3 Avoid overflow in w32 implementation of interval timers. When
4 possible, for ITIMER_PROF count only times the main thread
6 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
7 'volatile ULONGLONG' types. All the other data which was
8 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
9 (GetThreadTimes_Proc): New typedef.
10 (w32_get_timer_time): New function, returns a suitable time value
12 (timer_loop): Enter critical section when accessing ULONGLONG
13 values of the itimer_data struct, as these accesses are no longer
14 atomic. Call 'w32_get_timer_time' instead of 'clock'.
15 (init_timers): Initialize s_pfn_Get_Thread_Times.
16 (start_timer_thread): Don't assign itimer->caller_thread here.
17 (getitimer): Assign itimer->caller_thread here.
18 (setitimer): Always call getitimer to get the value of ticks_now.
20 2012-10-26 Eli Zaretskii <eliz@gnu.org>
22 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
23 mouse movement events if the menu bar is active. This avoids
24 producing a busy "hour-glass" cursor by Windows if the mouse
25 pointer is positioned over a tooltip shown for some menu item.
27 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
29 Don't assume process IDs fit in int.
30 * emacs.c (shut_down_emacs) [!DOS_NT]:
31 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
32 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
33 Use pid_t, not int, to store process IDs, as 'int'
34 is not wide enough on a few platforms (e.g., AIX and IRIX).
36 2012-10-23 Kenichi Handa <handa@gnu.org>
38 The following change is to make face-font-rescale-alist work
39 correctly for non-ASCII fonts.

64 * frame.c (Fmouse_position, Fmouse_pixel_position):
65 * xdisp.c (produce_stretch_glyph):
66 Declare local vars only when they're needed.
67 This is clearer and avoids a warning on OpenBSD about unused vars.
68 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
69 This is safer, and avoids OpenBSD warnings about unused vars.
70 * keyboard.c (record_menu_key): Remove unnecessary decl.
71 (poll_timer): Define only if POLL_FOR_INPUT is defined.
72 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
73 as our definition clashes with OpenBSD's.
74 * xfaces.c (load_face_colors, check_lface_attrs)
75 (get_lface_attributes_no_remap, get_lface_attributes)
76 (lface_fully_specified_p, x_supports_face_attributes_p)
77 (tty_supports_face_attributes_p, face_fontset, realize_face)
78 (realize_x_face, realize_tty_face):
79 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
80 merely Lisp_Object *. This is more informative and avoids
81 a warning on OpenBSD about accessing beyond an object's size.
83 2012-10-20 Chong Yidong <cyd@gnu.org>
85 * lread.c (Fload): Doc fix (Bug#12592).

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

431 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
432 build that caused Emacs to display the hourglass cursor forever.
434 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
435 which is broken under remote desktop, calculate the number of
436 colors available for a display based on the display's number of

508 (ROUND_UP, ROUND_DOWN, get_page_size)
509 (get_allocation_unit, get_processor_type, get_w32_major_version)
510 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
511 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
512 (OS_NT, os_subtype, cache_system_info): Move here.
514 * unexw32.c, unexcw.c: Include w32common.h.
516 * emacs.c (main): Use (defined (WINDOWSNT) || defined
517 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
518 to call syms_of_w32select.
520 * cygw32.h: Remove obsolete EXFUN declarations.
522 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
524 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
525 of w32inevt.o from SOME_MACHINE_OBJECTS.
527 2012-10-08 Daniel Colascione <dancol@dancol.org>
529 * image.c: Permanent fix for JPEG compilation issue --- limit
530 jpeglib `boolean' redefinition to Cygwin builds.
532 2012-10-08 Eli Zaretskii <eliz@gnu.org>
534 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
536 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
539 2012-10-08 Daniel Colascione <dancol@dancol.org>
541 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
542 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
543 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
544 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
545 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
546 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
547 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
548 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
549 now a supported configuration.
551 * Makefile.in: consolidate image variables into LIBIMAGE; add
552 W32_OBJ and W32_LIBS. Compile new files.
555 (_DebPrint) declare tracing facility for W32 debugging. We need
556 to unify tracing later.
558 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
559 unconditional use of W32 Unicode functions. Cygwin runs only on
560 100% Unicode operating systems.
562 * cygw32.c: New file. Define Cygwin-specific facilities.
563 (Fcygwin_convert_path_to_windows)
564 (Fcygwin_convert_path_from_windows): New user functions for
565 accessing Cygwin path-munging routines.
567 * cygw32.h: New file.
568 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
569 UTF-16LE strings temporarily inside non-Lisp-visible string
572 (w32_strerror): Just what it says on the tin.
574 * emacs.c: Make the NS fork-then-exec code for daemon-launching
575 also run for Cygwin; both systems have the same problem with using
576 GUI facilities in a forked child. Also call syms_of_cygw32,
577 syms_of_w32select in correct places.
579 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
580 needs fork-then-exec for daemon launching.
582 * font.h: Include frame.h.
584 * image.c: Use the image library cache machinery only when we're
585 compiling for native WINDOWSNT; Cygwin can use shared libraries
586 like any other Unixlike system.
588 * keyboard.c: Clarify a comment regarding the input loop.
590 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
591 functions directly instead of trying to detect at runtime that our
592 host operating system supports them. We make this change for two
593 reasons: Cygwin lacks support for the multibyte character
594 conversion functions used by the legacy menu code, and Cygwin
595 never needs to rely on non-Unicode APIs.
597 * unexw32.c (hinst): Declare extern.
599 * w32.c: Change header order;
600 (w32_strerror): Move to w32fns.c because we need it for
601 non-WINDOWSNT builds.
603 * w32.h: Add #error macro to make sure we don't include w32.h for
604 Cygwin builds. Remove w32select declarations.
606 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
607 w32fns.c. w32console.c is WINDOWSNT-only.
609 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
610 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
612 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
613 (w32_major_version, w32_minor_version, w32_build_number)
614 (os_subtype, sound_type): Define here
615 (w32_defined_color): Make color parameter const for consistency
616 with other _defined_color functions.
617 (w32_createwindow): Unconditionally call w32_init_class instead of
618 doing so only when hprevinst is non-NULL. Plumbing hprevinst
619 through the code is complex and unnecessary because class
620 registration is practically free.
621 (w32_name_of_message): New EMACSDEBUG-only function.
622 (Fset_message_beep): Move here
623 (Fx_open_connection): Require that the display name for Windows be
624 "w32" for consistency, emacsclient disambiguation, and maybe, one
625 day, multi-window-system support.
626 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
627 Cygwin files for W32 GUI facilities, since these clearly don't
630 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
631 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
632 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
633 (w32_last_error): Remove.
635 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
637 * w32heap.c (syspage_mask): Declare here.
638 (cache_system_info): Remove.
640 * w32inevt.c (faked_key): Define globally, not statically.
641 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
642 (w32_console_toggle_lock_key): Move to w32fns.c.
644 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
646 * w32proc.c (_DebPrint): Move to w32fns.c.
647 * w32select.c: Include string.h, stdio.h for Cygwin.
648 * w32select.h: New File.
650 * w32term.c: Include io.h for non-CYGWIN builds; needed for
652 (w32_message_fd): New variable. Under Cygwin, holds the file
653 descriptor the system used to tell us about pending thread
656 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
657 that prevented compilation under non-WINDOWSNT systems.
659 (w32_initialize): Open /dev/windows and assign it to
660 w32_message_fd. Provide w32 feature.
662 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
663 (WM_EMACS_INPUT_READY): add.
664 (prepend_msg, w32_message_fd): Declare globally.
667 (keyboard_handle): Use only when WINDOWSNT.
668 (notify_msg_ready): New function. Posts a message to the main
669 thread's message queue under CYGWIN, which wakes up the main
670 thread from select(2) by making the /dev/windows file descriptor
671 ready. Under WINDOWSNT, it sets an event the same way the old
674 (post, prepend_msg): Actually call notify_msg_ready instead of
675 setting the input event directly.
677 2012-10-07 Eli Zaretskii <eliz@gnu.org>
679 * ralloc.c (relinquish): If a heap is ready to be relinquished,
680 but it still has blocs in it, don't return it to the system,
681 instead of aborting. (Bug#12402)
683 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
685 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
687 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
688 MAC_OS_X_VERSION_10_6.
689 (syms_of_nsterm): Remove comment about Panther and above for
691 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
692 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
693 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
695 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
696 MAC_OS_X_VERSION_10_4.
698 * nsmenu.m (fillWithWidgetValue:): Remove code for <
699 MAC_OS_X_VERSION_10_2.
701 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
703 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
704 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
706 * nsterm.m (ns_in_resize): Remove (Bug#12479).
707 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
708 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
709 Remove ns_in_resize check.
710 (ns_clear_frame_area): Remove resize handle code.
712 * nsfns.m (ns_in_resize): Remove.
713 (x_set_icon_name, ns_set_name, ns_set_name_as_filename): Remove
716 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
718 Improve sys_siglist detection.
719 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
720 defined as a macro, as is done in Solaris.
721 (sys_siglist_entries): New macro.
722 (save_strsignal): Use it.
723 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
724 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
726 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
728 * nsfns.m (Fx_create_frame): Call x_default_parameter with
729 fullscreen/Fullscreen.
731 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
734 * nsterm.m (x_make_frame_visible): Check for fullscreen.
735 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
736 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
737 (windowDidResize:): Check for correct window if old style fullscreen.
738 Capitalize word in comment. Remove incorrect comment.
739 (initFrameFromEmacs:): tbar_height renamed tibar_height.
740 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
741 error in drawing background.
742 (toggleFullScreen:): Remove comment. Rearrange calls.
743 Set toolbar values to zero, save old height in tobar_height.
744 Restore tool bar height when leaving fullscreen.
745 (canBecomeMainWindow): New function.
747 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
749 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
751 2012-10-05 Eli Zaretskii <eliz@gnu.org>
753 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
755 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
756 that time stamps of directories could also be changed.
757 Don't request the too broad GENERIC_WRITE, only the more restrictive
758 FILE_WRITE_ATTRIBUTES access rights.
760 * fileio.c (Fset_file_times): Special-case ignoring errors for
761 directories only on MSDOS, not on MS-Windows.
763 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
765 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
767 2012-10-04 Eli Zaretskii <eliz@gnu.org>
769 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
770 see whether CreateFile failed.
772 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
774 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
775 to avoid similar races.
776 * keyboard.c (pending_signals): Now bool, not int.
778 Port timers to OpenBSD, plus check for timer failures.
779 OpenBSD problem reported by Han Boetes.
780 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
782 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
783 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
784 like OpenBSD, which has timer_settime but does not declare it.
785 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
786 whether to use itimerspec-related primitives. All uses of
787 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
789 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
791 * profiler.c (handle_profiler_signal): Fix a malloc race
792 that caused Emacs to hang on Fedora 17 when profiling Lisp.
794 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
796 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
798 2012-10-02 Eli Zaretskii <eliz@gnu.org>
800 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
801 consistent with the change in return value of 'safe_strsignal'.
803 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
805 Prefer plain 'static' to 'static inline' (Bug#12541).
806 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
807 (bidi_set_sor_type, bidi_push_embedding_level)
808 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
809 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)

812 (bidi_peek_at_next_level, bidi_set_paragraph_end)
813 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
814 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
815 Now 'static', not 'static inline'.
817 Count overruns when profiling; change units to ns.
818 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
819 Give extra weight to samples after overruns, to attempt to count
820 the time more accurately.
821 (setup_cpu_timer): Change sampling interval units from ms to ns, since
822 the underlying primitives nominally do ns.
823 (Fprofiler_cpu_start): Document the change. Mention that
824 the sampling intervals are only approximate.
826 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
828 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
830 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
831 case for the special 0 coding-system.
833 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
834 (Fmake_overlay): Remove redundant tests.
835 (fix_start_end_in_overlays): Remove redundant recentering.
837 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
839 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
842 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
844 Fix a malloc race condition involving strsignal.
845 A signal can arrive in the middle of a malloc, and Emacs's signal
846 handler can invoke strsignal, which can invoke malloc, which is
847 not portable. This race condition bug makes Emacs hang on GNU/Linux.
848 Fix it by altering the signal handler so that it does not invoke
850 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
851 * process.c (status_message): Use const pointer, in case strsignal
852 is #defined to safe_strsignal.
853 * sysdep.c (sys_siglist, init_signals): Always define and
854 initialize a substitute sys_siglist if the system does not define
855 one, even if HAVE_STRSIGNAL.
856 (safe_strsignal): Rename from strsignal. Always define,
857 using sys_siglist. Return a const pointer.
858 * syssignal.h (safe_strsignal): New decl.
859 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
861 2012-10-01 Eli Zaretskii <eliz@gnu.org>
863 * w32proc.c (timer_loop): Fix code that waits for timer
864 expiration, to avoid high CPU usage.
866 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
868 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
869 (sweep_weak_table): Remove redundant prototypes.
871 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
873 * emacs.c: Move the inclusion of TERM_HEADER after including
874 windows.h on WINDOWSNT. This avoids compilation problems with
877 2012-10-01 Eli Zaretskii <eliz@gnu.org>
879 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
880 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
881 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
882 as the previous version used 'void *'.
884 * ralloc.c (ROUNDUP): Fix last change.
885 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
888 * w32proc.c <disable_itimers>: New static flag.
889 (init_timers): Initialize it to zero, after creating the critical
890 sections used by the timer threads.
891 (term_timers): Set to 1 before deleting the critical sections.
892 (getitimer, setitimer): If disable_itimers is non-zero, return an
893 error indication without doing anything. Reported by Fabrice
894 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
895 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
897 [!HAVE_SETITIMER]: Behave as the previous version that didn't
900 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
901 term_ntproc after all the other bookkeeping, to get timers working
904 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
906 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
907 Suggested by Juri Linkov in
908 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
910 Prefer plain 'static' to 'static inline' (Bug#12541).
911 With static functions, modern compilers inline pretty well by
912 themselves; advice from programmers often hurts as much as it helps.
913 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
914 this change shrinks the text size of the Emacs executable by 1.1%
915 without affecting CPU significantly in my benchmark.

1214 for consistency with other handlers.
1215 (setup_cpu_timer): New function, with much of what used to be in

1217 Prefer timer_settime if available, and prefer
1218 thread cputime clocks, then process cputime clocks, then
1219 monotonic clocks, to the old realtime clock. Use make_timeval
1220 to round more-correctly when falling back to setitimer.
1221 (Fprofiler_cpu_start): Use it.
1222 (Fprofiler_cpu_stop): Prefer timer_settime if available.

1438 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
1440 Move pid_t related decls out of lisp.h.
1441 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
1442 (interruptible_wait_for_termination):
1443 Move these decls from lisp.h to syswait.h, since they use pid_t.
1444 Needed on FreeBSD; see Herbert J. Skuhra in
1445 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
1446 * callproc.c: Include syswait.h.
1448 gnutls.c, gtkutil.c: Use bool for boolean.
1449 * gnutls.c (gnutls_global_initialized, init_gnutls_functions)
1450 (emacs_gnutls_handle_error):
1451 * gtkutil.c (xg_check_special_colors, xg_prepare_tooltip)
1452 (xg_hide_tooltip, xg_create_frame_widgets)

1461 (update_frame_tool_bar, free_frame_tool_bar):
1462 * gtkutil.c, w32term.c, xterm.c (x_wm_set_size_hint):
1463 * nsmenu.m (ns_update_menubar):
1464 * nsmenu.m, w32menu.c, xmenu.c (set_frame_menubar):
1465 * xfns.c (Fx_show_tip) [USE_GTK]:
1466 Use bool for boolean.
1467 * gtkutil.c (xg_update_frame_menubar):
1468 * xmenu.c (update_frame_menubar):
1469 Return void, not int, since caller ignores return value.
1470 * gtkutil.c (xg_change_toolbar_position):
1473 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
1475 * makefile.w32-in (BLOCKINPUT_H): Remove.

1492 2012-09-23 Eli Zaretskii <eliz@gnu.org>
1494 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
1495 fatal_error_backtrace.
1497 * w32proc.c (sys_kill): Undo last change: don't do anything when
1498 invoked to deliver SIGABRT to our own process. This is now
1499 handled by emacs_raise.
1501 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
1503 * w32term.c (w32_read_socket): Remove leftover reference to
1504 interrupt_input_pending.
1506 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
1508 Do not use SA_NODEFER.
1509 Problem reported by Dani Moncayo in
1510 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
1512 * sysdep.c (emacs_abort): Do not reset signal handler.
1513 * emacs.c (terminate_due_to_signal): Reset signal handler here.
1514 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
1515 wanted even on POSIXish hosts, and it doesn't work on Windows.
1517 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
1519 * xterm.c (x_term_init): Call fixup_locale before and after calling
1520 gtk_init (Bug#12392).
1522 2012-09-23 Chong Yidong <cyd@gnu.org>
1524 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
1525 Vdynamic_library_alist.
1527 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
1528 (Fgnutls_available_p): Caller changed.
1530 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
1531 (Flibxml_parse_xml_region): Likewise.
1533 * dispextern.h (struct image_type): Remove arg from init function.
1535 * image.c (Finit_image_library, lookup_image_type)
1536 (define_image_type): Remove now-unneeded second arg.
1537 (init_xpm_functions, init_png_functions, init_jpeg_functions)
1538 (init_tiff_functions, init_gif_functions, init_svg_functions):
1539 Arglist and w32_delayed_load calling convention changed.
1540 (gs_type): Remove init_gs_functions; there is no such function.
1541 (valid_image_p, make_image): Fix caller to lookup_image_type.
1543 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
1545 Simplify and avoid signal-handling races (Bug#12471).
1547 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
1548 Avoid recursive loop if there's a fatal error in the function itself.
1549 * atimer.c (pending_atimers):
1550 * blockinput.h: Don't include "atimer.h"; no longer needed.
1551 (interrupt_input_pending): Remove. All uses removed.
1552 pending_signals now counts both atimers and ordinary interrupts.
1553 This is less racy than having three separate pending-signal flags.
1554 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
1556 Rename from their upper-case counterparts BLOCK_INPUT,
1557 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
1558 INPUT_BLOCKED_P, and turn into functions. All uses changed.
1559 This makes it easier to access volatile variables more accurately.
1560 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
1561 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
1562 that's more reliable if the code is buggy and sets
1563 interrupt_input_blocked to a negative value. All uses changed.
1564 * atimer.c (deliver_alarm_signal):
1565 Remove. No need to deliver this to the parent; any thread can
1566 handle this signal now. All uses replaced by underlying handler.
1567 * atimer.c (turn_on_atimers):
1568 * dispnew.c (handle_window_change_signal):
1569 * emacs.c (handle_danger_signal):
1570 * keyboard.c (kbd_buffer_get_event):
1571 Don't reestablish signal handler; not needed with sigaction.
1572 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
1574 Rework to avoid unnecessary accesses to volatile variables.
1575 (UNBLOCK_INPUT_TO): Now a function.
1576 (totally_unblock_input, unblock_input): New decls.
1577 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
1578 (init_data): Remove. Necessary stuff now done in init_signal.
1579 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
1580 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
1581 (fatal_error_code): Remove; no longer needed.
1582 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
1583 it doesn't always backtrace. All uses changed. No need to reset
1584 signal to default, since sigaction and/or die does that for us now.
1585 Use emacs_raise (FOO), not kill (getpid (), FOO).
1586 (main): Check more-accurately whether we're dumping.
1587 Move fatal-error setup to sysdep.c
1588 * floatfns.c: Do not include "syssignal.h"; no longer needed.
1589 * gtkutil.c (xg_get_file_name, xg_get_font):
1590 Remove no-longer-needed signal-mask manipulation.
1591 * keyboard.c, process.c (POLL_FOR_INPUT):
1592 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
1593 * keyboard.c (read_avail_input): Remove.
1594 All uses replaced by gobble_input.
1595 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
1596 (kbd_buffer_store_event_hold, gobble_input):
1597 (record_asynch_buffer_change) [USABLE_SIGIO]:
1598 (store_user_signal_events):
1599 No need to mess with signal mask.
1600 (gobble_input): If blocking input and there are terminals, simply
1601 set pending_signals to 1 and return. All hooks changed to not
1602 worry about whether input is blocked.
1603 (process_pending_signals): Clear pending_signals before processing
1604 them, in case a signal comes in while we're processing.
1605 By convention callers now test pending_signals before calling us.
1606 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
1607 New functions, to support changes to blockinput.h.
1608 (handle_input_available_signal): Now extern.
1609 (reinvoke_input_signal): Remove. All uses replaced by
1611 (quit_count): Now volatile, since a signal handler uses it.
1612 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
1613 All callers changed. Block SIGINT only if not already blocked.
1614 Clear sigmask reliably, even if Fsignal returns, which it can.
1615 Omit unnecessary accesses to volatile var.
1616 (quit_throw_to_read_char): No need to restore sigmask.
1617 * keyboard.c (gobble_input, handle_user_signal):
1618 * process.c (wait_reading_process_output):
1619 Call signal-handling code rather than killing ourselves.
1620 * lisp.h: Include <float.h>, for...
1621 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
1622 (pending_signals): Now volatile.
1623 (syms_of_data): Now const if IEEE floating point.
1624 (handle_input_available_signal) [USABLE_SIGIO]:
1625 (terminate_due_to_signal, record_child_status_change): New decls.
1626 * process.c (create_process): Avoid disaster if memory is exhausted
1627 while we're processing a vfork, by tightening the critical section
1629 (send_process_frame, process_sent_to, handle_pipe_signal)
1630 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
1632 (send_process): No need for setjmp/longjmp any more, since the
1633 SIGPIPE stuff is now gone. Instead, report an error if errno
1635 (record_child_status_change): Now extern. PID and W are now args.
1636 Return void, not bool. All callers changed.
1637 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
1638 Remove. All uses removed. This bug should be fixed now in a
1640 (wait_for_termination_1): Use waitpid rather than sigsuspend,
1641 and record the child status change directly. This avoids the
1642 need to futz with the signal mask.
1643 (process_fatal_action): Move here from emacs.c.
1644 (emacs_sigaction_flags): New function, containing
1645 much of what used to be in emacs_sigaction_init.
1646 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
1647 caught by emacs, to make races less likely.
1648 (deliver_process_signal): Rename from handle_on_main_thread.
1650 (BACKTRACE_LIMIT_MAX): Now at top level.
1651 (thread_backtrace_buffer, threadback_backtrace_pointers):
1653 (deliver_thread_signal, deliver_fatal_thread_signal):
1654 New functions, for more-accurate delivery of thread-specific signals.
1655 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
1656 (deliver_arith_signal): Handle in this thread, not
1657 in the main thread, since it's triggered by this thread.
1658 (maybe_fatal_sig): New function.
1659 (init_signals): New arg DUMPING so that we can be more accurate
1660 about whether we're dumping. Caller changed.
1661 Treat thread-specific signals differently from process-general signals.
1662 Block all signals while handling fatal error; that's safer.
1663 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
1665 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
1666 Ignore SIGPIPE unless batch.
1667 (emacs_backtrace): Output backtrace for the appropriate thread,
1668 which is not necessarily the main thread.
1669 * syssignal.h: Include <stdbool.h>.
1670 (emacs_raise): New macro.
1671 * xterm.c (x_connection_signal): Remove; no longer needed
1672 now that we use sigaction.
1673 (x_connection_closed): No need to mess with sigmask now.
1674 (x_initialize): No need to reset SIGPIPE handler here, since
1675 init_signals does this for us now.
1677 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
1679 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
1680 background rect may be larger (Bug#12245).
1682 2012-09-23 Chong Yidong <cyd@gnu.org>
1684 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
1686 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
1688 * .gdbinit: Just stop at fatal_error_backtrace.
1689 See Stefan Monnier's request in
1690 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
1691 Remove no-longer-used query of system type.
1693 2012-09-22 Chong Yidong <cyd@gnu.org>
1695 * search.c (Freplace_match): Doc fix (Bug#12325).
1697 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
1699 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
1700 (Fline_end_position): Doc fix.
1702 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
1704 2012-09-22 Chong Yidong <cyd@gnu.org>
1706 * dispextern.h (struct image_type): Add new slot, storing a type
1707 initialization function.
1709 * image.c (define_image_type): Call the image initializer function
1710 if it is defined. Arguments and return value changed.
1711 (valid_image_p, make_image): Callers changed.
1712 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
1713 (gif_type, imagemagick_type, svg_type, gs_type):
1714 Add initialization functions.
1715 (Finit_image_library): Call lookup_image_type.
1716 (CHECK_LIB_AVAILABLE): Macro deleted.
1717 (lookup_image_type): Call define_image_type here, rather than via
1718 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
1719 (syms_of_image): Move define_image_type calls for xbm_type and
1720 pbm_type to lookup_image_type.
1722 2012-09-22 Eli Zaretskii <eliz@gnu.org>
1724 * keyboard.c (timer_check_2): Move calculation of 'timers' and
1725 'idle_timers' from here ...
1726 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
1727 lists, to avoid infloops when the timer does something stupid,
1728 like reinvoke itself with the same or smaller time-out.
1731 2012-09-22 Martin Rudalics <rudalics@gmx.at>
1733 * window.c (Fsplit_window_internal): Handle only Qt value of
1734 Vwindow_combination_limit separately.
1735 (Qtemp_buffer_resize): New symbol.
1736 (Vwindow_combination_limit): New default value.
1739 2012-09-22 Eli Zaretskii <eliz@gnu.org>
1741 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
1742 the new overlay string. (Bug#10159)
1744 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
1746 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
1747 or that fprintf is async-signal-safe. POSIX doesn't require
1750 2012-09-22 Chong Yidong <cyd@gnu.org>
1752 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
1755 2012-09-22 Kenichi Handa <handa@gnu.org>
1757 * composite.c (composition_reseat_it): Handle the case that a
1758 grapheme cluster is not covered by a single font (Bug#12352).
1760 2012-09-21 Chong Yidong <cyd@gnu.org>
1762 * image.c (define_image_type): Avoid adding duplicate types to
1763 image_types (Bug#12463). Suggested by Jörg Walter.
1765 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1767 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
1768 (print_load_command_name): Add case LC_DATA_IN_CODE.
1769 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
1771 2012-09-21 Glenn Morris <rgm@gnu.org>
1773 * eval.c (Frun_hook_with_args_until_success)
1774 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
1776 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
1778 * fileio.c (Ffile_selinux_context): Only call freecon when
1779 lgetfilecon succeeded.
1780 (Fset_file_selinux_context): Likewise. (Bug#12444)
1782 2012-09-21 Eli Zaretskii <eliz@gnu.org>
1784 * xdisp.c (try_window_reusing_current_matrix): Under bidi
1785 reordering, locate the cursor by calling set_cursor_from_row; if
1786 that fails, clear the desired glyph matrix before returning a
1787 failure indication to the caller. Fixes leaving garbled display
1788 when fast scrolling with a down-key. (Bug#12403)
1789 (compute_stop_pos_backwards): Fix a typo that caused crashes while
1790 scrolling through multibyte text.
1792 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
1794 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
1795 calling mark_vectorlike since that's the one that marks the window.
1796 (mark_discard_killed_buffers): Mark the final cdr.
1797 * window.h (struct window): Move prev/next_buffers to the
1798 non-standard fields.
1799 * window.c (make_window): Initialize prev/next_buffers manually.
1801 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
1803 Omit unused arg EXPECTED from socket hooks.
1804 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
1805 * nsterm.m (ns_term_init):
1806 * termhooks.h (struct terminal.read_socket_hook):
1807 * w32inevt.c (w32_console_read_socket):
1808 * w32term.c (w32_read_socket):
1809 * xterm.c (XTread_socket):
1810 Omit unused arg EXPECTED. All callers changed.
1811 (store_user_signal_events): Return void, not int, since callers no
1812 longer care about the return value. All uses changed.
1814 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
1816 * w32gui.h (XParseGeometry): Do not declare.
1818 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
1820 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
1821 Ignore 'expected'. See Eli Zaretskii in
1822 <http://bugs.gnu.org/12471#8> (last line).
1824 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
1825 (XParseGeometry): Now static. Substitute extremal values for
1826 values that are out of range.
1828 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
1830 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
1832 * nsfns.m (XParseGeometry): Remove.
1833 (Fx_create_frame): Call x_set_offset to correctly interpret
1834 top_pos in geometry.
1836 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
1837 (Fx_parse_geometry): If there is a space in string, call
1838 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
1840 2012-09-17 Eli Zaretskii <eliz@gnu.org>
1842 * search.c (scan_buffer): Use character positions in calls to
1843 region_cache_forward and region_cache_backward, not byte
1844 positions. (Bug#12196)
1846 * w32term.c (w32_read_socket): Set pending_signals to 1, like
1847 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
1849 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
1850 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
1851 emacs_blocked_malloc, now deleted.
1853 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
1855 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
1856 The workaround was for improving performance on Solaris 2.4, but
1857 is getting in the way now. Emacs will still work if someone is
1858 still running Solaris 2.4 in a museum somewhere; Sun dropped
1859 support for Solaris 2.4 in 2003.
1860 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
1861 * process.c (create_process) [HAVE_WORKING_VFORK]:
1862 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
1863 since Emacs no longer uses vfork on that platform.

1867 * emacs.c: Use COPYRIGHT.

