1 2012-11-23 Eli Zaretskii <eliz@gnu.org>
3 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
4 between bpos_covered and bpos_max. This fixes cursor display when
5 several display strings follow each other.
7 * .gdbinit (pgx): If the glyph's object is a string, display the
8 pointer to string data, rather than the value of the string object
9 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
11 2012-11-21 Eli Zaretskii <eliz@gnu.org>
13 * indent.c (Fvertical_motion): If the starting position is covered
14 by a display string, return to one position before that, to avoid
15 overshooting it inside move_it_to. (Bug#12930)
17 2012-11-20 Daniel Colascione <dancol@dancol.org>
19 * w32fns.c (Fx_file_dialog):
20 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
21 cygwin_convert_file_name*.
23 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
24 Rename cygwin_convert_path* to cygwin_convert_file_name*.
26 2012-11-20 Ken Brown <kbrown@cornell.edu>
28 * emacs.c (main): Set the G_SLICE environment variable for all
29 Cygwin builds, not just GTK builds. See
30 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
32 2012-11-19 Eli Zaretskii <eliz@gnu.org>
34 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Don't mix declaration of
35 w32_note_current_window with code. (Backport from trunk.)
37 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
38 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
39 Define for the MSVC compiler.
41 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing
44 2012-11-18 Eli Zaretskii <eliz@gnu.org>
46 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
47 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
48 dostounix_filename. Prevents crashes down the road, because
49 dostounix_filename assumes it gets a unibyte string. Reported by
50 Michel de Ruiter <michel@sentient.nl>, see
51 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html
53 2012-11-17 Eli Zaretskii <eliz@gnu.org>
55 * w32select.c: Include w32common.h before w32term.h, so that
56 windows.h gets included before w32term.h uses some of its
59 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]: New
61 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]: New
63 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
65 2012-11-17 Jan Djärv <jan.h.d@swipnet.se>
67 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
68 (ns_select): Return at once if events are held (Bug#12834).
70 2012-11-16 enami tsugutomo <tsugutomo.enami@jp.sony.com>
72 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
73 Needed following 2012-10-20 change. (Bug#12902)
75 2012-11-16 Glenn Morris <rgm@gnu.org>
77 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
79 2012-11-15 Stefan Monnier <monnier@iro.umontreal.ca>
81 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
83 2012-11-14 Eli Zaretskii <eliz@gnu.org>
85 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
86 use the same value of thread handle.
87 (start_timer_thread): If the timer thread exited (due to error),
88 clean up by closing the two handles it used. Duplicate the caller
89 thread's handle here, so it gets duplicated only once, when
90 launching the timer thread. Set priority of the timer thread, not
92 (getitimer): Don't duplicate the caller thread's handle here.
95 2012-11-13 Jan Djärv <jan.h.d@swipnet.se>
97 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
100 2012-11-12 Eli Zaretskii <eliz@gnu.org>
102 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
103 passed to pint2str and pint2hrstr to be at most the size of the
104 frame's decode_mode_spec_buffer. This avoids crashes with very
105 large values of FIELD_WIDTH argument to decode_mode_spec.
108 2012-11-07 Martin Rudalics <rudalics@gmx.at>
110 * window.c (Fsplit_window_internal): Set combination limit of
111 new parent window to t iff Vwindow_combination_limit is t;
112 fixing a regression introduced with the change from 2012-09-22.
113 (Fwindow_combination_limit, Fset_window_combination_limit):
116 2012-11-06 Eli Zaretskii <eliz@gnu.org>
118 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
119 amount when the scroll margins are too large. When scrolling
120 backwards in the buffer, give up if cannot reach point or the
121 scroll margin within a reasonable number of screen lines.
122 Fixes point position in window under scroll-up/down-aggressively when
123 point is positioned many lines beyond the window top/bottom.
126 2012-11-05 Eli Zaretskii <eliz@gnu.org>
128 * ralloc.c (relinquish): If real_morecore fails to return memory
129 to the system, don't crash; instead, leave the last heap
130 unchanged and return. (Bug#12774)
132 2012-11-03 Eli Zaretskii <eliz@gnu.org>
134 * lisp.mk: Adjust comments to the fact that term/internal is now
135 loaded from loadup.el.
137 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
138 (msdos_fatal_signal): New function.
139 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
142 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
143 for GCC versions before 4.
144 (emacs_raise): Define to call msdos_fatal_signal.
146 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
147 iterator when starting in the middle of a display or overlay
150 2012-11-03 Jan Djärv <jan.h.d@swipnet.se>
152 * widget.c (resize_cb): New function.
153 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
154 (EmacsFrameResize): Check if all is up to date before changing frame
157 2012-11-01 Eli Zaretskii <eliz@gnu.org>
159 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
161 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
163 Fix crash when using Emacs as commit editor for git (Bug#12697).
164 * callproc.c (setpgrp): Remove macro, as we now use setpgid
165 and it is configured in conf_post.h.
166 (Fcall_process): Don't invoke both setsid and setpgid; the former
167 is enough, if it exists.
168 * callproc.c (Fcall_process, child_setup):
169 * process.c (create_process): Use setpgid.
170 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
172 * dispnew.c (init_display): Initialize the foreground group
173 if we are running a tty display.
174 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
175 * lisp.h (init_foreground_group): New decl.
176 * sysdep.c (inherited_pgroup): New static var.
177 (init_foreground_group, tcsetpgrp_without_stopping)
178 (narrow_foreground_group, widen_foreground_group): New functions.
179 (init_sys_modes): Narrow foreground group.
180 (reset_sys_modes): Widen foreground group.
182 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
184 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
186 2012-10-31 Martin Rudalics <rudalics@gmx.at>
188 * minibuf.c (read_minibuf): Restore current buffer since
189 choose_minibuf_frame calling Fset_frame_selected_window may
190 change it (Bug#12766).
192 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
194 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
196 2012-10-30 Kenichi Handa <handa@gnu.org>
198 * font.c (Ffont_at): If WINDOW is specified and it is not
199 displaying the current buffer, signal an error.
201 2012-10-29 Daniel Colascione <dancol@dancol.org>
203 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
204 In preparation for fixing bug#12739, move these functions from
207 * coding.h, coding.c: ... to here, and compile them only when
208 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
209 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
211 2012-10-28 Eli Zaretskii <eliz@gnu.org>
213 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
214 (timer_loop, getitimer, setitimer): Use it instead of
215 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
217 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
220 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
222 * nsterm.m (NO_APPDEFINED_DATA): New define.
223 (last_appdefined_event_data): New variable
224 (last_appdefined_event): Remove.
225 (ns_select): Initialize t from last_appdefined_event_data instead
226 of [last_appdefined_event data1].
227 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
228 remove last_appdefined_event (Bug#12698).
230 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
232 * frame.c (x_set_font): Catch internal error.
234 2012-10-27 Eli Zaretskii <eliz@gnu.org>
236 Avoid overflow in w32 implementation of interval timers.
237 When possible, for ITIMER_PROF count only times the main thread
239 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
240 'volatile ULONGLONG' types. All the other data which was
241 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
242 (GetThreadTimes_Proc): New typedef.
243 (w32_get_timer_time): New function, returns a suitable time value
245 (timer_loop): Enter critical section when accessing ULONGLONG
246 values of the itimer_data struct, as these accesses are no longer
247 atomic. Call 'w32_get_timer_time' instead of 'clock'.
248 Remove unused variable.
249 (init_timers): Initialize s_pfn_Get_Thread_Times.
250 (start_timer_thread): Don't assign itimer->caller_thread here.
251 (getitimer): Assign itimer->caller_thread here.
252 (setitimer): Always call getitimer to get the value of ticks_now.
253 (sys_spawnve): Avoid compiler warning about format mismatch.
255 2012-10-26 Eli Zaretskii <eliz@gnu.org>
257 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
258 mouse movement events if the menu bar is active. This avoids
259 producing a busy "hour-glass" cursor by Windows if the mouse
260 pointer is positioned over a tooltip shown for some menu item.
262 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
264 Don't assume process IDs fit in int.
265 * emacs.c (shut_down_emacs) [!DOS_NT]:
266 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
267 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
268 Use pid_t, not int, to store process IDs, as 'int'
269 is not wide enough on a few platforms (e.g., AIX and IRIX).
271 2012-10-23 Kenichi Handa <handa@gnu.org>
273 The following change is to make face-font-rescale-alist work
274 correctly for non-ASCII fonts.
276 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
277 (font_open_for_lface): Handle Vface_font_rescale_alist.
279 2012-10-23 Chong Yidong <cyd@gnu.org>
281 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
283 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>
285 * nsfont.m (nsfont_open, ns_glyph_metrics): Force integer advancement
287 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
289 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
292 2012-10-21 Glenn Morris <rgm@gnu.org>
294 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
296 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
299 * frame.c (Fmouse_position, Fmouse_pixel_position):
300 * xdisp.c (produce_stretch_glyph):
301 Declare local vars only when they're needed.
302 This is clearer and avoids a warning on OpenBSD about unused vars.
303 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
304 This is safer, and avoids OpenBSD warnings about unused vars.
305 * keyboard.c (record_menu_key): Remove unnecessary decl.
306 (poll_timer): Define only if POLL_FOR_INPUT is defined.
307 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
308 as our definition clashes with OpenBSD's.
309 * xfaces.c (load_face_colors, check_lface_attrs)
310 (get_lface_attributes_no_remap, get_lface_attributes)
311 (lface_fully_specified_p, x_supports_face_attributes_p)
312 (tty_supports_face_attributes_p, face_fontset, realize_face)
313 (realize_x_face, realize_tty_face):
314 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
315 merely Lisp_Object *. This is more informative and avoids
316 a warning on OpenBSD about accessing beyond an object's size.
318 2012-10-20 Chong Yidong <cyd@gnu.org>
320 * lread.c (Fload): Doc fix (Bug#12592).

324 * font.c (Ffont_at): Fix previous change.
326 2012-10-19 Eli Zaretskii <eliz@gnu.org>
328 * puresize.h (BASE_PURESIZE): Bump the base value to 1700000.
329 See http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00593.html
332 * alloc.c (NSTATICS): Decrease to 0x800.
334 2012-10-19 Stefan Monnier <monnier@iro.umontreal.ca>

339 2012-10-18 Jan Djärv <jan.h.d@swipnet.se>
341 * nsterm.m (ns_select): Check writefds before call to
342 FD_ISSET (Bug#12668).
344 2012-10-18 Daniel Colascione <dancol@dancol.org>
346 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
347 (staticpro): If we run out of staticpro slots, die with an
348 informative error instead of just calling emacs_abort.
350 2012-10-18 Martin Rudalics <rudalics@gmx.at>
352 Fix two flaws reported by Dmitry Antipov.
353 * window.c (Ftemp_output_buffer_show): Remove.

394 (Fcygwin_convert_path_from_windows): Use EQ to compare 2
395 Lisp_Object values. (Bug#12661)
397 * w32fns.c (w32_msg_pump): Use XIL instead of casting an integer
398 to Lisp_Object. (Bug#12661)
400 2012-10-17 Kenichi Handa <handa@gnu.org>
402 * xdisp.c (reseat_1): Make the information stored in it->cmp_it

439 Set windows_or_buffers_changed.
441 2012-10-15 Daniel Colascione <dancol@dancol.org>
443 * dbusbind.c: Fix cygw32 build break when compiling with dbus
444 enabled by undefining the symbol "interface", which the platform
445 headers define to something incompatible.
447 2012-10-14 Daniel Colascione <dancol@dancol.org>
449 * image.c (init_tiff_functions, init_imagemagick_functions)
450 (init_svg_functions): Fix cygw32 build break by using these
451 functions only when WINDOWSNT _and_ HAVE_NTGUI.

478 rather than stat + fopen.
479 (pbm_read_file) [0]: Remove unused code with stat race.
480 * process.c (allocate_pty) [HAVE_PTYS && !PTY_ITERATION && !PTY_OPEN]:
481 Remove ineffective code with stat race.
483 2012-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
485 * doc.c (get_doc_string): Don't signal an error if the file is missing.
487 2012-10-12 Jan Djärv <jan.h.d@swipnet.se>
489 * nsterm.m (hold_event_q): New static variable.

506 * fileio.c (check_existing): New function.
507 (make_temp_name, Ffile_exists_p, Ffile_writable_p): Call it
508 instead of calling 'stat', when what's needed is to check whether
509 a file exists. This avoids expensive system calls on MS-Windows.
512 * w32.c (init_environment): Call 'check_existing' instead of 'stat'.
514 * lread.c (openp) [WINDOWSNT]: Call 'access' instead of 'stat' to

553 as it's not a predicate. All uses changed. Omit unnecessary
556 2012-10-11 Dmitry Antipov <dmantipov@yandex.ru>
558 * editfns.c (save_excursion_save): Use nil if mark points to nowhere.

602 Use bool for boolean.
603 * keyboard.c (timers_run, swallow_events)
604 (detect_input_pending_run_timers):
605 * process.c (wait_reading_process_output):
606 Use unsigned for counter where wraparound-on-overflow is desired,
607 since unsigned is guaranteed to have that behavior and signed is not.
608 (read_char): Use ptrdiff_t for string length.
609 (get_input_pending): Remove first argument, since it was always
610 the same pointer-to-int (now pointer-to-boolean) &input_pending,
611 and behave as if it had that value. Return new value of
612 input_pending. All callers changed.
613 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
614 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's

619 * regex.c (immediate_quit) [emacs]: Remove duplicate decl.
621 2012-10-10 Juanma Barranquero <lekktu@gmail.com>

630 initializer for PVEC_NORMAL_VECTOR.
632 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
634 Clean out old termopts cruft.
635 * termopts.h (flow_control, meta_key): Remove unused decls.
636 * dispnew.c, indent.c, nsterm.m, term.c, xsettings.c, xsmfns.c:
637 Don't include termopts.h.
639 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>
641 * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers.
643 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>

652 (syms_of_nsfont): Remove initialization of Vfonts_in_cache.
654 2012-10-09 Eli Zaretskii <eliz@gnu.org>
656 * w32fns.c (w32_last_error): Change the return value to DWORD, to
657 match what GetLastError returns. Explain why the function is
660 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
661 'is_tooltip_frame', to avoid confusion with its global namesake.
663 2012-10-08 Daniel Colascione <dancol@dancol.org>
665 * xdisp.c (start_hourglass): Call w32_note_current_window when
666 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
667 build that caused Emacs to display the hourglass cursor forever.
669 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
670 which is broken under remote desktop, calculate the number of
671 colors available for a display based on the display's number of
672 planes and number of bits per pixel per plane. (bug#10397).
674 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
676 * nsfont.m (Vfonts_in_cache): New variable.
677 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
678 are used. Add cached fonts to Vfonts_in_cache.
679 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
681 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
683 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
685 (FONT_H): Define after FRAME_H.
686 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
689 * w32term.c: Remove leftover declaration of keyboard_codepage.
691 2012-10-08 Eli Zaretskii <eliz@gnu.org>
693 * makefile.w32-in (FONT_H): Add $(FRAME_H).
694 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
695 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
696 (GLOBAL_SOURCES): Add cygw32.c.
697 ($(BLD)/unexw32.$(O)):
699 ($(BLD)/w32console.$(O)):
700 ($(BLD)/w32fns.$(O)):
701 ($(BLD)/w32heap.$(O)):
702 ($(BLD)/w32menu.$(O)):
703 ($(BLD)/w32proc.$(O)): Add w32common.h.
705 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
707 (x_to_w32_color): Don't modify the argument, modify a copy instead.
709 2012-10-08 Daniel Colascione <dancol@dancol.org>
711 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
712 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
713 accidental message numbering hole. Change other messages to
716 * w32select.h (HAVE_W32SELECT): Remove.
718 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
719 w32common.h instead of w32heap.h.
721 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
722 (get_allocation_unit, get_processor_type, get_w32_major_version)
723 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
724 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
725 (OS_NT, os_subtype, cache_system_info): Move declarations to
728 * w32heap.c: Include w32common.h.
729 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
730 (w32_minor_version, w32_build_number, w32_subtype):
731 Remove duplicate definitions.
733 * w32fns.c: Include w32common.h; include w32heap.h only in
736 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
737 Use `report_file_error' instead of `error' in order to better
738 inform users of what went wrong. Increase NTGUI_UNICODE file
739 dialog box file name length to 32k, the maximum allowed by the NT
742 * w32common.h: New file.
743 (ROUND_UP, ROUND_DOWN, get_page_size)
744 (get_allocation_unit, get_processor_type, get_w32_major_version)
745 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
746 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
747 (OS_NT, os_subtype, cache_system_info): Move here.
749 * unexw32.c, unexcw.c: Include w32common.h.
751 * emacs.c (main): Use (defined (WINDOWSNT) || defined
752 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
753 to call syms_of_w32select.
755 * cygw32.h: Remove obsolete EXFUN declarations.
757 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
759 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
760 of w32inevt.o from SOME_MACHINE_OBJECTS.
762 2012-10-08 Daniel Colascione <dancol@dancol.org>
764 * image.c: Permanent fix for JPEG compilation issue --- limit
765 jpeglib `boolean' redefinition to Cygwin builds.
767 2012-10-08 Eli Zaretskii <eliz@gnu.org>
769 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
771 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
774 2012-10-08 Daniel Colascione <dancol@dancol.org>
776 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
777 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
778 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
779 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
780 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
781 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
782 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
783 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
784 now a supported configuration.
786 * Makefile.in: consolidate image variables into LIBIMAGE; add
787 W32_OBJ and W32_LIBS. Compile new files.
790 (_DebPrint) declare tracing facility for W32 debugging. We need
791 to unify tracing later.
793 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
794 unconditional use of W32 Unicode functions. Cygwin runs only on
795 100% Unicode operating systems.
797 * cygw32.c: New file. Define Cygwin-specific facilities.
798 (Fcygwin_convert_path_to_windows)
799 (Fcygwin_convert_path_from_windows): New user functions for
800 accessing Cygwin path-munging routines.
802 * cygw32.h: New file.
803 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
804 UTF-16LE strings temporarily inside non-Lisp-visible string
807 (w32_strerror): Just what it says on the tin.
809 * emacs.c: Make the NS fork-then-exec code for daemon-launching
810 also run for Cygwin; both systems have the same problem with using
811 GUI facilities in a forked child. Also call syms_of_cygw32,
812 syms_of_w32select in correct places.
814 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
815 needs fork-then-exec for daemon launching.
817 * font.h: Include frame.h.
819 * image.c: Use the image library cache machinery only when we're
820 compiling for native WINDOWSNT; Cygwin can use shared libraries
821 like any other Unixlike system.
823 * keyboard.c: Clarify a comment regarding the input loop.
825 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
826 functions directly instead of trying to detect at runtime that our
827 host operating system supports them. We make this change for two
828 reasons: Cygwin lacks support for the multibyte character
829 conversion functions used by the legacy menu code, and Cygwin
830 never needs to rely on non-Unicode APIs.
832 * unexw32.c (hinst): Declare extern.
834 * w32.c: Change header order;
835 (w32_strerror): Move to w32fns.c because we need it for
836 non-WINDOWSNT builds.
838 * w32.h: Add #error macro to make sure we don't include w32.h for
839 Cygwin builds. Remove w32select declarations.
841 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
842 w32fns.c. w32console.c is WINDOWSNT-only.
844 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
845 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
847 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
848 (w32_major_version, w32_minor_version, w32_build_number)
849 (os_subtype, sound_type): Define here
850 (w32_defined_color): Make color parameter const for consistency
851 with other _defined_color functions.
852 (w32_createwindow): Unconditionally call w32_init_class instead of
853 doing so only when hprevinst is non-NULL. Plumbing hprevinst
854 through the code is complex and unnecessary because class
855 registration is practically free.
856 (w32_name_of_message): New EMACSDEBUG-only function.
857 (Fset_message_beep): Move here
858 (Fx_open_connection): Require that the display name for Windows be
859 "w32" for consistency, emacsclient disambiguation, and maybe, one
860 day, multi-window-system support.
861 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
862 Cygwin files for W32 GUI facilities, since these clearly don't
865 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
866 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
867 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
868 (w32_last_error): Remove.
870 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
872 * w32heap.c (syspage_mask): Declare here.
873 (cache_system_info): Remove.
875 * w32inevt.c (faked_key): Define globally, not statically.
876 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
877 (w32_console_toggle_lock_key): Move to w32fns.c.
879 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
881 * w32proc.c (_DebPrint): Move to w32fns.c.
882 * w32select.c: Include string.h, stdio.h for Cygwin.
883 * w32select.h: New File.
885 * w32term.c: Include io.h for non-CYGWIN builds; needed for
887 (w32_message_fd): New variable. Under Cygwin, holds the file
888 descriptor the system used to tell us about pending thread
891 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
892 that prevented compilation under non-WINDOWSNT systems.
894 (w32_initialize): Open /dev/windows and assign it to
895 w32_message_fd. Provide w32 feature.
897 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
898 (WM_EMACS_INPUT_READY): add.
899 (prepend_msg, w32_message_fd): Declare globally.
902 (keyboard_handle): Use only when WINDOWSNT.
903 (notify_msg_ready): New function. Posts a message to the main
904 thread's message queue under CYGWIN, which wakes up the main
905 thread from select(2) by making the /dev/windows file descriptor
906 ready. Under WINDOWSNT, it sets an event the same way the old
909 (post, prepend_msg): Actually call notify_msg_ready instead of
910 setting the input event directly.
912 2012-10-07 Eli Zaretskii <eliz@gnu.org>
914 * ralloc.c (relinquish): If a heap is ready to be relinquished,
915 but it still has blocs in it, don't return it to the system,
916 instead of aborting. (Bug#12402)
918 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
920 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
922 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
923 MAC_OS_X_VERSION_10_6.

933 * nsmenu.m (fillWithWidgetValue:): Remove code for <
934 MAC_OS_X_VERSION_10_2.
936 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.

939 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
941 * nsterm.m (ns_in_resize): Remove (Bug#12479).
942 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
943 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
944 Remove ns_in_resize check.
945 (ns_clear_frame_area): Remove resize handle code.
947 * nsfns.m (ns_in_resize): Remove.
948 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
949 Remove ns_in_resize check.
951 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
953 Improve sys_siglist detection.
954 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
955 defined as a macro, as is done in Solaris.
956 (sys_siglist_entries): New macro.
957 (save_strsignal): Use it.
958 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
959 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
961 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
963 * nsfns.m (Fx_create_frame): Call x_default_parameter with
964 fullscreen/Fullscreen.

969 * nsterm.m (x_make_frame_visible): Check for fullscreen.
970 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
971 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
972 (windowDidResize:): Check for correct window if old style fullscreen.
973 Capitalize word in comment. Remove incorrect comment.
974 (initFrameFromEmacs:): tbar_height renamed tibar_height.
975 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
976 error in drawing background.
977 (toggleFullScreen:): Remove comment. Rearrange calls.
978 Set toolbar values to zero, save old height in tobar_height.
979 Restore tool bar height when leaving fullscreen.
980 (canBecomeMainWindow): New function.

986 2012-10-05 Eli Zaretskii <eliz@gnu.org>
988 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
990 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
991 that time stamps of directories could also be changed.
992 Don't request the too broad GENERIC_WRITE, only the more restrictive
993 FILE_WRITE_ATTRIBUTES access rights.
995 * fileio.c (Fset_file_times): Special-case ignoring errors for
996 directories only on MSDOS, not on MS-Windows.
998 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
1000 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
1002 2012-10-04 Eli Zaretskii <eliz@gnu.org>
1004 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
1005 see whether CreateFile failed.
1007 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
1009 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
1010 to avoid similar races.
1011 * keyboard.c (pending_signals): Now bool, not int.
1013 Port timers to OpenBSD, plus check for timer failures.
1014 OpenBSD problem reported by Han Boetes.
1015 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
1017 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
1018 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
1019 like OpenBSD, which has timer_settime but does not declare it.
1020 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
1021 whether to use itimerspec-related primitives. All uses of
1022 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
1024 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
1026 * profiler.c (handle_profiler_signal): Fix a malloc race
1027 that caused Emacs to hang on Fedora 17 when profiling Lisp.
1029 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
1031 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
1033 2012-10-02 Eli Zaretskii <eliz@gnu.org>
1035 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
1036 consistent with the change in return value of 'safe_strsignal'.
1038 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
1040 Prefer plain 'static' to 'static inline' (Bug#12541).
1041 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
1042 (bidi_set_sor_type, bidi_push_embedding_level)
1043 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
1044 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)

1048 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
1049 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
1050 Now 'static', not 'static inline'.
1052 Count overruns when profiling; change units to ns.
1053 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
1054 Give extra weight to samples after overruns, to attempt to count
1055 the time more accurately.
1056 (setup_cpu_timer): Change sampling interval units from ms to ns, since
1057 the underlying primitives nominally do ns.
1058 (Fprofiler_cpu_start): Document the change. Mention that
1059 the sampling intervals are only approximate.
1061 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
1063 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
1065 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
1066 case for the special 0 coding-system.
1068 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
1069 (Fmake_overlay): Remove redundant tests.
1070 (fix_start_end_in_overlays): Remove redundant recentering.
1072 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
1074 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
1075 Update dependencies.
1077 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
1079 Fix a malloc race condition involving strsignal.
1080 A signal can arrive in the middle of a malloc, and Emacs's signal
1081 handler can invoke strsignal, which can invoke malloc, which is
1082 not portable. This race condition bug makes Emacs hang on GNU/Linux.
1083 Fix it by altering the signal handler so that it does not invoke
1085 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
1086 * process.c (status_message): Use const pointer, in case strsignal
1087 is #defined to safe_strsignal.
1088 * sysdep.c (sys_siglist, init_signals): Always define and
1089 initialize a substitute sys_siglist if the system does not define
1090 one, even if HAVE_STRSIGNAL.
1091 (safe_strsignal): Rename from strsignal. Always define,
1092 using sys_siglist. Return a const pointer.
1093 * syssignal.h (safe_strsignal): New decl.
1094 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
1096 2012-10-01 Eli Zaretskii <eliz@gnu.org>
1098 * w32proc.c (timer_loop): Fix code that waits for timer
1099 expiration, to avoid high CPU usage.
1101 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
1103 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
1104 (sweep_weak_table): Remove redundant prototypes.
1106 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
1108 * emacs.c: Move the inclusion of TERM_HEADER after including
1109 windows.h on WINDOWSNT. This avoids compilation problems with
1112 2012-10-01 Eli Zaretskii <eliz@gnu.org>
1114 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
1115 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
1116 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
1117 as the previous version used 'void *'.
1119 * ralloc.c (ROUNDUP): Fix last change.
1120 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
1123 * w32proc.c <disable_itimers>: New static flag.
1124 (init_timers): Initialize it to zero, after creating the critical
1125 sections used by the timer threads.
1126 (term_timers): Set to 1 before deleting the critical sections.
1127 (getitimer, setitimer): If disable_itimers is non-zero, return an
1128 error indication without doing anything. Reported by Fabrice
1129 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
1130 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
1132 [!HAVE_SETITIMER]: Behave as the previous version that didn't
1135 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
1136 term_ntproc after all the other bookkeeping, to get timers working
1137 as long as possible.
1139 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
1141 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
1142 Suggested by Juri Linkov in
1143 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
1145 Prefer plain 'static' to 'static inline' (Bug#12541).
1146 With static functions, modern compilers inline pretty well by
1147 themselves; advice from programmers often hurts as much as it helps.
1148 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
1149 this change shrinks the text size of the Emacs executable by 1.1%
1150 without affecting CPU significantly in my benchmark.
1151 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)
1152 (live_float_p, live_misc_p, live_vector_p, live_buffer_p)

1231 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
1233 Revert the FOLLOW-SYMLINKS change for file-attributes.
1234 Doing it right would require several changes to Tramp, and there's
1235 not enough time to get that tested before the freeze today.
1236 * dired.c (directory_files_internal, Ffile_attributes):
1239 * frame.c (x_report_frame_params): Port better to wider ints.

1279 (check_memory_limits): Adjust prototypes of real_morecore and
1280 __morecore to receive argument of type ptrdiff_t. Use size_t for

1364 * w32.h (init_timers, term_timers): Add prototypes.
1366 2012-09-30 Kenichi Handa <handa@gnu.org>
1368 * coding.c (decode_coding_ccl, encode_coding_ccl): Pay attention
1369 to the buffer relocation which may be caused by ccl_driver.

1449 for consistency with other handlers.
1450 (setup_cpu_timer): New function, with much of what used to be in
1451 Fprofiler_cpu_start. Check for out-of-range argument.
1452 Prefer timer_settime if available, and prefer
1453 thread cputime clocks, then process cputime clocks, then
1454 monotonic clocks, to the old realtime clock. Use make_timeval
1455 to round more-correctly when falling back to setitimer.
1456 (Fprofiler_cpu_start): Use it.
1457 (Fprofiler_cpu_stop): Prefer timer_settime if available.
1458 Don't assume that passing NULL as the 2nd argument of setitimer
1459 is the same as passing a pointer to all-zero storage.
1460 Ignore SIGPROF afterwards.
1461 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
1462 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
1463 non-fatal signal handlers. Ignore SIGPROF on startup.
1464 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
1465 in profiler.c, since sysdep.c now uses it.
1467 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.
1468 Suggested by Eli Zaretskii in

1482 (Fbacktrace_frame): Adjust accordingly.
1484 2012-09-28 Glenn Morris <rgm@gnu.org>
1486 * eval.c (Frun_hook_with_args, Frun_hook_with_args_until_success)
1487 (Frun_hook_with_args_until_failure): Doc fixes.
1489 2012-09-28 Eli Zaretskii <eliz@gnu.org>
1491 * xdisp.c (syms_of_xdisp) <Qredisplay_internal>: Rename from

1521 * character.h (MAYBE_UNIFY_CHAR): Remove.
1522 * charset.c, charset.h (maybe_unify_char): Now static.
1523 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
1524 Since this stuff is now private to charset.c, there's no need for
1525 a public macro and no need to inline by hand.

1558 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>
1560 Prefer POSIX timers if available.
1561 They avoid a race if the timer is too close to the current time.
1562 * atimer.c (alarm_timer, alarm_timer_ok) [SIGEV_SIGNAL]: New static vars.
1563 (set_alarm) [SIGEV_SIGNAL]: Use POSIX timers if available.
1564 (init_atimer) [SIGEV_SIGNAL]: Initialize them.
1566 2012-09-25 Eli Zaretskii <eliz@gnu.org>

1589 * w32.h (Vlibrary_cache): Do not declare.
1591 2012-09-25 Eli Zaretskii <eliz@gnu.org>
1593 * w32proc.c (sys_signal): Handle all signals defined by the
1594 MS-Windows runtime, not just SIGCHLD. Actually install the signal
1595 handlers for signals supported by Windows. Don't override
1596 term_ntproc as the handler for SIGABRT.
1597 (sigaction): Rewrite to call sys_signal instead of duplicating its
1599 (sys_kill): Improve commentary.
1601 * w32.c (term_ntproc): Accept (and ignore) one argument, for
1602 consistency with a signature of a signal handler. All callers
1604 (init_ntproc): Accept an argument DUMPING. If dumping, don't
1605 install term_ntproc as a signal handler for SIGABRT, as that
1606 should be done by the dumped Emacs.
1608 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
1610 * w32select.c (term_w32select): Protect against repeated
1611 invocation by setting clipboard_owner to NULL after calling
1614 * emacs.c (shut_down_emacs, main): Adapt the calls to init_ntproc
1615 and term_ntproc to their modified signatures.
1617 * character.c (char_string, string_char): Remove calls to
1618 MAYBE_UNIFY_CHAR. See the discussion starting at

1622 2012-09-25 Chong Yidong <cyd@gnu.org>
1624 * xdisp.c (mode_line_inverse_video): Delete obsolete variable.
1626 2012-09-24 Stefan Monnier <monnier@iro.umontreal.ca>
1628 * bytecode.c (exec_byte_code): Signal an error instead of aborting,
1629 when encountering an unknown bytecode.
1631 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
1633 image.c, indent.c: Use bool for booleans.
1634 * dispextern.h (struct image_type): Members valid_p, load, init
1635 now return bool, not int. All uses changed.
1636 * image.c: Omit unnecessary static decls.
1637 (x_create_bitmap_mask, x_build_heuristic_mask):
1638 Return void, not int, since callers don't care about the return value.

1673 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
1675 Move pid_t related decls out of lisp.h.
1676 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
1677 (interruptible_wait_for_termination):
1678 Move these decls from lisp.h to syswait.h, since they use pid_t.
1679 Needed on FreeBSD; see Herbert J. Skuhra in
1680 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
1681 * callproc.c: Include syswait.h.

1699 * nsmenu.m, w32menu.c, xmenu.c (set_frame_menubar):

