246 Use bool for boolean.
247 * keyboard.c (timers_run, swallow_events)
248 (detect_input_pending_run_timers):
249 * process.c (wait_reading_process_output):
250 Use unsigned for counter where wraparound-on-overflow is desired,
251 since unsigned is guaranteed to have that behavior and signed is not.
252 (read_char): Use ptrdiff_t for string length.
253 (get_input_pending): Remove first argument, since it was always
254 the same pointer-to-int (now pointer-to-boolean) &input_pending,
255 and behave as if it had that value. Return new value of
256 input_pending. All callers changed.
257 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
258 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's

279 * termopts.h (flow_control, meta_key): Remove unused decls.
280 * dispnew.c, indent.c, nsterm.m, term.c, xsettings.c, xsmfns.c:
281 Don't include termopts.h.
283 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>

298 2012-10-09 Eli Zaretskii <eliz@gnu.org>
300 * w32fns.c (w32_last_error): Change the return value to DWORD, to
301 match what GetLastError returns. Explain why the function is
304 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
305 'is_tooltip_frame', to avoid confusion with its global namesake.
307 2012-10-08 Daniel Colascione <dancol@dancol.org>
309 * xdisp.c (start_hourglass): Call w32_note_current_window when
310 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
311 build that caused Emacs to display the hourglass cursor forever.
313 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
314 which is broken under remote desktop, calculate the number of
315 colors available for a display based on the display's number of
316 planes and number of bits per pixel per plane. (bug#10397).
318 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
320 * nsfont.m (Vfonts_in_cache): New variable.
321 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
322 are used. Add cached fonts to Vfonts_in_cache.
323 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
325 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
327 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
329 (FONT_H): Define after FRAME_H.
330 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
333 * w32term.c: Remove leftover declaration of keyboard_codepage.
335 2012-10-08 Eli Zaretskii <eliz@gnu.org>
337 * makefile.w32-in (FONT_H): Add $(FRAME_H).
338 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
339 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
340 (GLOBAL_SOURCES): Add cygw32.c.
341 ($(BLD)/unexw32.$(O)):
343 ($(BLD)/w32console.$(O)):
344 ($(BLD)/w32fns.$(O)):
345 ($(BLD)/w32heap.$(O)):
346 ($(BLD)/w32menu.$(O)):
347 ($(BLD)/w32proc.$(O)): Add w32common.h.
349 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
351 (x_to_w32_color): Don't modify the argument, modify a copy instead.
353 2012-10-08 Daniel Colascione <dancol@dancol.org>
355 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
356 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
357 accidental message numbering hole. Change other messages to
360 * w32select.h (HAVE_W32SELECT): Remove.
362 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
363 w32common.h instead of w32heap.h.
365 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
366 (get_allocation_unit, get_processor_type, get_w32_major_version)
367 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
368 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
369 (OS_NT, os_subtype, cache_system_info): Move declarations to
372 * w32heap.c: Include w32common.h.
373 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
374 (w32_minor_version, w32_build_number, w32_subtype):
375 Remove duplicate definitions.
377 * w32fns.c: Include w32common.h; include w32heap.h only in
380 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
381 Use `report_file_error' instead of `error' in order to better
382 inform users of what went wrong. Increase NTGUI_UNICODE file
383 dialog box file name length to 32k, the maximum allowed by the NT
386 * w32common.h: New file.
387 (ROUND_UP, ROUND_DOWN, get_page_size)
388 (get_allocation_unit, get_processor_type, get_w32_major_version)
389 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
390 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
391 (OS_NT, os_subtype, cache_system_info): Move here.
393 * unexw32.c, unexcw.c: Include w32common.h.
395 * emacs.c (main): Use (defined (WINDOWSNT) || defined
396 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
397 to call syms_of_w32select.
399 * cygw32.h: Remove obsolete EXFUN declarations.
401 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
403 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
404 of w32inevt.o from SOME_MACHINE_OBJECTS.
406 2012-10-08 Daniel Colascione <dancol@dancol.org>
408 * image.c: Permanent fix for JPEG compilation issue --- limit
409 jpeglib `boolean' redefinition to Cygwin builds.
411 2012-10-08 Eli Zaretskii <eliz@gnu.org>
413 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
415 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
418 2012-10-08 Daniel Colascione <dancol@dancol.org>
420 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
421 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
422 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
423 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
424 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
425 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
426 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
427 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
428 now a supported configuration.
430 * Makefile.in: consolidate image variables into LIBIMAGE; add
431 W32_OBJ and W32_LIBS. Compile new files.
434 (_DebPrint) declare tracing facility for W32 debugging. We need
435 to unify tracing later.
437 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
438 unconditional use of W32 Unicode functions. Cygwin runs only on
439 100% Unicode operating systems.
441 * cygw32.c: New file. Define Cygwin-specific facilities.
442 (Fcygwin_convert_path_to_windows)
443 (Fcygwin_convert_path_from_windows): New user functions for
444 accessing Cygwin path-munging routines.
446 * cygw32.h: New file.
447 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
448 UTF-16LE strings temporarily inside non-Lisp-visible string
451 (w32_strerror): Just what it says on the tin.
453 * emacs.c: Make the NS fork-then-exec code for daemon-launching
454 also run for Cygwin; both systems have the same problem with using
455 GUI facilities in a forked child. Also call syms_of_cygw32,
456 syms_of_w32select in correct places.
458 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
459 needs fork-then-exec for daemon launching.
461 * font.h: Include frame.h.
463 * image.c: Use the image library cache machinery only when we're
464 compiling for native WINDOWSNT; Cygwin can use shared libraries
465 like any other Unixlike system.
467 * keyboard.c: Clarify a comment regarding the input loop.
469 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
470 functions directly instead of trying to detect at runtime that our
471 host operating system supports them. We make this change for two
472 reasons: Cygwin lacks support for the multibyte character
473 conversion functions used by the legacy menu code, and Cygwin
474 never needs to rely on non-Unicode APIs.
476 * unexw32.c (hinst): Declare extern.
478 * w32.c: Change header order;
479 (w32_strerror): Move to w32fns.c because we need it for
480 non-WINDOWSNT builds.
482 * w32.h: Add #error macro to make sure we don't include w32.h for
483 Cygwin builds. Remove w32select declarations.
485 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
486 w32fns.c. w32console.c is WINDOWSNT-only.
488 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
489 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
491 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
492 (w32_major_version, w32_minor_version, w32_build_number)
493 (os_subtype, sound_type): Define here
494 (w32_defined_color): Make color parameter const for consistency
495 with other _defined_color functions.
496 (w32_createwindow): Unconditionally call w32_init_class instead of
497 doing so only when hprevinst is non-NULL. Plumbing hprevinst
498 through the code is complex and unnecessary because class
499 registration is practically free.
500 (w32_name_of_message): New EMACSDEBUG-only function.
501 (Fset_message_beep): Move here
502 (Fx_open_connection): Require that the display name for Windows be
503 "w32" for consistency, emacsclient disambiguation, and maybe, one
504 day, multi-window-system support.
505 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
506 Cygwin files for W32 GUI facilities, since these clearly don't
509 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)

521 (w32_console_toggle_lock_key): Move to w32fns.c.
523 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
525 * w32proc.c (_DebPrint): Move to w32fns.c.
526 * w32select.c: Include string.h, stdio.h for Cygwin.
527 * w32select.h: New File.
529 * w32term.c: Include io.h for non-CYGWIN builds; needed for
531 (w32_message_fd): New variable. Under Cygwin, holds the file
532 descriptor the system used to tell us about pending thread
535 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
536 that prevented compilation under non-WINDOWSNT systems.
538 (w32_initialize): Open /dev/windows and assign it to
539 w32_message_fd. Provide w32 feature.
541 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
542 (WM_EMACS_INPUT_READY): add.
543 (prepend_msg, w32_message_fd): Declare globally.
546 (keyboard_handle): Use only when WINDOWSNT.
547 (notify_msg_ready): New function. Posts a message to the main
548 thread's message queue under CYGWIN, which wakes up the main
549 thread from select(2) by making the /dev/windows file descriptor
550 ready. Under WINDOWSNT, it sets an event the same way the old
553 (post, prepend_msg): Actually call notify_msg_ready instead of
554 setting the input event directly.
556 2012-10-07 Eli Zaretskii <eliz@gnu.org>
558 * ralloc.c (relinquish): If a heap is ready to be relinquished,
559 but it still has blocs in it, don't return it to the system,
560 instead of aborting. (Bug#12402)
562 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
564 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).

597 Improve sys_siglist detection.
598 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
599 defined as a macro, as is done in Solaris.
600 (sys_siglist_entries): New macro.
601 (save_strsignal): Use it.
602 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
603 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
605 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
607 * nsfns.m (Fx_create_frame): Call x_default_parameter with
608 fullscreen/Fullscreen.

628 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
630 2012-10-05 Eli Zaretskii <eliz@gnu.org>
632 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
634 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
635 that time stamps of directories could also be changed.
636 Don't request the too broad GENERIC_WRITE, only the more restrictive
637 FILE_WRITE_ATTRIBUTES access rights.
639 * fileio.c (Fset_file_times): Special-case ignoring errors for
640 directories only on MSDOS, not on MS-Windows.
642 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
644 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
646 2012-10-04 Eli Zaretskii <eliz@gnu.org>

649 see whether CreateFile failed.
651 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
653 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
654 to avoid similar races.
655 * keyboard.c (pending_signals): Now bool, not int.
657 Port timers to OpenBSD, plus check for timer failures.
658 OpenBSD problem reported by Han Boetes.
659 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
661 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
662 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
663 like OpenBSD, which has timer_settime but does not declare it.
664 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
665 whether to use itimerspec-related primitives. All uses of
666 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
668 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
670 * profiler.c (handle_profiler_signal): Fix a malloc race
671 that caused Emacs to hang on Fedora 17 when profiling Lisp.
673 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
675 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
677 2012-10-02 Eli Zaretskii <eliz@gnu.org>
679 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
680 consistent with the change in return value of 'safe_strsignal'.
682 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
684 Prefer plain 'static' to 'static inline' (Bug#12541).
685 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
686 (bidi_set_sor_type, bidi_push_embedding_level)
687 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)

692 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
693 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
694 Now 'static', not 'static inline'.
696 Count overruns when profiling; change units to ns.
697 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
698 Give extra weight to samples after overruns, to attempt to count
699 the time more accurately.
700 (setup_cpu_timer): Change sampling interval units from ms to ns, since
701 the underlying primitives nominally do ns.
702 (Fprofiler_cpu_start): Document the change. Mention that
703 the sampling intervals are only approximate.
705 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
707 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
709 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
710 case for the special 0 coding-system.
712 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
713 (Fmake_overlay): Remove redundant tests.
714 (fix_start_end_in_overlays): Remove redundant recentering.
716 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
718 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
721 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
723 Fix a malloc race condition involving strsignal.
724 A signal can arrive in the middle of a malloc, and Emacs's signal
725 handler can invoke strsignal, which can invoke malloc, which is
726 not portable. This race condition bug makes Emacs hang on GNU/Linux.
727 Fix it by altering the signal handler so that it does not invoke
729 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
730 * process.c (status_message): Use const pointer, in case strsignal
731 is #defined to safe_strsignal.
732 * sysdep.c (sys_siglist, init_signals): Always define and
733 initialize a substitute sys_siglist if the system does not define
734 one, even if HAVE_STRSIGNAL.
735 (safe_strsignal): Rename from strsignal. Always define,
736 using sys_siglist. Return a const pointer.
737 * syssignal.h (safe_strsignal): New decl.
738 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
740 2012-10-01 Eli Zaretskii <eliz@gnu.org>
742 * w32proc.c (timer_loop): Fix code that waits for timer
743 expiration, to avoid high CPU usage.
745 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
747 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
748 (sweep_weak_table): Remove redundant prototypes.
750 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
752 * emacs.c: Move the inclusion of TERM_HEADER after including
753 windows.h on WINDOWSNT. This avoids compilation problems with
756 2012-10-01 Eli Zaretskii <eliz@gnu.org>
758 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
759 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
760 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
761 as the previous version used 'void *'.
763 * ralloc.c (ROUNDUP): Fix last change.
764 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
767 * w32proc.c <disable_itimers>: New static flag.
768 (init_timers): Initialize it to zero, after creating the critical
769 sections used by the timer threads.
770 (term_timers): Set to 1 before deleting the critical sections.
771 (getitimer, setitimer): If disable_itimers is non-zero, return an
772 error indication without doing anything. Reported by Fabrice
773 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
774 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
776 [!HAVE_SETITIMER]: Behave as the previous version that didn't
779 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
780 term_ntproc after all the other bookkeeping, to get timers working
783 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
785 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
786 Suggested by Juri Linkov in
787 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
789 Prefer plain 'static' to 'static inline' (Bug#12541).
790 With static functions, modern compilers inline pretty well by
791 themselves; advice from programmers often hurts as much as it helps.
792 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
793 this change shrinks the text size of the Emacs executable by 1.1%
794 without affecting CPU significantly in my benchmark.

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

1067 Suggested by Eli Zaretskii in
1068 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00811.html>.
1070 2012-09-30 Eli Zaretskii <eliz@gnu.org>
1072 * profiler.c (Fprofiler_cpu_stop): Use timer_settime only if
1073 HAVE_TIMER_SETTIME is defined.

1077 Profiler improvements: more-accurate timers, overflow checks.
1078 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
1079 signal.h, setjmp.h. Include systime.h instead.
1080 (saturated_add): New function.

1087 All uses changed to store the new value.
1088 (handle_profiler_signal): Rename from sigprof_handler_1,
1089 for consistency with other handlers. Do not check whether
1090 cpu_log is a hash-table if garbage collecting, since it
1091 doesn't matter in that case.

1093 for consistency with other handlers.
1094 (setup_cpu_timer): New function, with much of what used to be in
1095 Fprofiler_cpu_start. Check for out-of-range argument.
1096 Prefer timer_settime if available, and prefer
1097 thread cputime clocks, then process cputime clocks, then
1098 monotonic clocks, to the old realtime clock. Use make_timeval
1099 to round more-correctly when falling back to setitimer.
1100 (Fprofiler_cpu_start): Use it.
1101 (Fprofiler_cpu_stop): Prefer timer_settime if available.
1102 Don't assume that passing NULL as the 2nd argument of setitimer

1105 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
1106 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
1107 non-fatal signal handlers. Ignore SIGPROF on startup.
1108 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
1109 in profiler.c, since sysdep.c now uses it.
1111 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.
1112 Suggested by Eli Zaretskii in

1166 * charset.c, charset.h (maybe_unify_char): Now static.
1167 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
1168 Since this stuff is now private to charset.c, there's no need for
1169 a public macro and no need to inline by hand.

1202 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>

1241 (sigaction): Rewrite to call sys_signal instead of duplicating its
1243 (sys_kill): Improve commentary.
1245 * w32.c (term_ntproc): Accept (and ignore) one argument, for
1246 consistency with a signature of a signal handler. All callers
1248 (init_ntproc): Accept an argument DUMPING. If dumping, don't
1249 install term_ntproc as a signal handler for SIGABRT, as that
1250 should be done by the dumped Emacs.
1252 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
1254 * w32select.c (term_w32select): Protect against repeated
1255 invocation by setting clipboard_owner to NULL after calling

1321 (interruptible_wait_for_termination):
1322 Move these decls from lisp.h to syswait.h, since they use pid_t.

1373 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
1374 fatal_error_backtrace.
1376 * w32proc.c (sys_kill): Undo last change: don't do anything when

1416 (init_xpm_functions, init_png_functions, init_jpeg_functions)
1417 (init_tiff_functions, init_gif_functions, init_svg_functions):
1418 Arglist and w32_delayed_load calling convention changed.
1419 (gs_type): Remove init_gs_functions; there is no such function.
1420 (valid_image_p, make_image): Fix caller to lookup_image_type.
1422 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
1424 Simplify and avoid signal-handling races (Bug#12471).
1426 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
1427 Avoid recursive loop if there's a fatal error in the function itself.
1428 * atimer.c (pending_atimers):
1429 * blockinput.h: Don't include "atimer.h"; no longer needed.
1430 (interrupt_input_pending): Remove. All uses removed.
1431 pending_signals now counts both atimers and ordinary interrupts.
1432 This is less racy than having three separate pending-signal flags.
1433 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
1435 Rename from their upper-case counterparts BLOCK_INPUT,
1436 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
1437 INPUT_BLOCKED_P, and turn into functions. All uses changed.
1438 This makes it easier to access volatile variables more accurately.
1439 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
1440 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
1441 that's more reliable if the code is buggy and sets
1442 interrupt_input_blocked to a negative value. All uses changed.
1443 * atimer.c (deliver_alarm_signal):
1444 Remove. No need to deliver this to the parent; any thread can
1445 handle this signal now. All uses replaced by underlying handler.
1446 * atimer.c (turn_on_atimers):
1447 * dispnew.c (handle_window_change_signal):
1448 * emacs.c (handle_danger_signal):
1449 * keyboard.c (kbd_buffer_get_event):
1450 Don't reestablish signal handler; not needed with sigaction.
1451 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
1453 Rework to avoid unnecessary accesses to volatile variables.
1454 (UNBLOCK_INPUT_TO): Now a function.
1455 (totally_unblock_input, unblock_input): New decls.
1456 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
1457 (init_data): Remove. Necessary stuff now done in init_signal.
1458 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
1459 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
1460 (fatal_error_code): Remove; no longer needed.
1461 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
1462 it doesn't always backtrace. All uses changed. No need to reset
1463 signal to default, since sigaction and/or die does that for us now.
1464 Use emacs_raise (FOO), not kill (getpid (), FOO).
1465 (main): Check more-accurately whether we're dumping.
1466 Move fatal-error setup to sysdep.c
1467 * floatfns.c: Do not include "syssignal.h"; no longer needed.
1468 * gtkutil.c (xg_get_file_name, xg_get_font):
1469 Remove no-longer-needed signal-mask manipulation.
1470 * keyboard.c, process.c (POLL_FOR_INPUT):
1471 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
1472 * keyboard.c (read_avail_input): Remove.
1473 All uses replaced by gobble_input.
1474 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
1475 (kbd_buffer_store_event_hold, gobble_input):
1476 (record_asynch_buffer_change) [USABLE_SIGIO]:
1477 (store_user_signal_events):
1478 No need to mess with signal mask.
1479 (gobble_input): If blocking input and there are terminals, simply
1480 set pending_signals to 1 and return. All hooks changed to not
1481 worry about whether input is blocked.
1482 (process_pending_signals): Clear pending_signals before processing
1483 them, in case a signal comes in while we're processing.
1484 By convention callers now test pending_signals before calling us.
1485 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
1486 New functions, to support changes to blockinput.h.
1487 (handle_input_available_signal): Now extern.
1488 (reinvoke_input_signal): Remove. All uses replaced by
1490 (quit_count): Now volatile, since a signal handler uses it.
1491 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
1492 All callers changed. Block SIGINT only if not already blocked.
1493 Clear sigmask reliably, even if Fsignal returns, which it can.
1494 Omit unnecessary accesses to volatile var.
1495 (quit_throw_to_read_char): No need to restore sigmask.
1496 * keyboard.c (gobble_input, handle_user_signal):
1497 * process.c (wait_reading_process_output):
1498 Call signal-handling code rather than killing ourselves.
1499 * lisp.h: Include <float.h>, for...
1500 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
1501 (pending_signals): Now volatile.
1502 (syms_of_data): Now const if IEEE floating point.
1503 (handle_input_available_signal) [USABLE_SIGIO]:
1504 (terminate_due_to_signal, record_child_status_change): New decls.
1505 * process.c (create_process): Avoid disaster if memory is exhausted
1506 while we're processing a vfork, by tightening the critical section
1508 (send_process_frame, process_sent_to, handle_pipe_signal)
1509 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
1511 (send_process): No need for setjmp/longjmp any more, since the
1512 SIGPIPE stuff is now gone. Instead, report an error if errno
1514 (record_child_status_change): Now extern. PID and W are now args.
1515 Return void, not bool. All callers changed.
1516 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
1517 Remove. All uses removed. This bug should be fixed now in a
1519 (wait_for_termination_1): Use waitpid rather than sigsuspend,
1520 and record the child status change directly. This avoids the
1521 need to futz with the signal mask.
1522 (process_fatal_action): Move here from emacs.c.
1523 (emacs_sigaction_flags): New function, containing
1524 much of what used to be in emacs_sigaction_init.
1525 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
1526 caught by emacs, to make races less likely.
1527 (deliver_process_signal): Rename from handle_on_main_thread.
1529 (BACKTRACE_LIMIT_MAX): Now at top level.
1530 (thread_backtrace_buffer, threadback_backtrace_pointers):
1532 (deliver_thread_signal, deliver_fatal_thread_signal):
1533 New functions, for more-accurate delivery of thread-specific signals.
1534 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
1535 (deliver_arith_signal): Handle in this thread, not
1536 in the main thread, since it's triggered by this thread.
1537 (maybe_fatal_sig): New function.
1538 (init_signals): New arg DUMPING so that we can be more accurate
1539 about whether we're dumping. Caller changed.
1540 Treat thread-specific signals differently from process-general signals.
1541 Block all signals while handling fatal error; that's safer.
1542 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
1544 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
1545 Ignore SIGPIPE unless batch.
1546 (emacs_backtrace): Output backtrace for the appropriate thread,
1547 which is not necessarily the main thread.
1548 * syssignal.h: Include <stdbool.h>.
1549 (emacs_raise): New macro.
1550 * xterm.c (x_connection_signal): Remove; no longer needed
1551 now that we use sigaction.
1552 (x_connection_closed): No need to mess with sigmask now.
1553 (x_initialize): No need to reset SIGPIPE handler here, since
1554 init_signals does this for us now.
1556 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
1558 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
1559 background rect may be larger (Bug#12245).
1561 2012-09-23 Chong Yidong <cyd@gnu.org>
1563 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
1565 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
1567 * .gdbinit: Just stop at fatal_error_backtrace.
1568 See Stefan Monnier's request in
1569 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
1570 Remove no-longer-used query of system type.
1572 2012-09-22 Chong Yidong <cyd@gnu.org>
1574 * search.c (Freplace_match): Doc fix (Bug#12325).
1576 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
1578 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
1579 (Fline_end_position): Doc fix.
1581 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
1583 2012-09-22 Chong Yidong <cyd@gnu.org>
1585 * dispextern.h (struct image_type): Add new slot, storing a type
1586 initialization function.
1588 * image.c (define_image_type): Call the image initializer function
1589 if it is defined. Arguments and return value changed.
1590 (valid_image_p, make_image): Callers changed.
1591 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
1592 (gif_type, imagemagick_type, svg_type, gs_type):
1593 Add initialization functions.
1594 (Finit_image_library): Call lookup_image_type.
1595 (CHECK_LIB_AVAILABLE): Macro deleted.
1596 (lookup_image_type): Call define_image_type here, rather than via
1597 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
1598 (syms_of_image): Move define_image_type calls for xbm_type and
1599 pbm_type to lookup_image_type.
1601 2012-09-22 Eli Zaretskii <eliz@gnu.org>
1603 * keyboard.c (timer_check_2): Move calculation of 'timers' and
1604 'idle_timers' from here ...
1605 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
1606 lists, to avoid infloops when the timer does something stupid,
1607 like reinvoke itself with the same or smaller time-out.
1610 2012-09-22 Martin Rudalics <rudalics@gmx.at>
1612 * window.c (Fsplit_window_internal): Handle only Qt value of
1613 Vwindow_combination_limit separately.
1614 (Qtemp_buffer_resize): New symbol.
1615 (Vwindow_combination_limit): New default value.
1618 2012-09-22 Eli Zaretskii <eliz@gnu.org>
1620 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
1621 the new overlay string. (Bug#10159)
1623 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
1625 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
1626 or that fprintf is async-signal-safe. POSIX doesn't require
1629 2012-09-22 Chong Yidong <cyd@gnu.org>
1631 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
1634 2012-09-22 Kenichi Handa <handa@gnu.org>
1636 * composite.c (composition_reseat_it): Handle the case that a
1637 grapheme cluster is not covered by a single font (Bug#12352).
1639 2012-09-21 Chong Yidong <cyd@gnu.org>
1641 * image.c (define_image_type): Avoid adding duplicate types to
1642 image_types (Bug#12463). Suggested by Jörg Walter.
1644 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1646 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
1647 (print_load_command_name): Add case LC_DATA_IN_CODE.
1648 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
1650 2012-09-21 Glenn Morris <rgm@gnu.org>
1652 * eval.c (Frun_hook_with_args_until_success)
1653 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
1655 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
1657 * fileio.c (Ffile_selinux_context): Only call freecon when
1658 lgetfilecon succeeded.
1659 (Fset_file_selinux_context): Likewise. (Bug#12444)
1661 2012-09-21 Eli Zaretskii <eliz@gnu.org>
1663 * xdisp.c (try_window_reusing_current_matrix): Under bidi
1664 reordering, locate the cursor by calling set_cursor_from_row; if
1665 that fails, clear the desired glyph matrix before returning a
1666 failure indication to the caller. Fixes leaving garbled display
1667 when fast scrolling with a down-key. (Bug#12403)
1668 (compute_stop_pos_backwards): Fix a typo that caused crashes while
1669 scrolling through multibyte text.
1671 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
1673 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
1674 calling mark_vectorlike since that's the one that marks the window.
1675 (mark_discard_killed_buffers): Mark the final cdr.
1676 * window.h (struct window): Move prev/next_buffers to the
1677 non-standard fields.
1678 * window.c (make_window): Initialize prev/next_buffers manually.
1680 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
1682 Omit unused arg EXPECTED from socket hooks.
1683 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
1684 * nsterm.m (ns_term_init):
1685 * termhooks.h (struct terminal.read_socket_hook):
1686 * w32inevt.c (w32_console_read_socket):
1687 * w32term.c (w32_read_socket):
1688 * xterm.c (XTread_socket):
1689 Omit unused arg EXPECTED. All callers changed.
1690 (store_user_signal_events): Return void, not int, since callers no
1691 longer care about the return value. All uses changed.
1693 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
1695 * w32gui.h (XParseGeometry): Do not declare.
1697 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
1699 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
1700 Ignore 'expected'. See Eli Zaretskii in
1701 <http://bugs.gnu.org/12471#8> (last line).
1703 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
1704 (XParseGeometry): Now static. Substitute extremal values for
1705 values that are out of range.
1707 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
1709 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
1711 * nsfns.m (XParseGeometry): Remove.
1712 (Fx_create_frame): Call x_set_offset to correctly interpret
1713 top_pos in geometry.
1715 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
1716 (Fx_parse_geometry): If there is a space in string, call
1717 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
1719 2012-09-17 Eli Zaretskii <eliz@gnu.org>
1721 * search.c (scan_buffer): Use character positions in calls to
1722 region_cache_forward and region_cache_backward, not byte
1723 positions. (Bug#12196)
1725 * w32term.c (w32_read_socket): Set pending_signals to 1, like
1726 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
1728 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
1729 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
1730 emacs_blocked_malloc, now deleted.
1732 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
1734 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
1735 The workaround was for improving performance on Solaris 2.4, but
1736 is getting in the way now. Emacs will still work if someone is
1737 still running Solaris 2.4 in a museum somewhere; Sun dropped
1738 support for Solaris 2.4 in 2003.
1739 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
1740 * process.c (create_process) [HAVE_WORKING_VFORK]:
1741 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
1742 since Emacs no longer uses vfork on that platform.
1744 2012-09-17 Glenn Morris <rgm@gnu.org>
1746 * emacs.c: Use COPYRIGHT.
1748 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
1750 Remove configure's --without-sync-input option (Bug#12450).
1751 When auditing signal-handling in preparation for cleaning it up,
1752 I found that SYNC_INPUT has race conditions and would be a real
1753 pain to fix. Since it's an undocumented and deprecated
1754 configure-time option, now seems like a good time to remove it.
1755 Also see <http://bugs.gnu.org/11080#16>.
1756 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
1757 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
1758 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
1759 (malloc_hysteresis):
1760 (check_depth) [XMALLOC_OVERRUN_CHECK]:
1761 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
1762 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
1763 (dont_register_blocks, bytes_used_when_reconsidered)
1764 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
1765 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
1766 [!SYSTEM_MALLOC && !SYNC_INPUT]:
1767 Remove. All uses removed.
1768 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
1769 implementation, one that depends on whether the new macro
1770 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
1772 * atimer.c (run_timers, handle_alarm_signal):
1773 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
1774 (handle_async_input, process_pending_signals)
1775 (handle_input_available_signal, init_keyboard):
1776 * nsterm.m (ns_read_socket):
1777 * process.c (wait_reading_process_output):
1778 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
1779 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
1781 * xterm.c (XTread_socket):
1783 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
1784 * eval.c (handling_signal): Remove. All uses removed.
1785 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
1786 All uses replaced with the SYNC_INPUT version.
1787 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
1789 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
1792 * font.c (Ffont_shape_gstring): Remove unused local.
1794 2012-09-16 Glenn Morris <rgm@gnu.org>
1796 * Makefile.in (clean): No longer run nextstep's clean.
1798 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
1800 (ns-app): Move here from ns.mk, and simplify.
1801 (clean): Simplify nextstep entry.
1802 * ns.mk: Remove file.
1804 2012-09-17 Kenichi Handa <handa@gnu.org>
1806 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
1807 not covert the last few charactes.
1809 2012-09-16 Kenichi Handa <handa@gnu.org>
1811 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
1812 here, but just check the validity of glyphs in the glyph-string.
1814 2012-09-16 Martin Rudalics <rudalics@gmx.at>
1816 * window.c (Fwindow_parameter, Fset_window_parameter):
1817 Accept any window as argument (Bug#12452).
1819 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
1821 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
1822 to ns_term_init to avoid memory leak.
1824 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
1825 explicit retain/release.
1826 (ns_term_init): Only allow one display. Initialize outerpool and
1829 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
1831 Port _setjmp fix to POSIXish hosts as well as Microsoft.
1832 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
1833 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
1834 the Microsoft problem in a different way, by altering ../nt/config.nt.
1836 2012-09-15 Eli Zaretskii <eliz@gnu.org>
1851 * w16select.c: Remove inclusion of setjmp.h, as it is now included
1852 by lisp.h. This completes removal of setjmp.h inclusion
1853 erroneously announced in the previous commit. (Bug#12446)
1855 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
1858 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
1859 not defined as a macro. The latter happens on MS-Windows.
1862 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
1864 Port better to POSIX hosts lacking _setjmp (Bug#12446).
1865 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
1866 Some instances of '#include <setjmp.h>' removed, if the
1867 only reason for the instance was because "lisp.h" was included.
1868 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
1869 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
1870 and _longjmp with the new symbols. Emacs already uses _setjmp if
1871 available, so this change affects only POSIXish hosts that have
1872 sigsetjmp but not _setjmp, such as some versions of Solaris and
1873 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
1874 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
1875 (png_load_body) [HAVE_PNG]:
1876 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
1877 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
1878 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
1879 since PNG requires jmp_buf. This is the only exception to the
1880 general rule that we now use sys_setjmp and sys_longjmp.
1881 This exception is OK since this code does not change the signal
1882 mask or longjmp out of a signal handler.
1884 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
1886 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
1887 Include "syssignal.h", for 'main_thread'.
1889 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
1891 Avoid out-of-range marker position (Bug#12426).
1892 * insdel.c (replace_range, replace_range_2):
1893 Adjust markers before overlays, as suggested by comments.
1894 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
1895 Remove redundant check before calling offset_intervals.
1897 2012-09-14 Martin Rudalics <rudalics@gmx.at>
1899 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
1900 current buffer (Bug#12387).
1902 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
1904 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
1906 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
1908 Use a more backwards-compatible timer format (Bug#12430).
1909 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
1910 vector element, not from the 4th, since PSECS is now at the end.
1911 (Fcurrent_idle_time): Doc fix.
1913 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
1915 Function to mark objects and remove killed buffers at once.
1916 * alloc.c (discard_killed_buffers): Rename to ...
1917 (mark_discard_killed buffers) ... new name. Add marking
1918 of remaining objects. Fix comment. Adjust users.
1919 (mark_object): Do not touch frame buffer lists here.
1920 * frame.c (delete_frame): Reset frame buffer lists here.
1922 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
1924 Better workaround for GNOME bug when --enable-gcc-warnings.
1925 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
1926 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
1927 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
1929 Simplify SIGIO usage (Bug#12408).
1930 The code that dealt with SIGIO was crufty and confusing, e.g., it
1931 played tricks like "#undef SIGIO" but these tricks were not used
1932 consistently. Simplify mostly by not #undeffing standard symbols,
1933 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
1934 or not as we please) rather than "defined SIGIO" (standard symbol
1935 that we probably shouldn't #undef).
1936 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
1937 Modules that need it can include it.
1938 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
1939 * dispextern.h (ignore_sigio): New decl.
1940 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
1941 unconditionally, since it's now a no-op if !USABLE_SIGIO.
1942 * emacs.c (shut_down_emacs):
1943 * keyboard.c (kbd_buffer_store_event_hold):
1944 Use ignore_sigio rather than invoking 'signal' directly.
1945 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
1947 (FIONREAD, SIGIO): Do not #undef.
1948 (tty_read_avail_input): Use #error rather than a syntax error.
1949 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
1950 for I_PIPE, used by SETUP_SLAVE_PTY.
1951 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
1952 * sysdep.c (croak): Remove; no longer needed. This bit of
1953 temporary code, with Fred N. Fish's comment that it's temporary,
1954 has been in Emacs since at least 1992!
1955 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
1956 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
1957 * syssignal.h (croak): Remove decl.
1958 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
1959 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
1960 now that we're termios-only.
1961 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
1962 * term.c (dissociate_if_controlling_tty): Use #error rather than
1965 Work around GCC and GNOME bugs when --enable-gcc-warnings.
1966 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
1967 to work around GNOME bug 683906.
1968 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
1969 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
1970 This works around GCC bug 54561.
1972 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
1974 More fixes for 'volatile' and setjmp/longjmp.
1975 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
1976 * image.c (struct png_load_context) [HAVE_PNG]: New type.
1977 (png_load_body) [HAVE_PNG]:
1978 (jpeg_load_body) [HAVE_JPEG]:
1979 New function, with most of the old parent function's body.
1980 (png_load) [HAVE_PNG]:
1981 (jpeg_load) [HAVE_JPEG]:
1982 Invoke the new function, to avoid longjmp munging our locals.
1983 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
1984 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
1985 longjmp is passed 2, as the C standard doesn't guarantee this.
1986 Instead, store the failure code into mgr->failure_code.
1988 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
1990 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
1991 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
1992 (syms_of_keyboard): Remove support for unread-command-char.
1994 2012-09-12 Eli Zaretskii <eliz@gnu.org>
1996 * w32proc.c (sys_kill): If PID is our process ID and the signal is
1997 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
1998 violation. (Bug#12426)
2000 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
2002 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
2004 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
2006 * eval.c: Add `inhibit-debugger'.
2007 (Qinhibit_debugger): New symbol.
2008 (call_debugger): Bind it instead of Qdebug_on_error.
2009 (maybe_call_debugger): Test Vinhibit_debugger.
2010 (syms_of_eval): Define inhibit-debugger.
2011 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
2012 (syms_of_xdisp): Remove inhibit-debug-on-message.
2014 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
2016 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
2017 If a nonvolatile local variable is written before a _longjmp to
2018 the frame containing the variable, and is read after the _longjmp,
2019 the value read is indeterminate. Some local variables of type
2020 'struct handler' and 'struct catchtag' are used in this way, so
2021 mark each of their slots as volatile if the slot can be set before
2022 _longjmp and read afterwards.
2023 * lisp.h (struct handler): var and chosen_clause are now volatile.
2024 (struct catchtag): val, next, and pdlcount are now volatile.
2026 * bidi.c (bidi_push_it, bidi_pop_it):
2027 * fns.c (copy_hash_table):
2028 * image.c (define_image_type):
2029 * keyboard.c (kbd_buffer_store_event_hold):
2030 * process.c (Fprocess_send_eof):
2031 * xfaces.c (x_create_gc) [HAVE_NS]:
2032 * xgselect.c (xg_select):
2033 Prefer assignment to memcpy when either will do.
2035 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
2036 Use pointer-to-a-pointer to simplify and avoid a NILP check each
2037 time an item is removed. No need to mark this function 'inline';
2038 the compiler knows better than we do.
2040 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
2042 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
2043 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
2044 to change_frame_size (Bug#12388).
2045 (windowDidResize:): Pass YES to updateFrameSize.
2047 * nsterm.h: Add delay parameter to updateFrameSize.
2049 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
2051 Discard killed buffers from deleted window and frame objects.
2052 This reduces an amount of references to killed buffers and
2053 helps GC to reclaim them faster.
2054 * alloc.c (discard_killed_buffers): New function.
2055 (mark_object): Use it for deleted windows and frames.
2056 (mark_object): If symbol's value is set up for a killed buffer
2057 or deleted frame, restore its global binding.
2058 * data.c (swap_in_global_binding): Add GC notice.
2059 (swap_in_symval_forwarding): Use convenient set_blv_where.
2060 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
2061 * window.h: ... to here.
2063 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
2065 Convenient macro to check whether the buffer is live.
2066 * buffer.h (BUFFER_LIVE_P): New macro.
2067 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
2068 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
2070 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2072 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
2073 composition cases (Bug#12364).
2075 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
2076 overhang of succeeding glyphs overlapping box cursor.
2078 * w32term.c (x_draw_glyph_string): Likewise.
2080 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
2082 Simplify, document, and port floating-point (Bug#12381).
2083 The porting part of this patch fixes bugs on non-IEEE platforms
2084 with frexp, ldexp, logb.
2085 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
2087 * floatfns.c: Simplify discussion of functions that Emacs doesn't
2088 support, by removing commented-out code and briefly listing the
2089 C89 functions excluded. The commented-out stuff was confusing
2090 maintenance, e.g., we thought we needed cbrt but it was commented out.
2091 (logb): Remove decl; no longer needed.
2092 (isfinite): New macro, if not already supplied.
2093 (isnan): Don't replace any existing macro.
2094 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
2095 are present on all C89 platforms.
2096 (Ffrexp): Do not special-case zero, as frexp does the right thing
2098 (Flogb): Do not use logb, as it doesn't have the desired meaning
2099 on hosts that use non-base-2 floating point. Instead, stick with
2100 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
2101 frexp, to avoid getting an unspecified result.
2103 * xdisp.c (Qinhibit_debug_on_message): Now static.
2105 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
2107 * nsterm.m (ns_update_begin): Set clip path to whole view by using
2108 NSBezierPath (Bug#12131).
2110 2012-09-10 Chong Yidong <cyd@gnu.org>
2112 * fns.c (Fdelq, Fdelete): Doc fix.
2114 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
2116 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
2117 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
2119 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
2121 * lisp.h (make_lisp_ptr): New macro to replace XSET.
2122 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
2125 2012-09-09 Eli Zaretskii <eliz@gnu.org>
2127 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
2128 left fringe if the window has a left margin. This avoids leaving
2129 traces of the cursor because its leftmost pixel is not drawn over.
2131 * dispnew.c (update_window_line): When the left margin area of a
2132 screen line is updated, set the redraw_fringe_bitmaps_p flag of
2133 that screen line. (Bug#12277)
2135 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
2137 Assume C89 or later for math functions (Bug#12381).
2138 This simplifies the code, and makes it a bit smaller and faster,
2139 and (most important) makes it easier to clean up signal handling
2140 since we can stop worring about floating-point exceptions in
2141 library code. That was a problem before C89, but the problem
2142 went away many years ago on all practical Emacs targets.
2143 * data.c, image.c, lread.c, print.c:
2144 Don't include <math.h>; no longer needed.
2145 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
2146 might be autoconfigured, as that never happens.
2148 * doprnt.c (DBL_MAX_10_EXP):
2149 * print.c (DBL_DIG):
2150 Remove. C89 or later always defines these.
2151 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
2152 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
2153 (arith_error, domain_error, domain_error2):
2154 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
2155 no longer needed -- we simply return what C returns. All uses removed.
2156 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
2158 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
2159 Remove. All uses expanded, as these macros are no longer used
2160 more than once and are now more trouble than they're worth.
2161 (Ftan): Use tan, not sin / cos.
2162 (Flogb): Assume C89 frexp.
2163 (fmod_float): Assume C89 fmod.
2164 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
2165 (init_floatfns): Remove. All uses removed.
2167 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
2169 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
2170 compositeToPoint for OSX < 10.6 (Bug#12390).
2172 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
2174 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
2175 This produces more-accurate results.
2177 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
2179 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
2180 changes (Bug#12088).
2182 2012-09-08 Chong Yidong <cyd@gnu.org>
2184 * syntax.c (Fstring_to_syntax): Doc fix.
2186 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
2188 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
2189 in the internal border.
2190 (x_set_window_size): Remove static variables and their usage.
2191 (ns_redraw_scroll_bars): Fix NSTRACE arg.
2192 (ns_after_update_window_line, ns_draw_fringe_bitmap):
2193 Remove fringe/internal border adjustment (Bug#11052).
2194 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
2195 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
2196 (ns_fix_rect_ibw): Remove.
2197 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
2198 (ns_dumpglyphs_box_or_relief): Ditto.
2199 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
2201 (ns_dumpglyphs_image): Ditto.
2202 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
2204 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
2205 their usage. Add fringe_extended_p and its use as in other terms.
2206 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
2207 scroll bar was removed.
2208 (updateFrameSize): New function.
2209 (windowDidResize): Move code to updateFrameSize and call it.
2211 * nsterm.h (EmacsView): Add updateFrameSize.
2213 2012-09-07 Chong Yidong <cyd@gnu.org>
2215 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
2217 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
2219 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
2221 More signal-handler cleanup (Bug#12327).
2222 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
2223 Problem introduced when merging patches. Noted by Eli Zaretskii in
2224 <http://bugs.gnu.org/12327#67>.
2225 * floatfns.c: Comment fix.
2226 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
2227 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
2228 and anyway the declaration is harmless even if SIGDANGER is not defined.
2229 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
2230 defined BROKEN_FIONREAD). systty.h formerly did this, but other
2231 source files not surprisingly expected syssignal.h to define, or
2232 not define, SIGIO, and it's cleaner to do it that way, for consistency.
2233 Include <sys/ioctl.h>, for FIONREAD.
2234 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
2235 This eliminates a problem whereby other files mysteriously had
2236 to include "syssignal.h" before including "systty.h" if they
2237 wanted to use "#ifdef SIGIO".
2239 2012-09-07 Eli Zaretskii <eliz@gnu.org>
2241 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
2243 * w32.c (sigemptyset): Empty the set.
2244 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
2246 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
2248 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
2250 * alloc.c (mark_buffer): Revert unsafe marking optimization.
2251 (mark_object): Likewise for frame objects.
2253 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
2255 * syssignal.h (handle_on_main_thread): Always declare,
2256 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
2257 This ports to platforms without HAVE_PTHREAD.
2259 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
2261 Signal-handler cleanup (Bug#12327).
2262 Emacs's signal handlers were written in the old 4.2BSD style with
2263 sigblock and sigmask and so forth, and this led to some
2264 inefficiencies and confusion. Rewrite these to use
2265 pthread_sigmask etc. without copying signal sets around. Also,
2266 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
2267 'signal', and instead use functions that do not attempt to take
2268 over the system name space. This patch causes Emacs's text
2269 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
2270 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
2271 Do not include <signal.h> or "syssignal.h", as these
2272 modules do not use signals.
2273 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
2274 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
2275 Do not include <signal.h>, as "syssignal.h" does that for us now.
2276 * atimer.c (sigmask_atimers): New function.
2277 (block_atimers, unblock_atimers): New functions,
2278 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
2280 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
2281 no longer needed here.
2282 * emacs.c (main): Inspect existing signal handler with sigaction,
2283 so that there's no need to block and unblock SIGHUP.
2284 * sysdep.c (struct save_signal): New member 'action', replacing
2285 old member 'handler'.
2286 (save_signal_handlers, restore_signal_handlers):
2287 Use sigaction instead of 'signal' to save and restore.
2288 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
2289 New function. All users of 'signal' modified to use set_sighandler
2290 if they're writeonly, and to use sys_signal if they're read+write.
2291 (emacs_sigaction_init, forwarded_signal): New functions.
2292 (sys_signal): Remove. All uses replaced by calls to sigaction
2293 and emacs_sigaction_init, or by direct calls to 'signal'.
2294 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
2295 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
2296 all uses replaced by pthread_sigmask etc. calls.
2297 * syssignal.h: Include <signal.h>.
2298 (emacs_sigaction_init, forwarded_signal): New decls.
2299 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
2300 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
2301 (sigmask, sys_sigmask): Remove; no longer needed.
2302 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
2303 (sigblock, sigunblock, sigfree):
2304 (sigsetmask) [!defined sigsetmask]:
2305 Remove. All uses replaced by pthread_sigmask.
2306 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
2307 no longer need to be replaced, and its typical old uses
2308 are now done via emacs_sigaction_init and sigaction.
2309 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
2310 (sys_sigdel): Remove; unused.
2311 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
2313 2012-09-06 Eli Zaretskii <eliz@gnu.org>
2315 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
2316 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
2318 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
2320 Explicitly mark buffer_defaults and buffer_local_symbols.
2321 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
2322 mark_local_symbols here.
2323 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
2324 since special buffers aren't marked here any more.
2325 (allocate_buffer): Chain new buffer with all_buffers here...
2326 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
2328 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
2329 (syms_of_buffer): Remove staticpro of the above.
2330 (init_buffer_once): Set names for buffer_defaults and
2331 buffer_local_symbols.
2333 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
2335 Use bool for booleans in font-related modules.
2336 * font.c (font_intern_prop, font_style_to_value)
2337 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
2338 (generate_otf_features, font_check_otf_features, font_check_otf)
2339 (font_match_p, font_list_entities, font_at):
2340 * fontset.c (fontset_id_valid_p, reorder_font_vector
2341 (fontset_find_font, Fset_fontset_font)
2342 (face_suitable_for_char_p) [0]:
2343 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
2344 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
2345 (m17n_flt_initialized, ftfont_shape_by_flt):
2346 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
2347 * nsfont.m (nsfont_draw):
2348 * w32font.c (w32font_draw):
2349 * w32term.c (x_draw_glyphless_glyph_string_foreground):
2350 Use bool for booleans.
2351 * font.h: Adjust to above API changes.
2352 (struct font, struct font_driver, struct font_driver_list):
2353 Use bool for booleans.
2354 (struct font): Remove useless member encoding_type.
2356 * fontset.c, xftfont.c: Omit unnecessary static decls.
2358 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
2360 * alloc.c (mark_object): Revert window marking code
2361 since it's unsafe for the Fset_window_configuration.
2363 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
2365 Fix race conditions with signal handlers and errno (Bug#12327).
2366 Be more systematic about preserving errno whenever a signal
2367 handler returns, even if it's not in the main thread. Do this by
2368 renaming signal handlers to distinguish between signal delivery
2369 and signal handling. All uses changed.
2370 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
2371 * data.c (deliver_arith_signal): Rename from arith_error.
2372 * dispnew.c (deliver_window_change_signal): Rename from
2373 window_change_signal.
2374 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
2375 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
2376 * keyboard.c (deliver_input_available_signal): Rename from
2377 input_available_signal.
2378 (deliver_user_signal): Rename from handle_user_signal.
2379 (deliver_interrupt_signal): Rename from interrupt_signal.
2380 * process.c (deliver_pipe_signal): Rename from send_process_trap.
2381 (deliver_child_signal): Rename from sigchld_handler.
2382 * atimer.c (handle_alarm_signal):
2383 * data.c (handle_arith_signal):
2384 * dispnew.c (handle_window_change_signal):
2385 * emacs.c (handle_fatal_signal, handle_danger_signal):
2386 * keyboard.c (handle_input_available_signal):
2387 * keyboard.c (handle_user_signal, handle_interrupt_signal):
2388 * process.c (handle_pipe_signal, handle_child_signal):
2389 New functions, with the actual signal-handling code taken from the
2390 original respective signal handlers, sans the sporadic attempts to
2391 preserve errno, since that's now done by handle_on_main_thread.
2392 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
2393 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
2394 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
2396 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
2397 Move initialization of main_thread to sysdep.c's init_signals.
2398 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
2399 our usage, and simplifies the mainline code.
2400 (record_child_status_change): New static function, as a helper
2401 for handle_child_signal, and with most of the old child handler's
2403 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
2404 (handle_child_signal): Use the above.
2405 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
2406 Moved here from emacs.c.
2407 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
2408 code moved here from emacs.c's main function.
2409 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
2410 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
2411 This lets callers save and restore errno properly.
2413 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
2415 Remove redundant or unused things here and there.
2416 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
2417 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
2418 * editfns.c (Fcompare_buffer_substrings): Likewise.
2419 * frame.h (struct terminal, struct font_driver_list):
2420 Remove redundant declarations.
2421 * window.h (Qleft, Qright): Likewise.
2423 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
2425 Do not mark objects from deleted buffers, windows and frames.
2426 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
2427 (mark_object): Likewise for windows and frames.
2429 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
2431 * alloc.c (valid_lisp_object_p): Treat killed buffers,
2432 buffer_defaults and buffer_local_symbols as valid objects.
2433 Return special value to denote them.
2435 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
2437 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
2438 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
2439 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
2440 (file_name_absolute_p, Fsubstitute_in_file_name):
2441 (check_executable, check_writable, Ffile_accessible_directory_p)
2442 (Fset_file_selinux_context, Fdefault_file_modes)
2443 (Finsert_file_contents, choose_write_coding_system)
2444 (Fwrite_region, build_annotations, a_write, e_write)
2446 * filelock.c (boot_time_initialized, get_boot_time)
2447 (get_boot_time_1, lock_file_1, within_one_second):
2448 * floatfns.c (in_float):
2449 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
2450 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
2451 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
2452 * lisp.h (struct Lisp_Hash_Table.cmpfn):
2453 * window.c (compare_window_configurations):
2454 Use bool for booleans.
2455 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
2456 (Fdefault_file_modes): Now mode_t, not int, for modes.
2457 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
2458 (internal_delete_file): Now returns void, not a (boolean) int,
2459 since nobody was looking at the return value.
2460 * lisp.h, window.h: Adjust to above API changes.
2462 * xdisp.c (set_message): Simplify and reindent last change.
2464 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
2466 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
2468 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
2470 * eval.c (call_debugger): Make the function non-static so that we
2471 can call it from set_message.
2473 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
2474 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
2476 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
2478 Give more-useful info on a fatal error (Bug#12328).
2479 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
2480 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
2481 of doing the work ourselves.
2482 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
2483 do most of the work.
2484 (fatal_error_backtrace): New function, taken from the guts
2485 of the old fatal_error_signal, but with a new option to output
2487 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
2488 info about the signal than just its number.
2489 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
2490 * sysdep.c: Include <execinfo.h>
2491 (emacs_backtrace): New function, taken partly from the previous
2492 code of the 'die' function.
2493 (emacs_abort): Call fatal_error_backtrace rather than abort.
2495 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
2497 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
2498 eager (load-time) macro-expansion.
2499 * lisp.mk (lisp): Add macroexp.
2501 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
2503 Simplify redefinition of 'abort' (Bug#12316).
2504 Do not try to redefine the 'abort' function. Instead, redo
2505 the code so that it calls 'emacs_abort' rather than 'abort'.
2506 This removes the need for the NO_ABORT configure-time macro
2507 and makes it easier to change the abort code to do a backtrace.
2508 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
2509 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
2510 Remove; sysdep.c's emacs_abort now takes its place.
2511 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
2512 'abort' changed to use 'emacs_abort'.
2513 * msdos.c (dos_abort) [defined abort]: Remove; not used.
2514 (abort) [!defined abort]: Rename to ...
2515 (emacs_abort): ... new name.
2516 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
2517 the place of the old 'abort' in emacs.c.
2518 * w32.c, w32fns.c (abort): Do not #undef.
2519 * w32.c (emacs_abort): Rename from w32_abort.
2521 2012-09-04 Eli Zaretskii <eliz@gnu.org>
2523 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
2524 offsets[j].dv, since the y axis of the screen coordinates points
2525 down, while the y axis of the font definition coordinates points
2526 up. This fixes display of Arabic diacritics such as KASRA and
2527 KASRATAN. (Bug#11860)
2529 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
2531 Be more systematic about _setjmp vs setjmp.
2532 * alloc.c (test_setjmp, mark_stack):
2533 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
2534 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
2535 (png_load, my_error_exit, jpeg_load):
2536 * process.c (send_process_trap, send_process):
2537 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
2538 The underscored versions are up to 30x faster on some hosts.
2539 Formerly, the code used setjmp+longjmp sometimes and
2540 _setjmp+_longjmp at other times, with no particular reason to
2541 prefer setjmp+longjmp.
2543 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
2545 Fix minor problem found by static checking.
2546 * buffer.c (Fdelete_all_overlays): Return nil.
2548 2012-09-03 Martin Rudalics <rudalics@gmx.at>
2550 * buffer.c (Fdelete_all_overlays): New function.
2552 2012-09-03 Chong Yidong <cyd@gnu.org>
2554 * gtkutil.c: Add extern decl for Qxft.
2556 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
2558 * emacs.c, eval.c: Use bool for boolean.
2559 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
2560 (malloc_using_checking) [DOUG_LEA_MALLOC]:
2561 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
2562 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
2563 (main, decode_env_path, Fdaemon_initialized):
2564 * eval.c (call_debugger, Finteractive_p, interactive_p):
2565 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
2566 (maybe_call_debugger, Fbacktrace):
2567 * process.c (read_process_output, exec_sentinel):
2568 Use bool for booleans.
2569 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
2570 All callers changed.
2571 * eval.c (interactive_p): Omit always-true boolean argument
2572 EXCLUDE_SUBRS_P. All callers changed.
2573 * dispextern.h, lisp.h: Reflect above API changes.
2574 * firstfile.c (dummy): Use the address of 'main', whose signature
2575 won't change, instead of the address of 'initialize', whose
2576 signature just changed from int to bool.
2577 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
2578 * msdos.c (fatal_error_in_progress): ... from here.
2579 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
2581 (redisplay_internal, unwind_redisplay): Simply clear
2582 REDISPLAYING_P when unwinding, instead of saving its previous,
2583 always-false value and then restoring it.
2585 Clean up some extern decls.
2586 Mostly, this hoists extern decls out of .c files and into .h files.
2587 That way, we're more likely to catch errors if the interfaces change.
2588 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
2589 declare xg_mark_data.
2590 * dispextern.h (x_frame_parm_handlers):
2592 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
2593 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
2594 (Qultra_bold, Qoblique, Qitalic):
2595 Move extern decl here from .c file.
2596 * alloc.c (xg_mark_data) [USE_GTK]:
2598 * eval.c (Qlexical_binding):
2599 * fns.c (time) [!HAVE_UNISTD_H]:

