1 2012-11-17 Jan Djärv <jan.h.d@swipnet.se>
3 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
4 (ns_select): Return at once if events are held (Bug#12834).
6 2012-11-16 enami tsugutomo <tsugutomo.enami@jp.sony.com>
8 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
9 Needed following 2012-10-20 change. (Bug#12902)
11 2012-11-16 Glenn Morris <rgm@gnu.org>
13 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)

21 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
22 use the same value of thread handle.
23 (start_timer_thread): If the timer thread exited (due to error),
24 clean up by closing the two handles it used. Duplicate the caller
25 thread's handle here, so it gets duplicated only once, when
26 launching the timer thread. Set priority of the timer thread, not
28 (getitimer): Don't duplicate the caller thread's handle here.
31 2012-11-13 Jan Djärv <jan.h.d@swipnet.se>
33 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
36 2012-11-12 Eli Zaretskii <eliz@gnu.org>
38 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
39 passed to pint2str and pint2hrstr to be at most the size of the
40 frame's decode_mode_spec_buffer. This avoids crashes with very
41 large values of FIELD_WIDTH argument to decode_mode_spec.
44 2012-11-07 Martin Rudalics <rudalics@gmx.at>
46 * window.c (Fsplit_window_internal): Set combination limit of
47 new parent window to t iff Vwindow_combination_limit is t;
48 fixing a regression introduced with the change from 2012-09-22.
49 (Fwindow_combination_limit, Fset_window_combination_limit):
52 2012-11-06 Eli Zaretskii <eliz@gnu.org>
54 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
55 amount when the scroll margins are too large. When scrolling
56 backwards in the buffer, give up if cannot reach point or the
57 scroll margin within a reasonable number of screen lines.
58 Fixes point position in window under scroll-up/down-aggressively when
59 point is positioned many lines beyond the window top/bottom.
62 2012-11-05 Eli Zaretskii <eliz@gnu.org>
64 * ralloc.c (relinquish): If real_morecore fails to return memory
65 to the system, don't crash; instead, leave the last heap
66 unchanged and return. (Bug#12774)
68 2012-11-03 Eli Zaretskii <eliz@gnu.org>
70 * lisp.mk: Adjust comments to the fact that term/internal is now
71 loaded from loadup.el.
73 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
74 (msdos_fatal_signal): New function.
75 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
78 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
79 for GCC versions before 4.
80 (emacs_raise): Define to call msdos_fatal_signal.
82 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
83 iterator when starting in the middle of a display or overlay
86 2012-11-03 Jan Djärv <jan.h.d@swipnet.se>
88 * widget.c (resize_cb): New function.
89 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).

97 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
99 Fix crash when using Emacs as commit editor for git (Bug#12697).
100 * callproc.c (setpgrp): Remove macro, as we now use setpgid
101 and it is configured in conf_post.h.
102 (Fcall_process): Don't invoke both setsid and setpgid; the former
103 is enough, if it exists.
104 * callproc.c (Fcall_process, child_setup):
105 * process.c (create_process): Use setpgid.
106 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
108 * dispnew.c (init_display): Initialize the foreground group
109 if we are running a tty display.
110 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
111 * lisp.h (init_foreground_group): New decl.
112 * sysdep.c (inherited_pgroup): New static var.
113 (init_foreground_group, tcsetpgrp_without_stopping)
114 (narrow_foreground_group, widen_foreground_group): New functions.
115 (init_sys_modes): Narrow foreground group.
116 (reset_sys_modes): Widen foreground group.
118 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
120 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
122 2012-10-31 Martin Rudalics <rudalics@gmx.at>
124 * minibuf.c (read_minibuf): Restore current buffer since
125 choose_minibuf_frame calling Fset_frame_selected_window may
126 change it (Bug#12766).
128 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
130 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
132 2012-10-30 Kenichi Handa <handa@gnu.org>
134 * font.c (Ffont_at): If WINDOW is specified and it is not
135 displaying the current buffer, signal an error.
137 2012-10-29 Daniel Colascione <dancol@dancol.org>
139 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
140 In preparation for fixing bug#12739, move these functions from
143 * coding.h, coding.c: ... to here, and compile them only when
144 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
145 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
147 2012-10-28 Eli Zaretskii <eliz@gnu.org>
149 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
150 (timer_loop, getitimer, setitimer): Use it instead of
151 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
153 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
156 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
158 * nsterm.m (NO_APPDEFINED_DATA): New define.
159 (last_appdefined_event_data): New variable
160 (last_appdefined_event): Remove.
161 (ns_select): Initialize t from last_appdefined_event_data instead
162 of [last_appdefined_event data1].
163 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
164 remove last_appdefined_event (Bug#12698).
166 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
168 * frame.c (x_set_font): Catch internal error.
170 2012-10-27 Eli Zaretskii <eliz@gnu.org>
172 Avoid overflow in w32 implementation of interval timers.
173 When possible, for ITIMER_PROF count only times the main thread
175 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
176 'volatile ULONGLONG' types. All the other data which was
177 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
178 (GetThreadTimes_Proc): New typedef.
179 (w32_get_timer_time): New function, returns a suitable time value
181 (timer_loop): Enter critical section when accessing ULONGLONG
182 values of the itimer_data struct, as these accesses are no longer
183 atomic. Call 'w32_get_timer_time' instead of 'clock'.
184 Remove unused variable.
185 (init_timers): Initialize s_pfn_Get_Thread_Times.
186 (start_timer_thread): Don't assign itimer->caller_thread here.
187 (getitimer): Assign itimer->caller_thread here.

193 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
194 mouse movement events if the menu bar is active. This avoids
195 producing a busy "hour-glass" cursor by Windows if the mouse
196 pointer is positioned over a tooltip shown for some menu item.
198 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
200 Don't assume process IDs fit in int.
201 * emacs.c (shut_down_emacs) [!DOS_NT]:
202 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
203 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
204 Use pid_t, not int, to store process IDs, as 'int'
205 is not wide enough on a few platforms (e.g., AIX and IRIX).
207 2012-10-23 Kenichi Handa <handa@gnu.org>
209 The following change is to make face-font-rescale-alist work
210 correctly for non-ASCII fonts.
212 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
213 (font_open_for_lface): Handle Vface_font_rescale_alist.
215 2012-10-23 Chong Yidong <cyd@gnu.org>

232 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
235 * frame.c (Fmouse_position, Fmouse_pixel_position):
236 * xdisp.c (produce_stretch_glyph):
237 Declare local vars only when they're needed.
238 This is clearer and avoids a warning on OpenBSD about unused vars.
239 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
240 This is safer, and avoids OpenBSD warnings about unused vars.
241 * keyboard.c (record_menu_key): Remove unnecessary decl.
242 (poll_timer): Define only if POLL_FOR_INPUT is defined.
243 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
244 as our definition clashes with OpenBSD's.
245 * xfaces.c (load_face_colors, check_lface_attrs)
246 (get_lface_attributes_no_remap, get_lface_attributes)
247 (lface_fully_specified_p, x_supports_face_attributes_p)
248 (tty_supports_face_attributes_p, face_fontset, realize_face)
249 (realize_x_face, realize_tty_face):
250 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
251 merely Lisp_Object *. This is more informative and avoids
252 a warning on OpenBSD about accessing beyond an object's size.
254 2012-10-20 Chong Yidong <cyd@gnu.org>
256 * lread.c (Fload): Doc fix (Bug#12592).

262 2012-10-19 Eli Zaretskii <eliz@gnu.org>
264 * puresize.h (BASE_PURESIZE): Bump the base value to 1700000.
265 See http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00593.html
268 * alloc.c (NSTATICS): Decrease to 0x800.

278 FD_ISSET (Bug#12668).
280 2012-10-18 Daniel Colascione <dancol@dancol.org>
282 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
283 (staticpro): If we run out of staticpro slots, die with an
284 informative error instead of just calling emacs_abort.

333 * w32fns.c (w32_msg_pump): Use XIL instead of casting an integer
334 to Lisp_Object. (Bug#12661)

540 (detect_input_pending_run_timers):
541 * process.c (wait_reading_process_output):
542 Use unsigned for counter where wraparound-on-overflow is desired,
543 since unsigned is guaranteed to have that behavior and signed is not.
544 (read_char): Use ptrdiff_t for string length.
545 (get_input_pending): Remove first argument, since it was always
546 the same pointer-to-int (now pointer-to-boolean) &input_pending,
547 and behave as if it had that value. Return new value of
548 input_pending. All callers changed.
549 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member

566 initializer for PVEC_NORMAL_VECTOR.
568 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
570 Clean out old termopts cruft.

572 * dispnew.c, indent.c, nsterm.m, term.c, xsettings.c, xsmfns.c:
573 Don't include termopts.h.
575 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>

588 (syms_of_nsfont): Remove initialization of Vfonts_in_cache.
590 2012-10-09 Eli Zaretskii <eliz@gnu.org>
592 * w32fns.c (w32_last_error): Change the return value to DWORD, to
593 match what GetLastError returns. Explain why the function is
596 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
597 'is_tooltip_frame', to avoid confusion with its global namesake.
599 2012-10-08 Daniel Colascione <dancol@dancol.org>
601 * xdisp.c (start_hourglass): Call w32_note_current_window when
602 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
603 build that caused Emacs to display the hourglass cursor forever.
605 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
606 which is broken under remote desktop, calculate the number of
607 colors available for a display based on the display's number of
608 planes and number of bits per pixel per plane. (bug#10397).
610 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
612 * nsfont.m (Vfonts_in_cache): New variable.
613 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
614 are used. Add cached fonts to Vfonts_in_cache.
615 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
617 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
619 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
621 (FONT_H): Define after FRAME_H.
622 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
625 * w32term.c: Remove leftover declaration of keyboard_codepage.
627 2012-10-08 Eli Zaretskii <eliz@gnu.org>
629 * makefile.w32-in (FONT_H): Add $(FRAME_H).
630 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
631 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
632 (GLOBAL_SOURCES): Add cygw32.c.

643 (x_to_w32_color): Don't modify the argument, modify a copy instead.
645 2012-10-08 Daniel Colascione <dancol@dancol.org>
647 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
648 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
649 accidental message numbering hole. Change other messages to
652 * w32select.h (HAVE_W32SELECT): Remove.
654 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
655 w32common.h instead of w32heap.h.

665 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
666 (w32_minor_version, w32_build_number, w32_subtype):
667 Remove duplicate definitions.
669 * w32fns.c: Include w32common.h; include w32heap.h only in
672 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
673 Use `report_file_error' instead of `error' in order to better
674 inform users of what went wrong. Increase NTGUI_UNICODE file
675 dialog box file name length to 32k, the maximum allowed by the NT
678 * w32common.h: New file.
679 (ROUND_UP, ROUND_DOWN, get_page_size)

683 (OS_NT, os_subtype, cache_system_info): Move here.
685 * unexw32.c, unexcw.c: Include w32common.h.
687 * emacs.c (main): Use (defined (WINDOWSNT) || defined
688 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
689 to call syms_of_w32select.
691 * cygw32.h: Remove obsolete EXFUN declarations.
693 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
695 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
696 of w32inevt.o from SOME_MACHINE_OBJECTS.
698 2012-10-08 Daniel Colascione <dancol@dancol.org>
700 * image.c: Permanent fix for JPEG compilation issue --- limit
701 jpeglib `boolean' redefinition to Cygwin builds.
703 2012-10-08 Eli Zaretskii <eliz@gnu.org>
705 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
707 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
710 2012-10-08 Daniel Colascione <dancol@dancol.org>
712 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,

717 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
718 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
719 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
720 now a supported configuration.
722 * Makefile.in: consolidate image variables into LIBIMAGE; add
723 W32_OBJ and W32_LIBS. Compile new files.
726 (_DebPrint) declare tracing facility for W32 debugging. We need
727 to unify tracing later.
729 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
730 unconditional use of W32 Unicode functions. Cygwin runs only on
731 100% Unicode operating systems.
733 * cygw32.c: New file. Define Cygwin-specific facilities.
734 (Fcygwin_convert_path_to_windows)
735 (Fcygwin_convert_path_from_windows): New user functions for
736 accessing Cygwin path-munging routines.
738 * cygw32.h: New file.
739 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
740 UTF-16LE strings temporarily inside non-Lisp-visible string
743 (w32_strerror): Just what it says on the tin.
745 * emacs.c: Make the NS fork-then-exec code for daemon-launching
746 also run for Cygwin; both systems have the same problem with using
747 GUI facilities in a forked child. Also call syms_of_cygw32,
748 syms_of_w32select in correct places.
750 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
751 needs fork-then-exec for daemon launching.
753 * font.h: Include frame.h.
755 * image.c: Use the image library cache machinery only when we're
756 compiling for native WINDOWSNT; Cygwin can use shared libraries
757 like any other Unixlike system.
759 * keyboard.c: Clarify a comment regarding the input loop.
761 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
762 functions directly instead of trying to detect at runtime that our
763 host operating system supports them. We make this change for two
764 reasons: Cygwin lacks support for the multibyte character
765 conversion functions used by the legacy menu code, and Cygwin
766 never needs to rely on non-Unicode APIs.
768 * unexw32.c (hinst): Declare extern.
770 * w32.c: Change header order;
771 (w32_strerror): Move to w32fns.c because we need it for
772 non-WINDOWSNT builds.
774 * w32.h: Add #error macro to make sure we don't include w32.h for
775 Cygwin builds. Remove w32select declarations.
777 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
778 w32fns.c. w32console.c is WINDOWSNT-only.
780 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
781 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
783 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
784 (w32_major_version, w32_minor_version, w32_build_number)
785 (os_subtype, sound_type): Define here
786 (w32_defined_color): Make color parameter const for consistency
787 with other _defined_color functions.
788 (w32_createwindow): Unconditionally call w32_init_class instead of
789 doing so only when hprevinst is non-NULL. Plumbing hprevinst
790 through the code is complex and unnecessary because class
791 registration is practically free.
792 (w32_name_of_message): New EMACSDEBUG-only function.
793 (Fset_message_beep): Move here
794 (Fx_open_connection): Require that the display name for Windows be
795 "w32" for consistency, emacsclient disambiguation, and maybe, one
796 day, multi-window-system support.
797 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
798 Cygwin files for W32 GUI facilities, since these clearly don't
801 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
802 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
803 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
804 (w32_last_error): Remove.
806 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
808 * w32heap.c (syspage_mask): Declare here.
809 (cache_system_info): Remove.
811 * w32inevt.c (faked_key): Define globally, not statically.
812 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
813 (w32_console_toggle_lock_key): Move to w32fns.c.
815 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
817 * w32proc.c (_DebPrint): Move to w32fns.c.
818 * w32select.c: Include string.h, stdio.h for Cygwin.
819 * w32select.h: New File.
821 * w32term.c: Include io.h for non-CYGWIN builds; needed for
823 (w32_message_fd): New variable. Under Cygwin, holds the file
824 descriptor the system used to tell us about pending thread
827 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
828 that prevented compilation under non-WINDOWSNT systems.
830 (w32_initialize): Open /dev/windows and assign it to
831 w32_message_fd. Provide w32 feature.
833 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
834 (WM_EMACS_INPUT_READY): add.
835 (prepend_msg, w32_message_fd): Declare globally.
838 (keyboard_handle): Use only when WINDOWSNT.
839 (notify_msg_ready): New function. Posts a message to the main
840 thread's message queue under CYGWIN, which wakes up the main
841 thread from select(2) by making the /dev/windows file descriptor
842 ready. Under WINDOWSNT, it sets an event the same way the old
845 (post, prepend_msg): Actually call notify_msg_ready instead of
846 setting the input event directly.
848 2012-10-07 Eli Zaretskii <eliz@gnu.org>
850 * ralloc.c (relinquish): If a heap is ready to be relinquished,
851 but it still has blocs in it, don't return it to the system,
852 instead of aborting. (Bug#12402)
854 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
856 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
858 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
859 MAC_OS_X_VERSION_10_6.
860 (syms_of_nsterm): Remove comment about Panther and above for
862 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
863 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
864 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
866 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
867 MAC_OS_X_VERSION_10_4.
869 * nsmenu.m (fillWithWidgetValue:): Remove code for <
870 MAC_OS_X_VERSION_10_2.
872 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
874 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
875 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
877 * nsterm.m (ns_in_resize): Remove (Bug#12479).
878 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
879 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
880 Remove ns_in_resize check.
881 (ns_clear_frame_area): Remove resize handle code.
883 * nsfns.m (ns_in_resize): Remove.
884 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
885 Remove ns_in_resize check.
887 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
889 Improve sys_siglist detection.
890 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
891 defined as a macro, as is done in Solaris.
892 (sys_siglist_entries): New macro.
893 (save_strsignal): Use it.
894 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
895 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
897 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
899 * nsfns.m (Fx_create_frame): Call x_default_parameter with
900 fullscreen/Fullscreen.
902 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
905 * nsterm.m (x_make_frame_visible): Check for fullscreen.
906 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
907 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
908 (windowDidResize:): Check for correct window if old style fullscreen.
909 Capitalize word in comment. Remove incorrect comment.
910 (initFrameFromEmacs:): tbar_height renamed tibar_height.
911 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
912 error in drawing background.
913 (toggleFullScreen:): Remove comment. Rearrange calls.
914 Set toolbar values to zero, save old height in tobar_height.
915 Restore tool bar height when leaving fullscreen.
916 (canBecomeMainWindow): New function.
918 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
920 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
922 2012-10-05 Eli Zaretskii <eliz@gnu.org>
924 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
926 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
927 that time stamps of directories could also be changed.
928 Don't request the too broad GENERIC_WRITE, only the more restrictive
929 FILE_WRITE_ATTRIBUTES access rights.
931 * fileio.c (Fset_file_times): Special-case ignoring errors for
932 directories only on MSDOS, not on MS-Windows.
934 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
936 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
938 2012-10-04 Eli Zaretskii <eliz@gnu.org>
940 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
941 see whether CreateFile failed.
943 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
945 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
946 to avoid similar races.
947 * keyboard.c (pending_signals): Now bool, not int.
949 Port timers to OpenBSD, plus check for timer failures.
950 OpenBSD problem reported by Han Boetes.
951 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
953 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
954 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
955 like OpenBSD, which has timer_settime but does not declare it.
956 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
957 whether to use itimerspec-related primitives. All uses of
958 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
960 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
962 * profiler.c (handle_profiler_signal): Fix a malloc race
963 that caused Emacs to hang on Fedora 17 when profiling Lisp.
965 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
967 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
969 2012-10-02 Eli Zaretskii <eliz@gnu.org>
971 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
972 consistent with the change in return value of 'safe_strsignal'.
974 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
976 Prefer plain 'static' to 'static inline' (Bug#12541).
977 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
978 (bidi_set_sor_type, bidi_push_embedding_level)
979 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)

984 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
985 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
986 Now 'static', not 'static inline'.
988 Count overruns when profiling; change units to ns.
989 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
990 Give extra weight to samples after overruns, to attempt to count
991 the time more accurately.
992 (setup_cpu_timer): Change sampling interval units from ms to ns, since
993 the underlying primitives nominally do ns.
994 (Fprofiler_cpu_start): Document the change. Mention that
995 the sampling intervals are only approximate.
997 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
999 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
1001 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
1002 case for the special 0 coding-system.
1004 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
1005 (Fmake_overlay): Remove redundant tests.
1006 (fix_start_end_in_overlays): Remove redundant recentering.
1008 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
1010 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
1011 Update dependencies.
1013 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
1015 Fix a malloc race condition involving strsignal.
1016 A signal can arrive in the middle of a malloc, and Emacs's signal
1017 handler can invoke strsignal, which can invoke malloc, which is
1018 not portable. This race condition bug makes Emacs hang on GNU/Linux.
1019 Fix it by altering the signal handler so that it does not invoke
1021 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
1022 * process.c (status_message): Use const pointer, in case strsignal
1023 is #defined to safe_strsignal.
1024 * sysdep.c (sys_siglist, init_signals): Always define and
1025 initialize a substitute sys_siglist if the system does not define
1026 one, even if HAVE_STRSIGNAL.
1027 (safe_strsignal): Rename from strsignal. Always define,
1028 using sys_siglist. Return a const pointer.
1029 * syssignal.h (safe_strsignal): New decl.
1030 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
1032 2012-10-01 Eli Zaretskii <eliz@gnu.org>
1034 * w32proc.c (timer_loop): Fix code that waits for timer
1035 expiration, to avoid high CPU usage.
1037 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
1039 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
1040 (sweep_weak_table): Remove redundant prototypes.
1042 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
1044 * emacs.c: Move the inclusion of TERM_HEADER after including
1045 windows.h on WINDOWSNT. This avoids compilation problems with
1048 2012-10-01 Eli Zaretskii <eliz@gnu.org>
1050 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
1051 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
1052 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
1053 as the previous version used 'void *'.
1055 * ralloc.c (ROUNDUP): Fix last change.
1056 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
1059 * w32proc.c <disable_itimers>: New static flag.
1060 (init_timers): Initialize it to zero, after creating the critical
1061 sections used by the timer threads.
1062 (term_timers): Set to 1 before deleting the critical sections.
1063 (getitimer, setitimer): If disable_itimers is non-zero, return an
1064 error indication without doing anything. Reported by Fabrice
1065 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
1066 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
1068 [!HAVE_SETITIMER]: Behave as the previous version that didn't
1071 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
1072 term_ntproc after all the other bookkeeping, to get timers working
1073 as long as possible.
1075 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
1077 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
1078 Suggested by Juri Linkov in
1079 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
1081 Prefer plain 'static' to 'static inline' (Bug#12541).
1082 With static functions, modern compilers inline pretty well by
1083 themselves; advice from programmers often hurts as much as it helps.
1084 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
1085 this change shrinks the text size of the Emacs executable by 1.1%
1086 without affecting CPU significantly in my benchmark.

1166 (bidi_copy_it): Do the whole copy with a single memcpy.
1167 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
1169 Revert the FOLLOW-SYMLINKS change for file-attributes.
1170 Doing it right would require several changes to Tramp, and there's
1171 not enough time to get that tested before the freeze today.
1172 * dired.c (directory_files_internal, Ffile_attributes):
1175 * frame.c (x_report_frame_params): Port better to wider ints.
1176 Do not assume that EMACS_UINT is the same width as uprintmax_t,

1209 * w32.c (init_environment, get_emacs_configuration): Support AMD64
1211 (init_ntproc): Cast arguments of _open_osfhandle to intptr_t, for
1212 compatibility with x64.
1214 * vm-limit.c (lim_data): Now size_t.
1215 (check_memory_limits): Adjust prototypes of real_morecore and
1216 __morecore to receive argument of type ptrdiff_t. Use size_t for
1217 five_percent and data_size.
1219 * unexw32.c: Use DWORD_PTR instead of DWORD for file-scope
1220 variables, for compatibility with x64.

1243 value of FRAME_X_WINDOW, to fit a 64-bit pointer on 64-bit Windows

1369 Profiler improvements: more-accurate timers, overflow checks.
1370 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
1371 signal.h, setjmp.h. Include systime.h instead.
1372 (saturated_add): New function.
1373 (record_backtrace, current_sample_interval): Use EMACS_INT, not size_t.

1379 All uses changed to store the new value.
1380 (handle_profiler_signal): Rename from sigprof_handler_1,
1381 for consistency with other handlers. Do not check whether
1382 cpu_log is a hash-table if garbage collecting, since it
1383 doesn't matter in that case.

1385 for consistency with other handlers.
1386 (setup_cpu_timer): New function, with much of what used to be in
1387 Fprofiler_cpu_start. Check for out-of-range argument.
1388 Prefer timer_settime if available, and prefer
1389 thread cputime clocks, then process cputime clocks, then
1390 monotonic clocks, to the old realtime clock. Use make_timeval
1391 to round more-correctly when falling back to setitimer.
1392 (Fprofiler_cpu_start): Use it.
1393 (Fprofiler_cpu_stop): Prefer timer_settime if available.
1394 Don't assume that passing NULL as the 2nd argument of setitimer
1395 is the same as passing a pointer to all-zero storage.
1396 Ignore SIGPROF afterwards.
1397 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
1398 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
1399 non-fatal signal handlers. Ignore SIGPROF on startup.
1400 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
1401 in profiler.c, since sysdep.c now uses it.
1403 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.

1458 * charset.c, charset.h (maybe_unify_char): Now static.
1459 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
1460 Since this stuff is now private to charset.c, there's no need for
1461 a public macro and no need to inline by hand.

1490 2012-09-25 Juanma Barranquero <lekktu@gmail.com>
1492 * makefile.w32-in ($(BLD)/callproc.$(O)): Update dependencies.
1494 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>
1496 Prefer POSIX timers if available.
1497 They avoid a race if the timer is too close to the current time.
1498 * atimer.c (alarm_timer, alarm_timer_ok) [SIGEV_SIGNAL]: New static vars.
1499 (set_alarm) [SIGEV_SIGNAL]: Use POSIX timers if available.
1500 (init_atimer) [SIGEV_SIGNAL]: Initialize them.
1502 2012-09-25 Eli Zaretskii <eliz@gnu.org>

1507 STRING_CHAR_ADVANCE.
1509 2012-09-25 Juanma Barranquero <lekktu@gmail.com>
1511 Move Vlibrary_cache to emacs.c and reset before dumping.
1513 * lisp.h (reset_image_types): Declare.
1514 [WINDOWSNT] (Vlibrary_cache): Declare.
1516 * image.c (reset_image_types): New function.
1518 * emacs.c [WINDOWSNT] (Vlibrary_cache): Move from w32.c.

1525 * w32.h (Vlibrary_cache): Do not declare.
1527 2012-09-25 Eli Zaretskii <eliz@gnu.org>
1529 * w32proc.c (sys_signal): Handle all signals defined by the
1530 MS-Windows runtime, not just SIGCHLD. Actually install the signal
1531 handlers for signals supported by Windows. Don't override
1532 term_ntproc as the handler for SIGABRT.
1533 (sigaction): Rewrite to call sys_signal instead of duplicating its
1535 (sys_kill): Improve commentary.
1537 * w32.c (term_ntproc): Accept (and ignore) one argument, for
1538 consistency with a signature of a signal handler. All callers
1540 (init_ntproc): Accept an argument DUMPING. If dumping, don't
1541 install term_ntproc as a signal handler for SIGABRT, as that
1542 should be done by the dumped Emacs.
1544 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
1546 * w32select.c (term_w32select): Protect against repeated
1547 invocation by setting clipboard_owner to NULL after calling

1551 and term_ntproc to their modified signatures.
1553 * character.c (char_string, string_char): Remove calls to
1554 MAYBE_UNIFY_CHAR. See the discussion starting at
1555 http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00433.html
1558 2012-09-25 Chong Yidong <cyd@gnu.org>
1560 * xdisp.c (mode_line_inverse_video): Delete obsolete variable.
1562 2012-09-24 Stefan Monnier <monnier@iro.umontreal.ca>
1564 * bytecode.c (exec_byte_code): Signal an error instead of aborting,
1565 when encountering an unknown bytecode.
1567 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
1569 image.c, indent.c: Use bool for booleans.
1570 * dispextern.h (struct image_type): Members valid_p, load, init
1571 now return bool, not int. All uses changed.
1572 * image.c: Omit unnecessary static decls.
1573 (x_create_bitmap_mask, x_build_heuristic_mask):
1574 Return void, not int, since callers don't care about the return value.

1603 Use bool for booleans.
1605 2012-09-24 Chong Yidong <cyd@gnu.org>
1607 * chartab.c (Fset_char_table_default): Obsolete function removed.
1609 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
1611 Move pid_t related decls out of lisp.h.
1612 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
1613 (interruptible_wait_for_termination):
1614 Move these decls from lisp.h to syswait.h, since they use pid_t.
1615 Needed on FreeBSD; see Herbert J. Skuhra in
1616 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
1617 * callproc.c: Include syswait.h.
1619 gnutls.c, gtkutil.c: Use bool for boolean.

1634 * nsmenu.m (ns_update_menubar):
1635 * nsmenu.m, w32menu.c, xmenu.c (set_frame_menubar):
1636 * xfns.c (Fx_show_tip) [USE_GTK]:
1637 Use bool for boolean.
1638 * gtkutil.c (xg_update_frame_menubar):
1639 * xmenu.c (update_frame_menubar):
1640 Return void, not int, since caller ignores return value.
1641 * gtkutil.c (xg_change_toolbar_position):
1644 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
1646 * makefile.w32-in (BLOCKINPUT_H): Remove.

