3 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
4 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
5 dostounix_filename. Prevents crashes down the road, because
6 dostounix_filename assumes it gets a unibyte string. Reported by
7 Michel de Ruiter <michel@sentient.nl>, see
8 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html
10 2012-11-17 Eli Zaretskii <eliz@gnu.org>
12 * w32select.c: Include w32common.h before w32term.h, so that
13 windows.h gets included before w32term.h uses some of its
16 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]: New
18 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]: New
20 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
22 2012-11-17 Jan Djärv <jan.h.d@swipnet.se>
24 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
25 (ns_select): Return at once if events are held (Bug#12834).
27 2012-11-16 enami tsugutomo <tsugutomo.enami@jp.sony.com>
29 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
30 Needed following 2012-10-20 change. (Bug#12902)
32 2012-11-16 Glenn Morris <rgm@gnu.org>
34 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
36 2012-11-15 Stefan Monnier <monnier@iro.umontreal.ca>
38 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
40 2012-11-14 Eli Zaretskii <eliz@gnu.org>
42 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
43 use the same value of thread handle.
44 (start_timer_thread): If the timer thread exited (due to error),
45 clean up by closing the two handles it used. Duplicate the caller
46 thread's handle here, so it gets duplicated only once, when
47 launching the timer thread. Set priority of the timer thread, not
49 (getitimer): Don't duplicate the caller thread's handle here.
52 2012-11-13 Jan Djärv <jan.h.d@swipnet.se>
54 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
57 2012-11-12 Eli Zaretskii <eliz@gnu.org>
59 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
60 passed to pint2str and pint2hrstr to be at most the size of the
61 frame's decode_mode_spec_buffer. This avoids crashes with very
62 large values of FIELD_WIDTH argument to decode_mode_spec.
65 2012-11-07 Martin Rudalics <rudalics@gmx.at>
67 * window.c (Fsplit_window_internal): Set combination limit of
68 new parent window to t iff Vwindow_combination_limit is t;
69 fixing a regression introduced with the change from 2012-09-22.
70 (Fwindow_combination_limit, Fset_window_combination_limit):
73 2012-11-06 Eli Zaretskii <eliz@gnu.org>
75 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
76 amount when the scroll margins are too large. When scrolling
77 backwards in the buffer, give up if cannot reach point or the
78 scroll margin within a reasonable number of screen lines.
79 Fixes point position in window under scroll-up/down-aggressively when
80 point is positioned many lines beyond the window top/bottom.
83 2012-11-05 Eli Zaretskii <eliz@gnu.org>
85 * ralloc.c (relinquish): If real_morecore fails to return memory
86 to the system, don't crash; instead, leave the last heap
87 unchanged and return. (Bug#12774)
89 2012-11-03 Eli Zaretskii <eliz@gnu.org>
91 * lisp.mk: Adjust comments to the fact that term/internal is now
92 loaded from loadup.el.
94 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
95 (msdos_fatal_signal): New function.
96 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
99 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
100 for GCC versions before 4.
101 (emacs_raise): Define to call msdos_fatal_signal.
103 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
104 iterator when starting in the middle of a display or overlay
107 2012-11-03 Jan Djärv <jan.h.d@swipnet.se>
109 * widget.c (resize_cb): New function.
110 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
111 (EmacsFrameResize): Check if all is up to date before changing frame
114 2012-11-01 Eli Zaretskii <eliz@gnu.org>
116 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
118 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
120 Fix crash when using Emacs as commit editor for git (Bug#12697).
121 * callproc.c (setpgrp): Remove macro, as we now use setpgid
122 and it is configured in conf_post.h.
123 (Fcall_process): Don't invoke both setsid and setpgid; the former
124 is enough, if it exists.
125 * callproc.c (Fcall_process, child_setup):
126 * process.c (create_process): Use setpgid.
127 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
129 * dispnew.c (init_display): Initialize the foreground group
130 if we are running a tty display.
131 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
132 * lisp.h (init_foreground_group): New decl.
133 * sysdep.c (inherited_pgroup): New static var.
134 (init_foreground_group, tcsetpgrp_without_stopping)
135 (narrow_foreground_group, widen_foreground_group): New functions.
136 (init_sys_modes): Narrow foreground group.
137 (reset_sys_modes): Widen foreground group.
139 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
141 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
143 2012-10-31 Martin Rudalics <rudalics@gmx.at>
145 * minibuf.c (read_minibuf): Restore current buffer since
146 choose_minibuf_frame calling Fset_frame_selected_window may
147 change it (Bug#12766).
149 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
151 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
153 2012-10-30 Kenichi Handa <handa@gnu.org>
155 * font.c (Ffont_at): If WINDOW is specified and it is not
156 displaying the current buffer, signal an error.
158 2012-10-29 Daniel Colascione <dancol@dancol.org>
160 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
161 In preparation for fixing bug#12739, move these functions from
164 * coding.h, coding.c: ... to here, and compile them only when
165 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
166 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
168 2012-10-28 Eli Zaretskii <eliz@gnu.org>
170 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
171 (timer_loop, getitimer, setitimer): Use it instead of
172 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
174 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
177 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
179 * nsterm.m (NO_APPDEFINED_DATA): New define.
180 (last_appdefined_event_data): New variable
181 (last_appdefined_event): Remove.
182 (ns_select): Initialize t from last_appdefined_event_data instead
183 of [last_appdefined_event data1].
184 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
185 remove last_appdefined_event (Bug#12698).
187 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
189 * frame.c (x_set_font): Catch internal error.
191 2012-10-27 Eli Zaretskii <eliz@gnu.org>
193 Avoid overflow in w32 implementation of interval timers.
194 When possible, for ITIMER_PROF count only times the main thread
196 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
197 'volatile ULONGLONG' types. All the other data which was
198 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
199 (GetThreadTimes_Proc): New typedef.
200 (w32_get_timer_time): New function, returns a suitable time value
202 (timer_loop): Enter critical section when accessing ULONGLONG
203 values of the itimer_data struct, as these accesses are no longer
204 atomic. Call 'w32_get_timer_time' instead of 'clock'.
205 Remove unused variable.
206 (init_timers): Initialize s_pfn_Get_Thread_Times.
207 (start_timer_thread): Don't assign itimer->caller_thread here.
208 (getitimer): Assign itimer->caller_thread here.
209 (setitimer): Always call getitimer to get the value of ticks_now.

212 2012-10-26 Eli Zaretskii <eliz@gnu.org>
214 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
215 mouse movement events if the menu bar is active. This avoids
216 producing a busy "hour-glass" cursor by Windows if the mouse
217 pointer is positioned over a tooltip shown for some menu item.
219 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
221 Don't assume process IDs fit in int.
222 * emacs.c (shut_down_emacs) [!DOS_NT]:
223 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
224 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
225 Use pid_t, not int, to store process IDs, as 'int'
226 is not wide enough on a few platforms (e.g., AIX and IRIX).
228 2012-10-23 Kenichi Handa <handa@gnu.org>
230 The following change is to make face-font-rescale-alist work
231 correctly for non-ASCII fonts.
233 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
234 (font_open_for_lface): Handle Vface_font_rescale_alist.
236 2012-10-23 Chong Yidong <cyd@gnu.org>
238 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
240 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>

246 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
249 2012-10-21 Glenn Morris <rgm@gnu.org>
251 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
253 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
256 * frame.c (Fmouse_position, Fmouse_pixel_position):
257 * xdisp.c (produce_stretch_glyph):
258 Declare local vars only when they're needed.
259 This is clearer and avoids a warning on OpenBSD about unused vars.
260 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
261 This is safer, and avoids OpenBSD warnings about unused vars.
262 * keyboard.c (record_menu_key): Remove unnecessary decl.
263 (poll_timer): Define only if POLL_FOR_INPUT is defined.
264 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
265 as our definition clashes with OpenBSD's.
266 * xfaces.c (load_face_colors, check_lface_attrs)
267 (get_lface_attributes_no_remap, get_lface_attributes)
268 (lface_fully_specified_p, x_supports_face_attributes_p)
269 (tty_supports_face_attributes_p, face_fontset, realize_face)
270 (realize_x_face, realize_tty_face):
271 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
272 merely Lisp_Object *. This is more informative and avoids
273 a warning on OpenBSD about accessing beyond an object's size.
275 2012-10-20 Chong Yidong <cyd@gnu.org>
277 * lread.c (Fload): Doc fix (Bug#12592).

281 * font.c (Ffont_at): Fix previous change.
283 2012-10-19 Eli Zaretskii <eliz@gnu.org>
285 * puresize.h (BASE_PURESIZE): Bump the base value to 1700000.
286 See http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00593.html
289 * alloc.c (NSTATICS): Decrease to 0x800.
291 2012-10-19 Stefan Monnier <monnier@iro.umontreal.ca>

298 * nsterm.m (ns_select): Check writefds before call to
299 FD_ISSET (Bug#12668).
301 2012-10-18 Daniel Colascione <dancol@dancol.org>
303 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
304 (staticpro): If we run out of staticpro slots, die with an
305 informative error instead of just calling emacs_abort.

352 Lisp_Object values. (Bug#12661)
354 * w32fns.c (w32_msg_pump): Use XIL instead of casting an integer
355 to Lisp_Object. (Bug#12661)
357 2012-10-17 Kenichi Handa <handa@gnu.org>

463 * fileio.c (check_existing): New function.
464 (make_temp_name, Ffile_exists_p, Ffile_writable_p): Call it

556 * nsmenu.m (ns_update_menubar):
557 * process.c (wait_reading_process_output):
558 * search.c (scan_buffer, scan_newline):
559 Use bool for boolean.
560 * keyboard.c (timers_run, swallow_events)
561 (detect_input_pending_run_timers):
562 * process.c (wait_reading_process_output):
563 Use unsigned for counter where wraparound-on-overflow is desired,
564 since unsigned is guaranteed to have that behavior and signed is not.
565 (read_char): Use ptrdiff_t for string length.
566 (get_input_pending): Remove first argument, since it was always
567 the same pointer-to-int (now pointer-to-boolean) &input_pending,
568 and behave as if it had that value. Return new value of
569 input_pending. All callers changed.
570 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
571 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's
573 * keymap.c (push_key_description): Omit last arg, which was always 1.
576 * regex.c (immediate_quit) [emacs]: Remove duplicate decl.
578 2012-10-10 Juanma Barranquero <lekktu@gmail.com>
580 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/indent.$(O))
581 ($(BLD)/term.$(O)): Update dependencies.
583 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>
585 * alloc.c (mark_object): Use meaningful PVEC_NORMAL_VECTOR.
586 * lisp.h (enum pvec_type): Adjust comments and omit explicit
587 initializer for PVEC_NORMAL_VECTOR.
589 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
591 Clean out old termopts cruft.
592 * termopts.h (flow_control, meta_key): Remove unused decls.
593 * dispnew.c, indent.c, nsterm.m, term.c, xsettings.c, xsmfns.c:
594 Don't include termopts.h.
596 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>
598 * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers.
600 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
602 * commands.h (immediate_quit): Remove duplicate decl.
604 2012-10-09 Jan Djärv <jan.h.d@swipnet.se>
606 * nsfont.m (Vfonts_in_cache): Remove, not needed as font.c handles
608 (nsfont_open): Remove setting of Vfonts_in_cache.
609 (syms_of_nsfont): Remove initialization of Vfonts_in_cache.
611 2012-10-09 Eli Zaretskii <eliz@gnu.org>
613 * w32fns.c (w32_last_error): Change the return value to DWORD, to
614 match what GetLastError returns. Explain why the function is
617 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
618 'is_tooltip_frame', to avoid confusion with its global namesake.
620 2012-10-08 Daniel Colascione <dancol@dancol.org>
622 * xdisp.c (start_hourglass): Call w32_note_current_window when
623 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
624 build that caused Emacs to display the hourglass cursor forever.
626 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
627 which is broken under remote desktop, calculate the number of
628 colors available for a display based on the display's number of
629 planes and number of bits per pixel per plane. (bug#10397).
631 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
633 * nsfont.m (Vfonts_in_cache): New variable.
634 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
635 are used. Add cached fonts to Vfonts_in_cache.
636 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
638 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
640 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
642 (FONT_H): Define after FRAME_H.
643 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
646 * w32term.c: Remove leftover declaration of keyboard_codepage.
648 2012-10-08 Eli Zaretskii <eliz@gnu.org>
650 * makefile.w32-in (FONT_H): Add $(FRAME_H).
651 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
652 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
653 (GLOBAL_SOURCES): Add cygw32.c.
654 ($(BLD)/unexw32.$(O)):
656 ($(BLD)/w32console.$(O)):
657 ($(BLD)/w32fns.$(O)):
658 ($(BLD)/w32heap.$(O)):
659 ($(BLD)/w32menu.$(O)):
660 ($(BLD)/w32proc.$(O)): Add w32common.h.
662 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
664 (x_to_w32_color): Don't modify the argument, modify a copy instead.
666 2012-10-08 Daniel Colascione <dancol@dancol.org>
668 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
669 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
670 accidental message numbering hole. Change other messages to
673 * w32select.h (HAVE_W32SELECT): Remove.
675 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
676 w32common.h instead of w32heap.h.
678 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
679 (get_allocation_unit, get_processor_type, get_w32_major_version)

686 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
687 (w32_minor_version, w32_build_number, w32_subtype):
688 Remove duplicate definitions.
690 * w32fns.c: Include w32common.h; include w32heap.h only in
693 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
694 Use `report_file_error' instead of `error' in order to better
695 inform users of what went wrong. Increase NTGUI_UNICODE file
696 dialog box file name length to 32k, the maximum allowed by the NT
699 * w32common.h: New file.
700 (ROUND_UP, ROUND_DOWN, get_page_size)
701 (get_allocation_unit, get_processor_type, get_w32_major_version)
702 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
703 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
704 (OS_NT, os_subtype, cache_system_info): Move here.
706 * unexw32.c, unexcw.c: Include w32common.h.
708 * emacs.c (main): Use (defined (WINDOWSNT) || defined
709 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
710 to call syms_of_w32select.
712 * cygw32.h: Remove obsolete EXFUN declarations.
714 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
716 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
717 of w32inevt.o from SOME_MACHINE_OBJECTS.
719 2012-10-08 Daniel Colascione <dancol@dancol.org>
721 * image.c: Permanent fix for JPEG compilation issue --- limit
722 jpeglib `boolean' redefinition to Cygwin builds.
724 2012-10-08 Eli Zaretskii <eliz@gnu.org>
726 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
728 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
731 2012-10-08 Daniel Colascione <dancol@dancol.org>
733 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
734 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
735 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
736 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
737 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
738 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
739 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
740 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
741 now a supported configuration.
743 * Makefile.in: consolidate image variables into LIBIMAGE; add
744 W32_OBJ and W32_LIBS. Compile new files.
747 (_DebPrint) declare tracing facility for W32 debugging. We need
748 to unify tracing later.
750 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
751 unconditional use of W32 Unicode functions. Cygwin runs only on
752 100% Unicode operating systems.
754 * cygw32.c: New file. Define Cygwin-specific facilities.
755 (Fcygwin_convert_path_to_windows)
756 (Fcygwin_convert_path_from_windows): New user functions for
757 accessing Cygwin path-munging routines.
759 * cygw32.h: New file.
760 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
761 UTF-16LE strings temporarily inside non-Lisp-visible string
764 (w32_strerror): Just what it says on the tin.
766 * emacs.c: Make the NS fork-then-exec code for daemon-launching
767 also run for Cygwin; both systems have the same problem with using
768 GUI facilities in a forked child. Also call syms_of_cygw32,
769 syms_of_w32select in correct places.
771 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
772 needs fork-then-exec for daemon launching.
774 * font.h: Include frame.h.
776 * image.c: Use the image library cache machinery only when we're
777 compiling for native WINDOWSNT; Cygwin can use shared libraries
778 like any other Unixlike system.
780 * keyboard.c: Clarify a comment regarding the input loop.
782 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
783 functions directly instead of trying to detect at runtime that our
784 host operating system supports them. We make this change for two
785 reasons: Cygwin lacks support for the multibyte character
786 conversion functions used by the legacy menu code, and Cygwin
787 never needs to rely on non-Unicode APIs.
789 * unexw32.c (hinst): Declare extern.
791 * w32.c: Change header order;
792 (w32_strerror): Move to w32fns.c because we need it for
793 non-WINDOWSNT builds.
795 * w32.h: Add #error macro to make sure we don't include w32.h for
796 Cygwin builds. Remove w32select declarations.
798 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
799 w32fns.c. w32console.c is WINDOWSNT-only.
801 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
802 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
804 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
805 (w32_major_version, w32_minor_version, w32_build_number)
806 (os_subtype, sound_type): Define here
807 (w32_defined_color): Make color parameter const for consistency
808 with other _defined_color functions.
809 (w32_createwindow): Unconditionally call w32_init_class instead of
810 doing so only when hprevinst is non-NULL. Plumbing hprevinst
811 through the code is complex and unnecessary because class
812 registration is practically free.
813 (w32_name_of_message): New EMACSDEBUG-only function.
814 (Fset_message_beep): Move here
815 (Fx_open_connection): Require that the display name for Windows be
816 "w32" for consistency, emacsclient disambiguation, and maybe, one
817 day, multi-window-system support.
818 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
819 Cygwin files for W32 GUI facilities, since these clearly don't
822 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
823 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
824 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
825 (w32_last_error): Remove.
827 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
829 * w32heap.c (syspage_mask): Declare here.
830 (cache_system_info): Remove.
832 * w32inevt.c (faked_key): Define globally, not statically.
833 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
834 (w32_console_toggle_lock_key): Move to w32fns.c.
836 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
838 * w32proc.c (_DebPrint): Move to w32fns.c.
839 * w32select.c: Include string.h, stdio.h for Cygwin.
840 * w32select.h: New File.
842 * w32term.c: Include io.h for non-CYGWIN builds; needed for
844 (w32_message_fd): New variable. Under Cygwin, holds the file
845 descriptor the system used to tell us about pending thread
848 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
849 that prevented compilation under non-WINDOWSNT systems.
851 (w32_initialize): Open /dev/windows and assign it to
852 w32_message_fd. Provide w32 feature.
854 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
855 (WM_EMACS_INPUT_READY): add.
856 (prepend_msg, w32_message_fd): Declare globally.
859 (keyboard_handle): Use only when WINDOWSNT.
860 (notify_msg_ready): New function. Posts a message to the main
861 thread's message queue under CYGWIN, which wakes up the main
862 thread from select(2) by making the /dev/windows file descriptor
863 ready. Under WINDOWSNT, it sets an event the same way the old
866 (post, prepend_msg): Actually call notify_msg_ready instead of
867 setting the input event directly.
869 2012-10-07 Eli Zaretskii <eliz@gnu.org>
871 * ralloc.c (relinquish): If a heap is ready to be relinquished,
872 but it still has blocs in it, don't return it to the system,
873 instead of aborting. (Bug#12402)
875 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
877 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
879 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
880 MAC_OS_X_VERSION_10_6.
881 (syms_of_nsterm): Remove comment about Panther and above for
883 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.

888 MAC_OS_X_VERSION_10_4.
890 * nsmenu.m (fillWithWidgetValue:): Remove code for <
891 MAC_OS_X_VERSION_10_2.
893 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
895 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
896 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
898 * nsterm.m (ns_in_resize): Remove (Bug#12479).
899 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
900 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
901 Remove ns_in_resize check.
902 (ns_clear_frame_area): Remove resize handle code.
904 * nsfns.m (ns_in_resize): Remove.
905 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
906 Remove ns_in_resize check.
908 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
910 Improve sys_siglist detection.
911 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
912 defined as a macro, as is done in Solaris.
913 (sys_siglist_entries): New macro.
914 (save_strsignal): Use it.
915 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
916 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
918 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
920 * nsfns.m (Fx_create_frame): Call x_default_parameter with
921 fullscreen/Fullscreen.

926 * nsterm.m (x_make_frame_visible): Check for fullscreen.
927 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
928 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
929 (windowDidResize:): Check for correct window if old style fullscreen.
930 Capitalize word in comment. Remove incorrect comment.
931 (initFrameFromEmacs:): tbar_height renamed tibar_height.
932 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
933 error in drawing background.
934 (toggleFullScreen:): Remove comment. Rearrange calls.
935 Set toolbar values to zero, save old height in tobar_height.
936 Restore tool bar height when leaving fullscreen.
937 (canBecomeMainWindow): New function.
939 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
941 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
943 2012-10-05 Eli Zaretskii <eliz@gnu.org>
945 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
947 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
948 that time stamps of directories could also be changed.
949 Don't request the too broad GENERIC_WRITE, only the more restrictive
950 FILE_WRITE_ATTRIBUTES access rights.
952 * fileio.c (Fset_file_times): Special-case ignoring errors for
953 directories only on MSDOS, not on MS-Windows.
955 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
957 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
959 2012-10-04 Eli Zaretskii <eliz@gnu.org>
961 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
962 see whether CreateFile failed.
964 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
966 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
967 to avoid similar races.
968 * keyboard.c (pending_signals): Now bool, not int.
970 Port timers to OpenBSD, plus check for timer failures.
971 OpenBSD problem reported by Han Boetes.
972 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
974 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
975 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
976 like OpenBSD, which has timer_settime but does not declare it.
977 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
978 whether to use itimerspec-related primitives. All uses of
979 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
981 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
983 * profiler.c (handle_profiler_signal): Fix a malloc race
984 that caused Emacs to hang on Fedora 17 when profiling Lisp.
986 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
988 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
990 2012-10-02 Eli Zaretskii <eliz@gnu.org>
992 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
993 consistent with the change in return value of 'safe_strsignal'.
995 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
997 Prefer plain 'static' to 'static inline' (Bug#12541).
998 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
999 (bidi_set_sor_type, bidi_push_embedding_level)
1000 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
1001 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)
1002 (bidi_cache_search, bidi_cache_ensure_space)

1006 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
1007 Now 'static', not 'static inline'.
1009 Count overruns when profiling; change units to ns.
1010 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
1011 Give extra weight to samples after overruns, to attempt to count
1012 the time more accurately.
1013 (setup_cpu_timer): Change sampling interval units from ms to ns, since
1014 the underlying primitives nominally do ns.
1015 (Fprofiler_cpu_start): Document the change. Mention that
1016 the sampling intervals are only approximate.
1018 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
1020 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.

1032 Update dependencies.
1034 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
1036 Fix a malloc race condition involving strsignal.
1037 A signal can arrive in the middle of a malloc, and Emacs's signal
1038 handler can invoke strsignal, which can invoke malloc, which is
1039 not portable. This race condition bug makes Emacs hang on GNU/Linux.
1040 Fix it by altering the signal handler so that it does not invoke
1042 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
1043 * process.c (status_message): Use const pointer, in case strsignal
1044 is #defined to safe_strsignal.
1045 * sysdep.c (sys_siglist, init_signals): Always define and
1046 initialize a substitute sys_siglist if the system does not define
1047 one, even if HAVE_STRSIGNAL.
1048 (safe_strsignal): Rename from strsignal. Always define,
1049 using sys_siglist. Return a const pointer.
1050 * syssignal.h (safe_strsignal): New decl.
1051 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
1053 2012-10-01 Eli Zaretskii <eliz@gnu.org>
1055 * w32proc.c (timer_loop): Fix code that waits for timer
1056 expiration, to avoid high CPU usage.
1058 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
1060 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
1061 (sweep_weak_table): Remove redundant prototypes.
1063 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
1065 * emacs.c: Move the inclusion of TERM_HEADER after including
1066 windows.h on WINDOWSNT. This avoids compilation problems with
1069 2012-10-01 Eli Zaretskii <eliz@gnu.org>
1071 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
1072 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
1073 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
1074 as the previous version used 'void *'.
1076 * ralloc.c (ROUNDUP): Fix last change.
1077 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
1080 * w32proc.c <disable_itimers>: New static flag.
1081 (init_timers): Initialize it to zero, after creating the critical
1082 sections used by the timer threads.
1083 (term_timers): Set to 1 before deleting the critical sections.
1084 (getitimer, setitimer): If disable_itimers is non-zero, return an
1085 error indication without doing anything. Reported by Fabrice
1086 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
1087 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
1089 [!HAVE_SETITIMER]: Behave as the previous version that didn't
1092 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
1093 term_ntproc after all the other bookkeeping, to get timers working
1094 as long as possible.
1096 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
1098 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
1099 Suggested by Juri Linkov in
1100 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
1102 Prefer plain 'static' to 'static inline' (Bug#12541).
1103 With static functions, modern compilers inline pretty well by
1104 themselves; advice from programmers often hurts as much as it helps.
1105 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
1106 this change shrinks the text size of the Emacs executable by 1.1%
1107 without affecting CPU significantly in my benchmark.

1188 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
1190 Revert the FOLLOW-SYMLINKS change for file-attributes.
1191 Doing it right would require several changes to Tramp, and there's
1192 not enough time to get that tested before the freeze today.
1193 * dired.c (directory_files_internal, Ffile_attributes):
1196 * frame.c (x_report_frame_params): Port better to wider ints.

1230 * w32.c (init_environment, get_emacs_configuration): Support AMD64
1232 (init_ntproc): Cast arguments of _open_osfhandle to intptr_t, for
1233 compatibility with x64.
1235 * vm-limit.c (lim_data): Now size_t.
1236 (check_memory_limits): Adjust prototypes of real_morecore and
1237 __morecore to receive argument of type ptrdiff_t. Use size_t for
1238 five_percent and data_size.
1240 * unexw32.c: Use DWORD_PTR instead of DWORD for file-scope
1241 variables, for compatibility with x64.

1264 value of FRAME_X_WINDOW, to fit a 64-bit pointer on 64-bit Windows

1293 (struct itimer_data): New definition.
1294 (ticks_now, real_itimer, prof_itimer, clocks_min, crit_real)

1386 HAVE_TIMER_SETTIME is defined.
1388 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
1390 Profiler improvements: more-accurate timers, overflow checks.
1391 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
1392 signal.h, setjmp.h. Include systime.h instead.
1393 (saturated_add): New function.
1394 (record_backtrace, current_sample_interval): Use EMACS_INT, not size_t.

1400 All uses changed to store the new value.
1401 (handle_profiler_signal): Rename from sigprof_handler_1,
1402 for consistency with other handlers. Do not check whether
1403 cpu_log is a hash-table if garbage collecting, since it
1404 doesn't matter in that case.
1405 (deliver_profiler_signal): Rename from sigprof_handler,
1406 for consistency with other handlers.
1407 (setup_cpu_timer): New function, with much of what used to be in
1408 Fprofiler_cpu_start. Check for out-of-range argument.
1409 Prefer timer_settime if available, and prefer
1410 thread cputime clocks, then process cputime clocks, then
1411 monotonic clocks, to the old realtime clock. Use make_timeval
1412 to round more-correctly when falling back to setitimer.
1413 (Fprofiler_cpu_start): Use it.
1414 (Fprofiler_cpu_stop): Prefer timer_settime if available.
1415 Don't assume that passing NULL as the 2nd argument of setitimer
1416 is the same as passing a pointer to all-zero storage.
1417 Ignore SIGPROF afterwards.
1418 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
1419 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
1420 non-fatal signal handlers. Ignore SIGPROF on startup.
1421 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
1422 in profiler.c, since sysdep.c now uses it.
1424 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.

1462 * Makefile.in (LIB_TIMER_TIME): New macro.
1464 * atimer.c (alarm_timer, alarm_timer_ok, set_alarm, init_atimer):
1465 Use HAVE_TIMER_SETTIME, not SIGEV_SIGNAL, to decide whether to
1468 2012-09-26 Tomohiro Matsuyama <tomo@cx4a.org>

1476 2012-09-26 Paul Eggert <eggert@cs.ucla.edu>
1478 * character.h (MAYBE_UNIFY_CHAR): Remove.
1479 * charset.c, charset.h (maybe_unify_char): Now static.
1480 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
1481 Since this stuff is now private to charset.c, there's no need for
1482 a public macro and no need to inline by hand.

1511 2012-09-25 Juanma Barranquero <lekktu@gmail.com>
1513 * makefile.w32-in ($(BLD)/callproc.$(O)): Update dependencies.
1515 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>
1517 Prefer POSIX timers if available.
1518 They avoid a race if the timer is too close to the current time.
1519 * atimer.c (alarm_timer, alarm_timer_ok) [SIGEV_SIGNAL]: New static vars.
1520 (set_alarm) [SIGEV_SIGNAL]: Use POSIX timers if available.
1521 (init_atimer) [SIGEV_SIGNAL]: Initialize them.
1523 2012-09-25 Eli Zaretskii <eliz@gnu.org>

1532 Move Vlibrary_cache to emacs.c and reset before dumping.
1534 * lisp.h (reset_image_types): Declare.

1537 * image.c (reset_image_types): New function.
1539 * emacs.c [WINDOWSNT] (Vlibrary_cache): Move from w32.c.

1546 * w32.h (Vlibrary_cache): Do not declare.
1548 2012-09-25 Eli Zaretskii <eliz@gnu.org>
1550 * w32proc.c (sys_signal): Handle all signals defined by the
1551 MS-Windows runtime, not just SIGCHLD. Actually install the signal
1552 handlers for signals supported by Windows. Don't override
1553 term_ntproc as the handler for SIGABRT.
1554 (sigaction): Rewrite to call sys_signal instead of duplicating its
1556 (sys_kill): Improve commentary.
1558 * w32.c (term_ntproc): Accept (and ignore) one argument, for
1559 consistency with a signature of a signal handler. All callers
1561 (init_ntproc): Accept an argument DUMPING. If dumping, don't
1562 install term_ntproc as a signal handler for SIGABRT, as that
1563 should be done by the dumped Emacs.
1565 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
1567 * w32select.c (term_w32select): Protect against repeated
1568 invocation by setting clipboard_owner to NULL after calling

1579 2012-09-25 Chong Yidong <cyd@gnu.org>
1581 * xdisp.c (mode_line_inverse_video): Delete obsolete variable.
1583 2012-09-24 Stefan Monnier <monnier@iro.umontreal.ca>
1585 * bytecode.c (exec_byte_code): Signal an error instead of aborting,
1586 when encountering an unknown bytecode.
1588 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
1590 image.c, indent.c: Use bool for booleans.
1591 * dispextern.h (struct image_type): Members valid_p, load, init
1592 now return bool, not int. All uses changed.
1593 * image.c: Omit unnecessary static decls.
1594 (x_create_bitmap_mask, x_build_heuristic_mask):
1595 Return void, not int, since callers don't care about the return value.

1628 * chartab.c (Fset_char_table_default): Obsolete function removed.
1630 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
1632 Move pid_t related decls out of lisp.h.
1633 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
1634 (interruptible_wait_for_termination):
1635 Move these decls from lisp.h to syswait.h, since they use pid_t.
1636 Needed on FreeBSD; see Herbert J. Skuhra in
1637 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
1638 * callproc.c: Include syswait.h.

1656 * nsmenu.m, w32menu.c, xmenu.c (set_frame_menubar):
1657 * xfns.c (Fx_show_tip) [USE_GTK]:
1658 Use bool for boolean.
1659 * gtkutil.c (xg_update_frame_menubar):
1660 * xmenu.c (update_frame_menubar):
1661 Return void, not int, since caller ignores return value.
1662 * gtkutil.c (xg_change_toolbar_position):
1665 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
1667 * makefile.w32-in (BLOCKINPUT_H): Remove.

1684 2012-09-23 Eli Zaretskii <eliz@gnu.org>
1686 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
1687 fatal_error_backtrace.
1689 * w32proc.c (sys_kill): Undo last change: don't do anything when
1690 invoked to deliver SIGABRT to our own process. This is now
1691 handled by emacs_raise.
1693 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
1695 * w32term.c (w32_read_socket): Remove leftover reference to
1696 interrupt_input_pending.
1698 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
1700 Do not use SA_NODEFER.
1701 Problem reported by Dani Moncayo in
1702 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
1704 * sysdep.c (emacs_abort): Do not reset signal handler.
1705 * emacs.c (terminate_due_to_signal): Reset signal handler here.
1706 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
1707 wanted even on POSIXish hosts, and it doesn't work on Windows.
1709 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
1711 * xterm.c (x_term_init): Call fixup_locale before and after calling
1712 gtk_init (Bug#12392).
1714 2012-09-23 Chong Yidong <cyd@gnu.org>
1716 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
1717 Vdynamic_library_alist.
1719 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
1720 (Fgnutls_available_p): Caller changed.
1722 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
1723 (Flibxml_parse_xml_region): Likewise.
1725 * dispextern.h (struct image_type): Remove arg from init function.
1727 * image.c (Finit_image_library, lookup_image_type)
1728 (define_image_type): Remove now-unneeded second arg.
1729 (init_xpm_functions, init_png_functions, init_jpeg_functions)
1730 (init_tiff_functions, init_gif_functions, init_svg_functions):
1731 Arglist and w32_delayed_load calling convention changed.
1732 (gs_type): Remove init_gs_functions; there is no such function.
1733 (valid_image_p, make_image): Fix caller to lookup_image_type.
1735 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
1737 Simplify and avoid signal-handling races (Bug#12471).
1739 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
1740 Avoid recursive loop if there's a fatal error in the function itself.
1741 * atimer.c (pending_atimers):
1742 * blockinput.h: Don't include "atimer.h"; no longer needed.
1743 (interrupt_input_pending): Remove. All uses removed.
1744 pending_signals now counts both atimers and ordinary interrupts.
1745 This is less racy than having three separate pending-signal flags.
1746 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
1748 Rename from their upper-case counterparts BLOCK_INPUT,
1749 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
1750 INPUT_BLOCKED_P, and turn into functions. All uses changed.
1751 This makes it easier to access volatile variables more accurately.
1752 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
1753 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
1754 that's more reliable if the code is buggy and sets
1755 interrupt_input_blocked to a negative value. All uses changed.
1756 * atimer.c (deliver_alarm_signal):
1757 Remove. No need to deliver this to the parent; any thread can
1758 handle this signal now. All uses replaced by underlying handler.
1759 * atimer.c (turn_on_atimers):
1760 * dispnew.c (handle_window_change_signal):
1761 * emacs.c (handle_danger_signal):
1762 * keyboard.c (kbd_buffer_get_event):
1763 Don't reestablish signal handler; not needed with sigaction.
1764 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
1766 Rework to avoid unnecessary accesses to volatile variables.
1767 (UNBLOCK_INPUT_TO): Now a function.
1768 (totally_unblock_input, unblock_input): New decls.
1769 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
1770 (init_data): Remove. Necessary stuff now done in init_signal.
1771 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
1772 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
1773 (fatal_error_code): Remove; no longer needed.
1774 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
1775 it doesn't always backtrace. All uses changed. No need to reset
1776 signal to default, since sigaction and/or die does that for us now.
1777 Use emacs_raise (FOO), not kill (getpid (), FOO).
1778 (main): Check more-accurately whether we're dumping.
1779 Move fatal-error setup to sysdep.c
1780 * floatfns.c: Do not include "syssignal.h"; no longer needed.
1781 * gtkutil.c (xg_get_file_name, xg_get_font):
1782 Remove no-longer-needed signal-mask manipulation.
1783 * keyboard.c, process.c (POLL_FOR_INPUT):
1784 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
1785 * keyboard.c (read_avail_input): Remove.
1786 All uses replaced by gobble_input.
1787 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
1788 (kbd_buffer_store_event_hold, gobble_input):
1789 (record_asynch_buffer_change) [USABLE_SIGIO]:
1790 (store_user_signal_events):
1791 No need to mess with signal mask.
1792 (gobble_input): If blocking input and there are terminals, simply
1793 set pending_signals to 1 and return. All hooks changed to not
1794 worry about whether input is blocked.
1795 (process_pending_signals): Clear pending_signals before processing
1796 them, in case a signal comes in while we're processing.
1797 By convention callers now test pending_signals before calling us.
1798 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
1799 New functions, to support changes to blockinput.h.
1800 (handle_input_available_signal): Now extern.
1801 (reinvoke_input_signal): Remove. All uses replaced by
1803 (quit_count): Now volatile, since a signal handler uses it.
1804 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
1805 All callers changed. Block SIGINT only if not already blocked.
1806 Clear sigmask reliably, even if Fsignal returns, which it can.
1807 Omit unnecessary accesses to volatile var.
1808 (quit_throw_to_read_char): No need to restore sigmask.
1809 * keyboard.c (gobble_input, handle_user_signal):
1810 * process.c (wait_reading_process_output):
1811 Call signal-handling code rather than killing ourselves.
1812 * lisp.h: Include <float.h>, for...
1813 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
1814 (pending_signals): Now volatile.
1815 (syms_of_data): Now const if IEEE floating point.
1816 (handle_input_available_signal) [USABLE_SIGIO]:
1817 (terminate_due_to_signal, record_child_status_change): New decls.
1818 * process.c (create_process): Avoid disaster if memory is exhausted
1819 while we're processing a vfork, by tightening the critical section
1821 (send_process_frame, process_sent_to, handle_pipe_signal)
1822 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
1824 (send_process): No need for setjmp/longjmp any more, since the
1825 SIGPIPE stuff is now gone. Instead, report an error if errno
1827 (record_child_status_change): Now extern. PID and W are now args.
1828 Return void, not bool. All callers changed.
1829 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
1830 Remove. All uses removed. This bug should be fixed now in a
1832 (wait_for_termination_1): Use waitpid rather than sigsuspend,
1833 and record the child status change directly. This avoids the
1834 need to futz with the signal mask.
1835 (process_fatal_action): Move here from emacs.c.
1836 (emacs_sigaction_flags): New function, containing
1837 much of what used to be in emacs_sigaction_init.
1838 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
1839 caught by emacs, to make races less likely.
1840 (deliver_process_signal): Rename from handle_on_main_thread.
1842 (BACKTRACE_LIMIT_MAX): Now at top level.
1843 (thread_backtrace_buffer, threadback_backtrace_pointers):
1845 (deliver_thread_signal, deliver_fatal_thread_signal):
1846 New functions, for more-accurate delivery of thread-specific signals.
1847 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
1848 (deliver_arith_signal): Handle in this thread, not
1849 in the main thread, since it's triggered by this thread.
1850 (maybe_fatal_sig): New function.
1851 (init_signals): New arg DUMPING so that we can be more accurate
1852 about whether we're dumping. Caller changed.
1853 Treat thread-specific signals differently from process-general signals.
1854 Block all signals while handling fatal error; that's safer.
1855 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
1857 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
1858 Ignore SIGPIPE unless batch.
1859 (emacs_backtrace): Output backtrace for the appropriate thread,
1860 which is not necessarily the main thread.
1861 * syssignal.h: Include <stdbool.h>.
1862 (emacs_raise): New macro.
1863 * xterm.c (x_connection_signal): Remove; no longer needed
1864 now that we use sigaction.
1865 (x_connection_closed): No need to mess with sigmask now.
1866 (x_initialize): No need to reset SIGPIPE handler here, since
1867 init_signals does this for us now.