2605 * process.c (QCfamily, QCfilter):
2606 * widget.c (free_frame_faces):
2607 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
2608 * xfont.c (x_clear_errors):
2609 * xterm.c (x_frame_parm_handlers):
2610 Remove now-redundant extern decls.
2611 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
2612 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
2614 * xfaces.c: Remove unnecessary static decls.
2615 * xterm.c (updating_frame): Remove decl of nonexistent object.
2617 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
2618 when building globals.h, as the objects that are not built on
2619 this host are not needed to compile C files on this host.
2621 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
2623 * gtkutil.h: Remove prototype for x_wm_set_size_hint.
2625 * frame.h: Add missing prototype for x_wm_set_size_hint.
2627 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>

2631 (Fdocumentation, Fdocumentation_property, Fsnarf_documentation)
2632 (Fsubstitute_command_keys):

2634 (save_excursion_save, save_excursion_restore)
2635 (disassemble_lisp_time, decode_time_components, emacs_nmemftime)
2636 (format_time_string, general_insert_function)
2637 (make_buffer_string, make_buffer_string_both)
2638 (Fsubst_char_in_region, Ftranslate_region_internal, Fformat):
2639 * insdel.c (check_markers, gap_left, adjust_markers_for_insert)

2656 2012-09-02 Chong Yidong <cyd@gnu.org>
2658 * keymap.c (push_key_description): Print M-TAB as C-M-i
2661 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
2663 * makefile.w32-in (CCL_H, W32FONT_H): New macros.
2664 (ATIMER_H, FONT_H, $(BLD)/alloc.$(O), $(BLD)/callproc.$(O))

2669 ($(BLD)/w32font.$(O), $(BLD)/w32uniscribe.$(O)): Update dependencies.
2671 2012-09-01 Eli Zaretskii <eliz@gnu.org>
2673 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
2674 more than one grapheme cluster passed to the shaper: compute the
2675 offset adjustment values separately for each cluster. (Bug#11860)
2677 * image.c: Restore mistakenly removed inclusion of w32.h. Without
2678 it, GCC doesn't see prototypes of w32_delayed_load, and complains
2679 about implicit conversions from integer to pointer.
2681 2012-09-01 Daniel Colascione <dancol@dancol.org>
2683 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
2684 system used too early.
2686 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
2688 Better seed support for (random).
2689 * emacs.c (main): Call init_random.
2690 * fns.c (Frandom): Set the seed from a string argument, if given.
2691 Remove long-obsolete Gentzel cruft.

2693 (init_random): New function.
2695 2012-09-01 Daniel Colascione <dancol@dancol.org>
2697 * xterm.h: Add header guards. Declare x_menubar_window_to_frame.
2698 Remove x_set_frame_alpha, x_bitmap_icon, x_make_frame_visible,
2699 x_make_frame_invisible, x_iconify_frame, x_free_frame_resources,
2700 x_wm_set_size_hint, x_query_colors, x_real_positions,
2701 x_set_menu_bar_lines, x_char_width, x_char_height, x_sync,
2702 x_set_tool_bar_lines, x_activate_menubar, and free_frame_menubar,
2703 all of which have been moved to common code.
2705 * xfaces.c: Include TERM_HEADER instead of listing all possible
2706 window-system headers.
2708 * w32xfns.c (x_sync): Correct definition of x_sync (a no-op here)
2711 * w32term.h (FRAME_X_WINDOW): Use FRAME_W32_WINDOW instead of
2712 directly accessing frame internals.
2714 * w32font.h: Include font.h. Define syms_of_w32font and
2717 * process.c: Include TERM_HEADER instead of listing all possible
2718 window-system headers.
2720 * nsterm.h: Remove declarations now in frame.h.
2721 Define FRAME_X_SCREEN, FRAME_X_VISUAL.
2723 * menu.c: Include TERM_HEADER instead of listing all possible
2724 window-system headers.
2726 * keyboard.h: Declare ignore_mouse_drag_p whenever we have a
2729 * keyboard.c: Include TERM_HEADER instead of listing all possible
2730 window-system headers.
2732 * image.c: Include TERM_HEADER instead of listing all possible
2733 window-system headers. Declare Vlibrary_cache when compiling for
2736 * gtkutil.h (xg_list_node_): Include xterm.h to pick up needed
2737 window system declarations.

2793 * gtkutil.c (x_wm_set_size_hint): Use 1 col for base_width so it
2794 does not become zero (Bug#12234).

2824 (timeout_handler:): Set timer_fired to YES.
2825 (runDialogAt:): Set timer_fired to NO.
2826 Handle click on close button as quit.
2828 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
2829 Add window_closed and button_values. Add void as return value for
2830 add(Button|String|Split). addButton takes int instead of Lisp_Object.
2831 Add process_dialog as new member.
2833 2012-08-28 Eli Zaretskii <eliz@gnu.org>
2835 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it
2836 is not one of the heaps we manage. (Bug#12242)
2838 2012-08-28 Glenn Morris <rgm@gnu.org>

2908 2012-08-27 Martin Rudalics <rudalics@gmx.at>
2910 * window.c (Fset_window_configuration): Revert first part of
2913 2012-08-27 Jan Djärv <jan.h.d@swipnet.se>
2915 * nsterm.h (NSPanel): New class variable dialog_return.

2918 Initialize dialog_return.
2919 (windowShouldClose:): Use stop instead of stopModalWithCode.
2920 (clicked:): Ditto, and also set dialog_return (Bug#12258).
2921 (timeout_handler:): Use stop instead of abortModal. Send a dummy

2970 * coding.c: Remove unnecessary static function decls.
2971 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
2972 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
2973 not a boolean 'int', since callers never look at the return value.
2974 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
2975 * coding.h (decoding_buffer_size, encoding_buffer_size)
2976 (emacs_mule_string_char): Remove unused extern decls.
2977 (struct iso_2022_spec, struct coding_system):

2985 Fix spare memory change (Bug#12286).
2986 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
2987 (valid_lisp_object_p): Likewise.
2989 2012-08-27 Martin Rudalics <rudalics@gmx.at>
2991 * window.c (Fset_window_configuration): Record any window's old
2992 buffer if it's replaced (see Bug#8789). If the new current
2993 buffer doesn't appear in the selected window, go to its old
2996 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
2998 Special MEM_TYPE_SPARE to denote reserved memory.
2999 * alloc.c (enum mem_type): New memory type.
3000 (refill_memory_reserve): Use new type for spare memory.
3001 This prevents live_cons_p and live_string_p from incorrect

3004 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
3007 * Makefile.in (.PHONY): versioclean -> versionclean.

3011 * window.c (Qwindow_valid_p, decode_valid_window):
3012 Now static, not extern.
3013 * data.c (Qinterval): Remove; unused.

3030 (map_sub_char_table):
3031 Use bool for boolean.
3032 * character.c (str_to_unibyte): Omit last boolean argument; it was
3033 always 0. All callers changed.
3034 * character.h, charset.h: Adjust to match previous changes.
3035 * character.h (char_printable_p): Remove decl of nonexistent function.
3036 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
3037 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
3038 are all boolean, so make them single-bit bitfields.
3040 * lisp.h (ASET): Remove attempt to detect side effects.
3041 It was meant to be temporary and it often doesn't work,
3042 because when IDX has side effects the behavior of IDX==IDX
3043 is undefined. See Stefan Monnier in
3044 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
3046 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
3048 * lisp.h (functionp): New function (extracted from Ffunctionp).
3049 (FUNCTIONP): Use it.
3050 * eval.c (Ffunctionp): Use it.
3052 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
3054 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
3055 as that's faster and simpler than static storage. Don't bother
3056 with the g_main_context_query overhead if g_main_context_pending
3057 says no events are pending.
3058 (gfds, gfds_size): Remove these static vars.
3059 (xgselect_initialize): Remove; no longer needed.
3060 All uses and decls removed.
3062 * emacs.c (fatal_error_signal_hook): Remove.
3063 All uses removed. This leftover from old code was always 0.
3065 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
3066 * casefiddle.c (casify_object, casify_region):
3067 * casetab.c (set_case_table):

3078 On assertion failure, print backtrace if available.
3079 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.

3090 Use bool for booleans, instead of int.
3091 * lisp.h, process.h: Adjust prototypes to match above changes.
3092 * callint.c (Fcall_interactively): Don't assume the mark's
3093 offset fits in 'int'.

3105 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
3106 Use bool for booleans, instead of int.
3107 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
3108 since the 1-or-0 return value is always ignored anyway.
3109 (mmap_initialized_p):
3110 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
3111 * buffer.h, lisp.h: Adjust prototypes to match above changes.
3113 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
3115 * bidi.c: Use bool for boolean.
3116 This is a bit more readable, and makes the text segment of bidi.o
3117 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
3118 Presumably it's faster too.

3152 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
3154 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
3155 Otherwise, the compiler complains about (A?B:C) where B is void
3156 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
3157 (fontset_add): Return void, for FONTSET_ADD.
3159 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>

3181 (make_pure_string, gc_in_progress, abort_on_gc):
3182 * lread.c (readchar, read1):
3183 * print.c (Fprin1_to_string):
3184 * xdisp.c (push_message):
3185 Use bool for booleans affected directly or indirectly by
3188 Make recently-introduced setters macros.
3189 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
3190 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
3191 (set_fontset_default, set_fontset_fallback): Rename from their
3192 upper-case counterparts, and make them functions rather than macros.
3193 This is more consistent with the other recently-introduced setters.
3194 These don't need to be inline, since they're local.
3196 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
3198 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in

3201 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
3203 * lisp.h (vcopy): Use memcpy rather than our own loop.
3204 This fixes a performance regression introduced by the recent
3205 addition of vcopy. This means 'vcopy' will need to be modified
3206 for a copying collector, but that's OK. Also, tighten the
3207 checking in the assertion.
3209 2012-08-21 Eli Zaretskii <eliz@gnu.org>
3211 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
3212 components for RTL text (Bug#11860). Adjust X-OFFSET of each
3213 non-base glyph for the width of the base character, according to
3214 what x_draw_composite_glyph_string_foreground expects.
3215 Generate WADJUST value according to composition_gstring_width's
3216 expectations, to produce correct width of the composed character.
3217 Reverse the sign of the DU offset produced by ScriptPlace.
3219 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
3221 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.

3242 buffer to the specified position.
3244 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>

3247 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
3248 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
3249 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
3252 2012-08-20 Glenn Morris <rgm@gnu.org>
3254 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
3255 Don't assume that `ln -f' works.
3257 2012-08-20 Eli Zaretskii <eliz@gnu.org>
3259 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
3260 and later about non-assignments with no effect. See discussion at
3261 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
3264 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
3266 Inline setter functions for Lisp_Objects slots of struct specbinding.
3267 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
3270 2012-08-20 Martin Rudalics <rudalics@gmx.at>
3272 * window.c (select_window): Always make selected window's buffer
3275 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>

3278 * category.h (CATEGORY_DOCSTRING): Use AREF.
3279 (SET_CATEGORY_DOCSTRING): Use ASET.
3280 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
3282 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
3284 Inline setter functions for hash table members.
3285 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
3286 (set_hash_hash, set_hash_index): Rename with _slot suffix.
3287 (set_hash_key_and_value, set_hash_index, set_hash_next)
3288 (set_hash_hash): New functions.
3289 * charset.c, fns.c: Adjust users.
3291 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
3293 Inline getter and setter functions for per-buffer values.

3297 * buffer.c, data.c: Adjust users.
3299 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
3301 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
3303 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
3305 Rely on <config.h> + <unistd.h> to declare 'environ',
3306 as gnulib does this if the system doesn't.
3307 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
3308 Remove declaration. MS-Windows declares it on stdlib.h which is
3309 included by conf_post.h.
3310 * emacs.c (environ) [DOUG_LEA_MALLOC]:
3311 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
3312 * vm-limit.c: Include <unistd.h>, for 'environ'.
3314 * unexaix.c, unexcoff.c: Include "mem-limits.h".
3315 (start_of_data): Remove decl; mem-limits.h provides it.
3317 * xdisp.c (handle_invisible_prop): Make it a bit faster
3318 and avoid a gcc -Wmaybe-uninitialized diagnostic.
3320 2012-08-19 Chong Yidong <cyd@gnu.org>
3322 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
3325 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>

3330 * data.c (set_internal): Don't use set_blv_found.
3331 (Fkill_local_variable): Likewise.
3333 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
3335 * nsfont.m (ns_ascii_average_width): Ensure the string
3336 ascii_printable is initialized with a null-terminated character
3337 array. Otherwise, it can contain undesired extra characters.
3339 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
3341 port new setting code to Sun C 5.8 2005/10/13
3342 * chartab.c, lisp.h (char_table_set, char_table_set_range):
3343 Return void, not Lisp_Object. Otherwise, the compiler
3344 complains about (A?B:C) where B is void and C is Lisp_Object
3345 when compiling CHAR_TABLE_SET, due to the recent change to
3346 the API of sub_char_table_set_contents.
3348 2012-08-18 Chong Yidong <cyd@gnu.org>
3350 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE

3521 directly-specified attributes.
3522 (merge_face_ref): Recognize :font.
3524 2012-08-17 Dmitry Antipov <dmantipov@yandex.ru>

3572 types, since we want the ASCII interpretation here, not the
3573 interpretation suitable for whatever happens to be the current locale.

4178 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
4179 * w32.c (init_environment): Change the default values of many
4180 environment variables in dflt_envvars[] to NULL, to avoid pushing
4181 them into environment when they were not already defined.
4182 Remove the code that deletes site-lisp subdirectories from the default
4183 value of EMACSLOADPATH, as it is no longer needed.
4184 (check_windows_init_file): Now external, not static.
4185 Use Vload_path as is, without adding anything, as this function is now
4186 called when Vload_path is already set up.
4188 * w32.h (check_windows_init_file): Add prototype.
4190 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

4192 compatibility with Posix platforms.
4193 (main): Move the call to check_windows_init_file to here from

4197 installation tree, as appropriate.
4199 * callproc.c (init_callproc_1): Call decode_env_path instead of
4200 doing its equivalent by hand.
4201 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
4202 the code that sets Vexec_path run on MS-Windows.

4218 Remove unnecessary casts involving pointers.
4219 These casts are no longer needed now that we assume C89 or later,

4233 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
4234 Remove unnecessary pointer casts.
4235 * alloc.c (record_xmalloc): New function.
4236 * lisp.h (record_xmalloc): New decl.
4237 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
4238 more like a function. This is because the pointer cast is not
4239 needed. All uses changed.
4240 * print.c (print_string, print_error_message): Avoid length recalc.
4242 Improve fix for macroexp crash with debugging (Bug#12118).
4243 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
4244 ARRAY_MARK_FLAG when checking subscripts, because ASET is
4245 not supposed to be invoked from the garbage collector.
4246 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
4247 (gc_aset): New function, which is like ASET but can be
4248 used in the garbage collector.

4264 headers (most versions of MinGW w32api don't).
4265 (get_security_info, create_symbolic_link)
4266 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):

4277 with addition of handling of symlinks and support for 'lstat'.
4278 If possible, get file's attributes and security information by
4279 handle, not by name. Produce S_IFLNK bit for symlinks, when
4280 called from 'lstat'.
4281 (stat, lstat): New functions, call 'stat_worker'.
4282 (symlink, readlink, careadlinkat): Rewritten to create and resolve
4283 symlinks when the underlying filesystem supports them.
4285 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
4287 Fix macroexp crash on Windows with debugging (Bug#12118).
4288 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
4289 checking subscripts; problem introduced with the recent
4290 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
4291 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
4292 since it's used in non-static inline functions now.
4294 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
4295 Don't assume buffer size fits in 'int'. Remove unused local.

4313 * character.c (CHARACTER_INLINE):
4314 * charset.c (CHARSET_INLINE):
4315 * composite.c (COMPOSITE_INLINE):
4316 * dispnew.c (DISPEXTERN_INLINE):
4317 * sysdep.c (SYSTIME_INLINE):
4318 Define to EXTERN_INLINE, so that the corresponding functions
4319 are compiled into code.
4320 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
4321 (INLINE_HEADER_END): New macros.
4322 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

4342 hard-coding the path separator.
4344 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
4346 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
4347 This how ASET and AREF are supposed to work, and makes
4348 it easier to think about future improvements. See
4349 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
4350 * charset.h (set_charset_attr): New function.

4604 does that unconditionally. Remove file, which is now empty.
4606 * s/freebsd.h, s/gnu-linux.h, s/sol2-6.h, s/unixware.h:
4609 2012-07-30 Paul Eggert <eggert@cs.ucla.edu>
4611 Export to GDB most of lisp.h's remaining object-like macros.

4727 * w32inevt.c: Include w32inevt.h.
4728 (w32_read_console_input): New inline function, calls either
4729 ReadConsoleInputA or ReadConsoleInputW, depending on the value of
4730 w32_console_unicode_input.
4731 (fill_queue): Call w32_read_console_input instead of ReadConsoleInput.
4732 (w32_kbd_patch_key, key_event): Use the codepage returned by
4733 GetConsoleCP, rather than the ANSI codepage returned by GetLocaleInfo.

4765 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
4766 enumeration constants, as PURE and HEAP are too general, and clash
4767 with other headers and sources, such as gmalloc.c and the
4768 MS-Windows system headers. All users changed.
4770 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
4772 Revert last save_excursion_save and save_excursion_restore changes.
4773 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

4783 2012-07-27 Paul Eggert <eggert@cs.ucla.edu>
4785 Improve GDB symbol export (Bug#12036).
4786 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
4787 arms of an 'if', not using conditional expressions; otherwise GDB
4788 complains about the types in the unevaluated arm when the argument
4789 is an integer literal.
4790 (xgetint): Simplify expression.
4791 * alloc.c (gdb_make_enums_visible): New constant. This ports to
4792 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
4793 Zaretskii in <http://bugs.gnu.org/12036#13>.
4794 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
4795 needed now that we have gdb_make_enums_visible.
4796 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
4797 (enum enum_USE_LSB_TAG):
4798 New enum types, packaging up enums that need to be exported to GDB.

4816 * xdisp.c (syms_of_xdisp): Likewise.
4817 * xfns.c (syms_of_xfns): Likewise.
4819 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
4821 Fast save_excursion_save and save_excursion_restore.
4822 * lisp.h (struct Lisp_Excursion): New data type.
4823 (PVEC_EXCURSION): New pseudovector type.
4824 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
4825 to deal with it. Adjust comments.

