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

65 source bytes directly.
66 (produce_chars): Call insert_from_gap with the new arg 0.
67 (encode_coding): Likewise.
68 (decode_coding_gap): Control ASCII optimization by the variable

89 2013-03-14 Eli Zaretskii <eliz@gnu.org>
91 * w32term.c (w32_read_socket) <WM_WINDOWPOSCHANGED>: Remove old
92 and incorrect code. Treat WM_WINDOWPOSCHANGED like WM_ACTIVATE
94 (w32fullscreen_hook): If the frame is visible, reset
95 f->want_fullscreen flag after changing the frame size. If the
96 frame is not visible, set f->want_fullscreen to FULLSCREEN_WAIT.
99 2013-03-13 Daniel Colascione <dancol@dancol.org>
101 * emacs.c (main): Call syms_of_cygw32 on CYGWIN non-NTGUI builds
102 too so that these builds can use Cygwin's file conversion
103 functions. (We've been building and linking cygw32.o all along
104 and just not using it.)
106 2013-03-13 Paul Eggert <eggert@cs.ucla.edu>
108 File synchronization fixes (Bug#13944).
109 * Makefile.in (LIB_FDATASYNC): New macro.
111 * conf_post.h (BSD_SYSTEM, BSD_SYSTEM_AHB): Remove; no longer needed.
112 * fileio.c (Fwrite_region, write_region_inhibit_fsync):

119 * w32term.c (w32_read_socket): If the Emacs frame is being
120 activated, call w32fullscreen_hook, to make sure the new frame
121 dimensions are in effect. (Bug#13937)
123 2013-03-13 Dmitry Antipov <dmantipov@yandex.ru>
125 * xdisp.c (init_iterator): Simplify because both character and byte
126 positions are either specified or -1. Add eassert. Adjust comment.
127 * window.c (Fscroll_other_window): Use SET_PT_BOTH because both
128 character and byte positions can be obtained from marker.
130 2013-03-13 Paul Eggert <eggert@cs.ucla.edu>

145 a function pointer type; the C Standard requires this.
147 * sysdep.c: Remove a use of BSD_SYSTEM, which I'm trying to phase out.
148 Include <sys/param.h> unconditionally, as that works elsewhere and
149 is simpler here. Include <sys/sysctl.h> if DARWIN_OS ||
150 __FreeBSD__, not if BSD_SYSTEM, since it's needed only for Darwin
153 2013-03-11 Paul Eggert <eggert@cs.ucla.edu>

182 common file dialog code.
184 * w32fns.c (Ffile_system_info): Remove from cygw32 builds, which
185 can just use du like other systems.
187 * coding.c (from_unicode_buffer): Declare.
188 * coding.c (from_unicode_buffer): Implement.
190 2013-03-10 Stefan Monnier <monnier@iro.umontreal.ca>

231 (adjust_after_insert): Call adjust_after_replace with the new arg
234 2013-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
236 * keyboard.h (EVENT_START, EVENT_END, POSN_WINDOW, POSN_POSN)
237 (POSN_WINDOW_POSN, POSN_TIMESTAMP): Be careful since events may come
238 from Elisp via unread-command-events.
240 * keyboard.c (access_keymap_keyremap): Accept nil return value from
241 functions to mean "no change".
243 2013-03-08 Paul Eggert <eggert@cs.ucla.edu>
245 region-cache.c, scroll.c, search.c: Use bool for booleans.

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

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

265 Adjust call to find_newline.
266 * indent.c (vmotion): Adjust calls to find_newline_no_quit.

270 (get_visually_first_element, move_it_vertically_backward): Likewise.
271 Obtain byte position from the display iterator, where appropriate.
273 2013-03-08 Paul Eggert <eggert@cs.ucla.edu>

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

298 when you need just to move to the previous buffer position.
299 * xdisp.c (Fcurrent_bidi_paragraph_direction): Use DEC_BOTH.
301 2013-03-07 Eli Zaretskii <eliz@gnu.org>
303 * .gdbinit (prowlims): Display the enabled_p flag of the row.

374 2013-03-06 Paul Eggert <eggert@cs.ucla.edu>
376 Fix a build failure on OpenBSD 4.x and MirBSD (Bug#13881).
377 * sysdep.c (list_system_processes)
378 [BSD_SYSTEM && !DARWIN_OS && !__FreeBSD__]:
379 Make it a stub in this case; otherwise the build might fail,
380 and this code hasn't been tested on such hosts anyway.
381 Problem reported by Nelson H. F. Beebe in
382 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00021.html>
383 and analyzed by Jérémie Courrèges-Anglas in
384 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00062.html>.
386 2013-03-06 Dmitry Antipov <dmantipov@yandex.ru>
388 * lisp.h (find_next_newline_no_quit): Rename to find_next_newline.
389 * xdisp.c (back_to_previous_line_start, forward_to_next_line_start)
390 (get_visually_first_element, move_it_vertically_backward): Ajust users.
391 * bidi.c (bidi_find_paragraph_start): Likewise.
392 * indent.c (vmotion): Likewise.
394 2013-03-05 Paul Eggert <eggert@cs.ucla.edu>
396 FILE's lock is now always .#FILE and may be a regular file (Bug#13807).
397 * filelock.c: Include <c-ctype.h>.
398 (MAX_LFINFO): New top-level constant.
399 (lock_info_type): Remove members pid, boot_time. Add members at,
400 dot, colon. Change user member to be the entire buffer, not a
401 pointer. This allows us to handle the case where a foreign
402 pid or boot time exceeds the local range. All uses changed.
403 (LINKS_MIGHT_NOT_WORK): New constant.
404 (FREE_LOCK_INFO): Remove, as the pieces no longer need freeing.
405 (defined_WINDOWSNT): Remove.
406 (MAKE_LOCK_NAME, file_in_lock_file_name):
407 Always use .#FILE (not .#-FILE) for the file lock,
408 even if it is a regular file.
409 (rename_lock_file): New function.
410 (create_lock_file): Use it.
411 (create_lock_file, read_lock_data):
412 Prefer a symbolic link for the lock file, falling back on a
413 regular file if symlinks don't work. Do not try to create
414 symlinks on MS-Windows, due to security hassles. Stick with
415 POSIXish functions (open, read, write, close, fchmod, readlink, symlink,
416 link, rename, unlink, mkstemp) when creating locks, as a GNUish
417 host may be using a Windowsish file system, and cannot use
418 MS-Windows-only system calls. Fall back on mktemp if mkstemp
419 doesn't work. Don't fail merely because of a symlink-contents
420 length limit in the current file system; fall back on regular
421 files. Increase the symlink contents length limit to 8 KiB, this
422 should be big enough for any real use and doesn't crunch the
424 (create_lock_file, lock_file_1, read_lock_data):
425 Simplify allocation of lock file buffers now that they fit in 8 KiB.
426 (lock_file_1): Return error number, not bool. All callers changed.
427 (ELOOP): New macro, if not already defined.
428 (read_lock_data): Return size of lock file contents, not Lisp object.
429 All callers changed. Handle a race condition if some other process
430 replaces a regular-file lock with a symlink lock or vice versa,
431 while we're trying to read the lock.
432 (current_lock_owner): Parse contents more carefully, to help avoid
433 confusing a regular-file lock with some other application's use
434 of the file. Check for lock file contents being too long, or
435 not parsing correctly.
436 (current_lock_owner, lock_file):
437 Allow foreign pid and boot times that exceed the local range.
438 (current_lock_owner, lock_if_free, lock_file):
439 Simplify allocation of lock file contents.
440 * w32.c (sys_rename_replace): New function, containing most of
441 the contents of the old sys_rename.
442 (sys_rename): Use it.
443 (fchmod): New dummy function.
444 * w32.h (sys_rename_replace, fchmod): New decls.
446 2013-03-05 Eli Zaretskii <eliz@gnu.org>
448 * bidi.c (bidi_resolve_explicit_1): Don't call CHAR_TO_BYTE or
449 bidi_count_bytes, as the callers now arrange for bidi_it->charpos
450 to be in sync with bidi_it->bytepos. Suggested by Dmitry Antipov
451 <dmantipov@yandex.ru>.
453 2013-03-05 Dmitry Antipov <dmantipov@yandex.ru>
455 * composite.c (get_composition_id, fill_gstring_header):
456 Use make_uninit_vector where appropriate.
457 * font.c (Ffont_get_glyphs, build_style_table): Likewise.
458 * xselect.c (clean_local_selection_data): Likewise.
460 2013-03-04 Paul Eggert <eggert@cs.ucla.edu>
462 Fix misuse of ImageMagick that caused core dump (Bug#13846).
463 * image.c (imagemagick_load_image): Calculate height and width
464 after flattening the image, not before.
466 2013-03-04 Dmitry Antipov <dmantipov@yandex.ru>
468 * font.c (Ffont_get_glyphs): Use convenient LGLYPH_NEW.
469 * ftfont.c (ftfont_shape_by_flt): Likewise.
470 * w32uniscribe.c (uniscribe_shape): Likewise.
472 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
474 The lock for FILE is now .#FILE or .#-FILE (Bug#13807).
475 The old approach, which fell back on DIR/.#FILE.0 through
476 DIR/.#FILE.9, had race conditions that could not be easily fixed.
477 If DIR/.#FILE is a non-symlink file, Emacs now does not create a
478 lock file for DIR/FILE; that is, DIR/FILE is no longer partly
479 protected by a lock if DIR/.#FILE is a non-symlink file ("partly"
480 because the locking mechanism was never reliable in that case).
481 This patch fixes this and other bugs discovered by a code
482 inspection that was prompted by
483 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00531.html>.
484 Also, this patch switches to .#-FILE (not .#FILE) on MS-Windows,
485 to avoid interoperability problems between the MS-Windows and
486 non-MS-Windows implementations. MS-Windows and non-MS-Windows
487 instances of Emacs now ignore each others' locks.
488 * filelock.c (defined_WINDOWSNT): New constant.
489 (MAKE_LOCK_NAME, fill_in_lock_file_name):
490 Don't create DIR/.#FILE.0 through DIR/.#FILE.9. Instead, create
491 DIR/.#FILE symlinks on non-MS-Windows hosts, and DIR/.#-FILE
492 regular files on MS-Windows hosts.
493 (MAKE_LOCK_NAME, unlock_file, Ffile_locked_p):
494 Use SAFE_ALLOCA to avoid problems with long file names.
495 (MAX_LFINFO): Now a local constant, not a global macro.
496 (IS_LOCK_FILE): Remove.
497 (lock_file_1): Don't inspect errno if symlink call succeeds;
499 (lock_file): Document that this function can return if lock
501 (lock_file): Don't access freed storage.
503 2013-03-02 Andreas Schwab <schwab@linux-m68k.org>
505 * lisp.h (XPNTR) [!USE_LSB_TAG]: Remove extra paren. (Bug#13734)
507 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
509 * textprop.c: Use bool for booleans.
510 (validate_interval_range, Fadd_text_properties)
511 (Fremove_text_properties): Prefer bool to int when either works.
513 2013-03-02 Eli Zaretskii <eliz@gnu.org>
515 * textprop.c (Fadd_text_properties, Fremove_text_properties):
516 If the interval tree changes as a side effect of calling
517 modify_region, re-do processing starting from the call to
518 validate_interval_range. (Bug#13743)
520 2013-02-28 Eli Zaretskii <eliz@gnu.org>
522 * w32.c (sys_open): Don't reset the flags for FD in fd_info[].
525 2013-02-27 Eli Zaretskii <eliz@gnu.org>
527 * filelock.c (create_lock_file) [WINDOWSNT]: Use _sopen with
528 _SH_DENYRW flag, instead of emacs_open, to deny any other process
529 access to the lock file until it is written and closed.
532 2013-02-27 Paul Eggert <eggert@cs.ucla.edu>
534 * callint.c (Qcall_interactively):
535 * macros.c (Qexecute_kbd_macro):
538 2013-02-26 Bastien Guerry <bzg@gnu.org>
540 * window.c (Frecenter): Tiny docstring enhancement.
542 2013-02-26 Paul Eggert <eggert@cs.ucla.edu>
544 Minor textprop integer cleanup.
545 * intervals.h, textprop.c (add_text_properties_from_list):
546 Return void, not int, since nobody uses the return value.
547 * textprop.c (validate_plist, add_properties, remove_properties)
548 (Fadd_text_properties):
549 Don't assume list length fits in int.
550 (interval_has_all_properties, interval_has_some_properties)
551 (interval_has_some_properties_list, add_properties, remove_properties)
552 (Fadd_text_properties, Fremove_text_properties)
553 (Fremove_list_of_text_properties, text_property_stickiness):
554 Use bool for booleans.
555 (Fadd_text_properties, Fremove_text_properties):
556 (Fremove_list_of_text_properties):
557 Reindent do-while as per GNU style.
559 2013-02-25 Eli Zaretskii <eliz@gnu.org>
561 Implement CLASH_DETECTION for MS-Windows.
563 * filelock.c [WINDOWSNT]: Include w32.h.
564 (MAKE_LOCK_NAME): Don't use 'lock', it clashes with MS runtime
565 function of that name. Up-case the macro arguments.
566 (IS_LOCK_FILE): New macro.
567 (fill_in_lock_file_name): Use IS_LOCK_FILE instead of S_ISLNK.
568 (create_lock_file): New function, with body extracted from
570 [WINDOWSNT]: Implement lock files by writing a regular file with
571 the lock information as its contents.
572 (read_lock_data): New function, on Posix platforms just calls
574 [WINDOWSNT]: Read the lock info from the file.
575 (current_lock_owner): Call read_lock_data instead of calling
576 emacs_readlinkat directly.
577 (lock_file) [WINDOWSNT]: Run the file name through
580 * w32proc.c (sys_kill): Support the case of SIG = 0, in which case
581 just check if the process by that PID exists.
583 * w32.c (sys_open): Don't reset the _O_CREAT flag if _O_EXCL is
584 also present, as doing so will fail to error out if the file
587 * makefile.w32-in ($(BLD)/filelock.$(O)): Depend on src/w32.h.
589 * textprop.c (Fadd_text_properties, Fremove_text_properties)
590 (Fremove_list_of_text_properties): Skip all of the intervals in
591 the region between START and END that already have resp. don't
592 have the requested properties, not just the first one.
593 Add assertions that the loop afterwards always modifies the
594 properties. (Bug#13743)
596 2013-02-25 Stefan Monnier <monnier@iro.umontreal.ca>
598 * callint.c (Fcall_interactively): Use the right lexical environment
599 for `interactive' specs (bug#13811).
600 * eval.c (Feval): Accept a lexical environment.
602 2013-02-25 Paul Eggert <eggert@cs.ucla.edu>

606 * Makefile.in (LD_FIRSTFLAG, LIB_GCC, CRT_DIR, LIB_STANDARD)
607 (START_FILES): Remove. All uses removed.
608 (otherobj): Remove $(VMLIMIT_OBJ), as it's now first.
609 (ALLOBJS): Move here from autodeps.mk, and with VMLIMITS_OBJ first.
610 (buildobj.h): Use it.
611 ($(ALLOBJS)): Depend on globals.h.
612 (temacs$(EXEEXT)): Use $(ALLOBJS).
613 * autodeps.mk (ALLOBJS): Move to Makefile.in.
614 * deps.mk (vm-limit.o):
615 * makefile.w32-in ($(BLD)/vm-limit.$(O)):
616 Do not depend on mem-limits.h.
617 * emacs.c (__do_global_ctors, __do_global_ctors_aux)
618 (__do_global_dtors, __CTOR_LIST__, __DTOR_LIST__)
619 [__GNUC__ && !ORDINARY_LINK]: Remove.
620 * mem-limits.h, pre-crt0.c: Remove.
621 * unexaix.c, unexcoff.c: Don't include mem-limits.h.

623 (make_hdr): Use DATA_START instead of start_of_data.
624 * vm-limit.c: Move most of mem-limits.h's contents here.
625 (data_start): New decl. It's OK if this is approximate,
626 so simplify-away some unnecessary exactness.
627 (POINTER): Remove; all uses removed.
628 (data_space_start): Now char *, to avoid casts.
629 (exceeds_lisp_ptr): New function, replacing the old
630 EXCEEDS_LISP_PTR macro. All uses changed.
631 (check_memory_limits): Simplify and remove casts.
632 (start_of_data) [!CANNOT_DUMP || !SYSTEM_MALLOC]: Remove.
633 (memory_warnings): Use data_start instead of start_of_data.
635 2013-02-24 Andreas Schwab <schwab@linux-m68k.org>
637 * xdisp.c (set_message): Only check for debug-on-message if STRING
638 is a string. (Bug#13797)
640 2013-02-24 Paul Eggert <eggert@cs.ucla.edu>

645 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00533.html>
646 and diagnosed by Andreas Schwab in
647 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00534.html>.
649 2013-02-22 Paul Eggert <eggert@cs.ucla.edu>
651 Assume C89 or better.
652 * ralloc.c (SIZE, POINTER, NIL):
653 * vm-limit.c (POINTER):
654 Remove, replacing all uses with C89 equivalents. These old
655 symbols were present only for porting to pre-C89 platforms.
657 2013-02-22 Claudio Bley <claudio.bley@gmail.com>
659 * w32.c (emacs_gnutls_pull): Don't call 'select', and don't loop.
660 This avoids warning messages reported as part of Bug#13546.
662 2013-02-21 Ken Brown <kbrown@cornell.edu>
664 * sheap.c (report_sheap_usage): Fix arguments of message1_no_log.
666 2013-02-20 Stefan Monnier <monnier@iro.umontreal.ca>

670 * keyboard.c (Qcommand_execute): New var.
671 (command_loop_1, read_char): Use it.
672 (Fcommand_execute): Remove, replace by an Elisp implementation.
673 (syms_of_keyboard): Adjust accordingly.
675 2013-02-19 Daniel Colascione <dancol@dancol.org>
677 * sheap.c (report_sheap_usage): Use message, not message1, so
678 that we don't try to create a buffer while we're in the middle
679 of dumping Emacs. Explain why.
681 2013-02-20 Dmitry Antipov <dmantipov@yandex.ru>
683 * search.c (find_newline): Return byte position in bytepos.
685 (find_next_newline_no_quit, find_before_next_newline):
686 Add bytepos argument.
687 * lisp.h (find_newline, find_next_newline_no_quit)
688 (find_before_next_newline): Adjust prototypes.
689 * bidi.c (bidi_find_paragraph_start):
690 * editfns.c (Fconstrain_to_field, Fline_end_position):
691 * indent.c (compute_motion, vmotion):
692 * xdisp.c (back_to_previous_line_start, forward_to_next_line_start):
693 (get_visually_first_element, move_it_vertically_backward):
694 Adjust users and avoid calls to CHAR_TO_BYTE where appropriate.
696 2013-02-19 Eli Zaretskii <eliz@gnu.org>
698 * w32proc.c (new_child): Avoid leaking handles if the subprocess
699 resources were not orderly released.
701 2013-02-17 Eli Zaretskii <eliz@gnu.org>
703 * xdisp.c (x_draw_vertical_border): For a window that is neither
704 the leftmost nor the rightmost, redraw both the left and the right
705 vertical borders. (Bug#13723)
707 2013-02-17 Stefan Monnier <monnier@iro.umontreal.ca>
709 * xml.c (init_libxml2_functions):
710 * sound.c (sound_warning):
711 * sheap.c (report_sheap_usage):
712 * process.c (wait_reading_process_output):
713 * msdos.c (XMenuActivate):
714 * macros.c (Fstart_kbd_macro, Fend_kbd_macro):
715 * keyboard.c (top_level_1):
716 * editfns.c (Fmessage, Fmessage_box):
717 * callint.c (Fcall_interactively):
718 * fns.c (Fyes_or_no_p): Prefer `message1' over `message'.
720 2013-02-17 Jan Djärv <jan.h.d@swipnet.se>
722 * xterm.c (syms_of_xterm): Move scroll-bar-adjust-thumb-portion ...
723 * frame.c (syms_of_frame): ... to here.
725 2013-02-16 Eli Zaretskii <eliz@gnu.org>
727 * w32.c (sys_chown): Remove unused function.
729 * w32term.c <input_signal_count>: Declare 'volatile'
730 unconditionally. (Bug#9066)
732 * w32.c (set_errno): Reset h_errno and don't set it to any other
733 value. Set errno instead.
734 (check_errno): Reset h_errno.
735 (sys_socket, socket_to_fd, sys_bind, sys_connect)
736 (sys_gethostname, sys_getservbyname, sys_getpeername)
737 (sys_shutdown, sys_setsockopt, sys_listen, sys_getsockname)
738 (sys_accept, sys_recvfrom, sys_sendto, fcntl, sys_read): Don't set
740 (sys_gethostbyname): Set h_errno only errors detected.
742 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
744 * process.c (h_errno) [!HAVE_H_ERRNO]: Remove unused decl.
746 2013-02-15 Eli Zaretskii <eliz@gnu.org>
748 * keyboard.c (read_char): Fix calculation of auto-save time out
749 when auto-save-timeout is less than 4. (Bug#13720)
751 * w32proc.c (new_child): Free up to 2 slots of dead processes at a
752 time. Improve diagnostics in DebPrint. (Bug#13546)

755 (sys_gethostbyname, sys_getservbyname, sys_getpeername)
756 (sys_shutdown, sys_setsockopt, sys_listen, sys_getsockname)
757 (sys_accept, sys_recvfrom, sys_sendto, fcntl): In case of failure,
758 make sure errno is set to an appropriate value. (Bug#13546)
759 (socket_to_fd): Add assertion against indexing fd_info[] with a
760 value that is out of bounds.
761 (sys_accept): If fd is negative, do not set up the child_process
762 structure for reading.
764 2013-02-15 Dmitry Antipov <dmantipov@yandex.ru>
766 * composite.c (fill_gstring_header): Remove useless prototype.
768 * lisp.h (message_dolog, compile_pattern): Adjust prototype.
769 * print.c (PRINTDECLARE, print_object):
770 * search.c (compile_pattern, fast_looking_at, search_buffer):
771 (simple_search, boyer_moore, Freplace_match):
772 * xdisp.c (c_string_pos, number_of_chars, message_dolog):
773 (get_overlay_arrow_glyph_row, display_mode_element):
774 (decode_mode_spec_coding, message3):
775 * xfaces.c (face_at_string_position): Use bool for booleans.
778 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
780 Fix AIX port (Bug#13650).
781 * lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]:
782 Fix bug introduced in 2012-07-27 change. DATA_SEG_BITS, if set,
783 was #undeffed earlier, so it cannot be used as a macro here.
784 Use the constant and not the macro.
786 2013-02-15 Eli Zaretskii <eliz@gnu.org>
788 * w32proc.c (new_child): If no vacant slots are found in
789 child_procs[], make another pass looking for slots whose process
790 has exited or died. (Bug#13546)
792 * w32.c (sys_pipe): When failing due to file descriptors above
793 MAXDESC, set errno to EMFILE.
794 (_sys_read_ahead): Update cp->status when failing to read serial
795 communications input, so that the status doesn't stay at
796 STATUS_READ_IN_PROGRESS. (Bug#13546)
798 2013-02-14 Jan Djärv <jan.h.d@swipnet.se>
800 * gtkutil.c (tb_size_cb): New function.
801 (xg_create_tool_bar): Connect size-allocate to tb_size_cb (Bug#13512).
803 2013-02-14 Stefan Monnier <monnier@iro.umontreal.ca>
805 * keyboard.c (active_maps): Fcurrent_active_maps expects a position, not
808 2013-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
810 * keyboard.c (syms_of_keyboard): Further tweaks of docstring.
812 2013-02-13 Dmitry Antipov <dmantipov@yandex.ru>
814 * font.c (font_range): Add pos_byte argument. Adjust comment
816 * font.h (font_range): Adjust prototype.
817 * composite.c (autocmp_chars): Pass byte position to font_range.
818 Break long line. Remove useless prototype and format comment.
820 2013-02-13 Glenn Morris <rgm@gnu.org>
822 * keyboard.c (input-decode-map, key-translation-map): Doc fixes.
824 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
826 Improve AIX port some more (Bug#13650).
827 With this, it should be as good as it was in 23.3, though it's
828 still pretty bad: the dumped emacs does not run. See Mark Fleishman in
829 http://lists.gnu.org/archive/html/help-gnu-emacs/2011-04/msg00287.html
830 * unexaix.c (start_of_text): Remove.
831 (_data, _text): Declare as char[], not int, as AIX manual suggests.
832 (bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
833 (orig_load_scnptr, orig_data_scnptr):
834 Now off_t, not long, since they are file offsets.
835 (make_hdr): Use _data, not start_of_data ().
836 This is the key part of the fix.
837 (make_hdr, unrelocate_symbols): Use off_t for file offsets.
838 (unrelocate_symbols): Cast pointers to intptr_t, not to ulong.
840 * pre-crt0.c (data_start): Initialize to 1.
841 This ports to compilers that optimize the external declaration
842 'int x = 0;' as if it were 'int x;' to shrink the executable.
844 Improve AIX port (Bug#13650).
845 This doesn't fix the bug, but it makes progress: Emacs builds now.
846 * unexaix.c: Include inttypes.h, stdarg.h.
847 (report_error, report_error_1): Mark as _Noreturn.
848 (report_error): Don't report the wrong errno.
849 (report_error_1): Now varargs. All callers changed.
850 (make_hdr): Use uintptr_t, not unsigned, when converting pointers
851 to unsigned. Don't use ADDR_CORRECT, as it no longer exists.
852 (write_ptr): Use %p to print address rather than %lx and a cast
853 to unsigned long. Grow buffer a bit, to be safer.
855 2013-02-13 Eli Zaretskii <eliz@gnu.org>
857 * bidi.c (bidi_resolve_neutral): After finding the next
858 non-neutral character, accept NEUTRAL_ON type as well, because
859 directional control characters, such as LRE and RLE, have their
860 type converted to that by bidi_resolve_weak. This avoids aborts
861 when LRE/RLE follows a run of neutrals.
862 (bidi_move_to_visually_next): Assert that return value of
863 bidi_peek_at_next_level is non-negative. Negative values will
866 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
868 Minor getenv-related fixes.
869 * callproc.c (Fcall_process_region) [!DOS_NT]:
870 Avoid unnecessary duplicate call to getenv.
871 * callproc.c (init_callproc):
872 * dispnew.c (init_display):
873 * sysdep.c (sys_subshell):
874 Omit unnecessary cast of getenv or egetenv.
876 2013-02-13 Juanma Barranquero <lekktu@gmail.com>
878 * makefile.w32-in ($(BLD)/filelock.$(O), $(BLD)/sysdep.$(O)):
881 2013-02-12 Eli Zaretskii <eliz@gnu.org>
883 * xdisp.c (redisplay_internal): Don't set w->region_showing to the
885 (display_line): Set w->region_showing to the value of
886 it->region_beg_charpos, not to -1. This fixes redisplay
887 optimization when cursor is moved up after M->. (Bug#13623)
889 (try_scrolling): Scroll text up more if point is too close to ZV
890 and inside the scroll margin. This makes sure point is moved
891 outside the scroll margin in these cases.
893 * window.h (struct window): region_showing can no longer be
896 2013-02-11 Paul Eggert <eggert@cs.ucla.edu>
898 Tune by using memchr and memrchr.
899 * doc.c (Fsnarf_documentation):
900 * fileio.c (Fsubstitute_in_file_name):
901 * search.c (find_newline, scan_newline):
902 * xdisp.c (pos_visible_p, display_count_lines):
903 Use memchr and memrchr rather than scanning byte-by-byte.
904 * search.c (find_newline): Rename from scan_buffer.
905 Omit first arg TARGET, as it's always '\n'. All callers changed.
907 Clean up read_key_sequence a tiny bit more.
908 * keyboard.c (read_char_x_menu_prompt) [HAVE_MENUS]:
909 (read_key_sequence): Remove unused locals.
911 2013-02-11 Stefan Monnier <monnier@iro.umontreal.ca>
913 Clean up read_key_sequence a bit; reread active keymaps after first event.
914 * keyboard.c (read_char, read_char_x_menu_prompt)
915 (read_char_minibuf_menu_prompt):
916 Replace nmaps+maps with a single `map' arg.
917 (follow_key): Operate on a single map.
918 (active_maps): New function.
919 (test_undefined): Also return true for nil bindings.
920 (read_key_sequence): Use active_maps to replace the arrays of keymaps with
921 a single (composed) keymap. Remember `first_event' to choose the right
922 set of active keymaps. Recompute the set of keymaps after receiving
923 the first event. Remove GOBBLE_FIRST_EVENT.
924 (syms_of_keyboard): Remove inhibit_local_menu_bar_menus.
925 * keyboard.h (read_char): Update declaration.
926 * lread.c (read_filtered_event): Adjust call to read_char.
928 2013-02-11 Eli Zaretskii <eliz@gnu.org>
930 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
931 Don't use the limitation on backwards movement when lines are truncated
932 in the window. (Bug#13675)
934 2013-02-11 Dmitry Antipov <dmantipov@yandex.ru>
936 * marker.c (set_marker_internal): If desired position is passed
937 as a marker, avoid call to buf_charpos_to_bytepos.
938 * window.c (Fset_window_point): Omit redundant type checking.
939 (Fset_window_start): Likewise. Format comment.
940 (window_scroll_pixel_based): Use set_marker_restricted_both
941 with character and byte positions obtained from an iterator.
942 (Fset_window_configuration): Use set_marker_restricted_both.
943 * xdisp.c (message_dolog): Likewise.
945 2013-02-10 Eli Zaretskii <eliz@gnu.org>
947 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
948 When text lines are longer than window's screen lines, don't move back
949 too far. This speeds up some redisplay operations. (Bug#13675)
951 2013-02-10 Dmitry Antipov <dmantipov@yandex.ru>
953 * syntax.c (scan_sexps_forward): Fix byte position calculation
954 Bug#13664 (a.k.a Bug#13667) introduced with 2013-02-08 change.
956 2013-02-10 Paul Eggert <eggert@cs.ucla.edu>
958 * fileio.c (Fexpand_file_name): Omit confusing pointer comparison
961 2013-02-09 Paul Eggert <eggert@cs.ucla.edu>
963 Minor hashing refactoring.
964 * fns.c (SXHASH_REDUCE): Move to lisp.h.
965 (sxhash_float): Return EMACS_UINT, for consistency with the other
967 * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
968 non-static inline function and therefore can't use static vars.
969 (SXHASH_REDUCE): Move here from fns.c, and make it inline.
970 * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
971 with the other hash functions.
973 2013-02-09 Eli Zaretskii <eliz@gnu.org>
975 * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
976 XXXXXX part of the temporary file pattern is not downcased even
977 when w32-downcase-file-names is non-nil. (Bug#13661)
979 * xdisp.c (decode_mode_spec): Remove handling of %t.
981 * msdos.c (careadlinkatcwd): Remove.
983 2013-02-08 Stefan Monnier <monnier@iro.umontreal.ca>
985 * lread.c (skip_dyn_bytes): New function (bug#12598).
986 (read1): Use it. Use getc instead of READCHAR to read bytes.
987 (load_each_byte): Remove. Update users.
989 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
991 * search.c (scan_buffer): Calculate end byte position just once.

995 (scan_sexps_forward): Record from_byte and avoid redundant
996 character to byte position calculation ...
997 (Fparse_partial_sexp): ... here. Break too long line.
999 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
1001 * lisp.h (make_uninit_vector): New function.
1002 * alloc.c (Fvector, Fmake_byte_code):

1014 * window.c (Fcurrent_window_configuration):
1015 * xfaces.c (Fx_family_fonts):
1016 * xselect.c (selection_data_to_lisp_data): Use it.
1018 2013-02-07 Dmitry Antipov <dmantipov@yandex.ru>
1020 * coding.c (Fdefine_coding_system_internal): Use AREF where
1021 argument is known to be a vector.
1022 * fns.c (Flocale_info): Likewise for ASET.
1023 * xselect.c (selection_data_to_lisp_data): Likewise for ASET.
1024 * w32fns.c (w32_parse_hot_key): Likewise for ASIZE and AREF.
1026 2013-02-05 Jan Djärv <jan.h.d@swipnet.se>
1028 * nsmenu.m (update_frame_tool_bar): Check for negative tool bar
1031 * nsterm.h (HAVE_NATIVE_FS): Define if OSX => 10.7.
1032 (EmacsView): Add fs_is_native, fsIsNative, isFullscreen and

1035 * nsterm.m (NEW_STYLE_FS): Remove.
1036 (ns_last_use_native_fullscreen): New variable.
1037 (x_make_frame_visible): Replace NEW_STYLE_FS with isFullscreen.
1038 (x_set_window_size): Do not take title bar and tool bar into account
1039 if isFullscreen returns YES.
1040 (ns_fullscreen_hook): Replace NEW_STYLE_FS with isFullscreen.
1041 (check_native_fs): New function.
1042 (ns_select, ns_read_socket): Call check_native_fs if HAVE_NATIVE_FS.
1043 (ns_term_init): Remove NEW_STYLE_FS.
1044 (updateFrameSize:, windowWillResize:toSize:): Only adjust for title bar
1045 and tool bar if isFullscreen returns NO.
1046 (windowDidResize:): Replace NEW_STYLE_FS with fsIsNative.
1047 (initFrameFromEmacs:): Initialize fs_is_native. Replace NEW_STYLE_FS
1048 with HAVE_NATIVE_FS.
1049 (window:willUseFullScreenPresentationOptions:): New method.
1050 (windowDidEnterFullScreen:): Replace NEW_STYLE_FS with fsIsNative.
1051 Hide toolbar if not enabled (Bug#13444).

1058 FRAME_TOOLBAR_HEIGHT (f). Call updateFrameSize when going non-fs.
1059 (syms_of_nsterm): Add ns-use-native-fullscreen.
1061 2013-02-04 Paul Eggert <eggert@cs.ucla.edu>
1063 * fileio.c (Qchoose_write_coding_system): Now static.
1065 2013-02-04 Eli Zaretskii <eliz@gnu.org>
1067 * xdisp.c (window_buffer_changed): region_showing can be negative,
1068 which still means region is being displayed.
1069 (redisplay_internal): Resurrect code that forced redisplay of the
1070 whole window when showing region and the mark has changed.
1071 Record the new mark position to allow redisplay optimizations.
1072 (display_line): If it->region_beg_charpos is non-zero, set the
1073 window's region_showing member to -1. (Bug#13623) (Bug#13626)
1075 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
1076 not bitfield of 1 bit.
1078 2013-02-03 Daniel Colascione <dancol@dancol.org>
1080 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
1081 daemon mode works on cygw32 when Emacs is installed and not just
1084 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
1086 Avoid file time stamp bug on MS-Windows (Bug#13149).
1087 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
1088 as FAT32 doesn't update time stamps when truncating them.
1089 Also, check that a file time stamp is not a multiple of 100 ns;
1090 this should catch all instances of the problem on MS-Windows,
1091 as its native file system resolution is 100 ns or worse, and
1092 checking for a non-multiple of 100 ns should impose only a small
1093 overhead on systems with ns resolution.
1095 2013-02-02 Eli Zaretskii <eliz@gnu.org>
1097 Avoid encoding file names on MS-Windows when they need to be run
1098 through dostounix_filename.
1099 * w32.c (normalize_filename): Accept an additional argument
1100 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
1101 downcase it even if w32-downcase-file-names is non-nil.
1102 (dostounix_filename): Accept an additional argument MULTIBYTE and
1103 pass it to normalize_filename.
1104 (emacs_root_dir): Adjust.
1106 * msdos.h (dostounix_filename): Adjust prototype.
1108 * w32.h (dostounix_filename): Adjust prototype.
1110 * msdos.c (dostounix_filename): Accept an additional argument and
1112 (init_environment): Adjust callers of dostounix_filename.
1114 * fileio.c (Ffile_name_directory, file_name_as_directory)
1115 (directory_file_name, Fexpand_file_name)
1116 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
1118 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
1120 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
1121 variables, as egetenv is case-insensitive for DOS_NT.
1123 * dired.c (file_name_completion): Don't call Fdirectory_file_name
1124 with an encoded file name.
1126 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name):
1127 Adjust calls to dostounix_filename.
1129 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
1131 * unexw32.c (unexec): Adjust call to dostounix_filename.
1133 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
1135 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
1138 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
1141 * callproc.c (Fcall_process): Make sure program name in PATH and
1142 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
1143 is passed to exec/spawnve, which fails unless the file-name
1146 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
1147 even if w32-quote-process-args is nil.
1149 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
1151 Fix timestamp bug when write-region appends nothing (Bug#13149).
1152 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
1153 the file's time stamp doesn't change if Emacs happens to write nothing
1154 to the file, and on a buggy file system this could cause Emacs to
1155 incorrectly infer that the file system doesn't have the bug.
1156 Avoid this problem by inhibiting the inference in this case.
1158 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
1160 * window.h (struct window): Convert base_line_number, base_line_pos
1161 and column_number_displayed members from Lisp_Object to ptrdiff_t.
1162 Convert region_showing member from Lisp_Object to bitfield.
1163 Remove sequence_number member. Adjust comments.
1164 * window.c (sequence_number): Remove.
1165 (make_window): Initialize column_number_displayed.
1166 * print.c (print_object): Follow the printed representation of
1167 frames and print window pointer to distinguish between windows.
1168 (adjust_window_count): Invalidate base_line_pos. Adjust comment.
1169 * xdisp.c (wset_base_line_number, wset_base_line_pos)
1170 (wset_column_number_displayed, wset_region_showing): Remove.
1171 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
1172 (try_scrolling, try_cursor_movement, redisplay_window)
1173 (try_window_reusing_current_matrix, try_window_id, display_line)
1174 (display_mode_lines, decode_mode_spec): Adjust users.
1175 * .gdbinit (pwinx): Do not print sequence_number.
1177 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
1179 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
1180 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
1181 * dired.c: Include <fcntl.h>.
1182 (open_directory): New function, which uses open and fdopendir
1183 rather than opendir. DOS_NT platforms still use opendir, though.
1184 (directory_files_internal, file_name_completion): Use it.
1185 (file_attributes): New function, with most of the old Ffile_attributes.
1186 (directory_files_internal, Ffile_attributes): Use it.
1187 (file_attributes, file_name_completion_stat): First arg is now fd,
1188 not dir name. All uses changed. Use fstatat rather than lstat +
1190 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
1191 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
1192 (emacs_readlinkat): New function, with much of the old
1193 Ffile_symlink_p, but with an fd argument for speed.
1194 It uses readlinkat rather than careadlinkatcwd, so that it
1195 need not assume the working directory.
1196 (Ffile_symlink_p): Use it.
1197 * filelock.c (current_lock_owner): Use emacs_readlinkat
1198 rather than emacs_readlink.
1199 * lisp.h (emacs_readlinkat): New decl.
1200 (READLINK_BUFSIZE, emacs_readlink): Remove.
1201 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
1202 (emacs_norealloc_allocator, emacs_readlink): Remove.
1203 This stuff is moved to fileio.c.
1204 * w32.c (fstatat, readlinkat): New functions.
1205 (careadlinkat): Don't check that fd == AT_FDCWD.
1206 (careadlinkatcwd): Remove; no longer needed.
1208 2013-01-31 Glenn Morris <rgm@gnu.org>
1210 * fileio.c (choose_write_coding_system): Make it callable from Lisp.
1211 (Fwrite_region): Update for new choose_write_coding_system args.
1212 Move the last piece of choose_write_coding_system here. (Bug#13522)
1213 (syms_of_fileio): Add choose-write-coding-system.
1215 2013-01-30 Eli Zaretskii <eliz@gnu.org>
1217 * w32.c (sys_open): Zero out the flags for the new file descriptor.
1218 (sys_close): Zero out the flags for the file descriptor before
1219 closing it. (Bug#13546)
1221 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
1222 (logon_network_drive, stat_worker, symlink, chase_symlinks):
1223 Use CharNextExA and CharPrevExA to iterate over file names encoded in
1226 * w32.c (w32_get_long_filename, init_environment, readlink):
1227 Support file names encoded in DBCS codepages.
1228 (readlink): Use the current file-name-coding-system, not the ANSI
1229 codepage, to decode and handle targets of symlinks.
1231 2013-01-28 Eli Zaretskii <eliz@gnu.org>
1233 * w32.c (opendir): Now accepts a 'const char *'.
1235 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>
1237 Remove obsolete redisplay code. See the discussion at
1238 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00576.html.
1239 * dispnew.c (preemption_period, preemption_next_check): Remove.
1240 (Vredisplay_preemption_period): Likewise.
1241 (update_frame, update_single_window, update_window, update_frame_1):
1242 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
1243 used, following the 2012-06-22 change.
1245 2013-01-25 Eli Zaretskii <eliz@gnu.org>
1247 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
1249 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>
1251 * font.c (num_fonts): Remove the leftover from old
1252 debugging code. Adjust comment style here and there.
1253 * insdel.c (insert_1): Remove.
1254 * lisp.h (insert_1): Remove prototype.
1255 * xdisp.c (message_dolog): Adjust users to call insert_1_both.
1257 2013-01-25 Eli Zaretskii <eliz@gnu.org>
1259 * w32.c (max_filename_mbslen): New function.
1260 (normalize_filename, readdir): Use it to detect locales where ANSI
1261 encoding of file names uses a double-byte character set (DBCS).
1262 If a DBCS encoding is used, advance by characters using
1263 CharNextExA, instead of incrementing a 'char *' pointer.
1264 Use _mbslwr instead of _strlwr. (Bug#13515)
1266 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
1267 request of memory reservation to 1.7GB. (Bug#13065)
1269 2013-01-25 Andreas Schwab <schwab@linux-m68k.org>
1271 * coding.c (detect_coding_iso_2022): Move back mis-reordered code
1272 at check_extra_latin label. (Bug#13505)
1274 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
1276 * nsfont.m (ns_escape_name, ns_unescape_name, ns_registry_to_script):
1277 Avoid redundant calls to strlen.
1279 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
1281 Drop async_visible and async_iconified fields of struct frame.
1282 This is possible because async input is gone; for details, see
1283 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
1284 * frame.h (struct frame): Remove async_visible and async_iconified
1285 members, convert garbaged to unsigned bitfield. Adjust comments.
1286 (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users.
1287 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
1288 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
1289 Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
1290 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
1292 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
1293 properly. Likewise for obscured.
1295 (handle_one_xevent): Save visible state to generate ICONIFY_EVENT
1298 (windowDidDeminiaturize): Generate DEICONIFY_EVENT.
1300 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
1302 * insdel.c (prepare_to_modify_buffer): Revert last change as suggested
1303 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
1305 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
1307 * xdisp.c (message2, message2_nolog): Remove functions.
1308 (message3, message3_nolog): Extract nbytes and multibyteness directly
1309 from the string. Change all callers.
1310 (message3_nolog): Don't set message_enable_multibyte since set_message
1311 will reset it anyway.
1312 (message1, message1_nolog): Use message3.
1313 (vmessage): Use a stack allocated buffer rather than f->message_buf.
1314 (with_echo_area_buffer): Remove last two arguments. Update all callers.
1315 (set_message): Drop all but the second arg, which has to be a string.
1316 (set_message_1): Simplify now that we know that a1 is NULL and the
1317 second arg is a string.
1318 * frame.h (struct frame): Remove `message_buf' field.
1319 Use glyphs_initialized_p instead.
1320 (FRAME_MESSAGE_BUF): Remove macro.

1322 * lisp.h (message2, message2_nolog): Remove declarations.
1323 (message3, message3_nolog): Update declarations.
1324 * keyboard.c (read_char_minibuf_menu_text)
1325 (read_char_minibuf_menu_width): Remove vars.
1326 (read_char_minibuf_menu_prompt): Rewrite the menu's construction so as
1327 to correctly handle multibyte strings.
1328 * frame.c (delete_frame): Don't free message_buf any more.
1329 * editfns.c (message_text, message_length): Remove vars.
1330 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
1331 * fileio.c (auto_save_error): Use message3 instead of message2.
1332 * dispnew.c (adjust_frame_message_buffer): Remove function.
1334 2013-01-23 Eli Zaretskii <eliz@gnu.org>
1336 * w32term.c (w32fullscreen_hook): Account correctly for the screen
1337 real estate used for the tool bar and the menu bar.
1339 2013-01-23 Dmitry Antipov <dmantipov@yandex.ru>
1341 * insdel.c (prepare_to_modify_buffer): Force redisplay if
1342 hidden buffer is prepared to modification (Bug#13164).
1344 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
1346 * window.h (struct window): Change window_end_valid member from
1347 Lisp_Object to a bitfield. Adjust comments.
1348 (wset_window_end_valid): Remove.
1349 * window.c (adjust_window_count): Clear window_end_valid.
1350 (Fwindow_end): Adjust user. Remove ancient #if 0 code.
1351 (Fwindow_line_height, set_window_buffer, Frecenter)
1352 (Fsplit_window_internal, Fdelete_other_windows_internal)
1353 (Fset_window_fringes, Fset_window_scroll_bars): Adjust users.
1354 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
1355 * xdisp.c (check_window_end, reconsider_clip_changes)
1356 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
1357 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
1358 (find_first_unchanged_at_end_row, try_window_id): Likewise.
1360 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
1362 * xdisp.c (mark_window_display_accurate): Simplify the loop
1363 assuming that the only one of vchild, hchild or buffer window
1364 slots is non-nil. Call mark_window_display_accurate_1 for
1365 the leaf windows only.
1366 (mark_window_display_accurate_1): Always assume leaf window.
1369 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
1371 * emacs.c (Qkill_emacs_hook): Now static.
1373 * fileio.c (Finsert_file_contents): Simplify.
1374 Remove unnecessary assignments and tests.
1376 2013-01-21 Eli Zaretskii <eliz@gnu.org>
1378 * w32.c (acl_set_file): Don't test for errors unless
1379 set_file_security returns FALSE. Avoids spurious errors when
1382 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
1384 * fileio.c (Finsert_file_contents): Revert code introduced at
1385 2013-01-18 in favor of the simpler and generally better fix.
1386 Save stack space by removing 'buffer' and reusing 'read_buf'
1389 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1391 * lisp.h (eabs): Define unconditionally (Bug#13419).
1392 The old "#if !defined (eabs)" was an unnecessary revenant of back
1393 when this macro was called "abs". Document 'eabs' better.
1395 2013-01-19 Glenn Morris <rgm@gnu.org>
1397 * fns.c (Frandom): Doc fix.
1399 2013-01-19 Eli Zaretskii <eliz@gnu.org>
1401 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
1402 segfault when there are lots of overlays.
1404 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
1405 when there are lots of overlays.
1406 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
1407 for the details and a way to reproduce.
1409 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1411 * fileio.c: Use O_APPEND to append.
1412 This corresponds better to the natural interpretation of "append",
1413 and avoids the need to open the output file twice, or to invoke
1414 lseek when APPEND is neither nil nor a number.
1415 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
1416 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
1417 file possibly twice, and lseeking to its end; this avoids the
1418 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
1419 at the same time: the combination is never needed and apparently
1420 it doesn't work with DOS_NT.
1422 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
1423 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
1425 Allow floating-point file offsets.
1426 Problem reported by Vitalie Spinu in
1427 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
1428 * fileio.c (emacs_lseek): Remove.
1429 (file_offset): New function.
1430 (Finsert_file_contents, Fwrite_region): Use it.
1432 2013-01-19 Chong Yidong <cyd@gnu.org>
1434 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
1435 aborting on Fsignal (Bug#13289).
1437 2013-01-19 Eli Zaretskii <eliz@gnu.org>
1439 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
1440 set_file_security as failure due to insufficient privileges.
1441 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
1442 (fstat): Return owner and group like 'stat' and 'lstat' do.
1444 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1446 Work around bug in CIFS and vboxsf file systems (Bug#13149).
1447 The bug was observed on Ubuntu operating inside a virtual machine,
1448 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
1449 The workaround introduces a race condition on non-buggy hosts,
1450 but it's an unlikely race and anyway there's a nearly identical
1451 nearby race that can't be fixed.
1452 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
1454 (Fwrite_region): Test for file system time stamp bug.
1455 (init_fileio): New function.

1467 * fileio.c (read_non_regular): Rename to read_contents.
1468 Free Lisp_Save_Value object used to pass parameters.
1469 (read_non_regular_quit): Rename to read_contents_quit.
1470 (Finsert_file_contents): Redesign internal file reading loop to adjust
1471 gap and end positions after each read and so help make_gap to work
1472 properly. Do not signal an I/O error too early and so do not leave
1473 not yet decoded characters in a buffer, which was the reason of
1474 redisplay crash. Use list2 to build return value. Adjust comments.
1476 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
1478 Close a race when statting and reading files (Bug#13149).
1479 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
1480 This avoids a race if the file is renamed between stat and open.
1481 This race is not the problem originally noted in Bug#13149;
1482 see <http://bugs.gnu.org/13149#73> and later messages in the thread.

1527 * lisp.h (XSAVE_POINTER, XSAVE_INTEGER): Change to allow
1528 extraction from any Lisp_Save_Value slot. Add type checking.

1581 * editfns.c (save_excursion_save): Pack everything within
1582 Lisp_Save_Value and so avoid xmalloc.
1583 (save_excursion_restore): Adjust to match new layout. Use free_misc
1584 because we do not allocate extra memory any more. Add eassert.