1663 2012-09-23 Eli Zaretskii <eliz@gnu.org>
1665 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
1666 fatal_error_backtrace.
1668 * w32proc.c (sys_kill): Undo last change: don't do anything when
1669 invoked to deliver SIGABRT to our own process. This is now
1670 handled by emacs_raise.
1672 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
1674 * w32term.c (w32_read_socket): Remove leftover reference to
1675 interrupt_input_pending.
1677 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
1679 Do not use SA_NODEFER.
1680 Problem reported by Dani Moncayo in
1681 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
1683 * sysdep.c (emacs_abort): Do not reset signal handler.
1684 * emacs.c (terminate_due_to_signal): Reset signal handler here.
1685 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
1686 wanted even on POSIXish hosts, and it doesn't work on Windows.
1688 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
1690 * xterm.c (x_term_init): Call fixup_locale before and after calling
1691 gtk_init (Bug#12392).
1693 2012-09-23 Chong Yidong <cyd@gnu.org>
1695 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
1696 Vdynamic_library_alist.
1698 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
1699 (Fgnutls_available_p): Caller changed.
1701 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
1702 (Flibxml_parse_xml_region): Likewise.
1704 * dispextern.h (struct image_type): Remove arg from init function.
1706 * image.c (Finit_image_library, lookup_image_type)
1707 (define_image_type): Remove now-unneeded second arg.
1708 (init_xpm_functions, init_png_functions, init_jpeg_functions)
1709 (init_tiff_functions, init_gif_functions, init_svg_functions):
1710 Arglist and w32_delayed_load calling convention changed.
1711 (gs_type): Remove init_gs_functions; there is no such function.
1712 (valid_image_p, make_image): Fix caller to lookup_image_type.
1714 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
1716 Simplify and avoid signal-handling races (Bug#12471).
1718 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
1719 Avoid recursive loop if there's a fatal error in the function itself.
1720 * atimer.c (pending_atimers):
1721 * blockinput.h: Don't include "atimer.h"; no longer needed.
1722 (interrupt_input_pending): Remove. All uses removed.
1723 pending_signals now counts both atimers and ordinary interrupts.
1724 This is less racy than having three separate pending-signal flags.
1725 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
1727 Rename from their upper-case counterparts BLOCK_INPUT,
1728 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
1729 INPUT_BLOCKED_P, and turn into functions. All uses changed.
1730 This makes it easier to access volatile variables more accurately.
1731 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
1732 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
1733 that's more reliable if the code is buggy and sets
1734 interrupt_input_blocked to a negative value. All uses changed.
1735 * atimer.c (deliver_alarm_signal):
1736 Remove. No need to deliver this to the parent; any thread can
1737 handle this signal now. All uses replaced by underlying handler.
1738 * atimer.c (turn_on_atimers):
1739 * dispnew.c (handle_window_change_signal):
1740 * emacs.c (handle_danger_signal):
1741 * keyboard.c (kbd_buffer_get_event):
1742 Don't reestablish signal handler; not needed with sigaction.
1743 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
1745 Rework to avoid unnecessary accesses to volatile variables.
1746 (UNBLOCK_INPUT_TO): Now a function.
1747 (totally_unblock_input, unblock_input): New decls.
1748 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
1749 (init_data): Remove. Necessary stuff now done in init_signal.
1750 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
1751 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
1752 (fatal_error_code): Remove; no longer needed.
1753 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
1754 it doesn't always backtrace. All uses changed. No need to reset
1755 signal to default, since sigaction and/or die does that for us now.
1756 Use emacs_raise (FOO), not kill (getpid (), FOO).
1757 (main): Check more-accurately whether we're dumping.
1758 Move fatal-error setup to sysdep.c
1759 * floatfns.c: Do not include "syssignal.h"; no longer needed.
1760 * gtkutil.c (xg_get_file_name, xg_get_font):
1761 Remove no-longer-needed signal-mask manipulation.
1762 * keyboard.c, process.c (POLL_FOR_INPUT):
1763 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
1764 * keyboard.c (read_avail_input): Remove.
1765 All uses replaced by gobble_input.
1766 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
1767 (kbd_buffer_store_event_hold, gobble_input):
1768 (record_asynch_buffer_change) [USABLE_SIGIO]:
1769 (store_user_signal_events):
1770 No need to mess with signal mask.
1771 (gobble_input): If blocking input and there are terminals, simply
1772 set pending_signals to 1 and return. All hooks changed to not
1773 worry about whether input is blocked.
1774 (process_pending_signals): Clear pending_signals before processing
1775 them, in case a signal comes in while we're processing.
1776 By convention callers now test pending_signals before calling us.
1777 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
1778 New functions, to support changes to blockinput.h.
1779 (handle_input_available_signal): Now extern.
1780 (reinvoke_input_signal): Remove. All uses replaced by
1782 (quit_count): Now volatile, since a signal handler uses it.
1783 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
1784 All callers changed. Block SIGINT only if not already blocked.
1785 Clear sigmask reliably, even if Fsignal returns, which it can.
1786 Omit unnecessary accesses to volatile var.
1787 (quit_throw_to_read_char): No need to restore sigmask.
1788 * keyboard.c (gobble_input, handle_user_signal):
1789 * process.c (wait_reading_process_output):
1790 Call signal-handling code rather than killing ourselves.
1791 * lisp.h: Include <float.h>, for...
1792 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
1793 (pending_signals): Now volatile.
1794 (syms_of_data): Now const if IEEE floating point.
1795 (handle_input_available_signal) [USABLE_SIGIO]:
1796 (terminate_due_to_signal, record_child_status_change): New decls.
1797 * process.c (create_process): Avoid disaster if memory is exhausted
1798 while we're processing a vfork, by tightening the critical section
1800 (send_process_frame, process_sent_to, handle_pipe_signal)
1801 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
1803 (send_process): No need for setjmp/longjmp any more, since the
1804 SIGPIPE stuff is now gone. Instead, report an error if errno
1806 (record_child_status_change): Now extern. PID and W are now args.
1807 Return void, not bool. All callers changed.
1808 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
1809 Remove. All uses removed. This bug should be fixed now in a
1811 (wait_for_termination_1): Use waitpid rather than sigsuspend,
1812 and record the child status change directly. This avoids the
1813 need to futz with the signal mask.
1814 (process_fatal_action): Move here from emacs.c.
1815 (emacs_sigaction_flags): New function, containing
1816 much of what used to be in emacs_sigaction_init.
1817 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
1818 caught by emacs, to make races less likely.
1819 (deliver_process_signal): Rename from handle_on_main_thread.
1821 (BACKTRACE_LIMIT_MAX): Now at top level.
1822 (thread_backtrace_buffer, threadback_backtrace_pointers):
1824 (deliver_thread_signal, deliver_fatal_thread_signal):
1825 New functions, for more-accurate delivery of thread-specific signals.
1826 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
1827 (deliver_arith_signal): Handle in this thread, not
1828 in the main thread, since it's triggered by this thread.
1829 (maybe_fatal_sig): New function.
1830 (init_signals): New arg DUMPING so that we can be more accurate
1831 about whether we're dumping. Caller changed.
1832 Treat thread-specific signals differently from process-general signals.
1833 Block all signals while handling fatal error; that's safer.
1834 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
1836 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
1837 Ignore SIGPIPE unless batch.
1838 (emacs_backtrace): Output backtrace for the appropriate thread,
1839 which is not necessarily the main thread.
1840 * syssignal.h: Include <stdbool.h>.
1841 (emacs_raise): New macro.
1842 * xterm.c (x_connection_signal): Remove; no longer needed
1843 now that we use sigaction.
1844 (x_connection_closed): No need to mess with sigmask now.
1845 (x_initialize): No need to reset SIGPIPE handler here, since
1846 init_signals does this for us now.
1848 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
1850 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
1851 background rect may be larger (Bug#12245).
1853 2012-09-23 Chong Yidong <cyd@gnu.org>
1855 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
1857 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
1859 * .gdbinit: Just stop at fatal_error_backtrace.
1860 See Stefan Monnier's request in
1861 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
1862 Remove no-longer-used query of system type.
1864 2012-09-22 Chong Yidong <cyd@gnu.org>
1866 * search.c (Freplace_match): Doc fix (Bug#12325).
1868 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
1870 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
1871 (Fline_end_position): Doc fix.
1873 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
1875 2012-09-22 Chong Yidong <cyd@gnu.org>
1877 * dispextern.h (struct image_type): Add new slot, storing a type
1878 initialization function.
1880 * image.c (define_image_type): Call the image initializer function
1881 if it is defined. Arguments and return value changed.
1882 (valid_image_p, make_image): Callers changed.
1883 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
1884 (gif_type, imagemagick_type, svg_type, gs_type):
1885 Add initialization functions.
1886 (Finit_image_library): Call lookup_image_type.
1887 (CHECK_LIB_AVAILABLE): Macro deleted.
1888 (lookup_image_type): Call define_image_type here, rather than via
1889 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
1890 (syms_of_image): Move define_image_type calls for xbm_type and
1891 pbm_type to lookup_image_type.
1893 2012-09-22 Eli Zaretskii <eliz@gnu.org>
1895 * keyboard.c (timer_check_2): Move calculation of 'timers' and
1896 'idle_timers' from here ...
1897 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
1898 lists, to avoid infloops when the timer does something stupid,
1899 like reinvoke itself with the same or smaller time-out.
1902 2012-09-22 Martin Rudalics <rudalics@gmx.at>
1904 * window.c (Fsplit_window_internal): Handle only Qt value of
1905 Vwindow_combination_limit separately.
1906 (Qtemp_buffer_resize): New symbol.
1907 (Vwindow_combination_limit): New default value.
1910 2012-09-22 Eli Zaretskii <eliz@gnu.org>
1912 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
1913 the new overlay string. (Bug#10159)
1915 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
1917 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
1918 or that fprintf is async-signal-safe. POSIX doesn't require
1921 2012-09-22 Chong Yidong <cyd@gnu.org>
1923 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
1926 2012-09-22 Kenichi Handa <handa@gnu.org>
1928 * composite.c (composition_reseat_it): Handle the case that a
1929 grapheme cluster is not covered by a single font (Bug#12352).
1931 2012-09-21 Chong Yidong <cyd@gnu.org>
1933 * image.c (define_image_type): Avoid adding duplicate types to
1934 image_types (Bug#12463). Suggested by Jörg Walter.
1936 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1938 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
1939 (print_load_command_name): Add case LC_DATA_IN_CODE.
1940 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
1942 2012-09-21 Glenn Morris <rgm@gnu.org>
1944 * eval.c (Frun_hook_with_args_until_success)
1945 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
1947 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
1949 * fileio.c (Ffile_selinux_context): Only call freecon when
1950 lgetfilecon succeeded.
1951 (Fset_file_selinux_context): Likewise. (Bug#12444)
1953 2012-09-21 Eli Zaretskii <eliz@gnu.org>
1955 * xdisp.c (try_window_reusing_current_matrix): Under bidi
1956 reordering, locate the cursor by calling set_cursor_from_row; if
1957 that fails, clear the desired glyph matrix before returning a
1958 failure indication to the caller. Fixes leaving garbled display
1959 when fast scrolling with a down-key. (Bug#12403)
1960 (compute_stop_pos_backwards): Fix a typo that caused crashes while
1961 scrolling through multibyte text.
1963 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
1965 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
1966 calling mark_vectorlike since that's the one that marks the window.
1967 (mark_discard_killed_buffers): Mark the final cdr.
1968 * window.h (struct window): Move prev/next_buffers to the
1969 non-standard fields.
1970 * window.c (make_window): Initialize prev/next_buffers manually.
1972 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
1974 Omit unused arg EXPECTED from socket hooks.
1975 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
1976 * nsterm.m (ns_term_init):
1977 * termhooks.h (struct terminal.read_socket_hook):
1978 * w32inevt.c (w32_console_read_socket):
1979 * w32term.c (w32_read_socket):
1980 * xterm.c (XTread_socket):
1981 Omit unused arg EXPECTED. All callers changed.
1982 (store_user_signal_events): Return void, not int, since callers no
1983 longer care about the return value. All uses changed.
1985 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
1987 * w32gui.h (XParseGeometry): Do not declare.
1989 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
1991 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
1992 Ignore 'expected'. See Eli Zaretskii in
1993 <http://bugs.gnu.org/12471#8> (last line).
1995 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
1996 (XParseGeometry): Now static. Substitute extremal values for
1997 values that are out of range.
1999 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
2001 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
2003 * nsfns.m (XParseGeometry): Remove.
2004 (Fx_create_frame): Call x_set_offset to correctly interpret
2005 top_pos in geometry.
2007 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
2008 (Fx_parse_geometry): If there is a space in string, call
2009 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
2011 2012-09-17 Eli Zaretskii <eliz@gnu.org>
2013 * search.c (scan_buffer): Use character positions in calls to
2014 region_cache_forward and region_cache_backward, not byte
2015 positions. (Bug#12196)
2017 * w32term.c (w32_read_socket): Set pending_signals to 1, like
2018 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
2020 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
2021 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
2022 emacs_blocked_malloc, now deleted.
2024 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
2026 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
2027 The workaround was for improving performance on Solaris 2.4, but
2028 is getting in the way now. Emacs will still work if someone is
2029 still running Solaris 2.4 in a museum somewhere; Sun dropped
2030 support for Solaris 2.4 in 2003.
2031 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
2032 * process.c (create_process) [HAVE_WORKING_VFORK]:
2033 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
2034 since Emacs no longer uses vfork on that platform.
2036 2012-09-17 Glenn Morris <rgm@gnu.org>
2038 * emacs.c: Use COPYRIGHT.
2040 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
2042 Remove configure's --without-sync-input option (Bug#12450).
2043 When auditing signal-handling in preparation for cleaning it up,
2044 I found that SYNC_INPUT has race conditions and would be a real
2045 pain to fix. Since it's an undocumented and deprecated
2046 configure-time option, now seems like a good time to remove it.
2047 Also see <http://bugs.gnu.org/11080#16>.
2048 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
2049 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
2050 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
2051 (malloc_hysteresis):
2052 (check_depth) [XMALLOC_OVERRUN_CHECK]:
2053 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
2054 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
2055 (dont_register_blocks, bytes_used_when_reconsidered)
2056 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
2057 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
2058 [!SYSTEM_MALLOC && !SYNC_INPUT]:
2059 Remove. All uses removed.
2060 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
2061 implementation, one that depends on whether the new macro
2062 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
2064 * atimer.c (run_timers, handle_alarm_signal):
2065 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
2066 (handle_async_input, process_pending_signals)
2067 (handle_input_available_signal, init_keyboard):
2068 * nsterm.m (ns_read_socket):
2069 * process.c (wait_reading_process_output):
2070 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
2071 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
2073 * xterm.c (XTread_socket):
2075 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
2076 * eval.c (handling_signal): Remove. All uses removed.
2077 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
2078 All uses replaced with the SYNC_INPUT version.
2079 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
2081 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
2084 * font.c (Ffont_shape_gstring): Remove unused local.
2086 2012-09-16 Glenn Morris <rgm@gnu.org>
2088 * Makefile.in (clean): No longer run nextstep's clean.
2090 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
2092 (ns-app): Move here from ns.mk, and simplify.
2093 (clean): Simplify nextstep entry.
2094 * ns.mk: Remove file.
2096 2012-09-17 Kenichi Handa <handa@gnu.org>
2098 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
2099 not covert the last few charactes.
2101 2012-09-16 Kenichi Handa <handa@gnu.org>
2103 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
2104 here, but just check the validity of glyphs in the glyph-string.
2106 2012-09-16 Martin Rudalics <rudalics@gmx.at>
2108 * window.c (Fwindow_parameter, Fset_window_parameter):
2109 Accept any window as argument (Bug#12452).
2111 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
2113 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
2114 to ns_term_init to avoid memory leak.
2116 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
2117 explicit retain/release.
2118 (ns_term_init): Only allow one display. Initialize outerpool and
2121 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
2123 Port _setjmp fix to POSIXish hosts as well as Microsoft.
2124 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
2125 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
2126 the Microsoft problem in a different way, by altering ../nt/config.nt.
2128 2012-09-15 Eli Zaretskii <eliz@gnu.org>
2143 * w16select.c: Remove inclusion of setjmp.h, as it is now included
2144 by lisp.h. This completes removal of setjmp.h inclusion
2145 erroneously announced in the previous commit. (Bug#12446)
2147 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
2150 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
2151 not defined as a macro. The latter happens on MS-Windows.
2154 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
2156 Port better to POSIX hosts lacking _setjmp (Bug#12446).
2157 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
2158 Some instances of '#include <setjmp.h>' removed, if the
2159 only reason for the instance was because "lisp.h" was included.
2160 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
2161 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
2162 and _longjmp with the new symbols. Emacs already uses _setjmp if
2163 available, so this change affects only POSIXish hosts that have
2164 sigsetjmp but not _setjmp, such as some versions of Solaris and
2165 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
2166 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
2167 (png_load_body) [HAVE_PNG]:
2168 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
2169 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
2170 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
2171 since PNG requires jmp_buf. This is the only exception to the
2172 general rule that we now use sys_setjmp and sys_longjmp.
2173 This exception is OK since this code does not change the signal
2174 mask or longjmp out of a signal handler.
2176 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
2178 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
2179 Include "syssignal.h", for 'main_thread'.
2181 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
2183 Avoid out-of-range marker position (Bug#12426).
2184 * insdel.c (replace_range, replace_range_2):
2185 Adjust markers before overlays, as suggested by comments.
2186 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
2187 Remove redundant check before calling offset_intervals.
2189 2012-09-14 Martin Rudalics <rudalics@gmx.at>
2191 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
2192 current buffer (Bug#12387).
2194 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
2196 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
2198 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
2200 Use a more backwards-compatible timer format (Bug#12430).
2201 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
2202 vector element, not from the 4th, since PSECS is now at the end.
2203 (Fcurrent_idle_time): Doc fix.
2205 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
2207 Function to mark objects and remove killed buffers at once.
2208 * alloc.c (discard_killed_buffers): Rename to ...
2209 (mark_discard_killed buffers) ... new name. Add marking
2210 of remaining objects. Fix comment. Adjust users.
2211 (mark_object): Do not touch frame buffer lists here.
2212 * frame.c (delete_frame): Reset frame buffer lists here.
2214 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
2216 Better workaround for GNOME bug when --enable-gcc-warnings.
2217 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
2218 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
2219 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
2221 Simplify SIGIO usage (Bug#12408).
2222 The code that dealt with SIGIO was crufty and confusing, e.g., it
2223 played tricks like "#undef SIGIO" but these tricks were not used
2224 consistently. Simplify mostly by not #undeffing standard symbols,
2225 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
2226 or not as we please) rather than "defined SIGIO" (standard symbol
2227 that we probably shouldn't #undef).
2228 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
2229 Modules that need it can include it.
2230 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
2231 * dispextern.h (ignore_sigio): New decl.
2232 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
2233 unconditionally, since it's now a no-op if !USABLE_SIGIO.
2234 * emacs.c (shut_down_emacs):
2235 * keyboard.c (kbd_buffer_store_event_hold):
2236 Use ignore_sigio rather than invoking 'signal' directly.
2237 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
2239 (FIONREAD, SIGIO): Do not #undef.
2240 (tty_read_avail_input): Use #error rather than a syntax error.
2241 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
2242 for I_PIPE, used by SETUP_SLAVE_PTY.
2243 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
2244 * sysdep.c (croak): Remove; no longer needed. This bit of
2245 temporary code, with Fred N. Fish's comment that it's temporary,
2246 has been in Emacs since at least 1992!
2247 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
2248 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
2249 * syssignal.h (croak): Remove decl.
2250 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
2251 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
2252 now that we're termios-only.
2253 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
2254 * term.c (dissociate_if_controlling_tty): Use #error rather than
2257 Work around GCC and GNOME bugs when --enable-gcc-warnings.
2258 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
2259 to work around GNOME bug 683906.
2260 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
2261 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
2262 This works around GCC bug 54561.
2264 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
2266 More fixes for 'volatile' and setjmp/longjmp.
2267 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
2268 * image.c (struct png_load_context) [HAVE_PNG]: New type.
2269 (png_load_body) [HAVE_PNG]:
2270 (jpeg_load_body) [HAVE_JPEG]:
2271 New function, with most of the old parent function's body.
2272 (png_load) [HAVE_PNG]:
2273 (jpeg_load) [HAVE_JPEG]:
2274 Invoke the new function, to avoid longjmp munging our locals.
2275 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
2276 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
2277 longjmp is passed 2, as the C standard doesn't guarantee this.
2278 Instead, store the failure code into mgr->failure_code.
2280 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
2282 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
2283 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
2284 (syms_of_keyboard): Remove support for unread-command-char.
2286 2012-09-12 Eli Zaretskii <eliz@gnu.org>
2288 * w32proc.c (sys_kill): If PID is our process ID and the signal is
2289 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
2290 violation. (Bug#12426)
2292 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
2294 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
2296 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
2298 * eval.c: Add `inhibit-debugger'.
2299 (Qinhibit_debugger): New symbol.
2300 (call_debugger): Bind it instead of Qdebug_on_error.
2301 (maybe_call_debugger): Test Vinhibit_debugger.
2302 (syms_of_eval): Define inhibit-debugger.
2303 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
2304 (syms_of_xdisp): Remove inhibit-debug-on-message.
2306 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
2308 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
2309 If a nonvolatile local variable is written before a _longjmp to
2310 the frame containing the variable, and is read after the _longjmp,
2311 the value read is indeterminate. Some local variables of type
2312 'struct handler' and 'struct catchtag' are used in this way, so
2313 mark each of their slots as volatile if the slot can be set before
2314 _longjmp and read afterwards.
2315 * lisp.h (struct handler): var and chosen_clause are now volatile.
2316 (struct catchtag): val, next, and pdlcount are now volatile.
2318 * bidi.c (bidi_push_it, bidi_pop_it):
2319 * fns.c (copy_hash_table):
2320 * image.c (define_image_type):
2321 * keyboard.c (kbd_buffer_store_event_hold):
2322 * process.c (Fprocess_send_eof):
2323 * xfaces.c (x_create_gc) [HAVE_NS]:
2324 * xgselect.c (xg_select):
2325 Prefer assignment to memcpy when either will do.
2327 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
2328 Use pointer-to-a-pointer to simplify and avoid a NILP check each
2329 time an item is removed. No need to mark this function 'inline';
2330 the compiler knows better than we do.
2332 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
2334 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
2335 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
2336 to change_frame_size (Bug#12388).
2337 (windowDidResize:): Pass YES to updateFrameSize.
2339 * nsterm.h: Add delay parameter to updateFrameSize.
2341 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
2343 Discard killed buffers from deleted window and frame objects.
2344 This reduces an amount of references to killed buffers and
2345 helps GC to reclaim them faster.
2346 * alloc.c (discard_killed_buffers): New function.
2347 (mark_object): Use it for deleted windows and frames.
2348 (mark_object): If symbol's value is set up for a killed buffer
2349 or deleted frame, restore its global binding.
2350 * data.c (swap_in_global_binding): Add GC notice.
2351 (swap_in_symval_forwarding): Use convenient set_blv_where.
2352 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
2353 * window.h: ... to here.
2355 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
2357 Convenient macro to check whether the buffer is live.
2358 * buffer.h (BUFFER_LIVE_P): New macro.
2359 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
2360 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
2362 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2364 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
2365 composition cases (Bug#12364).
2367 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
2368 overhang of succeeding glyphs overlapping box cursor.
2370 * w32term.c (x_draw_glyph_string): Likewise.
2372 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
2374 Simplify, document, and port floating-point (Bug#12381).
2375 The porting part of this patch fixes bugs on non-IEEE platforms
2376 with frexp, ldexp, logb.
2377 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
2379 * floatfns.c: Simplify discussion of functions that Emacs doesn't
2380 support, by removing commented-out code and briefly listing the
2381 C89 functions excluded. The commented-out stuff was confusing
2382 maintenance, e.g., we thought we needed cbrt but it was commented out.
2383 (logb): Remove decl; no longer needed.
2384 (isfinite): New macro, if not already supplied.
2385 (isnan): Don't replace any existing macro.
2386 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
2387 are present on all C89 platforms.
2388 (Ffrexp): Do not special-case zero, as frexp does the right thing
2390 (Flogb): Do not use logb, as it doesn't have the desired meaning
2391 on hosts that use non-base-2 floating point. Instead, stick with
2392 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
2393 frexp, to avoid getting an unspecified result.
2395 * xdisp.c (Qinhibit_debug_on_message): Now static.
2397 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
2399 * nsterm.m (ns_update_begin): Set clip path to whole view by using
2400 NSBezierPath (Bug#12131).
2402 2012-09-10 Chong Yidong <cyd@gnu.org>
2404 * fns.c (Fdelq, Fdelete): Doc fix.
2406 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
2408 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
2409 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
2411 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
2413 * lisp.h (make_lisp_ptr): New macro to replace XSET.
2414 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
2417 2012-09-09 Eli Zaretskii <eliz@gnu.org>
2419 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
2420 left fringe if the window has a left margin. This avoids leaving
2421 traces of the cursor because its leftmost pixel is not drawn over.
2423 * dispnew.c (update_window_line): When the left margin area of a
2424 screen line is updated, set the redraw_fringe_bitmaps_p flag of
2425 that screen line. (Bug#12277)
2427 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
2429 Assume C89 or later for math functions (Bug#12381).
2430 This simplifies the code, and makes it a bit smaller and faster,
2431 and (most important) makes it easier to clean up signal handling
2432 since we can stop worring about floating-point exceptions in
2433 library code. That was a problem before C89, but the problem
2434 went away many years ago on all practical Emacs targets.
2435 * data.c, image.c, lread.c, print.c:
2436 Don't include <math.h>; no longer needed.
2437 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
2438 might be autoconfigured, as that never happens.
2440 * doprnt.c (DBL_MAX_10_EXP):
2441 * print.c (DBL_DIG):
2442 Remove. C89 or later always defines these.
2443 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
2444 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
2445 (arith_error, domain_error, domain_error2):
2446 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
2447 no longer needed -- we simply return what C returns. All uses removed.
2448 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
2450 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
2451 Remove. All uses expanded, as these macros are no longer used
2452 more than once and are now more trouble than they're worth.
2453 (Ftan): Use tan, not sin / cos.
2454 (Flogb): Assume C89 frexp.
2455 (fmod_float): Assume C89 fmod.
2456 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
2457 (init_floatfns): Remove. All uses removed.
2459 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
2461 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
2462 compositeToPoint for OSX < 10.6 (Bug#12390).
2464 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
2466 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
2467 This produces more-accurate results.
2469 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
2471 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
2472 changes (Bug#12088).
2474 2012-09-08 Chong Yidong <cyd@gnu.org>
2476 * syntax.c (Fstring_to_syntax): Doc fix.
2478 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
2480 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
2481 in the internal border.
2482 (x_set_window_size): Remove static variables and their usage.
2483 (ns_redraw_scroll_bars): Fix NSTRACE arg.
2484 (ns_after_update_window_line, ns_draw_fringe_bitmap):
2485 Remove fringe/internal border adjustment (Bug#11052).
2486 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
2487 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
2488 (ns_fix_rect_ibw): Remove.
2489 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
2490 (ns_dumpglyphs_box_or_relief): Ditto.
2491 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
2493 (ns_dumpglyphs_image): Ditto.
2494 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
2496 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
2497 their usage. Add fringe_extended_p and its use as in other terms.
2498 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
2499 scroll bar was removed.
2500 (updateFrameSize): New function.
2501 (windowDidResize): Move code to updateFrameSize and call it.
2503 * nsterm.h (EmacsView): Add updateFrameSize.
2505 2012-09-07 Chong Yidong <cyd@gnu.org>
2507 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
2509 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
2511 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
2513 More signal-handler cleanup (Bug#12327).
2514 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
2515 Problem introduced when merging patches. Noted by Eli Zaretskii in
2516 <http://bugs.gnu.org/12327#67>.
2517 * floatfns.c: Comment fix.
2518 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
2519 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
2520 and anyway the declaration is harmless even if SIGDANGER is not defined.
2521 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
2522 defined BROKEN_FIONREAD). systty.h formerly did this, but other
2523 source files not surprisingly expected syssignal.h to define, or
2524 not define, SIGIO, and it's cleaner to do it that way, for consistency.
2525 Include <sys/ioctl.h>, for FIONREAD.
2526 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
2527 This eliminates a problem whereby other files mysteriously had
2528 to include "syssignal.h" before including "systty.h" if they
2529 wanted to use "#ifdef SIGIO".
2531 2012-09-07 Eli Zaretskii <eliz@gnu.org>
2533 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
2535 * w32.c (sigemptyset): Empty the set.
2536 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
2538 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
2540 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
2542 * alloc.c (mark_buffer): Revert unsafe marking optimization.
2543 (mark_object): Likewise for frame objects.
2545 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
2547 * syssignal.h (handle_on_main_thread): Always declare,
2548 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
2549 This ports to platforms without HAVE_PTHREAD.
2551 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
2553 Signal-handler cleanup (Bug#12327).
2554 Emacs's signal handlers were written in the old 4.2BSD style with
2555 sigblock and sigmask and so forth, and this led to some
2556 inefficiencies and confusion. Rewrite these to use
2557 pthread_sigmask etc. without copying signal sets around. Also,
2558 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
2559 'signal', and instead use functions that do not attempt to take
2560 over the system name space. This patch causes Emacs's text
2561 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
2562 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
2563 Do not include <signal.h> or "syssignal.h", as these
2564 modules do not use signals.
2565 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
2566 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
2567 Do not include <signal.h>, as "syssignal.h" does that for us now.
2568 * atimer.c (sigmask_atimers): New function.
2569 (block_atimers, unblock_atimers): New functions,
2570 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
2572 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
2573 no longer needed here.
2574 * emacs.c (main): Inspect existing signal handler with sigaction,
2575 so that there's no need to block and unblock SIGHUP.
2576 * sysdep.c (struct save_signal): New member 'action', replacing
2577 old member 'handler'.
2578 (save_signal_handlers, restore_signal_handlers):
2579 Use sigaction instead of 'signal' to save and restore.
2580 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
2581 New function. All users of 'signal' modified to use set_sighandler
2582 if they're writeonly, and to use sys_signal if they're read+write.
2583 (emacs_sigaction_init, forwarded_signal): New functions.
2584 (sys_signal): Remove. All uses replaced by calls to sigaction
2585 and emacs_sigaction_init, or by direct calls to 'signal'.
2586 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
2587 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
2588 all uses replaced by pthread_sigmask etc. calls.
2589 * syssignal.h: Include <signal.h>.
2590 (emacs_sigaction_init, forwarded_signal): New decls.
2591 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
2592 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
2593 (sigmask, sys_sigmask): Remove; no longer needed.
2594 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
2595 (sigblock, sigunblock, sigfree):
2596 (sigsetmask) [!defined sigsetmask]:
2597 Remove. All uses replaced by pthread_sigmask.
2598 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
2599 no longer need to be replaced, and its typical old uses
2600 are now done via emacs_sigaction_init and sigaction.
2601 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
2602 (sys_sigdel): Remove; unused.
2603 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
2605 2012-09-06 Eli Zaretskii <eliz@gnu.org>
2607 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
2608 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
2610 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
2612 Explicitly mark buffer_defaults and buffer_local_symbols.
2613 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
2614 mark_local_symbols here.
2615 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
2616 since special buffers aren't marked here any more.
2617 (allocate_buffer): Chain new buffer with all_buffers here...
2618 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
2620 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
2621 (syms_of_buffer): Remove staticpro of the above.
2622 (init_buffer_once): Set names for buffer_defaults and
2623 buffer_local_symbols.
2625 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
2627 Use bool for booleans in font-related modules.
2628 * font.c (font_intern_prop, font_style_to_value)
2629 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
2630 (generate_otf_features, font_check_otf_features, font_check_otf)
2631 (font_match_p, font_list_entities, font_at):
2632 * fontset.c (fontset_id_valid_p, reorder_font_vector
2633 (fontset_find_font, Fset_fontset_font)
2634 (face_suitable_for_char_p) [0]:
2635 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
2636 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
2637 (m17n_flt_initialized, ftfont_shape_by_flt):
2638 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
2639 * nsfont.m (nsfont_draw):
2640 * w32font.c (w32font_draw):
2641 * w32term.c (x_draw_glyphless_glyph_string_foreground):
2642 Use bool for booleans.
2643 * font.h: Adjust to above API changes.
2644 (struct font, struct font_driver, struct font_driver_list):
2645 Use bool for booleans.
2646 (struct font): Remove useless member encoding_type.
2648 * fontset.c, xftfont.c: Omit unnecessary static decls.
2650 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
2652 * alloc.c (mark_object): Revert window marking code
2653 since it's unsafe for the Fset_window_configuration.
2655 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
2657 Fix race conditions with signal handlers and errno (Bug#12327).
2658 Be more systematic about preserving errno whenever a signal
2659 handler returns, even if it's not in the main thread. Do this by
2660 renaming signal handlers to distinguish between signal delivery
2661 and signal handling. All uses changed.
2662 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
2663 * data.c (deliver_arith_signal): Rename from arith_error.
2664 * dispnew.c (deliver_window_change_signal): Rename from
2665 window_change_signal.
2666 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
2667 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
2668 * keyboard.c (deliver_input_available_signal): Rename from
2669 input_available_signal.
2670 (deliver_user_signal): Rename from handle_user_signal.
2671 (deliver_interrupt_signal): Rename from interrupt_signal.
2672 * process.c (deliver_pipe_signal): Rename from send_process_trap.
2673 (deliver_child_signal): Rename from sigchld_handler.
2674 * atimer.c (handle_alarm_signal):
2675 * data.c (handle_arith_signal):
2676 * dispnew.c (handle_window_change_signal):
2677 * emacs.c (handle_fatal_signal, handle_danger_signal):
2678 * keyboard.c (handle_input_available_signal):
2679 * keyboard.c (handle_user_signal, handle_interrupt_signal):
2680 * process.c (handle_pipe_signal, handle_child_signal):
2681 New functions, with the actual signal-handling code taken from the
2682 original respective signal handlers, sans the sporadic attempts to
2683 preserve errno, since that's now done by handle_on_main_thread.
2684 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
2685 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
2686 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
2688 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
2689 Move initialization of main_thread to sysdep.c's init_signals.
2690 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
2691 our usage, and simplifies the mainline code.
2692 (record_child_status_change): New static function, as a helper
2693 for handle_child_signal, and with most of the old child handler's
2695 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
2696 (handle_child_signal): Use the above.
2697 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
2698 Moved here from emacs.c.
2699 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
2700 code moved here from emacs.c's main function.
2701 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
2702 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
2703 This lets callers save and restore errno properly.
2705 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
2707 Remove redundant or unused things here and there.
2708 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
2709 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
2710 * editfns.c (Fcompare_buffer_substrings): Likewise.
2711 * frame.h (struct terminal, struct font_driver_list):
2712 Remove redundant declarations.
2713 * window.h (Qleft, Qright): Likewise.
2715 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
2717 Do not mark objects from deleted buffers, windows and frames.
2718 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
2719 (mark_object): Likewise for windows and frames.
2721 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
2723 * alloc.c (valid_lisp_object_p): Treat killed buffers,
2724 buffer_defaults and buffer_local_symbols as valid objects.
2725 Return special value to denote them.
2727 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
2729 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
2730 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
2731 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
2732 (file_name_absolute_p, Fsubstitute_in_file_name):
2733 (check_executable, check_writable, Ffile_accessible_directory_p)
2734 (Fset_file_selinux_context, Fdefault_file_modes)
2735 (Finsert_file_contents, choose_write_coding_system)
2736 (Fwrite_region, build_annotations, a_write, e_write)
2738 * filelock.c (boot_time_initialized, get_boot_time)
2739 (get_boot_time_1, lock_file_1, within_one_second):
2740 * floatfns.c (in_float):
2741 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
2742 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
2743 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
2744 * lisp.h (struct Lisp_Hash_Table.cmpfn):
2745 * window.c (compare_window_configurations):
2746 Use bool for booleans.
2747 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
2748 (Fdefault_file_modes): Now mode_t, not int, for modes.
2749 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
2750 (internal_delete_file): Now returns void, not a (boolean) int,
2751 since nobody was looking at the return value.
2752 * lisp.h, window.h: Adjust to above API changes.
2754 * xdisp.c (set_message): Simplify and reindent last change.
2756 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
2758 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
2760 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
2762 * eval.c (call_debugger): Make the function non-static so that we
2763 can call it from set_message.
2765 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
2766 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
2768 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
2770 Give more-useful info on a fatal error (Bug#12328).
2771 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
2772 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
2773 of doing the work ourselves.
2774 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
2775 do most of the work.
2776 (fatal_error_backtrace): New function, taken from the guts
2777 of the old fatal_error_signal, but with a new option to output
2779 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
2780 info about the signal than just its number.
2781 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
2782 * sysdep.c: Include <execinfo.h>
2783 (emacs_backtrace): New function, taken partly from the previous
2784 code of the 'die' function.
2785 (emacs_abort): Call fatal_error_backtrace rather than abort.
2787 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
2789 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
2790 eager (load-time) macro-expansion.
2791 * lisp.mk (lisp): Add macroexp.
2793 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
2795 Simplify redefinition of 'abort' (Bug#12316).
2796 Do not try to redefine the 'abort' function. Instead, redo
2797 the code so that it calls 'emacs_abort' rather than 'abort'.
2798 This removes the need for the NO_ABORT configure-time macro
2799 and makes it easier to change the abort code to do a backtrace.
2800 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
2801 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
2802 Remove; sysdep.c's emacs_abort now takes its place.
2803 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
2804 'abort' changed to use 'emacs_abort'.
2805 * msdos.c (dos_abort) [defined abort]: Remove; not used.
2806 (abort) [!defined abort]: Rename to ...
2807 (emacs_abort): ... new name.
2808 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
2809 the place of the old 'abort' in emacs.c.
2810 * w32.c, w32fns.c (abort): Do not #undef.
2811 * w32.c (emacs_abort): Rename from w32_abort.
2813 2012-09-04 Eli Zaretskii <eliz@gnu.org>
2815 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
2816 offsets[j].dv, since the y axis of the screen coordinates points
2817 down, while the y axis of the font definition coordinates points
2818 up. This fixes display of Arabic diacritics such as KASRA and
2819 KASRATAN. (Bug#11860)
2821 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
2823 Be more systematic about _setjmp vs setjmp.
2824 * alloc.c (test_setjmp, mark_stack):
2825 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
2826 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
2827 (png_load, my_error_exit, jpeg_load):
2828 * process.c (send_process_trap, send_process):
2829 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
2830 The underscored versions are up to 30x faster on some hosts.
2831 Formerly, the code used setjmp+longjmp sometimes and
2832 _setjmp+_longjmp at other times, with no particular reason to
2833 prefer setjmp+longjmp.
2835 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
2837 Fix minor problem found by static checking.
2838 * buffer.c (Fdelete_all_overlays): Return nil.
2840 2012-09-03 Martin Rudalics <rudalics@gmx.at>
2842 * buffer.c (Fdelete_all_overlays): New function.
2844 2012-09-03 Chong Yidong <cyd@gnu.org>
2846 * gtkutil.c: Add extern decl for Qxft.
2848 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>

2863 * eval.c (interactive_p): Omit always-true boolean argument
2864 EXCLUDE_SUBRS_P. All callers changed.
2865 * dispextern.h, lisp.h: Reflect above API changes.
2866 * firstfile.c (dummy): Use the address of 'main', whose signature
2867 won't change, instead of the address of 'initialize', whose
2868 signature just changed from int to bool.
2869 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
2870 * msdos.c (fatal_error_in_progress): ... from here.
2871 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
2873 (redisplay_internal, unwind_redisplay): Simply clear
2874 REDISPLAYING_P when unwinding, instead of saving its previous,
2875 always-false value and then restoring it.
2877 Clean up some extern decls.
2878 Mostly, this hoists extern decls out of .c files and into .h files.
2879 That way, we're more likely to catch errors if the interfaces change.
2880 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
2881 declare xg_mark_data.
2882 * dispextern.h (x_frame_parm_handlers):
2884 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)

2898 * widget.c (free_frame_faces):
2899 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
2900 * xfont.c (x_clear_errors):
2901 * xterm.c (x_frame_parm_handlers):
2902 Remove now-redundant extern decls.
2903 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
2904 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
2906 * xfaces.c: Remove unnecessary static decls.
2907 * xterm.c (updating_frame): Remove decl of nonexistent object.
2909 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
2910 when building globals.h, as the objects that are not built on
2911 this host are not needed to compile C files on this host.
2913 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
2915 * gtkutil.h: Remove prototype for x_wm_set_size_hint.

2929 (make_buffer_string, make_buffer_string_both)
2930 (Fsubst_char_in_region, Ftranslate_region_internal, Fformat):

2942 (set_intervals_multibyte_1, set_intervals_multibyte):
2943 * keyboard.c (decode_timer):
2944 Use bool for boolean.
2945 * intervals.h, lisp.h, systime.h: Reflect above API changes.

2953 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
2955 * makefile.w32-in (CCL_H, W32FONT_H): New macros.
2956 (ATIMER_H, FONT_H, $(BLD)/alloc.$(O), $(BLD)/callproc.$(O))

2963 2012-09-01 Eli Zaretskii <eliz@gnu.org>
2965 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
2966 more than one grapheme cluster passed to the shaper: compute the
2967 offset adjustment values separately for each cluster. (Bug#11860)
2969 * image.c: Restore mistakenly removed inclusion of w32.h. Without
2970 it, GCC doesn't see prototypes of w32_delayed_load, and complains
2971 about implicit conversions from integer to pointer.
2973 2012-09-01 Daniel Colascione <dancol@dancol.org>
2975 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
2976 system used too early.
2978 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
2980 Better seed support for (random).

3022 window-system headers.

3025 window-system headers. Declare Vlibrary_cache when compiling for
3028 * gtkutil.h (xg_list_node_): Include xterm.h to pick up needed
3029 window system declarations.
3031 * frame.h: Move common functions here: set_frame_menubar,
3032 x_set_window_size, x_sync, x_get_focus_frame,
3033 x_set_mouse_position, x_set_mouse_pixel_position,
3034 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

3058 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
3060 Remove mark_ttys function and fix tty_display_info initialization.
3061 * lisp.h (mark_ttys): Remove prototype.
3062 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
3063 to mark_ttys because all possible values of 'top_frame' slot are
3064 the frames which are reachable from Vframe_list.
3065 * term.c (mark_ttys): Remove.
3066 (init_tty): Safely initialize 'top_frame' slot with Qnil.
3068 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>

3074 'window_sizes_changed', 'mouse_moved' and 'pointer_invisible'
3075 bitfields from unsigned char to unsigned.

3090 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
3091 for GCC 4.7.1 x86-64.
3093 2012-08-30 Glenn Morris <rgm@gnu.org>
3095 * lread.c (init_lread): For out-of-tree builds, only add the
3096 source directory's site-lisp dir to the load-path if it exists,
3097 consistent with in-tree builds. (Bug#12302)
3099 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>
3101 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize

3111 (addSplit): Remove return self, declare return value as void.
3112 (clicked:): Remove return self, declare return value as void.
3113 Set dialog_return to button_values[seltag]. Code formatting change.

3116 (timeout_handler:): Set timer_fired to YES.
3117 (runDialogAt:): Set timer_fired to NO.
3118 Handle click on close button as quit.
3120 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
3121 Add window_closed and button_values. Add void as return value for
3122 add(Button|String|Split). addButton takes int instead of Lisp_Object.
3123 Add process_dialog as new member.
3125 2012-08-28 Eli Zaretskii <eliz@gnu.org>
3127 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it

3211 (windowShouldClose:): Use stop instead of stopModalWithCode.
3212 (clicked:): Ditto, and also set dialog_return (Bug#12258).
3213 (timeout_handler:): Use stop instead of abortModal. Send a dummy
3215 (runDialogAt:): Make ret Lisp_Object. Set it from dialog_return when
3218 2012-08-27 Paul Eggert <eggert@cs.ucla.edu>
3220 * composite.c, data.c, dbusbind.c, dired.c: Use bool for booleans.
3221 * composite.c (find_composition, composition_gstring_p)
3222 (composition_reseat_it, find_automatic_composition):
3223 * data.c (let_shadows_buffer_binding_p)
3224 (let_shadows_global_binding_p, set_internal, make_blv)

3226 (Fmake_variable_frame_local, arithcompare, cons_to_unsigned)
3227 (cons_to_signed, arith_driver):
3228 * dbusbind.c (xd_in_read_queued_messages):
3229 * dired.c (directory_files_internal, file_name_completion):
3230 Use bool for booleans.
3231 * dired.c (file_name_completion):
3232 * process.h (fd_callback):
3233 Omit int (actually boolean) argument. It wasn't being used.
3235 * composite.h, lisp.h: Reflect above API changes.
3237 * cmds.c, coding.c: Use bool for booleans.
3238 * cmds.c (move_point, Fself_insert_command):
3239 * coding.h (struct composition status, struct coding_system):
3240 * coding.c (detect_coding_utf_8, encode_coding_utf_8)

