30 Revert recent change for Bug#8855.
31 As reported by Harald Hanche-Olsen in
32 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00445.html>
33 the change introduces a further bug, of creating lots of zombie
34 processes in some cases. Further work is needed to come up with a
35 better fix for Bug#8855.
37 2012-11-24 Eli Zaretskii <eliz@gnu.org>
39 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
40 highlighting on the frame was cleared. Prevents assertion
41 violations when repeatedly clicking on the "Top" link of the
42 "bread-crumbs" in Info buffers.
44 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>
45 Eli Zaretskii <eliz@gnu.org>
47 Fix a race condition with glib (Bug#8855).
48 The symptom is a diagnostic "GLib-WARNING **: In call to
49 g_spawn_sync(), exit status of a child process was requested but
50 SIGCHLD action was set to SIG_IGN and ECHILD was received by
51 waitpid(), so exit status can't be returned." The diagnostic
52 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
53 The real bug is a race condition between Emacs and glib: Emacs
54 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
55 so that glib can't find it. Work around the bug by invoking
56 waitpid only on subprocesses that Emacs itself creates.
58 This is a backport from the trunk, consisting of:
60 * w32proc.c (create_child): Don't clip the PID of the child
61 process to fit into an Emacs integer, as this is no longer a
63 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
64 reaping only the process specified by PID argument, if that is
65 positive. Use PID instead of dead_child to know which process to
66 reap. Wait for the child to die only if WNOHANG is not in
68 (sys_select): Don't set dead_child.
70 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
71 as it is no longer needed.
73 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
75 (create_process, record_child_status_change): Don't use special
76 value -1 in pid field, as the caller now must know the pid rather
77 than having the callee infer it. The inference was sometimes
78 incorrect anyway, due to another race.
79 (create_process): Set new 'alive' member if child is created.
80 (process_status_retrieved): New function.
81 (record_child_status_change): Use it.
82 Accept negative 1st argument, which means to wait for the
83 processes that Emacs already knows about. Move special-case code
84 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
85 processes that have already been waited for, by testing and
86 clearing new 'alive' member. Remove the setting of
87 record_at_most_one_child for the !WNOHANG case.
88 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
89 now does this internally.
90 (handle_child_signal): Let record_child_status_change do all
91 the work, since we do not want to reap all exited child processes,
92 only the child processes that Emacs itself created.
93 * process.h (Lisp_Process): New boolean member 'alive'.
95 2012-11-23 Eli Zaretskii <eliz@gnu.org>
97 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
98 between bpos_covered and bpos_max. This fixes cursor display when
99 several display strings follow each other.
101 * .gdbinit (pgx): If the glyph's object is a string, display the
102 pointer to string data, rather than the value of the string object
103 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
105 2012-11-21 Eli Zaretskii <eliz@gnu.org>
107 * indent.c (Fvertical_motion): If the starting position is covered
108 by a display string, return to one position before that, to avoid
109 overshooting it inside move_it_to. (Bug#12930)
111 2012-11-20 Daniel Colascione <dancol@dancol.org>
113 * w32fns.c (Fx_file_dialog):
114 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
115 cygwin_convert_file_name*.
117 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
118 Rename cygwin_convert_path* to cygwin_convert_file_name*.
120 2012-11-20 Ken Brown <kbrown@cornell.edu>
122 * emacs.c (main): Set the G_SLICE environment variable for all
123 Cygwin builds, not just GTK builds. See
124 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
126 2012-11-19 Eli Zaretskii <eliz@gnu.org>
128 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Don't mix declaration of
129 w32_note_current_window with code. (Backport from trunk.)
131 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
132 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
133 Define for the MSVC compiler.
135 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing
138 2012-11-18 Eli Zaretskii <eliz@gnu.org>
140 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
141 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
142 dostounix_filename. Prevents crashes down the road, because
143 dostounix_filename assumes it gets a unibyte string. Reported by
144 Michel de Ruiter <michel@sentient.nl>, see
145 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html
147 2012-11-17 Eli Zaretskii <eliz@gnu.org>
149 * w32select.c: Include w32common.h before w32term.h, so that
150 windows.h gets included before w32term.h uses some of its
153 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]: New
155 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]: New
157 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
159 2012-11-17 Jan Djärv <jan.h.d@swipnet.se>
161 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
162 (ns_select): Return at once if events are held (Bug#12834).
164 2012-11-16 enami tsugutomo <tsugutomo.enami@jp.sony.com>
166 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
167 Needed following 2012-10-20 change. (Bug#12902)
169 2012-11-16 Glenn Morris <rgm@gnu.org>
171 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
173 2012-11-15 Stefan Monnier <monnier@iro.umontreal.ca>
175 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
177 2012-11-14 Eli Zaretskii <eliz@gnu.org>
179 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
180 use the same value of thread handle.
181 (start_timer_thread): If the timer thread exited (due to error),
182 clean up by closing the two handles it used. Duplicate the caller
183 thread's handle here, so it gets duplicated only once, when
184 launching the timer thread. Set priority of the timer thread, not
186 (getitimer): Don't duplicate the caller thread's handle here.
189 2012-11-13 Jan Djärv <jan.h.d@swipnet.se>
191 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
194 2012-11-12 Eli Zaretskii <eliz@gnu.org>
196 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
197 passed to pint2str and pint2hrstr to be at most the size of the
198 frame's decode_mode_spec_buffer. This avoids crashes with very
199 large values of FIELD_WIDTH argument to decode_mode_spec.
202 2012-11-07 Martin Rudalics <rudalics@gmx.at>
204 * window.c (Fsplit_window_internal): Set combination limit of
205 new parent window to t iff Vwindow_combination_limit is t;
206 fixing a regression introduced with the change from 2012-09-22.
207 (Fwindow_combination_limit, Fset_window_combination_limit):
210 2012-11-06 Eli Zaretskii <eliz@gnu.org>
212 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
213 amount when the scroll margins are too large. When scrolling
214 backwards in the buffer, give up if cannot reach point or the
215 scroll margin within a reasonable number of screen lines.
216 Fixes point position in window under scroll-up/down-aggressively when
217 point is positioned many lines beyond the window top/bottom.
220 2012-11-05 Eli Zaretskii <eliz@gnu.org>
222 * ralloc.c (relinquish): If real_morecore fails to return memory
223 to the system, don't crash; instead, leave the last heap
224 unchanged and return. (Bug#12774)
226 2012-11-03 Eli Zaretskii <eliz@gnu.org>
228 * lisp.mk: Adjust comments to the fact that term/internal is now
229 loaded from loadup.el.
231 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
232 (msdos_fatal_signal): New function.
233 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
236 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
237 for GCC versions before 4.
238 (emacs_raise): Define to call msdos_fatal_signal.
240 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
241 iterator when starting in the middle of a display or overlay
244 2012-11-03 Jan Djärv <jan.h.d@swipnet.se>
246 * widget.c (resize_cb): New function.
247 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
248 (EmacsFrameResize): Check if all is up to date before changing frame
251 2012-11-01 Eli Zaretskii <eliz@gnu.org>
253 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
255 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
257 Fix crash when using Emacs as commit editor for git (Bug#12697).
258 * callproc.c (setpgrp): Remove macro, as we now use setpgid
259 and it is configured in conf_post.h.
260 (Fcall_process): Don't invoke both setsid and setpgid; the former
261 is enough, if it exists.
262 * callproc.c (Fcall_process, child_setup):
263 * process.c (create_process): Use setpgid.
264 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
266 * dispnew.c (init_display): Initialize the foreground group
267 if we are running a tty display.
268 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
269 * lisp.h (init_foreground_group): New decl.
270 * sysdep.c (inherited_pgroup): New static var.
271 (init_foreground_group, tcsetpgrp_without_stopping)
272 (narrow_foreground_group, widen_foreground_group): New functions.
273 (init_sys_modes): Narrow foreground group.
274 (reset_sys_modes): Widen foreground group.
276 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
278 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
280 2012-10-31 Martin Rudalics <rudalics@gmx.at>
282 * minibuf.c (read_minibuf): Restore current buffer since
283 choose_minibuf_frame calling Fset_frame_selected_window may
284 change it (Bug#12766).
286 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
288 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
290 2012-10-30 Kenichi Handa <handa@gnu.org>
292 * font.c (Ffont_at): If WINDOW is specified and it is not
293 displaying the current buffer, signal an error.
295 2012-10-29 Daniel Colascione <dancol@dancol.org>
297 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
298 In preparation for fixing bug#12739, move these functions from
301 * coding.h, coding.c: ... to here, and compile them only when
302 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
303 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
305 2012-10-28 Eli Zaretskii <eliz@gnu.org>
307 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
308 (timer_loop, getitimer, setitimer): Use it instead of
309 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
311 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
314 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
316 * nsterm.m (NO_APPDEFINED_DATA): New define.
317 (last_appdefined_event_data): New variable
318 (last_appdefined_event): Remove.
319 (ns_select): Initialize t from last_appdefined_event_data instead
320 of [last_appdefined_event data1].
321 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
322 remove last_appdefined_event (Bug#12698).
324 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
326 * frame.c (x_set_font): Catch internal error.
328 2012-10-27 Eli Zaretskii <eliz@gnu.org>
330 Avoid overflow in w32 implementation of interval timers.
331 When possible, for ITIMER_PROF count only times the main thread
333 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
334 'volatile ULONGLONG' types. All the other data which was
335 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
336 (GetThreadTimes_Proc): New typedef.
337 (w32_get_timer_time): New function, returns a suitable time value
339 (timer_loop): Enter critical section when accessing ULONGLONG
340 values of the itimer_data struct, as these accesses are no longer
341 atomic. Call 'w32_get_timer_time' instead of 'clock'.
342 Remove unused variable.
343 (init_timers): Initialize s_pfn_Get_Thread_Times.
344 (start_timer_thread): Don't assign itimer->caller_thread here.
345 (getitimer): Assign itimer->caller_thread here.
346 (setitimer): Always call getitimer to get the value of ticks_now.
347 (sys_spawnve): Avoid compiler warning about format mismatch.
349 2012-10-26 Eli Zaretskii <eliz@gnu.org>
351 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
352 mouse movement events if the menu bar is active. This avoids
353 producing a busy "hour-glass" cursor by Windows if the mouse
354 pointer is positioned over a tooltip shown for some menu item.
356 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
358 Don't assume process IDs fit in int.
359 * emacs.c (shut_down_emacs) [!DOS_NT]:
360 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
361 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
362 Use pid_t, not int, to store process IDs, as 'int'
363 is not wide enough on a few platforms (e.g., AIX and IRIX).
365 2012-10-23 Kenichi Handa <handa@gnu.org>
367 The following change is to make face-font-rescale-alist work
368 correctly for non-ASCII fonts.
370 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
371 (font_open_for_lface): Handle Vface_font_rescale_alist.
373 2012-10-23 Chong Yidong <cyd@gnu.org>
375 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
377 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>
379 * nsfont.m (nsfont_open, ns_glyph_metrics): Force integer advancement
381 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
383 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
386 2012-10-21 Glenn Morris <rgm@gnu.org>
388 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
390 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
393 * frame.c (Fmouse_position, Fmouse_pixel_position):
394 * xdisp.c (produce_stretch_glyph):
395 Declare local vars only when they're needed.
396 This is clearer and avoids a warning on OpenBSD about unused vars.
397 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
398 This is safer, and avoids OpenBSD warnings about unused vars.
399 * keyboard.c (record_menu_key): Remove unnecessary decl.
400 (poll_timer): Define only if POLL_FOR_INPUT is defined.
401 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
402 as our definition clashes with OpenBSD's.
403 * xfaces.c (load_face_colors, check_lface_attrs)
404 (get_lface_attributes_no_remap, get_lface_attributes)
405 (lface_fully_specified_p, x_supports_face_attributes_p)
406 (tty_supports_face_attributes_p, face_fontset, realize_face)
407 (realize_x_face, realize_tty_face):
408 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
409 merely Lisp_Object *. This is more informative and avoids
410 a warning on OpenBSD about accessing beyond an object's size.
412 2012-10-20 Chong Yidong <cyd@gnu.org>
414 * lread.c (Fload): Doc fix (Bug#12592).
416 2012-10-19 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny change)
418 * font.c (Ffont_at): Fix previous change.
420 2012-10-19 Eli Zaretskii <eliz@gnu.org>
422 * puresize.h (BASE_PURESIZE): Bump the base value to 1700000.
423 See http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00593.html
426 * alloc.c (NSTATICS): Decrease to 0x800.
428 2012-10-19 Stefan Monnier <monnier@iro.umontreal.ca>
430 * fns.c (Fnreverse): Include the problem element when signalling an
433 2012-10-18 Jan Djärv <jan.h.d@swipnet.se>
435 * nsterm.m (ns_select): Check writefds before call to
436 FD_ISSET (Bug#12668).
438 2012-10-18 Daniel Colascione <dancol@dancol.org>
440 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
441 (staticpro): If we run out of staticpro slots, die with an
442 informative error instead of just calling emacs_abort.
444 2012-10-18 Martin Rudalics <rudalics@gmx.at>
446 Fix two flaws reported by Dmitry Antipov.
447 * window.c (Ftemp_output_buffer_show): Remove.
448 (Fwindow_vscroll, Fset_window_vscroll): Use decode_live_window.
449 (syms_of_window): Remove defsubr for Stemp_output_buffer_show.
451 2012-10-17 Eli Zaretskii <eliz@gnu.org>
453 * makefile.w32-in ($(BLD)/w32.$(O)):
454 ($(BLD)/vm-limit.$(O)):
456 ($(BLD)/unexw32.$(O)):
457 ($(BLD)/fileio.$(O)):
458 ($(BLD)/dispnew.$(O)): Update dependencies.
460 * w32term.h (w32_initialize_display_info, initialize_w32_display):
463 * w32proc.c: Include ctype.h.
465 * w32.h (init_environment, check_windows_init_file)
466 (syms_of_ntproc, syms_of_ntterm, dostounix_filename)
467 (unixtodos_filename, init_winsock, srandom, random, sys_pipe)
468 (set_process_dir, sys_spawnve, register_child, sys_sleep, getwd)
469 (sys_link): Add prototypes.
471 * w32.c: Include w32select.h.
472 (sys_access, e_malloc, sys_select): Add prototypes.
473 (emacs_gnutls_pull): 'timeout' is now EMACS_TIME, not struct timeval.
475 * vm-limit.c [WINDOWSNT]: Include w32heap.h.
477 * unexw32.c: Include lisp.h and w32.h.
479 * term.c [WINDOWSNT]: Include w32term.h.
481 * process.c [WINDOWSNT]: Add prototype of sys_select.
483 * fileio.c [WINDOWSNT]: Include w32.h.

487 * cygw32.c (Fcygwin_convert_path_to_windows)
488 (Fcygwin_convert_path_from_windows): Use EQ to compare 2
489 Lisp_Object values. (Bug#12661)
491 * w32fns.c (w32_msg_pump): Use XIL instead of casting an integer
492 to Lisp_Object. (Bug#12661)
494 2012-10-17 Kenichi Handa <handa@gnu.org>
496 * xdisp.c (reseat_1): Make the information stored in it->cmp_it
499 2012-10-17 Dmitry Antipov <dmantipov@yandex.ru>

502 reset its buffer pointer to NULL (Bug#12652).
504 2012-10-17 Dmitry Antipov <dmantipov@yandex.ru>
506 Do not verify indirection counters of killed buffers (Bug#12579).

697 * keyboard.c (timers_run, swallow_events)
698 (detect_input_pending_run_timers):
699 * process.c (wait_reading_process_output):
700 Use unsigned for counter where wraparound-on-overflow is desired,
701 since unsigned is guaranteed to have that behavior and signed is not.
702 (read_char): Use ptrdiff_t for string length.
703 (get_input_pending): Remove first argument, since it was always
704 the same pointer-to-int (now pointer-to-boolean) &input_pending,
705 and behave as if it had that value. Return new value of
706 input_pending. All callers changed.
707 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
708 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's

728 Clean out old termopts cruft.
729 * termopts.h (flow_control, meta_key): Remove unused decls.
730 * dispnew.c, indent.c, nsterm.m, term.c, xsettings.c, xsmfns.c:
731 Don't include termopts.h.
733 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>
735 * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers.
737 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>

748 2012-10-09 Eli Zaretskii <eliz@gnu.org>
750 * w32fns.c (w32_last_error): Change the return value to DWORD, to
751 match what GetLastError returns. Explain why the function is
754 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
755 'is_tooltip_frame', to avoid confusion with its global namesake.
757 2012-10-08 Daniel Colascione <dancol@dancol.org>
759 * xdisp.c (start_hourglass): Call w32_note_current_window when
760 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
761 build that caused Emacs to display the hourglass cursor forever.
763 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
764 which is broken under remote desktop, calculate the number of
765 colors available for a display based on the display's number of
766 planes and number of bits per pixel per plane. (bug#10397).
768 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
770 * nsfont.m (Vfonts_in_cache): New variable.
771 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
772 are used. Add cached fonts to Vfonts_in_cache.
773 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
775 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
777 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
779 (FONT_H): Define after FRAME_H.
780 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
783 * w32term.c: Remove leftover declaration of keyboard_codepage.
785 2012-10-08 Eli Zaretskii <eliz@gnu.org>
787 * makefile.w32-in (FONT_H): Add $(FRAME_H).
788 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
789 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
790 (GLOBAL_SOURCES): Add cygw32.c.
791 ($(BLD)/unexw32.$(O)):
793 ($(BLD)/w32console.$(O)):
794 ($(BLD)/w32fns.$(O)):
795 ($(BLD)/w32heap.$(O)):
796 ($(BLD)/w32menu.$(O)):
797 ($(BLD)/w32proc.$(O)): Add w32common.h.
799 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
801 (x_to_w32_color): Don't modify the argument, modify a copy instead.
803 2012-10-08 Daniel Colascione <dancol@dancol.org>
805 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
806 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
807 accidental message numbering hole. Change other messages to
810 * w32select.h (HAVE_W32SELECT): Remove.
812 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
813 w32common.h instead of w32heap.h.
815 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)

823 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
824 (w32_minor_version, w32_build_number, w32_subtype):
825 Remove duplicate definitions.
827 * w32fns.c: Include w32common.h; include w32heap.h only in
830 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
831 Use `report_file_error' instead of `error' in order to better
832 inform users of what went wrong. Increase NTGUI_UNICODE file
833 dialog box file name length to 32k, the maximum allowed by the NT
836 * w32common.h: New file.
837 (ROUND_UP, ROUND_DOWN, get_page_size)
838 (get_allocation_unit, get_processor_type, get_w32_major_version)
839 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
840 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
841 (OS_NT, os_subtype, cache_system_info): Move here.
843 * unexw32.c, unexcw.c: Include w32common.h.
845 * emacs.c (main): Use (defined (WINDOWSNT) || defined
846 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
847 to call syms_of_w32select.
849 * cygw32.h: Remove obsolete EXFUN declarations.
851 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
853 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
854 of w32inevt.o from SOME_MACHINE_OBJECTS.
856 2012-10-08 Daniel Colascione <dancol@dancol.org>
858 * image.c: Permanent fix for JPEG compilation issue --- limit
859 jpeglib `boolean' redefinition to Cygwin builds.
861 2012-10-08 Eli Zaretskii <eliz@gnu.org>
863 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
865 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
868 2012-10-08 Daniel Colascione <dancol@dancol.org>
870 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
871 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
872 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
873 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
874 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
875 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
876 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
877 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
878 now a supported configuration.
880 * Makefile.in: consolidate image variables into LIBIMAGE; add
881 W32_OBJ and W32_LIBS. Compile new files.
884 (_DebPrint) declare tracing facility for W32 debugging. We need
885 to unify tracing later.
887 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
888 unconditional use of W32 Unicode functions. Cygwin runs only on
889 100% Unicode operating systems.
891 * cygw32.c: New file. Define Cygwin-specific facilities.
892 (Fcygwin_convert_path_to_windows)
893 (Fcygwin_convert_path_from_windows): New user functions for
894 accessing Cygwin path-munging routines.
896 * cygw32.h: New file.
897 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
898 UTF-16LE strings temporarily inside non-Lisp-visible string
901 (w32_strerror): Just what it says on the tin.
903 * emacs.c: Make the NS fork-then-exec code for daemon-launching
904 also run for Cygwin; both systems have the same problem with using
905 GUI facilities in a forked child. Also call syms_of_cygw32,
906 syms_of_w32select in correct places.
908 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
909 needs fork-then-exec for daemon launching.
911 * font.h: Include frame.h.
913 * image.c: Use the image library cache machinery only when we're
914 compiling for native WINDOWSNT; Cygwin can use shared libraries
915 like any other Unixlike system.
917 * keyboard.c: Clarify a comment regarding the input loop.
919 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
920 functions directly instead of trying to detect at runtime that our
921 host operating system supports them. We make this change for two
922 reasons: Cygwin lacks support for the multibyte character
923 conversion functions used by the legacy menu code, and Cygwin
924 never needs to rely on non-Unicode APIs.
926 * unexw32.c (hinst): Declare extern.
928 * w32.c: Change header order;
929 (w32_strerror): Move to w32fns.c because we need it for
930 non-WINDOWSNT builds.
932 * w32.h: Add #error macro to make sure we don't include w32.h for
933 Cygwin builds. Remove w32select declarations.
935 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
936 w32fns.c. w32console.c is WINDOWSNT-only.
938 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
939 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
941 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
942 (w32_major_version, w32_minor_version, w32_build_number)
943 (os_subtype, sound_type): Define here
944 (w32_defined_color): Make color parameter const for consistency
945 with other _defined_color functions.
946 (w32_createwindow): Unconditionally call w32_init_class instead of
947 doing so only when hprevinst is non-NULL. Plumbing hprevinst
948 through the code is complex and unnecessary because class
949 registration is practically free.
950 (w32_name_of_message): New EMACSDEBUG-only function.
951 (Fset_message_beep): Move here
952 (Fx_open_connection): Require that the display name for Windows be
953 "w32" for consistency, emacsclient disambiguation, and maybe, one
954 day, multi-window-system support.
955 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
956 Cygwin files for W32 GUI facilities, since these clearly don't
959 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
960 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
961 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
962 (w32_last_error): Remove.
964 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
966 * w32heap.c (syspage_mask): Declare here.
967 (cache_system_info): Remove.
969 * w32inevt.c (faked_key): Define globally, not statically.
970 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
971 (w32_console_toggle_lock_key): Move to w32fns.c.
973 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
975 * w32proc.c (_DebPrint): Move to w32fns.c.
976 * w32select.c: Include string.h, stdio.h for Cygwin.
977 * w32select.h: New File.
979 * w32term.c: Include io.h for non-CYGWIN builds; needed for
981 (w32_message_fd): New variable. Under Cygwin, holds the file
982 descriptor the system used to tell us about pending thread
985 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
986 that prevented compilation under non-WINDOWSNT systems.
988 (w32_initialize): Open /dev/windows and assign it to
989 w32_message_fd. Provide w32 feature.
991 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
992 (WM_EMACS_INPUT_READY): add.
993 (prepend_msg, w32_message_fd): Declare globally.
996 (keyboard_handle): Use only when WINDOWSNT.
997 (notify_msg_ready): New function. Posts a message to the main
998 thread's message queue under CYGWIN, which wakes up the main
999 thread from select(2) by making the /dev/windows file descriptor
1000 ready. Under WINDOWSNT, it sets an event the same way the old
1003 (post, prepend_msg): Actually call notify_msg_ready instead of
1004 setting the input event directly.
1006 2012-10-07 Eli Zaretskii <eliz@gnu.org>
1008 * ralloc.c (relinquish): If a heap is ready to be relinquished,
1009 but it still has blocs in it, don't return it to the system,
1010 instead of aborting. (Bug#12402)
1012 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>

1049 defined as a macro, as is done in Solaris.
1050 (sys_siglist_entries): New macro.
1051 (save_strsignal): Use it.
1052 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
1053 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
1055 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
1057 * nsfns.m (Fx_create_frame): Call x_default_parameter with
1058 fullscreen/Fullscreen.
1060 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
1061 tobar_height is new.
1063 * nsterm.m (x_make_frame_visible): Check for fullscreen.
1064 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
1065 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.

1078 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
1080 2012-10-05 Eli Zaretskii <eliz@gnu.org>
1082 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
1084 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
1085 that time stamps of directories could also be changed.
1086 Don't request the too broad GENERIC_WRITE, only the more restrictive
1087 FILE_WRITE_ATTRIBUTES access rights.
1089 * fileio.c (Fset_file_times): Special-case ignoring errors for
1090 directories only on MSDOS, not on MS-Windows.
1092 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
1094 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
1096 2012-10-04 Eli Zaretskii <eliz@gnu.org>

1101 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
1103 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
1104 to avoid similar races.
1105 * keyboard.c (pending_signals): Now bool, not int.
1107 Port timers to OpenBSD, plus check for timer failures.
1108 OpenBSD problem reported by Han Boetes.

1111 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
1112 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
1113 like OpenBSD, which has timer_settime but does not declare it.
1114 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
1115 whether to use itimerspec-related primitives. All uses of
1116 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
1118 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
1120 * profiler.c (handle_profiler_signal): Fix a malloc race
1121 that caused Emacs to hang on Fedora 17 when profiling Lisp.

1125 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
1127 2012-10-02 Eli Zaretskii <eliz@gnu.org>
1129 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
1130 consistent with the change in return value of 'safe_strsignal'.
1132 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
1134 Prefer plain 'static' to 'static inline' (Bug#12541).
1135 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
1136 (bidi_set_sor_type, bidi_push_embedding_level)
1137 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)

1142 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
1143 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
1144 Now 'static', not 'static inline'.
1146 Count overruns when profiling; change units to ns.
1147 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
1148 Give extra weight to samples after overruns, to attempt to count
1149 the time more accurately.
1150 (setup_cpu_timer): Change sampling interval units from ms to ns, since
1151 the underlying primitives nominally do ns.
1152 (Fprofiler_cpu_start): Document the change. Mention that
1153 the sampling intervals are only approximate.
1155 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
1157 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
1159 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
1160 case for the special 0 coding-system.
1162 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
1163 (Fmake_overlay): Remove redundant tests.
1164 (fix_start_end_in_overlays): Remove redundant recentering.
1166 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
1168 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
1169 Update dependencies.
1171 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
1173 Fix a malloc race condition involving strsignal.
1174 A signal can arrive in the middle of a malloc, and Emacs's signal
1175 handler can invoke strsignal, which can invoke malloc, which is
1176 not portable. This race condition bug makes Emacs hang on GNU/Linux.
1177 Fix it by altering the signal handler so that it does not invoke
1179 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
1180 * process.c (status_message): Use const pointer, in case strsignal
1181 is #defined to safe_strsignal.
1182 * sysdep.c (sys_siglist, init_signals): Always define and
1183 initialize a substitute sys_siglist if the system does not define
1184 one, even if HAVE_STRSIGNAL.
1185 (safe_strsignal): Rename from strsignal. Always define,
1186 using sys_siglist. Return a const pointer.
1187 * syssignal.h (safe_strsignal): New decl.
1188 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
1190 2012-10-01 Eli Zaretskii <eliz@gnu.org>
1192 * w32proc.c (timer_loop): Fix code that waits for timer
1193 expiration, to avoid high CPU usage.
1195 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
1197 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
1198 (sweep_weak_table): Remove redundant prototypes.
1200 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
1202 * emacs.c: Move the inclusion of TERM_HEADER after including
1203 windows.h on WINDOWSNT. This avoids compilation problems with
1206 2012-10-01 Eli Zaretskii <eliz@gnu.org>
1208 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
1209 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
1210 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
1211 as the previous version used 'void *'.
1213 * ralloc.c (ROUNDUP): Fix last change.
1214 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
1217 * w32proc.c <disable_itimers>: New static flag.
1218 (init_timers): Initialize it to zero, after creating the critical
1219 sections used by the timer threads.
1220 (term_timers): Set to 1 before deleting the critical sections.
1221 (getitimer, setitimer): If disable_itimers is non-zero, return an
1222 error indication without doing anything. Reported by Fabrice
1223 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
1224 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
1226 [!HAVE_SETITIMER]: Behave as the previous version that didn't
1229 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
1230 term_ntproc after all the other bookkeeping, to get timers working
1231 as long as possible.
1233 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
1235 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
1236 Suggested by Juri Linkov in
1237 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
1239 Prefer plain 'static' to 'static inline' (Bug#12541).
1240 With static functions, modern compilers inline pretty well by
1241 themselves; advice from programmers often hurts as much as it helps.
1242 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
1243 this change shrinks the text size of the Emacs executable by 1.1%
1244 without affecting CPU significantly in my benchmark.
1245 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)

1325 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
1327 Revert the FOLLOW-SYMLINKS change for file-attributes.
1328 Doing it right would require several changes to Tramp, and there's
1329 not enough time to get that tested before the freeze today.
1330 * dired.c (directory_files_internal, Ffile_attributes):
1333 * frame.c (x_report_frame_params): Port better to wider ints.
1334 Do not assume that EMACS_UINT is the same width as uprintmax_t,
1335 or that pointers can be printed in 15 decimal digits.
1336 Avoid GCC warnings if EMACS_UINT is wider than a pointer.

1372 * vm-limit.c (lim_data): Now size_t.
1373 (check_memory_limits): Adjust prototypes of real_morecore and
1374 __morecore to receive argument of type ptrdiff_t. Use size_t for

1454 * xdisp.c (start_hourglass, cancel_hourglass): Now used on
1456 (start_hourglass) [WINDOWSNT]: Call w32_note_current_window.
1458 * w32.h (init_timers, term_timers): Add prototypes.
1460 2012-09-30 Kenichi Handa <handa@gnu.org>

1499 (EmacsFSWindow): New interface for fullscreen.
1501 2012-09-30 Juanma Barranquero <lekktu@gmail.com>
1503 * makefile.w32-in ($(BLD)/profiler.$(O)): Update dependencies.
1505 2012-09-30 Chong Yidong <cyd@gnu.org>
1507 * fns.c (Frandom): Doc fix.
1509 2012-09-30 Martin Rudalics <rudalics@gmx.at>

1512 (Qwindow_size): New symbol replacing Qtemp_buffer_resize.
1514 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
1516 * syssignal.h (PROFILER_CPU_SUPPORT): Don't define if PROFILING.
1517 Suggested by Eli Zaretskii in
1518 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00811.html>.
1520 2012-09-30 Eli Zaretskii <eliz@gnu.org>
1522 * profiler.c (Fprofiler_cpu_stop): Use timer_settime only if
1523 HAVE_TIMER_SETTIME is defined.
1525 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
1527 Profiler improvements: more-accurate timers, overflow checks.
1528 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
1529 signal.h, setjmp.h. Include systime.h instead.
1530 (saturated_add): New function.
1531 (record_backtrace, current_sample_interval): Use EMACS_INT, not size_t.
1532 (record_backtrace, handle_profiler_signal): Saturate on fixnum overflow.
1533 (profiler_timer, profiler_timer_ok) [HAVE_TIMER_SETTIME]:
1535 (enum profiler_cpu_running): New enum.
1536 (profiler_cpu_running): Now of that enum type, not bool.
1537 All uses changed to store the new value.
1538 (handle_profiler_signal): Rename from sigprof_handler_1,
1539 for consistency with other handlers. Do not check whether
1540 cpu_log is a hash-table if garbage collecting, since it
1541 doesn't matter in that case.
1542 (deliver_profiler_signal): Rename from sigprof_handler,
1543 for consistency with other handlers.
1544 (setup_cpu_timer): New function, with much of what used to be in
1545 Fprofiler_cpu_start. Check for out-of-range argument.
1546 Prefer timer_settime if available, and prefer
1547 thread cputime clocks, then process cputime clocks, then
1548 monotonic clocks, to the old realtime clock. Use make_timeval
1549 to round more-correctly when falling back to setitimer.
1550 (Fprofiler_cpu_start): Use it.
1551 (Fprofiler_cpu_stop): Prefer timer_settime if available.
1552 Don't assume that passing NULL as the 2nd argument of setitimer
1553 is the same as passing a pointer to all-zero storage.
1554 Ignore SIGPROF afterwards.
1555 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
1556 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
1557 non-fatal signal handlers. Ignore SIGPROF on startup.
1558 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
1559 in profiler.c, since sysdep.c now uses it.
1561 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.
1562 Suggested by Eli Zaretskii in
1563 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.

1585 * xdisp.c (syms_of_xdisp) <Qredisplay_internal>: Rename from
1586 Qautomatic_redisplay and change the symbol name. All users changed.

1615 * character.h (MAYBE_UNIFY_CHAR): Remove.
1616 * charset.c, charset.h (maybe_unify_char): Now static.
1617 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
1618 Since this stuff is now private to charset.c, there's no need for
1619 a public macro and no need to inline by hand.

1652 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>
1654 Prefer POSIX timers if available.
1655 They avoid a race if the timer is too close to the current time.
1656 * atimer.c (alarm_timer, alarm_timer_ok) [SIGEV_SIGNAL]: New static vars.
1657 (set_alarm) [SIGEV_SIGNAL]: Use POSIX timers if available.

1683 * w32.h (Vlibrary_cache): Do not declare.
1685 2012-09-25 Eli Zaretskii <eliz@gnu.org>
1687 * w32proc.c (sys_signal): Handle all signals defined by the
1688 MS-Windows runtime, not just SIGCHLD. Actually install the signal
1689 handlers for signals supported by Windows. Don't override
1690 term_ntproc as the handler for SIGABRT.
1691 (sigaction): Rewrite to call sys_signal instead of duplicating its
1693 (sys_kill): Improve commentary.
1695 * w32.c (term_ntproc): Accept (and ignore) one argument, for
1696 consistency with a signature of a signal handler. All callers
1698 (init_ntproc): Accept an argument DUMPING. If dumping, don't
1699 install term_ntproc as a signal handler for SIGABRT, as that
1700 should be done by the dumped Emacs.
1702 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
1704 * w32select.c (term_w32select): Protect against repeated
1705 invocation by setting clipboard_owner to NULL after calling
1708 * emacs.c (shut_down_emacs, main): Adapt the calls to init_ntproc
1709 and term_ntproc to their modified signatures.
1711 * character.c (char_string, string_char): Remove calls to

1723 when encountering an unknown bytecode.
1725 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
1727 image.c, indent.c: Use bool for booleans.

1730 * image.c: Omit unnecessary static decls.
1731 (x_create_bitmap_mask, x_build_heuristic_mask):

1770 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
1771 (interruptible_wait_for_termination):
1772 Move these decls from lisp.h to syswait.h, since they use pid_t.
1773 Needed on FreeBSD; see Herbert J. Skuhra in
1774 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.

