12 Revert recent change for Bug#8855.
13 As reported by Harald Hanche-Olsen in
14 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00445.html>
15 the change introduces a further bug, of creating lots of zombie
16 processes in some cases. Further work is needed to come up with a
17 better fix for Bug#8855.
19 2012-11-24 Eli Zaretskii <eliz@gnu.org>
21 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
22 highlighting on the frame was cleared. Prevents assertion
23 violations when repeatedly clicking on the "Top" link of the
24 "bread-crumbs" in Info buffers.
26 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>

29 Fix a race condition with glib (Bug#8855).
30 The symptom is a diagnostic "GLib-WARNING **: In call to
31 g_spawn_sync(), exit status of a child process was requested but
32 SIGCHLD action was set to SIG_IGN and ECHILD was received by
33 waitpid(), so exit status can't be returned." The diagnostic
34 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
35 The real bug is a race condition between Emacs and glib: Emacs
36 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
37 so that glib can't find it. Work around the bug by invoking
38 waitpid only on subprocesses that Emacs itself creates.
40 This is a backport from the trunk, consisting of:
42 * w32proc.c (create_child): Don't clip the PID of the child
43 process to fit into an Emacs integer, as this is no longer a
45 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
46 reaping only the process specified by PID argument, if that is
47 positive. Use PID instead of dead_child to know which process to
48 reap. Wait for the child to die only if WNOHANG is not in
50 (sys_select): Don't set dead_child.
52 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
53 as it is no longer needed.
55 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
57 (create_process, record_child_status_change): Don't use special
58 value -1 in pid field, as the caller now must know the pid rather
59 than having the callee infer it. The inference was sometimes
60 incorrect anyway, due to another race.
61 (create_process): Set new 'alive' member if child is created.
62 (process_status_retrieved): New function.
63 (record_child_status_change): Use it.
64 Accept negative 1st argument, which means to wait for the
65 processes that Emacs already knows about. Move special-case code
66 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
67 processes that have already been waited for, by testing and
68 clearing new 'alive' member. Remove the setting of
69 record_at_most_one_child for the !WNOHANG case.
70 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
71 now does this internally.
72 (handle_child_signal): Let record_child_status_change do all
73 the work, since we do not want to reap all exited child processes,
74 only the child processes that Emacs itself created.
75 * process.h (Lisp_Process): New boolean member 'alive'.
77 2012-11-23 Eli Zaretskii <eliz@gnu.org>
79 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
80 between bpos_covered and bpos_max. This fixes cursor display when
81 several display strings follow each other.
83 * .gdbinit (pgx): If the glyph's object is a string, display the
84 pointer to string data, rather than the value of the string object
85 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
87 2012-11-21 Eli Zaretskii <eliz@gnu.org>
89 * indent.c (Fvertical_motion): If the starting position is covered
90 by a display string, return to one position before that, to avoid
91 overshooting it inside move_it_to. (Bug#12930)
93 2012-11-20 Daniel Colascione <dancol@dancol.org>
95 * w32fns.c (Fx_file_dialog):
96 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
97 cygwin_convert_file_name*.
99 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
100 Rename cygwin_convert_path* to cygwin_convert_file_name*.
102 2012-11-20 Ken Brown <kbrown@cornell.edu>
104 * emacs.c (main): Set the G_SLICE environment variable for all
105 Cygwin builds, not just GTK builds. See
106 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
108 2012-11-19 Eli Zaretskii <eliz@gnu.org>
110 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Don't mix declaration of
111 w32_note_current_window with code. (Backport from trunk.)
113 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
114 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
115 Define for the MSVC compiler.
117 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing
120 2012-11-18 Eli Zaretskii <eliz@gnu.org>
122 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
123 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
124 dostounix_filename. Prevents crashes down the road, because
125 dostounix_filename assumes it gets a unibyte string. Reported by
126 Michel de Ruiter <michel@sentient.nl>, see
127 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html
129 2012-11-17 Eli Zaretskii <eliz@gnu.org>
131 * w32select.c: Include w32common.h before w32term.h, so that
132 windows.h gets included before w32term.h uses some of its
135 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]: New
137 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]: New
139 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
141 2012-11-17 Jan Djärv <jan.h.d@swipnet.se>
143 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
144 (ns_select): Return at once if events are held (Bug#12834).
146 2012-11-16 enami tsugutomo <tsugutomo.enami@jp.sony.com>
148 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
149 Needed following 2012-10-20 change. (Bug#12902)
151 2012-11-16 Glenn Morris <rgm@gnu.org>
153 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
155 2012-11-15 Stefan Monnier <monnier@iro.umontreal.ca>
157 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
159 2012-11-14 Eli Zaretskii <eliz@gnu.org>
161 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
162 use the same value of thread handle.
163 (start_timer_thread): If the timer thread exited (due to error),
164 clean up by closing the two handles it used. Duplicate the caller
165 thread's handle here, so it gets duplicated only once, when
166 launching the timer thread. Set priority of the timer thread, not
168 (getitimer): Don't duplicate the caller thread's handle here.
171 2012-11-13 Jan Djärv <jan.h.d@swipnet.se>
173 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
176 2012-11-12 Eli Zaretskii <eliz@gnu.org>
178 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
179 passed to pint2str and pint2hrstr to be at most the size of the
180 frame's decode_mode_spec_buffer. This avoids crashes with very
181 large values of FIELD_WIDTH argument to decode_mode_spec.
184 2012-11-07 Martin Rudalics <rudalics@gmx.at>
186 * window.c (Fsplit_window_internal): Set combination limit of
187 new parent window to t iff Vwindow_combination_limit is t;
188 fixing a regression introduced with the change from 2012-09-22.
189 (Fwindow_combination_limit, Fset_window_combination_limit):
192 2012-11-06 Eli Zaretskii <eliz@gnu.org>
194 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
195 amount when the scroll margins are too large. When scrolling
196 backwards in the buffer, give up if cannot reach point or the
197 scroll margin within a reasonable number of screen lines.
198 Fixes point position in window under scroll-up/down-aggressively when
199 point is positioned many lines beyond the window top/bottom.
202 2012-11-05 Eli Zaretskii <eliz@gnu.org>
204 * ralloc.c (relinquish): If real_morecore fails to return memory
205 to the system, don't crash; instead, leave the last heap
206 unchanged and return. (Bug#12774)
208 2012-11-03 Eli Zaretskii <eliz@gnu.org>
210 * lisp.mk: Adjust comments to the fact that term/internal is now
211 loaded from loadup.el.
213 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
214 (msdos_fatal_signal): New function.
215 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
218 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
219 for GCC versions before 4.
220 (emacs_raise): Define to call msdos_fatal_signal.
222 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
223 iterator when starting in the middle of a display or overlay
226 2012-11-03 Jan Djärv <jan.h.d@swipnet.se>
228 * widget.c (resize_cb): New function.
229 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
230 (EmacsFrameResize): Check if all is up to date before changing frame
233 2012-11-01 Eli Zaretskii <eliz@gnu.org>
235 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
237 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
239 Fix crash when using Emacs as commit editor for git (Bug#12697).
240 * callproc.c (setpgrp): Remove macro, as we now use setpgid
241 and it is configured in conf_post.h.
242 (Fcall_process): Don't invoke both setsid and setpgid; the former
243 is enough, if it exists.
244 * callproc.c (Fcall_process, child_setup):
245 * process.c (create_process): Use setpgid.
246 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
248 * dispnew.c (init_display): Initialize the foreground group
249 if we are running a tty display.
250 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
251 * lisp.h (init_foreground_group): New decl.
252 * sysdep.c (inherited_pgroup): New static var.
253 (init_foreground_group, tcsetpgrp_without_stopping)
254 (narrow_foreground_group, widen_foreground_group): New functions.
255 (init_sys_modes): Narrow foreground group.
256 (reset_sys_modes): Widen foreground group.
258 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
260 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
262 2012-10-31 Martin Rudalics <rudalics@gmx.at>
264 * minibuf.c (read_minibuf): Restore current buffer since
265 choose_minibuf_frame calling Fset_frame_selected_window may
266 change it (Bug#12766).
268 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
270 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
272 2012-10-30 Kenichi Handa <handa@gnu.org>
274 * font.c (Ffont_at): If WINDOW is specified and it is not
275 displaying the current buffer, signal an error.
277 2012-10-29 Daniel Colascione <dancol@dancol.org>
279 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
280 In preparation for fixing bug#12739, move these functions from
283 * coding.h, coding.c: ... to here, and compile them only when
284 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
285 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
287 2012-10-28 Eli Zaretskii <eliz@gnu.org>
289 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
290 (timer_loop, getitimer, setitimer): Use it instead of
291 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
293 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
296 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
298 * nsterm.m (NO_APPDEFINED_DATA): New define.
299 (last_appdefined_event_data): New variable
300 (last_appdefined_event): Remove.
301 (ns_select): Initialize t from last_appdefined_event_data instead
302 of [last_appdefined_event data1].
303 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
304 remove last_appdefined_event (Bug#12698).
306 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
308 * frame.c (x_set_font): Catch internal error.
310 2012-10-27 Eli Zaretskii <eliz@gnu.org>
312 Avoid overflow in w32 implementation of interval timers.
313 When possible, for ITIMER_PROF count only times the main thread
315 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
316 'volatile ULONGLONG' types. All the other data which was
317 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
318 (GetThreadTimes_Proc): New typedef.
319 (w32_get_timer_time): New function, returns a suitable time value
321 (timer_loop): Enter critical section when accessing ULONGLONG
322 values of the itimer_data struct, as these accesses are no longer
323 atomic. Call 'w32_get_timer_time' instead of 'clock'.
324 Remove unused variable.
325 (init_timers): Initialize s_pfn_Get_Thread_Times.
326 (start_timer_thread): Don't assign itimer->caller_thread here.
327 (getitimer): Assign itimer->caller_thread here.
328 (setitimer): Always call getitimer to get the value of ticks_now.
329 (sys_spawnve): Avoid compiler warning about format mismatch.
331 2012-10-26 Eli Zaretskii <eliz@gnu.org>
333 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
334 mouse movement events if the menu bar is active. This avoids
335 producing a busy "hour-glass" cursor by Windows if the mouse
336 pointer is positioned over a tooltip shown for some menu item.
338 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
340 Don't assume process IDs fit in int.
341 * emacs.c (shut_down_emacs) [!DOS_NT]:
342 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
343 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
344 Use pid_t, not int, to store process IDs, as 'int'
345 is not wide enough on a few platforms (e.g., AIX and IRIX).
347 2012-10-23 Kenichi Handa <handa@gnu.org>
349 The following change is to make face-font-rescale-alist work
350 correctly for non-ASCII fonts.
352 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
353 (font_open_for_lface): Handle Vface_font_rescale_alist.
355 2012-10-23 Chong Yidong <cyd@gnu.org>
357 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
359 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>
361 * nsfont.m (nsfont_open, ns_glyph_metrics): Force integer advancement
363 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
365 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
368 2012-10-21 Glenn Morris <rgm@gnu.org>
370 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
372 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
375 * frame.c (Fmouse_position, Fmouse_pixel_position):
376 * xdisp.c (produce_stretch_glyph):
377 Declare local vars only when they're needed.
378 This is clearer and avoids a warning on OpenBSD about unused vars.
379 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
380 This is safer, and avoids OpenBSD warnings about unused vars.
381 * keyboard.c (record_menu_key): Remove unnecessary decl.
382 (poll_timer): Define only if POLL_FOR_INPUT is defined.
383 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
384 as our definition clashes with OpenBSD's.
385 * xfaces.c (load_face_colors, check_lface_attrs)
386 (get_lface_attributes_no_remap, get_lface_attributes)
387 (lface_fully_specified_p, x_supports_face_attributes_p)
388 (tty_supports_face_attributes_p, face_fontset, realize_face)
389 (realize_x_face, realize_tty_face):
390 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
391 merely Lisp_Object *. This is more informative and avoids
392 a warning on OpenBSD about accessing beyond an object's size.
394 2012-10-20 Chong Yidong <cyd@gnu.org>
396 * lread.c (Fload): Doc fix (Bug#12592).
398 2012-10-19 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny change)
400 * font.c (Ffont_at): Fix previous change.
402 2012-10-19 Eli Zaretskii <eliz@gnu.org>
404 * puresize.h (BASE_PURESIZE): Bump the base value to 1700000.
405 See http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00593.html
408 * alloc.c (NSTATICS): Decrease to 0x800.
410 2012-10-19 Stefan Monnier <monnier@iro.umontreal.ca>
412 * fns.c (Fnreverse): Include the problem element when signalling an
415 2012-10-18 Jan Djärv <jan.h.d@swipnet.se>
417 * nsterm.m (ns_select): Check writefds before call to
418 FD_ISSET (Bug#12668).
420 2012-10-18 Daniel Colascione <dancol@dancol.org>
422 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
423 (staticpro): If we run out of staticpro slots, die with an
424 informative error instead of just calling emacs_abort.
426 2012-10-18 Martin Rudalics <rudalics@gmx.at>
428 Fix two flaws reported by Dmitry Antipov.
429 * window.c (Ftemp_output_buffer_show): Remove.

431 (syms_of_window): Remove defsubr for Stemp_output_buffer_show.
433 2012-10-17 Eli Zaretskii <eliz@gnu.org>
435 * makefile.w32-in ($(BLD)/w32.$(O)):
436 ($(BLD)/vm-limit.$(O)):
438 ($(BLD)/unexw32.$(O)):
439 ($(BLD)/fileio.$(O)):
440 ($(BLD)/dispnew.$(O)): Update dependencies.
442 * w32term.h (w32_initialize_display_info, initialize_w32_display):
445 * w32proc.c: Include ctype.h.
447 * w32.h (init_environment, check_windows_init_file)
448 (syms_of_ntproc, syms_of_ntterm, dostounix_filename)
449 (unixtodos_filename, init_winsock, srandom, random, sys_pipe)
450 (set_process_dir, sys_spawnve, register_child, sys_sleep, getwd)
451 (sys_link): Add prototypes.
453 * w32.c: Include w32select.h.
454 (sys_access, e_malloc, sys_select): Add prototypes.
455 (emacs_gnutls_pull): 'timeout' is now EMACS_TIME, not struct timeval.
457 * vm-limit.c [WINDOWSNT]: Include w32heap.h.
459 * unexw32.c: Include lisp.h and w32.h.
461 * term.c [WINDOWSNT]: Include w32term.h.
463 * process.c [WINDOWSNT]: Add prototype of sys_select.
465 * fileio.c [WINDOWSNT]: Include w32.h.
467 * dispnew.c [WINDOWSNT]: Include w32.h.
469 * cygw32.c (Fcygwin_convert_path_to_windows)
470 (Fcygwin_convert_path_from_windows): Use EQ to compare 2
471 Lisp_Object values. (Bug#12661)
473 * w32fns.c (w32_msg_pump): Use XIL instead of casting an integer
474 to Lisp_Object. (Bug#12661)
476 2012-10-17 Kenichi Handa <handa@gnu.org>
478 * xdisp.c (reseat_1): Make the information stored in it->cmp_it
481 2012-10-17 Dmitry Antipov <dmantipov@yandex.ru>

510 2012-10-15 Martin Rudalics <rudalics@gmx.at>
512 * window.c (Fwindow_end): Rewrite check whether cached position
513 can be used (Bug#12600).
514 (resize_frame_windows, grow_mini_window, shrink_mini_window):
515 Set windows_or_buffers_changed.

519 * dbusbind.c: Fix cygw32 build break when compiling with dbus
520 enabled by undefining the symbol "interface", which the platform
521 headers define to something incompatible.
523 2012-10-14 Daniel Colascione <dancol@dancol.org>
525 * image.c (init_tiff_functions, init_imagemagick_functions)

548 Fix some stat-related races.
549 * fileio.c (Fwrite_region): Avoid race condition if a file is
550 removed or renamed by some other process immediately after Emacs
551 writes it but before Emacs stats it. Do not assume that stat (or
553 * image.c (slurp_file): Resolve the file name with fopen + fstat

678 Use bool for boolean.
679 * keyboard.c (timers_run, swallow_events)
680 (detect_input_pending_run_timers):
681 * process.c (wait_reading_process_output):
682 Use unsigned for counter where wraparound-on-overflow is desired,
683 since unsigned is guaranteed to have that behavior and signed is not.
684 (read_char): Use ptrdiff_t for string length.
685 (get_input_pending): Remove first argument, since it was always
686 the same pointer-to-int (now pointer-to-boolean) &input_pending,
687 and behave as if it had that value. Return new value of
688 input_pending. All callers changed.
689 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
690 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's
692 * keymap.c (push_key_description): Omit last arg, which was always 1.

706 initializer for PVEC_NORMAL_VECTOR.
708 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
710 Clean out old termopts cruft.
711 * termopts.h (flow_control, meta_key): Remove unused decls.
712 * dispnew.c, indent.c, nsterm.m, term.c, xsettings.c, xsmfns.c:
713 Don't include termopts.h.
715 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>
717 * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers.
719 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
721 * commands.h (immediate_quit): Remove duplicate decl.
723 2012-10-09 Jan Djärv <jan.h.d@swipnet.se>

728 (syms_of_nsfont): Remove initialization of Vfonts_in_cache.
730 2012-10-09 Eli Zaretskii <eliz@gnu.org>
732 * w32fns.c (w32_last_error): Change the return value to DWORD, to
733 match what GetLastError returns. Explain why the function is
736 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
737 'is_tooltip_frame', to avoid confusion with its global namesake.
739 2012-10-08 Daniel Colascione <dancol@dancol.org>
741 * xdisp.c (start_hourglass): Call w32_note_current_window when
742 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
743 build that caused Emacs to display the hourglass cursor forever.
745 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
746 which is broken under remote desktop, calculate the number of
747 colors available for a display based on the display's number of
748 planes and number of bits per pixel per plane. (bug#10397).
750 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
752 * nsfont.m (Vfonts_in_cache): New variable.
753 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
754 are used. Add cached fonts to Vfonts_in_cache.
755 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
757 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
759 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
761 (FONT_H): Define after FRAME_H.
762 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
765 * w32term.c: Remove leftover declaration of keyboard_codepage.
767 2012-10-08 Eli Zaretskii <eliz@gnu.org>
769 * makefile.w32-in (FONT_H): Add $(FRAME_H).
770 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
771 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
772 (GLOBAL_SOURCES): Add cygw32.c.
773 ($(BLD)/unexw32.$(O)):
775 ($(BLD)/w32console.$(O)):
776 ($(BLD)/w32fns.$(O)):
777 ($(BLD)/w32heap.$(O)):
778 ($(BLD)/w32menu.$(O)):
779 ($(BLD)/w32proc.$(O)): Add w32common.h.
781 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
783 (x_to_w32_color): Don't modify the argument, modify a copy instead.
785 2012-10-08 Daniel Colascione <dancol@dancol.org>
787 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
788 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
789 accidental message numbering hole. Change other messages to
792 * w32select.h (HAVE_W32SELECT): Remove.
794 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
795 w32common.h instead of w32heap.h.
797 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
798 (get_allocation_unit, get_processor_type, get_w32_major_version)

805 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
806 (w32_minor_version, w32_build_number, w32_subtype):
807 Remove duplicate definitions.
809 * w32fns.c: Include w32common.h; include w32heap.h only in
812 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
813 Use `report_file_error' instead of `error' in order to better
814 inform users of what went wrong. Increase NTGUI_UNICODE file
815 dialog box file name length to 32k, the maximum allowed by the NT
818 * w32common.h: New file.
819 (ROUND_UP, ROUND_DOWN, get_page_size)
820 (get_allocation_unit, get_processor_type, get_w32_major_version)
821 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
822 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
823 (OS_NT, os_subtype, cache_system_info): Move here.
825 * unexw32.c, unexcw.c: Include w32common.h.
827 * emacs.c (main): Use (defined (WINDOWSNT) || defined
828 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
829 to call syms_of_w32select.
831 * cygw32.h: Remove obsolete EXFUN declarations.
833 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
835 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
836 of w32inevt.o from SOME_MACHINE_OBJECTS.
838 2012-10-08 Daniel Colascione <dancol@dancol.org>
840 * image.c: Permanent fix for JPEG compilation issue --- limit
841 jpeglib `boolean' redefinition to Cygwin builds.
843 2012-10-08 Eli Zaretskii <eliz@gnu.org>
845 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
847 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
850 2012-10-08 Daniel Colascione <dancol@dancol.org>
852 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
853 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
854 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
855 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
856 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
857 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
858 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
859 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
860 now a supported configuration.
862 * Makefile.in: consolidate image variables into LIBIMAGE; add
863 W32_OBJ and W32_LIBS. Compile new files.
866 (_DebPrint) declare tracing facility for W32 debugging. We need
867 to unify tracing later.
869 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
870 unconditional use of W32 Unicode functions. Cygwin runs only on
871 100% Unicode operating systems.
873 * cygw32.c: New file. Define Cygwin-specific facilities.
874 (Fcygwin_convert_path_to_windows)
875 (Fcygwin_convert_path_from_windows): New user functions for
876 accessing Cygwin path-munging routines.
878 * cygw32.h: New file.
879 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
880 UTF-16LE strings temporarily inside non-Lisp-visible string
883 (w32_strerror): Just what it says on the tin.
885 * emacs.c: Make the NS fork-then-exec code for daemon-launching
886 also run for Cygwin; both systems have the same problem with using
887 GUI facilities in a forked child. Also call syms_of_cygw32,
888 syms_of_w32select in correct places.
890 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
891 needs fork-then-exec for daemon launching.
893 * font.h: Include frame.h.
895 * image.c: Use the image library cache machinery only when we're
896 compiling for native WINDOWSNT; Cygwin can use shared libraries
897 like any other Unixlike system.
899 * keyboard.c: Clarify a comment regarding the input loop.
901 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
902 functions directly instead of trying to detect at runtime that our
903 host operating system supports them. We make this change for two
904 reasons: Cygwin lacks support for the multibyte character
905 conversion functions used by the legacy menu code, and Cygwin
906 never needs to rely on non-Unicode APIs.
908 * unexw32.c (hinst): Declare extern.
910 * w32.c: Change header order;
911 (w32_strerror): Move to w32fns.c because we need it for
912 non-WINDOWSNT builds.
914 * w32.h: Add #error macro to make sure we don't include w32.h for
915 Cygwin builds. Remove w32select declarations.
917 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
918 w32fns.c. w32console.c is WINDOWSNT-only.
920 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
921 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
923 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
924 (w32_major_version, w32_minor_version, w32_build_number)
925 (os_subtype, sound_type): Define here
926 (w32_defined_color): Make color parameter const for consistency
927 with other _defined_color functions.
928 (w32_createwindow): Unconditionally call w32_init_class instead of
929 doing so only when hprevinst is non-NULL. Plumbing hprevinst
930 through the code is complex and unnecessary because class
931 registration is practically free.
932 (w32_name_of_message): New EMACSDEBUG-only function.
933 (Fset_message_beep): Move here
934 (Fx_open_connection): Require that the display name for Windows be
935 "w32" for consistency, emacsclient disambiguation, and maybe, one
936 day, multi-window-system support.
937 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
938 Cygwin files for W32 GUI facilities, since these clearly don't
941 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
942 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
943 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
944 (w32_last_error): Remove.
946 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
948 * w32heap.c (syspage_mask): Declare here.
949 (cache_system_info): Remove.
951 * w32inevt.c (faked_key): Define globally, not statically.
952 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
953 (w32_console_toggle_lock_key): Move to w32fns.c.
955 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
957 * w32proc.c (_DebPrint): Move to w32fns.c.
958 * w32select.c: Include string.h, stdio.h for Cygwin.
959 * w32select.h: New File.
961 * w32term.c: Include io.h for non-CYGWIN builds; needed for
963 (w32_message_fd): New variable. Under Cygwin, holds the file
964 descriptor the system used to tell us about pending thread
967 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
968 that prevented compilation under non-WINDOWSNT systems.
970 (w32_initialize): Open /dev/windows and assign it to
971 w32_message_fd. Provide w32 feature.
973 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
974 (WM_EMACS_INPUT_READY): add.
975 (prepend_msg, w32_message_fd): Declare globally.
978 (keyboard_handle): Use only when WINDOWSNT.
979 (notify_msg_ready): New function. Posts a message to the main
980 thread's message queue under CYGWIN, which wakes up the main
981 thread from select(2) by making the /dev/windows file descriptor
982 ready. Under WINDOWSNT, it sets an event the same way the old
985 (post, prepend_msg): Actually call notify_msg_ready instead of
986 setting the input event directly.
988 2012-10-07 Eli Zaretskii <eliz@gnu.org>
990 * ralloc.c (relinquish): If a heap is ready to be relinquished,
991 but it still has blocs in it, don't return it to the system,
992 instead of aborting. (Bug#12402)
994 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
996 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
998 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
999 MAC_OS_X_VERSION_10_6.
1000 (syms_of_nsterm): Remove comment about Panther and above for
1002 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.

1004 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
1006 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
1007 MAC_OS_X_VERSION_10_4.
1009 * nsmenu.m (fillWithWidgetValue:): Remove code for <
1010 MAC_OS_X_VERSION_10_2.
1012 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.