1871 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
1872 background rect may be larger (Bug#12245).
1874 2012-09-23 Chong Yidong <cyd@gnu.org>
1876 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
1878 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
1880 * .gdbinit: Just stop at fatal_error_backtrace.
1881 See Stefan Monnier's request in
1882 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
1883 Remove no-longer-used query of system type.
1885 2012-09-22 Chong Yidong <cyd@gnu.org>
1887 * search.c (Freplace_match): Doc fix (Bug#12325).
1889 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
1891 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
1892 (Fline_end_position): Doc fix.
1894 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
1896 2012-09-22 Chong Yidong <cyd@gnu.org>
1898 * dispextern.h (struct image_type): Add new slot, storing a type
1899 initialization function.
1901 * image.c (define_image_type): Call the image initializer function
1902 if it is defined. Arguments and return value changed.
1903 (valid_image_p, make_image): Callers changed.
1904 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
1905 (gif_type, imagemagick_type, svg_type, gs_type):
1906 Add initialization functions.
1907 (Finit_image_library): Call lookup_image_type.
1908 (CHECK_LIB_AVAILABLE): Macro deleted.
1909 (lookup_image_type): Call define_image_type here, rather than via
1910 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
1911 (syms_of_image): Move define_image_type calls for xbm_type and
1912 pbm_type to lookup_image_type.
1914 2012-09-22 Eli Zaretskii <eliz@gnu.org>
1916 * keyboard.c (timer_check_2): Move calculation of 'timers' and
1917 'idle_timers' from here ...
1918 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
1919 lists, to avoid infloops when the timer does something stupid,
1920 like reinvoke itself with the same or smaller time-out.
1923 2012-09-22 Martin Rudalics <rudalics@gmx.at>
1925 * window.c (Fsplit_window_internal): Handle only Qt value of
1926 Vwindow_combination_limit separately.
1927 (Qtemp_buffer_resize): New symbol.
1928 (Vwindow_combination_limit): New default value.
1931 2012-09-22 Eli Zaretskii <eliz@gnu.org>
1933 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
1934 the new overlay string. (Bug#10159)
1936 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
1938 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
1939 or that fprintf is async-signal-safe. POSIX doesn't require
1942 2012-09-22 Chong Yidong <cyd@gnu.org>
1944 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
1947 2012-09-22 Kenichi Handa <handa@gnu.org>
1949 * composite.c (composition_reseat_it): Handle the case that a
1950 grapheme cluster is not covered by a single font (Bug#12352).
1952 2012-09-21 Chong Yidong <cyd@gnu.org>
1954 * image.c (define_image_type): Avoid adding duplicate types to
1955 image_types (Bug#12463). Suggested by Jörg Walter.
1957 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1959 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
1960 (print_load_command_name): Add case LC_DATA_IN_CODE.
1961 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
1963 2012-09-21 Glenn Morris <rgm@gnu.org>
1965 * eval.c (Frun_hook_with_args_until_success)
1966 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
1968 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
1970 * fileio.c (Ffile_selinux_context): Only call freecon when
1971 lgetfilecon succeeded.
1972 (Fset_file_selinux_context): Likewise. (Bug#12444)
1974 2012-09-21 Eli Zaretskii <eliz@gnu.org>
1976 * xdisp.c (try_window_reusing_current_matrix): Under bidi
1977 reordering, locate the cursor by calling set_cursor_from_row; if
1978 that fails, clear the desired glyph matrix before returning a
1979 failure indication to the caller. Fixes leaving garbled display
1980 when fast scrolling with a down-key. (Bug#12403)
1981 (compute_stop_pos_backwards): Fix a typo that caused crashes while
1982 scrolling through multibyte text.
1984 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
1986 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
1987 calling mark_vectorlike since that's the one that marks the window.
1988 (mark_discard_killed_buffers): Mark the final cdr.
1989 * window.h (struct window): Move prev/next_buffers to the
1990 non-standard fields.
1991 * window.c (make_window): Initialize prev/next_buffers manually.
1993 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
1995 Omit unused arg EXPECTED from socket hooks.
1996 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
1997 * nsterm.m (ns_term_init):
1998 * termhooks.h (struct terminal.read_socket_hook):
1999 * w32inevt.c (w32_console_read_socket):
2000 * w32term.c (w32_read_socket):
2001 * xterm.c (XTread_socket):
2002 Omit unused arg EXPECTED. All callers changed.
2003 (store_user_signal_events): Return void, not int, since callers no
2004 longer care about the return value. All uses changed.
2006 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
2008 * w32gui.h (XParseGeometry): Do not declare.
2010 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
2012 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
2013 Ignore 'expected'. See Eli Zaretskii in
2014 <http://bugs.gnu.org/12471#8> (last line).
2016 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
2017 (XParseGeometry): Now static. Substitute extremal values for
2018 values that are out of range.
2020 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
2022 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
2024 * nsfns.m (XParseGeometry): Remove.
2025 (Fx_create_frame): Call x_set_offset to correctly interpret
2026 top_pos in geometry.
2028 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
2029 (Fx_parse_geometry): If there is a space in string, call
2030 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
2032 2012-09-17 Eli Zaretskii <eliz@gnu.org>
2034 * search.c (scan_buffer): Use character positions in calls to
2035 region_cache_forward and region_cache_backward, not byte
2036 positions. (Bug#12196)
2038 * w32term.c (w32_read_socket): Set pending_signals to 1, like
2039 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
2041 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
2042 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
2043 emacs_blocked_malloc, now deleted.
2045 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
2047 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
2048 The workaround was for improving performance on Solaris 2.4, but
2049 is getting in the way now. Emacs will still work if someone is
2050 still running Solaris 2.4 in a museum somewhere; Sun dropped
2051 support for Solaris 2.4 in 2003.
2052 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
2053 * process.c (create_process) [HAVE_WORKING_VFORK]:
2054 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
2055 since Emacs no longer uses vfork on that platform.
2057 2012-09-17 Glenn Morris <rgm@gnu.org>
2059 * emacs.c: Use COPYRIGHT.
2061 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
2063 Remove configure's --without-sync-input option (Bug#12450).
2064 When auditing signal-handling in preparation for cleaning it up,
2065 I found that SYNC_INPUT has race conditions and would be a real
2066 pain to fix. Since it's an undocumented and deprecated
2067 configure-time option, now seems like a good time to remove it.
2068 Also see <http://bugs.gnu.org/11080#16>.
2069 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
2070 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
2071 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
2072 (malloc_hysteresis):
2073 (check_depth) [XMALLOC_OVERRUN_CHECK]:
2074 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
2075 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
2076 (dont_register_blocks, bytes_used_when_reconsidered)
2077 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
2078 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
2079 [!SYSTEM_MALLOC && !SYNC_INPUT]:
2080 Remove. All uses removed.
2081 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
2082 implementation, one that depends on whether the new macro
2083 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
2085 * atimer.c (run_timers, handle_alarm_signal):
2086 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
2087 (handle_async_input, process_pending_signals)
2088 (handle_input_available_signal, init_keyboard):
2089 * nsterm.m (ns_read_socket):
2090 * process.c (wait_reading_process_output):
2091 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
2092 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
2094 * xterm.c (XTread_socket):
2096 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
2097 * eval.c (handling_signal): Remove. All uses removed.
2098 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
2099 All uses replaced with the SYNC_INPUT version.
2100 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
2102 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
2105 * font.c (Ffont_shape_gstring): Remove unused local.
2107 2012-09-16 Glenn Morris <rgm@gnu.org>
2109 * Makefile.in (clean): No longer run nextstep's clean.
2111 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
2113 (ns-app): Move here from ns.mk, and simplify.
2114 (clean): Simplify nextstep entry.
2115 * ns.mk: Remove file.
2117 2012-09-17 Kenichi Handa <handa@gnu.org>
2119 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
2120 not covert the last few charactes.
2122 2012-09-16 Kenichi Handa <handa@gnu.org>
2124 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
2125 here, but just check the validity of glyphs in the glyph-string.
2127 2012-09-16 Martin Rudalics <rudalics@gmx.at>
2129 * window.c (Fwindow_parameter, Fset_window_parameter):
2130 Accept any window as argument (Bug#12452).
2132 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
2134 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
2135 to ns_term_init to avoid memory leak.
2137 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
2138 explicit retain/release.
2139 (ns_term_init): Only allow one display. Initialize outerpool and
2142 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
2144 Port _setjmp fix to POSIXish hosts as well as Microsoft.
2145 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
2146 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
2147 the Microsoft problem in a different way, by altering ../nt/config.nt.
2149 2012-09-15 Eli Zaretskii <eliz@gnu.org>
2164 * w16select.c: Remove inclusion of setjmp.h, as it is now included
2165 by lisp.h. This completes removal of setjmp.h inclusion
2166 erroneously announced in the previous commit. (Bug#12446)
2168 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
2171 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
2172 not defined as a macro. The latter happens on MS-Windows.
2175 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
2177 Port better to POSIX hosts lacking _setjmp (Bug#12446).
2178 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
2179 Some instances of '#include <setjmp.h>' removed, if the
2180 only reason for the instance was because "lisp.h" was included.
2181 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
2182 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
2183 and _longjmp with the new symbols. Emacs already uses _setjmp if
2184 available, so this change affects only POSIXish hosts that have
2185 sigsetjmp but not _setjmp, such as some versions of Solaris and
2186 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
2187 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
2188 (png_load_body) [HAVE_PNG]:
2189 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
2190 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
2191 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
2192 since PNG requires jmp_buf. This is the only exception to the
2193 general rule that we now use sys_setjmp and sys_longjmp.
2194 This exception is OK since this code does not change the signal
2195 mask or longjmp out of a signal handler.
2197 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
2199 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
2200 Include "syssignal.h", for 'main_thread'.
2202 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
2204 Avoid out-of-range marker position (Bug#12426).
2205 * insdel.c (replace_range, replace_range_2):
2206 Adjust markers before overlays, as suggested by comments.
2207 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
2208 Remove redundant check before calling offset_intervals.
2210 2012-09-14 Martin Rudalics <rudalics@gmx.at>
2212 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
2213 current buffer (Bug#12387).
2215 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
2217 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
2219 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
2221 Use a more backwards-compatible timer format (Bug#12430).
2222 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
2223 vector element, not from the 4th, since PSECS is now at the end.
2224 (Fcurrent_idle_time): Doc fix.
2226 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
2228 Function to mark objects and remove killed buffers at once.
2229 * alloc.c (discard_killed_buffers): Rename to ...
2230 (mark_discard_killed buffers) ... new name. Add marking
2231 of remaining objects. Fix comment. Adjust users.
2232 (mark_object): Do not touch frame buffer lists here.
2233 * frame.c (delete_frame): Reset frame buffer lists here.
2235 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
2237 Better workaround for GNOME bug when --enable-gcc-warnings.
2238 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
2239 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
2240 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
2242 Simplify SIGIO usage (Bug#12408).
2243 The code that dealt with SIGIO was crufty and confusing, e.g., it
2244 played tricks like "#undef SIGIO" but these tricks were not used
2245 consistently. Simplify mostly by not #undeffing standard symbols,
2246 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
2247 or not as we please) rather than "defined SIGIO" (standard symbol
2248 that we probably shouldn't #undef).
2249 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
2250 Modules that need it can include it.
2251 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
2252 * dispextern.h (ignore_sigio): New decl.
2253 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
2254 unconditionally, since it's now a no-op if !USABLE_SIGIO.
2255 * emacs.c (shut_down_emacs):
2256 * keyboard.c (kbd_buffer_store_event_hold):
2257 Use ignore_sigio rather than invoking 'signal' directly.
2258 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
2260 (FIONREAD, SIGIO): Do not #undef.
2261 (tty_read_avail_input): Use #error rather than a syntax error.
2262 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
2263 for I_PIPE, used by SETUP_SLAVE_PTY.
2264 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
2265 * sysdep.c (croak): Remove; no longer needed. This bit of
2266 temporary code, with Fred N. Fish's comment that it's temporary,
2267 has been in Emacs since at least 1992!
2268 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
2269 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
2270 * syssignal.h (croak): Remove decl.
2271 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
2272 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
2273 now that we're termios-only.
2274 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
2275 * term.c (dissociate_if_controlling_tty): Use #error rather than
2278 Work around GCC and GNOME bugs when --enable-gcc-warnings.
2279 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
2280 to work around GNOME bug 683906.
2281 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
2282 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
2283 This works around GCC bug 54561.
2285 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
2287 More fixes for 'volatile' and setjmp/longjmp.
2288 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
2289 * image.c (struct png_load_context) [HAVE_PNG]: New type.
2290 (png_load_body) [HAVE_PNG]:
2291 (jpeg_load_body) [HAVE_JPEG]:
2292 New function, with most of the old parent function's body.
2293 (png_load) [HAVE_PNG]:
2294 (jpeg_load) [HAVE_JPEG]:
2295 Invoke the new function, to avoid longjmp munging our locals.
2296 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
2297 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
2298 longjmp is passed 2, as the C standard doesn't guarantee this.
2299 Instead, store the failure code into mgr->failure_code.
2301 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
2303 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
2304 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
2305 (syms_of_keyboard): Remove support for unread-command-char.
2307 2012-09-12 Eli Zaretskii <eliz@gnu.org>
2309 * w32proc.c (sys_kill): If PID is our process ID and the signal is
2310 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
2311 violation. (Bug#12426)
2313 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
2315 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
2317 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
2319 * eval.c: Add `inhibit-debugger'.
2320 (Qinhibit_debugger): New symbol.
2321 (call_debugger): Bind it instead of Qdebug_on_error.
2322 (maybe_call_debugger): Test Vinhibit_debugger.
2323 (syms_of_eval): Define inhibit-debugger.
2324 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
2325 (syms_of_xdisp): Remove inhibit-debug-on-message.
2327 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
2329 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
2330 If a nonvolatile local variable is written before a _longjmp to
2331 the frame containing the variable, and is read after the _longjmp,
2332 the value read is indeterminate. Some local variables of type
2333 'struct handler' and 'struct catchtag' are used in this way, so
2334 mark each of their slots as volatile if the slot can be set before
2335 _longjmp and read afterwards.
2336 * lisp.h (struct handler): var and chosen_clause are now volatile.
2337 (struct catchtag): val, next, and pdlcount are now volatile.
2339 * bidi.c (bidi_push_it, bidi_pop_it):
2340 * fns.c (copy_hash_table):
2341 * image.c (define_image_type):
2342 * keyboard.c (kbd_buffer_store_event_hold):
2343 * process.c (Fprocess_send_eof):
2344 * xfaces.c (x_create_gc) [HAVE_NS]:
2345 * xgselect.c (xg_select):
2346 Prefer assignment to memcpy when either will do.
2348 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
2349 Use pointer-to-a-pointer to simplify and avoid a NILP check each
2350 time an item is removed. No need to mark this function 'inline';
2351 the compiler knows better than we do.
2353 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
2355 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
2356 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
2357 to change_frame_size (Bug#12388).
2358 (windowDidResize:): Pass YES to updateFrameSize.
2360 * nsterm.h: Add delay parameter to updateFrameSize.
2362 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
2364 Discard killed buffers from deleted window and frame objects.
2365 This reduces an amount of references to killed buffers and
2366 helps GC to reclaim them faster.
2367 * alloc.c (discard_killed_buffers): New function.
2368 (mark_object): Use it for deleted windows and frames.
2369 (mark_object): If symbol's value is set up for a killed buffer
2370 or deleted frame, restore its global binding.
2371 * data.c (swap_in_global_binding): Add GC notice.
2372 (swap_in_symval_forwarding): Use convenient set_blv_where.
2373 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
2374 * window.h: ... to here.
2376 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
2378 Convenient macro to check whether the buffer is live.
2379 * buffer.h (BUFFER_LIVE_P): New macro.
2380 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
2381 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
2383 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2385 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
2386 composition cases (Bug#12364).
2388 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
2389 overhang of succeeding glyphs overlapping box cursor.
2391 * w32term.c (x_draw_glyph_string): Likewise.
2393 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
2395 Simplify, document, and port floating-point (Bug#12381).
2396 The porting part of this patch fixes bugs on non-IEEE platforms
2397 with frexp, ldexp, logb.
2398 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
2400 * floatfns.c: Simplify discussion of functions that Emacs doesn't
2401 support, by removing commented-out code and briefly listing the
2402 C89 functions excluded. The commented-out stuff was confusing
2403 maintenance, e.g., we thought we needed cbrt but it was commented out.
2404 (logb): Remove decl; no longer needed.
2405 (isfinite): New macro, if not already supplied.
2406 (isnan): Don't replace any existing macro.
2407 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
2408 are present on all C89 platforms.
2409 (Ffrexp): Do not special-case zero, as frexp does the right thing
2411 (Flogb): Do not use logb, as it doesn't have the desired meaning
2412 on hosts that use non-base-2 floating point. Instead, stick with
2413 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
2414 frexp, to avoid getting an unspecified result.
2416 * xdisp.c (Qinhibit_debug_on_message): Now static.
2418 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
2420 * nsterm.m (ns_update_begin): Set clip path to whole view by using
2421 NSBezierPath (Bug#12131).
2423 2012-09-10 Chong Yidong <cyd@gnu.org>
2425 * fns.c (Fdelq, Fdelete): Doc fix.
2427 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
2429 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
2430 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
2432 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
2434 * lisp.h (make_lisp_ptr): New macro to replace XSET.
2435 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
2438 2012-09-09 Eli Zaretskii <eliz@gnu.org>
2440 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
2441 left fringe if the window has a left margin. This avoids leaving
2442 traces of the cursor because its leftmost pixel is not drawn over.
2444 * dispnew.c (update_window_line): When the left margin area of a
2445 screen line is updated, set the redraw_fringe_bitmaps_p flag of
2446 that screen line. (Bug#12277)
2448 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
2450 Assume C89 or later for math functions (Bug#12381).
2451 This simplifies the code, and makes it a bit smaller and faster,
2452 and (most important) makes it easier to clean up signal handling
2453 since we can stop worring about floating-point exceptions in
2454 library code. That was a problem before C89, but the problem
2455 went away many years ago on all practical Emacs targets.
2456 * data.c, image.c, lread.c, print.c:
2457 Don't include <math.h>; no longer needed.
2458 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
2459 might be autoconfigured, as that never happens.
2461 * doprnt.c (DBL_MAX_10_EXP):
2462 * print.c (DBL_DIG):
2463 Remove. C89 or later always defines these.
2464 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
2465 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
2466 (arith_error, domain_error, domain_error2):
2467 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
2468 no longer needed -- we simply return what C returns. All uses removed.
2469 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
2471 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
2472 Remove. All uses expanded, as these macros are no longer used
2473 more than once and are now more trouble than they're worth.
2474 (Ftan): Use tan, not sin / cos.
2475 (Flogb): Assume C89 frexp.
2476 (fmod_float): Assume C89 fmod.
2477 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
2478 (init_floatfns): Remove. All uses removed.
2480 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
2482 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
2483 compositeToPoint for OSX < 10.6 (Bug#12390).
2485 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
2487 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
2488 This produces more-accurate results.
2490 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
2492 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
2493 changes (Bug#12088).
2495 2012-09-08 Chong Yidong <cyd@gnu.org>
2497 * syntax.c (Fstring_to_syntax): Doc fix.
2499 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
2501 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
2502 in the internal border.
2503 (x_set_window_size): Remove static variables and their usage.
2504 (ns_redraw_scroll_bars): Fix NSTRACE arg.
2505 (ns_after_update_window_line, ns_draw_fringe_bitmap):
2506 Remove fringe/internal border adjustment (Bug#11052).
2507 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
2508 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
2509 (ns_fix_rect_ibw): Remove.
2510 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
2511 (ns_dumpglyphs_box_or_relief): Ditto.
2512 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
2514 (ns_dumpglyphs_image): Ditto.
2515 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
2517 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
2518 their usage. Add fringe_extended_p and its use as in other terms.
2519 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
2520 scroll bar was removed.
2521 (updateFrameSize): New function.
2522 (windowDidResize): Move code to updateFrameSize and call it.
2524 * nsterm.h (EmacsView): Add updateFrameSize.
2526 2012-09-07 Chong Yidong <cyd@gnu.org>
2528 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
2530 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
2532 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
2534 More signal-handler cleanup (Bug#12327).
2535 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
2536 Problem introduced when merging patches. Noted by Eli Zaretskii in
2537 <http://bugs.gnu.org/12327#67>.
2538 * floatfns.c: Comment fix.
2539 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
2540 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
2541 and anyway the declaration is harmless even if SIGDANGER is not defined.
2542 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
2543 defined BROKEN_FIONREAD). systty.h formerly did this, but other
2544 source files not surprisingly expected syssignal.h to define, or
2545 not define, SIGIO, and it's cleaner to do it that way, for consistency.
2546 Include <sys/ioctl.h>, for FIONREAD.
2547 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
2548 This eliminates a problem whereby other files mysteriously had
2549 to include "syssignal.h" before including "systty.h" if they
2550 wanted to use "#ifdef SIGIO".
2552 2012-09-07 Eli Zaretskii <eliz@gnu.org>
2554 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
2556 * w32.c (sigemptyset): Empty the set.
2557 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
2559 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
2561 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
2563 * alloc.c (mark_buffer): Revert unsafe marking optimization.
2564 (mark_object): Likewise for frame objects.
2566 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
2568 * syssignal.h (handle_on_main_thread): Always declare,
2569 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
2570 This ports to platforms without HAVE_PTHREAD.
2572 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
2574 Signal-handler cleanup (Bug#12327).
2575 Emacs's signal handlers were written in the old 4.2BSD style with
2576 sigblock and sigmask and so forth, and this led to some
2577 inefficiencies and confusion. Rewrite these to use
2578 pthread_sigmask etc. without copying signal sets around. Also,
2579 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
2580 'signal', and instead use functions that do not attempt to take
2581 over the system name space. This patch causes Emacs's text
2582 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
2583 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
2584 Do not include <signal.h> or "syssignal.h", as these
2585 modules do not use signals.
2586 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
2587 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
2588 Do not include <signal.h>, as "syssignal.h" does that for us now.
2589 * atimer.c (sigmask_atimers): New function.
2590 (block_atimers, unblock_atimers): New functions,
2591 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
2593 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
2594 no longer needed here.
2595 * emacs.c (main): Inspect existing signal handler with sigaction,
2596 so that there's no need to block and unblock SIGHUP.
2597 * sysdep.c (struct save_signal): New member 'action', replacing
2598 old member 'handler'.
2599 (save_signal_handlers, restore_signal_handlers):
2600 Use sigaction instead of 'signal' to save and restore.
2601 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
2602 New function. All users of 'signal' modified to use set_sighandler
2603 if they're writeonly, and to use sys_signal if they're read+write.
2604 (emacs_sigaction_init, forwarded_signal): New functions.
2605 (sys_signal): Remove. All uses replaced by calls to sigaction
2606 and emacs_sigaction_init, or by direct calls to 'signal'.
2607 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
2608 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
2609 all uses replaced by pthread_sigmask etc. calls.
2610 * syssignal.h: Include <signal.h>.
2611 (emacs_sigaction_init, forwarded_signal): New decls.
2612 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
2613 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
2614 (sigmask, sys_sigmask): Remove; no longer needed.
2615 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
2616 (sigblock, sigunblock, sigfree):
2617 (sigsetmask) [!defined sigsetmask]:
2618 Remove. All uses replaced by pthread_sigmask.
2619 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
2620 no longer need to be replaced, and its typical old uses
2621 are now done via emacs_sigaction_init and sigaction.
2622 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
2623 (sys_sigdel): Remove; unused.
2624 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
2626 2012-09-06 Eli Zaretskii <eliz@gnu.org>
2628 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
2629 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
2631 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
2633 Explicitly mark buffer_defaults and buffer_local_symbols.
2634 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
2635 mark_local_symbols here.
2636 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
2637 since special buffers aren't marked here any more.
2638 (allocate_buffer): Chain new buffer with all_buffers here...
2639 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
2641 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
2642 (syms_of_buffer): Remove staticpro of the above.
2643 (init_buffer_once): Set names for buffer_defaults and
2644 buffer_local_symbols.
2646 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
2648 Use bool for booleans in font-related modules.
2649 * font.c (font_intern_prop, font_style_to_value)
2650 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
2651 (generate_otf_features, font_check_otf_features, font_check_otf)
2652 (font_match_p, font_list_entities, font_at):
2653 * fontset.c (fontset_id_valid_p, reorder_font_vector
2654 (fontset_find_font, Fset_fontset_font)
2655 (face_suitable_for_char_p) [0]:
2656 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
2657 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
2658 (m17n_flt_initialized, ftfont_shape_by_flt):
2659 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
2660 * nsfont.m (nsfont_draw):
2661 * w32font.c (w32font_draw):
2662 * w32term.c (x_draw_glyphless_glyph_string_foreground):
2663 Use bool for booleans.
2664 * font.h: Adjust to above API changes.
2665 (struct font, struct font_driver, struct font_driver_list):
2666 Use bool for booleans.
2667 (struct font): Remove useless member encoding_type.
2669 * fontset.c, xftfont.c: Omit unnecessary static decls.
2671 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
2673 * alloc.c (mark_object): Revert window marking code
2674 since it's unsafe for the Fset_window_configuration.
2676 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
2678 Fix race conditions with signal handlers and errno (Bug#12327).
2679 Be more systematic about preserving errno whenever a signal
2680 handler returns, even if it's not in the main thread. Do this by
2681 renaming signal handlers to distinguish between signal delivery
2682 and signal handling. All uses changed.
2683 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
2684 * data.c (deliver_arith_signal): Rename from arith_error.
2685 * dispnew.c (deliver_window_change_signal): Rename from
2686 window_change_signal.
2687 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
2688 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
2689 * keyboard.c (deliver_input_available_signal): Rename from
2690 input_available_signal.
2691 (deliver_user_signal): Rename from handle_user_signal.
2692 (deliver_interrupt_signal): Rename from interrupt_signal.
2693 * process.c (deliver_pipe_signal): Rename from send_process_trap.
2694 (deliver_child_signal): Rename from sigchld_handler.
2695 * atimer.c (handle_alarm_signal):
2696 * data.c (handle_arith_signal):
2697 * dispnew.c (handle_window_change_signal):
2698 * emacs.c (handle_fatal_signal, handle_danger_signal):
2699 * keyboard.c (handle_input_available_signal):
2700 * keyboard.c (handle_user_signal, handle_interrupt_signal):
2701 * process.c (handle_pipe_signal, handle_child_signal):
2702 New functions, with the actual signal-handling code taken from the
2703 original respective signal handlers, sans the sporadic attempts to
2704 preserve errno, since that's now done by handle_on_main_thread.
2705 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
2706 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
2707 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
2709 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
2710 Move initialization of main_thread to sysdep.c's init_signals.
2711 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
2712 our usage, and simplifies the mainline code.
2713 (record_child_status_change): New static function, as a helper
2714 for handle_child_signal, and with most of the old child handler's
2716 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
2717 (handle_child_signal): Use the above.
2718 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
2719 Moved here from emacs.c.
2720 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
2721 code moved here from emacs.c's main function.
2722 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
2723 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
2724 This lets callers save and restore errno properly.
2726 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
2728 Remove redundant or unused things here and there.
2729 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
2730 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
2731 * editfns.c (Fcompare_buffer_substrings): Likewise.
2732 * frame.h (struct terminal, struct font_driver_list):
2733 Remove redundant declarations.
2734 * window.h (Qleft, Qright): Likewise.
2736 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
2738 Do not mark objects from deleted buffers, windows and frames.
2739 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
2740 (mark_object): Likewise for windows and frames.
2742 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
2744 * alloc.c (valid_lisp_object_p): Treat killed buffers,
2745 buffer_defaults and buffer_local_symbols as valid objects.
2746 Return special value to denote them.
2748 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
2750 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
2751 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
2752 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
2753 (file_name_absolute_p, Fsubstitute_in_file_name):

2756 (Finsert_file_contents, choose_write_coding_system)
2757 (Fwrite_region, build_annotations, a_write, e_write)
2759 * filelock.c (boot_time_initialized, get_boot_time)
2760 (get_boot_time_1, lock_file_1, within_one_second):
2761 * floatfns.c (in_float):
2762 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
2763 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
2764 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
2765 * lisp.h (struct Lisp_Hash_Table.cmpfn):
2766 * window.c (compare_window_configurations):
2767 Use bool for booleans.
2768 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
2769 (Fdefault_file_modes): Now mode_t, not int, for modes.
2770 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
2771 (internal_delete_file): Now returns void, not a (boolean) int,
2772 since nobody was looking at the return value.
2773 * lisp.h, window.h: Adjust to above API changes.
2775 * xdisp.c (set_message): Simplify and reindent last change.
2777 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
2779 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
2781 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
2783 * eval.c (call_debugger): Make the function non-static so that we
2784 can call it from set_message.
2786 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
2787 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
2789 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
2791 Give more-useful info on a fatal error (Bug#12328).
2792 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
2793 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
2794 of doing the work ourselves.
2795 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
2796 do most of the work.
2797 (fatal_error_backtrace): New function, taken from the guts
2798 of the old fatal_error_signal, but with a new option to output
2800 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
2801 info about the signal than just its number.
2802 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
2803 * sysdep.c: Include <execinfo.h>
2804 (emacs_backtrace): New function, taken partly from the previous
2805 code of the 'die' function.
2806 (emacs_abort): Call fatal_error_backtrace rather than abort.
2808 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
2810 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
2811 eager (load-time) macro-expansion.
2812 * lisp.mk (lisp): Add macroexp.
2814 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
2816 Simplify redefinition of 'abort' (Bug#12316).
2817 Do not try to redefine the 'abort' function. Instead, redo
2818 the code so that it calls 'emacs_abort' rather than 'abort'.
2819 This removes the need for the NO_ABORT configure-time macro
2820 and makes it easier to change the abort code to do a backtrace.
2821 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
2822 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
2823 Remove; sysdep.c's emacs_abort now takes its place.
2824 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
2825 'abort' changed to use 'emacs_abort'.
2826 * msdos.c (dos_abort) [defined abort]: Remove; not used.
2827 (abort) [!defined abort]: Rename to ...
2828 (emacs_abort): ... new name.
2829 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
2830 the place of the old 'abort' in emacs.c.
2831 * w32.c, w32fns.c (abort): Do not #undef.
2832 * w32.c (emacs_abort): Rename from w32_abort.
2834 2012-09-04 Eli Zaretskii <eliz@gnu.org>
2836 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
2837 offsets[j].dv, since the y axis of the screen coordinates points
2838 down, while the y axis of the font definition coordinates points
2839 up. This fixes display of Arabic diacritics such as KASRA and
2840 KASRATAN. (Bug#11860)
2842 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
2844 Be more systematic about _setjmp vs setjmp.
2845 * alloc.c (test_setjmp, mark_stack):
2846 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
2847 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
2848 (png_load, my_error_exit, jpeg_load):
2849 * process.c (send_process_trap, send_process):
2850 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
2851 The underscored versions are up to 30x faster on some hosts.
2852 Formerly, the code used setjmp+longjmp sometimes and
2853 _setjmp+_longjmp at other times, with no particular reason to
2854 prefer setjmp+longjmp.
2856 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
2858 Fix minor problem found by static checking.
2859 * buffer.c (Fdelete_all_overlays): Return nil.
2861 2012-09-03 Martin Rudalics <rudalics@gmx.at>
2863 * buffer.c (Fdelete_all_overlays): New function.
2865 2012-09-03 Chong Yidong <cyd@gnu.org>
2867 * gtkutil.c: Add extern decl for Qxft.
2869 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>

2883 All callers changed.
2884 * eval.c (interactive_p): Omit always-true boolean argument
2885 EXCLUDE_SUBRS_P. All callers changed.
2886 * dispextern.h, lisp.h: Reflect above API changes.
2887 * firstfile.c (dummy): Use the address of 'main', whose signature
2888 won't change, instead of the address of 'initialize', whose
2889 signature just changed from int to bool.
2890 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
2891 * msdos.c (fatal_error_in_progress): ... from here.
2892 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
2894 (redisplay_internal, unwind_redisplay): Simply clear
2895 REDISPLAYING_P when unwinding, instead of saving its previous,
2896 always-false value and then restoring it.
2898 Clean up some extern decls.
2899 Mostly, this hoists extern decls out of .c files and into .h files.
2900 That way, we're more likely to catch errors if the interfaces change.
2901 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
2902 declare xg_mark_data.
2903 * dispextern.h (x_frame_parm_handlers):
2905 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
2906 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)

2921 * xfont.c (x_clear_errors):
2922 * xterm.c (x_frame_parm_handlers):
2923 Remove now-redundant extern decls.
2924 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
2925 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
2927 * xfaces.c: Remove unnecessary static decls.
2928 * xterm.c (updating_frame): Remove decl of nonexistent object.
2930 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
2931 when building globals.h, as the objects that are not built on
2932 this host are not needed to compile C files on this host.
2934 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
2936 * gtkutil.h: Remove prototype for x_wm_set_size_hint.

2963 (set_intervals_multibyte_1, set_intervals_multibyte):
2964 * keyboard.c (decode_timer):
2965 Use bool for boolean.
2966 * intervals.h, lisp.h, systime.h: Reflect above API changes.
2967 * editfns.c (struct info): Use 1-bit unsigned bitfields for booleans.

2974 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
2976 * makefile.w32-in (CCL_H, W32FONT_H): New macros.

2984 2012-09-01 Eli Zaretskii <eliz@gnu.org>
2986 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
2987 more than one grapheme cluster passed to the shaper: compute the
2988 offset adjustment values separately for each cluster. (Bug#11860)
2990 * image.c: Restore mistakenly removed inclusion of w32.h. Without
2991 it, GCC doesn't see prototypes of w32_delayed_load, and complains
2992 about implicit conversions from integer to pointer.
2994 2012-09-01 Daniel Colascione <dancol@dancol.org>
2996 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
2997 system used too early.
2999 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
3001 Better seed support for (random).

3043 window-system headers.

3050 window system declarations.
3052 * frame.h: Move common functions here: set_frame_menubar,
3053 x_set_window_size, x_sync, x_get_focus_frame,
3054 x_set_mouse_position, x_set_mouse_pixel_position,
3055 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

3079 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
3081 Remove mark_ttys function and fix tty_display_info initialization.
3082 * lisp.h (mark_ttys): Remove prototype.
3083 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
3084 to mark_ttys because all possible values of 'top_frame' slot are
3085 the frames which are reachable from Vframe_list.
3086 * term.c (mark_ttys): Remove.
3087 (init_tty): Safely initialize 'top_frame' slot with Qnil.
3089 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>

3094 'auto_raise', 'auto_lower', 'no_split', 'explicit_name',
3095 'window_sizes_changed', 'mouse_moved' and 'pointer_invisible'
3096 bitfields from unsigned char to unsigned.

3111 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
3112 for GCC 4.7.1 x86-64.
3114 2012-08-30 Glenn Morris <rgm@gnu.org>
3116 * lread.c (init_lread): For out-of-tree builds, only add the
3117 source directory's site-lisp dir to the load-path if it exists,
3118 consistent with in-tree builds. (Bug#12302)
3120 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>
3122 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize

3132 (addSplit): Remove return self, declare return value as void.
3133 (clicked:): Remove return self, declare return value as void.
3134 Set dialog_return to button_values[seltag]. Code formatting change.

3136 Code formatting change.
3137 (timeout_handler:): Set timer_fired to YES.
3138 (runDialogAt:): Set timer_fired to NO.
3139 Handle click on close button as quit.
3141 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
3142 Add window_closed and button_values. Add void as return value for
3143 add(Button|String|Split). addButton takes int instead of Lisp_Object.
3144 Add process_dialog as new member.
3146 2012-08-28 Eli Zaretskii <eliz@gnu.org>
3148 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it

3214 * dispextern.h, frame.h, lisp.h: Reflect above API changes.
3215 * dispextern.h (struct composition_it): Use bool for boolean.
3216 (struct glyph_matrix): Don't assume buffer sizes can fit in 'int'.
3217 (struct bidi_it): Use unsigned:1, not int, for boolean prev_was_pdf.
3218 * dired.c (file_name_completion):
3219 Use bool for boolean. (This was missed in an earlier change.)
3221 2012-08-27 Martin Rudalics <rudalics@gmx.at>
3223 * window.c (Fset_window_configuration): Revert first part of
3226 2012-08-27 Jan Djärv <jan.h.d@swipnet.se>
3228 * nsterm.h (NSPanel): New class variable dialog_return.
3230 * nsmenu.m (initWithContentRect:styleMask:backing:defer:):
3231 Initialize dialog_return.
3232 (windowShouldClose:): Use stop instead of stopModalWithCode.
3233 (clicked:): Ditto, and also set dialog_return (Bug#12258).
3234 (timeout_handler:): Use stop instead of abortModal. Send a dummy
3236 (runDialogAt:): Make ret Lisp_Object. Set it from dialog_return when
3239 2012-08-27 Paul Eggert <eggert@cs.ucla.edu>
3241 * composite.c, data.c, dbusbind.c, dired.c: Use bool for booleans.
3242 * composite.c (find_composition, composition_gstring_p)
3243 (composition_reseat_it, find_automatic_composition):
3244 * data.c (let_shadows_buffer_binding_p)
3245 (let_shadows_global_binding_p, set_internal, make_blv)
3246 (Fmake_variable_buffer_local, Fmake_local_variable)
3247 (Fmake_variable_frame_local, arithcompare, cons_to_unsigned)
3248 (cons_to_signed, arith_driver):
3249 * dbusbind.c (xd_in_read_queued_messages):
3250 * dired.c (directory_files_internal, file_name_completion):
3251 Use bool for booleans.
3252 * dired.c (file_name_completion):
3253 * process.h (fd_callback):
3254 Omit int (actually boolean) argument. It wasn't being used.
3256 * composite.h, lisp.h: Reflect above API changes.
3258 * cmds.c, coding.c: Use bool for booleans.
3259 * cmds.c (move_point, Fself_insert_command):
3260 * coding.h (struct composition status, struct coding_system):
3261 * coding.c (detect_coding_utf_8, encode_coding_utf_8)
3262 (detect_coding_utf_16, encode_coding_utf_16, detect_coding_emacs_mule)
3263 (emacs_mule_char, decode_coding_emacs_mule)

3265 (decode_coding_iso_2022, encode_invocation_designation)
3266 (encode_designation_at_bol, encode_coding_iso_2022)