1821 2012-09-23 Eli Zaretskii <eliz@gnu.org>
1823 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
1824 fatal_error_backtrace.
1826 * w32proc.c (sys_kill): Undo last change: don't do anything when
1827 invoked to deliver SIGABRT to our own process. This is now
1828 handled by emacs_raise.
1830 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
1832 * w32term.c (w32_read_socket): Remove leftover reference to
1833 interrupt_input_pending.
1835 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
1837 Do not use SA_NODEFER.
1838 Problem reported by Dani Moncayo in
1839 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
1841 * sysdep.c (emacs_abort): Do not reset signal handler.
1842 * emacs.c (terminate_due_to_signal): Reset signal handler here.
1843 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
1844 wanted even on POSIXish hosts, and it doesn't work on Windows.
1846 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
1848 * xterm.c (x_term_init): Call fixup_locale before and after calling
1849 gtk_init (Bug#12392).
1851 2012-09-23 Chong Yidong <cyd@gnu.org>
1853 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
1854 Vdynamic_library_alist.
1856 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
1857 (Fgnutls_available_p): Caller changed.
1859 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
1860 (Flibxml_parse_xml_region): Likewise.
1862 * dispextern.h (struct image_type): Remove arg from init function.
1864 * image.c (Finit_image_library, lookup_image_type)
1865 (define_image_type): Remove now-unneeded second arg.
1866 (init_xpm_functions, init_png_functions, init_jpeg_functions)
1867 (init_tiff_functions, init_gif_functions, init_svg_functions):
1868 Arglist and w32_delayed_load calling convention changed.
1869 (gs_type): Remove init_gs_functions; there is no such function.
1870 (valid_image_p, make_image): Fix caller to lookup_image_type.
1872 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
1874 Simplify and avoid signal-handling races (Bug#12471).
1876 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
1877 Avoid recursive loop if there's a fatal error in the function itself.
1878 * atimer.c (pending_atimers):
1879 * blockinput.h: Don't include "atimer.h"; no longer needed.
1880 (interrupt_input_pending): Remove. All uses removed.
1881 pending_signals now counts both atimers and ordinary interrupts.
1882 This is less racy than having three separate pending-signal flags.
1883 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
1885 Rename from their upper-case counterparts BLOCK_INPUT,
1886 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
1887 INPUT_BLOCKED_P, and turn into functions. All uses changed.
1888 This makes it easier to access volatile variables more accurately.
1889 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
1890 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
1891 that's more reliable if the code is buggy and sets
1892 interrupt_input_blocked to a negative value. All uses changed.
1893 * atimer.c (deliver_alarm_signal):
1894 Remove. No need to deliver this to the parent; any thread can
1895 handle this signal now. All uses replaced by underlying handler.
1896 * atimer.c (turn_on_atimers):
1897 * dispnew.c (handle_window_change_signal):
1898 * emacs.c (handle_danger_signal):
1899 * keyboard.c (kbd_buffer_get_event):
1900 Don't reestablish signal handler; not needed with sigaction.
1901 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
1903 Rework to avoid unnecessary accesses to volatile variables.
1904 (UNBLOCK_INPUT_TO): Now a function.
1905 (totally_unblock_input, unblock_input): New decls.
1906 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
1907 (init_data): Remove. Necessary stuff now done in init_signal.
1908 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
1909 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
1910 (fatal_error_code): Remove; no longer needed.
1911 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
1912 it doesn't always backtrace. All uses changed. No need to reset
1913 signal to default, since sigaction and/or die does that for us now.
1914 Use emacs_raise (FOO), not kill (getpid (), FOO).
1915 (main): Check more-accurately whether we're dumping.
1916 Move fatal-error setup to sysdep.c
1917 * floatfns.c: Do not include "syssignal.h"; no longer needed.
1918 * gtkutil.c (xg_get_file_name, xg_get_font):
1919 Remove no-longer-needed signal-mask manipulation.
1920 * keyboard.c, process.c (POLL_FOR_INPUT):
1921 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
1922 * keyboard.c (read_avail_input): Remove.
1923 All uses replaced by gobble_input.
1924 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
1925 (kbd_buffer_store_event_hold, gobble_input):
1926 (record_asynch_buffer_change) [USABLE_SIGIO]:
1927 (store_user_signal_events):
1928 No need to mess with signal mask.
1929 (gobble_input): If blocking input and there are terminals, simply
1930 set pending_signals to 1 and return. All hooks changed to not
1931 worry about whether input is blocked.
1932 (process_pending_signals): Clear pending_signals before processing
1933 them, in case a signal comes in while we're processing.
1934 By convention callers now test pending_signals before calling us.
1935 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
1936 New functions, to support changes to blockinput.h.
1937 (handle_input_available_signal): Now extern.
1938 (reinvoke_input_signal): Remove. All uses replaced by
1940 (quit_count): Now volatile, since a signal handler uses it.
1941 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
1942 All callers changed. Block SIGINT only if not already blocked.
1943 Clear sigmask reliably, even if Fsignal returns, which it can.
1944 Omit unnecessary accesses to volatile var.
1945 (quit_throw_to_read_char): No need to restore sigmask.
1946 * keyboard.c (gobble_input, handle_user_signal):
1947 * process.c (wait_reading_process_output):
1948 Call signal-handling code rather than killing ourselves.
1949 * lisp.h: Include <float.h>, for...
1950 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
1951 (pending_signals): Now volatile.
1952 (syms_of_data): Now const if IEEE floating point.
1953 (handle_input_available_signal) [USABLE_SIGIO]:
1954 (terminate_due_to_signal, record_child_status_change): New decls.
1955 * process.c (create_process): Avoid disaster if memory is exhausted
1956 while we're processing a vfork, by tightening the critical section
1958 (send_process_frame, process_sent_to, handle_pipe_signal)
1959 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
1961 (send_process): No need for setjmp/longjmp any more, since the
1962 SIGPIPE stuff is now gone. Instead, report an error if errno
1964 (record_child_status_change): Now extern. PID and W are now args.
1965 Return void, not bool. All callers changed.
1966 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
1967 Remove. All uses removed. This bug should be fixed now in a
1969 (wait_for_termination_1): Use waitpid rather than sigsuspend,
1970 and record the child status change directly. This avoids the
1971 need to futz with the signal mask.
1972 (process_fatal_action): Move here from emacs.c.
1973 (emacs_sigaction_flags): New function, containing
1974 much of what used to be in emacs_sigaction_init.
1975 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
1976 caught by emacs, to make races less likely.
1977 (deliver_process_signal): Rename from handle_on_main_thread.
1979 (BACKTRACE_LIMIT_MAX): Now at top level.
1980 (thread_backtrace_buffer, threadback_backtrace_pointers):
1982 (deliver_thread_signal, deliver_fatal_thread_signal):
1983 New functions, for more-accurate delivery of thread-specific signals.
1984 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
1985 (deliver_arith_signal): Handle in this thread, not
1986 in the main thread, since it's triggered by this thread.
1987 (maybe_fatal_sig): New function.
1988 (init_signals): New arg DUMPING so that we can be more accurate
1989 about whether we're dumping. Caller changed.
1990 Treat thread-specific signals differently from process-general signals.
1991 Block all signals while handling fatal error; that's safer.
1992 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
1994 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
1995 Ignore SIGPIPE unless batch.
1996 (emacs_backtrace): Output backtrace for the appropriate thread,
1997 which is not necessarily the main thread.
1998 * syssignal.h: Include <stdbool.h>.
1999 (emacs_raise): New macro.
2000 * xterm.c (x_connection_signal): Remove; no longer needed
2001 now that we use sigaction.
2002 (x_connection_closed): No need to mess with sigmask now.
2003 (x_initialize): No need to reset SIGPIPE handler here, since
2004 init_signals does this for us now.
2006 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
2008 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
2009 background rect may be larger (Bug#12245).
2011 2012-09-23 Chong Yidong <cyd@gnu.org>
2013 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
2015 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
2017 * .gdbinit: Just stop at fatal_error_backtrace.
2018 See Stefan Monnier's request in
2019 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
2020 Remove no-longer-used query of system type.
2022 2012-09-22 Chong Yidong <cyd@gnu.org>
2024 * search.c (Freplace_match): Doc fix (Bug#12325).
2026 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
2028 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
2029 (Fline_end_position): Doc fix.
2031 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
2033 2012-09-22 Chong Yidong <cyd@gnu.org>
2035 * dispextern.h (struct image_type): Add new slot, storing a type
2036 initialization function.
2038 * image.c (define_image_type): Call the image initializer function
2039 if it is defined. Arguments and return value changed.
2040 (valid_image_p, make_image): Callers changed.
2041 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
2042 (gif_type, imagemagick_type, svg_type, gs_type):
2043 Add initialization functions.
2044 (Finit_image_library): Call lookup_image_type.
2045 (CHECK_LIB_AVAILABLE): Macro deleted.
2046 (lookup_image_type): Call define_image_type here, rather than via
2047 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
2048 (syms_of_image): Move define_image_type calls for xbm_type and
2049 pbm_type to lookup_image_type.
2051 2012-09-22 Eli Zaretskii <eliz@gnu.org>
2053 * keyboard.c (timer_check_2): Move calculation of 'timers' and
2054 'idle_timers' from here ...
2055 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
2056 lists, to avoid infloops when the timer does something stupid,
2057 like reinvoke itself with the same or smaller time-out.
2060 2012-09-22 Martin Rudalics <rudalics@gmx.at>
2062 * window.c (Fsplit_window_internal): Handle only Qt value of
2063 Vwindow_combination_limit separately.
2064 (Qtemp_buffer_resize): New symbol.
2065 (Vwindow_combination_limit): New default value.
2068 2012-09-22 Eli Zaretskii <eliz@gnu.org>
2070 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
2071 the new overlay string. (Bug#10159)
2073 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
2075 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
2076 or that fprintf is async-signal-safe. POSIX doesn't require
2079 2012-09-22 Chong Yidong <cyd@gnu.org>
2081 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
2084 2012-09-22 Kenichi Handa <handa@gnu.org>
2086 * composite.c (composition_reseat_it): Handle the case that a
2087 grapheme cluster is not covered by a single font (Bug#12352).
2089 2012-09-21 Chong Yidong <cyd@gnu.org>
2091 * image.c (define_image_type): Avoid adding duplicate types to
2092 image_types (Bug#12463). Suggested by Jörg Walter.
2094 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2096 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
2097 (print_load_command_name): Add case LC_DATA_IN_CODE.
2098 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
2100 2012-09-21 Glenn Morris <rgm@gnu.org>
2102 * eval.c (Frun_hook_with_args_until_success)
2103 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
2105 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
2107 * fileio.c (Ffile_selinux_context): Only call freecon when
2108 lgetfilecon succeeded.
2109 (Fset_file_selinux_context): Likewise. (Bug#12444)
2111 2012-09-21 Eli Zaretskii <eliz@gnu.org>
2113 * xdisp.c (try_window_reusing_current_matrix): Under bidi
2114 reordering, locate the cursor by calling set_cursor_from_row; if
2115 that fails, clear the desired glyph matrix before returning a
2116 failure indication to the caller. Fixes leaving garbled display
2117 when fast scrolling with a down-key. (Bug#12403)
2118 (compute_stop_pos_backwards): Fix a typo that caused crashes while
2119 scrolling through multibyte text.
2121 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
2123 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
2124 calling mark_vectorlike since that's the one that marks the window.
2125 (mark_discard_killed_buffers): Mark the final cdr.
2126 * window.h (struct window): Move prev/next_buffers to the
2127 non-standard fields.
2128 * window.c (make_window): Initialize prev/next_buffers manually.
2130 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
2132 Omit unused arg EXPECTED from socket hooks.
2133 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
2134 * nsterm.m (ns_term_init):
2135 * termhooks.h (struct terminal.read_socket_hook):
2136 * w32inevt.c (w32_console_read_socket):
2137 * w32term.c (w32_read_socket):
2138 * xterm.c (XTread_socket):
2139 Omit unused arg EXPECTED. All callers changed.
2140 (store_user_signal_events): Return void, not int, since callers no
2141 longer care about the return value. All uses changed.
2143 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
2145 * w32gui.h (XParseGeometry): Do not declare.
2147 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
2149 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
2150 Ignore 'expected'. See Eli Zaretskii in
2151 <http://bugs.gnu.org/12471#8> (last line).
2153 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
2154 (XParseGeometry): Now static. Substitute extremal values for
2155 values that are out of range.
2157 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
2159 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
2161 * nsfns.m (XParseGeometry): Remove.
2162 (Fx_create_frame): Call x_set_offset to correctly interpret
2163 top_pos in geometry.
2165 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
2166 (Fx_parse_geometry): If there is a space in string, call
2167 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
2169 2012-09-17 Eli Zaretskii <eliz@gnu.org>
2171 * search.c (scan_buffer): Use character positions in calls to
2172 region_cache_forward and region_cache_backward, not byte
2173 positions. (Bug#12196)
2175 * w32term.c (w32_read_socket): Set pending_signals to 1, like
2176 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
2178 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
2179 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
2180 emacs_blocked_malloc, now deleted.
2182 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
2184 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
2185 The workaround was for improving performance on Solaris 2.4, but
2186 is getting in the way now. Emacs will still work if someone is
2187 still running Solaris 2.4 in a museum somewhere; Sun dropped
2188 support for Solaris 2.4 in 2003.
2189 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
2190 * process.c (create_process) [HAVE_WORKING_VFORK]:
2191 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
2192 since Emacs no longer uses vfork on that platform.
2194 2012-09-17 Glenn Morris <rgm@gnu.org>
2196 * emacs.c: Use COPYRIGHT.
2198 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
2200 Remove configure's --without-sync-input option (Bug#12450).
2201 When auditing signal-handling in preparation for cleaning it up,
2202 I found that SYNC_INPUT has race conditions and would be a real
2203 pain to fix. Since it's an undocumented and deprecated
2204 configure-time option, now seems like a good time to remove it.
2205 Also see <http://bugs.gnu.org/11080#16>.
2206 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
2207 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
2208 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
2209 (malloc_hysteresis):
2210 (check_depth) [XMALLOC_OVERRUN_CHECK]:
2211 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
2212 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
2213 (dont_register_blocks, bytes_used_when_reconsidered)
2214 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
2215 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
2216 [!SYSTEM_MALLOC && !SYNC_INPUT]:
2217 Remove. All uses removed.
2218 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
2219 implementation, one that depends on whether the new macro
2220 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
2222 * atimer.c (run_timers, handle_alarm_signal):
2223 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
2224 (handle_async_input, process_pending_signals)
2225 (handle_input_available_signal, init_keyboard):
2226 * nsterm.m (ns_read_socket):
2227 * process.c (wait_reading_process_output):
2228 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
2229 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
2231 * xterm.c (XTread_socket):
2233 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
2234 * eval.c (handling_signal): Remove. All uses removed.
2235 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
2236 All uses replaced with the SYNC_INPUT version.
2237 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
2239 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
2242 * font.c (Ffont_shape_gstring): Remove unused local.
2244 2012-09-16 Glenn Morris <rgm@gnu.org>
2246 * Makefile.in (clean): No longer run nextstep's clean.
2248 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
2250 (ns-app): Move here from ns.mk, and simplify.
2251 (clean): Simplify nextstep entry.
2252 * ns.mk: Remove file.
2254 2012-09-17 Kenichi Handa <handa@gnu.org>
2256 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
2257 not covert the last few charactes.
2259 2012-09-16 Kenichi Handa <handa@gnu.org>
2261 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
2262 here, but just check the validity of glyphs in the glyph-string.
2264 2012-09-16 Martin Rudalics <rudalics@gmx.at>
2266 * window.c (Fwindow_parameter, Fset_window_parameter):
2267 Accept any window as argument (Bug#12452).
2269 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
2271 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
2272 to ns_term_init to avoid memory leak.
2274 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
2275 explicit retain/release.
2276 (ns_term_init): Only allow one display. Initialize outerpool and
2279 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
2281 Port _setjmp fix to POSIXish hosts as well as Microsoft.
2282 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
2283 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
2284 the Microsoft problem in a different way, by altering ../nt/config.nt.
2286 2012-09-15 Eli Zaretskii <eliz@gnu.org>
2301 * w16select.c: Remove inclusion of setjmp.h, as it is now included
2302 by lisp.h. This completes removal of setjmp.h inclusion
2303 erroneously announced in the previous commit. (Bug#12446)
2305 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
2308 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
2309 not defined as a macro. The latter happens on MS-Windows.
2312 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
2314 Port better to POSIX hosts lacking _setjmp (Bug#12446).
2315 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
2316 Some instances of '#include <setjmp.h>' removed, if the
2317 only reason for the instance was because "lisp.h" was included.
2318 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
2319 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
2320 and _longjmp with the new symbols. Emacs already uses _setjmp if
2321 available, so this change affects only POSIXish hosts that have
2322 sigsetjmp but not _setjmp, such as some versions of Solaris and
2323 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
2324 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
2325 (png_load_body) [HAVE_PNG]:
2326 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
2327 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
2328 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
2329 since PNG requires jmp_buf. This is the only exception to the
2330 general rule that we now use sys_setjmp and sys_longjmp.
2331 This exception is OK since this code does not change the signal
2332 mask or longjmp out of a signal handler.
2334 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
2336 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
2337 Include "syssignal.h", for 'main_thread'.
2339 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
2341 Avoid out-of-range marker position (Bug#12426).
2342 * insdel.c (replace_range, replace_range_2):
2343 Adjust markers before overlays, as suggested by comments.
2344 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
2345 Remove redundant check before calling offset_intervals.
2347 2012-09-14 Martin Rudalics <rudalics@gmx.at>
2349 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
2350 current buffer (Bug#12387).
2352 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
2354 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
2356 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
2358 Use a more backwards-compatible timer format (Bug#12430).
2359 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
2360 vector element, not from the 4th, since PSECS is now at the end.
2361 (Fcurrent_idle_time): Doc fix.
2363 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
2365 Function to mark objects and remove killed buffers at once.
2366 * alloc.c (discard_killed_buffers): Rename to ...
2367 (mark_discard_killed buffers) ... new name. Add marking
2368 of remaining objects. Fix comment. Adjust users.
2369 (mark_object): Do not touch frame buffer lists here.
2370 * frame.c (delete_frame): Reset frame buffer lists here.
2372 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
2374 Better workaround for GNOME bug when --enable-gcc-warnings.
2375 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
2376 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
2377 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
2379 Simplify SIGIO usage (Bug#12408).
2380 The code that dealt with SIGIO was crufty and confusing, e.g., it
2381 played tricks like "#undef SIGIO" but these tricks were not used
2382 consistently. Simplify mostly by not #undeffing standard symbols,
2383 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
2384 or not as we please) rather than "defined SIGIO" (standard symbol
2385 that we probably shouldn't #undef).
2386 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
2387 Modules that need it can include it.
2388 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
2389 * dispextern.h (ignore_sigio): New decl.
2390 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
2391 unconditionally, since it's now a no-op if !USABLE_SIGIO.
2392 * emacs.c (shut_down_emacs):
2393 * keyboard.c (kbd_buffer_store_event_hold):
2394 Use ignore_sigio rather than invoking 'signal' directly.
2395 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
2397 (FIONREAD, SIGIO): Do not #undef.
2398 (tty_read_avail_input): Use #error rather than a syntax error.
2399 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
2400 for I_PIPE, used by SETUP_SLAVE_PTY.
2401 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
2402 * sysdep.c (croak): Remove; no longer needed. This bit of
2403 temporary code, with Fred N. Fish's comment that it's temporary,
2404 has been in Emacs since at least 1992!
2405 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
2406 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
2407 * syssignal.h (croak): Remove decl.
2408 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
2409 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
2410 now that we're termios-only.
2411 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
2412 * term.c (dissociate_if_controlling_tty): Use #error rather than
2415 Work around GCC and GNOME bugs when --enable-gcc-warnings.
2416 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
2417 to work around GNOME bug 683906.
2418 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
2419 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
2420 This works around GCC bug 54561.
2422 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
2424 More fixes for 'volatile' and setjmp/longjmp.
2425 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
2426 * image.c (struct png_load_context) [HAVE_PNG]: New type.
2427 (png_load_body) [HAVE_PNG]:
2428 (jpeg_load_body) [HAVE_JPEG]:
2429 New function, with most of the old parent function's body.
2430 (png_load) [HAVE_PNG]:
2431 (jpeg_load) [HAVE_JPEG]:
2432 Invoke the new function, to avoid longjmp munging our locals.
2433 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
2434 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
2435 longjmp is passed 2, as the C standard doesn't guarantee this.
2436 Instead, store the failure code into mgr->failure_code.
2438 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
2440 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
2441 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
2442 (syms_of_keyboard): Remove support for unread-command-char.
2444 2012-09-12 Eli Zaretskii <eliz@gnu.org>
2446 * w32proc.c (sys_kill): If PID is our process ID and the signal is
2447 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
2448 violation. (Bug#12426)
2450 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
2452 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
2454 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
2456 * eval.c: Add `inhibit-debugger'.
2457 (Qinhibit_debugger): New symbol.
2458 (call_debugger): Bind it instead of Qdebug_on_error.
2459 (maybe_call_debugger): Test Vinhibit_debugger.
2460 (syms_of_eval): Define inhibit-debugger.
2461 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
2462 (syms_of_xdisp): Remove inhibit-debug-on-message.
2464 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
2466 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
2467 If a nonvolatile local variable is written before a _longjmp to
2468 the frame containing the variable, and is read after the _longjmp,
2469 the value read is indeterminate. Some local variables of type
2470 'struct handler' and 'struct catchtag' are used in this way, so
2471 mark each of their slots as volatile if the slot can be set before
2472 _longjmp and read afterwards.
2473 * lisp.h (struct handler): var and chosen_clause are now volatile.
2474 (struct catchtag): val, next, and pdlcount are now volatile.
2476 * bidi.c (bidi_push_it, bidi_pop_it):
2477 * fns.c (copy_hash_table):
2478 * image.c (define_image_type):
2479 * keyboard.c (kbd_buffer_store_event_hold):
2480 * process.c (Fprocess_send_eof):
2481 * xfaces.c (x_create_gc) [HAVE_NS]:
2482 * xgselect.c (xg_select):
2483 Prefer assignment to memcpy when either will do.
2485 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
2486 Use pointer-to-a-pointer to simplify and avoid a NILP check each
2487 time an item is removed. No need to mark this function 'inline';
2488 the compiler knows better than we do.
2490 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
2492 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
2493 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
2494 to change_frame_size (Bug#12388).
2495 (windowDidResize:): Pass YES to updateFrameSize.
2497 * nsterm.h: Add delay parameter to updateFrameSize.
2499 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
2501 Discard killed buffers from deleted window and frame objects.
2502 This reduces an amount of references to killed buffers and
2503 helps GC to reclaim them faster.
2504 * alloc.c (discard_killed_buffers): New function.
2505 (mark_object): Use it for deleted windows and frames.
2506 (mark_object): If symbol's value is set up for a killed buffer
2507 or deleted frame, restore its global binding.
2508 * data.c (swap_in_global_binding): Add GC notice.
2509 (swap_in_symval_forwarding): Use convenient set_blv_where.
2510 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
2511 * window.h: ... to here.
2513 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
2515 Convenient macro to check whether the buffer is live.
2516 * buffer.h (BUFFER_LIVE_P): New macro.
2517 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
2518 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
2520 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2522 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
2523 composition cases (Bug#12364).
2525 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
2526 overhang of succeeding glyphs overlapping box cursor.
2528 * w32term.c (x_draw_glyph_string): Likewise.
2530 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
2532 Simplify, document, and port floating-point (Bug#12381).
2533 The porting part of this patch fixes bugs on non-IEEE platforms
2534 with frexp, ldexp, logb.
2535 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
2537 * floatfns.c: Simplify discussion of functions that Emacs doesn't
2538 support, by removing commented-out code and briefly listing the
2539 C89 functions excluded. The commented-out stuff was confusing
2540 maintenance, e.g., we thought we needed cbrt but it was commented out.
2541 (logb): Remove decl; no longer needed.
2542 (isfinite): New macro, if not already supplied.
2543 (isnan): Don't replace any existing macro.
2544 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
2545 are present on all C89 platforms.
2546 (Ffrexp): Do not special-case zero, as frexp does the right thing
2548 (Flogb): Do not use logb, as it doesn't have the desired meaning
2549 on hosts that use non-base-2 floating point. Instead, stick with
2550 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
2551 frexp, to avoid getting an unspecified result.
2553 * xdisp.c (Qinhibit_debug_on_message): Now static.
2555 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
2557 * nsterm.m (ns_update_begin): Set clip path to whole view by using
2558 NSBezierPath (Bug#12131).
2560 2012-09-10 Chong Yidong <cyd@gnu.org>
2562 * fns.c (Fdelq, Fdelete): Doc fix.
2564 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
2566 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
2567 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
2569 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
2571 * lisp.h (make_lisp_ptr): New macro to replace XSET.
2572 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
2575 2012-09-09 Eli Zaretskii <eliz@gnu.org>
2577 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
2578 left fringe if the window has a left margin. This avoids leaving
2579 traces of the cursor because its leftmost pixel is not drawn over.
2581 * dispnew.c (update_window_line): When the left margin area of a
2582 screen line is updated, set the redraw_fringe_bitmaps_p flag of
2583 that screen line. (Bug#12277)
2585 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
2587 Assume C89 or later for math functions (Bug#12381).
2588 This simplifies the code, and makes it a bit smaller and faster,
2589 and (most important) makes it easier to clean up signal handling
2590 since we can stop worring about floating-point exceptions in
2591 library code. That was a problem before C89, but the problem
2592 went away many years ago on all practical Emacs targets.
2593 * data.c, image.c, lread.c, print.c:
2594 Don't include <math.h>; no longer needed.
2595 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
2596 might be autoconfigured, as that never happens.
2598 * doprnt.c (DBL_MAX_10_EXP):
2599 * print.c (DBL_DIG):
2600 Remove. C89 or later always defines these.
2601 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
2602 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
2603 (arith_error, domain_error, domain_error2):
2604 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
2605 no longer needed -- we simply return what C returns. All uses removed.
2606 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
2608 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
2609 Remove. All uses expanded, as these macros are no longer used
2610 more than once and are now more trouble than they're worth.
2611 (Ftan): Use tan, not sin / cos.
2612 (Flogb): Assume C89 frexp.
2613 (fmod_float): Assume C89 fmod.
2614 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
2615 (init_floatfns): Remove. All uses removed.
2617 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
2619 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
2620 compositeToPoint for OSX < 10.6 (Bug#12390).
2622 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
2624 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
2625 This produces more-accurate results.
2627 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
2629 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
2630 changes (Bug#12088).
2632 2012-09-08 Chong Yidong <cyd@gnu.org>
2634 * syntax.c (Fstring_to_syntax): Doc fix.
2636 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
2638 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
2639 in the internal border.
2640 (x_set_window_size): Remove static variables and their usage.
2641 (ns_redraw_scroll_bars): Fix NSTRACE arg.
2642 (ns_after_update_window_line, ns_draw_fringe_bitmap):
2643 Remove fringe/internal border adjustment (Bug#11052).
2644 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
2645 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
2646 (ns_fix_rect_ibw): Remove.
2647 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
2648 (ns_dumpglyphs_box_or_relief): Ditto.
2649 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
2651 (ns_dumpglyphs_image): Ditto.
2652 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
2654 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
2655 their usage. Add fringe_extended_p and its use as in other terms.
2656 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
2657 scroll bar was removed.
2658 (updateFrameSize): New function.
2659 (windowDidResize): Move code to updateFrameSize and call it.
2661 * nsterm.h (EmacsView): Add updateFrameSize.
2663 2012-09-07 Chong Yidong <cyd@gnu.org>
2665 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
2667 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
2669 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
2671 More signal-handler cleanup (Bug#12327).
2672 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
2673 Problem introduced when merging patches. Noted by Eli Zaretskii in
2674 <http://bugs.gnu.org/12327#67>.
2675 * floatfns.c: Comment fix.
2676 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
2677 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
2678 and anyway the declaration is harmless even if SIGDANGER is not defined.
2679 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
2680 defined BROKEN_FIONREAD). systty.h formerly did this, but other
2681 source files not surprisingly expected syssignal.h to define, or
2682 not define, SIGIO, and it's cleaner to do it that way, for consistency.
2683 Include <sys/ioctl.h>, for FIONREAD.
2684 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
2685 This eliminates a problem whereby other files mysteriously had
2686 to include "syssignal.h" before including "systty.h" if they
2687 wanted to use "#ifdef SIGIO".
2689 2012-09-07 Eli Zaretskii <eliz@gnu.org>
2691 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
2693 * w32.c (sigemptyset): Empty the set.
2694 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
2696 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
2698 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
2700 * alloc.c (mark_buffer): Revert unsafe marking optimization.
2701 (mark_object): Likewise for frame objects.
2703 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
2705 * syssignal.h (handle_on_main_thread): Always declare,
2706 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
2707 This ports to platforms without HAVE_PTHREAD.
2709 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
2711 Signal-handler cleanup (Bug#12327).
2712 Emacs's signal handlers were written in the old 4.2BSD style with
2713 sigblock and sigmask and so forth, and this led to some
2714 inefficiencies and confusion. Rewrite these to use
2715 pthread_sigmask etc. without copying signal sets around. Also,
2716 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
2717 'signal', and instead use functions that do not attempt to take
2718 over the system name space. This patch causes Emacs's text
2719 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
2720 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
2721 Do not include <signal.h> or "syssignal.h", as these
2722 modules do not use signals.
2723 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
2724 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
2725 Do not include <signal.h>, as "syssignal.h" does that for us now.
2726 * atimer.c (sigmask_atimers): New function.
2727 (block_atimers, unblock_atimers): New functions,
2728 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
2730 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
2731 no longer needed here.
2732 * emacs.c (main): Inspect existing signal handler with sigaction,
2733 so that there's no need to block and unblock SIGHUP.
2734 * sysdep.c (struct save_signal): New member 'action', replacing
2735 old member 'handler'.
2736 (save_signal_handlers, restore_signal_handlers):
2737 Use sigaction instead of 'signal' to save and restore.
2738 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
2739 New function. All users of 'signal' modified to use set_sighandler
2740 if they're writeonly, and to use sys_signal if they're read+write.
2741 (emacs_sigaction_init, forwarded_signal): New functions.
2742 (sys_signal): Remove. All uses replaced by calls to sigaction
2743 and emacs_sigaction_init, or by direct calls to 'signal'.
2744 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
2745 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
2746 all uses replaced by pthread_sigmask etc. calls.
2747 * syssignal.h: Include <signal.h>.
2748 (emacs_sigaction_init, forwarded_signal): New decls.
2749 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
2750 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
2751 (sigmask, sys_sigmask): Remove; no longer needed.
2752 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
2753 (sigblock, sigunblock, sigfree):
2754 (sigsetmask) [!defined sigsetmask]:
2755 Remove. All uses replaced by pthread_sigmask.
2756 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
2757 no longer need to be replaced, and its typical old uses
2758 are now done via emacs_sigaction_init and sigaction.
2759 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
2760 (sys_sigdel): Remove; unused.
2761 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
2763 2012-09-06 Eli Zaretskii <eliz@gnu.org>
2765 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
2766 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
2768 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
2770 Explicitly mark buffer_defaults and buffer_local_symbols.
2771 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
2772 mark_local_symbols here.
2773 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
2774 since special buffers aren't marked here any more.
2775 (allocate_buffer): Chain new buffer with all_buffers here...
2776 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
2778 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
2779 (syms_of_buffer): Remove staticpro of the above.
2780 (init_buffer_once): Set names for buffer_defaults and
2781 buffer_local_symbols.
2783 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
2785 Use bool for booleans in font-related modules.
2786 * font.c (font_intern_prop, font_style_to_value)

2791 (fontset_find_font, Fset_fontset_font)
2792 (face_suitable_for_char_p) [0]:
2793 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
2794 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
2795 (m17n_flt_initialized, ftfont_shape_by_flt):
2796 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
2797 * nsfont.m (nsfont_draw):
2798 * w32font.c (w32font_draw):
2799 * w32term.c (x_draw_glyphless_glyph_string_foreground):
2800 Use bool for booleans.
2801 * font.h: Adjust to above API changes.
2802 (struct font, struct font_driver, struct font_driver_list):
2803 Use bool for booleans.
2804 (struct font): Remove useless member encoding_type.
2806 * fontset.c, xftfont.c: Omit unnecessary static decls.
2808 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
2810 * alloc.c (mark_object): Revert window marking code
2811 since it's unsafe for the Fset_window_configuration.
2813 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
2815 Fix race conditions with signal handlers and errno (Bug#12327).
2816 Be more systematic about preserving errno whenever a signal
2817 handler returns, even if it's not in the main thread. Do this by
2818 renaming signal handlers to distinguish between signal delivery
2819 and signal handling. All uses changed.
2820 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
2821 * data.c (deliver_arith_signal): Rename from arith_error.
2822 * dispnew.c (deliver_window_change_signal): Rename from
2823 window_change_signal.
2824 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
2825 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
2826 * keyboard.c (deliver_input_available_signal): Rename from
2827 input_available_signal.
2828 (deliver_user_signal): Rename from handle_user_signal.
2829 (deliver_interrupt_signal): Rename from interrupt_signal.
2830 * process.c (deliver_pipe_signal): Rename from send_process_trap.
2831 (deliver_child_signal): Rename from sigchld_handler.
2832 * atimer.c (handle_alarm_signal):
2833 * data.c (handle_arith_signal):
2834 * dispnew.c (handle_window_change_signal):
2835 * emacs.c (handle_fatal_signal, handle_danger_signal):
2836 * keyboard.c (handle_input_available_signal):
2837 * keyboard.c (handle_user_signal, handle_interrupt_signal):
2838 * process.c (handle_pipe_signal, handle_child_signal):
2839 New functions, with the actual signal-handling code taken from the
2840 original respective signal handlers, sans the sporadic attempts to
2841 preserve errno, since that's now done by handle_on_main_thread.
2842 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
2843 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
2844 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
2846 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
2847 Move initialization of main_thread to sysdep.c's init_signals.
2848 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
2849 our usage, and simplifies the mainline code.
2850 (record_child_status_change): New static function, as a helper
2851 for handle_child_signal, and with most of the old child handler's
2853 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
2854 (handle_child_signal): Use the above.
2855 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
2856 Moved here from emacs.c.
2857 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
2858 code moved here from emacs.c's main function.
2859 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
2860 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
2861 This lets callers save and restore errno properly.
2863 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
2865 Remove redundant or unused things here and there.
2866 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
2867 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
2868 * editfns.c (Fcompare_buffer_substrings): Likewise.
2869 * frame.h (struct terminal, struct font_driver_list):
2870 Remove redundant declarations.
2871 * window.h (Qleft, Qright): Likewise.
2873 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
2875 Do not mark objects from deleted buffers, windows and frames.
2876 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
2877 (mark_object): Likewise for windows and frames.
2879 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
2881 * alloc.c (valid_lisp_object_p): Treat killed buffers,
2882 buffer_defaults and buffer_local_symbols as valid objects.
2883 Return special value to denote them.
2885 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
2887 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
2888 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
2889 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
2890 (file_name_absolute_p, Fsubstitute_in_file_name):

2896 * filelock.c (boot_time_initialized, get_boot_time)
2897 (get_boot_time_1, lock_file_1, within_one_second):
2898 * floatfns.c (in_float):
2899 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
2900 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
2901 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
2902 * lisp.h (struct Lisp_Hash_Table.cmpfn):
2903 * window.c (compare_window_configurations):
2904 Use bool for booleans.
2905 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
2906 (Fdefault_file_modes): Now mode_t, not int, for modes.
2907 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
2908 (internal_delete_file): Now returns void, not a (boolean) int,
2909 since nobody was looking at the return value.
2910 * lisp.h, window.h: Adjust to above API changes.
2912 * xdisp.c (set_message): Simplify and reindent last change.
2914 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
2916 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
2918 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
2920 * eval.c (call_debugger): Make the function non-static so that we
2921 can call it from set_message.
2923 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
2924 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
2926 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
2928 Give more-useful info on a fatal error (Bug#12328).
2929 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
2930 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
2931 of doing the work ourselves.
2932 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
2933 do most of the work.
2934 (fatal_error_backtrace): New function, taken from the guts
2935 of the old fatal_error_signal, but with a new option to output
2937 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
2938 info about the signal than just its number.
2939 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
2940 * sysdep.c: Include <execinfo.h>
2941 (emacs_backtrace): New function, taken partly from the previous
2942 code of the 'die' function.
2943 (emacs_abort): Call fatal_error_backtrace rather than abort.
2945 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
2947 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
2948 eager (load-time) macro-expansion.
2949 * lisp.mk (lisp): Add macroexp.
2951 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
2953 Simplify redefinition of 'abort' (Bug#12316).
2954 Do not try to redefine the 'abort' function. Instead, redo
2955 the code so that it calls 'emacs_abort' rather than 'abort'.
2956 This removes the need for the NO_ABORT configure-time macro
2957 and makes it easier to change the abort code to do a backtrace.
2958 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
2959 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
2960 Remove; sysdep.c's emacs_abort now takes its place.
2961 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
2962 'abort' changed to use 'emacs_abort'.
2963 * msdos.c (dos_abort) [defined abort]: Remove; not used.
2964 (abort) [!defined abort]: Rename to ...
2965 (emacs_abort): ... new name.
2966 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
2967 the place of the old 'abort' in emacs.c.
2968 * w32.c, w32fns.c (abort): Do not #undef.
2969 * w32.c (emacs_abort): Rename from w32_abort.
2971 2012-09-04 Eli Zaretskii <eliz@gnu.org>
2973 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
2974 offsets[j].dv, since the y axis of the screen coordinates points
2975 down, while the y axis of the font definition coordinates points
2976 up. This fixes display of Arabic diacritics such as KASRA and
2977 KASRATAN. (Bug#11860)
2979 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
2981 Be more systematic about _setjmp vs setjmp.
2982 * alloc.c (test_setjmp, mark_stack):
2983 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
2984 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
2985 (png_load, my_error_exit, jpeg_load):
2986 * process.c (send_process_trap, send_process):
2987 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
2988 The underscored versions are up to 30x faster on some hosts.
2989 Formerly, the code used setjmp+longjmp sometimes and
2990 _setjmp+_longjmp at other times, with no particular reason to
2991 prefer setjmp+longjmp.
2993 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
2995 Fix minor problem found by static checking.
2996 * buffer.c (Fdelete_all_overlays): Return nil.
2998 2012-09-03 Martin Rudalics <rudalics@gmx.at>
3000 * buffer.c (Fdelete_all_overlays): New function.
3002 2012-09-03 Chong Yidong <cyd@gnu.org>
3004 * gtkutil.c: Add extern decl for Qxft.
3006 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
3008 * emacs.c, eval.c: Use bool for boolean.
3009 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
3010 (malloc_using_checking) [DOUG_LEA_MALLOC]:
3011 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:

3015 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
3016 (maybe_call_debugger, Fbacktrace):
3017 * process.c (read_process_output, exec_sentinel):
3018 Use bool for booleans.
3019 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
3020 All callers changed.
3021 * eval.c (interactive_p): Omit always-true boolean argument
3022 EXCLUDE_SUBRS_P. All callers changed.
3023 * dispextern.h, lisp.h: Reflect above API changes.
3024 * firstfile.c (dummy): Use the address of 'main', whose signature
3025 won't change, instead of the address of 'initialize', whose
3026 signature just changed from int to bool.
3027 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
3028 * msdos.c (fatal_error_in_progress): ... from here.
3029 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
3031 (redisplay_internal, unwind_redisplay): Simply clear
3032 REDISPLAYING_P when unwinding, instead of saving its previous,
3033 always-false value and then restoring it.
3035 Clean up some extern decls.
3036 Mostly, this hoists extern decls out of .c files and into .h files.
3037 That way, we're more likely to catch errors if the interfaces change.
3038 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
3039 declare xg_mark_data.
3040 * dispextern.h (x_frame_parm_handlers):
3042 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
3043 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
3044 (Qultra_bold, Qoblique, Qitalic):
3045 Move extern decl here from .c file.
3046 * alloc.c (xg_mark_data) [USE_GTK]:
3048 * eval.c (Qlexical_binding):
3049 * fns.c (time) [!HAVE_UNISTD_H]:

3056 * widget.c (free_frame_faces):
3057 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
3058 * xfont.c (x_clear_errors):
3059 * xterm.c (x_frame_parm_handlers):
3060 Remove now-redundant extern decls.
3061 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
3062 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
3064 * xfaces.c: Remove unnecessary static decls.
3065 * xterm.c (updating_frame): Remove decl of nonexistent object.
3067 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
3068 when building globals.h, as the objects that are not built on
3069 this host are not needed to compile C files on this host.
3071 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
3073 * gtkutil.h: Remove prototype for x_wm_set_size_hint.
3075 * frame.h: Add missing prototype for x_wm_set_size_hint.
3077 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>

3111 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
3113 * makefile.w32-in (CCL_H, W32FONT_H): New macros.
3114 (ATIMER_H, FONT_H, $(BLD)/alloc.$(O), $(BLD)/callproc.$(O))

3119 ($(BLD)/w32font.$(O), $(BLD)/w32uniscribe.$(O)): Update dependencies.
3121 2012-09-01 Eli Zaretskii <eliz@gnu.org>
3123 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
3124 more than one grapheme cluster passed to the shaper: compute the
3125 offset adjustment values separately for each cluster. (Bug#11860)
3127 * image.c: Restore mistakenly removed inclusion of w32.h. Without
3128 it, GCC doesn't see prototypes of w32_delayed_load, and complains
3129 about implicit conversions from integer to pointer.
3131 2012-09-01 Daniel Colascione <dancol@dancol.org>
3133 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
3134 system used too early.
3136 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
3138 Better seed support for (random).
3139 * emacs.c (main): Call init_random.
3140 * fns.c (Frandom): Set the seed from a string argument, if given.
3141 Remove long-obsolete Gentzel cruft.