1701 Use bool for boolean.
1702 * gtkutil.c (xg_update_frame_menubar):

1727 2012-09-23 Eli Zaretskii <eliz@gnu.org>
1729 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
1730 fatal_error_backtrace.
1732 * w32proc.c (sys_kill): Undo last change: don't do anything when
1733 invoked to deliver SIGABRT to our own process. This is now
1734 handled by emacs_raise.
1736 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
1738 * w32term.c (w32_read_socket): Remove leftover reference to
1739 interrupt_input_pending.
1741 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
1743 Do not use SA_NODEFER.
1744 Problem reported by Dani Moncayo in
1745 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
1747 * sysdep.c (emacs_abort): Do not reset signal handler.
1748 * emacs.c (terminate_due_to_signal): Reset signal handler here.
1749 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
1750 wanted even on POSIXish hosts, and it doesn't work on Windows.
1752 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
1754 * xterm.c (x_term_init): Call fixup_locale before and after calling
1755 gtk_init (Bug#12392).
1757 2012-09-23 Chong Yidong <cyd@gnu.org>
1759 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
1760 Vdynamic_library_alist.
1762 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
1763 (Fgnutls_available_p): Caller changed.
1765 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
1766 (Flibxml_parse_xml_region): Likewise.
1768 * dispextern.h (struct image_type): Remove arg from init function.
1770 * image.c (Finit_image_library, lookup_image_type)
1771 (define_image_type): Remove now-unneeded second arg.
1772 (init_xpm_functions, init_png_functions, init_jpeg_functions)
1773 (init_tiff_functions, init_gif_functions, init_svg_functions):
1774 Arglist and w32_delayed_load calling convention changed.
1775 (gs_type): Remove init_gs_functions; there is no such function.
1776 (valid_image_p, make_image): Fix caller to lookup_image_type.
1778 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
1780 Simplify and avoid signal-handling races (Bug#12471).
1782 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
1783 Avoid recursive loop if there's a fatal error in the function itself.
1784 * atimer.c (pending_atimers):
1785 * blockinput.h: Don't include "atimer.h"; no longer needed.
1786 (interrupt_input_pending): Remove. All uses removed.
1787 pending_signals now counts both atimers and ordinary interrupts.
1788 This is less racy than having three separate pending-signal flags.
1789 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
1791 Rename from their upper-case counterparts BLOCK_INPUT,
1792 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
1793 INPUT_BLOCKED_P, and turn into functions. All uses changed.
1794 This makes it easier to access volatile variables more accurately.
1795 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
1796 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
1797 that's more reliable if the code is buggy and sets
1798 interrupt_input_blocked to a negative value. All uses changed.
1799 * atimer.c (deliver_alarm_signal):
1800 Remove. No need to deliver this to the parent; any thread can
1801 handle this signal now. All uses replaced by underlying handler.
1802 * atimer.c (turn_on_atimers):
1803 * dispnew.c (handle_window_change_signal):
1804 * emacs.c (handle_danger_signal):
1805 * keyboard.c (kbd_buffer_get_event):
1806 Don't reestablish signal handler; not needed with sigaction.
1807 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
1809 Rework to avoid unnecessary accesses to volatile variables.
1810 (UNBLOCK_INPUT_TO): Now a function.
1811 (totally_unblock_input, unblock_input): New decls.
1812 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
1813 (init_data): Remove. Necessary stuff now done in init_signal.
1814 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
1815 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
1816 (fatal_error_code): Remove; no longer needed.
1817 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
1818 it doesn't always backtrace. All uses changed. No need to reset
1819 signal to default, since sigaction and/or die does that for us now.
1820 Use emacs_raise (FOO), not kill (getpid (), FOO).
1821 (main): Check more-accurately whether we're dumping.
1822 Move fatal-error setup to sysdep.c
1823 * floatfns.c: Do not include "syssignal.h"; no longer needed.
1824 * gtkutil.c (xg_get_file_name, xg_get_font):
1825 Remove no-longer-needed signal-mask manipulation.
1826 * keyboard.c, process.c (POLL_FOR_INPUT):
1827 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
1828 * keyboard.c (read_avail_input): Remove.
1829 All uses replaced by gobble_input.
1830 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
1831 (kbd_buffer_store_event_hold, gobble_input):
1832 (record_asynch_buffer_change) [USABLE_SIGIO]:
1833 (store_user_signal_events):
1834 No need to mess with signal mask.
1835 (gobble_input): If blocking input and there are terminals, simply
1836 set pending_signals to 1 and return. All hooks changed to not
1837 worry about whether input is blocked.
1838 (process_pending_signals): Clear pending_signals before processing
1839 them, in case a signal comes in while we're processing.
1840 By convention callers now test pending_signals before calling us.
1841 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
1842 New functions, to support changes to blockinput.h.
1843 (handle_input_available_signal): Now extern.
1844 (reinvoke_input_signal): Remove. All uses replaced by
1846 (quit_count): Now volatile, since a signal handler uses it.
1847 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
1848 All callers changed. Block SIGINT only if not already blocked.
1849 Clear sigmask reliably, even if Fsignal returns, which it can.
1850 Omit unnecessary accesses to volatile var.
1851 (quit_throw_to_read_char): No need to restore sigmask.
1852 * keyboard.c (gobble_input, handle_user_signal):
1853 * process.c (wait_reading_process_output):
1854 Call signal-handling code rather than killing ourselves.
1855 * lisp.h: Include <float.h>, for...
1856 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
1857 (pending_signals): Now volatile.
1858 (syms_of_data): Now const if IEEE floating point.
1859 (handle_input_available_signal) [USABLE_SIGIO]:
1860 (terminate_due_to_signal, record_child_status_change): New decls.
1861 * process.c (create_process): Avoid disaster if memory is exhausted
1862 while we're processing a vfork, by tightening the critical section
1864 (send_process_frame, process_sent_to, handle_pipe_signal)
1865 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
1867 (send_process): No need for setjmp/longjmp any more, since the
1868 SIGPIPE stuff is now gone. Instead, report an error if errno
1870 (record_child_status_change): Now extern. PID and W are now args.
1871 Return void, not bool. All callers changed.
1872 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
1873 Remove. All uses removed. This bug should be fixed now in a
1875 (wait_for_termination_1): Use waitpid rather than sigsuspend,
1876 and record the child status change directly. This avoids the
1877 need to futz with the signal mask.
1878 (process_fatal_action): Move here from emacs.c.
1879 (emacs_sigaction_flags): New function, containing
1880 much of what used to be in emacs_sigaction_init.
1881 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
1882 caught by emacs, to make races less likely.
1883 (deliver_process_signal): Rename from handle_on_main_thread.
1885 (BACKTRACE_LIMIT_MAX): Now at top level.
1886 (thread_backtrace_buffer, threadback_backtrace_pointers):
1888 (deliver_thread_signal, deliver_fatal_thread_signal):
1889 New functions, for more-accurate delivery of thread-specific signals.
1890 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
1891 (deliver_arith_signal): Handle in this thread, not
1892 in the main thread, since it's triggered by this thread.
1893 (maybe_fatal_sig): New function.
1894 (init_signals): New arg DUMPING so that we can be more accurate
1895 about whether we're dumping. Caller changed.
1896 Treat thread-specific signals differently from process-general signals.
1897 Block all signals while handling fatal error; that's safer.
1898 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
1900 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
1901 Ignore SIGPIPE unless batch.
1902 (emacs_backtrace): Output backtrace for the appropriate thread,
1903 which is not necessarily the main thread.
1904 * syssignal.h: Include <stdbool.h>.
1905 (emacs_raise): New macro.
1906 * xterm.c (x_connection_signal): Remove; no longer needed
1907 now that we use sigaction.
1908 (x_connection_closed): No need to mess with sigmask now.
1909 (x_initialize): No need to reset SIGPIPE handler here, since
1910 init_signals does this for us now.
1912 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
1914 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
1915 background rect may be larger (Bug#12245).
1917 2012-09-23 Chong Yidong <cyd@gnu.org>
1919 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
1921 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
1923 * .gdbinit: Just stop at fatal_error_backtrace.
1924 See Stefan Monnier's request in
1925 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
1926 Remove no-longer-used query of system type.
1928 2012-09-22 Chong Yidong <cyd@gnu.org>
1930 * search.c (Freplace_match): Doc fix (Bug#12325).
1932 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
1934 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
1935 (Fline_end_position): Doc fix.
1937 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
1939 2012-09-22 Chong Yidong <cyd@gnu.org>
1941 * dispextern.h (struct image_type): Add new slot, storing a type
1942 initialization function.
1944 * image.c (define_image_type): Call the image initializer function
1945 if it is defined. Arguments and return value changed.
1946 (valid_image_p, make_image): Callers changed.
1947 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
1948 (gif_type, imagemagick_type, svg_type, gs_type):
1949 Add initialization functions.
1950 (Finit_image_library): Call lookup_image_type.
1951 (CHECK_LIB_AVAILABLE): Macro deleted.
1952 (lookup_image_type): Call define_image_type here, rather than via
1953 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
1954 (syms_of_image): Move define_image_type calls for xbm_type and
1955 pbm_type to lookup_image_type.
1957 2012-09-22 Eli Zaretskii <eliz@gnu.org>
1959 * keyboard.c (timer_check_2): Move calculation of 'timers' and
1960 'idle_timers' from here ...
1961 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
1962 lists, to avoid infloops when the timer does something stupid,
1963 like reinvoke itself with the same or smaller time-out.
1966 2012-09-22 Martin Rudalics <rudalics@gmx.at>
1968 * window.c (Fsplit_window_internal): Handle only Qt value of
1969 Vwindow_combination_limit separately.
1970 (Qtemp_buffer_resize): New symbol.
1971 (Vwindow_combination_limit): New default value.
1974 2012-09-22 Eli Zaretskii <eliz@gnu.org>
1976 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
1977 the new overlay string. (Bug#10159)
1979 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
1981 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
1982 or that fprintf is async-signal-safe. POSIX doesn't require
1985 2012-09-22 Chong Yidong <cyd@gnu.org>
1987 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
1990 2012-09-22 Kenichi Handa <handa@gnu.org>
1992 * composite.c (composition_reseat_it): Handle the case that a
1993 grapheme cluster is not covered by a single font (Bug#12352).
1995 2012-09-21 Chong Yidong <cyd@gnu.org>
1997 * image.c (define_image_type): Avoid adding duplicate types to
1998 image_types (Bug#12463). Suggested by Jörg Walter.
2000 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2002 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
2003 (print_load_command_name): Add case LC_DATA_IN_CODE.
2004 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
2006 2012-09-21 Glenn Morris <rgm@gnu.org>
2008 * eval.c (Frun_hook_with_args_until_success)
2009 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
2011 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
2013 * fileio.c (Ffile_selinux_context): Only call freecon when
2014 lgetfilecon succeeded.
2015 (Fset_file_selinux_context): Likewise. (Bug#12444)
2017 2012-09-21 Eli Zaretskii <eliz@gnu.org>
2019 * xdisp.c (try_window_reusing_current_matrix): Under bidi
2020 reordering, locate the cursor by calling set_cursor_from_row; if
2021 that fails, clear the desired glyph matrix before returning a
2022 failure indication to the caller. Fixes leaving garbled display
2023 when fast scrolling with a down-key. (Bug#12403)
2024 (compute_stop_pos_backwards): Fix a typo that caused crashes while
2025 scrolling through multibyte text.
2027 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
2029 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
2030 calling mark_vectorlike since that's the one that marks the window.
2031 (mark_discard_killed_buffers): Mark the final cdr.
2032 * window.h (struct window): Move prev/next_buffers to the
2033 non-standard fields.
2034 * window.c (make_window): Initialize prev/next_buffers manually.
2036 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
2038 Omit unused arg EXPECTED from socket hooks.
2039 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
2040 * nsterm.m (ns_term_init):
2041 * termhooks.h (struct terminal.read_socket_hook):
2042 * w32inevt.c (w32_console_read_socket):
2043 * w32term.c (w32_read_socket):
2044 * xterm.c (XTread_socket):
2045 Omit unused arg EXPECTED. All callers changed.
2046 (store_user_signal_events): Return void, not int, since callers no
2047 longer care about the return value. All uses changed.
2049 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
2051 * w32gui.h (XParseGeometry): Do not declare.
2053 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
2055 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
2056 Ignore 'expected'. See Eli Zaretskii in
2057 <http://bugs.gnu.org/12471#8> (last line).
2059 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
2060 (XParseGeometry): Now static. Substitute extremal values for
2061 values that are out of range.
2063 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
2065 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
2067 * nsfns.m (XParseGeometry): Remove.
2068 (Fx_create_frame): Call x_set_offset to correctly interpret
2069 top_pos in geometry.
2071 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
2072 (Fx_parse_geometry): If there is a space in string, call
2073 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
2075 2012-09-17 Eli Zaretskii <eliz@gnu.org>
2077 * search.c (scan_buffer): Use character positions in calls to
2078 region_cache_forward and region_cache_backward, not byte
2079 positions. (Bug#12196)
2081 * w32term.c (w32_read_socket): Set pending_signals to 1, like
2082 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
2084 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
2085 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
2086 emacs_blocked_malloc, now deleted.
2088 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
2090 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
2091 The workaround was for improving performance on Solaris 2.4, but
2092 is getting in the way now. Emacs will still work if someone is
2093 still running Solaris 2.4 in a museum somewhere; Sun dropped
2094 support for Solaris 2.4 in 2003.
2095 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
2096 * process.c (create_process) [HAVE_WORKING_VFORK]:
2097 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
2098 since Emacs no longer uses vfork on that platform.
2100 2012-09-17 Glenn Morris <rgm@gnu.org>
2102 * emacs.c: Use COPYRIGHT.
2104 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
2106 Remove configure's --without-sync-input option (Bug#12450).
2107 When auditing signal-handling in preparation for cleaning it up,
2108 I found that SYNC_INPUT has race conditions and would be a real
2109 pain to fix. Since it's an undocumented and deprecated
2110 configure-time option, now seems like a good time to remove it.
2111 Also see <http://bugs.gnu.org/11080#16>.
2112 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
2113 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
2114 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
2115 (malloc_hysteresis):
2116 (check_depth) [XMALLOC_OVERRUN_CHECK]:
2117 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
2118 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
2119 (dont_register_blocks, bytes_used_when_reconsidered)
2120 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
2121 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
2122 [!SYSTEM_MALLOC && !SYNC_INPUT]:
2123 Remove. All uses removed.
2124 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
2125 implementation, one that depends on whether the new macro
2126 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
2128 * atimer.c (run_timers, handle_alarm_signal):
2129 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
2130 (handle_async_input, process_pending_signals)
2131 (handle_input_available_signal, init_keyboard):
2132 * nsterm.m (ns_read_socket):
2133 * process.c (wait_reading_process_output):
2134 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
2135 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
2137 * xterm.c (XTread_socket):
2139 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
2140 * eval.c (handling_signal): Remove. All uses removed.
2141 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
2142 All uses replaced with the SYNC_INPUT version.
2143 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
2145 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
2148 * font.c (Ffont_shape_gstring): Remove unused local.
2150 2012-09-16 Glenn Morris <rgm@gnu.org>
2152 * Makefile.in (clean): No longer run nextstep's clean.
2154 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
2156 (ns-app): Move here from ns.mk, and simplify.
2157 (clean): Simplify nextstep entry.
2158 * ns.mk: Remove file.
2160 2012-09-17 Kenichi Handa <handa@gnu.org>
2162 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
2163 not covert the last few charactes.
2165 2012-09-16 Kenichi Handa <handa@gnu.org>
2167 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
2168 here, but just check the validity of glyphs in the glyph-string.
2170 2012-09-16 Martin Rudalics <rudalics@gmx.at>
2172 * window.c (Fwindow_parameter, Fset_window_parameter):
2173 Accept any window as argument (Bug#12452).
2175 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
2177 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
2178 to ns_term_init to avoid memory leak.
2180 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
2181 explicit retain/release.
2182 (ns_term_init): Only allow one display. Initialize outerpool and
2185 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
2187 Port _setjmp fix to POSIXish hosts as well as Microsoft.
2188 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
2189 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
2190 the Microsoft problem in a different way, by altering ../nt/config.nt.
2192 2012-09-15 Eli Zaretskii <eliz@gnu.org>
2207 * w16select.c: Remove inclusion of setjmp.h, as it is now included
2208 by lisp.h. This completes removal of setjmp.h inclusion
2209 erroneously announced in the previous commit. (Bug#12446)
2211 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
2214 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
2215 not defined as a macro. The latter happens on MS-Windows.
2218 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
2220 Port better to POSIX hosts lacking _setjmp (Bug#12446).
2221 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
2222 Some instances of '#include <setjmp.h>' removed, if the
2223 only reason for the instance was because "lisp.h" was included.
2224 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
2225 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
2226 and _longjmp with the new symbols. Emacs already uses _setjmp if
2227 available, so this change affects only POSIXish hosts that have
2228 sigsetjmp but not _setjmp, such as some versions of Solaris and
2229 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
2230 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
2231 (png_load_body) [HAVE_PNG]:
2232 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
2233 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
2234 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
2235 since PNG requires jmp_buf. This is the only exception to the
2236 general rule that we now use sys_setjmp and sys_longjmp.
2237 This exception is OK since this code does not change the signal
2238 mask or longjmp out of a signal handler.
2240 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
2242 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
2243 Include "syssignal.h", for 'main_thread'.
2245 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
2247 Avoid out-of-range marker position (Bug#12426).
2248 * insdel.c (replace_range, replace_range_2):
2249 Adjust markers before overlays, as suggested by comments.
2250 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
2251 Remove redundant check before calling offset_intervals.
2253 2012-09-14 Martin Rudalics <rudalics@gmx.at>
2255 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
2256 current buffer (Bug#12387).
2258 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
2260 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
2262 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
2264 Use a more backwards-compatible timer format (Bug#12430).
2265 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
2266 vector element, not from the 4th, since PSECS is now at the end.
2267 (Fcurrent_idle_time): Doc fix.
2269 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
2271 Function to mark objects and remove killed buffers at once.
2272 * alloc.c (discard_killed_buffers): Rename to ...
2273 (mark_discard_killed buffers) ... new name. Add marking
2274 of remaining objects. Fix comment. Adjust users.
2275 (mark_object): Do not touch frame buffer lists here.
2276 * frame.c (delete_frame): Reset frame buffer lists here.
2278 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
2280 Better workaround for GNOME bug when --enable-gcc-warnings.
2281 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
2282 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
2283 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
2285 Simplify SIGIO usage (Bug#12408).
2286 The code that dealt with SIGIO was crufty and confusing, e.g., it
2287 played tricks like "#undef SIGIO" but these tricks were not used
2288 consistently. Simplify mostly by not #undeffing standard symbols,
2289 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
2290 or not as we please) rather than "defined SIGIO" (standard symbol
2291 that we probably shouldn't #undef).
2292 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
2293 Modules that need it can include it.
2294 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
2295 * dispextern.h (ignore_sigio): New decl.
2296 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
2297 unconditionally, since it's now a no-op if !USABLE_SIGIO.
2298 * emacs.c (shut_down_emacs):
2299 * keyboard.c (kbd_buffer_store_event_hold):
2300 Use ignore_sigio rather than invoking 'signal' directly.
2301 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
2303 (FIONREAD, SIGIO): Do not #undef.
2304 (tty_read_avail_input): Use #error rather than a syntax error.
2305 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
2306 for I_PIPE, used by SETUP_SLAVE_PTY.
2307 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
2308 * sysdep.c (croak): Remove; no longer needed. This bit of
2309 temporary code, with Fred N. Fish's comment that it's temporary,
2310 has been in Emacs since at least 1992!
2311 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
2312 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
2313 * syssignal.h (croak): Remove decl.
2314 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
2315 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
2316 now that we're termios-only.
2317 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
2318 * term.c (dissociate_if_controlling_tty): Use #error rather than
2321 Work around GCC and GNOME bugs when --enable-gcc-warnings.
2322 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
2323 to work around GNOME bug 683906.
2324 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
2325 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
2326 This works around GCC bug 54561.
2328 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
2330 More fixes for 'volatile' and setjmp/longjmp.
2331 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
2332 * image.c (struct png_load_context) [HAVE_PNG]: New type.
2333 (png_load_body) [HAVE_PNG]:
2334 (jpeg_load_body) [HAVE_JPEG]:
2335 New function, with most of the old parent function's body.
2336 (png_load) [HAVE_PNG]:
2337 (jpeg_load) [HAVE_JPEG]:
2338 Invoke the new function, to avoid longjmp munging our locals.
2339 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
2340 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
2341 longjmp is passed 2, as the C standard doesn't guarantee this.
2342 Instead, store the failure code into mgr->failure_code.
2344 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
2346 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
2347 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
2348 (syms_of_keyboard): Remove support for unread-command-char.
2350 2012-09-12 Eli Zaretskii <eliz@gnu.org>
2352 * w32proc.c (sys_kill): If PID is our process ID and the signal is
2353 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
2354 violation. (Bug#12426)
2356 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
2358 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
2360 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
2362 * eval.c: Add `inhibit-debugger'.
2363 (Qinhibit_debugger): New symbol.
2364 (call_debugger): Bind it instead of Qdebug_on_error.
2365 (maybe_call_debugger): Test Vinhibit_debugger.
2366 (syms_of_eval): Define inhibit-debugger.
2367 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
2368 (syms_of_xdisp): Remove inhibit-debug-on-message.
2370 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
2372 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
2373 If a nonvolatile local variable is written before a _longjmp to
2374 the frame containing the variable, and is read after the _longjmp,
2375 the value read is indeterminate. Some local variables of type
2376 'struct handler' and 'struct catchtag' are used in this way, so
2377 mark each of their slots as volatile if the slot can be set before
2378 _longjmp and read afterwards.
2379 * lisp.h (struct handler): var and chosen_clause are now volatile.
2380 (struct catchtag): val, next, and pdlcount are now volatile.
2382 * bidi.c (bidi_push_it, bidi_pop_it):
2383 * fns.c (copy_hash_table):
2384 * image.c (define_image_type):
2385 * keyboard.c (kbd_buffer_store_event_hold):
2386 * process.c (Fprocess_send_eof):
2387 * xfaces.c (x_create_gc) [HAVE_NS]:
2388 * xgselect.c (xg_select):
2389 Prefer assignment to memcpy when either will do.
2391 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
2392 Use pointer-to-a-pointer to simplify and avoid a NILP check each
2393 time an item is removed. No need to mark this function 'inline';
2394 the compiler knows better than we do.
2396 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
2398 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
2399 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
2400 to change_frame_size (Bug#12388).
2401 (windowDidResize:): Pass YES to updateFrameSize.
2403 * nsterm.h: Add delay parameter to updateFrameSize.
2405 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
2407 Discard killed buffers from deleted window and frame objects.
2408 This reduces an amount of references to killed buffers and
2409 helps GC to reclaim them faster.
2410 * alloc.c (discard_killed_buffers): New function.
2411 (mark_object): Use it for deleted windows and frames.
2412 (mark_object): If symbol's value is set up for a killed buffer
2413 or deleted frame, restore its global binding.
2414 * data.c (swap_in_global_binding): Add GC notice.
2415 (swap_in_symval_forwarding): Use convenient set_blv_where.
2416 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
2417 * window.h: ... to here.
2419 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
2421 Convenient macro to check whether the buffer is live.
2422 * buffer.h (BUFFER_LIVE_P): New macro.
2423 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
2424 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
2426 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2428 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
2429 composition cases (Bug#12364).
2431 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
2432 overhang of succeeding glyphs overlapping box cursor.
2434 * w32term.c (x_draw_glyph_string): Likewise.
2436 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
2438 Simplify, document, and port floating-point (Bug#12381).
2439 The porting part of this patch fixes bugs on non-IEEE platforms
2440 with frexp, ldexp, logb.
2441 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
2443 * floatfns.c: Simplify discussion of functions that Emacs doesn't
2444 support, by removing commented-out code and briefly listing the
2445 C89 functions excluded. The commented-out stuff was confusing
2446 maintenance, e.g., we thought we needed cbrt but it was commented out.
2447 (logb): Remove decl; no longer needed.
2448 (isfinite): New macro, if not already supplied.
2449 (isnan): Don't replace any existing macro.
2450 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
2451 are present on all C89 platforms.
2452 (Ffrexp): Do not special-case zero, as frexp does the right thing
2454 (Flogb): Do not use logb, as it doesn't have the desired meaning
2455 on hosts that use non-base-2 floating point. Instead, stick with
2456 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
2457 frexp, to avoid getting an unspecified result.
2459 * xdisp.c (Qinhibit_debug_on_message): Now static.
2461 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
2463 * nsterm.m (ns_update_begin): Set clip path to whole view by using
2464 NSBezierPath (Bug#12131).
2466 2012-09-10 Chong Yidong <cyd@gnu.org>
2468 * fns.c (Fdelq, Fdelete): Doc fix.
2470 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
2472 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
2473 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
2475 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
2477 * lisp.h (make_lisp_ptr): New macro to replace XSET.
2478 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
2481 2012-09-09 Eli Zaretskii <eliz@gnu.org>
2483 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
2484 left fringe if the window has a left margin. This avoids leaving
2485 traces of the cursor because its leftmost pixel is not drawn over.
2487 * dispnew.c (update_window_line): When the left margin area of a
2488 screen line is updated, set the redraw_fringe_bitmaps_p flag of
2489 that screen line. (Bug#12277)
2491 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
2493 Assume C89 or later for math functions (Bug#12381).
2494 This simplifies the code, and makes it a bit smaller and faster,
2495 and (most important) makes it easier to clean up signal handling
2496 since we can stop worring about floating-point exceptions in
2497 library code. That was a problem before C89, but the problem
2498 went away many years ago on all practical Emacs targets.
2499 * data.c, image.c, lread.c, print.c:
2500 Don't include <math.h>; no longer needed.
2501 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
2502 might be autoconfigured, as that never happens.
2504 * doprnt.c (DBL_MAX_10_EXP):
2505 * print.c (DBL_DIG):
2506 Remove. C89 or later always defines these.
2507 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
2508 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
2509 (arith_error, domain_error, domain_error2):
2510 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
2511 no longer needed -- we simply return what C returns. All uses removed.
2512 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
2514 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
2515 Remove. All uses expanded, as these macros are no longer used
2516 more than once and are now more trouble than they're worth.
2517 (Ftan): Use tan, not sin / cos.
2518 (Flogb): Assume C89 frexp.
2519 (fmod_float): Assume C89 fmod.
2520 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
2521 (init_floatfns): Remove. All uses removed.
2523 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
2525 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
2526 compositeToPoint for OSX < 10.6 (Bug#12390).
2528 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
2530 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
2531 This produces more-accurate results.
2533 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
2535 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
2536 changes (Bug#12088).
2538 2012-09-08 Chong Yidong <cyd@gnu.org>
2540 * syntax.c (Fstring_to_syntax): Doc fix.
2542 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
2544 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
2545 in the internal border.
2546 (x_set_window_size): Remove static variables and their usage.
2547 (ns_redraw_scroll_bars): Fix NSTRACE arg.
2548 (ns_after_update_window_line, ns_draw_fringe_bitmap):
2549 Remove fringe/internal border adjustment (Bug#11052).
2550 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
2551 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
2552 (ns_fix_rect_ibw): Remove.
2553 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
2554 (ns_dumpglyphs_box_or_relief): Ditto.
2555 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
2557 (ns_dumpglyphs_image): Ditto.
2558 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
2560 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
2561 their usage. Add fringe_extended_p and its use as in other terms.
2562 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
2563 scroll bar was removed.
2564 (updateFrameSize): New function.
2565 (windowDidResize): Move code to updateFrameSize and call it.
2567 * nsterm.h (EmacsView): Add updateFrameSize.
2569 2012-09-07 Chong Yidong <cyd@gnu.org>
2571 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
2573 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
2575 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
2577 More signal-handler cleanup (Bug#12327).
2578 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
2579 Problem introduced when merging patches. Noted by Eli Zaretskii in
2580 <http://bugs.gnu.org/12327#67>.
2581 * floatfns.c: Comment fix.
2582 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
2583 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
2584 and anyway the declaration is harmless even if SIGDANGER is not defined.
2585 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
2586 defined BROKEN_FIONREAD). systty.h formerly did this, but other
2587 source files not surprisingly expected syssignal.h to define, or
2588 not define, SIGIO, and it's cleaner to do it that way, for consistency.
2589 Include <sys/ioctl.h>, for FIONREAD.
2590 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
2591 This eliminates a problem whereby other files mysteriously had
2592 to include "syssignal.h" before including "systty.h" if they
2593 wanted to use "#ifdef SIGIO".
2595 2012-09-07 Eli Zaretskii <eliz@gnu.org>
2597 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
2599 * w32.c (sigemptyset): Empty the set.
2600 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
2602 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
2604 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
2606 * alloc.c (mark_buffer): Revert unsafe marking optimization.
2607 (mark_object): Likewise for frame objects.
2609 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
2611 * syssignal.h (handle_on_main_thread): Always declare,
2612 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
2613 This ports to platforms without HAVE_PTHREAD.
2615 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
2617 Signal-handler cleanup (Bug#12327).
2618 Emacs's signal handlers were written in the old 4.2BSD style with
2619 sigblock and sigmask and so forth, and this led to some
2620 inefficiencies and confusion. Rewrite these to use
2621 pthread_sigmask etc. without copying signal sets around. Also,
2622 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
2623 'signal', and instead use functions that do not attempt to take
2624 over the system name space. This patch causes Emacs's text
2625 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
2626 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
2627 Do not include <signal.h> or "syssignal.h", as these
2628 modules do not use signals.
2629 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
2630 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
2631 Do not include <signal.h>, as "syssignal.h" does that for us now.
2632 * atimer.c (sigmask_atimers): New function.
2633 (block_atimers, unblock_atimers): New functions,
2634 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
2636 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
2637 no longer needed here.
2638 * emacs.c (main): Inspect existing signal handler with sigaction,
2639 so that there's no need to block and unblock SIGHUP.
2640 * sysdep.c (struct save_signal): New member 'action', replacing
2641 old member 'handler'.
2642 (save_signal_handlers, restore_signal_handlers):
2643 Use sigaction instead of 'signal' to save and restore.
2644 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
2645 New function. All users of 'signal' modified to use set_sighandler
2646 if they're writeonly, and to use sys_signal if they're read+write.
2647 (emacs_sigaction_init, forwarded_signal): New functions.
2648 (sys_signal): Remove. All uses replaced by calls to sigaction
2649 and emacs_sigaction_init, or by direct calls to 'signal'.
2650 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
2651 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
2652 all uses replaced by pthread_sigmask etc. calls.
2653 * syssignal.h: Include <signal.h>.
2654 (emacs_sigaction_init, forwarded_signal): New decls.
2655 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
2656 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
2657 (sigmask, sys_sigmask): Remove; no longer needed.
2658 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
2659 (sigblock, sigunblock, sigfree):
2660 (sigsetmask) [!defined sigsetmask]:
2661 Remove. All uses replaced by pthread_sigmask.
2662 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
2663 no longer need to be replaced, and its typical old uses
2664 are now done via emacs_sigaction_init and sigaction.
2665 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
2666 (sys_sigdel): Remove; unused.
2667 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
2669 2012-09-06 Eli Zaretskii <eliz@gnu.org>
2671 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
2672 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
2674 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
2676 Explicitly mark buffer_defaults and buffer_local_symbols.
2677 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
2678 mark_local_symbols here.
2679 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
2680 since special buffers aren't marked here any more.
2681 (allocate_buffer): Chain new buffer with all_buffers here...
2682 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
2684 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
2685 (syms_of_buffer): Remove staticpro of the above.
2686 (init_buffer_once): Set names for buffer_defaults and
2687 buffer_local_symbols.
2689 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
2691 Use bool for booleans in font-related modules.
2692 * font.c (font_intern_prop, font_style_to_value)
2693 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
2694 (generate_otf_features, font_check_otf_features, font_check_otf)
2695 (font_match_p, font_list_entities, font_at):
2696 * fontset.c (fontset_id_valid_p, reorder_font_vector
2697 (fontset_find_font, Fset_fontset_font)
2698 (face_suitable_for_char_p) [0]:
2699 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
2700 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
2701 (m17n_flt_initialized, ftfont_shape_by_flt):
2702 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
2703 * nsfont.m (nsfont_draw):
2704 * w32font.c (w32font_draw):
2705 * w32term.c (x_draw_glyphless_glyph_string_foreground):
2706 Use bool for booleans.
2707 * font.h: Adjust to above API changes.
2708 (struct font, struct font_driver, struct font_driver_list):
2709 Use bool for booleans.
2710 (struct font): Remove useless member encoding_type.
2712 * fontset.c, xftfont.c: Omit unnecessary static decls.
2714 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
2716 * alloc.c (mark_object): Revert window marking code
2717 since it's unsafe for the Fset_window_configuration.
2719 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
2721 Fix race conditions with signal handlers and errno (Bug#12327).
2722 Be more systematic about preserving errno whenever a signal
2723 handler returns, even if it's not in the main thread. Do this by
2724 renaming signal handlers to distinguish between signal delivery
2725 and signal handling. All uses changed.
2726 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
2727 * data.c (deliver_arith_signal): Rename from arith_error.
2728 * dispnew.c (deliver_window_change_signal): Rename from
2729 window_change_signal.
2730 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
2731 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
2732 * keyboard.c (deliver_input_available_signal): Rename from
2733 input_available_signal.
2734 (deliver_user_signal): Rename from handle_user_signal.
2735 (deliver_interrupt_signal): Rename from interrupt_signal.
2736 * process.c (deliver_pipe_signal): Rename from send_process_trap.
2737 (deliver_child_signal): Rename from sigchld_handler.
2738 * atimer.c (handle_alarm_signal):
2739 * data.c (handle_arith_signal):
2740 * dispnew.c (handle_window_change_signal):
2741 * emacs.c (handle_fatal_signal, handle_danger_signal):
2742 * keyboard.c (handle_input_available_signal):
2743 * keyboard.c (handle_user_signal, handle_interrupt_signal):
2744 * process.c (handle_pipe_signal, handle_child_signal):
2745 New functions, with the actual signal-handling code taken from the
2746 original respective signal handlers, sans the sporadic attempts to
2747 preserve errno, since that's now done by handle_on_main_thread.
2748 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
2749 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
2750 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
2752 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
2753 Move initialization of main_thread to sysdep.c's init_signals.
2754 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
2755 our usage, and simplifies the mainline code.
2756 (record_child_status_change): New static function, as a helper
2757 for handle_child_signal, and with most of the old child handler's
2759 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
2760 (handle_child_signal): Use the above.
2761 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
2762 Moved here from emacs.c.
2763 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
2764 code moved here from emacs.c's main function.
2765 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
2766 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
2767 This lets callers save and restore errno properly.
2769 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
2771 Remove redundant or unused things here and there.
2772 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
2773 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
2774 * editfns.c (Fcompare_buffer_substrings): Likewise.
2775 * frame.h (struct terminal, struct font_driver_list):
2776 Remove redundant declarations.
2777 * window.h (Qleft, Qright): Likewise.
2779 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
2781 Do not mark objects from deleted buffers, windows and frames.
2782 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
2783 (mark_object): Likewise for windows and frames.
2785 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
2787 * alloc.c (valid_lisp_object_p): Treat killed buffers,
2788 buffer_defaults and buffer_local_symbols as valid objects.
2789 Return special value to denote them.
2791 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
2793 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
2794 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
2795 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
2796 (file_name_absolute_p, Fsubstitute_in_file_name):
2797 (check_executable, check_writable, Ffile_accessible_directory_p)
2798 (Fset_file_selinux_context, Fdefault_file_modes)
2799 (Finsert_file_contents, choose_write_coding_system)
2800 (Fwrite_region, build_annotations, a_write, e_write)
2802 * filelock.c (boot_time_initialized, get_boot_time)
2803 (get_boot_time_1, lock_file_1, within_one_second):
2804 * floatfns.c (in_float):
2805 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
2806 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
2807 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
2808 * lisp.h (struct Lisp_Hash_Table.cmpfn):
2809 * window.c (compare_window_configurations):
2810 Use bool for booleans.
2811 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
2812 (Fdefault_file_modes): Now mode_t, not int, for modes.
2813 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
2814 (internal_delete_file): Now returns void, not a (boolean) int,
2815 since nobody was looking at the return value.
2816 * lisp.h, window.h: Adjust to above API changes.
2818 * xdisp.c (set_message): Simplify and reindent last change.
2820 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
2822 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
2824 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
2826 * eval.c (call_debugger): Make the function non-static so that we
2827 can call it from set_message.
2829 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
2830 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
2832 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
2834 Give more-useful info on a fatal error (Bug#12328).
2835 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
2836 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
2837 of doing the work ourselves.
2838 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
2839 do most of the work.
2840 (fatal_error_backtrace): New function, taken from the guts
2841 of the old fatal_error_signal, but with a new option to output
2843 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
2844 info about the signal than just its number.
2845 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
2846 * sysdep.c: Include <execinfo.h>
2847 (emacs_backtrace): New function, taken partly from the previous
2848 code of the 'die' function.
2849 (emacs_abort): Call fatal_error_backtrace rather than abort.
2851 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
2853 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
2854 eager (load-time) macro-expansion.
2855 * lisp.mk (lisp): Add macroexp.
2857 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
2859 Simplify redefinition of 'abort' (Bug#12316).
2860 Do not try to redefine the 'abort' function. Instead, redo
2861 the code so that it calls 'emacs_abort' rather than 'abort'.
2862 This removes the need for the NO_ABORT configure-time macro
2863 and makes it easier to change the abort code to do a backtrace.
2864 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
2865 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
2866 Remove; sysdep.c's emacs_abort now takes its place.
2867 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
2868 'abort' changed to use 'emacs_abort'.
2869 * msdos.c (dos_abort) [defined abort]: Remove; not used.
2870 (abort) [!defined abort]: Rename to ...
2871 (emacs_abort): ... new name.
2872 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
2873 the place of the old 'abort' in emacs.c.
2874 * w32.c, w32fns.c (abort): Do not #undef.
2875 * w32.c (emacs_abort): Rename from w32_abort.
2877 2012-09-04 Eli Zaretskii <eliz@gnu.org>
2879 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
2880 offsets[j].dv, since the y axis of the screen coordinates points
2881 down, while the y axis of the font definition coordinates points
2882 up. This fixes display of Arabic diacritics such as KASRA and
2883 KASRATAN. (Bug#11860)
2885 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
2887 Be more systematic about _setjmp vs setjmp.
2888 * alloc.c (test_setjmp, mark_stack):
2889 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
2890 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
2891 (png_load, my_error_exit, jpeg_load):
2892 * process.c (send_process_trap, send_process):
2893 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
2894 The underscored versions are up to 30x faster on some hosts.
2895 Formerly, the code used setjmp+longjmp sometimes and
2896 _setjmp+_longjmp at other times, with no particular reason to
2897 prefer setjmp+longjmp.
2899 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
2901 Fix minor problem found by static checking.
2902 * buffer.c (Fdelete_all_overlays): Return nil.
2904 2012-09-03 Martin Rudalics <rudalics@gmx.at>
2906 * buffer.c (Fdelete_all_overlays): New function.
2908 2012-09-03 Chong Yidong <cyd@gnu.org>
2910 * gtkutil.c: Add extern decl for Qxft.
2912 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>

2926 All callers changed.
2927 * eval.c (interactive_p): Omit always-true boolean argument
2928 EXCLUDE_SUBRS_P. All callers changed.
2929 * dispextern.h, lisp.h: Reflect above API changes.
2930 * firstfile.c (dummy): Use the address of 'main', whose signature
2931 won't change, instead of the address of 'initialize', whose
2932 signature just changed from int to bool.
2933 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
2934 * msdos.c (fatal_error_in_progress): ... from here.
2935 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
2937 (redisplay_internal, unwind_redisplay): Simply clear
2938 REDISPLAYING_P when unwinding, instead of saving its previous,
2939 always-false value and then restoring it.
2941 Clean up some extern decls.
2942 Mostly, this hoists extern decls out of .c files and into .h files.
2943 That way, we're more likely to catch errors if the interfaces change.
2944 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
2945 declare xg_mark_data.
2946 * dispextern.h (x_frame_parm_handlers):
2948 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)

2964 * xfont.c (x_clear_errors):
2965 * xterm.c (x_frame_parm_handlers):
2966 Remove now-redundant extern decls.
2967 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
2968 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
2970 * xfaces.c: Remove unnecessary static decls.
2971 * xterm.c (updating_frame): Remove decl of nonexistent object.
2973 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
2974 when building globals.h, as the objects that are not built on
2975 this host are not needed to compile C files on this host.
2977 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
2979 * gtkutil.h: Remove prototype for x_wm_set_size_hint.

2993 (make_buffer_string, make_buffer_string_both)
2994 (Fsubst_char_in_region, Ftranslate_region_internal, Fformat):

3006 (set_intervals_multibyte_1, set_intervals_multibyte):
3007 * keyboard.c (decode_timer):
3008 Use bool for boolean.
3009 * intervals.h, lisp.h, systime.h: Reflect above API changes.
3010 * editfns.c (struct info): Use 1-bit unsigned bitfields for booleans.
3012 2012-09-02 Chong Yidong <cyd@gnu.org>
3014 * keymap.c (push_key_description): Print M-TAB as C-M-i
3017 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
3019 * makefile.w32-in (CCL_H, W32FONT_H): New macros.
3020 (ATIMER_H, FONT_H, $(BLD)/alloc.$(O), $(BLD)/callproc.$(O))

3025 ($(BLD)/w32font.$(O), $(BLD)/w32uniscribe.$(O)): Update dependencies.
3027 2012-09-01 Eli Zaretskii <eliz@gnu.org>
3029 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
3030 more than one grapheme cluster passed to the shaper: compute the
3031 offset adjustment values separately for each cluster. (Bug#11860)
3033 * image.c: Restore mistakenly removed inclusion of w32.h. Without
3034 it, GCC doesn't see prototypes of w32_delayed_load, and complains
3035 about implicit conversions from integer to pointer.
3037 2012-09-01 Daniel Colascione <dancol@dancol.org>
3039 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
3040 system used too early.
3042 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
3044 Better seed support for (random).

3073 * process.c: Include TERM_HEADER instead of listing all possible
3074 window-system headers.
3076 * nsterm.h: Remove declarations now in frame.h.
3077 Define FRAME_X_SCREEN, FRAME_X_VISUAL.
3079 * menu.c: Include TERM_HEADER instead of listing all possible
3080 window-system headers.
3082 * keyboard.h: Declare ignore_mouse_drag_p whenever we have a
3085 * keyboard.c: Include TERM_HEADER instead of listing all possible
3086 window-system headers.
3088 * image.c: Include TERM_HEADER instead of listing all possible
3089 window-system headers. Declare Vlibrary_cache when compiling for
3092 * gtkutil.h (xg_list_node_): Include xterm.h to pick up needed
3093 window system declarations.
3095 * frame.h: Move common functions here: set_frame_menubar,
3096 x_set_window_size, x_sync, x_get_focus_frame,
3097 x_set_mouse_position, x_set_mouse_pixel_position,
3098 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

3119 the current window system; include in list of objects to link into
3122 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
3124 Remove mark_ttys function and fix tty_display_info initialization.
3125 * lisp.h (mark_ttys): Remove prototype.
3126 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
3127 to mark_ttys because all possible values of 'top_frame' slot are
3128 the frames which are reachable from Vframe_list.
3129 * term.c (mark_ttys): Remove.
3130 (init_tty): Safely initialize 'top_frame' slot with Qnil.
3132 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
3134 Change struct frame bitfields from unsigned char to unsigned.

3137 'auto_raise', 'auto_lower', 'no_split', 'explicit_name',
3138 'window_sizes_changed', 'mouse_moved' and 'pointer_invisible'
3139 bitfields from unsigned char to unsigned.

3152 2012-08-30 Paul Eggert <eggert@cs.ucla.edu>
3154 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
3155 for GCC 4.7.1 x86-64.
3157 2012-08-30 Glenn Morris <rgm@gnu.org>
3159 * lread.c (init_lread): For out-of-tree builds, only add the
3160 source directory's site-lisp dir to the load-path if it exists,
3161 consistent with in-tree builds. (Bug#12302)
3163 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>
3165 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize

3167 (windowShouldClose:): Set window_closed.
3168 (dealloc): New member, free button_values.
3169 (process_dialog:): Make member function. Remove window argument,
3170 replace window with self. Count buttons and allocate and store values

3173 with tag. Remove return self, declare return value as void.
3174 (addString:row:): Remove return self, declare return value as void.
3175 (addSplit): Remove return self, declare return value as void.
3176 (clicked:): Remove return self, declare return value as void.
3177 Set dialog_return to button_values[seltag]. Code formatting change.
3178 (initFromContents:isQuestion:): Adjust call to process_dialog.
3179 Code formatting change.
3180 (timeout_handler:): Set timer_fired to YES.
3181 (runDialogAt:): Set timer_fired to NO.
3182 Handle click on close button as quit.
3184 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
3185 Add window_closed and button_values. Add void as return value for
3186 add(Button|String|Split). addButton takes int instead of Lisp_Object.
3187 Add process_dialog as new member.
3189 2012-08-28 Eli Zaretskii <eliz@gnu.org>
3191 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it
3192 is not one of the heaps we manage. (Bug#12242)
3194 2012-08-28 Glenn Morris <rgm@gnu.org>
3196 * eval.c (Fcalled_interactively_p): Doc fix. (Bug#11747)

3252 (change_frame_size_1, sit_for):
3253 Use bool for boolean.
3254 (clear_glyph_matrix_rows): Rename from enable_glyph_matrix_rows,
3255 and remove last int (actually boolean) argument, which was always 0.
3256 All callers changed.
3257 * dispextern.h, frame.h, lisp.h: Reflect above API changes.
3258 * dispextern.h (struct composition_it): Use bool for boolean.
3259 (struct glyph_matrix): Don't assume buffer sizes can fit in 'int'.
3260 (struct bidi_it): Use unsigned:1, not int, for boolean prev_was_pdf.
3261 * dired.c (file_name_completion):
3262 Use bool for boolean. (This was missed in an earlier change.)
3264 2012-08-27 Martin Rudalics <rudalics@gmx.at>
3266 * window.c (Fset_window_configuration): Revert first part of
3269 2012-08-27 Jan Djärv <jan.h.d@swipnet.se>
3271 * nsterm.h (NSPanel): New class variable dialog_return.
3273 * nsmenu.m (initWithContentRect:styleMask:backing:defer:):
3274 Initialize dialog_return.
3275 (windowShouldClose:): Use stop instead of stopModalWithCode.
3276 (clicked:): Ditto, and also set dialog_return (Bug#12258).
3277 (timeout_handler:): Use stop instead of abortModal. Send a dummy
3279 (runDialogAt:): Make ret Lisp_Object. Set it from dialog_return when

3324 Use bool for booleans.
3325 * coding.h, lisp.h: Reflect above API changes.
3326 * coding.c: Remove unnecessary static function decls.
3327 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
3328 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
3329 not a boolean 'int', since callers never look at the return value.
3330 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
3331 * coding.h (decoding_buffer_size, encoding_buffer_size)
3332 (emacs_mule_string_char): Remove unused extern decls.
3333 (struct iso_2022_spec, struct coding_system):

3335 (struct emacs_mule_spec): Remove unused field 'full_support'.
3336 All initializations removed.
3337 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
3339 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
3341 Fix spare memory change (Bug#12286).
3342 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
3343 (valid_lisp_object_p): Likewise.
3345 2012-08-27 Martin Rudalics <rudalics@gmx.at>
3347 * window.c (Fset_window_configuration): Record any window's old
3348 buffer if it's replaced (see Bug#8789). If the new current
3349 buffer doesn't appear in the selected window, go to its old
3352 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
3354 Special MEM_TYPE_SPARE to denote reserved memory.
3355 * alloc.c (enum mem_type): New memory type.
3356 (refill_memory_reserve): Use new type for spare memory.
3357 This prevents live_cons_p and live_string_p from incorrect
3358 detection of uninitialized objects from spare memory as live.
3360 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
3363 * Makefile.in (.PHONY): versioclean -> versionclean.
3365 Remove unused external symbols.
3366 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
3367 * window.c (Qwindow_valid_p, decode_valid_window):
3368 Now static, not extern.
3369 * data.c (Qinterval): Remove; unused.
3370 (syms_of_data): Do not define 'interval'.
3371 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
3372 * window.h (decode_valid_window):
3375 * character.c, charset.c, chartab.c: Use bool for booleans.