1871 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
1872 don't ENCODE_FILE them, and return a unibyte string if the input
1874 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
1875 don't assume the input strings will always be multibyte. If the
1876 input strings are multibyte, decode strings obtained from C
1879 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
1881 * lisp.h (toplevel): Add two notices to the comment about
1882 defining a new Lisp data type.
1883 * print.c (print_object): If Lisp_Save_Value object's pointer
1884 is the address of a memory area containing Lisp_Objects, try
1886 * alloc.c (valid_lisp_object_p): Adjust comment.
1888 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
1890 * keyboard.c (record_asynch_buffer_change): Initialize an event
1891 only if it's really needed.
1892 * frame.h (enum output_method): Remove output_mac member since
1893 it's a leftover from the deleted code.
1894 * frame.c (Fframep): Adjust user here ...
1895 * terminal.c (Fterminal_live_p): ... and here.
1896 * coding.c (Qmac): Now here because it's only used to denote
1897 end-of-line encoding type.
1898 (syms_of_coding): DEFSYM it.
1899 * frame.h (Qmac): Remove duplicated declaration.
1901 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
1903 * window.c (select_window_1): Now static, since it's used only here.
1905 2012-12-25 Eli Zaretskii <eliz@gnu.org>
1907 * window.c (window_body_cols): Subtract display margins from the
1908 window body width on TTYs as well. See
1909 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
1910 for the original report.
1912 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
1914 * xdisp.c (redisplay_window): Remove inner local variable
1915 because the outer shadowed one has the same meaning.
1916 * xterm.h (struct x_output): Remove toolbar_detached member since it's
1918 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
1919 (xg_create_tool_bar): Adjust users.
1921 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
1923 * buffer.h (BUF_COMPACT): New macro to follow the common style.
1924 * buffer.c (Fget_buffer_create): Use it to set compact field of
1925 struct buffer_text to avoid accessing an uninitialized value
1926 when compact_buffer is called for the first time.
1927 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
1928 (Fset_buffer_modified_p): Use buffer_window_count to check
1929 whether the buffer is displayed in some window.
1930 * xdisp.c (message_dolog): Likewise.
1932 2012-12-23 Eli Zaretskii <eliz@gnu.org>
1934 * w32.c (acl_set_file): If setting the file security descriptor
1935 fails, and the new DACL is identical to the existing one, silently
1936 return success. This fixes problems for users backing up their
1937 own files without having the necessary privileges for setting
1938 security descriptors.
1940 * w32proc.c (reader_thread): Do not index fd_info[] with negative
1942 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
1943 after WaitForSingleObject returns normally. This expedites reader
1944 thread shutdown when delete_child triggers it.
1945 (reap_subprocess): More accurate commentary for why we call
1946 delete_child only when cp->fd is negative.
1948 * w32.c (sys_close): Do not call delete_child on a subprocess
1949 whose handle is not yet closed. Instead, set its file descriptor
1950 to a negative value, so that reap_subprocess will call
1951 delete_child on that subprocess when its SIGCHLD arrives.
1952 This avoids closing handles used for communications between sys_select
1953 and reader_thread, which doesn't give sys_select a chance to
1954 notice that the process exited and invoke the SIGCHLD handler for
1957 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
1959 * nsfns.m (Fns_do_applescript): Run event loop until script has
1960 been executed (Bug#12969).
1961 (ns_run_ascript): Chech as_script for nil, set to nil after
1964 2012-12-22 Martin Rudalics <rudalics@gmx.at>
1966 * window.c (Fselect_window): Reword doc-string (Bug#13248).
1968 2012-12-22 Eli Zaretskii <eliz@gnu.org>
1970 * w32term.c (w32fullscreen_hook): New function.
1971 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
1973 2012-12-21 Eli Zaretskii <eliz@gnu.org>
1975 * fileio.c (Finsert_file_contents): Doc fix.
1977 * w32proc.c (new_child, delete_child, find_child_pid): For a
1978 subprocess, consider its slot being in use as long as its process
1979 handle (procinfo.hProcess) is not NULL. This avoids reusing the
1980 slot when a new process is started immediately after killing
1981 another one, without waiting enough time for the first process to
1982 be reaped and resources allocated for it be orderly freed.
1984 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
1986 2012-12-21 Chong Yidong <cyd@gnu.org>
1988 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
1990 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
1992 2012-12-21 Eli Zaretskii <eliz@gnu.org>
1994 * w32.c (get_name_and_id): Always pass NULL as the first argument
1995 of lookup_account_sid. Avoids crashes with UNC file names that
1996 refer to DFS domains, not to specific machine names. (Bug#12621)
1997 Remove now unused argument FNAME; all callers changed.
1998 (get_file_owner_and_group): Remove now unused argument FNAME; all
2001 2012-12-21 Chong Yidong <cyd@gnu.org>
2003 * editfns.c (Finsert_char): Since read-char-by-name now signals an
2004 error for invalid chars, don't check for a nil return value.
2006 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
2008 Avoid calls to CHAR_TO_BYTE if byte position is known.
2009 * editfns.c (make_buffer_string_both): Use move_gap_both.
2010 (Fbuffer_string): Use make_buffer_string_both.
2011 * marker.c (buf_charpos_to_bytepos): Convert to eassert.
2013 (buf_bytepos_to_charpos): Likewise.
2014 (charpos_to_bytepos): Remove.
2015 * fileio.c (Finsert_file_contents): Use move_gap_both.
2016 * search.c (Freplace_match): Likewise.
2017 * process.c (process_send_region): Likewise. Use convenient
2018 names for byte positions.
2019 * lisp.h (charpos_to_bytepos): Remove prototype.
2020 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
2021 * insdel.c (move_gap): Likewise.
2023 2012-12-20 Paul Eggert <eggert@cs.ucla.edu>
2025 * xdisp.c (redisplay_internal): Remove now-unused local.
2027 2012-12-20 Stefan Monnier <monnier@iro.umontreal.ca>
2029 * xdisp.c (select_frame_for_redisplay, ensure_selected_frame): Remove.
2030 (redisplay_internal): Don't bother selecting the frame to get the
2031 proper value of frame-local variables (bug#13225).
2033 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
2035 * textprop.c (set_text_properties_1): Do not allow NULL interval.
2036 Rename 4th argument since it may be buffer or string. Adjust comment.
2037 * intervals.c (graft_intervals_info_buffer): Find an interval here.
2039 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
2041 * coding.c (Fdetect_coding_region): Do not check start and end with
2042 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
2043 (code_convert_region): Likewise.
2045 2012-12-18 Eli Zaretskii <eliz@gnu.org>
2047 * w32.c (acl_get_file, acl_set_file): Run the file name through
2048 map_w32_filename, and resolve any symlinks in the file name, like
2050 (acl_set_file): Call revert_to_self, if any privileges were
2053 2012-12-17 Juanma Barranquero <lekktu@gmail.com>
2055 * makefile.w32-in ($(BLD)/editfns.$(O), $(BLD)/fileio.$(O))
2056 ($(BLD)/w32.$(O)): Update dependencies.
2058 2012-12-17 Stefan Monnier <monnier@iro.umontreal.ca>
2060 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
2061 propagate redisplay's scrolling (if any) to the right window.
2062 (redisplay_internal): Use ensure_selected_frame.
2063 (display_mode_lines): Complete last fix.
2064 * window.c (select_window_1): New func, extracted from select_window.
2065 (select_window): Use it.
2066 * window.h (select_window_1): Declare.
2068 2012-12-17 Eli Zaretskii <eliz@gnu.org>
2070 Emulate Posix ACL APIs on MS-Windows.
2071 * w32.c: Include sddl.h and sys/acl.h.
2072 (SDDL_REVISION_1): Define if not already defined.
2073 (g_b_init_get_security_descriptor_dacl)
2074 (g_b_init_convert_sd_to_sddl, g_b_init_convert_sddl_to_sd)
2075 (g_b_init_is_valid_security_descriptor)
2076 (g_b_init_set_file_security): New static flags.

2088 (acl_free, acl_get_file, acl_set_file): New functions.
2090 * fileio.c (Fcopy_file) [WINDOWSNT]: Support copying ACLs.
2092 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
2094 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
2095 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
2096 for some of that bug's symptoms can now cause Emacs to abort.
2097 Remove the workaround.
2098 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
2099 The bug that caused SIGCHLD to get lost has been fixed, and the
2100 workaround for it can now cause Emacs to abort.
2102 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
2104 * sysdep.c (emacs_abort): Bump backtrace size to 40.
2105 Companion to the 2012-09-30 patch. Suggested by Eli Zaretskii in
2106 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.
2108 2012-12-16 Romain Francoise <romain@orebokech.com>
2110 * fileio.c (Ffile_acl, Fset_file_acl): New functions.
2111 (Fcopy_file): Change last arg to `preserve_extended_attributes'
2112 and copy ACL entries of file in addition to SELinux context if set.
2113 (syms_of_fileio): Add `file-acl' and `set-file-acl'.
2115 * Makefile.in (LIBACL_LIBS): New macro.
2118 2012-12-15 Paul Eggert <eggert@cs.ucla.edu>
2120 * fileio.c (internal_delete_file): Use bool for boolean.
2122 2012-12-15 Eli Zaretskii <eliz@gnu.org>
2124 Fix bug #13079 on MS-Windows with temp files not being deleted.

2127 (register_child): First argument is now pid_t.
2128 (record_infile, record_pending_deletion): New prototypes.
2130 * w32proc.c (new_child): Initialize input_file and
2131 pending_deletion members of the child.
2132 (delete_child): Delete the child's temporary input file, if any,
2133 that is pending deletion.
2134 (register_child): First argument is now pid_t.
2135 (record_infile, record_pending_deletion): New functions.
2136 (reap_subprocess): Fix a typo in DebPrint string.
2137 (sys_spawnve, sys_kill): Use pid_t for PID arguments.
2139 * fileio.c (internal_delete_file): Return an int again: non-zero
2140 if delete-file succeeds, zero otherwise.
2142 * lisp.h (internal_delete_file): Adjust prototype.
2144 * callproc.c (Fcall_process): Don't overwrite infile with result
2146 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
2147 asynchronous subprocess, record the name of the input file name,
2149 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
2150 delete the file, record it as pending deletion when the subprocess
2153 2012-12-14 Eli Zaretskii <eliz@gnu.org>
2155 * editfns.c [HAVE_PWD_H]: Include grp.h.
2157 * makefile.w32-in ($(BLD)/editfns.$(O)): Add $(NT_INC)/grp.h.
2159 2012-12-14 Paul Eggert <eggert@cs.ucla.edu>
2161 Fix permissions bugs with setgid directories etc. (Bug#13125)
2162 * dired.c (Ffile_attributes): Return t as the 9th attribute,
2163 to mark it as a placeholder. The old value was often wrong.
2164 The only user of this attribute has been changed to use
2165 file-ownership-preserved-p instead, with its new group arg.
2166 * editfns.c (Fgroup_gid, Fgroup_real_gid): New functions.
2168 2012-12-14 Stefan Monnier <monnier@iro.umontreal.ca>

2173 2012-12-14 Eli Zaretskii <eliz@gnu.org>
2175 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
2176 try to get accurate owner and group information from NT file
2177 security APIs. This is to make most callers of 'stat' and
2178 'lstat', which don't need that information, much faster.
2180 * dired.c (Ffile_attributes) [WINDOWSNT]:
2181 Set w32_stat_get_owner_group to a non-zero value, to request accurate
2182 owner and group information from 'lstat'.
2184 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
2186 * fileio.c (Finsert_file_contents): Don't put tail into head area,
2187 as that confuses set-auto-coding, so insist on the head-read
2188 returning the full 1024 bytes. Let lseek compute the tail offset;
2189 less work for us. Do not ignore I/O errors when reading the tail.
2191 * xdisp.c: Minor style fixes.
2192 (init_iterator): Hoist assignment out of if-expression.
2193 (markpos_of_region): Callers now test for sign, not for -1.
2195 2012-12-13 Dmitry Antipov <dmantipov@yandex.ru>
2197 Minor redisplay optimization when the region length is zero.
2198 * xdisp.c (markpos_of_region): New function.
2199 (init_iterator): Do not highlight the region of zero length.
2200 (redisplay_window): Check whether the region is of non-zero length.
2201 (try_cursor_movement): Allow if the region length is zero.
2202 (try_window_reusing_current_matrix, try_window_id): Likewise.
2204 2012-12-13 Eli Zaretskii <eliz@gnu.org>
2206 * search.c (search_buffer): Check the inverse translations of each
2207 character in pattern when the buffer being searched is unibyte.
2210 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
2212 * fileio.c (Fvisited_file_modtime): Return (-1 ...) for nonexistent
2213 files, fixing a regression from 24.2.
2214 (Fverify_visited_file_modtime): Don't read uninitialized st.st_size.
2216 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
2218 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
2219 fstat shouldn't fail, and if it does fail copy-file should not proceed.
2220 Remove unnecessary S_ISLNK test, as (contra the comments) this
2221 function can't copy symlinks. Improve quality of error message
2222 when attempting to copy files that are neither regular files nor
2225 2012-12-12 Dmitry Antipov <dmantipov@yandex.ru>
2227 * dispnew.c (set_window_cursor_after_update): Use clip_to_bounds.

2229 * window.c (Frecenter):
2230 * xdisp.c (resize_mini_window, hscroll_window_tree, draw_glyphs):
2231 * xterm.c (x_set_toolkit_scroll_bar_thumb): Likewise.
2233 2012-12-12 Daniel Colascione <dancol@dancol.org>
2235 * unexcw.c (fixup_executable): Use posix_fallocate to ensure that
2236 the dumped Emacs is not a sparse file, greatly improving Cygwin
2237 "make bootstrap" performance.
2239 2012-12-11 Michael Albinus <michael.albinus@gmx.de>
2241 * inotify.c (inotify_callback): Generate an Emacs event for every
2242 incoming inotify event.
2244 2012-12-11 Eli Zaretskii <eliz@gnu.org>
2246 * xdisp.c (handle_face_prop): Fix logic of computing
2247 it->start_of_box_run_p.
2248 (append_space_for_newline): If the glyph row is R2L, reset the
2249 iterator's end_of_box_run_p flag before prepending the space glyph.
2250 (extend_face_to_end_of_line): If the glyph row is R2L, reset the
2251 iterator's start_of_box_run_p flag before prepending the stretch.
2252 (append_glyph, produce_image_glyph, append_composite_glyph)
2253 (append_stretch_glyph, append_glyphless_glyph): Reverse the
2254 left_box_line_p and right_box_line_p flags of the glyph for R2L
2255 glyph rows. (Bug#13011)
2257 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>
2259 * buffer.c (Fset_buffer_multibyte): Do not force redisplay
2260 if changed buffer is not shown in a window.
2261 * insdel.c (prepare_to_modify_buffer): Likewise.
2262 * window.c (replace_buffer_in_windows_safely): Do nothing
2263 if buffer is not shown in a window.

2267 2012-12-11 Eli Zaretskii <eliz@gnu.org>
2269 * inotify.c (Finotify_add_watch): Rename decoded_file_name to
2270 encoded_file_name, which is what it is.
2272 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>
2274 Consistently use marker_position and marker_byte_position.
2275 * fringe.c (Ffringe_bitmaps_at_pos):
2276 * indent.c (Fvertical_motion):
2277 * insdel.c (prepare_to_modify_buffer):

2282 * xdisp.c (message_dolog, with_echo_area_buffer_unwind_data)
2283 (mark_window_display_accurate_1, redisplay_window, decode_mode_spec):
2284 Replace direct access to marker fields with calls
2285 to marker_position and/or marker_byte_position.
2287 2012-12-11 Juanma Barranquero <lekktu@gmail.com>
2289 * makefile.w32-in (SIG2STR_H): New macro.
2290 (SYSWAIT_H, $(BLD)/emacs.$(O), $(BLD)/process.$(O))
2291 ($(BLD)/w32notify.$(O)): Update dependencies.
2293 2012-12-10 Daniel Colascione <dancol@dancol.org>

2296 Windows file notification functionality unless WINDOWSNT.
2298 * w32gui.h (hprevinst, lpCmdLine, nCmdShow): Remove unused
2301 * w32fns.c (cache_system_info): Initialize the global hinst
2302 variable here so various initialization calls DTRT.
2304 * unexw32.c (hprevinst, lpCmdLine, nCmdShow): Remove unused variables.
2305 (hinst): Remove unneeded extern declaration.
2306 (_start): Remove initialization of above variables; remove
2307 initialization of hinst, as cache_system_info now does that.
2309 * emacs.c (main): Call cache_system_info early in startup; we
2310 previously weren't calling it in Cygwin builds.
2312 * Makefile.in (ntsource, WINDRES, W32_RES, W#@_RES_LINK):
2313 Teach the autoconf build system how to compile a Windows resource file
2314 and link it to Emacs.

2327 and buffer_local_symbols.
2328 * window.h (buffer_shared): Remove declaration.
2329 (wset_buffer): Convert from inline ...
2330 * window.c (wset_buffer): ... to an ordinary function.
2331 (adjust_window_count): New function.
2332 (make_parent_window): Use it.

2337 2012-12-10 Eli Zaretskii <eliz@gnu.org>
2339 Support for filesystem notifications on MS-Windows.
2340 * w32proc.c (sys_select): If drain_message_queue returns non-zero,
2341 and this is a TTY frame, signal the caller that keyboard input is
2344 * w32xfns.c (drain_message_queue): Now returns an int: an

2418 2012-12-10 Fabrice Popineau <fabrice.popineau@gmail.com>
2420 * w32fns.c (cache_system_info): Cast sysinfo_cache.dwPageSize to
2421 DWORD_PTR, for compatibility with 64-bit builds.
2423 * w32.c (_PROCESS_MEMORY_COUNTERS_EX):

2449 * w32.c (unsetenv): Return 0 if the input string is too long.
2451 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
2453 Use putenv+unsetenv instead of modifying environ directly (Bug#13070).
2454 * alloc.c (xputenv): New function.
2455 * dbusbind.c (Fdbus_init_bus):
2457 * xterm.c (x_term_init):
2458 Use xputenv instead of setenv or putenv, to detect memory exhaustion.

2465 instead, use xputenv+unsetenv to set and restore TZ.
2466 (environbuf): Remove static var. All uses removed.

2468 no longer needed here.
2469 (set_time_zone_rule_tz1, set_time_zone_rule_tz2) [LOCALTIME_CACHE]:
2470 Move to inside set_time_zone_rule; they don't need file scope any more.
2471 (set_time_zone_rule): Maintain the TZ=value string separately.
2472 (syms_of_editfns): Don't initialize initial_tz;
2473 init_editfns now does it.
2474 * emacs.c (dump_tz) [HAVE_TZSET]: Now const.
2475 * lisp.h (xputenv): New decl.
2477 2012-12-08 Fabrice Popineau <fabrice.popineau@gmail.com>

2488 informative (Bug#12992).
2490 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
2492 Simplify get_lim_data.
2493 * vm-limit.c (get_lim_data): Combine RLIMIT_AS and RLIMIT_DATA methods.
2494 Remove USG and vlimit methods; no longer used these days.
2495 Add #error catchall just in case.
2497 Assume POSIX 1003.1-1988 or later for signal.h (Bug#13026).
2498 Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,
2499 SIGTTOU, SIGUSR1, SIGUSR2, as Microsoft platforms lack these.

2521 This will cause a production Emacs to dump core instead of
2524 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
2526 * frame.c (make_frame): Do not set window's buffer to t.
2527 * window.c (Fsplit_window_internal): Likewise. Previously it was
2528 used to indicate that the window is being set up. Now we use
2529 set_window_buffer for all new windows, so the condition in ...
2530 (Fset_window_buffer): ... is always true and can be removed.
2532 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
2534 Convenient macro to check whether the buffer is hidden.
2535 * buffer.h (BUFFER_HIDDEN_P): New macro.
2536 * frame.c (make_frame): Use it. Adjust comment.
2537 * buffer.c (candidate_buffer): New function.
2538 (Fother_buffer, other_buffer_safely): Use it.
2540 2012-12-06 Eli Zaretskii <eliz@gnu.org>
2542 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG

2544 loop and return zero. (Bug#13086)
2546 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
2548 * frame.h (x_char_width, x_char_height): Remove prototypes.

2561 Fix a recently-introduced delete-process race condition.
2562 * callproc.c, process.h (record_kill_process):
2563 New function, containing part of the old call_process_kill.
2564 (call_process_kill): Use it.
2565 This does not change call_process_kill's behavior.
2566 * process.c (Fdelete_process): Use record_kill_process to fix a
2567 race condition that could cause Emacs to lose track of a child.
2569 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
2571 Avoid code duplication between prev_frame and next_frame.
2572 * frame.c (candidate_frame): New function. Add comment.
2573 (prev_frame, next_frame): Use it. Adjust comment.
2575 2012-12-06 Eli Zaretskii <eliz@gnu.org>
2577 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
2578 fails, signal an error instead of continuing with an empty
2580 Encode expanded temp file pattern before passing it to mkstemp or
2583 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
2584 Encode the file name before passing it to dostounix_filename, in
2585 case it will downcase it (under w32-downcase-file-names).
2588 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
2590 Minor call-process cleanups.
2591 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
2592 at the same time as other platforms, to simplify analysis.
2593 No need for fd0_volatile since we have synch_process_fd.
2594 Avoid needless emacs_close; arg is always negative.
2596 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
2598 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
2601 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
2603 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
2604 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
2605 and mouse_face_hidden members to a bitfields.
2606 * frame.h (struct frame): Remove set-but-not-used space_width member.
2607 (FRAME_SPACE_WIDTH): Remove.
2608 * nsterm.m, w32term.c, xterm.c: Adjust users.
2609 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
2610 member. Adjust users. Convert term_initted, delete_in_insert_mode,
2611 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
2612 members to a bitfields.
2614 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
2616 Don't let call-process be a zombie factory (Bug#12980).
2617 Fixing this bug required some cleanup of the signal-handling code.
2618 As a side effect, this change also fixes a longstanding rare race
2619 condition whereby Emacs could mistakenly kill unrelated processes,
2620 and it fixes a bug where a second C-g does not kill a recalcitrant
2621 synchronous process in GNU/Linux and similar platforms.
2622 The patch should also fix the last vestiges of Bug#9488,
2623 a bug which has mostly been fixed on the trunk by other changes.
2624 * callproc.c, process.h (synch_process_alive, synch_process_death)
2625 (synch_process_termsig, sync_process_retcode):
2626 Remove. All uses removed, to simplify analysis and so that
2627 less consing is done inside critical sections.
2628 * callproc.c (call_process_exited): Remove. All uses replaced
2629 with !synch_process_pid.
2630 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
2631 These take the role of what used to be in unwind-protect arg.
2633 (block_child_signal, unblock_child_signal):
2634 New functions, to avoid races that could kill innocent-victim processes.
2635 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
2636 (call_process_kill): Record killed processes as deleted, so that
2637 zombies do not clutter up the system. Do this inside a critical
2638 section, to avoid a race that would allow the clutter.
2639 (call_process_cleanup): Fix code so that the second C-g works again
2640 on common platforms such as GNU/Linux.
2641 (Fcall_process): Create the child process in a critical section,
2642 to fix a race condition. If creating an asynchronous process,
2643 record it as deleted so that zombies do not clutter up the system.
2644 Do unwind-protect for WINDOWSNT too, as that's simpler in the
2645 light of these changes. Omit unnecessary call to emacs_close
2646 before failure, as the unwind-protect code does that.
2647 * callproc.c (call_process_cleanup):
2648 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
2649 * process.c (record_deleted_pid): New function, containing
2650 code refactored out of Fdelete_process.
2651 (Fdelete_process): Use it.
2652 (process_status_retrieved): Remove. All callers changed to use
2653 child_status_change.
2654 (record_child_status_change): Remove, folding its contents into ...
2655 (handle_child_signal): ... this signal handler. Now, this
2656 function is purely a handler for SIGCHLD, and is not called after
2657 a synchronous waitpid returns; the synchronous code is moved to
2658 wait_for_termination. There is no need to worry about reaping
2659 more than one child now.
2660 * sysdep.c (get_child_status, child_status_changed): New functions.
2661 (wait_for_termination): Now takes int * status and bool
2662 interruptible arguments, too. Do not record child status change;
2663 that's now the caller's responsibility. All callers changed.
2664 Reimplement in terms of get_child_status.
2665 (wait_for_termination_1, interruptible_wait_for_termination):
2666 Remove. All callers changed to use wait_for_termination.
2667 * syswait.h: Include <stdbool.h>, for bool.
2668 (record_child_status_change, interruptible_wait_for_termination):
2670 (record_deleted_pid, child_status_changed): New decls.
2671 (wait_for_termination): Adjust to API changes noted above.
2673 * bytecode.c, lisp.h (Qbytecode): Remove.
2674 No longer needed after 2012-11-20 interactive-p changes.
2676 2012-12-03 Eli Zaretskii <eliz@gnu.org>
2678 * xdisp.c (redisplay_window): If the cursor is visible, but inside
2679 the scroll margin, move point outside the margin. (Bug#13055)
2681 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
2683 * gtkutil.c (my_log_handler): New function.
2684 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
2686 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
2688 * lisp.h (modify_region): Rename to...
2689 (modify_region_1): ...new prototype.
2690 * textprop.c (modify_region): Now static. Adjust users.
2691 * insdel.c (modify_region): Rename to...
2692 (modify_region_1): ...new function to work with current buffer.
2693 Adjust comment and users. Use true and false for booleans.
2695 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
2697 * alloc.c (free_save_value): New function.
2698 (safe_alloca_unwind): Use it.
2699 * lisp.h (free_save_value): New prototype.
2700 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
2702 (save_excursion_restore): Adjust to match saved data structure.
2703 Use free_save_value to offload some work from GC. Drop obsolete
2706 2012-12-03 Chong Yidong <cyd@gnu.org>
2708 * fileio.c (Vauto_save_list_file_name): Doc fix.
2710 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
2712 * w32fns.c: Remove prototype of atof.
2713 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
2715 (file_dialog_callback): Make it UINT_PTR.
2717 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
2720 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
2721 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
2724 2012-12-03 Glenn Morris <rgm@gnu.org>
2726 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
2728 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
2730 Fix xpalloc confusion after memory is exhausted.
2731 * alloc.c (xpalloc): Comment fix.
2732 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
2733 and signals an error, do not clear charset_table_size, as
2734 charset_table is still valid.
2735 * doprnt.c (evxprintf): Clear *BUF after freeing it.
2737 Use execve to avoid need to munge environ (Bug#13054).
2738 * callproc.c (Fcall_process):
2739 * process.c (create_process):
2740 Don't save and restore environ; no longer needed.
2741 * callproc.c (child_setup):
2742 Use execve, not execvp, to preserve environ.
2744 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
2746 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
2748 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2750 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
2751 display for sliced images (Bug#10500).

2755 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
2757 * doc.c (Fdocumentation): Re-add handling of function-documentation,
2758 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
2760 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
2762 * xdisp.c (window_outdated): Remove eassert since it hits
2763 some suspicious corner cases (see Bug#13007 and Bug#13012).
2764 (mode_line_update_needed): New function.
2765 (redisplay_internal, redisplay_window): Use it.

2768 (redisplay_internal): Move comment about buffer_shared...
2769 (buffer_shared_and_changed): ...near to its real use.
2771 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
2773 * callproc.c (Fcall_process): Don't misreport vfork failure.
2775 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
2777 * callproc.c (Fcall_process): Fix vfork portability problems.
2778 Do not assume that fd[0], count, filefd, and save_environ survive
2779 vfork. Fix bug whereby wrong errno value could be reported for
2780 pipe failure. Some minor cleanups, too, as follows. Move buf and
2781 bufsize to the context where they're needed. Change new_argv to
2782 be of type char **, as this is more convenient and avoids casts.
2783 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
2784 Now local constants, not macros.
2786 2012-11-18 Kenichi Handa <handa@gnu.org>

2812 * unexcoff.c (write_segment): Assume EFAULT is defined.
2814 2012-11-27 Eli Zaretskii <eliz@gnu.org>
2816 * fontset.c (Finternal_char_font): Return nil on non-GUI frames.
2819 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
2820 highlighting on the frame was cleared. Prevents assertion
2821 violations when repeatedly clicking on the "Top" link of the
2822 "bread-crumbs" in Info buffers.
2824 2012-11-25 Paul Eggert <eggert@cs.ucla.edu>
2826 * sysdep.c (sys_subshell): Don't assume pid_t fits in int.
2828 2012-11-24 Ken Brown <kbrown@cornell.edu>
2830 * keyboard.c (HAVE_MOUSE):
2831 * frame.c (HAVE_MOUSE): Remove, and rewrite code as if HAVE_MOUSE
2832 were always defined.
2834 2012-11-24 Eli Zaretskii <eliz@gnu.org>
2836 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
2837 between bpos_covered and bpos_max. This fixes cursor display when
2838 several display strings follow each other.
2840 * .gdbinit (pgx): If the glyph's object is a string, display the
2841 pointer to string data, rather than the value of the string object
2842 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
2844 * indent.c (Fvertical_motion): If the starting position is covered
2845 by a display string, return to one position before that, to avoid
2846 overshooting it inside move_it_to. (Bug#12930)
2848 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
2850 * frame.h (struct frame): Remove display_preempted member
2851 since all users are dead long ago.
2852 * nsterm.h (struct x_output): Use the only dummy member.
2853 * w32menu.c (pending_menu_activation): Remove since not
2855 (set_frame_menubar): Adjust user.
2856 * w32term.h (struct x_output): Drop outdated #if 0 code.
2857 (struct w32_output): Use bitfields for explicit_parent,
2858 asked_for_visible and menubar_active members.
2859 Drop unused pending_menu_activation member.
2860 * xterm.h (struct x_output): Drop outdated #if 0 code.
2861 Use bitfields for explicit_parent, asked_for_visible,
2862 has_been_visible and net_wm_state_hidden_seen members.
2864 2012-11-23 Eli Zaretskii <eliz@gnu.org>
2866 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
2867 of a literal "/". (Bug#12955)
2868 (gl-stamp): Invoke fc.exe directly, not through cmd.
2870 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>
2872 Assume POSIX 1003.1-1988 or later for dirent.h (Bug#12958).
2873 * dired.c: Assume HAVE_DIRENT_H.
2874 (NAMLEN): Remove, replacing with ...
2875 (dirent_namelen): New function. All uses changed. Use the GNU macro
2876 _D_EXACT_NAMELEN if available, as it's faster than strlen.
2877 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
2878 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
2879 * makefile.w32-in (DIR_H): Remove. All uses replaced with
2881 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
2882 * ndir.h: Rename to ../nt/inc/dirent.h.
2883 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
2884 Do not include <dirent.h>; no longer needed.
2885 * w32.c: Include <dirent.h> rather than "ndir.h".
2887 2012-11-23 Chong Yidong <cyd@gnu.org>
2889 * xftfont.c (xftfont_open): Remove duplicate assignment.
2891 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
2893 * alloc.c (Fgarbage_collect): Unblock input after clearing
2894 gc_in_progress to avoid note_mouse_highlight glitch with GC.
2895 * frame.h (FRAME_MOUSE_UPDATE): New macro.
2896 * msdos.c (IT_frame_up_to_date): Use it here...
2897 * w32term.c (w32_frame_up_to_date): ...here...
2898 * xterm.c (XTframe_up_to_date): ...and here...
2899 * nsterm.m (ns_frame_up_to_date): ...but not here.
2900 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
2902 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
2903 Do not check whether GC is in progress.
2905 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
2907 * xdisp.c (window_buffer_changed): New function.
2908 (update_menu_bar, update_tool_bar): Use it to
2909 simplify large 'if' statements.
2910 (redisplay_internal): Generalize commonly used
2911 'tail' and 'frame' local variables.
2913 2012-11-22 Eli Zaretskii <eliz@gnu.org>
2915 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
2916 with Windows system header.
2918 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
2920 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
2921 * alloc.c: Assume unistd.h exists.
2922 * fileio.c (Fexpand_file_name) [DOS_NT]: Use getcwd, not getwd.
2923 * sysdep.c (get_current_dir_name): Assume getcwd exists.
2924 (getwd) [USG]: Remove; no longer needed.
2925 (sys_subshell) [DOS_NT]: Use getcwd, not getwd.
2926 * w32.c (getcwd): Rename from getwd, and switch to getcwd's API.
2927 * w32.h (getcwd): Remove decl.
2929 2012-11-21 Stefan Monnier <monnier@iro.umontreal.ca>
2931 * xdisp.c (fast_set_selected_frame): Rename from update_tool_bar_unwind.
2932 Make it set selected_window as well.
2933 (update_tool_bar): Use it.
2935 2012-11-21 Ken Brown <kbrown@cornell.edu>
2937 * emacs.c (main): Set the G_SLICE environment variable for all
2938 Cygwin builds, not just GTK builds. See
2939 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
2941 2012-11-21 Eli Zaretskii <eliz@gnu.org>
2943 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
2944 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
2945 Define for the MSVC compiler.
2947 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
2949 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
2950 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
2951 dostounix_filename. Prevents crashes down the road, because
2952 dostounix_filename assumes it gets a unibyte string.
2953 Reported by Michel de Ruiter <michel@sentient.nl>, see
2954 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html
2956 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
2958 Conflate Qnil and Qunbound for `symbol-function'.
2959 * alloc.c (Fmake_symbol): Initialize `function' to Qnil.
2960 * lread.c (init_obarray): Set `function' fields to Qnil.
2961 * eval.c (Fcommandp): Ignore Qunbound.
2962 (Fautoload, eval_sub, Fapply, Ffuncall, Fmacroexpand):
2963 * data.c (Ffset, Ffboundp, indirect_function, Findirect_function):
2964 Test NILP rather than Qunbound.
2965 (Ffmakunbound): Set to Qnil.
2966 (Fsymbol_function): Never signal an error.
2967 (Finteractive_form): Ignore Qunbound.
2969 2012-11-20 Paul Eggert <eggert@cs.ucla.edu>
2971 * eval.c (interactive_p): Remove no-longer-used decl.
2973 2012-11-20 Dmitry Antipov <dmantipov@yandex.ru>
2975 * xdisp.c (buffer_shared): Adjust comment.
2976 (buffer_shared_and_changed): New function.
2977 (prepare_menu_bars, redisplay_internal): Use it to
2978 decide whether all windows or frames should be updated.
2979 (window_outdated): New function.
2980 (text_outside_line_unchanged_p, redisplay_window): Use it.
2981 (redisplay_internal): Likewise. Fix indentation.
2983 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
2985 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
2986 (syms_of_eval): Remove corresponding defsubr.
2987 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
2989 2012-11-19 Daniel Colascione <dancol@dancol.org>
2991 * w32fns.c (Fx_file_dialog):
2992 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
2993 cygwin_convert_file_name*.
2995 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
2996 Rename cygwin_convert_path* to cygwin_convert_file_name*.
2998 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
3000 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
3002 2012-11-18 Eli Zaretskii <eliz@gnu.org>
3004 * w32select.c: Include w32common.h before w32term.h, so that
3005 windows.h gets included before w32term.h uses some of its
3006 features, see below.
3008 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
3010 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
3012 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
3014 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
3016 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
3017 (ns_select): Return at once if events are held (Bug#12834).
3019 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
3021 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
3022 Needed following 2012-10-20 change. (Bug#12902)
3024 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
3026 * w32proc.c (waitpid): Remove unused label get_result.
3028 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
3030 * makefile.w32-in (SYSWAIT_H): New macro.
3031 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
3032 ($(BLD)/sysdep.$(O)): Update dependencies.
3034 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
3036 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
3037 * callproc.c (relocate_fd): Assume F_DUPFD.
3038 * emacs.c, term.c (O_RDWR): Remove.
3039 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
3040 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
3041 * nsterm.m: Assume <fcntl.h> exists.
3042 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
3043 (create_pty, Fmake_network_process, server_accept_connection)
3044 (wait_reading_process_output, init_process_emacs):
3046 (wait_reading_process_output): Put in a special case for WINDOWSNT
3047 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
3048 It's not clear this is needed, but it's a more-conservative change.
3049 (create_process): Assume FD_CLOEXEC.
3050 (create_process, create_pty): Assume O_NOCTTY.
3051 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
3052 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
3053 Omit if not DOS_NT, since F_GETFL is not defined there.
3054 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
3055 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
3057 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
3058 lack it, since gnulib guarantees this.
3059 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
3061 2012-11-17 Eli Zaretskii <eliz@gnu.org>
3063 * w32.c (faccessat): Pretend that directories have the execute bit
3064 set. Emacs expects that, e.g., in files.el:cd-absolute.
3066 * w32proc.c (create_child): Don't clip the PID of the child
3067 process to fit into an Emacs integer, as this is no longer a
3069 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
3070 reaping only the process specified by PID argument, if that is
3071 positive. Use PID instead of dead_child to know which process to
3072 reap. Wait for the child to die only if WNOHANG is not in
3074 (sys_select): Don't set dead_child.
3076 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
3077 as it is no longer needed.
3079 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
3081 (record_child_status_change): Remove the setting of
3082 record_at_most_one_child for the !WNOHANG case.
3084 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
3086 Fix problems in ns port found by static checking.
3087 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
3088 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
3089 not to process group.
3090 (ns_select): Use emacs_write, not write, as that's more robust
3091 in the presence of signals.
3092 (fd_handler:): Check for read errors.
3094 2012-11-16 Glenn Morris <rgm@gnu.org>
3096 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
3098 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
3100 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
3102 2012-11-16 Eli Zaretskii <eliz@gnu.org>
3104 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
3105 use the same value of thread handle.
3106 (start_timer_thread): If the timer thread exited (due to error),
3107 clean up by closing the two handles it used. Duplicate the caller
3108 thread's handle here, so it gets duplicated only once, when
3109 launching the timer thread. Set priority of the timer thread, not
3111 (getitimer): Don't duplicate the caller thread's handle here.
3114 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
3116 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
3119 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
3121 Remove no-longer-used pty_max_bytes variable.
3122 * process.c (pty_max_bytes): Remove; unused.
3123 (send_process): Do not set it.
3125 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
3127 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
3128 Update dependencies.
3130 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
3132 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
3133 This follows up on the 2012-09-29 patch that removed indirection
3134 for the 'function' field. Reported by Sergey Vinokurov in
3135 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
3137 2012-11-14 Eli Zaretskii <eliz@gnu.org>
3139 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
3140 different name, as the MS runtime does not have such a function,
3141 and probably never will.) All callers changed. Ignore DIRFD
3142 value if PATH is an absolute file name, to match Posix spec
3143 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
3146 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
3148 * xdisp.c (echo_area_display, redisplay_internal):
3149 Omit redundant check whether frame_garbaged is set.
3151 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
3153 Use faccessat, not access, when checking file permissions (Bug#12632).
3154 This fixes a bug that has been present in Emacs since its creation.
3155 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
3156 which must set some sort of record. (Torek's bug report was against
3157 a predecessor of GNU Emacs, but GNU Emacs happened to have the
3158 same common flaw.) See Torek's Usenet posting
3159 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
3160 Posted: Fri Apr 8 14:18:56 1983.
3161 * Makefile.in (LIB_EACCESS): New macro.
3163 * callproc.c (init_callproc):
3164 * charset.c (init_charset):
3165 * fileio.c (check_existing, check_executable, check_writable)
3167 * lread.c (openp, load_path_check):
3168 * process.c (allocate_pty):
3170 Use effective UID when checking permissions, not real UID.
3171 * callproc.c (init_callproc):
3172 * charset.c (init_charset):
3173 * lread.c (load_path_check, init_lread):
3174 Test whether directories are accessible, not merely whether they exist.
3175 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
3176 * fileio.c (check_existing, check_executable, check_writable)
3178 Use symbolic names instead of integers for the flags, as they're
3180 (check_writable): New arg AMODE. All uses changed.
3181 Set errno on failure.
3182 (Ffile_readable_p): Use faccessat, not stat + open + close.
3183 (Ffile_writable_p): No need to call check_existing + check_writable.
3184 Just call check_writable and then look at errno. This saves a syscall.
3185 dir should never be nil; replace an unnecessary runtime check
3186 with an eassert. When checking the parent directory of a nonexistent
3187 file, check that the directory is searchable as well as writable, as
3188 we can't create files in unsearchable directories.
3189 (file_directory_p): New function, which uses 'stat' on most platforms
3190 but faccessat with D_OK (for efficiency) if WINDOWSNT.
3191 (Ffile_directory_p, Fset_file_times): Use it.
3192 (file_accessible_directory_p): New function, which uses a single
3193 syscall for efficiency.
3194 (Ffile_accessible_directory_p): Use it.
3195 * xrdb.c (file_p): Use file_directory_p.
3196 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
3197 * lread.c (openp): When opening a file, use fstat rather than
3198 stat, as that avoids a permissions race. When not opening a file,
3199 use file_directory_p rather than stat.
3200 (dir_warning): First arg is now a usage string, not a format.
3201 Use errno. All uses changed.
3202 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
3203 that merely introduced a race.
3204 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
3205 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
3206 and similarly for the other O_* flags.
3207 * w32.c (sys_faccessat): Rename from sys_access and switch to
3208 faccessat's API. All uses changed.
3209 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
3210 (magic_db): Rename from magic_file_p.
3211 (magic_db, search_magic_path): Return an XrmDatabase rather than a
3212 char *, so that we don't have to test for file existence
3213 separately from opening the file for reading. This removes a race
3214 fixes a permission-checking problem, and simplifies the code.
3216 (file_p): Remove; no longer needed.
3218 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
3220 Omit glyphs initialization at startup.
3221 * dispnew.c (glyphs_initialized_initially_p): Remove.
3222 (adjust_frame_glyphs_initially): Likewise. Adjust users.
3223 (Fredraw_frame): Move actual code from here...
3224 (redraw_frame): ...to here. Add eassert. Adjust comment.
3225 (Fredraw_display): Use redraw_frame.
3226 * xdisp.c (clear_garbaged_frames): Likewise.
3228 2012-11-13 Eli Zaretskii <eliz@gnu.org>
3230 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
3231 passed to pint2str and pint2hrstr to be at most the size of the
3232 frame's decode_mode_spec_buffer. This avoids crashes with very
3233 large values of FIELD_WIDTH argument to decode_mode_spec.
3236 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
3238 Fix a race with verify-visited-file-modtime (Bug#12863).
3239 Since at least 1991 Emacs has ignored an mtime difference of no
3240 more than one second, but my guess is that this was to work around
3241 file system bugs that were fixed long ago. Since the race is
3242 causing problems now, let's remove that code.
3243 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
3244 whose time stamp is off by no more than a second. Insist that the
3245 file time stamps match exactly.
3247 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
3249 * frame.h (struct frame): Convert external_tool_bar member to
3250 1-bit unsigned bitfield.
3251 * termhooks.h (struct terminal): Remove mouse_moved member since
3252 all users are long dead. Adjust comment on mouse_position_hook.
3254 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
3256 Simplify by using FOR_EACH_FRAME here and there.
3257 * frame.c (next_frame, prev_frame, other_visible_frames)
3258 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
3259 * w32term.c (x_window_to_scroll_bar): Likewise.
3260 * window.c (window_list): Likewise.
3261 * xdisp.c (x_consider_frame_title): Likewise.

3271 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
3273 * data.c (Qdefalias_fset_function): Now static.
3275 Another tweak to vectorlike_header change.

3278 (next_in_free_list, set_next_in_free_list):
3279 New functions, which respect C's aliasing rules better.
3281 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
3283 * window.c (list4i): Rename from 'quad'. All uses changed.
3284 Needed because <sys/types.h> defines 'quad' on Solaris 10.

3298 2012-11-10 Eli Zaretskii <eliz@gnu.org>
3300 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
3301 amount when the scroll margins are too large. When scrolling
3302 backwards in the buffer, give up if cannot reach point or the
3303 scroll margin within a reasonable number of screen lines.
3304 Fixes point position in window under scroll-up/down-aggressively when
3305 point is positioned many lines beyond the window top/bottom.
3308 * ralloc.c (relinquish): If real_morecore fails to return memory
3309 to the system, don't crash; instead, leave the last heap
3310 unchanged and return. (Bug#12774)

3331 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
3333 Fix recently introduced crash on MS-Windows (Bug#12839).
3334 * w32term.h (struct scroll_bar): Use convenient header.
3335 (SCROLL_BAR_VEC_SIZE): Remove.
3336 * w32term.c (x_scroll_bar_create): Use VECSIZE.
3338 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
3340 Tweak last vectorlike_header change.
3341 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
3342 vectorlike object on the free list. This is introduced to avoid
3343 some (but not all) pointer casting and aliasing problems, see
3344 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
3345 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike

3349 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
3351 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
3352 been removed, so remove them here also.

3356 * doc.c (Fdocumentation): Handle new property
3357 dynamic-docstring-function to replace the old ad-advice-info.

3363 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3365 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
3366 * fns.c (hashfn_eq, hashfn_eql, sxhash):
3367 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.

3374 * lisp.h (sxhash_combine): New inline function, with the contents
3375 of the old SXHASH_COMBINE.

3377 special hash function containing a comparison that always yields 1.
3379 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3381 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
3382 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
3383 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
3386 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
3388 * image.c (xpm_make_color_table_h): Fix compiler error because
3389 make_hash_table changed.
3391 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
3393 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
3395 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3397 Use ad-hoc comparison function for the profiler's hash-tables.
3398 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
3399 (make_log): Use them.
3400 (handle_profiler_signal): Don't inhibit quit any longer since we don't
3401 call Fequal any more.

3410 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
3411 (hash_lookup, hash_remove_from_table): Move assertion checking of
3412 hashfn result here. Check hash-equality before calling cmpfn.

3414 (hashtest_eq, hashtest_eql, hashtest_equal): New structs.
3415 (syms_of_fns): Initialize them.

3425 value of w32-scroll-lock-modifier is neither nil nor one of the
3426 known key modifiers. (Bug#12806)
3428 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
3430 Shrink struct vectorlike_header to the only size field.
3431 * lisp.h (enum pvec_type): Avoid explicit enum member values.
3433 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
3434 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
3435 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
3436 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
3437 information from the vector header. Adjust comment.

3452 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
3453 (large_vectors): Change type to struct large_vector.
3454 (allocate_vector_from_block): Simplify.
3455 (PSEUDOVECTOR_NBYTES): Replace with...
3456 (vector_nbytes): ...new function. Adjust users.
3457 (sweep_vectors): Adjust processing of large vectors.
3458 (allocate_vectorlike): Likewise.
3459 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
3460 Add easserts. Adjust XSETPVECTYPESIZE usage.
3461 (allocate_buffer): Use BUFFER_PVEC_INIT.
3462 (live_vector_p): Adjust to match large vector.
3463 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
3464 * buffer.h (struct buffer): Add next member.
3465 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
3467 (FOR_EACH_BUFFER): Adjust to match struct buffer change.
3468 * fns.c (internal_equal): Adjust to match enum pvec_type change.

3473 (xvecsize): New command.
3475 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
3477 * keyboard.c (event_to_kboard): Do not dereference
3478 frame_or_window field of SELECTION_REQUEST_EVENT
3479 and SELECTION_CLEAR_EVENT events (Bug#12814).
3480 * xterm.h (struct selection_input_event): Adjust comment.
3482 2012-11-07 Eli Zaretskii <eliz@gnu.org>
3484 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
3485 such as Scroll Lock, if the respective keys are treated as
3486 function keys, not as modifiers. This avoids destroying non-ASCII
3487 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
3489 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
3491 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
3493 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
3495 Restore some duplicate definitions (Bug#12814).
3496 This undoes part of the 2012-11-03 changes. Some people build
3497 with plain -g rather than with -g3, and they need the duplicate
3498 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
3499 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
3500 Define as macros, as well as as enums or as constants.
3502 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
3504 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
3505 to keypad keys (Bug#12816).
3507 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
3509 Minor adjustments of recently-changed frame functions.
3510 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
3511 known to be a frame (we're in the FRAMEP branch).
3512 * lisp.h (Qframep): Remove decl. frame.h declares this.
3513 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
3514 since they're meant for Lisp fixnum values.
3516 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3518 * window.c (Fwindow_combination_limit): Revert to the only
3519 required argument and adjust docstring as suggested in
3520 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
3521 by Martin Rudalics <rudalics@gmx.at>.
3523 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3525 Widely used frame validity and checking functions.
3526 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
3527 * frame.c (decode_live_frame, decode_any_frame): New functions.
3528 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
3529 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
3530 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)
3531 (Fframe_pointer_visible_p): Use decode_any_frame.