3277 (Funencodable_char_position, code_convert_region)
3278 (code_convert_string, code_convert_string_norecord)
3279 (Fset_coding_system_priority):
3280 * fileio.c (Finsert_file_contents):
3281 Use bool for booleans.
3282 * coding.h, lisp.h: Reflect above API changes.
3283 * coding.c: Remove unnecessary static function decls.
3284 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
3285 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
3286 not a boolean 'int', since callers never look at the return value.
3287 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
3288 * coding.h (decoding_buffer_size, encoding_buffer_size)
3289 (emacs_mule_string_char): Remove unused extern decls.
3290 (struct iso_2022_spec, struct coding_system):
3291 Use 'unsigned int : 1' for boolean fields, since there's more than one.
3292 (struct emacs_mule_spec): Remove unused field 'full_support'.
3293 All initializations removed.
3294 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
3296 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
3298 Fix spare memory change (Bug#12286).
3299 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
3300 (valid_lisp_object_p): Likewise.
3302 2012-08-27 Martin Rudalics <rudalics@gmx.at>
3304 * window.c (Fset_window_configuration): Record any window's old
3305 buffer if it's replaced (see Bug#8789). If the new current
3306 buffer doesn't appear in the selected window, go to its old
3309 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
3311 Special MEM_TYPE_SPARE to denote reserved memory.
3312 * alloc.c (enum mem_type): New memory type.
3313 (refill_memory_reserve): Use new type for spare memory.
3314 This prevents live_cons_p and live_string_p from incorrect
3315 detection of uninitialized objects from spare memory as live.
3317 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
3320 * Makefile.in (.PHONY): versioclean -> versionclean.
3322 Remove unused external symbols.
3323 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
3324 * window.c (Qwindow_valid_p, decode_valid_window):
3325 Now static, not extern.
3326 * data.c (Qinterval): Remove; unused.
3327 (syms_of_data): Do not define 'interval'.
3328 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
3329 * window.h (decode_valid_window):
3332 * character.c, charset.c, chartab.c: Use bool for booleans.
3333 * character.c (lisp_string_width, string_count_byte8)
3334 (string_escape_byte8):
3335 * charset.c (charset_map_loaded, load_charset_map, read_hex):
3336 (load_charset_map_from_file, map_charset_chars)
3337 (Fdefine_charset_internal, define_charset_internal)
3338 (Fdeclare_equiv_charset, find_charsets_in_text)
3339 (Ffind_charset_region, char_charset, Fiso_charset):
3340 * chartab.c (sub_char_table_ref, sub_char_table_ref_and_range)
3341 (sub_char_table_set, sub_char_table_set_range)
3342 (char_table_set_range, optimize_sub_char_table)
3343 (map_sub_char_table):
3344 Use bool for boolean.
3345 * character.c (str_to_unibyte): Omit last boolean argument; it was
3346 always 0. All callers changed.
3347 * character.h, charset.h: Adjust to match previous changes.
3348 * character.h (char_printable_p): Remove decl of nonexistent function.
3349 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
3350 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
3351 are all boolean, so make them single-bit bitfields.
3353 * lisp.h (ASET): Remove attempt to detect side effects.
3354 It was meant to be temporary and it often doesn't work,
3355 because when IDX has side effects the behavior of IDX==IDX
3356 is undefined. See Stefan Monnier in
3357 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
3359 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
3361 * lisp.h (functionp): New function (extracted from Ffunctionp).
3362 (FUNCTIONP): Use it.
3363 * eval.c (Ffunctionp): Use it.
3365 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
3367 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
3368 as that's faster and simpler than static storage. Don't bother
3369 with the g_main_context_query overhead if g_main_context_pending
3370 says no events are pending.
3371 (gfds, gfds_size): Remove these static vars.
3372 (xgselect_initialize): Remove; no longer needed.
3373 All uses and decls removed.
3375 * emacs.c (fatal_error_signal_hook): Remove.
3376 All uses removed. This leftover from old code was always 0.
3378 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
3379 * casefiddle.c (casify_object, casify_region):
3380 * casetab.c (set_case_table):
3381 * category.c, category.h (word_boundary_p):
3382 * category.h (CHAR_HAS_CATEGORY):
3383 Use bool for booleans, instead of int.
3385 2012-08-25 Eli Zaretskii <eliz@gnu.org>
3387 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
3389 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
3391 On assertion failure, print backtrace if available.
3392 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
3393 (die) [ENABLE_CHECKING]: Print a backtrace if available.
3394 * Makefile.in (LIB_EXECINFO): New macro.
3397 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
3398 * bytecode.c (exec_byte_code):
3399 * callint.c (check_mark, Fcall_interactively):
3400 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
3401 (getenv_internal, sync_process_alive, call_process_exited):
3402 * lisp.h (USE_SAFE_ALLOCA):
3403 Use bool for booleans, instead of int.
3404 * lisp.h, process.h: Adjust prototypes to match above changes.
3405 * callint.c (Fcall_interactively): Don't assume the mark's
3406 offset fits in 'int'.
3408 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
3410 * buffer.c, buffer.h: Use bool for boolean.
3411 * buffer.c (reset_buffer_local_variables)
3412 (buffer_lisp_local_variables, Fset_buffer_modified_p)
3413 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
3414 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
3415 (overlay_touches_p, overlay_strings, Foverlay_put)
3416 (report_overlay_modification, call_overlay_mod_hooks):
3417 (mmap_enlarge, mmap_set_vars):
3418 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
3419 Use bool for booleans, instead of int.
3420 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
3421 since the 1-or-0 return value is always ignored anyway.
3422 (mmap_initialized_p):
3423 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
3424 * buffer.h, lisp.h: Adjust prototypes to match above changes.
3426 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
3428 * bidi.c: Use bool for boolean.
3429 This is a bit more readable, and makes the text segment of bidi.o
3430 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
3431 Presumably it's faster too.
3432 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
3434 (bidi_cache_find_level_change, bidi_cache_iterator_state)
3435 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
3436 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
3437 (bidi_explicit_dir_char, bidi_level_of_next_char)
3438 (bidi_find_other_level_edge, bidi_move_to_visually_next):
3439 Use bool for booleans, instead of int.
3440 * dispextern.h (bidi_init_it, bidi_paragraph_init)
3441 (bidi_unshelve_cache): Adjust decls to match code.
3443 2012-08-23 Martin Rudalics <rudalics@gmx.at>
3445 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
3448 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
3450 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
3451 * atimer.h: Include <stdbool.h>.
3453 2012-08-22 Dan Nicolaescu <dann@gnu.org>
3455 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
3456 compile time tests instead of run time tests on systems that do
3458 (FRAME_MAC_P): Remove leftover from deleted code.
3459 * frame.c (syms_of_frame): Remove leftover from deleted code.
3461 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
3463 * nsterm.m (insertText:): Don't clear modifiers if code is space.
3465 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
3467 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
3468 Otherwise, the compiler complains about (A?B:C) where B is void
3469 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
3470 (fontset_add): Return void, for FONTSET_ADD.
3472 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
3474 * alloc.c: Use bool for booleans.
3475 (gc_in_progress, abort_on_gc)
3476 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
3477 (dont_register_blocks) [GC_MALLOC_CHECK]:
3478 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
3479 (check_string_bytes, make_specified_string, memory_full)
3480 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
3481 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
3482 (mark_stack, valid_pointer_p, make_pure_string)
3483 (Fgarbage_collect, survives_gc_p, gc_sweep):
3484 Use bool for booleans, instead of int.
3485 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
3486 Remove unused local.
3487 * alloc.c (PURE_POINTER_P):
3488 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
3489 * editfns.c (Fformat):
3490 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
3492 * fns.c (sweep_weak_table):
3493 * lisp.h (suppress_checking, push_message, survives_gc_p)
3494 (make_pure_string, gc_in_progress, abort_on_gc):
3495 * lread.c (readchar, read1):
3496 * print.c (Fprin1_to_string):
3497 * xdisp.c (push_message):
3498 Use bool for booleans affected directly or indirectly by
3501 Make recently-introduced setters macros.
3502 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
3503 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
3504 (set_fontset_default, set_fontset_fallback): Rename from their
3505 upper-case counterparts, and make them functions rather than macros.
3506 This is more consistent with the other recently-introduced setters.
3507 These don't need to be inline, since they're local.
3509 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
3511 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
3512 the loop (Bug#12247).
3514 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
3516 * lisp.h (vcopy): Use memcpy rather than our own loop.
3517 This fixes a performance regression introduced by the recent
3518 addition of vcopy. This means 'vcopy' will need to be modified
3519 for a copying collector, but that's OK. Also, tighten the
3520 checking in the assertion.
3522 2012-08-21 Eli Zaretskii <eliz@gnu.org>
3524 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
3525 components for RTL text (Bug#11860). Adjust X-OFFSET of each
3526 non-base glyph for the width of the base character, according to
3527 what x_draw_composite_glyph_string_foreground expects.
3528 Generate WADJUST value according to composition_gstring_width's
3529 expectations, to produce correct width of the composed character.
3530 Reverse the sign of the DU offset produced by ScriptPlace.
3532 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
3534 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
3536 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
3538 Avoid direct writes to contents member of struct Lisp_Vector.
3539 * lisp.h (vcopy): New function to copy data into vector.
3540 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
3541 * fns.c (Ffillarray): Use ASET.
3542 * keyboard.c (timer_check_2): Use AREF and ASET.
3543 (append_tool_bar_item, Frecent_keys): Use vcopy.
3544 * lread.c (read_vector): Use ASET.
3545 * msdos.c (Frecent_doskeys): Use vcopy.
3546 * xface.c (Finternal_copy_lisp_face): Use vcopy.
3547 (Finternal_merge_in_global_face): Use ASET and vcopy.
3548 * xfont.c (xfont_list_pattern): Likewise.
3550 2012-08-21 Martin Rudalics <rudalics@gmx.at>
3552 * window.c (Fwindow_point): For the selected window always return
3553 the position of its buffer's point.
3554 (Fset_window_point): For the selected window always go in its
3555 buffer to the specified position.
3557 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
3559 Setter macros for fontsets.
3560 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
3561 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
3562 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
3565 2012-08-20 Glenn Morris <rgm@gnu.org>
3567 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
3568 Don't assume that `ln -f' works.
3570 2012-08-20 Eli Zaretskii <eliz@gnu.org>
3572 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
3573 and later about non-assignments with no effect. See discussion at
3574 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
3577 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
3579 Inline setter functions for Lisp_Objects slots of struct specbinding.
3580 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
3583 2012-08-20 Martin Rudalics <rudalics@gmx.at>
3585 * window.c (select_window): Always make selected window's buffer
3588 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
3590 Use AREF and ASET for docstrings of category tables.
3591 * category.h (CATEGORY_DOCSTRING): Use AREF.
3592 (SET_CATEGORY_DOCSTRING): Use ASET.
3593 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
3595 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
3597 Inline setter functions for hash table members.
3598 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
3599 (set_hash_hash, set_hash_index): Rename with _slot suffix.
3600 (set_hash_key_and_value, set_hash_index, set_hash_next)
3601 (set_hash_hash): New functions.
3602 * charset.c, fns.c: Adjust users.
3604 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
3606 Inline getter and setter functions for per-buffer values.
3607 * buffer.h (per_buffer_default, set_per_buffer_default)
3608 (per_buffer_value, set_per_buffer_value): New functions.
3609 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
3610 * buffer.c, data.c: Adjust users.
3612 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
3614 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
3616 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
3618 Rely on <config.h> + <unistd.h> to declare 'environ',
3619 as gnulib does this if the system doesn't.
3620 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
3621 Remove declaration. MS-Windows declares it on stdlib.h which is
3622 included by conf_post.h.
3623 * emacs.c (environ) [DOUG_LEA_MALLOC]:
3624 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
3625 * vm-limit.c: Include <unistd.h>, for 'environ'.
3627 * unexaix.c, unexcoff.c: Include "mem-limits.h".
3628 (start_of_data): Remove decl; mem-limits.h provides it.
3630 * xdisp.c (handle_invisible_prop): Make it a bit faster
3631 and avoid a gcc -Wmaybe-uninitialized diagnostic.
3633 2012-08-19 Chong Yidong <cyd@gnu.org>
3635 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
3638 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
3640 * .gdbinit: Use call instead of set when calling a function in the
3643 * data.c (set_internal): Don't use set_blv_found.
3644 (Fkill_local_variable): Likewise.
3646 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
3648 * nsfont.m (ns_ascii_average_width): Ensure the string
3649 ascii_printable is initialized with a null-terminated character
3650 array. Otherwise, it can contain undesired extra characters.
3652 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
3654 port new setting code to Sun C 5.8 2005/10/13
3655 * chartab.c, lisp.h (char_table_set, char_table_set_range):
3656 Return void, not Lisp_Object. Otherwise, the compiler
3657 complains about (A?B:C) where B is void and C is Lisp_Object

4526 * lisp.h (DEFAULT_REHASH_THRESHOLD, DEFAULT_REHASH_SIZE):
4527 Now constants, not macros.
4529 2012-08-03 Paul Eggert <eggert@cs.ucla.edu>
4531 Remove unnecessary casts involving pointers.
4532 These casts are no longer needed now that we assume C89 or later,
4533 since they involve casting to or from void *.
4534 * alloc.c (make_pure_string, make_pure_c_string, pure_cons)
4535 (make_pure_float, make_pure_vector):
4536 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP):

4538 * menu.c (find_and_return_menu_selection):
4539 * minibuf.c (read_minibuf_noninteractive):
4540 * sysdep.c (closedir):
4541 * xdisp.c (x_produce_glyphs):
4542 * xfaces.c (compare_fonts_by_sort_order):
4543 * xfns.c (x_real_positions, select_visual):
4544 * xselect.c (x_stop_queuing_selection_requests)
4545 (x_get_window_property, x_get_window_property_as_lisp_data):
4546 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
4547 Remove unnecessary pointer casts.
4548 * alloc.c (record_xmalloc): New function.
4549 * lisp.h (record_xmalloc): New decl.
4550 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
4551 more like a function. This is because the pointer cast is not
4552 needed. All uses changed.
4553 * print.c (print_string, print_error_message): Avoid length recalc.
4555 Improve fix for macroexp crash with debugging (Bug#12118).
4556 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
4557 ARRAY_MARK_FLAG when checking subscripts, because ASET is
4558 not supposed to be invoked from the garbage collector.
4559 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
4560 (gc_aset): New function, which is like ASET but can be
4561 used in the garbage collector.
4562 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)
4563 (set_hash_index): Use it instead of ASET.
4565 2012-08-03 Eli Zaretskii <eliz@gnu.org>

4572 <g_b_init_create_symbolic_link>: New static flags.
4573 (globals_of_w32): Initialize them to zero.
4574 (GetSecurityInfo_Proc, CreateSymbolicLink_Proc): New typedefs.
4575 (map_w32_filename): Improve commentary. Simplify switch.
4576 (SYMBOLIC_LINK_FLAG_DIRECTORY): Define if not defined in system
4577 headers (most versions of MinGW w32api don't).
4578 (get_security_info, create_symbolic_link)
4579 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
4581 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
4582 in the argument file name.

4584 GetFileAttributes fails with network-related error codes.
4585 (sys_rename): Diagnose renaming of a symlink when the user doesn't
4586 have the required privileges.
4587 (get_file_security_desc_by_name): Rename from
4588 get_file_security_desc.
4589 (stat_worker): New function, with most of the guts of 'stat', and
4590 with addition of handling of symlinks and support for 'lstat'.
4591 If possible, get file's attributes and security information by
4592 handle, not by name. Produce S_IFLNK bit for symlinks, when
4593 called from 'lstat'.
4594 (stat, lstat): New functions, call 'stat_worker'.
4595 (symlink, readlink, careadlinkat): Rewritten to create and resolve
4596 symlinks when the underlying filesystem supports them.
4598 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
4600 Fix macroexp crash on Windows with debugging (Bug#12118).
4601 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
4602 checking subscripts; problem introduced with the recent
4603 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
4604 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
4605 since it's used in non-static inline functions now.
4607 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
4608 Don't assume buffer size fits in 'int'. Remove unused local.

4619 New macro, replacing 'static inline' in this header.
4620 * buffer.h, category.h, character.h, charset.h, composite.h:
4621 * dispextern.h, lisp.h, systime.h:
4622 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
4623 * alloc.c (LISP_INLINE):
4624 * buffer.c (BUFFER_INLINE):
4625 * category.c (CATEGORY_INLINE):
4626 * character.c (CHARACTER_INLINE):
4627 * charset.c (CHARSET_INLINE):
4628 * composite.c (COMPOSITE_INLINE):
4629 * dispnew.c (DISPEXTERN_INLINE):
4630 * sysdep.c (SYSTIME_INLINE):
4631 Define to EXTERN_INLINE, so that the corresponding functions
4632 are compiled into code.
4633 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
4634 (INLINE_HEADER_END): New macros.
4635 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,
4636 since it's used in non-static inline functions now.

4655 hard-coding the path separator.
4657 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
4659 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
4660 This how ASET and AREF are supposed to work, and makes
4661 it easier to think about future improvements. See
4662 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
4663 * charset.h (set_charset_attr): New function.
4664 All lvalue-style uses of CHARSET_DECODER etc. changed to use it.
4665 * lisp.h (ASET): Rewrite so as not to use AREF in an lvalue style.

4922 2012-07-30 Paul Eggert <eggert@cs.ucla.edu>

4937 (CHAR_TABLE_STANDARD_SLOTS, CHAR_TABLE_EXTRA_SLOTS):

5078 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
5079 enumeration constants, as PURE and HEAP are too general, and clash
5080 with other headers and sources, such as gmalloc.c and the
5081 MS-Windows system headers. All users changed.
5083 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
5085 Revert last save_excursion_save and save_excursion_restore changes.
5086 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

5099 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
5100 arms of an 'if', not using conditional expressions; otherwise GDB
5101 complains about the types in the unevaluated arm when the argument
5102 is an integer literal.
5103 (xgetint): Simplify expression.
5104 * alloc.c (gdb_make_enums_visible): New constant. This ports to
5105 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
5106 Zaretskii in <http://bugs.gnu.org/12036#13>.
5107 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
5108 needed now that we have gdb_make_enums_visible.
5109 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
5110 (enum enum_USE_LSB_TAG):
5111 New enum types, packaging up enums that need to be exported to GDB.

5153 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
5154 emacs.c, as this is a more-suitable home. Had this been done earlier
5155 the fix for 12036 would have avoided some of the problems noted in
5156 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
5157 would have been more obvious.
5158 * emacs.c: Do not include <verify.h>; no longer needed.
5159 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
5160 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
5161 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):

5167 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
5168 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
5169 not be usable in #if. This simplifies things.
5171 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
5173 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.

5178 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
5179 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
5180 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
5181 Adjust to changes in lisp.h and emacs.c, by using
5182 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
5183 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
5184 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
5185 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
5186 instead of gdb_valbits.
5187 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
5188 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
5189 instead of gdb_array_mark_flag.
5190 (xboolvector): Get size from $->size, not $->header.size.
5191 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
5192 (xreload, hook-run, hookpost-run): Remove.
5193 * emacs.c: Include <verify.h>.
5194 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
5195 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
5197 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
5198 (gdb_USE_LSB_TAG): New enum constants.
5199 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
5200 Also define these as enum constants, so they're visible to GDB.
5201 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
5202 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
5203 as constants, so they're visible to GDB.

5205 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
5206 Now enum constants, not macros, so they're visible to GDB.
5207 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
5208 more convenient now. All uses changed.
5209 (VALMASK) [USE_LSB_TAG]: Also define in this case.
5210 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
5212 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

5219 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
5220 add argument, tune behavior, and adjust all callers.
5222 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
5224 Use typedef for EMACS_INT, EMACS_UINT.
5225 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
5226 than macros. This simplifies debugging in the usual case, since
5227 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
5228 and it allows expressions involving EMACS_INT casts.
5229 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
5231 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

5241 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
5243 Adjust buffer text indirection counters at the end of Fkill_buffer.
5244 * buffer.c (Fkill_buffer): Adjust indirection counters when the
5245 buffer is definitely dead. This should really fix an issue reported
5246 by Christoph Scholtes again. (Bug#12007).
5247 (init_buffer_once): Initialize indirection counters of
5248 buffer_defaults and buffer_local_symbols (for sanity and safety).
5250 2012-07-24 Eli Zaretskii <eliz@gnu.org>
5252 * xdisp.c (init_iterator): Don't compute dimensions of truncation
5253 and continuation glyphs on tooltip frames, leave them at zero.

5281 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
5283 Swap buffer text indirection counters in Fbuffer_swap_text.
5284 * buffer.c (Fbuffer_swap_text): Swap indirections too.
5285 This avoids crash reported by Christoph Scholtes at
5286 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
5288 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
5290 * nsmenu.m (Popdown_data): New struct.
5291 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
5293 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
5294 (initWithContentRect): Make imgView and contentView non-static
5295 and autorelease them. Also autorelease img and matrix (Bug#12005).
5296 (dealloc): Remove (Bug#12005).
5298 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
5300 Adjust consing_since_gc when objects are explicitly freed.

5313 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
5315 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
5316 as it's limited by the amount of memory, not by INT_MAX.
5318 2012-07-21 Eli Zaretskii <eliz@gnu.org>
5320 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
5321 in special-event-map. See the discussion at

5380 * font.c (font_open_by_name): Change 2nd and 3rd args to the only arg
5381 of type Lisp_Object to avoid redundant calls to make_unibyte_string.
5382 Adjust users accordingly.
5383 * font.h (font_open_by_name): Adjust prototype.

5402 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
5403 'for_each_per_buffer_object_at'.

6044 * s/aix4-2.h (unix): Remove; no longer needed.
6046 EMACS_TIME simplification (Bug#11875).
6047 This replaces macros (which typically do not work in GDB)

6049 The functional style also makes code easier to read and maintain.
6050 * systime.h: Include <sys/time.h> on all hosts, not just if
6051 WINDOWSNT, since 'struct timeval' is needed in general.

6091 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
6092 Prefer snprintf to strncpy.
6093 * nsterm.m (ns_term_init):
6094 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
6095 * nsterm.m (ns_term_init):
6096 Avoid the need for strncpy, by using build_string or
6097 make_unibyte_string directly. Use dtoastr, not snprintf.
6098 * process.c (Fmake_network_process): Diagnose service names that
6099 are too long, rather than silently truncating them or creating
6100 non-null-terminated names.

6179 * lread.c [HAVE_NS]: Include nsterm.h.
6180 (init_lread) [HAVE_NS]: Use ns_load_path.

6190 (ns_init_paths): Do not set EMACSPATH.

6250 Move marker debugging code under MARKER_DEBUG.
6251 * marker.c (MARKER_DEBUG): Move marker debugging code under

6305 2012-07-07 Glenn Morris <rgm@gnu.org>
6307 * lread.c (load_path_check): New function, split from init_lread.
6308 (init_lread): Reorganize. Motivation:
6309 If EMACSLOADPATH is set, check/warn about that rather than the
6310 defaults, which we are not going to use. Hence we can remove
6311 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
6312 Don't warn if site-lisp directories are missing.
6313 If not installed, start from a blank load-path, since
6314 PATH_LOADSEARCH refers to the eventual installation directories.
6316 2012-07-07 Eli Zaretskii <eliz@gnu.org>
6318 Support truncation and continuation glyphs on GUI frames, when
6319 fringes are disabled. (Bug#11832)
6320 * xdisp.c (init_iterator): Get dimensions of truncation and
6321 continuation glyphs even if on GUI frames.
6322 Adjust it->last_visible_x on GUI frames when the left or right fringes,
6323 or both, are absent.
6324 (start_display, move_it_in_display_line_to): Handle the case of a
6325 GUI frame without a fringe to display continuation or truncation
6327 (insert_left_trunc_glyphs): Support GUI frames: make sure
6328 truncation glyphs overwrite enough glyphs from the current line to
6329 have sufficient space in pixels.
6330 (display_line): Support truncation and continuation glyphs on GUI
6331 frames. If some spare pixels are left on the line after inserting
6332 the truncation glyphs, fill that space with a stretch glyph of a
6333 suitably computed width.
6335 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
6336 produce_glyphs, to support GUI sessions.
6338 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
6340 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
6342 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
6344 Do not require float-time's arg to fit in time_t (Bug#11825).
6345 This works better on hosts where time_t is unsigned, and where
6346 float-time is applied to the (negative) difference between two times.
6347 * editfns.c (decode_time_components): Last arg is now double *,
6348 not int *, and means to store all the result as a double, without
6349 worrying about whether the seconds part fits in time_t.
6350 All callers changed.
6351 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
6352 All callers changed.
6353 (Ffloat_time): Do not fail merely because the specified time falls
6354 outside of time_t range.
6356 2012-07-07 Glenn Morris <rgm@gnu.org>
6358 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
6359 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
6360 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
6362 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
6364 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
6365 Update dependencies.
6367 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
6369 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
6371 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
6372 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
6373 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
6374 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
6375 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
6376 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
6378 * xfont.c (compare_font_names): Redo to omit the need for casts.
6380 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
6382 * xfns.c (Fx_change_window_property): Doc fix.
6383 * w32fns.c (Fx_change_window_property): Doc fix.
6385 * w32fns.c (Fx_window_property): Accept the same arguments as the
6386 X Windows version. Doc fix.
6387 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
6389 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
6390 Eli Zaretskii <eliz@gnu.org>
6392 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
6393 Windows-specific code from nt/config.nt moved here.
6394 Obsolete settings removed.
6396 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
6398 * process.c: Avoid unnecessary calls to gettime.
6399 (wait_reading_process_output): Don't get the time of day
6400 when gobbling data immediately and not waiting, as there's no need
6401 for it in that case. This removes a FIXME.
6403 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
6405 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
6406 is defined (Bug#11768).
6408 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6410 Fix marker debugging code.
6411 * marker.c (byte_char_debug_check): Do not perform the check
6412 if buffer is not multibyte.
6413 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
6414 Call byte_char_debug_check with correct arguments.
6416 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6418 Compile marker debugging code only if ENABLE_CHECKING is defined.
6419 * marker.c (byte_char_debug_check, count_markers):
6420 Use only if ENABLE_CHECKING is defined.
6421 (byte_debug_flag): Remove.
6422 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
6423 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
6425 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6427 Avoid code repetition in marker-related functions.
6428 * marker.c (attach_marker): New function.
6429 (Fset_marker, set_marker_restricted, set_marker_both)
6430 (set_marker_restricted_both): Use it.
6431 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
6432 Consistently rename charno to charpos.
6433 (marker_position): Add eassert.
6434 (marker_byte_position): Convert to eassert.
6436 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6438 Simplify list operations in unchain_overlay and unchain_marker.
6439 * buffer.c (unchain_overlay): Simplify. Add comment.
6440 * marker.c (unchain_marker): Simplify. Fix comments.
6442 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6444 Introduce fast path for the widely used marker operation.
6445 * alloc.c (build_marker): New function.
6446 * lisp.h (build_marker): New prototype.
6447 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
6448 * composite.c (autocmp_chars): Likewise.
6449 * editfns.c (buildmark): Remove.
6450 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
6451 (save_restriction_save): Use build_marker.
6452 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
6453 * window.c (save_window_save): Likewise.
6455 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6457 Do not use Fdelete_overlay in delete_all_overlays
6458 to avoid redundant calls to unchain_overlay.
6459 * buffer.c (drop_overlay): New function.
6460 (delete_all_overlays, Fdelete_overlay): Use it.
6461 * minibuf.c (get_minibuffer): Fix comment.
6463 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
6465 Port to OpenBSD 5.1 amd64.
6466 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
6467 This is needed for OpenBSD, and should be harmless on all BSD systems.
6468 Also, include <sys/sysctl.h>, as it should be available on all
6469 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
6470 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
6471 use p_pid member, not kp_proc.pid.
6473 2012-07-06 Glenn Morris <rgm@gnu.org>
6475 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
6477 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
6479 More xmalloc and related cleanup.
6480 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
6481 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:
6482 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, fns.c:

6486 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:
6487 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
6488 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
6490 Omit needless casts involving void * pointers and allocation.
6491 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
6492 as the former is more robust if P's type is changed.
6493 Prefer xzalloc to xmalloc + memset 0.
6494 Simplify malloc-or-realloc to realloc.
6495 Don't worry about xmalloc returning a null pointer.
6496 Prefer xstrdup to xmalloc + strcpy.
6497 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
6499 * keyboard.c (apply_modifiers_uncached): Prefer local array to
6500 alloca of a constant.
6502 2012-07-05 Eli Zaretskii <eliz@gnu.org>
6504 * xdisp.c (display_line): Fix horizontal pixel coordinates when
6505 hscroll is larger than the line width. Fixes long and futile
6506 looping inside extend_face_to_end_of_line (on a TTY) producing
6507 glyphs that are not needed and thrown away.
6509 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
6511 * marker.c (set_marker_restricted_both): Simplify by using
6514 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
6516 * editfns.c (region_limit): Simplify by using clip_to_bounds.
6518 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
6520 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
6521 not defined (Bug#11768).
6522 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
6523 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
6524 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
6525 followed by gtk_box_set_homogeneous (Bug#11768).
6526 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
6527 (update_theme_scrollbar_width, xg_create_scroll_bar):
6528 Use gtk_scrollbar_new (Bug#11768).
6529 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
6530 (is_box_type): New function (Bug#11768).
6531 (xg_tool_item_stale_p): Call is_box_type.
6532 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
6533 with default display (Bug#11768).
6535 2012-07-05 Eli Zaretskii <eliz@gnu.org>
6537 * xdisp.c (window_hscroll_limited): New function.
6538 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
6539 coordinates when window's hscroll is set to insanely large
6542 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
6544 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
6545 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
6547 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>

6603 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
6605 * fileio.c (time_error_value): Check the right error number.
6606 Problem reported by Troels Nielsen in
6607 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
6609 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
6611 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
6612 This should be fixed in a better way; see Eli Zaretskii in
6613 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
6614 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
6616 * fileio.c (time_error_value): Rename from special_mtime.
6617 The old name's problems were noted by Eli Zaretskii in
6618 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
6620 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
6621 This variable's comment says Emacs needs at least one GDB-visible
6622 symbol of type enum pvec_type, to work around GDB problems.
6623 The symbol's value doesn't matter.
6625 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
6626 that causes compilation to fail on pre-C99 compilers.
6628 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
6630 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
6631 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
6633 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
6635 * buffer.c (init_buffer_once): Fix initialization of
6636 headers for buffer_defaults and buffer_local_symbols.
6637 Reported by Juanma Barranquero <lekktu@gmail.com>.
6639 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
6641 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
6642 * lisp.h (enum pvec_type): Use fewer bits.
6643 (PSEUDOVECTOR_SIZE_BITS): New constant.
6644 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
6645 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
6646 change in pvec_type.
6647 (PSEUDOVECTOR_TYPEP): New macro.
6648 (TYPED_PSEUDOVECTORP): Use it.
6649 * fns.c (internal_equal): Adapt code to extract pvectype.
6650 * emacs.c (gdb_pvec_type): Update type.
6651 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
6652 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
6653 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
6654 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
6655 (sweep_vectors): Use it. Use local var `total_bytes' instead of
6656 abusing vector->header.next.nbytes.
6657 (live_vector_p): Use PVEC_TYPE.
6658 (mark_object): Adapt code to extract pvectype. Use switch.
6660 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
6662 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
6663 Tighten new eassert a bit.
6665 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
6667 Fix compilation with --enable-gcc-warnings and -O1
6669 * doprnt.c (doprnt): Change type of tem to int, initialize
6670 to avoid compiler warning. Add eassert.
6671 * search.c (simple_search): Initialize match_byte to avoid
6672 compiler warning. Add eassert.
6674 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
6676 Avoid weird behavior with large horizontal scrolls.
6677 Without this change, for example, large hscroll values would
6678 mess up Emacs's display on Fedora 15 x86, presumably due to
6679 overflows in int calculations in the display code.
6680 Also, if buffers had long lines, Emacs would freeze.
6681 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
6682 (set_window_hscroll): New function, containing the old guts of
6683 Fset_window_hscroll. Return the clipped value.
6684 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
6685 This avoids the need to check against PTRDIFF_MAX.
6687 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
6689 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
6691 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
6693 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
6695 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
6696 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
6697 since GCC 4.4.6 issues a bogus warning for them.
6699 Fix bugs in file timestamp newness comparisons.
6700 * fileio.c (Ffile_newer_than_file_p):
6701 * lread.c (Fload): Use full timestamp resolution of files,
6702 not just the 1-second resolution, so that files that are only
6703 slightly newer still count as newer.
6704 * fileio.c (Ffile_newer_than_file_p): Don't assume file
6705 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
6707 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
6709 * fileio.c: Improve handling of file time marker. (Bug#11852)
6710 (special_mtime): New function.
6711 (Finsert_file_contents, Fverify_visited_file_modtime):
6712 Use it to set special mtime values consistently.
6714 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
6716 * fileio.c (Finsert_file_contents): Properly handle st_mtime
6717 marker for non-existing file. (Bug#11852)
6719 2012-07-03 Glenn Morris <rgm@gnu.org>
6721 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
6722 and did not make it into globals.h).
6724 2012-07-03 Tom Tromey <tromey@redhat.com>

6760 * xterm.h: Remove EXFUN.
6762 2012-07-03 Glenn Morris <rgm@gnu.org>
6764 * lisp.h (Frandom): Make it visible to C.
6765 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
6766 buffer for invisible buffers. (Bug#1229)
6768 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
6770 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
6771 values which aren't power of 2.
6772 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
6773 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
6776 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
6778 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
6780 * alloc.c (mark_object): Revert part of last patch to use `switch'.
6782 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
6784 * alloc.c (allocate_vector_block): Remove redundant
6785 calls to mallopt if DOUG_LEA_MALLOC is defined.
6786 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
6787 avoid calls to mallopt if zero_vector is returned.
6789 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
6791 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
6792 is enabled, avoid dereferencing NULL current_sblock if
6795 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
6797 Cleanup basic buffer management.
6798 * buffer.h (struct buffer): Change layout to use generic vector
6799 marking code. Fix some comments. Change type of 'clip_changed'
6800 to bitfield. Remove unused #ifndef old.
6801 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
6802 (GET_OVERLAYS_AT): Fix indentation.
6803 (for_each_per_buffer_object_at): New macro.
6804 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)

6807 * alloc.c (allocate_buffer): Adjust to match new layout of
6808 struct buffer. Fix comment.
6809 (mark_overlay): New function.
6810 (mark_buffer): Use it. Use mark_vectorlike to mark normal
6811 Lisp area of struct buffer.
6812 (mark_object): Use it. Adjust marking of misc objects
6813 and related comments.
6815 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
6817 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
6818 wrapper that is not needed because the wrapped code is a no-op (zero
6819 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
6820 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
6822 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
6824 * alloc.c (mark_buffer): Simplify. Remove prototype.
6825 (mark_object): Add comment. Reorganize marking of vector-like
6826 objects. Use CHECK_LIVE for all vector-like objects except buffers
6827 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
6828 Avoid redundant calls to mark_vectorlike for bool vectors.
6830 2012-06-30 Glenn Morris <rgm@gnu.org>
6832 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
6834 * epaths.in (PATH_SITELOADSEARCH): New.
6835 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
6836 This is rather than relying on --enable-locallisppath elements
6837 having "site-lisp" in their names. (Bug#10208#25, 11658)
6839 2012-06-30 Eli Zaretskii <eliz@gnu.org>
6841 * w32proc.c (sys_select): Accept and ignore one more argument.
6843 * w32.c (emacs_gnutls_pull): Call select with one more argument.
6845 * sysselect.h [DOS_NT]: Don't include sys/select.h.
6846 (pselect) [!MS_DOS]: Redirect to sys_select.
6848 * sysdep.c: Don't include dos.h and dosfns.h.
6850 * process.c (sys_select):
6851 * msdos.c (sys_select): Accept one more argument and ignore it.
6853 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
6854 adapt data types and code to that.
6857 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
6858 which clashes with the gnulib function of the same name.
6860 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
6862 * font.c (font_style_to_value, font_style_symbolic)
6863 (font_prop_validate_style): Add type checks for values in
6866 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
6868 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
6871 2012-06-29 Eli Zaretskii <eliz@gnu.org>
6873 * xdisp.c (try_window_id): Undo last change.
6875 * w32.c (getwd): Adjust commentary about startup_dir.
6876 (init_environment): Always call sys_access, even in non-MSVC
6877 builds. Don't chdir to the directory of the Emacs executable.
6878 This undoes code from 1997 which was justified by the need to
6879 "avoid conflicts when removing and renaming directories". But its
6880 downside was that every relative file name was being interpreted
6881 relative to the directory of the Emacs executable, which can never
6882 be TRT. In particular, it broke sys_access when called with
6883 relative file names.
6884 (sys_access): Map GetLastError to errno.
6886 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
6888 * window.h (struct window): Change type of 'fringes_outside_margins'

6892 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
6895 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>

6898 Add QUIT to make the loop interruptible.
6900 2012-06-29 Glenn Morris <rgm@gnu.org>
6902 * charset.c (init_charset): Make lack of etc/charsets fatal.
6904 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
6906 * editfns.c (region_limit): Fix type mismatch.
6908 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
6910 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
6911 undefined. Convert from xassert to eassert.
6912 * nsmenu.m: Convert from xassert to eassert.
6913 * nsterm.m: Likewise.
6915 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
6917 * editfns.c (region_limit): Clip to narrowing (bug#11770).
6919 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
6921 Avoid integer overflow on scroll-left and scroll-right.
6922 * window.c (HSCROLL_MAX): New macro.
6923 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
6924 overflow when requested scroll falls outside ptrdiff_t range.

6928 * window.h (struct window): Change type of 'hscroll',
6929 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
6930 'last_modified' and 'last_overlay_modified' to EMACS_INT.
6931 Adjust users accordingly.
6932 * xdisp.c (try_cursor_movement): Replace type check with eassert.
6933 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
6934 from EMACS_INT to ptrdiff_t.
6935 (make_window): Omit redundant initialization.
6937 2012-06-28 Juanma Barranquero <lekktu@gmail.com>

6941 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
6943 * window.h (struct window): Change type of 'use_time' and
6944 'sequence_number' from Lisp_Object to int.

7010 * alloc.c (allocate_string): Omit intervals initialization.
7011 * alloc.c (make_uninit_multibyte_string): Initialize intervals
7012 as in make_pure_string and make_pure_c_string.

7070 a better opportunity to optimize away calls to strlen when the
7071 function is called with compile-time constant argument.
7072 * image.c (imagemagick_error): Convert to build_string.
7073 * w32proc.c (sys_spawnve): Likewise.

7076 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
7078 Use sprintf return value instead of invoking strlen on result.
7079 In the old days this wasn't portable, since some sprintf
7080 implementations returned char *. But they died out years ago and
7081 Emacs already assumes sprintf returns int.
7082 Similarly for float_to_string.
7083 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

7090 * xfns.c (syms_of_xfns):
7091 Use sprintf or float_to_string result to avoid need to call strlen.
7092 * data.c (Fnumber_to_string):
7093 Use make_unibyte_string, since the string must be ASCII.
7094 * lisp.h, print.c (float_to_string): Now returns int length.
7095 * term.c (produce_glyphless_glyph):
7096 Use sprintf result rather than recomputing it.
7098 Clean out last vestiges of the old HAVE_CONFIG_H stuff.

7131 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

7134 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
7136 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
7137 instead of truncating it to 63 (admittedly a generous limit).
7139 * process.c: Fix spelling and caps in comments.
7141 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
7143 * emacs.c (setpgrp): Remove definition, unused.

7197 * keyboard.c (kbd_buffer_get_event):
7198 * process.c (Faccept_process_output):

7220 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
7221 Privately reported by Herbert J. Skuhra.
7222 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
7224 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,

7267 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
7269 Support higher-resolution time stamps (Bug#9000).
7270 The time stamps are only nanosecond-resolution at the C level,
7271 since that's the best that any real-world system supports now.
7272 But they are picosecond-resolution at the Lisp level, as that's
7273 easy, and leaves room for future OS improvements.
7275 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
7278 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
7279 Don't get current time unless it's needed.
7281 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
7282 now provides it if it's absent.
7283 (start_atimer): Port to higher-res time stamps.
7284 Check for time stamp overflow. Don't get current time more
7285 often than is needed.
7287 * buffer.h (struct buffer): Buffer modtime now has high resolution.
7288 Include systime.h, not time.h.
7289 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
7291 * dired.c: Include stat-time.h.
7292 (Ffile-attributes): File times now have higher resolution.
7294 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
7295 (struct image): Timestamp now has higher resolution.
7297 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
7298 has at least microseconds now. All uses removed.
7299 (update_frame, update_single_window, update_window, update_frame_1)
7300 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
7301 (duration_to_sec_usec): Remove; no longer needed.
7303 * editfns.c (time_overflow): Now extern.
7304 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
7305 (float-time, Fformat_time_string, Fcurrent_time_string)
7306 (Fcurrent_time_zone): Accept and generate higher-resolution
7308 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
7309 (decode_time_components, lisp_seconds_argument): New functions.
7310 (make_time): Now static.
7311 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
7312 Report an error if the time is invalid, rather than having the caller
7315 * fileio.c: Include <stat-time.h>
7316 (Fcopy_file): Copy higher-resolution time stamps.
7317 Prefer to set the time stamp via a file descriptor if that works.
7318 (Fset_file_times, Finsert_file_contents, Fwrite_region)
7319 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
7320 (Fvisited_file_modtime, Fset_visited_file_modtime):
7321 Support higher-resolution time stamps.
7323 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
7325 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
7327 * image.c (prepare_image_for_display, clear_image_cache)
7328 (lookup_image): Port to higer-resolution time stamps.
7330 * keyboard.c (start_polling, bind_polling_period):
7331 Check for time stamp overflow.
7332 (read_char, kbd_buffer_get_event, timer_start_idle)
7333 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
7334 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
7335 Port to higher-resolution time stamps. Do not assume time_t is signed.
7336 (decode_timer): New function. Timers are now vectors of length 9,
7337 not 8, to accommodate the picosecond component.
7338 (timer_check_2): Use it.
7340 * nsterm.m (select_timeout, timeval_subtract): Remove.
7341 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
7342 as they're a bit more accurate and handle overflow better.
7343 (ns_select): Change prototype to be compatible with pselect.
7344 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
7345 * nsterm.h (ns_select): Adjust prototype.
7347 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
7348 us-resolution time stamps.
7349 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
7351 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
7353 * lisp.h (time_overflow): New decl.
7354 (wait_reading_process_output): First arg is now intmax_t, not int,
7355 to accommodate larger waits.
7357 * process.h (struct Lisp_Process.read_output_delay):
7358 Now counts nanoseconds, not microseconds.
7359 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
7361 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
7362 (wait_reading_process_output):
7363 Port to ns-resolution time stamps.
7364 (Faccept_process_output, wait_reading_process_output):
7365 Check for time stamp overflow. Do not assume time_t is signed.
7366 (select_wrapper): Remove; we now use pselect.
7367 (Fprocess_attributes): Now generates ns-resolution time stamps.
7369 * sysdep.c: Include utimens.h. Don't include utime.h
7370 or worry about struct utimbuf; gnulib does that for us now.
7371 (gettimeofday): Remove; gnulib provides a substitute.
7372 (make_timeval): New function.
7373 (set_file_times): Now sets ns-resolution time stamps.
7374 New arg FD; all uses changed.
7375 (time_from_jiffies, ltime_from_jiffies, get_up_time)
7376 (system_process_attributes):
7377 Now returns ns-resolution time stamp. All uses changed.
7378 Check for time stamp overflow.
7380 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
7381 provides a substitute now.
7383 * systime.h: Include timespec.h rather than sys/time.h and time.h,
7384 since it guarantees struct timespec.
7385 (EMACS_TIME): Now struct timespec, so that we can support
7386 ns-resolution time stamps.
7387 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
7388 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
7389 (EMACS_USECS): Remove.
7390 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
7391 so multiply the arg by 1000 before storing it.
7392 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
7394 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
7395 Port to ns-resolution time stamps.
7396 (EMACS_TIME_NEG_P): Remove; replaced by....
7397 (EMACS_TIME_SIGN): New macro.
7398 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
7399 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
7400 (set_file_times, make_time, lisp_time_argument): Adjust signature.
7401 (make_timeval, make_lisp_time, decode_time_components): New decls.
7402 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
7403 that it mishandled time_t overflow. You can't compare by subtracting!
7404 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
7405 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
7407 * term.c: Include <sys/time.h>.
7408 (timeval_to_Time): New function, for proper overflow wraparound.
7409 (term_mouse_position, term_mouse_click): Use it.
7411 * undo.c (record_first_change): Support higher-resolution time stamps
7413 (Fprimitive_undo): Use them when restoring time stamps.
7415 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
7416 (w32_get_internal_run_time):
7417 Port to higher-resolution Emacs time stamps.
7418 (ltime): Now accepts single 64-bit integer, as that's more convenient
7421 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
7423 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
7424 for compatibility with pselect. Support ns-resolution time stamps.
7426 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
7428 * xselect.c (wait_for_property_change, x_get_foreign_selection):
7429 Check for time stamp overflow, and support ns-resolution time stamps.
7431 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
7432 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
7433 (timeval_subtract): Remove; no longer needed.
7434 (XTflash, XTring_bell, x_wait_for_event):
7435 Port to ns-resolution time stamps. Don't assume time_t is signed.
7437 2012-06-22 Chong Yidong <cyd@gnu.org>
7439 * xdisp.c (x_consider_frame_title): Revert last change.
7441 2012-06-22 Eli Zaretskii <eliz@gnu.org>
7443 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
7444 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
7445 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
7446 staticidx goes up to 1597 out of 1600 = 0x640.)
7448 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
7450 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
7451 Otherwise, the umask might be mistakenly 0 while handling input signals.
7453 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
7455 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

7461 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
7462 access to `contents' member of Lisp_Vector objects with AREF and ASET
7465 2012-06-19 Chong Yidong <cyd@gnu.org>
7467 * frame.c (delete_frame): When selecting a frame on a different
7468 text terminal, do not alter the terminal's top-frame.