1029 Improve sys_siglist detection.
1030 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
1031 defined as a macro, as is done in Solaris.
1032 (sys_siglist_entries): New macro.
1033 (save_strsignal): Use it.
1034 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
1035 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
1037 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
1039 * nsfns.m (Fx_create_frame): Call x_default_parameter with
1040 fullscreen/Fullscreen.
1042 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
1043 tobar_height is new.
1045 * nsterm.m (x_make_frame_visible): Check for fullscreen.
1046 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
1047 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.

1060 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
1062 2012-10-05 Eli Zaretskii <eliz@gnu.org>
1064 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
1066 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
1067 that time stamps of directories could also be changed.
1068 Don't request the too broad GENERIC_WRITE, only the more restrictive
1069 FILE_WRITE_ATTRIBUTES access rights.
1071 * fileio.c (Fset_file_times): Special-case ignoring errors for
1072 directories only on MSDOS, not on MS-Windows.
1074 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
1076 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
1078 2012-10-04 Eli Zaretskii <eliz@gnu.org>

1083 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
1085 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
1086 to avoid similar races.
1087 * keyboard.c (pending_signals): Now bool, not int.
1089 Port timers to OpenBSD, plus check for timer failures.
1090 OpenBSD problem reported by Han Boetes.
1091 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
1093 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
1094 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
1095 like OpenBSD, which has timer_settime but does not declare it.
1096 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
1097 whether to use itimerspec-related primitives. All uses of
1098 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
1100 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
1102 * profiler.c (handle_profiler_signal): Fix a malloc race
1103 that caused Emacs to hang on Fedora 17 when profiling Lisp.

1107 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
1109 2012-10-02 Eli Zaretskii <eliz@gnu.org>
1111 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
1112 consistent with the change in return value of 'safe_strsignal'.
1114 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
1116 Prefer plain 'static' to 'static inline' (Bug#12541).
1117 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
1118 (bidi_set_sor_type, bidi_push_embedding_level)
1119 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)

1124 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
1125 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
1126 Now 'static', not 'static inline'.
1128 Count overruns when profiling; change units to ns.
1129 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
1130 Give extra weight to samples after overruns, to attempt to count
1131 the time more accurately.
1132 (setup_cpu_timer): Change sampling interval units from ms to ns, since
1133 the underlying primitives nominally do ns.
1134 (Fprofiler_cpu_start): Document the change. Mention that
1135 the sampling intervals are only approximate.
1137 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
1139 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
1141 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
1142 case for the special 0 coding-system.
1144 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
1145 (Fmake_overlay): Remove redundant tests.
1146 (fix_start_end_in_overlays): Remove redundant recentering.
1148 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
1150 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
1151 Update dependencies.
1153 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
1155 Fix a malloc race condition involving strsignal.
1156 A signal can arrive in the middle of a malloc, and Emacs's signal
1157 handler can invoke strsignal, which can invoke malloc, which is
1158 not portable. This race condition bug makes Emacs hang on GNU/Linux.
1159 Fix it by altering the signal handler so that it does not invoke
1161 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
1162 * process.c (status_message): Use const pointer, in case strsignal
1163 is #defined to safe_strsignal.
1164 * sysdep.c (sys_siglist, init_signals): Always define and
1165 initialize a substitute sys_siglist if the system does not define
1166 one, even if HAVE_STRSIGNAL.
1167 (safe_strsignal): Rename from strsignal. Always define,
1168 using sys_siglist. Return a const pointer.
1169 * syssignal.h (safe_strsignal): New decl.
1170 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
1172 2012-10-01 Eli Zaretskii <eliz@gnu.org>
1174 * w32proc.c (timer_loop): Fix code that waits for timer
1175 expiration, to avoid high CPU usage.
1177 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
1179 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
1180 (sweep_weak_table): Remove redundant prototypes.
1182 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
1184 * emacs.c: Move the inclusion of TERM_HEADER after including
1185 windows.h on WINDOWSNT. This avoids compilation problems with
1188 2012-10-01 Eli Zaretskii <eliz@gnu.org>
1190 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
1191 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
1192 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
1193 as the previous version used 'void *'.
1195 * ralloc.c (ROUNDUP): Fix last change.
1196 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
1199 * w32proc.c <disable_itimers>: New static flag.
1200 (init_timers): Initialize it to zero, after creating the critical
1201 sections used by the timer threads.
1202 (term_timers): Set to 1 before deleting the critical sections.
1203 (getitimer, setitimer): If disable_itimers is non-zero, return an
1204 error indication without doing anything. Reported by Fabrice
1205 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
1206 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
1208 [!HAVE_SETITIMER]: Behave as the previous version that didn't
1211 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
1212 term_ntproc after all the other bookkeeping, to get timers working
1213 as long as possible.
1215 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
1217 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
1218 Suggested by Juri Linkov in
1219 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
1221 Prefer plain 'static' to 'static inline' (Bug#12541).
1222 With static functions, modern compilers inline pretty well by
1223 themselves; advice from programmers often hurts as much as it helps.
1224 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
1225 this change shrinks the text size of the Emacs executable by 1.1%
1226 without affecting CPU significantly in my benchmark.
1227 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)

1307 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
1309 Revert the FOLLOW-SYMLINKS change for file-attributes.
1310 Doing it right would require several changes to Tramp, and there's
1311 not enough time to get that tested before the freeze today.
1312 * dired.c (directory_files_internal, Ffile_attributes):
1315 * frame.c (x_report_frame_params): Port better to wider ints.
1316 Do not assume that EMACS_UINT is the same width as uprintmax_t,
1317 or that pointers can be printed in 15 decimal digits.
1318 Avoid GCC warnings if EMACS_UINT is wider than a pointer.

1479 (EmacsView): Add variables for fullscreen.
1480 (handleFS, setFSValue, toggleFullScreen): New in EmacsView.
1481 (EmacsFSWindow): New interface for fullscreen.
1483 2012-09-30 Juanma Barranquero <lekktu@gmail.com>
1485 * makefile.w32-in ($(BLD)/profiler.$(O)): Update dependencies.
1487 2012-09-30 Chong Yidong <cyd@gnu.org>
1489 * fns.c (Frandom): Doc fix.
1491 2012-09-30 Martin Rudalics <rudalics@gmx.at>
1493 * window.c (Vwindow_combination_limit): New default value.
1494 (Qwindow_size): New symbol replacing Qtemp_buffer_resize.
1496 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
1498 * syssignal.h (PROFILER_CPU_SUPPORT): Don't define if PROFILING.
1499 Suggested by Eli Zaretskii in
1500 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00811.html>.
1502 2012-09-30 Eli Zaretskii <eliz@gnu.org>
1504 * profiler.c (Fprofiler_cpu_stop): Use timer_settime only if
1505 HAVE_TIMER_SETTIME is defined.
1507 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
1509 Profiler improvements: more-accurate timers, overflow checks.
1510 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
1511 signal.h, setjmp.h. Include systime.h instead.
1512 (saturated_add): New function.
1513 (record_backtrace, current_sample_interval): Use EMACS_INT, not size_t.
1514 (record_backtrace, handle_profiler_signal): Saturate on fixnum overflow.
1515 (profiler_timer, profiler_timer_ok) [HAVE_TIMER_SETTIME]:
1517 (enum profiler_cpu_running): New enum.
1518 (profiler_cpu_running): Now of that enum type, not bool.
1519 All uses changed to store the new value.
1520 (handle_profiler_signal): Rename from sigprof_handler_1,
1521 for consistency with other handlers. Do not check whether
1522 cpu_log is a hash-table if garbage collecting, since it
1523 doesn't matter in that case.
1524 (deliver_profiler_signal): Rename from sigprof_handler,
1525 for consistency with other handlers.
1526 (setup_cpu_timer): New function, with much of what used to be in
1527 Fprofiler_cpu_start. Check for out-of-range argument.
1528 Prefer timer_settime if available, and prefer
1529 thread cputime clocks, then process cputime clocks, then
1530 monotonic clocks, to the old realtime clock. Use make_timeval
1531 to round more-correctly when falling back to setitimer.
1532 (Fprofiler_cpu_start): Use it.
1533 (Fprofiler_cpu_stop): Prefer timer_settime if available.
1534 Don't assume that passing NULL as the 2nd argument of setitimer
1535 is the same as passing a pointer to all-zero storage.
1536 Ignore SIGPROF afterwards.
1537 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
1538 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
1539 non-fatal signal handlers. Ignore SIGPROF on startup.
1540 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
1541 in profiler.c, since sysdep.c now uses it.
1543 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.
1544 Suggested by Eli Zaretskii in

1597 * character.h (MAYBE_UNIFY_CHAR): Remove.
1598 * charset.c, charset.h (maybe_unify_char): Now static.
1599 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
1600 Since this stuff is now private to charset.c, there's no need for
1601 a public macro and no need to inline by hand.

1634 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>
1636 Prefer POSIX timers if available.
1637 They avoid a race if the timer is too close to the current time.

1665 * w32.h (Vlibrary_cache): Do not declare.
1667 2012-09-25 Eli Zaretskii <eliz@gnu.org>
1669 * w32proc.c (sys_signal): Handle all signals defined by the
1670 MS-Windows runtime, not just SIGCHLD. Actually install the signal
1671 handlers for signals supported by Windows. Don't override
1672 term_ntproc as the handler for SIGABRT.
1673 (sigaction): Rewrite to call sys_signal instead of duplicating its
1675 (sys_kill): Improve commentary.
1677 * w32.c (term_ntproc): Accept (and ignore) one argument, for
1678 consistency with a signature of a signal handler. All callers
1680 (init_ntproc): Accept an argument DUMPING. If dumping, don't
1681 install term_ntproc as a signal handler for SIGABRT, as that
1682 should be done by the dumped Emacs.
1684 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
1686 * w32select.c (term_w32select): Protect against repeated
1687 invocation by setting clipboard_owner to NULL after calling
1690 * emacs.c (shut_down_emacs, main): Adapt the calls to init_ntproc
1691 and term_ntproc to their modified signatures.
1693 * character.c (char_string, string_char): Remove calls to

1705 when encountering an unknown bytecode.
1707 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
1709 image.c, indent.c: Use bool for booleans.

1712 * image.c: Omit unnecessary static decls.
1713 (x_create_bitmap_mask, x_build_heuristic_mask):

1751 Move pid_t related decls out of lisp.h.
1752 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
1753 (interruptible_wait_for_termination):
1754 Move these decls from lisp.h to syswait.h, since they use pid_t.
1755 Needed on FreeBSD; see Herbert J. Skuhra in
1756 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.

