensyms.
13580 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
13582 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
13583 to avoid potential buffer overrun.
13585 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
13586 if X resource line is longer than 512 bytes.
13588 * xfns.c (x_window): Make sprintf buffer a bit bigger
13589 to avoid potential buffer overrun.
13591 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
13593 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
13595 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
13597 Integer overflow fixes for scrolling, etc.
13598 Without these, Emacs silently mishandles large integers sometimes.
13599 For example, "C-u 4294967297 M-x recenter" was treated as if
13600 it were "C-u 1 M-x recenter" on a typical 64-bit host.
13602 * xdisp.c (try_window_id): Check Emacs fixnum range before
13603 converting to 'int'.
13605 * window.c (window_scroll_line_based, Frecenter):
13606 Check that an Emacs fixnum is in range before assigning it to 'int'.
13607 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
13608 values converted from Emacs fixnums.
13609 (Frecenter): Don't wrap around a line count if it is out of 'int'
13610 range; instead, treat it as an extreme value.
13611 (Fset_window_configuration, compare_window_configurations):
13612 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
13614 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
13615 that can exceed INT_MAX. Check that EMACS_INT value is in range
13616 before assigning it to the (possibly-narrower) index.
13617 (match_limit): Don't assume that a fixnum can fit in 'int'.
13619 * print.c (print_object): Use ptrdiff_t, not int, for index that can
13622 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
13623 (Fvertical_motion): Don't wrap around LINES values that don't fit
13624 in 'int'. Instead, treat them as extreme values. This is good
13625 enough for windows, which can't have more than INT_MAX lines anyway.
13627 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
13629 * Require libxml/parser.h to avoid compilation warning.
13631 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
13633 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
13634 since this reportedly can destroy thread storage.
13636 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
13638 * syntax.c (find_defun_start): Update all cache variables if
13639 exiting early (Bug#9401).
13641 2011-08-30 Eli Zaretskii <eliz@gnu.org>
13643 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
13645 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
13646 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
13647 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
13649 * term.c (tty_append_glyph): New function.
13650 (produce_stretch_glyph): Static function and its prototype deleted.
13652 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
13655 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
13657 * image.c (parse_image_spec): Check for nonnegative, not for positive,
13658 when checking :margin (Bug#9390).
13659 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
13660 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
13661 so that the name doesn't mislead. All uses changed.
13663 2011-08-28 Johan Bockgård <bojohan@gnu.org>
13665 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
13668 2011-08-27 Eli Zaretskii <eliz@gnu.org>
13670 * xdisp.c (move_it_to): Don't bail out early when reaching
13671 position beyond to_charpos, if we are scanning backwards.
13672 (move_it_vertically_backward): When DY == 0, make sure we get to
13673 the first character in the line after the newline.
13675 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
13677 * ccl.c: Improve and simplify overflow checking (Bug#9196).
13678 (ccl_driver): Do not generate an out-of-range pointer.
13679 (Fccl_execute_on_string): Remove unnecessary check for
13680 integer overflow, noted by Stefan Monnier in
13681 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
13682 Remove a FIXME that didn't need fixing.
13683 Simplify the newly-introduced buffer reallocation code.
13685 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
13687 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
13689 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
13691 Integer and memory overflow issues (Bug#9196).
13693 * doc.c (get_doc_string): Rework so that
13694 get_doc_string_buffer_size is the actual buffer size, rather than
13695 being 1 less than the actual buffer size; this makes xpalloc more
13698 * image.c (x_allocate_bitmap_record, cache_image):
13699 * xselect.c (Fx_register_dnd_atom):
13700 Simplify previous changes by using xpalloc.
13702 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
13703 since either will do and ptrdiff_t is convenient with xpalloc.
13705 * charset.c (charset_table_size)
13706 (struct charset_sort_data.priority): Now ptrdiff_t.
13707 (charset_compare): Don't overflow if priorities differ greatly.
13708 (Fsort_charsets): Don't assume list length fits in int.
13709 Check for size-calculation overflow when allocating sort data.
13710 (syms_of_charset): Allocate an initial charset table that is
13711 just under 64 KiB, to avoid problems with glibc malloc and mmap.
13713 * cmds.c (internal_self_insert): Check for size-calculation overflow.
13715 * composite.h (struct composition.glyph_len): Now int, not unsigned.
13716 The actual value is always <= INT_MAX, and leaving it unsigned made
13717 overflow checking harder.
13719 * dispextern.h (struct glyph_matrix.rows_allocated)
13720 (struct face_cache.size): Now ptrdiff_t, for convenience in use
13721 with xpalloc. The values are still always <= INT_MAX.
13723 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
13725 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
13726 (SAFE_NALLOCA): New macro.
13728 * region-cache.c (struct boundary.pos, find_cache_boundary)
13729 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
13730 (set_cache_region, invalidate_region_cache)
13731 (revalidate_region_cache, know_region_cache, region_cache_forward)
13732 (region_cache_backward, pp_cache):
13733 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
13734 so that ptrdiff_t * can be passed to xpalloc.
13735 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
13736 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
13737 (pp_cache): Don't assume cache_len fits in int.
13738 * region-cache.h: Adjust extern decls to match.
13740 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
13741 EMACS_INT, since either will do, for xpalloc.
13743 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
13744 (xnmalloc, xnrealloc, xpalloc): New functions.
13746 * bidi.c (bidi_shelve_header_size): New constant.
13747 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
13748 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
13750 * bidi.c (bidi_cache_shrink):
13751 * buffer.c (overlays_at, overlays_in, record_overlay_string)
13753 Don't update size of array until after memory allocation succeeds,
13754 because xmalloc/xrealloc may not return.
13755 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
13756 now that we have proper integer overflow checking.
13757 (record_overlay_string, overlay_strings): Catch overflows when
13758 calculating size of overlay_str_buf.
13760 * callproc.c (Fcall_process): Check for size overflow when
13761 calculating size of args2.
13762 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
13763 Normally we prefer signed values, but sticking with ptrdiff_t would
13764 require adding more-complicated checks.
13766 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
13767 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
13768 Redo buffer-overflow calculations to avoid integer overflow.
13769 Add a FIXME comment where memory seems to be over-allocated.
13771 * character.c (Fstring): Check for size-calculation overflow.
13773 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
13774 unnecessary integer overflow. Check for size overflow.
13775 (encode_coding_object): Don't update size until xmalloc succeeds.
13777 * composite.c (get_composition_id): Check for overflow in glyph
13778 length calculations.
13780 Integer and memory overflow fixes for display code.
13781 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
13782 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
13783 (scrolling_window): Check for overflow in size calculations.
13784 (line_draw_cost, realloc_glyph_pool, add_row_entry):
13785 Don't assume glyph table len fits in int.
13786 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
13787 (row_table_size): Now ptrdiff_t, not int.
13788 (scrolling_window): Avoid overflow in size calculations.
13789 Don't update size until allocation succeeds.
13790 * fns.c (concat): Check for overflow in size calculations.
13791 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
13792 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
13793 (NEXT_ALMOST_PRIME_LIMIT): New constant.
13795 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
13796 (get_doc_string): Check for size calculation overflow.
13797 Don't update size until allocation succeeds.
13798 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
13799 EMACS_INT, where ptrdiff_t will do.
13800 (Fsubstitute_command_keys): Check for string overflow.
13802 * editfns.c (set_time_zone_rule): Don't assume environment length
13804 (message_length): Now ptrdiff_t, not int.
13805 (Fmessage_box): Don't update size until allocation succeeds.
13806 Don't assume message length fits in int.
13807 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
13809 * emacs.c (main): Do not reallocate argv, since there is a null at
13810 the end that can be overwritten, and this way there's no need to
13811 worry about size-calculation overflow.
13812 (sort_args): Check for size-calculation overflow.
13814 * eval.c (init_eval_once, grow_specpdl): Don't update size until
13816 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
13818 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
13819 (x_set_scroll_bar_width, x_figure_window_size):
13820 Check for integer overflow.
13821 (x_set_alpha): Do not assume XINT fits in int.
13823 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
13824 This is for the members text_lines, text_cols, total_lines, total_cols,
13825 where the system imposes an 'int' limit.
13827 * fringe.c (Fdefine_fringe_bitmap):
13828 Don't update size until alloc works.
13830 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
13831 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
13833 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
13834 Check for size-calculation overflow.
13835 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
13836 do, as we prefer signed integers.
13837 (id_to_widget.max_size, id_to_widget.used)
13838 (xg_store_widget_in_map, xg_remove_widget_from_map)
13839 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
13840 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
13841 Use and return ptrdiff_t, not int.
13842 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
13843 * gtkutil.h: Change prototypes to match the above.
13845 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
13846 are duplicate now that they've been promoted to lisp.h.
13847 (x_allocate_bitmap_record, x_alloc_image_color)
13848 (make_image_cache, cache_image, xpm_load):
13849 Don't update size until alloc is done.

13890 (Fset_match_data): Don't assume list lengths fit in 'int'.
13892 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
13893 for command line length. Do not attempt to address one before the
13894 beginning of an array, as that's not portable.
13896 * term.c (max_frame_lines): Remove; unused.

13924 Check for size calculation overflow.
13925 (cache_face): Treat size calculation overflows as if they were
13926 memory exhaustion (the usual treatment), rather than aborting.
13928 * xfns.c (x_encode_text, x_set_name_internal)
13929 (Fx_change_window_property): Use ptrdiff_t, not int, to count
13930 sizes, since they can exceed INT_MAX in size. Check for size
13931 calculation overflow.
13933 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
13934 (xg_select): Check for size calculation overflow.
13935 Don't update size until alloc done.
13937 * xrdb.c (get_environ_db): Don't assume path length fits in int,
13938 as sprintf is limited to int lengths.
13940 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
13941 (X_LONG_MIN): New macros.
13942 Use them to make the following changes clearer.
13943 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
13944 This change doesn't affect the value now, but it may help remind
13945 future maintainers not to raise the value too much later.
13946 (SELECTION_QUANTUM): Remove, replacing with ...
13947 (selection_quantum): ... new function, which avoids overflow.
13949 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
13950 assumption that selection length fits in 'int'.

13967 Don't store size until memory allocation succeeds.
13968 (x_get_window_property): Plug memory leak on memory exhaustion.
13969 Don't double-block input; malloc is safe here. Don't assume 2**34
13970 - 4 fits in unsigned long. Add an xassert to check
13971 XGetWindowProperty overflow. Be more careful about overflow
13972 calculations, and distinguish size from memory overflow better.
13973 (receive_incremental_selection): When tracing, don't assume
13974 unsigned int is less than INT_MAX.
13975 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory

13979 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
13980 result parameters unless successful. Rely on cons_to_unsigned
13981 to report problems with elements; the old code wasn't right anyway.
13982 (x_check_property_data): Check for int overflow; we cannot use
13983 a wider type due to X limits.

14016 * lisp.h (hash_lookup, hash_put):
14017 * minibuf.c (Ftest_completion):
14018 Use ptrdiff_t for hash table indexes, not int (which is too
14019 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
14020 32-bit --with-wide-int hosts).
14022 * charset.c (Fdefine_charset_internal): Check for integer overflow.
14023 Add a FIXME comment about memory leaks.

14031 with outlandish widths.
14032 * character.h (sanitize_tab_width): Rename from sanitize_width,
14033 now that we have two such functions. All uses changed.

14051 * xterm.c: Don't go over XClientMessageEvent limit.
14052 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
14053 (x_send_scroll_bar_event): Likewise. Check that the size does not
14054 exceed limits imposed by XClientMessageEvent, as well as the usual
14055 ptrdiff_t and size_t limits.
14057 * keyboard.c: Overflow, signedness and related fixes.
14058 (make_lispy_movement): Use same integer type in forward decl
14059 that is used in the definition.
14060 (read_key_sequence, keyremap_step):
14061 Change bufsize argument back to int, undoing my 2011-03-30 change.
14062 We prefer signed types, and int is wide enough here.
14063 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
14064 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
14065 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
14066 length, not size_t. Use ptrdiff_t for index, not int.
14067 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
14068 possibility of integer overflow.

14096 Prefer int to unsigned where either will do.
14097 (tiff_handler): New function, combining the cores of the
14098 old tiff_error_handler and tiff_warning_handler.
14099 This function is rewritten to use vsnprintf and thereby avoid
14100 stack buffer overflows. It uses only the features of vsnprintf
14101 that are common to both POSIX and native Microsoft.
14102 (tiff_error_handler, tiff_warning_handler): Use it.
14103 (tiff_load, gif_load, imagemagick_load_image):
14104 Don't assume :index value fits in 'int'.
14105 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
14106 (imagemagick_load_image): Check that crop parameters fit into
14107 the integer types that MagickCropImage accepts. Don't assume
14108 Vimagemagick_render_type has a nonnegative value. Don't assume
14109 size_t fits in 'long'.
14110 (gs_load): Use printmax_t to print the widest integers possible.

14124 (handle_single_display_spec): If the display spec is of the form
14125 `(space ...)', and specifies display in the text area, return 2
14127 (try_cursor_movement): Check for the need to scroll more

14147 buffers, return left-to-right.
14148 (set_cursor_from_row): Consider candidate row a win if its glyph
14149 represents a newline and point is on that newline. Fixes cursor
14150 positioning on the newline at EOL of R2L text within L2R
14151 paragraph, and vice versa.
14152 (try_cursor_movement): Check continued rows, in addition to
14153 continuation rows. Fixes unwarranted scroll when point enters a
14154 continued line of R2L text within an L2R paragraph, or vice versa.
14155 (cursor_row_p): Consider the case of point being equal to
14156 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving

14185 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
14186 instead of CHAR_TO_BYTE. Fixes a crash when a completion
14187 candidate is selected by the mouse, and that candidate has a
14188 composed character under the mouse.
14190 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
14191 coordinates reported by pos-visible-in-window-p for a composed
14192 character in column zero.

14200 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
14201 consider it a hit if to_charpos is anywhere in the range of the
14202 composed buffer positions.
14204 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
14206 * image.c (gif_load): Don't assume that each subimage has the same
14207 dimensions as the base image. Handle disposal method that is
14208 "undefined" by the gif spec (Bug#9335).
14210 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
14212 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

14222 a composition, take its buffer position from IT->cmp_it.charpos.
14223 Fixes cursor positioning at the beginning of a line that begins
14224 with a composed character.
14226 2011-08-18 Eli Zaretskii <eliz@gnu.org>
14228 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
14229 character bidirectional type, use STRONG_L instead. Fixes crashes
14230 in a buffer produced by `describe-categories'.
14232 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
14233 members before the level stack, so they would be saved and
14234 restored when copying iterator state. Fixes incorrect reordering
14235 around TABs covered by display properties.
14237 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>