3257 (code_convert_string, code_convert_string_norecord)
3258 (Fset_coding_system_priority):
3259 * fileio.c (Finsert_file_contents):
3260 Use bool for booleans.
3261 * coding.h, lisp.h: Reflect above API changes.
3262 * coding.c: Remove unnecessary static function decls.
3263 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
3264 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
3265 not a boolean 'int', since callers never look at the return value.
3266 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
3267 * coding.h (decoding_buffer_size, encoding_buffer_size)
3268 (emacs_mule_string_char): Remove unused extern decls.
3269 (struct iso_2022_spec, struct coding_system):
3270 Use 'unsigned int : 1' for boolean fields, since there's more than one.
3271 (struct emacs_mule_spec): Remove unused field 'full_support'.
3272 All initializations removed.
3273 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
3275 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
3277 Fix spare memory change (Bug#12286).
3278 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
3279 (valid_lisp_object_p): Likewise.
3281 2012-08-27 Martin Rudalics <rudalics@gmx.at>
3283 * window.c (Fset_window_configuration): Record any window's old
3284 buffer if it's replaced (see Bug#8789). If the new current
3285 buffer doesn't appear in the selected window, go to its old
3288 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
3290 Special MEM_TYPE_SPARE to denote reserved memory.
3291 * alloc.c (enum mem_type): New memory type.
3292 (refill_memory_reserve): Use new type for spare memory.
3293 This prevents live_cons_p and live_string_p from incorrect
3294 detection of uninitialized objects from spare memory as live.
3296 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
3299 * Makefile.in (.PHONY): versioclean -> versionclean.
3301 Remove unused external symbols.
3302 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
3303 * window.c (Qwindow_valid_p, decode_valid_window):
3304 Now static, not extern.
3305 * data.c (Qinterval): Remove; unused.
3306 (syms_of_data): Do not define 'interval'.
3307 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
3308 * window.h (decode_valid_window):
3311 * character.c, charset.c, chartab.c: Use bool for booleans.
3312 * character.c (lisp_string_width, string_count_byte8)
3313 (string_escape_byte8):
3314 * charset.c (charset_map_loaded, load_charset_map, read_hex):
3315 (load_charset_map_from_file, map_charset_chars)
3316 (Fdefine_charset_internal, define_charset_internal)
3317 (Fdeclare_equiv_charset, find_charsets_in_text)
3318 (Ffind_charset_region, char_charset, Fiso_charset):
3319 * chartab.c (sub_char_table_ref, sub_char_table_ref_and_range)
3320 (sub_char_table_set, sub_char_table_set_range)
3321 (char_table_set_range, optimize_sub_char_table)
3322 (map_sub_char_table):
3323 Use bool for boolean.
3324 * character.c (str_to_unibyte): Omit last boolean argument; it was
3325 always 0. All callers changed.
3326 * character.h, charset.h: Adjust to match previous changes.
3327 * character.h (char_printable_p): Remove decl of nonexistent function.
3328 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
3329 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
3330 are all boolean, so make them single-bit bitfields.
3332 * lisp.h (ASET): Remove attempt to detect side effects.
3333 It was meant to be temporary and it often doesn't work,
3334 because when IDX has side effects the behavior of IDX==IDX
3335 is undefined. See Stefan Monnier in
3336 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
3338 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
3340 * lisp.h (functionp): New function (extracted from Ffunctionp).
3341 (FUNCTIONP): Use it.
3342 * eval.c (Ffunctionp): Use it.
3344 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
3346 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
3347 as that's faster and simpler than static storage. Don't bother
3348 with the g_main_context_query overhead if g_main_context_pending
3349 says no events are pending.
3350 (gfds, gfds_size): Remove these static vars.
3351 (xgselect_initialize): Remove; no longer needed.
3352 All uses and decls removed.
3354 * emacs.c (fatal_error_signal_hook): Remove.
3355 All uses removed. This leftover from old code was always 0.
3357 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
3358 * casefiddle.c (casify_object, casify_region):
3359 * casetab.c (set_case_table):
3360 * category.c, category.h (word_boundary_p):
3361 * category.h (CHAR_HAS_CATEGORY):
3362 Use bool for booleans, instead of int.
3364 2012-08-25 Eli Zaretskii <eliz@gnu.org>
3366 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
3368 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
3370 On assertion failure, print backtrace if available.
3371 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
3372 (die) [ENABLE_CHECKING]: Print a backtrace if available.
3373 * Makefile.in (LIB_EXECINFO): New macro.
3376 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
3377 * bytecode.c (exec_byte_code):
3378 * callint.c (check_mark, Fcall_interactively):
3379 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
3380 (getenv_internal, sync_process_alive, call_process_exited):
3381 * lisp.h (USE_SAFE_ALLOCA):
3382 Use bool for booleans, instead of int.
3383 * lisp.h, process.h: Adjust prototypes to match above changes.
3384 * callint.c (Fcall_interactively): Don't assume the mark's
3385 offset fits in 'int'.
3387 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
3389 * buffer.c, buffer.h: Use bool for boolean.
3390 * buffer.c (reset_buffer_local_variables)
3391 (buffer_lisp_local_variables, Fset_buffer_modified_p)
3392 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
3393 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
3394 (overlay_touches_p, overlay_strings, Foverlay_put)
3395 (report_overlay_modification, call_overlay_mod_hooks):
3396 (mmap_enlarge, mmap_set_vars):
3397 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
3398 Use bool for booleans, instead of int.
3399 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
3400 since the 1-or-0 return value is always ignored anyway.
3401 (mmap_initialized_p):
3402 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
3403 * buffer.h, lisp.h: Adjust prototypes to match above changes.
3405 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
3407 * bidi.c: Use bool for boolean.
3408 This is a bit more readable, and makes the text segment of bidi.o
3409 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
3410 Presumably it's faster too.
3411 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
3413 (bidi_cache_find_level_change, bidi_cache_iterator_state)
3414 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
3415 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
3416 (bidi_explicit_dir_char, bidi_level_of_next_char)
3417 (bidi_find_other_level_edge, bidi_move_to_visually_next):
3418 Use bool for booleans, instead of int.
3419 * dispextern.h (bidi_init_it, bidi_paragraph_init)
3420 (bidi_unshelve_cache): Adjust decls to match code.
3422 2012-08-23 Martin Rudalics <rudalics@gmx.at>
3424 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
3427 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
3429 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
3430 * atimer.h: Include <stdbool.h>.
3432 2012-08-22 Dan Nicolaescu <dann@gnu.org>
3434 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
3435 compile time tests instead of run time tests on systems that do
3437 (FRAME_MAC_P): Remove leftover from deleted code.
3438 * frame.c (syms_of_frame): Remove leftover from deleted code.
3440 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
3442 * nsterm.m (insertText:): Don't clear modifiers if code is space.
3444 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
3446 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
3447 Otherwise, the compiler complains about (A?B:C) where B is void
3448 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
3449 (fontset_add): Return void, for FONTSET_ADD.
3451 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
3453 * alloc.c: Use bool for booleans.
3454 (gc_in_progress, abort_on_gc)
3455 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
3456 (dont_register_blocks) [GC_MALLOC_CHECK]:
3457 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
3458 (check_string_bytes, make_specified_string, memory_full)
3459 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
3460 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
3461 (mark_stack, valid_pointer_p, make_pure_string)
3462 (Fgarbage_collect, survives_gc_p, gc_sweep):
3463 Use bool for booleans, instead of int.
3464 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
3465 Remove unused local.
3466 * alloc.c (PURE_POINTER_P):
3467 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
3468 * editfns.c (Fformat):
3469 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
3471 * fns.c (sweep_weak_table):
3472 * lisp.h (suppress_checking, push_message, survives_gc_p)
3473 (make_pure_string, gc_in_progress, abort_on_gc):
3474 * lread.c (readchar, read1):
3475 * print.c (Fprin1_to_string):
3476 * xdisp.c (push_message):
3477 Use bool for booleans affected directly or indirectly by
3480 Make recently-introduced setters macros.
3481 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
3482 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
3483 (set_fontset_default, set_fontset_fallback): Rename from their
3484 upper-case counterparts, and make them functions rather than macros.
3485 This is more consistent with the other recently-introduced setters.
3486 These don't need to be inline, since they're local.
3488 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
3490 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
3491 the loop (Bug#12247).
3493 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
3495 * lisp.h (vcopy): Use memcpy rather than our own loop.
3496 This fixes a performance regression introduced by the recent
3497 addition of vcopy. This means 'vcopy' will need to be modified
3498 for a copying collector, but that's OK. Also, tighten the
3499 checking in the assertion.
3501 2012-08-21 Eli Zaretskii <eliz@gnu.org>
3503 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
3504 components for RTL text (Bug#11860). Adjust X-OFFSET of each
3505 non-base glyph for the width of the base character, according to
3506 what x_draw_composite_glyph_string_foreground expects.
3507 Generate WADJUST value according to composition_gstring_width's
3508 expectations, to produce correct width of the composed character.
3509 Reverse the sign of the DU offset produced by ScriptPlace.
3511 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
3513 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
3515 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
3517 Avoid direct writes to contents member of struct Lisp_Vector.
3518 * lisp.h (vcopy): New function to copy data into vector.
3519 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
3520 * fns.c (Ffillarray): Use ASET.
3521 * keyboard.c (timer_check_2): Use AREF and ASET.
3522 (append_tool_bar_item, Frecent_keys): Use vcopy.
3523 * lread.c (read_vector): Use ASET.
3524 * msdos.c (Frecent_doskeys): Use vcopy.
3525 * xface.c (Finternal_copy_lisp_face): Use vcopy.
3526 (Finternal_merge_in_global_face): Use ASET and vcopy.
3527 * xfont.c (xfont_list_pattern): Likewise.
3529 2012-08-21 Martin Rudalics <rudalics@gmx.at>
3531 * window.c (Fwindow_point): For the selected window always return
3532 the position of its buffer's point.
3533 (Fset_window_point): For the selected window always go in its
3534 buffer to the specified position.
3536 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
3538 Setter macros for fontsets.
3539 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
3540 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
3541 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
3544 2012-08-20 Glenn Morris <rgm@gnu.org>
3546 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
3547 Don't assume that `ln -f' works.
3549 2012-08-20 Eli Zaretskii <eliz@gnu.org>
3551 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
3552 and later about non-assignments with no effect. See discussion at
3553 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
3556 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
3558 Inline setter functions for Lisp_Objects slots of struct specbinding.
3559 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
3562 2012-08-20 Martin Rudalics <rudalics@gmx.at>
3564 * window.c (select_window): Always make selected window's buffer
3567 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
3569 Use AREF and ASET for docstrings of category tables.
3570 * category.h (CATEGORY_DOCSTRING): Use AREF.
3571 (SET_CATEGORY_DOCSTRING): Use ASET.
3572 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
3574 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
3576 Inline setter functions for hash table members.
3577 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
3578 (set_hash_hash, set_hash_index): Rename with _slot suffix.
3579 (set_hash_key_and_value, set_hash_index, set_hash_next)
3580 (set_hash_hash): New functions.
3581 * charset.c, fns.c: Adjust users.
3583 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
3585 Inline getter and setter functions for per-buffer values.
3586 * buffer.h (per_buffer_default, set_per_buffer_default)
3587 (per_buffer_value, set_per_buffer_value): New functions.
3588 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
3589 * buffer.c, data.c: Adjust users.
3591 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
3593 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
3595 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
3597 Rely on <config.h> + <unistd.h> to declare 'environ',
3598 as gnulib does this if the system doesn't.
3599 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
3600 Remove declaration. MS-Windows declares it on stdlib.h which is
3601 included by conf_post.h.
3602 * emacs.c (environ) [DOUG_LEA_MALLOC]:
3603 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
3604 * vm-limit.c: Include <unistd.h>, for 'environ'.
3606 * unexaix.c, unexcoff.c: Include "mem-limits.h".
3607 (start_of_data): Remove decl; mem-limits.h provides it.
3609 * xdisp.c (handle_invisible_prop): Make it a bit faster
3610 and avoid a gcc -Wmaybe-uninitialized diagnostic.
3612 2012-08-19 Chong Yidong <cyd@gnu.org>
3614 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
3617 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
3619 * .gdbinit: Use call instead of set when calling a function in the
3622 * data.c (set_internal): Don't use set_blv_found.
3623 (Fkill_local_variable): Likewise.
3625 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
3627 * nsfont.m (ns_ascii_average_width): Ensure the string
3628 ascii_printable is initialized with a null-terminated character
3629 array. Otherwise, it can contain undesired extra characters.
3631 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
3633 port new setting code to Sun C 5.8 2005/10/13
3634 * chartab.c, lisp.h (char_table_set, char_table_set_range):
3635 Return void, not Lisp_Object. Otherwise, the compiler
3636 complains about (A?B:C) where B is void and C is Lisp_Object
3637 when compiling CHAR_TABLE_SET, due to the recent change to
3638 the API of sub_char_table_set_contents.
3640 2012-08-18 Chong Yidong <cyd@gnu.org>
3642 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
3643 for the string case (Bug#3874).
3645 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
3647 * buffer.h (BSET): Remove (Bug#12215).
3648 Replace all uses with calls to new setter functions.

4527 * alloc.c (record_xmalloc): New function.
4528 * lisp.h (record_xmalloc): New decl.
4529 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
4530 more like a function. This is because the pointer cast is not
4531 needed. All uses changed.
4532 * print.c (print_string, print_error_message): Avoid length recalc.
4534 Improve fix for macroexp crash with debugging (Bug#12118).
4535 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
4536 ARRAY_MARK_FLAG when checking subscripts, because ASET is
4537 not supposed to be invoked from the garbage collector.
4538 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
4539 (gc_aset): New function, which is like ASET but can be
4540 used in the garbage collector.

4569 with addition of handling of symlinks and support for 'lstat'.
4570 If possible, get file's attributes and security information by
4571 handle, not by name. Produce S_IFLNK bit for symlinks, when
4572 called from 'lstat'.
4573 (stat, lstat): New functions, call 'stat_worker'.
4574 (symlink, readlink, careadlinkat): Rewritten to create and resolve
4575 symlinks when the underlying filesystem supports them.
4577 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
4579 Fix macroexp crash on Windows with debugging (Bug#12118).
4580 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
4581 checking subscripts; problem introduced with the recent
4582 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
4583 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
4584 since it's used in non-static inline functions now.
4586 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
4587 Don't assume buffer size fits in 'int'. Remove unused local.

4601 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
4602 * alloc.c (LISP_INLINE):

4605 * character.c (CHARACTER_INLINE):
4606 * charset.c (CHARSET_INLINE):
4607 * composite.c (COMPOSITE_INLINE):
4608 * dispnew.c (DISPEXTERN_INLINE):
4609 * sysdep.c (SYSTIME_INLINE):
4610 Define to EXTERN_INLINE, so that the corresponding functions
4611 are compiled into code.

4613 (INLINE_HEADER_END): New macros.
4614 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

4636 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
4638 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
4639 This how ASET and AREF are supposed to work, and makes
4640 it easier to think about future improvements. See
4641 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
4642 * charset.h (set_charset_attr): New function.

5057 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
5058 enumeration constants, as PURE and HEAP are too general, and clash
5059 with other headers and sources, such as gmalloc.c and the
5060 MS-Windows system headers. All users changed.
5062 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
5064 Revert last save_excursion_save and save_excursion_restore changes.
5065 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

5078 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
5079 arms of an 'if', not using conditional expressions; otherwise GDB
5080 complains about the types in the unevaluated arm when the argument
5081 is an integer literal.
5082 (xgetint): Simplify expression.
5083 * alloc.c (gdb_make_enums_visible): New constant. This ports to
5084 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
5085 Zaretskii in <http://bugs.gnu.org/12036#13>.
5086 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
5087 needed now that we have gdb_make_enums_visible.
5088 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
5089 (enum enum_USE_LSB_TAG):
5090 New enum types, packaging up enums that need to be exported to GDB.

5132 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
5133 emacs.c, as this is a more-suitable home. Had this been done earlier
5134 the fix for 12036 would have avoided some of the problems noted in
5135 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
5136 would have been more obvious.
5137 * emacs.c: Do not include <verify.h>; no longer needed.
5138 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
5139 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
5140 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):

5146 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
5147 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
5148 not be usable in #if. This simplifies things.
5150 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
5152 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.

5157 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
5158 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
5159 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
5160 Adjust to changes in lisp.h and emacs.c, by using
5161 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
5162 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
5163 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
5164 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
5165 instead of gdb_valbits.
5166 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
5167 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
5168 instead of gdb_array_mark_flag.
5169 (xboolvector): Get size from $->size, not $->header.size.
5170 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
5171 (xreload, hook-run, hookpost-run): Remove.
5172 * emacs.c: Include <verify.h>.
5173 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
5174 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
5176 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
5177 (gdb_USE_LSB_TAG): New enum constants.
5178 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
5179 Also define these as enum constants, so they're visible to GDB.
5180 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
5181 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
5182 as constants, so they're visible to GDB.

5185 Now enum constants, not macros, so they're visible to GDB.
5186 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
5187 more convenient now. All uses changed.
5188 (VALMASK) [USE_LSB_TAG]: Also define in this case.
5189 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
5191 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

5198 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
5199 add argument, tune behavior, and adjust all callers.
5201 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
5203 Use typedef for EMACS_INT, EMACS_UINT.
5204 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
5205 than macros. This simplifies debugging in the usual case, since
5206 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
5207 and it allows expressions involving EMACS_INT casts.
5208 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
5210 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

5220 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
5222 Adjust buffer text indirection counters at the end of Fkill_buffer.
5223 * buffer.c (Fkill_buffer): Adjust indirection counters when the
5224 buffer is definitely dead. This should really fix an issue reported
5225 by Christoph Scholtes again. (Bug#12007).
5226 (init_buffer_once): Initialize indirection counters of
5227 buffer_defaults and buffer_local_symbols (for sanity and safety).
5229 2012-07-24 Eli Zaretskii <eliz@gnu.org>
5231 * xdisp.c (init_iterator): Don't compute dimensions of truncation
5232 and continuation glyphs on tooltip frames, leave them at zero.

5260 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
5262 Swap buffer text indirection counters in Fbuffer_swap_text.
5263 * buffer.c (Fbuffer_swap_text): Swap indirections too.
5264 This avoids crash reported by Christoph Scholtes at
5265 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
5267 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
5269 * nsmenu.m (Popdown_data): New struct.
5270 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
5272 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
5273 (initWithContentRect): Make imgView and contentView non-static
5274 and autorelease them. Also autorelease img and matrix (Bug#12005).
5275 (dealloc): Remove (Bug#12005).
5277 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
5279 Adjust consing_since_gc when objects are explicitly freed.

5292 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
5294 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
5295 as it's limited by the amount of memory, not by INT_MAX.
5297 2012-07-21 Eli Zaretskii <eliz@gnu.org>
5299 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
5300 in special-event-map. See the discussion at

5359 * font.c (font_open_by_name): Change 2nd and 3rd args to the only arg
5360 of type Lisp_Object to avoid redundant calls to make_unibyte_string.
5361 Adjust users accordingly.
5362 * font.h (font_open_by_name): Adjust prototype.

5381 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
5382 'for_each_per_buffer_object_at'.
5383 All uses changed. It's better to use upper-case for macros that

5385 that they're special.
5387 2012-07-19 Stefan Monnier <monnier@iro.umontreal.ca>
5389 * alloc.c (Fgarbage_collect): Tweak docstring.

6023 * s/aix4-2.h (unix): Remove; no longer needed.
6025 EMACS_TIME simplification (Bug#11875).
6026 This replaces macros (which typically do not work in GDB)
6027 with functions, typedefs and enums, making the code easier to debug.
6028 The functional style also makes code easier to read and maintain.
6029 * systime.h: Include <sys/time.h> on all hosts, not just if
6030 WINDOWSNT, since 'struct timeval' is needed in general.

6043 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
6044 not functions. All uses rewritten to use the following, respectively:
6045 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
6046 (add_emacs_time, sub_emacs_time): New functions.
6047 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
6048 * fileio.c (Fcopy_file):
6049 * xterm.c (XTflash): Get the current time closer to when it's used.
6050 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

6064 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
6065 (menu_separator_name_p):
6066 * nsmenu.m (ns_update_menubar):
6067 Prefer memcmp to strncmp when either will do.
6068 * nsterm.m: Include <ftoastr.h>.
6070 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
6071 Prefer snprintf to strncpy.
6072 * nsterm.m (ns_term_init):
6073 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
6074 * nsterm.m (ns_term_init):
6075 Avoid the need for strncpy, by using build_string or
6076 make_unibyte_string directly. Use dtoastr, not snprintf.
6077 * process.c (Fmake_network_process): Diagnose service names that
6078 are too long, rather than silently truncating them or creating
6079 non-null-terminated names.
6080 (Fnetwork_interface_info): Likewise, for interface names.
6081 * sysdep.c (system_process_attributes) [GNU_LINUX]:

6086 2012-07-10 Glenn Morris <rgm@gnu.org>
6088 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
6089 Clarify fallback case.
6091 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>

6095 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
6096 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
6097 where argument type is known to be a Lisp_Cons.

6109 Optimize pure C strings initialization.
6110 * lisp.h (make_pure_string): Fix prototype.
6111 (build_pure_c_string): New function, defined as static inline. This
6112 provides a better opportunity to optimize away calls to strlen when
6113 the function is called with compile-time constant argument.
6114 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
6115 argument, adjust users accordingly. Use build_pure_c_string where

6118 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
6119 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
6121 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
6123 Avoid calls to strlen in miscellaneous functions.
6124 * buffer.c (init_buffer): Use precalculated len, adjust if needed.

6130 Avoid calls to strlen in path processing functions.
6131 * fileio.c (file_name_as_directory): Add comment. Change to add
6132 srclen argument and return the length of result. Adjust users

6148 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
6149 We include usg5-4-common.h, which defines them both.
6151 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
6152 O_RDONLY already includes it).
6154 Stop ns builds setting the EMACSLOADPATH environment variable.
6155 * nsterm.m (ns_load_path): Rename from ns_init_paths.
6156 Now it does not set EMACSLOADPATH, just returns the load-path string.
6157 * nsterm.h: Update accordingly.
6158 * lread.c [HAVE_NS]: Include nsterm.h.
6159 (init_lread) [HAVE_NS]: Use ns_load_path.

6162 2012-07-09 Glenn Morris <rgm@gnu.org>
6164 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
6165 since the included bsd-common.h does so.
6167 Stop ns builds setting the EMACSPATH environment variable.
6168 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
6169 (ns_init_paths): Do not set EMACSPATH.
6170 * nsterm.h (ns_exec_path): Add it.
6171 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
6174 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
6176 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
6178 * process.c (wait_reading_process_output): 'waitchannels' was unset
6179 when read_kbd || !NILP (wait_for_cell); fix this.
6181 Add GCC-style 'const' attribute to functions that can use it.
6182 * character.h (char_resolve_modifier_mask):
6183 * keyboard.h (make_ctrl_char):
6184 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)

6195 Minor improvements to make_formatted_string.
6196 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t

6229 Move marker debugging code under MARKER_DEBUG.
6230 * marker.c (MARKER_DEBUG): Move marker debugging code under
6231 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
6232 for bootstrap with --enable-checking (~3x slowdown reported
6233 by Juanma Barranquero <lekktu@gmail.com>).
6234 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
6236 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
6238 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.

6243 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
6244 has no font, use the frame's font. (Bug#11813)
6245 (display_line): Add commentary about displaying truncation glyphs
6247 (produce_special_glyphs): Move here from term.c.
6249 * term.c (produce_special_glyphs): Move to xdisp.c.
6251 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
6254 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
6256 * xdisp.c (display_line): Avoid warning about implicit declaration
6259 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
6261 * lisp.h: Remove empty conditional.
6263 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
6265 * lread.c (load_path_check): Now static.
6267 Fix some minor --with-ns problems found by static checking.
6268 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
6269 (x_set_font) [!HAVE_X_WINDOWS]:
6270 * image.c (xpm_load_image) [HAVE_NS]:
6271 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
6272 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
6273 Remove unused local.
6274 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
6275 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.

6286 * lread.c (load_path_check): New function, split from init_lread.
6287 (init_lread): Reorganize. Motivation:
6288 If EMACSLOADPATH is set, check/warn about that rather than the
6289 defaults, which we are not going to use. Hence we can remove
6290 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
6291 Don't warn if site-lisp directories are missing.
6292 If not installed, start from a blank load-path, since
6293 PATH_LOADSEARCH refers to the eventual installation directories.
6295 2012-07-07 Eli Zaretskii <eliz@gnu.org>
6297 Support truncation and continuation glyphs on GUI frames, when
6298 fringes are disabled. (Bug#11832)

6300 continuation glyphs even if on GUI frames.
6301 Adjust it->last_visible_x on GUI frames when the left or right fringes,
6302 or both, are absent.
6303 (start_display, move_it_in_display_line_to): Handle the case of a
6304 GUI frame without a fringe to display continuation or truncation
6306 (insert_left_trunc_glyphs): Support GUI frames: make sure
6307 truncation glyphs overwrite enough glyphs from the current line to
6308 have sufficient space in pixels.
6309 (display_line): Support truncation and continuation glyphs on GUI
6310 frames. If some spare pixels are left on the line after inserting
6311 the truncation glyphs, fill that space with a stretch glyph of a
6312 suitably computed width.
6314 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
6315 produce_glyphs, to support GUI sessions.
6317 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
6319 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
6321 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
6323 Do not require float-time's arg to fit in time_t (Bug#11825).
6324 This works better on hosts where time_t is unsigned, and where
6325 float-time is applied to the (negative) difference between two times.
6326 * editfns.c (decode_time_components): Last arg is now double *,
6327 not int *, and means to store all the result as a double, without
6328 worrying about whether the seconds part fits in time_t.
6329 All callers changed.
6330 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
6331 All callers changed.
6332 (Ffloat_time): Do not fail merely because the specified time falls
6333 outside of time_t range.
6335 2012-07-07 Glenn Morris <rgm@gnu.org>
6337 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

6348 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
6350 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).

6352 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
6353 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
6354 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.

6357 * xfont.c (compare_font_names): Redo to omit the need for casts.
6359 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
6361 * xfns.c (Fx_change_window_property): Doc fix.
6362 * w32fns.c (Fx_change_window_property): Doc fix.
6364 * w32fns.c (Fx_window_property): Accept the same arguments as the
6365 X Windows version. Doc fix.
6366 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
6368 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
6369 Eli Zaretskii <eliz@gnu.org>
6371 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
6372 Windows-specific code from nt/config.nt moved here.
6373 Obsolete settings removed.
6375 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
6377 * process.c: Avoid unnecessary calls to gettime.
6378 (wait_reading_process_output): Don't get the time of day
6379 when gobbling data immediately and not waiting, as there's no need
6380 for it in that case. This removes a FIXME.
6382 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
6384 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
6385 is defined (Bug#11768).
6387 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6389 Fix marker debugging code.
6390 * marker.c (byte_char_debug_check): Do not perform the check
6391 if buffer is not multibyte.
6392 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
6393 Call byte_char_debug_check with correct arguments.
6395 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6397 Compile marker debugging code only if ENABLE_CHECKING is defined.
6398 * marker.c (byte_char_debug_check, count_markers):
6399 Use only if ENABLE_CHECKING is defined.
6400 (byte_debug_flag): Remove.
6401 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
6402 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
6404 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6406 Avoid code repetition in marker-related functions.
6407 * marker.c (attach_marker): New function.
6408 (Fset_marker, set_marker_restricted, set_marker_both)
6409 (set_marker_restricted_both): Use it.
6410 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
6411 Consistently rename charno to charpos.
6412 (marker_position): Add eassert.
6413 (marker_byte_position): Convert to eassert.
6415 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

6425 * lisp.h (build_marker): New prototype.
6426 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
6427 * composite.c (autocmp_chars): Likewise.
6428 * editfns.c (buildmark): Remove.
6429 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
6430 (save_restriction_save): Use build_marker.
6431 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
6432 * window.c (save_window_save): Likewise.
6434 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6436 Do not use Fdelete_overlay in delete_all_overlays
6437 to avoid redundant calls to unchain_overlay.
6438 * buffer.c (drop_overlay): New function.
6439 (delete_all_overlays, Fdelete_overlay): Use it.
6440 * minibuf.c (get_minibuffer): Fix comment.
6442 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
6444 Port to OpenBSD 5.1 amd64.
6445 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
6446 This is needed for OpenBSD, and should be harmless on all BSD systems.
6447 Also, include <sys/sysctl.h>, as it should be available on all
6448 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
6449 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
6450 use p_pid member, not kp_proc.pid.
6452 2012-07-06 Glenn Morris <rgm@gnu.org>
6454 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
6456 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
6458 More xmalloc and related cleanup.

6466 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
6467 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
6469 Omit needless casts involving void * pointers and allocation.
6470 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
6471 as the former is more robust if P's type is changed.
6472 Prefer xzalloc to xmalloc + memset 0.
6473 Simplify malloc-or-realloc to realloc.
6474 Don't worry about xmalloc returning a null pointer.
6475 Prefer xstrdup to xmalloc + strcpy.
6476 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
6478 * keyboard.c (apply_modifiers_uncached): Prefer local array to
6479 alloca of a constant.
6481 2012-07-05 Eli Zaretskii <eliz@gnu.org>
6483 * xdisp.c (display_line): Fix horizontal pixel coordinates when
6484 hscroll is larger than the line width. Fixes long and futile
6485 looping inside extend_face_to_end_of_line (on a TTY) producing
6486 glyphs that are not needed and thrown away.
6488 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
6490 * marker.c (set_marker_restricted_both): Simplify by using
6493 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>

6502 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
6503 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
6504 followed by gtk_box_set_homogeneous (Bug#11768).
6505 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
6506 (update_theme_scrollbar_width, xg_create_scroll_bar):
6507 Use gtk_scrollbar_new (Bug#11768).
6508 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
6509 (is_box_type): New function (Bug#11768).
6510 (xg_tool_item_stale_p): Call is_box_type.
6511 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
6512 with default display (Bug#11768).

6516 * xdisp.c (window_hscroll_limited): New function.
6517 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
6518 coordinates when window's hscroll is set to insanely large
6521 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
6523 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

6582 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
6584 * fileio.c (time_error_value): Check the right error number.
6585 Problem reported by Troels Nielsen in
6586 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.

6590 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
6591 This should be fixed in a better way; see Eli Zaretskii in
6592 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
6593 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
6595 * fileio.c (time_error_value): Rename from special_mtime.
6596 The old name's problems were noted by Eli Zaretskii in
6597 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
6599 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
6600 This variable's comment says Emacs needs at least one GDB-visible
6601 symbol of type enum pvec_type, to work around GDB problems.
6602 The symbol's value doesn't matter.
6604 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
6605 that causes compilation to fail on pre-C99 compilers.
6607 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
6609 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

6622 (PSEUDOVECTOR_SIZE_BITS): New constant.
6623 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
6624 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
6625 change in pvec_type.
6626 (PSEUDOVECTOR_TYPEP): New macro.
6627 (TYPED_PSEUDOVECTORP): Use it.
6628 * fns.c (internal_equal): Adapt code to extract pvectype.
6629 * emacs.c (gdb_pvec_type): Update type.
6630 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
6631 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
6632 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
6633 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
6634 (sweep_vectors): Use it. Use local var `total_bytes' instead of
6635 abusing vector->header.next.nbytes.
6636 (live_vector_p): Use PVEC_TYPE.
6637 (mark_object): Adapt code to extract pvectype. Use switch.
6639 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
6641 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
6642 Tighten new eassert a bit.
6644 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
6646 Fix compilation with --enable-gcc-warnings and -O1
6648 * doprnt.c (doprnt): Change type of tem to int, initialize
6649 to avoid compiler warning. Add eassert.
6650 * search.c (simple_search): Initialize match_byte to avoid
6651 compiler warning. Add eassert.
6653 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
6655 Avoid weird behavior with large horizontal scrolls.
6656 Without this change, for example, large hscroll values would
6657 mess up Emacs's display on Fedora 15 x86, presumably due to
6658 overflows in int calculations in the display code.
6659 Also, if buffers had long lines, Emacs would freeze.
6660 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
6661 (set_window_hscroll): New function, containing the old guts of
6662 Fset_window_hscroll. Return the clipped value.
6663 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
6664 This avoids the need to check against PTRDIFF_MAX.
6666 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
6668 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>

6672 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
6674 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
6675 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
6676 since GCC 4.4.6 issues a bogus warning for them.
6678 Fix bugs in file timestamp newness comparisons.
6679 * fileio.c (Ffile_newer_than_file_p):
6680 * lread.c (Fload): Use full timestamp resolution of files,
6681 not just the 1-second resolution, so that files that are only
6682 slightly newer still count as newer.
6683 * fileio.c (Ffile_newer_than_file_p): Don't assume file
6684 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
6686 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
6688 * fileio.c: Improve handling of file time marker. (Bug#11852)
6689 (special_mtime): New function.
6690 (Finsert_file_contents, Fverify_visited_file_modtime):
6691 Use it to set special mtime values consistently.
6693 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
6695 * fileio.c (Finsert_file_contents): Properly handle st_mtime
6696 marker for non-existing file. (Bug#11852)
6698 2012-07-03 Glenn Morris <rgm@gnu.org>
6700 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
6701 and did not make it into globals.h).
6703 2012-07-03 Tom Tromey <tromey@redhat.com>

6741 2012-07-03 Glenn Morris <rgm@gnu.org>
6743 * lisp.h (Frandom): Make it visible to C.
6744 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
6745 buffer for invisible buffers. (Bug#1229)

6749 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
6750 values which aren't power of 2.
6751 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
6752 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
6755 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
6757 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
6759 * alloc.c (mark_object): Revert part of last patch to use `switch'.
6761 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
6763 * alloc.c (allocate_vector_block): Remove redundant
6764 calls to mallopt if DOUG_LEA_MALLOC is defined.
6765 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
6766 avoid calls to mallopt if zero_vector is returned.
6768 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
6770 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
6771 is enabled, avoid dereferencing NULL current_sblock if
6774 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
6776 Cleanup basic buffer management.
6777 * buffer.h (struct buffer): Change layout to use generic vector
6778 marking code. Fix some comments. Change type of 'clip_changed'
6779 to bitfield. Remove unused #ifndef old.
6780 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
6781 (GET_OVERLAYS_AT): Fix indentation.
6782 (for_each_per_buffer_object_at): New macro.
6783 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
6784 (Fbuffer_local_variables): Use it.
6785 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
6786 * alloc.c (allocate_buffer): Adjust to match new layout of
6787 struct buffer. Fix comment.
6788 (mark_overlay): New function.
6789 (mark_buffer): Use it. Use mark_vectorlike to mark normal
6790 Lisp area of struct buffer.
6791 (mark_object): Use it. Adjust marking of misc objects
6792 and related comments.
6794 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
6796 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
6797 wrapper that is not needed because the wrapped code is a no-op (zero
6798 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
6799 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
6801 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
6803 * alloc.c (mark_buffer): Simplify. Remove prototype.
6804 (mark_object): Add comment. Reorganize marking of vector-like
6805 objects. Use CHECK_LIVE for all vector-like objects except buffers
6806 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
6807 Avoid redundant calls to mark_vectorlike for bool vectors.
6809 2012-06-30 Glenn Morris <rgm@gnu.org>
6811 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
6813 * epaths.in (PATH_SITELOADSEARCH): New.
6814 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
6815 This is rather than relying on --enable-locallisppath elements
6816 having "site-lisp" in their names. (Bug#10208#25, 11658)
6818 2012-06-30 Eli Zaretskii <eliz@gnu.org>
6820 * w32proc.c (sys_select): Accept and ignore one more argument.
6822 * w32.c (emacs_gnutls_pull): Call select with one more argument.
6824 * sysselect.h [DOS_NT]: Don't include sys/select.h.
6825 (pselect) [!MS_DOS]: Redirect to sys_select.
6827 * sysdep.c: Don't include dos.h and dosfns.h.
6829 * process.c (sys_select):
6830 * msdos.c (sys_select): Accept one more argument and ignore it.
6832 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
6833 adapt data types and code to that.
6836 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
6837 which clashes with the gnulib function of the same name.
6839 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
6841 * font.c (font_style_to_value, font_style_symbolic)
6842 (font_prop_validate_style): Add type checks for values in
6845 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
6847 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
6850 2012-06-29 Eli Zaretskii <eliz@gnu.org>
6852 * xdisp.c (try_window_id): Undo last change.
6854 * w32.c (getwd): Adjust commentary about startup_dir.
6855 (init_environment): Always call sys_access, even in non-MSVC
6856 builds. Don't chdir to the directory of the Emacs executable.
6857 This undoes code from 1997 which was justified by the need to
6858 "avoid conflicts when removing and renaming directories". But its
6859 downside was that every relative file name was being interpreted
6860 relative to the directory of the Emacs executable, which can never
6861 be TRT. In particular, it broke sys_access when called with
6862 relative file names.
6863 (sys_access): Map GetLastError to errno.
6865 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
6867 * window.h (struct window): Change type of 'fringes_outside_margins'
6868 to bitfield. Fix comment. Adjust users accordingly.
6869 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
6871 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
6874 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
6876 * gnutls.c (emacs_gnutls_handshake):
6877 Add QUIT to make the loop interruptible.
6879 2012-06-29 Glenn Morris <rgm@gnu.org>
6881 * charset.c (init_charset): Make lack of etc/charsets fatal.
6883 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
6885 * editfns.c (region_limit): Fix type mismatch.
6887 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
6889 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
6890 undefined. Convert from xassert to eassert.
6891 * nsmenu.m: Convert from xassert to eassert.
6892 * nsterm.m: Likewise.
6894 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
6896 * editfns.c (region_limit): Clip to narrowing (bug#11770).
6898 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
6900 Avoid integer overflow on scroll-left and scroll-right.
6901 * window.c (HSCROLL_MAX): New macro.
6902 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
6903 overflow when requested scroll falls outside ptrdiff_t range.
6905 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
6907 * window.h (struct window): Change type of 'hscroll',
6908 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
6909 'last_modified' and 'last_overlay_modified' to EMACS_INT.
6910 Adjust users accordingly.
6911 * xdisp.c (try_cursor_movement): Replace type check with eassert.
6912 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
6913 from EMACS_INT to ptrdiff_t.
6914 (make_window): Omit redundant initialization.
6916 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
6918 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
6920 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
6922 * window.h (struct window): Change type of 'use_time' and
6923 'sequence_number' from Lisp_Object to int.

6932 enabled with --enable-checking=[all,glyphs] configure option.
6933 Fix GLYPH_DEBUG usage assuming that it may be undefined,
6934 adjust comments accordingly.

6983 * alloc.c (allocate_string_data): Remove dead code.
6984 * xsettings.c (XSETTINGS_FONT_NAME): Move under HAVE_XFT to
6985 avoid GCC warning about unused macro.
6987 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
6989 * alloc.c (allocate_string): Omit intervals initialization.
6990 * alloc.c (make_uninit_multibyte_string): Initialize intervals
6991 as in make_pure_string and make_pure_c_string.
6993 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>

7022 2012-06-26 Eli Zaretskii <eliz@gnu.org>
7024 * s/ms-w32.h (strcasecmp, strncasecmp) [_MSC_VER]: Redirect to
7025 _stricmp and _strnicmp.

7045 2012-06-26 Dmitry Antipov <dmantipov@yandex.ru>
7047 * alloc.c: Remove build_string.
7048 * lisp.h: Define build_string as static inline. This provides
7049 a better opportunity to optimize away calls to strlen when the
7050 function is called with compile-time constant argument.
7051 * image.c (imagemagick_error): Convert to build_string.
7052 * w32proc.c (sys_spawnve): Likewise.
7053 * xterm.c (x_term_init): Likewise.
7055 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
7057 Use sprintf return value instead of invoking strlen on result.
7058 In the old days this wasn't portable, since some sprintf
7059 implementations returned char *. But they died out years ago and
7060 Emacs already assumes sprintf returns int.
7061 Similarly for float_to_string.
7062 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
7063 * ccl.c (ccl_driver):
7064 * character.c (string_escape_byte8):

7067 * print.c (print_object):
7068 * xdisp.c (message_dolog):
7069 * xfns.c (syms_of_xfns):
7070 Use sprintf or float_to_string result to avoid need to call strlen.
7071 * data.c (Fnumber_to_string):
7072 Use make_unibyte_string, since the string must be ASCII.
7073 * lisp.h, print.c (float_to_string): Now returns int length.
7074 * term.c (produce_glyphless_glyph):
7075 Use sprintf result rather than recomputing it.
7077 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
7078 * Makefile.in (ALL_CFLAGS):
7079 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.
7080 * gmalloc.c, regex.c: Include <config.h> unconditionally.

7084 * dispextern.h (xstrcasecmp): Define to library function
7085 strcasecmp if available.
7086 * xfaces.c: Do not use xstrcasecmp if strcasecmp is available.
7088 2012-06-25 Andreas Schwab <schwab@linux-m68k.org>
7090 * keyboard.c (menu_bar_items, menu_bar_item, read_key_sequence):

7101 2012-06-25 Paul Eggert <eggert@cs.ucla.edu>
7103 * gtkutil.c (get_utf8_string): Remove redundant assignment.
7104 sprintf already null-terminates its output.
7106 * xfns.c (x_window): Remove redundant cast.
7108 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
7110 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
7111 `const char *' to `char *' to avoid compiler warning.
7113 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
7115 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
7116 instead of truncating it to 63 (admittedly a generous limit).
7118 * process.c: Fix spelling and caps in comments.
7120 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
7122 * emacs.c (setpgrp): Remove definition, unused.

7132 (SYSTIME_H): Add nt/inc/sys/time.h.
7134 * systime.h [WINDOWSNT]: Include sys/time.h.
7136 * s/ms-w32.h (struct timespec): Definition moved from
7137 nt/inc/sys/time.h. Suggested by Paul Eggert <eggert@cs.ucla.edu>.
7139 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>

7168 * sound.c (sound_warning, parse_sound):
7169 Remove unnecessary forward decls.
7171 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
7173 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).
7174 * lisp.h (WAIT_READING_MAX): New macro.
7175 * dispnew.c (Fsleep_for, sit_for):
7176 * keyboard.c (kbd_buffer_get_event):
7177 * process.c (Faccept_process_output):
7178 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
7179 This improves on the previous patch, which introduced a bug
7180 when time_t is unsigned and as wide as intmax_t.
7181 See <http://bugs.gnu.org/9000#51>.
7183 2012-06-23 Eli Zaretskii <eliz@gnu.org>

7190 2012-06-23 Juanma Barranquero <lekktu@gmail.com>
7192 * makefile.w32-in: Update dependencies.
7194 * w32.c (ltime): Add return type and declare static.
7195 (w32_get_internal_run_time): Remove usused variable `time_100ns'.
7197 2012-06-23 Paul Eggert <eggert@cs.ucla.edu>
7199 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
7200 Privately reported by Herbert J. Skuhra.
7201 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
7203 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
7204 not make_lisp_timeval, when the argument is of type EMACS_TIME.
7206 2012-06-23 Eli Zaretskii <eliz@gnu.org>
7208 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in
7209 last argument of make_unibyte_string.
7211 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
7212 language ID in the event parameters.
7214 * w32term.c (w32_read_socket): Put the new keyboard codepage into
7215 event.code, not the obscure "character set ID".
7217 2012-06-23 Chong Yidong <cyd@gnu.org>
7219 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.
7221 2012-06-23 Eli Zaretskii <eliz@gnu.org>
7223 Fix the MS-Windows build broken by 2012-06-22T21:17:42Z!eggert@cs.ucla.edu.
7224 * w32.c (fdutimens): New function.
7226 * w32proc.c (sys_select): Adapt to change in the EMACS_TIME type.
7228 * s/ms-w32.h (pselect): Redirect to sys_select.
7230 * sysselect.h [WINDOWSNT]: Don't include sys/select.h.

7234 use_relocatable_buffers.
7236 2012-06-23 Paul Eggert <eggert@cs.ucla.edu>
7238 * sysdep.c [__FreeBSD__]: Fix recently-introduced typos.
7239 Privately reported by Herbert J. Skuhra.

7246 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
7248 Support higher-resolution time stamps (Bug#9000).
7249 The time stamps are only nanosecond-resolution at the C level,
7250 since that's the best that any real-world system supports now.
7251 But they are picosecond-resolution at the Lisp level, as that's
7252 easy, and leaves room for future OS improvements.
7254 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
7257 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
7258 Don't get current time unless it's needed.
7260 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
7261 now provides it if it's absent.
7262 (start_atimer): Port to higher-res time stamps.
7263 Check for time stamp overflow. Don't get current time more
7264 often than is needed.
7266 * buffer.h (struct buffer): Buffer modtime now has high resolution.
7267 Include systime.h, not time.h.
7268 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.

7313 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
7314 Port to higher-resolution time stamps. Do not assume time_t is signed.

7319 * nsterm.m (select_timeout, timeval_subtract): Remove.
7320 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,

7328 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
7330 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
7332 * lisp.h (time_overflow): New decl.
7333 (wait_reading_process_output): First arg is now intmax_t, not int,

7346 (Fprocess_attributes): Now generates ns-resolution time stamps.
7348 * sysdep.c: Include utimens.h. Don't include utime.h
7349 or worry about struct utimbuf; gnulib does that for us now.

7356 Now returns ns-resolution time stamp. All uses changed.
7357 Check for time stamp overflow.
7359 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
7360 provides a substitute now.
7362 * systime.h: Include timespec.h rather than sys/time.h and time.h,
7363 since it guarantees struct timespec.
7364 (EMACS_TIME): Now struct timespec, so that we can support
7365 ns-resolution time stamps.
7366 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
7367 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
7368 (EMACS_USECS): Remove.
7369 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
7370 so multiply the arg by 1000 before storing it.
7371 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
7373 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):

7380 (make_timeval, make_lisp_time, decode_time_components): New decls.
7381 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
7382 that it mishandled time_t overflow. You can't compare by subtracting!
7383 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
7384 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.

7411 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
7412 (timeval_subtract): Remove; no longer needed.
7413 (XTflash, XTring_bell, x_wait_for_event):
7414 Port to ns-resolution time stamps. Don't assume time_t is signed.