1803 2012-09-23 Eli Zaretskii <eliz@gnu.org>
1805 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
1806 fatal_error_backtrace.
1808 * w32proc.c (sys_kill): Undo last change: don't do anything when
1809 invoked to deliver SIGABRT to our own process. This is now
1810 handled by emacs_raise.
1812 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
1814 * w32term.c (w32_read_socket): Remove leftover reference to
1815 interrupt_input_pending.
1817 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
1819 Do not use SA_NODEFER.
1820 Problem reported by Dani Moncayo in
1821 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
1823 * sysdep.c (emacs_abort): Do not reset signal handler.
1824 * emacs.c (terminate_due_to_signal): Reset signal handler here.
1825 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
1826 wanted even on POSIXish hosts, and it doesn't work on Windows.
1828 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
1830 * xterm.c (x_term_init): Call fixup_locale before and after calling
1831 gtk_init (Bug#12392).
1833 2012-09-23 Chong Yidong <cyd@gnu.org>
1835 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
1836 Vdynamic_library_alist.
1838 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
1839 (Fgnutls_available_p): Caller changed.
1841 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
1842 (Flibxml_parse_xml_region): Likewise.
1844 * dispextern.h (struct image_type): Remove arg from init function.
1846 * image.c (Finit_image_library, lookup_image_type)
1847 (define_image_type): Remove now-unneeded second arg.
1848 (init_xpm_functions, init_png_functions, init_jpeg_functions)
1849 (init_tiff_functions, init_gif_functions, init_svg_functions):
1850 Arglist and w32_delayed_load calling convention changed.
1851 (gs_type): Remove init_gs_functions; there is no such function.
1852 (valid_image_p, make_image): Fix caller to lookup_image_type.
1854 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
1856 Simplify and avoid signal-handling races (Bug#12471).
1858 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
1859 Avoid recursive loop if there's a fatal error in the function itself.
1860 * atimer.c (pending_atimers):
1861 * blockinput.h: Don't include "atimer.h"; no longer needed.
1862 (interrupt_input_pending): Remove. All uses removed.
1863 pending_signals now counts both atimers and ordinary interrupts.
1864 This is less racy than having three separate pending-signal flags.
1865 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
1867 Rename from their upper-case counterparts BLOCK_INPUT,
1868 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
1869 INPUT_BLOCKED_P, and turn into functions. All uses changed.
1870 This makes it easier to access volatile variables more accurately.
1871 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
1872 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
1873 that's more reliable if the code is buggy and sets
1874 interrupt_input_blocked to a negative value. All uses changed.
1875 * atimer.c (deliver_alarm_signal):
1876 Remove. No need to deliver this to the parent; any thread can
1877 handle this signal now. All uses replaced by underlying handler.
1878 * atimer.c (turn_on_atimers):
1879 * dispnew.c (handle_window_change_signal):
1880 * emacs.c (handle_danger_signal):
1881 * keyboard.c (kbd_buffer_get_event):
1882 Don't reestablish signal handler; not needed with sigaction.
1883 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
1885 Rework to avoid unnecessary accesses to volatile variables.
1886 (UNBLOCK_INPUT_TO): Now a function.
1887 (totally_unblock_input, unblock_input): New decls.
1888 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
1889 (init_data): Remove. Necessary stuff now done in init_signal.
1890 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
1891 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
1892 (fatal_error_code): Remove; no longer needed.
1893 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
1894 it doesn't always backtrace. All uses changed. No need to reset
1895 signal to default, since sigaction and/or die does that for us now.
1896 Use emacs_raise (FOO), not kill (getpid (), FOO).
1897 (main): Check more-accurately whether we're dumping.
1898 Move fatal-error setup to sysdep.c
1899 * floatfns.c: Do not include "syssignal.h"; no longer needed.
1900 * gtkutil.c (xg_get_file_name, xg_get_font):
1901 Remove no-longer-needed signal-mask manipulation.
1902 * keyboard.c, process.c (POLL_FOR_INPUT):
1903 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
1904 * keyboard.c (read_avail_input): Remove.
1905 All uses replaced by gobble_input.
1906 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
1907 (kbd_buffer_store_event_hold, gobble_input):
1908 (record_asynch_buffer_change) [USABLE_SIGIO]:
1909 (store_user_signal_events):
1910 No need to mess with signal mask.
1911 (gobble_input): If blocking input and there are terminals, simply
1912 set pending_signals to 1 and return. All hooks changed to not
1913 worry about whether input is blocked.
1914 (process_pending_signals): Clear pending_signals before processing
1915 them, in case a signal comes in while we're processing.
1916 By convention callers now test pending_signals before calling us.
1917 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
1918 New functions, to support changes to blockinput.h.
1919 (handle_input_available_signal): Now extern.
1920 (reinvoke_input_signal): Remove. All uses replaced by
1922 (quit_count): Now volatile, since a signal handler uses it.
1923 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
1924 All callers changed. Block SIGINT only if not already blocked.
1925 Clear sigmask reliably, even if Fsignal returns, which it can.
1926 Omit unnecessary accesses to volatile var.
1927 (quit_throw_to_read_char): No need to restore sigmask.
1928 * keyboard.c (gobble_input, handle_user_signal):
1929 * process.c (wait_reading_process_output):
1930 Call signal-handling code rather than killing ourselves.
1931 * lisp.h: Include <float.h>, for...
1932 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
1933 (pending_signals): Now volatile.
1934 (syms_of_data): Now const if IEEE floating point.
1935 (handle_input_available_signal) [USABLE_SIGIO]:
1936 (terminate_due_to_signal, record_child_status_change): New decls.
1937 * process.c (create_process): Avoid disaster if memory is exhausted
1938 while we're processing a vfork, by tightening the critical section
1940 (send_process_frame, process_sent_to, handle_pipe_signal)
1941 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
1943 (send_process): No need for setjmp/longjmp any more, since the
1944 SIGPIPE stuff is now gone. Instead, report an error if errno
1946 (record_child_status_change): Now extern. PID and W are now args.
1947 Return void, not bool. All callers changed.
1948 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
1949 Remove. All uses removed. This bug should be fixed now in a
1951 (wait_for_termination_1): Use waitpid rather than sigsuspend,
1952 and record the child status change directly. This avoids the
1953 need to futz with the signal mask.
1954 (process_fatal_action): Move here from emacs.c.
1955 (emacs_sigaction_flags): New function, containing
1956 much of what used to be in emacs_sigaction_init.
1957 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
1958 caught by emacs, to make races less likely.
1959 (deliver_process_signal): Rename from handle_on_main_thread.
1961 (BACKTRACE_LIMIT_MAX): Now at top level.
1962 (thread_backtrace_buffer, threadback_backtrace_pointers):
1964 (deliver_thread_signal, deliver_fatal_thread_signal):
1965 New functions, for more-accurate delivery of thread-specific signals.
1966 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
1967 (deliver_arith_signal): Handle in this thread, not
1968 in the main thread, since it's triggered by this thread.
1969 (maybe_fatal_sig): New function.
1970 (init_signals): New arg DUMPING so that we can be more accurate
1971 about whether we're dumping. Caller changed.
1972 Treat thread-specific signals differently from process-general signals.
1973 Block all signals while handling fatal error; that's safer.
1974 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
1976 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
1977 Ignore SIGPIPE unless batch.
1978 (emacs_backtrace): Output backtrace for the appropriate thread,
1979 which is not necessarily the main thread.
1980 * syssignal.h: Include <stdbool.h>.
1981 (emacs_raise): New macro.
1982 * xterm.c (x_connection_signal): Remove; no longer needed
1983 now that we use sigaction.
1984 (x_connection_closed): No need to mess with sigmask now.
1985 (x_initialize): No need to reset SIGPIPE handler here, since
1986 init_signals does this for us now.
1988 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
1990 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
1991 background rect may be larger (Bug#12245).
1993 2012-09-23 Chong Yidong <cyd@gnu.org>
1995 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
1997 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
1999 * .gdbinit: Just stop at fatal_error_backtrace.
2000 See Stefan Monnier's request in
2001 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
2002 Remove no-longer-used query of system type.
2004 2012-09-22 Chong Yidong <cyd@gnu.org>
2006 * search.c (Freplace_match): Doc fix (Bug#12325).
2008 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
2010 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
2011 (Fline_end_position): Doc fix.
2013 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
2015 2012-09-22 Chong Yidong <cyd@gnu.org>
2017 * dispextern.h (struct image_type): Add new slot, storing a type
2018 initialization function.
2020 * image.c (define_image_type): Call the image initializer function
2021 if it is defined. Arguments and return value changed.
2022 (valid_image_p, make_image): Callers changed.
2023 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
2024 (gif_type, imagemagick_type, svg_type, gs_type):
2025 Add initialization functions.
2026 (Finit_image_library): Call lookup_image_type.
2027 (CHECK_LIB_AVAILABLE): Macro deleted.
2028 (lookup_image_type): Call define_image_type here, rather than via
2029 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
2030 (syms_of_image): Move define_image_type calls for xbm_type and
2031 pbm_type to lookup_image_type.
2033 2012-09-22 Eli Zaretskii <eliz@gnu.org>
2035 * keyboard.c (timer_check_2): Move calculation of 'timers' and
2036 'idle_timers' from here ...
2037 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
2038 lists, to avoid infloops when the timer does something stupid,
2039 like reinvoke itself with the same or smaller time-out.
2042 2012-09-22 Martin Rudalics <rudalics@gmx.at>
2044 * window.c (Fsplit_window_internal): Handle only Qt value of
2045 Vwindow_combination_limit separately.
2046 (Qtemp_buffer_resize): New symbol.
2047 (Vwindow_combination_limit): New default value.
2050 2012-09-22 Eli Zaretskii <eliz@gnu.org>
2052 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
2053 the new overlay string. (Bug#10159)
2055 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
2057 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
2058 or that fprintf is async-signal-safe. POSIX doesn't require
2061 2012-09-22 Chong Yidong <cyd@gnu.org>
2063 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
2066 2012-09-22 Kenichi Handa <handa@gnu.org>
2068 * composite.c (composition_reseat_it): Handle the case that a
2069 grapheme cluster is not covered by a single font (Bug#12352).
2071 2012-09-21 Chong Yidong <cyd@gnu.org>
2073 * image.c (define_image_type): Avoid adding duplicate types to
2074 image_types (Bug#12463). Suggested by Jörg Walter.
2076 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2078 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
2079 (print_load_command_name): Add case LC_DATA_IN_CODE.
2080 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
2082 2012-09-21 Glenn Morris <rgm@gnu.org>
2084 * eval.c (Frun_hook_with_args_until_success)
2085 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
2087 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
2089 * fileio.c (Ffile_selinux_context): Only call freecon when
2090 lgetfilecon succeeded.
2091 (Fset_file_selinux_context): Likewise. (Bug#12444)
2093 2012-09-21 Eli Zaretskii <eliz@gnu.org>
2095 * xdisp.c (try_window_reusing_current_matrix): Under bidi
2096 reordering, locate the cursor by calling set_cursor_from_row; if
2097 that fails, clear the desired glyph matrix before returning a
2098 failure indication to the caller. Fixes leaving garbled display
2099 when fast scrolling with a down-key. (Bug#12403)
2100 (compute_stop_pos_backwards): Fix a typo that caused crashes while
2101 scrolling through multibyte text.
2103 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
2105 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
2106 calling mark_vectorlike since that's the one that marks the window.
2107 (mark_discard_killed_buffers): Mark the final cdr.
2108 * window.h (struct window): Move prev/next_buffers to the
2109 non-standard fields.
2110 * window.c (make_window): Initialize prev/next_buffers manually.
2112 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
2114 Omit unused arg EXPECTED from socket hooks.
2115 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
2116 * nsterm.m (ns_term_init):
2117 * termhooks.h (struct terminal.read_socket_hook):
2118 * w32inevt.c (w32_console_read_socket):
2119 * w32term.c (w32_read_socket):
2120 * xterm.c (XTread_socket):
2121 Omit unused arg EXPECTED. All callers changed.
2122 (store_user_signal_events): Return void, not int, since callers no
2123 longer care about the return value. All uses changed.
2125 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
2127 * w32gui.h (XParseGeometry): Do not declare.
2129 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
2131 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
2132 Ignore 'expected'. See Eli Zaretskii in
2133 <http://bugs.gnu.org/12471#8> (last line).
2135 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
2136 (XParseGeometry): Now static. Substitute extremal values for
2137 values that are out of range.
2139 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
2141 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
2143 * nsfns.m (XParseGeometry): Remove.
2144 (Fx_create_frame): Call x_set_offset to correctly interpret
2145 top_pos in geometry.
2147 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
2148 (Fx_parse_geometry): If there is a space in string, call
2149 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
2151 2012-09-17 Eli Zaretskii <eliz@gnu.org>
2153 * search.c (scan_buffer): Use character positions in calls to
2154 region_cache_forward and region_cache_backward, not byte
2155 positions. (Bug#12196)
2157 * w32term.c (w32_read_socket): Set pending_signals to 1, like
2158 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
2160 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
2161 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
2162 emacs_blocked_malloc, now deleted.
2164 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
2166 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
2167 The workaround was for improving performance on Solaris 2.4, but
2168 is getting in the way now. Emacs will still work if someone is
2169 still running Solaris 2.4 in a museum somewhere; Sun dropped
2170 support for Solaris 2.4 in 2003.
2171 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
2172 * process.c (create_process) [HAVE_WORKING_VFORK]:
2173 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
2174 since Emacs no longer uses vfork on that platform.
2176 2012-09-17 Glenn Morris <rgm@gnu.org>
2178 * emacs.c: Use COPYRIGHT.
2180 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
2182 Remove configure's --without-sync-input option (Bug#12450).
2183 When auditing signal-handling in preparation for cleaning it up,
2184 I found that SYNC_INPUT has race conditions and would be a real
2185 pain to fix. Since it's an undocumented and deprecated
2186 configure-time option, now seems like a good time to remove it.
2187 Also see <http://bugs.gnu.org/11080#16>.
2188 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
2189 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
2190 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
2191 (malloc_hysteresis):
2192 (check_depth) [XMALLOC_OVERRUN_CHECK]:
2193 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
2194 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
2195 (dont_register_blocks, bytes_used_when_reconsidered)
2196 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
2197 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
2198 [!SYSTEM_MALLOC && !SYNC_INPUT]:
2199 Remove. All uses removed.
2200 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
2201 implementation, one that depends on whether the new macro
2202 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
2204 * atimer.c (run_timers, handle_alarm_signal):
2205 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
2206 (handle_async_input, process_pending_signals)
2207 (handle_input_available_signal, init_keyboard):
2208 * nsterm.m (ns_read_socket):
2209 * process.c (wait_reading_process_output):
2210 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
2211 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
2213 * xterm.c (XTread_socket):
2215 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
2216 * eval.c (handling_signal): Remove. All uses removed.
2217 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
2218 All uses replaced with the SYNC_INPUT version.
2219 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
2221 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
2224 * font.c (Ffont_shape_gstring): Remove unused local.
2226 2012-09-16 Glenn Morris <rgm@gnu.org>
2228 * Makefile.in (clean): No longer run nextstep's clean.
2230 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
2232 (ns-app): Move here from ns.mk, and simplify.
2233 (clean): Simplify nextstep entry.
2234 * ns.mk: Remove file.
2236 2012-09-17 Kenichi Handa <handa@gnu.org>
2238 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
2239 not covert the last few charactes.
2241 2012-09-16 Kenichi Handa <handa@gnu.org>
2243 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
2244 here, but just check the validity of glyphs in the glyph-string.
2246 2012-09-16 Martin Rudalics <rudalics@gmx.at>
2248 * window.c (Fwindow_parameter, Fset_window_parameter):
2249 Accept any window as argument (Bug#12452).
2251 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
2253 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
2254 to ns_term_init to avoid memory leak.
2256 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
2257 explicit retain/release.
2258 (ns_term_init): Only allow one display. Initialize outerpool and
2261 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
2263 Port _setjmp fix to POSIXish hosts as well as Microsoft.
2264 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
2265 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
2266 the Microsoft problem in a different way, by altering ../nt/config.nt.
2268 2012-09-15 Eli Zaretskii <eliz@gnu.org>
2283 * w16select.c: Remove inclusion of setjmp.h, as it is now included
2284 by lisp.h. This completes removal of setjmp.h inclusion
2285 erroneously announced in the previous commit. (Bug#12446)
2287 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
2290 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
2291 not defined as a macro. The latter happens on MS-Windows.
2294 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
2296 Port better to POSIX hosts lacking _setjmp (Bug#12446).
2297 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
2298 Some instances of '#include <setjmp.h>' removed, if the
2299 only reason for the instance was because "lisp.h" was included.
2300 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
2301 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
2302 and _longjmp with the new symbols. Emacs already uses _setjmp if
2303 available, so this change affects only POSIXish hosts that have
2304 sigsetjmp but not _setjmp, such as some versions of Solaris and
2305 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
2306 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
2307 (png_load_body) [HAVE_PNG]:
2308 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
2309 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
2310 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
2311 since PNG requires jmp_buf. This is the only exception to the
2312 general rule that we now use sys_setjmp and sys_longjmp.
2313 This exception is OK since this code does not change the signal
2314 mask or longjmp out of a signal handler.
2316 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
2318 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
2319 Include "syssignal.h", for 'main_thread'.
2321 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
2323 Avoid out-of-range marker position (Bug#12426).
2324 * insdel.c (replace_range, replace_range_2):
2325 Adjust markers before overlays, as suggested by comments.
2326 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
2327 Remove redundant check before calling offset_intervals.
2329 2012-09-14 Martin Rudalics <rudalics@gmx.at>
2331 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
2332 current buffer (Bug#12387).
2334 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
2336 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
2338 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
2340 Use a more backwards-compatible timer format (Bug#12430).
2341 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
2342 vector element, not from the 4th, since PSECS is now at the end.
2343 (Fcurrent_idle_time): Doc fix.
2345 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
2347 Function to mark objects and remove killed buffers at once.
2348 * alloc.c (discard_killed_buffers): Rename to ...
2349 (mark_discard_killed buffers) ... new name. Add marking
2350 of remaining objects. Fix comment. Adjust users.
2351 (mark_object): Do not touch frame buffer lists here.
2352 * frame.c (delete_frame): Reset frame buffer lists here.
2354 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
2356 Better workaround for GNOME bug when --enable-gcc-warnings.
2357 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
2358 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
2359 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
2361 Simplify SIGIO usage (Bug#12408).
2362 The code that dealt with SIGIO was crufty and confusing, e.g., it
2363 played tricks like "#undef SIGIO" but these tricks were not used
2364 consistently. Simplify mostly by not #undeffing standard symbols,
2365 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
2366 or not as we please) rather than "defined SIGIO" (standard symbol
2367 that we probably shouldn't #undef).
2368 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
2369 Modules that need it can include it.
2370 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
2371 * dispextern.h (ignore_sigio): New decl.
2372 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
2373 unconditionally, since it's now a no-op if !USABLE_SIGIO.
2374 * emacs.c (shut_down_emacs):
2375 * keyboard.c (kbd_buffer_store_event_hold):
2376 Use ignore_sigio rather than invoking 'signal' directly.
2377 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
2379 (FIONREAD, SIGIO): Do not #undef.
2380 (tty_read_avail_input): Use #error rather than a syntax error.
2381 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
2382 for I_PIPE, used by SETUP_SLAVE_PTY.
2383 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
2384 * sysdep.c (croak): Remove; no longer needed. This bit of
2385 temporary code, with Fred N. Fish's comment that it's temporary,
2386 has been in Emacs since at least 1992!
2387 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
2388 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
2389 * syssignal.h (croak): Remove decl.
2390 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
2391 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
2392 now that we're termios-only.
2393 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
2394 * term.c (dissociate_if_controlling_tty): Use #error rather than
2397 Work around GCC and GNOME bugs when --enable-gcc-warnings.
2398 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
2399 to work around GNOME bug 683906.
2400 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
2401 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
2402 This works around GCC bug 54561.
2404 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
2406 More fixes for 'volatile' and setjmp/longjmp.
2407 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
2408 * image.c (struct png_load_context) [HAVE_PNG]: New type.
2409 (png_load_body) [HAVE_PNG]:
2410 (jpeg_load_body) [HAVE_JPEG]:
2411 New function, with most of the old parent function's body.
2412 (png_load) [HAVE_PNG]:
2413 (jpeg_load) [HAVE_JPEG]:
2414 Invoke the new function, to avoid longjmp munging our locals.
2415 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
2416 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
2417 longjmp is passed 2, as the C standard doesn't guarantee this.
2418 Instead, store the failure code into mgr->failure_code.
2420 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
2422 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
2423 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
2424 (syms_of_keyboard): Remove support for unread-command-char.
2426 2012-09-12 Eli Zaretskii <eliz@gnu.org>
2428 * w32proc.c (sys_kill): If PID is our process ID and the signal is
2429 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
2430 violation. (Bug#12426)
2432 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
2434 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
2436 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
2438 * eval.c: Add `inhibit-debugger'.
2439 (Qinhibit_debugger): New symbol.
2440 (call_debugger): Bind it instead of Qdebug_on_error.
2441 (maybe_call_debugger): Test Vinhibit_debugger.
2442 (syms_of_eval): Define inhibit-debugger.
2443 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
2444 (syms_of_xdisp): Remove inhibit-debug-on-message.
2446 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
2448 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
2449 If a nonvolatile local variable is written before a _longjmp to
2450 the frame containing the variable, and is read after the _longjmp,
2451 the value read is indeterminate. Some local variables of type
2452 'struct handler' and 'struct catchtag' are used in this way, so
2453 mark each of their slots as volatile if the slot can be set before
2454 _longjmp and read afterwards.
2455 * lisp.h (struct handler): var and chosen_clause are now volatile.
2456 (struct catchtag): val, next, and pdlcount are now volatile.
2458 * bidi.c (bidi_push_it, bidi_pop_it):
2459 * fns.c (copy_hash_table):
2460 * image.c (define_image_type):
2461 * keyboard.c (kbd_buffer_store_event_hold):
2462 * process.c (Fprocess_send_eof):
2463 * xfaces.c (x_create_gc) [HAVE_NS]:
2464 * xgselect.c (xg_select):
2465 Prefer assignment to memcpy when either will do.
2467 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
2468 Use pointer-to-a-pointer to simplify and avoid a NILP check each
2469 time an item is removed. No need to mark this function 'inline';
2470 the compiler knows better than we do.
2472 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
2474 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
2475 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
2476 to change_frame_size (Bug#12388).
2477 (windowDidResize:): Pass YES to updateFrameSize.
2479 * nsterm.h: Add delay parameter to updateFrameSize.
2481 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
2483 Discard killed buffers from deleted window and frame objects.
2484 This reduces an amount of references to killed buffers and
2485 helps GC to reclaim them faster.
2486 * alloc.c (discard_killed_buffers): New function.
2487 (mark_object): Use it for deleted windows and frames.
2488 (mark_object): If symbol's value is set up for a killed buffer
2489 or deleted frame, restore its global binding.
2490 * data.c (swap_in_global_binding): Add GC notice.
2491 (swap_in_symval_forwarding): Use convenient set_blv_where.
2492 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
2493 * window.h: ... to here.
2495 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
2497 Convenient macro to check whether the buffer is live.
2498 * buffer.h (BUFFER_LIVE_P): New macro.
2499 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
2500 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
2502 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2504 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
2505 composition cases (Bug#12364).
2507 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
2508 overhang of succeeding glyphs overlapping box cursor.
2510 * w32term.c (x_draw_glyph_string): Likewise.
2512 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
2514 Simplify, document, and port floating-point (Bug#12381).
2515 The porting part of this patch fixes bugs on non-IEEE platforms
2516 with frexp, ldexp, logb.
2517 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
2519 * floatfns.c: Simplify discussion of functions that Emacs doesn't
2520 support, by removing commented-out code and briefly listing the
2521 C89 functions excluded. The commented-out stuff was confusing
2522 maintenance, e.g., we thought we needed cbrt but it was commented out.
2523 (logb): Remove decl; no longer needed.
2524 (isfinite): New macro, if not already supplied.
2525 (isnan): Don't replace any existing macro.
2526 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
2527 are present on all C89 platforms.
2528 (Ffrexp): Do not special-case zero, as frexp does the right thing
2530 (Flogb): Do not use logb, as it doesn't have the desired meaning
2531 on hosts that use non-base-2 floating point. Instead, stick with
2532 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
2533 frexp, to avoid getting an unspecified result.
2535 * xdisp.c (Qinhibit_debug_on_message): Now static.
2537 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
2539 * nsterm.m (ns_update_begin): Set clip path to whole view by using
2540 NSBezierPath (Bug#12131).
2542 2012-09-10 Chong Yidong <cyd@gnu.org>
2544 * fns.c (Fdelq, Fdelete): Doc fix.
2546 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
2548 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
2549 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
2551 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
2553 * lisp.h (make_lisp_ptr): New macro to replace XSET.
2554 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
2557 2012-09-09 Eli Zaretskii <eliz@gnu.org>
2559 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
2560 left fringe if the window has a left margin. This avoids leaving
2561 traces of the cursor because its leftmost pixel is not drawn over.
2563 * dispnew.c (update_window_line): When the left margin area of a
2564 screen line is updated, set the redraw_fringe_bitmaps_p flag of
2565 that screen line. (Bug#12277)
2567 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
2569 Assume C89 or later for math functions (Bug#12381).
2570 This simplifies the code, and makes it a bit smaller and faster,
2571 and (most important) makes it easier to clean up signal handling
2572 since we can stop worring about floating-point exceptions in
2573 library code. That was a problem before C89, but the problem
2574 went away many years ago on all practical Emacs targets.
2575 * data.c, image.c, lread.c, print.c:
2576 Don't include <math.h>; no longer needed.
2577 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
2578 might be autoconfigured, as that never happens.
2580 * doprnt.c (DBL_MAX_10_EXP):
2581 * print.c (DBL_DIG):
2582 Remove. C89 or later always defines these.
2583 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
2584 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
2585 (arith_error, domain_error, domain_error2):
2586 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
2587 no longer needed -- we simply return what C returns. All uses removed.
2588 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
2590 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
2591 Remove. All uses expanded, as these macros are no longer used
2592 more than once and are now more trouble than they're worth.
2593 (Ftan): Use tan, not sin / cos.
2594 (Flogb): Assume C89 frexp.
2595 (fmod_float): Assume C89 fmod.
2596 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
2597 (init_floatfns): Remove. All uses removed.
2599 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
2601 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
2602 compositeToPoint for OSX < 10.6 (Bug#12390).
2604 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
2606 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
2607 This produces more-accurate results.
2609 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
2611 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
2612 changes (Bug#12088).
2614 2012-09-08 Chong Yidong <cyd@gnu.org>
2616 * syntax.c (Fstring_to_syntax): Doc fix.
2618 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
2620 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
2621 in the internal border.
2622 (x_set_window_size): Remove static variables and their usage.
2623 (ns_redraw_scroll_bars): Fix NSTRACE arg.
2624 (ns_after_update_window_line, ns_draw_fringe_bitmap):
2625 Remove fringe/internal border adjustment (Bug#11052).
2626 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
2627 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
2628 (ns_fix_rect_ibw): Remove.
2629 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
2630 (ns_dumpglyphs_box_or_relief): Ditto.
2631 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
2633 (ns_dumpglyphs_image): Ditto.
2634 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
2636 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
2637 their usage. Add fringe_extended_p and its use as in other terms.
2638 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
2639 scroll bar was removed.
2640 (updateFrameSize): New function.
2641 (windowDidResize): Move code to updateFrameSize and call it.
2643 * nsterm.h (EmacsView): Add updateFrameSize.
2645 2012-09-07 Chong Yidong <cyd@gnu.org>
2647 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
2649 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
2651 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
2653 More signal-handler cleanup (Bug#12327).
2654 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
2655 Problem introduced when merging patches. Noted by Eli Zaretskii in
2656 <http://bugs.gnu.org/12327#67>.
2657 * floatfns.c: Comment fix.
2658 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
2659 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
2660 and anyway the declaration is harmless even if SIGDANGER is not defined.
2661 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
2662 defined BROKEN_FIONREAD). systty.h formerly did this, but other
2663 source files not surprisingly expected syssignal.h to define, or
2664 not define, SIGIO, and it's cleaner to do it that way, for consistency.
2665 Include <sys/ioctl.h>, for FIONREAD.
2666 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
2667 This eliminates a problem whereby other files mysteriously had
2668 to include "syssignal.h" before including "systty.h" if they
2669 wanted to use "#ifdef SIGIO".
2671 2012-09-07 Eli Zaretskii <eliz@gnu.org>
2673 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
2675 * w32.c (sigemptyset): Empty the set.
2676 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
2678 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
2680 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
2682 * alloc.c (mark_buffer): Revert unsafe marking optimization.
2683 (mark_object): Likewise for frame objects.
2685 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
2687 * syssignal.h (handle_on_main_thread): Always declare,
2688 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
2689 This ports to platforms without HAVE_PTHREAD.
2691 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
2693 Signal-handler cleanup (Bug#12327).
2694 Emacs's signal handlers were written in the old 4.2BSD style with
2695 sigblock and sigmask and so forth, and this led to some
2696 inefficiencies and confusion. Rewrite these to use
2697 pthread_sigmask etc. without copying signal sets around. Also,
2698 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
2699 'signal', and instead use functions that do not attempt to take
2700 over the system name space. This patch causes Emacs's text
2701 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
2702 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
2703 Do not include <signal.h> or "syssignal.h", as these
2704 modules do not use signals.
2705 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
2706 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
2707 Do not include <signal.h>, as "syssignal.h" does that for us now.
2708 * atimer.c (sigmask_atimers): New function.
2709 (block_atimers, unblock_atimers): New functions,
2710 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
2712 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
2713 no longer needed here.
2714 * emacs.c (main): Inspect existing signal handler with sigaction,
2715 so that there's no need to block and unblock SIGHUP.
2716 * sysdep.c (struct save_signal): New member 'action', replacing
2717 old member 'handler'.
2718 (save_signal_handlers, restore_signal_handlers):
2719 Use sigaction instead of 'signal' to save and restore.
2720 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
2721 New function. All users of 'signal' modified to use set_sighandler
2722 if they're writeonly, and to use sys_signal if they're read+write.
2723 (emacs_sigaction_init, forwarded_signal): New functions.
2724 (sys_signal): Remove. All uses replaced by calls to sigaction
2725 and emacs_sigaction_init, or by direct calls to 'signal'.
2726 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
2727 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
2728 all uses replaced by pthread_sigmask etc. calls.
2729 * syssignal.h: Include <signal.h>.
2730 (emacs_sigaction_init, forwarded_signal): New decls.
2731 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
2732 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
2733 (sigmask, sys_sigmask): Remove; no longer needed.
2734 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
2735 (sigblock, sigunblock, sigfree):
2736 (sigsetmask) [!defined sigsetmask]:
2737 Remove. All uses replaced by pthread_sigmask.
2738 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
2739 no longer need to be replaced, and its typical old uses
2740 are now done via emacs_sigaction_init and sigaction.
2741 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
2742 (sys_sigdel): Remove; unused.
2743 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
2745 2012-09-06 Eli Zaretskii <eliz@gnu.org>
2747 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
2748 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
2750 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
2752 Explicitly mark buffer_defaults and buffer_local_symbols.
2753 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
2754 mark_local_symbols here.
2755 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
2756 since special buffers aren't marked here any more.
2757 (allocate_buffer): Chain new buffer with all_buffers here...
2758 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
2760 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
2761 (syms_of_buffer): Remove staticpro of the above.
2762 (init_buffer_once): Set names for buffer_defaults and
2763 buffer_local_symbols.
2765 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
2767 Use bool for booleans in font-related modules.
2768 * font.c (font_intern_prop, font_style_to_value)
2769 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
2770 (generate_otf_features, font_check_otf_features, font_check_otf)
2771 (font_match_p, font_list_entities, font_at):
2772 * fontset.c (fontset_id_valid_p, reorder_font_vector
2773 (fontset_find_font, Fset_fontset_font)
2774 (face_suitable_for_char_p) [0]:
2775 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
2776 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
2777 (m17n_flt_initialized, ftfont_shape_by_flt):

2779 * nsfont.m (nsfont_draw):
2780 * w32font.c (w32font_draw):
2781 * w32term.c (x_draw_glyphless_glyph_string_foreground):
2782 Use bool for booleans.
2783 * font.h: Adjust to above API changes.
2784 (struct font, struct font_driver, struct font_driver_list):
2785 Use bool for booleans.
2786 (struct font): Remove useless member encoding_type.
2788 * fontset.c, xftfont.c: Omit unnecessary static decls.
2790 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
2792 * alloc.c (mark_object): Revert window marking code
2793 since it's unsafe for the Fset_window_configuration.
2795 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
2797 Fix race conditions with signal handlers and errno (Bug#12327).
2798 Be more systematic about preserving errno whenever a signal
2799 handler returns, even if it's not in the main thread. Do this by
2800 renaming signal handlers to distinguish between signal delivery
2801 and signal handling. All uses changed.
2802 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
2803 * data.c (deliver_arith_signal): Rename from arith_error.
2804 * dispnew.c (deliver_window_change_signal): Rename from
2805 window_change_signal.
2806 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
2807 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
2808 * keyboard.c (deliver_input_available_signal): Rename from
2809 input_available_signal.
2810 (deliver_user_signal): Rename from handle_user_signal.
2811 (deliver_interrupt_signal): Rename from interrupt_signal.
2812 * process.c (deliver_pipe_signal): Rename from send_process_trap.
2813 (deliver_child_signal): Rename from sigchld_handler.
2814 * atimer.c (handle_alarm_signal):
2815 * data.c (handle_arith_signal):
2816 * dispnew.c (handle_window_change_signal):
2817 * emacs.c (handle_fatal_signal, handle_danger_signal):
2818 * keyboard.c (handle_input_available_signal):
2819 * keyboard.c (handle_user_signal, handle_interrupt_signal):
2820 * process.c (handle_pipe_signal, handle_child_signal):
2821 New functions, with the actual signal-handling code taken from the
2822 original respective signal handlers, sans the sporadic attempts to
2823 preserve errno, since that's now done by handle_on_main_thread.
2824 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
2825 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
2826 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
2828 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
2829 Move initialization of main_thread to sysdep.c's init_signals.
2830 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
2831 our usage, and simplifies the mainline code.
2832 (record_child_status_change): New static function, as a helper
2833 for handle_child_signal, and with most of the old child handler's
2835 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
2836 (handle_child_signal): Use the above.
2837 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
2838 Moved here from emacs.c.
2839 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
2840 code moved here from emacs.c's main function.
2841 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
2842 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
2843 This lets callers save and restore errno properly.
2845 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
2847 Remove redundant or unused things here and there.
2848 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
2849 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
2850 * editfns.c (Fcompare_buffer_substrings): Likewise.
2851 * frame.h (struct terminal, struct font_driver_list):
2852 Remove redundant declarations.
2853 * window.h (Qleft, Qright): Likewise.
2855 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
2857 Do not mark objects from deleted buffers, windows and frames.
2858 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
2859 (mark_object): Likewise for windows and frames.
2861 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
2863 * alloc.c (valid_lisp_object_p): Treat killed buffers,
2864 buffer_defaults and buffer_local_symbols as valid objects.
2865 Return special value to denote them.
2867 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
2869 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
2870 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
2871 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
2872 (file_name_absolute_p, Fsubstitute_in_file_name):
2873 (check_executable, check_writable, Ffile_accessible_directory_p)
2874 (Fset_file_selinux_context, Fdefault_file_modes)
2875 (Finsert_file_contents, choose_write_coding_system)
2876 (Fwrite_region, build_annotations, a_write, e_write)
2878 * filelock.c (boot_time_initialized, get_boot_time)
2879 (get_boot_time_1, lock_file_1, within_one_second):
2880 * floatfns.c (in_float):
2881 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
2882 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
2883 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
2884 * lisp.h (struct Lisp_Hash_Table.cmpfn):
2885 * window.c (compare_window_configurations):
2886 Use bool for booleans.
2887 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
2888 (Fdefault_file_modes): Now mode_t, not int, for modes.
2889 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
2890 (internal_delete_file): Now returns void, not a (boolean) int,
2891 since nobody was looking at the return value.
2892 * lisp.h, window.h: Adjust to above API changes.
2894 * xdisp.c (set_message): Simplify and reindent last change.
2896 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
2898 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
2900 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
2902 * eval.c (call_debugger): Make the function non-static so that we
2903 can call it from set_message.
2905 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
2906 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
2908 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
2910 Give more-useful info on a fatal error (Bug#12328).
2911 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
2912 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
2913 of doing the work ourselves.
2914 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
2915 do most of the work.
2916 (fatal_error_backtrace): New function, taken from the guts
2917 of the old fatal_error_signal, but with a new option to output
2919 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
2920 info about the signal than just its number.
2921 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
2922 * sysdep.c: Include <execinfo.h>
2923 (emacs_backtrace): New function, taken partly from the previous
2924 code of the 'die' function.
2925 (emacs_abort): Call fatal_error_backtrace rather than abort.
2927 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
2929 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
2930 eager (load-time) macro-expansion.
2931 * lisp.mk (lisp): Add macroexp.
2933 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
2935 Simplify redefinition of 'abort' (Bug#12316).
2936 Do not try to redefine the 'abort' function. Instead, redo
2937 the code so that it calls 'emacs_abort' rather than 'abort'.
2938 This removes the need for the NO_ABORT configure-time macro
2939 and makes it easier to change the abort code to do a backtrace.
2940 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
2941 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
2942 Remove; sysdep.c's emacs_abort now takes its place.
2943 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
2944 'abort' changed to use 'emacs_abort'.
2945 * msdos.c (dos_abort) [defined abort]: Remove; not used.
2946 (abort) [!defined abort]: Rename to ...
2947 (emacs_abort): ... new name.
2948 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
2949 the place of the old 'abort' in emacs.c.
2950 * w32.c, w32fns.c (abort): Do not #undef.
2951 * w32.c (emacs_abort): Rename from w32_abort.
2953 2012-09-04 Eli Zaretskii <eliz@gnu.org>
2955 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
2956 offsets[j].dv, since the y axis of the screen coordinates points
2957 down, while the y axis of the font definition coordinates points
2958 up. This fixes display of Arabic diacritics such as KASRA and
2959 KASRATAN. (Bug#11860)
2961 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
2963 Be more systematic about _setjmp vs setjmp.
2964 * alloc.c (test_setjmp, mark_stack):
2965 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
2966 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
2967 (png_load, my_error_exit, jpeg_load):
2968 * process.c (send_process_trap, send_process):
2969 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
2970 The underscored versions are up to 30x faster on some hosts.
2971 Formerly, the code used setjmp+longjmp sometimes and
2972 _setjmp+_longjmp at other times, with no particular reason to
2973 prefer setjmp+longjmp.
2975 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
2977 Fix minor problem found by static checking.
2978 * buffer.c (Fdelete_all_overlays): Return nil.
2980 2012-09-03 Martin Rudalics <rudalics@gmx.at>
2982 * buffer.c (Fdelete_all_overlays): New function.
2984 2012-09-03 Chong Yidong <cyd@gnu.org>
2986 * gtkutil.c: Add extern decl for Qxft.
2988 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
2990 * emacs.c, eval.c: Use bool for boolean.
2991 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
2992 (malloc_using_checking) [DOUG_LEA_MALLOC]:
2993 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
2994 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
2995 (main, decode_env_path, Fdaemon_initialized):
2996 * eval.c (call_debugger, Finteractive_p, interactive_p):
2997 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
2998 (maybe_call_debugger, Fbacktrace):
2999 * process.c (read_process_output, exec_sentinel):
3000 Use bool for booleans.
3001 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
3002 All callers changed.
3003 * eval.c (interactive_p): Omit always-true boolean argument
3004 EXCLUDE_SUBRS_P. All callers changed.
3005 * dispextern.h, lisp.h: Reflect above API changes.
3006 * firstfile.c (dummy): Use the address of 'main', whose signature
3007 won't change, instead of the address of 'initialize', whose
3008 signature just changed from int to bool.
3009 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
3010 * msdos.c (fatal_error_in_progress): ... from here.
3011 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
3013 (redisplay_internal, unwind_redisplay): Simply clear
3014 REDISPLAYING_P when unwinding, instead of saving its previous,
3015 always-false value and then restoring it.
3017 Clean up some extern decls.
3018 Mostly, this hoists extern decls out of .c files and into .h files.
3019 That way, we're more likely to catch errors if the interfaces change.
3020 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
3021 declare xg_mark_data.
3022 * dispextern.h (x_frame_parm_handlers):
3024 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
3025 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
3026 (Qultra_bold, Qoblique, Qitalic):
3027 Move extern decl here from .c file.
3028 * alloc.c (xg_mark_data) [USE_GTK]:
3030 * eval.c (Qlexical_binding):
3031 * fns.c (time) [!HAVE_UNISTD_H]:
3032 * gtkutil.c (Qxft, Qnormal, Qextra_light, Qlight, Qsemi_light)
3033 (Qsemi_bold, Qbold, Qextra_bold, Qultra_bold, Qoblique, Qitalic):