3151 x_set_menu_bar_lines, x_char_width, x_char_height, x_sync,
3152 x_set_tool_bar_lines, x_activate_menubar, and free_frame_menubar,
3153 all of which have been moved to common code.
3155 * xfaces.c: Include TERM_HEADER instead of listing all possible
3156 window-system headers.
3158 * w32xfns.c (x_sync): Correct definition of x_sync (a no-op here)
3161 * w32term.h (FRAME_X_WINDOW): Use FRAME_W32_WINDOW instead of
3162 directly accessing frame internals.
3164 * w32font.h: Include font.h. Define syms_of_w32font and
3167 * process.c: Include TERM_HEADER instead of listing all possible
3168 window-system headers.
3170 * nsterm.h: Remove declarations now in frame.h.
3171 Define FRAME_X_SCREEN, FRAME_X_VISUAL.
3173 * menu.c: Include TERM_HEADER instead of listing all possible
3174 window-system headers.
3176 * keyboard.h: Declare ignore_mouse_drag_p whenever we have a
3179 * keyboard.c: Include TERM_HEADER instead of listing all possible
3180 window-system headers.
3182 * image.c: Include TERM_HEADER instead of listing all possible
3183 window-system headers. Declare Vlibrary_cache when compiling for
3186 * gtkutil.h (xg_list_node_): Include xterm.h to pick up needed
3187 window system declarations.
3189 * frame.h: Move common functions here: set_frame_menubar,
3190 x_set_window_size, x_sync, x_get_focus_frame,
3191 x_set_mouse_position, x_set_mouse_pixel_position,
3192 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

3213 the current window system; include in list of objects to link into
3216 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
3218 Remove mark_ttys function and fix tty_display_info initialization.
3219 * lisp.h (mark_ttys): Remove prototype.
3220 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
3221 to mark_ttys because all possible values of 'top_frame' slot are
3222 the frames which are reachable from Vframe_list.
3223 * term.c (mark_ttys): Remove.
3224 (init_tty): Safely initialize 'top_frame' slot with Qnil.
3226 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
3228 Change struct frame bitfields from unsigned char to unsigned.
3229 * frame.h (struct frame): Change type of 'display_preempted',
3230 'visible', 'iconified', 'has_minibuffer', 'wants_modeline',
3231 'auto_raise', 'auto_lower', 'no_split', 'explicit_name',
3232 'window_sizes_changed', 'mouse_moved' and 'pointer_invisible'
3233 bitfields from unsigned char to unsigned.
3235 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
3237 Remove unused member of struct x_output and struct w32_output.
3238 * xterm.h (struct x_output): Remove unused field 'needs_exposure'.
3239 * w32term.h (struct w32_output): Likewise.
3241 2012-08-30 Jan Djärv <jan.h.d@swipnet.se>
3243 * gtkutil.c (x_wm_set_size_hint): Use 1 col for base_width so it
3244 does not become zero (Bug#12234).
3246 2012-08-30 Paul Eggert <eggert@cs.ucla.edu>
3248 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
3249 for GCC 4.7.1 x86-64.
3251 2012-08-30 Glenn Morris <rgm@gnu.org>
3253 * lread.c (init_lread): For out-of-tree builds, only add the
3254 source directory's site-lisp dir to the load-path if it exists,
3255 consistent with in-tree builds. (Bug#12302)
3257 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>
3259 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize
3260 button_values to NULL. Call setStykeMask so dialogs get a close button.
3261 (windowShouldClose:): Set window_closed.
3262 (dealloc): New member, free button_values.
3263 (process_dialog:): Make member function. Remove window argument,
3264 replace window with self. Count buttons and allocate and store values
3266 (addButton:value:row:): value is int with the name tag. Call setTag
3267 with tag. Remove return self, declare return value as void.
3268 (addString:row:): Remove return self, declare return value as void.
3269 (addSplit): Remove return self, declare return value as void.
3270 (clicked:): Remove return self, declare return value as void.
3271 Set dialog_return to button_values[seltag]. Code formatting change.
3272 (initFromContents:isQuestion:): Adjust call to process_dialog.
3273 Code formatting change.
3274 (timeout_handler:): Set timer_fired to YES.
3275 (runDialogAt:): Set timer_fired to NO.
3276 Handle click on close button as quit.
3278 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
3279 Add window_closed and button_values. Add void as return value for
3280 add(Button|String|Split). addButton takes int instead of Lisp_Object.
3281 Add process_dialog as new member.
3283 2012-08-28 Eli Zaretskii <eliz@gnu.org>
3285 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it
3286 is not one of the heaps we manage. (Bug#12242)
3288 2012-08-28 Glenn Morris <rgm@gnu.org>
3290 * eval.c (Fcalled_interactively_p): Doc fix. (Bug#11747)
3292 2012-08-28 Martin Rudalics <rudalics@gmx.at>
3294 * window.c (Fset_window_configuration): Remove handling of
3295 auto-buffer-name window parameter. Install revision of reverted
3298 2012-08-28 Dmitry Antipov <dmantipov@yandex.ru>

3301 * buffer.c (Fset_buffer_major_mode): Signal an error
3302 if the buffer is dead.
3303 (Fother_buffer, other_buffer_safely): Remove redundant
3306 2012-08-28 Dmitry Antipov <dmantipov@yandex.ru>
3308 Always use set_buffer_if_live to restore original buffer at unwind.
3309 * buffer.h (record_unwind_current_buffer): New function.
3310 * bytecode.c, dispnew.c, editfns.c, fileio.c, fns.c, insdel.c:
3311 * keyboard.c, keymap.c, minibuf.c, print.c, process.c, textprop.c:
3312 * undo.c, window.c: Adjust users.
3313 * buffer.c (set_buffer_if_live): Fix comment.
3315 2012-08-28 Dmitry Antipov <dmantipov@yandex.ru>
3317 Fix usage of set_buffer_internal.
3318 * buffer.h (set_buffer_internal): Make it BUFFER_INLINE.
3319 * buffer.c (set_buffer_if_live): Use set_buffer_internal.
3320 * coding.c (decode_coding): Omit redundant test.
3321 * fileio.c (decide_coding_unwind): Likewise.
3322 * fns.c (secure_hash): Likewise.
3323 * insdel.c (modify_region): Likewise.
3324 * keyboard.c (command_loop_1): Likewise.
3325 * print.c (PRINTFINISH): Likewise.
3326 * xdisp.c (run_window_scroll_functions): Use set_buffer_internal.
3328 2012-08-27 Paul Eggert <eggert@cs.ucla.edu>

3346 (change_frame_size_1, sit_for):
3347 Use bool for boolean.
3348 (clear_glyph_matrix_rows): Rename from enable_glyph_matrix_rows,
3349 and remove last int (actually boolean) argument, which was always 0.
3350 All callers changed.
3351 * dispextern.h, frame.h, lisp.h: Reflect above API changes.
3352 * dispextern.h (struct composition_it): Use bool for boolean.
3353 (struct glyph_matrix): Don't assume buffer sizes can fit in 'int'.
3354 (struct bidi_it): Use unsigned:1, not int, for boolean prev_was_pdf.
3355 * dired.c (file_name_completion):
3356 Use bool for boolean. (This was missed in an earlier change.)
3358 2012-08-27 Martin Rudalics <rudalics@gmx.at>
3360 * window.c (Fset_window_configuration): Revert first part of
3363 2012-08-27 Jan Djärv <jan.h.d@swipnet.se>
3365 * nsterm.h (NSPanel): New class variable dialog_return.
3367 * nsmenu.m (initWithContentRect:styleMask:backing:defer:):
3368 Initialize dialog_return.
3369 (windowShouldClose:): Use stop instead of stopModalWithCode.
3370 (clicked:): Ditto, and also set dialog_return (Bug#12258).
3371 (timeout_handler:): Use stop instead of abortModal. Send a dummy
3373 (runDialogAt:): Make ret Lisp_Object. Set it from dialog_return when
3376 2012-08-27 Paul Eggert <eggert@cs.ucla.edu>
3378 * composite.c, data.c, dbusbind.c, dired.c: Use bool for booleans.

3388 Use bool for booleans.
3389 * dired.c (file_name_completion):
3390 * process.h (fd_callback):
3391 Omit int (actually boolean) argument. It wasn't being used.
3393 * composite.h, lisp.h: Reflect above API changes.
3395 * cmds.c, coding.c: Use bool for booleans.
3396 * cmds.c (move_point, Fself_insert_command):

3417 * fileio.c (Finsert_file_contents):
3418 Use bool for booleans.
3419 * coding.h, lisp.h: Reflect above API changes.
3420 * coding.c: Remove unnecessary static function decls.
3421 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
3422 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
3423 not a boolean 'int', since callers never look at the return value.
3424 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
3425 * coding.h (decoding_buffer_size, encoding_buffer_size)
3426 (emacs_mule_string_char): Remove unused extern decls.
3427 (struct iso_2022_spec, struct coding_system):
3428 Use 'unsigned int : 1' for boolean fields, since there's more than one.
3429 (struct emacs_mule_spec): Remove unused field 'full_support'.
3430 All initializations removed.
3431 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
3433 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
3435 Fix spare memory change (Bug#12286).
3436 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
3437 (valid_lisp_object_p): Likewise.
3439 2012-08-27 Martin Rudalics <rudalics@gmx.at>
3441 * window.c (Fset_window_configuration): Record any window's old
3442 buffer if it's replaced (see Bug#8789). If the new current
3443 buffer doesn't appear in the selected window, go to its old
3446 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
3448 Special MEM_TYPE_SPARE to denote reserved memory.
3449 * alloc.c (enum mem_type): New memory type.
3450 (refill_memory_reserve): Use new type for spare memory.
3451 This prevents live_cons_p and live_string_p from incorrect
3452 detection of uninitialized objects from spare memory as live.
3454 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
3457 * Makefile.in (.PHONY): versioclean -> versionclean.
3459 Remove unused external symbols.
3460 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
3461 * window.c (Qwindow_valid_p, decode_valid_window):
3462 Now static, not extern.
3463 * data.c (Qinterval): Remove; unused.
3464 (syms_of_data): Do not define 'interval'.
3465 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
3466 * window.h (decode_valid_window):
3469 * character.c, charset.c, chartab.c: Use bool for booleans.
3470 * character.c (lisp_string_width, string_count_byte8)
3471 (string_escape_byte8):

3479 (char_table_set_range, optimize_sub_char_table)
3480 (map_sub_char_table):
3481 Use bool for boolean.
3482 * character.c (str_to_unibyte): Omit last boolean argument; it was
3483 always 0. All callers changed.
3484 * character.h, charset.h: Adjust to match previous changes.
3485 * character.h (char_printable_p): Remove decl of nonexistent function.
3486 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
3487 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
3488 are all boolean, so make them single-bit bitfields.
3490 * lisp.h (ASET): Remove attempt to detect side effects.
3491 It was meant to be temporary and it often doesn't work,
3492 because when IDX has side effects the behavior of IDX==IDX
3493 is undefined. See Stefan Monnier in
3494 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
3496 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
3498 * lisp.h (functionp): New function (extracted from Ffunctionp).
3499 (FUNCTIONP): Use it.
3500 * eval.c (Ffunctionp): Use it.
3502 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
3504 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
3505 as that's faster and simpler than static storage. Don't bother
3506 with the g_main_context_query overhead if g_main_context_pending
3507 says no events are pending.
3508 (gfds, gfds_size): Remove these static vars.
3509 (xgselect_initialize): Remove; no longer needed.
3510 All uses and decls removed.
3512 * emacs.c (fatal_error_signal_hook): Remove.
3513 All uses removed. This leftover from old code was always 0.
3515 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
3516 * casefiddle.c (casify_object, casify_region):
3517 * casetab.c (set_case_table):
3518 * category.c, category.h (word_boundary_p):
3519 * category.h (CHAR_HAS_CATEGORY):
3520 Use bool for booleans, instead of int.
3522 2012-08-25 Eli Zaretskii <eliz@gnu.org>
3524 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
3526 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
3528 On assertion failure, print backtrace if available.
3529 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
3530 (die) [ENABLE_CHECKING]: Print a backtrace if available.
3531 * Makefile.in (LIB_EXECINFO): New macro.
3534 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
3535 * bytecode.c (exec_byte_code):
3536 * callint.c (check_mark, Fcall_interactively):
3537 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
3538 (getenv_internal, sync_process_alive, call_process_exited):
3539 * lisp.h (USE_SAFE_ALLOCA):
3540 Use bool for booleans, instead of int.
3541 * lisp.h, process.h: Adjust prototypes to match above changes.
3542 * callint.c (Fcall_interactively): Don't assume the mark's
3543 offset fits in 'int'.
3545 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
3547 * buffer.c, buffer.h: Use bool for boolean.
3548 * buffer.c (reset_buffer_local_variables)
3549 (buffer_lisp_local_variables, Fset_buffer_modified_p)

3554 (mmap_enlarge, mmap_set_vars):
3555 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
3556 Use bool for booleans, instead of int.
3557 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
3558 since the 1-or-0 return value is always ignored anyway.
3559 (mmap_initialized_p):
3560 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
3561 * buffer.h, lisp.h: Adjust prototypes to match above changes.
3563 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
3565 * bidi.c: Use bool for boolean.
3566 This is a bit more readable, and makes the text segment of bidi.o
3567 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
3568 Presumably it's faster too.
3569 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
3571 (bidi_cache_find_level_change, bidi_cache_iterator_state)
3572 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)

3574 (bidi_explicit_dir_char, bidi_level_of_next_char)
3575 (bidi_find_other_level_edge, bidi_move_to_visually_next):
3576 Use bool for booleans, instead of int.
3577 * dispextern.h (bidi_init_it, bidi_paragraph_init)
3578 (bidi_unshelve_cache): Adjust decls to match code.
3580 2012-08-23 Martin Rudalics <rudalics@gmx.at>
3582 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
3585 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
3587 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
3588 * atimer.h: Include <stdbool.h>.
3590 2012-08-22 Dan Nicolaescu <dann@gnu.org>
3592 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
3593 compile time tests instead of run time tests on systems that do
3595 (FRAME_MAC_P): Remove leftover from deleted code.
3596 * frame.c (syms_of_frame): Remove leftover from deleted code.
3598 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
3600 * nsterm.m (insertText:): Don't clear modifiers if code is space.
3602 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
3604 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
3605 Otherwise, the compiler complains about (A?B:C) where B is void
3606 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
3607 (fontset_add): Return void, for FONTSET_ADD.
3609 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
3611 * alloc.c: Use bool for booleans.
3612 (gc_in_progress, abort_on_gc)
3613 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
3614 (dont_register_blocks) [GC_MALLOC_CHECK]:
3615 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
3616 (check_string_bytes, make_specified_string, memory_full)
3617 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
3618 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
3619 (mark_stack, valid_pointer_p, make_pure_string)
3620 (Fgarbage_collect, survives_gc_p, gc_sweep):
3621 Use bool for booleans, instead of int.
3622 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
3623 Remove unused local.
3624 * alloc.c (PURE_POINTER_P):
3625 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
3626 * editfns.c (Fformat):
3627 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
3629 * fns.c (sweep_weak_table):
3630 * lisp.h (suppress_checking, push_message, survives_gc_p)
3631 (make_pure_string, gc_in_progress, abort_on_gc):
3632 * lread.c (readchar, read1):
3633 * print.c (Fprin1_to_string):
3634 * xdisp.c (push_message):
3635 Use bool for booleans affected directly or indirectly by
3638 Make recently-introduced setters macros.
3639 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
3640 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
3641 (set_fontset_default, set_fontset_fallback): Rename from their
3642 upper-case counterparts, and make them functions rather than macros.
3643 This is more consistent with the other recently-introduced setters.
3644 These don't need to be inline, since they're local.
3646 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
3648 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
3649 the loop (Bug#12247).
3651 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
3653 * lisp.h (vcopy): Use memcpy rather than our own loop.
3654 This fixes a performance regression introduced by the recent
3655 addition of vcopy. This means 'vcopy' will need to be modified

3753 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
3755 Rely on <config.h> + <unistd.h> to declare 'environ',
3756 as gnulib does this if the system doesn't.
3757 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:

4628 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
4629 * w32.c (init_environment): Change the default values of many
4630 environment variables in dflt_envvars[] to NULL, to avoid pushing
4631 them into environment when they were not already defined.
4632 Remove the code that deletes site-lisp subdirectories from the default
4633 value of EMACSLOADPATH, as it is no longer needed.
4634 (check_windows_init_file): Now external, not static.
4635 Use Vload_path as is, without adding anything, as this function is now
4636 called when Vload_path is already set up.
4638 * w32.h (check_windows_init_file): Add prototype.
4640 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build
4641 directory, ignore the /*/i386/ tail in Vinvocation_directory, for
4642 compatibility with Posix platforms.
4643 (main): Move the call to check_windows_init_file to here from
4645 (decode_env_path) [WINDOWSNT]: Expand the %emacs_dir%/ prefix, if
4646 any, in the DEFALT argument into the root of the Emacs build or
4647 installation tree, as appropriate.
4649 * callproc.c (init_callproc_1): Call decode_env_path instead of
4650 doing its equivalent by hand.
4651 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
4652 the code that sets Vexec_path run on MS-Windows.

4664 Now constants, not macros.
4666 2012-08-03 Paul Eggert <eggert@cs.ucla.edu>
4668 Remove unnecessary casts involving pointers.
4669 These casts are no longer needed now that we assume C89 or later,
4670 since they involve casting to or from void *.

4683 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
4684 Remove unnecessary pointer casts.
4685 * alloc.c (record_xmalloc): New function.
4686 * lisp.h (record_xmalloc): New decl.
4687 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
4688 more like a function. This is because the pointer cast is not
4689 needed. All uses changed.
4690 * print.c (print_string, print_error_message): Avoid length recalc.
4692 Improve fix for macroexp crash with debugging (Bug#12118).
4693 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
4694 ARRAY_MARK_FLAG when checking subscripts, because ASET is
4695 not supposed to be invoked from the garbage collector.
4696 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
4697 (gc_aset): New function, which is like ASET but can be
4698 used in the garbage collector.
4699 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)

4711 (GetSecurityInfo_Proc, CreateSymbolicLink_Proc): New typedefs.
4712 (map_w32_filename): Improve commentary. Simplify switch.
4713 (SYMBOLIC_LINK_FLAG_DIRECTORY): Define if not defined in system
4714 headers (most versions of MinGW w32api don't).
4715 (get_security_info, create_symbolic_link)
4716 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
4718 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
4719 in the argument file name.

4722 (sys_rename): Diagnose renaming of a symlink when the user doesn't
4723 have the required privileges.
4724 (get_file_security_desc_by_name): Rename from
4725 get_file_security_desc.
4726 (stat_worker): New function, with most of the guts of 'stat', and
4727 with addition of handling of symlinks and support for 'lstat'.
4728 If possible, get file's attributes and security information by
4729 handle, not by name. Produce S_IFLNK bit for symlinks, when
4730 called from 'lstat'.
4731 (stat, lstat): New functions, call 'stat_worker'.
4732 (symlink, readlink, careadlinkat): Rewritten to create and resolve
4733 symlinks when the underlying filesystem supports them.
4735 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
4737 Fix macroexp crash on Windows with debugging (Bug#12118).
4738 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
4739 checking subscripts; problem introduced with the recent
4740 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
4741 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
4742 since it's used in non-static inline functions now.
4744 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
4745 Don't assume buffer size fits in 'int'. Remove unused local.
4747 Use C99-style 'extern inline' if available.

4762 * category.c (CATEGORY_INLINE):
4763 * character.c (CHARACTER_INLINE):
4764 * charset.c (CHARSET_INLINE):
4765 * composite.c (COMPOSITE_INLINE):
4766 * dispnew.c (DISPEXTERN_INLINE):
4767 * sysdep.c (SYSTIME_INLINE):
4768 Define to EXTERN_INLINE, so that the corresponding functions
4769 are compiled into code.
4770 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
4771 (INLINE_HEADER_END): New macros.
4772 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

4792 hard-coding the path separator.
4794 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
4796 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
4797 This how ASET and AREF are supposed to work, and makes
4798 it easier to think about future improvements. See
4799 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
4800 * charset.h (set_charset_attr): New function.

5053 * s/aix4-2.h (sigmask): No need to undefine it, since syssignal.h
5054 does that unconditionally. Remove file, which is now empty.
5056 * s/freebsd.h, s/gnu-linux.h, s/sol2-6.h, s/unixware.h:
5059 2012-07-30 Paul Eggert <eggert@cs.ucla.edu>

5177 * w32inevt.c: Include w32inevt.h.
5178 (w32_read_console_input): New inline function, calls either
5179 ReadConsoleInputA or ReadConsoleInputW, depending on the value of
5180 w32_console_unicode_input.
5181 (fill_queue): Call w32_read_console_input instead of ReadConsoleInput.
5182 (w32_kbd_patch_key, key_event): Use the codepage returned by
5183 GetConsoleCP, rather than the ANSI codepage returned by GetLocaleInfo.
5184 (key_event): use uChar.UnicodeChar only if

5215 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
5216 enumeration constants, as PURE and HEAP are too general, and clash
5217 with other headers and sources, such as gmalloc.c and the
5218 MS-Windows system headers. All users changed.
5220 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
5222 Revert last save_excursion_save and save_excursion_restore changes.
5223 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

5233 2012-07-27 Paul Eggert <eggert@cs.ucla.edu>
5235 Improve GDB symbol export (Bug#12036).
5236 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
5237 arms of an 'if', not using conditional expressions; otherwise GDB
5238 complains about the types in the unevaluated arm when the argument
5239 is an integer literal.
5240 (xgetint): Simplify expression.
5241 * alloc.c (gdb_make_enums_visible): New constant. This ports to
5242 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
5243 Zaretskii in <http://bugs.gnu.org/12036#13>.
5244 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
5245 needed now that we have gdb_make_enums_visible.
5246 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
5247 (enum enum_USE_LSB_TAG):
5248 New enum types, packaging up enums that need to be exported to GDB.

5266 * xdisp.c (syms_of_xdisp): Likewise.
5267 * xfns.c (syms_of_xfns): Likewise.
5269 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
5271 Fast save_excursion_save and save_excursion_restore.
5272 * lisp.h (struct Lisp_Excursion): New data type.
5273 (PVEC_EXCURSION): New pseudovector type.
5274 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
5275 to deal with it. Adjust comments.

5289 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
5290 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
5291 emacs.c, as this is a more-suitable home. Had this been done earlier
5292 the fix for 12036 would have avoided some of the problems noted in
5293 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
5294 would have been more obvious.
5295 * emacs.c: Do not include <verify.h>; no longer needed.
5296 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
5297 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
5298 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
5299 Remove; now done in lisp.h.

5304 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
5305 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
5306 not be usable in #if. This simplifies things.
5308 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
5310 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
5312 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

5315 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
5316 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
5317 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
5318 Adjust to changes in lisp.h and emacs.c, by using
5319 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
5320 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
5321 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
5322 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
5323 instead of gdb_valbits.
5324 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
5325 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
5326 instead of gdb_array_mark_flag.
5327 (xboolvector): Get size from $->size, not $->header.size.
5328 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
5329 (xreload, hook-run, hookpost-run): Remove.
5330 * emacs.c: Include <verify.h>.
5331 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
5332 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
5334 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
5335 (gdb_USE_LSB_TAG): New enum constants.
5336 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
5337 Also define these as enum constants, so they're visible to GDB.
5338 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
5339 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
5340 as constants, so they're visible to GDB.
5341 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
5342 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
5343 Now enum constants, not macros, so they're visible to GDB.
5344 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
5345 more convenient now. All uses changed.
5346 (VALMASK) [USE_LSB_TAG]: Also define in this case.
5347 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
5349 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>
5351 Explicitly free restriction data that are not needed anymore.
5352 * editfns.c (save_restriction_restore): Free restriction data.
5354 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
5356 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
5357 add argument, tune behavior, and adjust all callers.
5359 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
5361 Use typedef for EMACS_INT, EMACS_UINT.
5362 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
5363 than macros. This simplifies debugging in the usual case, since
5364 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
5365 and it allows expressions involving EMACS_INT casts.
5366 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
5368 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

5376 that FOCUS-FRAME can be omitted.
5378 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
5380 Adjust buffer text indirection counters at the end of Fkill_buffer.
5381 * buffer.c (Fkill_buffer): Adjust indirection counters when the
5382 buffer is definitely dead. This should really fix an issue reported
5383 by Christoph Scholtes again. (Bug#12007).
5384 (init_buffer_once): Initialize indirection counters of
5385 buffer_defaults and buffer_local_symbols (for sanity and safety).
5387 2012-07-24 Eli Zaretskii <eliz@gnu.org>
5389 * xdisp.c (init_iterator): Don't compute dimensions of truncation
5390 and continuation glyphs on tooltip frames, leave them at zero.
5391 Avoids continued lines in tooltips. (Bug#11832)
5393 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
5395 Simplify copy_overlay.
5396 * buffer.c (copy_overlay): Simplify. Use build_marker.

5402 or invalid. (Bug#12025)
5404 * window.c (decode_any_window): Disable CHECK_LIVE_FRAME test, as
5405 it signals an error when a tooltip frame is being created.
5407 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
5409 Cleanup miscellaneous objects allocation and initialization.
5410 * alloc.c (allocate_misc): Change to static. Add argument to
5411 specify the subtype. Adjust comment and users.

6186 The functional style also makes code easier to read and maintain.
6187 * systime.h: Include <sys/time.h> on all hosts, not just if

6223 (menu_separator_name_p):

6228 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
6229 Prefer snprintf to strncpy.
6230 * nsterm.m (ns_term_init):
6231 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
6232 * nsterm.m (ns_term_init):
6233 Avoid the need for strncpy, by using build_string or
6234 make_unibyte_string directly. Use dtoastr, not snprintf.
6235 * process.c (Fmake_network_process): Diagnose service names that
6236 are too long, rather than silently truncating them or creating
6237 non-null-terminated names.

6312 Stop ns builds setting the EMACSLOADPATH environment variable.
6313 * nsterm.m (ns_load_path): Rename from ns_init_paths.
6314 Now it does not set EMACSLOADPATH, just returns the load-path string.
6315 * nsterm.h: Update accordingly.
6316 * lread.c [HAVE_NS]: Include nsterm.h.
6317 (init_lread) [HAVE_NS]: Use ns_load_path.
6318 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
6320 2012-07-09 Glenn Morris <rgm@gnu.org>
6322 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
6323 since the included bsd-common.h does so.
6325 Stop ns builds setting the EMACSPATH environment variable.
6326 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
6327 (ns_init_paths): Do not set EMACSPATH.
6328 * nsterm.h (ns_exec_path): Add it.
6329 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
6332 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
6334 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
6336 * process.c (wait_reading_process_output): 'waitchannels' was unset
6337 when read_kbd || !NILP (wait_for_cell); fix this.
6339 Add GCC-style 'const' attribute to functions that can use it.
6340 * character.h (char_resolve_modifier_mask):
6341 * keyboard.h (make_ctrl_char):
6342 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
6343 (init_character_once, next_almost_prime, init_fns, init_image)
6344 (flush_pending_output, init_sound):

6349 Declare the dummy function with ATTRIBUTE_CONST.
6350 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
6351 Add decls with ATTRIBUTE_CONST.
6353 Minor improvements to make_formatted_string.
6354 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
6355 where int is good enough, as vsprintf returns an int.
6356 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
6358 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
6360 Use make_formatted_string to avoid double length calculation.
6361 * lisp.h (make_formatted_string): New prototype.
6362 * alloc.c (make_formatted_string): New function.
6363 * buffer.c (Fgenerate_new_buffer_name): Use it.
6364 * dbusbind.c (syms_of_dbusbind): Likewise.
6365 * editfns.c (Fcurrent_time_zone): Likewise.
6366 * filelock.c (get_boot_time): Likewise.
6367 * frame.c (make_terminal_frame, set_term_frame_name)
6368 (x_report_frame_params): Likewise.
6369 * image.c (gs_load): Likewise.
6370 * minibuf.c (get_minibuffer): Likewise.

6381 * nsterm.h (ns_etc_directory): Add it.
6382 * callproc.c [HAVE_NS]: Include nsterm.h.
6383 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
6385 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
6387 Move marker debugging code under MARKER_DEBUG.
6388 * marker.c (MARKER_DEBUG): Move marker debugging code under
6389 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
6390 for bootstrap with --enable-checking (~3x slowdown reported
6391 by Juanma Barranquero <lekktu@gmail.com>).
6392 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
6394 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
6396 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
6397 See <http://bugs.gnu.org/11825#29>.
6399 2012-07-08 Eli Zaretskii <eliz@gnu.org>
6401 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
6402 has no font, use the frame's font. (Bug#11813)
6403 (display_line): Add commentary about displaying truncation glyphs
6405 (produce_special_glyphs): Move here from term.c.
6407 * term.c (produce_special_glyphs): Move to xdisp.c.
6409 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
6412 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
6414 * xdisp.c (display_line): Avoid warning about implicit declaration
6417 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
6419 * lisp.h: Remove empty conditional.
6421 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
6423 * lread.c (load_path_check): Now static.
6425 Fix some minor --with-ns problems found by static checking.
6426 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
6427 (x_set_font) [!HAVE_X_WINDOWS]:
6428 * image.c (xpm_load_image) [HAVE_NS]:
6429 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
6430 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
6431 Remove unused local.
6432 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
6433 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
6434 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
6435 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
6436 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
6437 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
6438 Fix pointer signedness problem.
6439 * xfaces.c (FRAME_X_FONT_TABLE):
6440 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
6442 2012-07-07 Glenn Morris <rgm@gnu.org>
6444 * lread.c (load_path_check): New function, split from init_lread.
6445 (init_lread): Reorganize. Motivation:
6446 If EMACSLOADPATH is set, check/warn about that rather than the
6447 defaults, which we are not going to use. Hence we can remove
6448 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
6449 Don't warn if site-lisp directories are missing.
6450 If not installed, start from a blank load-path, since
6451 PATH_LOADSEARCH refers to the eventual installation directories.
6453 2012-07-07 Eli Zaretskii <eliz@gnu.org>
6455 Support truncation and continuation glyphs on GUI frames, when
6456 fringes are disabled. (Bug#11832)
6457 * xdisp.c (init_iterator): Get dimensions of truncation and
6458 continuation glyphs even if on GUI frames.
6459 Adjust it->last_visible_x on GUI frames when the left or right fringes,
6460 or both, are absent.
6461 (start_display, move_it_in_display_line_to): Handle the case of a
6462 GUI frame without a fringe to display continuation or truncation
6464 (insert_left_trunc_glyphs): Support GUI frames: make sure
6465 truncation glyphs overwrite enough glyphs from the current line to
6466 have sufficient space in pixels.
6467 (display_line): Support truncation and continuation glyphs on GUI
6468 frames. If some spare pixels are left on the line after inserting
6469 the truncation glyphs, fill that space with a stretch glyph of a
6470 suitably computed width.
6472 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
6473 produce_glyphs, to support GUI sessions.
6475 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
6477 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
6479 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
6481 Do not require float-time's arg to fit in time_t (Bug#11825).
6482 This works better on hosts where time_t is unsigned, and where
6483 float-time is applied to the (negative) difference between two times.
6484 * editfns.c (decode_time_components): Last arg is now double *,
6485 not int *, and means to store all the result as a double, without
6486 worrying about whether the seconds part fits in time_t.
6487 All callers changed.
6488 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
6489 All callers changed.
6490 (Ffloat_time): Do not fail merely because the specified time falls
6491 outside of time_t range.
6493 2012-07-07 Glenn Morris <rgm@gnu.org>
6495 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

6499 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
6501 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
6502 Update dependencies.
6504 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
6506 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
6508 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).

6510 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
6511 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
6512 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
6513 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
6515 * xfont.c (compare_font_names): Redo to omit the need for casts.
6517 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
6519 * xfns.c (Fx_change_window_property): Doc fix.
6520 * w32fns.c (Fx_change_window_property): Doc fix.
6522 * w32fns.c (Fx_window_property): Accept the same arguments as the
6523 X Windows version. Doc fix.
6524 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
6526 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
6527 Eli Zaretskii <eliz@gnu.org>
6529 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
6530 Windows-specific code from nt/config.nt moved here.
6531 Obsolete settings removed.
6533 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
6535 * process.c: Avoid unnecessary calls to gettime.
6536 (wait_reading_process_output): Don't get the time of day
6537 when gobbling data immediately and not waiting, as there's no need
6538 for it in that case. This removes a FIXME.
6540 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
6542 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
6543 is defined (Bug#11768).
6545 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6547 Fix marker debugging code.
6548 * marker.c (byte_char_debug_check): Do not perform the check
6549 if buffer is not multibyte.
6550 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
6551 Call byte_char_debug_check with correct arguments.
6553 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6555 Compile marker debugging code only if ENABLE_CHECKING is defined.
6556 * marker.c (byte_char_debug_check, count_markers):
6557 Use only if ENABLE_CHECKING is defined.
6558 (byte_debug_flag): Remove.
6559 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
6560 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
6562 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6564 Avoid code repetition in marker-related functions.
6565 * marker.c (attach_marker): New function.
6566 (Fset_marker, set_marker_restricted, set_marker_both)
6567 (set_marker_restricted_both): Use it.
6568 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
6569 Consistently rename charno to charpos.
6570 (marker_position): Add eassert.
6571 (marker_byte_position): Convert to eassert.

6586 * editfns.c (buildmark): Remove.
6587 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
6588 (save_restriction_save): Use build_marker.
6589 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
6590 * window.c (save_window_save): Likewise.
6592 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6594 Do not use Fdelete_overlay in delete_all_overlays
6595 to avoid redundant calls to unchain_overlay.
6596 * buffer.c (drop_overlay): New function.
6597 (delete_all_overlays, Fdelete_overlay): Use it.
6598 * minibuf.c (get_minibuffer): Fix comment.
6600 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
6602 Port to OpenBSD 5.1 amd64.
6603 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
6604 This is needed for OpenBSD, and should be harmless on all BSD systems.
6605 Also, include <sys/sysctl.h>, as it should be available on all
6606 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
6607 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
6608 use p_pid member, not kp_proc.pid.
6610 2012-07-06 Glenn Morris <rgm@gnu.org>
6612 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
6614 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
6616 More xmalloc and related cleanup.
6617 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
6618 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:

6623 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:
6624 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
6625 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
6627 Omit needless casts involving void * pointers and allocation.
6628 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
6629 as the former is more robust if P's type is changed.
6630 Prefer xzalloc to xmalloc + memset 0.
6631 Simplify malloc-or-realloc to realloc.
6632 Don't worry about xmalloc returning a null pointer.
6633 Prefer xstrdup to xmalloc + strcpy.
6634 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
6636 * keyboard.c (apply_modifiers_uncached): Prefer local array to
6637 alloca of a constant.
6639 2012-07-05 Eli Zaretskii <eliz@gnu.org>
6641 * xdisp.c (display_line): Fix horizontal pixel coordinates when
6642 hscroll is larger than the line width. Fixes long and futile
6643 looping inside extend_face_to_end_of_line (on a TTY) producing
6644 glyphs that are not needed and thrown away.
6646 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
6648 * marker.c (set_marker_restricted_both): Simplify by using

6662 followed by gtk_box_set_homogeneous (Bug#11768).
6663 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
6664 (update_theme_scrollbar_width, xg_create_scroll_bar):
6665 Use gtk_scrollbar_new (Bug#11768).
6666 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
6667 (is_box_type): New function (Bug#11768).
6668 (xg_tool_item_stale_p): Call is_box_type.
6669 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
6670 with default display (Bug#11768).
6672 2012-07-05 Eli Zaretskii <eliz@gnu.org>
6674 * xdisp.c (window_hscroll_limited): New function.
6675 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
6676 coordinates when window's hscroll is set to insanely large
6679 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
6681 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
6682 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
6684 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
6687 * lisp.h (xzalloc): New prototype. Omit needless casts.
6688 * alloc.c (xzalloc): New function. Omit needless casts.

6748 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
6749 This should be fixed in a better way; see Eli Zaretskii in
6750 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
6751 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
6753 * fileio.c (time_error_value): Rename from special_mtime.
6754 The old name's problems were noted by Eli Zaretskii in
6755 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
6757 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
6758 This variable's comment says Emacs needs at least one GDB-visible
6759 symbol of type enum pvec_type, to work around GDB problems.
6760 The symbol's value doesn't matter.
6762 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
6763 that causes compilation to fail on pre-C99 compilers.
6765 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
6767 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

6778 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
6779 * lisp.h (enum pvec_type): Use fewer bits.
6780 (PSEUDOVECTOR_SIZE_BITS): New constant.
6781 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
6782 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
6783 change in pvec_type.
6784 (PSEUDOVECTOR_TYPEP): New macro.
6785 (TYPED_PSEUDOVECTORP): Use it.

6788 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
6789 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
6790 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
6791 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
6792 (sweep_vectors): Use it. Use local var `total_bytes' instead of
6793 abusing vector->header.next.nbytes.
6794 (live_vector_p): Use PVEC_TYPE.
6795 (mark_object): Adapt code to extract pvectype. Use switch.
6797 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
6799 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
6800 Tighten new eassert a bit.
6802 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
6804 Fix compilation with --enable-gcc-warnings and -O1
6806 * doprnt.c (doprnt): Change type of tem to int, initialize
6807 to avoid compiler warning. Add eassert.
6808 * search.c (simple_search): Initialize match_byte to avoid
6809 compiler warning. Add eassert.
6811 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
6813 Avoid weird behavior with large horizontal scrolls.
6814 Without this change, for example, large hscroll values would
6815 mess up Emacs's display on Fedora 15 x86, presumably due to
6816 overflows in int calculations in the display code.
6817 Also, if buffers had long lines, Emacs would freeze.
6818 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
6819 (set_window_hscroll): New function, containing the old guts of
6820 Fset_window_hscroll. Return the clipped value.
6821 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
6822 This avoids the need to check against PTRDIFF_MAX.
6824 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
6826 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
6828 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
6830 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
6832 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
6833 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
6834 since GCC 4.4.6 issues a bogus warning for them.
6836 Fix bugs in file timestamp newness comparisons.
6837 * fileio.c (Ffile_newer_than_file_p):
6838 * lread.c (Fload): Use full timestamp resolution of files,
6839 not just the 1-second resolution, so that files that are only
6840 slightly newer still count as newer.
6841 * fileio.c (Ffile_newer_than_file_p): Don't assume file
6842 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
6844 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
6846 * fileio.c: Improve handling of file time marker. (Bug#11852)
6847 (special_mtime): New function.
6848 (Finsert_file_contents, Fverify_visited_file_modtime):
6849 Use it to set special mtime values consistently.
6851 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
6853 * fileio.c (Finsert_file_contents): Properly handle st_mtime
6854 marker for non-existing file. (Bug#11852)
6856 2012-07-03 Glenn Morris <rgm@gnu.org>
6858 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
6859 and did not make it into globals.h).
6861 2012-07-03 Tom Tromey <tromey@redhat.com>
6863 * window.c (Fset_window_margins, Fset_window_fringes)
6864 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
6865 * textprop.c (Fprevious_property_change): No longer static.
6866 * syntax.c (Fsyntax_table_p): No longer static.
6867 * process.c (Fget_process, Fprocess_datagram_address): No longer

6877 * doc.c (Fdocumentation_property, Fsnarf_documentation):
6879 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): No longer
6881 * dired.c (Ffile_attributes): No longer static.
6882 * composite.c (Fcomposition_get_gstring): No longer static.
6883 * callproc.c (Fgetenv_internal): No longer static.
6885 * ccl.h: Remove EXFUNs.
6886 * buffer.h: Remove EXFUNs.
6887 * dispextern.h: Remove EXFUNs.
6888 * intervals.h: Remove EXFUNs.
6889 * fontset.h: Remove EXFUN.
6890 * font.h: Remove EXFUNs.
6891 * dosfns.c (system_process_attributes): Remove EXFUN.
6892 * keymap.h: Remove EXFUNs.
6893 * lisp.h: Remove EXFUNs.
6894 * w32term.h: Remove EXFUNs.
6895 * window.h: Remove EXFUNs.
6896 * xsettings.h: Remove EXFUN.
6897 * xterm.h: Remove EXFUN.
6899 2012-07-03 Glenn Morris <rgm@gnu.org>
6901 * lisp.h (Frandom): Make it visible to C.
6902 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
6903 buffer for invisible buffers. (Bug#1229)

6907 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
6908 values which aren't power of 2.
6909 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
6910 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
6913 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
6915 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
6917 * alloc.c (mark_object): Revert part of last patch to use `switch'.
6919 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
6921 * alloc.c (allocate_vector_block): Remove redundant
6922 calls to mallopt if DOUG_LEA_MALLOC is defined.
6923 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
6924 avoid calls to mallopt if zero_vector is returned.
6926 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
6928 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
6929 is enabled, avoid dereferencing NULL current_sblock if
6932 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
6934 Cleanup basic buffer management.
6935 * buffer.h (struct buffer): Change layout to use generic vector
6936 marking code. Fix some comments. Change type of 'clip_changed'
6937 to bitfield. Remove unused #ifndef old.
6938 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
6939 (GET_OVERLAYS_AT): Fix indentation.
6940 (for_each_per_buffer_object_at): New macro.
6941 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
6942 (Fbuffer_local_variables): Use it.
6943 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
6944 * alloc.c (allocate_buffer): Adjust to match new layout of
6945 struct buffer. Fix comment.
6946 (mark_overlay): New function.
6947 (mark_buffer): Use it. Use mark_vectorlike to mark normal
6948 Lisp area of struct buffer.
6949 (mark_object): Use it. Adjust marking of misc objects
6950 and related comments.
6952 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
6954 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
6955 wrapper that is not needed because the wrapped code is a no-op (zero
6956 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
6957 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
6959 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
6961 * alloc.c (mark_buffer): Simplify. Remove prototype.
6962 (mark_object): Add comment. Reorganize marking of vector-like
6963 objects. Use CHECK_LIVE for all vector-like objects except buffers
6964 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
6965 Avoid redundant calls to mark_vectorlike for bool vectors.
6967 2012-06-30 Glenn Morris <rgm@gnu.org>
6969 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
6971 * epaths.in (PATH_SITELOADSEARCH): New.
6972 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
6973 This is rather than relying on --enable-locallisppath elements
6974 having "site-lisp" in their names. (Bug#10208#25, 11658)
6976 2012-06-30 Eli Zaretskii <eliz@gnu.org>
6978 * w32proc.c (sys_select): Accept and ignore one more argument.
6980 * w32.c (emacs_gnutls_pull): Call select with one more argument.
6982 * sysselect.h [DOS_NT]: Don't include sys/select.h.
6983 (pselect) [!MS_DOS]: Redirect to sys_select.
6985 * sysdep.c: Don't include dos.h and dosfns.h.
6987 * process.c (sys_select):
6988 * msdos.c (sys_select): Accept one more argument and ignore it.
6990 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
6991 adapt data types and code to that.
6994 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
6995 which clashes with the gnulib function of the same name.
6997 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
6999 * font.c (font_style_to_value, font_style_symbolic)
7000 (font_prop_validate_style): Add type checks for values in
7003 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
7005 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
7008 2012-06-29 Eli Zaretskii <eliz@gnu.org>
7010 * xdisp.c (try_window_id): Undo last change.
7012 * w32.c (getwd): Adjust commentary about startup_dir.
7013 (init_environment): Always call sys_access, even in non-MSVC
7014 builds. Don't chdir to the directory of the Emacs executable.
7015 This undoes code from 1997 which was justified by the need to
7016 "avoid conflicts when removing and renaming directories". But its
7017 downside was that every relative file name was being interpreted
7018 relative to the directory of the Emacs executable, which can never
7019 be TRT. In particular, it broke sys_access when called with
7020 relative file names.
7021 (sys_access): Map GetLastError to errno.
7023 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
7025 * window.h (struct window): Change type of 'fringes_outside_margins'

7029 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
7032 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
7034 * gnutls.c (emacs_gnutls_handshake):
7035 Add QUIT to make the loop interruptible.
7037 2012-06-29 Glenn Morris <rgm@gnu.org>
7039 * charset.c (init_charset): Make lack of etc/charsets fatal.
7041 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
7043 * editfns.c (region_limit): Fix type mismatch.
7045 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
7047 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
7048 undefined. Convert from xassert to eassert.
7049 * nsmenu.m: Convert from xassert to eassert.
7050 * nsterm.m: Likewise.
7052 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
7054 * editfns.c (region_limit): Clip to narrowing (bug#11770).
7056 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
7058 Avoid integer overflow on scroll-left and scroll-right.
7059 * window.c (HSCROLL_MAX): New macro.
7060 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
7061 overflow when requested scroll falls outside ptrdiff_t range.
7063 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
7065 * window.h (struct window): Change type of 'hscroll',
7066 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
7067 'last_modified' and 'last_overlay_modified' to EMACS_INT.
7068 Adjust users accordingly.
7069 * xdisp.c (try_cursor_movement): Replace type check with eassert.
7070 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
7071 from EMACS_INT to ptrdiff_t.
7072 (make_window): Omit redundant initialization.
7074 2012-06-28 Juanma Barranquero <lekktu@gmail.com>

7078 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
7080 * window.h (struct window): Change type of 'use_time' and
7081 'sequence_number' from Lisp_Object to int.