3533 (Fraise_frame, Flower_frame, Fmodify_frame_parameters)
3534 (Fset_frame_height, Fset_frame_width): Use decode_live_frame.
3535 (Fframe_focus): Likewise. Allow zero number of arguments.
3537 (frame_buffer_list, frame_buffer_predicate): Remove.
3538 * lisp.h (frame_buffer_predicate): Remove prototype.
3539 * buffer.c (Fother_buffer): Use decode_any_frame.
3540 * xdisp.c (Ftool_bar_lines_needed): Likewise.
3541 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
3542 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
3543 (Fclose_font, Ffont_info): Use decode_live_frame.
3544 * fontset.c (check_fontset_name): Likewise.
3545 * terminal.c (Fframe_terminal): Likewise.
3546 * w32fns.c (check_x_frame): Likewise.
3547 * window.c (Fminibuffer_window, Fwindow_at)
3548 (Fcurrent_window_configuration): Likewise.
3549 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
3550 Likewise. Allow zero number of arguments. Adjust docstring.
3551 * dispnew.c (Fredraw_frame): Likewise.
3552 * xfaces.c (frame_or_selected_frame): Remove.
3553 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
3554 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
3555 (Fframe_face_alist): Use decode_live_frame.
3556 * xfns.c (check_x_frame): Likewise.
3558 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3560 * window.c (quad): New function.
3561 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
3562 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
3563 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
3564 (Fwindow_line_height): Use it.
3565 (Fwindow_fringes): Use list3.
3566 (Fwindow_scroll_bars): Use list4.
3567 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
3568 (Fwindow_combination_limit): Allow zero number of arguments.
3570 2012-11-05 Eli Zaretskii <eliz@gnu.org>
3572 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
3574 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
3575 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
3576 file descriptor 2 for standard error. (Bug#12805)
3578 2012-11-05 Chong Yidong <cyd@gnu.org>
3580 * process.c (wait_reading_process_output): Revert previous change.
3582 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
3584 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
3585 This removes code that has been obsolete since around 1990.
3586 * callproc.c (Fcall_process):
3588 * process.c (create_process):
3589 * term.c (dissociate_if_controlling_tty):
3590 Assume setsid exists.
3591 * callproc.c (child_setup): Assume setpgid exists and behaves as
3592 per POSIX.1-1988 or later.
3593 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
3594 * emacs.c (shut_down_emacs):
3595 * sysdep.c (sys_suspend, init_foreground_group):
3596 Assume getpgrp behaves as per POSIX.1-1998 or later.
3597 * msdos.c (setpgrp): Remove.
3598 (tcgetpgrp, setpgid, setsid): New functions.
3599 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
3600 * term.c (no_controlling_tty): Remove; unused.
3601 * w32proc.c (setpgrp): Remove.
3602 (setsid, tcgetpgrp): New functions.
3604 Simplify by assuming __fpending.
3605 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
3606 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
3607 Do not assume that __fpending's result fits in int.
3609 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
3611 Remove EMACS_OUTQSIZE+sleep hack.
3612 * dispnew.c (update_frame_1): Remove hack for terminals slower
3613 than 2400 bps, which throttled Emacs by having it sleep.
3614 This code hasn't worked since at least 2007, when the multi-tty stuff
3615 was added, and anyway those old terminals are long dead.
3616 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
3617 without the dispnew.c change, as dispnew.c doesn't include systty.h.
3619 Fix data-loss with --version (Bug#9574).
3620 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
3621 as we can't assume that emacs_strerror is initialized, and strerror
3622 is good enough here.
3623 (main): Invoke atexit earlier, to catch earlier instances of
3624 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
3626 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
3628 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
3629 (keyDown): Remap keypad keys to X11 virtual key codes.
3631 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
3633 Fix data-loss with --batch (Bug#9574).
3634 * emacs.c: Include <close-stream.h>.
3635 (close_output_streams): New function.
3636 (main): Pass it to atexit, so that Emacs closes stdout and stderr
3637 and handles errors appropriately.
3638 (Fkill_emacs): Don't worry about flushing, as close_output_stream
3641 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
3642 The symptom is a diagnostic "GLib-WARNING **: In call to
3643 g_spawn_sync(), exit status of a child process was requested but
3644 SIGCHLD action was set to SIG_IGN and ECHILD was received by
3645 waitpid(), so exit status can't be returned." The diagnostic
3646 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
3647 The real bug is a race condition between Emacs and glib: Emacs
3648 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
3649 so that glib can't find it. Work around the bug by invoking
3650 waitpid only on subprocesses that Emacs itself creates.
3651 * process.c (create_process, record_child_status_change):
3652 Don't use special value -1 in pid field, as the caller now must
3653 know the pid rather than having the callee infer it.
3654 The inference was sometimes incorrect anyway, due to another race.
3655 (create_process): Set new 'alive' member if child is created.
3656 (process_status_retrieved): New function.
3657 (record_child_status_change): Use it.
3658 Accept negative 1st argument, which means to wait for the
3659 processes that Emacs already knows about. Move special-case code
3660 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
3661 processes that have already been waited for, by testing and
3662 clearing new 'alive' member.
3663 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
3664 now does this internally.
3665 (handle_child_signal): Let record_child_status_change do all
3666 the work, since we do not want to reap all exited child processes,
3667 only the child processes that Emacs itself created.
3668 * process.h (Lisp_Process): New boolean member 'alive'.
3670 Omit duplicate definitions no longer needed with gcc -g3.
3671 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
3672 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
3673 Define only as macros. There's no longer any need to also define
3674 these symbols as enums or as constants, since we now assume
3675 gcc -g3 when debugging.
3677 2012-11-03 Eli Zaretskii <eliz@gnu.org>
3679 * lisp.mk: Adjust comments to the fact that term/internal is now
3680 loaded from loadup.el.
3682 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
3683 (msdos_fatal_signal): New function.
3684 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
3687 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
3688 for GCC versions before 4.
3689 (emacs_raise): Define to call msdos_fatal_signal.
3691 * xdisp.c (init_from_display_pos): Fix initialization of the bidi

3707 * buffer.c (cursor_type): Untabify docstring.
3709 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
3711 * frame.h (struct frame): Drop can_have_scroll_bars member

3757 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
3759 Remove pad from struct input_event.
3760 * termhooks.h (struct input_event): Remove padding field.
3762 * keyboard.c (event_to_kboard): Simplify because frame_or_window
3763 member is never cons for a long time. Adjust comment.
3764 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
3765 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
3766 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
3767 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
3769 2012-11-01 Eli Zaretskii <eliz@gnu.org>

3775 Fix crash when using Emacs as commit editor for git (Bug#12697).
3776 * callproc.c (setpgrp): Remove macro, as we now use setpgid
3777 and it is configured in conf_post.h.
3778 (Fcall_process): Don't invoke both setsid and setpgid; the former
3779 is enough, if it exists.
3780 * callproc.c (Fcall_process, child_setup):
3781 * process.c (create_process): Use setpgid.
3782 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
3784 * dispnew.c (init_display): Initialize the foreground group
3785 if we are running a tty display.
3786 * emacs.c (main): Do not worry about setpgrp; init_display does it now.

3798 2012-10-31 Martin Rudalics <rudalics@gmx.at>
3800 * minibuf.c (read_minibuf): Restore current buffer since
3801 choose_minibuf_frame calling Fset_frame_selected_window may
3802 change it (Bug#12766).

3810 * font.c (Ffont_at): If WINDOW is specified and it is not
3811 displaying the current buffer, signal an error.
3813 2012-10-29 Daniel Colascione <dancol@dancol.org>
3815 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
3816 In preparation for fixing bug#12739, move these functions from
3819 * coding.h, coding.c: ... to here, and compile them only when
3820 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
3821 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
3823 2012-10-28 Eli Zaretskii <eliz@gnu.org>
3825 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.

3840 remove last_appdefined_event (Bug#12698).
3842 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
3844 * frame.c (x_set_font): Catch internal error.
3846 2012-10-27 Eli Zaretskii <eliz@gnu.org>
3848 Avoid overflow in w32 implementation of interval timers.
3849 When possible, for ITIMER_PROF count only times the main thread
3851 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
3852 'volatile ULONGLONG' types. All the other data which was
3853 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
3854 (GetThreadTimes_Proc): New typedef.
3855 (w32_get_timer_time): New function, returns a suitable time value
3857 (timer_loop): Enter critical section when accessing ULONGLONG
3858 values of the itimer_data struct, as these accesses are no longer
3859 atomic. Call 'w32_get_timer_time' instead of 'clock'.
3860 Remove unused variable.
3861 (init_timers): Initialize s_pfn_Get_Thread_Times.
3862 (start_timer_thread): Don't assign itimer->caller_thread here.

3869 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
3870 mouse movement events if the menu bar is active. This avoids
3871 producing a busy "hour-glass" cursor by Windows if the mouse
3872 pointer is positioned over a tooltip shown for some menu item.
3874 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
3876 Don't assume process IDs fit in int.
3877 * emacs.c (shut_down_emacs) [!DOS_NT]:
3878 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
3879 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
3880 Use pid_t, not int, to store process IDs, as 'int'
3881 is not wide enough on a few platforms (e.g., AIX and IRIX).
3883 2012-10-23 Kenichi Handa <handa@gnu.org>
3885 The following change is to make face-font-rescale-alist work
3886 correctly for non-ASCII fonts.

3906 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
3908 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>

3911 * frame.c (Fmouse_position, Fmouse_pixel_position):
3912 * xdisp.c (produce_stretch_glyph):
3913 Declare local vars only when they're needed.
3914 This is clearer and avoids a warning on OpenBSD about unused vars.

3916 This is safer, and avoids OpenBSD warnings about unused vars.
3917 * keyboard.c (record_menu_key): Remove unnecessary decl.
3918 (poll_timer): Define only if POLL_FOR_INPUT is defined.
3919 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
3920 as our definition clashes with OpenBSD's.
3921 * xfaces.c (load_face_colors, check_lface_attrs)
3922 (get_lface_attributes_no_remap, get_lface_attributes)
3923 (lface_fully_specified_p, x_supports_face_attributes_p)
3924 (tty_supports_face_attributes_p, face_fontset, realize_face)
3925 (realize_x_face, realize_tty_face):
3926 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
3927 merely Lisp_Object *. This is more informative and avoids
3928 a warning on OpenBSD about accessing beyond an object's size.
3930 2012-10-20 Chong Yidong <cyd@gnu.org>
3932 * lread.c (Fload): Doc fix (Bug#12592).

3958 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
3959 (staticpro): If we run out of staticpro slots, die with an
3960 informative error instead of just calling emacs_abort.
3962 2012-10-18 Martin Rudalics <rudalics@gmx.at>
3964 Fix two flaws reported by Dmitry Antipov.

4215 * keyboard.c (timers_run, swallow_events)
4216 (detect_input_pending_run_timers):
4217 * process.c (wait_reading_process_output):
4218 Use unsigned for counter where wraparound-on-overflow is desired,
4219 since unsigned is guaranteed to have that behavior and signed is not.
4220 (read_char): Use ptrdiff_t for string length.
4221 (get_input_pending): Remove first argument, since it was always
4222 the same pointer-to-int (now pointer-to-boolean) &input_pending,
4223 and behave as if it had that value. Return new value of
4224 input_pending. All callers changed.
4225 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
4226 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's
4228 * keymap.c (push_key_description): Omit last arg, which was always 1.
4229 All callers changed.
4231 * regex.c (immediate_quit) [emacs]: Remove duplicate decl.

4242 initializer for PVEC_NORMAL_VECTOR.
4244 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
4246 Clean out old termopts cruft.
4247 * termopts.h (flow_control, meta_key): Remove unused decls.
4248 * dispnew.c, indent.c, nsterm.m, term.c, xsettings.c, xsmfns.c:
4249 Don't include termopts.h.
4251 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>
4253 * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers.
4255 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
4257 * commands.h (immediate_quit): Remove duplicate decl.
4259 2012-10-09 Jan Djärv <jan.h.d@swipnet.se>
4261 * nsfont.m (Vfonts_in_cache): Remove, not needed as font.c handles

4264 (syms_of_nsfont): Remove initialization of Vfonts_in_cache.
4266 2012-10-09 Eli Zaretskii <eliz@gnu.org>
4268 * w32fns.c (w32_last_error): Change the return value to DWORD, to
4269 match what GetLastError returns. Explain why the function is
4272 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
4273 'is_tooltip_frame', to avoid confusion with its global namesake.
4275 2012-10-08 Daniel Colascione <dancol@dancol.org>
4277 * xdisp.c (start_hourglass): Call w32_note_current_window when
4278 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
4279 build that caused Emacs to display the hourglass cursor forever.
4281 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
4282 which is broken under remote desktop, calculate the number of
4283 colors available for a display based on the display's number of
4284 planes and number of bits per pixel per plane. (bug#10397).
4286 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
4288 * nsfont.m (Vfonts_in_cache): New variable.
4289 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
4290 are used. Add cached fonts to Vfonts_in_cache.
4291 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
4293 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
4295 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
4297 (FONT_H): Define after FRAME_H.
4298 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
4299 Update dependencies.
4301 * w32term.c: Remove leftover declaration of keyboard_codepage.
4303 2012-10-08 Eli Zaretskii <eliz@gnu.org>
4305 * makefile.w32-in (FONT_H): Add $(FRAME_H).
4306 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
4307 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
4308 (GLOBAL_SOURCES): Add cygw32.c.
4309 ($(BLD)/unexw32.$(O)):
4311 ($(BLD)/w32console.$(O)):
4312 ($(BLD)/w32fns.$(O)):
4313 ($(BLD)/w32heap.$(O)):
4314 ($(BLD)/w32menu.$(O)):
4315 ($(BLD)/w32proc.$(O)): Add w32common.h.
4317 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
4319 (x_to_w32_color): Don't modify the argument, modify a copy instead.
4321 2012-10-08 Daniel Colascione <dancol@dancol.org>
4323 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
4324 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
4325 accidental message numbering hole. Change other messages to
4328 * w32select.h (HAVE_W32SELECT): Remove.
4330 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
4331 w32common.h instead of w32heap.h.
4333 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
4334 (get_allocation_unit, get_processor_type, get_w32_major_version)
4335 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
4336 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
4337 (OS_NT, os_subtype, cache_system_info): Move declarations to
4340 * w32heap.c: Include w32common.h.
4341 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
4342 (w32_minor_version, w32_build_number, w32_subtype):
4343 Remove duplicate definitions.
4345 * w32fns.c: Include w32common.h; include w32heap.h only in
4348 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
4349 Use `report_file_error' instead of `error' in order to better
4350 inform users of what went wrong. Increase NTGUI_UNICODE file
4351 dialog box file name length to 32k, the maximum allowed by the NT
4354 * w32common.h: New file.
4355 (ROUND_UP, ROUND_DOWN, get_page_size)
4356 (get_allocation_unit, get_processor_type, get_w32_major_version)
4357 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
4358 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
4359 (OS_NT, os_subtype, cache_system_info): Move here.
4361 * unexw32.c, unexcw.c: Include w32common.h.
4363 * emacs.c (main): Use (defined (WINDOWSNT) || defined
4364 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
4365 to call syms_of_w32select.
4367 * cygw32.h: Remove obsolete EXFUN declarations.
4369 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
4371 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
4372 of w32inevt.o from SOME_MACHINE_OBJECTS.
4374 2012-10-08 Daniel Colascione <dancol@dancol.org>
4376 * image.c: Permanent fix for JPEG compilation issue --- limit
4377 jpeglib `boolean' redefinition to Cygwin builds.
4379 2012-10-08 Eli Zaretskii <eliz@gnu.org>
4381 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
4383 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
4386 2012-10-08 Daniel Colascione <dancol@dancol.org>
4388 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
4389 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
4390 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
4391 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
4392 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
4393 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
4394 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
4395 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
4396 now a supported configuration.
4398 * Makefile.in: consolidate image variables into LIBIMAGE; add
4399 W32_OBJ and W32_LIBS. Compile new files.
4402 (_DebPrint) declare tracing facility for W32 debugging. We need
4403 to unify tracing later.
4405 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
4406 unconditional use of W32 Unicode functions. Cygwin runs only on
4407 100% Unicode operating systems.
4409 * cygw32.c: New file. Define Cygwin-specific facilities.
4410 (Fcygwin_convert_path_to_windows)
4411 (Fcygwin_convert_path_from_windows): New user functions for
4412 accessing Cygwin path-munging routines.
4414 * cygw32.h: New file.
4415 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
4416 UTF-16LE strings temporarily inside non-Lisp-visible string
4419 (w32_strerror): Just what it says on the tin.
4421 * emacs.c: Make the NS fork-then-exec code for daemon-launching
4422 also run for Cygwin; both systems have the same problem with using
4423 GUI facilities in a forked child. Also call syms_of_cygw32,
4424 syms_of_w32select in correct places.
4426 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
4427 needs fork-then-exec for daemon launching.
4429 * font.h: Include frame.h.
4431 * image.c: Use the image library cache machinery only when we're
4432 compiling for native WINDOWSNT; Cygwin can use shared libraries
4433 like any other Unixlike system.
4435 * keyboard.c: Clarify a comment regarding the input loop.
4437 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
4438 functions directly instead of trying to detect at runtime that our
4439 host operating system supports them. We make this change for two
4440 reasons: Cygwin lacks support for the multibyte character
4441 conversion functions used by the legacy menu code, and Cygwin
4442 never needs to rely on non-Unicode APIs.
4444 * unexw32.c (hinst): Declare extern.
4446 * w32.c: Change header order;
4447 (w32_strerror): Move to w32fns.c because we need it for
4448 non-WINDOWSNT builds.
4450 * w32.h: Add #error macro to make sure we don't include w32.h for
4451 Cygwin builds. Remove w32select declarations.
4453 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
4454 w32fns.c. w32console.c is WINDOWSNT-only.
4456 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
4457 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
4459 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
4460 (w32_major_version, w32_minor_version, w32_build_number)
4461 (os_subtype, sound_type): Define here
4462 (w32_defined_color): Make color parameter const for consistency
4463 with other _defined_color functions.
4464 (w32_createwindow): Unconditionally call w32_init_class instead of
4465 doing so only when hprevinst is non-NULL. Plumbing hprevinst
4466 through the code is complex and unnecessary because class
4467 registration is practically free.
4468 (w32_name_of_message): New EMACSDEBUG-only function.
4469 (Fset_message_beep): Move here
4470 (Fx_open_connection): Require that the display name for Windows be
4471 "w32" for consistency, emacsclient disambiguation, and maybe, one
4472 day, multi-window-system support.
4473 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
4474 Cygwin files for W32 GUI facilities, since these clearly don't
4475 expect Cygwin names.
4476 (_DebPrint): Define.
4477 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
4478 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
4479 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
4480 (w32_last_error): Remove.
4482 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
4484 * w32heap.c (syspage_mask): Declare here.
4485 (cache_system_info): Remove.
4487 * w32inevt.c (faked_key): Define globally, not statically.
4488 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
4489 (w32_console_toggle_lock_key): Move to w32fns.c.
4491 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
4493 * w32proc.c (_DebPrint): Move to w32fns.c.
4494 * w32select.c: Include string.h, stdio.h for Cygwin.
4495 * w32select.h: New File.
4497 * w32term.c: Include io.h for non-CYGWIN builds; needed for
4499 (w32_message_fd): New variable. Under Cygwin, holds the file
4500 descriptor the system used to tell us about pending thread
4503 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
4504 that prevented compilation under non-WINDOWSNT systems.
4506 (w32_initialize): Open /dev/windows and assign it to
4507 w32_message_fd. Provide w32 feature.
4509 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
4510 (WM_EMACS_INPUT_READY): add.
4511 (prepend_msg, w32_message_fd): Declare globally.
4514 (keyboard_handle): Use only when WINDOWSNT.
4515 (notify_msg_ready): New function. Posts a message to the main
4516 thread's message queue under CYGWIN, which wakes up the main
4517 thread from select(2) by making the /dev/windows file descriptor
4518 ready. Under WINDOWSNT, it sets an event the same way the old
4521 (post, prepend_msg): Actually call notify_msg_ready instead of
4522 setting the input event directly.
4524 2012-10-07 Eli Zaretskii <eliz@gnu.org>
4526 * ralloc.c (relinquish): If a heap is ready to be relinquished,
4527 but it still has blocs in it, don't return it to the system,
4528 instead of aborting. (Bug#12402)
4530 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
4532 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
4534 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
4535 MAC_OS_X_VERSION_10_6.
4536 (syms_of_nsterm): Remove comment about Panther and above for
4538 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
4539 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
4540 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
4542 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
4543 MAC_OS_X_VERSION_10_4.
4545 * nsmenu.m (fillWithWidgetValue:): Remove code for <
4546 MAC_OS_X_VERSION_10_2.
4548 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
4550 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
4551 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
4553 * nsterm.m (ns_in_resize): Remove (Bug#12479).
4554 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
4555 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
4556 Remove ns_in_resize check.
4557 (ns_clear_frame_area): Remove resize handle code.
4559 * nsfns.m (ns_in_resize): Remove.
4560 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
4561 Remove ns_in_resize check.
4563 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
4565 Improve sys_siglist detection.
4566 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
4567 defined as a macro, as is done in Solaris.
4568 (sys_siglist_entries): New macro.
4569 (save_strsignal): Use it.
4570 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
4571 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
4573 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
4575 * nsfns.m (Fx_create_frame): Call x_default_parameter with
4576 fullscreen/Fullscreen.
4578 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
4579 tobar_height is new.
4581 * nsterm.m (x_make_frame_visible): Check for fullscreen.
4582 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
4583 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
4584 (windowDidResize:): Check for correct window if old style fullscreen.
4585 Capitalize word in comment. Remove incorrect comment.
4586 (initFrameFromEmacs:): tbar_height renamed tibar_height.
4587 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
4588 error in drawing background.
4589 (toggleFullScreen:): Remove comment. Rearrange calls.
4590 Set toolbar values to zero, save old height in tobar_height.
4591 Restore tool bar height when leaving fullscreen.
4592 (canBecomeMainWindow): New function.
4594 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
4596 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
4598 2012-10-05 Eli Zaretskii <eliz@gnu.org>
4600 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
4602 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
4603 that time stamps of directories could also be changed.
4604 Don't request the too broad GENERIC_WRITE, only the more restrictive
4605 FILE_WRITE_ATTRIBUTES access rights.
4607 * fileio.c (Fset_file_times): Special-case ignoring errors for
4608 directories only on MSDOS, not on MS-Windows.
4610 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
4612 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
4614 2012-10-04 Eli Zaretskii <eliz@gnu.org>
4616 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
4617 see whether CreateFile failed.
4619 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
4621 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
4622 to avoid similar races.
4623 * keyboard.c (pending_signals): Now bool, not int.
4625 Port timers to OpenBSD, plus check for timer failures.
4626 OpenBSD problem reported by Han Boetes.
4627 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
4629 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
4630 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
4631 like OpenBSD, which has timer_settime but does not declare it.
4632 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
4633 whether to use itimerspec-related primitives. All uses of
4634 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
4636 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
4638 * profiler.c (handle_profiler_signal): Fix a malloc race
4639 that caused Emacs to hang on Fedora 17 when profiling Lisp.

4662 Now 'static', not 'static inline'.
4664 Count overruns when profiling; change units to ns.
4665 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
4666 Give extra weight to samples after overruns, to attempt to count
4667 the time more accurately.
4668 (setup_cpu_timer): Change sampling interval units from ms to ns, since
4669 the underlying primitives nominally do ns.
4670 (Fprofiler_cpu_start): Document the change. Mention that
4671 the sampling intervals are only approximate.
4673 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
4675 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.

4687 Update dependencies.
4689 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
4691 Fix a malloc race condition involving strsignal.
4692 A signal can arrive in the middle of a malloc, and Emacs's signal
4693 handler can invoke strsignal, which can invoke malloc, which is
4694 not portable. This race condition bug makes Emacs hang on GNU/Linux.
4695 Fix it by altering the signal handler so that it does not invoke
4697 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
4698 * process.c (status_message): Use const pointer, in case strsignal
4699 is #defined to safe_strsignal.
4700 * sysdep.c (sys_siglist, init_signals): Always define and
4701 initialize a substitute sys_siglist if the system does not define
4702 one, even if HAVE_STRSIGNAL.
4703 (safe_strsignal): Rename from strsignal. Always define,
4704 using sys_siglist. Return a const pointer.
4705 * syssignal.h (safe_strsignal): New decl.
4706 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
4708 2012-10-01 Eli Zaretskii <eliz@gnu.org>
4710 * w32proc.c (timer_loop): Fix code that waits for timer
4711 expiration, to avoid high CPU usage.
4713 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
4715 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
4716 (sweep_weak_table): Remove redundant prototypes.
4718 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
4720 * emacs.c: Move the inclusion of TERM_HEADER after including
4721 windows.h on WINDOWSNT. This avoids compilation problems with
4724 2012-10-01 Eli Zaretskii <eliz@gnu.org>
4726 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
4727 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
4728 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
4729 as the previous version used 'void *'.
4731 * ralloc.c (ROUNDUP): Fix last change.
4732 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
4735 * w32proc.c <disable_itimers>: New static flag.
4736 (init_timers): Initialize it to zero, after creating the critical
4737 sections used by the timer threads.
4738 (term_timers): Set to 1 before deleting the critical sections.
4739 (getitimer, setitimer): If disable_itimers is non-zero, return an
4740 error indication without doing anything. Reported by Fabrice
4741 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
4742 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
4744 [!HAVE_SETITIMER]: Behave as the previous version that didn't
4747 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
4748 term_ntproc after all the other bookkeeping, to get timers working
4749 as long as possible.
4751 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
4753 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
4754 Suggested by Juri Linkov in
4755 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
4757 Prefer plain 'static' to 'static inline' (Bug#12541).
4758 With static functions, modern compilers inline pretty well by
4759 themselves; advice from programmers often hurts as much as it helps.
4760 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
4761 this change shrinks the text size of the Emacs executable by 1.1%
4762 without affecting CPU significantly in my benchmark.
4763 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)

4885 * w32.c (init_environment, get_emacs_configuration): Support AMD64
4887 (init_ntproc): Cast arguments of _open_osfhandle to intptr_t, for
4888 compatibility with x64.
4890 * vm-limit.c (lim_data): Now size_t.
4891 (check_memory_limits): Adjust prototypes of real_morecore and
4892 __morecore to receive argument of type ptrdiff_t. Use size_t for

4918 * frame.c (x_report_frame_params): Use EMACS_UINT for the return
4919 value of FRAME_X_WINDOW, to fit a 64-bit pointer on 64-bit Windows
4922 * image.c (x_bitmap_pixmap): Return ptrdiff_t, not int, since

4948 (struct itimer_data): New definition.
4949 (ticks_now, real_itimer, prof_itimer, clocks_min, crit_real)

4978 2012-09-30 Kenichi Handa <handa@gnu.org>
4980 * coding.c (decode_coding_ccl, encode_coding_ccl): Pay attention
4981 to the buffer relocation which may be caused by ccl_driver.

5038 2012-09-30 Eli Zaretskii <eliz@gnu.org>
5040 * profiler.c (Fprofiler_cpu_stop): Use timer_settime only if
5041 HAVE_TIMER_SETTIME is defined.
5043 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
5045 Profiler improvements: more-accurate timers, overflow checks.
5046 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
5047 signal.h, setjmp.h. Include systime.h instead.
5048 (saturated_add): New function.
5049 (record_backtrace, current_sample_interval): Use EMACS_INT, not size_t.

5055 All uses changed to store the new value.
5056 (handle_profiler_signal): Rename from sigprof_handler_1,
5057 for consistency with other handlers. Do not check whether
5058 cpu_log is a hash-table if garbage collecting, since it
5059 doesn't matter in that case.
5060 (deliver_profiler_signal): Rename from sigprof_handler,
5061 for consistency with other handlers.
5062 (setup_cpu_timer): New function, with much of what used to be in
5063 Fprofiler_cpu_start. Check for out-of-range argument.
5064 Prefer timer_settime if available, and prefer
5065 thread cputime clocks, then process cputime clocks, then
5066 monotonic clocks, to the old realtime clock. Use make_timeval
5067 to round more-correctly when falling back to setitimer.
5068 (Fprofiler_cpu_start): Use it.
5069 (Fprofiler_cpu_stop): Prefer timer_settime if available.
5070 Don't assume that passing NULL as the 2nd argument of setitimer
5071 is the same as passing a pointer to all-zero storage.
5072 Ignore SIGPROF afterwards.
5073 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
5074 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
5075 non-fatal signal handlers. Ignore SIGPROF on startup.
5076 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
5077 in profiler.c, since sysdep.c now uses it.
5079 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.

5092 * alloc.c (Fgarbage_collect):
5093 * eval.c (interactive_p, Fsignal, eval_sub, Ffuncall, Fbacktrace)
5094 (Fbacktrace_frame): Adjust accordingly.
5096 2012-09-28 Glenn Morris <rgm@gnu.org>
5098 * eval.c (Frun_hook_with_args, Frun_hook_with_args_until_success)
5099 (Frun_hook_with_args_until_failure): Doc fixes.
5101 2012-09-28 Eli Zaretskii <eliz@gnu.org>
5103 * xdisp.c (syms_of_xdisp) <Qredisplay_internal>: Rename from

5134 * charset.c, charset.h (maybe_unify_char): Now static.
5135 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
5136 Since this stuff is now private to charset.c, there's no need for
5137 a public macro and no need to inline by hand.
5139 2012-09-26 Tomohiro Matsuyama <tomo@cx4a.org>
5140 Stefan Monnier <monnier@iro.umontreal.ca>
5141 Juanma Barranquero <lekktu@gmail.com>

5166 2012-09-25 Juanma Barranquero <lekktu@gmail.com>
5168 * makefile.w32-in ($(BLD)/callproc.$(O)): Update dependencies.
5170 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>
5172 Prefer POSIX timers if available.
5173 They avoid a race if the timer is too close to the current time.
5174 * atimer.c (alarm_timer, alarm_timer_ok) [SIGEV_SIGNAL]: New static vars.
5175 (set_alarm) [SIGEV_SIGNAL]: Use POSIX timers if available.

5183 STRING_CHAR_ADVANCE.
5185 2012-09-25 Juanma Barranquero <lekktu@gmail.com>
5187 Move Vlibrary_cache to emacs.c and reset before dumping.
5189 * lisp.h (reset_image_types): Declare.
5190 [WINDOWSNT] (Vlibrary_cache): Declare.
5192 * image.c (reset_image_types): New function.
5194 * emacs.c [WINDOWSNT] (Vlibrary_cache): Move from w32.c.
5195 (syms_of_emacs) [WINDOWSNT] <Vlibrary_cache>: Initialize and staticpro.
5196 (Fdump_emacs): Reset Vlibrary_cache and image_types.

5201 * w32.h (Vlibrary_cache): Do not declare.
5203 2012-09-25 Eli Zaretskii <eliz@gnu.org>
5205 * w32proc.c (sys_signal): Handle all signals defined by the
5206 MS-Windows runtime, not just SIGCHLD. Actually install the signal
5207 handlers for signals supported by Windows. Don't override
5208 term_ntproc as the handler for SIGABRT.
5209 (sigaction): Rewrite to call sys_signal instead of duplicating its
5211 (sys_kill): Improve commentary.
5213 * w32.c (term_ntproc): Accept (and ignore) one argument, for
5214 consistency with a signature of a signal handler. All callers
5216 (init_ntproc): Accept an argument DUMPING. If dumping, don't
5217 install term_ntproc as a signal handler for SIGABRT, as that
5218 should be done by the dumped Emacs.
5220 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
5222 * w32select.c (term_w32select): Protect against repeated
5223 invocation by setting clipboard_owner to NULL after calling
5226 * emacs.c (shut_down_emacs, main): Adapt the calls to init_ntproc
5227 and term_ntproc to their modified signatures.
5229 * character.c (char_string, string_char): Remove calls to
5230 MAYBE_UNIFY_CHAR. See the discussion starting at
5231 http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00433.html
5234 2012-09-25 Chong Yidong <cyd@gnu.org>
5236 * xdisp.c (mode_line_inverse_video): Delete obsolete variable.
5238 2012-09-24 Stefan Monnier <monnier@iro.umontreal.ca>
5240 * bytecode.c (exec_byte_code): Signal an error instead of aborting,
5241 when encountering an unknown bytecode.
5243 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
5245 image.c, indent.c: Use bool for booleans.
5246 * dispextern.h (struct image_type): Members valid_p, load, init
5247 now return bool, not int. All uses changed.
5248 * image.c: Omit unnecessary static decls.
5249 (x_create_bitmap_mask, x_build_heuristic_mask):
5250 Return void, not int, since callers don't care about the return value.

5279 Use bool for booleans.
5281 2012-09-24 Chong Yidong <cyd@gnu.org>
5283 * chartab.c (Fset_char_table_default): Obsolete function removed.
5285 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5287 Move pid_t related decls out of lisp.h.
5288 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
5289 (interruptible_wait_for_termination):
5290 Move these decls from lisp.h to syswait.h, since they use pid_t.
5291 Needed on FreeBSD; see Herbert J. Skuhra in
5292 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
5293 * callproc.c: Include syswait.h.

5310 * nsmenu.m (ns_update_menubar):
5311 * nsmenu.m, w32menu.c, xmenu.c (set_frame_menubar):
5312 * xfns.c (Fx_show_tip) [USE_GTK]:
5313 Use bool for boolean.
5314 * gtkutil.c (xg_update_frame_menubar):
5315 * xmenu.c (update_frame_menubar):
5316 Return void, not int, since caller ignores return value.

5320 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
5322 * makefile.w32-in (BLOCKINPUT_H): Remove.

5339 2012-09-23 Eli Zaretskii <eliz@gnu.org>
5341 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
5342 fatal_error_backtrace.
5344 * w32proc.c (sys_kill): Undo last change: don't do anything when
5345 invoked to deliver SIGABRT to our own process. This is now
5346 handled by emacs_raise.
5348 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
5350 * w32term.c (w32_read_socket): Remove leftover reference to
5351 interrupt_input_pending.
5353 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5355 Do not use SA_NODEFER.
5356 Problem reported by Dani Moncayo in
5357 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
5359 * sysdep.c (emacs_abort): Do not reset signal handler.
5360 * emacs.c (terminate_due_to_signal): Reset signal handler here.
5361 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
5362 wanted even on POSIXish hosts, and it doesn't work on Windows.
5364 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
5366 * xterm.c (x_term_init): Call fixup_locale before and after calling
5367 gtk_init (Bug#12392).
5369 2012-09-23 Chong Yidong <cyd@gnu.org>
5371 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
5372 Vdynamic_library_alist.
5374 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
5375 (Fgnutls_available_p): Caller changed.
5377 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
5378 (Flibxml_parse_xml_region): Likewise.
5380 * dispextern.h (struct image_type): Remove arg from init function.
5382 * image.c (Finit_image_library, lookup_image_type)
5383 (define_image_type): Remove now-unneeded second arg.
5384 (init_xpm_functions, init_png_functions, init_jpeg_functions)
5385 (init_tiff_functions, init_gif_functions, init_svg_functions):
5386 Arglist and w32_delayed_load calling convention changed.
5387 (gs_type): Remove init_gs_functions; there is no such function.
5388 (valid_image_p, make_image): Fix caller to lookup_image_type.
5390 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5392 Simplify and avoid signal-handling races (Bug#12471).
5394 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
5395 Avoid recursive loop if there's a fatal error in the function itself.
5396 * atimer.c (pending_atimers):
5397 * blockinput.h: Don't include "atimer.h"; no longer needed.
5398 (interrupt_input_pending): Remove. All uses removed.
5399 pending_signals now counts both atimers and ordinary interrupts.
5400 This is less racy than having three separate pending-signal flags.
5401 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
5403 Rename from their upper-case counterparts BLOCK_INPUT,
5404 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
5405 INPUT_BLOCKED_P, and turn into functions. All uses changed.
5406 This makes it easier to access volatile variables more accurately.
5407 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
5408 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
5409 that's more reliable if the code is buggy and sets
5410 interrupt_input_blocked to a negative value. All uses changed.
5411 * atimer.c (deliver_alarm_signal):
5412 Remove. No need to deliver this to the parent; any thread can
5413 handle this signal now. All uses replaced by underlying handler.
5414 * atimer.c (turn_on_atimers):
5415 * dispnew.c (handle_window_change_signal):
5416 * emacs.c (handle_danger_signal):
5417 * keyboard.c (kbd_buffer_get_event):
5418 Don't reestablish signal handler; not needed with sigaction.
5419 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
5421 Rework to avoid unnecessary accesses to volatile variables.
5422 (UNBLOCK_INPUT_TO): Now a function.
5423 (totally_unblock_input, unblock_input): New decls.
5424 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
5425 (init_data): Remove. Necessary stuff now done in init_signal.
5426 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
5427 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
5428 (fatal_error_code): Remove; no longer needed.
5429 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
5430 it doesn't always backtrace. All uses changed. No need to reset
5431 signal to default, since sigaction and/or die does that for us now.
5432 Use emacs_raise (FOO), not kill (getpid (), FOO).
5433 (main): Check more-accurately whether we're dumping.
5434 Move fatal-error setup to sysdep.c
5435 * floatfns.c: Do not include "syssignal.h"; no longer needed.
5436 * gtkutil.c (xg_get_file_name, xg_get_font):
5437 Remove no-longer-needed signal-mask manipulation.
5438 * keyboard.c, process.c (POLL_FOR_INPUT):
5439 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
5440 * keyboard.c (read_avail_input): Remove.
5441 All uses replaced by gobble_input.
5442 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
5443 (kbd_buffer_store_event_hold, gobble_input):
5444 (record_asynch_buffer_change) [USABLE_SIGIO]:
5445 (store_user_signal_events):
5446 No need to mess with signal mask.
5447 (gobble_input): If blocking input and there are terminals, simply
5448 set pending_signals to 1 and return. All hooks changed to not
5449 worry about whether input is blocked.
5450 (process_pending_signals): Clear pending_signals before processing
5451 them, in case a signal comes in while we're processing.
5452 By convention callers now test pending_signals before calling us.
5453 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
5454 New functions, to support changes to blockinput.h.
5455 (handle_input_available_signal): Now extern.
5456 (reinvoke_input_signal): Remove. All uses replaced by
5458 (quit_count): Now volatile, since a signal handler uses it.
5459 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
5460 All callers changed. Block SIGINT only if not already blocked.
5461 Clear sigmask reliably, even if Fsignal returns, which it can.
5462 Omit unnecessary accesses to volatile var.
5463 (quit_throw_to_read_char): No need to restore sigmask.
5464 * keyboard.c (gobble_input, handle_user_signal):
5465 * process.c (wait_reading_process_output):
5466 Call signal-handling code rather than killing ourselves.
5467 * lisp.h: Include <float.h>, for...
5468 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
5469 (pending_signals): Now volatile.
5470 (syms_of_data): Now const if IEEE floating point.
5471 (handle_input_available_signal) [USABLE_SIGIO]:
5472 (terminate_due_to_signal, record_child_status_change): New decls.
5473 * process.c (create_process): Avoid disaster if memory is exhausted
5474 while we're processing a vfork, by tightening the critical section
5476 (send_process_frame, process_sent_to, handle_pipe_signal)
5477 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
5479 (send_process): No need for setjmp/longjmp any more, since the
5480 SIGPIPE stuff is now gone. Instead, report an error if errno
5482 (record_child_status_change): Now extern. PID and W are now args.
5483 Return void, not bool. All callers changed.
5484 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
5485 Remove. All uses removed. This bug should be fixed now in a
5487 (wait_for_termination_1): Use waitpid rather than sigsuspend,
5488 and record the child status change directly. This avoids the
5489 need to futz with the signal mask.
5490 (process_fatal_action): Move here from emacs.c.
5491 (emacs_sigaction_flags): New function, containing
5492 much of what used to be in emacs_sigaction_init.
5493 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
5494 caught by emacs, to make races less likely.
5495 (deliver_process_signal): Rename from handle_on_main_thread.
5497 (BACKTRACE_LIMIT_MAX): Now at top level.
5498 (thread_backtrace_buffer, threadback_backtrace_pointers):
5500 (deliver_thread_signal, deliver_fatal_thread_signal):
5501 New functions, for more-accurate delivery of thread-specific signals.
5502 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
5503 (deliver_arith_signal): Handle in this thread, not
5504 in the main thread, since it's triggered by this thread.
5505 (maybe_fatal_sig): New function.
5506 (init_signals): New arg DUMPING so that we can be more accurate
5507 about whether we're dumping. Caller changed.
5508 Treat thread-specific signals differently from process-general signals.
5509 Block all signals while handling fatal error; that's safer.
5510 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
5512 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
5513 Ignore SIGPIPE unless batch.
5514 (emacs_backtrace): Output backtrace for the appropriate thread,
5515 which is not necessarily the main thread.
5516 * syssignal.h: Include <stdbool.h>.
5517 (emacs_raise): New macro.
5518 * xterm.c (x_connection_signal): Remove; no longer needed
5519 now that we use sigaction.
5520 (x_connection_closed): No need to mess with sigmask now.
5521 (x_initialize): No need to reset SIGPIPE handler here, since
5522 init_signals does this for us now.
5524 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
5526 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
5527 background rect may be larger (Bug#12245).
5529 2012-09-23 Chong Yidong <cyd@gnu.org>
5531 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
5533 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
5535 * .gdbinit: Just stop at fatal_error_backtrace.
5536 See Stefan Monnier's request in
5537 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
5538 Remove no-longer-used query of system type.
5540 2012-09-22 Chong Yidong <cyd@gnu.org>
5542 * search.c (Freplace_match): Doc fix (Bug#12325).
5544 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
5546 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
5547 (Fline_end_position): Doc fix.
5549 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
5551 2012-09-22 Chong Yidong <cyd@gnu.org>
5553 * dispextern.h (struct image_type): Add new slot, storing a type
5554 initialization function.
5556 * image.c (define_image_type): Call the image initializer function
5557 if it is defined. Arguments and return value changed.
5558 (valid_image_p, make_image): Callers changed.
5559 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
5560 (gif_type, imagemagick_type, svg_type, gs_type):
5561 Add initialization functions.
5562 (Finit_image_library): Call lookup_image_type.
5563 (CHECK_LIB_AVAILABLE): Macro deleted.
5564 (lookup_image_type): Call define_image_type here, rather than via
5565 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
5566 (syms_of_image): Move define_image_type calls for xbm_type and
5567 pbm_type to lookup_image_type.
5569 2012-09-22 Eli Zaretskii <eliz@gnu.org>
5571 * keyboard.c (timer_check_2): Move calculation of 'timers' and
5572 'idle_timers' from here ...
5573 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
5574 lists, to avoid infloops when the timer does something stupid,
5575 like reinvoke itself with the same or smaller time-out.
5578 2012-09-22 Martin Rudalics <rudalics@gmx.at>
5580 * window.c (Fsplit_window_internal): Handle only Qt value of
5581 Vwindow_combination_limit separately.
5582 (Qtemp_buffer_resize): New symbol.
5583 (Vwindow_combination_limit): New default value.
5586 2012-09-22 Eli Zaretskii <eliz@gnu.org>
5588 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
5589 the new overlay string. (Bug#10159)
5591 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
5593 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
5594 or that fprintf is async-signal-safe. POSIX doesn't require
5597 2012-09-22 Chong Yidong <cyd@gnu.org>
5599 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
5602 2012-09-22 Kenichi Handa <handa@gnu.org>
5604 * composite.c (composition_reseat_it): Handle the case that a
5605 grapheme cluster is not covered by a single font (Bug#12352).
5607 2012-09-21 Chong Yidong <cyd@gnu.org>
5609 * image.c (define_image_type): Avoid adding duplicate types to
5610 image_types (Bug#12463). Suggested by Jörg Walter.
5612 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5614 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
5615 (print_load_command_name): Add case LC_DATA_IN_CODE.
5616 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
5618 2012-09-21 Glenn Morris <rgm@gnu.org>
5620 * eval.c (Frun_hook_with_args_until_success)
5621 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
5623 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
5625 * fileio.c (Ffile_selinux_context): Only call freecon when
5626 lgetfilecon succeeded.
5627 (Fset_file_selinux_context): Likewise. (Bug#12444)
5629 2012-09-21 Eli Zaretskii <eliz@gnu.org>
5631 * xdisp.c (try_window_reusing_current_matrix): Under bidi
5632 reordering, locate the cursor by calling set_cursor_from_row; if
5633 that fails, clear the desired glyph matrix before returning a
5634 failure indication to the caller. Fixes leaving garbled display
5635 when fast scrolling with a down-key. (Bug#12403)
5636 (compute_stop_pos_backwards): Fix a typo that caused crashes while
5637 scrolling through multibyte text.
5639 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
5641 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
5642 calling mark_vectorlike since that's the one that marks the window.
5643 (mark_discard_killed_buffers): Mark the final cdr.
5644 * window.h (struct window): Move prev/next_buffers to the
5645 non-standard fields.
5646 * window.c (make_window): Initialize prev/next_buffers manually.
5648 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
5650 Omit unused arg EXPECTED from socket hooks.
5651 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
5652 * nsterm.m (ns_term_init):
5653 * termhooks.h (struct terminal.read_socket_hook):
5654 * w32inevt.c (w32_console_read_socket):
5655 * w32term.c (w32_read_socket):
5656 * xterm.c (XTread_socket):
5657 Omit unused arg EXPECTED. All callers changed.
5658 (store_user_signal_events): Return void, not int, since callers no
5659 longer care about the return value. All uses changed.
5661 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
5663 * w32gui.h (XParseGeometry): Do not declare.
5665 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
5667 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
5668 Ignore 'expected'. See Eli Zaretskii in
5669 <http://bugs.gnu.org/12471#8> (last line).
5671 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
5672 (XParseGeometry): Now static. Substitute extremal values for
5673 values that are out of range.
5675 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
5677 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
5679 * nsfns.m (XParseGeometry): Remove.
5680 (Fx_create_frame): Call x_set_offset to correctly interpret
5681 top_pos in geometry.
5683 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
5684 (Fx_parse_geometry): If there is a space in string, call
5685 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
5687 2012-09-17 Eli Zaretskii <eliz@gnu.org>
5689 * search.c (scan_buffer): Use character positions in calls to
5690 region_cache_forward and region_cache_backward, not byte
5691 positions. (Bug#12196)
5693 * w32term.c (w32_read_socket): Set pending_signals to 1, like
5694 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
5696 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
5697 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
5698 emacs_blocked_malloc, now deleted.
5700 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
5702 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
5703 The workaround was for improving performance on Solaris 2.4, but
5704 is getting in the way now. Emacs will still work if someone is
5705 still running Solaris 2.4 in a museum somewhere; Sun dropped
5706 support for Solaris 2.4 in 2003.
5707 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
5708 * process.c (create_process) [HAVE_WORKING_VFORK]:
5709 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
5710 since Emacs no longer uses vfork on that platform.
5712 2012-09-17 Glenn Morris <rgm@gnu.org>
5714 * emacs.c: Use COPYRIGHT.
5716 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
5718 Remove configure's --without-sync-input option (Bug#12450).
5719 When auditing signal-handling in preparation for cleaning it up,
5720 I found that SYNC_INPUT has race conditions and would be a real
5721 pain to fix. Since it's an undocumented and deprecated
5722 configure-time option, now seems like a good time to remove it.
5723 Also see <http://bugs.gnu.org/11080#16>.
5724 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
5725 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
5726 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
5727 (malloc_hysteresis):
5728 (check_depth) [XMALLOC_OVERRUN_CHECK]:
5729 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
5730 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
5731 (dont_register_blocks, bytes_used_when_reconsidered)
5732 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
5733 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
5734 [!SYSTEM_MALLOC && !SYNC_INPUT]:
5735 Remove. All uses removed.
5736 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
5737 implementation, one that depends on whether the new macro
5738 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
5740 * atimer.c (run_timers, handle_alarm_signal):
5741 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
5742 (handle_async_input, process_pending_signals)
5743 (handle_input_available_signal, init_keyboard):
5744 * nsterm.m (ns_read_socket):
5745 * process.c (wait_reading_process_output):
5746 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
5747 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
5749 * xterm.c (XTread_socket):
5751 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
5752 * eval.c (handling_signal): Remove. All uses removed.
5753 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
5754 All uses replaced with the SYNC_INPUT version.
5755 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
5757 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5760 * font.c (Ffont_shape_gstring): Remove unused local.
5762 2012-09-16 Glenn Morris <rgm@gnu.org>
5764 * Makefile.in (clean): No longer run nextstep's clean.
5766 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
5768 (ns-app): Move here from ns.mk, and simplify.
5769 (clean): Simplify nextstep entry.
5770 * ns.mk: Remove file.
5772 2012-09-17 Kenichi Handa <handa@gnu.org>
5774 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
5775 not covert the last few charactes.
5777 2012-09-16 Kenichi Handa <handa@gnu.org>
5779 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
5780 here, but just check the validity of glyphs in the glyph-string.
5782 2012-09-16 Martin Rudalics <rudalics@gmx.at>
5784 * window.c (Fwindow_parameter, Fset_window_parameter):
5785 Accept any window as argument (Bug#12452).
5787 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
5789 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
5790 to ns_term_init to avoid memory leak.
5792 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
5793 explicit retain/release.
5794 (ns_term_init): Only allow one display. Initialize outerpool and
5797 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
5799 Port _setjmp fix to POSIXish hosts as well as Microsoft.
5800 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
5801 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
5802 the Microsoft problem in a different way, by altering ../nt/config.nt.
5804 2012-09-15 Eli Zaretskii <eliz@gnu.org>
5819 * w16select.c: Remove inclusion of setjmp.h, as it is now included
5820 by lisp.h. This completes removal of setjmp.h inclusion
5821 erroneously announced in the previous commit. (Bug#12446)
5823 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
5826 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
5827 not defined as a macro. The latter happens on MS-Windows.
5830 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
5832 Port better to POSIX hosts lacking _setjmp (Bug#12446).
5833 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
5834 Some instances of '#include <setjmp.h>' removed, if the
5835 only reason for the instance was because "lisp.h" was included.
5836 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
5837 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
5838 and _longjmp with the new symbols. Emacs already uses _setjmp if
5839 available, so this change affects only POSIXish hosts that have
5840 sigsetjmp but not _setjmp, such as some versions of Solaris and
5841 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
5842 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
5843 (png_load_body) [HAVE_PNG]:
5844 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
5845 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
5846 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
5847 since PNG requires jmp_buf. This is the only exception to the
5848 general rule that we now use sys_setjmp and sys_longjmp.
5849 This exception is OK since this code does not change the signal
5850 mask or longjmp out of a signal handler.
5852 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
5854 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
5855 Include "syssignal.h", for 'main_thread'.
5857 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
5859 Avoid out-of-range marker position (Bug#12426).
5860 * insdel.c (replace_range, replace_range_2):
5861 Adjust markers before overlays, as suggested by comments.
5862 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
5863 Remove redundant check before calling offset_intervals.
5865 2012-09-14 Martin Rudalics <rudalics@gmx.at>
5867 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
5868 current buffer (Bug#12387).
5870 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
5872 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
5874 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
5876 Use a more backwards-compatible timer format (Bug#12430).
5877 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
5878 vector element, not from the 4th, since PSECS is now at the end.
5879 (Fcurrent_idle_time): Doc fix.
5881 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
5883 Function to mark objects and remove killed buffers at once.
5884 * alloc.c (discard_killed_buffers): Rename to ...
5885 (mark_discard_killed buffers) ... new name. Add marking
5886 of remaining objects. Fix comment. Adjust users.
5887 (mark_object): Do not touch frame buffer lists here.
5888 * frame.c (delete_frame): Reset frame buffer lists here.
5890 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
5892 Better workaround for GNOME bug when --enable-gcc-warnings.
5893 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
5894 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
5895 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
5897 Simplify SIGIO usage (Bug#12408).
5898 The code that dealt with SIGIO was crufty and confusing, e.g., it
5899 played tricks like "#undef SIGIO" but these tricks were not used
5900 consistently. Simplify mostly by not #undeffing standard symbols,
5901 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
5902 or not as we please) rather than "defined SIGIO" (standard symbol
5903 that we probably shouldn't #undef).
5904 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
5905 Modules that need it can include it.
5906 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
5907 * dispextern.h (ignore_sigio): New decl.
5908 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
5909 unconditionally, since it's now a no-op if !USABLE_SIGIO.
5910 * emacs.c (shut_down_emacs):
5911 * keyboard.c (kbd_buffer_store_event_hold):
5912 Use ignore_sigio rather than invoking 'signal' directly.
5913 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
5915 (FIONREAD, SIGIO): Do not #undef.
5916 (tty_read_avail_input): Use #error rather than a syntax error.
5917 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
5918 for I_PIPE, used by SETUP_SLAVE_PTY.
5919 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
5920 * sysdep.c (croak): Remove; no longer needed. This bit of
5921 temporary code, with Fred N. Fish's comment that it's temporary,
5922 has been in Emacs since at least 1992!
5923 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
5924 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
5925 * syssignal.h (croak): Remove decl.
5926 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
5927 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
5928 now that we're termios-only.
5929 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
5930 * term.c (dissociate_if_controlling_tty): Use #error rather than
5933 Work around GCC and GNOME bugs when --enable-gcc-warnings.
5934 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
5935 to work around GNOME bug 683906.
5936 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
5937 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
5938 This works around GCC bug 54561.
5940 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
5942 More fixes for 'volatile' and setjmp/longjmp.
5943 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
5944 * image.c (struct png_load_context) [HAVE_PNG]: New type.
5945 (png_load_body) [HAVE_PNG]:
5946 (jpeg_load_body) [HAVE_JPEG]:
5947 New function, with most of the old parent function's body.
5948 (png_load) [HAVE_PNG]:
5949 (jpeg_load) [HAVE_JPEG]:
5950 Invoke the new function, to avoid longjmp munging our locals.
5951 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
5952 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
5953 longjmp is passed 2, as the C standard doesn't guarantee this.
5954 Instead, store the failure code into mgr->failure_code.
5956 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5958 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
5959 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
5960 (syms_of_keyboard): Remove support for unread-command-char.
5962 2012-09-12 Eli Zaretskii <eliz@gnu.org>
5964 * w32proc.c (sys_kill): If PID is our process ID and the signal is
5965 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
5966 violation. (Bug#12426)
5968 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
5970 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
5972 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5974 * eval.c: Add `inhibit-debugger'.
5975 (Qinhibit_debugger): New symbol.
5976 (call_debugger): Bind it instead of Qdebug_on_error.
5977 (maybe_call_debugger): Test Vinhibit_debugger.
5978 (syms_of_eval): Define inhibit-debugger.
5979 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
5980 (syms_of_xdisp): Remove inhibit-debug-on-message.
5982 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5984 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
5985 If a nonvolatile local variable is written before a _longjmp to
5986 the frame containing the variable, and is read after the _longjmp,
5987 the value read is indeterminate. Some local variables of type
5988 'struct handler' and 'struct catchtag' are used in this way, so
5989 mark each of their slots as volatile if the slot can be set before
5990 _longjmp and read afterwards.
5991 * lisp.h (struct handler): var and chosen_clause are now volatile.
5992 (struct catchtag): val, next, and pdlcount are now volatile.
5994 * bidi.c (bidi_push_it, bidi_pop_it):
5995 * fns.c (copy_hash_table):
5996 * image.c (define_image_type):
5997 * keyboard.c (kbd_buffer_store_event_hold):
5998 * process.c (Fprocess_send_eof):
5999 * xfaces.c (x_create_gc) [HAVE_NS]:
6000 * xgselect.c (xg_select):
6001 Prefer assignment to memcpy when either will do.
6003 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
6004 Use pointer-to-a-pointer to simplify and avoid a NILP check each
6005 time an item is removed. No need to mark this function 'inline';
6006 the compiler knows better than we do.
6008 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
6010 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
6011 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
6012 to change_frame_size (Bug#12388).
6013 (windowDidResize:): Pass YES to updateFrameSize.
6015 * nsterm.h: Add delay parameter to updateFrameSize.
6017 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
6019 Discard killed buffers from deleted window and frame objects.
6020 This reduces an amount of references to killed buffers and
6021 helps GC to reclaim them faster.
6022 * alloc.c (discard_killed_buffers): New function.
6023 (mark_object): Use it for deleted windows and frames.
6024 (mark_object): If symbol's value is set up for a killed buffer
6025 or deleted frame, restore its global binding.
6026 * data.c (swap_in_global_binding): Add GC notice.
6027 (swap_in_symval_forwarding): Use convenient set_blv_where.
6028 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
6029 * window.h: ... to here.
6031 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
6033 Convenient macro to check whether the buffer is live.
6034 * buffer.h (BUFFER_LIVE_P): New macro.
6035 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
6036 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
6038 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6040 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
6041 composition cases (Bug#12364).
6043 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
6044 overhang of succeeding glyphs overlapping box cursor.
6046 * w32term.c (x_draw_glyph_string): Likewise.
6048 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
6050 Simplify, document, and port floating-point (Bug#12381).
6051 The porting part of this patch fixes bugs on non-IEEE platforms
6052 with frexp, ldexp, logb.
6053 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
6055 * floatfns.c: Simplify discussion of functions that Emacs doesn't
6056 support, by removing commented-out code and briefly listing the
6057 C89 functions excluded. The commented-out stuff was confusing
6058 maintenance, e.g., we thought we needed cbrt but it was commented out.
6059 (logb): Remove decl; no longer needed.
6060 (isfinite): New macro, if not already supplied.
6061 (isnan): Don't replace any existing macro.
6062 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
6063 are present on all C89 platforms.
6064 (Ffrexp): Do not special-case zero, as frexp does the right thing
6066 (Flogb): Do not use logb, as it doesn't have the desired meaning
6067 on hosts that use non-base-2 floating point. Instead, stick with
6068 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
6069 frexp, to avoid getting an unspecified result.
6071 * xdisp.c (Qinhibit_debug_on_message): Now static.
6073 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
6075 * nsterm.m (ns_update_begin): Set clip path to whole view by using
6076 NSBezierPath (Bug#12131).
6078 2012-09-10 Chong Yidong <cyd@gnu.org>
6080 * fns.c (Fdelq, Fdelete): Doc fix.
6082 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
6084 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
6085 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
6087 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
6089 * lisp.h (make_lisp_ptr): New macro to replace XSET.
6090 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
6093 2012-09-09 Eli Zaretskii <eliz@gnu.org>
6095 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
6096 left fringe if the window has a left margin. This avoids leaving
6097 traces of the cursor because its leftmost pixel is not drawn over.
6099 * dispnew.c (update_window_line): When the left margin area of a
6100 screen line is updated, set the redraw_fringe_bitmaps_p flag of
6101 that screen line. (Bug#12277)
6103 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
6105 Assume C89 or later for math functions (Bug#12381).
6106 This simplifies the code, and makes it a bit smaller and faster,
6107 and (most important) makes it easier to clean up signal handling
6108 since we can stop worring about floating-point exceptions in
6109 library code. That was a problem before C89, but the problem
6110 went away many years ago on all practical Emacs targets.
6111 * data.c, image.c, lread.c, print.c:
6112 Don't include <math.h>; no longer needed.
6113 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
6114 might be autoconfigured, as that never happens.
6116 * doprnt.c (DBL_MAX_10_EXP):
6117 * print.c (DBL_DIG):
6118 Remove. C89 or later always defines these.
6119 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
6120 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
6121 (arith_error, domain_error, domain_error2):
6122 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
6123 no longer needed -- we simply return what C returns. All uses removed.
6124 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
6126 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
6127 Remove. All uses expanded, as these macros are no longer used
6128 more than once and are now more trouble than they're worth.
6129 (Ftan): Use tan, not sin / cos.
6130 (Flogb): Assume C89 frexp.
6131 (fmod_float): Assume C89 fmod.
6132 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
6133 (init_floatfns): Remove. All uses removed.
6135 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6137 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
6138 compositeToPoint for OSX < 10.6 (Bug#12390).
6140 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
6142 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
6143 This produces more-accurate results.
6145 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6147 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
6148 changes (Bug#12088).
6150 2012-09-08 Chong Yidong <cyd@gnu.org>
6152 * syntax.c (Fstring_to_syntax): Doc fix.
6154 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6156 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
6157 in the internal border.
6158 (x_set_window_size): Remove static variables and their usage.
6159 (ns_redraw_scroll_bars): Fix NSTRACE arg.
6160 (ns_after_update_window_line, ns_draw_fringe_bitmap):
6161 Remove fringe/internal border adjustment (Bug#11052).
6162 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
6163 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
6164 (ns_fix_rect_ibw): Remove.
6165 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
6166 (ns_dumpglyphs_box_or_relief): Ditto.
6167 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
6169 (ns_dumpglyphs_image): Ditto.
6170 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
6172 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
6173 their usage. Add fringe_extended_p and its use as in other terms.
6174 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
6175 scroll bar was removed.
6176 (updateFrameSize): New function.
6177 (windowDidResize): Move code to updateFrameSize and call it.
6179 * nsterm.h (EmacsView): Add updateFrameSize.
6181 2012-09-07 Chong Yidong <cyd@gnu.org>
6183 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
6185 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
6187 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
6189 More signal-handler cleanup (Bug#12327).
6190 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
6191 Problem introduced when merging patches. Noted by Eli Zaretskii in
6192 <http://bugs.gnu.org/12327#67>.
6193 * floatfns.c: Comment fix.
6194 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
6195 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
6196 and anyway the declaration is harmless even if SIGDANGER is not defined.
6197 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
6198 defined BROKEN_FIONREAD). systty.h formerly did this, but other
6199 source files not surprisingly expected syssignal.h to define, or
6200 not define, SIGIO, and it's cleaner to do it that way, for consistency.
6201 Include <sys/ioctl.h>, for FIONREAD.
6202 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
6203 This eliminates a problem whereby other files mysteriously had
6204 to include "syssignal.h" before including "systty.h" if they
6205 wanted to use "#ifdef SIGIO".
6207 2012-09-07 Eli Zaretskii <eliz@gnu.org>
6209 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
6211 * w32.c (sigemptyset): Empty the set.
6212 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
6214 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
6216 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
6218 * alloc.c (mark_buffer): Revert unsafe marking optimization.
6219 (mark_object): Likewise for frame objects.
6221 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
6223 * syssignal.h (handle_on_main_thread): Always declare,
6224 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
6225 This ports to platforms without HAVE_PTHREAD.
6227 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
6229 Signal-handler cleanup (Bug#12327).
6230 Emacs's signal handlers were written in the old 4.2BSD style with
6231 sigblock and sigmask and so forth, and this led to some
6232 inefficiencies and confusion. Rewrite these to use
6233 pthread_sigmask etc. without copying signal sets around. Also,
6234 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
6235 'signal', and instead use functions that do not attempt to take
6236 over the system name space. This patch causes Emacs's text
6237 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
6238 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
6239 Do not include <signal.h> or "syssignal.h", as these
6240 modules do not use signals.
6241 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
6242 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
6243 Do not include <signal.h>, as "syssignal.h" does that for us now.
6244 * atimer.c (sigmask_atimers): New function.
6245 (block_atimers, unblock_atimers): New functions,
6246 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
6248 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
6249 no longer needed here.
6250 * emacs.c (main): Inspect existing signal handler with sigaction,
6251 so that there's no need to block and unblock SIGHUP.
6252 * sysdep.c (struct save_signal): New member 'action', replacing
6253 old member 'handler'.
6254 (save_signal_handlers, restore_signal_handlers):
6255 Use sigaction instead of 'signal' to save and restore.
6256 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
6257 New function. All users of 'signal' modified to use set_sighandler
6258 if they're writeonly, and to use sys_signal if they're read+write.
6259 (emacs_sigaction_init, forwarded_signal): New functions.
6260 (sys_signal): Remove. All uses replaced by calls to sigaction
6261 and emacs_sigaction_init, or by direct calls to 'signal'.
6262 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
6263 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
6264 all uses replaced by pthread_sigmask etc. calls.
6265 * syssignal.h: Include <signal.h>.
6266 (emacs_sigaction_init, forwarded_signal): New decls.
6267 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
6268 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
6269 (sigmask, sys_sigmask): Remove; no longer needed.
6270 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
6271 (sigblock, sigunblock, sigfree):
6272 (sigsetmask) [!defined sigsetmask]:
6273 Remove. All uses replaced by pthread_sigmask.
6274 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
6275 no longer need to be replaced, and its typical old uses
6276 are now done via emacs_sigaction_init and sigaction.
6277 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
6278 (sys_sigdel): Remove; unused.
6279 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
6281 2012-09-06 Eli Zaretskii <eliz@gnu.org>
6283 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
6284 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
6286 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
6288 Explicitly mark buffer_defaults and buffer_local_symbols.
6289 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
6290 mark_local_symbols here.
6291 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
6292 since special buffers aren't marked here any more.
6293 (allocate_buffer): Chain new buffer with all_buffers here...
6294 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
6296 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
6297 (syms_of_buffer): Remove staticpro of the above.
6298 (init_buffer_once): Set names for buffer_defaults and
6299 buffer_local_symbols.
6301 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
6303 Use bool for booleans in font-related modules.
6304 * font.c (font_intern_prop, font_style_to_value)
6305 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
6306 (generate_otf_features, font_check_otf_features, font_check_otf)
6307 (font_match_p, font_list_entities, font_at):
6308 * fontset.c (fontset_id_valid_p, reorder_font_vector
6309 (fontset_find_font, Fset_fontset_font)
6310 (face_suitable_for_char_p) [0]:
6311 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
6312 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
6313 (m17n_flt_initialized, ftfont_shape_by_flt):
6314 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
6315 * nsfont.m (nsfont_draw):
6316 * w32font.c (w32font_draw):
6317 * w32term.c (x_draw_glyphless_glyph_string_foreground):
6318 Use bool for booleans.
6319 * font.h: Adjust to above API changes.
6320 (struct font, struct font_driver, struct font_driver_list):
6321 Use bool for booleans.
6322 (struct font): Remove useless member encoding_type.
6324 * fontset.c, xftfont.c: Omit unnecessary static decls.
6326 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
6328 * alloc.c (mark_object): Revert window marking code
6329 since it's unsafe for the Fset_window_configuration.
6331 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
6333 Fix race conditions with signal handlers and errno (Bug#12327).
6334 Be more systematic about preserving errno whenever a signal
6335 handler returns, even if it's not in the main thread. Do this by
6336 renaming signal handlers to distinguish between signal delivery
6337 and signal handling. All uses changed.
6338 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
6339 * data.c (deliver_arith_signal): Rename from arith_error.
6340 * dispnew.c (deliver_window_change_signal): Rename from
6341 window_change_signal.
6342 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
6343 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
6344 * keyboard.c (deliver_input_available_signal): Rename from
6345 input_available_signal.
6346 (deliver_user_signal): Rename from handle_user_signal.
6347 (deliver_interrupt_signal): Rename from interrupt_signal.
6348 * process.c (deliver_pipe_signal): Rename from send_process_trap.
6349 (deliver_child_signal): Rename from sigchld_handler.
6350 * atimer.c (handle_alarm_signal):
6351 * data.c (handle_arith_signal):
6352 * dispnew.c (handle_window_change_signal):
6353 * emacs.c (handle_fatal_signal, handle_danger_signal):
6354 * keyboard.c (handle_input_available_signal):
6355 * keyboard.c (handle_user_signal, handle_interrupt_signal):
6356 * process.c (handle_pipe_signal, handle_child_signal):
6357 New functions, with the actual signal-handling code taken from the
6358 original respective signal handlers, sans the sporadic attempts to
6359 preserve errno, since that's now done by handle_on_main_thread.
6360 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
6361 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
6362 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6364 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6365 Move initialization of main_thread to sysdep.c's init_signals.
6366 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
6367 our usage, and simplifies the mainline code.
6368 (record_child_status_change): New static function, as a helper
6369 for handle_child_signal, and with most of the old child handler's
6371 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
6372 (handle_child_signal): Use the above.
6373 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6374 Moved here from emacs.c.
6375 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
6376 code moved here from emacs.c's main function.
6377 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
6378 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
6379 This lets callers save and restore errno properly.
6381 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6383 Remove redundant or unused things here and there.
6384 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
6385 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
6386 * editfns.c (Fcompare_buffer_substrings): Likewise.
6387 * frame.h (struct terminal, struct font_driver_list):
6388 Remove redundant declarations.
6389 * window.h (Qleft, Qright): Likewise.
6391 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6393 Do not mark objects from deleted buffers, windows and frames.
6394 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
6395 (mark_object): Likewise for windows and frames.
6397 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6399 * alloc.c (valid_lisp_object_p): Treat killed buffers,
6400 buffer_defaults and buffer_local_symbols as valid objects.
6401 Return special value to denote them.
6403 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
6405 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
6406 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
6407 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
6408 (file_name_absolute_p, Fsubstitute_in_file_name):
6409 (check_executable, check_writable, Ffile_accessible_directory_p)
6410 (Fset_file_selinux_context, Fdefault_file_modes)
6411 (Finsert_file_contents, choose_write_coding_system)