4836 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
4838 Fix export of symbols to GDB (Bug#12036).
4839 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
4840 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
4841 emacs.c, as this is a more-suitable home. Had this been done earlier
4842 the fix for 12036 would have avoided some of the problems noted in
4843 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
4844 would have been more obvious.
4845 * emacs.c: Do not include <verify.h>; no longer needed.
4846 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
4847 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
4848 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
4849 Remove; now done in lisp.h.
4850 * lisp.h (PUBLISH_TO_GDB): New macro.

4852 (DATA_SEG_BITS): Use it.
4853 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
4854 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
4855 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
4856 not be usable in #if. This simplifies things.
4858 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
4860 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
4862 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
4864 Simplify export of symbols to GDB (Bug#12036).
4865 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
4866 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
4867 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
4868 Adjust to changes in lisp.h and emacs.c, by using
4869 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
4870 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
4871 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
4872 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
4873 instead of gdb_valbits.
4874 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
4875 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
4876 instead of gdb_array_mark_flag.
4877 (xboolvector): Get size from $->size, not $->header.size.
4878 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
4879 (xreload, hook-run, hookpost-run): Remove.
4880 * emacs.c: Include <verify.h>.
4881 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
4882 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
4884 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
4885 (gdb_USE_LSB_TAG): New enum constants.
4886 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
4887 Also define these as enum constants, so they're visible to GDB.
4888 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
4889 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
4890 as constants, so they're visible to GDB.
4891 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
4892 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
4893 Now enum constants, not macros, so they're visible to GDB.
4894 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
4895 more convenient now. All uses changed.
4896 (VALMASK) [USE_LSB_TAG]: Also define in this case.
4897 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
4899 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>
4901 Explicitly free restriction data that are not needed anymore.
4902 * editfns.c (save_restriction_restore): Free restriction data.
4904 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
4906 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
4907 add argument, tune behavior, and adjust all callers.
4909 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
4911 Use typedef for EMACS_INT, EMACS_UINT.
4912 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
4913 than macros. This simplifies debugging in the usual case, since
4914 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
4915 and it allows expressions involving EMACS_INT casts.
4916 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
4918 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>
4920 * nsterm.m (ns_read_socket): Return early if there is a modal
4923 2012-07-25 Martin Rudalics <rudalics@gmx.at>
4925 * frame.c (Fredirect_frame_focus): In doc-string don't mention
4926 that FOCUS-FRAME can be omitted.
4928 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
4930 Adjust buffer text indirection counters at the end of Fkill_buffer.
4931 * buffer.c (Fkill_buffer): Adjust indirection counters when the

5779 Prefer snprintf to strncpy.
5780 * nsterm.m (ns_term_init):
5781 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
5782 * nsterm.m (ns_term_init):
5783 Avoid the need for strncpy, by using build_string or
5784 make_unibyte_string directly. Use dtoastr, not snprintf.
5785 * process.c (Fmake_network_process): Diagnose service names that
5786 are too long, rather than silently truncating them or creating

5836 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
5838 Avoid calls to strlen in path processing functions.
5839 * fileio.c (file_name_as_directory): Add comment. Change to add
5840 srclen argument and return the length of result. Adjust users
5842 (directory_file_name): Fix comment. Change to add srclen argument,
5843 swap 1st and 2nd arguments to obey the common convention.
5844 Adjust users accordingly.
5845 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
5847 2012-07-10 Glenn Morris <rgm@gnu.org>
5849 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
5850 Move PENDING_OUTPUT_COUNT definition to configure.
5852 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
5853 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
5854 * s/gnu.h (DATA_START): Move definitions to configure.
5856 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
5857 We include usg5-4-common.h, which defines them both.
5859 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
5860 O_RDONLY already includes it).
5862 Stop ns builds setting the EMACSLOADPATH environment variable.
5863 * nsterm.m (ns_load_path): Rename from ns_init_paths.
5864 Now it does not set EMACSLOADPATH, just returns the load-path string.
5865 * nsterm.h: Update accordingly.
5866 * lread.c [HAVE_NS]: Include nsterm.h.
5867 (init_lread) [HAVE_NS]: Use ns_load_path.

5870 2012-07-09 Glenn Morris <rgm@gnu.org>
5872 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
5873 since the included bsd-common.h does so.
5875 Stop ns builds setting the EMACSPATH environment variable.
5876 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
5877 (ns_init_paths): Do not set EMACSPATH.
5878 * nsterm.h (ns_exec_path): Add it.
5879 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
5882 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
5884 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
5886 * process.c (wait_reading_process_output): 'waitchannels' was unset
5887 when read_kbd || !NILP (wait_for_cell); fix this.
5889 Add GCC-style 'const' attribute to functions that can use it.
5890 * character.h (char_resolve_modifier_mask):
5891 * keyboard.h (make_ctrl_char):
5892 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
5893 (init_character_once, next_almost_prime, init_fns, init_image)
5894 (flush_pending_output, init_sound):

5899 Declare the dummy function with ATTRIBUTE_CONST.
5900 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
5901 Add decls with ATTRIBUTE_CONST.
5903 Minor improvements to make_formatted_string.
5904 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
5905 where int is good enough, as vsprintf returns an int.
5906 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
5908 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
5910 Use make_formatted_string to avoid double length calculation.
5911 * lisp.h (make_formatted_string): New prototype.
5912 * alloc.c (make_formatted_string): New function.
5913 * buffer.c (Fgenerate_new_buffer_name): Use it.

5933 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
5935 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
5937 Move marker debugging code under MARKER_DEBUG.
5938 * marker.c (MARKER_DEBUG): Move marker debugging code under
5939 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
5940 for bootstrap with --enable-checking (~3x slowdown reported
5941 by Juanma Barranquero <lekktu@gmail.com>).
5942 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
5944 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
5946 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
5947 See <http://bugs.gnu.org/11825#29>.
5949 2012-07-08 Eli Zaretskii <eliz@gnu.org>
5951 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
5952 has no font, use the frame's font. (Bug#11813)
5953 (display_line): Add commentary about displaying truncation glyphs
5955 (produce_special_glyphs): Move here from term.c.
5957 * term.c (produce_special_glyphs): Move to xdisp.c.
5959 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
5962 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
5964 * xdisp.c (display_line): Avoid warning about implicit declaration
5967 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
5969 * lisp.h: Remove empty conditional.
5971 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
5973 * lread.c (load_path_check): Now static.
5975 Fix some minor --with-ns problems found by static checking.
5976 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
5977 (x_set_font) [!HAVE_X_WINDOWS]:
5978 * image.c (xpm_load_image) [HAVE_NS]:
5979 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
5980 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
5981 Remove unused local.
5982 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
5983 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
5984 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
5985 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
5986 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
5987 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
5988 Fix pointer signedness problem.
5989 * xfaces.c (FRAME_X_FONT_TABLE):
5990 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
5992 2012-07-07 Glenn Morris <rgm@gnu.org>
5994 * lread.c (load_path_check): New function, split from init_lread.
5995 (init_lread): Reorganize. Motivation:
5996 If EMACSLOADPATH is set, check/warn about that rather than the
5997 defaults, which we are not going to use. Hence we can remove
5998 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
5999 Don't warn if site-lisp directories are missing.
6000 If not installed, start from a blank load-path, since
6001 PATH_LOADSEARCH refers to the eventual installation directories.
6003 2012-07-07 Eli Zaretskii <eliz@gnu.org>
6005 Support truncation and continuation glyphs on GUI frames, when
6006 fringes are disabled. (Bug#11832)
6007 * xdisp.c (init_iterator): Get dimensions of truncation and
6008 continuation glyphs even if on GUI frames.
6009 Adjust it->last_visible_x on GUI frames when the left or right fringes,
6010 or both, are absent.
6011 (start_display, move_it_in_display_line_to): Handle the case of a
6012 GUI frame without a fringe to display continuation or truncation
6014 (insert_left_trunc_glyphs): Support GUI frames: make sure
6015 truncation glyphs overwrite enough glyphs from the current line to
6016 have sufficient space in pixels.
6017 (display_line): Support truncation and continuation glyphs on GUI
6018 frames. If some spare pixels are left on the line after inserting
6019 the truncation glyphs, fill that space with a stretch glyph of a
6020 suitably computed width.
6022 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
6023 produce_glyphs, to support GUI sessions.
6025 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
6027 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
6029 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
6031 Do not require float-time's arg to fit in time_t (Bug#11825).
6032 This works better on hosts where time_t is unsigned, and where
6033 float-time is applied to the (negative) difference between two times.
6034 * editfns.c (decode_time_components): Last arg is now double *,
6035 not int *, and means to store all the result as a double, without
6036 worrying about whether the seconds part fits in time_t.
6037 All callers changed.
6038 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
6039 All callers changed.
6040 (Ffloat_time): Do not fail merely because the specified time falls
6041 outside of time_t range.
6043 2012-07-07 Glenn Morris <rgm@gnu.org>
6045 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

6052 Update dependencies.
6054 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
6056 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
6058 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).

6060 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
6061 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
6062 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.

6065 * xfont.c (compare_font_names): Redo to omit the need for casts.
6067 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
6069 * xfns.c (Fx_change_window_property): Doc fix.
6070 * w32fns.c (Fx_change_window_property): Doc fix.
6072 * w32fns.c (Fx_window_property): Accept the same arguments as the
6073 X Windows version. Doc fix.
6074 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
6076 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
6077 Eli Zaretskii <eliz@gnu.org>
6079 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
6080 Windows-specific code from nt/config.nt moved here.
6081 Obsolete settings removed.
6083 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
6085 * process.c: Avoid unnecessary calls to gettime.
6086 (wait_reading_process_output): Don't get the time of day
6087 when gobbling data immediately and not waiting, as there's no need
6088 for it in that case. This removes a FIXME.
6090 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
6092 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
6093 is defined (Bug#11768).
6095 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6097 Fix marker debugging code.
6098 * marker.c (byte_char_debug_check): Do not perform the check
6099 if buffer is not multibyte.
6100 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
6101 Call byte_char_debug_check with correct arguments.
6103 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6105 Compile marker debugging code only if ENABLE_CHECKING is defined.
6106 * marker.c (byte_char_debug_check, count_markers):
6107 Use only if ENABLE_CHECKING is defined.
6108 (byte_debug_flag): Remove.
6109 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
6110 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
6112 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6114 Avoid code repetition in marker-related functions.
6115 * marker.c (attach_marker): New function.
6116 (Fset_marker, set_marker_restricted, set_marker_both)
6117 (set_marker_restricted_both): Use it.
6118 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
6119 Consistently rename charno to charpos.

6140 * window.c (save_window_save): Likewise.
6142 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6144 Do not use Fdelete_overlay in delete_all_overlays
6145 to avoid redundant calls to unchain_overlay.
6146 * buffer.c (drop_overlay): New function.
6147 (delete_all_overlays, Fdelete_overlay): Use it.
6148 * minibuf.c (get_minibuffer): Fix comment.
6150 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
6152 Port to OpenBSD 5.1 amd64.
6153 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
6154 This is needed for OpenBSD, and should be harmless on all BSD systems.
6155 Also, include <sys/sysctl.h>, as it should be available on all
6156 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
6157 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
6158 use p_pid member, not kp_proc.pid.
6160 2012-07-06 Glenn Morris <rgm@gnu.org>
6162 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
6164 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>

6175 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
6177 Omit needless casts involving void * pointers and allocation.
6178 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
6179 as the former is more robust if P's type is changed.
6180 Prefer xzalloc to xmalloc + memset 0.
6181 Simplify malloc-or-realloc to realloc.
6182 Don't worry about xmalloc returning a null pointer.
6183 Prefer xstrdup to xmalloc + strcpy.
6184 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
6186 * keyboard.c (apply_modifiers_uncached): Prefer local array to
6187 alloca of a constant.
6189 2012-07-05 Eli Zaretskii <eliz@gnu.org>
6191 * xdisp.c (display_line): Fix horizontal pixel coordinates when
6192 hscroll is larger than the line width. Fixes long and futile
6193 looping inside extend_face_to_end_of_line (on a TTY) producing
6194 glyphs that are not needed and thrown away.
6196 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>

6224 * xdisp.c (window_hscroll_limited): New function.
6225 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
6226 coordinates when window's hscroll is set to insanely large
6229 2012-07-05 Juanma Barranquero <lekktu@gmail.com>

6298 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
6299 This should be fixed in a better way; see Eli Zaretskii in
6300 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
6301 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
6303 * fileio.c (time_error_value): Rename from special_mtime.
6304 The old name's problems were noted by Eli Zaretskii in
6305 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
6307 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
6308 This variable's comment says Emacs needs at least one GDB-visible
6309 symbol of type enum pvec_type, to work around GDB problems.
6310 The symbol's value doesn't matter.
6312 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
6313 that causes compilation to fail on pre-C99 compilers.
6315 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
6317 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
6318 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
6320 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
6322 * buffer.c (init_buffer_once): Fix initialization of
6323 headers for buffer_defaults and buffer_local_symbols.
6324 Reported by Juanma Barranquero <lekktu@gmail.com>.
6326 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
6328 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
6329 * lisp.h (enum pvec_type): Use fewer bits.
6330 (PSEUDOVECTOR_SIZE_BITS): New constant.
6331 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
6332 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
6333 change in pvec_type.
6334 (PSEUDOVECTOR_TYPEP): New macro.
6335 (TYPED_PSEUDOVECTORP): Use it.
6336 * fns.c (internal_equal): Adapt code to extract pvectype.
6337 * emacs.c (gdb_pvec_type): Update type.
6338 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
6339 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
6340 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
6341 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
6342 (sweep_vectors): Use it. Use local var `total_bytes' instead of
6343 abusing vector->header.next.nbytes.
6344 (live_vector_p): Use PVEC_TYPE.
6345 (mark_object): Adapt code to extract pvectype. Use switch.
6347 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
6349 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
6350 Tighten new eassert a bit.
6352 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
6354 Fix compilation with --enable-gcc-warnings and -O1
6356 * doprnt.c (doprnt): Change type of tem to int, initialize
6357 to avoid compiler warning. Add eassert.
6358 * search.c (simple_search): Initialize match_byte to avoid
6359 compiler warning. Add eassert.
6361 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
6363 Avoid weird behavior with large horizontal scrolls.
6364 Without this change, for example, large hscroll values would
6365 mess up Emacs's display on Fedora 15 x86, presumably due to
6366 overflows in int calculations in the display code.
6367 Also, if buffers had long lines, Emacs would freeze.
6368 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
6369 (set_window_hscroll): New function, containing the old guts of
6370 Fset_window_hscroll. Return the clipped value.
6371 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
6372 This avoids the need to check against PTRDIFF_MAX.
6374 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
6376 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
6378 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
6380 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
6382 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
6383 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
6384 since GCC 4.4.6 issues a bogus warning for them.
6386 Fix bugs in file timestamp newness comparisons.
6387 * fileio.c (Ffile_newer_than_file_p):
6388 * lread.c (Fload): Use full timestamp resolution of files,
6389 not just the 1-second resolution, so that files that are only
6390 slightly newer still count as newer.
6391 * fileio.c (Ffile_newer_than_file_p): Don't assume file
6392 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
6394 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
6396 * fileio.c: Improve handling of file time marker. (Bug#11852)
6397 (special_mtime): New function.
6398 (Finsert_file_contents, Fverify_visited_file_modtime):
6399 Use it to set special mtime values consistently.
6401 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
6403 * fileio.c (Finsert_file_contents): Properly handle st_mtime
6404 marker for non-existing file. (Bug#11852)
6406 2012-07-03 Glenn Morris <rgm@gnu.org>
6408 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
6409 and did not make it into globals.h).
6411 2012-07-03 Tom Tromey <tromey@redhat.com>
6413 * window.c (Fset_window_margins, Fset_window_fringes)
6414 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
6415 * textprop.c (Fprevious_property_change): No longer static.
6416 * syntax.c (Fsyntax_table_p): No longer static.
6417 * process.c (Fget_process, Fprocess_datagram_address): No longer
6419 * keymap.c (Flookup_key, Fcopy_keymap): No longer static.

6427 * doc.c (Fdocumentation_property, Fsnarf_documentation):
6429 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): No longer
6431 * dired.c (Ffile_attributes): No longer static.
6432 * composite.c (Fcomposition_get_gstring): No longer static.
6433 * callproc.c (Fgetenv_internal): No longer static.
6435 * ccl.h: Remove EXFUNs.
6436 * buffer.h: Remove EXFUNs.
6437 * dispextern.h: Remove EXFUNs.
6438 * intervals.h: Remove EXFUNs.
6439 * fontset.h: Remove EXFUN.
6440 * font.h: Remove EXFUNs.
6441 * dosfns.c (system_process_attributes): Remove EXFUN.
6442 * keymap.h: Remove EXFUNs.
6443 * lisp.h: Remove EXFUNs.
6444 * w32term.h: Remove EXFUNs.
6445 * window.h: Remove EXFUNs.
6446 * xsettings.h: Remove EXFUN.
6447 * xterm.h: Remove EXFUN.
6449 2012-07-03 Glenn Morris <rgm@gnu.org>
6451 * lisp.h (Frandom): Make it visible to C.
6452 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
6453 buffer for invisible buffers. (Bug#1229)
6455 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
6457 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
6458 values which aren't power of 2.
6459 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
6460 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
6463 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
6465 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
6467 * alloc.c (mark_object): Revert part of last patch to use `switch'.
6469 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
6471 * alloc.c (allocate_vector_block): Remove redundant
6472 calls to mallopt if DOUG_LEA_MALLOC is defined.
6473 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
6474 avoid calls to mallopt if zero_vector is returned.
6476 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
6478 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
6479 is enabled, avoid dereferencing NULL current_sblock if
6482 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
6484 Cleanup basic buffer management.
6485 * buffer.h (struct buffer): Change layout to use generic vector
6486 marking code. Fix some comments. Change type of 'clip_changed'
6487 to bitfield. Remove unused #ifndef old.
6488 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
6489 (GET_OVERLAYS_AT): Fix indentation.
6490 (for_each_per_buffer_object_at): New macro.
6491 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
6492 (Fbuffer_local_variables): Use it.
6493 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
6494 * alloc.c (allocate_buffer): Adjust to match new layout of
6495 struct buffer. Fix comment.
6496 (mark_overlay): New function.
6497 (mark_buffer): Use it. Use mark_vectorlike to mark normal
6498 Lisp area of struct buffer.
6499 (mark_object): Use it. Adjust marking of misc objects
6500 and related comments.
6502 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
6504 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
6505 wrapper that is not needed because the wrapped code is a no-op (zero
6506 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
6507 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
6509 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
6511 * alloc.c (mark_buffer): Simplify. Remove prototype.
6512 (mark_object): Add comment. Reorganize marking of vector-like
6513 objects. Use CHECK_LIVE for all vector-like objects except buffers
6514 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
6515 Avoid redundant calls to mark_vectorlike for bool vectors.
6517 2012-06-30 Glenn Morris <rgm@gnu.org>
6519 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
6521 * epaths.in (PATH_SITELOADSEARCH): New.
6522 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
6523 This is rather than relying on --enable-locallisppath elements
6524 having "site-lisp" in their names. (Bug#10208#25, 11658)
6526 2012-06-30 Eli Zaretskii <eliz@gnu.org>
6528 * w32proc.c (sys_select): Accept and ignore one more argument.
6530 * w32.c (emacs_gnutls_pull): Call select with one more argument.
6532 * sysselect.h [DOS_NT]: Don't include sys/select.h.
6533 (pselect) [!MS_DOS]: Redirect to sys_select.
6535 * sysdep.c: Don't include dos.h and dosfns.h.
6537 * process.c (sys_select):
6538 * msdos.c (sys_select): Accept one more argument and ignore it.
6540 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
6541 adapt data types and code to that.
6544 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
6545 which clashes with the gnulib function of the same name.
6547 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
6549 * font.c (font_style_to_value, font_style_symbolic)
6550 (font_prop_validate_style): Add type checks for values in
6553 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
6555 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
6558 2012-06-29 Eli Zaretskii <eliz@gnu.org>
6560 * xdisp.c (try_window_id): Undo last change.
6562 * w32.c (getwd): Adjust commentary about startup_dir.
6563 (init_environment): Always call sys_access, even in non-MSVC
6564 builds. Don't chdir to the directory of the Emacs executable.
6565 This undoes code from 1997 which was justified by the need to
6566 "avoid conflicts when removing and renaming directories". But its
6567 downside was that every relative file name was being interpreted
6568 relative to the directory of the Emacs executable, which can never
6569 be TRT. In particular, it broke sys_access when called with
6570 relative file names.
6571 (sys_access): Map GetLastError to errno.
6573 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
6575 * window.h (struct window): Change type of 'fringes_outside_margins'
6576 to bitfield. Fix comment. Adjust users accordingly.
6577 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
6579 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
6582 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
6584 * gnutls.c (emacs_gnutls_handshake):
6585 Add QUIT to make the loop interruptible.
6587 2012-06-29 Glenn Morris <rgm@gnu.org>
6589 * charset.c (init_charset): Make lack of etc/charsets fatal.
6591 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
6593 * editfns.c (region_limit): Fix type mismatch.
6595 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
6597 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
6598 undefined. Convert from xassert to eassert.
6599 * nsmenu.m: Convert from xassert to eassert.
6600 * nsterm.m: Likewise.
6602 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
6604 * editfns.c (region_limit): Clip to narrowing (bug#11770).
6606 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
6608 Avoid integer overflow on scroll-left and scroll-right.
6609 * window.c (HSCROLL_MAX): New macro.
6610 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
6611 overflow when requested scroll falls outside ptrdiff_t range.
6613 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
6615 * window.h (struct window): Change type of 'hscroll',
6616 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
6617 'last_modified' and 'last_overlay_modified' to EMACS_INT.
6618 Adjust users accordingly.
6619 * xdisp.c (try_cursor_movement): Replace type check with eassert.
6620 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
6621 from EMACS_INT to ptrdiff_t.
6622 (make_window): Omit redundant initialization.
6624 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
6626 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
6628 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
6630 * window.h (struct window): Change type of 'use_time' and
6631 'sequence_number' from Lisp_Object to int.
6632 * frame.c (make_frame): Adjust users accordingly.
6633 * print.c (print_object): Likewise.
6634 * window.c (select_window, Fwindow_use_time, make_parent_window)
6635 (make_window): Likewise.

6641 Fix GLYPH_DEBUG usage assuming that it may be undefined,
6642 adjust comments accordingly.
6643 * dispnew.c: Fix GLYPH_DEBUG usage assuming that it may be
6644 undefined, adjust comments accordingly.

6691 * alloc.c (allocate_string_data): Remove dead code.
6692 * xsettings.c (XSETTINGS_FONT_NAME): Move under HAVE_XFT to
6693 avoid GCC warning about unused macro.
6695 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
6697 * alloc.c (allocate_string): Omit intervals initialization.
6698 * alloc.c (make_uninit_multibyte_string): Initialize intervals
6699 as in make_pure_string and make_pure_c_string.
6701 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
6703 * alloc.c (allocate_string): Fix last change.
6705 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>

6755 * alloc.c: Remove build_string.
6756 * lisp.h: Define build_string as static inline. This provides
6757 a better opportunity to optimize away calls to strlen when the
6758 function is called with compile-time constant argument.
6759 * image.c (imagemagick_error): Convert to build_string.
6760 * w32proc.c (sys_spawnve): Likewise.
6761 * xterm.c (x_term_init): Likewise.
6763 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
6765 Use sprintf return value instead of invoking strlen on result.
6766 In the old days this wasn't portable, since some sprintf
6767 implementations returned char *. But they died out years ago and
6768 Emacs already assumes sprintf returns int.
6769 Similarly for float_to_string.
6770 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
6771 * ccl.c (ccl_driver):
6772 * character.c (string_escape_byte8):

6775 * print.c (print_object):
6776 * xdisp.c (message_dolog):
6777 * xfns.c (syms_of_xfns):
6778 Use sprintf or float_to_string result to avoid need to call strlen.
6779 * data.c (Fnumber_to_string):
6780 Use make_unibyte_string, since the string must be ASCII.
6781 * lisp.h, print.c (float_to_string): Now returns int length.
6782 * term.c (produce_glyphless_glyph):
6783 Use sprintf result rather than recomputing it.
6785 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
6786 * Makefile.in (ALL_CFLAGS):
6787 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

6884 * keyboard.c (kbd_buffer_get_event):
6885 * process.c (Faccept_process_output):
6886 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
6887 This improves on the previous patch, which introduced a bug
6888 when time_t is unsigned and as wide as intmax_t.
6889 See <http://bugs.gnu.org/9000#51>.
6891 2012-06-23 Eli Zaretskii <eliz@gnu.org>

6954 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
6956 Support higher-resolution time stamps (Bug#9000).
6957 The time stamps are only nanosecond-resolution at the C level,
6958 since that's the best that any real-world system supports now.
6959 But they are picosecond-resolution at the Lisp level, as that's
6960 easy, and leaves room for future OS improvements.
6962 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
6965 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
6966 Don't get current time unless it's needed.
6968 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
6969 now provides it if it's absent.
6970 (start_atimer): Port to higher-res time stamps.
6971 Check for time stamp overflow. Don't get current time more
6972 often than is needed.
6974 * buffer.h (struct buffer): Buffer modtime now has high resolution.
6975 Include systime.h, not time.h.
6976 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
6978 * dired.c: Include stat-time.h.
6979 (Ffile-attributes): File times now have higher resolution.

6982 (struct image): Timestamp now has higher resolution.
6984 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
6985 has at least microseconds now. All uses removed.
6986 (update_frame, update_single_window, update_window, update_frame_1)
6987 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
6988 (duration_to_sec_usec): Remove; no longer needed.
6990 * editfns.c (time_overflow): Now extern.

6992 (float-time, Fformat_time_string, Fcurrent_time_string)
6993 (Fcurrent_time_zone): Accept and generate higher-resolution
6995 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
6996 (decode_time_components, lisp_seconds_argument): New functions.
6997 (make_time): Now static.
6998 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
6999 Report an error if the time is invalid, rather than having the caller
7002 * fileio.c: Include <stat-time.h>
7003 (Fcopy_file): Copy higher-resolution time stamps.
7004 Prefer to set the time stamp via a file descriptor if that works.

7006 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
7007 (Fvisited_file_modtime, Fset_visited_file_modtime):
7008 Support higher-resolution time stamps.
7010 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
7012 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
7014 * image.c (prepare_image_for_display, clear_image_cache)
7015 (lookup_image): Port to higer-resolution time stamps.
7017 * keyboard.c (start_polling, bind_polling_period):
7018 Check for time stamp overflow.
7019 (read_char, kbd_buffer_get_event, timer_start_idle)
7020 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
7021 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
7022 Port to higher-resolution time stamps. Do not assume time_t is signed.
7023 (decode_timer): New function. Timers are now vectors of length 9,
7024 not 8, to accommodate the picosecond component.
7025 (timer_check_2): Use it.
7027 * nsterm.m (select_timeout, timeval_subtract): Remove.
7028 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
7029 as they're a bit more accurate and handle overflow better.
7030 (ns_select): Change prototype to be compatible with pselect.
7031 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
7032 * nsterm.h (ns_select): Adjust prototype.
7034 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
7035 us-resolution time stamps.
7036 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
7038 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
7040 * lisp.h (time_overflow): New decl.
7041 (wait_reading_process_output): First arg is now intmax_t, not int,
7042 to accommodate larger waits.
7044 * process.h (struct Lisp_Process.read_output_delay):
7045 Now counts nanoseconds, not microseconds.
7046 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
7048 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
7049 (wait_reading_process_output):
7050 Port to ns-resolution time stamps.
7051 (Faccept_process_output, wait_reading_process_output):
7052 Check for time stamp overflow. Do not assume time_t is signed.
7053 (select_wrapper): Remove; we now use pselect.
7054 (Fprocess_attributes): Now generates ns-resolution time stamps.
7056 * sysdep.c: Include utimens.h. Don't include utime.h
7057 or worry about struct utimbuf; gnulib does that for us now.
7058 (gettimeofday): Remove; gnulib provides a substitute.
7059 (make_timeval): New function.
7060 (set_file_times): Now sets ns-resolution time stamps.
7061 New arg FD; all uses changed.
7062 (time_from_jiffies, ltime_from_jiffies, get_up_time)
7063 (system_process_attributes):
7064 Now returns ns-resolution time stamp. All uses changed.
7065 Check for time stamp overflow.
7067 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
7068 provides a substitute now.
7070 * systime.h: Include timespec.h rather than sys/time.h and time.h,
7071 since it guarantees struct timespec.
7072 (EMACS_TIME): Now struct timespec, so that we can support
7073 ns-resolution time stamps.
7074 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
7075 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
7076 (EMACS_USECS): Remove.
7077 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
7078 so multiply the arg by 1000 before storing it.
7079 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
7081 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
7082 Port to ns-resolution time stamps.
7083 (EMACS_TIME_NEG_P): Remove; replaced by....
7084 (EMACS_TIME_SIGN): New macro.
7085 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
7086 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
7087 (set_file_times, make_time, lisp_time_argument): Adjust signature.
7088 (make_timeval, make_lisp_time, decode_time_components): New decls.
7089 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
7090 that it mishandled time_t overflow. You can't compare by subtracting!
7091 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
7092 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
7094 * term.c: Include <sys/time.h>.

7103 (w32_get_internal_run_time):
7104 Port to higher-resolution Emacs time stamps.
7105 (ltime): Now accepts single 64-bit integer, as that's more convenient
7108 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
7110 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
7111 for compatibility with pselect. Support ns-resolution time stamps.
7113 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
7115 * xselect.c (wait_for_property_change, x_get_foreign_selection):
7116 Check for time stamp overflow, and support ns-resolution time stamps.
7118 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
7119 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
7120 (timeval_subtract): Remove; no longer needed.
7121 (XTflash, XTring_bell, x_wait_for_event):
7122 Port to ns-resolution time stamps. Don't assume time_t is signed.
7124 2012-06-22 Chong Yidong <cyd@gnu.org>
7126 * xdisp.c (x_consider_frame_title): Revert last change.
7128 2012-06-22 Eli Zaretskii <eliz@gnu.org>
7130 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
7131 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
7132 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
7133 staticidx goes up to 1597 out of 1600 = 0x640.)
7135 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
7137 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
7138 Otherwise, the umask might be mistakenly 0 while handling input signals.

7159 (unwind_format_mode_line): Restore them.
7160 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
7162 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
7163 since tty frames can be explicitly named.
7164 (prepare_menu_bars): Likewise.
7166 * term.c (Ftty_top_frame): New function.
7168 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

7171 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
7172 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
7173 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
7174 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
7175 (METER_1, METER_2): Simplify.
7177 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
7179 * data.c (Fdefalias): Return `symbol' (bug#11686).
7181 2012-06-18 Martin Rudalics <rudalics@gmx.at>
7183 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
7184 gets killed during executing of this function (Bug#11665).
7185 Try to always return Qt when the buffer has been actually killed.
7186 (Vkill_buffer_query_functions): In doc-string say that functions
7187 run by this hook should not change the current buffer.
7189 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
7191 Fix recently-introduced process.c problems found by static checking.
7192 * process.c (write_queue_push, write_queue_pop, send_process):

7195 (send_process): Remove unused local.
7197 2012-06-17 Chong Yidong <cyd@gnu.org>

7200 frames that are not on top.
7202 2012-06-17 Troels Nielsen <bn.troels@gmail.com>
7204 * process.c (make_process): Initialize write_queue.
7205 (write_queue_push, write_queue_pop): New functions.

7209 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
7211 * lisp.h (eassert): Assume C89 or later.
7212 This removes the need for CHECK.
7213 (CHECK): Remove. Its comments about always evaluating its
7214 argument were confusing, as 'eassert' typically does not evaluate
7217 * coding.c (produce_chars): Use ptrdiff_t, not int.
7219 * xterm.c (x_draw_underwave): Check for integer overflow.
7220 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

7405 code works fine either way, and efficiency is not a concern here,
7406 as the union type is for debugging, not for production.
7407 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
7408 Use an inline function on all platforms when using the union type,
7409 since this is simpler and 'static inline' can be used portably

7553 * doprnt.c (doprnt): Truncate multibyte char correctly.
7554 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
7555 would mishandle a string argument "Xc" if X was a multibyte

7610 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
7611 Convert pctcpu and pctmem to Lisp float properly.
7612 Let the compiler fold better, as 100.0/0x8000 is exact.

7616 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of

7631 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
7632 fields from Lisp_Object to bitfield. Adjust users accordingly.

7640 and 'double' in a couple of places.
7642 2012-05-31 Eli Zaretskii <eliz@gnu.org>
7644 * xdisp.c (handle_stop): Detect whether we have overlay strings
7645 loaded by testing it->current.overlay_string_index to be
7646 non-negative, instead of checking whether n_overlay_strings is
7647 positive. (Bug#11587)
7649 2012-05-31 Chong Yidong <cyd@gnu.org>
7651 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

7657 * search.c (search_buffer): Remove calls to

7659 maybe_unify_char, which was the cause of relocation of buffer text
7662 2012-05-31 Eli Zaretskii <eliz@gnu.org>
7664 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
7665 for the duration of call to load_charset, to avoid problems with
7666 callers of maybe_unify_char that access buffer text through C
7669 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
7670 decrement the inhibition flag, instead of just setting or
7673 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
7675 Remove obsolete '#define static' cruft.
7676 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
7677 This #undef was "temporary" in 2000; it is no longer needed

7679 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
7680 (gray_bitmap_bits): Remove; no longer needed.
7681 All uses replaced with definiens.

7725 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
7726 Bug#9642, but explicitly check that the buffer the overlay would
7727 be moved to is live and rearrange lines to make sure that errors
7728 will not put the overlay in an inconsistent state.
7729 (Fdelete_overlay): Cosmetics.
7731 2012-05-28 Eli Zaretskii <eliz@gnu.org>
7733 * w32term.c (my_bring_window_to_top): New function.

7735 could be different from the original one.
7736 Call my_bring_window_to_top instead of my_set_foreground_window.
7739 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
7740 by calling BringWindowToTop.
7742 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
7743 (WM_EMACS_END): Increase by one.
7745 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
7747 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
7748 This avoids undefined behavior that might cause the eassert
7749 to not catch an out-of-range value.
7751 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
7753 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
7754 Update dependencies.

7763 when referring to sectname field in printf format.
7765 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
7767 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
7768 Only r_alloc_inhibit_buffer_relocation needed to be added;
7769 the others were already declared.
7771 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
7772 before checking whether it's out of range. Put the check inside
7774 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
7776 2012-05-27 Ken Brown <kbrown@cornell.edu>
7778 * callproc.c (Fcall_process): Restore a line that was accidentally
7779 commented out in the 2011-02-13 change (bug#11547).
7781 2012-05-27 Eli Zaretskii <eliz@gnu.org>
7783 * lisp.h [REL_ALLOC]: Add prototypes for external functions
7784 defined on ralloc.c.
7786 * buffer.c [REL_ALLOC]: Remove prototypes of
7787 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
7788 they are now on lisp.h.
7790 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
7792 * search.c (search_buffer): Use it to inhibit relocation of buffer
7793 text while re_search_2 is doing its job, because re_search_2 is
7794 passed C pointers to buffer text. (Bug#11519)
7796 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
7799 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
7800 state after an additional call to move_it_in_display_line_to, keep
7801 the values of it->max_ascent and it->max_descent found for the
7803 (pos_visible_p): Revert the comparison against bottom_y to what it
7804 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
7807 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
7809 Fix coding-related core dumps with gcc -ftrapv.
7810 The code was computing A - B, where A and B are pointers, and B is
7811 random garbage. This can lead to core dumps on platforms that
7812 have special pointer registers, and it also leads to core dumps on
7813 x86-64 when compiled with gcc -ftrapv. The fix is to compute
7814 A - B only when B is initialized properly.
7815 * coding.c (coding_set_source, coding_set_destination): Return void.
7816 (coding_change_source, coding_change_destinations): New functions,
7817 with the old behaviors of coding_set_source and coding_set_destination.
7818 All callers that need an offset changed to use these new functions.
7820 2012-05-26 Glenn Morris <rgm@gnu.org>
7822 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
7824 2012-05-26 Eli Zaretskii <eliz@gnu.org>
7826 Extend mouse support on W32 text-mode console.
7827 * xdisp.c (draw_row_with_mouse_face):
7828 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
7830 * w32console.c: Include window.h.
7831 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
7833 (initialize_w32_display): Initialize mouse-highlight data.
7835 * w32inevt.c: Include termchar.h and window.h.
7836 (do_mouse_event): Support mouse-autoselect-window. When the mouse
7837 moves, call note_mouse_highlight. If help_echo changed, call
7838 gen_help_event to produce help-echo message in the echo area.
7839 Call clear_mouse_face if mouse_face_hidden is set in the mouse
7842 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
7844 * lread.c (read1): Simplify slightly to avoid an overflow warning
7845 with GCC 4.7.0 on x86-64.
7847 2012-05-26 Eli Zaretskii <eliz@gnu.org>
7849 * bidi.c (bidi_mirror_char): Revert last change: an int is
7850 definitely wide enough here.
7852 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
7854 Fix integer width and related bugs (Bug#9874).

