12 (Fset_window_configuration): Adjust accordingly.
13 * print.c (syms_of_print): Initialize debugging output not here...
14 (init_print_once): ...but in a new function here.
15 * lisp.h (init_print_once): Add prototype.

24 (freeze_window_starts): Use bool for booleans.
25 * window.h (window_frame_coordinates, resize_frame_windows)
26 (freeze_window_starts, set_window_buffer): Adjust prototypes.
28 2013-03-17 Stefan Monnier <monnier@iro.umontreal.ca>

50 Use getFilename and getDirectory.
51 (getFilename, getDirectory): New methods for EmacsSavePanel and
53 (ok:): In EmacsOpenPanel, if we can't choose directories, just return.

71 source bytes directly.
72 (produce_chars): Call insert_from_gap with the new arg 0.
73 (encode_coding): Likewise.
74 (decode_coding_gap): Control ASCII optimization by the variable

95 2013-03-14 Eli Zaretskii <eliz@gnu.org>
97 * w32term.c (w32_read_socket) <WM_WINDOWPOSCHANGED>: Remove old
98 and incorrect code. Treat WM_WINDOWPOSCHANGED like WM_ACTIVATE
100 (w32fullscreen_hook): If the frame is visible, reset
101 f->want_fullscreen flag after changing the frame size. If the
102 frame is not visible, set f->want_fullscreen to FULLSCREEN_WAIT.
105 2013-03-13 Daniel Colascione <dancol@dancol.org>
107 * emacs.c (main): Call syms_of_cygw32 on CYGWIN non-NTGUI builds
108 too so that these builds can use Cygwin's file conversion
109 functions. (We've been building and linking cygw32.o all along
110 and just not using it.)
112 2013-03-13 Paul Eggert <eggert@cs.ucla.edu>
114 File synchronization fixes (Bug#13944).
115 * Makefile.in (LIB_FDATASYNC): New macro.
117 * conf_post.h (BSD_SYSTEM, BSD_SYSTEM_AHB): Remove; no longer needed.
118 * fileio.c (Fwrite_region, write_region_inhibit_fsync):
119 Don't worry about HAVE_FSYNC, since a substitute fsync is
120 available if the system lacks one.
121 (Fwrite_regin): Retry fsync if interrupted.
123 2013-03-13 Eli Zaretskii <eliz@gnu.org>
125 * w32term.c (w32_read_socket): If the Emacs frame is being
126 activated, call w32fullscreen_hook, to make sure the new frame
127 dimensions are in effect. (Bug#13937)
129 2013-03-13 Dmitry Antipov <dmantipov@yandex.ru>
131 * xdisp.c (init_iterator): Simplify because both character and byte
132 positions are either specified or -1. Add eassert. Adjust comment.
133 * window.c (Fscroll_other_window): Use SET_PT_BOTH because both
134 character and byte positions can be obtained from marker.
136 2013-03-13 Paul Eggert <eggert@cs.ucla.edu>

151 a function pointer type; the C Standard requires this.
153 * sysdep.c: Remove a use of BSD_SYSTEM, which I'm trying to phase out.
154 Include <sys/param.h> unconditionally, as that works elsewhere and
155 is simpler here. Include <sys/sysctl.h> if DARWIN_OS ||
156 __FreeBSD__, not if BSD_SYSTEM, since it's needed only for Darwin
159 2013-03-11 Paul Eggert <eggert@cs.ucla.edu>
161 * insdel.c (adjust_after_replace): Use bool for boolean.
163 2013-03-11 Stefan Monnier <monnier@iro.umontreal.ca>

188 common file dialog code.
190 * w32fns.c (Ffile_system_info): Remove from cygw32 builds, which
191 can just use du like other systems.
193 * coding.c (from_unicode_buffer): Declare.

235 * insdel.c (adjust_after_replace): Make it public. New arg
237 (adjust_after_insert): Call adjust_after_replace with the new arg
240 2013-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
242 * keyboard.h (EVENT_START, EVENT_END, POSN_WINDOW, POSN_POSN)
243 (POSN_WINDOW_POSN, POSN_TIMESTAMP): Be careful since events may come
244 from Elisp via unread-command-events.
246 * keyboard.c (access_keymap_keyremap): Accept nil return value from
247 functions to mean "no change".
249 2013-03-08 Paul Eggert <eggert@cs.ucla.edu>
251 region-cache.c, scroll.c, search.c: Use bool for booleans.

254 * search.c (struct regexp_cache, compile_pattern_1)
255 (compile_pattern, string_match_1, search_command)
256 (trivial_regexp_p, search_buffer, Freplace_match, match_limit)
257 (search_regs_saved, Fregexp_quote):
258 Use bool for boolean.
259 * region-cache.c (region_cache_forward, region_cache_backward):
260 Fix comments to match code: these functions return int, not boolean.
262 2013-03-08 Dmitry Antipov <dmantipov@yandex.ru>
264 * search.c (find_newline): Accept start and end byte positions
265 as arguments and allow -1 if not known.

267 * lisp.h (find_newline, find_newline_no_quit): Adjust prototype.
268 * bidi.c (bidi_find_paragraph_start): Pass byte position to

271 Adjust call to find_newline.
272 * indent.c (vmotion): Adjust calls to find_newline_no_quit.

275 * xdisp.c (back_to_previous_line_start, forward_to_next_line_start)
276 (get_visually_first_element, move_it_vertically_backward): Likewise.
277 Obtain byte position from the display iterator, where appropriate.
279 2013-03-08 Paul Eggert <eggert@cs.ucla.edu>

300 to match other functions accepting character and byte positions.
302 (bidi_resolve_explicit_1, bidi_level_of_next_char): Adjust users.

304 when you need just to move to the previous buffer position.
305 * xdisp.c (Fcurrent_bidi_paragraph_direction): Use DEC_BOTH.
307 2013-03-07 Eli Zaretskii <eliz@gnu.org>
309 * .gdbinit (prowlims): Display the enabled_p flag of the row.
311 2013-03-07 Dmitry Antipov <dmantipov@yandex.ru>
313 Avoid character to byte conversions in motion subroutines.
314 * indent.h (compute_motion, vmotion): Add byte position argument.
315 * indent.c (compute_motion): Use it and avoid CHAR_TO_BYTE.
317 (Fcompute_motion): Break long line. Adjust call to compute_motion.

380 2013-03-06 Paul Eggert <eggert@cs.ucla.edu>
382 Fix a build failure on OpenBSD 4.x and MirBSD (Bug#13881).
383 * sysdep.c (list_system_processes)
384 [BSD_SYSTEM && !DARWIN_OS && !__FreeBSD__]:
385 Make it a stub in this case; otherwise the build might fail,
386 and this code hasn't been tested on such hosts anyway.
387 Problem reported by Nelson H. F. Beebe in
388 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00021.html>
389 and analyzed by Jérémie Courrèges-Anglas in
390 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00062.html>.
392 2013-03-06 Dmitry Antipov <dmantipov@yandex.ru>
394 * lisp.h (find_next_newline_no_quit): Rename to find_next_newline.
395 * xdisp.c (back_to_previous_line_start, forward_to_next_line_start)
396 (get_visually_first_element, move_it_vertically_backward): Ajust users.

398 * indent.c (vmotion): Likewise.
400 2013-03-05 Paul Eggert <eggert@cs.ucla.edu>
402 FILE's lock is now always .#FILE and may be a regular file (Bug#13807).
403 * filelock.c: Include <c-ctype.h>.
404 (MAX_LFINFO): New top-level constant.
405 (lock_info_type): Remove members pid, boot_time. Add members at,
406 dot, colon. Change user member to be the entire buffer, not a
407 pointer. This allows us to handle the case where a foreign
408 pid or boot time exceeds the local range. All uses changed.
409 (LINKS_MIGHT_NOT_WORK): New constant.
410 (FREE_LOCK_INFO): Remove, as the pieces no longer need freeing.
411 (defined_WINDOWSNT): Remove.
412 (MAKE_LOCK_NAME, file_in_lock_file_name):
413 Always use .#FILE (not .#-FILE) for the file lock,
414 even if it is a regular file.
415 (rename_lock_file): New function.
416 (create_lock_file): Use it.
417 (create_lock_file, read_lock_data):
418 Prefer a symbolic link for the lock file, falling back on a
419 regular file if symlinks don't work. Do not try to create
420 symlinks on MS-Windows, due to security hassles. Stick with
421 POSIXish functions (open, read, write, close, fchmod, readlink, symlink,
422 link, rename, unlink, mkstemp) when creating locks, as a GNUish
423 host may be using a Windowsish file system, and cannot use
424 MS-Windows-only system calls. Fall back on mktemp if mkstemp
425 doesn't work. Don't fail merely because of a symlink-contents
426 length limit in the current file system; fall back on regular
427 files. Increase the symlink contents length limit to 8 KiB, this
428 should be big enough for any real use and doesn't crunch the
430 (create_lock_file, lock_file_1, read_lock_data):
431 Simplify allocation of lock file buffers now that they fit in 8 KiB.
432 (lock_file_1): Return error number, not bool. All callers changed.
433 (ELOOP): New macro, if not already defined.
434 (read_lock_data): Return size of lock file contents, not Lisp object.
435 All callers changed. Handle a race condition if some other process
436 replaces a regular-file lock with a symlink lock or vice versa,
437 while we're trying to read the lock.
438 (current_lock_owner): Parse contents more carefully, to help avoid
439 confusing a regular-file lock with some other application's use
440 of the file. Check for lock file contents being too long, or
441 not parsing correctly.
442 (current_lock_owner, lock_file):
443 Allow foreign pid and boot times that exceed the local range.
444 (current_lock_owner, lock_if_free, lock_file):
445 Simplify allocation of lock file contents.
446 * w32.c (sys_rename_replace): New function, containing most of
447 the contents of the old sys_rename.
448 (sys_rename): Use it.
449 (fchmod): New dummy function.
450 * w32.h (sys_rename_replace, fchmod): New decls.
452 2013-03-05 Eli Zaretskii <eliz@gnu.org>
454 * bidi.c (bidi_resolve_explicit_1): Don't call CHAR_TO_BYTE or
455 bidi_count_bytes, as the callers now arrange for bidi_it->charpos
456 to be in sync with bidi_it->bytepos. Suggested by Dmitry Antipov
457 <dmantipov@yandex.ru>.
459 2013-03-05 Dmitry Antipov <dmantipov@yandex.ru>
461 * composite.c (get_composition_id, fill_gstring_header):
462 Use make_uninit_vector where appropriate.
463 * font.c (Ffont_get_glyphs, build_style_table): Likewise.
464 * xselect.c (clean_local_selection_data): Likewise.
466 2013-03-04 Paul Eggert <eggert@cs.ucla.edu>
468 Fix misuse of ImageMagick that caused core dump (Bug#13846).
469 * image.c (imagemagick_load_image): Calculate height and width
470 after flattening the image, not before.
472 2013-03-04 Dmitry Antipov <dmantipov@yandex.ru>
474 * font.c (Ffont_get_glyphs): Use convenient LGLYPH_NEW.
475 * ftfont.c (ftfont_shape_by_flt): Likewise.
476 * w32uniscribe.c (uniscribe_shape): Likewise.
478 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
480 The lock for FILE is now .#FILE or .#-FILE (Bug#13807).
481 The old approach, which fell back on DIR/.#FILE.0 through
482 DIR/.#FILE.9, had race conditions that could not be easily fixed.
483 If DIR/.#FILE is a non-symlink file, Emacs now does not create a
484 lock file for DIR/FILE; that is, DIR/FILE is no longer partly
485 protected by a lock if DIR/.#FILE is a non-symlink file ("partly"
486 because the locking mechanism was never reliable in that case).
487 This patch fixes this and other bugs discovered by a code
488 inspection that was prompted by
489 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00531.html>.
490 Also, this patch switches to .#-FILE (not .#FILE) on MS-Windows,
491 to avoid interoperability problems between the MS-Windows and
492 non-MS-Windows implementations. MS-Windows and non-MS-Windows
493 instances of Emacs now ignore each others' locks.
494 * filelock.c (defined_WINDOWSNT): New constant.
495 (MAKE_LOCK_NAME, fill_in_lock_file_name):
496 Don't create DIR/.#FILE.0 through DIR/.#FILE.9. Instead, create
497 DIR/.#FILE symlinks on non-MS-Windows hosts, and DIR/.#-FILE
498 regular files on MS-Windows hosts.
499 (MAKE_LOCK_NAME, unlock_file, Ffile_locked_p):
500 Use SAFE_ALLOCA to avoid problems with long file names.
501 (MAX_LFINFO): Now a local constant, not a global macro.
502 (IS_LOCK_FILE): Remove.
503 (lock_file_1): Don't inspect errno if symlink call succeeds;
505 (lock_file): Document that this function can return if lock
507 (lock_file): Don't access freed storage.
509 2013-03-02 Andreas Schwab <schwab@linux-m68k.org>

513 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
515 * textprop.c: Use bool for booleans.
516 (validate_interval_range, Fadd_text_properties)
517 (Fremove_text_properties): Prefer bool to int when either works.
519 2013-03-02 Eli Zaretskii <eliz@gnu.org>
521 * textprop.c (Fadd_text_properties, Fremove_text_properties):
522 If the interval tree changes as a side effect of calling
523 modify_region, re-do processing starting from the call to
524 validate_interval_range. (Bug#13743)
526 2013-02-28 Eli Zaretskii <eliz@gnu.org>
528 * w32.c (sys_open): Don't reset the flags for FD in fd_info[].
531 2013-02-27 Eli Zaretskii <eliz@gnu.org>
533 * filelock.c (create_lock_file) [WINDOWSNT]: Use _sopen with
534 _SH_DENYRW flag, instead of emacs_open, to deny any other process
535 access to the lock file until it is written and closed.
538 2013-02-27 Paul Eggert <eggert@cs.ucla.edu>
540 * callint.c (Qcall_interactively):
541 * macros.c (Qexecute_kbd_macro):

548 2013-02-26 Paul Eggert <eggert@cs.ucla.edu>
550 Minor textprop integer cleanup.
551 * intervals.h, textprop.c (add_text_properties_from_list):
552 Return void, not int, since nobody uses the return value.
553 * textprop.c (validate_plist, add_properties, remove_properties)
554 (Fadd_text_properties):
555 Don't assume list length fits in int.
556 (interval_has_all_properties, interval_has_some_properties)
557 (interval_has_some_properties_list, add_properties, remove_properties)
558 (Fadd_text_properties, Fremove_text_properties)
559 (Fremove_list_of_text_properties, text_property_stickiness):
560 Use bool for booleans.
561 (Fadd_text_properties, Fremove_text_properties):
562 (Fremove_list_of_text_properties):
563 Reindent do-while as per GNU style.
565 2013-02-25 Eli Zaretskii <eliz@gnu.org>
567 Implement CLASH_DETECTION for MS-Windows.
569 * filelock.c [WINDOWSNT]: Include w32.h.
570 (MAKE_LOCK_NAME): Don't use 'lock', it clashes with MS runtime
571 function of that name. Up-case the macro arguments.
572 (IS_LOCK_FILE): New macro.
573 (fill_in_lock_file_name): Use IS_LOCK_FILE instead of S_ISLNK.
574 (create_lock_file): New function, with body extracted from
576 [WINDOWSNT]: Implement lock files by writing a regular file with
577 the lock information as its contents.
578 (read_lock_data): New function, on Posix platforms just calls
580 [WINDOWSNT]: Read the lock info from the file.
581 (current_lock_owner): Call read_lock_data instead of calling
582 emacs_readlinkat directly.
583 (lock_file) [WINDOWSNT]: Run the file name through
586 * w32proc.c (sys_kill): Support the case of SIG = 0, in which case
587 just check if the process by that PID exists.
589 * w32.c (sys_open): Don't reset the _O_CREAT flag if _O_EXCL is
590 also present, as doing so will fail to error out if the file
593 * makefile.w32-in ($(BLD)/filelock.$(O)): Depend on src/w32.h.
595 * textprop.c (Fadd_text_properties, Fremove_text_properties)
596 (Fremove_list_of_text_properties): Skip all of the intervals in
597 the region between START and END that already have resp. don't
598 have the requested properties, not just the first one.
599 Add assertions that the loop afterwards always modifies the
600 properties. (Bug#13743)
602 2013-02-25 Stefan Monnier <monnier@iro.umontreal.ca>
604 * callint.c (Fcall_interactively): Use the right lexical environment
605 for `interactive' specs (bug#13811).
606 * eval.c (Feval): Accept a lexical environment.
608 2013-02-25 Paul Eggert <eggert@cs.ucla.edu>
610 Simplify data_start configuration (Bug#13783).
611 This is a followon simplification to the fix for Bug#13650.
612 * Makefile.in (LD_FIRSTFLAG, LIB_GCC, CRT_DIR, LIB_STANDARD)
613 (START_FILES): Remove. All uses removed.
614 (otherobj): Remove $(VMLIMIT_OBJ), as it's now first.
615 (ALLOBJS): Move here from autodeps.mk, and with VMLIMITS_OBJ first.
616 (buildobj.h): Use it.
617 ($(ALLOBJS)): Depend on globals.h.
618 (temacs$(EXEEXT)): Use $(ALLOBJS).
619 * autodeps.mk (ALLOBJS): Move to Makefile.in.
620 * deps.mk (vm-limit.o):

623 * emacs.c (__do_global_ctors, __do_global_ctors_aux)
624 (__do_global_dtors, __CTOR_LIST__, __DTOR_LIST__)
625 [__GNUC__ && !ORDINARY_LINK]: Remove.
626 * mem-limits.h, pre-crt0.c: Remove.
627 * unexaix.c, unexcoff.c: Don't include mem-limits.h.

629 (make_hdr): Use DATA_START instead of start_of_data.
630 * vm-limit.c: Move most of mem-limits.h's contents here.
631 (data_start): New decl. It's OK if this is approximate,
632 so simplify-away some unnecessary exactness.
633 (POINTER): Remove; all uses removed.
634 (data_space_start): Now char *, to avoid casts.
635 (exceeds_lisp_ptr): New function, replacing the old
636 EXCEEDS_LISP_PTR macro. All uses changed.
637 (check_memory_limits): Simplify and remove casts.
638 (start_of_data) [!CANNOT_DUMP || !SYSTEM_MALLOC]: Remove.
639 (memory_warnings): Use data_start instead of start_of_data.

643 * xdisp.c (set_message): Only check for debug-on-message if STRING
644 is a string. (Bug#13797)
646 2013-02-24 Paul Eggert <eggert@cs.ucla.edu>
648 Fix regression introduced by July 10 filelock.c patch.
649 * filelock.c (fill_in_lock_file_name): Fix crash caused by the
650 2012-07-10 patch to this file. Reported by Eli Zaretskii in
651 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00533.html>
652 and diagnosed by Andreas Schwab in
653 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00534.html>.
655 2013-02-22 Paul Eggert <eggert@cs.ucla.edu>
657 Assume C89 or better.
658 * ralloc.c (SIZE, POINTER, NIL):
659 * vm-limit.c (POINTER):
660 Remove, replacing all uses with C89 equivalents. These old
661 symbols were present only for porting to pre-C89 platforms.
663 2013-02-22 Claudio Bley <claudio.bley@gmail.com>
665 * w32.c (emacs_gnutls_pull): Don't call 'select', and don't loop.
666 This avoids warning messages reported as part of Bug#13546.
668 2013-02-21 Ken Brown <kbrown@cornell.edu>
670 * sheap.c (report_sheap_usage): Fix arguments of message1_no_log.
672 2013-02-20 Stefan Monnier <monnier@iro.umontreal.ca>
674 * sheap.c (report_sheap_usage): Prefer message1_nolog.
676 * keyboard.c (Qcommand_execute): New var.
677 (command_loop_1, read_char): Use it.
678 (Fcommand_execute): Remove, replace by an Elisp implementation.
679 (syms_of_keyboard): Adjust accordingly.
681 2013-02-19 Daniel Colascione <dancol@dancol.org>
683 * sheap.c (report_sheap_usage): Use message, not message1, so
684 that we don't try to create a buffer while we're in the middle
685 of dumping Emacs. Explain why.
687 2013-02-20 Dmitry Antipov <dmantipov@yandex.ru>
689 * search.c (find_newline): Return byte position in bytepos.
691 (find_next_newline_no_quit, find_before_next_newline):
692 Add bytepos argument.

699 (get_visually_first_element, move_it_vertically_backward):
700 Adjust users and avoid calls to CHAR_TO_BYTE where appropriate.
702 2013-02-19 Eli Zaretskii <eliz@gnu.org>
704 * w32proc.c (new_child): Avoid leaking handles if the subprocess
705 resources were not orderly released.
707 2013-02-17 Eli Zaretskii <eliz@gnu.org>
709 * xdisp.c (x_draw_vertical_border): For a window that is neither
710 the leftmost nor the rightmost, redraw both the left and the right
711 vertical borders. (Bug#13723)
713 2013-02-17 Stefan Monnier <monnier@iro.umontreal.ca>

729 * frame.c (syms_of_frame): ... to here.
731 2013-02-16 Eli Zaretskii <eliz@gnu.org>
733 * w32.c (sys_chown): Remove unused function.
735 * w32term.c <input_signal_count>: Declare 'volatile'
736 unconditionally. (Bug#9066)
738 * w32.c (set_errno): Reset h_errno and don't set it to any other
739 value. Set errno instead.
740 (check_errno): Reset h_errno.
741 (sys_socket, socket_to_fd, sys_bind, sys_connect)
742 (sys_gethostname, sys_getservbyname, sys_getpeername)
743 (sys_shutdown, sys_setsockopt, sys_listen, sys_getsockname)
744 (sys_accept, sys_recvfrom, sys_sendto, fcntl, sys_read): Don't set

752 2013-02-15 Eli Zaretskii <eliz@gnu.org>
754 * keyboard.c (read_char): Fix calculation of auto-save time out
755 when auto-save-timeout is less than 4. (Bug#13720)
757 * w32proc.c (new_child): Free up to 2 slots of dead processes at a

762 (sys_shutdown, sys_setsockopt, sys_listen, sys_getsockname)
763 (sys_accept, sys_recvfrom, sys_sendto, fcntl): In case of failure,
764 make sure errno is set to an appropriate value. (Bug#13546)
765 (socket_to_fd): Add assertion against indexing fd_info[] with a
766 value that is out of bounds.
767 (sys_accept): If fd is negative, do not set up the child_process
768 structure for reading.
770 2013-02-15 Dmitry Antipov <dmantipov@yandex.ru>
772 * composite.c (fill_gstring_header): Remove useless prototype.

779 (get_overlay_arrow_glyph_row, display_mode_element):
780 (decode_mode_spec_coding, message3):
781 * xfaces.c (face_at_string_position): Use bool for booleans.
784 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
786 Fix AIX port (Bug#13650).
787 * lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]:
788 Fix bug introduced in 2012-07-27 change. DATA_SEG_BITS, if set,
789 was #undeffed earlier, so it cannot be used as a macro here.
790 Use the constant and not the macro.
792 2013-02-15 Eli Zaretskii <eliz@gnu.org>
794 * w32proc.c (new_child): If no vacant slots are found in
795 child_procs[], make another pass looking for slots whose process
796 has exited or died. (Bug#13546)
798 * w32.c (sys_pipe): When failing due to file descriptors above
799 MAXDESC, set errno to EMFILE.
800 (_sys_read_ahead): Update cp->status when failing to read serial
801 communications input, so that the status doesn't stay at
802 STATUS_READ_IN_PROGRESS. (Bug#13546)
804 2013-02-14 Jan Djärv <jan.h.d@swipnet.se>
806 * gtkutil.c (tb_size_cb): New function.
807 (xg_create_tool_bar): Connect size-allocate to tb_size_cb (Bug#13512).
809 2013-02-14 Stefan Monnier <monnier@iro.umontreal.ca>
811 * keyboard.c (active_maps): Fcurrent_active_maps expects a position, not
814 2013-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
816 * keyboard.c (syms_of_keyboard): Further tweaks of docstring.
818 2013-02-13 Dmitry Antipov <dmantipov@yandex.ru>
820 * font.c (font_range): Add pos_byte argument. Adjust comment
822 * font.h (font_range): Adjust prototype.
823 * composite.c (autocmp_chars): Pass byte position to font_range.
824 Break long line. Remove useless prototype and format comment.
826 2013-02-13 Glenn Morris <rgm@gnu.org>
828 * keyboard.c (input-decode-map, key-translation-map): Doc fixes.
830 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
832 Improve AIX port some more (Bug#13650).
833 With this, it should be as good as it was in 23.3, though it's
834 still pretty bad: the dumped emacs does not run. See Mark Fleishman in
835 http://lists.gnu.org/archive/html/help-gnu-emacs/2011-04/msg00287.html
836 * unexaix.c (start_of_text): Remove.
837 (_data, _text): Declare as char[], not int, as AIX manual suggests.
838 (bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
839 (orig_load_scnptr, orig_data_scnptr):
840 Now off_t, not long, since they are file offsets.
841 (make_hdr): Use _data, not start_of_data ().
842 This is the key part of the fix.
843 (make_hdr, unrelocate_symbols): Use off_t for file offsets.
844 (unrelocate_symbols): Cast pointers to intptr_t, not to ulong.
846 * pre-crt0.c (data_start): Initialize to 1.
847 This ports to compilers that optimize the external declaration
848 'int x = 0;' as if it were 'int x;' to shrink the executable.
850 Improve AIX port (Bug#13650).
851 This doesn't fix the bug, but it makes progress: Emacs builds now.
852 * unexaix.c: Include inttypes.h, stdarg.h.
853 (report_error, report_error_1): Mark as _Noreturn.
854 (report_error): Don't report the wrong errno.
855 (report_error_1): Now varargs. All callers changed.
856 (make_hdr): Use uintptr_t, not unsigned, when converting pointers
857 to unsigned. Don't use ADDR_CORRECT, as it no longer exists.
858 (write_ptr): Use %p to print address rather than %lx and a cast
859 to unsigned long. Grow buffer a bit, to be safer.
861 2013-02-13 Eli Zaretskii <eliz@gnu.org>
863 * bidi.c (bidi_resolve_neutral): After finding the next
864 non-neutral character, accept NEUTRAL_ON type as well, because
865 directional control characters, such as LRE and RLE, have their
866 type converted to that by bidi_resolve_weak. This avoids aborts
867 when LRE/RLE follows a run of neutrals.
868 (bidi_move_to_visually_next): Assert that return value of
869 bidi_peek_at_next_level is non-negative. Negative values will
872 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
874 Minor getenv-related fixes.
875 * callproc.c (Fcall_process_region) [!DOS_NT]:
876 Avoid unnecessary duplicate call to getenv.
877 * callproc.c (init_callproc):
878 * dispnew.c (init_display):
879 * sysdep.c (sys_subshell):
880 Omit unnecessary cast of getenv or egetenv.
882 2013-02-13 Juanma Barranquero <lekktu@gmail.com>
884 * makefile.w32-in ($(BLD)/filelock.$(O), $(BLD)/sysdep.$(O)):
887 2013-02-12 Eli Zaretskii <eliz@gnu.org>
889 * xdisp.c (redisplay_internal): Don't set w->region_showing to the
891 (display_line): Set w->region_showing to the value of
892 it->region_beg_charpos, not to -1. This fixes redisplay
893 optimization when cursor is moved up after M->. (Bug#13623)
895 (try_scrolling): Scroll text up more if point is too close to ZV
896 and inside the scroll margin. This makes sure point is moved
897 outside the scroll margin in these cases.
899 * window.h (struct window): region_showing can no longer be
902 2013-02-11 Paul Eggert <eggert@cs.ucla.edu>
904 Tune by using memchr and memrchr.
905 * doc.c (Fsnarf_documentation):
906 * fileio.c (Fsubstitute_in_file_name):
907 * search.c (find_newline, scan_newline):
908 * xdisp.c (pos_visible_p, display_count_lines):
909 Use memchr and memrchr rather than scanning byte-by-byte.
910 * search.c (find_newline): Rename from scan_buffer.
911 Omit first arg TARGET, as it's always '\n'. All callers changed.
913 Clean up read_key_sequence a tiny bit more.
914 * keyboard.c (read_char_x_menu_prompt) [HAVE_MENUS]:
915 (read_key_sequence): Remove unused locals.
917 2013-02-11 Stefan Monnier <monnier@iro.umontreal.ca>
919 Clean up read_key_sequence a bit; reread active keymaps after first event.
920 * keyboard.c (read_char, read_char_x_menu_prompt)
921 (read_char_minibuf_menu_prompt):
922 Replace nmaps+maps with a single `map' arg.
923 (follow_key): Operate on a single map.
924 (active_maps): New function.
925 (test_undefined): Also return true for nil bindings.
926 (read_key_sequence): Use active_maps to replace the arrays of keymaps with
927 a single (composed) keymap. Remember `first_event' to choose the right
928 set of active keymaps. Recompute the set of keymaps after receiving
929 the first event. Remove GOBBLE_FIRST_EVENT.
930 (syms_of_keyboard): Remove inhibit_local_menu_bar_menus.
931 * keyboard.h (read_char): Update declaration.
932 * lread.c (read_filtered_event): Adjust call to read_char.
934 2013-02-11 Eli Zaretskii <eliz@gnu.org>
936 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
937 Don't use the limitation on backwards movement when lines are truncated
938 in the window. (Bug#13675)
940 2013-02-11 Dmitry Antipov <dmantipov@yandex.ru>
942 * marker.c (set_marker_internal): If desired position is passed
943 as a marker, avoid call to buf_charpos_to_bytepos.
944 * window.c (Fset_window_point): Omit redundant type checking.
945 (Fset_window_start): Likewise. Format comment.
946 (window_scroll_pixel_based): Use set_marker_restricted_both
947 with character and byte positions obtained from an iterator.
948 (Fset_window_configuration): Use set_marker_restricted_both.
949 * xdisp.c (message_dolog): Likewise.
951 2013-02-10 Eli Zaretskii <eliz@gnu.org>
953 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
954 When text lines are longer than window's screen lines, don't move back
955 too far. This speeds up some redisplay operations. (Bug#13675)
957 2013-02-10 Dmitry Antipov <dmantipov@yandex.ru>
959 * syntax.c (scan_sexps_forward): Fix byte position calculation
960 Bug#13664 (a.k.a Bug#13667) introduced with 2013-02-08 change.

971 (sxhash_float): Return EMACS_UINT, for consistency with the other
973 * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
974 non-static inline function and therefore can't use static vars.
975 (SXHASH_REDUCE): Move here from fns.c, and make it inline.
976 * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
977 with the other hash functions.
979 2013-02-09 Eli Zaretskii <eliz@gnu.org>
981 * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
982 XXXXXX part of the temporary file pattern is not downcased even
983 when w32-downcase-file-names is non-nil. (Bug#13661)
985 * xdisp.c (decode_mode_spec): Remove handling of %t.
987 * msdos.c (careadlinkatcwd): Remove.
989 2013-02-08 Stefan Monnier <monnier@iro.umontreal.ca>
991 * lread.c (skip_dyn_bytes): New function (bug#12598).

1027 argument is known to be a vector.
1028 * fns.c (Flocale_info): Likewise for ASET.
1029 * xselect.c (selection_data_to_lisp_data): Likewise for ASET.
1030 * w32fns.c (w32_parse_hot_key): Likewise for ASIZE and AREF.
1032 2013-02-05 Jan Djärv <jan.h.d@swipnet.se>
1034 * nsmenu.m (update_frame_tool_bar): Check for negative tool bar
1037 * nsterm.h (HAVE_NATIVE_FS): Define if OSX => 10.7.

1042 (ns_last_use_native_fullscreen): New variable.
1043 (x_make_frame_visible): Replace NEW_STYLE_FS with isFullscreen.
1044 (x_set_window_size): Do not take title bar and tool bar into account
1045 if isFullscreen returns YES.
1046 (ns_fullscreen_hook): Replace NEW_STYLE_FS with isFullscreen.
1047 (check_native_fs): New function.

1065 (syms_of_nsterm): Add ns-use-native-fullscreen.
1067 2013-02-04 Paul Eggert <eggert@cs.ucla.edu>
1069 * fileio.c (Qchoose_write_coding_system): Now static.
1071 2013-02-04 Eli Zaretskii <eliz@gnu.org>
1073 * xdisp.c (window_buffer_changed): region_showing can be negative,
1074 which still means region is being displayed.
1075 (redisplay_internal): Resurrect code that forced redisplay of the
1076 whole window when showing region and the mark has changed.
1077 Record the new mark position to allow redisplay optimizations.
1078 (display_line): If it->region_beg_charpos is non-zero, set the
1079 window's region_showing member to -1. (Bug#13623) (Bug#13626)
1081 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
1082 not bitfield of 1 bit.
1084 2013-02-03 Daniel Colascione <dancol@dancol.org>
1086 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
1087 daemon mode works on cygw32 when Emacs is installed and not just
1090 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
1092 Avoid file time stamp bug on MS-Windows (Bug#13149).
1093 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
1094 as FAT32 doesn't update time stamps when truncating them.
1095 Also, check that a file time stamp is not a multiple of 100 ns;
1096 this should catch all instances of the problem on MS-Windows,
1097 as its native file system resolution is 100 ns or worse, and
1098 checking for a non-multiple of 100 ns should impose only a small
1099 overhead on systems with ns resolution.
1101 2013-02-02 Eli Zaretskii <eliz@gnu.org>
1103 Avoid encoding file names on MS-Windows when they need to be run
1104 through dostounix_filename.
1105 * w32.c (normalize_filename): Accept an additional argument
1106 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
1107 downcase it even if w32-downcase-file-names is non-nil.
1108 (dostounix_filename): Accept an additional argument MULTIBYTE and
1109 pass it to normalize_filename.
1110 (emacs_root_dir): Adjust.
1112 * msdos.h (dostounix_filename): Adjust prototype.
1114 * w32.h (dostounix_filename): Adjust prototype.
1116 * msdos.c (dostounix_filename): Accept an additional argument and
1118 (init_environment): Adjust callers of dostounix_filename.
1120 * fileio.c (Ffile_name_directory, file_name_as_directory)
1121 (directory_file_name, Fexpand_file_name)
1122 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
1124 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
1126 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
1127 variables, as egetenv is case-insensitive for DOS_NT.
1129 * dired.c (file_name_completion): Don't call Fdirectory_file_name
1130 with an encoded file name.
1132 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name):
1133 Adjust calls to dostounix_filename.
1135 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
1137 * unexw32.c (unexec): Adjust call to dostounix_filename.
1139 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
1141 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
1144 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
1147 * callproc.c (Fcall_process): Make sure program name in PATH and
1148 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
1149 is passed to exec/spawnve, which fails unless the file-name
1152 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
1153 even if w32-quote-process-args is nil.
1155 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
1157 Fix timestamp bug when write-region appends nothing (Bug#13149).
1158 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
1159 the file's time stamp doesn't change if Emacs happens to write nothing
1160 to the file, and on a buggy file system this could cause Emacs to
1161 incorrectly infer that the file system doesn't have the bug.
1162 Avoid this problem by inhibiting the inference in this case.
1164 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
1166 * window.h (struct window): Convert base_line_number, base_line_pos
1167 and column_number_displayed members from Lisp_Object to ptrdiff_t.

1177 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
1178 (try_scrolling, try_cursor_movement, redisplay_window)
1179 (try_window_reusing_current_matrix, try_window_id, display_line)
1180 (display_mode_lines, decode_mode_spec): Adjust users.
1181 * .gdbinit (pwinx): Do not print sequence_number.
1183 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
1185 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
1186 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
1187 * dired.c: Include <fcntl.h>.
1188 (open_directory): New function, which uses open and fdopendir
1189 rather than opendir. DOS_NT platforms still use opendir, though.

1191 (file_attributes): New function, with most of the old Ffile_attributes.
1192 (directory_files_internal, Ffile_attributes): Use it.
1193 (file_attributes, file_name_completion_stat): First arg is now fd,
1194 not dir name. All uses changed. Use fstatat rather than lstat +
1196 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
1197 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
1198 (emacs_readlinkat): New function, with much of the old
1199 Ffile_symlink_p, but with an fd argument for speed.
1200 It uses readlinkat rather than careadlinkatcwd, so that it
1201 need not assume the working directory.
1202 (Ffile_symlink_p): Use it.
1203 * filelock.c (current_lock_owner): Use emacs_readlinkat
1204 rather than emacs_readlink.
1205 * lisp.h (emacs_readlinkat): New decl.
1206 (READLINK_BUFSIZE, emacs_readlink): Remove.
1207 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
1208 (emacs_norealloc_allocator, emacs_readlink): Remove.
1209 This stuff is moved to fileio.c.
1210 * w32.c (fstatat, readlinkat): New functions.
1211 (careadlinkat): Don't check that fd == AT_FDCWD.

1221 2013-01-30 Eli Zaretskii <eliz@gnu.org>
1223 * w32.c (sys_open): Zero out the flags for the new file descriptor.
1224 (sys_close): Zero out the flags for the file descriptor before
1225 closing it. (Bug#13546)
1227 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
1228 (logon_network_drive, stat_worker, symlink, chase_symlinks):
1229 Use CharNextExA and CharPrevExA to iterate over file names encoded in
1232 * w32.c (w32_get_long_filename, init_environment, readlink):
1233 Support file names encoded in DBCS codepages.
1234 (readlink): Use the current file-name-coding-system, not the ANSI
1235 codepage, to decode and handle targets of symlinks.
1237 2013-01-28 Eli Zaretskii <eliz@gnu.org>
1239 * w32.c (opendir): Now accepts a 'const char *'.
1241 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>

1246 (Vredisplay_preemption_period): Likewise.
1247 (update_frame, update_single_window, update_window, update_frame_1):
1248 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
1249 used, following the 2012-06-22 change.

1253 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
1255 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>
1257 * font.c (num_fonts): Remove the leftover from old
1258 debugging code. Adjust comment style here and there.
1259 * insdel.c (insert_1): Remove.
1260 * lisp.h (insert_1): Remove prototype.
1261 * xdisp.c (message_dolog): Adjust users to call insert_1_both.
1263 2013-01-25 Eli Zaretskii <eliz@gnu.org>
1265 * w32.c (max_filename_mbslen): New function.
1266 (normalize_filename, readdir): Use it to detect locales where ANSI
1267 encoding of file names uses a double-byte character set (DBCS).
1268 If a DBCS encoding is used, advance by characters using
1269 CharNextExA, instead of incrementing a 'char *' pointer.
1270 Use _mbslwr instead of _strlwr. (Bug#13515)
1272 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
1273 request of memory reservation to 1.7GB. (Bug#13065)

1283 Avoid redundant calls to strlen.
1285 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
1287 Drop async_visible and async_iconified fields of struct frame.
1288 This is possible because async input is gone; for details, see
1289 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
1290 * frame.h (struct frame): Remove async_visible and async_iconified

1311 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
1313 * xdisp.c (message2, message2_nolog): Remove functions.
1314 (message3, message3_nolog): Extract nbytes and multibyteness directly
1315 from the string. Change all callers.
1316 (message3_nolog): Don't set message_enable_multibyte since set_message
1317 will reset it anyway.
1318 (message1, message1_nolog): Use message3.
1319 (vmessage): Use a stack allocated buffer rather than f->message_buf.
1320 (with_echo_area_buffer): Remove last two arguments. Update all callers.
1321 (set_message): Drop all but the second arg, which has to be a string.

1335 * editfns.c (message_text, message_length): Remove vars.
1336 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
1337 * fileio.c (auto_save_error): Use message3 instead of message2.

1368 * xdisp.c (mark_window_display_accurate): Simplify the loop
1369 assuming that the only one of vchild, hchild or buffer window
1370 slots is non-nil. Call mark_window_display_accurate_1 for
1371 the leaf windows only.

1385 set_file_security returns FALSE. Avoids spurious errors when
1388 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
1390 * fileio.c (Finsert_file_contents): Revert code introduced at
1391 2013-01-18 in favor of the simpler and generally better fix.
1392 Save stack space by removing 'buffer' and reusing 'read_buf'
1395 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1397 * lisp.h (eabs): Define unconditionally (Bug#13419).
1398 The old "#if !defined (eabs)" was an unnecessary revenant of back
1399 when this macro was called "abs". Document 'eabs' better.
1401 2013-01-19 Glenn Morris <rgm@gnu.org>
1403 * fns.c (Frandom): Doc fix.
1405 2013-01-19 Eli Zaretskii <eliz@gnu.org>

1417 * fileio.c: Use O_APPEND to append.
1418 This corresponds better to the natural interpretation of "append",
1419 and avoids the need to open the output file twice, or to invoke
1420 lseek when APPEND is neither nil nor a number.
1421 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
1422 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
1423 file possibly twice, and lseeking to its end; this avoids the
1424 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
1425 at the same time: the combination is never needed and apparently
1426 it doesn't work with DOS_NT.
1428 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
1429 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
1431 Allow floating-point file offsets.
1432 Problem reported by Vitalie Spinu in
1433 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
1434 * fileio.c (emacs_lseek): Remove.
1435 (file_offset): New function.
1436 (Finsert_file_contents, Fwrite_region): Use it.
1438 2013-01-19 Chong Yidong <cyd@gnu.org>
1440 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
1441 aborting on Fsignal (Bug#13289).
1443 2013-01-19 Eli Zaretskii <eliz@gnu.org>
1445 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
1446 set_file_security as failure due to insufficient privileges.
1447 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
1448 (fstat): Return owner and group like 'stat' and 'lstat' do.
1450 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1452 Work around bug in CIFS and vboxsf file systems (Bug#13149).
1453 The bug was observed on Ubuntu operating inside a virtual machine,
1454 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
1455 The workaround introduces a race condition on non-buggy hosts,
1456 but it's an unlikely race and anyway there's a nearly identical
1457 nearby race that can't be fixed.
1458 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
1460 (Fwrite_region): Test for file system time stamp bug.
1461 (init_fileio): New function.
1462 * lisp.h (init_fileio): Declare it.
1463 * emacs.c (main): Call it.

1471 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
1472 for the error description produced by valgrind.
1473 * fileio.c (read_non_regular): Rename to read_contents.
1474 Free Lisp_Save_Value object used to pass parameters.
1475 (read_non_regular_quit): Rename to read_contents_quit.
1476 (Finsert_file_contents): Redesign internal file reading loop to adjust
1477 gap and end positions after each read and so help make_gap to work
1478 properly. Do not signal an I/O error too early and so do not leave
1479 not yet decoded characters in a buffer, which was the reason of
1480 redisplay crash. Use list2 to build return value. Adjust comments.
1482 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
1484 Close a race when statting and reading files (Bug#13149).
1485 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
1486 This avoids a race if the file is renamed between stat and open.
1487 This race is not the problem originally noted in Bug#13149;
1488 see <http://bugs.gnu.org/13149#73> and later messages in the thread.

1533 * lisp.h (XSAVE_POINTER, XSAVE_INTEGER): Change to allow
1534 extraction from any Lisp_Save_Value slot. Add type checking.

1587 * editfns.c (save_excursion_save): Pack everything within
1588 Lisp_Save_Value and so avoid xmalloc.
1589 (save_excursion_restore): Adjust to match new layout. Use free_misc
1590 because we do not allocate extra memory any more. Add eassert.

1872 * fileio.c (file_name_as_directory, directory_file_name):
1873 Accept an additional argument MULTIBYTE to indicate whether the input C
1874 came from a multibyte or a unibyte Lisp string; all callers
1875 adjusted. Don't assume the input string is always multibyte.
1877 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
1878 don't ENCODE_FILE them, and return a unibyte string if the input
1880 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
1881 don't assume the input strings will always be multibyte. If the
1882 input strings are multibyte, decode strings obtained from C
1885 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
1887 * lisp.h (toplevel): Add two notices to the comment about
1888 defining a new Lisp data type.
1889 * print.c (print_object): If Lisp_Save_Value object's pointer
1890 is the address of a memory area containing Lisp_Objects, try
1892 * alloc.c (valid_lisp_object_p): Adjust comment.
1894 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
1896 * keyboard.c (record_asynch_buffer_change): Initialize an event
1897 only if it's really needed.
1898 * frame.h (enum output_method): Remove output_mac member since
1899 it's a leftover from the deleted code.
1900 * frame.c (Fframep): Adjust user here ...
1901 * terminal.c (Fterminal_live_p): ... and here.
1902 * coding.c (Qmac): Now here because it's only used to denote
1903 end-of-line encoding type.
1904 (syms_of_coding): DEFSYM it.
1905 * frame.h (Qmac): Remove duplicated declaration.
1907 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
1909 * window.c (select_window_1): Now static, since it's used only here.
1911 2012-12-25 Eli Zaretskii <eliz@gnu.org>
1913 * window.c (window_body_cols): Subtract display margins from the
1914 window body width on TTYs as well. See
1915 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
1916 for the original report.
1918 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
1920 * xdisp.c (redisplay_window): Remove inner local variable
1921 because the outer shadowed one has the same meaning.
1922 * xterm.h (struct x_output): Remove toolbar_detached member since it's
1924 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
1925 (xg_create_tool_bar): Adjust users.
1927 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
1929 * buffer.h (BUF_COMPACT): New macro to follow the common style.
1930 * buffer.c (Fget_buffer_create): Use it to set compact field of
1931 struct buffer_text to avoid accessing an uninitialized value
1932 when compact_buffer is called for the first time.
1933 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
1934 (Fset_buffer_modified_p): Use buffer_window_count to check
1935 whether the buffer is displayed in some window.
1936 * xdisp.c (message_dolog): Likewise.
1938 2012-12-23 Eli Zaretskii <eliz@gnu.org>
1940 * w32.c (acl_set_file): If setting the file security descriptor
1941 fails, and the new DACL is identical to the existing one, silently
1942 return success. This fixes problems for users backing up their
1943 own files without having the necessary privileges for setting
1944 security descriptors.
1946 * w32proc.c (reader_thread): Do not index fd_info[] with negative
1948 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
1949 after WaitForSingleObject returns normally. This expedites reader
1950 thread shutdown when delete_child triggers it.
1951 (reap_subprocess): More accurate commentary for why we call
1952 delete_child only when cp->fd is negative.
1954 * w32.c (sys_close): Do not call delete_child on a subprocess
1955 whose handle is not yet closed. Instead, set its file descriptor
1956 to a negative value, so that reap_subprocess will call
1957 delete_child on that subprocess when its SIGCHLD arrives.
1958 This avoids closing handles used for communications between sys_select
1959 and reader_thread, which doesn't give sys_select a chance to
1960 notice that the process exited and invoke the SIGCHLD handler for
1963 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
1965 * nsfns.m (Fns_do_applescript): Run event loop until script has
1966 been executed (Bug#12969).
1967 (ns_run_ascript): Chech as_script for nil, set to nil after
1970 2012-12-22 Martin Rudalics <rudalics@gmx.at>
1972 * window.c (Fselect_window): Reword doc-string (Bug#13248).
1974 2012-12-22 Eli Zaretskii <eliz@gnu.org>
1976 * w32term.c (w32fullscreen_hook): New function.
1977 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
1979 2012-12-21 Eli Zaretskii <eliz@gnu.org>
1981 * fileio.c (Finsert_file_contents): Doc fix.
1983 * w32proc.c (new_child, delete_child, find_child_pid): For a
1984 subprocess, consider its slot being in use as long as its process
1985 handle (procinfo.hProcess) is not NULL. This avoids reusing the
1986 slot when a new process is started immediately after killing
1987 another one, without waiting enough time for the first process to
1988 be reaped and resources allocated for it be orderly freed.
1990 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
1992 2012-12-21 Chong Yidong <cyd@gnu.org>
1994 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
1996 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
1998 2012-12-21 Eli Zaretskii <eliz@gnu.org>
2000 * w32.c (get_name_and_id): Always pass NULL as the first argument
2001 of lookup_account_sid. Avoids crashes with UNC file names that
2002 refer to DFS domains, not to specific machine names. (Bug#12621)
2003 Remove now unused argument FNAME; all callers changed.
2004 (get_file_owner_and_group): Remove now unused argument FNAME; all
2007 2012-12-21 Chong Yidong <cyd@gnu.org>
2009 * editfns.c (Finsert_char): Since read-char-by-name now signals an
2010 error for invalid chars, don't check for a nil return value.
2012 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
2014 Avoid calls to CHAR_TO_BYTE if byte position is known.
2015 * editfns.c (make_buffer_string_both): Use move_gap_both.
2016 (Fbuffer_string): Use make_buffer_string_both.
2017 * marker.c (buf_charpos_to_bytepos): Convert to eassert.
2019 (buf_bytepos_to_charpos): Likewise.
2020 (charpos_to_bytepos): Remove.
2021 * fileio.c (Finsert_file_contents): Use move_gap_both.
2022 * search.c (Freplace_match): Likewise.
2023 * process.c (process_send_region): Likewise. Use convenient
2024 names for byte positions.
2025 * lisp.h (charpos_to_bytepos): Remove prototype.
2026 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
2027 * insdel.c (move_gap): Likewise.
2029 2012-12-20 Paul Eggert <eggert@cs.ucla.edu>
2031 * xdisp.c (redisplay_internal): Remove now-unused local.
2033 2012-12-20 Stefan Monnier <monnier@iro.umontreal.ca>
2035 * xdisp.c (select_frame_for_redisplay, ensure_selected_frame): Remove.
2036 (redisplay_internal): Don't bother selecting the frame to get the
2037 proper value of frame-local variables (bug#13225).
2039 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
2041 * textprop.c (set_text_properties_1): Do not allow NULL interval.
2042 Rename 4th argument since it may be buffer or string. Adjust comment.
2043 * intervals.c (graft_intervals_info_buffer): Find an interval here.
2045 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
2047 * coding.c (Fdetect_coding_region): Do not check start and end with
2048 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
2049 (code_convert_region): Likewise.
2051 2012-12-18 Eli Zaretskii <eliz@gnu.org>
2053 * w32.c (acl_get_file, acl_set_file): Run the file name through
2054 map_w32_filename, and resolve any symlinks in the file name, like
2056 (acl_set_file): Call revert_to_self, if any privileges were
2059 2012-12-17 Juanma Barranquero <lekktu@gmail.com>
2061 * makefile.w32-in ($(BLD)/editfns.$(O), $(BLD)/fileio.$(O))
2062 ($(BLD)/w32.$(O)): Update dependencies.
2064 2012-12-17 Stefan Monnier <monnier@iro.umontreal.ca>
2066 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
2067 propagate redisplay's scrolling (if any) to the right window.
2068 (redisplay_internal): Use ensure_selected_frame.
2069 (display_mode_lines): Complete last fix.
2070 * window.c (select_window_1): New func, extracted from select_window.
2071 (select_window): Use it.
2072 * window.h (select_window_1): Declare.
2074 2012-12-17 Eli Zaretskii <eliz@gnu.org>
2076 Emulate Posix ACL APIs on MS-Windows.
2077 * w32.c: Include sddl.h and sys/acl.h.
2078 (SDDL_REVISION_1): Define if not already defined.
2079 (g_b_init_get_security_descriptor_dacl)
2080 (g_b_init_convert_sd_to_sddl, g_b_init_convert_sddl_to_sd)
2081 (g_b_init_is_valid_security_descriptor)
2082 (g_b_init_set_file_security): New static flags.