7420 2012-06-22 Eli Zaretskii <eliz@gnu.org>
7422 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
7423 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
7424 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
7425 staticidx goes up to 1597 out of 1600 = 0x640.)
7427 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
7429 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
7430 Otherwise, the umask might be mistakenly 0 while handling input signals.

7463 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
7464 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
7465 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
7466 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.

7473 2012-06-18 Martin Rudalics <rudalics@gmx.at>
7475 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
7476 gets killed during executing of this function (Bug#11665).
7477 Try to always return Qt when the buffer has been actually killed.
7478 (Vkill_buffer_query_functions): In doc-string say that functions
7479 run by this hook should not change the current buffer.
7481 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
7483 Fix recently-introduced process.c problems found by static checking.

7504 This removes the need for CHECK.
7505 (CHECK): Remove. Its comments about always evaluating its
7506 argument were confusing, as 'eassert' typically does not evaluate
7509 * coding.c (produce_chars): Use ptrdiff_t, not int.
7511 * xterm.c (x_draw_underwave): Check for integer overflow.
7512 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

7843 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
7845 * doprnt.c (doprnt): Truncate multibyte char correctly.
7846 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
7847 would mishandle a string argument "Xc" if X was a multibyte
7848 character of length 2: it would truncate after X's first byte
7849 rather than including all of X.
7851 2012-06-06 Chong Yidong <cyd@gnu.org>

7908 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
7911 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
7913 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
7915 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
7917 For a 'struct window', replace some Lisp_Object fields to
7918 bitfields where appropriate, remove unused fields.
7919 * window.h (struct window): Remove unused 'last_mark_x' and
7920 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
7921 change its type from Lisp_Object to bitfield.
7922 Change type of 'force_start', 'optional_new_start',
7923 'last_had_star', 'update_mode_line' and 'start_at_line_beg'

7930 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
7931 Use 'float' consistently, rather than 'float' in most places
7932 and 'double' in a couple of places.
7934 2012-05-31 Eli Zaretskii <eliz@gnu.org>
7936 * xdisp.c (handle_stop): Detect whether we have overlay strings
7937 loaded by testing it->current.overlay_string_index to be
7938 non-negative, instead of checking whether n_overlay_strings is
7939 positive. (Bug#11587)
7941 2012-05-31 Chong Yidong <cyd@gnu.org>
7943 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

7949 * search.c (search_buffer): Remove calls to
7950 r_alloc_inhibit_buffer_relocation, as it is now called by
7951 maybe_unify_char, which was the cause of relocation of buffer text
7954 2012-05-31 Eli Zaretskii <eliz@gnu.org>
7956 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
7957 for the duration of call to load_charset, to avoid problems with
7958 callers of maybe_unify_char that access buffer text through C
7961 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
7962 decrement the inhibition flag, instead of just setting or
7965 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
7967 Remove obsolete '#define static' cruft.
7968 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
7969 This #undef was "temporary" in 2000; it is no longer needed
7970 now that '#define static' has gone away.
7971 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
7972 (gray_bitmap_bits): Remove; no longer needed.
7973 All uses replaced with definiens.
7974 * xterm.c: Include "bitmaps/gray.xbm".
7976 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
7978 Clean up __executable_start, monstartup when --enable-profiling.
7979 The following changes affect the code only when profiling.
7980 * dispnew.c (__executable_start): Rename from safe_bcopy.
7981 Define only on platforms that need it.
7982 * emacs.c: Include <sys/gmon.h> when profiling.
7983 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.

7985 (safe_bcopy): Remove decl; no longer has that name.
7986 (main): Coalesce #if into single bit of code, for simplicity.

8016 Do not create empty overlays with the evaporate property (Bug#9642).
8017 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
8018 Bug#9642, but explicitly check that the buffer the overlay would
8019 be moved to is live and rearrange lines to make sure that errors
8020 will not put the overlay in an inconsistent state.
8021 (Fdelete_overlay): Cosmetics.
8023 2012-05-28 Eli Zaretskii <eliz@gnu.org>
8025 * w32term.c (my_bring_window_to_top): New function.

8040 This avoids undefined behavior that might cause the eassert
8041 to not catch an out-of-range value.
8043 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
8045 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

8059 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
8060 Only r_alloc_inhibit_buffer_relocation needed to be added;
8061 the others were already declared.
8063 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
8064 before checking whether it's out of range. Put the check inside
8066 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.

8076 defined on ralloc.c.
8078 * buffer.c [REL_ALLOC]: Remove prototypes of

8084 * search.c (search_buffer): Use it to inhibit relocation of buffer
8085 text while re_search_2 is doing its job, because re_search_2 is
8086 passed C pointers to buffer text. (Bug#11519)
8088 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
8091 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator

8096 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
8099 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
8101 Fix coding-related core dumps with gcc -ftrapv.
8102 The code was computing A - B, where A and B are pointers, and B is
8103 random garbage. This can lead to core dumps on platforms that
8104 have special pointer registers, and it also leads to core dumps on
8105 x86-64 when compiled with gcc -ftrapv. The fix is to compute
8106 A - B only when B is initialized properly.
8107 * coding.c (coding_set_source, coding_set_destination): Return void.
8108 (coding_change_source, coding_change_destinations): New functions,
8109 with the old behaviors of coding_set_source and coding_set_destination.

8114 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
8116 2012-05-26 Eli Zaretskii <eliz@gnu.org>

8119 * xdisp.c (draw_row_with_mouse_face):
8120 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
8122 * w32console.c: Include window.h.
8123 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
8125 (initialize_w32_display): Initialize mouse-highlight data.
8127 * w32inevt.c: Include termchar.h and window.h.
8128 (do_mouse_event): Support mouse-autoselect-window. When the mouse
8129 moves, call note_mouse_highlight. If help_echo changed, call
8130 gen_help_event to produce help-echo message in the echo area.
8131 Call clear_mouse_face if mouse_face_hidden is set in the mouse
8134 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
8136 * lread.c (read1): Simplify slightly to avoid an overflow warning

8180 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

8187 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
8188 Omit pointer cast, which isn't needed anyway, and doesn't work
8189 after the EMACS_INT -> ptrdiff_t change.
8190 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
8191 * buffer.h: Adjust decls to match defn changes elsewhere.

8196 not int, to avoid needless 32-bit limit on 64-bit hosts.
8197 (exec_byte_code): Use tighter memory-full test, one that checks
8198 for alloca overflow. Don't compute the address of the object just
8199 before an array, as that's not portable. Use EMACS_INT, not
8200 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
8201 * callint.c (Fcall_interactively):
8202 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

8213 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
8214 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8215 (casify_object): Avoid integer overflow when overallocating buffer.
8216 * casetab.c (set_identity, shuffle): Prefer int to unsigned when

8219 * category.h (CATEGORYP): Don't assume arg is nonnegative.
8220 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
8221 integers are now checked earlier. All uses replaced with XINT.
8223 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8224 For CCL_MapSingle, check that content and value are in int range.
8225 (ccl_driver, Fregister_code_conversion_map):
8226 Check that Vcode_version_map_vector is a vector.
8227 (resolve_symbol_ccl_program): Check that vector header is in range.
8228 Always copy the vector, so that we can check its contents reliably
8229 now rather than having to recheck each instruction as it's being
8230 executed. Check that vector words fit in 'int'.
8231 (ccl_get_compiled_code, Fregister_ccl_program)
8232 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
8233 program indexes, to avoid needless 32-bit limit on 64-bit hosts.

8235 contents are in range.
8236 (Fccl_execute_on_string): Check that status is in range.
8237 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
8238 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
8239 Accept and return EMACS_INT, not int, because callers can pass values

8246 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

8248 avoid mishandling large integers.

8260 Don't assume unsigned int fits into fixnum, or that fixnum fits
8261 into unsigned int. Don't require max_code to be a valid fixnum;
8262 that's not true for gb10830 4-byte on a 32-bit host. Allow
8263 invalid_code to be a cons, for the same reason. Require code_offset
8264 to be a character. Avoid int overflow if max_char is close

8267 this is intended anyway and avoids some undefined behavior.

8269 INDEX_TO_CODE_POINT, as that's what it expects.
8270 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
8271 * charset.h (DECODE_CHAR): Return int, not unsigned;
8272 this is what was intended anyway, and it avoids undefined behavior.
8273 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
8274 integer-overflow issues.

8276 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
8277 where the argument is EMACS_INT, and this behavior is not intended.
8278 * chartab.c (Fmake_char_table, Fset_char_table_range)
8279 (uniprop_get_decoder, uniprop_get_encoder):
8280 Don't assume fixnum fits in int.
8281 * cmds.c (move_point): New function, that does the gist of
8282 Fforward_char and Fbackward_char, but does so while checking
8283 for integer overflow more accurately.
8284 (Fforward_char, Fbackward_char): Use it.
8285 (Fforward_line, Fend_of_line, internal_self_insert)
8286 (internal_self_insert):
8287 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

8895 (start_hourglass): Use duration_to_sec_usec to do proper
8896 overflow checking on durations.
8897 * xfaces.c (Fbitmap_spec_p):
8898 Check that fixnums are in proper range for system types.
8899 (compare_fonts_by_sort_order):
8900 Avoid mishandling comparisons due to subtraction overflow.

8905 Use SAFE_ALLOCA_LISP, not alloca.
8906 (merge_face_heights): Remove unnecessary cast to EMACS_INT.

8909 (face_at_string_position):
8910 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8911 (merge_faces): Use int, not EMACS_INT, where int is wide enough.
8912 * xfns.c (x_set_menu_bar_lines, x_set_tool_bar_lines, x_icon_verify)
8914 Check that fixnums are in proper range for system types.
8915 (Fx_create_frame, x_create_tip_frame, Fx_show_tip)

8928 (x_get_local_selection, x_reply_selection_request)
8929 (x_handle_selection_request, wait_for_property_change):
8930 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
8931 (selection_data_to_lisp_data): Use short, not EMACS_INT, where
8932 short is wide enough.
8933 (x_send_client_event): Don't assume fixnum fits in int.
8934 * xterm.c (x_x_to_emacs_modifiers):
8935 Don't assume EMACS_INT overflows nicely into int.
8936 (x_emacs_to_x_modifiers): Use EMACS_INT, not int, because values
8938 (handle_one_xevent): NATNUMP can eval its arg twice.
8939 (x_connection_closed):
8940 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
8941 * xterm.h: Adjust decls to match defn changes elsewhere.
8942 (struct scroll_bar): Use struct vectorlike_header
8943 rather than rolling our own approximation.
8944 (SCROLL_BAR_VEC_SIZE): Remove; not used.
8946 2012-05-25 Glenn Morris <rgm@gnu.org>
8948 * lisp.mk (lisp): Update for more files being compiled now.
8950 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>

8953 (read_pure): Remove var.
8954 (unreadpure): Remove function.
8955 (readevalloop): Don't call read_list with -1 flag.
8956 (read1, read_vector): Don't test read_pure any more.
8957 (read_list): Simplify.
8959 * fileio.c, character.h: Minor style tweaks.

8970 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
8973 This directory predates autoconf and is no longer needed nowadays.
8974 Move its few remaining bits of functionality to where they're needed.
8975 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:

8980 * lisp.h (USE_LSB_TAG):
8981 * mem-limits.h (EXCEEDS_LISP_PTR):
8982 Use VAL_MAX, not VALBITS, in #if.
8983 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
8984 (EMACS_UINT): Define unconditionally now.
8985 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
8986 (BITS_PER_EMACS_INT): New constants, replacing
8987 what used to be in config.h, but not useful in #if.
8988 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
8989 define them any more.
8990 (VAL_MAX): New macro.
8992 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
8993 BITS_PER_EMACS_INT, in #if.
8994 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
8995 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
8996 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
8997 * s/ms-w32.h (DATA_START):
8998 Move here from removed file m/intel386.h.
8999 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
9000 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
9002 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
9004 Assume C89 or later.
9005 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.

9012 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
9013 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
9014 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
9015 * xterm.c (input_signal_count): Assume volatile works.
9017 2012-05-21 Ken Brown <kbrown@cornell.edu>
9019 * xgselect.c (xg_select): Fix first argument in call to 'select'
9022 2012-05-20 Ken Brown <kbrown@cornell.edu>
9024 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
9025 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
9027 2012-05-19 Ken Brown <kbrown@cornell.edu>
9029 * xfns.c (x_in_use): Remove `static' qualifier.
9030 * xterm.h (x_in_use): Declare.
9031 * xgselect.c: Include xterm.h.
9032 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
9033 and `display_arg' (bug#9754).
9035 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
9037 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
9039 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
9040 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
9042 2012-05-18 Eli Zaretskii <eliz@gnu.org>
9044 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.

9047 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
9049 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
9050 reference to image_cache->refcount.
9051 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
9053 2012-05-17 Juri Linkov <juri@jurta.org>
9055 * search.c (Fword_search_regexp, Fword_search_backward)
9056 (Fword_search_forward, Fword_search_backward_lax)
9057 (Fword_search_forward_lax): Move functions to isearch.el
9058 (bug#10145, bug#11381).
9060 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
9062 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
9064 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
9066 * lread.c (init_obarray): Declare Qt and Qnil as special.
9068 2012-05-14 Glenn Morris <rgm@gnu.org>
9070 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
9071 Put "libexec" before "bin", for the sake of init_callproc_1.
9073 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
9075 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
9077 * unexaix.c: Port to more-recent AIX compilers.
9078 (report_error, report_error_1, make_hdr, copy_sym)
9079 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
9080 Make arguments const char *, not char *, to avoid violations of C
9081 standard and to fix some AIX warnings reported by Gilles Pion.
9083 2012-05-14 Eli Zaretskii <eliz@gnu.org>
9085 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
9086 already have overlays loaded.
9087 (handle_single_display_spec): Before returning without displaying
9088 fringe bitmap, synchronize the bidi iterator with the main display
9089 iterator, by calling iterate_out_of_display_property.
9090 (iterate_out_of_display_property): Detect buffer iteration by
9091 testing that it->string is a Lisp string.
9092 (get_next_display_element): When the current object is exhausted,
9093 and there's something on it->stack, call set_iterator_to_next to
9094 proceed with what's on the stack, instead of returning zero.
9095 (set_iterator_to_next): If called at the end of a Lisp string,
9096 proceed to consider_string_end without incrementing string
9097 position. Don't increment display vector index past the end of
9098 the display vector. (Bug#11417)
9099 (pos_visible_p): Don't report a position visible when move_it_to
9100 stopped at the last line of window, which happens to be scanned
9101 backwards by the bidi iteration. (Bug#11464)
9103 2012-05-14 Eli Zaretskii <eliz@gnu.org>
9105 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
9106 and right-margin display specs even if the spec is invalid or we
9107 are on a TTY, and thus unable to display on the fringes.
9108 That's because the text with the property will not be displayed anyway,
9109 so we need to signal to the caller that this is a "replacing"
9110 display spec. This fixes display when the spec is invalid or we
9113 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
9115 * unexaix.c (make_hdr): Fix typo in prototype.
9116 This bug broke the build on AIX. Problem reported by Gilles Pion.
9118 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
9120 * keyboard.c (kbd_buffer_get_event): Read special events also in
9121 batch mode. (Bug#11415)
9123 2012-05-12 Glenn Morris <rgm@gnu.org>
9125 * ns.mk: Update for ns_appbindir no longer having trailing "/".
9127 2012-05-12 Eli Zaretskii <eliz@gnu.org>
9129 * lisp.mk (lisp): Add newcomment.elc.
9131 2012-05-12 Glenn Morris <rgm@gnu.org>
9133 * Makefile.in (MKDIR_P): New, set by configure.
9134 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
9136 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
9138 Remove unused function hourglass_started.
9139 * dispextern.h (hourglass_started):
9140 * w32fns.c (hourglass_started):
9141 * xdisp.c (hourglass_started): Remove.
9143 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
9145 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
9146 Update dependencies.
9148 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
9150 * xgselect.c (xg_select): Put maxfds+1 into a var.
9151 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
9153 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
9155 2012-05-10 Dave Abrahams <dave@boostpro.com>
9157 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
9158 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
9160 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
9162 * dbusbind.c (xd_registered_buses): New internal Lisp object.
9163 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
9164 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
9165 Initialize xd_registered_buses.
9167 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
9169 Untag more efficiently if USE_LSB_TAG.
9170 This is based on a proposal by YAMAMOTO Mitsuharu in
9171 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
9172 For an admittedly artificial (nth 8000 longlist) benchmark on
9173 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
9174 Emacs's overall text size by 1%.
9175 * lisp.h (XUNTAG): New macro.
9176 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
9177 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
9178 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
9179 * eval.c (Fautoload):
9180 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
9181 * frame.h (XFRAME): Use XUNTAG.
9183 Port recent dbusbind.c changes to 32-bit --with-wide-int.
9184 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
9185 Remove unportable assumptions about print widths of types like
9187 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
9188 intptr_t when converting between pointer and integer, to avoid GCC
9189 warnings about wrong width.
9191 2012-05-09 Eli Zaretskii <eliz@gnu.org>
9193 * w32proc.c (new_child): Force Windows to reserve only 64KB of
9194 stack for each reader_thread, instead of defaulting to 8MB
9195 determined by the linker. This avoids failures in creating
9196 subprocesses on Windows 7, see the discussion in this thread:
9197 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
9199 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
9201 Fix up display of the *Minibuf-0* buffer in the mini window.
9202 * keyboard.c (read_char): Don't clear the echo area if there's no
9204 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
9205 contents of *Minibuf-0*) if there's no message displayed in its stead.
9207 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
9209 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
9212 2012-05-06 Chong Yidong <cyd@gnu.org>
9214 * lisp.mk (lisp): Update.
9216 2012-05-05 Jim Meyering <meyering@redhat.com>
9218 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
9220 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
9222 * data.c (PUT_ERROR): New macro.
9223 (syms_of_data): Use it. Add new error type `user-error'.
9224 * undo.c (user_error): New function.
9225 (Fprimitive_undo): Use it.
9226 * print.c (print_error_message): Adjust print style for `user-error'.
9227 * keyboard.c (user_error): New function.
9228 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
9230 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
9232 Do not limit current-time-string to years 1000..9999.
9233 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
9234 (Fcurrent_time_string): Support any year that is supported by the
9235 underlying localtime representation. Don't use asctime, as it
9236 has undefined behavior for years outside the range -999..9999.
9238 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
9240 Fix race conditions involving setenv, gmtime, localtime, asctime.
9241 Without this fix, interrupts could mess up code that uses these
9242 nonreentrant functions, since setting TZ invalidates existing
9243 tm_zone or tzname values, and since most of these functions return
9244 pointers to static storage.
9245 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
9246 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
9247 Grow the critical sections to include not just invoking
9248 localtime/gmtime, but also accessing these functions' results
9249 including their tm_zone values if any, and any related TZ setting.
9250 (format_time_string): Last arg is now struct tm *, not struct tm **,
9251 so that the struct tm is saved in the critical section.
9252 All callers changed. Simplify allocation of initial buffer, partly
9253 motivated by the fact that memory allocation needs to be outside
9254 the critical section.
9256 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
9258 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
9259 with RESET_INTERVAL.
9261 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
9262 Remove duplicated buffer name initialization.
9264 2012-05-02 Jim Meyering <jim@meyering.net>
9266 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
9268 * xfns.c (x_window): Use xstrdup (Bug#11375).
9270 2012-05-02 Eli Zaretskii <eliz@gnu.org>
9272 * xdisp.c (pos_visible_p): If already at a newline from the
9273 display string before the 'while' loop, don't walk back the glyphs
9274 from it3.glyph_row. Solves assertion violation when the display
9275 string begins with a newline (egg.el). (Bug#11367)
9277 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
9279 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
9282 2012-05-01 Glenn Morris <rgm@gnu.org>
9284 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
9285 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
9286 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
9287 All were removed before 23.1.
9289 * dispnew.c: Remove HAVE_LIBNCURSES test;
9290 it is always true on relevant platforms.
9292 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
9293 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
9295 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
9297 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
9299 * .gdbinit (xpr): Remove checks for no longer existing misc types.
9300 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
9303 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
9305 Do not avoid creating empty evaporating overlays (Bug#9642).
9306 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
9307 That is, do not delete an evaporating overlay if it becomes
9308 empty after its bounds are adjusted to fit within its buffer.
9309 This fix caused other problems, and I'm reverting it until we get
9310 to the bottom of them.
9312 2012-04-27 Chong Yidong <cyd@gnu.org>
9314 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
9316 2012-04-27 Eli Zaretskii <eliz@gnu.org>
9318 * xdisp.c (pos_visible_p): If the window start position is beyond
9319 ZV, start the display from buffer beginning. Prevents assertion
9320 violation in init_iterator when the minibuffer window is scrolled
9323 * window.c (window_scroll_pixel_based): Likewise.
9325 2012-04-27 Chong Yidong <cyd@gnu.org>
9327 * keymap.c (where_is_internal): Doc fix (Bug#10872).
9329 2012-04-27 Glenn Morris <rgm@gnu.org>
9331 * fileio.c (Fcopy_file, Fset_file_selinux_context):
9332 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
9334 2012-04-27 Eli Zaretskii <eliz@gnu.org>
9336 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
9337 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
9339 2012-04-26 Eli Zaretskii <eliz@gnu.org>
9341 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
9342 display element, check also the underlying string or buffer
9343 character. (Bug#11341)
9345 * w32menu.c: Include w32heap.h.

9371 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
9373 Do not create empty overlays with the evaporate property (Bug#9642).
9374 * buffer.c (Fmove_overlay): Delete an evaporating overlay
9375 if it becomes empty after its bounds are adjusted to fit within
9376 its buffer. Without this fix, in a nonempty buffer (let ((o
9377 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
9378 yields an empty overlay that has the evaporate property, which is
9379 not supposed to happen.

9483 since the two debugging options are incompatible.
9484 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
9486 (mem_init, mem_insert, mem_insert_fixup):
9487 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

9519 (print_object): Check for cycles even when print-circle is nil and
9520 print-gensym is t, but only check print_depth if print-circle is nil.
9522 2012-04-20 Chong Yidong <cyd@gnu.org>
9524 * process.c (wait_reading_process_output): If EIO occurs on a pty,
9525 set the status to "failed" and ensure that sentinel is run.

9580 New extern decls, to avoid calling undeclared functions.
9581 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
9582 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
9583 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
9584 (NEED_MEM_INSERT): New macro.
9585 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
9586 Remove one incorrect comment and fix another.

9600 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
9601 Remove decls. This fixes an "It stinks!".

9605 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
9607 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

9623 * s/netbsd.h, s/sol2-6.h:
9624 Remove definition of GC_MARK_STACK, since the default now works.
9625 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
9626 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
9627 no longer the default.
9628 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
9630 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

9653 2012-04-11 Daniel Colascione <dancol@dancol.org>
9655 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
9656 against is gone. It's better to use vfork now so that when Cygwin
9657 gains a new, working vfork, we use it automatically (bug#10398).
9659 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

9680 being loaded (bug#10424).
9682 2012-04-09 Glenn Morris <rgm@gnu.org>
9684 * doc.c (Fsnarf_documentation): Check variables, functions are bound,

9714 2012-04-09 Eli Zaretskii <eliz@gnu.org>
9716 * xdisp.c (set_cursor_from_row): If the display string appears in
9717 the buffer at position that is closer to point than the position
9718 after the display string, display the cursor on the first glyph of
9719 the display string. Fixes cursor display when a 'display' text
9720 property immediately follows invisible text. (Bug#11094)
9722 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
9724 composite.c: use 'double' consistently
9725 * composite.c (get_composition_id): Use 'double' consistently
9726 instead of converting 'float' to 'double' and vice versa; this is
9727 easier to understand and avoids a GCC warning.
9729 2012-04-09 Glenn Morris <rgm@gnu.org>
9731 * Makefile.in: Generate leim-list with bootstrap-emacs, in
9732 preparation for dumping it with emacs. (Bug#4789)

9776 [!WINDOWSNT]: New macros.
9777 (init_libxml2_functions, libxml2_loaded_p): New functions.
9778 (parse_region): Call fn_xmlCheckVersion instead of using the macro
9779 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
9780 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
9781 Calls xmlCleanupParser only if libxml2 was loaded (or statically
9783 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
9784 Call init_libxml2_functions before calling libxml2 functions.
9785 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
9787 * emacs.c: Don't include libxml/parser.h.

9789 xmlCleanupParser directly.
9791 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
9793 2012-04-07 Eli Zaretskii <eliz@gnu.org>
9795 * indent.c (Fvertical_motion): If there is a display string at
9796 point, use it.vpos to compute how many lines to backtrack after
9797 move_it_to point. (Bug#11133)
9799 2012-04-06 Eli Zaretskii <eliz@gnu.org>
9801 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
9802 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
9803 about subtle differences between FETCH_CHAR* and STRING_CHAR*
9804 macros related to unification of CJK characters. For the details,
9805 see the discussion following the message here:
9806 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
9808 2012-04-04 Chong Yidong <cyd@gnu.org>
9810 * keyboard.c (Vdelayed_warnings_list): Doc fix.
9812 2012-04-01 Eli Zaretskii <eliz@gnu.org>
9814 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
9815 instead of alloca. (Bug#11138)
9817 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
9819 * w32menu.c (is_simple_dialog): Properly check lisp types.
9822 2012-03-31 Eli Zaretskii <eliz@gnu.org>
9824 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
9825 position we get to after a call to move_it_to fails the
9826 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
9827 only if we wind up in a string from display property. (Bug#11063)
9829 * window.c (Fdelete_other_windows_internal): Invalidate the row
9830 and column information about mouse highlight, so that redisplay
9831 restores it after reallocating the glyph matrices. (Bug#7464)
9833 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
9834 string comes from a `display' text property, use the buffer
9835 position of that property as if we actually saw that position in
9837 (move_it_by_lines): Remove the assertion that
9838 "it->current_x == 0 && it->hpos == 0" which can be legitimately
9839 violated when there's a before-string at the beginning of a line.
9842 2012-03-30 Eli Zaretskii <eliz@gnu.org>
9844 * xdisp.c (append_space_for_newline): If the default face was
9845 remapped, use the remapped face for the appended newline.
9846 (extend_face_to_end_of_line): Use the remapped default face for
9847 extending the face to the end of the line.
9848 (display_line): Call extend_face_to_end_of_line when the default
9849 face was remapped. (Bug#11068)
9851 2012-03-29 Eli Zaretskii <eliz@gnu.org>
9853 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
9855 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
9857 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
9859 2012-03-27 Glenn Morris <rgm@gnu.org>
9861 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
9864 2012-03-26 Kenichi Handa <handa@m17n.org>
9866 * dispextern.h (struct glyph): Fix previous change. Change the
9867 bit length of glyphless.ch to 25 (Bug#11082).
9869 2012-03-26 Chong Yidong <cyd@gnu.org>
9871 * keyboard.c (Vselection_inhibit_update_commands): New variable.
9872 (command_loop_1): Use it; inhibit selection update for
9873 handle-select-window too (Bug#8996).
9875 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
9877 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
9879 2012-03-25 Kenichi Handa <handa@m17n.org>
9881 * dispextern.h (struct glyph): Change the bit length of
9882 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
9884 2012-03-24 Eli Zaretskii <eliz@gnu.org>
9886 * s/ms-w32.h (tzname): Include time.h before redirecting to
9887 _tzname. Fixes the MSVC build. (Bug#9960)
9889 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
9891 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
9894 * xterm.c (XTread_socket): Only modify handling_signal if
9895 !SYNC_INPUT. (Bug#11080)
9897 2012-03-23 Eli Zaretskii <eliz@gnu.org>
9899 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
9900 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
9901 when fetching a multibyte character consumes more bytes than
9902 CHAR_BYTES returns, due to unification of CJK characters in
9903 string_char. (Bug#11073)
9905 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
9907 * process.c (wait_reading_process_output): Handle pty disconnect
9908 by refraining from sending oneself a SIGCHLD (bug#10933).
9910 2012-03-22 Chong Yidong <cyd@gnu.org>
9912 * dispextern.h (struct it): New member string_from_prefix_prop_p.
9914 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
9915 Mark string as coming from a prefix property.
9916 (handle_face_prop): Use default face for prefix strings (Bug#4281).
9917 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
9919 2012-03-21 Chong Yidong <cyd@gnu.org>
9921 * xfaces.c (Vface_remapping_alist): Doc fix.
9923 2012-03-20 Eli Zaretskii <eliz@gnu.org>
9925 * w32proc.c (Fw32_set_console_codepage)
9926 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
9929 2012-03-20 Chong Yidong <cyd@gnu.org>
9931 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
9932 to reflect default non-nil value of redisplay-dont-pause.
9934 2012-03-19 Kenichi Handa <handa@m17n.org>
9936 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
9937 it fit in a valid range (Bug#11003).
9939 2012-03-18 Eli Zaretskii <eliz@gnu.org>
9941 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
9942 that is not from display property, accept the row as a "cursor
9943 row" if one of the string's character has a non-nil `cursor'
9944 property. Fixes cursor positioning when there are newlines in
9945 overlay strings, e.g. in icomplete.el. (Bug#11035)
9947 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
9949 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
9951 2012-03-12 Chong Yidong <cyd@gnu.org>
9953 * eval.c (inhibit_lisp_code): Rename from
9954 inhibit_window_configuration_change_hook; move from window.c.
9956 * xfns.c (unwind_create_frame_1, Fx_create_frame):
9957 * window.c (run_window_configuration_change_hook)
9958 (syms_of_window): Callers changed.
9960 2012-03-11 Chong Yidong <cyd@gnu.org>
9962 * keymap.c (Fkey_description): Doc fix (Bug#9700).
9964 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
9966 2012-03-10 Chong Yidong <cyd@gnu.org>
9968 * frame.c (other_visible_frames): Don't assume the selected frame
9969 is visible (Bug#10955).
9971 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
9973 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
9975 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
9977 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
9978 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
9981 2012-03-03 Glenn Morris <rgm@gnu.org>
9983 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
9985 2012-03-02 Eli Zaretskii <eliz@gnu.org>
9987 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
9988 position past the first glyph_row that ends at ZV. (Bug#10902)
9989 (redisplay_window, next_element_from_string): Fix typos in
9991 (redisplay_window): Pass to move_it_vertically the margin in
9992 pixels, not in screen lines.
9994 2012-03-02 Glenn Morris <rgm@gnu.org>
9996 * buffer.c (buffer-list-update-hook): Doc fix.
9998 2012-02-29 Eli Zaretskii <eliz@gnu.org>
10000 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
10001 push_it before setting up the iterator for the first overlay
10002 string, even if we have an empty string loaded.
10003 (next_overlay_string): If there's an empty string on the iterator
10004 stack, pop the stack. (Bug#10903)
10006 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
10008 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
10009 Suggested by Stefan Monnier in
10010 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
10011 * alloc.c (widen_to_Lisp_Object): New static function.
10012 (mark_memory): Also mark Lisp_Objects by fetching pointer words
10013 and widening them to Lisp_Objects. This would work even if
10014 USE_LSB_TAG is defined and wide integers are used, which might
10015 happen in a future version of Emacs.
10017 2012-02-25 Chong Yidong <cyd@gnu.org>
10019 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
10022 * xselect.c (Fx_selection_exists_p): Doc fix.
10023 (x_clipboard_manager_save_all): Print an informative message
10024 before saving to clipboard manager.
10026 2012-02-24 Chong Yidong <cyd@gnu.org>
10028 * keyboard.c (process_special_events): Handle all X selection
10029 requests in kbd_buffer, not just the next one (Bug#8869).
10031 2012-02-23 Chong Yidong <cyd@gnu.org>
10033 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
10034 call when setting menu-bar-lines and tool-bar-lines parameters.
10035 (unwind_create_frame_1): New helper function.
10037 * window.c (inhibit_window_configuration_change_hook): New var.
10038 (run_window_configuration_change_hook): Obey it.
10039 (syms_of_window): Initialize it.
10041 2012-02-22 Chong Yidong <cyd@gnu.org>
10043 * xterm.c (x_draw_image_relief): Add missing type check for
10044 Vtool_bar_button_margin (Bug#10743).
10046 2012-02-21 Chong Yidong <cyd@gnu.org>
10048 * fileio.c (Vfile_name_handler_alist): Doc fix.
10050 * buffer.c (Fget_file_buffer): Protect against invalid file
10051 handler return value.
10053 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
10055 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
10056 when computing $valmask.
10058 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
10059 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
10060 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
10061 It's useless in that case, and it can cause problems on hosts
10062 that allocate halves of EMACS_INT values separately.
10063 Reported by Dan Horák. Diagnosed by Andreas Schwab in
10064 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
10065 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
10066 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
10067 it avoids undefined behavior on hosts where shifting right by more
10068 than the word width has undefined behavior.
10070 2012-02-19 Chong Yidong <cyd@gnu.org>
10072 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
10073 (Funhandled_file_name_directory, Ffile_name_as_directory)
10074 (Fdirectory_file_name, Fexpand_file_name)
10075 (Fsubstitute_in_file_name): Protect against invalid file handler
10076 return values (Bug#10845).
10078 2012-02-18 Eli Zaretskii <eliz@gnu.org>
10080 * .gdbinit (pitx): Fix incorrect references to fields of the
10083 2012-02-17 Chong Yidong <cyd@gnu.org>

10087 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>
10089 * image.c (MAX_IMAGE_SIZE): Increase from 6.0 to 10.0; see
10090 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
10092 2012-02-15 Chong Yidong <cyd@gnu.org>
10094 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
10095 marked as special. Also, starting docstrings with * is obsolete.
10097 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
10099 * gnutls.c (emacs_gnutls_write): Fix last change.
10101 2012-02-13 Lars Ingebrigtsen <larsi@gnus.org>
10103 * gnutls.c (emacs_gnutls_write): Set errno appropriately for
10106 2012-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
10108 * keymap.c (Fsingle_key_description): Handle char ranges.
10110 2012-02-12 Chong Yidong <cyd@gnu.org>
10112 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
10113 as that creates a dangerous corner case.
10115 * window.c (Fdelete_window_internal): Invalidate the mouse
10116 highlight (Bug#9904).
10118 2012-02-12 Glenn Morris <rgm@gnu.org>
10120 * xselect.c (Fx_own_selection_internal)
10121 (Fx_get_selection_internal, Fx_disown_selection_internal)
10122 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
10123 * nsselect.m (Fx_own_selection_internal)
10124 (Fx_disown_selection_internal, Fx_selection_exists_p)
10125 (Fx_selection_owner_p, Fx_get_selection_internal):
10126 Sync docs and argument specs with the xselect.c versions.
10128 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
10130 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
10132 2012-02-11 Eli Zaretskii <eliz@gnu.org>
10134 * w32select.c (Fx_selection_exists_p): Sync doc string and
10135 argument list with xselect.c. (Bug#10783)
10137 * w16select.c (Fx_selection_exists_p): Sync doc string and
10138 argument list with xselect.c. (Bug#10783)
10140 2012-02-10 Glenn Morris <rgm@gnu.org>
10142 * fns.c (Fsecure_hash): Doc fix.
10144 2012-02-09 Kenichi Handa <handa@m17n.org>
10146 * coding.c (produce_chars): Fix updating of src_end (Bug#10701).
10148 2012-02-07 Chong Yidong <cyd@gnu.org>
10150 * buffer.c (Fbuffer_local_variables)
10151 (buffer_lisp_local_variables): Handle unbound vars correctly;
10152 don't let Qunbound leak into Lisp.
10154 2012-02-07 Glenn Morris <rgm@gnu.org>
10156 * image.c (Fimagemagick_types): Doc fix.
10158 * image.c (imagemagick-render-type): Change it from a lisp object
10159 to an integer. Move the doc here from the lisp manual.
10160 Treat all values not equal to 0 the same.
10162 2012-02-06 Chong Yidong <cyd@gnu.org>
10164 * doc.c (store_function_docstring): Avoid applying docstring of
10165 alias to base function (Bug#2603).
10167 2012-02-04 Andreas Schwab <schwab@linux-m68k.org>
10169 * .gdbinit (pp1, pv1): Remove redundant defines.
10172 2012-02-04 Chong Yidong <cyd@gnu.org>
10174 * nsterm.m: Declare a global (Bug#10694).
10176 2012-02-04 Eli Zaretskii <eliz@gnu.org>
10178 * w32.c (get_emacs_configuration_options):
10179 Include --enable-checking, if specified, in the return value.
10181 2012-02-04 Martin Rudalics <rudalics@gmx.at>
10183 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
10184 after rounding frame sizes. (Bug#9723)
10186 2012-02-04 Eli Zaretskii <eliz@gnu.org>
10188 * keyboard.c (adjust_point_for_property): Don't position point
10189 before BEGV. (Bug#10696)
10191 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
10193 Handle overflow when computing char display width (Bug#9496).
10194 * character.c (char_width): Return EMACS_INT, not int.
10195 (char_width, c_string_width): Check for overflow when
10196 computing the width; this is possible now that individual
10197 characters can have unbounded width. Problem introduced
10198 by merge from Emacs 23 on 2012-01-19.
10200 2012-02-02 Michael Albinus <michael.albinus@gmx.de>
10202 * dbusbind.c (Fdbus_register_method): Mention the return value
10203 :ignore in the docstring.
10205 2012-02-02 Glenn Morris <rgm@gnu.org>
10207 * callproc.c (Fcall_process, Fcall_process_region): Doc fix.
10209 * nsterm.m (syms_of_nsterm) <x-toolkit-scroll-bars>:
10210 Unconditionally set to t. (Bug#10673)

10212 * w32term.c (syms_of_w32term) <x-toolkit-scroll-bars>:
10213 * xterm.c (syms_of_xterm) <x-toolkit-scroll-bars>: Doc fix.
10215 2012-02-02 Kenichi Handa <handa@m17n.org>
10217 (x_produce_glyphs): Cancel previous change. If cmp->glyph_len is
10218 0, do not call append_composite_glyph.
10220 2012-02-02 Kenichi Handa <handa@m17n.org>
10222 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
10224 (x_produce_glyphs): If the component of a composition is a null
10225 string, set it->pixel_width to 1 to avoid zero-width glyph.
10227 2012-02-01 Eli Zaretskii <eliz@gnu.org>
10229 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
10230 first 2 arguments are identical. This makes inserting large
10231 output from a subprocess an order of magnitude faster on
10232 MS-Windows, where all sbrk'ed memory is always contiguous.
10234 2012-01-31 Glenn Morris <rgm@gnu.org>
10236 * nsterm.m (syms_of_nsterm) <x-toolkit-scroll-bars>:

10240 2012-01-29 Glenn Morris <rgm@gnu.org>
10242 * gnutls.c (syms_of_gnutls): More doc (from etc/NEWS).
10244 2012-01-28 Samuel Thibault <sthibault@debian.org> (tiny change)
10246 * s/gnu.h: Define POSIX_SIGNALS (Bug#10552).
10248 2012-01-28 Chong Yidong <cyd@gnu.org>
10250 * minibuf.c (syms_of_minibuf): Doc fix (Bug#10550).

10268 2012-01-25 Chong Yidong <cyd@gnu.org>
10270 * eval.c (Fuser_variable_p): Doc fix; mention custom-variable-p.
10272 2012-01-21 Chong Yidong <cyd@gnu.org>
10274 * floatfns.c (Fcopysign): Make the second argument non-optional,
10275 since nil is not allowed anyway.
10277 2012-01-21 Andreas Schwab <schwab@linux-m68k.org>
10279 * process.c (read_process_output): Use p instead of XPROCESS (proc).
10280 (send_process): Likewise.
10282 2012-01-19 Martin Rudalics <rudalics@gmx.at>
10284 * window.c (save_window_save, Fcurrent_window_configuration)
10285 (Vwindow_persistent_parameters): Do not use Qstate.