14296 biditype.h and bidimirror.h.
14298 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
14299 coordinates of the iterator when restoring from ppos_it.
14302 2011-08-14 Kenichi Handa <handa@m17n.org>
14304 * process.c (create_process): Call setup_process_coding_systems
14305 after the pid of the process is set to -1 (Bug#8162).
14307 2011-08-14 Eli Zaretskii <eliz@gnu.org>
14309 * xdisp.c (move_it_in_display_line_to): Don't invoke
14310 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
14311 ppos_it. Fixes vertical cursor motion when line beginning is
14312 covered by an image. (Bug#9296)
14314 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
14316 * nsterm.h (ns_run_ascript): Declare.
14317 (NSAPP_DATA2_RUNASSCRIPT): Define.
14319 * nsfns.m (as_script, as_result, as_status): New static variables.
14320 (ns_run_ascript): New function.
14321 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
14322 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
14323 the event loop. Get status from as_status (Bug#7276).
14325 * nsterm.m (sendEvent): If event is NSApplicationDefined and
14326 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
14327 the event loop (Bug#7276).
14329 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
14331 * gnutls.c (QCgnutls_bootprop_priority)
14332 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
14333 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
14334 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
14335 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
14336 (QCgnutls_bootprop_verify_hostname_error)
14337 (QCgnutls_bootprop_callbacks_verify): Rename from
14338 Qgnutls_bootprop_..., all uses changed.
14340 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
14343 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
14345 * xfaces.c (Qframe_set_background_mode): Now static.
14346 * dispextern.h (Qframe_set_background_mode): Remove decl.
14348 * process.c (Fnetwork_interface_info): Declare local only if needed.
14350 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
14352 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
14353 (Fnetwork_interface_list): Allocate in increments of bytes instead
14354 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
14355 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
14357 (struct ifflag_def): notrailers is smart on OSX.
14358 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
14359 Get hardware address with getifaddrs if available.
14361 2011-08-12 Eli Zaretskii <eliz@gnu.org>
14363 * xdisp.c (iterate_out_of_display_property): xassert that
14364 IT->position is set to within IT->object's boundaries. Break from
14365 the loop as soon as EOB is reached; avoids infloops in redisplay
14366 when IT->position is set up wrongly due to some bug.
14367 Set IT->current to match the bidi iterator unconditionally.
14368 (push_display_prop): Allow GET_FROM_STRING as IT->method on
14369 entry. Force push_it to save on the stack the current
14370 buffer/string position, to be restored by pop_it. Fix flags in
14371 the iterator structure wrt the object coming from a display
14372 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
14373 properties. (Bug#9284)
14375 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
14377 * fontset.c (fontset_get_font_group): Add proper type checks.
14380 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14382 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
14383 and LC_VERSION_MIN_MACOSX.
14384 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
14385 (dump_it) [LC_FUNCTION_STARTS]: Use it.
14387 2011-08-08 Eli Zaretskii <eliz@gnu.org>
14389 * xdisp.c (forward_to_next_line_start): Allow to use the
14390 no-display-properties-and-no-overlays under bidi display.
14391 Set disp_pos in the bidi iterator to avoid searches for display
14392 properties and overlays.
14394 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
14396 * editfns.c (Fset_time_zone_rule): Document relationship with the
14399 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
14400 the font entity extracted from the cache (Bug#8109).
14402 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
14404 * composite.c (autocmp_chars): Don't reset point. That is done by
14405 restore_point_unwind (Bug#5984).
14407 2011-08-07 Juri Linkov <juri@jurta.org>
14409 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
14410 to show the arg `TIME' instead of `TIMEVAL'.
14412 2011-08-06 Eli Zaretskii <eliz@gnu.org>
14414 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
14415 display property strides EOL and includes a newline, as in
14416 longlines-mode. (Bug#9254)
14417 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
14418 word-wrap under bidirectional display. (Bug#9224)
14420 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
14421 is non-zero, even if the data buffer is NULL. Fixes a crash in
14422 vertical-motion with longlines-mode. (Bug#9254)
14424 2011-08-05 Eli Zaretskii <eliz@gnu.org>
14426 * bidi.c <bidi_cache_total_alloc>: Now static.
14427 (bidi_initialize): Initialize bidi_cache_total_alloc.
14429 * xdisp.c (display_line): Release buffer allocated for shelved bidi
14432 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
14433 amount allocated this far in `bidi_cache_total_alloc'.
14434 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
14435 non-zero, only free the data buffer without restoring the cache
14436 contents. All callers changed.
14438 * dispextern.h (bidi_unshelve_cache): Update prototype.
14440 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
14441 (move_it_in_display_line, move_it_to)
14442 (move_it_vertically_backward, move_it_by_lines): Replace the call
14443 to xfree to an equivalent call to bidi_unshelve_cache.
14444 (move_it_in_display_line_to): Fix logic of returning
14445 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
14447 2011-08-05 Eli Zaretskii <eliz@gnu.org>
14449 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
14450 came from a string character with a `cursor' property. (Bug#9229)
14452 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
14454 * Makefile.in (LIB_PTHREAD): New variable.
14455 (LIBES): Add LIB_PTHREAD (Bug#9216).
14457 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
14458 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
14460 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
14462 * regex.c (re_iswctype): Remove some redundant boolean conversions.
14464 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
14466 * xterm.c (x_find_topmost_parent): New function.
14467 (x_set_frame_alpha): Find topmost parent window with
14468 x_find_topmost_parent and set the property there also (bug#9181).
14469 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
14471 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
14473 * callproc.c (Fcall_process): Avoid vfork clobbering
14474 the local vars buffer, coding_systems, current_dir.
14476 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
14478 * keymap.c (Fmake_composed_keymap): Move to subr.el.
14480 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
14482 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
14483 so that it is not optimized away.
14485 * xdisp.c (compute_display_string_pos): Remove unused local.
14487 2011-08-02 Eli Zaretskii <eliz@gnu.org>
14489 Fix slow cursor motion and scrolling in large buffers with
14490 selective display, like Org Mode buffers. (Bug#9218)
14492 * dispextern.h (struct bidi_it): New member disp_prop_p.
14494 * xdisp.c: Remove one-slot cache of display string positions.
14495 (compute_display_string_pos): Accept an additional argument
14496 DISP_PROP_P; callers changed. Scan at most 5K characters forward
14497 for a display string or property. If found, set DISP_PROP_P
14500 * bidi.c (bidi_fetch_char): Accept an additional argument
14501 DISP_PROP_P, and pass it to compute_display_string_pos.
14502 Only handle text covered by a display string if DISP_PROP_P is returned
14503 non-zero. All callers of bidi_fetch_char changed.
14505 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
14507 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
14509 2010-12-03 Don March <don@ohspite.net>
14511 * keymap.c (Fdefine_key): Fix non-prefix key error message when
14512 last character M-[char] is translated to ESC [char] (bug#7541).
14514 2011-08-02 Kenichi Handa <handa@m17n.org>
14516 * lisp.h (uniprop_table): Extern it.
14518 * chartab.c (uniprop_table): Make it non-static.
14520 2011-08-01 Eli Zaretskii <eliz@gnu.org>
14522 * xdisp.c (forward_to_next_line_start): Accept additional argument
14523 BIDI_IT_PREV, and store into it the state of the bidi iterator had
14525 (reseat_at_next_visible_line_start): Use the bidi iterator state
14526 returned by forward_to_next_line_start to restore the state of
14527 it->bidi_it after backing up to previous newline. (Bug#9212)
14529 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
14531 * regex.c (re_comp): Protoize.
14532 (re_exec): Fix return type.
14533 (regexec): Fix type of `ret'. (Bug#9203)
14535 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14537 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
14538 This is needed if max-image-size is a floating-point number.
14540 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
14542 * print.c (print_object): Print empty symbol as ##.
14544 * lread.c (read1): Read ## as empty symbol.
14546 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
14548 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
14549 setting frame foreground color (Bug#9175).
14550 (x_set_background_color): Likewise.
14552 * nsmenu.m (-setText): Size tooltip dimensions precisely to
14553 contents (Bug#9176).
14554 (EmacsTooltip -init): Remove bezels and add shadows to
14557 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
14558 or scroll bar (Bug#8470).
14560 * nsfont.m (nsfont_open): Remove assignment to voffset and
14561 unnecessary vars hshink, expand, hd, full_height, min_height.
14562 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
14564 * nsterm.h (nsfont_info): Remove voffset field.
14566 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
14568 Implement strike-through and overline on NextStep (Bug#8863).
14570 * nsfont.m (nsfont_open): Use underline position provided by font,
14571 instead of hard-coded value of 2.
14572 (nsfont_draw): Call ns_draw_text_decoration instead.
14574 * nsterm.h: Add declaration for ns_draw_text_decoration.
14576 * nsterm.m (ns_draw_text_decoration): New function for drawing
14577 underline, overline, and strike-through.
14578 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
14579 ns_draw_text_decoration. Change treatment of cursor drawing to
14580 accommodate underlining, etc.
14582 2011-07-28 Eli Zaretskii <eliz@gnu.org>
14584 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
14587 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14589 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
14590 Without this fix, if a signal arrives just after memory fills up,
14591 'malloc' might be invoked reentrantly.
14593 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
14594 In other words, assume that every image size is allowed, on non-X
14595 hosts. This assumption is probably wrong, but it lets Emacs compile.
14597 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
14599 * regex.c (re_iswctype): Convert return values to boolean.
14601 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
14603 * xdisp.c (compute_display_string_pos): Don't use cached display
14604 string position if the buffer had its restriction changed.
14607 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14609 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
14611 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14613 Integer signedness and overflow and related fixes. (Bug#9079)
14615 * bidi.c: Integer size and overflow fixes.
14616 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
14617 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
14618 (bidi_cache_find_level_change, bidi_cache_ensure_space)
14619 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
14620 (bidi_find_other_level_edge):
14621 Use ptrdiff_t instead of EMACS_INT where either will do.
14622 This works better on 32-bit hosts configured --with-wide-int.
14623 (bidi_cache_ensure_space): Check for size-calculation overflow.
14624 Use % rather than repeated addition, for better worst-case speed.
14625 Don't set bidi_cache_size until after xrealloc returns, because it
14627 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
14628 (bidi_cache_ensure_space): Also check that the bidi cache size
14629 does not exceed that of the largest Lisp string or buffer. See Eli
14630 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
14632 * alloc.c (__malloc_size_t): Remove.
14633 All uses replaced by size_t. See Andreas Schwab's note
14634 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
14636 * image.c: Improve checking for integer overflow.
14637 (check_image_size): Assume that f is nonnull, since
14638 it is always nonnull in practice. This is one less thing to
14639 worry about when checking for integer overflow later.
14640 (x_check_image_size): New function, which checks for integer
14641 overflow issues inside X.
14642 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
14643 This removes the need for a memory_full check.
14644 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
14645 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
14646 (xbm_read_bitmap_data): Change locals back to 'int', since
14647 their values must fit in 'int'.
14648 (xpm_load_image, png_load, tiff_load):
14649 Invoke x_create_x_image_and_pixmap earlier,
14650 to avoid much needless work if the image is too large.
14651 (tiff_load): Treat overly large images as if
14652 x_create_x_image_and_pixmap failed, not as malloc failures.
14653 (gs_load): Use x_check_image_size.
14655 * gtkutil.c: Omit integer casts.
14656 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
14657 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
14659 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
14661 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
14662 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
14663 would wrongly return t on a 64-bit host.
14665 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
14666 The plain *_OVERFLOW macros run afoul of GCC bug 49705
14667 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
14668 and therefore cause GCC to emit a bogus diagnostic in some cases.
14670 * image.c: Integer signedness and overflow and related fixes.
14671 This is not an exhaustive set of fixes, but it's time to
14672 record what I've got.
14673 (lookup_pixel_color, check_image_size): Remove redundant decls.
14674 (check_image_size): Don't assume that arbitrary EMACS_INT values
14675 fit in 'int', or that arbitrary 'double' values fit in 'int'.
14676 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
14677 (tiff_load, imagemagick_load_image):
14678 Check for overflow in size calculations.
14679 (x_create_x_image_and_pixmap): Remove unnecessary test for
14680 xmalloc returning NULL; that can't happen.
14681 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
14682 (xpm_color_bucket): Use better integer hashing function.
14683 (xpm_cache_color): Don't possibly over-allocate memory.
14684 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
14685 (gif_memory_source):
14686 Use ptrdiff_t, not int or size_t, to record sizes.
14687 (png_load): Don't assume values greater than 2**31 fit in 'int'.
14688 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
14689 either works, as we prefer signed integers.
14690 (tiff_read_from_memory, tiff_write_from_memory):
14691 Return tsize_t, not size_t, since that's what the TIFF API wants.
14692 (tiff_read_from_memory): Don't fail simply because the read would
14693 go past EOF; instead, return a short read.
14694 (tiff_load): Omit no-longer-needed casts.
14695 (Fimagemagick_types): Don't assume size fits into 'int'.
14697 Improve hashing quality when configured --with-wide-int.
14698 * fns.c (hash_string): New function, taken from sxhash_string.
14699 Do not discard information about ASCII character case; this
14700 discarding is no longer needed.
14701 (sxhash-string): Use it. Change sig to match it. Caller changed.
14702 * lisp.h: Declare it.
14703 * lread.c (hash_string): Remove, since we now use fns.c's version.
14704 The fns.c version returns a wider integer if --with-wide-int is
14705 specified, so this should help the quality of the hashing a bit.
14707 * emacs.c: Integer overflow minor fix.
14708 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
14709 Define only if GNU_LINUX.
14710 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
14712 * dispnew.c: Integer signedness and overflow fixes.
14713 Remove unnecessary forward decls, that were a maintenance hassle.
14714 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
14716 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
14717 (scrolling_window): Use ptrdiff_t, not int, for byte count.
14718 (prepare_desired_row, line_draw_cost):
14719 Use int, not unsigned, where either works.
14720 (save_current_matrix, restore_current_matrix):
14721 Use ptrdiff_t, not size_t, where either works.
14722 (init_display): Check for overflow more accurately, and without
14723 relying on undefined behavior.
14725 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
14726 Remove, replacing with the new symbols in lisp.h. All uses changed.
14727 * fileio.c (make_temp_name):
14728 * filelock.c (lock_file_1, lock_file):
14729 * xdisp.c (message_dolog):
14730 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
14731 Use pMd etc. instead.
14732 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
14733 replacing the pWIDE etc. symbols removed from editfns.c.
14735 * keyboard.h (num_input_events): Now uintmax_t.
14736 This is (very slightly) less likely to mess up due to wraparound.
14739 * buffer.c: Integer signedness fixes.
14740 (alloc_buffer_text, enlarge_buffer_text):
14741 Use ptrdiff_t rather than size_t when either will do, as we prefer
14744 * alloc.c: Integer signedness and overflow fixes.
14745 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
14746 (__malloc_size_t): Default to size_t, not to int.
14747 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
14748 (Fgarbage_collect, mark_object_loop_halt, mark_object):
14749 Prefer ptrdiff_t to size_t when either would do, as we prefer
14751 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
14752 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
14753 Now const. Initialize with values that are in range even if char
14755 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
14756 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
14757 These functions do the right thing with sizes > 2**32.
14758 (check_depth): Now ptrdiff_t, not int.
14759 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
14760 Adjust to new way of storing sizes. Check for size overflow bugs
14762 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
14763 slightly wrong anyway, as it missed one instance of
14764 XMALLOC_OVERRUN_CHECK_OVERHEAD.
14765 (refill_memory_reserve): Omit needless cast to size_t.
14766 (mark_object_loop_halt): Mark as externally visible.
14768 * xselect.c: Integer signedness and overflow fixes.
14769 (Fx_register_dnd_atom, x_handle_dnd_message):
14770 Use ptrdiff_t, not size_t, since we prefer signed.
14771 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
14772 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
14773 x_dnd_atoms_size and x_dnd_atoms_length.
14775 * doprnt.c: Prefer signed to unsigned when either works.
14777 * doprnt.c (doprnt):
14779 * xdisp.c (vmessage):
14780 Use ptrdiff_t, not size_t, when using or implementing doprnt,
14781 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
14782 prefer signed arithmetic to avoid comparison confusion.
14783 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
14784 but is a bit tricky.
14786 Assume freestanding C89 headers, string.h, stdlib.h.
14787 * data.c, doprnt.c, floatfns.c, print.c:
14788 Include float.h unconditionally.
14789 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
14790 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
14791 * regex.c: Likewise for stddef.h, string.h.
14792 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
14793 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
14794 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
14795 (STDC_HEADERS): Remove obsolete defines.
14796 * sysdep.c: Include limits.h unconditionally.
14798 Assume support for memcmp, memcpy, memmove, memset.
14799 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
14800 * regex.c (memcmp, memcpy):
14801 Remove; we assume C89 now.
14803 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
14804 (__malloc_safe_bcopy): Remove; no longer needed.
14806 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
14807 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
14808 well either way, and we prefer signed to unsigned.
14810 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
14812 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
14813 closes the connection while we're reading (bug#9182).
14815 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
14817 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
14818 are specified (Bug#9168).
14820 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
14822 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
14823 Found by GCC static checking and --with-wide-int on a 32-bit host.
14825 2011-07-25 Eli Zaretskii <eliz@gnu.org>
14827 * xdisp.c (compute_display_string_pos): Fix logic of caching
14828 previous display string position. Initialize cached_prev_pos to
14829 -1. Fixes slow-down at the beginning of a buffer.
14831 2011-07-24 Eli Zaretskii <eliz@gnu.org>
14833 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
14834 for attrs[LFACE_FONTSET_INDEX].
14836 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
14838 * xml.c (parse_region): Remove unused local
14839 that was recently introduced.
14841 2011-07-23 Eli Zaretskii <eliz@gnu.org>
14843 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
14844 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
14846 * xdisp.c (move_it_in_display_line_to): Record the best matching
14847 position for TO_CHARPOS while scanning the line, and restore it on
14848 exit if none of the characters scanned was an exact match.
14849 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
14850 when exact match is impossible due to invisible text, and the
14851 lines are truncated.
14853 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
14855 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
14858 2011-07-22 Eli Zaretskii <eliz@gnu.org>
14860 Fix a significant slow-down of cursor motion with C-n, C-p,
14861 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
14862 auto-repeat under bidi redisplay in fontified buffers.
14863 * xdisp.c (compute_stop_pos_backwards): New function.
14864 (next_element_from_buffer): Call compute_stop_pos_backwards to
14865 find a suitable prev_stop when we find ourselves before
14867 (reseat): Don't look for prev_stop, as that could mean a very long
14869 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
14870 <cached_disp_overlay_modiff>: Cache for last found display string
14872 (compute_display_string_pos): Return the cached position if asked
14873 about the same buffer in the same area of character positions, and
14874 the buffer wasn't changed since the time the display string
14875 position was cached.
14877 2011-07-22 Eli Zaretskii <eliz@gnu.org>
14879 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
14880 is an integer, which is important for empty lines. (Bug#9149)
14882 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
14884 * frame.c (Fmodify_frame_parameters): In tty case, update the
14885 default face if necessary (Bug#4238).
14887 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
14889 * editfns.c (Fstring_to_char): No need to explain what a character
14890 is in the docstring (Bug#6576).
14892 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
14894 * xml.c (parse_region): Make sure we always return a tree.
14896 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
14898 * xml.c (parse_region): If a document contains only comments,
14901 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
14903 * xml.c (make_dom): Return comments, too.
14905 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
14908 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
14909 and the surrounding thread.
14910 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
14911 rather than fgets, and retry after EINTR. Otherwise, 'emacs
14912 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
14914 * s/openbsd.h (BROKEN_SIGIO): Define.
14915 * unexelf.c (unexec) [__OpenBSD__]:
14916 Don't update the .mdebug section of the Alpha COFF symbol table.
14918 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
14920 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
14923 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
14925 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
14926 This fixes some race conditions on the permissions of any newly
14929 * alloc.c (valid_pointer_p): Use pipe, not open.
14930 This fixes some permissions issues when debugging.
14932 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
14933 If fchown fails to set both uid and gid, try to set just gid,
14934 as that is sometimes allowed. Adjust the file's mode to eliminate
14935 setuid or setgid bits that are inappropriate if fchown fails.
14937 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
14939 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
14940 to compare Lisp_Objects.
14941 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
14942 global_gnutls_log_level, don't mistake it for a Lisp_Object.
14943 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
14945 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
14947 * lread.c (read_integer): Unread even EOF character.
14948 (read1): Likewise. Properly record start position of symbol.
14950 * lread.c (read1): Read `#:' as empty uninterned symbol if no
14951 symbol character follows.
14953 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
14955 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
14956 This works around a problem with the previous change to Fcopy_file.
14957 Recent glibc declares fchown with __attribute__((warn_unused_result)),
14958 and without this change, GCC might complain about discarding
14959 fchown's return value.
14961 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
14963 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
14965 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
14967 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
14969 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
14971 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
14972 it's used from the C level.
14974 * process.c: Use the same condition for POLL_FOR_INPUT in both
14975 keyboard.c and process.c (bug#1858).
14977 2011-07-09 Lawrence Mitchell <wence@gmx.li>
14979 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
14980 (Fgnutls_boot): Use it.
14982 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
14984 * doc.c (Fsubstitute_command_keys): Revert last change.
14986 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
14988 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
14989 quotes the next character, and doesn't affect other longer
14990 sequences (bug#8935).
14992 * lread.c (syms_of_lread): Clarify that is isn't only
14993 `eval-buffer' and `eval-defun' that's affected by
14994 `lexical-binding' (bug#8460).
14996 2011-07-15 Eli Zaretskii <eliz@gnu.org>
14998 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
14999 bidi redisplay when a line includes both an image and is truncated.
15001 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
15003 Fix minor problems found by static checking.
15004 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
15005 (elsz): Now a signed constant, not a size_t var. We prefer signed
15006 types to unsigned, to avoid integer comparison confusion. Without
15007 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
15008 "cannot optimize loop, the loop counter may overflow", a symptom
15010 * indent.c (Fvertical_motion): Mark locals as initialized.
15011 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
15013 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
15015 * search.c (Fre_search_backward): Mention `case-fold-search' in
15016 all the re_search_* functions (bug#8138).
15018 * keyboard.c (Fopen_dribble_file): Document when the file is