1871 Remove configure's --without-sync-input option (Bug#12450).
1872 When auditing signal-handling in preparation for cleaning it up,
1873 I found that SYNC_INPUT has race conditions and would be a real
1874 pain to fix. Since it's an undocumented and deprecated
1875 configure-time option, now seems like a good time to remove it.
1876 Also see <http://bugs.gnu.org/11080#16>.
1877 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
1878 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
1879 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
1880 (malloc_hysteresis):
1881 (check_depth) [XMALLOC_OVERRUN_CHECK]:
1882 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
1883 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
1884 (dont_register_blocks, bytes_used_when_reconsidered)
1885 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
1886 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
1887 [!SYSTEM_MALLOC && !SYNC_INPUT]:
1888 Remove. All uses removed.
1889 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
1890 implementation, one that depends on whether the new macro
1891 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
1893 * atimer.c (run_timers, handle_alarm_signal):
1894 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
1895 (handle_async_input, process_pending_signals)
1896 (handle_input_available_signal, init_keyboard):
1897 * nsterm.m (ns_read_socket):
1898 * process.c (wait_reading_process_output):
1899 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
1900 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
1902 * xterm.c (XTread_socket):
1904 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
1905 * eval.c (handling_signal): Remove. All uses removed.
1906 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
1907 All uses replaced with the SYNC_INPUT version.
1908 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
1910 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
1913 * font.c (Ffont_shape_gstring): Remove unused local.
1915 2012-09-16 Glenn Morris <rgm@gnu.org>
1917 * Makefile.in (clean): No longer run nextstep's clean.
1919 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
1921 (ns-app): Move here from ns.mk, and simplify.
1922 (clean): Simplify nextstep entry.
1923 * ns.mk: Remove file.
1925 2012-09-17 Kenichi Handa <handa@gnu.org>
1927 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
1928 not covert the last few charactes.
1930 2012-09-16 Kenichi Handa <handa@gnu.org>
1932 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
1933 here, but just check the validity of glyphs in the glyph-string.
1935 2012-09-16 Martin Rudalics <rudalics@gmx.at>
1937 * window.c (Fwindow_parameter, Fset_window_parameter):
1938 Accept any window as argument (Bug#12452).
1940 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
1942 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
1943 to ns_term_init to avoid memory leak.
1945 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
1946 explicit retain/release.
1947 (ns_term_init): Only allow one display. Initialize outerpool and
1950 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
1952 Port _setjmp fix to POSIXish hosts as well as Microsoft.
1953 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
1954 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
1955 the Microsoft problem in a different way, by altering ../nt/config.nt.
1957 2012-09-15 Eli Zaretskii <eliz@gnu.org>
1972 * w16select.c: Remove inclusion of setjmp.h, as it is now included
1973 by lisp.h. This completes removal of setjmp.h inclusion
1974 erroneously announced in the previous commit. (Bug#12446)
1976 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
1979 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
1980 not defined as a macro. The latter happens on MS-Windows.
1983 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
1985 Port better to POSIX hosts lacking _setjmp (Bug#12446).
1986 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
1987 Some instances of '#include <setjmp.h>' removed, if the
1988 only reason for the instance was because "lisp.h" was included.
1989 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
1990 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
1991 and _longjmp with the new symbols. Emacs already uses _setjmp if
1992 available, so this change affects only POSIXish hosts that have
1993 sigsetjmp but not _setjmp, such as some versions of Solaris and
1994 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
1995 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
1996 (png_load_body) [HAVE_PNG]:
1997 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
1998 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
1999 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
2000 since PNG requires jmp_buf. This is the only exception to the
2001 general rule that we now use sys_setjmp and sys_longjmp.
2002 This exception is OK since this code does not change the signal
2003 mask or longjmp out of a signal handler.
2005 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
2007 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
2008 Include "syssignal.h", for 'main_thread'.
2010 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
2012 Avoid out-of-range marker position (Bug#12426).
2013 * insdel.c (replace_range, replace_range_2):
2014 Adjust markers before overlays, as suggested by comments.
2015 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
2016 Remove redundant check before calling offset_intervals.
2018 2012-09-14 Martin Rudalics <rudalics@gmx.at>
2020 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
2021 current buffer (Bug#12387).
2023 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
2025 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
2027 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
2029 Use a more backwards-compatible timer format (Bug#12430).
2030 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
2031 vector element, not from the 4th, since PSECS is now at the end.
2032 (Fcurrent_idle_time): Doc fix.
2034 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
2036 Function to mark objects and remove killed buffers at once.
2037 * alloc.c (discard_killed_buffers): Rename to ...
2038 (mark_discard_killed buffers) ... new name. Add marking
2039 of remaining objects. Fix comment. Adjust users.
2040 (mark_object): Do not touch frame buffer lists here.
2041 * frame.c (delete_frame): Reset frame buffer lists here.
2043 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
2045 Better workaround for GNOME bug when --enable-gcc-warnings.
2046 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
2047 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
2048 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
2050 Simplify SIGIO usage (Bug#12408).
2051 The code that dealt with SIGIO was crufty and confusing, e.g., it
2052 played tricks like "#undef SIGIO" but these tricks were not used
2053 consistently. Simplify mostly by not #undeffing standard symbols,
2054 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
2055 or not as we please) rather than "defined SIGIO" (standard symbol
2056 that we probably shouldn't #undef).
2057 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
2058 Modules that need it can include it.
2059 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
2060 * dispextern.h (ignore_sigio): New decl.
2061 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
2062 unconditionally, since it's now a no-op if !USABLE_SIGIO.
2063 * emacs.c (shut_down_emacs):
2064 * keyboard.c (kbd_buffer_store_event_hold):
2065 Use ignore_sigio rather than invoking 'signal' directly.
2066 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
2068 (FIONREAD, SIGIO): Do not #undef.
2069 (tty_read_avail_input): Use #error rather than a syntax error.
2070 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
2071 for I_PIPE, used by SETUP_SLAVE_PTY.
2072 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
2073 * sysdep.c (croak): Remove; no longer needed. This bit of
2074 temporary code, with Fred N. Fish's comment that it's temporary,
2075 has been in Emacs since at least 1992!
2076 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
2077 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
2078 * syssignal.h (croak): Remove decl.
2079 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
2080 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
2081 now that we're termios-only.
2082 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
2083 * term.c (dissociate_if_controlling_tty): Use #error rather than
2086 Work around GCC and GNOME bugs when --enable-gcc-warnings.
2087 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
2088 to work around GNOME bug 683906.
2089 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
2090 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
2091 This works around GCC bug 54561.
2093 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
2095 More fixes for 'volatile' and setjmp/longjmp.
2096 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
2097 * image.c (struct png_load_context) [HAVE_PNG]: New type.
2098 (png_load_body) [HAVE_PNG]:
2099 (jpeg_load_body) [HAVE_JPEG]:
2100 New function, with most of the old parent function's body.
2101 (png_load) [HAVE_PNG]:
2102 (jpeg_load) [HAVE_JPEG]:
2103 Invoke the new function, to avoid longjmp munging our locals.
2104 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
2105 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
2106 longjmp is passed 2, as the C standard doesn't guarantee this.
2107 Instead, store the failure code into mgr->failure_code.
2109 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
2111 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
2112 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
2113 (syms_of_keyboard): Remove support for unread-command-char.
2115 2012-09-12 Eli Zaretskii <eliz@gnu.org>
2117 * w32proc.c (sys_kill): If PID is our process ID and the signal is
2118 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
2119 violation. (Bug#12426)
2121 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
2123 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
2125 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
2127 * eval.c: Add `inhibit-debugger'.
2128 (Qinhibit_debugger): New symbol.
2129 (call_debugger): Bind it instead of Qdebug_on_error.
2130 (maybe_call_debugger): Test Vinhibit_debugger.
2131 (syms_of_eval): Define inhibit-debugger.
2132 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
2133 (syms_of_xdisp): Remove inhibit-debug-on-message.
2135 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
2137 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
2138 If a nonvolatile local variable is written before a _longjmp to
2139 the frame containing the variable, and is read after the _longjmp,
2140 the value read is indeterminate. Some local variables of type
2141 'struct handler' and 'struct catchtag' are used in this way, so
2142 mark each of their slots as volatile if the slot can be set before
2143 _longjmp and read afterwards.
2144 * lisp.h (struct handler): var and chosen_clause are now volatile.
2145 (struct catchtag): val, next, and pdlcount are now volatile.
2147 * bidi.c (bidi_push_it, bidi_pop_it):
2148 * fns.c (copy_hash_table):
2149 * image.c (define_image_type):
2150 * keyboard.c (kbd_buffer_store_event_hold):
2151 * process.c (Fprocess_send_eof):
2152 * xfaces.c (x_create_gc) [HAVE_NS]:
2153 * xgselect.c (xg_select):
2154 Prefer assignment to memcpy when either will do.
2156 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
2157 Use pointer-to-a-pointer to simplify and avoid a NILP check each
2158 time an item is removed. No need to mark this function 'inline';
2159 the compiler knows better than we do.
2161 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
2163 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
2164 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
2165 to change_frame_size (Bug#12388).
2166 (windowDidResize:): Pass YES to updateFrameSize.
2168 * nsterm.h: Add delay parameter to updateFrameSize.
2170 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
2172 Discard killed buffers from deleted window and frame objects.
2173 This reduces an amount of references to killed buffers and
2174 helps GC to reclaim them faster.
2175 * alloc.c (discard_killed_buffers): New function.
2176 (mark_object): Use it for deleted windows and frames.
2177 (mark_object): If symbol's value is set up for a killed buffer
2178 or deleted frame, restore its global binding.
2179 * data.c (swap_in_global_binding): Add GC notice.
2180 (swap_in_symval_forwarding): Use convenient set_blv_where.
2181 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
2182 * window.h: ... to here.
2184 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
2186 Convenient macro to check whether the buffer is live.
2187 * buffer.h (BUFFER_LIVE_P): New macro.
2188 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
2189 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
2191 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2193 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
2194 composition cases (Bug#12364).
2196 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
2197 overhang of succeeding glyphs overlapping box cursor.
2199 * w32term.c (x_draw_glyph_string): Likewise.
2201 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
2203 Simplify, document, and port floating-point (Bug#12381).
2204 The porting part of this patch fixes bugs on non-IEEE platforms
2205 with frexp, ldexp, logb.
2206 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
2208 * floatfns.c: Simplify discussion of functions that Emacs doesn't
2209 support, by removing commented-out code and briefly listing the
2210 C89 functions excluded. The commented-out stuff was confusing
2211 maintenance, e.g., we thought we needed cbrt but it was commented out.
2212 (logb): Remove decl; no longer needed.
2213 (isfinite): New macro, if not already supplied.
2214 (isnan): Don't replace any existing macro.
2215 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
2216 are present on all C89 platforms.
2217 (Ffrexp): Do not special-case zero, as frexp does the right thing
2219 (Flogb): Do not use logb, as it doesn't have the desired meaning
2220 on hosts that use non-base-2 floating point. Instead, stick with
2221 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
2222 frexp, to avoid getting an unspecified result.
2224 * xdisp.c (Qinhibit_debug_on_message): Now static.
2226 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
2228 * nsterm.m (ns_update_begin): Set clip path to whole view by using
2229 NSBezierPath (Bug#12131).
2231 2012-09-10 Chong Yidong <cyd@gnu.org>
2233 * fns.c (Fdelq, Fdelete): Doc fix.
2235 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
2237 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
2238 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
2240 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
2242 * lisp.h (make_lisp_ptr): New macro to replace XSET.
2243 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
2246 2012-09-09 Eli Zaretskii <eliz@gnu.org>
2248 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
2249 left fringe if the window has a left margin. This avoids leaving
2250 traces of the cursor because its leftmost pixel is not drawn over.
2252 * dispnew.c (update_window_line): When the left margin area of a
2253 screen line is updated, set the redraw_fringe_bitmaps_p flag of
2254 that screen line. (Bug#12277)
2256 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
2258 Assume C89 or later for math functions (Bug#12381).
2259 This simplifies the code, and makes it a bit smaller and faster,
2260 and (most important) makes it easier to clean up signal handling
2261 since we can stop worring about floating-point exceptions in
2262 library code. That was a problem before C89, but the problem
2263 went away many years ago on all practical Emacs targets.
2264 * data.c, image.c, lread.c, print.c:
2265 Don't include <math.h>; no longer needed.
2266 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
2267 might be autoconfigured, as that never happens.
2269 * doprnt.c (DBL_MAX_10_EXP):
2270 * print.c (DBL_DIG):
2271 Remove. C89 or later always defines these.
2272 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
2273 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
2274 (arith_error, domain_error, domain_error2):
2275 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
2276 no longer needed -- we simply return what C returns. All uses removed.
2277 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
2279 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
2280 Remove. All uses expanded, as these macros are no longer used
2281 more than once and are now more trouble than they're worth.
2282 (Ftan): Use tan, not sin / cos.
2283 (Flogb): Assume C89 frexp.
2284 (fmod_float): Assume C89 fmod.
2285 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
2286 (init_floatfns): Remove. All uses removed.
2288 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
2290 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
2291 compositeToPoint for OSX < 10.6 (Bug#12390).
2293 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
2295 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
2296 This produces more-accurate results.
2298 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
2300 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
2301 changes (Bug#12088).
2303 2012-09-08 Chong Yidong <cyd@gnu.org>
2305 * syntax.c (Fstring_to_syntax): Doc fix.
2307 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
2309 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
2310 in the internal border.
2311 (x_set_window_size): Remove static variables and their usage.
2312 (ns_redraw_scroll_bars): Fix NSTRACE arg.
2313 (ns_after_update_window_line, ns_draw_fringe_bitmap):
2314 Remove fringe/internal border adjustment (Bug#11052).
2315 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
2316 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
2317 (ns_fix_rect_ibw): Remove.
2318 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
2319 (ns_dumpglyphs_box_or_relief): Ditto.
2320 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
2322 (ns_dumpglyphs_image): Ditto.
2323 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
2325 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
2326 their usage. Add fringe_extended_p and its use as in other terms.
2327 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
2328 scroll bar was removed.
2329 (updateFrameSize): New function.
2330 (windowDidResize): Move code to updateFrameSize and call it.
2332 * nsterm.h (EmacsView): Add updateFrameSize.
2334 2012-09-07 Chong Yidong <cyd@gnu.org>
2336 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
2338 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
2340 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
2342 More signal-handler cleanup (Bug#12327).
2343 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
2344 Problem introduced when merging patches. Noted by Eli Zaretskii in
2345 <http://bugs.gnu.org/12327#67>.
2346 * floatfns.c: Comment fix.
2347 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
2348 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
2349 and anyway the declaration is harmless even if SIGDANGER is not defined.
2350 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
2351 defined BROKEN_FIONREAD). systty.h formerly did this, but other
2352 source files not surprisingly expected syssignal.h to define, or
2353 not define, SIGIO, and it's cleaner to do it that way, for consistency.
2354 Include <sys/ioctl.h>, for FIONREAD.
2355 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
2356 This eliminates a problem whereby other files mysteriously had
2357 to include "syssignal.h" before including "systty.h" if they
2358 wanted to use "#ifdef SIGIO".
2360 2012-09-07 Eli Zaretskii <eliz@gnu.org>
2362 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
2364 * w32.c (sigemptyset): Empty the set.
2365 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
2367 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
2369 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
2371 * alloc.c (mark_buffer): Revert unsafe marking optimization.
2372 (mark_object): Likewise for frame objects.
2374 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
2376 * syssignal.h (handle_on_main_thread): Always declare,
2377 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
2378 This ports to platforms without HAVE_PTHREAD.
2380 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
2382 Signal-handler cleanup (Bug#12327).
2383 Emacs's signal handlers were written in the old 4.2BSD style with
2384 sigblock and sigmask and so forth, and this led to some
2385 inefficiencies and confusion. Rewrite these to use
2386 pthread_sigmask etc. without copying signal sets around. Also,
2387 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
2388 'signal', and instead use functions that do not attempt to take
2389 over the system name space. This patch causes Emacs's text
2390 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
2391 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
2392 Do not include <signal.h> or "syssignal.h", as these
2393 modules do not use signals.
2394 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
2395 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
2396 Do not include <signal.h>, as "syssignal.h" does that for us now.
2397 * atimer.c (sigmask_atimers): New function.
2398 (block_atimers, unblock_atimers): New functions,
2399 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
2401 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
2402 no longer needed here.
2403 * emacs.c (main): Inspect existing signal handler with sigaction,
2404 so that there's no need to block and unblock SIGHUP.
2405 * sysdep.c (struct save_signal): New member 'action', replacing
2406 old member 'handler'.
2407 (save_signal_handlers, restore_signal_handlers):
2408 Use sigaction instead of 'signal' to save and restore.
2409 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
2410 New function. All users of 'signal' modified to use set_sighandler
2411 if they're writeonly, and to use sys_signal if they're read+write.
2412 (emacs_sigaction_init, forwarded_signal): New functions.
2413 (sys_signal): Remove. All uses replaced by calls to sigaction
2414 and emacs_sigaction_init, or by direct calls to 'signal'.
2415 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
2416 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
2417 all uses replaced by pthread_sigmask etc. calls.
2418 * syssignal.h: Include <signal.h>.
2419 (emacs_sigaction_init, forwarded_signal): New decls.
2420 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
2421 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
2422 (sigmask, sys_sigmask): Remove; no longer needed.
2423 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
2424 (sigblock, sigunblock, sigfree):
2425 (sigsetmask) [!defined sigsetmask]:
2426 Remove. All uses replaced by pthread_sigmask.
2427 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
2428 no longer need to be replaced, and its typical old uses
2429 are now done via emacs_sigaction_init and sigaction.
2430 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
2431 (sys_sigdel): Remove; unused.
2432 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
2434 2012-09-06 Eli Zaretskii <eliz@gnu.org>
2436 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
2437 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
2439 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
2441 Explicitly mark buffer_defaults and buffer_local_symbols.
2442 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
2443 mark_local_symbols here.
2444 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
2445 since special buffers aren't marked here any more.
2446 (allocate_buffer): Chain new buffer with all_buffers here...
2447 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
2449 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
2450 (syms_of_buffer): Remove staticpro of the above.
2451 (init_buffer_once): Set names for buffer_defaults and
2452 buffer_local_symbols.
2454 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
2456 Use bool for booleans in font-related modules.
2457 * font.c (font_intern_prop, font_style_to_value)
2458 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
2459 (generate_otf_features, font_check_otf_features, font_check_otf)
2460 (font_match_p, font_list_entities, font_at):
2461 * fontset.c (fontset_id_valid_p, reorder_font_vector
2462 (fontset_find_font, Fset_fontset_font)
2463 (face_suitable_for_char_p) [0]:
2464 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
2465 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
2466 (m17n_flt_initialized, ftfont_shape_by_flt):
2467 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
2468 * nsfont.m (nsfont_draw):
2469 * w32font.c (w32font_draw):
2470 * w32term.c (x_draw_glyphless_glyph_string_foreground):
2471 Use bool for booleans.
2472 * font.h: Adjust to above API changes.
2473 (struct font, struct font_driver, struct font_driver_list):
2474 Use bool for booleans.
2475 (struct font): Remove useless member encoding_type.
2477 * fontset.c, xftfont.c: Omit unnecessary static decls.
2479 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
2481 * alloc.c (mark_object): Revert window marking code
2482 since it's unsafe for the Fset_window_configuration.
2484 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
2486 Fix race conditions with signal handlers and errno (Bug#12327).
2487 Be more systematic about preserving errno whenever a signal
2488 handler returns, even if it's not in the main thread. Do this by
2489 renaming signal handlers to distinguish between signal delivery
2490 and signal handling. All uses changed.
2491 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
2492 * data.c (deliver_arith_signal): Rename from arith_error.
2493 * dispnew.c (deliver_window_change_signal): Rename from
2494 window_change_signal.
2495 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
2496 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
2497 * keyboard.c (deliver_input_available_signal): Rename from
2498 input_available_signal.
2499 (deliver_user_signal): Rename from handle_user_signal.
2500 (deliver_interrupt_signal): Rename from interrupt_signal.
2501 * process.c (deliver_pipe_signal): Rename from send_process_trap.
2502 (deliver_child_signal): Rename from sigchld_handler.
2503 * atimer.c (handle_alarm_signal):
2504 * data.c (handle_arith_signal):
2505 * dispnew.c (handle_window_change_signal):
2506 * emacs.c (handle_fatal_signal, handle_danger_signal):
2507 * keyboard.c (handle_input_available_signal):
2508 * keyboard.c (handle_user_signal, handle_interrupt_signal):
2509 * process.c (handle_pipe_signal, handle_child_signal):
2510 New functions, with the actual signal-handling code taken from the
2511 original respective signal handlers, sans the sporadic attempts to
2512 preserve errno, since that's now done by handle_on_main_thread.
2513 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
2514 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
2515 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
2517 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
2518 Move initialization of main_thread to sysdep.c's init_signals.
2519 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
2520 our usage, and simplifies the mainline code.
2521 (record_child_status_change): New static function, as a helper
2522 for handle_child_signal, and with most of the old child handler's
2524 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
2525 (handle_child_signal): Use the above.
2526 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
2527 Moved here from emacs.c.
2528 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
2529 code moved here from emacs.c's main function.
2530 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
2531 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
2532 This lets callers save and restore errno properly.
2534 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
2536 Remove redundant or unused things here and there.
2537 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
2538 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
2539 * editfns.c (Fcompare_buffer_substrings): Likewise.
2540 * frame.h (struct terminal, struct font_driver_list):
2541 Remove redundant declarations.
2542 * window.h (Qleft, Qright): Likewise.
2544 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
2546 Do not mark objects from deleted buffers, windows and frames.
2547 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
2548 (mark_object): Likewise for windows and frames.
2550 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
2552 * alloc.c (valid_lisp_object_p): Treat killed buffers,
2553 buffer_defaults and buffer_local_symbols as valid objects.
2554 Return special value to denote them.
2556 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
2558 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
2559 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
2560 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
2561 (file_name_absolute_p, Fsubstitute_in_file_name):
2562 (check_executable, check_writable, Ffile_accessible_directory_p)
2563 (Fset_file_selinux_context, Fdefault_file_modes)
2564 (Finsert_file_contents, choose_write_coding_system)
2565 (Fwrite_region, build_annotations, a_write, e_write)
2567 * filelock.c (boot_time_initialized, get_boot_time)
2568 (get_boot_time_1, lock_file_1, within_one_second):
2569 * floatfns.c (in_float):
2570 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
2571 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
2572 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
2573 * lisp.h (struct Lisp_Hash_Table.cmpfn):
2574 * window.c (compare_window_configurations):
2575 Use bool for booleans.
2576 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
2577 (Fdefault_file_modes): Now mode_t, not int, for modes.
2578 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
2579 (internal_delete_file): Now returns void, not a (boolean) int,
2580 since nobody was looking at the return value.
2581 * lisp.h, window.h: Adjust to above API changes.
2583 * xdisp.c (set_message): Simplify and reindent last change.
2585 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
2587 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
2589 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
2591 * eval.c (call_debugger): Make the function non-static so that we
2592 can call it from set_message.
2594 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
2595 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
2597 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
2599 Give more-useful info on a fatal error (Bug#12328).
2600 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
2601 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
2602 of doing the work ourselves.
2603 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
2604 do most of the work.
2605 (fatal_error_backtrace): New function, taken from the guts
2606 of the old fatal_error_signal, but with a new option to output
2608 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
2609 info about the signal than just its number.
2610 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
2611 * sysdep.c: Include <execinfo.h>
2612 (emacs_backtrace): New function, taken partly from the previous
2613 code of the 'die' function.
2614 (emacs_abort): Call fatal_error_backtrace rather than abort.
2616 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
2618 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
2619 eager (load-time) macro-expansion.
2620 * lisp.mk (lisp): Add macroexp.
2622 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
2624 Simplify redefinition of 'abort' (Bug#12316).
2625 Do not try to redefine the 'abort' function. Instead, redo
2626 the code so that it calls 'emacs_abort' rather than 'abort'.
2627 This removes the need for the NO_ABORT configure-time macro
2628 and makes it easier to change the abort code to do a backtrace.
2629 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
2630 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
2631 Remove; sysdep.c's emacs_abort now takes its place.
2632 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
2633 'abort' changed to use 'emacs_abort'.
2634 * msdos.c (dos_abort) [defined abort]: Remove; not used.
2635 (abort) [!defined abort]: Rename to ...
2636 (emacs_abort): ... new name.
2637 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
2638 the place of the old 'abort' in emacs.c.
2639 * w32.c, w32fns.c (abort): Do not #undef.
2640 * w32.c (emacs_abort): Rename from w32_abort.
2642 2012-09-04 Eli Zaretskii <eliz@gnu.org>
2644 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
2645 offsets[j].dv, since the y axis of the screen coordinates points
2646 down, while the y axis of the font definition coordinates points
2647 up. This fixes display of Arabic diacritics such as KASRA and
2648 KASRATAN. (Bug#11860)
2650 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
2652 Be more systematic about _setjmp vs setjmp.
2653 * alloc.c (test_setjmp, mark_stack):
2654 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
2655 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
2656 (png_load, my_error_exit, jpeg_load):
2657 * process.c (send_process_trap, send_process):
2658 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
2659 The underscored versions are up to 30x faster on some hosts.
2660 Formerly, the code used setjmp+longjmp sometimes and
2661 _setjmp+_longjmp at other times, with no particular reason to
2662 prefer setjmp+longjmp.
2664 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
2666 Fix minor problem found by static checking.
2667 * buffer.c (Fdelete_all_overlays): Return nil.
2669 2012-09-03 Martin Rudalics <rudalics@gmx.at>
2671 * buffer.c (Fdelete_all_overlays): New function.
2673 2012-09-03 Chong Yidong <cyd@gnu.org>
2675 * gtkutil.c: Add extern decl for Qxft.
2677 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
2679 * emacs.c, eval.c: Use bool for boolean.
2680 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
2681 (malloc_using_checking) [DOUG_LEA_MALLOC]:
2682 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
2683 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
2684 (main, decode_env_path, Fdaemon_initialized):
2685 * eval.c (call_debugger, Finteractive_p, interactive_p):
2686 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
2687 (maybe_call_debugger, Fbacktrace):
2688 * process.c (read_process_output, exec_sentinel):
2689 Use bool for booleans.
2690 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
2691 All callers changed.
2692 * eval.c (interactive_p): Omit always-true boolean argument
2693 EXCLUDE_SUBRS_P. All callers changed.
2694 * dispextern.h, lisp.h: Reflect above API changes.
2695 * firstfile.c (dummy): Use the address of 'main', whose signature
2696 won't change, instead of the address of 'initialize', whose
2697 signature just changed from int to bool.
2698 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
2699 * msdos.c (fatal_error_in_progress): ... from here.
2700 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
2702 (redisplay_internal, unwind_redisplay): Simply clear
2703 REDISPLAYING_P when unwinding, instead of saving its previous,
2704 always-false value and then restoring it.
2706 Clean up some extern decls.
2707 Mostly, this hoists extern decls out of .c files and into .h files.
2708 That way, we're more likely to catch errors if the interfaces change.
2709 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
2710 declare xg_mark_data.
2711 * dispextern.h (x_frame_parm_handlers):
2713 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
2714 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
2715 (Qultra_bold, Qoblique, Qitalic):
2716 Move extern decl here from .c file.
2717 * alloc.c (xg_mark_data) [USE_GTK]:
2719 * eval.c (Qlexical_binding):
2720 * fns.c (time) [!HAVE_UNISTD_H]:
2721 * gtkutil.c (Qxft, Qnormal, Qextra_light, Qlight, Qsemi_light)
2722 (Qsemi_bold, Qbold, Qextra_bold, Qultra_bold, Qoblique, Qitalic):
2723 * image.c (Vlibrary_cache, QCloaded_from) [HAVE_NTGUI]:
2724 * lread.c (Qinternal_interpreter_environment):
2725 * minibuf.c (Qbuffer):
2726 * process.c (QCfamily, QCfilter):
2727 * widget.c (free_frame_faces):
2728 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
2729 * xfont.c (x_clear_errors):
2730 * xterm.c (x_frame_parm_handlers):
2731 Remove now-redundant extern decls.
2732 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
2733 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
2735 * xfaces.c: Remove unnecessary static decls.
2736 * xterm.c (updating_frame): Remove decl of nonexistent object.
2738 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
2739 when building globals.h, as the objects that are not built on

2796 offset adjustment values separately for each cluster. (Bug#11860)
2798 * image.c: Restore mistakenly removed inclusion of w32.h. Without
2799 it, GCC doesn't see prototypes of w32_delayed_load, and complains
2800 about implicit conversions from integer to pointer.

2858 window system declarations.
2860 * frame.h: Move common functions here: set_frame_menubar,
2861 x_set_window_size, x_sync, x_get_focus_frame,

2920 for GCC 4.7.1 x86-64.
2922 2012-08-30 Glenn Morris <rgm@gnu.org>
2924 * lread.c (init_lread): For out-of-tree builds, only add the
2925 source directory's site-lisp dir to the load-path if it exists,
2926 consistent with in-tree builds. (Bug#12302)
2928 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>

3162 It was meant to be temporary and it often doesn't work,
3163 because when IDX has side effects the behavior of IDX==IDX
3164 is undefined. See Stefan Monnier in
3165 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
3167 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)

3176 as that's faster and simpler than static storage. Don't bother
3177 with the g_main_context_query overhead if g_main_context_pending
3178 says no events are pending.
3179 (gfds, gfds_size): Remove these static vars.
3180 (xgselect_initialize): Remove; no longer needed.
3181 All uses and decls removed.

3191 Use bool for booleans, instead of int.
3193 2012-08-25 Eli Zaretskii <eliz@gnu.org>
3195 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
3197 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
3199 On assertion failure, print backtrace if available.
3200 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
3201 (die) [ENABLE_CHECKING]: Print a backtrace if available.
3202 * Makefile.in (LIB_EXECINFO): New macro.
3205 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
3206 * bytecode.c (exec_byte_code):
3207 * callint.c (check_mark, Fcall_interactively):
3208 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
3209 (getenv_internal, sync_process_alive, call_process_exited):
3210 * lisp.h (USE_SAFE_ALLOCA):
3211 Use bool for booleans, instead of int.
3212 * lisp.h, process.h: Adjust prototypes to match above changes.
3213 * callint.c (Fcall_interactively): Don't assume the mark's
3214 offset fits in 'int'.
3216 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
3218 * buffer.c, buffer.h: Use bool for boolean.
3219 * buffer.c (reset_buffer_local_variables)
3220 (buffer_lisp_local_variables, Fset_buffer_modified_p)
3221 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
3222 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
3223 (overlay_touches_p, overlay_strings, Foverlay_put)
3224 (report_overlay_modification, call_overlay_mod_hooks):
3225 (mmap_enlarge, mmap_set_vars):
3226 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
3227 Use bool for booleans, instead of int.
3228 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
3229 since the 1-or-0 return value is always ignored anyway.
3230 (mmap_initialized_p):
3231 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
3232 * buffer.h, lisp.h: Adjust prototypes to match above changes.
3234 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
3236 * bidi.c: Use bool for boolean.
3237 This is a bit more readable, and makes the text segment of bidi.o
3238 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
3239 Presumably it's faster too.
3240 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
3242 (bidi_cache_find_level_change, bidi_cache_iterator_state)
3243 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
3244 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
3245 (bidi_explicit_dir_char, bidi_level_of_next_char)
3246 (bidi_find_other_level_edge, bidi_move_to_visually_next):
3247 Use bool for booleans, instead of int.
3248 * dispextern.h (bidi_init_it, bidi_paragraph_init)
3249 (bidi_unshelve_cache): Adjust decls to match code.
3251 2012-08-23 Martin Rudalics <rudalics@gmx.at>
3253 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
3256 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
3258 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
3259 * atimer.h: Include <stdbool.h>.
3261 2012-08-22 Dan Nicolaescu <dann@gnu.org>
3263 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
3264 compile time tests instead of run time tests on systems that do
3266 (FRAME_MAC_P): Remove leftover from deleted code.
3267 * frame.c (syms_of_frame): Remove leftover from deleted code.
3269 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
3271 * nsterm.m (insertText:): Don't clear modifiers if code is space.
3273 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
3275 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
3276 Otherwise, the compiler complains about (A?B:C) where B is void
3277 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
3278 (fontset_add): Return void, for FONTSET_ADD.
3280 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
3282 * alloc.c: Use bool for booleans.
3283 (gc_in_progress, abort_on_gc)
3284 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
3285 (dont_register_blocks) [GC_MALLOC_CHECK]:
3286 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
3287 (check_string_bytes, make_specified_string, memory_full)
3288 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
3289 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
3290 (mark_stack, valid_pointer_p, make_pure_string)
3291 (Fgarbage_collect, survives_gc_p, gc_sweep):
3292 Use bool for booleans, instead of int.
3293 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
3294 Remove unused local.
3295 * alloc.c (PURE_POINTER_P):
3296 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
3297 * editfns.c (Fformat):
3298 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
3300 * fns.c (sweep_weak_table):
3301 * lisp.h (suppress_checking, push_message, survives_gc_p)
3302 (make_pure_string, gc_in_progress, abort_on_gc):
3303 * lread.c (readchar, read1):
3304 * print.c (Fprin1_to_string):
3305 * xdisp.c (push_message):
3306 Use bool for booleans affected directly or indirectly by
3309 Make recently-introduced setters macros.
3310 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
3311 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
3312 (set_fontset_default, set_fontset_fallback): Rename from their
3313 upper-case counterparts, and make them functions rather than macros.
3314 This is more consistent with the other recently-introduced setters.
3315 These don't need to be inline, since they're local.
3317 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
3319 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
3320 the loop (Bug#12247).
3322 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
3324 * lisp.h (vcopy): Use memcpy rather than our own loop.
3325 This fixes a performance regression introduced by the recent
3326 addition of vcopy. This means 'vcopy' will need to be modified
3327 for a copying collector, but that's OK. Also, tighten the
3328 checking in the assertion.
3330 2012-08-21 Eli Zaretskii <eliz@gnu.org>
3332 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
3333 components for RTL text (Bug#11860). Adjust X-OFFSET of each
3334 non-base glyph for the width of the base character, according to
3335 what x_draw_composite_glyph_string_foreground expects.
3336 Generate WADJUST value according to composition_gstring_width's
3337 expectations, to produce correct width of the composed character.
3338 Reverse the sign of the DU offset produced by ScriptPlace.
3340 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
3342 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
3344 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
3346 Avoid direct writes to contents member of struct Lisp_Vector.
3347 * lisp.h (vcopy): New function to copy data into vector.
3348 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
3349 * fns.c (Ffillarray): Use ASET.
3350 * keyboard.c (timer_check_2): Use AREF and ASET.
3351 (append_tool_bar_item, Frecent_keys): Use vcopy.
3352 * lread.c (read_vector): Use ASET.
3353 * msdos.c (Frecent_doskeys): Use vcopy.
3354 * xface.c (Finternal_copy_lisp_face): Use vcopy.
3355 (Finternal_merge_in_global_face): Use ASET and vcopy.

3361 the position of its buffer's point.
3362 (Fset_window_point): For the selected window always go in its
3363 buffer to the specified position.
3365 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
3367 Setter macros for fontsets.
3368 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
3369 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
3370 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
3373 2012-08-20 Glenn Morris <rgm@gnu.org>
3375 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
3376 Don't assume that `ln -f' works.
3378 2012-08-20 Eli Zaretskii <eliz@gnu.org>
3380 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
3381 and later about non-assignments with no effect. See discussion at
3382 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
3385 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
3387 Inline setter functions for Lisp_Objects slots of struct specbinding.
3388 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
3391 2012-08-20 Martin Rudalics <rudalics@gmx.at>
3393 * window.c (select_window): Always make selected window's buffer
3396 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
3398 Use AREF and ASET for docstrings of category tables.
3399 * category.h (CATEGORY_DOCSTRING): Use AREF.
3400 (SET_CATEGORY_DOCSTRING): Use ASET.
3401 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
3403 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
3405 Inline setter functions for hash table members.
3406 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
3407 (set_hash_hash, set_hash_index): Rename with _slot suffix.
3408 (set_hash_key_and_value, set_hash_index, set_hash_next)
3409 (set_hash_hash): New functions.
3410 * charset.c, fns.c: Adjust users.
3412 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
3414 Inline getter and setter functions for per-buffer values.
3415 * buffer.h (per_buffer_default, set_per_buffer_default)
3416 (per_buffer_value, set_per_buffer_value): New functions.
3417 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
3418 * buffer.c, data.c: Adjust users.
3420 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
3422 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
3424 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
3426 Rely on <config.h> + <unistd.h> to declare 'environ',
3427 as gnulib does this if the system doesn't.
3428 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
3429 Remove declaration. MS-Windows declares it on stdlib.h which is
3430 included by conf_post.h.
3431 * emacs.c (environ) [DOUG_LEA_MALLOC]:
3432 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
3433 * vm-limit.c: Include <unistd.h>, for 'environ'.
3435 * unexaix.c, unexcoff.c: Include "mem-limits.h".
3436 (start_of_data): Remove decl; mem-limits.h provides it.
3438 * xdisp.c (handle_invisible_prop): Make it a bit faster
3439 and avoid a gcc -Wmaybe-uninitialized diagnostic.
3441 2012-08-19 Chong Yidong <cyd@gnu.org>
3443 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
3446 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
3448 * .gdbinit: Use call instead of set when calling a function in the
3451 * data.c (set_internal): Don't use set_blv_found.
3452 (Fkill_local_variable): Likewise.
3454 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
3456 * nsfont.m (ns_ascii_average_width): Ensure the string
3457 ascii_printable is initialized with a null-terminated character
3458 array. Otherwise, it can contain undesired extra characters.
3460 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
3462 port new setting code to Sun C 5.8 2005/10/13
3463 * chartab.c, lisp.h (char_table_set, char_table_set_range):
3464 Return void, not Lisp_Object. Otherwise, the compiler
3465 complains about (A?B:C) where B is void and C is Lisp_Object
3466 when compiling CHAR_TABLE_SET, due to the recent change to
3467 the API of sub_char_table_set_contents.
3469 2012-08-18 Chong Yidong <cyd@gnu.org>
3471 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
3472 for the string case (Bug#3874).

4300 * w32.c (init_environment): Change the default values of many
4301 environment variables in dflt_envvars[] to NULL, to avoid pushing
4302 them into environment when they were not already defined.
4303 Remove the code that deletes site-lisp subdirectories from the default
4304 value of EMACSLOADPATH, as it is no longer needed.
4305 (check_windows_init_file): Now external, not static.
4306 Use Vload_path as is, without adding anything, as this function is now
4307 called when Vload_path is already set up.
4309 * w32.h (check_windows_init_file): Add prototype.
4311 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

4354 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
4355 Remove unnecessary pointer casts.
4356 * alloc.c (record_xmalloc): New function.
4357 * lisp.h (record_xmalloc): New decl.
4358 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
4359 more like a function. This is because the pointer cast is not
4360 needed. All uses changed.
4361 * print.c (print_string, print_error_message): Avoid length recalc.
4363 Improve fix for macroexp crash with debugging (Bug#12118).
4364 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
4365 ARRAY_MARK_FLAG when checking subscripts, because ASET is
4366 not supposed to be invoked from the garbage collector.

4368 (gc_aset): New function, which is like ASET but can be
4369 used in the garbage collector.

4398 with addition of handling of symlinks and support for 'lstat'.
4399 If possible, get file's attributes and security information by
4400 handle, not by name. Produce S_IFLNK bit for symlinks, when
4401 called from 'lstat'.
4402 (stat, lstat): New functions, call 'stat_worker'.
4403 (symlink, readlink, careadlinkat): Rewritten to create and resolve
4404 symlinks when the underlying filesystem supports them.
4406 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
4408 Fix macroexp crash on Windows with debugging (Bug#12118).
4409 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
4410 checking subscripts; problem introduced with the recent
4411 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
4412 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
4413 since it's used in non-static inline functions now.
4415 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
4416 Don't assume buffer size fits in 'int'. Remove unused local.

4436 * composite.c (COMPOSITE_INLINE):
4437 * dispnew.c (DISPEXTERN_INLINE):
4438 * sysdep.c (SYSTIME_INLINE):
4439 Define to EXTERN_INLINE, so that the corresponding functions
4440 are compiled into code.
4441 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
4442 (INLINE_HEADER_END): New macros.
4443 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

4463 hard-coding the path separator.
4465 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
4467 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
4468 This how ASET and AREF are supposed to work, and makes
4469 it easier to think about future improvements. See
4470 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
4471 * charset.h (set_charset_attr): New function.

4955 Reimplement to use struct Lisp_Excursion. Add comments.
4957 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
4959 Fix export of symbols to GDB (Bug#12036).
4960 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
4961 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
4962 emacs.c, as this is a more-suitable home. Had this been done earlier
4963 the fix for 12036 would have avoided some of the problems noted in
4964 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
4965 would have been more obvious.
4966 * emacs.c: Do not include <verify.h>; no longer needed.
4967 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
4968 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
4969 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
4970 Remove; now done in lisp.h.
4971 * lisp.h (PUBLISH_TO_GDB): New macro.
4972 (GCTYPEBITS, USE_LSB_TAG, CHECK_LISP_OBJECT_TYPE, enum pvec_type)
4973 (DATA_SEG_BITS): Use it.
4974 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
4975 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
4976 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
4977 not be usable in #if. This simplifies things.
4979 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
4981 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
4983 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
4985 Simplify export of symbols to GDB (Bug#12036).
4986 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
4987 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
4988 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
4989 Adjust to changes in lisp.h and emacs.c, by using
4990 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
4991 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
4992 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
4993 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
4994 instead of gdb_valbits.
4995 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
4996 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
4997 instead of gdb_array_mark_flag.
4998 (xboolvector): Get size from $->size, not $->header.size.
4999 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
5000 (xreload, hook-run, hookpost-run): Remove.
5001 * emacs.c: Include <verify.h>.
5002 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
5003 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
5005 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
5006 (gdb_USE_LSB_TAG): New enum constants.
5007 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
5008 Also define these as enum constants, so they're visible to GDB.
5009 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
5010 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
5011 as constants, so they're visible to GDB.
5012 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
5013 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
5014 Now enum constants, not macros, so they're visible to GDB.
5015 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
5016 more convenient now. All uses changed.
5017 (VALMASK) [USE_LSB_TAG]: Also define in this case.
5018 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
5020 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>
5022 Explicitly free restriction data that are not needed anymore.