3385 (char_table_set_range, optimize_sub_char_table)
3386 (map_sub_char_table):
3387 Use bool for boolean.
3388 * character.c (str_to_unibyte): Omit last boolean argument; it was
3389 always 0. All callers changed.
3390 * character.h, charset.h: Adjust to match previous changes.
3391 * character.h (char_printable_p): Remove decl of nonexistent function.
3392 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
3393 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
3394 are all boolean, so make them single-bit bitfields.
3396 * lisp.h (ASET): Remove attempt to detect side effects.
3397 It was meant to be temporary and it often doesn't work,
3398 because when IDX has side effects the behavior of IDX==IDX
3399 is undefined. See Stefan Monnier in
3400 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
3402 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
3404 * lisp.h (functionp): New function (extracted from Ffunctionp).
3405 (FUNCTIONP): Use it.
3406 * eval.c (Ffunctionp): Use it.
3408 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
3410 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
3411 as that's faster and simpler than static storage. Don't bother
3412 with the g_main_context_query overhead if g_main_context_pending
3413 says no events are pending.
3414 (gfds, gfds_size): Remove these static vars.
3415 (xgselect_initialize): Remove; no longer needed.
3416 All uses and decls removed.
3418 * emacs.c (fatal_error_signal_hook): Remove.
3419 All uses removed. This leftover from old code was always 0.
3421 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
3422 * casefiddle.c (casify_object, casify_region):
3423 * casetab.c (set_case_table):
3424 * category.c, category.h (word_boundary_p):
3425 * category.h (CHAR_HAS_CATEGORY):
3426 Use bool for booleans, instead of int.
3428 2012-08-25 Eli Zaretskii <eliz@gnu.org>
3430 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
3432 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
3434 On assertion failure, print backtrace if available.
3435 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
3436 (die) [ENABLE_CHECKING]: Print a backtrace if available.
3437 * Makefile.in (LIB_EXECINFO): New macro.
3440 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
3441 * bytecode.c (exec_byte_code):
3442 * callint.c (check_mark, Fcall_interactively):
3443 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
3444 (getenv_internal, sync_process_alive, call_process_exited):
3445 * lisp.h (USE_SAFE_ALLOCA):
3446 Use bool for booleans, instead of int.
3447 * lisp.h, process.h: Adjust prototypes to match above changes.
3448 * callint.c (Fcall_interactively): Don't assume the mark's
3449 offset fits in 'int'.
3451 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
3453 * buffer.c, buffer.h: Use bool for boolean.
3454 * buffer.c (reset_buffer_local_variables)
3455 (buffer_lisp_local_variables, Fset_buffer_modified_p)
3456 (Frestore_buffer_modified_p, Fset_buffer_multibyte):

3459 (report_overlay_modification, call_overlay_mod_hooks):
3460 (mmap_enlarge, mmap_set_vars):
3461 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
3462 Use bool for booleans, instead of int.
3463 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
3464 since the 1-or-0 return value is always ignored anyway.
3465 (mmap_initialized_p):
3466 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
3467 * buffer.h, lisp.h: Adjust prototypes to match above changes.
3469 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
3471 * bidi.c: Use bool for boolean.
3472 This is a bit more readable, and makes the text segment of bidi.o
3473 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
3474 Presumably it's faster too.
3475 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
3477 (bidi_cache_find_level_change, bidi_cache_iterator_state)
3478 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
3479 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
3480 (bidi_explicit_dir_char, bidi_level_of_next_char)
3481 (bidi_find_other_level_edge, bidi_move_to_visually_next):
3482 Use bool for booleans, instead of int.
3483 * dispextern.h (bidi_init_it, bidi_paragraph_init)
3484 (bidi_unshelve_cache): Adjust decls to match code.
3486 2012-08-23 Martin Rudalics <rudalics@gmx.at>
3488 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
3491 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
3493 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
3494 * atimer.h: Include <stdbool.h>.
3496 2012-08-22 Dan Nicolaescu <dann@gnu.org>
3498 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
3499 compile time tests instead of run time tests on systems that do
3501 (FRAME_MAC_P): Remove leftover from deleted code.
3502 * frame.c (syms_of_frame): Remove leftover from deleted code.
3504 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
3506 * nsterm.m (insertText:): Don't clear modifiers if code is space.
3508 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
3510 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
3511 Otherwise, the compiler complains about (A?B:C) where B is void
3512 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
3513 (fontset_add): Return void, for FONTSET_ADD.
3515 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
3517 * alloc.c: Use bool for booleans.
3518 (gc_in_progress, abort_on_gc)
3519 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
3520 (dont_register_blocks) [GC_MALLOC_CHECK]:
3521 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
3522 (check_string_bytes, make_specified_string, memory_full)
3523 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
3524 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
3525 (mark_stack, valid_pointer_p, make_pure_string)
3526 (Fgarbage_collect, survives_gc_p, gc_sweep):
3527 Use bool for booleans, instead of int.
3528 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
3529 Remove unused local.
3530 * alloc.c (PURE_POINTER_P):
3531 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
3532 * editfns.c (Fformat):
3533 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
3535 * fns.c (sweep_weak_table):
3536 * lisp.h (suppress_checking, push_message, survives_gc_p)
3537 (make_pure_string, gc_in_progress, abort_on_gc):
3538 * lread.c (readchar, read1):
3539 * print.c (Fprin1_to_string):
3540 * xdisp.c (push_message):
3541 Use bool for booleans affected directly or indirectly by
3544 Make recently-introduced setters macros.
3545 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
3546 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
3547 (set_fontset_default, set_fontset_fallback): Rename from their
3548 upper-case counterparts, and make them functions rather than macros.
3549 This is more consistent with the other recently-introduced setters.
3550 These don't need to be inline, since they're local.
3552 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
3554 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
3555 the loop (Bug#12247).
3557 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
3559 * lisp.h (vcopy): Use memcpy rather than our own loop.
3560 This fixes a performance regression introduced by the recent
3561 addition of vcopy. This means 'vcopy' will need to be modified
3562 for a copying collector, but that's OK. Also, tighten the
3563 checking in the assertion.
3565 2012-08-21 Eli Zaretskii <eliz@gnu.org>
3567 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
3568 components for RTL text (Bug#11860). Adjust X-OFFSET of each
3569 non-base glyph for the width of the base character, according to
3570 what x_draw_composite_glyph_string_foreground expects.
3571 Generate WADJUST value according to composition_gstring_width's
3572 expectations, to produce correct width of the composed character.
3573 Reverse the sign of the DU offset produced by ScriptPlace.
3575 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
3577 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
3579 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
3581 Avoid direct writes to contents member of struct Lisp_Vector.
3582 * lisp.h (vcopy): New function to copy data into vector.
3583 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
3584 * fns.c (Ffillarray): Use ASET.
3585 * keyboard.c (timer_check_2): Use AREF and ASET.
3586 (append_tool_bar_item, Frecent_keys): Use vcopy.
3587 * lread.c (read_vector): Use ASET.
3588 * msdos.c (Frecent_doskeys): Use vcopy.
3589 * xface.c (Finternal_copy_lisp_face): Use vcopy.
3590 (Finternal_merge_in_global_face): Use ASET and vcopy.
3591 * xfont.c (xfont_list_pattern): Likewise.
3593 2012-08-21 Martin Rudalics <rudalics@gmx.at>
3595 * window.c (Fwindow_point): For the selected window always return
3596 the position of its buffer's point.
3597 (Fset_window_point): For the selected window always go in its
3598 buffer to the specified position.
3600 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
3602 Setter macros for fontsets.
3603 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
3604 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
3605 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
3608 2012-08-20 Glenn Morris <rgm@gnu.org>
3610 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
3611 Don't assume that `ln -f' works.
3613 2012-08-20 Eli Zaretskii <eliz@gnu.org>
3615 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
3616 and later about non-assignments with no effect. See discussion at
3617 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
3620 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
3622 Inline setter functions for Lisp_Objects slots of struct specbinding.
3623 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
3626 2012-08-20 Martin Rudalics <rudalics@gmx.at>
3628 * window.c (select_window): Always make selected window's buffer
3631 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
3633 Use AREF and ASET for docstrings of category tables.
3634 * category.h (CATEGORY_DOCSTRING): Use AREF.
3635 (SET_CATEGORY_DOCSTRING): Use ASET.
3636 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
3638 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
3640 Inline setter functions for hash table members.
3641 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
3642 (set_hash_hash, set_hash_index): Rename with _slot suffix.
3643 (set_hash_key_and_value, set_hash_index, set_hash_next)
3644 (set_hash_hash): New functions.
3645 * charset.c, fns.c: Adjust users.
3647 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
3649 Inline getter and setter functions for per-buffer values.
3650 * buffer.h (per_buffer_default, set_per_buffer_default)
3651 (per_buffer_value, set_per_buffer_value): New functions.
3652 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
3653 * buffer.c, data.c: Adjust users.
3655 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
3657 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
3659 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
3661 Rely on <config.h> + <unistd.h> to declare 'environ',
3662 as gnulib does this if the system doesn't.
3663 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
3664 Remove declaration. MS-Windows declares it on stdlib.h which is
3665 included by conf_post.h.
3666 * emacs.c (environ) [DOUG_LEA_MALLOC]:
3667 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.

3674 and avoid a gcc -Wmaybe-uninitialized diagnostic.
3676 2012-08-19 Chong Yidong <cyd@gnu.org>

3698 * chartab.c, lisp.h (char_table_set, char_table_set_range):
3699 Return void, not Lisp_Object. Otherwise, the compiler
3700 complains about (A?B:C) where B is void and C is Lisp_Object
3701 when compiling CHAR_TABLE_SET, due to the recent change to
3702 the API of sub_char_table_set_contents.

4532 2012-08-04 Eli Zaretskii <eliz@gnu.org>
4534 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
4535 * w32.c (init_environment): Change the default values of many
4536 environment variables in dflt_envvars[] to NULL, to avoid pushing
4537 them into environment when they were not already defined.
4538 Remove the code that deletes site-lisp subdirectories from the default
4539 value of EMACSLOADPATH, as it is no longer needed.
4540 (check_windows_init_file): Now external, not static.
4541 Use Vload_path as is, without adding anything, as this function is now
4542 called when Vload_path is already set up.
4544 * w32.h (check_windows_init_file): Add prototype.
4546 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build
4547 directory, ignore the /*/i386/ tail in Vinvocation_directory, for
4548 compatibility with Posix platforms.
4549 (main): Move the call to check_windows_init_file to here from
4551 (decode_env_path) [WINDOWSNT]: Expand the %emacs_dir%/ prefix, if
4552 any, in the DEFALT argument into the root of the Emacs build or
4553 installation tree, as appropriate.
4555 * callproc.c (init_callproc_1): Call decode_env_path instead of
4556 doing its equivalent by hand.
4557 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
4558 the code that sets Vexec_path run on MS-Windows.
4560 * lread.c (init_lread): Add comments to #ifdef's.
4562 * msdos.c (dos_set_window_size, IT_update_begin)
4563 (IT_frame_up_to_date, IT_set_frame_parameters): Use FVAR and WVAR
4564 instead of direct references.
4566 2012-08-04 Paul Eggert <eggert@cs.ucla.edu>
4568 Export DEFAULT_REHASH_* to GDB.
4569 * lisp.h (DEFAULT_REHASH_THRESHOLD, DEFAULT_REHASH_SIZE):
4570 Now constants, not macros.
4572 2012-08-03 Paul Eggert <eggert@cs.ucla.edu>
4574 Remove unnecessary casts involving pointers.
4575 These casts are no longer needed now that we assume C89 or later,
4576 since they involve casting to or from void *.
4577 * alloc.c (make_pure_string, make_pure_c_string, pure_cons)
4578 (make_pure_float, make_pure_vector):
4579 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP):

4584 * xdisp.c (x_produce_glyphs):
4585 * xfaces.c (compare_fonts_by_sort_order):
4586 * xfns.c (x_real_positions, select_visual):
4587 * xselect.c (x_stop_queuing_selection_requests)
4588 (x_get_window_property, x_get_window_property_as_lisp_data):
4589 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
4590 Remove unnecessary pointer casts.
4591 * alloc.c (record_xmalloc): New function.
4592 * lisp.h (record_xmalloc): New decl.
4593 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
4594 more like a function. This is because the pointer cast is not
4595 needed. All uses changed.
4596 * print.c (print_string, print_error_message): Avoid length recalc.
4598 Improve fix for macroexp crash with debugging (Bug#12118).
4599 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
4600 ARRAY_MARK_FLAG when checking subscripts, because ASET is
4601 not supposed to be invoked from the garbage collector.
4602 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
4603 (gc_aset): New function, which is like ASET but can be
4604 used in the garbage collector.
4605 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)
4606 (set_hash_index): Use it instead of ASET.
4608 2012-08-03 Eli Zaretskii <eliz@gnu.org>

4613 (revert_to_self): Forward declarations of static functions.
4614 <static BOOL g_b_init_get_security_info>:
4615 <g_b_init_create_symbolic_link>: New static flags.
4616 (globals_of_w32): Initialize them to zero.
4617 (GetSecurityInfo_Proc, CreateSymbolicLink_Proc): New typedefs.
4618 (map_w32_filename): Improve commentary. Simplify switch.
4619 (SYMBOLIC_LINK_FLAG_DIRECTORY): Define if not defined in system
4620 headers (most versions of MinGW w32api don't).
4621 (get_security_info, create_symbolic_link)
4622 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
4624 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
4625 in the argument file name.
4626 (sys_access): Call unc_volume_file_attributes only if
4627 GetFileAttributes fails with network-related error codes.
4628 (sys_rename): Diagnose renaming of a symlink when the user doesn't
4629 have the required privileges.
4630 (get_file_security_desc_by_name): Rename from
4631 get_file_security_desc.
4632 (stat_worker): New function, with most of the guts of 'stat', and
4633 with addition of handling of symlinks and support for 'lstat'.
4634 If possible, get file's attributes and security information by
4635 handle, not by name. Produce S_IFLNK bit for symlinks, when
4636 called from 'lstat'.
4637 (stat, lstat): New functions, call 'stat_worker'.
4638 (symlink, readlink, careadlinkat): Rewritten to create and resolve
4639 symlinks when the underlying filesystem supports them.
4641 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
4643 Fix macroexp crash on Windows with debugging (Bug#12118).
4644 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
4645 checking subscripts; problem introduced with the recent
4646 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
4647 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
4648 since it's used in non-static inline functions now.
4650 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
4651 Don't assume buffer size fits in 'int'. Remove unused local.
4653 Use C99-style 'extern inline' if available.
4654 * buffer.h (BUFFER_INLINE):
4655 * category.h (CATEGORY_INLINE):
4656 * character.h (CHARACTER_INLINE):
4657 * charset.h (CHARSET_INLINE):

4662 New macro, replacing 'static inline' in this header.
4663 * buffer.h, category.h, character.h, charset.h, composite.h:
4664 * dispextern.h, lisp.h, systime.h:
4665 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
4666 * alloc.c (LISP_INLINE):
4667 * buffer.c (BUFFER_INLINE):
4668 * category.c (CATEGORY_INLINE):
4669 * character.c (CHARACTER_INLINE):
4670 * charset.c (CHARSET_INLINE):
4671 * composite.c (COMPOSITE_INLINE):
4672 * dispnew.c (DISPEXTERN_INLINE):
4673 * sysdep.c (SYSTIME_INLINE):
4674 Define to EXTERN_INLINE, so that the corresponding functions
4675 are compiled into code.
4676 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
4677 (INLINE_HEADER_END): New macros.
4678 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,
4679 since it's used in non-static inline functions now.

4698 hard-coding the path separator.
4700 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
4702 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
4703 This how ASET and AREF are supposed to work, and makes
4704 it easier to think about future improvements. See
4705 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
4706 * charset.h (set_charset_attr): New function.
4707 All lvalue-style uses of CHARSET_DECODER etc. changed to use it.
4708 * lisp.h (ASET): Rewrite so as not to use AREF in an lvalue style.

5121 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
5122 enumeration constants, as PURE and HEAP are too general, and clash
5123 with other headers and sources, such as gmalloc.c and the
5124 MS-Windows system headers. All users changed.
5126 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
5128 Revert last save_excursion_save and save_excursion_restore changes.
5129 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

5142 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
5143 arms of an 'if', not using conditional expressions; otherwise GDB
5144 complains about the types in the unevaluated arm when the argument
5145 is an integer literal.
5146 (xgetint): Simplify expression.
5147 * alloc.c (gdb_make_enums_visible): New constant. This ports to
5148 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
5149 Zaretskii in <http://bugs.gnu.org/12036#13>.
5150 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
5151 needed now that we have gdb_make_enums_visible.
5152 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
5153 (enum enum_USE_LSB_TAG):
5154 New enum types, packaging up enums that need to be exported to GDB.

5196 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
5197 emacs.c, as this is a more-suitable home. Had this been done earlier
5198 the fix for 12036 would have avoided some of the problems noted in
5199 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
5200 would have been more obvious.
5201 * emacs.c: Do not include <verify.h>; no longer needed.
5202 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
5203 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
5204 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):

5210 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
5211 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
5212 not be usable in #if. This simplifies things.
5214 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
5216 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.

5221 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
5222 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
5223 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
5224 Adjust to changes in lisp.h and emacs.c, by using
5225 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
5226 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
5227 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
5228 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
5229 instead of gdb_valbits.
5230 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
5231 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
5232 instead of gdb_array_mark_flag.
5233 (xboolvector): Get size from $->size, not $->header.size.
5234 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
5235 (xreload, hook-run, hookpost-run): Remove.
5236 * emacs.c: Include <verify.h>.
5237 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
5238 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
5240 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
5241 (gdb_USE_LSB_TAG): New enum constants.
5242 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
5243 Also define these as enum constants, so they're visible to GDB.
5244 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
5245 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
5246 as constants, so they're visible to GDB.

5249 Now enum constants, not macros, so they're visible to GDB.
5250 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
5251 more convenient now. All uses changed.
5252 (VALMASK) [USE_LSB_TAG]: Also define in this case.
5253 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
5255 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

5262 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
5263 add argument, tune behavior, and adjust all callers.
5265 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
5267 Use typedef for EMACS_INT, EMACS_UINT.
5268 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
5269 than macros. This simplifies debugging in the usual case, since
5270 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
5271 and it allows expressions involving EMACS_INT casts.
5272 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
5274 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

5286 Adjust buffer text indirection counters at the end of Fkill_buffer.
5287 * buffer.c (Fkill_buffer): Adjust indirection counters when the
5288 buffer is definitely dead. This should really fix an issue reported
5289 by Christoph Scholtes again. (Bug#12007).
5290 (init_buffer_once): Initialize indirection counters of
5291 buffer_defaults and buffer_local_symbols (for sanity and safety).
5293 2012-07-24 Eli Zaretskii <eliz@gnu.org>
5295 * xdisp.c (init_iterator): Don't compute dimensions of truncation
5296 and continuation glyphs on tooltip frames, leave them at zero.

5324 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
5326 Swap buffer text indirection counters in Fbuffer_swap_text.
5327 * buffer.c (Fbuffer_swap_text): Swap indirections too.
5328 This avoids crash reported by Christoph Scholtes at
5329 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
5331 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
5333 * nsmenu.m (Popdown_data): New struct.
5334 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
5336 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
5337 (initWithContentRect): Make imgView and contentView non-static
5338 and autorelease them. Also autorelease img and matrix (Bug#12005).
5339 (dealloc): Remove (Bug#12005).
5341 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
5343 Adjust consing_since_gc when objects are explicitly freed.

5356 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
5358 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
5359 as it's limited by the amount of memory, not by INT_MAX.
5361 2012-07-21 Eli Zaretskii <eliz@gnu.org>
5363 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
5364 in special-event-map. See the discussion at

6087 * s/aix4-2.h (unix): Remove; no longer needed.
6089 EMACS_TIME simplification (Bug#11875).
6090 This replaces macros (which typically do not work in GDB)
6091 with functions, typedefs and enums, making the code easier to debug.
6092 The functional style also makes code easier to read and maintain.
6093 * systime.h: Include <sys/time.h> on all hosts, not just if
6094 WINDOWSNT, since 'struct timeval' is needed in general.

6110 (add_emacs_time, sub_emacs_time): New functions.
6111 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.

6134 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
6135 Prefer snprintf to strncpy.
6136 * nsterm.m (ns_term_init):
6137 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
6138 * nsterm.m (ns_term_init):
6139 Avoid the need for strncpy, by using build_string or
6140 make_unibyte_string directly. Use dtoastr, not snprintf.
6141 * process.c (Fmake_network_process): Diagnose service names that
6142 are too long, rather than silently truncating them or creating
6143 non-null-terminated names.
6144 (Fnetwork_interface_info): Likewise, for interface names.
6145 * sysdep.c (system_process_attributes) [GNU_LINUX]:
6146 Prefer sprintf to strncat.

6160 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
6161 where argument type is known to be a Lisp_Cons.

6216 O_RDONLY already includes it).
6218 Stop ns builds setting the EMACSLOADPATH environment variable.
6219 * nsterm.m (ns_load_path): Rename from ns_init_paths.
6220 Now it does not set EMACSLOADPATH, just returns the load-path string.

6222 * lread.c [HAVE_NS]: Include nsterm.h.
6223 (init_lread) [HAVE_NS]: Use ns_load_path.

6233 (ns_init_paths): Do not set EMACSPATH.

6293 Move marker debugging code under MARKER_DEBUG.
6294 * marker.c (MARKER_DEBUG): Move marker debugging code under
6295 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
6296 for bootstrap with --enable-checking (~3x slowdown reported

6309 (display_line): Add commentary about displaying truncation glyphs
6311 (produce_special_glyphs): Move here from term.c.
6313 * term.c (produce_special_glyphs): Move to xdisp.c.
6315 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
6318 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
6320 * xdisp.c (display_line): Avoid warning about implicit declaration
6323 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
6325 * lisp.h: Remove empty conditional.
6327 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
6329 * lread.c (load_path_check): Now static.
6331 Fix some minor --with-ns problems found by static checking.
6332 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
6333 (x_set_font) [!HAVE_X_WINDOWS]:
6334 * image.c (xpm_load_image) [HAVE_NS]:
6335 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
6336 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
6337 Remove unused local.
6338 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
6339 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
6340 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
6341 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
6342 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
6343 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
6344 Fix pointer signedness problem.
6345 * xfaces.c (FRAME_X_FONT_TABLE):
6346 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
6348 2012-07-07 Glenn Morris <rgm@gnu.org>
6350 * lread.c (load_path_check): New function, split from init_lread.
6351 (init_lread): Reorganize. Motivation:
6352 If EMACSLOADPATH is set, check/warn about that rather than the
6353 defaults, which we are not going to use. Hence we can remove
6354 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
6355 Don't warn if site-lisp directories are missing.
6356 If not installed, start from a blank load-path, since
6357 PATH_LOADSEARCH refers to the eventual installation directories.
6359 2012-07-07 Eli Zaretskii <eliz@gnu.org>
6361 Support truncation and continuation glyphs on GUI frames, when
6362 fringes are disabled. (Bug#11832)
6363 * xdisp.c (init_iterator): Get dimensions of truncation and
6364 continuation glyphs even if on GUI frames.
6365 Adjust it->last_visible_x on GUI frames when the left or right fringes,
6366 or both, are absent.
6367 (start_display, move_it_in_display_line_to): Handle the case of a
6368 GUI frame without a fringe to display continuation or truncation
6370 (insert_left_trunc_glyphs): Support GUI frames: make sure
6371 truncation glyphs overwrite enough glyphs from the current line to
6372 have sufficient space in pixels.
6373 (display_line): Support truncation and continuation glyphs on GUI
6374 frames. If some spare pixels are left on the line after inserting
6375 the truncation glyphs, fill that space with a stretch glyph of a
6376 suitably computed width.
6378 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
6379 produce_glyphs, to support GUI sessions.
6381 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
6383 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
6385 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
6387 Do not require float-time's arg to fit in time_t (Bug#11825).
6388 This works better on hosts where time_t is unsigned, and where
6389 float-time is applied to the (negative) difference between two times.
6390 * editfns.c (decode_time_components): Last arg is now double *,
6391 not int *, and means to store all the result as a double, without
6392 worrying about whether the seconds part fits in time_t.
6393 All callers changed.
6394 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
6395 All callers changed.
6396 (Ffloat_time): Do not fail merely because the specified time falls
6397 outside of time_t range.
6399 2012-07-07 Glenn Morris <rgm@gnu.org>
6401 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
6402 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
6403 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
6405 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
6407 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
6408 Update dependencies.
6410 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
6412 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
6414 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
6415 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
6416 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
6417 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
6418 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
6419 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
6421 * xfont.c (compare_font_names): Redo to omit the need for casts.
6423 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
6425 * xfns.c (Fx_change_window_property): Doc fix.
6426 * w32fns.c (Fx_change_window_property): Doc fix.
6428 * w32fns.c (Fx_window_property): Accept the same arguments as the
6429 X Windows version. Doc fix.
6430 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
6432 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
6433 Eli Zaretskii <eliz@gnu.org>
6435 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
6436 Windows-specific code from nt/config.nt moved here.
6437 Obsolete settings removed.
6439 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
6441 * process.c: Avoid unnecessary calls to gettime.
6442 (wait_reading_process_output): Don't get the time of day
6443 when gobbling data immediately and not waiting, as there's no need
6444 for it in that case. This removes a FIXME.
6446 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
6448 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
6449 is defined (Bug#11768).
6451 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6453 Fix marker debugging code.
6454 * marker.c (byte_char_debug_check): Do not perform the check
6455 if buffer is not multibyte.
6456 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
6457 Call byte_char_debug_check with correct arguments.
6459 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6461 Compile marker debugging code only if ENABLE_CHECKING is defined.
6462 * marker.c (byte_char_debug_check, count_markers):
6463 Use only if ENABLE_CHECKING is defined.
6464 (byte_debug_flag): Remove.
6465 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
6466 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
6468 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6470 Avoid code repetition in marker-related functions.
6471 * marker.c (attach_marker): New function.
6472 (Fset_marker, set_marker_restricted, set_marker_both)
6473 (set_marker_restricted_both): Use it.
6474 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
6475 Consistently rename charno to charpos.
6476 (marker_position): Add eassert.
6477 (marker_byte_position): Convert to eassert.
6479 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6481 Simplify list operations in unchain_overlay and unchain_marker.
6482 * buffer.c (unchain_overlay): Simplify. Add comment.
6483 * marker.c (unchain_marker): Simplify. Fix comments.
6485 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6487 Introduce fast path for the widely used marker operation.
6488 * alloc.c (build_marker): New function.
6489 * lisp.h (build_marker): New prototype.
6490 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
6491 * composite.c (autocmp_chars): Likewise.
6492 * editfns.c (buildmark): Remove.
6493 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
6494 (save_restriction_save): Use build_marker.
6495 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
6496 * window.c (save_window_save): Likewise.
6498 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6500 Do not use Fdelete_overlay in delete_all_overlays
6501 to avoid redundant calls to unchain_overlay.
6502 * buffer.c (drop_overlay): New function.
6503 (delete_all_overlays, Fdelete_overlay): Use it.
6504 * minibuf.c (get_minibuffer): Fix comment.
6506 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
6508 Port to OpenBSD 5.1 amd64.
6509 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
6510 This is needed for OpenBSD, and should be harmless on all BSD systems.
6511 Also, include <sys/sysctl.h>, as it should be available on all
6512 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
6513 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
6514 use p_pid member, not kp_proc.pid.
6516 2012-07-06 Glenn Morris <rgm@gnu.org>
6518 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
6520 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
6522 More xmalloc and related cleanup.
6523 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
6524 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:
6525 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, fns.c:

6527 * gtkutil.c, image.c, keyboard.c, keymap.c, lread.c, macros.c, menu.c:
6528 * nsfns.m, nsfont.m, nsmenu.m, nsterm.m, print.c, process.c, ralloc.c:
6529 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:
6530 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
6531 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
6533 Omit needless casts involving void * pointers and allocation.
6534 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
6535 as the former is more robust if P's type is changed.
6536 Prefer xzalloc to xmalloc + memset 0.
6537 Simplify malloc-or-realloc to realloc.
6538 Don't worry about xmalloc returning a null pointer.
6539 Prefer xstrdup to xmalloc + strcpy.
6540 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
6542 * keyboard.c (apply_modifiers_uncached): Prefer local array to
6543 alloca of a constant.
6545 2012-07-05 Eli Zaretskii <eliz@gnu.org>
6547 * xdisp.c (display_line): Fix horizontal pixel coordinates when
6548 hscroll is larger than the line width. Fixes long and futile
6549 looping inside extend_face_to_end_of_line (on a TTY) producing
6550 glyphs that are not needed and thrown away.
6552 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
6554 * marker.c (set_marker_restricted_both): Simplify by using
6557 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
6559 * editfns.c (region_limit): Simplify by using clip_to_bounds.
6561 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>

6564 not defined (Bug#11768).
6565 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
6566 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
6567 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
6568 followed by gtk_box_set_homogeneous (Bug#11768).
6569 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
6570 (update_theme_scrollbar_width, xg_create_scroll_bar):
6571 Use gtk_scrollbar_new (Bug#11768).
6572 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
6573 (is_box_type): New function (Bug#11768).
6574 (xg_tool_item_stale_p): Call is_box_type.
6575 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
6576 with default display (Bug#11768).
6578 2012-07-05 Eli Zaretskii <eliz@gnu.org>
6580 * xdisp.c (window_hscroll_limited): New function.
6581 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
6582 coordinates when window's hscroll is set to insanely large
6585 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
6587 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
6588 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
6590 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
6593 * lisp.h (xzalloc): New prototype. Omit needless casts.
6594 * alloc.c (xzalloc): New function. Omit needless casts.
6595 * charset.c: Omit needless casts. Convert all calls to
6596 xmalloc with following memset to xzalloc.

6646 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
6648 * fileio.c (time_error_value): Check the right error number.
6649 Problem reported by Troels Nielsen in
6650 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
6652 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
6654 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
6655 This should be fixed in a better way; see Eli Zaretskii in
6656 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
6657 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
6659 * fileio.c (time_error_value): Rename from special_mtime.
6660 The old name's problems were noted by Eli Zaretskii in
6661 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
6663 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
6664 This variable's comment says Emacs needs at least one GDB-visible
6665 symbol of type enum pvec_type, to work around GDB problems.
6666 The symbol's value doesn't matter.
6668 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
6669 that causes compilation to fail on pre-C99 compilers.
6671 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
6673 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
6674 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
6676 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
6678 * buffer.c (init_buffer_once): Fix initialization of
6679 headers for buffer_defaults and buffer_local_symbols.
6680 Reported by Juanma Barranquero <lekktu@gmail.com>.
6682 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
6684 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
6685 * lisp.h (enum pvec_type): Use fewer bits.
6686 (PSEUDOVECTOR_SIZE_BITS): New constant.
6687 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
6688 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
6689 change in pvec_type.
6690 (PSEUDOVECTOR_TYPEP): New macro.
6691 (TYPED_PSEUDOVECTORP): Use it.
6692 * fns.c (internal_equal): Adapt code to extract pvectype.
6693 * emacs.c (gdb_pvec_type): Update type.
6694 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
6695 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
6696 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
6697 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
6698 (sweep_vectors): Use it. Use local var `total_bytes' instead of
6699 abusing vector->header.next.nbytes.
6700 (live_vector_p): Use PVEC_TYPE.
6701 (mark_object): Adapt code to extract pvectype. Use switch.
6703 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
6705 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
6706 Tighten new eassert a bit.
6708 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
6710 Fix compilation with --enable-gcc-warnings and -O1
6712 * doprnt.c (doprnt): Change type of tem to int, initialize
6713 to avoid compiler warning. Add eassert.
6714 * search.c (simple_search): Initialize match_byte to avoid
6715 compiler warning. Add eassert.
6717 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
6719 Avoid weird behavior with large horizontal scrolls.
6720 Without this change, for example, large hscroll values would
6721 mess up Emacs's display on Fedora 15 x86, presumably due to
6722 overflows in int calculations in the display code.
6723 Also, if buffers had long lines, Emacs would freeze.
6724 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
6725 (set_window_hscroll): New function, containing the old guts of
6726 Fset_window_hscroll. Return the clipped value.
6727 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
6728 This avoids the need to check against PTRDIFF_MAX.
6730 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
6732 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
6734 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
6736 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
6738 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
6739 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
6740 since GCC 4.4.6 issues a bogus warning for them.
6742 Fix bugs in file timestamp newness comparisons.
6743 * fileio.c (Ffile_newer_than_file_p):
6744 * lread.c (Fload): Use full timestamp resolution of files,
6745 not just the 1-second resolution, so that files that are only
6746 slightly newer still count as newer.
6747 * fileio.c (Ffile_newer_than_file_p): Don't assume file
6748 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
6750 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
6752 * fileio.c: Improve handling of file time marker. (Bug#11852)
6753 (special_mtime): New function.
6754 (Finsert_file_contents, Fverify_visited_file_modtime):
6755 Use it to set special mtime values consistently.
6757 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
6759 * fileio.c (Finsert_file_contents): Properly handle st_mtime
6760 marker for non-existing file. (Bug#11852)
6762 2012-07-03 Glenn Morris <rgm@gnu.org>
6764 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
6765 and did not make it into globals.h).
6767 2012-07-03 Tom Tromey <tromey@redhat.com>
6769 * window.c (Fset_window_margins, Fset_window_fringes)

6814 values which aren't power of 2.
6815 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
6816 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
6819 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
6821 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.

6825 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
6827 * alloc.c (allocate_vector_block): Remove redundant
6828 calls to mallopt if DOUG_LEA_MALLOC is defined.
6829 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
6830 avoid calls to mallopt if zero_vector is returned.
6832 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
6834 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
6835 is enabled, avoid dereferencing NULL current_sblock if
6838 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
6840 Cleanup basic buffer management.
6841 * buffer.h (struct buffer): Change layout to use generic vector
6842 marking code. Fix some comments. Change type of 'clip_changed'
6843 to bitfield. Remove unused #ifndef old.
6844 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
6845 (GET_OVERLAYS_AT): Fix indentation.
6846 (for_each_per_buffer_object_at): New macro.

6850 * alloc.c (allocate_buffer): Adjust to match new layout of
6851 struct buffer. Fix comment.
6852 (mark_overlay): New function.

6854 Lisp area of struct buffer.
6855 (mark_object): Use it. Adjust marking of misc objects
6856 and related comments.
6858 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
6860 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
6861 wrapper that is not needed because the wrapped code is a no-op (zero
6862 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
6863 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
6865 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
6867 * alloc.c (mark_buffer): Simplify. Remove prototype.
6868 (mark_object): Add comment. Reorganize marking of vector-like
6869 objects. Use CHECK_LIVE for all vector-like objects except buffers
6870 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
6871 Avoid redundant calls to mark_vectorlike for bool vectors.
6873 2012-06-30 Glenn Morris <rgm@gnu.org>
6875 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
6877 * epaths.in (PATH_SITELOADSEARCH): New.
6878 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
6879 This is rather than relying on --enable-locallisppath elements
6880 having "site-lisp" in their names. (Bug#10208#25, 11658)
6882 2012-06-30 Eli Zaretskii <eliz@gnu.org>
6884 * w32proc.c (sys_select): Accept and ignore one more argument.
6886 * w32.c (emacs_gnutls_pull): Call select with one more argument.
6888 * sysselect.h [DOS_NT]: Don't include sys/select.h.
6889 (pselect) [!MS_DOS]: Redirect to sys_select.
6891 * sysdep.c: Don't include dos.h and dosfns.h.
6893 * process.c (sys_select):
6894 * msdos.c (sys_select): Accept one more argument and ignore it.
6896 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
6897 adapt data types and code to that.
6900 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
6901 which clashes with the gnulib function of the same name.
6903 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
6905 * font.c (font_style_to_value, font_style_symbolic)
6906 (font_prop_validate_style): Add type checks for values in
6909 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
6911 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
6914 2012-06-29 Eli Zaretskii <eliz@gnu.org>
6916 * xdisp.c (try_window_id): Undo last change.
6918 * w32.c (getwd): Adjust commentary about startup_dir.
6919 (init_environment): Always call sys_access, even in non-MSVC
6920 builds. Don't chdir to the directory of the Emacs executable.
6921 This undoes code from 1997 which was justified by the need to
6922 "avoid conflicts when removing and renaming directories". But its
6923 downside was that every relative file name was being interpreted
6924 relative to the directory of the Emacs executable, which can never
6925 be TRT. In particular, it broke sys_access when called with
6926 relative file names.
6927 (sys_access): Map GetLastError to errno.
6929 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
6931 * window.h (struct window): Change type of 'fringes_outside_margins'

6935 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
6938 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>

6951 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
6953 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
6954 undefined. Convert from xassert to eassert.
6955 * nsmenu.m: Convert from xassert to eassert.

6962 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
6964 Avoid integer overflow on scroll-left and scroll-right.
6965 * window.c (HSCROLL_MAX): New macro.
6966 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer

6971 * window.h (struct window): Change type of 'hscroll',
6972 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
6973 'last_modified' and 'last_overlay_modified' to EMACS_INT.
6974 Adjust users accordingly.
6975 * xdisp.c (try_cursor_movement): Replace type check with eassert.
6976 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
6977 from EMACS_INT to ptrdiff_t.

7053 * alloc.c (allocate_string): Omit intervals initialization.
7054 * alloc.c (make_uninit_multibyte_string): Initialize intervals

7113 a better opportunity to optimize away calls to strlen when the

7119 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
7121 Use sprintf return value instead of invoking strlen on result.
7122 In the old days this wasn't portable, since some sprintf
7123 implementations returned char *. But they died out years ago and
7124 Emacs already assumes sprintf returns int.
7125 Similarly for float_to_string.
7126 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

7133 * xfns.c (syms_of_xfns):
7134 Use sprintf or float_to_string result to avoid need to call strlen.
7135 * data.c (Fnumber_to_string):
7136 Use make_unibyte_string, since the string must be ASCII.
7137 * lisp.h, print.c (float_to_string): Now returns int length.
7138 * term.c (produce_glyphless_glyph):
7139 Use sprintf result rather than recomputing it.
7141 Clean out last vestiges of the old HAVE_CONFIG_H stuff.

7174 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

7177 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
7179 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
7180 instead of truncating it to 63 (admittedly a generous limit).
7182 * process.c: Fix spelling and caps in comments.
7184 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>

7240 * keyboard.c (kbd_buffer_get_event):

7263 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
7264 Privately reported by Herbert J. Skuhra.
7265 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
7267 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,

7276 language ID in the event parameters.
7278 * w32term.c (w32_read_socket): Put the new keyboard codepage into

7302 * sysdep.c [__FreeBSD__]: Fix recently-introduced typos.
7303 Privately reported by Herbert J. Skuhra.
7304 [__FreeBSD__]: Remove "*/" typo after "#include".
7305 (timeval_to_EMACS_TIME) [__FreeBSD__]: New static function.
7306 (TIMEVAL) [__FreeBSD__]: Now a static function rather than a macro.
7307 (TIMEVAL, system_process_attributes) [__FreeBSD__]:
7308 Don't assume EMACS_TIME and struct timeval are the same type.
7310 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
7312 Support higher-resolution time stamps (Bug#9000).
7313 The time stamps are only nanosecond-resolution at the C level,
7314 since that's the best that any real-world system supports now.
7315 But they are picosecond-resolution at the Lisp level, as that's
7316 easy, and leaves room for future OS improvements.
7318 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
7321 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
7322 Don't get current time unless it's needed.
7324 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
7325 now provides it if it's absent.
7326 (start_atimer): Port to higher-res time stamps.
7327 Check for time stamp overflow. Don't get current time more
7328 often than is needed.
7330 * buffer.h (struct buffer): Buffer modtime now has high resolution.
7331 Include systime.h, not time.h.
7332 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
7334 * dired.c: Include stat-time.h.
7335 (Ffile-attributes): File times now have higher resolution.

7338 (struct image): Timestamp now has higher resolution.
7340 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
7341 has at least microseconds now. All uses removed.
7342 (update_frame, update_single_window, update_window, update_frame_1)
7343 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
7344 (duration_to_sec_usec): Remove; no longer needed.
7346 * editfns.c (time_overflow): Now extern.

7352 (decode_time_components, lisp_seconds_argument): New functions.
7353 (make_time): Now static.
7354 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
7355 Report an error if the time is invalid, rather than having the caller
7358 * fileio.c: Include <stat-time.h>
7359 (Fcopy_file): Copy higher-resolution time stamps.
7360 Prefer to set the time stamp via a file descriptor if that works.