15028 (compute_display_string_end): Accept additional argument STRING.
15029 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
15030 (reseat_to_string): Initialize bidi_it->string.s and
15031 bidi_it->string.schars.
15032 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
15033 NULL (avoids a crash in bidi_paragraph_init).
15034 Initialize itb.string.lstring.
15035 (init_iterator): Call bidi_init_it only of a valid
15036 buffer position was specified. Initialize paragraph_embedding to
15038 (reseat_to_string): Initialize the bidi iterator.
15039 (display_string): If we need to ignore text properties of
15040 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
15041 original value of -1 will not work with bidi.)
15042 (compute_display_string_pos): First arg is now struct
15043 `text_pos *'; all callers changed. Support display properties on
15045 (compute_display_string_end): Support display properties on Lisp
15047 (init_iterator, reseat_1, reseat_to_string): Initialize the
15048 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
15049 when iterating on a string not from display properties).
15050 (compute_display_string_pos, compute_display_string_end):
15051 Fix calculation of the object to scan. Fixes an error when using
15053 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
15054 base_level_stop; instead, set base_level_stop to BEGV.
15055 Fixes crashes in vertical-motion.
15056 (next_element_from_buffer): Improve commentary for when
15057 the iterator is before prev_stop.
15058 (init_iterator): Initialize bidi_p from the default value of
15059 bidi-display-reordering, not from buffer-local value. Use the
15060 buffer-local value only if initializing for buffer iteration.
15061 (handle_invisible_prop): Support invisible properties on strings
15062 that are being bidi-reordered.
15063 (set_iterator_to_next): Support bidi reordering of C strings and
15065 (next_element_from_string): Support bidi reordering of Lisp
15067 (handle_stop_backwards): Support Lisp strings as well.
15068 (display_string): Support display of R2L glyph rows.
15069 Use IT_STRING_CHARPOS when displaying from a Lisp string.
15070 (init_iterator): Don't initialize it->bidi_p for strings
15072 (reseat_to_string): Initialize it->bidi_p for strings here.
15073 (next_element_from_string, next_element_from_c_string)
15074 (next_element_from_buffer): Add xassert's for correspondence
15075 between IT's object being iterated and it->bidi_it.string
15077 (face_before_or_after_it_pos): Support bidi iteration.
15078 (next_element_from_c_string): Handle the case of the first string
15079 character that is not the first one in the visual order.
15080 (get_visually_first_element): New function, refactored from common
15081 parts of next_element_from_buffer, next_element_from_string, and
15082 next_element_from_c_string.
15083 (tool_bar_lines_needed, redisplay_tool_bar)
15084 (display_menu_bar): Force left-to-right direction. Add a FIXME
15085 comment for making that be controlled by a user option.
15086 (push_it, pop_it): Save and restore the state of the
15087 bidi iterator. Save and restore the bidi_p flag.
15088 (pop_it): Iterate out of display property for string iteration as
15090 (iterate_out_of_display_property): Support iteration over strings.
15091 (handle_single_display_spec): Set up it->bidi_it for iteration
15092 over a display string, and call bidi_init_it.
15093 (handle_single_display_spec, next_overlay_string)
15094 (get_overlay_strings_1, push_display_prop): Set up the bidi
15095 iterator for displaying display or overlay strings.
15096 (forward_to_next_line_start): Don't use the shortcut if
15098 (back_to_previous_visible_line_start): If handle_display_prop
15099 pushed the iterator stack, restore the internal state of the bidi
15100 iterator by calling bidi_pop_it same number of times.
15101 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
15102 and we are bidi-iterating, don't decrement the iterator position;
15103 instead, set the first_elt flag in the bidi iterator, to produce
15105 (reseat_1): Remove redundant setting of string_from_display_prop_p.
15106 (push_display_prop): xassert that we are iterating a buffer.
15107 (push_it, pop_it): Save and restore paragraph_embedding member.
15108 (handle_single_display_spec, next_overlay_string)
15109 (get_overlay_strings_1, reseat_1, reseat_to_string)
15110 (push_display_prop): Set up the `unibyte' member of bidi_it.string
15111 correctly. Don't assume unibyte strings are not bidi-reordered.
15112 (compute_display_string_pos)
15113 (compute_display_string_end): Fix handling the case of C string.
15114 (push_it, pop_it): Save and restore from_disp_prop_p.
15115 (handle_single_display_spec, push_display_prop): Set the
15116 from_disp_prop_p flag.
15117 (get_overlay_strings_1): Reset the from_disp_prop_p flag.
15118 (pop_it): Call iterate_out_of_display_property only if we are
15119 popping after iteration over a string that came from a display
15120 property. Fix a typo in popping stretch info. Add an assertion
15121 for verifying that the iterator position is in sync with the bidi
15123 (handle_single_display_spec, get_overlay_strings_1)
15124 (push_display_prop): Fix initialization of paragraph direction for
15125 string when that of the parent object is not yet determined.
15126 (reseat_1): Call bidi_init_it to resync the bidi
15127 iterator with IT's position. (Bug#7616)
15128 (find_row_edges): If ROW->start.pos gives position
15129 smaller than min_pos, use it as ROW->minpos. (Bug#7616)
15130 (handle_stop, back_to_previous_visible_line_start, reseat_1):
15131 Reset the from_disp_prop_p flag.
15132 (SAVE_IT, RESTORE_IT): New macros.
15133 (pos_visible_p, face_before_or_after_it_pos)
15134 (back_to_previous_visible_line_start)
15135 (move_it_in_display_line_to, move_it_in_display_line)
15136 (move_it_to, move_it_vertically_backward, move_it_by_lines)
15137 (try_scrolling, redisplay_window, display_line): Use them when
15138 saving a temporary copy of the iterator and restoring it back.
15139 (back_to_previous_visible_line_start, reseat_1)
15140 (init_iterator): Empty the bidi cache "stack".
15141 (move_it_in_display_line_to): If iterator ended up at
15142 EOL, but we never saw any buffer positions smaller than
15143 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
15144 motion in bidi-reordered lines.
15145 (move_it_in_display_line_to): Record prev_method and prev_pos
15146 immediately before the call to set_iterator_to_next. Fixes cursor
15147 motion in bidi-reordered lines with stretch glyphs and strings
15148 displayed in margins. (Bug#8133) (Bug#8867)
15149 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
15151 (pos_visible_p): Support positions in bidi-reordered lines.
15152 Save and restore bidi cache.
15154 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.
15155 (bidi_paragraph_info): Delete unused struct.
15156 (bidi_cache_idx, bidi_cache_last_idx): Declare EMACS_INT.
15157 (bidi_cache_start): New variable.
15158 (bidi_cache_reset): Reset bidi_cache_idx to bidi_cache_start, not
15160 (bidi_cache_fetch_state, bidi_cache_search)
15161 (bidi_cache_find_level_change, bidi_cache_iterator_state)
15162 (bidi_cache_find, bidi_peek_at_next_level)

15164 (bidi_move_to_visually_next): Compare cache index with
15165 bidi_cache_start rather than with zero.
15166 (bidi_fetch_char): Accept new argument STRING; all callers
15167 changed. Support iteration over a string. Support strings with
15168 display properties. Support unibyte strings. Fix the type of
15169 `len' according to what STRING_CHAR_AND_LENGTH expects.
15170 (bidi_paragraph_init, bidi_resolve_explicit_1)
15171 (bidi_resolve_explicit, bidi_resolve_weak)
15172 (bidi_level_of_next_char, bidi_move_to_visually_next):
15173 Support iteration over a string.
15174 (bidi_set_sor_type, bidi_resolve_explicit_1)

15267 * buffer.c (Fget_buffer_create): Initialize inhibit_shrinking.
15268 The old code sometimes used this field without initializing it.
15270 * alloc.c (gc_sweep): Don't read past end of array.
15271 In theory, the old code could also have corrupted Emacs internals,
15272 though it'd be very unlikely.

15276 * character.c (Fcharacterp): Don't advertise optional ignored

15535 (clone_per_buffer_values): Don't assume that
15536 sizeof (struct buffer) is a multiple of sizeof (Lisp_Object).
15537 This isn't true in general, and it's particularly not true
15538 if Emacs is configured with --with-wide-int.
15539 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
15540 New macros, used in the buffer.c change.

15576 Random fixes. E.g., (random) never returned negative values.
15577 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
15578 subseconds part to the entropy, as that's a bit more random.
15579 Prefer signed to unsigned, since the signedness doesn't matter and
15580 in general we prefer signed. When given a limit, use a
15581 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
15582 latter isn't right if USE_2_TAGS_FOR_INTS.
15583 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
15584 not 0..VALMASK. Don't discard "excess" bits that random () returns.

15594 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
15596 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
15597 This is more efficient than Ffile_directory_p and avoids a minor race.
15599 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
15601 * buffer.c (Foverlay_put): Say what the return value is
15604 * fileio.c (barf_or_query_if_file_exists): Check first if the file
15605 is a directory before asking whether to use the file name
15607 (barf_or_query_if_file_exists): Make the "File is a directory"
15608 error be more correct.
15610 * fns.c (Frequire): Remove the mention of the .gz files, since
15611 that's installation-specific, but keep the mention of
15612 `get-load-suffixes'.
15614 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
15616 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

15729 * eval.c (struct backtrace): Simplify and port the data structure.
15730 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
15731 signed bit field, as this assumption is not portable and it makes
15732 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
15733 "char debug_on_exit : 1" as this is not portable either; instead,
15734 use the portable "unsigned int debug_on_exit : 1". Remove unused
15735 member evalargs. Remove obsolete comments about cc bombing out.

15925 (read1): Check for integer overflow in radices, and in
15926 read-circle numbers.

15970 on undefined behavior with wrong number of arguments.
15971 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
15972 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
15973 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
15974 since we're not interested in debugging glyphs with old libraries.
15975 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
15976 GCC 4.6.0's static checking.

16018 (x_session_initialize): Do not assume string length fits in int.
16020 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
16021 This is unlikely, but can occur if DPI is outlandish.
16023 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):