5025 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
5027 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
5028 add argument, tune behavior, and adjust all callers.
5030 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
5032 Use typedef for EMACS_INT, EMACS_UINT.
5033 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
5034 than macros. This simplifies debugging in the usual case, since
5035 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
5036 and it allows expressions involving EMACS_INT casts.
5037 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
5039 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

5049 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
5051 Adjust buffer text indirection counters at the end of Fkill_buffer.
5052 * buffer.c (Fkill_buffer): Adjust indirection counters when the
5053 buffer is definitely dead. This should really fix an issue reported
5054 by Christoph Scholtes again. (Bug#12007).
5055 (init_buffer_once): Initialize indirection counters of
5056 buffer_defaults and buffer_local_symbols (for sanity and safety).
5058 2012-07-24 Eli Zaretskii <eliz@gnu.org>
5060 * xdisp.c (init_iterator): Don't compute dimensions of truncation
5061 and continuation glyphs on tooltip frames, leave them at zero.
5062 Avoids continued lines in tooltips. (Bug#11832)
5064 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
5066 Simplify copy_overlay.
5067 * buffer.c (copy_overlay): Simplify. Use build_marker.

5073 or invalid. (Bug#12025)
5075 * window.c (decode_any_window): Disable CHECK_LIVE_FRAME test, as
5076 it signals an error when a tooltip frame is being created.
5078 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
5080 Cleanup miscellaneous objects allocation and initialization.

5087 (build_overlay): Add prototype.
5089 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
5091 Swap buffer text indirection counters in Fbuffer_swap_text.
5092 * buffer.c (Fbuffer_swap_text): Swap indirections too.
5093 This avoids crash reported by Christoph Scholtes at
5094 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
5096 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
5098 * nsmenu.m (Popdown_data): New struct.

5103 and autorelease them. Also autorelease img and matrix (Bug#12005).
5104 (dealloc): Remove (Bug#12005).

5121 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
5123 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
5124 as it's limited by the amount of memory, not by INT_MAX.
5126 2012-07-21 Eli Zaretskii <eliz@gnu.org>
5128 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
5129 in special-event-map. See the discussion at

5279 2012-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
5281 * eval.c (Fdefvar): Don't check constants since we only set the var if
5282 it's not yet defined anyway (bug#11904).
5284 * lisp.h (last_undo_boundary): Declare new var.
5285 * keyboard.c (command_loop_1): Set it.
5286 * cmds.c (Fself_insert_command): Use it to only remove boundaries that
5287 were auto-added by the command loop (bug#11774).

5855 This replaces macros (which typically do not work in GDB)
5856 with functions, typedefs and enums, making the code easier to debug.
5857 The functional style also makes code easier to read and maintain.
5858 * systime.h: Include <sys/time.h> on all hosts, not just if
5859 WINDOWSNT, since 'struct timeval' is needed in general.
5860 (EMACS_TIME): Now a typedef, not a macro.
5861 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
5863 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)
5864 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE, EMACS_TIME_EQ)
5865 (EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE, EMACS_TIME_LT)
5866 (EMACS_TIME_LE): Now functions, not macros.
5867 (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
5868 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
5869 which are not functions. All uses rewritten to use:
5870 (make_emacs_time): New function.
5871 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
5872 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
5873 not functions. All uses rewritten to use the following, respectively:
5874 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
5875 (add_emacs_time, sub_emacs_time): New functions.
5876 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
5877 * fileio.c (Fcopy_file):
5878 * xterm.c (XTflash): Get the current time closer to when it's used.
5879 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.
5881 * bytecode.c (targets): Suppress -Woverride-init warnings.
5883 Simplify by avoiding confusing use of strncpy etc.
5884 * doc.c (Fsnarf_documentation):
5885 * fileio.c (Ffile_name_directory, Fsubstitute_in_file_name):
5886 * frame.c (Fmake_terminal_frame):
5887 * gtkutil.c (get_utf8_string):
5889 * nsmenu.m (ns_update_menubar):
5890 * regex.c (regerror):
5891 Prefer memcpy to strncpy and strncat when either will do.
5892 * fileio.c (Fsubstitute_in_file_name):
5893 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
5894 (menu_separator_name_p):
5895 * nsmenu.m (ns_update_menubar):
5896 Prefer memcmp to strncmp when either will do.
5897 * nsterm.m: Include <ftoastr.h>.
5899 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
5900 Prefer snprintf to strncpy.
5901 * nsterm.m (ns_term_init):
5902 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
5903 * nsterm.m (ns_term_init):
5904 Avoid the need for strncpy, by using build_string or
5905 make_unibyte_string directly. Use dtoastr, not snprintf.
5906 * process.c (Fmake_network_process): Diagnose service names that
5907 are too long, rather than silently truncating them or creating
5908 non-null-terminated names.
5909 (Fnetwork_interface_info): Likewise, for interface names.
5910 * sysdep.c (system_process_attributes) [GNU_LINUX]:
5911 Prefer sprintf to strncat.
5912 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
5913 Prefer vsnprintf to vsprintf + strncpy.
5915 2012-07-10 Glenn Morris <rgm@gnu.org>
5917 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
5918 Clarify fallback case.
5920 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
5922 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
5923 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
5924 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
5925 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
5926 where argument type is known to be a Lisp_Cons.
5928 2012-07-10 Tom Tromey <tromey@redhat.com>
5930 * bytecode.c (BYTE_CODE_THREADED): New macro.
5931 (BYTE_CODES): New macro. Replaces all old byte-code defines.
5932 (enum byte_code_op): New type.
5933 (CASE, NEXT, FIRST, CASE_DEFAULT, CASE_ABORT): New macros.
5934 (exec_byte_code): Use them. Use token threading when applicable.
5936 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
5938 Optimize pure C strings initialization.
5939 * lisp.h (make_pure_string): Fix prototype.
5940 (build_pure_c_string): New function, defined as static inline. This
5941 provides a better opportunity to optimize away calls to strlen when
5942 the function is called with compile-time constant argument.
5943 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
5944 argument, adjust users accordingly. Use build_pure_c_string where
5946 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
5947 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
5948 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
5950 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
5952 Avoid calls to strlen in miscellaneous functions.
5953 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
5954 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
5955 * lread.c (openp): Likewise.
5957 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
5959 Avoid calls to strlen in path processing functions.
5960 * fileio.c (file_name_as_directory): Add comment. Change to add
5961 srclen argument and return the length of result. Adjust users
5963 (directory_file_name): Fix comment. Change to add srclen argument,
5964 swap 1st and 2nd arguments to obey the common convention.
5965 Adjust users accordingly.
5966 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
5968 2012-07-10 Glenn Morris <rgm@gnu.org>
5970 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
5971 Move PENDING_OUTPUT_COUNT definition to configure.
5973 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
5974 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
5975 * s/gnu.h (DATA_START): Move definitions to configure.
5977 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
5978 We include usg5-4-common.h, which defines them both.
5980 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
5981 O_RDONLY already includes it).
5983 Stop ns builds setting the EMACSLOADPATH environment variable.
5984 * nsterm.m (ns_load_path): Rename from ns_init_paths.
5985 Now it does not set EMACSLOADPATH, just returns the load-path string.
5986 * nsterm.h: Update accordingly.
5987 * lread.c [HAVE_NS]: Include nsterm.h.
5988 (init_lread) [HAVE_NS]: Use ns_load_path.
5989 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
5991 2012-07-09 Glenn Morris <rgm@gnu.org>
5993 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
5994 since the included bsd-common.h does so.
5996 Stop ns builds setting the EMACSPATH environment variable.
5997 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
5998 (ns_init_paths): Do not set EMACSPATH.
5999 * nsterm.h (ns_exec_path): Add it.
6000 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
6003 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
6005 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
6007 * process.c (wait_reading_process_output): 'waitchannels' was unset
6008 when read_kbd || !NILP (wait_for_cell); fix this.
6010 Add GCC-style 'const' attribute to functions that can use it.
6011 * character.h (char_resolve_modifier_mask):
6012 * keyboard.h (make_ctrl_char):
6013 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
6014 (init_character_once, next_almost_prime, init_fns, init_image)
6015 (flush_pending_output, init_sound):
6016 * mem-limits.h (start_of_data):
6017 * menu.h (finish_menu_items):

6020 Declare the dummy function with ATTRIBUTE_CONST.
6021 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
6022 Add decls with ATTRIBUTE_CONST.
6024 Minor improvements to make_formatted_string.
6025 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
6026 where int is good enough, as vsprintf returns an int.
6027 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
6029 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
6031 Use make_formatted_string to avoid double length calculation.
6032 * lisp.h (make_formatted_string): New prototype.
6033 * alloc.c (make_formatted_string): New function.
6034 * buffer.c (Fgenerate_new_buffer_name): Use it.
6035 * dbus.c (syms_of_dbusbind): Likewise.
6036 * editfns.c (Fcurrent_time_zone): Likewise.
6037 * filelock.c (get_boot_time): Likewise.
6038 * frame.c (make_terminal_frame, set_term_frame_name)
6039 (x_report_frame_params): Likewise.
6040 * image.c (gs_load): Likewise.
6041 * minibuf.c (get_minibuffer): Likewise.
6042 * msdos.c (dos_set_window_size): Likewise.
6043 * process.c (make_process): Likewise.

6047 2012-07-09 Glenn Morris <rgm@gnu.org>
6049 Stop ns builds polluting the environment with EMACSDATA, EMACSDOC.
6050 * nsterm.m (ns_etc_directory): New function, split from ns_init_paths.
6051 (ns_init_paths): Do not set EMACSDATA, EMACSDOC.
6052 * nsterm.h (ns_etc_directory): Add it.

6054 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
6056 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
6058 Move marker debugging code under MARKER_DEBUG.
6059 * marker.c (MARKER_DEBUG): Move marker debugging code under
6060 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
6061 for bootstrap with --enable-checking (~3x slowdown reported
6062 by Juanma Barranquero <lekktu@gmail.com>).
6063 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
6065 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
6067 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
6068 See <http://bugs.gnu.org/11825#29>.
6070 2012-07-08 Eli Zaretskii <eliz@gnu.org>
6072 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
6073 has no font, use the frame's font. (Bug#11813)
6074 (display_line): Add commentary about displaying truncation glyphs
6076 (produce_special_glyphs): Move here from term.c.
6078 * term.c (produce_special_glyphs): Move to xdisp.c.
6080 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
6083 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
6085 * xdisp.c (display_line): Avoid warning about implicit declaration
6088 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
6090 * lisp.h: Remove empty conditional.
6092 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
6094 * lread.c (load_path_check): Now static.
6096 Fix some minor --with-ns problems found by static checking.
6097 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
6098 (x_set_font) [!HAVE_X_WINDOWS]:
6099 * image.c (xpm_load_image) [HAVE_NS]:
6100 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
6101 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
6102 Remove unused local.
6103 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
6104 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
6105 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
6106 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
6107 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
6108 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
6109 Fix pointer signedness problem.
6110 * xfaces.c (FRAME_X_FONT_TABLE):
6111 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
6113 2012-07-07 Glenn Morris <rgm@gnu.org>
6115 * lread.c (load_path_check): New function, split from init_lread.
6116 (init_lread): Reorganize. Motivation:
6117 If EMACSLOADPATH is set, check/warn about that rather than the
6118 defaults, which we are not going to use. Hence we can remove
6119 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
6120 Don't warn if site-lisp directories are missing.
6121 If not installed, start from a blank load-path, since
6122 PATH_LOADSEARCH refers to the eventual installation directories.
6124 2012-07-07 Eli Zaretskii <eliz@gnu.org>
6126 Support truncation and continuation glyphs on GUI frames, when
6127 fringes are disabled. (Bug#11832)
6128 * xdisp.c (init_iterator): Get dimensions of truncation and
6129 continuation glyphs even if on GUI frames.
6130 Adjust it->last_visible_x on GUI frames when the left or right fringes,
6131 or both, are absent.
6132 (start_display, move_it_in_display_line_to): Handle the case of a
6133 GUI frame without a fringe to display continuation or truncation
6135 (insert_left_trunc_glyphs): Support GUI frames: make sure
6136 truncation glyphs overwrite enough glyphs from the current line to
6137 have sufficient space in pixels.
6138 (display_line): Support truncation and continuation glyphs on GUI
6139 frames. If some spare pixels are left on the line after inserting
6140 the truncation glyphs, fill that space with a stretch glyph of a
6141 suitably computed width.
6143 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
6144 produce_glyphs, to support GUI sessions.
6146 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
6148 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
6150 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
6152 Do not require float-time's arg to fit in time_t (Bug#11825).
6153 This works better on hosts where time_t is unsigned, and where
6154 float-time is applied to the (negative) difference between two times.
6155 * editfns.c (decode_time_components): Last arg is now double *,
6156 not int *, and means to store all the result as a double, without
6157 worrying about whether the seconds part fits in time_t.
6158 All callers changed.
6159 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
6160 All callers changed.
6161 (Ffloat_time): Do not fail merely because the specified time falls
6162 outside of time_t range.
6164 2012-07-07 Glenn Morris <rgm@gnu.org>
6166 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
6167 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
6168 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
6170 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
6172 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
6173 Update dependencies.
6175 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
6177 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
6179 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
6180 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
6181 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
6182 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
6183 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
6184 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
6186 * xfont.c (compare_font_names): Redo to omit the need for casts.
6188 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
6190 * xfns.c (Fx_change_window_property): Doc fix.
6191 * w32fns.c (Fx_change_window_property): Doc fix.
6193 * w32fns.c (Fx_window_property): Accept the same arguments as the
6194 X Windows version. Doc fix.
6195 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
6197 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
6198 Eli Zaretskii <eliz@gnu.org>
6200 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
6201 Windows-specific code from nt/config.nt moved here.
6202 Obsolete settings removed.
6204 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
6206 * process.c: Avoid unnecessary calls to gettime.
6207 (wait_reading_process_output): Don't get the time of day
6208 when gobbling data immediately and not waiting, as there's no need
6209 for it in that case. This removes a FIXME.
6211 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
6213 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
6214 is defined (Bug#11768).
6216 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6218 Fix marker debugging code.
6219 * marker.c (byte_char_debug_check): Do not perform the check
6220 if buffer is not multibyte.
6221 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
6222 Call byte_char_debug_check with correct arguments.
6224 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6226 Compile marker debugging code only if ENABLE_CHECKING is defined.
6227 * marker.c (byte_char_debug_check, count_markers):
6228 Use only if ENABLE_CHECKING is defined.
6229 (byte_debug_flag): Remove.
6230 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
6231 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
6233 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6235 Avoid code repetition in marker-related functions.
6236 * marker.c (attach_marker): New function.
6237 (Fset_marker, set_marker_restricted, set_marker_both)
6238 (set_marker_restricted_both): Use it.
6239 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
6240 Consistently rename charno to charpos.
6241 (marker_position): Add eassert.
6242 (marker_byte_position): Convert to eassert.
6244 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6246 Simplify list operations in unchain_overlay and unchain_marker.
6247 * buffer.c (unchain_overlay): Simplify. Add comment.
6248 * marker.c (unchain_marker): Simplify. Fix comments.
6250 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6252 Introduce fast path for the widely used marker operation.
6253 * alloc.c (build_marker): New function.

6259 (save_restriction_save): Use build_marker.
6260 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
6261 * window.c (save_window_save): Likewise.
6263 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6265 Do not use Fdelete_overlay in delete_all_overlays
6266 to avoid redundant calls to unchain_overlay.
6267 * buffer.c (drop_overlay): New function.
6268 (delete_all_overlays, Fdelete_overlay): Use it.
6269 * minibuf.c (get_minibuffer): Fix comment.
6271 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
6273 Port to OpenBSD 5.1 amd64.
6274 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
6275 This is needed for OpenBSD, and should be harmless on all BSD systems.
6276 Also, include <sys/sysctl.h>, as it should be available on all
6277 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
6278 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
6279 use p_pid member, not kp_proc.pid.
6281 2012-07-06 Glenn Morris <rgm@gnu.org>
6283 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
6285 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
6287 More xmalloc and related cleanup.
6288 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
6289 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:

6296 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
6298 Omit needless casts involving void * pointers and allocation.
6299 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
6300 as the former is more robust if P's type is changed.
6301 Prefer xzalloc to xmalloc + memset 0.
6302 Simplify malloc-or-realloc to realloc.
6303 Don't worry about xmalloc returning a null pointer.
6304 Prefer xstrdup to xmalloc + strcpy.
6305 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
6307 * keyboard.c (apply_modifiers_uncached): Prefer local array to
6308 alloca of a constant.
6310 2012-07-05 Eli Zaretskii <eliz@gnu.org>
6312 * xdisp.c (display_line): Fix horizontal pixel coordinates when
6313 hscroll is larger than the line width. Fixes long and futile
6314 looping inside extend_face_to_end_of_line (on a TTY) producing
6315 glyphs that are not needed and thrown away.
6317 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>

6329 not defined (Bug#11768).
6330 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
6331 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
6332 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
6333 followed by gtk_box_set_homogeneous (Bug#11768).
6334 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
6335 (update_theme_scrollbar_width, xg_create_scroll_bar):
6336 Use gtk_scrollbar_new (Bug#11768).
6337 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.

6345 * xdisp.c (window_hscroll_limited): New function.
6346 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
6347 coordinates when window's hscroll is set to insanely large

6414 Problem reported by Troels Nielsen in
6415 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.

6419 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
6420 This should be fixed in a better way; see Eli Zaretskii in
6421 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
6422 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
6424 * fileio.c (time_error_value): Rename from special_mtime.
6425 The old name's problems were noted by Eli Zaretskii in
6426 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
6428 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
6429 This variable's comment says Emacs needs at least one GDB-visible
6430 symbol of type enum pvec_type, to work around GDB problems.
6431 The symbol's value doesn't matter.
6433 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
6434 that causes compilation to fail on pre-C99 compilers.
6436 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
6438 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

6444 headers for buffer_defaults and buffer_local_symbols.
6445 Reported by Juanma Barranquero <lekktu@gmail.com>.
6447 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
6449 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
6450 * lisp.h (enum pvec_type): Use fewer bits.
6451 (PSEUDOVECTOR_SIZE_BITS): New constant.
6452 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
6453 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
6454 change in pvec_type.
6455 (PSEUDOVECTOR_TYPEP): New macro.
6456 (TYPED_PSEUDOVECTORP): Use it.
6457 * fns.c (internal_equal): Adapt code to extract pvectype.

6461 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
6462 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
6463 (sweep_vectors): Use it. Use local var `total_bytes' instead of
6464 abusing vector->header.next.nbytes.
6465 (live_vector_p): Use PVEC_TYPE.
6466 (mark_object): Adapt code to extract pvectype. Use switch.
6468 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
6470 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
6471 Tighten new eassert a bit.
6473 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
6475 Fix compilation with --enable-gcc-warnings and -O1
6477 * doprnt.c (doprnt): Change type of tem to int, initialize
6478 to avoid compiler warning. Add eassert.
6479 * search.c (simple_search): Initialize match_byte to avoid
6480 compiler warning. Add eassert.
6482 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
6484 Avoid weird behavior with large horizontal scrolls.
6485 Without this change, for example, large hscroll values would
6486 mess up Emacs's display on Fedora 15 x86, presumably due to
6487 overflows in int calculations in the display code.
6488 Also, if buffers had long lines, Emacs would freeze.
6489 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
6490 (set_window_hscroll): New function, containing the old guts of
6491 Fset_window_hscroll. Return the clipped value.
6492 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
6493 This avoids the need to check against PTRDIFF_MAX.
6495 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
6497 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
6499 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
6501 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
6503 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
6504 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
6505 since GCC 4.4.6 issues a bogus warning for them.
6507 Fix bugs in file timestamp newness comparisons.
6508 * fileio.c (Ffile_newer_than_file_p):
6509 * lread.c (Fload): Use full timestamp resolution of files,
6510 not just the 1-second resolution, so that files that are only
6511 slightly newer still count as newer.
6512 * fileio.c (Ffile_newer_than_file_p): Don't assume file
6513 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
6515 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
6517 * fileio.c: Improve handling of file time marker. (Bug#11852)
6518 (special_mtime): New function.
6519 (Finsert_file_contents, Fverify_visited_file_modtime):
6520 Use it to set special mtime values consistently.
6522 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
6524 * fileio.c (Finsert_file_contents): Properly handle st_mtime
6525 marker for non-existing file. (Bug#11852)
6527 2012-07-03 Glenn Morris <rgm@gnu.org>
6529 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
6530 and did not make it into globals.h).
6532 2012-07-03 Tom Tromey <tromey@redhat.com>
6534 * window.c (Fset_window_margins, Fset_window_fringes)

6568 * xterm.h: Remove EXFUN.
6570 2012-07-03 Glenn Morris <rgm@gnu.org>
6572 * lisp.h (Frandom): Make it visible to C.
6573 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
6574 buffer for invisible buffers. (Bug#1229)
6576 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
6578 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
6579 values which aren't power of 2.
6580 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
6581 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
6584 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
6586 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
6588 * alloc.c (mark_object): Revert part of last patch to use `switch'.
6590 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
6592 * alloc.c (allocate_vector_block): Remove redundant
6593 calls to mallopt if DOUG_LEA_MALLOC is defined.
6594 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
6595 avoid calls to mallopt if zero_vector is returned.
6597 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
6599 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
6600 is enabled, avoid dereferencing NULL current_sblock if
6603 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
6605 Cleanup basic buffer management.
6606 * buffer.h (struct buffer): Change layout to use generic vector
6607 marking code. Fix some comments. Change type of 'clip_changed'
6608 to bitfield. Remove unused #ifndef old.
6609 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
6610 (GET_OVERLAYS_AT): Fix indentation.
6611 (for_each_per_buffer_object_at): New macro.
6612 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)

6614 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
6615 * alloc.c (allocate_buffer): Adjust to match new layout of
6616 struct buffer. Fix comment.
6617 (mark_overlay): New function.

6619 Lisp area of struct buffer.
6620 (mark_object): Use it. Adjust marking of misc objects
6621 and related comments.
6623 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
6625 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
6626 wrapper that is not needed because the wrapped code is a no-op (zero
6627 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
6628 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
6630 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
6632 * alloc.c (mark_buffer): Simplify. Remove prototype.
6633 (mark_object): Add comment. Reorganize marking of vector-like
6634 objects. Use CHECK_LIVE for all vector-like objects except buffers
6635 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
6636 Avoid redundant calls to mark_vectorlike for bool vectors.
6638 2012-06-30 Glenn Morris <rgm@gnu.org>
6640 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
6642 * epaths.in (PATH_SITELOADSEARCH): New.
6643 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
6644 This is rather than relying on --enable-locallisppath elements
6645 having "site-lisp" in their names. (Bug#10208#25, 11658)
6647 2012-06-30 Eli Zaretskii <eliz@gnu.org>
6649 * w32proc.c (sys_select): Accept and ignore one more argument.
6651 * w32.c (emacs_gnutls_pull): Call select with one more argument.
6653 * sysselect.h [DOS_NT]: Don't include sys/select.h.
6654 (pselect) [!MS_DOS]: Redirect to sys_select.
6656 * sysdep.c: Don't include dos.h and dosfns.h.
6658 * process.c (sys_select):
6659 * msdos.c (sys_select): Accept one more argument and ignore it.
6661 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
6662 adapt data types and code to that.
6665 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
6666 which clashes with the gnulib function of the same name.
6668 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
6670 * font.c (font_style_to_value, font_style_symbolic)
6671 (font_prop_validate_style): Add type checks for values in
6674 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
6676 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
6679 2012-06-29 Eli Zaretskii <eliz@gnu.org>
6681 * xdisp.c (try_window_id): Undo last change.
6683 * w32.c (getwd): Adjust commentary about startup_dir.
6684 (init_environment): Always call sys_access, even in non-MSVC
6685 builds. Don't chdir to the directory of the Emacs executable.
6686 This undoes code from 1997 which was justified by the need to
6687 "avoid conflicts when removing and renaming directories". But its
6688 downside was that every relative file name was being interpreted
6689 relative to the directory of the Emacs executable, which can never
6690 be TRT. In particular, it broke sys_access when called with
6691 relative file names.
6692 (sys_access): Map GetLastError to errno.
6694 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
6696 * window.h (struct window): Change type of 'fringes_outside_margins'

6700 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
6703 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
6705 * gnutls.c (emacs_gnutls_handshake):
6706 Add QUIT to make the loop interruptible.
6708 2012-06-29 Glenn Morris <rgm@gnu.org>
6710 * charset.c (init_charset): Make lack of etc/charsets fatal.
6712 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
6714 * editfns.c (region_limit): Fix type mismatch.
6716 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
6718 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
6719 undefined. Convert from xassert to eassert.
6720 * nsmenu.m: Convert from xassert to eassert.
6721 * nsterm.m: Likewise.
6723 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
6725 * editfns.c (region_limit): Clip to narrowing (bug#11770).
6727 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
6729 Avoid integer overflow on scroll-left and scroll-right.
6730 * window.c (HSCROLL_MAX): New macro.
6731 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
6732 overflow when requested scroll falls outside ptrdiff_t range.
6734 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
6736 * window.h (struct window): Change type of 'hscroll',
6737 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
6738 'last_modified' and 'last_overlay_modified' to EMACS_INT.
6739 Adjust users accordingly.
6740 * xdisp.c (try_cursor_movement): Replace type check with eassert.
6741 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
6742 from EMACS_INT to ptrdiff_t.
6743 (make_window): Omit redundant initialization.
6745 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
6747 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
6749 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
6751 * window.h (struct window): Change type of 'use_time' and
6752 'sequence_number' from Lisp_Object to int.
6753 * frame.c (make_frame): Adjust users accordingly.
6754 * print.c (print_object): Likewise.
6755 * window.c (select_window, Fwindow_use_time, make_parent_window)
6756 (make_window): Likewise.
6758 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
6760 * dispextern.h (GLYPH_DEBUG): Now defined in config.h if
6761 enabled with --enable-checking=[all,glyphs] configure option.
6762 Fix GLYPH_DEBUG usage assuming that it may be undefined,
6763 adjust comments accordingly.
6764 * dispnew.c: Fix GLYPH_DEBUG usage assuming that it may be
6765 undefined, adjust comments accordingly.

6884 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
6886 Use sprintf return value instead of invoking strlen on result.
6887 In the old days this wasn't portable, since some sprintf
6888 implementations returned char *. But they died out years ago and
6889 Emacs already assumes sprintf returns int.
6890 Similarly for float_to_string.
6891 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

6899 Use sprintf or float_to_string result to avoid need to call strlen.
6900 * data.c (Fnumber_to_string):
6901 Use make_unibyte_string, since the string must be ASCII.
6902 * lisp.h, print.c (float_to_string): Now returns int length.
6903 * term.c (produce_glyphless_glyph):
6904 Use sprintf result rather than recomputing it.
6906 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
6907 * Makefile.in (ALL_CFLAGS):
6908 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

6937 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
6939 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

6942 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
6944 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
6945 instead of truncating it to 63 (admittedly a generous limit).

7005 * keyboard.c (kbd_buffer_get_event):
7006 * process.c (Faccept_process_output):
7007 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
7008 This improves on the previous patch, which introduced a bug
7009 when time_t is unsigned and as wide as intmax_t.
7010 See <http://bugs.gnu.org/9000#51>.
7012 2012-06-23 Eli Zaretskii <eliz@gnu.org>

7075 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
7077 Support higher-resolution time stamps (Bug#9000).
7078 The time stamps are only nanosecond-resolution at the C level,
7079 since that's the best that any real-world system supports now.
7080 But they are picosecond-resolution at the Lisp level, as that's
7081 easy, and leaves room for future OS improvements.
7083 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
7086 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
7087 Don't get current time unless it's needed.
7089 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
7090 now provides it if it's absent.
7091 (start_atimer): Port to higher-res time stamps.
7092 Check for time stamp overflow. Don't get current time more
7093 often than is needed.
7095 * buffer.h (struct buffer): Buffer modtime now has high resolution.
7096 Include systime.h, not time.h.
7097 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
7099 * dired.c: Include stat-time.h.
7100 (Ffile-attributes): File times now have higher resolution.
7102 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
7103 (struct image): Timestamp now has higher resolution.
7105 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
7106 has at least microseconds now. All uses removed.
7107 (update_frame, update_single_window, update_window, update_frame_1)
7108 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
7109 (duration_to_sec_usec): Remove; no longer needed.
7111 * editfns.c (time_overflow): Now extern.
7112 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
7113 (float-time, Fformat_time_string, Fcurrent_time_string)

7117 (decode_time_components, lisp_seconds_argument): New functions.
7118 (make_time): Now static.
7119 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
7120 Report an error if the time is invalid, rather than having the caller
7123 * fileio.c: Include <stat-time.h>
7124 (Fcopy_file): Copy higher-resolution time stamps.
7125 Prefer to set the time stamp via a file descriptor if that works.
7126 (Fset_file_times, Finsert_file_contents, Fwrite_region)
7127 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
7128 (Fvisited_file_modtime, Fset_visited_file_modtime):
7129 Support higher-resolution time stamps.
7131 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
7133 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
7135 * image.c (prepare_image_for_display, clear_image_cache)
7136 (lookup_image): Port to higer-resolution time stamps.
7138 * keyboard.c (start_polling, bind_polling_period):
7139 Check for time stamp overflow.
7140 (read_char, kbd_buffer_get_event, timer_start_idle)
7141 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
7142 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
7143 Port to higher-resolution time stamps. Do not assume time_t is signed.
7144 (decode_timer): New function. Timers are now vectors of length 9,
7145 not 8, to accommodate the picosecond component.
7146 (timer_check_2): Use it.
7148 * nsterm.m (select_timeout, timeval_subtract): Remove.
7149 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
7150 as they're a bit more accurate and handle overflow better.
7151 (ns_select): Change prototype to be compatible with pselect.
7152 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
7153 * nsterm.h (ns_select): Adjust prototype.
7155 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
7156 us-resolution time stamps.
7157 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
7159 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
7161 * lisp.h (time_overflow): New decl.
7162 (wait_reading_process_output): First arg is now intmax_t, not int,
7163 to accommodate larger waits.
7165 * process.h (struct Lisp_Process.read_output_delay):
7166 Now counts nanoseconds, not microseconds.
7167 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
7169 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
7170 (wait_reading_process_output):
7171 Port to ns-resolution time stamps.
7172 (Faccept_process_output, wait_reading_process_output):
7173 Check for time stamp overflow. Do not assume time_t is signed.
7174 (select_wrapper): Remove; we now use pselect.
7175 (Fprocess_attributes): Now generates ns-resolution time stamps.
7177 * sysdep.c: Include utimens.h. Don't include utime.h
7178 or worry about struct utimbuf; gnulib does that for us now.
7179 (gettimeofday): Remove; gnulib provides a substitute.
7180 (make_timeval): New function.
7181 (set_file_times): Now sets ns-resolution time stamps.
7182 New arg FD; all uses changed.
7183 (time_from_jiffies, ltime_from_jiffies, get_up_time)
7184 (system_process_attributes):
7185 Now returns ns-resolution time stamp. All uses changed.
7186 Check for time stamp overflow.
7188 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
7189 provides a substitute now.
7191 * systime.h: Include timespec.h rather than sys/time.h and time.h,
7192 since it guarantees struct timespec.
7193 (EMACS_TIME): Now struct timespec, so that we can support
7194 ns-resolution time stamps.
7195 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
7196 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
7197 (EMACS_USECS): Remove.
7198 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
7199 so multiply the arg by 1000 before storing it.
7200 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
7202 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
7203 Port to ns-resolution time stamps.
7204 (EMACS_TIME_NEG_P): Remove; replaced by....
7205 (EMACS_TIME_SIGN): New macro.
7206 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
7207 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
7208 (set_file_times, make_time, lisp_time_argument): Adjust signature.
7209 (make_timeval, make_lisp_time, decode_time_components): New decls.
7210 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
7211 that it mishandled time_t overflow. You can't compare by subtracting!
7212 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
7213 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
7215 * term.c: Include <sys/time.h>.
7216 (timeval_to_Time): New function, for proper overflow wraparound.
7217 (term_mouse_position, term_mouse_click): Use it.
7219 * undo.c (record_first_change): Support higher-resolution time stamps
7221 (Fprimitive_undo): Use them when restoring time stamps.
7223 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
7224 (w32_get_internal_run_time):
7225 Port to higher-resolution Emacs time stamps.
7226 (ltime): Now accepts single 64-bit integer, as that's more convenient
7229 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
7231 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
7232 for compatibility with pselect. Support ns-resolution time stamps.
7234 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
7236 * xselect.c (wait_for_property_change, x_get_foreign_selection):
7237 Check for time stamp overflow, and support ns-resolution time stamps.
7239 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
7240 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
7241 (timeval_subtract): Remove; no longer needed.
7242 (XTflash, XTring_bell, x_wait_for_event):
7243 Port to ns-resolution time stamps. Don't assume time_t is signed.
7245 2012-06-22 Chong Yidong <cyd@gnu.org>
7247 * xdisp.c (x_consider_frame_title): Revert last change.
7249 2012-06-22 Eli Zaretskii <eliz@gnu.org>
7251 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled

7527 as the union type is for debugging, not for production.
7528 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
7529 Use an inline function on all platforms when using the union type,
7530 since this is simpler and 'static inline' can be used portably

7674 * doprnt.c (doprnt): Truncate multibyte char correctly.
7675 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
7676 would mishandle a string argument "Xc" if X was a multibyte
7677 character of length 2: it would truncate after X's first byte
7678 rather than including all of X.