3035 * lread.c (Qinternal_interpreter_environment):
3036 * minibuf.c (Qbuffer):
3037 * process.c (QCfamily, QCfilter):
3038 * widget.c (free_frame_faces):
3039 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
3040 * xfont.c (x_clear_errors):
3041 * xterm.c (x_frame_parm_handlers):
3042 Remove now-redundant extern decls.
3043 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
3044 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
3046 * xfaces.c: Remove unnecessary static decls.
3047 * xterm.c (updating_frame): Remove decl of nonexistent object.
3049 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
3050 when building globals.h, as the objects that are not built on
3051 this host are not needed to compile C files on this host.
3053 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
3055 * gtkutil.h: Remove prototype for x_wm_set_size_hint.
3057 * frame.h: Add missing prototype for x_wm_set_size_hint.
3059 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>

3063 (Fdocumentation, Fdocumentation_property, Fsnarf_documentation)
3064 (Fsubstitute_command_keys):

3066 (save_excursion_save, save_excursion_restore)
3067 (disassemble_lisp_time, decode_time_components, emacs_nmemftime)
3068 (format_time_string, general_insert_function)
3069 (make_buffer_string, make_buffer_string_both)
3070 (Fsubst_char_in_region, Ftranslate_region_internal, Fformat):
3071 * insdel.c (check_markers, gap_left, adjust_markers_for_insert)

3093 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
3095 * makefile.w32-in (CCL_H, W32FONT_H): New macros.
3096 (ATIMER_H, FONT_H, $(BLD)/alloc.$(O), $(BLD)/callproc.$(O))

3101 ($(BLD)/w32font.$(O), $(BLD)/w32uniscribe.$(O)): Update dependencies.
3103 2012-09-01 Eli Zaretskii <eliz@gnu.org>
3105 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
3106 more than one grapheme cluster passed to the shaper: compute the
3107 offset adjustment values separately for each cluster. (Bug#11860)
3109 * image.c: Restore mistakenly removed inclusion of w32.h. Without
3110 it, GCC doesn't see prototypes of w32_delayed_load, and complains
3111 about implicit conversions from integer to pointer.
3113 2012-09-01 Daniel Colascione <dancol@dancol.org>
3115 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
3116 system used too early.
3118 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
3120 Better seed support for (random).
3121 * emacs.c (main): Call init_random.
3122 * fns.c (Frandom): Set the seed from a string argument, if given.
3123 Remove long-obsolete Gentzel cruft.

3130 Remove x_set_frame_alpha, x_bitmap_icon, x_make_frame_visible,
3131 x_make_frame_invisible, x_iconify_frame, x_free_frame_resources,

3133 x_set_menu_bar_lines, x_char_width, x_char_height, x_sync,
3134 x_set_tool_bar_lines, x_activate_menubar, and free_frame_menubar,
3135 all of which have been moved to common code.
3137 * xfaces.c: Include TERM_HEADER instead of listing all possible
3138 window-system headers.
3140 * w32xfns.c (x_sync): Correct definition of x_sync (a no-op here)

3144 directly accessing frame internals.
3146 * w32font.h: Include font.h. Define syms_of_w32font and
3149 * process.c: Include TERM_HEADER instead of listing all possible
3150 window-system headers.
3152 * nsterm.h: Remove declarations now in frame.h.
3153 Define FRAME_X_SCREEN, FRAME_X_VISUAL.
3155 * menu.c: Include TERM_HEADER instead of listing all possible
3156 window-system headers.
3158 * keyboard.h: Declare ignore_mouse_drag_p whenever we have a
3161 * keyboard.c: Include TERM_HEADER instead of listing all possible
3162 window-system headers.
3164 * image.c: Include TERM_HEADER instead of listing all possible
3165 window-system headers. Declare Vlibrary_cache when compiling for
3168 * gtkutil.h (xg_list_node_): Include xterm.h to pick up needed
3169 window system declarations.
3171 * frame.h: Move common functions here: set_frame_menubar,
3172 x_set_window_size, x_sync, x_get_focus_frame,
3173 x_set_mouse_position, x_set_mouse_pixel_position,
3174 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,
3175 x_char_width, x_char_height, x_pixel_width, x_pixel_height,

3194 * Makefile.in: Define WINDOW_SYSTEM_OBJ to hold objects needed for
3195 the current window system; include in list of objects to link into
3198 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
3200 Remove mark_ttys function and fix tty_display_info initialization.
3201 * lisp.h (mark_ttys): Remove prototype.
3202 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
3203 to mark_ttys because all possible values of 'top_frame' slot are
3204 the frames which are reachable from Vframe_list.
3205 * term.c (mark_ttys): Remove.
3206 (init_tty): Safely initialize 'top_frame' slot with Qnil.
3208 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
3210 Change struct frame bitfields from unsigned char to unsigned.
3211 * frame.h (struct frame): Change type of 'display_preempted',
3212 'visible', 'iconified', 'has_minibuffer', 'wants_modeline',
3213 'auto_raise', 'auto_lower', 'no_split', 'explicit_name',
3214 'window_sizes_changed', 'mouse_moved' and 'pointer_invisible'
3215 bitfields from unsigned char to unsigned.
3217 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
3219 Remove unused member of struct x_output and struct w32_output.
3220 * xterm.h (struct x_output): Remove unused field 'needs_exposure'.
3221 * w32term.h (struct w32_output): Likewise.
3223 2012-08-30 Jan Djärv <jan.h.d@swipnet.se>
3225 * gtkutil.c (x_wm_set_size_hint): Use 1 col for base_width so it
3226 does not become zero (Bug#12234).
3228 2012-08-30 Paul Eggert <eggert@cs.ucla.edu>
3230 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
3231 for GCC 4.7.1 x86-64.
3233 2012-08-30 Glenn Morris <rgm@gnu.org>
3235 * lread.c (init_lread): For out-of-tree builds, only add the
3236 source directory's site-lisp dir to the load-path if it exists,
3237 consistent with in-tree builds. (Bug#12302)
3239 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>
3241 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize
3242 button_values to NULL. Call setStykeMask so dialogs get a close button.
3243 (windowShouldClose:): Set window_closed.
3244 (dealloc): New member, free button_values.
3245 (process_dialog:): Make member function. Remove window argument,
3246 replace window with self. Count buttons and allocate and store values
3248 (addButton:value:row:): value is int with the name tag. Call setTag
3249 with tag. Remove return self, declare return value as void.
3250 (addString:row:): Remove return self, declare return value as void.
3251 (addSplit): Remove return self, declare return value as void.
3252 (clicked:): Remove return self, declare return value as void.
3253 Set dialog_return to button_values[seltag]. Code formatting change.
3254 (initFromContents:isQuestion:): Adjust call to process_dialog.
3255 Code formatting change.
3256 (timeout_handler:): Set timer_fired to YES.
3257 (runDialogAt:): Set timer_fired to NO.
3258 Handle click on close button as quit.
3260 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
3261 Add window_closed and button_values. Add void as return value for
3262 add(Button|String|Split). addButton takes int instead of Lisp_Object.
3263 Add process_dialog as new member.
3265 2012-08-28 Eli Zaretskii <eliz@gnu.org>
3267 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it
3268 is not one of the heaps we manage. (Bug#12242)
3270 2012-08-28 Glenn Morris <rgm@gnu.org>
3272 * eval.c (Fcalled_interactively_p): Doc fix. (Bug#11747)
3274 2012-08-28 Martin Rudalics <rudalics@gmx.at>
3276 * window.c (Fset_window_configuration): Remove handling of
3277 auto-buffer-name window parameter. Install revision of reverted

3283 * buffer.c (Fset_buffer_major_mode): Signal an error
3284 if the buffer is dead.
3285 (Fother_buffer, other_buffer_safely): Remove redundant
3288 2012-08-28 Dmitry Antipov <dmantipov@yandex.ru>
3290 Always use set_buffer_if_live to restore original buffer at unwind.
3291 * buffer.h (record_unwind_current_buffer): New function.
3292 * bytecode.c, dispnew.c, editfns.c, fileio.c, fns.c, insdel.c:

3294 * undo.c, window.c: Adjust users.
3295 * buffer.c (set_buffer_if_live): Fix comment.
3297 2012-08-28 Dmitry Antipov <dmantipov@yandex.ru>
3299 Fix usage of set_buffer_internal.
3300 * buffer.h (set_buffer_internal): Make it BUFFER_INLINE.
3301 * buffer.c (set_buffer_if_live): Use set_buffer_internal.
3302 * coding.c (decode_coding): Omit redundant test.
3303 * fileio.c (decide_coding_unwind): Likewise.
3304 * fns.c (secure_hash): Likewise.

3306 * keyboard.c (command_loop_1): Likewise.
3307 * print.c (PRINTFINISH): Likewise.
3308 * xdisp.c (run_window_scroll_functions): Use set_buffer_internal.
3310 2012-08-27 Paul Eggert <eggert@cs.ucla.edu>

3328 (change_frame_size_1, sit_for):
3329 Use bool for boolean.
3330 (clear_glyph_matrix_rows): Rename from enable_glyph_matrix_rows,
3331 and remove last int (actually boolean) argument, which was always 0.
3332 All callers changed.
3333 * dispextern.h, frame.h, lisp.h: Reflect above API changes.
3334 * dispextern.h (struct composition_it): Use bool for boolean.
3335 (struct glyph_matrix): Don't assume buffer sizes can fit in 'int'.
3336 (struct bidi_it): Use unsigned:1, not int, for boolean prev_was_pdf.
3337 * dired.c (file_name_completion):
3338 Use bool for boolean. (This was missed in an earlier change.)
3340 2012-08-27 Martin Rudalics <rudalics@gmx.at>
3342 * window.c (Fset_window_configuration): Revert first part of
3345 2012-08-27 Jan Djärv <jan.h.d@swipnet.se>
3347 * nsterm.h (NSPanel): New class variable dialog_return.
3349 * nsmenu.m (initWithContentRect:styleMask:backing:defer:):
3350 Initialize dialog_return.
3351 (windowShouldClose:): Use stop instead of stopModalWithCode.
3352 (clicked:): Ditto, and also set dialog_return (Bug#12258).
3353 (timeout_handler:): Use stop instead of abortModal. Send a dummy
3355 (runDialogAt:): Make ret Lisp_Object. Set it from dialog_return when

3370 Use bool for booleans.
3371 * dired.c (file_name_completion):
3372 * process.h (fd_callback):
3373 Omit int (actually boolean) argument. It wasn't being used.
3375 * composite.h, lisp.h: Reflect above API changes.

3399 * fileio.c (Finsert_file_contents):
3400 Use bool for booleans.
3401 * coding.h, lisp.h: Reflect above API changes.
3402 * coding.c: Remove unnecessary static function decls.
3403 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
3404 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
3405 not a boolean 'int', since callers never look at the return value.
3406 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
3407 * coding.h (decoding_buffer_size, encoding_buffer_size)
3408 (emacs_mule_string_char): Remove unused extern decls.
3409 (struct iso_2022_spec, struct coding_system):

3412 All initializations removed.
3413 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
3415 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
3417 Fix spare memory change (Bug#12286).
3418 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
3419 (valid_lisp_object_p): Likewise.
3421 2012-08-27 Martin Rudalics <rudalics@gmx.at>
3423 * window.c (Fset_window_configuration): Record any window's old
3424 buffer if it's replaced (see Bug#8789). If the new current
3425 buffer doesn't appear in the selected window, go to its old
3428 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
3430 Special MEM_TYPE_SPARE to denote reserved memory.
3431 * alloc.c (enum mem_type): New memory type.
3432 (refill_memory_reserve): Use new type for spare memory.
3433 This prevents live_cons_p and live_string_p from incorrect
3434 detection of uninitialized objects from spare memory as live.
3436 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
3439 * Makefile.in (.PHONY): versioclean -> versionclean.
3441 Remove unused external symbols.
3442 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
3443 * window.c (Qwindow_valid_p, decode_valid_window):
3444 Now static, not extern.
3445 * data.c (Qinterval): Remove; unused.
3446 (syms_of_data): Do not define 'interval'.
3447 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
3448 * window.h (decode_valid_window):
3451 * character.c, charset.c, chartab.c: Use bool for booleans.

3461 (char_table_set_range, optimize_sub_char_table)
3462 (map_sub_char_table):
3463 Use bool for boolean.
3464 * character.c (str_to_unibyte): Omit last boolean argument; it was
3465 always 0. All callers changed.
3466 * character.h, charset.h: Adjust to match previous changes.
3467 * character.h (char_printable_p): Remove decl of nonexistent function.
3468 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
3469 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
3470 are all boolean, so make them single-bit bitfields.
3472 * lisp.h (ASET): Remove attempt to detect side effects.
3473 It was meant to be temporary and it often doesn't work,
3474 because when IDX has side effects the behavior of IDX==IDX
3475 is undefined. See Stefan Monnier in
3476 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
3478 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
3480 * lisp.h (functionp): New function (extracted from Ffunctionp).
3481 (FUNCTIONP): Use it.
3482 * eval.c (Ffunctionp): Use it.
3484 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
3486 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
3487 as that's faster and simpler than static storage. Don't bother
3488 with the g_main_context_query overhead if g_main_context_pending
3489 says no events are pending.
3490 (gfds, gfds_size): Remove these static vars.
3491 (xgselect_initialize): Remove; no longer needed.
3492 All uses and decls removed.
3494 * emacs.c (fatal_error_signal_hook): Remove.
3495 All uses removed. This leftover from old code was always 0.
3497 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
3498 * casefiddle.c (casify_object, casify_region):
3499 * casetab.c (set_case_table):
3500 * category.c, category.h (word_boundary_p):
3501 * category.h (CHAR_HAS_CATEGORY):
3502 Use bool for booleans, instead of int.
3504 2012-08-25 Eli Zaretskii <eliz@gnu.org>
3506 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
3508 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
3510 On assertion failure, print backtrace if available.
3511 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
3512 (die) [ENABLE_CHECKING]: Print a backtrace if available.
3513 * Makefile.in (LIB_EXECINFO): New macro.
3516 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
3517 * bytecode.c (exec_byte_code):
3518 * callint.c (check_mark, Fcall_interactively):
3519 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
3520 (getenv_internal, sync_process_alive, call_process_exited):
3521 * lisp.h (USE_SAFE_ALLOCA):
3522 Use bool for booleans, instead of int.
3523 * lisp.h, process.h: Adjust prototypes to match above changes.
3524 * callint.c (Fcall_interactively): Don't assume the mark's
3525 offset fits in 'int'.
3527 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
3529 * buffer.c, buffer.h: Use bool for boolean.
3530 * buffer.c (reset_buffer_local_variables)

3536 (mmap_enlarge, mmap_set_vars):
3537 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
3538 Use bool for booleans, instead of int.
3539 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
3540 since the 1-or-0 return value is always ignored anyway.
3541 (mmap_initialized_p):
3542 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
3543 * buffer.h, lisp.h: Adjust prototypes to match above changes.
3545 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
3547 * bidi.c: Use bool for boolean.
3548 This is a bit more readable, and makes the text segment of bidi.o
3549 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
3550 Presumably it's faster too.
3551 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):

3556 (bidi_explicit_dir_char, bidi_level_of_next_char)
3557 (bidi_find_other_level_edge, bidi_move_to_visually_next):
3558 Use bool for booleans, instead of int.
3559 * dispextern.h (bidi_init_it, bidi_paragraph_init)
3560 (bidi_unshelve_cache): Adjust decls to match code.
3562 2012-08-23 Martin Rudalics <rudalics@gmx.at>
3564 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
3567 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
3569 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
3570 * atimer.h: Include <stdbool.h>.
3572 2012-08-22 Dan Nicolaescu <dann@gnu.org>
3574 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
3575 compile time tests instead of run time tests on systems that do
3577 (FRAME_MAC_P): Remove leftover from deleted code.
3578 * frame.c (syms_of_frame): Remove leftover from deleted code.
3580 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
3582 * nsterm.m (insertText:): Don't clear modifiers if code is space.
3584 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
3586 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
3587 Otherwise, the compiler complains about (A?B:C) where B is void
3588 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
3589 (fontset_add): Return void, for FONTSET_ADD.
3591 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
3593 * alloc.c: Use bool for booleans.
3594 (gc_in_progress, abort_on_gc)
3595 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
3596 (dont_register_blocks) [GC_MALLOC_CHECK]:
3597 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.

3599 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
3600 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
3601 (mark_stack, valid_pointer_p, make_pure_string)
3602 (Fgarbage_collect, survives_gc_p, gc_sweep):
3603 Use bool for booleans, instead of int.
3604 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
3605 Remove unused local.
3606 * alloc.c (PURE_POINTER_P):
3607 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
3608 * editfns.c (Fformat):
3609 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
3611 * fns.c (sweep_weak_table):
3612 * lisp.h (suppress_checking, push_message, survives_gc_p)
3613 (make_pure_string, gc_in_progress, abort_on_gc):
3614 * lread.c (readchar, read1):
3615 * print.c (Fprin1_to_string):
3616 * xdisp.c (push_message):
3617 Use bool for booleans affected directly or indirectly by
3620 Make recently-introduced setters macros.
3621 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
3622 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
3623 (set_fontset_default, set_fontset_fallback): Rename from their
3624 upper-case counterparts, and make them functions rather than macros.
3625 This is more consistent with the other recently-introduced setters.
3626 These don't need to be inline, since they're local.
3628 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
3630 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
3631 the loop (Bug#12247).
3633 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
3635 * lisp.h (vcopy): Use memcpy rather than our own loop.
3636 This fixes a performance regression introduced by the recent
3637 addition of vcopy. This means 'vcopy' will need to be modified
3638 for a copying collector, but that's OK. Also, tighten the
3639 checking in the assertion.
3641 2012-08-21 Eli Zaretskii <eliz@gnu.org>
3643 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
3644 components for RTL text (Bug#11860). Adjust X-OFFSET of each
3645 non-base glyph for the width of the base character, according to
3646 what x_draw_composite_glyph_string_foreground expects.
3647 Generate WADJUST value according to composition_gstring_width's
3648 expectations, to produce correct width of the composed character.
3649 Reverse the sign of the DU offset produced by ScriptPlace.
3651 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
3653 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
3655 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>

3735 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>

3738 as gnulib does this if the system doesn't.
3739 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:

4610 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
4611 * w32.c (init_environment): Change the default values of many
4612 environment variables in dflt_envvars[] to NULL, to avoid pushing
4613 them into environment when they were not already defined.
4614 Remove the code that deletes site-lisp subdirectories from the default
4615 value of EMACSLOADPATH, as it is no longer needed.
4616 (check_windows_init_file): Now external, not static.
4617 Use Vload_path as is, without adding anything, as this function is now
4618 called when Vload_path is already set up.
4620 * w32.h (check_windows_init_file): Add prototype.
4622 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build
4623 directory, ignore the /*/i386/ tail in Vinvocation_directory, for
4624 compatibility with Posix platforms.
4625 (main): Move the call to check_windows_init_file to here from

4629 installation tree, as appropriate.
4631 * callproc.c (init_callproc_1): Call decode_env_path instead of
4632 doing its equivalent by hand.
4633 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
4634 the code that sets Vexec_path run on MS-Windows.
4636 * lread.c (init_lread): Add comments to #ifdef's.
4638 * msdos.c (dos_set_window_size, IT_update_begin)

4646 Now constants, not macros.
4648 2012-08-03 Paul Eggert <eggert@cs.ucla.edu>
4650 Remove unnecessary casts involving pointers.
4651 These casts are no longer needed now that we assume C89 or later,
4652 since they involve casting to or from void *.

4654 (make_pure_float, make_pure_vector):
4655 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP):

4665 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
4666 Remove unnecessary pointer casts.
4667 * alloc.c (record_xmalloc): New function.
4668 * lisp.h (record_xmalloc): New decl.
4669 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
4670 more like a function. This is because the pointer cast is not
4671 needed. All uses changed.
4672 * print.c (print_string, print_error_message): Avoid length recalc.
4674 Improve fix for macroexp crash with debugging (Bug#12118).
4675 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
4676 ARRAY_MARK_FLAG when checking subscripts, because ASET is
4677 not supposed to be invoked from the garbage collector.
4678 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
4679 (gc_aset): New function, which is like ASET but can be
4680 used in the garbage collector.
4681 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)

4696 headers (most versions of MinGW w32api don't).
4697 (get_security_info, create_symbolic_link)
4698 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
4700 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
4701 in the argument file name.

4704 (sys_rename): Diagnose renaming of a symlink when the user doesn't
4705 have the required privileges.
4706 (get_file_security_desc_by_name): Rename from
4707 get_file_security_desc.

4709 with addition of handling of symlinks and support for 'lstat'.
4710 If possible, get file's attributes and security information by
4711 handle, not by name. Produce S_IFLNK bit for symlinks, when
4712 called from 'lstat'.
4713 (stat, lstat): New functions, call 'stat_worker'.
4714 (symlink, readlink, careadlinkat): Rewritten to create and resolve
4715 symlinks when the underlying filesystem supports them.
4717 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
4719 Fix macroexp crash on Windows with debugging (Bug#12118).
4720 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
4721 checking subscripts; problem introduced with the recent
4722 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
4723 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
4724 since it's used in non-static inline functions now.
4726 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
4727 Don't assume buffer size fits in 'int'. Remove unused local.

4745 * character.c (CHARACTER_INLINE):
4746 * charset.c (CHARSET_INLINE):
4747 * composite.c (COMPOSITE_INLINE):
4748 * dispnew.c (DISPEXTERN_INLINE):
4749 * sysdep.c (SYSTIME_INLINE):
4750 Define to EXTERN_INLINE, so that the corresponding functions
4751 are compiled into code.
4752 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
4753 (INLINE_HEADER_END): New macros.
4754 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

4776 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
4778 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
4779 This how ASET and AREF are supposed to work, and makes
4780 it easier to think about future improvements. See
4781 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
4782 * charset.h (set_charset_attr): New function.

5035 * s/aix4-2.h (sigmask): No need to undefine it, since syssignal.h
5036 does that unconditionally. Remove file, which is now empty.
5038 * s/freebsd.h, s/gnu-linux.h, s/sol2-6.h, s/unixware.h:
5041 2012-07-30 Paul Eggert <eggert@cs.ucla.edu>

5159 * w32inevt.c: Include w32inevt.h.
5160 (w32_read_console_input): New inline function, calls either
5161 ReadConsoleInputA or ReadConsoleInputW, depending on the value of
5162 w32_console_unicode_input.
5163 (fill_queue): Call w32_read_console_input instead of ReadConsoleInput.
5164 (w32_kbd_patch_key, key_event): Use the codepage returned by
5165 GetConsoleCP, rather than the ANSI codepage returned by GetLocaleInfo.
5166 (key_event): use uChar.UnicodeChar only if
5167 w32_console_unicode_input is non-zero.

5194 * alloc.c (listn): Fix the order the arguments are consed onto the
5197 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
5198 enumeration constants, as PURE and HEAP are too general, and clash
5199 with other headers and sources, such as gmalloc.c and the
5200 MS-Windows system headers. All users changed.
5202 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
5204 Revert last save_excursion_save and save_excursion_restore changes.
5205 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

5215 2012-07-27 Paul Eggert <eggert@cs.ucla.edu>
5217 Improve GDB symbol export (Bug#12036).
5218 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
5219 arms of an 'if', not using conditional expressions; otherwise GDB
5220 complains about the types in the unevaluated arm when the argument
5221 is an integer literal.
5222 (xgetint): Simplify expression.
5223 * alloc.c (gdb_make_enums_visible): New constant. This ports to
5224 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
5225 Zaretskii in <http://bugs.gnu.org/12036#13>.
5226 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
5227 needed now that we have gdb_make_enums_visible.
5228 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
5229 (enum enum_USE_LSB_TAG):
5230 New enum types, packaging up enums that need to be exported to GDB.