10762 * xdisp.c (redisplay_window): If cursor row is not fully visible
10763 after recentering, and scroll-conservatively is set to a large
10764 number, scroll window by a few more lines to make the cursor fully
10765 visible and out of scroll-margin. (Bug#10105)
10766 (start_display): Don't move to the next line if the display should
10767 start at a newline that is part of a display vector or an overlay
10768 string. (Bug#10119)

10847 Standardize on VIRT_ADDR_VARIES behavior (Bug#10042).
10848 Otherwise, valgrind does not work on some platforms.
10849 Problem reported by Andreas Schwab in
10850 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
10851 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
10852 is set, removing the need for VIRT_ADDRESS_VARIES.
10853 (PURE_P): Use a more-efficient implementation that needs just one
10854 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
10855 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
10856 to 4 (xorl, subq, cmpq, setbe).
10857 * alloc.c (pure): Always extern now, since that's the
10858 VIRT_ADDR_VARIES behavior.

10860 consistency with the new puresize.h.
10861 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
10862 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

10868 (erase_phys_cursor, update_window_cursor, show_mouse_face)
10869 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
10870 behave as if the cursor position were at the window margin.
10872 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
10873 and the cursor position is out of bounds, behave as if the cursor
10874 position were at the window margin. (Bug#10075)
10876 2011-11-18 Chong Yidong <cyd@gnu.org>
10878 * window.c (Fwindow_combination_limit): Make first argument

10897 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
10899 * xdisp.c (row_hash): New function, body extracted from
10900 compute_line_metrics.
10901 (compute_line_metrics): Call row_hash, instead of computing the
10904 * dispnew.c (verify_row_hash): Call row_hash for computing the
10905 hash code of a row, instead of duplicating code from xdisp.c.
10907 * dispextern.h (row_hash): Add prototype.
10909 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>

10945 2011-11-14 Eli Zaretskii <eliz@gnu.org>
10947 * xdisp.c (display_line): Move the call to
10948 highlight_trailing_whitespace before the call to
10949 compute_line_metrics, since the latter needs to see the final
10950 faces of all the glyphs to compute ROW's hash value.
10951 Fixes assertion violations in row_equal_p. (Bug#10035)
10953 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
10955 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,
10956 just return (bug#10044).
10958 2011-11-12 Eli Zaretskii <eliz@gnu.org>
10960 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
10961 with user-defined heap size. Bump the default size of the temacs

10965 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
10966 current_matrix and desired_matrix. (Bug#9990)
10967 (verify_row_hash) [XASSERTS]: New function.

11014 Avoid some portability problems by eschewing 'extern inline' functions.
11015 The trivial performance wins aren't worth the portability hassles; see
11016 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
11018 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

11084 * xmenu.c (cleanup_widget_value_tree): New function.
11085 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of

11092 (window_box_width, window_box_left, window_box_left_offset)
11093 (window_box_right, window_box_right_offset): Declare extern.
11094 Otherwise, these inline functions do not conform to C99 and
11095 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
11096 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
11097 * intervals.c (adjust_intervals_for_insertion)

11100 (static_offset_intervals): Remove.
11101 (offset_intervals): Rewrite using the old contents of
11102 static_offset_intervals. The old version didn't conform to C99
11103 because an extern inline function contained a reference to an
11104 identifier with static linkage.

11157 (unwind_create_frame): New function (Bug#9943).
11158 (Fx_create_frame): Restructure code to be more similar to the one in
11159 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).

11216 * gtkutil.c (xg_make_tool_item): Add callbacks if one of wimage or
11217 label is not null (Bug#9951).
11218 (xg_tool_item_stale_p): Handle the fact that wimage and/or wlbl
11221 2011-11-04 Eli Zaretskii <eliz@gnu.org>
11223 * window.c (Fwindow_body_size): Mention in the doc string that the
11224 return value is in frame's canonical units. (Bug#9949)
11226 2011-11-03 Eli Zaretskii <eliz@gnu.org>
11228 * xdisp.c (note_mouse_highlight): Initialize `area'. (Bug#9947)
11230 * w32fns.c (unwind_create_frame): If needed, free the glyph
11231 matrices of the partially constructed frame. (Bug#9943)
11232 * xfns.c (unwind_create_frame): Likewise.
11234 2011-11-01 Eli Zaretskii <eliz@gnu.org>
11236 * xdisp.c (mouse_face_from_buffer_pos): Fix a typo in a comment.
11237 Don't stop backward scan on the continuation glyph, even though
11238 its CHARPOS is positive.
11239 (mouse_face_from_buffer_pos, note_mouse_highlight):
11240 Rename cover_string to disp_string.
11242 2011-11-01 Martin Rudalics <rudalics@gmx.at>
11244 * window.c (temp_output_buffer_show): Don't use
11245 Vtemp_buffer_show_specifiers.
11246 (Vtemp_buffer_show_specifiers): Remove unused variable.
11248 2011-10-30 Eli Zaretskii <eliz@gnu.org>
11250 * xdisp.c (try_cursor_movement): Make sure ROW isn't decremented
11251 past the beginning of the current glyph matrix.
11253 2011-10-30 Adam Sjøgren <asjo@koldfront.dk> (tiny change)
11255 * xterm.c: Include X11/Xproto.h if HAVE_GTK3.
11256 (x_error_handler): Ignore BadMatch for X_SetInputFocus for
11257 HAVE_GTK3 (Bug#9869).
11259 * gtkutil.c (xg_win_to_widget, xg_event_is_for_menubar): Initialize
11260 type to GDK_NOTHING so valgrind does not complain (Bug#9901).
11262 * xterm.h (x_display_info): Add Xatom_net_wm_state_hidden (Bug#9893).
11264 * xterm.c: Declare x_handle_net_wm_state to return int.
11265 (handle_one_xevent): Check if we are iconified but don't have
11266 _NET_WM_STATE_HIDDEN. If do, treat as deiconify (Bug#9893).
11267 (get_current_wm_state): Return non-zero if not hidden,
11268 check for _NET_WM_STATE_HIDDEN (Bug#9893).

11270 (x_handle_net_wm_state): Return what get_current_wm_state returns.
11271 (x_term_init): Initialize dpyinfo->Xatom_net_wm_state_hidden.
11273 2011-10-29 Paul Eggert <eggert@cs.ucla.edu>
11275 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
11276 so that this new function doesn't get optimized away by a
11277 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
11279 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
11281 * frame.h (MOUSE_HL_INFO): Remove excess parens.
11283 2011-10-29 Eli Zaretskii <eliz@gnu.org>
11285 Fix the `xbytecode' command.
11286 * .gdbinit (xprintbytestr): New command.
11287 (xwhichsymbols): Rename from `which'; all callers changed.
11288 (xbytecode): Print the byte-code string as well.
11290 2011-10-29 Kim Storm <storm@cua.dk>
11292 * alloc.c (which_symbols): New function.
11294 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
11296 * minibuf.c (read_minibuf_noninteractive): Allow reading empty
11299 2011-10-29 Glenn Morris <rgm@gnu.org>
11301 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
11302 Not clear what it was for, and it causes various bugs. (Bug#9839)
11304 2011-10-28 Eli Zaretskii <eliz@gnu.org>
11306 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
11307 possible random value that matches one of those tested as
11308 condition to clear the mouse face.
11310 2011-10-28 Chong Yidong <cyd@gnu.org>
11312 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.
11314 2011-10-28 Dan Nicolaescu <dann@ics.uci.edu>
11316 * window.c (make_window): Initialize phys_cursor_on_p.
11318 2011-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
11320 * lisp.h (struct Lisp_Symbol): Update comments.
11322 2011-10-28 Juanma Barranquero <lekktu@gmail.com>
11324 * w32font.c (w32_load_unicows_or_gdi32): Add missing return.
11326 2011-10-28 Eli Zaretskii <eliz@gnu.org>
11328 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
11329 <oslsachem@gmail.com> for helping to debug this.
11331 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
11332 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
11333 (g_b_init_get_glyph_outline_w): New static variables.
11334 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
11335 (GetGlyphOutlineW_Proc): New typedefs.
11336 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
11337 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
11339 (w32font_open_internal, compute_metrics):
11340 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
11341 instead of calling the "wide" APIs directly.
11343 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
11345 * w32.h (syms_of_w32font): Add prototype.
11347 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
11349 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
11350 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
11351 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
11352 (Fmove_to_window_line): Doc fix.
11354 2011-10-27 Chong Yidong <cyd@gnu.org>
11356 * process.c (make_process): Set gnutls_state to NULL.
11358 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
11359 non-NULL, regardless of GNUTLS_INITSTAGE.
11360 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
11361 an error. Set process slots as soon as we allocate them.
11363 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
11365 2011-10-27 Chong Yidong <cyd@gnu.org>
11367 * gnutls.c (emacs_gnutls_deinit): New function.
11368 Deallocate credentials structures as well as calling gnutls_deinit.
11369 (Fgnutls_deinit, Fgnutls_boot): Use it.
11371 * process.c (make_process): Initialize GnuTLS credentials to NULL.
11372 (deactivate_process): Call emacs_gnutls_deinit.
11374 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
11376 * image.c (x_create_x_image_and_pixmap):
11377 * w32.c (sys_rename, w32_delayed_load):
11378 * w32font.c (fill_in_logfont):
11379 * w32reg.c (x_get_string_resource): Silence compiler warnings.
11381 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
11383 * w32fns.c (w32_default_color_map): New function,
11384 extracted from Fw32_default_color_map.
11385 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
11387 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
11389 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
11391 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
11393 * keyboard.c (test_undefined): New function (bug#9751).
11394 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
11396 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
11398 * sysdep.c (init_sys_modes): Fix the check for the controlling
11399 terminal (Bug#6649).
11401 2011-10-20 Eli Zaretskii <eliz@gnu.org>
11403 * dispextern.h (struct bidi_it): New member next_en_type.
11405 * bidi.c (bidi_line_init): Initialize the next_en_type member.
11406 (bidi_resolve_explicit_1): When next_en_pos is valid for the
11407 current character, check also for next_en_type being WEAK_EN.
11408 (bidi_resolve_weak): Don't enter the expensive loop if the current
11409 position is before next_en_pos. Record the bidi type of the first
11410 non-ET, non-BN character we find, in addition to its position.
11411 (bidi_level_of_next_char): Invalidate next_en_type when
11412 next_en_pos is over-stepped.
11414 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
11416 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
11417 * editfns.c: Rewrite current-time-zone so that it invokes
11418 the equivalent of (format-time-string "%Z") to get the time zone name.
11419 This fixes a bug when the time zone name contains characters that
11420 need converting from the system time locale to Emacs internal format.
11421 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
11422 that patch fixed format-time-string to do the conversion, but
11423 I forgot to fix current-time-zone.
11424 (format_time_string): New function, containing most of
11425 what Fformat_time_string used to contain.
11426 (Fformat_time_string): Rewrite in terms of format_time_string.
11427 This doesn't change this function's behavior.
11428 (current-time-zone): Rewrite to use format_time_string.
11429 This fixes the bug reported by Michael Schierl in
11430 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
11431 Jason Rumney's 2007-06-07 change worked around this bug, but
11433 * systime.h (tzname, timezone): Remove no-longer-used declarations.
11435 2011-10-19 Eli Zaretskii <eliz@gnu.org>
11437 * xdisp.c (start_display): If the character at POS is displayed
11438 via a display vector, reset IT->current.dpvec_index to zero.
11439 (try_window_reusing_current_matrix): If a line ends in a display
11440 vector or the next line starts in a display vector, continue
11441 redrawing the window even though the character position of
11442 start_row was reached.
11445 2011-10-18 Chong Yidong <cyd@gnu.org>
11447 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
11448 with nobreak-char-display too.
11450 2011-10-18 Eli Zaretskii <eliz@gnu.org>
11452 Fix part 3 of bug#9771.
11453 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
11454 (bidi_resolve_neutral): Don't enter the expensive loop looking for
11455 non-neutral characters if the current character is a paragraph
11456 separator (a.k.a. Newline). This avoids running the same
11457 expensive loop twice, once when we consume the preceding newline
11458 and the other time when the line actually needs to be displayed.
11459 Avoid the loop when we see neutrals on the base embedding level
11460 following a character whose directionality is the same as the
11461 paragraph's. This avoids running the expensive loop when a line
11462 ends in a long sequence of neutrals, like control characters.
11463 Add assertion against STRONG_AL type. Slightly rearrange code
11464 that determines the type of a neutral given the first non-neutral
11466 (bidi_level_of_next_char): Set next_en_pos to zero when
11467 invalidating its info.
11469 2011-10-17 Eli Zaretskii <eliz@gnu.org>
11471 * xdisp.c (push_display_prop): Determine whether to record string
11472 or buffer position by IT->string, not by IT->method. Allow
11473 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
11474 (move_it_vertically_backward): Don't look for character position
11475 immediately after the newline when in a continuation line.
11478 2011-10-15 Martin Rudalics <rudalics@gmx.at>
11480 * window.c (coordinates_in_window): Rewrite and delabelize
11481 vertical border check. (Bug#5357) (Bug#9618)
11483 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
11485 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
11486 errors in XSetWindowBorder (bug#9310).
11488 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
11490 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
11491 avoid crash when xmalloc overrun checking is enabled.
11493 2011-10-13 Eli Zaretskii <eliz@gnu.org>
11495 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
11496 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
11497 cursor motion with <left> and <right> arrow keys.
11499 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
11500 some callers set that themselves.
11502 2011-10-12 Eli Zaretskii <eliz@gnu.org>
11504 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
11505 display string and the previous row comes from the same string and
11506 is empty. (Bug#9739) (Bug#9738)
11508 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
11510 * doc.c (get_doc_string): Encode file name (bug#9735).
11512 2011-10-12 Eli Zaretskii <eliz@gnu.org>
11514 * bidi.c (bidi_level_of_next_char):
11515 * xdisp.c (get_visually_first_element): Remove old incorrect
11516 comments regarding the Unicode Line Separator character.
11518 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
11520 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
11522 * alloc.c (Fgc_status): Do not access beyond zombies array
11523 boundary if nzombies > MAX_ZOMBIES.
11524 * alloc.c (dump_zombies): Add missing format specifier.
11526 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
11528 * xdisp.c (set_cursor_from_row): Simplify conditionals,
11529 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
11531 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
11532 Some packages use them to denote characters with modifiers.
11534 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
11536 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
11537 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
11538 matching a pp-number. Rename parameter var to var1.
11540 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
11542 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
11544 2011-10-08 Glenn Morris <rgm@gnu.org>
11546 * callint.c (Fcall_interactively): Give a more explicit error for the
11547 'c' case with a non-character input. (Bug#8479)
11549 2011-10-08 Eli Zaretskii <eliz@gnu.org>
11551 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
11553 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
11554 lines that are hscrolled on the left.
11556 * dispnew.c (buffer_posn_from_coords): Account for a possible
11557 presence of header-line. (Bug#4426)
11559 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
11561 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
11562 Don't advertise functionality which we discourage or doesn't work.
11564 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
11566 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
11567 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
11568 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
11569 this makes Emacs dump core during garbage collection on rare
11570 occasions. sizeof is obviously inferior to offsetof here, so
11571 stick with offsetof.
11572 (GC_POINTER_ALIGNMENT): New macro.
11573 (mark_memory): Omit 3rd (offset) arg; caller changed.
11574 Don't assume EMACS_INT alignment is the same as pointer alignment.
11576 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
11578 * keyboard.c (read_key_sequence_remapped): New var.
11579 (read_key_sequence): Compute remapping in the right buffer.
11580 (command_loop_1): Use read_key_sequence's remapping directly.
11582 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
11584 * dired.c (file_name_completion): Don't expand file name.
11585 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
11586 before checking file name handler.
11588 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
11589 they've been requested explicitly (bug#9591).
11591 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
11593 * keymap.c (Fsingle_key_description): Use make_specified_string
11594 instead of build_string to build string from push_key_description.
11597 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
11599 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
11600 This fixes a Y2038 bug on 64-bit hosts.
11601 * buffer.c (reset_buffer):
11602 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
11603 (Fclear_buffer_auto_save_failure):
11604 Use 0, not -1, to represent an unset failure time, since time_t
11605 might not be signed.
11607 Remove dependency on glibc malloc internals.
11608 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11609 Move back here from lisp.h, but with their new implementations.
11610 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
11611 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
11612 * charset.c (charset_table_init): New static var.
11613 (syms_of_charset): Use it instead of xmalloc. This removes a
11614 dependency on glibc malloc internals. See Eli Zaretskii's comment in
11615 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
11616 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11617 Move back to alloc.c.
11618 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
11619 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
11621 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
11623 * nsterm.m (windowDidResize): Call x_set_window_size only when
11624 ns_in_resize is true. Otherwise set pixelwidth/height and
11625 call change_frame_size (Bug#9628).
11627 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
11629 Port --enable-checking=all to Fedora 14 x86-64.
11630 * charset.c (syms_of_charset): Also account for glibc malloc's
11631 internal overhead when calculating the initial malloc maximum.
11633 Port --enable-checking=all to Fedora 14 x86.
11634 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11636 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
11637 (overrun_check_realloc, overrun_check_free):
11638 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
11639 That way, xmalloc returns a properly-aligned pointer even if
11640 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
11641 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
11642 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
11643 into account when calculating the initial malloc maximum.
11644 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11645 Move here from alloc.c, so that charset.c can use it too.
11646 Properly align; the old code wasn't right for common 32-bit hosts
11647 when configured with --enable-checking=all.
11648 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
11649 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
11651 2011-09-29 Eli Zaretskii <eliz@gnu.org>
11653 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
11656 2011-09-28 Eli Zaretskii <eliz@gnu.org>
11658 * xdisp.c (compute_display_string_end): If there's no display
11659 string at CHARPOS, return -1.
11661 * bidi.c (bidi_fetch_char): When compute_display_string_end
11662 returns a negative value, treat the character as a normal
11663 character not covered by a display string. (Bug#9624)
11665 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
11667 * lread.c (Fread_from_string): Fix typo in docstring.
11669 2011-09-27 Eli Zaretskii <eliz@gnu.org>
11671 * xdisp.c (handle_invisible_prop): If invisible text ends on a
11672 newline, reseat the iterator instead of bidi-iterating there one
11673 character at a time. (Bug#9610)
11674 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
11675 TO_CHARPOS if the bidi iterator is at base embedding level.
11677 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
11679 * lread.c (readevalloop): Use correct code for NBSP.
11680 (read1): Likewise. (Bug#9608)
11682 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
11684 * dbusbind.c (Fdbus_register_signal): When service is not

11687 2011-09-25 Glenn Morris <rgm@gnu.org>
11689 * buffer.c (truncate-lines): Doc fix.
11691 2011-09-24 Chong Yidong <cyd@stupidchicken.com>

11709 Default value is now t. Doc fix.
11711 * indent.c (Fvertical_motion): Compute and apply the overshoot
11712 logic when moving up, not only when moving down. Fix the
11713 confusing name and values of the it_overshoot_expected variable;
11714 logic changes accordingly. (Bug#9254) (Bug#9549)
11716 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
11717 CHARPOS is covered by a display string which includes newlines.
11718 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
11719 is covered by a display string with embedded newlines.
11721 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
11723 * dbusbind.c (Fdbus_register_signal): Add match rule to
11724 Vdbus_registered_objects_table. (Bug#9581)

11728 2011-09-24 Jim Meyering <meyering@redhat.com>
11730 do not ignore write error for any output size
11731 The previous change was incomplete.
11732 While it makes emacs --batch detect the vast majority of stdout
11733 write failures, errors were still ignored whenever the output size is
11734 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
11735 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
11736 && echo FAIL: ignored write error
11737 FAIL: ignored write error
11738 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
11739 && echo FAIL: ignored write error
11740 FAIL: ignored write error
11741 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
11743 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
11745 * emacs.c (Fkill_emacs): In noninteractive mode exit
11746 non-successfully if a write error occurred on stdout. (Bug#9574)
11748 2011-09-21 Eli Zaretskii <eliz@gnu.org>
11750 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
11753 * dispextern.h (struct it): Update the comment documenting what
11756 2011-09-20 Eli Zaretskii <eliz@gnu.org>
11758 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
11759 a display string, extend search for cursor position to end of row.
11760 (find_row_edges): If the row ends in a newline from a display
11761 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
11762 Handle the case of a display string with multiple newlines.
11763 (Fcurrent_bidi_paragraph_direction): Fix search for previous
11764 non-empty line. Fixes confusing cursor motion with arrow keys at
11765 the beginning of a line that starts with whitespace.
11767 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
11769 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
11772 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
11774 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
11775 boolean (Bug#9154).
11777 2011-09-18 Eli Zaretskii <eliz@gnu.org>
11779 * xdisp.c (display_line): Record maximum and minimum buffer
11780 positions even if no glyphs were produced (e.g., by a zero-width
11781 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
11782 buffer positions that will be removed from the glyph row because
11784 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
11785 column is beyond frame width: don't subtract 1 "pixel" when
11786 computing width of the stretch.
11787 (reseat_at_next_visible_line_start): Undo the change made on
11788 2011-09-17 that saved paragraph information and restored it after
11789 the call to `reseat'. (Bug#9545)
11791 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11793 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
11794 and turn window cursor on if cleared (Bug#9415).
11796 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
11798 * search.c (boyer_moore): Take unibyte characters from pattern
11799 literally. (Bug#9458)

11812 (Finsert_file_contents): Save and restore errno,
11813 so that report_file_error outputs the correct diagnostic.

11816 2011-09-18 Eli Zaretskii <eliz@gnu.org>
11818 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
11820 2011-09-17 Eli Zaretskii <eliz@gnu.org>
11822 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
11823 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
11825 2011-09-17 Eli Zaretskii <eliz@gnu.org>
11827 * xdisp.c (reseat_at_next_visible_line_start): Keep information
11828 about the current paragraph and restore it after the call to reseat.
11830 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
11831 (bidi_find_paragraph_start): Search back for paragraph beginning
11832 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
11833 (bidi_move_to_visually_next): Only trigger paragraph-related
11834 computations when the last character is a newline or at EOB, not
11835 just any NEUTRAL_B. (Bug#9470)
11837 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
11838 truncated lines if point is covered by a display string. (Bug#9524)
11840 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
11842 * xselect.c: Relax test for outgoing X longs (Bug#9498).
11843 (cons_to_x_long): New function.
11844 (lisp_data_to_selection_data): Use it. Correct the test for
11845 short-versus-long data; it was negated. Break out of vector
11846 loop, for efficiency, when a long datum is discovered.
11848 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
11850 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
11852 2011-09-16 Eli Zaretskii <eliz@gnu.org>
11854 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
11855 GCC PR/17406) by declaring this function with external scope.
11857 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
11859 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
11860 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
11862 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
11864 * editfns.c (Fformat): Correctly handle text properties on "%%".

11874 of TAB characters in a composition.
11876 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
11878 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
11879 This occurs when processing a multibyte format.
11880 Problem reported by Wolfgang Jenker.
11882 2011-09-15 Johan Bockgård <bojohan@gnu.org>
11884 * xdisp.c (try_cursor_movement): Only check for exact match if
11885 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
11887 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
11889 Remove unused external symbols.
11890 * dispextern.h (calc_pixel_width_or_height): Remove decl.
11891 * xdisp.c (calc_pixel_width_or_height): Now static.
11892 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
11893 * indent.c (check_display_width):
11894 * w32term.c: Fix comment to match code.
11895 * xterm.c, xterm.h (x_catching_errors): Remove.
11897 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
11899 * xselect.c: Use signed conversions more consistently (Bug#9498).
11900 (selection_data_to_lisp_data): Assume incoming selection data are
11901 signed integers, not unsigned. This is to be consistent with
11902 outgoing selection data, which was modified to use signed integers
11903 in as part of the fix to Bug#9196 in response to Jan D.'s comment
11904 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
11905 expects long, not unsigned long.
11907 2011-09-14 Eli Zaretskii <eliz@gnu.org>
11909 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
11910 computation of loop end. Reported by Johan Bockgård
11913 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
11915 * frame.c (Fother_visible_frames_p): Function deleted.
11917 2011-09-12 Eli Zaretskii <eliz@gnu.org>
11919 * indent.c (compute_motion): Process display vector front to back
11920 rather than the other way around. (Bug#2496)
11922 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
11924 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
11926 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
11928 * minibuf.c (Fread_from_minibuffer): Doc fix.
11930 2011-09-11 Eli Zaretskii <eliz@gnu.org>
11932 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
11933 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
11935 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
11937 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
11938 value for non-existent files.
11940 2011-09-11 Eli Zaretskii <eliz@gnu.org>
11942 * fileio.c (Finsert_file_contents): If the file cannot be opened,
11943 set its "size" to -1. This will set the modtime_size field of
11944 the corresponding buffer to -1, which is what
11945 verify-visited-file-modtime expects for files that do not exist.
11948 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
11950 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
11952 * lisp.h: ... from here. push_key_description is no longer
11953 defined in keyboard.c, so its declaration should not be in
11954 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
11955 logically belongs with push_key_description.
11957 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
11959 * buffer.h: Include <sys/types.h> instead of <time.h>.
11960 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
11961 Problem reported by Herbert J. Skuhra.
11963 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
11965 * xml.c (parse_region): Make the parsing work for
11966 non-comment-starting XML files again (bug#9144).
11968 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
11970 * image.c (gif_load): Fix calculation of bottom and right corner.
11973 2011-09-10 Eli Zaretskii <eliz@gnu.org>
11975 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
11976 redisplay in small windows.
11978 2011-09-09 Eli Zaretskii <eliz@gnu.org>
11980 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
11982 2011-09-08 Martin Rudalics <rudalics@gmx.at>
11984 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
11985 Operate on live windows only.
11987 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
11989 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
11991 2011-09-07 Eli Zaretskii <eliz@gnu.org>
11993 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
11994 only under bidi iteration.
11996 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
11998 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
12000 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
12002 isnan: Fix porting problem to Solaris 10 with bundled gcc.
12003 Without this fix, the command to link temacs failed due to an
12004 undefined symbol __builtin_isnan. This is because
12005 /usr/include/iso/math_c99.h #defines isnan(x) to
12006 __builtin_isnan(x), but the bundled gcc, which identifies itself
12007 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
12009 * floatfns.c (isnan): #undef, and then #define to a clone of
12011 (Fisnan): Always define, since it's always available now.
12012 (syms_of_floatfns): Always define isnan at the Lisp level.
12014 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
12016 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
12018 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
12020 * fileio.c: Fix bugs with large file offsets (Bug#9428).
12021 The previous code assumed that file offsets (off_t values) fit in
12022 EMACS_INT variables, which is not true on typical 32-bit hosts.
12023 The code messed up by falsely reporting buffer overflow in cases
12024 such as (insert-file-contents "big" nil 1 2) into an empty buffer
12025 when "big" contains more than 2**29 bytes, even though this
12026 inserts just one byte and does not overflow the buffer.
12027 (Finsert_file_contents): Store file offsets as off_t
12028 values, not as EMACS_INT values. Check for overflow when
12029 converting between EMACS_INT and off_t. When checking for
12030 buffer overflow or for overlap, take the offsets into account.
12031 Don't use EMACS_INT for small values where int suffices.
12032 When checking for overlap, fix a typo: ZV was used where
12033 ZV_BYTE was intended.
12034 (Fwrite_region): Don't assume off_t fits into 'long'.
12035 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
12037 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
12039 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
12041 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
12043 sprintf-related integer and memory overflow issues (Bug#9412).
12045 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
12046 (esprintf, exprintf, evxprintf): New functions.
12047 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
12048 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
12049 (modify_event_symbol): Do not assume that the length of
12050 name_alist_or_stem is safe to alloca and fits in int.
12051 (Fexecute_extended_command): Likewise for function name and binding.
12052 (Frecursion_depth): Wrap around reliably on integer overflow.
12053 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
12054 since some callers pass EMACS_INT values.
12055 (Fsingle_key_description): Don't crash if symbol name contains more
12056 than MAX_ALLOCA bytes.
12057 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
12058 (get_minibuffer): Arg is now EMACS_INT, not int.
12059 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
12060 (esprintf, exprintf, evxprintf): New decls.
12061 * window.h (command_loop_level, minibuf_level): Reflect API changes.
12063 * dbusbind.c (signature_cat): New function.
12064 (xd_signature, Fdbus_register_signal):
12065 Do not overrun buffer; instead, report string overflow.
12067 * dispnew.c (add_window_display_history): Don't overrun buffer.
12068 Truncate instead; this is OK since it's just a log.
12070 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
12071 even if the time zone offset is outlandishly large.
12072 Don't mishandle offset == INT_MIN.
12074 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
12075 when creating daemon; the previous buffer-overflow check was incorrect.
12077 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
12078 which has the guts of the old verror function.
12080 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
12081 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
12083 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
12084 (font_unparse_xlfd): Don't blindly alloca long strings.
12085 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
12086 fits in int, when using sprintf. Use single snprintf to count
12087 length of string rather than counting it via multiple sprintfs;
12088 that's simpler and more reliable.
12089 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
12090 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
12091 sprintf, in case result does not fit in int.
12093 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
12094 (fontset_from_font): Print it.
12096 * frame.c (tty_frame_count): Now printmax_t, not int.
12097 (make_terminal_frame, set_term_frame_name): Print it.
12098 (x_report_frame_params): In X, window IDs are unsigned long,
12099 not signed long, so print them as unsigned.
12100 (validate_x_resource_name): Check for implausibly long names,
12101 and don't assume name length fits in 'int'.
12102 (x_get_resource_string): Don't blindly alloca invocation name;
12103 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
12106 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
12107 (xg_check_special_colors, xg_set_geometry):
12108 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
12110 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
12111 Use esprintf, not sprintf, in case result does not fit in int.
12113 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
12114 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
12115 it as a large positive number.
12116 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
12117 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
12119 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
12120 in case result does not fit in int.
12122 * print.c (float_to_string): Detect width overflow more reliably.
12123 (print_object): Make sprintf buffer a bit bigger, to avoid potential
12124 buffer overrun. Don't assume list length fits in 'int'. Treat
12125 print length of 0 as 0, not as infinity; to be consistent with other
12126 uses of print length in this function. Don't overflow print length
12127 index. Don't assume hash table size fits in 'long', or that
12128 vectorlike size fits in 'unsigned long'.
12130 * process.c (make_process): Use printmax_t, not int, to format
12131 process-name gensyms.
12133 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
12135 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
12136 to avoid potential buffer overrun.
12138 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
12139 if X resource line is longer than 512 bytes.
12141 * xfns.c (x_window): Make sprintf buffer a bit bigger
12142 to avoid potential buffer overrun.
12144 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
12146 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
12148 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
12150 Integer overflow fixes for scrolling, etc.
12151 Without these, Emacs silently mishandles large integers sometimes.
12152 For example, "C-u 4294967297 M-x recenter" was treated as if
12153 it were "C-u 1 M-x recenter" on a typical 64-bit host.
12155 * xdisp.c (try_window_id): Check Emacs fixnum range before
12156 converting to 'int'.
12158 * window.c (window_scroll_line_based, Frecenter):
12159 Check that an Emacs fixnum is in range before assigning it to 'int'.
12160 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
12161 values converted from Emacs fixnums.
12162 (Frecenter): Don't wrap around a line count if it is out of 'int'
12163 range; instead, treat it as an extreme value.
12164 (Fset_window_configuration, compare_window_configurations):
12165 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
12167 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
12168 that can exceed INT_MAX. Check that EMACS_INT value is in range
12169 before assigning it to the (possibly-narrower) index.
12170 (match_limit): Don't assume that a fixnum can fit in 'int'.
12172 * print.c (print_object): Use ptrdiff_t, not int, for index that can
12175 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
12176 (Fvertical_motion): Don't wrap around LINES values that don't fit
12177 in 'int'. Instead, treat them as extreme values. This is good
12178 enough for windows, which can't have more than INT_MAX lines anyway.
12180 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
12182 * Require libxml/parser.h to avoid compilation warning.
12184 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
12186 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
12187 since this reportedly can destroy thread storage.
12189 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
12191 * syntax.c (find_defun_start): Update all cache variables if
12192 exiting early (Bug#9401).
12194 2011-08-30 Eli Zaretskii <eliz@gnu.org>
12196 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
12198 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
12199 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
12200 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
12202 * term.c (tty_append_glyph): New function.
12203 (produce_stretch_glyph): Static function and its prototype deleted.
12205 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
12208 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
12210 * image.c (parse_image_spec): Check for nonnegative, not for positive,
12211 when checking :margin (Bug#9390).
12212 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
12213 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
12214 so that the name doesn't mislead. All uses changed.
12216 2011-08-28 Johan Bockgård <bojohan@gnu.org>
12218 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
12221 2011-08-27 Eli Zaretskii <eliz@gnu.org>
12223 * xdisp.c (move_it_to): Don't bail out early when reaching
12224 position beyond to_charpos, if we are scanning backwards.
12225 (move_it_vertically_backward): When DY == 0, make sure we get to
12226 the first character in the line after the newline.
12228 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
12230 * ccl.c: Improve and simplify overflow checking (Bug#9196).
12231 (ccl_driver): Do not generate an out-of-range pointer.
12232 (Fccl_execute_on_string): Remove unnecessary check for
12233 integer overflow, noted by Stefan Monnier in
12234 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
12235 Remove a FIXME that didn't need fixing.
12236 Simplify the newly-introduced buffer reallocation code.
12238 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
12240 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
12242 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
12244 Integer and memory overflow issues (Bug#9196).
12246 * doc.c (get_doc_string): Rework so that
12247 get_doc_string_buffer_size is the actual buffer size, rather than
12248 being 1 less than the actual buffer size; this makes xpalloc more
12251 * image.c (x_allocate_bitmap_record, cache_image):
12252 * xselect.c (Fx_register_dnd_atom):
12253 Simplify previous changes by using xpalloc.
12255 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
12256 since either will do and ptrdiff_t is convenient with xpalloc.
12258 * charset.c (charset_table_size)
12259 (struct charset_sort_data.priority): Now ptrdiff_t.
12260 (charset_compare): Don't overflow if priorities differ greatly.
12261 (Fsort_charsets): Don't assume list length fits in int.
12262 Check for size-calculation overflow when allocating sort data.
12263 (syms_of_charset): Allocate an initial charset table that is
12264 just under 64 KiB, to avoid problems with glibc malloc and mmap.
12266 * cmds.c (internal_self_insert): Check for size-calculation overflow.
12268 * composite.h (struct composition.glyph_len): Now int, not unsigned.
12269 The actual value is always <= INT_MAX, and leaving it unsigned made
12270 overflow checking harder.
12272 * dispextern.h (struct glyph_matrix.rows_allocated)
12273 (struct face_cache.size): Now ptrdiff_t, for convenience in use
12274 with xpalloc. The values are still always <= INT_MAX.
12276 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
12278 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
12279 (SAFE_NALLOCA): New macro.
12281 * region-cache.c (struct boundary.pos, find_cache_boundary)
12282 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
12283 (set_cache_region, invalidate_region_cache)
12284 (revalidate_region_cache, know_region_cache, region_cache_forward)
12285 (region_cache_backward, pp_cache):
12286 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
12287 so that ptrdiff_t * can be passed to xpalloc.
12288 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
12289 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
12290 (pp_cache): Don't assume cache_len fits in int.
12291 * region-cache.h: Adjust extern decls to match.
12293 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
12294 EMACS_INT, since either will do, for xpalloc.
12296 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
12297 (xnmalloc, xnrealloc, xpalloc): New functions.
12299 * bidi.c (bidi_shelve_header_size): New constant.
12300 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
12301 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
12303 * bidi.c (bidi_cache_shrink):
12304 * buffer.c (overlays_at, overlays_in, record_overlay_string)
12306 Don't update size of array until after memory allocation succeeds,
12307 because xmalloc/xrealloc may not return.
12308 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
12309 now that we have proper integer overflow checking.
12310 (record_overlay_string, overlay_strings): Catch overflows when
12311 calculating size of overlay_str_buf.
12313 * callproc.c (Fcall_process): Check for size overflow when
12314 calculating size of args2.
12315 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
12316 Normally we prefer signed values, but sticking with ptrdiff_t would
12317 require adding more-complicated checks.
12319 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
12320 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
12321 Redo buffer-overflow calculations to avoid integer overflow.
12322 Add a FIXME comment where memory seems to be over-allocated.
12324 * character.c (Fstring): Check for size-calculation overflow.
12326 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
12327 unnecessary integer overflow. Check for size overflow.
12328 (encode_coding_object): Don't update size until xmalloc succeeds.
12330 * composite.c (get_composition_id): Check for overflow in glyph
12331 length calculations.
12333 Integer and memory overflow fixes for display code.
12334 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
12335 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
12336 (scrolling_window): Check for overflow in size calculations.
12337 (line_draw_cost, realloc_glyph_pool, add_row_entry):
12338 Don't assume glyph table len fits in int.

12340 (row_table_size): Now ptrdiff_t, not int.
12341 (scrolling_window): Avoid overflow in size calculations.
12342 Don't update size until allocation succeeds.
12343 * fns.c (concat): Check for overflow in size calculations.
12344 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
12345 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.

12348 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
12349 (get_doc_string): Check for size calculation overflow.
12350 Don't update size until allocation succeeds.
12351 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
12352 EMACS_INT, where ptrdiff_t will do.
12353 (Fsubstitute_command_keys): Check for string overflow.
12355 * editfns.c (set_time_zone_rule): Don't assume environment length
12357 (message_length): Now ptrdiff_t, not int.
12358 (Fmessage_box): Don't update size until allocation succeeds.
12359 Don't assume message length fits in int.
12360 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
12362 * emacs.c (main): Do not reallocate argv, since there is a null at
12363 the end that can be overwritten, and this way there's no need to
12364 worry about size-calculation overflow.
12365 (sort_args): Check for size-calculation overflow.
12367 * eval.c (init_eval_once, grow_specpdl): Don't update size until
12369 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
12371 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
12372 (x_set_scroll_bar_width, x_figure_window_size):
12373 Check for integer overflow.
12374 (x_set_alpha): Do not assume XINT fits in int.
12376 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
12377 This is for the members text_lines, text_cols, total_lines, total_cols,
12378 where the system imposes an 'int' limit.
12380 * fringe.c (Fdefine_fringe_bitmap):
12381 Don't update size until alloc works.
12383 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
12384 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
12386 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
12387 Check for size-calculation overflow.
12388 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
12389 do, as we prefer signed integers.
12390 (id_to_widget.max_size, id_to_widget.used)
12391 (xg_store_widget_in_map, xg_remove_widget_from_map)
12392 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
12393 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
12394 Use and return ptrdiff_t, not int.
12395 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
12396 * gtkutil.h: Change prototypes to match the above.
12398 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
12399 are duplicate now that they've been promoted to lisp.h.
12400 (x_allocate_bitmap_record, x_alloc_image_color)
12401 (make_image_cache, cache_image, xpm_load):
12402 Don't update size until alloc is done.
12403 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
12405 Check for size calculation overflow.
12406 (ct_colors_allocated_max): New constant.
12407 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid
12410 * keyboard.c (read_char, menu_bar_items, tool_bar_items)
12411 (read_char_x_menu_prompt, read_char_minibuf_menu_width)
12412 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
12413 Use ptrdiff_t, not int, to count maps.
12414 (read_char_minibuf_menu_prompt): Check for overflow in size
12415 calculations. Don't update size until allocation succeeds.
12416 Redo calculations to avoid overflow.
12417 * keyboard.h: Change prototypes to match the above.
12419 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
12421 (current_minor_maps): Check for size calculation overflow.
12422 * keymap.h: Change prototypes to match the above.
12424 * lread.c (read1, init_obarray): Don't update size until alloc done.
12426 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.
12427 (store_kbd_macro_char): Reorder multiplicands to avoid overflow.
12429 * nsterm.h (struct ns_color_table.size, struct ns_color_table.avail):
12430 Now ptrdiff_t, not int.
12431 * nsterm.m (ns_index_color): Use ptrdiff_t, not int, for table indexes.

12443 (Fset_match_data): Don't assume list lengths fit in 'int'.
12445 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
12446 for command line length. Do not attempt to address one before the
12447 beginning of an array, as that's not portable.
12449 * term.c (max_frame_lines): Remove; unused.
12450 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
12452 (encode_terminal_code, calculate_costs): Check for size
12453 calculation overflow.