7862 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
7864 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
7865 (allocate_pseudovector):
7866 Use int, not EMACS_INT, where int is wide enough.
7867 (inhibit_garbage_collection, Fgarbage_collect):
7868 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
7869 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
7870 int might not be wide enough.
7871 (bidi_cache_search, bidi_cache_find, bidi_init_it)

7885 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
7886 (Foverlay_recenter, last_overlay_modification_hooks_used)
7887 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
7888 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
7889 (validate_region): Omit unnecessary test for b <= e,
7890 since that's guaranteed by the previous test.
7891 (adjust_overlays_for_delete): Avoid pos + length overflow.
7892 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
7893 (report_overlay_modification):
7894 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
7895 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
7896 Omit pointer cast, which isn't needed anyway, and doesn't work
7897 after the EMACS_INT -> ptrdiff_t change.
7898 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
7899 * buffer.h: Adjust decls to match defn changes elsewhere.

7904 not int, to avoid needless 32-bit limit on 64-bit hosts.
7905 (exec_byte_code): Use tighter memory-full test, one that checks
7906 for alloca overflow. Don't compute the address of the object just
7907 before an array, as that's not portable. Use EMACS_INT, not
7908 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
7909 * callint.c (Fcall_interactively):
7910 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

7921 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
7922 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
7923 (casify_object): Avoid integer overflow when overallocating buffer.
7924 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
7925 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
7926 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
7927 * category.h (CATEGORYP): Don't assume arg is nonnegative.
7928 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
7929 integers are now checked earlier. All uses replaced with XINT.
7931 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
7932 For CCL_MapSingle, check that content and value are in int range.
7933 (ccl_driver, Fregister_code_conversion_map):
7934 Check that Vcode_version_map_vector is a vector.
7935 (resolve_symbol_ccl_program): Check that vector header is in range.
7936 Always copy the vector, so that we can check its contents reliably
7937 now rather than having to recheck each instruction as it's being
7938 executed. Check that vector words fit in 'int'.
7939 (ccl_get_compiled_code, Fregister_ccl_program)
7940 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
7941 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
7942 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
7943 contents are in range.
7944 (Fccl_execute_on_string): Check that status is in range.
7945 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
7946 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
7947 Accept and return EMACS_INT, not int, because callers can pass values
7949 (c_string_width, strwidth, lisp_string_width, chars_in_text)

7953 (string_escape_byte8, Fget_byte):
7954 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
7955 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
7956 avoid mishandling large integers.
7957 * character.h: Adjust decls to match defn changes elsewhere.

7966 (Fdefine_charset_internal): Check ranges here, more carefully.
7967 Don't rely on undefined behavior with signed left shift overflow.
7968 Don't assume unsigned int fits into fixnum, or that fixnum fits
7969 into unsigned int. Don't require max_code to be a valid fixnum;
7970 that's not true for gb10830 4-byte on a 32-bit host. Allow
7971 invalid_code to be a cons, for the same reason. Require code_offset
7972 to be a character. Avoid int overflow if max_char is close
7974 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
7975 this is intended anyway and avoids some undefined behavior.
7976 (load_charset_map): Pass unsigned, not int, as 2nd arg of
7977 INDEX_TO_CODE_POINT, as that's what it expects.
7978 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
7979 * charset.h (DECODE_CHAR): Return int, not unsigned;
7980 this is what was intended anyway, and it avoids undefined behavior.
7981 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
7982 integer-overflow issues.
7983 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
7984 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
7985 where the argument is EMACS_INT, and this behavior is not intended.
7986 * chartab.c (Fmake_char_table, Fset_char_table_range)
7987 (uniprop_get_decoder, uniprop_get_encoder):
7988 Don't assume fixnum fits in int.
7989 * cmds.c (move_point): New function, that does the gist of
7990 Fforward_char and Fbackward_char, but does so while checking
7991 for integer overflow more accurately.
7992 (Fforward_char, Fbackward_char): Use it.
7993 (Fforward_line, Fend_of_line, internal_self_insert)
7994 (internal_self_insert):
7995 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
7996 Fix a FIXME, by checking for integer overflow when calculating
7997 target_clm and actual_clm.

8032 Don't access memory outside of the args array.
8033 (Fdefine_coding_system_internal): Check for charset-id overflow.

8794 already have overlays loaded.
8795 (handle_single_display_spec): Before returning without displaying
8796 fringe bitmap, synchronize the bidi iterator with the main display
8797 iterator, by calling iterate_out_of_display_property.
8798 (iterate_out_of_display_property): Detect buffer iteration by
8799 testing that it->string is a Lisp string.
8800 (get_next_display_element): When the current object is exhausted,
8801 and there's something on it->stack, call set_iterator_to_next to

8804 proceed to consider_string_end without incrementing string
8805 position. Don't increment display vector index past the end of
8806 the display vector. (Bug#11417)
8807 (pos_visible_p): Don't report a position visible when move_it_to
8808 stopped at the last line of window, which happens to be scanned
8809 backwards by the bidi iteration. (Bug#11464)
8811 2012-05-14 Eli Zaretskii <eliz@gnu.org>
8813 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
8814 and right-margin display specs even if the spec is invalid or we
8815 are on a TTY, and thus unable to display on the fringes.
8816 That's because the text with the property will not be displayed anyway,
8817 so we need to signal to the caller that this is a "replacing"
8818 display spec. This fixes display when the spec is invalid or we
8821 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
8823 * unexaix.c (make_hdr): Fix typo in prototype.

8868 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
8870 * dbusbind.c (xd_registered_buses): New internal Lisp object.
8871 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
8872 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
8873 Initialize xd_registered_buses.
8875 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
8877 Untag more efficiently if USE_LSB_TAG.
8878 This is based on a proposal by YAMAMOTO Mitsuharu in
8879 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
8880 For an admittedly artificial (nth 8000 longlist) benchmark on
8881 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
8882 Emacs's overall text size by 1%.
8883 * lisp.h (XUNTAG): New macro.
8884 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
8885 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
8886 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
8887 * eval.c (Fautoload):
8888 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
8889 * frame.h (XFRAME): Use XUNTAG.
8891 Port recent dbusbind.c changes to 32-bit --with-wide-int.
8892 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
8893 Remove unportable assumptions about print widths of types like
8895 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
8896 intptr_t when converting between pointer and integer, to avoid GCC
8897 warnings about wrong width.
8899 2012-05-09 Eli Zaretskii <eliz@gnu.org>
8901 * w32proc.c (new_child): Force Windows to reserve only 64KB of
8902 stack for each reader_thread, instead of defaulting to 8MB
8903 determined by the linker. This avoids failures in creating
8904 subprocesses on Windows 7, see the discussion in this thread:
8905 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
8907 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
8909 Fix up display of the *Minibuf-0* buffer in the mini window.
8910 * keyboard.c (read_char): Don't clear the echo area if there's no
8912 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
8913 contents of *Minibuf-0*) if there's no message displayed in its stead.
8915 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
8917 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
8920 2012-05-06 Chong Yidong <cyd@gnu.org>
8922 * lisp.mk (lisp): Update.
8924 2012-05-05 Jim Meyering <meyering@redhat.com>
8926 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
8928 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
8930 * data.c (PUT_ERROR): New macro.
8931 (syms_of_data): Use it. Add new error type `user-error'.
8932 * undo.c (user_error): New function.
8933 (Fprimitive_undo): Use it.
8934 * print.c (print_error_message): Adjust print style for `user-error'.
8935 * keyboard.c (user_error): New function.
8936 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
8938 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
8940 Do not limit current-time-string to years 1000..9999.
8941 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
8942 (Fcurrent_time_string): Support any year that is supported by the
8943 underlying localtime representation. Don't use asctime, as it
8944 has undefined behavior for years outside the range -999..9999.
8946 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
8948 Fix race conditions involving setenv, gmtime, localtime, asctime.
8949 Without this fix, interrupts could mess up code that uses these
8950 nonreentrant functions, since setting TZ invalidates existing
8951 tm_zone or tzname values, and since most of these functions return
8952 pointers to static storage.
8953 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
8954 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
8955 Grow the critical sections to include not just invoking
8956 localtime/gmtime, but also accessing these functions' results
8957 including their tm_zone values if any, and any related TZ setting.
8958 (format_time_string): Last arg is now struct tm *, not struct tm **,
8959 so that the struct tm is saved in the critical section.
8960 All callers changed. Simplify allocation of initial buffer, partly
8961 motivated by the fact that memory allocation needs to be outside
8962 the critical section.
8964 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
8966 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
8967 with RESET_INTERVAL.
8969 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
8970 Remove duplicated buffer name initialization.
8972 2012-05-02 Jim Meyering <jim@meyering.net>
8974 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
8976 * xfns.c (x_window): Use xstrdup (Bug#11375).
8978 2012-05-02 Eli Zaretskii <eliz@gnu.org>
8980 * xdisp.c (pos_visible_p): If already at a newline from the
8981 display string before the 'while' loop, don't walk back the glyphs
8982 from it3.glyph_row. Solves assertion violation when the display
8983 string begins with a newline (egg.el). (Bug#11367)
8985 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
8987 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
8990 2012-05-01 Glenn Morris <rgm@gnu.org>
8992 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
8993 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
8994 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
8995 All were removed before 23.1.
8997 * dispnew.c: Remove HAVE_LIBNCURSES test;
8998 it is always true on relevant platforms.
9000 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
9001 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
9003 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
9005 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
9007 * .gdbinit (xpr): Remove checks for no longer existing misc types.
9008 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
9011 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
9013 Do not avoid creating empty evaporating overlays (Bug#9642).
9014 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
9015 That is, do not delete an evaporating overlay if it becomes
9016 empty after its bounds are adjusted to fit within its buffer.
9017 This fix caused other problems, and I'm reverting it until we get
9018 to the bottom of them.
9020 2012-04-27 Chong Yidong <cyd@gnu.org>
9022 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
9024 2012-04-27 Eli Zaretskii <eliz@gnu.org>
9026 * xdisp.c (pos_visible_p): If the window start position is beyond
9027 ZV, start the display from buffer beginning. Prevents assertion
9028 violation in init_iterator when the minibuffer window is scrolled
9031 * window.c (window_scroll_pixel_based): Likewise.
9033 2012-04-27 Chong Yidong <cyd@gnu.org>
9035 * keymap.c (where_is_internal): Doc fix (Bug#10872).
9037 2012-04-27 Glenn Morris <rgm@gnu.org>
9039 * fileio.c (Fcopy_file, Fset_file_selinux_context):
9040 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
9042 2012-04-27 Eli Zaretskii <eliz@gnu.org>
9044 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
9045 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
9047 2012-04-26 Eli Zaretskii <eliz@gnu.org>
9049 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
9050 display element, check also the underlying string or buffer
9051 character. (Bug#11341)
9053 * w32menu.c: Include w32heap.h.
9054 (add_menu_item): If the call to AppendMenuW (via
9055 unicode_append_menu) fails, disable Unicode menus only if we are
9056 running on Windows 9X/Me.
9058 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
9060 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
9061 (xgetint): Add missing shift for LSB tags.
9063 2012-04-24 Martin Rudalics <rudalics@gmx.at>
9065 * keyboard.c (read_char): Don't wipe echo area for select window
9066 events: These might get delayed via `mouse-autoselect-window'
9069 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
9071 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
9072 manipulation of :loaded-from data.
9074 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
9076 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
9077 now a cons (bug#11311).
9079 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
9081 Do not create empty overlays with the evaporate property (Bug#9642).
9082 * buffer.c (Fmove_overlay): Delete an evaporating overlay
9083 if it becomes empty after its bounds are adjusted to fit within
9084 its buffer. Without this fix, in a nonempty buffer (let ((o
9085 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
9086 yields an empty overlay that has the evaporate property, which is
9087 not supposed to happen.
9089 Fix minor GTK3 problems found by static checking.
9090 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
9091 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
9092 (struct _EmacsFixedClass, emacs_fixed_get_type):

9102 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
9104 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
9105 Problem reported by Juanma Barranquero for Windows -Wunused-function.
9107 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
9109 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
9110 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
9111 (__malloc_size_t, __malloc_ptrdiff_t):
9112 Remove. All uses removed, replaced by the definiens if needed,
9113 since we can assume C89 or better now.
9114 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
9115 (protect_malloc_state, align, get_contiguous_space)
9116 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)

9122 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
9123 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
9124 Define using prototypes, not old style.
9125 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
9126 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
9127 (align): Don't assume that signed integer overflow wraps around.
9128 Omit unused local var.
9129 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
9130 (_free_internal_nolock, memalign, mallochook, reallochook):

9134 (struct hdr): The 'magic' member is now size_t, not unsigned long.
9136 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
9138 2012-04-22 Michael Albinus <michael.albinus@gmx.de>

9189 * alloc.c: Handle unusual debugging option combinations.
9190 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,

9204 * sysdep.c [__FreeBSD__]: Minor cleanups.
9205 (list_system_processes, system_process_attributes) [__FreeBSD__]:
9206 Use Emacs indenting style more consistently. Avoid some casts.
9207 Use 'double' consistently rather than mixing 'float' and 'double'.

9248 farther than the first row after the header line, if any.
9249 Don't consider the header-line row as "partially visible", even if
9250 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)

9305 (r_alloc_free) [REL_ALLOC]: Move decls from here ...
9306 * lisp.h (r_alloc, r_alloc_free, r_re_alloc, r_alloc_reset_variable)
9307 [REL_ALLOC]: ... to here, to check interface.
9308 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
9309 Remove decls. This fixes an "It stinks!".
9311 * alloc.c (which_symbols): Fix alignment issue / type clash.
9313 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
9315 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
9316 (struct Lisp_Misc_Any): Likewise.
9317 (struct Lisp_Free): Likewise.
9318 * alloc.c (union aligned_Lisp_Symbol): Define.
9319 (SYMBOL_BLOCK_SIZE, struct symbol_block): Use union
9320 aligned_Lisp_Symbol instead of struct Lisp_Symbol.

9322 (MARKER_BLOCK_SIZE, struct marker_block): Use union
9323 aligned_Lisp_Misc instead of union Lisp_Misc.
9324 (Fmake_symbol, allocate_misc, gc_sweep): Adjust.
9326 2012-04-14 Paul Eggert <eggert@cs.ucla.edu>
9328 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
9329 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
9330 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
9331 * s/netbsd.h, s/sol2-6.h:
9332 Remove definition of GC_MARK_STACK, since the default now works.
9333 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
9334 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
9335 no longer the default.
9336 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
9338 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
9340 * lread.c (lisp_file_lexically_bound_p):
9341 Fix hang at ";-*-\n" (bug#11238).

9348 2012-04-14 Jan Djärv <jan.h.d@swipnet.se>
9350 * nsterm.m (constrainFrameRect): Always constrain when there is only
9351 one screen (Bug#10962).
9353 2012-04-13 Ken Brown <kbrown@cornell.edu>
9355 * s/cygwin.h (PTY_OPEN): Don't try to close a bogus file descriptor.
9357 2012-04-13 Reuben Thomas <rrt@sc3d.org>
9359 * indent.c (Fmove_to_column): Change interactive spec (Bug#739).
9361 2012-04-11 Daniel Colascione <dancol@dancol.org>
9363 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
9364 against is gone. It's better to use vfork now so that when Cygwin
9365 gains a new, working vfork, we use it automatically (bug#10398).
9367 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
9369 * window.c (save_window_save): Obey window-point-insertion-type.
9371 2012-04-11 Glenn Morris <rgm@gnu.org>
9373 * Makefile.in (GNUSTEP_CFLAGS): Rename from C_SWITCH_X_SYSTEM.
9375 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
9377 * alloc.c (lisp_align_malloc): Remove unneeded prototype.
9379 2012-04-10 Jason S. Cornez <jcornez@ravenpack.com> (tiny change)
9381 * keyboard.c: Override inhibit-quit after the third C-g (bug#6585).
9382 (force_quit_count): New var.
9383 (handle_interrupt): Use it.
9385 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
9387 * w32.c (w32_delayed_load): Record the full path of the library
9388 being loaded (bug#10424).
9390 2012-04-09 Glenn Morris <rgm@gnu.org>
9392 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
9393 not just in the obarray, before snarfing them. (Bug#11036)
9395 * Makefile.in ($(leimdir)/leim-list.el):
9396 Pass EMACS rather than BUILT_EMACS.
9398 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
9400 * process.c (make_process):
9401 * process.h: Add integer `gnutls_handshakes_tried' member to
9404 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.
9405 Add convenience `GNUTLS_LOG2i' macro.
9407 * gnutls.c (gnutls_log_function2i): Convenience log function.
9408 (emacs_gnutls_read): Use new log functions,
9409 `gnutls_handshakes_tried' process member, and
9410 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
9411 attempts per process (connection).
9413 2012-04-09 Chong Yidong <cyd@gnu.org>
9415 * eval.c (Fuser_variable_p, user_variable_p_eh)
9416 (lisp_indirect_variable): Functions deleted.
9417 (Fdefvar): Caller changed.
9419 * callint.c (Finteractive, Fcall_interactively):
9420 * minibuf.c (Fread_variable): Callers changed.
9422 2012-04-09 Eli Zaretskii <eliz@gnu.org>
9424 * xdisp.c (set_cursor_from_row): If the display string appears in
9425 the buffer at position that is closer to point than the position
9426 after the display string, display the cursor on the first glyph of
9427 the display string. Fixes cursor display when a 'display' text
9428 property immediately follows invisible text. (Bug#11094)
9430 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
9432 composite.c: use 'double' consistently
9433 * composite.c (get_composition_id): Use 'double' consistently
9434 instead of converting 'float' to 'double' and vice versa; this is
9435 easier to understand and avoids a GCC warning.
9437 2012-04-09 Glenn Morris <rgm@gnu.org>
9439 * Makefile.in: Generate leim-list with bootstrap-emacs, in
9440 preparation for dumping it with emacs. (Bug#4789)
9441 (leimdir): New variable.
9442 ($(leimdir)/leim-list.el): New rule.
9443 (emacs$(EXEEXT)): Depend on leim-list.el.

9449 2012-04-08 Andreas Schwab <schwab@linux-m68k.org>
9451 * lisp.h (struct Lisp_Symbol): Add explicit padding to ensure
9454 2012-04-07 Juanma Barranquero <lekktu@gmail.com>
9456 * xml.c (init_libxml2_functions) [WINDOWSNT]:
9457 Remove unused local variable.
9459 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
9461 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
9462 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
9463 (mark_memory): Mark Lisp_Objects only if pointers might hide in
9464 objects, as mark_maybe_pointer will catch them otherwise.
9465 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
9466 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
9468 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
9470 Fix typo that broke non-Windows builds.
9471 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.
9473 2012-04-07 Eli Zaretskii <eliz@gnu.org>
9475 Support building on MS-Windows with libxml2.
9477 * makefile.w32-in (OBJ2): Add xml.$(O).
9478 (GLOBAL_SOURCES): Add xml.c.
9479 ($(BLD)/xml.$(O)): New dependency list.
9481 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
9482 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
9483 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
9484 [!WINDOWSNT]: New macros.
9485 (init_libxml2_functions, libxml2_loaded_p): New functions.
9486 (parse_region): Call fn_xmlCheckVersion instead of using the macro
9487 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
9488 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
9489 Calls xmlCleanupParser only if libxml2 was loaded (or statically
9491 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
9492 Call init_libxml2_functions before calling libxml2 functions.
9493 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
9495 * emacs.c: Don't include libxml/parser.h.
9496 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
9497 xmlCleanupParser directly.
9499 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
9501 2012-04-07 Eli Zaretskii <eliz@gnu.org>
9503 * indent.c (Fvertical_motion): If there is a display string at
9504 point, use it.vpos to compute how many lines to backtrack after
9505 move_it_to point. (Bug#11133)
9507 2012-04-06 Eli Zaretskii <eliz@gnu.org>
9509 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
9510 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
9511 about subtle differences between FETCH_CHAR* and STRING_CHAR*
9512 macros related to unification of CJK characters. For the details,
9513 see the discussion following the message here:
9514 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
9516 2012-04-04 Chong Yidong <cyd@gnu.org>
9518 * keyboard.c (Vdelayed_warnings_list): Doc fix.
9520 2012-04-01 Eli Zaretskii <eliz@gnu.org>
9522 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
9523 instead of alloca. (Bug#11138)
9525 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
9527 * w32menu.c (is_simple_dialog): Properly check lisp types.
9530 2012-03-31 Eli Zaretskii <eliz@gnu.org>
9532 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
9533 position we get to after a call to move_it_to fails the
9534 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
9535 only if we wind up in a string from display property. (Bug#11063)
9537 * window.c (Fdelete_other_windows_internal): Invalidate the row
9538 and column information about mouse highlight, so that redisplay
9539 restores it after reallocating the glyph matrices. (Bug#7464)
9541 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
9542 string comes from a `display' text property, use the buffer
9543 position of that property as if we actually saw that position in
9545 (move_it_by_lines): Remove the assertion that
9546 "it->current_x == 0 && it->hpos == 0" which can be legitimately
9547 violated when there's a before-string at the beginning of a line.
9550 2012-03-30 Eli Zaretskii <eliz@gnu.org>
9552 * xdisp.c (append_space_for_newline): If the default face was
9553 remapped, use the remapped face for the appended newline.
9554 (extend_face_to_end_of_line): Use the remapped default face for
9555 extending the face to the end of the line.
9556 (display_line): Call extend_face_to_end_of_line when the default
9557 face was remapped. (Bug#11068)
9559 2012-03-29 Eli Zaretskii <eliz@gnu.org>
9561 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
9563 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
9565 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
9567 2012-03-27 Glenn Morris <rgm@gnu.org>
9569 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
9572 2012-03-26 Kenichi Handa <handa@m17n.org>
9574 * dispextern.h (struct glyph): Fix previous change. Change the
9575 bit length of glyphless.ch to 25 (Bug#11082).
9577 2012-03-26 Chong Yidong <cyd@gnu.org>
9579 * keyboard.c (Vselection_inhibit_update_commands): New variable.
9580 (command_loop_1): Use it; inhibit selection update for
9581 handle-select-window too (Bug#8996).
9583 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
9585 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
9587 2012-03-25 Kenichi Handa <handa@m17n.org>
9589 * dispextern.h (struct glyph): Change the bit length of
9590 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
9592 2012-03-24 Eli Zaretskii <eliz@gnu.org>
9594 * s/ms-w32.h (tzname): Include time.h before redirecting to
9595 _tzname. Fixes the MSVC build. (Bug#9960)
9597 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
9599 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
9602 * xterm.c (XTread_socket): Only modify handling_signal if
9603 !SYNC_INPUT. (Bug#11080)
9605 2012-03-23 Eli Zaretskii <eliz@gnu.org>
9607 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
9608 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
9609 when fetching a multibyte character consumes more bytes than
9610 CHAR_BYTES returns, due to unification of CJK characters in
9611 string_char. (Bug#11073)
9613 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
9615 * process.c (wait_reading_process_output): Handle pty disconnect
9616 by refraining from sending oneself a SIGCHLD (bug#10933).
9618 2012-03-22 Chong Yidong <cyd@gnu.org>
9620 * dispextern.h (struct it): New member string_from_prefix_prop_p.
9622 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
9623 Mark string as coming from a prefix property.
9624 (handle_face_prop): Use default face for prefix strings (Bug#4281).
9625 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
9627 2012-03-21 Chong Yidong <cyd@gnu.org>
9629 * xfaces.c (Vface_remapping_alist): Doc fix.
9631 2012-03-20 Eli Zaretskii <eliz@gnu.org>
9633 * w32proc.c (Fw32_set_console_codepage)
9634 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
9637 2012-03-20 Chong Yidong <cyd@gnu.org>
9639 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
9640 to reflect default non-nil value of redisplay-dont-pause.
9642 2012-03-19 Kenichi Handa <handa@m17n.org>
9644 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
9645 it fit in a valid range (Bug#11003).
9647 2012-03-18 Eli Zaretskii <eliz@gnu.org>
9649 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
9650 that is not from display property, accept the row as a "cursor
9651 row" if one of the string's character has a non-nil `cursor'
9652 property. Fixes cursor positioning when there are newlines in
9653 overlay strings, e.g. in icomplete.el. (Bug#11035)
9655 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
9657 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
9659 2012-03-12 Chong Yidong <cyd@gnu.org>
9661 * eval.c (inhibit_lisp_code): Rename from
9662 inhibit_window_configuration_change_hook; move from window.c.
9664 * xfns.c (unwind_create_frame_1, Fx_create_frame):
9665 * window.c (run_window_configuration_change_hook)
9666 (syms_of_window): Callers changed.
9668 2012-03-11 Chong Yidong <cyd@gnu.org>
9670 * keymap.c (Fkey_description): Doc fix (Bug#9700).
9672 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
9674 2012-03-10 Chong Yidong <cyd@gnu.org>
9676 * frame.c (other_visible_frames): Don't assume the selected frame
9677 is visible (Bug#10955).
9679 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
9681 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
9683 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
9685 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
9686 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
9689 2012-03-03 Glenn Morris <rgm@gnu.org>
9691 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
9693 2012-03-02 Eli Zaretskii <eliz@gnu.org>
9695 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
9696 position past the first glyph_row that ends at ZV. (Bug#10902)
9697 (redisplay_window, next_element_from_string): Fix typos in
9699 (redisplay_window): Pass to move_it_vertically the margin in
9700 pixels, not in screen lines.
9702 2012-03-02 Glenn Morris <rgm@gnu.org>
9704 * buffer.c (buffer-list-update-hook): Doc fix.
9706 2012-02-29 Eli Zaretskii <eliz@gnu.org>
9708 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
9709 push_it before setting up the iterator for the first overlay
9710 string, even if we have an empty string loaded.
9711 (next_overlay_string): If there's an empty string on the iterator
9712 stack, pop the stack. (Bug#10903)
9714 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
9716 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
9717 Suggested by Stefan Monnier in
9718 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
9719 * alloc.c (widen_to_Lisp_Object): New static function.
9720 (mark_memory): Also mark Lisp_Objects by fetching pointer words
9721 and widening them to Lisp_Objects. This would work even if
9722 USE_LSB_TAG is defined and wide integers are used, which might
9723 happen in a future version of Emacs.
9725 2012-02-25 Chong Yidong <cyd@gnu.org>
9727 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
9730 * xselect.c (Fx_selection_exists_p): Doc fix.
9731 (x_clipboard_manager_save_all): Print an informative message
9732 before saving to clipboard manager.
9734 2012-02-24 Chong Yidong <cyd@gnu.org>
9736 * keyboard.c (process_special_events): Handle all X selection
9737 requests in kbd_buffer, not just the next one (Bug#8869).
9739 2012-02-23 Chong Yidong <cyd@gnu.org>
9741 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
9742 call when setting menu-bar-lines and tool-bar-lines parameters.
9743 (unwind_create_frame_1): New helper function.
9745 * window.c (inhibit_window_configuration_change_hook): New var.
9746 (run_window_configuration_change_hook): Obey it.
9747 (syms_of_window): Initialize it.
9749 2012-02-22 Chong Yidong <cyd@gnu.org>
9751 * xterm.c (x_draw_image_relief): Add missing type check for
9752 Vtool_bar_button_margin (Bug#10743).
9754 2012-02-21 Chong Yidong <cyd@gnu.org>
9756 * fileio.c (Vfile_name_handler_alist): Doc fix.
9758 * buffer.c (Fget_file_buffer): Protect against invalid file
9759 handler return value.
9761 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
9763 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
9764 when computing $valmask.
9766 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
9767 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
9768 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
9769 It's useless in that case, and it can cause problems on hosts
9770 that allocate halves of EMACS_INT values separately.
9771 Reported by Dan Horák. Diagnosed by Andreas Schwab in
9772 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
9773 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
9774 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
9775 it avoids undefined behavior on hosts where shifting right by more
9776 than the word width has undefined behavior.
9778 2012-02-19 Chong Yidong <cyd@gnu.org>
9780 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
9781 (Funhandled_file_name_directory, Ffile_name_as_directory)
9782 (Fdirectory_file_name, Fexpand_file_name)
9783 (Fsubstitute_in_file_name): Protect against invalid file handler
9784 return values (Bug#10845).
9786 2012-02-18 Eli Zaretskii <eliz@gnu.org>
9788 * .gdbinit (pitx): Fix incorrect references to fields of the
9791 2012-02-17 Chong Yidong <cyd@gnu.org>
9793 * syntax.c (Fscan_lists): Doc fix (Bug#10833).
9795 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>

10393 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
10394 verifies glyph row's hash code--we have just reallocated the

10560 is set, removing the need for VIRT_ADDRESS_VARIES.
10561 (PURE_P): Use a more-efficient implementation that needs just one

10568 consistency with the new puresize.h.
10569 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
10570 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

10577 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
10578 behave as if the cursor position were at the window margin.
10580 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
10581 and the cursor position is out of bounds, behave as if the cursor
10582 position were at the window margin. (Bug#10075)
10584 2011-11-18 Chong Yidong <cyd@gnu.org>
10586 * window.c (Fwindow_combination_limit): Make first argument

10608 compute_line_metrics.
10609 (compute_line_metrics): Call row_hash, instead of computing the
10612 * dispnew.c (verify_row_hash): Call row_hash for computing the
10613 hash code of a row, instead of duplicating code from xdisp.c.
10615 * dispextern.h (row_hash): Add prototype.
10617 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
10619 * frame.c (delete_frame): Don't delete the terminal when the last

10668 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
10669 with user-defined heap size. Bump the default size of the temacs

10673 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
10674 current_matrix and desired_matrix. (Bug#9990)
10675 (verify_row_hash) [XASSERTS]: New function.

10722 Avoid some portability problems by eschewing 'extern inline' functions.
10723 The trivial performance wins aren't worth the portability hassles; see
10724 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
10726 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

10755 * w32.c (check_windows_init_file): Don't look for term/w32-win.el
10756 if Vpurify_flag is non-nil. Fixes a crash when running w32 build
10757 of temacs in GUI mode.
10759 2011-11-07 Martin Rudalics <rudalics@gmx.at>
10761 * window.h: Declare delete_all_child_windows instead of

10767 (Fdelete_other_windows_internal, Fset_window_configuration):
10768 Call delete_all_child_windows instead of delete_all_subwindows.
10769 * frame.c (delete_frame): Call delete_all_child_windows instead
10770 of delete_all_subwindows.
10772 2011-11-07 Paul Eggert <eggert@cs.ucla.edu>
10774 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
10775 This is also needed for porting to any host where GC_MARK_STACK is
10776 not GC_MAKE_GCPROS_NOOPS.
10777 (which_symbols): Use it.
10779 2011-11-07 Kenichi Handa <handa@m17n.org>
10781 * coding.c (coding_set_destination): Check coding->src_pos only
10782 when coding->src_object is a buffer (bug#9910).

10792 * xmenu.c (cleanup_widget_value_tree): New function.
10793 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
10794 calling free_menubar_widget_value_tree directly (Bug#9830).
10796 2011-11-06 Paul Eggert <eggert@cs.ucla.edu>
10798 Fix some portability problems with 'inline'.

10800 (window_box_width, window_box_left, window_box_left_offset)
10801 (window_box_right, window_box_right_offset): Declare extern.
10802 Otherwise, these inline functions do not conform to C99 and
10803 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
10804 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
10805 * intervals.c (adjust_intervals_for_insertion)
10806 (adjust_intervals_for_deletion): Now extern, because otherwise the
10807 extern inline functions 'offset_intervals' couldn't refer to it.
10808 (static_offset_intervals): Remove.
10809 (offset_intervals): Rewrite using the old contents of
10810 static_offset_intervals. The old version didn't conform to C99
10811 because an extern inline function contained a reference to an
10812 identifier with static linkage.
10814 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>

10834 (Fwindow_vscroll): Doc fix.
10835 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
10836 argument, since it makes no sense to pass a live window and for
10837 consistency with window-child.

10865 (unwind_create_frame): New function (Bug#9943).
10866 (Fx_create_frame): Restructure code to be more similar to the one in
10867 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).
10868 Initialize image_cache_refcount if GLYPH_DEBUG (Bug#9943).
10869 Move terminal->reference_count++ just before making the frame official

10877 Move terminal->reference_count++ just before making the frame
10878 official. Move initialization of image_cache_refcount and
10879 dpyinfo_refcount before calling init_frame_faces (Bug#9943).

10919 previous/next-single-property-change returns nil, treat that as
10920 the beginning or the end of the buffer. (Bug#9955)
10922 2011-11-04 Jan Djärv <jan.h.d@swipnet.se>
10924 * gtkutil.c (xg_make_tool_item): Add callbacks if one of wimage or

11047 (w32font_open_internal, compute_metrics):
11048 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
11049 instead of calling the "wide" APIs directly.
11051 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
11053 * w32.h (syms_of_w32font): Add prototype.
11055 2011-10-27 Juanma Barranquero <lekktu@gmail.com>

11062 2011-10-27 Chong Yidong <cyd@gnu.org>
11064 * process.c (make_process): Set gnutls_state to NULL.
11066 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
11067 non-NULL, regardless of GNUTLS_INITSTAGE.