7362 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
7363 (Fvisited_file_modtime, Fset_visited_file_modtime):
7364 Support higher-resolution time stamps.
7366 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
7368 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
7370 * image.c (prepare_image_for_display, clear_image_cache)
7371 (lookup_image): Port to higer-resolution time stamps.
7373 * keyboard.c (start_polling, bind_polling_period):
7374 Check for time stamp overflow.
7375 (read_char, kbd_buffer_get_event, timer_start_idle)
7376 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
7377 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
7378 Port to higher-resolution time stamps. Do not assume time_t is signed.
7379 (decode_timer): New function. Timers are now vectors of length 9,
7380 not 8, to accommodate the picosecond component.
7381 (timer_check_2): Use it.
7383 * nsterm.m (select_timeout, timeval_subtract): Remove.
7384 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
7385 as they're a bit more accurate and handle overflow better.
7386 (ns_select): Change prototype to be compatible with pselect.
7387 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
7388 * nsterm.h (ns_select): Adjust prototype.
7390 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
7391 us-resolution time stamps.
7392 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
7394 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
7396 * lisp.h (time_overflow): New decl.
7397 (wait_reading_process_output): First arg is now intmax_t, not int,
7398 to accommodate larger waits.
7400 * process.h (struct Lisp_Process.read_output_delay):
7401 Now counts nanoseconds, not microseconds.
7402 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
7404 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
7405 (wait_reading_process_output):
7406 Port to ns-resolution time stamps.
7407 (Faccept_process_output, wait_reading_process_output):
7408 Check for time stamp overflow. Do not assume time_t is signed.
7409 (select_wrapper): Remove; we now use pselect.
7410 (Fprocess_attributes): Now generates ns-resolution time stamps.
7412 * sysdep.c: Include utimens.h. Don't include utime.h
7413 or worry about struct utimbuf; gnulib does that for us now.
7414 (gettimeofday): Remove; gnulib provides a substitute.
7415 (make_timeval): New function.
7416 (set_file_times): Now sets ns-resolution time stamps.
7417 New arg FD; all uses changed.
7418 (time_from_jiffies, ltime_from_jiffies, get_up_time)
7419 (system_process_attributes):
7420 Now returns ns-resolution time stamp. All uses changed.
7421 Check for time stamp overflow.
7423 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
7424 provides a substitute now.
7426 * systime.h: Include timespec.h rather than sys/time.h and time.h,
7427 since it guarantees struct timespec.
7428 (EMACS_TIME): Now struct timespec, so that we can support
7429 ns-resolution time stamps.
7430 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
7431 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
7432 (EMACS_USECS): Remove.
7433 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
7434 so multiply the arg by 1000 before storing it.
7435 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
7437 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
7438 Port to ns-resolution time stamps.
7439 (EMACS_TIME_NEG_P): Remove; replaced by....
7440 (EMACS_TIME_SIGN): New macro.
7441 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
7442 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
7443 (set_file_times, make_time, lisp_time_argument): Adjust signature.
7444 (make_timeval, make_lisp_time, decode_time_components): New decls.
7445 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
7446 that it mishandled time_t overflow. You can't compare by subtracting!
7447 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
7448 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
7450 * term.c: Include <sys/time.h>.
7451 (timeval_to_Time): New function, for proper overflow wraparound.
7452 (term_mouse_position, term_mouse_click): Use it.
7454 * undo.c (record_first_change): Support higher-resolution time stamps
7456 (Fprimitive_undo): Use them when restoring time stamps.
7458 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
7459 (w32_get_internal_run_time):
7460 Port to higher-resolution Emacs time stamps.
7461 (ltime): Now accepts single 64-bit integer, as that's more convenient
7464 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
7466 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
7467 for compatibility with pselect. Support ns-resolution time stamps.
7469 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
7471 * xselect.c (wait_for_property_change, x_get_foreign_selection):
7472 Check for time stamp overflow, and support ns-resolution time stamps.
7474 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
7475 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
7476 (timeval_subtract): Remove; no longer needed.
7477 (XTflash, XTring_bell, x_wait_for_event):
7478 Port to ns-resolution time stamps. Don't assume time_t is signed.
7480 2012-06-22 Chong Yidong <cyd@gnu.org>

7484 2012-06-22 Eli Zaretskii <eliz@gnu.org>
7486 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
7487 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
7488 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
7489 staticidx goes up to 1597 out of 1600 = 0x640.)
7491 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
7493 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
7494 Otherwise, the umask might be mistakenly 0 while handling input signals.

7516 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
7518 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,

7527 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
7528 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
7529 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
7530 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.

7537 2012-06-18 Martin Rudalics <rudalics@gmx.at>
7539 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
7540 gets killed during executing of this function (Bug#11665).
7541 Try to always return Qt when the buffer has been actually killed.
7542 (Vkill_buffer_query_functions): In doc-string say that functions
7543 run by this hook should not change the current buffer.
7545 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
7547 Fix recently-introduced process.c problems found by static checking.

7565 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
7567 * lisp.h (eassert): Assume C89 or later.
7568 This removes the need for CHECK.
7569 (CHECK): Remove. Its comments about always evaluating its
7570 argument were confusing, as 'eassert' typically does not evaluate
7573 * coding.c (produce_chars): Use ptrdiff_t, not int.
7575 * xterm.c (x_draw_underwave): Check for integer overflow.
7576 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

7743 Remove define/undef of HAVE_SYSV_SIGPAUSE (not used since 2010-05-04).
7745 * s/gnu.h (POSIX_SIGNALS): Remove (not used since 2010-05-04).
7747 2012-06-13 Paul Eggert <eggert@cs.ucla.edu>
7749 USE_LISP_UNION_TYPE + USE_LSB_TAG cleanup (Bug#11604)
7750 * alloc.c (make_number) [!defined make_number]:
7751 Remove, as lisp.h always defines this now.
7752 (mark_maybe_pointer): Simplify since USE_LSB_TAG is always defined now.
7753 (roundup_size): Verify that it is a power of 2.
7754 * data.c (Fmake_variable_buffer_local, Fmake_local_variable):
7755 * ftfont.c (ftfont_driver): Use LISP_INITIALLY_ZERO.
7756 * lisp.h (USE_LSB_TAG): Allow the builder to compile with
7757 -DUSE_LSB_TAG=0, to override the automatically-selected default.
7758 USE_LSB_TAG now is always defined to be either 0 or 1.
7760 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
7761 code works fine either way, and efficiency is not a concern here,
7762 as the union type is for debugging, not for production.
7763 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
7764 Use an inline function on all platforms when using the union type,
7765 since this is simpler and 'static inline' can be used portably
7767 (LISP_INITIALLY_ZERO): New macro.
7768 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
7769 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.
7771 2012-06-12 Glenn Morris <rgm@gnu.org>

7786 MagickMergeImageLayers is undefined. Use pixel pusher loop if
7787 MagickExportImagePixels is undefined.

7791 * image.c (imagemagick_load_image): Remove unused label.
7793 2012-06-11 Glenn Morris <rgm@gnu.org>
7795 * s/aix4-2.h, s/bsd-common.h, s/cygwin.h, s/darwin.h:
7796 * s/gnu-kfreebsd.h, s/gnu-linux.h, s/gnu.h, s/hpux10-20.h:
7797 * s/irix6-5.h, s/ms-w32.h, s/msdos.h, s/template.h:
7798 * s/usg5-4-common.h: Move SYSTEM_TYPE to configure.
7800 2012-06-11 Stefan Monnier <monnier@iro.umontreal.ca>
7802 * alloc.c (make_byte_code): New function.

7808 * image.c (imagemagick_load_image): Implement transparency.
7810 2012-06-10 Andreas Schwab <schwab@linux-m68k.org>

7835 2012-06-09 Michael Albinus <michael.albinus@gmx.de>
7837 * dbusbind.c (XD_BASIC_DBUS_TYPE): Use dbus_type_is_valid and
7838 dbus_type_is_basic if available.
7839 (xd_extract_signed, xd_extract_unsigned): Rename from
7840 extract_signed and extract_unsigned, respectively. Adapt callers.
7842 2012-06-09 Chong Yidong <cyd@gnu.org>
7844 * xfaces.c (face_for_overlay_string): Handle face remapping (Bug#2066).
7846 * fringe.c (Fset_fringe_bitmap_face): Handle the noninteractive
7849 2012-06-08 Paul Eggert <eggert@cs.ucla.edu>
7851 * xdisp.c (vmessage): Treat frame message as multibyte.
7852 Without this change, (let ((§ 1)) (make-variable-buffer-local '§))
7853 would generate the diagnostic "Making \302\247 buffer-local while
7856 2012-06-08 Eli Zaretskii <eliz@gnu.org>
7858 * dispnew.c (showing_window_margins_p): Undo last change, which

7869 2012-06-08 Juanma Barranquero <lekktu@gmail.com>
7871 * dispnew.c (showing_window_margins_p): Wrap in #if 0 to prevent unused
7872 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
7874 2012-06-08 Eli Zaretskii <eliz@gnu.org>
7876 * alloc.c (allocate_vectorlike): Fix last change.
7878 2012-06-08 Dmitry Antipov <dmantipov@yandex.ru>
7880 Block-based vector allocation of small vectors.
7881 * lisp.h (struct vectorlike_header): New field `nbytes',
7882 adjust comment accordingly.
7883 * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'
7884 to denote vector blocks. Adjust users (live_vector_p,
7885 mark_maybe_pointer, valid_lisp_object_p) accordingly.

7887 (VECTOR_BLOCK_SIZE, vroundup, VECTOR_BLOCK_BYTES),
7888 (VBLOCK_BYTES_MIN, VBLOCK_BYTES_MAX, VECTOR_MAX_FREE_LIST_INDEX),
7889 (VECTOR_FREE_LIST_FLAG, ADVANCE, VINDEX, SETUP_ON_FREE_LIST),
7890 (VECTOR_SIZE, VECTOR_IN_BLOCK): New macros.

7905 * eval.c (Fmacroexpand): Stop if the macro returns the same form.
7907 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
7909 * doprnt.c (doprnt): Truncate multibyte char correctly.
7910 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
7911 would mishandle a string argument "Xc" if X was a multibyte
7912 character of length 2: it would truncate after X's first byte
7913 rather than including all of X.
7915 2012-06-06 Chong Yidong <cyd@gnu.org>
7917 * buffer.c (word_wrap): Doc fix.
7919 2012-06-04 Paul Eggert <eggert@cs.ucla.edu>

7964 * minibuf.c (Fassoc_string): Remove duplicate declaration.
7966 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
7967 Convert pctcpu and pctmem to Lisp float properly.
7968 Let the compiler fold better, as 100.0/0x8000 is exact.
7970 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
7972 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
7975 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
7977 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
7979 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
7981 For a 'struct window', replace some Lisp_Object fields to
7982 bitfields where appropriate, remove unused fields.
7983 * window.h (struct window): Remove unused 'last_mark_x' and
7984 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
7985 change its type from Lisp_Object to bitfield.
7986 Change type of 'force_start', 'optional_new_start',
7987 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
7988 fields from Lisp_Object to bitfield. Adjust users accordingly.
7990 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
7992 Pacify gcc -Wdouble-precision when using Xaw.
7993 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
7994 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
7995 Use 'float' consistently, rather than 'float' in most places
7996 and 'double' in a couple of places.
7998 2012-05-31 Eli Zaretskii <eliz@gnu.org>
8000 * xdisp.c (handle_stop): Detect whether we have overlay strings
8001 loaded by testing it->current.overlay_string_index to be
8002 non-negative, instead of checking whether n_overlay_strings is
8003 positive. (Bug#11587)
8005 2012-05-31 Chong Yidong <cyd@gnu.org>
8007 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
8009 * doc.c (Fsubstitute_command_keys): Doc fix.
8011 2012-05-31 Eli Zaretskii <eliz@gnu.org>
8013 * search.c (search_buffer): Remove calls to
8014 r_alloc_inhibit_buffer_relocation, as it is now called by
8015 maybe_unify_char, which was the cause of relocation of buffer text
8018 2012-05-31 Eli Zaretskii <eliz@gnu.org>
8020 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
8021 for the duration of call to load_charset, to avoid problems with
8022 callers of maybe_unify_char that access buffer text through C
8025 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
8026 decrement the inhibition flag, instead of just setting or
8029 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
8031 Remove obsolete '#define static' cruft.
8032 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
8033 This #undef was "temporary" in 2000; it is no longer needed
8034 now that '#define static' has gone away.
8035 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
8036 (gray_bitmap_bits): Remove; no longer needed.
8037 All uses replaced with definiens.
8038 * xterm.c: Include "bitmaps/gray.xbm".
8040 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
8042 Clean up __executable_start, monstartup when --enable-profiling.
8043 The following changes affect the code only when profiling.
8044 * dispnew.c (__executable_start): Rename from safe_bcopy.
8045 Define only on platforms that need it.
8046 * emacs.c: Include <sys/gmon.h> when profiling.
8047 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
8048 (__executable_start): Remove decl, since lisp.h does it now.
8049 (safe_bcopy): Remove decl; no longer has that name.
8050 (main): Coalesce #if into single bit of code, for simplicity.
8051 Cast pointers to uintptr_t, since standard libraries want integers

8055 2012-05-31 Glenn Morris <rgm@gnu.org>
8057 * image.c (Fimagemagick_types): Doc fix.

8075 * lisp.h (Qdefun): Remove.
8076 * lread.c (read1): Tiny simplification.
8078 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
8080 Do not create empty overlays with the evaporate property (Bug#9642).
8081 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
8082 Bug#9642, but explicitly check that the buffer the overlay would
8083 be moved to is live and rearrange lines to make sure that errors
8084 will not put the overlay in an inconsistent state.
8085 (Fdelete_overlay): Cosmetics.
8087 2012-05-28 Eli Zaretskii <eliz@gnu.org>
8089 * w32term.c (my_bring_window_to_top): New function.
8090 (x_raise_frame): Use handle returned by DeferWindowPos, which
8091 could be different from the original one.
8092 Call my_bring_window_to_top instead of my_set_foreground_window.
8095 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
8096 by calling BringWindowToTop.

8101 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
8103 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
8104 This avoids undefined behavior that might cause the eassert
8105 to not catch an out-of-range value.
8107 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
8109 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

8119 when referring to sectname field in printf format.
8121 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
8123 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
8124 Only r_alloc_inhibit_buffer_relocation needed to be added;
8125 the others were already declared.
8127 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
8128 before checking whether it's out of range. Put the check inside
8130 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
8132 2012-05-27 Ken Brown <kbrown@cornell.edu>
8134 * callproc.c (Fcall_process): Restore a line that was accidentally
8135 commented out in the 2011-02-13 change (bug#11547).

8139 * lisp.h [REL_ALLOC]: Add prototypes for external functions
8140 defined on ralloc.c.
8142 * buffer.c [REL_ALLOC]: Remove prototypes of
8143 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
8144 they are now on lisp.h.
8146 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
8148 * search.c (search_buffer): Use it to inhibit relocation of buffer
8149 text while re_search_2 is doing its job, because re_search_2 is
8150 passed C pointers to buffer text. (Bug#11519)
8152 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
8155 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
8156 state after an additional call to move_it_in_display_line_to, keep
8157 the values of it->max_ascent and it->max_descent found for the
8159 (pos_visible_p): Revert the comparison against bottom_y to what it
8160 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
8163 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
8165 Fix coding-related core dumps with gcc -ftrapv.
8166 The code was computing A - B, where A and B are pointers, and B is
8167 random garbage. This can lead to core dumps on platforms that
8168 have special pointer registers, and it also leads to core dumps on
8169 x86-64 when compiled with gcc -ftrapv. The fix is to compute
8170 A - B only when B is initialized properly.
8171 * coding.c (coding_set_source, coding_set_destination): Return void.
8172 (coding_change_source, coding_change_destinations): New functions,
8173 with the old behaviors of coding_set_source and coding_set_destination.
8174 All callers that need an offset changed to use these new functions.
8176 2012-05-26 Glenn Morris <rgm@gnu.org>
8178 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
8180 2012-05-26 Eli Zaretskii <eliz@gnu.org>
8182 Extend mouse support on W32 text-mode console.
8183 * xdisp.c (draw_row_with_mouse_face):
8184 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
8186 * w32console.c: Include window.h.
8187 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
8189 (initialize_w32_display): Initialize mouse-highlight data.
8191 * w32inevt.c: Include termchar.h and window.h.
8192 (do_mouse_event): Support mouse-autoselect-window. When the mouse
8193 moves, call note_mouse_highlight. If help_echo changed, call
8194 gen_help_event to produce help-echo message in the echo area.
8195 Call clear_mouse_face if mouse_face_hidden is set in the mouse
8198 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
8200 * lread.c (read1): Simplify slightly to avoid an overflow warning
8201 with GCC 4.7.0 on x86-64.
8203 2012-05-26 Eli Zaretskii <eliz@gnu.org>
8205 * bidi.c (bidi_mirror_char): Revert last change: an int is
8206 definitely wide enough here.
8208 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
8210 Fix integer width and related bugs (Bug#9874).
8211 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
8212 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
8213 (string_bytes, check_sblock, allocate_string_data):
8214 (compact_small_strings, Fmake_bool_vector, make_string)
8215 (make_unibyte_string, make_multibyte_string)
8216 (make_string_from_bytes, make_specified_string)

8244 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8245 (validate_region): Omit unnecessary test for b <= e,
8246 since that's guaranteed by the previous test.

8248 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
8249 (report_overlay_modification):

8251 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):

8260 not int, to avoid needless 32-bit limit on 64-bit hosts.
8261 (exec_byte_code): Use tighter memory-full test, one that checks
8262 for alloca overflow. Don't compute the address of the object just
8263 before an array, as that's not portable. Use EMACS_INT, not
8264 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
8265 * callint.c (Fcall_interactively):
8266 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

8279 (casify_object): Avoid integer overflow when overallocating buffer.
8280 * casetab.c (set_identity, shuffle): Prefer int to unsigned when

8283 * category.h (CATEGORYP): Don't assume arg is nonnegative.
8284 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the

8287 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8288 For CCL_MapSingle, check that content and value are in int range.

8290 Check that Vcode_version_map_vector is a vector.
8291 (resolve_symbol_ccl_program): Check that vector header is in range.
8292 Always copy the vector, so that we can check its contents reliably
8293 now rather than having to recheck each instruction as it's being
8294 executed. Check that vector words fit in 'int'.
8295 (ccl_get_compiled_code, Fregister_ccl_program)
8296 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
8297 program indexes, to avoid needless 32-bit limit on 64-bit hosts.

8299 contents are in range.
8300 (Fccl_execute_on_string): Check that status is in range.
8301 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
8302 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
8303 Accept and return EMACS_INT, not int, because callers can pass values

8312 avoid mishandling large integers.

8323 Don't rely on undefined behavior with signed left shift overflow.
8324 Don't assume unsigned int fits into fixnum, or that fixnum fits
8325 into unsigned int. Don't require max_code to be a valid fixnum;
8326 that's not true for gb10830 4-byte on a 32-bit host. Allow
8327 invalid_code to be a cons, for the same reason. Require code_offset
8328 to be a character. Avoid int overflow if max_char is close
8330 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
8331 this is intended anyway and avoids some undefined behavior.
8332 (load_charset_map): Pass unsigned, not int, as 2nd arg of
8333 INDEX_TO_CODE_POINT, as that's what it expects.
8334 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
8335 * charset.h (DECODE_CHAR): Return int, not unsigned;
8336 this is what was intended anyway, and it avoids undefined behavior.
8337 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
8338 integer-overflow issues.
8339 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
8340 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
8341 where the argument is EMACS_INT, and this behavior is not intended.
8342 * chartab.c (Fmake_char_table, Fset_char_table_range)
8343 (uniprop_get_decoder, uniprop_get_encoder):
8344 Don't assume fixnum fits in int.
8345 * cmds.c (move_point): New function, that does the gist of
8346 Fforward_char and Fbackward_char, but does so while checking
8347 for integer overflow more accurately.
8348 (Fforward_char, Fbackward_char): Use it.
8349 (Fforward_line, Fend_of_line, internal_self_insert)
8350 (internal_self_insert):
8351 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

9010 2012-05-25 Glenn Morris <rgm@gnu.org>
9012 * lisp.mk (lisp): Update for more files being compiled now.
9014 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>
9016 * lread.c: Remove `read_pure' which makes no difference.
9017 (read_pure): Remove var.
9018 (unreadpure): Remove function.
9019 (readevalloop): Don't call read_list with -1 flag.

9032 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
9034 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
9037 This directory predates autoconf and is no longer needed nowadays.
9038 Move its few remaining bits of functionality to where they're needed.
9039 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:

9048 (EMACS_UINT): Define unconditionally now.
9049 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
9050 (BITS_PER_EMACS_INT): New constants, replacing
9051 what used to be in config.h, but not useful in #if.
9052 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
9053 define them any more.
9054 (VAL_MAX): New macro.
9056 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
9057 BITS_PER_EMACS_INT, in #if.
9058 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
9059 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
9060 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
9061 * s/ms-w32.h (DATA_START):
9062 Move here from removed file m/intel386.h.
9063 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
9064 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
9066 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
9068 Assume C89 or later.
9069 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.

9077 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
9078 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
9079 * xterm.c (input_signal_count): Assume volatile works.
9081 2012-05-21 Ken Brown <kbrown@cornell.edu>
9083 * xgselect.c (xg_select): Fix first argument in call to 'select'
9086 2012-05-20 Ken Brown <kbrown@cornell.edu>
9088 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
9089 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
9091 2012-05-19 Ken Brown <kbrown@cornell.edu>
9093 * xfns.c (x_in_use): Remove `static' qualifier.
9094 * xterm.h (x_in_use): Declare.
9095 * xgselect.c: Include xterm.h.
9096 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
9097 and `display_arg' (bug#9754).
9099 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
9101 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
9103 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
9104 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
9106 2012-05-18 Eli Zaretskii <eliz@gnu.org>
9108 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
9110 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
9111 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
9113 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
9114 reference to image_cache->refcount.
9115 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
9117 2012-05-17 Juri Linkov <juri@jurta.org>
9119 * search.c (Fword_search_regexp, Fword_search_backward)
9120 (Fword_search_forward, Fword_search_backward_lax)
9121 (Fword_search_forward_lax): Move functions to isearch.el
9122 (bug#10145, bug#11381).
9124 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
9126 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
9128 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
9130 * lread.c (init_obarray): Declare Qt and Qnil as special.
9132 2012-05-14 Glenn Morris <rgm@gnu.org>
9134 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
9135 Put "libexec" before "bin", for the sake of init_callproc_1.
9137 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
9139 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
9141 * unexaix.c: Port to more-recent AIX compilers.
9142 (report_error, report_error_1, make_hdr, copy_sym)
9143 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
9144 Make arguments const char *, not char *, to avoid violations of C
9145 standard and to fix some AIX warnings reported by Gilles Pion.
9147 2012-05-14 Eli Zaretskii <eliz@gnu.org>
9149 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
9150 already have overlays loaded.
9151 (handle_single_display_spec): Before returning without displaying
9152 fringe bitmap, synchronize the bidi iterator with the main display
9153 iterator, by calling iterate_out_of_display_property.
9154 (iterate_out_of_display_property): Detect buffer iteration by
9155 testing that it->string is a Lisp string.
9156 (get_next_display_element): When the current object is exhausted,
9157 and there's something on it->stack, call set_iterator_to_next to
9158 proceed with what's on the stack, instead of returning zero.
9159 (set_iterator_to_next): If called at the end of a Lisp string,
9160 proceed to consider_string_end without incrementing string
9161 position. Don't increment display vector index past the end of
9162 the display vector. (Bug#11417)
9163 (pos_visible_p): Don't report a position visible when move_it_to
9164 stopped at the last line of window, which happens to be scanned
9165 backwards by the bidi iteration. (Bug#11464)
9167 2012-05-14 Eli Zaretskii <eliz@gnu.org>
9169 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
9170 and right-margin display specs even if the spec is invalid or we
9171 are on a TTY, and thus unable to display on the fringes.
9172 That's because the text with the property will not be displayed anyway,
9173 so we need to signal to the caller that this is a "replacing"
9174 display spec. This fixes display when the spec is invalid or we
9177 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
9179 * unexaix.c (make_hdr): Fix typo in prototype.
9180 This bug broke the build on AIX. Problem reported by Gilles Pion.
9182 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
9184 * keyboard.c (kbd_buffer_get_event): Read special events also in
9185 batch mode. (Bug#11415)
9187 2012-05-12 Glenn Morris <rgm@gnu.org>
9189 * ns.mk: Update for ns_appbindir no longer having trailing "/".
9191 2012-05-12 Eli Zaretskii <eliz@gnu.org>
9193 * lisp.mk (lisp): Add newcomment.elc.
9195 2012-05-12 Glenn Morris <rgm@gnu.org>
9197 * Makefile.in (MKDIR_P): New, set by configure.
9198 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
9200 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
9202 Remove unused function hourglass_started.
9203 * dispextern.h (hourglass_started):
9204 * w32fns.c (hourglass_started):
9205 * xdisp.c (hourglass_started): Remove.
9207 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
9209 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
9210 Update dependencies.
9212 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
9214 * xgselect.c (xg_select): Put maxfds+1 into a var.
9215 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
9217 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
9219 2012-05-10 Dave Abrahams <dave@boostpro.com>
9221 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
9222 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
9224 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
9226 * dbusbind.c (xd_registered_buses): New internal Lisp object.
9227 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
9228 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
9229 Initialize xd_registered_buses.
9231 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
9233 Untag more efficiently if USE_LSB_TAG.
9234 This is based on a proposal by YAMAMOTO Mitsuharu in
9235 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
9236 For an admittedly artificial (nth 8000 longlist) benchmark on
9237 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
9238 Emacs's overall text size by 1%.
9239 * lisp.h (XUNTAG): New macro.
9240 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
9241 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
9242 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
9243 * eval.c (Fautoload):
9244 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
9245 * frame.h (XFRAME): Use XUNTAG.
9247 Port recent dbusbind.c changes to 32-bit --with-wide-int.
9248 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
9249 Remove unportable assumptions about print widths of types like
9251 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
9252 intptr_t when converting between pointer and integer, to avoid GCC
9253 warnings about wrong width.
9255 2012-05-09 Eli Zaretskii <eliz@gnu.org>
9257 * w32proc.c (new_child): Force Windows to reserve only 64KB of
9258 stack for each reader_thread, instead of defaulting to 8MB
9259 determined by the linker. This avoids failures in creating
9260 subprocesses on Windows 7, see the discussion in this thread:
9261 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
9263 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
9265 Fix up display of the *Minibuf-0* buffer in the mini window.
9266 * keyboard.c (read_char): Don't clear the echo area if there's no
9268 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
9269 contents of *Minibuf-0*) if there's no message displayed in its stead.
9271 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
9273 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
9276 2012-05-06 Chong Yidong <cyd@gnu.org>
9278 * lisp.mk (lisp): Update.
9280 2012-05-05 Jim Meyering <meyering@redhat.com>
9282 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
9284 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
9286 * data.c (PUT_ERROR): New macro.
9287 (syms_of_data): Use it. Add new error type `user-error'.
9288 * undo.c (user_error): New function.
9289 (Fprimitive_undo): Use it.
9290 * print.c (print_error_message): Adjust print style for `user-error'.
9291 * keyboard.c (user_error): New function.
9292 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
9294 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
9296 Do not limit current-time-string to years 1000..9999.
9297 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
9298 (Fcurrent_time_string): Support any year that is supported by the
9299 underlying localtime representation. Don't use asctime, as it
9300 has undefined behavior for years outside the range -999..9999.
9302 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
9304 Fix race conditions involving setenv, gmtime, localtime, asctime.
9305 Without this fix, interrupts could mess up code that uses these
9306 nonreentrant functions, since setting TZ invalidates existing
9307 tm_zone or tzname values, and since most of these functions return
9308 pointers to static storage.
9309 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
9310 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
9311 Grow the critical sections to include not just invoking
9312 localtime/gmtime, but also accessing these functions' results
9313 including their tm_zone values if any, and any related TZ setting.
9314 (format_time_string): Last arg is now struct tm *, not struct tm **,
9315 so that the struct tm is saved in the critical section.
9316 All callers changed. Simplify allocation of initial buffer, partly
9317 motivated by the fact that memory allocation needs to be outside
9318 the critical section.
9320 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
9322 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
9323 with RESET_INTERVAL.
9325 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
9326 Remove duplicated buffer name initialization.
9328 2012-05-02 Jim Meyering <jim@meyering.net>
9330 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
9332 * xfns.c (x_window): Use xstrdup (Bug#11375).
9334 2012-05-02 Eli Zaretskii <eliz@gnu.org>
9336 * xdisp.c (pos_visible_p): If already at a newline from the
9337 display string before the 'while' loop, don't walk back the glyphs
9338 from it3.glyph_row. Solves assertion violation when the display
9339 string begins with a newline (egg.el). (Bug#11367)
9341 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
9343 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
9346 2012-05-01 Glenn Morris <rgm@gnu.org>
9348 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
9349 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
9350 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
9351 All were removed before 23.1.
9353 * dispnew.c: Remove HAVE_LIBNCURSES test;
9354 it is always true on relevant platforms.
9356 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
9357 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
9359 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.

9367 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
9369 Do not avoid creating empty evaporating overlays (Bug#9642).
9370 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
9371 That is, do not delete an evaporating overlay if it becomes
9372 empty after its bounds are adjusted to fit within its buffer.
9373 This fix caused other problems, and I'm reverting it until we get
9374 to the bottom of them.
9376 2012-04-27 Chong Yidong <cyd@gnu.org>
9378 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
9380 2012-04-27 Eli Zaretskii <eliz@gnu.org>
9382 * xdisp.c (pos_visible_p): If the window start position is beyond
9383 ZV, start the display from buffer beginning. Prevents assertion
9384 violation in init_iterator when the minibuffer window is scrolled
9387 * window.c (window_scroll_pixel_based): Likewise.
9389 2012-04-27 Chong Yidong <cyd@gnu.org>

9403 2012-04-26 Eli Zaretskii <eliz@gnu.org>
9405 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
9406 display element, check also the underlying string or buffer
9407 character. (Bug#11341)
9409 * w32menu.c: Include w32heap.h.
9410 (add_menu_item): If the call to AppendMenuW (via
9411 unicode_append_menu) fails, disable Unicode menus only if we are
9412 running on Windows 9X/Me.
9414 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
9416 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.

9419 2012-04-24 Martin Rudalics <rudalics@gmx.at>
9421 * keyboard.c (read_char): Don't wipe echo area for select window
9422 events: These might get delayed via `mouse-autoselect-window'

9427 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
9428 manipulation of :loaded-from data.
9430 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
9432 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
9433 now a cons (bug#11311).
9435 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
9437 Do not create empty overlays with the evaporate property (Bug#9642).
9438 * buffer.c (Fmove_overlay): Delete an evaporating overlay
9439 if it becomes empty after its bounds are adjusted to fit within
9440 its buffer. Without this fix, in a nonempty buffer (let ((o
9441 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
9442 yields an empty overlay that has the evaporate property, which is
9443 not supposed to happen.
9445 Fix minor GTK3 problems found by static checking.
9446 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)

9466 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
9467 (__malloc_size_t, __malloc_ptrdiff_t):

9480 Define using prototypes, not old style.
9481 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
9482 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.

9547 since the two debugging options are incompatible.
9548 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
9550 (mem_init, mem_insert, mem_insert_fixup):
9551 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

9560 * sysdep.c [__FreeBSD__]: Minor cleanups.
9561 (list_system_processes, system_process_attributes) [__FreeBSD__]:
9562 Use Emacs indenting style more consistently. Avoid some casts.
9563 Use 'double' consistently rather than mixing 'float' and 'double'.
9565 2012-04-21 Eduard Wiebe <usenet@pusto.de>
9567 * sysdep.c (list_system_processes, system_process_attributes):
9568 Add implementation for FreeBSD (Bug#5243).

9583 (print_object): Check for cycles even when print-circle is nil and
9584 print-gensym is t, but only check print_depth if print-circle is nil.
9586 2012-04-20 Chong Yidong <cyd@gnu.org>
9588 * process.c (wait_reading_process_output): If EIO occurs on a pty,
9589 set the status to "failed" and ensure that sentinel is run.

9644 New extern decls, to avoid calling undeclared functions.
9645 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
9646 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
9647 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.

9649 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
9650 Remove one incorrect comment and fix another.

9664 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
9665 Remove decls. This fixes an "It stinks!".
9667 * alloc.c (which_symbols): Fix alignment issue / type clash.
9669 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
9671 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

9688 Remove definition of GC_MARK_STACK, since the default now works.
9689 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
9690 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
9691 no longer the default.
9692 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
9694 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
9696 * lread.c (lisp_file_lexically_bound_p):

9717 2012-04-11 Daniel Colascione <dancol@dancol.org>
9719 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
9720 against is gone. It's better to use vfork now so that when Cygwin
9721 gains a new, working vfork, we use it automatically (bug#10398).
9723 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
9725 * window.c (save_window_save): Obey window-point-insertion-type.

9744 being loaded (bug#10424).
9746 2012-04-09 Glenn Morris <rgm@gnu.org>
9748 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
9749 not just in the obarray, before snarfing them. (Bug#11036)

9757 * process.h: Add integer `gnutls_handshakes_tried' member to
9760 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.
9761 Add convenience `GNUTLS_LOG2i' macro.
9763 * gnutls.c (gnutls_log_function2i): Convenience log function.
9764 (emacs_gnutls_read): Use new log functions,
9765 `gnutls_handshakes_tried' process member, and
9766 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
9767 attempts per process (connection).
9769 2012-04-09 Chong Yidong <cyd@gnu.org>

9775 * callint.c (Finteractive, Fcall_interactively):
9776 * minibuf.c (Fread_variable): Callers changed.
9778 2012-04-09 Eli Zaretskii <eliz@gnu.org>
9780 * xdisp.c (set_cursor_from_row): If the display string appears in
9781 the buffer at position that is closer to point than the position
9782 after the display string, display the cursor on the first glyph of
9783 the display string. Fixes cursor display when a 'display' text
9784 property immediately follows invisible text. (Bug#11094)
9786 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
9788 composite.c: use 'double' consistently
9789 * composite.c (get_composition_id): Use 'double' consistently
9790 instead of converting 'float' to 'double' and vice versa; this is
9791 easier to understand and avoids a GCC warning.
9793 2012-04-09 Glenn Morris <rgm@gnu.org>
9795 * Makefile.in: Generate leim-list with bootstrap-emacs, in
9796 preparation for dumping it with emacs. (Bug#4789)

9818 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
9819 (mark_memory): Mark Lisp_Objects only if pointers might hide in
9820 objects, as mark_maybe_pointer will catch them otherwise.
9821 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
9822 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.

9840 [!WINDOWSNT]: New macros.
9841 (init_libxml2_functions, libxml2_loaded_p): New functions.
9842 (parse_region): Call fn_xmlCheckVersion instead of using the macro

9844 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
9845 Calls xmlCleanupParser only if libxml2 was loaded (or statically
9847 (Flibxml_parse_html_region, Flibxml_parse_xml_region):

9849 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
9851 * emacs.c: Don't include libxml/parser.h.
9852 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
9853 xmlCleanupParser directly.
9855 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
9857 2012-04-07 Eli Zaretskii <eliz@gnu.org>
9859 * indent.c (Fvertical_motion): If there is a display string at
9860 point, use it.vpos to compute how many lines to backtrack after

9863 2012-04-06 Eli Zaretskii <eliz@gnu.org>
9865 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
9866 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
9867 about subtle differences between FETCH_CHAR* and STRING_CHAR*
9868 macros related to unification of CJK characters. For the details,
9869 see the discussion following the message here:
9870 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
9872 2012-04-04 Chong Yidong <cyd@gnu.org>
9874 * keyboard.c (Vdelayed_warnings_list): Doc fix.
9876 2012-04-01 Eli Zaretskii <eliz@gnu.org>

9886 2012-03-31 Eli Zaretskii <eliz@gnu.org>
9888 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
9889 position we get to after a call to move_it_to fails the
9890 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
9891 only if we wind up in a string from display property. (Bug#11063)
9893 * window.c (Fdelete_other_windows_internal): Invalidate the row
9894 and column information about mouse highlight, so that redisplay
9895 restores it after reallocating the glyph matrices. (Bug#7464)
9897 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
9898 string comes from a `display' text property, use the buffer
9899 position of that property as if we actually saw that position in
9901 (move_it_by_lines): Remove the assertion that
9902 "it->current_x == 0 && it->hpos == 0" which can be legitimately
9903 violated when there's a before-string at the beginning of a line.
9906 2012-03-30 Eli Zaretskii <eliz@gnu.org>
9908 * xdisp.c (append_space_for_newline): If the default face was
9909 remapped, use the remapped face for the appended newline.
9910 (extend_face_to_end_of_line): Use the remapped default face for
9911 extending the face to the end of the line.
9912 (display_line): Call extend_face_to_end_of_line when the default
9913 face was remapped. (Bug#11068)
9915 2012-03-29 Eli Zaretskii <eliz@gnu.org>

9935 * keyboard.c (Vselection_inhibit_update_commands): New variable.
9936 (command_loop_1): Use it; inhibit selection update for
9937 handle-select-window too (Bug#8996).
9939 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
9941 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
9943 2012-03-25 Kenichi Handa <handa@m17n.org>
9945 * dispextern.h (struct glyph): Change the bit length of
9946 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
9948 2012-03-24 Eli Zaretskii <eliz@gnu.org>
9950 * s/ms-w32.h (tzname): Include time.h before redirecting to
9951 _tzname. Fixes the MSVC build. (Bug#9960)
9953 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
9955 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
9958 * xterm.c (XTread_socket): Only modify handling_signal if
9959 !SYNC_INPUT. (Bug#11080)
9961 2012-03-23 Eli Zaretskii <eliz@gnu.org>
9963 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
9964 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
9965 when fetching a multibyte character consumes more bytes than
9966 CHAR_BYTES returns, due to unification of CJK characters in
9967 string_char. (Bug#11073)
9969 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
9971 * process.c (wait_reading_process_output): Handle pty disconnect
9972 by refraining from sending oneself a SIGCHLD (bug#10933).
9974 2012-03-22 Chong Yidong <cyd@gnu.org>

9983 2012-03-21 Chong Yidong <cyd@gnu.org>
9985 * xfaces.c (Vface_remapping_alist): Doc fix.
9987 2012-03-20 Eli Zaretskii <eliz@gnu.org>

9995 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
9996 to reflect default non-nil value of redisplay-dont-pause.
9998 2012-03-19 Kenichi Handa <handa@m17n.org>
10000 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
10001 it fit in a valid range (Bug#11003).
10003 2012-03-18 Eli Zaretskii <eliz@gnu.org>
10005 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
10006 that is not from display property, accept the row as a "cursor
10007 row" if one of the string's character has a non-nil `cursor'
10008 property. Fixes cursor positioning when there are newlines in
10009 overlay strings, e.g. in icomplete.el. (Bug#11035)
10011 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
10013 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
10015 2012-03-12 Chong Yidong <cyd@gnu.org>
10017 * eval.c (inhibit_lisp_code): Rename from
10018 inhibit_window_configuration_change_hook; move from window.c.
10020 * xfns.c (unwind_create_frame_1, Fx_create_frame):
10021 * window.c (run_window_configuration_change_hook)
10022 (syms_of_window): Callers changed.
10024 2012-03-11 Chong Yidong <cyd@gnu.org>

10042 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
10045 2012-03-03 Glenn Morris <rgm@gnu.org>
10047 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
10049 2012-03-02 Eli Zaretskii <eliz@gnu.org>
10051 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
10052 position past the first glyph_row that ends at ZV. (Bug#10902)
10053 (redisplay_window, next_element_from_string): Fix typos in
10055 (redisplay_window): Pass to move_it_vertically the margin in
10056 pixels, not in screen lines.
10058 2012-03-02 Glenn Morris <rgm@gnu.org>
10060 * buffer.c (buffer-list-update-hook): Doc fix.
10062 2012-02-29 Eli Zaretskii <eliz@gnu.org>
10064 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
10065 push_it before setting up the iterator for the first overlay
10066 string, even if we have an empty string loaded.
10067 (next_overlay_string): If there's an empty string on the iterator
10068 stack, pop the stack. (Bug#10903)
10070 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
10072 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
10073 Suggested by Stefan Monnier in
10074 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
10075 * alloc.c (widen_to_Lisp_Object): New static function.
10076 (mark_memory): Also mark Lisp_Objects by fetching pointer words
10077 and widening them to Lisp_Objects. This would work even if
10078 USE_LSB_TAG is defined and wide integers are used, which might
10079 happen in a future version of Emacs.
10081 2012-02-25 Chong Yidong <cyd@gnu.org>
10083 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
10086 * xselect.c (Fx_selection_exists_p): Doc fix.

10088 before saving to clipboard manager.
10090 2012-02-24 Chong Yidong <cyd@gnu.org>
10092 * keyboard.c (process_special_events): Handle all X selection
10093 requests in kbd_buffer, not just the next one (Bug#8869).
10095 2012-02-23 Chong Yidong <cyd@gnu.org>
10097 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
10098 call when setting menu-bar-lines and tool-bar-lines parameters.
10099 (unwind_create_frame_1): New helper function.
10101 * window.c (inhibit_window_configuration_change_hook): New var.
10102 (run_window_configuration_change_hook): Obey it.
10103 (syms_of_window): Initialize it.
10105 2012-02-22 Chong Yidong <cyd@gnu.org>

10120 when computing $valmask.
10122 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
10123 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
10124 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
10125 It's useless in that case, and it can cause problems on hosts
10126 that allocate halves of EMACS_INT values separately.
10127 Reported by Dan Horák. Diagnosed by Andreas Schwab in
10128 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
10129 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
10130 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
10131 it avoids undefined behavior on hosts where shifting right by more
10132 than the word width has undefined behavior.
10134 2012-02-19 Chong Yidong <cyd@gnu.org>
10136 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
10137 (Funhandled_file_name_directory, Ffile_name_as_directory)
10138 (Fdirectory_file_name, Fexpand_file_name)

10156 2012-02-15 Chong Yidong <cyd@gnu.org>
10158 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is

10174 2012-02-12 Chong Yidong <cyd@gnu.org>
10176 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
10177 as that creates a dangerous corner case.
10179 * window.c (Fdelete_window_internal): Invalidate the mouse
10180 highlight (Bug#9904).
10182 2012-02-12 Glenn Morris <rgm@gnu.org>

10185 (Fx_get_selection_internal, Fx_disown_selection_internal)
10186 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
10187 * nsselect.m (Fx_own_selection_internal)
10188 (Fx_disown_selection_internal, Fx_selection_exists_p)
10189 (Fx_selection_owner_p, Fx_get_selection_internal):
10190 Sync docs and argument specs with the xselect.c versions.
10192 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
10194 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.