5248 * xdisp.c (syms_of_xdisp): Likewise.
5249 * xfns.c (syms_of_xfns): Likewise.
5251 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
5253 Fast save_excursion_save and save_excursion_restore.
5254 * lisp.h (struct Lisp_Excursion): New data type.
5255 (PVEC_EXCURSION): New pseudovector type.
5256 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
5257 to deal with it. Adjust comments.
5258 (init_marker, attach_marker): New prototype.
5259 (unchain_marker): Adjust prototype.

5268 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
5270 Fix export of symbols to GDB (Bug#12036).
5271 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
5272 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
5273 emacs.c, as this is a more-suitable home. Had this been done earlier
5274 the fix for 12036 would have avoided some of the problems noted in
5275 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
5276 would have been more obvious.
5277 * emacs.c: Do not include <verify.h>; no longer needed.
5278 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
5279 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
5280 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
5281 Remove; now done in lisp.h.

5284 (DATA_SEG_BITS): Use it.
5285 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
5286 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
5287 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
5288 not be usable in #if. This simplifies things.
5290 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
5292 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
5294 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

5297 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
5298 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
5299 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
5300 Adjust to changes in lisp.h and emacs.c, by using
5301 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
5302 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
5303 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
5304 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
5305 instead of gdb_valbits.
5306 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
5307 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
5308 instead of gdb_array_mark_flag.
5309 (xboolvector): Get size from $->size, not $->header.size.
5310 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
5311 (xreload, hook-run, hookpost-run): Remove.
5312 * emacs.c: Include <verify.h>.
5313 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
5314 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
5316 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
5317 (gdb_USE_LSB_TAG): New enum constants.
5318 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
5319 Also define these as enum constants, so they're visible to GDB.
5320 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
5321 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
5322 as constants, so they're visible to GDB.
5323 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
5324 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
5325 Now enum constants, not macros, so they're visible to GDB.
5326 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
5327 more convenient now. All uses changed.
5328 (VALMASK) [USE_LSB_TAG]: Also define in this case.
5329 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
5331 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>
5333 Explicitly free restriction data that are not needed anymore.
5334 * editfns.c (save_restriction_restore): Free restriction data.
5336 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
5338 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
5339 add argument, tune behavior, and adjust all callers.
5341 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
5343 Use typedef for EMACS_INT, EMACS_UINT.
5344 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
5345 than macros. This simplifies debugging in the usual case, since
5346 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
5347 and it allows expressions involving EMACS_INT casts.
5348 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
5350 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>
5352 * nsterm.m (ns_read_socket): Return early if there is a modal
5355 2012-07-25 Martin Rudalics <rudalics@gmx.at>

5358 that FOCUS-FRAME can be omitted.
5360 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
5362 Adjust buffer text indirection counters at the end of Fkill_buffer.
5363 * buffer.c (Fkill_buffer): Adjust indirection counters when the
5364 buffer is definitely dead. This should really fix an issue reported
5365 by Christoph Scholtes again. (Bug#12007).
5366 (init_buffer_once): Initialize indirection counters of
5367 buffer_defaults and buffer_local_symbols (for sanity and safety).
5369 2012-07-24 Eli Zaretskii <eliz@gnu.org>
5371 * xdisp.c (init_iterator): Don't compute dimensions of truncation
5372 and continuation glyphs on tooltip frames, leave them at zero.
5373 Avoids continued lines in tooltips. (Bug#11832)
5375 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
5377 Simplify copy_overlay.
5378 * buffer.c (copy_overlay): Simplify. Use build_marker.

5384 or invalid. (Bug#12025)
5386 * window.c (decode_any_window): Disable CHECK_LIVE_FRAME test, as
5387 it signals an error when a tooltip frame is being created.
5389 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
5391 Cleanup miscellaneous objects allocation and initialization.
5392 * alloc.c (allocate_misc): Change to static. Add argument to
5393 specify the subtype. Adjust comment and users.
5394 (build_overlay): New function.
5395 * buffer.c (copy_overlays, Fmake_overlay): Use it.
5396 * lisp.h (struct Lisp_Overlay): Remove obsolete comment.
5397 (allocate_misc): Remove prototype.
5398 (build_overlay): Add prototype.
5400 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
5402 Swap buffer text indirection counters in Fbuffer_swap_text.
5403 * buffer.c (Fbuffer_swap_text): Swap indirections too.
5404 This avoids crash reported by Christoph Scholtes at
5405 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
5407 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
5409 * nsmenu.m (Popdown_data): New struct.

6168 The functional style also makes code easier to read and maintain.
6169 * systime.h: Include <sys/time.h> on all hosts, not just if
6170 WINDOWSNT, since 'struct timeval' is needed in general.

6210 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
6211 Prefer snprintf to strncpy.
6212 * nsterm.m (ns_term_init):
6213 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
6214 * nsterm.m (ns_term_init):
6215 Avoid the need for strncpy, by using build_string or
6216 make_unibyte_string directly. Use dtoastr, not snprintf.
6217 * process.c (Fmake_network_process): Diagnose service names that
6218 are too long, rather than silently truncating them or creating
6219 non-null-terminated names.
6220 (Fnetwork_interface_info): Likewise, for interface names.

6236 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
6237 where argument type is known to be a Lisp_Cons.

6292 O_RDONLY already includes it).
6294 Stop ns builds setting the EMACSLOADPATH environment variable.
6295 * nsterm.m (ns_load_path): Rename from ns_init_paths.
6296 Now it does not set EMACSLOADPATH, just returns the load-path string.
6297 * nsterm.h: Update accordingly.
6298 * lread.c [HAVE_NS]: Include nsterm.h.
6299 (init_lread) [HAVE_NS]: Use ns_load_path.

6309 (ns_init_paths): Do not set EMACSPATH.
6310 * nsterm.h (ns_exec_path): Add it.
6311 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
6314 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
6316 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
6318 * process.c (wait_reading_process_output): 'waitchannels' was unset
6319 when read_kbd || !NILP (wait_for_cell); fix this.
6321 Add GCC-style 'const' attribute to functions that can use it.
6322 * character.h (char_resolve_modifier_mask):
6323 * keyboard.h (make_ctrl_char):
6324 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
6325 (init_character_once, next_almost_prime, init_fns, init_image)
6326 (flush_pending_output, init_sound):

6333 Add decls with ATTRIBUTE_CONST.
6335 Minor improvements to make_formatted_string.
6336 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
6337 where int is good enough, as vsprintf returns an int.
6338 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
6340 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
6342 Use make_formatted_string to avoid double length calculation.
6343 * lisp.h (make_formatted_string): New prototype.
6344 * alloc.c (make_formatted_string): New function.
6345 * buffer.c (Fgenerate_new_buffer_name): Use it.

6348 * filelock.c (get_boot_time): Likewise.
6349 * frame.c (make_terminal_frame, set_term_frame_name)
6350 (x_report_frame_params): Likewise.

6363 * nsterm.h (ns_etc_directory): Add it.
6364 * callproc.c [HAVE_NS]: Include nsterm.h.
6365 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
6367 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
6369 Move marker debugging code under MARKER_DEBUG.
6370 * marker.c (MARKER_DEBUG): Move marker debugging code under
6371 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
6372 for bootstrap with --enable-checking (~3x slowdown reported
6373 by Juanma Barranquero <lekktu@gmail.com>).
6374 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
6376 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
6378 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
6379 See <http://bugs.gnu.org/11825#29>.
6381 2012-07-08 Eli Zaretskii <eliz@gnu.org>
6383 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
6384 has no font, use the frame's font. (Bug#11813)
6385 (display_line): Add commentary about displaying truncation glyphs
6387 (produce_special_glyphs): Move here from term.c.
6389 * term.c (produce_special_glyphs): Move to xdisp.c.
6391 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
6394 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
6396 * xdisp.c (display_line): Avoid warning about implicit declaration
6399 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
6401 * lisp.h: Remove empty conditional.
6403 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
6405 * lread.c (load_path_check): Now static.
6407 Fix some minor --with-ns problems found by static checking.
6408 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
6409 (x_set_font) [!HAVE_X_WINDOWS]:
6410 * image.c (xpm_load_image) [HAVE_NS]:
6411 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
6412 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
6413 Remove unused local.
6414 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
6415 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
6416 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
6417 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
6418 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
6419 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
6420 Fix pointer signedness problem.
6421 * xfaces.c (FRAME_X_FONT_TABLE):
6422 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
6424 2012-07-07 Glenn Morris <rgm@gnu.org>
6426 * lread.c (load_path_check): New function, split from init_lread.
6427 (init_lread): Reorganize. Motivation:
6428 If EMACSLOADPATH is set, check/warn about that rather than the
6429 defaults, which we are not going to use. Hence we can remove
6430 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
6431 Don't warn if site-lisp directories are missing.
6432 If not installed, start from a blank load-path, since
6433 PATH_LOADSEARCH refers to the eventual installation directories.
6435 2012-07-07 Eli Zaretskii <eliz@gnu.org>
6437 Support truncation and continuation glyphs on GUI frames, when
6438 fringes are disabled. (Bug#11832)
6439 * xdisp.c (init_iterator): Get dimensions of truncation and
6440 continuation glyphs even if on GUI frames.
6441 Adjust it->last_visible_x on GUI frames when the left or right fringes,
6442 or both, are absent.
6443 (start_display, move_it_in_display_line_to): Handle the case of a
6444 GUI frame without a fringe to display continuation or truncation
6446 (insert_left_trunc_glyphs): Support GUI frames: make sure
6447 truncation glyphs overwrite enough glyphs from the current line to
6448 have sufficient space in pixels.
6449 (display_line): Support truncation and continuation glyphs on GUI
6450 frames. If some spare pixels are left on the line after inserting
6451 the truncation glyphs, fill that space with a stretch glyph of a
6452 suitably computed width.
6454 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
6455 produce_glyphs, to support GUI sessions.
6457 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
6459 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
6461 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
6463 Do not require float-time's arg to fit in time_t (Bug#11825).
6464 This works better on hosts where time_t is unsigned, and where
6465 float-time is applied to the (negative) difference between two times.
6466 * editfns.c (decode_time_components): Last arg is now double *,
6467 not int *, and means to store all the result as a double, without
6468 worrying about whether the seconds part fits in time_t.
6469 All callers changed.
6470 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
6471 All callers changed.
6472 (Ffloat_time): Do not fail merely because the specified time falls
6473 outside of time_t range.
6475 2012-07-07 Glenn Morris <rgm@gnu.org>
6477 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

6484 Update dependencies.
6486 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
6488 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>

6492 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
6493 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
6494 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
6495 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
6497 * xfont.c (compare_font_names): Redo to omit the need for casts.
6499 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
6501 * xfns.c (Fx_change_window_property): Doc fix.
6502 * w32fns.c (Fx_change_window_property): Doc fix.
6504 * w32fns.c (Fx_window_property): Accept the same arguments as the
6505 X Windows version. Doc fix.
6506 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
6508 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
6509 Eli Zaretskii <eliz@gnu.org>
6511 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
6512 Windows-specific code from nt/config.nt moved here.
6513 Obsolete settings removed.
6515 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
6517 * process.c: Avoid unnecessary calls to gettime.
6518 (wait_reading_process_output): Don't get the time of day
6519 when gobbling data immediately and not waiting, as there's no need
6520 for it in that case. This removes a FIXME.
6522 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
6524 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
6525 is defined (Bug#11768).
6527 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6529 Fix marker debugging code.
6530 * marker.c (byte_char_debug_check): Do not perform the check
6531 if buffer is not multibyte.
6532 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
6533 Call byte_char_debug_check with correct arguments.
6535 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6537 Compile marker debugging code only if ENABLE_CHECKING is defined.
6538 * marker.c (byte_char_debug_check, count_markers):
6539 Use only if ENABLE_CHECKING is defined.
6540 (byte_debug_flag): Remove.
6541 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
6542 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
6544 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6546 Avoid code repetition in marker-related functions.
6547 * marker.c (attach_marker): New function.
6548 (Fset_marker, set_marker_restricted, set_marker_both)
6549 (set_marker_restricted_both): Use it.
6550 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
6551 Consistently rename charno to charpos.
6552 (marker_position): Add eassert.
6553 (marker_byte_position): Convert to eassert.

6569 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
6570 (save_restriction_save): Use build_marker.
6571 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
6572 * window.c (save_window_save): Likewise.
6574 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6576 Do not use Fdelete_overlay in delete_all_overlays
6577 to avoid redundant calls to unchain_overlay.
6578 * buffer.c (drop_overlay): New function.
6579 (delete_all_overlays, Fdelete_overlay): Use it.
6580 * minibuf.c (get_minibuffer): Fix comment.
6582 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
6584 Port to OpenBSD 5.1 amd64.
6585 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
6586 This is needed for OpenBSD, and should be harmless on all BSD systems.
6587 Also, include <sys/sysctl.h>, as it should be available on all
6588 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
6589 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
6590 use p_pid member, not kp_proc.pid.
6592 2012-07-06 Glenn Morris <rgm@gnu.org>
6594 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
6596 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
6598 More xmalloc and related cleanup.
6599 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
6600 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:

6606 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
6607 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
6609 Omit needless casts involving void * pointers and allocation.
6610 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
6611 as the former is more robust if P's type is changed.
6612 Prefer xzalloc to xmalloc + memset 0.
6613 Simplify malloc-or-realloc to realloc.
6614 Don't worry about xmalloc returning a null pointer.
6615 Prefer xstrdup to xmalloc + strcpy.
6616 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
6618 * keyboard.c (apply_modifiers_uncached): Prefer local array to
6619 alloca of a constant.
6621 2012-07-05 Eli Zaretskii <eliz@gnu.org>
6623 * xdisp.c (display_line): Fix horizontal pixel coordinates when
6624 hscroll is larger than the line width. Fixes long and futile
6625 looping inside extend_face_to_end_of_line (on a TTY) producing
6626 glyphs that are not needed and thrown away.
6628 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
6630 * marker.c (set_marker_restricted_both): Simplify by using

6646 (update_theme_scrollbar_width, xg_create_scroll_bar):
6647 Use gtk_scrollbar_new (Bug#11768).

6650 (xg_tool_item_stale_p): Call is_box_type.
6651 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
6652 with default display (Bug#11768).

6656 * xdisp.c (window_hscroll_limited): New function.
6657 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
6658 coordinates when window's hscroll is set to insanely large
6661 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
6663 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

6730 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
6731 This should be fixed in a better way; see Eli Zaretskii in
6732 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
6733 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
6735 * fileio.c (time_error_value): Rename from special_mtime.
6736 The old name's problems were noted by Eli Zaretskii in
6737 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
6739 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
6740 This variable's comment says Emacs needs at least one GDB-visible
6741 symbol of type enum pvec_type, to work around GDB problems.
6742 The symbol's value doesn't matter.
6744 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
6745 that causes compilation to fail on pre-C99 compilers.
6747 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
6749 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

6771 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
6772 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
6773 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
6774 (sweep_vectors): Use it. Use local var `total_bytes' instead of
6775 abusing vector->header.next.nbytes.
6776 (live_vector_p): Use PVEC_TYPE.
6777 (mark_object): Adapt code to extract pvectype. Use switch.
6779 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
6781 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
6782 Tighten new eassert a bit.
6784 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
6786 Fix compilation with --enable-gcc-warnings and -O1
6788 * doprnt.c (doprnt): Change type of tem to int, initialize
6789 to avoid compiler warning. Add eassert.
6790 * search.c (simple_search): Initialize match_byte to avoid
6791 compiler warning. Add eassert.
6793 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
6795 Avoid weird behavior with large horizontal scrolls.
6796 Without this change, for example, large hscroll values would
6797 mess up Emacs's display on Fedora 15 x86, presumably due to
6798 overflows in int calculations in the display code.
6799 Also, if buffers had long lines, Emacs would freeze.
6800 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
6801 (set_window_hscroll): New function, containing the old guts of
6802 Fset_window_hscroll. Return the clipped value.
6803 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
6804 This avoids the need to check against PTRDIFF_MAX.
6806 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
6808 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
6810 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
6812 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
6814 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
6815 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
6816 since GCC 4.4.6 issues a bogus warning for them.
6818 Fix bugs in file timestamp newness comparisons.
6819 * fileio.c (Ffile_newer_than_file_p):
6820 * lread.c (Fload): Use full timestamp resolution of files,
6821 not just the 1-second resolution, so that files that are only
6822 slightly newer still count as newer.
6823 * fileio.c (Ffile_newer_than_file_p): Don't assume file
6824 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
6826 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
6828 * fileio.c: Improve handling of file time marker. (Bug#11852)
6829 (special_mtime): New function.
6830 (Finsert_file_contents, Fverify_visited_file_modtime):
6831 Use it to set special mtime values consistently.
6833 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
6835 * fileio.c (Finsert_file_contents): Properly handle st_mtime
6836 marker for non-existing file. (Bug#11852)
6838 2012-07-03 Glenn Morris <rgm@gnu.org>
6840 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
6841 and did not make it into globals.h).
6843 2012-07-03 Tom Tromey <tromey@redhat.com>
6845 * window.c (Fset_window_margins, Fset_window_fringes)
6846 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
6847 * textprop.c (Fprevious_property_change): No longer static.
6848 * syntax.c (Fsyntax_table_p): No longer static.
6849 * process.c (Fget_process, Fprocess_datagram_address): No longer

6859 * doc.c (Fdocumentation_property, Fsnarf_documentation):
6861 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): No longer
6863 * dired.c (Ffile_attributes): No longer static.
6864 * composite.c (Fcomposition_get_gstring): No longer static.
6865 * callproc.c (Fgetenv_internal): No longer static.
6867 * ccl.h: Remove EXFUNs.
6868 * buffer.h: Remove EXFUNs.
6869 * dispextern.h: Remove EXFUNs.
6870 * intervals.h: Remove EXFUNs.
6871 * fontset.h: Remove EXFUN.
6872 * font.h: Remove EXFUNs.
6873 * dosfns.c (system_process_attributes): Remove EXFUN.
6874 * keymap.h: Remove EXFUNs.
6875 * lisp.h: Remove EXFUNs.
6876 * w32term.h: Remove EXFUNs.
6877 * window.h: Remove EXFUNs.
6878 * xsettings.h: Remove EXFUN.
6879 * xterm.h: Remove EXFUN.
6881 2012-07-03 Glenn Morris <rgm@gnu.org>
6883 * lisp.h (Frandom): Make it visible to C.
6884 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
6885 buffer for invisible buffers. (Bug#1229)
6887 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
6889 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
6890 values which aren't power of 2.
6891 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
6892 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
6895 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
6897 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
6899 * alloc.c (mark_object): Revert part of last patch to use `switch'.
6901 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
6903 * alloc.c (allocate_vector_block): Remove redundant
6904 calls to mallopt if DOUG_LEA_MALLOC is defined.
6905 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
6906 avoid calls to mallopt if zero_vector is returned.
6908 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
6910 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
6911 is enabled, avoid dereferencing NULL current_sblock if
6914 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
6916 Cleanup basic buffer management.
6917 * buffer.h (struct buffer): Change layout to use generic vector
6918 marking code. Fix some comments. Change type of 'clip_changed'
6919 to bitfield. Remove unused #ifndef old.
6920 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
6921 (GET_OVERLAYS_AT): Fix indentation.
6922 (for_each_per_buffer_object_at): New macro.
6923 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
6924 (Fbuffer_local_variables): Use it.
6925 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
6926 * alloc.c (allocate_buffer): Adjust to match new layout of
6927 struct buffer. Fix comment.
6928 (mark_overlay): New function.
6929 (mark_buffer): Use it. Use mark_vectorlike to mark normal
6930 Lisp area of struct buffer.
6931 (mark_object): Use it. Adjust marking of misc objects
6932 and related comments.
6934 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
6936 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
6937 wrapper that is not needed because the wrapped code is a no-op (zero
6938 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
6939 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
6941 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
6943 * alloc.c (mark_buffer): Simplify. Remove prototype.
6944 (mark_object): Add comment. Reorganize marking of vector-like
6945 objects. Use CHECK_LIVE for all vector-like objects except buffers
6946 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
6947 Avoid redundant calls to mark_vectorlike for bool vectors.
6949 2012-06-30 Glenn Morris <rgm@gnu.org>
6951 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
6953 * epaths.in (PATH_SITELOADSEARCH): New.
6954 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
6955 This is rather than relying on --enable-locallisppath elements
6956 having "site-lisp" in their names. (Bug#10208#25, 11658)
6958 2012-06-30 Eli Zaretskii <eliz@gnu.org>
6960 * w32proc.c (sys_select): Accept and ignore one more argument.
6962 * w32.c (emacs_gnutls_pull): Call select with one more argument.
6964 * sysselect.h [DOS_NT]: Don't include sys/select.h.
6965 (pselect) [!MS_DOS]: Redirect to sys_select.
6967 * sysdep.c: Don't include dos.h and dosfns.h.
6969 * process.c (sys_select):
6970 * msdos.c (sys_select): Accept one more argument and ignore it.
6972 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
6973 adapt data types and code to that.
6976 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
6977 which clashes with the gnulib function of the same name.
6979 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
6981 * font.c (font_style_to_value, font_style_symbolic)
6982 (font_prop_validate_style): Add type checks for values in
6985 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
6987 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
6990 2012-06-29 Eli Zaretskii <eliz@gnu.org>
6992 * xdisp.c (try_window_id): Undo last change.
6994 * w32.c (getwd): Adjust commentary about startup_dir.
6995 (init_environment): Always call sys_access, even in non-MSVC
6996 builds. Don't chdir to the directory of the Emacs executable.
6997 This undoes code from 1997 which was justified by the need to
6998 "avoid conflicts when removing and renaming directories". But its
6999 downside was that every relative file name was being interpreted
7000 relative to the directory of the Emacs executable, which can never
7001 be TRT. In particular, it broke sys_access when called with
7002 relative file names.
7003 (sys_access): Map GetLastError to errno.
7005 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
7007 * window.h (struct window): Change type of 'fringes_outside_margins'

7011 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
7014 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
7016 * gnutls.c (emacs_gnutls_handshake):
7017 Add QUIT to make the loop interruptible.
7019 2012-06-29 Glenn Morris <rgm@gnu.org>
7021 * charset.c (init_charset): Make lack of etc/charsets fatal.
7023 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
7025 * editfns.c (region_limit): Fix type mismatch.
7027 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
7029 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
7030 undefined. Convert from xassert to eassert.
7031 * nsmenu.m: Convert from xassert to eassert.
7032 * nsterm.m: Likewise.
7034 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
7036 * editfns.c (region_limit): Clip to narrowing (bug#11770).
7038 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
7040 Avoid integer overflow on scroll-left and scroll-right.
7041 * window.c (HSCROLL_MAX): New macro.
7042 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
7043 overflow when requested scroll falls outside ptrdiff_t range.
7045 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
7047 * window.h (struct window): Change type of 'hscroll',
7048 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
7049 'last_modified' and 'last_overlay_modified' to EMACS_INT.
7050 Adjust users accordingly.
7051 * xdisp.c (try_cursor_movement): Replace type check with eassert.
7052 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
7053 from EMACS_INT to ptrdiff_t.
7054 (make_window): Omit redundant initialization.
7056 2012-06-28 Juanma Barranquero <lekktu@gmail.com>

7060 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
7062 * window.h (struct window): Change type of 'use_time' and
7063 'sequence_number' from Lisp_Object to int.

7073 Fix GLYPH_DEBUG usage assuming that it may be undefined,
7074 adjust comments accordingly.

7123 * alloc.c (allocate_string_data): Remove dead code.
7124 * xsettings.c (XSETTINGS_FONT_NAME): Move under HAVE_XFT to
7125 avoid GCC warning about unused macro.
7127 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
7129 * alloc.c (allocate_string): Omit intervals initialization.
7130 * alloc.c (make_uninit_multibyte_string): Initialize intervals
7131 as in make_pure_string and make_pure_c_string.
7133 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
7135 * alloc.c (allocate_string): Fix last change.
7137 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>

7175 * frame.c (make_frame): Omit redundant initialization.

7187 * alloc.c: Remove build_string.
7188 * lisp.h: Define build_string as static inline. This provides
7189 a better opportunity to optimize away calls to strlen when the
7190 function is called with compile-time constant argument.
7191 * image.c (imagemagick_error): Convert to build_string.
7192 * w32proc.c (sys_spawnve): Likewise.
7193 * xterm.c (x_term_init): Likewise.
7195 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
7197 Use sprintf return value instead of invoking strlen on result.
7198 In the old days this wasn't portable, since some sprintf
7199 implementations returned char *. But they died out years ago and
7200 Emacs already assumes sprintf returns int.
7201 Similarly for float_to_string.
7202 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
7203 * ccl.c (ccl_driver):
7204 * character.c (string_escape_byte8):

7207 * print.c (print_object):
7208 * xdisp.c (message_dolog):
7209 * xfns.c (syms_of_xfns):
7210 Use sprintf or float_to_string result to avoid need to call strlen.
7211 * data.c (Fnumber_to_string):
7212 Use make_unibyte_string, since the string must be ASCII.
7213 * lisp.h, print.c (float_to_string): Now returns int length.
7214 * term.c (produce_glyphless_glyph):
7215 Use sprintf result rather than recomputing it.
7217 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
7218 * Makefile.in (ALL_CFLAGS):
7219 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

7225 strcasecmp if available.