7471 frame's selected window and its terminal's top-frame.
7472 (unwind_format_mode_line): Restore them.
7473 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
7475 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
7476 since tty frames can be explicitly named.
7477 (prepare_menu_bars): Likewise.
7479 * term.c (Ftty_top_frame): New function.
7481 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
7483 Port byte-code-meter to modern targets.
7484 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
7485 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
7486 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
7487 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
7488 (METER_1, METER_2): Simplify.
7490 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
7492 * data.c (Fdefalias): Return `symbol' (bug#11686).
7494 2012-06-18 Martin Rudalics <rudalics@gmx.at>
7496 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
7497 gets killed during executing of this function (Bug#11665).
7498 Try to always return Qt when the buffer has been actually killed.
7499 (Vkill_buffer_query_functions): In doc-string say that functions
7500 run by this hook should not change the current buffer.
7502 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
7504 Fix recently-introduced process.c problems found by static checking.
7505 * process.c (write_queue_push, write_queue_pop, send_process):
7506 Use ptrdiff_t, not int or EMACS_INT, for buffer lengths and offsets.
7507 (write_queue_pop): Fix pointer signedness problem.
7508 (send_process): Remove unused local.
7510 2012-06-17 Chong Yidong <cyd@gnu.org>

7513 frames that are not on top.
7515 2012-06-17 Troels Nielsen <bn.troels@gmail.com>
7517 * process.c (make_process): Initialize write_queue.

7522 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
7524 * lisp.h (eassert): Assume C89 or later.
7525 This removes the need for CHECK.
7526 (CHECK): Remove. Its comments about always evaluating its
7527 argument were confusing, as 'eassert' typically does not evaluate
7530 * coding.c (produce_chars): Use ptrdiff_t, not int.
7532 * xterm.c (x_draw_underwave): Check for integer overflow.
7533 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.
7535 2012-06-17 Jan Djärv <jan.h.d@swipnet.se>
7537 * nsterm.m (x_free_frame_resources): Move xfree so freed memory isn't

7624 2012-06-16 Eli Zaretskii <eliz@gnu.org>
7626 * xdisp.c (set_cursor_from_row): Don't dereference glyphs_end.
7627 If all the glyphs of the glyph row came from strings, and we have no
7628 cursor positioning clues, put the cursor on the first glyph of the

7656 (LISP_INT1_TAG, enum Lisp_Type, XINT, XUINT, make_number):
7657 Simplify under the assumption that USE_2_TAGS_FOR_INTS is defined.
7658 (INTTYPEBITS): New macro, for clarity.
7659 (INTMASK, MOST_POSITIVE_FIXNUM): Use it.
7660 (LISP_INT1_TAG, LISP_STRING_TAG, LISP_INT_TAG_P):

7685 * frame.c (delete_frame): Remove outdated comment.
7686 * w32fns.c (Fw32_register_hot_key): Use XLI instead of checking
7687 USE_LISP_UNION_TYPE.

7700 Remove define/undef of HAVE_SYSV_SIGPAUSE (not used since 2010-05-04).
7702 * s/gnu.h (POSIX_SIGNALS): Remove (not used since 2010-05-04).
7704 2012-06-13 Paul Eggert <eggert@cs.ucla.edu>
7706 USE_LISP_UNION_TYPE + USE_LSB_TAG cleanup (Bug#11604)
7707 * alloc.c (make_number) [!defined make_number]:
7708 Remove, as lisp.h always defines this now.
7709 (mark_maybe_pointer): Simplify since USE_LSB_TAG is always defined now.
7710 (roundup_size): Verify that it is a power of 2.
7711 * data.c (Fmake_variable_buffer_local, Fmake_local_variable):

7713 * lisp.h (USE_LSB_TAG): Allow the builder to compile with
7714 -DUSE_LSB_TAG=0, to override the automatically-selected default.
7715 USE_LSB_TAG now is always defined to be either 0 or 1.
7717 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
7718 code works fine either way, and efficiency is not a concern here,
7719 as the union type is for debugging, not for production.
7720 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
7721 Use an inline function on all platforms when using the union type,
7722 since this is simpler and 'static inline' can be used portably
7724 (LISP_INITIALLY_ZERO): New macro.
7725 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
7726 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.

7866 * doprnt.c (doprnt): Truncate multibyte char correctly.
7867 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
7868 would mishandle a string argument "Xc" if X was a multibyte
7869 character of length 2: it would truncate after X's first byte
7870 rather than including all of X.
7872 2012-06-06 Chong Yidong <cyd@gnu.org>
7874 * buffer.c (word_wrap): Doc fix.

7927 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
7929 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
7932 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
7934 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
7936 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
7938 For a 'struct window', replace some Lisp_Object fields to
7939 bitfields where appropriate, remove unused fields.
7940 * window.h (struct window): Remove unused 'last_mark_x' and
7941 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
7942 change its type from Lisp_Object to bitfield.
7943 Change type of 'force_start', 'optional_new_start',
7944 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
7945 fields from Lisp_Object to bitfield. Adjust users accordingly.
7947 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
7949 Pacify gcc -Wdouble-precision when using Xaw.

7951 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
7952 Use 'float' consistently, rather than 'float' in most places
7953 and 'double' in a couple of places.
7955 2012-05-31 Eli Zaretskii <eliz@gnu.org>
7957 * xdisp.c (handle_stop): Detect whether we have overlay strings
7958 loaded by testing it->current.overlay_string_index to be
7959 non-negative, instead of checking whether n_overlay_strings is
7960 positive. (Bug#11587)
7962 2012-05-31 Chong Yidong <cyd@gnu.org>
7964 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

7970 * search.c (search_buffer): Remove calls to
7971 r_alloc_inhibit_buffer_relocation, as it is now called by
7972 maybe_unify_char, which was the cause of relocation of buffer text
7975 2012-05-31 Eli Zaretskii <eliz@gnu.org>
7977 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
7978 for the duration of call to load_charset, to avoid problems with
7979 callers of maybe_unify_char that access buffer text through C
7982 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
7983 decrement the inhibition flag, instead of just setting or
7986 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
7988 Remove obsolete '#define static' cruft.
7989 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
7990 This #undef was "temporary" in 2000; it is no longer needed
7991 now that '#define static' has gone away.
7992 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
7993 (gray_bitmap_bits): Remove; no longer needed.
7994 All uses replaced with definiens.
7995 * xterm.c: Include "bitmaps/gray.xbm".
7997 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
7999 Clean up __executable_start, monstartup when --enable-profiling.
8000 The following changes affect the code only when profiling.
8001 * dispnew.c (__executable_start): Rename from safe_bcopy.
8002 Define only on platforms that need it.
8003 * emacs.c: Include <sys/gmon.h> when profiling.
8004 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.

8006 (safe_bcopy): Remove decl; no longer has that name.
8007 (main): Coalesce #if into single bit of code, for simplicity.

8037 Do not create empty overlays with the evaporate property (Bug#9642).
8038 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
8039 Bug#9642, but explicitly check that the buffer the overlay would
8040 be moved to is live and rearrange lines to make sure that errors
8041 will not put the overlay in an inconsistent state.
8042 (Fdelete_overlay): Cosmetics.
8044 2012-05-28 Eli Zaretskii <eliz@gnu.org>
8046 * w32term.c (my_bring_window_to_top): New function.

8058 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
8060 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
8061 This avoids undefined behavior that might cause the eassert
8062 to not catch an out-of-range value.
8064 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
8066 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

8080 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
8081 Only r_alloc_inhibit_buffer_relocation needed to be added;
8082 the others were already declared.
8084 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
8085 before checking whether it's out of range. Put the check inside
8087 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
8089 2012-05-27 Ken Brown <kbrown@cornell.edu>

8097 defined on ralloc.c.
8099 * buffer.c [REL_ALLOC]: Remove prototypes of

8105 * search.c (search_buffer): Use it to inhibit relocation of buffer
8106 text while re_search_2 is doing its job, because re_search_2 is
8107 passed C pointers to buffer text. (Bug#11519)
8109 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
8112 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator

8117 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
8120 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
8122 Fix coding-related core dumps with gcc -ftrapv.
8123 The code was computing A - B, where A and B are pointers, and B is
8124 random garbage. This can lead to core dumps on platforms that
8125 have special pointer registers, and it also leads to core dumps on
8126 x86-64 when compiled with gcc -ftrapv. The fix is to compute
8127 A - B only when B is initialized properly.
8128 * coding.c (coding_set_source, coding_set_destination): Return void.
8129 (coding_change_source, coding_change_destinations): New functions,
8130 with the old behaviors of coding_set_source and coding_set_destination.

8135 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
8137 2012-05-26 Eli Zaretskii <eliz@gnu.org>
8139 Extend mouse support on W32 text-mode console.
8140 * xdisp.c (draw_row_with_mouse_face):
8141 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
8143 * w32console.c: Include window.h.
8144 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
8146 (initialize_w32_display): Initialize mouse-highlight data.
8148 * w32inevt.c: Include termchar.h and window.h.
8149 (do_mouse_event): Support mouse-autoselect-window. When the mouse
8150 moves, call note_mouse_highlight. If help_echo changed, call
8151 gen_help_event to produce help-echo message in the echo area.
8152 Call clear_mouse_face if mouse_face_hidden is set in the mouse
8155 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
8157 * lread.c (read1): Simplify slightly to avoid an overflow warning
8158 with GCC 4.7.0 on x86-64.
8160 2012-05-26 Eli Zaretskii <eliz@gnu.org>

8178 (allocate_pseudovector):
8179 Use int, not EMACS_INT, where int is wide enough.

8202 (validate_region): Omit unnecessary test for b <= e,
8203 since that's guaranteed by the previous test.
8204 (adjust_overlays_for_delete): Avoid pos + length overflow.
8205 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
8206 (report_overlay_modification):
8207 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
8208 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):

8212 * buffer.h: Adjust decls to match defn changes elsewhere.

8217 not int, to avoid needless 32-bit limit on 64-bit hosts.
8218 (exec_byte_code): Use tighter memory-full test, one that checks
8219 for alloca overflow. Don't compute the address of the object just
8220 before an array, as that's not portable. Use EMACS_INT, not
8221 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
8222 * callint.c (Fcall_interactively):
8223 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

8234 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
8235 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8236 (casify_object): Avoid integer overflow when overallocating buffer.
8237 * casetab.c (set_identity, shuffle): Prefer int to unsigned when

8240 * category.h (CATEGORYP): Don't assume arg is nonnegative.
8241 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
8242 integers are now checked earlier. All uses replaced with XINT.
8244 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8245 For CCL_MapSingle, check that content and value are in int range.

8247 Check that Vcode_version_map_vector is a vector.
8248 (resolve_symbol_ccl_program): Check that vector header is in range.
8249 Always copy the vector, so that we can check its contents reliably
8250 now rather than having to recheck each instruction as it's being
8251 executed. Check that vector words fit in 'int'.
8252 (ccl_get_compiled_code, Fregister_ccl_program)
8253 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
8254 program indexes, to avoid needless 32-bit limit on 64-bit hosts.

8256 contents are in range.
8257 (Fccl_execute_on_string): Check that status is in range.
8258 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
8259 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
8260 Accept and return EMACS_INT, not int, because callers can pass values

8267 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

8269 avoid mishandling large integers.

8281 Don't assume unsigned int fits into fixnum, or that fixnum fits
8282 into unsigned int. Don't require max_code to be a valid fixnum;
8283 that's not true for gb10830 4-byte on a 32-bit host. Allow
8284 invalid_code to be a cons, for the same reason. Require code_offset
8285 to be a character. Avoid int overflow if max_char is close
8287 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
8288 this is intended anyway and avoids some undefined behavior.
8289 (load_charset_map): Pass unsigned, not int, as 2nd arg of
8290 INDEX_TO_CODE_POINT, as that's what it expects.
8291 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
8292 * charset.h (DECODE_CHAR): Return int, not unsigned;
8293 this is what was intended anyway, and it avoids undefined behavior.
8294 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
8295 integer-overflow issues.
8296 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
8297 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
8298 where the argument is EMACS_INT, and this behavior is not intended.
8299 * chartab.c (Fmake_char_table, Fset_char_table_range)
8300 (uniprop_get_decoder, uniprop_get_encoder):
8301 Don't assume fixnum fits in int.
8302 * cmds.c (move_point): New function, that does the gist of
8303 Fforward_char and Fbackward_char, but does so while checking
8304 for integer overflow more accurately.
8305 (Fforward_char, Fbackward_char): Use it.
8306 (Fforward_line, Fend_of_line, internal_self_insert)
8307 (internal_self_insert):
8308 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

8910 (last_escape_glyph_face_id, last_glyphless_glyph_face_id):
8911 (handle_tool_bar_click):
8912 Use int, not unsigned, since we prefer signed and the signedness
8913 doesn't matter here.

8967 2012-05-25 Glenn Morris <rgm@gnu.org>
8969 * lisp.mk (lisp): Update for more files being compiled now.
8971 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>
8973 * lread.c: Remove `read_pure' which makes no difference.
8974 (read_pure): Remove var.
8975 (unreadpure): Remove function.
8976 (readevalloop): Don't call read_list with -1 flag.
8977 (read1, read_vector): Don't test read_pure any more.
8978 (read_list): Simplify.

8991 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
8994 This directory predates autoconf and is no longer needed nowadays.
8995 Move its few remaining bits of functionality to where they're needed.
8996 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:

9005 (EMACS_UINT): Define unconditionally now.
9006 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
9007 (BITS_PER_EMACS_INT): New constants, replacing
9008 what used to be in config.h, but not useful in #if.
9009 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
9010 define them any more.
9011 (VAL_MAX): New macro.
9013 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
9014 BITS_PER_EMACS_INT, in #if.
9015 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
9016 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
9017 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
9018 * s/ms-w32.h (DATA_START):
9019 Move here from removed file m/intel386.h.
9020 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
9021 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
9023 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
9025 Assume C89 or later.

9035 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
9036 * xterm.c (input_signal_count): Assume volatile works.
9038 2012-05-21 Ken Brown <kbrown@cornell.edu>
9040 * xgselect.c (xg_select): Fix first argument in call to 'select'
9043 2012-05-20 Ken Brown <kbrown@cornell.edu>
9045 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
9046 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
9048 2012-05-19 Ken Brown <kbrown@cornell.edu>
9050 * xfns.c (x_in_use): Remove `static' qualifier.
9051 * xterm.h (x_in_use): Declare.
9052 * xgselect.c: Include xterm.h.
9053 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
9054 and `display_arg' (bug#9754).
9056 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
9058 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
9060 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
9061 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
9063 2012-05-18 Eli Zaretskii <eliz@gnu.org>
9065 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.

9068 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
9070 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
9071 reference to image_cache->refcount.
9072 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
9074 2012-05-17 Juri Linkov <juri@jurta.org>
9076 * search.c (Fword_search_regexp, Fword_search_backward)
9077 (Fword_search_forward, Fword_search_backward_lax)
9078 (Fword_search_forward_lax): Move functions to isearch.el
9079 (bug#10145, bug#11381).
9081 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
9083 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
9085 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
9087 * lread.c (init_obarray): Declare Qt and Qnil as special.
9089 2012-05-14 Glenn Morris <rgm@gnu.org>
9091 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
9092 Put "libexec" before "bin", for the sake of init_callproc_1.
9094 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
9096 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
9098 * unexaix.c: Port to more-recent AIX compilers.
9099 (report_error, report_error_1, make_hdr, copy_sym)
9100 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
9101 Make arguments const char *, not char *, to avoid violations of C
9102 standard and to fix some AIX warnings reported by Gilles Pion.
9104 2012-05-14 Eli Zaretskii <eliz@gnu.org>
9106 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
9107 already have overlays loaded.
9108 (handle_single_display_spec): Before returning without displaying
9109 fringe bitmap, synchronize the bidi iterator with the main display
9110 iterator, by calling iterate_out_of_display_property.
9111 (iterate_out_of_display_property): Detect buffer iteration by
9112 testing that it->string is a Lisp string.
9113 (get_next_display_element): When the current object is exhausted,
9114 and there's something on it->stack, call set_iterator_to_next to
9115 proceed with what's on the stack, instead of returning zero.
9116 (set_iterator_to_next): If called at the end of a Lisp string,
9117 proceed to consider_string_end without incrementing string
9118 position. Don't increment display vector index past the end of
9119 the display vector. (Bug#11417)
9120 (pos_visible_p): Don't report a position visible when move_it_to
9121 stopped at the last line of window, which happens to be scanned
9122 backwards by the bidi iteration. (Bug#11464)
9124 2012-05-14 Eli Zaretskii <eliz@gnu.org>
9126 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
9127 and right-margin display specs even if the spec is invalid or we
9128 are on a TTY, and thus unable to display on the fringes.
9129 That's because the text with the property will not be displayed anyway,
9130 so we need to signal to the caller that this is a "replacing"
9131 display spec. This fixes display when the spec is invalid or we
9134 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
9136 * unexaix.c (make_hdr): Fix typo in prototype.
9137 This bug broke the build on AIX. Problem reported by Gilles Pion.
9139 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
9141 * keyboard.c (kbd_buffer_get_event): Read special events also in
9142 batch mode. (Bug#11415)
9144 2012-05-12 Glenn Morris <rgm@gnu.org>
9146 * ns.mk: Update for ns_appbindir no longer having trailing "/".
9148 2012-05-12 Eli Zaretskii <eliz@gnu.org>
9150 * lisp.mk (lisp): Add newcomment.elc.
9152 2012-05-12 Glenn Morris <rgm@gnu.org>
9154 * Makefile.in (MKDIR_P): New, set by configure.
9155 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
9157 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
9159 Remove unused function hourglass_started.
9160 * dispextern.h (hourglass_started):
9161 * w32fns.c (hourglass_started):
9162 * xdisp.c (hourglass_started): Remove.
9164 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
9166 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
9167 Update dependencies.
9169 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
9171 * xgselect.c (xg_select): Put maxfds+1 into a var.
9172 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
9174 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
9176 2012-05-10 Dave Abrahams <dave@boostpro.com>
9178 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
9179 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
9181 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
9183 * dbusbind.c (xd_registered_buses): New internal Lisp object.
9184 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
9185 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
9186 Initialize xd_registered_buses.
9188 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
9190 Untag more efficiently if USE_LSB_TAG.
9191 This is based on a proposal by YAMAMOTO Mitsuharu in
9192 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
9193 For an admittedly artificial (nth 8000 longlist) benchmark on
9194 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
9195 Emacs's overall text size by 1%.
9196 * lisp.h (XUNTAG): New macro.
9197 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
9198 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
9199 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
9200 * eval.c (Fautoload):
9201 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
9202 * frame.h (XFRAME): Use XUNTAG.
9204 Port recent dbusbind.c changes to 32-bit --with-wide-int.
9205 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
9206 Remove unportable assumptions about print widths of types like
9208 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
9209 intptr_t when converting between pointer and integer, to avoid GCC
9210 warnings about wrong width.
9212 2012-05-09 Eli Zaretskii <eliz@gnu.org>
9214 * w32proc.c (new_child): Force Windows to reserve only 64KB of
9215 stack for each reader_thread, instead of defaulting to 8MB
9216 determined by the linker. This avoids failures in creating
9217 subprocesses on Windows 7, see the discussion in this thread:
9218 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
9220 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
9222 Fix up display of the *Minibuf-0* buffer in the mini window.
9223 * keyboard.c (read_char): Don't clear the echo area if there's no
9225 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
9226 contents of *Minibuf-0*) if there's no message displayed in its stead.
9228 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
9230 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
9233 2012-05-06 Chong Yidong <cyd@gnu.org>
9235 * lisp.mk (lisp): Update.
9237 2012-05-05 Jim Meyering <meyering@redhat.com>
9239 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
9241 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
9243 * data.c (PUT_ERROR): New macro.
9244 (syms_of_data): Use it. Add new error type `user-error'.
9245 * undo.c (user_error): New function.
9246 (Fprimitive_undo): Use it.
9247 * print.c (print_error_message): Adjust print style for `user-error'.
9248 * keyboard.c (user_error): New function.
9249 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
9251 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
9253 Do not limit current-time-string to years 1000..9999.
9254 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
9255 (Fcurrent_time_string): Support any year that is supported by the
9256 underlying localtime representation. Don't use asctime, as it
9257 has undefined behavior for years outside the range -999..9999.
9259 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
9261 Fix race conditions involving setenv, gmtime, localtime, asctime.
9262 Without this fix, interrupts could mess up code that uses these
9263 nonreentrant functions, since setting TZ invalidates existing
9264 tm_zone or tzname values, and since most of these functions return
9265 pointers to static storage.
9266 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
9267 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
9268 Grow the critical sections to include not just invoking
9269 localtime/gmtime, but also accessing these functions' results
9270 including their tm_zone values if any, and any related TZ setting.
9271 (format_time_string): Last arg is now struct tm *, not struct tm **,
9272 so that the struct tm is saved in the critical section.
9273 All callers changed. Simplify allocation of initial buffer, partly
9274 motivated by the fact that memory allocation needs to be outside
9275 the critical section.
9277 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
9279 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
9280 with RESET_INTERVAL.
9282 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
9283 Remove duplicated buffer name initialization.
9285 2012-05-02 Jim Meyering <jim@meyering.net>
9287 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
9289 * xfns.c (x_window): Use xstrdup (Bug#11375).
9291 2012-05-02 Eli Zaretskii <eliz@gnu.org>
9293 * xdisp.c (pos_visible_p): If already at a newline from the
9294 display string before the 'while' loop, don't walk back the glyphs
9295 from it3.glyph_row. Solves assertion violation when the display
9296 string begins with a newline (egg.el). (Bug#11367)
9298 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
9300 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
9303 2012-05-01 Glenn Morris <rgm@gnu.org>
9305 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
9306 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
9307 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
9308 All were removed before 23.1.
9310 * dispnew.c: Remove HAVE_LIBNCURSES test;
9311 it is always true on relevant platforms.
9313 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
9314 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
9316 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
9318 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
9320 * .gdbinit (xpr): Remove checks for no longer existing misc types.
9321 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
9324 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
9326 Do not avoid creating empty evaporating overlays (Bug#9642).
9327 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
9328 That is, do not delete an evaporating overlay if it becomes
9329 empty after its bounds are adjusted to fit within its buffer.
9330 This fix caused other problems, and I'm reverting it until we get
9331 to the bottom of them.
9333 2012-04-27 Chong Yidong <cyd@gnu.org>
9335 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
9337 2012-04-27 Eli Zaretskii <eliz@gnu.org>

9394 Do not create empty overlays with the evaporate property (Bug#9642).
9395 * buffer.c (Fmove_overlay): Delete an evaporating overlay
9396 if it becomes empty after its bounds are adjusted to fit within
9397 its buffer. Without this fix, in a nonempty buffer (let ((o
9398 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
9399 yields an empty overlay that has the evaporate property, which is
9400 not supposed to happen.

9540 (print_object): Check for cycles even when print-circle is nil and
9541 print-gensym is t, but only check print_depth if print-circle is nil.
9543 2012-04-20 Chong Yidong <cyd@gnu.org>
9545 * process.c (wait_reading_process_output): If EIO occurs on a pty,
9546 set the status to "failed" and ensure that sentinel is run.

9601 New extern decls, to avoid calling undeclared functions.
9602 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
9603 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
9604 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.

9606 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
9607 Remove one incorrect comment and fix another.

9626 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
9628 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

9674 2012-04-11 Daniel Colascione <dancol@dancol.org>
9676 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
9677 against is gone. It's better to use vfork now so that when Cygwin
9678 gains a new, working vfork, we use it automatically (bug#10398).
9680 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

9735 2012-04-09 Eli Zaretskii <eliz@gnu.org>
9737 * xdisp.c (set_cursor_from_row): If the display string appears in
9738 the buffer at position that is closer to point than the position
9739 after the display string, display the cursor on the first glyph of
9740 the display string. Fixes cursor display when a 'display' text
9741 property immediately follows invisible text. (Bug#11094)
9743 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
9745 composite.c: use 'double' consistently
9746 * composite.c (get_composition_id): Use 'double' consistently
9747 instead of converting 'float' to 'double' and vice versa; this is
9748 easier to understand and avoids a GCC warning.
9750 2012-04-09 Glenn Morris <rgm@gnu.org>
9752 * Makefile.in: Generate leim-list with bootstrap-emacs, in
9753 preparation for dumping it with emacs. (Bug#4789)

9790 * makefile.w32-in (OBJ2): Add xml.$(O).
9791 (GLOBAL_SOURCES): Add xml.c.
9792 ($(BLD)/xml.$(O)): New dependency list.
9794 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
9795 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
9796 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
9797 [!WINDOWSNT]: New macros.
9798 (init_libxml2_functions, libxml2_loaded_p): New functions.
9799 (parse_region): Call fn_xmlCheckVersion instead of using the macro
9800 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
9801 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
9802 Calls xmlCleanupParser only if libxml2 was loaded (or statically
9804 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
9805 Call init_libxml2_functions before calling libxml2 functions.
9806 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
9808 * emacs.c: Don't include libxml/parser.h.
9809 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
9810 xmlCleanupParser directly.
9812 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
9814 2012-04-07 Eli Zaretskii <eliz@gnu.org>
9816 * indent.c (Fvertical_motion): If there is a display string at
9817 point, use it.vpos to compute how many lines to backtrack after
9818 move_it_to point. (Bug#11133)
9820 2012-04-06 Eli Zaretskii <eliz@gnu.org>
9822 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
9823 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
9824 about subtle differences between FETCH_CHAR* and STRING_CHAR*
9825 macros related to unification of CJK characters. For the details,
9826 see the discussion following the message here:
9827 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
9829 2012-04-04 Chong Yidong <cyd@gnu.org>
9831 * keyboard.c (Vdelayed_warnings_list): Doc fix.
9833 2012-04-01 Eli Zaretskii <eliz@gnu.org>
9835 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
9836 instead of alloca. (Bug#11138)
9838 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>

9843 2012-03-31 Eli Zaretskii <eliz@gnu.org>
9845 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
9846 position we get to after a call to move_it_to fails the
9847 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
9848 only if we wind up in a string from display property. (Bug#11063)
9850 * window.c (Fdelete_other_windows_internal): Invalidate the row
9851 and column information about mouse highlight, so that redisplay
9852 restores it after reallocating the glyph matrices. (Bug#7464)
9854 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
9855 string comes from a `display' text property, use the buffer
9856 position of that property as if we actually saw that position in
9858 (move_it_by_lines): Remove the assertion that
9859 "it->current_x == 0 && it->hpos == 0" which can be legitimately
9860 violated when there's a before-string at the beginning of a line.
9863 2012-03-30 Eli Zaretskii <eliz@gnu.org>
9865 * xdisp.c (append_space_for_newline): If the default face was
9866 remapped, use the remapped face for the appended newline.
9867 (extend_face_to_end_of_line): Use the remapped default face for
9868 extending the face to the end of the line.
9869 (display_line): Call extend_face_to_end_of_line when the default
9870 face was remapped. (Bug#11068)
9872 2012-03-29 Eli Zaretskii <eliz@gnu.org>
9874 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
9876 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
9878 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
9880 2012-03-27 Glenn Morris <rgm@gnu.org>
9882 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
9885 2012-03-26 Kenichi Handa <handa@m17n.org>
9887 * dispextern.h (struct glyph): Fix previous change. Change the
9888 bit length of glyphless.ch to 25 (Bug#11082).
9890 2012-03-26 Chong Yidong <cyd@gnu.org>
9892 * keyboard.c (Vselection_inhibit_update_commands): New variable.
9893 (command_loop_1): Use it; inhibit selection update for
9894 handle-select-window too (Bug#8996).
9896 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
9898 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
9900 2012-03-25 Kenichi Handa <handa@m17n.org>
9902 * dispextern.h (struct glyph): Change the bit length of
9903 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
9905 2012-03-24 Eli Zaretskii <eliz@gnu.org>
9907 * s/ms-w32.h (tzname): Include time.h before redirecting to
9908 _tzname. Fixes the MSVC build. (Bug#9960)
9910 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
9912 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
9915 * xterm.c (XTread_socket): Only modify handling_signal if
9916 !SYNC_INPUT. (Bug#11080)
9918 2012-03-23 Eli Zaretskii <eliz@gnu.org>
9920 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
9921 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
9922 when fetching a multibyte character consumes more bytes than
9923 CHAR_BYTES returns, due to unification of CJK characters in
9924 string_char. (Bug#11073)
9926 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
9928 * process.c (wait_reading_process_output): Handle pty disconnect
9929 by refraining from sending oneself a SIGCHLD (bug#10933).
9931 2012-03-22 Chong Yidong <cyd@gnu.org>

9935 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
9936 Mark string as coming from a prefix property.
9937 (handle_face_prop): Use default face for prefix strings (Bug#4281).
9938 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
9940 2012-03-21 Chong Yidong <cyd@gnu.org>
9942 * xfaces.c (Vface_remapping_alist): Doc fix.
9944 2012-03-20 Eli Zaretskii <eliz@gnu.org>
9946 * w32proc.c (Fw32_set_console_codepage)
9947 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
9950 2012-03-20 Chong Yidong <cyd@gnu.org>
9952 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
9953 to reflect default non-nil value of redisplay-dont-pause.
9955 2012-03-19 Kenichi Handa <handa@m17n.org>
9957 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
9958 it fit in a valid range (Bug#11003).
9960 2012-03-18 Eli Zaretskii <eliz@gnu.org>
9962 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
9963 that is not from display property, accept the row as a "cursor
9964 row" if one of the string's character has a non-nil `cursor'
9965 property. Fixes cursor positioning when there are newlines in
9966 overlay strings, e.g. in icomplete.el. (Bug#11035)
9968 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
9970 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
9972 2012-03-12 Chong Yidong <cyd@gnu.org>
9974 * eval.c (inhibit_lisp_code): Rename from
9975 inhibit_window_configuration_change_hook; move from window.c.
9977 * xfns.c (unwind_create_frame_1, Fx_create_frame):
9978 * window.c (run_window_configuration_change_hook)
9979 (syms_of_window): Callers changed.
9981 2012-03-11 Chong Yidong <cyd@gnu.org>

9990 is visible (Bug#10955).
9992 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
9994 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).

9998 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
9999 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
10002 2012-03-03 Glenn Morris <rgm@gnu.org>
10004 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
10006 2012-03-02 Eli Zaretskii <eliz@gnu.org>
10008 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
10009 position past the first glyph_row that ends at ZV. (Bug#10902)
10010 (redisplay_window, next_element_from_string): Fix typos in
10012 (redisplay_window): Pass to move_it_vertically the margin in
10013 pixels, not in screen lines.
10015 2012-03-02 Glenn Morris <rgm@gnu.org>
10017 * buffer.c (buffer-list-update-hook): Doc fix.
10019 2012-02-29 Eli Zaretskii <eliz@gnu.org>
10021 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
10022 push_it before setting up the iterator for the first overlay
10023 string, even if we have an empty string loaded.
10024 (next_overlay_string): If there's an empty string on the iterator
10025 stack, pop the stack. (Bug#10903)
10027 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
10029 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
10030 Suggested by Stefan Monnier in
10031 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
10032 * alloc.c (widen_to_Lisp_Object): New static function.
10033 (mark_memory): Also mark Lisp_Objects by fetching pointer words
10034 and widening them to Lisp_Objects. This would work even if
10035 USE_LSB_TAG is defined and wide integers are used, which might
10036 happen in a future version of Emacs.
10038 2012-02-25 Chong Yidong <cyd@gnu.org>
10040 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
10043 * xselect.c (Fx_selection_exists_p): Doc fix.
10044 (x_clipboard_manager_save_all): Print an informative message
10045 before saving to clipboard manager.
10047 2012-02-24 Chong Yidong <cyd@gnu.org>
10049 * keyboard.c (process_special_events): Handle all X selection
10050 requests in kbd_buffer, not just the next one (Bug#8869).
10052 2012-02-23 Chong Yidong <cyd@gnu.org>
10054 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
10055 call when setting menu-bar-lines and tool-bar-lines parameters.
10056 (unwind_create_frame_1): New helper function.
10058 * window.c (inhibit_window_configuration_change_hook): New var.
10059 (run_window_configuration_change_hook): Obey it.
10060 (syms_of_window): Initialize it.
10062 2012-02-22 Chong Yidong <cyd@gnu.org>
10064 * xterm.c (x_draw_image_relief): Add missing type check for
10065 Vtool_bar_button_margin (Bug#10743).
10067 2012-02-21 Chong Yidong <cyd@gnu.org>
10069 * fileio.c (Vfile_name_handler_alist): Doc fix.
10071 * buffer.c (Fget_file_buffer): Protect against invalid file
10072 handler return value.
10074 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
10076 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
10077 when computing $valmask.
10079 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
10080 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
10081 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
10082 It's useless in that case, and it can cause problems on hosts
10083 that allocate halves of EMACS_INT values separately.
10084 Reported by Dan Horák. Diagnosed by Andreas Schwab in
10085 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
10086 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
10087 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
10088 it avoids undefined behavior on hosts where shifting right by more
10089 than the word width has undefined behavior.
10091 2012-02-19 Chong Yidong <cyd@gnu.org>
10093 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
10094 (Funhandled_file_name_directory, Ffile_name_as_directory)
10095 (Fdirectory_file_name, Fexpand_file_name)
10096 (Fsubstitute_in_file_name): Protect against invalid file handler
10097 return values (Bug#10845).
10099 2012-02-18 Eli Zaretskii <eliz@gnu.org>
10101 * .gdbinit (pitx): Fix incorrect references to fields of the
10104 2012-02-17 Chong Yidong <cyd@gnu.org>
10106 * syntax.c (Fscan_lists): Doc fix (Bug#10833).
10108 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>
10110 * image.c (MAX_IMAGE_SIZE): Increase from 6.0 to 10.0; see
10111 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
10113 2012-02-15 Chong Yidong <cyd@gnu.org>
10115 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
10116 marked as special. Also, starting docstrings with * is obsolete.
10118 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
10120 * gnutls.c (emacs_gnutls_write): Fix last change.
10122 2012-02-13 Lars Ingebrigtsen <larsi@gnus.org>
10124 * gnutls.c (emacs_gnutls_write): Set errno appropriately for
10127 2012-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
10129 * keymap.c (Fsingle_key_description): Handle char ranges.
10131 2012-02-12 Chong Yidong <cyd@gnu.org>
10133 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
10134 as that creates a dangerous corner case.
10136 * window.c (Fdelete_window_internal): Invalidate the mouse
10137 highlight (Bug#9904).
10139 2012-02-12 Glenn Morris <rgm@gnu.org>
10141 * xselect.c (Fx_own_selection_internal)
10142 (Fx_get_selection_internal, Fx_disown_selection_internal)
10143 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
10144 * nsselect.m (Fx_own_selection_internal)
10145 (Fx_disown_selection_internal, Fx_selection_exists_p)
10146 (Fx_selection_owner_p, Fx_get_selection_internal):
10147 Sync docs and argument specs with the xselect.c versions.
10149 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
10151 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
10153 2012-02-11 Eli Zaretskii <eliz@gnu.org>
10155 * w32select.c (Fx_selection_exists_p): Sync doc string and
10156 argument list with xselect.c. (Bug#10783)

10163 * fns.c (Fsecure_hash): Doc fix.
10165 2012-02-09 Kenichi Handa <handa@m17n.org>
10167 * coding.c (produce_chars): Fix updating of src_end (Bug#10701).
10169 2012-02-07 Chong Yidong <cyd@gnu.org>
10171 * buffer.c (Fbuffer_local_variables)
10172 (buffer_lisp_local_variables): Handle unbound vars correctly;
10173 don't let Qunbound leak into Lisp.
10175 2012-02-07 Glenn Morris <rgm@gnu.org>
10177 * image.c (Fimagemagick_types): Doc fix.
10179 * image.c (imagemagick-render-type): Change it from a lisp object
10180 to an integer. Move the doc here from the lisp manual.
10181 Treat all values not equal to 0 the same.
10183 2012-02-06 Chong Yidong <cyd@gnu.org>
10185 * doc.c (store_function_docstring): Avoid applying docstring of
10186 alias to base function (Bug#2603).
10188 2012-02-04 Andreas Schwab <schwab@linux-m68k.org>
10190 * .gdbinit (pp1, pv1): Remove redundant defines.
10193 2012-02-04 Chong Yidong <cyd@gnu.org>
10195 * nsterm.m: Declare a global (Bug#10694).
10197 2012-02-04 Eli Zaretskii <eliz@gnu.org>
10199 * w32.c (get_emacs_configuration_options):
10200 Include --enable-checking, if specified, in the return value.
10202 2012-02-04 Martin Rudalics <rudalics@gmx.at>
10204 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
10205 after rounding frame sizes. (Bug#9723)
10207 2012-02-04 Eli Zaretskii <eliz@gnu.org>
10209 * keyboard.c (adjust_point_for_property): Don't position point
10210 before BEGV. (Bug#10696)
10212 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
10214 Handle overflow when computing char display width (Bug#9496).
10215 * character.c (char_width): Return EMACS_INT, not int.
10216 (char_width, c_string_width): Check for overflow when
10217 computing the width; this is possible now that individual
10218 characters can have unbounded width. Problem introduced
10219 by merge from Emacs 23 on 2012-01-19.
10221 2012-02-02 Michael Albinus <michael.albinus@gmx.de>
10223 * dbusbind.c (Fdbus_register_method): Mention the return value
10224 :ignore in the docstring.
10226 2012-02-02 Glenn Morris <rgm@gnu.org>
10228 * callproc.c (Fcall_process, Fcall_process_region): Doc fix.
10230 * nsterm.m (syms_of_nsterm) <x-toolkit-scroll-bars>:
10231 Unconditionally set to t. (Bug#10673)

10233 * w32term.c (syms_of_w32term) <x-toolkit-scroll-bars>:
10234 * xterm.c (syms_of_xterm) <x-toolkit-scroll-bars>: Doc fix.
10236 2012-02-02 Kenichi Handa <handa@m17n.org>
10238 (x_produce_glyphs): Cancel previous change. If cmp->glyph_len is
10239 0, do not call append_composite_glyph.
10241 2012-02-02 Kenichi Handa <handa@m17n.org>
10243 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
10245 (x_produce_glyphs): If the component of a composition is a null
10246 string, set it->pixel_width to 1 to avoid zero-width glyph.
10248 2012-02-01 Eli Zaretskii <eliz@gnu.org>
10250 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
10251 first 2 arguments are identical. This makes inserting large
10252 output from a subprocess an order of magnitude faster on
10253 MS-Windows, where all sbrk'ed memory is always contiguous.
10255 2012-01-31 Glenn Morris <rgm@gnu.org>
10257 * nsterm.m (syms_of_nsterm) <x-toolkit-scroll-bars>:

10754 (ALIGN_GCTYPEBITS) [_MSC_VER]: Define.
10755 (DECL_ALIGN) [_MSC_VER]: Use it, as MSVC doesn't like bit ops in
10756 this macro definition.
10758 * s/ms-w32.h (tzname): Redirect to _tzname for all values of

10783 * xdisp.c (redisplay_window): If cursor row is not fully visible
10784 after recentering, and scroll-conservatively is set to a large
10785 number, scroll window by a few more lines to make the cursor fully
10786 visible and out of scroll-margin. (Bug#10105)
10787 (start_display): Don't move to the next line if the display should
10788 start at a newline that is part of a display vector or an overlay
10789 string. (Bug#10119)

10870 Problem reported by Andreas Schwab in
10871 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
10872 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
10873 is set, removing the need for VIRT_ADDRESS_VARIES.
10874 (PURE_P): Use a more-efficient implementation that needs just one
10875 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
10876 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
10877 to 4 (xorl, subq, cmpq, setbe).
10878 * alloc.c (pure): Always extern now, since that's the
10879 VIRT_ADDR_VARIES behavior.
10880 (PURE_POINTER_P): Use a single comparison, not two, for
10881 consistency with the new puresize.h.
10882 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
10883 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

10889 (erase_phys_cursor, update_window_cursor, show_mouse_face)
10890 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
10891 behave as if the cursor position were at the window margin.
10893 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
10894 and the cursor position is out of bounds, behave as if the cursor
10895 position were at the window margin. (Bug#10075)
10897 2011-11-18 Chong Yidong <cyd@gnu.org>
10899 * window.c (Fwindow_combination_limit): Make first argument

10918 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
10920 * xdisp.c (row_hash): New function, body extracted from
10921 compute_line_metrics.
10922 (compute_line_metrics): Call row_hash, instead of computing the
10925 * dispnew.c (verify_row_hash): Call row_hash for computing the
10926 hash code of a row, instead of duplicating code from xdisp.c.
10928 * dispextern.h (row_hash): Add prototype.
10930 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>

10958 (Fsplit_window_internal, saved_window)
10959 (Fset_window_configuration, save_window_save): Rename all
10960 occurrences of window_nest to window_combination_limit.