12456 done. Redo calculations to avoid overflow.
12457 (calculate_costs): Don't bother calling xmalloc when xrealloc will do.
12459 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
12460 subtracting pointers.
12461 (gobble_line): Check for overflow more carefully. Don't update size
12464 * tparam.c (tparam1): Use ptrdiff_t, not int, for sizes.

12475 Use ptrdiff_t, not int, for sizes.
12476 (Finternal_make_lisp_face, cache_face):
12477 Check for size calculation overflow.
12478 (cache_face): Treat size calculation overflows as if they were
12479 memory exhaustion (the usual treatment), rather than aborting.
12481 * xfns.c (x_encode_text, x_set_name_internal)
12482 (Fx_change_window_property): Use ptrdiff_t, not int, to count
12483 sizes, since they can exceed INT_MAX in size. Check for size
12484 calculation overflow.
12486 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
12487 (xg_select): Check for size calculation overflow.
12488 Don't update size until alloc done.
12490 * xrdb.c (get_environ_db): Don't assume path length fits in int,
12491 as sprintf is limited to int lengths.
12493 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
12494 (X_LONG_MIN): New macros.
12495 Use them to make the following changes clearer.
12496 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
12497 This change doesn't affect the value now, but it may help remind
12498 future maintainers not to raise the value too much later.
12499 (SELECTION_QUANTUM): Remove, replacing with ...
12500 (selection_quantum): ... new function, which avoids overflow.
12502 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
12503 assumption that selection length fits in 'int'.
12504 (x_reply_selection_request, x_handle_selection_request)
12505 (x_get_window_property, receive_incremental_selection)
12506 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
12507 (lisp_data_to_selection_data, clean_local_selection_data):

12509 (x_reply_selection_request, x_get_window_property)
12510 (receive_incremental_selection, x_property_data_to_lisp):
12511 Redo calculations to avoid overflow.
12512 (x_reply_selection_request): When sending hint, ceiling it at
12513 X_LONG_MAX rather than relying on wraparound overflow to send
12515 (x_get_window_property, receive_incremental_selection)
12516 (lisp_data_to_selection_data, x_property_data_to_lisp):
12517 Check for size-calculation overflow.
12518 (x_get_window_property, receive_incremental_selection)
12519 (lisp_data_to_selection_data, Fx_register_dnd_atom):
12520 Don't store size until memory allocation succeeds.
12521 (x_get_window_property): Plug memory leak on memory exhaustion.
12522 Don't double-block input; malloc is safe here. Don't assume 2**34
12523 - 4 fits in unsigned long. Add an xassert to check
12524 XGetWindowProperty overflow. Be more careful about overflow
12525 calculations, and distinguish size from memory overflow better.
12526 (receive_incremental_selection): When tracing, don't assume
12527 unsigned int is less than INT_MAX.
12528 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
12529 harmful) conversions of unsigned short to int.
12530 (lisp_data_to_selection_data): Don't assume that integers
12531 in the range -65535 through -1 fit in an X unsigned short.
12532 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
12533 result parameters unless successful. Rely on cons_to_unsigned
12534 to report problems with elements; the old code wasn't right anyway.
12535 (x_check_property_data): Check for int overflow; we cannot use
12536 a wider type due to X limits.
12537 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
12539 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.

12568 * image.c (xpm_get_color_table_h):
12569 * lisp.h (hash_lookup, hash_put):
12570 * minibuf.c (Ftest_completion):
12571 Use ptrdiff_t for hash table indexes, not int (which is too
12572 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
12573 32-bit --with-wide-int hosts).
12575 * charset.c (Fdefine_charset_internal): Check for integer overflow.
12576 Add a FIXME comment about memory leaks.
12577 (syms_of_charset): Don't assume xmalloc returns.
12579 Don't assume that stated character widths fit in int.

12581 * character.h (CHAR_WIDTH):
12582 * indent.c (MULTIBYTE_BYTES_WIDTH):
12583 Use sanitize_char_width to avoid undefined and/or bad behavior
12584 with outlandish widths.
12585 * character.h (sanitize_tab_width): Rename from sanitize_width,
12586 now that we have two such functions. All uses changed.
12587 (sanitize_char_width): New inline function.
12589 Don't assume that tab-width fits in int.
12590 * character.h (sanitize_width): New inline function.
12591 (SANE_TAB_WIDTH): New macro.
12592 (ASCII_CHAR_WIDTH): Use it.

12598 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
12600 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
12601 Remove unreachable code.
12602 (read_hex, load_charset_map_from_file): Check for integer overflow.
12604 * xterm.c: Don't go over XClientMessageEvent limit.
12605 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
12606 (x_send_scroll_bar_event): Likewise. Check that the size does not
12607 exceed limits imposed by XClientMessageEvent, as well as the usual
12608 ptrdiff_t and size_t limits.
12610 * keyboard.c: Overflow, signedness and related fixes.
12611 (make_lispy_movement): Use same integer type in forward decl
12612 that is used in the definition.
12613 (read_key_sequence, keyremap_step):
12614 Change bufsize argument back to int, undoing my 2011-03-30 change.
12615 We prefer signed types, and int is wide enough here.
12616 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
12617 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
12618 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
12619 length, not size_t. Use ptrdiff_t for index, not int.
12620 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
12621 possibility of integer overflow.
12623 Overflow, signedness and related fixes for images.

12642 when the callers expect that.
12643 (image_ascent): Redo ascent calculation to avoid int overflow.
12644 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
12645 (lookup_image): Remove unnecessary tests.
12646 (xbm_image_p): Locals are now of int, not EMACS_INT,
12647 since parse_image_check makes sure they fit into int.
12648 (png_load, gif_load, svg_load_image):
12649 Prefer int to unsigned where either will do.
12650 (tiff_handler): New function, combining the cores of the
12651 old tiff_error_handler and tiff_warning_handler.
12652 This function is rewritten to use vsnprintf and thereby avoid
12653 stack buffer overflows. It uses only the features of vsnprintf
12654 that are common to both POSIX and native Microsoft.
12655 (tiff_error_handler, tiff_warning_handler): Use it.
12656 (tiff_load, gif_load, imagemagick_load_image):
12657 Don't assume :index value fits in 'int'.
12658 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
12659 (imagemagick_load_image): Check that crop parameters fit into
12660 the integer types that MagickCropImage accepts. Don't assume
12661 Vimagemagick_render_type has a nonnegative value. Don't assume
12662 size_t fits in 'long'.
12663 (gs_load): Use printmax_t to print the widest integers possible.
12664 Check for integer overflow when computing image height and width.

12673 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
12674 the display spec is of the form `(space ...)'.
12675 (handle_display_spec): Return the value returned by
12676 handle_single_display_spec, not just 1 or zero.
12677 (handle_single_display_spec): If the display spec is of the form
12678 `(space ...)', and specifies display in the text area, return 2
12680 (try_cursor_movement): Check for the need to scroll more
12681 accurately, and prefer exact match for point under bidi.
12682 Don't advance `row' beyond the last row of the window.
12684 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
12685 into disp_prop; all users changed.
12687 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
12688 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
12689 for the text covered by the display property.

12699 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
12700 buffers, return left-to-right.
12701 (set_cursor_from_row): Consider candidate row a win if its glyph
12702 represents a newline and point is on that newline. Fixes cursor
12703 positioning on the newline at EOL of R2L text within L2R
12704 paragraph, and vice versa.
12705 (try_cursor_movement): Check continued rows, in addition to
12706 continuation rows. Fixes unwarranted scroll when point enters a
12707 continued line of R2L text within an L2R paragraph, or vice versa.
12708 (cursor_row_p): Consider the case of point being equal to
12709 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
12710 from the end of a short line to the beginning of a continued line
12711 of R2L text within L2R paragraph.
12712 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
12713 composed characters.

12726 * nsfont.m (ns_otf_to_script): Fix typo.
12728 2011-08-22 Kenichi Handa <handa@m17n.org>
12730 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
12731 extra slot even if the purpose is char-code-property-table.
12733 2011-08-23 Eli Zaretskii <eliz@gnu.org>
12735 * xdisp.c (redisplay_window): When computing centering_position,
12736 account for the height of the header line. (Bug#8874)
12738 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
12739 instead of CHAR_TO_BYTE. Fixes a crash when a completion
12740 candidate is selected by the mouse, and that candidate has a
12741 composed character under the mouse.
12743 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
12744 coordinates reported by pos-visible-in-window-p for a composed
12745 character in column zero.
12747 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
12749 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
12751 2011-08-22 Eli Zaretskii <eliz@gnu.org>
12753 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
12754 consider it a hit if to_charpos is anywhere in the range of the
12755 composed buffer positions.
12757 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
12759 * image.c (gif_load): Don't assume that each subimage has the same
12760 dimensions as the base image. Handle disposal method that is
12761 "undefined" by the gif spec (Bug#9335).
12763 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
12765 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

12768 2011-08-19 Eli Zaretskii <eliz@gnu.org>
12770 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
12771 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
12772 from an Org mode buffer to a Speedbar frame.
12774 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
12775 a composition, take its buffer position from IT->cmp_it.charpos.
12776 Fixes cursor positioning at the beginning of a line that begins
12777 with a composed character.
12779 2011-08-18 Eli Zaretskii <eliz@gnu.org>
12781 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
12782 character bidirectional type, use STRONG_L instead. Fixes crashes
12783 in a buffer produced by `describe-categories'.
12785 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
12786 members before the level stack, so they would be saved and
12787 restored when copying iterator state. Fixes incorrect reordering
12788 around TABs covered by display properties.
12790 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
12792 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

12798 Remove unnecessary aborts (Bug#9081).
12800 2011-08-17 Eli Zaretskii <eliz@gnu.org>
12802 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
12803 has no `load' handler, try opening the file locally. (Bug#9311)
12805 2011-08-16 Ken Brown <kbrown@cornell.edu>
12807 * gmalloc.c: Expand comment.
12809 2011-08-16 Eli Zaretskii <eliz@gnu.org>
12811 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
12812 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.

12860 2011-08-14 Eli Zaretskii <eliz@gnu.org>
12862 * xdisp.c (move_it_in_display_line_to): Don't invoke
12863 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
12864 ppos_it. Fixes vertical cursor motion when line beginning is
12865 covered by an image. (Bug#9296)
12867 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
12869 * nsterm.h (ns_run_ascript): Declare.

12873 (ns_run_ascript): New function.
12874 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
12875 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
12876 the event loop. Get status from as_status (Bug#7276).
12878 * nsterm.m (sendEvent): If event is NSApplicationDefined and
12879 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
12880 the event loop (Bug#7276).
12882 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>

12905 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
12906 (Fnetwork_interface_list): Allocate in increments of bytes instead
12907 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
12908 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
12910 (struct ifflag_def): notrailers is smart on OSX.
12911 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
12912 Get hardware address with getifaddrs if available.
12914 2011-08-12 Eli Zaretskii <eliz@gnu.org>
12916 * xdisp.c (iterate_out_of_display_property): xassert that
12917 IT->position is set to within IT->object's boundaries. Break from
12918 the loop as soon as EOB is reached; avoids infloops in redisplay
12919 when IT->position is set up wrongly due to some bug.
12920 Set IT->current to match the bidi iterator unconditionally.
12921 (push_display_prop): Allow GET_FROM_STRING as IT->method on
12922 entry. Force push_it to save on the stack the current
12923 buffer/string position, to be restored by pop_it. Fix flags in
12924 the iterator structure wrt the object coming from a display
12925 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
12926 properties. (Bug#9284)
12928 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
12930 * fontset.c (fontset_get_font_group): Add proper type checks.

12943 no-display-properties-and-no-overlays under bidi display.
12944 Set disp_pos in the bidi iterator to avoid searches for display
12945 properties and overlays.
12947 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
12949 * editfns.c (Fset_time_zone_rule): Document relationship with the

12955 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
12957 * composite.c (autocmp_chars): Don't reset point. That is done by
12958 restore_point_unwind (Bug#5984).
12960 2011-08-07 Juri Linkov <juri@jurta.org>
12962 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
12963 to show the arg `TIME' instead of `TIMEVAL'.
12965 2011-08-06 Eli Zaretskii <eliz@gnu.org>
12967 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
12968 display property strides EOL and includes a newline, as in
12969 longlines-mode. (Bug#9254)
12970 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
12971 word-wrap under bidirectional display. (Bug#9224)
12973 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
12974 is non-zero, even if the data buffer is NULL. Fixes a crash in
12975 vertical-motion with longlines-mode. (Bug#9254)
12977 2011-08-05 Eli Zaretskii <eliz@gnu.org>
12979 * bidi.c <bidi_cache_total_alloc>: Now static.
12980 (bidi_initialize): Initialize bidi_cache_total_alloc.
12982 * xdisp.c (display_line): Release buffer allocated for shelved bidi
12985 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
12986 amount allocated this far in `bidi_cache_total_alloc'.
12987 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
12988 non-zero, only free the data buffer without restoring the cache
12989 contents. All callers changed.
12991 * dispextern.h (bidi_unshelve_cache): Update prototype.
12993 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
12994 (move_it_in_display_line, move_it_to)
12995 (move_it_vertically_backward, move_it_by_lines): Replace the call
12996 to xfree to an equivalent call to bidi_unshelve_cache.
12997 (move_it_in_display_line_to): Fix logic of returning
12998 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
13000 2011-08-05 Eli Zaretskii <eliz@gnu.org>
13002 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
13003 came from a string character with a `cursor' property. (Bug#9229)
13005 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
13007 * Makefile.in (LIB_PTHREAD): New variable.
13008 (LIBES): Add LIB_PTHREAD (Bug#9216).
13010 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:

13015 * regex.c (re_iswctype): Remove some redundant boolean conversions.
13017 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
13019 * xterm.c (x_find_topmost_parent): New function.
13020 (x_set_frame_alpha): Find topmost parent window with
13021 x_find_topmost_parent and set the property there also (bug#9181).
13022 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
13024 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
13026 * callproc.c (Fcall_process): Avoid vfork clobbering
13027 the local vars buffer, coding_systems, current_dir.
13029 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
13031 * keymap.c (Fmake_composed_keymap): Move to subr.el.
13033 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
13035 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
13036 so that it is not optimized away.
13038 * xdisp.c (compute_display_string_pos): Remove unused local.
13040 2011-08-02 Eli Zaretskii <eliz@gnu.org>
13042 Fix slow cursor motion and scrolling in large buffers with
13043 selective display, like Org Mode buffers. (Bug#9218)
13045 * dispextern.h (struct bidi_it): New member disp_prop_p.
13047 * xdisp.c: Remove one-slot cache of display string positions.
13048 (compute_display_string_pos): Accept an additional argument
13049 DISP_PROP_P; callers changed. Scan at most 5K characters forward
13050 for a display string or property. If found, set DISP_PROP_P
13053 * bidi.c (bidi_fetch_char): Accept an additional argument
13054 DISP_PROP_P, and pass it to compute_display_string_pos.
13055 Only handle text covered by a display string if DISP_PROP_P is returned
13056 non-zero. All callers of bidi_fetch_char changed.
13058 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
13060 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
13062 2010-12-03 Don March <don@ohspite.net>
13064 * keymap.c (Fdefine_key): Fix non-prefix key error message when
13065 last character M-[char] is translated to ESC [char] (bug#7541).
13067 2011-08-02 Kenichi Handa <handa@m17n.org>
13069 * lisp.h (uniprop_table): Extern it.
13071 * chartab.c (uniprop_table): Make it non-static.
13073 2011-08-01 Eli Zaretskii <eliz@gnu.org>
13075 * xdisp.c (forward_to_next_line_start): Accept additional argument
13076 BIDI_IT_PREV, and store into it the state of the bidi iterator had
13078 (reseat_at_next_visible_line_start): Use the bidi iterator state
13079 returned by forward_to_next_line_start to restore the state of
13080 it->bidi_it after backing up to previous newline. (Bug#9212)
13082 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
13084 * regex.c (re_comp): Protoize.
13085 (re_exec): Fix return type.
13086 (regexec): Fix type of `ret'. (Bug#9203)
13088 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
13090 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
13091 This is needed if max-image-size is a floating-point number.
13093 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
13095 * print.c (print_object): Print empty symbol as ##.
13097 * lread.c (read1): Read ## as empty symbol.
13099 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
13101 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
13102 setting frame foreground color (Bug#9175).
13103 (x_set_background_color): Likewise.
13105 * nsmenu.m (-setText): Size tooltip dimensions precisely to
13106 contents (Bug#9176).
13107 (EmacsTooltip -init): Remove bezels and add shadows to
13110 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
13111 or scroll bar (Bug#8470).
13113 * nsfont.m (nsfont_open): Remove assignment to voffset and
13114 unnecessary vars hshink, expand, hd, full_height, min_height.
13115 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
13117 * nsterm.h (nsfont_info): Remove voffset field.
13119 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
13121 Implement strike-through and overline on NextStep (Bug#8863).
13123 * nsfont.m (nsfont_open): Use underline position provided by font,
13124 instead of hard-coded value of 2.
13125 (nsfont_draw): Call ns_draw_text_decoration instead.
13127 * nsterm.h: Add declaration for ns_draw_text_decoration.
13129 * nsterm.m (ns_draw_text_decoration): New function for drawing
13130 underline, overline, and strike-through.
13131 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
13132 ns_draw_text_decoration. Change treatment of cursor drawing to
13133 accommodate underlining, etc.
13135 2011-07-28 Eli Zaretskii <eliz@gnu.org>
13137 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
13140 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
13142 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
13143 Without this fix, if a signal arrives just after memory fills up,
13144 'malloc' might be invoked reentrantly.
13146 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
13147 In other words, assume that every image size is allowed, on non-X
13148 hosts. This assumption is probably wrong, but it lets Emacs compile.
13150 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
13152 * regex.c (re_iswctype): Convert return values to boolean.
13154 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
13156 * xdisp.c (compute_display_string_pos): Don't use cached display
13157 string position if the buffer had its restriction changed.
13160 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
13162 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
13164 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
13166 Integer signedness and overflow and related fixes. (Bug#9079)
13168 * bidi.c: Integer size and overflow fixes.
13169 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
13170 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
13171 (bidi_cache_find_level_change, bidi_cache_ensure_space)
13172 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
13173 (bidi_find_other_level_edge):
13174 Use ptrdiff_t instead of EMACS_INT where either will do.
13175 This works better on 32-bit hosts configured --with-wide-int.
13176 (bidi_cache_ensure_space): Check for size-calculation overflow.
13177 Use % rather than repeated addition, for better worst-case speed.
13178 Don't set bidi_cache_size until after xrealloc returns, because it
13180 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
13181 (bidi_cache_ensure_space): Also check that the bidi cache size
13182 does not exceed that of the largest Lisp string or buffer. See Eli
13183 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
13185 * alloc.c (__malloc_size_t): Remove.
13186 All uses replaced by size_t. See Andreas Schwab's note
13187 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
13189 * image.c: Improve checking for integer overflow.
13190 (check_image_size): Assume that f is nonnull, since
13191 it is always nonnull in practice. This is one less thing to
13192 worry about when checking for integer overflow later.
13193 (x_check_image_size): New function, which checks for integer
13194 overflow issues inside X.
13195 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
13196 This removes the need for a memory_full check.
13197 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
13198 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
13199 (xbm_read_bitmap_data): Change locals back to 'int', since
13200 their values must fit in 'int'.
13201 (xpm_load_image, png_load, tiff_load):
13202 Invoke x_create_x_image_and_pixmap earlier,
13203 to avoid much needless work if the image is too large.
13204 (tiff_load): Treat overly large images as if
13205 x_create_x_image_and_pixmap failed, not as malloc failures.
13206 (gs_load): Use x_check_image_size.
13208 * gtkutil.c: Omit integer casts.
13209 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
13210 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
13212 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
13214 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
13215 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
13216 would wrongly return t on a 64-bit host.
13218 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
13219 The plain *_OVERFLOW macros run afoul of GCC bug 49705
13220 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
13221 and therefore cause GCC to emit a bogus diagnostic in some cases.
13223 * image.c: Integer signedness and overflow and related fixes.
13224 This is not an exhaustive set of fixes, but it's time to
13225 record what I've got.
13226 (lookup_pixel_color, check_image_size): Remove redundant decls.
13227 (check_image_size): Don't assume that arbitrary EMACS_INT values
13228 fit in 'int', or that arbitrary 'double' values fit in 'int'.
13229 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
13230 (tiff_load, imagemagick_load_image):
13231 Check for overflow in size calculations.
13232 (x_create_x_image_and_pixmap): Remove unnecessary test for
13233 xmalloc returning NULL; that can't happen.
13234 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
13235 (xpm_color_bucket): Use better integer hashing function.
13236 (xpm_cache_color): Don't possibly over-allocate memory.
13237 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
13238 (gif_memory_source):
13239 Use ptrdiff_t, not int or size_t, to record sizes.
13240 (png_load): Don't assume values greater than 2**31 fit in 'int'.
13241 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
13242 either works, as we prefer signed integers.
13243 (tiff_read_from_memory, tiff_write_from_memory):
13244 Return tsize_t, not size_t, since that's what the TIFF API wants.
13245 (tiff_read_from_memory): Don't fail simply because the read would
13246 go past EOF; instead, return a short read.
13247 (tiff_load): Omit no-longer-needed casts.
13248 (Fimagemagick_types): Don't assume size fits into 'int'.
13250 Improve hashing quality when configured --with-wide-int.
13251 * fns.c (hash_string): New function, taken from sxhash_string.
13252 Do not discard information about ASCII character case; this
13253 discarding is no longer needed.
13254 (sxhash-string): Use it. Change sig to match it. Caller changed.
13255 * lisp.h: Declare it.
13256 * lread.c (hash_string): Remove, since we now use fns.c's version.
13257 The fns.c version returns a wider integer if --with-wide-int is
13258 specified, so this should help the quality of the hashing a bit.
13260 * emacs.c: Integer overflow minor fix.
13261 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
13262 Define only if GNU_LINUX.
13263 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
13265 * dispnew.c: Integer signedness and overflow fixes.
13266 Remove unnecessary forward decls, that were a maintenance hassle.
13267 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
13269 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
13270 (scrolling_window): Use ptrdiff_t, not int, for byte count.
13271 (prepare_desired_row, line_draw_cost):
13272 Use int, not unsigned, where either works.
13273 (save_current_matrix, restore_current_matrix):
13274 Use ptrdiff_t, not size_t, where either works.
13275 (init_display): Check for overflow more accurately, and without
13276 relying on undefined behavior.
13278 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
13279 Remove, replacing with the new symbols in lisp.h. All uses changed.
13280 * fileio.c (make_temp_name):
13281 * filelock.c (lock_file_1, lock_file):
13282 * xdisp.c (message_dolog):
13283 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
13284 Use pMd etc. instead.
13285 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
13286 replacing the pWIDE etc. symbols removed from editfns.c.
13288 * keyboard.h (num_input_events): Now uintmax_t.
13289 This is (very slightly) less likely to mess up due to wraparound.
13292 * buffer.c: Integer signedness fixes.
13293 (alloc_buffer_text, enlarge_buffer_text):
13294 Use ptrdiff_t rather than size_t when either will do, as we prefer
13297 * alloc.c: Integer signedness and overflow fixes.
13298 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
13299 (__malloc_size_t): Default to size_t, not to int.
13300 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
13301 (Fgarbage_collect, mark_object_loop_halt, mark_object):
13302 Prefer ptrdiff_t to size_t when either would do, as we prefer
13304 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
13305 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
13306 Now const. Initialize with values that are in range even if char
13308 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
13309 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
13310 These functions do the right thing with sizes > 2**32.
13311 (check_depth): Now ptrdiff_t, not int.
13312 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
13313 Adjust to new way of storing sizes. Check for size overflow bugs
13315 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
13316 slightly wrong anyway, as it missed one instance of
13317 XMALLOC_OVERRUN_CHECK_OVERHEAD.
13318 (refill_memory_reserve): Omit needless cast to size_t.
13319 (mark_object_loop_halt): Mark as externally visible.
13321 * xselect.c: Integer signedness and overflow fixes.
13322 (Fx_register_dnd_atom, x_handle_dnd_message):
13323 Use ptrdiff_t, not size_t, since we prefer signed.
13324 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
13325 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
13326 x_dnd_atoms_size and x_dnd_atoms_length.
13328 * doprnt.c: Prefer signed to unsigned when either works.
13330 * doprnt.c (doprnt):
13332 * xdisp.c (vmessage):
13333 Use ptrdiff_t, not size_t, when using or implementing doprnt,
13334 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
13335 prefer signed arithmetic to avoid comparison confusion.
13336 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
13337 but is a bit tricky.
13339 Assume freestanding C89 headers, string.h, stdlib.h.
13340 * data.c, doprnt.c, floatfns.c, print.c:
13341 Include float.h unconditionally.
13342 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
13343 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
13344 * regex.c: Likewise for stddef.h, string.h.
13345 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
13346 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
13347 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
13348 (STDC_HEADERS): Remove obsolete defines.
13349 * sysdep.c: Include limits.h unconditionally.
13351 Assume support for memcmp, memcpy, memmove, memset.
13352 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
13353 * regex.c (memcmp, memcpy):
13354 Remove; we assume C89 now.
13356 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
13357 (__malloc_safe_bcopy): Remove; no longer needed.
13359 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
13360 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
13361 well either way, and we prefer signed to unsigned.
13363 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
13365 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
13366 closes the connection while we're reading (bug#9182).
13368 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
13370 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
13371 are specified (Bug#9168).
13373 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
13375 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
13376 Found by GCC static checking and --with-wide-int on a 32-bit host.
13378 2011-07-25 Eli Zaretskii <eliz@gnu.org>
13380 * xdisp.c (compute_display_string_pos): Fix logic of caching
13381 previous display string position. Initialize cached_prev_pos to
13382 -1. Fixes slow-down at the beginning of a buffer.
13384 2011-07-24 Eli Zaretskii <eliz@gnu.org>
13386 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
13387 for attrs[LFACE_FONTSET_INDEX].
13389 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
13391 * xml.c (parse_region): Remove unused local
13392 that was recently introduced.
13394 2011-07-23 Eli Zaretskii <eliz@gnu.org>
13396 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
13397 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
13399 * xdisp.c (move_it_in_display_line_to): Record the best matching
13400 position for TO_CHARPOS while scanning the line, and restore it on
13401 exit if none of the characters scanned was an exact match.
13402 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
13403 when exact match is impossible due to invisible text, and the
13404 lines are truncated.
13406 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
13408 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
13411 2011-07-22 Eli Zaretskii <eliz@gnu.org>
13413 Fix a significant slow-down of cursor motion with C-n, C-p,
13414 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
13415 auto-repeat under bidi redisplay in fontified buffers.
13416 * xdisp.c (compute_stop_pos_backwards): New function.
13417 (next_element_from_buffer): Call compute_stop_pos_backwards to
13418 find a suitable prev_stop when we find ourselves before
13420 (reseat): Don't look for prev_stop, as that could mean a very long
13422 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
13423 <cached_disp_overlay_modiff>: Cache for last found display string
13425 (compute_display_string_pos): Return the cached position if asked
13426 about the same buffer in the same area of character positions, and
13427 the buffer wasn't changed since the time the display string
13428 position was cached.
13430 2011-07-22 Eli Zaretskii <eliz@gnu.org>
13432 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
13433 is an integer, which is important for empty lines. (Bug#9149)
13435 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
13437 * frame.c (Fmodify_frame_parameters): In tty case, update the
13438 default face if necessary (Bug#4238).
13440 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
13442 * editfns.c (Fstring_to_char): No need to explain what a character
13443 is in the docstring (Bug#6576).
13445 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
13447 * xml.c (parse_region): Make sure we always return a tree.
13449 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
13451 * xml.c (parse_region): If a document contains only comments,
13454 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
13456 * xml.c (make_dom): Return comments, too.

13463 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
13464 rather than fgets, and retry after EINTR. Otherwise, 'emacs
13465 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
13467 * s/openbsd.h (BROKEN_SIGIO): Define.
13468 * unexelf.c (unexec) [__OpenBSD__]:
13469 Don't update the .mdebug section of the Alpha COFF symbol table.
13471 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
13473 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
13476 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
13478 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
13479 This fixes some race conditions on the permissions of any newly
13482 * alloc.c (valid_pointer_p): Use pipe, not open.
13483 This fixes some permissions issues when debugging.
13485 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
13486 If fchown fails to set both uid and gid, try to set just gid,
13487 as that is sometimes allowed. Adjust the file's mode to eliminate
13488 setuid or setgid bits that are inappropriate if fchown fails.
13490 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
13492 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
13493 to compare Lisp_Objects.

13498 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
13500 * lread.c (read_integer): Unread even EOF character.
13501 (read1): Likewise. Properly record start position of symbol.
13503 * lread.c (read1): Read `#:' as empty uninterned symbol if no
13504 symbol character follows.
13506 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
13508 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
13509 This works around a problem with the previous change to Fcopy_file.
13510 Recent glibc declares fchown with __attribute__((warn_unused_result)),
13511 and without this change, GCC might complain about discarding
13512 fchown's return value.
13514 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
13516 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
13518 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
13520 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
13522 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
13524 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
13525 it's used from the C level.
13527 * process.c: Use the same condition for POLL_FOR_INPUT in both
13528 keyboard.c and process.c (bug#1858).
13530 2011-07-09 Lawrence Mitchell <wence@gmx.li>
13532 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
13533 (Fgnutls_boot): Use it.
13535 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
13537 * doc.c (Fsubstitute_command_keys): Revert last change.
13539 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
13541 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
13542 quotes the next character, and doesn't affect other longer
13543 sequences (bug#8935).
13545 * lread.c (syms_of_lread): Clarify that is isn't only
13546 `eval-buffer' and `eval-defun' that's affected by
13547 `lexical-binding' (bug#8460).
13549 2011-07-15 Eli Zaretskii <eliz@gnu.org>
13551 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
13552 bidi redisplay when a line includes both an image and is truncated.
13554 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
13556 Fix minor problems found by static checking.
13557 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
13558 (elsz): Now a signed constant, not a size_t var. We prefer signed
13559 types to unsigned, to avoid integer comparison confusion. Without
13560 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
13561 "cannot optimize loop, the loop counter may overflow", a symptom
13563 * indent.c (Fvertical_motion): Mark locals as initialized.
13564 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
13566 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>

13592 (display_string): If we need to ignore text properties of
13593 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
13594 original value of -1 will not work with bidi.)
13595 (compute_display_string_pos): First arg is now struct
13596 `text_pos *'; all callers changed. Support display properties on

13600 (init_iterator, reseat_1, reseat_to_string): Initialize the
13601 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
13602 when iterating on a string not from display properties).
13603 (compute_display_string_pos, compute_display_string_end):
13604 Fix calculation of the object to scan. Fixes an error when using
13606 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
13607 base_level_stop; instead, set base_level_stop to BEGV.
13608 Fixes crashes in vertical-motion.
13609 (next_element_from_buffer): Improve commentary for when
13610 the iterator is before prev_stop.
13611 (init_iterator): Initialize bidi_p from the default value of
13612 bidi-display-reordering, not from buffer-local value. Use the
13613 buffer-local value only if initializing for buffer iteration.

13634 parts of next_element_from_buffer, next_element_from_string, and
13635 next_element_from_c_string.
13636 (tool_bar_lines_needed, redisplay_tool_bar)
13637 (display_menu_bar): Force left-to-right direction. Add a FIXME

13652 pushed the iterator stack, restore the internal state of the bidi
13653 iterator by calling bidi_pop_it same number of times.
13654 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
13655 and we are bidi-iterating, don't decrement the iterator position;
13656 instead, set the first_elt flag in the bidi iterator, to produce
13658 (reseat_1): Remove redundant setting of string_from_display_prop_p.
13659 (push_display_prop): xassert that we are iterating a buffer.

13663 (push_display_prop): Set up the `unibyte' member of bidi_it.string
13664 correctly. Don't assume unibyte strings are not bidi-reordered.

13673 property. Fix a typo in popping stretch info. Add an assertion
13674 for verifying that the iterator position is in sync with the bidi
13676 (handle_single_display_spec, get_overlay_strings_1)

13765 (bidi_push_it, bidi_pop_it): Add prototypes.
13766 (struct iterator_stack_entry): New members bidi_p,
13767 paragraph_embedding, and from_disp_prop_p.

14088 (clone_per_buffer_values): Don't assume that

14090 This isn't true in general, and it's particularly not true
14091 if Emacs is configured with --with-wide-int.
14092 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
14093 New macros, used in the buffer.c change.

14129 Random fixes. E.g., (random) never returned negative values.
14130 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
14131 subseconds part to the entropy, as that's a bit more random.
14132 Prefer signed to unsigned, since the signedness doesn't matter and
14133 in general we prefer signed. When given a limit, use a
14134 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
14135 latter isn't right if USE_2_TAGS_FOR_INTS.
14136 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
14137 not 0..VALMASK. Don't discard "excess" bits that random () returns.

14149 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
14150 This is more efficient than Ffile_directory_p and avoids a minor race.
14152 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
14154 * buffer.c (Foverlay_put): Say what the return value is
14157 * fileio.c (barf_or_query_if_file_exists): Check first if the file
14158 is a directory before asking whether to use the file name
14160 (barf_or_query_if_file_exists): Make the "File is a directory"
14161 error be more correct.
14163 * fns.c (Frequire): Remove the mention of the .gz files, since
14164 that's installation-specific, but keep the mention of
14165 `get-load-suffixes'.

14169 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

14177 Qgnutls_bootprop_verify_error (which is no longer used).
14179 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
14180 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
14181 Also (re)move comments that are misplaced or no longer relevant.

14208 2011-07-02 Lars Magne Ingebrigtsen <larsi@gnus.org>
14210 * lread.c (syms_of_lread): Mention single symbols defined by

14244 (syms_of_keymap): Defsubr make-composed-keymap.
14245 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

14282 * eval.c (struct backtrace): Simplify and port the data structure.
14283 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
14284 signed bit field, as this assumption is not portable and it makes
14285 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
14286 "char debug_on_exit : 1" as this is not portable either; instead,
14287 use the portable "unsigned int debug_on_exit : 1". Remove unused
14288 member evalargs. Remove obsolete comments about cc bombing out.
14290 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

14376 2011-06-26 Chong Yidong <cyd@stupidchicken.com>
14378 * process.c (wait_reading_process_output): Bypass select if
14379 waiting for a cell while ignoring keyboard input, and input is
14380 pending. Suggested by Jan Djärv (Bug#8869).
14382 2011-06-25 Paul Eggert <eggert@cs.ucla.edu>
14384 Use gnulib's dup2 module instead of rolling our own.
14385 * sysdep.c (dup2) [!HAVE_DUP2]: Remove; gnulib now does this.

14456 * print.c (printchar, strout): Check for string overflow.
14457 (PRINTPREPARE, printchar, strout):
14458 Don't set size unless allocation succeeds.
14460 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
14461 for sizes. Check for string overflow more accurately.
14462 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
14464 * macros.c: Integer and buffer overflow fixes.
14465 * keyboard.h (struct keyboard.kbd_macro_bufsize):
14466 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

14470 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
14472 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
14474 * lread.c: Integer overflow fixes.
14475 (read_integer): Radix is now EMACS_INT, not int,
14476 to improve quality of diagnostics for out-of-range radices.
14477 Calculate buffer size correctly for out-of-range radices.
14478 (read1): Check for integer overflow in radices, and in
14479 read-circle numbers.
14480 (read_escape): Avoid int overflow.
14481 (Fload, openp, read_buffer_size, read1)
14482 (substitute_object_recurse, read_vector, read_list, map_obarray):

14498 2011-06-22 Leo Liu <sdl.web@gmail.com>
14500 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
14501 Move to minibuffer.el.
14503 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
14505 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
14506 The following patches are for when GLYPH_DEBUG && !XASSERT.
14507 * dispextern.h (trace_redisplay_p, dump_glyph_string):
14508 * dispnew.c (flush_stdout):
14509 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
14510 Mark as externally visible.
14511 * dispnew.c (check_window_matrix_pointers): Now static.
14512 * dispnew.c (window_to_frame_vpos):
14513 * xfns.c (unwind_create_frame):
14514 * xterm.c (x_check_font): Remove unused local.
14515 * scroll.c (CHECK_BOUNDS):
14516 * xfaces.c (cache_fache): Rename local to avoid shadowing.
14517 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
14518 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
14519 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
14520 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
14522 (debug_method_add): Use va_list and vsprintf rather than relying
14523 on undefined behavior with wrong number of arguments.
14524 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
14525 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
14526 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
14527 since we're not interested in debugging glyphs with old libraries.
14528 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
14529 GCC 4.6.0's static checking.
14531 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
14533 Integer overflow and signedness fixes (Bug#8873).

14549 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
14550 (.bitmaps_last, struct x_output.icon_bitmap):
14551 Use ptrdiff_t, not int, for bitmap indexes.
14552 (x_allocate_bitmap_record): Check for size overflow.
14553 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
14555 Use ptrdiff_t, not int, for overlay counts.
14556 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
14557 * editfns.c (overlays_around, get_pos_property):

14559 * xdisp.c (next_overlay_change, note_mouse_highlight):
14560 * xfaces.c (face_at_buffer_position):
14561 * buffer.c (OVERLAY_COUNT_MAX): New macro.
14562 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
14563 (Fnext_overlay_change, Fprevious_overlay_change)
14564 (mouse_face_overlay_overlaps, Foverlays_in):
14565 Use ptrdiff_t, not int, for sizes.
14566 (overlays_at, overlays_in): Check for size-calculation overflow.
14568 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
14570 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
14571 (x_session_initialize): Do not assume string length fits in int.
14573 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
14574 This is unlikely, but can occur if DPI is outlandish.
14576 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
14577 * xselect.c (Fx_get_atom_name): Avoid need for strlen.

14580 * xrdb.c (magic_file_p, search_magic_path):
14581 Omit last arg SUFFIX; it was always 0. All callers changed.
14582 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
14584 * xfont.c (xfont_match): Avoid need for strlen.
14586 * xfns.c: Don't assume strlen fits in int.

14589 * xdisp.c (message_log_check_duplicate): Return intmax_t,
14590 not unsigned long, as we prefer signed integers. All callers changed.
14591 Detect integer overflow in repeat count.
14592 (message_dolog): Don't assume print length fits in 39 bytes.
14593 (display_mode_element): Don't assume strlen fits in int.
14595 * termcap.c: Don't assume sizes fit in int and never overflow.
14596 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
14597 (gobble_line): Check for size-calculation overflow.
14599 * minibuf.c (Fread_buffer):
14600 * lread.c (intern, intern_c_string):

14614 * filelock.c: Fix some buffer overrun and integer overflow issues.
14615 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
14616 Reformulate so as not to need the command string.
14617 Invoke gzip -cd rather than gunzip, as it's more portable.
14618 (lock_info_type, lock_file_1, lock_file):
14619 Don't assume pid_t and time_t fit in unsigned long.
14620 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
14621 (current_lock_owner): Prefer signed type for sizes.
14622 Use memcpy, not strncpy, where memcpy is what is really wanted.
14623 Don't assume (via atoi) that time_t and pid_t fit in int.
14624 Check for time_t and/or pid_t out of range, e.g., via a network share.
14625 Don't alloca where an auto var works fine.
14627 * fileio.c: Fix some integer overflow issues.
14628 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
14629 Don't assume string length fits in int.
14630 (directory_file_name): Don't assume string length fits in long.
14631 (make_temp_name): Don't assume pid fits in int, or that its print
14632 length is less than 20.