7083 * print.c (print_object): Likewise.
7084 * window.c (select_window, Fwindow_use_time, make_parent_window)
7085 (make_window): Likewise.

7091 Fix GLYPH_DEBUG usage assuming that it may be undefined,
7092 adjust comments accordingly.

7141 * alloc.c (allocate_string_data): Remove dead code.
7142 * xsettings.c (XSETTINGS_FONT_NAME): Move under HAVE_XFT to
7143 avoid GCC warning about unused macro.
7145 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
7147 * alloc.c (allocate_string): Omit intervals initialization.
7148 * alloc.c (make_uninit_multibyte_string): Initialize intervals
7149 as in make_pure_string and make_pure_c_string.
7151 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
7153 * alloc.c (allocate_string): Fix last change.
7155 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
7157 * alloc.c (allocate_string): Remove two redundant calls
7158 to memset, add explicit initialization where appropriate.

7205 * alloc.c: Remove build_string.
7206 * lisp.h: Define build_string as static inline. This provides
7207 a better opportunity to optimize away calls to strlen when the
7208 function is called with compile-time constant argument.
7209 * image.c (imagemagick_error): Convert to build_string.
7210 * w32proc.c (sys_spawnve): Likewise.
7211 * xterm.c (x_term_init): Likewise.
7213 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
7215 Use sprintf return value instead of invoking strlen on result.
7216 In the old days this wasn't portable, since some sprintf
7217 implementations returned char *. But they died out years ago and
7218 Emacs already assumes sprintf returns int.
7219 Similarly for float_to_string.
7220 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
7221 * ccl.c (ccl_driver):
7222 * character.c (string_escape_byte8):

7225 * print.c (print_object):
7226 * xdisp.c (message_dolog):
7227 * xfns.c (syms_of_xfns):
7228 Use sprintf or float_to_string result to avoid need to call strlen.
7229 * data.c (Fnumber_to_string):
7230 Use make_unibyte_string, since the string must be ASCII.
7231 * lisp.h, print.c (float_to_string): Now returns int length.
7232 * term.c (produce_glyphless_glyph):
7233 Use sprintf result rather than recomputing it.
7235 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
7236 * Makefile.in (ALL_CFLAGS):
7237 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.
7238 * gmalloc.c, regex.c: Include <config.h> unconditionally.

7242 * dispextern.h (xstrcasecmp): Define to library function
7243 strcasecmp if available.
7244 * xfaces.c: Do not use xstrcasecmp if strcasecmp is available.

7259 2012-06-25 Paul Eggert <eggert@cs.ucla.edu>
7261 * gtkutil.c (get_utf8_string): Remove redundant assignment.
7262 sprintf already null-terminates its output.
7264 * xfns.c (x_window): Remove redundant cast.
7266 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
7268 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
7269 `const char *' to `char *' to avoid compiler warning.
7271 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
7273 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
7274 instead of truncating it to 63 (admittedly a generous limit).

7404 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
7406 Support higher-resolution time stamps (Bug#9000).
7407 The time stamps are only nanosecond-resolution at the C level,
7408 since that's the best that any real-world system supports now.
7409 But they are picosecond-resolution at the Lisp level, as that's
7410 easy, and leaves room for future OS improvements.
7412 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
7415 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
7416 Don't get current time unless it's needed.
7418 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
7419 now provides it if it's absent.
7420 (start_atimer): Port to higher-res time stamps.
7421 Check for time stamp overflow. Don't get current time more
7422 often than is needed.
7424 * buffer.h (struct buffer): Buffer modtime now has high resolution.
7425 Include systime.h, not time.h.
7426 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
7428 * dired.c: Include stat-time.h.
7429 (Ffile-attributes): File times now have higher resolution.
7431 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
7432 (struct image): Timestamp now has higher resolution.
7434 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
7435 has at least microseconds now. All uses removed.
7436 (update_frame, update_single_window, update_window, update_frame_1)
7437 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
7438 (duration_to_sec_usec): Remove; no longer needed.
7440 * editfns.c (time_overflow): Now extern.
7441 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
7442 (float-time, Fformat_time_string, Fcurrent_time_string)
7443 (Fcurrent_time_zone): Accept and generate higher-resolution
7445 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
7446 (decode_time_components, lisp_seconds_argument): New functions.
7447 (make_time): Now static.
7448 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
7449 Report an error if the time is invalid, rather than having the caller
7452 * fileio.c: Include <stat-time.h>
7453 (Fcopy_file): Copy higher-resolution time stamps.
7454 Prefer to set the time stamp via a file descriptor if that works.

7456 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
7457 (Fvisited_file_modtime, Fset_visited_file_modtime):
7458 Support higher-resolution time stamps.
7460 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
7462 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
7464 * image.c (prepare_image_for_display, clear_image_cache)
7465 (lookup_image): Port to higer-resolution time stamps.
7467 * keyboard.c (start_polling, bind_polling_period):
7468 Check for time stamp overflow.
7469 (read_char, kbd_buffer_get_event, timer_start_idle)
7470 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
7471 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
7472 Port to higher-resolution time stamps. Do not assume time_t is signed.
7473 (decode_timer): New function. Timers are now vectors of length 9,
7474 not 8, to accommodate the picosecond component.
7475 (timer_check_2): Use it.
7477 * nsterm.m (select_timeout, timeval_subtract): Remove.
7478 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
7479 as they're a bit more accurate and handle overflow better.
7480 (ns_select): Change prototype to be compatible with pselect.
7481 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
7482 * nsterm.h (ns_select): Adjust prototype.
7484 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
7485 us-resolution time stamps.
7486 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
7488 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
7490 * lisp.h (time_overflow): New decl.
7491 (wait_reading_process_output): First arg is now intmax_t, not int,
7492 to accommodate larger waits.
7494 * process.h (struct Lisp_Process.read_output_delay):
7495 Now counts nanoseconds, not microseconds.
7496 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
7498 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
7499 (wait_reading_process_output):
7500 Port to ns-resolution time stamps.
7501 (Faccept_process_output, wait_reading_process_output):
7502 Check for time stamp overflow. Do not assume time_t is signed.
7503 (select_wrapper): Remove; we now use pselect.
7504 (Fprocess_attributes): Now generates ns-resolution time stamps.
7506 * sysdep.c: Include utimens.h. Don't include utime.h
7507 or worry about struct utimbuf; gnulib does that for us now.
7508 (gettimeofday): Remove; gnulib provides a substitute.
7509 (make_timeval): New function.
7510 (set_file_times): Now sets ns-resolution time stamps.
7511 New arg FD; all uses changed.
7512 (time_from_jiffies, ltime_from_jiffies, get_up_time)
7513 (system_process_attributes):
7514 Now returns ns-resolution time stamp. All uses changed.
7515 Check for time stamp overflow.
7517 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
7518 provides a substitute now.
7520 * systime.h: Include timespec.h rather than sys/time.h and time.h,
7521 since it guarantees struct timespec.
7522 (EMACS_TIME): Now struct timespec, so that we can support
7523 ns-resolution time stamps.
7524 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
7525 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
7526 (EMACS_USECS): Remove.
7527 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
7528 so multiply the arg by 1000 before storing it.
7529 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
7531 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
7532 Port to ns-resolution time stamps.
7533 (EMACS_TIME_NEG_P): Remove; replaced by....
7534 (EMACS_TIME_SIGN): New macro.
7535 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
7536 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
7537 (set_file_times, make_time, lisp_time_argument): Adjust signature.
7538 (make_timeval, make_lisp_time, decode_time_components): New decls.
7539 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
7540 that it mishandled time_t overflow. You can't compare by subtracting!
7541 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
7542 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
7544 * term.c: Include <sys/time.h>.
7545 (timeval_to_Time): New function, for proper overflow wraparound.

7548 * undo.c (record_first_change): Support higher-resolution time stamps
7550 (Fprimitive_undo): Use them when restoring time stamps.
7552 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
7553 (w32_get_internal_run_time):
7554 Port to higher-resolution Emacs time stamps.
7555 (ltime): Now accepts single 64-bit integer, as that's more convenient
7558 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
7560 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
7561 for compatibility with pselect. Support ns-resolution time stamps.
7563 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
7565 * xselect.c (wait_for_property_change, x_get_foreign_selection):
7566 Check for time stamp overflow, and support ns-resolution time stamps.
7568 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
7569 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
7570 (timeval_subtract): Remove; no longer needed.
7571 (XTflash, XTring_bell, x_wait_for_event):
7572 Port to ns-resolution time stamps. Don't assume time_t is signed.
7574 2012-06-22 Chong Yidong <cyd@gnu.org>

7578 2012-06-22 Eli Zaretskii <eliz@gnu.org>
7580 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
7581 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
7582 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
7583 staticidx goes up to 1597 out of 1600 = 0x640.)
7585 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
7587 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
7588 Otherwise, the umask might be mistakenly 0 while handling input signals.

7599 access to `contents' member of Lisp_Vector objects with AREF and ASET
7602 2012-06-19 Chong Yidong <cyd@gnu.org>
7604 * frame.c (delete_frame): When selecting a frame on a different

7609 (unwind_format_mode_line): Restore them.
7610 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
7612 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
7613 since tty frames can be explicitly named.
7614 (prepare_menu_bars): Likewise.
7616 * term.c (Ftty_top_frame): New function.
7618 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

7621 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
7622 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
7623 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
7624 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
7625 (METER_1, METER_2): Simplify.
7627 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>

7631 2012-06-18 Martin Rudalics <rudalics@gmx.at>
7633 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
7634 gets killed during executing of this function (Bug#11665).
7635 Try to always return Qt when the buffer has been actually killed.
7636 (Vkill_buffer_query_functions): In doc-string say that functions
7637 run by this hook should not change the current buffer.
7639 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
7641 Fix recently-introduced process.c problems found by static checking.

7659 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
7661 * lisp.h (eassert): Assume C89 or later.
7662 This removes the need for CHECK.
7663 (CHECK): Remove. Its comments about always evaluating its
7664 argument were confusing, as 'eassert' typically does not evaluate
7667 * coding.c (produce_chars): Use ptrdiff_t, not int.
7669 * xterm.c (x_draw_underwave): Check for integer overflow.
7670 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

7768 indexing into it->string_overlays array. (Bug#11653)
7769 (set_cursor_from_row): Use the leftmost glyph as GLYPH_BEFORE, not
7770 the rightmost. (Bug#11720)

7843 USE_LISP_UNION_TYPE + USE_LSB_TAG cleanup (Bug#11604)

7854 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
7855 code works fine either way, and efficiency is not a concern here,
7856 as the union type is for debugging, not for production.
7857 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
7858 Use an inline function on all platforms when using the union type,
7859 since this is simpler and 'static inline' can be used portably
7861 (LISP_INITIALLY_ZERO): New macro.
7862 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
7863 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.

7974 Block-based vector allocation of small vectors.
7975 * lisp.h (struct vectorlike_header): New field `nbytes',
7976 adjust comment accordingly.

8001 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
8003 * doprnt.c (doprnt): Truncate multibyte char correctly.
8004 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
8005 would mishandle a string argument "Xc" if X was a multibyte
8006 character of length 2: it would truncate after X's first byte
8007 rather than including all of X.
8009 2012-06-06 Chong Yidong <cyd@gnu.org>
8011 * buffer.c (word_wrap): Doc fix.

8060 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
8061 Convert pctcpu and pctmem to Lisp float properly.
8062 Let the compiler fold better, as 100.0/0x8000 is exact.
8064 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
8066 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of

8076 bitfields where appropriate, remove unused fields.
8077 * window.h (struct window): Remove unused 'last_mark_x' and
8078 'last_mark_y' fields. Rename 'mini_p' field to 'mini',

8081 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
8082 fields from Lisp_Object to bitfield. Adjust users accordingly.

8090 and 'double' in a couple of places.
8092 2012-05-31 Eli Zaretskii <eliz@gnu.org>
8094 * xdisp.c (handle_stop): Detect whether we have overlay strings
8095 loaded by testing it->current.overlay_string_index to be
8096 non-negative, instead of checking whether n_overlay_strings is
8097 positive. (Bug#11587)
8099 2012-05-31 Chong Yidong <cyd@gnu.org>
8101 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

8107 * search.c (search_buffer): Remove calls to
8108 r_alloc_inhibit_buffer_relocation, as it is now called by
8109 maybe_unify_char, which was the cause of relocation of buffer text
8112 2012-05-31 Eli Zaretskii <eliz@gnu.org>
8114 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
8115 for the duration of call to load_charset, to avoid problems with
8116 callers of maybe_unify_char that access buffer text through C
8119 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
8120 decrement the inhibition flag, instead of just setting or
8123 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
8125 Remove obsolete '#define static' cruft.
8126 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
8127 This #undef was "temporary" in 2000; it is no longer needed
8128 now that '#define static' has gone away.
8129 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
8130 (gray_bitmap_bits): Remove; no longer needed.
8131 All uses replaced with definiens.

8175 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
8176 Bug#9642, but explicitly check that the buffer the overlay would
8177 be moved to is live and rearrange lines to make sure that errors
8178 will not put the overlay in an inconsistent state.
8179 (Fdelete_overlay): Cosmetics.
8181 2012-05-28 Eli Zaretskii <eliz@gnu.org>
8183 * w32term.c (my_bring_window_to_top): New function.
8184 (x_raise_frame): Use handle returned by DeferWindowPos, which

8218 Only r_alloc_inhibit_buffer_relocation needed to be added;
8219 the others were already declared.
8221 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
8222 before checking whether it's out of range. Put the check inside
8224 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
8226 2012-05-27 Ken Brown <kbrown@cornell.edu>
8228 * callproc.c (Fcall_process): Restore a line that was accidentally
8229 commented out in the 2011-02-13 change (bug#11547).

8233 * lisp.h [REL_ALLOC]: Add prototypes for external functions
8234 defined on ralloc.c.
8236 * buffer.c [REL_ALLOC]: Remove prototypes of
8237 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
8238 they are now on lisp.h.
8240 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
8242 * search.c (search_buffer): Use it to inhibit relocation of buffer
8243 text while re_search_2 is doing its job, because re_search_2 is
8244 passed C pointers to buffer text. (Bug#11519)
8246 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
8249 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
8250 state after an additional call to move_it_in_display_line_to, keep
8251 the values of it->max_ascent and it->max_descent found for the
8253 (pos_visible_p): Revert the comparison against bottom_y to what it
8254 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
8257 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
8259 Fix coding-related core dumps with gcc -ftrapv.
8260 The code was computing A - B, where A and B are pointers, and B is
8261 random garbage. This can lead to core dumps on platforms that
8262 have special pointer registers, and it also leads to core dumps on
8263 x86-64 when compiled with gcc -ftrapv. The fix is to compute
8264 A - B only when B is initialized properly.
8265 * coding.c (coding_set_source, coding_set_destination): Return void.
8266 (coding_change_source, coding_change_destinations): New functions,
8267 with the old behaviors of coding_set_source and coding_set_destination.

8283 (initialize_w32_display): Initialize mouse-highlight data.
8285 * w32inevt.c: Include termchar.h and window.h.
8286 (do_mouse_event): Support mouse-autoselect-window. When the mouse
8287 moves, call note_mouse_highlight. If help_echo changed, call
8288 gen_help_event to produce help-echo message in the echo area.
8289 Call clear_mouse_face if mouse_face_hidden is set in the mouse
8292 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
8294 * lread.c (read1): Simplify slightly to avoid an overflow warning
8295 with GCC 4.7.0 on x86-64.
8297 2012-05-26 Eli Zaretskii <eliz@gnu.org>
8299 * bidi.c (bidi_mirror_char): Revert last change: an int is
8300 definitely wide enough here.
8302 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>

8316 Use int, not EMACS_INT, where int is wide enough.
8317 (inhibit_garbage_collection, Fgarbage_collect):
8318 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

8337 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
8338 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8339 (validate_region): Omit unnecessary test for b <= e,
8340 since that's guaranteed by the previous test.
8341 (adjust_overlays_for_delete): Avoid pos + length overflow.
8342 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
8343 (report_overlay_modification):
8344 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
8345 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):

8347 after the EMACS_INT -> ptrdiff_t change.

8354 not int, to avoid needless 32-bit limit on 64-bit hosts.
8355 (exec_byte_code): Use tighter memory-full test, one that checks
8356 for alloca overflow. Don't compute the address of the object just
8357 before an array, as that's not portable. Use EMACS_INT, not
8358 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
8359 * callint.c (Fcall_interactively):
8360 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

8372 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8373 (casify_object): Avoid integer overflow when overallocating buffer.
8374 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
8375 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
8376 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
8377 * category.h (CATEGORYP): Don't assume arg is nonnegative.
8378 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
8379 integers are now checked earlier. All uses replaced with XINT.
8381 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8382 For CCL_MapSingle, check that content and value are in int range.
8383 (ccl_driver, Fregister_code_conversion_map):
8384 Check that Vcode_version_map_vector is a vector.
8385 (resolve_symbol_ccl_program): Check that vector header is in range.
8386 Always copy the vector, so that we can check its contents reliably
8387 now rather than having to recheck each instruction as it's being
8388 executed. Check that vector words fit in 'int'.
8389 (ccl_get_compiled_code, Fregister_ccl_program)
8390 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
8391 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
8392 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
8393 contents are in range.
8394 (Fccl_execute_on_string): Check that status is in range.
8395 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
8396 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
8397 Accept and return EMACS_INT, not int, because callers can pass values

8404 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8405 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
8406 avoid mishandling large integers.

8416 (Fdefine_charset_internal): Check ranges here, more carefully.
8417 Don't rely on undefined behavior with signed left shift overflow.
8418 Don't assume unsigned int fits into fixnum, or that fixnum fits
8419 into unsigned int. Don't require max_code to be a valid fixnum;
8420 that's not true for gb10830 4-byte on a 32-bit host. Allow
8421 invalid_code to be a cons, for the same reason. Require code_offset
8422 to be a character. Avoid int overflow if max_char is close
8424 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
8425 this is intended anyway and avoids some undefined behavior.
8426 (load_charset_map): Pass unsigned, not int, as 2nd arg of
8427 INDEX_TO_CODE_POINT, as that's what it expects.
8428 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
8429 * charset.h (DECODE_CHAR): Return int, not unsigned;
8430 this is what was intended anyway, and it avoids undefined behavior.
8431 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
8432 integer-overflow issues.
8433 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
8434 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
8435 where the argument is EMACS_INT, and this behavior is not intended.
8436 * chartab.c (Fmake_char_table, Fset_char_table_range)
8437 (uniprop_get_decoder, uniprop_get_encoder):
8438 Don't assume fixnum fits in int.
8439 * cmds.c (move_point): New function, that does the gist of
8440 Fforward_char and Fbackward_char, but does so while checking
8441 for integer overflow more accurately.
8442 (Fforward_char, Fbackward_char): Use it.
8443 (Fforward_line, Fend_of_line, internal_self_insert)
8444 (internal_self_insert):
8445 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

9147 define them any more.

9155 * s/ms-w32.h (DATA_START):
9156 Move here from removed file m/intel386.h.
9157 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.

9236 (report_error, report_error_1, make_hdr, copy_sym)

9244 already have overlays loaded.
9245 (handle_single_display_spec): Before returning without displaying
9246 fringe bitmap, synchronize the bidi iterator with the main display
9247 iterator, by calling iterate_out_of_display_property.
9248 (iterate_out_of_display_property): Detect buffer iteration by
9249 testing that it->string is a Lisp string.
9250 (get_next_display_element): When the current object is exhausted,
9251 and there's something on it->stack, call set_iterator_to_next to
9252 proceed with what's on the stack, instead of returning zero.
9253 (set_iterator_to_next): If called at the end of a Lisp string,
9254 proceed to consider_string_end without incrementing string
9255 position. Don't increment display vector index past the end of
9256 the display vector. (Bug#11417)
9257 (pos_visible_p): Don't report a position visible when move_it_to
9258 stopped at the last line of window, which happens to be scanned
9259 backwards by the bidi iteration. (Bug#11464)
9261 2012-05-14 Eli Zaretskii <eliz@gnu.org>
9263 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
9264 and right-margin display specs even if the spec is invalid or we
9265 are on a TTY, and thus unable to display on the fringes.
9266 That's because the text with the property will not be displayed anyway,
9267 so we need to signal to the caller that this is a "replacing"
9268 display spec. This fixes display when the spec is invalid or we
9271 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
9273 * unexaix.c (make_hdr): Fix typo in prototype.
9274 This bug broke the build on AIX. Problem reported by Gilles Pion.
9276 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
9278 * keyboard.c (kbd_buffer_get_event): Read special events also in

9306 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
9308 * xgselect.c (xg_select): Put maxfds+1 into a var.
9309 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
9311 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
9313 2012-05-10 Dave Abrahams <dave@boostpro.com>
9315 * filelock.c (syms_of_filelock): New boolean create-lockfiles.

9323 Initialize xd_registered_buses.
9325 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
9327 Untag more efficiently if USE_LSB_TAG.
9328 This is based on a proposal by YAMAMOTO Mitsuharu in
9329 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
9330 For an admittedly artificial (nth 8000 longlist) benchmark on
9331 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
9332 Emacs's overall text size by 1%.
9333 * lisp.h (XUNTAG): New macro.
9334 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)

9337 * eval.c (Fautoload):
9338 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
9339 * frame.h (XFRAME): Use XUNTAG.
9341 Port recent dbusbind.c changes to 32-bit --with-wide-int.
9342 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
9343 Remove unportable assumptions about print widths of types like
9345 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
9346 intptr_t when converting between pointer and integer, to avoid GCC
9347 warnings about wrong width.
9349 2012-05-09 Eli Zaretskii <eliz@gnu.org>
9351 * w32proc.c (new_child): Force Windows to reserve only 64KB of
9352 stack for each reader_thread, instead of defaulting to 8MB
9353 determined by the linker. This avoids failures in creating
9354 subprocesses on Windows 7, see the discussion in this thread:
9355 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
9357 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
9359 Fix up display of the *Minibuf-0* buffer in the mini window.
9360 * keyboard.c (read_char): Don't clear the echo area if there's no
9362 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
9363 contents of *Minibuf-0*) if there's no message displayed in its stead.
9365 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
9367 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
9370 2012-05-06 Chong Yidong <cyd@gnu.org>
9372 * lisp.mk (lisp): Update.
9374 2012-05-05 Jim Meyering <meyering@redhat.com>
9376 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
9378 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
9380 * data.c (PUT_ERROR): New macro.
9381 (syms_of_data): Use it. Add new error type `user-error'.
9382 * undo.c (user_error): New function.
9383 (Fprimitive_undo): Use it.
9384 * print.c (print_error_message): Adjust print style for `user-error'.
9385 * keyboard.c (user_error): New function.
9386 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
9388 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
9390 Do not limit current-time-string to years 1000..9999.
9391 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
9392 (Fcurrent_time_string): Support any year that is supported by the
9393 underlying localtime representation. Don't use asctime, as it
9394 has undefined behavior for years outside the range -999..9999.
9396 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
9398 Fix race conditions involving setenv, gmtime, localtime, asctime.
9399 Without this fix, interrupts could mess up code that uses these
9400 nonreentrant functions, since setting TZ invalidates existing
9401 tm_zone or tzname values, and since most of these functions return
9402 pointers to static storage.
9403 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
9404 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
9405 Grow the critical sections to include not just invoking
9406 localtime/gmtime, but also accessing these functions' results
9407 including their tm_zone values if any, and any related TZ setting.
9408 (format_time_string): Last arg is now struct tm *, not struct tm **,
9409 so that the struct tm is saved in the critical section.
9410 All callers changed. Simplify allocation of initial buffer, partly
9411 motivated by the fact that memory allocation needs to be outside
9412 the critical section.
9414 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
9416 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
9417 with RESET_INTERVAL.
9419 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
9420 Remove duplicated buffer name initialization.
9422 2012-05-02 Jim Meyering <jim@meyering.net>
9424 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
9426 * xfns.c (x_window): Use xstrdup (Bug#11375).
9428 2012-05-02 Eli Zaretskii <eliz@gnu.org>
9430 * xdisp.c (pos_visible_p): If already at a newline from the
9431 display string before the 'while' loop, don't walk back the glyphs
9432 from it3.glyph_row. Solves assertion violation when the display
9433 string begins with a newline (egg.el). (Bug#11367)
9435 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
9437 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
9440 2012-05-01 Glenn Morris <rgm@gnu.org>
9442 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
9443 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
9444 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
9445 All were removed before 23.1.
9447 * dispnew.c: Remove HAVE_LIBNCURSES test;
9448 it is always true on relevant platforms.
9450 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
9451 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
9453 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
9455 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
9457 * .gdbinit (xpr): Remove checks for no longer existing misc types.
9458 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
9461 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
9463 Do not avoid creating empty evaporating overlays (Bug#9642).
9464 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
9465 That is, do not delete an evaporating overlay if it becomes
9466 empty after its bounds are adjusted to fit within its buffer.
9467 This fix caused other problems, and I'm reverting it until we get
9468 to the bottom of them.
9470 2012-04-27 Chong Yidong <cyd@gnu.org>
9472 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
9474 2012-04-27 Eli Zaretskii <eliz@gnu.org>
9476 * xdisp.c (pos_visible_p): If the window start position is beyond
9477 ZV, start the display from buffer beginning. Prevents assertion
9478 violation in init_iterator when the minibuffer window is scrolled
9481 * window.c (window_scroll_pixel_based): Likewise.
9483 2012-04-27 Chong Yidong <cyd@gnu.org>
9485 * keymap.c (where_is_internal): Doc fix (Bug#10872).
9487 2012-04-27 Glenn Morris <rgm@gnu.org>
9489 * fileio.c (Fcopy_file, Fset_file_selinux_context):
9490 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
9492 2012-04-27 Eli Zaretskii <eliz@gnu.org>
9494 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
9495 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
9497 2012-04-26 Eli Zaretskii <eliz@gnu.org>
9499 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
9500 display element, check also the underlying string or buffer
9501 character. (Bug#11341)
9503 * w32menu.c: Include w32heap.h.
9504 (add_menu_item): If the call to AppendMenuW (via
9505 unicode_append_menu) fails, disable Unicode menus only if we are
9506 running on Windows 9X/Me.
9508 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
9510 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
9511 (xgetint): Add missing shift for LSB tags.
9513 2012-04-24 Martin Rudalics <rudalics@gmx.at>
9515 * keyboard.c (read_char): Don't wipe echo area for select window
9516 events: These might get delayed via `mouse-autoselect-window'
9519 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
9521 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
9522 manipulation of :loaded-from data.
9524 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
9526 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
9527 now a cons (bug#11311).
9529 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
9531 Do not create empty overlays with the evaporate property (Bug#9642).
9532 * buffer.c (Fmove_overlay): Delete an evaporating overlay
9533 if it becomes empty after its bounds are adjusted to fit within
9534 its buffer. Without this fix, in a nonempty buffer (let ((o
9535 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
9536 yields an empty overlay that has the evaporate property, which is
9537 not supposed to happen.
9539 Fix minor GTK3 problems found by static checking.
9540 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
9541 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
9542 (struct _EmacsFixedClass, emacs_fixed_get_type):

9550 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
9551 (EMACS_FIXED_GET_CLASS): Remove; unused.
9552 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
9554 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
9555 Problem reported by Juanma Barranquero for Windows -Wunused-function.
9557 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
9559 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
9560 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
9561 (__malloc_size_t, __malloc_ptrdiff_t):
9562 Remove. All uses removed, replaced by the definiens if needed,
9563 since we can assume C89 or better now.
9564 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
9565 (protect_malloc_state, align, get_contiguous_space)
9566 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)

9572 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
9573 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
9574 Define using prototypes, not old style.
9575 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
9576 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
9577 (align): Don't assume that signed integer overflow wraps around.
9578 Omit unused local var.
9579 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
9580 (_free_internal_nolock, memalign, mallochook, reallochook):

9639 * alloc.c: Handle unusual debugging option combinations.
9640 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,

9698 farther than the first row after the header line, if any.
9699 Don't consider the header-line row as "partially visible", even if
9700 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)

9755 (r_alloc_free) [REL_ALLOC]: Move decls from here ...
9756 * lisp.h (r_alloc, r_alloc_free, r_re_alloc, r_alloc_reset_variable)
9757 [REL_ALLOC]: ... to here, to check interface.
9758 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
9759 Remove decls. This fixes an "It stinks!".
9761 * alloc.c (which_symbols): Fix alignment issue / type clash.
9763 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
9765 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

9783 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
9784 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
9785 no longer the default.
9786 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
9788 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
9790 * lread.c (lisp_file_lexically_bound_p):
9791 Fix hang at ";-*-\n" (bug#11238).
9793 2012-04-14 Eli Zaretskii <eliz@gnu.org>
9795 * xdisp.c (find_last_unchanged_at_beg_row): Don't consider a row
9796 "unchanged" if its end.pos is beyond ZV. (Bug#11199)
9798 2012-04-14 Jan Djärv <jan.h.d@swipnet.se>
9800 * nsterm.m (constrainFrameRect): Always constrain when there is only
9801 one screen (Bug#10962).
9803 2012-04-13 Ken Brown <kbrown@cornell.edu>
9805 * s/cygwin.h (PTY_OPEN): Don't try to close a bogus file descriptor.

9811 2012-04-11 Daniel Colascione <dancol@dancol.org>
9813 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
9814 against is gone. It's better to use vfork now so that when Cygwin
9815 gains a new, working vfork, we use it automatically (bug#10398).
9817 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
9819 * window.c (save_window_save): Obey window-point-insertion-type.

9825 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
9827 * alloc.c (lisp_align_malloc): Remove unneeded prototype.
9829 2012-04-10 Jason S. Cornez <jcornez@ravenpack.com> (tiny change)
9831 * keyboard.c: Override inhibit-quit after the third C-g (bug#6585).
9832 (force_quit_count): New var.
9833 (handle_interrupt): Use it.
9835 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
9837 * w32.c (w32_delayed_load): Record the full path of the library
9838 being loaded (bug#10424).
9840 2012-04-09 Glenn Morris <rgm@gnu.org>
9842 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
9843 not just in the obarray, before snarfing them. (Bug#11036)
9845 * Makefile.in ($(leimdir)/leim-list.el):
9846 Pass EMACS rather than BUILT_EMACS.
9848 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
9850 * process.c (make_process):
9851 * process.h: Add integer `gnutls_handshakes_tried' member to
9854 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.
9855 Add convenience `GNUTLS_LOG2i' macro.
9857 * gnutls.c (gnutls_log_function2i): Convenience log function.
9858 (emacs_gnutls_read): Use new log functions,
9859 `gnutls_handshakes_tried' process member, and
9860 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
9861 attempts per process (connection).
9863 2012-04-09 Chong Yidong <cyd@gnu.org>
9865 * eval.c (Fuser_variable_p, user_variable_p_eh)
9866 (lisp_indirect_variable): Functions deleted.
9867 (Fdefvar): Caller changed.
9869 * callint.c (Finteractive, Fcall_interactively):
9870 * minibuf.c (Fread_variable): Callers changed.
9872 2012-04-09 Eli Zaretskii <eliz@gnu.org>
9874 * xdisp.c (set_cursor_from_row): If the display string appears in
9875 the buffer at position that is closer to point than the position
9876 after the display string, display the cursor on the first glyph of
9877 the display string. Fixes cursor display when a 'display' text
9878 property immediately follows invisible text. (Bug#11094)
9880 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
9882 composite.c: use 'double' consistently
9883 * composite.c (get_composition_id): Use 'double' consistently
9884 instead of converting 'float' to 'double' and vice versa; this is
9885 easier to understand and avoids a GCC warning.
9887 2012-04-09 Glenn Morris <rgm@gnu.org>
9889 * Makefile.in: Generate leim-list with bootstrap-emacs, in
9890 preparation for dumping it with emacs. (Bug#4789)
9891 (leimdir): New variable.
9892 ($(leimdir)/leim-list.el): New rule.
9893 (emacs$(EXEEXT)): Depend on leim-list.el.
9895 * buffer.c (Qucs_set_table_for_input): Remove. (Bug#9821)
9896 (Fget_buffer_create): Don't call Qucs_set_table_for_input.
9897 (init_buffer_once, syms_of_buffer): Remove Qucs_set_table_for_input.
9899 2012-04-08 Andreas Schwab <schwab@linux-m68k.org>
9901 * lisp.h (struct Lisp_Symbol): Add explicit padding to ensure
9904 2012-04-07 Juanma Barranquero <lekktu@gmail.com>
9906 * xml.c (init_libxml2_functions) [WINDOWSNT]:
9907 Remove unused local variable.
9909 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
9911 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
9912 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
9913 (mark_memory): Mark Lisp_Objects only if pointers might hide in
9914 objects, as mark_maybe_pointer will catch them otherwise.
9915 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
9916 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
9918 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
9920 Fix typo that broke non-Windows builds.
9921 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.
9923 2012-04-07 Eli Zaretskii <eliz@gnu.org>
9925 Support building on MS-Windows with libxml2.
9927 * makefile.w32-in (OBJ2): Add xml.$(O).
9928 (GLOBAL_SOURCES): Add xml.c.
9929 ($(BLD)/xml.$(O)): New dependency list.
9931 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
9932 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
9933 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
9934 [!WINDOWSNT]: New macros.
9935 (init_libxml2_functions, libxml2_loaded_p): New functions.
9936 (parse_region): Call fn_xmlCheckVersion instead of using the macro
9937 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
9938 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
9939 Calls xmlCleanupParser only if libxml2 was loaded (or statically
9941 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
9942 Call init_libxml2_functions before calling libxml2 functions.
9943 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
9945 * emacs.c: Don't include libxml/parser.h.
9946 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
9947 xmlCleanupParser directly.
9949 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
9951 2012-04-07 Eli Zaretskii <eliz@gnu.org>
9953 * indent.c (Fvertical_motion): If there is a display string at
9954 point, use it.vpos to compute how many lines to backtrack after
9955 move_it_to point. (Bug#11133)
9957 2012-04-06 Eli Zaretskii <eliz@gnu.org>
9959 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
9960 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
9961 about subtle differences between FETCH_CHAR* and STRING_CHAR*
9962 macros related to unification of CJK characters. For the details,
9963 see the discussion following the message here:
9964 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
9966 2012-04-04 Chong Yidong <cyd@gnu.org>
9968 * keyboard.c (Vdelayed_warnings_list): Doc fix.
9970 2012-04-01 Eli Zaretskii <eliz@gnu.org>
9972 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
9973 instead of alloca. (Bug#11138)
9975 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
9977 * w32menu.c (is_simple_dialog): Properly check lisp types.
9980 2012-03-31 Eli Zaretskii <eliz@gnu.org>
9982 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
9983 position we get to after a call to move_it_to fails the
9984 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
9985 only if we wind up in a string from display property. (Bug#11063)
9987 * window.c (Fdelete_other_windows_internal): Invalidate the row
9988 and column information about mouse highlight, so that redisplay
9989 restores it after reallocating the glyph matrices. (Bug#7464)
9991 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
9992 string comes from a `display' text property, use the buffer
9993 position of that property as if we actually saw that position in
9995 (move_it_by_lines): Remove the assertion that
9996 "it->current_x == 0 && it->hpos == 0" which can be legitimately
9997 violated when there's a before-string at the beginning of a line.
10000 2012-03-30 Eli Zaretskii <eliz@gnu.org>
10002 * xdisp.c (append_space_for_newline): If the default face was
10003 remapped, use the remapped face for the appended newline.
10004 (extend_face_to_end_of_line): Use the remapped default face for
10005 extending the face to the end of the line.
10006 (display_line): Call extend_face_to_end_of_line when the default
10007 face was remapped. (Bug#11068)
10009 2012-03-29 Eli Zaretskii <eliz@gnu.org>
10011 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
10013 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
10015 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
10017 2012-03-27 Glenn Morris <rgm@gnu.org>
10019 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
10022 2012-03-26 Kenichi Handa <handa@m17n.org>
10024 * dispextern.h (struct glyph): Fix previous change. Change the
10025 bit length of glyphless.ch to 25 (Bug#11082).
10027 2012-03-26 Chong Yidong <cyd@gnu.org>
10029 * keyboard.c (Vselection_inhibit_update_commands): New variable.
10030 (command_loop_1): Use it; inhibit selection update for
10031 handle-select-window too (Bug#8996).
10033 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
10035 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
10037 2012-03-25 Kenichi Handa <handa@m17n.org>
10039 * dispextern.h (struct glyph): Change the bit length of
10040 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
10042 2012-03-24 Eli Zaretskii <eliz@gnu.org>
10044 * s/ms-w32.h (tzname): Include time.h before redirecting to
10045 _tzname. Fixes the MSVC build. (Bug#9960)
10047 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
10049 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
10052 * xterm.c (XTread_socket): Only modify handling_signal if
10053 !SYNC_INPUT. (Bug#11080)
10055 2012-03-23 Eli Zaretskii <eliz@gnu.org>
10057 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
10058 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
10059 when fetching a multibyte character consumes more bytes than
10060 CHAR_BYTES returns, due to unification of CJK characters in
10061 string_char. (Bug#11073)
10063 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
10065 * process.c (wait_reading_process_output): Handle pty disconnect
10066 by refraining from sending oneself a SIGCHLD (bug#10933).
10068 2012-03-22 Chong Yidong <cyd@gnu.org>
10070 * dispextern.h (struct it): New member string_from_prefix_prop_p.
10072 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
10073 Mark string as coming from a prefix property.
10074 (handle_face_prop): Use default face for prefix strings (Bug#4281).
10075 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
10077 2012-03-21 Chong Yidong <cyd@gnu.org>
10079 * xfaces.c (Vface_remapping_alist): Doc fix.
10081 2012-03-20 Eli Zaretskii <eliz@gnu.org>
10083 * w32proc.c (Fw32_set_console_codepage)
10084 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
10087 2012-03-20 Chong Yidong <cyd@gnu.org>
10089 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
10090 to reflect default non-nil value of redisplay-dont-pause.
10092 2012-03-19 Kenichi Handa <handa@m17n.org>
10094 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
10095 it fit in a valid range (Bug#11003).
10097 2012-03-18 Eli Zaretskii <eliz@gnu.org>
10099 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
10100 that is not from display property, accept the row as a "cursor
10101 row" if one of the string's character has a non-nil `cursor'
10102 property. Fixes cursor positioning when there are newlines in
10103 overlay strings, e.g. in icomplete.el. (Bug#11035)
10105 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
10107 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
10109 2012-03-12 Chong Yidong <cyd@gnu.org>
10111 * eval.c (inhibit_lisp_code): Rename from
10112 inhibit_window_configuration_change_hook; move from window.c.
10114 * xfns.c (unwind_create_frame_1, Fx_create_frame):
10115 * window.c (run_window_configuration_change_hook)
10116 (syms_of_window): Callers changed.
10118 2012-03-11 Chong Yidong <cyd@gnu.org>
10120 * keymap.c (Fkey_description): Doc fix (Bug#9700).
10122 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
10124 2012-03-10 Chong Yidong <cyd@gnu.org>
10126 * frame.c (other_visible_frames): Don't assume the selected frame
10127 is visible (Bug#10955).
10129 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
10131 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
10133 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
10135 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
10136 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
10139 2012-03-03 Glenn Morris <rgm@gnu.org>
10141 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
10143 2012-03-02 Eli Zaretskii <eliz@gnu.org>
10145 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
10146 position past the first glyph_row that ends at ZV. (Bug#10902)
10147 (redisplay_window, next_element_from_string): Fix typos in
10149 (redisplay_window): Pass to move_it_vertically the margin in
10150 pixels, not in screen lines.
10152 2012-03-02 Glenn Morris <rgm@gnu.org>
10154 * buffer.c (buffer-list-update-hook): Doc fix.
10156 2012-02-29 Eli Zaretskii <eliz@gnu.org>
10158 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
10159 push_it before setting up the iterator for the first overlay
10160 string, even if we have an empty string loaded.
10161 (next_overlay_string): If there's an empty string on the iterator
10162 stack, pop the stack. (Bug#10903)
10164 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
10166 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
10167 Suggested by Stefan Monnier in
10168 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
10169 * alloc.c (widen_to_Lisp_Object): New static function.
10170 (mark_memory): Also mark Lisp_Objects by fetching pointer words
10171 and widening them to Lisp_Objects. This would work even if
10172 USE_LSB_TAG is defined and wide integers are used, which might
10173 happen in a future version of Emacs.
10175 2012-02-25 Chong Yidong <cyd@gnu.org>
10177 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
10180 * xselect.c (Fx_selection_exists_p): Doc fix.
10181 (x_clipboard_manager_save_all): Print an informative message
10182 before saving to clipboard manager.
10184 2012-02-24 Chong Yidong <cyd@gnu.org>
10186 * keyboard.c (process_special_events): Handle all X selection
10187 requests in kbd_buffer, not just the next one (Bug#8869).
10189 2012-02-23 Chong Yidong <cyd@gnu.org>
10191 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
10192 call when setting menu-bar-lines and tool-bar-lines parameters.
10193 (unwind_create_frame_1): New helper function.
10195 * window.c (inhibit_window_configuration_change_hook): New var.
10196 (run_window_configuration_change_hook): Obey it.
10197 (syms_of_window): Initialize it.
10199 2012-02-22 Chong Yidong <cyd@gnu.org>
10201 * xterm.c (x_draw_image_relief): Add missing type check for
10202 Vtool_bar_button_margin (Bug#10743).
10204 2012-02-21 Chong Yidong <cyd@gnu.org>
10206 * fileio.c (Vfile_name_handler_alist): Doc fix.
10208 * buffer.c (Fget_file_buffer): Protect against invalid file
10209 handler return value.
10211 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
10213 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
10214 when computing $valmask.
10216 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
10217 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
10218 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
10219 It's useless in that case, and it can cause problems on hosts
10220 that allocate halves of EMACS_INT values separately.
10221 Reported by Dan Horák. Diagnosed by Andreas Schwab in
10222 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
10223 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
10224 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
10225 it avoids undefined behavior on hosts where shifting right by more
10226 than the word width has undefined behavior.
10228 2012-02-19 Chong Yidong <cyd@gnu.org>
10230 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
10231 (Funhandled_file_name_directory, Ffile_name_as_directory)
10232 (Fdirectory_file_name, Fexpand_file_name)
10233 (Fsubstitute_in_file_name): Protect against invalid file handler
10234 return values (Bug#10845).
10236 2012-02-18 Eli Zaretskii <eliz@gnu.org>
10238 * .gdbinit (pitx): Fix incorrect references to fields of the
10241 2012-02-17 Chong Yidong <cyd@gnu.org>
10243 * syntax.c (Fscan_lists): Doc fix (Bug#10833).
10245 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>
10247 * image.c (MAX_IMAGE_SIZE): Increase from 6.0 to 10.0; see
10248 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
10250 2012-02-15 Chong Yidong <cyd@gnu.org>
10252 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
10253 marked as special. Also, starting docstrings with * is obsolete.
10255 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
10257 * gnutls.c (emacs_gnutls_write): Fix last change.
10259 2012-02-13 Lars Ingebrigtsen <larsi@gnus.org>
10261 * gnutls.c (emacs_gnutls_write): Set errno appropriately for
10264 2012-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
10266 * keymap.c (Fsingle_key_description): Handle char ranges.
10268 2012-02-12 Chong Yidong <cyd@gnu.org>
10270 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
10271 as that creates a dangerous corner case.