7729 * minibuf.c (Fassoc_string): Remove duplicate declaration.
7731 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
7732 Convert pctcpu and pctmem to Lisp float properly.
7733 Let the compiler fold better, as 100.0/0x8000 is exact.
7735 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
7737 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
7740 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
7742 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
7744 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
7746 For a 'struct window', replace some Lisp_Object fields to
7747 bitfields where appropriate, remove unused fields.
7748 * window.h (struct window): Remove unused 'last_mark_x' and
7749 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
7750 change its type from Lisp_Object to bitfield.
7751 Change type of 'force_start', 'optional_new_start',
7752 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
7753 fields from Lisp_Object to bitfield. Adjust users accordingly.
7755 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
7757 Pacify gcc -Wdouble-precision when using Xaw.
7758 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
7759 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
7760 Use 'float' consistently, rather than 'float' in most places
7761 and 'double' in a couple of places.
7763 2012-05-31 Eli Zaretskii <eliz@gnu.org>
7765 * xdisp.c (handle_stop): Detect whether we have overlay strings
7766 loaded by testing it->current.overlay_string_index to be
7767 non-negative, instead of checking whether n_overlay_strings is
7768 positive. (Bug#11587)
7770 2012-05-31 Chong Yidong <cyd@gnu.org>
7772 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
7774 * doc.c (Fsubstitute_command_keys): Doc fix.
7776 2012-05-31 Eli Zaretskii <eliz@gnu.org>
7778 * search.c (search_buffer): Remove calls to
7779 r_alloc_inhibit_buffer_relocation, as it is now called by
7780 maybe_unify_char, which was the cause of relocation of buffer text
7783 2012-05-31 Eli Zaretskii <eliz@gnu.org>
7785 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
7786 for the duration of call to load_charset, to avoid problems with
7787 callers of maybe_unify_char that access buffer text through C
7790 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
7791 decrement the inhibition flag, instead of just setting or
7794 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
7796 Remove obsolete '#define static' cruft.
7797 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
7798 This #undef was "temporary" in 2000; it is no longer needed
7799 now that '#define static' has gone away.
7800 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
7801 (gray_bitmap_bits): Remove; no longer needed.
7802 All uses replaced with definiens.
7803 * xterm.c: Include "bitmaps/gray.xbm".
7805 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
7807 Clean up __executable_start, monstartup when --enable-profiling.
7808 The following changes affect the code only when profiling.
7809 * dispnew.c (__executable_start): Rename from safe_bcopy.
7810 Define only on platforms that need it.
7811 * emacs.c: Include <sys/gmon.h> when profiling.
7812 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
7813 (__executable_start): Remove decl, since lisp.h does it now.
7814 (safe_bcopy): Remove decl; no longer has that name.
7815 (main): Coalesce #if into single bit of code, for simplicity.
7816 Cast pointers to uintptr_t, since standard libraries want integers
7818 * lisp.h (__executable_start): New decl.
7820 2012-05-31 Glenn Morris <rgm@gnu.org>
7822 * image.c (Fimagemagick_types): Doc fix.
7824 2012-05-30 Jim Meyering <meyering@redhat.com>
7826 * callproc.c (Fcall_process_region): Include directory component
7827 in mkstemp error message (Bug#11586).
7829 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
7831 * alloc.c, lisp.h (make_pure_vector): Now static.
7833 2012-05-30 Stefan Monnier <monnier@iro.umontreal.ca>

7839 (Qdefun): Move from eval.c.
7840 * lisp.h (Qdefun): Remove.
7841 * lread.c (read1): Tiny simplification.
7843 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
7845 Do not create empty overlays with the evaporate property (Bug#9642).
7846 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
7847 Bug#9642, but explicitly check that the buffer the overlay would
7848 be moved to is live and rearrange lines to make sure that errors
7849 will not put the overlay in an inconsistent state.
7850 (Fdelete_overlay): Cosmetics.
7852 2012-05-28 Eli Zaretskii <eliz@gnu.org>
7854 * w32term.c (my_bring_window_to_top): New function.
7855 (x_raise_frame): Use handle returned by DeferWindowPos, which
7856 could be different from the original one.
7857 Call my_bring_window_to_top instead of my_set_foreground_window.
7860 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
7861 by calling BringWindowToTop.
7863 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
7864 (WM_EMACS_END): Increase by one.
7866 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
7868 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
7869 This avoids undefined behavior that might cause the eassert
7870 to not catch an out-of-range value.
7872 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
7874 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
7875 Update dependencies.
7877 2012-05-27 Eli Zaretskii <eliz@gnu.org>
7879 * bidi.c (bidi_mirror_char): Fix last change.
7881 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
7883 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
7884 when referring to sectname field in printf format.
7886 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
7888 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
7889 Only r_alloc_inhibit_buffer_relocation needed to be added;
7890 the others were already declared.
7892 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
7893 before checking whether it's out of range. Put the check inside
7895 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
7897 2012-05-27 Ken Brown <kbrown@cornell.edu>
7899 * callproc.c (Fcall_process): Restore a line that was accidentally
7900 commented out in the 2011-02-13 change (bug#11547).
7902 2012-05-27 Eli Zaretskii <eliz@gnu.org>
7904 * lisp.h [REL_ALLOC]: Add prototypes for external functions
7905 defined on ralloc.c.
7907 * buffer.c [REL_ALLOC]: Remove prototypes of
7908 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
7909 they are now on lisp.h.
7911 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
7913 * search.c (search_buffer): Use it to inhibit relocation of buffer
7914 text while re_search_2 is doing its job, because re_search_2 is
7915 passed C pointers to buffer text. (Bug#11519)
7917 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
7920 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
7921 state after an additional call to move_it_in_display_line_to, keep
7922 the values of it->max_ascent and it->max_descent found for the
7924 (pos_visible_p): Revert the comparison against bottom_y to what it
7925 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
7928 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
7930 Fix coding-related core dumps with gcc -ftrapv.
7931 The code was computing A - B, where A and B are pointers, and B is
7932 random garbage. This can lead to core dumps on platforms that
7933 have special pointer registers, and it also leads to core dumps on
7934 x86-64 when compiled with gcc -ftrapv. The fix is to compute
7935 A - B only when B is initialized properly.
7936 * coding.c (coding_set_source, coding_set_destination): Return void.
7937 (coding_change_source, coding_change_destinations): New functions,
7938 with the old behaviors of coding_set_source and coding_set_destination.
7939 All callers that need an offset changed to use these new functions.
7941 2012-05-26 Glenn Morris <rgm@gnu.org>
7943 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
7945 2012-05-26 Eli Zaretskii <eliz@gnu.org>
7947 Extend mouse support on W32 text-mode console.
7948 * xdisp.c (draw_row_with_mouse_face):
7949 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
7951 * w32console.c: Include window.h.
7952 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
7954 (initialize_w32_display): Initialize mouse-highlight data.
7956 * w32inevt.c: Include termchar.h and window.h.
7957 (do_mouse_event): Support mouse-autoselect-window. When the mouse
7958 moves, call note_mouse_highlight. If help_echo changed, call
7959 gen_help_event to produce help-echo message in the echo area.
7960 Call clear_mouse_face if mouse_face_hidden is set in the mouse
7963 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
7965 * lread.c (read1): Simplify slightly to avoid an overflow warning
7966 with GCC 4.7.0 on x86-64.
7968 2012-05-26 Eli Zaretskii <eliz@gnu.org>
7970 * bidi.c (bidi_mirror_char): Revert last change: an int is
7971 definitely wide enough here.
7973 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
7975 Fix integer width and related bugs (Bug#9874).
7976 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
7977 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
7978 (string_bytes, check_sblock, allocate_string_data):
7979 (compact_small_strings, Fmake_bool_vector, make_string)
7980 (make_unibyte_string, make_multibyte_string)
7981 (make_string_from_bytes, make_specified_string)
7982 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
7983 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
7985 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
7986 (allocate_pseudovector):
7987 Use int, not EMACS_INT, where int is wide enough.
7988 (inhibit_garbage_collection, Fgarbage_collect):
7989 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
7990 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
7991 int might not be wide enough.
7992 (bidi_cache_search, bidi_cache_find, bidi_init_it)
7993 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
7994 (bidi_at_paragraph_end, bidi_find_paragraph_start)
7995 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
7996 (bidi_level_of_next_char, bidi_move_to_visually_next):
7997 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
7998 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
7999 (Fkill_buffer, Fset_buffer_major_mode)
8000 (advance_to_char_boundary, Fbuffer_swap_text)
8001 (Fset_buffer_multibyte, overlays_at, overlays_in)
8002 (overlay_touches_p, struct sortvec, record_overlay_string)
8003 (overlay_strings, recenter_overlay_lists)
8004 (adjust_overlays_for_insert, adjust_overlays_for_delete)
8005 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
8006 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
8007 (Foverlay_recenter, last_overlay_modification_hooks_used)
8008 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
8009 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8010 (validate_region): Omit unnecessary test for b <= e,
8011 since that's guaranteed by the previous test.
8012 (adjust_overlays_for_delete): Avoid pos + length overflow.
8013 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
8014 (report_overlay_modification):
8015 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
8016 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
8017 Omit pointer cast, which isn't needed anyway, and doesn't work
8018 after the EMACS_INT -> ptrdiff_t change.
8019 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
8020 * buffer.h: Adjust decls to match defn changes elsewhere.
8021 (struct buffer_text, struct buffer):
8022 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8023 Use EMACS_INT, not int, where int might not be wide enough.
8024 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
8025 not int, to avoid needless 32-bit limit on 64-bit hosts.
8026 (exec_byte_code): Use tighter memory-full test, one that checks
8027 for alloca overflow. Don't compute the address of the object just
8028 before an array, as that's not portable. Use EMACS_INT, not
8029 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
8030 * callint.c (Fcall_interactively):
8031 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
8032 * callproc.c (call_process_kill, Fcall_process):
8033 Don't assume pid_t fits into an Emacs fixnum.
8034 (call_process_cleanup, Fcall_process, child_setup):
8035 Don't assume pid_t fits into int.
8036 (call_process_cleanup, Fcall_process, delete_temp_file)
8037 (Fcall_process_region):
8038 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
8039 (Fcall_process): Simplify handling of volatile integers.
8040 Use int, not EMACS_INT, where int will do.
8041 * casefiddle.c (casify_object, casify_region, operate_on_word)
8042 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
8043 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8044 (casify_object): Avoid integer overflow when overallocating buffer.
8045 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
8046 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
8047 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
8048 * category.h (CATEGORYP): Don't assume arg is nonnegative.
8049 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
8050 integers are now checked earlier. All uses replaced with XINT.
8052 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8053 For CCL_MapSingle, check that content and value are in int range.
8054 (ccl_driver, Fregister_code_conversion_map):
8055 Check that Vcode_version_map_vector is a vector.
8056 (resolve_symbol_ccl_program): Check that vector header is in range.
8057 Always copy the vector, so that we can check its contents reliably
8058 now rather than having to recheck each instruction as it's being
8059 executed. Check that vector words fit in 'int'.
8060 (ccl_get_compiled_code, Fregister_ccl_program)
8061 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
8062 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
8063 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
8064 contents are in range.
8065 (Fccl_execute_on_string): Check that status is in range.
8066 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
8067 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
8068 Accept and return EMACS_INT, not int, because callers can pass values
8070 (c_string_width, strwidth, lisp_string_width, chars_in_text)
8071 (multibyte_chars_in_text, parse_str_as_multibyte)
8072 (str_as_multibyte, count_size_as_multibyte, str_to_multibyte)
8073 (str_as_unibyte, str_to_unibyte, string_count_byte8)
8074 (string_escape_byte8, Fget_byte):
8075 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8076 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
8077 avoid mishandling large integers.
8078 * character.h: Adjust decls to match defn changes elsewhere.
8079 * charset.c (load_charset_map_from_file, find_charsets_in_text)
8080 (Ffind_charset_region):
8081 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
8082 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
8083 (load_charset_map_from_vector, Fdefine_charset_internal):
8084 Don't assume fixnum fits in int.
8085 (load_charset_map_from_vector, Fmap_charset_chars):
8086 Remove now-unnecessary CHECK_NATNUMs.
8087 (Fdefine_charset_internal): Check ranges here, more carefully.
8088 Don't rely on undefined behavior with signed left shift overflow.
8089 Don't assume unsigned int fits into fixnum, or that fixnum fits
8090 into unsigned int. Don't require max_code to be a valid fixnum;
8091 that's not true for gb10830 4-byte on a 32-bit host. Allow
8092 invalid_code to be a cons, for the same reason. Require code_offset
8093 to be a character. Avoid int overflow if max_char is close
8095 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
8096 this is intended anyway and avoids some undefined behavior.
8097 (load_charset_map): Pass unsigned, not int, as 2nd arg of
8098 INDEX_TO_CODE_POINT, as that's what it expects.
8099 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
8100 * charset.h (DECODE_CHAR): Return int, not unsigned;
8101 this is what was intended anyway, and it avoids undefined behavior.
8102 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
8103 integer-overflow issues.
8104 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
8105 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
8106 where the argument is EMACS_INT, and this behavior is not intended.
8107 * chartab.c (Fmake_char_table, Fset_char_table_range)
8108 (uniprop_get_decoder, uniprop_get_encoder):
8109 Don't assume fixnum fits in int.
8110 * cmds.c (move_point): New function, that does the gist of
8111 Fforward_char and Fbackward_char, but does so while checking
8112 for integer overflow more accurately.
8113 (Fforward_char, Fbackward_char): Use it.
8114 (Fforward_line, Fend_of_line, internal_self_insert)
8115 (internal_self_insert):
8116 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8117 Fix a FIXME, by checking for integer overflow when calculating
8118 target_clm and actual_clm.
8119 * coding.c (detect_coding_XXX, encode_coding_XXX, CODING_DECODE_CHAR)

8866 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
8868 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
8869 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
8871 2012-05-18 Eli Zaretskii <eliz@gnu.org>
8873 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
8875 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
8876 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
8878 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
8879 reference to image_cache->refcount.
8880 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
8882 2012-05-17 Juri Linkov <juri@jurta.org>
8884 * search.c (Fword_search_regexp, Fword_search_backward)
8885 (Fword_search_forward, Fword_search_backward_lax)
8886 (Fword_search_forward_lax): Move functions to isearch.el
8887 (bug#10145, bug#11381).
8889 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
8891 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
8893 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
8895 * lread.c (init_obarray): Declare Qt and Qnil as special.
8897 2012-05-14 Glenn Morris <rgm@gnu.org>
8899 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
8900 Put "libexec" before "bin", for the sake of init_callproc_1.
8902 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
8904 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
8906 * unexaix.c: Port to more-recent AIX compilers.
8907 (report_error, report_error_1, make_hdr, copy_sym)
8908 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
8909 Make arguments const char *, not char *, to avoid violations of C
8910 standard and to fix some AIX warnings reported by Gilles Pion.
8912 2012-05-14 Eli Zaretskii <eliz@gnu.org>
8914 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
8915 already have overlays loaded.
8916 (handle_single_display_spec): Before returning without displaying
8917 fringe bitmap, synchronize the bidi iterator with the main display
8918 iterator, by calling iterate_out_of_display_property.
8919 (iterate_out_of_display_property): Detect buffer iteration by
8920 testing that it->string is a Lisp string.
8921 (get_next_display_element): When the current object is exhausted,
8922 and there's something on it->stack, call set_iterator_to_next to
8923 proceed with what's on the stack, instead of returning zero.
8924 (set_iterator_to_next): If called at the end of a Lisp string,
8925 proceed to consider_string_end without incrementing string
8926 position. Don't increment display vector index past the end of
8927 the display vector. (Bug#11417)
8928 (pos_visible_p): Don't report a position visible when move_it_to
8929 stopped at the last line of window, which happens to be scanned
8930 backwards by the bidi iteration. (Bug#11464)
8932 2012-05-14 Eli Zaretskii <eliz@gnu.org>
8934 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
8935 and right-margin display specs even if the spec is invalid or we
8936 are on a TTY, and thus unable to display on the fringes.
8937 That's because the text with the property will not be displayed anyway,
8938 so we need to signal to the caller that this is a "replacing"
8939 display spec. This fixes display when the spec is invalid or we
8942 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
8944 * unexaix.c (make_hdr): Fix typo in prototype.
8945 This bug broke the build on AIX. Problem reported by Gilles Pion.
8947 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
8949 * keyboard.c (kbd_buffer_get_event): Read special events also in
8950 batch mode. (Bug#11415)
8952 2012-05-12 Glenn Morris <rgm@gnu.org>
8954 * ns.mk: Update for ns_appbindir no longer having trailing "/".
8956 2012-05-12 Eli Zaretskii <eliz@gnu.org>
8958 * lisp.mk (lisp): Add newcomment.elc.
8960 2012-05-12 Glenn Morris <rgm@gnu.org>
8962 * Makefile.in (MKDIR_P): New, set by configure.
8963 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
8965 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
8967 Remove unused function hourglass_started.
8968 * dispextern.h (hourglass_started):
8969 * w32fns.c (hourglass_started):
8970 * xdisp.c (hourglass_started): Remove.
8972 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
8974 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
8975 Update dependencies.
8977 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
8979 * xgselect.c (xg_select): Put maxfds+1 into a var.
8980 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
8982 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
8984 2012-05-10 Dave Abrahams <dave@boostpro.com>
8986 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
8987 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
8989 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
8991 * dbusbind.c (xd_registered_buses): New internal Lisp object.
8992 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
8993 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
8994 Initialize xd_registered_buses.
8996 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
8998 Untag more efficiently if USE_LSB_TAG.
8999 This is based on a proposal by YAMAMOTO Mitsuharu in
9000 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
9001 For an admittedly artificial (nth 8000 longlist) benchmark on
9002 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
9003 Emacs's overall text size by 1%.
9004 * lisp.h (XUNTAG): New macro.
9005 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
9006 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
9007 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
9008 * eval.c (Fautoload):
9009 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
9010 * frame.h (XFRAME): Use XUNTAG.
9012 Port recent dbusbind.c changes to 32-bit --with-wide-int.
9013 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
9014 Remove unportable assumptions about print widths of types like
9016 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
9017 intptr_t when converting between pointer and integer, to avoid GCC
9018 warnings about wrong width.
9020 2012-05-09 Eli Zaretskii <eliz@gnu.org>
9022 * w32proc.c (new_child): Force Windows to reserve only 64KB of
9023 stack for each reader_thread, instead of defaulting to 8MB
9024 determined by the linker. This avoids failures in creating
9025 subprocesses on Windows 7, see the discussion in this thread:
9026 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
9028 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
9030 Fix up display of the *Minibuf-0* buffer in the mini window.
9031 * keyboard.c (read_char): Don't clear the echo area if there's no
9033 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
9034 contents of *Minibuf-0*) if there's no message displayed in its stead.
9036 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
9038 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
9041 2012-05-06 Chong Yidong <cyd@gnu.org>
9043 * lisp.mk (lisp): Update.
9045 2012-05-05 Jim Meyering <meyering@redhat.com>
9047 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
9049 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
9051 * data.c (PUT_ERROR): New macro.
9052 (syms_of_data): Use it. Add new error type `user-error'.
9053 * undo.c (user_error): New function.
9054 (Fprimitive_undo): Use it.
9055 * print.c (print_error_message): Adjust print style for `user-error'.
9056 * keyboard.c (user_error): New function.
9057 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
9059 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
9061 Do not limit current-time-string to years 1000..9999.
9062 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
9063 (Fcurrent_time_string): Support any year that is supported by the
9064 underlying localtime representation. Don't use asctime, as it
9065 has undefined behavior for years outside the range -999..9999.
9067 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
9069 Fix race conditions involving setenv, gmtime, localtime, asctime.
9070 Without this fix, interrupts could mess up code that uses these
9071 nonreentrant functions, since setting TZ invalidates existing
9072 tm_zone or tzname values, and since most of these functions return
9073 pointers to static storage.
9074 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
9075 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
9076 Grow the critical sections to include not just invoking
9077 localtime/gmtime, but also accessing these functions' results
9078 including their tm_zone values if any, and any related TZ setting.
9079 (format_time_string): Last arg is now struct tm *, not struct tm **,
9080 so that the struct tm is saved in the critical section.
9081 All callers changed. Simplify allocation of initial buffer, partly
9082 motivated by the fact that memory allocation needs to be outside
9083 the critical section.
9085 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
9087 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
9088 with RESET_INTERVAL.
9090 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
9091 Remove duplicated buffer name initialization.
9093 2012-05-02 Jim Meyering <jim@meyering.net>
9095 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
9097 * xfns.c (x_window): Use xstrdup (Bug#11375).
9099 2012-05-02 Eli Zaretskii <eliz@gnu.org>
9101 * xdisp.c (pos_visible_p): If already at a newline from the
9102 display string before the 'while' loop, don't walk back the glyphs
9103 from it3.glyph_row. Solves assertion violation when the display
9104 string begins with a newline (egg.el). (Bug#11367)
9106 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
9108 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
9111 2012-05-01 Glenn Morris <rgm@gnu.org>
9113 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
9114 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
9115 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
9116 All were removed before 23.1.
9118 * dispnew.c: Remove HAVE_LIBNCURSES test;
9119 it is always true on relevant platforms.
9121 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
9122 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
9124 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
9126 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
9128 * .gdbinit (xpr): Remove checks for no longer existing misc types.
9129 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
9132 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
9134 Do not avoid creating empty evaporating overlays (Bug#9642).
9135 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
9136 That is, do not delete an evaporating overlay if it becomes
9137 empty after its bounds are adjusted to fit within its buffer.
9138 This fix caused other problems, and I'm reverting it until we get
9139 to the bottom of them.
9141 2012-04-27 Chong Yidong <cyd@gnu.org>
9143 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
9145 2012-04-27 Eli Zaretskii <eliz@gnu.org>
9147 * xdisp.c (pos_visible_p): If the window start position is beyond
9148 ZV, start the display from buffer beginning. Prevents assertion
9149 violation in init_iterator when the minibuffer window is scrolled
9152 * window.c (window_scroll_pixel_based): Likewise.
9154 2012-04-27 Chong Yidong <cyd@gnu.org>
9156 * keymap.c (where_is_internal): Doc fix (Bug#10872).
9158 2012-04-27 Glenn Morris <rgm@gnu.org>
9160 * fileio.c (Fcopy_file, Fset_file_selinux_context):
9161 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
9163 2012-04-27 Eli Zaretskii <eliz@gnu.org>
9165 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
9166 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
9168 2012-04-26 Eli Zaretskii <eliz@gnu.org>
9170 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
9171 display element, check also the underlying string or buffer
9172 character. (Bug#11341)
9174 * w32menu.c: Include w32heap.h.
9175 (add_menu_item): If the call to AppendMenuW (via
9176 unicode_append_menu) fails, disable Unicode menus only if we are
9177 running on Windows 9X/Me.
9179 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
9181 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
9182 (xgetint): Add missing shift for LSB tags.
9184 2012-04-24 Martin Rudalics <rudalics@gmx.at>
9186 * keyboard.c (read_char): Don't wipe echo area for select window
9187 events: These might get delayed via `mouse-autoselect-window'
9190 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
9192 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
9193 manipulation of :loaded-from data.
9195 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
9197 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
9198 now a cons (bug#11311).
9200 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
9202 Do not create empty overlays with the evaporate property (Bug#9642).
9203 * buffer.c (Fmove_overlay): Delete an evaporating overlay
9204 if it becomes empty after its bounds are adjusted to fit within
9205 its buffer. Without this fix, in a nonempty buffer (let ((o
9206 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
9207 yields an empty overlay that has the evaporate property, which is
9208 not supposed to happen.
9210 Fix minor GTK3 problems found by static checking.
9211 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
9212 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
9213 (struct _EmacsFixedClass, emacs_fixed_get_type):
9214 Move decls here from emacsgtkfixed.h, since they needn't be public.

9216 (emacs_fixed_class_init): Omit unused local.
9217 (emacs_fixed_child_type): Remove; unused.

9219 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
9220 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
9221 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
9222 (EMACS_FIXED_GET_CLASS): Remove; unused.
9223 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
9225 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
9226 Problem reported by Juanma Barranquero for Windows -Wunused-function.
9228 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
9230 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
9231 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
9232 (__malloc_size_t, __malloc_ptrdiff_t):
9233 Remove. All uses removed, replaced by the definiens if needed,
9234 since we can assume C89 or better now.
9235 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
9236 (protect_malloc_state, align, get_contiguous_space)
9237 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)

9243 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
9244 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
9245 Define using prototypes, not old style.
9246 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
9247 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
9248 (align): Don't assume that signed integer overflow wraps around.
9249 Omit unused local var.
9250 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
9251 (_free_internal_nolock, memalign, mallochook, reallochook):
9252 Omit no-longer-needed casts.
9253 (valloc): Use getpagesize, not __getpagesize.
9254 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
9255 (struct hdr): The 'magic' member is now size_t, not unsigned long.
9257 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
9259 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
9261 Move functions from C to Lisp. Make non-blocking method calls
9262 the default. Implement further D-Bus standard interfaces.
9264 * dbusbind.c (DBUS_NUM_MESSAGE_TYPES): Declare.
9265 (QCdbus_request_name_allow_replacement)
9266 (QCdbus_request_name_replace_existing)

9304 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
9306 Fix GC_MALLOC_CHECK debugging output on 64-bit hosts.
9307 * alloc.c (emacs_blocked_malloc) [GC_MALLOC_CHECK]:
9308 Do not assume ptrdiff_t is the same width as 'int'.
9310 * alloc.c: Handle unusual debugging option combinations.
9311 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
9312 since the two debugging options are incompatible.
9313 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
9315 (mem_init, mem_insert, mem_insert_fixup):
9316 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

9346 * print.c (print_preprocess): Only check print_depth if print-circle
9348 (print_object): Check for cycles even when print-circle is nil and
9349 print-gensym is t, but only check print_depth if print-circle is nil.
9351 2012-04-20 Chong Yidong <cyd@gnu.org>
9353 * process.c (wait_reading_process_output): If EIO occurs on a pty,
9354 set the status to "failed" and ensure that sentinel is run.

9369 farther than the first row after the header line, if any.
9370 Don't consider the header-line row as "partially visible", even if
9371 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)
9373 2012-04-20 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

9408 * alloc.c (_malloc_internal, _free_internal) [!DOUG_LEA_MALLOC]:
9409 New extern decls, to avoid calling undeclared functions.
9410 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
9411 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
9412 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
9413 (NEED_MEM_INSERT): New macro.
9414 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
9415 Remove one incorrect comment and fix another.

9429 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
9430 Remove decls. This fixes an "It stinks!".

9434 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
9436 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

9451 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
9452 * s/netbsd.h, s/sol2-6.h:
9453 Remove definition of GC_MARK_STACK, since the default now works.
9454 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
9455 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
9456 no longer the default.
9457 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
9459 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
9461 * lread.c (lisp_file_lexically_bound_p):

9482 2012-04-11 Daniel Colascione <dancol@dancol.org>
9484 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
9485 against is gone. It's better to use vfork now so that when Cygwin
9486 gains a new, working vfork, we use it automatically (bug#10398).
9488 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

9508 * w32.c (w32_delayed_load): Record the full path of the library
9509 being loaded (bug#10424).
9511 2012-04-09 Glenn Morris <rgm@gnu.org>
9513 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
9514 not just in the obarray, before snarfing them. (Bug#11036)
9516 * Makefile.in ($(leimdir)/leim-list.el):
9517 Pass EMACS rather than BUILT_EMACS.

9526 Add convenience `GNUTLS_LOG2i' macro.
9528 * gnutls.c (gnutls_log_function2i): Convenience log function.
9529 (emacs_gnutls_read): Use new log functions,
9530 `gnutls_handshakes_tried' process member, and

9541 * minibuf.c (Fread_variable): Callers changed.
9543 2012-04-09 Eli Zaretskii <eliz@gnu.org>
9545 * xdisp.c (set_cursor_from_row): If the display string appears in
9546 the buffer at position that is closer to point than the position
9547 after the display string, display the cursor on the first glyph of
9548 the display string. Fixes cursor display when a 'display' text
9549 property immediately follows invisible text. (Bug#11094)
9551 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
9553 composite.c: use 'double' consistently
9554 * composite.c (get_composition_id): Use 'double' consistently
9555 instead of converting 'float' to 'double' and vice versa; this is
9556 easier to understand and avoids a GCC warning.
9558 2012-04-09 Glenn Morris <rgm@gnu.org>
9560 * Makefile.in: Generate leim-list with bootstrap-emacs, in
9561 preparation for dumping it with emacs. (Bug#4789)

9583 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
9584 (mark_memory): Mark Lisp_Objects only if pointers might hide in
9585 objects, as mark_maybe_pointer will catch them otherwise.
9586 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
9587 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.

9591 Fix typo that broke non-Windows builds.
9592 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.

9603 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
9604 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
9605 [!WINDOWSNT]: New macros.
9606 (init_libxml2_functions, libxml2_loaded_p): New functions.
9607 (parse_region): Call fn_xmlCheckVersion instead of using the macro
9608 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
9609 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
9610 Calls xmlCleanupParser only if libxml2 was loaded (or statically
9612 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
9613 Call init_libxml2_functions before calling libxml2 functions.
9614 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
9616 * emacs.c: Don't include libxml/parser.h.
9617 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
9618 xmlCleanupParser directly.
9620 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
9622 2012-04-07 Eli Zaretskii <eliz@gnu.org>
9624 * indent.c (Fvertical_motion): If there is a display string at
9625 point, use it.vpos to compute how many lines to backtrack after

9630 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
9631 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
9632 about subtle differences between FETCH_CHAR* and STRING_CHAR*
9633 macros related to unification of CJK characters. For the details,
9634 see the discussion following the message here:
9635 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
9637 2012-04-04 Chong Yidong <cyd@gnu.org>
9639 * keyboard.c (Vdelayed_warnings_list): Doc fix.
9641 2012-04-01 Eli Zaretskii <eliz@gnu.org>
9643 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA

9651 2012-03-31 Eli Zaretskii <eliz@gnu.org>
9653 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
9654 position we get to after a call to move_it_to fails the
9655 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
9656 only if we wind up in a string from display property. (Bug#11063)
9658 * window.c (Fdelete_other_windows_internal): Invalidate the row
9659 and column information about mouse highlight, so that redisplay
9660 restores it after reallocating the glyph matrices. (Bug#7464)
9662 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
9663 string comes from a `display' text property, use the buffer
9664 position of that property as if we actually saw that position in
9666 (move_it_by_lines): Remove the assertion that
9667 "it->current_x == 0 && it->hpos == 0" which can be legitimately
9668 violated when there's a before-string at the beginning of a line.
9671 2012-03-30 Eli Zaretskii <eliz@gnu.org>
9673 * xdisp.c (append_space_for_newline): If the default face was
9674 remapped, use the remapped face for the appended newline.
9675 (extend_face_to_end_of_line): Use the remapped default face for
9676 extending the face to the end of the line.
9677 (display_line): Call extend_face_to_end_of_line when the default
9678 face was remapped. (Bug#11068)
9680 2012-03-29 Eli Zaretskii <eliz@gnu.org>

9702 handle-select-window too (Bug#8996).
9704 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
9706 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
9708 2012-03-25 Kenichi Handa <handa@m17n.org>
9710 * dispextern.h (struct glyph): Change the bit length of
9711 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
9713 2012-03-24 Eli Zaretskii <eliz@gnu.org>
9715 * s/ms-w32.h (tzname): Include time.h before redirecting to
9716 _tzname. Fixes the MSVC build. (Bug#9960)

9720 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
9723 * xterm.c (XTread_socket): Only modify handling_signal if

9726 2012-03-23 Eli Zaretskii <eliz@gnu.org>
9728 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
9729 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
9730 when fetching a multibyte character consumes more bytes than
9731 CHAR_BYTES returns, due to unification of CJK characters in
9732 string_char. (Bug#11073)
9734 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
9736 * process.c (wait_reading_process_output): Handle pty disconnect
9737 by refraining from sending oneself a SIGCHLD (bug#10933).

9748 2012-03-21 Chong Yidong <cyd@gnu.org>
9750 * xfaces.c (Vface_remapping_alist): Doc fix.
9752 2012-03-20 Eli Zaretskii <eliz@gnu.org>
9754 * w32proc.c (Fw32_set_console_codepage)
9755 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):

9760 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
9761 to reflect default non-nil value of redisplay-dont-pause.

9766 it fit in a valid range (Bug#11003).
9768 2012-03-18 Eli Zaretskii <eliz@gnu.org>
9770 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
9771 that is not from display property, accept the row as a "cursor
9772 row" if one of the string's character has a non-nil `cursor'
9773 property. Fixes cursor positioning when there are newlines in
9774 overlay strings, e.g. in icomplete.el. (Bug#11035)
9776 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
9778 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
9780 2012-03-12 Chong Yidong <cyd@gnu.org>
9782 * eval.c (inhibit_lisp_code): Rename from
9783 inhibit_window_configuration_change_hook; move from window.c.
9785 * xfns.c (unwind_create_frame_1, Fx_create_frame):
9786 * window.c (run_window_configuration_change_hook)
9787 (syms_of_window): Callers changed.
9789 2012-03-11 Chong Yidong <cyd@gnu.org>
9791 * keymap.c (Fkey_description): Doc fix (Bug#9700).

9806 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
9807 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
9810 2012-03-03 Glenn Morris <rgm@gnu.org>
9812 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.

9825 * buffer.c (buffer-list-update-hook): Doc fix.
9827 2012-02-29 Eli Zaretskii <eliz@gnu.org>

9830 push_it before setting up the iterator for the first overlay
9831 string, even if we have an empty string loaded.
9832 (next_overlay_string): If there's an empty string on the iterator
9833 stack, pop the stack. (Bug#10903)
9835 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
9837 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
9838 Suggested by Stefan Monnier in
9839 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
9840 * alloc.c (widen_to_Lisp_Object): New static function.
9841 (mark_memory): Also mark Lisp_Objects by fetching pointer words
9842 and widening them to Lisp_Objects. This would work even if
9843 USE_LSB_TAG is defined and wide integers are used, which might
9844 happen in a future version of Emacs.
9846 2012-02-25 Chong Yidong <cyd@gnu.org>
9848 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):

9852 (x_clipboard_manager_save_all): Print an informative message
9853 before saving to clipboard manager.

9863 call when setting menu-bar-lines and tool-bar-lines parameters.
9864 (unwind_create_frame_1): New helper function.
9866 * window.c (inhibit_window_configuration_change_hook): New var.
9867 (run_window_configuration_change_hook): Obey it.

9885 when computing $valmask.
9887 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
9888 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
9889 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
9890 It's useless in that case, and it can cause problems on hosts
9891 that allocate halves of EMACS_INT values separately.
9892 Reported by Dan Horák. Diagnosed by Andreas Schwab in
9893 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
9894 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
9895 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
9896 it avoids undefined behavior on hosts where shifting right by more
9897 than the word width has undefined behavior.
9899 2012-02-19 Chong Yidong <cyd@gnu.org>
9901 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
9902 (Funhandled_file_name_directory, Ffile_name_as_directory)

9942 as that creates a dangerous corner case.
9944 * window.c (Fdelete_window_internal): Invalidate the mouse
9945 highlight (Bug#9904).
9947 2012-02-12 Glenn Morris <rgm@gnu.org>

9979 * buffer.c (Fbuffer_local_variables)
9980 (buffer_lisp_local_variables): Handle unbound vars correctly;
9981 don't let Qunbound leak into Lisp.
9983 2012-02-07 Glenn Morris <rgm@gnu.org>
9985 * image.c (Fimagemagick_types): Doc fix.
9987 * image.c (imagemagick-render-type): Change it from a lisp object
9988 to an integer. Move the doc here from the lisp manual.

10022 Handle overflow when computing char display width (Bug#9496).
10023 * character.c (char_width): Return EMACS_INT, not int.
10024 (char_width, c_string_width): Check for overflow when
10025 computing the width; this is possible now that individual
10026 characters can have unbounded width. Problem introduced
10027 by merge from Emacs 23 on 2012-01-19.

10051 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
10053 (x_produce_glyphs): If the component of a composition is a null

10058 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
10059 first 2 arguments are identical. This makes inserting large
10060 output from a subprocess an order of magnitude faster on

10169 (Fmake_directory_internal): Use it.
10170 (do_auto_save_make_dir): Set it, instead of invoking chmod after

10514 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
10515 verifies glyph row's hash code--we have just reallocated the

10681 is set, removing the need for VIRT_ADDRESS_VARIES.
10682 (PURE_P): Use a more-efficient implementation that needs just one

10699 behave as if the cursor position were at the window margin.
10701 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
10702 and the cursor position is out of bounds, behave as if the cursor
10703 position were at the window margin. (Bug#10075)
10705 2011-11-18 Chong Yidong <cyd@gnu.org>
10707 * window.c (Fwindow_combination_limit): Make first argument

10729 compute_line_metrics.
10730 (compute_line_metrics): Call row_hash, instead of computing the
10733 * dispnew.c (verify_row_hash): Call row_hash for computing the
10734 hash code of a row, instead of duplicating code from xdisp.c.
10736 * dispextern.h (row_hash): Add prototype.
10738 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
10740 * frame.c (delete_frame): Don't delete the terminal when the last

10923 Otherwise, these inline functions do not conform to C99 and
10924 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
10925 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
10926 * intervals.c (adjust_intervals_for_insertion)

10929 (static_offset_intervals): Remove.
10930 (offset_intervals): Rewrite using the old contents of
10931 static_offset_intervals. The old version didn't conform to C99
10932 because an extern inline function contained a reference to an
10933 identifier with static linkage.