11116 (bidi_resolve_weak): Don't enter the expensive loop if the current
11117 position is before next_en_pos. Record the bidi type of the first
11118 non-ET, non-BN character we find, in addition to its position.
11119 (bidi_level_of_next_char): Invalidate next_en_type when
11120 next_en_pos is over-stepped.
11122 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
11124 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
11125 * editfns.c: Rewrite current-time-zone so that it invokes
11126 the equivalent of (format-time-string "%Z") to get the time zone name.
11127 This fixes a bug when the time zone name contains characters that
11128 need converting from the system time locale to Emacs internal format.
11129 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
11130 that patch fixed format-time-string to do the conversion, but
11131 I forgot to fix current-time-zone.
11132 (format_time_string): New function, containing most of
11133 what Fformat_time_string used to contain.
11134 (Fformat_time_string): Rewrite in terms of format_time_string.
11135 This doesn't change this function's behavior.
11136 (current-time-zone): Rewrite to use format_time_string.
11137 This fixes the bug reported by Michael Schierl in
11138 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
11139 Jason Rumney's 2007-06-07 change worked around this bug, but
11141 * systime.h (tzname, timezone): Remove no-longer-used declarations.
11143 2011-10-19 Eli Zaretskii <eliz@gnu.org>
11145 * xdisp.c (start_display): If the character at POS is displayed
11146 via a display vector, reset IT->current.dpvec_index to zero.
11147 (try_window_reusing_current_matrix): If a line ends in a display
11148 vector or the next line starts in a display vector, continue
11149 redrawing the window even though the character position of
11150 start_row was reached.
11153 2011-10-18 Chong Yidong <cyd@gnu.org>
11155 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
11156 with nobreak-char-display too.
11158 2011-10-18 Eli Zaretskii <eliz@gnu.org>
11160 Fix part 3 of bug#9771.
11161 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
11162 (bidi_resolve_neutral): Don't enter the expensive loop looking for
11163 non-neutral characters if the current character is a paragraph
11164 separator (a.k.a. Newline). This avoids running the same
11165 expensive loop twice, once when we consume the preceding newline
11166 and the other time when the line actually needs to be displayed.
11167 Avoid the loop when we see neutrals on the base embedding level
11168 following a character whose directionality is the same as the
11169 paragraph's. This avoids running the expensive loop when a line
11170 ends in a long sequence of neutrals, like control characters.
11171 Add assertion against STRONG_AL type. Slightly rearrange code
11172 that determines the type of a neutral given the first non-neutral
11174 (bidi_level_of_next_char): Set next_en_pos to zero when
11175 invalidating its info.
11177 2011-10-17 Eli Zaretskii <eliz@gnu.org>
11179 * xdisp.c (push_display_prop): Determine whether to record string
11180 or buffer position by IT->string, not by IT->method. Allow
11181 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
11182 (move_it_vertically_backward): Don't look for character position
11183 immediately after the newline when in a continuation line.
11186 2011-10-15 Martin Rudalics <rudalics@gmx.at>
11188 * window.c (coordinates_in_window): Rewrite and delabelize
11189 vertical border check. (Bug#5357) (Bug#9618)
11191 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
11193 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
11194 errors in XSetWindowBorder (bug#9310).
11196 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
11198 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
11199 avoid crash when xmalloc overrun checking is enabled.
11201 2011-10-13 Eli Zaretskii <eliz@gnu.org>
11203 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
11204 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
11205 cursor motion with <left> and <right> arrow keys.
11207 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
11208 some callers set that themselves.
11210 2011-10-12 Eli Zaretskii <eliz@gnu.org>
11212 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
11213 display string and the previous row comes from the same string and
11214 is empty. (Bug#9739) (Bug#9738)
11216 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
11218 * doc.c (get_doc_string): Encode file name (bug#9735).
11220 2011-10-12 Eli Zaretskii <eliz@gnu.org>
11222 * bidi.c (bidi_level_of_next_char):
11223 * xdisp.c (get_visually_first_element): Remove old incorrect
11224 comments regarding the Unicode Line Separator character.
11226 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
11228 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
11230 * alloc.c (Fgc_status): Do not access beyond zombies array
11231 boundary if nzombies > MAX_ZOMBIES.
11232 * alloc.c (dump_zombies): Add missing format specifier.
11234 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
11236 * xdisp.c (set_cursor_from_row): Simplify conditionals,
11237 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
11239 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
11240 Some packages use them to denote characters with modifiers.
11242 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
11244 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
11245 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
11246 matching a pp-number. Rename parameter var to var1.
11248 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
11250 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
11252 2011-10-08 Glenn Morris <rgm@gnu.org>
11254 * callint.c (Fcall_interactively): Give a more explicit error for the
11255 'c' case with a non-character input. (Bug#8479)
11257 2011-10-08 Eli Zaretskii <eliz@gnu.org>
11259 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
11261 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
11262 lines that are hscrolled on the left.
11264 * dispnew.c (buffer_posn_from_coords): Account for a possible
11265 presence of header-line. (Bug#4426)
11267 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
11269 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
11270 Don't advertise functionality which we discourage or doesn't work.
11272 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
11274 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
11275 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
11276 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
11277 this makes Emacs dump core during garbage collection on rare
11278 occasions. sizeof is obviously inferior to offsetof here, so
11279 stick with offsetof.
11280 (GC_POINTER_ALIGNMENT): New macro.
11281 (mark_memory): Omit 3rd (offset) arg; caller changed.
11282 Don't assume EMACS_INT alignment is the same as pointer alignment.
11284 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
11286 * keyboard.c (read_key_sequence_remapped): New var.
11287 (read_key_sequence): Compute remapping in the right buffer.
11288 (command_loop_1): Use read_key_sequence's remapping directly.
11290 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
11292 * dired.c (file_name_completion): Don't expand file name.
11293 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
11294 before checking file name handler.
11296 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
11297 they've been requested explicitly (bug#9591).
11299 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
11301 * keymap.c (Fsingle_key_description): Use make_specified_string
11302 instead of build_string to build string from push_key_description.
11305 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
11307 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
11308 This fixes a Y2038 bug on 64-bit hosts.
11309 * buffer.c (reset_buffer):
11310 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
11311 (Fclear_buffer_auto_save_failure):
11312 Use 0, not -1, to represent an unset failure time, since time_t
11313 might not be signed.
11315 Remove dependency on glibc malloc internals.
11316 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11317 Move back here from lisp.h, but with their new implementations.
11318 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
11319 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
11320 * charset.c (charset_table_init): New static var.
11321 (syms_of_charset): Use it instead of xmalloc. This removes a
11322 dependency on glibc malloc internals. See Eli Zaretskii's comment in
11323 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
11324 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11325 Move back to alloc.c.
11326 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
11327 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
11329 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
11331 * nsterm.m (windowDidResize): Call x_set_window_size only when
11332 ns_in_resize is true. Otherwise set pixelwidth/height and
11333 call change_frame_size (Bug#9628).
11335 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
11337 Port --enable-checking=all to Fedora 14 x86-64.
11338 * charset.c (syms_of_charset): Also account for glibc malloc's
11339 internal overhead when calculating the initial malloc maximum.
11341 Port --enable-checking=all to Fedora 14 x86.
11342 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11344 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
11345 (overrun_check_realloc, overrun_check_free):
11346 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
11347 That way, xmalloc returns a properly-aligned pointer even if
11348 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
11349 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
11350 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
11351 into account when calculating the initial malloc maximum.
11352 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11353 Move here from alloc.c, so that charset.c can use it too.
11354 Properly align; the old code wasn't right for common 32-bit hosts
11355 when configured with --enable-checking=all.
11356 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
11357 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
11359 2011-09-29 Eli Zaretskii <eliz@gnu.org>
11361 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
11364 2011-09-28 Eli Zaretskii <eliz@gnu.org>
11366 * xdisp.c (compute_display_string_end): If there's no display
11367 string at CHARPOS, return -1.
11369 * bidi.c (bidi_fetch_char): When compute_display_string_end
11370 returns a negative value, treat the character as a normal
11371 character not covered by a display string. (Bug#9624)
11373 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
11375 * lread.c (Fread_from_string): Fix typo in docstring.
11377 2011-09-27 Eli Zaretskii <eliz@gnu.org>
11379 * xdisp.c (handle_invisible_prop): If invisible text ends on a
11380 newline, reseat the iterator instead of bidi-iterating there one
11381 character at a time. (Bug#9610)
11382 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
11383 TO_CHARPOS if the bidi iterator is at base embedding level.
11385 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
11387 * lread.c (readevalloop): Use correct code for NBSP.
11388 (read1): Likewise. (Bug#9608)
11390 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
11392 * dbusbind.c (Fdbus_register_signal): When service is not
11393 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
11395 2011-09-25 Glenn Morris <rgm@gnu.org>
11397 * buffer.c (truncate-lines): Doc fix.
11399 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
11401 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
11402 (Fset_window_next_buffers): Doc fix.
11404 2011-09-24 Glenn Morris <rgm@gnu.org>
11406 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
11408 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
11410 Fix minor problems found by static checking.
11411 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
11412 * indent.c (Fvertical_motion): Fix == vs = typo.
11414 2011-09-24 Eli Zaretskii <eliz@gnu.org>
11416 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
11417 Default value is now t. Doc fix.
11419 * indent.c (Fvertical_motion): Compute and apply the overshoot
11420 logic when moving up, not only when moving down. Fix the
11421 confusing name and values of the it_overshoot_expected variable;
11422 logic changes accordingly. (Bug#9254) (Bug#9549)
11424 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
11425 CHARPOS is covered by a display string which includes newlines.
11426 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
11427 is covered by a display string with embedded newlines.
11429 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
11431 * dbusbind.c (Fdbus_register_signal): Add match rule to
11432 Vdbus_registered_objects_table. (Bug#9581)
11433 (Fdbus_register_method, Vdbus_registered_objects_table):
11436 2011-09-24 Jim Meyering <meyering@redhat.com>
11438 do not ignore write error for any output size
11439 The previous change was incomplete.
11440 While it makes emacs --batch detect the vast majority of stdout
11441 write failures, errors were still ignored whenever the output size is
11442 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
11443 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
11444 && echo FAIL: ignored write error
11445 FAIL: ignored write error
11446 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
11447 && echo FAIL: ignored write error
11448 FAIL: ignored write error
11449 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
11451 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
11453 * emacs.c (Fkill_emacs): In noninteractive mode exit
11454 non-successfully if a write error occurred on stdout. (Bug#9574)
11456 2011-09-21 Eli Zaretskii <eliz@gnu.org>
11458 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
11461 * dispextern.h (struct it): Update the comment documenting what
11464 2011-09-20 Eli Zaretskii <eliz@gnu.org>
11466 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
11467 a display string, extend search for cursor position to end of row.
11468 (find_row_edges): If the row ends in a newline from a display
11469 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
11470 Handle the case of a display string with multiple newlines.
11471 (Fcurrent_bidi_paragraph_direction): Fix search for previous
11472 non-empty line. Fixes confusing cursor motion with arrow keys at
11473 the beginning of a line that starts with whitespace.
11475 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
11477 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
11480 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
11482 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
11483 boolean (Bug#9154).
11485 2011-09-18 Eli Zaretskii <eliz@gnu.org>
11487 * xdisp.c (display_line): Record maximum and minimum buffer
11488 positions even if no glyphs were produced (e.g., by a zero-width
11489 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
11490 buffer positions that will be removed from the glyph row because
11492 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
11493 column is beyond frame width: don't subtract 1 "pixel" when
11494 computing width of the stretch.
11495 (reseat_at_next_visible_line_start): Undo the change made on
11496 2011-09-17 that saved paragraph information and restored it after
11497 the call to `reseat'. (Bug#9545)
11499 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11501 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
11502 and turn window cursor on if cleared (Bug#9415).
11504 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
11506 * search.c (boyer_moore): Take unibyte characters from pattern
11507 literally. (Bug#9458)
11509 2011-09-18 Eli Zaretskii <eliz@gnu.org>
11511 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
11513 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
11515 Fix minor problem found by static checking.
11516 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
11517 initialized, to pacify gcc -Wuninitialized.
11519 * fileio.c: Report proper errno when syscall falls.
11520 (Finsert_file_contents): Save and restore errno,
11521 so that report_file_error outputs the correct diagnostic.
11522 (Fwrite_region) [CLASH_DETECTION]: Likewise.
11524 2011-09-18 Eli Zaretskii <eliz@gnu.org>
11526 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
11528 2011-09-17 Eli Zaretskii <eliz@gnu.org>
11530 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
11531 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
11533 2011-09-17 Eli Zaretskii <eliz@gnu.org>
11535 * xdisp.c (reseat_at_next_visible_line_start): Keep information
11536 about the current paragraph and restore it after the call to reseat.
11538 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
11539 (bidi_find_paragraph_start): Search back for paragraph beginning
11540 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
11541 (bidi_move_to_visually_next): Only trigger paragraph-related
11542 computations when the last character is a newline or at EOB, not
11543 just any NEUTRAL_B. (Bug#9470)
11545 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
11546 truncated lines if point is covered by a display string. (Bug#9524)
11548 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
11550 * xselect.c: Relax test for outgoing X longs (Bug#9498).
11551 (cons_to_x_long): New function.
11552 (lisp_data_to_selection_data): Use it. Correct the test for
11553 short-versus-long data; it was negated. Break out of vector
11554 loop, for efficiency, when a long datum is discovered.
11556 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
11558 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
11560 2011-09-16 Eli Zaretskii <eliz@gnu.org>
11562 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
11563 GCC PR/17406) by declaring this function with external scope.
11565 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
11567 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).

11570 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
11572 * editfns.c (Fformat): Correctly handle text properties on "%%".
11574 2011-09-15 Eli Zaretskii <eliz@gnu.org>
11576 * xterm.c (x_draw_composite_glyph_string_foreground):
11577 * w32term.c (x_draw_composite_glyph_string_foreground):
11578 * term.c (encode_terminal_code):
11579 * composite.c (composition_update_it, get_composition_id):
11580 * xdisp.c (get_next_display_element)
11581 (fill_composite_glyph_string): Add comments about special meaning
11582 of TAB characters in a composition.
11584 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
11586 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
11587 This occurs when processing a multibyte format.
11588 Problem reported by Wolfgang Jenker.
11590 2011-09-15 Johan Bockgård <bojohan@gnu.org>
11592 * xdisp.c (try_cursor_movement): Only check for exact match if
11593 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
11595 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
11597 Remove unused external symbols.
11598 * dispextern.h (calc_pixel_width_or_height): Remove decl.
11599 * xdisp.c (calc_pixel_width_or_height): Now static.
11600 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
11601 * indent.c (check_display_width):
11602 * w32term.c: Fix comment to match code.
11603 * xterm.c, xterm.h (x_catching_errors): Remove.
11605 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
11607 * xselect.c: Use signed conversions more consistently (Bug#9498).
11608 (selection_data_to_lisp_data): Assume incoming selection data are
11609 signed integers, not unsigned. This is to be consistent with
11610 outgoing selection data, which was modified to use signed integers
11611 in as part of the fix to Bug#9196 in response to Jan D.'s comment
11612 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
11613 expects long, not unsigned long.
11615 2011-09-14 Eli Zaretskii <eliz@gnu.org>
11617 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
11618 computation of loop end. Reported by Johan Bockgård

11625 2011-09-12 Eli Zaretskii <eliz@gnu.org>
11627 * indent.c (compute_motion): Process display vector front to back
11628 rather than the other way around. (Bug#2496)
11630 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
11632 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
11634 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
11636 * minibuf.c (Fread_from_minibuffer): Doc fix.
11638 2011-09-11 Eli Zaretskii <eliz@gnu.org>
11640 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
11641 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
11643 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>

11646 value for non-existent files.
11648 2011-09-11 Eli Zaretskii <eliz@gnu.org>
11650 * fileio.c (Finsert_file_contents): If the file cannot be opened,
11651 set its "size" to -1. This will set the modtime_size field of
11652 the corresponding buffer to -1, which is what
11653 verify-visited-file-modtime expects for files that do not exist.
11656 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
11658 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
11660 * lisp.h: ... from here. push_key_description is no longer
11661 defined in keyboard.c, so its declaration should not be in
11662 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
11663 logically belongs with push_key_description.
11665 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
11667 * buffer.h: Include <sys/types.h> instead of <time.h>.
11668 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
11669 Problem reported by Herbert J. Skuhra.
11671 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
11673 * xml.c (parse_region): Make the parsing work for
11674 non-comment-starting XML files again (bug#9144).
11676 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
11678 * image.c (gif_load): Fix calculation of bottom and right corner.
11681 2011-09-10 Eli Zaretskii <eliz@gnu.org>
11683 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
11684 redisplay in small windows.
11686 2011-09-09 Eli Zaretskii <eliz@gnu.org>
11688 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
11690 2011-09-08 Martin Rudalics <rudalics@gmx.at>
11692 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
11693 Operate on live windows only.
11695 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
11697 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
11699 2011-09-07 Eli Zaretskii <eliz@gnu.org>
11701 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
11702 only under bidi iteration.
11704 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
11706 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
11708 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
11710 isnan: Fix porting problem to Solaris 10 with bundled gcc.
11711 Without this fix, the command to link temacs failed due to an
11712 undefined symbol __builtin_isnan. This is because
11713 /usr/include/iso/math_c99.h #defines isnan(x) to
11714 __builtin_isnan(x), but the bundled gcc, which identifies itself
11715 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
11717 * floatfns.c (isnan): #undef, and then #define to a clone of
11719 (Fisnan): Always define, since it's always available now.
11720 (syms_of_floatfns): Always define isnan at the Lisp level.
11722 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
11724 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
11726 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
11728 * fileio.c: Fix bugs with large file offsets (Bug#9428).
11729 The previous code assumed that file offsets (off_t values) fit in
11730 EMACS_INT variables, which is not true on typical 32-bit hosts.
11731 The code messed up by falsely reporting buffer overflow in cases
11732 such as (insert-file-contents "big" nil 1 2) into an empty buffer
11733 when "big" contains more than 2**29 bytes, even though this
11734 inserts just one byte and does not overflow the buffer.
11735 (Finsert_file_contents): Store file offsets as off_t
11736 values, not as EMACS_INT values. Check for overflow when
11737 converting between EMACS_INT and off_t. When checking for
11738 buffer overflow or for overlap, take the offsets into account.
11739 Don't use EMACS_INT for small values where int suffices.
11740 When checking for overlap, fix a typo: ZV was used where
11741 ZV_BYTE was intended.
11742 (Fwrite_region): Don't assume off_t fits into 'long'.
11743 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
11745 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
11747 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
11749 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
11751 sprintf-related integer and memory overflow issues (Bug#9412).
11753 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
11754 (esprintf, exprintf, evxprintf): New functions.
11755 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
11756 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
11757 (modify_event_symbol): Do not assume that the length of
11758 name_alist_or_stem is safe to alloca and fits in int.
11759 (Fexecute_extended_command): Likewise for function name and binding.
11760 (Frecursion_depth): Wrap around reliably on integer overflow.
11761 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
11762 since some callers pass EMACS_INT values.
11763 (Fsingle_key_description): Don't crash if symbol name contains more
11764 than MAX_ALLOCA bytes.
11765 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
11766 (get_minibuffer): Arg is now EMACS_INT, not int.
11767 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
11768 (esprintf, exprintf, evxprintf): New decls.
11769 * window.h (command_loop_level, minibuf_level): Reflect API changes.
11771 * dbusbind.c (signature_cat): New function.
11772 (xd_signature, Fdbus_register_signal):
11773 Do not overrun buffer; instead, report string overflow.
11775 * dispnew.c (add_window_display_history): Don't overrun buffer.
11776 Truncate instead; this is OK since it's just a log.
11778 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
11779 even if the time zone offset is outlandishly large.
11780 Don't mishandle offset == INT_MIN.
11782 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
11783 when creating daemon; the previous buffer-overflow check was incorrect.
11785 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
11786 which has the guts of the old verror function.
11788 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
11789 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
11791 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
11792 (font_unparse_xlfd): Don't blindly alloca long strings.
11793 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
11794 fits in int, when using sprintf. Use single snprintf to count
11795 length of string rather than counting it via multiple sprintfs;
11796 that's simpler and more reliable.
11797 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
11798 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
11799 sprintf, in case result does not fit in int.
11801 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
11802 (fontset_from_font): Print it.
11804 * frame.c (tty_frame_count): Now printmax_t, not int.
11805 (make_terminal_frame, set_term_frame_name): Print it.
11806 (x_report_frame_params): In X, window IDs are unsigned long,
11807 not signed long, so print them as unsigned.
11808 (validate_x_resource_name): Check for implausibly long names,
11809 and don't assume name length fits in 'int'.
11810 (x_get_resource_string): Don't blindly alloca invocation name;
11811 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
11814 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
11815 (xg_check_special_colors, xg_set_geometry):
11816 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
11818 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
11819 Use esprintf, not sprintf, in case result does not fit in int.
11821 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
11822 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
11823 it as a large positive number.
11824 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
11825 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
11827 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
11828 in case result does not fit in int.
11830 * print.c (float_to_string): Detect width overflow more reliably.
11831 (print_object): Make sprintf buffer a bit bigger, to avoid potential
11832 buffer overrun. Don't assume list length fits in 'int'. Treat
11833 print length of 0 as 0, not as infinity; to be consistent with other
11834 uses of print length in this function. Don't overflow print length
11835 index. Don't assume hash table size fits in 'long', or that
11836 vectorlike size fits in 'unsigned long'.
11838 * process.c (make_process): Use printmax_t, not int, to format
11839 process-name gensyms.
11841 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
11843 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
11844 to avoid potential buffer overrun.
11846 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
11847 if X resource line is longer than 512 bytes.
11849 * xfns.c (x_window): Make sprintf buffer a bit bigger
11850 to avoid potential buffer overrun.
11852 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
11854 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
11856 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
11858 Integer overflow fixes for scrolling, etc.
11859 Without these, Emacs silently mishandles large integers sometimes.
11860 For example, "C-u 4294967297 M-x recenter" was treated as if
11861 it were "C-u 1 M-x recenter" on a typical 64-bit host.
11863 * xdisp.c (try_window_id): Check Emacs fixnum range before
11864 converting to 'int'.
11866 * window.c (window_scroll_line_based, Frecenter):
11867 Check that an Emacs fixnum is in range before assigning it to 'int'.
11868 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
11869 values converted from Emacs fixnums.
11870 (Frecenter): Don't wrap around a line count if it is out of 'int'
11871 range; instead, treat it as an extreme value.
11872 (Fset_window_configuration, compare_window_configurations):
11873 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
11875 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
11876 that can exceed INT_MAX. Check that EMACS_INT value is in range
11877 before assigning it to the (possibly-narrower) index.
11878 (match_limit): Don't assume that a fixnum can fit in 'int'.
11880 * print.c (print_object): Use ptrdiff_t, not int, for index that can
11883 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
11884 (Fvertical_motion): Don't wrap around LINES values that don't fit
11885 in 'int'. Instead, treat them as extreme values. This is good
11886 enough for windows, which can't have more than INT_MAX lines anyway.
11888 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
11890 * Require libxml/parser.h to avoid compilation warning.
11892 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
11894 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
11895 since this reportedly can destroy thread storage.
11897 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
11899 * syntax.c (find_defun_start): Update all cache variables if
11900 exiting early (Bug#9401).
11902 2011-08-30 Eli Zaretskii <eliz@gnu.org>
11904 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
11906 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
11907 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
11908 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
11910 * term.c (tty_append_glyph): New function.
11911 (produce_stretch_glyph): Static function and its prototype deleted.
11913 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
11916 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
11918 * image.c (parse_image_spec): Check for nonnegative, not for positive,
11919 when checking :margin (Bug#9390).
11920 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
11921 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
11922 so that the name doesn't mislead. All uses changed.
11924 2011-08-28 Johan Bockgård <bojohan@gnu.org>
11926 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
11929 2011-08-27 Eli Zaretskii <eliz@gnu.org>
11931 * xdisp.c (move_it_to): Don't bail out early when reaching
11932 position beyond to_charpos, if we are scanning backwards.
11933 (move_it_vertically_backward): When DY == 0, make sure we get to
11934 the first character in the line after the newline.
11936 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
11938 * ccl.c: Improve and simplify overflow checking (Bug#9196).
11939 (ccl_driver): Do not generate an out-of-range pointer.
11940 (Fccl_execute_on_string): Remove unnecessary check for
11941 integer overflow, noted by Stefan Monnier in
11942 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
11943 Remove a FIXME that didn't need fixing.
11944 Simplify the newly-introduced buffer reallocation code.
11946 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
11948 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
11950 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
11952 Integer and memory overflow issues (Bug#9196).
11954 * doc.c (get_doc_string): Rework so that
11955 get_doc_string_buffer_size is the actual buffer size, rather than
11956 being 1 less than the actual buffer size; this makes xpalloc more
11959 * image.c (x_allocate_bitmap_record, cache_image):
11960 * xselect.c (Fx_register_dnd_atom):
11961 Simplify previous changes by using xpalloc.
11963 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
11964 since either will do and ptrdiff_t is convenient with xpalloc.
11966 * charset.c (charset_table_size)
11967 (struct charset_sort_data.priority): Now ptrdiff_t.
11968 (charset_compare): Don't overflow if priorities differ greatly.
11969 (Fsort_charsets): Don't assume list length fits in int.
11970 Check for size-calculation overflow when allocating sort data.
11971 (syms_of_charset): Allocate an initial charset table that is
11972 just under 64 KiB, to avoid problems with glibc malloc and mmap.
11974 * cmds.c (internal_self_insert): Check for size-calculation overflow.
11976 * composite.h (struct composition.glyph_len): Now int, not unsigned.
11977 The actual value is always <= INT_MAX, and leaving it unsigned made
11978 overflow checking harder.
11980 * dispextern.h (struct glyph_matrix.rows_allocated)
11981 (struct face_cache.size): Now ptrdiff_t, for convenience in use
11982 with xpalloc. The values are still always <= INT_MAX.
11984 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
11986 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
11987 (SAFE_NALLOCA): New macro.
11989 * region-cache.c (struct boundary.pos, find_cache_boundary)
11990 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
11991 (set_cache_region, invalidate_region_cache)
11992 (revalidate_region_cache, know_region_cache, region_cache_forward)
11993 (region_cache_backward, pp_cache):
11994 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
11995 so that ptrdiff_t * can be passed to xpalloc.
11996 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
11997 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
11998 (pp_cache): Don't assume cache_len fits in int.
11999 * region-cache.h: Adjust extern decls to match.
12001 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
12002 EMACS_INT, since either will do, for xpalloc.
12004 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
12005 (xnmalloc, xnrealloc, xpalloc): New functions.
12007 * bidi.c (bidi_shelve_header_size): New constant.
12008 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
12009 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
12011 * bidi.c (bidi_cache_shrink):
12012 * buffer.c (overlays_at, overlays_in, record_overlay_string)
12014 Don't update size of array until after memory allocation succeeds,
12015 because xmalloc/xrealloc may not return.
12016 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
12017 now that we have proper integer overflow checking.
12018 (record_overlay_string, overlay_strings): Catch overflows when
12019 calculating size of overlay_str_buf.
12021 * callproc.c (Fcall_process): Check for size overflow when
12022 calculating size of args2.
12023 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
12024 Normally we prefer signed values, but sticking with ptrdiff_t would
12025 require adding more-complicated checks.
12027 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
12028 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
12029 Redo buffer-overflow calculations to avoid integer overflow.
12030 Add a FIXME comment where memory seems to be over-allocated.
12032 * character.c (Fstring): Check for size-calculation overflow.
12034 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
12035 unnecessary integer overflow. Check for size overflow.
12036 (encode_coding_object): Don't update size until xmalloc succeeds.
12038 * composite.c (get_composition_id): Check for overflow in glyph
12039 length calculations.
12041 Integer and memory overflow fixes for display code.
12042 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
12043 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
12044 (scrolling_window): Check for overflow in size calculations.
12045 (line_draw_cost, realloc_glyph_pool, add_row_entry):
12046 Don't assume glyph table len fits in int.
12047 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
12048 (row_table_size): Now ptrdiff_t, not int.
12049 (scrolling_window): Avoid overflow in size calculations.
12050 Don't update size until allocation succeeds.
12051 * fns.c (concat): Check for overflow in size calculations.
12052 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
12053 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
12054 (NEXT_ALMOST_PRIME_LIMIT): New constant.
12056 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
12057 (get_doc_string): Check for size calculation overflow.
12058 Don't update size until allocation succeeds.
12059 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
12060 EMACS_INT, where ptrdiff_t will do.
12061 (Fsubstitute_command_keys): Check for string overflow.
12063 * editfns.c (set_time_zone_rule): Don't assume environment length
12065 (message_length): Now ptrdiff_t, not int.
12066 (Fmessage_box): Don't update size until allocation succeeds.
12067 Don't assume message length fits in int.
12068 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
12070 * emacs.c (main): Do not reallocate argv, since there is a null at
12071 the end that can be overwritten, and this way there's no need to
12072 worry about size-calculation overflow.
12073 (sort_args): Check for size-calculation overflow.
12075 * eval.c (init_eval_once, grow_specpdl): Don't update size until
12077 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
12079 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
12080 (x_set_scroll_bar_width, x_figure_window_size):
12081 Check for integer overflow.
12082 (x_set_alpha): Do not assume XINT fits in int.
12084 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
12085 This is for the members text_lines, text_cols, total_lines, total_cols,
12086 where the system imposes an 'int' limit.
12088 * fringe.c (Fdefine_fringe_bitmap):
12089 Don't update size until alloc works.
12091 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
12092 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
12094 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
12095 Check for size-calculation overflow.
12096 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
12097 do, as we prefer signed integers.
12098 (id_to_widget.max_size, id_to_widget.used)
12099 (xg_store_widget_in_map, xg_remove_widget_from_map)
12100 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
12101 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
12102 Use and return ptrdiff_t, not int.
12103 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
12104 * gtkutil.h: Change prototypes to match the above.
12106 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these

12153 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
12154 for command line length. Do not attempt to address one before the
12155 beginning of an array, as that's not portable.

12185 Check for size calculation overflow.
12186 (cache_face): Treat size calculation overflows as if they were
12187 memory exhaustion (the usual treatment), rather than aborting.
12189 * xfns.c (x_encode_text, x_set_name_internal)
12190 (Fx_change_window_property): Use ptrdiff_t, not int, to count
12191 sizes, since they can exceed INT_MAX in size. Check for size
12192 calculation overflow.

12195 (xg_select): Check for size calculation overflow.
12196 Don't update size until alloc done.
12198 * xrdb.c (get_environ_db): Don't assume path length fits in int,
12199 as sprintf is limited to int lengths.
12201 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
12202 (X_LONG_MIN): New macros.
12203 Use them to make the following changes clearer.
12204 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
12205 This change doesn't affect the value now, but it may help remind
12206 future maintainers not to raise the value too much later.
12207 (SELECTION_QUANTUM): Remove, replacing with ...
12208 (selection_quantum): ... new function, which avoids overflow.
12210 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
12211 assumption that selection length fits in 'int'.

12228 Don't store size until memory allocation succeeds.
12229 (x_get_window_property): Plug memory leak on memory exhaustion.
12230 Don't double-block input; malloc is safe here. Don't assume 2**34
12231 - 4 fits in unsigned long. Add an xassert to check
12232 XGetWindowProperty overflow. Be more careful about overflow
12233 calculations, and distinguish size from memory overflow better.
12234 (receive_incremental_selection): When tracing, don't assume
12235 unsigned int is less than INT_MAX.
12236 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory

12240 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
12241 result parameters unless successful. Rely on cons_to_unsigned
12242 to report problems with elements; the old code wasn't right anyway.
12243 (x_check_property_data): Check for int overflow; we cannot use
12244 a wider type due to X limits.

12277 * lisp.h (hash_lookup, hash_put):
12278 * minibuf.c (Ftest_completion):
12279 Use ptrdiff_t for hash table indexes, not int (which is too
12280 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
12281 32-bit --with-wide-int hosts).
12283 * charset.c (Fdefine_charset_internal): Check for integer overflow.
12284 Add a FIXME comment about memory leaks.

12292 with outlandish widths.
12293 * character.h (sanitize_tab_width): Rename from sanitize_width,
12294 now that we have two such functions. All uses changed.

12312 * xterm.c: Don't go over XClientMessageEvent limit.
12313 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
12314 (x_send_scroll_bar_event): Likewise. Check that the size does not
12315 exceed limits imposed by XClientMessageEvent, as well as the usual
12316 ptrdiff_t and size_t limits.
12318 * keyboard.c: Overflow, signedness and related fixes.
12319 (make_lispy_movement): Use same integer type in forward decl
12320 that is used in the definition.
12321 (read_key_sequence, keyremap_step):
12322 Change bufsize argument back to int, undoing my 2011-03-30 change.
12323 We prefer signed types, and int is wide enough here.
12324 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
12325 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
12326 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
12327 length, not size_t. Use ptrdiff_t for index, not int.
12328 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
12329 possibility of integer overflow.
12331 Overflow, signedness and related fixes for images.

12357 Prefer int to unsigned where either will do.
12358 (tiff_handler): New function, combining the cores of the
12359 old tiff_error_handler and tiff_warning_handler.
12360 This function is rewritten to use vsnprintf and thereby avoid
12361 stack buffer overflows. It uses only the features of vsnprintf
12362 that are common to both POSIX and native Microsoft.
12363 (tiff_error_handler, tiff_warning_handler): Use it.
12364 (tiff_load, gif_load, imagemagick_load_image):
12365 Don't assume :index value fits in 'int'.
12366 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
12367 (imagemagick_load_image): Check that crop parameters fit into
12368 the integer types that MagickCropImage accepts. Don't assume
12369 Vimagemagick_render_type has a nonnegative value. Don't assume
12370 size_t fits in 'long'.
12371 (gs_load): Use printmax_t to print the widest integers possible.
12372 Check for integer overflow when computing image height and width.

12385 (handle_single_display_spec): If the display spec is of the form
12386 `(space ...)', and specifies display in the text area, return 2
12388 (try_cursor_movement): Check for the need to scroll more
12389 accurately, and prefer exact match for point under bidi.
12390 Don't advance `row' beyond the last row of the window.

12408 buffers, return left-to-right.
12409 (set_cursor_from_row): Consider candidate row a win if its glyph
12410 represents a newline and point is on that newline. Fixes cursor
12411 positioning on the newline at EOL of R2L text within L2R
12412 paragraph, and vice versa.
12413 (try_cursor_movement): Check continued rows, in addition to
12414 continuation rows. Fixes unwarranted scroll when point enters a
12415 continued line of R2L text within an L2R paragraph, or vice versa.
12416 (cursor_row_p): Consider the case of point being equal to
12417 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving

12446 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
12447 instead of CHAR_TO_BYTE. Fixes a crash when a completion
12448 candidate is selected by the mouse, and that candidate has a
12449 composed character under the mouse.
12451 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
12452 coordinates reported by pos-visible-in-window-p for a composed
12453 character in column zero.
12455 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>

12461 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
12462 consider it a hit if to_charpos is anywhere in the range of the
12463 composed buffer positions.
12465 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
12467 * image.c (gif_load): Don't assume that each subimage has the same
12468 dimensions as the base image. Handle disposal method that is
12469 "undefined" by the gif spec (Bug#9335).
12471 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
12473 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

12483 a composition, take its buffer position from IT->cmp_it.charpos.
12484 Fixes cursor positioning at the beginning of a line that begins
12485 with a composed character.
12487 2011-08-18 Eli Zaretskii <eliz@gnu.org>
12489 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
12490 character bidirectional type, use STRONG_L instead. Fixes crashes
12491 in a buffer produced by `describe-categories'.
12493 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
12494 members before the level stack, so they would be saved and
12495 restored when copying iterator state. Fixes incorrect reordering
12496 around TABs covered by display properties.
12498 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>

12524 Fix memory allocation problems in Cygwin build (Bug#9273).
12526 * unexcw.c ( __malloc_initialized): Declare external variable.
12527 (fixup_executable): Force the dumped emacs to reinitialize malloc.
12529 * gmalloc.c [CYGWIN] (bss_sbrk_heapbase, bss_sbrk_heapinfo):