6414 * filelock.c (boot_time_initialized, get_boot_time)
6415 (get_boot_time_1, lock_file_1, within_one_second):
6416 * floatfns.c (in_float):
6417 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
6418 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
6419 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
6420 * lisp.h (struct Lisp_Hash_Table.cmpfn):
6421 * window.c (compare_window_configurations):
6422 Use bool for booleans.
6423 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
6424 (Fdefault_file_modes): Now mode_t, not int, for modes.
6425 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
6426 (internal_delete_file): Now returns void, not a (boolean) int,
6427 since nobody was looking at the return value.
6428 * lisp.h, window.h: Adjust to above API changes.
6430 * xdisp.c (set_message): Simplify and reindent last change.
6432 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
6434 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
6436 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
6438 * eval.c (call_debugger): Make the function non-static so that we
6439 can call it from set_message.
6441 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
6442 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
6444 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6446 Give more-useful info on a fatal error (Bug#12328).
6447 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
6448 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
6449 of doing the work ourselves.
6450 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
6451 do most of the work.
6452 (fatal_error_backtrace): New function, taken from the guts
6453 of the old fatal_error_signal, but with a new option to output
6455 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
6456 info about the signal than just its number.
6457 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
6458 * sysdep.c: Include <execinfo.h>
6459 (emacs_backtrace): New function, taken partly from the previous
6460 code of the 'die' function.
6461 (emacs_abort): Call fatal_error_backtrace rather than abort.
6463 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
6465 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
6466 eager (load-time) macro-expansion.
6467 * lisp.mk (lisp): Add macroexp.
6469 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6471 Simplify redefinition of 'abort' (Bug#12316).
6472 Do not try to redefine the 'abort' function. Instead, redo
6473 the code so that it calls 'emacs_abort' rather than 'abort'.
6474 This removes the need for the NO_ABORT configure-time macro
6475 and makes it easier to change the abort code to do a backtrace.
6476 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
6477 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
6478 Remove; sysdep.c's emacs_abort now takes its place.
6479 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
6480 'abort' changed to use 'emacs_abort'.
6481 * msdos.c (dos_abort) [defined abort]: Remove; not used.
6482 (abort) [!defined abort]: Rename to ...
6483 (emacs_abort): ... new name.
6484 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
6485 the place of the old 'abort' in emacs.c.
6486 * w32.c, w32fns.c (abort): Do not #undef.
6487 * w32.c (emacs_abort): Rename from w32_abort.
6489 2012-09-04 Eli Zaretskii <eliz@gnu.org>
6491 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
6492 offsets[j].dv, since the y axis of the screen coordinates points
6493 down, while the y axis of the font definition coordinates points
6494 up. This fixes display of Arabic diacritics such as KASRA and
6495 KASRATAN. (Bug#11860)
6497 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6499 Be more systematic about _setjmp vs setjmp.
6500 * alloc.c (test_setjmp, mark_stack):
6501 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
6502 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
6503 (png_load, my_error_exit, jpeg_load):
6504 * process.c (send_process_trap, send_process):
6505 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
6506 The underscored versions are up to 30x faster on some hosts.
6507 Formerly, the code used setjmp+longjmp sometimes and
6508 _setjmp+_longjmp at other times, with no particular reason to
6509 prefer setjmp+longjmp.
6511 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
6513 Fix minor problem found by static checking.
6514 * buffer.c (Fdelete_all_overlays): Return nil.
6516 2012-09-03 Martin Rudalics <rudalics@gmx.at>
6518 * buffer.c (Fdelete_all_overlays): New function.
6520 2012-09-03 Chong Yidong <cyd@gnu.org>
6522 * gtkutil.c: Add extern decl for Qxft.
6524 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>

6538 All callers changed.
6539 * eval.c (interactive_p): Omit always-true boolean argument
6540 EXCLUDE_SUBRS_P. All callers changed.
6541 * dispextern.h, lisp.h: Reflect above API changes.
6542 * firstfile.c (dummy): Use the address of 'main', whose signature
6543 won't change, instead of the address of 'initialize', whose
6544 signature just changed from int to bool.
6545 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
6546 * msdos.c (fatal_error_in_progress): ... from here.
6547 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
6549 (redisplay_internal, unwind_redisplay): Simply clear
6550 REDISPLAYING_P when unwinding, instead of saving its previous,
6551 always-false value and then restoring it.
6553 Clean up some extern decls.
6554 Mostly, this hoists extern decls out of .c files and into .h files.
6555 That way, we're more likely to catch errors if the interfaces change.
6556 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
6557 declare xg_mark_data.
6558 * dispextern.h (x_frame_parm_handlers):
6560 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)

6576 * xfont.c (x_clear_errors):
6577 * xterm.c (x_frame_parm_handlers):
6578 Remove now-redundant extern decls.
6579 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
6580 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
6582 * xfaces.c: Remove unnecessary static decls.
6583 * xterm.c (updating_frame): Remove decl of nonexistent object.
6585 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
6586 when building globals.h, as the objects that are not built on
6587 this host are not needed to compile C files on this host.
6589 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
6591 * gtkutil.h: Remove prototype for x_wm_set_size_hint.

6618 (set_intervals_multibyte_1, set_intervals_multibyte):
6619 * keyboard.c (decode_timer):
6620 Use bool for boolean.
6621 * intervals.h, lisp.h, systime.h: Reflect above API changes.
6622 * editfns.c (struct info): Use 1-bit unsigned bitfields for booleans.

6629 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
6631 * makefile.w32-in (CCL_H, W32FONT_H): New macros.

6639 2012-09-01 Eli Zaretskii <eliz@gnu.org>
6641 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
6642 more than one grapheme cluster passed to the shaper: compute the
6643 offset adjustment values separately for each cluster. (Bug#11860)
6645 * image.c: Restore mistakenly removed inclusion of w32.h. Without
6646 it, GCC doesn't see prototypes of w32_delayed_load, and complains
6647 about implicit conversions from integer to pointer.
6649 2012-09-01 Daniel Colascione <dancol@dancol.org>
6651 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
6652 system used too early.
6654 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
6656 Better seed support for (random).

6692 window-system headers.
6694 * keyboard.h: Declare ignore_mouse_drag_p whenever we have a
6697 * keyboard.c: Include TERM_HEADER instead of listing all possible
6698 window-system headers.

6705 window system declarations.
6707 * frame.h: Move common functions here: set_frame_menubar,
6708 x_set_window_size, x_sync, x_get_focus_frame,
6709 x_set_mouse_position, x_set_mouse_pixel_position,
6710 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

6734 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
6736 Remove mark_ttys function and fix tty_display_info initialization.
6737 * lisp.h (mark_ttys): Remove prototype.
6738 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
6739 to mark_ttys because all possible values of 'top_frame' slot are
6740 the frames which are reachable from Vframe_list.
6741 * term.c (mark_ttys): Remove.
6742 (init_tty): Safely initialize 'top_frame' slot with Qnil.
6744 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
6746 Change struct frame bitfields from unsigned char to unsigned.
6747 * frame.h (struct frame): Change type of 'display_preempted',

6749 'auto_raise', 'auto_lower', 'no_split', 'explicit_name',
6750 'window_sizes_changed', 'mouse_moved' and 'pointer_invisible'
6751 bitfields from unsigned char to unsigned.

6766 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
6767 for GCC 4.7.1 x86-64.
6769 2012-08-30 Glenn Morris <rgm@gnu.org>
6771 * lread.c (init_lread): For out-of-tree builds, only add the
6772 source directory's site-lisp dir to the load-path if it exists,
6773 consistent with in-tree builds. (Bug#12302)
6775 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>
6777 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize

6787 (addSplit): Remove return self, declare return value as void.
6788 (clicked:): Remove return self, declare return value as void.
6789 Set dialog_return to button_values[seltag]. Code formatting change.

6791 Code formatting change.
6792 (timeout_handler:): Set timer_fired to YES.
6793 (runDialogAt:): Set timer_fired to NO.
6794 Handle click on close button as quit.
6796 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
6797 Add window_closed and button_values. Add void as return value for
6798 add(Button|String|Split). addButton takes int instead of Lisp_Object.
6799 Add process_dialog as new member.
6801 2012-08-28 Eli Zaretskii <eliz@gnu.org>
6803 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it
6804 is not one of the heaps we manage. (Bug#12242)

6865 Use bool for boolean.
6866 (clear_glyph_matrix_rows): Rename from enable_glyph_matrix_rows,
6867 and remove last int (actually boolean) argument, which was always 0.
6868 All callers changed.
6869 * dispextern.h, frame.h, lisp.h: Reflect above API changes.
6870 * dispextern.h (struct composition_it): Use bool for boolean.
6871 (struct glyph_matrix): Don't assume buffer sizes can fit in 'int'.
6872 (struct bidi_it): Use unsigned:1, not int, for boolean prev_was_pdf.
6873 * dired.c (file_name_completion):
6874 Use bool for boolean. (This was missed in an earlier change.)
6876 2012-08-27 Martin Rudalics <rudalics@gmx.at>
6878 * window.c (Fset_window_configuration): Revert first part of
6881 2012-08-27 Jan Djärv <jan.h.d@swipnet.se>
6883 * nsterm.h (NSPanel): New class variable dialog_return.
6885 * nsmenu.m (initWithContentRect:styleMask:backing:defer:):
6886 Initialize dialog_return.
6887 (windowShouldClose:): Use stop instead of stopModalWithCode.
6888 (clicked:): Ditto, and also set dialog_return (Bug#12258).
6889 (timeout_handler:): Use stop instead of abortModal. Send a dummy
6891 (runDialogAt:): Make ret Lisp_Object. Set it from dialog_return when
6894 2012-08-27 Paul Eggert <eggert@cs.ucla.edu>

6906 Use bool for booleans.
6907 * dired.c (file_name_completion):

6909 Omit int (actually boolean) argument. It wasn't being used.
6911 * composite.h, lisp.h: Reflect above API changes.

6936 Use bool for booleans.
6937 * coding.h, lisp.h: Reflect above API changes.
6938 * coding.c: Remove unnecessary static function decls.
6939 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
6940 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
6941 not a boolean 'int', since callers never look at the return value.
6942 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
6943 * coding.h (decoding_buffer_size, encoding_buffer_size)
6944 (emacs_mule_string_char): Remove unused extern decls.
6945 (struct iso_2022_spec, struct coding_system):
6946 Use 'unsigned int : 1' for boolean fields, since there's more than one.
6947 (struct emacs_mule_spec): Remove unused field 'full_support'.
6948 All initializations removed.
6949 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
6951 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
6953 Fix spare memory change (Bug#12286).
6954 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
6955 (valid_lisp_object_p): Likewise.
6957 2012-08-27 Martin Rudalics <rudalics@gmx.at>
6959 * window.c (Fset_window_configuration): Record any window's old
6960 buffer if it's replaced (see Bug#8789). If the new current
6961 buffer doesn't appear in the selected window, go to its old
6964 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
6966 Special MEM_TYPE_SPARE to denote reserved memory.
6967 * alloc.c (enum mem_type): New memory type.
6968 (refill_memory_reserve): Use new type for spare memory.
6969 This prevents live_cons_p and live_string_p from incorrect
6970 detection of uninitialized objects from spare memory as live.
6972 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
6975 * Makefile.in (.PHONY): versioclean -> versionclean.
6977 Remove unused external symbols.
6978 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
6979 * window.c (Qwindow_valid_p, decode_valid_window):
6980 Now static, not extern.
6981 * data.c (Qinterval): Remove; unused.
6982 (syms_of_data): Do not define 'interval'.
6983 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
6984 * window.h (decode_valid_window):
6987 * character.c, charset.c, chartab.c: Use bool for booleans.

6997 (char_table_set_range, optimize_sub_char_table)
6998 (map_sub_char_table):
6999 Use bool for boolean.
7000 * character.c (str_to_unibyte): Omit last boolean argument; it was
7001 always 0. All callers changed.
7002 * character.h, charset.h: Adjust to match previous changes.
7003 * character.h (char_printable_p): Remove decl of nonexistent function.
7004 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
7005 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
7006 are all boolean, so make them single-bit bitfields.
7008 * lisp.h (ASET): Remove attempt to detect side effects.
7009 It was meant to be temporary and it often doesn't work,
7010 because when IDX has side effects the behavior of IDX==IDX
7011 is undefined. See Stefan Monnier in
7012 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
7014 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
7016 * lisp.h (functionp): New function (extracted from Ffunctionp).
7017 (FUNCTIONP): Use it.
7018 * eval.c (Ffunctionp): Use it.
7020 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
7022 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
7023 as that's faster and simpler than static storage. Don't bother
7024 with the g_main_context_query overhead if g_main_context_pending
7025 says no events are pending.
7026 (gfds, gfds_size): Remove these static vars.
7027 (xgselect_initialize): Remove; no longer needed.
7028 All uses and decls removed.
7030 * emacs.c (fatal_error_signal_hook): Remove.
7031 All uses removed. This leftover from old code was always 0.
7033 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
7034 * casefiddle.c (casify_object, casify_region):
7035 * casetab.c (set_case_table):
7036 * category.c, category.h (word_boundary_p):
7037 * category.h (CHAR_HAS_CATEGORY):
7038 Use bool for booleans, instead of int.
7040 2012-08-25 Eli Zaretskii <eliz@gnu.org>
7042 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
7044 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
7046 On assertion failure, print backtrace if available.
7047 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
7048 (die) [ENABLE_CHECKING]: Print a backtrace if available.
7049 * Makefile.in (LIB_EXECINFO): New macro.
7052 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
7053 * bytecode.c (exec_byte_code):
7054 * callint.c (check_mark, Fcall_interactively):
7055 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
7056 (getenv_internal, sync_process_alive, call_process_exited):
7057 * lisp.h (USE_SAFE_ALLOCA):
7058 Use bool for booleans, instead of int.
7059 * lisp.h, process.h: Adjust prototypes to match above changes.
7060 * callint.c (Fcall_interactively): Don't assume the mark's
7061 offset fits in 'int'.
7063 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
7065 * buffer.c, buffer.h: Use bool for boolean.
7066 * buffer.c (reset_buffer_local_variables)
7067 (buffer_lisp_local_variables, Fset_buffer_modified_p)
7068 (Frestore_buffer_modified_p, Fset_buffer_multibyte):

7070 (overlay_touches_p, overlay_strings, Foverlay_put)
7071 (report_overlay_modification, call_overlay_mod_hooks):
7072 (mmap_enlarge, mmap_set_vars):
7073 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
7074 Use bool for booleans, instead of int.
7075 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
7076 since the 1-or-0 return value is always ignored anyway.
7077 (mmap_initialized_p):
7078 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
7079 * buffer.h, lisp.h: Adjust prototypes to match above changes.
7081 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
7083 * bidi.c: Use bool for boolean.
7084 This is a bit more readable, and makes the text segment of bidi.o
7085 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
7086 Presumably it's faster too.
7087 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
7089 (bidi_cache_find_level_change, bidi_cache_iterator_state)
7090 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
7091 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
7092 (bidi_explicit_dir_char, bidi_level_of_next_char)
7093 (bidi_find_other_level_edge, bidi_move_to_visually_next):
7094 Use bool for booleans, instead of int.
7095 * dispextern.h (bidi_init_it, bidi_paragraph_init)
7096 (bidi_unshelve_cache): Adjust decls to match code.
7098 2012-08-23 Martin Rudalics <rudalics@gmx.at>
7100 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
7103 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
7105 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
7106 * atimer.h: Include <stdbool.h>.
7108 2012-08-22 Dan Nicolaescu <dann@gnu.org>
7110 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
7111 compile time tests instead of run time tests on systems that do
7113 (FRAME_MAC_P): Remove leftover from deleted code.
7114 * frame.c (syms_of_frame): Remove leftover from deleted code.
7116 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
7118 * nsterm.m (insertText:): Don't clear modifiers if code is space.
7120 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
7122 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
7123 Otherwise, the compiler complains about (A?B:C) where B is void
7124 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
7125 (fontset_add): Return void, for FONTSET_ADD.
7127 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7129 * alloc.c: Use bool for booleans.
7130 (gc_in_progress, abort_on_gc)
7131 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
7132 (dont_register_blocks) [GC_MALLOC_CHECK]:
7133 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
7134 (check_string_bytes, make_specified_string, memory_full)
7135 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
7136 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
7137 (mark_stack, valid_pointer_p, make_pure_string)
7138 (Fgarbage_collect, survives_gc_p, gc_sweep):
7139 Use bool for booleans, instead of int.
7140 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
7141 Remove unused local.
7142 * alloc.c (PURE_POINTER_P):
7143 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
7144 * editfns.c (Fformat):
7145 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
7147 * fns.c (sweep_weak_table):
7148 * lisp.h (suppress_checking, push_message, survives_gc_p)
7149 (make_pure_string, gc_in_progress, abort_on_gc):
7150 * lread.c (readchar, read1):
7151 * print.c (Fprin1_to_string):
7152 * xdisp.c (push_message):
7153 Use bool for booleans affected directly or indirectly by
7156 Make recently-introduced setters macros.
7157 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
7158 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
7159 (set_fontset_default, set_fontset_fallback): Rename from their
7160 upper-case counterparts, and make them functions rather than macros.
7161 This is more consistent with the other recently-introduced setters.
7162 These don't need to be inline, since they're local.
7164 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
7166 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
7167 the loop (Bug#12247).
7169 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7171 * lisp.h (vcopy): Use memcpy rather than our own loop.
7172 This fixes a performance regression introduced by the recent
7173 addition of vcopy. This means 'vcopy' will need to be modified
7174 for a copying collector, but that's OK. Also, tighten the
7175 checking in the assertion.
7177 2012-08-21 Eli Zaretskii <eliz@gnu.org>
7179 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
7180 components for RTL text (Bug#11860). Adjust X-OFFSET of each
7181 non-base glyph for the width of the base character, according to
7182 what x_draw_composite_glyph_string_foreground expects.
7183 Generate WADJUST value according to composition_gstring_width's
7184 expectations, to produce correct width of the composed character.
7185 Reverse the sign of the DU offset produced by ScriptPlace.
7187 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7189 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
7191 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
7193 Avoid direct writes to contents member of struct Lisp_Vector.
7194 * lisp.h (vcopy): New function to copy data into vector.
7195 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
7196 * fns.c (Ffillarray): Use ASET.
7197 * keyboard.c (timer_check_2): Use AREF and ASET.
7198 (append_tool_bar_item, Frecent_keys): Use vcopy.
7199 * lread.c (read_vector): Use ASET.
7200 * msdos.c (Frecent_doskeys): Use vcopy.
7201 * xface.c (Finternal_copy_lisp_face): Use vcopy.
7202 (Finternal_merge_in_global_face): Use ASET and vcopy.
7203 * xfont.c (xfont_list_pattern): Likewise.
7205 2012-08-21 Martin Rudalics <rudalics@gmx.at>
7207 * window.c (Fwindow_point): For the selected window always return
7208 the position of its buffer's point.
7209 (Fset_window_point): For the selected window always go in its
7210 buffer to the specified position.
7212 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
7214 Setter macros for fontsets.
7215 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
7216 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
7217 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
7220 2012-08-20 Glenn Morris <rgm@gnu.org>
7222 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
7223 Don't assume that `ln -f' works.
7225 2012-08-20 Eli Zaretskii <eliz@gnu.org>
7227 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
7228 and later about non-assignments with no effect. See discussion at
7229 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
7232 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7234 Inline setter functions for Lisp_Objects slots of struct specbinding.
7235 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
7238 2012-08-20 Martin Rudalics <rudalics@gmx.at>
7240 * window.c (select_window): Always make selected window's buffer
7243 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7245 Use AREF and ASET for docstrings of category tables.
7246 * category.h (CATEGORY_DOCSTRING): Use AREF.
7247 (SET_CATEGORY_DOCSTRING): Use ASET.
7248 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
7250 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7252 Inline setter functions for hash table members.
7253 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
7254 (set_hash_hash, set_hash_index): Rename with _slot suffix.
7255 (set_hash_key_and_value, set_hash_index, set_hash_next)
7256 (set_hash_hash): New functions.
7257 * charset.c, fns.c: Adjust users.
7259 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7261 Inline getter and setter functions for per-buffer values.
7262 * buffer.h (per_buffer_default, set_per_buffer_default)
7263 (per_buffer_value, set_per_buffer_value): New functions.
7264 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
7265 * buffer.c, data.c: Adjust users.
7267 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
7269 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
7271 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
7273 Rely on <config.h> + <unistd.h> to declare 'environ',
7274 as gnulib does this if the system doesn't.
7275 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
7276 Remove declaration. MS-Windows declares it on stdlib.h which is
7277 included by conf_post.h.
7278 * emacs.c (environ) [DOUG_LEA_MALLOC]:
7279 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
7280 * vm-limit.c: Include <unistd.h>, for 'environ'.
7282 * unexaix.c, unexcoff.c: Include "mem-limits.h".
7283 (start_of_data): Remove decl; mem-limits.h provides it.
7285 * xdisp.c (handle_invisible_prop): Make it a bit faster
7286 and avoid a gcc -Wmaybe-uninitialized diagnostic.

7699 Use bool, not int, for Lisp booleans.
7700 This is more natural, and on my platform (GCC 4.7.1 x86-64) it
7701 makes Emacs a bit smaller and presumably a bit faster.

7703 (struct Lisp_Boolfwd, defvar_bool):
7704 * lread.c (defvar_bool): Use bool, not int, for Lisp booleans.

8159 directory, ignore the /*/i386/ tail in Vinvocation_directory, for
8160 compatibility with Posix platforms.
8161 (main): Move the call to check_windows_init_file to here from
8163 (decode_env_path) [WINDOWSNT]: Expand the %emacs_dir%/ prefix, if
8164 any, in the DEFALT argument into the root of the Emacs build or
8165 installation tree, as appropriate.
8167 * callproc.c (init_callproc_1): Call decode_env_path instead of
8168 doing its equivalent by hand.
8169 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
8170 the code that sets Vexec_path run on MS-Windows.
8172 * lread.c (init_lread): Add comments to #ifdef's.
8174 * msdos.c (dos_set_window_size, IT_update_begin)
8175 (IT_frame_up_to_date, IT_set_frame_parameters): Use FVAR and WVAR
8176 instead of direct references.
8178 2012-08-04 Paul Eggert <eggert@cs.ucla.edu>
8180 Export DEFAULT_REHASH_* to GDB.
8181 * lisp.h (DEFAULT_REHASH_THRESHOLD, DEFAULT_REHASH_SIZE):
8182 Now constants, not macros.
8184 2012-08-03 Paul Eggert <eggert@cs.ucla.edu>
8186 Remove unnecessary casts involving pointers.
8187 These casts are no longer needed now that we assume C89 or later,
8188 since they involve casting to or from void *.
8189 * alloc.c (make_pure_string, make_pure_c_string, pure_cons)
8190 (make_pure_float, make_pure_vector):
8191 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP):

8200 (x_get_window_property, x_get_window_property_as_lisp_data):
8201 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
8202 Remove unnecessary pointer casts.
8203 * alloc.c (record_xmalloc): New function.
8204 * lisp.h (record_xmalloc): New decl.
8205 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
8206 more like a function. This is because the pointer cast is not
8207 needed. All uses changed.
8208 * print.c (print_string, print_error_message): Avoid length recalc.
8210 Improve fix for macroexp crash with debugging (Bug#12118).
8211 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
8212 ARRAY_MARK_FLAG when checking subscripts, because ASET is
8213 not supposed to be invoked from the garbage collector.
8214 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
8215 (gc_aset): New function, which is like ASET but can be
8216 used in the garbage collector.
8217 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)
8218 (set_hash_index): Use it instead of ASET.

8229 (GetSecurityInfo_Proc, CreateSymbolicLink_Proc): New typedefs.
8230 (map_w32_filename): Improve commentary. Simplify switch.
8231 (SYMBOLIC_LINK_FLAG_DIRECTORY): Define if not defined in system
8232 headers (most versions of MinGW w32api don't).
8233 (get_security_info, create_symbolic_link)
8234 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
8236 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
8237 in the argument file name.

8239 GetFileAttributes fails with network-related error codes.
8240 (sys_rename): Diagnose renaming of a symlink when the user doesn't
8241 have the required privileges.
8242 (get_file_security_desc_by_name): Rename from
8243 get_file_security_desc.
8244 (stat_worker): New function, with most of the guts of 'stat', and
8245 with addition of handling of symlinks and support for 'lstat'.
8246 If possible, get file's attributes and security information by
8247 handle, not by name. Produce S_IFLNK bit for symlinks, when
8248 called from 'lstat'.
8249 (stat, lstat): New functions, call 'stat_worker'.
8250 (symlink, readlink, careadlinkat): Rewritten to create and resolve
8251 symlinks when the underlying filesystem supports them.
8253 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
8255 Fix macroexp crash on Windows with debugging (Bug#12118).
8256 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
8257 checking subscripts; problem introduced with the recent
8258 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
8259 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
8260 since it's used in non-static inline functions now.
8262 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
8263 Don't assume buffer size fits in 'int'. Remove unused local.
8265 Use C99-style 'extern inline' if available.

8276 * dispextern.h, lisp.h, systime.h:
8277 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
8278 * alloc.c (LISP_INLINE):
8279 * buffer.c (BUFFER_INLINE):
8280 * category.c (CATEGORY_INLINE):
8281 * character.c (CHARACTER_INLINE):
8282 * charset.c (CHARSET_INLINE):
8283 * composite.c (COMPOSITE_INLINE):
8284 * dispnew.c (DISPEXTERN_INLINE):
8285 * sysdep.c (SYSTIME_INLINE):
8286 Define to EXTERN_INLINE, so that the corresponding functions
8287 are compiled into code.
8288 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
8289 (INLINE_HEADER_END): New macros.
8290 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

8310 hard-coding the path separator.
8312 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
8314 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
8315 This how ASET and AREF are supposed to work, and makes
8316 it easier to think about future improvements. See
8317 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
8318 * charset.h (set_charset_attr): New function.
8319 All lvalue-style uses of CHARSET_DECODER etc. changed to use it.
8320 * lisp.h (ASET): Rewrite so as not to use AREF in an lvalue style.

8733 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
8734 enumeration constants, as PURE and HEAP are too general, and clash
8735 with other headers and sources, such as gmalloc.c and the
8736 MS-Windows system headers. All users changed.
8738 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
8740 Revert last save_excursion_save and save_excursion_restore changes.
8741 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

8754 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
8755 arms of an 'if', not using conditional expressions; otherwise GDB
8756 complains about the types in the unevaluated arm when the argument
8757 is an integer literal.
8758 (xgetint): Simplify expression.
8759 * alloc.c (gdb_make_enums_visible): New constant. This ports to
8760 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
8761 Zaretskii in <http://bugs.gnu.org/12036#13>.
8762 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
8763 needed now that we have gdb_make_enums_visible.
8764 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
8765 (enum enum_USE_LSB_TAG):
8766 New enum types, packaging up enums that need to be exported to GDB.

8808 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
8809 emacs.c, as this is a more-suitable home. Had this been done earlier
8810 the fix for 12036 would have avoided some of the problems noted in
8811 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
8812 would have been more obvious.
8813 * emacs.c: Do not include <verify.h>; no longer needed.
8814 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
8815 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
8816 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):

8822 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
8823 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
8824 not be usable in #if. This simplifies things.
8826 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
8828 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.

8833 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
8834 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
8835 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
8836 Adjust to changes in lisp.h and emacs.c, by using
8837 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
8838 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
8839 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
8840 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
8841 instead of gdb_valbits.
8842 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
8843 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
8844 instead of gdb_array_mark_flag.
8845 (xboolvector): Get size from $->size, not $->header.size.
8846 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
8847 (xreload, hook-run, hookpost-run): Remove.
8848 * emacs.c: Include <verify.h>.
8849 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
8850 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
8852 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
8853 (gdb_USE_LSB_TAG): New enum constants.
8854 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
8855 Also define these as enum constants, so they're visible to GDB.
8856 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
8857 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
8858 as constants, so they're visible to GDB.

8861 Now enum constants, not macros, so they're visible to GDB.
8862 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
8863 more convenient now. All uses changed.
8864 (VALMASK) [USE_LSB_TAG]: Also define in this case.
8865 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
8867 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

8874 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
8875 add argument, tune behavior, and adjust all callers.
8877 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
8879 Use typedef for EMACS_INT, EMACS_UINT.
8880 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
8881 than macros. This simplifies debugging in the usual case, since
8882 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
8883 and it allows expressions involving EMACS_INT casts.
8884 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
8886 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

8898 Adjust buffer text indirection counters at the end of Fkill_buffer.
8899 * buffer.c (Fkill_buffer): Adjust indirection counters when the
8900 buffer is definitely dead. This should really fix an issue reported
8901 by Christoph Scholtes again. (Bug#12007).
8902 (init_buffer_once): Initialize indirection counters of
8903 buffer_defaults and buffer_local_symbols (for sanity and safety).
8905 2012-07-24 Eli Zaretskii <eliz@gnu.org>
8907 * xdisp.c (init_iterator): Don't compute dimensions of truncation
8908 and continuation glyphs on tooltip frames, leave them at zero.

8936 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
8938 Swap buffer text indirection counters in Fbuffer_swap_text.
8939 * buffer.c (Fbuffer_swap_text): Swap indirections too.
8940 This avoids crash reported by Christoph Scholtes at
8941 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
8943 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
8945 * nsmenu.m (Popdown_data): New struct.
8946 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
8948 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
8949 (initWithContentRect): Make imgView and contentView non-static
8950 and autorelease them. Also autorelease img and matrix (Bug#12005).
8951 (dealloc): Remove (Bug#12005).
8953 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
8955 Adjust consing_since_gc when objects are explicitly freed.

8968 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
8970 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
8971 as it's limited by the amount of memory, not by INT_MAX.
8973 2012-07-21 Eli Zaretskii <eliz@gnu.org>
8975 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
8976 in special-event-map. See the discussion at

9521 and continuation glyphs alike.
9522 (produce_special_glyphs) [HAVE_WINDOW_SYSTEM]: Produce a stretch
9523 glyph of a suitably computed width, to align the special glyphs at

9699 * s/aix4-2.h (unix): Remove; no longer needed.
9701 EMACS_TIME simplification (Bug#11875).
9702 This replaces macros (which typically do not work in GDB)
9703 with functions, typedefs and enums, making the code easier to debug.
9704 The functional style also makes code easier to read and maintain.
9705 * systime.h: Include <sys/time.h> on all hosts, not just if
9706 WINDOWSNT, since 'struct timeval' is needed in general.

9721 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
9722 (add_emacs_time, sub_emacs_time): New functions.
9723 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.

9746 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
9747 Prefer snprintf to strncpy.
9748 * nsterm.m (ns_term_init):
9749 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
9750 * nsterm.m (ns_term_init):
9751 Avoid the need for strncpy, by using build_string or
9752 make_unibyte_string directly. Use dtoastr, not snprintf.
9753 * process.c (Fmake_network_process): Diagnose service names that
9754 are too long, rather than silently truncating them or creating
9755 non-null-terminated names.

9772 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
9773 where argument type is known to be a Lisp_Cons.

9828 O_RDONLY already includes it).
9830 Stop ns builds setting the EMACSLOADPATH environment variable.
9831 * nsterm.m (ns_load_path): Rename from ns_init_paths.
9832 Now it does not set EMACSLOADPATH, just returns the load-path string.

9834 * lread.c [HAVE_NS]: Include nsterm.h.
9835 (init_lread) [HAVE_NS]: Use ns_load_path.

9845 (ns_init_paths): Do not set EMACSPATH.