2093 (convert_sddl_to_sd, acl_valid, acl_to_text, acl_from_text)
2094 (acl_free, acl_get_file, acl_set_file): New functions.
2096 * fileio.c (Fcopy_file) [WINDOWSNT]: Support copying ACLs.
2098 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
2100 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
2101 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
2102 for some of that bug's symptoms can now cause Emacs to abort.
2103 Remove the workaround.
2104 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
2105 The bug that caused SIGCHLD to get lost has been fixed, and the
2106 workaround for it can now cause Emacs to abort.
2108 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
2110 * sysdep.c (emacs_abort): Bump backtrace size to 40.
2111 Companion to the 2012-09-30 patch. Suggested by Eli Zaretskii in
2112 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.
2114 2012-12-16 Romain Francoise <romain@orebokech.com>
2116 * fileio.c (Ffile_acl, Fset_file_acl): New functions.
2117 (Fcopy_file): Change last arg to `preserve_extended_attributes'
2118 and copy ACL entries of file in addition to SELinux context if set.
2119 (syms_of_fileio): Add `file-acl' and `set-file-acl'.
2121 * Makefile.in (LIBACL_LIBS): New macro.
2124 2012-12-15 Paul Eggert <eggert@cs.ucla.edu>
2126 * fileio.c (internal_delete_file): Use bool for boolean.
2128 2012-12-15 Eli Zaretskii <eliz@gnu.org>
2130 Fix bug #13079 on MS-Windows with temp files not being deleted.
2131 * w32.h (_child_process): New members input_file and
2133 (register_child): First argument is now pid_t.
2134 (record_infile, record_pending_deletion): New prototypes.
2136 * w32proc.c (new_child): Initialize input_file and
2137 pending_deletion members of the child.
2138 (delete_child): Delete the child's temporary input file, if any,
2139 that is pending deletion.
2140 (register_child): First argument is now pid_t.
2141 (record_infile, record_pending_deletion): New functions.
2142 (reap_subprocess): Fix a typo in DebPrint string.
2143 (sys_spawnve, sys_kill): Use pid_t for PID arguments.
2145 * fileio.c (internal_delete_file): Return an int again: non-zero
2146 if delete-file succeeds, zero otherwise.
2148 * lisp.h (internal_delete_file): Adjust prototype.
2150 * callproc.c (Fcall_process): Don't overwrite infile with result
2152 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
2153 asynchronous subprocess, record the name of the input file name,
2155 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
2156 delete the file, record it as pending deletion when the subprocess
2159 2012-12-14 Eli Zaretskii <eliz@gnu.org>
2161 * editfns.c [HAVE_PWD_H]: Include grp.h.
2163 * makefile.w32-in ($(BLD)/editfns.$(O)): Add $(NT_INC)/grp.h.
2165 2012-12-14 Paul Eggert <eggert@cs.ucla.edu>
2167 Fix permissions bugs with setgid directories etc. (Bug#13125)
2168 * dired.c (Ffile_attributes): Return t as the 9th attribute,
2169 to mark it as a placeholder. The old value was often wrong.
2170 The only user of this attribute has been changed to use
2171 file-ownership-preserved-p instead, with its new group arg.
2172 * editfns.c (Fgroup_gid, Fgroup_real_gid): New functions.
2174 2012-12-14 Stefan Monnier <monnier@iro.umontreal.ca>

2179 2012-12-14 Eli Zaretskii <eliz@gnu.org>
2181 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
2182 try to get accurate owner and group information from NT file
2183 security APIs. This is to make most callers of 'stat' and
2184 'lstat', which don't need that information, much faster.
2186 * dired.c (Ffile_attributes) [WINDOWSNT]:
2187 Set w32_stat_get_owner_group to a non-zero value, to request accurate
2188 owner and group information from 'lstat'.
2190 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
2192 * fileio.c (Finsert_file_contents): Don't put tail into head area,
2193 as that confuses set-auto-coding, so insist on the head-read
2194 returning the full 1024 bytes. Let lseek compute the tail offset;
2195 less work for us. Do not ignore I/O errors when reading the tail.
2197 * xdisp.c: Minor style fixes.
2198 (init_iterator): Hoist assignment out of if-expression.
2199 (markpos_of_region): Callers now test for sign, not for -1.
2201 2012-12-13 Dmitry Antipov <dmantipov@yandex.ru>
2203 Minor redisplay optimization when the region length is zero.
2204 * xdisp.c (markpos_of_region): New function.
2205 (init_iterator): Do not highlight the region of zero length.
2206 (redisplay_window): Check whether the region is of non-zero length.
2207 (try_cursor_movement): Allow if the region length is zero.
2208 (try_window_reusing_current_matrix, try_window_id): Likewise.
2210 2012-12-13 Eli Zaretskii <eliz@gnu.org>
2212 * search.c (search_buffer): Check the inverse translations of each
2213 character in pattern when the buffer being searched is unibyte.
2216 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
2218 * fileio.c (Fvisited_file_modtime): Return (-1 ...) for nonexistent
2219 files, fixing a regression from 24.2.
2220 (Fverify_visited_file_modtime): Don't read uninitialized st.st_size.
2222 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
2224 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
2225 fstat shouldn't fail, and if it does fail copy-file should not proceed.
2226 Remove unnecessary S_ISLNK test, as (contra the comments) this
2227 function can't copy symlinks. Improve quality of error message
2228 when attempting to copy files that are neither regular files nor
2231 2012-12-12 Dmitry Antipov <dmantipov@yandex.ru>
2233 * dispnew.c (set_window_cursor_after_update): Use clip_to_bounds.
2234 * gtkutil.c (xg_set_toolkit_scroll_bar_thumb):
2235 * window.c (Frecenter):
2236 * xdisp.c (resize_mini_window, hscroll_window_tree, draw_glyphs):
2237 * xterm.c (x_set_toolkit_scroll_bar_thumb): Likewise.
2239 2012-12-12 Daniel Colascione <dancol@dancol.org>
2241 * unexcw.c (fixup_executable): Use posix_fallocate to ensure that
2242 the dumped Emacs is not a sparse file, greatly improving Cygwin
2243 "make bootstrap" performance.
2245 2012-12-11 Michael Albinus <michael.albinus@gmx.de>
2247 * inotify.c (inotify_callback): Generate an Emacs event for every
2248 incoming inotify event.
2250 2012-12-11 Eli Zaretskii <eliz@gnu.org>
2252 * xdisp.c (handle_face_prop): Fix logic of computing
2253 it->start_of_box_run_p.
2254 (append_space_for_newline): If the glyph row is R2L, reset the
2255 iterator's end_of_box_run_p flag before prepending the space glyph.
2256 (extend_face_to_end_of_line): If the glyph row is R2L, reset the
2257 iterator's start_of_box_run_p flag before prepending the stretch.
2258 (append_glyph, produce_image_glyph, append_composite_glyph)
2259 (append_stretch_glyph, append_glyphless_glyph): Reverse the
2260 left_box_line_p and right_box_line_p flags of the glyph for R2L
2261 glyph rows. (Bug#13011)
2263 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>
2265 * buffer.c (Fset_buffer_multibyte): Do not force redisplay
2266 if changed buffer is not shown in a window.
2267 * insdel.c (prepare_to_modify_buffer): Likewise.
2268 * window.c (replace_buffer_in_windows_safely): Do nothing
2269 if buffer is not shown in a window.
2270 (Fforce_window_update): Likewise if string or buffer argument
2273 2012-12-11 Eli Zaretskii <eliz@gnu.org>
2275 * inotify.c (Finotify_add_watch): Rename decoded_file_name to
2276 encoded_file_name, which is what it is.
2278 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>
2280 Consistently use marker_position and marker_byte_position.
2281 * fringe.c (Ffringe_bitmaps_at_pos):
2282 * indent.c (Fvertical_motion):
2283 * insdel.c (prepare_to_modify_buffer):
2284 * keyboard.c (make_lispy_position):

2287 (Fset_window_configuration):
2288 * xdisp.c (message_dolog, with_echo_area_buffer_unwind_data)
2289 (mark_window_display_accurate_1, redisplay_window, decode_mode_spec):
2290 Replace direct access to marker fields with calls
2291 to marker_position and/or marker_byte_position.
2293 2012-12-11 Juanma Barranquero <lekktu@gmail.com>
2295 * makefile.w32-in (SIG2STR_H): New macro.
2296 (SYSWAIT_H, $(BLD)/emacs.$(O), $(BLD)/process.$(O))
2297 ($(BLD)/w32notify.$(O)): Update dependencies.
2299 2012-12-10 Daniel Colascione <dancol@dancol.org>
2301 * w32term.c, keyboard.c: Fix build break in cygw32 by omitting
2302 Windows file notification functionality unless WINDOWSNT.
2304 * w32gui.h (hprevinst, lpCmdLine, nCmdShow): Remove unused
2307 * w32fns.c (cache_system_info): Initialize the global hinst
2308 variable here so various initialization calls DTRT.
2310 * unexw32.c (hprevinst, lpCmdLine, nCmdShow): Remove unused variables.
2311 (hinst): Remove unneeded extern declaration.
2312 (_start): Remove initialization of above variables; remove
2313 initialization of hinst, as cache_system_info now does that.
2315 * emacs.c (main): Call cache_system_info early in startup; we
2316 previously weren't calling it in Cygwin builds.
2318 * Makefile.in (ntsource, WINDRES, W32_RES, W#@_RES_LINK):
2319 Teach the autoconf build system how to compile a Windows resource file
2320 and link it to Emacs.

2333 and buffer_local_symbols.
2334 * window.h (buffer_shared): Remove declaration.
2335 (wset_buffer): Convert from inline ...
2336 * window.c (wset_buffer): ... to an ordinary function.
2337 (adjust_window_count): New function.
2338 (make_parent_window): Use it.
2339 * xdisp.c (buffer_shared): Remove.

2453 2012-12-08 Eli Zaretskii <eliz@gnu.org>
2455 * w32.c (unsetenv): Return 0 if the input string is too long.
2457 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
2459 Use putenv+unsetenv instead of modifying environ directly (Bug#13070).
2460 * alloc.c (xputenv): New function.
2461 * dbusbind.c (Fdbus_init_bus):
2463 * xterm.c (x_term_init):

2471 instead, use xputenv+unsetenv to set and restore TZ.
2472 (environbuf): Remove static var. All uses removed.
2473 (Fset_time_zone_rule): Do not save TZ and environ;
2474 no longer needed here.
2475 (set_time_zone_rule_tz1, set_time_zone_rule_tz2) [LOCALTIME_CACHE]:
2476 Move to inside set_time_zone_rule; they don't need file scope any more.
2477 (set_time_zone_rule): Maintain the TZ=value string separately.
2478 (syms_of_editfns): Don't initialize initial_tz;
2479 init_editfns now does it.
2480 * emacs.c (dump_tz) [HAVE_TZSET]: Now const.
2481 * lisp.h (xputenv): New decl.
2483 2012-12-08 Fabrice Popineau <fabrice.popineau@gmail.com>
2485 * w32fns.c (emacs_abort): Don't do arithmetics on void pointers.
2487 2012-12-08 Eli Zaretskii <eliz@gnu.org>

2494 informative (Bug#12992).
2496 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
2498 Simplify get_lim_data.
2499 * vm-limit.c (get_lim_data): Combine RLIMIT_AS and RLIMIT_DATA methods.
2500 Remove USG and vlimit methods; no longer used these days.
2501 Add #error catchall just in case.
2503 Assume POSIX 1003.1-1988 or later for signal.h (Bug#13026).
2504 Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,
2505 SIGTTOU, SIGUSR1, SIGUSR2, as Microsoft platforms lack these.
2506 * process.c [subprocesses]: Include <c-ctype.h>, <sig2str.h>.
2507 (deleted_pid_list, Fdelete_process, create_process)
2508 (record_child_status_change, handle_child_signal, deliver_child_signal)
2509 (init_process_emacs, syms_of_process):
2510 Assume SIGCHLD is defined.

2512 (abbr_to_signal): New static function.
2513 (Fsignal_process): Use it to convert signal names to ints.
2514 * sysdep.c (sys_suspend) [!DOS_NT]: Use kill (0, ...) rather than

2522 * w32proc.c (sys_kill): Support negative pids compatibly with POSIX.
2524 2012-12-07 Paul Eggert <eggert@cs.ucla.edu>
2526 * sysdep.c (get_child_status): Abort on internal error (Bug#13086).
2527 This will cause a production Emacs to dump core instead of
2530 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
2532 * frame.c (make_frame): Do not set window's buffer to t.
2533 * window.c (Fsplit_window_internal): Likewise. Previously it was
2534 used to indicate that the window is being set up. Now we use
2535 set_window_buffer for all new windows, so the condition in ...
2536 (Fset_window_buffer): ... is always true and can be removed.
2538 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
2540 Convenient macro to check whether the buffer is hidden.
2541 * buffer.h (BUFFER_HIDDEN_P): New macro.
2542 * frame.c (make_frame): Use it. Adjust comment.
2543 * buffer.c (candidate_buffer): New function.
2544 (Fother_buffer, other_buffer_safely): Use it.
2546 2012-12-06 Eli Zaretskii <eliz@gnu.org>
2548 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG
2549 if the child process is still running. Instead, exit the wait
2550 loop and return zero. (Bug#13086)
2552 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
2554 * frame.h (x_char_width, x_char_height): Remove prototypes.
2555 * w32term.h (x_char_width, x_char_height): Likewise.
2556 * xfns.c (x_char_width, x_char_height): Remove.
2557 * w32fns.c (x_char_width, x_char_height): Likewise.
2558 * nsfns.c (x_char_width, x_char_height): Likewise.

2568 * callproc.c, process.h (record_kill_process):
2569 New function, containing part of the old call_process_kill.
2570 (call_process_kill): Use it.
2571 This does not change call_process_kill's behavior.
2572 * process.c (Fdelete_process): Use record_kill_process to fix a
2573 race condition that could cause Emacs to lose track of a child.
2575 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
2577 Avoid code duplication between prev_frame and next_frame.
2578 * frame.c (candidate_frame): New function. Add comment.
2579 (prev_frame, next_frame): Use it. Adjust comment.
2581 2012-12-06 Eli Zaretskii <eliz@gnu.org>
2583 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
2584 fails, signal an error instead of continuing with an empty
2586 Encode expanded temp file pattern before passing it to mkstemp or
2589 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
2590 Encode the file name before passing it to dostounix_filename, in
2591 case it will downcase it (under w32-downcase-file-names).
2594 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
2596 Minor call-process cleanups.
2597 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
2598 at the same time as other platforms, to simplify analysis.
2599 No need for fd0_volatile since we have synch_process_fd.
2600 Avoid needless emacs_close; arg is always negative.
2602 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
2604 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
2607 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
2609 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
2610 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
2611 and mouse_face_hidden members to a bitfields.
2612 * frame.h (struct frame): Remove set-but-not-used space_width member.
2613 (FRAME_SPACE_WIDTH): Remove.
2614 * nsterm.m, w32term.c, xterm.c: Adjust users.
2615 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
2616 member. Adjust users. Convert term_initted, delete_in_insert_mode,
2617 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
2618 members to a bitfields.
2620 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
2622 Don't let call-process be a zombie factory (Bug#12980).
2623 Fixing this bug required some cleanup of the signal-handling code.
2624 As a side effect, this change also fixes a longstanding rare race
2625 condition whereby Emacs could mistakenly kill unrelated processes,
2626 and it fixes a bug where a second C-g does not kill a recalcitrant
2627 synchronous process in GNU/Linux and similar platforms.
2628 The patch should also fix the last vestiges of Bug#9488,
2629 a bug which has mostly been fixed on the trunk by other changes.
2630 * callproc.c, process.h (synch_process_alive, synch_process_death)
2631 (synch_process_termsig, sync_process_retcode):
2632 Remove. All uses removed, to simplify analysis and so that
2633 less consing is done inside critical sections.
2634 * callproc.c (call_process_exited): Remove. All uses replaced
2635 with !synch_process_pid.
2636 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
2637 These take the role of what used to be in unwind-protect arg.
2639 (block_child_signal, unblock_child_signal):
2640 New functions, to avoid races that could kill innocent-victim processes.
2641 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
2642 (call_process_kill): Record killed processes as deleted, so that
2643 zombies do not clutter up the system. Do this inside a critical
2644 section, to avoid a race that would allow the clutter.
2645 (call_process_cleanup): Fix code so that the second C-g works again
2646 on common platforms such as GNU/Linux.
2647 (Fcall_process): Create the child process in a critical section,
2648 to fix a race condition. If creating an asynchronous process,
2649 record it as deleted so that zombies do not clutter up the system.
2650 Do unwind-protect for WINDOWSNT too, as that's simpler in the
2651 light of these changes. Omit unnecessary call to emacs_close
2652 before failure, as the unwind-protect code does that.
2653 * callproc.c (call_process_cleanup):
2654 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
2655 * process.c (record_deleted_pid): New function, containing
2656 code refactored out of Fdelete_process.
2657 (Fdelete_process): Use it.
2658 (process_status_retrieved): Remove. All callers changed to use
2659 child_status_change.
2660 (record_child_status_change): Remove, folding its contents into ...
2661 (handle_child_signal): ... this signal handler. Now, this
2662 function is purely a handler for SIGCHLD, and is not called after
2663 a synchronous waitpid returns; the synchronous code is moved to
2664 wait_for_termination. There is no need to worry about reaping
2665 more than one child now.
2666 * sysdep.c (get_child_status, child_status_changed): New functions.
2667 (wait_for_termination): Now takes int * status and bool
2668 interruptible arguments, too. Do not record child status change;
2669 that's now the caller's responsibility. All callers changed.
2670 Reimplement in terms of get_child_status.
2671 (wait_for_termination_1, interruptible_wait_for_termination):
2672 Remove. All callers changed to use wait_for_termination.
2673 * syswait.h: Include <stdbool.h>, for bool.
2674 (record_child_status_change, interruptible_wait_for_termination):
2676 (record_deleted_pid, child_status_changed): New decls.
2677 (wait_for_termination): Adjust to API changes noted above.
2679 * bytecode.c, lisp.h (Qbytecode): Remove.
2680 No longer needed after 2012-11-20 interactive-p changes.
2682 2012-12-03 Eli Zaretskii <eliz@gnu.org>
2684 * xdisp.c (redisplay_window): If the cursor is visible, but inside
2685 the scroll margin, move point outside the margin. (Bug#13055)
2687 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
2689 * gtkutil.c (my_log_handler): New function.
2690 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
2692 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
2694 * lisp.h (modify_region): Rename to...
2695 (modify_region_1): ...new prototype.
2696 * textprop.c (modify_region): Now static. Adjust users.
2697 * insdel.c (modify_region): Rename to...
2698 (modify_region_1): ...new function to work with current buffer.
2699 Adjust comment and users. Use true and false for booleans.
2701 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
2703 * alloc.c (free_save_value): New function.
2704 (safe_alloca_unwind): Use it.
2705 * lisp.h (free_save_value): New prototype.
2706 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
2708 (save_excursion_restore): Adjust to match saved data structure.
2709 Use free_save_value to offload some work from GC. Drop obsolete
2712 2012-12-03 Chong Yidong <cyd@gnu.org>
2714 * fileio.c (Vauto_save_list_file_name): Doc fix.
2716 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
2718 * w32fns.c: Remove prototype of atof.
2719 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
2721 (file_dialog_callback): Make it UINT_PTR.
2723 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
2726 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
2727 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
2730 2012-12-03 Glenn Morris <rgm@gnu.org>
2732 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
2734 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
2736 Fix xpalloc confusion after memory is exhausted.
2737 * alloc.c (xpalloc): Comment fix.
2738 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
2739 and signals an error, do not clear charset_table_size, as
2740 charset_table is still valid.
2741 * doprnt.c (evxprintf): Clear *BUF after freeing it.
2743 Use execve to avoid need to munge environ (Bug#13054).
2744 * callproc.c (Fcall_process):
2745 * process.c (create_process):
2746 Don't save and restore environ; no longer needed.
2747 * callproc.c (child_setup):
2748 Use execve, not execvp, to preserve environ.
2750 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
2752 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
2754 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2756 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
2757 display for sliced images (Bug#10500).
2759 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
2761 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
2763 * doc.c (Fdocumentation): Re-add handling of function-documentation,
2764 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
2766 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
2768 * xdisp.c (window_outdated): Remove eassert since it hits
2769 some suspicious corner cases (see Bug#13007 and Bug#13012).
2770 (mode_line_update_needed): New function.
2771 (redisplay_internal, redisplay_window): Use it.
2772 (ensure_selected_frame): New function.
2773 (redisplay_internal, unwind_redisplay): Use it.
2774 (redisplay_internal): Move comment about buffer_shared...
2775 (buffer_shared_and_changed): ...near to its real use.
2777 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
2779 * callproc.c (Fcall_process): Don't misreport vfork failure.
2781 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
2783 * callproc.c (Fcall_process): Fix vfork portability problems.
2784 Do not assume that fd[0], count, filefd, and save_environ survive
2785 vfork. Fix bug whereby wrong errno value could be reported for
2786 pipe failure. Some minor cleanups, too, as follows. Move buf and
2787 bufsize to the context where they're needed. Change new_argv to
2788 be of type char **, as this is more convenient and avoids casts.
2789 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
2790 Now local constants, not macros.
2792 2012-11-18 Kenichi Handa <handa@gnu.org>
2794 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
2795 for the variable "f".

2799 * font.c (font_unparse_xlfd): Exclude special characters from the
2800 generating XLFD name.

2810 Assume EAGAIN and EINTR are defined.
2812 * fileio.c (Fcopy_file): Assume EISDIR is defined.
2813 * gmalloc.c (ENOMEM, EINVAL): Assume they're defined.
2814 * gnutls.c (emacs_gnutls_write): Assume EAGAIN is defined.
2815 * lread.c (readbyte_from_file): Assume EINTR is defined.
2816 * process.c (wait_reading_process_output, send_process) [subprocesses]:
2817 Assume EIO and EAGAIN are defined.
2818 * unexcoff.c (write_segment): Assume EFAULT is defined.
2820 2012-11-27 Eli Zaretskii <eliz@gnu.org>
2822 * fontset.c (Finternal_char_font): Return nil on non-GUI frames.
2825 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
2826 highlighting on the frame was cleared. Prevents assertion
2827 violations when repeatedly clicking on the "Top" link of the
2828 "bread-crumbs" in Info buffers.
2830 2012-11-25 Paul Eggert <eggert@cs.ucla.edu>
2832 * sysdep.c (sys_subshell): Don't assume pid_t fits in int.
2834 2012-11-24 Ken Brown <kbrown@cornell.edu>
2836 * keyboard.c (HAVE_MOUSE):
2837 * frame.c (HAVE_MOUSE): Remove, and rewrite code as if HAVE_MOUSE
2838 were always defined.
2840 2012-11-24 Eli Zaretskii <eliz@gnu.org>
2842 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
2843 between bpos_covered and bpos_max. This fixes cursor display when
2844 several display strings follow each other.
2846 * .gdbinit (pgx): If the glyph's object is a string, display the
2847 pointer to string data, rather than the value of the string object
2848 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
2850 * indent.c (Fvertical_motion): If the starting position is covered
2851 by a display string, return to one position before that, to avoid
2852 overshooting it inside move_it_to. (Bug#12930)
2854 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
2856 * frame.h (struct frame): Remove display_preempted member
2857 since all users are dead long ago.
2858 * nsterm.h (struct x_output): Use the only dummy member.
2859 * w32menu.c (pending_menu_activation): Remove since not
2861 (set_frame_menubar): Adjust user.
2862 * w32term.h (struct x_output): Drop outdated #if 0 code.
2863 (struct w32_output): Use bitfields for explicit_parent,
2864 asked_for_visible and menubar_active members.
2865 Drop unused pending_menu_activation member.
2866 * xterm.h (struct x_output): Drop outdated #if 0 code.
2867 Use bitfields for explicit_parent, asked_for_visible,
2868 has_been_visible and net_wm_state_hidden_seen members.
2870 2012-11-23 Eli Zaretskii <eliz@gnu.org>
2872 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
2873 of a literal "/". (Bug#12955)
2874 (gl-stamp): Invoke fc.exe directly, not through cmd.
2876 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>
2878 Assume POSIX 1003.1-1988 or later for dirent.h (Bug#12958).
2879 * dired.c: Assume HAVE_DIRENT_H.
2880 (NAMLEN): Remove, replacing with ...
2881 (dirent_namelen): New function. All uses changed. Use the GNU macro
2882 _D_EXACT_NAMELEN if available, as it's faster than strlen.
2883 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
2884 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
2885 * makefile.w32-in (DIR_H): Remove. All uses replaced with
2887 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
2888 * ndir.h: Rename to ../nt/inc/dirent.h.
2889 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
2890 Do not include <dirent.h>; no longer needed.
2891 * w32.c: Include <dirent.h> rather than "ndir.h".
2893 2012-11-23 Chong Yidong <cyd@gnu.org>
2895 * xftfont.c (xftfont_open): Remove duplicate assignment.
2897 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
2899 * alloc.c (Fgarbage_collect): Unblock input after clearing
2900 gc_in_progress to avoid note_mouse_highlight glitch with GC.
2901 * frame.h (FRAME_MOUSE_UPDATE): New macro.
2902 * msdos.c (IT_frame_up_to_date): Use it here...
2903 * w32term.c (w32_frame_up_to_date): ...here...
2904 * xterm.c (XTframe_up_to_date): ...and here...
2905 * nsterm.m (ns_frame_up_to_date): ...but not here.
2906 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
2908 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
2909 Do not check whether GC is in progress.
2911 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
2913 * xdisp.c (window_buffer_changed): New function.
2914 (update_menu_bar, update_tool_bar): Use it to
2915 simplify large 'if' statements.
2916 (redisplay_internal): Generalize commonly used
2917 'tail' and 'frame' local variables.
2919 2012-11-22 Eli Zaretskii <eliz@gnu.org>
2921 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
2922 with Windows system header.
2924 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
2926 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
2927 * alloc.c: Assume unistd.h exists.
2928 * fileio.c (Fexpand_file_name) [DOS_NT]: Use getcwd, not getwd.
2929 * sysdep.c (get_current_dir_name): Assume getcwd exists.
2930 (getwd) [USG]: Remove; no longer needed.
2931 (sys_subshell) [DOS_NT]: Use getcwd, not getwd.
2932 * w32.c (getcwd): Rename from getwd, and switch to getcwd's API.
2933 * w32.h (getcwd): Remove decl.
2935 2012-11-21 Stefan Monnier <monnier@iro.umontreal.ca>
2937 * xdisp.c (fast_set_selected_frame): Rename from update_tool_bar_unwind.
2938 Make it set selected_window as well.
2939 (update_tool_bar): Use it.
2941 2012-11-21 Ken Brown <kbrown@cornell.edu>
2943 * emacs.c (main): Set the G_SLICE environment variable for all
2944 Cygwin builds, not just GTK builds. See
2945 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
2947 2012-11-21 Eli Zaretskii <eliz@gnu.org>
2949 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
2950 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
2951 Define for the MSVC compiler.
2953 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
2955 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
2956 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
2957 dostounix_filename. Prevents crashes down the road, because
2958 dostounix_filename assumes it gets a unibyte string.
2959 Reported by Michel de Ruiter <michel@sentient.nl>, see
2960 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html
2962 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
2964 Conflate Qnil and Qunbound for `symbol-function'.
2965 * alloc.c (Fmake_symbol): Initialize `function' to Qnil.
2966 * lread.c (init_obarray): Set `function' fields to Qnil.
2967 * eval.c (Fcommandp): Ignore Qunbound.
2968 (Fautoload, eval_sub, Fapply, Ffuncall, Fmacroexpand):
2969 * data.c (Ffset, Ffboundp, indirect_function, Findirect_function):
2970 Test NILP rather than Qunbound.
2971 (Ffmakunbound): Set to Qnil.
2972 (Fsymbol_function): Never signal an error.
2973 (Finteractive_form): Ignore Qunbound.
2975 2012-11-20 Paul Eggert <eggert@cs.ucla.edu>
2977 * eval.c (interactive_p): Remove no-longer-used decl.
2979 2012-11-20 Dmitry Antipov <dmantipov@yandex.ru>
2981 * xdisp.c (buffer_shared): Adjust comment.
2982 (buffer_shared_and_changed): New function.
2983 (prepare_menu_bars, redisplay_internal): Use it to
2984 decide whether all windows or frames should be updated.
2985 (window_outdated): New function.
2986 (text_outside_line_unchanged_p, redisplay_window): Use it.
2987 (redisplay_internal): Likewise. Fix indentation.
2989 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
2991 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
2992 (syms_of_eval): Remove corresponding defsubr.
2993 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
2995 2012-11-19 Daniel Colascione <dancol@dancol.org>
2997 * w32fns.c (Fx_file_dialog):
2998 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
2999 cygwin_convert_file_name*.
3001 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
3002 Rename cygwin_convert_path* to cygwin_convert_file_name*.
3004 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
3006 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
3008 2012-11-18 Eli Zaretskii <eliz@gnu.org>
3010 * w32select.c: Include w32common.h before w32term.h, so that
3011 windows.h gets included before w32term.h uses some of its
3012 features, see below.
3014 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
3016 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
3018 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
3020 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
3022 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
3023 (ns_select): Return at once if events are held (Bug#12834).
3025 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
3027 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
3028 Needed following 2012-10-20 change. (Bug#12902)
3030 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
3032 * w32proc.c (waitpid): Remove unused label get_result.
3034 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
3036 * makefile.w32-in (SYSWAIT_H): New macro.
3037 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
3038 ($(BLD)/sysdep.$(O)): Update dependencies.
3040 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
3042 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
3043 * callproc.c (relocate_fd): Assume F_DUPFD.
3044 * emacs.c, term.c (O_RDWR): Remove.
3045 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
3046 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
3047 * nsterm.m: Assume <fcntl.h> exists.
3048 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
3049 (create_pty, Fmake_network_process, server_accept_connection)
3050 (wait_reading_process_output, init_process_emacs):
3052 (wait_reading_process_output): Put in a special case for WINDOWSNT
3053 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
3054 It's not clear this is needed, but it's a more-conservative change.
3055 (create_process): Assume FD_CLOEXEC.
3056 (create_process, create_pty): Assume O_NOCTTY.
3057 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
3058 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
3059 Omit if not DOS_NT, since F_GETFL is not defined there.
3060 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
3061 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
3063 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
3064 lack it, since gnulib guarantees this.
3065 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
3067 2012-11-17 Eli Zaretskii <eliz@gnu.org>
3069 * w32.c (faccessat): Pretend that directories have the execute bit
3070 set. Emacs expects that, e.g., in files.el:cd-absolute.
3072 * w32proc.c (create_child): Don't clip the PID of the child
3073 process to fit into an Emacs integer, as this is no longer a
3075 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
3076 reaping only the process specified by PID argument, if that is
3077 positive. Use PID instead of dead_child to know which process to
3078 reap. Wait for the child to die only if WNOHANG is not in
3080 (sys_select): Don't set dead_child.
3082 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
3083 as it is no longer needed.
3085 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
3087 (record_child_status_change): Remove the setting of
3088 record_at_most_one_child for the !WNOHANG case.
3090 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
3092 Fix problems in ns port found by static checking.
3093 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
3094 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
3095 not to process group.
3096 (ns_select): Use emacs_write, not write, as that's more robust
3097 in the presence of signals.
3098 (fd_handler:): Check for read errors.
3100 2012-11-16 Glenn Morris <rgm@gnu.org>
3102 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
3104 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
3106 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
3108 2012-11-16 Eli Zaretskii <eliz@gnu.org>
3110 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
3111 use the same value of thread handle.
3112 (start_timer_thread): If the timer thread exited (due to error),
3113 clean up by closing the two handles it used. Duplicate the caller
3114 thread's handle here, so it gets duplicated only once, when
3115 launching the timer thread. Set priority of the timer thread, not
3117 (getitimer): Don't duplicate the caller thread's handle here.
3120 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
3122 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
3125 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
3127 Remove no-longer-used pty_max_bytes variable.
3128 * process.c (pty_max_bytes): Remove; unused.
3129 (send_process): Do not set it.
3131 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
3133 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
3134 Update dependencies.
3136 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
3138 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
3139 This follows up on the 2012-09-29 patch that removed indirection
3140 for the 'function' field. Reported by Sergey Vinokurov in
3141 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
3143 2012-11-14 Eli Zaretskii <eliz@gnu.org>
3145 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
3146 different name, as the MS runtime does not have such a function,
3147 and probably never will.) All callers changed. Ignore DIRFD
3148 value if PATH is an absolute file name, to match Posix spec
3149 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
3152 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
3154 * xdisp.c (echo_area_display, redisplay_internal):
3155 Omit redundant check whether frame_garbaged is set.
3157 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
3159 Use faccessat, not access, when checking file permissions (Bug#12632).
3160 This fixes a bug that has been present in Emacs since its creation.
3161 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
3162 which must set some sort of record. (Torek's bug report was against
3163 a predecessor of GNU Emacs, but GNU Emacs happened to have the
3164 same common flaw.) See Torek's Usenet posting
3165 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
3166 Posted: Fri Apr 8 14:18:56 1983.
3167 * Makefile.in (LIB_EACCESS): New macro.
3169 * callproc.c (init_callproc):
3170 * charset.c (init_charset):
3171 * fileio.c (check_existing, check_executable, check_writable)
3173 * lread.c (openp, load_path_check):
3174 * process.c (allocate_pty):
3176 Use effective UID when checking permissions, not real UID.
3177 * callproc.c (init_callproc):
3178 * charset.c (init_charset):
3179 * lread.c (load_path_check, init_lread):
3180 Test whether directories are accessible, not merely whether they exist.
3181 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
3182 * fileio.c (check_existing, check_executable, check_writable)
3184 Use symbolic names instead of integers for the flags, as they're
3186 (check_writable): New arg AMODE. All uses changed.
3187 Set errno on failure.
3188 (Ffile_readable_p): Use faccessat, not stat + open + close.
3189 (Ffile_writable_p): No need to call check_existing + check_writable.
3190 Just call check_writable and then look at errno. This saves a syscall.
3191 dir should never be nil; replace an unnecessary runtime check
3192 with an eassert. When checking the parent directory of a nonexistent
3193 file, check that the directory is searchable as well as writable, as
3194 we can't create files in unsearchable directories.
3195 (file_directory_p): New function, which uses 'stat' on most platforms
3196 but faccessat with D_OK (for efficiency) if WINDOWSNT.
3197 (Ffile_directory_p, Fset_file_times): Use it.
3198 (file_accessible_directory_p): New function, which uses a single
3199 syscall for efficiency.
3200 (Ffile_accessible_directory_p): Use it.
3201 * xrdb.c (file_p): Use file_directory_p.
3202 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
3203 * lread.c (openp): When opening a file, use fstat rather than
3204 stat, as that avoids a permissions race. When not opening a file,
3205 use file_directory_p rather than stat.
3206 (dir_warning): First arg is now a usage string, not a format.
3207 Use errno. All uses changed.
3208 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
3209 that merely introduced a race.
3210 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
3211 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
3212 and similarly for the other O_* flags.
3213 * w32.c (sys_faccessat): Rename from sys_access and switch to
3214 faccessat's API. All uses changed.
3215 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
3216 (magic_db): Rename from magic_file_p.
3217 (magic_db, search_magic_path): Return an XrmDatabase rather than a
3218 char *, so that we don't have to test for file existence
3219 separately from opening the file for reading. This removes a race
3220 fixes a permission-checking problem, and simplifies the code.
3222 (file_p): Remove; no longer needed.
3224 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
3226 Omit glyphs initialization at startup.
3227 * dispnew.c (glyphs_initialized_initially_p): Remove.
3228 (adjust_frame_glyphs_initially): Likewise. Adjust users.
3229 (Fredraw_frame): Move actual code from here...
3230 (redraw_frame): ...to here. Add eassert. Adjust comment.
3231 (Fredraw_display): Use redraw_frame.
3232 * xdisp.c (clear_garbaged_frames): Likewise.
3234 2012-11-13 Eli Zaretskii <eliz@gnu.org>
3236 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
3237 passed to pint2str and pint2hrstr to be at most the size of the
3238 frame's decode_mode_spec_buffer. This avoids crashes with very
3239 large values of FIELD_WIDTH argument to decode_mode_spec.
3242 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
3244 Fix a race with verify-visited-file-modtime (Bug#12863).
3245 Since at least 1991 Emacs has ignored an mtime difference of no
3246 more than one second, but my guess is that this was to work around
3247 file system bugs that were fixed long ago. Since the race is
3248 causing problems now, let's remove that code.
3249 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
3250 whose time stamp is off by no more than a second. Insist that the
3251 file time stamps match exactly.
3253 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
3255 * frame.h (struct frame): Convert external_tool_bar member to
3256 1-bit unsigned bitfield.
3257 * termhooks.h (struct terminal): Remove mouse_moved member since
3258 all users are long dead. Adjust comment on mouse_position_hook.
3260 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
3262 Simplify by using FOR_EACH_FRAME here and there.

3274 (x_window_to_menu_bar): Likewise.
3275 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
3277 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
3279 * data.c (Qdefalias_fset_function): Now static.
3281 Another tweak to vectorlike_header change.

3284 (next_in_free_list, set_next_in_free_list):
3285 New functions, which respect C's aliasing rules better.
3287 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
3289 * window.c (list4i): Rename from 'quad'. All uses changed.
3290 Needed because <sys/types.h> defines 'quad' on Solaris 10.

3304 2012-11-10 Eli Zaretskii <eliz@gnu.org>
3306 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
3307 amount when the scroll margins are too large. When scrolling
3308 backwards in the buffer, give up if cannot reach point or the
3309 scroll margin within a reasonable number of screen lines.
3310 Fixes point position in window under scroll-up/down-aggressively when
3311 point is positioned many lines beyond the window top/bottom.
3314 * ralloc.c (relinquish): If real_morecore fails to return memory
3315 to the system, don't crash; instead, leave the last heap

3337 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
3339 Fix recently introduced crash on MS-Windows (Bug#12839).
3340 * w32term.h (struct scroll_bar): Use convenient header.
3341 (SCROLL_BAR_VEC_SIZE): Remove.
3342 * w32term.c (x_scroll_bar_create): Use VECSIZE.
3344 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
3346 Tweak last vectorlike_header change.
3347 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
3348 vectorlike object on the free list. This is introduced to avoid
3349 some (but not all) pointer casting and aliasing problems, see
3350 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
3351 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike

3355 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
3357 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
3358 been removed, so remove them here also.

3362 * doc.c (Fdocumentation): Handle new property
3363 dynamic-docstring-function to replace the old ad-advice-info.
3365 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>

3369 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3371 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
3372 * fns.c (hashfn_eq, hashfn_eql, sxhash):
3373 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.

3380 * lisp.h (sxhash_combine): New inline function, with the contents
3381 of the old SXHASH_COMBINE.

3383 special hash function containing a comparison that always yields 1.
3385 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3387 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
3388 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
3389 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
3392 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
3394 * image.c (xpm_make_color_table_h): Fix compiler error because
3395 make_hash_table changed.
3397 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
3399 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
3401 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3403 Use ad-hoc comparison function for the profiler's hash-tables.
3404 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
3405 (make_log): Use them.
3406 (handle_profiler_signal): Don't inhibit quit any longer since we don't
3407 call Fequal any more.

3416 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
3417 (hash_lookup, hash_remove_from_table): Move assertion checking of
3418 hashfn result here. Check hash-equality before calling cmpfn.

3420 (hashtest_eq, hashtest_eql, hashtest_equal): New structs.
3421 (syms_of_fns): Initialize them.

3430 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
3431 value of w32-scroll-lock-modifier is neither nil nor one of the
3432 known key modifiers. (Bug#12806)
3434 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
3436 Shrink struct vectorlike_header to the only size field.
3437 * lisp.h (enum pvec_type): Avoid explicit enum member values.
3439 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
3440 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
3441 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
3442 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
3443 information from the vector header. Adjust comment.

3458 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
3459 (large_vectors): Change type to struct large_vector.
3460 (allocate_vector_from_block): Simplify.
3461 (PSEUDOVECTOR_NBYTES): Replace with...
3462 (vector_nbytes): ...new function. Adjust users.
3463 (sweep_vectors): Adjust processing of large vectors.
3464 (allocate_vectorlike): Likewise.
3465 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
3466 Add easserts. Adjust XSETPVECTYPESIZE usage.
3467 (allocate_buffer): Use BUFFER_PVEC_INIT.
3468 (live_vector_p): Adjust to match large vector.
3469 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
3470 * buffer.h (struct buffer): Add next member.
3471 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
3473 (FOR_EACH_BUFFER): Adjust to match struct buffer change.
3474 * fns.c (internal_equal): Adjust to match enum pvec_type change.

3479 (xvecsize): New command.
3481 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
3483 * keyboard.c (event_to_kboard): Do not dereference
3484 frame_or_window field of SELECTION_REQUEST_EVENT
3485 and SELECTION_CLEAR_EVENT events (Bug#12814).
3486 * xterm.h (struct selection_input_event): Adjust comment.
3488 2012-11-07 Eli Zaretskii <eliz@gnu.org>
3490 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
3491 such as Scroll Lock, if the respective keys are treated as
3492 function keys, not as modifiers. This avoids destroying non-ASCII
3493 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
3495 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
3497 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
3499 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
3501 Restore some duplicate definitions (Bug#12814).
3502 This undoes part of the 2012-11-03 changes. Some people build
3503 with plain -g rather than with -g3, and they need the duplicate
3504 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
3505 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
3506 Define as macros, as well as as enums or as constants.
3508 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
3510 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
3511 to keypad keys (Bug#12816).
3513 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
3515 Minor adjustments of recently-changed frame functions.
3516 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
3517 known to be a frame (we're in the FRAMEP branch).
3518 * lisp.h (Qframep): Remove decl. frame.h declares this.
3519 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
3520 since they're meant for Lisp fixnum values.
3522 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3524 * window.c (Fwindow_combination_limit): Revert to the only
3525 required argument and adjust docstring as suggested in
3526 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
3527 by Martin Rudalics <rudalics@gmx.at>.
3529 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3531 Widely used frame validity and checking functions.
3532 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
3533 * frame.c (decode_live_frame, decode_any_frame): New functions.
3534 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
3535 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
3536 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)
3537 (Fframe_pointer_visible_p): Use decode_any_frame.

3540 (Fset_frame_height, Fset_frame_width): Use decode_live_frame.
3541 (Fframe_focus): Likewise. Allow zero number of arguments.
3543 (frame_buffer_list, frame_buffer_predicate): Remove.
3544 * lisp.h (frame_buffer_predicate): Remove prototype.
3545 * buffer.c (Fother_buffer): Use decode_any_frame.
3546 * xdisp.c (Ftool_bar_lines_needed): Likewise.
3547 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
3548 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
3549 (Fclose_font, Ffont_info): Use decode_live_frame.
3550 * fontset.c (check_fontset_name): Likewise.
3551 * terminal.c (Fframe_terminal): Likewise.
3552 * w32fns.c (check_x_frame): Likewise.
3553 * window.c (Fminibuffer_window, Fwindow_at)
3554 (Fcurrent_window_configuration): Likewise.
3555 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
3556 Likewise. Allow zero number of arguments. Adjust docstring.
3557 * dispnew.c (Fredraw_frame): Likewise.
3558 * xfaces.c (frame_or_selected_frame): Remove.
3559 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
3560 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
3561 (Fframe_face_alist): Use decode_live_frame.
3562 * xfns.c (check_x_frame): Likewise.
3564 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3566 * window.c (quad): New function.
3567 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
3568 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
3569 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
3570 (Fwindow_line_height): Use it.
3571 (Fwindow_fringes): Use list3.
3572 (Fwindow_scroll_bars): Use list4.
3573 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
3574 (Fwindow_combination_limit): Allow zero number of arguments.
3576 2012-11-05 Eli Zaretskii <eliz@gnu.org>
3578 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
3580 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
3581 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
3582 file descriptor 2 for standard error. (Bug#12805)
3584 2012-11-05 Chong Yidong <cyd@gnu.org>
3586 * process.c (wait_reading_process_output): Revert previous change.
3588 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
3590 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
3591 This removes code that has been obsolete since around 1990.
3592 * callproc.c (Fcall_process):
3594 * process.c (create_process):
3595 * term.c (dissociate_if_controlling_tty):
3596 Assume setsid exists.
3597 * callproc.c (child_setup): Assume setpgid exists and behaves as
3598 per POSIX.1-1988 or later.
3599 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
3600 * emacs.c (shut_down_emacs):
3601 * sysdep.c (sys_suspend, init_foreground_group):
3602 Assume getpgrp behaves as per POSIX.1-1998 or later.
3603 * msdos.c (setpgrp): Remove.
3604 (tcgetpgrp, setpgid, setsid): New functions.
3605 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
3606 * term.c (no_controlling_tty): Remove; unused.
3607 * w32proc.c (setpgrp): Remove.
3608 (setsid, tcgetpgrp): New functions.
3610 Simplify by assuming __fpending.
3611 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
3612 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
3613 Do not assume that __fpending's result fits in int.
3615 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
3617 Remove EMACS_OUTQSIZE+sleep hack.
3618 * dispnew.c (update_frame_1): Remove hack for terminals slower
3619 than 2400 bps, which throttled Emacs by having it sleep.
3620 This code hasn't worked since at least 2007, when the multi-tty stuff
3621 was added, and anyway those old terminals are long dead.
3622 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
3623 without the dispnew.c change, as dispnew.c doesn't include systty.h.
3625 Fix data-loss with --version (Bug#9574).
3626 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
3627 as we can't assume that emacs_strerror is initialized, and strerror
3628 is good enough here.
3629 (main): Invoke atexit earlier, to catch earlier instances of
3630 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
3632 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
3634 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
3635 (keyDown): Remap keypad keys to X11 virtual key codes.
3637 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
3639 Fix data-loss with --batch (Bug#9574).
3640 * emacs.c: Include <close-stream.h>.
3641 (close_output_streams): New function.
3642 (main): Pass it to atexit, so that Emacs closes stdout and stderr
3643 and handles errors appropriately.
3644 (Fkill_emacs): Don't worry about flushing, as close_output_stream
3647 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
3648 The symptom is a diagnostic "GLib-WARNING **: In call to
3649 g_spawn_sync(), exit status of a child process was requested but
3650 SIGCHLD action was set to SIG_IGN and ECHILD was received by
3651 waitpid(), so exit status can't be returned." The diagnostic
3652 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
3653 The real bug is a race condition between Emacs and glib: Emacs
3654 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
3655 so that glib can't find it. Work around the bug by invoking
3656 waitpid only on subprocesses that Emacs itself creates.
3657 * process.c (create_process, record_child_status_change):
3658 Don't use special value -1 in pid field, as the caller now must
3659 know the pid rather than having the callee infer it.
3660 The inference was sometimes incorrect anyway, due to another race.
3661 (create_process): Set new 'alive' member if child is created.
3662 (process_status_retrieved): New function.
3663 (record_child_status_change): Use it.
3664 Accept negative 1st argument, which means to wait for the
3665 processes that Emacs already knows about. Move special-case code
3666 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
3667 processes that have already been waited for, by testing and
3668 clearing new 'alive' member.
3669 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
3670 now does this internally.
3671 (handle_child_signal): Let record_child_status_change do all
3672 the work, since we do not want to reap all exited child processes,
3673 only the child processes that Emacs itself created.
3674 * process.h (Lisp_Process): New boolean member 'alive'.
3676 Omit duplicate definitions no longer needed with gcc -g3.
3677 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
3678 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
3679 Define only as macros. There's no longer any need to also define
3680 these symbols as enums or as constants, since we now assume
3681 gcc -g3 when debugging.
3683 2012-11-03 Eli Zaretskii <eliz@gnu.org>
3685 * lisp.mk: Adjust comments to the fact that term/internal is now
3686 loaded from loadup.el.
3688 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.