12548 * deps.mk (bidi.o): Remove biditype.h and bidimirror.h.
12550 * dispextern.h: Fix a typo in the comment to bidi_type_t.
12552 * chartab.c: Improve commentary for the uniprop_table API.
12554 * bidi.c (bidi_paragraph_init): Support zero value of
12555 bidi_ignore_explicit_marks_for_paragraph_level.
12556 (bidi_initialize): Use uniprop_table instead of including
12557 biditype.h and bidimirror.h.
12559 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
12560 coordinates of the iterator when restoring from ppos_it.
12563 2011-08-14 Kenichi Handa <handa@m17n.org>
12565 * process.c (create_process): Call setup_process_coding_systems
12566 after the pid of the process is set to -1 (Bug#8162).
12568 2011-08-14 Eli Zaretskii <eliz@gnu.org>
12570 * xdisp.c (move_it_in_display_line_to): Don't invoke
12571 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
12572 ppos_it. Fixes vertical cursor motion when line beginning is
12573 covered by an image. (Bug#9296)
12575 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
12577 * nsterm.h (ns_run_ascript): Declare.
12578 (NSAPP_DATA2_RUNASSCRIPT): Define.
12580 * nsfns.m (as_script, as_result, as_status): New static variables.
12581 (ns_run_ascript): New function.
12582 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
12583 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
12584 the event loop. Get status from as_status (Bug#7276).
12586 * nsterm.m (sendEvent): If event is NSApplicationDefined and
12587 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
12588 the event loop (Bug#7276).
12590 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
12592 * gnutls.c (QCgnutls_bootprop_priority)
12593 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
12594 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
12595 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
12596 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
12597 (QCgnutls_bootprop_verify_hostname_error)
12598 (QCgnutls_bootprop_callbacks_verify): Rename from
12599 Qgnutls_bootprop_..., all uses changed.
12601 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
12604 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
12606 * xfaces.c (Qframe_set_background_mode): Now static.
12607 * dispextern.h (Qframe_set_background_mode): Remove decl.
12609 * process.c (Fnetwork_interface_info): Declare local only if needed.
12611 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
12613 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
12614 (Fnetwork_interface_list): Allocate in increments of bytes instead
12615 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
12616 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
12618 (struct ifflag_def): notrailers is smart on OSX.
12619 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
12620 Get hardware address with getifaddrs if available.
12622 2011-08-12 Eli Zaretskii <eliz@gnu.org>
12624 * xdisp.c (iterate_out_of_display_property): xassert that
12625 IT->position is set to within IT->object's boundaries. Break from
12626 the loop as soon as EOB is reached; avoids infloops in redisplay
12627 when IT->position is set up wrongly due to some bug.
12628 Set IT->current to match the bidi iterator unconditionally.
12629 (push_display_prop): Allow GET_FROM_STRING as IT->method on
12630 entry. Force push_it to save on the stack the current
12631 buffer/string position, to be restored by pop_it. Fix flags in
12632 the iterator structure wrt the object coming from a display
12633 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
12634 properties. (Bug#9284)
12636 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
12638 * fontset.c (fontset_get_font_group): Add proper type checks.
12641 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
12643 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
12644 and LC_VERSION_MIN_MACOSX.
12645 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
12646 (dump_it) [LC_FUNCTION_STARTS]: Use it.
12648 2011-08-08 Eli Zaretskii <eliz@gnu.org>
12650 * xdisp.c (forward_to_next_line_start): Allow to use the
12651 no-display-properties-and-no-overlays under bidi display.
12652 Set disp_pos in the bidi iterator to avoid searches for display
12653 properties and overlays.
12655 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
12657 * editfns.c (Fset_time_zone_rule): Document relationship with the
12660 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
12661 the font entity extracted from the cache (Bug#8109).
12663 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
12665 * composite.c (autocmp_chars): Don't reset point. That is done by
12666 restore_point_unwind (Bug#5984).
12668 2011-08-07 Juri Linkov <juri@jurta.org>
12670 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
12671 to show the arg `TIME' instead of `TIMEVAL'.
12673 2011-08-06 Eli Zaretskii <eliz@gnu.org>
12675 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
12676 display property strides EOL and includes a newline, as in
12677 longlines-mode. (Bug#9254)
12678 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
12679 word-wrap under bidirectional display. (Bug#9224)
12681 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
12682 is non-zero, even if the data buffer is NULL. Fixes a crash in
12683 vertical-motion with longlines-mode. (Bug#9254)
12685 2011-08-05 Eli Zaretskii <eliz@gnu.org>
12687 * bidi.c <bidi_cache_total_alloc>: Now static.
12688 (bidi_initialize): Initialize bidi_cache_total_alloc.
12690 * xdisp.c (display_line): Release buffer allocated for shelved bidi
12693 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
12694 amount allocated this far in `bidi_cache_total_alloc'.
12695 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
12696 non-zero, only free the data buffer without restoring the cache
12697 contents. All callers changed.
12699 * dispextern.h (bidi_unshelve_cache): Update prototype.
12701 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
12702 (move_it_in_display_line, move_it_to)
12703 (move_it_vertically_backward, move_it_by_lines): Replace the call
12704 to xfree to an equivalent call to bidi_unshelve_cache.
12705 (move_it_in_display_line_to): Fix logic of returning
12706 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
12708 2011-08-05 Eli Zaretskii <eliz@gnu.org>
12710 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
12711 came from a string character with a `cursor' property. (Bug#9229)
12713 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
12715 * Makefile.in (LIB_PTHREAD): New variable.
12716 (LIBES): Add LIB_PTHREAD (Bug#9216).
12718 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
12719 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
12721 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
12723 * regex.c (re_iswctype): Remove some redundant boolean conversions.
12725 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
12727 * xterm.c (x_find_topmost_parent): New function.
12728 (x_set_frame_alpha): Find topmost parent window with
12729 x_find_topmost_parent and set the property there also (bug#9181).
12730 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
12732 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
12734 * callproc.c (Fcall_process): Avoid vfork clobbering
12735 the local vars buffer, coding_systems, current_dir.
12737 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
12739 * keymap.c (Fmake_composed_keymap): Move to subr.el.
12741 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
12743 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
12744 so that it is not optimized away.
12746 * xdisp.c (compute_display_string_pos): Remove unused local.
12748 2011-08-02 Eli Zaretskii <eliz@gnu.org>
12750 Fix slow cursor motion and scrolling in large buffers with
12751 selective display, like Org Mode buffers. (Bug#9218)
12753 * dispextern.h (struct bidi_it): New member disp_prop_p.
12755 * xdisp.c: Remove one-slot cache of display string positions.
12756 (compute_display_string_pos): Accept an additional argument
12757 DISP_PROP_P; callers changed. Scan at most 5K characters forward
12758 for a display string or property. If found, set DISP_PROP_P
12761 * bidi.c (bidi_fetch_char): Accept an additional argument
12762 DISP_PROP_P, and pass it to compute_display_string_pos.
12763 Only handle text covered by a display string if DISP_PROP_P is returned
12764 non-zero. All callers of bidi_fetch_char changed.
12766 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
12768 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
12770 2010-12-03 Don March <don@ohspite.net>
12772 * keymap.c (Fdefine_key): Fix non-prefix key error message when
12773 last character M-[char] is translated to ESC [char] (bug#7541).
12775 2011-08-02 Kenichi Handa <handa@m17n.org>
12777 * lisp.h (uniprop_table): Extern it.
12779 * chartab.c (uniprop_table): Make it non-static.
12781 2011-08-01 Eli Zaretskii <eliz@gnu.org>
12783 * xdisp.c (forward_to_next_line_start): Accept additional argument
12784 BIDI_IT_PREV, and store into it the state of the bidi iterator had
12786 (reseat_at_next_visible_line_start): Use the bidi iterator state
12787 returned by forward_to_next_line_start to restore the state of
12788 it->bidi_it after backing up to previous newline. (Bug#9212)
12790 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
12792 * regex.c (re_comp): Protoize.
12793 (re_exec): Fix return type.
12794 (regexec): Fix type of `ret'. (Bug#9203)
12796 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
12798 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
12799 This is needed if max-image-size is a floating-point number.
12801 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
12803 * print.c (print_object): Print empty symbol as ##.
12805 * lread.c (read1): Read ## as empty symbol.
12807 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
12809 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
12810 setting frame foreground color (Bug#9175).
12811 (x_set_background_color): Likewise.
12813 * nsmenu.m (-setText): Size tooltip dimensions precisely to
12814 contents (Bug#9176).
12815 (EmacsTooltip -init): Remove bezels and add shadows to
12818 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
12819 or scroll bar (Bug#8470).
12821 * nsfont.m (nsfont_open): Remove assignment to voffset and
12822 unnecessary vars hshink, expand, hd, full_height, min_height.
12823 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
12825 * nsterm.h (nsfont_info): Remove voffset field.
12827 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
12829 Implement strike-through and overline on NextStep (Bug#8863).
12831 * nsfont.m (nsfont_open): Use underline position provided by font,
12832 instead of hard-coded value of 2.
12833 (nsfont_draw): Call ns_draw_text_decoration instead.
12835 * nsterm.h: Add declaration for ns_draw_text_decoration.
12837 * nsterm.m (ns_draw_text_decoration): New function for drawing
12838 underline, overline, and strike-through.
12839 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
12840 ns_draw_text_decoration. Change treatment of cursor drawing to
12841 accommodate underlining, etc.
12843 2011-07-28 Eli Zaretskii <eliz@gnu.org>
12845 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
12848 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
12850 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
12851 Without this fix, if a signal arrives just after memory fills up,
12852 'malloc' might be invoked reentrantly.
12854 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
12855 In other words, assume that every image size is allowed, on non-X
12856 hosts. This assumption is probably wrong, but it lets Emacs compile.
12858 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
12860 * regex.c (re_iswctype): Convert return values to boolean.
12862 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
12864 * xdisp.c (compute_display_string_pos): Don't use cached display
12865 string position if the buffer had its restriction changed.
12868 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
12870 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
12872 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
12874 Integer signedness and overflow and related fixes. (Bug#9079)
12876 * bidi.c: Integer size and overflow fixes.
12877 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
12878 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
12879 (bidi_cache_find_level_change, bidi_cache_ensure_space)
12880 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
12881 (bidi_find_other_level_edge):
12882 Use ptrdiff_t instead of EMACS_INT where either will do.
12883 This works better on 32-bit hosts configured --with-wide-int.
12884 (bidi_cache_ensure_space): Check for size-calculation overflow.
12885 Use % rather than repeated addition, for better worst-case speed.
12886 Don't set bidi_cache_size until after xrealloc returns, because it
12888 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
12889 (bidi_cache_ensure_space): Also check that the bidi cache size
12890 does not exceed that of the largest Lisp string or buffer. See Eli
12891 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
12893 * alloc.c (__malloc_size_t): Remove.
12894 All uses replaced by size_t. See Andreas Schwab's note
12895 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
12897 * image.c: Improve checking for integer overflow.
12898 (check_image_size): Assume that f is nonnull, since
12899 it is always nonnull in practice. This is one less thing to
12900 worry about when checking for integer overflow later.
12901 (x_check_image_size): New function, which checks for integer
12902 overflow issues inside X.
12903 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
12904 This removes the need for a memory_full check.
12905 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
12906 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
12907 (xbm_read_bitmap_data): Change locals back to 'int', since
12908 their values must fit in 'int'.
12909 (xpm_load_image, png_load, tiff_load):
12910 Invoke x_create_x_image_and_pixmap earlier,
12911 to avoid much needless work if the image is too large.
12912 (tiff_load): Treat overly large images as if
12913 x_create_x_image_and_pixmap failed, not as malloc failures.
12914 (gs_load): Use x_check_image_size.
12916 * gtkutil.c: Omit integer casts.
12917 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
12918 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
12920 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
12922 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
12923 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
12924 would wrongly return t on a 64-bit host.
12926 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
12927 The plain *_OVERFLOW macros run afoul of GCC bug 49705
12928 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
12929 and therefore cause GCC to emit a bogus diagnostic in some cases.
12931 * image.c: Integer signedness and overflow and related fixes.
12932 This is not an exhaustive set of fixes, but it's time to
12933 record what I've got.
12934 (lookup_pixel_color, check_image_size): Remove redundant decls.
12935 (check_image_size): Don't assume that arbitrary EMACS_INT values
12936 fit in 'int', or that arbitrary 'double' values fit in 'int'.
12937 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
12938 (tiff_load, imagemagick_load_image):
12939 Check for overflow in size calculations.
12940 (x_create_x_image_and_pixmap): Remove unnecessary test for
12941 xmalloc returning NULL; that can't happen.
12942 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
12943 (xpm_color_bucket): Use better integer hashing function.
12944 (xpm_cache_color): Don't possibly over-allocate memory.
12945 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
12946 (gif_memory_source):
12947 Use ptrdiff_t, not int or size_t, to record sizes.
12948 (png_load): Don't assume values greater than 2**31 fit in 'int'.
12949 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
12950 either works, as we prefer signed integers.
12951 (tiff_read_from_memory, tiff_write_from_memory):
12952 Return tsize_t, not size_t, since that's what the TIFF API wants.
12953 (tiff_read_from_memory): Don't fail simply because the read would
12954 go past EOF; instead, return a short read.
12955 (tiff_load): Omit no-longer-needed casts.
12956 (Fimagemagick_types): Don't assume size fits into 'int'.
12958 Improve hashing quality when configured --with-wide-int.
12959 * fns.c (hash_string): New function, taken from sxhash_string.
12960 Do not discard information about ASCII character case; this
12961 discarding is no longer needed.
12962 (sxhash-string): Use it. Change sig to match it. Caller changed.
12963 * lisp.h: Declare it.
12964 * lread.c (hash_string): Remove, since we now use fns.c's version.
12965 The fns.c version returns a wider integer if --with-wide-int is
12966 specified, so this should help the quality of the hashing a bit.
12968 * emacs.c: Integer overflow minor fix.
12969 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
12970 Define only if GNU_LINUX.
12971 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
12973 * dispnew.c: Integer signedness and overflow fixes.
12974 Remove unnecessary forward decls, that were a maintenance hassle.
12975 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
12977 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
12978 (scrolling_window): Use ptrdiff_t, not int, for byte count.
12979 (prepare_desired_row, line_draw_cost):
12980 Use int, not unsigned, where either works.
12981 (save_current_matrix, restore_current_matrix):
12982 Use ptrdiff_t, not size_t, where either works.
12983 (init_display): Check for overflow more accurately, and without
12984 relying on undefined behavior.
12986 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
12987 Remove, replacing with the new symbols in lisp.h. All uses changed.
12988 * fileio.c (make_temp_name):
12989 * filelock.c (lock_file_1, lock_file):
12990 * xdisp.c (message_dolog):
12991 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
12992 Use pMd etc. instead.
12993 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
12994 replacing the pWIDE etc. symbols removed from editfns.c.
12996 * keyboard.h (num_input_events): Now uintmax_t.
12997 This is (very slightly) less likely to mess up due to wraparound.
13000 * buffer.c: Integer signedness fixes.
13001 (alloc_buffer_text, enlarge_buffer_text):
13002 Use ptrdiff_t rather than size_t when either will do, as we prefer
13005 * alloc.c: Integer signedness and overflow fixes.
13006 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
13007 (__malloc_size_t): Default to size_t, not to int.
13008 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
13009 (Fgarbage_collect, mark_object_loop_halt, mark_object):
13010 Prefer ptrdiff_t to size_t when either would do, as we prefer
13012 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
13013 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
13014 Now const. Initialize with values that are in range even if char
13016 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
13017 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
13018 These functions do the right thing with sizes > 2**32.
13019 (check_depth): Now ptrdiff_t, not int.
13020 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
13021 Adjust to new way of storing sizes. Check for size overflow bugs
13023 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
13024 slightly wrong anyway, as it missed one instance of
13025 XMALLOC_OVERRUN_CHECK_OVERHEAD.
13026 (refill_memory_reserve): Omit needless cast to size_t.
13027 (mark_object_loop_halt): Mark as externally visible.
13029 * xselect.c: Integer signedness and overflow fixes.
13030 (Fx_register_dnd_atom, x_handle_dnd_message):
13031 Use ptrdiff_t, not size_t, since we prefer signed.
13032 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
13033 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
13034 x_dnd_atoms_size and x_dnd_atoms_length.
13036 * doprnt.c: Prefer signed to unsigned when either works.
13038 * doprnt.c (doprnt):
13040 * xdisp.c (vmessage):
13041 Use ptrdiff_t, not size_t, when using or implementing doprnt,
13042 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
13043 prefer signed arithmetic to avoid comparison confusion.
13044 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
13045 but is a bit tricky.
13047 Assume freestanding C89 headers, string.h, stdlib.h.
13048 * data.c, doprnt.c, floatfns.c, print.c:
13049 Include float.h unconditionally.
13050 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
13051 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
13052 * regex.c: Likewise for stddef.h, string.h.
13053 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
13054 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
13055 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
13056 (STDC_HEADERS): Remove obsolete defines.
13057 * sysdep.c: Include limits.h unconditionally.
13059 Assume support for memcmp, memcpy, memmove, memset.
13060 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
13061 * regex.c (memcmp, memcpy):
13062 Remove; we assume C89 now.
13064 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
13065 (__malloc_safe_bcopy): Remove; no longer needed.
13067 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
13068 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
13069 well either way, and we prefer signed to unsigned.
13071 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
13073 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
13074 closes the connection while we're reading (bug#9182).
13076 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
13078 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
13079 are specified (Bug#9168).
13081 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
13083 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
13084 Found by GCC static checking and --with-wide-int on a 32-bit host.
13086 2011-07-25 Eli Zaretskii <eliz@gnu.org>
13088 * xdisp.c (compute_display_string_pos): Fix logic of caching
13089 previous display string position. Initialize cached_prev_pos to
13090 -1. Fixes slow-down at the beginning of a buffer.
13092 2011-07-24 Eli Zaretskii <eliz@gnu.org>
13094 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
13095 for attrs[LFACE_FONTSET_INDEX].
13097 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
13099 * xml.c (parse_region): Remove unused local
13100 that was recently introduced.
13102 2011-07-23 Eli Zaretskii <eliz@gnu.org>
13104 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
13105 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
13107 * xdisp.c (move_it_in_display_line_to): Record the best matching
13108 position for TO_CHARPOS while scanning the line, and restore it on
13109 exit if none of the characters scanned was an exact match.
13110 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
13111 when exact match is impossible due to invisible text, and the
13112 lines are truncated.
13114 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
13116 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
13119 2011-07-22 Eli Zaretskii <eliz@gnu.org>
13121 Fix a significant slow-down of cursor motion with C-n, C-p,
13122 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
13123 auto-repeat under bidi redisplay in fontified buffers.
13124 * xdisp.c (compute_stop_pos_backwards): New function.
13125 (next_element_from_buffer): Call compute_stop_pos_backwards to
13126 find a suitable prev_stop when we find ourselves before
13128 (reseat): Don't look for prev_stop, as that could mean a very long
13130 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
13131 <cached_disp_overlay_modiff>: Cache for last found display string
13133 (compute_display_string_pos): Return the cached position if asked
13134 about the same buffer in the same area of character positions, and
13135 the buffer wasn't changed since the time the display string
13136 position was cached.
13138 2011-07-22 Eli Zaretskii <eliz@gnu.org>
13140 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
13141 is an integer, which is important for empty lines. (Bug#9149)
13143 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
13145 * frame.c (Fmodify_frame_parameters): In tty case, update the
13146 default face if necessary (Bug#4238).
13148 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
13150 * editfns.c (Fstring_to_char): No need to explain what a character
13151 is in the docstring (Bug#6576).
13153 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
13155 * xml.c (parse_region): Make sure we always return a tree.
13157 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
13159 * xml.c (parse_region): If a document contains only comments,
13162 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
13164 * xml.c (make_dom): Return comments, too.
13166 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
13169 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
13170 and the surrounding thread.
13171 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
13172 rather than fgets, and retry after EINTR. Otherwise, 'emacs
13173 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
13175 * s/openbsd.h (BROKEN_SIGIO): Define.
13176 * unexelf.c (unexec) [__OpenBSD__]:
13177 Don't update the .mdebug section of the Alpha COFF symbol table.
13179 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
13181 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
13184 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
13186 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
13187 This fixes some race conditions on the permissions of any newly
13190 * alloc.c (valid_pointer_p): Use pipe, not open.
13191 This fixes some permissions issues when debugging.
13193 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
13194 If fchown fails to set both uid and gid, try to set just gid,
13195 as that is sometimes allowed. Adjust the file's mode to eliminate
13196 setuid or setgid bits that are inappropriate if fchown fails.
13198 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
13200 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
13201 to compare Lisp_Objects.
13202 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
13203 global_gnutls_log_level, don't mistake it for a Lisp_Object.
13204 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
13206 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
13208 * lread.c (read_integer): Unread even EOF character.
13209 (read1): Likewise. Properly record start position of symbol.
13211 * lread.c (read1): Read `#:' as empty uninterned symbol if no
13212 symbol character follows.
13214 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
13216 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
13217 This works around a problem with the previous change to Fcopy_file.
13218 Recent glibc declares fchown with __attribute__((warn_unused_result)),
13219 and without this change, GCC might complain about discarding
13220 fchown's return value.
13222 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
13224 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
13226 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
13228 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
13230 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
13232 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
13233 it's used from the C level.
13235 * process.c: Use the same condition for POLL_FOR_INPUT in both
13236 keyboard.c and process.c (bug#1858).
13238 2011-07-09 Lawrence Mitchell <wence@gmx.li>
13240 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
13241 (Fgnutls_boot): Use it.
13243 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
13245 * doc.c (Fsubstitute_command_keys): Revert last change.
13247 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
13249 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
13250 quotes the next character, and doesn't affect other longer
13251 sequences (bug#8935).
13253 * lread.c (syms_of_lread): Clarify that is isn't only
13254 `eval-buffer' and `eval-defun' that's affected by
13255 `lexical-binding' (bug#8460).
13257 2011-07-15 Eli Zaretskii <eliz@gnu.org>
13259 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
13260 bidi redisplay when a line includes both an image and is truncated.
13262 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
13264 Fix minor problems found by static checking.
13265 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
13266 (elsz): Now a signed constant, not a size_t var. We prefer signed
13267 types to unsigned, to avoid integer comparison confusion. Without
13268 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
13269 "cannot optimize loop, the loop counter may overflow", a symptom
13271 * indent.c (Fvertical_motion): Mark locals as initialized.
13272 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
13274 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
13276 * search.c (Fre_search_backward): Mention `case-fold-search' in
13277 all the re_search_* functions (bug#8138).
13279 * keyboard.c (Fopen_dribble_file): Document when the file is

13290 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
13291 (reseat_to_string): Initialize bidi_it->string.s and
13292 bidi_it->string.schars.
13293 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
13294 NULL (avoids a crash in bidi_paragraph_init).
13295 Initialize itb.string.lstring.
13296 (init_iterator): Call bidi_init_it only of a valid
13297 buffer position was specified. Initialize paragraph_embedding to
13299 (reseat_to_string): Initialize the bidi iterator.
13300 (display_string): If we need to ignore text properties of
13301 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
13302 original value of -1 will not work with bidi.)
13303 (compute_display_string_pos): First arg is now struct
13304 `text_pos *'; all callers changed. Support display properties on
13306 (compute_display_string_end): Support display properties on Lisp
13308 (init_iterator, reseat_1, reseat_to_string): Initialize the
13309 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
13310 when iterating on a string not from display properties).
13311 (compute_display_string_pos, compute_display_string_end):
13312 Fix calculation of the object to scan. Fixes an error when using
13314 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
13315 base_level_stop; instead, set base_level_stop to BEGV.
13316 Fixes crashes in vertical-motion.
13317 (next_element_from_buffer): Improve commentary for when
13318 the iterator is before prev_stop.
13319 (init_iterator): Initialize bidi_p from the default value of
13320 bidi-display-reordering, not from buffer-local value. Use the
13321 buffer-local value only if initializing for buffer iteration.
13322 (handle_invisible_prop): Support invisible properties on strings
13323 that are being bidi-reordered.
13324 (set_iterator_to_next): Support bidi reordering of C strings and
13326 (next_element_from_string): Support bidi reordering of Lisp
13328 (handle_stop_backwards): Support Lisp strings as well.
13329 (display_string): Support display of R2L glyph rows.
13330 Use IT_STRING_CHARPOS when displaying from a Lisp string.
13331 (init_iterator): Don't initialize it->bidi_p for strings
13333 (reseat_to_string): Initialize it->bidi_p for strings here.
13334 (next_element_from_string, next_element_from_c_string)
13335 (next_element_from_buffer): Add xassert's for correspondence
13336 between IT's object being iterated and it->bidi_it.string
13338 (face_before_or_after_it_pos): Support bidi iteration.
13339 (next_element_from_c_string): Handle the case of the first string
13340 character that is not the first one in the visual order.
13341 (get_visually_first_element): New function, refactored from common
13342 parts of next_element_from_buffer, next_element_from_string, and
13343 next_element_from_c_string.
13344 (tool_bar_lines_needed, redisplay_tool_bar)
13345 (display_menu_bar): Force left-to-right direction. Add a FIXME
13346 comment for making that be controlled by a user option.
13347 (push_it, pop_it): Save and restore the state of the
13348 bidi iterator. Save and restore the bidi_p flag.
13349 (pop_it): Iterate out of display property for string iteration as
13351 (iterate_out_of_display_property): Support iteration over strings.
13352 (handle_single_display_spec): Set up it->bidi_it for iteration
13353 over a display string, and call bidi_init_it.
13354 (handle_single_display_spec, next_overlay_string)
13355 (get_overlay_strings_1, push_display_prop): Set up the bidi
13356 iterator for displaying display or overlay strings.
13357 (forward_to_next_line_start): Don't use the shortcut if
13359 (back_to_previous_visible_line_start): If handle_display_prop
13360 pushed the iterator stack, restore the internal state of the bidi
13361 iterator by calling bidi_pop_it same number of times.
13362 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
13363 and we are bidi-iterating, don't decrement the iterator position;
13364 instead, set the first_elt flag in the bidi iterator, to produce
13366 (reseat_1): Remove redundant setting of string_from_display_prop_p.
13367 (push_display_prop): xassert that we are iterating a buffer.
13368 (push_it, pop_it): Save and restore paragraph_embedding member.
13369 (handle_single_display_spec, next_overlay_string)
13370 (get_overlay_strings_1, reseat_1, reseat_to_string)
13371 (push_display_prop): Set up the `unibyte' member of bidi_it.string
13372 correctly. Don't assume unibyte strings are not bidi-reordered.
13373 (compute_display_string_pos)
13374 (compute_display_string_end): Fix handling the case of C string.
13375 (push_it, pop_it): Save and restore from_disp_prop_p.
13376 (handle_single_display_spec, push_display_prop): Set the
13377 from_disp_prop_p flag.
13378 (get_overlay_strings_1): Reset the from_disp_prop_p flag.
13379 (pop_it): Call iterate_out_of_display_property only if we are
13380 popping after iteration over a string that came from a display
13381 property. Fix a typo in popping stretch info. Add an assertion
13382 for verifying that the iterator position is in sync with the bidi
13384 (handle_single_display_spec, get_overlay_strings_1)
13385 (push_display_prop): Fix initialization of paragraph direction for
13386 string when that of the parent object is not yet determined.
13387 (reseat_1): Call bidi_init_it to resync the bidi
13388 iterator with IT's position. (Bug#7616)
13389 (find_row_edges): If ROW->start.pos gives position
13390 smaller than min_pos, use it as ROW->minpos. (Bug#7616)
13391 (handle_stop, back_to_previous_visible_line_start, reseat_1):
13392 Reset the from_disp_prop_p flag.
13393 (SAVE_IT, RESTORE_IT): New macros.
13394 (pos_visible_p, face_before_or_after_it_pos)
13395 (back_to_previous_visible_line_start)
13396 (move_it_in_display_line_to, move_it_in_display_line)
13397 (move_it_to, move_it_vertically_backward, move_it_by_lines)
13398 (try_scrolling, redisplay_window, display_line): Use them when
13399 saving a temporary copy of the iterator and restoring it back.
13400 (back_to_previous_visible_line_start, reseat_1)
13401 (init_iterator): Empty the bidi cache "stack".
13402 (move_it_in_display_line_to): If iterator ended up at
13403 EOL, but we never saw any buffer positions smaller than
13404 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
13405 motion in bidi-reordered lines.
13406 (move_it_in_display_line_to): Record prev_method and prev_pos
13407 immediately before the call to set_iterator_to_next. Fixes cursor
13408 motion in bidi-reordered lines with stretch glyphs and strings
13409 displayed in margins. (Bug#8133) (Bug#8867)
13410 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
13412 (pos_visible_p): Support positions in bidi-reordered lines.
13413 Save and restore bidi cache.
13415 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.
13416 (bidi_paragraph_info): Delete unused struct.
13417 (bidi_cache_idx, bidi_cache_last_idx): Declare EMACS_INT.
13418 (bidi_cache_start): New variable.
13419 (bidi_cache_reset): Reset bidi_cache_idx to bidi_cache_start, not
13421 (bidi_cache_fetch_state, bidi_cache_search)
13422 (bidi_cache_find_level_change, bidi_cache_iterator_state)
13423 (bidi_cache_find, bidi_peek_at_next_level)

13427 (bidi_fetch_char): Accept new argument STRING; all callers
13428 changed. Support iteration over a string. Support strings with
13429 display properties. Support unibyte strings. Fix the type of

13528 * buffer.c (Fget_buffer_create): Initialize inhibit_shrinking.
13529 The old code sometimes used this field without initializing it.
13531 * alloc.c (gc_sweep): Don't read past end of array.
13532 In theory, the old code could also have corrupted Emacs internals,

13837 Random fixes. E.g., (random) never returned negative values.
13838 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
13839 subseconds part to the entropy, as that's a bit more random.
13840 Prefer signed to unsigned, since the signedness doesn't matter and
13841 in general we prefer signed. When given a limit, use a
13842 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
13843 latter isn't right if USE_2_TAGS_FOR_INTS.
13844 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
13845 not 0..VALMASK. Don't discard "excess" bits that random () returns.

13857 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
13858 This is more efficient than Ffile_directory_p and avoids a minor race.
13860 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
13862 * buffer.c (Foverlay_put): Say what the return value is
13865 * fileio.c (barf_or_query_if_file_exists): Check first if the file
13866 is a directory before asking whether to use the file name

13990 * eval.c (struct backtrace): Simplify and port the data structure.
13991 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
13992 signed bit field, as this assumption is not portable and it makes
13993 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
13994 "char debug_on_exit : 1" as this is not portable either; instead,
13995 use the portable "unsigned int debug_on_exit : 1". Remove unused
13996 member evalargs. Remove obsolete comments about cc bombing out.

14186 (read1): Check for integer overflow in radices, and in
14187 read-circle numbers.
14188 (read_escape): Avoid int overflow.
14189 (Fload, openp, read_buffer_size, read1)
14190 (substitute_object_recurse, read_vector, read_list, map_obarray):

14214 The following patches are for when GLYPH_DEBUG && !XASSERT.

14231 on undefined behavior with wrong number of arguments.
14232 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
14233 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
14234 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
14235 since we're not interested in debugging glyphs with old libraries.
14236 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
14237 GCC 4.6.0's static checking.
14239 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>

14278 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
14279 (x_session_initialize): Do not assume string length fits in int.
14281 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
14282 This is unlikely, but can occur if DPI is outlandish.
14284 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):

14313 * gtkutil.c (style_changed_cb): Avoid need for strlen.
14315 * font.c: Don't assume string length fits in int.
14316 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
14317 Use ptrdiff_t, not int.
14318 (font_intern_prop): Don't assume string length fits in int.
14319 Don't assume integer property fits in fixnum.
14320 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
14322 * filelock.c: Fix some buffer overrun and integer overflow issues.
14323 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
14324 Reformulate so as not to need the command string.
14325 Invoke gzip -cd rather than gunzip, as it's more portable.
14326 (lock_info_type, lock_file_1, lock_file):
14327 Don't assume pid_t and time_t fit in unsigned long.
14328 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
14329 (current_lock_owner): Prefer signed type for sizes.
14330 Use memcpy, not strncpy, where memcpy is what is really wanted.
14331 Don't assume (via atoi) that time_t and pid_t fit in int.
14332 Check for time_t and/or pid_t out of range, e.g., via a network share.
14333 Don't alloca where an auto var works fine.
14335 * fileio.c: Fix some integer overflow issues.
14336 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
14337 Don't assume string length fits in int.
14338 (directory_file_name): Don't assume string length fits in long.
14339 (make_temp_name): Don't assume pid fits in int, or that its print
14340 length is less than 20.
14342 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
14344 * coding.c (make_subsidiaries): Don't assume string length fits in int.
14346 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
14348 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
14349 We prefer signed integers, even for size calculations.
14351 * emacs.c: Don't assume string length fits in 'int'.
14352 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
14353 (main): Don't invoke strlen when not needed.
14355 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
14356 (XD_DEBUG_MESSAGE): Don't waste a byte.
14358 * callproc.c (getenv_internal_1, getenv_internal)
14359 (Fgetenv_internal):
14360 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
14362 * lread.c (invalid_syntax): Omit length argument.
14363 All uses changed. This doesn't fix a bug, but it simplifies the
14364 code away from its former Hollerith-constant appearance, and it's
14365 one less 'int' to worry about when looking at integer-overflow issues.
14366 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
14368 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
14369 This didn't break anything, but it didn't help either.
14370 It's confusing to put a bogus integer in a place where the actual
14371 value does not matter.
14372 (LIST_END_P): Remove unused macro and its bogus comment.
14373 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
14375 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
14376 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
14378 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
14379 We prefer signed types, and the value cannot exceed the EMACS_INT
14380 range anyway (because otherwise the length would not be representable).
14381 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
14382 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
14383 This avoids a GCC warning when WIDE_EMACS_INT.
14385 * indent.c (sane_tab_width): New function.
14386 (current_column, scan_for_column, Findent_to, position_indentation)
14387 (compute_motion): Use it. This is just for clarity.
14388 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
14390 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
14392 * lisp.h (lint_assume): New macro.
14393 * composite.c (composition_gstring_put_cache):
14394 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
14396 * editfns.c, insdel.c:
14397 Omit unnecessary forward decls, to simplify future changes.
14399 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
14401 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
14403 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
14404 Use much-faster test for byte-length change.
14405 Don't assume string byte-length fits in 'int'.
14406 Check that character arg fits in 'int'.
14407 (mapcar1): Declare byte as byte, for clarity.
14409 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
14411 * fns.c (concat): Catch string overflow earlier.
14412 Do not rely on integer wraparound.
14414 * dispextern.h (struct it.overlay_strings_charpos)
14415 (struct it.selective): Now EMACS_INT, not int.
14416 * xdisp.c (forward_to_next_line_start)
14417 (back_to_previous_visible_line_start)
14418 (reseat_at_next_visible_line_start, next_element_from_buffer):
14419 Don't arbitrarily truncate the value of 'selective' to int.
14421 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
14423 * composite.c: Don't truncate sizes to 'int'.
14424 (composition_gstring_p, composition_reseat_it)
14425 (composition_adjust_point): Use EMACS_INT, not int.
14426 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
14427 not EMACS_UINT, for indexes.
14429 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
14431 * buffer.c: Include <verify.h>.
14432 (struct sortvec.priority, struct sortstr.priority):
14433 Now EMACS_INT, not int.
14434 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
14435 (struct sortstr.size, record_overlay_string)
14436 (struct sortstrlist.size, struct sortlist.used):
14437 Don't truncate size to int.
14438 (record_overlay_string): Check for size-calculation overflow.
14439 (init_buffer_once): Check at compile-time, not run-time.
14441 2011-06-22 Jim Meyering <meyering@redhat.com>
14443 Don't leak an XBM-image-sized buffer
14444 * image.c (xbm_load): Free the image buffer after using it.
14446 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
14449 * composite.c (find_automatic_composition): Omit needless 'return 0;'
14450 that Sun C diagnosed.
14451 * fns.c (secure_hash): Fix pointer signedness issue.
14452 * intervals.c (static_offset_intervals): New function.
14453 (offset_intervals): Use it.
14455 2011-06-21 Leo Liu <sdl.web@gmail.com>
14458 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
14461 * fns.c (secure_hash): Rename from crypto_hash_function and change
14462 the first arg to accept symbols.
14463 (Fsecure_hash): New primitive.
14464 (syms_of_fns): New symbols.
14466 2011-06-20 Deniz Dogan <deniz@dogan.se>
14468 * process.c (Fset_process_buffer): Clarify return value in
14471 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
14473 * dispnew.c (add_window_display_history): Use BVAR.
14475 * xdisp.c (debug_method_add): Use BVAR.
14476 (check_window_end, dump_glyph_matrix, dump_glyph)
14477 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
14479 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
14482 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
14483 check till after the cache is created in init_frame_faces.
14485 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
14487 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
14489 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
14491 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
14492 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
14493 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
14495 Improve buffer-overflow checking (Bug#8873).
14496 * fileio.c (Finsert_file_contents):
14497 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
14498 Remove the old (too-loose) buffer overflow checks.
14499 They weren't needed, since make_gap checks for buffer overflow.
14500 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
14501 The old code merely checked for Emacs fixnum overflow, and relied
14502 on undefined (wraparound) behavior. The new code avoids undefined
14503 behavior, and also checks for ptrdiff_t and/or size_t overflow.
14505 * editfns.c (Finsert_char): Don't dump core with very negative counts.
14506 Tune. Don't use wider integers than needed. Don't use alloca.
14507 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
14509 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
14511 * insdel.c, lisp.h (buffer_overflow): New function.
14512 (insert_from_buffer_1, replace_range, replace_range_2):
14513 * insdel.c (make_gap_larger):
14514 * editfns.c (Finsert_char):
14515 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
14517 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
14519 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
14521 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
14523 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
14524 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
14526 * fileio.c: Don't assume EMACS_INT fits in off_t.
14527 (emacs_lseek): New static function.
14528 (Finsert_file_contents, Fwrite_region): Use it.
14529 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
14531 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
14533 * fns.c: Don't overflow int when computing a list length.
14534 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
14535 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
14536 truncation on 64-bit hosts. Check for QUIT every
14537 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
14538 faster and is responsive enough.
14539 (Flength): Report an error instead of overflowing an integer.
14540 (Fsafe_length): Return a float if the value is not representable
14541 as a fixnum. This shouldn't happen except in contrived situations.
14542 (Fnthcdr, Fsort): Don't assume list length fits in int.
14543 (Fcopy_sequence): Don't assume vector length fits in int.
14545 * alloc.c: Check that resized vectors' lengths fit in fixnums.
14546 (header_size, word_size): New constants.
14547 (allocate_vectorlike): Don't check size overflow here.
14548 (allocate_vector): Check it here instead, since this is the only
14549 caller of allocate_vectorlike that could cause overflow.
14550 Check that the new vector's length is representable as a fixnum.
14552 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
14553 The previous code was bogus. For example, next_almost_prime (32)
14554 returned 39, which is undesirable as it is a multiple of 3; and
14555 next_almost_prime (24) returned 25, which is a multiple of 5 so
14556 why was the code bothering to check for multiples of 7?
14558 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
14560 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
14562 Variadic C functions now count arguments with ptrdiff_t.
14563 This partly undoes my 2011-03-30 change, which replaced int with size_t.
14564 Back then I didn't know that the Emacs coding style prefers signed int.
14565 Also, in the meantime I found a few more instances where arguments
14566 were being counted with int, which may truncate counts on 64-bit
14567 machines, or EMACS_INT, which may be unnecessarily wide.
14568 * lisp.h (struct Lisp_Subr.function.aMANY)
14569 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
14570 Arg counts are now ptrdiff_t, not size_t.
14571 All variadic functions and their callers changed accordingly.
14572 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
14573 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
14574 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
14575 * callint.c (Fcall_interactively): Check arg count for overflow,
14576 to avoid potential buffer overrun. Use signed char, not 'int',
14577 for 'varies' array, so that we needn't bother to check its size
14578 calculation for overflow.
14579 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
14580 * eval.c (apply_lambda):
14581 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
14582 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
14583 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
14585 * callint.c (Fcall_interactively): Don't use index var as event count.
14587 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
14588 * mem-limits.h (SIZE): Remove; no longer used.
14590 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
14592 Remove unnecessary casts.
14593 * xterm.c (x_term_init):
14594 * xfns.c (x_set_border_pixel):
14595 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
14596 These aren't needed now that we assume ANSI C.
14598 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
14599 It's more likely to cause problems (due to unsigned overflow)
14602 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
14604 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
14606 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
14608 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
14610 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
14612 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
14614 GLYPH_CODE_FACE returns EMACS_INT, not int.
14615 * dispextern.h (merge_faces):
14616 * xfaces.c (merge_faces):
14617 * xdisp.c (get_next_display_element, next_element_from_display_vector):
14618 Don't assume EMACS_INT fits in int.
14620 * character.h (CHAR_VALID_P): Remove unused parameter.
14621 * fontset.c, lisp.h, xdisp.c: All uses changed.
14623 * editfns.c (Ftranslate_region_internal): Omit redundant test.
14625 * fns.c (concat): Minor tuning based on overflow analysis.
14626 This doesn't fix any bugs. Use int to hold character, instead
14627 of constantly refetching from Emacs object. Use XFASTINT, not
14628 XINT, for value known to be a character. Don't bother comparing
14629 a single byte to 0400, as it's always less.
14631 * floatfns.c (Fexpt):
14632 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
14634 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
14637 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
14639 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
14640 Without this fix, on a 64-bit host (aset S 0 4294967386) would
14641 incorrectly succeed when S was a string, because 4294967386 was
14642 truncated before it was used.
14644 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
14645 Otherwise, an out-of-range integer could cause undefined behavior
14648 * composite.c: Use int, not EMACS_INT, for characters.
14649 (fill_gstring_body, composition_compute_stop_pos): Use int, not
14650 EMACS_INT, for values that are known to be in character range.
14651 This doesn't fix any bugs but is the usual style inside Emacs and
14652 may generate better code on 32-bit machines.
14654 Make sure a 64-bit char is never passed to ENCODE_CHAR.
14655 This is for reasons similar to the recent CHAR_STRING fix.
14656 * charset.c (Fencode_char): Check that character arg is actually
14657 a character. Pass an int to ENCODE_CHAR.
14658 * charset.h (ENCODE_CHAR): Verify that the character argument is no
14659 wider than 'int', as a compile-time check to prevent future regressions
14662 * character.c (char_string): Remove unnecessary casts.
14664 Make sure a 64-bit char is never passed to CHAR_STRING.
14665 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
14666 by silently ignoring the top 32 bits, allowing some values
14667 that were far too large to be valid characters.
14668 * character.h: Include <verify.h>.
14669 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
14670 arguments are no wider than unsigned, as a compile-time check
14671 to prevent future regressions in this area.
14673 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
14674 (Fsubst_char_in_region):
14676 * xdisp.c (decode_mode_spec_coding):
14677 Adjust to CHAR_STRING's new requirement.
14678 * editfns.c (Finsert_char, Fsubst_char_in_region):
14679 * fns.c (concat): Check that character args are actually
14680 characters. Without this test, these functions did the wrong
14681 thing with wildly out-of-range values on 64-bit hosts.
14683 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
14684 These casts should not be needed on 32-bit hosts, either.
14685 * keyboard.c (read_char):
14686 * lread.c (Fload): Remove casts to unsigned.
14688 * lisp.h (UNSIGNED_CMP): New macro.
14689 This fixes comparison bugs on 64-bit hosts.
14690 (ASCII_CHAR_P): Use it.
14691 * casefiddle.c (casify_object):
14692 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
14693 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
14694 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
14695 * dispextern.h (FACE_FROM_ID):
14696 * keyboard.c (read_char): Use UNSIGNED_CMP.
14698 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
14699 not to EMACS_INT, to avoid GCC warning.
14701 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
14703 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
14704 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
14705 isn't needed on 32-bit machines.
14707 * buffer.c (Fgenerate_new_buffer_name):
14708 Use EMACS_INT for count, not int.
14709 (advance_to_char_boundary): Return EMACS_INT, not int.
14711 * data.c (Qcompiled_function): Now static.
14713 * window.c (window_body_lines): Now static.
14715 * image.c (gif_load): Rename local to avoid shadowing.
14717 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
14718 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
14719 * alloc.c (make_save_value): Integer argument is now of type
14720 ptrdiff_t, not int.
14721 (mark_object): Use ptrdiff_t, not int.
14722 * lisp.h (pD): New macro.
14723 * print.c (print_object): Use it.
14725 * alloc.c: Use EMACS_INT, not int, to count objects.
14726 (total_conses, total_markers, total_symbols, total_vector_size)
14727 (total_free_conses, total_free_markers, total_free_symbols)
14728 (total_free_floats, total_floats, total_free_intervals)
14729 (total_intervals, total_strings, total_free_strings):
14730 Now EMACS_INT, not int. All uses changed.
14731 (Fgarbage_collect): Compute overall total using a double, so that
14732 integer overflow is less likely to be a problem. Check for overflow
14733 when converting back to an integer.
14734 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
14735 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
14736 These were 'int' variables that could overflow on 64-bit hosts;
14737 they were never used, so remove them instead of repairing them.
14738 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
14739 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
14740 Previously, this ceilinged at INT_MAX, but that doesn't work on
14742 (allocate_pseudovector): Don't use EMACS_INT when int would do.
14744 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
14745 (allocate_vectorlike): Check for ptrdiff_t overflow.
14746 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
14747 when a (possibly-narrower) signed value would do just as well.
14748 We prefer using signed arithmetic, to avoid comparison confusion.
14750 * alloc.c: Catch some string size overflows that we were missing.
14751 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
14752 for convenience in STRING_BYTES_MAX.