10836 2011-12-01 Andreas Schwab <schwab@linux-m68k.org>
10838 * keyboard.c (interrupt_signal): Don't call kill-emacs when

10841 2011-11-30 Eli Zaretskii <eliz@gnu.org>
10843 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
10844 verifies glyph row's hash code--we have just reallocated the

10924 (start_display): Don't move to the next line if the display should
10925 start at a newline that is part of a display vector or an overlay

11009 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
11010 is set, removing the need for VIRT_ADDRESS_VARIES.
11011 (PURE_P): Use a more-efficient implementation that needs just one
11012 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the

11018 consistency with the new puresize.h.
11019 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
11020 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

11026 (erase_phys_cursor, update_window_cursor, show_mouse_face)
11027 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
11028 behave as if the cursor position were at the window margin.
11030 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
11031 and the cursor position is out of bounds, behave as if the cursor
11032 position were at the window margin. (Bug#10075)
11034 2011-11-18 Chong Yidong <cyd@gnu.org>
11036 * window.c (Fwindow_combination_limit): Make first argument

11055 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
11057 * xdisp.c (row_hash): New function, body extracted from
11058 compute_line_metrics.
11059 (compute_line_metrics): Call row_hash, instead of computing the
11062 * dispnew.c (verify_row_hash): Call row_hash for computing the
11063 hash code of a row, instead of duplicating code from xdisp.c.
11065 * dispextern.h (row_hash): Add prototype.
11067 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
11069 * frame.c (delete_frame): Don't delete the terminal when the last

11118 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
11119 with user-defined heap size. Bump the default size of the temacs

11123 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
11124 current_matrix and desired_matrix. (Bug#9990)
11125 (verify_row_hash) [XASSERTS]: New function.

11170 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
11172 Avoid some portability problems by eschewing 'extern inline' functions.
11173 The trivial performance wins aren't worth the portability hassles; see
11174 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
11176 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

11225 This is also needed for porting to any host where GC_MARK_STACK is
11226 not GC_MAKE_GCPROS_NOOPS.
11227 (which_symbols): Use it.
11229 2011-11-07 Kenichi Handa <handa@m17n.org>

11242 * xmenu.c (cleanup_widget_value_tree): New function.
11243 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
11244 calling free_menubar_widget_value_tree directly (Bug#9830).
11246 2011-11-06 Paul Eggert <eggert@cs.ucla.edu>
11248 Fix some portability problems with 'inline'.
11249 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
11250 (window_box_width, window_box_left, window_box_left_offset)
11251 (window_box_right, window_box_right_offset): Declare extern.
11252 Otherwise, these inline functions do not conform to C99 and
11253 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
11254 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
11255 * intervals.c (adjust_intervals_for_insertion)
11256 (adjust_intervals_for_deletion): Now extern, because otherwise the
11257 extern inline functions 'offset_intervals' couldn't refer to it.
11258 (static_offset_intervals): Remove.
11259 (offset_intervals): Rewrite using the old contents of
11260 static_offset_intervals. The old version didn't conform to C99
11261 because an extern inline function contained a reference to an
11262 identifier with static linkage.
11264 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
11266 * keyboard.c (interrupt_signal): Don't call kill-emacs while in

11284 (Fwindow_vscroll): Doc fix.
11285 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
11286 argument, since it makes no sense to pass a live window and for
11287 consistency with window-child.

11317 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).
11318 Initialize image_cache_refcount if GLYPH_DEBUG (Bug#9943).
11319 Move terminal->reference_count++ just before making the frame official

11328 official. Move initialization of image_cache_refcount and
11329 dpyinfo_refcount before calling init_frame_faces (Bug#9943).

11369 previous/next-single-property-change returns nil, treat that as
11370 the beginning or the end of the buffer. (Bug#9955)
11372 2011-11-04 Jan Djärv <jan.h.d@swipnet.se>
11374 * gtkutil.c (xg_make_tool_item): Add callbacks if one of wimage or

11497 (w32font_open_internal, compute_metrics):
11498 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
11499 instead of calling the "wide" APIs directly.
11501 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
11503 * w32.h (syms_of_w32font): Add prototype.
11505 2011-10-27 Juanma Barranquero <lekktu@gmail.com>

11512 2011-10-27 Chong Yidong <cyd@gnu.org>
11514 * process.c (make_process): Set gnutls_state to NULL.
11516 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
11517 non-NULL, regardless of GNUTLS_INITSTAGE.
11518 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal

11566 (bidi_resolve_weak): Don't enter the expensive loop if the current
11567 position is before next_en_pos. Record the bidi type of the first
11568 non-ET, non-BN character we find, in addition to its position.
11569 (bidi_level_of_next_char): Invalidate next_en_type when
11570 next_en_pos is over-stepped.
11572 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
11574 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
11575 * editfns.c: Rewrite current-time-zone so that it invokes
11576 the equivalent of (format-time-string "%Z") to get the time zone name.
11577 This fixes a bug when the time zone name contains characters that
11578 need converting from the system time locale to Emacs internal format.
11579 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
11580 that patch fixed format-time-string to do the conversion, but
11581 I forgot to fix current-time-zone.
11582 (format_time_string): New function, containing most of
11583 what Fformat_time_string used to contain.
11584 (Fformat_time_string): Rewrite in terms of format_time_string.
11585 This doesn't change this function's behavior.
11586 (current-time-zone): Rewrite to use format_time_string.
11587 This fixes the bug reported by Michael Schierl in
11588 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
11589 Jason Rumney's 2007-06-07 change worked around this bug, but
11591 * systime.h (tzname, timezone): Remove no-longer-used declarations.
11593 2011-10-19 Eli Zaretskii <eliz@gnu.org>
11595 * xdisp.c (start_display): If the character at POS is displayed
11596 via a display vector, reset IT->current.dpvec_index to zero.
11597 (try_window_reusing_current_matrix): If a line ends in a display
11598 vector or the next line starts in a display vector, continue
11599 redrawing the window even though the character position of
11600 start_row was reached.
11603 2011-10-18 Chong Yidong <cyd@gnu.org>
11605 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
11606 with nobreak-char-display too.
11608 2011-10-18 Eli Zaretskii <eliz@gnu.org>
11610 Fix part 3 of bug#9771.
11611 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
11612 (bidi_resolve_neutral): Don't enter the expensive loop looking for
11613 non-neutral characters if the current character is a paragraph
11614 separator (a.k.a. Newline). This avoids running the same
11615 expensive loop twice, once when we consume the preceding newline
11616 and the other time when the line actually needs to be displayed.
11617 Avoid the loop when we see neutrals on the base embedding level
11618 following a character whose directionality is the same as the
11619 paragraph's. This avoids running the expensive loop when a line
11620 ends in a long sequence of neutrals, like control characters.
11621 Add assertion against STRONG_AL type. Slightly rearrange code
11622 that determines the type of a neutral given the first non-neutral
11624 (bidi_level_of_next_char): Set next_en_pos to zero when
11625 invalidating its info.
11627 2011-10-17 Eli Zaretskii <eliz@gnu.org>
11629 * xdisp.c (push_display_prop): Determine whether to record string
11630 or buffer position by IT->string, not by IT->method. Allow
11631 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
11632 (move_it_vertically_backward): Don't look for character position
11633 immediately after the newline when in a continuation line.
11636 2011-10-15 Martin Rudalics <rudalics@gmx.at>
11638 * window.c (coordinates_in_window): Rewrite and delabelize
11639 vertical border check. (Bug#5357) (Bug#9618)
11641 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
11643 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
11644 errors in XSetWindowBorder (bug#9310).
11646 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
11648 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
11649 avoid crash when xmalloc overrun checking is enabled.
11651 2011-10-13 Eli Zaretskii <eliz@gnu.org>
11653 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
11654 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
11655 cursor motion with <left> and <right> arrow keys.
11657 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
11658 some callers set that themselves.
11660 2011-10-12 Eli Zaretskii <eliz@gnu.org>
11662 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
11663 display string and the previous row comes from the same string and
11664 is empty. (Bug#9739) (Bug#9738)
11666 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
11668 * doc.c (get_doc_string): Encode file name (bug#9735).
11670 2011-10-12 Eli Zaretskii <eliz@gnu.org>
11672 * bidi.c (bidi_level_of_next_char):
11673 * xdisp.c (get_visually_first_element): Remove old incorrect
11674 comments regarding the Unicode Line Separator character.
11676 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
11678 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
11680 * alloc.c (Fgc_status): Do not access beyond zombies array
11681 boundary if nzombies > MAX_ZOMBIES.
11682 * alloc.c (dump_zombies): Add missing format specifier.
11684 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
11686 * xdisp.c (set_cursor_from_row): Simplify conditionals,
11687 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
11689 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
11690 Some packages use them to denote characters with modifiers.
11692 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
11694 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
11695 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
11696 matching a pp-number. Rename parameter var to var1.
11698 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
11700 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
11702 2011-10-08 Glenn Morris <rgm@gnu.org>
11704 * callint.c (Fcall_interactively): Give a more explicit error for the
11705 'c' case with a non-character input. (Bug#8479)
11707 2011-10-08 Eli Zaretskii <eliz@gnu.org>
11709 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
11711 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
11712 lines that are hscrolled on the left.
11714 * dispnew.c (buffer_posn_from_coords): Account for a possible
11715 presence of header-line. (Bug#4426)
11717 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
11719 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
11720 Don't advertise functionality which we discourage or doesn't work.
11722 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
11724 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
11725 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
11726 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
11727 this makes Emacs dump core during garbage collection on rare
11728 occasions. sizeof is obviously inferior to offsetof here, so
11729 stick with offsetof.
11730 (GC_POINTER_ALIGNMENT): New macro.
11731 (mark_memory): Omit 3rd (offset) arg; caller changed.
11732 Don't assume EMACS_INT alignment is the same as pointer alignment.
11734 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
11736 * keyboard.c (read_key_sequence_remapped): New var.
11737 (read_key_sequence): Compute remapping in the right buffer.
11738 (command_loop_1): Use read_key_sequence's remapping directly.
11740 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
11742 * dired.c (file_name_completion): Don't expand file name.
11743 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
11744 before checking file name handler.
11746 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
11747 they've been requested explicitly (bug#9591).
11749 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
11751 * keymap.c (Fsingle_key_description): Use make_specified_string
11752 instead of build_string to build string from push_key_description.
11755 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
11757 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
11758 This fixes a Y2038 bug on 64-bit hosts.
11759 * buffer.c (reset_buffer):
11760 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
11761 (Fclear_buffer_auto_save_failure):
11762 Use 0, not -1, to represent an unset failure time, since time_t
11763 might not be signed.
11765 Remove dependency on glibc malloc internals.
11766 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11767 Move back here from lisp.h, but with their new implementations.
11768 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
11769 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
11770 * charset.c (charset_table_init): New static var.
11771 (syms_of_charset): Use it instead of xmalloc. This removes a
11772 dependency on glibc malloc internals. See Eli Zaretskii's comment in
11773 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
11774 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11775 Move back to alloc.c.
11776 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
11777 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
11779 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
11781 * nsterm.m (windowDidResize): Call x_set_window_size only when
11782 ns_in_resize is true. Otherwise set pixelwidth/height and
11783 call change_frame_size (Bug#9628).
11785 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
11787 Port --enable-checking=all to Fedora 14 x86-64.
11788 * charset.c (syms_of_charset): Also account for glibc malloc's
11789 internal overhead when calculating the initial malloc maximum.
11791 Port --enable-checking=all to Fedora 14 x86.
11792 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11794 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
11795 (overrun_check_realloc, overrun_check_free):
11796 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
11797 That way, xmalloc returns a properly-aligned pointer even if
11798 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
11799 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
11800 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
11801 into account when calculating the initial malloc maximum.
11802 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11803 Move here from alloc.c, so that charset.c can use it too.
11804 Properly align; the old code wasn't right for common 32-bit hosts
11805 when configured with --enable-checking=all.
11806 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
11807 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
11809 2011-09-29 Eli Zaretskii <eliz@gnu.org>
11811 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
11814 2011-09-28 Eli Zaretskii <eliz@gnu.org>
11816 * xdisp.c (compute_display_string_end): If there's no display
11817 string at CHARPOS, return -1.
11819 * bidi.c (bidi_fetch_char): When compute_display_string_end
11820 returns a negative value, treat the character as a normal
11821 character not covered by a display string. (Bug#9624)
11823 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
11825 * lread.c (Fread_from_string): Fix typo in docstring.
11827 2011-09-27 Eli Zaretskii <eliz@gnu.org>
11829 * xdisp.c (handle_invisible_prop): If invisible text ends on a
11830 newline, reseat the iterator instead of bidi-iterating there one
11831 character at a time. (Bug#9610)
11832 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
11833 TO_CHARPOS if the bidi iterator is at base embedding level.
11835 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
11837 * lread.c (readevalloop): Use correct code for NBSP.
11838 (read1): Likewise. (Bug#9608)
11840 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
11842 * dbusbind.c (Fdbus_register_signal): When service is not
11843 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
11845 2011-09-25 Glenn Morris <rgm@gnu.org>
11847 * buffer.c (truncate-lines): Doc fix.
11849 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
11851 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
11852 (Fset_window_next_buffers): Doc fix.
11854 2011-09-24 Glenn Morris <rgm@gnu.org>
11856 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
11858 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
11860 Fix minor problems found by static checking.
11861 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
11862 * indent.c (Fvertical_motion): Fix == vs = typo.
11864 2011-09-24 Eli Zaretskii <eliz@gnu.org>
11866 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
11867 Default value is now t. Doc fix.
11869 * indent.c (Fvertical_motion): Compute and apply the overshoot
11870 logic when moving up, not only when moving down. Fix the
11871 confusing name and values of the it_overshoot_expected variable;
11872 logic changes accordingly. (Bug#9254) (Bug#9549)
11874 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
11875 CHARPOS is covered by a display string which includes newlines.
11876 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
11877 is covered by a display string with embedded newlines.
11879 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
11881 * dbusbind.c (Fdbus_register_signal): Add match rule to
11882 Vdbus_registered_objects_table. (Bug#9581)
11883 (Fdbus_register_method, Vdbus_registered_objects_table):
11886 2011-09-24 Jim Meyering <meyering@redhat.com>
11888 do not ignore write error for any output size
11889 The previous change was incomplete.
11890 While it makes emacs --batch detect the vast majority of stdout
11891 write failures, errors were still ignored whenever the output size is
11892 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
11893 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
11894 && echo FAIL: ignored write error
11895 FAIL: ignored write error
11896 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
11897 && echo FAIL: ignored write error
11898 FAIL: ignored write error
11899 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
11901 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
11903 * emacs.c (Fkill_emacs): In noninteractive mode exit
11904 non-successfully if a write error occurred on stdout. (Bug#9574)
11906 2011-09-21 Eli Zaretskii <eliz@gnu.org>
11908 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
11911 * dispextern.h (struct it): Update the comment documenting what
11914 2011-09-20 Eli Zaretskii <eliz@gnu.org>
11916 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
11917 a display string, extend search for cursor position to end of row.
11918 (find_row_edges): If the row ends in a newline from a display
11919 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
11920 Handle the case of a display string with multiple newlines.
11921 (Fcurrent_bidi_paragraph_direction): Fix search for previous
11922 non-empty line. Fixes confusing cursor motion with arrow keys at
11923 the beginning of a line that starts with whitespace.
11925 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
11927 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
11930 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
11932 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
11933 boolean (Bug#9154).
11935 2011-09-18 Eli Zaretskii <eliz@gnu.org>
11937 * xdisp.c (display_line): Record maximum and minimum buffer
11938 positions even if no glyphs were produced (e.g., by a zero-width
11939 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
11940 buffer positions that will be removed from the glyph row because
11942 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
11943 column is beyond frame width: don't subtract 1 "pixel" when
11944 computing width of the stretch.
11945 (reseat_at_next_visible_line_start): Undo the change made on
11946 2011-09-17 that saved paragraph information and restored it after
11947 the call to `reseat'. (Bug#9545)
11949 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11951 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
11952 and turn window cursor on if cleared (Bug#9415).
11954 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
11956 * search.c (boyer_moore): Take unibyte characters from pattern
11957 literally. (Bug#9458)
11959 2011-09-18 Eli Zaretskii <eliz@gnu.org>
11961 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
11963 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
11965 Fix minor problem found by static checking.
11966 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
11967 initialized, to pacify gcc -Wuninitialized.
11969 * fileio.c: Report proper errno when syscall falls.
11970 (Finsert_file_contents): Save and restore errno,
11971 so that report_file_error outputs the correct diagnostic.
11972 (Fwrite_region) [CLASH_DETECTION]: Likewise.
11974 2011-09-18 Eli Zaretskii <eliz@gnu.org>
11976 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
11978 2011-09-17 Eli Zaretskii <eliz@gnu.org>
11980 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
11981 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
11983 2011-09-17 Eli Zaretskii <eliz@gnu.org>
11985 * xdisp.c (reseat_at_next_visible_line_start): Keep information
11986 about the current paragraph and restore it after the call to reseat.
11988 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
11989 (bidi_find_paragraph_start): Search back for paragraph beginning
11990 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
11991 (bidi_move_to_visually_next): Only trigger paragraph-related
11992 computations when the last character is a newline or at EOB, not
11993 just any NEUTRAL_B. (Bug#9470)
11995 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
11996 truncated lines if point is covered by a display string. (Bug#9524)
11998 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
12000 * xselect.c: Relax test for outgoing X longs (Bug#9498).
12001 (cons_to_x_long): New function.
12002 (lisp_data_to_selection_data): Use it. Correct the test for
12003 short-versus-long data; it was negated. Break out of vector
12004 loop, for efficiency, when a long datum is discovered.
12006 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
12008 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
12010 2011-09-16 Eli Zaretskii <eliz@gnu.org>
12012 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
12013 GCC PR/17406) by declaring this function with external scope.
12015 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
12017 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
12018 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
12020 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
12022 * editfns.c (Fformat): Correctly handle text properties on "%%".
12024 2011-09-15 Eli Zaretskii <eliz@gnu.org>
12026 * xterm.c (x_draw_composite_glyph_string_foreground):
12027 * w32term.c (x_draw_composite_glyph_string_foreground):
12028 * term.c (encode_terminal_code):
12029 * composite.c (composition_update_it, get_composition_id):
12030 * xdisp.c (get_next_display_element)
12031 (fill_composite_glyph_string): Add comments about special meaning
12032 of TAB characters in a composition.
12034 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
12036 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
12037 This occurs when processing a multibyte format.
12038 Problem reported by Wolfgang Jenker.
12040 2011-09-15 Johan Bockgård <bojohan@gnu.org>
12042 * xdisp.c (try_cursor_movement): Only check for exact match if
12043 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
12045 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
12047 Remove unused external symbols.
12048 * dispextern.h (calc_pixel_width_or_height): Remove decl.
12049 * xdisp.c (calc_pixel_width_or_height): Now static.
12050 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
12051 * indent.c (check_display_width):
12052 * w32term.c: Fix comment to match code.
12053 * xterm.c, xterm.h (x_catching_errors): Remove.
12055 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
12057 * xselect.c: Use signed conversions more consistently (Bug#9498).
12058 (selection_data_to_lisp_data): Assume incoming selection data are
12059 signed integers, not unsigned. This is to be consistent with
12060 outgoing selection data, which was modified to use signed integers
12061 in as part of the fix to Bug#9196 in response to Jan D.'s comment
12062 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
12063 expects long, not unsigned long.
12065 2011-09-14 Eli Zaretskii <eliz@gnu.org>
12067 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
12068 computation of loop end. Reported by Johan Bockgård
12071 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
12073 * frame.c (Fother_visible_frames_p): Function deleted.
12075 2011-09-12 Eli Zaretskii <eliz@gnu.org>
12077 * indent.c (compute_motion): Process display vector front to back
12078 rather than the other way around. (Bug#2496)
12080 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
12082 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
12084 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
12086 * minibuf.c (Fread_from_minibuffer): Doc fix.
12088 2011-09-11 Eli Zaretskii <eliz@gnu.org>
12090 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
12091 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
12093 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
12095 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
12096 value for non-existent files.
12098 2011-09-11 Eli Zaretskii <eliz@gnu.org>
12100 * fileio.c (Finsert_file_contents): If the file cannot be opened,
12101 set its "size" to -1. This will set the modtime_size field of
12102 the corresponding buffer to -1, which is what
12103 verify-visited-file-modtime expects for files that do not exist.
12106 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
12108 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
12110 * lisp.h: ... from here. push_key_description is no longer
12111 defined in keyboard.c, so its declaration should not be in
12112 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
12113 logically belongs with push_key_description.
12115 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
12117 * buffer.h: Include <sys/types.h> instead of <time.h>.
12118 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
12119 Problem reported by Herbert J. Skuhra.

12123 * xml.c (parse_region): Make the parsing work for
12124 non-comment-starting XML files again (bug#9144).
12126 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
12128 * image.c (gif_load): Fix calculation of bottom and right corner.
12131 2011-09-10 Eli Zaretskii <eliz@gnu.org>
12133 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
12134 redisplay in small windows.
12136 2011-09-09 Eli Zaretskii <eliz@gnu.org>
12138 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
12140 2011-09-08 Martin Rudalics <rudalics@gmx.at>
12142 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
12143 Operate on live windows only.
12145 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
12147 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
12149 2011-09-07 Eli Zaretskii <eliz@gnu.org>
12151 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
12152 only under bidi iteration.
12154 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
12156 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
12158 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
12160 isnan: Fix porting problem to Solaris 10 with bundled gcc.
12161 Without this fix, the command to link temacs failed due to an
12162 undefined symbol __builtin_isnan. This is because
12163 /usr/include/iso/math_c99.h #defines isnan(x) to
12164 __builtin_isnan(x), but the bundled gcc, which identifies itself
12165 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
12167 * floatfns.c (isnan): #undef, and then #define to a clone of
12169 (Fisnan): Always define, since it's always available now.
12170 (syms_of_floatfns): Always define isnan at the Lisp level.
12172 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
12174 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
12176 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
12178 * fileio.c: Fix bugs with large file offsets (Bug#9428).
12179 The previous code assumed that file offsets (off_t values) fit in
12180 EMACS_INT variables, which is not true on typical 32-bit hosts.
12181 The code messed up by falsely reporting buffer overflow in cases
12182 such as (insert-file-contents "big" nil 1 2) into an empty buffer
12183 when "big" contains more than 2**29 bytes, even though this
12184 inserts just one byte and does not overflow the buffer.
12185 (Finsert_file_contents): Store file offsets as off_t
12186 values, not as EMACS_INT values. Check for overflow when
12187 converting between EMACS_INT and off_t. When checking for
12188 buffer overflow or for overlap, take the offsets into account.
12189 Don't use EMACS_INT for small values where int suffices.
12190 When checking for overlap, fix a typo: ZV was used where
12191 ZV_BYTE was intended.
12192 (Fwrite_region): Don't assume off_t fits into 'long'.
12193 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
12195 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
12197 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
12199 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
12201 sprintf-related integer and memory overflow issues (Bug#9412).
12203 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
12204 (esprintf, exprintf, evxprintf): New functions.
12205 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
12206 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
12207 (modify_event_symbol): Do not assume that the length of
12208 name_alist_or_stem is safe to alloca and fits in int.
12209 (Fexecute_extended_command): Likewise for function name and binding.
12210 (Frecursion_depth): Wrap around reliably on integer overflow.
12211 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
12212 since some callers pass EMACS_INT values.
12213 (Fsingle_key_description): Don't crash if symbol name contains more
12214 than MAX_ALLOCA bytes.
12215 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
12216 (get_minibuffer): Arg is now EMACS_INT, not int.
12217 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
12218 (esprintf, exprintf, evxprintf): New decls.
12219 * window.h (command_loop_level, minibuf_level): Reflect API changes.
12221 * dbusbind.c (signature_cat): New function.
12222 (xd_signature, Fdbus_register_signal):
12223 Do not overrun buffer; instead, report string overflow.
12225 * dispnew.c (add_window_display_history): Don't overrun buffer.
12226 Truncate instead; this is OK since it's just a log.
12228 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
12229 even if the time zone offset is outlandishly large.
12230 Don't mishandle offset == INT_MIN.
12232 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
12233 when creating daemon; the previous buffer-overflow check was incorrect.
12235 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
12236 which has the guts of the old verror function.
12238 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
12239 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
12241 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
12242 (font_unparse_xlfd): Don't blindly alloca long strings.
12243 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
12244 fits in int, when using sprintf. Use single snprintf to count
12245 length of string rather than counting it via multiple sprintfs;
12246 that's simpler and more reliable.
12247 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
12248 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
12249 sprintf, in case result does not fit in int.
12251 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
12252 (fontset_from_font): Print it.
12254 * frame.c (tty_frame_count): Now printmax_t, not int.
12255 (make_terminal_frame, set_term_frame_name): Print it.
12256 (x_report_frame_params): In X, window IDs are unsigned long,
12257 not signed long, so print them as unsigned.
12258 (validate_x_resource_name): Check for implausibly long names,
12259 and don't assume name length fits in 'int'.
12260 (x_get_resource_string): Don't blindly alloca invocation name;
12261 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
12264 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
12265 (xg_check_special_colors, xg_set_geometry):
12266 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
12268 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
12269 Use esprintf, not sprintf, in case result does not fit in int.
12271 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
12272 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
12273 it as a large positive number.
12274 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
12275 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
12277 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
12278 in case result does not fit in int.
12280 * print.c (float_to_string): Detect width overflow more reliably.
12281 (print_object): Make sprintf buffer a bit bigger, to avoid potential
12282 buffer overrun. Don't assume list length fits in 'int'. Treat
12283 print length of 0 as 0, not as infinity; to be consistent with other
12284 uses of print length in this function. Don't overflow print length
12285 index. Don't assume hash table size fits in 'long', or that
12286 vectorlike size fits in 'unsigned long'.
12288 * process.c (make_process): Use printmax_t, not int, to format
12289 process-name gensyms.
12291 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
12293 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
12294 to avoid potential buffer overrun.
12296 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
12297 if X resource line is longer than 512 bytes.
12299 * xfns.c (x_window): Make sprintf buffer a bit bigger
12300 to avoid potential buffer overrun.
12302 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
12304 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
12306 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
12308 Integer overflow fixes for scrolling, etc.
12309 Without these, Emacs silently mishandles large integers sometimes.
12310 For example, "C-u 4294967297 M-x recenter" was treated as if
12311 it were "C-u 1 M-x recenter" on a typical 64-bit host.
12313 * xdisp.c (try_window_id): Check Emacs fixnum range before
12314 converting to 'int'.
12316 * window.c (window_scroll_line_based, Frecenter):
12317 Check that an Emacs fixnum is in range before assigning it to 'int'.
12318 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
12319 values converted from Emacs fixnums.
12320 (Frecenter): Don't wrap around a line count if it is out of 'int'
12321 range; instead, treat it as an extreme value.
12322 (Fset_window_configuration, compare_window_configurations):
12323 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
12325 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
12326 that can exceed INT_MAX. Check that EMACS_INT value is in range
12327 before assigning it to the (possibly-narrower) index.
12328 (match_limit): Don't assume that a fixnum can fit in 'int'.
12330 * print.c (print_object): Use ptrdiff_t, not int, for index that can
12333 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
12334 (Fvertical_motion): Don't wrap around LINES values that don't fit
12335 in 'int'. Instead, treat them as extreme values. This is good
12336 enough for windows, which can't have more than INT_MAX lines anyway.
12338 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
12340 * Require libxml/parser.h to avoid compilation warning.
12342 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
12344 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
12345 since this reportedly can destroy thread storage.
12347 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
12349 * syntax.c (find_defun_start): Update all cache variables if
12350 exiting early (Bug#9401).
12352 2011-08-30 Eli Zaretskii <eliz@gnu.org>
12354 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
12356 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
12357 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
12358 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
12360 * term.c (tty_append_glyph): New function.
12361 (produce_stretch_glyph): Static function and its prototype deleted.
12363 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
12366 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
12368 * image.c (parse_image_spec): Check for nonnegative, not for positive,
12369 when checking :margin (Bug#9390).
12370 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
12371 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
12372 so that the name doesn't mislead. All uses changed.
12374 2011-08-28 Johan Bockgård <bojohan@gnu.org>
12376 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
12379 2011-08-27 Eli Zaretskii <eliz@gnu.org>
12381 * xdisp.c (move_it_to): Don't bail out early when reaching
12382 position beyond to_charpos, if we are scanning backwards.
12383 (move_it_vertically_backward): When DY == 0, make sure we get to
12384 the first character in the line after the newline.
12386 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
12388 * ccl.c: Improve and simplify overflow checking (Bug#9196).
12389 (ccl_driver): Do not generate an out-of-range pointer.
12390 (Fccl_execute_on_string): Remove unnecessary check for
12391 integer overflow, noted by Stefan Monnier in
12392 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
12393 Remove a FIXME that didn't need fixing.
12394 Simplify the newly-introduced buffer reallocation code.
12396 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
12398 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
12400 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
12402 Integer and memory overflow issues (Bug#9196).
12404 * doc.c (get_doc_string): Rework so that
12405 get_doc_string_buffer_size is the actual buffer size, rather than
12406 being 1 less than the actual buffer size; this makes xpalloc more
12409 * image.c (x_allocate_bitmap_record, cache_image):
12410 * xselect.c (Fx_register_dnd_atom):
12411 Simplify previous changes by using xpalloc.
12413 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
12414 since either will do and ptrdiff_t is convenient with xpalloc.
12416 * charset.c (charset_table_size)
12417 (struct charset_sort_data.priority): Now ptrdiff_t.
12418 (charset_compare): Don't overflow if priorities differ greatly.
12419 (Fsort_charsets): Don't assume list length fits in int.
12420 Check for size-calculation overflow when allocating sort data.
12421 (syms_of_charset): Allocate an initial charset table that is
12422 just under 64 KiB, to avoid problems with glibc malloc and mmap.
12424 * cmds.c (internal_self_insert): Check for size-calculation overflow.
12426 * composite.h (struct composition.glyph_len): Now int, not unsigned.
12427 The actual value is always <= INT_MAX, and leaving it unsigned made
12428 overflow checking harder.
12430 * dispextern.h (struct glyph_matrix.rows_allocated)
12431 (struct face_cache.size): Now ptrdiff_t, for convenience in use
12432 with xpalloc. The values are still always <= INT_MAX.
12434 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
12436 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
12437 (SAFE_NALLOCA): New macro.
12439 * region-cache.c (struct boundary.pos, find_cache_boundary)
12440 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
12441 (set_cache_region, invalidate_region_cache)
12442 (revalidate_region_cache, know_region_cache, region_cache_forward)
12443 (region_cache_backward, pp_cache):
12444 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
12445 so that ptrdiff_t * can be passed to xpalloc.
12446 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
12447 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
12448 (pp_cache): Don't assume cache_len fits in int.
12449 * region-cache.h: Adjust extern decls to match.
12451 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
12452 EMACS_INT, since either will do, for xpalloc.
12454 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
12455 (xnmalloc, xnrealloc, xpalloc): New functions.
12457 * bidi.c (bidi_shelve_header_size): New constant.
12458 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
12459 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
12461 * bidi.c (bidi_cache_shrink):
12462 * buffer.c (overlays_at, overlays_in, record_overlay_string)
12464 Don't update size of array until after memory allocation succeeds,
12465 because xmalloc/xrealloc may not return.
12466 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
12467 now that we have proper integer overflow checking.
12468 (record_overlay_string, overlay_strings): Catch overflows when
12469 calculating size of overlay_str_buf.
12471 * callproc.c (Fcall_process): Check for size overflow when
12472 calculating size of args2.
12473 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
12474 Normally we prefer signed values, but sticking with ptrdiff_t would
12475 require adding more-complicated checks.
12477 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
12478 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
12479 Redo buffer-overflow calculations to avoid integer overflow.
12480 Add a FIXME comment where memory seems to be over-allocated.
12482 * character.c (Fstring): Check for size-calculation overflow.
12484 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
12485 unnecessary integer overflow. Check for size overflow.
12486 (encode_coding_object): Don't update size until xmalloc succeeds.
12488 * composite.c (get_composition_id): Check for overflow in glyph
12489 length calculations.
12491 Integer and memory overflow fixes for display code.
12492 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
12493 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
12494 (scrolling_window): Check for overflow in size calculations.
12495 (line_draw_cost, realloc_glyph_pool, add_row_entry):
12496 Don't assume glyph table len fits in int.
12497 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
12498 (row_table_size): Now ptrdiff_t, not int.
12499 (scrolling_window): Avoid overflow in size calculations.
12500 Don't update size until allocation succeeds.
12501 * fns.c (concat): Check for overflow in size calculations.
12502 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
12503 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
12504 (NEXT_ALMOST_PRIME_LIMIT): New constant.
12506 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
12507 (get_doc_string): Check for size calculation overflow.
12508 Don't update size until allocation succeeds.
12509 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
12510 EMACS_INT, where ptrdiff_t will do.
12511 (Fsubstitute_command_keys): Check for string overflow.
12513 * editfns.c (set_time_zone_rule): Don't assume environment length
12515 (message_length): Now ptrdiff_t, not int.
12516 (Fmessage_box): Don't update size until allocation succeeds.
12517 Don't assume message length fits in int.
12518 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
12520 * emacs.c (main): Do not reallocate argv, since there is a null at
12521 the end that can be overwritten, and this way there's no need to
12522 worry about size-calculation overflow.
12523 (sort_args): Check for size-calculation overflow.
12525 * eval.c (init_eval_once, grow_specpdl): Don't update size until
12527 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
12529 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
12530 (x_set_scroll_bar_width, x_figure_window_size):
12531 Check for integer overflow.
12532 (x_set_alpha): Do not assume XINT fits in int.
12534 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
12535 This is for the members text_lines, text_cols, total_lines, total_cols,
12536 where the system imposes an 'int' limit.
12538 * fringe.c (Fdefine_fringe_bitmap):
12539 Don't update size until alloc works.
12541 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
12542 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
12544 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
12545 Check for size-calculation overflow.
12546 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
12547 do, as we prefer signed integers.
12548 (id_to_widget.max_size, id_to_widget.used)
12549 (xg_store_widget_in_map, xg_remove_widget_from_map)
12550 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
12551 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
12552 Use and return ptrdiff_t, not int.
12553 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
12554 * gtkutil.h: Change prototypes to match the above.
12556 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
12557 are duplicate now that they've been promoted to lisp.h.
12558 (x_allocate_bitmap_record, x_alloc_image_color)
12559 (make_image_cache, cache_image, xpm_load):
12560 Don't update size until alloc is done.
12561 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
12563 Check for size calculation overflow.
12564 (ct_colors_allocated_max): New constant.
12565 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid
12568 * keyboard.c (read_char, menu_bar_items, tool_bar_items)
12569 (read_char_x_menu_prompt, read_char_minibuf_menu_width)

12603 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
12604 for command line length. Do not attempt to address one before the
12605 beginning of an array, as that's not portable.