11210 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
11212 * w32fns.c (w32_default_color_map): New function,
11213 extracted from Fw32_default_color_map.
11214 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
11216 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
11218 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
11220 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
11222 * keyboard.c (test_undefined): New function (bug#9751).
11223 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
11225 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
11227 * sysdep.c (init_sys_modes): Fix the check for the controlling
11228 terminal (Bug#6649).
11230 2011-10-20 Eli Zaretskii <eliz@gnu.org>
11232 * dispextern.h (struct bidi_it): New member next_en_type.
11234 * bidi.c (bidi_line_init): Initialize the next_en_type member.
11235 (bidi_resolve_explicit_1): When next_en_pos is valid for the
11236 current character, check also for next_en_type being WEAK_EN.
11237 (bidi_resolve_weak): Don't enter the expensive loop if the current
11238 position is before next_en_pos. Record the bidi type of the first
11239 non-ET, non-BN character we find, in addition to its position.
11240 (bidi_level_of_next_char): Invalidate next_en_type when
11241 next_en_pos is over-stepped.
11243 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
11245 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
11246 * editfns.c: Rewrite current-time-zone so that it invokes
11247 the equivalent of (format-time-string "%Z") to get the time zone name.
11248 This fixes a bug when the time zone name contains characters that
11249 need converting from the system time locale to Emacs internal format.
11250 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
11251 that patch fixed format-time-string to do the conversion, but
11252 I forgot to fix current-time-zone.
11253 (format_time_string): New function, containing most of
11254 what Fformat_time_string used to contain.
11255 (Fformat_time_string): Rewrite in terms of format_time_string.
11256 This doesn't change this function's behavior.
11257 (current-time-zone): Rewrite to use format_time_string.
11258 This fixes the bug reported by Michael Schierl in
11259 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
11260 Jason Rumney's 2007-06-07 change worked around this bug, but
11262 * systime.h (tzname, timezone): Remove no-longer-used declarations.
11264 2011-10-19 Eli Zaretskii <eliz@gnu.org>
11266 * xdisp.c (start_display): If the character at POS is displayed
11267 via a display vector, reset IT->current.dpvec_index to zero.
11268 (try_window_reusing_current_matrix): If a line ends in a display
11269 vector or the next line starts in a display vector, continue
11270 redrawing the window even though the character position of
11271 start_row was reached.
11274 2011-10-18 Chong Yidong <cyd@gnu.org>
11276 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
11277 with nobreak-char-display too.
11279 2011-10-18 Eli Zaretskii <eliz@gnu.org>
11281 Fix part 3 of bug#9771.
11282 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
11283 (bidi_resolve_neutral): Don't enter the expensive loop looking for
11284 non-neutral characters if the current character is a paragraph
11285 separator (a.k.a. Newline). This avoids running the same
11286 expensive loop twice, once when we consume the preceding newline
11287 and the other time when the line actually needs to be displayed.
11288 Avoid the loop when we see neutrals on the base embedding level
11289 following a character whose directionality is the same as the
11290 paragraph's. This avoids running the expensive loop when a line
11291 ends in a long sequence of neutrals, like control characters.
11292 Add assertion against STRONG_AL type. Slightly rearrange code
11293 that determines the type of a neutral given the first non-neutral
11295 (bidi_level_of_next_char): Set next_en_pos to zero when
11296 invalidating its info.
11298 2011-10-17 Eli Zaretskii <eliz@gnu.org>
11300 * xdisp.c (push_display_prop): Determine whether to record string
11301 or buffer position by IT->string, not by IT->method. Allow
11302 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
11303 (move_it_vertically_backward): Don't look for character position
11304 immediately after the newline when in a continuation line.
11307 2011-10-15 Martin Rudalics <rudalics@gmx.at>
11309 * window.c (coordinates_in_window): Rewrite and delabelize
11310 vertical border check. (Bug#5357) (Bug#9618)
11312 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
11314 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
11315 errors in XSetWindowBorder (bug#9310).
11317 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
11319 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
11320 avoid crash when xmalloc overrun checking is enabled.
11322 2011-10-13 Eli Zaretskii <eliz@gnu.org>
11324 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
11325 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
11326 cursor motion with <left> and <right> arrow keys.
11328 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
11329 some callers set that themselves.
11331 2011-10-12 Eli Zaretskii <eliz@gnu.org>
11333 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
11334 display string and the previous row comes from the same string and
11335 is empty. (Bug#9739) (Bug#9738)
11337 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
11339 * doc.c (get_doc_string): Encode file name (bug#9735).
11341 2011-10-12 Eli Zaretskii <eliz@gnu.org>
11343 * bidi.c (bidi_level_of_next_char):
11344 * xdisp.c (get_visually_first_element): Remove old incorrect
11345 comments regarding the Unicode Line Separator character.
11347 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
11349 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
11351 * alloc.c (Fgc_status): Do not access beyond zombies array
11352 boundary if nzombies > MAX_ZOMBIES.
11353 * alloc.c (dump_zombies): Add missing format specifier.
11355 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
11357 * xdisp.c (set_cursor_from_row): Simplify conditionals,
11358 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
11360 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
11361 Some packages use them to denote characters with modifiers.
11363 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
11365 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
11366 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
11367 matching a pp-number. Rename parameter var to var1.
11369 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
11371 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
11373 2011-10-08 Glenn Morris <rgm@gnu.org>
11375 * callint.c (Fcall_interactively): Give a more explicit error for the
11376 'c' case with a non-character input. (Bug#8479)
11378 2011-10-08 Eli Zaretskii <eliz@gnu.org>
11380 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
11382 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
11383 lines that are hscrolled on the left.
11385 * dispnew.c (buffer_posn_from_coords): Account for a possible
11386 presence of header-line. (Bug#4426)
11388 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
11390 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
11391 Don't advertise functionality which we discourage or doesn't work.
11393 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
11395 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
11396 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
11397 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
11398 this makes Emacs dump core during garbage collection on rare
11399 occasions. sizeof is obviously inferior to offsetof here, so
11400 stick with offsetof.
11401 (GC_POINTER_ALIGNMENT): New macro.
11402 (mark_memory): Omit 3rd (offset) arg; caller changed.
11403 Don't assume EMACS_INT alignment is the same as pointer alignment.
11405 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
11407 * keyboard.c (read_key_sequence_remapped): New var.
11408 (read_key_sequence): Compute remapping in the right buffer.
11409 (command_loop_1): Use read_key_sequence's remapping directly.
11411 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
11413 * dired.c (file_name_completion): Don't expand file name.
11414 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
11415 before checking file name handler.
11417 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
11418 they've been requested explicitly (bug#9591).
11420 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
11422 * keymap.c (Fsingle_key_description): Use make_specified_string
11423 instead of build_string to build string from push_key_description.
11426 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
11428 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
11429 This fixes a Y2038 bug on 64-bit hosts.
11430 * buffer.c (reset_buffer):
11431 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
11432 (Fclear_buffer_auto_save_failure):
11433 Use 0, not -1, to represent an unset failure time, since time_t
11434 might not be signed.
11436 Remove dependency on glibc malloc internals.
11437 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11438 Move back here from lisp.h, but with their new implementations.
11439 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
11440 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
11441 * charset.c (charset_table_init): New static var.
11442 (syms_of_charset): Use it instead of xmalloc. This removes a
11443 dependency on glibc malloc internals. See Eli Zaretskii's comment in
11444 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
11445 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11446 Move back to alloc.c.
11447 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
11448 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
11450 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
11452 * nsterm.m (windowDidResize): Call x_set_window_size only when
11453 ns_in_resize is true. Otherwise set pixelwidth/height and
11454 call change_frame_size (Bug#9628).
11456 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
11458 Port --enable-checking=all to Fedora 14 x86-64.
11459 * charset.c (syms_of_charset): Also account for glibc malloc's
11460 internal overhead when calculating the initial malloc maximum.
11462 Port --enable-checking=all to Fedora 14 x86.
11463 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11465 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
11466 (overrun_check_realloc, overrun_check_free):
11467 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
11468 That way, xmalloc returns a properly-aligned pointer even if
11469 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
11470 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
11471 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
11472 into account when calculating the initial malloc maximum.
11473 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11474 Move here from alloc.c, so that charset.c can use it too.
11475 Properly align; the old code wasn't right for common 32-bit hosts
11476 when configured with --enable-checking=all.
11477 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
11478 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
11480 2011-09-29 Eli Zaretskii <eliz@gnu.org>
11482 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
11485 2011-09-28 Eli Zaretskii <eliz@gnu.org>
11487 * xdisp.c (compute_display_string_end): If there's no display
11488 string at CHARPOS, return -1.
11490 * bidi.c (bidi_fetch_char): When compute_display_string_end
11491 returns a negative value, treat the character as a normal
11492 character not covered by a display string. (Bug#9624)
11494 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
11496 * lread.c (Fread_from_string): Fix typo in docstring.
11498 2011-09-27 Eli Zaretskii <eliz@gnu.org>
11500 * xdisp.c (handle_invisible_prop): If invisible text ends on a
11501 newline, reseat the iterator instead of bidi-iterating there one
11502 character at a time. (Bug#9610)
11503 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
11504 TO_CHARPOS if the bidi iterator is at base embedding level.
11506 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
11508 * lread.c (readevalloop): Use correct code for NBSP.
11509 (read1): Likewise. (Bug#9608)
11511 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
11513 * dbusbind.c (Fdbus_register_signal): When service is not
11514 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
11516 2011-09-25 Glenn Morris <rgm@gnu.org>
11518 * buffer.c (truncate-lines): Doc fix.
11520 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
11522 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
11523 (Fset_window_next_buffers): Doc fix.
11525 2011-09-24 Glenn Morris <rgm@gnu.org>
11527 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
11529 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
11531 Fix minor problems found by static checking.
11532 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
11533 * indent.c (Fvertical_motion): Fix == vs = typo.
11535 2011-09-24 Eli Zaretskii <eliz@gnu.org>
11537 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
11538 Default value is now t. Doc fix.
11540 * indent.c (Fvertical_motion): Compute and apply the overshoot
11541 logic when moving up, not only when moving down. Fix the
11542 confusing name and values of the it_overshoot_expected variable;
11543 logic changes accordingly. (Bug#9254) (Bug#9549)
11545 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
11546 CHARPOS is covered by a display string which includes newlines.
11547 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
11548 is covered by a display string with embedded newlines.
11550 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
11552 * dbusbind.c (Fdbus_register_signal): Add match rule to
11553 Vdbus_registered_objects_table. (Bug#9581)
11554 (Fdbus_register_method, Vdbus_registered_objects_table):
11557 2011-09-24 Jim Meyering <meyering@redhat.com>
11559 do not ignore write error for any output size
11560 The previous change was incomplete.
11561 While it makes emacs --batch detect the vast majority of stdout
11562 write failures, errors were still ignored whenever the output size is
11563 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
11564 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
11565 && echo FAIL: ignored write error
11566 FAIL: ignored write error
11567 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
11568 && echo FAIL: ignored write error
11569 FAIL: ignored write error
11570 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
11572 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
11574 * emacs.c (Fkill_emacs): In noninteractive mode exit
11575 non-successfully if a write error occurred on stdout. (Bug#9574)
11577 2011-09-21 Eli Zaretskii <eliz@gnu.org>
11579 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
11582 * dispextern.h (struct it): Update the comment documenting what
11585 2011-09-20 Eli Zaretskii <eliz@gnu.org>
11587 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
11588 a display string, extend search for cursor position to end of row.
11589 (find_row_edges): If the row ends in a newline from a display
11590 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
11591 Handle the case of a display string with multiple newlines.
11592 (Fcurrent_bidi_paragraph_direction): Fix search for previous
11593 non-empty line. Fixes confusing cursor motion with arrow keys at
11594 the beginning of a line that starts with whitespace.
11596 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
11598 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
11601 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
11603 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
11604 boolean (Bug#9154).
11606 2011-09-18 Eli Zaretskii <eliz@gnu.org>
11608 * xdisp.c (display_line): Record maximum and minimum buffer
11609 positions even if no glyphs were produced (e.g., by a zero-width
11610 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
11611 buffer positions that will be removed from the glyph row because
11613 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
11614 column is beyond frame width: don't subtract 1 "pixel" when
11615 computing width of the stretch.
11616 (reseat_at_next_visible_line_start): Undo the change made on
11617 2011-09-17 that saved paragraph information and restored it after
11618 the call to `reseat'. (Bug#9545)
11620 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11622 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
11623 and turn window cursor on if cleared (Bug#9415).
11625 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
11627 * search.c (boyer_moore): Take unibyte characters from pattern
11628 literally. (Bug#9458)
11630 2011-09-18 Eli Zaretskii <eliz@gnu.org>
11632 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
11634 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
11636 Fix minor problem found by static checking.
11637 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
11638 initialized, to pacify gcc -Wuninitialized.
11640 * fileio.c: Report proper errno when syscall falls.
11641 (Finsert_file_contents): Save and restore errno,
11642 so that report_file_error outputs the correct diagnostic.
11643 (Fwrite_region) [CLASH_DETECTION]: Likewise.
11645 2011-09-18 Eli Zaretskii <eliz@gnu.org>
11647 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
11649 2011-09-17 Eli Zaretskii <eliz@gnu.org>
11651 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
11652 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
11654 2011-09-17 Eli Zaretskii <eliz@gnu.org>
11656 * xdisp.c (reseat_at_next_visible_line_start): Keep information
11657 about the current paragraph and restore it after the call to reseat.
11659 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
11660 (bidi_find_paragraph_start): Search back for paragraph beginning
11661 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
11662 (bidi_move_to_visually_next): Only trigger paragraph-related
11663 computations when the last character is a newline or at EOB, not
11664 just any NEUTRAL_B. (Bug#9470)
11666 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
11667 truncated lines if point is covered by a display string. (Bug#9524)
11669 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
11671 * xselect.c: Relax test for outgoing X longs (Bug#9498).
11672 (cons_to_x_long): New function.
11673 (lisp_data_to_selection_data): Use it. Correct the test for
11674 short-versus-long data; it was negated. Break out of vector
11675 loop, for efficiency, when a long datum is discovered.
11677 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
11679 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
11681 2011-09-16 Eli Zaretskii <eliz@gnu.org>
11683 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
11684 GCC PR/17406) by declaring this function with external scope.
11686 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
11688 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
11689 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
11691 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
11693 * editfns.c (Fformat): Correctly handle text properties on "%%".
11695 2011-09-15 Eli Zaretskii <eliz@gnu.org>
11697 * xterm.c (x_draw_composite_glyph_string_foreground):
11698 * w32term.c (x_draw_composite_glyph_string_foreground):
11699 * term.c (encode_terminal_code):
11700 * composite.c (composition_update_it, get_composition_id):
11701 * xdisp.c (get_next_display_element)
11702 (fill_composite_glyph_string): Add comments about special meaning
11703 of TAB characters in a composition.
11705 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
11707 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
11708 This occurs when processing a multibyte format.
11709 Problem reported by Wolfgang Jenker.
11711 2011-09-15 Johan Bockgård <bojohan@gnu.org>
11713 * xdisp.c (try_cursor_movement): Only check for exact match if
11714 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
11716 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
11718 Remove unused external symbols.
11719 * dispextern.h (calc_pixel_width_or_height): Remove decl.
11720 * xdisp.c (calc_pixel_width_or_height): Now static.
11721 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
11722 * indent.c (check_display_width):
11723 * w32term.c: Fix comment to match code.
11724 * xterm.c, xterm.h (x_catching_errors): Remove.
11726 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
11728 * xselect.c: Use signed conversions more consistently (Bug#9498).
11729 (selection_data_to_lisp_data): Assume incoming selection data are
11730 signed integers, not unsigned. This is to be consistent with
11731 outgoing selection data, which was modified to use signed integers
11732 in as part of the fix to Bug#9196 in response to Jan D.'s comment
11733 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
11734 expects long, not unsigned long.
11736 2011-09-14 Eli Zaretskii <eliz@gnu.org>
11738 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
11739 computation of loop end. Reported by Johan Bockgård
11742 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
11744 * frame.c (Fother_visible_frames_p): Function deleted.
11746 2011-09-12 Eli Zaretskii <eliz@gnu.org>
11748 * indent.c (compute_motion): Process display vector front to back
11749 rather than the other way around. (Bug#2496)
11751 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
11753 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
11755 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
11757 * minibuf.c (Fread_from_minibuffer): Doc fix.
11759 2011-09-11 Eli Zaretskii <eliz@gnu.org>
11761 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
11762 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
11764 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
11766 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
11767 value for non-existent files.
11769 2011-09-11 Eli Zaretskii <eliz@gnu.org>
11771 * fileio.c (Finsert_file_contents): If the file cannot be opened,
11772 set its "size" to -1. This will set the modtime_size field of
11773 the corresponding buffer to -1, which is what
11774 verify-visited-file-modtime expects for files that do not exist.
11777 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
11779 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
11781 * lisp.h: ... from here. push_key_description is no longer
11782 defined in keyboard.c, so its declaration should not be in
11783 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
11784 logically belongs with push_key_description.
11786 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
11788 * buffer.h: Include <sys/types.h> instead of <time.h>.
11789 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
11790 Problem reported by Herbert J. Skuhra.
11792 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
11794 * xml.c (parse_region): Make the parsing work for
11795 non-comment-starting XML files again (bug#9144).
11797 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
11799 * image.c (gif_load): Fix calculation of bottom and right corner.
11802 2011-09-10 Eli Zaretskii <eliz@gnu.org>
11804 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
11805 redisplay in small windows.
11807 2011-09-09 Eli Zaretskii <eliz@gnu.org>
11809 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
11811 2011-09-08 Martin Rudalics <rudalics@gmx.at>
11813 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
11814 Operate on live windows only.
11816 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
11818 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
11820 2011-09-07 Eli Zaretskii <eliz@gnu.org>
11822 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
11823 only under bidi iteration.
11825 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
11827 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
11829 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
11831 isnan: Fix porting problem to Solaris 10 with bundled gcc.
11832 Without this fix, the command to link temacs failed due to an
11833 undefined symbol __builtin_isnan. This is because
11834 /usr/include/iso/math_c99.h #defines isnan(x) to
11835 __builtin_isnan(x), but the bundled gcc, which identifies itself
11836 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
11838 * floatfns.c (isnan): #undef, and then #define to a clone of
11840 (Fisnan): Always define, since it's always available now.
11841 (syms_of_floatfns): Always define isnan at the Lisp level.
11843 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
11845 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
11847 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
11849 * fileio.c: Fix bugs with large file offsets (Bug#9428).
11850 The previous code assumed that file offsets (off_t values) fit in
11851 EMACS_INT variables, which is not true on typical 32-bit hosts.
11852 The code messed up by falsely reporting buffer overflow in cases
11853 such as (insert-file-contents "big" nil 1 2) into an empty buffer
11854 when "big" contains more than 2**29 bytes, even though this
11855 inserts just one byte and does not overflow the buffer.
11856 (Finsert_file_contents): Store file offsets as off_t
11857 values, not as EMACS_INT values. Check for overflow when
11858 converting between EMACS_INT and off_t. When checking for
11859 buffer overflow or for overlap, take the offsets into account.
11860 Don't use EMACS_INT for small values where int suffices.
11861 When checking for overlap, fix a typo: ZV was used where
11862 ZV_BYTE was intended.
11863 (Fwrite_region): Don't assume off_t fits into 'long'.
11864 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
11866 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
11868 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
11870 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
11872 sprintf-related integer and memory overflow issues (Bug#9412).
11874 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
11875 (esprintf, exprintf, evxprintf): New functions.
11876 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
11877 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
11878 (modify_event_symbol): Do not assume that the length of
11879 name_alist_or_stem is safe to alloca and fits in int.
11880 (Fexecute_extended_command): Likewise for function name and binding.
11881 (Frecursion_depth): Wrap around reliably on integer overflow.
11882 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
11883 since some callers pass EMACS_INT values.
11884 (Fsingle_key_description): Don't crash if symbol name contains more
11885 than MAX_ALLOCA bytes.
11886 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
11887 (get_minibuffer): Arg is now EMACS_INT, not int.
11888 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
11889 (esprintf, exprintf, evxprintf): New decls.
11890 * window.h (command_loop_level, minibuf_level): Reflect API changes.
11892 * dbusbind.c (signature_cat): New function.
11893 (xd_signature, Fdbus_register_signal):
11894 Do not overrun buffer; instead, report string overflow.
11896 * dispnew.c (add_window_display_history): Don't overrun buffer.
11897 Truncate instead; this is OK since it's just a log.
11899 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
11900 even if the time zone offset is outlandishly large.
11901 Don't mishandle offset == INT_MIN.
11903 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
11904 when creating daemon; the previous buffer-overflow check was incorrect.
11906 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
11907 which has the guts of the old verror function.
11909 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
11910 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
11912 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
11913 (font_unparse_xlfd): Don't blindly alloca long strings.
11914 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
11915 fits in int, when using sprintf. Use single snprintf to count
11916 length of string rather than counting it via multiple sprintfs;
11917 that's simpler and more reliable.
11918 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
11919 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
11920 sprintf, in case result does not fit in int.
11922 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
11923 (fontset_from_font): Print it.
11925 * frame.c (tty_frame_count): Now printmax_t, not int.
11926 (make_terminal_frame, set_term_frame_name): Print it.
11927 (x_report_frame_params): In X, window IDs are unsigned long,
11928 not signed long, so print them as unsigned.
11929 (validate_x_resource_name): Check for implausibly long names,
11930 and don't assume name length fits in 'int'.
11931 (x_get_resource_string): Don't blindly alloca invocation name;
11932 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
11935 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
11936 (xg_check_special_colors, xg_set_geometry):
11937 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
11939 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
11940 Use esprintf, not sprintf, in case result does not fit in int.
11942 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
11943 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
11944 it as a large positive number.
11945 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
11946 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
11948 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
11949 in case result does not fit in int.
11951 * print.c (float_to_string): Detect width overflow more reliably.
11952 (print_object): Make sprintf buffer a bit bigger, to avoid potential
11953 buffer overrun. Don't assume list length fits in 'int'. Treat
11954 print length of 0 as 0, not as infinity; to be consistent with other
11955 uses of print length in this function. Don't overflow print length
11956 index. Don't assume hash table size fits in 'long', or that
11957 vectorlike size fits in 'unsigned long'.
11959 * process.c (make_process): Use printmax_t, not int, to format
11960 process-name gensyms.
11962 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
11964 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
11965 to avoid potential buffer overrun.
11967 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
11968 if X resource line is longer than 512 bytes.
11970 * xfns.c (x_window): Make sprintf buffer a bit bigger
11971 to avoid potential buffer overrun.
11973 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
11975 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
11977 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
11979 Integer overflow fixes for scrolling, etc.
11980 Without these, Emacs silently mishandles large integers sometimes.
11981 For example, "C-u 4294967297 M-x recenter" was treated as if
11982 it were "C-u 1 M-x recenter" on a typical 64-bit host.
11984 * xdisp.c (try_window_id): Check Emacs fixnum range before
11985 converting to 'int'.
11987 * window.c (window_scroll_line_based, Frecenter):
11988 Check that an Emacs fixnum is in range before assigning it to 'int'.
11989 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
11990 values converted from Emacs fixnums.
11991 (Frecenter): Don't wrap around a line count if it is out of 'int'
11992 range; instead, treat it as an extreme value.
11993 (Fset_window_configuration, compare_window_configurations):
11994 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
11996 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
11997 that can exceed INT_MAX. Check that EMACS_INT value is in range
11998 before assigning it to the (possibly-narrower) index.
11999 (match_limit): Don't assume that a fixnum can fit in 'int'.
12001 * print.c (print_object): Use ptrdiff_t, not int, for index that can
12004 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
12005 (Fvertical_motion): Don't wrap around LINES values that don't fit
12006 in 'int'. Instead, treat them as extreme values. This is good
12007 enough for windows, which can't have more than INT_MAX lines anyway.
12009 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
12011 * Require libxml/parser.h to avoid compilation warning.
12013 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
12015 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
12016 since this reportedly can destroy thread storage.
12018 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
12020 * syntax.c (find_defun_start): Update all cache variables if
12021 exiting early (Bug#9401).
12023 2011-08-30 Eli Zaretskii <eliz@gnu.org>
12025 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
12027 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
12028 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
12029 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
12031 * term.c (tty_append_glyph): New function.
12032 (produce_stretch_glyph): Static function and its prototype deleted.
12034 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
12037 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
12039 * image.c (parse_image_spec): Check for nonnegative, not for positive,
12040 when checking :margin (Bug#9390).
12041 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
12042 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
12043 so that the name doesn't mislead. All uses changed.
12045 2011-08-28 Johan Bockgård <bojohan@gnu.org>
12047 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
12050 2011-08-27 Eli Zaretskii <eliz@gnu.org>
12052 * xdisp.c (move_it_to): Don't bail out early when reaching
12053 position beyond to_charpos, if we are scanning backwards.
12054 (move_it_vertically_backward): When DY == 0, make sure we get to
12055 the first character in the line after the newline.
12057 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
12059 * ccl.c: Improve and simplify overflow checking (Bug#9196).
12060 (ccl_driver): Do not generate an out-of-range pointer.
12061 (Fccl_execute_on_string): Remove unnecessary check for
12062 integer overflow, noted by Stefan Monnier in
12063 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
12064 Remove a FIXME that didn't need fixing.
12065 Simplify the newly-introduced buffer reallocation code.
12067 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
12069 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
12071 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
12073 Integer and memory overflow issues (Bug#9196).
12075 * doc.c (get_doc_string): Rework so that
12076 get_doc_string_buffer_size is the actual buffer size, rather than
12077 being 1 less than the actual buffer size; this makes xpalloc more
12080 * image.c (x_allocate_bitmap_record, cache_image):
12081 * xselect.c (Fx_register_dnd_atom):
12082 Simplify previous changes by using xpalloc.
12084 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
12085 since either will do and ptrdiff_t is convenient with xpalloc.
12087 * charset.c (charset_table_size)
12088 (struct charset_sort_data.priority): Now ptrdiff_t.
12089 (charset_compare): Don't overflow if priorities differ greatly.
12090 (Fsort_charsets): Don't assume list length fits in int.
12091 Check for size-calculation overflow when allocating sort data.
12092 (syms_of_charset): Allocate an initial charset table that is
12093 just under 64 KiB, to avoid problems with glibc malloc and mmap.
12095 * cmds.c (internal_self_insert): Check for size-calculation overflow.
12097 * composite.h (struct composition.glyph_len): Now int, not unsigned.
12098 The actual value is always <= INT_MAX, and leaving it unsigned made
12099 overflow checking harder.
12101 * dispextern.h (struct glyph_matrix.rows_allocated)
12102 (struct face_cache.size): Now ptrdiff_t, for convenience in use
12103 with xpalloc. The values are still always <= INT_MAX.
12105 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
12107 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
12108 (SAFE_NALLOCA): New macro.
12110 * region-cache.c (struct boundary.pos, find_cache_boundary)
12111 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
12112 (set_cache_region, invalidate_region_cache)
12113 (revalidate_region_cache, know_region_cache, region_cache_forward)
12114 (region_cache_backward, pp_cache):
12115 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
12116 so that ptrdiff_t * can be passed to xpalloc.

12136 because xmalloc/xrealloc may not return.
12137 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
12138 now that we have proper integer overflow checking.
12139 (record_overlay_string, overlay_strings): Catch overflows when
12140 calculating size of overlay_str_buf.
12142 * callproc.c (Fcall_process): Check for size overflow when

12149 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.

12189 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
12191 * emacs.c (main): Do not reallocate argv, since there is a null at
12192 the end that can be overwritten, and this way there's no need to
12193 worry about size-calculation overflow.
12194 (sort_args): Check for size-calculation overflow.
12196 * eval.c (init_eval_once, grow_specpdl): Don't update size until

12202 Check for integer overflow.
12203 (x_set_alpha): Do not assume XINT fits in int.
12205 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
12206 This is for the members text_lines, text_cols, total_lines, total_cols,
12207 where the system imposes an 'int' limit.
12209 * fringe.c (Fdefine_fringe_bitmap):
12210 Don't update size until alloc works.

12215 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
12216 Check for size-calculation overflow.
12217 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
12218 do, as we prefer signed integers.
12219 (id_to_widget.max_size, id_to_widget.used)
12220 (xg_store_widget_in_map, xg_remove_widget_from_map)

12225 * gtkutil.h: Change prototypes to match the above.
12227 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these

12311 (Fx_change_window_property): Use ptrdiff_t, not int, to count
12312 sizes, since they can exceed INT_MAX in size. Check for size

12323 (X_LONG_MIN): New macros.
12324 Use them to make the following changes clearer.
12325 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
12326 This change doesn't affect the value now, but it may help remind
12327 future maintainers not to raise the value too much later.
12328 (SELECTION_QUANTUM): Remove, replacing with ...
12329 (selection_quantum): ... new function, which avoids overflow.
12331 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
12332 assumption that selection length fits in 'int'.

12349 Don't store size until memory allocation succeeds.
12350 (x_get_window_property): Plug memory leak on memory exhaustion.
12351 Don't double-block input; malloc is safe here. Don't assume 2**34
12352 - 4 fits in unsigned long. Add an xassert to check
12353 XGetWindowProperty overflow. Be more careful about overflow
12354 calculations, and distinguish size from memory overflow better.
12355 (receive_incremental_selection): When tracing, don't assume
12356 unsigned int is less than INT_MAX.
12357 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory

12360 in the range -65535 through -1 fit in an X unsigned short.
12361 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
12362 result parameters unless successful. Rely on cons_to_unsigned
12363 to report problems with elements; the old code wasn't right anyway.
12364 (x_check_property_data): Check for int overflow; we cannot use
12365 a wider type due to X limits.

12398 * lisp.h (hash_lookup, hash_put):
12399 * minibuf.c (Ftest_completion):
12400 Use ptrdiff_t for hash table indexes, not int (which is too
12401 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
12402 32-bit --with-wide-int hosts).
12404 * charset.c (Fdefine_charset_internal): Check for integer overflow.
12405 Add a FIXME comment about memory leaks.

12413 with outlandish widths.
12414 * character.h (sanitize_tab_width): Rename from sanitize_width,
12415 now that we have two such functions. All uses changed.

12434 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
12435 (x_send_scroll_bar_event): Likewise. Check that the size does not
12436 exceed limits imposed by XClientMessageEvent, as well as the usual
12437 ptrdiff_t and size_t limits.
12439 * keyboard.c: Overflow, signedness and related fixes.
12440 (make_lispy_movement): Use same integer type in forward decl
12441 that is used in the definition.

12443 Change bufsize argument back to int, undoing my 2011-03-30 change.
12444 We prefer signed types, and int is wide enough here.
12445 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
12446 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
12447 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
12448 length, not size_t. Use ptrdiff_t for index, not int.
12449 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
12450 possibility of integer overflow.

12478 Prefer int to unsigned where either will do.
12479 (tiff_handler): New function, combining the cores of the
12480 old tiff_error_handler and tiff_warning_handler.
12481 This function is rewritten to use vsnprintf and thereby avoid
12482 stack buffer overflows. It uses only the features of vsnprintf
12483 that are common to both POSIX and native Microsoft.
12484 (tiff_error_handler, tiff_warning_handler): Use it.
12485 (tiff_load, gif_load, imagemagick_load_image):
12486 Don't assume :index value fits in 'int'.
12487 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
12488 (imagemagick_load_image): Check that crop parameters fit into
12489 the integer types that MagickCropImage accepts. Don't assume
12490 Vimagemagick_render_type has a nonnegative value. Don't assume
12491 size_t fits in 'long'.
12492 (gs_load): Use printmax_t to print the widest integers possible.

12495 2011-08-26 Eli Zaretskii <eliz@gnu.org>
12497 * xdisp.c (redisplay_window): Don't force window start if point

12502 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
12503 the display spec is of the form `(space ...)'.
12504 (handle_display_spec): Return the value returned by
12505 handle_single_display_spec, not just 1 or zero.
12506 (handle_single_display_spec): If the display spec is of the form
12507 `(space ...)', and specifies display in the text area, return 2
12509 (try_cursor_movement): Check for the need to scroll more
12510 accurately, and prefer exact match for point under bidi.
12511 Don't advance `row' beyond the last row of the window.
12513 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
12514 into disp_prop; all users changed.

12529 buffers, return left-to-right.
12530 (set_cursor_from_row): Consider candidate row a win if its glyph
12531 represents a newline and point is on that newline. Fixes cursor
12532 positioning on the newline at EOL of R2L text within L2R
12533 paragraph, and vice versa.
12534 (try_cursor_movement): Check continued rows, in addition to
12535 continuation rows. Fixes unwarranted scroll when point enters a
12536 continued line of R2L text within an L2R paragraph, or vice versa.
12537 (cursor_row_p): Consider the case of point being equal to
12538 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
12539 from the end of a short line to the beginning of a continued line

12560 extra slot even if the purpose is char-code-property-table.
12562 2011-08-23 Eli Zaretskii <eliz@gnu.org>
12564 * xdisp.c (redisplay_window): When computing centering_position,
12565 account for the height of the header line. (Bug#8874)
12567 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
12568 instead of CHAR_TO_BYTE. Fixes a crash when a completion
12569 candidate is selected by the mouse, and that candidate has a
12570 composed character under the mouse.
12572 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
12573 coordinates reported by pos-visible-in-window-p for a composed
12574 character in column zero.
12576 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>

12584 composed buffer positions.
12586 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
12588 * image.c (gif_load): Don't assume that each subimage has the same
12589 dimensions as the base image. Handle disposal method that is
12590 "undefined" by the gif spec (Bug#9335).

12600 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
12601 from an Org mode buffer to a Speedbar frame.
12603 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
12604 a composition, take its buffer position from IT->cmp_it.charpos.
12605 Fixes cursor positioning at the beginning of a line that begins
12606 with a composed character.
12608 2011-08-18 Eli Zaretskii <eliz@gnu.org>
12610 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
12611 character bidirectional type, use STRONG_L instead. Fixes crashes
12612 in a buffer produced by `describe-categories'.
12614 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
12615 members before the level stack, so they would be saved and
12616 restored when copying iterator state. Fixes incorrect reordering
12617 around TABs covered by display properties.
12619 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
12621 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

12627 Remove unnecessary aborts (Bug#9081).
12629 2011-08-17 Eli Zaretskii <eliz@gnu.org>
12631 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
12632 has no `load' handler, try opening the file locally. (Bug#9311)
12634 2011-08-16 Ken Brown <kbrown@cornell.edu>
12636 * gmalloc.c: Expand comment.
12638 2011-08-16 Eli Zaretskii <eliz@gnu.org>

12691 * xdisp.c (move_it_in_display_line_to): Don't invoke
12692 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
12693 ppos_it. Fixes vertical cursor motion when line beginning is
12694 covered by an image. (Bug#9296)
12696 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
12698 * nsterm.h (ns_run_ascript): Declare.

12702 (ns_run_ascript): New function.
12703 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
12704 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
12705 the event loop. Get status from as_status (Bug#7276).
12707 * nsterm.m (sendEvent): If event is NSApplicationDefined and
12708 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
12709 the event loop (Bug#7276).
12711 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
12713 * gnutls.c (QCgnutls_bootprop_priority)

12735 (Fnetwork_interface_list): Allocate in increments of bytes instead
12736 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
12737 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
12739 (struct ifflag_def): notrailers is smart on OSX.
12740 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
12741 Get hardware address with getifaddrs if available.
12743 2011-08-12 Eli Zaretskii <eliz@gnu.org>
12745 * xdisp.c (iterate_out_of_display_property): xassert that
12746 IT->position is set to within IT->object's boundaries. Break from
12747 the loop as soon as EOB is reached; avoids infloops in redisplay
12748 when IT->position is set up wrongly due to some bug.
12749 Set IT->current to match the bidi iterator unconditionally.
12750 (push_display_prop): Allow GET_FROM_STRING as IT->method on
12751 entry. Force push_it to save on the stack the current
12752 buffer/string position, to be restored by pop_it. Fix flags in
12753 the iterator structure wrt the object coming from a display
12754 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
12755 properties. (Bug#9284)
12757 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
12759 * fontset.c (fontset_get_font_group): Add proper type checks.