3765 Remove pad from struct input_event.
3766 * termhooks.h (struct input_event): Remove padding field.
3768 * keyboard.c (event_to_kboard): Simplify because frame_or_window
3769 member is never cons for a long time. Adjust comment.
3770 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
3771 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
3772 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
3773 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
3775 2012-11-01 Eli Zaretskii <eliz@gnu.org>

3781 Fix crash when using Emacs as commit editor for git (Bug#12697).
3782 * callproc.c (setpgrp): Remove macro, as we now use setpgid
3783 and it is configured in conf_post.h.
3784 (Fcall_process): Don't invoke both setsid and setpgid; the former
3785 is enough, if it exists.
3786 * callproc.c (Fcall_process, child_setup):
3787 * process.c (create_process): Use setpgid.
3788 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes

3804 2012-10-31 Martin Rudalics <rudalics@gmx.at>
3806 * minibuf.c (read_minibuf): Restore current buffer since
3807 choose_minibuf_frame calling Fset_frame_selected_window may

3821 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
3822 In preparation for fixing bug#12739, move these functions from
3825 * coding.h, coding.c: ... to here, and compile them only when
3826 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
3827 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
3829 2012-10-28 Eli Zaretskii <eliz@gnu.org>
3831 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.

3846 remove last_appdefined_event (Bug#12698).
3848 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
3850 * frame.c (x_set_font): Catch internal error.
3852 2012-10-27 Eli Zaretskii <eliz@gnu.org>
3854 Avoid overflow in w32 implementation of interval timers.
3855 When possible, for ITIMER_PROF count only times the main thread
3857 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
3858 'volatile ULONGLONG' types. All the other data which was
3859 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
3860 (GetThreadTimes_Proc): New typedef.
3861 (w32_get_timer_time): New function, returns a suitable time value
3863 (timer_loop): Enter critical section when accessing ULONGLONG
3864 values of the itimer_data struct, as these accesses are no longer
3865 atomic. Call 'w32_get_timer_time' instead of 'clock'.
3866 Remove unused variable.
3867 (init_timers): Initialize s_pfn_Get_Thread_Times.
3868 (start_timer_thread): Don't assign itimer->caller_thread here.

3875 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
3876 mouse movement events if the menu bar is active. This avoids
3877 producing a busy "hour-glass" cursor by Windows if the mouse
3878 pointer is positioned over a tooltip shown for some menu item.
3880 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
3882 Don't assume process IDs fit in int.
3883 * emacs.c (shut_down_emacs) [!DOS_NT]:
3884 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
3885 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
3886 Use pid_t, not int, to store process IDs, as 'int'
3887 is not wide enough on a few platforms (e.g., AIX and IRIX).
3889 2012-10-23 Kenichi Handa <handa@gnu.org>
3891 The following change is to make face-font-rescale-alist work

3917 * frame.c (Fmouse_position, Fmouse_pixel_position):
3918 * xdisp.c (produce_stretch_glyph):
3919 Declare local vars only when they're needed.

3922 This is safer, and avoids OpenBSD warnings about unused vars.
3923 * keyboard.c (record_menu_key): Remove unnecessary decl.
3924 (poll_timer): Define only if POLL_FOR_INPUT is defined.
3925 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
3926 as our definition clashes with OpenBSD's.
3927 * xfaces.c (load_face_colors, check_lface_attrs)
3928 (get_lface_attributes_no_remap, get_lface_attributes)
3929 (lface_fully_specified_p, x_supports_face_attributes_p)
3930 (tty_supports_face_attributes_p, face_fontset, realize_face)
3931 (realize_x_face, realize_tty_face):
3932 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
3933 merely Lisp_Object *. This is more informative and avoids
3934 a warning on OpenBSD about accessing beyond an object's size.
3936 2012-10-20 Chong Yidong <cyd@gnu.org>
3938 * lread.c (Fload): Doc fix (Bug#12592).

3964 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
3965 (staticpro): If we run out of staticpro slots, die with an
3966 informative error instead of just calling emacs_abort.

4183 * w32select.c (waiting_for_input): Declare by including "keyboard.h"
4184 instead of having a wrong decl.
4185 * nsmenu.m (waiting_for_input): Remove wrong decl.
4187 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
4189 keyboard.c, keymap.c: Use bool for booleans.
4190 * dispnew.c (sit_for): Distinguish between 3-way display_option
4191 and boolean do_display.
4192 * keyboard.c (single_kboard, this_command_key_count_reset)
4193 (waiting_for_input, echoing, immediate_quit, input_pending)

4221 * keyboard.c (timers_run, swallow_events)
4222 (detect_input_pending_run_timers):
4223 * process.c (wait_reading_process_output):
4224 Use unsigned for counter where wraparound-on-overflow is desired,
4225 since unsigned is guaranteed to have that behavior and signed is not.
4226 (read_char): Use ptrdiff_t for string length.
4227 (get_input_pending): Remove first argument, since it was always
4228 the same pointer-to-int (now pointer-to-boolean) &input_pending,
4229 and behave as if it had that value. Return new value of
4230 input_pending. All callers changed.
4231 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
4232 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's
4234 * keymap.c (push_key_description): Omit last arg, which was always 1.
4235 All callers changed.
4237 * regex.c (immediate_quit) [emacs]: Remove duplicate decl.
4239 2012-10-10 Juanma Barranquero <lekktu@gmail.com>

4253 * termopts.h (flow_control, meta_key): Remove unused decls.
4254 * dispnew.c, indent.c, nsterm.m, term.c, xsettings.c, xsmfns.c:
4255 Don't include termopts.h.
4257 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>
4259 * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers.
4261 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
4263 * commands.h (immediate_quit): Remove duplicate decl.
4265 2012-10-09 Jan Djärv <jan.h.d@swipnet.se>
4267 * nsfont.m (Vfonts_in_cache): Remove, not needed as font.c handles
4269 (nsfont_open): Remove setting of Vfonts_in_cache.
4270 (syms_of_nsfont): Remove initialization of Vfonts_in_cache.
4272 2012-10-09 Eli Zaretskii <eliz@gnu.org>
4274 * w32fns.c (w32_last_error): Change the return value to DWORD, to
4275 match what GetLastError returns. Explain why the function is
4278 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
4279 'is_tooltip_frame', to avoid confusion with its global namesake.
4281 2012-10-08 Daniel Colascione <dancol@dancol.org>
4283 * xdisp.c (start_hourglass): Call w32_note_current_window when
4284 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
4285 build that caused Emacs to display the hourglass cursor forever.
4287 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
4288 which is broken under remote desktop, calculate the number of
4289 colors available for a display based on the display's number of
4290 planes and number of bits per pixel per plane. (bug#10397).
4292 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
4294 * nsfont.m (Vfonts_in_cache): New variable.
4295 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
4296 are used. Add cached fonts to Vfonts_in_cache.
4297 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
4299 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
4301 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
4303 (FONT_H): Define after FRAME_H.
4304 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
4305 Update dependencies.
4307 * w32term.c: Remove leftover declaration of keyboard_codepage.
4309 2012-10-08 Eli Zaretskii <eliz@gnu.org>
4311 * makefile.w32-in (FONT_H): Add $(FRAME_H).
4312 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
4313 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
4314 (GLOBAL_SOURCES): Add cygw32.c.
4315 ($(BLD)/unexw32.$(O)):
4317 ($(BLD)/w32console.$(O)):
4318 ($(BLD)/w32fns.$(O)):
4319 ($(BLD)/w32heap.$(O)):
4320 ($(BLD)/w32menu.$(O)):
4321 ($(BLD)/w32proc.$(O)): Add w32common.h.
4323 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
4325 (x_to_w32_color): Don't modify the argument, modify a copy instead.
4327 2012-10-08 Daniel Colascione <dancol@dancol.org>
4329 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
4330 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
4331 accidental message numbering hole. Change other messages to
4334 * w32select.h (HAVE_W32SELECT): Remove.
4336 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
4337 w32common.h instead of w32heap.h.
4339 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
4340 (get_allocation_unit, get_processor_type, get_w32_major_version)
4341 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
4342 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
4343 (OS_NT, os_subtype, cache_system_info): Move declarations to
4346 * w32heap.c: Include w32common.h.
4347 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
4348 (w32_minor_version, w32_build_number, w32_subtype):
4349 Remove duplicate definitions.
4351 * w32fns.c: Include w32common.h; include w32heap.h only in
4354 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
4355 Use `report_file_error' instead of `error' in order to better
4356 inform users of what went wrong. Increase NTGUI_UNICODE file
4357 dialog box file name length to 32k, the maximum allowed by the NT
4360 * w32common.h: New file.
4361 (ROUND_UP, ROUND_DOWN, get_page_size)
4362 (get_allocation_unit, get_processor_type, get_w32_major_version)
4363 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
4364 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
4365 (OS_NT, os_subtype, cache_system_info): Move here.
4367 * unexw32.c, unexcw.c: Include w32common.h.
4369 * emacs.c (main): Use (defined (WINDOWSNT) || defined
4370 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
4371 to call syms_of_w32select.
4373 * cygw32.h: Remove obsolete EXFUN declarations.
4375 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
4377 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
4378 of w32inevt.o from SOME_MACHINE_OBJECTS.
4380 2012-10-08 Daniel Colascione <dancol@dancol.org>
4382 * image.c: Permanent fix for JPEG compilation issue --- limit
4383 jpeglib `boolean' redefinition to Cygwin builds.
4385 2012-10-08 Eli Zaretskii <eliz@gnu.org>
4387 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
4389 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
4392 2012-10-08 Daniel Colascione <dancol@dancol.org>
4394 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
4395 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
4396 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
4397 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
4398 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
4399 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
4400 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
4401 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
4402 now a supported configuration.
4404 * Makefile.in: consolidate image variables into LIBIMAGE; add
4405 W32_OBJ and W32_LIBS. Compile new files.
4408 (_DebPrint) declare tracing facility for W32 debugging. We need
4409 to unify tracing later.
4411 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
4412 unconditional use of W32 Unicode functions. Cygwin runs only on
4413 100% Unicode operating systems.
4415 * cygw32.c: New file. Define Cygwin-specific facilities.
4416 (Fcygwin_convert_path_to_windows)
4417 (Fcygwin_convert_path_from_windows): New user functions for
4418 accessing Cygwin path-munging routines.
4420 * cygw32.h: New file.
4421 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
4422 UTF-16LE strings temporarily inside non-Lisp-visible string
4425 (w32_strerror): Just what it says on the tin.
4427 * emacs.c: Make the NS fork-then-exec code for daemon-launching
4428 also run for Cygwin; both systems have the same problem with using
4429 GUI facilities in a forked child. Also call syms_of_cygw32,
4430 syms_of_w32select in correct places.
4432 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
4433 needs fork-then-exec for daemon launching.
4435 * font.h: Include frame.h.
4437 * image.c: Use the image library cache machinery only when we're
4438 compiling for native WINDOWSNT; Cygwin can use shared libraries
4439 like any other Unixlike system.
4441 * keyboard.c: Clarify a comment regarding the input loop.
4443 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
4444 functions directly instead of trying to detect at runtime that our
4445 host operating system supports them. We make this change for two
4446 reasons: Cygwin lacks support for the multibyte character
4447 conversion functions used by the legacy menu code, and Cygwin
4448 never needs to rely on non-Unicode APIs.
4450 * unexw32.c (hinst): Declare extern.
4452 * w32.c: Change header order;
4453 (w32_strerror): Move to w32fns.c because we need it for
4454 non-WINDOWSNT builds.
4456 * w32.h: Add #error macro to make sure we don't include w32.h for
4457 Cygwin builds. Remove w32select declarations.
4459 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
4460 w32fns.c. w32console.c is WINDOWSNT-only.
4462 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
4463 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
4465 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
4466 (w32_major_version, w32_minor_version, w32_build_number)
4467 (os_subtype, sound_type): Define here
4468 (w32_defined_color): Make color parameter const for consistency
4469 with other _defined_color functions.
4470 (w32_createwindow): Unconditionally call w32_init_class instead of
4471 doing so only when hprevinst is non-NULL. Plumbing hprevinst
4472 through the code is complex and unnecessary because class
4473 registration is practically free.
4474 (w32_name_of_message): New EMACSDEBUG-only function.
4475 (Fset_message_beep): Move here
4476 (Fx_open_connection): Require that the display name for Windows be
4477 "w32" for consistency, emacsclient disambiguation, and maybe, one
4478 day, multi-window-system support.
4479 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
4480 Cygwin files for W32 GUI facilities, since these clearly don't
4481 expect Cygwin names.
4482 (_DebPrint): Define.
4483 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
4484 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
4485 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
4486 (w32_last_error): Remove.
4488 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
4490 * w32heap.c (syspage_mask): Declare here.
4491 (cache_system_info): Remove.
4493 * w32inevt.c (faked_key): Define globally, not statically.
4494 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
4495 (w32_console_toggle_lock_key): Move to w32fns.c.
4497 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
4499 * w32proc.c (_DebPrint): Move to w32fns.c.
4500 * w32select.c: Include string.h, stdio.h for Cygwin.
4501 * w32select.h: New File.
4503 * w32term.c: Include io.h for non-CYGWIN builds; needed for
4505 (w32_message_fd): New variable. Under Cygwin, holds the file
4506 descriptor the system used to tell us about pending thread
4509 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
4510 that prevented compilation under non-WINDOWSNT systems.
4512 (w32_initialize): Open /dev/windows and assign it to
4513 w32_message_fd. Provide w32 feature.
4515 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
4516 (WM_EMACS_INPUT_READY): add.
4517 (prepend_msg, w32_message_fd): Declare globally.
4520 (keyboard_handle): Use only when WINDOWSNT.
4521 (notify_msg_ready): New function. Posts a message to the main
4522 thread's message queue under CYGWIN, which wakes up the main
4523 thread from select(2) by making the /dev/windows file descriptor
4524 ready. Under WINDOWSNT, it sets an event the same way the old
4527 (post, prepend_msg): Actually call notify_msg_ready instead of
4528 setting the input event directly.
4530 2012-10-07 Eli Zaretskii <eliz@gnu.org>
4532 * ralloc.c (relinquish): If a heap is ready to be relinquished,
4533 but it still has blocs in it, don't return it to the system,
4534 instead of aborting. (Bug#12402)
4536 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
4538 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
4540 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
4541 MAC_OS_X_VERSION_10_6.
4542 (syms_of_nsterm): Remove comment about Panther and above for
4544 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
4545 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
4546 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
4548 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
4549 MAC_OS_X_VERSION_10_4.
4551 * nsmenu.m (fillWithWidgetValue:): Remove code for <
4552 MAC_OS_X_VERSION_10_2.
4554 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
4556 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
4557 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
4559 * nsterm.m (ns_in_resize): Remove (Bug#12479).
4560 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
4561 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
4562 Remove ns_in_resize check.
4563 (ns_clear_frame_area): Remove resize handle code.
4565 * nsfns.m (ns_in_resize): Remove.
4566 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
4567 Remove ns_in_resize check.
4569 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
4571 Improve sys_siglist detection.
4572 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
4573 defined as a macro, as is done in Solaris.
4574 (sys_siglist_entries): New macro.
4575 (save_strsignal): Use it.
4576 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
4577 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
4579 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
4581 * nsfns.m (Fx_create_frame): Call x_default_parameter with
4582 fullscreen/Fullscreen.
4584 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
4585 tobar_height is new.
4587 * nsterm.m (x_make_frame_visible): Check for fullscreen.
4588 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
4589 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
4590 (windowDidResize:): Check for correct window if old style fullscreen.
4591 Capitalize word in comment. Remove incorrect comment.
4592 (initFrameFromEmacs:): tbar_height renamed tibar_height.
4593 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
4594 error in drawing background.
4595 (toggleFullScreen:): Remove comment. Rearrange calls.
4596 Set toolbar values to zero, save old height in tobar_height.
4597 Restore tool bar height when leaving fullscreen.
4598 (canBecomeMainWindow): New function.
4600 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
4602 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
4604 2012-10-05 Eli Zaretskii <eliz@gnu.org>
4606 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
4608 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
4609 that time stamps of directories could also be changed.
4610 Don't request the too broad GENERIC_WRITE, only the more restrictive
4611 FILE_WRITE_ATTRIBUTES access rights.
4613 * fileio.c (Fset_file_times): Special-case ignoring errors for
4614 directories only on MSDOS, not on MS-Windows.
4616 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
4618 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
4620 2012-10-04 Eli Zaretskii <eliz@gnu.org>
4622 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
4623 see whether CreateFile failed.
4625 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
4627 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
4628 to avoid similar races.
4629 * keyboard.c (pending_signals): Now bool, not int.
4631 Port timers to OpenBSD, plus check for timer failures.
4632 OpenBSD problem reported by Han Boetes.
4633 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
4635 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
4636 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
4637 like OpenBSD, which has timer_settime but does not declare it.
4638 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
4639 whether to use itimerspec-related primitives. All uses of
4640 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
4642 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
4644 * profiler.c (handle_profiler_signal): Fix a malloc race
4645 that caused Emacs to hang on Fedora 17 when profiling Lisp.
4647 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
4649 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
4651 2012-10-02 Eli Zaretskii <eliz@gnu.org>
4653 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
4654 consistent with the change in return value of 'safe_strsignal'.
4656 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
4658 Prefer plain 'static' to 'static inline' (Bug#12541).
4659 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
4660 (bidi_set_sor_type, bidi_push_embedding_level)
4661 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)

4666 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
4667 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
4668 Now 'static', not 'static inline'.
4670 Count overruns when profiling; change units to ns.
4671 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
4672 Give extra weight to samples after overruns, to attempt to count
4673 the time more accurately.
4674 (setup_cpu_timer): Change sampling interval units from ms to ns, since
4675 the underlying primitives nominally do ns.
4676 (Fprofiler_cpu_start): Document the change. Mention that
4677 the sampling intervals are only approximate.
4679 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
4681 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.

4684 case for the special 0 coding-system.
4686 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
4687 (Fmake_overlay): Remove redundant tests.
4688 (fix_start_end_in_overlays): Remove redundant recentering.

4693 Update dependencies.
4695 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
4697 Fix a malloc race condition involving strsignal.
4698 A signal can arrive in the middle of a malloc, and Emacs's signal
4699 handler can invoke strsignal, which can invoke malloc, which is
4700 not portable. This race condition bug makes Emacs hang on GNU/Linux.
4701 Fix it by altering the signal handler so that it does not invoke
4703 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
4704 * process.c (status_message): Use const pointer, in case strsignal
4705 is #defined to safe_strsignal.
4706 * sysdep.c (sys_siglist, init_signals): Always define and
4707 initialize a substitute sys_siglist if the system does not define
4708 one, even if HAVE_STRSIGNAL.
4709 (safe_strsignal): Rename from strsignal. Always define,
4710 using sys_siglist. Return a const pointer.
4711 * syssignal.h (safe_strsignal): New decl.
4712 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
4714 2012-10-01 Eli Zaretskii <eliz@gnu.org>
4716 * w32proc.c (timer_loop): Fix code that waits for timer
4717 expiration, to avoid high CPU usage.
4719 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
4721 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
4722 (sweep_weak_table): Remove redundant prototypes.
4724 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
4726 * emacs.c: Move the inclusion of TERM_HEADER after including
4727 windows.h on WINDOWSNT. This avoids compilation problems with
4730 2012-10-01 Eli Zaretskii <eliz@gnu.org>
4732 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
4733 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
4734 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
4735 as the previous version used 'void *'.
4737 * ralloc.c (ROUNDUP): Fix last change.
4738 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
4741 * w32proc.c <disable_itimers>: New static flag.
4742 (init_timers): Initialize it to zero, after creating the critical
4743 sections used by the timer threads.
4744 (term_timers): Set to 1 before deleting the critical sections.
4745 (getitimer, setitimer): If disable_itimers is non-zero, return an
4746 error indication without doing anything. Reported by Fabrice
4747 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
4748 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
4750 [!HAVE_SETITIMER]: Behave as the previous version that didn't
4753 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
4754 term_ntproc after all the other bookkeeping, to get timers working
4755 as long as possible.
4757 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
4759 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
4760 Suggested by Juri Linkov in
4761 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
4763 Prefer plain 'static' to 'static inline' (Bug#12541).
4764 With static functions, modern compilers inline pretty well by
4765 themselves; advice from programmers often hurts as much as it helps.
4766 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
4767 this change shrinks the text size of the Emacs executable by 1.1%
4768 without affecting CPU significantly in my benchmark.
4769 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)

4849 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
4851 Revert the FOLLOW-SYMLINKS change for file-attributes.
4852 Doing it right would require several changes to Tramp, and there's
4853 not enough time to get that tested before the freeze today.
4854 * dired.c (directory_files_internal, Ffile_attributes):
4857 * frame.c (x_report_frame_params): Port better to wider ints.
4858 Do not assume that EMACS_UINT is the same width as uprintmax_t,
4859 or that pointers can be printed in 15 decimal digits.
4860 Avoid GCC warnings if EMACS_UINT is wider than a pointer.

4891 * w32.c (init_environment, get_emacs_configuration): Support AMD64
4893 (init_ntproc): Cast arguments of _open_osfhandle to intptr_t, for
4894 compatibility with x64.
4896 * vm-limit.c (lim_data): Now size_t.
4897 (check_memory_limits): Adjust prototypes of real_morecore and
4898 __morecore to receive argument of type ptrdiff_t. Use size_t for

4984 2012-09-30 Kenichi Handa <handa@gnu.org>
4986 * coding.c (decode_coding_ccl, encode_coding_ccl): Pay attention
4987 to the buffer relocation which may be caused by ccl_driver.

5041 Suggested by Eli Zaretskii in
5042 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00811.html>.
5044 2012-09-30 Eli Zaretskii <eliz@gnu.org>
5046 * profiler.c (Fprofiler_cpu_stop): Use timer_settime only if
5047 HAVE_TIMER_SETTIME is defined.
5049 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
5051 Profiler improvements: more-accurate timers, overflow checks.
5052 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
5053 signal.h, setjmp.h. Include systime.h instead.
5054 (saturated_add): New function.

5061 All uses changed to store the new value.
5062 (handle_profiler_signal): Rename from sigprof_handler_1,
5063 for consistency with other handlers. Do not check whether
5064 cpu_log is a hash-table if garbage collecting, since it
5065 doesn't matter in that case.

5067 for consistency with other handlers.
5068 (setup_cpu_timer): New function, with much of what used to be in
5069 Fprofiler_cpu_start. Check for out-of-range argument.
5070 Prefer timer_settime if available, and prefer
5071 thread cputime clocks, then process cputime clocks, then
5072 monotonic clocks, to the old realtime clock. Use make_timeval
5073 to round more-correctly when falling back to setitimer.
5074 (Fprofiler_cpu_start): Use it.
5075 (Fprofiler_cpu_stop): Prefer timer_settime if available.
5076 Don't assume that passing NULL as the 2nd argument of setitimer
5077 is the same as passing a pointer to all-zero storage.
5078 Ignore SIGPROF afterwards.
5079 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
5080 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
5081 non-fatal signal handlers. Ignore SIGPROF on startup.
5082 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
5083 in profiler.c, since sysdep.c now uses it.
5085 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.
5086 Suggested by Eli Zaretskii in
5087 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.

5098 * alloc.c (Fgarbage_collect):
5099 * eval.c (interactive_p, Fsignal, eval_sub, Ffuncall, Fbacktrace)
5100 (Fbacktrace_frame): Adjust accordingly.
5102 2012-09-28 Glenn Morris <rgm@gnu.org>
5104 * eval.c (Frun_hook_with_args, Frun_hook_with_args_until_success)
5105 (Frun_hook_with_args_until_failure): Doc fixes.
5107 2012-09-28 Eli Zaretskii <eliz@gnu.org>
5109 * xdisp.c (syms_of_xdisp) <Qredisplay_internal>: Rename from

5140 * charset.c, charset.h (maybe_unify_char): Now static.
5141 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
5142 Since this stuff is now private to charset.c, there's no need for
5143 a public macro and no need to inline by hand.

5172 2012-09-25 Juanma Barranquero <lekktu@gmail.com>
5174 * makefile.w32-in ($(BLD)/callproc.$(O)): Update dependencies.
5176 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>
5178 Prefer POSIX timers if available.
5179 They avoid a race if the timer is too close to the current time.
5180 * atimer.c (alarm_timer, alarm_timer_ok) [SIGEV_SIGNAL]: New static vars.
5181 (set_alarm) [SIGEV_SIGNAL]: Use POSIX timers if available.

5198 * image.c (reset_image_types): New function.
5200 * emacs.c [WINDOWSNT] (Vlibrary_cache): Move from w32.c.

5207 * w32.h (Vlibrary_cache): Do not declare.
5209 2012-09-25 Eli Zaretskii <eliz@gnu.org>
5211 * w32proc.c (sys_signal): Handle all signals defined by the
5212 MS-Windows runtime, not just SIGCHLD. Actually install the signal
5213 handlers for signals supported by Windows. Don't override
5214 term_ntproc as the handler for SIGABRT.
5215 (sigaction): Rewrite to call sys_signal instead of duplicating its
5217 (sys_kill): Improve commentary.
5219 * w32.c (term_ntproc): Accept (and ignore) one argument, for
5220 consistency with a signature of a signal handler. All callers
5222 (init_ntproc): Accept an argument DUMPING. If dumping, don't
5223 install term_ntproc as a signal handler for SIGABRT, as that
5224 should be done by the dumped Emacs.
5226 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
5228 * w32select.c (term_w32select): Protect against repeated
5229 invocation by setting clipboard_owner to NULL after calling
5232 * emacs.c (shut_down_emacs, main): Adapt the calls to init_ntproc
5233 and term_ntproc to their modified signatures.
5235 * character.c (char_string, string_char): Remove calls to
5236 MAYBE_UNIFY_CHAR. See the discussion starting at

5240 2012-09-25 Chong Yidong <cyd@gnu.org>
5242 * xdisp.c (mode_line_inverse_video): Delete obsolete variable.
5244 2012-09-24 Stefan Monnier <monnier@iro.umontreal.ca>
5246 * bytecode.c (exec_byte_code): Signal an error instead of aborting,
5247 when encountering an unknown bytecode.
5249 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
5251 image.c, indent.c: Use bool for booleans.
5252 * dispextern.h (struct image_type): Members valid_p, load, init
5253 now return bool, not int. All uses changed.
5254 * image.c: Omit unnecessary static decls.
5255 (x_create_bitmap_mask, x_build_heuristic_mask):
5256 Return void, not int, since callers don't care about the return value.

5291 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5293 Move pid_t related decls out of lisp.h.
5294 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
5295 (interruptible_wait_for_termination):
5296 Move these decls from lisp.h to syswait.h, since they use pid_t.
5297 Needed on FreeBSD; see Herbert J. Skuhra in
5298 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
5299 * callproc.c: Include syswait.h.

5319 Use bool for boolean.
5320 * gtkutil.c (xg_update_frame_menubar):

5345 2012-09-23 Eli Zaretskii <eliz@gnu.org>
5347 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
5348 fatal_error_backtrace.
5350 * w32proc.c (sys_kill): Undo last change: don't do anything when
5351 invoked to deliver SIGABRT to our own process. This is now
5352 handled by emacs_raise.
5354 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
5356 * w32term.c (w32_read_socket): Remove leftover reference to
5357 interrupt_input_pending.
5359 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5361 Do not use SA_NODEFER.
5362 Problem reported by Dani Moncayo in
5363 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
5365 * sysdep.c (emacs_abort): Do not reset signal handler.
5366 * emacs.c (terminate_due_to_signal): Reset signal handler here.
5367 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
5368 wanted even on POSIXish hosts, and it doesn't work on Windows.
5370 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
5372 * xterm.c (x_term_init): Call fixup_locale before and after calling
5373 gtk_init (Bug#12392).
5375 2012-09-23 Chong Yidong <cyd@gnu.org>
5377 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
5378 Vdynamic_library_alist.
5380 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
5381 (Fgnutls_available_p): Caller changed.
5383 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
5384 (Flibxml_parse_xml_region): Likewise.
5386 * dispextern.h (struct image_type): Remove arg from init function.
5388 * image.c (Finit_image_library, lookup_image_type)
5389 (define_image_type): Remove now-unneeded second arg.
5390 (init_xpm_functions, init_png_functions, init_jpeg_functions)
5391 (init_tiff_functions, init_gif_functions, init_svg_functions):
5392 Arglist and w32_delayed_load calling convention changed.
5393 (gs_type): Remove init_gs_functions; there is no such function.
5394 (valid_image_p, make_image): Fix caller to lookup_image_type.
5396 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5398 Simplify and avoid signal-handling races (Bug#12471).
5400 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
5401 Avoid recursive loop if there's a fatal error in the function itself.
5402 * atimer.c (pending_atimers):
5403 * blockinput.h: Don't include "atimer.h"; no longer needed.
5404 (interrupt_input_pending): Remove. All uses removed.
5405 pending_signals now counts both atimers and ordinary interrupts.
5406 This is less racy than having three separate pending-signal flags.
5407 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
5409 Rename from their upper-case counterparts BLOCK_INPUT,
5410 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
5411 INPUT_BLOCKED_P, and turn into functions. All uses changed.
5412 This makes it easier to access volatile variables more accurately.
5413 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
5414 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
5415 that's more reliable if the code is buggy and sets
5416 interrupt_input_blocked to a negative value. All uses changed.
5417 * atimer.c (deliver_alarm_signal):
5418 Remove. No need to deliver this to the parent; any thread can
5419 handle this signal now. All uses replaced by underlying handler.
5420 * atimer.c (turn_on_atimers):
5421 * dispnew.c (handle_window_change_signal):
5422 * emacs.c (handle_danger_signal):
5423 * keyboard.c (kbd_buffer_get_event):
5424 Don't reestablish signal handler; not needed with sigaction.
5425 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
5427 Rework to avoid unnecessary accesses to volatile variables.
5428 (UNBLOCK_INPUT_TO): Now a function.
5429 (totally_unblock_input, unblock_input): New decls.
5430 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
5431 (init_data): Remove. Necessary stuff now done in init_signal.
5432 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
5433 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
5434 (fatal_error_code): Remove; no longer needed.
5435 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
5436 it doesn't always backtrace. All uses changed. No need to reset
5437 signal to default, since sigaction and/or die does that for us now.
5438 Use emacs_raise (FOO), not kill (getpid (), FOO).
5439 (main): Check more-accurately whether we're dumping.
5440 Move fatal-error setup to sysdep.c
5441 * floatfns.c: Do not include "syssignal.h"; no longer needed.
5442 * gtkutil.c (xg_get_file_name, xg_get_font):
5443 Remove no-longer-needed signal-mask manipulation.
5444 * keyboard.c, process.c (POLL_FOR_INPUT):
5445 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
5446 * keyboard.c (read_avail_input): Remove.
5447 All uses replaced by gobble_input.
5448 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
5449 (kbd_buffer_store_event_hold, gobble_input):
5450 (record_asynch_buffer_change) [USABLE_SIGIO]:
5451 (store_user_signal_events):
5452 No need to mess with signal mask.
5453 (gobble_input): If blocking input and there are terminals, simply
5454 set pending_signals to 1 and return. All hooks changed to not
5455 worry about whether input is blocked.
5456 (process_pending_signals): Clear pending_signals before processing
5457 them, in case a signal comes in while we're processing.
5458 By convention callers now test pending_signals before calling us.
5459 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
5460 New functions, to support changes to blockinput.h.
5461 (handle_input_available_signal): Now extern.
5462 (reinvoke_input_signal): Remove. All uses replaced by
5464 (quit_count): Now volatile, since a signal handler uses it.
5465 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
5466 All callers changed. Block SIGINT only if not already blocked.
5467 Clear sigmask reliably, even if Fsignal returns, which it can.
5468 Omit unnecessary accesses to volatile var.
5469 (quit_throw_to_read_char): No need to restore sigmask.
5470 * keyboard.c (gobble_input, handle_user_signal):
5471 * process.c (wait_reading_process_output):
5472 Call signal-handling code rather than killing ourselves.
5473 * lisp.h: Include <float.h>, for...
5474 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
5475 (pending_signals): Now volatile.
5476 (syms_of_data): Now const if IEEE floating point.
5477 (handle_input_available_signal) [USABLE_SIGIO]:
5478 (terminate_due_to_signal, record_child_status_change): New decls.
5479 * process.c (create_process): Avoid disaster if memory is exhausted
5480 while we're processing a vfork, by tightening the critical section
5482 (send_process_frame, process_sent_to, handle_pipe_signal)
5483 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
5485 (send_process): No need for setjmp/longjmp any more, since the
5486 SIGPIPE stuff is now gone. Instead, report an error if errno
5488 (record_child_status_change): Now extern. PID and W are now args.
5489 Return void, not bool. All callers changed.
5490 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
5491 Remove. All uses removed. This bug should be fixed now in a
5493 (wait_for_termination_1): Use waitpid rather than sigsuspend,
5494 and record the child status change directly. This avoids the
5495 need to futz with the signal mask.
5496 (process_fatal_action): Move here from emacs.c.
5497 (emacs_sigaction_flags): New function, containing
5498 much of what used to be in emacs_sigaction_init.
5499 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
5500 caught by emacs, to make races less likely.
5501 (deliver_process_signal): Rename from handle_on_main_thread.
5503 (BACKTRACE_LIMIT_MAX): Now at top level.
5504 (thread_backtrace_buffer, threadback_backtrace_pointers):
5506 (deliver_thread_signal, deliver_fatal_thread_signal):
5507 New functions, for more-accurate delivery of thread-specific signals.
5508 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
5509 (deliver_arith_signal): Handle in this thread, not
5510 in the main thread, since it's triggered by this thread.
5511 (maybe_fatal_sig): New function.
5512 (init_signals): New arg DUMPING so that we can be more accurate
5513 about whether we're dumping. Caller changed.
5514 Treat thread-specific signals differently from process-general signals.
5515 Block all signals while handling fatal error; that's safer.
5516 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
5518 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
5519 Ignore SIGPIPE unless batch.
5520 (emacs_backtrace): Output backtrace for the appropriate thread,
5521 which is not necessarily the main thread.
5522 * syssignal.h: Include <stdbool.h>.
5523 (emacs_raise): New macro.
5524 * xterm.c (x_connection_signal): Remove; no longer needed
5525 now that we use sigaction.
5526 (x_connection_closed): No need to mess with sigmask now.
5527 (x_initialize): No need to reset SIGPIPE handler here, since
5528 init_signals does this for us now.
5530 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
5532 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
5533 background rect may be larger (Bug#12245).
5535 2012-09-23 Chong Yidong <cyd@gnu.org>
5537 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
5539 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
5541 * .gdbinit: Just stop at fatal_error_backtrace.
5542 See Stefan Monnier's request in
5543 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
5544 Remove no-longer-used query of system type.
5546 2012-09-22 Chong Yidong <cyd@gnu.org>
5548 * search.c (Freplace_match): Doc fix (Bug#12325).
5550 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
5552 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
5553 (Fline_end_position): Doc fix.
5555 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
5557 2012-09-22 Chong Yidong <cyd@gnu.org>
5559 * dispextern.h (struct image_type): Add new slot, storing a type
5560 initialization function.
5562 * image.c (define_image_type): Call the image initializer function
5563 if it is defined. Arguments and return value changed.
5564 (valid_image_p, make_image): Callers changed.
5565 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
5566 (gif_type, imagemagick_type, svg_type, gs_type):
5567 Add initialization functions.
5568 (Finit_image_library): Call lookup_image_type.
5569 (CHECK_LIB_AVAILABLE): Macro deleted.
5570 (lookup_image_type): Call define_image_type here, rather than via
5571 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
5572 (syms_of_image): Move define_image_type calls for xbm_type and
5573 pbm_type to lookup_image_type.
5575 2012-09-22 Eli Zaretskii <eliz@gnu.org>
5577 * keyboard.c (timer_check_2): Move calculation of 'timers' and
5578 'idle_timers' from here ...
5579 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
5580 lists, to avoid infloops when the timer does something stupid,
5581 like reinvoke itself with the same or smaller time-out.
5584 2012-09-22 Martin Rudalics <rudalics@gmx.at>
5586 * window.c (Fsplit_window_internal): Handle only Qt value of
5587 Vwindow_combination_limit separately.
5588 (Qtemp_buffer_resize): New symbol.
5589 (Vwindow_combination_limit): New default value.
5592 2012-09-22 Eli Zaretskii <eliz@gnu.org>
5594 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
5595 the new overlay string. (Bug#10159)
5597 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
5599 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
5600 or that fprintf is async-signal-safe. POSIX doesn't require
5603 2012-09-22 Chong Yidong <cyd@gnu.org>
5605 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
5608 2012-09-22 Kenichi Handa <handa@gnu.org>
5610 * composite.c (composition_reseat_it): Handle the case that a
5611 grapheme cluster is not covered by a single font (Bug#12352).
5613 2012-09-21 Chong Yidong <cyd@gnu.org>
5615 * image.c (define_image_type): Avoid adding duplicate types to
5616 image_types (Bug#12463). Suggested by Jörg Walter.
5618 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5620 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
5621 (print_load_command_name): Add case LC_DATA_IN_CODE.
5622 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
5624 2012-09-21 Glenn Morris <rgm@gnu.org>
5626 * eval.c (Frun_hook_with_args_until_success)
5627 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
5629 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
5631 * fileio.c (Ffile_selinux_context): Only call freecon when
5632 lgetfilecon succeeded.
5633 (Fset_file_selinux_context): Likewise. (Bug#12444)
5635 2012-09-21 Eli Zaretskii <eliz@gnu.org>
5637 * xdisp.c (try_window_reusing_current_matrix): Under bidi
5638 reordering, locate the cursor by calling set_cursor_from_row; if
5639 that fails, clear the desired glyph matrix before returning a
5640 failure indication to the caller. Fixes leaving garbled display
5641 when fast scrolling with a down-key. (Bug#12403)
5642 (compute_stop_pos_backwards): Fix a typo that caused crashes while
5643 scrolling through multibyte text.
5645 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
5647 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
5648 calling mark_vectorlike since that's the one that marks the window.
5649 (mark_discard_killed_buffers): Mark the final cdr.
5650 * window.h (struct window): Move prev/next_buffers to the
5651 non-standard fields.
5652 * window.c (make_window): Initialize prev/next_buffers manually.
5654 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
5656 Omit unused arg EXPECTED from socket hooks.
5657 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
5658 * nsterm.m (ns_term_init):
5659 * termhooks.h (struct terminal.read_socket_hook):
5660 * w32inevt.c (w32_console_read_socket):
5661 * w32term.c (w32_read_socket):
5662 * xterm.c (XTread_socket):
5663 Omit unused arg EXPECTED. All callers changed.
5664 (store_user_signal_events): Return void, not int, since callers no
5665 longer care about the return value. All uses changed.
5667 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
5669 * w32gui.h (XParseGeometry): Do not declare.
5671 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
5673 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
5674 Ignore 'expected'. See Eli Zaretskii in
5675 <http://bugs.gnu.org/12471#8> (last line).
5677 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
5678 (XParseGeometry): Now static. Substitute extremal values for
5679 values that are out of range.
5681 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
5683 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
5685 * nsfns.m (XParseGeometry): Remove.
5686 (Fx_create_frame): Call x_set_offset to correctly interpret
5687 top_pos in geometry.
5689 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
5690 (Fx_parse_geometry): If there is a space in string, call
5691 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
5693 2012-09-17 Eli Zaretskii <eliz@gnu.org>
5695 * search.c (scan_buffer): Use character positions in calls to
5696 region_cache_forward and region_cache_backward, not byte
5697 positions. (Bug#12196)
5699 * w32term.c (w32_read_socket): Set pending_signals to 1, like
5700 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
5702 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
5703 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
5704 emacs_blocked_malloc, now deleted.
5706 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
5708 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
5709 The workaround was for improving performance on Solaris 2.4, but
5710 is getting in the way now. Emacs will still work if someone is
5711 still running Solaris 2.4 in a museum somewhere; Sun dropped
5712 support for Solaris 2.4 in 2003.
5713 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
5714 * process.c (create_process) [HAVE_WORKING_VFORK]:
5715 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
5716 since Emacs no longer uses vfork on that platform.
5718 2012-09-17 Glenn Morris <rgm@gnu.org>
5720 * emacs.c: Use COPYRIGHT.
5722 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
5724 Remove configure's --without-sync-input option (Bug#12450).
5725 When auditing signal-handling in preparation for cleaning it up,
5726 I found that SYNC_INPUT has race conditions and would be a real
5727 pain to fix. Since it's an undocumented and deprecated
5728 configure-time option, now seems like a good time to remove it.
5729 Also see <http://bugs.gnu.org/11080#16>.
5730 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
5731 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
5732 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
5733 (malloc_hysteresis):
5734 (check_depth) [XMALLOC_OVERRUN_CHECK]:
5735 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
5736 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
5737 (dont_register_blocks, bytes_used_when_reconsidered)
5738 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
5739 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
5740 [!SYSTEM_MALLOC && !SYNC_INPUT]:
5741 Remove. All uses removed.
5742 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
5743 implementation, one that depends on whether the new macro
5744 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
5746 * atimer.c (run_timers, handle_alarm_signal):
5747 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
5748 (handle_async_input, process_pending_signals)
5749 (handle_input_available_signal, init_keyboard):
5750 * nsterm.m (ns_read_socket):
5751 * process.c (wait_reading_process_output):
5752 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
5753 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
5755 * xterm.c (XTread_socket):
5757 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
5758 * eval.c (handling_signal): Remove. All uses removed.
5759 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
5760 All uses replaced with the SYNC_INPUT version.
5761 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
5763 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5766 * font.c (Ffont_shape_gstring): Remove unused local.
5768 2012-09-16 Glenn Morris <rgm@gnu.org>
5770 * Makefile.in (clean): No longer run nextstep's clean.
5772 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
5774 (ns-app): Move here from ns.mk, and simplify.
5775 (clean): Simplify nextstep entry.
5776 * ns.mk: Remove file.
5778 2012-09-17 Kenichi Handa <handa@gnu.org>
5780 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
5781 not covert the last few charactes.
5783 2012-09-16 Kenichi Handa <handa@gnu.org>
5785 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
5786 here, but just check the validity of glyphs in the glyph-string.
5788 2012-09-16 Martin Rudalics <rudalics@gmx.at>
5790 * window.c (Fwindow_parameter, Fset_window_parameter):
5791 Accept any window as argument (Bug#12452).
5793 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
5795 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
5796 to ns_term_init to avoid memory leak.
5798 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
5799 explicit retain/release.
5800 (ns_term_init): Only allow one display. Initialize outerpool and
5803 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
5805 Port _setjmp fix to POSIXish hosts as well as Microsoft.
5806 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
5807 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
5808 the Microsoft problem in a different way, by altering ../nt/config.nt.
5810 2012-09-15 Eli Zaretskii <eliz@gnu.org>
5825 * w16select.c: Remove inclusion of setjmp.h, as it is now included
5826 by lisp.h. This completes removal of setjmp.h inclusion
5827 erroneously announced in the previous commit. (Bug#12446)
5829 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
5832 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
5833 not defined as a macro. The latter happens on MS-Windows.
5836 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
5838 Port better to POSIX hosts lacking _setjmp (Bug#12446).
5839 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
5840 Some instances of '#include <setjmp.h>' removed, if the
5841 only reason for the instance was because "lisp.h" was included.
5842 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
5843 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
5844 and _longjmp with the new symbols. Emacs already uses _setjmp if
5845 available, so this change affects only POSIXish hosts that have
5846 sigsetjmp but not _setjmp, such as some versions of Solaris and
5847 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
5848 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
5849 (png_load_body) [HAVE_PNG]:
5850 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
5851 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
5852 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
5853 since PNG requires jmp_buf. This is the only exception to the
5854 general rule that we now use sys_setjmp and sys_longjmp.
5855 This exception is OK since this code does not change the signal
5856 mask or longjmp out of a signal handler.
5858 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
5860 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
5861 Include "syssignal.h", for 'main_thread'.
5863 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
5865 Avoid out-of-range marker position (Bug#12426).
5866 * insdel.c (replace_range, replace_range_2):
5867 Adjust markers before overlays, as suggested by comments.
5868 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
5869 Remove redundant check before calling offset_intervals.
5871 2012-09-14 Martin Rudalics <rudalics@gmx.at>
5873 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
5874 current buffer (Bug#12387).
5876 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
5878 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
5880 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
5882 Use a more backwards-compatible timer format (Bug#12430).
5883 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
5884 vector element, not from the 4th, since PSECS is now at the end.
5885 (Fcurrent_idle_time): Doc fix.
5887 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
5889 Function to mark objects and remove killed buffers at once.
5890 * alloc.c (discard_killed_buffers): Rename to ...
5891 (mark_discard_killed buffers) ... new name. Add marking
5892 of remaining objects. Fix comment. Adjust users.
5893 (mark_object): Do not touch frame buffer lists here.
5894 * frame.c (delete_frame): Reset frame buffer lists here.
5896 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
5898 Better workaround for GNOME bug when --enable-gcc-warnings.
5899 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
5900 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
5901 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
5903 Simplify SIGIO usage (Bug#12408).
5904 The code that dealt with SIGIO was crufty and confusing, e.g., it
5905 played tricks like "#undef SIGIO" but these tricks were not used
5906 consistently. Simplify mostly by not #undeffing standard symbols,
5907 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
5908 or not as we please) rather than "defined SIGIO" (standard symbol
5909 that we probably shouldn't #undef).
5910 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
5911 Modules that need it can include it.
5912 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
5913 * dispextern.h (ignore_sigio): New decl.
5914 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
5915 unconditionally, since it's now a no-op if !USABLE_SIGIO.
5916 * emacs.c (shut_down_emacs):
5917 * keyboard.c (kbd_buffer_store_event_hold):
5918 Use ignore_sigio rather than invoking 'signal' directly.
5919 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
5921 (FIONREAD, SIGIO): Do not #undef.
5922 (tty_read_avail_input): Use #error rather than a syntax error.
5923 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
5924 for I_PIPE, used by SETUP_SLAVE_PTY.
5925 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
5926 * sysdep.c (croak): Remove; no longer needed. This bit of
5927 temporary code, with Fred N. Fish's comment that it's temporary,
5928 has been in Emacs since at least 1992!
5929 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
5930 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
5931 * syssignal.h (croak): Remove decl.
5932 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
5933 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
5934 now that we're termios-only.
5935 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
5936 * term.c (dissociate_if_controlling_tty): Use #error rather than
5939 Work around GCC and GNOME bugs when --enable-gcc-warnings.
5940 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
5941 to work around GNOME bug 683906.
5942 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
5943 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
5944 This works around GCC bug 54561.
5946 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
5948 More fixes for 'volatile' and setjmp/longjmp.
5949 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
5950 * image.c (struct png_load_context) [HAVE_PNG]: New type.
5951 (png_load_body) [HAVE_PNG]:
5952 (jpeg_load_body) [HAVE_JPEG]:
5953 New function, with most of the old parent function's body.
5954 (png_load) [HAVE_PNG]:
5955 (jpeg_load) [HAVE_JPEG]:
5956 Invoke the new function, to avoid longjmp munging our locals.
5957 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
5958 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
5959 longjmp is passed 2, as the C standard doesn't guarantee this.
5960 Instead, store the failure code into mgr->failure_code.
5962 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5964 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
5965 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
5966 (syms_of_keyboard): Remove support for unread-command-char.
5968 2012-09-12 Eli Zaretskii <eliz@gnu.org>
5970 * w32proc.c (sys_kill): If PID is our process ID and the signal is
5971 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
5972 violation. (Bug#12426)
5974 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
5976 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
5978 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5980 * eval.c: Add `inhibit-debugger'.
5981 (Qinhibit_debugger): New symbol.
5982 (call_debugger): Bind it instead of Qdebug_on_error.
5983 (maybe_call_debugger): Test Vinhibit_debugger.
5984 (syms_of_eval): Define inhibit-debugger.
5985 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
5986 (syms_of_xdisp): Remove inhibit-debug-on-message.
5988 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5990 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
5991 If a nonvolatile local variable is written before a _longjmp to
5992 the frame containing the variable, and is read after the _longjmp,
5993 the value read is indeterminate. Some local variables of type
5994 'struct handler' and 'struct catchtag' are used in this way, so
5995 mark each of their slots as volatile if the slot can be set before
5996 _longjmp and read afterwards.
5997 * lisp.h (struct handler): var and chosen_clause are now volatile.
5998 (struct catchtag): val, next, and pdlcount are now volatile.
6000 * bidi.c (bidi_push_it, bidi_pop_it):
6001 * fns.c (copy_hash_table):
6002 * image.c (define_image_type):
6003 * keyboard.c (kbd_buffer_store_event_hold):
6004 * process.c (Fprocess_send_eof):
6005 * xfaces.c (x_create_gc) [HAVE_NS]:
6006 * xgselect.c (xg_select):
6007 Prefer assignment to memcpy when either will do.
6009 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
6010 Use pointer-to-a-pointer to simplify and avoid a NILP check each
6011 time an item is removed. No need to mark this function 'inline';
6012 the compiler knows better than we do.
6014 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
6016 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
6017 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
6018 to change_frame_size (Bug#12388).
6019 (windowDidResize:): Pass YES to updateFrameSize.
6021 * nsterm.h: Add delay parameter to updateFrameSize.
6023 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
6025 Discard killed buffers from deleted window and frame objects.
6026 This reduces an amount of references to killed buffers and
6027 helps GC to reclaim them faster.
6028 * alloc.c (discard_killed_buffers): New function.
6029 (mark_object): Use it for deleted windows and frames.
6030 (mark_object): If symbol's value is set up for a killed buffer
6031 or deleted frame, restore its global binding.
6032 * data.c (swap_in_global_binding): Add GC notice.
6033 (swap_in_symval_forwarding): Use convenient set_blv_where.
6034 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
6035 * window.h: ... to here.
6037 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
6039 Convenient macro to check whether the buffer is live.
6040 * buffer.h (BUFFER_LIVE_P): New macro.
6041 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
6042 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
6044 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6046 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
6047 composition cases (Bug#12364).
6049 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
6050 overhang of succeeding glyphs overlapping box cursor.
6052 * w32term.c (x_draw_glyph_string): Likewise.
6054 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
6056 Simplify, document, and port floating-point (Bug#12381).
6057 The porting part of this patch fixes bugs on non-IEEE platforms
6058 with frexp, ldexp, logb.
6059 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
6061 * floatfns.c: Simplify discussion of functions that Emacs doesn't
6062 support, by removing commented-out code and briefly listing the
6063 C89 functions excluded. The commented-out stuff was confusing
6064 maintenance, e.g., we thought we needed cbrt but it was commented out.
6065 (logb): Remove decl; no longer needed.
6066 (isfinite): New macro, if not already supplied.
6067 (isnan): Don't replace any existing macro.
6068 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
6069 are present on all C89 platforms.
6070 (Ffrexp): Do not special-case zero, as frexp does the right thing
6072 (Flogb): Do not use logb, as it doesn't have the desired meaning
6073 on hosts that use non-base-2 floating point. Instead, stick with
6074 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
6075 frexp, to avoid getting an unspecified result.
6077 * xdisp.c (Qinhibit_debug_on_message): Now static.
6079 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
6081 * nsterm.m (ns_update_begin): Set clip path to whole view by using
6082 NSBezierPath (Bug#12131).
6084 2012-09-10 Chong Yidong <cyd@gnu.org>
6086 * fns.c (Fdelq, Fdelete): Doc fix.
6088 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
6090 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
6091 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
6093 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
6095 * lisp.h (make_lisp_ptr): New macro to replace XSET.
6096 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
6099 2012-09-09 Eli Zaretskii <eliz@gnu.org>
6101 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
6102 left fringe if the window has a left margin. This avoids leaving
6103 traces of the cursor because its leftmost pixel is not drawn over.
6105 * dispnew.c (update_window_line): When the left margin area of a
6106 screen line is updated, set the redraw_fringe_bitmaps_p flag of
6107 that screen line. (Bug#12277)
6109 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
6111 Assume C89 or later for math functions (Bug#12381).
6112 This simplifies the code, and makes it a bit smaller and faster,
6113 and (most important) makes it easier to clean up signal handling
6114 since we can stop worring about floating-point exceptions in
6115 library code. That was a problem before C89, but the problem
6116 went away many years ago on all practical Emacs targets.
6117 * data.c, image.c, lread.c, print.c:
6118 Don't include <math.h>; no longer needed.
6119 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
6120 might be autoconfigured, as that never happens.
6122 * doprnt.c (DBL_MAX_10_EXP):
6123 * print.c (DBL_DIG):
6124 Remove. C89 or later always defines these.
6125 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
6126 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
6127 (arith_error, domain_error, domain_error2):
6128 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
6129 no longer needed -- we simply return what C returns. All uses removed.
6130 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
6132 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
6133 Remove. All uses expanded, as these macros are no longer used
6134 more than once and are now more trouble than they're worth.
6135 (Ftan): Use tan, not sin / cos.
6136 (Flogb): Assume C89 frexp.
6137 (fmod_float): Assume C89 fmod.
6138 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
6139 (init_floatfns): Remove. All uses removed.
6141 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6143 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
6144 compositeToPoint for OSX < 10.6 (Bug#12390).
6146 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
6148 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
6149 This produces more-accurate results.
6151 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6153 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
6154 changes (Bug#12088).
6156 2012-09-08 Chong Yidong <cyd@gnu.org>
6158 * syntax.c (Fstring_to_syntax): Doc fix.
6160 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6162 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
6163 in the internal border.
6164 (x_set_window_size): Remove static variables and their usage.
6165 (ns_redraw_scroll_bars): Fix NSTRACE arg.
6166 (ns_after_update_window_line, ns_draw_fringe_bitmap):
6167 Remove fringe/internal border adjustment (Bug#11052).
6168 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
6169 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
6170 (ns_fix_rect_ibw): Remove.
6171 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
6172 (ns_dumpglyphs_box_or_relief): Ditto.
6173 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
6175 (ns_dumpglyphs_image): Ditto.
6176 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
6178 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
6179 their usage. Add fringe_extended_p and its use as in other terms.
6180 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
6181 scroll bar was removed.
6182 (updateFrameSize): New function.
6183 (windowDidResize): Move code to updateFrameSize and call it.
6185 * nsterm.h (EmacsView): Add updateFrameSize.
6187 2012-09-07 Chong Yidong <cyd@gnu.org>
6189 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
6191 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
6193 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
6195 More signal-handler cleanup (Bug#12327).
6196 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
6197 Problem introduced when merging patches. Noted by Eli Zaretskii in
6198 <http://bugs.gnu.org/12327#67>.
6199 * floatfns.c: Comment fix.
6200 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
6201 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
6202 and anyway the declaration is harmless even if SIGDANGER is not defined.
6203 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
6204 defined BROKEN_FIONREAD). systty.h formerly did this, but other
6205 source files not surprisingly expected syssignal.h to define, or
6206 not define, SIGIO, and it's cleaner to do it that way, for consistency.
6207 Include <sys/ioctl.h>, for FIONREAD.
6208 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
6209 This eliminates a problem whereby other files mysteriously had
6210 to include "syssignal.h" before including "systty.h" if they
6211 wanted to use "#ifdef SIGIO".
6213 2012-09-07 Eli Zaretskii <eliz@gnu.org>
6215 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
6217 * w32.c (sigemptyset): Empty the set.
6218 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
6220 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
6222 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
6224 * alloc.c (mark_buffer): Revert unsafe marking optimization.
6225 (mark_object): Likewise for frame objects.
6227 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
6229 * syssignal.h (handle_on_main_thread): Always declare,
6230 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
6231 This ports to platforms without HAVE_PTHREAD.
6233 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
6235 Signal-handler cleanup (Bug#12327).
6236 Emacs's signal handlers were written in the old 4.2BSD style with
6237 sigblock and sigmask and so forth, and this led to some
6238 inefficiencies and confusion. Rewrite these to use
6239 pthread_sigmask etc. without copying signal sets around. Also,
6240 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
6241 'signal', and instead use functions that do not attempt to take
6242 over the system name space. This patch causes Emacs's text
6243 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
6244 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
6245 Do not include <signal.h> or "syssignal.h", as these
6246 modules do not use signals.
6247 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
6248 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
6249 Do not include <signal.h>, as "syssignal.h" does that for us now.
6250 * atimer.c (sigmask_atimers): New function.
6251 (block_atimers, unblock_atimers): New functions,
6252 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
6254 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
6255 no longer needed here.
6256 * emacs.c (main): Inspect existing signal handler with sigaction,
6257 so that there's no need to block and unblock SIGHUP.
6258 * sysdep.c (struct save_signal): New member 'action', replacing
6259 old member 'handler'.
6260 (save_signal_handlers, restore_signal_handlers):
6261 Use sigaction instead of 'signal' to save and restore.
6262 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
6263 New function. All users of 'signal' modified to use set_sighandler
6264 if they're writeonly, and to use sys_signal if they're read+write.
6265 (emacs_sigaction_init, forwarded_signal): New functions.
6266 (sys_signal): Remove. All uses replaced by calls to sigaction
6267 and emacs_sigaction_init, or by direct calls to 'signal'.
6268 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
6269 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
6270 all uses replaced by pthread_sigmask etc. calls.
6271 * syssignal.h: Include <signal.h>.
6272 (emacs_sigaction_init, forwarded_signal): New decls.
6273 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
6274 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
6275 (sigmask, sys_sigmask): Remove; no longer needed.
6276 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
6277 (sigblock, sigunblock, sigfree):
6278 (sigsetmask) [!defined sigsetmask]:
6279 Remove. All uses replaced by pthread_sigmask.
6280 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
6281 no longer need to be replaced, and its typical old uses
6282 are now done via emacs_sigaction_init and sigaction.
6283 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
6284 (sys_sigdel): Remove; unused.
6285 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
6287 2012-09-06 Eli Zaretskii <eliz@gnu.org>
6289 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
6290 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
6292 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
6294 Explicitly mark buffer_defaults and buffer_local_symbols.
6295 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
6296 mark_local_symbols here.
6297 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
6298 since special buffers aren't marked here any more.
6299 (allocate_buffer): Chain new buffer with all_buffers here...
6300 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
6302 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
6303 (syms_of_buffer): Remove staticpro of the above.
6304 (init_buffer_once): Set names for buffer_defaults and
6305 buffer_local_symbols.
6307 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
6309 Use bool for booleans in font-related modules.
6310 * font.c (font_intern_prop, font_style_to_value)
6311 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
6312 (generate_otf_features, font_check_otf_features, font_check_otf)
6313 (font_match_p, font_list_entities, font_at):
6314 * fontset.c (fontset_id_valid_p, reorder_font_vector
6315 (fontset_find_font, Fset_fontset_font)
6316 (face_suitable_for_char_p) [0]:
6317 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
6318 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
6319 (m17n_flt_initialized, ftfont_shape_by_flt):
6320 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
6321 * nsfont.m (nsfont_draw):
6322 * w32font.c (w32font_draw):
6323 * w32term.c (x_draw_glyphless_glyph_string_foreground):
6324 Use bool for booleans.
6325 * font.h: Adjust to above API changes.
6326 (struct font, struct font_driver, struct font_driver_list):
6327 Use bool for booleans.
6328 (struct font): Remove useless member encoding_type.
6330 * fontset.c, xftfont.c: Omit unnecessary static decls.
6332 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
6334 * alloc.c (mark_object): Revert window marking code
6335 since it's unsafe for the Fset_window_configuration.
6337 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
6339 Fix race conditions with signal handlers and errno (Bug#12327).
6340 Be more systematic about preserving errno whenever a signal
6341 handler returns, even if it's not in the main thread. Do this by
6342 renaming signal handlers to distinguish between signal delivery
6343 and signal handling. All uses changed.
6344 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
6345 * data.c (deliver_arith_signal): Rename from arith_error.
6346 * dispnew.c (deliver_window_change_signal): Rename from
6347 window_change_signal.
6348 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
6349 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
6350 * keyboard.c (deliver_input_available_signal): Rename from
6351 input_available_signal.
6352 (deliver_user_signal): Rename from handle_user_signal.
6353 (deliver_interrupt_signal): Rename from interrupt_signal.
6354 * process.c (deliver_pipe_signal): Rename from send_process_trap.
6355 (deliver_child_signal): Rename from sigchld_handler.
6356 * atimer.c (handle_alarm_signal):
6357 * data.c (handle_arith_signal):
6358 * dispnew.c (handle_window_change_signal):
6359 * emacs.c (handle_fatal_signal, handle_danger_signal):
6360 * keyboard.c (handle_input_available_signal):
6361 * keyboard.c (handle_user_signal, handle_interrupt_signal):
6362 * process.c (handle_pipe_signal, handle_child_signal):
6363 New functions, with the actual signal-handling code taken from the
6364 original respective signal handlers, sans the sporadic attempts to
6365 preserve errno, since that's now done by handle_on_main_thread.
6366 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
6367 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
6368 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6370 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6371 Move initialization of main_thread to sysdep.c's init_signals.
6372 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
6373 our usage, and simplifies the mainline code.
6374 (record_child_status_change): New static function, as a helper
6375 for handle_child_signal, and with most of the old child handler's
6377 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
6378 (handle_child_signal): Use the above.
6379 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6380 Moved here from emacs.c.
6381 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
6382 code moved here from emacs.c's main function.
6383 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
6384 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
6385 This lets callers save and restore errno properly.
6387 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6389 Remove redundant or unused things here and there.
6390 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
6391 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
6392 * editfns.c (Fcompare_buffer_substrings): Likewise.
6393 * frame.h (struct terminal, struct font_driver_list):
6394 Remove redundant declarations.
6395 * window.h (Qleft, Qright): Likewise.
6397 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6399 Do not mark objects from deleted buffers, windows and frames.
6400 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
6401 (mark_object): Likewise for windows and frames.
6403 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6405 * alloc.c (valid_lisp_object_p): Treat killed buffers,
6406 buffer_defaults and buffer_local_symbols as valid objects.
6407 Return special value to denote them.
6409 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
6411 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
6412 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
6413 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
6414 (file_name_absolute_p, Fsubstitute_in_file_name):
6415 (check_executable, check_writable, Ffile_accessible_directory_p)
6416 (Fset_file_selinux_context, Fdefault_file_modes)
6417 (Finsert_file_contents, choose_write_coding_system)
6418 (Fwrite_region, build_annotations, a_write, e_write)
6420 * filelock.c (boot_time_initialized, get_boot_time)
6421 (get_boot_time_1, lock_file_1, within_one_second):
6422 * floatfns.c (in_float):
6423 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
6424 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
6425 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
6426 * lisp.h (struct Lisp_Hash_Table.cmpfn):
6427 * window.c (compare_window_configurations):
6428 Use bool for booleans.
6429 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
6430 (Fdefault_file_modes): Now mode_t, not int, for modes.
6431 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
6432 (internal_delete_file): Now returns void, not a (boolean) int,
6433 since nobody was looking at the return value.
6434 * lisp.h, window.h: Adjust to above API changes.
6436 * xdisp.c (set_message): Simplify and reindent last change.
6438 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
6440 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
6442 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
6444 * eval.c (call_debugger): Make the function non-static so that we
6445 can call it from set_message.
6447 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
6448 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
6450 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6452 Give more-useful info on a fatal error (Bug#12328).
6453 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
6454 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
6455 of doing the work ourselves.
6456 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
6457 do most of the work.
6458 (fatal_error_backtrace): New function, taken from the guts
6459 of the old fatal_error_signal, but with a new option to output
6461 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
6462 info about the signal than just its number.
6463 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
6464 * sysdep.c: Include <execinfo.h>
6465 (emacs_backtrace): New function, taken partly from the previous
6466 code of the 'die' function.
6467 (emacs_abort): Call fatal_error_backtrace rather than abort.
6469 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
6471 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
6472 eager (load-time) macro-expansion.
6473 * lisp.mk (lisp): Add macroexp.
6475 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6477 Simplify redefinition of 'abort' (Bug#12316).
6478 Do not try to redefine the 'abort' function. Instead, redo
6479 the code so that it calls 'emacs_abort' rather than 'abort'.
6480 This removes the need for the NO_ABORT configure-time macro
6481 and makes it easier to change the abort code to do a backtrace.
6482 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
6483 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
6484 Remove; sysdep.c's emacs_abort now takes its place.
6485 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
6486 'abort' changed to use 'emacs_abort'.
6487 * msdos.c (dos_abort) [defined abort]: Remove; not used.
6488 (abort) [!defined abort]: Rename to ...
6489 (emacs_abort): ... new name.
6490 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
6491 the place of the old 'abort' in emacs.c.
6492 * w32.c, w32fns.c (abort): Do not #undef.
6493 * w32.c (emacs_abort): Rename from w32_abort.
6495 2012-09-04 Eli Zaretskii <eliz@gnu.org>
6497 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
6498 offsets[j].dv, since the y axis of the screen coordinates points
6499 down, while the y axis of the font definition coordinates points
6500 up. This fixes display of Arabic diacritics such as KASRA and
6501 KASRATAN. (Bug#11860)
6503 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6505 Be more systematic about _setjmp vs setjmp.
6506 * alloc.c (test_setjmp, mark_stack):
6507 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
6508 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
6509 (png_load, my_error_exit, jpeg_load):
6510 * process.c (send_process_trap, send_process):
6511 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
6512 The underscored versions are up to 30x faster on some hosts.
6513 Formerly, the code used setjmp+longjmp sometimes and
6514 _setjmp+_longjmp at other times, with no particular reason to
6515 prefer setjmp+longjmp.
6517 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
6519 Fix minor problem found by static checking.
6520 * buffer.c (Fdelete_all_overlays): Return nil.
6522 2012-09-03 Martin Rudalics <rudalics@gmx.at>
6524 * buffer.c (Fdelete_all_overlays): New function.
6526 2012-09-03 Chong Yidong <cyd@gnu.org>
6528 * gtkutil.c: Add extern decl for Qxft.
6530 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>