9905 Move marker debugging code under MARKER_DEBUG.
9906 * marker.c (MARKER_DEBUG): Move marker debugging code under
9907 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
9908 for bootstrap with --enable-checking (~3x slowdown reported

9945 (x_set_font) [!HAVE_X_WINDOWS]:
9946 * image.c (xpm_load_image) [HAVE_NS]:
9947 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
9948 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
9949 Remove unused local.
9950 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
9951 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
9952 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
9953 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
9954 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
9955 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
9956 Fix pointer signedness problem.
9957 * xfaces.c (FRAME_X_FONT_TABLE):
9958 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
9960 2012-07-07 Glenn Morris <rgm@gnu.org>
9962 * lread.c (load_path_check): New function, split from init_lread.
9963 (init_lread): Reorganize. Motivation:
9964 If EMACSLOADPATH is set, check/warn about that rather than the
9965 defaults, which we are not going to use. Hence we can remove
9966 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
9967 Don't warn if site-lisp directories are missing.
9968 If not installed, start from a blank load-path, since
9969 PATH_LOADSEARCH refers to the eventual installation directories.
9971 2012-07-07 Eli Zaretskii <eliz@gnu.org>
9973 Support truncation and continuation glyphs on GUI frames, when
9974 fringes are disabled. (Bug#11832)
9975 * xdisp.c (init_iterator): Get dimensions of truncation and
9976 continuation glyphs even if on GUI frames.
9977 Adjust it->last_visible_x on GUI frames when the left or right fringes,
9978 or both, are absent.
9979 (start_display, move_it_in_display_line_to): Handle the case of a
9980 GUI frame without a fringe to display continuation or truncation
9982 (insert_left_trunc_glyphs): Support GUI frames: make sure
9983 truncation glyphs overwrite enough glyphs from the current line to
9984 have sufficient space in pixels.
9985 (display_line): Support truncation and continuation glyphs on GUI
9986 frames. If some spare pixels are left on the line after inserting
9987 the truncation glyphs, fill that space with a stretch glyph of a
9988 suitably computed width.
9990 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
9991 produce_glyphs, to support GUI sessions.
9993 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
9995 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
9997 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
9999 Do not require float-time's arg to fit in time_t (Bug#11825).
10000 This works better on hosts where time_t is unsigned, and where
10001 float-time is applied to the (negative) difference between two times.
10002 * editfns.c (decode_time_components): Last arg is now double *,
10003 not int *, and means to store all the result as a double, without
10004 worrying about whether the seconds part fits in time_t.
10005 All callers changed.
10006 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
10007 All callers changed.
10008 (Ffloat_time): Do not fail merely because the specified time falls
10009 outside of time_t range.
10011 2012-07-07 Glenn Morris <rgm@gnu.org>
10013 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
10014 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
10015 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
10017 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
10019 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
10020 Update dependencies.
10022 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
10024 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
10026 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
10027 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
10028 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
10029 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
10030 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
10031 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
10033 * xfont.c (compare_font_names): Redo to omit the need for casts.
10035 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
10037 * xfns.c (Fx_change_window_property): Doc fix.
10038 * w32fns.c (Fx_change_window_property): Doc fix.
10040 * w32fns.c (Fx_window_property): Accept the same arguments as the
10041 X Windows version. Doc fix.
10042 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
10044 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
10045 Eli Zaretskii <eliz@gnu.org>
10047 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
10048 Windows-specific code from nt/config.nt moved here.
10049 Obsolete settings removed.
10051 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
10053 * process.c: Avoid unnecessary calls to gettime.
10054 (wait_reading_process_output): Don't get the time of day
10055 when gobbling data immediately and not waiting, as there's no need
10056 for it in that case. This removes a FIXME.
10058 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
10060 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
10061 is defined (Bug#11768).
10063 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10065 Fix marker debugging code.
10066 * marker.c (byte_char_debug_check): Do not perform the check
10067 if buffer is not multibyte.
10068 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
10069 Call byte_char_debug_check with correct arguments.
10071 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10073 Compile marker debugging code only if ENABLE_CHECKING is defined.
10074 * marker.c (byte_char_debug_check, count_markers):
10075 Use only if ENABLE_CHECKING is defined.
10076 (byte_debug_flag): Remove.
10077 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
10078 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
10080 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10082 Avoid code repetition in marker-related functions.
10083 * marker.c (attach_marker): New function.
10084 (Fset_marker, set_marker_restricted, set_marker_both)
10085 (set_marker_restricted_both): Use it.
10086 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
10087 Consistently rename charno to charpos.
10088 (marker_position): Add eassert.
10089 (marker_byte_position): Convert to eassert.
10091 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10093 Simplify list operations in unchain_overlay and unchain_marker.
10094 * buffer.c (unchain_overlay): Simplify. Add comment.
10095 * marker.c (unchain_marker): Simplify. Fix comments.
10097 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10099 Introduce fast path for the widely used marker operation.

10102 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
10103 * composite.c (autocmp_chars): Likewise.
10104 * editfns.c (buildmark): Remove.
10105 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
10106 (save_restriction_save): Use build_marker.
10107 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
10108 * window.c (save_window_save): Likewise.
10110 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10112 Do not use Fdelete_overlay in delete_all_overlays
10113 to avoid redundant calls to unchain_overlay.
10114 * buffer.c (drop_overlay): New function.
10115 (delete_all_overlays, Fdelete_overlay): Use it.
10116 * minibuf.c (get_minibuffer): Fix comment.
10118 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
10120 Port to OpenBSD 5.1 amd64.
10121 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
10122 This is needed for OpenBSD, and should be harmless on all BSD systems.
10123 Also, include <sys/sysctl.h>, as it should be available on all
10124 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
10125 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
10126 use p_pid member, not kp_proc.pid.
10128 2012-07-06 Glenn Morris <rgm@gnu.org>
10130 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
10132 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
10134 More xmalloc and related cleanup.
10135 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
10136 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:
10137 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, fns.c:

10143 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
10145 Omit needless casts involving void * pointers and allocation.
10146 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
10147 as the former is more robust if P's type is changed.
10148 Prefer xzalloc to xmalloc + memset 0.
10149 Simplify malloc-or-realloc to realloc.
10150 Don't worry about xmalloc returning a null pointer.
10151 Prefer xstrdup to xmalloc + strcpy.
10152 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
10154 * keyboard.c (apply_modifiers_uncached): Prefer local array to
10155 alloca of a constant.
10157 2012-07-05 Eli Zaretskii <eliz@gnu.org>
10159 * xdisp.c (display_line): Fix horizontal pixel coordinates when
10160 hscroll is larger than the line width. Fixes long and futile
10161 looping inside extend_face_to_end_of_line (on a TTY) producing
10162 glyphs that are not needed and thrown away.
10164 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
10166 * marker.c (set_marker_restricted_both): Simplify by using
10169 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
10171 * editfns.c (region_limit): Simplify by using clip_to_bounds.
10173 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
10175 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
10176 not defined (Bug#11768).
10177 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
10178 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
10179 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
10180 followed by gtk_box_set_homogeneous (Bug#11768).
10181 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
10182 (update_theme_scrollbar_width, xg_create_scroll_bar):
10183 Use gtk_scrollbar_new (Bug#11768).
10184 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
10185 (is_box_type): New function (Bug#11768).
10186 (xg_tool_item_stale_p): Call is_box_type.
10187 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
10188 with default display (Bug#11768).
10190 2012-07-05 Eli Zaretskii <eliz@gnu.org>
10192 * xdisp.c (window_hscroll_limited): New function.
10193 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
10194 coordinates when window's hscroll is set to insanely large
10195 values. (Bug#11857)
10197 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
10199 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
10200 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.

10258 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
10260 * fileio.c (time_error_value): Check the right error number.
10261 Problem reported by Troels Nielsen in
10262 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
10264 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10266 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
10267 This should be fixed in a better way; see Eli Zaretskii in
10268 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
10269 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
10271 * fileio.c (time_error_value): Rename from special_mtime.
10272 The old name's problems were noted by Eli Zaretskii in
10273 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
10275 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
10276 This variable's comment says Emacs needs at least one GDB-visible
10277 symbol of type enum pvec_type, to work around GDB problems.
10278 The symbol's value doesn't matter.
10280 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
10281 that causes compilation to fail on pre-C99 compilers.
10283 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
10285 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
10286 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
10288 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10290 * buffer.c (init_buffer_once): Fix initialization of
10291 headers for buffer_defaults and buffer_local_symbols.
10292 Reported by Juanma Barranquero <lekktu@gmail.com>.
10294 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
10296 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
10297 * lisp.h (enum pvec_type): Use fewer bits.
10298 (PSEUDOVECTOR_SIZE_BITS): New constant.
10299 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
10300 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
10301 change in pvec_type.
10302 (PSEUDOVECTOR_TYPEP): New macro.
10303 (TYPED_PSEUDOVECTORP): Use it.
10304 * fns.c (internal_equal): Adapt code to extract pvectype.
10305 * emacs.c (gdb_pvec_type): Update type.
10306 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
10307 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
10308 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
10309 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
10310 (sweep_vectors): Use it. Use local var `total_bytes' instead of
10311 abusing vector->header.next.nbytes.
10312 (live_vector_p): Use PVEC_TYPE.
10313 (mark_object): Adapt code to extract pvectype. Use switch.
10315 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10317 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
10318 Tighten new eassert a bit.
10320 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10322 Fix compilation with --enable-gcc-warnings and -O1
10323 optimization level.
10324 * doprnt.c (doprnt): Change type of tem to int, initialize
10325 to avoid compiler warning. Add eassert.
10326 * search.c (simple_search): Initialize match_byte to avoid
10327 compiler warning. Add eassert.
10329 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10331 Avoid weird behavior with large horizontal scrolls.
10332 Without this change, for example, large hscroll values would
10333 mess up Emacs's display on Fedora 15 x86, presumably due to
10334 overflows in int calculations in the display code.
10335 Also, if buffers had long lines, Emacs would freeze.
10336 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
10337 (set_window_hscroll): New function, containing the old guts of
10338 Fset_window_hscroll. Return the clipped value.
10339 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
10340 This avoids the need to check against PTRDIFF_MAX.
10342 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
10344 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10346 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
10348 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10350 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
10351 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
10352 since GCC 4.4.6 issues a bogus warning for them.
10354 Fix bugs in file timestamp newness comparisons.
10355 * fileio.c (Ffile_newer_than_file_p):
10356 * lread.c (Fload): Use full timestamp resolution of files,
10357 not just the 1-second resolution, so that files that are only
10358 slightly newer still count as newer.
10359 * fileio.c (Ffile_newer_than_file_p): Don't assume file
10360 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
10362 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
10364 * fileio.c: Improve handling of file time marker. (Bug#11852)
10365 (special_mtime): New function.
10366 (Finsert_file_contents, Fverify_visited_file_modtime):
10367 Use it to set special mtime values consistently.
10369 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
10371 * fileio.c (Finsert_file_contents): Properly handle st_mtime
10372 marker for non-existing file. (Bug#11852)
10374 2012-07-03 Glenn Morris <rgm@gnu.org>
10376 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
10377 and did not make it into globals.h).
10379 2012-07-03 Tom Tromey <tromey@redhat.com>
10381 * window.c (Fset_window_margins, Fset_window_fringes)

10417 2012-07-03 Glenn Morris <rgm@gnu.org>
10419 * lisp.h (Frandom): Make it visible to C.
10420 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
10421 buffer for invisible buffers. (Bug#1229)
10423 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10425 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
10426 values which aren't power of 2.
10427 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
10428 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
10431 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
10433 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
10435 * alloc.c (mark_object): Revert part of last patch to use `switch'.
10437 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10439 * alloc.c (allocate_vector_block): Remove redundant
10440 calls to mallopt if DOUG_LEA_MALLOC is defined.
10441 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
10442 avoid calls to mallopt if zero_vector is returned.
10444 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10446 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
10447 is enabled, avoid dereferencing NULL current_sblock if
10450 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10452 Cleanup basic buffer management.
10453 * buffer.h (struct buffer): Change layout to use generic vector
10454 marking code. Fix some comments. Change type of 'clip_changed'
10455 to bitfield. Remove unused #ifndef old.
10456 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
10457 (GET_OVERLAYS_AT): Fix indentation.
10458 (for_each_per_buffer_object_at): New macro.
10459 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
10460 (Fbuffer_local_variables): Use it.
10461 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
10462 * alloc.c (allocate_buffer): Adjust to match new layout of
10463 struct buffer. Fix comment.
10464 (mark_overlay): New function.
10465 (mark_buffer): Use it. Use mark_vectorlike to mark normal
10466 Lisp area of struct buffer.
10467 (mark_object): Use it. Adjust marking of misc objects
10468 and related comments.
10470 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
10472 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
10473 wrapper that is not needed because the wrapped code is a no-op (zero
10474 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
10475 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
10477 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
10479 * alloc.c (mark_buffer): Simplify. Remove prototype.
10480 (mark_object): Add comment. Reorganize marking of vector-like
10481 objects. Use CHECK_LIVE for all vector-like objects except buffers
10482 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
10483 Avoid redundant calls to mark_vectorlike for bool vectors.
10485 2012-06-30 Glenn Morris <rgm@gnu.org>
10487 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
10489 * epaths.in (PATH_SITELOADSEARCH): New.
10490 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
10491 This is rather than relying on --enable-locallisppath elements
10492 having "site-lisp" in their names. (Bug#10208#25, 11658)
10494 2012-06-30 Eli Zaretskii <eliz@gnu.org>
10496 * w32proc.c (sys_select): Accept and ignore one more argument.
10498 * w32.c (emacs_gnutls_pull): Call select with one more argument.
10500 * sysselect.h [DOS_NT]: Don't include sys/select.h.
10501 (pselect) [!MS_DOS]: Redirect to sys_select.
10503 * sysdep.c: Don't include dos.h and dosfns.h.
10505 * process.c (sys_select):
10506 * msdos.c (sys_select): Accept one more argument and ignore it.
10508 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
10509 adapt data types and code to that.
10512 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
10513 which clashes with the gnulib function of the same name.
10515 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
10517 * font.c (font_style_to_value, font_style_symbolic)
10518 (font_prop_validate_style): Add type checks for values in
10521 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
10523 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
10526 2012-06-29 Eli Zaretskii <eliz@gnu.org>
10528 * xdisp.c (try_window_id): Undo last change.
10530 * w32.c (getwd): Adjust commentary about startup_dir.
10531 (init_environment): Always call sys_access, even in non-MSVC
10532 builds. Don't chdir to the directory of the Emacs executable.
10533 This undoes code from 1997 which was justified by the need to
10534 "avoid conflicts when removing and renaming directories". But its
10535 downside was that every relative file name was being interpreted
10536 relative to the directory of the Emacs executable, which can never
10537 be TRT. In particular, it broke sys_access when called with
10538 relative file names.
10539 (sys_access): Map GetLastError to errno.
10541 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>

10547 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
10550 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
10552 * gnutls.c (emacs_gnutls_handshake):
10553 Add QUIT to make the loop interruptible.
10555 2012-06-29 Glenn Morris <rgm@gnu.org>
10557 * charset.c (init_charset): Make lack of etc/charsets fatal.

10565 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
10566 undefined. Convert from xassert to eassert.
10567 * nsmenu.m: Convert from xassert to eassert.
10568 * nsterm.m: Likewise.
10570 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>

10574 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
10576 Avoid integer overflow on scroll-left and scroll-right.
10577 * window.c (HSCROLL_MAX): New macro.
10578 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
10579 overflow when requested scroll falls outside ptrdiff_t range.
10581 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
10583 * window.h (struct window): Change type of 'hscroll',
10584 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
10585 'last_modified' and 'last_overlay_modified' to EMACS_INT.
10586 Adjust users accordingly.
10587 * xdisp.c (try_cursor_movement): Replace type check with eassert.
10588 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
10589 from EMACS_INT to ptrdiff_t.
10590 (make_window): Omit redundant initialization.

10609 Fix GLYPH_DEBUG usage assuming that it may be undefined,
10610 adjust comments accordingly.

10692 when building with Clang.

10723 * alloc.c: Remove build_string.

10731 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
10733 Use sprintf return value instead of invoking strlen on result.
10734 In the old days this wasn't portable, since some sprintf
10735 implementations returned char *. But they died out years ago and
10736 Emacs already assumes sprintf returns int.
10737 Similarly for float_to_string.
10738 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

10744 * xdisp.c (message_dolog):
10745 * xfns.c (syms_of_xfns):
10746 Use sprintf or float_to_string result to avoid need to call strlen.
10747 * data.c (Fnumber_to_string):
10748 Use make_unibyte_string, since the string must be ASCII.
10749 * lisp.h, print.c (float_to_string): Now returns int length.
10750 * term.c (produce_glyphless_glyph):
10751 Use sprintf result rather than recomputing it.
10753 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
10754 * Makefile.in (ALL_CFLAGS):
10755 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

10761 strcasecmp if available.

10782 * xfns.c (x_window): Remove redundant cast.
10784 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
10786 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
10787 `const char *' to `char *' to avoid compiler warning.
10789 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
10791 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
10792 instead of truncating it to 63 (admittedly a generous limit).
10794 * process.c: Fix spelling and caps in comments.
10796 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
10798 * emacs.c (setpgrp): Remove definition, unused.

10845 Remove unnecessary forward decls.
10847 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>

10855 This improves on the previous patch, which introduced a bug
10856 when time_t is unsigned and as wide as intmax_t.
10857 See <http://bugs.gnu.org/9000#51>.

10888 language ID in the event parameters.
10890 * w32term.c (w32_read_socket): Put the new keyboard codepage into
10891 event.code, not the obscure "character set ID".
10893 2012-06-23 Chong Yidong <cyd@gnu.org>
10895 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.

10922 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
10924 Support higher-resolution time stamps (Bug#9000).
10925 The time stamps are only nanosecond-resolution at the C level,
10926 since that's the best that any real-world system supports now.
10927 But they are picosecond-resolution at the Lisp level, as that's
10928 easy, and leaves room for future OS improvements.
10930 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
10933 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
10934 Don't get current time unless it's needed.
10936 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
10937 now provides it if it's absent.
10938 (start_atimer): Port to higher-res time stamps.
10939 Check for time stamp overflow. Don't get current time more
10940 often than is needed.
10942 * buffer.h (struct buffer): Buffer modtime now has high resolution.
10943 Include systime.h, not time.h.
10944 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
10946 * dired.c: Include stat-time.h.
10947 (Ffile-attributes): File times now have higher resolution.
10949 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
10950 (struct image): Timestamp now has higher resolution.
10952 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
10953 has at least microseconds now. All uses removed.
10954 (update_frame, update_single_window, update_window, update_frame_1)
10955 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
10956 (duration_to_sec_usec): Remove; no longer needed.
10958 * editfns.c (time_overflow): Now extern.
10959 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)

10964 (decode_time_components, lisp_seconds_argument): New functions.
10965 (make_time): Now static.
10966 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
10967 Report an error if the time is invalid, rather than having the caller
10970 * fileio.c: Include <stat-time.h>
10971 (Fcopy_file): Copy higher-resolution time stamps.
10972 Prefer to set the time stamp via a file descriptor if that works.
10973 (Fset_file_times, Finsert_file_contents, Fwrite_region)
10974 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
10975 (Fvisited_file_modtime, Fset_visited_file_modtime):
10976 Support higher-resolution time stamps.
10978 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
10980 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
10982 * image.c (prepare_image_for_display, clear_image_cache)
10983 (lookup_image): Port to higer-resolution time stamps.
10985 * keyboard.c (start_polling, bind_polling_period):
10986 Check for time stamp overflow.
10987 (read_char, kbd_buffer_get_event, timer_start_idle)
10988 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
10989 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
10990 Port to higher-resolution time stamps. Do not assume time_t is signed.
10991 (decode_timer): New function. Timers are now vectors of length 9,
10992 not 8, to accommodate the picosecond component.
10993 (timer_check_2): Use it.
10995 * nsterm.m (select_timeout, timeval_subtract): Remove.
10996 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
10997 as they're a bit more accurate and handle overflow better.
10998 (ns_select): Change prototype to be compatible with pselect.
10999 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
11000 * nsterm.h (ns_select): Adjust prototype.
11002 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
11003 us-resolution time stamps.
11004 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
11006 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
11008 * lisp.h (time_overflow): New decl.
11009 (wait_reading_process_output): First arg is now intmax_t, not int,
11010 to accommodate larger waits.
11012 * process.h (struct Lisp_Process.read_output_delay):
11013 Now counts nanoseconds, not microseconds.
11014 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
11016 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
11017 (wait_reading_process_output):
11018 Port to ns-resolution time stamps.
11019 (Faccept_process_output, wait_reading_process_output):
11020 Check for time stamp overflow. Do not assume time_t is signed.
11021 (select_wrapper): Remove; we now use pselect.
11022 (Fprocess_attributes): Now generates ns-resolution time stamps.
11024 * sysdep.c: Include utimens.h. Don't include utime.h
11025 or worry about struct utimbuf; gnulib does that for us now.
11026 (gettimeofday): Remove; gnulib provides a substitute.
11027 (make_timeval): New function.
11028 (set_file_times): Now sets ns-resolution time stamps.
11029 New arg FD; all uses changed.
11030 (time_from_jiffies, ltime_from_jiffies, get_up_time)
11031 (system_process_attributes):
11032 Now returns ns-resolution time stamp. All uses changed.
11033 Check for time stamp overflow.
11035 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
11036 provides a substitute now.
11038 * systime.h: Include timespec.h rather than sys/time.h and time.h,
11039 since it guarantees struct timespec.
11040 (EMACS_TIME): Now struct timespec, so that we can support
11041 ns-resolution time stamps.
11042 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
11043 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
11044 (EMACS_USECS): Remove.
11045 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
11046 so multiply the arg by 1000 before storing it.
11047 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
11049 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
11050 Port to ns-resolution time stamps.
11051 (EMACS_TIME_NEG_P): Remove; replaced by....

11054 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
11055 (set_file_times, make_time, lisp_time_argument): Adjust signature.
11056 (make_timeval, make_lisp_time, decode_time_components): New decls.
11057 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
11058 that it mishandled time_t overflow. You can't compare by subtracting!
11059 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
11060 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
11062 * term.c: Include <sys/time.h>.
11063 (timeval_to_Time): New function, for proper overflow wraparound.
11064 (term_mouse_position, term_mouse_click): Use it.
11066 * undo.c (record_first_change): Support higher-resolution time stamps
11067 in the undo buffer.
11068 (Fprimitive_undo): Use them when restoring time stamps.
11070 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
11071 (w32_get_internal_run_time):
11072 Port to higher-resolution Emacs time stamps.
11073 (ltime): Now accepts single 64-bit integer, as that's more convenient
11076 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
11078 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
11079 for compatibility with pselect. Support ns-resolution time stamps.
11081 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
11083 * xselect.c (wait_for_property_change, x_get_foreign_selection):
11084 Check for time stamp overflow, and support ns-resolution time stamps.
11086 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
11087 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
11088 (timeval_subtract): Remove; no longer needed.
11089 (XTflash, XTring_bell, x_wait_for_event):
11090 Port to ns-resolution time stamps. Don't assume time_t is signed.
11092 2012-06-22 Chong Yidong <cyd@gnu.org>

11096 2012-06-22 Eli Zaretskii <eliz@gnu.org>
11098 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
11099 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
11100 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
11101 staticidx goes up to 1597 out of 1600 = 0x640.)
11103 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
11105 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.

11117 access to `contents' member of Lisp_Vector objects with AREF and ASET
11120 2012-06-19 Chong Yidong <cyd@gnu.org>
11122 * frame.c (delete_frame): When selecting a frame on a different
11123 text terminal, do not alter the terminal's top-frame.

11126 frame's selected window and its terminal's top-frame.
11127 (unwind_format_mode_line): Restore them.
11128 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
11130 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
11131 since tty frames can be explicitly named.
11132 (prepare_menu_bars): Likewise.
11134 * term.c (Ftty_top_frame): New function.
11136 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

11139 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
11140 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
11141 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
11142 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.

11149 2012-06-18 Martin Rudalics <rudalics@gmx.at>
11151 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
11152 gets killed during executing of this function (Bug#11665).
11153 Try to always return Qt when the buffer has been actually killed.
11154 (Vkill_buffer_query_functions): In doc-string say that functions
11155 run by this hook should not change the current buffer.
11157 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
11159 Fix recently-introduced process.c problems found by static checking.
11160 * process.c (write_queue_push, write_queue_pop, send_process):
11161 Use ptrdiff_t, not int or EMACS_INT, for buffer lengths and offsets.
11162 (write_queue_pop): Fix pointer signedness problem.
11163 (send_process): Remove unused local.
11165 2012-06-17 Chong Yidong <cyd@gnu.org>

11179 * lisp.h (eassert): Assume C89 or later.
11180 This removes the need for CHECK.
11181 (CHECK): Remove. Its comments about always evaluating its
11182 argument were confusing, as 'eassert' typically does not evaluate
11185 * coding.c (produce_chars): Use ptrdiff_t, not int.
11187 * xterm.c (x_draw_underwave): Check for integer overflow.
11188 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

11361 USE_LISP_UNION_TYPE + USE_LSB_TAG cleanup (Bug#11604)
11362 * alloc.c (make_number) [!defined make_number]:
11363 Remove, as lisp.h always defines this now.

11370 USE_LSB_TAG now is always defined to be either 0 or 1.
11372 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
11373 code works fine either way, and efficiency is not a concern here,
11374 as the union type is for debugging, not for production.
11375 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
11376 Use an inline function on all platforms when using the union type,
11377 since this is simpler and 'static inline' can be used portably

11380 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
11381 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.

11483 * dispnew.c (showing_window_margins_p): Wrap in #if 0 to prevent unused
11484 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
11486 2012-06-08 Eli Zaretskii <eliz@gnu.org>
11488 * alloc.c (allocate_vectorlike): Fix last change.
11490 2012-06-08 Dmitry Antipov <dmantipov@yandex.ru>
11492 Block-based vector allocation of small vectors.

11494 adjust comment accordingly.
11495 * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'
11496 to denote vector blocks. Adjust users (live_vector_p,

11519 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
11521 * doprnt.c (doprnt): Truncate multibyte char correctly.
11522 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
11523 would mishandle a string argument "Xc" if X was a multibyte
11524 character of length 2: it would truncate after X's first byte
11525 rather than including all of X.
11527 2012-06-06 Chong Yidong <cyd@gnu.org>
11529 * buffer.c (word_wrap): Doc fix.

11576 * minibuf.c (Fassoc_string): Remove duplicate declaration.
11578 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
11579 Convert pctcpu and pctmem to Lisp float properly.
11580 Let the compiler fold better, as 100.0/0x8000 is exact.
11582 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
11584 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
11587 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
11589 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
11591 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>

11594 bitfields where appropriate, remove unused fields.
11595 * window.h (struct window): Remove unused 'last_mark_x' and
11596 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
11597 change its type from Lisp_Object to bitfield.
11598 Change type of 'force_start', 'optional_new_start',
11599 'last_had_star', 'update_mode_line' and 'start_at_line_beg'

11606 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
11607 Use 'float' consistently, rather than 'float' in most places
11608 and 'double' in a couple of places.
11610 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11612 * xdisp.c (handle_stop): Detect whether we have overlay strings
11613 loaded by testing it->current.overlay_string_index to be
11614 non-negative, instead of checking whether n_overlay_strings is
11615 positive. (Bug#11587)
11617 2012-05-31 Chong Yidong <cyd@gnu.org>
11619 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

11625 * search.c (search_buffer): Remove calls to
11626 r_alloc_inhibit_buffer_relocation, as it is now called by
11627 maybe_unify_char, which was the cause of relocation of buffer text
11630 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11632 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
11633 for the duration of call to load_charset, to avoid problems with
11634 callers of maybe_unify_char that access buffer text through C
11637 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
11638 decrement the inhibition flag, instead of just setting or
11641 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
11643 Remove obsolete '#define static' cruft.
11644 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
11645 This #undef was "temporary" in 2000; it is no longer needed
11646 now that '#define static' has gone away.
11647 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
11648 (gray_bitmap_bits): Remove; no longer needed.
11649 All uses replaced with definiens.

11661 (safe_bcopy): Remove decl; no longer has that name.
11662 (main): Coalesce #if into single bit of code, for simplicity.
11663 Cast pointers to uintptr_t, since standard libraries want integers

11692 Do not create empty overlays with the evaporate property (Bug#9642).
11693 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
11694 Bug#9642, but explicitly check that the buffer the overlay would
11695 be moved to is live and rearrange lines to make sure that errors
11696 will not put the overlay in an inconsistent state.
11697 (Fdelete_overlay): Cosmetics.
11699 2012-05-28 Eli Zaretskii <eliz@gnu.org>
11701 * w32term.c (my_bring_window_to_top): New function.

11716 This avoids undefined behavior that might cause the eassert
11717 to not catch an out-of-range value.
11719 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
11721 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

11736 Only r_alloc_inhibit_buffer_relocation needed to be added;
11737 the others were already declared.
11739 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
11740 before checking whether it's out of range. Put the check inside
11742 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.

11760 * search.c (search_buffer): Use it to inhibit relocation of buffer
11761 text while re_search_2 is doing its job, because re_search_2 is
11762 passed C pointers to buffer text. (Bug#11519)
11764 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
11765 Update value to 24.
11767 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
11768 state after an additional call to move_it_in_display_line_to, keep
11769 the values of it->max_ascent and it->max_descent found for the
11771 (pos_visible_p): Revert the comparison against bottom_y to what it
11772 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
11775 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
11777 Fix coding-related core dumps with gcc -ftrapv.
11778 The code was computing A - B, where A and B are pointers, and B is
11779 random garbage. This can lead to core dumps on platforms that
11780 have special pointer registers, and it also leads to core dumps on
11781 x86-64 when compiled with gcc -ftrapv. The fix is to compute
11782 A - B only when B is initialized properly.
11783 * coding.c (coding_set_source, coding_set_destination): Return void.
11784 (coding_change_source, coding_change_destinations): New functions,
11785 with the old behaviors of coding_set_source and coding_set_destination.
11786 All callers that need an offset changed to use these new functions.
11788 2012-05-26 Glenn Morris <rgm@gnu.org>

11803 * w32inevt.c: Include termchar.h and window.h.
11804 (do_mouse_event): Support mouse-autoselect-window. When the mouse
11805 moves, call note_mouse_highlight. If help_echo changed, call
11806 gen_help_event to produce help-echo message in the echo area.
11807 Call clear_mouse_face if mouse_face_hidden is set in the mouse
11810 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
11812 * lread.c (read1): Simplify slightly to avoid an overflow warning
11813 with GCC 4.7.0 on x86-64.
11815 2012-05-26 Eli Zaretskii <eliz@gnu.org>
11817 * bidi.c (bidi_mirror_char): Revert last change: an int is
11818 definitely wide enough here.
11820 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>

11834 Use int, not EMACS_INT, where int is wide enough.
11835 (inhibit_garbage_collection, Fgarbage_collect):
11836 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11837 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
11838 int might not be wide enough.

11856 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11857 (validate_region): Omit unnecessary test for b <= e,
11858 since that's guaranteed by the previous test.
11859 (adjust_overlays_for_delete): Avoid pos + length overflow.
11860 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
11861 (report_overlay_modification):
11862 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11863 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
11864 Omit pointer cast, which isn't needed anyway, and doesn't work
11865 after the EMACS_INT -> ptrdiff_t change.
11866 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
11867 * buffer.h: Adjust decls to match defn changes elsewhere.

11869 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11870 Use EMACS_INT, not int, where int might not be wide enough.
11871 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
11872 not int, to avoid needless 32-bit limit on 64-bit hosts.
11873 (exec_byte_code): Use tighter memory-full test, one that checks
11874 for alloca overflow. Don't compute the address of the object just
11875 before an array, as that's not portable. Use EMACS_INT, not
11876 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
11877 * callint.c (Fcall_interactively):
11878 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11879 * callproc.c (call_process_kill, Fcall_process):
11880 Don't assume pid_t fits into an Emacs fixnum.

11890 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11891 (casify_object): Avoid integer overflow when overallocating buffer.
11892 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
11893 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
11894 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
11895 * category.h (CATEGORYP): Don't assume arg is nonnegative.
11896 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
11897 integers are now checked earlier. All uses replaced with XINT.
11899 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11900 For CCL_MapSingle, check that content and value are in int range.
11901 (ccl_driver, Fregister_code_conversion_map):
11902 Check that Vcode_version_map_vector is a vector.
11903 (resolve_symbol_ccl_program): Check that vector header is in range.
11904 Always copy the vector, so that we can check its contents reliably
11905 now rather than having to recheck each instruction as it's being
11906 executed. Check that vector words fit in 'int'.
11907 (ccl_get_compiled_code, Fregister_ccl_program)
11908 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
11909 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
11910 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
11911 contents are in range.
11912 (Fccl_execute_on_string): Check that status is in range.
11913 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
11914 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
11915 Accept and return EMACS_INT, not int, because callers can pass values
11916 out of 'int' range.

11922 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11923 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
11924 avoid mishandling large integers.

11933 Remove now-unnecessary CHECK_NATNUMs.
11934 (Fdefine_charset_internal): Check ranges here, more carefully.
11935 Don't rely on undefined behavior with signed left shift overflow.
11936 Don't assume unsigned int fits into fixnum, or that fixnum fits
11937 into unsigned int. Don't require max_code to be a valid fixnum;
11938 that's not true for gb10830 4-byte on a 32-bit host. Allow
11939 invalid_code to be a cons, for the same reason. Require code_offset
11940 to be a character. Avoid int overflow if max_char is close
11942 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
11943 this is intended anyway and avoids some undefined behavior.
11944 (load_charset_map): Pass unsigned, not int, as 2nd arg of
11945 INDEX_TO_CODE_POINT, as that's what it expects.
11946 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
11947 * charset.h (DECODE_CHAR): Return int, not unsigned;
11948 this is what was intended anyway, and it avoids undefined behavior.
11949 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
11950 integer-overflow issues.
11951 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
11952 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
11953 where the argument is EMACS_INT, and this behavior is not intended.
11954 * chartab.c (Fmake_char_table, Fset_char_table_range)
11955 (uniprop_get_decoder, uniprop_get_encoder):
11956 Don't assume fixnum fits in int.
11957 * cmds.c (move_point): New function, that does the gist of
11958 Fforward_char and Fbackward_char, but does so while checking
11959 for integer overflow more accurately.
11960 (Fforward_char, Fbackward_char): Use it.
11961 (Fforward_line, Fend_of_line, internal_self_insert)
11962 (internal_self_insert):
11963 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

12744 2012-05-14 Glenn Morris <rgm@gnu.org>

12749 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
12751 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.

12754 (report_error, report_error_1, make_hdr, copy_sym)
12755 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
12756 Make arguments const char *, not char *, to avoid violations of C
12757 standard and to fix some AIX warnings reported by Gilles Pion.
12759 2012-05-14 Eli Zaretskii <eliz@gnu.org>
12761 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
12762 already have overlays loaded.
12763 (handle_single_display_spec): Before returning without displaying
12764 fringe bitmap, synchronize the bidi iterator with the main display
12765 iterator, by calling iterate_out_of_display_property.
12766 (iterate_out_of_display_property): Detect buffer iteration by
12767 testing that it->string is a Lisp string.
12768 (get_next_display_element): When the current object is exhausted,
12769 and there's something on it->stack, call set_iterator_to_next to
12770 proceed with what's on the stack, instead of returning zero.
12771 (set_iterator_to_next): If called at the end of a Lisp string,
12772 proceed to consider_string_end without incrementing string
12773 position. Don't increment display vector index past the end of
12774 the display vector. (Bug#11417)
12775 (pos_visible_p): Don't report a position visible when move_it_to
12776 stopped at the last line of window, which happens to be scanned
12777 backwards by the bidi iteration. (Bug#11464)
12779 2012-05-14 Eli Zaretskii <eliz@gnu.org>
12781 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
12782 and right-margin display specs even if the spec is invalid or we
12783 are on a TTY, and thus unable to display on the fringes.
12784 That's because the text with the property will not be displayed anyway,
12785 so we need to signal to the caller that this is a "replacing"
12786 display spec. This fixes display when the spec is invalid or we
12789 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
12791 * unexaix.c (make_hdr): Fix typo in prototype.
12792 This bug broke the build on AIX. Problem reported by Gilles Pion.

12807 2012-05-12 Glenn Morris <rgm@gnu.org>
12809 * Makefile.in (MKDIR_P): New, set by configure.
12810 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.

12826 * xgselect.c (xg_select): Put maxfds+1 into a var.
12827 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
12829 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
12831 2012-05-10 Dave Abrahams <dave@boostpro.com>
12833 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
12834 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
12836 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
12838 * dbusbind.c (xd_registered_buses): New internal Lisp object.
12839 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
12840 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
12841 Initialize xd_registered_buses.
12843 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
12845 Untag more efficiently if USE_LSB_TAG.
12846 This is based on a proposal by YAMAMOTO Mitsuharu in
12847 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
12848 For an admittedly artificial (nth 8000 longlist) benchmark on
12849 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
12850 Emacs's overall text size by 1%.
12851 * lisp.h (XUNTAG): New macro.
12852 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
12853 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
12854 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
12855 * eval.c (Fautoload):
12856 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
12857 * frame.h (XFRAME): Use XUNTAG.
12859 Port recent dbusbind.c changes to 32-bit --with-wide-int.
12860 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
12861 Remove unportable assumptions about print widths of types like
12863 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
12864 intptr_t when converting between pointer and integer, to avoid GCC
12865 warnings about wrong width.
12867 2012-05-09 Eli Zaretskii <eliz@gnu.org>
12869 * w32proc.c (new_child): Force Windows to reserve only 64KB of
12870 stack for each reader_thread, instead of defaulting to 8MB
12871 determined by the linker. This avoids failures in creating
12872 subprocesses on Windows 7, see the discussion in this thread:
12873 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
12875 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
12877 Fix up display of the *Minibuf-0* buffer in the mini window.
12878 * keyboard.c (read_char): Don't clear the echo area if there's no
12880 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
12881 contents of *Minibuf-0*) if there's no message displayed in its stead.
12883 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
12885 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
12888 2012-05-06 Chong Yidong <cyd@gnu.org>
12890 * lisp.mk (lisp): Update.
12892 2012-05-05 Jim Meyering <meyering@redhat.com>
12894 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
12896 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
12898 * data.c (PUT_ERROR): New macro.
12899 (syms_of_data): Use it. Add new error type `user-error'.
12900 * undo.c (user_error): New function.
12901 (Fprimitive_undo): Use it.
12902 * print.c (print_error_message): Adjust print style for `user-error'.
12903 * keyboard.c (user_error): New function.
12904 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
12906 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
12908 Do not limit current-time-string to years 1000..9999.
12909 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
12910 (Fcurrent_time_string): Support any year that is supported by the
12911 underlying localtime representation. Don't use asctime, as it
12912 has undefined behavior for years outside the range -999..9999.
12914 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
12916 Fix race conditions involving setenv, gmtime, localtime, asctime.
12917 Without this fix, interrupts could mess up code that uses these
12918 nonreentrant functions, since setting TZ invalidates existing
12919 tm_zone or tzname values, and since most of these functions return
12920 pointers to static storage.
12921 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
12922 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
12923 Grow the critical sections to include not just invoking
12924 localtime/gmtime, but also accessing these functions' results
12925 including their tm_zone values if any, and any related TZ setting.
12926 (format_time_string): Last arg is now struct tm *, not struct tm **,
12927 so that the struct tm is saved in the critical section.
12928 All callers changed. Simplify allocation of initial buffer, partly
12929 motivated by the fact that memory allocation needs to be outside
12930 the critical section.
12932 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
12934 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
12935 with RESET_INTERVAL.
12937 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
12938 Remove duplicated buffer name initialization.
12940 2012-05-02 Jim Meyering <jim@meyering.net>
12942 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
12944 * xfns.c (x_window): Use xstrdup (Bug#11375).
12946 2012-05-02 Eli Zaretskii <eliz@gnu.org>
12948 * xdisp.c (pos_visible_p): If already at a newline from the
12949 display string before the 'while' loop, don't walk back the glyphs
12950 from it3.glyph_row. Solves assertion violation when the display
12951 string begins with a newline (egg.el). (Bug#11367)
12953 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
12955 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
12958 2012-05-01 Glenn Morris <rgm@gnu.org>
12960 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
12961 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
12962 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
12963 All were removed before 23.1.
12965 * dispnew.c: Remove HAVE_LIBNCURSES test;
12966 it is always true on relevant platforms.
12968 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
12969 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
12971 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
12973 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
12975 * .gdbinit (xpr): Remove checks for no longer existing misc types.
12976 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
12979 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
12981 Do not avoid creating empty evaporating overlays (Bug#9642).
12982 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
12983 That is, do not delete an evaporating overlay if it becomes
12984 empty after its bounds are adjusted to fit within its buffer.
12985 This fix caused other problems, and I'm reverting it until we get
12986 to the bottom of them.
12988 2012-04-27 Chong Yidong <cyd@gnu.org>
12990 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
12992 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12994 * xdisp.c (pos_visible_p): If the window start position is beyond
12995 ZV, start the display from buffer beginning. Prevents assertion
12996 violation in init_iterator when the minibuffer window is scrolled
12997 via the scroll bar.
12999 * window.c (window_scroll_pixel_based): Likewise.
13001 2012-04-27 Chong Yidong <cyd@gnu.org>
13003 * keymap.c (where_is_internal): Doc fix (Bug#10872).
13005 2012-04-27 Glenn Morris <rgm@gnu.org>
13007 * fileio.c (Fcopy_file, Fset_file_selinux_context):
13008 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
13010 2012-04-27 Eli Zaretskii <eliz@gnu.org>
13012 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
13013 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
13015 2012-04-26 Eli Zaretskii <eliz@gnu.org>
13017 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
13018 display element, check also the underlying string or buffer
13019 character. (Bug#11341)
13021 * w32menu.c: Include w32heap.h.
13022 (add_menu_item): If the call to AppendMenuW (via
13023 unicode_append_menu) fails, disable Unicode menus only if we are
13024 running on Windows 9X/Me.
13026 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
13028 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
13029 (xgetint): Add missing shift for LSB tags.
13031 2012-04-24 Martin Rudalics <rudalics@gmx.at>
13033 * keyboard.c (read_char): Don't wipe echo area for select window
13034 events: These might get delayed via `mouse-autoselect-window'
13037 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
13039 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
13040 manipulation of :loaded-from data.
13042 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
13044 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
13045 now a cons (bug#11311).
13047 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
13049 Do not create empty overlays with the evaporate property (Bug#9642).
13050 * buffer.c (Fmove_overlay): Delete an evaporating overlay
13051 if it becomes empty after its bounds are adjusted to fit within
13052 its buffer. Without this fix, in a nonempty buffer (let ((o
13053 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
13054 yields an empty overlay that has the evaporate property, which is
13055 not supposed to happen.
13057 Fix minor GTK3 problems found by static checking.
13058 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
13059 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
13060 (struct _EmacsFixedClass, emacs_fixed_get_type):
13061 Move decls here from emacsgtkfixed.h, since they needn't be public.
13062 (emacs_fixed_get_type): Now static.
13063 (emacs_fixed_class_init): Omit unused local.
13064 (emacs_fixed_child_type): Remove; unused.
13065 * emacsgtkfixed.h (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
13066 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
13067 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
13068 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
13069 (EMACS_FIXED_GET_CLASS): Remove; unused.
13070 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
13072 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
13073 Problem reported by Juanma Barranquero for Windows -Wunused-function.
13075 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
13077 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
13078 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
13079 (__malloc_size_t, __malloc_ptrdiff_t):
13080 Remove. All uses removed, replaced by the definiens if needed,
13081 since we can assume C89 or better now.
13082 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
13083 (protect_malloc_state, align, get_contiguous_space)
13084 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)

13089 (special_realloc, _realloc_internal_nolock, _realloc_internal)
13090 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
13091 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
13092 Define using prototypes, not old style.
13093 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
13094 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
13095 (align): Don't assume that signed integer overflow wraps around.
13096 Omit unused local var.
13097 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)

13099 Omit no-longer-needed casts.
13100 (valloc): Use getpagesize, not __getpagesize.
13101 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
13102 (struct hdr): The 'magic' member is now size_t, not unsigned long.
13104 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
13106 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
13108 Move functions from C to Lisp. Make non-blocking method calls
13109 the default. Implement further D-Bus standard interfaces.

13139 (Fdbus_method_return_internal, Fdbus_method_error_internal)
13140 (Fdbus_send_signal, Fdbus_register_service)
13141 (Fdbus_register_signal, Fdbus_register_method): Move to dbus.el.

13154 * alloc.c (emacs_blocked_malloc) [GC_MALLOC_CHECK]:
13155 Do not assume ptrdiff_t is the same width as 'int'.
13157 * alloc.c: Handle unusual debugging option combinations.
13158 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
13159 since the two debugging options are incompatible.
13160 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
13162 (mem_init, mem_insert, mem_insert_fixup):
13163 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

13173 (list_system_processes, system_process_attributes) [__FreeBSD__]:
13174 Use Emacs indenting style more consistently. Avoid some casts.
13175 Use 'double' consistently rather than mixing 'float' and 'double'.
13177 2012-04-21 Eduard Wiebe <usenet@pusto.de>
13179 * sysdep.c (list_system_processes, system_process_attributes):

13189 It is never used otherwise.
13191 2012-04-20 Stefan Monnier <monnier@iro.umontreal.ca>
13193 * print.c (print_preprocess): Only check print_depth if print-circle
13195 (print_object): Check for cycles even when print-circle is nil and

13198 2012-04-20 Chong Yidong <cyd@gnu.org>
13200 * process.c (wait_reading_process_output): If EIO occurs on a pty,

13211 * xdisp.c (string_buffer_position_lim): Limit starting position to
13213 (set_cursor_from_row): If called for a mode-line or header-line
13214 row, return zero immediately.
13215 (try_cursor_movement): If inside continuation line, don't back up
13216 farther than the first row after the header line, if any.
13217 Don't consider the header-line row as "partially visible", even if
13218 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)
13220 2012-04-20 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

13236 the Emacs and Gnulib regex code is merged.
13237 (xmalloc, xrealloc): Now static.

13254 Fix minor alloc.c problems found by static checking.
13255 * alloc.c (_malloc_internal, _free_internal) [!DOUG_LEA_MALLOC]:
13256 New extern decls, to avoid calling undeclared functions.
13257 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
13258 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
13259 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
13260 (NEED_MEM_INSERT): New macro.
13261 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
13262 Remove one incorrect comment and fix another.

13276 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
13277 Remove decls. This fixes an "It stinks!".
13279 * alloc.c (which_symbols): Fix alignment issue / type clash.
13281 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
13283 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
13284 (struct Lisp_Misc_Any): Likewise.
13285 (struct Lisp_Free): Likewise.
13286 * alloc.c (union aligned_Lisp_Symbol): Define.

13296 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
13297 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
13298 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
13299 * s/netbsd.h, s/sol2-6.h:
13300 Remove definition of GC_MARK_STACK, since the default now works.
13301 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
13302 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
13303 no longer the default.
13304 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
13306 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
13308 * lread.c (lisp_file_lexically_bound_p):
13309 Fix hang at ";-*-\n" (bug#11238).
13311 2012-04-14 Eli Zaretskii <eliz@gnu.org>
13313 * xdisp.c (find_last_unchanged_at_beg_row): Don't consider a row

13325 2012-04-13 Reuben Thomas <rrt@sc3d.org>
13327 * indent.c (Fmove_to_column): Change interactive spec (Bug#739).
13329 2012-04-11 Daniel Colascione <dancol@dancol.org>
13331 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
13332 against is gone. It's better to use vfork now so that when Cygwin
13333 gains a new, working vfork, we use it automatically (bug#10398).
13335 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

13353 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
13355 * w32.c (w32_delayed_load): Record the full path of the library
13356 being loaded (bug#10424).
13358 2012-04-09 Glenn Morris <rgm@gnu.org>
13360 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
13361 not just in the obarray, before snarfing them. (Bug#11036)
13363 * Makefile.in ($(leimdir)/leim-list.el):
13364 Pass EMACS rather than BUILT_EMACS.
13366 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
13368 * process.c (make_process):
13369 * process.h: Add integer `gnutls_handshakes_tried' member to

13378 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
13379 attempts per process (connection).
13381 2012-04-09 Chong Yidong <cyd@gnu.org>
13383 * eval.c (Fuser_variable_p, user_variable_p_eh)
13384 (lisp_indirect_variable): Functions deleted.
13385 (Fdefvar): Caller changed.
13387 * callint.c (Finteractive, Fcall_interactively):
13388 * minibuf.c (Fread_variable): Callers changed.
13390 2012-04-09 Eli Zaretskii <eliz@gnu.org>
13392 * xdisp.c (set_cursor_from_row): If the display string appears in
13393 the buffer at position that is closer to point than the position
13394 after the display string, display the cursor on the first glyph of
13395 the display string. Fixes cursor display when a 'display' text
13396 property immediately follows invisible text. (Bug#11094)
13398 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
13400 composite.c: use 'double' consistently
13401 * composite.c (get_composition_id): Use 'double' consistently
13402 instead of converting 'float' to 'double' and vice versa; this is
13403 easier to understand and avoids a GCC warning.
13405 2012-04-09 Glenn Morris <rgm@gnu.org>
13407 * Makefile.in: Generate leim-list with bootstrap-emacs, in
13408 preparation for dumping it with emacs. (Bug#4789)

13429 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
13430 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
13431 (mark_memory): Mark Lisp_Objects only if pointers might hide in
13432 objects, as mark_maybe_pointer will catch them otherwise.

13447 ($(BLD)/xml.$(O)): New dependency list.
13449 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
13450 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
13451 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
13452 [!WINDOWSNT]: New macros.
13453 (init_libxml2_functions, libxml2_loaded_p): New functions.
13454 (parse_region): Call fn_xmlCheckVersion instead of using the macro
13455 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
13456 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
13457 Calls xmlCleanupParser only if libxml2 was loaded (or statically
13459 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
13460 Call init_libxml2_functions before calling libxml2 functions.
13461 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
13463 * emacs.c: Don't include libxml/parser.h.
13464 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
13465 xmlCleanupParser directly.
13467 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
13469 2012-04-07 Eli Zaretskii <eliz@gnu.org>
13471 * indent.c (Fvertical_motion): If there is a display string at
13472 point, use it.vpos to compute how many lines to backtrack after
13473 move_it_to point. (Bug#11133)
13475 2012-04-06 Eli Zaretskii <eliz@gnu.org>
13477 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
13478 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
13479 about subtle differences between FETCH_CHAR* and STRING_CHAR*
13480 macros related to unification of CJK characters. For the details,
13481 see the discussion following the message here:
13482 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
13484 2012-04-04 Chong Yidong <cyd@gnu.org>
13486 * keyboard.c (Vdelayed_warnings_list): Doc fix.
13488 2012-04-01 Eli Zaretskii <eliz@gnu.org>
13490 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA

13498 2012-03-31 Eli Zaretskii <eliz@gnu.org>
13500 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
13501 position we get to after a call to move_it_to fails the
13502 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
13503 only if we wind up in a string from display property. (Bug#11063)
13505 * window.c (Fdelete_other_windows_internal): Invalidate the row
13506 and column information about mouse highlight, so that redisplay
13507 restores it after reallocating the glyph matrices. (Bug#7464)
13509 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
13510 string comes from a `display' text property, use the buffer
13511 position of that property as if we actually saw that position in
13513 (move_it_by_lines): Remove the assertion that
13514 "it->current_x == 0 && it->hpos == 0" which can be legitimately
13515 violated when there's a before-string at the beginning of a line.
13518 2012-03-30 Eli Zaretskii <eliz@gnu.org>
13520 * xdisp.c (append_space_for_newline): If the default face was

13522 (extend_face_to_end_of_line): Use the remapped default face for
13523 extending the face to the end of the line.
13524 (display_line): Call extend_face_to_end_of_line when the default
13525 face was remapped. (Bug#11068)
13527 2012-03-29 Eli Zaretskii <eliz@gnu.org>
13529 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.