10966 2011-11-14 Eli Zaretskii <eliz@gnu.org>
10968 * xdisp.c (display_line): Move the call to
10969 highlight_trailing_whitespace before the call to
10970 compute_line_metrics, since the latter needs to see the final
10971 faces of all the glyphs to compute ROW's hash value.
10972 Fixes assertion violations in row_equal_p. (Bug#10035)
10974 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
10976 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,
10977 just return (bug#10044).
10979 2011-11-12 Eli Zaretskii <eliz@gnu.org>
10981 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
10982 with user-defined heap size. Bump the default size of the temacs

10986 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
10987 current_matrix and desired_matrix. (Bug#9990)
10988 (verify_row_hash) [XASSERTS]: New function.

11033 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
11035 Avoid some portability problems by eschewing 'extern inline' functions.
11036 The trivial performance wins aren't worth the portability hassles; see
11037 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
11039 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

11105 * xmenu.c (cleanup_widget_value_tree): New function.
11106 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of

11113 (window_box_width, window_box_left, window_box_left_offset)
11114 (window_box_right, window_box_right_offset): Declare extern.
11115 Otherwise, these inline functions do not conform to C99 and
11116 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
11117 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
11118 * intervals.c (adjust_intervals_for_insertion)

11121 (static_offset_intervals): Remove.
11122 (offset_intervals): Rewrite using the old contents of
11123 static_offset_intervals. The old version didn't conform to C99
11124 because an extern inline function contained a reference to an
11125 identifier with static linkage.

11177 * nsfns.m: Declare image_cache_refcount if GLYPH_DEBUG.
11178 (unwind_create_frame): New function (Bug#9943).
11179 (Fx_create_frame): Restructure code to be more similar to the one in
11180 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).

11196 Support MSVC build with newer versions of Visual Studio.
11197 * makefile.w32-in (TAGS-gmake): Don't use $(patsubst ...), as

11202 which are not supported by MSVC.
11203 (Lisp_Symbol, Lisp_Misc_Any, Lisp_Marker, Lisp_Misc_Overlay)

11220 (fstat, stat, utime) [_MSC_VER]: Redirect to their sys_* cousins.
11221 (malloc, free, realloc, calloc) [_MSC_VER]: Always redirect to the
11223 (alloca) [_MSC_VER]: Define to _alloca.
11225 * lisp.h (DECL_ALIGN) [_MSC_VER]: Define for MSVC.
11227 * regex.c <re_char> [_MSC_VER]: A separate definition for MSVC.

11231 * xdisp.c (note_mouse_highlight): If either of
11232 previous/next-single-property-change returns nil, treat that as
11233 the beginning or the end of the buffer. (Bug#9955)
11235 2011-11-04 Jan Djärv <jan.h.d@swipnet.se>
11237 * gtkutil.c (xg_make_tool_item): Add callbacks if one of wimage or
11238 label is not null (Bug#9951).

11257 * xdisp.c (mouse_face_from_buffer_pos): Fix a typo in a comment.
11258 Don't stop backward scan on the continuation glyph, even though
11259 its CHARPOS is positive.
11260 (mouse_face_from_buffer_pos, note_mouse_highlight):
11261 Rename cover_string to disp_string.
11263 2011-11-01 Martin Rudalics <rudalics@gmx.at>
11265 * window.c (temp_output_buffer_show): Don't use
11266 Vtemp_buffer_show_specifiers.
11267 (Vtemp_buffer_show_specifiers): Remove unused variable.
11269 2011-10-30 Eli Zaretskii <eliz@gnu.org>
11271 * xdisp.c (try_cursor_movement): Make sure ROW isn't decremented
11272 past the beginning of the current glyph matrix.
11274 2011-10-30 Adam Sjøgren <asjo@koldfront.dk> (tiny change)
11276 * xterm.c: Include X11/Xproto.h if HAVE_GTK3.
11277 (x_error_handler): Ignore BadMatch for X_SetInputFocus for
11278 HAVE_GTK3 (Bug#9869).
11280 * gtkutil.c (xg_win_to_widget, xg_event_is_for_menubar): Initialize

11283 * xterm.h (x_display_info): Add Xatom_net_wm_state_hidden (Bug#9893).
11285 * xterm.c: Declare x_handle_net_wm_state to return int.
11286 (handle_one_xevent): Check if we are iconified but don't have
11287 _NET_WM_STATE_HIDDEN. If do, treat as deiconify (Bug#9893).
11288 (get_current_wm_state): Return non-zero if not hidden,
11289 check for _NET_WM_STATE_HIDDEN (Bug#9893).

11296 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
11297 so that this new function doesn't get optimized away by a
11298 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
11300 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
11302 * frame.h (MOUSE_HL_INFO): Remove excess parens.
11304 2011-10-29 Eli Zaretskii <eliz@gnu.org>

11317 * minibuf.c (read_minibuf_noninteractive): Allow reading empty
11320 2011-10-29 Glenn Morris <rgm@gnu.org>
11322 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
11323 Not clear what it was for, and it causes various bugs. (Bug#9839)
11325 2011-10-28 Eli Zaretskii <eliz@gnu.org>
11327 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
11328 possible random value that matches one of those tested as
11329 condition to clear the mouse face.
11331 2011-10-28 Chong Yidong <cyd@gnu.org>
11333 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.

11343 2011-10-28 Juanma Barranquero <lekktu@gmail.com>
11345 * w32font.c (w32_load_unicows_or_gdi32): Add missing return.
11347 2011-10-28 Eli Zaretskii <eliz@gnu.org>
11349 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
11350 <oslsachem@gmail.com> for helping to debug this.
11352 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
11353 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
11354 (g_b_init_get_glyph_outline_w): New static variables.

11358 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
11360 (w32font_open_internal, compute_metrics):
11361 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
11362 instead of calling the "wide" APIs directly.
11364 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
11366 * w32.h (syms_of_w32font): Add prototype.
11368 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
11370 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
11371 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
11372 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
11373 (Fmove_to_window_line): Doc fix.
11375 2011-10-27 Chong Yidong <cyd@gnu.org>
11377 * process.c (make_process): Set gnutls_state to NULL.
11379 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
11380 non-NULL, regardless of GNUTLS_INITSTAGE.
11381 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
11382 an error. Set process slots as soon as we allocate them.
11384 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
11386 2011-10-27 Chong Yidong <cyd@gnu.org>
11388 * gnutls.c (emacs_gnutls_deinit): New function.

11393 (deactivate_process): Call emacs_gnutls_deinit.
11395 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
11397 * image.c (x_create_x_image_and_pixmap):
11398 * w32.c (sys_rename, w32_delayed_load):
11399 * w32font.c (fill_in_logfont):

11405 extracted from Fw32_default_color_map.
11406 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
11408 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
11410 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
11412 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
11414 * keyboard.c (test_undefined): New function (bug#9751).
11415 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
11417 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
11419 * sysdep.c (init_sys_modes): Fix the check for the controlling
11420 terminal (Bug#6649).
11422 2011-10-20 Eli Zaretskii <eliz@gnu.org>
11424 * dispextern.h (struct bidi_it): New member next_en_type.
11426 * bidi.c (bidi_line_init): Initialize the next_en_type member.
11427 (bidi_resolve_explicit_1): When next_en_pos is valid for the
11428 current character, check also for next_en_type being WEAK_EN.
11429 (bidi_resolve_weak): Don't enter the expensive loop if the current
11430 position is before next_en_pos. Record the bidi type of the first
11431 non-ET, non-BN character we find, in addition to its position.
11432 (bidi_level_of_next_char): Invalidate next_en_type when
11433 next_en_pos is over-stepped.
11435 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
11437 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
11438 * editfns.c: Rewrite current-time-zone so that it invokes
11439 the equivalent of (format-time-string "%Z") to get the time zone name.
11440 This fixes a bug when the time zone name contains characters that
11441 need converting from the system time locale to Emacs internal format.
11442 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
11443 that patch fixed format-time-string to do the conversion, but
11444 I forgot to fix current-time-zone.
11445 (format_time_string): New function, containing most of
11446 what Fformat_time_string used to contain.
11447 (Fformat_time_string): Rewrite in terms of format_time_string.
11448 This doesn't change this function's behavior.
11449 (current-time-zone): Rewrite to use format_time_string.
11450 This fixes the bug reported by Michael Schierl in
11451 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
11452 Jason Rumney's 2007-06-07 change worked around this bug, but
11454 * systime.h (tzname, timezone): Remove no-longer-used declarations.
11456 2011-10-19 Eli Zaretskii <eliz@gnu.org>
11458 * xdisp.c (start_display): If the character at POS is displayed
11459 via a display vector, reset IT->current.dpvec_index to zero.
11460 (try_window_reusing_current_matrix): If a line ends in a display
11461 vector or the next line starts in a display vector, continue
11462 redrawing the window even though the character position of
11463 start_row was reached.
11466 2011-10-18 Chong Yidong <cyd@gnu.org>
11468 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
11469 with nobreak-char-display too.
11471 2011-10-18 Eli Zaretskii <eliz@gnu.org>
11473 Fix part 3 of bug#9771.
11474 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
11475 (bidi_resolve_neutral): Don't enter the expensive loop looking for
11476 non-neutral characters if the current character is a paragraph
11477 separator (a.k.a. Newline). This avoids running the same
11478 expensive loop twice, once when we consume the preceding newline
11479 and the other time when the line actually needs to be displayed.
11480 Avoid the loop when we see neutrals on the base embedding level
11481 following a character whose directionality is the same as the
11482 paragraph's. This avoids running the expensive loop when a line
11483 ends in a long sequence of neutrals, like control characters.
11484 Add assertion against STRONG_AL type. Slightly rearrange code
11485 that determines the type of a neutral given the first non-neutral
11487 (bidi_level_of_next_char): Set next_en_pos to zero when
11488 invalidating its info.
11490 2011-10-17 Eli Zaretskii <eliz@gnu.org>
11492 * xdisp.c (push_display_prop): Determine whether to record string
11493 or buffer position by IT->string, not by IT->method. Allow
11494 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
11495 (move_it_vertically_backward): Don't look for character position
11496 immediately after the newline when in a continuation line.
11499 2011-10-15 Martin Rudalics <rudalics@gmx.at>
11501 * window.c (coordinates_in_window): Rewrite and delabelize
11502 vertical border check. (Bug#5357) (Bug#9618)
11504 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
11506 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
11507 errors in XSetWindowBorder (bug#9310).
11509 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
11511 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
11512 avoid crash when xmalloc overrun checking is enabled.
11514 2011-10-13 Eli Zaretskii <eliz@gnu.org>
11516 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
11517 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
11518 cursor motion with <left> and <right> arrow keys.
11520 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
11521 some callers set that themselves.
11523 2011-10-12 Eli Zaretskii <eliz@gnu.org>
11525 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
11526 display string and the previous row comes from the same string and
11527 is empty. (Bug#9739) (Bug#9738)
11529 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
11531 * doc.c (get_doc_string): Encode file name (bug#9735).
11533 2011-10-12 Eli Zaretskii <eliz@gnu.org>
11535 * bidi.c (bidi_level_of_next_char):
11536 * xdisp.c (get_visually_first_element): Remove old incorrect
11537 comments regarding the Unicode Line Separator character.
11539 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
11541 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
11543 * alloc.c (Fgc_status): Do not access beyond zombies array
11544 boundary if nzombies > MAX_ZOMBIES.
11545 * alloc.c (dump_zombies): Add missing format specifier.
11547 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
11549 * xdisp.c (set_cursor_from_row): Simplify conditionals,
11550 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
11552 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
11553 Some packages use them to denote characters with modifiers.
11555 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
11557 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
11558 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
11559 matching a pp-number. Rename parameter var to var1.
11561 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
11563 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
11565 2011-10-08 Glenn Morris <rgm@gnu.org>
11567 * callint.c (Fcall_interactively): Give a more explicit error for the
11568 'c' case with a non-character input. (Bug#8479)
11570 2011-10-08 Eli Zaretskii <eliz@gnu.org>
11572 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
11574 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
11575 lines that are hscrolled on the left.
11577 * dispnew.c (buffer_posn_from_coords): Account for a possible
11578 presence of header-line. (Bug#4426)
11580 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
11582 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
11583 Don't advertise functionality which we discourage or doesn't work.
11585 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
11587 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
11588 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
11589 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
11590 this makes Emacs dump core during garbage collection on rare
11591 occasions. sizeof is obviously inferior to offsetof here, so
11592 stick with offsetof.
11593 (GC_POINTER_ALIGNMENT): New macro.
11594 (mark_memory): Omit 3rd (offset) arg; caller changed.
11595 Don't assume EMACS_INT alignment is the same as pointer alignment.
11597 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
11599 * keyboard.c (read_key_sequence_remapped): New var.
11600 (read_key_sequence): Compute remapping in the right buffer.
11601 (command_loop_1): Use read_key_sequence's remapping directly.
11603 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
11605 * dired.c (file_name_completion): Don't expand file name.
11606 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
11607 before checking file name handler.
11609 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
11610 they've been requested explicitly (bug#9591).
11612 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
11614 * keymap.c (Fsingle_key_description): Use make_specified_string
11615 instead of build_string to build string from push_key_description.
11618 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
11620 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
11621 This fixes a Y2038 bug on 64-bit hosts.
11622 * buffer.c (reset_buffer):
11623 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
11624 (Fclear_buffer_auto_save_failure):
11625 Use 0, not -1, to represent an unset failure time, since time_t
11626 might not be signed.
11628 Remove dependency on glibc malloc internals.
11629 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11630 Move back here from lisp.h, but with their new implementations.
11631 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
11632 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
11633 * charset.c (charset_table_init): New static var.
11634 (syms_of_charset): Use it instead of xmalloc. This removes a
11635 dependency on glibc malloc internals. See Eli Zaretskii's comment in
11636 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
11637 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11638 Move back to alloc.c.
11639 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
11640 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
11642 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
11644 * nsterm.m (windowDidResize): Call x_set_window_size only when
11645 ns_in_resize is true. Otherwise set pixelwidth/height and
11646 call change_frame_size (Bug#9628).
11648 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
11650 Port --enable-checking=all to Fedora 14 x86-64.
11651 * charset.c (syms_of_charset): Also account for glibc malloc's
11652 internal overhead when calculating the initial malloc maximum.
11654 Port --enable-checking=all to Fedora 14 x86.
11655 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11657 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
11658 (overrun_check_realloc, overrun_check_free):
11659 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
11660 That way, xmalloc returns a properly-aligned pointer even if
11661 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
11662 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
11663 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
11664 into account when calculating the initial malloc maximum.
11665 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11666 Move here from alloc.c, so that charset.c can use it too.
11667 Properly align; the old code wasn't right for common 32-bit hosts
11668 when configured with --enable-checking=all.
11669 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
11670 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
11672 2011-09-29 Eli Zaretskii <eliz@gnu.org>
11674 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
11677 2011-09-28 Eli Zaretskii <eliz@gnu.org>
11679 * xdisp.c (compute_display_string_end): If there's no display
11680 string at CHARPOS, return -1.
11682 * bidi.c (bidi_fetch_char): When compute_display_string_end
11683 returns a negative value, treat the character as a normal
11684 character not covered by a display string. (Bug#9624)
11686 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
11688 * lread.c (Fread_from_string): Fix typo in docstring.
11690 2011-09-27 Eli Zaretskii <eliz@gnu.org>
11692 * xdisp.c (handle_invisible_prop): If invisible text ends on a
11693 newline, reseat the iterator instead of bidi-iterating there one
11694 character at a time. (Bug#9610)
11695 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
11696 TO_CHARPOS if the bidi iterator is at base embedding level.
11698 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
11700 * lread.c (readevalloop): Use correct code for NBSP.
11701 (read1): Likewise. (Bug#9608)
11703 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
11705 * dbusbind.c (Fdbus_register_signal): When service is not
11706 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
11708 2011-09-25 Glenn Morris <rgm@gnu.org>
11710 * buffer.c (truncate-lines): Doc fix.
11712 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
11714 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
11715 (Fset_window_next_buffers): Doc fix.
11717 2011-09-24 Glenn Morris <rgm@gnu.org>
11719 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
11721 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
11723 Fix minor problems found by static checking.
11724 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
11725 * indent.c (Fvertical_motion): Fix == vs = typo.
11727 2011-09-24 Eli Zaretskii <eliz@gnu.org>
11729 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
11730 Default value is now t. Doc fix.
11732 * indent.c (Fvertical_motion): Compute and apply the overshoot
11733 logic when moving up, not only when moving down. Fix the
11734 confusing name and values of the it_overshoot_expected variable;
11735 logic changes accordingly. (Bug#9254) (Bug#9549)
11737 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
11738 CHARPOS is covered by a display string which includes newlines.
11739 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
11740 is covered by a display string with embedded newlines.
11742 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
11744 * dbusbind.c (Fdbus_register_signal): Add match rule to
11745 Vdbus_registered_objects_table. (Bug#9581)
11746 (Fdbus_register_method, Vdbus_registered_objects_table):
11749 2011-09-24 Jim Meyering <meyering@redhat.com>
11751 do not ignore write error for any output size
11752 The previous change was incomplete.
11753 While it makes emacs --batch detect the vast majority of stdout
11754 write failures, errors were still ignored whenever the output size is
11755 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
11756 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
11757 && echo FAIL: ignored write error
11758 FAIL: ignored write error
11759 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
11760 && echo FAIL: ignored write error
11761 FAIL: ignored write error
11762 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
11764 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
11766 * emacs.c (Fkill_emacs): In noninteractive mode exit
11767 non-successfully if a write error occurred on stdout. (Bug#9574)
11769 2011-09-21 Eli Zaretskii <eliz@gnu.org>
11771 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
11774 * dispextern.h (struct it): Update the comment documenting what
11777 2011-09-20 Eli Zaretskii <eliz@gnu.org>
11779 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
11780 a display string, extend search for cursor position to end of row.
11781 (find_row_edges): If the row ends in a newline from a display
11782 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
11783 Handle the case of a display string with multiple newlines.
11784 (Fcurrent_bidi_paragraph_direction): Fix search for previous
11785 non-empty line. Fixes confusing cursor motion with arrow keys at
11786 the beginning of a line that starts with whitespace.
11788 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
11790 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
11793 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
11795 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
11796 boolean (Bug#9154).
11798 2011-09-18 Eli Zaretskii <eliz@gnu.org>
11800 * xdisp.c (display_line): Record maximum and minimum buffer
11801 positions even if no glyphs were produced (e.g., by a zero-width
11802 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
11803 buffer positions that will be removed from the glyph row because
11805 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
11806 column is beyond frame width: don't subtract 1 "pixel" when
11807 computing width of the stretch.
11808 (reseat_at_next_visible_line_start): Undo the change made on
11809 2011-09-17 that saved paragraph information and restored it after
11810 the call to `reseat'. (Bug#9545)
11812 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11814 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
11815 and turn window cursor on if cleared (Bug#9415).
11817 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
11819 * search.c (boyer_moore): Take unibyte characters from pattern
11820 literally. (Bug#9458)
11822 2011-09-18 Eli Zaretskii <eliz@gnu.org>
11824 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
11826 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
11828 Fix minor problem found by static checking.
11829 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
11830 initialized, to pacify gcc -Wuninitialized.
11832 * fileio.c: Report proper errno when syscall falls.
11833 (Finsert_file_contents): Save and restore errno,
11834 so that report_file_error outputs the correct diagnostic.
11835 (Fwrite_region) [CLASH_DETECTION]: Likewise.
11837 2011-09-18 Eli Zaretskii <eliz@gnu.org>
11839 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
11841 2011-09-17 Eli Zaretskii <eliz@gnu.org>
11843 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
11844 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
11846 2011-09-17 Eli Zaretskii <eliz@gnu.org>
11848 * xdisp.c (reseat_at_next_visible_line_start): Keep information
11849 about the current paragraph and restore it after the call to reseat.
11851 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
11852 (bidi_find_paragraph_start): Search back for paragraph beginning
11853 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
11854 (bidi_move_to_visually_next): Only trigger paragraph-related
11855 computations when the last character is a newline or at EOB, not
11856 just any NEUTRAL_B. (Bug#9470)
11858 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
11859 truncated lines if point is covered by a display string. (Bug#9524)
11861 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
11863 * xselect.c: Relax test for outgoing X longs (Bug#9498).
11864 (cons_to_x_long): New function.
11865 (lisp_data_to_selection_data): Use it. Correct the test for
11866 short-versus-long data; it was negated. Break out of vector
11867 loop, for efficiency, when a long datum is discovered.
11869 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
11871 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
11873 2011-09-16 Eli Zaretskii <eliz@gnu.org>
11875 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
11876 GCC PR/17406) by declaring this function with external scope.
11878 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
11880 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
11881 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
11883 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
11885 * editfns.c (Fformat): Correctly handle text properties on "%%".

11895 of TAB characters in a composition.
11897 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
11899 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
11900 This occurs when processing a multibyte format.
11901 Problem reported by Wolfgang Jenker.
11903 2011-09-15 Johan Bockgård <bojohan@gnu.org>
11905 * xdisp.c (try_cursor_movement): Only check for exact match if
11906 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
11908 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
11910 Remove unused external symbols.
11911 * dispextern.h (calc_pixel_width_or_height): Remove decl.
11912 * xdisp.c (calc_pixel_width_or_height): Now static.
11913 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
11914 * indent.c (check_display_width):
11915 * w32term.c: Fix comment to match code.
11916 * xterm.c, xterm.h (x_catching_errors): Remove.
11918 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
11920 * xselect.c: Use signed conversions more consistently (Bug#9498).
11921 (selection_data_to_lisp_data): Assume incoming selection data are
11922 signed integers, not unsigned. This is to be consistent with
11923 outgoing selection data, which was modified to use signed integers
11924 in as part of the fix to Bug#9196 in response to Jan D.'s comment
11925 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
11926 expects long, not unsigned long.
11928 2011-09-14 Eli Zaretskii <eliz@gnu.org>
11930 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
11931 computation of loop end. Reported by Johan Bockgård
11934 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
11936 * frame.c (Fother_visible_frames_p): Function deleted.
11938 2011-09-12 Eli Zaretskii <eliz@gnu.org>
11940 * indent.c (compute_motion): Process display vector front to back
11941 rather than the other way around. (Bug#2496)
11943 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
11945 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
11947 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
11949 * minibuf.c (Fread_from_minibuffer): Doc fix.
11951 2011-09-11 Eli Zaretskii <eliz@gnu.org>
11953 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
11954 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
11956 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
11958 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
11959 value for non-existent files.
11961 2011-09-11 Eli Zaretskii <eliz@gnu.org>
11963 * fileio.c (Finsert_file_contents): If the file cannot be opened,
11964 set its "size" to -1. This will set the modtime_size field of
11965 the corresponding buffer to -1, which is what
11966 verify-visited-file-modtime expects for files that do not exist.
11969 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
11971 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
11973 * lisp.h: ... from here. push_key_description is no longer
11974 defined in keyboard.c, so its declaration should not be in
11975 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
11976 logically belongs with push_key_description.
11978 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
11980 * buffer.h: Include <sys/types.h> instead of <time.h>.
11981 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
11982 Problem reported by Herbert J. Skuhra.
11984 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
11986 * xml.c (parse_region): Make the parsing work for
11987 non-comment-starting XML files again (bug#9144).
11989 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
11991 * image.c (gif_load): Fix calculation of bottom and right corner.
11994 2011-09-10 Eli Zaretskii <eliz@gnu.org>
11996 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
11997 redisplay in small windows.
11999 2011-09-09 Eli Zaretskii <eliz@gnu.org>
12001 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
12003 2011-09-08 Martin Rudalics <rudalics@gmx.at>
12005 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
12006 Operate on live windows only.
12008 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
12010 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
12012 2011-09-07 Eli Zaretskii <eliz@gnu.org>
12014 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
12015 only under bidi iteration.
12017 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
12019 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
12021 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
12023 isnan: Fix porting problem to Solaris 10 with bundled gcc.
12024 Without this fix, the command to link temacs failed due to an
12025 undefined symbol __builtin_isnan. This is because
12026 /usr/include/iso/math_c99.h #defines isnan(x) to
12027 __builtin_isnan(x), but the bundled gcc, which identifies itself
12028 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
12030 * floatfns.c (isnan): #undef, and then #define to a clone of
12032 (Fisnan): Always define, since it's always available now.
12033 (syms_of_floatfns): Always define isnan at the Lisp level.
12035 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
12037 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
12039 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
12041 * fileio.c: Fix bugs with large file offsets (Bug#9428).
12042 The previous code assumed that file offsets (off_t values) fit in
12043 EMACS_INT variables, which is not true on typical 32-bit hosts.
12044 The code messed up by falsely reporting buffer overflow in cases
12045 such as (insert-file-contents "big" nil 1 2) into an empty buffer
12046 when "big" contains more than 2**29 bytes, even though this
12047 inserts just one byte and does not overflow the buffer.
12048 (Finsert_file_contents): Store file offsets as off_t
12049 values, not as EMACS_INT values. Check for overflow when
12050 converting between EMACS_INT and off_t. When checking for
12051 buffer overflow or for overlap, take the offsets into account.
12052 Don't use EMACS_INT for small values where int suffices.
12053 When checking for overlap, fix a typo: ZV was used where
12054 ZV_BYTE was intended.
12055 (Fwrite_region): Don't assume off_t fits into 'long'.
12056 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
12058 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
12060 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
12062 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
12064 sprintf-related integer and memory overflow issues (Bug#9412).
12066 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
12067 (esprintf, exprintf, evxprintf): New functions.
12068 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
12069 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
12070 (modify_event_symbol): Do not assume that the length of
12071 name_alist_or_stem is safe to alloca and fits in int.
12072 (Fexecute_extended_command): Likewise for function name and binding.
12073 (Frecursion_depth): Wrap around reliably on integer overflow.
12074 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
12075 since some callers pass EMACS_INT values.
12076 (Fsingle_key_description): Don't crash if symbol name contains more
12077 than MAX_ALLOCA bytes.
12078 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
12079 (get_minibuffer): Arg is now EMACS_INT, not int.
12080 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
12081 (esprintf, exprintf, evxprintf): New decls.
12082 * window.h (command_loop_level, minibuf_level): Reflect API changes.
12084 * dbusbind.c (signature_cat): New function.
12085 (xd_signature, Fdbus_register_signal):
12086 Do not overrun buffer; instead, report string overflow.
12088 * dispnew.c (add_window_display_history): Don't overrun buffer.
12089 Truncate instead; this is OK since it's just a log.
12091 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
12092 even if the time zone offset is outlandishly large.
12093 Don't mishandle offset == INT_MIN.
12095 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
12096 when creating daemon; the previous buffer-overflow check was incorrect.
12098 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
12099 which has the guts of the old verror function.
12101 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
12102 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
12104 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
12105 (font_unparse_xlfd): Don't blindly alloca long strings.
12106 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
12107 fits in int, when using sprintf. Use single snprintf to count
12108 length of string rather than counting it via multiple sprintfs;
12109 that's simpler and more reliable.
12110 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
12111 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
12112 sprintf, in case result does not fit in int.
12114 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
12115 (fontset_from_font): Print it.
12117 * frame.c (tty_frame_count): Now printmax_t, not int.
12118 (make_terminal_frame, set_term_frame_name): Print it.
12119 (x_report_frame_params): In X, window IDs are unsigned long,
12120 not signed long, so print them as unsigned.
12121 (validate_x_resource_name): Check for implausibly long names,
12122 and don't assume name length fits in 'int'.
12123 (x_get_resource_string): Don't blindly alloca invocation name;
12124 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
12127 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
12128 (xg_check_special_colors, xg_set_geometry):
12129 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
12131 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
12132 Use esprintf, not sprintf, in case result does not fit in int.
12134 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
12135 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
12136 it as a large positive number.

12138 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
12140 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
12141 in case result does not fit in int.
12143 * print.c (float_to_string): Detect width overflow more reliably.
12144 (print_object): Make sprintf buffer a bit bigger, to avoid potential
12145 buffer overrun. Don't assume list length fits in 'int'. Treat
12146 print length of 0 as 0, not as infinity; to be consistent with other
12147 uses of print length in this function. Don't overflow print length
12148 index. Don't assume hash table size fits in 'long', or that
12149 vectorlike size fits in 'unsigned long'.
12151 * process.c (make_process): Use printmax_t, not int, to format
12152 process-name gensyms.
12154 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
12156 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
12157 to avoid potential buffer overrun.
12159 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
12160 if X resource line is longer than 512 bytes.
12162 * xfns.c (x_window): Make sprintf buffer a bit bigger
12163 to avoid potential buffer overrun.
12165 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
12167 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
12169 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
12171 Integer overflow fixes for scrolling, etc.
12172 Without these, Emacs silently mishandles large integers sometimes.
12173 For example, "C-u 4294967297 M-x recenter" was treated as if
12174 it were "C-u 1 M-x recenter" on a typical 64-bit host.
12176 * xdisp.c (try_window_id): Check Emacs fixnum range before
12177 converting to 'int'.
12179 * window.c (window_scroll_line_based, Frecenter):
12180 Check that an Emacs fixnum is in range before assigning it to 'int'.
12181 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
12182 values converted from Emacs fixnums.
12183 (Frecenter): Don't wrap around a line count if it is out of 'int'
12184 range; instead, treat it as an extreme value.
12185 (Fset_window_configuration, compare_window_configurations):
12186 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
12188 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
12189 that can exceed INT_MAX. Check that EMACS_INT value is in range
12190 before assigning it to the (possibly-narrower) index.
12191 (match_limit): Don't assume that a fixnum can fit in 'int'.
12193 * print.c (print_object): Use ptrdiff_t, not int, for index that can
12196 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
12197 (Fvertical_motion): Don't wrap around LINES values that don't fit
12198 in 'int'. Instead, treat them as extreme values. This is good
12199 enough for windows, which can't have more than INT_MAX lines anyway.
12201 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
12203 * Require libxml/parser.h to avoid compilation warning.
12205 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
12207 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
12208 since this reportedly can destroy thread storage.
12210 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
12212 * syntax.c (find_defun_start): Update all cache variables if
12213 exiting early (Bug#9401).
12215 2011-08-30 Eli Zaretskii <eliz@gnu.org>
12217 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
12219 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
12220 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
12221 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
12223 * term.c (tty_append_glyph): New function.
12224 (produce_stretch_glyph): Static function and its prototype deleted.
12226 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
12229 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
12231 * image.c (parse_image_spec): Check for nonnegative, not for positive,
12232 when checking :margin (Bug#9390).
12233 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
12234 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
12235 so that the name doesn't mislead. All uses changed.
12237 2011-08-28 Johan Bockgård <bojohan@gnu.org>
12239 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
12242 2011-08-27 Eli Zaretskii <eliz@gnu.org>
12244 * xdisp.c (move_it_to): Don't bail out early when reaching
12245 position beyond to_charpos, if we are scanning backwards.
12246 (move_it_vertically_backward): When DY == 0, make sure we get to
12247 the first character in the line after the newline.
12249 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
12251 * ccl.c: Improve and simplify overflow checking (Bug#9196).
12252 (ccl_driver): Do not generate an out-of-range pointer.
12253 (Fccl_execute_on_string): Remove unnecessary check for
12254 integer overflow, noted by Stefan Monnier in
12255 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
12256 Remove a FIXME that didn't need fixing.
12257 Simplify the newly-introduced buffer reallocation code.
12259 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
12261 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
12263 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
12265 Integer and memory overflow issues (Bug#9196).
12267 * doc.c (get_doc_string): Rework so that
12268 get_doc_string_buffer_size is the actual buffer size, rather than
12269 being 1 less than the actual buffer size; this makes xpalloc more
12272 * image.c (x_allocate_bitmap_record, cache_image):
12273 * xselect.c (Fx_register_dnd_atom):
12274 Simplify previous changes by using xpalloc.
12276 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
12277 since either will do and ptrdiff_t is convenient with xpalloc.
12279 * charset.c (charset_table_size)
12280 (struct charset_sort_data.priority): Now ptrdiff_t.
12281 (charset_compare): Don't overflow if priorities differ greatly.
12282 (Fsort_charsets): Don't assume list length fits in int.
12283 Check for size-calculation overflow when allocating sort data.
12284 (syms_of_charset): Allocate an initial charset table that is
12285 just under 64 KiB, to avoid problems with glibc malloc and mmap.
12287 * cmds.c (internal_self_insert): Check for size-calculation overflow.
12289 * composite.h (struct composition.glyph_len): Now int, not unsigned.
12290 The actual value is always <= INT_MAX, and leaving it unsigned made
12291 overflow checking harder.
12293 * dispextern.h (struct glyph_matrix.rows_allocated)
12294 (struct face_cache.size): Now ptrdiff_t, for convenience in use
12295 with xpalloc. The values are still always <= INT_MAX.
12297 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
12299 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
12300 (SAFE_NALLOCA): New macro.
12302 * region-cache.c (struct boundary.pos, find_cache_boundary)
12303 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
12304 (set_cache_region, invalidate_region_cache)
12305 (revalidate_region_cache, know_region_cache, region_cache_forward)
12306 (region_cache_backward, pp_cache):
12307 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
12308 so that ptrdiff_t * can be passed to xpalloc.
12309 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
12310 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
12311 (pp_cache): Don't assume cache_len fits in int.
12312 * region-cache.h: Adjust extern decls to match.
12314 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
12315 EMACS_INT, since either will do, for xpalloc.
12317 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
12318 (xnmalloc, xnrealloc, xpalloc): New functions.
12320 * bidi.c (bidi_shelve_header_size): New constant.
12321 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
12322 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
12324 * bidi.c (bidi_cache_shrink):
12325 * buffer.c (overlays_at, overlays_in, record_overlay_string)
12327 Don't update size of array until after memory allocation succeeds,
12328 because xmalloc/xrealloc may not return.
12329 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
12330 now that we have proper integer overflow checking.
12331 (record_overlay_string, overlay_strings): Catch overflows when
12332 calculating size of overlay_str_buf.
12334 * callproc.c (Fcall_process): Check for size overflow when
12335 calculating size of args2.
12336 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
12337 Normally we prefer signed values, but sticking with ptrdiff_t would
12338 require adding more-complicated checks.
12340 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
12341 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
12342 Redo buffer-overflow calculations to avoid integer overflow.
12343 Add a FIXME comment where memory seems to be over-allocated.
12345 * character.c (Fstring): Check for size-calculation overflow.
12347 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
12348 unnecessary integer overflow. Check for size overflow.
12349 (encode_coding_object): Don't update size until xmalloc succeeds.
12351 * composite.c (get_composition_id): Check for overflow in glyph
12352 length calculations.
12354 Integer and memory overflow fixes for display code.
12355 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
12356 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
12357 (scrolling_window): Check for overflow in size calculations.
12358 (line_draw_cost, realloc_glyph_pool, add_row_entry):
12359 Don't assume glyph table len fits in int.

12361 (row_table_size): Now ptrdiff_t, not int.
12362 (scrolling_window): Avoid overflow in size calculations.
12363 Don't update size until allocation succeeds.
12364 * fns.c (concat): Check for overflow in size calculations.
12365 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
12366 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.

12369 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
12370 (get_doc_string): Check for size calculation overflow.
12371 Don't update size until allocation succeeds.
12372 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
12373 EMACS_INT, where ptrdiff_t will do.
12374 (Fsubstitute_command_keys): Check for string overflow.
12376 * editfns.c (set_time_zone_rule): Don't assume environment length
12378 (message_length): Now ptrdiff_t, not int.
12379 (Fmessage_box): Don't update size until allocation succeeds.
12380 Don't assume message length fits in int.
12381 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
12383 * emacs.c (main): Do not reallocate argv, since there is a null at
12384 the end that can be overwritten, and this way there's no need to
12385 worry about size-calculation overflow.
12386 (sort_args): Check for size-calculation overflow.
12388 * eval.c (init_eval_once, grow_specpdl): Don't update size until
12390 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
12392 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
12393 (x_set_scroll_bar_width, x_figure_window_size):
12394 Check for integer overflow.
12395 (x_set_alpha): Do not assume XINT fits in int.
12397 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
12398 This is for the members text_lines, text_cols, total_lines, total_cols,
12399 where the system imposes an 'int' limit.
12401 * fringe.c (Fdefine_fringe_bitmap):
12402 Don't update size until alloc works.
12404 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
12405 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
12407 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
12408 Check for size-calculation overflow.
12409 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
12410 do, as we prefer signed integers.
12411 (id_to_widget.max_size, id_to_widget.used)
12412 (xg_store_widget_in_map, xg_remove_widget_from_map)
12413 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
12414 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
12415 Use and return ptrdiff_t, not int.
12416 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
12417 * gtkutil.h: Change prototypes to match the above.
12419 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
12420 are duplicate now that they've been promoted to lisp.h.
12421 (x_allocate_bitmap_record, x_alloc_image_color)
12422 (make_image_cache, cache_image, xpm_load):
12423 Don't update size until alloc is done.
12424 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
12426 Check for size calculation overflow.
12427 (ct_colors_allocated_max): New constant.
12428 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid
12431 * keyboard.c (read_char, menu_bar_items, tool_bar_items)
12432 (read_char_x_menu_prompt, read_char_minibuf_menu_width)
12433 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
12434 Use ptrdiff_t, not int, to count maps.
12435 (read_char_minibuf_menu_prompt): Check for overflow in size
12436 calculations. Don't update size until allocation succeeds.
12437 Redo calculations to avoid overflow.
12438 * keyboard.h: Change prototypes to match the above.
12440 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
12442 (current_minor_maps): Check for size calculation overflow.
12443 * keymap.h: Change prototypes to match the above.
12445 * lread.c (read1, init_obarray): Don't update size until alloc done.
12447 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.
12448 (store_kbd_macro_char): Reorder multiplicands to avoid overflow.
12450 * nsterm.h (struct ns_color_table.size, struct ns_color_table.avail):
12451 Now ptrdiff_t, not int.
12452 * nsterm.m (ns_index_color): Use ptrdiff_t, not int, for table indexes.