6544 All callers changed.
6545 * eval.c (interactive_p): Omit always-true boolean argument
6546 EXCLUDE_SUBRS_P. All callers changed.
6547 * dispextern.h, lisp.h: Reflect above API changes.
6548 * firstfile.c (dummy): Use the address of 'main', whose signature
6549 won't change, instead of the address of 'initialize', whose
6550 signature just changed from int to bool.
6551 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
6552 * msdos.c (fatal_error_in_progress): ... from here.
6553 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
6555 (redisplay_internal, unwind_redisplay): Simply clear
6556 REDISPLAYING_P when unwinding, instead of saving its previous,
6557 always-false value and then restoring it.
6559 Clean up some extern decls.
6560 Mostly, this hoists extern decls out of .c files and into .h files.
6561 That way, we're more likely to catch errors if the interfaces change.
6562 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
6563 declare xg_mark_data.
6564 * dispextern.h (x_frame_parm_handlers):
6566 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)

6582 * xfont.c (x_clear_errors):
6583 * xterm.c (x_frame_parm_handlers):
6584 Remove now-redundant extern decls.
6585 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
6586 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
6588 * xfaces.c: Remove unnecessary static decls.
6589 * xterm.c (updating_frame): Remove decl of nonexistent object.
6591 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
6592 when building globals.h, as the objects that are not built on
6593 this host are not needed to compile C files on this host.
6595 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
6597 * gtkutil.h: Remove prototype for x_wm_set_size_hint.

6611 (make_buffer_string, make_buffer_string_both)
6612 (Fsubst_char_in_region, Ftranslate_region_internal, Fformat):

6624 (set_intervals_multibyte_1, set_intervals_multibyte):
6625 * keyboard.c (decode_timer):
6626 Use bool for boolean.
6627 * intervals.h, lisp.h, systime.h: Reflect above API changes.
6628 * editfns.c (struct info): Use 1-bit unsigned bitfields for booleans.

6635 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
6637 * makefile.w32-in (CCL_H, W32FONT_H): New macros.

6645 2012-09-01 Eli Zaretskii <eliz@gnu.org>
6647 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
6648 more than one grapheme cluster passed to the shaper: compute the
6649 offset adjustment values separately for each cluster. (Bug#11860)
6651 * image.c: Restore mistakenly removed inclusion of w32.h. Without
6652 it, GCC doesn't see prototypes of w32_delayed_load, and complains
6653 about implicit conversions from integer to pointer.
6655 2012-09-01 Daniel Colascione <dancol@dancol.org>
6657 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
6658 system used too early.
6660 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
6662 Better seed support for (random).

6703 * keyboard.c: Include TERM_HEADER instead of listing all possible
6704 window-system headers.

6711 window system declarations.
6713 * frame.h: Move common functions here: set_frame_menubar,
6714 x_set_window_size, x_sync, x_get_focus_frame,
6715 x_set_mouse_position, x_set_mouse_pixel_position,
6716 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

6740 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
6742 Remove mark_ttys function and fix tty_display_info initialization.
6743 * lisp.h (mark_ttys): Remove prototype.
6744 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
6745 to mark_ttys because all possible values of 'top_frame' slot are
6746 the frames which are reachable from Vframe_list.
6747 * term.c (mark_ttys): Remove.
6748 (init_tty): Safely initialize 'top_frame' slot with Qnil.
6750 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>

6755 'auto_raise', 'auto_lower', 'no_split', 'explicit_name',
6756 'window_sizes_changed', 'mouse_moved' and 'pointer_invisible'
6757 bitfields from unsigned char to unsigned.

6770 2012-08-30 Paul Eggert <eggert@cs.ucla.edu>
6772 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
6773 for GCC 4.7.1 x86-64.
6775 2012-08-30 Glenn Morris <rgm@gnu.org>
6777 * lread.c (init_lread): For out-of-tree builds, only add the
6778 source directory's site-lisp dir to the load-path if it exists,
6779 consistent with in-tree builds. (Bug#12302)
6781 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>
6783 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize

6793 (addSplit): Remove return self, declare return value as void.
6794 (clicked:): Remove return self, declare return value as void.
6795 Set dialog_return to button_values[seltag]. Code formatting change.

6797 Code formatting change.
6798 (timeout_handler:): Set timer_fired to YES.
6799 (runDialogAt:): Set timer_fired to NO.
6800 Handle click on close button as quit.
6802 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
6803 Add window_closed and button_values. Add void as return value for
6804 add(Button|String|Split). addButton takes int instead of Lisp_Object.
6805 Add process_dialog as new member.
6807 2012-08-28 Eli Zaretskii <eliz@gnu.org>
6809 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it
6810 is not one of the heaps we manage. (Bug#12242)

6869 (do_pending_window_change, change_frame_size)
6870 (change_frame_size_1, sit_for):
6871 Use bool for boolean.
6872 (clear_glyph_matrix_rows): Rename from enable_glyph_matrix_rows,
6873 and remove last int (actually boolean) argument, which was always 0.
6874 All callers changed.
6875 * dispextern.h, frame.h, lisp.h: Reflect above API changes.
6876 * dispextern.h (struct composition_it): Use bool for boolean.
6877 (struct glyph_matrix): Don't assume buffer sizes can fit in 'int'.
6878 (struct bidi_it): Use unsigned:1, not int, for boolean prev_was_pdf.
6879 * dired.c (file_name_completion):
6880 Use bool for boolean. (This was missed in an earlier change.)
6882 2012-08-27 Martin Rudalics <rudalics@gmx.at>
6884 * window.c (Fset_window_configuration): Revert first part of
6887 2012-08-27 Jan Djärv <jan.h.d@swipnet.se>
6889 * nsterm.h (NSPanel): New class variable dialog_return.
6891 * nsmenu.m (initWithContentRect:styleMask:backing:defer:):
6892 Initialize dialog_return.
6893 (windowShouldClose:): Use stop instead of stopModalWithCode.
6894 (clicked:): Ditto, and also set dialog_return (Bug#12258).
6895 (timeout_handler:): Use stop instead of abortModal. Send a dummy
6897 (runDialogAt:): Make ret Lisp_Object. Set it from dialog_return when
6900 2012-08-27 Paul Eggert <eggert@cs.ucla.edu>
6902 * composite.c, data.c, dbusbind.c, dired.c: Use bool for booleans.
6903 * composite.c (find_composition, composition_gstring_p)
6904 (composition_reseat_it, find_automatic_composition):

6912 Use bool for booleans.
6913 * dired.c (file_name_completion):
6914 * process.h (fd_callback):
6915 Omit int (actually boolean) argument. It wasn't being used.
6917 * composite.h, lisp.h: Reflect above API changes.
6919 * cmds.c, coding.c: Use bool for booleans.
6920 * cmds.c (move_point, Fself_insert_command):

6940 (Fset_coding_system_priority):
6941 * fileio.c (Finsert_file_contents):
6942 Use bool for booleans.
6943 * coding.h, lisp.h: Reflect above API changes.
6944 * coding.c: Remove unnecessary static function decls.
6945 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
6946 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
6947 not a boolean 'int', since callers never look at the return value.
6948 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
6949 * coding.h (decoding_buffer_size, encoding_buffer_size)
6950 (emacs_mule_string_char): Remove unused extern decls.
6951 (struct iso_2022_spec, struct coding_system):
6952 Use 'unsigned int : 1' for boolean fields, since there's more than one.
6953 (struct emacs_mule_spec): Remove unused field 'full_support'.
6954 All initializations removed.
6955 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
6957 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
6959 Fix spare memory change (Bug#12286).
6960 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
6961 (valid_lisp_object_p): Likewise.
6963 2012-08-27 Martin Rudalics <rudalics@gmx.at>
6965 * window.c (Fset_window_configuration): Record any window's old
6966 buffer if it's replaced (see Bug#8789). If the new current
6967 buffer doesn't appear in the selected window, go to its old
6970 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
6972 Special MEM_TYPE_SPARE to denote reserved memory.
6973 * alloc.c (enum mem_type): New memory type.
6974 (refill_memory_reserve): Use new type for spare memory.
6975 This prevents live_cons_p and live_string_p from incorrect
6976 detection of uninitialized objects from spare memory as live.
6978 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
6981 * Makefile.in (.PHONY): versioclean -> versionclean.
6983 Remove unused external symbols.
6984 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
6985 * window.c (Qwindow_valid_p, decode_valid_window):
6986 Now static, not extern.
6987 * data.c (Qinterval): Remove; unused.
6988 (syms_of_data): Do not define 'interval'.
6989 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
6990 * window.h (decode_valid_window):
6993 * character.c, charset.c, chartab.c: Use bool for booleans.
6994 * character.c (lisp_string_width, string_count_byte8)
6995 (string_escape_byte8):
6996 * charset.c (charset_map_loaded, load_charset_map, read_hex):
6997 (load_charset_map_from_file, map_charset_chars)

6999 (Fdeclare_equiv_charset, find_charsets_in_text)
7000 (Ffind_charset_region, char_charset, Fiso_charset):

7002 (sub_char_table_set, sub_char_table_set_range)
7003 (char_table_set_range, optimize_sub_char_table)
7004 (map_sub_char_table):
7005 Use bool for boolean.
7006 * character.c (str_to_unibyte): Omit last boolean argument; it was
7007 always 0. All callers changed.
7008 * character.h, charset.h: Adjust to match previous changes.
7009 * character.h (char_printable_p): Remove decl of nonexistent function.
7010 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
7011 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
7012 are all boolean, so make them single-bit bitfields.
7014 * lisp.h (ASET): Remove attempt to detect side effects.
7015 It was meant to be temporary and it often doesn't work,
7016 because when IDX has side effects the behavior of IDX==IDX
7017 is undefined. See Stefan Monnier in
7018 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
7020 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
7022 * lisp.h (functionp): New function (extracted from Ffunctionp).
7023 (FUNCTIONP): Use it.
7024 * eval.c (Ffunctionp): Use it.
7026 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
7028 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
7029 as that's faster and simpler than static storage. Don't bother
7030 with the g_main_context_query overhead if g_main_context_pending
7031 says no events are pending.
7032 (gfds, gfds_size): Remove these static vars.
7033 (xgselect_initialize): Remove; no longer needed.
7034 All uses and decls removed.
7036 * emacs.c (fatal_error_signal_hook): Remove.
7037 All uses removed. This leftover from old code was always 0.
7039 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
7040 * casefiddle.c (casify_object, casify_region):
7041 * casetab.c (set_case_table):
7042 * category.c, category.h (word_boundary_p):
7043 * category.h (CHAR_HAS_CATEGORY):
7044 Use bool for booleans, instead of int.
7046 2012-08-25 Eli Zaretskii <eliz@gnu.org>
7048 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
7050 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
7052 On assertion failure, print backtrace if available.
7053 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
7054 (die) [ENABLE_CHECKING]: Print a backtrace if available.
7055 * Makefile.in (LIB_EXECINFO): New macro.
7058 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
7059 * bytecode.c (exec_byte_code):
7060 * callint.c (check_mark, Fcall_interactively):
7061 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
7062 (getenv_internal, sync_process_alive, call_process_exited):
7063 * lisp.h (USE_SAFE_ALLOCA):
7064 Use bool for booleans, instead of int.
7065 * lisp.h, process.h: Adjust prototypes to match above changes.
7066 * callint.c (Fcall_interactively): Don't assume the mark's
7067 offset fits in 'int'.
7069 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
7071 * buffer.c, buffer.h: Use bool for boolean.
7072 * buffer.c (reset_buffer_local_variables)
7073 (buffer_lisp_local_variables, Fset_buffer_modified_p)
7074 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
7075 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
7076 (overlay_touches_p, overlay_strings, Foverlay_put)
7077 (report_overlay_modification, call_overlay_mod_hooks):
7078 (mmap_enlarge, mmap_set_vars):
7079 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
7080 Use bool for booleans, instead of int.
7081 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
7082 since the 1-or-0 return value is always ignored anyway.
7083 (mmap_initialized_p):
7084 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
7085 * buffer.h, lisp.h: Adjust prototypes to match above changes.
7087 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
7089 * bidi.c: Use bool for boolean.
7090 This is a bit more readable, and makes the text segment of bidi.o
7091 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
7092 Presumably it's faster too.
7093 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
7095 (bidi_cache_find_level_change, bidi_cache_iterator_state)
7096 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
7097 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
7098 (bidi_explicit_dir_char, bidi_level_of_next_char)
7099 (bidi_find_other_level_edge, bidi_move_to_visually_next):
7100 Use bool for booleans, instead of int.
7101 * dispextern.h (bidi_init_it, bidi_paragraph_init)
7102 (bidi_unshelve_cache): Adjust decls to match code.
7104 2012-08-23 Martin Rudalics <rudalics@gmx.at>
7106 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
7109 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
7111 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
7112 * atimer.h: Include <stdbool.h>.
7114 2012-08-22 Dan Nicolaescu <dann@gnu.org>
7116 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
7117 compile time tests instead of run time tests on systems that do
7119 (FRAME_MAC_P): Remove leftover from deleted code.
7120 * frame.c (syms_of_frame): Remove leftover from deleted code.
7122 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
7124 * nsterm.m (insertText:): Don't clear modifiers if code is space.
7126 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
7128 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
7129 Otherwise, the compiler complains about (A?B:C) where B is void
7130 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
7131 (fontset_add): Return void, for FONTSET_ADD.
7133 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7135 * alloc.c: Use bool for booleans.
7136 (gc_in_progress, abort_on_gc)
7137 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
7138 (dont_register_blocks) [GC_MALLOC_CHECK]:
7139 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
7140 (check_string_bytes, make_specified_string, memory_full)
7141 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
7142 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
7143 (mark_stack, valid_pointer_p, make_pure_string)
7144 (Fgarbage_collect, survives_gc_p, gc_sweep):
7145 Use bool for booleans, instead of int.
7146 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
7147 Remove unused local.
7148 * alloc.c (PURE_POINTER_P):
7149 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
7150 * editfns.c (Fformat):
7151 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
7153 * fns.c (sweep_weak_table):
7154 * lisp.h (suppress_checking, push_message, survives_gc_p)
7155 (make_pure_string, gc_in_progress, abort_on_gc):
7156 * lread.c (readchar, read1):
7157 * print.c (Fprin1_to_string):
7158 * xdisp.c (push_message):
7159 Use bool for booleans affected directly or indirectly by
7162 Make recently-introduced setters macros.
7163 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
7164 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
7165 (set_fontset_default, set_fontset_fallback): Rename from their
7166 upper-case counterparts, and make them functions rather than macros.
7167 This is more consistent with the other recently-introduced setters.
7168 These don't need to be inline, since they're local.
7170 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
7172 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
7173 the loop (Bug#12247).
7175 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7177 * lisp.h (vcopy): Use memcpy rather than our own loop.
7178 This fixes a performance regression introduced by the recent
7179 addition of vcopy. This means 'vcopy' will need to be modified
7180 for a copying collector, but that's OK. Also, tighten the
7181 checking in the assertion.
7183 2012-08-21 Eli Zaretskii <eliz@gnu.org>
7185 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
7186 components for RTL text (Bug#11860). Adjust X-OFFSET of each
7187 non-base glyph for the width of the base character, according to
7188 what x_draw_composite_glyph_string_foreground expects.
7189 Generate WADJUST value according to composition_gstring_width's
7190 expectations, to produce correct width of the composed character.
7191 Reverse the sign of the DU offset produced by ScriptPlace.
7193 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7195 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
7197 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
7199 Avoid direct writes to contents member of struct Lisp_Vector.
7200 * lisp.h (vcopy): New function to copy data into vector.
7201 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
7202 * fns.c (Ffillarray): Use ASET.
7203 * keyboard.c (timer_check_2): Use AREF and ASET.
7204 (append_tool_bar_item, Frecent_keys): Use vcopy.
7205 * lread.c (read_vector): Use ASET.
7206 * msdos.c (Frecent_doskeys): Use vcopy.
7207 * xface.c (Finternal_copy_lisp_face): Use vcopy.
7208 (Finternal_merge_in_global_face): Use ASET and vcopy.
7209 * xfont.c (xfont_list_pattern): Likewise.
7211 2012-08-21 Martin Rudalics <rudalics@gmx.at>
7213 * window.c (Fwindow_point): For the selected window always return
7214 the position of its buffer's point.
7215 (Fset_window_point): For the selected window always go in its
7216 buffer to the specified position.
7218 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
7220 Setter macros for fontsets.
7221 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
7222 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
7223 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
7226 2012-08-20 Glenn Morris <rgm@gnu.org>
7228 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
7229 Don't assume that `ln -f' works.
7231 2012-08-20 Eli Zaretskii <eliz@gnu.org>
7233 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
7234 and later about non-assignments with no effect. See discussion at
7235 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
7238 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7240 Inline setter functions for Lisp_Objects slots of struct specbinding.
7241 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
7244 2012-08-20 Martin Rudalics <rudalics@gmx.at>
7246 * window.c (select_window): Always make selected window's buffer
7249 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7251 Use AREF and ASET for docstrings of category tables.
7252 * category.h (CATEGORY_DOCSTRING): Use AREF.
7253 (SET_CATEGORY_DOCSTRING): Use ASET.
7254 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
7256 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7258 Inline setter functions for hash table members.
7259 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
7260 (set_hash_hash, set_hash_index): Rename with _slot suffix.
7261 (set_hash_key_and_value, set_hash_index, set_hash_next)
7262 (set_hash_hash): New functions.
7263 * charset.c, fns.c: Adjust users.
7265 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7267 Inline getter and setter functions for per-buffer values.
7268 * buffer.h (per_buffer_default, set_per_buffer_default)
7269 (per_buffer_value, set_per_buffer_value): New functions.
7270 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
7271 * buffer.c, data.c: Adjust users.
7273 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
7275 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
7277 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
7279 Rely on <config.h> + <unistd.h> to declare 'environ',
7280 as gnulib does this if the system doesn't.
7281 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
7282 Remove declaration. MS-Windows declares it on stdlib.h which is
7283 included by conf_post.h.
7284 * emacs.c (environ) [DOUG_LEA_MALLOC]:
7285 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
7286 * vm-limit.c: Include <unistd.h>, for 'environ'.
7288 * unexaix.c, unexcoff.c: Include "mem-limits.h".

7705 Use bool, not int, for Lisp booleans.
7706 This is more natural, and on my platform (GCC 4.7.1 x86-64) it

8160 called when Vload_path is already set up.
8162 * w32.h (check_windows_init_file): Add prototype.
8164 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build
8165 directory, ignore the /*/i386/ tail in Vinvocation_directory, for
8166 compatibility with Posix platforms.
8167 (main): Move the call to check_windows_init_file to here from
8169 (decode_env_path) [WINDOWSNT]: Expand the %emacs_dir%/ prefix, if
8170 any, in the DEFALT argument into the root of the Emacs build or
8171 installation tree, as appropriate.
8173 * callproc.c (init_callproc_1): Call decode_env_path instead of
8174 doing its equivalent by hand.
8175 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
8176 the code that sets Vexec_path run on MS-Windows.
8178 * lread.c (init_lread): Add comments to #ifdef's.
8180 * msdos.c (dos_set_window_size, IT_update_begin)
8181 (IT_frame_up_to_date, IT_set_frame_parameters): Use FVAR and WVAR
8182 instead of direct references.
8184 2012-08-04 Paul Eggert <eggert@cs.ucla.edu>
8186 Export DEFAULT_REHASH_* to GDB.
8187 * lisp.h (DEFAULT_REHASH_THRESHOLD, DEFAULT_REHASH_SIZE):
8188 Now constants, not macros.
8190 2012-08-03 Paul Eggert <eggert@cs.ucla.edu>
8192 Remove unnecessary casts involving pointers.
8193 These casts are no longer needed now that we assume C89 or later,
8194 since they involve casting to or from void *.
8195 * alloc.c (make_pure_string, make_pure_c_string, pure_cons)
8196 (make_pure_float, make_pure_vector):
8197 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP):

8206 (x_get_window_property, x_get_window_property_as_lisp_data):
8207 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
8208 Remove unnecessary pointer casts.
8209 * alloc.c (record_xmalloc): New function.
8210 * lisp.h (record_xmalloc): New decl.
8211 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
8212 more like a function. This is because the pointer cast is not
8213 needed. All uses changed.
8214 * print.c (print_string, print_error_message): Avoid length recalc.
8216 Improve fix for macroexp crash with debugging (Bug#12118).
8217 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
8218 ARRAY_MARK_FLAG when checking subscripts, because ASET is
8219 not supposed to be invoked from the garbage collector.
8220 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
8221 (gc_aset): New function, which is like ASET but can be
8222 used in the garbage collector.
8223 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)
8224 (set_hash_index): Use it instead of ASET.

8235 (GetSecurityInfo_Proc, CreateSymbolicLink_Proc): New typedefs.
8236 (map_w32_filename): Improve commentary. Simplify switch.
8237 (SYMBOLIC_LINK_FLAG_DIRECTORY): Define if not defined in system
8238 headers (most versions of MinGW w32api don't).
8239 (get_security_info, create_symbolic_link)
8240 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
8242 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
8243 in the argument file name.

8245 GetFileAttributes fails with network-related error codes.
8246 (sys_rename): Diagnose renaming of a symlink when the user doesn't
8247 have the required privileges.
8248 (get_file_security_desc_by_name): Rename from
8249 get_file_security_desc.
8250 (stat_worker): New function, with most of the guts of 'stat', and
8251 with addition of handling of symlinks and support for 'lstat'.
8252 If possible, get file's attributes and security information by
8253 handle, not by name. Produce S_IFLNK bit for symlinks, when
8254 called from 'lstat'.
8255 (stat, lstat): New functions, call 'stat_worker'.
8256 (symlink, readlink, careadlinkat): Rewritten to create and resolve
8257 symlinks when the underlying filesystem supports them.
8259 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
8261 Fix macroexp crash on Windows with debugging (Bug#12118).
8262 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
8263 checking subscripts; problem introduced with the recent
8264 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
8265 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
8266 since it's used in non-static inline functions now.
8268 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
8269 Don't assume buffer size fits in 'int'. Remove unused local.

8283 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
8284 * alloc.c (LISP_INLINE):
8285 * buffer.c (BUFFER_INLINE):
8286 * category.c (CATEGORY_INLINE):
8287 * character.c (CHARACTER_INLINE):
8288 * charset.c (CHARSET_INLINE):
8289 * composite.c (COMPOSITE_INLINE):
8290 * dispnew.c (DISPEXTERN_INLINE):
8291 * sysdep.c (SYSTIME_INLINE):
8292 Define to EXTERN_INLINE, so that the corresponding functions
8293 are compiled into code.
8294 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
8295 (INLINE_HEADER_END): New macros.
8296 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

8316 hard-coding the path separator.
8318 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
8320 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
8321 This how ASET and AREF are supposed to work, and makes
8322 it easier to think about future improvements. See
8323 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
8324 * charset.h (set_charset_attr): New function.
8325 All lvalue-style uses of CHARSET_DECODER etc. changed to use it.
8326 * lisp.h (ASET): Rewrite so as not to use AREF in an lvalue style.

8739 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
8740 enumeration constants, as PURE and HEAP are too general, and clash
8741 with other headers and sources, such as gmalloc.c and the
8742 MS-Windows system headers. All users changed.
8744 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
8746 Revert last save_excursion_save and save_excursion_restore changes.
8747 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

8760 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
8761 arms of an 'if', not using conditional expressions; otherwise GDB
8762 complains about the types in the unevaluated arm when the argument
8763 is an integer literal.
8764 (xgetint): Simplify expression.
8765 * alloc.c (gdb_make_enums_visible): New constant. This ports to
8766 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
8767 Zaretskii in <http://bugs.gnu.org/12036#13>.
8768 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
8769 needed now that we have gdb_make_enums_visible.
8770 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
8771 (enum enum_USE_LSB_TAG):
8772 New enum types, packaging up enums that need to be exported to GDB.

8814 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
8815 emacs.c, as this is a more-suitable home. Had this been done earlier
8816 the fix for 12036 would have avoided some of the problems noted in
8817 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
8818 would have been more obvious.
8819 * emacs.c: Do not include <verify.h>; no longer needed.
8820 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
8821 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
8822 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):

8827 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
8828 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
8829 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
8830 not be usable in #if. This simplifies things.
8832 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
8834 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.

8839 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
8840 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
8841 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
8842 Adjust to changes in lisp.h and emacs.c, by using
8843 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
8844 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
8845 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
8846 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
8847 instead of gdb_valbits.
8848 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
8849 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
8850 instead of gdb_array_mark_flag.
8851 (xboolvector): Get size from $->size, not $->header.size.
8852 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
8853 (xreload, hook-run, hookpost-run): Remove.
8854 * emacs.c: Include <verify.h>.
8855 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
8856 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
8858 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
8859 (gdb_USE_LSB_TAG): New enum constants.
8860 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
8861 Also define these as enum constants, so they're visible to GDB.
8862 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
8863 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
8864 as constants, so they're visible to GDB.

8867 Now enum constants, not macros, so they're visible to GDB.
8868 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
8869 more convenient now. All uses changed.
8870 (VALMASK) [USE_LSB_TAG]: Also define in this case.
8871 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
8873 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

8878 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
8880 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
8881 add argument, tune behavior, and adjust all callers.
8883 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
8885 Use typedef for EMACS_INT, EMACS_UINT.
8886 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
8887 than macros. This simplifies debugging in the usual case, since
8888 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
8889 and it allows expressions involving EMACS_INT casts.
8890 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
8892 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

8902 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
8904 Adjust buffer text indirection counters at the end of Fkill_buffer.
8905 * buffer.c (Fkill_buffer): Adjust indirection counters when the
8906 buffer is definitely dead. This should really fix an issue reported
8907 by Christoph Scholtes again. (Bug#12007).
8908 (init_buffer_once): Initialize indirection counters of
8909 buffer_defaults and buffer_local_symbols (for sanity and safety).
8911 2012-07-24 Eli Zaretskii <eliz@gnu.org>
8913 * xdisp.c (init_iterator): Don't compute dimensions of truncation
8914 and continuation glyphs on tooltip frames, leave them at zero.

8942 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
8944 Swap buffer text indirection counters in Fbuffer_swap_text.
8945 * buffer.c (Fbuffer_swap_text): Swap indirections too.
8946 This avoids crash reported by Christoph Scholtes at
8947 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
8949 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
8951 * nsmenu.m (Popdown_data): New struct.
8952 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
8954 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
8955 (initWithContentRect): Make imgView and contentView non-static
8956 and autorelease them. Also autorelease img and matrix (Bug#12005).
8957 (dealloc): Remove (Bug#12005).
8959 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
8961 Adjust consing_since_gc when objects are explicitly freed.

8974 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
8976 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
8977 as it's limited by the amount of memory, not by INT_MAX.
8979 2012-07-21 Eli Zaretskii <eliz@gnu.org>
8981 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
8982 in special-event-map. See the discussion at

9527 and continuation glyphs alike.
9528 (produce_special_glyphs) [HAVE_WINDOW_SYSTEM]: Produce a stretch
9529 glyph of a suitably computed width, to align the special glyphs at

9705 * s/aix4-2.h (unix): Remove; no longer needed.
9707 EMACS_TIME simplification (Bug#11875).
9708 This replaces macros (which typically do not work in GDB)
9709 with functions, typedefs and enums, making the code easier to debug.
9710 The functional style also makes code easier to read and maintain.
9711 * systime.h: Include <sys/time.h> on all hosts, not just if
9712 WINDOWSNT, since 'struct timeval' is needed in general.

9728 (add_emacs_time, sub_emacs_time): New functions.
9729 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.

9752 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
9753 Prefer snprintf to strncpy.
9754 * nsterm.m (ns_term_init):
9755 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
9756 * nsterm.m (ns_term_init):
9757 Avoid the need for strncpy, by using build_string or
9758 make_unibyte_string directly. Use dtoastr, not snprintf.
9759 * process.c (Fmake_network_process): Diagnose service names that
9760 are too long, rather than silently truncating them or creating
9761 non-null-terminated names.

9763 * sysdep.c (system_process_attributes) [GNU_LINUX]:
9764 Prefer sprintf to strncat.

9778 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
9779 where argument type is known to be a Lisp_Cons.

9834 O_RDONLY already includes it).
9836 Stop ns builds setting the EMACSLOADPATH environment variable.
9837 * nsterm.m (ns_load_path): Rename from ns_init_paths.
9838 Now it does not set EMACSLOADPATH, just returns the load-path string.

9840 * lread.c [HAVE_NS]: Include nsterm.h.
9841 (init_lread) [HAVE_NS]: Use ns_load_path.

9851 (ns_init_paths): Do not set EMACSPATH.

9911 Move marker debugging code under MARKER_DEBUG.
9912 * marker.c (MARKER_DEBUG): Move marker debugging code under
9913 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
9914 for bootstrap with --enable-checking (~3x slowdown reported

9947 * lread.c (load_path_check): Now static.
9949 Fix some minor --with-ns problems found by static checking.
9950 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
9951 (x_set_font) [!HAVE_X_WINDOWS]:
9952 * image.c (xpm_load_image) [HAVE_NS]:
9953 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
9954 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
9955 Remove unused local.
9956 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
9957 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
9958 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
9959 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
9960 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
9961 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
9962 Fix pointer signedness problem.
9963 * xfaces.c (FRAME_X_FONT_TABLE):
9964 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
9966 2012-07-07 Glenn Morris <rgm@gnu.org>
9968 * lread.c (load_path_check): New function, split from init_lread.
9969 (init_lread): Reorganize. Motivation:
9970 If EMACSLOADPATH is set, check/warn about that rather than the
9971 defaults, which we are not going to use. Hence we can remove
9972 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
9973 Don't warn if site-lisp directories are missing.
9974 If not installed, start from a blank load-path, since
9975 PATH_LOADSEARCH refers to the eventual installation directories.
9977 2012-07-07 Eli Zaretskii <eliz@gnu.org>
9979 Support truncation and continuation glyphs on GUI frames, when
9980 fringes are disabled. (Bug#11832)
9981 * xdisp.c (init_iterator): Get dimensions of truncation and
9982 continuation glyphs even if on GUI frames.
9983 Adjust it->last_visible_x on GUI frames when the left or right fringes,
9984 or both, are absent.
9985 (start_display, move_it_in_display_line_to): Handle the case of a
9986 GUI frame without a fringe to display continuation or truncation
9988 (insert_left_trunc_glyphs): Support GUI frames: make sure
9989 truncation glyphs overwrite enough glyphs from the current line to
9990 have sufficient space in pixels.
9991 (display_line): Support truncation and continuation glyphs on GUI
9992 frames. If some spare pixels are left on the line after inserting
9993 the truncation glyphs, fill that space with a stretch glyph of a
9994 suitably computed width.
9996 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
9997 produce_glyphs, to support GUI sessions.
9999 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
10001 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
10003 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
10005 Do not require float-time's arg to fit in time_t (Bug#11825).
10006 This works better on hosts where time_t is unsigned, and where
10007 float-time is applied to the (negative) difference between two times.
10008 * editfns.c (decode_time_components): Last arg is now double *,
10009 not int *, and means to store all the result as a double, without
10010 worrying about whether the seconds part fits in time_t.
10011 All callers changed.
10012 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
10013 All callers changed.
10014 (Ffloat_time): Do not fail merely because the specified time falls
10015 outside of time_t range.
10017 2012-07-07 Glenn Morris <rgm@gnu.org>
10019 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
10020 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
10021 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
10023 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
10025 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
10026 Update dependencies.
10028 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
10030 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
10032 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
10033 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
10034 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
10035 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
10036 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
10037 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
10039 * xfont.c (compare_font_names): Redo to omit the need for casts.
10041 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
10043 * xfns.c (Fx_change_window_property): Doc fix.
10044 * w32fns.c (Fx_change_window_property): Doc fix.
10046 * w32fns.c (Fx_window_property): Accept the same arguments as the
10047 X Windows version. Doc fix.
10048 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
10050 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
10051 Eli Zaretskii <eliz@gnu.org>
10053 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
10054 Windows-specific code from nt/config.nt moved here.
10055 Obsolete settings removed.
10057 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
10059 * process.c: Avoid unnecessary calls to gettime.
10060 (wait_reading_process_output): Don't get the time of day
10061 when gobbling data immediately and not waiting, as there's no need
10062 for it in that case. This removes a FIXME.
10064 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
10066 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
10067 is defined (Bug#11768).
10069 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10071 Fix marker debugging code.
10072 * marker.c (byte_char_debug_check): Do not perform the check
10073 if buffer is not multibyte.
10074 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
10075 Call byte_char_debug_check with correct arguments.
10077 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10079 Compile marker debugging code only if ENABLE_CHECKING is defined.
10080 * marker.c (byte_char_debug_check, count_markers):
10081 Use only if ENABLE_CHECKING is defined.
10082 (byte_debug_flag): Remove.
10083 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
10084 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
10086 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10088 Avoid code repetition in marker-related functions.
10089 * marker.c (attach_marker): New function.
10090 (Fset_marker, set_marker_restricted, set_marker_both)
10091 (set_marker_restricted_both): Use it.
10092 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
10093 Consistently rename charno to charpos.
10094 (marker_position): Add eassert.
10095 (marker_byte_position): Convert to eassert.
10097 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10099 Simplify list operations in unchain_overlay and unchain_marker.
10100 * buffer.c (unchain_overlay): Simplify. Add comment.
10101 * marker.c (unchain_marker): Simplify. Fix comments.
10103 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

10108 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
10109 * composite.c (autocmp_chars): Likewise.
10110 * editfns.c (buildmark): Remove.
10111 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
10112 (save_restriction_save): Use build_marker.
10113 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
10114 * window.c (save_window_save): Likewise.
10116 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10118 Do not use Fdelete_overlay in delete_all_overlays
10119 to avoid redundant calls to unchain_overlay.
10120 * buffer.c (drop_overlay): New function.
10121 (delete_all_overlays, Fdelete_overlay): Use it.
10122 * minibuf.c (get_minibuffer): Fix comment.
10124 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
10126 Port to OpenBSD 5.1 amd64.
10127 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
10128 This is needed for OpenBSD, and should be harmless on all BSD systems.
10129 Also, include <sys/sysctl.h>, as it should be available on all
10130 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
10131 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
10132 use p_pid member, not kp_proc.pid.
10134 2012-07-06 Glenn Morris <rgm@gnu.org>
10136 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
10138 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
10140 More xmalloc and related cleanup.
10141 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
10142 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:
10143 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, fns.c:

10149 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
10151 Omit needless casts involving void * pointers and allocation.
10152 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
10153 as the former is more robust if P's type is changed.
10154 Prefer xzalloc to xmalloc + memset 0.
10155 Simplify malloc-or-realloc to realloc.
10156 Don't worry about xmalloc returning a null pointer.
10157 Prefer xstrdup to xmalloc + strcpy.
10158 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
10160 * keyboard.c (apply_modifiers_uncached): Prefer local array to
10161 alloca of a constant.
10163 2012-07-05 Eli Zaretskii <eliz@gnu.org>
10165 * xdisp.c (display_line): Fix horizontal pixel coordinates when
10166 hscroll is larger than the line width. Fixes long and futile
10167 looping inside extend_face_to_end_of_line (on a TTY) producing
10168 glyphs that are not needed and thrown away.
10170 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
10172 * marker.c (set_marker_restricted_both): Simplify by using
10175 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
10177 * editfns.c (region_limit): Simplify by using clip_to_bounds.
10179 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
10181 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
10182 not defined (Bug#11768).
10183 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
10184 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
10185 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
10186 followed by gtk_box_set_homogeneous (Bug#11768).
10187 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
10188 (update_theme_scrollbar_width, xg_create_scroll_bar):
10189 Use gtk_scrollbar_new (Bug#11768).
10190 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
10191 (is_box_type): New function (Bug#11768).
10192 (xg_tool_item_stale_p): Call is_box_type.
10193 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
10194 with default display (Bug#11768).
10196 2012-07-05 Eli Zaretskii <eliz@gnu.org>
10198 * xdisp.c (window_hscroll_limited): New function.
10199 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
10200 coordinates when window's hscroll is set to insanely large
10201 values. (Bug#11857)
10203 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
10205 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
10206 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.