16059 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
16061 * filelock.c: Fix some buffer overrun and integer overflow issues.
16062 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
16063 Reformulate so as not to need the command string.
16064 Invoke gzip -cd rather than gunzip, as it's more portable.
16065 (lock_info_type, lock_file_1, lock_file):
16066 Don't assume pid_t and time_t fit in unsigned long.
16067 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
16068 (current_lock_owner): Prefer signed type for sizes.
16069 Use memcpy, not strncpy, where memcpy is what is really wanted.
16070 Don't assume (via atoi) that time_t and pid_t fit in int.
16071 Check for time_t and/or pid_t out of range, e.g., via a network share.
16072 Don't alloca where an auto var works fine.
16074 * fileio.c: Fix some integer overflow issues.
16075 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
16076 Don't assume string length fits in int.
16077 (directory_file_name): Don't assume string length fits in long.
16078 (make_temp_name): Don't assume pid fits in int, or that its print
16079 length is less than 20.
16081 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
16083 * coding.c (make_subsidiaries): Don't assume string length fits in int.
16085 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
16087 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
16088 We prefer signed integers, even for size calculations.
16090 * emacs.c: Don't assume string length fits in 'int'.
16091 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
16092 (main): Don't invoke strlen when not needed.
16094 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
16095 (XD_DEBUG_MESSAGE): Don't waste a byte.
16097 * callproc.c (getenv_internal_1, getenv_internal)
16098 (Fgetenv_internal):
16099 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
16101 * lread.c (invalid_syntax): Omit length argument.
16102 All uses changed. This doesn't fix a bug, but it simplifies the
16103 code away from its former Hollerith-constant appearance, and it's
16104 one less 'int' to worry about when looking at integer-overflow issues.
16105 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
16107 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
16108 This didn't break anything, but it didn't help either.
16109 It's confusing to put a bogus integer in a place where the actual
16110 value does not matter.
16111 (LIST_END_P): Remove unused macro and its bogus comment.
16112 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
16114 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
16115 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
16117 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
16118 We prefer signed types, and the value cannot exceed the EMACS_INT
16119 range anyway (because otherwise the length would not be representable).
16120 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
16121 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
16122 This avoids a GCC warning when WIDE_EMACS_INT.
16124 * indent.c (sane_tab_width): New function.
16125 (current_column, scan_for_column, Findent_to, position_indentation)
16126 (compute_motion): Use it. This is just for clarity.
16127 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
16129 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
16131 * lisp.h (lint_assume): New macro.
16132 * composite.c (composition_gstring_put_cache):
16133 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
16135 * editfns.c, insdel.c:
16136 Omit unnecessary forward decls, to simplify future changes.
16138 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
16140 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
16142 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
16143 Use much-faster test for byte-length change.
16144 Don't assume string byte-length fits in 'int'.
16145 Check that character arg fits in 'int'.
16146 (mapcar1): Declare byte as byte, for clarity.
16148 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
16150 * fns.c (concat): Catch string overflow earlier.
16151 Do not rely on integer wraparound.
16153 * dispextern.h (struct it.overlay_strings_charpos)
16154 (struct it.selective): Now EMACS_INT, not int.
16155 * xdisp.c (forward_to_next_line_start)
16156 (back_to_previous_visible_line_start)
16157 (reseat_at_next_visible_line_start, next_element_from_buffer):
16158 Don't arbitrarily truncate the value of 'selective' to int.
16160 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
16162 * composite.c: Don't truncate sizes to 'int'.
16163 (composition_gstring_p, composition_reseat_it)
16164 (composition_adjust_point): Use EMACS_INT, not int.
16165 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
16166 not EMACS_UINT, for indexes.
16168 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
16170 * buffer.c: Include <verify.h>.
16171 (struct sortvec.priority, struct sortstr.priority):
16172 Now EMACS_INT, not int.
16173 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
16174 (struct sortstr.size, record_overlay_string)
16175 (struct sortstrlist.size, struct sortlist.used):
16176 Don't truncate size to int.
16177 (record_overlay_string): Check for size-calculation overflow.
16178 (init_buffer_once): Check at compile-time, not run-time.
16180 2011-06-22 Jim Meyering <meyering@redhat.com>
16182 Don't leak an XBM-image-sized buffer
16183 * image.c (xbm_load): Free the image buffer after using it.
16185 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
16188 * composite.c (find_automatic_composition): Omit needless 'return 0;'
16189 that Sun C diagnosed.
16190 * fns.c (secure_hash): Fix pointer signedness issue.
16191 * intervals.c (static_offset_intervals): New function.
16192 (offset_intervals): Use it.
16194 2011-06-21 Leo Liu <sdl.web@gmail.com>
16197 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
16200 * fns.c (secure_hash): Rename from crypto_hash_function and change
16201 the first arg to accept symbols.
16202 (Fsecure_hash): New primitive.
16203 (syms_of_fns): New symbols.
16205 2011-06-20 Deniz Dogan <deniz@dogan.se>
16207 * process.c (Fset_process_buffer): Clarify return value in
16210 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
16212 * dispnew.c (add_window_display_history): Use BVAR.
16214 * xdisp.c (debug_method_add): Use BVAR.
16215 (check_window_end, dump_glyph_matrix, dump_glyph)
16216 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
16218 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
16221 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
16222 check till after the cache is created in init_frame_faces.
16224 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
16226 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
16228 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
16230 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
16231 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
16232 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
16234 Improve buffer-overflow checking (Bug#8873).
16235 * fileio.c (Finsert_file_contents):
16236 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
16237 Remove the old (too-loose) buffer overflow checks.
16238 They weren't needed, since make_gap checks for buffer overflow.
16239 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
16240 The old code merely checked for Emacs fixnum overflow, and relied
16241 on undefined (wraparound) behavior. The new code avoids undefined
16242 behavior, and also checks for ptrdiff_t and/or size_t overflow.
16244 * editfns.c (Finsert_char): Don't dump core with very negative counts.
16245 Tune. Don't use wider integers than needed. Don't use alloca.
16246 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
16248 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
16250 * insdel.c, lisp.h (buffer_overflow): New function.
16251 (insert_from_buffer_1, replace_range, replace_range_2):
16252 * insdel.c (make_gap_larger):
16253 * editfns.c (Finsert_char):
16254 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
16256 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
16258 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
16260 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
16262 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
16263 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
16265 * fileio.c: Don't assume EMACS_INT fits in off_t.
16266 (emacs_lseek): New static function.
16267 (Finsert_file_contents, Fwrite_region): Use it.
16268 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
16270 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
16272 * fns.c: Don't overflow int when computing a list length.
16273 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
16274 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
16275 truncation on 64-bit hosts. Check for QUIT every
16276 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
16277 faster and is responsive enough.
16278 (Flength): Report an error instead of overflowing an integer.
16279 (Fsafe_length): Return a float if the value is not representable
16280 as a fixnum. This shouldn't happen except in contrived situations.
16281 (Fnthcdr, Fsort): Don't assume list length fits in int.
16282 (Fcopy_sequence): Don't assume vector length fits in int.
16284 * alloc.c: Check that resized vectors' lengths fit in fixnums.
16285 (header_size, word_size): New constants.
16286 (allocate_vectorlike): Don't check size overflow here.
16287 (allocate_vector): Check it here instead, since this is the only
16288 caller of allocate_vectorlike that could cause overflow.
16289 Check that the new vector's length is representable as a fixnum.
16291 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
16292 The previous code was bogus. For example, next_almost_prime (32)
16293 returned 39, which is undesirable as it is a multiple of 3; and
16294 next_almost_prime (24) returned 25, which is a multiple of 5 so
16295 why was the code bothering to check for multiples of 7?
16297 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
16299 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
16301 Variadic C functions now count arguments with ptrdiff_t.
16302 This partly undoes my 2011-03-30 change, which replaced int with size_t.
16303 Back then I didn't know that the Emacs coding style prefers signed int.
16304 Also, in the meantime I found a few more instances where arguments
16305 were being counted with int, which may truncate counts on 64-bit
16306 machines, or EMACS_INT, which may be unnecessarily wide.
16307 * lisp.h (struct Lisp_Subr.function.aMANY)
16308 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
16309 Arg counts are now ptrdiff_t, not size_t.
16310 All variadic functions and their callers changed accordingly.
16311 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
16312 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
16313 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
16314 * callint.c (Fcall_interactively): Check arg count for overflow,
16315 to avoid potential buffer overrun. Use signed char, not 'int',
16316 for 'varies' array, so that we needn't bother to check its size
16317 calculation for overflow.
16318 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
16319 * eval.c (apply_lambda):
16320 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
16321 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
16322 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
16324 * callint.c (Fcall_interactively): Don't use index var as event count.
16326 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
16327 * mem-limits.h (SIZE): Remove; no longer used.
16329 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
16331 Remove unnecessary casts.
16332 * xterm.c (x_term_init):
16333 * xfns.c (x_set_border_pixel):
16334 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
16335 These aren't needed now that we assume ANSI C.
16337 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
16338 It's more likely to cause problems (due to unsigned overflow)
16341 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
16343 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
16345 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
16347 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
16349 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
16351 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
16353 GLYPH_CODE_FACE returns EMACS_INT, not int.
16354 * dispextern.h (merge_faces):
16355 * xfaces.c (merge_faces):
16356 * xdisp.c (get_next_display_element, next_element_from_display_vector):
16357 Don't assume EMACS_INT fits in int.
16359 * character.h (CHAR_VALID_P): Remove unused parameter.
16360 * fontset.c, lisp.h, xdisp.c: All uses changed.
16362 * editfns.c (Ftranslate_region_internal): Omit redundant test.
16364 * fns.c (concat): Minor tuning based on overflow analysis.
16365 This doesn't fix any bugs. Use int to hold character, instead
16366 of constantly refetching from Emacs object. Use XFASTINT, not
16367 XINT, for value known to be a character. Don't bother comparing
16368 a single byte to 0400, as it's always less.
16370 * floatfns.c (Fexpt):
16371 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
16373 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
16376 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
16378 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
16379 Without this fix, on a 64-bit host (aset S 0 4294967386) would
16380 incorrectly succeed when S was a string, because 4294967386 was
16381 truncated before it was used.
16383 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
16384 Otherwise, an out-of-range integer could cause undefined behavior
16387 * composite.c: Use int, not EMACS_INT, for characters.
16388 (fill_gstring_body, composition_compute_stop_pos): Use int, not
16389 EMACS_INT, for values that are known to be in character range.
16390 This doesn't fix any bugs but is the usual style inside Emacs and
16391 may generate better code on 32-bit machines.
16393 Make sure a 64-bit char is never passed to ENCODE_CHAR.
16394 This is for reasons similar to the recent CHAR_STRING fix.
16395 * charset.c (Fencode_char): Check that character arg is actually
16396 a character. Pass an int to ENCODE_CHAR.
16397 * charset.h (ENCODE_CHAR): Verify that the character argument is no
16398 wider than 'int', as a compile-time check to prevent future regressions
16401 * character.c (char_string): Remove unnecessary casts.
16403 Make sure a 64-bit char is never passed to CHAR_STRING.
16404 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
16405 by silently ignoring the top 32 bits, allowing some values
16406 that were far too large to be valid characters.
16407 * character.h: Include <verify.h>.
16408 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
16409 arguments are no wider than unsigned, as a compile-time check
16410 to prevent future regressions in this area.
16412 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
16413 (Fsubst_char_in_region):
16415 * xdisp.c (decode_mode_spec_coding):
16416 Adjust to CHAR_STRING's new requirement.
16417 * editfns.c (Finsert_char, Fsubst_char_in_region):
16418 * fns.c (concat): Check that character args are actually
16419 characters. Without this test, these functions did the wrong
16420 thing with wildly out-of-range values on 64-bit hosts.
16422 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
16423 These casts should not be needed on 32-bit hosts, either.
16424 * keyboard.c (read_char):
16425 * lread.c (Fload): Remove casts to unsigned.
16427 * lisp.h (UNSIGNED_CMP): New macro.
16428 This fixes comparison bugs on 64-bit hosts.
16429 (ASCII_CHAR_P): Use it.
16430 * casefiddle.c (casify_object):
16431 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
16432 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
16433 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
16434 * dispextern.h (FACE_FROM_ID):
16435 * keyboard.c (read_char): Use UNSIGNED_CMP.
16437 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
16438 not to EMACS_INT, to avoid GCC warning.
16440 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
16442 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
16443 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
16444 isn't needed on 32-bit machines.
16446 * buffer.c (Fgenerate_new_buffer_name):
16447 Use EMACS_INT for count, not int.
16448 (advance_to_char_boundary): Return EMACS_INT, not int.
16450 * data.c (Qcompiled_function): Now static.
16452 * window.c (window_body_lines): Now static.
16454 * image.c (gif_load): Rename local to avoid shadowing.
16456 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
16457 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
16458 * alloc.c (make_save_value): Integer argument is now of type
16459 ptrdiff_t, not int.
16460 (mark_object): Use ptrdiff_t, not int.
16461 * lisp.h (pD): New macro.
16462 * print.c (print_object): Use it.
16464 * alloc.c: Use EMACS_INT, not int, to count objects.
16465 (total_conses, total_markers, total_symbols, total_vector_size)
16466 (total_free_conses, total_free_markers, total_free_symbols)
16467 (total_free_floats, total_floats, total_free_intervals)
16468 (total_intervals, total_strings, total_free_strings):
16469 Now EMACS_INT, not int. All uses changed.
16470 (Fgarbage_collect): Compute overall total using a double, so that
16471 integer overflow is less likely to be a problem. Check for overflow
16472 when converting back to an integer.
16473 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
16474 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
16475 These were 'int' variables that could overflow on 64-bit hosts;
16476 they were never used, so remove them instead of repairing them.
16477 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
16478 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
16479 Previously, this ceilinged at INT_MAX, but that doesn't work on
16481 (allocate_pseudovector): Don't use EMACS_INT when int would do.
16483 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
16484 (allocate_vectorlike): Check for ptrdiff_t overflow.
16485 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
16486 when a (possibly-narrower) signed value would do just as well.
16487 We prefer using signed arithmetic, to avoid comparison confusion.
16489 * alloc.c: Catch some string size overflows that we were missing.
16490 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
16491 for convenience in STRING_BYTES_MAX.
16492 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
16493 The definition here is exact; the one in lisp.h was approximate.
16494 (allocate_string_data): Check for string overflow. This catches
16495 some instances we weren't catching before. Also, it catches
16496 size_t overflow on (unusual) hosts where SIZE_MAX <= min

16940 * buffer.h (struct buffer.modtime): Now time_t, not int.
16941 * fileio.c (Fvisited_file_modtime): No need for time_t cast now.
16942 * undo.c (Fprimitive_undo): Use time_t, not int, for time_t value.
16944 Minor fixes for signed vs unsigned integers.
16945 * character.h (MAYBE_UNIFY_CHAR):
16946 * charset.c (maybe_unify_char):
16947 * keyboard.c (read_char, reorder_modifiers):
16948 XINT -> XFASTINT, since the integer must be nonnegative.
16949 * ftfont.c (ftfont_spec_pattern):
16950 * keymap.c (access_keymap, silly_event_symbol_error):
16951 XUINT -> XFASTINT, since the integer must be nonnegative.
16952 (Fsingle_key_description, preferred_sequence_p): XUINT -> XINT,
16953 since it makes no difference and we prefer signed.
16954 * keyboard.c (record_char): Use XUINT when all the neighbors do.
16955 (access_keymap): NATNUMP -> INTEGERP, since the integer must be

17001 (Fselected_window, select_window, Fselect_window): Move up in
17002 code. Minor doc-string fixes.
17004 2011-06-06 Paul Eggert <eggert@cs.ucla.edu>
17006 * alloc.c (memory_full) [SYSTEM_MALLOC]: Port to MacOS (Bug#8800).
17007 Do not assume that spare memory exists; that assumption is valid
17008 only if SYSTEM_MALLOC.
17009 (LARGE_REQUEST): New macro, so that the issue of large requests
17010 is separated from the issue of spare memory.
17012 2011-06-05 Andreas Schwab <schwab@linux-m68k.org>
17014 * editfns.c (Fformat): Correctly handle zero flag with hexadecimal

17040 New error handlers.
17041 (x_clipboard_manager_save_frame, x_clipboard_manager_save_all):
17042 Obey Vx_select_enable_clipboard_manager. Catch errors in
17043 x_clipboard_manager_save (Bug#8779).
17044 (Vx_select_enable_clipboard_manager): New variable.
17045 (x_get_foreign_selection): Reduce scope of x_catch_errors (Bug#8790).
17047 2011-06-04 Dan Nicolaescu <dann@ics.uci.edu>
17049 * emacs.c (main): Warn when starting a GTK emacs in daemon mode.
17051 2011-06-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17053 * fringe.c (update_window_fringes): Don't update overlay arrow bitmap
17054 in the current matrix if keep_current_p is non-zero.