10212 2012-02-07 Chong Yidong <cyd@gnu.org>
10214 * buffer.c (Fbuffer_local_variables)
10215 (buffer_lisp_local_variables): Handle unbound vars correctly;
10216 don't let Qunbound leak into Lisp.
10218 2012-02-07 Glenn Morris <rgm@gnu.org>
10220 * image.c (Fimagemagick_types): Doc fix.
10222 * image.c (imagemagick-render-type): Change it from a lisp object
10223 to an integer. Move the doc here from the lisp manual.

10252 * keyboard.c (adjust_point_for_property): Don't position point
10253 before BEGV. (Bug#10696)
10255 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
10257 Handle overflow when computing char display width (Bug#9496).
10258 * character.c (char_width): Return EMACS_INT, not int.
10259 (char_width, c_string_width): Check for overflow when
10260 computing the width; this is possible now that individual
10261 characters can have unbounded width. Problem introduced
10262 by merge from Emacs 23 on 2012-01-19.
10264 2012-02-02 Michael Albinus <michael.albinus@gmx.de>

10797 (ALIGN_GCTYPEBITS) [_MSC_VER]: Define.
10798 (DECL_ALIGN) [_MSC_VER]: Use it, as MSVC doesn't like bit ops in
10799 this macro definition.
10801 * s/ms-w32.h (tzname): Redirect to _tzname for all values of
10804 2011-11-27 Jan Djärv <jan.h.d@swipnet.se>

10826 * xdisp.c (redisplay_window): If cursor row is not fully visible
10827 after recentering, and scroll-conservatively is set to a large
10828 number, scroll window by a few more lines to make the cursor fully
10829 visible and out of scroll-margin. (Bug#10105)
10830 (start_display): Don't move to the next line if the display should
10831 start at a newline that is part of a display vector or an overlay
10832 string. (Bug#10119)
10834 2011-11-24 Juri Linkov <juri@jurta.org>

10912 Otherwise, valgrind does not work on some platforms.
10913 Problem reported by Andreas Schwab in
10914 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
10915 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
10916 is set, removing the need for VIRT_ADDRESS_VARIES.
10917 (PURE_P): Use a more-efficient implementation that needs just one
10918 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
10919 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
10920 to 4 (xorl, subq, cmpq, setbe).
10921 * alloc.c (pure): Always extern now, since that's the
10922 VIRT_ADDR_VARIES behavior.
10923 (PURE_POINTER_P): Use a single comparison, not two, for
10924 consistency with the new puresize.h.
10925 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
10926 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

10932 (erase_phys_cursor, update_window_cursor, show_mouse_face)
10933 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
10934 behave as if the cursor position were at the window margin.
10936 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
10937 and the cursor position is out of bounds, behave as if the cursor
10938 position were at the window margin. (Bug#10075)
10940 2011-11-18 Chong Yidong <cyd@gnu.org>
10942 * window.c (Fwindow_combination_limit): Make first argument
10943 non-optional, since it is meaningless for live windows like the

10958 hash values of the two rows.
10959 (copy_row_except_pointers): Preserve the used[] arrays and the
10960 hash values of the two rows. (Bug#10035)
10961 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
10963 * xdisp.c (row_hash): New function, body extracted from
10964 compute_line_metrics.
10965 (compute_line_metrics): Call row_hash, instead of computing the
10968 * dispnew.c (verify_row_hash): Call row_hash for computing the
10969 hash code of a row, instead of duplicating code from xdisp.c.
10971 * dispextern.h (row_hash): Add prototype.
10973 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
10975 * frame.c (delete_frame): Don't delete the terminal when the last

11000 (recombine_windows, make_parent_window, make_window)
11001 (Fsplit_window_internal, saved_window)
11002 (Fset_window_configuration, save_window_save): Rename all
11003 occurrences of window_nest to window_combination_limit.
11005 2011-11-15 Juanma Barranquero <lekktu@gmail.com>

11009 2011-11-14 Eli Zaretskii <eliz@gnu.org>
11011 * xdisp.c (display_line): Move the call to
11012 highlight_trailing_whitespace before the call to
11013 compute_line_metrics, since the latter needs to see the final
11014 faces of all the glyphs to compute ROW's hash value.
11015 Fixes assertion violations in row_equal_p. (Bug#10035)
11017 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
11019 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,
11020 just return (bug#10044).
11022 2011-11-12 Eli Zaretskii <eliz@gnu.org>
11024 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
11025 with user-defined heap size. Bump the default size of the temacs
11026 heap to 27MB, to avoid memory warning when running temacs.
11027 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
11029 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
11030 current_matrix and desired_matrix. (Bug#9990)
11031 (verify_row_hash) [XASSERTS]: New function.
11032 (adjust_glyph_matrix, row_equal_p): Use it in xassert to verify
11033 that the hash value of glyph rows is correct.

11065 avoid a crash (bug#9496).
11067 2011-11-09 Chong Yidong <cyd@gnu.org>
11069 * window.c (Fwindow_inside_edges, Fwindow_inside_pixel_edges)

11076 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
11078 Avoid some portability problems by eschewing 'extern inline' functions.
11079 The trivial performance wins aren't worth the portability hassles; see
11080 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
11082 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
11083 (window_box_width, window_box_left, window_box_left_offset)
11084 (window_box_right, window_box_right_offset): Undo previous change,
11085 by removing the "extern"s.
11086 * intervals.c (adjust_intervals_for_insertion)
11087 (adjust_intervals_for_deletion): Undo previous change,
11088 making these static again.
11089 (offset_intervals, temp_set_point_both, temp_set_point)
11090 (copy_intervals_to_string): No longer inline.
11091 * xdisp.c (window_text_bottom_y, window_box_width)

11130 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
11131 This is also needed for porting to any host where GC_MARK_STACK is
11132 not GC_MAKE_GCPROS_NOOPS.
11133 (which_symbols): Use it.
11135 2011-11-07 Kenichi Handa <handa@m17n.org>

11148 * xmenu.c (cleanup_widget_value_tree): New function.
11149 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
11150 calling free_menubar_widget_value_tree directly (Bug#9830).
11152 2011-11-06 Paul Eggert <eggert@cs.ucla.edu>
11154 Fix some portability problems with 'inline'.
11155 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
11156 (window_box_width, window_box_left, window_box_left_offset)
11157 (window_box_right, window_box_right_offset): Declare extern.
11158 Otherwise, these inline functions do not conform to C99 and
11159 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
11160 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
11161 * intervals.c (adjust_intervals_for_insertion)
11162 (adjust_intervals_for_deletion): Now extern, because otherwise the
11163 extern inline functions 'offset_intervals' couldn't refer to it.
11164 (static_offset_intervals): Remove.
11165 (offset_intervals): Rewrite using the old contents of
11166 static_offset_intervals. The old version didn't conform to C99
11167 because an extern inline function contained a reference to an
11168 identifier with static linkage.

11234 official. Move initialization of image_cache_refcount and
11235 dpyinfo_refcount before calling init_frame_faces (Bug#9943).

11280 * gtkutil.c (xg_make_tool_item): Add callbacks if one of wimage or
11281 label is not null (Bug#9951).

11303 (mouse_face_from_buffer_pos, note_mouse_highlight):
11304 Rename cover_string to disp_string.

11314 * xdisp.c (try_cursor_movement): Make sure ROW isn't decremented
11315 past the beginning of the current glyph matrix.
11317 2011-10-30 Adam Sjøgren <asjo@koldfront.dk> (tiny change)
11319 * xterm.c: Include X11/Xproto.h if HAVE_GTK3.
11320 (x_error_handler): Ignore BadMatch for X_SetInputFocus for

11363 2011-10-29 Glenn Morris <rgm@gnu.org>
11365 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
11366 Not clear what it was for, and it causes various bugs. (Bug#9839)
11368 2011-10-28 Eli Zaretskii <eliz@gnu.org>
11370 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
11371 possible random value that matches one of those tested as
11372 condition to clear the mouse face.
11374 2011-10-28 Chong Yidong <cyd@gnu.org>
11376 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.

11390 2011-10-28 Eli Zaretskii <eliz@gnu.org>
11392 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
11393 <oslsachem@gmail.com> for helping to debug this.
11395 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)

11401 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
11403 (w32font_open_internal, compute_metrics):
11404 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
11405 instead of calling the "wide" APIs directly.
11407 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
11409 * w32.h (syms_of_w32font): Add prototype.
11411 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
11413 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
11414 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
11415 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
11416 (Fmove_to_window_line): Doc fix.
11418 2011-10-27 Chong Yidong <cyd@gnu.org>
11420 * process.c (make_process): Set gnutls_state to NULL.
11422 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
11423 non-NULL, regardless of GNUTLS_INITSTAGE.
11424 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
11425 an error. Set process slots as soon as we allocate them.
11427 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
11429 2011-10-27 Chong Yidong <cyd@gnu.org>

11436 (deactivate_process): Call emacs_gnutls_deinit.
11438 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
11440 * image.c (x_create_x_image_and_pixmap):
11441 * w32.c (sys_rename, w32_delayed_load):
11442 * w32font.c (fill_in_logfont):

11448 extracted from Fw32_default_color_map.
11449 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
11451 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
11453 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
11455 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
11457 * keyboard.c (test_undefined): New function (bug#9751).
11458 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
11460 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
11462 * sysdep.c (init_sys_modes): Fix the check for the controlling
11463 terminal (Bug#6649).
11465 2011-10-20 Eli Zaretskii <eliz@gnu.org>
11467 * dispextern.h (struct bidi_it): New member next_en_type.
11469 * bidi.c (bidi_line_init): Initialize the next_en_type member.
11470 (bidi_resolve_explicit_1): When next_en_pos is valid for the
11471 current character, check also for next_en_type being WEAK_EN.
11472 (bidi_resolve_weak): Don't enter the expensive loop if the current
11473 position is before next_en_pos. Record the bidi type of the first
11474 non-ET, non-BN character we find, in addition to its position.
11475 (bidi_level_of_next_char): Invalidate next_en_type when
11476 next_en_pos is over-stepped.
11478 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
11480 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
11481 * editfns.c: Rewrite current-time-zone so that it invokes
11482 the equivalent of (format-time-string "%Z") to get the time zone name.
11483 This fixes a bug when the time zone name contains characters that
11484 need converting from the system time locale to Emacs internal format.
11485 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
11486 that patch fixed format-time-string to do the conversion, but
11487 I forgot to fix current-time-zone.
11488 (format_time_string): New function, containing most of
11489 what Fformat_time_string used to contain.
11490 (Fformat_time_string): Rewrite in terms of format_time_string.
11491 This doesn't change this function's behavior.
11492 (current-time-zone): Rewrite to use format_time_string.
11493 This fixes the bug reported by Michael Schierl in
11494 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
11495 Jason Rumney's 2007-06-07 change worked around this bug, but
11497 * systime.h (tzname, timezone): Remove no-longer-used declarations.
11499 2011-10-19 Eli Zaretskii <eliz@gnu.org>
11501 * xdisp.c (start_display): If the character at POS is displayed
11502 via a display vector, reset IT->current.dpvec_index to zero.
11503 (try_window_reusing_current_matrix): If a line ends in a display
11504 vector or the next line starts in a display vector, continue
11505 redrawing the window even though the character position of
11506 start_row was reached.
11509 2011-10-18 Chong Yidong <cyd@gnu.org>
11511 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
11512 with nobreak-char-display too.
11514 2011-10-18 Eli Zaretskii <eliz@gnu.org>
11516 Fix part 3 of bug#9771.
11517 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
11518 (bidi_resolve_neutral): Don't enter the expensive loop looking for
11519 non-neutral characters if the current character is a paragraph
11520 separator (a.k.a. Newline). This avoids running the same
11521 expensive loop twice, once when we consume the preceding newline
11522 and the other time when the line actually needs to be displayed.
11523 Avoid the loop when we see neutrals on the base embedding level
11524 following a character whose directionality is the same as the
11525 paragraph's. This avoids running the expensive loop when a line
11526 ends in a long sequence of neutrals, like control characters.
11527 Add assertion against STRONG_AL type. Slightly rearrange code
11528 that determines the type of a neutral given the first non-neutral
11530 (bidi_level_of_next_char): Set next_en_pos to zero when
11531 invalidating its info.
11533 2011-10-17 Eli Zaretskii <eliz@gnu.org>
11535 * xdisp.c (push_display_prop): Determine whether to record string
11536 or buffer position by IT->string, not by IT->method. Allow
11537 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
11538 (move_it_vertically_backward): Don't look for character position
11539 immediately after the newline when in a continuation line.
11542 2011-10-15 Martin Rudalics <rudalics@gmx.at>
11544 * window.c (coordinates_in_window): Rewrite and delabelize
11545 vertical border check. (Bug#5357) (Bug#9618)
11547 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
11549 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
11550 errors in XSetWindowBorder (bug#9310).
11552 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
11554 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
11555 avoid crash when xmalloc overrun checking is enabled.
11557 2011-10-13 Eli Zaretskii <eliz@gnu.org>
11559 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
11560 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
11561 cursor motion with <left> and <right> arrow keys.
11563 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
11564 some callers set that themselves.
11566 2011-10-12 Eli Zaretskii <eliz@gnu.org>
11568 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
11569 display string and the previous row comes from the same string and
11570 is empty. (Bug#9739) (Bug#9738)
11572 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
11574 * doc.c (get_doc_string): Encode file name (bug#9735).
11576 2011-10-12 Eli Zaretskii <eliz@gnu.org>
11578 * bidi.c (bidi_level_of_next_char):
11579 * xdisp.c (get_visually_first_element): Remove old incorrect
11580 comments regarding the Unicode Line Separator character.
11582 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
11584 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
11586 * alloc.c (Fgc_status): Do not access beyond zombies array
11587 boundary if nzombies > MAX_ZOMBIES.
11588 * alloc.c (dump_zombies): Add missing format specifier.
11590 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
11592 * xdisp.c (set_cursor_from_row): Simplify conditionals,
11593 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
11595 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
11596 Some packages use them to denote characters with modifiers.
11598 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
11600 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
11601 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
11602 matching a pp-number. Rename parameter var to var1.
11604 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
11606 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
11608 2011-10-08 Glenn Morris <rgm@gnu.org>
11610 * callint.c (Fcall_interactively): Give a more explicit error for the
11611 'c' case with a non-character input. (Bug#8479)
11613 2011-10-08 Eli Zaretskii <eliz@gnu.org>
11615 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
11617 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
11618 lines that are hscrolled on the left.
11620 * dispnew.c (buffer_posn_from_coords): Account for a possible
11621 presence of header-line. (Bug#4426)
11623 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
11625 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
11626 Don't advertise functionality which we discourage or doesn't work.
11628 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
11630 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
11631 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
11632 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
11633 this makes Emacs dump core during garbage collection on rare
11634 occasions. sizeof is obviously inferior to offsetof here, so
11635 stick with offsetof.
11636 (GC_POINTER_ALIGNMENT): New macro.
11637 (mark_memory): Omit 3rd (offset) arg; caller changed.
11638 Don't assume EMACS_INT alignment is the same as pointer alignment.
11640 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
11642 * keyboard.c (read_key_sequence_remapped): New var.
11643 (read_key_sequence): Compute remapping in the right buffer.
11644 (command_loop_1): Use read_key_sequence's remapping directly.
11646 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
11648 * dired.c (file_name_completion): Don't expand file name.
11649 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
11650 before checking file name handler.
11652 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
11653 they've been requested explicitly (bug#9591).
11655 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
11657 * keymap.c (Fsingle_key_description): Use make_specified_string
11658 instead of build_string to build string from push_key_description.
11661 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
11663 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
11664 This fixes a Y2038 bug on 64-bit hosts.
11665 * buffer.c (reset_buffer):
11666 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
11667 (Fclear_buffer_auto_save_failure):
11668 Use 0, not -1, to represent an unset failure time, since time_t
11669 might not be signed.
11671 Remove dependency on glibc malloc internals.
11672 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11673 Move back here from lisp.h, but with their new implementations.
11674 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
11675 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
11676 * charset.c (charset_table_init): New static var.
11677 (syms_of_charset): Use it instead of xmalloc. This removes a
11678 dependency on glibc malloc internals. See Eli Zaretskii's comment in
11679 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
11680 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11681 Move back to alloc.c.
11682 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
11683 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
11685 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
11687 * nsterm.m (windowDidResize): Call x_set_window_size only when
11688 ns_in_resize is true. Otherwise set pixelwidth/height and
11689 call change_frame_size (Bug#9628).
11691 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
11693 Port --enable-checking=all to Fedora 14 x86-64.
11694 * charset.c (syms_of_charset): Also account for glibc malloc's
11695 internal overhead when calculating the initial malloc maximum.
11697 Port --enable-checking=all to Fedora 14 x86.
11698 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11700 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
11701 (overrun_check_realloc, overrun_check_free):
11702 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
11703 That way, xmalloc returns a properly-aligned pointer even if
11704 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
11705 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
11706 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
11707 into account when calculating the initial malloc maximum.
11708 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11709 Move here from alloc.c, so that charset.c can use it too.
11710 Properly align; the old code wasn't right for common 32-bit hosts
11711 when configured with --enable-checking=all.
11712 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
11713 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
11715 2011-09-29 Eli Zaretskii <eliz@gnu.org>
11717 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
11720 2011-09-28 Eli Zaretskii <eliz@gnu.org>
11722 * xdisp.c (compute_display_string_end): If there's no display
11723 string at CHARPOS, return -1.
11725 * bidi.c (bidi_fetch_char): When compute_display_string_end
11726 returns a negative value, treat the character as a normal
11727 character not covered by a display string. (Bug#9624)
11729 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
11731 * lread.c (Fread_from_string): Fix typo in docstring.
11733 2011-09-27 Eli Zaretskii <eliz@gnu.org>
11735 * xdisp.c (handle_invisible_prop): If invisible text ends on a
11736 newline, reseat the iterator instead of bidi-iterating there one
11737 character at a time. (Bug#9610)
11738 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
11739 TO_CHARPOS if the bidi iterator is at base embedding level.
11741 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
11743 * lread.c (readevalloop): Use correct code for NBSP.
11744 (read1): Likewise. (Bug#9608)
11746 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
11748 * dbusbind.c (Fdbus_register_signal): When service is not
11749 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
11751 2011-09-25 Glenn Morris <rgm@gnu.org>
11753 * buffer.c (truncate-lines): Doc fix.
11755 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
11757 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
11758 (Fset_window_next_buffers): Doc fix.
11760 2011-09-24 Glenn Morris <rgm@gnu.org>
11762 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
11764 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
11766 Fix minor problems found by static checking.
11767 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
11768 * indent.c (Fvertical_motion): Fix == vs = typo.
11770 2011-09-24 Eli Zaretskii <eliz@gnu.org>
11772 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
11773 Default value is now t. Doc fix.
11775 * indent.c (Fvertical_motion): Compute and apply the overshoot
11776 logic when moving up, not only when moving down. Fix the
11777 confusing name and values of the it_overshoot_expected variable;
11778 logic changes accordingly. (Bug#9254) (Bug#9549)
11780 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
11781 CHARPOS is covered by a display string which includes newlines.
11782 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
11783 is covered by a display string with embedded newlines.
11785 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
11787 * dbusbind.c (Fdbus_register_signal): Add match rule to
11788 Vdbus_registered_objects_table. (Bug#9581)
11789 (Fdbus_register_method, Vdbus_registered_objects_table):
11792 2011-09-24 Jim Meyering <meyering@redhat.com>
11794 do not ignore write error for any output size
11795 The previous change was incomplete.
11796 While it makes emacs --batch detect the vast majority of stdout
11797 write failures, errors were still ignored whenever the output size is
11798 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
11799 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
11800 && echo FAIL: ignored write error
11801 FAIL: ignored write error
11802 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
11803 && echo FAIL: ignored write error
11804 FAIL: ignored write error
11805 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
11807 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
11809 * emacs.c (Fkill_emacs): In noninteractive mode exit
11810 non-successfully if a write error occurred on stdout. (Bug#9574)
11812 2011-09-21 Eli Zaretskii <eliz@gnu.org>
11814 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
11817 * dispextern.h (struct it): Update the comment documenting what
11820 2011-09-20 Eli Zaretskii <eliz@gnu.org>
11822 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
11823 a display string, extend search for cursor position to end of row.
11824 (find_row_edges): If the row ends in a newline from a display
11825 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
11826 Handle the case of a display string with multiple newlines.
11827 (Fcurrent_bidi_paragraph_direction): Fix search for previous
11828 non-empty line. Fixes confusing cursor motion with arrow keys at
11829 the beginning of a line that starts with whitespace.
11831 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
11833 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
11836 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
11838 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
11839 boolean (Bug#9154).
11841 2011-09-18 Eli Zaretskii <eliz@gnu.org>
11843 * xdisp.c (display_line): Record maximum and minimum buffer
11844 positions even if no glyphs were produced (e.g., by a zero-width
11845 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
11846 buffer positions that will be removed from the glyph row because
11848 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
11849 column is beyond frame width: don't subtract 1 "pixel" when
11850 computing width of the stretch.
11851 (reseat_at_next_visible_line_start): Undo the change made on
11852 2011-09-17 that saved paragraph information and restored it after
11853 the call to `reseat'. (Bug#9545)
11855 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11857 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
11858 and turn window cursor on if cleared (Bug#9415).
11860 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
11862 * search.c (boyer_moore): Take unibyte characters from pattern
11863 literally. (Bug#9458)
11865 2011-09-18 Eli Zaretskii <eliz@gnu.org>
11867 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
11869 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
11871 Fix minor problem found by static checking.
11872 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
11873 initialized, to pacify gcc -Wuninitialized.
11875 * fileio.c: Report proper errno when syscall falls.
11876 (Finsert_file_contents): Save and restore errno,
11877 so that report_file_error outputs the correct diagnostic.
11878 (Fwrite_region) [CLASH_DETECTION]: Likewise.
11880 2011-09-18 Eli Zaretskii <eliz@gnu.org>
11882 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
11884 2011-09-17 Eli Zaretskii <eliz@gnu.org>
11886 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
11887 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
11889 2011-09-17 Eli Zaretskii <eliz@gnu.org>
11891 * xdisp.c (reseat_at_next_visible_line_start): Keep information
11892 about the current paragraph and restore it after the call to reseat.
11894 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
11895 (bidi_find_paragraph_start): Search back for paragraph beginning
11896 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
11897 (bidi_move_to_visually_next): Only trigger paragraph-related
11898 computations when the last character is a newline or at EOB, not
11899 just any NEUTRAL_B. (Bug#9470)
11901 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
11902 truncated lines if point is covered by a display string. (Bug#9524)
11904 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
11906 * xselect.c: Relax test for outgoing X longs (Bug#9498).
11907 (cons_to_x_long): New function.
11908 (lisp_data_to_selection_data): Use it. Correct the test for
11909 short-versus-long data; it was negated. Break out of vector
11910 loop, for efficiency, when a long datum is discovered.
11912 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
11914 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
11916 2011-09-16 Eli Zaretskii <eliz@gnu.org>
11918 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
11919 GCC PR/17406) by declaring this function with external scope.
11921 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
11923 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
11924 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
11926 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
11928 * editfns.c (Fformat): Correctly handle text properties on "%%".

11936 * xdisp.c (get_next_display_element)
11937 (fill_composite_glyph_string): Add comments about special meaning
11938 of TAB characters in a composition.
11940 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
11942 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
11943 This occurs when processing a multibyte format.
11944 Problem reported by Wolfgang Jenker.
11946 2011-09-15 Johan Bockgård <bojohan@gnu.org>
11948 * xdisp.c (try_cursor_movement): Only check for exact match if
11949 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
11951 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
11953 Remove unused external symbols.
11954 * dispextern.h (calc_pixel_width_or_height): Remove decl.
11955 * xdisp.c (calc_pixel_width_or_height): Now static.
11956 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
11957 * indent.c (check_display_width):
11958 * w32term.c: Fix comment to match code.
11959 * xterm.c, xterm.h (x_catching_errors): Remove.
11961 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
11963 * xselect.c: Use signed conversions more consistently (Bug#9498).
11964 (selection_data_to_lisp_data): Assume incoming selection data are
11965 signed integers, not unsigned. This is to be consistent with
11966 outgoing selection data, which was modified to use signed integers
11967 in as part of the fix to Bug#9196 in response to Jan D.'s comment
11968 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
11969 expects long, not unsigned long.
11971 2011-09-14 Eli Zaretskii <eliz@gnu.org>
11973 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
11974 computation of loop end. Reported by Johan Bockgård
11977 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
11979 * frame.c (Fother_visible_frames_p): Function deleted.
11981 2011-09-12 Eli Zaretskii <eliz@gnu.org>
11983 * indent.c (compute_motion): Process display vector front to back
11984 rather than the other way around. (Bug#2496)
11986 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
11988 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
11990 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
11992 * minibuf.c (Fread_from_minibuffer): Doc fix.
11994 2011-09-11 Eli Zaretskii <eliz@gnu.org>
11996 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
11997 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
11999 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
12001 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
12002 value for non-existent files.
12004 2011-09-11 Eli Zaretskii <eliz@gnu.org>
12006 * fileio.c (Finsert_file_contents): If the file cannot be opened,
12007 set its "size" to -1. This will set the modtime_size field of
12008 the corresponding buffer to -1, which is what
12009 verify-visited-file-modtime expects for files that do not exist.
12012 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
12014 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
12016 * lisp.h: ... from here. push_key_description is no longer
12017 defined in keyboard.c, so its declaration should not be in
12018 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
12019 logically belongs with push_key_description.
12021 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
12023 * buffer.h: Include <sys/types.h> instead of <time.h>.
12024 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
12025 Problem reported by Herbert J. Skuhra.
12027 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
12029 * xml.c (parse_region): Make the parsing work for
12030 non-comment-starting XML files again (bug#9144).
12032 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
12034 * image.c (gif_load): Fix calculation of bottom and right corner.
12037 2011-09-10 Eli Zaretskii <eliz@gnu.org>
12039 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
12040 redisplay in small windows.
12042 2011-09-09 Eli Zaretskii <eliz@gnu.org>
12044 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
12046 2011-09-08 Martin Rudalics <rudalics@gmx.at>
12048 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
12049 Operate on live windows only.
12051 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
12053 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
12055 2011-09-07 Eli Zaretskii <eliz@gnu.org>
12057 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
12058 only under bidi iteration.
12060 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
12062 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
12064 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
12066 isnan: Fix porting problem to Solaris 10 with bundled gcc.
12067 Without this fix, the command to link temacs failed due to an
12068 undefined symbol __builtin_isnan. This is because
12069 /usr/include/iso/math_c99.h #defines isnan(x) to
12070 __builtin_isnan(x), but the bundled gcc, which identifies itself
12071 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
12073 * floatfns.c (isnan): #undef, and then #define to a clone of
12075 (Fisnan): Always define, since it's always available now.
12076 (syms_of_floatfns): Always define isnan at the Lisp level.
12078 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
12080 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
12082 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
12084 * fileio.c: Fix bugs with large file offsets (Bug#9428).
12085 The previous code assumed that file offsets (off_t values) fit in
12086 EMACS_INT variables, which is not true on typical 32-bit hosts.
12087 The code messed up by falsely reporting buffer overflow in cases
12088 such as (insert-file-contents "big" nil 1 2) into an empty buffer
12089 when "big" contains more than 2**29 bytes, even though this
12090 inserts just one byte and does not overflow the buffer.
12091 (Finsert_file_contents): Store file offsets as off_t
12092 values, not as EMACS_INT values. Check for overflow when
12093 converting between EMACS_INT and off_t. When checking for
12094 buffer overflow or for overlap, take the offsets into account.
12095 Don't use EMACS_INT for small values where int suffices.
12096 When checking for overlap, fix a typo: ZV was used where
12097 ZV_BYTE was intended.
12098 (Fwrite_region): Don't assume off_t fits into 'long'.
12099 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
12101 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
12103 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
12105 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
12107 sprintf-related integer and memory overflow issues (Bug#9412).
12109 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
12110 (esprintf, exprintf, evxprintf): New functions.
12111 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
12112 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
12113 (modify_event_symbol): Do not assume that the length of
12114 name_alist_or_stem is safe to alloca and fits in int.
12115 (Fexecute_extended_command): Likewise for function name and binding.
12116 (Frecursion_depth): Wrap around reliably on integer overflow.
12117 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
12118 since some callers pass EMACS_INT values.
12119 (Fsingle_key_description): Don't crash if symbol name contains more
12120 than MAX_ALLOCA bytes.
12121 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
12122 (get_minibuffer): Arg is now EMACS_INT, not int.
12123 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
12124 (esprintf, exprintf, evxprintf): New decls.
12125 * window.h (command_loop_level, minibuf_level): Reflect API changes.
12127 * dbusbind.c (signature_cat): New function.
12128 (xd_signature, Fdbus_register_signal):
12129 Do not overrun buffer; instead, report string overflow.
12131 * dispnew.c (add_window_display_history): Don't overrun buffer.
12132 Truncate instead; this is OK since it's just a log.
12134 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
12135 even if the time zone offset is outlandishly large.
12136 Don't mishandle offset == INT_MIN.
12138 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
12139 when creating daemon; the previous buffer-overflow check was incorrect.
12141 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
12142 which has the guts of the old verror function.
12144 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
12145 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
12147 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
12148 (font_unparse_xlfd): Don't blindly alloca long strings.
12149 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
12150 fits in int, when using sprintf. Use single snprintf to count
12151 length of string rather than counting it via multiple sprintfs;
12152 that's simpler and more reliable.
12153 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
12154 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
12155 sprintf, in case result does not fit in int.
12157 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
12158 (fontset_from_font): Print it.
12160 * frame.c (tty_frame_count): Now printmax_t, not int.
12161 (make_terminal_frame, set_term_frame_name): Print it.
12162 (x_report_frame_params): In X, window IDs are unsigned long,
12163 not signed long, so print them as unsigned.
12164 (validate_x_resource_name): Check for implausibly long names,
12165 and don't assume name length fits in 'int'.
12166 (x_get_resource_string): Don't blindly alloca invocation name;
12167 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
12170 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
12171 (xg_check_special_colors, xg_set_geometry):
12172 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
12174 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
12175 Use esprintf, not sprintf, in case result does not fit in int.
12177 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
12178 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
12179 it as a large positive number.
12180 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
12181 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
12183 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
12184 in case result does not fit in int.
12186 * print.c (float_to_string): Detect width overflow more reliably.
12187 (print_object): Make sprintf buffer a bit bigger, to avoid potential
12188 buffer overrun. Don't assume list length fits in 'int'. Treat
12189 print length of 0 as 0, not as infinity; to be consistent with other
12190 uses of print length in this function. Don't overflow print length
12191 index. Don't assume hash table size fits in 'long', or that
12192 vectorlike size fits in 'unsigned long'.
12194 * process.c (make_process): Use printmax_t, not int, to format
12195 process-name gensyms.
12197 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
12199 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
12200 to avoid potential buffer overrun.
12202 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
12203 if X resource line is longer than 512 bytes.
12205 * xfns.c (x_window): Make sprintf buffer a bit bigger
12206 to avoid potential buffer overrun.
12208 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
12210 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
12212 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
12214 Integer overflow fixes for scrolling, etc.
12215 Without these, Emacs silently mishandles large integers sometimes.
12216 For example, "C-u 4294967297 M-x recenter" was treated as if
12217 it were "C-u 1 M-x recenter" on a typical 64-bit host.
12219 * xdisp.c (try_window_id): Check Emacs fixnum range before
12220 converting to 'int'.
12222 * window.c (window_scroll_line_based, Frecenter):
12223 Check that an Emacs fixnum is in range before assigning it to 'int'.
12224 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
12225 values converted from Emacs fixnums.
12226 (Frecenter): Don't wrap around a line count if it is out of 'int'
12227 range; instead, treat it as an extreme value.
12228 (Fset_window_configuration, compare_window_configurations):
12229 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
12231 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
12232 that can exceed INT_MAX. Check that EMACS_INT value is in range
12233 before assigning it to the (possibly-narrower) index.
12234 (match_limit): Don't assume that a fixnum can fit in 'int'.
12236 * print.c (print_object): Use ptrdiff_t, not int, for index that can
12239 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
12240 (Fvertical_motion): Don't wrap around LINES values that don't fit
12241 in 'int'. Instead, treat them as extreme values. This is good
12242 enough for windows, which can't have more than INT_MAX lines anyway.
12244 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
12246 * Require libxml/parser.h to avoid compilation warning.
12248 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
12250 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
12251 since this reportedly can destroy thread storage.
12253 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
12255 * syntax.c (find_defun_start): Update all cache variables if
12256 exiting early (Bug#9401).
12258 2011-08-30 Eli Zaretskii <eliz@gnu.org>
12260 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
12262 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
12263 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
12264 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
12266 * term.c (tty_append_glyph): New function.
12267 (produce_stretch_glyph): Static function and its prototype deleted.
12269 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
12272 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
12274 * image.c (parse_image_spec): Check for nonnegative, not for positive,
12275 when checking :margin (Bug#9390).
12276 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
12277 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
12278 so that the name doesn't mislead. All uses changed.
12280 2011-08-28 Johan Bockgård <bojohan@gnu.org>
12282 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
12285 2011-08-27 Eli Zaretskii <eliz@gnu.org>
12287 * xdisp.c (move_it_to): Don't bail out early when reaching
12288 position beyond to_charpos, if we are scanning backwards.
12289 (move_it_vertically_backward): When DY == 0, make sure we get to
12290 the first character in the line after the newline.
12292 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
12294 * ccl.c: Improve and simplify overflow checking (Bug#9196).
12295 (ccl_driver): Do not generate an out-of-range pointer.
12296 (Fccl_execute_on_string): Remove unnecessary check for
12297 integer overflow, noted by Stefan Monnier in
12298 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
12299 Remove a FIXME that didn't need fixing.
12300 Simplify the newly-introduced buffer reallocation code.
12302 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
12304 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
12306 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
12308 Integer and memory overflow issues (Bug#9196).
12310 * doc.c (get_doc_string): Rework so that
12311 get_doc_string_buffer_size is the actual buffer size, rather than
12312 being 1 less than the actual buffer size; this makes xpalloc more
12315 * image.c (x_allocate_bitmap_record, cache_image):
12316 * xselect.c (Fx_register_dnd_atom):
12317 Simplify previous changes by using xpalloc.
12319 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
12320 since either will do and ptrdiff_t is convenient with xpalloc.
12322 * charset.c (charset_table_size)
12323 (struct charset_sort_data.priority): Now ptrdiff_t.
12324 (charset_compare): Don't overflow if priorities differ greatly.
12325 (Fsort_charsets): Don't assume list length fits in int.
12326 Check for size-calculation overflow when allocating sort data.
12327 (syms_of_charset): Allocate an initial charset table that is
12328 just under 64 KiB, to avoid problems with glibc malloc and mmap.
12330 * cmds.c (internal_self_insert): Check for size-calculation overflow.
12332 * composite.h (struct composition.glyph_len): Now int, not unsigned.
12333 The actual value is always <= INT_MAX, and leaving it unsigned made
12334 overflow checking harder.
12336 * dispextern.h (struct glyph_matrix.rows_allocated)
12337 (struct face_cache.size): Now ptrdiff_t, for convenience in use
12338 with xpalloc. The values are still always <= INT_MAX.
12340 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
12342 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
12343 (SAFE_NALLOCA): New macro.
12345 * region-cache.c (struct boundary.pos, find_cache_boundary)
12346 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
12347 (set_cache_region, invalidate_region_cache)
12348 (revalidate_region_cache, know_region_cache, region_cache_forward)
12349 (region_cache_backward, pp_cache):
12350 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
12351 so that ptrdiff_t * can be passed to xpalloc.
12352 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
12353 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
12354 (pp_cache): Don't assume cache_len fits in int.
12355 * region-cache.h: Adjust extern decls to match.
12357 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
12358 EMACS_INT, since either will do, for xpalloc.
12360 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
12361 (xnmalloc, xnrealloc, xpalloc): New functions.
12363 * bidi.c (bidi_shelve_header_size): New constant.
12364 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
12365 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
12367 * bidi.c (bidi_cache_shrink):
12368 * buffer.c (overlays_at, overlays_in, record_overlay_string)
12370 Don't update size of array until after memory allocation succeeds,
12371 because xmalloc/xrealloc may not return.
12372 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
12373 now that we have proper integer overflow checking.
12374 (record_overlay_string, overlay_strings): Catch overflows when
12375 calculating size of overlay_str_buf.
12377 * callproc.c (Fcall_process): Check for size overflow when
12378 calculating size of args2.
12379 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
12380 Normally we prefer signed values, but sticking with ptrdiff_t would
12381 require adding more-complicated checks.
12383 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
12384 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
12385 Redo buffer-overflow calculations to avoid integer overflow.
12386 Add a FIXME comment where memory seems to be over-allocated.
12388 * character.c (Fstring): Check for size-calculation overflow.
12390 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
12391 unnecessary integer overflow. Check for size overflow.
12392 (encode_coding_object): Don't update size until xmalloc succeeds.
12394 * composite.c (get_composition_id): Check for overflow in glyph
12395 length calculations.
12397 Integer and memory overflow fixes for display code.
12398 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
12399 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
12400 (scrolling_window): Check for overflow in size calculations.

12408 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
12409 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.

12412 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
12413 (get_doc_string): Check for size calculation overflow.
12414 Don't update size until allocation succeeds.
12415 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
12416 EMACS_INT, where ptrdiff_t will do.
12417 (Fsubstitute_command_keys): Check for string overflow.

12421 (message_length): Now ptrdiff_t, not int.
12422 (Fmessage_box): Don't update size until allocation succeeds.
12423 Don't assume message length fits in int.
12424 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
12426 * emacs.c (main): Do not reallocate argv, since there is a null at
12427 the end that can be overwritten, and this way there's no need to
12428 worry about size-calculation overflow.
12429 (sort_args): Check for size-calculation overflow.
12431 * eval.c (init_eval_once, grow_specpdl): Don't update size until
12433 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
12435 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
12436 (x_set_scroll_bar_width, x_figure_window_size):
12437 Check for integer overflow.
12438 (x_set_alpha): Do not assume XINT fits in int.
12440 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
12441 This is for the members text_lines, text_cols, total_lines, total_cols,
12442 where the system imposes an 'int' limit.
12444 * fringe.c (Fdefine_fringe_bitmap):
12445 Don't update size until alloc works.
12447 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
12448 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
12450 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
12451 Check for size-calculation overflow.
12452 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
12453 do, as we prefer signed integers.
12454 (id_to_widget.max_size, id_to_widget.used)
12455 (xg_store_widget_in_map, xg_remove_widget_from_map)
12456 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
12457 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
12458 Use and return ptrdiff_t, not int.
12459 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
12460 * gtkutil.h: Change prototypes to match the above.
12462 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
12463 are duplicate now that they've been promoted to lisp.h.
12464 (x_allocate_bitmap_record, x_alloc_image_color)
12465 (make_image_cache, cache_image, xpm_load):
12466 Don't update size until alloc is done.

12476 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
12477 Use ptrdiff_t, not int, to count maps.

12479 calculations. Don't update size until allocation succeeds.
12480 Redo calculations to avoid overflow.

12509 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
12510 for command line length. Do not attempt to address one before the
12511 beginning of an array, as that's not portable.
12513 * term.c (max_frame_lines): Remove; unused.
12514 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
12516 (encode_terminal_code, calculate_costs): Check for size
12517 calculation overflow.

12539 Use ptrdiff_t, not int, for sizes.
12540 (Finternal_make_lisp_face, cache_face):
12541 Check for size calculation overflow.
12542 (cache_face): Treat size calculation overflows as if they were
12543 memory exhaustion (the usual treatment), rather than aborting.
12545 * xfns.c (x_encode_text, x_set_name_internal)
12546 (Fx_change_window_property): Use ptrdiff_t, not int, to count
12547 sizes, since they can exceed INT_MAX in size. Check for size
12548 calculation overflow.
12550 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
12551 (xg_select): Check for size calculation overflow.
12552 Don't update size until alloc done.
12554 * xrdb.c (get_environ_db): Don't assume path length fits in int,
12555 as sprintf is limited to int lengths.
12557 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
12558 (X_LONG_MIN): New macros.
12559 Use them to make the following changes clearer.
12560 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
12561 This change doesn't affect the value now, but it may help remind
12562 future maintainers not to raise the value too much later.
12563 (SELECTION_QUANTUM): Remove, replacing with ...
12564 (selection_quantum): ... new function, which avoids overflow.
12566 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
12567 assumption that selection length fits in 'int'.