10264 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
10266 * fileio.c (time_error_value): Check the right error number.
10267 Problem reported by Troels Nielsen in
10268 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
10270 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10272 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
10273 This should be fixed in a better way; see Eli Zaretskii in
10274 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
10275 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
10277 * fileio.c (time_error_value): Rename from special_mtime.
10278 The old name's problems were noted by Eli Zaretskii in
10279 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
10281 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
10282 This variable's comment says Emacs needs at least one GDB-visible
10283 symbol of type enum pvec_type, to work around GDB problems.
10284 The symbol's value doesn't matter.
10286 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
10287 that causes compilation to fail on pre-C99 compilers.
10289 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
10291 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
10292 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
10294 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10296 * buffer.c (init_buffer_once): Fix initialization of
10297 headers for buffer_defaults and buffer_local_symbols.
10298 Reported by Juanma Barranquero <lekktu@gmail.com>.
10300 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
10302 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
10303 * lisp.h (enum pvec_type): Use fewer bits.
10304 (PSEUDOVECTOR_SIZE_BITS): New constant.
10305 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
10306 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
10307 change in pvec_type.
10308 (PSEUDOVECTOR_TYPEP): New macro.
10309 (TYPED_PSEUDOVECTORP): Use it.
10310 * fns.c (internal_equal): Adapt code to extract pvectype.
10311 * emacs.c (gdb_pvec_type): Update type.
10312 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
10313 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
10314 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
10315 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
10316 (sweep_vectors): Use it. Use local var `total_bytes' instead of
10317 abusing vector->header.next.nbytes.
10318 (live_vector_p): Use PVEC_TYPE.
10319 (mark_object): Adapt code to extract pvectype. Use switch.
10321 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10323 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
10324 Tighten new eassert a bit.
10326 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10328 Fix compilation with --enable-gcc-warnings and -O1
10329 optimization level.
10330 * doprnt.c (doprnt): Change type of tem to int, initialize
10331 to avoid compiler warning. Add eassert.
10332 * search.c (simple_search): Initialize match_byte to avoid
10333 compiler warning. Add eassert.
10335 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10337 Avoid weird behavior with large horizontal scrolls.
10338 Without this change, for example, large hscroll values would
10339 mess up Emacs's display on Fedora 15 x86, presumably due to
10340 overflows in int calculations in the display code.
10341 Also, if buffers had long lines, Emacs would freeze.
10342 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
10343 (set_window_hscroll): New function, containing the old guts of
10344 Fset_window_hscroll. Return the clipped value.
10345 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
10346 This avoids the need to check against PTRDIFF_MAX.
10348 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
10350 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10352 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
10354 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10356 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
10357 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
10358 since GCC 4.4.6 issues a bogus warning for them.
10360 Fix bugs in file timestamp newness comparisons.
10361 * fileio.c (Ffile_newer_than_file_p):
10362 * lread.c (Fload): Use full timestamp resolution of files,
10363 not just the 1-second resolution, so that files that are only
10364 slightly newer still count as newer.
10365 * fileio.c (Ffile_newer_than_file_p): Don't assume file
10366 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
10368 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
10370 * fileio.c: Improve handling of file time marker. (Bug#11852)
10371 (special_mtime): New function.
10372 (Finsert_file_contents, Fverify_visited_file_modtime):
10373 Use it to set special mtime values consistently.
10375 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
10377 * fileio.c (Finsert_file_contents): Properly handle st_mtime
10378 marker for non-existing file. (Bug#11852)
10380 2012-07-03 Glenn Morris <rgm@gnu.org>
10382 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
10383 and did not make it into globals.h).
10385 2012-07-03 Tom Tromey <tromey@redhat.com>
10387 * window.c (Fset_window_margins, Fset_window_fringes)
10388 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.

10423 2012-07-03 Glenn Morris <rgm@gnu.org>
10425 * lisp.h (Frandom): Make it visible to C.
10426 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
10427 buffer for invisible buffers. (Bug#1229)
10429 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10431 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
10432 values which aren't power of 2.
10433 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
10434 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
10437 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
10439 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
10441 * alloc.c (mark_object): Revert part of last patch to use `switch'.
10443 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10445 * alloc.c (allocate_vector_block): Remove redundant
10446 calls to mallopt if DOUG_LEA_MALLOC is defined.
10447 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
10448 avoid calls to mallopt if zero_vector is returned.
10450 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10452 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
10453 is enabled, avoid dereferencing NULL current_sblock if
10456 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10458 Cleanup basic buffer management.
10459 * buffer.h (struct buffer): Change layout to use generic vector
10460 marking code. Fix some comments. Change type of 'clip_changed'
10461 to bitfield. Remove unused #ifndef old.
10462 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
10463 (GET_OVERLAYS_AT): Fix indentation.
10464 (for_each_per_buffer_object_at): New macro.
10465 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
10466 (Fbuffer_local_variables): Use it.
10467 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
10468 * alloc.c (allocate_buffer): Adjust to match new layout of
10469 struct buffer. Fix comment.
10470 (mark_overlay): New function.
10471 (mark_buffer): Use it. Use mark_vectorlike to mark normal
10472 Lisp area of struct buffer.
10473 (mark_object): Use it. Adjust marking of misc objects
10474 and related comments.
10476 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
10478 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
10479 wrapper that is not needed because the wrapped code is a no-op (zero
10480 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
10481 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
10483 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
10485 * alloc.c (mark_buffer): Simplify. Remove prototype.
10486 (mark_object): Add comment. Reorganize marking of vector-like
10487 objects. Use CHECK_LIVE for all vector-like objects except buffers
10488 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
10489 Avoid redundant calls to mark_vectorlike for bool vectors.
10491 2012-06-30 Glenn Morris <rgm@gnu.org>
10493 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
10495 * epaths.in (PATH_SITELOADSEARCH): New.
10496 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
10497 This is rather than relying on --enable-locallisppath elements
10498 having "site-lisp" in their names. (Bug#10208#25, 11658)
10500 2012-06-30 Eli Zaretskii <eliz@gnu.org>
10502 * w32proc.c (sys_select): Accept and ignore one more argument.
10504 * w32.c (emacs_gnutls_pull): Call select with one more argument.
10506 * sysselect.h [DOS_NT]: Don't include sys/select.h.
10507 (pselect) [!MS_DOS]: Redirect to sys_select.
10509 * sysdep.c: Don't include dos.h and dosfns.h.
10511 * process.c (sys_select):
10512 * msdos.c (sys_select): Accept one more argument and ignore it.
10514 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
10515 adapt data types and code to that.
10518 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
10519 which clashes with the gnulib function of the same name.
10521 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
10523 * font.c (font_style_to_value, font_style_symbolic)
10524 (font_prop_validate_style): Add type checks for values in
10527 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
10529 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
10532 2012-06-29 Eli Zaretskii <eliz@gnu.org>
10534 * xdisp.c (try_window_id): Undo last change.
10536 * w32.c (getwd): Adjust commentary about startup_dir.
10537 (init_environment): Always call sys_access, even in non-MSVC
10538 builds. Don't chdir to the directory of the Emacs executable.
10539 This undoes code from 1997 which was justified by the need to
10540 "avoid conflicts when removing and renaming directories". But its
10541 downside was that every relative file name was being interpreted
10542 relative to the directory of the Emacs executable, which can never
10543 be TRT. In particular, it broke sys_access when called with
10544 relative file names.
10545 (sys_access): Map GetLastError to errno.
10547 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>

10551 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
10553 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
10556 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
10558 * gnutls.c (emacs_gnutls_handshake):
10559 Add QUIT to make the loop interruptible.
10561 2012-06-29 Glenn Morris <rgm@gnu.org>
10563 * charset.c (init_charset): Make lack of etc/charsets fatal.
10565 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>

10569 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
10571 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
10572 undefined. Convert from xassert to eassert.
10573 * nsmenu.m: Convert from xassert to eassert.
10574 * nsterm.m: Likewise.
10576 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>

10580 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
10582 Avoid integer overflow on scroll-left and scroll-right.
10583 * window.c (HSCROLL_MAX): New macro.
10584 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
10585 overflow when requested scroll falls outside ptrdiff_t range.
10587 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
10589 * window.h (struct window): Change type of 'hscroll',
10590 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
10591 'last_modified' and 'last_overlay_modified' to EMACS_INT.
10592 Adjust users accordingly.
10593 * xdisp.c (try_cursor_movement): Replace type check with eassert.
10594 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
10595 from EMACS_INT to ptrdiff_t.
10596 (make_window): Omit redundant initialization.

10615 Fix GLYPH_DEBUG usage assuming that it may be undefined,
10616 adjust comments accordingly.

10698 when building with Clang.

10737 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
10739 Use sprintf return value instead of invoking strlen on result.
10740 In the old days this wasn't portable, since some sprintf
10741 implementations returned char *. But they died out years ago and
10742 Emacs already assumes sprintf returns int.
10743 Similarly for float_to_string.
10744 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

10750 * xdisp.c (message_dolog):
10751 * xfns.c (syms_of_xfns):
10752 Use sprintf or float_to_string result to avoid need to call strlen.
10753 * data.c (Fnumber_to_string):
10754 Use make_unibyte_string, since the string must be ASCII.
10755 * lisp.h, print.c (float_to_string): Now returns int length.
10756 * term.c (produce_glyphless_glyph):
10757 Use sprintf result rather than recomputing it.
10759 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
10760 * Makefile.in (ALL_CFLAGS):
10761 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

10767 strcasecmp if available.

10788 * xfns.c (x_window): Remove redundant cast.
10790 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
10792 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
10793 `const char *' to `char *' to avoid compiler warning.
10795 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
10797 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
10798 instead of truncating it to 63 (admittedly a generous limit).
10800 * process.c: Fix spelling and caps in comments.
10802 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
10804 * emacs.c (setpgrp): Remove definition, unused.

10851 Remove unnecessary forward decls.
10853 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
10855 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).

10857 * dispnew.c (Fsleep_for, sit_for):
10858 * keyboard.c (kbd_buffer_get_event):

10860 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
10861 This improves on the previous patch, which introduced a bug
10862 when time_t is unsigned and as wide as intmax_t.
10863 See <http://bugs.gnu.org/9000#51>.

10894 language ID in the event parameters.
10896 * w32term.c (w32_read_socket): Put the new keyboard codepage into
10897 event.code, not the obscure "character set ID".
10899 2012-06-23 Chong Yidong <cyd@gnu.org>
10901 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.

10928 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
10930 Support higher-resolution time stamps (Bug#9000).
10931 The time stamps are only nanosecond-resolution at the C level,
10932 since that's the best that any real-world system supports now.
10933 But they are picosecond-resolution at the Lisp level, as that's
10934 easy, and leaves room for future OS improvements.
10936 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
10939 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
10940 Don't get current time unless it's needed.
10942 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
10943 now provides it if it's absent.
10944 (start_atimer): Port to higher-res time stamps.
10945 Check for time stamp overflow. Don't get current time more
10946 often than is needed.
10948 * buffer.h (struct buffer): Buffer modtime now has high resolution.
10949 Include systime.h, not time.h.
10950 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
10952 * dired.c: Include stat-time.h.
10953 (Ffile-attributes): File times now have higher resolution.
10955 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
10956 (struct image): Timestamp now has higher resolution.
10958 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
10959 has at least microseconds now. All uses removed.
10960 (update_frame, update_single_window, update_window, update_frame_1)
10961 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
10962 (duration_to_sec_usec): Remove; no longer needed.
10964 * editfns.c (time_overflow): Now extern.
10965 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)

10970 (decode_time_components, lisp_seconds_argument): New functions.
10971 (make_time): Now static.
10972 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
10973 Report an error if the time is invalid, rather than having the caller
10976 * fileio.c: Include <stat-time.h>
10977 (Fcopy_file): Copy higher-resolution time stamps.
10978 Prefer to set the time stamp via a file descriptor if that works.
10979 (Fset_file_times, Finsert_file_contents, Fwrite_region)
10980 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
10981 (Fvisited_file_modtime, Fset_visited_file_modtime):
10982 Support higher-resolution time stamps.
10984 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
10986 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
10988 * image.c (prepare_image_for_display, clear_image_cache)
10989 (lookup_image): Port to higer-resolution time stamps.
10991 * keyboard.c (start_polling, bind_polling_period):
10992 Check for time stamp overflow.
10993 (read_char, kbd_buffer_get_event, timer_start_idle)
10994 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
10995 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
10996 Port to higher-resolution time stamps. Do not assume time_t is signed.
10997 (decode_timer): New function. Timers are now vectors of length 9,
10998 not 8, to accommodate the picosecond component.
10999 (timer_check_2): Use it.
11001 * nsterm.m (select_timeout, timeval_subtract): Remove.
11002 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
11003 as they're a bit more accurate and handle overflow better.
11004 (ns_select): Change prototype to be compatible with pselect.
11005 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
11006 * nsterm.h (ns_select): Adjust prototype.
11008 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
11009 us-resolution time stamps.
11010 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
11012 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
11014 * lisp.h (time_overflow): New decl.
11015 (wait_reading_process_output): First arg is now intmax_t, not int,
11016 to accommodate larger waits.
11018 * process.h (struct Lisp_Process.read_output_delay):
11019 Now counts nanoseconds, not microseconds.
11020 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
11022 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
11023 (wait_reading_process_output):
11024 Port to ns-resolution time stamps.
11025 (Faccept_process_output, wait_reading_process_output):
11026 Check for time stamp overflow. Do not assume time_t is signed.
11027 (select_wrapper): Remove; we now use pselect.
11028 (Fprocess_attributes): Now generates ns-resolution time stamps.
11030 * sysdep.c: Include utimens.h. Don't include utime.h
11031 or worry about struct utimbuf; gnulib does that for us now.
11032 (gettimeofday): Remove; gnulib provides a substitute.
11033 (make_timeval): New function.
11034 (set_file_times): Now sets ns-resolution time stamps.
11035 New arg FD; all uses changed.
11036 (time_from_jiffies, ltime_from_jiffies, get_up_time)
11037 (system_process_attributes):
11038 Now returns ns-resolution time stamp. All uses changed.
11039 Check for time stamp overflow.
11041 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
11042 provides a substitute now.
11044 * systime.h: Include timespec.h rather than sys/time.h and time.h,
11045 since it guarantees struct timespec.
11046 (EMACS_TIME): Now struct timespec, so that we can support
11047 ns-resolution time stamps.
11048 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
11049 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
11050 (EMACS_USECS): Remove.
11051 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
11052 so multiply the arg by 1000 before storing it.
11053 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
11055 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
11056 Port to ns-resolution time stamps.
11057 (EMACS_TIME_NEG_P): Remove; replaced by....

11062 (make_timeval, make_lisp_time, decode_time_components): New decls.
11063 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
11064 that it mishandled time_t overflow. You can't compare by subtracting!
11065 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
11066 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
11068 * term.c: Include <sys/time.h>.
11069 (timeval_to_Time): New function, for proper overflow wraparound.
11070 (term_mouse_position, term_mouse_click): Use it.
11072 * undo.c (record_first_change): Support higher-resolution time stamps
11073 in the undo buffer.
11074 (Fprimitive_undo): Use them when restoring time stamps.
11076 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
11077 (w32_get_internal_run_time):
11078 Port to higher-resolution Emacs time stamps.
11079 (ltime): Now accepts single 64-bit integer, as that's more convenient
11082 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
11084 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
11085 for compatibility with pselect. Support ns-resolution time stamps.
11087 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
11089 * xselect.c (wait_for_property_change, x_get_foreign_selection):
11090 Check for time stamp overflow, and support ns-resolution time stamps.
11092 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
11093 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
11094 (timeval_subtract): Remove; no longer needed.
11095 (XTflash, XTring_bell, x_wait_for_event):
11096 Port to ns-resolution time stamps. Don't assume time_t is signed.

11102 2012-06-22 Eli Zaretskii <eliz@gnu.org>
11104 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
11105 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
11106 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
11107 staticidx goes up to 1597 out of 1600 = 0x640.)
11109 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
11111 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.

11123 access to `contents' member of Lisp_Vector objects with AREF and ASET
11126 2012-06-19 Chong Yidong <cyd@gnu.org>
11128 * frame.c (delete_frame): When selecting a frame on a different
11129 text terminal, do not alter the terminal's top-frame.

11132 frame's selected window and its terminal's top-frame.
11133 (unwind_format_mode_line): Restore them.
11134 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
11136 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
11137 since tty frames can be explicitly named.
11138 (prepare_menu_bars): Likewise.
11140 * term.c (Ftty_top_frame): New function.
11142 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

11145 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
11146 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
11147 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in

11157 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
11158 gets killed during executing of this function (Bug#11665).
11159 Try to always return Qt when the buffer has been actually killed.
11160 (Vkill_buffer_query_functions): In doc-string say that functions
11161 run by this hook should not change the current buffer.
11163 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
11165 Fix recently-introduced process.c problems found by static checking.
11166 * process.c (write_queue_push, write_queue_pop, send_process):
11167 Use ptrdiff_t, not int or EMACS_INT, for buffer lengths and offsets.
11168 (write_queue_pop): Fix pointer signedness problem.
11169 (send_process): Remove unused local.
11171 2012-06-17 Chong Yidong <cyd@gnu.org>

11185 * lisp.h (eassert): Assume C89 or later.
11186 This removes the need for CHECK.
11187 (CHECK): Remove. Its comments about always evaluating its
11188 argument were confusing, as 'eassert' typically does not evaluate
11191 * coding.c (produce_chars): Use ptrdiff_t, not int.
11193 * xterm.c (x_draw_underwave): Check for integer overflow.
11194 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

11367 USE_LISP_UNION_TYPE + USE_LSB_TAG cleanup (Bug#11604)
11368 * alloc.c (make_number) [!defined make_number]:
11369 Remove, as lisp.h always defines this now.
11370 (mark_maybe_pointer): Simplify since USE_LSB_TAG is always defined now.
11371 (roundup_size): Verify that it is a power of 2.
11372 * data.c (Fmake_variable_buffer_local, Fmake_local_variable):

11376 USE_LSB_TAG now is always defined to be either 0 or 1.
11378 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
11379 code works fine either way, and efficiency is not a concern here,
11380 as the union type is for debugging, not for production.
11381 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
11382 Use an inline function on all platforms when using the union type,
11383 since this is simpler and 'static inline' can be used portably

11386 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
11387 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.

11455 * dbusbind.c (XD_BASIC_DBUS_TYPE): Use dbus_type_is_valid and
11456 dbus_type_is_basic if available.
11457 (xd_extract_signed, xd_extract_unsigned): Rename from
11458 extract_signed and extract_unsigned, respectively. Adapt callers.

11471 would generate the diagnostic "Making \302\247 buffer-local while
11474 2012-06-08 Eli Zaretskii <eliz@gnu.org>
11476 * dispnew.c (showing_window_margins_p): Undo last change, which

11489 * dispnew.c (showing_window_margins_p): Wrap in #if 0 to prevent unused
11490 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
11492 2012-06-08 Eli Zaretskii <eliz@gnu.org>
11494 * alloc.c (allocate_vectorlike): Fix last change.
11496 2012-06-08 Dmitry Antipov <dmantipov@yandex.ru>
11498 Block-based vector allocation of small vectors.

11500 adjust comment accordingly.
11501 * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'
11502 to denote vector blocks. Adjust users (live_vector_p,

11525 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
11527 * doprnt.c (doprnt): Truncate multibyte char correctly.
11528 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
11529 would mishandle a string argument "Xc" if X was a multibyte
11530 character of length 2: it would truncate after X's first byte
11531 rather than including all of X.
11533 2012-06-06 Chong Yidong <cyd@gnu.org>
11535 * buffer.c (word_wrap): Doc fix.
11537 2012-06-04 Paul Eggert <eggert@cs.ucla.edu>

11582 * minibuf.c (Fassoc_string): Remove duplicate declaration.
11584 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
11585 Convert pctcpu and pctmem to Lisp float properly.
11586 Let the compiler fold better, as 100.0/0x8000 is exact.
11588 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
11590 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
11593 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>

11600 bitfields where appropriate, remove unused fields.
11601 * window.h (struct window): Remove unused 'last_mark_x' and
11602 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
11603 change its type from Lisp_Object to bitfield.
11604 Change type of 'force_start', 'optional_new_start',
11605 'last_had_star', 'update_mode_line' and 'start_at_line_beg'

11610 Pacify gcc -Wdouble-precision when using Xaw.
11611 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
11612 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
11613 Use 'float' consistently, rather than 'float' in most places
11614 and 'double' in a couple of places.
11616 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11618 * xdisp.c (handle_stop): Detect whether we have overlay strings
11619 loaded by testing it->current.overlay_string_index to be
11620 non-negative, instead of checking whether n_overlay_strings is
11621 positive. (Bug#11587)
11623 2012-05-31 Chong Yidong <cyd@gnu.org>
11625 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

11631 * search.c (search_buffer): Remove calls to
11632 r_alloc_inhibit_buffer_relocation, as it is now called by
11633 maybe_unify_char, which was the cause of relocation of buffer text
11636 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11638 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
11639 for the duration of call to load_charset, to avoid problems with
11640 callers of maybe_unify_char that access buffer text through C
11643 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
11644 decrement the inhibition flag, instead of just setting or
11647 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
11649 Remove obsolete '#define static' cruft.
11650 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
11651 This #undef was "temporary" in 2000; it is no longer needed
11652 now that '#define static' has gone away.
11653 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
11654 (gray_bitmap_bits): Remove; no longer needed.
11655 All uses replaced with definiens.

11667 (safe_bcopy): Remove decl; no longer has that name.
11668 (main): Coalesce #if into single bit of code, for simplicity.
11669 Cast pointers to uintptr_t, since standard libraries want integers

11698 Do not create empty overlays with the evaporate property (Bug#9642).
11699 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
11700 Bug#9642, but explicitly check that the buffer the overlay would
11701 be moved to is live and rearrange lines to make sure that errors
11702 will not put the overlay in an inconsistent state.
11703 (Fdelete_overlay): Cosmetics.
11705 2012-05-28 Eli Zaretskii <eliz@gnu.org>
11707 * w32term.c (my_bring_window_to_top): New function.

11722 This avoids undefined behavior that might cause the eassert
11723 to not catch an out-of-range value.
11725 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
11727 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

11742 Only r_alloc_inhibit_buffer_relocation needed to be added;
11743 the others were already declared.
11745 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
11746 before checking whether it's out of range. Put the check inside
11748 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.

11761 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
11762 they are now on lisp.h.
11764 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
11766 * search.c (search_buffer): Use it to inhibit relocation of buffer
11767 text while re_search_2 is doing its job, because re_search_2 is
11768 passed C pointers to buffer text. (Bug#11519)
11770 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
11771 Update value to 24.
11773 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
11774 state after an additional call to move_it_in_display_line_to, keep
11775 the values of it->max_ascent and it->max_descent found for the
11777 (pos_visible_p): Revert the comparison against bottom_y to what it
11778 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
11781 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
11783 Fix coding-related core dumps with gcc -ftrapv.
11784 The code was computing A - B, where A and B are pointers, and B is
11785 random garbage. This can lead to core dumps on platforms that
11786 have special pointer registers, and it also leads to core dumps on
11787 x86-64 when compiled with gcc -ftrapv. The fix is to compute
11788 A - B only when B is initialized properly.
11789 * coding.c (coding_set_source, coding_set_destination): Return void.
11790 (coding_change_source, coding_change_destinations): New functions,
11791 with the old behaviors of coding_set_source and coding_set_destination.
11792 All callers that need an offset changed to use these new functions.
11794 2012-05-26 Glenn Morris <rgm@gnu.org>

11809 * w32inevt.c: Include termchar.h and window.h.
11810 (do_mouse_event): Support mouse-autoselect-window. When the mouse
11811 moves, call note_mouse_highlight. If help_echo changed, call
11812 gen_help_event to produce help-echo message in the echo area.
11813 Call clear_mouse_face if mouse_face_hidden is set in the mouse
11816 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
11818 * lread.c (read1): Simplify slightly to avoid an overflow warning
11819 with GCC 4.7.0 on x86-64.
11821 2012-05-26 Eli Zaretskii <eliz@gnu.org>
11823 * bidi.c (bidi_mirror_char): Revert last change: an int is
11824 definitely wide enough here.
11826 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>

11844 int might not be wide enough.

11860 (Foverlay_recenter, last_overlay_modification_hooks_used)
11861 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
11862 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11863 (validate_region): Omit unnecessary test for b <= e,
11864 since that's guaranteed by the previous test.
11865 (adjust_overlays_for_delete): Avoid pos + length overflow.
11866 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
11867 (report_overlay_modification):
11868 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11869 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
11870 Omit pointer cast, which isn't needed anyway, and doesn't work
11871 after the EMACS_INT -> ptrdiff_t change.
11872 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
11873 * buffer.h: Adjust decls to match defn changes elsewhere.

11877 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
11878 not int, to avoid needless 32-bit limit on 64-bit hosts.
11879 (exec_byte_code): Use tighter memory-full test, one that checks
11880 for alloca overflow. Don't compute the address of the object just
11881 before an array, as that's not portable. Use EMACS_INT, not
11882 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
11883 * callint.c (Fcall_interactively):
11884 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11885 * callproc.c (call_process_kill, Fcall_process):
11886 Don't assume pid_t fits into an Emacs fixnum.

11896 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11897 (casify_object): Avoid integer overflow when overallocating buffer.
11898 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
11899 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
11900 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
11901 * category.h (CATEGORYP): Don't assume arg is nonnegative.
11902 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
11903 integers are now checked earlier. All uses replaced with XINT.
11905 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11906 For CCL_MapSingle, check that content and value are in int range.

11908 Check that Vcode_version_map_vector is a vector.
11909 (resolve_symbol_ccl_program): Check that vector header is in range.
11910 Always copy the vector, so that we can check its contents reliably
11911 now rather than having to recheck each instruction as it's being
11912 executed. Check that vector words fit in 'int'.
11913 (ccl_get_compiled_code, Fregister_ccl_program)
11914 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
11915 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
11916 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
11917 contents are in range.
11918 (Fccl_execute_on_string): Check that status is in range.
11919 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
11920 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
11921 Accept and return EMACS_INT, not int, because callers can pass values
11922 out of 'int' range.

11928 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11929 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
11930 avoid mishandling large integers.
11931 * character.h: Adjust decls to match defn changes elsewhere.
11932 * charset.c (load_charset_map_from_file, find_charsets_in_text)

11939 Remove now-unnecessary CHECK_NATNUMs.
11940 (Fdefine_charset_internal): Check ranges here, more carefully.
11941 Don't rely on undefined behavior with signed left shift overflow.
11942 Don't assume unsigned int fits into fixnum, or that fixnum fits
11943 into unsigned int. Don't require max_code to be a valid fixnum;
11944 that's not true for gb10830 4-byte on a 32-bit host. Allow
11945 invalid_code to be a cons, for the same reason. Require code_offset
11946 to be a character. Avoid int overflow if max_char is close
11948 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
11949 this is intended anyway and avoids some undefined behavior.
11950 (load_charset_map): Pass unsigned, not int, as 2nd arg of
11951 INDEX_TO_CODE_POINT, as that's what it expects.
11952 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
11953 * charset.h (DECODE_CHAR): Return int, not unsigned;
11954 this is what was intended anyway, and it avoids undefined behavior.
11955 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
11956 integer-overflow issues.
11957 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
11958 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
11959 where the argument is EMACS_INT, and this behavior is not intended.
11960 * chartab.c (Fmake_char_table, Fset_char_table_range)
11961 (uniprop_get_decoder, uniprop_get_encoder):
11962 Don't assume fixnum fits in int.
11963 * cmds.c (move_point): New function, that does the gist of
11964 Fforward_char and Fbackward_char, but does so while checking
11965 for integer overflow more accurately.
11966 (Fforward_char, Fbackward_char): Use it.
11967 (Fforward_line, Fend_of_line, internal_self_insert)
11968 (internal_self_insert):
11969 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

12028 * data.c (let_shadows_buffer_binding_p, let_shadows_global_binding_p):
12029 Do not attempt to compute the address of the object just before a

12744 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).

12750 2012-05-14 Glenn Morris <rgm@gnu.org>

12757 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.

12760 (report_error, report_error_1, make_hdr, copy_sym)
12761 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
12762 Make arguments const char *, not char *, to avoid violations of C
12763 standard and to fix some AIX warnings reported by Gilles Pion.
12765 2012-05-14 Eli Zaretskii <eliz@gnu.org>
12767 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
12768 already have overlays loaded.
12769 (handle_single_display_spec): Before returning without displaying
12770 fringe bitmap, synchronize the bidi iterator with the main display
12771 iterator, by calling iterate_out_of_display_property.
12772 (iterate_out_of_display_property): Detect buffer iteration by
12773 testing that it->string is a Lisp string.
12774 (get_next_display_element): When the current object is exhausted,
12775 and there's something on it->stack, call set_iterator_to_next to
12776 proceed with what's on the stack, instead of returning zero.
12777 (set_iterator_to_next): If called at the end of a Lisp string,
12778 proceed to consider_string_end without incrementing string
12779 position. Don't increment display vector index past the end of
12780 the display vector. (Bug#11417)
12781 (pos_visible_p): Don't report a position visible when move_it_to
12782 stopped at the last line of window, which happens to be scanned
12783 backwards by the bidi iteration. (Bug#11464)
12785 2012-05-14 Eli Zaretskii <eliz@gnu.org>
12787 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
12788 and right-margin display specs even if the spec is invalid or we
12789 are on a TTY, and thus unable to display on the fringes.
12790 That's because the text with the property will not be displayed anyway,
12791 so we need to signal to the caller that this is a "replacing"
12792 display spec. This fixes display when the spec is invalid or we
12795 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
12797 * unexaix.c (make_hdr): Fix typo in prototype.
12798 This bug broke the build on AIX. Problem reported by Gilles Pion.

12802 * keyboard.c (kbd_buffer_get_event): Read special events also in

12813 2012-05-12 Glenn Morris <rgm@gnu.org>
12815 * Makefile.in (MKDIR_P): New, set by configure.
12816 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.

12827 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
12828 Update dependencies.
12830 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
12832 * xgselect.c (xg_select): Put maxfds+1 into a var.
12833 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
12835 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
12837 2012-05-10 Dave Abrahams <dave@boostpro.com>
12839 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
12840 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
12842 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
12844 * dbusbind.c (xd_registered_buses): New internal Lisp object.
12845 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
12846 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
12847 Initialize xd_registered_buses.
12849 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
12851 Untag more efficiently if USE_LSB_TAG.
12852 This is based on a proposal by YAMAMOTO Mitsuharu in
12853 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
12854 For an admittedly artificial (nth 8000 longlist) benchmark on
12855 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
12856 Emacs's overall text size by 1%.
12857 * lisp.h (XUNTAG): New macro.
12858 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
12859 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
12860 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
12861 * eval.c (Fautoload):
12862 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
12863 * frame.h (XFRAME): Use XUNTAG.
12865 Port recent dbusbind.c changes to 32-bit --with-wide-int.
12866 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
12867 Remove unportable assumptions about print widths of types like
12869 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
12870 intptr_t when converting between pointer and integer, to avoid GCC
12871 warnings about wrong width.
12873 2012-05-09 Eli Zaretskii <eliz@gnu.org>
12875 * w32proc.c (new_child): Force Windows to reserve only 64KB of
12876 stack for each reader_thread, instead of defaulting to 8MB
12877 determined by the linker. This avoids failures in creating
12878 subprocesses on Windows 7, see the discussion in this thread:
12879 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
12881 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
12883 Fix up display of the *Minibuf-0* buffer in the mini window.
12884 * keyboard.c (read_char): Don't clear the echo area if there's no
12886 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
12887 contents of *Minibuf-0*) if there's no message displayed in its stead.
12889 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
12891 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
12894 2012-05-06 Chong Yidong <cyd@gnu.org>
12896 * lisp.mk (lisp): Update.
12898 2012-05-05 Jim Meyering <meyering@redhat.com>
12900 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
12902 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
12904 * data.c (PUT_ERROR): New macro.
12905 (syms_of_data): Use it. Add new error type `user-error'.
12906 * undo.c (user_error): New function.
12907 (Fprimitive_undo): Use it.
12908 * print.c (print_error_message): Adjust print style for `user-error'.
12909 * keyboard.c (user_error): New function.
12910 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
12912 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
12914 Do not limit current-time-string to years 1000..9999.
12915 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
12916 (Fcurrent_time_string): Support any year that is supported by the
12917 underlying localtime representation. Don't use asctime, as it
12918 has undefined behavior for years outside the range -999..9999.
12920 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
12922 Fix race conditions involving setenv, gmtime, localtime, asctime.
12923 Without this fix, interrupts could mess up code that uses these
12924 nonreentrant functions, since setting TZ invalidates existing
12925 tm_zone or tzname values, and since most of these functions return
12926 pointers to static storage.
12927 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
12928 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
12929 Grow the critical sections to include not just invoking
12930 localtime/gmtime, but also accessing these functions' results
12931 including their tm_zone values if any, and any related TZ setting.
12932 (format_time_string): Last arg is now struct tm *, not struct tm **,
12933 so that the struct tm is saved in the critical section.
12934 All callers changed. Simplify allocation of initial buffer, partly
12935 motivated by the fact that memory allocation needs to be outside
12936 the critical section.
12938 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
12940 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
12941 with RESET_INTERVAL.
12943 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
12944 Remove duplicated buffer name initialization.
12946 2012-05-02 Jim Meyering <jim@meyering.net>
12948 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
12950 * xfns.c (x_window): Use xstrdup (Bug#11375).
12952 2012-05-02 Eli Zaretskii <eliz@gnu.org>
12954 * xdisp.c (pos_visible_p): If already at a newline from the
12955 display string before the 'while' loop, don't walk back the glyphs
12956 from it3.glyph_row. Solves assertion violation when the display
12957 string begins with a newline (egg.el). (Bug#11367)
12959 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
12961 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
12964 2012-05-01 Glenn Morris <rgm@gnu.org>
12966 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
12967 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
12968 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
12969 All were removed before 23.1.
12971 * dispnew.c: Remove HAVE_LIBNCURSES test;
12972 it is always true on relevant platforms.
12974 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
12975 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
12977 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
12979 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
12981 * .gdbinit (xpr): Remove checks for no longer existing misc types.
12982 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
12985 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
12987 Do not avoid creating empty evaporating overlays (Bug#9642).
12988 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
12989 That is, do not delete an evaporating overlay if it becomes
12990 empty after its bounds are adjusted to fit within its buffer.
12991 This fix caused other problems, and I'm reverting it until we get
12992 to the bottom of them.
12994 2012-04-27 Chong Yidong <cyd@gnu.org>
12996 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
12998 2012-04-27 Eli Zaretskii <eliz@gnu.org>
13000 * xdisp.c (pos_visible_p): If the window start position is beyond
13001 ZV, start the display from buffer beginning. Prevents assertion
13002 violation in init_iterator when the minibuffer window is scrolled
13003 via the scroll bar.
13005 * window.c (window_scroll_pixel_based): Likewise.
13007 2012-04-27 Chong Yidong <cyd@gnu.org>
13009 * keymap.c (where_is_internal): Doc fix (Bug#10872).
13011 2012-04-27 Glenn Morris <rgm@gnu.org>
13013 * fileio.c (Fcopy_file, Fset_file_selinux_context):
13014 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
13016 2012-04-27 Eli Zaretskii <eliz@gnu.org>
13018 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
13019 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
13021 2012-04-26 Eli Zaretskii <eliz@gnu.org>
13023 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
13024 display element, check also the underlying string or buffer
13025 character. (Bug#11341)
13027 * w32menu.c: Include w32heap.h.
13028 (add_menu_item): If the call to AppendMenuW (via
13029 unicode_append_menu) fails, disable Unicode menus only if we are
13030 running on Windows 9X/Me.
13032 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
13034 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
13035 (xgetint): Add missing shift for LSB tags.
13037 2012-04-24 Martin Rudalics <rudalics@gmx.at>
13039 * keyboard.c (read_char): Don't wipe echo area for select window
13040 events: These might get delayed via `mouse-autoselect-window'
13043 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
13045 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
13046 manipulation of :loaded-from data.
13048 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
13050 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
13051 now a cons (bug#11311).
13053 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
13055 Do not create empty overlays with the evaporate property (Bug#9642).
13056 * buffer.c (Fmove_overlay): Delete an evaporating overlay
13057 if it becomes empty after its bounds are adjusted to fit within
13058 its buffer. Without this fix, in a nonempty buffer (let ((o
13059 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
13060 yields an empty overlay that has the evaporate property, which is
13061 not supposed to happen.
13063 Fix minor GTK3 problems found by static checking.
13064 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)

13069 (emacs_fixed_class_init): Omit unused local.
13070 (emacs_fixed_child_type): Remove; unused.

13072 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
13073 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
13074 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
13075 (EMACS_FIXED_GET_CLASS): Remove; unused.
13076 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
13078 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
13079 Problem reported by Juanma Barranquero for Windows -Wunused-function.
13081 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
13083 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
13084 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
13085 (__malloc_size_t, __malloc_ptrdiff_t):
13086 Remove. All uses removed, replaced by the definiens if needed,
13087 since we can assume C89 or better now.
13088 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
13089 (protect_malloc_state, align, get_contiguous_space)

13096 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
13097 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
13098 Define using prototypes, not old style.
13099 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
13100 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.

13105 Omit no-longer-needed casts.
13106 (valloc): Use getpagesize, not __getpagesize.
13107 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
13108 (struct hdr): The 'magic' member is now size_t, not unsigned long.

13163 * alloc.c: Handle unusual debugging option combinations.
13164 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
13165 since the two debugging options are incompatible.
13166 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
13168 (mem_init, mem_insert, mem_insert_fixup):
13169 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

13179 (list_system_processes, system_process_attributes) [__FreeBSD__]:
13180 Use Emacs indenting style more consistently. Avoid some casts.

13220 row, return zero immediately.
13221 (try_cursor_movement): If inside continuation line, don't back up
13222 farther than the first row after the header line, if any.
13223 Don't consider the header-line row as "partially visible", even if
13224 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)

13262 New extern decls, to avoid calling undeclared functions.
13263 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
13264 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
13265 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
13266 (NEED_MEM_INSERT): New macro.
13267 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
13268 Remove one incorrect comment and fix another.

13282 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
13283 Remove decls. This fixes an "It stinks!".
13285 * alloc.c (which_symbols): Fix alignment issue / type clash.
13287 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
13289 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
13290 (struct Lisp_Misc_Any): Likewise.
13291 (struct Lisp_Free): Likewise.
13292 * alloc.c (union aligned_Lisp_Symbol): Define.

13300 2012-04-14 Paul Eggert <eggert@cs.ucla.edu>
13302 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
13303 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
13304 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
13305 * s/netbsd.h, s/sol2-6.h:
13306 Remove definition of GC_MARK_STACK, since the default now works.
13307 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
13308 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
13309 no longer the default.
13310 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
13312 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
13314 * lread.c (lisp_file_lexically_bound_p):
13315 Fix hang at ";-*-\n" (bug#11238).
13317 2012-04-14 Eli Zaretskii <eliz@gnu.org>
13319 * xdisp.c (find_last_unchanged_at_beg_row): Don't consider a row
13320 "unchanged" if its end.pos is beyond ZV. (Bug#11199)

13329 * s/cygwin.h (PTY_OPEN): Don't try to close a bogus file descriptor.
13331 2012-04-13 Reuben Thomas <rrt@sc3d.org>
13333 * indent.c (Fmove_to_column): Change interactive spec (Bug#739).
13335 2012-04-11 Daniel Colascione <dancol@dancol.org>
13337 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
13338 against is gone. It's better to use vfork now so that when Cygwin
13339 gains a new, working vfork, we use it automatically (bug#10398).
13341 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

13357 (handle_interrupt): Use it.
13359 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
13361 * w32.c (w32_delayed_load): Record the full path of the library
13362 being loaded (bug#10424).
13364 2012-04-09 Glenn Morris <rgm@gnu.org>
13366 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
13367 not just in the obarray, before snarfing them. (Bug#11036)
13369 * Makefile.in ($(leimdir)/leim-list.el):
13370 Pass EMACS rather than BUILT_EMACS.
13372 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
13374 * process.c (make_process):
13375 * process.h: Add integer `gnutls_handshakes_tried' member to

13381 * gnutls.c (gnutls_log_function2i): Convenience log function.
13382 (emacs_gnutls_read): Use new log functions,
13383 `gnutls_handshakes_tried' process member, and
13384 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
13385 attempts per process (connection).
13387 2012-04-09 Chong Yidong <cyd@gnu.org>
13389 * eval.c (Fuser_variable_p, user_variable_p_eh)
13390 (lisp_indirect_variable): Functions deleted.
13391 (Fdefvar): Caller changed.
13393 * callint.c (Finteractive, Fcall_interactively):
13394 * minibuf.c (Fread_variable): Callers changed.
13396 2012-04-09 Eli Zaretskii <eliz@gnu.org>
13398 * xdisp.c (set_cursor_from_row): If the display string appears in
13399 the buffer at position that is closer to point than the position
13400 after the display string, display the cursor on the first glyph of
13401 the display string. Fixes cursor display when a 'display' text
13402 property immediately follows invisible text. (Bug#11094)
13404 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
13406 composite.c: use 'double' consistently
13407 * composite.c (get_composition_id): Use 'double' consistently
13408 instead of converting 'float' to 'double' and vice versa; this is
13409 easier to understand and avoids a GCC warning.
13411 2012-04-09 Glenn Morris <rgm@gnu.org>
13413 * Makefile.in: Generate leim-list with bootstrap-emacs, in
13414 preparation for dumping it with emacs. (Bug#4789)
13415 (leimdir): New variable.
13416 ($(leimdir)/leim-list.el): New rule.
13417 (emacs$(EXEEXT)): Depend on leim-list.el.

13420 (Fget_buffer_create): Don't call Qucs_set_table_for_input.
13421 (init_buffer_once, syms_of_buffer): Remove Qucs_set_table_for_input.

13435 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
13436 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
13437 (mark_memory): Mark Lisp_Objects only if pointers might hide in
13438 objects, as mark_maybe_pointer will catch them otherwise.
13439 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
13440 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.

13447 2012-04-07 Eli Zaretskii <eliz@gnu.org>
13449 Support building on MS-Windows with libxml2.
13451 * makefile.w32-in (OBJ2): Add xml.$(O).
13452 (GLOBAL_SOURCES): Add xml.c.
13453 ($(BLD)/xml.$(O)): New dependency list.
13455 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
13456 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
13457 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
13458 [!WINDOWSNT]: New macros.
13459 (init_libxml2_functions, libxml2_loaded_p): New functions.
13460 (parse_region): Call fn_xmlCheckVersion instead of using the macro
13461 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
13462 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
13463 Calls xmlCleanupParser only if libxml2 was loaded (or statically
13465 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
13466 Call init_libxml2_functions before calling libxml2 functions.
13467 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
13469 * emacs.c: Don't include libxml/parser.h.
13470 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
13471 xmlCleanupParser directly.
13473 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
13475 2012-04-07 Eli Zaretskii <eliz@gnu.org>
13477 * indent.c (Fvertical_motion): If there is a display string at
13478 point, use it.vpos to compute how many lines to backtrack after
13479 move_it_to point. (Bug#11133)
13481 2012-04-06 Eli Zaretskii <eliz@gnu.org>
13483 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
13484 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
13485 about subtle differences between FETCH_CHAR* and STRING_CHAR*
13486 macros related to unification of CJK characters. For the details,
13487 see the discussion following the message here:
13488 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
13490 2012-04-04 Chong Yidong <cyd@gnu.org>
13492 * keyboard.c (Vdelayed_warnings_list): Doc fix.
13494 2012-04-01 Eli Zaretskii <eliz@gnu.org>
13496 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA

13504 2012-03-31 Eli Zaretskii <eliz@gnu.org>
13506 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
13507 position we get to after a call to move_it_to fails the
13508 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
13509 only if we wind up in a string from display property. (Bug#11063)
13511 * window.c (Fdelete_other_windows_internal): Invalidate the row
13512 and column information about mouse highlight, so that redisplay
13513 restores it after reallocating the glyph matrices. (Bug#7464)
13515 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
13516 string comes from a `display' text property, use the buffer
13517 position of that property as if we actually saw that position in
13519 (move_it_by_lines): Remove the assertion that
13520 "it->current_x == 0 && it->hpos == 0" which can be legitimately
13521 violated when there's a before-string at the beginning of a line.
13524 2012-03-30 Eli Zaretskii <eliz@gnu.org>
13526 * xdisp.c (append_space_for_newline): If the default face was
13527 remapped, use the remapped face for the appended newline.
13528 (extend_face_to_end_of_line): Use the remapped default face for
13529 extending the face to the end of the line.
13530 (display_line): Call extend_face_to_end_of_line when the default
13531 face was remapped. (Bug#11068)
13533 2012-03-29 Eli Zaretskii <eliz@gnu.org>
13535 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
13537 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
13539 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
13541 2012-03-27 Glenn Morris <rgm@gnu.org>

13553 * keyboard.c (Vselection_inhibit_update_commands): New variable.
13554 (command_loop_1): Use it; inhibit selection update for
13555 handle-select-window too (Bug#8996).

13561 2012-03-25 Kenichi Handa <handa@m17n.org>
13563 * dispextern.h (struct glyph): Change the bit length of
13564 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
13566 2012-03-24 Eli Zaretskii <eliz@gnu.org>
13568 * s/ms-w32.h (tzname): Include time.h before redirecting to

13573 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
13576 * xterm.c (XTread_socket): Only modify handling_signal if
13577 !SYNC_INPUT. (Bug#11080)
13579 2012-03-23 Eli Zaretskii <eliz@gnu.org>
13581 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
13582 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
13583 when fetching a multibyte character consumes more bytes than
13584 CHAR_BYTES returns, due to unification of CJK characters in
13585 string_char. (Bug#11073)
13587 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
13589 * process.c (wait_reading_process_output): Handle pty disconnect
13590 by refraining from sending oneself a SIGCHLD (bug#10933).
13592 2012-03-22 Chong Yidong <cyd@gnu.org>
13594 * dispextern.h (struct it): New member string_from_prefix_prop_p.

13621 2012-03-18 Eli Zaretskii <eliz@gnu.org>
13623 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
13624 that is not from display property, accept the row as a "cursor
13625 row" if one of the string's character has a non-nil `cursor'
13626 property. Fixes cursor positioning when there are newlines in
13627 overlay strings, e.g. in icomplete.el. (Bug#11035)
13629 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
13631 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
13633 2012-03-12 Chong Yidong <cyd@gnu.org>
13635 * eval.c (inhibit_lisp_code): Rename from
13636 inhibit_window_configuration_change_hook; move from window.c.
13638 * xfns.c (unwind_create_frame_1, Fx_create_frame):
13639 * window.c (run_window_configuration_change_hook)
13640 (syms_of_window): Callers changed.
13642 2012-03-11 Chong Yidong <cyd@gnu.org>
13644 * keymap.c (Fkey_description): Doc fix (Bug#9700).