13547 * keyboard.c (Vselection_inhibit_update_commands): New variable.
13548 (command_loop_1): Use it; inhibit selection update for

13553 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
13555 2012-03-25 Kenichi Handa <handa@m17n.org>
13557 * dispextern.h (struct glyph): Change the bit length of
13558 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
13560 2012-03-24 Eli Zaretskii <eliz@gnu.org>
13562 * s/ms-w32.h (tzname): Include time.h before redirecting to

13571 !SYNC_INPUT. (Bug#11080)
13573 2012-03-23 Eli Zaretskii <eliz@gnu.org>
13575 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
13576 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
13577 when fetching a multibyte character consumes more bytes than
13578 CHAR_BYTES returns, due to unification of CJK characters in
13579 string_char. (Bug#11073)
13581 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
13583 * process.c (wait_reading_process_output): Handle pty disconnect
13584 by refraining from sending oneself a SIGCHLD (bug#10933).
13586 2012-03-22 Chong Yidong <cyd@gnu.org>
13588 * dispextern.h (struct it): New member string_from_prefix_prop_p.

13618 that is not from display property, accept the row as a "cursor
13619 row" if one of the string's character has a non-nil `cursor'
13620 property. Fixes cursor positioning when there are newlines in
13621 overlay strings, e.g. in icomplete.el. (Bug#11035)
13623 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
13625 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
13627 2012-03-12 Chong Yidong <cyd@gnu.org>
13629 * eval.c (inhibit_lisp_code): Rename from
13630 inhibit_window_configuration_change_hook; move from window.c.
13632 * xfns.c (unwind_create_frame_1, Fx_create_frame):
13633 * window.c (run_window_configuration_change_hook)
13634 (syms_of_window): Callers changed.
13636 2012-03-11 Chong Yidong <cyd@gnu.org>

13649 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
13651 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
13653 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
13654 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
13657 2012-03-03 Glenn Morris <rgm@gnu.org>
13659 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
13661 2012-03-02 Eli Zaretskii <eliz@gnu.org>

13664 position past the first glyph_row that ends at ZV. (Bug#10902)
13665 (redisplay_window, next_element_from_string): Fix typos in
13667 (redisplay_window): Pass to move_it_vertically the margin in
13668 pixels, not in screen lines.
13670 2012-03-02 Glenn Morris <rgm@gnu.org>
13672 * buffer.c (buffer-list-update-hook): Doc fix.
13674 2012-02-29 Eli Zaretskii <eliz@gnu.org>
13676 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
13677 push_it before setting up the iterator for the first overlay
13678 string, even if we have an empty string loaded.
13679 (next_overlay_string): If there's an empty string on the iterator
13680 stack, pop the stack. (Bug#10903)
13682 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
13684 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
13685 Suggested by Stefan Monnier in
13686 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
13687 * alloc.c (widen_to_Lisp_Object): New static function.
13688 (mark_memory): Also mark Lisp_Objects by fetching pointer words
13689 and widening them to Lisp_Objects. This would work even if
13690 USE_LSB_TAG is defined and wide integers are used, which might
13691 happen in a future version of Emacs.
13693 2012-02-25 Chong Yidong <cyd@gnu.org>
13695 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
13698 * xselect.c (Fx_selection_exists_p): Doc fix.

13731 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
13732 when computing $valmask.
13734 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
13735 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
13736 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
13737 It's useless in that case, and it can cause problems on hosts
13738 that allocate halves of EMACS_INT values separately.
13739 Reported by Dan Horák. Diagnosed by Andreas Schwab in
13740 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
13741 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
13742 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
13743 it avoids undefined behavior on hosts where shifting right by more
13744 than the word width has undefined behavior.

13870 * character.c (char_width): Return EMACS_INT, not int.
13871 (char_width, c_string_width): Check for overflow when

13905 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
13906 first 2 arguments are identical. This makes inserting large

14361 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
14362 verifies glyph row's hash code--we have just reallocated the

14528 is set, removing the need for VIRT_ADDRESS_VARIES.
14529 (PURE_P): Use a more-efficient implementation that needs just one

14546 behave as if the cursor position were at the window margin.
14548 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
14549 and the cursor position is out of bounds, behave as if the cursor
14550 position were at the window margin. (Bug#10075)
14552 2011-11-18 Chong Yidong <cyd@gnu.org>

14576 compute_line_metrics.
14577 (compute_line_metrics): Call row_hash, instead of computing the
14580 * dispnew.c (verify_row_hash): Call row_hash for computing the
14581 hash code of a row, instead of duplicating code from xdisp.c.
14583 * dispextern.h (row_hash): Add prototype.
14585 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
14587 * frame.c (delete_frame): Don't delete the terminal when the last

14636 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
14637 with user-defined heap size. Bump the default size of the temacs

14688 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
14690 Avoid some portability problems by eschewing 'extern inline' functions.
14691 The trivial performance wins aren't worth the portability hassles; see
14692 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
14694 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

14734 (delete_all_subwindows): Rename to delete_all_child_windows.
14735 (Fdelete_other_windows_internal, Fset_window_configuration):
14736 Call delete_all_child_windows instead of delete_all_subwindows.

14742 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
14743 This is also needed for porting to any host where GC_MARK_STACK is
14744 not GC_MAKE_GCPROS_NOOPS.
14745 (which_symbols): Use it.
14747 2011-11-07 Kenichi Handa <handa@m17n.org>

14760 * xmenu.c (cleanup_widget_value_tree): New function.
14761 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
14762 calling free_menubar_widget_value_tree directly (Bug#9830).
14764 2011-11-06 Paul Eggert <eggert@cs.ucla.edu>
14766 Fix some portability problems with 'inline'.

14768 (window_box_width, window_box_left, window_box_left_offset)
14769 (window_box_right, window_box_right_offset): Declare extern.
14770 Otherwise, these inline functions do not conform to C99 and
14771 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
14772 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
14773 * intervals.c (adjust_intervals_for_insertion)
14774 (adjust_intervals_for_deletion): Now extern, because otherwise the

14776 (static_offset_intervals): Remove.
14777 (offset_intervals): Rewrite using the old contents of
14778 static_offset_intervals. The old version didn't conform to C99
14779 because an extern inline function contained a reference to an
14780 identifier with static linkage.
14782 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
14784 * keyboard.c (interrupt_signal): Don't call kill-emacs while in

14846 official. Move initialization of image_cache_refcount and
14847 dpyinfo_refcount before calling init_frame_faces (Bug#9943).

15015 (w32font_open_internal, compute_metrics):
15016 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
15017 instead of calling the "wide" APIs directly.

15092 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
15093 * editfns.c: Rewrite current-time-zone so that it invokes
15094 the equivalent of (format-time-string "%Z") to get the time zone name.
15095 This fixes a bug when the time zone name contains characters that
15096 need converting from the system time locale to Emacs internal format.
15097 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
15098 that patch fixed format-time-string to do the conversion, but
15099 I forgot to fix current-time-zone.
15100 (format_time_string): New function, containing most of
15101 what Fformat_time_string used to contain.
15102 (Fformat_time_string): Rewrite in terms of format_time_string.
15103 This doesn't change this function's behavior.

15105 This fixes the bug reported by Michael Schierl in
15106 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
15107 Jason Rumney's 2007-06-07 change worked around this bug, but
15109 * systime.h (tzname, timezone): Remove no-longer-used declarations.
15111 2011-10-19 Eli Zaretskii <eliz@gnu.org>
15113 * xdisp.c (start_display): If the character at POS is displayed
15114 via a display vector, reset IT->current.dpvec_index to zero.
15115 (try_window_reusing_current_matrix): If a line ends in a display
15116 vector or the next line starts in a display vector, continue
15117 redrawing the window even though the character position of
15118 start_row was reached.
15121 2011-10-18 Chong Yidong <cyd@gnu.org>
15123 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
15124 with nobreak-char-display too.
15126 2011-10-18 Eli Zaretskii <eliz@gnu.org>
15128 Fix part 3 of bug#9771.
15129 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
15130 (bidi_resolve_neutral): Don't enter the expensive loop looking for
15131 non-neutral characters if the current character is a paragraph
15132 separator (a.k.a. Newline). This avoids running the same
15133 expensive loop twice, once when we consume the preceding newline
15134 and the other time when the line actually needs to be displayed.
15135 Avoid the loop when we see neutrals on the base embedding level
15136 following a character whose directionality is the same as the
15137 paragraph's. This avoids running the expensive loop when a line
15138 ends in a long sequence of neutrals, like control characters.
15139 Add assertion against STRONG_AL type. Slightly rearrange code
15140 that determines the type of a neutral given the first non-neutral
15142 (bidi_level_of_next_char): Set next_en_pos to zero when
15143 invalidating its info.
15145 2011-10-17 Eli Zaretskii <eliz@gnu.org>
15147 * xdisp.c (push_display_prop): Determine whether to record string
15148 or buffer position by IT->string, not by IT->method. Allow
15149 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
15150 (move_it_vertically_backward): Don't look for character position
15151 immediately after the newline when in a continuation line.
15154 2011-10-15 Martin Rudalics <rudalics@gmx.at>
15156 * window.c (coordinates_in_window): Rewrite and delabelize
15157 vertical border check. (Bug#5357) (Bug#9618)
15159 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
15161 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
15162 errors in XSetWindowBorder (bug#9310).
15164 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
15166 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
15167 avoid crash when xmalloc overrun checking is enabled.
15169 2011-10-13 Eli Zaretskii <eliz@gnu.org>
15171 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
15172 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
15173 cursor motion with <left> and <right> arrow keys.
15175 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
15176 some callers set that themselves.
15178 2011-10-12 Eli Zaretskii <eliz@gnu.org>
15180 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
15181 display string and the previous row comes from the same string and
15182 is empty. (Bug#9739) (Bug#9738)
15184 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
15186 * doc.c (get_doc_string): Encode file name (bug#9735).
15188 2011-10-12 Eli Zaretskii <eliz@gnu.org>
15190 * bidi.c (bidi_level_of_next_char):
15191 * xdisp.c (get_visually_first_element): Remove old incorrect
15192 comments regarding the Unicode Line Separator character.
15194 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
15196 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
15198 * alloc.c (Fgc_status): Do not access beyond zombies array
15199 boundary if nzombies > MAX_ZOMBIES.
15200 * alloc.c (dump_zombies): Add missing format specifier.
15202 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
15204 * xdisp.c (set_cursor_from_row): Simplify conditionals,
15205 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
15207 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
15208 Some packages use them to denote characters with modifiers.
15210 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
15212 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
15213 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
15214 matching a pp-number. Rename parameter var to var1.
15216 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
15218 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
15220 2011-10-08 Glenn Morris <rgm@gnu.org>
15222 * callint.c (Fcall_interactively): Give a more explicit error for the
15223 'c' case with a non-character input. (Bug#8479)
15225 2011-10-08 Eli Zaretskii <eliz@gnu.org>
15227 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
15229 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
15230 lines that are hscrolled on the left.
15232 * dispnew.c (buffer_posn_from_coords): Account for a possible
15233 presence of header-line. (Bug#4426)
15235 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
15237 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
15238 Don't advertise functionality which we discourage or doesn't work.
15240 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
15242 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
15243 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
15244 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
15245 this makes Emacs dump core during garbage collection on rare
15246 occasions. sizeof is obviously inferior to offsetof here, so
15247 stick with offsetof.
15248 (GC_POINTER_ALIGNMENT): New macro.
15249 (mark_memory): Omit 3rd (offset) arg; caller changed.
15250 Don't assume EMACS_INT alignment is the same as pointer alignment.
15252 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
15254 * keyboard.c (read_key_sequence_remapped): New var.
15255 (read_key_sequence): Compute remapping in the right buffer.
15256 (command_loop_1): Use read_key_sequence's remapping directly.
15258 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
15260 * dired.c (file_name_completion): Don't expand file name.
15261 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
15262 before checking file name handler.
15264 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
15265 they've been requested explicitly (bug#9591).
15267 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
15269 * keymap.c (Fsingle_key_description): Use make_specified_string
15270 instead of build_string to build string from push_key_description.
15273 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
15275 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
15276 This fixes a Y2038 bug on 64-bit hosts.
15277 * buffer.c (reset_buffer):
15278 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
15279 (Fclear_buffer_auto_save_failure):
15280 Use 0, not -1, to represent an unset failure time, since time_t
15281 might not be signed.
15283 Remove dependency on glibc malloc internals.
15284 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15285 Move back here from lisp.h, but with their new implementations.
15286 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15287 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
15288 * charset.c (charset_table_init): New static var.
15289 (syms_of_charset): Use it instead of xmalloc. This removes a
15290 dependency on glibc malloc internals. See Eli Zaretskii's comment in
15291 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
15292 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15293 Move back to alloc.c.
15294 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15295 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
15297 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
15299 * nsterm.m (windowDidResize): Call x_set_window_size only when
15300 ns_in_resize is true. Otherwise set pixelwidth/height and
15301 call change_frame_size (Bug#9628).
15303 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
15305 Port --enable-checking=all to Fedora 14 x86-64.
15306 * charset.c (syms_of_charset): Also account for glibc malloc's
15307 internal overhead when calculating the initial malloc maximum.
15309 Port --enable-checking=all to Fedora 14 x86.
15310 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15312 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
15313 (overrun_check_realloc, overrun_check_free):
15314 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
15315 That way, xmalloc returns a properly-aligned pointer even if
15316 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
15317 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
15318 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
15319 into account when calculating the initial malloc maximum.
15320 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15321 Move here from alloc.c, so that charset.c can use it too.
15322 Properly align; the old code wasn't right for common 32-bit hosts
15323 when configured with --enable-checking=all.
15324 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15325 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
15327 2011-09-29 Eli Zaretskii <eliz@gnu.org>
15329 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
15332 2011-09-28 Eli Zaretskii <eliz@gnu.org>
15334 * xdisp.c (compute_display_string_end): If there's no display
15335 string at CHARPOS, return -1.
15337 * bidi.c (bidi_fetch_char): When compute_display_string_end
15338 returns a negative value, treat the character as a normal
15339 character not covered by a display string. (Bug#9624)
15341 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
15343 * lread.c (Fread_from_string): Fix typo in docstring.
15345 2011-09-27 Eli Zaretskii <eliz@gnu.org>
15347 * xdisp.c (handle_invisible_prop): If invisible text ends on a
15348 newline, reseat the iterator instead of bidi-iterating there one
15349 character at a time. (Bug#9610)
15350 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
15351 TO_CHARPOS if the bidi iterator is at base embedding level.
15353 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
15355 * lread.c (readevalloop): Use correct code for NBSP.
15356 (read1): Likewise. (Bug#9608)
15358 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
15360 * dbusbind.c (Fdbus_register_signal): When service is not
15361 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
15363 2011-09-25 Glenn Morris <rgm@gnu.org>
15365 * buffer.c (truncate-lines): Doc fix.
15367 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
15369 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
15370 (Fset_window_next_buffers): Doc fix.
15372 2011-09-24 Glenn Morris <rgm@gnu.org>
15374 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
15376 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
15378 Fix minor problems found by static checking.
15379 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
15380 * indent.c (Fvertical_motion): Fix == vs = typo.
15382 2011-09-24 Eli Zaretskii <eliz@gnu.org>
15384 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
15385 Default value is now t. Doc fix.
15387 * indent.c (Fvertical_motion): Compute and apply the overshoot
15388 logic when moving up, not only when moving down. Fix the
15389 confusing name and values of the it_overshoot_expected variable;
15390 logic changes accordingly. (Bug#9254) (Bug#9549)
15392 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
15393 CHARPOS is covered by a display string which includes newlines.
15394 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
15395 is covered by a display string with embedded newlines.
15397 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
15399 * dbusbind.c (Fdbus_register_signal): Add match rule to
15400 Vdbus_registered_objects_table. (Bug#9581)
15401 (Fdbus_register_method, Vdbus_registered_objects_table):
15404 2011-09-24 Jim Meyering <meyering@redhat.com>
15406 do not ignore write error for any output size
15407 The previous change was incomplete.
15408 While it makes emacs --batch detect the vast majority of stdout
15409 write failures, errors were still ignored whenever the output size is
15410 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
15411 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
15412 && echo FAIL: ignored write error
15413 FAIL: ignored write error
15414 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
15415 && echo FAIL: ignored write error
15416 FAIL: ignored write error
15417 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
15419 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
15421 * emacs.c (Fkill_emacs): In noninteractive mode exit
15422 non-successfully if a write error occurred on stdout. (Bug#9574)
15424 2011-09-21 Eli Zaretskii <eliz@gnu.org>
15426 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
15429 * dispextern.h (struct it): Update the comment documenting what
15432 2011-09-20 Eli Zaretskii <eliz@gnu.org>
15434 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
15435 a display string, extend search for cursor position to end of row.
15436 (find_row_edges): If the row ends in a newline from a display
15437 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
15438 Handle the case of a display string with multiple newlines.
15439 (Fcurrent_bidi_paragraph_direction): Fix search for previous
15440 non-empty line. Fixes confusing cursor motion with arrow keys at
15441 the beginning of a line that starts with whitespace.
15443 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
15445 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
15448 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
15450 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
15451 boolean (Bug#9154).
15453 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15455 * xdisp.c (display_line): Record maximum and minimum buffer
15456 positions even if no glyphs were produced (e.g., by a zero-width
15457 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
15458 buffer positions that will be removed from the glyph row because
15460 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
15461 column is beyond frame width: don't subtract 1 "pixel" when
15462 computing width of the stretch.
15463 (reseat_at_next_visible_line_start): Undo the change made on
15464 2011-09-17 that saved paragraph information and restored it after
15465 the call to `reseat'. (Bug#9545)
15467 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15469 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
15470 and turn window cursor on if cleared (Bug#9415).
15472 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
15474 * search.c (boyer_moore): Take unibyte characters from pattern
15475 literally. (Bug#9458)
15477 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15479 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
15481 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
15483 Fix minor problem found by static checking.
15484 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
15485 initialized, to pacify gcc -Wuninitialized.
15487 * fileio.c: Report proper errno when syscall falls.
15488 (Finsert_file_contents): Save and restore errno,
15489 so that report_file_error outputs the correct diagnostic.
15490 (Fwrite_region) [CLASH_DETECTION]: Likewise.
15492 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15494 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
15496 2011-09-17 Eli Zaretskii <eliz@gnu.org>
15498 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
15499 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
15501 2011-09-17 Eli Zaretskii <eliz@gnu.org>
15503 * xdisp.c (reseat_at_next_visible_line_start): Keep information
15504 about the current paragraph and restore it after the call to reseat.
15506 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
15507 (bidi_find_paragraph_start): Search back for paragraph beginning
15508 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
15509 (bidi_move_to_visually_next): Only trigger paragraph-related
15510 computations when the last character is a newline or at EOB, not
15511 just any NEUTRAL_B. (Bug#9470)
15513 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
15514 truncated lines if point is covered by a display string. (Bug#9524)
15516 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
15518 * xselect.c: Relax test for outgoing X longs (Bug#9498).
15519 (cons_to_x_long): New function.
15520 (lisp_data_to_selection_data): Use it. Correct the test for
15521 short-versus-long data; it was negated. Break out of vector
15522 loop, for efficiency, when a long datum is discovered.
15524 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
15526 * eval.c (Fquote): Document its non-consing behavior (bug#9482).

15540 * editfns.c (Fformat): Correctly handle text properties on "%%".
15542 2011-09-15 Eli Zaretskii <eliz@gnu.org>
15544 * xterm.c (x_draw_composite_glyph_string_foreground):

15546 * term.c (encode_terminal_code):
15547 * composite.c (composition_update_it, get_composition_id):
15548 * xdisp.c (get_next_display_element)
15549 (fill_composite_glyph_string): Add comments about special meaning
15550 of TAB characters in a composition.
15552 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
15554 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
15555 This occurs when processing a multibyte format.
15556 Problem reported by Wolfgang Jenker.
15558 2011-09-15 Johan Bockgård <bojohan@gnu.org>
15560 * xdisp.c (try_cursor_movement): Only check for exact match if
15561 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
15563 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
15565 Remove unused external symbols.
15566 * dispextern.h (calc_pixel_width_or_height): Remove decl.
15567 * xdisp.c (calc_pixel_width_or_height): Now static.
15568 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.

15570 * w32term.c: Fix comment to match code.
15571 * xterm.c, xterm.h (x_catching_errors): Remove.
15573 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
15575 * xselect.c: Use signed conversions more consistently (Bug#9498).
15576 (selection_data_to_lisp_data): Assume incoming selection data are
15577 signed integers, not unsigned. This is to be consistent with
15578 outgoing selection data, which was modified to use signed integers
15579 in as part of the fix to Bug#9196 in response to Jan D.'s comment
15580 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
15581 expects long, not unsigned long.
15583 2011-09-14 Eli Zaretskii <eliz@gnu.org>
15585 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
15586 computation of loop end. Reported by Johan Bockgård
15589 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
15591 * frame.c (Fother_visible_frames_p): Function deleted.
15593 2011-09-12 Eli Zaretskii <eliz@gnu.org>
15595 * indent.c (compute_motion): Process display vector front to back
15596 rather than the other way around. (Bug#2496)
15598 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
15600 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
15602 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
15604 * minibuf.c (Fread_from_minibuffer): Doc fix.
15606 2011-09-11 Eli Zaretskii <eliz@gnu.org>
15608 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
15609 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
15611 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
15613 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
15614 value for non-existent files.
15616 2011-09-11 Eli Zaretskii <eliz@gnu.org>
15618 * fileio.c (Finsert_file_contents): If the file cannot be opened,
15619 set its "size" to -1. This will set the modtime_size field of
15620 the corresponding buffer to -1, which is what
15621 verify-visited-file-modtime expects for files that do not exist.
15624 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
15626 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
15628 * lisp.h: ... from here. push_key_description is no longer
15629 defined in keyboard.c, so its declaration should not be in
15630 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
15631 logically belongs with push_key_description.
15633 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
15635 * buffer.h: Include <sys/types.h> instead of <time.h>.
15636 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
15637 Problem reported by Herbert J. Skuhra.
15639 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
15641 * xml.c (parse_region): Make the parsing work for
15642 non-comment-starting XML files again (bug#9144).
15644 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
15646 * image.c (gif_load): Fix calculation of bottom and right corner.
15649 2011-09-10 Eli Zaretskii <eliz@gnu.org>
15651 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
15652 redisplay in small windows.
15654 2011-09-09 Eli Zaretskii <eliz@gnu.org>
15656 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
15658 2011-09-08 Martin Rudalics <rudalics@gmx.at>
15660 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
15661 Operate on live windows only.
15663 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
15665 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
15667 2011-09-07 Eli Zaretskii <eliz@gnu.org>
15669 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
15670 only under bidi iteration.
15672 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
15674 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
15676 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15678 isnan: Fix porting problem to Solaris 10 with bundled gcc.
15679 Without this fix, the command to link temacs failed due to an
15680 undefined symbol __builtin_isnan. This is because
15681 /usr/include/iso/math_c99.h #defines isnan(x) to
15682 __builtin_isnan(x), but the bundled gcc, which identifies itself
15683 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
15685 * floatfns.c (isnan): #undef, and then #define to a clone of
15687 (Fisnan): Always define, since it's always available now.
15688 (syms_of_floatfns): Always define isnan at the Lisp level.
15690 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15692 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
15694 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15696 * fileio.c: Fix bugs with large file offsets (Bug#9428).
15697 The previous code assumed that file offsets (off_t values) fit in
15698 EMACS_INT variables, which is not true on typical 32-bit hosts.
15699 The code messed up by falsely reporting buffer overflow in cases
15700 such as (insert-file-contents "big" nil 1 2) into an empty buffer
15701 when "big" contains more than 2**29 bytes, even though this
15702 inserts just one byte and does not overflow the buffer.
15703 (Finsert_file_contents): Store file offsets as off_t
15704 values, not as EMACS_INT values. Check for overflow when
15705 converting between EMACS_INT and off_t. When checking for
15706 buffer overflow or for overlap, take the offsets into account.
15707 Don't use EMACS_INT for small values where int suffices.
15708 When checking for overlap, fix a typo: ZV was used where
15709 ZV_BYTE was intended.
15710 (Fwrite_region): Don't assume off_t fits into 'long'.
15711 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
15713 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
15715 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
15717 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
15719 sprintf-related integer and memory overflow issues (Bug#9412).
15721 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
15722 (esprintf, exprintf, evxprintf): New functions.
15723 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
15724 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
15725 (modify_event_symbol): Do not assume that the length of
15726 name_alist_or_stem is safe to alloca and fits in int.
15727 (Fexecute_extended_command): Likewise for function name and binding.
15728 (Frecursion_depth): Wrap around reliably on integer overflow.
15729 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
15730 since some callers pass EMACS_INT values.
15731 (Fsingle_key_description): Don't crash if symbol name contains more
15732 than MAX_ALLOCA bytes.
15733 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
15734 (get_minibuffer): Arg is now EMACS_INT, not int.
15735 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
15736 (esprintf, exprintf, evxprintf): New decls.
15737 * window.h (command_loop_level, minibuf_level): Reflect API changes.
15739 * dbusbind.c (signature_cat): New function.
15740 (xd_signature, Fdbus_register_signal):
15741 Do not overrun buffer; instead, report string overflow.
15743 * dispnew.c (add_window_display_history): Don't overrun buffer.
15744 Truncate instead; this is OK since it's just a log.
15746 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
15747 even if the time zone offset is outlandishly large.
15748 Don't mishandle offset == INT_MIN.
15750 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
15751 when creating daemon; the previous buffer-overflow check was incorrect.
15753 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
15754 which has the guts of the old verror function.
15756 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
15757 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
15759 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
15760 (font_unparse_xlfd): Don't blindly alloca long strings.
15761 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
15762 fits in int, when using sprintf. Use single snprintf to count
15763 length of string rather than counting it via multiple sprintfs;
15764 that's simpler and more reliable.
15765 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
15766 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
15767 sprintf, in case result does not fit in int.
15769 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
15770 (fontset_from_font): Print it.
15772 * frame.c (tty_frame_count): Now printmax_t, not int.
15773 (make_terminal_frame, set_term_frame_name): Print it.
15774 (x_report_frame_params): In X, window IDs are unsigned long,
15775 not signed long, so print them as unsigned.
15776 (validate_x_resource_name): Check for implausibly long names,
15777 and don't assume name length fits in 'int'.
15778 (x_get_resource_string): Don't blindly alloca invocation name;
15779 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
15782 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
15783 (xg_check_special_colors, xg_set_geometry):
15784 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
15786 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
15787 Use esprintf, not sprintf, in case result does not fit in int.
15789 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
15790 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
15791 it as a large positive number.
15792 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
15793 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
15795 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
15796 in case result does not fit in int.
15798 * print.c (float_to_string): Detect width overflow more reliably.
15799 (print_object): Make sprintf buffer a bit bigger, to avoid potential
15800 buffer overrun. Don't assume list length fits in 'int'. Treat
15801 print length of 0 as 0, not as infinity; to be consistent with other
15802 uses of print length in this function. Don't overflow print length
15803 index. Don't assume hash table size fits in 'long', or that
15804 vectorlike size fits in 'unsigned long'.
15806 * process.c (make_process): Use printmax_t, not int, to format
15807 process-name gensyms.
15809 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
15811 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
15812 to avoid potential buffer overrun.
15814 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
15815 if X resource line is longer than 512 bytes.
15817 * xfns.c (x_window): Make sprintf buffer a bit bigger
15818 to avoid potential buffer overrun.
15820 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
15822 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
15824 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
15826 Integer overflow fixes for scrolling, etc.
15827 Without these, Emacs silently mishandles large integers sometimes.
15828 For example, "C-u 4294967297 M-x recenter" was treated as if
15829 it were "C-u 1 M-x recenter" on a typical 64-bit host.
15831 * xdisp.c (try_window_id): Check Emacs fixnum range before
15832 converting to 'int'.
15834 * window.c (window_scroll_line_based, Frecenter):
15835 Check that an Emacs fixnum is in range before assigning it to 'int'.
15836 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
15837 values converted from Emacs fixnums.
15838 (Frecenter): Don't wrap around a line count if it is out of 'int'
15839 range; instead, treat it as an extreme value.
15840 (Fset_window_configuration, compare_window_configurations):
15841 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
15843 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
15844 that can exceed INT_MAX. Check that EMACS_INT value is in range
15845 before assigning it to the (possibly-narrower) index.
15846 (match_limit): Don't assume that a fixnum can fit in 'int'.
15848 * print.c (print_object): Use ptrdiff_t, not int, for index that can
15851 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
15852 (Fvertical_motion): Don't wrap around LINES values that don't fit
15853 in 'int'. Instead, treat them as extreme values. This is good
15854 enough for windows, which can't have more than INT_MAX lines anyway.
15856 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
15858 * Require libxml/parser.h to avoid compilation warning.
15860 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
15862 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
15863 since this reportedly can destroy thread storage.
15865 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
15867 * syntax.c (find_defun_start): Update all cache variables if
15868 exiting early (Bug#9401).
15870 2011-08-30 Eli Zaretskii <eliz@gnu.org>
15872 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
15874 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
15875 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
15876 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
15878 * term.c (tty_append_glyph): New function.
15879 (produce_stretch_glyph): Static function and its prototype deleted.
15881 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
15884 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
15886 * image.c (parse_image_spec): Check for nonnegative, not for positive,
15887 when checking :margin (Bug#9390).
15888 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
15889 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
15890 so that the name doesn't mislead. All uses changed.
15892 2011-08-28 Johan Bockgård <bojohan@gnu.org>
15894 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
15897 2011-08-27 Eli Zaretskii <eliz@gnu.org>
15899 * xdisp.c (move_it_to): Don't bail out early when reaching
15900 position beyond to_charpos, if we are scanning backwards.
15901 (move_it_vertically_backward): When DY == 0, make sure we get to
15902 the first character in the line after the newline.
15904 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
15906 * ccl.c: Improve and simplify overflow checking (Bug#9196).
15907 (ccl_driver): Do not generate an out-of-range pointer.
15908 (Fccl_execute_on_string): Remove unnecessary check for
15909 integer overflow, noted by Stefan Monnier in
15910 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
15911 Remove a FIXME that didn't need fixing.
15912 Simplify the newly-introduced buffer reallocation code.
15914 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
15916 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
15918 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
15920 Integer and memory overflow issues (Bug#9196).
15922 * doc.c (get_doc_string): Rework so that
15923 get_doc_string_buffer_size is the actual buffer size, rather than
15924 being 1 less than the actual buffer size; this makes xpalloc more
15927 * image.c (x_allocate_bitmap_record, cache_image):
15928 * xselect.c (Fx_register_dnd_atom):
15929 Simplify previous changes by using xpalloc.
15931 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
15932 since either will do and ptrdiff_t is convenient with xpalloc.
15934 * charset.c (charset_table_size)
15935 (struct charset_sort_data.priority): Now ptrdiff_t.
15936 (charset_compare): Don't overflow if priorities differ greatly.
15937 (Fsort_charsets): Don't assume list length fits in int.
15938 Check for size-calculation overflow when allocating sort data.
15939 (syms_of_charset): Allocate an initial charset table that is
15940 just under 64 KiB, to avoid problems with glibc malloc and mmap.
15942 * cmds.c (internal_self_insert): Check for size-calculation overflow.
15944 * composite.h (struct composition.glyph_len): Now int, not unsigned.
15945 The actual value is always <= INT_MAX, and leaving it unsigned made
15946 overflow checking harder.
15948 * dispextern.h (struct glyph_matrix.rows_allocated)
15949 (struct face_cache.size): Now ptrdiff_t, for convenience in use
15950 with xpalloc. The values are still always <= INT_MAX.
15952 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
15954 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
15955 (SAFE_NALLOCA): New macro.
15957 * region-cache.c (struct boundary.pos, find_cache_boundary)
15958 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
15959 (set_cache_region, invalidate_region_cache)
15960 (revalidate_region_cache, know_region_cache, region_cache_forward)
15961 (region_cache_backward, pp_cache):
15962 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
15963 so that ptrdiff_t * can be passed to xpalloc.
15964 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
15965 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
15966 (pp_cache): Don't assume cache_len fits in int.
15967 * region-cache.h: Adjust extern decls to match.
15969 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
15970 EMACS_INT, since either will do, for xpalloc.
15972 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
15973 (xnmalloc, xnrealloc, xpalloc): New functions.
15975 * bidi.c (bidi_shelve_header_size): New constant.
15976 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
15977 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
15979 * bidi.c (bidi_cache_shrink):
15980 * buffer.c (overlays_at, overlays_in, record_overlay_string)
15982 Don't update size of array until after memory allocation succeeds,
15983 because xmalloc/xrealloc may not return.
15984 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
15985 now that we have proper integer overflow checking.
15986 (record_overlay_string, overlay_strings): Catch overflows when
15987 calculating size of overlay_str_buf.
15989 * callproc.c (Fcall_process): Check for size overflow when
15990 calculating size of args2.
15991 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
15992 Normally we prefer signed values, but sticking with ptrdiff_t would
15993 require adding more-complicated checks.
15995 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
15996 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
15997 Redo buffer-overflow calculations to avoid integer overflow.
15998 Add a FIXME comment where memory seems to be over-allocated.
16000 * character.c (Fstring): Check for size-calculation overflow.
16002 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
16003 unnecessary integer overflow. Check for size overflow.
16004 (encode_coding_object): Don't update size until xmalloc succeeds.
16006 * composite.c (get_composition_id): Check for overflow in glyph
16007 length calculations.
16009 Integer and memory overflow fixes for display code.
16010 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
16011 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
16012 (scrolling_window): Check for overflow in size calculations.
16013 (line_draw_cost, realloc_glyph_pool, add_row_entry):
16014 Don't assume glyph table len fits in int.
16015 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
16016 (row_table_size): Now ptrdiff_t, not int.
16017 (scrolling_window): Avoid overflow in size calculations.
16018 Don't update size until allocation succeeds.
16019 * fns.c (concat): Check for overflow in size calculations.
16020 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
16021 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
16022 (NEXT_ALMOST_PRIME_LIMIT): New constant.
16024 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
16025 (get_doc_string): Check for size calculation overflow.
16026 Don't update size until allocation succeeds.

16036 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
16038 * emacs.c (main): Do not reallocate argv, since there is a null at
16039 the end that can be overwritten, and this way there's no need to
16040 worry about size-calculation overflow.
16041 (sort_args): Check for size-calculation overflow.
16043 * eval.c (init_eval_once, grow_specpdl): Don't update size until

16050 (x_set_alpha): Do not assume XINT fits in int.
16052 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
16053 This is for the members text_lines, text_cols, total_lines, total_cols,
16054 where the system imposes an 'int' limit.

16063 Check for size-calculation overflow.
16064 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
16065 do, as we prefer signed integers.

16121 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
16122 for command line length. Do not attempt to address one before the
16123 beginning of an array, as that's not portable.

16153 Check for size calculation overflow.
16154 (cache_face): Treat size calculation overflows as if they were
16155 memory exhaustion (the usual treatment), rather than aborting.
16157 * xfns.c (x_encode_text, x_set_name_internal)
16158 (Fx_change_window_property): Use ptrdiff_t, not int, to count
16159 sizes, since they can exceed INT_MAX in size. Check for size

16163 (xg_select): Check for size calculation overflow.
16164 Don't update size until alloc done.
16166 * xrdb.c (get_environ_db): Don't assume path length fits in int,
16167 as sprintf is limited to int lengths.
16169 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
16170 (X_LONG_MIN): New macros.
16171 Use them to make the following changes clearer.
16172 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
16173 This change doesn't affect the value now, but it may help remind
16174 future maintainers not to raise the value too much later.
16175 (SELECTION_QUANTUM): Remove, replacing with ...
16176 (selection_quantum): ... new function, which avoids overflow.
16178 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
16179 assumption that selection length fits in 'int'.
16180 (x_reply_selection_request, x_handle_selection_request)
16181 (x_get_window_property, receive_incremental_selection)

16196 Don't store size until memory allocation succeeds.
16197 (x_get_window_property): Plug memory leak on memory exhaustion.
16198 Don't double-block input; malloc is safe here. Don't assume 2**34
16199 - 4 fits in unsigned long. Add an xassert to check
16200 XGetWindowProperty overflow. Be more careful about overflow
16201 calculations, and distinguish size from memory overflow better.
16202 (receive_incremental_selection): When tracing, don't assume
16203 unsigned int is less than INT_MAX.
16204 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory

16207 in the range -65535 through -1 fit in an X unsigned short.
16208 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
16209 result parameters unless successful. Rely on cons_to_unsigned
16210 to report problems with elements; the old code wasn't right anyway.
16211 (x_check_property_data): Check for int overflow; we cannot use
16212 a wider type due to X limits.

16245 * lisp.h (hash_lookup, hash_put):
16246 * minibuf.c (Ftest_completion):
16247 Use ptrdiff_t for hash table indexes, not int (which is too
16248 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
16249 32-bit --with-wide-int hosts).
16251 * charset.c (Fdefine_charset_internal): Check for integer overflow.
16252 Add a FIXME comment about memory leaks.

16260 with outlandish widths.
16261 * character.h (sanitize_tab_width): Rename from sanitize_width,
16262 now that we have two such functions. All uses changed.

16280 * xterm.c: Don't go over XClientMessageEvent limit.
16281 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
16282 (x_send_scroll_bar_event): Likewise. Check that the size does not
16283 exceed limits imposed by XClientMessageEvent, as well as the usual
16284 ptrdiff_t and size_t limits.

16287 (make_lispy_movement): Use same integer type in forward decl
16288 that is used in the definition.
16289 (read_key_sequence, keyremap_step):
16290 Change bufsize argument back to int, undoing my 2011-03-30 change.
16291 We prefer signed types, and int is wide enough here.
16292 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
16293 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
16294 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
16295 length, not size_t. Use ptrdiff_t for index, not int.
16296 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
16297 possibility of integer overflow.

16325 Prefer int to unsigned where either will do.
16326 (tiff_handler): New function, combining the cores of the
16327 old tiff_error_handler and tiff_warning_handler.
16328 This function is rewritten to use vsnprintf and thereby avoid
16329 stack buffer overflows. It uses only the features of vsnprintf
16330 that are common to both POSIX and native Microsoft.
16331 (tiff_error_handler, tiff_warning_handler): Use it.
16332 (tiff_load, gif_load, imagemagick_load_image):
16333 Don't assume :index value fits in 'int'.
16334 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
16335 (imagemagick_load_image): Check that crop parameters fit into
16336 the integer types that MagickCropImage accepts. Don't assume
16337 Vimagemagick_render_type has a nonnegative value. Don't assume
16338 size_t fits in 'long'.
16339 (gs_load): Use printmax_t to print the widest integers possible.

16352 handle_single_display_spec, not just 1 or zero.
16353 (handle_single_display_spec): If the display spec is of the form
16354 `(space ...)', and specifies display in the text area, return 2
16356 (try_cursor_movement): Check for the need to scroll more
16357 accurately, and prefer exact match for point under bidi.
16358 Don't advance `row' beyond the last row of the window.

16376 buffers, return left-to-right.
16377 (set_cursor_from_row): Consider candidate row a win if its glyph

16379 positioning on the newline at EOL of R2L text within L2R
16380 paragraph, and vice versa.
16381 (try_cursor_movement): Check continued rows, in addition to
16382 continuation rows. Fixes unwarranted scroll when point enters a
16383 continued line of R2L text within an L2R paragraph, or vice versa.
16384 (cursor_row_p): Consider the case of point being equal to
16385 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
16386 from the end of a short line to the beginning of a continued line
16387 of R2L text within L2R paragraph.

16411 * xdisp.c (redisplay_window): When computing centering_position,
16412 account for the height of the header line. (Bug#8874)
16414 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
16415 instead of CHAR_TO_BYTE. Fixes a crash when a completion
16416 candidate is selected by the mouse, and that candidate has a
16417 composed character under the mouse.
16419 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
16420 coordinates reported by pos-visible-in-window-p for a composed
16421 character in column zero.
16423 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>

16427 2011-08-22 Eli Zaretskii <eliz@gnu.org>
16429 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
16430 consider it a hit if to_charpos is anywhere in the range of the
16431 composed buffer positions.
16433 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
16435 * image.c (gif_load): Don't assume that each subimage has the same
16436 dimensions as the base image. Handle disposal method that is
16437 "undefined" by the gif spec (Bug#9335).
16439 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
16441 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

16446 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
16447 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
16448 from an Org mode buffer to a Speedbar frame.

16453 with a composed character.
16455 2011-08-18 Eli Zaretskii <eliz@gnu.org>
16457 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
16458 character bidirectional type, use STRONG_L instead. Fixes crashes
16459 in a buffer produced by `describe-categories'.
16461 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
16462 members before the level stack, so they would be saved and
16463 restored when copying iterator state. Fixes incorrect reordering
16464 around TABs covered by display properties.
16466 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
16468 * process.c (Fnetwork_interface_list): Correctly determine buffer size.
16470 2011-08-17 Chong Yidong <cyd@stupidchicken.com>
16472 * eval.c (internal_condition_case, internal_condition_case_1)
16473 (internal_condition_case_2, internal_condition_case_n):
16474 Remove unnecessary aborts (Bug#9081).
16476 2011-08-17 Eli Zaretskii <eliz@gnu.org>
16478 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
16479 has no `load' handler, try opening the file locally. (Bug#9311)
16481 2011-08-16 Ken Brown <kbrown@cornell.edu>
16483 * gmalloc.c: Expand comment.
16485 2011-08-16 Eli Zaretskii <eliz@gnu.org>
16487 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
16488 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.
16490 2011-08-16 Ken Brown <kbrown@cornell.edu>
16492 Fix memory allocation problems in Cygwin build (Bug#9273).
16494 * unexcw.c ( __malloc_initialized): Declare external variable.

16499 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the
16501 (_free_internal_nolock) [CYGWIN]: Ignore requests to free storage
16502 in the static heap.
16503 [CYGWIN] (special_realloc): New function.
16504 (_realloc_internal_nolock) [CYGWIN]: Use the new function on
16505 requests to realloc storage in the static heap.
16507 2011-08-15 Paul Eggert <eggert@cs.ucla.edu>
16509 * bidi.c (bidi_initialize): Remove unused local.

16516 * deps.mk (bidi.o): Remove biditype.h and bidimirror.h.
16518 * dispextern.h: Fix a typo in the comment to bidi_type_t.
16520 * chartab.c: Improve commentary for the uniprop_table API.
16522 * bidi.c (bidi_paragraph_init): Support zero value of
16523 bidi_ignore_explicit_marks_for_paragraph_level.
16524 (bidi_initialize): Use uniprop_table instead of including
16525 biditype.h and bidimirror.h.
16527 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
16528 coordinates of the iterator when restoring from ppos_it.
16531 2011-08-14 Kenichi Handa <handa@m17n.org>
16533 * process.c (create_process): Call setup_process_coding_systems
16534 after the pid of the process is set to -1 (Bug#8162).
16536 2011-08-14 Eli Zaretskii <eliz@gnu.org>
16538 * xdisp.c (move_it_in_display_line_to): Don't invoke
16539 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
16540 ppos_it. Fixes vertical cursor motion when line beginning is
16541 covered by an image. (Bug#9296)
16543 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
16545 * nsterm.h (ns_run_ascript): Declare.
16546 (NSAPP_DATA2_RUNASSCRIPT): Define.
16548 * nsfns.m (as_script, as_result, as_status): New static variables.
16549 (ns_run_ascript): New function.
16550 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
16551 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
16552 the event loop. Get status from as_status (Bug#7276).
16554 * nsterm.m (sendEvent): If event is NSApplicationDefined and
16555 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
16556 the event loop (Bug#7276).
16558 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
16560 * gnutls.c (QCgnutls_bootprop_priority)
16561 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
16562 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
16563 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
16564 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
16565 (QCgnutls_bootprop_verify_hostname_error)
16566 (QCgnutls_bootprop_callbacks_verify): Rename from
16567 Qgnutls_bootprop_..., all uses changed.
16569 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
16572 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
16574 * xfaces.c (Qframe_set_background_mode): Now static.
16575 * dispextern.h (Qframe_set_background_mode): Remove decl.