12571 (lisp_data_to_selection_data, clean_local_selection_data):
12572 Use ptrdiff_t, not int, to record length of selection.
12573 (x_reply_selection_request, x_get_window_property)
12574 (receive_incremental_selection, x_property_data_to_lisp):
12575 Redo calculations to avoid overflow.
12576 (x_reply_selection_request): When sending hint, ceiling it at
12577 X_LONG_MAX rather than relying on wraparound overflow to send
12579 (x_get_window_property, receive_incremental_selection)
12580 (lisp_data_to_selection_data, x_property_data_to_lisp):
12581 Check for size-calculation overflow.
12582 (x_get_window_property, receive_incremental_selection)

12584 Don't store size until memory allocation succeeds.
12585 (x_get_window_property): Plug memory leak on memory exhaustion.
12586 Don't double-block input; malloc is safe here. Don't assume 2**34
12587 - 4 fits in unsigned long. Add an xassert to check
12588 XGetWindowProperty overflow. Be more careful about overflow
12589 calculations, and distinguish size from memory overflow better.
12590 (receive_incremental_selection): When tracing, don't assume
12591 unsigned int is less than INT_MAX.
12592 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
12593 harmful) conversions of unsigned short to int.
12594 (lisp_data_to_selection_data): Don't assume that integers
12595 in the range -65535 through -1 fit in an X unsigned short.
12596 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
12597 result parameters unless successful. Rely on cons_to_unsigned
12598 to report problems with elements; the old code wasn't right anyway.
12599 (x_check_property_data): Check for int overflow; we cannot use
12600 a wider type due to X limits.
12601 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
12603 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.

12606 (x_term_init): Check for size calculation overflow.
12607 (x_color_cells): Don't store size until memory allocation succeeds.
12608 (handle_one_xevent): Use ptrdiff_t, not int, for byte counts.
12609 Don't assume alloca size is less than MAX_ALLOCA.
12610 (x_term_init): Don't assume length fits in int (sprintf is limited
12613 Use ptrdiff_t for composition IDs.
12614 * character.c (lisp_string_width):
12615 * composite.c (composition_table_size, n_compositions)
12616 (get_composition_id, composition_gstring_from_id):

12632 * image.c (xpm_get_color_table_h):
12633 * lisp.h (hash_lookup, hash_put):
12634 * minibuf.c (Ftest_completion):
12635 Use ptrdiff_t for hash table indexes, not int (which is too
12636 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
12637 32-bit --with-wide-int hosts).
12639 * charset.c (Fdefine_charset_internal): Check for integer overflow.
12640 Add a FIXME comment about memory leaks.
12641 (syms_of_charset): Don't assume xmalloc returns.

12645 * character.h (CHAR_WIDTH):
12646 * indent.c (MULTIBYTE_BYTES_WIDTH):
12647 Use sanitize_char_width to avoid undefined and/or bad behavior
12648 with outlandish widths.
12649 * character.h (sanitize_tab_width): Rename from sanitize_width,
12650 now that we have two such functions. All uses changed.
12651 (sanitize_char_width): New inline function.
12653 Don't assume that tab-width fits in int.
12654 * character.h (sanitize_width): New inline function.
12655 (SANE_TAB_WIDTH): New macro.
12656 (ASCII_CHAR_WIDTH): Use it.
12657 * indent.c (sane_tab_width): Remove. All uses replaced by

12661 * fileio.c: Integer overflow issues with file modes.
12662 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
12664 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
12665 Remove unreachable code.
12666 (read_hex, load_charset_map_from_file): Check for integer overflow.
12668 * xterm.c: Don't go over XClientMessageEvent limit.
12669 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
12670 (x_send_scroll_bar_event): Likewise. Check that the size does not
12671 exceed limits imposed by XClientMessageEvent, as well as the usual
12672 ptrdiff_t and size_t limits.
12674 * keyboard.c: Overflow, signedness and related fixes.
12675 (make_lispy_movement): Use same integer type in forward decl
12676 that is used in the definition.
12677 (read_key_sequence, keyremap_step):
12678 Change bufsize argument back to int, undoing my 2011-03-30 change.
12679 We prefer signed types, and int is wide enough here.
12680 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
12681 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
12682 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
12683 length, not size_t. Use ptrdiff_t for index, not int.
12684 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
12685 possibility of integer overflow.
12687 Overflow, signedness and related fixes for images.
12689 * dispextern.h (struct it.stack[0].u.image.image_id)

12708 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
12709 (lookup_image): Remove unnecessary tests.
12710 (xbm_image_p): Locals are now of int, not EMACS_INT,
12711 since parse_image_check makes sure they fit into int.
12712 (png_load, gif_load, svg_load_image):
12713 Prefer int to unsigned where either will do.
12714 (tiff_handler): New function, combining the cores of the
12715 old tiff_error_handler and tiff_warning_handler.
12716 This function is rewritten to use vsnprintf and thereby avoid
12717 stack buffer overflows. It uses only the features of vsnprintf
12718 that are common to both POSIX and native Microsoft.
12719 (tiff_error_handler, tiff_warning_handler): Use it.
12720 (tiff_load, gif_load, imagemagick_load_image):
12721 Don't assume :index value fits in 'int'.
12722 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
12723 (imagemagick_load_image): Check that crop parameters fit into
12724 the integer types that MagickCropImage accepts. Don't assume
12725 Vimagemagick_render_type has a nonnegative value. Don't assume
12726 size_t fits in 'long'.
12727 (gs_load): Use printmax_t to print the widest integers possible.
12728 Check for integer overflow when computing image height and width.
12730 2011-08-26 Eli Zaretskii <eliz@gnu.org>
12732 * xdisp.c (redisplay_window): Don't force window start if point
12733 will be invisible in the resulting window. (Bug#9324)

12737 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
12738 the display spec is of the form `(space ...)'.
12739 (handle_display_spec): Return the value returned by
12740 handle_single_display_spec, not just 1 or zero.
12741 (handle_single_display_spec): If the display spec is of the form
12742 `(space ...)', and specifies display in the text area, return 2
12744 (try_cursor_movement): Check for the need to scroll more
12745 accurately, and prefer exact match for point under bidi.
12746 Don't advance `row' beyond the last row of the window.
12748 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
12749 into disp_prop; all users changed.
12751 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
12752 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
12753 for the text covered by the display property.

12763 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
12764 buffers, return left-to-right.
12765 (set_cursor_from_row): Consider candidate row a win if its glyph
12766 represents a newline and point is on that newline. Fixes cursor
12767 positioning on the newline at EOL of R2L text within L2R
12768 paragraph, and vice versa.
12769 (try_cursor_movement): Check continued rows, in addition to
12770 continuation rows. Fixes unwarranted scroll when point enters a
12771 continued line of R2L text within an L2R paragraph, or vice versa.
12772 (cursor_row_p): Consider the case of point being equal to
12773 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
12774 from the end of a short line to the beginning of a continued line
12775 of R2L text within L2R paragraph.
12776 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
12777 composed characters.

12792 2011-08-22 Kenichi Handa <handa@m17n.org>
12794 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
12795 extra slot even if the purpose is char-code-property-table.
12797 2011-08-23 Eli Zaretskii <eliz@gnu.org>
12799 * xdisp.c (redisplay_window): When computing centering_position,
12800 account for the height of the header line. (Bug#8874)
12802 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
12803 instead of CHAR_TO_BYTE. Fixes a crash when a completion
12804 candidate is selected by the mouse, and that candidate has a
12805 composed character under the mouse.
12807 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
12808 coordinates reported by pos-visible-in-window-p for a composed
12809 character in column zero.
12811 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
12813 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
12815 2011-08-22 Eli Zaretskii <eliz@gnu.org>
12817 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
12818 consider it a hit if to_charpos is anywhere in the range of the
12819 composed buffer positions.
12821 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
12823 * image.c (gif_load): Don't assume that each subimage has the same
12824 dimensions as the base image. Handle disposal method that is
12825 "undefined" by the gif spec (Bug#9335).
12827 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
12829 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).
12830 (Fcondition_case): Document `debug' symbol in error handler.
12832 2011-08-19 Eli Zaretskii <eliz@gnu.org>
12834 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
12835 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
12836 from an Org mode buffer to a Speedbar frame.
12838 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
12839 a composition, take its buffer position from IT->cmp_it.charpos.
12840 Fixes cursor positioning at the beginning of a line that begins
12841 with a composed character.
12843 2011-08-18 Eli Zaretskii <eliz@gnu.org>
12845 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
12846 character bidirectional type, use STRONG_L instead. Fixes crashes
12847 in a buffer produced by `describe-categories'.
12849 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
12850 members before the level stack, so they would be saved and
12851 restored when copying iterator state. Fixes incorrect reordering
12852 around TABs covered by display properties.
12854 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
12856 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

12860 * eval.c (internal_condition_case, internal_condition_case_1)
12861 (internal_condition_case_2, internal_condition_case_n):
12862 Remove unnecessary aborts (Bug#9081).
12864 2011-08-17 Eli Zaretskii <eliz@gnu.org>
12866 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
12867 has no `load' handler, try opening the file locally. (Bug#9311)
12869 2011-08-16 Ken Brown <kbrown@cornell.edu>
12871 * gmalloc.c: Expand comment.

12875 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
12876 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.
12878 2011-08-16 Ken Brown <kbrown@cornell.edu>
12880 Fix memory allocation problems in Cygwin build (Bug#9273).
12882 * unexcw.c ( __malloc_initialized): Declare external variable.
12883 (fixup_executable): Force the dumped emacs to reinitialize malloc.
12885 * gmalloc.c [CYGWIN] (bss_sbrk_heapbase, bss_sbrk_heapinfo):
12887 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the

12915 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
12916 coordinates of the iterator when restoring from ppos_it.
12919 2011-08-14 Kenichi Handa <handa@m17n.org>
12921 * process.c (create_process): Call setup_process_coding_systems
12922 after the pid of the process is set to -1 (Bug#8162).
12924 2011-08-14 Eli Zaretskii <eliz@gnu.org>
12926 * xdisp.c (move_it_in_display_line_to): Don't invoke
12927 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
12928 ppos_it. Fixes vertical cursor motion when line beginning is
12929 covered by an image. (Bug#9296)
12931 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
12933 * nsterm.h (ns_run_ascript): Declare.

12936 * nsfns.m (as_script, as_result, as_status): New static variables.
12937 (ns_run_ascript): New function.
12938 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
12939 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
12940 the event loop. Get status from as_status (Bug#7276).
12942 * nsterm.m (sendEvent): If event is NSApplicationDefined and
12943 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
12944 the event loop (Bug#7276).
12946 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
12948 * gnutls.c (QCgnutls_bootprop_priority)

12969 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
12970 (Fnetwork_interface_list): Allocate in increments of bytes instead
12971 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
12972 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
12974 (struct ifflag_def): notrailers is smart on OSX.
12975 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
12976 Get hardware address with getifaddrs if available.
12978 2011-08-12 Eli Zaretskii <eliz@gnu.org>
12980 * xdisp.c (iterate_out_of_display_property): xassert that
12981 IT->position is set to within IT->object's boundaries. Break from
12982 the loop as soon as EOB is reached; avoids infloops in redisplay
12983 when IT->position is set up wrongly due to some bug.
12984 Set IT->current to match the bidi iterator unconditionally.
12985 (push_display_prop): Allow GET_FROM_STRING as IT->method on
12986 entry. Force push_it to save on the stack the current
12987 buffer/string position, to be restored by pop_it. Fix flags in
12988 the iterator structure wrt the object coming from a display
12989 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
12990 properties. (Bug#9284)
12992 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
12994 * fontset.c (fontset_get_font_group): Add proper type checks.

13007 no-display-properties-and-no-overlays under bidi display.
13008 Set disp_pos in the bidi iterator to avoid searches for display
13009 properties and overlays.

13017 the font entity extracted from the cache (Bug#8109).
13019 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
13021 * composite.c (autocmp_chars): Don't reset point. That is done by
13022 restore_point_unwind (Bug#5984).
13024 2011-08-07 Juri Linkov <juri@jurta.org>
13026 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
13027 to show the arg `TIME' instead of `TIMEVAL'.
13029 2011-08-06 Eli Zaretskii <eliz@gnu.org>
13031 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
13032 display property strides EOL and includes a newline, as in
13033 longlines-mode. (Bug#9254)
13034 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
13035 word-wrap under bidirectional display. (Bug#9224)
13037 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
13038 is non-zero, even if the data buffer is NULL. Fixes a crash in
13039 vertical-motion with longlines-mode. (Bug#9254)
13041 2011-08-05 Eli Zaretskii <eliz@gnu.org>
13043 * bidi.c <bidi_cache_total_alloc>: Now static.
13044 (bidi_initialize): Initialize bidi_cache_total_alloc.
13046 * xdisp.c (display_line): Release buffer allocated for shelved bidi
13049 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
13050 amount allocated this far in `bidi_cache_total_alloc'.
13051 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
13052 non-zero, only free the data buffer without restoring the cache
13053 contents. All callers changed.
13055 * dispextern.h (bidi_unshelve_cache): Update prototype.
13057 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
13058 (move_it_in_display_line, move_it_to)
13059 (move_it_vertically_backward, move_it_by_lines): Replace the call
13060 to xfree to an equivalent call to bidi_unshelve_cache.
13061 (move_it_in_display_line_to): Fix logic of returning
13062 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
13064 2011-08-05 Eli Zaretskii <eliz@gnu.org>
13066 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
13067 came from a string character with a `cursor' property. (Bug#9229)
13069 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
13071 * Makefile.in (LIB_PTHREAD): New variable.
13072 (LIBES): Add LIB_PTHREAD (Bug#9216).
13074 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
13075 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
13077 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
13079 * regex.c (re_iswctype): Remove some redundant boolean conversions.
13081 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
13083 * xterm.c (x_find_topmost_parent): New function.
13084 (x_set_frame_alpha): Find topmost parent window with
13085 x_find_topmost_parent and set the property there also (bug#9181).
13086 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
13088 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
13090 * callproc.c (Fcall_process): Avoid vfork clobbering
13091 the local vars buffer, coding_systems, current_dir.
13093 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
13095 * keymap.c (Fmake_composed_keymap): Move to subr.el.
13097 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
13099 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
13100 so that it is not optimized away.
13102 * xdisp.c (compute_display_string_pos): Remove unused local.
13104 2011-08-02 Eli Zaretskii <eliz@gnu.org>
13106 Fix slow cursor motion and scrolling in large buffers with
13107 selective display, like Org Mode buffers. (Bug#9218)
13109 * dispextern.h (struct bidi_it): New member disp_prop_p.
13111 * xdisp.c: Remove one-slot cache of display string positions.
13112 (compute_display_string_pos): Accept an additional argument
13113 DISP_PROP_P; callers changed. Scan at most 5K characters forward
13114 for a display string or property. If found, set DISP_PROP_P
13117 * bidi.c (bidi_fetch_char): Accept an additional argument
13118 DISP_PROP_P, and pass it to compute_display_string_pos.
13119 Only handle text covered by a display string if DISP_PROP_P is returned
13120 non-zero. All callers of bidi_fetch_char changed.
13122 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
13124 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
13126 2010-12-03 Don March <don@ohspite.net>
13128 * keymap.c (Fdefine_key): Fix non-prefix key error message when
13129 last character M-[char] is translated to ESC [char] (bug#7541).
13131 2011-08-02 Kenichi Handa <handa@m17n.org>
13133 * lisp.h (uniprop_table): Extern it.
13135 * chartab.c (uniprop_table): Make it non-static.
13137 2011-08-01 Eli Zaretskii <eliz@gnu.org>
13139 * xdisp.c (forward_to_next_line_start): Accept additional argument
13140 BIDI_IT_PREV, and store into it the state of the bidi iterator had
13142 (reseat_at_next_visible_line_start): Use the bidi iterator state
13143 returned by forward_to_next_line_start to restore the state of
13144 it->bidi_it after backing up to previous newline. (Bug#9212)
13146 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
13148 * regex.c (re_comp): Protoize.
13149 (re_exec): Fix return type.
13150 (regexec): Fix type of `ret'. (Bug#9203)
13152 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
13154 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
13155 This is needed if max-image-size is a floating-point number.
13157 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
13159 * print.c (print_object): Print empty symbol as ##.
13161 * lread.c (read1): Read ## as empty symbol.
13163 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
13165 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
13166 setting frame foreground color (Bug#9175).
13167 (x_set_background_color): Likewise.
13169 * nsmenu.m (-setText): Size tooltip dimensions precisely to
13170 contents (Bug#9176).
13171 (EmacsTooltip -init): Remove bezels and add shadows to
13174 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
13175 or scroll bar (Bug#8470).
13177 * nsfont.m (nsfont_open): Remove assignment to voffset and
13178 unnecessary vars hshink, expand, hd, full_height, min_height.
13179 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
13181 * nsterm.h (nsfont_info): Remove voffset field.
13183 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
13185 Implement strike-through and overline on NextStep (Bug#8863).
13187 * nsfont.m (nsfont_open): Use underline position provided by font,
13188 instead of hard-coded value of 2.
13189 (nsfont_draw): Call ns_draw_text_decoration instead.
13191 * nsterm.h: Add declaration for ns_draw_text_decoration.
13193 * nsterm.m (ns_draw_text_decoration): New function for drawing
13194 underline, overline, and strike-through.
13195 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
13196 ns_draw_text_decoration. Change treatment of cursor drawing to
13197 accommodate underlining, etc.
13199 2011-07-28 Eli Zaretskii <eliz@gnu.org>
13201 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
13204 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
13206 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
13207 Without this fix, if a signal arrives just after memory fills up,
13208 'malloc' might be invoked reentrantly.
13210 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
13211 In other words, assume that every image size is allowed, on non-X
13212 hosts. This assumption is probably wrong, but it lets Emacs compile.
13214 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
13216 * regex.c (re_iswctype): Convert return values to boolean.
13218 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
13220 * xdisp.c (compute_display_string_pos): Don't use cached display
13221 string position if the buffer had its restriction changed.
13224 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
13226 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
13228 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
13230 Integer signedness and overflow and related fixes. (Bug#9079)
13232 * bidi.c: Integer size and overflow fixes.
13233 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
13234 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
13235 (bidi_cache_find_level_change, bidi_cache_ensure_space)
13236 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
13237 (bidi_find_other_level_edge):
13238 Use ptrdiff_t instead of EMACS_INT where either will do.
13239 This works better on 32-bit hosts configured --with-wide-int.
13240 (bidi_cache_ensure_space): Check for size-calculation overflow.
13241 Use % rather than repeated addition, for better worst-case speed.
13242 Don't set bidi_cache_size until after xrealloc returns, because it
13244 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
13245 (bidi_cache_ensure_space): Also check that the bidi cache size
13246 does not exceed that of the largest Lisp string or buffer. See Eli
13247 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
13249 * alloc.c (__malloc_size_t): Remove.
13250 All uses replaced by size_t. See Andreas Schwab's note
13251 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
13253 * image.c: Improve checking for integer overflow.
13254 (check_image_size): Assume that f is nonnull, since
13255 it is always nonnull in practice. This is one less thing to
13256 worry about when checking for integer overflow later.
13257 (x_check_image_size): New function, which checks for integer
13258 overflow issues inside X.
13259 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
13260 This removes the need for a memory_full check.
13261 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
13262 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
13263 (xbm_read_bitmap_data): Change locals back to 'int', since
13264 their values must fit in 'int'.
13265 (xpm_load_image, png_load, tiff_load):
13266 Invoke x_create_x_image_and_pixmap earlier,
13267 to avoid much needless work if the image is too large.
13268 (tiff_load): Treat overly large images as if
13269 x_create_x_image_and_pixmap failed, not as malloc failures.
13270 (gs_load): Use x_check_image_size.
13272 * gtkutil.c: Omit integer casts.
13273 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
13274 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
13276 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
13278 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
13279 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
13280 would wrongly return t on a 64-bit host.
13282 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
13283 The plain *_OVERFLOW macros run afoul of GCC bug 49705
13284 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
13285 and therefore cause GCC to emit a bogus diagnostic in some cases.
13287 * image.c: Integer signedness and overflow and related fixes.
13288 This is not an exhaustive set of fixes, but it's time to
13289 record what I've got.
13290 (lookup_pixel_color, check_image_size): Remove redundant decls.
13291 (check_image_size): Don't assume that arbitrary EMACS_INT values
13292 fit in 'int', or that arbitrary 'double' values fit in 'int'.
13293 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
13294 (tiff_load, imagemagick_load_image):
13295 Check for overflow in size calculations.
13296 (x_create_x_image_and_pixmap): Remove unnecessary test for
13297 xmalloc returning NULL; that can't happen.
13298 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
13299 (xpm_color_bucket): Use better integer hashing function.
13300 (xpm_cache_color): Don't possibly over-allocate memory.
13301 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
13302 (gif_memory_source):
13303 Use ptrdiff_t, not int or size_t, to record sizes.
13304 (png_load): Don't assume values greater than 2**31 fit in 'int'.
13305 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
13306 either works, as we prefer signed integers.
13307 (tiff_read_from_memory, tiff_write_from_memory):
13308 Return tsize_t, not size_t, since that's what the TIFF API wants.
13309 (tiff_read_from_memory): Don't fail simply because the read would
13310 go past EOF; instead, return a short read.
13311 (tiff_load): Omit no-longer-needed casts.
13312 (Fimagemagick_types): Don't assume size fits into 'int'.
13314 Improve hashing quality when configured --with-wide-int.
13315 * fns.c (hash_string): New function, taken from sxhash_string.
13316 Do not discard information about ASCII character case; this
13317 discarding is no longer needed.
13318 (sxhash-string): Use it. Change sig to match it. Caller changed.
13319 * lisp.h: Declare it.
13320 * lread.c (hash_string): Remove, since we now use fns.c's version.
13321 The fns.c version returns a wider integer if --with-wide-int is
13322 specified, so this should help the quality of the hashing a bit.
13324 * emacs.c: Integer overflow minor fix.
13325 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
13326 Define only if GNU_LINUX.
13327 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
13329 * dispnew.c: Integer signedness and overflow fixes.
13330 Remove unnecessary forward decls, that were a maintenance hassle.
13331 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
13333 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
13334 (scrolling_window): Use ptrdiff_t, not int, for byte count.
13335 (prepare_desired_row, line_draw_cost):
13336 Use int, not unsigned, where either works.
13337 (save_current_matrix, restore_current_matrix):
13338 Use ptrdiff_t, not size_t, where either works.
13339 (init_display): Check for overflow more accurately, and without
13340 relying on undefined behavior.
13342 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
13343 Remove, replacing with the new symbols in lisp.h. All uses changed.
13344 * fileio.c (make_temp_name):
13345 * filelock.c (lock_file_1, lock_file):
13346 * xdisp.c (message_dolog):
13347 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
13348 Use pMd etc. instead.
13349 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
13350 replacing the pWIDE etc. symbols removed from editfns.c.
13352 * keyboard.h (num_input_events): Now uintmax_t.
13353 This is (very slightly) less likely to mess up due to wraparound.
13356 * buffer.c: Integer signedness fixes.
13357 (alloc_buffer_text, enlarge_buffer_text):
13358 Use ptrdiff_t rather than size_t when either will do, as we prefer
13361 * alloc.c: Integer signedness and overflow fixes.
13362 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
13363 (__malloc_size_t): Default to size_t, not to int.
13364 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
13365 (Fgarbage_collect, mark_object_loop_halt, mark_object):
13366 Prefer ptrdiff_t to size_t when either would do, as we prefer
13368 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
13369 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
13370 Now const. Initialize with values that are in range even if char
13372 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
13373 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
13374 These functions do the right thing with sizes > 2**32.
13375 (check_depth): Now ptrdiff_t, not int.
13376 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
13377 Adjust to new way of storing sizes. Check for size overflow bugs
13379 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
13380 slightly wrong anyway, as it missed one instance of
13381 XMALLOC_OVERRUN_CHECK_OVERHEAD.
13382 (refill_memory_reserve): Omit needless cast to size_t.
13383 (mark_object_loop_halt): Mark as externally visible.
13385 * xselect.c: Integer signedness and overflow fixes.
13386 (Fx_register_dnd_atom, x_handle_dnd_message):
13387 Use ptrdiff_t, not size_t, since we prefer signed.
13388 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
13389 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
13390 x_dnd_atoms_size and x_dnd_atoms_length.
13392 * doprnt.c: Prefer signed to unsigned when either works.
13394 * doprnt.c (doprnt):
13396 * xdisp.c (vmessage):
13397 Use ptrdiff_t, not size_t, when using or implementing doprnt,
13398 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
13399 prefer signed arithmetic to avoid comparison confusion.
13400 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
13401 but is a bit tricky.
13403 Assume freestanding C89 headers, string.h, stdlib.h.
13404 * data.c, doprnt.c, floatfns.c, print.c:
13405 Include float.h unconditionally.
13406 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
13407 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
13408 * regex.c: Likewise for stddef.h, string.h.
13409 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
13410 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
13411 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
13412 (STDC_HEADERS): Remove obsolete defines.
13413 * sysdep.c: Include limits.h unconditionally.
13415 Assume support for memcmp, memcpy, memmove, memset.
13416 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
13417 * regex.c (memcmp, memcpy):
13418 Remove; we assume C89 now.
13420 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
13421 (__malloc_safe_bcopy): Remove; no longer needed.
13423 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
13424 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
13425 well either way, and we prefer signed to unsigned.
13427 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
13429 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
13430 closes the connection while we're reading (bug#9182).
13432 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
13434 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
13435 are specified (Bug#9168).
13437 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
13439 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
13440 Found by GCC static checking and --with-wide-int on a 32-bit host.
13442 2011-07-25 Eli Zaretskii <eliz@gnu.org>
13444 * xdisp.c (compute_display_string_pos): Fix logic of caching
13445 previous display string position. Initialize cached_prev_pos to
13446 -1. Fixes slow-down at the beginning of a buffer.
13448 2011-07-24 Eli Zaretskii <eliz@gnu.org>
13450 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
13451 for attrs[LFACE_FONTSET_INDEX].
13453 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
13455 * xml.c (parse_region): Remove unused local
13456 that was recently introduced.
13458 2011-07-23 Eli Zaretskii <eliz@gnu.org>
13460 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
13461 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
13463 * xdisp.c (move_it_in_display_line_to): Record the best matching
13464 position for TO_CHARPOS while scanning the line, and restore it on
13465 exit if none of the characters scanned was an exact match.
13466 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
13467 when exact match is impossible due to invisible text, and the
13468 lines are truncated.
13470 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
13472 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
13475 2011-07-22 Eli Zaretskii <eliz@gnu.org>
13477 Fix a significant slow-down of cursor motion with C-n, C-p,
13478 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
13479 auto-repeat under bidi redisplay in fontified buffers.
13480 * xdisp.c (compute_stop_pos_backwards): New function.
13481 (next_element_from_buffer): Call compute_stop_pos_backwards to
13482 find a suitable prev_stop when we find ourselves before
13484 (reseat): Don't look for prev_stop, as that could mean a very long
13486 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
13487 <cached_disp_overlay_modiff>: Cache for last found display string
13489 (compute_display_string_pos): Return the cached position if asked
13490 about the same buffer in the same area of character positions, and
13491 the buffer wasn't changed since the time the display string
13492 position was cached.
13494 2011-07-22 Eli Zaretskii <eliz@gnu.org>
13496 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
13497 is an integer, which is important for empty lines. (Bug#9149)
13499 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
13501 * frame.c (Fmodify_frame_parameters): In tty case, update the
13502 default face if necessary (Bug#4238).
13504 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
13506 * editfns.c (Fstring_to_char): No need to explain what a character
13507 is in the docstring (Bug#6576).
13509 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
13511 * xml.c (parse_region): Make sure we always return a tree.
13513 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
13515 * xml.c (parse_region): If a document contains only comments,
13518 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
13520 * xml.c (make_dom): Return comments, too.
13522 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
13525 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
13526 and the surrounding thread.
13527 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
13528 rather than fgets, and retry after EINTR. Otherwise, 'emacs
13529 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
13531 * s/openbsd.h (BROKEN_SIGIO): Define.
13532 * unexelf.c (unexec) [__OpenBSD__]:
13533 Don't update the .mdebug section of the Alpha COFF symbol table.
13535 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
13537 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
13540 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
13542 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
13543 This fixes some race conditions on the permissions of any newly
13546 * alloc.c (valid_pointer_p): Use pipe, not open.
13547 This fixes some permissions issues when debugging.
13549 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
13550 If fchown fails to set both uid and gid, try to set just gid,
13551 as that is sometimes allowed. Adjust the file's mode to eliminate
13552 setuid or setgid bits that are inappropriate if fchown fails.
13554 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
13556 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ

13562 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
13564 * lread.c (read_integer): Unread even EOF character.
13565 (read1): Likewise. Properly record start position of symbol.
13567 * lread.c (read1): Read `#:' as empty uninterned symbol if no
13568 symbol character follows.
13570 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
13572 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
13573 This works around a problem with the previous change to Fcopy_file.
13574 Recent glibc declares fchown with __attribute__((warn_unused_result)),
13575 and without this change, GCC might complain about discarding
13576 fchown's return value.
13578 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
13580 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
13582 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
13584 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
13586 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
13588 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
13589 it's used from the C level.
13591 * process.c: Use the same condition for POLL_FOR_INPUT in both
13592 keyboard.c and process.c (bug#1858).
13594 2011-07-09 Lawrence Mitchell <wence@gmx.li>
13596 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
13597 (Fgnutls_boot): Use it.
13599 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
13601 * doc.c (Fsubstitute_command_keys): Revert last change.
13603 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
13605 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
13606 quotes the next character, and doesn't affect other longer
13607 sequences (bug#8935).
13609 * lread.c (syms_of_lread): Clarify that is isn't only
13610 `eval-buffer' and `eval-defun' that's affected by
13611 `lexical-binding' (bug#8460).
13613 2011-07-15 Eli Zaretskii <eliz@gnu.org>
13615 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
13616 bidi redisplay when a line includes both an image and is truncated.
13618 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
13620 Fix minor problems found by static checking.
13621 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
13622 (elsz): Now a signed constant, not a size_t var. We prefer signed
13623 types to unsigned, to avoid integer comparison confusion. Without
13624 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
13625 "cannot optimize loop, the loop counter may overflow", a symptom
13627 * indent.c (Fvertical_motion): Mark locals as initialized.
13628 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
13630 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
13632 * search.c (Fre_search_backward): Mention `case-fold-search' in
13633 all the re_search_* functions (bug#8138).

13653 buffer position was specified. Initialize paragraph_embedding to
13655 (reseat_to_string): Initialize the bidi iterator.
13656 (display_string): If we need to ignore text properties of
13657 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
13658 original value of -1 will not work with bidi.)
13659 (compute_display_string_pos): First arg is now struct
13660 `text_pos *'; all callers changed. Support display properties on
13662 (compute_display_string_end): Support display properties on Lisp
13664 (init_iterator, reseat_1, reseat_to_string): Initialize the
13665 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
13666 when iterating on a string not from display properties).
13667 (compute_display_string_pos, compute_display_string_end):
13668 Fix calculation of the object to scan. Fixes an error when using
13670 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
13671 base_level_stop; instead, set base_level_stop to BEGV.
13672 Fixes crashes in vertical-motion.
13673 (next_element_from_buffer): Improve commentary for when
13674 the iterator is before prev_stop.
13675 (init_iterator): Initialize bidi_p from the default value of
13676 bidi-display-reordering, not from buffer-local value. Use the
13677 buffer-local value only if initializing for buffer iteration.
13678 (handle_invisible_prop): Support invisible properties on strings
13679 that are being bidi-reordered.
13680 (set_iterator_to_next): Support bidi reordering of C strings and

13686 Use IT_STRING_CHARPOS when displaying from a Lisp string.
13687 (init_iterator): Don't initialize it->bidi_p for strings
13689 (reseat_to_string): Initialize it->bidi_p for strings here.

13697 (get_visually_first_element): New function, refactored from common
13698 parts of next_element_from_buffer, next_element_from_string, and
13699 next_element_from_c_string.
13700 (tool_bar_lines_needed, redisplay_tool_bar)
13701 (display_menu_bar): Force left-to-right direction. Add a FIXME
13702 comment for making that be controlled by a user option.
13703 (push_it, pop_it): Save and restore the state of the
13704 bidi iterator. Save and restore the bidi_p flag.

13708 (handle_single_display_spec): Set up it->bidi_it for iteration
13709 over a display string, and call bidi_init_it.

13711 (get_overlay_strings_1, push_display_prop): Set up the bidi
13712 iterator for displaying display or overlay strings.
13713 (forward_to_next_line_start): Don't use the shortcut if
13715 (back_to_previous_visible_line_start): If handle_display_prop
13716 pushed the iterator stack, restore the internal state of the bidi
13717 iterator by calling bidi_pop_it same number of times.
13718 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
13719 and we are bidi-iterating, don't decrement the iterator position;
13720 instead, set the first_elt flag in the bidi iterator, to produce
13722 (reseat_1): Remove redundant setting of string_from_display_prop_p.
13723 (push_display_prop): xassert that we are iterating a buffer.
13724 (push_it, pop_it): Save and restore paragraph_embedding member.
13725 (handle_single_display_spec, next_overlay_string)
13726 (get_overlay_strings_1, reseat_1, reseat_to_string)
13727 (push_display_prop): Set up the `unibyte' member of bidi_it.string
13728 correctly. Don't assume unibyte strings are not bidi-reordered.
13729 (compute_display_string_pos)
13730 (compute_display_string_end): Fix handling the case of C string.
13731 (push_it, pop_it): Save and restore from_disp_prop_p.

13735 (pop_it): Call iterate_out_of_display_property only if we are
13736 popping after iteration over a string that came from a display
13737 property. Fix a typo in popping stretch info. Add an assertion
13738 for verifying that the iterator position is in sync with the bidi
13740 (handle_single_display_spec, get_overlay_strings_1)
13741 (push_display_prop): Fix initialization of paragraph direction for
13742 string when that of the parent object is not yet determined.

13754 (try_scrolling, redisplay_window, display_line): Use them when
13755 saving a temporary copy of the iterator and restoring it back.
13756 (back_to_previous_visible_line_start, reseat_1)
13757 (init_iterator): Empty the bidi cache "stack".
13758 (move_it_in_display_line_to): If iterator ended up at
13759 EOL, but we never saw any buffer positions smaller than
13760 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor

13765 displayed in margins. (Bug#8133) (Bug#8867)
13766 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
13768 (pos_visible_p): Support positions in bidi-reordered lines.
13769 Save and restore bidi cache.
13771 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.
13772 (bidi_paragraph_info): Delete unused struct.

13790 Support iteration over a string.
13791 (bidi_set_sor_type, bidi_resolve_explicit_1)
13792 (bidi_resolve_explicit, bidi_type_of_next_char): ignore_bn_limit
13793 can now be zero (for strings); special values 0 and -1 were
13794 changed to -1 and -2, respectively.
13795 (bidi_char_at_pos): New function.
13796 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak):

13807 (bidi_initialize): Initialize the bidi cache start stack pointer.
13808 (bidi_cache_ensure_space): New function, refactored from part of

13824 * dispextern.h (struct bidi_string_data): New structure.
13825 (struct bidi_it): New member `string'. Make flag members be 1-bit

13827 (compute_display_string_pos, compute_display_string_end):
13829 (bidi_push_it, bidi_pop_it): Add prototypes.
13830 (struct iterator_stack_entry): New members bidi_p,
13831 paragraph_embedding, and from_disp_prop_p.
13832 (struct it): Member bidi_p is now a bit field 1 bit wide.
13833 (bidi_shelve_cache, bidi_unshelve_cache):
13834 Declare prototypes.
13836 * .gdbinit (xvectype, xvector, xcompiled, xchartable, xboolvector)

13879 Pass Qx_lost_selection_functions rather than
13880 Vx_lost_selection_functions to Frun_hook_with_args.
13882 2011-07-13 Paul Eggert <eggert@cs.ucla.edu>
13884 * buffer.c (Fget_buffer_create): Initialize inhibit_shrinking.
13885 The old code sometimes used this field without initializing it.
13887 * alloc.c (gc_sweep): Don't read past end of array.
13888 In theory, the old code could also have corrupted Emacs internals,

14194 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
14195 subseconds part to the entropy, as that's a bit more random.
14196 Prefer signed to unsigned, since the signedness doesn't matter and
14197 in general we prefer signed. When given a limit, use a
14198 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
14199 latter isn't right if USE_2_TAGS_FOR_INTS.
14200 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
14201 not 0..VALMASK. Don't discard "excess" bits that random () returns.

14213 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
14214 This is more efficient than Ffile_directory_p and avoids a minor race.

14218 * buffer.c (Foverlay_put): Say what the return value is
14221 * fileio.c (barf_or_query_if_file_exists): Check first if the file

14225 error be more correct.
14227 * fns.c (Frequire): Remove the mention of the .gz files, since

14244 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.

14344 2011-07-01 Paul Eggert <eggert@cs.ucla.edu>
14346 * eval.c (struct backtrace): Simplify and port the data structure.
14347 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
14348 signed bit field, as this assumption is not portable and it makes
14349 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
14350 "char debug_on_exit : 1" as this is not portable either; instead,
14351 use the portable "unsigned int debug_on_exit : 1". Remove unused
14352 member evalargs. Remove obsolete comments about cc bombing out.
14354 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

14422 (emacs_fixed_new): Set priv->f to argument.
14423 (emacs_fixed_get_preferred_width)
14424 (emacs_fixed_get_preferred_height): Use min_width/height from
14425 frames size_hint to set minimum and natural (Bug#8919).
14426 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
14427 and use min_width/height from frames size_hint to set
14428 min_width/height (Bug#8919).

14448 Use gnulib's dup2 module instead of rolling our own.
14449 * sysdep.c (dup2) [!HAVE_DUP2]: Remove; gnulib now does this.

14516 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
14518 Integer and buffer overflow fixes (Bug#8873).
14520 * print.c (printchar, strout): Check for string overflow.
14521 (PRINTPREPARE, printchar, strout):
14522 Don't set size unless allocation succeeds.
14524 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
14525 for sizes. Check for string overflow more accurately.
14526 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
14528 * macros.c: Integer and buffer overflow fixes.
14529 * keyboard.h (struct keyboard.kbd_macro_bufsize):
14530 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

14534 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
14536 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
14538 * lread.c: Integer overflow fixes.
14539 (read_integer): Radix is now EMACS_INT, not int,
14540 to improve quality of diagnostics for out-of-range radices.
14541 Calculate buffer size correctly for out-of-range radices.
14542 (read1): Check for integer overflow in radices, and in
14543 read-circle numbers.
14544 (read_escape): Avoid int overflow.
14545 (Fload, openp, read_buffer_size, read1)
14546 (substitute_object_recurse, read_vector, read_list, map_obarray):
14547 Use ptrdiff_t, not int, for sizes.

14562 2011-06-22 Leo Liu <sdl.web@gmail.com>
14564 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
14565 Move to minibuffer.el.
14567 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
14569 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
14570 The following patches are for when GLYPH_DEBUG && !XASSERT.
14571 * dispextern.h (trace_redisplay_p, dump_glyph_string):
14572 * dispnew.c (flush_stdout):
14573 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
14574 Mark as externally visible.
14575 * dispnew.c (check_window_matrix_pointers): Now static.
14576 * dispnew.c (window_to_frame_vpos):
14577 * xfns.c (unwind_create_frame):
14578 * xterm.c (x_check_font): Remove unused local.
14579 * scroll.c (CHECK_BOUNDS):
14580 * xfaces.c (cache_fache): Rename local to avoid shadowing.
14581 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
14582 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
14583 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
14584 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
14586 (debug_method_add): Use va_list and vsprintf rather than relying
14587 on undefined behavior with wrong number of arguments.
14588 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
14589 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
14590 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
14591 since we're not interested in debugging glyphs with old libraries.
14592 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
14593 GCC 4.6.0's static checking.
14595 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
14597 Integer overflow and signedness fixes (Bug#8873).

14613 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
14614 (.bitmaps_last, struct x_output.icon_bitmap):
14615 Use ptrdiff_t, not int, for bitmap indexes.
14616 (x_allocate_bitmap_record): Check for size overflow.
14617 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
14619 Use ptrdiff_t, not int, for overlay counts.
14620 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
14621 * editfns.c (overlays_around, get_pos_property):
14622 * textprop.c (get_char_property_and_overlay):
14623 * xdisp.c (next_overlay_change, note_mouse_highlight):
14624 * xfaces.c (face_at_buffer_position):
14625 * buffer.c (OVERLAY_COUNT_MAX): New macro.
14626 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
14627 (Fnext_overlay_change, Fprevious_overlay_change)
14628 (mouse_face_overlay_overlaps, Foverlays_in):
14629 Use ptrdiff_t, not int, for sizes.
14630 (overlays_at, overlays_in): Check for size-calculation overflow.
14632 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
14634 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
14635 (x_session_initialize): Do not assume string length fits in int.
14637 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
14638 This is unlikely, but can occur if DPI is outlandish.
14640 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
14641 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
14643 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
14644 * xrdb.c (magic_file_p, search_magic_path):
14645 Omit last arg SUFFIX; it was always 0. All callers changed.
14646 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
14648 * xfont.c (xfont_match): Avoid need for strlen.
14650 * xfns.c: Don't assume strlen fits in int.