12789 2011-08-07 Juri Linkov <juri@jurta.org>
12791 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
12792 to show the arg `TIME' instead of `TIMEVAL'.
12794 2011-08-06 Eli Zaretskii <eliz@gnu.org>
12796 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
12797 display property strides EOL and includes a newline, as in
12798 longlines-mode. (Bug#9254)
12799 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
12800 word-wrap under bidirectional display. (Bug#9224)
12802 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
12803 is non-zero, even if the data buffer is NULL. Fixes a crash in
12804 vertical-motion with longlines-mode. (Bug#9254)
12806 2011-08-05 Eli Zaretskii <eliz@gnu.org>
12808 * bidi.c <bidi_cache_total_alloc>: Now static.

12811 * xdisp.c (display_line): Release buffer allocated for shelved bidi
12814 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
12815 amount allocated this far in `bidi_cache_total_alloc'.
12816 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
12817 non-zero, only free the data buffer without restoring the cache
12818 contents. All callers changed.
12820 * dispextern.h (bidi_unshelve_cache): Update prototype.
12822 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
12823 (move_it_in_display_line, move_it_to)
12824 (move_it_vertically_backward, move_it_by_lines): Replace the call
12825 to xfree to an equivalent call to bidi_unshelve_cache.
12826 (move_it_in_display_line_to): Fix logic of returning
12827 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
12829 2011-08-05 Eli Zaretskii <eliz@gnu.org>
12831 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that

12846 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
12848 * xterm.c (x_find_topmost_parent): New function.
12849 (x_set_frame_alpha): Find topmost parent window with
12850 x_find_topmost_parent and set the property there also (bug#9181).
12851 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
12853 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>

12879 for a display string or property. If found, set DISP_PROP_P
12882 * bidi.c (bidi_fetch_char): Accept an additional argument
12883 DISP_PROP_P, and pass it to compute_display_string_pos.
12884 Only handle text covered by a display string if DISP_PROP_P is returned
12885 non-zero. All callers of bidi_fetch_char changed.
12887 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>

12913 * regex.c (re_comp): Protoize.
12914 (re_exec): Fix return type.
12915 (regexec): Fix type of `ret'. (Bug#9203)
12917 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
12919 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
12920 This is needed if max-image-size is a floating-point number.
12922 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
12924 * print.c (print_object): Print empty symbol as ##.

12969 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
12971 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
12972 Without this fix, if a signal arrives just after memory fills up,
12973 'malloc' might be invoked reentrantly.
12975 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
12976 In other words, assume that every image size is allowed, on non-X
12977 hosts. This assumption is probably wrong, but it lets Emacs compile.

13000 (bidi_cache_find_level_change, bidi_cache_ensure_space)
13001 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
13002 (bidi_find_other_level_edge):
13003 Use ptrdiff_t instead of EMACS_INT where either will do.
13004 This works better on 32-bit hosts configured --with-wide-int.
13005 (bidi_cache_ensure_space): Check for size-calculation overflow.
13006 Use % rather than repeated addition, for better worst-case speed.
13007 Don't set bidi_cache_size until after xrealloc returns, because it
13009 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
13010 (bidi_cache_ensure_space): Also check that the bidi cache size
13011 does not exceed that of the largest Lisp string or buffer. See Eli
13012 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
13014 * alloc.c (__malloc_size_t): Remove.
13015 All uses replaced by size_t. See Andreas Schwab's note
13016 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
13018 * image.c: Improve checking for integer overflow.
13019 (check_image_size): Assume that f is nonnull, since
13020 it is always nonnull in practice. This is one less thing to
13021 worry about when checking for integer overflow later.
13022 (x_check_image_size): New function, which checks for integer
13023 overflow issues inside X.
13024 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
13025 This removes the need for a memory_full check.
13026 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
13027 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
13028 (xbm_read_bitmap_data): Change locals back to 'int', since
13029 their values must fit in 'int'.
13030 (xpm_load_image, png_load, tiff_load):
13031 Invoke x_create_x_image_and_pixmap earlier,
13032 to avoid much needless work if the image is too large.
13033 (tiff_load): Treat overly large images as if
13034 x_create_x_image_and_pixmap failed, not as malloc failures.
13035 (gs_load): Use x_check_image_size.
13037 * gtkutil.c: Omit integer casts.
13038 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
13039 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
13041 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
13043 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
13044 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
13045 would wrongly return t on a 64-bit host.
13047 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
13048 The plain *_OVERFLOW macros run afoul of GCC bug 49705
13049 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
13050 and therefore cause GCC to emit a bogus diagnostic in some cases.
13052 * image.c: Integer signedness and overflow and related fixes.
13053 This is not an exhaustive set of fixes, but it's time to
13054 record what I've got.
13055 (lookup_pixel_color, check_image_size): Remove redundant decls.
13056 (check_image_size): Don't assume that arbitrary EMACS_INT values
13057 fit in 'int', or that arbitrary 'double' values fit in 'int'.
13058 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
13059 (tiff_load, imagemagick_load_image):
13060 Check for overflow in size calculations.
13061 (x_create_x_image_and_pixmap): Remove unnecessary test for
13062 xmalloc returning NULL; that can't happen.
13063 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
13064 (xpm_color_bucket): Use better integer hashing function.
13065 (xpm_cache_color): Don't possibly over-allocate memory.
13066 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
13067 (gif_memory_source):
13068 Use ptrdiff_t, not int or size_t, to record sizes.
13069 (png_load): Don't assume values greater than 2**31 fit in 'int'.
13070 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
13071 either works, as we prefer signed integers.
13072 (tiff_read_from_memory, tiff_write_from_memory):
13073 Return tsize_t, not size_t, since that's what the TIFF API wants.
13074 (tiff_read_from_memory): Don't fail simply because the read would
13075 go past EOF; instead, return a short read.
13076 (tiff_load): Omit no-longer-needed casts.
13077 (Fimagemagick_types): Don't assume size fits into 'int'.
13079 Improve hashing quality when configured --with-wide-int.
13080 * fns.c (hash_string): New function, taken from sxhash_string.
13081 Do not discard information about ASCII character case; this
13082 discarding is no longer needed.
13083 (sxhash-string): Use it. Change sig to match it. Caller changed.
13084 * lisp.h: Declare it.
13085 * lread.c (hash_string): Remove, since we now use fns.c's version.
13086 The fns.c version returns a wider integer if --with-wide-int is
13087 specified, so this should help the quality of the hashing a bit.
13089 * emacs.c: Integer overflow minor fix.
13090 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
13091 Define only if GNU_LINUX.
13092 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
13094 * dispnew.c: Integer signedness and overflow fixes.
13095 Remove unnecessary forward decls, that were a maintenance hassle.
13096 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
13098 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
13099 (scrolling_window): Use ptrdiff_t, not int, for byte count.
13100 (prepare_desired_row, line_draw_cost):
13101 Use int, not unsigned, where either works.
13102 (save_current_matrix, restore_current_matrix):
13103 Use ptrdiff_t, not size_t, where either works.
13104 (init_display): Check for overflow more accurately, and without
13105 relying on undefined behavior.
13107 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
13108 Remove, replacing with the new symbols in lisp.h. All uses changed.
13109 * fileio.c (make_temp_name):
13110 * filelock.c (lock_file_1, lock_file):
13111 * xdisp.c (message_dolog):
13112 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
13113 Use pMd etc. instead.
13114 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
13115 replacing the pWIDE etc. symbols removed from editfns.c.
13117 * keyboard.h (num_input_events): Now uintmax_t.
13118 This is (very slightly) less likely to mess up due to wraparound.
13121 * buffer.c: Integer signedness fixes.
13122 (alloc_buffer_text, enlarge_buffer_text):
13123 Use ptrdiff_t rather than size_t when either will do, as we prefer
13126 * alloc.c: Integer signedness and overflow fixes.
13127 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
13128 (__malloc_size_t): Default to size_t, not to int.
13129 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
13130 (Fgarbage_collect, mark_object_loop_halt, mark_object):
13131 Prefer ptrdiff_t to size_t when either would do, as we prefer
13133 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
13134 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
13135 Now const. Initialize with values that are in range even if char
13137 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
13138 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
13139 These functions do the right thing with sizes > 2**32.
13140 (check_depth): Now ptrdiff_t, not int.
13141 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
13142 Adjust to new way of storing sizes. Check for size overflow bugs
13144 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
13145 slightly wrong anyway, as it missed one instance of
13146 XMALLOC_OVERRUN_CHECK_OVERHEAD.
13147 (refill_memory_reserve): Omit needless cast to size_t.
13148 (mark_object_loop_halt): Mark as externally visible.
13150 * xselect.c: Integer signedness and overflow fixes.
13151 (Fx_register_dnd_atom, x_handle_dnd_message):
13152 Use ptrdiff_t, not size_t, since we prefer signed.
13153 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
13154 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
13155 x_dnd_atoms_size and x_dnd_atoms_length.
13157 * doprnt.c: Prefer signed to unsigned when either works.
13159 * doprnt.c (doprnt):
13161 * xdisp.c (vmessage):
13162 Use ptrdiff_t, not size_t, when using or implementing doprnt,
13163 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
13164 prefer signed arithmetic to avoid comparison confusion.
13165 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
13166 but is a bit tricky.
13168 Assume freestanding C89 headers, string.h, stdlib.h.
13169 * data.c, doprnt.c, floatfns.c, print.c:
13170 Include float.h unconditionally.
13171 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
13172 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
13173 * regex.c: Likewise for stddef.h, string.h.
13174 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
13175 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
13176 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
13177 (STDC_HEADERS): Remove obsolete defines.
13178 * sysdep.c: Include limits.h unconditionally.
13180 Assume support for memcmp, memcpy, memmove, memset.
13181 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
13182 * regex.c (memcmp, memcpy):
13183 Remove; we assume C89 now.
13185 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
13186 (__malloc_safe_bcopy): Remove; no longer needed.
13188 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
13189 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
13190 well either way, and we prefer signed to unsigned.
13192 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
13194 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
13195 closes the connection while we're reading (bug#9182).
13197 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
13199 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
13200 are specified (Bug#9168).
13202 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
13204 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
13205 Found by GCC static checking and --with-wide-int on a 32-bit host.
13207 2011-07-25 Eli Zaretskii <eliz@gnu.org>
13209 * xdisp.c (compute_display_string_pos): Fix logic of caching
13210 previous display string position. Initialize cached_prev_pos to
13211 -1. Fixes slow-down at the beginning of a buffer.
13213 2011-07-24 Eli Zaretskii <eliz@gnu.org>
13215 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
13216 for attrs[LFACE_FONTSET_INDEX].
13218 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
13220 * xml.c (parse_region): Remove unused local
13221 that was recently introduced.
13223 2011-07-23 Eli Zaretskii <eliz@gnu.org>
13225 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
13226 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
13228 * xdisp.c (move_it_in_display_line_to): Record the best matching
13229 position for TO_CHARPOS while scanning the line, and restore it on
13230 exit if none of the characters scanned was an exact match.
13231 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
13232 when exact match is impossible due to invisible text, and the
13233 lines are truncated.
13235 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
13237 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
13240 2011-07-22 Eli Zaretskii <eliz@gnu.org>
13242 Fix a significant slow-down of cursor motion with C-n, C-p,
13243 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
13244 auto-repeat under bidi redisplay in fontified buffers.
13245 * xdisp.c (compute_stop_pos_backwards): New function.
13246 (next_element_from_buffer): Call compute_stop_pos_backwards to
13247 find a suitable prev_stop when we find ourselves before
13249 (reseat): Don't look for prev_stop, as that could mean a very long
13251 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
13252 <cached_disp_overlay_modiff>: Cache for last found display string
13254 (compute_display_string_pos): Return the cached position if asked
13255 about the same buffer in the same area of character positions, and
13256 the buffer wasn't changed since the time the display string
13257 position was cached.
13259 2011-07-22 Eli Zaretskii <eliz@gnu.org>
13261 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
13262 is an integer, which is important for empty lines. (Bug#9149)
13264 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
13266 * frame.c (Fmodify_frame_parameters): In tty case, update the
13267 default face if necessary (Bug#4238).
13269 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
13271 * editfns.c (Fstring_to_char): No need to explain what a character
13272 is in the docstring (Bug#6576).
13274 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
13276 * xml.c (parse_region): Make sure we always return a tree.
13278 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
13280 * xml.c (parse_region): If a document contains only comments,
13283 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
13285 * xml.c (make_dom): Return comments, too.
13287 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
13290 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
13291 and the surrounding thread.
13292 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
13293 rather than fgets, and retry after EINTR. Otherwise, 'emacs
13294 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
13296 * s/openbsd.h (BROKEN_SIGIO): Define.
13297 * unexelf.c (unexec) [__OpenBSD__]:
13298 Don't update the .mdebug section of the Alpha COFF symbol table.
13300 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
13302 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
13305 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
13307 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
13308 This fixes some race conditions on the permissions of any newly
13311 * alloc.c (valid_pointer_p): Use pipe, not open.
13312 This fixes some permissions issues when debugging.
13314 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
13315 If fchown fails to set both uid and gid, try to set just gid,
13316 as that is sometimes allowed. Adjust the file's mode to eliminate
13317 setuid or setgid bits that are inappropriate if fchown fails.
13319 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
13321 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
13322 to compare Lisp_Objects.
13323 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
13324 global_gnutls_log_level, don't mistake it for a Lisp_Object.
13325 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
13327 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
13329 * lread.c (read_integer): Unread even EOF character.
13330 (read1): Likewise. Properly record start position of symbol.
13332 * lread.c (read1): Read `#:' as empty uninterned symbol if no
13333 symbol character follows.
13335 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
13337 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
13338 This works around a problem with the previous change to Fcopy_file.
13339 Recent glibc declares fchown with __attribute__((warn_unused_result)),
13340 and without this change, GCC might complain about discarding
13341 fchown's return value.
13343 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
13345 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
13347 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
13349 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
13351 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
13353 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
13354 it's used from the C level.
13356 * process.c: Use the same condition for POLL_FOR_INPUT in both
13357 keyboard.c and process.c (bug#1858).
13359 2011-07-09 Lawrence Mitchell <wence@gmx.li>
13361 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
13362 (Fgnutls_boot): Use it.
13364 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
13366 * doc.c (Fsubstitute_command_keys): Revert last change.
13368 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
13370 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
13371 quotes the next character, and doesn't affect other longer
13372 sequences (bug#8935).
13374 * lread.c (syms_of_lread): Clarify that is isn't only
13375 `eval-buffer' and `eval-defun' that's affected by
13376 `lexical-binding' (bug#8460).
13378 2011-07-15 Eli Zaretskii <eliz@gnu.org>
13380 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
13381 bidi redisplay when a line includes both an image and is truncated.
13383 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
13385 Fix minor problems found by static checking.
13386 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
13387 (elsz): Now a signed constant, not a size_t var. We prefer signed
13388 types to unsigned, to avoid integer comparison confusion. Without
13389 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
13390 "cannot optimize loop, the loop counter may overflow", a symptom
13392 * indent.c (Fvertical_motion): Mark locals as initialized.
13393 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
13395 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
13397 * search.c (Fre_search_backward): Mention `case-fold-search' in
13398 all the re_search_* functions (bug#8138).
13400 * keyboard.c (Fopen_dribble_file): Document when the file is
13403 2011-07-14 Eli Zaretskii <eliz@gnu.org>
13405 * bidi.c (bidi_dump_cached_states): Fix format of displaying
13408 Support bidi reordering of display and overlay strings.
13409 * xdisp.c (compute_display_string_pos)
13410 (compute_display_string_end): Accept additional argument STRING.
13411 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
13412 (reseat_to_string): Initialize bidi_it->string.s and
13413 bidi_it->string.schars.
13414 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
13415 NULL (avoids a crash in bidi_paragraph_init).
13416 Initialize itb.string.lstring.
13417 (init_iterator): Call bidi_init_it only of a valid
13418 buffer position was specified. Initialize paragraph_embedding to
13420 (reseat_to_string): Initialize the bidi iterator.
13421 (display_string): If we need to ignore text properties of
13422 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
13423 original value of -1 will not work with bidi.)
13424 (compute_display_string_pos): First arg is now struct
13425 `text_pos *'; all callers changed. Support display properties on
13427 (compute_display_string_end): Support display properties on Lisp
13429 (init_iterator, reseat_1, reseat_to_string): Initialize the
13430 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
13431 when iterating on a string not from display properties).
13432 (compute_display_string_pos, compute_display_string_end):
13433 Fix calculation of the object to scan. Fixes an error when using
13435 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
13436 base_level_stop; instead, set base_level_stop to BEGV.
13437 Fixes crashes in vertical-motion.
13438 (next_element_from_buffer): Improve commentary for when
13439 the iterator is before prev_stop.
13440 (init_iterator): Initialize bidi_p from the default value of
13441 bidi-display-reordering, not from buffer-local value. Use the
13442 buffer-local value only if initializing for buffer iteration.
13443 (handle_invisible_prop): Support invisible properties on strings
13444 that are being bidi-reordered.
13445 (set_iterator_to_next): Support bidi reordering of C strings and
13447 (next_element_from_string): Support bidi reordering of Lisp
13449 (handle_stop_backwards): Support Lisp strings as well.
13450 (display_string): Support display of R2L glyph rows.
13451 Use IT_STRING_CHARPOS when displaying from a Lisp string.
13452 (init_iterator): Don't initialize it->bidi_p for strings
13454 (reseat_to_string): Initialize it->bidi_p for strings here.
13455 (next_element_from_string, next_element_from_c_string)
13456 (next_element_from_buffer): Add xassert's for correspondence

13915 * alloc.c (mark_buffer):
13916 * buffer.c (reset_buffer_local_variables, Fbuffer_local_variables)
13917 (clone_per_buffer_values): Don't assume that
13918 sizeof (struct buffer) is a multiple of sizeof (Lisp_Object).
13919 This isn't true in general, and it's particularly not true
13920 if Emacs is configured with --with-wide-int.
13921 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
13922 New macros, used in the buffer.c change.

13958 Random fixes. E.g., (random) never returned negative values.
13959 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
13960 subseconds part to the entropy, as that's a bit more random.
13961 Prefer signed to unsigned, since the signedness doesn't matter and
13962 in general we prefer signed. When given a limit, use a
13963 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
13964 latter isn't right if USE_2_TAGS_FOR_INTS.
13965 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
13966 not 0..VALMASK. Don't discard "excess" bits that random () returns.

13970 * textprop.c (text_property_stickiness):
13971 Obey Vtext_property_default_nonsticky.

13978 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
13979 This is more efficient than Ffile_directory_p and avoids a minor race.
13981 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
13983 * buffer.c (Foverlay_put): Say what the return value is
13986 * fileio.c (barf_or_query_if_file_exists): Check first if the file
13987 is a directory before asking whether to use the file name
13989 (barf_or_query_if_file_exists): Make the "File is a directory"
13990 error be more correct.
13992 * fns.c (Frequire): Remove the mention of the .gz files, since
13993 that's installation-specific, but keep the mention of
13994 `get-load-suffixes'.

14004 (syms_of_gnutls): Remove duplicate DEFSYM for
14005 Qgnutls_bootprop_verify_hostname_error, an error for
14006 Qgnutls_bootprop_verify_error (which is no longer used).
14008 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
14009 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
14010 Also (re)move comments that are misplaced or no longer relevant.
14012 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
14014 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

14073 (syms_of_keymap): Defsubr make-composed-keymap.
14074 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

14111 * eval.c (struct backtrace): Simplify and port the data structure.
14112 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
14113 signed bit field, as this assumption is not portable and it makes
14114 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
14115 "char debug_on_exit : 1" as this is not portable either; instead,
14116 use the portable "unsigned int debug_on_exit : 1". Remove unused
14117 member evalargs. Remove obsolete comments about cc bombing out.
14119 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

14335 The following patches are for when GLYPH_DEBUG && !XASSERT.
14336 * dispextern.h (trace_redisplay_p, dump_glyph_string):
14337 * dispnew.c (flush_stdout):
14338 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
14339 Mark as externally visible.
14340 * dispnew.c (check_window_matrix_pointers): Now static.
14341 * dispnew.c (window_to_frame_vpos):
14342 * xfns.c (unwind_create_frame):
14343 * xterm.c (x_check_font): Remove unused local.
14344 * scroll.c (CHECK_BOUNDS):
14345 * xfaces.c (cache_fache): Rename local to avoid shadowing.
14346 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
14347 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
14348 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
14349 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
14351 (debug_method_add): Use va_list and vsprintf rather than relying
14352 on undefined behavior with wrong number of arguments.
14353 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
14354 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
14355 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
14356 since we're not interested in debugging glyphs with old libraries.
14357 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
14358 GCC 4.6.0's static checking.
14360 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
14362 Integer overflow and signedness fixes (Bug#8873).

14371 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
14372 (x_create_bitmap_from_xpm_data):
14373 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
14374 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
14376 * xfaces.c (load_pixmap):
14377 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
14378 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
14379 (.bitmaps_last, struct x_output.icon_bitmap):
14380 Use ptrdiff_t, not int, for bitmap indexes.
14381 (x_allocate_bitmap_record): Check for size overflow.
14382 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
14384 Use ptrdiff_t, not int, for overlay counts.
14385 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
14386 * editfns.c (overlays_around, get_pos_property):
14387 * textprop.c (get_char_property_and_overlay):
14388 * xdisp.c (next_overlay_change, note_mouse_highlight):
14389 * xfaces.c (face_at_buffer_position):
14390 * buffer.c (OVERLAY_COUNT_MAX): New macro.
14391 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
14392 (Fnext_overlay_change, Fprevious_overlay_change)
14393 (mouse_face_overlay_overlaps, Foverlays_in):
14394 Use ptrdiff_t, not int, for sizes.
14395 (overlays_at, overlays_in): Check for size-calculation overflow.
14397 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
14399 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
14400 (x_session_initialize): Do not assume string length fits in int.
14402 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
14403 This is unlikely, but can occur if DPI is outlandish.
14405 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
14406 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
14408 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
14409 * xrdb.c (magic_file_p, search_magic_path):
14410 Omit last arg SUFFIX; it was always 0. All callers changed.
14411 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
14413 * xfont.c (xfont_match): Avoid need for strlen.
14415 * xfns.c: Don't assume strlen fits in int.
14416 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
14418 * xdisp.c (message_log_check_duplicate): Return intmax_t,
14419 not unsigned long, as we prefer signed integers. All callers changed.
14420 Detect integer overflow in repeat count.
14421 (message_dolog): Don't assume print length fits in 39 bytes.
14422 (display_mode_element): Don't assume strlen fits in int.
14424 * termcap.c: Don't assume sizes fit in int and never overflow.
14425 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
14426 (gobble_line): Check for size-calculation overflow.
14428 * minibuf.c (Fread_buffer):
14429 * lread.c (intern, intern_c_string):
14430 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
14431 Don't assume string length fits in int.
14433 * keyboard.c (parse_tool_bar_item):
14434 * gtkutil.c (style_changed_cb): Avoid need for strlen.
14436 * font.c: Don't assume string length fits in int.
14437 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
14438 Use ptrdiff_t, not int.
14439 (font_intern_prop): Don't assume string length fits in int.
14440 Don't assume integer property fits in fixnum.
14441 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
14443 * filelock.c: Fix some buffer overrun and integer overflow issues.
14444 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
14445 Reformulate so as not to need the command string.
14446 Invoke gzip -cd rather than gunzip, as it's more portable.
14447 (lock_info_type, lock_file_1, lock_file):
14448 Don't assume pid_t and time_t fit in unsigned long.
14449 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
14450 (current_lock_owner): Prefer signed type for sizes.
14451 Use memcpy, not strncpy, where memcpy is what is really wanted.
14452 Don't assume (via atoi) that time_t and pid_t fit in int.
14453 Check for time_t and/or pid_t out of range, e.g., via a network share.
14454 Don't alloca where an auto var works fine.
14456 * fileio.c: Fix some integer overflow issues.
14457 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
14458 Don't assume string length fits in int.
14459 (directory_file_name): Don't assume string length fits in long.
14460 (make_temp_name): Don't assume pid fits in int, or that its print
14461 length is less than 20.
14463 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
14465 * coding.c (make_subsidiaries): Don't assume string length fits in int.
14467 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
14469 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
14470 We prefer signed integers, even for size calculations.
14472 * emacs.c: Don't assume string length fits in 'int'.
14473 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
14474 (main): Don't invoke strlen when not needed.
14476 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
14477 (XD_DEBUG_MESSAGE): Don't waste a byte.
14479 * callproc.c (getenv_internal_1, getenv_internal)
14480 (Fgetenv_internal):
14481 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
14483 * lread.c (invalid_syntax): Omit length argument.
14484 All uses changed. This doesn't fix a bug, but it simplifies the
14485 code away from its former Hollerith-constant appearance, and it's
14486 one less 'int' to worry about when looking at integer-overflow issues.
14487 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
14489 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
14490 This didn't break anything, but it didn't help either.
14491 It's confusing to put a bogus integer in a place where the actual
14492 value does not matter.
14493 (LIST_END_P): Remove unused macro and its bogus comment.
14494 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
14496 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
14497 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
14499 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
14500 We prefer signed types, and the value cannot exceed the EMACS_INT
14501 range anyway (because otherwise the length would not be representable).
14502 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
14503 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
14504 This avoids a GCC warning when WIDE_EMACS_INT.
14506 * indent.c (sane_tab_width): New function.
14507 (current_column, scan_for_column, Findent_to, position_indentation)
14508 (compute_motion): Use it. This is just for clarity.
14509 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
14511 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
14513 * lisp.h (lint_assume): New macro.
14514 * composite.c (composition_gstring_put_cache):
14515 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
14517 * editfns.c, insdel.c:
14518 Omit unnecessary forward decls, to simplify future changes.
14520 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
14522 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
14524 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
14525 Use much-faster test for byte-length change.
14526 Don't assume string byte-length fits in 'int'.
14527 Check that character arg fits in 'int'.
14528 (mapcar1): Declare byte as byte, for clarity.
14530 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
14532 * fns.c (concat): Catch string overflow earlier.
14533 Do not rely on integer wraparound.
14535 * dispextern.h (struct it.overlay_strings_charpos)
14536 (struct it.selective): Now EMACS_INT, not int.
14537 * xdisp.c (forward_to_next_line_start)
14538 (back_to_previous_visible_line_start)
14539 (reseat_at_next_visible_line_start, next_element_from_buffer):
14540 Don't arbitrarily truncate the value of 'selective' to int.
14542 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
14544 * composite.c: Don't truncate sizes to 'int'.
14545 (composition_gstring_p, composition_reseat_it)
14546 (composition_adjust_point): Use EMACS_INT, not int.
14547 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
14548 not EMACS_UINT, for indexes.
14550 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
14552 * buffer.c: Include <verify.h>.
14553 (struct sortvec.priority, struct sortstr.priority):
14554 Now EMACS_INT, not int.
14555 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
14556 (struct sortstr.size, record_overlay_string)
14557 (struct sortstrlist.size, struct sortlist.used):
14558 Don't truncate size to int.
14559 (record_overlay_string): Check for size-calculation overflow.
14560 (init_buffer_once): Check at compile-time, not run-time.
14562 2011-06-22 Jim Meyering <meyering@redhat.com>
14564 Don't leak an XBM-image-sized buffer
14565 * image.c (xbm_load): Free the image buffer after using it.
14567 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
14570 * composite.c (find_automatic_composition): Omit needless 'return 0;'
14571 that Sun C diagnosed.
14572 * fns.c (secure_hash): Fix pointer signedness issue.
14573 * intervals.c (static_offset_intervals): New function.
14574 (offset_intervals): Use it.
14576 2011-06-21 Leo Liu <sdl.web@gmail.com>
14579 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
14582 * fns.c (secure_hash): Rename from crypto_hash_function and change
14583 the first arg to accept symbols.
14584 (Fsecure_hash): New primitive.
14585 (syms_of_fns): New symbols.
14587 2011-06-20 Deniz Dogan <deniz@dogan.se>
14589 * process.c (Fset_process_buffer): Clarify return value in
14592 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
14594 * dispnew.c (add_window_display_history): Use BVAR.
14596 * xdisp.c (debug_method_add): Use BVAR.
14597 (check_window_end, dump_glyph_matrix, dump_glyph)
14598 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
14600 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
14603 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
14604 check till after the cache is created in init_frame_faces.
14606 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
14608 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
14610 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
14612 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
14613 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
14614 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
14616 Improve buffer-overflow checking (Bug#8873).
14617 * fileio.c (Finsert_file_contents):
14618 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
14619 Remove the old (too-loose) buffer overflow checks.
14620 They weren't needed, since make_gap checks for buffer overflow.
14621 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
14622 The old code merely checked for Emacs fixnum overflow, and relied
14623 on undefined (wraparound) behavior. The new code avoids undefined
14624 behavior, and also checks for ptrdiff_t and/or size_t overflow.
14626 * editfns.c (Finsert_char): Don't dump core with very negative counts.
14627 Tune. Don't use wider integers than needed. Don't use alloca.
14628 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
14630 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
14632 * insdel.c, lisp.h (buffer_overflow): New function.
14633 (insert_from_buffer_1, replace_range, replace_range_2):
14634 * insdel.c (make_gap_larger):
14635 * editfns.c (Finsert_char):
14636 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
14638 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
14640 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
14642 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
14644 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
14645 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
14647 * fileio.c: Don't assume EMACS_INT fits in off_t.
14648 (emacs_lseek): New static function.
14649 (Finsert_file_contents, Fwrite_region): Use it.
14650 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
14652 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
14654 * fns.c: Don't overflow int when computing a list length.
14655 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
14656 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
14657 truncation on 64-bit hosts. Check for QUIT every
14658 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
14659 faster and is responsive enough.
14660 (Flength): Report an error instead of overflowing an integer.
14661 (Fsafe_length): Return a float if the value is not representable
14662 as a fixnum. This shouldn't happen except in contrived situations.
14663 (Fnthcdr, Fsort): Don't assume list length fits in int.
14664 (Fcopy_sequence): Don't assume vector length fits in int.
14666 * alloc.c: Check that resized vectors' lengths fit in fixnums.
14667 (header_size, word_size): New constants.
14668 (allocate_vectorlike): Don't check size overflow here.
14669 (allocate_vector): Check it here instead, since this is the only
14670 caller of allocate_vectorlike that could cause overflow.
14671 Check that the new vector's length is representable as a fixnum.
14673 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
14674 The previous code was bogus. For example, next_almost_prime (32)
14675 returned 39, which is undesirable as it is a multiple of 3; and
14676 next_almost_prime (24) returned 25, which is a multiple of 5 so
14677 why was the code bothering to check for multiples of 7?
14679 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
14681 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
14683 Variadic C functions now count arguments with ptrdiff_t.
14684 This partly undoes my 2011-03-30 change, which replaced int with size_t.
14685 Back then I didn't know that the Emacs coding style prefers signed int.
14686 Also, in the meantime I found a few more instances where arguments
14687 were being counted with int, which may truncate counts on 64-bit
14688 machines, or EMACS_INT, which may be unnecessarily wide.
14689 * lisp.h (struct Lisp_Subr.function.aMANY)
14690 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
14691 Arg counts are now ptrdiff_t, not size_t.
14692 All variadic functions and their callers changed accordingly.
14693 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
14694 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
14695 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
14696 * callint.c (Fcall_interactively): Check arg count for overflow,
14697 to avoid potential buffer overrun. Use signed char, not 'int',
14698 for 'varies' array, so that we needn't bother to check its size
14699 calculation for overflow.
14700 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
14701 * eval.c (apply_lambda):
14702 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
14703 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
14704 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
14706 * callint.c (Fcall_interactively): Don't use index var as event count.
14708 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
14709 * mem-limits.h (SIZE): Remove; no longer used.
14711 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
14713 Remove unnecessary casts.
14714 * xterm.c (x_term_init):
14715 * xfns.c (x_set_border_pixel):
14716 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
14717 These aren't needed now that we assume ANSI C.
14719 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
14720 It's more likely to cause problems (due to unsigned overflow)
14723 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
14725 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
14727 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
14729 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
14731 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
14733 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
14735 GLYPH_CODE_FACE returns EMACS_INT, not int.
14736 * dispextern.h (merge_faces):
14737 * xfaces.c (merge_faces):
14738 * xdisp.c (get_next_display_element, next_element_from_display_vector):
14739 Don't assume EMACS_INT fits in int.
14741 * character.h (CHAR_VALID_P): Remove unused parameter.
14742 * fontset.c, lisp.h, xdisp.c: All uses changed.
14744 * editfns.c (Ftranslate_region_internal): Omit redundant test.
14746 * fns.c (concat): Minor tuning based on overflow analysis.
14747 This doesn't fix any bugs. Use int to hold character, instead
14748 of constantly refetching from Emacs object. Use XFASTINT, not
14749 XINT, for value known to be a character. Don't bother comparing
14750 a single byte to 0400, as it's always less.
14752 * floatfns.c (Fexpt):
14753 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
14755 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
14758 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
14760 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
14761 Without this fix, on a 64-bit host (aset S 0 4294967386) would
14762 incorrectly succeed when S was a string, because 4294967386 was
14763 truncated before it was used.
14765 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
14766 Otherwise, an out-of-range integer could cause undefined behavior
14769 * composite.c: Use int, not EMACS_INT, for characters.
14770 (fill_gstring_body, composition_compute_stop_pos): Use int, not
14771 EMACS_INT, for values that are known to be in character range.
14772 This doesn't fix any bugs but is the usual style inside Emacs and
14773 may generate better code on 32-bit machines.
14775 Make sure a 64-bit char is never passed to ENCODE_CHAR.
14776 This is for reasons similar to the recent CHAR_STRING fix.
14777 * charset.c (Fencode_char): Check that character arg is actually
14778 a character. Pass an int to ENCODE_CHAR.
14779 * charset.h (ENCODE_CHAR): Verify that the character argument is no
14780 wider than 'int', as a compile-time check to prevent future regressions
14783 * character.c (char_string): Remove unnecessary casts.
14785 Make sure a 64-bit char is never passed to CHAR_STRING.
14786 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
14787 by silently ignoring the top 32 bits, allowing some values
14788 that were far too large to be valid characters.
14789 * character.h: Include <verify.h>.
14790 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
14791 arguments are no wider than unsigned, as a compile-time check
14792 to prevent future regressions in this area.
14794 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
14795 (Fsubst_char_in_region):
14797 * xdisp.c (decode_mode_spec_coding):
14798 Adjust to CHAR_STRING's new requirement.
14799 * editfns.c (Finsert_char, Fsubst_char_in_region):
14800 * fns.c (concat): Check that character args are actually
14801 characters. Without this test, these functions did the wrong
14802 thing with wildly out-of-range values on 64-bit hosts.
14804 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
14805 These casts should not be needed on 32-bit hosts, either.
14806 * keyboard.c (read_char):
14807 * lread.c (Fload): Remove casts to unsigned.
14809 * lisp.h (UNSIGNED_CMP): New macro.
14810 This fixes comparison bugs on 64-bit hosts.
14811 (ASCII_CHAR_P): Use it.
14812 * casefiddle.c (casify_object):
14813 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
14814 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
14815 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
14816 * dispextern.h (FACE_FROM_ID):
14817 * keyboard.c (read_char): Use UNSIGNED_CMP.
14819 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
14820 not to EMACS_INT, to avoid GCC warning.
14822 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
14824 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
14825 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
14826 isn't needed on 32-bit machines.
14828 * buffer.c (Fgenerate_new_buffer_name):
14829 Use EMACS_INT for count, not int.
14830 (advance_to_char_boundary): Return EMACS_INT, not int.
14832 * data.c (Qcompiled_function): Now static.
14834 * window.c (window_body_lines): Now static.
14836 * image.c (gif_load): Rename local to avoid shadowing.
14838 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
14839 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
14840 * alloc.c (make_save_value): Integer argument is now of type
14841 ptrdiff_t, not int.
14842 (mark_object): Use ptrdiff_t, not int.
14843 * lisp.h (pD): New macro.
14844 * print.c (print_object): Use it.
14846 * alloc.c: Use EMACS_INT, not int, to count objects.
14847 (total_conses, total_markers, total_symbols, total_vector_size)
14848 (total_free_conses, total_free_markers, total_free_symbols)
14849 (total_free_floats, total_floats, total_free_intervals)
14850 (total_intervals, total_strings, total_free_strings):
14851 Now EMACS_INT, not int. All uses changed.
14852 (Fgarbage_collect): Compute overall total using a double, so that
14853 integer overflow is less likely to be a problem. Check for overflow
14854 when converting back to an integer.
14855 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
14856 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
14857 These were 'int' variables that could overflow on 64-bit hosts;
14858 they were never used, so remove them instead of repairing them.
14859 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
14860 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
14861 Previously, this ceilinged at INT_MAX, but that doesn't work on
14863 (allocate_pseudovector): Don't use EMACS_INT when int would do.
14865 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
14866 (allocate_vectorlike): Check for ptrdiff_t overflow.
14867 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
14868 when a (possibly-narrower) signed value would do just as well.
14869 We prefer using signed arithmetic, to avoid comparison confusion.
14871 * alloc.c: Catch some string size overflows that we were missing.
14872 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
14873 for convenience in STRING_BYTES_MAX.
14874 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
14875 The definition here is exact; the one in lisp.h was approximate.
14876 (allocate_string_data): Check for string overflow. This catches
14877 some instances we weren't catching before. Also, it catches
14878 size_t overflow on (unusual) hosts where SIZE_MAX <= min
14879 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
14880 and ptrdiff_t and EMACS_INT are both 64 bits.
14882 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
14883 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
14884 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
14886 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
14888 * alloc.c (Fmake_string): Check for out-of-range init.
14890 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
14892 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
14894 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
14896 * xfns.c (x_set_scroll_bar_default_width): Remove argument to

14900 (int_gtk_range_get_value): Move to the scroll bar part of the file.
14901 (style_changed_cb): Call update_theme_scrollbar_width and call
14902 x_set_scroll_bar_default_width and xg_frame_set_char_size for
14903 all frames (Bug#8505).
14904 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
14905 Call gtk_window_set_resizable if HAVE_GTK3.
14906 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
14907 and height if HAVE_GTK3 (Bug#8505).
14908 (scroll_bar_width_for_theme): New variable.
14909 (update_theme_scrollbar_width): New function.
14910 (xg_get_default_scrollbar_width): Move code to
14911 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.