13648 2012-03-10 Chong Yidong <cyd@gnu.org>
13650 * frame.c (other_visible_frames): Don't assume the selected frame
13651 is visible (Bug#10955).
13653 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
13655 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
13657 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
13659 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
13660 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
13663 2012-03-03 Glenn Morris <rgm@gnu.org>
13665 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
13667 2012-03-02 Eli Zaretskii <eliz@gnu.org>

13670 position past the first glyph_row that ends at ZV. (Bug#10902)
13671 (redisplay_window, next_element_from_string): Fix typos in
13673 (redisplay_window): Pass to move_it_vertically the margin in
13674 pixels, not in screen lines.
13676 2012-03-02 Glenn Morris <rgm@gnu.org>
13678 * buffer.c (buffer-list-update-hook): Doc fix.
13680 2012-02-29 Eli Zaretskii <eliz@gnu.org>
13682 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
13683 push_it before setting up the iterator for the first overlay
13684 string, even if we have an empty string loaded.
13685 (next_overlay_string): If there's an empty string on the iterator
13686 stack, pop the stack. (Bug#10903)
13688 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
13690 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
13691 Suggested by Stefan Monnier in
13692 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
13693 * alloc.c (widen_to_Lisp_Object): New static function.
13694 (mark_memory): Also mark Lisp_Objects by fetching pointer words
13695 and widening them to Lisp_Objects. This would work even if
13696 USE_LSB_TAG is defined and wide integers are used, which might
13697 happen in a future version of Emacs.
13699 2012-02-25 Chong Yidong <cyd@gnu.org>
13701 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
13704 * xselect.c (Fx_selection_exists_p): Doc fix.

13741 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
13742 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
13743 It's useless in that case, and it can cause problems on hosts
13744 that allocate halves of EMACS_INT values separately.
13745 Reported by Dan Horák. Diagnosed by Andreas Schwab in
13746 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
13747 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
13748 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
13749 it avoids undefined behavior on hosts where shifting right by more
13750 than the word width has undefined behavior.
13752 2012-02-19 Chong Yidong <cyd@gnu.org>
13754 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
13755 (Funhandled_file_name_directory, Ffile_name_as_directory)

13797 * window.c (Fdelete_window_internal): Invalidate the mouse
13798 highlight (Bug#9904).

13876 * character.c (char_width): Return EMACS_INT, not int.
13877 (char_width, c_string_width): Check for overflow when

13911 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
13912 first 2 arguments are identical. This makes inserting large

14367 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
14368 verifies glyph row's hash code--we have just reallocated the

14534 is set, removing the need for VIRT_ADDRESS_VARIES.
14535 (PURE_P): Use a more-efficient implementation that needs just one

14552 behave as if the cursor position were at the window margin.
14554 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
14555 and the cursor position is out of bounds, behave as if the cursor
14556 position were at the window margin. (Bug#10075)
14558 2011-11-18 Chong Yidong <cyd@gnu.org>
14560 * window.c (Fwindow_combination_limit): Make first argument

14582 compute_line_metrics.
14583 (compute_line_metrics): Call row_hash, instead of computing the
14586 * dispnew.c (verify_row_hash): Call row_hash for computing the
14587 hash code of a row, instead of duplicating code from xdisp.c.
14589 * dispextern.h (row_hash): Add prototype.
14591 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
14593 * frame.c (delete_frame): Don't delete the terminal when the last

14642 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
14643 with user-defined heap size. Bump the default size of the temacs

14647 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
14648 current_matrix and desired_matrix. (Bug#9990)
14649 (verify_row_hash) [XASSERTS]: New function.

14694 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
14696 Avoid some portability problems by eschewing 'extern inline' functions.
14697 The trivial performance wins aren't worth the portability hassles; see
14698 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
14700 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

14748 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
14749 This is also needed for porting to any host where GC_MARK_STACK is
14750 not GC_MAKE_GCPROS_NOOPS.
14751 (which_symbols): Use it.

14766 * xmenu.c (cleanup_widget_value_tree): New function.
14767 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
14768 calling free_menubar_widget_value_tree directly (Bug#9830).

14774 (window_box_width, window_box_left, window_box_left_offset)
14775 (window_box_right, window_box_right_offset): Declare extern.
14776 Otherwise, these inline functions do not conform to C99 and
14777 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
14778 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
14779 * intervals.c (adjust_intervals_for_insertion)

14782 (static_offset_intervals): Remove.
14783 (offset_intervals): Rewrite using the old contents of
14784 static_offset_intervals. The old version didn't conform to C99
14785 because an extern inline function contained a reference to an
14786 identifier with static linkage.
14788 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
14790 * keyboard.c (interrupt_signal): Don't call kill-emacs while in

14808 (Fwindow_vscroll): Doc fix.

14810 argument, since it makes no sense to pass a live window and for
14811 consistency with window-child.

14852 official. Move initialization of image_cache_refcount and
14853 dpyinfo_refcount before calling init_frame_faces (Bug#9943).

15021 (w32font_open_internal, compute_metrics):
15022 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
15023 instead of calling the "wide" APIs directly.

15098 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
15099 * editfns.c: Rewrite current-time-zone so that it invokes
15100 the equivalent of (format-time-string "%Z") to get the time zone name.
15101 This fixes a bug when the time zone name contains characters that
15102 need converting from the system time locale to Emacs internal format.
15103 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
15104 that patch fixed format-time-string to do the conversion, but
15105 I forgot to fix current-time-zone.
15106 (format_time_string): New function, containing most of
15107 what Fformat_time_string used to contain.
15108 (Fformat_time_string): Rewrite in terms of format_time_string.
15109 This doesn't change this function's behavior.
15110 (current-time-zone): Rewrite to use format_time_string.
15111 This fixes the bug reported by Michael Schierl in
15112 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
15113 Jason Rumney's 2007-06-07 change worked around this bug, but
15115 * systime.h (tzname, timezone): Remove no-longer-used declarations.
15117 2011-10-19 Eli Zaretskii <eliz@gnu.org>
15119 * xdisp.c (start_display): If the character at POS is displayed
15120 via a display vector, reset IT->current.dpvec_index to zero.
15121 (try_window_reusing_current_matrix): If a line ends in a display
15122 vector or the next line starts in a display vector, continue
15123 redrawing the window even though the character position of
15124 start_row was reached.
15127 2011-10-18 Chong Yidong <cyd@gnu.org>
15129 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
15130 with nobreak-char-display too.
15132 2011-10-18 Eli Zaretskii <eliz@gnu.org>
15134 Fix part 3 of bug#9771.
15135 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
15136 (bidi_resolve_neutral): Don't enter the expensive loop looking for
15137 non-neutral characters if the current character is a paragraph
15138 separator (a.k.a. Newline). This avoids running the same
15139 expensive loop twice, once when we consume the preceding newline
15140 and the other time when the line actually needs to be displayed.
15141 Avoid the loop when we see neutrals on the base embedding level
15142 following a character whose directionality is the same as the
15143 paragraph's. This avoids running the expensive loop when a line
15144 ends in a long sequence of neutrals, like control characters.
15145 Add assertion against STRONG_AL type. Slightly rearrange code
15146 that determines the type of a neutral given the first non-neutral
15148 (bidi_level_of_next_char): Set next_en_pos to zero when
15149 invalidating its info.
15151 2011-10-17 Eli Zaretskii <eliz@gnu.org>
15153 * xdisp.c (push_display_prop): Determine whether to record string
15154 or buffer position by IT->string, not by IT->method. Allow
15155 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
15156 (move_it_vertically_backward): Don't look for character position
15157 immediately after the newline when in a continuation line.
15160 2011-10-15 Martin Rudalics <rudalics@gmx.at>
15162 * window.c (coordinates_in_window): Rewrite and delabelize
15163 vertical border check. (Bug#5357) (Bug#9618)
15165 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
15167 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
15168 errors in XSetWindowBorder (bug#9310).
15170 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
15172 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
15173 avoid crash when xmalloc overrun checking is enabled.
15175 2011-10-13 Eli Zaretskii <eliz@gnu.org>
15177 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
15178 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
15179 cursor motion with <left> and <right> arrow keys.
15181 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
15182 some callers set that themselves.
15184 2011-10-12 Eli Zaretskii <eliz@gnu.org>
15186 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
15187 display string and the previous row comes from the same string and
15188 is empty. (Bug#9739) (Bug#9738)
15190 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
15192 * doc.c (get_doc_string): Encode file name (bug#9735).
15194 2011-10-12 Eli Zaretskii <eliz@gnu.org>
15196 * bidi.c (bidi_level_of_next_char):
15197 * xdisp.c (get_visually_first_element): Remove old incorrect
15198 comments regarding the Unicode Line Separator character.
15200 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
15202 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
15204 * alloc.c (Fgc_status): Do not access beyond zombies array
15205 boundary if nzombies > MAX_ZOMBIES.
15206 * alloc.c (dump_zombies): Add missing format specifier.
15208 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
15210 * xdisp.c (set_cursor_from_row): Simplify conditionals,
15211 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
15213 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
15214 Some packages use them to denote characters with modifiers.
15216 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
15218 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
15219 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
15220 matching a pp-number. Rename parameter var to var1.
15222 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
15224 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
15226 2011-10-08 Glenn Morris <rgm@gnu.org>
15228 * callint.c (Fcall_interactively): Give a more explicit error for the
15229 'c' case with a non-character input. (Bug#8479)
15231 2011-10-08 Eli Zaretskii <eliz@gnu.org>
15233 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
15235 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
15236 lines that are hscrolled on the left.
15238 * dispnew.c (buffer_posn_from_coords): Account for a possible
15239 presence of header-line. (Bug#4426)
15241 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
15243 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
15244 Don't advertise functionality which we discourage or doesn't work.
15246 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
15248 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
15249 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
15250 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
15251 this makes Emacs dump core during garbage collection on rare
15252 occasions. sizeof is obviously inferior to offsetof here, so
15253 stick with offsetof.
15254 (GC_POINTER_ALIGNMENT): New macro.
15255 (mark_memory): Omit 3rd (offset) arg; caller changed.
15256 Don't assume EMACS_INT alignment is the same as pointer alignment.
15258 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
15260 * keyboard.c (read_key_sequence_remapped): New var.
15261 (read_key_sequence): Compute remapping in the right buffer.
15262 (command_loop_1): Use read_key_sequence's remapping directly.
15264 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
15266 * dired.c (file_name_completion): Don't expand file name.
15267 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
15268 before checking file name handler.
15270 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
15271 they've been requested explicitly (bug#9591).
15273 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
15275 * keymap.c (Fsingle_key_description): Use make_specified_string
15276 instead of build_string to build string from push_key_description.
15279 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
15281 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
15282 This fixes a Y2038 bug on 64-bit hosts.
15283 * buffer.c (reset_buffer):
15284 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
15285 (Fclear_buffer_auto_save_failure):
15286 Use 0, not -1, to represent an unset failure time, since time_t
15287 might not be signed.
15289 Remove dependency on glibc malloc internals.
15290 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15291 Move back here from lisp.h, but with their new implementations.
15292 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15293 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
15294 * charset.c (charset_table_init): New static var.
15295 (syms_of_charset): Use it instead of xmalloc. This removes a
15296 dependency on glibc malloc internals. See Eli Zaretskii's comment in
15297 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
15298 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15299 Move back to alloc.c.
15300 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15301 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
15303 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
15305 * nsterm.m (windowDidResize): Call x_set_window_size only when
15306 ns_in_resize is true. Otherwise set pixelwidth/height and
15307 call change_frame_size (Bug#9628).
15309 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
15311 Port --enable-checking=all to Fedora 14 x86-64.
15312 * charset.c (syms_of_charset): Also account for glibc malloc's
15313 internal overhead when calculating the initial malloc maximum.
15315 Port --enable-checking=all to Fedora 14 x86.
15316 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15318 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
15319 (overrun_check_realloc, overrun_check_free):
15320 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
15321 That way, xmalloc returns a properly-aligned pointer even if
15322 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
15323 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
15324 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
15325 into account when calculating the initial malloc maximum.
15326 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15327 Move here from alloc.c, so that charset.c can use it too.
15328 Properly align; the old code wasn't right for common 32-bit hosts
15329 when configured with --enable-checking=all.
15330 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15331 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
15333 2011-09-29 Eli Zaretskii <eliz@gnu.org>
15335 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
15338 2011-09-28 Eli Zaretskii <eliz@gnu.org>
15340 * xdisp.c (compute_display_string_end): If there's no display
15341 string at CHARPOS, return -1.
15343 * bidi.c (bidi_fetch_char): When compute_display_string_end
15344 returns a negative value, treat the character as a normal
15345 character not covered by a display string. (Bug#9624)
15347 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
15349 * lread.c (Fread_from_string): Fix typo in docstring.
15351 2011-09-27 Eli Zaretskii <eliz@gnu.org>
15353 * xdisp.c (handle_invisible_prop): If invisible text ends on a
15354 newline, reseat the iterator instead of bidi-iterating there one
15355 character at a time. (Bug#9610)
15356 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
15357 TO_CHARPOS if the bidi iterator is at base embedding level.
15359 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
15361 * lread.c (readevalloop): Use correct code for NBSP.
15362 (read1): Likewise. (Bug#9608)
15364 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
15366 * dbusbind.c (Fdbus_register_signal): When service is not
15367 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
15369 2011-09-25 Glenn Morris <rgm@gnu.org>
15371 * buffer.c (truncate-lines): Doc fix.
15373 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
15375 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
15376 (Fset_window_next_buffers): Doc fix.
15378 2011-09-24 Glenn Morris <rgm@gnu.org>
15380 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
15382 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
15384 Fix minor problems found by static checking.
15385 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
15386 * indent.c (Fvertical_motion): Fix == vs = typo.
15388 2011-09-24 Eli Zaretskii <eliz@gnu.org>
15390 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
15391 Default value is now t. Doc fix.
15393 * indent.c (Fvertical_motion): Compute and apply the overshoot
15394 logic when moving up, not only when moving down. Fix the
15395 confusing name and values of the it_overshoot_expected variable;
15396 logic changes accordingly. (Bug#9254) (Bug#9549)
15398 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
15399 CHARPOS is covered by a display string which includes newlines.
15400 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
15401 is covered by a display string with embedded newlines.
15403 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
15405 * dbusbind.c (Fdbus_register_signal): Add match rule to
15406 Vdbus_registered_objects_table. (Bug#9581)
15407 (Fdbus_register_method, Vdbus_registered_objects_table):
15410 2011-09-24 Jim Meyering <meyering@redhat.com>
15412 do not ignore write error for any output size
15413 The previous change was incomplete.
15414 While it makes emacs --batch detect the vast majority of stdout
15415 write failures, errors were still ignored whenever the output size is
15416 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
15417 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
15418 && echo FAIL: ignored write error
15419 FAIL: ignored write error
15420 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
15421 && echo FAIL: ignored write error
15422 FAIL: ignored write error
15423 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
15425 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
15427 * emacs.c (Fkill_emacs): In noninteractive mode exit
15428 non-successfully if a write error occurred on stdout. (Bug#9574)
15430 2011-09-21 Eli Zaretskii <eliz@gnu.org>
15432 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
15435 * dispextern.h (struct it): Update the comment documenting what
15438 2011-09-20 Eli Zaretskii <eliz@gnu.org>
15440 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
15441 a display string, extend search for cursor position to end of row.
15442 (find_row_edges): If the row ends in a newline from a display
15443 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
15444 Handle the case of a display string with multiple newlines.
15445 (Fcurrent_bidi_paragraph_direction): Fix search for previous
15446 non-empty line. Fixes confusing cursor motion with arrow keys at
15447 the beginning of a line that starts with whitespace.
15449 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
15451 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
15454 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
15456 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
15457 boolean (Bug#9154).
15459 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15461 * xdisp.c (display_line): Record maximum and minimum buffer
15462 positions even if no glyphs were produced (e.g., by a zero-width
15463 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
15464 buffer positions that will be removed from the glyph row because
15466 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
15467 column is beyond frame width: don't subtract 1 "pixel" when
15468 computing width of the stretch.
15469 (reseat_at_next_visible_line_start): Undo the change made on
15470 2011-09-17 that saved paragraph information and restored it after
15471 the call to `reseat'. (Bug#9545)
15473 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15475 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
15476 and turn window cursor on if cleared (Bug#9415).
15478 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
15480 * search.c (boyer_moore): Take unibyte characters from pattern
15481 literally. (Bug#9458)
15483 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15485 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
15487 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
15489 Fix minor problem found by static checking.
15490 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
15491 initialized, to pacify gcc -Wuninitialized.
15493 * fileio.c: Report proper errno when syscall falls.
15494 (Finsert_file_contents): Save and restore errno,
15495 so that report_file_error outputs the correct diagnostic.
15496 (Fwrite_region) [CLASH_DETECTION]: Likewise.
15498 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15500 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
15502 2011-09-17 Eli Zaretskii <eliz@gnu.org>
15504 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
15505 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
15507 2011-09-17 Eli Zaretskii <eliz@gnu.org>
15509 * xdisp.c (reseat_at_next_visible_line_start): Keep information
15510 about the current paragraph and restore it after the call to reseat.
15512 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
15513 (bidi_find_paragraph_start): Search back for paragraph beginning
15514 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
15515 (bidi_move_to_visually_next): Only trigger paragraph-related
15516 computations when the last character is a newline or at EOB, not
15517 just any NEUTRAL_B. (Bug#9470)
15519 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
15520 truncated lines if point is covered by a display string. (Bug#9524)
15522 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
15524 * xselect.c: Relax test for outgoing X longs (Bug#9498).
15525 (cons_to_x_long): New function.
15526 (lisp_data_to_selection_data): Use it. Correct the test for
15527 short-versus-long data; it was negated. Break out of vector
15528 loop, for efficiency, when a long datum is discovered.
15530 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
15532 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
15534 2011-09-16 Eli Zaretskii <eliz@gnu.org>
15536 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
15537 GCC PR/17406) by declaring this function with external scope.
15539 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>

15546 * editfns.c (Fformat): Correctly handle text properties on "%%".
15548 2011-09-15 Eli Zaretskii <eliz@gnu.org>
15550 * xterm.c (x_draw_composite_glyph_string_foreground):

15552 * term.c (encode_terminal_code):
15553 * composite.c (composition_update_it, get_composition_id):
15554 * xdisp.c (get_next_display_element)
15555 (fill_composite_glyph_string): Add comments about special meaning
15556 of TAB characters in a composition.
15558 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
15560 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
15561 This occurs when processing a multibyte format.
15562 Problem reported by Wolfgang Jenker.
15564 2011-09-15 Johan Bockgård <bojohan@gnu.org>
15566 * xdisp.c (try_cursor_movement): Only check for exact match if
15567 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
15569 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
15571 Remove unused external symbols.
15572 * dispextern.h (calc_pixel_width_or_height): Remove decl.
15573 * xdisp.c (calc_pixel_width_or_height): Now static.
15574 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
15575 * indent.c (check_display_width):
15576 * w32term.c: Fix comment to match code.
15577 * xterm.c, xterm.h (x_catching_errors): Remove.
15579 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
15581 * xselect.c: Use signed conversions more consistently (Bug#9498).
15582 (selection_data_to_lisp_data): Assume incoming selection data are
15583 signed integers, not unsigned. This is to be consistent with
15584 outgoing selection data, which was modified to use signed integers
15585 in as part of the fix to Bug#9196 in response to Jan D.'s comment
15586 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
15587 expects long, not unsigned long.
15589 2011-09-14 Eli Zaretskii <eliz@gnu.org>
15591 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
15592 computation of loop end. Reported by Johan Bockgård
15595 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
15597 * frame.c (Fother_visible_frames_p): Function deleted.
15599 2011-09-12 Eli Zaretskii <eliz@gnu.org>
15601 * indent.c (compute_motion): Process display vector front to back
15602 rather than the other way around. (Bug#2496)
15604 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
15606 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
15608 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
15610 * minibuf.c (Fread_from_minibuffer): Doc fix.
15612 2011-09-11 Eli Zaretskii <eliz@gnu.org>
15614 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
15615 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
15617 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
15619 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
15620 value for non-existent files.
15622 2011-09-11 Eli Zaretskii <eliz@gnu.org>
15624 * fileio.c (Finsert_file_contents): If the file cannot be opened,
15625 set its "size" to -1. This will set the modtime_size field of
15626 the corresponding buffer to -1, which is what
15627 verify-visited-file-modtime expects for files that do not exist.
15630 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
15632 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
15634 * lisp.h: ... from here. push_key_description is no longer
15635 defined in keyboard.c, so its declaration should not be in
15636 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
15637 logically belongs with push_key_description.
15639 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
15641 * buffer.h: Include <sys/types.h> instead of <time.h>.
15642 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
15643 Problem reported by Herbert J. Skuhra.
15645 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
15647 * xml.c (parse_region): Make the parsing work for
15648 non-comment-starting XML files again (bug#9144).
15650 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
15652 * image.c (gif_load): Fix calculation of bottom and right corner.
15655 2011-09-10 Eli Zaretskii <eliz@gnu.org>
15657 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
15658 redisplay in small windows.
15660 2011-09-09 Eli Zaretskii <eliz@gnu.org>
15662 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
15664 2011-09-08 Martin Rudalics <rudalics@gmx.at>
15666 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
15667 Operate on live windows only.
15669 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
15671 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
15673 2011-09-07 Eli Zaretskii <eliz@gnu.org>
15675 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
15676 only under bidi iteration.
15678 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
15680 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
15682 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15684 isnan: Fix porting problem to Solaris 10 with bundled gcc.
15685 Without this fix, the command to link temacs failed due to an
15686 undefined symbol __builtin_isnan. This is because
15687 /usr/include/iso/math_c99.h #defines isnan(x) to
15688 __builtin_isnan(x), but the bundled gcc, which identifies itself
15689 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
15691 * floatfns.c (isnan): #undef, and then #define to a clone of
15693 (Fisnan): Always define, since it's always available now.
15694 (syms_of_floatfns): Always define isnan at the Lisp level.
15696 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15698 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
15700 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15702 * fileio.c: Fix bugs with large file offsets (Bug#9428).
15703 The previous code assumed that file offsets (off_t values) fit in
15704 EMACS_INT variables, which is not true on typical 32-bit hosts.
15705 The code messed up by falsely reporting buffer overflow in cases
15706 such as (insert-file-contents "big" nil 1 2) into an empty buffer
15707 when "big" contains more than 2**29 bytes, even though this
15708 inserts just one byte and does not overflow the buffer.
15709 (Finsert_file_contents): Store file offsets as off_t
15710 values, not as EMACS_INT values. Check for overflow when
15711 converting between EMACS_INT and off_t. When checking for
15712 buffer overflow or for overlap, take the offsets into account.
15713 Don't use EMACS_INT for small values where int suffices.
15714 When checking for overlap, fix a typo: ZV was used where
15715 ZV_BYTE was intended.
15716 (Fwrite_region): Don't assume off_t fits into 'long'.
15717 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
15719 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
15721 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
15723 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
15725 sprintf-related integer and memory overflow issues (Bug#9412).
15727 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
15728 (esprintf, exprintf, evxprintf): New functions.
15729 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
15730 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
15731 (modify_event_symbol): Do not assume that the length of
15732 name_alist_or_stem is safe to alloca and fits in int.
15733 (Fexecute_extended_command): Likewise for function name and binding.
15734 (Frecursion_depth): Wrap around reliably on integer overflow.
15735 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
15736 since some callers pass EMACS_INT values.
15737 (Fsingle_key_description): Don't crash if symbol name contains more
15738 than MAX_ALLOCA bytes.
15739 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
15740 (get_minibuffer): Arg is now EMACS_INT, not int.
15741 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
15742 (esprintf, exprintf, evxprintf): New decls.
15743 * window.h (command_loop_level, minibuf_level): Reflect API changes.
15745 * dbusbind.c (signature_cat): New function.
15746 (xd_signature, Fdbus_register_signal):
15747 Do not overrun buffer; instead, report string overflow.
15749 * dispnew.c (add_window_display_history): Don't overrun buffer.
15750 Truncate instead; this is OK since it's just a log.
15752 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
15753 even if the time zone offset is outlandishly large.
15754 Don't mishandle offset == INT_MIN.
15756 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
15757 when creating daemon; the previous buffer-overflow check was incorrect.
15759 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
15760 which has the guts of the old verror function.
15762 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
15763 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
15765 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
15766 (font_unparse_xlfd): Don't blindly alloca long strings.
15767 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
15768 fits in int, when using sprintf. Use single snprintf to count
15769 length of string rather than counting it via multiple sprintfs;
15770 that's simpler and more reliable.
15771 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
15772 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
15773 sprintf, in case result does not fit in int.
15775 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
15776 (fontset_from_font): Print it.
15778 * frame.c (tty_frame_count): Now printmax_t, not int.
15779 (make_terminal_frame, set_term_frame_name): Print it.
15780 (x_report_frame_params): In X, window IDs are unsigned long,
15781 not signed long, so print them as unsigned.
15782 (validate_x_resource_name): Check for implausibly long names,
15783 and don't assume name length fits in 'int'.
15784 (x_get_resource_string): Don't blindly alloca invocation name;
15785 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
15788 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
15789 (xg_check_special_colors, xg_set_geometry):
15790 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
15792 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
15793 Use esprintf, not sprintf, in case result does not fit in int.
15795 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
15796 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
15797 it as a large positive number.
15798 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
15799 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
15801 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
15802 in case result does not fit in int.
15804 * print.c (float_to_string): Detect width overflow more reliably.
15805 (print_object): Make sprintf buffer a bit bigger, to avoid potential
15806 buffer overrun. Don't assume list length fits in 'int'. Treat
15807 print length of 0 as 0, not as infinity; to be consistent with other
15808 uses of print length in this function. Don't overflow print length
15809 index. Don't assume hash table size fits in 'long', or that
15810 vectorlike size fits in 'unsigned long'.
15812 * process.c (make_process): Use printmax_t, not int, to format
15813 process-name gensyms.
15815 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
15817 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
15818 to avoid potential buffer overrun.
15820 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
15821 if X resource line is longer than 512 bytes.
15823 * xfns.c (x_window): Make sprintf buffer a bit bigger
15824 to avoid potential buffer overrun.
15826 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
15828 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
15830 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
15832 Integer overflow fixes for scrolling, etc.
15833 Without these, Emacs silently mishandles large integers sometimes.
15834 For example, "C-u 4294967297 M-x recenter" was treated as if
15835 it were "C-u 1 M-x recenter" on a typical 64-bit host.
15837 * xdisp.c (try_window_id): Check Emacs fixnum range before
15838 converting to 'int'.
15840 * window.c (window_scroll_line_based, Frecenter):
15841 Check that an Emacs fixnum is in range before assigning it to 'int'.
15842 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
15843 values converted from Emacs fixnums.
15844 (Frecenter): Don't wrap around a line count if it is out of 'int'
15845 range; instead, treat it as an extreme value.
15846 (Fset_window_configuration, compare_window_configurations):
15847 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
15849 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
15850 that can exceed INT_MAX. Check that EMACS_INT value is in range
15851 before assigning it to the (possibly-narrower) index.
15852 (match_limit): Don't assume that a fixnum can fit in 'int'.
15854 * print.c (print_object): Use ptrdiff_t, not int, for index that can
15857 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
15858 (Fvertical_motion): Don't wrap around LINES values that don't fit
15859 in 'int'. Instead, treat them as extreme values. This is good
15860 enough for windows, which can't have more than INT_MAX lines anyway.
15862 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
15864 * Require libxml/parser.h to avoid compilation warning.
15866 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
15868 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
15869 since this reportedly can destroy thread storage.
15871 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
15873 * syntax.c (find_defun_start): Update all cache variables if
15874 exiting early (Bug#9401).
15876 2011-08-30 Eli Zaretskii <eliz@gnu.org>
15878 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
15880 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
15881 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
15882 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
15884 * term.c (tty_append_glyph): New function.
15885 (produce_stretch_glyph): Static function and its prototype deleted.
15887 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
15890 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
15892 * image.c (parse_image_spec): Check for nonnegative, not for positive,
15893 when checking :margin (Bug#9390).
15894 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
15895 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
15896 so that the name doesn't mislead. All uses changed.
15898 2011-08-28 Johan Bockgård <bojohan@gnu.org>
15900 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
15903 2011-08-27 Eli Zaretskii <eliz@gnu.org>
15905 * xdisp.c (move_it_to): Don't bail out early when reaching
15906 position beyond to_charpos, if we are scanning backwards.
15907 (move_it_vertically_backward): When DY == 0, make sure we get to
15908 the first character in the line after the newline.
15910 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
15912 * ccl.c: Improve and simplify overflow checking (Bug#9196).
15913 (ccl_driver): Do not generate an out-of-range pointer.
15914 (Fccl_execute_on_string): Remove unnecessary check for
15915 integer overflow, noted by Stefan Monnier in
15916 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
15917 Remove a FIXME that didn't need fixing.
15918 Simplify the newly-introduced buffer reallocation code.
15920 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
15922 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
15924 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
15926 Integer and memory overflow issues (Bug#9196).
15928 * doc.c (get_doc_string): Rework so that
15929 get_doc_string_buffer_size is the actual buffer size, rather than
15930 being 1 less than the actual buffer size; this makes xpalloc more
15933 * image.c (x_allocate_bitmap_record, cache_image):
15934 * xselect.c (Fx_register_dnd_atom):
15935 Simplify previous changes by using xpalloc.
15937 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
15938 since either will do and ptrdiff_t is convenient with xpalloc.
15940 * charset.c (charset_table_size)
15941 (struct charset_sort_data.priority): Now ptrdiff_t.
15942 (charset_compare): Don't overflow if priorities differ greatly.
15943 (Fsort_charsets): Don't assume list length fits in int.
15944 Check for size-calculation overflow when allocating sort data.
15945 (syms_of_charset): Allocate an initial charset table that is
15946 just under 64 KiB, to avoid problems with glibc malloc and mmap.
15948 * cmds.c (internal_self_insert): Check for size-calculation overflow.
15950 * composite.h (struct composition.glyph_len): Now int, not unsigned.
15951 The actual value is always <= INT_MAX, and leaving it unsigned made
15952 overflow checking harder.
15954 * dispextern.h (struct glyph_matrix.rows_allocated)
15955 (struct face_cache.size): Now ptrdiff_t, for convenience in use
15956 with xpalloc. The values are still always <= INT_MAX.
15958 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
15960 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
15961 (SAFE_NALLOCA): New macro.
15963 * region-cache.c (struct boundary.pos, find_cache_boundary)
15964 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
15965 (set_cache_region, invalidate_region_cache)
15966 (revalidate_region_cache, know_region_cache, region_cache_forward)
15967 (region_cache_backward, pp_cache):
15968 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
15969 so that ptrdiff_t * can be passed to xpalloc.
15970 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
15971 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
15972 (pp_cache): Don't assume cache_len fits in int.
15973 * region-cache.h: Adjust extern decls to match.
15975 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
15976 EMACS_INT, since either will do, for xpalloc.
15978 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
15979 (xnmalloc, xnrealloc, xpalloc): New functions.
15981 * bidi.c (bidi_shelve_header_size): New constant.
15982 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
15983 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
15985 * bidi.c (bidi_cache_shrink):
15986 * buffer.c (overlays_at, overlays_in, record_overlay_string)
15988 Don't update size of array until after memory allocation succeeds,
15989 because xmalloc/xrealloc may not return.
15990 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
15991 now that we have proper integer overflow checking.
15992 (record_overlay_string, overlay_strings): Catch overflows when
15993 calculating size of overlay_str_buf.
15995 * callproc.c (Fcall_process): Check for size overflow when
15996 calculating size of args2.
15997 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
15998 Normally we prefer signed values, but sticking with ptrdiff_t would
15999 require adding more-complicated checks.
16001 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
16002 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
16003 Redo buffer-overflow calculations to avoid integer overflow.
16004 Add a FIXME comment where memory seems to be over-allocated.
16006 * character.c (Fstring): Check for size-calculation overflow.
16008 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
16009 unnecessary integer overflow. Check for size overflow.
16010 (encode_coding_object): Don't update size until xmalloc succeeds.
16012 * composite.c (get_composition_id): Check for overflow in glyph
16013 length calculations.
16015 Integer and memory overflow fixes for display code.
16016 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
16017 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
16018 (scrolling_window): Check for overflow in size calculations.
16019 (line_draw_cost, realloc_glyph_pool, add_row_entry):
16020 Don't assume glyph table len fits in int.
16021 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
16022 (row_table_size): Now ptrdiff_t, not int.
16023 (scrolling_window): Avoid overflow in size calculations.
16024 Don't update size until allocation succeeds.
16025 * fns.c (concat): Check for overflow in size calculations.
16026 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.

16042 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
16044 * emacs.c (main): Do not reallocate argv, since there is a null at
16045 the end that can be overwritten, and this way there's no need to
16046 worry about size-calculation overflow.
16047 (sort_args): Check for size-calculation overflow.

16164 (Fx_change_window_property): Use ptrdiff_t, not int, to count
16165 sizes, since they can exceed INT_MAX in size. Check for size

16176 (X_LONG_MIN): New macros.
16177 Use them to make the following changes clearer.
16178 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.

16180 future maintainers not to raise the value too much later.
16181 (SELECTION_QUANTUM): Remove, replacing with ...
16182 (selection_quantum): ... new function, which avoids overflow.
16184 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
16185 assumption that selection length fits in 'int'.

16202 Don't store size until memory allocation succeeds.
16203 (x_get_window_property): Plug memory leak on memory exhaustion.
16204 Don't double-block input; malloc is safe here. Don't assume 2**34
16205 - 4 fits in unsigned long. Add an xassert to check
16206 XGetWindowProperty overflow. Be more careful about overflow
16207 calculations, and distinguish size from memory overflow better.
16208 (receive_incremental_selection): When tracing, don't assume
16209 unsigned int is less than INT_MAX.
16210 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory

16214 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
16215 result parameters unless successful. Rely on cons_to_unsigned
16216 to report problems with elements; the old code wasn't right anyway.
16217 (x_check_property_data): Check for int overflow; we cannot use
16218 a wider type due to X limits.

16251 * lisp.h (hash_lookup, hash_put):
16252 * minibuf.c (Ftest_completion):
16253 Use ptrdiff_t for hash table indexes, not int (which is too
16254 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
16255 32-bit --with-wide-int hosts).
16257 * charset.c (Fdefine_charset_internal): Check for integer overflow.
16258 Add a FIXME comment about memory leaks.

16296 Change bufsize argument back to int, undoing my 2011-03-30 change.
16297 We prefer signed types, and int is wide enough here.
16298 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
16299 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
16300 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
16301 length, not size_t. Use ptrdiff_t for index, not int.
16302 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
16303 possibility of integer overflow.

16331 Prefer int to unsigned where either will do.
16332 (tiff_handler): New function, combining the cores of the
16333 old tiff_error_handler and tiff_warning_handler.

16335 stack buffer overflows. It uses only the features of vsnprintf
16336 that are common to both POSIX and native Microsoft.
16337 (tiff_error_handler, tiff_warning_handler): Use it.
16338 (tiff_load, gif_load, imagemagick_load_image):
16339 Don't assume :index value fits in 'int'.
16340 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.

16385 positioning on the newline at EOL of R2L text within L2R
16386 paragraph, and vice versa.
16387 (try_cursor_movement): Check continued rows, in addition to
16388 continuation rows. Fixes unwarranted scroll when point enters a
16389 continued line of R2L text within an L2R paragraph, or vice versa.
16390 (cursor_row_p): Consider the case of point being equal to
16391 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving

16420 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
16421 instead of CHAR_TO_BYTE. Fixes a crash when a completion
16422 candidate is selected by the mouse, and that candidate has a
16423 composed character under the mouse.
16425 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
16426 coordinates reported by pos-visible-in-window-p for a composed

16436 consider it a hit if to_charpos is anywhere in the range of the
16437 composed buffer positions.
16439 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
16441 * image.c (gif_load): Don't assume that each subimage has the same
16442 dimensions as the base image. Handle disposal method that is
16443 "undefined" by the gif spec (Bug#9335).
16445 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
16447 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

16457 a composition, take its buffer position from IT->cmp_it.charpos.
16458 Fixes cursor positioning at the beginning of a line that begins
16459 with a composed character.
16461 2011-08-18 Eli Zaretskii <eliz@gnu.org>
16463 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
16464 character bidirectional type, use STRONG_L instead. Fixes crashes
16465 in a buffer produced by `describe-categories'.
16467 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
16468 members before the level stack, so they would be saved and
16469 restored when copying iterator state. Fixes incorrect reordering
16470 around TABs covered by display properties.
16472 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
16474 * process.c (Fnetwork_interface_list): Correctly determine buffer size.
16476 2011-08-17 Chong Yidong <cyd@stupidchicken.com>
16478 * eval.c (internal_condition_case, internal_condition_case_1)
16479 (internal_condition_case_2, internal_condition_case_n):
16480 Remove unnecessary aborts (Bug#9081).
16482 2011-08-17 Eli Zaretskii <eliz@gnu.org>
16484 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
16485 has no `load' handler, try opening the file locally. (Bug#9311)
16487 2011-08-16 Ken Brown <kbrown@cornell.edu>
16489 * gmalloc.c: Expand comment.
16491 2011-08-16 Eli Zaretskii <eliz@gnu.org>
16493 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
16494 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.
16496 2011-08-16 Ken Brown <kbrown@cornell.edu>
16498 Fix memory allocation problems in Cygwin build (Bug#9273).
16500 * unexcw.c ( __malloc_initialized): Declare external variable.

16505 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the
16507 (_free_internal_nolock) [CYGWIN]: Ignore requests to free storage
16508 in the static heap.
16509 [CYGWIN] (special_realloc): New function.
16510 (_realloc_internal_nolock) [CYGWIN]: Use the new function on
16511 requests to realloc storage in the static heap.
16513 2011-08-15 Paul Eggert <eggert@cs.ucla.edu>
16515 * bidi.c (bidi_initialize): Remove unused local.
16517 2011-08-15 Eli Zaretskii <eliz@gnu.org>
16520 * biditype.h: Remove file.

16522 * deps.mk (bidi.o): Remove biditype.h and bidimirror.h.
16524 * dispextern.h: Fix a typo in the comment to bidi_type_t.
16526 * chartab.c: Improve commentary for the uniprop_table API.
16528 * bidi.c (bidi_paragraph_init): Support zero value of
16529 bidi_ignore_explicit_marks_for_paragraph_level.
16530 (bidi_initialize): Use uniprop_table instead of including
16531 biditype.h and bidimirror.h.
16533 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
16534 coordinates of the iterator when restoring from ppos_it.
16537 2011-08-14 Kenichi Handa <handa@m17n.org>
16539 * process.c (create_process): Call setup_process_coding_systems
16540 after the pid of the process is set to -1 (Bug#8162).
16542 2011-08-14 Eli Zaretskii <eliz@gnu.org>
16544 * xdisp.c (move_it_in_display_line_to): Don't invoke
16545 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
16546 ppos_it. Fixes vertical cursor motion when line beginning is
16547 covered by an image. (Bug#9296)
16549 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
16551 * nsterm.h (ns_run_ascript): Declare.
16552 (NSAPP_DATA2_RUNASSCRIPT): Define.
16554 * nsfns.m (as_script, as_result, as_status): New static variables.
16555 (ns_run_ascript): New function.
16556 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
16557 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
16558 the event loop. Get status from as_status (Bug#7276).
16560 * nsterm.m (sendEvent): If event is NSApplicationDefined and
16561 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
16562 the event loop (Bug#7276).
16564 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
16566 * gnutls.c (QCgnutls_bootprop_priority)
16567 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
16568 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
16569 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
16570 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
16571 (QCgnutls_bootprop_verify_hostname_error)
16572 (QCgnutls_bootprop_callbacks_verify): Rename from
16573 Qgnutls_bootprop_..., all uses changed.
16575 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
16578 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
16580 * xfaces.c (Qframe_set_background_mode): Now static.
16581 * dispextern.h (Qframe_set_background_mode): Remove decl.