14653 * xdisp.c (message_log_check_duplicate): Return intmax_t,
14654 not unsigned long, as we prefer signed integers. All callers changed.
14655 Detect integer overflow in repeat count.
14656 (message_dolog): Don't assume print length fits in 39 bytes.
14657 (display_mode_element): Don't assume strlen fits in int.
14659 * termcap.c: Don't assume sizes fit in int and never overflow.
14660 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
14661 (gobble_line): Check for size-calculation overflow.
14663 * minibuf.c (Fread_buffer):
14664 * lread.c (intern, intern_c_string):
14665 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
14666 Don't assume string length fits in int.

14675 Don't assume integer property fits in fixnum.
14676 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
14678 * filelock.c: Fix some buffer overrun and integer overflow issues.
14679 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
14680 Reformulate so as not to need the command string.
14681 Invoke gzip -cd rather than gunzip, as it's more portable.
14682 (lock_info_type, lock_file_1, lock_file):
14683 Don't assume pid_t and time_t fit in unsigned long.
14684 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
14685 (current_lock_owner): Prefer signed type for sizes.
14686 Use memcpy, not strncpy, where memcpy is what is really wanted.
14687 Don't assume (via atoi) that time_t and pid_t fit in int.
14688 Check for time_t and/or pid_t out of range, e.g., via a network share.
14689 Don't alloca where an auto var works fine.
14691 * fileio.c: Fix some integer overflow issues.
14692 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
14693 Don't assume string length fits in int.
14694 (directory_file_name): Don't assume string length fits in long.
14695 (make_temp_name): Don't assume pid fits in int, or that its print
14696 length is less than 20.
14698 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
14700 * coding.c (make_subsidiaries): Don't assume string length fits in int.
14702 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
14704 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
14705 We prefer signed integers, even for size calculations.
14707 * emacs.c: Don't assume string length fits in 'int'.
14708 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
14709 (main): Don't invoke strlen when not needed.

14715 (Fgetenv_internal):
14716 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
14718 * lread.c (invalid_syntax): Omit length argument.
14719 All uses changed. This doesn't fix a bug, but it simplifies the
14720 code away from its former Hollerith-constant appearance, and it's
14721 one less 'int' to worry about when looking at integer-overflow issues.
14722 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
14724 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
14725 This didn't break anything, but it didn't help either.
14726 It's confusing to put a bogus integer in a place where the actual
14727 value does not matter.
14728 (LIST_END_P): Remove unused macro and its bogus comment.
14729 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
14731 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
14732 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
14734 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
14735 We prefer signed types, and the value cannot exceed the EMACS_INT
14736 range anyway (because otherwise the length would not be representable).
14737 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
14738 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
14739 This avoids a GCC warning when WIDE_EMACS_INT.
14741 * indent.c (sane_tab_width): New function.
14742 (current_column, scan_for_column, Findent_to, position_indentation)
14743 (compute_motion): Use it. This is just for clarity.
14744 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
14746 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
14748 * lisp.h (lint_assume): New macro.
14749 * composite.c (composition_gstring_put_cache):
14750 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
14752 * editfns.c, insdel.c:
14753 Omit unnecessary forward decls, to simplify future changes.
14755 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
14757 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
14759 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
14760 Use much-faster test for byte-length change.
14761 Don't assume string byte-length fits in 'int'.
14762 Check that character arg fits in 'int'.
14763 (mapcar1): Declare byte as byte, for clarity.
14765 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
14767 * fns.c (concat): Catch string overflow earlier.
14768 Do not rely on integer wraparound.
14770 * dispextern.h (struct it.overlay_strings_charpos)
14771 (struct it.selective): Now EMACS_INT, not int.
14772 * xdisp.c (forward_to_next_line_start)
14773 (back_to_previous_visible_line_start)
14774 (reseat_at_next_visible_line_start, next_element_from_buffer):
14775 Don't arbitrarily truncate the value of 'selective' to int.
14777 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
14779 * composite.c: Don't truncate sizes to 'int'.
14780 (composition_gstring_p, composition_reseat_it)
14781 (composition_adjust_point): Use EMACS_INT, not int.
14782 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
14783 not EMACS_UINT, for indexes.
14785 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
14787 * buffer.c: Include <verify.h>.
14788 (struct sortvec.priority, struct sortstr.priority):
14789 Now EMACS_INT, not int.
14790 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
14791 (struct sortstr.size, record_overlay_string)
14792 (struct sortstrlist.size, struct sortlist.used):
14793 Don't truncate size to int.
14794 (record_overlay_string): Check for size-calculation overflow.
14795 (init_buffer_once): Check at compile-time, not run-time.
14797 2011-06-22 Jim Meyering <meyering@redhat.com>
14799 Don't leak an XBM-image-sized buffer
14800 * image.c (xbm_load): Free the image buffer after using it.
14802 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
14805 * composite.c (find_automatic_composition): Omit needless 'return 0;'
14806 that Sun C diagnosed.
14807 * fns.c (secure_hash): Fix pointer signedness issue.
14808 * intervals.c (static_offset_intervals): New function.
14809 (offset_intervals): Use it.
14811 2011-06-21 Leo Liu <sdl.web@gmail.com>
14814 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
14817 * fns.c (secure_hash): Rename from crypto_hash_function and change
14818 the first arg to accept symbols.
14819 (Fsecure_hash): New primitive.
14820 (syms_of_fns): New symbols.
14822 2011-06-20 Deniz Dogan <deniz@dogan.se>
14824 * process.c (Fset_process_buffer): Clarify return value in
14827 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
14829 * dispnew.c (add_window_display_history): Use BVAR.
14831 * xdisp.c (debug_method_add): Use BVAR.
14832 (check_window_end, dump_glyph_matrix, dump_glyph)
14833 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
14835 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
14838 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
14839 check till after the cache is created in init_frame_faces.
14841 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
14843 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
14845 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
14847 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
14848 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
14849 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
14851 Improve buffer-overflow checking (Bug#8873).
14852 * fileio.c (Finsert_file_contents):
14853 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
14854 Remove the old (too-loose) buffer overflow checks.
14855 They weren't needed, since make_gap checks for buffer overflow.
14856 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
14857 The old code merely checked for Emacs fixnum overflow, and relied
14858 on undefined (wraparound) behavior. The new code avoids undefined
14859 behavior, and also checks for ptrdiff_t and/or size_t overflow.
14861 * editfns.c (Finsert_char): Don't dump core with very negative counts.
14862 Tune. Don't use wider integers than needed. Don't use alloca.
14863 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
14865 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
14867 * insdel.c, lisp.h (buffer_overflow): New function.
14868 (insert_from_buffer_1, replace_range, replace_range_2):
14869 * insdel.c (make_gap_larger):
14870 * editfns.c (Finsert_char):
14871 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
14873 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
14875 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
14877 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
14879 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
14880 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
14882 * fileio.c: Don't assume EMACS_INT fits in off_t.
14883 (emacs_lseek): New static function.
14884 (Finsert_file_contents, Fwrite_region): Use it.
14885 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
14887 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
14889 * fns.c: Don't overflow int when computing a list length.
14890 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
14891 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
14892 truncation on 64-bit hosts. Check for QUIT every
14893 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
14894 faster and is responsive enough.
14895 (Flength): Report an error instead of overflowing an integer.
14896 (Fsafe_length): Return a float if the value is not representable
14897 as a fixnum. This shouldn't happen except in contrived situations.
14898 (Fnthcdr, Fsort): Don't assume list length fits in int.
14899 (Fcopy_sequence): Don't assume vector length fits in int.
14901 * alloc.c: Check that resized vectors' lengths fit in fixnums.
14902 (header_size, word_size): New constants.
14903 (allocate_vectorlike): Don't check size overflow here.
14904 (allocate_vector): Check it here instead, since this is the only
14905 caller of allocate_vectorlike that could cause overflow.
14906 Check that the new vector's length is representable as a fixnum.
14908 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
14909 The previous code was bogus. For example, next_almost_prime (32)
14910 returned 39, which is undesirable as it is a multiple of 3; and
14911 next_almost_prime (24) returned 25, which is a multiple of 5 so
14912 why was the code bothering to check for multiples of 7?
14914 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
14916 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
14918 Variadic C functions now count arguments with ptrdiff_t.
14919 This partly undoes my 2011-03-30 change, which replaced int with size_t.
14920 Back then I didn't know that the Emacs coding style prefers signed int.
14921 Also, in the meantime I found a few more instances where arguments
14922 were being counted with int, which may truncate counts on 64-bit
14923 machines, or EMACS_INT, which may be unnecessarily wide.
14924 * lisp.h (struct Lisp_Subr.function.aMANY)
14925 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
14926 Arg counts are now ptrdiff_t, not size_t.
14927 All variadic functions and their callers changed accordingly.
14928 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
14929 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
14930 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
14931 * callint.c (Fcall_interactively): Check arg count for overflow,
14932 to avoid potential buffer overrun. Use signed char, not 'int',
14933 for 'varies' array, so that we needn't bother to check its size
14934 calculation for overflow.
14935 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
14936 * eval.c (apply_lambda):
14937 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
14938 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
14939 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
14941 * callint.c (Fcall_interactively): Don't use index var as event count.
14943 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
14944 * mem-limits.h (SIZE): Remove; no longer used.
14946 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
14948 Remove unnecessary casts.
14949 * xterm.c (x_term_init):
14950 * xfns.c (x_set_border_pixel):
14951 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
14952 These aren't needed now that we assume ANSI C.
14954 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
14955 It's more likely to cause problems (due to unsigned overflow)
14958 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
14960 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
14962 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
14964 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
14966 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
14968 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
14970 GLYPH_CODE_FACE returns EMACS_INT, not int.
14971 * dispextern.h (merge_faces):
14972 * xfaces.c (merge_faces):
14973 * xdisp.c (get_next_display_element, next_element_from_display_vector):
14974 Don't assume EMACS_INT fits in int.
14976 * character.h (CHAR_VALID_P): Remove unused parameter.
14977 * fontset.c, lisp.h, xdisp.c: All uses changed.
14979 * editfns.c (Ftranslate_region_internal): Omit redundant test.
14981 * fns.c (concat): Minor tuning based on overflow analysis.
14982 This doesn't fix any bugs. Use int to hold character, instead
14983 of constantly refetching from Emacs object. Use XFASTINT, not
14984 XINT, for value known to be a character. Don't bother comparing
14985 a single byte to 0400, as it's always less.
14987 * floatfns.c (Fexpt):
14988 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
14990 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
14993 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
14995 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
14996 Without this fix, on a 64-bit host (aset S 0 4294967386) would
14997 incorrectly succeed when S was a string, because 4294967386 was
14998 truncated before it was used.
15000 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
15001 Otherwise, an out-of-range integer could cause undefined behavior
15004 * composite.c: Use int, not EMACS_INT, for characters.
15005 (fill_gstring_body, composition_compute_stop_pos): Use int, not
15006 EMACS_INT, for values that are known to be in character range.
15007 This doesn't fix any bugs but is the usual style inside Emacs and
15008 may generate better code on 32-bit machines.
15010 Make sure a 64-bit char is never passed to ENCODE_CHAR.
15011 This is for reasons similar to the recent CHAR_STRING fix.
15012 * charset.c (Fencode_char): Check that character arg is actually
15013 a character. Pass an int to ENCODE_CHAR.
15014 * charset.h (ENCODE_CHAR): Verify that the character argument is no
15015 wider than 'int', as a compile-time check to prevent future regressions
15018 * character.c (char_string): Remove unnecessary casts.
15020 Make sure a 64-bit char is never passed to CHAR_STRING.
15021 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
15022 by silently ignoring the top 32 bits, allowing some values
15023 that were far too large to be valid characters.
15024 * character.h: Include <verify.h>.
15025 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
15026 arguments are no wider than unsigned, as a compile-time check
15027 to prevent future regressions in this area.
15029 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
15030 (Fsubst_char_in_region):
15032 * xdisp.c (decode_mode_spec_coding):
15033 Adjust to CHAR_STRING's new requirement.
15034 * editfns.c (Finsert_char, Fsubst_char_in_region):
15035 * fns.c (concat): Check that character args are actually
15036 characters. Without this test, these functions did the wrong
15037 thing with wildly out-of-range values on 64-bit hosts.
15039 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
15040 These casts should not be needed on 32-bit hosts, either.
15041 * keyboard.c (read_char):
15042 * lread.c (Fload): Remove casts to unsigned.
15044 * lisp.h (UNSIGNED_CMP): New macro.
15045 This fixes comparison bugs on 64-bit hosts.
15046 (ASCII_CHAR_P): Use it.
15047 * casefiddle.c (casify_object):
15048 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
15049 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
15050 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
15051 * dispextern.h (FACE_FROM_ID):
15052 * keyboard.c (read_char): Use UNSIGNED_CMP.
15054 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
15055 not to EMACS_INT, to avoid GCC warning.
15057 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
15059 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
15060 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
15061 isn't needed on 32-bit machines.
15063 * buffer.c (Fgenerate_new_buffer_name):
15064 Use EMACS_INT for count, not int.
15065 (advance_to_char_boundary): Return EMACS_INT, not int.
15067 * data.c (Qcompiled_function): Now static.
15069 * window.c (window_body_lines): Now static.
15071 * image.c (gif_load): Rename local to avoid shadowing.
15073 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
15074 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
15075 * alloc.c (make_save_value): Integer argument is now of type
15076 ptrdiff_t, not int.
15077 (mark_object): Use ptrdiff_t, not int.
15078 * lisp.h (pD): New macro.
15079 * print.c (print_object): Use it.
15081 * alloc.c: Use EMACS_INT, not int, to count objects.
15082 (total_conses, total_markers, total_symbols, total_vector_size)
15083 (total_free_conses, total_free_markers, total_free_symbols)
15084 (total_free_floats, total_floats, total_free_intervals)
15085 (total_intervals, total_strings, total_free_strings):
15086 Now EMACS_INT, not int. All uses changed.
15087 (Fgarbage_collect): Compute overall total using a double, so that
15088 integer overflow is less likely to be a problem. Check for overflow
15089 when converting back to an integer.
15090 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
15091 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
15092 These were 'int' variables that could overflow on 64-bit hosts;
15093 they were never used, so remove them instead of repairing them.
15094 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
15095 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
15096 Previously, this ceilinged at INT_MAX, but that doesn't work on
15098 (allocate_pseudovector): Don't use EMACS_INT when int would do.
15100 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
15101 (allocate_vectorlike): Check for ptrdiff_t overflow.
15102 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
15103 when a (possibly-narrower) signed value would do just as well.
15104 We prefer using signed arithmetic, to avoid comparison confusion.
15106 * alloc.c: Catch some string size overflows that we were missing.
15107 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
15108 for convenience in STRING_BYTES_MAX.
15109 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
15110 The definition here is exact; the one in lisp.h was approximate.
15111 (allocate_string_data): Check for string overflow. This catches
15112 some instances we weren't catching before. Also, it catches
15113 size_t overflow on (unusual) hosts where SIZE_MAX <= min
15114 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
15115 and ptrdiff_t and EMACS_INT are both 64 bits.
15117 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
15118 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
15119 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
15121 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
15123 * alloc.c (Fmake_string): Check for out-of-range init.
15125 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
15127 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
15129 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
15131 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
15132 xg_get_default_scrollbar_width.
15134 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
15135 (int_gtk_range_get_value): Move to the scroll bar part of the file.
15136 (style_changed_cb): Call update_theme_scrollbar_width and call
15137 x_set_scroll_bar_default_width and xg_frame_set_char_size for
15138 all frames (Bug#8505).
15139 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
15140 Call gtk_window_set_resizable if HAVE_GTK3.
15141 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
15142 and height if HAVE_GTK3 (Bug#8505).
15143 (scroll_bar_width_for_theme): New variable.
15144 (update_theme_scrollbar_width): New function.
15145 (xg_get_default_scrollbar_width): Move code to
15146 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
15147 (xg_initialize): Call update_theme_scrollbar_width.
15149 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
15151 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
15153 2011-06-12 Martin Rudalics <rudalics@gmx.at>
15155 * frame.c (make_frame): Call other_buffer_safely instead of
15158 * window.c (temp_output_buffer_show): Call display_buffer with
15159 second argument Vtemp_buffer_show_specifiers and reset latter
15160 immediately after the call.
15161 (Vtemp_buffer_show_specifiers): New variable.
15162 (auto_window_vscroll_p, next_screen_context_lines)
15163 (Vscroll_preserve_screen_position): Remove leading asterisks from
15166 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
15168 Fix minor problems found by GCC 4.6.0 static checking.
15169 * buffer.c (Qclone_number): Remove for now, as it's unused.
15170 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
15171 (record_buffer): Remove unused local.
15172 * frame.c (other_visible_frames, frame_buffer_list): Now static.
15173 (set_frame_buffer_list): Remove; unused.
15174 * frame.h (other_visible_frames): Remove decl.
15175 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
15176 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
15177 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
15179 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
15180 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
15181 Define only if HAVE_GPM.
15182 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
15183 (update_hints_inhibit): Remove; never set. All uses removed.
15184 * widgetprv.h (emacsFrameClassRec): Remove decl.
15185 * window.c (delete_deletable_window): Now returns void, since it
15186 wasn't returning anything.
15187 (compare_window_configurations): Remove unused locals.
15188 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
15189 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
15190 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
15191 the same widths as pointers. This follows up on the 2011-05-06 patch.
15192 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
15193 * xterm.h: Likewise.
15194 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.
15196 2011-06-12 Juanma Barranquero <lekktu@gmail.com>
15198 * makefile.w32-in: Update dependencies.
15199 (LISP_H): Add lib/intprops.h.
15201 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
15203 * image.c (gif_load): Add animation frame delay to the metadata.
15204 (syms_of_image): Use DEFSYM. New symbol `delay'.
15206 2011-06-11 Martin Rudalics <rudalics@gmx.at>
15208 * window.c (delete_deletable_window): Re-add.

15662 (x_get_foreign_selection): Reduce scope of x_catch_errors (Bug#8790).
15664 2011-06-04 Dan Nicolaescu <dann@ics.uci.edu>
15666 * emacs.c (main): Warn when starting a GTK emacs in daemon mode.
15668 2011-06-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15670 * fringe.c (update_window_fringes): Don't update overlay arrow bitmap
15671 in the current matrix if keep_current_p is non-zero.
15673 2011-06-04 Eli Zaretskii <eliz@gnu.org>
15675 * bidi.c (bidi_level_of_next_char): Fix last change.
15677 2011-06-03 Eli Zaretskii <eliz@gnu.org>
15679 Support bidi reordering of text covered by display properties.
15681 * bidi.c (bidi_copy_it): Use offsetof instead of emulating it.
15682 (bidi_fetch_char, bidi_fetch_char_advance): New functions.
15683 (bidi_cache_search, bidi_cache_iterator_state)
15684 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
15685 (bidi_level_of_next_char, bidi_move_to_visually_next):
15686 Support character positions inside a run of characters covered by a
15688 (bidi_paragraph_init, bidi_resolve_explicit_1)
15689 (bidi_level_of_next_char): Call bidi_fetch_char and
15690 bidi_fetch_char_advance instead of FETCH_CHAR and
15691 FETCH_CHAR_ADVANCE.
15692 (bidi_init_it): Initialize new members.
15693 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
15695 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
15696 instead of using explicit *_CHAR codes.
15697 (bidi_resolve_explicit, bidi_resolve_weak):
15698 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
15699 bidirectional text is supported only in multibyte buffers.
15700 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
15701 it to initialize the frame_window_p member of struct bidi_it.
15702 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
15703 (bidi_resolve_explicit, bidi_resolve_weak)
15704 (bidi_level_of_next_char, bidi_move_to_visually_next): Abort if
15705 bidi_it->nchars is non-positive.
15706 (bidi_level_of_next_char): Don't try to lookup the cache for the
15707 next/previous character if nothing is cached there yet, or if we
15708 were just reseat()'ed to a new position.
15710 * xdisp.c (set_cursor_from_row): Set start and stop points
15711 according to the row's direction when priming the loop that looks
15712 for the glyph on which to display cursor.
15713 (single_display_spec_intangible_p): Function deleted.
15714 (display_prop_intangible_p): Reimplement to call
15715 handle_display_spec instead of single_display_spec_intangible_p.
15716 Accept 3 additional arguments needed by handle_display_spec.
15717 This fixes incorrect cursor motion across display property with complex
15718 values: lists, `(when COND...)' forms, etc.
15719 (single_display_spec_string_p): Support property values that are
15720 lists with the argument STRING its top-level element.
15721 (display_prop_string_p): Fix the condition for processing a
15722 property that is a list to be consistent with handle_display_spec.
15723 (handle_display_spec): New function, refactored from the
15724 last portion of handle_display_prop.
15725 (compute_display_string_pos): Accept additional argument
15726 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
15727 value of a `display' property is a "replacing spec".
15728 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
15729 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
15730 the display property, but just return a value indicating whether
15731 the display property will replace the characters it covers.
15732 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
15733 frame_window_p members of struct bidi_it.
15734 (compute_display_string_pos, compute_display_string_end):
15736 (push_it): Accept second argument POSITION, where pop_it should
15737 jump to continue iteration.
15738 (reseat_1): Initialize bidi_it.disp_pos.
15740 * keyboard.c (adjust_point_for_property): Adjust the call to
15741 display_prop_intangible_p to its new signature.
15743 * dispextern.h (struct bidi_it): New member frame_window_p.
15744 (bidi_init_it): Update prototypes.
15745 (display_prop_intangible_p): Update prototype.
15746 (compute_display_string_pos, compute_display_string_end):
15747 Declare prototypes.
15748 (struct bidi_it): New members nchars and disp_pos. ch_len is now
15751 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
15753 Malloc failure behavior now depends on size of allocation.
15754 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
15755 * lisp.h: Change signatures accordingly.
15756 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
15757 All callers changed. (Bug#8762)
15759 * gnutls.c: Use Emacs's memory allocators.
15760 Without this change, the gnutls library would invoke malloc etc.
15761 directly, which causes problems on non-SYNC_INPUT hosts, and which
15762 runs afoul of improving memory_full behavior. (Bug#8761)
15763 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
15764 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
15765 xfree instead of the default malloc, realloc, free.
15766 (Fgnutls_boot): No need to check for memory allocation failure,
15767 since xmalloc does that for us.
15769 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
15770 * category.c (hash_get_category_set):
15771 * ccl.c (ccl_driver):
15772 * charset.c (Fdefine_charset_internal):
15773 * charset.h (struct charset.hash_index):

15783 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
15784 (Fsxhash, Fgethash, Fputhash, Fmaphash):
15785 * image.c (make_image, search_image_cache, lookup_image)
15786 (xpm_put_color_table_h):
15787 * lisp.h (struct Lisp_Hash_Table):
15788 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
15789 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
15790 for hashes and hash indexes, instead of 'unsigned' and 'int'.
15791 * alloc.c (allocate_vectorlike):
15792 Check for overflow in vector size calculations.
15793 * ccl.c (ccl_driver):
15794 Check for overflow when converting EMACS_INT to int.
15795 * fns.c, image.c: Remove unnecessary static decls that would otherwise
15796 need to be updated by these changes.
15797 * fns.c (make_hash_table, maybe_resize_hash_table):
15798 Check for integer overflow with large hash tables.
15799 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
15800 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
15801 (SXHASH_REDUCE): New macro.
15802 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
15803 Use it instead of discarding useful hash info with large hash values.
15804 (sxhash_float): New function.
15805 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
15806 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
15807 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
15808 Rewrite to use FIXNUM_BITS, as this simplifies things.
15809 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
15810 Adjust signatures to match updated version of code.
15811 (consing_since_gc): Now EMACS_INT, since a single hash table can
15812 use more than INT_MAX bytes.
15814 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
15816 Make it possible to build with GCC-4.6+ -O2 -flto.
15818 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
15820 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
15822 * minibuf.c (get_minibuffer, read_minibuf_unwind):
15823 Call minibuffer-inactive-mode.
15825 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
15827 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
15828 Update dependencies.
15830 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
15832 * data.c (init_data): Remove code for UTS, this system is not
15835 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
15837 Don't force ./temacs to start in terminal mode.
15839 * frame.c (make_initial_frame): Initialize faces in all cases, not
15840 only when CANNOT_DUMP is defined.
15841 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
15843 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
15845 * dispnew.c (add_window_display_history): Use const for the string
15846 pointer. Remove declaration, not needed.
15848 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
15850 Use 'inline', not 'INLINE'.
15851 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
15852 * alloc.c, fontset.c (INLINE): Remove.
15853 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
15854 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
15855 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
15856 * gmalloc.c (register_heapinfo): Use inline unconditionally.
15857 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
15859 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
15861 Make it possible to run ./temacs.
15863 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
15864 syms_of_callproc does the same thing. Remove test for
15865 "initialized", do it in the caller.
15866 * emacs.c (main): Avoid calling set_initial_environment when dumping.
15868 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
15870 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
15871 (read_minibuf): Use get_minibuffer.
15872 (syms_of_minibuf): Use DEFSYM.
15873 (Qmetadata): New var.
15874 * data.c (Qbuffer): Don't make it static.
15875 (syms_of_data): Use DEFSYM.
15877 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
15879 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
15880 (CCL_CODE_MIN): New macro.
15882 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
15884 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
15886 * eval.c (Qdebug): Now static.
15887 * lisp.h (Qdebug): Remove decl. This reverts a part of the
15888 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
15889 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
15891 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
15893 * image.c: Various fixes to ImageMagick code comments.
15894 (Fimagemagick_types): Doc fix.
15896 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
15898 Minor fixes prompted by GCC 4.6.0 warnings.
15900 * xselect.c (converted_selections, conversion_fail_tag): Now static.
15902 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
15903 (x_clipboard_manager_save_all): Move extern decl to ...
15904 * xterm.h: ... here, so that it can be checked for consistency.
15906 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
15908 * xselect.c (x_clipboard_manager_save_frame)
15909 (x_clipboard_manager_save_all): New functions.
15910 (Fx_clipboard_manager_save): Lisp function deleted.
15912 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
15913 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
15915 * xterm.h: Update prototype.
15917 2011-05-28 William Xu <william.xwl@gmail.com>
15919 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
15920 exiting (Bug#8239).
15922 2011-05-28 Jim Meyering <meyering@redhat.com>
15924 Avoid a sign-extension bug in crypto_hash_function.
15925 * fns.c (to_uchar): Define.
15926 (crypto_hash_function): Use it to convert some newly-signed
15927 variables to unsigned, to avoid sign-extension bugs. For example,
15928 without this change, (md5 "truc") would evaluate to
15929 45723a2aff78ff4fff7fff1114760e62 rather than the expected
15930 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
15931 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
15933 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
15935 Integer overflow fixes.
15937 * dbusbind.c: Serial number integer overflow fixes.
15938 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
15939 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
15940 to hold a serial number that is too large for a fixnum.
15941 (Fdbus_method_return_internal, Fdbus_method_error_internal):
15942 Check for serial numbers out of range. Decode any serial number
15943 that was so large that it became a float. (Bug#8722)
15945 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
15946 (Fdbus_call_method, Fdbus_call_method_asynchronously):
15947 Use XFASTINT rather than XUINT when numbers are nonnegative.
15948 (xd_append_arg, Fdbus_method_return_internal):
15949 (Fdbus_method_error_internal): Likewise. Also, for unsigned
15950 arguments, check that Lisp number is nonnegative, rather than
15951 silently wrapping negative numbers around. (Bug#8722)
15952 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
15955 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
15957 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
15959 ccl: Add integer overflow checks.
15960 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
15961 (IN_INT_RANGE): New macros.
15962 (ccl_driver): Use them to check for integer overflow when
15963 decoding a CCL program. Many of the new checks are whether XINT (x)
15964 fits in int; it doesn't always, on 64-bit hosts. The new version
15965 doesn't catch all possible integer overflows, but it's an
15966 improvement. (Bug#8719)
15968 * alloc.c (make_event_array): Use XINT, not XUINT.
15969 There's no need for unsigned here.
15971 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
15972 This follows up to the 2011-05-06 change that substituted uintptr_t
15973 for EMACS_INT. This case wasn't caught back then.
15975 Rework Fformat to avoid integer overflow issues.
15976 * editfns.c: Include <float.h> unconditionally, as it's everywhere
15977 now (part of C89). Include <verify.h>.
15978 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
15979 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
15980 (Fformat): Avoid the prepass trying to compute sizes; it was only
15981 approximate and thus did not catch overflow reliably. Instead, walk
15982 through the format just once, formatting and computing sizes as we go,
15983 checking for integer overflow at every step, and allocating a larger
15984 buffer as needed. Keep track separately whether the format is
15985 multibyte. Keep only the most-recently calculated precision, rather
15986 than them all. Record whether each argument has been converted to
15987 string. Use EMACS_INT, not int, for byte and char and arg counts.
15988 Support field widths and precisions larger than INT_MAX. Avoid
15989 sprintf's undefined behavior with conversion specifications such as %#d
15990 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
15991 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
15992 formatting out-of-range floating point numbers with int
15993 formats. (Bug#8668)
15995 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
15997 * data.c: Avoid integer truncation in expressions involving floats.
15998 * data.c: Include <intprops.h>.
15999 (arith_driver): When there's an integer overflow in an expression
16000 involving floating point, convert the integers to floating point
16001 so that the resulting value does not suffer from catastrophic
16002 integer truncation. For example, on a 64-bit host (* 4
16003 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
16004 Do not rely on undefined behavior after integer overflow.
16006 merge count_size_as_multibyte, parse_str_to_multibyte
16007 * character.c, character.h (count_size_as_multibyte):
16008 Rename from parse_str_to_multibyte; all uses changed.
16009 Check for integer overflow.
16010 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
16011 since it's now a duplicate of the other. This is more of
16012 a character than a buffer op, so better that it's in character.c.
16013 * fns.c, print.c: Adjust to above changes.
16015 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
16017 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
16019 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
16021 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
16022 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
16023 (x_clipboard_manager_save): Now static.
16024 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
16026 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
16027 (crypto_hash_function): Now static.
16028 Fix pointer signedness problems. Avoid unnecessary initializations.
16030 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
16032 * termhooks.h (Vselection_alist): Make it terminal-local.
16034 * terminal.c (create_terminal): Initialize it.
16036 * xselect.c: Support for clipboard managers.
16037 (Vselection_alist): Move to termhooks.h as terminal-local var.
16038 (LOCAL_SELECTION): New macro.
16039 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
16040 (symbol_to_x_atom): Remove gratuitous arg.
16041 (x_handle_selection_request, lisp_data_to_selection_data)
16042 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
16043 (x_own_selection, x_get_local_selection, x_convert_selection):
16044 New arg, specifying work frame. Use terminal-local Vselection_alist.
16045 (some_frame_on_display): Delete unused function.
16046 (Fx_own_selection_internal, Fx_get_selection_internal)
16047 (Fx_disown_selection_internal, Fx_selection_owner_p)
16048 (Fx_selection_exists_p): New optional frame arg.
16049 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
16050 (x_handle_selection_clear): Don't treat other terminals with the
16051 same keyboard specially. Use the terminal-local Vselection_alist.
16052 (x_clear_frame_selections): Use Frun_hook_with_args.
16054 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
16056 * xterm.h: Add support for those atoms.
16058 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
16060 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
16061 (converted_selections, conversion_fail_tag): New global variables.
16062 (x_selection_request_lisp_error): Free the above.
16063 (x_get_local_selection): Remove unnecessary code.
16064 (x_reply_selection_request): Args changed; handle arbitrary array
16065 of converted selections stored in converted_selections.
16066 Separate the XChangeProperty and SelectionNotify steps.
16067 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
16068 (x_convert_selection): New function.
16069 (x_handle_selection_event): Simplify.
16070 (x_get_foreign_selection): Don't ignore incoming requests while
16071 waiting for an answer; this will fail when we implement
16072 SAVE_TARGETS, and seems unnecessary anyway.
16073 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
16074 (Vx_sent_selection_functions): Doc fix.
16076 2011-05-26 Leo Liu <sdl.web@gmail.com>
16078 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
16080 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16082 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
16084 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
16085 for fringe update if it has periodic bitmap.
16086 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
16087 and fringe_bitmap_periodic_p.
16089 * fringe.c (get_fringe_bitmap_data): New function.
16090 (draw_fringe_bitmap_1, update_window_fringes): Use it.
16091 (update_window_fringes): Record periodicity of fringe bitmap in glyph
16092 row. Mark glyph row for fringe update if periodicity changed.
16094 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
16095 for fringe update unless it has periodic bitmap.
16097 2011-05-25 Kenichi Handa <handa@m17n.org>
16099 * xdisp.c (get_next_display_element): Set correct it->face_id for
16100 a static composition.
16102 2011-05-24 Leo Liu <sdl.web@gmail.com>
16105 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
16107 * fns.c (crypto_hash_function, Fsha1): New function.
16108 (Fmd5): Use crypto_hash_function.
16109 (syms_of_fns): Add Ssha1.
16111 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
16113 * gnutls.c: Remove unused macros.
16114 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
16115 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
16116 Remove macros that are defined and never used.
16117 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
16119 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
16121 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
16122 (Fx_get_selection_internal): Minor cleanup.
16123 (Fx_own_selection_internal): Rename arguments for consistency with
16126 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
16128 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
16130 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
16132 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
16134 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16136 * dispnew.c (scrolling_window): Don't exclude the case that the
16137 last enabled row in the desired matrix touches the bottom boundary.
16139 2011-05-21 Glenn Morris <rgm@gnu.org>
16141 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
16142 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
16143 and add some more files.
16145 2011-05-20 Eli Zaretskii <eliz@gnu.org>
16147 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
16148 report_file_error introduced by the change from 2011-05-07.
16150 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
16152 * systime.h (Time): Define only if emacs is defined.
16153 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
16154 where the include path doesn't have X11/X.h by default. See
16155 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
16157 2011-05-20 Kenichi Handa <handa@m17n.org>
16159 * composite.c (find_automatic_composition): Fix previous change.
16161 2011-05-20 Glenn Morris <rgm@gnu.org>
16163 * lisp.mk: New file, split from Makefile.in.
16164 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
16165 (shortlisp): Remove.
16166 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
16168 2011-05-19 Glenn Morris <rgm@gnu.org>
16170 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
16171 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
16172 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
16173 (lisp): Set the order to that of loadup.el.
16174 (shortlisp): Make it a copy of $lisp.
16175 (SOME_MACHINE_LISP): Remove.
16176 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
16177 Use just $shortlisp, not $SOME_MACHINE_LISP too.
16179 2011-05-18 Kenichi Handa <handa@m17n.org>
16181 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
16182 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
16183 (find_automatic_composition): Mostly rewrite for efficiency.
16185 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
16187 * makefile.w32-in: Update dependencies.
16189 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
16191 * menu.c: Include limits.h (fixes the MS-Windows build broken by
16192 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
16194 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
16196 Fix some integer overflow issues, such as string length overflow.
16198 * insdel.c (count_size_as_multibyte): Check for string overflow.
16200 * character.c (lisp_string_width): Check for string overflow.
16201 Use EMACS_INT, not int, for string indexes and lengths; in
16202 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
16203 the resulting string length overflows an EMACS_INT; instead,
16204 report a string overflow if no precision given. When checking for
16205 precision exhaustion, use a check that cannot possibly have
16206 integer overflow. (Bug#8675)
16207 * character.h (lisp_string_width): Adjust to new signature.
16209 * alloc.c (string_overflow): New function.
16210 (Fmake_string): Use it. This doesn't change behavior, but saves
16211 a few bytes and will simplify future changes.
16212 * character.c (string_escape_byte8): Likewise.
16213 * lisp.h (string_overflow): New decl.
16215 Fixups, following up to the user-interface timestamp change.
16216 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
16217 for UI timestamps, instead of unsigned long.
16218 * msdos.c (mouse_get_pos): Likewise.
16219 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
16220 * w32gui.h (Time): Define by including "systime.h" rather than by
16221 declaring it ourselves. (Bug#8664)
16223 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
16224 * image.c (clear_image_cache): Likewise.
16226 * term.c (term_mouse_position): Don't assume time_t wraparound.
16228 Be more systematic about user-interface timestamps.
16229 Before, the code sometimes used 'Time', sometimes 'unsigned long',
16230 and sometimes 'EMACS_UINT', to represent these timestamps.
16231 This change causes it to use 'Time' uniformly, as that's what X uses.
16232 This makes the code easier to follow, and makes it easier to catch
16233 integer overflow bugs such as Bug#8664.
16234 * frame.c (Fmouse_position, Fmouse_pixel_position):
16235 Use Time, not unsigned long, for user-interface timestamps.
16236 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
16237 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
16238 * keyboard.h (last_event_timestamp): Likewise.
16239 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
16240 * menu.h (xmenu_show): Likewise.
16241 * term.c (term_mouse_position): Likewise.
16242 * termhooks.h (struct input_event.timestamp): Likewise.
16243 (struct terminal.mouse_position_hook): Likewise.
16244 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
16245 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
16246 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
16247 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
16248 what it was before.
16249 * menu.h, termhooks.h: Include "systime.h", for Time.
16251 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
16252 Don't assume that the difference between two unsigned long values
16253 can fit into an integer. At this point, we know button_down_time
16254 <= event->timestamp, so the difference must be nonnegative, so
16255 there's no need to cast the result if double-click-time is
16256 nonnegative, as it should be; check that it's nonnegative, just in
16257 case. This bug is triggered when events are more than 2**31 ms
16258 apart (about 25 days). (Bug#8664)
16260 * xselect.c (last_event_timestamp): Remove duplicate decl.
16261 (x_own_selection): Remove needless cast to unsigned long.
16263 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
16264 that always fit in int. Use a sentinel instead of a counter, to
16265 avoid a temp and to allay GCC's concerns about possible int overflow.
16266 * frame.h (struct frame): Use int for menu_bar_items_used
16267 instead of EMACS_INT, since it always fits in int.
16269 * menu.c (grow_menu_items): Check for int overflow.
16271 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
16273 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
16274 Before, the code was not consistent. These values cannot exceed
16275 2**31 - 1 so there's no need to make them unsigned.
16276 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
16277 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
16278 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
16280 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
16282 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
16283 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
16284 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
16285 presumably because the widths might not match.
16287 * window.c (size_window): Avoid needless test at loop start.
16289 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
16291 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
16293 2011-05-12 Drew Adams <drew.adams@oracle.com>
16295 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
16297 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16299 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
16300 `width' to `bar_area_x' and `bar_area_width', respectively.
16301 (x_scroll_run): Take account of fringe background extension.
16303 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
16304 Rename local vars `left' and `width' to `bar_area_x' and
16305 `bar_area_width', respectively.
16306 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
16307 background extension.
16309 2011-05-10 Jim Meyering <meyering@redhat.com>
16311 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
16313 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
16315 * image.c (Finit_image_library): Return t for built-in image types,
16316 like pbm and xbm. (Bug#8640)
16318 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
16320 * w32menu.c (set_frame_menubar): Fix submenu allocation.
16322 2011-05-07 Eli Zaretskii <eliz@gnu.org>
16324 * w32console.c (Fset_screen_color): Doc fix.
16325 (Fget_screen_color): New function.
16326 (syms_of_ntterm): Defsubr it.
16328 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
16329 unlink the temporary file if Fcall_process didn't create it in the
16331 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
16332 child process will be redirected to a file specified with `:file'.
16333 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
16334 cue to call_process_cleanup not to close that handle.
16336 2011-05-07 Ben Key <bkey76@gmail.com>
16338 * makefile.w32-in: The bootstrap-temacs rule now makes use of
16339 one of two shell specific rules, either bootstrap-temacs-CMD or
16340 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
16341 to the previous implementation of the bootstrap-temacs rule.
16342 The bootstrap-temacs-CMD rule is similar to the previous
16343 implementation of the bootstrap-temacs rule except that it
16344 makes use of the ESC_CFLAGS variable instead of the CFLAGS
16347 These changes, along with some changes to nt/configure.bat,
16348 nt/gmake.defs, and nt/nmake.defs, are required to extend my
16349 earlier fix to add support for --cflags and --ldflags options
16350 that include quotes so that it works whether make uses cmd or
16353 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
16355 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
16356 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
16358 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
16359 a string. Handle both cases.
16360 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
16361 (Fdbus_register_method): Use Qinvalid_function.
16363 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
16365 * makefile.w32-in: Update dependencies.
16366 (LISP_H): Add inttypes.h and stdin.h.
16367 (PROCESS_H): Add unistd.h.
16369 2011-05-06 Eli Zaretskii <eliz@gnu.org>
16371 * lread.c: Include limits.h (fixes the MS-Windows build broken by
16372 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
16374 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
16376 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
16378 * term.c (vfatal): Remove stray call to va_end.
16379 It's not needed and the C Standard doesn't allow it here anyway.
16381 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
16382 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
16384 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
16387 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
16389 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
16391 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
16393 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
16395 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
16397 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
16398 * charset.c (Fdefine_charset_internal): Don't initialize
16399 charset.code_space[15]. The value was garbage, on hosts with
16400 32-bit int (Bug#8600).
16402 * lread.c (read_integer): Be more consistent with string-to-number.
16403 Use string_to_number to do the actual conversion; this avoids
16404 rounding errors and fixes some other screwups. Without this fix,
16405 for example, #x1fffffffffffffff was misread as -2305843009213693952.
16406 (digit_to_number): Move earlier, for benefit of read_integer.
16407 Return -1 if the digit is out of range for the base, -2 if it is
16408 not a digit in any supported base. (Bug#8602)
16410 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
16412 * dispnew.c (scrolling_window): Return 1 if we scrolled,
16413 to match comment at start of function. This also removes a
16414 GCC warning about overflow in a 32+64-bit port.
16416 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
16418 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
16419 Reported by Stefan Monnier in
16420 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
16421 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
16422 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
16424 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
16425 (EMACS_UINTPTR): Likewise, with uintptr_t.
16427 * lisp.h: Prefer 64-bit EMACS_INT if available.
16428 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
16429 on 32-bit hosts that have 64-bit int, so that they can access
16431 However, temporarily disable this change unless the temporary
16432 symbol WIDE_EMACS_INT is defined.
16434 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
16436 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
16437 This removes an assumption that EMACS_INT and long are the same
16438 width as pointers. The assumption is true for Emacs porting targets
16439 now, but we want to make other targets possible.
16440 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
16441 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
16442 In the rest of the code, change types of integers that hold casted
16443 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
16444 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
16445 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
16446 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
16447 No need to cast type when ORing.
16448 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
16449 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
16450 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
16451 assume EMACS_INT is the same width as char *.
16452 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
16453 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
16454 Remove no-longer-needed casts.
16455 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
16456 (xg_tool_bar_help_callback, xg_make_tool_item):
16457 Use EMACS_INTPTR to hold an integer
16458 that will be cast to void *; this can avoid a GCC warning
16459 if EMACS_INT is not the same width as void *.
16460 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
16461 * xdisp.c (display_echo_area_1, resize_mini_window_1):
16462 (current_message_1, set_message_1):
16463 Use a local to convert to proper width without a cast.
16464 * xmenu.c (dialog_selection_callback): Likewise.
16466 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
16467 Also, don't assume VALBITS / RAND_BITS is less than 5,
16468 and don't rely on undefined behavior when shifting a 1 left into
16470 * lisp.h (get_random): Change signature to match.
16472 * lread.c (hash_string): Use size_t, not int, for hash computation.
16473 Normally we prefer signed values; but hashing is special, because
16474 it's better to use unsigned division on hash table sizes so that
16475 the remainder is nonnegative. Also, size_t is the natural width
16476 for hashing into memory. The previous code used 'int', which doesn't
16477 retain enough info to hash well into very large tables.
16478 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
16480 * dbusbind.c: Don't possibly lose pointer info when converting.
16481 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
16482 Use XPNTR rather than XHASH, so that the high-order bits of
16483 the pointer aren't lost when converting through void *.
16485 * eval.c (Fautoload): Don't double-shift a pointer.
16487 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
16489 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
16491 * gnutls.c (DEF_GNUTLS_FN):
16492 * image.c (DEF_IMGLIB_FN): Make function pointers static.
16494 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
16496 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
16499 2011-05-05 Eli Zaretskii <eliz@gnu.org>
16501 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
16502 New version that can reserve upto 2GB of heap space.
16504 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
16506 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
16508 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
16510 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
16511 `gnutls_certificate_set_x509_key_file'.
16513 2011-05-05 Juanma Barranquero <lekktu@gmail.com>