17062 Support bidi reordering of text covered by display properties.
17064 * bidi.c (bidi_copy_it): Use offsetof instead of emulating it.
17065 (bidi_fetch_char, bidi_fetch_char_advance): New functions.
17066 (bidi_cache_search, bidi_cache_iterator_state)
17067 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
17068 (bidi_level_of_next_char, bidi_move_to_visually_next):
17069 Support character positions inside a run of characters covered by a
17071 (bidi_paragraph_init, bidi_resolve_explicit_1)
17072 (bidi_level_of_next_char): Call bidi_fetch_char and
17073 bidi_fetch_char_advance instead of FETCH_CHAR and

17076 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
17078 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
17079 instead of using explicit *_CHAR codes.
17080 (bidi_resolve_explicit, bidi_resolve_weak):
17081 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
17082 bidirectional text is supported only in multibyte buffers.
17083 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
17084 it to initialize the frame_window_p member of struct bidi_it.
17085 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
17086 (bidi_resolve_explicit, bidi_resolve_weak)

17088 bidi_it->nchars is non-positive.
17089 (bidi_level_of_next_char): Don't try to lookup the cache for the
17090 next/previous character if nothing is cached there yet, or if we
17091 were just reseat()'ed to a new position.
17093 * xdisp.c (set_cursor_from_row): Set start and stop points
17094 according to the row's direction when priming the loop that looks
17095 for the glyph on which to display cursor.
17096 (single_display_spec_intangible_p): Function deleted.
17097 (display_prop_intangible_p): Reimplement to call
17098 handle_display_spec instead of single_display_spec_intangible_p.
17099 Accept 3 additional arguments needed by handle_display_spec.
17100 This fixes incorrect cursor motion across display property with complex
17101 values: lists, `(when COND...)' forms, etc.
17102 (single_display_spec_string_p): Support property values that are
17103 lists with the argument STRING its top-level element.
17104 (display_prop_string_p): Fix the condition for processing a
17105 property that is a list to be consistent with handle_display_spec.
17106 (handle_display_spec): New function, refactored from the
17107 last portion of handle_display_prop.
17108 (compute_display_string_pos): Accept additional argument
17109 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
17110 value of a `display' property is a "replacing spec".
17111 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
17112 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
17113 the display property, but just return a value indicating whether
17114 the display property will replace the characters it covers.
17115 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
17116 frame_window_p members of struct bidi_it.
17117 (compute_display_string_pos, compute_display_string_end):
17119 (push_it): Accept second argument POSITION, where pop_it should
17120 jump to continue iteration.
17121 (reseat_1): Initialize bidi_it.disp_pos.
17123 * keyboard.c (adjust_point_for_property): Adjust the call to
17124 display_prop_intangible_p to its new signature.
17126 * dispextern.h (struct bidi_it): New member frame_window_p.
17127 (bidi_init_it): Update prototypes.
17128 (display_prop_intangible_p): Update prototype.
17129 (compute_display_string_pos, compute_display_string_end):

17134 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
17136 Malloc failure behavior now depends on size of allocation.
17137 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
17138 * lisp.h: Change signatures accordingly.
17139 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
17140 All callers changed. (Bug#8762)
17142 * gnutls.c: Use Emacs's memory allocators.
17143 Without this change, the gnutls library would invoke malloc etc.
17144 directly, which causes problems on non-SYNC_INPUT hosts, and which
17145 runs afoul of improving memory_full behavior. (Bug#8761)
17146 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
17147 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
17148 xfree instead of the default malloc, realloc, free.
17149 (Fgnutls_boot): No need to check for memory allocation failure,
17150 since xmalloc does that for us.
17152 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
17153 * category.c (hash_get_category_set):
17154 * ccl.c (ccl_driver):

17166 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
17167 (Fsxhash, Fgethash, Fputhash, Fmaphash):
17168 * image.c (make_image, search_image_cache, lookup_image)
17169 (xpm_put_color_table_h):
17170 * lisp.h (struct Lisp_Hash_Table):
17171 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
17172 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
17173 for hashes and hash indexes, instead of 'unsigned' and 'int'.
17174 * alloc.c (allocate_vectorlike):
17175 Check for overflow in vector size calculations.
17176 * ccl.c (ccl_driver):
17177 Check for overflow when converting EMACS_INT to int.
17178 * fns.c, image.c: Remove unnecessary static decls that would otherwise
17179 need to be updated by these changes.
17180 * fns.c (make_hash_table, maybe_resize_hash_table):
17181 Check for integer overflow with large hash tables.
17182 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
17183 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
17184 (SXHASH_REDUCE): New macro.
17185 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
17186 Use it instead of discarding useful hash info with large hash values.
17187 (sxhash_float): New function.
17188 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
17189 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
17190 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
17191 Rewrite to use FIXNUM_BITS, as this simplifies things.
17192 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
17193 Adjust signatures to match updated version of code.
17194 (consing_since_gc): Now EMACS_INT, since a single hash table can
17195 use more than INT_MAX bytes.
17197 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
17199 Make it possible to build with GCC-4.6+ -O2 -flto.
17201 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
17203 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
17205 * minibuf.c (get_minibuffer, read_minibuf_unwind):
17206 Call minibuffer-inactive-mode.
17208 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
17210 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
17211 Update dependencies.
17213 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
17215 * data.c (init_data): Remove code for UTS, this system is not
17218 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
17220 Don't force ./temacs to start in terminal mode.
17222 * frame.c (make_initial_frame): Initialize faces in all cases, not
17223 only when CANNOT_DUMP is defined.
17224 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
17226 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
17228 * dispnew.c (add_window_display_history): Use const for the string
17229 pointer. Remove declaration, not needed.
17231 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
17233 Use 'inline', not 'INLINE'.
17234 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
17235 * alloc.c, fontset.c (INLINE): Remove.
17236 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
17237 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
17238 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
17239 * gmalloc.c (register_heapinfo): Use inline unconditionally.
17240 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
17242 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
17244 Make it possible to run ./temacs.
17246 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
17247 syms_of_callproc does the same thing. Remove test for
17248 "initialized", do it in the caller.
17249 * emacs.c (main): Avoid calling set_initial_environment when dumping.
17251 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
17253 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
17254 (read_minibuf): Use get_minibuffer.
17255 (syms_of_minibuf): Use DEFSYM.
17256 (Qmetadata): New var.
17257 * data.c (Qbuffer): Don't make it static.
17258 (syms_of_data): Use DEFSYM.
17260 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
17262 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
17263 (CCL_CODE_MIN): New macro.
17265 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
17267 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
17269 * eval.c (Qdebug): Now static.
17270 * lisp.h (Qdebug): Remove decl. This reverts a part of the
17271 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
17272 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
17274 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
17276 * image.c: Various fixes to ImageMagick code comments.
17277 (Fimagemagick_types): Doc fix.
17279 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
17281 Minor fixes prompted by GCC 4.6.0 warnings.
17283 * xselect.c (converted_selections, conversion_fail_tag): Now static.
17285 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
17286 (x_clipboard_manager_save_all): Move extern decl to ...
17287 * xterm.h: ... here, so that it can be checked for consistency.
17289 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
17291 * xselect.c (x_clipboard_manager_save_frame)
17292 (x_clipboard_manager_save_all): New functions.
17293 (Fx_clipboard_manager_save): Lisp function deleted.
17295 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
17296 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
17298 * xterm.h: Update prototype.
17300 2011-05-28 William Xu <william.xwl@gmail.com>
17302 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
17303 exiting (Bug#8239).
17305 2011-05-28 Jim Meyering <meyering@redhat.com>
17307 Avoid a sign-extension bug in crypto_hash_function.
17308 * fns.c (to_uchar): Define.
17309 (crypto_hash_function): Use it to convert some newly-signed
17310 variables to unsigned, to avoid sign-extension bugs. For example,
17311 without this change, (md5 "truc") would evaluate to
17312 45723a2aff78ff4fff7fff1114760e62 rather than the expected
17313 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
17314 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
17316 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
17318 Integer overflow fixes.
17320 * dbusbind.c: Serial number integer overflow fixes.
17321 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
17322 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
17323 to hold a serial number that is too large for a fixnum.
17324 (Fdbus_method_return_internal, Fdbus_method_error_internal):
17325 Check for serial numbers out of range. Decode any serial number
17326 that was so large that it became a float. (Bug#8722)
17328 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
17329 (Fdbus_call_method, Fdbus_call_method_asynchronously):
17330 Use XFASTINT rather than XUINT when numbers are nonnegative.
17331 (xd_append_arg, Fdbus_method_return_internal):
17332 (Fdbus_method_error_internal): Likewise. Also, for unsigned
17333 arguments, check that Lisp number is nonnegative, rather than
17334 silently wrapping negative numbers around. (Bug#8722)
17335 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
17338 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
17340 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
17342 ccl: Add integer overflow checks.
17343 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
17344 (IN_INT_RANGE): New macros.
17345 (ccl_driver): Use them to check for integer overflow when
17346 decoding a CCL program. Many of the new checks are whether XINT (x)
17347 fits in int; it doesn't always, on 64-bit hosts. The new version
17348 doesn't catch all possible integer overflows, but it's an
17349 improvement. (Bug#8719)
17351 * alloc.c (make_event_array): Use XINT, not XUINT.
17352 There's no need for unsigned here.
17354 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
17355 This follows up to the 2011-05-06 change that substituted uintptr_t
17356 for EMACS_INT. This case wasn't caught back then.
17358 Rework Fformat to avoid integer overflow issues.
17359 * editfns.c: Include <float.h> unconditionally, as it's everywhere
17360 now (part of C89). Include <verify.h>.
17361 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
17362 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
17363 (Fformat): Avoid the prepass trying to compute sizes; it was only
17364 approximate and thus did not catch overflow reliably. Instead, walk
17365 through the format just once, formatting and computing sizes as we go,
17366 checking for integer overflow at every step, and allocating a larger
17367 buffer as needed. Keep track separately whether the format is
17368 multibyte. Keep only the most-recently calculated precision, rather
17369 than them all. Record whether each argument has been converted to
17370 string. Use EMACS_INT, not int, for byte and char and arg counts.
17371 Support field widths and precisions larger than INT_MAX. Avoid
17372 sprintf's undefined behavior with conversion specifications such as %#d
17373 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
17374 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
17375 formatting out-of-range floating point numbers with int
17376 formats. (Bug#8668)
17378 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
17380 * data.c: Avoid integer truncation in expressions involving floats.
17381 * data.c: Include <intprops.h>.
17382 (arith_driver): When there's an integer overflow in an expression
17383 involving floating point, convert the integers to floating point
17384 so that the resulting value does not suffer from catastrophic
17385 integer truncation. For example, on a 64-bit host (* 4
17386 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
17387 Do not rely on undefined behavior after integer overflow.
17389 merge count_size_as_multibyte, parse_str_to_multibyte
17390 * character.c, character.h (count_size_as_multibyte):
17391 Rename from parse_str_to_multibyte; all uses changed.
17392 Check for integer overflow.
17393 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
17394 since it's now a duplicate of the other. This is more of
17395 a character than a buffer op, so better that it's in character.c.
17396 * fns.c, print.c: Adjust to above changes.
17398 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
17400 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
17402 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
17404 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
17405 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
17406 (x_clipboard_manager_save): Now static.
17407 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
17409 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
17410 (crypto_hash_function): Now static.
17411 Fix pointer signedness problems. Avoid unnecessary initializations.
17413 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
17415 * termhooks.h (Vselection_alist): Make it terminal-local.
17417 * terminal.c (create_terminal): Initialize it.
17419 * xselect.c: Support for clipboard managers.
17420 (Vselection_alist): Move to termhooks.h as terminal-local var.
17421 (LOCAL_SELECTION): New macro.
17422 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
17423 (symbol_to_x_atom): Remove gratuitous arg.
17424 (x_handle_selection_request, lisp_data_to_selection_data)
17425 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
17426 (x_own_selection, x_get_local_selection, x_convert_selection):
17427 New arg, specifying work frame. Use terminal-local Vselection_alist.
17428 (some_frame_on_display): Delete unused function.
17429 (Fx_own_selection_internal, Fx_get_selection_internal)
17430 (Fx_disown_selection_internal, Fx_selection_owner_p)
17431 (Fx_selection_exists_p): New optional frame arg.
17432 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
17433 (x_handle_selection_clear): Don't treat other terminals with the
17434 same keyboard specially. Use the terminal-local Vselection_alist.
17435 (x_clear_frame_selections): Use Frun_hook_with_args.
17437 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
17439 * xterm.h: Add support for those atoms.
17441 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
17443 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
17444 (converted_selections, conversion_fail_tag): New global variables.
17445 (x_selection_request_lisp_error): Free the above.
17446 (x_get_local_selection): Remove unnecessary code.
17447 (x_reply_selection_request): Args changed; handle arbitrary array
17448 of converted selections stored in converted_selections.
17449 Separate the XChangeProperty and SelectionNotify steps.
17450 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
17451 (x_convert_selection): New function.
17452 (x_handle_selection_event): Simplify.
17453 (x_get_foreign_selection): Don't ignore incoming requests while
17454 waiting for an answer; this will fail when we implement
17455 SAVE_TARGETS, and seems unnecessary anyway.
17456 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
17457 (Vx_sent_selection_functions): Doc fix.
17459 2011-05-26 Leo Liu <sdl.web@gmail.com>
17461 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
17463 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17465 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
17467 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
17468 for fringe update if it has periodic bitmap.
17469 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
17470 and fringe_bitmap_periodic_p.
17472 * fringe.c (get_fringe_bitmap_data): New function.
17473 (draw_fringe_bitmap_1, update_window_fringes): Use it.
17474 (update_window_fringes): Record periodicity of fringe bitmap in glyph
17475 row. Mark glyph row for fringe update if periodicity changed.
17477 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
17478 for fringe update unless it has periodic bitmap.
17480 2011-05-25 Kenichi Handa <handa@m17n.org>
17482 * xdisp.c (get_next_display_element): Set correct it->face_id for
17483 a static composition.
17485 2011-05-24 Leo Liu <sdl.web@gmail.com>
17488 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
17490 * fns.c (crypto_hash_function, Fsha1): New function.
17491 (Fmd5): Use crypto_hash_function.
17492 (syms_of_fns): Add Ssha1.
17494 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
17496 * gnutls.c: Remove unused macros.
17497 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
17498 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
17499 Remove macros that are defined and never used.
17500 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
17502 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
17504 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
17505 (Fx_get_selection_internal): Minor cleanup.
17506 (Fx_own_selection_internal): Rename arguments for consistency with
17509 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
17511 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
17513 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
17515 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
17517 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17519 * dispnew.c (scrolling_window): Don't exclude the case that the
17520 last enabled row in the desired matrix touches the bottom boundary.
17522 2011-05-21 Glenn Morris <rgm@gnu.org>
17524 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
17525 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
17526 and add some more files.
17528 2011-05-20 Eli Zaretskii <eliz@gnu.org>
17530 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
17531 report_file_error introduced by the change from 2011-05-07.
17533 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
17535 * systime.h (Time): Define only if emacs is defined.
17536 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
17537 where the include path doesn't have X11/X.h by default. See
17538 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
17540 2011-05-20 Kenichi Handa <handa@m17n.org>
17542 * composite.c (find_automatic_composition): Fix previous change.
17544 2011-05-20 Glenn Morris <rgm@gnu.org>
17546 * lisp.mk: New file, split from Makefile.in.
17547 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
17548 (shortlisp): Remove.
17549 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
17551 2011-05-19 Glenn Morris <rgm@gnu.org>
17553 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
17554 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
17555 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
17556 (lisp): Set the order to that of loadup.el.
17557 (shortlisp): Make it a copy of $lisp.
17558 (SOME_MACHINE_LISP): Remove.
17559 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
17560 Use just $shortlisp, not $SOME_MACHINE_LISP too.
17562 2011-05-18 Kenichi Handa <handa@m17n.org>
17564 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
17565 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
17566 (find_automatic_composition): Mostly rewrite for efficiency.
17568 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
17570 * makefile.w32-in: Update dependencies.
17572 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
17574 * menu.c: Include limits.h (fixes the MS-Windows build broken by
17575 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
17577 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
17579 Fix some integer overflow issues, such as string length overflow.
17581 * insdel.c (count_size_as_multibyte): Check for string overflow.
17583 * character.c (lisp_string_width): Check for string overflow.
17584 Use EMACS_INT, not int, for string indexes and lengths; in
17585 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
17586 the resulting string length overflows an EMACS_INT; instead,
17587 report a string overflow if no precision given. When checking for
17588 precision exhaustion, use a check that cannot possibly have
17589 integer overflow. (Bug#8675)
17590 * character.h (lisp_string_width): Adjust to new signature.
17592 * alloc.c (string_overflow): New function.
17593 (Fmake_string): Use it. This doesn't change behavior, but saves
17594 a few bytes and will simplify future changes.
17595 * character.c (string_escape_byte8): Likewise.
17596 * lisp.h (string_overflow): New decl.
17598 Fixups, following up to the user-interface timestamp change.
17599 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
17600 for UI timestamps, instead of unsigned long.
17601 * msdos.c (mouse_get_pos): Likewise.
17602 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
17603 * w32gui.h (Time): Define by including "systime.h" rather than by
17604 declaring it ourselves. (Bug#8664)
17606 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
17607 * image.c (clear_image_cache): Likewise.
17609 * term.c (term_mouse_position): Don't assume time_t wraparound.
17611 Be more systematic about user-interface timestamps.
17612 Before, the code sometimes used 'Time', sometimes 'unsigned long',
17613 and sometimes 'EMACS_UINT', to represent these timestamps.
17614 This change causes it to use 'Time' uniformly, as that's what X uses.
17615 This makes the code easier to follow, and makes it easier to catch
17616 integer overflow bugs such as Bug#8664.
17617 * frame.c (Fmouse_position, Fmouse_pixel_position):
17618 Use Time, not unsigned long, for user-interface timestamps.
17619 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
17620 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
17621 * keyboard.h (last_event_timestamp): Likewise.
17622 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
17623 * menu.h (xmenu_show): Likewise.
17624 * term.c (term_mouse_position): Likewise.
17625 * termhooks.h (struct input_event.timestamp): Likewise.
17626 (struct terminal.mouse_position_hook): Likewise.
17627 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
17628 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
17629 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
17630 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
17631 what it was before.
17632 * menu.h, termhooks.h: Include "systime.h", for Time.
17634 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
17635 Don't assume that the difference between two unsigned long values
17636 can fit into an integer. At this point, we know button_down_time
17637 <= event->timestamp, so the difference must be nonnegative, so
17638 there's no need to cast the result if double-click-time is
17639 nonnegative, as it should be; check that it's nonnegative, just in
17640 case. This bug is triggered when events are more than 2**31 ms
17641 apart (about 25 days). (Bug#8664)
17643 * xselect.c (last_event_timestamp): Remove duplicate decl.
17644 (x_own_selection): Remove needless cast to unsigned long.
17646 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
17647 that always fit in int. Use a sentinel instead of a counter, to
17648 avoid a temp and to allay GCC's concerns about possible int overflow.
17649 * frame.h (struct frame): Use int for menu_bar_items_used
17650 instead of EMACS_INT, since it always fits in int.
17652 * menu.c (grow_menu_items): Check for int overflow.
17654 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
17656 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
17657 Before, the code was not consistent. These values cannot exceed
17658 2**31 - 1 so there's no need to make them unsigned.
17659 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
17660 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
17661 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
17663 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
17665 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
17666 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
17667 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
17668 presumably because the widths might not match.
17670 * window.c (size_window): Avoid needless test at loop start.
17672 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
17674 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
17676 2011-05-12 Drew Adams <drew.adams@oracle.com>
17678 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
17680 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17682 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
17683 `width' to `bar_area_x' and `bar_area_width', respectively.
17684 (x_scroll_run): Take account of fringe background extension.
17686 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
17687 Rename local vars `left' and `width' to `bar_area_x' and
17688 `bar_area_width', respectively.
17689 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
17690 background extension.
17692 2011-05-10 Jim Meyering <meyering@redhat.com>
17694 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
17696 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
17698 * image.c (Finit_image_library): Return t for built-in image types,
17699 like pbm and xbm. (Bug#8640)
17701 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
17703 * w32menu.c (set_frame_menubar): Fix submenu allocation.
17705 2011-05-07 Eli Zaretskii <eliz@gnu.org>
17707 * w32console.c (Fset_screen_color): Doc fix.
17708 (Fget_screen_color): New function.
17709 (syms_of_ntterm): Defsubr it.
17711 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
17712 unlink the temporary file if Fcall_process didn't create it in the
17714 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
17715 child process will be redirected to a file specified with `:file'.
17716 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
17717 cue to call_process_cleanup not to close that handle.
17719 2011-05-07 Ben Key <bkey76@gmail.com>
17721 * makefile.w32-in: The bootstrap-temacs rule now makes use of
17722 one of two shell specific rules, either bootstrap-temacs-CMD or
17723 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
17724 to the previous implementation of the bootstrap-temacs rule.
17725 The bootstrap-temacs-CMD rule is similar to the previous
17726 implementation of the bootstrap-temacs rule except that it
17727 makes use of the ESC_CFLAGS variable instead of the CFLAGS
17730 These changes, along with some changes to nt/configure.bat,
17731 nt/gmake.defs, and nt/nmake.defs, are required to extend my
17732 earlier fix to add support for --cflags and --ldflags options
17733 that include quotes so that it works whether make uses cmd or
17736 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
17738 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
17739 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
17741 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
17742 a string. Handle both cases.
17743 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
17744 (Fdbus_register_method): Use Qinvalid_function.
17746 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
17748 * makefile.w32-in: Update dependencies.
17749 (LISP_H): Add inttypes.h and stdin.h.
17750 (PROCESS_H): Add unistd.h.
17752 2011-05-06 Eli Zaretskii <eliz@gnu.org>
17754 * lread.c: Include limits.h (fixes the MS-Windows build broken by
17755 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
17757 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
17759 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
17761 * term.c (vfatal): Remove stray call to va_end.
17762 It's not needed and the C Standard doesn't allow it here anyway.
17764 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
17765 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
17767 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
17770 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
17772 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
17774 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
17776 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
17778 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
17780 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
17781 * charset.c (Fdefine_charset_internal): Don't initialize
17782 charset.code_space[15]. The value was garbage, on hosts with
17783 32-bit int (Bug#8600).
17785 * lread.c (read_integer): Be more consistent with string-to-number.
17786 Use string_to_number to do the actual conversion; this avoids
17787 rounding errors and fixes some other screwups. Without this fix,
17788 for example, #x1fffffffffffffff was misread as -2305843009213693952.
17789 (digit_to_number): Move earlier, for benefit of read_integer.
17790 Return -1 if the digit is out of range for the base, -2 if it is
17791 not a digit in any supported base. (Bug#8602)
17793 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
17795 * dispnew.c (scrolling_window): Return 1 if we scrolled,
17796 to match comment at start of function. This also removes a
17797 GCC warning about overflow in a 32+64-bit port.
17799 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
17801 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
17802 Reported by Stefan Monnier in
17803 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
17804 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
17805 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
17807 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
17808 (EMACS_UINTPTR): Likewise, with uintptr_t.
17810 * lisp.h: Prefer 64-bit EMACS_INT if available.
17811 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
17812 on 32-bit hosts that have 64-bit int, so that they can access
17814 However, temporarily disable this change unless the temporary
17815 symbol WIDE_EMACS_INT is defined.
17817 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
17819 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
17820 This removes an assumption that EMACS_INT and long are the same
17821 width as pointers. The assumption is true for Emacs porting targets
17822 now, but we want to make other targets possible.
17823 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
17824 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
17825 In the rest of the code, change types of integers that hold casted
17826 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
17827 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
17828 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
17829 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
17830 No need to cast type when ORing.
17831 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
17832 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
17833 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
17834 assume EMACS_INT is the same width as char *.
17835 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
17836 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
17837 Remove no-longer-needed casts.
17838 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
17839 (xg_tool_bar_help_callback, xg_make_tool_item):
17840 Use EMACS_INTPTR to hold an integer
17841 that will be cast to void *; this can avoid a GCC warning
17842 if EMACS_INT is not the same width as void *.
17843 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
17844 * xdisp.c (display_echo_area_1, resize_mini_window_1):
17845 (current_message_1, set_message_1):
17846 Use a local to convert to proper width without a cast.
17847 * xmenu.c (dialog_selection_callback): Likewise.
17849 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
17850 Also, don't assume VALBITS / RAND_BITS is less than 5,
17851 and don't rely on undefined behavior when shifting a 1 left into
17853 * lisp.h (get_random): Change signature to match.
17855 * lread.c (hash_string): Use size_t, not int, for hash computation.
17856 Normally we prefer signed values; but hashing is special, because
17857 it's better to use unsigned division on hash table sizes so that
17858 the remainder is nonnegative. Also, size_t is the natural width
17859 for hashing into memory. The previous code used 'int', which doesn't
17860 retain enough info to hash well into very large tables.
17861 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
17863 * dbusbind.c: Don't possibly lose pointer info when converting.
17864 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
17865 Use XPNTR rather than XHASH, so that the high-order bits of
17866 the pointer aren't lost when converting through void *.
17868 * eval.c (Fautoload): Don't double-shift a pointer.
17870 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
17872 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
17874 * gnutls.c (DEF_GNUTLS_FN):
17875 * image.c (DEF_IMGLIB_FN): Make function pointers static.
17877 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
17879 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
17882 2011-05-05 Eli Zaretskii <eliz@gnu.org>
17884 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
17885 New version that can reserve upto 2GB of heap space.
17887 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
17889 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
17891 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
17893 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
17894 `gnutls_certificate_set_x509_key_file'.
17896 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
17898 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
17899 Update dependencies.
17901 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
17903 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
17904 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
17905 Remove unused parameter `fildes'.
17906 * process.c (read_process_output, send_process): Don't pass it.
17908 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
17910 Fix previous change: the library cache is defined in w32.c.
17911 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
17912 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
17914 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
17916 Implement dynamic loading of GnuTLS on Windows.
17918 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
17919 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
17920 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
17923 * gnutls.c (Qgnutls_dll): Define.