16585 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
16587 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
16588 (Fnetwork_interface_list): Allocate in increments of bytes instead
16589 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
16590 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
16592 (struct ifflag_def): notrailers is smart on OSX.
16593 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
16594 Get hardware address with getifaddrs if available.
16596 2011-08-12 Eli Zaretskii <eliz@gnu.org>
16598 * xdisp.c (iterate_out_of_display_property): xassert that
16599 IT->position is set to within IT->object's boundaries. Break from
16600 the loop as soon as EOB is reached; avoids infloops in redisplay
16601 when IT->position is set up wrongly due to some bug.
16602 Set IT->current to match the bidi iterator unconditionally.
16603 (push_display_prop): Allow GET_FROM_STRING as IT->method on
16604 entry. Force push_it to save on the stack the current
16605 buffer/string position, to be restored by pop_it. Fix flags in
16606 the iterator structure wrt the object coming from a display
16607 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
16608 properties. (Bug#9284)
16610 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
16612 * fontset.c (fontset_get_font_group): Add proper type checks.
16615 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16617 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
16618 and LC_VERSION_MIN_MACOSX.
16619 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
16620 (dump_it) [LC_FUNCTION_STARTS]: Use it.
16622 2011-08-08 Eli Zaretskii <eliz@gnu.org>
16624 * xdisp.c (forward_to_next_line_start): Allow to use the
16625 no-display-properties-and-no-overlays under bidi display.
16626 Set disp_pos in the bidi iterator to avoid searches for display
16627 properties and overlays.
16629 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
16631 * editfns.c (Fset_time_zone_rule): Document relationship with the
16634 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
16635 the font entity extracted from the cache (Bug#8109).
16637 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
16639 * composite.c (autocmp_chars): Don't reset point. That is done by
16640 restore_point_unwind (Bug#5984).
16642 2011-08-07 Juri Linkov <juri@jurta.org>
16644 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
16645 to show the arg `TIME' instead of `TIMEVAL'.
16647 2011-08-06 Eli Zaretskii <eliz@gnu.org>
16649 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
16650 display property strides EOL and includes a newline, as in
16651 longlines-mode. (Bug#9254)
16652 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
16653 word-wrap under bidirectional display. (Bug#9224)
16655 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
16656 is non-zero, even if the data buffer is NULL. Fixes a crash in
16657 vertical-motion with longlines-mode. (Bug#9254)
16659 2011-08-05 Eli Zaretskii <eliz@gnu.org>
16661 * bidi.c <bidi_cache_total_alloc>: Now static.
16662 (bidi_initialize): Initialize bidi_cache_total_alloc.
16664 * xdisp.c (display_line): Release buffer allocated for shelved bidi
16667 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
16668 amount allocated this far in `bidi_cache_total_alloc'.
16669 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
16670 non-zero, only free the data buffer without restoring the cache
16671 contents. All callers changed.
16673 * dispextern.h (bidi_unshelve_cache): Update prototype.
16675 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
16676 (move_it_in_display_line, move_it_to)
16677 (move_it_vertically_backward, move_it_by_lines): Replace the call
16678 to xfree to an equivalent call to bidi_unshelve_cache.
16679 (move_it_in_display_line_to): Fix logic of returning
16680 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
16682 2011-08-05 Eli Zaretskii <eliz@gnu.org>
16684 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
16685 came from a string character with a `cursor' property. (Bug#9229)
16687 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
16689 * Makefile.in (LIB_PTHREAD): New variable.
16690 (LIBES): Add LIB_PTHREAD (Bug#9216).
16692 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
16693 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
16695 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
16697 * regex.c (re_iswctype): Remove some redundant boolean conversions.
16699 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
16701 * xterm.c (x_find_topmost_parent): New function.
16702 (x_set_frame_alpha): Find topmost parent window with
16703 x_find_topmost_parent and set the property there also (bug#9181).
16704 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
16706 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
16708 * callproc.c (Fcall_process): Avoid vfork clobbering
16709 the local vars buffer, coding_systems, current_dir.
16711 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
16713 * keymap.c (Fmake_composed_keymap): Move to subr.el.
16715 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
16717 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
16718 so that it is not optimized away.
16720 * xdisp.c (compute_display_string_pos): Remove unused local.
16722 2011-08-02 Eli Zaretskii <eliz@gnu.org>
16724 Fix slow cursor motion and scrolling in large buffers with
16725 selective display, like Org Mode buffers. (Bug#9218)
16727 * dispextern.h (struct bidi_it): New member disp_prop_p.
16729 * xdisp.c: Remove one-slot cache of display string positions.
16730 (compute_display_string_pos): Accept an additional argument
16731 DISP_PROP_P; callers changed. Scan at most 5K characters forward
16732 for a display string or property. If found, set DISP_PROP_P
16735 * bidi.c (bidi_fetch_char): Accept an additional argument
16736 DISP_PROP_P, and pass it to compute_display_string_pos.
16737 Only handle text covered by a display string if DISP_PROP_P is returned
16738 non-zero. All callers of bidi_fetch_char changed.
16740 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
16742 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
16744 2010-12-03 Don March <don@ohspite.net>
16746 * keymap.c (Fdefine_key): Fix non-prefix key error message when
16747 last character M-[char] is translated to ESC [char] (bug#7541).
16749 2011-08-02 Kenichi Handa <handa@m17n.org>
16751 * lisp.h (uniprop_table): Extern it.
16753 * chartab.c (uniprop_table): Make it non-static.
16755 2011-08-01 Eli Zaretskii <eliz@gnu.org>
16757 * xdisp.c (forward_to_next_line_start): Accept additional argument
16758 BIDI_IT_PREV, and store into it the state of the bidi iterator had
16760 (reseat_at_next_visible_line_start): Use the bidi iterator state
16761 returned by forward_to_next_line_start to restore the state of
16762 it->bidi_it after backing up to previous newline. (Bug#9212)
16764 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
16766 * regex.c (re_comp): Protoize.
16767 (re_exec): Fix return type.
16768 (regexec): Fix type of `ret'. (Bug#9203)
16770 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16772 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
16773 This is needed if max-image-size is a floating-point number.
16775 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
16777 * print.c (print_object): Print empty symbol as ##.
16779 * lread.c (read1): Read ## as empty symbol.
16781 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
16783 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
16784 setting frame foreground color (Bug#9175).
16785 (x_set_background_color): Likewise.
16787 * nsmenu.m (-setText): Size tooltip dimensions precisely to
16788 contents (Bug#9176).
16789 (EmacsTooltip -init): Remove bezels and add shadows to
16792 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
16793 or scroll bar (Bug#8470).
16795 * nsfont.m (nsfont_open): Remove assignment to voffset and
16796 unnecessary vars hshink, expand, hd, full_height, min_height.
16797 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
16799 * nsterm.h (nsfont_info): Remove voffset field.
16801 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
16803 Implement strike-through and overline on NextStep (Bug#8863).
16805 * nsfont.m (nsfont_open): Use underline position provided by font,
16806 instead of hard-coded value of 2.
16807 (nsfont_draw): Call ns_draw_text_decoration instead.
16809 * nsterm.h: Add declaration for ns_draw_text_decoration.
16811 * nsterm.m (ns_draw_text_decoration): New function for drawing
16812 underline, overline, and strike-through.
16813 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
16814 ns_draw_text_decoration. Change treatment of cursor drawing to
16815 accommodate underlining, etc.
16817 2011-07-28 Eli Zaretskii <eliz@gnu.org>
16819 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
16822 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16824 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
16825 Without this fix, if a signal arrives just after memory fills up,
16826 'malloc' might be invoked reentrantly.
16828 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
16829 In other words, assume that every image size is allowed, on non-X
16830 hosts. This assumption is probably wrong, but it lets Emacs compile.
16832 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
16834 * regex.c (re_iswctype): Convert return values to boolean.
16836 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
16838 * xdisp.c (compute_display_string_pos): Don't use cached display
16839 string position if the buffer had its restriction changed.
16842 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16844 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
16846 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16848 Integer signedness and overflow and related fixes. (Bug#9079)
16850 * bidi.c: Integer size and overflow fixes.
16851 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
16852 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
16853 (bidi_cache_find_level_change, bidi_cache_ensure_space)
16854 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
16855 (bidi_find_other_level_edge):
16856 Use ptrdiff_t instead of EMACS_INT where either will do.
16857 This works better on 32-bit hosts configured --with-wide-int.
16858 (bidi_cache_ensure_space): Check for size-calculation overflow.
16859 Use % rather than repeated addition, for better worst-case speed.
16860 Don't set bidi_cache_size until after xrealloc returns, because it
16862 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
16863 (bidi_cache_ensure_space): Also check that the bidi cache size
16864 does not exceed that of the largest Lisp string or buffer. See Eli
16865 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
16867 * alloc.c (__malloc_size_t): Remove.
16868 All uses replaced by size_t. See Andreas Schwab's note
16869 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
16871 * image.c: Improve checking for integer overflow.
16872 (check_image_size): Assume that f is nonnull, since
16873 it is always nonnull in practice. This is one less thing to
16874 worry about when checking for integer overflow later.
16875 (x_check_image_size): New function, which checks for integer
16876 overflow issues inside X.
16877 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
16878 This removes the need for a memory_full check.
16879 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
16880 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
16881 (xbm_read_bitmap_data): Change locals back to 'int', since
16882 their values must fit in 'int'.
16883 (xpm_load_image, png_load, tiff_load):
16884 Invoke x_create_x_image_and_pixmap earlier,
16885 to avoid much needless work if the image is too large.
16886 (tiff_load): Treat overly large images as if
16887 x_create_x_image_and_pixmap failed, not as malloc failures.
16888 (gs_load): Use x_check_image_size.
16890 * gtkutil.c: Omit integer casts.
16891 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
16892 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
16894 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
16896 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
16897 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
16898 would wrongly return t on a 64-bit host.
16900 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
16901 The plain *_OVERFLOW macros run afoul of GCC bug 49705
16902 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
16903 and therefore cause GCC to emit a bogus diagnostic in some cases.
16905 * image.c: Integer signedness and overflow and related fixes.
16906 This is not an exhaustive set of fixes, but it's time to
16907 record what I've got.
16908 (lookup_pixel_color, check_image_size): Remove redundant decls.
16909 (check_image_size): Don't assume that arbitrary EMACS_INT values
16910 fit in 'int', or that arbitrary 'double' values fit in 'int'.
16911 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
16912 (tiff_load, imagemagick_load_image):
16913 Check for overflow in size calculations.
16914 (x_create_x_image_and_pixmap): Remove unnecessary test for
16915 xmalloc returning NULL; that can't happen.
16916 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
16917 (xpm_color_bucket): Use better integer hashing function.
16918 (xpm_cache_color): Don't possibly over-allocate memory.
16919 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
16920 (gif_memory_source):
16921 Use ptrdiff_t, not int or size_t, to record sizes.
16922 (png_load): Don't assume values greater than 2**31 fit in 'int'.
16923 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
16924 either works, as we prefer signed integers.
16925 (tiff_read_from_memory, tiff_write_from_memory):
16926 Return tsize_t, not size_t, since that's what the TIFF API wants.
16927 (tiff_read_from_memory): Don't fail simply because the read would
16928 go past EOF; instead, return a short read.
16929 (tiff_load): Omit no-longer-needed casts.
16930 (Fimagemagick_types): Don't assume size fits into 'int'.
16932 Improve hashing quality when configured --with-wide-int.
16933 * fns.c (hash_string): New function, taken from sxhash_string.
16934 Do not discard information about ASCII character case; this
16935 discarding is no longer needed.
16936 (sxhash-string): Use it. Change sig to match it. Caller changed.
16937 * lisp.h: Declare it.
16938 * lread.c (hash_string): Remove, since we now use fns.c's version.
16939 The fns.c version returns a wider integer if --with-wide-int is
16940 specified, so this should help the quality of the hashing a bit.
16942 * emacs.c: Integer overflow minor fix.
16943 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
16944 Define only if GNU_LINUX.
16945 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
16947 * dispnew.c: Integer signedness and overflow fixes.
16948 Remove unnecessary forward decls, that were a maintenance hassle.
16949 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
16951 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
16952 (scrolling_window): Use ptrdiff_t, not int, for byte count.
16953 (prepare_desired_row, line_draw_cost):
16954 Use int, not unsigned, where either works.
16955 (save_current_matrix, restore_current_matrix):
16956 Use ptrdiff_t, not size_t, where either works.
16957 (init_display): Check for overflow more accurately, and without
16958 relying on undefined behavior.
16960 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
16961 Remove, replacing with the new symbols in lisp.h. All uses changed.
16962 * fileio.c (make_temp_name):
16963 * filelock.c (lock_file_1, lock_file):
16964 * xdisp.c (message_dolog):
16965 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
16966 Use pMd etc. instead.
16967 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
16968 replacing the pWIDE etc. symbols removed from editfns.c.
16970 * keyboard.h (num_input_events): Now uintmax_t.
16971 This is (very slightly) less likely to mess up due to wraparound.
16974 * buffer.c: Integer signedness fixes.
16975 (alloc_buffer_text, enlarge_buffer_text):
16976 Use ptrdiff_t rather than size_t when either will do, as we prefer
16979 * alloc.c: Integer signedness and overflow fixes.
16980 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
16981 (__malloc_size_t): Default to size_t, not to int.
16982 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
16983 (Fgarbage_collect, mark_object_loop_halt, mark_object):
16984 Prefer ptrdiff_t to size_t when either would do, as we prefer
16986 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
16987 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
16988 Now const. Initialize with values that are in range even if char
16990 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
16991 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
16992 These functions do the right thing with sizes > 2**32.
16993 (check_depth): Now ptrdiff_t, not int.
16994 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
16995 Adjust to new way of storing sizes. Check for size overflow bugs
16997 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
16998 slightly wrong anyway, as it missed one instance of
16999 XMALLOC_OVERRUN_CHECK_OVERHEAD.
17000 (refill_memory_reserve): Omit needless cast to size_t.
17001 (mark_object_loop_halt): Mark as externally visible.
17003 * xselect.c: Integer signedness and overflow fixes.
17004 (Fx_register_dnd_atom, x_handle_dnd_message):
17005 Use ptrdiff_t, not size_t, since we prefer signed.
17006 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
17007 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
17008 x_dnd_atoms_size and x_dnd_atoms_length.
17010 * doprnt.c: Prefer signed to unsigned when either works.
17012 * doprnt.c (doprnt):
17014 * xdisp.c (vmessage):
17015 Use ptrdiff_t, not size_t, when using or implementing doprnt,
17016 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
17017 prefer signed arithmetic to avoid comparison confusion.
17018 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
17019 but is a bit tricky.
17021 Assume freestanding C89 headers, string.h, stdlib.h.
17022 * data.c, doprnt.c, floatfns.c, print.c:
17023 Include float.h unconditionally.
17024 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
17025 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
17026 * regex.c: Likewise for stddef.h, string.h.
17027 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
17028 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
17029 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
17030 (STDC_HEADERS): Remove obsolete defines.
17031 * sysdep.c: Include limits.h unconditionally.
17033 Assume support for memcmp, memcpy, memmove, memset.
17034 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
17035 * regex.c (memcmp, memcpy):
17036 Remove; we assume C89 now.
17038 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
17039 (__malloc_safe_bcopy): Remove; no longer needed.
17041 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
17042 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
17043 well either way, and we prefer signed to unsigned.
17045 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
17047 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
17048 closes the connection while we're reading (bug#9182).
17050 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
17052 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
17053 are specified (Bug#9168).
17055 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
17057 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
17058 Found by GCC static checking and --with-wide-int on a 32-bit host.
17060 2011-07-25 Eli Zaretskii <eliz@gnu.org>
17062 * xdisp.c (compute_display_string_pos): Fix logic of caching
17063 previous display string position. Initialize cached_prev_pos to
17064 -1. Fixes slow-down at the beginning of a buffer.
17066 2011-07-24 Eli Zaretskii <eliz@gnu.org>
17068 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
17069 for attrs[LFACE_FONTSET_INDEX].
17071 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
17073 * xml.c (parse_region): Remove unused local
17074 that was recently introduced.
17076 2011-07-23 Eli Zaretskii <eliz@gnu.org>
17078 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
17079 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
17081 * xdisp.c (move_it_in_display_line_to): Record the best matching
17082 position for TO_CHARPOS while scanning the line, and restore it on
17083 exit if none of the characters scanned was an exact match.
17084 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
17085 when exact match is impossible due to invisible text, and the
17086 lines are truncated.
17088 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
17090 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
17093 2011-07-22 Eli Zaretskii <eliz@gnu.org>
17095 Fix a significant slow-down of cursor motion with C-n, C-p,
17096 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
17097 auto-repeat under bidi redisplay in fontified buffers.
17098 * xdisp.c (compute_stop_pos_backwards): New function.
17099 (next_element_from_buffer): Call compute_stop_pos_backwards to
17100 find a suitable prev_stop when we find ourselves before
17102 (reseat): Don't look for prev_stop, as that could mean a very long
17104 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
17105 <cached_disp_overlay_modiff>: Cache for last found display string
17107 (compute_display_string_pos): Return the cached position if asked
17108 about the same buffer in the same area of character positions, and
17109 the buffer wasn't changed since the time the display string
17110 position was cached.
17112 2011-07-22 Eli Zaretskii <eliz@gnu.org>
17114 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
17115 is an integer, which is important for empty lines. (Bug#9149)
17117 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
17119 * frame.c (Fmodify_frame_parameters): In tty case, update the
17120 default face if necessary (Bug#4238).
17122 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
17124 * editfns.c (Fstring_to_char): No need to explain what a character
17125 is in the docstring (Bug#6576).
17127 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
17129 * xml.c (parse_region): Make sure we always return a tree.
17131 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
17133 * xml.c (parse_region): If a document contains only comments,
17136 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
17138 * xml.c (make_dom): Return comments, too.
17140 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
17143 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
17144 and the surrounding thread.
17145 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
17146 rather than fgets, and retry after EINTR. Otherwise, 'emacs
17147 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
17149 * s/openbsd.h (BROKEN_SIGIO): Define.
17150 * unexelf.c (unexec) [__OpenBSD__]:
17151 Don't update the .mdebug section of the Alpha COFF symbol table.
17153 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
17155 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
17158 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
17160 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
17161 This fixes some race conditions on the permissions of any newly
17164 * alloc.c (valid_pointer_p): Use pipe, not open.
17165 This fixes some permissions issues when debugging.
17167 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
17168 If fchown fails to set both uid and gid, try to set just gid,
17169 as that is sometimes allowed. Adjust the file's mode to eliminate
17170 setuid or setgid bits that are inappropriate if fchown fails.
17172 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
17174 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
17175 to compare Lisp_Objects.
17176 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
17177 global_gnutls_log_level, don't mistake it for a Lisp_Object.
17178 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
17180 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
17182 * lread.c (read_integer): Unread even EOF character.
17183 (read1): Likewise. Properly record start position of symbol.
17185 * lread.c (read1): Read `#:' as empty uninterned symbol if no
17186 symbol character follows.
17188 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
17190 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
17191 This works around a problem with the previous change to Fcopy_file.
17192 Recent glibc declares fchown with __attribute__((warn_unused_result)),
17193 and without this change, GCC might complain about discarding
17194 fchown's return value.
17196 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
17198 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
17200 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
17202 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
17204 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
17206 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
17207 it's used from the C level.
17209 * process.c: Use the same condition for POLL_FOR_INPUT in both
17210 keyboard.c and process.c (bug#1858).
17212 2011-07-09 Lawrence Mitchell <wence@gmx.li>
17214 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
17215 (Fgnutls_boot): Use it.
17217 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
17219 * doc.c (Fsubstitute_command_keys): Revert last change.
17221 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
17223 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
17224 quotes the next character, and doesn't affect other longer
17225 sequences (bug#8935).
17227 * lread.c (syms_of_lread): Clarify that is isn't only
17228 `eval-buffer' and `eval-defun' that's affected by
17229 `lexical-binding' (bug#8460).
17231 2011-07-15 Eli Zaretskii <eliz@gnu.org>
17233 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
17234 bidi redisplay when a line includes both an image and is truncated.
17236 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
17238 Fix minor problems found by static checking.
17239 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
17240 (elsz): Now a signed constant, not a size_t var. We prefer signed
17241 types to unsigned, to avoid integer comparison confusion. Without
17242 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
17243 "cannot optimize loop, the loop counter may overflow", a symptom
17245 * indent.c (Fvertical_motion): Mark locals as initialized.
17246 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
17248 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
17250 * search.c (Fre_search_backward): Mention `case-fold-search' in
17251 all the re_search_* functions (bug#8138).
17253 * keyboard.c (Fopen_dribble_file): Document when the file is
17256 2011-07-14 Eli Zaretskii <eliz@gnu.org>
17258 * bidi.c (bidi_dump_cached_states): Fix format of displaying
17261 Support bidi reordering of display and overlay strings.

17263 (compute_display_string_end): Accept additional argument STRING.
17264 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
17265 (reseat_to_string): Initialize bidi_it->string.s and
17266 bidi_it->string.schars.
17267 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
17268 NULL (avoids a crash in bidi_paragraph_init).
17269 Initialize itb.string.lstring.
17270 (init_iterator): Call bidi_init_it only of a valid
17271 buffer position was specified. Initialize paragraph_embedding to
17273 (reseat_to_string): Initialize the bidi iterator.
17274 (display_string): If we need to ignore text properties of
17275 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
17276 original value of -1 will not work with bidi.)
17277 (compute_display_string_pos): First arg is now struct
17278 `text_pos *'; all callers changed. Support display properties on
17280 (compute_display_string_end): Support display properties on Lisp
17282 (init_iterator, reseat_1, reseat_to_string): Initialize the
17283 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
17284 when iterating on a string not from display properties).
17285 (compute_display_string_pos, compute_display_string_end):
17286 Fix calculation of the object to scan. Fixes an error when using
17288 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
17289 base_level_stop; instead, set base_level_stop to BEGV.
17290 Fixes crashes in vertical-motion.
17291 (next_element_from_buffer): Improve commentary for when
17292 the iterator is before prev_stop.
17293 (init_iterator): Initialize bidi_p from the default value of
17294 bidi-display-reordering, not from buffer-local value. Use the
17295 buffer-local value only if initializing for buffer iteration.
17296 (handle_invisible_prop): Support invisible properties on strings
17297 that are being bidi-reordered.
17298 (set_iterator_to_next): Support bidi reordering of C strings and
17300 (next_element_from_string): Support bidi reordering of Lisp
17302 (handle_stop_backwards): Support Lisp strings as well.
17303 (display_string): Support display of R2L glyph rows.
17304 Use IT_STRING_CHARPOS when displaying from a Lisp string.
17305 (init_iterator): Don't initialize it->bidi_p for strings
17307 (reseat_to_string): Initialize it->bidi_p for strings here.
17308 (next_element_from_string, next_element_from_c_string)
17309 (next_element_from_buffer): Add xassert's for correspondence
17310 between IT's object being iterated and it->bidi_it.string
17312 (face_before_or_after_it_pos): Support bidi iteration.
17313 (next_element_from_c_string): Handle the case of the first string
17314 character that is not the first one in the visual order.
17315 (get_visually_first_element): New function, refactored from common
17316 parts of next_element_from_buffer, next_element_from_string, and
17317 next_element_from_c_string.
17318 (tool_bar_lines_needed, redisplay_tool_bar)
17319 (display_menu_bar): Force left-to-right direction. Add a FIXME
17320 comment for making that be controlled by a user option.
17321 (push_it, pop_it): Save and restore the state of the
17322 bidi iterator. Save and restore the bidi_p flag.
17323 (pop_it): Iterate out of display property for string iteration as
17325 (iterate_out_of_display_property): Support iteration over strings.
17326 (handle_single_display_spec): Set up it->bidi_it for iteration
17327 over a display string, and call bidi_init_it.
17328 (handle_single_display_spec, next_overlay_string)
17329 (get_overlay_strings_1, push_display_prop): Set up the bidi
17330 iterator for displaying display or overlay strings.
17331 (forward_to_next_line_start): Don't use the shortcut if
17333 (back_to_previous_visible_line_start): If handle_display_prop
17334 pushed the iterator stack, restore the internal state of the bidi
17335 iterator by calling bidi_pop_it same number of times.
17336 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
17337 and we are bidi-iterating, don't decrement the iterator position;
17338 instead, set the first_elt flag in the bidi iterator, to produce
17340 (reseat_1): Remove redundant setting of string_from_display_prop_p.
17341 (push_display_prop): xassert that we are iterating a buffer.
17342 (push_it, pop_it): Save and restore paragraph_embedding member.
17343 (handle_single_display_spec, next_overlay_string)
17344 (get_overlay_strings_1, reseat_1, reseat_to_string)
17345 (push_display_prop): Set up the `unibyte' member of bidi_it.string
17346 correctly. Don't assume unibyte strings are not bidi-reordered.
17347 (compute_display_string_pos)
17348 (compute_display_string_end): Fix handling the case of C string.
17349 (push_it, pop_it): Save and restore from_disp_prop_p.
17350 (handle_single_display_spec, push_display_prop): Set the
17351 from_disp_prop_p flag.
17352 (get_overlay_strings_1): Reset the from_disp_prop_p flag.
17353 (pop_it): Call iterate_out_of_display_property only if we are
17354 popping after iteration over a string that came from a display
17355 property. Fix a typo in popping stretch info. Add an assertion
17356 for verifying that the iterator position is in sync with the bidi
17358 (handle_single_display_spec, get_overlay_strings_1)
17359 (push_display_prop): Fix initialization of paragraph direction for
17360 string when that of the parent object is not yet determined.
17361 (reseat_1): Call bidi_init_it to resync the bidi

17809 2011-07-05 Paul Eggert <eggert@cs.ucla.edu>
17811 Random fixes. E.g., (random) never returned negative values.
17812 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
17813 subseconds part to the entropy, as that's a bit more random.
17814 Prefer signed to unsigned, since the signedness doesn't matter and
17815 in general we prefer signed. When given a limit, use a
17816 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
17817 latter isn't right if USE_2_TAGS_FOR_INTS.
17818 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
17819 not 0..VALMASK. Don't discard "excess" bits that random () returns.
17821 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
17823 * textprop.c (text_property_stickiness):
17824 Obey Vtext_property_default_nonsticky.

17831 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
17832 This is more efficient than Ffile_directory_p and avoids a minor race.
17834 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
17836 * buffer.c (Foverlay_put): Say what the return value is
17839 * fileio.c (barf_or_query_if_file_exists): Check first if the file
17840 is a directory before asking whether to use the file name
17842 (barf_or_query_if_file_exists): Make the "File is a directory"
17843 error be more correct.
17845 * fns.c (Frequire): Remove the mention of the .gz files, since
17846 that's installation-specific, but keep the mention of
17847 `get-load-suffixes'.
17849 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
17851 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

17854 2011-07-04 Juanma Barranquero <lekktu@gmail.com>
17856 * gnutls.c (Fgnutls_boot): Don't mention :verify-error.
17857 (syms_of_gnutls): Remove duplicate DEFSYM for
17858 Qgnutls_bootprop_verify_hostname_error, an error for
17859 Qgnutls_bootprop_verify_error (which is no longer used).
17861 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
17862 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
17863 Also (re)move comments that are misplaced or no longer relevant.
17865 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
17867 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

17871 * xfaces.c (Finternal_merge_in_global_face): Modify the foreground
17872 and background color parameters if they have been changed.

17892 * lread.c (syms_of_lread): Mention single symbols defined by
17893 `defvar' or `defconst' (bug#7154).
17895 * fns.c (Frequire): Mention .el.gz files (bug#7314).
17896 (Frequire): Mention get-load-suffixes.
17898 2011-07-02 Martin Rudalics <rudalics@gmx.at>
17900 * window.h (window): Remove clone_number slot.

17926 (syms_of_keymap): Defsubr make-composed-keymap.
17927 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

17964 * eval.c (struct backtrace): Simplify and port the data structure.
17965 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
17966 signed bit field, as this assumption is not portable and it makes
17967 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
17968 "char debug_on_exit : 1" as this is not portable either; instead,
17969 use the portable "unsigned int debug_on_exit : 1". Remove unused
17970 member evalargs. Remove obsolete comments about cc bombing out.
17972 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>
17974 * xsettings.c: Include glib-object.h, gio/gio.h if HAVE_GSETTINGS.

18042 (emacs_fixed_get_preferred_height): Use min_width/height from
18043 frames size_hint to set minimum and natural (Bug#8919).
18044 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
18045 and use min_width/height from frames size_hint to set
18046 min_width/height (Bug#8919).
18048 * gtkutil.c (xg_create_frame_widgets): Pass f to emacs_fixed_new.

18138 * print.c (printchar, strout): Check for string overflow.
18139 (PRINTPREPARE, printchar, strout):
18140 Don't set size unless allocation succeeds.
18142 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
18143 for sizes. Check for string overflow more accurately.

18147 * keyboard.h (struct keyboard.kbd_macro_bufsize):
18148 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

18157 (read_integer): Radix is now EMACS_INT, not int,
18158 to improve quality of diagnostics for out-of-range radices.
18159 Calculate buffer size correctly for out-of-range radices.
18160 (read1): Check for integer overflow in radices, and in
18161 read-circle numbers.
18162 (read_escape): Avoid int overflow.
18163 (Fload, openp, read_buffer_size, read1)
18164 (substitute_object_recurse, read_vector, read_list, map_obarray):
18165 Use ptrdiff_t, not int, for sizes.

18185 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
18187 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
18188 The following patches are for when GLYPH_DEBUG && !XASSERT.
18189 * dispextern.h (trace_redisplay_p, dump_glyph_string):
18190 * dispnew.c (flush_stdout):
18191 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
18192 Mark as externally visible.
18193 * dispnew.c (check_window_matrix_pointers): Now static.
18194 * dispnew.c (window_to_frame_vpos):
18195 * xfns.c (unwind_create_frame):

18202 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
18204 (debug_method_add): Use va_list and vsprintf rather than relying
18205 on undefined behavior with wrong number of arguments.
18206 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
18207 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
18208 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
18209 since we're not interested in debugging glyphs with old libraries.
18210 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
18211 GCC 4.6.0's static checking.
18213 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>

18230 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
18231 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
18232 (.bitmaps_last, struct x_output.icon_bitmap):
18233 Use ptrdiff_t, not int, for bitmap indexes.
18234 (x_allocate_bitmap_record): Check for size overflow.
18235 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
18237 Use ptrdiff_t, not int, for overlay counts.
18238 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
18239 * editfns.c (overlays_around, get_pos_property):
18240 * textprop.c (get_char_property_and_overlay):
18241 * xdisp.c (next_overlay_change, note_mouse_highlight):
18242 * xfaces.c (face_at_buffer_position):
18243 * buffer.c (OVERLAY_COUNT_MAX): New macro.
18244 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
18245 (Fnext_overlay_change, Fprevious_overlay_change)
18246 (mouse_face_overlay_overlaps, Foverlays_in):
18247 Use ptrdiff_t, not int, for sizes.
18248 (overlays_at, overlays_in): Check for size-calculation overflow.
18250 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
18252 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
18253 (x_session_initialize): Do not assume string length fits in int.
18255 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
18256 This is unlikely, but can occur if DPI is outlandish.
18258 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
18259 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
18261 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
18262 * xrdb.c (magic_file_p, search_magic_path):
18263 Omit last arg SUFFIX; it was always 0. All callers changed.
18264 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
18266 * xfont.c (xfont_match): Avoid need for strlen.
18268 * xfns.c: Don't assume strlen fits in int.
18269 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
18271 * xdisp.c (message_log_check_duplicate): Return intmax_t,
18272 not unsigned long, as we prefer signed integers. All callers changed.
18273 Detect integer overflow in repeat count.
18274 (message_dolog): Don't assume print length fits in 39 bytes.
18275 (display_mode_element): Don't assume strlen fits in int.
18277 * termcap.c: Don't assume sizes fit in int and never overflow.
18278 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
18279 (gobble_line): Check for size-calculation overflow.
18281 * minibuf.c (Fread_buffer):
18282 * lread.c (intern, intern_c_string):
18283 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
18284 Don't assume string length fits in int.
18286 * keyboard.c (parse_tool_bar_item):
18287 * gtkutil.c (style_changed_cb): Avoid need for strlen.
18289 * font.c: Don't assume string length fits in int.
18290 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
18291 Use ptrdiff_t, not int.
18292 (font_intern_prop): Don't assume string length fits in int.
18293 Don't assume integer property fits in fixnum.
18294 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
18296 * filelock.c: Fix some buffer overrun and integer overflow issues.
18297 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
18298 Reformulate so as not to need the command string.
18299 Invoke gzip -cd rather than gunzip, as it's more portable.
18300 (lock_info_type, lock_file_1, lock_file):
18301 Don't assume pid_t and time_t fit in unsigned long.
18302 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
18303 (current_lock_owner): Prefer signed type for sizes.
18304 Use memcpy, not strncpy, where memcpy is what is really wanted.
18305 Don't assume (via atoi) that time_t and pid_t fit in int.
18306 Check for time_t and/or pid_t out of range, e.g., via a network share.
18307 Don't alloca where an auto var works fine.
18309 * fileio.c: Fix some integer overflow issues.
18310 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
18311 Don't assume string length fits in int.
18312 (directory_file_name): Don't assume string length fits in long.
18313 (make_temp_name): Don't assume pid fits in int, or that its print
18314 length is less than 20.
18316 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
18318 * coding.c (make_subsidiaries): Don't assume string length fits in int.
18320 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
18322 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
18323 We prefer signed integers, even for size calculations.
18325 * emacs.c: Don't assume string length fits in 'int'.
18326 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
18327 (main): Don't invoke strlen when not needed.
18329 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
18330 (XD_DEBUG_MESSAGE): Don't waste a byte.
18332 * callproc.c (getenv_internal_1, getenv_internal)
18333 (Fgetenv_internal):
18334 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
18336 * lread.c (invalid_syntax): Omit length argument.
18337 All uses changed. This doesn't fix a bug, but it simplifies the
18338 code away from its former Hollerith-constant appearance, and it's
18339 one less 'int' to worry about when looking at integer-overflow issues.
18340 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
18342 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
18343 This didn't break anything, but it didn't help either.
18344 It's confusing to put a bogus integer in a place where the actual
18345 value does not matter.
18346 (LIST_END_P): Remove unused macro and its bogus comment.
18347 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
18349 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
18350 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
18352 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
18353 We prefer signed types, and the value cannot exceed the EMACS_INT
18354 range anyway (because otherwise the length would not be representable).
18355 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
18356 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
18357 This avoids a GCC warning when WIDE_EMACS_INT.
18359 * indent.c (sane_tab_width): New function.
18360 (current_column, scan_for_column, Findent_to, position_indentation)
18361 (compute_motion): Use it. This is just for clarity.
18362 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
18364 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
18366 * lisp.h (lint_assume): New macro.
18367 * composite.c (composition_gstring_put_cache):
18368 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
18370 * editfns.c, insdel.c:
18371 Omit unnecessary forward decls, to simplify future changes.
18373 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
18375 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
18377 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
18378 Use much-faster test for byte-length change.
18379 Don't assume string byte-length fits in 'int'.
18380 Check that character arg fits in 'int'.
18381 (mapcar1): Declare byte as byte, for clarity.
18383 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
18385 * fns.c (concat): Catch string overflow earlier.
18386 Do not rely on integer wraparound.
18388 * dispextern.h (struct it.overlay_strings_charpos)
18389 (struct it.selective): Now EMACS_INT, not int.
18390 * xdisp.c (forward_to_next_line_start)
18391 (back_to_previous_visible_line_start)
18392 (reseat_at_next_visible_line_start, next_element_from_buffer):
18393 Don't arbitrarily truncate the value of 'selective' to int.
18395 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
18397 * composite.c: Don't truncate sizes to 'int'.
18398 (composition_gstring_p, composition_reseat_it)
18399 (composition_adjust_point): Use EMACS_INT, not int.
18400 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
18401 not EMACS_UINT, for indexes.
18403 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
18405 * buffer.c: Include <verify.h>.
18406 (struct sortvec.priority, struct sortstr.priority):
18407 Now EMACS_INT, not int.
18408 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
18409 (struct sortstr.size, record_overlay_string)
18410 (struct sortstrlist.size, struct sortlist.used):
18411 Don't truncate size to int.
18412 (record_overlay_string): Check for size-calculation overflow.
18413 (init_buffer_once): Check at compile-time, not run-time.
18415 2011-06-22 Jim Meyering <meyering@redhat.com>
18417 Don't leak an XBM-image-sized buffer
18418 * image.c (xbm_load): Free the image buffer after using it.
18420 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
18423 * composite.c (find_automatic_composition): Omit needless 'return 0;'
18424 that Sun C diagnosed.
18425 * fns.c (secure_hash): Fix pointer signedness issue.
18426 * intervals.c (static_offset_intervals): New function.
18427 (offset_intervals): Use it.
18429 2011-06-21 Leo Liu <sdl.web@gmail.com>
18432 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
18435 * fns.c (secure_hash): Rename from crypto_hash_function and change
18436 the first arg to accept symbols.
18437 (Fsecure_hash): New primitive.
18438 (syms_of_fns): New symbols.
18440 2011-06-20 Deniz Dogan <deniz@dogan.se>
18442 * process.c (Fset_process_buffer): Clarify return value in
18445 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
18447 * dispnew.c (add_window_display_history): Use BVAR.
18449 * xdisp.c (debug_method_add): Use BVAR.
18450 (check_window_end, dump_glyph_matrix, dump_glyph)
18451 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
18453 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
18456 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
18457 check till after the cache is created in init_frame_faces.
18459 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
18461 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
18463 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
18465 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
18466 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
18467 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
18469 Improve buffer-overflow checking (Bug#8873).
18470 * fileio.c (Finsert_file_contents):
18471 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
18472 Remove the old (too-loose) buffer overflow checks.
18473 They weren't needed, since make_gap checks for buffer overflow.
18474 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
18475 The old code merely checked for Emacs fixnum overflow, and relied
18476 on undefined (wraparound) behavior. The new code avoids undefined
18477 behavior, and also checks for ptrdiff_t and/or size_t overflow.
18479 * editfns.c (Finsert_char): Don't dump core with very negative counts.
18480 Tune. Don't use wider integers than needed. Don't use alloca.
18481 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
18483 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
18485 * insdel.c, lisp.h (buffer_overflow): New function.
18486 (insert_from_buffer_1, replace_range, replace_range_2):
18487 * insdel.c (make_gap_larger):
18488 * editfns.c (Finsert_char):
18489 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
18491 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
18493 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
18495 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
18497 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
18498 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
18500 * fileio.c: Don't assume EMACS_INT fits in off_t.
18501 (emacs_lseek): New static function.
18502 (Finsert_file_contents, Fwrite_region): Use it.
18503 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
18505 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
18507 * fns.c: Don't overflow int when computing a list length.
18508 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
18509 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
18510 truncation on 64-bit hosts. Check for QUIT every
18511 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
18512 faster and is responsive enough.
18513 (Flength): Report an error instead of overflowing an integer.
18514 (Fsafe_length): Return a float if the value is not representable
18515 as a fixnum. This shouldn't happen except in contrived situations.
18516 (Fnthcdr, Fsort): Don't assume list length fits in int.
18517 (Fcopy_sequence): Don't assume vector length fits in int.
18519 * alloc.c: Check that resized vectors' lengths fit in fixnums.
18520 (header_size, word_size): New constants.
18521 (allocate_vectorlike): Don't check size overflow here.
18522 (allocate_vector): Check it here instead, since this is the only
18523 caller of allocate_vectorlike that could cause overflow.
18524 Check that the new vector's length is representable as a fixnum.
18526 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
18527 The previous code was bogus. For example, next_almost_prime (32)
18528 returned 39, which is undesirable as it is a multiple of 3; and
18529 next_almost_prime (24) returned 25, which is a multiple of 5 so
18530 why was the code bothering to check for multiples of 7?
18532 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
18534 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
18536 Variadic C functions now count arguments with ptrdiff_t.
18537 This partly undoes my 2011-03-30 change, which replaced int with size_t.
18538 Back then I didn't know that the Emacs coding style prefers signed int.
18539 Also, in the meantime I found a few more instances where arguments
18540 were being counted with int, which may truncate counts on 64-bit
18541 machines, or EMACS_INT, which may be unnecessarily wide.
18542 * lisp.h (struct Lisp_Subr.function.aMANY)
18543 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
18544 Arg counts are now ptrdiff_t, not size_t.
18545 All variadic functions and their callers changed accordingly.
18546 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
18547 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
18548 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
18549 * callint.c (Fcall_interactively): Check arg count for overflow,
18550 to avoid potential buffer overrun. Use signed char, not 'int',
18551 for 'varies' array, so that we needn't bother to check its size
18552 calculation for overflow.
18553 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
18554 * eval.c (apply_lambda):
18555 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
18556 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
18557 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
18559 * callint.c (Fcall_interactively): Don't use index var as event count.
18561 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
18562 * mem-limits.h (SIZE): Remove; no longer used.
18564 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
18566 Remove unnecessary casts.
18567 * xterm.c (x_term_init):
18568 * xfns.c (x_set_border_pixel):
18569 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
18570 These aren't needed now that we assume ANSI C.
18572 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
18573 It's more likely to cause problems (due to unsigned overflow)
18576 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
18578 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
18580 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
18582 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
18584 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
18586 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
18588 GLYPH_CODE_FACE returns EMACS_INT, not int.
18589 * dispextern.h (merge_faces):
18590 * xfaces.c (merge_faces):
18591 * xdisp.c (get_next_display_element, next_element_from_display_vector):
18592 Don't assume EMACS_INT fits in int.
18594 * character.h (CHAR_VALID_P): Remove unused parameter.
18595 * fontset.c, lisp.h, xdisp.c: All uses changed.
18597 * editfns.c (Ftranslate_region_internal): Omit redundant test.
18599 * fns.c (concat): Minor tuning based on overflow analysis.
18600 This doesn't fix any bugs. Use int to hold character, instead
18601 of constantly refetching from Emacs object. Use XFASTINT, not
18602 XINT, for value known to be a character. Don't bother comparing
18603 a single byte to 0400, as it's always less.
18605 * floatfns.c (Fexpt):
18606 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
18608 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
18611 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
18613 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
18614 Without this fix, on a 64-bit host (aset S 0 4294967386) would
18615 incorrectly succeed when S was a string, because 4294967386 was
18616 truncated before it was used.
18618 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
18619 Otherwise, an out-of-range integer could cause undefined behavior
18622 * composite.c: Use int, not EMACS_INT, for characters.
18623 (fill_gstring_body, composition_compute_stop_pos): Use int, not
18624 EMACS_INT, for values that are known to be in character range.
18625 This doesn't fix any bugs but is the usual style inside Emacs and
18626 may generate better code on 32-bit machines.
18628 Make sure a 64-bit char is never passed to ENCODE_CHAR.
18629 This is for reasons similar to the recent CHAR_STRING fix.
18630 * charset.c (Fencode_char): Check that character arg is actually
18631 a character. Pass an int to ENCODE_CHAR.
18632 * charset.h (ENCODE_CHAR): Verify that the character argument is no
18633 wider than 'int', as a compile-time check to prevent future regressions
18636 * character.c (char_string): Remove unnecessary casts.
18638 Make sure a 64-bit char is never passed to CHAR_STRING.
18639 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
18640 by silently ignoring the top 32 bits, allowing some values
18641 that were far too large to be valid characters.
18642 * character.h: Include <verify.h>.
18643 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
18644 arguments are no wider than unsigned, as a compile-time check
18645 to prevent future regressions in this area.
18647 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
18648 (Fsubst_char_in_region):
18650 * xdisp.c (decode_mode_spec_coding):
18651 Adjust to CHAR_STRING's new requirement.
18652 * editfns.c (Finsert_char, Fsubst_char_in_region):
18653 * fns.c (concat): Check that character args are actually
18654 characters. Without this test, these functions did the wrong
18655 thing with wildly out-of-range values on 64-bit hosts.
18657 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
18658 These casts should not be needed on 32-bit hosts, either.
18659 * keyboard.c (read_char):
18660 * lread.c (Fload): Remove casts to unsigned.
18662 * lisp.h (UNSIGNED_CMP): New macro.
18663 This fixes comparison bugs on 64-bit hosts.
18664 (ASCII_CHAR_P): Use it.
18665 * casefiddle.c (casify_object):
18666 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
18667 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
18668 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
18669 * dispextern.h (FACE_FROM_ID):
18670 * keyboard.c (read_char): Use UNSIGNED_CMP.
18672 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
18673 not to EMACS_INT, to avoid GCC warning.
18675 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
18677 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
18678 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and

19314 instead of using explicit *_CHAR codes.
19315 (bidi_resolve_explicit, bidi_resolve_weak):

19324 (bidi_level_of_next_char): Don't try to lookup the cache for the
19325 next/previous character if nothing is cached there yet, or if we
19326 were just reseat()'ed to a new position.
19328 * xdisp.c (set_cursor_from_row): Set start and stop points
19329 according to the row's direction when priming the loop that looks
19330 for the glyph on which to display cursor.

19332 (display_prop_intangible_p): Reimplement to call
19333 handle_display_spec instead of single_display_spec_intangible_p.
19334 Accept 3 additional arguments needed by handle_display_spec.
19335 This fixes incorrect cursor motion across display property with complex
19336 values: lists, `(when COND...)' forms, etc.

19338 lists with the argument STRING its top-level element.
19339 (display_prop_string_p): Fix the condition for processing a

19342 last portion of handle_display_prop.
19343 (compute_display_string_pos): Accept additional argument
19344 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
19345 value of a `display' property is a "replacing spec".
19346 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
19347 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
19348 the display property, but just return a value indicating whether
19349 the display property will replace the characters it covers.
19350 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
19351 frame_window_p members of struct bidi_it.
19352 (compute_display_string_pos, compute_display_string_end):

19358 * keyboard.c (adjust_point_for_property): Adjust the call to
19359 display_prop_intangible_p to its new signature.

19375 All callers changed. (Bug#8762)
19377 * gnutls.c: Use Emacs's memory allocators.
19378 Without this change, the gnutls library would invoke malloc etc.
19379 directly, which causes problems on non-SYNC_INPUT hosts, and which
19380 runs afoul of improving memory_full behavior. (Bug#8761)
19381 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
19382 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
19383 xfree instead of the default malloc, realloc, free.
19384 (Fgnutls_boot): No need to check for memory allocation failure,
19385 since xmalloc does that for us.
19387 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)

19407 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
19408 for hashes and hash indexes, instead of 'unsigned' and 'int'.
19409 * alloc.c (allocate_vectorlike):
19410 Check for overflow in vector size calculations.
19411 * ccl.c (ccl_driver):
19412 Check for overflow when converting EMACS_INT to int.

19414 need to be updated by these changes.
19415 * fns.c (make_hash_table, maybe_resize_hash_table):
19416 Check for integer overflow with large hash tables.
19417 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
19418 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
19419 (SXHASH_REDUCE): New macro.
19420 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
19421 Use it instead of discarding useful hash info with large hash values.
19422 (sxhash_float): New function.
19423 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
19424 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
19425 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
19426 Rewrite to use FIXNUM_BITS, as this simplifies things.
19427 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
19428 Adjust signatures to match updated version of code.
19429 (consing_since_gc): Now EMACS_INT, since a single hash table can
19430 use more than INT_MAX bytes.

19479 Make it possible to run ./temacs.
19481 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
19482 syms_of_callproc does the same thing. Remove test for
19483 "initialized", do it in the caller.
19484 * emacs.c (main): Avoid calling set_initial_environment when dumping.

19543 * fns.c (to_uchar): Define.
19544 (crypto_hash_function): Use it to convert some newly-signed

19551 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
19553 Integer overflow fixes.
19555 * dbusbind.c: Serial number integer overflow fixes.
19556 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
19557 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
19558 to hold a serial number that is too large for a fixnum.
19559 (Fdbus_method_return_internal, Fdbus_method_error_internal):
19560 Check for serial numbers out of range. Decode any serial number
19561 that was so large that it became a float. (Bug#8722)
19563 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
19564 (Fdbus_call_method, Fdbus_call_method_asynchronously):
19565 Use XFASTINT rather than XUINT when numbers are nonnegative.
19566 (xd_append_arg, Fdbus_method_return_internal):
19567 (Fdbus_method_error_internal): Likewise. Also, for unsigned
19568 arguments, check that Lisp number is nonnegative, rather than
19569 silently wrapping negative numbers around. (Bug#8722)
19570 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
19573 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
19575 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
19577 ccl: Add integer overflow checks.
19578 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
19579 (IN_INT_RANGE): New macros.
19580 (ccl_driver): Use them to check for integer overflow when
19581 decoding a CCL program. Many of the new checks are whether XINT (x)
19582 fits in int; it doesn't always, on 64-bit hosts. The new version
19583 doesn't catch all possible integer overflows, but it's an
19584 improvement. (Bug#8719)
19586 * alloc.c (make_event_array): Use XINT, not XUINT.
19587 There's no need for unsigned here.
19589 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
19590 This follows up to the 2011-05-06 change that substituted uintptr_t
19591 for EMACS_INT. This case wasn't caught back then.
19593 Rework Fformat to avoid integer overflow issues.
19594 * editfns.c: Include <float.h> unconditionally, as it's everywhere
19595 now (part of C89). Include <verify.h>.
19596 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
19597 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
19598 (Fformat): Avoid the prepass trying to compute sizes; it was only
19599 approximate and thus did not catch overflow reliably. Instead, walk
19600 through the format just once, formatting and computing sizes as we go,
19601 checking for integer overflow at every step, and allocating a larger
19602 buffer as needed. Keep track separately whether the format is
19603 multibyte. Keep only the most-recently calculated precision, rather
19604 than them all. Record whether each argument has been converted to
19605 string. Use EMACS_INT, not int, for byte and char and arg counts.
19606 Support field widths and precisions larger than INT_MAX. Avoid
19607 sprintf's undefined behavior with conversion specifications such as %#d
19608 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
19609 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
19610 formatting out-of-range floating point numbers with int
19611 formats. (Bug#8668)
19613 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
19615 * data.c: Avoid integer truncation in expressions involving floats.
19616 * data.c: Include <intprops.h>.
19617 (arith_driver): When there's an integer overflow in an expression
19618 involving floating point, convert the integers to floating point
19619 so that the resulting value does not suffer from catastrophic
19620 integer truncation. For example, on a 64-bit host (* 4
19621 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
19622 Do not rely on undefined behavior after integer overflow.
19624 merge count_size_as_multibyte, parse_str_to_multibyte
19625 * character.c, character.h (count_size_as_multibyte):
19626 Rename from parse_str_to_multibyte; all uses changed.
19627 Check for integer overflow.
19628 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
19629 since it's now a duplicate of the other. This is more of
19630 a character than a buffer op, so better that it's in character.c.
19631 * fns.c, print.c: Adjust to above changes.
19633 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
19635 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
19637 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
19639 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
19640 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
19641 (x_clipboard_manager_save): Now static.
19642 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
19644 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
19645 (crypto_hash_function): Now static.
19646 Fix pointer signedness problems. Avoid unnecessary initializations.
19648 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
19650 * termhooks.h (Vselection_alist): Make it terminal-local.
19652 * terminal.c (create_terminal): Initialize it.
19654 * xselect.c: Support for clipboard managers.
19655 (Vselection_alist): Move to termhooks.h as terminal-local var.
19656 (LOCAL_SELECTION): New macro.
19657 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
19658 (symbol_to_x_atom): Remove gratuitous arg.
19659 (x_handle_selection_request, lisp_data_to_selection_data)
19660 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
19661 (x_own_selection, x_get_local_selection, x_convert_selection):
19662 New arg, specifying work frame. Use terminal-local Vselection_alist.
19663 (some_frame_on_display): Delete unused function.
19664 (Fx_own_selection_internal, Fx_get_selection_internal)
19665 (Fx_disown_selection_internal, Fx_selection_owner_p)
19666 (Fx_selection_exists_p): New optional frame arg.
19667 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
19668 (x_handle_selection_clear): Don't treat other terminals with the
19669 same keyboard specially. Use the terminal-local Vselection_alist.
19670 (x_clear_frame_selections): Use Frun_hook_with_args.
19672 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
19674 * xterm.h: Add support for those atoms.
19676 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
19678 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
19679 (converted_selections, conversion_fail_tag): New global variables.
19680 (x_selection_request_lisp_error): Free the above.
19681 (x_get_local_selection): Remove unnecessary code.
19682 (x_reply_selection_request): Args changed; handle arbitrary array
19683 of converted selections stored in converted_selections.
19684 Separate the XChangeProperty and SelectionNotify steps.
19685 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
19686 (x_convert_selection): New function.
19687 (x_handle_selection_event): Simplify.
19688 (x_get_foreign_selection): Don't ignore incoming requests while
19689 waiting for an answer; this will fail when we implement
19690 SAVE_TARGETS, and seems unnecessary anyway.
19691 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
19692 (Vx_sent_selection_functions): Doc fix.
19694 2011-05-26 Leo Liu <sdl.web@gmail.com>
19696 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
19698 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19700 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
19702 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
19703 for fringe update if it has periodic bitmap.
19704 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
19705 and fringe_bitmap_periodic_p.
19707 * fringe.c (get_fringe_bitmap_data): New function.
19708 (draw_fringe_bitmap_1, update_window_fringes): Use it.
19709 (update_window_fringes): Record periodicity of fringe bitmap in glyph
19710 row. Mark glyph row for fringe update if periodicity changed.
19712 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
19713 for fringe update unless it has periodic bitmap.
19715 2011-05-25 Kenichi Handa <handa@m17n.org>
19717 * xdisp.c (get_next_display_element): Set correct it->face_id for
19718 a static composition.
19720 2011-05-24 Leo Liu <sdl.web@gmail.com>
19723 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
19725 * fns.c (crypto_hash_function, Fsha1): New function.
19726 (Fmd5): Use crypto_hash_function.
19727 (syms_of_fns): Add Ssha1.
19729 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
19731 * gnutls.c: Remove unused macros.
19732 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
19733 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
19734 Remove macros that are defined and never used.
19735 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
19737 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
19739 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
19740 (Fx_get_selection_internal): Minor cleanup.
19741 (Fx_own_selection_internal): Rename arguments for consistency with
19744 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
19746 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
19748 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
19750 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
19752 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19754 * dispnew.c (scrolling_window): Don't exclude the case that the
19755 last enabled row in the desired matrix touches the bottom boundary.
19757 2011-05-21 Glenn Morris <rgm@gnu.org>
19759 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
19760 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
19761 and add some more files.
19763 2011-05-20 Eli Zaretskii <eliz@gnu.org>
19765 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
19766 report_file_error introduced by the change from 2011-05-07.
19768 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
19770 * systime.h (Time): Define only if emacs is defined.
19771 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
19772 where the include path doesn't have X11/X.h by default. See
19773 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
19775 2011-05-20 Kenichi Handa <handa@m17n.org>
19777 * composite.c (find_automatic_composition): Fix previous change.
19779 2011-05-20 Glenn Morris <rgm@gnu.org>
19781 * lisp.mk: New file, split from Makefile.in.
19782 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
19783 (shortlisp): Remove.
19784 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
19786 2011-05-19 Glenn Morris <rgm@gnu.org>
19788 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
19789 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
19790 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
19791 (lisp): Set the order to that of loadup.el.
19792 (shortlisp): Make it a copy of $lisp.
19793 (SOME_MACHINE_LISP): Remove.
19794 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
19795 Use just $shortlisp, not $SOME_MACHINE_LISP too.
19797 2011-05-18 Kenichi Handa <handa@m17n.org>
19799 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
19800 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
19801 (find_automatic_composition): Mostly rewrite for efficiency.
19803 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
19805 * makefile.w32-in: Update dependencies.
19807 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
19809 * menu.c: Include limits.h (fixes the MS-Windows build broken by
19810 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
19812 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
19814 Fix some integer overflow issues, such as string length overflow.
19816 * insdel.c (count_size_as_multibyte): Check for string overflow.
19818 * character.c (lisp_string_width): Check for string overflow.
19819 Use EMACS_INT, not int, for string indexes and lengths; in
19820 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
19821 the resulting string length overflows an EMACS_INT; instead,
19822 report a string overflow if no precision given. When checking for
19823 precision exhaustion, use a check that cannot possibly have
19824 integer overflow. (Bug#8675)
19825 * character.h (lisp_string_width): Adjust to new signature.
19827 * alloc.c (string_overflow): New function.
19828 (Fmake_string): Use it. This doesn't change behavior, but saves
19829 a few bytes and will simplify future changes.
19830 * character.c (string_escape_byte8): Likewise.
19831 * lisp.h (string_overflow): New decl.
19833 Fixups, following up to the user-interface timestamp change.
19834 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
19835 for UI timestamps, instead of unsigned long.
19836 * msdos.c (mouse_get_pos): Likewise.
19837 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
19838 * w32gui.h (Time): Define by including "systime.h" rather than by
19839 declaring it ourselves. (Bug#8664)
19841 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
19842 * image.c (clear_image_cache): Likewise.
19844 * term.c (term_mouse_position): Don't assume time_t wraparound.
19846 Be more systematic about user-interface timestamps.
19847 Before, the code sometimes used 'Time', sometimes 'unsigned long',
19848 and sometimes 'EMACS_UINT', to represent these timestamps.
19849 This change causes it to use 'Time' uniformly, as that's what X uses.
19850 This makes the code easier to follow, and makes it easier to catch
19851 integer overflow bugs such as Bug#8664.
19852 * frame.c (Fmouse_position, Fmouse_pixel_position):
19853 Use Time, not unsigned long, for user-interface timestamps.
19854 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
19855 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
19856 * keyboard.h (last_event_timestamp): Likewise.
19857 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
19858 * menu.h (xmenu_show): Likewise.
19859 * term.c (term_mouse_position): Likewise.
19860 * termhooks.h (struct input_event.timestamp): Likewise.
19861 (struct terminal.mouse_position_hook): Likewise.
19862 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
19863 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
19864 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
19865 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
19866 what it was before.
19867 * menu.h, termhooks.h: Include "systime.h", for Time.
19869 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
19870 Don't assume that the difference between two unsigned long values
19871 can fit into an integer. At this point, we know button_down_time
19872 <= event->timestamp, so the difference must be nonnegative, so
19873 there's no need to cast the result if double-click-time is
19874 nonnegative, as it should be; check that it's nonnegative, just in
19875 case. This bug is triggered when events are more than 2**31 ms
19876 apart (about 25 days). (Bug#8664)
19878 * xselect.c (last_event_timestamp): Remove duplicate decl.
19879 (x_own_selection): Remove needless cast to unsigned long.
19881 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
19882 that always fit in int. Use a sentinel instead of a counter, to
19883 avoid a temp and to allay GCC's concerns about possible int overflow.
19884 * frame.h (struct frame): Use int for menu_bar_items_used
19885 instead of EMACS_INT, since it always fits in int.
19887 * menu.c (grow_menu_items): Check for int overflow.
19889 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
19891 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
19892 Before, the code was not consistent. These values cannot exceed
19893 2**31 - 1 so there's no need to make them unsigned.
19894 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
19895 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
19896 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
19898 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
19900 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
19901 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
19902 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
19903 presumably because the widths might not match.
19905 * window.c (size_window): Avoid needless test at loop start.
19907 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
19909 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
19911 2011-05-12 Drew Adams <drew.adams@oracle.com>
19913 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
19915 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19917 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
19918 `width' to `bar_area_x' and `bar_area_width', respectively.
19919 (x_scroll_run): Take account of fringe background extension.
19921 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
19922 Rename local vars `left' and `width' to `bar_area_x' and
19923 `bar_area_width', respectively.
19924 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
19925 background extension.
19927 2011-05-10 Jim Meyering <meyering@redhat.com>
19929 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
19931 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
19933 * image.c (Finit_image_library): Return t for built-in image types,
19934 like pbm and xbm. (Bug#8640)
19936 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
19938 * w32menu.c (set_frame_menubar): Fix submenu allocation.
19940 2011-05-07 Eli Zaretskii <eliz@gnu.org>
19942 * w32console.c (Fset_screen_color): Doc fix.
19943 (Fget_screen_color): New function.
19944 (syms_of_ntterm): Defsubr it.
19946 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
19947 unlink the temporary file if Fcall_process didn't create it in the
19949 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
19950 child process will be redirected to a file specified with `:file'.
19951 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
19952 cue to call_process_cleanup not to close that handle.
19954 2011-05-07 Ben Key <bkey76@gmail.com>
19956 * makefile.w32-in: The bootstrap-temacs rule now makes use of
19957 one of two shell specific rules, either bootstrap-temacs-CMD or
19958 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
19959 to the previous implementation of the bootstrap-temacs rule.
19960 The bootstrap-temacs-CMD rule is similar to the previous
19961 implementation of the bootstrap-temacs rule except that it
19962 makes use of the ESC_CFLAGS variable instead of the CFLAGS
19965 These changes, along with some changes to nt/configure.bat,
19966 nt/gmake.defs, and nt/nmake.defs, are required to extend my
19967 earlier fix to add support for --cflags and --ldflags options
19968 that include quotes so that it works whether make uses cmd or
19971 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
19973 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
19974 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
19976 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
19977 a string. Handle both cases.
19978 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
19979 (Fdbus_register_method): Use Qinvalid_function.
19981 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
19983 * makefile.w32-in: Update dependencies.
19984 (LISP_H): Add inttypes.h and stdin.h.
19985 (PROCESS_H): Add unistd.h.
19987 2011-05-06 Eli Zaretskii <eliz@gnu.org>
19989 * lread.c: Include limits.h (fixes the MS-Windows build broken by
19990 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
19992 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
19994 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
19996 * term.c (vfatal): Remove stray call to va_end.
19997 It's not needed and the C Standard doesn't allow it here anyway.
19999 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
20000 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
20002 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
20005 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
20007 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
20009 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
20011 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
20013 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
20015 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
20016 * charset.c (Fdefine_charset_internal): Don't initialize
20017 charset.code_space[15]. The value was garbage, on hosts with
20018 32-bit int (Bug#8600).
20020 * lread.c (read_integer): Be more consistent with string-to-number.
20021 Use string_to_number to do the actual conversion; this avoids
20022 rounding errors and fixes some other screwups. Without this fix,
20023 for example, #x1fffffffffffffff was misread as -2305843009213693952.
20024 (digit_to_number): Move earlier, for benefit of read_integer.
20025 Return -1 if the digit is out of range for the base, -2 if it is
20026 not a digit in any supported base. (Bug#8602)
20028 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
20030 * dispnew.c (scrolling_window): Return 1 if we scrolled,
20031 to match comment at start of function. This also removes a
20032 GCC warning about overflow in a 32+64-bit port.
20034 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
20036 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
20037 Reported by Stefan Monnier in
20038 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
20039 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
20040 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
20042 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
20043 (EMACS_UINTPTR): Likewise, with uintptr_t.
20045 * lisp.h: Prefer 64-bit EMACS_INT if available.
20046 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
20047 on 32-bit hosts that have 64-bit int, so that they can access
20049 However, temporarily disable this change unless the temporary
20050 symbol WIDE_EMACS_INT is defined.
20052 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
20054 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
20055 This removes an assumption that EMACS_INT and long are the same
20056 width as pointers. The assumption is true for Emacs porting targets
20057 now, but we want to make other targets possible.
20058 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
20059 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
20060 In the rest of the code, change types of integers that hold casted
20061 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
20062 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
20063 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
20064 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
20065 No need to cast type when ORing.
20066 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
20067 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
20068 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
20069 assume EMACS_INT is the same width as char *.
20070 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
20071 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
20072 Remove no-longer-needed casts.
20073 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
20074 (xg_tool_bar_help_callback, xg_make_tool_item):
20075 Use EMACS_INTPTR to hold an integer
20076 that will be cast to void *; this can avoid a GCC warning
20077 if EMACS_INT is not the same width as void *.
20078 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
20079 * xdisp.c (display_echo_area_1, resize_mini_window_1):
20080 (current_message_1, set_message_1):
20081 Use a local to convert to proper width without a cast.
20082 * xmenu.c (dialog_selection_callback): Likewise.
20084 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
20085 Also, don't assume VALBITS / RAND_BITS is less than 5,
20086 and don't rely on undefined behavior when shifting a 1 left into
20088 * lisp.h (get_random): Change signature to match.
20090 * lread.c (hash_string): Use size_t, not int, for hash computation.
20091 Normally we prefer signed values; but hashing is special, because
20092 it's better to use unsigned division on hash table sizes so that
20093 the remainder is nonnegative. Also, size_t is the natural width
20094 for hashing into memory. The previous code used 'int', which doesn't
20095 retain enough info to hash well into very large tables.
20096 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
20098 * dbusbind.c: Don't possibly lose pointer info when converting.
20099 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
20100 Use XPNTR rather than XHASH, so that the high-order bits of
20101 the pointer aren't lost when converting through void *.
20103 * eval.c (Fautoload): Don't double-shift a pointer.
20105 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
20107 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
20109 * gnutls.c (DEF_GNUTLS_FN):
20110 * image.c (DEF_IMGLIB_FN): Make function pointers static.
20112 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
20114 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
20117 2011-05-05 Eli Zaretskii <eliz@gnu.org>
20119 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
20120 New version that can reserve upto 2GB of heap space.
20122 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
20124 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
20126 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
20128 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
20129 `gnutls_certificate_set_x509_key_file'.
20131 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
20133 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
20134 Update dependencies.
20136 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
20138 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
20139 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
20140 Remove unused parameter `fildes'.
20141 * process.c (read_process_output, send_process): Don't pass it.
20143 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
20145 Fix previous change: the library cache is defined in w32.c.
20146 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
20147 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
20149 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
20151 Implement dynamic loading of GnuTLS on Windows.
20153 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
20154 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
20155 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
20158 * gnutls.c (Qgnutls_dll): Define.
20159 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
20160 (gnutls_*): Declare function pointers.
20161 (init_gnutls_functions): New function to initialize function pointers.