12635 Check for size calculation overflow.
12636 (cache_face): Treat size calculation overflows as if they were
12637 memory exhaustion (the usual treatment), rather than aborting.
12639 * xfns.c (x_encode_text, x_set_name_internal)
12640 (Fx_change_window_property): Use ptrdiff_t, not int, to count
12641 sizes, since they can exceed INT_MAX in size. Check for size
12642 calculation overflow.
12644 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
12645 (xg_select): Check for size calculation overflow.
12646 Don't update size until alloc done.
12648 * xrdb.c (get_environ_db): Don't assume path length fits in int,
12649 as sprintf is limited to int lengths.
12651 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
12652 (X_LONG_MIN): New macros.
12653 Use them to make the following changes clearer.
12654 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
12655 This change doesn't affect the value now, but it may help remind
12656 future maintainers not to raise the value too much later.
12657 (SELECTION_QUANTUM): Remove, replacing with ...
12658 (selection_quantum): ... new function, which avoids overflow.
12660 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
12661 assumption that selection length fits in 'int'.
12662 (x_reply_selection_request, x_handle_selection_request)
12663 (x_get_window_property, receive_incremental_selection)

12678 Don't store size until memory allocation succeeds.
12679 (x_get_window_property): Plug memory leak on memory exhaustion.
12680 Don't double-block input; malloc is safe here. Don't assume 2**34
12681 - 4 fits in unsigned long. Add an xassert to check
12682 XGetWindowProperty overflow. Be more careful about overflow
12683 calculations, and distinguish size from memory overflow better.
12684 (receive_incremental_selection): When tracing, don't assume
12685 unsigned int is less than INT_MAX.
12686 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory

12690 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
12691 result parameters unless successful. Rely on cons_to_unsigned
12692 to report problems with elements; the old code wasn't right anyway.
12693 (x_check_property_data): Check for int overflow; we cannot use
12694 a wider type due to X limits.
12695 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

12727 * lisp.h (hash_lookup, hash_put):
12728 * minibuf.c (Ftest_completion):
12729 Use ptrdiff_t for hash table indexes, not int (which is too
12730 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
12731 32-bit --with-wide-int hosts).
12733 * charset.c (Fdefine_charset_internal): Check for integer overflow.
12734 Add a FIXME comment about memory leaks.

12742 with outlandish widths.
12743 * character.h (sanitize_tab_width): Rename from sanitize_width,
12744 now that we have two such functions. All uses changed.

12762 * xterm.c: Don't go over XClientMessageEvent limit.
12763 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
12764 (x_send_scroll_bar_event): Likewise. Check that the size does not
12765 exceed limits imposed by XClientMessageEvent, as well as the usual
12766 ptrdiff_t and size_t limits.
12768 * keyboard.c: Overflow, signedness and related fixes.
12769 (make_lispy_movement): Use same integer type in forward decl
12770 that is used in the definition.
12771 (read_key_sequence, keyremap_step):
12772 Change bufsize argument back to int, undoing my 2011-03-30 change.
12773 We prefer signed types, and int is wide enough here.
12774 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
12775 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
12776 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
12777 length, not size_t. Use ptrdiff_t for index, not int.
12778 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
12779 possibility of integer overflow.
12781 Overflow, signedness and related fixes for images.

12807 Prefer int to unsigned where either will do.
12808 (tiff_handler): New function, combining the cores of the
12809 old tiff_error_handler and tiff_warning_handler.
12810 This function is rewritten to use vsnprintf and thereby avoid
12811 stack buffer overflows. It uses only the features of vsnprintf
12812 that are common to both POSIX and native Microsoft.
12813 (tiff_error_handler, tiff_warning_handler): Use it.
12814 (tiff_load, gif_load, imagemagick_load_image):
12815 Don't assume :index value fits in 'int'.
12816 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
12817 (imagemagick_load_image): Check that crop parameters fit into
12818 the integer types that MagickCropImage accepts. Don't assume
12819 Vimagemagick_render_type has a nonnegative value. Don't assume
12820 size_t fits in 'long'.
12821 (gs_load): Use printmax_t to print the widest integers possible.

12834 handle_single_display_spec, not just 1 or zero.
12835 (handle_single_display_spec): If the display spec is of the form
12836 `(space ...)', and specifies display in the text area, return 2
12838 (try_cursor_movement): Check for the need to scroll more
12839 accurately, and prefer exact match for point under bidi.
12840 Don't advance `row' beyond the last row of the window.

12858 buffers, return left-to-right.
12859 (set_cursor_from_row): Consider candidate row a win if its glyph
12860 represents a newline and point is on that newline. Fixes cursor
12861 positioning on the newline at EOL of R2L text within L2R
12862 paragraph, and vice versa.
12863 (try_cursor_movement): Check continued rows, in addition to
12864 continuation rows. Fixes unwarranted scroll when point enters a
12865 continued line of R2L text within an L2R paragraph, or vice versa.
12866 (cursor_row_p): Consider the case of point being equal to
12867 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
12868 from the end of a short line to the beginning of a continued line
12869 of R2L text within L2R paragraph.

12896 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
12897 instead of CHAR_TO_BYTE. Fixes a crash when a completion
12898 candidate is selected by the mouse, and that candidate has a
12899 composed character under the mouse.
12901 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
12902 coordinates reported by pos-visible-in-window-p for a composed
12903 character in column zero.

12911 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
12912 consider it a hit if to_charpos is anywhere in the range of the
12913 composed buffer positions.
12915 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
12917 * image.c (gif_load): Don't assume that each subimage has the same
12918 dimensions as the base image. Handle disposal method that is
12919 "undefined" by the gif spec (Bug#9335).
12921 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
12923 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

12933 a composition, take its buffer position from IT->cmp_it.charpos.
12934 Fixes cursor positioning at the beginning of a line that begins
12935 with a composed character.
12937 2011-08-18 Eli Zaretskii <eliz@gnu.org>
12939 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
12940 character bidirectional type, use STRONG_L instead. Fixes crashes
12941 in a buffer produced by `describe-categories'.
12943 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
12944 members before the level stack, so they would be saved and
12945 restored when copying iterator state. Fixes incorrect reordering
12946 around TABs covered by display properties.
12948 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>

13016 after the pid of the process is set to -1 (Bug#8162).
13018 2011-08-14 Eli Zaretskii <eliz@gnu.org>
13020 * xdisp.c (move_it_in_display_line_to): Don't invoke
13021 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
13022 ppos_it. Fixes vertical cursor motion when line beginning is
13023 covered by an image. (Bug#9296)
13025 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
13027 * nsterm.h (ns_run_ascript): Declare.
13028 (NSAPP_DATA2_RUNASSCRIPT): Define.
13030 * nsfns.m (as_script, as_result, as_status): New static variables.
13031 (ns_run_ascript): New function.
13032 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
13033 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
13034 the event loop. Get status from as_status (Bug#7276).
13036 * nsterm.m (sendEvent): If event is NSApplicationDefined and
13037 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
13038 the event loop (Bug#7276).
13040 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
13042 * gnutls.c (QCgnutls_bootprop_priority)
13043 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
13044 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
13045 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
13046 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
13047 (QCgnutls_bootprop_verify_hostname_error)
13048 (QCgnutls_bootprop_callbacks_verify): Rename from
13049 Qgnutls_bootprop_..., all uses changed.
13051 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
13054 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
13056 * xfaces.c (Qframe_set_background_mode): Now static.
13057 * dispextern.h (Qframe_set_background_mode): Remove decl.
13059 * process.c (Fnetwork_interface_info): Declare local only if needed.
13061 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
13063 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
13064 (Fnetwork_interface_list): Allocate in increments of bytes instead
13065 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
13066 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
13068 (struct ifflag_def): notrailers is smart on OSX.
13069 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
13070 Get hardware address with getifaddrs if available.
13072 2011-08-12 Eli Zaretskii <eliz@gnu.org>
13074 * xdisp.c (iterate_out_of_display_property): xassert that
13075 IT->position is set to within IT->object's boundaries. Break from
13076 the loop as soon as EOB is reached; avoids infloops in redisplay
13077 when IT->position is set up wrongly due to some bug.
13078 Set IT->current to match the bidi iterator unconditionally.
13079 (push_display_prop): Allow GET_FROM_STRING as IT->method on
13080 entry. Force push_it to save on the stack the current
13081 buffer/string position, to be restored by pop_it. Fix flags in
13082 the iterator structure wrt the object coming from a display
13083 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
13084 properties. (Bug#9284)
13086 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
13088 * fontset.c (fontset_get_font_group): Add proper type checks.
13091 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
13093 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
13094 and LC_VERSION_MIN_MACOSX.
13095 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
13096 (dump_it) [LC_FUNCTION_STARTS]: Use it.
13098 2011-08-08 Eli Zaretskii <eliz@gnu.org>
13100 * xdisp.c (forward_to_next_line_start): Allow to use the
13101 no-display-properties-and-no-overlays under bidi display.
13102 Set disp_pos in the bidi iterator to avoid searches for display
13103 properties and overlays.
13105 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
13107 * editfns.c (Fset_time_zone_rule): Document relationship with the
13110 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
13111 the font entity extracted from the cache (Bug#8109).
13113 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
13115 * composite.c (autocmp_chars): Don't reset point. That is done by
13116 restore_point_unwind (Bug#5984).
13118 2011-08-07 Juri Linkov <juri@jurta.org>
13120 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
13121 to show the arg `TIME' instead of `TIMEVAL'.
13123 2011-08-06 Eli Zaretskii <eliz@gnu.org>
13125 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
13126 display property strides EOL and includes a newline, as in
13127 longlines-mode. (Bug#9254)
13128 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
13129 word-wrap under bidirectional display. (Bug#9224)
13131 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
13132 is non-zero, even if the data buffer is NULL. Fixes a crash in
13133 vertical-motion with longlines-mode. (Bug#9254)
13135 2011-08-05 Eli Zaretskii <eliz@gnu.org>
13137 * bidi.c <bidi_cache_total_alloc>: Now static.
13138 (bidi_initialize): Initialize bidi_cache_total_alloc.
13140 * xdisp.c (display_line): Release buffer allocated for shelved bidi
13143 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
13144 amount allocated this far in `bidi_cache_total_alloc'.
13145 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
13146 non-zero, only free the data buffer without restoring the cache
13147 contents. All callers changed.
13149 * dispextern.h (bidi_unshelve_cache): Update prototype.
13151 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
13152 (move_it_in_display_line, move_it_to)
13153 (move_it_vertically_backward, move_it_by_lines): Replace the call
13154 to xfree to an equivalent call to bidi_unshelve_cache.
13155 (move_it_in_display_line_to): Fix logic of returning
13156 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
13158 2011-08-05 Eli Zaretskii <eliz@gnu.org>
13160 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
13161 came from a string character with a `cursor' property. (Bug#9229)
13163 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
13165 * Makefile.in (LIB_PTHREAD): New variable.
13166 (LIBES): Add LIB_PTHREAD (Bug#9216).
13168 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
13169 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
13171 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
13173 * regex.c (re_iswctype): Remove some redundant boolean conversions.
13175 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
13177 * xterm.c (x_find_topmost_parent): New function.
13178 (x_set_frame_alpha): Find topmost parent window with
13179 x_find_topmost_parent and set the property there also (bug#9181).
13180 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
13182 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
13184 * callproc.c (Fcall_process): Avoid vfork clobbering
13185 the local vars buffer, coding_systems, current_dir.
13187 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
13189 * keymap.c (Fmake_composed_keymap): Move to subr.el.
13191 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
13193 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
13194 so that it is not optimized away.
13196 * xdisp.c (compute_display_string_pos): Remove unused local.
13198 2011-08-02 Eli Zaretskii <eliz@gnu.org>
13200 Fix slow cursor motion and scrolling in large buffers with
13201 selective display, like Org Mode buffers. (Bug#9218)
13203 * dispextern.h (struct bidi_it): New member disp_prop_p.
13205 * xdisp.c: Remove one-slot cache of display string positions.
13206 (compute_display_string_pos): Accept an additional argument
13207 DISP_PROP_P; callers changed. Scan at most 5K characters forward
13208 for a display string or property. If found, set DISP_PROP_P
13211 * bidi.c (bidi_fetch_char): Accept an additional argument
13212 DISP_PROP_P, and pass it to compute_display_string_pos.
13213 Only handle text covered by a display string if DISP_PROP_P is returned
13214 non-zero. All callers of bidi_fetch_char changed.
13216 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
13218 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
13220 2010-12-03 Don March <don@ohspite.net>
13222 * keymap.c (Fdefine_key): Fix non-prefix key error message when
13223 last character M-[char] is translated to ESC [char] (bug#7541).
13225 2011-08-02 Kenichi Handa <handa@m17n.org>
13227 * lisp.h (uniprop_table): Extern it.
13229 * chartab.c (uniprop_table): Make it non-static.
13231 2011-08-01 Eli Zaretskii <eliz@gnu.org>
13233 * xdisp.c (forward_to_next_line_start): Accept additional argument
13234 BIDI_IT_PREV, and store into it the state of the bidi iterator had
13236 (reseat_at_next_visible_line_start): Use the bidi iterator state
13237 returned by forward_to_next_line_start to restore the state of
13238 it->bidi_it after backing up to previous newline. (Bug#9212)
13240 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
13242 * regex.c (re_comp): Protoize.
13243 (re_exec): Fix return type.
13244 (regexec): Fix type of `ret'. (Bug#9203)
13246 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
13248 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
13249 This is needed if max-image-size is a floating-point number.
13251 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
13253 * print.c (print_object): Print empty symbol as ##.
13255 * lread.c (read1): Read ## as empty symbol.
13257 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
13259 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
13260 setting frame foreground color (Bug#9175).
13261 (x_set_background_color): Likewise.
13263 * nsmenu.m (-setText): Size tooltip dimensions precisely to
13264 contents (Bug#9176).
13265 (EmacsTooltip -init): Remove bezels and add shadows to
13268 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
13269 or scroll bar (Bug#8470).
13271 * nsfont.m (nsfont_open): Remove assignment to voffset and
13272 unnecessary vars hshink, expand, hd, full_height, min_height.
13273 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
13275 * nsterm.h (nsfont_info): Remove voffset field.
13277 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
13279 Implement strike-through and overline on NextStep (Bug#8863).
13281 * nsfont.m (nsfont_open): Use underline position provided by font,
13282 instead of hard-coded value of 2.
13283 (nsfont_draw): Call ns_draw_text_decoration instead.
13285 * nsterm.h: Add declaration for ns_draw_text_decoration.
13287 * nsterm.m (ns_draw_text_decoration): New function for drawing
13288 underline, overline, and strike-through.
13289 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
13290 ns_draw_text_decoration. Change treatment of cursor drawing to
13291 accommodate underlining, etc.
13293 2011-07-28 Eli Zaretskii <eliz@gnu.org>
13295 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
13298 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
13300 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
13301 Without this fix, if a signal arrives just after memory fills up,
13302 'malloc' might be invoked reentrantly.
13304 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
13305 In other words, assume that every image size is allowed, on non-X
13306 hosts. This assumption is probably wrong, but it lets Emacs compile.
13308 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
13310 * regex.c (re_iswctype): Convert return values to boolean.
13312 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
13314 * xdisp.c (compute_display_string_pos): Don't use cached display
13315 string position if the buffer had its restriction changed.
13318 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
13320 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
13322 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
13324 Integer signedness and overflow and related fixes. (Bug#9079)
13326 * bidi.c: Integer size and overflow fixes.
13327 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
13328 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
13329 (bidi_cache_find_level_change, bidi_cache_ensure_space)
13330 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
13331 (bidi_find_other_level_edge):
13332 Use ptrdiff_t instead of EMACS_INT where either will do.
13333 This works better on 32-bit hosts configured --with-wide-int.
13334 (bidi_cache_ensure_space): Check for size-calculation overflow.
13335 Use % rather than repeated addition, for better worst-case speed.
13336 Don't set bidi_cache_size until after xrealloc returns, because it
13338 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
13339 (bidi_cache_ensure_space): Also check that the bidi cache size
13340 does not exceed that of the largest Lisp string or buffer. See Eli
13341 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
13343 * alloc.c (__malloc_size_t): Remove.
13344 All uses replaced by size_t. See Andreas Schwab's note
13345 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
13347 * image.c: Improve checking for integer overflow.
13348 (check_image_size): Assume that f is nonnull, since
13349 it is always nonnull in practice. This is one less thing to
13350 worry about when checking for integer overflow later.
13351 (x_check_image_size): New function, which checks for integer
13352 overflow issues inside X.
13353 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
13354 This removes the need for a memory_full check.
13355 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
13356 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
13357 (xbm_read_bitmap_data): Change locals back to 'int', since
13358 their values must fit in 'int'.
13359 (xpm_load_image, png_load, tiff_load):
13360 Invoke x_create_x_image_and_pixmap earlier,
13361 to avoid much needless work if the image is too large.
13362 (tiff_load): Treat overly large images as if
13363 x_create_x_image_and_pixmap failed, not as malloc failures.
13364 (gs_load): Use x_check_image_size.
13366 * gtkutil.c: Omit integer casts.
13367 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
13368 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
13370 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
13372 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
13373 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
13374 would wrongly return t on a 64-bit host.
13376 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
13377 The plain *_OVERFLOW macros run afoul of GCC bug 49705
13378 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
13379 and therefore cause GCC to emit a bogus diagnostic in some cases.
13381 * image.c: Integer signedness and overflow and related fixes.
13382 This is not an exhaustive set of fixes, but it's time to
13383 record what I've got.
13384 (lookup_pixel_color, check_image_size): Remove redundant decls.
13385 (check_image_size): Don't assume that arbitrary EMACS_INT values
13386 fit in 'int', or that arbitrary 'double' values fit in 'int'.
13387 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
13388 (tiff_load, imagemagick_load_image):
13389 Check for overflow in size calculations.
13390 (x_create_x_image_and_pixmap): Remove unnecessary test for
13391 xmalloc returning NULL; that can't happen.
13392 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
13393 (xpm_color_bucket): Use better integer hashing function.
13394 (xpm_cache_color): Don't possibly over-allocate memory.
13395 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
13396 (gif_memory_source):
13397 Use ptrdiff_t, not int or size_t, to record sizes.
13398 (png_load): Don't assume values greater than 2**31 fit in 'int'.
13399 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
13400 either works, as we prefer signed integers.
13401 (tiff_read_from_memory, tiff_write_from_memory):
13402 Return tsize_t, not size_t, since that's what the TIFF API wants.
13403 (tiff_read_from_memory): Don't fail simply because the read would
13404 go past EOF; instead, return a short read.
13405 (tiff_load): Omit no-longer-needed casts.
13406 (Fimagemagick_types): Don't assume size fits into 'int'.
13408 Improve hashing quality when configured --with-wide-int.
13409 * fns.c (hash_string): New function, taken from sxhash_string.
13410 Do not discard information about ASCII character case; this
13411 discarding is no longer needed.
13412 (sxhash-string): Use it. Change sig to match it. Caller changed.
13413 * lisp.h: Declare it.
13414 * lread.c (hash_string): Remove, since we now use fns.c's version.
13415 The fns.c version returns a wider integer if --with-wide-int is
13416 specified, so this should help the quality of the hashing a bit.
13418 * emacs.c: Integer overflow minor fix.
13419 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
13420 Define only if GNU_LINUX.
13421 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
13423 * dispnew.c: Integer signedness and overflow fixes.
13424 Remove unnecessary forward decls, that were a maintenance hassle.
13425 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
13427 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
13428 (scrolling_window): Use ptrdiff_t, not int, for byte count.
13429 (prepare_desired_row, line_draw_cost):
13430 Use int, not unsigned, where either works.
13431 (save_current_matrix, restore_current_matrix):
13432 Use ptrdiff_t, not size_t, where either works.
13433 (init_display): Check for overflow more accurately, and without
13434 relying on undefined behavior.
13436 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
13437 Remove, replacing with the new symbols in lisp.h. All uses changed.
13438 * fileio.c (make_temp_name):
13439 * filelock.c (lock_file_1, lock_file):
13440 * xdisp.c (message_dolog):
13441 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
13442 Use pMd etc. instead.
13443 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
13444 replacing the pWIDE etc. symbols removed from editfns.c.
13446 * keyboard.h (num_input_events): Now uintmax_t.
13447 This is (very slightly) less likely to mess up due to wraparound.
13450 * buffer.c: Integer signedness fixes.
13451 (alloc_buffer_text, enlarge_buffer_text):
13452 Use ptrdiff_t rather than size_t when either will do, as we prefer
13455 * alloc.c: Integer signedness and overflow fixes.
13456 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
13457 (__malloc_size_t): Default to size_t, not to int.
13458 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
13459 (Fgarbage_collect, mark_object_loop_halt, mark_object):
13460 Prefer ptrdiff_t to size_t when either would do, as we prefer
13462 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
13463 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
13464 Now const. Initialize with values that are in range even if char
13466 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
13467 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
13468 These functions do the right thing with sizes > 2**32.
13469 (check_depth): Now ptrdiff_t, not int.
13470 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
13471 Adjust to new way of storing sizes. Check for size overflow bugs
13473 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
13474 slightly wrong anyway, as it missed one instance of
13475 XMALLOC_OVERRUN_CHECK_OVERHEAD.
13476 (refill_memory_reserve): Omit needless cast to size_t.
13477 (mark_object_loop_halt): Mark as externally visible.
13479 * xselect.c: Integer signedness and overflow fixes.
13480 (Fx_register_dnd_atom, x_handle_dnd_message):
13481 Use ptrdiff_t, not size_t, since we prefer signed.
13482 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
13483 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
13484 x_dnd_atoms_size and x_dnd_atoms_length.
13486 * doprnt.c: Prefer signed to unsigned when either works.
13488 * doprnt.c (doprnt):
13490 * xdisp.c (vmessage):
13491 Use ptrdiff_t, not size_t, when using or implementing doprnt,
13492 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
13493 prefer signed arithmetic to avoid comparison confusion.
13494 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
13495 but is a bit tricky.
13497 Assume freestanding C89 headers, string.h, stdlib.h.
13498 * data.c, doprnt.c, floatfns.c, print.c:
13499 Include float.h unconditionally.
13500 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
13501 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
13502 * regex.c: Likewise for stddef.h, string.h.
13503 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
13504 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
13505 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
13506 (STDC_HEADERS): Remove obsolete defines.
13507 * sysdep.c: Include limits.h unconditionally.
13509 Assume support for memcmp, memcpy, memmove, memset.
13510 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
13511 * regex.c (memcmp, memcpy):
13512 Remove; we assume C89 now.
13514 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
13515 (__malloc_safe_bcopy): Remove; no longer needed.
13517 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
13518 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
13519 well either way, and we prefer signed to unsigned.
13521 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
13523 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
13524 closes the connection while we're reading (bug#9182).
13526 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
13528 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
13529 are specified (Bug#9168).
13531 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
13533 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
13534 Found by GCC static checking and --with-wide-int on a 32-bit host.
13536 2011-07-25 Eli Zaretskii <eliz@gnu.org>
13538 * xdisp.c (compute_display_string_pos): Fix logic of caching
13539 previous display string position. Initialize cached_prev_pos to
13540 -1. Fixes slow-down at the beginning of a buffer.
13542 2011-07-24 Eli Zaretskii <eliz@gnu.org>
13544 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
13545 for attrs[LFACE_FONTSET_INDEX].
13547 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
13549 * xml.c (parse_region): Remove unused local
13550 that was recently introduced.
13552 2011-07-23 Eli Zaretskii <eliz@gnu.org>
13554 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
13555 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
13557 * xdisp.c (move_it_in_display_line_to): Record the best matching
13558 position for TO_CHARPOS while scanning the line, and restore it on
13559 exit if none of the characters scanned was an exact match.
13560 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
13561 when exact match is impossible due to invisible text, and the
13562 lines are truncated.
13564 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
13566 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
13569 2011-07-22 Eli Zaretskii <eliz@gnu.org>
13571 Fix a significant slow-down of cursor motion with C-n, C-p,
13572 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
13573 auto-repeat under bidi redisplay in fontified buffers.
13574 * xdisp.c (compute_stop_pos_backwards): New function.
13575 (next_element_from_buffer): Call compute_stop_pos_backwards to
13576 find a suitable prev_stop when we find ourselves before
13578 (reseat): Don't look for prev_stop, as that could mean a very long
13580 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
13581 <cached_disp_overlay_modiff>: Cache for last found display string
13583 (compute_display_string_pos): Return the cached position if asked
13584 about the same buffer in the same area of character positions, and
13585 the buffer wasn't changed since the time the display string
13586 position was cached.
13588 2011-07-22 Eli Zaretskii <eliz@gnu.org>
13590 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
13591 is an integer, which is important for empty lines. (Bug#9149)
13593 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
13595 * frame.c (Fmodify_frame_parameters): In tty case, update the
13596 default face if necessary (Bug#4238).
13598 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
13600 * editfns.c (Fstring_to_char): No need to explain what a character
13601 is in the docstring (Bug#6576).
13603 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
13605 * xml.c (parse_region): Make sure we always return a tree.
13607 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
13609 * xml.c (parse_region): If a document contains only comments,
13612 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
13614 * xml.c (make_dom): Return comments, too.
13616 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
13619 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
13620 and the surrounding thread.
13621 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
13622 rather than fgets, and retry after EINTR. Otherwise, 'emacs
13623 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
13625 * s/openbsd.h (BROKEN_SIGIO): Define.
13626 * unexelf.c (unexec) [__OpenBSD__]:
13627 Don't update the .mdebug section of the Alpha COFF symbol table.
13629 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
13631 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
13634 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
13636 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
13637 This fixes some race conditions on the permissions of any newly
13640 * alloc.c (valid_pointer_p): Use pipe, not open.
13641 This fixes some permissions issues when debugging.
13643 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
13644 If fchown fails to set both uid and gid, try to set just gid,
13645 as that is sometimes allowed. Adjust the file's mode to eliminate
13646 setuid or setgid bits that are inappropriate if fchown fails.
13648 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
13650 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
13651 to compare Lisp_Objects.
13652 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
13653 global_gnutls_log_level, don't mistake it for a Lisp_Object.
13654 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
13656 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
13658 * lread.c (read_integer): Unread even EOF character.
13659 (read1): Likewise. Properly record start position of symbol.
13661 * lread.c (read1): Read `#:' as empty uninterned symbol if no
13662 symbol character follows.
13664 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
13666 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
13667 This works around a problem with the previous change to Fcopy_file.
13668 Recent glibc declares fchown with __attribute__((warn_unused_result)),
13669 and without this change, GCC might complain about discarding
13670 fchown's return value.
13672 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
13674 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
13676 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
13678 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
13680 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
13682 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
13683 it's used from the C level.
13685 * process.c: Use the same condition for POLL_FOR_INPUT in both
13686 keyboard.c and process.c (bug#1858).
13688 2011-07-09 Lawrence Mitchell <wence@gmx.li>
13690 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
13691 (Fgnutls_boot): Use it.
13693 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
13695 * doc.c (Fsubstitute_command_keys): Revert last change.
13697 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
13699 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
13700 quotes the next character, and doesn't affect other longer
13701 sequences (bug#8935).
13703 * lread.c (syms_of_lread): Clarify that is isn't only
13704 `eval-buffer' and `eval-defun' that's affected by
13705 `lexical-binding' (bug#8460).
13707 2011-07-15 Eli Zaretskii <eliz@gnu.org>
13709 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
13710 bidi redisplay when a line includes both an image and is truncated.
13712 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
13714 Fix minor problems found by static checking.
13715 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
13716 (elsz): Now a signed constant, not a size_t var. We prefer signed
13717 types to unsigned, to avoid integer comparison confusion. Without
13718 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
13719 "cannot optimize loop, the loop counter may overflow", a symptom
13721 * indent.c (Fvertical_motion): Mark locals as initialized.
13722 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
13724 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
13726 * search.c (Fre_search_backward): Mention `case-fold-search' in
13727 all the re_search_* functions (bug#8138).
13729 * keyboard.c (Fopen_dribble_file): Document when the file is

13740 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
13741 (reseat_to_string): Initialize bidi_it->string.s and
13742 bidi_it->string.schars.
13743 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
13744 NULL (avoids a crash in bidi_paragraph_init).
13745 Initialize itb.string.lstring.
13746 (init_iterator): Call bidi_init_it only of a valid
13747 buffer position was specified. Initialize paragraph_embedding to
13749 (reseat_to_string): Initialize the bidi iterator.
13750 (display_string): If we need to ignore text properties of
13751 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
13752 original value of -1 will not work with bidi.)
13753 (compute_display_string_pos): First arg is now struct
13754 `text_pos *'; all callers changed. Support display properties on
13756 (compute_display_string_end): Support display properties on Lisp
13758 (init_iterator, reseat_1, reseat_to_string): Initialize the
13759 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
13760 when iterating on a string not from display properties).
13761 (compute_display_string_pos, compute_display_string_end):
13762 Fix calculation of the object to scan. Fixes an error when using
13764 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
13765 base_level_stop; instead, set base_level_stop to BEGV.
13766 Fixes crashes in vertical-motion.
13767 (next_element_from_buffer): Improve commentary for when
13768 the iterator is before prev_stop.
13769 (init_iterator): Initialize bidi_p from the default value of
13770 bidi-display-reordering, not from buffer-local value. Use the
13771 buffer-local value only if initializing for buffer iteration.
13772 (handle_invisible_prop): Support invisible properties on strings
13773 that are being bidi-reordered.
13774 (set_iterator_to_next): Support bidi reordering of C strings and
13776 (next_element_from_string): Support bidi reordering of Lisp
13778 (handle_stop_backwards): Support Lisp strings as well.
13779 (display_string): Support display of R2L glyph rows.
13780 Use IT_STRING_CHARPOS when displaying from a Lisp string.
13781 (init_iterator): Don't initialize it->bidi_p for strings
13783 (reseat_to_string): Initialize it->bidi_p for strings here.
13784 (next_element_from_string, next_element_from_c_string)
13785 (next_element_from_buffer): Add xassert's for correspondence
13786 between IT's object being iterated and it->bidi_it.string
13788 (face_before_or_after_it_pos): Support bidi iteration.
13789 (next_element_from_c_string): Handle the case of the first string
13790 character that is not the first one in the visual order.
13791 (get_visually_first_element): New function, refactored from common
13792 parts of next_element_from_buffer, next_element_from_string, and
13793 next_element_from_c_string.
13794 (tool_bar_lines_needed, redisplay_tool_bar)
13795 (display_menu_bar): Force left-to-right direction. Add a FIXME
13796 comment for making that be controlled by a user option.
13797 (push_it, pop_it): Save and restore the state of the
13798 bidi iterator. Save and restore the bidi_p flag.
13799 (pop_it): Iterate out of display property for string iteration as
13801 (iterate_out_of_display_property): Support iteration over strings.
13802 (handle_single_display_spec): Set up it->bidi_it for iteration
13803 over a display string, and call bidi_init_it.
13804 (handle_single_display_spec, next_overlay_string)
13805 (get_overlay_strings_1, push_display_prop): Set up the bidi
13806 iterator for displaying display or overlay strings.
13807 (forward_to_next_line_start): Don't use the shortcut if
13809 (back_to_previous_visible_line_start): If handle_display_prop
13810 pushed the iterator stack, restore the internal state of the bidi
13811 iterator by calling bidi_pop_it same number of times.
13812 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
13813 and we are bidi-iterating, don't decrement the iterator position;
13814 instead, set the first_elt flag in the bidi iterator, to produce
13816 (reseat_1): Remove redundant setting of string_from_display_prop_p.
13817 (push_display_prop): xassert that we are iterating a buffer.
13818 (push_it, pop_it): Save and restore paragraph_embedding member.
13819 (handle_single_display_spec, next_overlay_string)
13820 (get_overlay_strings_1, reseat_1, reseat_to_string)
13821 (push_display_prop): Set up the `unibyte' member of bidi_it.string
13822 correctly. Don't assume unibyte strings are not bidi-reordered.
13823 (compute_display_string_pos)
13824 (compute_display_string_end): Fix handling the case of C string.
13825 (push_it, pop_it): Save and restore from_disp_prop_p.
13826 (handle_single_display_spec, push_display_prop): Set the
13827 from_disp_prop_p flag.
13828 (get_overlay_strings_1): Reset the from_disp_prop_p flag.

13830 popping after iteration over a string that came from a display
13831 property. Fix a typo in popping stretch info. Add an assertion
13832 for verifying that the iterator position is in sync with the bidi
13834 (handle_single_display_spec, get_overlay_strings_1)
13835 (push_display_prop): Fix initialization of paragraph direction for
13836 string when that of the parent object is not yet determined.
13837 (reseat_1): Call bidi_init_it to resync the bidi
13838 iterator with IT's position. (Bug#7616)
13839 (find_row_edges): If ROW->start.pos gives position
13840 smaller than min_pos, use it as ROW->minpos. (Bug#7616)
13841 (handle_stop, back_to_previous_visible_line_start, reseat_1):
13842 Reset the from_disp_prop_p flag.
13843 (SAVE_IT, RESTORE_IT): New macros.
13844 (pos_visible_p, face_before_or_after_it_pos)
13845 (back_to_previous_visible_line_start)
13846 (move_it_in_display_line_to, move_it_in_display_line)
13847 (move_it_to, move_it_vertically_backward, move_it_by_lines)
13848 (try_scrolling, redisplay_window, display_line): Use them when
13849 saving a temporary copy of the iterator and restoring it back.
13850 (back_to_previous_visible_line_start, reseat_1)
13851 (init_iterator): Empty the bidi cache "stack".
13852 (move_it_in_display_line_to): If iterator ended up at
13853 EOL, but we never saw any buffer positions smaller than
13854 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
13855 motion in bidi-reordered lines.
13856 (move_it_in_display_line_to): Record prev_method and prev_pos
13857 immediately before the call to set_iterator_to_next. Fixes cursor
13858 motion in bidi-reordered lines with stretch glyphs and strings
13859 displayed in margins. (Bug#8133) (Bug#8867)
13860 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
13862 (pos_visible_p): Support positions in bidi-reordered lines.
13863 Save and restore bidi cache.
13865 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.
13866 (bidi_paragraph_info): Delete unused struct.
13867 (bidi_cache_idx, bidi_cache_last_idx): Declare EMACS_INT.
13868 (bidi_cache_start): New variable.
13869 (bidi_cache_reset): Reset bidi_cache_idx to bidi_cache_start, not
13871 (bidi_cache_fetch_state, bidi_cache_search)
13872 (bidi_cache_find_level_change, bidi_cache_iterator_state)
13873 (bidi_cache_find, bidi_peek_at_next_level)

13877 (bidi_fetch_char): Accept new argument STRING; all callers
13878 changed. Support iteration over a string. Support strings with
13879 display properties. Support unibyte strings. Fix the type of
13880 `len' according to what STRING_CHAR_AND_LENGTH expects.
13881 (bidi_paragraph_init, bidi_resolve_explicit_1)
13882 (bidi_resolve_explicit, bidi_resolve_weak)
13883 (bidi_level_of_next_char, bidi_move_to_visually_next):
13884 Support iteration over a string.
13885 (bidi_set_sor_type, bidi_resolve_explicit_1)
13886 (bidi_resolve_explicit, bidi_type_of_next_char): ignore_bn_limit
13887 can now be zero (for strings); special values 0 and -1 were
13888 changed to -1 and -2, respectively.
13889 (bidi_char_at_pos): New function.
13890 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak):

13976 2011-07-13 Paul Eggert <eggert@cs.ucla.edu>
13978 * buffer.c (Fget_buffer_create): Initialize inhibit_shrinking.
13979 The old code sometimes used this field without initializing it.
13981 * alloc.c (gc_sweep): Don't read past end of array.
13982 In theory, the old code could also have corrupted Emacs internals,
13983 though it'd be very unlikely.

13987 * character.c (Fcharacterp): Don't advertise optional ignored

14087 sigprocmask is portable only for single-threaded applications, and
14088 Emacs can be multi-threaded when it uses GTK.

14246 (clone_per_buffer_values): Don't assume that
14247 sizeof (struct buffer) is a multiple of sizeof (Lisp_Object).
14248 This isn't true in general, and it's particularly not true
14249 if Emacs is configured with --with-wide-int.
14250 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
14251 New macros, used in the buffer.c change.

14287 Random fixes. E.g., (random) never returned negative values.
14288 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
14289 subseconds part to the entropy, as that's a bit more random.
14290 Prefer signed to unsigned, since the signedness doesn't matter and
14291 in general we prefer signed. When given a limit, use a
14292 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
14293 latter isn't right if USE_2_TAGS_FOR_INTS.
14294 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
14295 not 0..VALMASK. Don't discard "excess" bits that random () returns.

14305 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
14307 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
14308 This is more efficient than Ffile_directory_p and avoids a minor race.
14310 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
14312 * buffer.c (Foverlay_put): Say what the return value is
14315 * fileio.c (barf_or_query_if_file_exists): Check first if the file
14316 is a directory before asking whether to use the file name
14318 (barf_or_query_if_file_exists): Make the "File is a directory"
14319 error be more correct.
14321 * fns.c (Frequire): Remove the mention of the .gz files, since
14322 that's installation-specific, but keep the mention of
14323 `get-load-suffixes'.
14325 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
14327 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

14333 (syms_of_gnutls): Remove duplicate DEFSYM for

14440 * eval.c (struct backtrace): Simplify and port the data structure.
14441 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
14442 signed bit field, as this assumption is not portable and it makes
14443 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
14444 "char debug_on_exit : 1" as this is not portable either; instead,
14445 use the portable "unsigned int debug_on_exit : 1". Remove unused
14446 member evalargs. Remove obsolete comments about cc bombing out.

14682 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
14683 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
14684 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
14685 since we're not interested in debugging glyphs with old libraries.
14686 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
14687 GCC 4.6.0's static checking.

14729 (x_session_initialize): Do not assume string length fits in int.
14731 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.