17932 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
17933 (Fgnutls_available_p): New function.
17934 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.

17942 (w32_delayed_load): Move to w32.c.
17944 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
17946 * w32.c (QCloaded_from, Vlibrary_cache): Define.
17947 (w32_delayed_load): Move from image.c. When loading a library, record
17948 its filename in the :loaded-from property of the library id.
17949 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
17950 Initialize and staticpro them.
17951 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
17953 * process.c: Include lisp.h before w32.h, not after.
17954 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
17955 instead of gnutls_record_check_pending.
17957 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
17959 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
17961 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
17962 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
17965 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
17967 * xterm.c (x_set_frame_alpha): Do not set property on anything
17968 else than FRAME_X_OUTER_WINDOW (Bug#8608).
17970 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
17972 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
17974 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
17976 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
17977 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)

17983 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
17984 (Qgnutls_bootprop_callbacks_verify): Make static.
17986 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
17988 * callproc.c: Indentation fixup.
17990 * sysdep.c (wait_for_termination_1): Make static.
17991 (wait_for_termination, interruptible_wait_for_termination):
17992 Move after wait_for_termination_1.
17994 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
17996 * sysdep.c (interruptible_wait_for_termination): New function
17997 which is like wait_for_termination, but allows keyboard
18000 * callproc.c (Fcall_process): Add (:file "file") as an option for
18002 (Fcall_process_region): Ditto.
18004 2011-04-30 Eli Zaretskii <eliz@gnu.org>
18006 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
18007 rather than `XVECTOR (FOO)->size'.
18009 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
18010 inttypes.h, as a gnulib replacement is used if it not available in
18013 2011-04-21 Eli Zaretskii <eliz@gnu.org>
18015 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
18016 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
18017 of MOST_POSITIVE_FIXNUM. (Bug#8528)
18019 * coding.c (coding_alloc_by_realloc): Error out if destination
18020 will grow beyond MOST_POSITIVE_FIXNUM.
18021 (decode_coding_emacs_mule): Abort if there isn't enough place in
18022 charbuf for the composition carryover bytes. Reserve an extra
18023 space for up to 2 characters produced in a loop.
18024 (decode_coding_iso_2022): Abort if there isn't enough place in
18025 charbuf for the composition carryover bytes.
18027 2011-04-21 Eli Zaretskii <eliz@gnu.org>
18029 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
18030 aborting when %lld or %lll format is passed.
18031 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
18032 %llo or %llx format is passed. (Bug#8545)
18034 * window.c (window_scroll_line_based): Use a marker instead of
18035 simple variables to record original value of point. (Bug#7952)
18037 * doprnt.c (doprnt): Fix the case where a multibyte sequence
18038 produced by %s or %c overflows available buffer space. (Bug#8545)
18040 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
18042 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
18043 (SIZE_MAX): Move defn after all includes, as they might #define it.
18045 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
18047 * w32.c (init_environment): Warn about defaulting HOME to C:\.
18049 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
18051 * keyboard.c (Qdelayed_warnings_hook): Define.
18052 (command_loop_1): Run `delayed-warnings-hook'
18053 if Vdelayed_warnings_list is non-nil.
18054 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
18055 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
18057 2011-04-28 Eli Zaretskii <eliz@gnu.org>
18059 * doprnt.c (doprnt): Don't return value smaller than the buffer
18060 size if the message was truncated. (Bug#8545).
18062 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
18064 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
18065 (Fx_window_property): #if-0 the whole functions, not just the bodies.
18067 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
18069 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
18071 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
18073 * makefile.w32-in: Update dependencies.
18075 2011-04-27 Eli Zaretskii <eliz@gnu.org>
18077 Improve `doprnt' and its usage. (Bug#8545)
18078 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
18079 `format_end'. Remove support for %l as a conversion specifier.
18080 Don't use xrealloc. Improve diagnostics when the %l size modifier
18081 is used. Update the commentary.
18083 * eval.c (verror): Simplify calculation of size_t.
18085 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
18088 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
18090 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
18093 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
18095 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
18096 This makes this file independent of the recent pseudovector change.
18098 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
18100 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
18102 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
18103 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
18104 Remove unused local.
18105 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
18107 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
18108 GCC 4.6.0 optimizes based on type-based alias analysis.
18109 For example, if b is of type struct buffer * and v of type struct
18110 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
18111 != &v->size, and therefore "v->size = 1; b->size = 2; return
18112 v->size;" must therefore return 1. This assumption is incorrect
18113 for Emacs, since it type-puns struct Lisp_Vector * with many other
18114 types. To fix this problem, this patch adds a new type struct
18115 vectorlike_header that documents the constraints on layout of vectors
18116 and pseudovectors, and helps optimizing compilers not get fooled
18117 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
18118 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
18119 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
18121 (XSETPVECTYPE): Rewrite in terms of new macro.
18122 (XSETPVECTYPESIZE): New macro, specifying both type and size.
18123 This is a bit clearer, and further avoids the possibility of
18124 undesirable aliasing.
18125 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
18126 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
18127 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
18128 since Lisp_Subr is a special case (no "next" field).
18129 (ASIZE): Now uses header.size rather than size.
18130 All previous uses of XVECTOR (foo)->size replaced to use this macro,
18131 to avoid the hassle of writing XVECTOR (foo)->header.size.
18132 (struct vectorlike_header): New type.
18133 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
18134 object, to help avoid aliasing.
18135 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
18136 (SUBRP): Likewise, since Lisp_Subr is a special case.
18137 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
18138 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
18139 (struct Lisp_Hash_Table): Combine first two members into a single
18140 struct vectorlike_header member. All uses of "size" and "next" members
18141 changed to be "header.size" and "header.next".
18142 * buffer.h (struct buffer): Likewise.
18143 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
18144 * frame.h (struct frame): Likewise.
18145 * process.h (struct Lisp_Process): Likewise.
18146 * termhooks.h (struct terminal): Likewise.
18147 * window.c (struct save_window_data, struct saved_window): Likewise.
18148 * window.h (struct window): Likewise.
18149 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
18150 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
18151 * buffer.c (init_buffer_once): Likewise.
18152 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
18154 * process.c (Fformat_network_address): Use local var for size,
18157 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
18159 Make the Lisp reader and string-to-float more consistent (Bug#8525)
18160 * data.c (atof): Remove decl; no longer used or needed.
18161 (digit_to_number): Move to lread.c.
18162 (Fstring_to_number): Use new string_to_number function, to be
18163 consistent with how the Lisp reader treats infinities and NaNs.
18164 Do not assume that floating-point numbers represent EMACS_INT
18165 without losing information; this is not true on most 64-bit hosts.
18166 Avoid double-rounding errors, by insisting on integers when
18167 parsing non-base-10 numbers, as the documentation specifies.
18168 * lisp.h (string_to_number): New decl, replacing ...
18169 (isfloat_string): Remove.
18170 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
18171 (read1): Do not accept +. and -. as integers; this
18172 appears to have been a coding error. Similarly, do not accept
18173 strings like +-1e0 as floating point numbers. Do not report
18174 overflow for integer overflows unless the base is not 10 which
18175 means we have no simple and reliable way to continue.
18176 Break out the floating-point parsing into a new
18177 function string_to_number, so that Fstring_to_number parses
18178 floating point numbers consistently with the Lisp reader.
18179 (digit_to_number): Move here from data.c. Make it static inline.
18180 (E_CHAR, EXP_INT): Remove, replacing with ...
18181 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
18182 (string_to_number): New function, replacing isfloat_string.
18183 This function checks for valid syntax and produces the resulting
18184 Lisp float number too. Rework it so that string-to-number
18185 no longer mishandles examples like "1.0e+". Use strtoumax,
18186 so that overflow for non-base-10 numbers is reported only when
18187 there's no portable and simple way to convert to floating point.
18189 * textprop.c (set_text_properties_1): Rewrite for clarity,
18190 and to avoid GCC warning about integer overflow.
18192 * intervals.h (struct interval): Use EMACS_INT for members
18193 where EMACS_UINT might cause problems. See
18194 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
18195 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
18196 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
18198 (offset_intervals): Tell GCC not to worry about length overflow
18199 when negating a negative length.
18201 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
18202 (overrun_check_free): Likewise.
18204 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
18205 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
18208 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
18209 (gnutls_make_error): Rename local to avoid shadowing.
18210 (gnutls_emacs_global_deinit): ifdef out; not used.
18211 (Fgnutls_boot): Use const for pointer to readonly storage.
18212 Comment out unused local. Fix pointer signedness problems.
18214 * lread.c (openp): Don't stuff size_t into an 'int'.
18215 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
18216 about possible signed overflow.
18218 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
18219 (GDK_KEY_g): Don't define if already defined.
18220 (xg_prepare_tooltip): Avoid pointer signedness problem.
18221 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
18223 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
18224 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
18226 * xfns.c (Fx_window_property): Simplify a bit,
18227 to make a bit faster and to avoid GCC 4.6.0 warning.
18228 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
18230 * fns.c (internal_equal): Don't assume size_t fits in int.
18232 * alloc.c (compact_small_strings): Tighten assertion a little.
18234 Replace pEd with more-general pI, and fix some printf arg casts.
18235 * lisp.h (pI): New macro, generalizing old pEd macro to other
18236 conversion specifiers. For example, use "...%"pI"d..." rather
18237 than "...%"pEd"...".
18238 (pEd): Remove. All uses replaced with similar uses of pI.
18239 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
18240 * alloc.c (check_pure_size): Don't overflow by converting size to int.
18241 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
18242 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
18243 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
18244 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
18245 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
18247 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
18248 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
18249 * print.c (safe_debug_print, print_object): Likewise.
18250 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
18252 Use pI instead of if-then-else-abort. Use %p to avoid casts,
18253 avoiding the 0 flag, which is not portable.
18254 * process.c (Fmake_network_process): Use pI to avoid cast.
18255 * region-cache.c (pp_cache): Likewise.
18256 * xdisp.c (decode_mode_spec): Likewise.
18257 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
18258 behavior on 64-bit hosts with printf arg.
18259 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
18260 (x_stop_queuing_selection_requests): Likewise.
18261 (x_get_window_property): Don't truncate byte count to an 'int'
18264 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
18265 here, since it parses constructs like leading '-' and spaces,
18266 which are not wanted; and it overflows with large numbers.
18267 Instead, simply match F[0-9]+, which is what is wanted anyway.
18269 * alloc.c: Remove unportable assumptions about struct layout.
18270 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
18271 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
18272 (allocate_vectorlike, make_pure_vector): Use the new macros,
18273 plus offsetof, to remove unportable assumptions about struct layout.
18274 These assumptions hold on all porting targets that I know of, but
18275 they are not guaranteed, they're easy to remove, and removing them
18276 makes further changes easier.
18278 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
18279 This doesn't fix a bug but makes the code clearer.
18280 (string_overrun_cookie): Now const. Use initializers that
18281 don't formally overflow signed char, to avoid warnings.
18282 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
18283 can cause Emacs to crash when string overrun checking is enabled.
18284 (allocate_buffer): Don't assume sizeof (struct buffer) is a
18285 multiple of sizeof (EMACS_INT); it need not be, if
18286 alignof(EMACS_INT) < sizeof (EMACS_INT).
18287 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
18289 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