7241 2012-06-25 Paul Eggert <eggert@cs.ucla.edu>
7243 * gtkutil.c (get_utf8_string): Remove redundant assignment.
7244 sprintf already null-terminates its output.
7246 * xfns.c (x_window): Remove redundant cast.
7248 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
7250 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
7251 `const char *' to `char *' to avoid compiler warning.
7253 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
7255 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
7256 instead of truncating it to 63 (admittedly a generous limit).
7258 * process.c: Fix spelling and caps in comments.
7260 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
7262 * emacs.c (setpgrp): Remove definition, unused.

7272 (SYSTIME_H): Add nt/inc/sys/time.h.
7274 * systime.h [WINDOWSNT]: Include sys/time.h.

7386 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
7388 Support higher-resolution time stamps (Bug#9000).
7389 The time stamps are only nanosecond-resolution at the C level,
7390 since that's the best that any real-world system supports now.
7391 But they are picosecond-resolution at the Lisp level, as that's
7392 easy, and leaves room for future OS improvements.
7394 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
7397 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
7398 Don't get current time unless it's needed.
7400 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
7401 now provides it if it's absent.
7402 (start_atimer): Port to higher-res time stamps.
7403 Check for time stamp overflow. Don't get current time more
7404 often than is needed.
7406 * buffer.h (struct buffer): Buffer modtime now has high resolution.
7407 Include systime.h, not time.h.
7408 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
7410 * dired.c: Include stat-time.h.
7411 (Ffile-attributes): File times now have higher resolution.

7414 (struct image): Timestamp now has higher resolution.
7416 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
7417 has at least microseconds now. All uses removed.
7418 (update_frame, update_single_window, update_window, update_frame_1)
7419 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
7420 (duration_to_sec_usec): Remove; no longer needed.
7422 * editfns.c (time_overflow): Now extern.

7428 (decode_time_components, lisp_seconds_argument): New functions.
7429 (make_time): Now static.
7430 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
7431 Report an error if the time is invalid, rather than having the caller
7434 * fileio.c: Include <stat-time.h>
7435 (Fcopy_file): Copy higher-resolution time stamps.
7436 Prefer to set the time stamp via a file descriptor if that works.

7438 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
7439 (Fvisited_file_modtime, Fset_visited_file_modtime):
7440 Support higher-resolution time stamps.
7442 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
7444 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
7446 * image.c (prepare_image_for_display, clear_image_cache)
7447 (lookup_image): Port to higer-resolution time stamps.
7449 * keyboard.c (start_polling, bind_polling_period):
7450 Check for time stamp overflow.
7451 (read_char, kbd_buffer_get_event, timer_start_idle)
7452 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
7453 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
7454 Port to higher-resolution time stamps. Do not assume time_t is signed.
7455 (decode_timer): New function. Timers are now vectors of length 9,
7456 not 8, to accommodate the picosecond component.
7457 (timer_check_2): Use it.
7459 * nsterm.m (select_timeout, timeval_subtract): Remove.
7460 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
7461 as they're a bit more accurate and handle overflow better.
7462 (ns_select): Change prototype to be compatible with pselect.
7463 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
7464 * nsterm.h (ns_select): Adjust prototype.
7466 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
7467 us-resolution time stamps.
7468 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
7470 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
7472 * lisp.h (time_overflow): New decl.
7473 (wait_reading_process_output): First arg is now intmax_t, not int,
7474 to accommodate larger waits.
7476 * process.h (struct Lisp_Process.read_output_delay):
7477 Now counts nanoseconds, not microseconds.
7478 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
7480 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
7481 (wait_reading_process_output):
7482 Port to ns-resolution time stamps.
7483 (Faccept_process_output, wait_reading_process_output):
7484 Check for time stamp overflow. Do not assume time_t is signed.
7485 (select_wrapper): Remove; we now use pselect.
7486 (Fprocess_attributes): Now generates ns-resolution time stamps.
7488 * sysdep.c: Include utimens.h. Don't include utime.h
7489 or worry about struct utimbuf; gnulib does that for us now.
7490 (gettimeofday): Remove; gnulib provides a substitute.
7491 (make_timeval): New function.
7492 (set_file_times): Now sets ns-resolution time stamps.
7493 New arg FD; all uses changed.
7494 (time_from_jiffies, ltime_from_jiffies, get_up_time)
7495 (system_process_attributes):
7496 Now returns ns-resolution time stamp. All uses changed.
7497 Check for time stamp overflow.
7499 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
7500 provides a substitute now.
7502 * systime.h: Include timespec.h rather than sys/time.h and time.h,
7503 since it guarantees struct timespec.
7504 (EMACS_TIME): Now struct timespec, so that we can support
7505 ns-resolution time stamps.
7506 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
7507 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
7508 (EMACS_USECS): Remove.
7509 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
7510 so multiply the arg by 1000 before storing it.
7511 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
7513 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
7514 Port to ns-resolution time stamps.
7515 (EMACS_TIME_NEG_P): Remove; replaced by....
7516 (EMACS_TIME_SIGN): New macro.
7517 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
7518 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
7519 (set_file_times, make_time, lisp_time_argument): Adjust signature.
7520 (make_timeval, make_lisp_time, decode_time_components): New decls.
7521 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
7522 that it mishandled time_t overflow. You can't compare by subtracting!
7523 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
7524 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
7526 * term.c: Include <sys/time.h>.
7527 (timeval_to_Time): New function, for proper overflow wraparound.

7532 (Fprimitive_undo): Use them when restoring time stamps.
7534 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
7535 (w32_get_internal_run_time):
7536 Port to higher-resolution Emacs time stamps.
7537 (ltime): Now accepts single 64-bit integer, as that's more convenient
7540 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
7542 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
7543 for compatibility with pselect. Support ns-resolution time stamps.
7545 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
7547 * xselect.c (wait_for_property_change, x_get_foreign_selection):
7548 Check for time stamp overflow, and support ns-resolution time stamps.
7550 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
7551 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
7552 (timeval_subtract): Remove; no longer needed.
7553 (XTflash, XTring_bell, x_wait_for_event):
7554 Port to ns-resolution time stamps. Don't assume time_t is signed.
7556 2012-06-22 Chong Yidong <cyd@gnu.org>

7560 2012-06-22 Eli Zaretskii <eliz@gnu.org>
7562 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
7563 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
7564 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
7565 staticidx goes up to 1597 out of 1600 = 0x640.)
7567 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
7569 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
7570 Otherwise, the umask might be mistakenly 0 while handling input signals.

7581 access to `contents' member of Lisp_Vector objects with AREF and ASET
7584 2012-06-19 Chong Yidong <cyd@gnu.org>
7586 * frame.c (delete_frame): When selecting a frame on a different

7591 (unwind_format_mode_line): Restore them.
7592 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
7594 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
7595 since tty frames can be explicitly named.
7596 (prepare_menu_bars): Likewise.
7598 * term.c (Ftty_top_frame): New function.
7600 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

7603 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
7604 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
7605 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
7606 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
7607 (METER_1, METER_2): Simplify.
7609 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>

7613 2012-06-18 Martin Rudalics <rudalics@gmx.at>
7615 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
7616 gets killed during executing of this function (Bug#11665).
7617 Try to always return Qt when the buffer has been actually killed.
7618 (Vkill_buffer_query_functions): In doc-string say that functions
7619 run by this hook should not change the current buffer.
7621 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
7623 Fix recently-introduced process.c problems found by static checking.

7641 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
7643 * lisp.h (eassert): Assume C89 or later.
7644 This removes the need for CHECK.
7645 (CHECK): Remove. Its comments about always evaluating its
7646 argument were confusing, as 'eassert' typically does not evaluate
7649 * coding.c (produce_chars): Use ptrdiff_t, not int.
7651 * xterm.c (x_draw_underwave): Check for integer overflow.
7652 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

7836 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
7837 code works fine either way, and efficiency is not a concern here,
7838 as the union type is for debugging, not for production.
7839 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
7840 Use an inline function on all platforms when using the union type,
7841 since this is simpler and 'static inline' can be used portably
7843 (LISP_INITIALLY_ZERO): New macro.
7844 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
7845 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.

7927 * xdisp.c (vmessage): Treat frame message as multibyte.
7928 Without this change, (let ((§ 1)) (make-variable-buffer-local '§))

7948 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
7950 2012-06-08 Eli Zaretskii <eliz@gnu.org>
7952 * alloc.c (allocate_vectorlike): Fix last change.

7983 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
7985 * doprnt.c (doprnt): Truncate multibyte char correctly.
7986 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
7987 would mishandle a string argument "Xc" if X was a multibyte
7988 character of length 2: it would truncate after X's first byte
7989 rather than including all of X.
7991 2012-06-06 Chong Yidong <cyd@gnu.org>
7993 * buffer.c (word_wrap): Doc fix.

8042 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
8043 Convert pctcpu and pctmem to Lisp float properly.
8044 Let the compiler fold better, as 100.0/0x8000 is exact.
8046 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
8048 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
8051 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
8053 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
8055 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>

8063 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
8064 fields from Lisp_Object to bitfield. Adjust users accordingly.

8072 and 'double' in a couple of places.
8074 2012-05-31 Eli Zaretskii <eliz@gnu.org>
8076 * xdisp.c (handle_stop): Detect whether we have overlay strings
8077 loaded by testing it->current.overlay_string_index to be
8078 non-negative, instead of checking whether n_overlay_strings is
8079 positive. (Bug#11587)
8081 2012-05-31 Chong Yidong <cyd@gnu.org>
8083 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

8089 * search.c (search_buffer): Remove calls to
8090 r_alloc_inhibit_buffer_relocation, as it is now called by
8091 maybe_unify_char, which was the cause of relocation of buffer text
8094 2012-05-31 Eli Zaretskii <eliz@gnu.org>
8096 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
8097 for the duration of call to load_charset, to avoid problems with
8098 callers of maybe_unify_char that access buffer text through C
8101 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
8102 decrement the inhibition flag, instead of just setting or
8105 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
8107 Remove obsolete '#define static' cruft.
8108 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
8109 This #undef was "temporary" in 2000; it is no longer needed
8110 now that '#define static' has gone away.
8111 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
8112 (gray_bitmap_bits): Remove; no longer needed.
8113 All uses replaced with definiens.

8157 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
8158 Bug#9642, but explicitly check that the buffer the overlay would
8159 be moved to is live and rearrange lines to make sure that errors
8160 will not put the overlay in an inconsistent state.
8161 (Fdelete_overlay): Cosmetics.
8163 2012-05-28 Eli Zaretskii <eliz@gnu.org>
8165 * w32term.c (my_bring_window_to_top): New function.

8204 before checking whether it's out of range. Put the check inside
8206 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.

8220 they are now on lisp.h.
8222 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
8224 * search.c (search_buffer): Use it to inhibit relocation of buffer
8225 text while re_search_2 is doing its job, because re_search_2 is
8226 passed C pointers to buffer text. (Bug#11519)
8228 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
8231 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
8232 state after an additional call to move_it_in_display_line_to, keep
8233 the values of it->max_ascent and it->max_descent found for the
8235 (pos_visible_p): Revert the comparison against bottom_y to what it
8236 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.

8241 Fix coding-related core dumps with gcc -ftrapv.
8242 The code was computing A - B, where A and B are pointers, and B is
8243 random garbage. This can lead to core dumps on platforms that
8244 have special pointer registers, and it also leads to core dumps on
8245 x86-64 when compiled with gcc -ftrapv. The fix is to compute
8246 A - B only when B is initialized properly.
8247 * coding.c (coding_set_source, coding_set_destination): Return void.
8248 (coding_change_source, coding_change_destinations): New functions,
8249 with the old behaviors of coding_set_source and coding_set_destination.

8267 * w32inevt.c: Include termchar.h and window.h.
8268 (do_mouse_event): Support mouse-autoselect-window. When the mouse
8269 moves, call note_mouse_highlight. If help_echo changed, call
8270 gen_help_event to produce help-echo message in the echo area.
8271 Call clear_mouse_face if mouse_face_hidden is set in the mouse
8274 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
8276 * lread.c (read1): Simplify slightly to avoid an overflow warning
8277 with GCC 4.7.0 on x86-64.
8279 2012-05-26 Eli Zaretskii <eliz@gnu.org>
8281 * bidi.c (bidi_mirror_char): Revert last change: an int is
8282 definitely wide enough here.
8284 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>

8298 Use int, not EMACS_INT, where int is wide enough.
8299 (inhibit_garbage_collection, Fgarbage_collect):
8300 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

8318 (Foverlay_recenter, last_overlay_modification_hooks_used)
8319 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
8320 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8321 (validate_region): Omit unnecessary test for b <= e,
8322 since that's guaranteed by the previous test.
8323 (adjust_overlays_for_delete): Avoid pos + length overflow.
8324 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
8325 (report_overlay_modification):
8326 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
8327 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):

8329 after the EMACS_INT -> ptrdiff_t change.

8336 not int, to avoid needless 32-bit limit on 64-bit hosts.
8337 (exec_byte_code): Use tighter memory-full test, one that checks
8338 for alloca overflow. Don't compute the address of the object just
8339 before an array, as that's not portable. Use EMACS_INT, not
8340 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
8341 * callint.c (Fcall_interactively):
8342 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

8354 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8355 (casify_object): Avoid integer overflow when overallocating buffer.
8356 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
8357 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
8358 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
8359 * category.h (CATEGORYP): Don't assume arg is nonnegative.
8360 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
8361 integers are now checked earlier. All uses replaced with XINT.
8363 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8364 For CCL_MapSingle, check that content and value are in int range.
8365 (ccl_driver, Fregister_code_conversion_map):
8366 Check that Vcode_version_map_vector is a vector.
8367 (resolve_symbol_ccl_program): Check that vector header is in range.
8368 Always copy the vector, so that we can check its contents reliably
8369 now rather than having to recheck each instruction as it's being
8370 executed. Check that vector words fit in 'int'.
8371 (ccl_get_compiled_code, Fregister_ccl_program)
8372 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
8373 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
8374 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
8375 contents are in range.
8376 (Fccl_execute_on_string): Check that status is in range.
8377 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
8378 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
8379 Accept and return EMACS_INT, not int, because callers can pass values

8386 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8387 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
8388 avoid mishandling large integers.

8399 Don't rely on undefined behavior with signed left shift overflow.
8400 Don't assume unsigned int fits into fixnum, or that fixnum fits
8401 into unsigned int. Don't require max_code to be a valid fixnum;
8402 that's not true for gb10830 4-byte on a 32-bit host. Allow
8403 invalid_code to be a cons, for the same reason. Require code_offset
8404 to be a character. Avoid int overflow if max_char is close
8406 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
8407 this is intended anyway and avoids some undefined behavior.
8408 (load_charset_map): Pass unsigned, not int, as 2nd arg of
8409 INDEX_TO_CODE_POINT, as that's what it expects.
8410 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
8411 * charset.h (DECODE_CHAR): Return int, not unsigned;
8412 this is what was intended anyway, and it avoids undefined behavior.
8413 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
8414 integer-overflow issues.
8415 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
8416 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
8417 where the argument is EMACS_INT, and this behavior is not intended.
8418 * chartab.c (Fmake_char_table, Fset_char_table_range)
8419 (uniprop_get_decoder, uniprop_get_encoder):
8420 Don't assume fixnum fits in int.
8421 * cmds.c (move_point): New function, that does the gist of
8422 Fforward_char and Fbackward_char, but does so while checking
8423 for integer overflow more accurately.
8424 (Fforward_char, Fbackward_char): Use it.
8425 (Fforward_line, Fend_of_line, internal_self_insert)
8426 (internal_self_insert):
8427 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

9129 define them any more.

9137 * s/ms-w32.h (DATA_START):
9138 Move here from removed file m/intel386.h.

9193 2012-05-17 Juri Linkov <juri@jurta.org>

9197 (Fword_search_forward_lax): Move functions to isearch.el
9198 (bug#10145, bug#11381).
9200 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
9202 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).

9208 2012-05-14 Glenn Morris <rgm@gnu.org>
9210 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
9211 Put "libexec" before "bin", for the sake of init_callproc_1.
9213 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
9215 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
9217 * unexaix.c: Port to more-recent AIX compilers.
9218 (report_error, report_error_1, make_hdr, copy_sym)
9219 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
9220 Make arguments const char *, not char *, to avoid violations of C
9221 standard and to fix some AIX warnings reported by Gilles Pion.
9223 2012-05-14 Eli Zaretskii <eliz@gnu.org>
9225 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
9226 already have overlays loaded.
9227 (handle_single_display_spec): Before returning without displaying
9228 fringe bitmap, synchronize the bidi iterator with the main display
9229 iterator, by calling iterate_out_of_display_property.
9230 (iterate_out_of_display_property): Detect buffer iteration by
9231 testing that it->string is a Lisp string.
9232 (get_next_display_element): When the current object is exhausted,
9233 and there's something on it->stack, call set_iterator_to_next to
9234 proceed with what's on the stack, instead of returning zero.
9235 (set_iterator_to_next): If called at the end of a Lisp string,
9236 proceed to consider_string_end without incrementing string
9237 position. Don't increment display vector index past the end of
9238 the display vector. (Bug#11417)
9239 (pos_visible_p): Don't report a position visible when move_it_to
9240 stopped at the last line of window, which happens to be scanned
9241 backwards by the bidi iteration. (Bug#11464)
9243 2012-05-14 Eli Zaretskii <eliz@gnu.org>
9245 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
9246 and right-margin display specs even if the spec is invalid or we
9247 are on a TTY, and thus unable to display on the fringes.
9248 That's because the text with the property will not be displayed anyway,
9249 so we need to signal to the caller that this is a "replacing"
9250 display spec. This fixes display when the spec is invalid or we
9253 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
9255 * unexaix.c (make_hdr): Fix typo in prototype.
9256 This bug broke the build on AIX. Problem reported by Gilles Pion.
9258 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
9260 * keyboard.c (kbd_buffer_get_event): Read special events also in
9261 batch mode. (Bug#11415)
9263 2012-05-12 Glenn Morris <rgm@gnu.org>

9271 2012-05-12 Glenn Morris <rgm@gnu.org>
9273 * Makefile.in (MKDIR_P): New, set by configure.
9274 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
9276 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
9278 Remove unused function hourglass_started.
9279 * dispextern.h (hourglass_started):
9280 * w32fns.c (hourglass_started):
9281 * xdisp.c (hourglass_started): Remove.

9286 Update dependencies.
9288 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
9290 * xgselect.c (xg_select): Put maxfds+1 into a var.
9291 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
9293 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
9295 2012-05-10 Dave Abrahams <dave@boostpro.com>
9297 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
9298 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
9300 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
9302 * dbusbind.c (xd_registered_buses): New internal Lisp object.
9303 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
9304 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
9305 Initialize xd_registered_buses.
9307 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
9309 Untag more efficiently if USE_LSB_TAG.
9310 This is based on a proposal by YAMAMOTO Mitsuharu in
9311 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
9312 For an admittedly artificial (nth 8000 longlist) benchmark on
9313 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
9314 Emacs's overall text size by 1%.
9315 * lisp.h (XUNTAG): New macro.
9316 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
9317 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
9318 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
9319 * eval.c (Fautoload):
9320 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
9321 * frame.h (XFRAME): Use XUNTAG.
9323 Port recent dbusbind.c changes to 32-bit --with-wide-int.
9324 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
9325 Remove unportable assumptions about print widths of types like
9327 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
9328 intptr_t when converting between pointer and integer, to avoid GCC
9329 warnings about wrong width.
9331 2012-05-09 Eli Zaretskii <eliz@gnu.org>
9333 * w32proc.c (new_child): Force Windows to reserve only 64KB of
9334 stack for each reader_thread, instead of defaulting to 8MB
9335 determined by the linker. This avoids failures in creating
9336 subprocesses on Windows 7, see the discussion in this thread:

9341 Fix up display of the *Minibuf-0* buffer in the mini window.
9342 * keyboard.c (read_char): Don't clear the echo area if there's no
9344 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
9345 contents of *Minibuf-0*) if there's no message displayed in its stead.
9347 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
9349 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
9352 2012-05-06 Chong Yidong <cyd@gnu.org>
9354 * lisp.mk (lisp): Update.
9356 2012-05-05 Jim Meyering <meyering@redhat.com>
9358 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
9360 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
9362 * data.c (PUT_ERROR): New macro.
9363 (syms_of_data): Use it. Add new error type `user-error'.
9364 * undo.c (user_error): New function.
9365 (Fprimitive_undo): Use it.
9366 * print.c (print_error_message): Adjust print style for `user-error'.
9367 * keyboard.c (user_error): New function.
9368 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
9370 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
9372 Do not limit current-time-string to years 1000..9999.
9373 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
9374 (Fcurrent_time_string): Support any year that is supported by the
9375 underlying localtime representation. Don't use asctime, as it
9376 has undefined behavior for years outside the range -999..9999.
9378 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
9380 Fix race conditions involving setenv, gmtime, localtime, asctime.
9381 Without this fix, interrupts could mess up code that uses these
9382 nonreentrant functions, since setting TZ invalidates existing
9383 tm_zone or tzname values, and since most of these functions return
9384 pointers to static storage.
9385 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
9386 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
9387 Grow the critical sections to include not just invoking
9388 localtime/gmtime, but also accessing these functions' results
9389 including their tm_zone values if any, and any related TZ setting.
9390 (format_time_string): Last arg is now struct tm *, not struct tm **,
9391 so that the struct tm is saved in the critical section.
9392 All callers changed. Simplify allocation of initial buffer, partly
9393 motivated by the fact that memory allocation needs to be outside
9394 the critical section.
9396 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
9398 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
9399 with RESET_INTERVAL.
9401 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
9402 Remove duplicated buffer name initialization.
9404 2012-05-02 Jim Meyering <jim@meyering.net>
9406 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
9408 * xfns.c (x_window): Use xstrdup (Bug#11375).
9410 2012-05-02 Eli Zaretskii <eliz@gnu.org>
9412 * xdisp.c (pos_visible_p): If already at a newline from the
9413 display string before the 'while' loop, don't walk back the glyphs
9414 from it3.glyph_row. Solves assertion violation when the display
9415 string begins with a newline (egg.el). (Bug#11367)
9417 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
9419 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
9422 2012-05-01 Glenn Morris <rgm@gnu.org>
9424 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
9425 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
9426 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
9427 All were removed before 23.1.
9429 * dispnew.c: Remove HAVE_LIBNCURSES test;
9430 it is always true on relevant platforms.
9432 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
9433 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
9435 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
9437 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
9439 * .gdbinit (xpr): Remove checks for no longer existing misc types.
9440 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
9443 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
9445 Do not avoid creating empty evaporating overlays (Bug#9642).
9446 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
9447 That is, do not delete an evaporating overlay if it becomes
9448 empty after its bounds are adjusted to fit within its buffer.
9449 This fix caused other problems, and I'm reverting it until we get
9450 to the bottom of them.
9452 2012-04-27 Chong Yidong <cyd@gnu.org>
9454 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
9456 2012-04-27 Eli Zaretskii <eliz@gnu.org>
9458 * xdisp.c (pos_visible_p): If the window start position is beyond
9459 ZV, start the display from buffer beginning. Prevents assertion
9460 violation in init_iterator when the minibuffer window is scrolled
9463 * window.c (window_scroll_pixel_based): Likewise.
9465 2012-04-27 Chong Yidong <cyd@gnu.org>
9467 * keymap.c (where_is_internal): Doc fix (Bug#10872).
9469 2012-04-27 Glenn Morris <rgm@gnu.org>
9471 * fileio.c (Fcopy_file, Fset_file_selinux_context):
9472 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
9474 2012-04-27 Eli Zaretskii <eliz@gnu.org>
9476 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
9477 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
9479 2012-04-26 Eli Zaretskii <eliz@gnu.org>
9481 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
9482 display element, check also the underlying string or buffer
9483 character. (Bug#11341)
9485 * w32menu.c: Include w32heap.h.
9486 (add_menu_item): If the call to AppendMenuW (via
9487 unicode_append_menu) fails, disable Unicode menus only if we are
9488 running on Windows 9X/Me.
9490 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
9492 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
9493 (xgetint): Add missing shift for LSB tags.
9495 2012-04-24 Martin Rudalics <rudalics@gmx.at>
9497 * keyboard.c (read_char): Don't wipe echo area for select window
9498 events: These might get delayed via `mouse-autoselect-window'
9501 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
9503 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
9504 manipulation of :loaded-from data.
9506 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
9508 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
9509 now a cons (bug#11311).
9511 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
9513 Do not create empty overlays with the evaporate property (Bug#9642).
9514 * buffer.c (Fmove_overlay): Delete an evaporating overlay
9515 if it becomes empty after its bounds are adjusted to fit within
9516 its buffer. Without this fix, in a nonempty buffer (let ((o
9517 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
9518 yields an empty overlay that has the evaporate property, which is
9519 not supposed to happen.
9521 Fix minor GTK3 problems found by static checking.
9522 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
9523 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
9524 (struct _EmacsFixedClass, emacs_fixed_get_type):

9532 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
9533 (EMACS_FIXED_GET_CLASS): Remove; unused.
9534 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
9536 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
9537 Problem reported by Juanma Barranquero for Windows -Wunused-function.
9539 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
9541 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
9542 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
9543 (__malloc_size_t, __malloc_ptrdiff_t):
9544 Remove. All uses removed, replaced by the definiens if needed,
9545 since we can assume C89 or better now.
9546 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.