15193 malloc) and ptrdiff_t (for sanity and safety).
15195 * fileio.c (Fverify_visited_file_modtime): Avoid time overflow
15196 if b->modtime has its maximal value.
15198 * dired.c (Ffile_attributes): Don't assume EMACS_INT has >32 bits.
15200 Don't assume time_t can fit into int.
15201 * buffer.h (struct buffer.modtime): Now time_t, not int.
15202 * fileio.c (Fvisited_file_modtime): No need for time_t cast now.
15203 * undo.c (Fprimitive_undo): Use time_t, not int, for time_t value.
15205 Minor fixes for signed vs unsigned integers.
15206 * character.h (MAYBE_UNIFY_CHAR):
15207 * charset.c (maybe_unify_char):
15208 * keyboard.c (read_char, reorder_modifiers):
15209 XINT -> XFASTINT, since the integer must be nonnegative.
15210 * ftfont.c (ftfont_spec_pattern):
15211 * keymap.c (access_keymap, silly_event_symbol_error):
15212 XUINT -> XFASTINT, since the integer must be nonnegative.
15213 (Fsingle_key_description, preferred_sequence_p): XUINT -> XINT,
15214 since it makes no difference and we prefer signed.
15215 * keyboard.c (record_char): Use XUINT when all the neighbors do.
15216 (access_keymap): NATNUMP -> INTEGERP, since the integer must be

15262 (Fselected_window, select_window, Fselect_window): Move up in
15263 code. Minor doc-string fixes.
15265 2011-06-06 Paul Eggert <eggert@cs.ucla.edu>
15267 * alloc.c (memory_full) [SYSTEM_MALLOC]: Port to MacOS (Bug#8800).
15268 Do not assume that spare memory exists; that assumption is valid
15269 only if SYSTEM_MALLOC.
15270 (LARGE_REQUEST): New macro, so that the issue of large requests
15271 is separated from the issue of spare memory.
15273 2011-06-05 Andreas Schwab <schwab@linux-m68k.org>
15275 * editfns.c (Fformat): Correctly handle zero flag with hexadecimal

15301 New error handlers.
15302 (x_clipboard_manager_save_frame, x_clipboard_manager_save_all):
15303 Obey Vx_select_enable_clipboard_manager. Catch errors in
15304 x_clipboard_manager_save (Bug#8779).
15305 (Vx_select_enable_clipboard_manager): New variable.
15306 (x_get_foreign_selection): Reduce scope of x_catch_errors (Bug#8790).
15308 2011-06-04 Dan Nicolaescu <dann@ics.uci.edu>
15310 * emacs.c (main): Warn when starting a GTK emacs in daemon mode.
15312 2011-06-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15314 * fringe.c (update_window_fringes): Don't update overlay arrow bitmap
15315 in the current matrix if keep_current_p is non-zero.

15326 (bidi_fetch_char, bidi_fetch_char_advance): New functions.
15327 (bidi_cache_search, bidi_cache_iterator_state)
15328 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
15329 (bidi_level_of_next_char, bidi_move_to_visually_next):
15330 Support character positions inside a run of characters covered by a
15332 (bidi_paragraph_init, bidi_resolve_explicit_1)
15333 (bidi_level_of_next_char): Call bidi_fetch_char and
15334 bidi_fetch_char_advance instead of FETCH_CHAR and

15337 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
15339 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
15340 instead of using explicit *_CHAR codes.
15341 (bidi_resolve_explicit, bidi_resolve_weak):
15342 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
15343 bidirectional text is supported only in multibyte buffers.
15344 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
15345 it to initialize the frame_window_p member of struct bidi_it.

15349 bidi_it->nchars is non-positive.
15350 (bidi_level_of_next_char): Don't try to lookup the cache for the
15351 next/previous character if nothing is cached there yet, or if we
15352 were just reseat()'ed to a new position.
15354 * xdisp.c (set_cursor_from_row): Set start and stop points
15355 according to the row's direction when priming the loop that looks
15356 for the glyph on which to display cursor.
15357 (single_display_spec_intangible_p): Function deleted.
15358 (display_prop_intangible_p): Reimplement to call
15359 handle_display_spec instead of single_display_spec_intangible_p.
15360 Accept 3 additional arguments needed by handle_display_spec.
15361 This fixes incorrect cursor motion across display property with complex
15362 values: lists, `(when COND...)' forms, etc.
15363 (single_display_spec_string_p): Support property values that are
15364 lists with the argument STRING its top-level element.
15365 (display_prop_string_p): Fix the condition for processing a
15366 property that is a list to be consistent with handle_display_spec.

15368 last portion of handle_display_prop.
15369 (compute_display_string_pos): Accept additional argument
15370 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
15371 value of a `display' property is a "replacing spec".
15372 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
15373 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
15374 the display property, but just return a value indicating whether
15375 the display property will replace the characters it covers.
15376 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
15377 frame_window_p members of struct bidi_it.
15378 (compute_display_string_pos, compute_display_string_end):
15380 (push_it): Accept second argument POSITION, where pop_it should
15381 jump to continue iteration.
15382 (reseat_1): Initialize bidi_it.disp_pos.
15384 * keyboard.c (adjust_point_for_property): Adjust the call to
15385 display_prop_intangible_p to its new signature.
15387 * dispextern.h (struct bidi_it): New member frame_window_p.
15388 (bidi_init_it): Update prototypes.
15389 (display_prop_intangible_p): Update prototype.
15390 (compute_display_string_pos, compute_display_string_end):

15395 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
15397 Malloc failure behavior now depends on size of allocation.
15398 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
15399 * lisp.h: Change signatures accordingly.
15400 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
15401 All callers changed. (Bug#8762)
15403 * gnutls.c: Use Emacs's memory allocators.
15404 Without this change, the gnutls library would invoke malloc etc.
15405 directly, which causes problems on non-SYNC_INPUT hosts, and which
15406 runs afoul of improving memory_full behavior. (Bug#8761)
15407 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
15408 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
15409 xfree instead of the default malloc, realloc, free.
15410 (Fgnutls_boot): No need to check for memory allocation failure,
15411 since xmalloc does that for us.
15413 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
15414 * category.c (hash_get_category_set):
15415 * ccl.c (ccl_driver):

15427 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
15428 (Fsxhash, Fgethash, Fputhash, Fmaphash):
15429 * image.c (make_image, search_image_cache, lookup_image)
15430 (xpm_put_color_table_h):
15431 * lisp.h (struct Lisp_Hash_Table):
15432 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
15433 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
15434 for hashes and hash indexes, instead of 'unsigned' and 'int'.
15435 * alloc.c (allocate_vectorlike):
15436 Check for overflow in vector size calculations.
15437 * ccl.c (ccl_driver):
15438 Check for overflow when converting EMACS_INT to int.
15439 * fns.c, image.c: Remove unnecessary static decls that would otherwise
15440 need to be updated by these changes.
15441 * fns.c (make_hash_table, maybe_resize_hash_table):
15442 Check for integer overflow with large hash tables.
15443 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
15444 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
15445 (SXHASH_REDUCE): New macro.
15446 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
15447 Use it instead of discarding useful hash info with large hash values.
15448 (sxhash_float): New function.
15449 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
15450 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
15451 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
15452 Rewrite to use FIXNUM_BITS, as this simplifies things.
15453 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
15454 Adjust signatures to match updated version of code.
15455 (consing_since_gc): Now EMACS_INT, since a single hash table can
15456 use more than INT_MAX bytes.
15458 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
15460 Make it possible to build with GCC-4.6+ -O2 -flto.
15462 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
15464 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
15466 * minibuf.c (get_minibuffer, read_minibuf_unwind):
15467 Call minibuffer-inactive-mode.
15469 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
15471 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
15472 Update dependencies.
15474 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
15476 * data.c (init_data): Remove code for UTS, this system is not
15479 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
15481 Don't force ./temacs to start in terminal mode.
15483 * frame.c (make_initial_frame): Initialize faces in all cases, not
15484 only when CANNOT_DUMP is defined.
15485 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
15487 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
15489 * dispnew.c (add_window_display_history): Use const for the string
15490 pointer. Remove declaration, not needed.
15492 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
15494 Use 'inline', not 'INLINE'.
15495 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
15496 * alloc.c, fontset.c (INLINE): Remove.
15497 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
15498 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
15499 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
15500 * gmalloc.c (register_heapinfo): Use inline unconditionally.
15501 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
15503 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
15505 Make it possible to run ./temacs.
15507 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
15508 syms_of_callproc does the same thing. Remove test for
15509 "initialized", do it in the caller.
15510 * emacs.c (main): Avoid calling set_initial_environment when dumping.
15512 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
15514 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
15515 (read_minibuf): Use get_minibuffer.

15524 (CCL_CODE_MIN): New macro.
15526 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
15528 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
15530 * eval.c (Qdebug): Now static.
15531 * lisp.h (Qdebug): Remove decl. This reverts a part of the
15532 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
15533 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
15535 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
15537 * image.c: Various fixes to ImageMagick code comments.
15538 (Fimagemagick_types): Doc fix.
15540 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
15542 Minor fixes prompted by GCC 4.6.0 warnings.
15544 * xselect.c (converted_selections, conversion_fail_tag): Now static.
15546 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
15547 (x_clipboard_manager_save_all): Move extern decl to ...
15548 * xterm.h: ... here, so that it can be checked for consistency.
15550 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
15552 * xselect.c (x_clipboard_manager_save_frame)
15553 (x_clipboard_manager_save_all): New functions.
15554 (Fx_clipboard_manager_save): Lisp function deleted.
15556 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
15557 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
15559 * xterm.h: Update prototype.
15561 2011-05-28 William Xu <william.xwl@gmail.com>
15563 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
15564 exiting (Bug#8239).
15566 2011-05-28 Jim Meyering <meyering@redhat.com>
15568 Avoid a sign-extension bug in crypto_hash_function.
15569 * fns.c (to_uchar): Define.
15570 (crypto_hash_function): Use it to convert some newly-signed
15571 variables to unsigned, to avoid sign-extension bugs. For example,
15572 without this change, (md5 "truc") would evaluate to
15573 45723a2aff78ff4fff7fff1114760e62 rather than the expected
15574 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
15575 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
15577 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
15579 Integer overflow fixes.
15581 * dbusbind.c: Serial number integer overflow fixes.
15582 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
15583 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
15584 to hold a serial number that is too large for a fixnum.
15585 (Fdbus_method_return_internal, Fdbus_method_error_internal):
15586 Check for serial numbers out of range. Decode any serial number
15587 that was so large that it became a float. (Bug#8722)
15589 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
15590 (Fdbus_call_method, Fdbus_call_method_asynchronously):
15591 Use XFASTINT rather than XUINT when numbers are nonnegative.
15592 (xd_append_arg, Fdbus_method_return_internal):
15593 (Fdbus_method_error_internal): Likewise. Also, for unsigned
15594 arguments, check that Lisp number is nonnegative, rather than
15595 silently wrapping negative numbers around. (Bug#8722)
15596 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
15599 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
15601 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
15603 ccl: Add integer overflow checks.
15604 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
15605 (IN_INT_RANGE): New macros.
15606 (ccl_driver): Use them to check for integer overflow when
15607 decoding a CCL program. Many of the new checks are whether XINT (x)
15608 fits in int; it doesn't always, on 64-bit hosts. The new version
15609 doesn't catch all possible integer overflows, but it's an
15610 improvement. (Bug#8719)
15612 * alloc.c (make_event_array): Use XINT, not XUINT.
15613 There's no need for unsigned here.
15615 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
15616 This follows up to the 2011-05-06 change that substituted uintptr_t
15617 for EMACS_INT. This case wasn't caught back then.
15619 Rework Fformat to avoid integer overflow issues.
15620 * editfns.c: Include <float.h> unconditionally, as it's everywhere
15621 now (part of C89). Include <verify.h>.
15622 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
15623 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
15624 (Fformat): Avoid the prepass trying to compute sizes; it was only
15625 approximate and thus did not catch overflow reliably. Instead, walk
15626 through the format just once, formatting and computing sizes as we go,
15627 checking for integer overflow at every step, and allocating a larger
15628 buffer as needed. Keep track separately whether the format is
15629 multibyte. Keep only the most-recently calculated precision, rather
15630 than them all. Record whether each argument has been converted to
15631 string. Use EMACS_INT, not int, for byte and char and arg counts.
15632 Support field widths and precisions larger than INT_MAX. Avoid
15633 sprintf's undefined behavior with conversion specifications such as %#d
15634 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
15635 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
15636 formatting out-of-range floating point numbers with int
15637 formats. (Bug#8668)
15639 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
15641 * data.c: Avoid integer truncation in expressions involving floats.
15642 * data.c: Include <intprops.h>.
15643 (arith_driver): When there's an integer overflow in an expression
15644 involving floating point, convert the integers to floating point
15645 so that the resulting value does not suffer from catastrophic
15646 integer truncation. For example, on a 64-bit host (* 4
15647 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
15648 Do not rely on undefined behavior after integer overflow.
15650 merge count_size_as_multibyte, parse_str_to_multibyte
15651 * character.c, character.h (count_size_as_multibyte):
15652 Rename from parse_str_to_multibyte; all uses changed.
15653 Check for integer overflow.
15654 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
15655 since it's now a duplicate of the other. This is more of
15656 a character than a buffer op, so better that it's in character.c.
15657 * fns.c, print.c: Adjust to above changes.
15659 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
15661 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
15663 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
15665 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
15666 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
15667 (x_clipboard_manager_save): Now static.
15668 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
15670 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
15671 (crypto_hash_function): Now static.
15672 Fix pointer signedness problems. Avoid unnecessary initializations.
15674 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
15676 * termhooks.h (Vselection_alist): Make it terminal-local.
15678 * terminal.c (create_terminal): Initialize it.
15680 * xselect.c: Support for clipboard managers.
15681 (Vselection_alist): Move to termhooks.h as terminal-local var.
15682 (LOCAL_SELECTION): New macro.
15683 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
15684 (symbol_to_x_atom): Remove gratuitous arg.
15685 (x_handle_selection_request, lisp_data_to_selection_data)
15686 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
15687 (x_own_selection, x_get_local_selection, x_convert_selection):
15688 New arg, specifying work frame. Use terminal-local Vselection_alist.
15689 (some_frame_on_display): Delete unused function.
15690 (Fx_own_selection_internal, Fx_get_selection_internal)
15691 (Fx_disown_selection_internal, Fx_selection_owner_p)
15692 (Fx_selection_exists_p): New optional frame arg.
15693 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
15694 (x_handle_selection_clear): Don't treat other terminals with the
15695 same keyboard specially. Use the terminal-local Vselection_alist.
15696 (x_clear_frame_selections): Use Frun_hook_with_args.
15698 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
15700 * xterm.h: Add support for those atoms.
15702 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
15704 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
15705 (converted_selections, conversion_fail_tag): New global variables.
15706 (x_selection_request_lisp_error): Free the above.
15707 (x_get_local_selection): Remove unnecessary code.
15708 (x_reply_selection_request): Args changed; handle arbitrary array
15709 of converted selections stored in converted_selections.
15710 Separate the XChangeProperty and SelectionNotify steps.
15711 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
15712 (x_convert_selection): New function.
15713 (x_handle_selection_event): Simplify.
15714 (x_get_foreign_selection): Don't ignore incoming requests while
15715 waiting for an answer; this will fail when we implement
15716 SAVE_TARGETS, and seems unnecessary anyway.
15717 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
15718 (Vx_sent_selection_functions): Doc fix.
15720 2011-05-26 Leo Liu <sdl.web@gmail.com>
15722 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
15724 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15726 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
15728 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
15729 for fringe update if it has periodic bitmap.
15730 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
15731 and fringe_bitmap_periodic_p.
15733 * fringe.c (get_fringe_bitmap_data): New function.
15734 (draw_fringe_bitmap_1, update_window_fringes): Use it.
15735 (update_window_fringes): Record periodicity of fringe bitmap in glyph
15736 row. Mark glyph row for fringe update if periodicity changed.
15738 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
15739 for fringe update unless it has periodic bitmap.
15741 2011-05-25 Kenichi Handa <handa@m17n.org>
15743 * xdisp.c (get_next_display_element): Set correct it->face_id for
15744 a static composition.
15746 2011-05-24 Leo Liu <sdl.web@gmail.com>
15749 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
15751 * fns.c (crypto_hash_function, Fsha1): New function.
15752 (Fmd5): Use crypto_hash_function.
15753 (syms_of_fns): Add Ssha1.
15755 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
15757 * gnutls.c: Remove unused macros.
15758 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
15759 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
15760 Remove macros that are defined and never used.
15761 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
15763 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
15765 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
15766 (Fx_get_selection_internal): Minor cleanup.
15767 (Fx_own_selection_internal): Rename arguments for consistency with
15770 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
15772 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
15774 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
15776 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
15778 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15780 * dispnew.c (scrolling_window): Don't exclude the case that the
15781 last enabled row in the desired matrix touches the bottom boundary.
15783 2011-05-21 Glenn Morris <rgm@gnu.org>
15785 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
15786 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
15787 and add some more files.
15789 2011-05-20 Eli Zaretskii <eliz@gnu.org>
15791 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
15792 report_file_error introduced by the change from 2011-05-07.
15794 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
15796 * systime.h (Time): Define only if emacs is defined.
15797 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
15798 where the include path doesn't have X11/X.h by default. See
15799 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
15801 2011-05-20 Kenichi Handa <handa@m17n.org>
15803 * composite.c (find_automatic_composition): Fix previous change.
15805 2011-05-20 Glenn Morris <rgm@gnu.org>
15807 * lisp.mk: New file, split from Makefile.in.
15808 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
15809 (shortlisp): Remove.
15810 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
15812 2011-05-19 Glenn Morris <rgm@gnu.org>
15814 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
15815 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
15816 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
15817 (lisp): Set the order to that of loadup.el.
15818 (shortlisp): Make it a copy of $lisp.
15819 (SOME_MACHINE_LISP): Remove.
15820 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
15821 Use just $shortlisp, not $SOME_MACHINE_LISP too.
15823 2011-05-18 Kenichi Handa <handa@m17n.org>
15825 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
15826 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
15827 (find_automatic_composition): Mostly rewrite for efficiency.
15829 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
15831 * makefile.w32-in: Update dependencies.
15833 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
15835 * menu.c: Include limits.h (fixes the MS-Windows build broken by
15836 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
15838 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
15840 Fix some integer overflow issues, such as string length overflow.
15842 * insdel.c (count_size_as_multibyte): Check for string overflow.
15844 * character.c (lisp_string_width): Check for string overflow.
15845 Use EMACS_INT, not int, for string indexes and lengths; in
15846 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
15847 the resulting string length overflows an EMACS_INT; instead,
15848 report a string overflow if no precision given. When checking for
15849 precision exhaustion, use a check that cannot possibly have
15850 integer overflow. (Bug#8675)
15851 * character.h (lisp_string_width): Adjust to new signature.
15853 * alloc.c (string_overflow): New function.
15854 (Fmake_string): Use it. This doesn't change behavior, but saves
15855 a few bytes and will simplify future changes.
15856 * character.c (string_escape_byte8): Likewise.
15857 * lisp.h (string_overflow): New decl.
15859 Fixups, following up to the user-interface timestamp change.
15860 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
15861 for UI timestamps, instead of unsigned long.
15862 * msdos.c (mouse_get_pos): Likewise.
15863 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
15864 * w32gui.h (Time): Define by including "systime.h" rather than by
15865 declaring it ourselves. (Bug#8664)
15867 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
15868 * image.c (clear_image_cache): Likewise.
15870 * term.c (term_mouse_position): Don't assume time_t wraparound.
15872 Be more systematic about user-interface timestamps.
15873 Before, the code sometimes used 'Time', sometimes 'unsigned long',
15874 and sometimes 'EMACS_UINT', to represent these timestamps.
15875 This change causes it to use 'Time' uniformly, as that's what X uses.
15876 This makes the code easier to follow, and makes it easier to catch
15877 integer overflow bugs such as Bug#8664.
15878 * frame.c (Fmouse_position, Fmouse_pixel_position):
15879 Use Time, not unsigned long, for user-interface timestamps.
15880 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
15881 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
15882 * keyboard.h (last_event_timestamp): Likewise.
15883 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
15884 * menu.h (xmenu_show): Likewise.
15885 * term.c (term_mouse_position): Likewise.
15886 * termhooks.h (struct input_event.timestamp): Likewise.
15887 (struct terminal.mouse_position_hook): Likewise.
15888 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
15889 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
15890 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
15891 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
15892 what it was before.
15893 * menu.h, termhooks.h: Include "systime.h", for Time.
15895 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
15896 Don't assume that the difference between two unsigned long values
15897 can fit into an integer. At this point, we know button_down_time
15898 <= event->timestamp, so the difference must be nonnegative, so
15899 there's no need to cast the result if double-click-time is
15900 nonnegative, as it should be; check that it's nonnegative, just in
15901 case. This bug is triggered when events are more than 2**31 ms
15902 apart (about 25 days). (Bug#8664)
15904 * xselect.c (last_event_timestamp): Remove duplicate decl.
15905 (x_own_selection): Remove needless cast to unsigned long.
15907 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
15908 that always fit in int. Use a sentinel instead of a counter, to
15909 avoid a temp and to allay GCC's concerns about possible int overflow.
15910 * frame.h (struct frame): Use int for menu_bar_items_used
15911 instead of EMACS_INT, since it always fits in int.
15913 * menu.c (grow_menu_items): Check for int overflow.
15915 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
15917 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
15918 Before, the code was not consistent. These values cannot exceed
15919 2**31 - 1 so there's no need to make them unsigned.
15920 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
15921 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
15922 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
15924 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
15926 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
15927 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
15928 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
15929 presumably because the widths might not match.
15931 * window.c (size_window): Avoid needless test at loop start.
15933 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
15935 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
15937 2011-05-12 Drew Adams <drew.adams@oracle.com>
15939 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
15941 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15943 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
15944 `width' to `bar_area_x' and `bar_area_width', respectively.
15945 (x_scroll_run): Take account of fringe background extension.
15947 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
15948 Rename local vars `left' and `width' to `bar_area_x' and
15949 `bar_area_width', respectively.
15950 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
15951 background extension.
15953 2011-05-10 Jim Meyering <meyering@redhat.com>
15955 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
15957 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
15959 * image.c (Finit_image_library): Return t for built-in image types,
15960 like pbm and xbm. (Bug#8640)
15962 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
15964 * w32menu.c (set_frame_menubar): Fix submenu allocation.
15966 2011-05-07 Eli Zaretskii <eliz@gnu.org>
15968 * w32console.c (Fset_screen_color): Doc fix.
15969 (Fget_screen_color): New function.
15970 (syms_of_ntterm): Defsubr it.
15972 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
15973 unlink the temporary file if Fcall_process didn't create it in the
15975 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
15976 child process will be redirected to a file specified with `:file'.
15977 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
15978 cue to call_process_cleanup not to close that handle.
15980 2011-05-07 Ben Key <bkey76@gmail.com>
15982 * makefile.w32-in: The bootstrap-temacs rule now makes use of
15983 one of two shell specific rules, either bootstrap-temacs-CMD or
15984 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
15985 to the previous implementation of the bootstrap-temacs rule.
15986 The bootstrap-temacs-CMD rule is similar to the previous
15987 implementation of the bootstrap-temacs rule except that it
15988 makes use of the ESC_CFLAGS variable instead of the CFLAGS
15991 These changes, along with some changes to nt/configure.bat,
15992 nt/gmake.defs, and nt/nmake.defs, are required to extend my
15993 earlier fix to add support for --cflags and --ldflags options
15994 that include quotes so that it works whether make uses cmd or
15997 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
15999 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
16000 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
16002 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
16003 a string. Handle both cases.
16004 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
16005 (Fdbus_register_method): Use Qinvalid_function.
16007 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
16009 * makefile.w32-in: Update dependencies.
16010 (LISP_H): Add inttypes.h and stdin.h.
16011 (PROCESS_H): Add unistd.h.
16013 2011-05-06 Eli Zaretskii <eliz@gnu.org>
16015 * lread.c: Include limits.h (fixes the MS-Windows build broken by
16016 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
16018 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
16020 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
16022 * term.c (vfatal): Remove stray call to va_end.
16023 It's not needed and the C Standard doesn't allow it here anyway.
16025 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
16026 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
16028 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
16031 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
16033 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
16035 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
16037 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
16039 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
16041 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
16042 * charset.c (Fdefine_charset_internal): Don't initialize
16043 charset.code_space[15]. The value was garbage, on hosts with
16044 32-bit int (Bug#8600).
16046 * lread.c (read_integer): Be more consistent with string-to-number.
16047 Use string_to_number to do the actual conversion; this avoids
16048 rounding errors and fixes some other screwups. Without this fix,
16049 for example, #x1fffffffffffffff was misread as -2305843009213693952.
16050 (digit_to_number): Move earlier, for benefit of read_integer.
16051 Return -1 if the digit is out of range for the base, -2 if it is
16052 not a digit in any supported base. (Bug#8602)
16054 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
16056 * dispnew.c (scrolling_window): Return 1 if we scrolled,
16057 to match comment at start of function. This also removes a
16058 GCC warning about overflow in a 32+64-bit port.
16060 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
16062 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
16063 Reported by Stefan Monnier in
16064 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
16065 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
16066 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
16068 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
16069 (EMACS_UINTPTR): Likewise, with uintptr_t.
16071 * lisp.h: Prefer 64-bit EMACS_INT if available.
16072 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
16073 on 32-bit hosts that have 64-bit int, so that they can access
16075 However, temporarily disable this change unless the temporary
16076 symbol WIDE_EMACS_INT is defined.
16078 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
16080 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
16081 This removes an assumption that EMACS_INT and long are the same
16082 width as pointers. The assumption is true for Emacs porting targets
16083 now, but we want to make other targets possible.
16084 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
16085 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
16086 In the rest of the code, change types of integers that hold casted
16087 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
16088 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
16089 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
16090 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
16091 No need to cast type when ORing.
16092 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
16093 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
16094 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
16095 assume EMACS_INT is the same width as char *.
16096 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
16097 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
16098 Remove no-longer-needed casts.
16099 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
16100 (xg_tool_bar_help_callback, xg_make_tool_item):
16101 Use EMACS_INTPTR to hold an integer
16102 that will be cast to void *; this can avoid a GCC warning
16103 if EMACS_INT is not the same width as void *.
16104 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
16105 * xdisp.c (display_echo_area_1, resize_mini_window_1):
16106 (current_message_1, set_message_1):
16107 Use a local to convert to proper width without a cast.
16108 * xmenu.c (dialog_selection_callback): Likewise.
16110 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
16111 Also, don't assume VALBITS / RAND_BITS is less than 5,
16112 and don't rely on undefined behavior when shifting a 1 left into
16114 * lisp.h (get_random): Change signature to match.
16116 * lread.c (hash_string): Use size_t, not int, for hash computation.
16117 Normally we prefer signed values; but hashing is special, because
16118 it's better to use unsigned division on hash table sizes so that
16119 the remainder is nonnegative. Also, size_t is the natural width
16120 for hashing into memory. The previous code used 'int', which doesn't
16121 retain enough info to hash well into very large tables.
16122 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
16124 * dbusbind.c: Don't possibly lose pointer info when converting.
16125 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
16126 Use XPNTR rather than XHASH, so that the high-order bits of
16127 the pointer aren't lost when converting through void *.
16129 * eval.c (Fautoload): Don't double-shift a pointer.
16131 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
16133 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
16135 * gnutls.c (DEF_GNUTLS_FN):
16136 * image.c (DEF_IMGLIB_FN): Make function pointers static.
16138 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
16140 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
16143 2011-05-05 Eli Zaretskii <eliz@gnu.org>
16145 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:

16154 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
16155 `gnutls_certificate_set_x509_key_file'.
16157 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
16159 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
16160 Update dependencies.
16162 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
16164 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
16165 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
16166 Remove unused parameter `fildes'.
16167 * process.c (read_process_output, send_process): Don't pass it.
16169 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
16171 Fix previous change: the library cache is defined in w32.c.
16172 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
16173 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
16175 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
16177 Implement dynamic loading of GnuTLS on Windows.
16179 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
16180 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
16181 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
16184 * gnutls.c (Qgnutls_dll): Define.

16194 (Fgnutls_available_p): New function.
16195 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.

16205 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
16207 * w32.c (QCloaded_from, Vlibrary_cache): Define.
16208 (w32_delayed_load): Move from image.c. When loading a library, record
16209 its filename in the :loaded-from property of the library id.
16210 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
16211 Initialize and staticpro them.
16212 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
16214 * process.c: Include lisp.h before w32.h, not after.
16215 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
16216 instead of gnutls_record_check_pending.
16218 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
16220 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
16222 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
16223 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
16226 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
16228 * xterm.c (x_set_frame_alpha): Do not set property on anything
16229 else than FRAME_X_OUTER_WINDOW (Bug#8608).
16231 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
16233 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
16235 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
16237 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)

16261 * callproc.c (Fcall_process): Add (:file "file") as an option for
16263 (Fcall_process_region): Ditto.
16265 2011-04-30 Eli Zaretskii <eliz@gnu.org>
16267 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
16268 rather than `XVECTOR (FOO)->size'.
16270 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
16271 inttypes.h, as a gnulib replacement is used if it not available in
16274 2011-04-21 Eli Zaretskii <eliz@gnu.org>
16276 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
16277 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
16278 of MOST_POSITIVE_FIXNUM. (Bug#8528)
16280 * coding.c (coding_alloc_by_realloc): Error out if destination
16281 will grow beyond MOST_POSITIVE_FIXNUM.
16282 (decode_coding_emacs_mule): Abort if there isn't enough place in
16283 charbuf for the composition carryover bytes. Reserve an extra
16284 space for up to 2 characters produced in a loop.
16285 (decode_coding_iso_2022): Abort if there isn't enough place in
16286 charbuf for the composition carryover bytes.
16288 2011-04-21 Eli Zaretskii <eliz@gnu.org>
16290 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
16291 aborting when %lld or %lll format is passed.
16292 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
16293 %llo or %llx format is passed. (Bug#8545)
16295 * window.c (window_scroll_line_based): Use a marker instead of
16296 simple variables to record original value of point. (Bug#7952)
16298 * doprnt.c (doprnt): Fix the case where a multibyte sequence
16299 produced by %s or %c overflows available buffer space. (Bug#8545)
16301 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
16303 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).