14775 Invoke gzip -cd rather than gunzip, as it's more portable.
14776 (lock_info_type, lock_file_1, lock_file):
14777 Don't assume pid_t and time_t fit in unsigned long.
14778 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
14779 (current_lock_owner): Prefer signed type for sizes.
14780 Use memcpy, not strncpy, where memcpy is what is really wanted.
14781 Don't assume (via atoi) that time_t and pid_t fit in int.
14782 Check for time_t and/or pid_t out of range, e.g., via a network share.
14783 Don't alloca where an auto var works fine.
14785 * fileio.c: Fix some integer overflow issues.
14786 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
14787 Don't assume string length fits in int.
14788 (directory_file_name): Don't assume string length fits in long.
14789 (make_temp_name): Don't assume pid fits in int, or that its print
14790 length is less than 20.
14792 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
14794 * coding.c (make_subsidiaries): Don't assume string length fits in int.
14796 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
14798 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
14799 We prefer signed integers, even for size calculations.
14801 * emacs.c: Don't assume string length fits in 'int'.
14802 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
14803 (main): Don't invoke strlen when not needed.
14805 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
14806 (XD_DEBUG_MESSAGE): Don't waste a byte.
14808 * callproc.c (getenv_internal_1, getenv_internal)
14809 (Fgetenv_internal):
14810 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
14812 * lread.c (invalid_syntax): Omit length argument.
14813 All uses changed. This doesn't fix a bug, but it simplifies the
14814 code away from its former Hollerith-constant appearance, and it's
14815 one less 'int' to worry about when looking at integer-overflow issues.
14816 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
14818 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
14819 This didn't break anything, but it didn't help either.
14820 It's confusing to put a bogus integer in a place where the actual
14821 value does not matter.
14822 (LIST_END_P): Remove unused macro and its bogus comment.
14823 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
14825 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
14826 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
14828 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
14829 We prefer signed types, and the value cannot exceed the EMACS_INT
14830 range anyway (because otherwise the length would not be representable).
14831 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
14832 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
14833 This avoids a GCC warning when WIDE_EMACS_INT.
14835 * indent.c (sane_tab_width): New function.
14836 (current_column, scan_for_column, Findent_to, position_indentation)
14837 (compute_motion): Use it. This is just for clarity.
14838 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
14840 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
14842 * lisp.h (lint_assume): New macro.
14843 * composite.c (composition_gstring_put_cache):
14844 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
14846 * editfns.c, insdel.c:
14847 Omit unnecessary forward decls, to simplify future changes.
14849 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
14851 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
14853 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
14854 Use much-faster test for byte-length change.
14855 Don't assume string byte-length fits in 'int'.
14856 Check that character arg fits in 'int'.
14857 (mapcar1): Declare byte as byte, for clarity.
14859 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
14861 * fns.c (concat): Catch string overflow earlier.
14862 Do not rely on integer wraparound.
14864 * dispextern.h (struct it.overlay_strings_charpos)
14865 (struct it.selective): Now EMACS_INT, not int.
14866 * xdisp.c (forward_to_next_line_start)
14867 (back_to_previous_visible_line_start)
14868 (reseat_at_next_visible_line_start, next_element_from_buffer):
14869 Don't arbitrarily truncate the value of 'selective' to int.
14871 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
14873 * composite.c: Don't truncate sizes to 'int'.
14874 (composition_gstring_p, composition_reseat_it)
14875 (composition_adjust_point): Use EMACS_INT, not int.
14876 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
14877 not EMACS_UINT, for indexes.
14879 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
14881 * buffer.c: Include <verify.h>.
14882 (struct sortvec.priority, struct sortstr.priority):
14883 Now EMACS_INT, not int.
14884 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
14885 (struct sortstr.size, record_overlay_string)
14886 (struct sortstrlist.size, struct sortlist.used):
14887 Don't truncate size to int.
14888 (record_overlay_string): Check for size-calculation overflow.
14889 (init_buffer_once): Check at compile-time, not run-time.
14891 2011-06-22 Jim Meyering <meyering@redhat.com>
14893 Don't leak an XBM-image-sized buffer
14894 * image.c (xbm_load): Free the image buffer after using it.
14896 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
14899 * composite.c (find_automatic_composition): Omit needless 'return 0;'
14900 that Sun C diagnosed.
14901 * fns.c (secure_hash): Fix pointer signedness issue.
14902 * intervals.c (static_offset_intervals): New function.
14903 (offset_intervals): Use it.
14905 2011-06-21 Leo Liu <sdl.web@gmail.com>
14908 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
14911 * fns.c (secure_hash): Rename from crypto_hash_function and change
14912 the first arg to accept symbols.
14913 (Fsecure_hash): New primitive.
14914 (syms_of_fns): New symbols.
14916 2011-06-20 Deniz Dogan <deniz@dogan.se>
14918 * process.c (Fset_process_buffer): Clarify return value in
14921 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
14923 * dispnew.c (add_window_display_history): Use BVAR.
14925 * xdisp.c (debug_method_add): Use BVAR.
14926 (check_window_end, dump_glyph_matrix, dump_glyph)
14927 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
14929 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
14932 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
14933 check till after the cache is created in init_frame_faces.
14935 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
14937 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
14939 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
14941 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
14942 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
14943 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
14945 Improve buffer-overflow checking (Bug#8873).
14946 * fileio.c (Finsert_file_contents):
14947 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
14948 Remove the old (too-loose) buffer overflow checks.
14949 They weren't needed, since make_gap checks for buffer overflow.
14950 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
14951 The old code merely checked for Emacs fixnum overflow, and relied
14952 on undefined (wraparound) behavior. The new code avoids undefined
14953 behavior, and also checks for ptrdiff_t and/or size_t overflow.
14955 * editfns.c (Finsert_char): Don't dump core with very negative counts.
14956 Tune. Don't use wider integers than needed. Don't use alloca.
14957 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
14959 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
14961 * insdel.c, lisp.h (buffer_overflow): New function.
14962 (insert_from_buffer_1, replace_range, replace_range_2):
14963 * insdel.c (make_gap_larger):
14964 * editfns.c (Finsert_char):
14965 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
14967 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
14969 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
14971 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
14973 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
14974 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
14976 * fileio.c: Don't assume EMACS_INT fits in off_t.
14977 (emacs_lseek): New static function.
14978 (Finsert_file_contents, Fwrite_region): Use it.
14979 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
14981 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
14983 * fns.c: Don't overflow int when computing a list length.
14984 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
14985 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
14986 truncation on 64-bit hosts. Check for QUIT every
14987 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
14988 faster and is responsive enough.
14989 (Flength): Report an error instead of overflowing an integer.
14990 (Fsafe_length): Return a float if the value is not representable
14991 as a fixnum. This shouldn't happen except in contrived situations.
14992 (Fnthcdr, Fsort): Don't assume list length fits in int.
14993 (Fcopy_sequence): Don't assume vector length fits in int.
14995 * alloc.c: Check that resized vectors' lengths fit in fixnums.
14996 (header_size, word_size): New constants.
14997 (allocate_vectorlike): Don't check size overflow here.
14998 (allocate_vector): Check it here instead, since this is the only
14999 caller of allocate_vectorlike that could cause overflow.
15000 Check that the new vector's length is representable as a fixnum.
15002 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
15003 The previous code was bogus. For example, next_almost_prime (32)
15004 returned 39, which is undesirable as it is a multiple of 3; and
15005 next_almost_prime (24) returned 25, which is a multiple of 5 so
15006 why was the code bothering to check for multiples of 7?
15008 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
15010 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
15012 Variadic C functions now count arguments with ptrdiff_t.
15013 This partly undoes my 2011-03-30 change, which replaced int with size_t.
15014 Back then I didn't know that the Emacs coding style prefers signed int.
15015 Also, in the meantime I found a few more instances where arguments
15016 were being counted with int, which may truncate counts on 64-bit
15017 machines, or EMACS_INT, which may be unnecessarily wide.
15018 * lisp.h (struct Lisp_Subr.function.aMANY)
15019 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
15020 Arg counts are now ptrdiff_t, not size_t.
15021 All variadic functions and their callers changed accordingly.
15022 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
15023 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
15024 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
15025 * callint.c (Fcall_interactively): Check arg count for overflow,
15026 to avoid potential buffer overrun. Use signed char, not 'int',
15027 for 'varies' array, so that we needn't bother to check its size
15028 calculation for overflow.
15029 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
15030 * eval.c (apply_lambda):
15031 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
15032 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
15033 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
15035 * callint.c (Fcall_interactively): Don't use index var as event count.
15037 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
15038 * mem-limits.h (SIZE): Remove; no longer used.
15040 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
15042 Remove unnecessary casts.
15043 * xterm.c (x_term_init):
15044 * xfns.c (x_set_border_pixel):
15045 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
15046 These aren't needed now that we assume ANSI C.
15048 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
15049 It's more likely to cause problems (due to unsigned overflow)
15052 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
15054 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
15056 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
15058 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
15060 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
15062 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
15064 GLYPH_CODE_FACE returns EMACS_INT, not int.
15065 * dispextern.h (merge_faces):
15066 * xfaces.c (merge_faces):
15067 * xdisp.c (get_next_display_element, next_element_from_display_vector):
15068 Don't assume EMACS_INT fits in int.
15070 * character.h (CHAR_VALID_P): Remove unused parameter.
15071 * fontset.c, lisp.h, xdisp.c: All uses changed.
15073 * editfns.c (Ftranslate_region_internal): Omit redundant test.
15075 * fns.c (concat): Minor tuning based on overflow analysis.
15076 This doesn't fix any bugs. Use int to hold character, instead
15077 of constantly refetching from Emacs object. Use XFASTINT, not
15078 XINT, for value known to be a character. Don't bother comparing
15079 a single byte to 0400, as it's always less.
15081 * floatfns.c (Fexpt):
15082 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
15084 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
15087 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
15089 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
15090 Without this fix, on a 64-bit host (aset S 0 4294967386) would
15091 incorrectly succeed when S was a string, because 4294967386 was
15092 truncated before it was used.
15094 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
15095 Otherwise, an out-of-range integer could cause undefined behavior
15098 * composite.c: Use int, not EMACS_INT, for characters.
15099 (fill_gstring_body, composition_compute_stop_pos): Use int, not
15100 EMACS_INT, for values that are known to be in character range.
15101 This doesn't fix any bugs but is the usual style inside Emacs and
15102 may generate better code on 32-bit machines.
15104 Make sure a 64-bit char is never passed to ENCODE_CHAR.
15105 This is for reasons similar to the recent CHAR_STRING fix.
15106 * charset.c (Fencode_char): Check that character arg is actually
15107 a character. Pass an int to ENCODE_CHAR.
15108 * charset.h (ENCODE_CHAR): Verify that the character argument is no
15109 wider than 'int', as a compile-time check to prevent future regressions
15112 * character.c (char_string): Remove unnecessary casts.
15114 Make sure a 64-bit char is never passed to CHAR_STRING.
15115 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
15116 by silently ignoring the top 32 bits, allowing some values
15117 that were far too large to be valid characters.
15118 * character.h: Include <verify.h>.
15119 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
15120 arguments are no wider than unsigned, as a compile-time check
15121 to prevent future regressions in this area.
15123 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
15124 (Fsubst_char_in_region):
15126 * xdisp.c (decode_mode_spec_coding):
15127 Adjust to CHAR_STRING's new requirement.
15128 * editfns.c (Finsert_char, Fsubst_char_in_region):
15129 * fns.c (concat): Check that character args are actually
15130 characters. Without this test, these functions did the wrong
15131 thing with wildly out-of-range values on 64-bit hosts.
15133 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
15134 These casts should not be needed on 32-bit hosts, either.
15135 * keyboard.c (read_char):
15136 * lread.c (Fload): Remove casts to unsigned.
15138 * lisp.h (UNSIGNED_CMP): New macro.
15139 This fixes comparison bugs on 64-bit hosts.
15140 (ASCII_CHAR_P): Use it.
15141 * casefiddle.c (casify_object):
15142 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
15143 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
15144 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
15145 * dispextern.h (FACE_FROM_ID):
15146 * keyboard.c (read_char): Use UNSIGNED_CMP.
15148 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
15149 not to EMACS_INT, to avoid GCC warning.
15151 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
15153 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
15154 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
15155 isn't needed on 32-bit machines.
15157 * buffer.c (Fgenerate_new_buffer_name):
15158 Use EMACS_INT for count, not int.
15159 (advance_to_char_boundary): Return EMACS_INT, not int.
15161 * data.c (Qcompiled_function): Now static.
15163 * window.c (window_body_lines): Now static.
15165 * image.c (gif_load): Rename local to avoid shadowing.
15167 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
15168 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
15169 * alloc.c (make_save_value): Integer argument is now of type
15170 ptrdiff_t, not int.
15171 (mark_object): Use ptrdiff_t, not int.
15172 * lisp.h (pD): New macro.
15173 * print.c (print_object): Use it.
15175 * alloc.c: Use EMACS_INT, not int, to count objects.
15176 (total_conses, total_markers, total_symbols, total_vector_size)
15177 (total_free_conses, total_free_markers, total_free_symbols)
15178 (total_free_floats, total_floats, total_free_intervals)
15179 (total_intervals, total_strings, total_free_strings):
15180 Now EMACS_INT, not int. All uses changed.
15181 (Fgarbage_collect): Compute overall total using a double, so that
15182 integer overflow is less likely to be a problem. Check for overflow
15183 when converting back to an integer.
15184 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
15185 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
15186 These were 'int' variables that could overflow on 64-bit hosts;
15187 they were never used, so remove them instead of repairing them.
15188 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
15189 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
15190 Previously, this ceilinged at INT_MAX, but that doesn't work on
15192 (allocate_pseudovector): Don't use EMACS_INT when int would do.
15194 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
15195 (allocate_vectorlike): Check for ptrdiff_t overflow.
15196 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
15197 when a (possibly-narrower) signed value would do just as well.
15198 We prefer using signed arithmetic, to avoid comparison confusion.
15200 * alloc.c: Catch some string size overflows that we were missing.
15201 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
15202 for convenience in STRING_BYTES_MAX.
15203 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
15204 The definition here is exact; the one in lisp.h was approximate.
15205 (allocate_string_data): Check for string overflow. This catches
15206 some instances we weren't catching before. Also, it catches
15207 size_t overflow on (unusual) hosts where SIZE_MAX <= min
15208 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
15209 and ptrdiff_t and EMACS_INT are both 64 bits.
15211 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
15212 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.

15656 * character.h (MAYBE_UNIFY_CHAR):
15657 * charset.c (maybe_unify_char):
15658 * keyboard.c (read_char, reorder_modifiers):
15659 XINT -> XFASTINT, since the integer must be nonnegative.
15660 * ftfont.c (ftfont_spec_pattern):
15661 * keymap.c (access_keymap, silly_event_symbol_error):
15662 XUINT -> XFASTINT, since the integer must be nonnegative.
15663 (Fsingle_key_description, preferred_sequence_p): XUINT -> XINT,
15664 since it makes no difference and we prefer signed.
15665 * keyboard.c (record_char): Use XUINT when all the neighbors do.
15666 (access_keymap): NATNUMP -> INTEGERP, since the integer must be

15713 code. Minor doc-string fixes.
15715 2011-06-06 Paul Eggert <eggert@cs.ucla.edu>
15717 * alloc.c (memory_full) [SYSTEM_MALLOC]: Port to MacOS (Bug#8800).
15718 Do not assume that spare memory exists; that assumption is valid
15719 only if SYSTEM_MALLOC.
15720 (LARGE_REQUEST): New macro, so that the issue of large requests
15721 is separated from the issue of spare memory.
15723 2011-06-05 Andreas Schwab <schwab@linux-m68k.org>
15725 * editfns.c (Fformat): Correctly handle zero flag with hexadecimal

15751 New error handlers.
15752 (x_clipboard_manager_save_frame, x_clipboard_manager_save_all):
15753 Obey Vx_select_enable_clipboard_manager. Catch errors in
15754 x_clipboard_manager_save (Bug#8779).
15755 (Vx_select_enable_clipboard_manager): New variable.
15756 (x_get_foreign_selection): Reduce scope of x_catch_errors (Bug#8790).
15758 2011-06-04 Dan Nicolaescu <dann@ics.uci.edu>
15760 * emacs.c (main): Warn when starting a GTK emacs in daemon mode.
15762 2011-06-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15764 * fringe.c (update_window_fringes): Don't update overlay arrow bitmap
15765 in the current matrix if keep_current_p is non-zero.

15771 2011-06-03 Eli Zaretskii <eliz@gnu.org>
15773 Support bidi reordering of text covered by display properties.
15775 * bidi.c (bidi_copy_it): Use offsetof instead of emulating it.
15776 (bidi_fetch_char, bidi_fetch_char_advance): New functions.
15777 (bidi_cache_search, bidi_cache_iterator_state)
15778 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
15779 (bidi_level_of_next_char, bidi_move_to_visually_next):
15780 Support character positions inside a run of characters covered by a
15782 (bidi_paragraph_init, bidi_resolve_explicit_1)
15783 (bidi_level_of_next_char): Call bidi_fetch_char and
15784 bidi_fetch_char_advance instead of FETCH_CHAR and
15785 FETCH_CHAR_ADVANCE.

15787 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
15789 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
15790 instead of using explicit *_CHAR codes.
15791 (bidi_resolve_explicit, bidi_resolve_weak):
15792 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
15793 bidirectional text is supported only in multibyte buffers.
15794 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
15795 it to initialize the frame_window_p member of struct bidi_it.
15796 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
15797 (bidi_resolve_explicit, bidi_resolve_weak)

15799 bidi_it->nchars is non-positive.
15800 (bidi_level_of_next_char): Don't try to lookup the cache for the
15801 next/previous character if nothing is cached there yet, or if we
15802 were just reseat()'ed to a new position.
15804 * xdisp.c (set_cursor_from_row): Set start and stop points
15805 according to the row's direction when priming the loop that looks
15806 for the glyph on which to display cursor.
15807 (single_display_spec_intangible_p): Function deleted.
15808 (display_prop_intangible_p): Reimplement to call
15809 handle_display_spec instead of single_display_spec_intangible_p.
15810 Accept 3 additional arguments needed by handle_display_spec.
15811 This fixes incorrect cursor motion across display property with complex
15812 values: lists, `(when COND...)' forms, etc.
15813 (single_display_spec_string_p): Support property values that are
15814 lists with the argument STRING its top-level element.
15815 (display_prop_string_p): Fix the condition for processing a
15816 property that is a list to be consistent with handle_display_spec.
15817 (handle_display_spec): New function, refactored from the
15818 last portion of handle_display_prop.
15819 (compute_display_string_pos): Accept additional argument
15820 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
15821 value of a `display' property is a "replacing spec".
15822 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
15823 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
15824 the display property, but just return a value indicating whether
15825 the display property will replace the characters it covers.
15826 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
15827 frame_window_p members of struct bidi_it.
15828 (compute_display_string_pos, compute_display_string_end):
15830 (push_it): Accept second argument POSITION, where pop_it should
15831 jump to continue iteration.
15832 (reseat_1): Initialize bidi_it.disp_pos.
15834 * keyboard.c (adjust_point_for_property): Adjust the call to
15835 display_prop_intangible_p to its new signature.
15837 * dispextern.h (struct bidi_it): New member frame_window_p.
15838 (bidi_init_it): Update prototypes.
15839 (display_prop_intangible_p): Update prototype.
15840 (compute_display_string_pos, compute_display_string_end):

15842 (struct bidi_it): New members nchars and disp_pos. ch_len is now
15845 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
15847 Malloc failure behavior now depends on size of allocation.
15848 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
15849 * lisp.h: Change signatures accordingly.
15850 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
15851 All callers changed. (Bug#8762)
15853 * gnutls.c: Use Emacs's memory allocators.
15854 Without this change, the gnutls library would invoke malloc etc.
15855 directly, which causes problems on non-SYNC_INPUT hosts, and which
15856 runs afoul of improving memory_full behavior. (Bug#8761)
15857 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
15858 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
15859 xfree instead of the default malloc, realloc, free.
15860 (Fgnutls_boot): No need to check for memory allocation failure,
15861 since xmalloc does that for us.
15863 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
15864 * category.c (hash_get_category_set):
15865 * ccl.c (ccl_driver):

15877 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
15878 (Fsxhash, Fgethash, Fputhash, Fmaphash):
15879 * image.c (make_image, search_image_cache, lookup_image)
15880 (xpm_put_color_table_h):
15881 * lisp.h (struct Lisp_Hash_Table):
15882 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
15883 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
15884 for hashes and hash indexes, instead of 'unsigned' and 'int'.
15885 * alloc.c (allocate_vectorlike):
15886 Check for overflow in vector size calculations.
15887 * ccl.c (ccl_driver):
15888 Check for overflow when converting EMACS_INT to int.
15889 * fns.c, image.c: Remove unnecessary static decls that would otherwise
15890 need to be updated by these changes.
15891 * fns.c (make_hash_table, maybe_resize_hash_table):
15892 Check for integer overflow with large hash tables.
15893 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
15894 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
15895 (SXHASH_REDUCE): New macro.
15896 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
15897 Use it instead of discarding useful hash info with large hash values.
15898 (sxhash_float): New function.
15899 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
15900 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
15901 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
15902 Rewrite to use FIXNUM_BITS, as this simplifies things.
15903 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
15904 Adjust signatures to match updated version of code.
15905 (consing_since_gc): Now EMACS_INT, since a single hash table can
15906 use more than INT_MAX bytes.
15908 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
15910 Make it possible to build with GCC-4.6+ -O2 -flto.
15912 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
15914 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
15916 * minibuf.c (get_minibuffer, read_minibuf_unwind):
15917 Call minibuffer-inactive-mode.
15919 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
15921 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
15922 Update dependencies.
15924 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
15926 * data.c (init_data): Remove code for UTS, this system is not
15929 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
15931 Don't force ./temacs to start in terminal mode.
15933 * frame.c (make_initial_frame): Initialize faces in all cases, not
15934 only when CANNOT_DUMP is defined.
15935 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
15937 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
15939 * dispnew.c (add_window_display_history): Use const for the string
15940 pointer. Remove declaration, not needed.
15942 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
15944 Use 'inline', not 'INLINE'.
15945 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
15946 * alloc.c, fontset.c (INLINE): Remove.
15947 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
15948 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
15949 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
15950 * gmalloc.c (register_heapinfo): Use inline unconditionally.
15951 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
15953 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
15955 Make it possible to run ./temacs.
15957 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
15958 syms_of_callproc does the same thing. Remove test for
15959 "initialized", do it in the caller.
15960 * emacs.c (main): Avoid calling set_initial_environment when dumping.
15962 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
15964 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
15965 (read_minibuf): Use get_minibuffer.
15966 (syms_of_minibuf): Use DEFSYM.
15967 (Qmetadata): New var.
15968 * data.c (Qbuffer): Don't make it static.
15969 (syms_of_data): Use DEFSYM.
15971 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
15973 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
15974 (CCL_CODE_MIN): New macro.
15976 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
15978 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
15980 * eval.c (Qdebug): Now static.
15981 * lisp.h (Qdebug): Remove decl. This reverts a part of the
15982 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
15983 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
15985 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
15987 * image.c: Various fixes to ImageMagick code comments.
15988 (Fimagemagick_types): Doc fix.
15990 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
15992 Minor fixes prompted by GCC 4.6.0 warnings.
15994 * xselect.c (converted_selections, conversion_fail_tag): Now static.
15996 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
15997 (x_clipboard_manager_save_all): Move extern decl to ...
15998 * xterm.h: ... here, so that it can be checked for consistency.
16000 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
16002 * xselect.c (x_clipboard_manager_save_frame)
16003 (x_clipboard_manager_save_all): New functions.
16004 (Fx_clipboard_manager_save): Lisp function deleted.
16006 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
16007 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
16009 * xterm.h: Update prototype.
16011 2011-05-28 William Xu <william.xwl@gmail.com>
16013 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
16014 exiting (Bug#8239).
16016 2011-05-28 Jim Meyering <meyering@redhat.com>
16018 Avoid a sign-extension bug in crypto_hash_function.
16019 * fns.c (to_uchar): Define.
16020 (crypto_hash_function): Use it to convert some newly-signed
16021 variables to unsigned, to avoid sign-extension bugs. For example,
16022 without this change, (md5 "truc") would evaluate to
16023 45723a2aff78ff4fff7fff1114760e62 rather than the expected
16024 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
16025 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
16027 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
16029 Integer overflow fixes.
16031 * dbusbind.c: Serial number integer overflow fixes.
16032 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
16033 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
16034 to hold a serial number that is too large for a fixnum.
16035 (Fdbus_method_return_internal, Fdbus_method_error_internal):
16036 Check for serial numbers out of range. Decode any serial number
16037 that was so large that it became a float. (Bug#8722)
16039 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
16040 (Fdbus_call_method, Fdbus_call_method_asynchronously):
16041 Use XFASTINT rather than XUINT when numbers are nonnegative.
16042 (xd_append_arg, Fdbus_method_return_internal):
16043 (Fdbus_method_error_internal): Likewise. Also, for unsigned
16044 arguments, check that Lisp number is nonnegative, rather than
16045 silently wrapping negative numbers around. (Bug#8722)
16046 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
16049 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
16051 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
16053 ccl: Add integer overflow checks.
16054 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
16055 (IN_INT_RANGE): New macros.
16056 (ccl_driver): Use them to check for integer overflow when
16057 decoding a CCL program. Many of the new checks are whether XINT (x)
16058 fits in int; it doesn't always, on 64-bit hosts. The new version
16059 doesn't catch all possible integer overflows, but it's an
16060 improvement. (Bug#8719)
16062 * alloc.c (make_event_array): Use XINT, not XUINT.
16063 There's no need for unsigned here.
16065 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
16066 This follows up to the 2011-05-06 change that substituted uintptr_t
16067 for EMACS_INT. This case wasn't caught back then.
16069 Rework Fformat to avoid integer overflow issues.
16070 * editfns.c: Include <float.h> unconditionally, as it's everywhere
16071 now (part of C89). Include <verify.h>.
16072 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
16073 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
16074 (Fformat): Avoid the prepass trying to compute sizes; it was only
16075 approximate and thus did not catch overflow reliably. Instead, walk
16076 through the format just once, formatting and computing sizes as we go,
16077 checking for integer overflow at every step, and allocating a larger
16078 buffer as needed. Keep track separately whether the format is
16079 multibyte. Keep only the most-recently calculated precision, rather
16080 than them all. Record whether each argument has been converted to
16081 string. Use EMACS_INT, not int, for byte and char and arg counts.
16082 Support field widths and precisions larger than INT_MAX. Avoid
16083 sprintf's undefined behavior with conversion specifications such as %#d
16084 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
16085 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
16086 formatting out-of-range floating point numbers with int
16087 formats. (Bug#8668)
16089 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
16091 * data.c: Avoid integer truncation in expressions involving floats.
16092 * data.c: Include <intprops.h>.
16093 (arith_driver): When there's an integer overflow in an expression
16094 involving floating point, convert the integers to floating point
16095 so that the resulting value does not suffer from catastrophic
16096 integer truncation. For example, on a 64-bit host (* 4
16097 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
16098 Do not rely on undefined behavior after integer overflow.
16100 merge count_size_as_multibyte, parse_str_to_multibyte
16101 * character.c, character.h (count_size_as_multibyte):
16102 Rename from parse_str_to_multibyte; all uses changed.
16103 Check for integer overflow.
16104 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
16105 since it's now a duplicate of the other. This is more of
16106 a character than a buffer op, so better that it's in character.c.
16107 * fns.c, print.c: Adjust to above changes.
16109 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
16111 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
16113 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
16115 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
16116 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
16117 (x_clipboard_manager_save): Now static.
16118 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
16120 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
16121 (crypto_hash_function): Now static.
16122 Fix pointer signedness problems. Avoid unnecessary initializations.
16124 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
16126 * termhooks.h (Vselection_alist): Make it terminal-local.
16128 * terminal.c (create_terminal): Initialize it.
16130 * xselect.c: Support for clipboard managers.
16131 (Vselection_alist): Move to termhooks.h as terminal-local var.
16132 (LOCAL_SELECTION): New macro.
16133 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
16134 (symbol_to_x_atom): Remove gratuitous arg.
16135 (x_handle_selection_request, lisp_data_to_selection_data)
16136 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
16137 (x_own_selection, x_get_local_selection, x_convert_selection):
16138 New arg, specifying work frame. Use terminal-local Vselection_alist.
16139 (some_frame_on_display): Delete unused function.
16140 (Fx_own_selection_internal, Fx_get_selection_internal)
16141 (Fx_disown_selection_internal, Fx_selection_owner_p)
16142 (Fx_selection_exists_p): New optional frame arg.
16143 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
16144 (x_handle_selection_clear): Don't treat other terminals with the
16145 same keyboard specially. Use the terminal-local Vselection_alist.
16146 (x_clear_frame_selections): Use Frun_hook_with_args.
16148 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
16150 * xterm.h: Add support for those atoms.
16152 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
16154 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
16155 (converted_selections, conversion_fail_tag): New global variables.
16156 (x_selection_request_lisp_error): Free the above.
16157 (x_get_local_selection): Remove unnecessary code.
16158 (x_reply_selection_request): Args changed; handle arbitrary array
16159 of converted selections stored in converted_selections.
16160 Separate the XChangeProperty and SelectionNotify steps.
16161 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
16162 (x_convert_selection): New function.
16163 (x_handle_selection_event): Simplify.
16164 (x_get_foreign_selection): Don't ignore incoming requests while
16165 waiting for an answer; this will fail when we implement
16166 SAVE_TARGETS, and seems unnecessary anyway.
16167 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
16168 (Vx_sent_selection_functions): Doc fix.
16170 2011-05-26 Leo Liu <sdl.web@gmail.com>
16172 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
16174 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16176 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
16178 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
16179 for fringe update if it has periodic bitmap.
16180 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
16181 and fringe_bitmap_periodic_p.
16183 * fringe.c (get_fringe_bitmap_data): New function.
16184 (draw_fringe_bitmap_1, update_window_fringes): Use it.
16185 (update_window_fringes): Record periodicity of fringe bitmap in glyph
16186 row. Mark glyph row for fringe update if periodicity changed.
16188 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
16189 for fringe update unless it has periodic bitmap.
16191 2011-05-25 Kenichi Handa <handa@m17n.org>
16193 * xdisp.c (get_next_display_element): Set correct it->face_id for
16194 a static composition.
16196 2011-05-24 Leo Liu <sdl.web@gmail.com>
16199 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
16201 * fns.c (crypto_hash_function, Fsha1): New function.
16202 (Fmd5): Use crypto_hash_function.
16203 (syms_of_fns): Add Ssha1.
16205 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
16207 * gnutls.c: Remove unused macros.
16208 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
16209 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
16210 Remove macros that are defined and never used.
16211 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
16213 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
16215 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
16216 (Fx_get_selection_internal): Minor cleanup.
16217 (Fx_own_selection_internal): Rename arguments for consistency with
16220 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
16222 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
16224 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
16226 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
16228 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16230 * dispnew.c (scrolling_window): Don't exclude the case that the
16231 last enabled row in the desired matrix touches the bottom boundary.
16233 2011-05-21 Glenn Morris <rgm@gnu.org>
16235 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
16236 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
16237 and add some more files.
16239 2011-05-20 Eli Zaretskii <eliz@gnu.org>
16241 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
16242 report_file_error introduced by the change from 2011-05-07.
16244 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
16246 * systime.h (Time): Define only if emacs is defined.
16247 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
16248 where the include path doesn't have X11/X.h by default. See
16249 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
16251 2011-05-20 Kenichi Handa <handa@m17n.org>
16253 * composite.c (find_automatic_composition): Fix previous change.
16255 2011-05-20 Glenn Morris <rgm@gnu.org>
16257 * lisp.mk: New file, split from Makefile.in.
16258 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
16259 (shortlisp): Remove.
16260 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
16262 2011-05-19 Glenn Morris <rgm@gnu.org>
16264 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
16265 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
16266 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
16267 (lisp): Set the order to that of loadup.el.
16268 (shortlisp): Make it a copy of $lisp.
16269 (SOME_MACHINE_LISP): Remove.
16270 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
16271 Use just $shortlisp, not $SOME_MACHINE_LISP too.
16273 2011-05-18 Kenichi Handa <handa@m17n.org>
16275 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
16276 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
16277 (find_automatic_composition): Mostly rewrite for efficiency.
16279 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
16281 * makefile.w32-in: Update dependencies.
16283 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
16285 * menu.c: Include limits.h (fixes the MS-Windows build broken by
16286 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
16288 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
16290 Fix some integer overflow issues, such as string length overflow.
16292 * insdel.c (count_size_as_multibyte): Check for string overflow.
16294 * character.c (lisp_string_width): Check for string overflow.
16295 Use EMACS_INT, not int, for string indexes and lengths; in
16296 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
16297 the resulting string length overflows an EMACS_INT; instead,
16298 report a string overflow if no precision given. When checking for
16299 precision exhaustion, use a check that cannot possibly have
16300 integer overflow. (Bug#8675)
16301 * character.h (lisp_string_width): Adjust to new signature.
16303 * alloc.c (string_overflow): New function.
16304 (Fmake_string): Use it. This doesn't change behavior, but saves
16305 a few bytes and will simplify future changes.
16306 * character.c (string_escape_byte8): Likewise.
16307 * lisp.h (string_overflow): New decl.
16309 Fixups, following up to the user-interface timestamp change.
16310 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
16311 for UI timestamps, instead of unsigned long.
16312 * msdos.c (mouse_get_pos): Likewise.
16313 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
16314 * w32gui.h (Time): Define by including "systime.h" rather than by
16315 declaring it ourselves. (Bug#8664)
16317 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
16318 * image.c (clear_image_cache): Likewise.
16320 * term.c (term_mouse_position): Don't assume time_t wraparound.
16322 Be more systematic about user-interface timestamps.
16323 Before, the code sometimes used 'Time', sometimes 'unsigned long',
16324 and sometimes 'EMACS_UINT', to represent these timestamps.
16325 This change causes it to use 'Time' uniformly, as that's what X uses.
16326 This makes the code easier to follow, and makes it easier to catch
16327 integer overflow bugs such as Bug#8664.
16328 * frame.c (Fmouse_position, Fmouse_pixel_position):
16329 Use Time, not unsigned long, for user-interface timestamps.
16330 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
16331 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
16332 * keyboard.h (last_event_timestamp): Likewise.
16333 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
16334 * menu.h (xmenu_show): Likewise.
16335 * term.c (term_mouse_position): Likewise.
16336 * termhooks.h (struct input_event.timestamp): Likewise.
16337 (struct terminal.mouse_position_hook): Likewise.
16338 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
16339 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
16340 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
16341 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
16342 what it was before.
16343 * menu.h, termhooks.h: Include "systime.h", for Time.
16345 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
16346 Don't assume that the difference between two unsigned long values
16347 can fit into an integer. At this point, we know button_down_time
16348 <= event->timestamp, so the difference must be nonnegative, so
16349 there's no need to cast the result if double-click-time is
16350 nonnegative, as it should be; check that it's nonnegative, just in
16351 case. This bug is triggered when events are more than 2**31 ms
16352 apart (about 25 days). (Bug#8664)
16354 * xselect.c (last_event_timestamp): Remove duplicate decl.
16355 (x_own_selection): Remove needless cast to unsigned long.
16357 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
16358 that always fit in int. Use a sentinel instead of a counter, to
16359 avoid a temp and to allay GCC's concerns about possible int overflow.
16360 * frame.h (struct frame): Use int for menu_bar_items_used
16361 instead of EMACS_INT, since it always fits in int.
16363 * menu.c (grow_menu_items): Check for int overflow.
16365 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
16367 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
16368 Before, the code was not consistent. These values cannot exceed
16369 2**31 - 1 so there's no need to make them unsigned.
16370 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
16371 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
16372 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
16374 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
16376 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
16377 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
16378 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
16379 presumably because the widths might not match.
16381 * window.c (size_window): Avoid needless test at loop start.
16383 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
16385 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
16387 2011-05-12 Drew Adams <drew.adams@oracle.com>
16389 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
16391 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16393 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
16394 `width' to `bar_area_x' and `bar_area_width', respectively.
16395 (x_scroll_run): Take account of fringe background extension.
16397 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
16398 Rename local vars `left' and `width' to `bar_area_x' and
16399 `bar_area_width', respectively.
16400 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
16401 background extension.
16403 2011-05-10 Jim Meyering <meyering@redhat.com>
16405 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
16407 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
16409 * image.c (Finit_image_library): Return t for built-in image types,
16410 like pbm and xbm. (Bug#8640)
16412 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
16414 * w32menu.c (set_frame_menubar): Fix submenu allocation.
16416 2011-05-07 Eli Zaretskii <eliz@gnu.org>
16418 * w32console.c (Fset_screen_color): Doc fix.
16419 (Fget_screen_color): New function.
16420 (syms_of_ntterm): Defsubr it.
16422 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
16423 unlink the temporary file if Fcall_process didn't create it in the
16425 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
16426 child process will be redirected to a file specified with `:file'.
16427 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
16428 cue to call_process_cleanup not to close that handle.
16430 2011-05-07 Ben Key <bkey76@gmail.com>
16432 * makefile.w32-in: The bootstrap-temacs rule now makes use of
16433 one of two shell specific rules, either bootstrap-temacs-CMD or
16434 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
16435 to the previous implementation of the bootstrap-temacs rule.
16436 The bootstrap-temacs-CMD rule is similar to the previous
16437 implementation of the bootstrap-temacs rule except that it
16438 makes use of the ESC_CFLAGS variable instead of the CFLAGS
16441 These changes, along with some changes to nt/configure.bat,
16442 nt/gmake.defs, and nt/nmake.defs, are required to extend my
16443 earlier fix to add support for --cflags and --ldflags options
16444 that include quotes so that it works whether make uses cmd or
16447 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
16449 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
16450 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
16452 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
16453 a string. Handle both cases.
16454 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
16455 (Fdbus_register_method): Use Qinvalid_function.
16457 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
16459 * makefile.w32-in: Update dependencies.
16460 (LISP_H): Add inttypes.h and stdin.h.
16461 (PROCESS_H): Add unistd.h.
16463 2011-05-06 Eli Zaretskii <eliz@gnu.org>
16465 * lread.c: Include limits.h (fixes the MS-Windows build broken by
16466 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
16468 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
16470 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
16472 * term.c (vfatal): Remove stray call to va_end.
16473 It's not needed and the C Standard doesn't allow it here anyway.
16475 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
16476 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
16478 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
16481 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
16483 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
16485 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
16487 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
16489 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
16491 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
16492 * charset.c (Fdefine_charset_internal): Don't initialize
16493 charset.code_space[15]. The value was garbage, on hosts with
16494 32-bit int (Bug#8600).
16496 * lread.c (read_integer): Be more consistent with string-to-number.
16497 Use string_to_number to do the actual conversion; this avoids
16498 rounding errors and fixes some other screwups. Without this fix,
16499 for example, #x1fffffffffffffff was misread as -2305843009213693952.
16500 (digit_to_number): Move earlier, for benefit of read_integer.
16501 Return -1 if the digit is out of range for the base, -2 if it is
16502 not a digit in any supported base. (Bug#8602)
16504 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
16506 * dispnew.c (scrolling_window): Return 1 if we scrolled,
16507 to match comment at start of function. This also removes a
16508 GCC warning about overflow in a 32+64-bit port.
16510 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
16512 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
16513 Reported by Stefan Monnier in
16514 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
16515 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
16516 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
16518 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
16519 (EMACS_UINTPTR): Likewise, with uintptr_t.
16521 * lisp.h: Prefer 64-bit EMACS_INT if available.
16522 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
16523 on 32-bit hosts that have 64-bit int, so that they can access
16525 However, temporarily disable this change unless the temporary
16526 symbol WIDE_EMACS_INT is defined.
16528 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
16530 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
16531 This removes an assumption that EMACS_INT and long are the same
16532 width as pointers. The assumption is true for Emacs porting targets
16533 now, but we want to make other targets possible.
16534 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
16535 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
16536 In the rest of the code, change types of integers that hold casted
16537 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
16538 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
16539 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
16540 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
16541 No need to cast type when ORing.
16542 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
16543 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
16544 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
16545 assume EMACS_INT is the same width as char *.
16546 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
16547 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
16548 Remove no-longer-needed casts.
16549 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
16550 (xg_tool_bar_help_callback, xg_make_tool_item):
16551 Use EMACS_INTPTR to hold an integer
16552 that will be cast to void *; this can avoid a GCC warning
16553 if EMACS_INT is not the same width as void *.
16554 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
16555 * xdisp.c (display_echo_area_1, resize_mini_window_1):
16556 (current_message_1, set_message_1):
16557 Use a local to convert to proper width without a cast.
16558 * xmenu.c (dialog_selection_callback): Likewise.
16560 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
16561 Also, don't assume VALBITS / RAND_BITS is less than 5,
16562 and don't rely on undefined behavior when shifting a 1 left into
16564 * lisp.h (get_random): Change signature to match.
16566 * lread.c (hash_string): Use size_t, not int, for hash computation.
16567 Normally we prefer signed values; but hashing is special, because
16568 it's better to use unsigned division on hash table sizes so that
16569 the remainder is nonnegative. Also, size_t is the natural width
16570 for hashing into memory. The previous code used 'int', which doesn't
16571 retain enough info to hash well into very large tables.
16572 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
16574 * dbusbind.c: Don't possibly lose pointer info when converting.
16575 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
16576 Use XPNTR rather than XHASH, so that the high-order bits of
16577 the pointer aren't lost when converting through void *.
16579 * eval.c (Fautoload): Don't double-shift a pointer.
16581 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
16583 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
16585 * gnutls.c (DEF_GNUTLS_FN):
16586 * image.c (DEF_IMGLIB_FN): Make function pointers static.
16588 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
16590 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
16593 2011-05-05 Eli Zaretskii <eliz@gnu.org>
16595 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
16596 New version that can reserve upto 2GB of heap space.
16598 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
16600 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
16602 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
16604 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
16605 `gnutls_certificate_set_x509_key_file'.
16607 2011-05-05 Juanma Barranquero <lekktu@gmail.com>

16610 Update dependencies.
16612 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
16614 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
16615 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
16616 Remove unused parameter `fildes'.
16617 * process.c (read_process_output, send_process): Don't pass it.
16619 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
16621 Fix previous change: the library cache is defined in w32.c.
16622 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
16623 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
16625 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
16627 Implement dynamic loading of GnuTLS on Windows.
16629 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
16630 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
16631 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
16634 * gnutls.c (Qgnutls_dll): Define.

16642 (emacs_gnutls_write, emacs_gnutls_read)
16643 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
16644 (Fgnutls_available_p): New function.
16645 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.