9555 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
9556 Define using prototypes, not old style.
9557 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
9558 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
9559 (align): Don't assume that signed integer overflow wraps around.
9560 Omit unused local var.
9561 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)

9738 * lisp.h (r_alloc, r_alloc_free, r_re_alloc, r_alloc_reset_variable)
9739 [REL_ALLOC]: ... to here, to check interface.
9740 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
9741 Remove decls. This fixes an "It stinks!".
9743 * alloc.c (which_symbols): Fix alignment issue / type clash.

9765 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
9766 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
9767 no longer the default.
9768 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
9770 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

9791 * indent.c (Fmove_to_column): Change interactive spec (Bug#739).
9793 2012-04-11 Daniel Colascione <dancol@dancol.org>
9795 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
9796 against is gone. It's better to use vfork now so that when Cygwin
9797 gains a new, working vfork, we use it automatically (bug#10398).
9799 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

9807 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
9809 * alloc.c (lisp_align_malloc): Remove unneeded prototype.
9811 2012-04-10 Jason S. Cornez <jcornez@ravenpack.com> (tiny change)
9813 * keyboard.c: Override inhibit-quit after the third C-g (bug#6585).
9814 (force_quit_count): New var.
9815 (handle_interrupt): Use it.
9817 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
9819 * w32.c (w32_delayed_load): Record the full path of the library
9820 being loaded (bug#10424).
9822 2012-04-09 Glenn Morris <rgm@gnu.org>
9824 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
9825 not just in the obarray, before snarfing them. (Bug#11036)
9827 * Makefile.in ($(leimdir)/leim-list.el):
9828 Pass EMACS rather than BUILT_EMACS.
9830 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
9832 * process.c (make_process):
9833 * process.h: Add integer `gnutls_handshakes_tried' member to
9836 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.
9837 Add convenience `GNUTLS_LOG2i' macro.
9839 * gnutls.c (gnutls_log_function2i): Convenience log function.
9840 (emacs_gnutls_read): Use new log functions,
9841 `gnutls_handshakes_tried' process member, and
9842 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
9843 attempts per process (connection).
9845 2012-04-09 Chong Yidong <cyd@gnu.org>
9847 * eval.c (Fuser_variable_p, user_variable_p_eh)
9848 (lisp_indirect_variable): Functions deleted.
9849 (Fdefvar): Caller changed.
9851 * callint.c (Finteractive, Fcall_interactively):
9852 * minibuf.c (Fread_variable): Callers changed.
9854 2012-04-09 Eli Zaretskii <eliz@gnu.org>
9856 * xdisp.c (set_cursor_from_row): If the display string appears in
9857 the buffer at position that is closer to point than the position
9858 after the display string, display the cursor on the first glyph of
9859 the display string. Fixes cursor display when a 'display' text
9860 property immediately follows invisible text. (Bug#11094)
9862 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
9864 composite.c: use 'double' consistently
9865 * composite.c (get_composition_id): Use 'double' consistently
9866 instead of converting 'float' to 'double' and vice versa; this is
9867 easier to understand and avoids a GCC warning.
9869 2012-04-09 Glenn Morris <rgm@gnu.org>
9871 * Makefile.in: Generate leim-list with bootstrap-emacs, in
9872 preparation for dumping it with emacs. (Bug#4789)
9873 (leimdir): New variable.
9874 ($(leimdir)/leim-list.el): New rule.
9875 (emacs$(EXEEXT)): Depend on leim-list.el.
9877 * buffer.c (Qucs_set_table_for_input): Remove. (Bug#9821)
9878 (Fget_buffer_create): Don't call Qucs_set_table_for_input.
9879 (init_buffer_once, syms_of_buffer): Remove Qucs_set_table_for_input.
9881 2012-04-08 Andreas Schwab <schwab@linux-m68k.org>
9883 * lisp.h (struct Lisp_Symbol): Add explicit padding to ensure
9886 2012-04-07 Juanma Barranquero <lekktu@gmail.com>
9888 * xml.c (init_libxml2_functions) [WINDOWSNT]:
9889 Remove unused local variable.
9891 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
9893 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
9894 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
9895 (mark_memory): Mark Lisp_Objects only if pointers might hide in
9896 objects, as mark_maybe_pointer will catch them otherwise.
9897 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
9898 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
9900 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
9902 Fix typo that broke non-Windows builds.
9903 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.
9905 2012-04-07 Eli Zaretskii <eliz@gnu.org>
9907 Support building on MS-Windows with libxml2.
9909 * makefile.w32-in (OBJ2): Add xml.$(O).
9910 (GLOBAL_SOURCES): Add xml.c.
9911 ($(BLD)/xml.$(O)): New dependency list.
9913 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
9914 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
9915 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
9916 [!WINDOWSNT]: New macros.
9917 (init_libxml2_functions, libxml2_loaded_p): New functions.
9918 (parse_region): Call fn_xmlCheckVersion instead of using the macro
9919 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
9920 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
9921 Calls xmlCleanupParser only if libxml2 was loaded (or statically
9923 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
9924 Call init_libxml2_functions before calling libxml2 functions.
9925 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
9927 * emacs.c: Don't include libxml/parser.h.
9928 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
9929 xmlCleanupParser directly.
9931 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
9933 2012-04-07 Eli Zaretskii <eliz@gnu.org>
9935 * indent.c (Fvertical_motion): If there is a display string at
9936 point, use it.vpos to compute how many lines to backtrack after
9937 move_it_to point. (Bug#11133)
9939 2012-04-06 Eli Zaretskii <eliz@gnu.org>
9941 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
9942 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
9943 about subtle differences between FETCH_CHAR* and STRING_CHAR*
9944 macros related to unification of CJK characters. For the details,
9945 see the discussion following the message here:
9946 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
9948 2012-04-04 Chong Yidong <cyd@gnu.org>
9950 * keyboard.c (Vdelayed_warnings_list): Doc fix.
9952 2012-04-01 Eli Zaretskii <eliz@gnu.org>
9954 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
9955 instead of alloca. (Bug#11138)
9957 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
9959 * w32menu.c (is_simple_dialog): Properly check lisp types.
9962 2012-03-31 Eli Zaretskii <eliz@gnu.org>
9964 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
9965 position we get to after a call to move_it_to fails the
9966 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
9967 only if we wind up in a string from display property. (Bug#11063)
9969 * window.c (Fdelete_other_windows_internal): Invalidate the row
9970 and column information about mouse highlight, so that redisplay
9971 restores it after reallocating the glyph matrices. (Bug#7464)
9973 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
9974 string comes from a `display' text property, use the buffer
9975 position of that property as if we actually saw that position in
9977 (move_it_by_lines): Remove the assertion that
9978 "it->current_x == 0 && it->hpos == 0" which can be legitimately
9979 violated when there's a before-string at the beginning of a line.
9982 2012-03-30 Eli Zaretskii <eliz@gnu.org>
9984 * xdisp.c (append_space_for_newline): If the default face was
9985 remapped, use the remapped face for the appended newline.
9986 (extend_face_to_end_of_line): Use the remapped default face for
9987 extending the face to the end of the line.
9988 (display_line): Call extend_face_to_end_of_line when the default
9989 face was remapped. (Bug#11068)
9991 2012-03-29 Eli Zaretskii <eliz@gnu.org>
9993 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
9995 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
9997 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
9999 2012-03-27 Glenn Morris <rgm@gnu.org>
10001 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
10004 2012-03-26 Kenichi Handa <handa@m17n.org>
10006 * dispextern.h (struct glyph): Fix previous change. Change the
10007 bit length of glyphless.ch to 25 (Bug#11082).
10009 2012-03-26 Chong Yidong <cyd@gnu.org>
10011 * keyboard.c (Vselection_inhibit_update_commands): New variable.
10012 (command_loop_1): Use it; inhibit selection update for
10013 handle-select-window too (Bug#8996).
10015 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
10017 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
10019 2012-03-25 Kenichi Handa <handa@m17n.org>
10021 * dispextern.h (struct glyph): Change the bit length of
10022 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
10024 2012-03-24 Eli Zaretskii <eliz@gnu.org>
10026 * s/ms-w32.h (tzname): Include time.h before redirecting to
10027 _tzname. Fixes the MSVC build. (Bug#9960)
10029 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
10031 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
10034 * xterm.c (XTread_socket): Only modify handling_signal if
10035 !SYNC_INPUT. (Bug#11080)
10037 2012-03-23 Eli Zaretskii <eliz@gnu.org>
10039 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
10040 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
10041 when fetching a multibyte character consumes more bytes than
10042 CHAR_BYTES returns, due to unification of CJK characters in
10043 string_char. (Bug#11073)
10045 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
10047 * process.c (wait_reading_process_output): Handle pty disconnect
10048 by refraining from sending oneself a SIGCHLD (bug#10933).
10050 2012-03-22 Chong Yidong <cyd@gnu.org>
10052 * dispextern.h (struct it): New member string_from_prefix_prop_p.
10054 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
10055 Mark string as coming from a prefix property.
10056 (handle_face_prop): Use default face for prefix strings (Bug#4281).
10057 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
10059 2012-03-21 Chong Yidong <cyd@gnu.org>
10061 * xfaces.c (Vface_remapping_alist): Doc fix.
10063 2012-03-20 Eli Zaretskii <eliz@gnu.org>
10065 * w32proc.c (Fw32_set_console_codepage)
10066 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
10069 2012-03-20 Chong Yidong <cyd@gnu.org>
10071 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
10072 to reflect default non-nil value of redisplay-dont-pause.
10074 2012-03-19 Kenichi Handa <handa@m17n.org>
10076 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
10077 it fit in a valid range (Bug#11003).
10079 2012-03-18 Eli Zaretskii <eliz@gnu.org>
10081 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
10082 that is not from display property, accept the row as a "cursor
10083 row" if one of the string's character has a non-nil `cursor'
10084 property. Fixes cursor positioning when there are newlines in
10085 overlay strings, e.g. in icomplete.el. (Bug#11035)
10087 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
10089 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
10091 2012-03-12 Chong Yidong <cyd@gnu.org>
10093 * eval.c (inhibit_lisp_code): Rename from
10094 inhibit_window_configuration_change_hook; move from window.c.
10096 * xfns.c (unwind_create_frame_1, Fx_create_frame):
10097 * window.c (run_window_configuration_change_hook)
10098 (syms_of_window): Callers changed.
10100 2012-03-11 Chong Yidong <cyd@gnu.org>
10102 * keymap.c (Fkey_description): Doc fix (Bug#9700).
10104 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
10106 2012-03-10 Chong Yidong <cyd@gnu.org>
10108 * frame.c (other_visible_frames): Don't assume the selected frame
10109 is visible (Bug#10955).
10111 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
10113 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
10115 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
10117 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
10118 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
10121 2012-03-03 Glenn Morris <rgm@gnu.org>
10123 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
10125 2012-03-02 Eli Zaretskii <eliz@gnu.org>
10127 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
10128 position past the first glyph_row that ends at ZV. (Bug#10902)
10129 (redisplay_window, next_element_from_string): Fix typos in
10131 (redisplay_window): Pass to move_it_vertically the margin in
10132 pixels, not in screen lines.
10134 2012-03-02 Glenn Morris <rgm@gnu.org>
10136 * buffer.c (buffer-list-update-hook): Doc fix.
10138 2012-02-29 Eli Zaretskii <eliz@gnu.org>
10140 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
10141 push_it before setting up the iterator for the first overlay
10142 string, even if we have an empty string loaded.
10143 (next_overlay_string): If there's an empty string on the iterator
10144 stack, pop the stack. (Bug#10903)
10146 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
10148 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
10149 Suggested by Stefan Monnier in
10150 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
10151 * alloc.c (widen_to_Lisp_Object): New static function.
10152 (mark_memory): Also mark Lisp_Objects by fetching pointer words
10153 and widening them to Lisp_Objects. This would work even if
10154 USE_LSB_TAG is defined and wide integers are used, which might
10155 happen in a future version of Emacs.
10157 2012-02-25 Chong Yidong <cyd@gnu.org>
10159 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
10162 * xselect.c (Fx_selection_exists_p): Doc fix.
10163 (x_clipboard_manager_save_all): Print an informative message
10164 before saving to clipboard manager.
10166 2012-02-24 Chong Yidong <cyd@gnu.org>
10168 * keyboard.c (process_special_events): Handle all X selection
10169 requests in kbd_buffer, not just the next one (Bug#8869).
10171 2012-02-23 Chong Yidong <cyd@gnu.org>
10173 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
10174 call when setting menu-bar-lines and tool-bar-lines parameters.
10175 (unwind_create_frame_1): New helper function.
10177 * window.c (inhibit_window_configuration_change_hook): New var.
10178 (run_window_configuration_change_hook): Obey it.
10179 (syms_of_window): Initialize it.
10181 2012-02-22 Chong Yidong <cyd@gnu.org>
10183 * xterm.c (x_draw_image_relief): Add missing type check for
10184 Vtool_bar_button_margin (Bug#10743).
10186 2012-02-21 Chong Yidong <cyd@gnu.org>
10188 * fileio.c (Vfile_name_handler_alist): Doc fix.
10190 * buffer.c (Fget_file_buffer): Protect against invalid file
10191 handler return value.
10193 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
10195 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
10196 when computing $valmask.
10198 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
10199 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
10200 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
10201 It's useless in that case, and it can cause problems on hosts
10202 that allocate halves of EMACS_INT values separately.
10203 Reported by Dan Horák. Diagnosed by Andreas Schwab in
10204 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
10205 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
10206 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
10207 it avoids undefined behavior on hosts where shifting right by more
10208 than the word width has undefined behavior.
10210 2012-02-19 Chong Yidong <cyd@gnu.org>
10212 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
10213 (Funhandled_file_name_directory, Ffile_name_as_directory)
10214 (Fdirectory_file_name, Fexpand_file_name)
10215 (Fsubstitute_in_file_name): Protect against invalid file handler
10216 return values (Bug#10845).
10218 2012-02-18 Eli Zaretskii <eliz@gnu.org>
10220 * .gdbinit (pitx): Fix incorrect references to fields of the
10223 2012-02-17 Chong Yidong <cyd@gnu.org>
10225 * syntax.c (Fscan_lists): Doc fix (Bug#10833).
10227 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>
10229 * image.c (MAX_IMAGE_SIZE): Increase from 6.0 to 10.0; see
10230 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
10232 2012-02-15 Chong Yidong <cyd@gnu.org>
10234 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
10235 marked as special. Also, starting docstrings with * is obsolete.
10237 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
10239 * gnutls.c (emacs_gnutls_write): Fix last change.
10241 2012-02-13 Lars Ingebrigtsen <larsi@gnus.org>
10243 * gnutls.c (emacs_gnutls_write): Set errno appropriately for
10246 2012-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
10248 * keymap.c (Fsingle_key_description): Handle char ranges.
10250 2012-02-12 Chong Yidong <cyd@gnu.org>
10252 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
10253 as that creates a dangerous corner case.
10255 * window.c (Fdelete_window_internal): Invalidate the mouse
10256 highlight (Bug#9904).
10258 2012-02-12 Glenn Morris <rgm@gnu.org>
10260 * xselect.c (Fx_own_selection_internal)
10261 (Fx_get_selection_internal, Fx_disown_selection_internal)
10262 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
10263 * nsselect.m (Fx_own_selection_internal)
10264 (Fx_disown_selection_internal, Fx_selection_exists_p)
10265 (Fx_selection_owner_p, Fx_get_selection_internal):
10266 Sync docs and argument specs with the xselect.c versions.
10268 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>

10815 cases where the *-change-functions have already been properly called
10818 2011-12-01 Andreas Schwab <schwab@linux-m68k.org>
10820 * keyboard.c (interrupt_signal): Don't call kill-emacs when

10825 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
10826 verifies glyph row's hash code--we have just reallocated the
10827 glyphs, so their contents can be complete garbage. (Bug#10164)

10991 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
10992 is set, removing the need for VIRT_ADDRESS_VARIES.
10993 (PURE_P): Use a more-efficient implementation that needs just one
10994 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
10995 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
10996 to 4 (xorl, subq, cmpq, setbe).
10997 * alloc.c (pure): Always extern now, since that's the

11000 consistency with the new puresize.h.
11001 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
11002 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

11008 (erase_phys_cursor, update_window_cursor, show_mouse_face)
11009 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
11010 behave as if the cursor position were at the window margin.
11012 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
11013 and the cursor position is out of bounds, behave as if the cursor
11014 position were at the window margin. (Bug#10075)
11016 2011-11-18 Chong Yidong <cyd@gnu.org>
11018 * window.c (Fwindow_combination_limit): Make first argument

11037 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
11039 * xdisp.c (row_hash): New function, body extracted from
11040 compute_line_metrics.
11041 (compute_line_metrics): Call row_hash, instead of computing the
11044 * dispnew.c (verify_row_hash): Call row_hash for computing the
11045 hash code of a row, instead of duplicating code from xdisp.c.
11047 * dispextern.h (row_hash): Add prototype.
11049 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
11051 * frame.c (delete_frame): Don't delete the terminal when the last

11087 * xdisp.c (display_line): Move the call to
11088 highlight_trailing_whitespace before the call to
11089 compute_line_metrics, since the latter needs to see the final
11090 faces of all the glyphs to compute ROW's hash value.

11100 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
11101 with user-defined heap size. Bump the default size of the temacs

11105 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
11106 current_matrix and desired_matrix. (Bug#9990)
11107 (verify_row_hash) [XASSERTS]: New function.

11154 Avoid some portability problems by eschewing 'extern inline' functions.
11155 The trivial performance wins aren't worth the portability hassles; see
11156 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
11158 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

11224 * xmenu.c (cleanup_widget_value_tree): New function.
11225 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
11226 calling free_menubar_widget_value_tree directly (Bug#9830).
11228 2011-11-06 Paul Eggert <eggert@cs.ucla.edu>
11230 Fix some portability problems with 'inline'.
11231 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
11232 (window_box_width, window_box_left, window_box_left_offset)
11233 (window_box_right, window_box_right_offset): Declare extern.
11234 Otherwise, these inline functions do not conform to C99 and
11235 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
11236 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
11237 * intervals.c (adjust_intervals_for_insertion)
11238 (adjust_intervals_for_deletion): Now extern, because otherwise the
11239 extern inline functions 'offset_intervals' couldn't refer to it.
11240 (static_offset_intervals): Remove.
11241 (offset_intervals): Rewrite using the old contents of
11242 static_offset_intervals. The old version didn't conform to C99
11243 because an extern inline function contained a reference to an
11244 identifier with static linkage.
11246 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
11248 * keyboard.c (interrupt_signal): Don't call kill-emacs while in

11266 (Fwindow_vscroll): Doc fix.
11267 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
11268 argument, since it makes no sense to pass a live window and for
11269 consistency with window-child.

11310 official. Move initialization of image_cache_refcount and
11311 dpyinfo_refcount before calling init_frame_faces (Bug#9943).

11351 previous/next-single-property-change returns nil, treat that as
11352 the beginning or the end of the buffer. (Bug#9955)
11354 2011-11-04 Jan Djärv <jan.h.d@swipnet.se>
11356 * gtkutil.c (xg_make_tool_item): Add callbacks if one of wimage or

11479 (w32font_open_internal, compute_metrics):
11480 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
11481 instead of calling the "wide" APIs directly.
11483 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
11485 * w32.h (syms_of_w32font): Add prototype.

11494 2011-10-27 Chong Yidong <cyd@gnu.org>
11496 * process.c (make_process): Set gnutls_state to NULL.
11498 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
11499 non-NULL, regardless of GNUTLS_INITSTAGE.

11548 (bidi_resolve_weak): Don't enter the expensive loop if the current
11549 position is before next_en_pos. Record the bidi type of the first
11550 non-ET, non-BN character we find, in addition to its position.
11551 (bidi_level_of_next_char): Invalidate next_en_type when
11552 next_en_pos is over-stepped.
11554 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
11556 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
11557 * editfns.c: Rewrite current-time-zone so that it invokes
11558 the equivalent of (format-time-string "%Z") to get the time zone name.
11559 This fixes a bug when the time zone name contains characters that
11560 need converting from the system time locale to Emacs internal format.
11561 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
11562 that patch fixed format-time-string to do the conversion, but
11563 I forgot to fix current-time-zone.
11564 (format_time_string): New function, containing most of
11565 what Fformat_time_string used to contain.
11566 (Fformat_time_string): Rewrite in terms of format_time_string.
11567 This doesn't change this function's behavior.
11568 (current-time-zone): Rewrite to use format_time_string.
11569 This fixes the bug reported by Michael Schierl in
11570 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
11571 Jason Rumney's 2007-06-07 change worked around this bug, but
11573 * systime.h (tzname, timezone): Remove no-longer-used declarations.
11575 2011-10-19 Eli Zaretskii <eliz@gnu.org>
11577 * xdisp.c (start_display): If the character at POS is displayed
11578 via a display vector, reset IT->current.dpvec_index to zero.
11579 (try_window_reusing_current_matrix): If a line ends in a display
11580 vector or the next line starts in a display vector, continue
11581 redrawing the window even though the character position of
11582 start_row was reached.
11585 2011-10-18 Chong Yidong <cyd@gnu.org>
11587 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
11588 with nobreak-char-display too.
11590 2011-10-18 Eli Zaretskii <eliz@gnu.org>
11592 Fix part 3 of bug#9771.
11593 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
11594 (bidi_resolve_neutral): Don't enter the expensive loop looking for
11595 non-neutral characters if the current character is a paragraph
11596 separator (a.k.a. Newline). This avoids running the same
11597 expensive loop twice, once when we consume the preceding newline
11598 and the other time when the line actually needs to be displayed.
11599 Avoid the loop when we see neutrals on the base embedding level
11600 following a character whose directionality is the same as the
11601 paragraph's. This avoids running the expensive loop when a line
11602 ends in a long sequence of neutrals, like control characters.
11603 Add assertion against STRONG_AL type. Slightly rearrange code
11604 that determines the type of a neutral given the first non-neutral
11606 (bidi_level_of_next_char): Set next_en_pos to zero when
11607 invalidating its info.
11609 2011-10-17 Eli Zaretskii <eliz@gnu.org>
11611 * xdisp.c (push_display_prop): Determine whether to record string
11612 or buffer position by IT->string, not by IT->method. Allow
11613 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
11614 (move_it_vertically_backward): Don't look for character position
11615 immediately after the newline when in a continuation line.
11618 2011-10-15 Martin Rudalics <rudalics@gmx.at>
11620 * window.c (coordinates_in_window): Rewrite and delabelize
11621 vertical border check. (Bug#5357) (Bug#9618)

11628 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
11630 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
11631 avoid crash when xmalloc overrun checking is enabled.
11633 2011-10-13 Eli Zaretskii <eliz@gnu.org>
11635 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
11636 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
11637 cursor motion with <left> and <right> arrow keys.
11639 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
11640 some callers set that themselves.
11642 2011-10-12 Eli Zaretskii <eliz@gnu.org>
11644 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
11645 display string and the previous row comes from the same string and
11646 is empty. (Bug#9739) (Bug#9738)
11648 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
11650 * doc.c (get_doc_string): Encode file name (bug#9735).

11654 * bidi.c (bidi_level_of_next_char):
11655 * xdisp.c (get_visually_first_element): Remove old incorrect
11656 comments regarding the Unicode Line Separator character.
11658 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.