20163 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
20164 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
20165 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
20166 (emacs_gnutls_write, emacs_gnutls_read)
20167 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
20168 (Fgnutls_available_p): New function.
20169 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.

20179 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
20181 * w32.c (QCloaded_from, Vlibrary_cache): Define.
20182 (w32_delayed_load): Move from image.c. When loading a library, record
20183 its filename in the :loaded-from property of the library id.
20184 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
20185 Initialize and staticpro them.
20186 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
20188 * process.c: Include lisp.h before w32.h, not after.
20189 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
20190 instead of gnutls_record_check_pending.
20192 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
20194 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
20196 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
20197 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
20200 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
20202 * xterm.c (x_set_frame_alpha): Do not set property on anything
20203 else than FRAME_X_OUTER_WINDOW (Bug#8608).
20205 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
20207 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
20209 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
20211 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
20212 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)

20221 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
20223 * callproc.c: Indentation fixup.
20225 * sysdep.c (wait_for_termination_1): Make static.
20226 (wait_for_termination, interruptible_wait_for_termination):
20227 Move after wait_for_termination_1.
20229 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
20231 * sysdep.c (interruptible_wait_for_termination): New function
20232 which is like wait_for_termination, but allows keyboard
20235 * callproc.c (Fcall_process): Add (:file "file") as an option for
20237 (Fcall_process_region): Ditto.
20239 2011-04-30 Eli Zaretskii <eliz@gnu.org>
20241 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
20242 rather than `XVECTOR (FOO)->size'.
20244 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
20245 inttypes.h, as a gnulib replacement is used if it not available in
20248 2011-04-21 Eli Zaretskii <eliz@gnu.org>
20250 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
20251 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
20252 of MOST_POSITIVE_FIXNUM. (Bug#8528)
20254 * coding.c (coding_alloc_by_realloc): Error out if destination
20255 will grow beyond MOST_POSITIVE_FIXNUM.
20256 (decode_coding_emacs_mule): Abort if there isn't enough place in
20257 charbuf for the composition carryover bytes. Reserve an extra
20258 space for up to 2 characters produced in a loop.
20259 (decode_coding_iso_2022): Abort if there isn't enough place in
20260 charbuf for the composition carryover bytes.
20262 2011-04-21 Eli Zaretskii <eliz@gnu.org>
20264 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
20265 aborting when %lld or %lll format is passed.
20266 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
20267 %llo or %llx format is passed. (Bug#8545)
20269 * window.c (window_scroll_line_based): Use a marker instead of
20270 simple variables to record original value of point. (Bug#7952)
20272 * doprnt.c (doprnt): Fix the case where a multibyte sequence
20273 produced by %s or %c overflows available buffer space. (Bug#8545)
20275 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
20277 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
20278 (SIZE_MAX): Move defn after all includes, as they might #define it.
20280 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
20282 * w32.c (init_environment): Warn about defaulting HOME to C:\.
20284 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
20286 * keyboard.c (Qdelayed_warnings_hook): Define.
20287 (command_loop_1): Run `delayed-warnings-hook'

20292 2011-04-28 Eli Zaretskii <eliz@gnu.org>
20294 * doprnt.c (doprnt): Don't return value smaller than the buffer
20295 size if the message was truncated. (Bug#8545).
20297 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
20299 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
20300 (Fx_window_property): #if-0 the whole functions, not just the bodies.
20302 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
20304 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
20306 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
20308 * makefile.w32-in: Update dependencies.
20310 2011-04-27 Eli Zaretskii <eliz@gnu.org>
20312 Improve `doprnt' and its usage. (Bug#8545)
20313 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
20314 `format_end'. Remove support for %l as a conversion specifier.
20315 Don't use xrealloc. Improve diagnostics when the %l size modifier
20316 is used. Update the commentary.
20318 * eval.c (verror): Simplify calculation of size_t.
20320 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
20323 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
20325 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
20328 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
20330 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
20331 This makes this file independent of the recent pseudovector change.
20333 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
20335 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
20337 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
20338 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
20339 Remove unused local.
20340 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
20342 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
20343 GCC 4.6.0 optimizes based on type-based alias analysis.
20344 For example, if b is of type struct buffer * and v of type struct
20345 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
20346 != &v->size, and therefore "v->size = 1; b->size = 2; return
20347 v->size;" must therefore return 1. This assumption is incorrect
20348 for Emacs, since it type-puns struct Lisp_Vector * with many other
20349 types. To fix this problem, this patch adds a new type struct
20350 vectorlike_header that documents the constraints on layout of vectors
20351 and pseudovectors, and helps optimizing compilers not get fooled
20352 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
20353 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
20354 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
20356 (XSETPVECTYPE): Rewrite in terms of new macro.
20357 (XSETPVECTYPESIZE): New macro, specifying both type and size.
20358 This is a bit clearer, and further avoids the possibility of
20359 undesirable aliasing.
20360 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
20361 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
20362 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
20363 since Lisp_Subr is a special case (no "next" field).
20364 (ASIZE): Now uses header.size rather than size.
20365 All previous uses of XVECTOR (foo)->size replaced to use this macro,
20366 to avoid the hassle of writing XVECTOR (foo)->header.size.
20367 (struct vectorlike_header): New type.
20368 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
20369 object, to help avoid aliasing.
20370 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
20371 (SUBRP): Likewise, since Lisp_Subr is a special case.
20372 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
20373 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
20374 (struct Lisp_Hash_Table): Combine first two members into a single
20375 struct vectorlike_header member. All uses of "size" and "next" members
20376 changed to be "header.size" and "header.next".
20377 * buffer.h (struct buffer): Likewise.
20378 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
20379 * frame.h (struct frame): Likewise.
20380 * process.h (struct Lisp_Process): Likewise.
20381 * termhooks.h (struct terminal): Likewise.
20382 * window.c (struct save_window_data, struct saved_window): Likewise.
20383 * window.h (struct window): Likewise.
20384 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
20385 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
20386 * buffer.c (init_buffer_once): Likewise.
20387 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
20389 * process.c (Fformat_network_address): Use local var for size,
20392 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
20394 Make the Lisp reader and string-to-float more consistent (Bug#8525)
20395 * data.c (atof): Remove decl; no longer used or needed.
20396 (digit_to_number): Move to lread.c.
20397 (Fstring_to_number): Use new string_to_number function, to be
20398 consistent with how the Lisp reader treats infinities and NaNs.
20399 Do not assume that floating-point numbers represent EMACS_INT
20400 without losing information; this is not true on most 64-bit hosts.
20401 Avoid double-rounding errors, by insisting on integers when
20402 parsing non-base-10 numbers, as the documentation specifies.
20403 * lisp.h (string_to_number): New decl, replacing ...
20404 (isfloat_string): Remove.
20405 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
20406 (read1): Do not accept +. and -. as integers; this
20407 appears to have been a coding error. Similarly, do not accept
20408 strings like +-1e0 as floating point numbers. Do not report
20409 overflow for integer overflows unless the base is not 10 which
20410 means we have no simple and reliable way to continue.
20411 Break out the floating-point parsing into a new
20412 function string_to_number, so that Fstring_to_number parses
20413 floating point numbers consistently with the Lisp reader.
20414 (digit_to_number): Move here from data.c. Make it static inline.
20415 (E_CHAR, EXP_INT): Remove, replacing with ...
20416 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
20417 (string_to_number): New function, replacing isfloat_string.
20418 This function checks for valid syntax and produces the resulting
20419 Lisp float number too. Rework it so that string-to-number
20420 no longer mishandles examples like "1.0e+". Use strtoumax,
20421 so that overflow for non-base-10 numbers is reported only when
20422 there's no portable and simple way to convert to floating point.
20424 * textprop.c (set_text_properties_1): Rewrite for clarity,
20425 and to avoid GCC warning about integer overflow.
20427 * intervals.h (struct interval): Use EMACS_INT for members
20428 where EMACS_UINT might cause problems. See
20429 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
20430 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
20431 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
20433 (offset_intervals): Tell GCC not to worry about length overflow
20434 when negating a negative length.
20436 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
20437 (overrun_check_free): Likewise.
20439 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
20440 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
20443 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
20444 (gnutls_make_error): Rename local to avoid shadowing.
20445 (gnutls_emacs_global_deinit): ifdef out; not used.
20446 (Fgnutls_boot): Use const for pointer to readonly storage.
20447 Comment out unused local. Fix pointer signedness problems.
20449 * lread.c (openp): Don't stuff size_t into an 'int'.
20450 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
20451 about possible signed overflow.
20453 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
20454 (GDK_KEY_g): Don't define if already defined.
20455 (xg_prepare_tooltip): Avoid pointer signedness problem.
20456 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
20458 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
20459 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
20461 * xfns.c (Fx_window_property): Simplify a bit,
20462 to make a bit faster and to avoid GCC 4.6.0 warning.
20463 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
20465 * fns.c (internal_equal): Don't assume size_t fits in int.
20467 * alloc.c (compact_small_strings): Tighten assertion a little.
20469 Replace pEd with more-general pI, and fix some printf arg casts.
20470 * lisp.h (pI): New macro, generalizing old pEd macro to other
20471 conversion specifiers. For example, use "...%"pI"d..." rather
20472 than "...%"pEd"...".
20473 (pEd): Remove. All uses replaced with similar uses of pI.
20474 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
20475 * alloc.c (check_pure_size): Don't overflow by converting size to int.
20476 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
20477 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
20478 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
20479 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
20480 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
20482 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
20483 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
20484 * print.c (safe_debug_print, print_object): Likewise.
20485 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
20487 Use pI instead of if-then-else-abort. Use %p to avoid casts,
20488 avoiding the 0 flag, which is not portable.
20489 * process.c (Fmake_network_process): Use pI to avoid cast.
20490 * region-cache.c (pp_cache): Likewise.
20491 * xdisp.c (decode_mode_spec): Likewise.
20492 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
20493 behavior on 64-bit hosts with printf arg.
20494 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
20495 (x_stop_queuing_selection_requests): Likewise.
20496 (x_get_window_property): Don't truncate byte count to an 'int'
20499 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
20500 here, since it parses constructs like leading '-' and spaces,
20501 which are not wanted; and it overflows with large numbers.
20502 Instead, simply match F[0-9]+, which is what is wanted anyway.
20504 * alloc.c: Remove unportable assumptions about struct layout.
20505 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
20506 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
20507 (allocate_vectorlike, make_pure_vector): Use the new macros,
20508 plus offsetof, to remove unportable assumptions about struct layout.
20509 These assumptions hold on all porting targets that I know of, but
20510 they are not guaranteed, they're easy to remove, and removing them
20511 makes further changes easier.
20513 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
20514 This doesn't fix a bug but makes the code clearer.
20515 (string_overrun_cookie): Now const. Use initializers that
20516 don't formally overflow signed char, to avoid warnings.
20517 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
20518 can cause Emacs to crash when string overrun checking is enabled.
20519 (allocate_buffer): Don't assume sizeof (struct buffer) is a
20520 multiple of sizeof (EMACS_INT); it need not be, if
20521 alignof(EMACS_INT) < sizeof (EMACS_INT).
20522 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
20524 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

20551 2011-04-25 Eli Zaretskii <eliz@gnu.org>
20553 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
20554 "cast to pointer from integer of different size".
20556 Improve doprnt and its use in verror. (Bug#8545)
20557 * doprnt.c (doprnt): Document the set of format control sequences
20558 supported by the function. Use SAFE_ALLOCA instead of always
20561 * eval.c (verror): Don't limit the buffer size at size_max-1, that
20562 is one byte too soon. Don't use xrealloc; instead xfree and
20565 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
20567 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
20570 * gnutls.c: Renamed global_initialized to
20571 gnutls_global_initialized. Added internals for the
20572 :verify-hostname-error, :verify-error, and :verify-flags
20573 parameters of `gnutls-boot' and documented those parameters in the
20574 docstring. Start callback support.
20575 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
20576 unless a fatal error occurred. Call gnutls_alert_send_appropriate

20650 (SIZE_MAX): New macro.
20651 (doprnt): Return a size_t value. 2nd arg is now size_t.
20652 Many local variables are now size_t instead of int or unsigned.
20653 Improve overflow protection. Support `l' modifier for integer
20654 conversions. Support %l conversion. Don't assume an EMACS_INT
20655 argument for integer conversions and for %c.
20657 * lisp.h (doprnt): Restore prototype.
20659 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
20660 $(SRC)/character.h.
20662 * Makefile.in (base_obj): Add back doprnt.o.
20664 * deps.mk (doprnt.o): Add back prerequisites.
20665 (callint.o): Depend on character.h.
20667 * eval.c (internal_lisp_condition_case): Include the handler
20668 representation in the error message.

20674 * callint.c (Fcall_interactively): When displaying error message
20675 about invalid control letter, pass the character's codepoint, not
20676 a pointer to its multibyte form. Improve display of the character
20677 in octal and display also its hex code.
20679 * character.c (char_string): Use %x to display the (unsigned)
20680 codepoint of an invalid character, to avoid displaying a bogus
20683 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
20684 `error', not SYMBOL_NAME itself.
20686 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
20687 character arguments to `error'.
20689 * charset.c (check_iso_charset_parameter): Fix incorrect argument
20690 to `error' in error message about FINAL_CHAR argument. Make sure
20691 FINAL_CHAR is a character, and use %c when it is passed as

20762 * dispextern.h (struct redisplay_interface): Rename param
20763 to avoid shadowing.
20764 * termhooks.h (struct terminal): Likewise.
20765 * xterm.c (xembed_send_message): Likewise.
20767 * insdel.c (make_gap_smaller): Define only if
20768 USE_MMAP_FOR_BUFFERS || REL_ALLOC || DOUG_LEA_MALLOC.
20770 * keyboard.c (read_char): Make a var volatile so longjmp won't clobber
20773 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,
20774 so that we aren't warned about unused symbols.
20776 * xfns.c (Fx_file_dialog): Rename local to avoid shadowing.
20778 * xdisp.c (x_produce_glyphs): Mark var as initialized (Bug#8512).

20791 if defined HAVE_MENUS && !defined USE_X_TOOLKIT && !defined USE_GTK.
20793 * xmenu.c (menu_help_callback): Pointer type fixes.

20811 compatible char. Avoid the old compiler warnings about
20812 out-of-range initializers by using, for example, '\xab' rather
20815 * xgselect.c (xgselect_initialize): Check vs interface
20816 even if ! (defined (USE_GTK) || defined (HAVE_GCONF)).

20881 * nsfont.m: Fixed bugs in ns_get_family and
20882 ns_descriptor_to_entity that were caused by using free to
20883 deallocate memory blocks that were allocated by xmalloc (via
20884 xstrdup). This caused Emacs to crash when compiled with
20885 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
20886 --enable-checking=xmallocoverrun). xfree is now used to
20887 deallocate these memory blocks.

21296 DEFUN now defines a static function. To make the function external
21297 so that it can be used in other C modules, use the new macro DEFUE.
21298 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
21299 (Finit_image_library):
21300 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
21301 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
21302 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
21303 Remove decls, since these functions are now static.
21304 (Funintern, Fget_internal_run_time): New decls, since these functions
21305 were already external.
21307 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
21308 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:
21309 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, floatfns.c:

21311 * keyboard.c, keymap.c, lread.c:
21312 * macros.c, marker.c, menu.c, minibuf.c, print.c, process.c, search.c:
21313 * syntax.c, term.c, terminal.c, textprop.c, undo.c:
21314 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
21315 Mark functions with DEFUE instead of DEFUN,
21316 if they are used in other modules.
21317 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
21318 decls for now-static functions.
21319 * buffer.h (Fdelete_overlay): Remove decl.
21320 * callproc.c (Fgetenv_internal): Mark as internal.
21321 * composite.c (Fremove_list_of_text_properties): Remove decl.

21324 * dired.c (Ffile_attributes): New forward static decl.
21325 * doc.c (Fdocumntation_property): New forward static decl.
21326 * eval.c (Ffetch_bytecode): New forward static decl.
21327 (Funintern): Remove extern decl; now in .h file where it belongs.
21328 * fileio.c (Fmake_symbolic_link): New forward static decl.
21329 * image.c (Finit_image_library): New forward static decl.
21330 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
21331 * intervals.h (Fprevious_property_change):
21332 (Fremove_list_of_text_properties): Remove decls.
21333 * keyboard.c (Fthis_command_keys): Remove decl.
21334 (Fcommand_execute): New forward static decl.

21355 2011-04-13 Eli Zaretskii <eliz@gnu.org>
21357 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
21358 when at ZV. (Bug#8487)
21360 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
21362 * charset.c (Fclear_charset_maps): Use xfree instead of free.
21364 * keyboard.c (parse_tool_bar_item): Likewise.
21365 * sound.c (sound_cleanup, alsa_close): Likewise.
21366 * termcap.c (tgetent): Likewise.
21367 * xfns.c (x_default_font_parameter): Likewise.
21368 * xsettings.c (read_and_apply_settings): Likewise.
21370 * alloc.c (overrun_check_malloc, overrun_check_realloc)
21371 (overrun_check_free): Protoize.
21373 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
21375 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
21376 since callers should never pass a negative size.
21377 Change the signature to match that of plain 'read' and 'write'; see
21378 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
21379 * lisp.h: Update prototypes of emacs_write and emacs_read.
21381 2011-04-11 Eli Zaretskii <eliz@gnu.org>
21383 * xdisp.c (redisplay_window): Don't try to determine the character
21384 position of the scroll margin if the window start point w->startp
21385 is outside the buffer's accessible region. (Bug#8468)
21387 2011-04-10 Eli Zaretskii <eliz@gnu.org>
21389 Fix write-region and its subroutines for buffers > 2GB.
21390 * fileio.c (a_write, e_write): Modify declaration of arguments and
21391 local variables to support buffers larger than 2GB.
21392 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
21394 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
21395 argument, local variables, and return value.
21397 * lisp.h: Update prototypes of emacs_write and emacs_read.
21399 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
21401 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
21403 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
21405 Fix more problems found by GCC 4.6.0's static checks.
21407 * xdisp.c (vmessage): Use a better test for character truncation.
21409 * charset.c (load_charset_map): <, not <=, for optimization,
21410 and to avoid potential problems with integer overflow.
21411 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
21412 * casetab.c (set_identity, shuffle): Likewise.
21413 * editfns.c (Fformat): Likewise.
21414 * syntax.c (skip_chars): Likewise.
21416 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
21417 This also lets GCC 4.6.0 generate slightly better loop code.
21419 * callint.c (Fcall_interactively): <, not <=, for optimization.
21420 (Fcall_interactively): Count the number of arguments produced,
21421 not the number of arguments given. This is simpler and lets GCC
21422 4.6.0 generate slightly better code.
21424 * ftfont.c: Distingish more carefully between FcChar8 and char.
21425 The previous code passed unsigned char * to a functions like
21426 strlen and xstrcasecmp that expect char *, which does not
21427 conform to the C standard.
21428 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
21429 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
21430 char * when the C standard requires it.
21432 * keyboard.c (read_char): Remove unused var.
21434 * eval.c: Port to Windows vsnprintf (Bug#8435).
21435 Include <limits.h>.
21436 (SIZE_MAX): Define if the headers do not.
21437 (verror): Do not give up if vsnprintf returns a negative count.
21438 Instead, grow the buffer. This ports to Windows vsnprintf, which
21439 does not conform to C99. Problem reported by Eli Zaretskii.
21440 Also, simplify the allocation scheme, by avoiding the need for
21441 calling realloc, and removing the ALLOCATED variable.
21443 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
21445 Remove invocations of doprnt, as Emacs now uses vsnprintf.
21446 But keep the doprint source code for now, as we might revamp it
21447 and use it again (Bug#8435).
21448 * lisp.h (doprnt): Remove.
21449 * Makefile.in (base_obj): Remove doprnt.o.
21450 * deps.mk (doprnt.o): Remove.
21452 error: Print 32- and 64-bit integers portably (Bug#8435).
21453 Without this change, on typical 64-bit hosts error ("...%d...", N)
21454 was used to print both 32- and 64-bit integers N, which relied on
21455 undefined behavior.
21456 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
21457 * lisp.h (error, verror): Mark as printf-like functions.
21458 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
21459 Report overflow in size calculations when allocating printf buffer.
21460 Do not truncate output string at its first null byte.
21461 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
21462 Truncate the output at a character boundary, since vsnprintf does not
21464 * charset.c (check_iso_charset_parameter): Convert internal
21465 character to string before calling 'error', since %c now has the
21467 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
21468 overflow when computing char to be passed to 'error'. Do not
21469 pass Lisp_Object to 'error'; pass the integer instead.
21470 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
21471 formatted with plain %d.
21473 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
21475 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
21477 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
21479 * xterm.c (x_catch_errors): Remove duplicate declaration.
21481 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
21483 * xdisp.c, lisp.h (message_nolog): Remove; unused.
21485 2011-04-10 Jim Meyering <meyering@redhat.com>
21487 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
21488 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
21489 return ssize_t not "int", and use size_t as the buffer length.
21490 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
21491 * gnutls.h: Update declarations.
21492 * process.c (read_process_output): Use ssize_t, to match.
21493 (send_process): Likewise.
21495 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
21497 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
21499 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
21501 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
21502 Use unsigned char, to match FcChar8 type definition.
21504 * xterm.c (handle_one_xevent):
21505 * xmenu.c (create_and_show_popup_menu):
21506 * xselect.c (x_decline_selection_request)
21507 (x_reply_selection_request): Avoid type-punned deref of X events.
21509 2011-04-09 Eli Zaretskii <eliz@gnu.org>
21511 Fix some uses of `int' instead of EMACS_INT.
21512 * search.c (string_match_1, fast_string_match)
21513 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
21514 (scan_buffer, find_next_newline_no_quit)
21515 (find_before_next_newline, search_command, Freplace_match)
21516 (Fmatch_data): Make some `int' variables be EMACS_INT.
21518 * xdisp.c (display_count_lines): 3rd argument and return value now
21519 EMACS_INT. All callers changed.
21520 (pint2hrstr): Last argument is now EMACS_INT.
21522 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
21523 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
21524 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
21525 (decode_coding_utf_16, decode_coding_emacs_mule)
21526 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
21527 (decode_coding_ccl, decode_coding_charset)
21528 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
21529 (decode_coding_iso_2022, decode_coding_emacs_mule)
21530 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
21531 <char_offset, last_offset>: Declare EMACS_INT.

21533 (encode_coding_emacs_mule, encode_invocation_designation)
21534 (encode_designation_at_bol, encode_coding_iso_2022)
21535 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
21536 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
21538 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
21539 (encode_invocation_designation): Last argument P_NCHARS is now
21541 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
21542 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
21544 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
21547 * ccl.c (Fccl_execute_on_string): Declare some variables
21550 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
21552 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
21554 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
21556 * process.c (Fformat_network_address): Doc fix.
21558 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
21560 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
21562 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
21564 * keyboard.c (read_char): Call Lisp function help-form-show,
21565 instead of using internal_with_output_to_temp_buffer.
21566 (Qhelp_form_show): New var.
21567 (syms_of_keyboard): Use DEFSYM macro.
21569 * print.c (internal_with_output_to_temp_buffer): Function deleted.
21571 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
21573 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
21575 * process.c (Flist_processes): Remove to Lisp.
21576 (list_processes_1): Delete.
21578 2011-04-06 Eli Zaretskii <eliz@gnu.org>
21580 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
21582 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
21584 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
21586 Fix more problems found by GCC 4.6.0's static checks.

21590 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
21592 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
21594 * xdisp.c (vmessage): Mark as a printf-like function.
21596 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.

21601 printf-like functions.
21602 (tiff_load): Add casts to remove these marks before passing them
21603 to system-supplied API.
21605 * eval.c (Fsignal): Remove excess argument to 'fatal'.
21607 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
21608 This avoids several warnings with gcc -Wstrict-overflow.
21609 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
21610 directly, rather than having caller test rule sign. This avoids
21611 some unnecessary tests.
21612 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
21613 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
21614 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
21616 * xfont.c (xfont_text_extents): Remove var that was set but not used.
21617 (xfont_open): Avoid unnecessary tests.
21619 * composite.c (composition_gstring_put_cache): Use unsigned integer.
21621 * composite.h, composite.c (composition_gstring_put_cache):
21622 Use EMACS_INT, not int, for length.

21628 by using the new macro.
21630 * textprop.c (set_text_properties_1): Change while to do-while,
21631 since the condition is always true at first.
21633 * intervals.c (graft_intervals_into_buffer): Mark var as used.
21634 (interval_deletion_adjustment): Return unsigned value.
21637 * process.c (list_processes_1, create_pty, read_process_output):

21647 (update_syntax_table): Use unsigned instead of int.
21649 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
21650 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
21651 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
21653 * print.c (print_error_message): Avoid int overflow.
21655 * font.c (font_list_entities): Redo for clarity,
21656 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
21658 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
21659 (font_score): Avoid potential overflow in diff calculation.
21661 * fns.c (substring_both): Remove var that is set but not used.
21662 (sxhash): Redo loop for clarity and to avoid wraparound warning.
21664 * eval.c (funcall_lambda): Rename local to avoid shadowing.
21666 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
21667 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
21668 can always succeed if overflow has undefined behavior.
21670 * search.c (boyer_moore, wordify): Remove vars set but not used.
21671 (wordify): Omit three unnecessary tests.
21673 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
21674 All callers changed. This avoids the need for an unused var.
21676 * casefiddle.c (casify_region): Remove var that is set but not used.
21678 * dired.c (file_name_completion): Remove var that is set but not used.
21680 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
21682 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
21683 (Finsert_file_contents): Remove unnecessary code checking fd.
21685 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
21686 Check for integer overflow on size calculations.
21688 * buffer.c (Fprevious_overlay_change): Remove var that is set
21691 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
21692 Remove vars that are set but not used.
21693 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
21694 (timer_check_2): Mark vars as initialized.
21696 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
21698 * image.c (lookup_image): Remove var that is set but not used.
21699 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
21701 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
21702 that are set but not used.
21704 * xfns.c (make_invisible_cursor): Don't return garbage
21705 if XCreateBitmapFromData fails (Bug#8410).
21707 * xselect.c (x_get_local_selection, x_handle_property_notify):
21708 Remove vars that are set but not used.
21710 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
21711 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
21713 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
21714 Remove var that is set but not used.
21715 (scroll_bar_windows_size): Now size_t, not int.
21716 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
21717 Check for overflow.
21719 * xfaces.c (realize_named_face): Remove vars that are set but not used.
21720 (map_tty_color) [!defined MSDOS]: Likewise.
21722 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
21724 * coding.c: Remove vars that are set but not used.
21725 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
21726 All callers changed.
21727 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
21728 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
21729 (decode_coding_charset): Remove vars that are set but not used.
21731 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
21732 that is set but not used.
21734 * print.c (print_object): Remove var that is set but not used.
21736 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
21737 The gnulib version avoids calling malloc in the usual case,
21738 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
21739 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
21740 * filelock.c (current_lock_owner): Likewise.

21743 (emacs_no_realloc_allocator): New static constant.
21744 (emacs_readlink): New function.
21745 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on

21772 do not dereference NULL upon failed strdup
21773 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
21774 (ns_get_family): Likewise.
21776 2011-04-02 Juanma Barranquero <lekktu@gmail.com>

21780 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
21782 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
21785 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
21787 Add lexical binding.

21798 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
21800 (syms_of_lread): Declare `lexical-binding'.
21802 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
21804 * keyboard.c (eval_dyn): New fun.
21805 (menu_item_eval_property): Use it.

21813 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
21814 (FletX, Flet): Obey lexical binding.
21815 (Fcommandp): Handle closures.
21816 (Feval): New `lexical' arg.
21817 (eval_sub): New function extracted from Feval. Use it almost
21818 everywhere where Feval was used. Look up vars in lexical env.
21820 (Ffunctionp): Move from subr.el.
21821 (Ffuncall): Handle closures.
21822 (apply_lambda): Remove `eval_flags'.
21823 (funcall_lambda): Handle closures and new byte-code-functions.
21824 (Fspecial_variable_p): New function.
21825 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
21826 but without exporting it to Lisp.
21828 * doc.c (Fdocumentation, store_function_docstring):
21829 * data.c (Finteractive_form): Handle closures.
21831 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
21834 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
21836 (exec_byte_code): New function extracted from Fbyte_code to handle new
21837 calling convention for byte-code-functions. Add new byte-codes.
21839 * buffer.c (defvar_per_buffer): Set new `declared_special' field.

21845 * xdisp.c (redisplay_internal): Fix prototype.
21847 2011-03-31 Eli Zaretskii <eliz@gnu.org>
21849 * xdisp.c (SCROLL_LIMIT): New macro.
21850 (try_scrolling): Use it when setting scroll_limit.
21851 Limit scrolling to 100 screen lines.
21852 (redisplay_window): Even when falling back on "recentering",
21853 position point in the window according to scroll-conservatively,
21854 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
21856 (try_scrolling): When point is above the window, allow searching
21857 as far as scroll_max, or one screenful, to compute vertical
21858 distance from PT to the scroll margin position. This prevents
21859 try_scrolling from unnecessarily failing when
21860 scroll-conservatively is set to a value slightly larger than the
21861 window height. Clean up the case of PT below the margin at bottom
21862 of window: scroll_max can no longer be INT_MAX. When aggressive
21863 scrolling is in use, don't let point enter the opposite scroll
21864 margin as result of the scroll.
21865 (syms_of_xdisp) <scroll-conservatively>: Document the
21866 threshold of 100 lines for never-recentering scrolling.
21868 2011-03-31 Juanma Barranquero <lekktu@gmail.com>

21876 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
21878 * indent.c (Fvertical_motion):
21879 * window.c (window_scroll_pixel_based, Frecenter):
21880 Don't pass `need_y_p' to `move_it_by_lines'.
21882 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
21884 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
21885 steal a few bits to be more compact.
21886 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
21887 Remove unneeded casts.
21889 * bytecode.c (Fbyte_code): CAR and CDR can GC.
21891 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
21893 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
21894 binding" message (bug#7967).
21896 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
21898 Fix more problems found by GCC 4.6.0's static checks.
21900 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
21901 Remove unused local var.
21903 * editfns.c (Fmessage_box): Remove unused local var.
21905 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
21906 (note_mode_line_or_margin_highlight, note_mouse_highlight):
21907 Omit unused local vars.
21908 * window.c (shrink_windows): Omit unused local var.
21909 * menu.c (digest_single_submenu): Omit unused local var.
21910 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
21911 Omit unused local var.
21913 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
21914 Don't assume string length fits in int.
21915 (keyremap_step, read_key_sequence): Use size_t for sizes.
21916 (read_key_sequence): Don't check last_real_key_start redundantly.
21918 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
21919 instead of alloca (Bug#8344).
21921 * eval.c (Fbacktrace): Don't assume nargs fits in int.
21922 (Fbacktrace_frame): Don't assume nframes fits in int.
21924 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.

21931 * cm.c (calccost): Turn while-do into do-while, for clarity.
21933 * keyboard.c (syms_of_keyboard): Use the same style as later
21934 in this function when indexing through an array. This also
21935 works around GCC bug 48267.
21937 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
21939 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
21941 * chartab.c (sub_char_table_ref_and_range): Redo for slight
21942 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
21944 * keyboard.c, keyboard.h (num_input_events): Now size_t.
21945 This avoids undefined behavior on integer overflow, and is a bit
21946 more convenient anyway since it is compared to a size_t variable.
21948 Variadic C functions now count arguments with size_t, not int.
21949 This avoids an unnecessary limitation on 64-bit machines, which
21950 caused (substring ...) to crash on large vectors (Bug#8344).

21960 * fns.c (concat): Likewise.
21961 * frame.c (x_set_frame_parameters): Likewise.
21962 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
21963 0 if not found, not -1. All callers changed.
21965 * alloc.c (garbage_collect): Don't assume stack size fits in int.
21966 (stack_copy_size): Now size_t, not int.
21967 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
21969 2011-03-28 Juanma Barranquero <lekktu@gmail.com>

21988 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
21989 don't set the hook to nil, but remove the offending function instead.
21990 (Qcommand_hook_internal): Remove, unused.
21991 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
21992 Vcommand_hook_internal.

21995 (funcall_nil, funcall_not): New functions.
21996 (run_hook_with_args): Call each function through a `funcall' argument.

22010 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.

22175 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
22176 unconditionally since it does the check itself.
22178 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
22180 Fix more problems found by GCC 4.5.2's static checks.
22182 * coding.c (encode_coding_raw_text): Avoid unnecessary test
22183 the first time through the loop, since we know p0 < p1 then.
22184 This also avoids a gcc -Wstrict-overflow warning.
22186 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
22187 leading to a memory leak, possible in functions like
22188 load_charset_map_from_file that can allocate an unbounded number
22189 of objects (Bug#8318).
22191 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
22192 that could (at least in theory) be that large.
22194 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
22195 This is less likely to overflow, and avoids undefined behavior if
22196 overflow does occur. All callers changed. Use strtoul to scan
22197 for the unsigned long integer.
22198 (pint2hrstr): Simplify and tune code slightly.
22199 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
22201 * scroll.c (do_scrolling): Work around GCC bug 48228.
22202 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
22204 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
22205 This also avoids a warning with gcc -Wstrict-overflow.
22206 (validate_x_resource_name): Simplify count usage.
22207 This also avoids a warning with gcc -Wstrict-overflow.
22209 * fileio.c (Fcopy_file): Report error if fchown or fchmod
22212 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
22214 * process.c (Fmake_network_process): Use socklen_t, not int,
22215 where POSIX says socklen_t is required in portable programs.
22216 This fixes a porting bug on hosts like 64-bit HP-UX, where
22217 socklen_t is wider than int (Bug#8277).
22218 (Fmake_network_process, server_accept_connection):
22219 (wait_reading_process_output, read_process_output):
22222 * process.c: Rename or move locals to avoid shadowing.

22232 Make tparam.h and terminfo.c consistent.
22233 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
22234 Include tparam.h instead, since it declares them.
22235 * cm.h (PC): Remove extern decl; tparam.h now does this.
22236 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
22237 * terminfo.c: Include tparam.h, to check interfaces.
22238 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
22239 (tparam): Adjust signature to match interface in tparam.h;
22240 this removes some undefined behavior. Check that outstring and len
22241 are zero, which they always are with Emacs.
22242 * tparam.h (PC, BC, UP): New extern decls.
22244 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
22245 (xftfont_open): Rename locals to avoid shadowing.
22247 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.

22257 * xml.c (make_dom): Now static.
22259 * composite.c (composition_compute_stop_pos): Rename local to
22261 (composition_reseat_it): Remove unused locals.
22262 (find_automatic_composition, composition_adjust_point): Likewise.
22263 (composition_update_it): Mark var as initialized.
22264 (find_automatic_composition): Mark vars as initialized,
22265 with a FIXME (Bug#8290).

22268 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
22269 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
22270 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
22271 (BUF_DEC_POS): Be more systematic about renaming local temporaries
22272 to avoid shadowing.
22274 * textprop.c (property_change_between_p): Remove; unused.
22276 * intervals.c (interval_start_pos): Now static.
22278 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

22281 Rename locals to avoid shadowing.
22283 * sound.c (wav_play, au_play, Fplay_sound_internal):
22284 Fix pointer signedness.
22285 (alsa_choose_format): Remove unused local var.
22286 (wav_play): Initialize a variable to 0, to prevent undefined
22287 behavior (Bug#8278).
22289 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
22291 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
22293 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
22294 clobbering (Bug#8298).
22295 * sysdep.c (sys_subshell): Likewise.
22296 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
22298 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
22299 This should get cleaned up, so that child_setup has the
22300 same signature on all platforms.
22302 * callproc.c (call_process_cleanup): Now static.
22303 (relocate_fd): Rename locals to avoid shadowing.
22305 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
22307 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
22308 not to be necessary, and produces flickering.
22310 2011-03-20 Glenn Morris <rgm@gnu.org>
22312 * config.in: Remove file.
22314 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
22316 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
22317 are now in src/globals.h.
22318 (syms_of_minibuf): Remove spurious & from previous change.
22320 2011-03-20 Leo Liu <sdl.web@gmail.com>
22322 * minibuf.c (completing-read-function): New variable.
22323 (completing-read-default): Rename from completing-read.
22324 (completing-read): Call completing-read-function.
22326 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
22328 * xfaces.c (Fx_load_color_file):
22329 Read color file from absolute filename (bug#8250).
22331 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
22333 * makefile.w32-in: Update dependencies.
22335 2011-03-17 Eli Zaretskii <eliz@gnu.org>
22337 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.

22344 (sigchld_handler): Now static.
22346 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
22347 That way, the code declares only the vars that it needs.
22348 * s/aix4-2.h (PTY_ITERATION): Declare iteration vars.
22349 * s/cygwin.h (PTY_ITERATION): Likewise.
22350 * s/darwin.h (PTY_ITERATION): Likewise.

22357 (CONSTANTLIM): Remove; unused.
22358 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
22359 Define only if needed.
22361 * unexelf.c (unexec): Name an expression,
22362 to avoid gcc -Wbad-function-cast warning.
22363 Use a different way to cause a compilation error if anyone uses
22364 n rather than nn, a way that does not involve shadowing.
22365 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
22367 * deps.mk (unexalpha.o): Remove; unused.
22369 New file unexec.h, the (simple) interface for unexec (Bug#8267).
22370 * unexec.h: New file.
22371 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
22372 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
22373 Depend on unexec.h.
22374 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
22375 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
22376 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.
22377 Change as necessary to match prototype in unexec.h.
22379 * syntax.c (Fforward_comment, scan_lists): Rename locals to avoid
22381 (back_comment, skip_chars): Mark vars as initialized.

22396 (font_sort_entities): Mark var as initialized.
22398 * character.h (FETCH_CHAR_ADVANCE): Rename locals to avoid shadowing.
22400 * font.c (font_unparse_xlfd): Don't mix pointers to variables with

22424 * callint.c (quotify_arg, quotify_args): Now static.
22425 (Fcall_interactively): Rename locals to avoid shadowing.
22426 Use const pointer when appropriate.

22432 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
22433 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
22434 some of which prompt warnings from gcc -Wbad-function-cast.
22435 (Fformat_time_string, Fencode_time, Finsert_char):
22436 (Ftranslate_region_internal, Fformat):
22437 Rename or remove local vars to avoid shadowing.
22438 (Ftranslate_region_internal): Mark var as initialized.
22440 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
22443 * lisp.h (eassert): Check that the argument compiles, even if
22444 ENABLE_CHECKING is not defined.
22446 * data.c (Findirect_variable): Name an expression, to avoid
22447 gcc -Wbad-function-cast warning.
22448 (default_value, arithcompare, arith_driver, arith_error): Now static.

22456 Rename locals to avoid shadowing.
22457 (mark_stack): Move local variables into the #ifdef region where
22459 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
22460 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
22462 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
22463 (GC_STRING_CHARS): Remove; not used.
22464 (Fmemory_limit): Cast sbrk's returned value to char *.
22466 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
22467 avoids undefined behavior in theory.
22469 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
22471 Use functions, not macros, for up- and down-casing (Bug#8254).
22472 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
22473 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
22474 to use the following functions instead of these macros.
22475 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
22476 EMACS_INT, since callers assume the returned value fits in int.
22477 (upcase1): Likewise, for UPCASE_TABLE.
22478 (uppercasep, lowercasep, upcase): New static inline functions.
22479 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for
22480 the race-condition problem in the old DOWNCASE.

22486 Remove unused local vars.
22487 (FREE_VAR): Rewrite so as not to use empty "else",
22488 which gcc can warn about.
22489 (regex_compile, re_match_2_internal): Mark locals as initialized.
22490 (RETALLOC_IF): Define only if needed.
22491 (WORDCHAR_P): Likewise. This one is never needed, but is used
22492 only in a comment talking about a compiler bug, so put inside
22493 the #if 0 of that comment.
22494 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
22495 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
22498 * search.c (boyer_moore): Rename locals to avoid shadowing.
22499 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):

22510 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
22512 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
22513 Rename locals to avoid shadowing.
22514 (Fvertical_motion): Mark locals as initialized.
22516 * casefiddle.c (casify_object, casify_region): Now static.
22517 (casify_region): Mark local as initialized.
22519 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
22521 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
22522 New macros, so that the caller can use some names other than
22523 gcpro1, gcpro2, etc.
22524 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
22526 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
22527 argument, for consistency with GCPRO2_VAR, etc: it is now the
22528 prefix of the variable, not the variable itself. All uses
22530 * dired.c (directory_files_internal, file_name_completion):
22531 Rename locals to avoid shadowing.
22533 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
22534 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
22535 dired.c's scmp function, had undefined behavior.
22536 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
22537 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
22538 * buffer.h: ... to here, because these macros use current_buffer,
22539 and the new implementation with inline functions needs to have
22540 current_buffer in scope now, rather than later when the macros
22542 (downcase, upcase1): New static inline functions.
22543 (DOWNCASE, UPCASE1): Reimplement using these functions.
22544 This avoids undefined behavior in expressions like
22545 DOWNCASE (x) == DOWNCASE (y), which previously suffered
22546 from race conditions in accessing the global variables
22547 case_temp1 and case_temp2.
22548 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
22549 * lisp.h (case_temp1, case_temp2): Remove their decls.
22550 * character.h (ASCII_CHAR_P): Move from here ...
22551 * lisp.h: ... to here, so that the inline functions mentioned
22552 above can use them.
22554 * dired.c (directory_files_internal_unwind): Now static.
22556 * fileio.c (file_name_as_directory, directory_file_name):
22557 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
22559 (file_name_as_directory): Use const pointers when appropriate.
22560 (Fexpand_file_name): Likewise. In particular, newdir might
22561 point at constant storage, so make it a const pointer.
22562 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
22563 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
22565 (Fset_file_times, Finsert_file_contents, auto_save_error):
22566 Rename locals to avoid shadowing.
22568 * minibuf.c (choose_minibuf_frame_1): Now static.
22569 (Ftry_completion, Fall_completions): Rename or remove locals
22570 to avoid shadowing.
22572 * marker.c (bytepos_to_charpos): Remove; unused.
22574 * lisp.h (verify_bytepos, count_markers): New decls,
22575 so that gcc does not warn that these functions aren't declared.
22577 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
22578 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
22579 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
22580 (copy_text): Remove unused local var.
22582 * filelock.c (within_one_second): Now static.
22583 (lock_file_1): Rename local to avoid shadowing.
22585 * buffer.c (fix_overlays_before): Mark locals as initialized.
22586 (fix_start_end_in_overlays): Likewise. This function should be
22587 simplified by using pointers-to-pointers, but that's a different
22589 (switch_to_buffer_1): Now static.
22590 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
22591 (report_overlay_modification): Rename locals to avoid shadowing.
22593 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
22594 Fix pointer signedness issue.
22595 (sys_subshell): Mark local as volatile if checking for lint,
22596 to suppress a gcc -Wclobbered warning that does not seem to be right.
22597 (MAXPATHLEN): Define only if needed.
22599 * process.c (serial_open, serial_configure): Move decls from here ...
22600 * systty.h: ... to here, so that they can be checked.
22602 * fns.c (get_random, seed_random): Move extern decls from here ...
22603 * lisp.h: ... to here, so that they can be checked.
22605 * sysdep.c (reset_io): Now static.
22606 (wait_for_termination_signal): Remove; unused.
22608 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):

22611 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
22612 (DENSE_TABLE_SIZE): Remove; unused.
22613 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
22614 (describe_map_tree):
22615 Rename locals to avoid shadowing.
22617 * keyboard.c: Declare functions static if they are not used elsewhere.
22618 (echo_char, echo_dash, cmd_error, top_level_2):
22619 (poll_for_input, handle_async_input): Now static.
22620 (read_char, kbd_buffer_get_event, make_lispy_position):
22621 (make_lispy_event, make_lispy_movement, apply_modifiers):

22623 (parse_tool_bar_item, read_key_sequence, Fread_key_sequence):