18318 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
18319 "cast to pointer from integer of different size".
18321 Improve doprnt and its use in verror. (Bug#8545)
18322 * doprnt.c (doprnt): Document the set of format control sequences
18323 supported by the function. Use SAFE_ALLOCA instead of always
18326 * eval.c (verror): Don't limit the buffer size at size_max-1, that
18327 is one byte too soon. Don't use xrealloc; instead xfree and
18330 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
18332 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the

18338 parameters of `gnutls-boot' and documented those parameters in the
18339 docstring. Start callback support.
18340 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
18341 unless a fatal error occurred. Call gnutls_alert_send_appropriate

18439 * callint.c (Fcall_interactively): When displaying error message
18440 about invalid control letter, pass the character's codepoint, not

18445 codepoint of an invalid character, to avoid displaying a bogus
18448 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
18449 `error', not SYMBOL_NAME itself.
18451 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for

18454 * charset.c (check_iso_charset_parameter): Fix incorrect argument
18455 to `error' in error message about FINAL_CHAR argument. Make sure
18456 FINAL_CHAR is a character, and use %c when it is passed as
18457 argument to `error'.
18459 2011-04-23 Eli Zaretskii <eliz@gnu.org>
18461 * s/ms-w32.h (localtime): Redirect to sys_localtime.
18463 * w32.c: Include <time.h>.

18523 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
18524 by pacifying GCC about it. Maybe it's time to retire it?
18525 * xfaces.c (USG, __TIMEVAL__): Likewise.
18527 * dispextern.h (struct redisplay_interface): Rename param
18528 to avoid shadowing.
18529 * termhooks.h (struct terminal): Likewise.
18530 * xterm.c (xembed_send_message): Likewise.
18532 * insdel.c (make_gap_smaller): Define only if
18533 USE_MMAP_FOR_BUFFERS || REL_ALLOC || DOUG_LEA_MALLOC.

18630 (bcmp_translate, regcomp, regexec, print_double_string)
18631 (group_in_compile_stack, re_search, re_search_2, regex_compile)
18632 (re_compile_pattern, re_exec): Declare arguments and local
18633 variables `size_t' and `ssize_t' and return values `regoff_t', as

18644 2011-04-16 Ben Key <bkey76@gmail.com>
18646 * nsfont.m: Fixed bugs in ns_get_family and
18647 ns_descriptor_to_entity that were caused by using free to
18648 deallocate memory blocks that were allocated by xmalloc (via
18649 xstrdup). This caused Emacs to crash when compiled with
18650 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
18651 --enable-checking=xmallocoverrun). xfree is now used to
18652 deallocate these memory blocks.
18654 2011-04-15 Paul Eggert <eggert@cs.ucla.edu>
18656 * sysdep.c (emacs_read): Remove unnecessary check vs MAX_RW_COUNT.

18666 (emacs_read, emacs_write): Remove check for negative size, as the
18667 Emacs source code has been audited now.
18668 * sysdep.c (MAX_RW_COUNT): New macro, to work around kernel bugs.
18669 (emacs_read, emacs_write): Use it.
18670 * process.c (send_process): Adjust to the new signatures of
18671 emacs_write and emacs_gnutls_write. Do not attempt to store
18672 a byte offset into an 'int'; it might overflow.
18673 See http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00483.html

18697 * font.c (Qopentype): Don't make static (used from w32uniscribe.c).
18699 2011-04-14 Paul Eggert <eggert@cs.ucla.edu>

19120 2011-04-13 Eli Zaretskii <eliz@gnu.org>
19122 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
19123 when at ZV. (Bug#8487)
19125 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
19127 * charset.c (Fclear_charset_maps): Use xfree instead of free.
19129 * keyboard.c (parse_tool_bar_item): Likewise.
19130 * sound.c (sound_cleanup, alsa_close): Likewise.
19131 * termcap.c (tgetent): Likewise.
19132 * xfns.c (x_default_font_parameter): Likewise.
19133 * xsettings.c (read_and_apply_settings): Likewise.
19135 * alloc.c (overrun_check_malloc, overrun_check_realloc)
19136 (overrun_check_free): Protoize.
19138 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
19140 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
19141 since callers should never pass a negative size.
19142 Change the signature to match that of plain 'read' and 'write'; see
19143 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
19144 * lisp.h: Update prototypes of emacs_write and emacs_read.
19146 2011-04-11 Eli Zaretskii <eliz@gnu.org>
19148 * xdisp.c (redisplay_window): Don't try to determine the character
19149 position of the scroll margin if the window start point w->startp
19150 is outside the buffer's accessible region. (Bug#8468)
19152 2011-04-10 Eli Zaretskii <eliz@gnu.org>
19154 Fix write-region and its subroutines for buffers > 2GB.
19155 * fileio.c (a_write, e_write): Modify declaration of arguments and
19156 local variables to support buffers larger than 2GB.
19157 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
19159 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
19160 argument, local variables, and return value.
19162 * lisp.h: Update prototypes of emacs_write and emacs_read.
19164 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
19166 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
19168 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
19170 Fix more problems found by GCC 4.6.0's static checks.
19172 * xdisp.c (vmessage): Use a better test for character truncation.
19174 * charset.c (load_charset_map): <, not <=, for optimization,
19175 and to avoid potential problems with integer overflow.
19176 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
19177 * casetab.c (set_identity, shuffle): Likewise.
19178 * editfns.c (Fformat): Likewise.
19179 * syntax.c (skip_chars): Likewise.
19181 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
19182 This also lets GCC 4.6.0 generate slightly better loop code.
19184 * callint.c (Fcall_interactively): <, not <=, for optimization.
19185 (Fcall_interactively): Count the number of arguments produced,
19186 not the number of arguments given. This is simpler and lets GCC
19187 4.6.0 generate slightly better code.
19189 * ftfont.c: Distingish more carefully between FcChar8 and char.
19190 The previous code passed unsigned char * to a functions like
19191 strlen and xstrcasecmp that expect char *, which does not
19192 conform to the C standard.
19193 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
19194 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
19195 char * when the C standard requires it.
19197 * keyboard.c (read_char): Remove unused var.
19199 * eval.c: Port to Windows vsnprintf (Bug#8435).
19200 Include <limits.h>.
19201 (SIZE_MAX): Define if the headers do not.
19202 (verror): Do not give up if vsnprintf returns a negative count.
19203 Instead, grow the buffer. This ports to Windows vsnprintf, which
19204 does not conform to C99. Problem reported by Eli Zaretskii.
19205 Also, simplify the allocation scheme, by avoiding the need for
19206 calling realloc, and removing the ALLOCATED variable.
19208 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
19210 Remove invocations of doprnt, as Emacs now uses vsnprintf.
19211 But keep the doprint source code for now, as we might revamp it
19212 and use it again (Bug#8435).
19213 * lisp.h (doprnt): Remove.
19214 * Makefile.in (base_obj): Remove doprnt.o.
19215 * deps.mk (doprnt.o): Remove.
19217 error: Print 32- and 64-bit integers portably (Bug#8435).
19218 Without this change, on typical 64-bit hosts error ("...%d...", N)
19219 was used to print both 32- and 64-bit integers N, which relied on
19220 undefined behavior.
19221 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
19222 * lisp.h (error, verror): Mark as printf-like functions.
19223 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
19224 Report overflow in size calculations when allocating printf buffer.
19225 Do not truncate output string at its first null byte.
19226 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
19227 Truncate the output at a character boundary, since vsnprintf does not
19229 * charset.c (check_iso_charset_parameter): Convert internal
19230 character to string before calling 'error', since %c now has the
19232 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
19233 overflow when computing char to be passed to 'error'. Do not
19234 pass Lisp_Object to 'error'; pass the integer instead.
19235 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
19236 formatted with plain %d.
19238 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
19240 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
19242 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
19244 * xterm.c (x_catch_errors): Remove duplicate declaration.
19246 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
19248 * xdisp.c, lisp.h (message_nolog): Remove; unused.
19250 2011-04-10 Jim Meyering <meyering@redhat.com>
19252 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
19253 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
19254 return ssize_t not "int", and use size_t as the buffer length.
19255 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
19256 * gnutls.h: Update declarations.
19257 * process.c (read_process_output): Use ssize_t, to match.
19258 (send_process): Likewise.
19260 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
19262 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
19264 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
19266 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
19267 Use unsigned char, to match FcChar8 type definition.
19269 * xterm.c (handle_one_xevent):
19270 * xmenu.c (create_and_show_popup_menu):
19271 * xselect.c (x_decline_selection_request)
19272 (x_reply_selection_request): Avoid type-punned deref of X events.
19274 2011-04-09 Eli Zaretskii <eliz@gnu.org>
19276 Fix some uses of `int' instead of EMACS_INT.
19277 * search.c (string_match_1, fast_string_match)
19278 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
19279 (scan_buffer, find_next_newline_no_quit)
19280 (find_before_next_newline, search_command, Freplace_match)
19281 (Fmatch_data): Make some `int' variables be EMACS_INT.
19283 * xdisp.c (display_count_lines): 3rd argument and return value now
19284 EMACS_INT. All callers changed.
19285 (pint2hrstr): Last argument is now EMACS_INT.
19287 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
19288 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
19289 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
19290 (decode_coding_utf_16, decode_coding_emacs_mule)
19291 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
19292 (decode_coding_ccl, decode_coding_charset)
19293 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
19294 (decode_coding_iso_2022, decode_coding_emacs_mule)
19295 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
19296 <char_offset, last_offset>: Declare EMACS_INT.
19297 (encode_coding_utf_8, encode_coding_utf_16)
19298 (encode_coding_emacs_mule, encode_invocation_designation)
19299 (encode_designation_at_bol, encode_coding_iso_2022)
19300 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
19301 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
19303 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
19304 (encode_invocation_designation): Last argument P_NCHARS is now
19306 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
19307 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
19309 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
19312 * ccl.c (Fccl_execute_on_string): Declare some variables
19315 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
19317 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
19319 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
19321 * process.c (Fformat_network_address): Doc fix.
19323 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
19325 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
19327 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
19329 * keyboard.c (read_char): Call Lisp function help-form-show,
19330 instead of using internal_with_output_to_temp_buffer.
19331 (Qhelp_form_show): New var.
19332 (syms_of_keyboard): Use DEFSYM macro.
19334 * print.c (internal_with_output_to_temp_buffer): Function deleted.
19336 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
19338 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
19340 * process.c (Flist_processes): Remove to Lisp.
19341 (list_processes_1): Delete.
19343 2011-04-06 Eli Zaretskii <eliz@gnu.org>
19345 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
19347 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
19349 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
19351 Fix more problems found by GCC 4.6.0's static checks.
19353 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
19355 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
19357 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
19359 * xdisp.c (vmessage): Mark as a printf-like function.
19361 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
19363 * sound.c (sound_warning): Don't crash if arg contains a printf format.
19365 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
19366 printf-like functions.
19367 (tiff_load): Add casts to remove these marks before passing them
19368 to system-supplied API.
19370 * eval.c (Fsignal): Remove excess argument to 'fatal'.
19372 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
19373 This avoids several warnings with gcc -Wstrict-overflow.
19374 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
19375 directly, rather than having caller test rule sign. This avoids
19376 some unnecessary tests.
19377 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
19378 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
19379 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
19381 * xfont.c (xfont_text_extents): Remove var that was set but not used.
19382 (xfont_open): Avoid unnecessary tests.
19384 * composite.c (composition_gstring_put_cache): Use unsigned integer.
19386 * composite.h, composite.c (composition_gstring_put_cache):
19387 Use EMACS_INT, not int, for length.

19390 breaking out part of COMPOSITION_DECODE_RULE.
19391 (COMPOSITION_DECODE_RULE): Use it.
19392 * composite.c (get_composition_id): Remove unused local vars,
19393 by using the new macro.
19395 * textprop.c (set_text_properties_1): Change while to do-while,
19396 since the condition is always true at first.
19398 * intervals.c (graft_intervals_into_buffer): Mark var as used.
19399 (interval_deletion_adjustment): Return unsigned value.
19402 * process.c (list_processes_1, create_pty, read_process_output):

19412 (update_syntax_table): Use unsigned instead of int.
19414 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
19415 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
19416 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
19418 * print.c (print_error_message): Avoid int overflow.
19420 * font.c (font_list_entities): Redo for clarity,
19421 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
19423 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
19424 (font_score): Avoid potential overflow in diff calculation.
19426 * fns.c (substring_both): Remove var that is set but not used.
19427 (sxhash): Redo loop for clarity and to avoid wraparound warning.
19429 * eval.c (funcall_lambda): Rename local to avoid shadowing.
19431 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
19432 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
19433 can always succeed if overflow has undefined behavior.
19435 * search.c (boyer_moore, wordify): Remove vars set but not used.
19436 (wordify): Omit three unnecessary tests.
19438 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
19439 All callers changed. This avoids the need for an unused var.
19441 * casefiddle.c (casify_region): Remove var that is set but not used.
19443 * dired.c (file_name_completion): Remove var that is set but not used.
19445 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
19447 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
19448 (Finsert_file_contents): Remove unnecessary code checking fd.
19450 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
19451 Check for integer overflow on size calculations.
19453 * buffer.c (Fprevious_overlay_change): Remove var that is set
19456 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
19457 Remove vars that are set but not used.
19458 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
19459 (timer_check_2): Mark vars as initialized.
19461 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
19463 * image.c (lookup_image): Remove var that is set but not used.
19464 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
19466 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
19467 that are set but not used.
19469 * xfns.c (make_invisible_cursor): Don't return garbage
19470 if XCreateBitmapFromData fails (Bug#8410).
19472 * xselect.c (x_get_local_selection, x_handle_property_notify):
19473 Remove vars that are set but not used.
19475 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
19476 (make_invisible_cursor): Initialize a possibly-uninitialized variable.