14914 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
14916 * emacsgtkfixed.c, emacsgtkfixed.h: New files.

14923 * window.c (temp_output_buffer_show): Call display_buffer with
14924 second argument Vtemp_buffer_show_specifiers and reset latter
14925 immediately after the call.
14926 (Vtemp_buffer_show_specifiers): New variable.
14927 (auto_window_vscroll_p, next_screen_context_lines)
14928 (Vscroll_preserve_screen_position): Remove leading asterisks from

15472 next/previous character if nothing is cached there yet, or if we
15473 were just reseat()'ed to a new position.
15475 * xdisp.c (set_cursor_from_row): Set start and stop points
15476 according to the row's direction when priming the loop that looks
15477 for the glyph on which to display cursor.

15479 (display_prop_intangible_p): Reimplement to call
15480 handle_display_spec instead of single_display_spec_intangible_p.

15491 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
15492 value of a `display' property is a "replacing spec".
15493 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
15494 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
15495 the display property, but just return a value indicating whether
15496 the display property will replace the characters it covers.
15497 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
15498 frame_window_p members of struct bidi_it.

15524 * gnutls.c: Use Emacs's memory allocators.
15525 Without this change, the gnutls library would invoke malloc etc.
15526 directly, which causes problems on non-SYNC_INPUT hosts, and which
15527 runs afoul of improving memory_full behavior. (Bug#8761)
15528 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
15529 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
15530 xfree instead of the default malloc, realloc, free.
15531 (Fgnutls_boot): No need to check for memory allocation failure,
15532 since xmalloc does that for us.

15557 Check for overflow in vector size calculations.
15558 * ccl.c (ccl_driver):
15559 Check for overflow when converting EMACS_INT to int.

15561 need to be updated by these changes.
15562 * fns.c (make_hash_table, maybe_resize_hash_table):
15563 Check for integer overflow with large hash tables.
15564 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
15565 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
15566 (SXHASH_REDUCE): New macro.
15567 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
15568 Use it instead of discarding useful hash info with large hash values.
15569 (sxhash_float): New function.
15570 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
15571 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
15572 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
15573 Rewrite to use FIXNUM_BITS, as this simplifies things.
15574 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
15575 Adjust signatures to match updated version of code.
15576 (consing_since_gc): Now EMACS_INT, since a single hash table can
15577 use more than INT_MAX bytes.

15626 Make it possible to run ./temacs.
15628 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
15629 syms_of_callproc does the same thing. Remove test for
15630 "initialized", do it in the caller.
15631 * emacs.c (main): Avoid calling set_initial_environment when dumping.
15633 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
15635 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
15636 (read_minibuf): Use get_minibuffer.
15637 (syms_of_minibuf): Use DEFSYM.
15638 (Qmetadata): New var.
15639 * data.c (Qbuffer): Don't make it static.
15640 (syms_of_data): Use DEFSYM.
15642 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
15644 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
15645 (CCL_CODE_MIN): New macro.
15647 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
15649 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
15651 * eval.c (Qdebug): Now static.
15652 * lisp.h (Qdebug): Remove decl. This reverts a part of the
15653 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
15654 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
15656 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
15658 * image.c: Various fixes to ImageMagick code comments.
15659 (Fimagemagick_types): Doc fix.
15661 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
15663 Minor fixes prompted by GCC 4.6.0 warnings.
15665 * xselect.c (converted_selections, conversion_fail_tag): Now static.
15667 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
15668 (x_clipboard_manager_save_all): Move extern decl to ...
15669 * xterm.h: ... here, so that it can be checked for consistency.
15671 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
15673 * xselect.c (x_clipboard_manager_save_frame)
15674 (x_clipboard_manager_save_all): New functions.
15675 (Fx_clipboard_manager_save): Lisp function deleted.
15677 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
15678 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
15680 * xterm.h: Update prototype.
15682 2011-05-28 William Xu <william.xwl@gmail.com>
15684 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
15685 exiting (Bug#8239).
15687 2011-05-28 Jim Meyering <meyering@redhat.com>
15689 Avoid a sign-extension bug in crypto_hash_function.
15690 * fns.c (to_uchar): Define.
15691 (crypto_hash_function): Use it to convert some newly-signed
15692 variables to unsigned, to avoid sign-extension bugs. For example,
15693 without this change, (md5 "truc") would evaluate to
15694 45723a2aff78ff4fff7fff1114760e62 rather than the expected
15695 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
15696 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
15698 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
15700 Integer overflow fixes.
15702 * dbusbind.c: Serial number integer overflow fixes.
15703 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
15704 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
15705 to hold a serial number that is too large for a fixnum.
15706 (Fdbus_method_return_internal, Fdbus_method_error_internal):
15707 Check for serial numbers out of range. Decode any serial number
15708 that was so large that it became a float. (Bug#8722)
15710 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
15711 (Fdbus_call_method, Fdbus_call_method_asynchronously):
15712 Use XFASTINT rather than XUINT when numbers are nonnegative.
15713 (xd_append_arg, Fdbus_method_return_internal):
15714 (Fdbus_method_error_internal): Likewise. Also, for unsigned
15715 arguments, check that Lisp number is nonnegative, rather than
15716 silently wrapping negative numbers around. (Bug#8722)
15717 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
15720 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
15722 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
15724 ccl: Add integer overflow checks.
15725 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
15726 (IN_INT_RANGE): New macros.
15727 (ccl_driver): Use them to check for integer overflow when
15728 decoding a CCL program. Many of the new checks are whether XINT (x)
15729 fits in int; it doesn't always, on 64-bit hosts. The new version
15730 doesn't catch all possible integer overflows, but it's an
15731 improvement. (Bug#8719)
15733 * alloc.c (make_event_array): Use XINT, not XUINT.
15734 There's no need for unsigned here.
15736 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
15737 This follows up to the 2011-05-06 change that substituted uintptr_t
15738 for EMACS_INT. This case wasn't caught back then.
15740 Rework Fformat to avoid integer overflow issues.
15741 * editfns.c: Include <float.h> unconditionally, as it's everywhere
15742 now (part of C89). Include <verify.h>.
15743 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
15744 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
15745 (Fformat): Avoid the prepass trying to compute sizes; it was only
15746 approximate and thus did not catch overflow reliably. Instead, walk
15747 through the format just once, formatting and computing sizes as we go,
15748 checking for integer overflow at every step, and allocating a larger
15749 buffer as needed. Keep track separately whether the format is
15750 multibyte. Keep only the most-recently calculated precision, rather
15751 than them all. Record whether each argument has been converted to
15752 string. Use EMACS_INT, not int, for byte and char and arg counts.
15753 Support field widths and precisions larger than INT_MAX. Avoid
15754 sprintf's undefined behavior with conversion specifications such as %#d
15755 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
15756 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
15757 formatting out-of-range floating point numbers with int
15758 formats. (Bug#8668)
15760 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
15762 * data.c: Avoid integer truncation in expressions involving floats.
15763 * data.c: Include <intprops.h>.
15764 (arith_driver): When there's an integer overflow in an expression
15765 involving floating point, convert the integers to floating point
15766 so that the resulting value does not suffer from catastrophic
15767 integer truncation. For example, on a 64-bit host (* 4
15768 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
15769 Do not rely on undefined behavior after integer overflow.
15771 merge count_size_as_multibyte, parse_str_to_multibyte
15772 * character.c, character.h (count_size_as_multibyte):
15773 Rename from parse_str_to_multibyte; all uses changed.
15774 Check for integer overflow.
15775 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
15776 since it's now a duplicate of the other. This is more of
15777 a character than a buffer op, so better that it's in character.c.
15778 * fns.c, print.c: Adjust to above changes.
15780 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
15782 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
15784 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
15786 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
15787 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
15788 (x_clipboard_manager_save): Now static.
15789 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
15791 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
15792 (crypto_hash_function): Now static.
15793 Fix pointer signedness problems. Avoid unnecessary initializations.
15795 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
15797 * termhooks.h (Vselection_alist): Make it terminal-local.
15799 * terminal.c (create_terminal): Initialize it.
15801 * xselect.c: Support for clipboard managers.
15802 (Vselection_alist): Move to termhooks.h as terminal-local var.
15803 (LOCAL_SELECTION): New macro.
15804 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
15805 (symbol_to_x_atom): Remove gratuitous arg.
15806 (x_handle_selection_request, lisp_data_to_selection_data)
15807 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
15808 (x_own_selection, x_get_local_selection, x_convert_selection):
15809 New arg, specifying work frame. Use terminal-local Vselection_alist.
15810 (some_frame_on_display): Delete unused function.
15811 (Fx_own_selection_internal, Fx_get_selection_internal)
15812 (Fx_disown_selection_internal, Fx_selection_owner_p)
15813 (Fx_selection_exists_p): New optional frame arg.
15814 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
15815 (x_handle_selection_clear): Don't treat other terminals with the
15816 same keyboard specially. Use the terminal-local Vselection_alist.
15817 (x_clear_frame_selections): Use Frun_hook_with_args.
15819 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
15821 * xterm.h: Add support for those atoms.
15823 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
15825 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
15826 (converted_selections, conversion_fail_tag): New global variables.
15827 (x_selection_request_lisp_error): Free the above.
15828 (x_get_local_selection): Remove unnecessary code.
15829 (x_reply_selection_request): Args changed; handle arbitrary array
15830 of converted selections stored in converted_selections.
15831 Separate the XChangeProperty and SelectionNotify steps.
15832 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
15833 (x_convert_selection): New function.
15834 (x_handle_selection_event): Simplify.
15835 (x_get_foreign_selection): Don't ignore incoming requests while
15836 waiting for an answer; this will fail when we implement
15837 SAVE_TARGETS, and seems unnecessary anyway.
15838 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
15839 (Vx_sent_selection_functions): Doc fix.
15841 2011-05-26 Leo Liu <sdl.web@gmail.com>
15843 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
15845 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15847 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
15849 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
15850 for fringe update if it has periodic bitmap.
15851 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
15852 and fringe_bitmap_periodic_p.
15854 * fringe.c (get_fringe_bitmap_data): New function.
15855 (draw_fringe_bitmap_1, update_window_fringes): Use it.
15856 (update_window_fringes): Record periodicity of fringe bitmap in glyph
15857 row. Mark glyph row for fringe update if periodicity changed.
15859 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
15860 for fringe update unless it has periodic bitmap.
15862 2011-05-25 Kenichi Handa <handa@m17n.org>
15864 * xdisp.c (get_next_display_element): Set correct it->face_id for
15865 a static composition.
15867 2011-05-24 Leo Liu <sdl.web@gmail.com>
15870 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
15872 * fns.c (crypto_hash_function, Fsha1): New function.
15873 (Fmd5): Use crypto_hash_function.
15874 (syms_of_fns): Add Ssha1.
15876 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
15878 * gnutls.c: Remove unused macros.
15879 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
15880 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
15881 Remove macros that are defined and never used.
15882 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
15884 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
15886 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
15887 (Fx_get_selection_internal): Minor cleanup.
15888 (Fx_own_selection_internal): Rename arguments for consistency with
15891 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
15893 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
15895 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
15897 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
15899 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15901 * dispnew.c (scrolling_window): Don't exclude the case that the
15902 last enabled row in the desired matrix touches the bottom boundary.
15904 2011-05-21 Glenn Morris <rgm@gnu.org>
15906 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
15907 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
15908 and add some more files.
15910 2011-05-20 Eli Zaretskii <eliz@gnu.org>
15912 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
15913 report_file_error introduced by the change from 2011-05-07.
15915 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
15917 * systime.h (Time): Define only if emacs is defined.
15918 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
15919 where the include path doesn't have X11/X.h by default. See
15920 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
15922 2011-05-20 Kenichi Handa <handa@m17n.org>
15924 * composite.c (find_automatic_composition): Fix previous change.
15926 2011-05-20 Glenn Morris <rgm@gnu.org>
15928 * lisp.mk: New file, split from Makefile.in.
15929 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
15930 (shortlisp): Remove.
15931 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
15933 2011-05-19 Glenn Morris <rgm@gnu.org>
15935 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
15936 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
15937 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
15938 (lisp): Set the order to that of loadup.el.
15939 (shortlisp): Make it a copy of $lisp.
15940 (SOME_MACHINE_LISP): Remove.
15941 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
15942 Use just $shortlisp, not $SOME_MACHINE_LISP too.
15944 2011-05-18 Kenichi Handa <handa@m17n.org>
15946 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
15947 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
15948 (find_automatic_composition): Mostly rewrite for efficiency.
15950 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
15952 * makefile.w32-in: Update dependencies.
15954 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
15956 * menu.c: Include limits.h (fixes the MS-Windows build broken by
15957 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
15959 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
15961 Fix some integer overflow issues, such as string length overflow.
15963 * insdel.c (count_size_as_multibyte): Check for string overflow.
15965 * character.c (lisp_string_width): Check for string overflow.
15966 Use EMACS_INT, not int, for string indexes and lengths; in
15967 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
15968 the resulting string length overflows an EMACS_INT; instead,
15969 report a string overflow if no precision given. When checking for
15970 precision exhaustion, use a check that cannot possibly have
15971 integer overflow. (Bug#8675)
15972 * character.h (lisp_string_width): Adjust to new signature.
15974 * alloc.c (string_overflow): New function.
15975 (Fmake_string): Use it. This doesn't change behavior, but saves
15976 a few bytes and will simplify future changes.
15977 * character.c (string_escape_byte8): Likewise.
15978 * lisp.h (string_overflow): New decl.
15980 Fixups, following up to the user-interface timestamp change.
15981 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
15982 for UI timestamps, instead of unsigned long.
15983 * msdos.c (mouse_get_pos): Likewise.
15984 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
15985 * w32gui.h (Time): Define by including "systime.h" rather than by
15986 declaring it ourselves. (Bug#8664)
15988 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
15989 * image.c (clear_image_cache): Likewise.
15991 * term.c (term_mouse_position): Don't assume time_t wraparound.
15993 Be more systematic about user-interface timestamps.
15994 Before, the code sometimes used 'Time', sometimes 'unsigned long',
15995 and sometimes 'EMACS_UINT', to represent these timestamps.
15996 This change causes it to use 'Time' uniformly, as that's what X uses.
15997 This makes the code easier to follow, and makes it easier to catch
15998 integer overflow bugs such as Bug#8664.
15999 * frame.c (Fmouse_position, Fmouse_pixel_position):
16000 Use Time, not unsigned long, for user-interface timestamps.
16001 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
16002 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
16003 * keyboard.h (last_event_timestamp): Likewise.
16004 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
16005 * menu.h (xmenu_show): Likewise.
16006 * term.c (term_mouse_position): Likewise.
16007 * termhooks.h (struct input_event.timestamp): Likewise.
16008 (struct terminal.mouse_position_hook): Likewise.
16009 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
16010 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
16011 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
16012 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
16013 what it was before.
16014 * menu.h, termhooks.h: Include "systime.h", for Time.
16016 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
16017 Don't assume that the difference between two unsigned long values
16018 can fit into an integer. At this point, we know button_down_time
16019 <= event->timestamp, so the difference must be nonnegative, so
16020 there's no need to cast the result if double-click-time is
16021 nonnegative, as it should be; check that it's nonnegative, just in
16022 case. This bug is triggered when events are more than 2**31 ms
16023 apart (about 25 days). (Bug#8664)
16025 * xselect.c (last_event_timestamp): Remove duplicate decl.
16026 (x_own_selection): Remove needless cast to unsigned long.
16028 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
16029 that always fit in int. Use a sentinel instead of a counter, to
16030 avoid a temp and to allay GCC's concerns about possible int overflow.
16031 * frame.h (struct frame): Use int for menu_bar_items_used
16032 instead of EMACS_INT, since it always fits in int.
16034 * menu.c (grow_menu_items): Check for int overflow.
16036 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
16038 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
16039 Before, the code was not consistent. These values cannot exceed
16040 2**31 - 1 so there's no need to make them unsigned.
16041 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
16042 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
16043 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
16045 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
16047 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
16048 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
16049 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
16050 presumably because the widths might not match.
16052 * window.c (size_window): Avoid needless test at loop start.
16054 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
16056 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
16058 2011-05-12 Drew Adams <drew.adams@oracle.com>
16060 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
16062 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16064 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
16065 `width' to `bar_area_x' and `bar_area_width', respectively.
16066 (x_scroll_run): Take account of fringe background extension.
16068 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
16069 Rename local vars `left' and `width' to `bar_area_x' and
16070 `bar_area_width', respectively.
16071 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
16072 background extension.
16074 2011-05-10 Jim Meyering <meyering@redhat.com>
16076 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
16078 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
16080 * image.c (Finit_image_library): Return t for built-in image types,
16081 like pbm and xbm. (Bug#8640)
16083 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
16085 * w32menu.c (set_frame_menubar): Fix submenu allocation.
16087 2011-05-07 Eli Zaretskii <eliz@gnu.org>
16089 * w32console.c (Fset_screen_color): Doc fix.
16090 (Fget_screen_color): New function.
16091 (syms_of_ntterm): Defsubr it.
16093 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
16094 unlink the temporary file if Fcall_process didn't create it in the
16096 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
16097 child process will be redirected to a file specified with `:file'.
16098 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
16099 cue to call_process_cleanup not to close that handle.
16101 2011-05-07 Ben Key <bkey76@gmail.com>
16103 * makefile.w32-in: The bootstrap-temacs rule now makes use of
16104 one of two shell specific rules, either bootstrap-temacs-CMD or
16105 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
16106 to the previous implementation of the bootstrap-temacs rule.
16107 The bootstrap-temacs-CMD rule is similar to the previous
16108 implementation of the bootstrap-temacs rule except that it
16109 makes use of the ESC_CFLAGS variable instead of the CFLAGS
16112 These changes, along with some changes to nt/configure.bat,
16113 nt/gmake.defs, and nt/nmake.defs, are required to extend my
16114 earlier fix to add support for --cflags and --ldflags options
16115 that include quotes so that it works whether make uses cmd or
16118 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
16120 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
16121 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
16123 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
16124 a string. Handle both cases.
16125 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
16126 (Fdbus_register_method): Use Qinvalid_function.
16128 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
16130 * makefile.w32-in: Update dependencies.
16131 (LISP_H): Add inttypes.h and stdin.h.
16132 (PROCESS_H): Add unistd.h.
16134 2011-05-06 Eli Zaretskii <eliz@gnu.org>
16136 * lread.c: Include limits.h (fixes the MS-Windows build broken by
16137 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
16139 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
16141 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
16143 * term.c (vfatal): Remove stray call to va_end.
16144 It's not needed and the C Standard doesn't allow it here anyway.
16146 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
16147 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
16149 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
16152 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
16154 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
16156 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
16158 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
16160 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
16162 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
16163 * charset.c (Fdefine_charset_internal): Don't initialize
16164 charset.code_space[15]. The value was garbage, on hosts with
16165 32-bit int (Bug#8600).
16167 * lread.c (read_integer): Be more consistent with string-to-number.
16168 Use string_to_number to do the actual conversion; this avoids
16169 rounding errors and fixes some other screwups. Without this fix,
16170 for example, #x1fffffffffffffff was misread as -2305843009213693952.
16171 (digit_to_number): Move earlier, for benefit of read_integer.
16172 Return -1 if the digit is out of range for the base, -2 if it is
16173 not a digit in any supported base. (Bug#8602)
16175 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
16177 * dispnew.c (scrolling_window): Return 1 if we scrolled,
16178 to match comment at start of function. This also removes a
16179 GCC warning about overflow in a 32+64-bit port.
16181 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
16183 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
16184 Reported by Stefan Monnier in
16185 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
16186 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
16187 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
16189 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
16190 (EMACS_UINTPTR): Likewise, with uintptr_t.
16192 * lisp.h: Prefer 64-bit EMACS_INT if available.
16193 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
16194 on 32-bit hosts that have 64-bit int, so that they can access
16196 However, temporarily disable this change unless the temporary
16197 symbol WIDE_EMACS_INT is defined.
16199 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
16201 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
16202 This removes an assumption that EMACS_INT and long are the same
16203 width as pointers. The assumption is true for Emacs porting targets
16204 now, but we want to make other targets possible.
16205 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
16206 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
16207 In the rest of the code, change types of integers that hold casted
16208 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
16209 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
16210 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
16211 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
16212 No need to cast type when ORing.
16213 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
16214 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
16215 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
16216 assume EMACS_INT is the same width as char *.
16217 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
16218 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
16219 Remove no-longer-needed casts.
16220 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
16221 (xg_tool_bar_help_callback, xg_make_tool_item):
16222 Use EMACS_INTPTR to hold an integer
16223 that will be cast to void *; this can avoid a GCC warning
16224 if EMACS_INT is not the same width as void *.
16225 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
16226 * xdisp.c (display_echo_area_1, resize_mini_window_1):
16227 (current_message_1, set_message_1):
16228 Use a local to convert to proper width without a cast.
16229 * xmenu.c (dialog_selection_callback): Likewise.
16231 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
16232 Also, don't assume VALBITS / RAND_BITS is less than 5,
16233 and don't rely on undefined behavior when shifting a 1 left into
16235 * lisp.h (get_random): Change signature to match.
16237 * lread.c (hash_string): Use size_t, not int, for hash computation.
16238 Normally we prefer signed values; but hashing is special, because
16239 it's better to use unsigned division on hash table sizes so that
16240 the remainder is nonnegative. Also, size_t is the natural width
16241 for hashing into memory. The previous code used 'int', which doesn't
16242 retain enough info to hash well into very large tables.
16243 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
16245 * dbusbind.c: Don't possibly lose pointer info when converting.
16246 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
16247 Use XPNTR rather than XHASH, so that the high-order bits of
16248 the pointer aren't lost when converting through void *.
16250 * eval.c (Fautoload): Don't double-shift a pointer.
16252 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
16254 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
16256 * gnutls.c (DEF_GNUTLS_FN):
16257 * image.c (DEF_IMGLIB_FN): Make function pointers static.
16259 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
16261 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
16264 2011-05-05 Eli Zaretskii <eliz@gnu.org>
16266 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
16267 New version that can reserve upto 2GB of heap space.
16269 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
16271 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
16273 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
16275 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
16276 `gnutls_certificate_set_x509_key_file'.
16278 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
16280 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
16281 Update dependencies.
16283 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
16285 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
16286 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
16287 Remove unused parameter `fildes'.
16288 * process.c (read_process_output, send_process): Don't pass it.
16290 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
16292 Fix previous change: the library cache is defined in w32.c.
16293 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
16294 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
16296 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
16298 Implement dynamic loading of GnuTLS on Windows.
16300 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
16301 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
16302 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
16305 * gnutls.c (Qgnutls_dll): Define.
16306 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
16307 (gnutls_*): Declare function pointers.
16308 (init_gnutls_functions): New function to initialize function pointers.

16311 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
16312 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
16313 (emacs_gnutls_write, emacs_gnutls_read)
16314 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
16315 (Fgnutls_available_p): New function.
16316 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
16317 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
16318 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
16320 * image.c: Include w32.h.
16321 (Vimage_type_cache): Delete.
16322 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
16323 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
16324 (w32_delayed_load): Move to w32.c.
16326 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
16328 * w32.c (QCloaded_from, Vlibrary_cache): Define.
16329 (w32_delayed_load): Move from image.c. When loading a library, record
16330 its filename in the :loaded-from property of the library id.
16331 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
16332 Initialize and staticpro them.
16333 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
16335 * process.c: Include lisp.h before w32.h, not after.
16336 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
16337 instead of gnutls_record_check_pending.
16339 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
16341 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
16343 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
16344 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
16347 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
16349 * xterm.c (x_set_frame_alpha): Do not set property on anything
16350 else than FRAME_X_OUTER_WINDOW (Bug#8608).
16352 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
16354 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)

16372 * sysdep.c (wait_for_termination_1): Make static.
16373 (wait_for_termination, interruptible_wait_for_termination):
16374 Move after wait_for_termination_1.
16376 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
16378 * sysdep.c (interruptible_wait_for_termination): New function
16379 which is like wait_for_termination, but allows keyboard
16382 * callproc.c (Fcall_process): Add (:file "file") as an option for
16384 (Fcall_process_region): Ditto.
16386 2011-04-30 Eli Zaretskii <eliz@gnu.org>
16388 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
16389 rather than `XVECTOR (FOO)->size'.
16391 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
16392 inttypes.h, as a gnulib replacement is used if it not available in
16395 2011-04-21 Eli Zaretskii <eliz@gnu.org>
16397 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
16398 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
16399 of MOST_POSITIVE_FIXNUM. (Bug#8528)
16401 * coding.c (coding_alloc_by_realloc): Error out if destination
16402 will grow beyond MOST_POSITIVE_FIXNUM.
16403 (decode_coding_emacs_mule): Abort if there isn't enough place in

16413 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
16414 %llo or %llx format is passed. (Bug#8545)
16416 * window.c (window_scroll_line_based): Use a marker instead of
16417 simple variables to record original value of point. (Bug#7952)
16419 * doprnt.c (doprnt): Fix the case where a multibyte sequence
16420 produced by %s or %c overflows available buffer space. (Bug#8545)
16422 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
16424 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
16425 (SIZE_MAX): Move defn after all includes, as they might #define it.
16427 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
16429 * w32.c (init_environment): Warn about defaulting HOME to C:\.

16437 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
16439 2011-04-28 Eli Zaretskii <eliz@gnu.org>
16441 * doprnt.c (doprnt): Don't return value smaller than the buffer
16442 size if the message was truncated. (Bug#8545).

16449 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
16451 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
16453 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
16455 * makefile.w32-in: Update dependencies.
16457 2011-04-27 Eli Zaretskii <eliz@gnu.org>
16459 Improve `doprnt' and its usage. (Bug#8545)
16460 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
16461 `format_end'. Remove support for %l as a conversion specifier.
16462 Don't use xrealloc. Improve diagnostics when the %l size modifier
16463 is used. Update the commentary.
16465 * eval.c (verror): Simplify calculation of size_t.
16467 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
16470 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
16472 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
16475 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
16477 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
16478 This makes this file independent of the recent pseudovector change.
16480 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
16482 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
16484 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
16485 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
16486 Remove unused local.
16487 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
16489 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
16490 GCC 4.6.0 optimizes based on type-based alias analysis.
16491 For example, if b is of type struct buffer * and v of type struct
16492 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
16493 != &v->size, and therefore "v->size = 1; b->size = 2; return
16494 v->size;" must therefore return 1. This assumption is incorrect
16495 for Emacs, since it type-puns struct Lisp_Vector * with many other
16496 types. To fix this problem, this patch adds a new type struct
16497 vectorlike_header that documents the constraints on layout of vectors
16498 and pseudovectors, and helps optimizing compilers not get fooled
16499 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
16500 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
16501 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
16503 (XSETPVECTYPE): Rewrite in terms of new macro.
16504 (XSETPVECTYPESIZE): New macro, specifying both type and size.
16505 This is a bit clearer, and further avoids the possibility of
16506 undesirable aliasing.
16507 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
16508 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
16509 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
16510 since Lisp_Subr is a special case (no "next" field).
16511 (ASIZE): Now uses header.size rather than size.
16512 All previous uses of XVECTOR (foo)->size replaced to use this macro,
16513 to avoid the hassle of writing XVECTOR (foo)->header.size.
16514 (struct vectorlike_header): New type.
16515 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
16516 object, to help avoid aliasing.
16517 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
16518 (SUBRP): Likewise, since Lisp_Subr is a special case.
16519 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
16520 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
16521 (struct Lisp_Hash_Table): Combine first two members into a single
16522 struct vectorlike_header member. All uses of "size" and "next" members
16523 changed to be "header.size" and "header.next".
16524 * buffer.h (struct buffer): Likewise.
16525 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
16526 * frame.h (struct frame): Likewise.
16527 * process.h (struct Lisp_Process): Likewise.
16528 * termhooks.h (struct terminal): Likewise.
16529 * window.c (struct save_window_data, struct saved_window): Likewise.
16530 * window.h (struct window): Likewise.
16531 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
16532 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
16533 * buffer.c (init_buffer_once): Likewise.
16534 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
16536 * process.c (Fformat_network_address): Use local var for size,
16539 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
16541 Make the Lisp reader and string-to-float more consistent (Bug#8525)
16542 * data.c (atof): Remove decl; no longer used or needed.
16543 (digit_to_number): Move to lread.c.
16544 (Fstring_to_number): Use new string_to_number function, to be
16545 consistent with how the Lisp reader treats infinities and NaNs.
16546 Do not assume that floating-point numbers represent EMACS_INT
16547 without losing information; this is not true on most 64-bit hosts.
16548 Avoid double-rounding errors, by insisting on integers when
16549 parsing non-base-10 numbers, as the documentation specifies.
16550 * lisp.h (string_to_number): New decl, replacing ...
16551 (isfloat_string): Remove.
16552 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
16553 (read1): Do not accept +. and -. as integers; this
16554 appears to have been a coding error. Similarly, do not accept
16555 strings like +-1e0 as floating point numbers. Do not report
16556 overflow for integer overflows unless the base is not 10 which
16557 means we have no simple and reliable way to continue.
16558 Break out the floating-point parsing into a new
16559 function string_to_number, so that Fstring_to_number parses
16560 floating point numbers consistently with the Lisp reader.
16561 (digit_to_number): Move here from data.c. Make it static inline.
16562 (E_CHAR, EXP_INT): Remove, replacing with ...
16563 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
16564 (string_to_number): New function, replacing isfloat_string.
16565 This function checks for valid syntax and produces the resulting
16566 Lisp float number too. Rework it so that string-to-number
16567 no longer mishandles examples like "1.0e+". Use strtoumax,
16568 so that overflow for non-base-10 numbers is reported only when
16569 there's no portable and simple way to convert to floating point.
16571 * textprop.c (set_text_properties_1): Rewrite for clarity,
16572 and to avoid GCC warning about integer overflow.
16574 * intervals.h (struct interval): Use EMACS_INT for members
16575 where EMACS_UINT might cause problems. See
16576 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
16577 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
16578 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
16580 (offset_intervals): Tell GCC not to worry about length overflow
16581 when negating a negative length.
16583 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
16584 (overrun_check_free): Likewise.
16586 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
16587 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
16590 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
16591 (gnutls_make_error): Rename local to avoid shadowing.
16592 (gnutls_emacs_global_deinit): ifdef out; not used.
16593 (Fgnutls_boot): Use const for pointer to readonly storage.
16594 Comment out unused local. Fix pointer signedness problems.
16596 * lread.c (openp): Don't stuff size_t into an 'int'.
16597 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
16598 about possible signed overflow.
16600 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
16601 (GDK_KEY_g): Don't define if already defined.
16602 (xg_prepare_tooltip): Avoid pointer signedness problem.
16603 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
16605 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
16606 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
16608 * xfns.c (Fx_window_property): Simplify a bit,
16609 to make a bit faster and to avoid GCC 4.6.0 warning.
16610 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
16612 * fns.c (internal_equal): Don't assume size_t fits in int.
16614 * alloc.c (compact_small_strings): Tighten assertion a little.
16616 Replace pEd with more-general pI, and fix some printf arg casts.
16617 * lisp.h (pI): New macro, generalizing old pEd macro to other
16618 conversion specifiers. For example, use "...%"pI"d..." rather
16619 than "...%"pEd"...".
16620 (pEd): Remove. All uses replaced with similar uses of pI.
16621 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
16622 * alloc.c (check_pure_size): Don't overflow by converting size to int.
16623 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
16624 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
16625 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
16626 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
16627 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
16629 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
16630 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
16631 * print.c (safe_debug_print, print_object): Likewise.
16632 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
16634 Use pI instead of if-then-else-abort. Use %p to avoid casts,
16635 avoiding the 0 flag, which is not portable.
16636 * process.c (Fmake_network_process): Use pI to avoid cast.
16637 * region-cache.c (pp_cache): Likewise.
16638 * xdisp.c (decode_mode_spec): Likewise.
16639 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
16640 behavior on 64-bit hosts with printf arg.
16641 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
16642 (x_stop_queuing_selection_requests): Likewise.
16643 (x_get_window_property): Don't truncate byte count to an 'int'
16646 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
16647 here, since it parses constructs like leading '-' and spaces,
16648 which are not wanted; and it overflows with large numbers.
16649 Instead, simply match F[0-9]+, which is what is wanted anyway.
16651 * alloc.c: Remove unportable assumptions about struct layout.
16652 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
16653 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
16654 (allocate_vectorlike, make_pure_vector): Use the new macros,
16655 plus offsetof, to remove unportable assumptions about struct layout.
16656 These assumptions hold on all porting targets that I know of, but
16657 they are not guaranteed, they're easy to remove, and removing them
16658 makes further changes easier.
16660 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
16661 This doesn't fix a bug but makes the code clearer.
16662 (string_overrun_cookie): Now const. Use initializers that
16663 don't formally overflow signed char, to avoid warnings.
16664 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
16665 can cause Emacs to crash when string overrun checking is enabled.
16666 (allocate_buffer): Don't assume sizeof (struct buffer) is a
16667 multiple of sizeof (EMACS_INT); it need not be, if
16668 alignof(EMACS_INT) < sizeof (EMACS_INT).
16669 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
16671 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

16678 supposed to be handshaking. (Bug#8556)
16679 Reported by Paul Eggert <eggert@cs.ucla.edu>.
16681 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>

16698 2011-04-25 Eli Zaretskii <eliz@gnu.org>
16700 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
16701 "cast to pointer from integer of different size".
16703 Improve doprnt and its use in verror. (Bug#8545)
16704 * doprnt.c (doprnt): Document the set of format control sequences
16705 supported by the function. Use SAFE_ALLOCA instead of always
16708 * eval.c (verror): Don't limit the buffer size at size_max-1, that
16709 is one byte too soon. Don't use xrealloc; instead xfree and
16712 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
16714 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
16717 * gnutls.c: Renamed global_initialized to
16718 gnutls_global_initialized. Added internals for the
16719 :verify-hostname-error, :verify-error, and :verify-flags
16720 parameters of `gnutls-boot' and documented those parameters in the
16721 docstring. Start callback support.
16722 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
16723 unless a fatal error occurred. Call gnutls_alert_send_appropriate

16796 * doprnt.c: Include limits.h.
16797 (SIZE_MAX): New macro.
16798 (doprnt): Return a size_t value. 2nd arg is now size_t.
16799 Many local variables are now size_t instead of int or unsigned.
16800 Improve overflow protection. Support `l' modifier for integer
16801 conversions. Support %l conversion. Don't assume an EMACS_INT
16802 argument for integer conversions and for %c.
16804 * lisp.h (doprnt): Restore prototype.
16806 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
16807 $(SRC)/character.h.
16809 * Makefile.in (base_obj): Add back doprnt.o.
16811 * deps.mk (doprnt.o): Add back prerequisites.
16812 (callint.o): Depend on character.h.
16814 * eval.c (internal_lisp_condition_case): Include the handler
16815 representation in the error message.