16570 * process.c: Include lisp.h before w32.h, not after.
16571 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
16572 instead of gnutls_record_check_pending.
16574 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
16576 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>

16624 rather than `XVECTOR (FOO)->size'.
16626 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
16627 inttypes.h, as a gnulib replacement is used if it not available in
16630 2011-04-21 Eli Zaretskii <eliz@gnu.org>

16649 %llo or %llx format is passed. (Bug#8545)
16651 * window.c (window_scroll_line_based): Use a marker instead of
16652 simple variables to record original value of point. (Bug#7952)

16655 produced by %s or %c overflows available buffer space. (Bug#8545)
16657 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
16659 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
16660 (SIZE_MAX): Move defn after all includes, as they might #define it.
16662 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
16664 * w32.c (init_environment): Warn about defaulting HOME to C:\.
16666 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
16668 * keyboard.c (Qdelayed_warnings_hook): Define.
16669 (command_loop_1): Run `delayed-warnings-hook'
16670 if Vdelayed_warnings_list is non-nil.
16671 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
16672 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
16674 2011-04-28 Eli Zaretskii <eliz@gnu.org>
16676 * doprnt.c (doprnt): Don't return value smaller than the buffer
16677 size if the message was truncated. (Bug#8545).
16679 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
16681 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
16682 (Fx_window_property): #if-0 the whole functions, not just the bodies.
16684 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
16686 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
16688 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
16690 * makefile.w32-in: Update dependencies.
16692 2011-04-27 Eli Zaretskii <eliz@gnu.org>
16694 Improve `doprnt' and its usage. (Bug#8545)
16695 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
16696 `format_end'. Remove support for %l as a conversion specifier.
16697 Don't use xrealloc. Improve diagnostics when the %l size modifier
16698 is used. Update the commentary.
16700 * eval.c (verror): Simplify calculation of size_t.
16702 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
16705 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
16707 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
16710 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
16712 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
16713 This makes this file independent of the recent pseudovector change.
16715 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
16717 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
16719 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
16720 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
16721 Remove unused local.
16722 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
16724 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
16725 GCC 4.6.0 optimizes based on type-based alias analysis.
16726 For example, if b is of type struct buffer * and v of type struct
16727 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
16728 != &v->size, and therefore "v->size = 1; b->size = 2; return
16729 v->size;" must therefore return 1. This assumption is incorrect
16730 for Emacs, since it type-puns struct Lisp_Vector * with many other
16731 types. To fix this problem, this patch adds a new type struct
16732 vectorlike_header that documents the constraints on layout of vectors
16733 and pseudovectors, and helps optimizing compilers not get fooled
16734 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
16735 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
16736 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
16738 (XSETPVECTYPE): Rewrite in terms of new macro.
16739 (XSETPVECTYPESIZE): New macro, specifying both type and size.
16740 This is a bit clearer, and further avoids the possibility of
16741 undesirable aliasing.
16742 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
16743 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
16744 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
16745 since Lisp_Subr is a special case (no "next" field).
16746 (ASIZE): Now uses header.size rather than size.
16747 All previous uses of XVECTOR (foo)->size replaced to use this macro,
16748 to avoid the hassle of writing XVECTOR (foo)->header.size.
16749 (struct vectorlike_header): New type.
16750 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
16751 object, to help avoid aliasing.
16752 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
16753 (SUBRP): Likewise, since Lisp_Subr is a special case.
16754 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
16755 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
16756 (struct Lisp_Hash_Table): Combine first two members into a single
16757 struct vectorlike_header member. All uses of "size" and "next" members
16758 changed to be "header.size" and "header.next".
16759 * buffer.h (struct buffer): Likewise.
16760 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
16761 * frame.h (struct frame): Likewise.
16762 * process.h (struct Lisp_Process): Likewise.
16763 * termhooks.h (struct terminal): Likewise.
16764 * window.c (struct save_window_data, struct saved_window): Likewise.
16765 * window.h (struct window): Likewise.
16766 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
16767 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
16768 * buffer.c (init_buffer_once): Likewise.
16769 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
16771 * process.c (Fformat_network_address): Use local var for size,
16774 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
16776 Make the Lisp reader and string-to-float more consistent (Bug#8525)
16777 * data.c (atof): Remove decl; no longer used or needed.
16778 (digit_to_number): Move to lread.c.
16779 (Fstring_to_number): Use new string_to_number function, to be
16780 consistent with how the Lisp reader treats infinities and NaNs.
16781 Do not assume that floating-point numbers represent EMACS_INT
16782 without losing information; this is not true on most 64-bit hosts.
16783 Avoid double-rounding errors, by insisting on integers when
16784 parsing non-base-10 numbers, as the documentation specifies.
16785 * lisp.h (string_to_number): New decl, replacing ...
16786 (isfloat_string): Remove.
16787 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
16788 (read1): Do not accept +. and -. as integers; this
16789 appears to have been a coding error. Similarly, do not accept
16790 strings like +-1e0 as floating point numbers. Do not report
16791 overflow for integer overflows unless the base is not 10 which
16792 means we have no simple and reliable way to continue.
16793 Break out the floating-point parsing into a new
16794 function string_to_number, so that Fstring_to_number parses
16795 floating point numbers consistently with the Lisp reader.
16796 (digit_to_number): Move here from data.c. Make it static inline.
16797 (E_CHAR, EXP_INT): Remove, replacing with ...
16798 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
16799 (string_to_number): New function, replacing isfloat_string.
16800 This function checks for valid syntax and produces the resulting
16801 Lisp float number too. Rework it so that string-to-number
16802 no longer mishandles examples like "1.0e+". Use strtoumax,
16803 so that overflow for non-base-10 numbers is reported only when
16804 there's no portable and simple way to convert to floating point.
16806 * textprop.c (set_text_properties_1): Rewrite for clarity,
16807 and to avoid GCC warning about integer overflow.
16809 * intervals.h (struct interval): Use EMACS_INT for members
16810 where EMACS_UINT might cause problems. See
16811 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
16812 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
16813 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
16815 (offset_intervals): Tell GCC not to worry about length overflow
16816 when negating a negative length.
16818 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
16819 (overrun_check_free): Likewise.
16821 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
16822 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
16825 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
16826 (gnutls_make_error): Rename local to avoid shadowing.
16827 (gnutls_emacs_global_deinit): ifdef out; not used.
16828 (Fgnutls_boot): Use const for pointer to readonly storage.
16829 Comment out unused local. Fix pointer signedness problems.
16831 * lread.c (openp): Don't stuff size_t into an 'int'.
16832 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
16833 about possible signed overflow.
16835 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
16836 (GDK_KEY_g): Don't define if already defined.
16837 (xg_prepare_tooltip): Avoid pointer signedness problem.
16838 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
16840 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
16841 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
16843 * xfns.c (Fx_window_property): Simplify a bit,
16844 to make a bit faster and to avoid GCC 4.6.0 warning.
16845 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
16847 * fns.c (internal_equal): Don't assume size_t fits in int.
16849 * alloc.c (compact_small_strings): Tighten assertion a little.
16851 Replace pEd with more-general pI, and fix some printf arg casts.
16852 * lisp.h (pI): New macro, generalizing old pEd macro to other
16853 conversion specifiers. For example, use "...%"pI"d..." rather
16854 than "...%"pEd"...".
16855 (pEd): Remove. All uses replaced with similar uses of pI.
16856 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
16857 * alloc.c (check_pure_size): Don't overflow by converting size to int.
16858 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
16859 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
16860 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
16861 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
16862 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
16864 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
16865 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
16866 * print.c (safe_debug_print, print_object): Likewise.
16867 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
16869 Use pI instead of if-then-else-abort. Use %p to avoid casts,
16870 avoiding the 0 flag, which is not portable.
16871 * process.c (Fmake_network_process): Use pI to avoid cast.
16872 * region-cache.c (pp_cache): Likewise.
16873 * xdisp.c (decode_mode_spec): Likewise.
16874 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
16875 behavior on 64-bit hosts with printf arg.
16876 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
16877 (x_stop_queuing_selection_requests): Likewise.
16878 (x_get_window_property): Don't truncate byte count to an 'int'
16881 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
16882 here, since it parses constructs like leading '-' and spaces,
16883 which are not wanted; and it overflows with large numbers.
16884 Instead, simply match F[0-9]+, which is what is wanted anyway.
16886 * alloc.c: Remove unportable assumptions about struct layout.
16887 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
16888 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
16889 (allocate_vectorlike, make_pure_vector): Use the new macros,
16890 plus offsetof, to remove unportable assumptions about struct layout.
16891 These assumptions hold on all porting targets that I know of, but
16892 they are not guaranteed, they're easy to remove, and removing them
16893 makes further changes easier.
16895 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
16896 This doesn't fix a bug but makes the code clearer.
16897 (string_overrun_cookie): Now const. Use initializers that
16898 don't formally overflow signed char, to avoid warnings.
16899 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
16900 can cause Emacs to crash when string overrun checking is enabled.
16901 (allocate_buffer): Don't assume sizeof (struct buffer) is a
16902 multiple of sizeof (EMACS_INT); it need not be, if
16903 alignof(EMACS_INT) < sizeof (EMACS_INT).
16904 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
16906 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
16908 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
16910 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
16912 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
16913 supposed to be handshaking. (Bug#8556)
16914 Reported by Paul Eggert <eggert@cs.ucla.edu>.
16916 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
16918 * lisp.h (Qdebug): List symbol.
16919 * eval.c (Qdebug): Restore global linkage.
16920 * keyboard.c (debug-on-event): New variable.
16921 (handle_user_signal): Break into debugger when debug-on-event
16922 matches the current signal symbol.
16924 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
16926 * alloc.c (check_sblock, check_string_bytes)
16927 (check_string_free_list): Convert to standard C.
16929 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>

17486 * fontset.h (face_suitable_for_char_p): Remove decl.
17487 * xfaces.c (face_at_string_position):
17488 Use FACE_SUITABLE_FOR_ASCII_CHAR_P, not FACE_SUITABLE_FOR_CHAR_P,
17489 since 0 is always ASCII.

17655 * xdisp.c (message_enable_multibyte): Now static.
17657 Declare Lisp_Object Q* variables to be 'static' if not exported.
17658 This makes it easier for human readers (and static analyzers)
17659 to see whether these variables are used from other modules.
17660 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:

17673 * lisp.h (DEFINE_FUNC): Make sname 'static'.
17675 Make Emacs functions such as Fatom 'static' by default.
17676 This makes it easier for human readers (and static analyzers)
17677 to see whether these functions can be called from other modules.
17678 DEFUN now defines a static function. To make the function external
17679 so that it can be used in other C modules, use the new macro DEFUE.

17681 (Finit_image_library):
17682 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):

17685 Remove decls, since these functions are now static.
17686 (Funintern, Fget_internal_run_time): New decls, since these functions
17687 were already external.
17689 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:

17696 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
17697 Mark functions with DEFUE instead of DEFUN,
17698 if they are used in other modules.
17699 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
17700 decls for now-static functions.
17701 * buffer.h (Fdelete_overlay): Remove decl.

17737 2011-04-13 Eli Zaretskii <eliz@gnu.org>
17739 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
17740 when at ZV. (Bug#8487)
17742 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
17744 * charset.c (Fclear_charset_maps): Use xfree instead of free.

17753 (overrun_check_free): Protoize.
17755 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
17757 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
17758 since callers should never pass a negative size.
17759 Change the signature to match that of plain 'read' and 'write'; see
17760 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
17761 * lisp.h: Update prototypes of emacs_write and emacs_read.
17763 2011-04-11 Eli Zaretskii <eliz@gnu.org>
17765 * xdisp.c (redisplay_window): Don't try to determine the character
17766 position of the scroll margin if the window start point w->startp
17767 is outside the buffer's accessible region. (Bug#8468)
17769 2011-04-10 Eli Zaretskii <eliz@gnu.org>
17771 Fix write-region and its subroutines for buffers > 2GB.
17772 * fileio.c (a_write, e_write): Modify declaration of arguments and
17773 local variables to support buffers larger than 2GB.
17774 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
17776 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
17777 argument, local variables, and return value.
17779 * lisp.h: Update prototypes of emacs_write and emacs_read.
17781 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
17783 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
17785 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
17787 Fix more problems found by GCC 4.6.0's static checks.
17789 * xdisp.c (vmessage): Use a better test for character truncation.
17791 * charset.c (load_charset_map): <, not <=, for optimization,
17792 and to avoid potential problems with integer overflow.
17793 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
17794 * casetab.c (set_identity, shuffle): Likewise.
17795 * editfns.c (Fformat): Likewise.
17796 * syntax.c (skip_chars): Likewise.
17798 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
17799 This also lets GCC 4.6.0 generate slightly better loop code.
17801 * callint.c (Fcall_interactively): <, not <=, for optimization.
17802 (Fcall_interactively): Count the number of arguments produced,
17803 not the number of arguments given. This is simpler and lets GCC
17804 4.6.0 generate slightly better code.
17806 * ftfont.c: Distingish more carefully between FcChar8 and char.
17807 The previous code passed unsigned char * to a functions like
17808 strlen and xstrcasecmp that expect char *, which does not
17809 conform to the C standard.
17810 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
17811 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
17812 char * when the C standard requires it.
17814 * keyboard.c (read_char): Remove unused var.
17816 * eval.c: Port to Windows vsnprintf (Bug#8435).
17817 Include <limits.h>.
17818 (SIZE_MAX): Define if the headers do not.
17819 (verror): Do not give up if vsnprintf returns a negative count.
17820 Instead, grow the buffer. This ports to Windows vsnprintf, which
17821 does not conform to C99. Problem reported by Eli Zaretskii.
17822 Also, simplify the allocation scheme, by avoiding the need for
17823 calling realloc, and removing the ALLOCATED variable.
17825 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
17827 Remove invocations of doprnt, as Emacs now uses vsnprintf.
17828 But keep the doprint source code for now, as we might revamp it
17829 and use it again (Bug#8435).
17830 * lisp.h (doprnt): Remove.
17831 * Makefile.in (base_obj): Remove doprnt.o.
17832 * deps.mk (doprnt.o): Remove.
17834 error: Print 32- and 64-bit integers portably (Bug#8435).
17835 Without this change, on typical 64-bit hosts error ("...%d...", N)
17836 was used to print both 32- and 64-bit integers N, which relied on
17837 undefined behavior.
17838 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
17839 * lisp.h (error, verror): Mark as printf-like functions.
17840 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
17841 Report overflow in size calculations when allocating printf buffer.
17842 Do not truncate output string at its first null byte.
17843 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
17844 Truncate the output at a character boundary, since vsnprintf does not
17846 * charset.c (check_iso_charset_parameter): Convert internal
17847 character to string before calling 'error', since %c now has the
17849 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
17850 overflow when computing char to be passed to 'error'. Do not
17851 pass Lisp_Object to 'error'; pass the integer instead.
17852 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
17853 formatted with plain %d.
17855 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
17857 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.

17869 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
17870 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
17871 return ssize_t not "int", and use size_t as the buffer length.
17872 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
17873 * gnutls.h: Update declarations.
17874 * process.c (read_process_output): Use ssize_t, to match.
17875 (send_process): Likewise.

17881 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
17883 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
17884 Use unsigned char, to match FcChar8 type definition.
17886 * xterm.c (handle_one_xevent):
17887 * xmenu.c (create_and_show_popup_menu):
17888 * xselect.c (x_decline_selection_request)

17987 * eval.c (Fsignal): Remove excess argument to 'fatal'.
17989 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
17990 This avoids several warnings with gcc -Wstrict-overflow.
17991 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
17992 directly, rather than having caller test rule sign. This avoids
17993 some unnecessary tests.
17994 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
17995 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
17996 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
17998 * xfont.c (xfont_text_extents): Remove var that was set but not used.
17999 (xfont_open): Avoid unnecessary tests.
18001 * composite.c (composition_gstring_put_cache): Use unsigned integer.
18003 * composite.h, composite.c (composition_gstring_put_cache):

18007 breaking out part of COMPOSITION_DECODE_RULE.
18008 (COMPOSITION_DECODE_RULE): Use it.

18010 by using the new macro.
18012 * textprop.c (set_text_properties_1): Change while to do-while,
18013 since the condition is always true at first.
18015 * intervals.c (graft_intervals_into_buffer): Mark var as used.
18016 (interval_deletion_adjustment): Return unsigned value.
18019 * process.c (list_processes_1, create_pty, read_process_output):

18035 * print.c (print_error_message): Avoid int overflow.
18037 * font.c (font_list_entities): Redo for clarity,
18038 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
18040 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
18041 (font_score): Avoid potential overflow in diff calculation.
18043 * fns.c (substring_both): Remove var that is set but not used.
18044 (sxhash): Redo loop for clarity and to avoid wraparound warning.
18046 * eval.c (funcall_lambda): Rename local to avoid shadowing.
18048 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
18049 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
18050 can always succeed if overflow has undefined behavior.
18052 * search.c (boyer_moore, wordify): Remove vars set but not used.
18053 (wordify): Omit three unnecessary tests.
18055 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
18056 All callers changed. This avoids the need for an unused var.
18058 * casefiddle.c (casify_region): Remove var that is set but not used.
18060 * dired.c (file_name_completion): Remove var that is set but not used.
18062 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
18064 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
18065 (Finsert_file_contents): Remove unnecessary code checking fd.
18067 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
18068 Check for integer overflow on size calculations.
18070 * buffer.c (Fprevious_overlay_change): Remove var that is set
18073 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
18074 Remove vars that are set but not used.
18075 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
18076 (timer_check_2): Mark vars as initialized.
18078 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
18080 * image.c (lookup_image): Remove var that is set but not used.
18081 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
18083 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
18084 that are set but not used.
18086 * xfns.c (make_invisible_cursor): Don't return garbage
18087 if XCreateBitmapFromData fails (Bug#8410).
18089 * xselect.c (x_get_local_selection, x_handle_property_notify):
18090 Remove vars that are set but not used.
18092 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
18093 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
18095 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
18096 Remove var that is set but not used.
18097 (scroll_bar_windows_size): Now size_t, not int.
18098 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
18099 Check for overflow.
18101 * xfaces.c (realize_named_face): Remove vars that are set but not used.
18102 (map_tty_color) [!defined MSDOS]: Likewise.
18104 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
18106 * coding.c: Remove vars that are set but not used.

18110 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
18111 (decode_coding_charset): Remove vars that are set but not used.
18113 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
18114 that is set but not used.
18116 * print.c (print_object): Remove var that is set but not used.
18118 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
18119 The gnulib version avoids calling malloc in the usual case,
18120 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
18121 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
18122 * filelock.c (current_lock_owner): Likewise.
18123 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
18124 * sysdep.c: Include allocator.h, careadlinkat.h.
18125 (emacs_no_realloc_allocator): New static constant.
18126 (emacs_readlink): New function.
18127 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
18128 ../lib/careadlinkat.h.
18130 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
18132 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
18133 first non-nil return value).

18147 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
18148 and thereabouts. All callers changed.
18149 (get_per_char_metric): Remove parameter `f', unused since
18150 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
18152 2011-04-02 Jim Meyering <meyering@redhat.com>
18154 do not dereference NULL upon failed strdup
18155 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
18156 (ns_get_family): Likewise.

18160 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
18162 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
18164 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or

18184 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
18186 * keyboard.c (eval_dyn): New fun.
18187 (menu_item_eval_property): Use it.

18191 * fns.c (concat, mapcar1): Accept byte-code-functions.
18193 * eval.c (Fsetq): Handle lexical vars.
18194 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
18195 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
18196 (FletX, Flet): Obey lexical binding.
18197 (Fcommandp): Handle closures.
18198 (Feval): New `lexical' arg.
18199 (eval_sub): New function extracted from Feval. Use it almost
18200 everywhere where Feval was used. Look up vars in lexical env.
18202 (Ffunctionp): Move from subr.el.
18203 (Ffuncall): Handle closures.
18204 (apply_lambda): Remove `eval_flags'.
18205 (funcall_lambda): Handle closures and new byte-code-functions.
18206 (Fspecial_variable_p): New function.
18207 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
18208 but without exporting it to Lisp.
18210 * doc.c (Fdocumentation, store_function_docstring):
18211 * data.c (Finteractive_form): Handle closures.
18213 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
18216 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
18218 (exec_byte_code): New function extracted from Fbyte_code to handle new
18219 calling convention for byte-code-functions. Add new byte-codes.
18221 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
18223 * alloc.c (Fmake_symbol): Init new `declared_special' field.

18232 (try_scrolling): Use it when setting scroll_limit.
18233 Limit scrolling to 100 screen lines.
18234 (redisplay_window): Even when falling back on "recentering",
18235 position point in the window according to scroll-conservatively,
18236 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
18238 (try_scrolling): When point is above the window, allow searching
18239 as far as scroll_max, or one screenful, to compute vertical
18240 distance from PT to the scroll margin position. This prevents
18241 try_scrolling from unnecessarily failing when
18242 scroll-conservatively is set to a value slightly larger than the
18243 window height. Clean up the case of PT below the margin at bottom
18244 of window: scroll_max can no longer be INT_MAX. When aggressive
18245 scrolling is in use, don't let point enter the opposite scroll
18246 margin as result of the scroll.
18247 (syms_of_xdisp) <scroll-conservatively>: Document the
18248 threshold of 100 lines for never-recentering scrolling.

18256 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
18257 (redisplay_internal): Remove parameter `preserve_echo_area',
18258 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
18260 * indent.c (Fvertical_motion):
18261 * window.c (window_scroll_pixel_based, Frecenter):
18262 Don't pass `need_y_p' to `move_it_by_lines'.
18264 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
18266 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
18267 steal a few bits to be more compact.
18268 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
18269 Remove unneeded casts.
18271 * bytecode.c (Fbyte_code): CAR and CDR can GC.
18273 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
18275 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
18276 binding" message (bug#7967).
18278 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
18280 Fix more problems found by GCC 4.6.0's static checks.
18282 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
18283 Remove unused local var.
18285 * editfns.c (Fmessage_box): Remove unused local var.
18287 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
18288 (note_mode_line_or_margin_highlight, note_mouse_highlight):
18289 Omit unused local vars.
18290 * window.c (shrink_windows): Omit unused local var.
18291 * menu.c (digest_single_submenu): Omit unused local var.
18292 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
18293 Omit unused local var.
18295 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
18296 Don't assume string length fits in int.
18297 (keyremap_step, read_key_sequence): Use size_t for sizes.
18298 (read_key_sequence): Don't check last_real_key_start redundantly.
18300 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
18301 instead of alloca (Bug#8344).
18303 * eval.c (Fbacktrace): Don't assume nargs fits in int.
18304 (Fbacktrace_frame): Don't assume nframes fits in int.
18306 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
18308 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
18311 * term.c (produce_glyphless_glyph): Remove unnecessary test.
18313 * cm.c (calccost): Turn while-do into do-while, for clarity.
18315 * keyboard.c (syms_of_keyboard): Use the same style as later
18316 in this function when indexing through an array. This also
18317 works around GCC bug 48267.
18319 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
18321 * xselect.c (x_check_property_data): Return correct size (Bug#8335).

18324 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
18326 * keyboard.c, keyboard.h (num_input_events): Now size_t.
18327 This avoids undefined behavior on integer overflow, and is a bit
18328 more convenient anyway since it is compared to a size_t variable.
18330 Variadic C functions now count arguments with size_t, not int.
18331 This avoids an unnecessary limitation on 64-bit machines, which
18332 caused (substring ...) to crash on large vectors (Bug#8344).
18333 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
18334 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
18335 All variadic functions and their callers changed accordingly.
18336 (struct gcpro.nvars): Now size_t, not int. All uses changed.
18337 * data.c (arith_driver, float_arith_driver): Likewise.
18338 * editfns.c (general_insert_function): Likewise.

18340 (internal_condition_case_n, run_hook_with_args, apply_lambda)
18341 (funcall_lambda, mark_backtrace): Likewise.
18342 * fns.c (concat): Likewise.
18343 * frame.c (x_set_frame_parameters): Likewise.
18344 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
18345 0 if not found, not -1. All callers changed.
18347 * alloc.c (garbage_collect): Don't assume stack size fits in int.
18348 (stack_copy_size): Now size_t, not int.
18349 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.

18354 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
18355 All callers changed.
18357 * lisp.h (multibyte_char_to_unibyte):
18358 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
18359 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
18360 * character.h (CHAR_TO_BYTE8):
18361 * cmds.c (internal_self_insert):
18362 * editfns.c (general_insert_function):
18363 * keymap.c (push_key_description):
18364 * search.c (Freplace_match):
18365 * xdisp.c (message_dolog, set_message_1): All callers changed.
18367 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
18369 * keyboard.c (safe_run_hook_funcall): New function.
18370 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
18371 don't set the hook to nil, but remove the offending function instead.
18372 (Qcommand_hook_internal): Remove, unused.
18373 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
18374 Vcommand_hook_internal.
18376 * eval.c (enum run_hooks_condition): Remove.
18377 (funcall_nil, funcall_not): New functions.
18378 (run_hook_with_args): Call each function through a `funcall' argument.
18379 Remove `cond' argument, now redundant.

18381 (Frun_hook_with_args_until_failure): Adjust accordingly.
18382 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.

18388 * print.c (strout): Remove parameter `multibyte', unused since
18389 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
18391 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
18392 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
18393 All callers changed.
18395 * w32.c (_wsa_errlist): Use braces for struct initializers.

18405 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
18406 All callers changed.
18408 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
18410 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.

18443 * w32.c (read_unc_volume): Use parameter `henum', instead of
18444 global variable `wget_enum_handle'.
18446 * keymap.c (describe_vector): Remove parameters `indices' and

18464 * process.c (wait_reading_process_output):
18465 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
18467 * insdel.c (adjust_markers_gap_motion):
18468 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.

18542 2011-03-23 Julien Danjou <julien@danjou.info>
18544 * term.c (Fsuspend_tty, Fresume_tty):
18545 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
18546 * window.c (temp_output_buffer_show):
18547 * insdel.c (signal_before_change):
18548 * frame.c (Fhandle_switch_frame):
18549 * fileio.c (Fdo_auto_save):
18550 * emacs.c (Fkill_emacs):
18551 * editfns.c (save_excursion_restore):
18552 * cmds.c (internal_self_insert):
18553 * callint.c (Fcall_interactively):
18554 * buffer.c (Fkill_all_local_variables):
18555 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
18557 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
18558 unconditionally since it does the check itself.
18560 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
18562 Fix more problems found by GCC 4.5.2's static checks.
18564 * coding.c (encode_coding_raw_text): Avoid unnecessary test
18565 the first time through the loop, since we know p0 < p1 then.
18566 This also avoids a gcc -Wstrict-overflow warning.
18568 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
18569 leading to a memory leak, possible in functions like
18570 load_charset_map_from_file that can allocate an unbounded number
18571 of objects (Bug#8318).
18573 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
18574 that could (at least in theory) be that large.
18576 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
18577 This is less likely to overflow, and avoids undefined behavior if
18578 overflow does occur. All callers changed. Use strtoul to scan
18579 for the unsigned long integer.
18580 (pint2hrstr): Simplify and tune code slightly.
18581 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

18589 This also avoids a warning with gcc -Wstrict-overflow.
18591 * fileio.c (Fcopy_file): Report error if fchown or fchmod
18594 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
18596 * process.c (Fmake_network_process): Use socklen_t, not int,
18597 where POSIX says socklen_t is required in portable programs.
18598 This fixes a porting bug on hosts like 64-bit HP-UX, where
18599 socklen_t is wider than int (Bug#8277).
18600 (Fmake_network_process, server_accept_connection):
18601 (wait_reading_process_output, read_process_output):
18604 * process.c: Rename or move locals to avoid shadowing.

18606 (read_process_output_error_handler, exec_sentinel_error_handler):
18607 Rename or move locals.
18608 (Fmake_network_process): Define label "retry_connect" only if needed.
18609 (Fnetwork_interface_info): Fix pointer signedness.

18611 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
18612 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
18614 Make tparam.h and terminfo.c consistent.
18615 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
18616 Include tparam.h instead, since it declares them.
18617 * cm.h (PC): Remove extern decl; tparam.h now does this.
18618 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
18619 * terminfo.c: Include tparam.h, to check interfaces.
18620 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
18621 (tparam): Adjust signature to match interface in tparam.h;
18622 this removes some undefined behavior. Check that outstring and len
18623 are zero, which they always are with Emacs.
18624 * tparam.h (PC, BC, UP): New extern decls.
18626 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
18627 (xftfont_open): Rename locals to avoid shadowing.
18629 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
18630 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
18631 (OTF_TAG_SYM): Omit macro if not needed.

18633 (get_adstyle_property, ftfont_pattern_entity):
18634 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
18635 Rename locals to avoid shadowing.
18637 * xfont.c (xfont_list_family): Mark var as initialized.
18639 * xml.c (make_dom): Now static.
18641 * composite.c (composition_compute_stop_pos): Rename local to
18643 (composition_reseat_it): Remove unused locals.
18644 (find_automatic_composition, composition_adjust_point): Likewise.
18645 (composition_update_it): Mark var as initialized.
18646 (find_automatic_composition): Mark vars as initialized,
18647 with a FIXME (Bug#8290).
18649 character.h: Rename locals to avoid shadowing.
18650 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
18651 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
18652 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
18653 (BUF_DEC_POS): Be more systematic about renaming local temporaries
18654 to avoid shadowing.
18656 * textprop.c (property_change_between_p): Remove; unused.
18658 * intervals.c (interval_start_pos): Now static.
18660 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".
18662 * atimer.c (start_atimer, append_atimer_lists, set_alarm):
18663 Rename locals to avoid shadowing.
18665 * sound.c (wav_play, au_play, Fplay_sound_internal):
18666 Fix pointer signedness.
18667 (alsa_choose_format): Remove unused local var.
18668 (wav_play): Initialize a variable to 0, to prevent undefined
18669 behavior (Bug#8278).
18671 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
18673 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
18675 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
18676 clobbering (Bug#8298).
18677 * sysdep.c (sys_subshell): Likewise.
18678 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
18680 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
18681 This should get cleaned up, so that child_setup has the
18682 same signature on all platforms.
18684 * callproc.c (call_process_cleanup): Now static.
18685 (relocate_fd): Rename locals to avoid shadowing.
18687 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
18689 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
18690 not to be necessary, and produces flickering.
18692 2011-03-20 Glenn Morris <rgm@gnu.org>
18694 * config.in: Remove file.
18696 2011-03-20 Juanma Barranquero <lekktu@gmail.com>

18710 * xfaces.c (Fx_load_color_file):
18711 Read color file from absolute filename (bug#8250).
18713 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
18715 * makefile.w32-in: Update dependencies.
18717 2011-03-17 Eli Zaretskii <eliz@gnu.org>

18797 * alloc.c (mark_backtrace): Move decl from here ...
18798 * lisp.h: ... to here, so that it can be checked.
18800 * eval.c (call_debugger, do_debug_on_call, grow_specpdl): Now static.
18801 (Fdefvar): Rewrite so as not to use empty "else".

18806 * callint.c (quotify_arg, quotify_args): Now static.
18807 (Fcall_interactively): Rename locals to avoid shadowing.

18815 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
18816 some of which prompt warnings from gcc -Wbad-function-cast.
18817 (Fformat_time_string, Fencode_time, Finsert_char):
18818 (Ftranslate_region_internal, Fformat):

18846 (Fmemory_limit): Cast sbrk's returned value to char *.
18848 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
18849 avoids undefined behavior in theory.
18851 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
18853 Use functions, not macros, for up- and down-casing (Bug#8254).
18854 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
18855 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
18856 to use the following functions instead of these macros.
18857 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
18858 EMACS_INT, since callers assume the returned value fits in int.
18859 (upcase1): Likewise, for UPCASE_TABLE.
18860 (uppercasep, lowercasep, upcase): New static inline functions.
18861 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

18867 (regex_compile, re_search_2, re_match_2_internal):
18868 Remove unused local vars.

18870 which gcc can warn about.
18871 (regex_compile, re_match_2_internal): Mark locals as initialized.
18872 (RETALLOC_IF): Define only if needed.
18873 (WORDCHAR_P): Likewise. This one is never needed, but is used
18874 only in a comment talking about a compiler bug, so put inside
18875 the #if 0 of that comment.
18876 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
18877 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
18880 * search.c (boyer_moore): Rename locals to avoid shadowing.

18895 Rename locals to avoid shadowing.
18896 (Fvertical_motion): Mark locals as initialized.
18898 * casefiddle.c (casify_object, casify_region): Now static.
18899 (casify_region): Mark local as initialized.

18903 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
18904 New macros, so that the caller can use some names other than
18905 gcpro1, gcpro2, etc.
18906 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
18908 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
18909 argument, for consistency with GCPRO2_VAR, etc: it is now the
18910 prefix of the variable, not the variable itself. All uses
18912 * dired.c (directory_files_internal, file_name_completion):
18913 Rename locals to avoid shadowing.
18915 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
18916 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
18917 dired.c's scmp function, had undefined behavior.
18918 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
18919 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
18920 * buffer.h: ... to here, because these macros use current_buffer,
18921 and the new implementation with inline functions needs to have
18922 current_buffer in scope now, rather than later when the macros
18924 (downcase, upcase1): New static inline functions.
18925 (DOWNCASE, UPCASE1): Reimplement using these functions.
18926 This avoids undefined behavior in expressions like
18927 DOWNCASE (x) == DOWNCASE (y), which previously suffered
18928 from race conditions in accessing the global variables
18929 case_temp1 and case_temp2.
18930 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
18931 * lisp.h (case_temp1, case_temp2): Remove their decls.
18932 * character.h (ASCII_CHAR_P): Move from here ...
18933 * lisp.h: ... to here, so that the inline functions mentioned
18934 above can use them.
18936 * dired.c (directory_files_internal_unwind): Now static.
18938 * fileio.c (file_name_as_directory, directory_file_name):
18939 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
18941 (file_name_as_directory): Use const pointers when appropriate.
18942 (Fexpand_file_name): Likewise. In particular, newdir might
18943 point at constant storage, so make it a const pointer.
18944 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
18945 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
18947 (Fset_file_times, Finsert_file_contents, auto_save_error):
18948 Rename locals to avoid shadowing.

18951 (Ftry_completion, Fall_completions): Rename or remove locals
18952 to avoid shadowing.
18954 * marker.c (bytepos_to_charpos): Remove; unused.
18956 * lisp.h (verify_bytepos, count_markers): New decls,
18957 so that gcc does not warn that these functions aren't declared.
18959 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
18960 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
18961 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
18962 (copy_text): Remove unused local var.
18964 * filelock.c (within_one_second): Now static.
18965 (lock_file_1): Rename local to avoid shadowing.
18967 * buffer.c (fix_overlays_before): Mark locals as initialized.
18968 (fix_start_end_in_overlays): Likewise. This function should be
18969 simplified by using pointers-to-pointers, but that's a different
18971 (switch_to_buffer_1): Now static.
18972 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
18973 (report_overlay_modification): Rename locals to avoid shadowing.
18975 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
18976 Fix pointer signedness issue.
18977 (sys_subshell): Mark local as volatile if checking for lint,
18978 to suppress a gcc -Wclobbered warning that does not seem to be right.
18979 (MAXPATHLEN): Define only if needed.
18981 * process.c (serial_open, serial_configure): Move decls from here ...
18982 * systty.h: ... to here, so that they can be checked.
18984 * fns.c (get_random, seed_random): Move extern decls from here ...
18985 * lisp.h: ... to here, so that they can be checked.
18987 * sysdep.c (reset_io): Now static.
18988 (wait_for_termination_signal): Remove; unused.
18990 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
18991 (copy_keymap_item, append_key, push_text_char_description):
18993 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
18994 (DENSE_TABLE_SIZE): Remove; unused.
18995 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
18996 (describe_map_tree):
18997 Rename locals to avoid shadowing.
18999 * keyboard.c: Declare functions static if they are not used elsewhere.
19000 (echo_char, echo_dash, cmd_error, top_level_2):
19001 (poll_for_input, handle_async_input): Now static.
19002 (read_char, kbd_buffer_get_event, make_lispy_position):
19003 (make_lispy_event, make_lispy_movement, apply_modifiers):
19004 (decode_keyboard_code, tty_read_avail_input, menu_bar_items):

19021 if GCC considers string literals to be constants.
19023 * lisp.h (fatal_error_signal): Add decl, since it's exported.

19084 (BUF_PT_BYTE): Rewrite to handle indirect buffers (Bug#8219).
19085 These macros can no longer be used for assignment.
19087 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):

19143 2011-03-12 Paul Eggert <eggert@cs.ucla.edu>
19145 Improve quality of tests for time stamp overflow.
19146 For example, without this patch (encode-time 0 0 0 1 1
19147 1152921504606846976) returns the obviously-bogus value (-948597
19148 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
19149 reports time overflow. See
19150 <http://lists.gnu.org/archive/html/emacs-devel/2011-03/msg00470.html>.
19151 * deps.mk (editfns.o): Depend on ../lib/intprops.h.