14651 (Fgetenv_internal):
14652 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
14654 * lread.c (invalid_syntax): Omit length argument.
14655 All uses changed. This doesn't fix a bug, but it simplifies the
14656 code away from its former Hollerith-constant appearance, and it's
14657 one less 'int' to worry about when looking at integer-overflow issues.
14658 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
14660 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
14661 This didn't break anything, but it didn't help either.
14662 It's confusing to put a bogus integer in a place where the actual
14663 value does not matter.
14664 (LIST_END_P): Remove unused macro and its bogus comment.
14665 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
14667 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
14668 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
14670 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
14671 We prefer signed types, and the value cannot exceed the EMACS_INT
14672 range anyway (because otherwise the length would not be representable).
14673 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
14674 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
14675 This avoids a GCC warning when WIDE_EMACS_INT.
14677 * indent.c (sane_tab_width): New function.
14678 (current_column, scan_for_column, Findent_to, position_indentation)
14679 (compute_motion): Use it. This is just for clarity.
14680 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
14682 * image.c (xbm_image_p): Don't assume stated width, height fit in int.

14686 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
14688 * editfns.c, insdel.c:
14689 Omit unnecessary forward decls, to simplify future changes.
14691 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
14693 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
14695 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
14696 Use much-faster test for byte-length change.
14697 Don't assume string byte-length fits in 'int'.
14698 Check that character arg fits in 'int'.
14699 (mapcar1): Declare byte as byte, for clarity.
14701 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
14703 * fns.c (concat): Catch string overflow earlier.
14704 Do not rely on integer wraparound.
14706 * dispextern.h (struct it.overlay_strings_charpos)
14707 (struct it.selective): Now EMACS_INT, not int.
14708 * xdisp.c (forward_to_next_line_start)
14709 (back_to_previous_visible_line_start)
14710 (reseat_at_next_visible_line_start, next_element_from_buffer):
14711 Don't arbitrarily truncate the value of 'selective' to int.
14713 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
14715 * composite.c: Don't truncate sizes to 'int'.
14716 (composition_gstring_p, composition_reseat_it)
14717 (composition_adjust_point): Use EMACS_INT, not int.
14718 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
14719 not EMACS_UINT, for indexes.
14721 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
14723 * buffer.c: Include <verify.h>.
14724 (struct sortvec.priority, struct sortstr.priority):
14725 Now EMACS_INT, not int.
14726 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
14727 (struct sortstr.size, record_overlay_string)
14728 (struct sortstrlist.size, struct sortlist.used):
14729 Don't truncate size to int.
14730 (record_overlay_string): Check for size-calculation overflow.
14731 (init_buffer_once): Check at compile-time, not run-time.
14733 2011-06-22 Jim Meyering <meyering@redhat.com>
14735 Don't leak an XBM-image-sized buffer
14736 * image.c (xbm_load): Free the image buffer after using it.
14738 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
14741 * composite.c (find_automatic_composition): Omit needless 'return 0;'
14742 that Sun C diagnosed.
14743 * fns.c (secure_hash): Fix pointer signedness issue.
14744 * intervals.c (static_offset_intervals): New function.
14745 (offset_intervals): Use it.
14747 2011-06-21 Leo Liu <sdl.web@gmail.com>
14750 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
14753 * fns.c (secure_hash): Rename from crypto_hash_function and change
14754 the first arg to accept symbols.
14755 (Fsecure_hash): New primitive.
14756 (syms_of_fns): New symbols.
14758 2011-06-20 Deniz Dogan <deniz@dogan.se>
14760 * process.c (Fset_process_buffer): Clarify return value in

14774 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
14775 check till after the cache is created in init_frame_faces.
14777 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
14779 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
14781 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
14783 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
14784 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
14785 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
14787 Improve buffer-overflow checking (Bug#8873).
14788 * fileio.c (Finsert_file_contents):
14789 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
14790 Remove the old (too-loose) buffer overflow checks.
14791 They weren't needed, since make_gap checks for buffer overflow.
14792 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
14793 The old code merely checked for Emacs fixnum overflow, and relied
14794 on undefined (wraparound) behavior. The new code avoids undefined
14795 behavior, and also checks for ptrdiff_t and/or size_t overflow.
14797 * editfns.c (Finsert_char): Don't dump core with very negative counts.
14798 Tune. Don't use wider integers than needed. Don't use alloca.
14799 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
14801 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
14803 * insdel.c, lisp.h (buffer_overflow): New function.
14804 (insert_from_buffer_1, replace_range, replace_range_2):
14805 * insdel.c (make_gap_larger):
14806 * editfns.c (Finsert_char):
14807 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
14809 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
14811 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
14813 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
14815 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
14816 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
14818 * fileio.c: Don't assume EMACS_INT fits in off_t.
14819 (emacs_lseek): New static function.
14820 (Finsert_file_contents, Fwrite_region): Use it.
14821 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
14823 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
14825 * fns.c: Don't overflow int when computing a list length.
14826 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
14827 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
14828 truncation on 64-bit hosts. Check for QUIT every
14829 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
14830 faster and is responsive enough.
14831 (Flength): Report an error instead of overflowing an integer.
14832 (Fsafe_length): Return a float if the value is not representable
14833 as a fixnum. This shouldn't happen except in contrived situations.
14834 (Fnthcdr, Fsort): Don't assume list length fits in int.
14835 (Fcopy_sequence): Don't assume vector length fits in int.
14837 * alloc.c: Check that resized vectors' lengths fit in fixnums.
14838 (header_size, word_size): New constants.
14839 (allocate_vectorlike): Don't check size overflow here.
14840 (allocate_vector): Check it here instead, since this is the only
14841 caller of allocate_vectorlike that could cause overflow.
14842 Check that the new vector's length is representable as a fixnum.
14844 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
14845 The previous code was bogus. For example, next_almost_prime (32)
14846 returned 39, which is undesirable as it is a multiple of 3; and
14847 next_almost_prime (24) returned 25, which is a multiple of 5 so
14848 why was the code bothering to check for multiples of 7?
14850 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
14852 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
14854 Variadic C functions now count arguments with ptrdiff_t.
14855 This partly undoes my 2011-03-30 change, which replaced int with size_t.
14856 Back then I didn't know that the Emacs coding style prefers signed int.
14857 Also, in the meantime I found a few more instances where arguments
14858 were being counted with int, which may truncate counts on 64-bit
14859 machines, or EMACS_INT, which may be unnecessarily wide.
14860 * lisp.h (struct Lisp_Subr.function.aMANY)
14861 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
14862 Arg counts are now ptrdiff_t, not size_t.
14863 All variadic functions and their callers changed accordingly.
14864 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
14865 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
14866 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
14867 * callint.c (Fcall_interactively): Check arg count for overflow,
14868 to avoid potential buffer overrun. Use signed char, not 'int',
14869 for 'varies' array, so that we needn't bother to check its size
14870 calculation for overflow.
14871 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
14872 * eval.c (apply_lambda):
14873 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
14874 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
14875 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
14877 * callint.c (Fcall_interactively): Don't use index var as event count.
14879 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
14880 * mem-limits.h (SIZE): Remove; no longer used.
14882 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
14884 Remove unnecessary casts.
14885 * xterm.c (x_term_init):
14886 * xfns.c (x_set_border_pixel):
14887 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
14888 These aren't needed now that we assume ANSI C.
14890 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
14891 It's more likely to cause problems (due to unsigned overflow)
14894 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
14896 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
14898 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
14900 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
14902 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
14904 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
14906 GLYPH_CODE_FACE returns EMACS_INT, not int.
14907 * dispextern.h (merge_faces):
14908 * xfaces.c (merge_faces):
14909 * xdisp.c (get_next_display_element, next_element_from_display_vector):
14910 Don't assume EMACS_INT fits in int.
14912 * character.h (CHAR_VALID_P): Remove unused parameter.
14913 * fontset.c, lisp.h, xdisp.c: All uses changed.
14915 * editfns.c (Ftranslate_region_internal): Omit redundant test.
14917 * fns.c (concat): Minor tuning based on overflow analysis.
14918 This doesn't fix any bugs. Use int to hold character, instead
14919 of constantly refetching from Emacs object. Use XFASTINT, not
14920 XINT, for value known to be a character. Don't bother comparing
14921 a single byte to 0400, as it's always less.
14923 * floatfns.c (Fexpt):
14924 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
14926 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
14929 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
14931 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
14932 Without this fix, on a 64-bit host (aset S 0 4294967386) would
14933 incorrectly succeed when S was a string, because 4294967386 was
14934 truncated before it was used.
14936 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
14937 Otherwise, an out-of-range integer could cause undefined behavior
14940 * composite.c: Use int, not EMACS_INT, for characters.
14941 (fill_gstring_body, composition_compute_stop_pos): Use int, not
14942 EMACS_INT, for values that are known to be in character range.
14943 This doesn't fix any bugs but is the usual style inside Emacs and
14944 may generate better code on 32-bit machines.
14946 Make sure a 64-bit char is never passed to ENCODE_CHAR.
14947 This is for reasons similar to the recent CHAR_STRING fix.
14948 * charset.c (Fencode_char): Check that character arg is actually
14949 a character. Pass an int to ENCODE_CHAR.
14950 * charset.h (ENCODE_CHAR): Verify that the character argument is no
14951 wider than 'int', as a compile-time check to prevent future regressions
14954 * character.c (char_string): Remove unnecessary casts.
14956 Make sure a 64-bit char is never passed to CHAR_STRING.
14957 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
14958 by silently ignoring the top 32 bits, allowing some values
14959 that were far too large to be valid characters.
14960 * character.h: Include <verify.h>.
14961 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
14962 arguments are no wider than unsigned, as a compile-time check
14963 to prevent future regressions in this area.
14965 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
14966 (Fsubst_char_in_region):
14968 * xdisp.c (decode_mode_spec_coding):
14969 Adjust to CHAR_STRING's new requirement.
14970 * editfns.c (Finsert_char, Fsubst_char_in_region):
14971 * fns.c (concat): Check that character args are actually
14972 characters. Without this test, these functions did the wrong
14973 thing with wildly out-of-range values on 64-bit hosts.
14975 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
14976 These casts should not be needed on 32-bit hosts, either.
14977 * keyboard.c (read_char):
14978 * lread.c (Fload): Remove casts to unsigned.
14980 * lisp.h (UNSIGNED_CMP): New macro.
14981 This fixes comparison bugs on 64-bit hosts.
14982 (ASCII_CHAR_P): Use it.
14983 * casefiddle.c (casify_object):
14984 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
14985 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
14986 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
14987 * dispextern.h (FACE_FROM_ID):
14988 * keyboard.c (read_char): Use UNSIGNED_CMP.
14990 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
14991 not to EMACS_INT, to avoid GCC warning.
14993 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
14995 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
14996 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
14997 isn't needed on 32-bit machines.
14999 * buffer.c (Fgenerate_new_buffer_name):
15000 Use EMACS_INT for count, not int.
15001 (advance_to_char_boundary): Return EMACS_INT, not int.
15003 * data.c (Qcompiled_function): Now static.
15005 * window.c (window_body_lines): Now static.
15007 * image.c (gif_load): Rename local to avoid shadowing.
15009 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
15010 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
15011 * alloc.c (make_save_value): Integer argument is now of type
15012 ptrdiff_t, not int.
15013 (mark_object): Use ptrdiff_t, not int.
15014 * lisp.h (pD): New macro.
15015 * print.c (print_object): Use it.
15017 * alloc.c: Use EMACS_INT, not int, to count objects.
15018 (total_conses, total_markers, total_symbols, total_vector_size)
15019 (total_free_conses, total_free_markers, total_free_symbols)
15020 (total_free_floats, total_floats, total_free_intervals)
15021 (total_intervals, total_strings, total_free_strings):
15022 Now EMACS_INT, not int. All uses changed.
15023 (Fgarbage_collect): Compute overall total using a double, so that
15024 integer overflow is less likely to be a problem. Check for overflow
15025 when converting back to an integer.
15026 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
15027 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
15028 These were 'int' variables that could overflow on 64-bit hosts;
15029 they were never used, so remove them instead of repairing them.
15030 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
15031 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
15032 Previously, this ceilinged at INT_MAX, but that doesn't work on
15034 (allocate_pseudovector): Don't use EMACS_INT when int would do.
15036 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
15037 (allocate_vectorlike): Check for ptrdiff_t overflow.
15038 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
15039 when a (possibly-narrower) signed value would do just as well.
15040 We prefer using signed arithmetic, to avoid comparison confusion.
15042 * alloc.c: Catch some string size overflows that we were missing.
15043 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
15044 for convenience in STRING_BYTES_MAX.
15045 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
15046 The definition here is exact; the one in lisp.h was approximate.
15047 (allocate_string_data): Check for string overflow. This catches
15048 some instances we weren't catching before. Also, it catches
15049 size_t overflow on (unusual) hosts where SIZE_MAX <= min
15050 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
15051 and ptrdiff_t and EMACS_INT are both 64 bits.
15053 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
15054 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
15055 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
15057 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
15059 * alloc.c (Fmake_string): Check for out-of-range init.
15061 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
15063 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
15065 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
15067 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
15068 xg_get_default_scrollbar_width.
15070 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
15071 (int_gtk_range_get_value): Move to the scroll bar part of the file.
15072 (style_changed_cb): Call update_theme_scrollbar_width and call
15073 x_set_scroll_bar_default_width and xg_frame_set_char_size for
15074 all frames (Bug#8505).
15075 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
15076 Call gtk_window_set_resizable if HAVE_GTK3.
15077 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
15078 and height if HAVE_GTK3 (Bug#8505).
15079 (scroll_bar_width_for_theme): New variable.
15080 (update_theme_scrollbar_width): New function.
15081 (xg_get_default_scrollbar_width): Move code to
15082 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
15083 (xg_initialize): Call update_theme_scrollbar_width.
15085 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
15087 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
15089 2011-06-12 Martin Rudalics <rudalics@gmx.at>
15091 * frame.c (make_frame): Call other_buffer_safely instead of
15094 * window.c (temp_output_buffer_show): Call display_buffer with
15095 second argument Vtemp_buffer_show_specifiers and reset latter
15096 immediately after the call.
15097 (Vtemp_buffer_show_specifiers): New variable.
15098 (auto_window_vscroll_p, next_screen_context_lines)
15099 (Vscroll_preserve_screen_position): Remove leading asterisks from
15102 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
15104 Fix minor problems found by GCC 4.6.0 static checking.
15105 * buffer.c (Qclone_number): Remove for now, as it's unused.
15106 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
15107 (record_buffer): Remove unused local.
15108 * frame.c (other_visible_frames, frame_buffer_list): Now static.
15109 (set_frame_buffer_list): Remove; unused.
15110 * frame.h (other_visible_frames): Remove decl.
15111 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
15112 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
15113 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
15115 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
15116 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
15117 Define only if HAVE_GPM.
15118 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
15119 (update_hints_inhibit): Remove; never set. All uses removed.
15120 * widgetprv.h (emacsFrameClassRec): Remove decl.
15121 * window.c (delete_deletable_window): Now returns void, since it
15122 wasn't returning anything.
15123 (compare_window_configurations): Remove unused locals.
15124 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
15125 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
15126 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
15127 the same widths as pointers. This follows up on the 2011-05-06 patch.
15128 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
15129 * xterm.h: Likewise.
15130 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.
15132 2011-06-12 Juanma Barranquero <lekktu@gmail.com>
15134 * makefile.w32-in: Update dependencies.
15135 (LISP_H): Add lib/intprops.h.
15137 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
15139 * image.c (gif_load): Add animation frame delay to the metadata.
15140 (syms_of_image): Use DEFSYM. New symbol `delay'.
15142 2011-06-11 Martin Rudalics <rudalics@gmx.at>
15144 * window.c (delete_deletable_window): Re-add.
15145 (Fset_window_configuration): Rewrite to handle dead buffers and
15146 consequently deletable windows.
15147 (window_tree, Fwindow_tree): Remove. Supply functionality in
15149 (compare_window_configurations): Simplify code.
15151 2011-06-11 Andreas Schwab <schwab@linux-m68k.org>
15153 * image.c (imagemagick_load_image): Fix type mismatch.
15154 (Fimagemagick_types): Likewise.
15156 * window.h (replace_buffer_in_windows): Declare.
15158 2011-06-11 Martin Rudalics <rudalics@gmx.at>
15160 * buffer.c: New Lisp objects Qbuffer_list_update_hook and
15161 Qclone_number. Remove external declaration of Qdelete_window.
15162 (Fbuffer_list): Rewrite doc-string. Minor restructuring of
15164 (Fget_buffer_create, Fmake_indirect_buffer, Frename_buffer):
15165 Run Qbuffer_list_update_hook if allowed.
15166 (Fother_buffer): Rewrite doc-string. Major rewrite for new
15167 buffer list implementation.
15168 (other_buffer_safely): New function.
15169 (Fkill_buffer): Replace call to replace_buffer_in_all_windows by
15170 calls to replace_buffer_in_windows and
15171 replace_buffer_in_windows_safely. Run Qbuffer_list_update_hook
15173 (record_buffer): Inhibit quitting and rewrite using quittable
15174 functions. Run Qbuffer_list_update_hook if allowed.
15175 (Frecord_buffer, Funrecord_buffer): New functions.
15176 (switch_to_buffer_1, Fswitch_to_buffer): Remove.
15177 Move switch-to-buffer to window.el.
15178 (bury-buffer): Move to window.el.
15179 (Vbuffer_list_update_hook): New variable.
15181 * lisp.h (other_buffer_safely): Add prototype in buffer.c
15184 * window.h (resize_frame_windows): Move up in code.
15185 (Fwindow_frame): Remove EXFUN.
15186 (replace_buffer_in_all_windows): Remove prototype.
15187 (replace_buffer_in_windows_safely): Add prototype.
15189 * window.c: Declare Qdelete_window static again. Move down
15190 declaration of select_count.
15191 (Fnext_window, Fprevious_window): Rewrite doc-strings.
15192 (Fother_window): Move to window.el.
15193 (window_loop): Remove DELETE_BUFFER_WINDOWS and UNSHOW_BUFFER
15194 cases. Add REPLACE_BUFFER_IN_WINDOWS_SAFELY case.
15195 (Fdelete_windows_on, Freplace_buffer_in_windows): Move to
15197 (replace_buffer_in_windows): Implement by calling
15198 Qreplace_buffer_in_windows.
15199 (replace_buffer_in_all_windows): Remove with some functionality
15200 moved into replace_buffer_in_windows_safely.
15201 (replace_buffer_in_windows_safely): New function.
15202 (select_window_norecord, select_frame_norecord): Move in front
15203 of run_window_configuration_change_hook. Remove now obsolete
15205 (Fset_window_buffer): Rewrite doc-string.
15206 Call Qrecord_window_buffer.
15207 (keys_of_window): Move binding for other-window to window.el.
15209 2011-06-11 Chong Yidong <cyd@stupidchicken.com>

15655 (single_display_spec_string_p): Support property values that are
15656 lists with the argument STRING its top-level element.
15657 (display_prop_string_p): Fix the condition for processing a
15658 property that is a list to be consistent with handle_display_spec.
15659 (handle_display_spec): New function, refactored from the
15660 last portion of handle_display_prop.
15661 (compute_display_string_pos): Accept additional argument
15662 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
15663 value of a `display' property is a "replacing spec".
15664 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
15665 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
15666 the display property, but just return a value indicating whether
15667 the display property will replace the characters it covers.
15668 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
15669 frame_window_p members of struct bidi_it.
15670 (compute_display_string_pos, compute_display_string_end):
15672 (push_it): Accept second argument POSITION, where pop_it should
15673 jump to continue iteration.
15674 (reseat_1): Initialize bidi_it.disp_pos.
15676 * keyboard.c (adjust_point_for_property): Adjust the call to
15677 display_prop_intangible_p to its new signature.

15682 (compute_display_string_pos, compute_display_string_end):
15683 Declare prototypes.
15684 (struct bidi_it): New members nchars and disp_pos. ch_len is now
15687 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
15689 Malloc failure behavior now depends on size of allocation.
15690 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
15691 * lisp.h: Change signatures accordingly.
15692 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
15693 All callers changed. (Bug#8762)
15695 * gnutls.c: Use Emacs's memory allocators.
15696 Without this change, the gnutls library would invoke malloc etc.
15697 directly, which causes problems on non-SYNC_INPUT hosts, and which
15698 runs afoul of improving memory_full behavior. (Bug#8761)
15699 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
15700 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
15701 xfree instead of the default malloc, realloc, free.
15702 (Fgnutls_boot): No need to check for memory allocation failure,
15703 since xmalloc does that for us.
15705 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
15706 * category.c (hash_get_category_set):
15707 * ccl.c (ccl_driver):
15708 * charset.c (Fdefine_charset_internal):

15720 (Fsxhash, Fgethash, Fputhash, Fmaphash):
15721 * image.c (make_image, search_image_cache, lookup_image)
15722 (xpm_put_color_table_h):
15723 * lisp.h (struct Lisp_Hash_Table):
15724 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
15725 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
15726 for hashes and hash indexes, instead of 'unsigned' and 'int'.
15727 * alloc.c (allocate_vectorlike):
15728 Check for overflow in vector size calculations.
15729 * ccl.c (ccl_driver):
15730 Check for overflow when converting EMACS_INT to int.
15731 * fns.c, image.c: Remove unnecessary static decls that would otherwise
15732 need to be updated by these changes.
15733 * fns.c (make_hash_table, maybe_resize_hash_table):
15734 Check for integer overflow with large hash tables.
15735 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
15736 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
15737 (SXHASH_REDUCE): New macro.
15738 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
15739 Use it instead of discarding useful hash info with large hash values.
15740 (sxhash_float): New function.
15741 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
15742 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
15743 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
15744 Rewrite to use FIXNUM_BITS, as this simplifies things.
15745 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
15746 Adjust signatures to match updated version of code.
15747 (consing_since_gc): Now EMACS_INT, since a single hash table can
15748 use more than INT_MAX bytes.
15750 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
15752 Make it possible to build with GCC-4.6+ -O2 -flto.
15754 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
15756 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
15758 * minibuf.c (get_minibuffer, read_minibuf_unwind):
15759 Call minibuffer-inactive-mode.
15761 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
15763 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
15764 Update dependencies.
15766 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
15768 * data.c (init_data): Remove code for UTS, this system is not
15771 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
15773 Don't force ./temacs to start in terminal mode.
15775 * frame.c (make_initial_frame): Initialize faces in all cases, not
15776 only when CANNOT_DUMP is defined.
15777 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
15779 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
15781 * dispnew.c (add_window_display_history): Use const for the string
15782 pointer. Remove declaration, not needed.
15784 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
15786 Use 'inline', not 'INLINE'.
15787 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
15788 * alloc.c, fontset.c (INLINE): Remove.
15789 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
15790 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
15791 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
15792 * gmalloc.c (register_heapinfo): Use inline unconditionally.
15793 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
15795 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
15797 Make it possible to run ./temacs.
15799 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
15800 syms_of_callproc does the same thing. Remove test for
15801 "initialized", do it in the caller.
15802 * emacs.c (main): Avoid calling set_initial_environment when dumping.
15804 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
15806 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
15807 (read_minibuf): Use get_minibuffer.
15808 (syms_of_minibuf): Use DEFSYM.
15809 (Qmetadata): New var.
15810 * data.c (Qbuffer): Don't make it static.
15811 (syms_of_data): Use DEFSYM.
15813 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
15815 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
15816 (CCL_CODE_MIN): New macro.
15818 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
15820 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
15822 * eval.c (Qdebug): Now static.
15823 * lisp.h (Qdebug): Remove decl. This reverts a part of the
15824 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
15825 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
15827 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
15829 * image.c: Various fixes to ImageMagick code comments.
15830 (Fimagemagick_types): Doc fix.
15832 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
15834 Minor fixes prompted by GCC 4.6.0 warnings.
15836 * xselect.c (converted_selections, conversion_fail_tag): Now static.
15838 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
15839 (x_clipboard_manager_save_all): Move extern decl to ...
15840 * xterm.h: ... here, so that it can be checked for consistency.
15842 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
15844 * xselect.c (x_clipboard_manager_save_frame)
15845 (x_clipboard_manager_save_all): New functions.
15846 (Fx_clipboard_manager_save): Lisp function deleted.
15848 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
15849 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
15851 * xterm.h: Update prototype.
15853 2011-05-28 William Xu <william.xwl@gmail.com>
15855 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
15856 exiting (Bug#8239).
15858 2011-05-28 Jim Meyering <meyering@redhat.com>
15860 Avoid a sign-extension bug in crypto_hash_function.
15861 * fns.c (to_uchar): Define.
15862 (crypto_hash_function): Use it to convert some newly-signed
15863 variables to unsigned, to avoid sign-extension bugs. For example,
15864 without this change, (md5 "truc") would evaluate to
15865 45723a2aff78ff4fff7fff1114760e62 rather than the expected
15866 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
15867 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
15869 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
15871 Integer overflow fixes.
15873 * dbusbind.c: Serial number integer overflow fixes.
15874 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
15875 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
15876 to hold a serial number that is too large for a fixnum.
15877 (Fdbus_method_return_internal, Fdbus_method_error_internal):
15878 Check for serial numbers out of range. Decode any serial number
15879 that was so large that it became a float. (Bug#8722)
15881 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
15882 (Fdbus_call_method, Fdbus_call_method_asynchronously):
15883 Use XFASTINT rather than XUINT when numbers are nonnegative.
15884 (xd_append_arg, Fdbus_method_return_internal):
15885 (Fdbus_method_error_internal): Likewise. Also, for unsigned
15886 arguments, check that Lisp number is nonnegative, rather than
15887 silently wrapping negative numbers around. (Bug#8722)
15888 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
15891 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
15893 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
15895 ccl: Add integer overflow checks.
15896 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
15897 (IN_INT_RANGE): New macros.
15898 (ccl_driver): Use them to check for integer overflow when
15899 decoding a CCL program. Many of the new checks are whether XINT (x)
15900 fits in int; it doesn't always, on 64-bit hosts. The new version
15901 doesn't catch all possible integer overflows, but it's an
15902 improvement. (Bug#8719)
15904 * alloc.c (make_event_array): Use XINT, not XUINT.
15905 There's no need for unsigned here.
15907 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
15908 This follows up to the 2011-05-06 change that substituted uintptr_t
15909 for EMACS_INT. This case wasn't caught back then.
15911 Rework Fformat to avoid integer overflow issues.
15912 * editfns.c: Include <float.h> unconditionally, as it's everywhere
15913 now (part of C89). Include <verify.h>.
15914 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
15915 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
15916 (Fformat): Avoid the prepass trying to compute sizes; it was only
15917 approximate and thus did not catch overflow reliably. Instead, walk
15918 through the format just once, formatting and computing sizes as we go,
15919 checking for integer overflow at every step, and allocating a larger
15920 buffer as needed. Keep track separately whether the format is
15921 multibyte. Keep only the most-recently calculated precision, rather
15922 than them all. Record whether each argument has been converted to
15923 string. Use EMACS_INT, not int, for byte and char and arg counts.
15924 Support field widths and precisions larger than INT_MAX. Avoid
15925 sprintf's undefined behavior with conversion specifications such as %#d
15926 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
15927 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
15928 formatting out-of-range floating point numbers with int
15929 formats. (Bug#8668)
15931 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
15933 * data.c: Avoid integer truncation in expressions involving floats.
15934 * data.c: Include <intprops.h>.
15935 (arith_driver): When there's an integer overflow in an expression
15936 involving floating point, convert the integers to floating point
15937 so that the resulting value does not suffer from catastrophic
15938 integer truncation. For example, on a 64-bit host (* 4
15939 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
15940 Do not rely on undefined behavior after integer overflow.
15942 merge count_size_as_multibyte, parse_str_to_multibyte
15943 * character.c, character.h (count_size_as_multibyte):
15944 Rename from parse_str_to_multibyte; all uses changed.
15945 Check for integer overflow.
15946 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
15947 since it's now a duplicate of the other. This is more of
15948 a character than a buffer op, so better that it's in character.c.
15949 * fns.c, print.c: Adjust to above changes.
15951 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
15953 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
15955 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
15957 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
15958 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
15959 (x_clipboard_manager_save): Now static.
15960 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
15962 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
15963 (crypto_hash_function): Now static.
15964 Fix pointer signedness problems. Avoid unnecessary initializations.
15966 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
15968 * termhooks.h (Vselection_alist): Make it terminal-local.
15970 * terminal.c (create_terminal): Initialize it.
15972 * xselect.c: Support for clipboard managers.
15973 (Vselection_alist): Move to termhooks.h as terminal-local var.
15974 (LOCAL_SELECTION): New macro.
15975 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
15976 (symbol_to_x_atom): Remove gratuitous arg.
15977 (x_handle_selection_request, lisp_data_to_selection_data)
15978 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
15979 (x_own_selection, x_get_local_selection, x_convert_selection):
15980 New arg, specifying work frame. Use terminal-local Vselection_alist.
15981 (some_frame_on_display): Delete unused function.
15982 (Fx_own_selection_internal, Fx_get_selection_internal)
15983 (Fx_disown_selection_internal, Fx_selection_owner_p)
15984 (Fx_selection_exists_p): New optional frame arg.
15985 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
15986 (x_handle_selection_clear): Don't treat other terminals with the
15987 same keyboard specially. Use the terminal-local Vselection_alist.
15988 (x_clear_frame_selections): Use Frun_hook_with_args.
15990 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
15992 * xterm.h: Add support for those atoms.
15994 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
15996 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
15997 (converted_selections, conversion_fail_tag): New global variables.
15998 (x_selection_request_lisp_error): Free the above.
15999 (x_get_local_selection): Remove unnecessary code.
16000 (x_reply_selection_request): Args changed; handle arbitrary array
16001 of converted selections stored in converted_selections.
16002 Separate the XChangeProperty and SelectionNotify steps.
16003 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
16004 (x_convert_selection): New function.
16005 (x_handle_selection_event): Simplify.
16006 (x_get_foreign_selection): Don't ignore incoming requests while
16007 waiting for an answer; this will fail when we implement
16008 SAVE_TARGETS, and seems unnecessary anyway.
16009 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
16010 (Vx_sent_selection_functions): Doc fix.
16012 2011-05-26 Leo Liu <sdl.web@gmail.com>
16014 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
16016 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16018 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
16020 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
16021 for fringe update if it has periodic bitmap.
16022 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
16023 and fringe_bitmap_periodic_p.
16025 * fringe.c (get_fringe_bitmap_data): New function.
16026 (draw_fringe_bitmap_1, update_window_fringes): Use it.
16027 (update_window_fringes): Record periodicity of fringe bitmap in glyph
16028 row. Mark glyph row for fringe update if periodicity changed.
16030 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
16031 for fringe update unless it has periodic bitmap.
16033 2011-05-25 Kenichi Handa <handa@m17n.org>
16035 * xdisp.c (get_next_display_element): Set correct it->face_id for
16036 a static composition.

16050 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
16051 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
16052 Remove macros that are defined and never used.
16053 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
16055 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
16057 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
16058 (Fx_get_selection_internal): Minor cleanup.

16088 * systime.h (Time): Define only if emacs is defined.
16089 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
16090 where the include path doesn't have X11/X.h by default. See
16091 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
16093 2011-05-20 Kenichi Handa <handa@m17n.org>
16095 * composite.c (find_automatic_composition): Fix previous change.
16097 2011-05-20 Glenn Morris <rgm@gnu.org>
16099 * lisp.mk: New file, split from Makefile.in.
16100 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
16101 (shortlisp): Remove.
16102 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
16104 2011-05-19 Glenn Morris <rgm@gnu.org>
16106 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
16107 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
16108 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
16109 (lisp): Set the order to that of loadup.el.
16110 (shortlisp): Make it a copy of $lisp.
16111 (SOME_MACHINE_LISP): Remove.
16112 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
16113 Use just $shortlisp, not $SOME_MACHINE_LISP too.
16115 2011-05-18 Kenichi Handa <handa@m17n.org>
16117 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
16118 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
16119 (find_automatic_composition): Mostly rewrite for efficiency.
16121 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
16123 * makefile.w32-in: Update dependencies.
16125 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
16127 * menu.c: Include limits.h (fixes the MS-Windows build broken by
16128 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
16130 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
16132 Fix some integer overflow issues, such as string length overflow.
16134 * insdel.c (count_size_as_multibyte): Check for string overflow.
16136 * character.c (lisp_string_width): Check for string overflow.
16137 Use EMACS_INT, not int, for string indexes and lengths; in
16138 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
16139 the resulting string length overflows an EMACS_INT; instead,
16140 report a string overflow if no precision given. When checking for
16141 precision exhaustion, use a check that cannot possibly have
16142 integer overflow. (Bug#8675)
16143 * character.h (lisp_string_width): Adjust to new signature.
16145 * alloc.c (string_overflow): New function.
16146 (Fmake_string): Use it. This doesn't change behavior, but saves
16147 a few bytes and will simplify future changes.
16148 * character.c (string_escape_byte8): Likewise.
16149 * lisp.h (string_overflow): New decl.
16151 Fixups, following up to the user-interface timestamp change.
16152 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
16153 for UI timestamps, instead of unsigned long.
16154 * msdos.c (mouse_get_pos): Likewise.
16155 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
16156 * w32gui.h (Time): Define by including "systime.h" rather than by
16157 declaring it ourselves. (Bug#8664)
16159 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
16160 * image.c (clear_image_cache): Likewise.
16162 * term.c (term_mouse_position): Don't assume time_t wraparound.
16164 Be more systematic about user-interface timestamps.
16165 Before, the code sometimes used 'Time', sometimes 'unsigned long',
16166 and sometimes 'EMACS_UINT', to represent these timestamps.
16167 This change causes it to use 'Time' uniformly, as that's what X uses.
16168 This makes the code easier to follow, and makes it easier to catch
16169 integer overflow bugs such as Bug#8664.
16170 * frame.c (Fmouse_position, Fmouse_pixel_position):
16171 Use Time, not unsigned long, for user-interface timestamps.
16172 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
16173 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
16174 * keyboard.h (last_event_timestamp): Likewise.
16175 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
16176 * menu.h (xmenu_show): Likewise.
16177 * term.c (term_mouse_position): Likewise.
16178 * termhooks.h (struct input_event.timestamp): Likewise.
16179 (struct terminal.mouse_position_hook): Likewise.
16180 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
16181 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
16182 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
16183 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
16184 what it was before.
16185 * menu.h, termhooks.h: Include "systime.h", for Time.
16187 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
16188 Don't assume that the difference between two unsigned long values
16189 can fit into an integer. At this point, we know button_down_time
16190 <= event->timestamp, so the difference must be nonnegative, so
16191 there's no need to cast the result if double-click-time is
16192 nonnegative, as it should be; check that it's nonnegative, just in
16193 case. This bug is triggered when events are more than 2**31 ms
16194 apart (about 25 days). (Bug#8664)
16196 * xselect.c (last_event_timestamp): Remove duplicate decl.
16197 (x_own_selection): Remove needless cast to unsigned long.
16199 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
16200 that always fit in int. Use a sentinel instead of a counter, to
16201 avoid a temp and to allay GCC's concerns about possible int overflow.
16202 * frame.h (struct frame): Use int for menu_bar_items_used
16203 instead of EMACS_INT, since it always fits in int.
16205 * menu.c (grow_menu_items): Check for int overflow.
16207 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
16209 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
16210 Before, the code was not consistent. These values cannot exceed
16211 2**31 - 1 so there's no need to make them unsigned.
16212 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
16213 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
16214 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
16216 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
16218 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
16219 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
16220 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
16221 presumably because the widths might not match.
16223 * window.c (size_window): Avoid needless test at loop start.
16225 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
16227 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
16229 2011-05-12 Drew Adams <drew.adams@oracle.com>
16231 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
16233 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16235 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
16236 `width' to `bar_area_x' and `bar_area_width', respectively.
16237 (x_scroll_run): Take account of fringe background extension.
16239 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
16240 Rename local vars `left' and `width' to `bar_area_x' and
16241 `bar_area_width', respectively.
16242 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
16243 background extension.
16245 2011-05-10 Jim Meyering <meyering@redhat.com>
16247 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
16249 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
16251 * image.c (Finit_image_library): Return t for built-in image types,
16252 like pbm and xbm. (Bug#8640)
16254 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
16256 * w32menu.c (set_frame_menubar): Fix submenu allocation.
16258 2011-05-07 Eli Zaretskii <eliz@gnu.org>
16260 * w32console.c (Fset_screen_color): Doc fix.
16261 (Fget_screen_color): New function.
16262 (syms_of_ntterm): Defsubr it.
16264 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
16265 unlink the temporary file if Fcall_process didn't create it in the
16267 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
16268 child process will be redirected to a file specified with `:file'.
16269 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
16270 cue to call_process_cleanup not to close that handle.
16272 2011-05-07 Ben Key <bkey76@gmail.com>
16274 * makefile.w32-in: The bootstrap-temacs rule now makes use of
16275 one of two shell specific rules, either bootstrap-temacs-CMD or
16276 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
16277 to the previous implementation of the bootstrap-temacs rule.
16278 The bootstrap-temacs-CMD rule is similar to the previous
16279 implementation of the bootstrap-temacs rule except that it
16280 makes use of the ESC_CFLAGS variable instead of the CFLAGS
16283 These changes, along with some changes to nt/configure.bat,
16284 nt/gmake.defs, and nt/nmake.defs, are required to extend my
16285 earlier fix to add support for --cflags and --ldflags options
16286 that include quotes so that it works whether make uses cmd or
16289 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
16291 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
16292 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
16294 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
16295 a string. Handle both cases.
16296 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
16297 (Fdbus_register_method): Use Qinvalid_function.
16299 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
16301 * makefile.w32-in: Update dependencies.
16302 (LISP_H): Add inttypes.h and stdin.h.
16303 (PROCESS_H): Add unistd.h.
16305 2011-05-06 Eli Zaretskii <eliz@gnu.org>
16307 * lread.c: Include limits.h (fixes the MS-Windows build broken by
16308 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
16310 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
16312 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
16314 * term.c (vfatal): Remove stray call to va_end.
16315 It's not needed and the C Standard doesn't allow it here anyway.
16317 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
16318 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
16320 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
16323 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
16325 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
16327 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
16329 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
16331 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
16333 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
16334 * charset.c (Fdefine_charset_internal): Don't initialize
16335 charset.code_space[15]. The value was garbage, on hosts with
16336 32-bit int (Bug#8600).
16338 * lread.c (read_integer): Be more consistent with string-to-number.
16339 Use string_to_number to do the actual conversion; this avoids
16340 rounding errors and fixes some other screwups. Without this fix,
16341 for example, #x1fffffffffffffff was misread as -2305843009213693952.
16342 (digit_to_number): Move earlier, for benefit of read_integer.
16343 Return -1 if the digit is out of range for the base, -2 if it is
16344 not a digit in any supported base. (Bug#8602)
16346 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
16348 * dispnew.c (scrolling_window): Return 1 if we scrolled,
16349 to match comment at start of function. This also removes a
16350 GCC warning about overflow in a 32+64-bit port.
16352 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
16354 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
16355 Reported by Stefan Monnier in
16356 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
16357 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
16358 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
16360 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
16361 (EMACS_UINTPTR): Likewise, with uintptr_t.
16363 * lisp.h: Prefer 64-bit EMACS_INT if available.
16364 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
16365 on 32-bit hosts that have 64-bit int, so that they can access
16367 However, temporarily disable this change unless the temporary
16368 symbol WIDE_EMACS_INT is defined.
16370 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
16372 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
16373 This removes an assumption that EMACS_INT and long are the same
16374 width as pointers. The assumption is true for Emacs porting targets
16375 now, but we want to make other targets possible.
16376 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
16377 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
16378 In the rest of the code, change types of integers that hold casted
16379 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
16380 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
16381 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
16382 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
16383 No need to cast type when ORing.
16384 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
16385 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
16386 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
16387 assume EMACS_INT is the same width as char *.
16388 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
16389 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
16390 Remove no-longer-needed casts.
16391 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
16392 (xg_tool_bar_help_callback, xg_make_tool_item):
16393 Use EMACS_INTPTR to hold an integer
16394 that will be cast to void *; this can avoid a GCC warning
16395 if EMACS_INT is not the same width as void *.
16396 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
16397 * xdisp.c (display_echo_area_1, resize_mini_window_1):
16398 (current_message_1, set_message_1):
16399 Use a local to convert to proper width without a cast.
16400 * xmenu.c (dialog_selection_callback): Likewise.
16402 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
16403 Also, don't assume VALBITS / RAND_BITS is less than 5,
16404 and don't rely on undefined behavior when shifting a 1 left into
16406 * lisp.h (get_random): Change signature to match.
16408 * lread.c (hash_string): Use size_t, not int, for hash computation.
16409 Normally we prefer signed values; but hashing is special, because
16410 it's better to use unsigned division on hash table sizes so that
16411 the remainder is nonnegative. Also, size_t is the natural width
16412 for hashing into memory. The previous code used 'int', which doesn't
16413 retain enough info to hash well into very large tables.
16414 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
16416 * dbusbind.c: Don't possibly lose pointer info when converting.
16417 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
16418 Use XPNTR rather than XHASH, so that the high-order bits of
16419 the pointer aren't lost when converting through void *.
16421 * eval.c (Fautoload): Don't double-shift a pointer.
16423 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
16425 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
16427 * gnutls.c (DEF_GNUTLS_FN):
16428 * image.c (DEF_IMGLIB_FN): Make function pointers static.
16430 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
16432 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
16435 2011-05-05 Eli Zaretskii <eliz@gnu.org>
16437 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
16438 New version that can reserve upto 2GB of heap space.
16440 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
16442 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
16444 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
16446 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
16447 `gnutls_certificate_set_x509_key_file'.
16449 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
16451 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
16452 Update dependencies.
16454 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
16456 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
16457 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
16458 Remove unused parameter `fildes'.
16459 * process.c (read_process_output, send_process): Don't pass it.
16461 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
16463 Fix previous change: the library cache is defined in w32.c.
16464 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
16465 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
16467 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
16469 Implement dynamic loading of GnuTLS on Windows.
16471 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
16472 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
16473 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
16476 * gnutls.c (Qgnutls_dll): Define.
16477 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
16478 (gnutls_*): Declare function pointers.
16479 (init_gnutls_functions): New function to initialize function pointers.
16480 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
16481 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
16482 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
16483 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
16484 (emacs_gnutls_write, emacs_gnutls_read)
16485 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
16486 (Fgnutls_available_p): New function.
16487 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
16488 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
16489 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
16491 * image.c: Include w32.h.
16492 (Vimage_type_cache): Delete.
16493 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
16494 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
16495 (w32_delayed_load): Move to w32.c.
16497 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
16499 * w32.c (QCloaded_from, Vlibrary_cache): Define.
16500 (w32_delayed_load): Move from image.c. When loading a library, record
16501 its filename in the :loaded-from property of the library id.
16502 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
16503 Initialize and staticpro them.
16504 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
16506 * process.c: Include lisp.h before w32.h, not after.
16507 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
16508 instead of gnutls_record_check_pending.
16510 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
16512 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
16514 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
16515 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
16518 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
16520 * xterm.c (x_set_frame_alpha): Do not set property on anything

16560 rather than `XVECTOR (FOO)->size'.
16562 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
16563 inttypes.h, as a gnulib replacement is used if it not available in
16566 2011-04-21 Eli Zaretskii <eliz@gnu.org>
16568 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.