12456 in size calculation.
12458 * region-cache.c (move_cache_gap): Check for size calculation overflow.
12460 * scroll.c (do_line_insertion_deletion_costs): Check for size calc
12461 overflow. Don't bother calling xmalloc when xrealloc will do.
12463 * search.c (Freplace_match): Check for size calculation overflow.
12464 (Fset_match_data): Don't assume list lengths fit in 'int'.
12466 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
12467 for command line length. Do not attempt to address one before the
12468 beginning of an array, as that's not portable.
12470 * term.c (max_frame_lines): Remove; unused.
12471 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
12473 (encode_terminal_code, calculate_costs): Check for size
12474 calculation overflow.
12475 (encode_terminal_code): Use ptrdiff_t, not int, to record glyph
12476 table lengths and related sizes. Don't update size until alloc
12477 done. Redo calculations to avoid overflow.
12478 (calculate_costs): Don't bother calling xmalloc when xrealloc will do.
12480 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
12481 subtracting pointers.
12482 (gobble_line): Check for overflow more carefully. Don't update size
12485 * tparam.c (tparam1): Use ptrdiff_t, not int, for sizes.
12486 Don't update size until alloc done.
12487 Redo size calculations to avoid overflow.

12491 * xdisp.c (store_mode_line_noprop_char, x_consider_frame_title):
12492 Use ptrdiff_t, not int, for sizes.
12493 (store_mode_line_noprop_char): Don't update size until alloc done.
12495 * xfaces.c (lface_id_to_name_size, Finternal_make_lisp_face):
12496 Use ptrdiff_t, not int, for sizes.
12497 (Finternal_make_lisp_face, cache_face):
12498 Check for size calculation overflow.
12499 (cache_face): Treat size calculation overflows as if they were
12500 memory exhaustion (the usual treatment), rather than aborting.
12502 * xfns.c (x_encode_text, x_set_name_internal)
12503 (Fx_change_window_property): Use ptrdiff_t, not int, to count
12504 sizes, since they can exceed INT_MAX in size. Check for size
12505 calculation overflow.
12507 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
12508 (xg_select): Check for size calculation overflow.
12509 Don't update size until alloc done.
12511 * xrdb.c (get_environ_db): Don't assume path length fits in int,
12512 as sprintf is limited to int lengths.
12514 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
12515 (X_LONG_MIN): New macros.
12516 Use them to make the following changes clearer.
12517 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
12518 This change doesn't affect the value now, but it may help remind
12519 future maintainers not to raise the value too much later.
12520 (SELECTION_QUANTUM): Remove, replacing with ...
12521 (selection_quantum): ... new function, which avoids overflow.
12523 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
12524 assumption that selection length fits in 'int'.
12525 (x_reply_selection_request, x_handle_selection_request)
12526 (x_get_window_property, receive_incremental_selection)
12527 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
12528 (lisp_data_to_selection_data, clean_local_selection_data):
12529 Use ptrdiff_t, not int, to record length of selection.
12530 (x_reply_selection_request, x_get_window_property)
12531 (receive_incremental_selection, x_property_data_to_lisp):
12532 Redo calculations to avoid overflow.
12533 (x_reply_selection_request): When sending hint, ceiling it at
12534 X_LONG_MAX rather than relying on wraparound overflow to send
12536 (x_get_window_property, receive_incremental_selection)
12537 (lisp_data_to_selection_data, x_property_data_to_lisp):
12538 Check for size-calculation overflow.
12539 (x_get_window_property, receive_incremental_selection)
12540 (lisp_data_to_selection_data, Fx_register_dnd_atom):
12541 Don't store size until memory allocation succeeds.
12542 (x_get_window_property): Plug memory leak on memory exhaustion.
12543 Don't double-block input; malloc is safe here. Don't assume 2**34
12544 - 4 fits in unsigned long. Add an xassert to check
12545 XGetWindowProperty overflow. Be more careful about overflow
12546 calculations, and distinguish size from memory overflow better.
12547 (receive_incremental_selection): When tracing, don't assume
12548 unsigned int is less than INT_MAX.
12549 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
12550 harmful) conversions of unsigned short to int.
12551 (lisp_data_to_selection_data): Don't assume that integers
12552 in the range -65535 through -1 fit in an X unsigned short.
12553 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
12554 result parameters unless successful. Rely on cons_to_unsigned
12555 to report problems with elements; the old code wasn't right anyway.
12556 (x_check_property_data): Check for int overflow; we cannot use
12557 a wider type due to X limits.

12590 * lisp.h (hash_lookup, hash_put):
12591 * minibuf.c (Ftest_completion):
12592 Use ptrdiff_t for hash table indexes, not int (which is too
12593 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
12594 32-bit --with-wide-int hosts).
12596 * charset.c (Fdefine_charset_internal): Check for integer overflow.
12597 Add a FIXME comment about memory leaks.
12598 (syms_of_charset): Don't assume xmalloc returns.

12605 with outlandish widths.
12606 * character.h (sanitize_tab_width): Rename from sanitize_width,
12607 now that we have two such functions. All uses changed.

12625 * xterm.c: Don't go over XClientMessageEvent limit.
12626 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
12627 (x_send_scroll_bar_event): Likewise. Check that the size does not
12628 exceed limits imposed by XClientMessageEvent, as well as the usual
12629 ptrdiff_t and size_t limits.
12631 * keyboard.c: Overflow, signedness and related fixes.
12632 (make_lispy_movement): Use same integer type in forward decl
12633 that is used in the definition.
12634 (read_key_sequence, keyremap_step):
12635 Change bufsize argument back to int, undoing my 2011-03-30 change.
12636 We prefer signed types, and int is wide enough here.
12637 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
12638 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
12639 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
12640 length, not size_t. Use ptrdiff_t for index, not int.
12641 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
12642 possibility of integer overflow.
12644 Overflow, signedness and related fixes for images.

12668 since parse_image_check makes sure they fit into int.
12669 (png_load, gif_load, svg_load_image):
12670 Prefer int to unsigned where either will do.
12671 (tiff_handler): New function, combining the cores of the
12672 old tiff_error_handler and tiff_warning_handler.
12673 This function is rewritten to use vsnprintf and thereby avoid
12674 stack buffer overflows. It uses only the features of vsnprintf
12675 that are common to both POSIX and native Microsoft.
12676 (tiff_error_handler, tiff_warning_handler): Use it.
12677 (tiff_load, gif_load, imagemagick_load_image):
12678 Don't assume :index value fits in 'int'.
12679 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
12680 (imagemagick_load_image): Check that crop parameters fit into
12681 the integer types that MagickCropImage accepts. Don't assume
12682 Vimagemagick_render_type has a nonnegative value. Don't assume
12683 size_t fits in 'long'.
12684 (gs_load): Use printmax_t to print the widest integers possible.

12698 (handle_single_display_spec): If the display spec is of the form
12699 `(space ...)', and specifies display in the text area, return 2
12701 (try_cursor_movement): Check for the need to scroll more
12702 accurately, and prefer exact match for point under bidi.
12703 Don't advance `row' beyond the last row of the window.

12720 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
12721 buffers, return left-to-right.
12722 (set_cursor_from_row): Consider candidate row a win if its glyph
12723 represents a newline and point is on that newline. Fixes cursor
12724 positioning on the newline at EOL of R2L text within L2R
12725 paragraph, and vice versa.
12726 (try_cursor_movement): Check continued rows, in addition to
12727 continuation rows. Fixes unwarranted scroll when point enters a
12728 continued line of R2L text within an L2R paragraph, or vice versa.
12729 (cursor_row_p): Consider the case of point being equal to
12730 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
12731 from the end of a short line to the beginning of a continued line
12732 of R2L text within L2R paragraph.
12733 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for

12752 extra slot even if the purpose is char-code-property-table.
12754 2011-08-23 Eli Zaretskii <eliz@gnu.org>
12756 * xdisp.c (redisplay_window): When computing centering_position,
12757 account for the height of the header line. (Bug#8874)
12759 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
12760 instead of CHAR_TO_BYTE. Fixes a crash when a completion
12761 candidate is selected by the mouse, and that candidate has a
12762 composed character under the mouse.
12764 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
12765 coordinates reported by pos-visible-in-window-p for a composed
12766 character in column zero.
12768 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>

12772 2011-08-22 Eli Zaretskii <eliz@gnu.org>
12774 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
12775 consider it a hit if to_charpos is anywhere in the range of the
12776 composed buffer positions.
12778 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
12780 * image.c (gif_load): Don't assume that each subimage has the same
12781 dimensions as the base image. Handle disposal method that is
12782 "undefined" by the gif spec (Bug#9335).
12784 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
12786 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

12789 2011-08-19 Eli Zaretskii <eliz@gnu.org>
12791 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
12792 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
12793 from an Org mode buffer to a Speedbar frame.
12795 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
12796 a composition, take its buffer position from IT->cmp_it.charpos.
12797 Fixes cursor positioning at the beginning of a line that begins
12798 with a composed character.
12800 2011-08-18 Eli Zaretskii <eliz@gnu.org>
12802 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
12803 character bidirectional type, use STRONG_L instead. Fixes crashes
12804 in a buffer produced by `describe-categories'.
12806 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
12807 members before the level stack, so they would be saved and
12808 restored when copying iterator state. Fixes incorrect reordering
12809 around TABs covered by display properties.
12811 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
12813 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

12878 * process.c (create_process): Call setup_process_coding_systems
12879 after the pid of the process is set to -1 (Bug#8162).
12881 2011-08-14 Eli Zaretskii <eliz@gnu.org>
12883 * xdisp.c (move_it_in_display_line_to): Don't invoke
12884 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
12885 ppos_it. Fixes vertical cursor motion when line beginning is
12886 covered by an image. (Bug#9296)
12888 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
12890 * nsterm.h (ns_run_ascript): Declare.

12894 (ns_run_ascript): New function.
12895 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
12896 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
12897 the event loop. Get status from as_status (Bug#7276).
12899 * nsterm.m (sendEvent): If event is NSApplicationDefined and
12900 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
12901 the event loop (Bug#7276).
12903 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>

12926 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
12927 (Fnetwork_interface_list): Allocate in increments of bytes instead
12928 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
12929 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
12931 (struct ifflag_def): notrailers is smart on OSX.
12932 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
12933 Get hardware address with getifaddrs if available.
12935 2011-08-12 Eli Zaretskii <eliz@gnu.org>
12937 * xdisp.c (iterate_out_of_display_property): xassert that
12938 IT->position is set to within IT->object's boundaries. Break from
12939 the loop as soon as EOB is reached; avoids infloops in redisplay
12940 when IT->position is set up wrongly due to some bug.
12941 Set IT->current to match the bidi iterator unconditionally.
12942 (push_display_prop): Allow GET_FROM_STRING as IT->method on
12943 entry. Force push_it to save on the stack the current
12944 buffer/string position, to be restored by pop_it. Fix flags in
12945 the iterator structure wrt the object coming from a display
12946 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
12947 properties. (Bug#9284)
12949 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
12951 * fontset.c (fontset_get_font_group): Add proper type checks.

12964 no-display-properties-and-no-overlays under bidi display.
12965 Set disp_pos in the bidi iterator to avoid searches for display
12966 properties and overlays.
12968 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
12970 * editfns.c (Fset_time_zone_rule): Document relationship with the

12976 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
12978 * composite.c (autocmp_chars): Don't reset point. That is done by
12979 restore_point_unwind (Bug#5984).
12981 2011-08-07 Juri Linkov <juri@jurta.org>
12983 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
12984 to show the arg `TIME' instead of `TIMEVAL'.
12986 2011-08-06 Eli Zaretskii <eliz@gnu.org>
12988 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
12989 display property strides EOL and includes a newline, as in
12990 longlines-mode. (Bug#9254)
12991 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
12992 word-wrap under bidirectional display. (Bug#9224)
12994 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
12995 is non-zero, even if the data buffer is NULL. Fixes a crash in
12996 vertical-motion with longlines-mode. (Bug#9254)
12998 2011-08-05 Eli Zaretskii <eliz@gnu.org>
13000 * bidi.c <bidi_cache_total_alloc>: Now static.
13001 (bidi_initialize): Initialize bidi_cache_total_alloc.
13003 * xdisp.c (display_line): Release buffer allocated for shelved bidi
13006 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
13007 amount allocated this far in `bidi_cache_total_alloc'.
13008 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
13009 non-zero, only free the data buffer without restoring the cache
13010 contents. All callers changed.
13012 * dispextern.h (bidi_unshelve_cache): Update prototype.
13014 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
13015 (move_it_in_display_line, move_it_to)
13016 (move_it_vertically_backward, move_it_by_lines): Replace the call
13017 to xfree to an equivalent call to bidi_unshelve_cache.
13018 (move_it_in_display_line_to): Fix logic of returning
13019 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
13021 2011-08-05 Eli Zaretskii <eliz@gnu.org>
13023 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
13024 came from a string character with a `cursor' property. (Bug#9229)
13026 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
13028 * Makefile.in (LIB_PTHREAD): New variable.
13029 (LIBES): Add LIB_PTHREAD (Bug#9216).
13031 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
13032 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
13034 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
13036 * regex.c (re_iswctype): Remove some redundant boolean conversions.
13038 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
13040 * xterm.c (x_find_topmost_parent): New function.
13041 (x_set_frame_alpha): Find topmost parent window with
13042 x_find_topmost_parent and set the property there also (bug#9181).
13043 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
13045 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
13047 * callproc.c (Fcall_process): Avoid vfork clobbering
13048 the local vars buffer, coding_systems, current_dir.
13050 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
13052 * keymap.c (Fmake_composed_keymap): Move to subr.el.
13054 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
13056 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
13057 so that it is not optimized away.
13059 * xdisp.c (compute_display_string_pos): Remove unused local.
13061 2011-08-02 Eli Zaretskii <eliz@gnu.org>
13063 Fix slow cursor motion and scrolling in large buffers with
13064 selective display, like Org Mode buffers. (Bug#9218)
13066 * dispextern.h (struct bidi_it): New member disp_prop_p.
13068 * xdisp.c: Remove one-slot cache of display string positions.
13069 (compute_display_string_pos): Accept an additional argument
13070 DISP_PROP_P; callers changed. Scan at most 5K characters forward
13071 for a display string or property. If found, set DISP_PROP_P
13074 * bidi.c (bidi_fetch_char): Accept an additional argument
13075 DISP_PROP_P, and pass it to compute_display_string_pos.
13076 Only handle text covered by a display string if DISP_PROP_P is returned
13077 non-zero. All callers of bidi_fetch_char changed.
13079 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
13081 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
13083 2010-12-03 Don March <don@ohspite.net>
13085 * keymap.c (Fdefine_key): Fix non-prefix key error message when
13086 last character M-[char] is translated to ESC [char] (bug#7541).
13088 2011-08-02 Kenichi Handa <handa@m17n.org>
13090 * lisp.h (uniprop_table): Extern it.
13092 * chartab.c (uniprop_table): Make it non-static.
13094 2011-08-01 Eli Zaretskii <eliz@gnu.org>
13096 * xdisp.c (forward_to_next_line_start): Accept additional argument
13097 BIDI_IT_PREV, and store into it the state of the bidi iterator had
13099 (reseat_at_next_visible_line_start): Use the bidi iterator state
13100 returned by forward_to_next_line_start to restore the state of
13101 it->bidi_it after backing up to previous newline. (Bug#9212)
13103 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
13105 * regex.c (re_comp): Protoize.
13106 (re_exec): Fix return type.
13107 (regexec): Fix type of `ret'. (Bug#9203)
13109 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
13111 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
13112 This is needed if max-image-size is a floating-point number.
13114 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
13116 * print.c (print_object): Print empty symbol as ##.
13118 * lread.c (read1): Read ## as empty symbol.
13120 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
13122 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
13123 setting frame foreground color (Bug#9175).
13124 (x_set_background_color): Likewise.
13126 * nsmenu.m (-setText): Size tooltip dimensions precisely to
13127 contents (Bug#9176).
13128 (EmacsTooltip -init): Remove bezels and add shadows to
13131 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
13132 or scroll bar (Bug#8470).
13134 * nsfont.m (nsfont_open): Remove assignment to voffset and
13135 unnecessary vars hshink, expand, hd, full_height, min_height.
13136 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
13138 * nsterm.h (nsfont_info): Remove voffset field.
13140 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
13142 Implement strike-through and overline on NextStep (Bug#8863).
13144 * nsfont.m (nsfont_open): Use underline position provided by font,
13145 instead of hard-coded value of 2.
13146 (nsfont_draw): Call ns_draw_text_decoration instead.
13148 * nsterm.h: Add declaration for ns_draw_text_decoration.
13150 * nsterm.m (ns_draw_text_decoration): New function for drawing
13151 underline, overline, and strike-through.
13152 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
13153 ns_draw_text_decoration. Change treatment of cursor drawing to
13154 accommodate underlining, etc.
13156 2011-07-28 Eli Zaretskii <eliz@gnu.org>
13158 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
13161 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
13163 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
13164 Without this fix, if a signal arrives just after memory fills up,
13165 'malloc' might be invoked reentrantly.
13167 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
13168 In other words, assume that every image size is allowed, on non-X
13169 hosts. This assumption is probably wrong, but it lets Emacs compile.
13171 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
13173 * regex.c (re_iswctype): Convert return values to boolean.
13175 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
13177 * xdisp.c (compute_display_string_pos): Don't use cached display
13178 string position if the buffer had its restriction changed.
13181 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
13183 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
13185 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
13187 Integer signedness and overflow and related fixes. (Bug#9079)
13189 * bidi.c: Integer size and overflow fixes.
13190 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
13191 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
13192 (bidi_cache_find_level_change, bidi_cache_ensure_space)
13193 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
13194 (bidi_find_other_level_edge):
13195 Use ptrdiff_t instead of EMACS_INT where either will do.
13196 This works better on 32-bit hosts configured --with-wide-int.
13197 (bidi_cache_ensure_space): Check for size-calculation overflow.
13198 Use % rather than repeated addition, for better worst-case speed.
13199 Don't set bidi_cache_size until after xrealloc returns, because it
13201 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
13202 (bidi_cache_ensure_space): Also check that the bidi cache size
13203 does not exceed that of the largest Lisp string or buffer. See Eli
13204 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
13206 * alloc.c (__malloc_size_t): Remove.
13207 All uses replaced by size_t. See Andreas Schwab's note
13208 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
13210 * image.c: Improve checking for integer overflow.
13211 (check_image_size): Assume that f is nonnull, since
13212 it is always nonnull in practice. This is one less thing to
13213 worry about when checking for integer overflow later.
13214 (x_check_image_size): New function, which checks for integer
13215 overflow issues inside X.
13216 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
13217 This removes the need for a memory_full check.
13218 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
13219 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
13220 (xbm_read_bitmap_data): Change locals back to 'int', since
13221 their values must fit in 'int'.
13222 (xpm_load_image, png_load, tiff_load):
13223 Invoke x_create_x_image_and_pixmap earlier,
13224 to avoid much needless work if the image is too large.
13225 (tiff_load): Treat overly large images as if
13226 x_create_x_image_and_pixmap failed, not as malloc failures.
13227 (gs_load): Use x_check_image_size.
13229 * gtkutil.c: Omit integer casts.
13230 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
13231 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
13233 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
13235 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
13236 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
13237 would wrongly return t on a 64-bit host.
13239 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
13240 The plain *_OVERFLOW macros run afoul of GCC bug 49705
13241 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
13242 and therefore cause GCC to emit a bogus diagnostic in some cases.
13244 * image.c: Integer signedness and overflow and related fixes.
13245 This is not an exhaustive set of fixes, but it's time to
13246 record what I've got.
13247 (lookup_pixel_color, check_image_size): Remove redundant decls.
13248 (check_image_size): Don't assume that arbitrary EMACS_INT values
13249 fit in 'int', or that arbitrary 'double' values fit in 'int'.
13250 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
13251 (tiff_load, imagemagick_load_image):
13252 Check for overflow in size calculations.
13253 (x_create_x_image_and_pixmap): Remove unnecessary test for
13254 xmalloc returning NULL; that can't happen.
13255 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
13256 (xpm_color_bucket): Use better integer hashing function.
13257 (xpm_cache_color): Don't possibly over-allocate memory.
13258 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
13259 (gif_memory_source):
13260 Use ptrdiff_t, not int or size_t, to record sizes.
13261 (png_load): Don't assume values greater than 2**31 fit in 'int'.
13262 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
13263 either works, as we prefer signed integers.
13264 (tiff_read_from_memory, tiff_write_from_memory):
13265 Return tsize_t, not size_t, since that's what the TIFF API wants.
13266 (tiff_read_from_memory): Don't fail simply because the read would
13267 go past EOF; instead, return a short read.
13268 (tiff_load): Omit no-longer-needed casts.
13269 (Fimagemagick_types): Don't assume size fits into 'int'.
13271 Improve hashing quality when configured --with-wide-int.
13272 * fns.c (hash_string): New function, taken from sxhash_string.
13273 Do not discard information about ASCII character case; this
13274 discarding is no longer needed.
13275 (sxhash-string): Use it. Change sig to match it. Caller changed.
13276 * lisp.h: Declare it.
13277 * lread.c (hash_string): Remove, since we now use fns.c's version.
13278 The fns.c version returns a wider integer if --with-wide-int is
13279 specified, so this should help the quality of the hashing a bit.
13281 * emacs.c: Integer overflow minor fix.
13282 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
13283 Define only if GNU_LINUX.
13284 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
13286 * dispnew.c: Integer signedness and overflow fixes.
13287 Remove unnecessary forward decls, that were a maintenance hassle.
13288 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
13290 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
13291 (scrolling_window): Use ptrdiff_t, not int, for byte count.
13292 (prepare_desired_row, line_draw_cost):
13293 Use int, not unsigned, where either works.
13294 (save_current_matrix, restore_current_matrix):
13295 Use ptrdiff_t, not size_t, where either works.
13296 (init_display): Check for overflow more accurately, and without
13297 relying on undefined behavior.
13299 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
13300 Remove, replacing with the new symbols in lisp.h. All uses changed.
13301 * fileio.c (make_temp_name):
13302 * filelock.c (lock_file_1, lock_file):
13303 * xdisp.c (message_dolog):
13304 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
13305 Use pMd etc. instead.
13306 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
13307 replacing the pWIDE etc. symbols removed from editfns.c.
13309 * keyboard.h (num_input_events): Now uintmax_t.
13310 This is (very slightly) less likely to mess up due to wraparound.
13313 * buffer.c: Integer signedness fixes.
13314 (alloc_buffer_text, enlarge_buffer_text):
13315 Use ptrdiff_t rather than size_t when either will do, as we prefer
13318 * alloc.c: Integer signedness and overflow fixes.
13319 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
13320 (__malloc_size_t): Default to size_t, not to int.
13321 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
13322 (Fgarbage_collect, mark_object_loop_halt, mark_object):
13323 Prefer ptrdiff_t to size_t when either would do, as we prefer
13325 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
13326 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
13327 Now const. Initialize with values that are in range even if char
13329 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
13330 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
13331 These functions do the right thing with sizes > 2**32.
13332 (check_depth): Now ptrdiff_t, not int.
13333 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
13334 Adjust to new way of storing sizes. Check for size overflow bugs
13336 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
13337 slightly wrong anyway, as it missed one instance of
13338 XMALLOC_OVERRUN_CHECK_OVERHEAD.
13339 (refill_memory_reserve): Omit needless cast to size_t.
13340 (mark_object_loop_halt): Mark as externally visible.
13342 * xselect.c: Integer signedness and overflow fixes.
13343 (Fx_register_dnd_atom, x_handle_dnd_message):
13344 Use ptrdiff_t, not size_t, since we prefer signed.
13345 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
13346 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
13347 x_dnd_atoms_size and x_dnd_atoms_length.
13349 * doprnt.c: Prefer signed to unsigned when either works.
13351 * doprnt.c (doprnt):
13353 * xdisp.c (vmessage):
13354 Use ptrdiff_t, not size_t, when using or implementing doprnt,
13355 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
13356 prefer signed arithmetic to avoid comparison confusion.
13357 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
13358 but is a bit tricky.
13360 Assume freestanding C89 headers, string.h, stdlib.h.
13361 * data.c, doprnt.c, floatfns.c, print.c:
13362 Include float.h unconditionally.
13363 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
13364 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
13365 * regex.c: Likewise for stddef.h, string.h.
13366 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
13367 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
13368 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
13369 (STDC_HEADERS): Remove obsolete defines.
13370 * sysdep.c: Include limits.h unconditionally.
13372 Assume support for memcmp, memcpy, memmove, memset.
13373 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
13374 * regex.c (memcmp, memcpy):
13375 Remove; we assume C89 now.
13377 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
13378 (__malloc_safe_bcopy): Remove; no longer needed.
13380 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
13381 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
13382 well either way, and we prefer signed to unsigned.
13384 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
13386 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
13387 closes the connection while we're reading (bug#9182).
13389 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
13391 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
13392 are specified (Bug#9168).
13394 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
13396 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
13397 Found by GCC static checking and --with-wide-int on a 32-bit host.
13399 2011-07-25 Eli Zaretskii <eliz@gnu.org>
13401 * xdisp.c (compute_display_string_pos): Fix logic of caching
13402 previous display string position. Initialize cached_prev_pos to
13403 -1. Fixes slow-down at the beginning of a buffer.
13405 2011-07-24 Eli Zaretskii <eliz@gnu.org>
13407 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
13408 for attrs[LFACE_FONTSET_INDEX].
13410 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
13412 * xml.c (parse_region): Remove unused local
13413 that was recently introduced.
13415 2011-07-23 Eli Zaretskii <eliz@gnu.org>
13417 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
13418 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
13420 * xdisp.c (move_it_in_display_line_to): Record the best matching
13421 position for TO_CHARPOS while scanning the line, and restore it on
13422 exit if none of the characters scanned was an exact match.
13423 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
13424 when exact match is impossible due to invisible text, and the
13425 lines are truncated.
13427 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
13429 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
13432 2011-07-22 Eli Zaretskii <eliz@gnu.org>
13434 Fix a significant slow-down of cursor motion with C-n, C-p,
13435 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
13436 auto-repeat under bidi redisplay in fontified buffers.
13437 * xdisp.c (compute_stop_pos_backwards): New function.
13438 (next_element_from_buffer): Call compute_stop_pos_backwards to
13439 find a suitable prev_stop when we find ourselves before
13441 (reseat): Don't look for prev_stop, as that could mean a very long
13443 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
13444 <cached_disp_overlay_modiff>: Cache for last found display string
13446 (compute_display_string_pos): Return the cached position if asked
13447 about the same buffer in the same area of character positions, and
13448 the buffer wasn't changed since the time the display string
13449 position was cached.
13451 2011-07-22 Eli Zaretskii <eliz@gnu.org>
13453 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
13454 is an integer, which is important for empty lines. (Bug#9149)
13456 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
13458 * frame.c (Fmodify_frame_parameters): In tty case, update the
13459 default face if necessary (Bug#4238).
13461 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
13463 * editfns.c (Fstring_to_char): No need to explain what a character
13464 is in the docstring (Bug#6576).
13466 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
13468 * xml.c (parse_region): Make sure we always return a tree.
13470 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
13472 * xml.c (parse_region): If a document contains only comments,
13475 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
13477 * xml.c (make_dom): Return comments, too.

13482 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
13483 and the surrounding thread.
13484 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
13485 rather than fgets, and retry after EINTR. Otherwise, 'emacs
13486 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
13488 * s/openbsd.h (BROKEN_SIGIO): Define.
13489 * unexelf.c (unexec) [__OpenBSD__]:
13490 Don't update the .mdebug section of the Alpha COFF symbol table.
13492 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
13494 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
13497 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
13499 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
13500 This fixes some race conditions on the permissions of any newly
13503 * alloc.c (valid_pointer_p): Use pipe, not open.
13504 This fixes some permissions issues when debugging.
13506 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
13507 If fchown fails to set both uid and gid, try to set just gid,
13508 as that is sometimes allowed. Adjust the file's mode to eliminate
13509 setuid or setgid bits that are inappropriate if fchown fails.
13511 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
13513 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
13514 to compare Lisp_Objects.

13519 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
13521 * lread.c (read_integer): Unread even EOF character.
13522 (read1): Likewise. Properly record start position of symbol.

13525 symbol character follows.
13527 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
13529 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
13530 This works around a problem with the previous change to Fcopy_file.
13531 Recent glibc declares fchown with __attribute__((warn_unused_result)),
13532 and without this change, GCC might complain about discarding
13533 fchown's return value.
13535 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
13537 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
13539 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
13541 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
13543 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
13545 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
13546 it's used from the C level.
13548 * process.c: Use the same condition for POLL_FOR_INPUT in both
13549 keyboard.c and process.c (bug#1858).
13551 2011-07-09 Lawrence Mitchell <wence@gmx.li>
13553 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
13554 (Fgnutls_boot): Use it.
13556 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
13558 * doc.c (Fsubstitute_command_keys): Revert last change.
13560 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
13562 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
13563 quotes the next character, and doesn't affect other longer
13564 sequences (bug#8935).
13566 * lread.c (syms_of_lread): Clarify that is isn't only
13567 `eval-buffer' and `eval-defun' that's affected by
13568 `lexical-binding' (bug#8460).
13570 2011-07-15 Eli Zaretskii <eliz@gnu.org>
13572 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
13573 bidi redisplay when a line includes both an image and is truncated.
13575 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
13577 Fix minor problems found by static checking.
13578 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
13579 (elsz): Now a signed constant, not a size_t var. We prefer signed
13580 types to unsigned, to avoid integer comparison confusion. Without
13581 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
13582 "cannot optimize loop, the loop counter may overflow", a symptom
13584 * indent.c (Fvertical_motion): Mark locals as initialized.
13585 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
13587 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>

13613 (display_string): If we need to ignore text properties of
13614 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
13615 original value of -1 will not work with bidi.)
13616 (compute_display_string_pos): First arg is now struct
13617 `text_pos *'; all callers changed. Support display properties on
13619 (compute_display_string_end): Support display properties on Lisp
13621 (init_iterator, reseat_1, reseat_to_string): Initialize the
13622 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
13623 when iterating on a string not from display properties).
13624 (compute_display_string_pos, compute_display_string_end):
13625 Fix calculation of the object to scan. Fixes an error when using
13627 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
13628 base_level_stop; instead, set base_level_stop to BEGV.
13629 Fixes crashes in vertical-motion.
13630 (next_element_from_buffer): Improve commentary for when
13631 the iterator is before prev_stop.
13632 (init_iterator): Initialize bidi_p from the default value of
13633 bidi-display-reordering, not from buffer-local value. Use the
13634 buffer-local value only if initializing for buffer iteration.

13655 parts of next_element_from_buffer, next_element_from_string, and
13656 next_element_from_c_string.
13657 (tool_bar_lines_needed, redisplay_tool_bar)
13658 (display_menu_bar): Force left-to-right direction. Add a FIXME
13659 comment for making that be controlled by a user option.

13668 (get_overlay_strings_1, push_display_prop): Set up the bidi
13669 iterator for displaying display or overlay strings.
13670 (forward_to_next_line_start): Don't use the shortcut if
13672 (back_to_previous_visible_line_start): If handle_display_prop
13673 pushed the iterator stack, restore the internal state of the bidi
13674 iterator by calling bidi_pop_it same number of times.
13675 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
13676 and we are bidi-iterating, don't decrement the iterator position;
13677 instead, set the first_elt flag in the bidi iterator, to produce
13679 (reseat_1): Remove redundant setting of string_from_display_prop_p.
13680 (push_display_prop): xassert that we are iterating a buffer.
13681 (push_it, pop_it): Save and restore paragraph_embedding member.
13682 (handle_single_display_spec, next_overlay_string)
13683 (get_overlay_strings_1, reseat_1, reseat_to_string)
13684 (push_display_prop): Set up the `unibyte' member of bidi_it.string
13685 correctly. Don't assume unibyte strings are not bidi-reordered.

13693 popping after iteration over a string that came from a display
13694 property. Fix a typo in popping stretch info. Add an assertion
13695 for verifying that the iterator position is in sync with the bidi
13697 (handle_single_display_spec, get_overlay_strings_1)
13698 (push_display_prop): Fix initialization of paragraph direction for
13699 string when that of the parent object is not yet determined.

13711 (try_scrolling, redisplay_window, display_line): Use them when
13712 saving a temporary copy of the iterator and restoring it back.
13713 (back_to_previous_visible_line_start, reseat_1)

13722 displayed in margins. (Bug#8133) (Bug#8867)
13723 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past

13751 changed to -1 and -2, respectively.
13752 (bidi_char_at_pos): New function.
13753 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak):

13786 (bidi_push_it, bidi_pop_it): Add prototypes.
13787 (struct iterator_stack_entry): New members bidi_p,
13788 paragraph_embedding, and from_disp_prop_p.

13836 Pass Qx_lost_selection_functions rather than
13837 Vx_lost_selection_functions to Frun_hook_with_args.
13839 2011-07-13 Paul Eggert <eggert@cs.ucla.edu>
13841 * buffer.c (Fget_buffer_create): Initialize inhibit_shrinking.
13842 The old code sometimes used this field without initializing it.
13844 * alloc.c (gc_sweep): Don't read past end of array.
13845 In theory, the old code could also have corrupted Emacs internals,
13846 though it'd be very unlikely.

13850 * character.c (Fcharacterp): Don't advertise optional ignored
13851 argument. (Bug#4026)

14109 (clone_per_buffer_values): Don't assume that

14111 This isn't true in general, and it's particularly not true
14112 if Emacs is configured with --with-wide-int.
14113 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
14114 New macros, used in the buffer.c change.

14150 Random fixes. E.g., (random) never returned negative values.
14151 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
14152 subseconds part to the entropy, as that's a bit more random.
14153 Prefer signed to unsigned, since the signedness doesn't matter and
14154 in general we prefer signed. When given a limit, use a
14155 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
14156 latter isn't right if USE_2_TAGS_FOR_INTS.
14157 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
14158 not 0..VALMASK. Don't discard "excess" bits that random () returns.
14160 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
14162 * textprop.c (text_property_stickiness):
14163 Obey Vtext_property_default_nonsticky.

14170 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
14171 This is more efficient than Ffile_directory_p and avoids a minor race.
14173 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
14175 * buffer.c (Foverlay_put): Say what the return value is
14178 * fileio.c (barf_or_query_if_file_exists): Check first if the file
14179 is a directory before asking whether to use the file name
14181 (barf_or_query_if_file_exists): Make the "File is a directory"
14182 error be more correct.
14184 * fns.c (Frequire): Remove the mention of the .gz files, since
14185 that's installation-specific, but keep the mention of
14186 `get-load-suffixes'.
14188 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
14190 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

14196 (syms_of_gnutls): Remove duplicate DEFSYM for
14197 Qgnutls_bootprop_verify_hostname_error, an error for
14198 Qgnutls_bootprop_verify_error (which is no longer used).
14200 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
14201 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
14202 Also (re)move comments that are misplaced or no longer relevant.

14227 leave any prefix arg for the up event (Bug#1586).
14229 2011-07-02 Lars Magne Ingebrigtsen <larsi@gnus.org>
14231 * lread.c (syms_of_lread): Mention single symbols defined by
14232 `defvar' or `defconst' (bug#7154).
14234 * fns.c (Frequire): Mention .el.gz files (bug#7314).
14235 (Frequire): Mention get-load-suffixes.

14265 (syms_of_keymap): Defsubr make-composed-keymap.
14266 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

14295 (xgselect_initialize): Ditto.
14297 * process.c: Add defined (HAVE_GSETTINGS) for xgselect.h

14303 * eval.c (struct backtrace): Simplify and port the data structure.
14304 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
14305 signed bit field, as this assumption is not portable and it makes
14306 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
14307 "char debug_on_exit : 1" as this is not portable either; instead,
14308 use the portable "unsigned int debug_on_exit : 1". Remove unused
14309 member evalargs. Remove obsolete comments about cc bombing out.
14311 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

14405 Use gnulib's dup2 module instead of rolling our own.
14406 * sysdep.c (dup2) [!HAVE_DUP2]: Remove; gnulib now does this.
14408 2011-06-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14410 * dispnew.c (scrolling_window): Before scrolling, turn off a

14477 * print.c (printchar, strout): Check for string overflow.
14478 (PRINTPREPARE, printchar, strout):
14479 Don't set size unless allocation succeeds.
14481 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
14482 for sizes. Check for string overflow more accurately.
14483 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
14485 * macros.c: Integer and buffer overflow fixes.
14486 * keyboard.h (struct keyboard.kbd_macro_bufsize):
14487 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

14491 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
14493 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
14495 * lread.c: Integer overflow fixes.
14496 (read_integer): Radix is now EMACS_INT, not int,
14497 to improve quality of diagnostics for out-of-range radices.
14498 Calculate buffer size correctly for out-of-range radices.
14499 (read1): Check for integer overflow in radices, and in
14500 read-circle numbers.
14501 (read_escape): Avoid int overflow.
14502 (Fload, openp, read_buffer_size, read1)
14503 (substitute_object_recurse, read_vector, read_list, map_obarray):
14504 Use ptrdiff_t, not int, for sizes.

14519 2011-06-22 Leo Liu <sdl.web@gmail.com>
14521 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
14522 Move to minibuffer.el.
14524 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
14526 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
14527 The following patches are for when GLYPH_DEBUG && !XASSERT.
14528 * dispextern.h (trace_redisplay_p, dump_glyph_string):
14529 * dispnew.c (flush_stdout):
14530 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
14531 Mark as externally visible.
14532 * dispnew.c (check_window_matrix_pointers): Now static.
14533 * dispnew.c (window_to_frame_vpos):
14534 * xfns.c (unwind_create_frame):
14535 * xterm.c (x_check_font): Remove unused local.
14536 * scroll.c (CHECK_BOUNDS):
14537 * xfaces.c (cache_fache): Rename local to avoid shadowing.
14538 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
14539 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
14540 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
14541 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
14543 (debug_method_add): Use va_list and vsprintf rather than relying
14544 on undefined behavior with wrong number of arguments.
14545 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
14546 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
14547 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
14548 since we're not interested in debugging glyphs with old libraries.
14549 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
14550 GCC 4.6.0's static checking.
14552 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
14554 Integer overflow and signedness fixes (Bug#8873).

14570 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
14571 (.bitmaps_last, struct x_output.icon_bitmap):
14572 Use ptrdiff_t, not int, for bitmap indexes.
14573 (x_allocate_bitmap_record): Check for size overflow.
14574 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
14576 Use ptrdiff_t, not int, for overlay counts.
14577 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
14578 * editfns.c (overlays_around, get_pos_property):
14579 * textprop.c (get_char_property_and_overlay):
14580 * xdisp.c (next_overlay_change, note_mouse_highlight):
14581 * xfaces.c (face_at_buffer_position):
14582 * buffer.c (OVERLAY_COUNT_MAX): New macro.
14583 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
14584 (Fnext_overlay_change, Fprevious_overlay_change)
14585 (mouse_face_overlay_overlaps, Foverlays_in):
14586 Use ptrdiff_t, not int, for sizes.
14587 (overlays_at, overlays_in): Check for size-calculation overflow.
14589 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
14591 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
14592 (x_session_initialize): Do not assume string length fits in int.
14594 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
14595 This is unlikely, but can occur if DPI is outlandish.
14597 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
14598 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
14600 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
14601 * xrdb.c (magic_file_p, search_magic_path):
14602 Omit last arg SUFFIX; it was always 0. All callers changed.
14603 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
14605 * xfont.c (xfont_match): Avoid need for strlen.
14607 * xfns.c: Don't assume strlen fits in int.