19485 (map_tty_color) [!defined MSDOS]: Likewise.
19487 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
19489 * coding.c: Remove vars that are set but not used.
19490 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
19491 All callers changed.
19492 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
19493 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
19494 (decode_coding_charset): Remove vars that are set but not used.
19496 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
19497 that is set but not used.
19499 * print.c (print_object): Remove var that is set but not used.
19501 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
19502 The gnulib version avoids calling malloc in the usual case,
19503 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
19504 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
19505 * filelock.c (current_lock_owner): Likewise.
19506 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
19507 * sysdep.c: Include allocator.h, careadlinkat.h.
19508 (emacs_no_realloc_allocator): New static constant.
19509 (emacs_readlink): New function.
19510 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
19511 ../lib/careadlinkat.h.
19513 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
19515 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
19516 first non-nil return value).
19518 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
19520 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
19521 if not defined (Bug#8403).
19523 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
19525 * xdisp.c (display_count_lines): Remove parameter `start',
19526 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
19527 (get_char_face_and_encoding): Remove parameter `multibyte_p',
19528 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

19530 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
19531 and thereabouts. All callers changed.
19532 (get_per_char_metric): Remove parameter `f', unused since
19533 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
19535 2011-04-02 Jim Meyering <meyering@redhat.com>
19537 do not dereference NULL upon failed strdup
19538 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
19539 (ns_get_family): Likewise.
19541 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
19543 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
19545 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
19547 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or

19563 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
19565 (syms_of_lread): Declare `lexical-binding'.
19567 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
19569 * keyboard.c (eval_dyn): New fun.
19570 (menu_item_eval_property): Use it.
19572 * image.c (parse_image_spec): Use Ffunctionp.
19574 * fns.c (concat, mapcar1): Accept byte-code-functions.
19576 * eval.c (Fsetq): Handle lexical vars.
19577 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
19578 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
19579 (FletX, Flet): Obey lexical binding.
19580 (Fcommandp): Handle closures.
19581 (Feval): New `lexical' arg.
19582 (eval_sub): New function extracted from Feval. Use it almost
19583 everywhere where Feval was used. Look up vars in lexical env.
19585 (Ffunctionp): Move from subr.el.
19586 (Ffuncall): Handle closures.
19587 (apply_lambda): Remove `eval_flags'.
19588 (funcall_lambda): Handle closures and new byte-code-functions.
19589 (Fspecial_variable_p): New function.
19590 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
19591 but without exporting it to Lisp.
19593 * doc.c (Fdocumentation, store_function_docstring):
19594 * data.c (Finteractive_form): Handle closures.
19596 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
19599 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
19601 (exec_byte_code): New function extracted from Fbyte_code to handle new
19602 calling convention for byte-code-functions. Add new byte-codes.
19604 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
19606 * alloc.c (Fmake_symbol): Init new `declared_special' field.
19608 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
19610 * xdisp.c (redisplay_internal): Fix prototype.
19612 2011-03-31 Eli Zaretskii <eliz@gnu.org>
19614 * xdisp.c (SCROLL_LIMIT): New macro.
19615 (try_scrolling): Use it when setting scroll_limit.
19616 Limit scrolling to 100 screen lines.
19617 (redisplay_window): Even when falling back on "recentering",
19618 position point in the window according to scroll-conservatively,
19619 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
19621 (try_scrolling): When point is above the window, allow searching
19622 as far as scroll_max, or one screenful, to compute vertical
19623 distance from PT to the scroll margin position. This prevents
19624 try_scrolling from unnecessarily failing when
19625 scroll-conservatively is set to a value slightly larger than the
19626 window height. Clean up the case of PT below the margin at bottom
19627 of window: scroll_max can no longer be INT_MAX. When aggressive
19628 scrolling is in use, don't let point enter the opposite scroll
19629 margin as result of the scroll.
19630 (syms_of_xdisp) <scroll-conservatively>: Document the
19631 threshold of 100 lines for never-recentering scrolling.
19633 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
19635 * dispextern.h (move_it_by_lines):
19636 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
19637 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
19638 (message_log_check_duplicate): Remove parameters `prev_bol' and
19639 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
19640 (redisplay_internal): Remove parameter `preserve_echo_area',
19641 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
19643 * indent.c (Fvertical_motion):
19644 * window.c (window_scroll_pixel_based, Frecenter):
19645 Don't pass `need_y_p' to `move_it_by_lines'.
19647 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
19649 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
19650 steal a few bits to be more compact.
19651 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
19652 Remove unneeded casts.
19654 * bytecode.c (Fbyte_code): CAR and CDR can GC.
19656 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
19658 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
19659 binding" message (bug#7967).
19661 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
19663 Fix more problems found by GCC 4.6.0's static checks.
19665 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
19666 Remove unused local var.
19668 * editfns.c (Fmessage_box): Remove unused local var.
19670 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
19671 (note_mode_line_or_margin_highlight, note_mouse_highlight):
19672 Omit unused local vars.
19673 * window.c (shrink_windows): Omit unused local var.
19674 * menu.c (digest_single_submenu): Omit unused local var.
19675 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
19676 Omit unused local var.
19678 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
19679 Don't assume string length fits in int.
19680 (keyremap_step, read_key_sequence): Use size_t for sizes.
19681 (read_key_sequence): Don't check last_real_key_start redundantly.
19683 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
19684 instead of alloca (Bug#8344).
19686 * eval.c (Fbacktrace): Don't assume nargs fits in int.
19687 (Fbacktrace_frame): Don't assume nframes fits in int.
19689 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
19691 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
19694 * term.c (produce_glyphless_glyph): Remove unnecessary test.
19696 * cm.c (calccost): Turn while-do into do-while, for clarity.
19698 * keyboard.c (syms_of_keyboard): Use the same style as later
19699 in this function when indexing through an array. This also
19700 works around GCC bug 48267.
19702 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
19704 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
19706 * chartab.c (sub_char_table_ref_and_range): Redo for slight
19707 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
19709 * keyboard.c, keyboard.h (num_input_events): Now size_t.
19710 This avoids undefined behavior on integer overflow, and is a bit
19711 more convenient anyway since it is compared to a size_t variable.
19713 Variadic C functions now count arguments with size_t, not int.
19714 This avoids an unnecessary limitation on 64-bit machines, which
19715 caused (substring ...) to crash on large vectors (Bug#8344).
19716 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
19717 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
19718 All variadic functions and their callers changed accordingly.
19719 (struct gcpro.nvars): Now size_t, not int. All uses changed.

19721 * editfns.c (general_insert_function): Likewise.
19722 * eval.c (struct backtrace.nargs, interactive_p)
19723 (internal_condition_case_n, run_hook_with_args, apply_lambda)
19724 (funcall_lambda, mark_backtrace): Likewise.
19725 * fns.c (concat): Likewise.
19726 * frame.c (x_set_frame_parameters): Likewise.
19727 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
19728 0 if not found, not -1. All callers changed.
19730 * alloc.c (garbage_collect): Don't assume stack size fits in int.
19731 (stack_copy_size): Now size_t, not int.
19732 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
19734 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
19736 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
19737 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
19738 All callers changed.
19740 * lisp.h (multibyte_char_to_unibyte):
19741 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
19742 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
19743 * character.h (CHAR_TO_BYTE8):
19744 * cmds.c (internal_self_insert):
19745 * editfns.c (general_insert_function):
19746 * keymap.c (push_key_description):
19747 * search.c (Freplace_match):
19748 * xdisp.c (message_dolog, set_message_1): All callers changed.
19750 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
19752 * keyboard.c (safe_run_hook_funcall): New function.
19753 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
19754 don't set the hook to nil, but remove the offending function instead.
19755 (Qcommand_hook_internal): Remove, unused.
19756 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
19757 Vcommand_hook_internal.
19759 * eval.c (enum run_hooks_condition): Remove.
19760 (funcall_nil, funcall_not): New functions.
19761 (run_hook_with_args): Call each function through a `funcall' argument.
19762 Remove `cond' argument, now redundant.
19763 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
19764 (Frun_hook_with_args_until_failure): Adjust accordingly.
19765 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
19767 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
19769 * dispextern.h (string_buffer_position): Remove declaration.
19771 * print.c (strout): Remove parameter `multibyte', unused since
19772 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
19774 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
19775 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
19776 All callers changed.
19778 * w32.c (_wsa_errlist): Use braces for struct initializers.
19780 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
19781 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
19782 All callers changed.
19783 (string_buffer_position): Likewise. Also, make static (it's never
19784 used outside xdisp.c).
19785 (cursor_row_p): Remove parameter `w', unused since
19786 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.

19788 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
19789 All callers changed.
19791 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
19793 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.
19795 2011-03-27 Anders Lindgren <andlind@gmail.com>
19797 * nsterm.m (ns_menu_bar_is_hidden): New variable.
19798 (ns_constrain_all_frames, ns_menu_bar_should_be_hidden)
19799 (ns_update_auto_hide_menu_bar): New functions.
19800 (ns_update_begin): Call ns_update_auto_hide_menu_bar.

19804 (syms_of_nsterm): DEFVAR ns-auto-hide-menu-bar, init to Qnil.
19806 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
19808 * nsmenu.m (runDialogAt): Remove argument to timer_check.
19810 2011-03-27 Glenn Morris <rgm@gnu.org>
19812 * syssignal.h: Replace RETSIGTYPE with void.
19813 * atimer.c, data.c, dispnew.c, emacs.c, floatfns.c, keyboard.c:
19814 * keyboard.h, lisp.h, process.c, sysdep.c, xterm.c:
19815 Replace SIGTYPE with void everywhere.
19816 * s/usg5-4-common.h (SIGTYPE): Remove definition.
19817 * s/template.h (SIGTYPE): Remove commented out definition.
19819 2011-03-26 Eli Zaretskii <eliz@gnu.org>
19821 * xdisp.c (redisplay_window): Don't check buffer's clip_changed
19822 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
19824 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
19826 * w32.c (read_unc_volume): Use parameter `henum', instead of
19827 global variable `wget_enum_handle'.
19829 * keymap.c (describe_vector): Remove parameters `indices' and
19830 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.
19831 (describe_map, Fdescribe_vector): Adjust calls to `describe_vector'.
19833 * keyboard.h (timer_check, show_help_echo): Remove unused parameters.
19835 * keyboard.c (timer_check): Remove parameter `do_it_now',
19836 unused since 1996-04-12T06:01:29Z!rms@gnu.org.
19837 (show_help_echo): Remove parameter `ok_to_overwrite_keystroke_echo',
19838 unused since 2008-04-19T19:30:53Z!monnier@iro.umontreal.ca.
19840 * keyboard.c (read_char):
19841 * w32menu.c (w32_menu_display_help):
19842 * xmenu.c (show_help_event, menu_help_callback):
19843 Adjust calls to `show_help_echo'.
19845 * gtkutil.c (xg_maybe_add_timer):
19846 * keyboard.c (readable_events):
19847 * process.c (wait_reading_process_output):
19848 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
19850 * insdel.c (adjust_markers_gap_motion):
19851 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.
19852 (gap_left, gap_right): Don't call it.
19854 2011-03-25 Chong Yidong <cyd@stupidchicken.com>

19898 2011-03-24 Juanma Barranquero <lekktu@gmail.com>
19900 * w32term.c (x_set_glyph_string_clipping):
19901 Don't pass uninitialized region to CombineRgn.
19903 2011-03-23 Juanma Barranquero <lekktu@gmail.com>
19905 * w32fns.c (x_set_menu_bar_lines): Remove unused variable `olines'.
19906 (w32_wnd_proc): Pass NULL to Windows API, not uninitialized buffer.
19907 (Fx_close_connection): Remove unused variable `i'.
19909 * w32font.c (w32font_draw): Return number of glyphs.
19910 (w32font_open_internal): Remove unused variable `i'.

19923 (uniscribe_font_driver): Add missing initializers.
19925 2011-03-23 Julien Danjou <julien@danjou.info>
19927 * term.c (Fsuspend_tty, Fresume_tty):
19928 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
19929 * window.c (temp_output_buffer_show):
19930 * insdel.c (signal_before_change):
19931 * frame.c (Fhandle_switch_frame):
19932 * fileio.c (Fdo_auto_save):
19933 * emacs.c (Fkill_emacs):
19934 * editfns.c (save_excursion_restore):
19935 * cmds.c (internal_self_insert):
19936 * callint.c (Fcall_interactively):
19937 * buffer.c (Fkill_all_local_variables):
19938 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
19940 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
19941 unconditionally since it does the check itself.
19943 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
19945 Fix more problems found by GCC 4.5.2's static checks.
19947 * coding.c (encode_coding_raw_text): Avoid unnecessary test
19948 the first time through the loop, since we know p0 < p1 then.
19949 This also avoids a gcc -Wstrict-overflow warning.
19951 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
19952 leading to a memory leak, possible in functions like
19953 load_charset_map_from_file that can allocate an unbounded number
19954 of objects (Bug#8318).
19956 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
19957 that could (at least in theory) be that large.
19959 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
19960 This is less likely to overflow, and avoids undefined behavior if
19961 overflow does occur. All callers changed. Use strtoul to scan
19962 for the unsigned long integer.
19963 (pint2hrstr): Simplify and tune code slightly.
19964 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
19966 * scroll.c (do_scrolling): Work around GCC bug 48228.
19967 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
19969 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
19970 This also avoids a warning with gcc -Wstrict-overflow.
19971 (validate_x_resource_name): Simplify count usage.
19972 This also avoids a warning with gcc -Wstrict-overflow.
19974 * fileio.c (Fcopy_file): Report error if fchown or fchmod
19977 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
19979 * process.c (Fmake_network_process): Use socklen_t, not int,
19980 where POSIX says socklen_t is required in portable programs.
19981 This fixes a porting bug on hosts like 64-bit HP-UX, where
19982 socklen_t is wider than int (Bug#8277).
19983 (Fmake_network_process, server_accept_connection):
19984 (wait_reading_process_output, read_process_output):
19987 * process.c: Rename or move locals to avoid shadowing.
19988 (list_processes_1, Fmake_network_process):
19989 (read_process_output_error_handler, exec_sentinel_error_handler):
19990 Rename or move locals.
19991 (Fmake_network_process): Define label "retry_connect" only if needed.
19992 (Fnetwork_interface_info): Fix pointer signedness.
19993 (process_send_signal): Add cast to avoid pointer signedness problem.
19994 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
19995 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
19997 Make tparam.h and terminfo.c consistent.
19998 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
19999 Include tparam.h instead, since it declares them.

20059 clobbering (Bug#8298).
20060 * sysdep.c (sys_subshell): Likewise.
20061 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
20063 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
20064 This should get cleaned up, so that child_setup has the
20065 same signature on all platforms.
20067 * callproc.c (call_process_cleanup): Now static.
20068 (relocate_fd): Rename locals to avoid shadowing.

20229 (Fmemory_limit): Cast sbrk's returned value to char *.
20231 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this

20239 to use the following functions instead of these macros.
20240 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
20241 EMACS_INT, since callers assume the returned value fits in int.
20242 (upcase1): Likewise, for UPCASE_TABLE.
20243 (uppercasep, lowercasep, upcase): New static inline functions.
20244 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

20254 (regex_compile, re_match_2_internal): Mark locals as initialized.
20255 (RETALLOC_IF): Define only if needed.
20256 (WORDCHAR_P): Likewise. This one is never needed, but is used
20257 only in a comment talking about a compiler bug, so put inside
20258 the #if 0 of that comment.
20259 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
20260 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

20287 New macros, so that the caller can use some names other than
20288 gcpro1, gcpro2, etc.
20289 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
20291 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
20292 argument, for consistency with GCPRO2_VAR, etc: it is now the
20293 prefix of the variable, not the variable itself. All uses
20295 * dired.c (directory_files_internal, file_name_completion):
20296 Rename locals to avoid shadowing.
20298 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
20299 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
20300 dired.c's scmp function, had undefined behavior.
20301 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
20302 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
20303 * buffer.h: ... to here, because these macros use current_buffer,
20304 and the new implementation with inline functions needs to have
20305 current_buffer in scope now, rather than later when the macros
20307 (downcase, upcase1): New static inline functions.
20308 (DOWNCASE, UPCASE1): Reimplement using these functions.
20309 This avoids undefined behavior in expressions like
20310 DOWNCASE (x) == DOWNCASE (y), which previously suffered
20311 from race conditions in accessing the global variables
20312 case_temp1 and case_temp2.
20313 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
20314 * lisp.h (case_temp1, case_temp2): Remove their decls.
20315 * character.h (ASCII_CHAR_P): Move from here ...

20328 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
20330 (Fset_file_times, Finsert_file_contents, auto_save_error):

20337 * marker.c (bytepos_to_charpos): Remove; unused.
20339 * lisp.h (verify_bytepos, count_markers): New decls,
20340 so that gcc does not warn that these functions aren't declared.

20343 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.

20350 * buffer.c (fix_overlays_before): Mark locals as initialized.
20351 (fix_start_end_in_overlays): Likewise. This function should be
20352 simplified by using pointers-to-pointers, but that's a different

20355 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
20356 (report_overlay_modification): Rename locals to avoid shadowing.

20361 to suppress a gcc -Wclobbered warning that does not seem to be right.
20362 (MAXPATHLEN): Define only if needed.
20364 * process.c (serial_open, serial_configure): Move decls from here ...
20365 * systty.h: ... to here, so that they can be checked.
20367 * fns.c (get_random, seed_random): Move extern decls from here ...