16578 charbuf for the composition carryover bytes.
16580 2011-04-21 Eli Zaretskii <eliz@gnu.org>
16582 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
16583 aborting when %lld or %lll format is passed.

16585 %llo or %llx format is passed. (Bug#8545)
16587 * window.c (window_scroll_line_based): Use a marker instead of
16588 simple variables to record original value of point. (Bug#7952)
16590 * doprnt.c (doprnt): Fix the case where a multibyte sequence
16591 produced by %s or %c overflows available buffer space. (Bug#8545)
16593 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
16595 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
16596 (SIZE_MAX): Move defn after all includes, as they might #define it.
16598 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
16600 * w32.c (init_environment): Warn about defaulting HOME to C:\.
16602 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
16604 * keyboard.c (Qdelayed_warnings_hook): Define.
16605 (command_loop_1): Run `delayed-warnings-hook'
16606 if Vdelayed_warnings_list is non-nil.
16607 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
16608 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
16610 2011-04-28 Eli Zaretskii <eliz@gnu.org>
16612 * doprnt.c (doprnt): Don't return value smaller than the buffer
16613 size if the message was truncated. (Bug#8545).
16615 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
16617 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
16618 (Fx_window_property): #if-0 the whole functions, not just the bodies.
16620 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
16622 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
16624 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
16626 * makefile.w32-in: Update dependencies.
16628 2011-04-27 Eli Zaretskii <eliz@gnu.org>
16630 Improve `doprnt' and its usage. (Bug#8545)
16631 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
16632 `format_end'. Remove support for %l as a conversion specifier.
16633 Don't use xrealloc. Improve diagnostics when the %l size modifier
16634 is used. Update the commentary.
16636 * eval.c (verror): Simplify calculation of size_t.
16638 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
16641 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
16643 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
16646 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
16648 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
16649 This makes this file independent of the recent pseudovector change.
16651 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
16653 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
16655 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
16656 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
16657 Remove unused local.
16658 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
16660 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
16661 GCC 4.6.0 optimizes based on type-based alias analysis.
16662 For example, if b is of type struct buffer * and v of type struct
16663 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
16664 != &v->size, and therefore "v->size = 1; b->size = 2; return
16665 v->size;" must therefore return 1. This assumption is incorrect
16666 for Emacs, since it type-puns struct Lisp_Vector * with many other
16667 types. To fix this problem, this patch adds a new type struct
16668 vectorlike_header that documents the constraints on layout of vectors
16669 and pseudovectors, and helps optimizing compilers not get fooled
16670 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
16671 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
16672 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
16674 (XSETPVECTYPE): Rewrite in terms of new macro.
16675 (XSETPVECTYPESIZE): New macro, specifying both type and size.
16676 This is a bit clearer, and further avoids the possibility of
16677 undesirable aliasing.
16678 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
16679 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
16680 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
16681 since Lisp_Subr is a special case (no "next" field).
16682 (ASIZE): Now uses header.size rather than size.
16683 All previous uses of XVECTOR (foo)->size replaced to use this macro,
16684 to avoid the hassle of writing XVECTOR (foo)->header.size.
16685 (struct vectorlike_header): New type.
16686 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
16687 object, to help avoid aliasing.
16688 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
16689 (SUBRP): Likewise, since Lisp_Subr is a special case.
16690 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
16691 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
16692 (struct Lisp_Hash_Table): Combine first two members into a single
16693 struct vectorlike_header member. All uses of "size" and "next" members
16694 changed to be "header.size" and "header.next".
16695 * buffer.h (struct buffer): Likewise.
16696 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
16697 * frame.h (struct frame): Likewise.
16698 * process.h (struct Lisp_Process): Likewise.
16699 * termhooks.h (struct terminal): Likewise.
16700 * window.c (struct save_window_data, struct saved_window): Likewise.
16701 * window.h (struct window): Likewise.
16702 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
16703 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
16704 * buffer.c (init_buffer_once): Likewise.
16705 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
16707 * process.c (Fformat_network_address): Use local var for size,
16710 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
16712 Make the Lisp reader and string-to-float more consistent (Bug#8525)
16713 * data.c (atof): Remove decl; no longer used or needed.
16714 (digit_to_number): Move to lread.c.
16715 (Fstring_to_number): Use new string_to_number function, to be
16716 consistent with how the Lisp reader treats infinities and NaNs.
16717 Do not assume that floating-point numbers represent EMACS_INT
16718 without losing information; this is not true on most 64-bit hosts.
16719 Avoid double-rounding errors, by insisting on integers when
16720 parsing non-base-10 numbers, as the documentation specifies.
16721 * lisp.h (string_to_number): New decl, replacing ...
16722 (isfloat_string): Remove.
16723 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
16724 (read1): Do not accept +. and -. as integers; this
16725 appears to have been a coding error. Similarly, do not accept
16726 strings like +-1e0 as floating point numbers. Do not report
16727 overflow for integer overflows unless the base is not 10 which
16728 means we have no simple and reliable way to continue.
16729 Break out the floating-point parsing into a new
16730 function string_to_number, so that Fstring_to_number parses
16731 floating point numbers consistently with the Lisp reader.
16732 (digit_to_number): Move here from data.c. Make it static inline.
16733 (E_CHAR, EXP_INT): Remove, replacing with ...
16734 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
16735 (string_to_number): New function, replacing isfloat_string.
16736 This function checks for valid syntax and produces the resulting
16737 Lisp float number too. Rework it so that string-to-number
16738 no longer mishandles examples like "1.0e+". Use strtoumax,
16739 so that overflow for non-base-10 numbers is reported only when
16740 there's no portable and simple way to convert to floating point.
16742 * textprop.c (set_text_properties_1): Rewrite for clarity,
16743 and to avoid GCC warning about integer overflow.
16745 * intervals.h (struct interval): Use EMACS_INT for members
16746 where EMACS_UINT might cause problems. See
16747 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
16748 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
16749 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
16751 (offset_intervals): Tell GCC not to worry about length overflow
16752 when negating a negative length.
16754 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
16755 (overrun_check_free): Likewise.
16757 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
16758 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
16761 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
16762 (gnutls_make_error): Rename local to avoid shadowing.
16763 (gnutls_emacs_global_deinit): ifdef out; not used.
16764 (Fgnutls_boot): Use const for pointer to readonly storage.
16765 Comment out unused local. Fix pointer signedness problems.
16767 * lread.c (openp): Don't stuff size_t into an 'int'.
16768 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
16769 about possible signed overflow.
16771 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
16772 (GDK_KEY_g): Don't define if already defined.
16773 (xg_prepare_tooltip): Avoid pointer signedness problem.
16774 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
16776 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
16777 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
16779 * xfns.c (Fx_window_property): Simplify a bit,
16780 to make a bit faster and to avoid GCC 4.6.0 warning.
16781 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
16783 * fns.c (internal_equal): Don't assume size_t fits in int.
16785 * alloc.c (compact_small_strings): Tighten assertion a little.
16787 Replace pEd with more-general pI, and fix some printf arg casts.
16788 * lisp.h (pI): New macro, generalizing old pEd macro to other
16789 conversion specifiers. For example, use "...%"pI"d..." rather
16790 than "...%"pEd"...".
16791 (pEd): Remove. All uses replaced with similar uses of pI.
16792 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
16793 * alloc.c (check_pure_size): Don't overflow by converting size to int.
16794 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
16795 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
16796 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
16797 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
16798 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
16800 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
16801 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
16802 * print.c (safe_debug_print, print_object): Likewise.
16803 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
16805 Use pI instead of if-then-else-abort. Use %p to avoid casts,
16806 avoiding the 0 flag, which is not portable.
16807 * process.c (Fmake_network_process): Use pI to avoid cast.
16808 * region-cache.c (pp_cache): Likewise.
16809 * xdisp.c (decode_mode_spec): Likewise.
16810 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
16811 behavior on 64-bit hosts with printf arg.
16812 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
16813 (x_stop_queuing_selection_requests): Likewise.
16814 (x_get_window_property): Don't truncate byte count to an 'int'
16817 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
16818 here, since it parses constructs like leading '-' and spaces,
16819 which are not wanted; and it overflows with large numbers.
16820 Instead, simply match F[0-9]+, which is what is wanted anyway.
16822 * alloc.c: Remove unportable assumptions about struct layout.
16823 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
16824 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
16825 (allocate_vectorlike, make_pure_vector): Use the new macros,
16826 plus offsetof, to remove unportable assumptions about struct layout.
16827 These assumptions hold on all porting targets that I know of, but
16828 they are not guaranteed, they're easy to remove, and removing them
16829 makes further changes easier.
16831 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
16832 This doesn't fix a bug but makes the code clearer.
16833 (string_overrun_cookie): Now const. Use initializers that
16834 don't formally overflow signed char, to avoid warnings.
16835 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
16836 can cause Emacs to crash when string overrun checking is enabled.
16837 (allocate_buffer): Don't assume sizeof (struct buffer) is a
16838 multiple of sizeof (EMACS_INT); it need not be, if
16839 alignof(EMACS_INT) < sizeof (EMACS_INT).
16840 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
16842 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
16844 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
16846 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
16848 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
16849 supposed to be handshaking. (Bug#8556)
16850 Reported by Paul Eggert <eggert@cs.ucla.edu>.
16852 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
16854 * lisp.h (Qdebug): List symbol.
16855 * eval.c (Qdebug): Restore global linkage.
16856 * keyboard.c (debug-on-event): New variable.
16857 (handle_user_signal): Break into debugger when debug-on-event
16858 matches the current signal symbol.
16860 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
16862 * alloc.c (check_sblock, check_string_bytes)
16863 (check_string_free_list): Convert to standard C.
16865 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
16867 * w32.c (emacs_gnutls_push): Fix typo.
16869 2011-04-25 Eli Zaretskii <eliz@gnu.org>
16871 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
16872 "cast to pointer from integer of different size".
16874 Improve doprnt and its use in verror. (Bug#8545)
16875 * doprnt.c (doprnt): Document the set of format control sequences
16876 supported by the function. Use SAFE_ALLOCA instead of always
16879 * eval.c (verror): Don't limit the buffer size at size_max-1, that
16880 is one byte too soon. Don't use xrealloc; instead xfree and
16883 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
16885 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
16888 * gnutls.c: Renamed global_initialized to
16889 gnutls_global_initialized. Added internals for the
16890 :verify-hostname-error, :verify-error, and :verify-flags
16891 parameters of `gnutls-boot' and documented those parameters in the
16892 docstring. Start callback support.
16893 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
16894 unless a fatal error occurred. Call gnutls_alert_send_appropriate
16895 on error. Return error code.
16896 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
16897 (emacs_gnutls_read): Likewise.
16898 (Fgnutls_boot): Return handshake error code.
16899 (emacs_gnutls_handle_error): New function.
16900 (wsaerror_to_errno): Likewise.
16902 * w32.h (emacs_gnutls_pull): Add prototype.
16903 (emacs_gnutls_push): Likewise.
16905 * w32.c (emacs_gnutls_pull): New function for GnuTLS on Woe32.
16906 (emacs_gnutls_push): Likewise.
16908 2011-04-24 Claudio Bley <claudio.bley@gmail.com> (tiny change)
16910 * process.c (wait_reading_process_output): Check if GnuTLS
16911 buffered some data internally if no FDs are set for TLS
16914 * makefile.w32-in (OBJ2): Add gnutls.$(O).
16915 (LIBS): Link to USER_LIBS.

16920 * xdisp.c (handle_single_display_spec): Rename the
16921 display_replaced_before_p argument into display_replaced_p, to
16922 make it consistent with the commentary. Fix typos in the
16925 * textprop.c (syms_of_textprop): Remove dead code.
16926 (copy_text_properties): Delete obsolete commentary about an
16927 interface that was deleted long ago. Fix typos in the description

16931 to changes in oldXMenu/XMenu.h from 2011-04-16.
16932 <menu_help_message, prev_menu_help_message>: Constify.
16933 (IT_menu_make_room): menu->help_text is now `const char **';

17009 FINAL_CHAR is a character, and use %c when it is passed as
17010 argument to `error'.
17012 2011-04-23 Eli Zaretskii <eliz@gnu.org>
17014 * s/ms-w32.h (localtime): Redirect to sys_localtime.

17200 ns_descriptor_to_entity that were caused by using free to
17201 deallocate memory blocks that were allocated by xmalloc (via

17222 (emacs_read, emacs_write): Use it.
17223 * process.c (send_process): Adjust to the new signatures of
17224 emacs_write and emacs_gnutls_write. Do not attempt to store

17417 * font.c (font_close_object): Now static.
17418 * font.h (font_close_object): Remove.
17419 * fontset.c (FONTSET_OBJLIST): Remove.
17420 (free_realized_fontset) #if-0 the body, which does nothing.
17421 (face_suitable_for_char_p): #if-0, as it's never called.
17422 * fontset.h (face_suitable_for_char_p): Remove decl.
17423 * xfaces.c (face_at_string_position):
17424 Use FACE_SUITABLE_FOR_ASCII_CHAR_P, not FACE_SUITABLE_FOR_CHAR_P,
17425 since 0 is always ASCII.
17427 * fns.c (weak_hash_tables): Now static.
17429 * fileio.c: Make symbols static if they're not exported.

17448 * editfns.c, lisp.h (get_operating_system_release): Remove.
17449 * process.c (init_process) [DARWIN_OS]: Do it inline, as it is not
17450 worth the hassle of breaking this out.
17452 * xterm.c: Make symbols static if they're not exported.
17453 (x_raise_frame, x_lower_frame, x_wm_set_window_state):
17454 (x_wm_set_icon_pixmap, x_initialize, XTread_socket_fake_io_error):

17556 * buffer.c (buffer_count): Remove unused var.

17565 * atimer.h (run_all_atimers): Remove; not exported.
17567 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
17568 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
17569 was inaccessible from Lisp.
17570 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
17571 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
17573 alloc.c: Import and export fewer symbols, and remove unused items.
17574 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
17576 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
17577 it's not optimized away by whole-program optimization.

17579 (catchlist, handlerlist, mark_backtrace):
17580 Declare only if BYTE_MARK_STACK.

17589 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
17590 (mark_backtrace): Define only if BYTE_MARK_STACK.
17591 * xdisp.c (message_enable_multibyte): Now static.
17593 Declare Lisp_Object Q* variables to be 'static' if not exported.
17594 This makes it easier for human readers (and static analyzers)
17595 to see whether these variables are used from other modules.
17596 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
17597 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:

17606 Remove decls of unexported vars.
17607 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
17609 * lisp.h (DEFINE_FUNC): Make sname 'static'.
17611 Make Emacs functions such as Fatom 'static' by default.
17612 This makes it easier for human readers (and static analyzers)
17613 to see whether these functions can be called from other modules.
17614 DEFUN now defines a static function. To make the function external
17615 so that it can be used in other C modules, use the new macro DEFUE.
17616 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
17617 (Finit_image_library):
17618 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
17619 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
17620 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
17621 Remove decls, since these functions are now static.
17622 (Funintern, Fget_internal_run_time): New decls, since these functions
17623 were already external.
17625 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
17626 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

17632 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
17633 Mark functions with DEFUE instead of DEFUN,
17634 if they are used in other modules.
17635 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
17636 decls for now-static functions.
17637 * buffer.h (Fdelete_overlay): Remove decl.
17638 * callproc.c (Fgetenv_internal): Mark as internal.

17647 * image.c (Finit_image_library): New forward static decl.
17648 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
17649 * intervals.h (Fprevious_property_change):
17650 (Fremove_list_of_text_properties): Remove decls.
17651 * keyboard.c (Fthis_command_keys): Remove decl.
17652 (Fcommand_execute): New forward static decl.

17668 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
17670 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
17673 2011-04-13 Eli Zaretskii <eliz@gnu.org>
17675 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
17676 when at ZV. (Bug#8487)
17678 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
17680 * charset.c (Fclear_charset_maps): Use xfree instead of free.
17682 * keyboard.c (parse_tool_bar_item): Likewise.
17683 * sound.c (sound_cleanup, alsa_close): Likewise.
17684 * termcap.c (tgetent): Likewise.

17686 * xsettings.c (read_and_apply_settings): Likewise.
17688 * alloc.c (overrun_check_malloc, overrun_check_realloc)
17689 (overrun_check_free): Protoize.
17691 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
17693 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
17694 since callers should never pass a negative size.
17695 Change the signature to match that of plain 'read' and 'write'; see
17696 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
17697 * lisp.h: Update prototypes of emacs_write and emacs_read.
17699 2011-04-11 Eli Zaretskii <eliz@gnu.org>
17701 * xdisp.c (redisplay_window): Don't try to determine the character
17702 position of the scroll margin if the window start point w->startp
17703 is outside the buffer's accessible region. (Bug#8468)
17705 2011-04-10 Eli Zaretskii <eliz@gnu.org>
17707 Fix write-region and its subroutines for buffers > 2GB.
17708 * fileio.c (a_write, e_write): Modify declaration of arguments and
17709 local variables to support buffers larger than 2GB.
17710 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
17712 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
17713 argument, local variables, and return value.
17715 * lisp.h: Update prototypes of emacs_write and emacs_read.
17717 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
17719 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
17721 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
17723 Fix more problems found by GCC 4.6.0's static checks.
17725 * xdisp.c (vmessage): Use a better test for character truncation.
17727 * charset.c (load_charset_map): <, not <=, for optimization,
17728 and to avoid potential problems with integer overflow.
17729 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
17730 * casetab.c (set_identity, shuffle): Likewise.
17731 * editfns.c (Fformat): Likewise.
17732 * syntax.c (skip_chars): Likewise.
17734 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
17735 This also lets GCC 4.6.0 generate slightly better loop code.
17737 * callint.c (Fcall_interactively): <, not <=, for optimization.
17738 (Fcall_interactively): Count the number of arguments produced,
17739 not the number of arguments given. This is simpler and lets GCC
17740 4.6.0 generate slightly better code.
17742 * ftfont.c: Distingish more carefully between FcChar8 and char.
17743 The previous code passed unsigned char * to a functions like
17744 strlen and xstrcasecmp that expect char *, which does not
17745 conform to the C standard.
17746 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
17747 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
17748 char * when the C standard requires it.
17750 * keyboard.c (read_char): Remove unused var.
17752 * eval.c: Port to Windows vsnprintf (Bug#8435).
17753 Include <limits.h>.
17754 (SIZE_MAX): Define if the headers do not.
17755 (verror): Do not give up if vsnprintf returns a negative count.
17756 Instead, grow the buffer. This ports to Windows vsnprintf, which
17757 does not conform to C99. Problem reported by Eli Zaretskii.
17758 Also, simplify the allocation scheme, by avoiding the need for
17759 calling realloc, and removing the ALLOCATED variable.
17761 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
17763 Remove invocations of doprnt, as Emacs now uses vsnprintf.
17764 But keep the doprint source code for now, as we might revamp it
17765 and use it again (Bug#8435).
17766 * lisp.h (doprnt): Remove.
17767 * Makefile.in (base_obj): Remove doprnt.o.
17768 * deps.mk (doprnt.o): Remove.
17770 error: Print 32- and 64-bit integers portably (Bug#8435).
17771 Without this change, on typical 64-bit hosts error ("...%d...", N)
17772 was used to print both 32- and 64-bit integers N, which relied on
17773 undefined behavior.
17774 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
17775 * lisp.h (error, verror): Mark as printf-like functions.
17776 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
17777 Report overflow in size calculations when allocating printf buffer.
17778 Do not truncate output string at its first null byte.
17779 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
17780 Truncate the output at a character boundary, since vsnprintf does not
17782 * charset.c (check_iso_charset_parameter): Convert internal
17783 character to string before calling 'error', since %c now has the
17785 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
17786 overflow when computing char to be passed to 'error'. Do not
17787 pass Lisp_Object to 'error'; pass the integer instead.
17788 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
17789 formatted with plain %d.
17791 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
17793 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
17795 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
17797 * xterm.c (x_catch_errors): Remove duplicate declaration.
17799 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
17801 * xdisp.c, lisp.h (message_nolog): Remove; unused.
17803 2011-04-10 Jim Meyering <meyering@redhat.com>
17805 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
17806 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
17807 return ssize_t not "int", and use size_t as the buffer length.
17808 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
17809 * gnutls.h: Update declarations.
17810 * process.c (read_process_output): Use ssize_t, to match.
17811 (send_process): Likewise.
17813 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
17815 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
17817 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
17819 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):

17827 2011-04-09 Eli Zaretskii <eliz@gnu.org>
17829 Fix some uses of `int' instead of EMACS_INT.
17830 * search.c (string_match_1, fast_string_match)
17831 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
17832 (scan_buffer, find_next_newline_no_quit)

17884 (Qhelp_form_show): New var.
17885 (syms_of_keyboard): Use DEFSYM macro.
17887 * print.c (internal_with_output_to_temp_buffer): Function deleted.

17923 * eval.c (Fsignal): Remove excess argument to 'fatal'.
17925 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
17926 This avoids several warnings with gcc -Wstrict-overflow.
17927 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
17928 directly, rather than having caller test rule sign. This avoids
17929 some unnecessary tests.
17930 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
17931 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
17932 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
17934 * xfont.c (xfont_text_extents): Remove var that was set but not used.
17935 (xfont_open): Avoid unnecessary tests.
17937 * composite.c (composition_gstring_put_cache): Use unsigned integer.
17939 * composite.h, composite.c (composition_gstring_put_cache):
17940 Use EMACS_INT, not int, for length.
17942 * composite.h (COMPOSITION_DECODE_REFS): New macro,
17943 breaking out part of COMPOSITION_DECODE_RULE.
17944 (COMPOSITION_DECODE_RULE): Use it.
17945 * composite.c (get_composition_id): Remove unused local vars,
17946 by using the new macro.
17948 * textprop.c (set_text_properties_1): Change while to do-while,
17949 since the condition is always true at first.
17951 * intervals.c (graft_intervals_into_buffer): Mark var as used.
17952 (interval_deletion_adjustment): Return unsigned value.
17955 * process.c (list_processes_1, create_pty, read_process_output):
17956 (exec_sentinel): Remove vars that were set but not used.
17957 (create_pty): Remove unnecessary "volatile"s.
17958 (Fnetwork_interface_info): Avoid possibility of int overflow.

17971 * print.c (print_error_message): Avoid int overflow.
17973 * font.c (font_list_entities): Redo for clarity,
17974 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
17976 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
17977 (font_score): Avoid potential overflow in diff calculation.

17982 * eval.c (funcall_lambda): Rename local to avoid shadowing.
17984 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
17985 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
17986 can always succeed if overflow has undefined behavior.
17988 * search.c (boyer_moore, wordify): Remove vars set but not used.
17989 (wordify): Omit three unnecessary tests.
17991 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.

18000 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
18001 (Finsert_file_contents): Remove unnecessary code checking fd.
18003 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
18004 Check for integer overflow on size calculations.
18006 * buffer.c (Fprevious_overlay_change): Remove var that is set
18009 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
18010 Remove vars that are set but not used.
18011 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
18012 (timer_check_2): Mark vars as initialized.
18014 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
18016 * image.c (lookup_image): Remove var that is set but not used.
18017 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
18019 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
18020 that are set but not used.
18022 * xfns.c (make_invisible_cursor): Don't return garbage
18023 if XCreateBitmapFromData fails (Bug#8410).
18025 * xselect.c (x_get_local_selection, x_handle_property_notify):
18026 Remove vars that are set but not used.
18028 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
18029 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
18031 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
18032 Remove var that is set but not used.
18033 (scroll_bar_windows_size): Now size_t, not int.
18034 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
18035 Check for overflow.
18037 * xfaces.c (realize_named_face): Remove vars that are set but not used.
18038 (map_tty_color) [!defined MSDOS]: Likewise.
18040 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
18042 * coding.c: Remove vars that are set but not used.
18043 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
18044 All callers changed.
18045 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
18046 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
18047 (decode_coding_charset): Remove vars that are set but not used.
18049 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
18050 that is set but not used.
18052 * print.c (print_object): Remove var that is set but not used.
18054 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
18055 The gnulib version avoids calling malloc in the usual case,
18056 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
18057 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
18058 * filelock.c (current_lock_owner): Likewise.
18059 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
18060 * sysdep.c: Include allocator.h, careadlinkat.h.
18061 (emacs_no_realloc_allocator): New static constant.
18062 (emacs_readlink): New function.
18063 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
18064 ../lib/careadlinkat.h.
18066 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
18068 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
18069 first non-nil return value).

18073 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
18074 if not defined (Bug#8403).
18076 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
18078 * xdisp.c (display_count_lines): Remove parameter `start',
18079 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
18080 (get_char_face_and_encoding): Remove parameter `multibyte_p',
18081 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

18083 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
18084 and thereabouts. All callers changed.
18085 (get_per_char_metric): Remove parameter `f', unused since
18086 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
18088 2011-04-02 Jim Meyering <meyering@redhat.com>
18090 do not dereference NULL upon failed strdup
18091 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
18092 (ns_get_family): Likewise.
18094 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
18096 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
18098 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
18100 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
18103 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
18105 Add lexical binding.
18107 * window.c (Ftemp_output_buffer_show): New fun.
18108 (Fsave_window_excursion):
18109 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
18111 * lread.c (lisp_file_lexically_bound_p): New function.
18112 (Fload): Bind Qlexical_binding.
18113 (readevalloop): Remove `evalfun' arg.
18114 Bind Qinternal_interpreter_environment.
18115 (Feval_buffer): Bind Qlexical_binding.
18116 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
18118 (syms_of_lread): Declare `lexical-binding'.
18120 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
18122 * keyboard.c (eval_dyn): New fun.
18123 (menu_item_eval_property): Use it.
18125 * image.c (parse_image_spec): Use Ffunctionp.
18127 * fns.c (concat, mapcar1): Accept byte-code-functions.
18129 * eval.c (Fsetq): Handle lexical vars.
18130 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
18131 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
18132 (FletX, Flet): Obey lexical binding.
18133 (Fcommandp): Handle closures.
18134 (Feval): New `lexical' arg.
18135 (eval_sub): New function extracted from Feval. Use it almost
18136 everywhere where Feval was used. Look up vars in lexical env.
18138 (Ffunctionp): Move from subr.el.
18139 (Ffuncall): Handle closures.
18140 (apply_lambda): Remove `eval_flags'.
18141 (funcall_lambda): Handle closures and new byte-code-functions.
18142 (Fspecial_variable_p): New function.
18143 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
18144 but without exporting it to Lisp.
18146 * doc.c (Fdocumentation, store_function_docstring):
18147 * data.c (Finteractive_form): Handle closures.
18149 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
18152 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
18154 (exec_byte_code): New function extracted from Fbyte_code to handle new
18155 calling convention for byte-code-functions. Add new byte-codes.
18157 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
18159 * alloc.c (Fmake_symbol): Init new `declared_special' field.
18161 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
18163 * xdisp.c (redisplay_internal): Fix prototype.
18165 2011-03-31 Eli Zaretskii <eliz@gnu.org>
18167 * xdisp.c (SCROLL_LIMIT): New macro.
18168 (try_scrolling): Use it when setting scroll_limit.
18169 Limit scrolling to 100 screen lines.
18170 (redisplay_window): Even when falling back on "recentering",
18171 position point in the window according to scroll-conservatively,
18172 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
18174 (try_scrolling): When point is above the window, allow searching
18175 as far as scroll_max, or one screenful, to compute vertical
18176 distance from PT to the scroll margin position. This prevents
18177 try_scrolling from unnecessarily failing when
18178 scroll-conservatively is set to a value slightly larger than the
18179 window height. Clean up the case of PT below the margin at bottom
18180 of window: scroll_max can no longer be INT_MAX. When aggressive
18181 scrolling is in use, don't let point enter the opposite scroll
18182 margin as result of the scroll.
18183 (syms_of_xdisp) <scroll-conservatively>: Document the
18184 threshold of 100 lines for never-recentering scrolling.
18186 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
18188 * dispextern.h (move_it_by_lines):
18189 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused

18191 (message_log_check_duplicate): Remove parameters `prev_bol' and
18192 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
18193 (redisplay_internal): Remove parameter `preserve_echo_area',
18194 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
18196 * indent.c (Fvertical_motion):
18197 * window.c (window_scroll_pixel_based, Frecenter):
18198 Don't pass `need_y_p' to `move_it_by_lines'.
18200 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
18202 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
18203 steal a few bits to be more compact.
18204 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
18205 Remove unneeded casts.
18207 * bytecode.c (Fbyte_code): CAR and CDR can GC.
18209 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
18211 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
18212 binding" message (bug#7967).
18214 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
18216 Fix more problems found by GCC 4.6.0's static checks.
18218 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
18219 Remove unused local var.
18221 * editfns.c (Fmessage_box): Remove unused local var.
18223 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
18224 (note_mode_line_or_margin_highlight, note_mouse_highlight):
18225 Omit unused local vars.
18226 * window.c (shrink_windows): Omit unused local var.
18227 * menu.c (digest_single_submenu): Omit unused local var.
18228 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
18229 Omit unused local var.
18231 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
18232 Don't assume string length fits in int.
18233 (keyremap_step, read_key_sequence): Use size_t for sizes.
18234 (read_key_sequence): Don't check last_real_key_start redundantly.
18236 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
18237 instead of alloca (Bug#8344).
18239 * eval.c (Fbacktrace): Don't assume nargs fits in int.
18240 (Fbacktrace_frame): Don't assume nframes fits in int.
18242 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
18244 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
18247 * term.c (produce_glyphless_glyph): Remove unnecessary test.
18249 * cm.c (calccost): Turn while-do into do-while, for clarity.
18251 * keyboard.c (syms_of_keyboard): Use the same style as later
18252 in this function when indexing through an array. This also
18253 works around GCC bug 48267.
18255 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
18257 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
18259 * chartab.c (sub_char_table_ref_and_range): Redo for slight
18260 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
18262 * keyboard.c, keyboard.h (num_input_events): Now size_t.
18263 This avoids undefined behavior on integer overflow, and is a bit
18264 more convenient anyway since it is compared to a size_t variable.
18266 Variadic C functions now count arguments with size_t, not int.
18267 This avoids an unnecessary limitation on 64-bit machines, which
18268 caused (substring ...) to crash on large vectors (Bug#8344).
18269 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
18270 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
18271 All variadic functions and their callers changed accordingly.
18272 (struct gcpro.nvars): Now size_t, not int. All uses changed.

18491 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
18493 (command_loop_1): Use Frun_hooks. Call safe_run_hooks

18496 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
18498 Fix more problems found by GCC 4.5.2's static checks.
18500 * coding.c (encode_coding_raw_text): Avoid unnecessary test
18501 the first time through the loop, since we know p0 < p1 then.
18502 This also avoids a gcc -Wstrict-overflow warning.
18504 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
18505 leading to a memory leak, possible in functions like
18506 load_charset_map_from_file that can allocate an unbounded number
18507 of objects (Bug#8318).
18509 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
18510 that could (at least in theory) be that large.
18512 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
18513 This is less likely to overflow, and avoids undefined behavior if
18514 overflow does occur. All callers changed. Use strtoul to scan

18532 * process.c (Fmake_network_process): Use socklen_t, not int,
18533 where POSIX says socklen_t is required in portable programs.
18534 This fixes a porting bug on hosts like 64-bit HP-UX, where
18535 socklen_t is wider than int (Bug#8277).
18536 (Fmake_network_process, server_accept_connection):
18537 (wait_reading_process_output, read_process_output):
18540 * process.c: Rename or move locals to avoid shadowing.

18552 Include tparam.h instead, since it declares them.
18553 * cm.h (PC): Remove extern decl; tparam.h now does this.
18554 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
18555 * terminfo.c: Include tparam.h, to check interfaces.
18556 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
18557 (tparam): Adjust signature to match interface in tparam.h;
18558 this removes some undefined behavior. Check that outstring and len
18559 are zero, which they always are with Emacs.
18560 * tparam.h (PC, BC, UP): New extern decls.
18562 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
18563 (xftfont_open): Rename locals to avoid shadowing.

18603 (alsa_choose_format): Remove unused local var.
18604 (wav_play): Initialize a variable to 0, to prevent undefined
18605 behavior (Bug#8278).
18607 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
18609 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
18611 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
18612 clobbering (Bug#8298).
18613 * sysdep.c (sys_subshell): Likewise.
18614 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
18616 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
18617 This should get cleaned up, so that child_setup has the
18618 same signature on all platforms.
18620 * callproc.c (call_process_cleanup): Now static.
18621 (relocate_fd): Rename locals to avoid shadowing.
18623 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
18625 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
18626 not to be necessary, and produces flickering.
18628 2011-03-20 Glenn Morris <rgm@gnu.org>
18630 * config.in: Remove file.
18632 2011-03-20 Juanma Barranquero <lekktu@gmail.com>

18677 Define only if needed.
18679 * unexelf.c (unexec): Name an expression,
18680 to avoid gcc -Wbad-function-cast warning.
18681 Use a different way to cause a compilation error if anyone uses
18682 n rather than nn, a way that does not involve shadowing.
18683 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
18685 * deps.mk (unexalpha.o): Remove; unused.

18742 * callint.c (quotify_arg, quotify_args): Now static.
18743 (Fcall_interactively): Rename locals to avoid shadowing.

18750 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
18751 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
18752 some of which prompt warnings from gcc -Wbad-function-cast.
18753 (Fformat_time_string, Fencode_time, Finsert_char):
18754 (Ftranslate_region_internal, Fformat):

18782 (Fmemory_limit): Cast sbrk's returned value to char *.
18784 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
18785 avoids undefined behavior in theory.
18787 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
18789 Use functions, not macros, for up- and down-casing (Bug#8254).
18790 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
18791 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
18792 to use the following functions instead of these macros.
18793 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
18794 EMACS_INT, since callers assume the returned value fits in int.
18795 (upcase1): Likewise, for UPCASE_TABLE.
18796 (uppercasep, lowercasep, upcase): New static inline functions.
18797 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

18807 (regex_compile, re_match_2_internal): Mark locals as initialized.
18808 (RETALLOC_IF): Define only if needed.
18809 (WORDCHAR_P): Likewise. This one is never needed, but is used
18810 only in a comment talking about a compiler bug, so put inside
18811 the #if 0 of that comment.
18812 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
18813 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

18839 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
18840 New macros, so that the caller can use some names other than
18841 gcpro1, gcpro2, etc.
18842 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
18844 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
18845 argument, for consistency with GCPRO2_VAR, etc: it is now the
18846 prefix of the variable, not the variable itself. All uses
18848 * dired.c (directory_files_internal, file_name_completion):
18849 Rename locals to avoid shadowing.
18851 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
18852 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
18853 dired.c's scmp function, had undefined behavior.
18854 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
18855 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
18856 * buffer.h: ... to here, because these macros use current_buffer,
18857 and the new implementation with inline functions needs to have
18858 current_buffer in scope now, rather than later when the macros
18860 (downcase, upcase1): New static inline functions.
18861 (DOWNCASE, UPCASE1): Reimplement using these functions.
18862 This avoids undefined behavior in expressions like
18863 DOWNCASE (x) == DOWNCASE (y), which previously suffered
18864 from race conditions in accessing the global variables
18865 case_temp1 and case_temp2.
18866 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
18867 * lisp.h (case_temp1, case_temp2): Remove their decls.
18868 * character.h (ASCII_CHAR_P): Move from here ...
18869 * lisp.h: ... to here, so that the inline functions mentioned
18870 above can use them.
18872 * dired.c (directory_files_internal_unwind): Now static.
18874 * fileio.c (file_name_as_directory, directory_file_name):

18877 (file_name_as_directory): Use const pointers when appropriate.
18878 (Fexpand_file_name): Likewise. In particular, newdir might
18879 point at constant storage, so make it a const pointer.
18880 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
18881 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
18883 (Fset_file_times, Finsert_file_contents, auto_save_error):

18888 to avoid shadowing.
18890 * marker.c (bytepos_to_charpos): Remove; unused.
18892 * lisp.h (verify_bytepos, count_markers): New decls,
18893 so that gcc does not warn that these functions aren't declared.
18895 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
18896 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
18897 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
18898 (copy_text): Remove unused local var.

18901 (lock_file_1): Rename local to avoid shadowing.
18903 * buffer.c (fix_overlays_before): Mark locals as initialized.
18904 (fix_start_end_in_overlays): Likewise. This function should be
18905 simplified by using pointers-to-pointers, but that's a different
18907 (switch_to_buffer_1): Now static.
18908 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
18909 (report_overlay_modification): Rename locals to avoid shadowing.

18914 to suppress a gcc -Wclobbered warning that does not seem to be right.
18915 (MAXPATHLEN): Define only if needed.
18917 * process.c (serial_open, serial_configure): Move decls from here ...
18918 * systty.h: ... to here, so that they can be checked.
18920 * fns.c (get_random, seed_random): Move extern decls from here ...
18921 * lisp.h: ... to here, so that they can be checked.
18923 * sysdep.c (reset_io): Now static.

19083 1152921504606846976) returns the obviously-bogus value (-948597
19084 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
19085 reports time overflow. See