16579 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
16581 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
16582 (Fnetwork_interface_list): Allocate in increments of bytes instead
16583 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
16584 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
16586 (struct ifflag_def): notrailers is smart on OSX.
16587 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
16588 Get hardware address with getifaddrs if available.
16590 2011-08-12 Eli Zaretskii <eliz@gnu.org>
16592 * xdisp.c (iterate_out_of_display_property): xassert that
16593 IT->position is set to within IT->object's boundaries. Break from
16594 the loop as soon as EOB is reached; avoids infloops in redisplay
16595 when IT->position is set up wrongly due to some bug.
16596 Set IT->current to match the bidi iterator unconditionally.
16597 (push_display_prop): Allow GET_FROM_STRING as IT->method on
16598 entry. Force push_it to save on the stack the current
16599 buffer/string position, to be restored by pop_it. Fix flags in
16600 the iterator structure wrt the object coming from a display
16601 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
16602 properties. (Bug#9284)
16604 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
16606 * fontset.c (fontset_get_font_group): Add proper type checks.
16609 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16611 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
16612 and LC_VERSION_MIN_MACOSX.
16613 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
16614 (dump_it) [LC_FUNCTION_STARTS]: Use it.
16616 2011-08-08 Eli Zaretskii <eliz@gnu.org>
16618 * xdisp.c (forward_to_next_line_start): Allow to use the
16619 no-display-properties-and-no-overlays under bidi display.
16620 Set disp_pos in the bidi iterator to avoid searches for display
16621 properties and overlays.
16623 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
16625 * editfns.c (Fset_time_zone_rule): Document relationship with the

16629 the font entity extracted from the cache (Bug#8109).
16631 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
16633 * composite.c (autocmp_chars): Don't reset point. That is done by
16634 restore_point_unwind (Bug#5984).
16636 2011-08-07 Juri Linkov <juri@jurta.org>
16638 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
16639 to show the arg `TIME' instead of `TIMEVAL'.
16641 2011-08-06 Eli Zaretskii <eliz@gnu.org>
16643 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
16644 display property strides EOL and includes a newline, as in
16645 longlines-mode. (Bug#9254)
16646 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
16647 word-wrap under bidirectional display. (Bug#9224)
16649 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
16650 is non-zero, even if the data buffer is NULL. Fixes a crash in
16651 vertical-motion with longlines-mode. (Bug#9254)
16653 2011-08-05 Eli Zaretskii <eliz@gnu.org>
16655 * bidi.c <bidi_cache_total_alloc>: Now static.
16656 (bidi_initialize): Initialize bidi_cache_total_alloc.
16658 * xdisp.c (display_line): Release buffer allocated for shelved bidi
16661 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
16662 amount allocated this far in `bidi_cache_total_alloc'.
16663 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
16664 non-zero, only free the data buffer without restoring the cache
16665 contents. All callers changed.
16667 * dispextern.h (bidi_unshelve_cache): Update prototype.
16669 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
16670 (move_it_in_display_line, move_it_to)
16671 (move_it_vertically_backward, move_it_by_lines): Replace the call
16672 to xfree to an equivalent call to bidi_unshelve_cache.
16673 (move_it_in_display_line_to): Fix logic of returning
16674 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
16676 2011-08-05 Eli Zaretskii <eliz@gnu.org>
16678 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
16679 came from a string character with a `cursor' property. (Bug#9229)
16681 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
16683 * Makefile.in (LIB_PTHREAD): New variable.
16684 (LIBES): Add LIB_PTHREAD (Bug#9216).
16686 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
16687 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
16689 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
16691 * regex.c (re_iswctype): Remove some redundant boolean conversions.
16693 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
16695 * xterm.c (x_find_topmost_parent): New function.
16696 (x_set_frame_alpha): Find topmost parent window with
16697 x_find_topmost_parent and set the property there also (bug#9181).
16698 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
16700 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
16702 * callproc.c (Fcall_process): Avoid vfork clobbering
16703 the local vars buffer, coding_systems, current_dir.
16705 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
16707 * keymap.c (Fmake_composed_keymap): Move to subr.el.
16709 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
16711 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
16712 so that it is not optimized away.
16714 * xdisp.c (compute_display_string_pos): Remove unused local.
16716 2011-08-02 Eli Zaretskii <eliz@gnu.org>
16718 Fix slow cursor motion and scrolling in large buffers with
16719 selective display, like Org Mode buffers. (Bug#9218)
16721 * dispextern.h (struct bidi_it): New member disp_prop_p.
16723 * xdisp.c: Remove one-slot cache of display string positions.
16724 (compute_display_string_pos): Accept an additional argument
16725 DISP_PROP_P; callers changed. Scan at most 5K characters forward
16726 for a display string or property. If found, set DISP_PROP_P
16729 * bidi.c (bidi_fetch_char): Accept an additional argument
16730 DISP_PROP_P, and pass it to compute_display_string_pos.
16731 Only handle text covered by a display string if DISP_PROP_P is returned
16732 non-zero. All callers of bidi_fetch_char changed.
16734 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
16736 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
16738 2010-12-03 Don March <don@ohspite.net>
16740 * keymap.c (Fdefine_key): Fix non-prefix key error message when
16741 last character M-[char] is translated to ESC [char] (bug#7541).
16743 2011-08-02 Kenichi Handa <handa@m17n.org>
16745 * lisp.h (uniprop_table): Extern it.
16747 * chartab.c (uniprop_table): Make it non-static.
16749 2011-08-01 Eli Zaretskii <eliz@gnu.org>
16751 * xdisp.c (forward_to_next_line_start): Accept additional argument
16752 BIDI_IT_PREV, and store into it the state of the bidi iterator had
16754 (reseat_at_next_visible_line_start): Use the bidi iterator state
16755 returned by forward_to_next_line_start to restore the state of
16756 it->bidi_it after backing up to previous newline. (Bug#9212)
16758 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
16760 * regex.c (re_comp): Protoize.
16761 (re_exec): Fix return type.
16762 (regexec): Fix type of `ret'. (Bug#9203)
16764 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16766 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
16767 This is needed if max-image-size is a floating-point number.
16769 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
16771 * print.c (print_object): Print empty symbol as ##.
16773 * lread.c (read1): Read ## as empty symbol.
16775 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
16777 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
16778 setting frame foreground color (Bug#9175).
16779 (x_set_background_color): Likewise.
16781 * nsmenu.m (-setText): Size tooltip dimensions precisely to
16782 contents (Bug#9176).
16783 (EmacsTooltip -init): Remove bezels and add shadows to
16786 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
16787 or scroll bar (Bug#8470).
16789 * nsfont.m (nsfont_open): Remove assignment to voffset and
16790 unnecessary vars hshink, expand, hd, full_height, min_height.
16791 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
16793 * nsterm.h (nsfont_info): Remove voffset field.
16795 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
16797 Implement strike-through and overline on NextStep (Bug#8863).
16799 * nsfont.m (nsfont_open): Use underline position provided by font,
16800 instead of hard-coded value of 2.
16801 (nsfont_draw): Call ns_draw_text_decoration instead.
16803 * nsterm.h: Add declaration for ns_draw_text_decoration.
16805 * nsterm.m (ns_draw_text_decoration): New function for drawing
16806 underline, overline, and strike-through.
16807 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
16808 ns_draw_text_decoration. Change treatment of cursor drawing to
16809 accommodate underlining, etc.
16811 2011-07-28 Eli Zaretskii <eliz@gnu.org>
16813 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
16816 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16818 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
16819 Without this fix, if a signal arrives just after memory fills up,
16820 'malloc' might be invoked reentrantly.
16822 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
16823 In other words, assume that every image size is allowed, on non-X
16824 hosts. This assumption is probably wrong, but it lets Emacs compile.
16826 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
16828 * regex.c (re_iswctype): Convert return values to boolean.
16830 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
16832 * xdisp.c (compute_display_string_pos): Don't use cached display
16833 string position if the buffer had its restriction changed.
16836 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16838 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
16840 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16842 Integer signedness and overflow and related fixes. (Bug#9079)
16844 * bidi.c: Integer size and overflow fixes.
16845 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
16846 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
16847 (bidi_cache_find_level_change, bidi_cache_ensure_space)
16848 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
16849 (bidi_find_other_level_edge):
16850 Use ptrdiff_t instead of EMACS_INT where either will do.
16851 This works better on 32-bit hosts configured --with-wide-int.
16852 (bidi_cache_ensure_space): Check for size-calculation overflow.
16853 Use % rather than repeated addition, for better worst-case speed.
16854 Don't set bidi_cache_size until after xrealloc returns, because it
16856 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
16857 (bidi_cache_ensure_space): Also check that the bidi cache size
16858 does not exceed that of the largest Lisp string or buffer. See Eli
16859 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
16861 * alloc.c (__malloc_size_t): Remove.
16862 All uses replaced by size_t. See Andreas Schwab's note
16863 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
16865 * image.c: Improve checking for integer overflow.
16866 (check_image_size): Assume that f is nonnull, since
16867 it is always nonnull in practice. This is one less thing to
16868 worry about when checking for integer overflow later.
16869 (x_check_image_size): New function, which checks for integer
16870 overflow issues inside X.
16871 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
16872 This removes the need for a memory_full check.
16873 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
16874 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
16875 (xbm_read_bitmap_data): Change locals back to 'int', since
16876 their values must fit in 'int'.
16877 (xpm_load_image, png_load, tiff_load):
16878 Invoke x_create_x_image_and_pixmap earlier,
16879 to avoid much needless work if the image is too large.
16880 (tiff_load): Treat overly large images as if
16881 x_create_x_image_and_pixmap failed, not as malloc failures.
16882 (gs_load): Use x_check_image_size.
16884 * gtkutil.c: Omit integer casts.
16885 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
16886 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
16888 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
16890 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
16891 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
16892 would wrongly return t on a 64-bit host.
16894 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
16895 The plain *_OVERFLOW macros run afoul of GCC bug 49705
16896 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
16897 and therefore cause GCC to emit a bogus diagnostic in some cases.
16899 * image.c: Integer signedness and overflow and related fixes.
16900 This is not an exhaustive set of fixes, but it's time to
16901 record what I've got.
16902 (lookup_pixel_color, check_image_size): Remove redundant decls.
16903 (check_image_size): Don't assume that arbitrary EMACS_INT values
16904 fit in 'int', or that arbitrary 'double' values fit in 'int'.
16905 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
16906 (tiff_load, imagemagick_load_image):
16907 Check for overflow in size calculations.
16908 (x_create_x_image_and_pixmap): Remove unnecessary test for
16909 xmalloc returning NULL; that can't happen.
16910 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
16911 (xpm_color_bucket): Use better integer hashing function.
16912 (xpm_cache_color): Don't possibly over-allocate memory.
16913 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
16914 (gif_memory_source):
16915 Use ptrdiff_t, not int or size_t, to record sizes.
16916 (png_load): Don't assume values greater than 2**31 fit in 'int'.
16917 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
16918 either works, as we prefer signed integers.
16919 (tiff_read_from_memory, tiff_write_from_memory):
16920 Return tsize_t, not size_t, since that's what the TIFF API wants.
16921 (tiff_read_from_memory): Don't fail simply because the read would
16922 go past EOF; instead, return a short read.
16923 (tiff_load): Omit no-longer-needed casts.
16924 (Fimagemagick_types): Don't assume size fits into 'int'.
16926 Improve hashing quality when configured --with-wide-int.
16927 * fns.c (hash_string): New function, taken from sxhash_string.
16928 Do not discard information about ASCII character case; this
16929 discarding is no longer needed.
16930 (sxhash-string): Use it. Change sig to match it. Caller changed.
16931 * lisp.h: Declare it.
16932 * lread.c (hash_string): Remove, since we now use fns.c's version.
16933 The fns.c version returns a wider integer if --with-wide-int is
16934 specified, so this should help the quality of the hashing a bit.
16936 * emacs.c: Integer overflow minor fix.
16937 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
16938 Define only if GNU_LINUX.
16939 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
16941 * dispnew.c: Integer signedness and overflow fixes.
16942 Remove unnecessary forward decls, that were a maintenance hassle.
16943 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
16945 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
16946 (scrolling_window): Use ptrdiff_t, not int, for byte count.
16947 (prepare_desired_row, line_draw_cost):
16948 Use int, not unsigned, where either works.
16949 (save_current_matrix, restore_current_matrix):
16950 Use ptrdiff_t, not size_t, where either works.
16951 (init_display): Check for overflow more accurately, and without
16952 relying on undefined behavior.
16954 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
16955 Remove, replacing with the new symbols in lisp.h. All uses changed.
16956 * fileio.c (make_temp_name):
16957 * filelock.c (lock_file_1, lock_file):
16958 * xdisp.c (message_dolog):
16959 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
16960 Use pMd etc. instead.
16961 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
16962 replacing the pWIDE etc. symbols removed from editfns.c.
16964 * keyboard.h (num_input_events): Now uintmax_t.
16965 This is (very slightly) less likely to mess up due to wraparound.
16968 * buffer.c: Integer signedness fixes.
16969 (alloc_buffer_text, enlarge_buffer_text):
16970 Use ptrdiff_t rather than size_t when either will do, as we prefer
16973 * alloc.c: Integer signedness and overflow fixes.
16974 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
16975 (__malloc_size_t): Default to size_t, not to int.
16976 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
16977 (Fgarbage_collect, mark_object_loop_halt, mark_object):
16978 Prefer ptrdiff_t to size_t when either would do, as we prefer
16980 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
16981 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
16982 Now const. Initialize with values that are in range even if char
16984 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
16985 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
16986 These functions do the right thing with sizes > 2**32.
16987 (check_depth): Now ptrdiff_t, not int.
16988 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
16989 Adjust to new way of storing sizes. Check for size overflow bugs
16991 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
16992 slightly wrong anyway, as it missed one instance of
16993 XMALLOC_OVERRUN_CHECK_OVERHEAD.
16994 (refill_memory_reserve): Omit needless cast to size_t.
16995 (mark_object_loop_halt): Mark as externally visible.
16997 * xselect.c: Integer signedness and overflow fixes.
16998 (Fx_register_dnd_atom, x_handle_dnd_message):
16999 Use ptrdiff_t, not size_t, since we prefer signed.
17000 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
17001 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
17002 x_dnd_atoms_size and x_dnd_atoms_length.
17004 * doprnt.c: Prefer signed to unsigned when either works.
17006 * doprnt.c (doprnt):
17008 * xdisp.c (vmessage):
17009 Use ptrdiff_t, not size_t, when using or implementing doprnt,
17010 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
17011 prefer signed arithmetic to avoid comparison confusion.
17012 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
17013 but is a bit tricky.
17015 Assume freestanding C89 headers, string.h, stdlib.h.
17016 * data.c, doprnt.c, floatfns.c, print.c:
17017 Include float.h unconditionally.
17018 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
17019 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
17020 * regex.c: Likewise for stddef.h, string.h.
17021 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
17022 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
17023 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
17024 (STDC_HEADERS): Remove obsolete defines.
17025 * sysdep.c: Include limits.h unconditionally.
17027 Assume support for memcmp, memcpy, memmove, memset.
17028 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
17029 * regex.c (memcmp, memcpy):
17030 Remove; we assume C89 now.
17032 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
17033 (__malloc_safe_bcopy): Remove; no longer needed.
17035 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
17036 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
17037 well either way, and we prefer signed to unsigned.
17039 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
17041 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
17042 closes the connection while we're reading (bug#9182).
17044 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
17046 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
17047 are specified (Bug#9168).
17049 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
17051 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
17052 Found by GCC static checking and --with-wide-int on a 32-bit host.
17054 2011-07-25 Eli Zaretskii <eliz@gnu.org>
17056 * xdisp.c (compute_display_string_pos): Fix logic of caching
17057 previous display string position. Initialize cached_prev_pos to
17058 -1. Fixes slow-down at the beginning of a buffer.
17060 2011-07-24 Eli Zaretskii <eliz@gnu.org>
17062 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
17063 for attrs[LFACE_FONTSET_INDEX].
17065 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
17067 * xml.c (parse_region): Remove unused local
17068 that was recently introduced.
17070 2011-07-23 Eli Zaretskii <eliz@gnu.org>
17072 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
17073 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
17075 * xdisp.c (move_it_in_display_line_to): Record the best matching
17076 position for TO_CHARPOS while scanning the line, and restore it on
17077 exit if none of the characters scanned was an exact match.
17078 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
17079 when exact match is impossible due to invisible text, and the
17080 lines are truncated.
17082 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
17084 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
17087 2011-07-22 Eli Zaretskii <eliz@gnu.org>
17089 Fix a significant slow-down of cursor motion with C-n, C-p,
17090 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
17091 auto-repeat under bidi redisplay in fontified buffers.
17092 * xdisp.c (compute_stop_pos_backwards): New function.
17093 (next_element_from_buffer): Call compute_stop_pos_backwards to
17094 find a suitable prev_stop when we find ourselves before
17096 (reseat): Don't look for prev_stop, as that could mean a very long
17098 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
17099 <cached_disp_overlay_modiff>: Cache for last found display string
17101 (compute_display_string_pos): Return the cached position if asked
17102 about the same buffer in the same area of character positions, and
17103 the buffer wasn't changed since the time the display string
17104 position was cached.
17106 2011-07-22 Eli Zaretskii <eliz@gnu.org>
17108 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
17109 is an integer, which is important for empty lines. (Bug#9149)
17111 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
17113 * frame.c (Fmodify_frame_parameters): In tty case, update the
17114 default face if necessary (Bug#4238).
17116 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
17118 * editfns.c (Fstring_to_char): No need to explain what a character
17119 is in the docstring (Bug#6576).
17121 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
17123 * xml.c (parse_region): Make sure we always return a tree.
17125 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
17127 * xml.c (parse_region): If a document contains only comments,
17130 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
17132 * xml.c (make_dom): Return comments, too.
17134 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
17137 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
17138 and the surrounding thread.
17139 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
17140 rather than fgets, and retry after EINTR. Otherwise, 'emacs
17141 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
17143 * s/openbsd.h (BROKEN_SIGIO): Define.
17144 * unexelf.c (unexec) [__OpenBSD__]:
17145 Don't update the .mdebug section of the Alpha COFF symbol table.
17147 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
17149 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
17152 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
17154 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
17155 This fixes some race conditions on the permissions of any newly
17158 * alloc.c (valid_pointer_p): Use pipe, not open.
17159 This fixes some permissions issues when debugging.
17161 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
17162 If fchown fails to set both uid and gid, try to set just gid,
17163 as that is sometimes allowed. Adjust the file's mode to eliminate
17164 setuid or setgid bits that are inappropriate if fchown fails.
17166 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
17168 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
17169 to compare Lisp_Objects.
17170 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
17171 global_gnutls_log_level, don't mistake it for a Lisp_Object.
17172 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
17174 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
17176 * lread.c (read_integer): Unread even EOF character.
17177 (read1): Likewise. Properly record start position of symbol.
17179 * lread.c (read1): Read `#:' as empty uninterned symbol if no
17180 symbol character follows.
17182 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
17184 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
17185 This works around a problem with the previous change to Fcopy_file.
17186 Recent glibc declares fchown with __attribute__((warn_unused_result)),
17187 and without this change, GCC might complain about discarding
17188 fchown's return value.
17190 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
17192 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
17194 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
17196 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
17198 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
17200 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
17201 it's used from the C level.
17203 * process.c: Use the same condition for POLL_FOR_INPUT in both
17204 keyboard.c and process.c (bug#1858).
17206 2011-07-09 Lawrence Mitchell <wence@gmx.li>
17208 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
17209 (Fgnutls_boot): Use it.
17211 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
17213 * doc.c (Fsubstitute_command_keys): Revert last change.
17215 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
17217 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
17218 quotes the next character, and doesn't affect other longer
17219 sequences (bug#8935).
17221 * lread.c (syms_of_lread): Clarify that is isn't only
17222 `eval-buffer' and `eval-defun' that's affected by
17223 `lexical-binding' (bug#8460).
17225 2011-07-15 Eli Zaretskii <eliz@gnu.org>
17227 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
17228 bidi redisplay when a line includes both an image and is truncated.
17230 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
17232 Fix minor problems found by static checking.
17233 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
17234 (elsz): Now a signed constant, not a size_t var. We prefer signed
17235 types to unsigned, to avoid integer comparison confusion. Without
17236 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
17237 "cannot optimize loop, the loop counter may overflow", a symptom
17239 * indent.c (Fvertical_motion): Mark locals as initialized.
17240 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
17242 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
17244 * search.c (Fre_search_backward): Mention `case-fold-search' in
17245 all the re_search_* functions (bug#8138).
17247 * keyboard.c (Fopen_dribble_file): Document when the file is
17250 2011-07-14 Eli Zaretskii <eliz@gnu.org>
17252 * bidi.c (bidi_dump_cached_states): Fix format of displaying
17255 Support bidi reordering of display and overlay strings.

17257 (compute_display_string_end): Accept additional argument STRING.
17258 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
17259 (reseat_to_string): Initialize bidi_it->string.s and
17260 bidi_it->string.schars.
17261 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
17262 NULL (avoids a crash in bidi_paragraph_init).
17263 Initialize itb.string.lstring.
17264 (init_iterator): Call bidi_init_it only of a valid
17265 buffer position was specified. Initialize paragraph_embedding to
17267 (reseat_to_string): Initialize the bidi iterator.
17268 (display_string): If we need to ignore text properties of
17269 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
17270 original value of -1 will not work with bidi.)
17271 (compute_display_string_pos): First arg is now struct
17272 `text_pos *'; all callers changed. Support display properties on
17274 (compute_display_string_end): Support display properties on Lisp
17276 (init_iterator, reseat_1, reseat_to_string): Initialize the
17277 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
17278 when iterating on a string not from display properties).
17279 (compute_display_string_pos, compute_display_string_end):
17280 Fix calculation of the object to scan. Fixes an error when using
17282 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
17283 base_level_stop; instead, set base_level_stop to BEGV.
17284 Fixes crashes in vertical-motion.
17285 (next_element_from_buffer): Improve commentary for when
17286 the iterator is before prev_stop.
17287 (init_iterator): Initialize bidi_p from the default value of
17288 bidi-display-reordering, not from buffer-local value. Use the
17289 buffer-local value only if initializing for buffer iteration.
17290 (handle_invisible_prop): Support invisible properties on strings
17291 that are being bidi-reordered.
17292 (set_iterator_to_next): Support bidi reordering of C strings and
17294 (next_element_from_string): Support bidi reordering of Lisp
17296 (handle_stop_backwards): Support Lisp strings as well.
17297 (display_string): Support display of R2L glyph rows.
17298 Use IT_STRING_CHARPOS when displaying from a Lisp string.
17299 (init_iterator): Don't initialize it->bidi_p for strings
17301 (reseat_to_string): Initialize it->bidi_p for strings here.
17302 (next_element_from_string, next_element_from_c_string)
17303 (next_element_from_buffer): Add xassert's for correspondence
17304 between IT's object being iterated and it->bidi_it.string
17306 (face_before_or_after_it_pos): Support bidi iteration.
17307 (next_element_from_c_string): Handle the case of the first string
17308 character that is not the first one in the visual order.
17309 (get_visually_first_element): New function, refactored from common
17310 parts of next_element_from_buffer, next_element_from_string, and
17311 next_element_from_c_string.
17312 (tool_bar_lines_needed, redisplay_tool_bar)
17313 (display_menu_bar): Force left-to-right direction. Add a FIXME
17314 comment for making that be controlled by a user option.
17315 (push_it, pop_it): Save and restore the state of the
17316 bidi iterator. Save and restore the bidi_p flag.
17317 (pop_it): Iterate out of display property for string iteration as
17319 (iterate_out_of_display_property): Support iteration over strings.
17320 (handle_single_display_spec): Set up it->bidi_it for iteration
17321 over a display string, and call bidi_init_it.
17322 (handle_single_display_spec, next_overlay_string)
17323 (get_overlay_strings_1, push_display_prop): Set up the bidi
17324 iterator for displaying display or overlay strings.
17325 (forward_to_next_line_start): Don't use the shortcut if
17327 (back_to_previous_visible_line_start): If handle_display_prop
17328 pushed the iterator stack, restore the internal state of the bidi
17329 iterator by calling bidi_pop_it same number of times.
17330 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
17331 and we are bidi-iterating, don't decrement the iterator position;
17332 instead, set the first_elt flag in the bidi iterator, to produce
17334 (reseat_1): Remove redundant setting of string_from_display_prop_p.
17335 (push_display_prop): xassert that we are iterating a buffer.
17336 (push_it, pop_it): Save and restore paragraph_embedding member.
17337 (handle_single_display_spec, next_overlay_string)
17338 (get_overlay_strings_1, reseat_1, reseat_to_string)
17339 (push_display_prop): Set up the `unibyte' member of bidi_it.string
17340 correctly. Don't assume unibyte strings are not bidi-reordered.
17341 (compute_display_string_pos)
17342 (compute_display_string_end): Fix handling the case of C string.
17343 (push_it, pop_it): Save and restore from_disp_prop_p.
17344 (handle_single_display_spec, push_display_prop): Set the
17345 from_disp_prop_p flag.
17346 (get_overlay_strings_1): Reset the from_disp_prop_p flag.
17347 (pop_it): Call iterate_out_of_display_property only if we are
17348 popping after iteration over a string that came from a display
17349 property. Fix a typo in popping stretch info. Add an assertion
17350 for verifying that the iterator position is in sync with the bidi
17352 (handle_single_display_spec, get_overlay_strings_1)
17353 (push_display_prop): Fix initialization of paragraph direction for
17354 string when that of the parent object is not yet determined.
17355 (reseat_1): Call bidi_init_it to resync the bidi
17356 iterator with IT's position. (Bug#7616)
17357 (find_row_edges): If ROW->start.pos gives position
17358 smaller than min_pos, use it as ROW->minpos. (Bug#7616)

17803 2011-07-05 Paul Eggert <eggert@cs.ucla.edu>
17805 Random fixes. E.g., (random) never returned negative values.
17806 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
17807 subseconds part to the entropy, as that's a bit more random.
17808 Prefer signed to unsigned, since the signedness doesn't matter and
17809 in general we prefer signed. When given a limit, use a
17810 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
17811 latter isn't right if USE_2_TAGS_FOR_INTS.
17812 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
17813 not 0..VALMASK. Don't discard "excess" bits that random () returns.
17815 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
17817 * textprop.c (text_property_stickiness):
17818 Obey Vtext_property_default_nonsticky.

17826 This is more efficient than Ffile_directory_p and avoids a minor race.
17828 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
17830 * buffer.c (Foverlay_put): Say what the return value is
17833 * fileio.c (barf_or_query_if_file_exists): Check first if the file
17834 is a directory before asking whether to use the file name
17836 (barf_or_query_if_file_exists): Make the "File is a directory"
17837 error be more correct.
17839 * fns.c (Frequire): Remove the mention of the .gz files, since
17840 that's installation-specific, but keep the mention of
17841 `get-load-suffixes'.
17843 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
17845 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

17850 * gnutls.c (Fgnutls_boot): Don't mention :verify-error.
17851 (syms_of_gnutls): Remove duplicate DEFSYM for
17852 Qgnutls_bootprop_verify_hostname_error, an error for
17853 Qgnutls_bootprop_verify_error (which is no longer used).
17855 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
17856 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
17857 Also (re)move comments that are misplaced or no longer relevant.
17859 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
17861 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

17889 * fns.c (Frequire): Mention .el.gz files (bug#7314).
17890 (Frequire): Mention get-load-suffixes.

17958 * eval.c (struct backtrace): Simplify and port the data structure.
17959 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
17960 signed bit field, as this assumption is not portable and it makes
17961 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
17962 "char debug_on_exit : 1" as this is not portable either; instead,
17963 use the portable "unsigned int debug_on_exit : 1". Remove unused
17964 member evalargs. Remove obsolete comments about cc bombing out.
17966 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>
17968 * xsettings.c: Include glib-object.h, gio/gio.h if HAVE_GSETTINGS.

18034 (emacs_fixed_new): Set priv->f to argument.
18035 (emacs_fixed_get_preferred_width)
18036 (emacs_fixed_get_preferred_height): Use min_width/height from
18037 frames size_hint to set minimum and natural (Bug#8919).
18038 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
18039 and use min_width/height from frames size_hint to set
18040 min_width/height (Bug#8919).

18133 (PRINTPREPARE, printchar, strout):
18134 Don't set size unless allocation succeeds.
18136 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
18137 for sizes. Check for string overflow more accurately.

18151 (read_integer): Radix is now EMACS_INT, not int,
18152 to improve quality of diagnostics for out-of-range radices.
18153 Calculate buffer size correctly for out-of-range radices.
18154 (read1): Check for integer overflow in radices, and in
18155 read-circle numbers.
18156 (read_escape): Avoid int overflow.
18157 (Fload, openp, read_buffer_size, read1)
18158 (substitute_object_recurse, read_vector, read_list, map_obarray):
18159 Use ptrdiff_t, not int, for sizes.

18181 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
18182 The following patches are for when GLYPH_DEBUG && !XASSERT.
18183 * dispextern.h (trace_redisplay_p, dump_glyph_string):
18184 * dispnew.c (flush_stdout):
18185 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
18186 Mark as externally visible.
18187 * dispnew.c (check_window_matrix_pointers): Now static.
18188 * dispnew.c (window_to_frame_vpos):
18189 * xfns.c (unwind_create_frame):

18196 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
18198 (debug_method_add): Use va_list and vsprintf rather than relying
18199 on undefined behavior with wrong number of arguments.
18200 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
18201 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
18202 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
18203 since we're not interested in debugging glyphs with old libraries.
18204 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
18205 GCC 4.6.0's static checking.
18207 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>

18236 * xfaces.c (face_at_buffer_position):
18237 * buffer.c (OVERLAY_COUNT_MAX): New macro.
18238 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
18239 (Fnext_overlay_change, Fprevious_overlay_change)
18240 (mouse_face_overlay_overlaps, Foverlays_in):
18241 Use ptrdiff_t, not int, for sizes.
18242 (overlays_at, overlays_in): Check for size-calculation overflow.
18244 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
18246 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
18247 (x_session_initialize): Do not assume string length fits in int.
18249 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
18250 This is unlikely, but can occur if DPI is outlandish.
18252 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
18253 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
18255 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
18256 * xrdb.c (magic_file_p, search_magic_path):
18257 Omit last arg SUFFIX; it was always 0. All callers changed.
18258 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
18260 * xfont.c (xfont_match): Avoid need for strlen.
18262 * xfns.c: Don't assume strlen fits in int.
18263 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
18265 * xdisp.c (message_log_check_duplicate): Return intmax_t,
18266 not unsigned long, as we prefer signed integers. All callers changed.
18267 Detect integer overflow in repeat count.
18268 (message_dolog): Don't assume print length fits in 39 bytes.
18269 (display_mode_element): Don't assume strlen fits in int.
18271 * termcap.c: Don't assume sizes fit in int and never overflow.
18272 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
18273 (gobble_line): Check for size-calculation overflow.
18275 * minibuf.c (Fread_buffer):
18276 * lread.c (intern, intern_c_string):
18277 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
18278 Don't assume string length fits in int.
18280 * keyboard.c (parse_tool_bar_item):
18281 * gtkutil.c (style_changed_cb): Avoid need for strlen.
18283 * font.c: Don't assume string length fits in int.
18284 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
18285 Use ptrdiff_t, not int.
18286 (font_intern_prop): Don't assume string length fits in int.
18287 Don't assume integer property fits in fixnum.
18288 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
18290 * filelock.c: Fix some buffer overrun and integer overflow issues.
18291 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
18292 Reformulate so as not to need the command string.
18293 Invoke gzip -cd rather than gunzip, as it's more portable.
18294 (lock_info_type, lock_file_1, lock_file):
18295 Don't assume pid_t and time_t fit in unsigned long.
18296 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
18297 (current_lock_owner): Prefer signed type for sizes.
18298 Use memcpy, not strncpy, where memcpy is what is really wanted.
18299 Don't assume (via atoi) that time_t and pid_t fit in int.
18300 Check for time_t and/or pid_t out of range, e.g., via a network share.
18301 Don't alloca where an auto var works fine.
18303 * fileio.c: Fix some integer overflow issues.
18304 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
18305 Don't assume string length fits in int.
18306 (directory_file_name): Don't assume string length fits in long.
18307 (make_temp_name): Don't assume pid fits in int, or that its print
18308 length is less than 20.
18310 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
18312 * coding.c (make_subsidiaries): Don't assume string length fits in int.
18314 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
18316 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
18317 We prefer signed integers, even for size calculations.
18319 * emacs.c: Don't assume string length fits in 'int'.
18320 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
18321 (main): Don't invoke strlen when not needed.
18323 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
18324 (XD_DEBUG_MESSAGE): Don't waste a byte.
18326 * callproc.c (getenv_internal_1, getenv_internal)
18327 (Fgetenv_internal):
18328 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
18330 * lread.c (invalid_syntax): Omit length argument.
18331 All uses changed. This doesn't fix a bug, but it simplifies the
18332 code away from its former Hollerith-constant appearance, and it's
18333 one less 'int' to worry about when looking at integer-overflow issues.
18334 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
18336 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
18337 This didn't break anything, but it didn't help either.
18338 It's confusing to put a bogus integer in a place where the actual
18339 value does not matter.
18340 (LIST_END_P): Remove unused macro and its bogus comment.
18341 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
18343 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
18344 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
18346 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
18347 We prefer signed types, and the value cannot exceed the EMACS_INT
18348 range anyway (because otherwise the length would not be representable).
18349 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
18350 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
18351 This avoids a GCC warning when WIDE_EMACS_INT.
18353 * indent.c (sane_tab_width): New function.
18354 (current_column, scan_for_column, Findent_to, position_indentation)
18355 (compute_motion): Use it. This is just for clarity.
18356 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
18358 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
18360 * lisp.h (lint_assume): New macro.
18361 * composite.c (composition_gstring_put_cache):
18362 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
18364 * editfns.c, insdel.c:
18365 Omit unnecessary forward decls, to simplify future changes.
18367 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
18369 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
18371 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
18372 Use much-faster test for byte-length change.
18373 Don't assume string byte-length fits in 'int'.
18374 Check that character arg fits in 'int'.
18375 (mapcar1): Declare byte as byte, for clarity.
18377 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
18379 * fns.c (concat): Catch string overflow earlier.
18380 Do not rely on integer wraparound.
18382 * dispextern.h (struct it.overlay_strings_charpos)
18383 (struct it.selective): Now EMACS_INT, not int.
18384 * xdisp.c (forward_to_next_line_start)
18385 (back_to_previous_visible_line_start)
18386 (reseat_at_next_visible_line_start, next_element_from_buffer):
18387 Don't arbitrarily truncate the value of 'selective' to int.
18389 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
18391 * composite.c: Don't truncate sizes to 'int'.
18392 (composition_gstring_p, composition_reseat_it)
18393 (composition_adjust_point): Use EMACS_INT, not int.
18394 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
18395 not EMACS_UINT, for indexes.
18397 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
18399 * buffer.c: Include <verify.h>.
18400 (struct sortvec.priority, struct sortstr.priority):
18401 Now EMACS_INT, not int.
18402 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
18403 (struct sortstr.size, record_overlay_string)
18404 (struct sortstrlist.size, struct sortlist.used):
18405 Don't truncate size to int.
18406 (record_overlay_string): Check for size-calculation overflow.
18407 (init_buffer_once): Check at compile-time, not run-time.
18409 2011-06-22 Jim Meyering <meyering@redhat.com>
18411 Don't leak an XBM-image-sized buffer
18412 * image.c (xbm_load): Free the image buffer after using it.
18414 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
18417 * composite.c (find_automatic_composition): Omit needless 'return 0;'
18418 that Sun C diagnosed.
18419 * fns.c (secure_hash): Fix pointer signedness issue.
18420 * intervals.c (static_offset_intervals): New function.
18421 (offset_intervals): Use it.
18423 2011-06-21 Leo Liu <sdl.web@gmail.com>
18426 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
18429 * fns.c (secure_hash): Rename from crypto_hash_function and change
18430 the first arg to accept symbols.
18431 (Fsecure_hash): New primitive.
18432 (syms_of_fns): New symbols.
18434 2011-06-20 Deniz Dogan <deniz@dogan.se>
18436 * process.c (Fset_process_buffer): Clarify return value in
18439 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
18441 * dispnew.c (add_window_display_history): Use BVAR.
18443 * xdisp.c (debug_method_add): Use BVAR.
18444 (check_window_end, dump_glyph_matrix, dump_glyph)
18445 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
18447 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
18450 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
18451 check till after the cache is created in init_frame_faces.
18453 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
18455 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
18457 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
18459 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
18460 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
18461 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
18463 Improve buffer-overflow checking (Bug#8873).
18464 * fileio.c (Finsert_file_contents):
18465 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
18466 Remove the old (too-loose) buffer overflow checks.
18467 They weren't needed, since make_gap checks for buffer overflow.
18468 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
18469 The old code merely checked for Emacs fixnum overflow, and relied
18470 on undefined (wraparound) behavior. The new code avoids undefined
18471 behavior, and also checks for ptrdiff_t and/or size_t overflow.
18473 * editfns.c (Finsert_char): Don't dump core with very negative counts.
18474 Tune. Don't use wider integers than needed. Don't use alloca.
18475 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
18477 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
18479 * insdel.c, lisp.h (buffer_overflow): New function.
18480 (insert_from_buffer_1, replace_range, replace_range_2):
18481 * insdel.c (make_gap_larger):
18482 * editfns.c (Finsert_char):
18483 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
18485 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
18487 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
18489 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
18491 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
18492 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
18494 * fileio.c: Don't assume EMACS_INT fits in off_t.
18495 (emacs_lseek): New static function.
18496 (Finsert_file_contents, Fwrite_region): Use it.
18497 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
18499 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
18501 * fns.c: Don't overflow int when computing a list length.
18502 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
18503 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
18504 truncation on 64-bit hosts. Check for QUIT every
18505 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
18506 faster and is responsive enough.
18507 (Flength): Report an error instead of overflowing an integer.
18508 (Fsafe_length): Return a float if the value is not representable
18509 as a fixnum. This shouldn't happen except in contrived situations.
18510 (Fnthcdr, Fsort): Don't assume list length fits in int.
18511 (Fcopy_sequence): Don't assume vector length fits in int.
18513 * alloc.c: Check that resized vectors' lengths fit in fixnums.
18514 (header_size, word_size): New constants.
18515 (allocate_vectorlike): Don't check size overflow here.
18516 (allocate_vector): Check it here instead, since this is the only
18517 caller of allocate_vectorlike that could cause overflow.
18518 Check that the new vector's length is representable as a fixnum.
18520 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
18521 The previous code was bogus. For example, next_almost_prime (32)
18522 returned 39, which is undesirable as it is a multiple of 3; and
18523 next_almost_prime (24) returned 25, which is a multiple of 5 so
18524 why was the code bothering to check for multiples of 7?
18526 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
18528 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
18530 Variadic C functions now count arguments with ptrdiff_t.
18531 This partly undoes my 2011-03-30 change, which replaced int with size_t.
18532 Back then I didn't know that the Emacs coding style prefers signed int.
18533 Also, in the meantime I found a few more instances where arguments
18534 were being counted with int, which may truncate counts on 64-bit
18535 machines, or EMACS_INT, which may be unnecessarily wide.
18536 * lisp.h (struct Lisp_Subr.function.aMANY)
18537 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
18538 Arg counts are now ptrdiff_t, not size_t.
18539 All variadic functions and their callers changed accordingly.
18540 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
18541 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
18542 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
18543 * callint.c (Fcall_interactively): Check arg count for overflow,
18544 to avoid potential buffer overrun. Use signed char, not 'int',
18545 for 'varies' array, so that we needn't bother to check its size
18546 calculation for overflow.
18547 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
18548 * eval.c (apply_lambda):
18549 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
18550 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
18551 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
18553 * callint.c (Fcall_interactively): Don't use index var as event count.
18555 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
18556 * mem-limits.h (SIZE): Remove; no longer used.
18558 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
18560 Remove unnecessary casts.
18561 * xterm.c (x_term_init):
18562 * xfns.c (x_set_border_pixel):
18563 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
18564 These aren't needed now that we assume ANSI C.
18566 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
18567 It's more likely to cause problems (due to unsigned overflow)
18570 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
18572 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
18574 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
18576 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
18578 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
18580 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
18582 GLYPH_CODE_FACE returns EMACS_INT, not int.
18583 * dispextern.h (merge_faces):
18584 * xfaces.c (merge_faces):
18585 * xdisp.c (get_next_display_element, next_element_from_display_vector):
18586 Don't assume EMACS_INT fits in int.
18588 * character.h (CHAR_VALID_P): Remove unused parameter.
18589 * fontset.c, lisp.h, xdisp.c: All uses changed.
18591 * editfns.c (Ftranslate_region_internal): Omit redundant test.
18593 * fns.c (concat): Minor tuning based on overflow analysis.
18594 This doesn't fix any bugs. Use int to hold character, instead
18595 of constantly refetching from Emacs object. Use XFASTINT, not
18596 XINT, for value known to be a character. Don't bother comparing
18597 a single byte to 0400, as it's always less.
18599 * floatfns.c (Fexpt):
18600 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
18602 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
18605 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
18607 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
18608 Without this fix, on a 64-bit host (aset S 0 4294967386) would
18609 incorrectly succeed when S was a string, because 4294967386 was
18610 truncated before it was used.
18612 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
18613 Otherwise, an out-of-range integer could cause undefined behavior
18616 * composite.c: Use int, not EMACS_INT, for characters.
18617 (fill_gstring_body, composition_compute_stop_pos): Use int, not
18618 EMACS_INT, for values that are known to be in character range.
18619 This doesn't fix any bugs but is the usual style inside Emacs and
18620 may generate better code on 32-bit machines.
18622 Make sure a 64-bit char is never passed to ENCODE_CHAR.
18623 This is for reasons similar to the recent CHAR_STRING fix.
18624 * charset.c (Fencode_char): Check that character arg is actually
18625 a character. Pass an int to ENCODE_CHAR.
18626 * charset.h (ENCODE_CHAR): Verify that the character argument is no
18627 wider than 'int', as a compile-time check to prevent future regressions
18630 * character.c (char_string): Remove unnecessary casts.
18632 Make sure a 64-bit char is never passed to CHAR_STRING.
18633 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
18634 by silently ignoring the top 32 bits, allowing some values
18635 that were far too large to be valid characters.
18636 * character.h: Include <verify.h>.
18637 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
18638 arguments are no wider than unsigned, as a compile-time check
18639 to prevent future regressions in this area.
18641 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
18642 (Fsubst_char_in_region):
18644 * xdisp.c (decode_mode_spec_coding):
18645 Adjust to CHAR_STRING's new requirement.
18646 * editfns.c (Finsert_char, Fsubst_char_in_region):
18647 * fns.c (concat): Check that character args are actually
18648 characters. Without this test, these functions did the wrong
18649 thing with wildly out-of-range values on 64-bit hosts.
18651 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
18652 These casts should not be needed on 32-bit hosts, either.
18653 * keyboard.c (read_char):
18654 * lread.c (Fload): Remove casts to unsigned.
18656 * lisp.h (UNSIGNED_CMP): New macro.
18657 This fixes comparison bugs on 64-bit hosts.
18658 (ASCII_CHAR_P): Use it.
18659 * casefiddle.c (casify_object):
18660 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
18661 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
18662 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
18663 * dispextern.h (FACE_FROM_ID):
18664 * keyboard.c (read_char): Use UNSIGNED_CMP.
18666 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
18667 not to EMACS_INT, to avoid GCC warning.
18669 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
18671 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
18672 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
18673 isn't needed on 32-bit machines.
18675 * buffer.c (Fgenerate_new_buffer_name):
18676 Use EMACS_INT for count, not int.
18677 (advance_to_char_boundary): Return EMACS_INT, not int.

19300 (bidi_paragraph_init, bidi_resolve_explicit_1)
19301 (bidi_level_of_next_char): Call bidi_fetch_char and

19308 instead of using explicit *_CHAR codes.
19309 (bidi_resolve_explicit, bidi_resolve_weak):

19318 (bidi_level_of_next_char): Don't try to lookup the cache for the
19319 next/previous character if nothing is cached there yet, or if we
19320 were just reseat()'ed to a new position.
19322 * xdisp.c (set_cursor_from_row): Set start and stop points
19323 according to the row's direction when priming the loop that looks
19324 for the glyph on which to display cursor.

19326 (display_prop_intangible_p): Reimplement to call
19327 handle_display_spec instead of single_display_spec_intangible_p.
19328 Accept 3 additional arguments needed by handle_display_spec.
19329 This fixes incorrect cursor motion across display property with complex
19330 values: lists, `(when COND...)' forms, etc.

19332 lists with the argument STRING its top-level element.
19333 (display_prop_string_p): Fix the condition for processing a
19334 property that is a list to be consistent with handle_display_spec.

19336 last portion of handle_display_prop.
19337 (compute_display_string_pos): Accept additional argument
19338 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
19339 value of a `display' property is a "replacing spec".
19340 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
19341 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
19342 the display property, but just return a value indicating whether
19343 the display property will replace the characters it covers.
19344 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
19345 frame_window_p members of struct bidi_it.
19346 (compute_display_string_pos, compute_display_string_end):

19352 * keyboard.c (adjust_point_for_property): Adjust the call to
19353 display_prop_intangible_p to its new signature.

19369 All callers changed. (Bug#8762)
19371 * gnutls.c: Use Emacs's memory allocators.
19372 Without this change, the gnutls library would invoke malloc etc.
19373 directly, which causes problems on non-SYNC_INPUT hosts, and which
19374 runs afoul of improving memory_full behavior. (Bug#8761)
19375 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
19376 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
19377 xfree instead of the default malloc, realloc, free.
19378 (Fgnutls_boot): No need to check for memory allocation failure,
19379 since xmalloc does that for us.
19381 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)

19401 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
19402 for hashes and hash indexes, instead of 'unsigned' and 'int'.
19403 * alloc.c (allocate_vectorlike):
19404 Check for overflow in vector size calculations.
19405 * ccl.c (ccl_driver):
19406 Check for overflow when converting EMACS_INT to int.

19408 need to be updated by these changes.
19409 * fns.c (make_hash_table, maybe_resize_hash_table):
19410 Check for integer overflow with large hash tables.
19411 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
19412 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
19413 (SXHASH_REDUCE): New macro.
19414 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
19415 Use it instead of discarding useful hash info with large hash values.
19416 (sxhash_float): New function.
19417 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
19418 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
19419 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
19420 Rewrite to use FIXNUM_BITS, as this simplifies things.
19421 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
19422 Adjust signatures to match updated version of code.
19423 (consing_since_gc): Now EMACS_INT, since a single hash table can
19424 use more than INT_MAX bytes.

19473 Make it possible to run ./temacs.
19475 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
19476 syms_of_callproc does the same thing. Remove test for
19477 "initialized", do it in the caller.

19537 * fns.c (to_uchar): Define.
19538 (crypto_hash_function): Use it to convert some newly-signed