14610 * xdisp.c (message_log_check_duplicate): Return intmax_t,
14611 not unsigned long, as we prefer signed integers. All callers changed.
14612 Detect integer overflow in repeat count.
14613 (message_dolog): Don't assume print length fits in 39 bytes.
14614 (display_mode_element): Don't assume strlen fits in int.
14616 * termcap.c: Don't assume sizes fit in int and never overflow.
14617 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
14618 (gobble_line): Check for size-calculation overflow.
14620 * minibuf.c (Fread_buffer):
14621 * lread.c (intern, intern_c_string):
14622 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:

14635 * filelock.c: Fix some buffer overrun and integer overflow issues.
14636 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
14637 Reformulate so as not to need the command string.
14638 Invoke gzip -cd rather than gunzip, as it's more portable.
14639 (lock_info_type, lock_file_1, lock_file):
14640 Don't assume pid_t and time_t fit in unsigned long.
14641 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
14642 (current_lock_owner): Prefer signed type for sizes.
14643 Use memcpy, not strncpy, where memcpy is what is really wanted.
14644 Don't assume (via atoi) that time_t and pid_t fit in int.
14645 Check for time_t and/or pid_t out of range, e.g., via a network share.
14646 Don't alloca where an auto var works fine.
14648 * fileio.c: Fix some integer overflow issues.
14649 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
14650 Don't assume string length fits in int.
14651 (directory_file_name): Don't assume string length fits in long.
14652 (make_temp_name): Don't assume pid fits in int, or that its print
14653 length is less than 20.
14655 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
14657 * coding.c (make_subsidiaries): Don't assume string length fits in int.
14659 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
14661 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.

14665 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
14666 (main): Don't invoke strlen when not needed.

14672 (Fgetenv_internal):
14673 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
14675 * lread.c (invalid_syntax): Omit length argument.
14676 All uses changed. This doesn't fix a bug, but it simplifies the
14677 code away from its former Hollerith-constant appearance, and it's
14678 one less 'int' to worry about when looking at integer-overflow issues.
14679 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
14681 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
14682 This didn't break anything, but it didn't help either.
14683 It's confusing to put a bogus integer in a place where the actual
14684 value does not matter.
14685 (LIST_END_P): Remove unused macro and its bogus comment.
14686 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
14688 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
14689 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
14691 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
14692 We prefer signed types, and the value cannot exceed the EMACS_INT
14693 range anyway (because otherwise the length would not be representable).
14694 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
14695 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
14696 This avoids a GCC warning when WIDE_EMACS_INT.
14698 * indent.c (sane_tab_width): New function.
14699 (current_column, scan_for_column, Findent_to, position_indentation)
14700 (compute_motion): Use it. This is just for clarity.
14701 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
14703 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
14705 * lisp.h (lint_assume): New macro.
14706 * composite.c (composition_gstring_put_cache):
14707 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
14709 * editfns.c, insdel.c:
14710 Omit unnecessary forward decls, to simplify future changes.
14712 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
14714 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
14716 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
14717 Use much-faster test for byte-length change.
14718 Don't assume string byte-length fits in 'int'.
14719 Check that character arg fits in 'int'.
14720 (mapcar1): Declare byte as byte, for clarity.
14722 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
14724 * fns.c (concat): Catch string overflow earlier.
14725 Do not rely on integer wraparound.
14727 * dispextern.h (struct it.overlay_strings_charpos)
14728 (struct it.selective): Now EMACS_INT, not int.
14729 * xdisp.c (forward_to_next_line_start)
14730 (back_to_previous_visible_line_start)
14731 (reseat_at_next_visible_line_start, next_element_from_buffer):
14732 Don't arbitrarily truncate the value of 'selective' to int.
14734 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
14736 * composite.c: Don't truncate sizes to 'int'.
14737 (composition_gstring_p, composition_reseat_it)
14738 (composition_adjust_point): Use EMACS_INT, not int.
14739 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
14740 not EMACS_UINT, for indexes.
14742 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
14744 * buffer.c: Include <verify.h>.
14745 (struct sortvec.priority, struct sortstr.priority):
14746 Now EMACS_INT, not int.
14747 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
14748 (struct sortstr.size, record_overlay_string)
14749 (struct sortstrlist.size, struct sortlist.used):
14750 Don't truncate size to int.
14751 (record_overlay_string): Check for size-calculation overflow.
14752 (init_buffer_once): Check at compile-time, not run-time.
14754 2011-06-22 Jim Meyering <meyering@redhat.com>
14756 Don't leak an XBM-image-sized buffer
14757 * image.c (xbm_load): Free the image buffer after using it.
14759 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
14762 * composite.c (find_automatic_composition): Omit needless 'return 0;'
14763 that Sun C diagnosed.
14764 * fns.c (secure_hash): Fix pointer signedness issue.
14765 * intervals.c (static_offset_intervals): New function.
14766 (offset_intervals): Use it.
14768 2011-06-21 Leo Liu <sdl.web@gmail.com>
14771 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
14774 * fns.c (secure_hash): Rename from crypto_hash_function and change
14775 the first arg to accept symbols.
14776 (Fsecure_hash): New primitive.
14777 (syms_of_fns): New symbols.
14779 2011-06-20 Deniz Dogan <deniz@dogan.se>
14781 * process.c (Fset_process_buffer): Clarify return value in
14784 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
14786 * dispnew.c (add_window_display_history): Use BVAR.
14788 * xdisp.c (debug_method_add): Use BVAR.
14789 (check_window_end, dump_glyph_matrix, dump_glyph)
14790 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
14792 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
14795 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
14796 check till after the cache is created in init_frame_faces.
14798 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
14800 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
14802 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
14804 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
14805 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
14806 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
14808 Improve buffer-overflow checking (Bug#8873).
14809 * fileio.c (Finsert_file_contents):
14810 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
14811 Remove the old (too-loose) buffer overflow checks.
14812 They weren't needed, since make_gap checks for buffer overflow.
14813 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
14814 The old code merely checked for Emacs fixnum overflow, and relied
14815 on undefined (wraparound) behavior. The new code avoids undefined
14816 behavior, and also checks for ptrdiff_t and/or size_t overflow.
14818 * editfns.c (Finsert_char): Don't dump core with very negative counts.
14819 Tune. Don't use wider integers than needed. Don't use alloca.
14820 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
14822 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
14824 * insdel.c, lisp.h (buffer_overflow): New function.
14825 (insert_from_buffer_1, replace_range, replace_range_2):
14826 * insdel.c (make_gap_larger):
14827 * editfns.c (Finsert_char):
14828 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
14830 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
14832 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
14834 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
14836 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
14837 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
14839 * fileio.c: Don't assume EMACS_INT fits in off_t.
14840 (emacs_lseek): New static function.
14841 (Finsert_file_contents, Fwrite_region): Use it.
14842 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
14844 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
14846 * fns.c: Don't overflow int when computing a list length.
14847 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
14848 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
14849 truncation on 64-bit hosts. Check for QUIT every
14850 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
14851 faster and is responsive enough.
14852 (Flength): Report an error instead of overflowing an integer.
14853 (Fsafe_length): Return a float if the value is not representable
14854 as a fixnum. This shouldn't happen except in contrived situations.
14855 (Fnthcdr, Fsort): Don't assume list length fits in int.
14856 (Fcopy_sequence): Don't assume vector length fits in int.
14858 * alloc.c: Check that resized vectors' lengths fit in fixnums.
14859 (header_size, word_size): New constants.
14860 (allocate_vectorlike): Don't check size overflow here.
14861 (allocate_vector): Check it here instead, since this is the only
14862 caller of allocate_vectorlike that could cause overflow.
14863 Check that the new vector's length is representable as a fixnum.
14865 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
14866 The previous code was bogus. For example, next_almost_prime (32)
14867 returned 39, which is undesirable as it is a multiple of 3; and
14868 next_almost_prime (24) returned 25, which is a multiple of 5 so
14869 why was the code bothering to check for multiples of 7?
14871 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
14873 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
14875 Variadic C functions now count arguments with ptrdiff_t.
14876 This partly undoes my 2011-03-30 change, which replaced int with size_t.
14877 Back then I didn't know that the Emacs coding style prefers signed int.
14878 Also, in the meantime I found a few more instances where arguments
14879 were being counted with int, which may truncate counts on 64-bit
14880 machines, or EMACS_INT, which may be unnecessarily wide.
14881 * lisp.h (struct Lisp_Subr.function.aMANY)
14882 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
14883 Arg counts are now ptrdiff_t, not size_t.
14884 All variadic functions and their callers changed accordingly.
14885 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
14886 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
14887 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
14888 * callint.c (Fcall_interactively): Check arg count for overflow,
14889 to avoid potential buffer overrun. Use signed char, not 'int',
14890 for 'varies' array, so that we needn't bother to check its size
14891 calculation for overflow.
14892 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
14893 * eval.c (apply_lambda):
14894 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
14895 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
14896 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
14898 * callint.c (Fcall_interactively): Don't use index var as event count.
14900 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
14901 * mem-limits.h (SIZE): Remove; no longer used.
14903 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
14905 Remove unnecessary casts.
14906 * xterm.c (x_term_init):
14907 * xfns.c (x_set_border_pixel):
14908 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
14909 These aren't needed now that we assume ANSI C.
14911 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
14912 It's more likely to cause problems (due to unsigned overflow)
14915 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
14917 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
14919 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
14921 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
14923 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
14925 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
14927 GLYPH_CODE_FACE returns EMACS_INT, not int.
14928 * dispextern.h (merge_faces):
14929 * xfaces.c (merge_faces):
14930 * xdisp.c (get_next_display_element, next_element_from_display_vector):
14931 Don't assume EMACS_INT fits in int.
14933 * character.h (CHAR_VALID_P): Remove unused parameter.
14934 * fontset.c, lisp.h, xdisp.c: All uses changed.
14936 * editfns.c (Ftranslate_region_internal): Omit redundant test.
14938 * fns.c (concat): Minor tuning based on overflow analysis.
14939 This doesn't fix any bugs. Use int to hold character, instead
14940 of constantly refetching from Emacs object. Use XFASTINT, not
14941 XINT, for value known to be a character. Don't bother comparing
14942 a single byte to 0400, as it's always less.
14944 * floatfns.c (Fexpt):
14945 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
14947 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
14950 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
14952 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
14953 Without this fix, on a 64-bit host (aset S 0 4294967386) would
14954 incorrectly succeed when S was a string, because 4294967386 was
14955 truncated before it was used.
14957 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
14958 Otherwise, an out-of-range integer could cause undefined behavior
14961 * composite.c: Use int, not EMACS_INT, for characters.
14962 (fill_gstring_body, composition_compute_stop_pos): Use int, not
14963 EMACS_INT, for values that are known to be in character range.
14964 This doesn't fix any bugs but is the usual style inside Emacs and
14965 may generate better code on 32-bit machines.
14967 Make sure a 64-bit char is never passed to ENCODE_CHAR.
14968 This is for reasons similar to the recent CHAR_STRING fix.
14969 * charset.c (Fencode_char): Check that character arg is actually
14970 a character. Pass an int to ENCODE_CHAR.
14971 * charset.h (ENCODE_CHAR): Verify that the character argument is no
14972 wider than 'int', as a compile-time check to prevent future regressions
14975 * character.c (char_string): Remove unnecessary casts.
14977 Make sure a 64-bit char is never passed to CHAR_STRING.
14978 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
14979 by silently ignoring the top 32 bits, allowing some values
14980 that were far too large to be valid characters.
14981 * character.h: Include <verify.h>.
14982 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
14983 arguments are no wider than unsigned, as a compile-time check
14984 to prevent future regressions in this area.
14986 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
14987 (Fsubst_char_in_region):
14989 * xdisp.c (decode_mode_spec_coding):
14990 Adjust to CHAR_STRING's new requirement.
14991 * editfns.c (Finsert_char, Fsubst_char_in_region):
14992 * fns.c (concat): Check that character args are actually
14993 characters. Without this test, these functions did the wrong
14994 thing with wildly out-of-range values on 64-bit hosts.
14996 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
14997 These casts should not be needed on 32-bit hosts, either.
14998 * keyboard.c (read_char):
14999 * lread.c (Fload): Remove casts to unsigned.
15001 * lisp.h (UNSIGNED_CMP): New macro.
15002 This fixes comparison bugs on 64-bit hosts.
15003 (ASCII_CHAR_P): Use it.
15004 * casefiddle.c (casify_object):
15005 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
15006 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
15007 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
15008 * dispextern.h (FACE_FROM_ID):
15009 * keyboard.c (read_char): Use UNSIGNED_CMP.
15011 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
15012 not to EMACS_INT, to avoid GCC warning.
15014 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
15016 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
15017 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
15018 isn't needed on 32-bit machines.
15020 * buffer.c (Fgenerate_new_buffer_name):
15021 Use EMACS_INT for count, not int.
15022 (advance_to_char_boundary): Return EMACS_INT, not int.
15024 * data.c (Qcompiled_function): Now static.
15026 * window.c (window_body_lines): Now static.
15028 * image.c (gif_load): Rename local to avoid shadowing.
15030 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
15031 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
15032 * alloc.c (make_save_value): Integer argument is now of type
15033 ptrdiff_t, not int.
15034 (mark_object): Use ptrdiff_t, not int.
15035 * lisp.h (pD): New macro.
15036 * print.c (print_object): Use it.
15038 * alloc.c: Use EMACS_INT, not int, to count objects.
15039 (total_conses, total_markers, total_symbols, total_vector_size)
15040 (total_free_conses, total_free_markers, total_free_symbols)
15041 (total_free_floats, total_floats, total_free_intervals)
15042 (total_intervals, total_strings, total_free_strings):
15043 Now EMACS_INT, not int. All uses changed.
15044 (Fgarbage_collect): Compute overall total using a double, so that
15045 integer overflow is less likely to be a problem. Check for overflow
15046 when converting back to an integer.
15047 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
15048 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
15049 These were 'int' variables that could overflow on 64-bit hosts;
15050 they were never used, so remove them instead of repairing them.
15051 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
15052 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
15053 Previously, this ceilinged at INT_MAX, but that doesn't work on
15055 (allocate_pseudovector): Don't use EMACS_INT when int would do.
15057 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
15058 (allocate_vectorlike): Check for ptrdiff_t overflow.
15059 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
15060 when a (possibly-narrower) signed value would do just as well.
15061 We prefer using signed arithmetic, to avoid comparison confusion.
15063 * alloc.c: Catch some string size overflows that we were missing.
15064 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
15065 for convenience in STRING_BYTES_MAX.
15066 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
15067 The definition here is exact; the one in lisp.h was approximate.
15068 (allocate_string_data): Check for string overflow. This catches
15069 some instances we weren't catching before. Also, it catches
15070 size_t overflow on (unusual) hosts where SIZE_MAX <= min
15071 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
15072 and ptrdiff_t and EMACS_INT are both 64 bits.
15074 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
15075 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
15076 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
15078 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
15080 * alloc.c (Fmake_string): Check for out-of-range init.
15082 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
15084 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
15086 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
15088 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
15089 xg_get_default_scrollbar_width.
15091 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
15092 (int_gtk_range_get_value): Move to the scroll bar part of the file.
15093 (style_changed_cb): Call update_theme_scrollbar_width and call
15094 x_set_scroll_bar_default_width and xg_frame_set_char_size for
15095 all frames (Bug#8505).
15096 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
15097 Call gtk_window_set_resizable if HAVE_GTK3.
15098 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
15099 and height if HAVE_GTK3 (Bug#8505).
15100 (scroll_bar_width_for_theme): New variable.
15101 (update_theme_scrollbar_width): New function.
15102 (xg_get_default_scrollbar_width): Move code to
15103 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
15104 (xg_initialize): Call update_theme_scrollbar_width.
15106 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
15108 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
15110 2011-06-12 Martin Rudalics <rudalics@gmx.at>
15112 * frame.c (make_frame): Call other_buffer_safely instead of
15115 * window.c (temp_output_buffer_show): Call display_buffer with
15116 second argument Vtemp_buffer_show_specifiers and reset latter
15117 immediately after the call.
15118 (Vtemp_buffer_show_specifiers): New variable.
15119 (auto_window_vscroll_p, next_screen_context_lines)
15120 (Vscroll_preserve_screen_position): Remove leading asterisks from
15123 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
15125 Fix minor problems found by GCC 4.6.0 static checking.
15126 * buffer.c (Qclone_number): Remove for now, as it's unused.
15127 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
15128 (record_buffer): Remove unused local.
15129 * frame.c (other_visible_frames, frame_buffer_list): Now static.
15130 (set_frame_buffer_list): Remove; unused.
15131 * frame.h (other_visible_frames): Remove decl.
15132 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
15133 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
15134 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
15136 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
15137 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
15138 Define only if HAVE_GPM.
15139 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
15140 (update_hints_inhibit): Remove; never set. All uses removed.
15141 * widgetprv.h (emacsFrameClassRec): Remove decl.
15142 * window.c (delete_deletable_window): Now returns void, since it
15143 wasn't returning anything.
15144 (compare_window_configurations): Remove unused locals.
15145 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
15146 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
15147 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
15148 the same widths as pointers. This follows up on the 2011-05-06 patch.
15149 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
15150 * xterm.h: Likewise.
15151 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.
15153 2011-06-12 Juanma Barranquero <lekktu@gmail.com>
15155 * makefile.w32-in: Update dependencies.
15156 (LISP_H): Add lib/intprops.h.
15158 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
15160 * image.c (gif_load): Add animation frame delay to the metadata.
15161 (syms_of_image): Use DEFSYM. New symbol `delay'.
15163 2011-06-11 Martin Rudalics <rudalics@gmx.at>
15165 * window.c (delete_deletable_window): Re-add.
15166 (Fset_window_configuration): Rewrite to handle dead buffers and
15167 consequently deletable windows.
15168 (window_tree, Fwindow_tree): Remove. Supply functionality in
15170 (compare_window_configurations): Simplify code.
15172 2011-06-11 Andreas Schwab <schwab@linux-m68k.org>
15174 * image.c (imagemagick_load_image): Fix type mismatch.
15175 (Fimagemagick_types): Likewise.
15177 * window.h (replace_buffer_in_windows): Declare.
15179 2011-06-11 Martin Rudalics <rudalics@gmx.at>
15181 * buffer.c: New Lisp objects Qbuffer_list_update_hook and
15182 Qclone_number. Remove external declaration of Qdelete_window.
15183 (Fbuffer_list): Rewrite doc-string. Minor restructuring of
15185 (Fget_buffer_create, Fmake_indirect_buffer, Frename_buffer):
15186 Run Qbuffer_list_update_hook if allowed.
15187 (Fother_buffer): Rewrite doc-string. Major rewrite for new
15188 buffer list implementation.
15189 (other_buffer_safely): New function.
15190 (Fkill_buffer): Replace call to replace_buffer_in_all_windows by
15191 calls to replace_buffer_in_windows and
15192 replace_buffer_in_windows_safely. Run Qbuffer_list_update_hook
15194 (record_buffer): Inhibit quitting and rewrite using quittable
15195 functions. Run Qbuffer_list_update_hook if allowed.
15196 (Frecord_buffer, Funrecord_buffer): New functions.
15197 (switch_to_buffer_1, Fswitch_to_buffer): Remove.
15198 Move switch-to-buffer to window.el.
15199 (bury-buffer): Move to window.el.
15200 (Vbuffer_list_update_hook): New variable.
15202 * lisp.h (other_buffer_safely): Add prototype in buffer.c
15205 * window.h (resize_frame_windows): Move up in code.
15206 (Fwindow_frame): Remove EXFUN.

15656 bidirectional text is supported only in multibyte buffers.
15657 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
15658 it to initialize the frame_window_p member of struct bidi_it.
15659 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
15660 (bidi_resolve_explicit, bidi_resolve_weak)
15661 (bidi_level_of_next_char, bidi_move_to_visually_next): Abort if
15662 bidi_it->nchars is non-positive.
15663 (bidi_level_of_next_char): Don't try to lookup the cache for the
15664 next/previous character if nothing is cached there yet, or if we
15665 were just reseat()'ed to a new position.
15667 * xdisp.c (set_cursor_from_row): Set start and stop points
15668 according to the row's direction when priming the loop that looks
15669 for the glyph on which to display cursor.
15670 (single_display_spec_intangible_p): Function deleted.
15671 (display_prop_intangible_p): Reimplement to call
15672 handle_display_spec instead of single_display_spec_intangible_p.
15673 Accept 3 additional arguments needed by handle_display_spec.
15674 This fixes incorrect cursor motion across display property with complex
15675 values: lists, `(when COND...)' forms, etc.
15676 (single_display_spec_string_p): Support property values that are
15677 lists with the argument STRING its top-level element.
15678 (display_prop_string_p): Fix the condition for processing a
15679 property that is a list to be consistent with handle_display_spec.
15680 (handle_display_spec): New function, refactored from the
15681 last portion of handle_display_prop.
15682 (compute_display_string_pos): Accept additional argument
15683 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
15684 value of a `display' property is a "replacing spec".
15685 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
15686 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
15687 the display property, but just return a value indicating whether
15688 the display property will replace the characters it covers.
15689 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
15690 frame_window_p members of struct bidi_it.
15691 (compute_display_string_pos, compute_display_string_end):
15693 (push_it): Accept second argument POSITION, where pop_it should
15694 jump to continue iteration.
15695 (reseat_1): Initialize bidi_it.disp_pos.
15697 * keyboard.c (adjust_point_for_property): Adjust the call to
15698 display_prop_intangible_p to its new signature.
15700 * dispextern.h (struct bidi_it): New member frame_window_p.
15701 (bidi_init_it): Update prototypes.
15702 (display_prop_intangible_p): Update prototype.
15703 (compute_display_string_pos, compute_display_string_end):
15704 Declare prototypes.
15705 (struct bidi_it): New members nchars and disp_pos. ch_len is now
15708 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
15710 Malloc failure behavior now depends on size of allocation.
15711 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
15712 * lisp.h: Change signatures accordingly.
15713 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
15714 All callers changed. (Bug#8762)
15716 * gnutls.c: Use Emacs's memory allocators.
15717 Without this change, the gnutls library would invoke malloc etc.
15718 directly, which causes problems on non-SYNC_INPUT hosts, and which
15719 runs afoul of improving memory_full behavior. (Bug#8761)
15720 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
15721 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
15722 xfree instead of the default malloc, realloc, free.
15723 (Fgnutls_boot): No need to check for memory allocation failure,
15724 since xmalloc does that for us.
15726 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
15727 * category.c (hash_get_category_set):
15728 * ccl.c (ccl_driver):
15729 * charset.c (Fdefine_charset_internal):

15732 (composition_gstring_put_cache):
15733 * composite.h (struct composition.hash_index):
15734 * dispextern.h (struct image.hash):
15735 * fns.c (next_almost_prime, larger_vector, cmpfn_eql)
15736 (cmpfn_equal, cmpfn_user_defined, hashfn_eq, hashfn_eql)
15737 (hashfn_equal, hashfn_user_defined, make_hash_table)
15738 (maybe_resize_hash_table, hash_lookup, hash_put)
15739 (hash_remove_from_table, hash_clear, sweep_weak_table, SXHASH_COMBINE)
15740 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
15741 (Fsxhash, Fgethash, Fputhash, Fmaphash):
15742 * image.c (make_image, search_image_cache, lookup_image)
15743 (xpm_put_color_table_h):
15744 * lisp.h (struct Lisp_Hash_Table):
15745 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
15746 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
15747 for hashes and hash indexes, instead of 'unsigned' and 'int'.
15748 * alloc.c (allocate_vectorlike):
15749 Check for overflow in vector size calculations.
15750 * ccl.c (ccl_driver):
15751 Check for overflow when converting EMACS_INT to int.
15752 * fns.c, image.c: Remove unnecessary static decls that would otherwise
15753 need to be updated by these changes.
15754 * fns.c (make_hash_table, maybe_resize_hash_table):
15755 Check for integer overflow with large hash tables.
15756 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
15757 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
15758 (SXHASH_REDUCE): New macro.
15759 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
15760 Use it instead of discarding useful hash info with large hash values.
15761 (sxhash_float): New function.
15762 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
15763 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
15764 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
15765 Rewrite to use FIXNUM_BITS, as this simplifies things.
15766 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
15767 Adjust signatures to match updated version of code.
15768 (consing_since_gc): Now EMACS_INT, since a single hash table can
15769 use more than INT_MAX bytes.
15771 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
15773 Make it possible to build with GCC-4.6+ -O2 -flto.
15775 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
15777 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
15779 * minibuf.c (get_minibuffer, read_minibuf_unwind):
15780 Call minibuffer-inactive-mode.
15782 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
15784 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
15785 Update dependencies.
15787 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
15789 * data.c (init_data): Remove code for UTS, this system is not
15792 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
15794 Don't force ./temacs to start in terminal mode.
15796 * frame.c (make_initial_frame): Initialize faces in all cases, not
15797 only when CANNOT_DUMP is defined.
15798 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
15800 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
15802 * dispnew.c (add_window_display_history): Use const for the string
15803 pointer. Remove declaration, not needed.
15805 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
15807 Use 'inline', not 'INLINE'.
15808 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
15809 * alloc.c, fontset.c (INLINE): Remove.
15810 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
15811 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
15812 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
15813 * gmalloc.c (register_heapinfo): Use inline unconditionally.
15814 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
15816 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
15818 Make it possible to run ./temacs.
15820 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
15821 syms_of_callproc does the same thing. Remove test for
15822 "initialized", do it in the caller.
15823 * emacs.c (main): Avoid calling set_initial_environment when dumping.
15825 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
15827 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
15828 (read_minibuf): Use get_minibuffer.
15829 (syms_of_minibuf): Use DEFSYM.
15830 (Qmetadata): New var.
15831 * data.c (Qbuffer): Don't make it static.
15832 (syms_of_data): Use DEFSYM.
15834 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
15836 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
15837 (CCL_CODE_MIN): New macro.
15839 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
15841 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
15843 * eval.c (Qdebug): Now static.
15844 * lisp.h (Qdebug): Remove decl. This reverts a part of the
15845 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
15846 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
15848 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
15850 * image.c: Various fixes to ImageMagick code comments.
15851 (Fimagemagick_types): Doc fix.
15853 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
15855 Minor fixes prompted by GCC 4.6.0 warnings.
15857 * xselect.c (converted_selections, conversion_fail_tag): Now static.
15859 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
15860 (x_clipboard_manager_save_all): Move extern decl to ...
15861 * xterm.h: ... here, so that it can be checked for consistency.
15863 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
15865 * xselect.c (x_clipboard_manager_save_frame)
15866 (x_clipboard_manager_save_all): New functions.
15867 (Fx_clipboard_manager_save): Lisp function deleted.
15869 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
15870 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
15872 * xterm.h: Update prototype.
15874 2011-05-28 William Xu <william.xwl@gmail.com>
15876 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
15877 exiting (Bug#8239).
15879 2011-05-28 Jim Meyering <meyering@redhat.com>
15881 Avoid a sign-extension bug in crypto_hash_function.
15882 * fns.c (to_uchar): Define.
15883 (crypto_hash_function): Use it to convert some newly-signed
15884 variables to unsigned, to avoid sign-extension bugs. For example,
15885 without this change, (md5 "truc") would evaluate to
15886 45723a2aff78ff4fff7fff1114760e62 rather than the expected
15887 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
15888 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
15890 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
15892 Integer overflow fixes.
15894 * dbusbind.c: Serial number integer overflow fixes.
15895 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
15896 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
15897 to hold a serial number that is too large for a fixnum.
15898 (Fdbus_method_return_internal, Fdbus_method_error_internal):
15899 Check for serial numbers out of range. Decode any serial number
15900 that was so large that it became a float. (Bug#8722)
15902 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
15903 (Fdbus_call_method, Fdbus_call_method_asynchronously):
15904 Use XFASTINT rather than XUINT when numbers are nonnegative.
15905 (xd_append_arg, Fdbus_method_return_internal):
15906 (Fdbus_method_error_internal): Likewise. Also, for unsigned
15907 arguments, check that Lisp number is nonnegative, rather than
15908 silently wrapping negative numbers around. (Bug#8722)
15909 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
15912 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
15914 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
15916 ccl: Add integer overflow checks.
15917 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
15918 (IN_INT_RANGE): New macros.
15919 (ccl_driver): Use them to check for integer overflow when
15920 decoding a CCL program. Many of the new checks are whether XINT (x)
15921 fits in int; it doesn't always, on 64-bit hosts. The new version
15922 doesn't catch all possible integer overflows, but it's an
15923 improvement. (Bug#8719)
15925 * alloc.c (make_event_array): Use XINT, not XUINT.
15926 There's no need for unsigned here.
15928 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
15929 This follows up to the 2011-05-06 change that substituted uintptr_t
15930 for EMACS_INT. This case wasn't caught back then.
15932 Rework Fformat to avoid integer overflow issues.
15933 * editfns.c: Include <float.h> unconditionally, as it's everywhere
15934 now (part of C89). Include <verify.h>.
15935 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
15936 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
15937 (Fformat): Avoid the prepass trying to compute sizes; it was only
15938 approximate and thus did not catch overflow reliably. Instead, walk
15939 through the format just once, formatting and computing sizes as we go,
15940 checking for integer overflow at every step, and allocating a larger
15941 buffer as needed. Keep track separately whether the format is
15942 multibyte. Keep only the most-recently calculated precision, rather
15943 than them all. Record whether each argument has been converted to
15944 string. Use EMACS_INT, not int, for byte and char and arg counts.
15945 Support field widths and precisions larger than INT_MAX. Avoid
15946 sprintf's undefined behavior with conversion specifications such as %#d
15947 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
15948 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
15949 formatting out-of-range floating point numbers with int
15950 formats. (Bug#8668)
15952 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
15954 * data.c: Avoid integer truncation in expressions involving floats.
15955 * data.c: Include <intprops.h>.
15956 (arith_driver): When there's an integer overflow in an expression
15957 involving floating point, convert the integers to floating point
15958 so that the resulting value does not suffer from catastrophic
15959 integer truncation. For example, on a 64-bit host (* 4
15960 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
15961 Do not rely on undefined behavior after integer overflow.
15963 merge count_size_as_multibyte, parse_str_to_multibyte
15964 * character.c, character.h (count_size_as_multibyte):
15965 Rename from parse_str_to_multibyte; all uses changed.
15966 Check for integer overflow.
15967 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
15968 since it's now a duplicate of the other. This is more of
15969 a character than a buffer op, so better that it's in character.c.
15970 * fns.c, print.c: Adjust to above changes.
15972 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
15974 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
15976 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
15978 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
15979 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
15980 (x_clipboard_manager_save): Now static.
15981 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
15983 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
15984 (crypto_hash_function): Now static.
15985 Fix pointer signedness problems. Avoid unnecessary initializations.
15987 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
15989 * termhooks.h (Vselection_alist): Make it terminal-local.
15991 * terminal.c (create_terminal): Initialize it.
15993 * xselect.c: Support for clipboard managers.
15994 (Vselection_alist): Move to termhooks.h as terminal-local var.
15995 (LOCAL_SELECTION): New macro.
15996 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
15997 (symbol_to_x_atom): Remove gratuitous arg.
15998 (x_handle_selection_request, lisp_data_to_selection_data)
15999 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
16000 (x_own_selection, x_get_local_selection, x_convert_selection):
16001 New arg, specifying work frame. Use terminal-local Vselection_alist.
16002 (some_frame_on_display): Delete unused function.
16003 (Fx_own_selection_internal, Fx_get_selection_internal)
16004 (Fx_disown_selection_internal, Fx_selection_owner_p)
16005 (Fx_selection_exists_p): New optional frame arg.
16006 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
16007 (x_handle_selection_clear): Don't treat other terminals with the
16008 same keyboard specially. Use the terminal-local Vselection_alist.
16009 (x_clear_frame_selections): Use Frun_hook_with_args.
16011 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
16013 * xterm.h: Add support for those atoms.
16015 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
16017 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
16018 (converted_selections, conversion_fail_tag): New global variables.
16019 (x_selection_request_lisp_error): Free the above.
16020 (x_get_local_selection): Remove unnecessary code.
16021 (x_reply_selection_request): Args changed; handle arbitrary array
16022 of converted selections stored in converted_selections.
16023 Separate the XChangeProperty and SelectionNotify steps.
16024 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
16025 (x_convert_selection): New function.
16026 (x_handle_selection_event): Simplify.
16027 (x_get_foreign_selection): Don't ignore incoming requests while
16028 waiting for an answer; this will fail when we implement
16029 SAVE_TARGETS, and seems unnecessary anyway.
16030 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
16031 (Vx_sent_selection_functions): Doc fix.
16033 2011-05-26 Leo Liu <sdl.web@gmail.com>
16035 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
16037 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16039 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
16041 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
16042 for fringe update if it has periodic bitmap.
16043 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
16044 and fringe_bitmap_periodic_p.
16046 * fringe.c (get_fringe_bitmap_data): New function.
16047 (draw_fringe_bitmap_1, update_window_fringes): Use it.
16048 (update_window_fringes): Record periodicity of fringe bitmap in glyph
16049 row. Mark glyph row for fringe update if periodicity changed.
16051 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
16052 for fringe update unless it has periodic bitmap.
16054 2011-05-25 Kenichi Handa <handa@m17n.org>
16056 * xdisp.c (get_next_display_element): Set correct it->face_id for
16057 a static composition.
16059 2011-05-24 Leo Liu <sdl.web@gmail.com>

16065 (Fmd5): Use crypto_hash_function.
16066 (syms_of_fns): Add Ssha1.
16068 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
16070 * gnutls.c: Remove unused macros.
16071 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
16072 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
16073 Remove macros that are defined and never used.
16074 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
16076 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
16078 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
16079 (Fx_get_selection_internal): Minor cleanup.
16080 (Fx_own_selection_internal): Rename arguments for consistency with
16083 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
16085 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
16087 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
16089 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
16091 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16093 * dispnew.c (scrolling_window): Don't exclude the case that the
16094 last enabled row in the desired matrix touches the bottom boundary.
16096 2011-05-21 Glenn Morris <rgm@gnu.org>
16098 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
16099 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
16100 and add some more files.
16102 2011-05-20 Eli Zaretskii <eliz@gnu.org>
16104 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
16105 report_file_error introduced by the change from 2011-05-07.
16107 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
16109 * systime.h (Time): Define only if emacs is defined.
16110 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
16111 where the include path doesn't have X11/X.h by default. See
16112 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
16114 2011-05-20 Kenichi Handa <handa@m17n.org>
16116 * composite.c (find_automatic_composition): Fix previous change.
16118 2011-05-20 Glenn Morris <rgm@gnu.org>
16120 * lisp.mk: New file, split from Makefile.in.
16121 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
16122 (shortlisp): Remove.
16123 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
16125 2011-05-19 Glenn Morris <rgm@gnu.org>
16127 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
16128 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
16129 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
16130 (lisp): Set the order to that of loadup.el.
16131 (shortlisp): Make it a copy of $lisp.
16132 (SOME_MACHINE_LISP): Remove.
16133 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
16134 Use just $shortlisp, not $SOME_MACHINE_LISP too.
16136 2011-05-18 Kenichi Handa <handa@m17n.org>
16138 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
16139 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
16140 (find_automatic_composition): Mostly rewrite for efficiency.
16142 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
16144 * makefile.w32-in: Update dependencies.
16146 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
16148 * menu.c: Include limits.h (fixes the MS-Windows build broken by
16149 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
16151 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
16153 Fix some integer overflow issues, such as string length overflow.
16155 * insdel.c (count_size_as_multibyte): Check for string overflow.
16157 * character.c (lisp_string_width): Check for string overflow.
16158 Use EMACS_INT, not int, for string indexes and lengths; in
16159 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
16160 the resulting string length overflows an EMACS_INT; instead,
16161 report a string overflow if no precision given. When checking for
16162 precision exhaustion, use a check that cannot possibly have
16163 integer overflow. (Bug#8675)
16164 * character.h (lisp_string_width): Adjust to new signature.
16166 * alloc.c (string_overflow): New function.
16167 (Fmake_string): Use it. This doesn't change behavior, but saves
16168 a few bytes and will simplify future changes.
16169 * character.c (string_escape_byte8): Likewise.
16170 * lisp.h (string_overflow): New decl.
16172 Fixups, following up to the user-interface timestamp change.
16173 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
16174 for UI timestamps, instead of unsigned long.
16175 * msdos.c (mouse_get_pos): Likewise.
16176 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
16177 * w32gui.h (Time): Define by including "systime.h" rather than by
16178 declaring it ourselves. (Bug#8664)
16180 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
16181 * image.c (clear_image_cache): Likewise.
16183 * term.c (term_mouse_position): Don't assume time_t wraparound.
16185 Be more systematic about user-interface timestamps.
16186 Before, the code sometimes used 'Time', sometimes 'unsigned long',
16187 and sometimes 'EMACS_UINT', to represent these timestamps.
16188 This change causes it to use 'Time' uniformly, as that's what X uses.
16189 This makes the code easier to follow, and makes it easier to catch
16190 integer overflow bugs such as Bug#8664.
16191 * frame.c (Fmouse_position, Fmouse_pixel_position):
16192 Use Time, not unsigned long, for user-interface timestamps.
16193 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
16194 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
16195 * keyboard.h (last_event_timestamp): Likewise.
16196 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
16197 * menu.h (xmenu_show): Likewise.
16198 * term.c (term_mouse_position): Likewise.
16199 * termhooks.h (struct input_event.timestamp): Likewise.
16200 (struct terminal.mouse_position_hook): Likewise.
16201 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
16202 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
16203 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
16204 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
16205 what it was before.
16206 * menu.h, termhooks.h: Include "systime.h", for Time.
16208 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
16209 Don't assume that the difference between two unsigned long values
16210 can fit into an integer. At this point, we know button_down_time
16211 <= event->timestamp, so the difference must be nonnegative, so
16212 there's no need to cast the result if double-click-time is
16213 nonnegative, as it should be; check that it's nonnegative, just in
16214 case. This bug is triggered when events are more than 2**31 ms
16215 apart (about 25 days). (Bug#8664)
16217 * xselect.c (last_event_timestamp): Remove duplicate decl.
16218 (x_own_selection): Remove needless cast to unsigned long.
16220 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
16221 that always fit in int. Use a sentinel instead of a counter, to
16222 avoid a temp and to allay GCC's concerns about possible int overflow.
16223 * frame.h (struct frame): Use int for menu_bar_items_used
16224 instead of EMACS_INT, since it always fits in int.
16226 * menu.c (grow_menu_items): Check for int overflow.
16228 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
16230 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
16231 Before, the code was not consistent. These values cannot exceed
16232 2**31 - 1 so there's no need to make them unsigned.
16233 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
16234 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
16235 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
16237 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
16239 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
16240 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
16241 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
16242 presumably because the widths might not match.
16244 * window.c (size_window): Avoid needless test at loop start.
16246 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
16248 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
16250 2011-05-12 Drew Adams <drew.adams@oracle.com>
16252 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
16254 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16256 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
16257 `width' to `bar_area_x' and `bar_area_width', respectively.
16258 (x_scroll_run): Take account of fringe background extension.
16260 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
16261 Rename local vars `left' and `width' to `bar_area_x' and
16262 `bar_area_width', respectively.
16263 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
16264 background extension.
16266 2011-05-10 Jim Meyering <meyering@redhat.com>
16268 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
16270 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
16272 * image.c (Finit_image_library): Return t for built-in image types,
16273 like pbm and xbm. (Bug#8640)
16275 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
16277 * w32menu.c (set_frame_menubar): Fix submenu allocation.
16279 2011-05-07 Eli Zaretskii <eliz@gnu.org>
16281 * w32console.c (Fset_screen_color): Doc fix.
16282 (Fget_screen_color): New function.
16283 (syms_of_ntterm): Defsubr it.
16285 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
16286 unlink the temporary file if Fcall_process didn't create it in the
16288 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
16289 child process will be redirected to a file specified with `:file'.
16290 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
16291 cue to call_process_cleanup not to close that handle.
16293 2011-05-07 Ben Key <bkey76@gmail.com>
16295 * makefile.w32-in: The bootstrap-temacs rule now makes use of
16296 one of two shell specific rules, either bootstrap-temacs-CMD or
16297 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
16298 to the previous implementation of the bootstrap-temacs rule.
16299 The bootstrap-temacs-CMD rule is similar to the previous
16300 implementation of the bootstrap-temacs rule except that it
16301 makes use of the ESC_CFLAGS variable instead of the CFLAGS
16304 These changes, along with some changes to nt/configure.bat,
16305 nt/gmake.defs, and nt/nmake.defs, are required to extend my
16306 earlier fix to add support for --cflags and --ldflags options
16307 that include quotes so that it works whether make uses cmd or
16310 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
16312 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
16313 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
16315 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
16316 a string. Handle both cases.
16317 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
16318 (Fdbus_register_method): Use Qinvalid_function.
16320 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
16322 * makefile.w32-in: Update dependencies.
16323 (LISP_H): Add inttypes.h and stdin.h.
16324 (PROCESS_H): Add unistd.h.
16326 2011-05-06 Eli Zaretskii <eliz@gnu.org>
16328 * lread.c: Include limits.h (fixes the MS-Windows build broken by
16329 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
16331 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
16333 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
16335 * term.c (vfatal): Remove stray call to va_end.
16336 It's not needed and the C Standard doesn't allow it here anyway.
16338 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
16339 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
16341 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
16344 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
16346 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
16348 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
16350 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
16352 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
16354 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
16355 * charset.c (Fdefine_charset_internal): Don't initialize
16356 charset.code_space[15]. The value was garbage, on hosts with
16357 32-bit int (Bug#8600).
16359 * lread.c (read_integer): Be more consistent with string-to-number.
16360 Use string_to_number to do the actual conversion; this avoids
16361 rounding errors and fixes some other screwups. Without this fix,
16362 for example, #x1fffffffffffffff was misread as -2305843009213693952.
16363 (digit_to_number): Move earlier, for benefit of read_integer.
16364 Return -1 if the digit is out of range for the base, -2 if it is
16365 not a digit in any supported base. (Bug#8602)
16367 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
16369 * dispnew.c (scrolling_window): Return 1 if we scrolled,
16370 to match comment at start of function. This also removes a
16371 GCC warning about overflow in a 32+64-bit port.
16373 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
16375 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
16376 Reported by Stefan Monnier in
16377 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
16378 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
16379 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
16381 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
16382 (EMACS_UINTPTR): Likewise, with uintptr_t.
16384 * lisp.h: Prefer 64-bit EMACS_INT if available.
16385 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
16386 on 32-bit hosts that have 64-bit int, so that they can access
16388 However, temporarily disable this change unless the temporary
16389 symbol WIDE_EMACS_INT is defined.
16391 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
16393 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
16394 This removes an assumption that EMACS_INT and long are the same
16395 width as pointers. The assumption is true for Emacs porting targets
16396 now, but we want to make other targets possible.
16397 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
16398 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
16399 In the rest of the code, change types of integers that hold casted
16400 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
16401 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
16402 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
16403 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
16404 No need to cast type when ORing.
16405 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
16406 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
16407 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
16408 assume EMACS_INT is the same width as char *.
16409 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
16410 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
16411 Remove no-longer-needed casts.
16412 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
16413 (xg_tool_bar_help_callback, xg_make_tool_item):
16414 Use EMACS_INTPTR to hold an integer
16415 that will be cast to void *; this can avoid a GCC warning
16416 if EMACS_INT is not the same width as void *.
16417 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
16418 * xdisp.c (display_echo_area_1, resize_mini_window_1):
16419 (current_message_1, set_message_1):
16420 Use a local to convert to proper width without a cast.
16421 * xmenu.c (dialog_selection_callback): Likewise.
16423 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
16424 Also, don't assume VALBITS / RAND_BITS is less than 5,
16425 and don't rely on undefined behavior when shifting a 1 left into
16427 * lisp.h (get_random): Change signature to match.
16429 * lread.c (hash_string): Use size_t, not int, for hash computation.
16430 Normally we prefer signed values; but hashing is special, because
16431 it's better to use unsigned division on hash table sizes so that
16432 the remainder is nonnegative. Also, size_t is the natural width
16433 for hashing into memory. The previous code used 'int', which doesn't
16434 retain enough info to hash well into very large tables.
16435 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
16437 * dbusbind.c: Don't possibly lose pointer info when converting.
16438 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
16439 Use XPNTR rather than XHASH, so that the high-order bits of
16440 the pointer aren't lost when converting through void *.
16442 * eval.c (Fautoload): Don't double-shift a pointer.
16444 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
16446 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
16448 * gnutls.c (DEF_GNUTLS_FN):
16449 * image.c (DEF_IMGLIB_FN): Make function pointers static.
16451 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
16453 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
16456 2011-05-05 Eli Zaretskii <eliz@gnu.org>
16458 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
16459 New version that can reserve upto 2GB of heap space.
16461 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
16463 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
16465 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
16467 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
16468 `gnutls_certificate_set_x509_key_file'.
16470 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
16472 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
16473 Update dependencies.
16475 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
16477 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
16478 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
16479 Remove unused parameter `fildes'.
16480 * process.c (read_process_output, send_process): Don't pass it.
16482 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
16484 Fix previous change: the library cache is defined in w32.c.
16485 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
16486 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
16488 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
16490 Implement dynamic loading of GnuTLS on Windows.
16492 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
16493 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
16494 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
16497 * gnutls.c (Qgnutls_dll): Define.
16498 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
16499 (gnutls_*): Declare function pointers.
16500 (init_gnutls_functions): New function to initialize function pointers.
16501 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
16502 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
16503 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
16504 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
16505 (emacs_gnutls_write, emacs_gnutls_read)