16312 * keyboard.c (Qdelayed_warnings_hook): Define.
16313 (command_loop_1): Run `delayed-warnings-hook'
16314 if Vdelayed_warnings_list is non-nil.
16315 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
16316 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
16318 2011-04-28 Eli Zaretskii <eliz@gnu.org>
16320 * doprnt.c (doprnt): Don't return value smaller than the buffer
16321 size if the message was truncated. (Bug#8545).
16323 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
16325 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
16326 (Fx_window_property): #if-0 the whole functions, not just the bodies.
16328 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
16330 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
16332 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
16334 * makefile.w32-in: Update dependencies.
16336 2011-04-27 Eli Zaretskii <eliz@gnu.org>
16338 Improve `doprnt' and its usage. (Bug#8545)
16339 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
16340 `format_end'. Remove support for %l as a conversion specifier.
16341 Don't use xrealloc. Improve diagnostics when the %l size modifier
16342 is used. Update the commentary.
16344 * eval.c (verror): Simplify calculation of size_t.
16346 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
16349 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
16351 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
16354 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
16356 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
16357 This makes this file independent of the recent pseudovector change.
16359 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
16361 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
16363 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
16364 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
16365 Remove unused local.
16366 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
16368 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
16369 GCC 4.6.0 optimizes based on type-based alias analysis.
16370 For example, if b is of type struct buffer * and v of type struct
16371 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
16372 != &v->size, and therefore "v->size = 1; b->size = 2; return
16373 v->size;" must therefore return 1. This assumption is incorrect
16374 for Emacs, since it type-puns struct Lisp_Vector * with many other
16375 types. To fix this problem, this patch adds a new type struct
16376 vectorlike_header that documents the constraints on layout of vectors
16377 and pseudovectors, and helps optimizing compilers not get fooled
16378 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
16379 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
16380 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
16382 (XSETPVECTYPE): Rewrite in terms of new macro.
16383 (XSETPVECTYPESIZE): New macro, specifying both type and size.
16384 This is a bit clearer, and further avoids the possibility of
16385 undesirable aliasing.
16386 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
16387 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
16388 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
16389 since Lisp_Subr is a special case (no "next" field).
16390 (ASIZE): Now uses header.size rather than size.
16391 All previous uses of XVECTOR (foo)->size replaced to use this macro,
16392 to avoid the hassle of writing XVECTOR (foo)->header.size.
16393 (struct vectorlike_header): New type.
16394 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
16395 object, to help avoid aliasing.
16396 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
16397 (SUBRP): Likewise, since Lisp_Subr is a special case.
16398 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
16399 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
16400 (struct Lisp_Hash_Table): Combine first two members into a single
16401 struct vectorlike_header member. All uses of "size" and "next" members
16402 changed to be "header.size" and "header.next".
16403 * buffer.h (struct buffer): Likewise.
16404 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
16405 * frame.h (struct frame): Likewise.
16406 * process.h (struct Lisp_Process): Likewise.
16407 * termhooks.h (struct terminal): Likewise.
16408 * window.c (struct save_window_data, struct saved_window): Likewise.
16409 * window.h (struct window): Likewise.
16410 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
16411 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
16412 * buffer.c (init_buffer_once): Likewise.
16413 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
16415 * process.c (Fformat_network_address): Use local var for size,
16418 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
16420 Make the Lisp reader and string-to-float more consistent (Bug#8525)
16421 * data.c (atof): Remove decl; no longer used or needed.
16422 (digit_to_number): Move to lread.c.
16423 (Fstring_to_number): Use new string_to_number function, to be
16424 consistent with how the Lisp reader treats infinities and NaNs.
16425 Do not assume that floating-point numbers represent EMACS_INT
16426 without losing information; this is not true on most 64-bit hosts.
16427 Avoid double-rounding errors, by insisting on integers when
16428 parsing non-base-10 numbers, as the documentation specifies.
16429 * lisp.h (string_to_number): New decl, replacing ...
16430 (isfloat_string): Remove.
16431 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
16432 (read1): Do not accept +. and -. as integers; this
16433 appears to have been a coding error. Similarly, do not accept
16434 strings like +-1e0 as floating point numbers. Do not report
16435 overflow for integer overflows unless the base is not 10 which
16436 means we have no simple and reliable way to continue.
16437 Break out the floating-point parsing into a new
16438 function string_to_number, so that Fstring_to_number parses
16439 floating point numbers consistently with the Lisp reader.
16440 (digit_to_number): Move here from data.c. Make it static inline.
16441 (E_CHAR, EXP_INT): Remove, replacing with ...
16442 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
16443 (string_to_number): New function, replacing isfloat_string.
16444 This function checks for valid syntax and produces the resulting
16445 Lisp float number too. Rework it so that string-to-number
16446 no longer mishandles examples like "1.0e+". Use strtoumax,
16447 so that overflow for non-base-10 numbers is reported only when
16448 there's no portable and simple way to convert to floating point.
16450 * textprop.c (set_text_properties_1): Rewrite for clarity,
16451 and to avoid GCC warning about integer overflow.
16453 * intervals.h (struct interval): Use EMACS_INT for members
16454 where EMACS_UINT might cause problems. See
16455 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
16456 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
16457 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
16459 (offset_intervals): Tell GCC not to worry about length overflow
16460 when negating a negative length.
16462 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
16463 (overrun_check_free): Likewise.
16465 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
16466 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
16469 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
16470 (gnutls_make_error): Rename local to avoid shadowing.
16471 (gnutls_emacs_global_deinit): ifdef out; not used.
16472 (Fgnutls_boot): Use const for pointer to readonly storage.
16473 Comment out unused local. Fix pointer signedness problems.
16475 * lread.c (openp): Don't stuff size_t into an 'int'.
16476 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
16477 about possible signed overflow.
16479 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
16480 (GDK_KEY_g): Don't define if already defined.
16481 (xg_prepare_tooltip): Avoid pointer signedness problem.
16482 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
16484 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
16485 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
16487 * xfns.c (Fx_window_property): Simplify a bit,
16488 to make a bit faster and to avoid GCC 4.6.0 warning.
16489 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
16491 * fns.c (internal_equal): Don't assume size_t fits in int.
16493 * alloc.c (compact_small_strings): Tighten assertion a little.
16495 Replace pEd with more-general pI, and fix some printf arg casts.
16496 * lisp.h (pI): New macro, generalizing old pEd macro to other
16497 conversion specifiers. For example, use "...%"pI"d..." rather
16498 than "...%"pEd"...".
16499 (pEd): Remove. All uses replaced with similar uses of pI.
16500 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
16501 * alloc.c (check_pure_size): Don't overflow by converting size to int.
16502 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
16503 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
16504 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
16505 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
16506 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
16508 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
16509 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
16510 * print.c (safe_debug_print, print_object): Likewise.
16511 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
16513 Use pI instead of if-then-else-abort. Use %p to avoid casts,
16514 avoiding the 0 flag, which is not portable.
16515 * process.c (Fmake_network_process): Use pI to avoid cast.
16516 * region-cache.c (pp_cache): Likewise.
16517 * xdisp.c (decode_mode_spec): Likewise.
16518 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
16519 behavior on 64-bit hosts with printf arg.
16520 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
16521 (x_stop_queuing_selection_requests): Likewise.
16522 (x_get_window_property): Don't truncate byte count to an 'int'
16525 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
16526 here, since it parses constructs like leading '-' and spaces,
16527 which are not wanted; and it overflows with large numbers.
16528 Instead, simply match F[0-9]+, which is what is wanted anyway.
16530 * alloc.c: Remove unportable assumptions about struct layout.
16531 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
16532 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
16533 (allocate_vectorlike, make_pure_vector): Use the new macros,
16534 plus offsetof, to remove unportable assumptions about struct layout.
16535 These assumptions hold on all porting targets that I know of, but
16536 they are not guaranteed, they're easy to remove, and removing them
16537 makes further changes easier.
16539 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
16540 This doesn't fix a bug but makes the code clearer.
16541 (string_overrun_cookie): Now const. Use initializers that
16542 don't formally overflow signed char, to avoid warnings.
16543 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
16544 can cause Emacs to crash when string overrun checking is enabled.
16545 (allocate_buffer): Don't assume sizeof (struct buffer) is a
16546 multiple of sizeof (EMACS_INT); it need not be, if
16547 alignof(EMACS_INT) < sizeof (EMACS_INT).
16548 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
16550 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

16577 2011-04-25 Eli Zaretskii <eliz@gnu.org>
16579 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
16580 "cast to pointer from integer of different size".
16582 Improve doprnt and its use in verror. (Bug#8545)
16583 * doprnt.c (doprnt): Document the set of format control sequences
16584 supported by the function. Use SAFE_ALLOCA instead of always
16587 * eval.c (verror): Don't limit the buffer size at size_max-1, that
16588 is one byte too soon. Don't use xrealloc; instead xfree and
16591 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
16593 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the

16597 gnutls_global_initialized. Added internals for the
16598 :verify-hostname-error, :verify-error, and :verify-flags
16599 parameters of `gnutls-boot' and documented those parameters in the
16600 docstring. Start callback support.
16601 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
16602 unless a fatal error occurred. Call gnutls_alert_send_appropriate

16700 * callint.c (Fcall_interactively): When displaying error message
16701 about invalid control letter, pass the character's codepoint, not

16706 codepoint of an invalid character, to avoid displaying a bogus
16709 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
16710 `error', not SYMBOL_NAME itself.
16712 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for

16715 * charset.c (check_iso_charset_parameter): Fix incorrect argument
16716 to `error' in error message about FINAL_CHAR argument. Make sure
16717 FINAL_CHAR is a character, and use %c when it is passed as
16718 argument to `error'.
16720 2011-04-23 Eli Zaretskii <eliz@gnu.org>
16722 * s/ms-w32.h (localtime): Redirect to sys_localtime.
16724 * w32.c: Include <time.h>.

16784 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
16785 by pacifying GCC about it. Maybe it's time to retire it?
16786 * xfaces.c (USG, __TIMEVAL__): Likewise.
16788 * dispextern.h (struct redisplay_interface): Rename param
16789 to avoid shadowing.
16790 * termhooks.h (struct terminal): Likewise.

16905 2011-04-16 Ben Key <bkey76@gmail.com>
16907 * nsfont.m: Fixed bugs in ns_get_family and
16908 ns_descriptor_to_entity that were caused by using free to
16909 deallocate memory blocks that were allocated by xmalloc (via
16910 xstrdup). This caused Emacs to crash when compiled with
16911 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
16912 --enable-checking=xmallocoverrun). xfree is now used to
16913 deallocate these memory blocks.
16915 2011-04-15 Paul Eggert <eggert@cs.ucla.edu>
16917 * sysdep.c (emacs_read): Remove unnecessary check vs MAX_RW_COUNT.

16927 (emacs_read, emacs_write): Remove check for negative size, as the
16928 Emacs source code has been audited now.
16929 * sysdep.c (MAX_RW_COUNT): New macro, to work around kernel bugs.
16930 (emacs_read, emacs_write): Use it.
16931 * process.c (send_process): Adjust to the new signatures of
16932 emacs_write and emacs_gnutls_write. Do not attempt to store
16933 a byte offset into an 'int'; it might overflow.
16934 See http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00483.html

17359 * keyboard.c (Fthis_command_keys): Remove decl.
17360 (Fcommand_execute): New forward static decl.
17361 * keymap.c (Flookup_key): New forward static decl.
17362 (Fcopy_keymap): Now static.
17363 * keymap.h (Flookup_key): Remove decl.
17364 * process.c (Fget_process): New forward static decl.
17365 (Fprocess_datagram_address): Mark as internal.
17366 * syntax.c (Fsyntax_table_p): New forward static decl.

17381 2011-04-13 Eli Zaretskii <eliz@gnu.org>
17383 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
17384 when at ZV. (Bug#8487)
17386 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
17388 * charset.c (Fclear_charset_maps): Use xfree instead of free.
17390 * keyboard.c (parse_tool_bar_item): Likewise.
17391 * sound.c (sound_cleanup, alsa_close): Likewise.
17392 * termcap.c (tgetent): Likewise.
17393 * xfns.c (x_default_font_parameter): Likewise.
17394 * xsettings.c (read_and_apply_settings): Likewise.
17396 * alloc.c (overrun_check_malloc, overrun_check_realloc)
17397 (overrun_check_free): Protoize.
17399 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
17401 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
17402 since callers should never pass a negative size.
17403 Change the signature to match that of plain 'read' and 'write'; see
17404 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
17405 * lisp.h: Update prototypes of emacs_write and emacs_read.
17407 2011-04-11 Eli Zaretskii <eliz@gnu.org>
17409 * xdisp.c (redisplay_window): Don't try to determine the character
17410 position of the scroll margin if the window start point w->startp
17411 is outside the buffer's accessible region. (Bug#8468)
17413 2011-04-10 Eli Zaretskii <eliz@gnu.org>
17415 Fix write-region and its subroutines for buffers > 2GB.
17416 * fileio.c (a_write, e_write): Modify declaration of arguments and
17417 local variables to support buffers larger than 2GB.
17418 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
17420 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
17421 argument, local variables, and return value.
17423 * lisp.h: Update prototypes of emacs_write and emacs_read.
17425 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
17427 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
17429 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
17431 Fix more problems found by GCC 4.6.0's static checks.
17433 * xdisp.c (vmessage): Use a better test for character truncation.
17435 * charset.c (load_charset_map): <, not <=, for optimization,
17436 and to avoid potential problems with integer overflow.
17437 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
17438 * casetab.c (set_identity, shuffle): Likewise.
17439 * editfns.c (Fformat): Likewise.
17440 * syntax.c (skip_chars): Likewise.
17442 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
17443 This also lets GCC 4.6.0 generate slightly better loop code.
17445 * callint.c (Fcall_interactively): <, not <=, for optimization.
17446 (Fcall_interactively): Count the number of arguments produced,
17447 not the number of arguments given. This is simpler and lets GCC
17448 4.6.0 generate slightly better code.
17450 * ftfont.c: Distingish more carefully between FcChar8 and char.
17451 The previous code passed unsigned char * to a functions like
17452 strlen and xstrcasecmp that expect char *, which does not
17453 conform to the C standard.
17454 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
17455 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
17456 char * when the C standard requires it.
17458 * keyboard.c (read_char): Remove unused var.
17460 * eval.c: Port to Windows vsnprintf (Bug#8435).
17461 Include <limits.h>.
17462 (SIZE_MAX): Define if the headers do not.
17463 (verror): Do not give up if vsnprintf returns a negative count.
17464 Instead, grow the buffer. This ports to Windows vsnprintf, which
17465 does not conform to C99. Problem reported by Eli Zaretskii.
17466 Also, simplify the allocation scheme, by avoiding the need for
17467 calling realloc, and removing the ALLOCATED variable.
17469 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
17471 Remove invocations of doprnt, as Emacs now uses vsnprintf.
17472 But keep the doprint source code for now, as we might revamp it
17473 and use it again (Bug#8435).
17474 * lisp.h (doprnt): Remove.
17475 * Makefile.in (base_obj): Remove doprnt.o.
17476 * deps.mk (doprnt.o): Remove.
17478 error: Print 32- and 64-bit integers portably (Bug#8435).
17479 Without this change, on typical 64-bit hosts error ("...%d...", N)
17480 was used to print both 32- and 64-bit integers N, which relied on
17481 undefined behavior.
17482 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
17483 * lisp.h (error, verror): Mark as printf-like functions.
17484 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
17485 Report overflow in size calculations when allocating printf buffer.
17486 Do not truncate output string at its first null byte.
17487 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
17488 Truncate the output at a character boundary, since vsnprintf does not
17490 * charset.c (check_iso_charset_parameter): Convert internal
17491 character to string before calling 'error', since %c now has the
17493 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
17494 overflow when computing char to be passed to 'error'. Do not
17495 pass Lisp_Object to 'error'; pass the integer instead.
17496 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
17497 formatted with plain %d.
17499 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
17501 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
17503 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
17505 * xterm.c (x_catch_errors): Remove duplicate declaration.
17507 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
17509 * xdisp.c, lisp.h (message_nolog): Remove; unused.
17511 2011-04-10 Jim Meyering <meyering@redhat.com>
17513 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
17514 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
17515 return ssize_t not "int", and use size_t as the buffer length.
17516 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
17517 * gnutls.h: Update declarations.
17518 * process.c (read_process_output): Use ssize_t, to match.
17519 (send_process): Likewise.
17521 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
17523 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
17525 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
17527 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
17528 Use unsigned char, to match FcChar8 type definition.
17530 * xterm.c (handle_one_xevent):
17531 * xmenu.c (create_and_show_popup_menu):
17532 * xselect.c (x_decline_selection_request)
17533 (x_reply_selection_request): Avoid type-punned deref of X events.
17535 2011-04-09 Eli Zaretskii <eliz@gnu.org>
17537 Fix some uses of `int' instead of EMACS_INT.
17538 * search.c (string_match_1, fast_string_match)
17539 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
17540 (scan_buffer, find_next_newline_no_quit)
17541 (find_before_next_newline, search_command, Freplace_match)
17542 (Fmatch_data): Make some `int' variables be EMACS_INT.
17544 * xdisp.c (display_count_lines): 3rd argument and return value now
17545 EMACS_INT. All callers changed.
17546 (pint2hrstr): Last argument is now EMACS_INT.
17548 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
17549 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
17550 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
17551 (decode_coding_utf_16, decode_coding_emacs_mule)
17552 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
17553 (decode_coding_ccl, decode_coding_charset)
17554 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
17555 (decode_coding_iso_2022, decode_coding_emacs_mule)
17556 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
17557 <char_offset, last_offset>: Declare EMACS_INT.
17558 (encode_coding_utf_8, encode_coding_utf_16)
17559 (encode_coding_emacs_mule, encode_invocation_designation)
17560 (encode_designation_at_bol, encode_coding_iso_2022)
17561 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
17562 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
17564 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
17565 (encode_invocation_designation): Last argument P_NCHARS is now
17567 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
17568 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
17570 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
17573 * ccl.c (Fccl_execute_on_string): Declare some variables
17576 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
17578 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
17580 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
17582 * process.c (Fformat_network_address): Doc fix.
17584 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
17586 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
17588 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
17590 * keyboard.c (read_char): Call Lisp function help-form-show,
17591 instead of using internal_with_output_to_temp_buffer.
17592 (Qhelp_form_show): New var.
17593 (syms_of_keyboard): Use DEFSYM macro.
17595 * print.c (internal_with_output_to_temp_buffer): Function deleted.
17597 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
17599 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
17601 * process.c (Flist_processes): Remove to Lisp.
17602 (list_processes_1): Delete.
17604 2011-04-06 Eli Zaretskii <eliz@gnu.org>
17606 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
17608 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
17610 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
17612 Fix more problems found by GCC 4.6.0's static checks.
17614 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
17616 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
17618 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
17620 * xdisp.c (vmessage): Mark as a printf-like function.
17622 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
17624 * sound.c (sound_warning): Don't crash if arg contains a printf format.
17626 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
17627 printf-like functions.
17628 (tiff_load): Add casts to remove these marks before passing them
17629 to system-supplied API.
17631 * eval.c (Fsignal): Remove excess argument to 'fatal'.
17633 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
17634 This avoids several warnings with gcc -Wstrict-overflow.
17635 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
17636 directly, rather than having caller test rule sign. This avoids
17637 some unnecessary tests.
17638 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
17639 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
17640 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
17642 * xfont.c (xfont_text_extents): Remove var that was set but not used.
17643 (xfont_open): Avoid unnecessary tests.
17645 * composite.c (composition_gstring_put_cache): Use unsigned integer.
17647 * composite.h, composite.c (composition_gstring_put_cache):
17648 Use EMACS_INT, not int, for length.
17650 * composite.h (COMPOSITION_DECODE_REFS): New macro,
17651 breaking out part of COMPOSITION_DECODE_RULE.
17652 (COMPOSITION_DECODE_RULE): Use it.
17653 * composite.c (get_composition_id): Remove unused local vars,
17654 by using the new macro.
17656 * textprop.c (set_text_properties_1): Change while to do-while,
17657 since the condition is always true at first.
17659 * intervals.c (graft_intervals_into_buffer): Mark var as used.
17660 (interval_deletion_adjustment): Return unsigned value.
17663 * process.c (list_processes_1, create_pty, read_process_output):

17673 (update_syntax_table): Use unsigned instead of int.
17675 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
17676 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
17677 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
17679 * print.c (print_error_message): Avoid int overflow.
17681 * font.c (font_list_entities): Redo for clarity,
17682 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
17684 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
17685 (font_score): Avoid potential overflow in diff calculation.
17687 * fns.c (substring_both): Remove var that is set but not used.
17688 (sxhash): Redo loop for clarity and to avoid wraparound warning.
17690 * eval.c (funcall_lambda): Rename local to avoid shadowing.
17692 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
17693 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
17694 can always succeed if overflow has undefined behavior.
17696 * search.c (boyer_moore, wordify): Remove vars set but not used.
17697 (wordify): Omit three unnecessary tests.
17699 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
17700 All callers changed. This avoids the need for an unused var.
17702 * casefiddle.c (casify_region): Remove var that is set but not used.
17704 * dired.c (file_name_completion): Remove var that is set but not used.
17706 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
17708 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
17709 (Finsert_file_contents): Remove unnecessary code checking fd.
17711 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
17712 Check for integer overflow on size calculations.
17714 * buffer.c (Fprevious_overlay_change): Remove var that is set
17717 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
17718 Remove vars that are set but not used.
17719 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
17720 (timer_check_2): Mark vars as initialized.
17722 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
17724 * image.c (lookup_image): Remove var that is set but not used.
17725 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
17727 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
17728 that are set but not used.
17730 * xfns.c (make_invisible_cursor): Don't return garbage
17731 if XCreateBitmapFromData fails (Bug#8410).
17733 * xselect.c (x_get_local_selection, x_handle_property_notify):
17734 Remove vars that are set but not used.
17736 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
17737 (make_invisible_cursor): Initialize a possibly-uninitialized variable.

17746 (map_tty_color) [!defined MSDOS]: Likewise.
17748 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
17750 * coding.c: Remove vars that are set but not used.
17751 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
17752 All callers changed.
17753 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
17754 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
17755 (decode_coding_charset): Remove vars that are set but not used.
17757 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
17758 that is set but not used.
17760 * print.c (print_object): Remove var that is set but not used.
17762 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
17763 The gnulib version avoids calling malloc in the usual case,
17764 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
17765 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
17766 * filelock.c (current_lock_owner): Likewise.
17767 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
17768 * sysdep.c: Include allocator.h, careadlinkat.h.
17769 (emacs_no_realloc_allocator): New static constant.
17770 (emacs_readlink): New function.
17771 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
17772 ../lib/careadlinkat.h.
17774 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
17776 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
17777 first non-nil return value).
17779 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
17781 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
17782 if not defined (Bug#8403).
17784 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
17786 * xdisp.c (display_count_lines): Remove parameter `start',
17787 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
17788 (get_char_face_and_encoding): Remove parameter `multibyte_p',
17789 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

17791 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
17792 and thereabouts. All callers changed.
17793 (get_per_char_metric): Remove parameter `f', unused since
17794 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
17796 2011-04-02 Jim Meyering <meyering@redhat.com>
17798 do not dereference NULL upon failed strdup
17799 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
17800 (ns_get_family): Likewise.
17802 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
17804 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
17806 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
17808 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
17811 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
17813 Add lexical binding.
17815 * window.c (Ftemp_output_buffer_show): New fun.
17816 (Fsave_window_excursion):
17817 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
17819 * lread.c (lisp_file_lexically_bound_p): New function.
17820 (Fload): Bind Qlexical_binding.
17821 (readevalloop): Remove `evalfun' arg.
17822 Bind Qinternal_interpreter_environment.
17823 (Feval_buffer): Bind Qlexical_binding.
17824 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
17826 (syms_of_lread): Declare `lexical-binding'.
17828 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
17830 * keyboard.c (eval_dyn): New fun.
17831 (menu_item_eval_property): Use it.
17833 * image.c (parse_image_spec): Use Ffunctionp.
17835 * fns.c (concat, mapcar1): Accept byte-code-functions.
17837 * eval.c (Fsetq): Handle lexical vars.
17838 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
17839 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
17840 (FletX, Flet): Obey lexical binding.
17841 (Fcommandp): Handle closures.
17842 (Feval): New `lexical' arg.
17843 (eval_sub): New function extracted from Feval. Use it almost
17844 everywhere where Feval was used. Look up vars in lexical env.
17846 (Ffunctionp): Move from subr.el.
17847 (Ffuncall): Handle closures.
17848 (apply_lambda): Remove `eval_flags'.
17849 (funcall_lambda): Handle closures and new byte-code-functions.
17850 (Fspecial_variable_p): New function.
17851 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
17852 but without exporting it to Lisp.
17854 * doc.c (Fdocumentation, store_function_docstring):
17855 * data.c (Finteractive_form): Handle closures.
17857 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
17860 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
17862 (exec_byte_code): New function extracted from Fbyte_code to handle new
17863 calling convention for byte-code-functions. Add new byte-codes.
17865 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
17867 * alloc.c (Fmake_symbol): Init new `declared_special' field.
17869 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
17871 * xdisp.c (redisplay_internal): Fix prototype.
17873 2011-03-31 Eli Zaretskii <eliz@gnu.org>
17875 * xdisp.c (SCROLL_LIMIT): New macro.
17876 (try_scrolling): Use it when setting scroll_limit.
17877 Limit scrolling to 100 screen lines.
17878 (redisplay_window): Even when falling back on "recentering",
17879 position point in the window according to scroll-conservatively,
17880 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
17882 (try_scrolling): When point is above the window, allow searching
17883 as far as scroll_max, or one screenful, to compute vertical
17884 distance from PT to the scroll margin position. This prevents
17885 try_scrolling from unnecessarily failing when
17886 scroll-conservatively is set to a value slightly larger than the
17887 window height. Clean up the case of PT below the margin at bottom
17888 of window: scroll_max can no longer be INT_MAX. When aggressive
17889 scrolling is in use, don't let point enter the opposite scroll
17890 margin as result of the scroll.
17891 (syms_of_xdisp) <scroll-conservatively>: Document the
17892 threshold of 100 lines for never-recentering scrolling.
17894 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
17896 * dispextern.h (move_it_by_lines):
17897 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
17898 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
17899 (message_log_check_duplicate): Remove parameters `prev_bol' and
17900 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
17901 (redisplay_internal): Remove parameter `preserve_echo_area',
17902 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
17904 * indent.c (Fvertical_motion):
17905 * window.c (window_scroll_pixel_based, Frecenter):
17906 Don't pass `need_y_p' to `move_it_by_lines'.
17908 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
17910 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
17911 steal a few bits to be more compact.
17912 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
17913 Remove unneeded casts.
17915 * bytecode.c (Fbyte_code): CAR and CDR can GC.
17917 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
17919 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
17920 binding" message (bug#7967).
17922 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
17924 Fix more problems found by GCC 4.6.0's static checks.
17926 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
17927 Remove unused local var.
17929 * editfns.c (Fmessage_box): Remove unused local var.
17931 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
17932 (note_mode_line_or_margin_highlight, note_mouse_highlight):
17933 Omit unused local vars.
17934 * window.c (shrink_windows): Omit unused local var.
17935 * menu.c (digest_single_submenu): Omit unused local var.
17936 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
17937 Omit unused local var.
17939 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
17940 Don't assume string length fits in int.
17941 (keyremap_step, read_key_sequence): Use size_t for sizes.
17942 (read_key_sequence): Don't check last_real_key_start redundantly.
17944 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
17945 instead of alloca (Bug#8344).
17947 * eval.c (Fbacktrace): Don't assume nargs fits in int.
17948 (Fbacktrace_frame): Don't assume nframes fits in int.
17950 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
17952 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
17955 * term.c (produce_glyphless_glyph): Remove unnecessary test.
17957 * cm.c (calccost): Turn while-do into do-while, for clarity.
17959 * keyboard.c (syms_of_keyboard): Use the same style as later
17960 in this function when indexing through an array. This also
17961 works around GCC bug 48267.
17963 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
17965 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
17967 * chartab.c (sub_char_table_ref_and_range): Redo for slight
17968 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
17970 * keyboard.c, keyboard.h (num_input_events): Now size_t.
17971 This avoids undefined behavior on integer overflow, and is a bit
17972 more convenient anyway since it is compared to a size_t variable.
17974 Variadic C functions now count arguments with size_t, not int.
17975 This avoids an unnecessary limitation on 64-bit machines, which
17976 caused (substring ...) to crash on large vectors (Bug#8344).
17977 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
17978 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

17983 * eval.c (struct backtrace.nargs, interactive_p)
17984 (internal_condition_case_n, run_hook_with_args, apply_lambda)
17985 (funcall_lambda, mark_backtrace): Likewise.
17986 * fns.c (concat): Likewise.
17987 * frame.c (x_set_frame_parameters): Likewise.
17988 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
17989 0 if not found, not -1. All callers changed.
17991 * alloc.c (garbage_collect): Don't assume stack size fits in int.
17992 (stack_copy_size): Now size_t, not int.
17993 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
17995 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
17997 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
17998 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
17999 All callers changed.
18001 * lisp.h (multibyte_char_to_unibyte):
18002 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
18003 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
18004 * character.h (CHAR_TO_BYTE8):
18005 * cmds.c (internal_self_insert):
18006 * editfns.c (general_insert_function):
18007 * keymap.c (push_key_description):
18008 * search.c (Freplace_match):
18009 * xdisp.c (message_dolog, set_message_1): All callers changed.
18011 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
18013 * keyboard.c (safe_run_hook_funcall): New function.
18014 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
18015 don't set the hook to nil, but remove the offending function instead.
18016 (Qcommand_hook_internal): Remove, unused.
18017 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
18018 Vcommand_hook_internal.
18020 * eval.c (enum run_hooks_condition): Remove.
18021 (funcall_nil, funcall_not): New functions.
18022 (run_hook_with_args): Call each function through a `funcall' argument.
18023 Remove `cond' argument, now redundant.
18024 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
18025 (Frun_hook_with_args_until_failure): Adjust accordingly.
18026 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
18028 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
18030 * dispextern.h (string_buffer_position): Remove declaration.
18032 * print.c (strout): Remove parameter `multibyte', unused since
18033 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
18035 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
18036 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
18037 All callers changed.
18039 * w32.c (_wsa_errlist): Use braces for struct initializers.
18041 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
18042 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
18043 All callers changed.
18044 (string_buffer_position): Likewise. Also, make static (it's never
18045 used outside xdisp.c).
18046 (cursor_row_p): Remove parameter `w', unused since
18047 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.

18049 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
18050 All callers changed.
18052 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
18054 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.

18060 (ns_update_auto_hide_menu_bar): New functions.
18061 (ns_update_begin): Call ns_update_auto_hide_menu_bar.

18065 (syms_of_nsterm): DEFVAR ns-auto-hide-menu-bar, init to Qnil.
18067 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
18069 * nsmenu.m (runDialogAt): Remove argument to timer_check.
18071 2011-03-27 Glenn Morris <rgm@gnu.org>
18073 * syssignal.h: Replace RETSIGTYPE with void.
18074 * atimer.c, data.c, dispnew.c, emacs.c, floatfns.c, keyboard.c:
18075 * keyboard.h, lisp.h, process.c, sysdep.c, xterm.c:
18076 Replace SIGTYPE with void everywhere.
18077 * s/usg5-4-common.h (SIGTYPE): Remove definition.

18080 2011-03-26 Eli Zaretskii <eliz@gnu.org>
18082 * xdisp.c (redisplay_window): Don't check buffer's clip_changed
18083 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
18085 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
18087 * w32.c (read_unc_volume): Use parameter `henum', instead of
18088 global variable `wget_enum_handle'.
18090 * keymap.c (describe_vector): Remove parameters `indices' and
18091 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.
18092 (describe_map, Fdescribe_vector): Adjust calls to `describe_vector'.
18094 * keyboard.h (timer_check, show_help_echo): Remove unused parameters.
18096 * keyboard.c (timer_check): Remove parameter `do_it_now',
18097 unused since 1996-04-12T06:01:29Z!rms@gnu.org.
18098 (show_help_echo): Remove parameter `ok_to_overwrite_keystroke_echo',
18099 unused since 2008-04-19T19:30:53Z!monnier@iro.umontreal.ca.
18101 * keyboard.c (read_char):
18102 * w32menu.c (w32_menu_display_help):
18103 * xmenu.c (show_help_event, menu_help_callback):
18104 Adjust calls to `show_help_echo'.
18106 * gtkutil.c (xg_maybe_add_timer):
18107 * keyboard.c (readable_events):
18108 * process.c (wait_reading_process_output):
18109 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
18111 * insdel.c (adjust_markers_gap_motion):
18112 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.
18113 (gap_left, gap_right): Don't call it.
18115 2011-03-25 Chong Yidong <cyd@stupidchicken.com>

18159 2011-03-24 Juanma Barranquero <lekktu@gmail.com>
18161 * w32term.c (x_set_glyph_string_clipping):
18162 Don't pass uninitialized region to CombineRgn.
18164 2011-03-23 Juanma Barranquero <lekktu@gmail.com>
18166 * w32fns.c (x_set_menu_bar_lines): Remove unused variable `olines'.

18184 (uniscribe_font_driver): Add missing initializers.
18186 2011-03-23 Julien Danjou <julien@danjou.info>
18188 * term.c (Fsuspend_tty, Fresume_tty):
18189 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
18190 * window.c (temp_output_buffer_show):
18191 * insdel.c (signal_before_change):
18192 * frame.c (Fhandle_switch_frame):
18193 * fileio.c (Fdo_auto_save):
18194 * emacs.c (Fkill_emacs):
18195 * editfns.c (save_excursion_restore):
18196 * cmds.c (internal_self_insert):
18197 * callint.c (Fcall_interactively):
18198 * buffer.c (Fkill_all_local_variables):
18199 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
18201 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
18202 unconditionally since it does the check itself.
18204 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
18206 Fix more problems found by GCC 4.5.2's static checks.
18208 * coding.c (encode_coding_raw_text): Avoid unnecessary test
18209 the first time through the loop, since we know p0 < p1 then.
18210 This also avoids a gcc -Wstrict-overflow warning.
18212 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
18213 leading to a memory leak, possible in functions like
18214 load_charset_map_from_file that can allocate an unbounded number
18215 of objects (Bug#8318).
18217 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
18218 that could (at least in theory) be that large.
18220 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
18221 This is less likely to overflow, and avoids undefined behavior if
18222 overflow does occur. All callers changed. Use strtoul to scan
18223 for the unsigned long integer.
18224 (pint2hrstr): Simplify and tune code slightly.
18225 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
18227 * scroll.c (do_scrolling): Work around GCC bug 48228.
18228 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
18230 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
18231 This also avoids a warning with gcc -Wstrict-overflow.
18232 (validate_x_resource_name): Simplify count usage.
18233 This also avoids a warning with gcc -Wstrict-overflow.
18235 * fileio.c (Fcopy_file): Report error if fchown or fchmod
18238 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
18240 * process.c (Fmake_network_process): Use socklen_t, not int,
18241 where POSIX says socklen_t is required in portable programs.
18242 This fixes a porting bug on hosts like 64-bit HP-UX, where
18243 socklen_t is wider than int (Bug#8277).
18244 (Fmake_network_process, server_accept_connection):
18245 (wait_reading_process_output, read_process_output):
18248 * process.c: Rename or move locals to avoid shadowing.
18249 (list_processes_1, Fmake_network_process):
18250 (read_process_output_error_handler, exec_sentinel_error_handler):
18251 Rename or move locals.
18252 (Fmake_network_process): Define label "retry_connect" only if needed.

18320 clobbering (Bug#8298).
18321 * sysdep.c (sys_subshell): Likewise.
18322 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
18324 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
18325 This should get cleaned up, so that child_setup has the
18326 same signature on all platforms.
18328 * callproc.c (call_process_cleanup): Now static.
18329 (relocate_fd): Rename locals to avoid shadowing.

18500 to use the following functions instead of these macros.
18501 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
18502 EMACS_INT, since callers assume the returned value fits in int.
18503 (upcase1): Likewise, for UPCASE_TABLE.
18504 (uppercasep, lowercasep, upcase): New static inline functions.
18505 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

18515 (regex_compile, re_match_2_internal): Mark locals as initialized.
18516 (RETALLOC_IF): Define only if needed.
18517 (WORDCHAR_P): Likewise. This one is never needed, but is used
18518 only in a comment talking about a compiler bug, so put inside
18519 the #if 0 of that comment.
18520 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
18521 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

18548 New macros, so that the caller can use some names other than
18549 gcpro1, gcpro2, etc.
18550 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
18552 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
18553 argument, for consistency with GCPRO2_VAR, etc: it is now the
18554 prefix of the variable, not the variable itself. All uses
18556 * dired.c (directory_files_internal, file_name_completion):
18557 Rename locals to avoid shadowing.
18559 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
18560 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
18561 dired.c's scmp function, had undefined behavior.
18562 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
18563 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
18564 * buffer.h: ... to here, because these macros use current_buffer,
18565 and the new implementation with inline functions needs to have
18566 current_buffer in scope now, rather than later when the macros
18568 (downcase, upcase1): New static inline functions.
18569 (DOWNCASE, UPCASE1): Reimplement using these functions.
18570 This avoids undefined behavior in expressions like
18571 DOWNCASE (x) == DOWNCASE (y), which previously suffered
18572 from race conditions in accessing the global variables
18573 case_temp1 and case_temp2.
18574 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
18575 * lisp.h (case_temp1, case_temp2): Remove their decls.
18576 * character.h (ASCII_CHAR_P): Move from here ...

18589 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
18591 (Fset_file_times, Finsert_file_contents, auto_save_error):

18601 so that gcc does not warn that these functions aren't declared.

18604 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.

18611 * buffer.c (fix_overlays_before): Mark locals as initialized.
18612 (fix_start_end_in_overlays): Likewise. This function should be
18613 simplified by using pointers-to-pointers, but that's a different

18616 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
18617 (report_overlay_modification): Rename locals to avoid shadowing.

18626 * systty.h: ... to here, so that they can be checked.