19550 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
19551 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
19552 to hold a serial number that is too large for a fixnum.
19553 (Fdbus_method_return_internal, Fdbus_method_error_internal):
19554 Check for serial numbers out of range. Decode any serial number
19555 that was so large that it became a float. (Bug#8722)
19557 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
19558 (Fdbus_call_method, Fdbus_call_method_asynchronously):
19559 Use XFASTINT rather than XUINT when numbers are nonnegative.
19560 (xd_append_arg, Fdbus_method_return_internal):
19561 (Fdbus_method_error_internal): Likewise. Also, for unsigned
19562 arguments, check that Lisp number is nonnegative, rather than
19563 silently wrapping negative numbers around. (Bug#8722)
19564 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
19567 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
19569 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
19571 ccl: Add integer overflow checks.
19572 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
19573 (IN_INT_RANGE): New macros.
19574 (ccl_driver): Use them to check for integer overflow when
19575 decoding a CCL program. Many of the new checks are whether XINT (x)
19576 fits in int; it doesn't always, on 64-bit hosts. The new version
19577 doesn't catch all possible integer overflows, but it's an
19578 improvement. (Bug#8719)
19580 * alloc.c (make_event_array): Use XINT, not XUINT.
19581 There's no need for unsigned here.
19583 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
19584 This follows up to the 2011-05-06 change that substituted uintptr_t
19585 for EMACS_INT. This case wasn't caught back then.
19587 Rework Fformat to avoid integer overflow issues.
19588 * editfns.c: Include <float.h> unconditionally, as it's everywhere
19589 now (part of C89). Include <verify.h>.
19590 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
19591 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
19592 (Fformat): Avoid the prepass trying to compute sizes; it was only
19593 approximate and thus did not catch overflow reliably. Instead, walk
19594 through the format just once, formatting and computing sizes as we go,
19595 checking for integer overflow at every step, and allocating a larger
19596 buffer as needed. Keep track separately whether the format is
19597 multibyte. Keep only the most-recently calculated precision, rather
19598 than them all. Record whether each argument has been converted to
19599 string. Use EMACS_INT, not int, for byte and char and arg counts.
19600 Support field widths and precisions larger than INT_MAX. Avoid
19601 sprintf's undefined behavior with conversion specifications such as %#d
19602 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
19603 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
19604 formatting out-of-range floating point numbers with int
19605 formats. (Bug#8668)
19607 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
19609 * data.c: Avoid integer truncation in expressions involving floats.
19610 * data.c: Include <intprops.h>.
19611 (arith_driver): When there's an integer overflow in an expression
19612 involving floating point, convert the integers to floating point
19613 so that the resulting value does not suffer from catastrophic
19614 integer truncation. For example, on a 64-bit host (* 4
19615 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
19616 Do not rely on undefined behavior after integer overflow.
19618 merge count_size_as_multibyte, parse_str_to_multibyte
19619 * character.c, character.h (count_size_as_multibyte):
19620 Rename from parse_str_to_multibyte; all uses changed.
19621 Check for integer overflow.
19622 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
19623 since it's now a duplicate of the other. This is more of
19624 a character than a buffer op, so better that it's in character.c.
19625 * fns.c, print.c: Adjust to above changes.
19627 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
19629 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
19631 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
19633 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
19634 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
19635 (x_clipboard_manager_save): Now static.
19636 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
19638 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
19639 (crypto_hash_function): Now static.
19640 Fix pointer signedness problems. Avoid unnecessary initializations.
19642 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
19644 * termhooks.h (Vselection_alist): Make it terminal-local.
19646 * terminal.c (create_terminal): Initialize it.
19648 * xselect.c: Support for clipboard managers.
19649 (Vselection_alist): Move to termhooks.h as terminal-local var.
19650 (LOCAL_SELECTION): New macro.
19651 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
19652 (symbol_to_x_atom): Remove gratuitous arg.
19653 (x_handle_selection_request, lisp_data_to_selection_data)
19654 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
19655 (x_own_selection, x_get_local_selection, x_convert_selection):
19656 New arg, specifying work frame. Use terminal-local Vselection_alist.
19657 (some_frame_on_display): Delete unused function.
19658 (Fx_own_selection_internal, Fx_get_selection_internal)
19659 (Fx_disown_selection_internal, Fx_selection_owner_p)
19660 (Fx_selection_exists_p): New optional frame arg.
19661 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
19662 (x_handle_selection_clear): Don't treat other terminals with the
19663 same keyboard specially. Use the terminal-local Vselection_alist.
19664 (x_clear_frame_selections): Use Frun_hook_with_args.
19666 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
19668 * xterm.h: Add support for those atoms.
19670 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
19672 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
19673 (converted_selections, conversion_fail_tag): New global variables.
19674 (x_selection_request_lisp_error): Free the above.
19675 (x_get_local_selection): Remove unnecessary code.
19676 (x_reply_selection_request): Args changed; handle arbitrary array
19677 of converted selections stored in converted_selections.
19678 Separate the XChangeProperty and SelectionNotify steps.
19679 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
19680 (x_convert_selection): New function.
19681 (x_handle_selection_event): Simplify.
19682 (x_get_foreign_selection): Don't ignore incoming requests while
19683 waiting for an answer; this will fail when we implement
19684 SAVE_TARGETS, and seems unnecessary anyway.
19685 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
19686 (Vx_sent_selection_functions): Doc fix.
19688 2011-05-26 Leo Liu <sdl.web@gmail.com>
19690 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
19692 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19694 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
19696 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
19697 for fringe update if it has periodic bitmap.
19698 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
19699 and fringe_bitmap_periodic_p.
19701 * fringe.c (get_fringe_bitmap_data): New function.
19702 (draw_fringe_bitmap_1, update_window_fringes): Use it.
19703 (update_window_fringes): Record periodicity of fringe bitmap in glyph
19704 row. Mark glyph row for fringe update if periodicity changed.
19706 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
19707 for fringe update unless it has periodic bitmap.
19709 2011-05-25 Kenichi Handa <handa@m17n.org>
19711 * xdisp.c (get_next_display_element): Set correct it->face_id for
19712 a static composition.
19714 2011-05-24 Leo Liu <sdl.web@gmail.com>
19717 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
19719 * fns.c (crypto_hash_function, Fsha1): New function.
19720 (Fmd5): Use crypto_hash_function.
19721 (syms_of_fns): Add Ssha1.
19723 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
19725 * gnutls.c: Remove unused macros.
19726 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
19727 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
19728 Remove macros that are defined and never used.
19729 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
19731 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
19733 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
19734 (Fx_get_selection_internal): Minor cleanup.
19735 (Fx_own_selection_internal): Rename arguments for consistency with
19738 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
19740 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
19742 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
19744 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
19746 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19748 * dispnew.c (scrolling_window): Don't exclude the case that the
19749 last enabled row in the desired matrix touches the bottom boundary.
19751 2011-05-21 Glenn Morris <rgm@gnu.org>
19753 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
19754 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
19755 and add some more files.
19757 2011-05-20 Eli Zaretskii <eliz@gnu.org>
19759 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
19760 report_file_error introduced by the change from 2011-05-07.
19762 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
19764 * systime.h (Time): Define only if emacs is defined.
19765 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
19766 where the include path doesn't have X11/X.h by default. See
19767 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
19769 2011-05-20 Kenichi Handa <handa@m17n.org>
19771 * composite.c (find_automatic_composition): Fix previous change.
19773 2011-05-20 Glenn Morris <rgm@gnu.org>
19775 * lisp.mk: New file, split from Makefile.in.
19776 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
19777 (shortlisp): Remove.
19778 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
19780 2011-05-19 Glenn Morris <rgm@gnu.org>
19782 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
19783 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
19784 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
19785 (lisp): Set the order to that of loadup.el.
19786 (shortlisp): Make it a copy of $lisp.
19787 (SOME_MACHINE_LISP): Remove.
19788 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
19789 Use just $shortlisp, not $SOME_MACHINE_LISP too.
19791 2011-05-18 Kenichi Handa <handa@m17n.org>
19793 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
19794 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
19795 (find_automatic_composition): Mostly rewrite for efficiency.
19797 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
19799 * makefile.w32-in: Update dependencies.
19801 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
19803 * menu.c: Include limits.h (fixes the MS-Windows build broken by
19804 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
19806 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
19808 Fix some integer overflow issues, such as string length overflow.
19810 * insdel.c (count_size_as_multibyte): Check for string overflow.
19812 * character.c (lisp_string_width): Check for string overflow.
19813 Use EMACS_INT, not int, for string indexes and lengths; in
19814 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
19815 the resulting string length overflows an EMACS_INT; instead,
19816 report a string overflow if no precision given. When checking for
19817 precision exhaustion, use a check that cannot possibly have
19818 integer overflow. (Bug#8675)
19819 * character.h (lisp_string_width): Adjust to new signature.
19821 * alloc.c (string_overflow): New function.
19822 (Fmake_string): Use it. This doesn't change behavior, but saves
19823 a few bytes and will simplify future changes.
19824 * character.c (string_escape_byte8): Likewise.
19825 * lisp.h (string_overflow): New decl.
19827 Fixups, following up to the user-interface timestamp change.
19828 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
19829 for UI timestamps, instead of unsigned long.
19830 * msdos.c (mouse_get_pos): Likewise.
19831 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
19832 * w32gui.h (Time): Define by including "systime.h" rather than by
19833 declaring it ourselves. (Bug#8664)
19835 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
19836 * image.c (clear_image_cache): Likewise.
19838 * term.c (term_mouse_position): Don't assume time_t wraparound.
19840 Be more systematic about user-interface timestamps.
19841 Before, the code sometimes used 'Time', sometimes 'unsigned long',
19842 and sometimes 'EMACS_UINT', to represent these timestamps.
19843 This change causes it to use 'Time' uniformly, as that's what X uses.
19844 This makes the code easier to follow, and makes it easier to catch
19845 integer overflow bugs such as Bug#8664.
19846 * frame.c (Fmouse_position, Fmouse_pixel_position):
19847 Use Time, not unsigned long, for user-interface timestamps.
19848 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
19849 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
19850 * keyboard.h (last_event_timestamp): Likewise.
19851 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
19852 * menu.h (xmenu_show): Likewise.
19853 * term.c (term_mouse_position): Likewise.
19854 * termhooks.h (struct input_event.timestamp): Likewise.
19855 (struct terminal.mouse_position_hook): Likewise.
19856 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
19857 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
19858 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
19859 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
19860 what it was before.
19861 * menu.h, termhooks.h: Include "systime.h", for Time.
19863 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
19864 Don't assume that the difference between two unsigned long values
19865 can fit into an integer. At this point, we know button_down_time
19866 <= event->timestamp, so the difference must be nonnegative, so
19867 there's no need to cast the result if double-click-time is
19868 nonnegative, as it should be; check that it's nonnegative, just in
19869 case. This bug is triggered when events are more than 2**31 ms
19870 apart (about 25 days). (Bug#8664)
19872 * xselect.c (last_event_timestamp): Remove duplicate decl.
19873 (x_own_selection): Remove needless cast to unsigned long.
19875 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
19876 that always fit in int. Use a sentinel instead of a counter, to
19877 avoid a temp and to allay GCC's concerns about possible int overflow.
19878 * frame.h (struct frame): Use int for menu_bar_items_used
19879 instead of EMACS_INT, since it always fits in int.
19881 * menu.c (grow_menu_items): Check for int overflow.
19883 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
19885 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
19886 Before, the code was not consistent. These values cannot exceed
19887 2**31 - 1 so there's no need to make them unsigned.
19888 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
19889 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
19890 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
19892 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
19894 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
19895 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
19896 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
19897 presumably because the widths might not match.
19899 * window.c (size_window): Avoid needless test at loop start.
19901 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
19903 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
19905 2011-05-12 Drew Adams <drew.adams@oracle.com>
19907 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
19909 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19911 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
19912 `width' to `bar_area_x' and `bar_area_width', respectively.
19913 (x_scroll_run): Take account of fringe background extension.
19915 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
19916 Rename local vars `left' and `width' to `bar_area_x' and
19917 `bar_area_width', respectively.
19918 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
19919 background extension.
19921 2011-05-10 Jim Meyering <meyering@redhat.com>
19923 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
19925 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
19927 * image.c (Finit_image_library): Return t for built-in image types,
19928 like pbm and xbm. (Bug#8640)
19930 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
19932 * w32menu.c (set_frame_menubar): Fix submenu allocation.
19934 2011-05-07 Eli Zaretskii <eliz@gnu.org>
19936 * w32console.c (Fset_screen_color): Doc fix.
19937 (Fget_screen_color): New function.
19938 (syms_of_ntterm): Defsubr it.
19940 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
19941 unlink the temporary file if Fcall_process didn't create it in the
19943 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
19944 child process will be redirected to a file specified with `:file'.
19945 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
19946 cue to call_process_cleanup not to close that handle.
19948 2011-05-07 Ben Key <bkey76@gmail.com>
19950 * makefile.w32-in: The bootstrap-temacs rule now makes use of
19951 one of two shell specific rules, either bootstrap-temacs-CMD or
19952 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
19953 to the previous implementation of the bootstrap-temacs rule.
19954 The bootstrap-temacs-CMD rule is similar to the previous
19955 implementation of the bootstrap-temacs rule except that it
19956 makes use of the ESC_CFLAGS variable instead of the CFLAGS
19959 These changes, along with some changes to nt/configure.bat,
19960 nt/gmake.defs, and nt/nmake.defs, are required to extend my
19961 earlier fix to add support for --cflags and --ldflags options
19962 that include quotes so that it works whether make uses cmd or
19965 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
19967 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
19968 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
19970 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
19971 a string. Handle both cases.
19972 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
19973 (Fdbus_register_method): Use Qinvalid_function.
19975 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
19977 * makefile.w32-in: Update dependencies.
19978 (LISP_H): Add inttypes.h and stdin.h.
19979 (PROCESS_H): Add unistd.h.
19981 2011-05-06 Eli Zaretskii <eliz@gnu.org>
19983 * lread.c: Include limits.h (fixes the MS-Windows build broken by
19984 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
19986 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
19988 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
19990 * term.c (vfatal): Remove stray call to va_end.
19991 It's not needed and the C Standard doesn't allow it here anyway.
19993 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
19994 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
19996 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
19999 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
20001 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
20003 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
20005 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
20007 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
20009 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
20010 * charset.c (Fdefine_charset_internal): Don't initialize
20011 charset.code_space[15]. The value was garbage, on hosts with
20012 32-bit int (Bug#8600).
20014 * lread.c (read_integer): Be more consistent with string-to-number.
20015 Use string_to_number to do the actual conversion; this avoids
20016 rounding errors and fixes some other screwups. Without this fix,
20017 for example, #x1fffffffffffffff was misread as -2305843009213693952.
20018 (digit_to_number): Move earlier, for benefit of read_integer.
20019 Return -1 if the digit is out of range for the base, -2 if it is
20020 not a digit in any supported base. (Bug#8602)
20022 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
20024 * dispnew.c (scrolling_window): Return 1 if we scrolled,
20025 to match comment at start of function. This also removes a
20026 GCC warning about overflow in a 32+64-bit port.
20028 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
20030 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
20031 Reported by Stefan Monnier in
20032 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
20033 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
20034 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
20036 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
20037 (EMACS_UINTPTR): Likewise, with uintptr_t.
20039 * lisp.h: Prefer 64-bit EMACS_INT if available.
20040 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
20041 on 32-bit hosts that have 64-bit int, so that they can access
20043 However, temporarily disable this change unless the temporary
20044 symbol WIDE_EMACS_INT is defined.
20046 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
20048 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
20049 This removes an assumption that EMACS_INT and long are the same
20050 width as pointers. The assumption is true for Emacs porting targets
20051 now, but we want to make other targets possible.
20052 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
20053 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
20054 In the rest of the code, change types of integers that hold casted
20055 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
20056 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
20057 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
20058 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
20059 No need to cast type when ORing.
20060 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
20061 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
20062 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
20063 assume EMACS_INT is the same width as char *.
20064 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
20065 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
20066 Remove no-longer-needed casts.
20067 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
20068 (xg_tool_bar_help_callback, xg_make_tool_item):
20069 Use EMACS_INTPTR to hold an integer
20070 that will be cast to void *; this can avoid a GCC warning
20071 if EMACS_INT is not the same width as void *.
20072 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
20073 * xdisp.c (display_echo_area_1, resize_mini_window_1):
20074 (current_message_1, set_message_1):
20075 Use a local to convert to proper width without a cast.
20076 * xmenu.c (dialog_selection_callback): Likewise.
20078 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
20079 Also, don't assume VALBITS / RAND_BITS is less than 5,
20080 and don't rely on undefined behavior when shifting a 1 left into
20082 * lisp.h (get_random): Change signature to match.
20084 * lread.c (hash_string): Use size_t, not int, for hash computation.
20085 Normally we prefer signed values; but hashing is special, because
20086 it's better to use unsigned division on hash table sizes so that
20087 the remainder is nonnegative. Also, size_t is the natural width
20088 for hashing into memory. The previous code used 'int', which doesn't
20089 retain enough info to hash well into very large tables.
20090 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
20092 * dbusbind.c: Don't possibly lose pointer info when converting.
20093 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
20094 Use XPNTR rather than XHASH, so that the high-order bits of
20095 the pointer aren't lost when converting through void *.
20097 * eval.c (Fautoload): Don't double-shift a pointer.
20099 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
20101 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
20103 * gnutls.c (DEF_GNUTLS_FN):
20104 * image.c (DEF_IMGLIB_FN): Make function pointers static.
20106 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
20108 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
20111 2011-05-05 Eli Zaretskii <eliz@gnu.org>
20113 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
20114 New version that can reserve upto 2GB of heap space.
20116 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
20118 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
20120 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
20122 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
20123 `gnutls_certificate_set_x509_key_file'.
20125 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
20127 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
20128 Update dependencies.
20130 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
20132 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
20133 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
20134 Remove unused parameter `fildes'.
20135 * process.c (read_process_output, send_process): Don't pass it.
20137 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
20139 Fix previous change: the library cache is defined in w32.c.
20140 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
20141 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
20143 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
20145 Implement dynamic loading of GnuTLS on Windows.
20147 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
20148 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
20149 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
20152 * gnutls.c (Qgnutls_dll): Define.
20153 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
20154 (gnutls_*): Declare function pointers.
20155 (init_gnutls_functions): New function to initialize function pointers.

20158 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
20159 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
20160 (emacs_gnutls_write, emacs_gnutls_read)
20161 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
20162 (Fgnutls_available_p): New function.
20163 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
20164 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
20165 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
20167 * image.c: Include w32.h.
20168 (Vimage_type_cache): Delete.

20170 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
20171 (w32_delayed_load): Move to w32.c.
20173 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
20175 * w32.c (QCloaded_from, Vlibrary_cache): Define.
20176 (w32_delayed_load): Move from image.c. When loading a library, record
20177 its filename in the :loaded-from property of the library id.
20178 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
20179 Initialize and staticpro them.
20180 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
20182 * process.c: Include lisp.h before w32.h, not after.
20183 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
20184 instead of gnutls_record_check_pending.
20186 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
20188 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
20190 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
20191 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
20194 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
20196 * xterm.c (x_set_frame_alpha): Do not set property on anything
20197 else than FRAME_X_OUTER_WINDOW (Bug#8608).
20199 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
20201 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
20203 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
20205 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
20206 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)

20215 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
20217 * callproc.c: Indentation fixup.
20219 * sysdep.c (wait_for_termination_1): Make static.
20220 (wait_for_termination, interruptible_wait_for_termination):
20221 Move after wait_for_termination_1.
20223 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
20225 * sysdep.c (interruptible_wait_for_termination): New function
20226 which is like wait_for_termination, but allows keyboard
20229 * callproc.c (Fcall_process): Add (:file "file") as an option for
20231 (Fcall_process_region): Ditto.
20233 2011-04-30 Eli Zaretskii <eliz@gnu.org>
20235 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
20236 rather than `XVECTOR (FOO)->size'.
20238 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
20239 inttypes.h, as a gnulib replacement is used if it not available in
20242 2011-04-21 Eli Zaretskii <eliz@gnu.org>
20244 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
20245 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
20246 of MOST_POSITIVE_FIXNUM. (Bug#8528)
20248 * coding.c (coding_alloc_by_realloc): Error out if destination
20249 will grow beyond MOST_POSITIVE_FIXNUM.
20250 (decode_coding_emacs_mule): Abort if there isn't enough place in
20251 charbuf for the composition carryover bytes. Reserve an extra
20252 space for up to 2 characters produced in a loop.
20253 (decode_coding_iso_2022): Abort if there isn't enough place in
20254 charbuf for the composition carryover bytes.
20256 2011-04-21 Eli Zaretskii <eliz@gnu.org>
20258 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
20259 aborting when %lld or %lll format is passed.
20260 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
20261 %llo or %llx format is passed. (Bug#8545)
20263 * window.c (window_scroll_line_based): Use a marker instead of
20264 simple variables to record original value of point. (Bug#7952)
20266 * doprnt.c (doprnt): Fix the case where a multibyte sequence
20267 produced by %s or %c overflows available buffer space. (Bug#8545)
20269 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
20271 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
20272 (SIZE_MAX): Move defn after all includes, as they might #define it.
20274 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
20276 * w32.c (init_environment): Warn about defaulting HOME to C:\.
20278 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
20280 * keyboard.c (Qdelayed_warnings_hook): Define.
20281 (command_loop_1): Run `delayed-warnings-hook'
20282 if Vdelayed_warnings_list is non-nil.
20283 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
20284 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
20286 2011-04-28 Eli Zaretskii <eliz@gnu.org>
20288 * doprnt.c (doprnt): Don't return value smaller than the buffer
20289 size if the message was truncated. (Bug#8545).
20291 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
20293 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
20294 (Fx_window_property): #if-0 the whole functions, not just the bodies.
20296 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
20298 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
20300 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
20302 * makefile.w32-in: Update dependencies.
20304 2011-04-27 Eli Zaretskii <eliz@gnu.org>
20306 Improve `doprnt' and its usage. (Bug#8545)
20307 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
20308 `format_end'. Remove support for %l as a conversion specifier.
20309 Don't use xrealloc. Improve diagnostics when the %l size modifier
20310 is used. Update the commentary.
20312 * eval.c (verror): Simplify calculation of size_t.
20314 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
20317 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
20319 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
20322 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
20324 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
20325 This makes this file independent of the recent pseudovector change.
20327 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
20329 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
20331 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
20332 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
20333 Remove unused local.
20334 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
20336 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
20337 GCC 4.6.0 optimizes based on type-based alias analysis.
20338 For example, if b is of type struct buffer * and v of type struct
20339 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
20340 != &v->size, and therefore "v->size = 1; b->size = 2; return
20341 v->size;" must therefore return 1. This assumption is incorrect
20342 for Emacs, since it type-puns struct Lisp_Vector * with many other
20343 types. To fix this problem, this patch adds a new type struct
20344 vectorlike_header that documents the constraints on layout of vectors
20345 and pseudovectors, and helps optimizing compilers not get fooled
20346 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
20347 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
20348 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
20350 (XSETPVECTYPE): Rewrite in terms of new macro.
20351 (XSETPVECTYPESIZE): New macro, specifying both type and size.
20352 This is a bit clearer, and further avoids the possibility of
20353 undesirable aliasing.
20354 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
20355 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
20356 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
20357 since Lisp_Subr is a special case (no "next" field).
20358 (ASIZE): Now uses header.size rather than size.
20359 All previous uses of XVECTOR (foo)->size replaced to use this macro,
20360 to avoid the hassle of writing XVECTOR (foo)->header.size.
20361 (struct vectorlike_header): New type.
20362 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
20363 object, to help avoid aliasing.
20364 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
20365 (SUBRP): Likewise, since Lisp_Subr is a special case.
20366 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
20367 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
20368 (struct Lisp_Hash_Table): Combine first two members into a single
20369 struct vectorlike_header member. All uses of "size" and "next" members
20370 changed to be "header.size" and "header.next".
20371 * buffer.h (struct buffer): Likewise.
20372 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
20373 * frame.h (struct frame): Likewise.
20374 * process.h (struct Lisp_Process): Likewise.
20375 * termhooks.h (struct terminal): Likewise.
20376 * window.c (struct save_window_data, struct saved_window): Likewise.
20377 * window.h (struct window): Likewise.
20378 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
20379 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
20380 * buffer.c (init_buffer_once): Likewise.
20381 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
20383 * process.c (Fformat_network_address): Use local var for size,
20386 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
20388 Make the Lisp reader and string-to-float more consistent (Bug#8525)
20389 * data.c (atof): Remove decl; no longer used or needed.
20390 (digit_to_number): Move to lread.c.
20391 (Fstring_to_number): Use new string_to_number function, to be
20392 consistent with how the Lisp reader treats infinities and NaNs.
20393 Do not assume that floating-point numbers represent EMACS_INT
20394 without losing information; this is not true on most 64-bit hosts.
20395 Avoid double-rounding errors, by insisting on integers when
20396 parsing non-base-10 numbers, as the documentation specifies.
20397 * lisp.h (string_to_number): New decl, replacing ...
20398 (isfloat_string): Remove.
20399 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
20400 (read1): Do not accept +. and -. as integers; this
20401 appears to have been a coding error. Similarly, do not accept
20402 strings like +-1e0 as floating point numbers. Do not report
20403 overflow for integer overflows unless the base is not 10 which
20404 means we have no simple and reliable way to continue.
20405 Break out the floating-point parsing into a new
20406 function string_to_number, so that Fstring_to_number parses
20407 floating point numbers consistently with the Lisp reader.
20408 (digit_to_number): Move here from data.c. Make it static inline.
20409 (E_CHAR, EXP_INT): Remove, replacing with ...
20410 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
20411 (string_to_number): New function, replacing isfloat_string.
20412 This function checks for valid syntax and produces the resulting
20413 Lisp float number too. Rework it so that string-to-number
20414 no longer mishandles examples like "1.0e+". Use strtoumax,
20415 so that overflow for non-base-10 numbers is reported only when
20416 there's no portable and simple way to convert to floating point.
20418 * textprop.c (set_text_properties_1): Rewrite for clarity,
20419 and to avoid GCC warning about integer overflow.
20421 * intervals.h (struct interval): Use EMACS_INT for members
20422 where EMACS_UINT might cause problems. See
20423 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
20424 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
20425 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
20427 (offset_intervals): Tell GCC not to worry about length overflow
20428 when negating a negative length.
20430 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
20431 (overrun_check_free): Likewise.
20433 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
20434 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
20437 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
20438 (gnutls_make_error): Rename local to avoid shadowing.
20439 (gnutls_emacs_global_deinit): ifdef out; not used.
20440 (Fgnutls_boot): Use const for pointer to readonly storage.
20441 Comment out unused local. Fix pointer signedness problems.
20443 * lread.c (openp): Don't stuff size_t into an 'int'.
20444 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
20445 about possible signed overflow.
20447 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
20448 (GDK_KEY_g): Don't define if already defined.
20449 (xg_prepare_tooltip): Avoid pointer signedness problem.
20450 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
20452 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
20453 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
20455 * xfns.c (Fx_window_property): Simplify a bit,
20456 to make a bit faster and to avoid GCC 4.6.0 warning.
20457 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
20459 * fns.c (internal_equal): Don't assume size_t fits in int.
20461 * alloc.c (compact_small_strings): Tighten assertion a little.
20463 Replace pEd with more-general pI, and fix some printf arg casts.
20464 * lisp.h (pI): New macro, generalizing old pEd macro to other
20465 conversion specifiers. For example, use "...%"pI"d..." rather
20466 than "...%"pEd"...".
20467 (pEd): Remove. All uses replaced with similar uses of pI.
20468 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
20469 * alloc.c (check_pure_size): Don't overflow by converting size to int.
20470 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
20471 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
20472 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
20473 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
20474 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
20476 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
20477 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
20478 * print.c (safe_debug_print, print_object): Likewise.
20479 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
20481 Use pI instead of if-then-else-abort. Use %p to avoid casts,
20482 avoiding the 0 flag, which is not portable.
20483 * process.c (Fmake_network_process): Use pI to avoid cast.
20484 * region-cache.c (pp_cache): Likewise.
20485 * xdisp.c (decode_mode_spec): Likewise.
20486 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
20487 behavior on 64-bit hosts with printf arg.
20488 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
20489 (x_stop_queuing_selection_requests): Likewise.
20490 (x_get_window_property): Don't truncate byte count to an 'int'
20493 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
20494 here, since it parses constructs like leading '-' and spaces,
20495 which are not wanted; and it overflows with large numbers.
20496 Instead, simply match F[0-9]+, which is what is wanted anyway.
20498 * alloc.c: Remove unportable assumptions about struct layout.
20499 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
20500 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
20501 (allocate_vectorlike, make_pure_vector): Use the new macros,
20502 plus offsetof, to remove unportable assumptions about struct layout.
20503 These assumptions hold on all porting targets that I know of, but
20504 they are not guaranteed, they're easy to remove, and removing them
20505 makes further changes easier.
20507 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
20508 This doesn't fix a bug but makes the code clearer.
20509 (string_overrun_cookie): Now const. Use initializers that
20510 don't formally overflow signed char, to avoid warnings.
20511 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
20512 can cause Emacs to crash when string overrun checking is enabled.
20513 (allocate_buffer): Don't assume sizeof (struct buffer) is a
20514 multiple of sizeof (EMACS_INT); it need not be, if
20515 alignof(EMACS_INT) < sizeof (EMACS_INT).
20516 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
20518 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

20545 2011-04-25 Eli Zaretskii <eliz@gnu.org>
20547 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
20548 "cast to pointer from integer of different size".
20550 Improve doprnt and its use in verror. (Bug#8545)
20551 * doprnt.c (doprnt): Document the set of format control sequences
20552 supported by the function. Use SAFE_ALLOCA instead of always
20555 * eval.c (verror): Don't limit the buffer size at size_max-1, that
20556 is one byte too soon. Don't use xrealloc; instead xfree and
20559 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
20561 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
20564 * gnutls.c: Renamed global_initialized to
20565 gnutls_global_initialized. Added internals for the
20566 :verify-hostname-error, :verify-error, and :verify-flags
20567 parameters of `gnutls-boot' and documented those parameters in the
20568 docstring. Start callback support.
20569 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
20570 unless a fatal error occurred. Call gnutls_alert_send_appropriate

20646 Many local variables are now size_t instead of int or unsigned.
20647 Improve overflow protection. Support `l' modifier for integer
20648 conversions. Support %l conversion. Don't assume an EMACS_INT
20649 argument for integer conversions and for %c.
20651 * lisp.h (doprnt): Restore prototype.
20653 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on

20668 * callint.c (Fcall_interactively): When displaying error message
20669 about invalid control letter, pass the character's codepoint, not

20674 codepoint of an invalid character, to avoid displaying a bogus
20677 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
20678 `error', not SYMBOL_NAME itself.
20680 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
20681 character arguments to `error'.
20683 * charset.c (check_iso_charset_parameter): Fix incorrect argument

20756 * dispextern.h (struct redisplay_interface): Rename param
20757 to avoid shadowing.
20758 * termhooks.h (struct terminal): Likewise.

20877 deallocate memory blocks that were allocated by xmalloc (via
20878 xstrdup). This caused Emacs to crash when compiled with
20879 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
20880 --enable-checking=xmallocoverrun). xfree is now used to
20881 deallocate these memory blocks.

21295 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
21296 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
21297 Remove decls, since these functions are now static.
21298 (Funintern, Fget_internal_run_time): New decls, since these functions
21299 were already external.
21301 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:

21309 Mark functions with DEFUE instead of DEFUN,
21310 if they are used in other modules.
21311 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
21312 decls for now-static functions.
21313 * buffer.h (Fdelete_overlay): Remove decl.
21314 * callproc.c (Fgetenv_internal): Mark as internal.

21349 2011-04-13 Eli Zaretskii <eliz@gnu.org>
21351 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
21352 when at ZV. (Bug#8487)
21354 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
21356 * charset.c (Fclear_charset_maps): Use xfree instead of free.
21358 * keyboard.c (parse_tool_bar_item): Likewise.
21359 * sound.c (sound_cleanup, alsa_close): Likewise.
21360 * termcap.c (tgetent): Likewise.

21362 * xsettings.c (read_and_apply_settings): Likewise.
21364 * alloc.c (overrun_check_malloc, overrun_check_realloc)
21365 (overrun_check_free): Protoize.
21367 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
21369 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
21370 since callers should never pass a negative size.
21371 Change the signature to match that of plain 'read' and 'write'; see
21372 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
21373 * lisp.h: Update prototypes of emacs_write and emacs_read.
21375 2011-04-11 Eli Zaretskii <eliz@gnu.org>
21377 * xdisp.c (redisplay_window): Don't try to determine the character
21378 position of the scroll margin if the window start point w->startp
21379 is outside the buffer's accessible region. (Bug#8468)
21381 2011-04-10 Eli Zaretskii <eliz@gnu.org>
21383 Fix write-region and its subroutines for buffers > 2GB.
21384 * fileio.c (a_write, e_write): Modify declaration of arguments and
21385 local variables to support buffers larger than 2GB.
21386 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
21388 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
21389 argument, local variables, and return value.
21391 * lisp.h: Update prototypes of emacs_write and emacs_read.
21393 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
21395 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
21397 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
21399 Fix more problems found by GCC 4.6.0's static checks.
21401 * xdisp.c (vmessage): Use a better test for character truncation.
21403 * charset.c (load_charset_map): <, not <=, for optimization,
21404 and to avoid potential problems with integer overflow.
21405 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
21406 * casetab.c (set_identity, shuffle): Likewise.
21407 * editfns.c (Fformat): Likewise.
21408 * syntax.c (skip_chars): Likewise.
21410 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
21411 This also lets GCC 4.6.0 generate slightly better loop code.
21413 * callint.c (Fcall_interactively): <, not <=, for optimization.
21414 (Fcall_interactively): Count the number of arguments produced,
21415 not the number of arguments given. This is simpler and lets GCC
21416 4.6.0 generate slightly better code.
21418 * ftfont.c: Distingish more carefully between FcChar8 and char.
21419 The previous code passed unsigned char * to a functions like
21420 strlen and xstrcasecmp that expect char *, which does not
21421 conform to the C standard.
21422 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
21423 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
21424 char * when the C standard requires it.
21426 * keyboard.c (read_char): Remove unused var.
21428 * eval.c: Port to Windows vsnprintf (Bug#8435).
21429 Include <limits.h>.
21430 (SIZE_MAX): Define if the headers do not.
21431 (verror): Do not give up if vsnprintf returns a negative count.
21432 Instead, grow the buffer. This ports to Windows vsnprintf, which
21433 does not conform to C99. Problem reported by Eli Zaretskii.
21434 Also, simplify the allocation scheme, by avoiding the need for
21435 calling realloc, and removing the ALLOCATED variable.
21437 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
21439 Remove invocations of doprnt, as Emacs now uses vsnprintf.
21440 But keep the doprint source code for now, as we might revamp it
21441 and use it again (Bug#8435).
21442 * lisp.h (doprnt): Remove.
21443 * Makefile.in (base_obj): Remove doprnt.o.
21444 * deps.mk (doprnt.o): Remove.
21446 error: Print 32- and 64-bit integers portably (Bug#8435).
21447 Without this change, on typical 64-bit hosts error ("...%d...", N)
21448 was used to print both 32- and 64-bit integers N, which relied on
21449 undefined behavior.
21450 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
21451 * lisp.h (error, verror): Mark as printf-like functions.
21452 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
21453 Report overflow in size calculations when allocating printf buffer.
21454 Do not truncate output string at its first null byte.
21455 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
21456 Truncate the output at a character boundary, since vsnprintf does not
21458 * charset.c (check_iso_charset_parameter): Convert internal
21459 character to string before calling 'error', since %c now has the
21461 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
21462 overflow when computing char to be passed to 'error'. Do not
21463 pass Lisp_Object to 'error'; pass the integer instead.
21464 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
21465 formatted with plain %d.
21467 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
21469 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
21471 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
21473 * xterm.c (x_catch_errors): Remove duplicate declaration.
21475 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
21477 * xdisp.c, lisp.h (message_nolog): Remove; unused.
21479 2011-04-10 Jim Meyering <meyering@redhat.com>
21481 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
21482 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
21483 return ssize_t not "int", and use size_t as the buffer length.
21484 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
21485 * gnutls.h: Update declarations.
21486 * process.c (read_process_output): Use ssize_t, to match.
21487 (send_process): Likewise.
21489 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
21491 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
21493 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
21495 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
21496 Use unsigned char, to match FcChar8 type definition.
21498 * xterm.c (handle_one_xevent):
21499 * xmenu.c (create_and_show_popup_menu):
21500 * xselect.c (x_decline_selection_request)
21501 (x_reply_selection_request): Avoid type-punned deref of X events.
21503 2011-04-09 Eli Zaretskii <eliz@gnu.org>
21505 Fix some uses of `int' instead of EMACS_INT.
21506 * search.c (string_match_1, fast_string_match)
21507 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
21508 (scan_buffer, find_next_newline_no_quit)
21509 (find_before_next_newline, search_command, Freplace_match)
21510 (Fmatch_data): Make some `int' variables be EMACS_INT.
21512 * xdisp.c (display_count_lines): 3rd argument and return value now
21513 EMACS_INT. All callers changed.
21514 (pint2hrstr): Last argument is now EMACS_INT.
21516 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
21517 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)

21529 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
21530 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
21532 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
21533 (encode_invocation_designation): Last argument P_NCHARS is now
21535 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
21536 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
21538 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
21541 * ccl.c (Fccl_execute_on_string): Declare some variables
21544 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
21546 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
21548 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
21550 * process.c (Fformat_network_address): Doc fix.
21552 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
21554 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
21556 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
21558 * keyboard.c (read_char): Call Lisp function help-form-show,
21559 instead of using internal_with_output_to_temp_buffer.
21560 (Qhelp_form_show): New var.
21561 (syms_of_keyboard): Use DEFSYM macro.
21563 * print.c (internal_with_output_to_temp_buffer): Function deleted.
21565 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
21567 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
21569 * process.c (Flist_processes): Remove to Lisp.

21574 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
21576 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
21578 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
21580 Fix more problems found by GCC 4.6.0's static checks.

21584 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
21586 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
21588 * xdisp.c (vmessage): Mark as a printf-like function.
21590 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
21592 * sound.c (sound_warning): Don't crash if arg contains a printf format.
21594 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
21595 printf-like functions.
21596 (tiff_load): Add casts to remove these marks before passing them
21597 to system-supplied API.
21599 * eval.c (Fsignal): Remove excess argument to 'fatal'.
21601 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
21602 This avoids several warnings with gcc -Wstrict-overflow.
21603 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
21604 directly, rather than having caller test rule sign. This avoids
21605 some unnecessary tests.
21606 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
21607 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
21608 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
21610 * xfont.c (xfont_text_extents): Remove var that was set but not used.
21611 (xfont_open): Avoid unnecessary tests.
21613 * composite.c (composition_gstring_put_cache): Use unsigned integer.
21615 * composite.h, composite.c (composition_gstring_put_cache):
21616 Use EMACS_INT, not int, for length.

21622 by using the new macro.
21624 * textprop.c (set_text_properties_1): Change while to do-while,
21625 since the condition is always true at first.
21627 * intervals.c (graft_intervals_into_buffer): Mark var as used.
21628 (interval_deletion_adjustment): Return unsigned value.
21631 * process.c (list_processes_1, create_pty, read_process_output):

21643 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
21644 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
21645 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
21647 * print.c (print_error_message): Avoid int overflow.
21649 * font.c (font_list_entities): Redo for clarity,
21650 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
21652 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
21653 (font_score): Avoid potential overflow in diff calculation.
21655 * fns.c (substring_both): Remove var that is set but not used.
21656 (sxhash): Redo loop for clarity and to avoid wraparound warning.
21658 * eval.c (funcall_lambda): Rename local to avoid shadowing.
21660 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
21661 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
21662 can always succeed if overflow has undefined behavior.
21664 * search.c (boyer_moore, wordify): Remove vars set but not used.
21665 (wordify): Omit three unnecessary tests.
21667 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
21668 All callers changed. This avoids the need for an unused var.
21670 * casefiddle.c (casify_region): Remove var that is set but not used.
21672 * dired.c (file_name_completion): Remove var that is set but not used.
21674 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
21676 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
21677 (Finsert_file_contents): Remove unnecessary code checking fd.
21679 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
21680 Check for integer overflow on size calculations.
21682 * buffer.c (Fprevious_overlay_change): Remove var that is set
21685 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
21686 Remove vars that are set but not used.
21687 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
21688 (timer_check_2): Mark vars as initialized.
21690 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
21692 * image.c (lookup_image): Remove var that is set but not used.
21693 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
21695 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
21696 that are set but not used.
21698 * xfns.c (make_invisible_cursor): Don't return garbage
21699 if XCreateBitmapFromData fails (Bug#8410).
21701 * xselect.c (x_get_local_selection, x_handle_property_notify):
21702 Remove vars that are set but not used.
21704 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
21705 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
21707 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
21708 Remove var that is set but not used.

21710 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
21711 Check for overflow.
21713 * xfaces.c (realize_named_face): Remove vars that are set but not used.
21714 (map_tty_color) [!defined MSDOS]: Likewise.
21716 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
21718 * coding.c: Remove vars that are set but not used.
21719 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
21720 All callers changed.
21721 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
21722 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
21723 (decode_coding_charset): Remove vars that are set but not used.
21725 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
21726 that is set but not used.
21728 * print.c (print_object): Remove var that is set but not used.
21730 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
21731 The gnulib version avoids calling malloc in the usual case,
21732 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
21733 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
21734 * filelock.c (current_lock_owner): Likewise.
21735 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
21736 * sysdep.c: Include allocator.h, careadlinkat.h.
21737 (emacs_no_realloc_allocator): New static constant.

21767 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
21768 (ns_get_family): Likewise.
21770 2011-04-02 Juanma Barranquero <lekktu@gmail.com>

21776 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
21779 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
21781 Add lexical binding.

21792 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
21794 (syms_of_lread): Declare `lexical-binding'.
21796 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
21798 * keyboard.c (eval_dyn): New fun.
21799 (menu_item_eval_property): Use it.
21801 * image.c (parse_image_spec): Use Ffunctionp.
21803 * fns.c (concat, mapcar1): Accept byte-code-functions.
21805 * eval.c (Fsetq): Handle lexical vars.
21806 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
21807 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
21808 (FletX, Flet): Obey lexical binding.
21809 (Fcommandp): Handle closures.
21810 (Feval): New `lexical' arg.
21811 (eval_sub): New function extracted from Feval. Use it almost
21812 everywhere where Feval was used. Look up vars in lexical env.
21814 (Ffunctionp): Move from subr.el.
21815 (Ffuncall): Handle closures.
21816 (apply_lambda): Remove `eval_flags'.
21817 (funcall_lambda): Handle closures and new byte-code-functions.
21818 (Fspecial_variable_p): New function.
21819 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
21820 but without exporting it to Lisp.
21822 * doc.c (Fdocumentation, store_function_docstring):
21823 * data.c (Finteractive_form): Handle closures.
21825 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
21828 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
21830 (exec_byte_code): New function extracted from Fbyte_code to handle new
21831 calling convention for byte-code-functions. Add new byte-codes.
21833 * buffer.c (defvar_per_buffer): Set new `declared_special' field.

21839 * xdisp.c (redisplay_internal): Fix prototype.
21841 2011-03-31 Eli Zaretskii <eliz@gnu.org>
21843 * xdisp.c (SCROLL_LIMIT): New macro.
21844 (try_scrolling): Use it when setting scroll_limit.
21845 Limit scrolling to 100 screen lines.
21846 (redisplay_window): Even when falling back on "recentering",
21847 position point in the window according to scroll-conservatively,
21848 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
21850 (try_scrolling): When point is above the window, allow searching
21851 as far as scroll_max, or one screenful, to compute vertical
21852 distance from PT to the scroll margin position. This prevents
21853 try_scrolling from unnecessarily failing when
21854 scroll-conservatively is set to a value slightly larger than the
21855 window height. Clean up the case of PT below the margin at bottom
21856 of window: scroll_max can no longer be INT_MAX. When aggressive
21857 scrolling is in use, don't let point enter the opposite scroll
21858 margin as result of the scroll.
21859 (syms_of_xdisp) <scroll-conservatively>: Document the
21860 threshold of 100 lines for never-recentering scrolling.
21862 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
21864 * dispextern.h (move_it_by_lines):

21868 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
21869 (redisplay_internal): Remove parameter `preserve_echo_area',
21870 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
21872 * indent.c (Fvertical_motion):
21873 * window.c (window_scroll_pixel_based, Frecenter):
21874 Don't pass `need_y_p' to `move_it_by_lines'.
21876 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
21878 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
21879 steal a few bits to be more compact.
21880 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
21881 Remove unneeded casts.
21883 * bytecode.c (Fbyte_code): CAR and CDR can GC.
21885 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
21887 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
21888 binding" message (bug#7967).
21890 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
21892 Fix more problems found by GCC 4.6.0's static checks.
21894 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
21895 Remove unused local var.
21897 * editfns.c (Fmessage_box): Remove unused local var.
21899 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
21900 (note_mode_line_or_margin_highlight, note_mouse_highlight):
21901 Omit unused local vars.
21902 * window.c (shrink_windows): Omit unused local var.
21903 * menu.c (digest_single_submenu): Omit unused local var.
21904 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
21905 Omit unused local var.
21907 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
21908 Don't assume string length fits in int.
21909 (keyremap_step, read_key_sequence): Use size_t for sizes.
21910 (read_key_sequence): Don't check last_real_key_start redundantly.
21912 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
21913 instead of alloca (Bug#8344).
21915 * eval.c (Fbacktrace): Don't assume nargs fits in int.
21916 (Fbacktrace_frame): Don't assume nframes fits in int.
21918 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.

21925 * cm.c (calccost): Turn while-do into do-while, for clarity.
21927 * keyboard.c (syms_of_keyboard): Use the same style as later
21928 in this function when indexing through an array. This also
21929 works around GCC bug 48267.
21931 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
21933 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
21935 * chartab.c (sub_char_table_ref_and_range): Redo for slight
21936 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
21938 * keyboard.c, keyboard.h (num_input_events): Now size_t.
21939 This avoids undefined behavior on integer overflow, and is a bit
21940 more convenient anyway since it is compared to a size_t variable.
21942 Variadic C functions now count arguments with size_t, not int.
21943 This avoids an unnecessary limitation on 64-bit machines, which
21944 caused (substring ...) to crash on large vectors (Bug#8344).

21954 * fns.c (concat): Likewise.
21955 * frame.c (x_set_frame_parameters): Likewise.
21956 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
21957 0 if not found, not -1. All callers changed.
21959 * alloc.c (garbage_collect): Don't assume stack size fits in int.
21960 (stack_copy_size): Now size_t, not int.
21961 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
21963 2011-03-28 Juanma Barranquero <lekktu@gmail.com>

21982 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
21983 don't set the hook to nil, but remove the offending function instead.
21984 (Qcommand_hook_internal): Remove, unused.
21985 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
21986 Vcommand_hook_internal.
21988 * eval.c (enum run_hooks_condition): Remove.
21989 (funcall_nil, funcall_not): New functions.
21990 (run_hook_with_args): Call each function through a `funcall' argument.

22176 * coding.c (encode_coding_raw_text): Avoid unnecessary test
22177 the first time through the loop, since we know p0 < p1 then.
22178 This also avoids a gcc -Wstrict-overflow warning.
22180 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
22181 leading to a memory leak, possible in functions like
22182 load_charset_map_from_file that can allocate an unbounded number
22183 of objects (Bug#8318).
22185 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
22186 that could (at least in theory) be that large.
22188 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
22189 This is less likely to overflow, and avoids undefined behavior if
22190 overflow does occur. All callers changed. Use strtoul to scan
22191 for the unsigned long integer.
22192 (pint2hrstr): Simplify and tune code slightly.
22193 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
22195 * scroll.c (do_scrolling): Work around GCC bug 48228.
22196 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
22198 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
22199 This also avoids a warning with gcc -Wstrict-overflow.
22200 (validate_x_resource_name): Simplify count usage.
22201 This also avoids a warning with gcc -Wstrict-overflow.
22203 * fileio.c (Fcopy_file): Report error if fchown or fchmod
22206 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
22208 * process.c (Fmake_network_process): Use socklen_t, not int,
22209 where POSIX says socklen_t is required in portable programs.
22210 This fixes a porting bug on hosts like 64-bit HP-UX, where
22211 socklen_t is wider than int (Bug#8277).
22212 (Fmake_network_process, server_accept_connection):
22213 (wait_reading_process_output, read_process_output):
22216 * process.c: Rename or move locals to avoid shadowing.

22218 (read_process_output_error_handler, exec_sentinel_error_handler):
22219 Rename or move locals.
22220 (Fmake_network_process): Define label "retry_connect" only if needed.
22221 (Fnetwork_interface_info): Fix pointer signedness.
22222 (process_send_signal): Add cast to avoid pointer signedness problem.
22223 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
22224 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
22226 Make tparam.h and terminfo.c consistent.
22227 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
22228 Include tparam.h instead, since it declares them.
22229 * cm.h (PC): Remove extern decl; tparam.h now does this.
22230 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
22231 * terminfo.c: Include tparam.h, to check interfaces.
22232 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
22233 (tparam): Adjust signature to match interface in tparam.h;
22234 this removes some undefined behavior. Check that outstring and len
22235 are zero, which they always are with Emacs.
22236 * tparam.h (PC, BC, UP): New extern decls.
22238 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
22239 (xftfont_open): Rename locals to avoid shadowing.
22241 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.

22243 (OTF_TAG_SYM): Omit macro if not needed.
22244 (ftfont_list): Remove unused local.
22245 (get_adstyle_property, ftfont_pattern_entity):
22246 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):

22251 * xml.c (make_dom): Now static.
22253 * composite.c (composition_compute_stop_pos): Rename local to
22255 (composition_reseat_it): Remove unused locals.
22256 (find_automatic_composition, composition_adjust_point): Likewise.
22257 (composition_update_it): Mark var as initialized.
22258 (find_automatic_composition): Mark vars as initialized,
22259 with a FIXME (Bug#8290).

22262 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
22263 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
22264 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
22265 (BUF_DEC_POS): Be more systematic about renaming local temporaries
22266 to avoid shadowing.
22268 * textprop.c (property_change_between_p): Remove; unused.
22270 * intervals.c (interval_start_pos): Now static.
22272 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

22275 Rename locals to avoid shadowing.
22277 * sound.c (wav_play, au_play, Fplay_sound_internal):
22278 Fix pointer signedness.
22279 (alsa_choose_format): Remove unused local var.
22280 (wav_play): Initialize a variable to 0, to prevent undefined
22281 behavior (Bug#8278).
22283 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
22285 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
22287 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
22288 clobbering (Bug#8298).
22289 * sysdep.c (sys_subshell): Likewise.
22290 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
22292 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
22293 This should get cleaned up, so that child_setup has the
22294 same signature on all platforms.
22296 * callproc.c (call_process_cleanup): Now static.
22297 (relocate_fd): Rename locals to avoid shadowing.
22299 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
22301 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
22302 not to be necessary, and produces flickering.
22304 2011-03-20 Glenn Morris <rgm@gnu.org>
22306 * config.in: Remove file.
22308 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
22310 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
22311 are now in src/globals.h.
22312 (syms_of_minibuf): Remove spurious & from previous change.
22314 2011-03-20 Leo Liu <sdl.web@gmail.com>
22316 * minibuf.c (completing-read-function): New variable.
22317 (completing-read-default): Rename from completing-read.
22318 (completing-read): Call completing-read-function.
22320 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
22322 * xfaces.c (Fx_load_color_file):
22323 Read color file from absolute filename (bug#8250).
22325 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
22327 * makefile.w32-in: Update dependencies.
22329 2011-03-17 Eli Zaretskii <eliz@gnu.org>
22331 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.

22338 (sigchld_handler): Now static.
22340 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.

22351 (CONSTANTLIM): Remove; unused.
22352 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
22353 Define only if needed.
22355 * unexelf.c (unexec): Name an expression,
22356 to avoid gcc -Wbad-function-cast warning.
22357 Use a different way to cause a compilation error if anyone uses
22358 n rather than nn, a way that does not involve shadowing.
22359 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
22361 * deps.mk (unexalpha.o): Remove; unused.
22363 New file unexec.h, the (simple) interface for unexec (Bug#8267).
22364 * unexec.h: New file.
22365 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
22366 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
22367 Depend on unexec.h.
22368 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
22369 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
22370 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.
22371 Change as necessary to match prototype in unexec.h.

22418 * callint.c (quotify_arg, quotify_args): Now static.
22419 (Fcall_interactively): Rename locals to avoid shadowing.
22420 Use const pointer when appropriate.
22422 * lisp.h (get_system_name, get_operating_system_release):

22424 * process.c (get_operating_system_release): Move decl to lisp.h.
22425 * xrdb.c (get_system_name): Likewise.
22426 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
22427 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
22428 some of which prompt warnings from gcc -Wbad-function-cast.
22429 (Fformat_time_string, Fencode_time, Finsert_char):
22430 (Ftranslate_region_internal, Fformat):
22431 Rename or remove local vars to avoid shadowing.

22456 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
22457 (GC_STRING_CHARS): Remove; not used.
22458 (Fmemory_limit): Cast sbrk's returned value to char *.
22460 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
22461 avoids undefined behavior in theory.
22463 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
22465 Use functions, not macros, for up- and down-casing (Bug#8254).
22466 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
22467 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
22468 to use the following functions instead of these macros.
22469 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
22470 EMACS_INT, since callers assume the returned value fits in int.
22471 (upcase1): Likewise, for UPCASE_TABLE.
22472 (uppercasep, lowercasep, upcase): New static inline functions.
22473 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

22482 which gcc can warn about.
22483 (regex_compile, re_match_2_internal): Mark locals as initialized.
22484 (RETALLOC_IF): Define only if needed.
22485 (WORDCHAR_P): Likewise. This one is never needed, but is used
22486 only in a comment talking about a compiler bug, so put inside
22487 the #if 0 of that comment.
22488 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
22489 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
22492 * search.c (boyer_moore): Rename locals to avoid shadowing.
22493 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):

22506 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
22507 Rename locals to avoid shadowing.
22508 (Fvertical_motion): Mark locals as initialized.
22510 * casefiddle.c (casify_object, casify_region): Now static.
22511 (casify_region): Mark local as initialized.
22513 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
22515 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
22516 New macros, so that the caller can use some names other than
22517 gcpro1, gcpro2, etc.
22518 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
22520 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
22521 argument, for consistency with GCPRO2_VAR, etc: it is now the
22522 prefix of the variable, not the variable itself. All uses
22524 * dired.c (directory_files_internal, file_name_completion):
22525 Rename locals to avoid shadowing.
22527 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
22528 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
22529 dired.c's scmp function, had undefined behavior.
22530 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
22531 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
22532 * buffer.h: ... to here, because these macros use current_buffer,
22533 and the new implementation with inline functions needs to have
22534 current_buffer in scope now, rather than later when the macros
22536 (downcase, upcase1): New static inline functions.
22537 (DOWNCASE, UPCASE1): Reimplement using these functions.
22538 This avoids undefined behavior in expressions like
22539 DOWNCASE (x) == DOWNCASE (y), which previously suffered
22540 from race conditions in accessing the global variables
22541 case_temp1 and case_temp2.
22542 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
22543 * lisp.h (case_temp1, case_temp2): Remove their decls.
22544 * character.h (ASCII_CHAR_P): Move from here ...
22545 * lisp.h: ... to here, so that the inline functions mentioned
22546 above can use them.
22548 * dired.c (directory_files_internal_unwind): Now static.
22550 * fileio.c (file_name_as_directory, directory_file_name):
22551 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
22553 (file_name_as_directory): Use const pointers when appropriate.
22554 (Fexpand_file_name): Likewise. In particular, newdir might
22555 point at constant storage, so make it a const pointer.
22556 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
22557 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
22559 (Fset_file_times, Finsert_file_contents, auto_save_error):
22560 Rename locals to avoid shadowing.

22564 to avoid shadowing.
22566 * marker.c (bytepos_to_charpos): Remove; unused.
22568 * lisp.h (verify_bytepos, count_markers): New decls,
22569 so that gcc does not warn that these functions aren't declared.
22571 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
22572 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
22573 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
22574 (copy_text): Remove unused local var.
22576 * filelock.c (within_one_second): Now static.
22577 (lock_file_1): Rename local to avoid shadowing.
22579 * buffer.c (fix_overlays_before): Mark locals as initialized.
22580 (fix_start_end_in_overlays): Likewise. This function should be
22581 simplified by using pointers-to-pointers, but that's a different
22583 (switch_to_buffer_1): Now static.
22584 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
22585 (report_overlay_modification): Rename locals to avoid shadowing.
22587 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
22588 Fix pointer signedness issue.
22589 (sys_subshell): Mark local as volatile if checking for lint,
22590 to suppress a gcc -Wclobbered warning that does not seem to be right.
22591 (MAXPATHLEN): Define only if needed.
22593 * process.c (serial_open, serial_configure): Move decls from here ...
22594 * systty.h: ... to here, so that they can be checked.
22596 * fns.c (get_random, seed_random): Move extern decls from here ...
22597 * lisp.h: ... to here, so that they can be checked.
22599 * sysdep.c (reset_io): Now static.
22600 (wait_for_termination_signal): Remove; unused.
22602 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):

22605 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
22606 (DENSE_TABLE_SIZE): Remove; unused.
22607 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
22608 (describe_map_tree):
22609 Rename locals to avoid shadowing.
22611 * keyboard.c: Declare functions static if they are not used elsewhere.
22612 (echo_char, echo_dash, cmd_error, top_level_2):
22613 (poll_for_input, handle_async_input): Now static.
22614 (read_char, kbd_buffer_get_event, make_lispy_position):
22615 (make_lispy_event, make_lispy_movement, apply_modifiers):
22616 (decode_keyboard_code, tty_read_avail_input, menu_bar_items):
22617 (parse_tool_bar_item, read_key_sequence, Fread_key_sequence):
22618 (Fread_key_sequence_vector): Rename locals to avoid shadowing.
22619 (read_key_sequence, read_char): Mark locals as initialized.