16655 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
16657 * w32.c (QCloaded_from, Vlibrary_cache): Define.
16658 (w32_delayed_load): Move from image.c. When loading a library, record
16659 its filename in the :loaded-from property of the library id.
16660 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
16661 Initialize and staticpro them.
16662 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
16664 * process.c: Include lisp.h before w32.h, not after.
16665 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
16666 instead of gnutls_record_check_pending.
16668 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
16670 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
16672 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
16673 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
16676 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
16678 * xterm.c (x_set_frame_alpha): Do not set property on anything
16679 else than FRAME_X_OUTER_WINDOW (Bug#8608).
16681 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
16683 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
16685 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
16687 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
16688 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)

16702 (wait_for_termination, interruptible_wait_for_termination):
16703 Move after wait_for_termination_1.
16705 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
16707 * sysdep.c (interruptible_wait_for_termination): New function
16708 which is like wait_for_termination, but allows keyboard
16711 * callproc.c (Fcall_process): Add (:file "file") as an option for
16713 (Fcall_process_region): Ditto.
16715 2011-04-30 Eli Zaretskii <eliz@gnu.org>
16717 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
16718 rather than `XVECTOR (FOO)->size'.
16720 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
16721 inttypes.h, as a gnulib replacement is used if it not available in
16724 2011-04-21 Eli Zaretskii <eliz@gnu.org>
16726 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
16727 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
16728 of MOST_POSITIVE_FIXNUM. (Bug#8528)
16730 * coding.c (coding_alloc_by_realloc): Error out if destination
16731 will grow beyond MOST_POSITIVE_FIXNUM.
16732 (decode_coding_emacs_mule): Abort if there isn't enough place in
16733 charbuf for the composition carryover bytes. Reserve an extra
16734 space for up to 2 characters produced in a loop.
16735 (decode_coding_iso_2022): Abort if there isn't enough place in
16736 charbuf for the composition carryover bytes.
16738 2011-04-21 Eli Zaretskii <eliz@gnu.org>
16740 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
16741 aborting when %lld or %lll format is passed.
16742 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
16743 %llo or %llx format is passed. (Bug#8545)
16745 * window.c (window_scroll_line_based): Use a marker instead of
16746 simple variables to record original value of point. (Bug#7952)
16748 * doprnt.c (doprnt): Fix the case where a multibyte sequence
16749 produced by %s or %c overflows available buffer space. (Bug#8545)
16751 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
16753 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
16754 (SIZE_MAX): Move defn after all includes, as they might #define it.
16756 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
16758 * w32.c (init_environment): Warn about defaulting HOME to C:\.

16762 * keyboard.c (Qdelayed_warnings_hook): Define.
16763 (command_loop_1): Run `delayed-warnings-hook'
16764 if Vdelayed_warnings_list is non-nil.
16765 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
16766 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
16768 2011-04-28 Eli Zaretskii <eliz@gnu.org>
16770 * doprnt.c (doprnt): Don't return value smaller than the buffer
16771 size if the message was truncated. (Bug#8545).
16773 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
16775 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
16776 (Fx_window_property): #if-0 the whole functions, not just the bodies.
16778 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
16780 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
16782 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
16784 * makefile.w32-in: Update dependencies.
16786 2011-04-27 Eli Zaretskii <eliz@gnu.org>
16788 Improve `doprnt' and its usage. (Bug#8545)
16789 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
16790 `format_end'. Remove support for %l as a conversion specifier.
16791 Don't use xrealloc. Improve diagnostics when the %l size modifier
16792 is used. Update the commentary.
16794 * eval.c (verror): Simplify calculation of size_t.
16796 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
16799 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
16801 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
16804 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
16806 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
16807 This makes this file independent of the recent pseudovector change.
16809 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
16811 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
16813 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
16814 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
16815 Remove unused local.
16816 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
16818 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
16819 GCC 4.6.0 optimizes based on type-based alias analysis.
16820 For example, if b is of type struct buffer * and v of type struct
16821 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
16822 != &v->size, and therefore "v->size = 1; b->size = 2; return
16823 v->size;" must therefore return 1. This assumption is incorrect
16824 for Emacs, since it type-puns struct Lisp_Vector * with many other
16825 types. To fix this problem, this patch adds a new type struct
16826 vectorlike_header that documents the constraints on layout of vectors
16827 and pseudovectors, and helps optimizing compilers not get fooled
16828 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
16829 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
16830 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
16832 (XSETPVECTYPE): Rewrite in terms of new macro.
16833 (XSETPVECTYPESIZE): New macro, specifying both type and size.
16834 This is a bit clearer, and further avoids the possibility of
16835 undesirable aliasing.
16836 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
16837 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
16838 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
16839 since Lisp_Subr is a special case (no "next" field).
16840 (ASIZE): Now uses header.size rather than size.
16841 All previous uses of XVECTOR (foo)->size replaced to use this macro,
16842 to avoid the hassle of writing XVECTOR (foo)->header.size.
16843 (struct vectorlike_header): New type.
16844 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
16845 object, to help avoid aliasing.
16846 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
16847 (SUBRP): Likewise, since Lisp_Subr is a special case.
16848 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
16849 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
16850 (struct Lisp_Hash_Table): Combine first two members into a single
16851 struct vectorlike_header member. All uses of "size" and "next" members
16852 changed to be "header.size" and "header.next".
16853 * buffer.h (struct buffer): Likewise.
16854 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
16855 * frame.h (struct frame): Likewise.
16856 * process.h (struct Lisp_Process): Likewise.
16857 * termhooks.h (struct terminal): Likewise.
16858 * window.c (struct save_window_data, struct saved_window): Likewise.
16859 * window.h (struct window): Likewise.
16860 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
16861 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
16862 * buffer.c (init_buffer_once): Likewise.
16863 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
16865 * process.c (Fformat_network_address): Use local var for size,
16868 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
16870 Make the Lisp reader and string-to-float more consistent (Bug#8525)
16871 * data.c (atof): Remove decl; no longer used or needed.
16872 (digit_to_number): Move to lread.c.
16873 (Fstring_to_number): Use new string_to_number function, to be
16874 consistent with how the Lisp reader treats infinities and NaNs.
16875 Do not assume that floating-point numbers represent EMACS_INT
16876 without losing information; this is not true on most 64-bit hosts.
16877 Avoid double-rounding errors, by insisting on integers when
16878 parsing non-base-10 numbers, as the documentation specifies.
16879 * lisp.h (string_to_number): New decl, replacing ...
16880 (isfloat_string): Remove.
16881 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
16882 (read1): Do not accept +. and -. as integers; this
16883 appears to have been a coding error. Similarly, do not accept
16884 strings like +-1e0 as floating point numbers. Do not report
16885 overflow for integer overflows unless the base is not 10 which
16886 means we have no simple and reliable way to continue.
16887 Break out the floating-point parsing into a new
16888 function string_to_number, so that Fstring_to_number parses
16889 floating point numbers consistently with the Lisp reader.
16890 (digit_to_number): Move here from data.c. Make it static inline.
16891 (E_CHAR, EXP_INT): Remove, replacing with ...
16892 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
16893 (string_to_number): New function, replacing isfloat_string.
16894 This function checks for valid syntax and produces the resulting
16895 Lisp float number too. Rework it so that string-to-number
16896 no longer mishandles examples like "1.0e+". Use strtoumax,
16897 so that overflow for non-base-10 numbers is reported only when
16898 there's no portable and simple way to convert to floating point.
16900 * textprop.c (set_text_properties_1): Rewrite for clarity,
16901 and to avoid GCC warning about integer overflow.
16903 * intervals.h (struct interval): Use EMACS_INT for members
16904 where EMACS_UINT might cause problems. See
16905 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
16906 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
16907 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
16909 (offset_intervals): Tell GCC not to worry about length overflow
16910 when negating a negative length.
16912 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
16913 (overrun_check_free): Likewise.
16915 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
16916 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
16919 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
16920 (gnutls_make_error): Rename local to avoid shadowing.
16921 (gnutls_emacs_global_deinit): ifdef out; not used.
16922 (Fgnutls_boot): Use const for pointer to readonly storage.
16923 Comment out unused local. Fix pointer signedness problems.
16925 * lread.c (openp): Don't stuff size_t into an 'int'.
16926 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
16927 about possible signed overflow.
16929 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
16930 (GDK_KEY_g): Don't define if already defined.
16931 (xg_prepare_tooltip): Avoid pointer signedness problem.
16932 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
16934 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
16935 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
16937 * xfns.c (Fx_window_property): Simplify a bit,
16938 to make a bit faster and to avoid GCC 4.6.0 warning.
16939 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
16941 * fns.c (internal_equal): Don't assume size_t fits in int.
16943 * alloc.c (compact_small_strings): Tighten assertion a little.
16945 Replace pEd with more-general pI, and fix some printf arg casts.
16946 * lisp.h (pI): New macro, generalizing old pEd macro to other
16947 conversion specifiers. For example, use "...%"pI"d..." rather
16948 than "...%"pEd"...".
16949 (pEd): Remove. All uses replaced with similar uses of pI.
16950 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
16951 * alloc.c (check_pure_size): Don't overflow by converting size to int.
16952 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.

16955 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
16956 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
16958 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
16959 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
16960 * print.c (safe_debug_print, print_object): Likewise.
16961 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
16963 Use pI instead of if-then-else-abort. Use %p to avoid casts,
16964 avoiding the 0 flag, which is not portable.
16965 * process.c (Fmake_network_process): Use pI to avoid cast.
16966 * region-cache.c (pp_cache): Likewise.
16967 * xdisp.c (decode_mode_spec): Likewise.
16968 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
16969 behavior on 64-bit hosts with printf arg.
16970 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
16971 (x_stop_queuing_selection_requests): Likewise.
16972 (x_get_window_property): Don't truncate byte count to an 'int'
16975 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
16976 here, since it parses constructs like leading '-' and spaces,
16977 which are not wanted; and it overflows with large numbers.
16978 Instead, simply match F[0-9]+, which is what is wanted anyway.
16980 * alloc.c: Remove unportable assumptions about struct layout.
16981 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
16982 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
16983 (allocate_vectorlike, make_pure_vector): Use the new macros,
16984 plus offsetof, to remove unportable assumptions about struct layout.
16985 These assumptions hold on all porting targets that I know of, but
16986 they are not guaranteed, they're easy to remove, and removing them
16987 makes further changes easier.
16989 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
16990 This doesn't fix a bug but makes the code clearer.
16991 (string_overrun_cookie): Now const. Use initializers that
16992 don't formally overflow signed char, to avoid warnings.
16993 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
16994 can cause Emacs to crash when string overrun checking is enabled.
16995 (allocate_buffer): Don't assume sizeof (struct buffer) is a
16996 multiple of sizeof (EMACS_INT); it need not be, if
16997 alignof(EMACS_INT) < sizeof (EMACS_INT).
16998 (check_sblock, check_string_bytes, check_string_free_list): Protoize.

17034 supported by the function. Use SAFE_ALLOCA instead of always
17037 * eval.c (verror): Don't limit the buffer size at size_max-1, that
17038 is one byte too soon. Don't use xrealloc; instead xfree and

17050 docstring. Start callback support.
17051 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake

17156 codepoint of an invalid character, to avoid displaying a bogus
17159 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to

17165 * charset.c (check_iso_charset_parameter): Fix incorrect argument
17166 to `error' in error message about FINAL_CHAR argument. Make sure
17167 FINAL_CHAR is a character, and use %c when it is passed as
17168 argument to `error'.
17170 2011-04-23 Eli Zaretskii <eliz@gnu.org>
17172 * s/ms-w32.h (localtime): Redirect to sys_localtime.
17174 * w32.c: Include <time.h>.

17238 * dispextern.h (struct redisplay_interface): Rename param
17239 to avoid shadowing.
17240 * termhooks.h (struct terminal): Likewise.

17357 * nsfont.m: Fixed bugs in ns_get_family and
17358 ns_descriptor_to_entity that were caused by using free to
17359 deallocate memory blocks that were allocated by xmalloc (via
17360 xstrdup). This caused Emacs to crash when compiled with
17361 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
17362 --enable-checking=xmallocoverrun). xfree is now used to
17363 deallocate these memory blocks.
17365 2011-04-15 Paul Eggert <eggert@cs.ucla.edu>
17367 * sysdep.c (emacs_read): Remove unnecessary check vs MAX_RW_COUNT.

17377 (emacs_read, emacs_write): Remove check for negative size, as the
17378 Emacs source code has been audited now.
17379 * sysdep.c (MAX_RW_COUNT): New macro, to work around kernel bugs.
17380 (emacs_read, emacs_write): Use it.
17381 * process.c (send_process): Adjust to the new signatures of
17382 emacs_write and emacs_gnutls_write. Do not attempt to store
17383 a byte offset into an 'int'; it might overflow.
17384 See http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00483.html

17408 * font.c (Qopentype): Don't make static (used from w32uniscribe.c).
17410 2011-04-14 Paul Eggert <eggert@cs.ucla.edu>
17412 Improve C-level modularity by making more things 'static'.
17414 Don't publish debugger-only interfaces to other modules.

17826 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
17828 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
17831 2011-04-13 Eli Zaretskii <eliz@gnu.org>
17833 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
17834 when at ZV. (Bug#8487)
17836 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
17838 * charset.c (Fclear_charset_maps): Use xfree instead of free.
17840 * keyboard.c (parse_tool_bar_item): Likewise.
17841 * sound.c (sound_cleanup, alsa_close): Likewise.
17842 * termcap.c (tgetent): Likewise.
17843 * xfns.c (x_default_font_parameter): Likewise.
17844 * xsettings.c (read_and_apply_settings): Likewise.
17846 * alloc.c (overrun_check_malloc, overrun_check_realloc)
17847 (overrun_check_free): Protoize.
17849 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
17851 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
17852 since callers should never pass a negative size.
17853 Change the signature to match that of plain 'read' and 'write'; see
17854 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
17855 * lisp.h: Update prototypes of emacs_write and emacs_read.
17857 2011-04-11 Eli Zaretskii <eliz@gnu.org>
17859 * xdisp.c (redisplay_window): Don't try to determine the character
17860 position of the scroll margin if the window start point w->startp
17861 is outside the buffer's accessible region. (Bug#8468)
17863 2011-04-10 Eli Zaretskii <eliz@gnu.org>
17865 Fix write-region and its subroutines for buffers > 2GB.
17866 * fileio.c (a_write, e_write): Modify declaration of arguments and
17867 local variables to support buffers larger than 2GB.
17868 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
17870 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
17871 argument, local variables, and return value.
17873 * lisp.h: Update prototypes of emacs_write and emacs_read.
17875 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
17877 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
17879 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
17881 Fix more problems found by GCC 4.6.0's static checks.
17883 * xdisp.c (vmessage): Use a better test for character truncation.
17885 * charset.c (load_charset_map): <, not <=, for optimization,
17886 and to avoid potential problems with integer overflow.
17887 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
17888 * casetab.c (set_identity, shuffle): Likewise.
17889 * editfns.c (Fformat): Likewise.
17890 * syntax.c (skip_chars): Likewise.
17892 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
17893 This also lets GCC 4.6.0 generate slightly better loop code.
17895 * callint.c (Fcall_interactively): <, not <=, for optimization.
17896 (Fcall_interactively): Count the number of arguments produced,
17897 not the number of arguments given. This is simpler and lets GCC
17898 4.6.0 generate slightly better code.
17900 * ftfont.c: Distingish more carefully between FcChar8 and char.
17901 The previous code passed unsigned char * to a functions like
17902 strlen and xstrcasecmp that expect char *, which does not
17903 conform to the C standard.
17904 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
17905 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
17906 char * when the C standard requires it.
17908 * keyboard.c (read_char): Remove unused var.
17910 * eval.c: Port to Windows vsnprintf (Bug#8435).
17911 Include <limits.h>.
17912 (SIZE_MAX): Define if the headers do not.
17913 (verror): Do not give up if vsnprintf returns a negative count.
17914 Instead, grow the buffer. This ports to Windows vsnprintf, which
17915 does not conform to C99. Problem reported by Eli Zaretskii.
17916 Also, simplify the allocation scheme, by avoiding the need for
17917 calling realloc, and removing the ALLOCATED variable.
17919 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
17921 Remove invocations of doprnt, as Emacs now uses vsnprintf.
17922 But keep the doprint source code for now, as we might revamp it
17923 and use it again (Bug#8435).
17924 * lisp.h (doprnt): Remove.
17925 * Makefile.in (base_obj): Remove doprnt.o.
17926 * deps.mk (doprnt.o): Remove.
17928 error: Print 32- and 64-bit integers portably (Bug#8435).
17929 Without this change, on typical 64-bit hosts error ("...%d...", N)
17930 was used to print both 32- and 64-bit integers N, which relied on
17931 undefined behavior.
17932 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
17933 * lisp.h (error, verror): Mark as printf-like functions.
17934 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
17935 Report overflow in size calculations when allocating printf buffer.
17936 Do not truncate output string at its first null byte.
17937 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
17938 Truncate the output at a character boundary, since vsnprintf does not
17940 * charset.c (check_iso_charset_parameter): Convert internal
17941 character to string before calling 'error', since %c now has the
17943 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
17944 overflow when computing char to be passed to 'error'. Do not
17945 pass Lisp_Object to 'error'; pass the integer instead.
17946 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
17947 formatted with plain %d.
17949 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
17951 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
17953 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
17955 * xterm.c (x_catch_errors): Remove duplicate declaration.
17957 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
17959 * xdisp.c, lisp.h (message_nolog): Remove; unused.
17961 2011-04-10 Jim Meyering <meyering@redhat.com>
17963 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
17964 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
17965 return ssize_t not "int", and use size_t as the buffer length.
17966 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
17967 * gnutls.h: Update declarations.
17968 * process.c (read_process_output): Use ssize_t, to match.
17969 (send_process): Likewise.
17971 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
17973 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
17975 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
17977 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
17978 Use unsigned char, to match FcChar8 type definition.
17980 * xterm.c (handle_one_xevent):
17981 * xmenu.c (create_and_show_popup_menu):
17982 * xselect.c (x_decline_selection_request)
17983 (x_reply_selection_request): Avoid type-punned deref of X events.
17985 2011-04-09 Eli Zaretskii <eliz@gnu.org>
17987 Fix some uses of `int' instead of EMACS_INT.
17988 * search.c (string_match_1, fast_string_match)
17989 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
17990 (scan_buffer, find_next_newline_no_quit)
17991 (find_before_next_newline, search_command, Freplace_match)
17992 (Fmatch_data): Make some `int' variables be EMACS_INT.
17994 * xdisp.c (display_count_lines): 3rd argument and return value now
17995 EMACS_INT. All callers changed.
17996 (pint2hrstr): Last argument is now EMACS_INT.
17998 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
17999 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
18000 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
18001 (decode_coding_utf_16, decode_coding_emacs_mule)
18002 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
18003 (decode_coding_ccl, decode_coding_charset)
18004 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
18005 (decode_coding_iso_2022, decode_coding_emacs_mule)
18006 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
18007 <char_offset, last_offset>: Declare EMACS_INT.
18008 (encode_coding_utf_8, encode_coding_utf_16)
18009 (encode_coding_emacs_mule, encode_invocation_designation)
18010 (encode_designation_at_bol, encode_coding_iso_2022)
18011 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
18012 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
18014 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
18015 (encode_invocation_designation): Last argument P_NCHARS is now
18017 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
18018 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
18020 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
18023 * ccl.c (Fccl_execute_on_string): Declare some variables
18026 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
18028 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
18030 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
18032 * process.c (Fformat_network_address): Doc fix.
18034 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
18036 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
18038 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
18040 * keyboard.c (read_char): Call Lisp function help-form-show,
18041 instead of using internal_with_output_to_temp_buffer.
18042 (Qhelp_form_show): New var.
18043 (syms_of_keyboard): Use DEFSYM macro.
18045 * print.c (internal_with_output_to_temp_buffer): Function deleted.
18047 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
18049 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
18051 * process.c (Flist_processes): Remove to Lisp.
18052 (list_processes_1): Delete.
18054 2011-04-06 Eli Zaretskii <eliz@gnu.org>
18056 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
18058 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
18060 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
18062 Fix more problems found by GCC 4.6.0's static checks.
18064 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
18066 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
18068 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
18070 * xdisp.c (vmessage): Mark as a printf-like function.
18072 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
18074 * sound.c (sound_warning): Don't crash if arg contains a printf format.
18076 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
18077 printf-like functions.
18078 (tiff_load): Add casts to remove these marks before passing them
18079 to system-supplied API.
18081 * eval.c (Fsignal): Remove excess argument to 'fatal'.
18083 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
18084 This avoids several warnings with gcc -Wstrict-overflow.
18085 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
18086 directly, rather than having caller test rule sign. This avoids
18087 some unnecessary tests.
18088 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
18089 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
18090 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
18092 * xfont.c (xfont_text_extents): Remove var that was set but not used.
18093 (xfont_open): Avoid unnecessary tests.
18095 * composite.c (composition_gstring_put_cache): Use unsigned integer.
18097 * composite.h, composite.c (composition_gstring_put_cache):
18098 Use EMACS_INT, not int, for length.

18101 breaking out part of COMPOSITION_DECODE_RULE.
18102 (COMPOSITION_DECODE_RULE): Use it.
18103 * composite.c (get_composition_id): Remove unused local vars,
18104 by using the new macro.
18106 * textprop.c (set_text_properties_1): Change while to do-while,
18107 since the condition is always true at first.
18109 * intervals.c (graft_intervals_into_buffer): Mark var as used.
18110 (interval_deletion_adjustment): Return unsigned value.
18113 * process.c (list_processes_1, create_pty, read_process_output):

18123 (update_syntax_table): Use unsigned instead of int.
18125 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
18126 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
18127 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
18129 * print.c (print_error_message): Avoid int overflow.
18131 * font.c (font_list_entities): Redo for clarity,
18132 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
18134 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
18135 (font_score): Avoid potential overflow in diff calculation.
18137 * fns.c (substring_both): Remove var that is set but not used.
18138 (sxhash): Redo loop for clarity and to avoid wraparound warning.
18140 * eval.c (funcall_lambda): Rename local to avoid shadowing.
18142 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
18143 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
18144 can always succeed if overflow has undefined behavior.
18146 * search.c (boyer_moore, wordify): Remove vars set but not used.
18147 (wordify): Omit three unnecessary tests.
18149 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
18150 All callers changed. This avoids the need for an unused var.
18152 * casefiddle.c (casify_region): Remove var that is set but not used.
18154 * dired.c (file_name_completion): Remove var that is set but not used.
18156 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
18158 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
18159 (Finsert_file_contents): Remove unnecessary code checking fd.
18161 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
18162 Check for integer overflow on size calculations.
18164 * buffer.c (Fprevious_overlay_change): Remove var that is set
18167 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
18168 Remove vars that are set but not used.
18169 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
18170 (timer_check_2): Mark vars as initialized.
18172 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
18174 * image.c (lookup_image): Remove var that is set but not used.
18175 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
18177 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
18178 that are set but not used.
18180 * xfns.c (make_invisible_cursor): Don't return garbage
18181 if XCreateBitmapFromData fails (Bug#8410).
18183 * xselect.c (x_get_local_selection, x_handle_property_notify):
18184 Remove vars that are set but not used.
18186 * xfns.c (x_create_tip_frame): Remove var that is set but not used.

18196 (map_tty_color) [!defined MSDOS]: Likewise.
18198 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
18200 * coding.c: Remove vars that are set but not used.
18201 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
18202 All callers changed.
18203 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
18204 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
18205 (decode_coding_charset): Remove vars that are set but not used.
18207 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
18208 that is set but not used.
18210 * print.c (print_object): Remove var that is set but not used.
18212 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
18213 The gnulib version avoids calling malloc in the usual case,
18214 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
18215 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
18216 * filelock.c (current_lock_owner): Likewise.
18217 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
18218 * sysdep.c: Include allocator.h, careadlinkat.h.
18219 (emacs_no_realloc_allocator): New static constant.
18220 (emacs_readlink): New function.
18221 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
18222 ../lib/careadlinkat.h.
18224 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
18226 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
18227 first non-nil return value).
18229 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
18231 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
18232 if not defined (Bug#8403).
18234 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
18236 * xdisp.c (display_count_lines): Remove parameter `start',
18237 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
18238 (get_char_face_and_encoding): Remove parameter `multibyte_p',
18239 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

18241 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
18242 and thereabouts. All callers changed.
18243 (get_per_char_metric): Remove parameter `f', unused since
18244 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
18246 2011-04-02 Jim Meyering <meyering@redhat.com>
18248 do not dereference NULL upon failed strdup
18249 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
18250 (ns_get_family): Likewise.
18252 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
18254 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
18256 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
18258 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or

18276 (syms_of_lread): Declare `lexical-binding'.
18278 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
18280 * keyboard.c (eval_dyn): New fun.
18281 (menu_item_eval_property): Use it.
18283 * image.c (parse_image_spec): Use Ffunctionp.
18285 * fns.c (concat, mapcar1): Accept byte-code-functions.
18287 * eval.c (Fsetq): Handle lexical vars.
18288 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
18289 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
18290 (FletX, Flet): Obey lexical binding.
18291 (Fcommandp): Handle closures.
18292 (Feval): New `lexical' arg.
18293 (eval_sub): New function extracted from Feval. Use it almost
18294 everywhere where Feval was used. Look up vars in lexical env.
18296 (Ffunctionp): Move from subr.el.
18297 (Ffuncall): Handle closures.
18298 (apply_lambda): Remove `eval_flags'.
18299 (funcall_lambda): Handle closures and new byte-code-functions.
18300 (Fspecial_variable_p): New function.
18301 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
18302 but without exporting it to Lisp.
18304 * doc.c (Fdocumentation, store_function_docstring):
18305 * data.c (Finteractive_form): Handle closures.
18307 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
18310 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
18312 (exec_byte_code): New function extracted from Fbyte_code to handle new
18313 calling convention for byte-code-functions. Add new byte-codes.
18315 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
18317 * alloc.c (Fmake_symbol): Init new `declared_special' field.
18319 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
18321 * xdisp.c (redisplay_internal): Fix prototype.
18323 2011-03-31 Eli Zaretskii <eliz@gnu.org>
18325 * xdisp.c (SCROLL_LIMIT): New macro.
18326 (try_scrolling): Use it when setting scroll_limit.
18327 Limit scrolling to 100 screen lines.
18328 (redisplay_window): Even when falling back on "recentering",
18329 position point in the window according to scroll-conservatively,
18330 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
18332 (try_scrolling): When point is above the window, allow searching
18333 as far as scroll_max, or one screenful, to compute vertical
18334 distance from PT to the scroll margin position. This prevents
18335 try_scrolling from unnecessarily failing when
18336 scroll-conservatively is set to a value slightly larger than the
18337 window height. Clean up the case of PT below the margin at bottom
18338 of window: scroll_max can no longer be INT_MAX. When aggressive
18339 scrolling is in use, don't let point enter the opposite scroll
18340 margin as result of the scroll.
18341 (syms_of_xdisp) <scroll-conservatively>: Document the
18342 threshold of 100 lines for never-recentering scrolling.
18344 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
18346 * dispextern.h (move_it_by_lines):
18347 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
18348 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
18349 (message_log_check_duplicate): Remove parameters `prev_bol' and
18350 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
18351 (redisplay_internal): Remove parameter `preserve_echo_area',
18352 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
18354 * indent.c (Fvertical_motion):
18355 * window.c (window_scroll_pixel_based, Frecenter):
18356 Don't pass `need_y_p' to `move_it_by_lines'.
18358 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
18360 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
18361 steal a few bits to be more compact.
18362 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
18363 Remove unneeded casts.
18365 * bytecode.c (Fbyte_code): CAR and CDR can GC.
18367 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
18369 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
18370 binding" message (bug#7967).
18372 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
18374 Fix more problems found by GCC 4.6.0's static checks.
18376 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
18377 Remove unused local var.
18379 * editfns.c (Fmessage_box): Remove unused local var.
18381 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
18382 (note_mode_line_or_margin_highlight, note_mouse_highlight):
18383 Omit unused local vars.
18384 * window.c (shrink_windows): Omit unused local var.
18385 * menu.c (digest_single_submenu): Omit unused local var.
18386 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
18387 Omit unused local var.
18389 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
18390 Don't assume string length fits in int.
18391 (keyremap_step, read_key_sequence): Use size_t for sizes.
18392 (read_key_sequence): Don't check last_real_key_start redundantly.
18394 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
18395 instead of alloca (Bug#8344).
18397 * eval.c (Fbacktrace): Don't assume nargs fits in int.
18398 (Fbacktrace_frame): Don't assume nframes fits in int.
18400 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
18402 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
18405 * term.c (produce_glyphless_glyph): Remove unnecessary test.
18407 * cm.c (calccost): Turn while-do into do-while, for clarity.
18409 * keyboard.c (syms_of_keyboard): Use the same style as later
18410 in this function when indexing through an array. This also
18411 works around GCC bug 48267.
18413 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
18415 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
18417 * chartab.c (sub_char_table_ref_and_range): Redo for slight
18418 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
18420 * keyboard.c, keyboard.h (num_input_events): Now size_t.
18421 This avoids undefined behavior on integer overflow, and is a bit
18422 more convenient anyway since it is compared to a size_t variable.
18424 Variadic C functions now count arguments with size_t, not int.
18425 This avoids an unnecessary limitation on 64-bit machines, which
18426 caused (substring ...) to crash on large vectors (Bug#8344).
18427 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
18428 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
18429 All variadic functions and their callers changed accordingly.
18430 (struct gcpro.nvars): Now size_t, not int. All uses changed.
18431 * data.c (arith_driver, float_arith_driver): Likewise.
18432 * editfns.c (general_insert_function): Likewise.
18433 * eval.c (struct backtrace.nargs, interactive_p)
18434 (internal_condition_case_n, run_hook_with_args, apply_lambda)
18435 (funcall_lambda, mark_backtrace): Likewise.
18436 * fns.c (concat): Likewise.
18437 * frame.c (x_set_frame_parameters): Likewise.
18438 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
18439 0 if not found, not -1. All callers changed.
18441 * alloc.c (garbage_collect): Don't assume stack size fits in int.
18442 (stack_copy_size): Now size_t, not int.
18443 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
18445 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
18447 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
18448 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
18449 All callers changed.
18451 * lisp.h (multibyte_char_to_unibyte):
18452 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
18453 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
18454 * character.h (CHAR_TO_BYTE8):
18455 * cmds.c (internal_self_insert):
18456 * editfns.c (general_insert_function):
18457 * keymap.c (push_key_description):
18458 * search.c (Freplace_match):
18459 * xdisp.c (message_dolog, set_message_1): All callers changed.
18461 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
18463 * keyboard.c (safe_run_hook_funcall): New function.
18464 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
18465 don't set the hook to nil, but remove the offending function instead.
18466 (Qcommand_hook_internal): Remove, unused.
18467 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
18468 Vcommand_hook_internal.
18470 * eval.c (enum run_hooks_condition): Remove.
18471 (funcall_nil, funcall_not): New functions.
18472 (run_hook_with_args): Call each function through a `funcall' argument.
18473 Remove `cond' argument, now redundant.
18474 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
18475 (Frun_hook_with_args_until_failure): Adjust accordingly.
18476 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
18478 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
18480 * dispextern.h (string_buffer_position): Remove declaration.
18482 * print.c (strout): Remove parameter `multibyte', unused since
18483 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
18485 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
18486 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
18487 All callers changed.
18489 * w32.c (_wsa_errlist): Use braces for struct initializers.
18491 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
18492 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
18493 All callers changed.
18494 (string_buffer_position): Likewise. Also, make static (it's never
18495 used outside xdisp.c).
18496 (cursor_row_p): Remove parameter `w', unused since
18497 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.

18499 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
18500 All callers changed.
18502 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
18504 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.
18506 2011-03-27 Anders Lindgren <andlind@gmail.com>
18508 * nsterm.m (ns_menu_bar_is_hidden): New variable.
18509 (ns_constrain_all_frames, ns_menu_bar_should_be_hidden)
18510 (ns_update_auto_hide_menu_bar): New functions.
18511 (ns_update_begin): Call ns_update_auto_hide_menu_bar.

18515 (syms_of_nsterm): DEFVAR ns-auto-hide-menu-bar, init to Qnil.
18517 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
18519 * nsmenu.m (runDialogAt): Remove argument to timer_check.
18521 2011-03-27 Glenn Morris <rgm@gnu.org>
18523 * syssignal.h: Replace RETSIGTYPE with void.
18524 * atimer.c, data.c, dispnew.c, emacs.c, floatfns.c, keyboard.c:
18525 * keyboard.h, lisp.h, process.c, sysdep.c, xterm.c:
18526 Replace SIGTYPE with void everywhere.
18527 * s/usg5-4-common.h (SIGTYPE): Remove definition.
18528 * s/template.h (SIGTYPE): Remove commented out definition.
18530 2011-03-26 Eli Zaretskii <eliz@gnu.org>
18532 * xdisp.c (redisplay_window): Don't check buffer's clip_changed
18533 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
18535 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
18537 * w32.c (read_unc_volume): Use parameter `henum', instead of
18538 global variable `wget_enum_handle'.
18540 * keymap.c (describe_vector): Remove parameters `indices' and
18541 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.
18542 (describe_map, Fdescribe_vector): Adjust calls to `describe_vector'.
18544 * keyboard.h (timer_check, show_help_echo): Remove unused parameters.
18546 * keyboard.c (timer_check): Remove parameter `do_it_now',
18547 unused since 1996-04-12T06:01:29Z!rms@gnu.org.
18548 (show_help_echo): Remove parameter `ok_to_overwrite_keystroke_echo',
18549 unused since 2008-04-19T19:30:53Z!monnier@iro.umontreal.ca.
18551 * keyboard.c (read_char):
18552 * w32menu.c (w32_menu_display_help):
18553 * xmenu.c (show_help_event, menu_help_callback):
18554 Adjust calls to `show_help_echo'.
18556 * gtkutil.c (xg_maybe_add_timer):
18557 * keyboard.c (readable_events):
18558 * process.c (wait_reading_process_output):
18559 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
18561 * insdel.c (adjust_markers_gap_motion):
18562 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.
18563 (gap_left, gap_right): Don't call it.
18565 2011-03-25 Chong Yidong <cyd@stupidchicken.com>
18567 * xdisp.c (handle_fontified_prop): Discard changes to clip_changed
18568 incurred during fontification.

18609 2011-03-24 Juanma Barranquero <lekktu@gmail.com>
18611 * w32term.c (x_set_glyph_string_clipping):
18612 Don't pass uninitialized region to CombineRgn.
18614 2011-03-23 Juanma Barranquero <lekktu@gmail.com>
18616 * w32fns.c (x_set_menu_bar_lines): Remove unused variable `olines'.
18617 (w32_wnd_proc): Pass NULL to Windows API, not uninitialized buffer.
18618 (Fx_close_connection): Remove unused variable `i'.
18620 * w32font.c (w32font_draw): Return number of glyphs.
18621 (w32font_open_internal): Remove unused variable `i'.

18634 (uniscribe_font_driver): Add missing initializers.
18636 2011-03-23 Julien Danjou <julien@danjou.info>
18638 * term.c (Fsuspend_tty, Fresume_tty):
18639 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
18640 * window.c (temp_output_buffer_show):
18641 * insdel.c (signal_before_change):
18642 * frame.c (Fhandle_switch_frame):
18643 * fileio.c (Fdo_auto_save):
18644 * emacs.c (Fkill_emacs):
18645 * editfns.c (save_excursion_restore):
18646 * cmds.c (internal_self_insert):
18647 * callint.c (Fcall_interactively):
18648 * buffer.c (Fkill_all_local_variables):
18649 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
18651 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
18652 unconditionally since it does the check itself.
18654 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
18656 Fix more problems found by GCC 4.5.2's static checks.
18658 * coding.c (encode_coding_raw_text): Avoid unnecessary test
18659 the first time through the loop, since we know p0 < p1 then.
18660 This also avoids a gcc -Wstrict-overflow warning.
18662 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
18663 leading to a memory leak, possible in functions like
18664 load_charset_map_from_file that can allocate an unbounded number
18665 of objects (Bug#8318).
18667 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
18668 that could (at least in theory) be that large.
18670 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
18671 This is less likely to overflow, and avoids undefined behavior if
18672 overflow does occur. All callers changed. Use strtoul to scan
18673 for the unsigned long integer.
18674 (pint2hrstr): Simplify and tune code slightly.
18675 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
18677 * scroll.c (do_scrolling): Work around GCC bug 48228.
18678 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
18680 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
18681 This also avoids a warning with gcc -Wstrict-overflow.
18682 (validate_x_resource_name): Simplify count usage.
18683 This also avoids a warning with gcc -Wstrict-overflow.
18685 * fileio.c (Fcopy_file): Report error if fchown or fchmod
18688 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
18690 * process.c (Fmake_network_process): Use socklen_t, not int,
18691 where POSIX says socklen_t is required in portable programs.
18692 This fixes a porting bug on hosts like 64-bit HP-UX, where
18693 socklen_t is wider than int (Bug#8277).
18694 (Fmake_network_process, server_accept_connection):
18695 (wait_reading_process_output, read_process_output):
18698 * process.c: Rename or move locals to avoid shadowing.
18699 (list_processes_1, Fmake_network_process):
18700 (read_process_output_error_handler, exec_sentinel_error_handler):
18701 Rename or move locals.
18702 (Fmake_network_process): Define label "retry_connect" only if needed.
18703 (Fnetwork_interface_info): Fix pointer signedness.
18704 (process_send_signal): Add cast to avoid pointer signedness problem.
18705 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
18706 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
18708 Make tparam.h and terminfo.c consistent.
18709 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
18710 Include tparam.h instead, since it declares them.
18711 * cm.h (PC): Remove extern decl; tparam.h now does this.

18770 clobbering (Bug#8298).
18771 * sysdep.c (sys_subshell): Likewise.
18772 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
18774 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
18775 This should get cleaned up, so that child_setup has the
18776 same signature on all platforms.
18778 * callproc.c (call_process_cleanup): Now static.
18779 (relocate_fd): Rename locals to avoid shadowing.
18781 2011-03-22 Chong Yidong <cyd@stupidchicken.com>

18940 (Fmemory_limit): Cast sbrk's returned value to char *.
18942 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this

18950 to use the following functions instead of these macros.
18951 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
18952 EMACS_INT, since callers assume the returned value fits in int.
18953 (upcase1): Likewise, for UPCASE_TABLE.
18954 (uppercasep, lowercasep, upcase): New static inline functions.
18955 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

18965 (regex_compile, re_match_2_internal): Mark locals as initialized.
18966 (RETALLOC_IF): Define only if needed.
18967 (WORDCHAR_P): Likewise. This one is never needed, but is used
18968 only in a comment talking about a compiler bug, so put inside
18969 the #if 0 of that comment.
18970 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
18971 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

18998 New macros, so that the caller can use some names other than
18999 gcpro1, gcpro2, etc.
19000 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
19002 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
19003 argument, for consistency with GCPRO2_VAR, etc: it is now the
19004 prefix of the variable, not the variable itself. All uses
19006 * dired.c (directory_files_internal, file_name_completion):
19007 Rename locals to avoid shadowing.
19009 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
19010 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
19011 dired.c's scmp function, had undefined behavior.
19012 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
19013 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
19014 * buffer.h: ... to here, because these macros use current_buffer,
19015 and the new implementation with inline functions needs to have
19016 current_buffer in scope now, rather than later when the macros
19018 (downcase, upcase1): New static inline functions.
19019 (DOWNCASE, UPCASE1): Reimplement using these functions.
19020 This avoids undefined behavior in expressions like
19021 DOWNCASE (x) == DOWNCASE (y), which previously suffered
19022 from race conditions in accessing the global variables
19023 case_temp1 and case_temp2.
19024 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
19025 * lisp.h (case_temp1, case_temp2): Remove their decls.
19026 * character.h (ASCII_CHAR_P): Move from here ...

19035 (file_name_as_directory): Use const pointers when appropriate.

19039 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
19041 (Fset_file_times, Finsert_file_contents, auto_save_error):

19048 * marker.c (bytepos_to_charpos): Remove; unused.
19050 * lisp.h (verify_bytepos, count_markers): New decls,
19051 so that gcc does not warn that these functions aren't declared.

19054 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.

19061 * buffer.c (fix_overlays_before): Mark locals as initialized.
19062 (fix_start_end_in_overlays): Likewise. This function should be
19063 simplified by using pointers-to-pointers, but that's a different

19066 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
19067 (report_overlay_modification): Rename locals to avoid shadowing.

19072 to suppress a gcc -Wclobbered warning that does not seem to be right.
19073 (MAXPATHLEN): Define only if needed.
19075 * process.c (serial_open, serial_configure): Move decls from here ...
19076 * systty.h: ... to here, so that they can be checked.
19078 * fns.c (get_random, seed_random): Move extern decls from here ...