16581 rather than `XVECTOR (FOO)->size'.
16583 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
16584 inttypes.h, as a gnulib replacement is used if it not available in

16599 charbuf for the composition carryover bytes.
16601 2011-04-21 Eli Zaretskii <eliz@gnu.org>

16604 aborting when %lld or %lll format is passed.
16605 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
16606 %llo or %llx format is passed. (Bug#8545)
16608 * window.c (window_scroll_line_based): Use a marker instead of
16609 simple variables to record original value of point. (Bug#7952)
16611 * doprnt.c (doprnt): Fix the case where a multibyte sequence
16612 produced by %s or %c overflows available buffer space. (Bug#8545)
16614 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
16616 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
16617 (SIZE_MAX): Move defn after all includes, as they might #define it.
16619 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
16621 * w32.c (init_environment): Warn about defaulting HOME to C:\.
16623 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
16625 * keyboard.c (Qdelayed_warnings_hook): Define.
16626 (command_loop_1): Run `delayed-warnings-hook'
16627 if Vdelayed_warnings_list is non-nil.
16628 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
16629 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
16631 2011-04-28 Eli Zaretskii <eliz@gnu.org>
16633 * doprnt.c (doprnt): Don't return value smaller than the buffer
16634 size if the message was truncated. (Bug#8545).
16636 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
16638 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)

16645 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
16647 * makefile.w32-in: Update dependencies.
16649 2011-04-27 Eli Zaretskii <eliz@gnu.org>
16651 Improve `doprnt' and its usage. (Bug#8545)
16652 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
16653 `format_end'. Remove support for %l as a conversion specifier.
16654 Don't use xrealloc. Improve diagnostics when the %l size modifier
16655 is used. Update the commentary.
16657 * eval.c (verror): Simplify calculation of size_t.
16659 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
16662 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
16664 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
16667 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
16669 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
16670 This makes this file independent of the recent pseudovector change.
16672 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
16674 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
16676 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
16677 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
16678 Remove unused local.
16679 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
16681 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
16682 GCC 4.6.0 optimizes based on type-based alias analysis.
16683 For example, if b is of type struct buffer * and v of type struct
16684 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
16685 != &v->size, and therefore "v->size = 1; b->size = 2; return
16686 v->size;" must therefore return 1. This assumption is incorrect
16687 for Emacs, since it type-puns struct Lisp_Vector * with many other
16688 types. To fix this problem, this patch adds a new type struct
16689 vectorlike_header that documents the constraints on layout of vectors
16690 and pseudovectors, and helps optimizing compilers not get fooled
16691 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
16692 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
16693 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
16695 (XSETPVECTYPE): Rewrite in terms of new macro.
16696 (XSETPVECTYPESIZE): New macro, specifying both type and size.
16697 This is a bit clearer, and further avoids the possibility of
16698 undesirable aliasing.
16699 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
16700 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
16701 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
16702 since Lisp_Subr is a special case (no "next" field).
16703 (ASIZE): Now uses header.size rather than size.
16704 All previous uses of XVECTOR (foo)->size replaced to use this macro,
16705 to avoid the hassle of writing XVECTOR (foo)->header.size.
16706 (struct vectorlike_header): New type.
16707 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
16708 object, to help avoid aliasing.
16709 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
16710 (SUBRP): Likewise, since Lisp_Subr is a special case.
16711 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
16712 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
16713 (struct Lisp_Hash_Table): Combine first two members into a single
16714 struct vectorlike_header member. All uses of "size" and "next" members
16715 changed to be "header.size" and "header.next".
16716 * buffer.h (struct buffer): Likewise.
16717 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
16718 * frame.h (struct frame): Likewise.
16719 * process.h (struct Lisp_Process): Likewise.
16720 * termhooks.h (struct terminal): Likewise.
16721 * window.c (struct save_window_data, struct saved_window): Likewise.
16722 * window.h (struct window): Likewise.
16723 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
16724 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
16725 * buffer.c (init_buffer_once): Likewise.
16726 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
16728 * process.c (Fformat_network_address): Use local var for size,
16731 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
16733 Make the Lisp reader and string-to-float more consistent (Bug#8525)
16734 * data.c (atof): Remove decl; no longer used or needed.
16735 (digit_to_number): Move to lread.c.
16736 (Fstring_to_number): Use new string_to_number function, to be
16737 consistent with how the Lisp reader treats infinities and NaNs.
16738 Do not assume that floating-point numbers represent EMACS_INT
16739 without losing information; this is not true on most 64-bit hosts.
16740 Avoid double-rounding errors, by insisting on integers when
16741 parsing non-base-10 numbers, as the documentation specifies.
16742 * lisp.h (string_to_number): New decl, replacing ...
16743 (isfloat_string): Remove.
16744 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
16745 (read1): Do not accept +. and -. as integers; this
16746 appears to have been a coding error. Similarly, do not accept
16747 strings like +-1e0 as floating point numbers. Do not report
16748 overflow for integer overflows unless the base is not 10 which
16749 means we have no simple and reliable way to continue.
16750 Break out the floating-point parsing into a new
16751 function string_to_number, so that Fstring_to_number parses
16752 floating point numbers consistently with the Lisp reader.
16753 (digit_to_number): Move here from data.c. Make it static inline.
16754 (E_CHAR, EXP_INT): Remove, replacing with ...
16755 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
16756 (string_to_number): New function, replacing isfloat_string.
16757 This function checks for valid syntax and produces the resulting
16758 Lisp float number too. Rework it so that string-to-number
16759 no longer mishandles examples like "1.0e+". Use strtoumax,
16760 so that overflow for non-base-10 numbers is reported only when
16761 there's no portable and simple way to convert to floating point.
16763 * textprop.c (set_text_properties_1): Rewrite for clarity,
16764 and to avoid GCC warning about integer overflow.
16766 * intervals.h (struct interval): Use EMACS_INT for members
16767 where EMACS_UINT might cause problems. See
16768 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
16769 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
16770 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
16772 (offset_intervals): Tell GCC not to worry about length overflow
16773 when negating a negative length.
16775 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
16776 (overrun_check_free): Likewise.
16778 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
16779 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
16782 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
16783 (gnutls_make_error): Rename local to avoid shadowing.
16784 (gnutls_emacs_global_deinit): ifdef out; not used.
16785 (Fgnutls_boot): Use const for pointer to readonly storage.
16786 Comment out unused local. Fix pointer signedness problems.
16788 * lread.c (openp): Don't stuff size_t into an 'int'.
16789 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
16790 about possible signed overflow.
16792 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
16793 (GDK_KEY_g): Don't define if already defined.
16794 (xg_prepare_tooltip): Avoid pointer signedness problem.
16795 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
16797 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
16798 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
16800 * xfns.c (Fx_window_property): Simplify a bit,
16801 to make a bit faster and to avoid GCC 4.6.0 warning.
16802 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
16804 * fns.c (internal_equal): Don't assume size_t fits in int.
16806 * alloc.c (compact_small_strings): Tighten assertion a little.
16808 Replace pEd with more-general pI, and fix some printf arg casts.
16809 * lisp.h (pI): New macro, generalizing old pEd macro to other
16810 conversion specifiers. For example, use "...%"pI"d..." rather
16811 than "...%"pEd"...".
16812 (pEd): Remove. All uses replaced with similar uses of pI.
16813 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
16814 * alloc.c (check_pure_size): Don't overflow by converting size to int.
16815 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
16816 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
16817 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
16818 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
16819 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
16821 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
16822 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
16823 * print.c (safe_debug_print, print_object): Likewise.
16824 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
16826 Use pI instead of if-then-else-abort. Use %p to avoid casts,
16827 avoiding the 0 flag, which is not portable.
16828 * process.c (Fmake_network_process): Use pI to avoid cast.
16829 * region-cache.c (pp_cache): Likewise.
16830 * xdisp.c (decode_mode_spec): Likewise.
16831 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
16832 behavior on 64-bit hosts with printf arg.
16833 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
16834 (x_stop_queuing_selection_requests): Likewise.
16835 (x_get_window_property): Don't truncate byte count to an 'int'
16838 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
16839 here, since it parses constructs like leading '-' and spaces,
16840 which are not wanted; and it overflows with large numbers.
16841 Instead, simply match F[0-9]+, which is what is wanted anyway.
16843 * alloc.c: Remove unportable assumptions about struct layout.
16844 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
16845 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
16846 (allocate_vectorlike, make_pure_vector): Use the new macros,
16847 plus offsetof, to remove unportable assumptions about struct layout.
16848 These assumptions hold on all porting targets that I know of, but
16849 they are not guaranteed, they're easy to remove, and removing them
16850 makes further changes easier.
16852 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
16853 This doesn't fix a bug but makes the code clearer.
16854 (string_overrun_cookie): Now const. Use initializers that
16855 don't formally overflow signed char, to avoid warnings.
16856 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
16857 can cause Emacs to crash when string overrun checking is enabled.
16858 (allocate_buffer): Don't assume sizeof (struct buffer) is a
16859 multiple of sizeof (EMACS_INT); it need not be, if
16860 alignof(EMACS_INT) < sizeof (EMACS_INT).
16861 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
16863 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
16865 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
16867 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
16869 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
16870 supposed to be handshaking. (Bug#8556)
16871 Reported by Paul Eggert <eggert@cs.ucla.edu>.
16873 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
16875 * lisp.h (Qdebug): List symbol.
16876 * eval.c (Qdebug): Restore global linkage.
16877 * keyboard.c (debug-on-event): New variable.
16878 (handle_user_signal): Break into debugger when debug-on-event
16879 matches the current signal symbol.
16881 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
16883 * alloc.c (check_sblock, check_string_bytes)
16884 (check_string_free_list): Convert to standard C.
16886 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
16888 * w32.c (emacs_gnutls_push): Fix typo.
16890 2011-04-25 Eli Zaretskii <eliz@gnu.org>
16892 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
16893 "cast to pointer from integer of different size".
16895 Improve doprnt and its use in verror. (Bug#8545)
16896 * doprnt.c (doprnt): Document the set of format control sequences
16897 supported by the function. Use SAFE_ALLOCA instead of always
16900 * eval.c (verror): Don't limit the buffer size at size_max-1, that
16901 is one byte too soon. Don't use xrealloc; instead xfree and
16904 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
16906 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
16909 * gnutls.c: Renamed global_initialized to
16910 gnutls_global_initialized. Added internals for the
16911 :verify-hostname-error, :verify-error, and :verify-flags
16912 parameters of `gnutls-boot' and documented those parameters in the
16913 docstring. Start callback support.
16914 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
16915 unless a fatal error occurred. Call gnutls_alert_send_appropriate
16916 on error. Return error code.
16917 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
16918 (emacs_gnutls_read): Likewise.
16919 (Fgnutls_boot): Return handshake error code.
16920 (emacs_gnutls_handle_error): New function.
16921 (wsaerror_to_errno): Likewise.
16923 * w32.h (emacs_gnutls_pull): Add prototype.
16924 (emacs_gnutls_push): Likewise.
16926 * w32.c (emacs_gnutls_pull): New function for GnuTLS on Woe32.
16927 (emacs_gnutls_push): Likewise.
16929 2011-04-24 Claudio Bley <claudio.bley@gmail.com> (tiny change)

17438 * font.c (font_close_object): Now static.
17439 * font.h (font_close_object): Remove.
17440 * fontset.c (FONTSET_OBJLIST): Remove.
17441 (free_realized_fontset) #if-0 the body, which does nothing.
17442 (face_suitable_for_char_p): #if-0, as it's never called.
17443 * fontset.h (face_suitable_for_char_p): Remove decl.
17444 * xfaces.c (face_at_string_position):
17445 Use FACE_SUITABLE_FOR_ASCII_CHAR_P, not FACE_SUITABLE_FOR_CHAR_P,
17446 since 0 is always ASCII.
17448 * fns.c (weak_hash_tables): Now static.
17450 * fileio.c: Make symbols static if they're not exported.

17469 * editfns.c, lisp.h (get_operating_system_release): Remove.
17470 * process.c (init_process) [DARWIN_OS]: Do it inline, as it is not
17471 worth the hassle of breaking this out.
17473 * xterm.c: Make symbols static if they're not exported.
17474 (x_raise_frame, x_lower_frame, x_wm_set_window_state):

17577 * buffer.c (buffer_count): Remove unused var.

17586 * atimer.h (run_all_atimers): Remove; not exported.
17588 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
17589 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
17590 was inaccessible from Lisp.
17591 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
17592 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
17594 alloc.c: Import and export fewer symbols, and remove unused items.
17595 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
17597 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
17598 it's not optimized away by whole-program optimization.
17599 (message_enable_multibyte, free_misc): Remove.
17600 (catchlist, handlerlist, mark_backtrace):
17601 Declare only if BYTE_MARK_STACK.

17610 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
17611 (mark_backtrace): Define only if BYTE_MARK_STACK.
17612 * xdisp.c (message_enable_multibyte): Now static.
17614 Declare Lisp_Object Q* variables to be 'static' if not exported.
17615 This makes it easier for human readers (and static analyzers)
17616 to see whether these variables are used from other modules.
17617 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
17618 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:

17627 Remove decls of unexported vars.
17628 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
17630 * lisp.h (DEFINE_FUNC): Make sname 'static'.
17632 Make Emacs functions such as Fatom 'static' by default.
17633 This makes it easier for human readers (and static analyzers)
17634 to see whether these functions can be called from other modules.
17635 DEFUN now defines a static function. To make the function external
17636 so that it can be used in other C modules, use the new macro DEFUE.
17637 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
17638 (Finit_image_library):
17639 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
17640 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
17641 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
17642 Remove decls, since these functions are now static.
17643 (Funintern, Fget_internal_run_time): New decls, since these functions
17644 were already external.
17646 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
17647 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

17653 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
17654 Mark functions with DEFUE instead of DEFUN,
17655 if they are used in other modules.
17656 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
17657 decls for now-static functions.
17658 * buffer.h (Fdelete_overlay): Remove decl.
17659 * callproc.c (Fgetenv_internal): Mark as internal.
17660 * composite.c (Fremove_list_of_text_properties): Remove decl.

17668 * image.c (Finit_image_library): New forward static decl.
17669 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
17670 * intervals.h (Fprevious_property_change):
17671 (Fremove_list_of_text_properties): Remove decls.
17672 * keyboard.c (Fthis_command_keys): Remove decl.
17673 (Fcommand_execute): New forward static decl.

17689 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
17691 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
17694 2011-04-13 Eli Zaretskii <eliz@gnu.org>
17696 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
17697 when at ZV. (Bug#8487)
17699 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
17701 * charset.c (Fclear_charset_maps): Use xfree instead of free.
17703 * keyboard.c (parse_tool_bar_item): Likewise.
17704 * sound.c (sound_cleanup, alsa_close): Likewise.
17705 * termcap.c (tgetent): Likewise.
17706 * xfns.c (x_default_font_parameter): Likewise.
17707 * xsettings.c (read_and_apply_settings): Likewise.
17709 * alloc.c (overrun_check_malloc, overrun_check_realloc)
17710 (overrun_check_free): Protoize.
17712 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
17714 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
17715 since callers should never pass a negative size.
17716 Change the signature to match that of plain 'read' and 'write'; see
17717 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
17718 * lisp.h: Update prototypes of emacs_write and emacs_read.
17720 2011-04-11 Eli Zaretskii <eliz@gnu.org>
17722 * xdisp.c (redisplay_window): Don't try to determine the character
17723 position of the scroll margin if the window start point w->startp
17724 is outside the buffer's accessible region. (Bug#8468)
17726 2011-04-10 Eli Zaretskii <eliz@gnu.org>
17728 Fix write-region and its subroutines for buffers > 2GB.
17729 * fileio.c (a_write, e_write): Modify declaration of arguments and
17730 local variables to support buffers larger than 2GB.
17731 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
17733 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
17734 argument, local variables, and return value.
17736 * lisp.h: Update prototypes of emacs_write and emacs_read.
17738 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
17740 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
17742 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
17744 Fix more problems found by GCC 4.6.0's static checks.
17746 * xdisp.c (vmessage): Use a better test for character truncation.
17748 * charset.c (load_charset_map): <, not <=, for optimization,
17749 and to avoid potential problems with integer overflow.
17750 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
17751 * casetab.c (set_identity, shuffle): Likewise.
17752 * editfns.c (Fformat): Likewise.
17753 * syntax.c (skip_chars): Likewise.
17755 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
17756 This also lets GCC 4.6.0 generate slightly better loop code.
17758 * callint.c (Fcall_interactively): <, not <=, for optimization.
17759 (Fcall_interactively): Count the number of arguments produced,
17760 not the number of arguments given. This is simpler and lets GCC
17761 4.6.0 generate slightly better code.
17763 * ftfont.c: Distingish more carefully between FcChar8 and char.
17764 The previous code passed unsigned char * to a functions like
17765 strlen and xstrcasecmp that expect char *, which does not
17766 conform to the C standard.
17767 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
17768 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
17769 char * when the C standard requires it.
17771 * keyboard.c (read_char): Remove unused var.
17773 * eval.c: Port to Windows vsnprintf (Bug#8435).
17774 Include <limits.h>.
17775 (SIZE_MAX): Define if the headers do not.
17776 (verror): Do not give up if vsnprintf returns a negative count.
17777 Instead, grow the buffer. This ports to Windows vsnprintf, which
17778 does not conform to C99. Problem reported by Eli Zaretskii.
17779 Also, simplify the allocation scheme, by avoiding the need for
17780 calling realloc, and removing the ALLOCATED variable.
17782 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
17784 Remove invocations of doprnt, as Emacs now uses vsnprintf.
17785 But keep the doprint source code for now, as we might revamp it
17786 and use it again (Bug#8435).
17787 * lisp.h (doprnt): Remove.
17788 * Makefile.in (base_obj): Remove doprnt.o.
17789 * deps.mk (doprnt.o): Remove.
17791 error: Print 32- and 64-bit integers portably (Bug#8435).
17792 Without this change, on typical 64-bit hosts error ("...%d...", N)
17793 was used to print both 32- and 64-bit integers N, which relied on
17794 undefined behavior.
17795 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
17796 * lisp.h (error, verror): Mark as printf-like functions.
17797 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
17798 Report overflow in size calculations when allocating printf buffer.
17799 Do not truncate output string at its first null byte.
17800 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
17801 Truncate the output at a character boundary, since vsnprintf does not
17803 * charset.c (check_iso_charset_parameter): Convert internal
17804 character to string before calling 'error', since %c now has the
17806 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
17807 overflow when computing char to be passed to 'error'. Do not
17808 pass Lisp_Object to 'error'; pass the integer instead.
17809 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
17810 formatted with plain %d.
17812 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.

17827 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
17828 return ssize_t not "int", and use size_t as the buffer length.
17829 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
17830 * gnutls.h: Update declarations.
17831 * process.c (read_process_output): Use ssize_t, to match.

17947 This avoids several warnings with gcc -Wstrict-overflow.
17948 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
17949 directly, rather than having caller test rule sign. This avoids
17950 some unnecessary tests.
17951 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
17952 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
17953 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.

17970 since the condition is always true at first.
17972 * intervals.c (graft_intervals_into_buffer): Mark var as used.

18003 * eval.c (funcall_lambda): Rename local to avoid shadowing.
18005 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
18006 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
18007 can always succeed if overflow has undefined behavior.
18009 * search.c (boyer_moore, wordify): Remove vars set but not used.
18010 (wordify): Omit three unnecessary tests.
18012 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.

18040 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
18041 that are set but not used.
18043 * xfns.c (make_invisible_cursor): Don't return garbage
18044 if XCreateBitmapFromData fails (Bug#8410).
18046 * xselect.c (x_get_local_selection, x_handle_property_notify):
18047 Remove vars that are set but not used.
18049 * xfns.c (x_create_tip_frame): Remove var that is set but not used.

18071 that is set but not used.
18073 * print.c (print_object): Remove var that is set but not used.
18075 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
18076 The gnulib version avoids calling malloc in the usual case,
18077 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
18078 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
18079 * filelock.c (current_lock_owner): Likewise.
18080 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
18081 * sysdep.c: Include allocator.h, careadlinkat.h.
18082 (emacs_no_realloc_allocator): New static constant.
18083 (emacs_readlink): New function.
18084 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
18085 ../lib/careadlinkat.h.
18087 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
18089 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
18090 first non-nil return value).

18106 (get_per_char_metric): Remove parameter `f', unused since
18107 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

18151 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
18152 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
18153 (FletX, Flet): Obey lexical binding.
18154 (Fcommandp): Handle closures.
18155 (Feval): New `lexical' arg.
18156 (eval_sub): New function extracted from Feval. Use it almost
18157 everywhere where Feval was used. Look up vars in lexical env.
18159 (Ffunctionp): Move from subr.el.

18161 (apply_lambda): Remove `eval_flags'.
18162 (funcall_lambda): Handle closures and new byte-code-functions.
18163 (Fspecial_variable_p): New function.
18164 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,

18167 * doc.c (Fdocumentation, store_function_docstring):
18168 * data.c (Finteractive_form): Handle closures.
18170 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
18173 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
18175 (exec_byte_code): New function extracted from Fbyte_code to handle new
18176 calling convention for byte-code-functions. Add new byte-codes.

18191 (redisplay_window): Even when falling back on "recentering",
18192 position point in the window according to scroll-conservatively,
18193 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
18195 (try_scrolling): When point is above the window, allow searching
18196 as far as scroll_max, or one screenful, to compute vertical
18197 distance from PT to the scroll margin position. This prevents
18198 try_scrolling from unnecessarily failing when
18199 scroll-conservatively is set to a value slightly larger than the
18200 window height. Clean up the case of PT below the margin at bottom
18201 of window: scroll_max can no longer be INT_MAX. When aggressive
18202 scrolling is in use, don't let point enter the opposite scroll
18203 margin as result of the scroll.
18204 (syms_of_xdisp) <scroll-conservatively>: Document the
18205 threshold of 100 lines for never-recentering scrolling.

18214 (redisplay_internal): Remove parameter `preserve_echo_area',
18215 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
18217 * indent.c (Fvertical_motion):
18218 * window.c (window_scroll_pixel_based, Frecenter):
18219 Don't pass `need_y_p' to `move_it_by_lines'.

18253 Don't assume string length fits in int.
18254 (keyremap_step, read_key_sequence): Use size_t for sizes.

18272 * keyboard.c (syms_of_keyboard): Use the same style as later
18273 in this function when indexing through an array. This also
18274 works around GCC bug 48267.
18276 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
18278 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
18280 * chartab.c (sub_char_table_ref_and_range): Redo for slight
18281 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
18283 * keyboard.c, keyboard.h (num_input_events): Now size_t.
18284 This avoids undefined behavior on integer overflow, and is a bit
18285 more convenient anyway since it is compared to a size_t variable.
18287 Variadic C functions now count arguments with size_t, not int.
18288 This avoids an unnecessary limitation on 64-bit machines, which
18289 caused (substring ...) to crash on large vectors (Bug#8344).
18290 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
18291 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
18292 All variadic functions and their callers changed accordingly.
18293 (struct gcpro.nvars): Now size_t, not int. All uses changed.

18295 * editfns.c (general_insert_function): Likewise.
18296 * eval.c (struct backtrace.nargs, interactive_p)
18297 (internal_condition_case_n, run_hook_with_args, apply_lambda)
18298 (funcall_lambda, mark_backtrace): Likewise.
18299 * fns.c (concat): Likewise.
18300 * frame.c (x_set_frame_parameters): Likewise.
18301 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
18302 0 if not found, not -1. All callers changed.
18304 * alloc.c (garbage_collect): Don't assume stack size fits in int.
18305 (stack_copy_size): Now size_t, not int.
18306 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.

18315 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
18316 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

18326 * keyboard.c (safe_run_hook_funcall): New function.
18327 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
18328 don't set the hook to nil, but remove the offending function instead.
18329 (Qcommand_hook_internal): Remove, unused.
18330 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
18331 Vcommand_hook_internal.
18333 * eval.c (enum run_hooks_condition): Remove.
18334 (funcall_nil, funcall_not): New functions.
18335 (run_hook_with_args): Call each function through a `funcall' argument.

18345 * print.c (strout): Remove parameter `multibyte', unused since
18346 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
18348 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
18349 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
18350 All callers changed.
18352 * w32.c (_wsa_errlist): Use braces for struct initializers.

18362 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
18363 All callers changed.
18365 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
18367 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.

18378 (syms_of_nsterm): DEFVAR ns-auto-hide-menu-bar, init to Qnil.
18380 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>

18393 2011-03-26 Eli Zaretskii <eliz@gnu.org>
18395 * xdisp.c (redisplay_window): Don't check buffer's clip_changed
18396 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
18398 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
18400 * w32.c (read_unc_volume): Use parameter `henum', instead of
18401 global variable `wget_enum_handle'.
18403 * keymap.c (describe_vector): Remove parameters `indices' and
18404 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.

18499 2011-03-23 Julien Danjou <julien@danjou.info>
18501 * term.c (Fsuspend_tty, Fresume_tty):
18502 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
18503 * window.c (temp_output_buffer_show):

18510 * callint.c (Fcall_interactively):
18511 * buffer.c (Fkill_all_local_variables):
18512 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
18514 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
18515 unconditionally since it does the check itself.
18517 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
18519 Fix more problems found by GCC 4.5.2's static checks.
18521 * coding.c (encode_coding_raw_text): Avoid unnecessary test
18522 the first time through the loop, since we know p0 < p1 then.
18523 This also avoids a gcc -Wstrict-overflow warning.
18525 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
18526 leading to a memory leak, possible in functions like
18527 load_charset_map_from_file that can allocate an unbounded number
18528 of objects (Bug#8318).
18530 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
18531 that could (at least in theory) be that large.
18533 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
18534 This is less likely to overflow, and avoids undefined behavior if
18535 overflow does occur. All callers changed. Use strtoul to scan
18536 for the unsigned long integer.
18537 (pint2hrstr): Simplify and tune code slightly.
18538 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

18548 * fileio.c (Fcopy_file): Report error if fchown or fchmod
18551 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
18553 * process.c (Fmake_network_process): Use socklen_t, not int,
18554 where POSIX says socklen_t is required in portable programs.
18555 This fixes a porting bug on hosts like 64-bit HP-UX, where
18556 socklen_t is wider than int (Bug#8277).
18557 (Fmake_network_process, server_accept_connection):
18558 (wait_reading_process_output, read_process_output):
18561 * process.c: Rename or move locals to avoid shadowing.

18568 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
18569 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
18571 Make tparam.h and terminfo.c consistent.
18572 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
18573 Include tparam.h instead, since it declares them.
18574 * cm.h (PC): Remove extern decl; tparam.h now does this.
18575 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
18576 * terminfo.c: Include tparam.h, to check interfaces.
18577 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
18578 (tparam): Adjust signature to match interface in tparam.h;
18579 this removes some undefined behavior. Check that outstring and len
18580 are zero, which they always are with Emacs.
18581 * tparam.h (PC, BC, UP): New extern decls.
18583 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
18584 (xftfont_open): Rename locals to avoid shadowing.
18586 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
18587 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.

18589 (ftfont_list): Remove unused local.
18590 (get_adstyle_property, ftfont_pattern_entity):
18591 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
18592 Rename locals to avoid shadowing.
18594 * xfont.c (xfont_list_family): Mark var as initialized.
18596 * xml.c (make_dom): Now static.
18598 * composite.c (composition_compute_stop_pos): Rename local to
18600 (composition_reseat_it): Remove unused locals.
18601 (find_automatic_composition, composition_adjust_point): Likewise.
18602 (composition_update_it): Mark var as initialized.
18603 (find_automatic_composition): Mark vars as initialized,
18604 with a FIXME (Bug#8290).
18606 character.h: Rename locals to avoid shadowing.
18607 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
18608 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
18609 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
18610 (BUF_DEC_POS): Be more systematic about renaming local temporaries
18611 to avoid shadowing.
18613 * textprop.c (property_change_between_p): Remove; unused.
18615 * intervals.c (interval_start_pos): Now static.
18617 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".
18619 * atimer.c (start_atimer, append_atimer_lists, set_alarm):
18620 Rename locals to avoid shadowing.
18622 * sound.c (wav_play, au_play, Fplay_sound_internal):
18623 Fix pointer signedness.
18624 (alsa_choose_format): Remove unused local var.
18625 (wav_play): Initialize a variable to 0, to prevent undefined
18626 behavior (Bug#8278).
18628 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
18630 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
18632 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
18633 clobbering (Bug#8298).
18634 * sysdep.c (sys_subshell): Likewise.
18635 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
18637 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
18638 This should get cleaned up, so that child_setup has the
18639 same signature on all platforms.
18641 * callproc.c (call_process_cleanup): Now static.
18642 (relocate_fd): Rename locals to avoid shadowing.
18644 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
18646 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
18647 not to be necessary, and produces flickering.
18649 2011-03-20 Glenn Morris <rgm@gnu.org>
18651 * config.in: Remove file.
18653 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
18655 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
18656 are now in src/globals.h.
18657 (syms_of_minibuf): Remove spurious & from previous change.

18674 2011-03-17 Eli Zaretskii <eliz@gnu.org>
18676 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.

18683 (sigchld_handler): Now static.
18685 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
18686 That way, the code declares only the vars that it needs.
18687 * s/aix4-2.h (PTY_ITERATION): Declare iteration vars.
18688 * s/cygwin.h (PTY_ITERATION): Likewise.
18689 * s/darwin.h (PTY_ITERATION): Likewise.

18692 * s/irix6-5.h (PTY_OPEN): Declare stb, to loosen coupling.
18693 * process.c (allocate_pty): Don't declare stb unless it's needed.
18695 * bytecode.c (MAYBE_GC): Rewrite so as not to use empty "else".
18696 (CONSTANTLIM): Remove; unused.
18697 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
18698 Define only if needed.
18700 * unexelf.c (unexec): Name an expression,
18701 to avoid gcc -Wbad-function-cast warning.
18702 Use a different way to cause a compilation error if anyone uses
18703 n rather than nn, a way that does not involve shadowing.
18704 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
18706 * deps.mk (unexalpha.o): Remove; unused.
18708 New file unexec.h, the (simple) interface for unexec (Bug#8267).
18709 * unexec.h: New file.
18710 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
18711 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
18712 Depend on unexec.h.
18713 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.

18772 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
18773 some of which prompt warnings from gcc -Wbad-function-cast.
18774 (Fformat_time_string, Fencode_time, Finsert_char):

18803 (Fmemory_limit): Cast sbrk's returned value to char *.
18805 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this

18810 Use functions, not macros, for up- and down-casing (Bug#8254).
18811 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
18812 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
18813 to use the following functions instead of these macros.
18814 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
18815 EMACS_INT, since callers assume the returned value fits in int.
18816 (upcase1): Likewise, for UPCASE_TABLE.
18817 (uppercasep, lowercasep, upcase): New static inline functions.
18818 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

18828 (regex_compile, re_match_2_internal): Mark locals as initialized.
18829 (RETALLOC_IF): Define only if needed.
18830 (WORDCHAR_P): Likewise. This one is never needed, but is used
18831 only in a comment talking about a compiler bug, so put inside
18832 the #if 0 of that comment.
18833 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
18834 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

18861 New macros, so that the caller can use some names other than
18862 gcpro1, gcpro2, etc.
18863 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
18865 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
18866 argument, for consistency with GCPRO2_VAR, etc: it is now the
18867 prefix of the variable, not the variable itself. All uses
18869 * dired.c (directory_files_internal, file_name_completion):
18870 Rename locals to avoid shadowing.
18872 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
18873 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
18874 dired.c's scmp function, had undefined behavior.
18875 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
18876 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
18877 * buffer.h: ... to here, because these macros use current_buffer,
18878 and the new implementation with inline functions needs to have
18879 current_buffer in scope now, rather than later when the macros
18881 (downcase, upcase1): New static inline functions.
18882 (DOWNCASE, UPCASE1): Reimplement using these functions.
18883 This avoids undefined behavior in expressions like
18884 DOWNCASE (x) == DOWNCASE (y), which previously suffered
18885 from race conditions in accessing the global variables
18886 case_temp1 and case_temp2.
18887 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
18888 * lisp.h (case_temp1, case_temp2): Remove their decls.
18889 * character.h (ASCII_CHAR_P): Move from here ...
18890 * lisp.h: ... to here, so that the inline functions mentioned
18891 above can use them.

18895 * fileio.c (file_name_as_directory, directory_file_name):

18898 (file_name_as_directory): Use const pointers when appropriate.
18899 (Fexpand_file_name): Likewise. In particular, newdir might
18900 point at constant storage, so make it a const pointer.

18902 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
18904 (Fset_file_times, Finsert_file_contents, auto_save_error):

18909 to avoid shadowing.
18911 * marker.c (bytepos_to_charpos): Remove; unused.
18913 * lisp.h (verify_bytepos, count_markers): New decls,
18914 so that gcc does not warn that these functions aren't declared.
18916 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
18917 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
18918 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
18919 (copy_text): Remove unused local var.

18922 (lock_file_1): Rename local to avoid shadowing.
18924 * buffer.c (fix_overlays_before): Mark locals as initialized.
18925 (fix_start_end_in_overlays): Likewise. This function should be
18926 simplified by using pointers-to-pointers, but that's a different
18928 (switch_to_buffer_1): Now static.
18929 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
18930 (report_overlay_modification): Rename locals to avoid shadowing.

18933 Fix pointer signedness issue.
18934 (sys_subshell): Mark local as volatile if checking for lint,
18935 to suppress a gcc -Wclobbered warning that does not seem to be right.
18936 (MAXPATHLEN): Define only if needed.
18938 * process.c (serial_open, serial_configure): Move decls from here ...
18939 * systty.h: ... to here, so that they can be checked.
18941 * fns.c (get_random, seed_random): Move extern decls from here ...
18942 * lisp.h: ... to here, so that they can be checked.
18944 * sysdep.c (reset_io): Now static.

18953 (describe_map_tree):
18954 Rename locals to avoid shadowing.

19103 For example, without this patch (encode-time 0 0 0 1 1
19104 1152921504606846976) returns the obviously-bogus value (-948597
19105 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
19106 reports time overflow. See