16821 * callint.c (Fcall_interactively): When displaying error message
16822 about invalid control letter, pass the character's codepoint, not
16823 a pointer to its multibyte form. Improve display of the character
16824 in octal and display also its hex code.
16826 * character.c (char_string): Use %x to display the (unsigned)
16827 codepoint of an invalid character, to avoid displaying a bogus
16830 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
16831 `error', not SYMBOL_NAME itself.
16833 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
16834 character arguments to `error'.
16836 * charset.c (check_iso_charset_parameter): Fix incorrect argument
16837 to `error' in error message about FINAL_CHAR argument. Make sure
16838 FINAL_CHAR is a character, and use %c when it is passed as
16839 argument to `error'.

16903 Define only if needed.
16905 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
16906 by pacifying GCC about it. Maybe it's time to retire it?

16909 * dispextern.h (struct redisplay_interface): Rename param
16910 to avoid shadowing.
16911 * termhooks.h (struct terminal): Likewise.
16912 * xterm.c (xembed_send_message): Likewise.
16914 * insdel.c (make_gap_smaller): Define only if
16915 USE_MMAP_FOR_BUFFERS || REL_ALLOC || DOUG_LEA_MALLOC.
16917 * keyboard.c (read_char): Make a var volatile so longjmp won't clobber
16920 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,
16921 so that we aren't warned about unused symbols.
16923 * xfns.c (Fx_file_dialog): Rename local to avoid shadowing.
16925 * xdisp.c (x_produce_glyphs): Mark var as initialized (Bug#8512).
16927 * xfns.c (x_real_positions): Mark locals as initialized.

16932 (toolkit_scroll_bar_interaction): Define and use only if USE_X_TOOLKIT.
16933 (x_dispatch_event): Declare static if USE_GTK, and
16934 define if USE_GTK || USE_X_TOOLKIT.
16935 (SET_SAVED_BUTTON_EVENT): Define only if USE_X_TOOLKIT || USE_GTK.
16936 * xterm.h (x_dispatch_event): Extern only if USE_X_TOOLKIT.
16937 * xterm.c, xterm.h (x_mouse_leave): Bring this function back, but only
16938 if defined HAVE_MENUS && !defined USE_X_TOOLKIT && !defined USE_GTK.
16940 * xmenu.c (menu_help_callback): Pointer type fixes.
16941 Use const pointers when pointing at readonly data. Avoid pointer
16942 signedness clashes.

16944 (update_frame_menubar): Remove unused decl.
16946 * xfns.c (Fx_hide_tip): Move locals to avoid shadowing.

17389 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
17390 * dispextern.h (bidi_dump_cached_states): Remove, since it's
17391 exported only to the debugger.
17393 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
17394 * atimer.h (run_all_atimers): Remove; not exported.
17396 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
17397 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
17398 was inaccessible from Lisp.
17399 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
17400 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
17402 alloc.c: Import and export fewer symbols, and remove unused items.
17403 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
17405 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
17406 it's not optimized away by whole-program optimization.
17407 (message_enable_multibyte, free_misc): Remove.
17408 (catchlist, handlerlist, mark_backtrace):
17409 Declare only if BYTE_MARK_STACK.
17410 (mark_byte_stack): Likewise, fixing a ifdef-vs-if typo.
17411 * alloc.c (pure): Export only if VIRT_ADDR_VARIES is defined.
17412 (message_enable_multibyte): Remove decl.
17413 (free_misc, interval_free_list, float_block, float_block_index):
17414 (n_float_blocks, float_free_list, cons_block, cons_block_index):
17415 (cons_free_list, last_marked_index):
17417 (suppress_checking, die): Define only if ENABLE_CHECKING is defined.
17418 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
17419 (mark_backtrace): Define only if BYTE_MARK_STACK.
17420 * xdisp.c (message_enable_multibyte): Now static.
17422 Declare Lisp_Object Q* variables to be 'static' if not exported.
17423 This makes it easier for human readers (and static analyzers)
17424 to see whether these variables are used from other modules.
17425 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
17426 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
17427 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:
17428 * font.c, frame.c, fringe.c, ftfont.c, image.c, keyboard.c, keymap.c:
17429 * lread.c, macros.c, minibuf.c, print.c, process.c, search.c:
17430 * sound.c, syntax.c, textprop.c, window.c, xdisp.c, xfaces.c, xfns.c:
17431 * xmenu.c, xselect.c:
17432 Declare Q* vars static if they are not used in other modules.
17433 * ccl.h, character.h, charset.h, coding.h, composite.h, font.h:
17434 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
17435 Remove decls of unexported vars.
17436 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
17438 * lisp.h (DEFINE_FUNC): Make sname 'static'.
17440 Make Emacs functions such as Fatom 'static' by default.
17441 This makes it easier for human readers (and static analyzers)
17442 to see whether these functions can be called from other modules.
17443 DEFUN now defines a static function. To make the function external
17444 so that it can be used in other C modules, use the new macro DEFUE.
17445 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
17446 (Finit_image_library):
17447 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
17448 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
17449 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
17450 Remove decls, since these functions are now static.
17451 (Funintern, Fget_internal_run_time): New decls, since these functions
17452 were already external.
17454 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
17455 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:
17456 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, floatfns.c:
17457 * fns.c, font.c, fontset.c, frame.c, image.c, indent.c:
17458 * keyboard.c, keymap.c, lread.c:
17459 * macros.c, marker.c, menu.c, minibuf.c, print.c, process.c, search.c:
17460 * syntax.c, term.c, terminal.c, textprop.c, undo.c:
17461 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
17462 Mark functions with DEFUE instead of DEFUN,
17463 if they are used in other modules.
17464 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
17465 decls for now-static functions.
17466 * buffer.h (Fdelete_overlay): Remove decl.
17467 * callproc.c (Fgetenv_internal): Mark as internal.
17468 * composite.c (Fremove_list_of_text_properties): Remove decl.

17471 * dired.c (Ffile_attributes): New forward static decl.
17472 * doc.c (Fdocumntation_property): New forward static decl.
17473 * eval.c (Ffetch_bytecode): New forward static decl.
17474 (Funintern): Remove extern decl; now in .h file where it belongs.
17475 * fileio.c (Fmake_symbolic_link): New forward static decl.
17476 * image.c (Finit_image_library): New forward static decl.
17477 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
17478 * intervals.h (Fprevious_property_change):
17479 (Fremove_list_of_text_properties): Remove decls.
17480 * keyboard.c (Fthis_command_keys): Remove decl.
17481 (Fcommand_execute): New forward static decl.
17482 * keymap.c (Flookup_key): New forward static decl.
17483 (Fcopy_keymap): Now static.
17484 * keymap.h (Flookup_key): Remove decl.
17485 * process.c (Fget_process): New forward static decl.
17486 (Fprocess_datagram_address): Mark as internal.
17487 * syntax.c (Fsyntax_table_p): New forward static decl.
17488 (skip_chars): Remove duplicate decl.
17489 * textprop.c (Fprevious_property_change): New forward static decl.
17490 * window.c (Fset_window_fringes, Fset_window_scroll_bars):
17492 (Fset_window_margins, Fset_window_vscroll): New forward static decls.
17493 * window.h (Fset_window_vscroll, Fset_window_margins): Remove decls.

17497 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
17499 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
17502 2011-04-13 Eli Zaretskii <eliz@gnu.org>
17504 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
17505 when at ZV. (Bug#8487)
17507 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
17509 * charset.c (Fclear_charset_maps): Use xfree instead of free.
17511 * keyboard.c (parse_tool_bar_item): Likewise.
17512 * sound.c (sound_cleanup, alsa_close): Likewise.
17513 * termcap.c (tgetent): Likewise.
17514 * xfns.c (x_default_font_parameter): Likewise.
17515 * xsettings.c (read_and_apply_settings): Likewise.
17517 * alloc.c (overrun_check_malloc, overrun_check_realloc)
17518 (overrun_check_free): Protoize.
17520 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
17522 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
17523 since callers should never pass a negative size.
17524 Change the signature to match that of plain 'read' and 'write'; see
17525 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
17526 * lisp.h: Update prototypes of emacs_write and emacs_read.
17528 2011-04-11 Eli Zaretskii <eliz@gnu.org>
17530 * xdisp.c (redisplay_window): Don't try to determine the character
17531 position of the scroll margin if the window start point w->startp
17532 is outside the buffer's accessible region. (Bug#8468)
17534 2011-04-10 Eli Zaretskii <eliz@gnu.org>
17536 Fix write-region and its subroutines for buffers > 2GB.
17537 * fileio.c (a_write, e_write): Modify declaration of arguments and
17538 local variables to support buffers larger than 2GB.
17539 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
17541 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
17542 argument, local variables, and return value.
17544 * lisp.h: Update prototypes of emacs_write and emacs_read.
17546 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
17548 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
17550 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
17552 Fix more problems found by GCC 4.6.0's static checks.
17554 * xdisp.c (vmessage): Use a better test for character truncation.
17556 * charset.c (load_charset_map): <, not <=, for optimization,
17557 and to avoid potential problems with integer overflow.
17558 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
17559 * casetab.c (set_identity, shuffle): Likewise.
17560 * editfns.c (Fformat): Likewise.
17561 * syntax.c (skip_chars): Likewise.
17563 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
17564 This also lets GCC 4.6.0 generate slightly better loop code.
17566 * callint.c (Fcall_interactively): <, not <=, for optimization.
17567 (Fcall_interactively): Count the number of arguments produced,
17568 not the number of arguments given. This is simpler and lets GCC
17569 4.6.0 generate slightly better code.
17571 * ftfont.c: Distingish more carefully between FcChar8 and char.
17572 The previous code passed unsigned char * to a functions like
17573 strlen and xstrcasecmp that expect char *, which does not
17574 conform to the C standard.
17575 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
17576 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
17577 char * when the C standard requires it.
17579 * keyboard.c (read_char): Remove unused var.
17581 * eval.c: Port to Windows vsnprintf (Bug#8435).
17582 Include <limits.h>.
17583 (SIZE_MAX): Define if the headers do not.
17584 (verror): Do not give up if vsnprintf returns a negative count.
17585 Instead, grow the buffer. This ports to Windows vsnprintf, which
17586 does not conform to C99. Problem reported by Eli Zaretskii.
17587 Also, simplify the allocation scheme, by avoiding the need for
17588 calling realloc, and removing the ALLOCATED variable.
17590 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
17592 Remove invocations of doprnt, as Emacs now uses vsnprintf.
17593 But keep the doprint source code for now, as we might revamp it
17594 and use it again (Bug#8435).
17595 * lisp.h (doprnt): Remove.
17596 * Makefile.in (base_obj): Remove doprnt.o.
17597 * deps.mk (doprnt.o): Remove.
17599 error: Print 32- and 64-bit integers portably (Bug#8435).
17600 Without this change, on typical 64-bit hosts error ("...%d...", N)
17601 was used to print both 32- and 64-bit integers N, which relied on
17602 undefined behavior.
17603 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
17604 * lisp.h (error, verror): Mark as printf-like functions.
17605 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
17606 Report overflow in size calculations when allocating printf buffer.
17607 Do not truncate output string at its first null byte.
17608 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
17609 Truncate the output at a character boundary, since vsnprintf does not
17611 * charset.c (check_iso_charset_parameter): Convert internal
17612 character to string before calling 'error', since %c now has the
17614 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
17615 overflow when computing char to be passed to 'error'. Do not
17616 pass Lisp_Object to 'error'; pass the integer instead.
17617 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
17618 formatted with plain %d.
17620 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
17622 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
17624 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
17626 * xterm.c (x_catch_errors): Remove duplicate declaration.
17628 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
17630 * xdisp.c, lisp.h (message_nolog): Remove; unused.
17632 2011-04-10 Jim Meyering <meyering@redhat.com>
17634 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
17635 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
17636 return ssize_t not "int", and use size_t as the buffer length.
17637 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
17638 * gnutls.h: Update declarations.
17639 * process.c (read_process_output): Use ssize_t, to match.
17640 (send_process): Likewise.
17642 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
17644 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
17646 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
17648 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
17649 Use unsigned char, to match FcChar8 type definition.
17651 * xterm.c (handle_one_xevent):
17652 * xmenu.c (create_and_show_popup_menu):
17653 * xselect.c (x_decline_selection_request)
17654 (x_reply_selection_request): Avoid type-punned deref of X events.
17656 2011-04-09 Eli Zaretskii <eliz@gnu.org>
17658 Fix some uses of `int' instead of EMACS_INT.
17659 * search.c (string_match_1, fast_string_match)
17660 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
17661 (scan_buffer, find_next_newline_no_quit)
17662 (find_before_next_newline, search_command, Freplace_match)
17663 (Fmatch_data): Make some `int' variables be EMACS_INT.
17665 * xdisp.c (display_count_lines): 3rd argument and return value now
17666 EMACS_INT. All callers changed.
17667 (pint2hrstr): Last argument is now EMACS_INT.
17669 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
17670 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
17671 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
17672 (decode_coding_utf_16, decode_coding_emacs_mule)
17673 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
17674 (decode_coding_ccl, decode_coding_charset)
17675 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
17676 (decode_coding_iso_2022, decode_coding_emacs_mule)
17677 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
17678 <char_offset, last_offset>: Declare EMACS_INT.
17679 (encode_coding_utf_8, encode_coding_utf_16)
17680 (encode_coding_emacs_mule, encode_invocation_designation)
17681 (encode_designation_at_bol, encode_coding_iso_2022)
17682 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
17683 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
17685 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
17686 (encode_invocation_designation): Last argument P_NCHARS is now
17688 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
17689 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
17691 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
17694 * ccl.c (Fccl_execute_on_string): Declare some variables
17697 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
17699 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
17701 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
17703 * process.c (Fformat_network_address): Doc fix.
17705 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
17707 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
17709 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
17711 * keyboard.c (read_char): Call Lisp function help-form-show,
17712 instead of using internal_with_output_to_temp_buffer.
17713 (Qhelp_form_show): New var.
17714 (syms_of_keyboard): Use DEFSYM macro.
17716 * print.c (internal_with_output_to_temp_buffer): Function deleted.
17718 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
17720 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
17722 * process.c (Flist_processes): Remove to Lisp.
17723 (list_processes_1): Delete.
17725 2011-04-06 Eli Zaretskii <eliz@gnu.org>
17727 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
17729 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
17731 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
17733 Fix more problems found by GCC 4.6.0's static checks.
17735 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
17737 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
17739 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
17741 * xdisp.c (vmessage): Mark as a printf-like function.
17743 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
17745 * sound.c (sound_warning): Don't crash if arg contains a printf format.
17747 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
17748 printf-like functions.
17749 (tiff_load): Add casts to remove these marks before passing them
17750 to system-supplied API.
17752 * eval.c (Fsignal): Remove excess argument to 'fatal'.
17754 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
17755 This avoids several warnings with gcc -Wstrict-overflow.
17756 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
17757 directly, rather than having caller test rule sign. This avoids
17758 some unnecessary tests.
17759 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
17760 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
17761 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
17763 * xfont.c (xfont_text_extents): Remove var that was set but not used.
17764 (xfont_open): Avoid unnecessary tests.
17766 * composite.c (composition_gstring_put_cache): Use unsigned integer.
17768 * composite.h, composite.c (composition_gstring_put_cache):
17769 Use EMACS_INT, not int, for length.
17771 * composite.h (COMPOSITION_DECODE_REFS): New macro,
17772 breaking out part of COMPOSITION_DECODE_RULE.
17773 (COMPOSITION_DECODE_RULE): Use it.
17774 * composite.c (get_composition_id): Remove unused local vars,
17775 by using the new macro.
17777 * textprop.c (set_text_properties_1): Change while to do-while,
17778 since the condition is always true at first.
17780 * intervals.c (graft_intervals_into_buffer): Mark var as used.
17781 (interval_deletion_adjustment): Return unsigned value.
17784 * process.c (list_processes_1, create_pty, read_process_output):
17785 (exec_sentinel): Remove vars that were set but not used.
17786 (create_pty): Remove unnecessary "volatile"s.
17787 (Fnetwork_interface_info): Avoid possibility of int overflow.
17788 (read_process_output): Do adaptive read buffering even if carryover.
17789 (read_process_output): Simplify nbytes computation if buffered.
17791 * bytecode.c (exec_byte_code): Rename local to avoid shadowing.
17793 * syntax.c (scan_words): Remove var that was set but not used.
17794 (update_syntax_table): Use unsigned instead of int.
17796 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
17797 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
17798 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
17800 * print.c (print_error_message): Avoid int overflow.
17802 * font.c (font_list_entities): Redo for clarity,
17803 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
17805 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
17806 (font_score): Avoid potential overflow in diff calculation.
17808 * fns.c (substring_both): Remove var that is set but not used.
17809 (sxhash): Redo loop for clarity and to avoid wraparound warning.
17811 * eval.c (funcall_lambda): Rename local to avoid shadowing.
17813 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
17814 Otherwise, GCC 4.6.0 optimizes the loop check away since the check

17833 Check for integer overflow on size calculations.
17835 * buffer.c (Fprevious_overlay_change): Remove var that is set
17838 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
17839 Remove vars that are set but not used.

17848 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
17849 that are set but not used.
17851 * xfns.c (make_invisible_cursor): Don't return garbage
17852 if XCreateBitmapFromData fails (Bug#8410).
17854 * xselect.c (x_get_local_selection, x_handle_property_notify):
17855 Remove vars that are set but not used.
17857 * xfns.c (x_create_tip_frame): Remove var that is set but not used.

17861 Remove var that is set but not used.
17862 (scroll_bar_windows_size): Now size_t, not int.
17863 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
17864 Check for overflow.
17866 * xfaces.c (realize_named_face): Remove vars that are set but not used.
17867 (map_tty_color) [!defined MSDOS]: Likewise.
17869 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.

17881 * print.c (print_object): Remove var that is set but not used.
17883 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
17884 The gnulib version avoids calling malloc in the usual case,
17885 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
17886 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
17887 * filelock.c (current_lock_owner): Likewise.
17888 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
17889 * sysdep.c: Include allocator.h, careadlinkat.h.
17890 (emacs_no_realloc_allocator): New static constant.
17891 (emacs_readlink): New function.
17892 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
17893 ../lib/careadlinkat.h.
17895 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
17897 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the

17919 do not dereference NULL upon failed strdup
17920 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
17921 (ns_get_family): Likewise.
17923 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
17925 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
17927 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
17929 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
17932 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>

17945 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
17947 (syms_of_lread): Declare `lexical-binding'.
17949 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
17951 * keyboard.c (eval_dyn): New fun.
17952 (menu_item_eval_property): Use it.
17954 * image.c (parse_image_spec): Use Ffunctionp.
17956 * fns.c (concat, mapcar1): Accept byte-code-functions.
17958 * eval.c (Fsetq): Handle lexical vars.
17959 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
17960 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
17961 (FletX, Flet): Obey lexical binding.
17962 (Fcommandp): Handle closures.
17963 (Feval): New `lexical' arg.
17964 (eval_sub): New function extracted from Feval. Use it almost
17965 everywhere where Feval was used. Look up vars in lexical env.
17967 (Ffunctionp): Move from subr.el.
17968 (Ffuncall): Handle closures.
17969 (apply_lambda): Remove `eval_flags'.
17970 (funcall_lambda): Handle closures and new byte-code-functions.
17971 (Fspecial_variable_p): New function.
17972 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
17973 but without exporting it to Lisp.
17975 * doc.c (Fdocumentation, store_function_docstring):
17976 * data.c (Finteractive_form): Handle closures.
17978 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
17981 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
17983 (exec_byte_code): New function extracted from Fbyte_code to handle new
17984 calling convention for byte-code-functions. Add new byte-codes.
17986 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
17988 * alloc.c (Fmake_symbol): Init new `declared_special' field.

17992 * xdisp.c (redisplay_internal): Fix prototype.
17994 2011-03-31 Eli Zaretskii <eliz@gnu.org>
17996 * xdisp.c (SCROLL_LIMIT): New macro.
17997 (try_scrolling): Use it when setting scroll_limit.
17998 Limit scrolling to 100 screen lines.
17999 (redisplay_window): Even when falling back on "recentering",
18000 position point in the window according to scroll-conservatively,
18001 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
18003 (try_scrolling): When point is above the window, allow searching
18004 as far as scroll_max, or one screenful, to compute vertical
18005 distance from PT to the scroll margin position. This prevents
18006 try_scrolling from unnecessarily failing when
18007 scroll-conservatively is set to a value slightly larger than the
18008 window height. Clean up the case of PT below the margin at bottom
18009 of window: scroll_max can no longer be INT_MAX. When aggressive
18010 scrolling is in use, don't let point enter the opposite scroll
18011 margin as result of the scroll.
18012 (syms_of_xdisp) <scroll-conservatively>: Document the
18013 threshold of 100 lines for never-recentering scrolling.

18020 (message_log_check_duplicate): Remove parameters `prev_bol' and
18021 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
18022 (redisplay_internal): Remove parameter `preserve_echo_area',
18023 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
18025 * indent.c (Fvertical_motion):
18026 * window.c (window_scroll_pixel_based, Frecenter):
18027 Don't pass `need_y_p' to `move_it_by_lines'.
18029 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
18031 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
18032 steal a few bits to be more compact.
18033 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
18034 Remove unneeded casts.
18036 * bytecode.c (Fbyte_code): CAR and CDR can GC.
18038 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
18040 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
18041 binding" message (bug#7967).
18043 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
18045 Fix more problems found by GCC 4.6.0's static checks.
18047 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
18048 Remove unused local var.
18050 * editfns.c (Fmessage_box): Remove unused local var.
18052 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
18053 (note_mode_line_or_margin_highlight, note_mouse_highlight):
18054 Omit unused local vars.
18055 * window.c (shrink_windows): Omit unused local var.
18056 * menu.c (digest_single_submenu): Omit unused local var.
18057 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
18058 Omit unused local var.
18060 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
18061 Don't assume string length fits in int.
18062 (keyremap_step, read_key_sequence): Use size_t for sizes.

18066 instead of alloca (Bug#8344).
18068 * eval.c (Fbacktrace): Don't assume nargs fits in int.
18069 (Fbacktrace_frame): Don't assume nframes fits in int.
18071 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.

18078 * cm.c (calccost): Turn while-do into do-while, for clarity.
18080 * keyboard.c (syms_of_keyboard): Use the same style as later
18081 in this function when indexing through an array. This also
18082 works around GCC bug 48267.
18084 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
18086 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
18088 * chartab.c (sub_char_table_ref_and_range): Redo for slight
18089 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
18091 * keyboard.c, keyboard.h (num_input_events): Now size_t.
18092 This avoids undefined behavior on integer overflow, and is a bit
18093 more convenient anyway since it is compared to a size_t variable.
18095 Variadic C functions now count arguments with size_t, not int.
18096 This avoids an unnecessary limitation on 64-bit machines, which
18097 caused (substring ...) to crash on large vectors (Bug#8344).

18107 * fns.c (concat): Likewise.
18108 * frame.c (x_set_frame_parameters): Likewise.
18109 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
18110 0 if not found, not -1. All callers changed.
18112 * alloc.c (garbage_collect): Don't assume stack size fits in int.
18113 (stack_copy_size): Now size_t, not int.
18114 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.

18138 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
18139 Vcommand_hook_internal.

18278 Remove unused variable `width'.
18280 2011-03-24 Juanma Barranquero <lekktu@gmail.com>
18282 * w32term.c (x_set_glyph_string_clipping):
18283 Don't pass uninitialized region to CombineRgn.
18285 2011-03-23 Juanma Barranquero <lekktu@gmail.com>
18287 * w32fns.c (x_set_menu_bar_lines): Remove unused variable `olines'.

18307 2011-03-23 Julien Danjou <julien@danjou.info>
18309 * term.c (Fsuspend_tty, Fresume_tty):
18310 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
18311 * window.c (temp_output_buffer_show):
18312 * insdel.c (signal_before_change):
18313 * frame.c (Fhandle_switch_frame):
18314 * fileio.c (Fdo_auto_save):

18317 * cmds.c (internal_self_insert):
18318 * callint.c (Fcall_interactively):
18319 * buffer.c (Fkill_all_local_variables):
18320 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
18322 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
18323 unconditionally since it does the check itself.
18325 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
18327 Fix more problems found by GCC 4.5.2's static checks.
18329 * coding.c (encode_coding_raw_text): Avoid unnecessary test
18330 the first time through the loop, since we know p0 < p1 then.
18331 This also avoids a gcc -Wstrict-overflow warning.
18333 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
18334 leading to a memory leak, possible in functions like
18335 load_charset_map_from_file that can allocate an unbounded number
18336 of objects (Bug#8318).
18338 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
18339 that could (at least in theory) be that large.
18341 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
18342 This is less likely to overflow, and avoids undefined behavior if
18343 overflow does occur. All callers changed. Use strtoul to scan
18344 for the unsigned long integer.
18345 (pint2hrstr): Simplify and tune code slightly.
18346 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
18348 * scroll.c (do_scrolling): Work around GCC bug 48228.
18349 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
18351 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
18352 This also avoids a warning with gcc -Wstrict-overflow.
18353 (validate_x_resource_name): Simplify count usage.
18354 This also avoids a warning with gcc -Wstrict-overflow.
18356 * fileio.c (Fcopy_file): Report error if fchown or fchmod
18359 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
18361 * process.c (Fmake_network_process): Use socklen_t, not int,
18362 where POSIX says socklen_t is required in portable programs.
18363 This fixes a porting bug on hosts like 64-bit HP-UX, where
18364 socklen_t is wider than int (Bug#8277).
18365 (Fmake_network_process, server_accept_connection):
18366 (wait_reading_process_output, read_process_output):
18369 * process.c: Rename or move locals to avoid shadowing.

18379 Make tparam.h and terminfo.c consistent.
18380 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
18381 Include tparam.h instead, since it declares them.
18382 * cm.h (PC): Remove extern decl; tparam.h now does this.
18383 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
18384 * terminfo.c: Include tparam.h, to check interfaces.
18385 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
18386 (tparam): Adjust signature to match interface in tparam.h;
18387 this removes some undefined behavior. Check that outstring and len
18388 are zero, which they always are with Emacs.
18389 * tparam.h (PC, BC, UP): New extern decls.
18391 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
18392 (xftfont_open): Rename locals to avoid shadowing.
18394 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
18395 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
18396 (OTF_TAG_SYM): Omit macro if not needed.

18404 * xml.c (make_dom): Now static.
18406 * composite.c (composition_compute_stop_pos): Rename local to
18408 (composition_reseat_it): Remove unused locals.
18409 (find_automatic_composition, composition_adjust_point): Likewise.
18410 (composition_update_it): Mark var as initialized.
18411 (find_automatic_composition): Mark vars as initialized,
18412 with a FIXME (Bug#8290).

18415 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
18416 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
18417 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
18418 (BUF_DEC_POS): Be more systematic about renaming local temporaries
18419 to avoid shadowing.
18421 * textprop.c (property_change_between_p): Remove; unused.
18423 * intervals.c (interval_start_pos): Now static.
18425 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

18428 Rename locals to avoid shadowing.
18430 * sound.c (wav_play, au_play, Fplay_sound_internal):
18431 Fix pointer signedness.
18432 (alsa_choose_format): Remove unused local var.
18433 (wav_play): Initialize a variable to 0, to prevent undefined
18434 behavior (Bug#8278).
18436 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
18438 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
18440 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
18441 clobbering (Bug#8298).
18442 * sysdep.c (sys_subshell): Likewise.
18443 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
18445 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
18446 This should get cleaned up, so that child_setup has the
18447 same signature on all platforms.
18449 * callproc.c (call_process_cleanup): Now static.
18450 (relocate_fd): Rename locals to avoid shadowing.
18452 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
18454 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
18455 not to be necessary, and produces flickering.
18457 2011-03-20 Glenn Morris <rgm@gnu.org>
18459 * config.in: Remove file.
18461 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
18463 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
18464 are now in src/globals.h.
18465 (syms_of_minibuf): Remove spurious & from previous change.
18467 2011-03-20 Leo Liu <sdl.web@gmail.com>
18469 * minibuf.c (completing-read-function): New variable.
18470 (completing-read-default): Rename from completing-read.
18471 (completing-read): Call completing-read-function.
18473 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
18475 * xfaces.c (Fx_load_color_file):
18476 Read color file from absolute filename (bug#8250).
18478 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
18480 * makefile.w32-in: Update dependencies.
18482 2011-03-17 Eli Zaretskii <eliz@gnu.org>
18484 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.

18491 (sigchld_handler): Now static.
18493 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
18494 That way, the code declares only the vars that it needs.
18495 * s/aix4-2.h (PTY_ITERATION): Declare iteration vars.
18496 * s/cygwin.h (PTY_ITERATION): Likewise.
18497 * s/darwin.h (PTY_ITERATION): Likewise.

18504 (CONSTANTLIM): Remove; unused.
18505 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
18506 Define only if needed.
18508 * unexelf.c (unexec): Name an expression,
18509 to avoid gcc -Wbad-function-cast warning.
18510 Use a different way to cause a compilation error if anyone uses
18511 n rather than nn, a way that does not involve shadowing.
18512 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
18514 * deps.mk (unexalpha.o): Remove; unused.
18516 New file unexec.h, the (simple) interface for unexec (Bug#8267).
18517 * unexec.h: New file.
18518 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
18519 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
18520 Depend on unexec.h.
18521 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
18522 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
18523 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.
18524 Change as necessary to match prototype in unexec.h.
18526 * syntax.c (Fforward_comment, scan_lists): Rename locals to avoid
18528 (back_comment, skip_chars): Mark vars as initialized.

18542 instead of using an uninitialized var.
18543 (font_sort_entities): Mark var as initialized.
18545 * character.h (FETCH_CHAR_ADVANCE): Rename locals to avoid shadowing.
18547 * font.c (font_unparse_xlfd): Don't mix pointers to variables with

18566 (Fdefvar): Rewrite so as not to use empty "else".

18571 * callint.c (quotify_arg, quotify_args): Now static.
18572 (Fcall_interactively): Rename locals to avoid shadowing.
18573 Use const pointer when appropriate.

18579 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
18580 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
18581 some of which prompt warnings from gcc -Wbad-function-cast.
18582 (Fformat_time_string, Fencode_time, Finsert_char):
18583 (Ftranslate_region_internal, Fformat):
18584 Rename or remove local vars to avoid shadowing.
18585 (Ftranslate_region_internal): Mark var as initialized.
18587 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
18590 * lisp.h (eassert): Check that the argument compiles, even if
18591 ENABLE_CHECKING is not defined.
18593 * data.c (Findirect_variable): Name an expression, to avoid
18594 gcc -Wbad-function-cast warning.

18603 Rename locals to avoid shadowing.
18604 (mark_stack): Move local variables into the #ifdef region where
18606 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
18607 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
18609 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
18610 (GC_STRING_CHARS): Remove; not used.
18611 (Fmemory_limit): Cast sbrk's returned value to char *.
18613 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
18614 avoids undefined behavior in theory.
18616 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.

18619 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
18620 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
18621 to use the following functions instead of these macros.
18622 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
18623 EMACS_INT, since callers assume the returned value fits in int.
18624 (upcase1): Likewise, for UPCASE_TABLE.
18625 (uppercasep, lowercasep, upcase): New static inline functions.
18626 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for
18627 the race-condition problem in the old DOWNCASE.
18629 * regex.c (CHARSET_LOOKUP_RANGE_TABLE_RAW, POP_FAILURE_REG_OR_COUNT):
18630 Rename locals to avoid shadowing.
18631 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
18632 (regex_compile, re_search_2, re_match_2_internal):
18633 Remove unused local vars.
18634 (FREE_VAR): Rewrite so as not to use empty "else",
18635 which gcc can warn about.
18636 (regex_compile, re_match_2_internal): Mark locals as initialized.
18637 (RETALLOC_IF): Define only if needed.
18638 (WORDCHAR_P): Likewise. This one is never needed, but is used
18639 only in a comment talking about a compiler bug, so put inside
18640 the #if 0 of that comment.
18641 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
18642 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
18645 * search.c (boyer_moore): Rename locals to avoid shadowing.
18646 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):
18647 (PREV_CHAR_BOUNDARY): Likewise.
18649 * search.c (simple_search): Remove unused var.
18651 * dired.c (compile_pattern): Move decl from here ...

18659 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
18660 Rename locals to avoid shadowing.
18661 (Fvertical_motion): Mark locals as initialized.
18663 * casefiddle.c (casify_object, casify_region): Now static.
18664 (casify_region): Mark local as initialized.
18666 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
18668 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
18669 New macros, so that the caller can use some names other than
18670 gcpro1, gcpro2, etc.
18671 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
18673 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
18674 argument, for consistency with GCPRO2_VAR, etc: it is now the
18675 prefix of the variable, not the variable itself. All uses
18677 * dired.c (directory_files_internal, file_name_completion):
18678 Rename locals to avoid shadowing.
18680 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
18681 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
18682 dired.c's scmp function, had undefined behavior.
18683 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
18684 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
18685 * buffer.h: ... to here, because these macros use current_buffer,
18686 and the new implementation with inline functions needs to have
18687 current_buffer in scope now, rather than later when the macros
18689 (downcase, upcase1): New static inline functions.
18690 (DOWNCASE, UPCASE1): Reimplement using these functions.
18691 This avoids undefined behavior in expressions like
18692 DOWNCASE (x) == DOWNCASE (y), which previously suffered
18693 from race conditions in accessing the global variables
18694 case_temp1 and case_temp2.
18695 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
18696 * lisp.h (case_temp1, case_temp2): Remove their decls.
18697 * character.h (ASCII_CHAR_P): Move from here ...
18698 * lisp.h: ... to here, so that the inline functions mentioned
18699 above can use them.
18701 * dired.c (directory_files_internal_unwind): Now static.
18703 * fileio.c (file_name_as_directory, directory_file_name):
18704 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
18706 (file_name_as_directory): Use const pointers when appropriate.

19130 (BIDI_BOB): Remove unused macro.
19132 * cm.c (cmgoto): Mark variables that gcc -Wuninitialized does not
19133 deduce are never used uninitialized.

19142 Move these decls to tparam.h, and make them agree with what
19143 is actually in tparam.c. The previous trick of using incompatible
19144 decls in different modules does not conform to the C standard.