11666 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
11668 * xdisp.c (set_cursor_from_row): Simplify conditionals,
11669 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
11671 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
11672 Some packages use them to denote characters with modifiers.
11674 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
11676 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
11677 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
11678 matching a pp-number. Rename parameter var to var1.
11680 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
11682 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
11684 2011-10-08 Glenn Morris <rgm@gnu.org>
11686 * callint.c (Fcall_interactively): Give a more explicit error for the
11687 'c' case with a non-character input. (Bug#8479)
11689 2011-10-08 Eli Zaretskii <eliz@gnu.org>
11691 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
11693 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
11694 lines that are hscrolled on the left.
11696 * dispnew.c (buffer_posn_from_coords): Account for a possible
11697 presence of header-line. (Bug#4426)
11699 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
11701 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
11702 Don't advertise functionality which we discourage or doesn't work.
11704 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
11706 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
11707 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
11708 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
11709 this makes Emacs dump core during garbage collection on rare
11710 occasions. sizeof is obviously inferior to offsetof here, so
11711 stick with offsetof.
11712 (GC_POINTER_ALIGNMENT): New macro.
11713 (mark_memory): Omit 3rd (offset) arg; caller changed.
11714 Don't assume EMACS_INT alignment is the same as pointer alignment.
11716 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
11718 * keyboard.c (read_key_sequence_remapped): New var.
11719 (read_key_sequence): Compute remapping in the right buffer.
11720 (command_loop_1): Use read_key_sequence's remapping directly.
11722 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
11724 * dired.c (file_name_completion): Don't expand file name.
11725 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
11726 before checking file name handler.
11728 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
11729 they've been requested explicitly (bug#9591).
11731 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
11733 * keymap.c (Fsingle_key_description): Use make_specified_string
11734 instead of build_string to build string from push_key_description.
11737 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
11739 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
11740 This fixes a Y2038 bug on 64-bit hosts.
11741 * buffer.c (reset_buffer):
11742 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
11743 (Fclear_buffer_auto_save_failure):
11744 Use 0, not -1, to represent an unset failure time, since time_t
11745 might not be signed.
11747 Remove dependency on glibc malloc internals.
11748 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11749 Move back here from lisp.h, but with their new implementations.
11750 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
11751 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
11752 * charset.c (charset_table_init): New static var.
11753 (syms_of_charset): Use it instead of xmalloc. This removes a
11754 dependency on glibc malloc internals. See Eli Zaretskii's comment in
11755 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
11756 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11757 Move back to alloc.c.
11758 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
11759 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
11761 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
11763 * nsterm.m (windowDidResize): Call x_set_window_size only when
11764 ns_in_resize is true. Otherwise set pixelwidth/height and
11765 call change_frame_size (Bug#9628).
11767 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
11769 Port --enable-checking=all to Fedora 14 x86-64.
11770 * charset.c (syms_of_charset): Also account for glibc malloc's
11771 internal overhead when calculating the initial malloc maximum.
11773 Port --enable-checking=all to Fedora 14 x86.
11774 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11776 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
11777 (overrun_check_realloc, overrun_check_free):
11778 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
11779 That way, xmalloc returns a properly-aligned pointer even if
11780 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
11781 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
11782 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
11783 into account when calculating the initial malloc maximum.
11784 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11785 Move here from alloc.c, so that charset.c can use it too.
11786 Properly align; the old code wasn't right for common 32-bit hosts
11787 when configured with --enable-checking=all.
11788 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
11789 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
11791 2011-09-29 Eli Zaretskii <eliz@gnu.org>
11793 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
11796 2011-09-28 Eli Zaretskii <eliz@gnu.org>
11798 * xdisp.c (compute_display_string_end): If there's no display
11799 string at CHARPOS, return -1.
11801 * bidi.c (bidi_fetch_char): When compute_display_string_end
11802 returns a negative value, treat the character as a normal
11803 character not covered by a display string. (Bug#9624)
11805 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
11807 * lread.c (Fread_from_string): Fix typo in docstring.
11809 2011-09-27 Eli Zaretskii <eliz@gnu.org>
11811 * xdisp.c (handle_invisible_prop): If invisible text ends on a
11812 newline, reseat the iterator instead of bidi-iterating there one
11813 character at a time. (Bug#9610)
11814 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
11815 TO_CHARPOS if the bidi iterator is at base embedding level.
11817 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
11819 * lread.c (readevalloop): Use correct code for NBSP.
11820 (read1): Likewise. (Bug#9608)
11822 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
11824 * dbusbind.c (Fdbus_register_signal): When service is not
11825 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
11827 2011-09-25 Glenn Morris <rgm@gnu.org>
11829 * buffer.c (truncate-lines): Doc fix.
11831 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
11833 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
11834 (Fset_window_next_buffers): Doc fix.
11836 2011-09-24 Glenn Morris <rgm@gnu.org>
11838 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
11840 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
11842 Fix minor problems found by static checking.
11843 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
11844 * indent.c (Fvertical_motion): Fix == vs = typo.
11846 2011-09-24 Eli Zaretskii <eliz@gnu.org>
11848 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
11849 Default value is now t. Doc fix.
11851 * indent.c (Fvertical_motion): Compute and apply the overshoot
11852 logic when moving up, not only when moving down. Fix the
11853 confusing name and values of the it_overshoot_expected variable;
11854 logic changes accordingly. (Bug#9254) (Bug#9549)
11856 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
11857 CHARPOS is covered by a display string which includes newlines.
11858 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
11859 is covered by a display string with embedded newlines.
11861 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
11863 * dbusbind.c (Fdbus_register_signal): Add match rule to
11864 Vdbus_registered_objects_table. (Bug#9581)
11865 (Fdbus_register_method, Vdbus_registered_objects_table):
11868 2011-09-24 Jim Meyering <meyering@redhat.com>
11870 do not ignore write error for any output size
11871 The previous change was incomplete.
11872 While it makes emacs --batch detect the vast majority of stdout
11873 write failures, errors were still ignored whenever the output size is
11874 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
11875 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
11876 && echo FAIL: ignored write error
11877 FAIL: ignored write error
11878 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
11879 && echo FAIL: ignored write error
11880 FAIL: ignored write error
11881 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
11883 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
11885 * emacs.c (Fkill_emacs): In noninteractive mode exit
11886 non-successfully if a write error occurred on stdout. (Bug#9574)
11888 2011-09-21 Eli Zaretskii <eliz@gnu.org>
11890 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
11893 * dispextern.h (struct it): Update the comment documenting what
11896 2011-09-20 Eli Zaretskii <eliz@gnu.org>
11898 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
11899 a display string, extend search for cursor position to end of row.
11900 (find_row_edges): If the row ends in a newline from a display
11901 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
11902 Handle the case of a display string with multiple newlines.
11903 (Fcurrent_bidi_paragraph_direction): Fix search for previous
11904 non-empty line. Fixes confusing cursor motion with arrow keys at
11905 the beginning of a line that starts with whitespace.
11907 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
11909 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
11912 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
11914 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
11915 boolean (Bug#9154).
11917 2011-09-18 Eli Zaretskii <eliz@gnu.org>
11919 * xdisp.c (display_line): Record maximum and minimum buffer
11920 positions even if no glyphs were produced (e.g., by a zero-width
11921 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
11922 buffer positions that will be removed from the glyph row because
11924 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
11925 column is beyond frame width: don't subtract 1 "pixel" when
11926 computing width of the stretch.
11927 (reseat_at_next_visible_line_start): Undo the change made on
11928 2011-09-17 that saved paragraph information and restored it after
11929 the call to `reseat'. (Bug#9545)
11931 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11933 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
11934 and turn window cursor on if cleared (Bug#9415).
11936 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
11938 * search.c (boyer_moore): Take unibyte characters from pattern
11939 literally. (Bug#9458)
11941 2011-09-18 Eli Zaretskii <eliz@gnu.org>
11943 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
11945 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
11947 Fix minor problem found by static checking.
11948 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
11949 initialized, to pacify gcc -Wuninitialized.
11951 * fileio.c: Report proper errno when syscall falls.
11952 (Finsert_file_contents): Save and restore errno,
11953 so that report_file_error outputs the correct diagnostic.
11954 (Fwrite_region) [CLASH_DETECTION]: Likewise.
11956 2011-09-18 Eli Zaretskii <eliz@gnu.org>
11958 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
11960 2011-09-17 Eli Zaretskii <eliz@gnu.org>
11962 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
11963 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
11965 2011-09-17 Eli Zaretskii <eliz@gnu.org>
11967 * xdisp.c (reseat_at_next_visible_line_start): Keep information
11968 about the current paragraph and restore it after the call to reseat.
11970 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
11971 (bidi_find_paragraph_start): Search back for paragraph beginning
11972 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
11973 (bidi_move_to_visually_next): Only trigger paragraph-related
11974 computations when the last character is a newline or at EOB, not
11975 just any NEUTRAL_B. (Bug#9470)
11977 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
11978 truncated lines if point is covered by a display string. (Bug#9524)
11980 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
11982 * xselect.c: Relax test for outgoing X longs (Bug#9498).
11983 (cons_to_x_long): New function.
11984 (lisp_data_to_selection_data): Use it. Correct the test for
11985 short-versus-long data; it was negated. Break out of vector
11986 loop, for efficiency, when a long datum is discovered.
11988 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
11990 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
11992 2011-09-16 Eli Zaretskii <eliz@gnu.org>
11994 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
11995 GCC PR/17406) by declaring this function with external scope.
11997 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
11999 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
12000 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
12002 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
12004 * editfns.c (Fformat): Correctly handle text properties on "%%".
12006 2011-09-15 Eli Zaretskii <eliz@gnu.org>
12008 * xterm.c (x_draw_composite_glyph_string_foreground):
12009 * w32term.c (x_draw_composite_glyph_string_foreground):
12010 * term.c (encode_terminal_code):
12011 * composite.c (composition_update_it, get_composition_id):
12012 * xdisp.c (get_next_display_element)
12013 (fill_composite_glyph_string): Add comments about special meaning
12014 of TAB characters in a composition.
12016 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
12018 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
12019 This occurs when processing a multibyte format.
12020 Problem reported by Wolfgang Jenker.
12022 2011-09-15 Johan Bockgård <bojohan@gnu.org>
12024 * xdisp.c (try_cursor_movement): Only check for exact match if
12025 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
12027 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
12029 Remove unused external symbols.
12030 * dispextern.h (calc_pixel_width_or_height): Remove decl.
12031 * xdisp.c (calc_pixel_width_or_height): Now static.
12032 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
12033 * indent.c (check_display_width):
12034 * w32term.c: Fix comment to match code.
12035 * xterm.c, xterm.h (x_catching_errors): Remove.
12037 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
12039 * xselect.c: Use signed conversions more consistently (Bug#9498).
12040 (selection_data_to_lisp_data): Assume incoming selection data are
12041 signed integers, not unsigned. This is to be consistent with
12042 outgoing selection data, which was modified to use signed integers
12043 in as part of the fix to Bug#9196 in response to Jan D.'s comment
12044 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
12045 expects long, not unsigned long.
12047 2011-09-14 Eli Zaretskii <eliz@gnu.org>
12049 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
12050 computation of loop end. Reported by Johan Bockgård
12053 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
12055 * frame.c (Fother_visible_frames_p): Function deleted.
12057 2011-09-12 Eli Zaretskii <eliz@gnu.org>
12059 * indent.c (compute_motion): Process display vector front to back
12060 rather than the other way around. (Bug#2496)
12062 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
12064 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
12066 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
12068 * minibuf.c (Fread_from_minibuffer): Doc fix.
12070 2011-09-11 Eli Zaretskii <eliz@gnu.org>
12072 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
12073 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
12075 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
12077 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
12078 value for non-existent files.
12080 2011-09-11 Eli Zaretskii <eliz@gnu.org>
12082 * fileio.c (Finsert_file_contents): If the file cannot be opened,
12083 set its "size" to -1. This will set the modtime_size field of
12084 the corresponding buffer to -1, which is what
12085 verify-visited-file-modtime expects for files that do not exist.
12088 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
12090 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
12092 * lisp.h: ... from here. push_key_description is no longer
12093 defined in keyboard.c, so its declaration should not be in
12094 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
12095 logically belongs with push_key_description.
12097 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
12099 * buffer.h: Include <sys/types.h> instead of <time.h>.
12100 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
12101 Problem reported by Herbert J. Skuhra.
12103 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
12105 * xml.c (parse_region): Make the parsing work for
12106 non-comment-starting XML files again (bug#9144).
12108 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
12110 * image.c (gif_load): Fix calculation of bottom and right corner.
12113 2011-09-10 Eli Zaretskii <eliz@gnu.org>
12115 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
12116 redisplay in small windows.
12118 2011-09-09 Eli Zaretskii <eliz@gnu.org>
12120 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
12122 2011-09-08 Martin Rudalics <rudalics@gmx.at>
12124 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
12125 Operate on live windows only.
12127 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
12129 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
12131 2011-09-07 Eli Zaretskii <eliz@gnu.org>
12133 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
12134 only under bidi iteration.
12136 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
12138 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
12140 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
12142 isnan: Fix porting problem to Solaris 10 with bundled gcc.
12143 Without this fix, the command to link temacs failed due to an
12144 undefined symbol __builtin_isnan. This is because
12145 /usr/include/iso/math_c99.h #defines isnan(x) to
12146 __builtin_isnan(x), but the bundled gcc, which identifies itself
12147 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
12149 * floatfns.c (isnan): #undef, and then #define to a clone of
12151 (Fisnan): Always define, since it's always available now.
12152 (syms_of_floatfns): Always define isnan at the Lisp level.
12154 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
12156 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
12158 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
12160 * fileio.c: Fix bugs with large file offsets (Bug#9428).
12161 The previous code assumed that file offsets (off_t values) fit in
12162 EMACS_INT variables, which is not true on typical 32-bit hosts.
12163 The code messed up by falsely reporting buffer overflow in cases
12164 such as (insert-file-contents "big" nil 1 2) into an empty buffer
12165 when "big" contains more than 2**29 bytes, even though this
12166 inserts just one byte and does not overflow the buffer.
12167 (Finsert_file_contents): Store file offsets as off_t
12168 values, not as EMACS_INT values. Check for overflow when
12169 converting between EMACS_INT and off_t. When checking for
12170 buffer overflow or for overlap, take the offsets into account.
12171 Don't use EMACS_INT for small values where int suffices.
12172 When checking for overlap, fix a typo: ZV was used where
12173 ZV_BYTE was intended.
12174 (Fwrite_region): Don't assume off_t fits into 'long'.
12175 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
12177 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
12179 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
12181 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
12183 sprintf-related integer and memory overflow issues (Bug#9412).
12185 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
12186 (esprintf, exprintf, evxprintf): New functions.
12187 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
12188 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
12189 (modify_event_symbol): Do not assume that the length of
12190 name_alist_or_stem is safe to alloca and fits in int.
12191 (Fexecute_extended_command): Likewise for function name and binding.
12192 (Frecursion_depth): Wrap around reliably on integer overflow.
12193 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
12194 since some callers pass EMACS_INT values.
12195 (Fsingle_key_description): Don't crash if symbol name contains more
12196 than MAX_ALLOCA bytes.
12197 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
12198 (get_minibuffer): Arg is now EMACS_INT, not int.
12199 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
12200 (esprintf, exprintf, evxprintf): New decls.
12201 * window.h (command_loop_level, minibuf_level): Reflect API changes.
12203 * dbusbind.c (signature_cat): New function.
12204 (xd_signature, Fdbus_register_signal):
12205 Do not overrun buffer; instead, report string overflow.
12207 * dispnew.c (add_window_display_history): Don't overrun buffer.
12208 Truncate instead; this is OK since it's just a log.
12210 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
12211 even if the time zone offset is outlandishly large.
12212 Don't mishandle offset == INT_MIN.
12214 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
12215 when creating daemon; the previous buffer-overflow check was incorrect.
12217 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
12218 which has the guts of the old verror function.
12220 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
12221 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
12223 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
12224 (font_unparse_xlfd): Don't blindly alloca long strings.
12225 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
12226 fits in int, when using sprintf. Use single snprintf to count
12227 length of string rather than counting it via multiple sprintfs;
12228 that's simpler and more reliable.
12229 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
12230 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
12231 sprintf, in case result does not fit in int.
12233 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
12234 (fontset_from_font): Print it.
12236 * frame.c (tty_frame_count): Now printmax_t, not int.
12237 (make_terminal_frame, set_term_frame_name): Print it.
12238 (x_report_frame_params): In X, window IDs are unsigned long,
12239 not signed long, so print them as unsigned.
12240 (validate_x_resource_name): Check for implausibly long names,
12241 and don't assume name length fits in 'int'.
12242 (x_get_resource_string): Don't blindly alloca invocation name;
12243 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
12246 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
12247 (xg_check_special_colors, xg_set_geometry):
12248 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
12250 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
12251 Use esprintf, not sprintf, in case result does not fit in int.
12253 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
12254 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
12255 it as a large positive number.
12256 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
12257 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
12259 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
12260 in case result does not fit in int.
12262 * print.c (float_to_string): Detect width overflow more reliably.
12263 (print_object): Make sprintf buffer a bit bigger, to avoid potential
12264 buffer overrun. Don't assume list length fits in 'int'. Treat
12265 print length of 0 as 0, not as infinity; to be consistent with other
12266 uses of print length in this function. Don't overflow print length
12267 index. Don't assume hash table size fits in 'long', or that
12268 vectorlike size fits in 'unsigned long'.
12270 * process.c (make_process): Use printmax_t, not int, to format
12271 process-name gensyms.
12273 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
12275 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
12276 to avoid potential buffer overrun.
12278 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
12279 if X resource line is longer than 512 bytes.
12281 * xfns.c (x_window): Make sprintf buffer a bit bigger
12282 to avoid potential buffer overrun.
12284 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
12286 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
12288 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
12290 Integer overflow fixes for scrolling, etc.
12291 Without these, Emacs silently mishandles large integers sometimes.
12292 For example, "C-u 4294967297 M-x recenter" was treated as if
12293 it were "C-u 1 M-x recenter" on a typical 64-bit host.
12295 * xdisp.c (try_window_id): Check Emacs fixnum range before
12296 converting to 'int'.
12298 * window.c (window_scroll_line_based, Frecenter):
12299 Check that an Emacs fixnum is in range before assigning it to 'int'.
12300 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
12301 values converted from Emacs fixnums.
12302 (Frecenter): Don't wrap around a line count if it is out of 'int'
12303 range; instead, treat it as an extreme value.
12304 (Fset_window_configuration, compare_window_configurations):
12305 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
12307 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
12308 that can exceed INT_MAX. Check that EMACS_INT value is in range
12309 before assigning it to the (possibly-narrower) index.
12310 (match_limit): Don't assume that a fixnum can fit in 'int'.
12312 * print.c (print_object): Use ptrdiff_t, not int, for index that can
12315 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
12316 (Fvertical_motion): Don't wrap around LINES values that don't fit
12317 in 'int'. Instead, treat them as extreme values. This is good
12318 enough for windows, which can't have more than INT_MAX lines anyway.
12320 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
12322 * Require libxml/parser.h to avoid compilation warning.
12324 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
12326 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
12327 since this reportedly can destroy thread storage.
12329 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
12331 * syntax.c (find_defun_start): Update all cache variables if
12332 exiting early (Bug#9401).
12334 2011-08-30 Eli Zaretskii <eliz@gnu.org>
12336 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
12338 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
12339 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
12340 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
12342 * term.c (tty_append_glyph): New function.
12343 (produce_stretch_glyph): Static function and its prototype deleted.
12345 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
12348 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
12350 * image.c (parse_image_spec): Check for nonnegative, not for positive,
12351 when checking :margin (Bug#9390).
12352 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
12353 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
12354 so that the name doesn't mislead. All uses changed.
12356 2011-08-28 Johan Bockgård <bojohan@gnu.org>
12358 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
12361 2011-08-27 Eli Zaretskii <eliz@gnu.org>
12363 * xdisp.c (move_it_to): Don't bail out early when reaching
12364 position beyond to_charpos, if we are scanning backwards.
12365 (move_it_vertically_backward): When DY == 0, make sure we get to
12366 the first character in the line after the newline.
12368 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
12370 * ccl.c: Improve and simplify overflow checking (Bug#9196).
12371 (ccl_driver): Do not generate an out-of-range pointer.
12372 (Fccl_execute_on_string): Remove unnecessary check for
12373 integer overflow, noted by Stefan Monnier in
12374 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
12375 Remove a FIXME that didn't need fixing.
12376 Simplify the newly-introduced buffer reallocation code.
12378 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
12380 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
12382 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
12384 Integer and memory overflow issues (Bug#9196).
12386 * doc.c (get_doc_string): Rework so that
12387 get_doc_string_buffer_size is the actual buffer size, rather than
12388 being 1 less than the actual buffer size; this makes xpalloc more
12391 * image.c (x_allocate_bitmap_record, cache_image):
12392 * xselect.c (Fx_register_dnd_atom):
12393 Simplify previous changes by using xpalloc.
12395 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
12396 since either will do and ptrdiff_t is convenient with xpalloc.
12398 * charset.c (charset_table_size)
12399 (struct charset_sort_data.priority): Now ptrdiff_t.
12400 (charset_compare): Don't overflow if priorities differ greatly.
12401 (Fsort_charsets): Don't assume list length fits in int.
12402 Check for size-calculation overflow when allocating sort data.
12403 (syms_of_charset): Allocate an initial charset table that is
12404 just under 64 KiB, to avoid problems with glibc malloc and mmap.
12406 * cmds.c (internal_self_insert): Check for size-calculation overflow.
12408 * composite.h (struct composition.glyph_len): Now int, not unsigned.
12409 The actual value is always <= INT_MAX, and leaving it unsigned made
12410 overflow checking harder.
12412 * dispextern.h (struct glyph_matrix.rows_allocated)
12413 (struct face_cache.size): Now ptrdiff_t, for convenience in use
12414 with xpalloc. The values are still always <= INT_MAX.
12416 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
12418 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
12419 (SAFE_NALLOCA): New macro.
12421 * region-cache.c (struct boundary.pos, find_cache_boundary)
12422 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
12423 (set_cache_region, invalidate_region_cache)
12424 (revalidate_region_cache, know_region_cache, region_cache_forward)
12425 (region_cache_backward, pp_cache):
12426 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
12427 so that ptrdiff_t * can be passed to xpalloc.
12428 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
12429 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
12430 (pp_cache): Don't assume cache_len fits in int.
12431 * region-cache.h: Adjust extern decls to match.
12433 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
12434 EMACS_INT, since either will do, for xpalloc.
12436 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
12437 (xnmalloc, xnrealloc, xpalloc): New functions.
12439 * bidi.c (bidi_shelve_header_size): New constant.
12440 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
12441 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
12443 * bidi.c (bidi_cache_shrink):
12444 * buffer.c (overlays_at, overlays_in, record_overlay_string)
12446 Don't update size of array until after memory allocation succeeds,
12447 because xmalloc/xrealloc may not return.
12448 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
12449 now that we have proper integer overflow checking.
12450 (record_overlay_string, overlay_strings): Catch overflows when
12451 calculating size of overlay_str_buf.
12453 * callproc.c (Fcall_process): Check for size overflow when
12454 calculating size of args2.
12455 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
12456 Normally we prefer signed values, but sticking with ptrdiff_t would
12457 require adding more-complicated checks.
12459 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
12460 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
12461 Redo buffer-overflow calculations to avoid integer overflow.
12462 Add a FIXME comment where memory seems to be over-allocated.
12464 * character.c (Fstring): Check for size-calculation overflow.
12466 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
12467 unnecessary integer overflow. Check for size overflow.
12468 (encode_coding_object): Don't update size until xmalloc succeeds.
12470 * composite.c (get_composition_id): Check for overflow in glyph
12471 length calculations.
12473 Integer and memory overflow fixes for display code.
12474 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
12475 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
12476 (scrolling_window): Check for overflow in size calculations.
12477 (line_draw_cost, realloc_glyph_pool, add_row_entry):
12478 Don't assume glyph table len fits in int.

12480 (row_table_size): Now ptrdiff_t, not int.
12481 (scrolling_window): Avoid overflow in size calculations.
12482 Don't update size until allocation succeeds.
12483 * fns.c (concat): Check for overflow in size calculations.
12484 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
12485 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
12486 (NEXT_ALMOST_PRIME_LIMIT): New constant.
12488 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
12489 (get_doc_string): Check for size calculation overflow.
12490 Don't update size until allocation succeeds.
12491 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
12492 EMACS_INT, where ptrdiff_t will do.
12493 (Fsubstitute_command_keys): Check for string overflow.
12495 * editfns.c (set_time_zone_rule): Don't assume environment length
12497 (message_length): Now ptrdiff_t, not int.
12498 (Fmessage_box): Don't update size until allocation succeeds.
12499 Don't assume message length fits in int.
12500 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
12502 * emacs.c (main): Do not reallocate argv, since there is a null at
12503 the end that can be overwritten, and this way there's no need to
12504 worry about size-calculation overflow.
12505 (sort_args): Check for size-calculation overflow.
12507 * eval.c (init_eval_once, grow_specpdl): Don't update size until
12509 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
12511 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
12512 (x_set_scroll_bar_width, x_figure_window_size):
12513 Check for integer overflow.
12514 (x_set_alpha): Do not assume XINT fits in int.
12516 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
12517 This is for the members text_lines, text_cols, total_lines, total_cols,
12518 where the system imposes an 'int' limit.
12520 * fringe.c (Fdefine_fringe_bitmap):
12521 Don't update size until alloc works.
12523 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
12524 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
12526 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
12527 Check for size-calculation overflow.
12528 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
12529 do, as we prefer signed integers.
12530 (id_to_widget.max_size, id_to_widget.used)
12531 (xg_store_widget_in_map, xg_remove_widget_from_map)
12532 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
12533 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
12534 Use and return ptrdiff_t, not int.
12535 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
12536 * gtkutil.h: Change prototypes to match the above.
12538 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
12539 are duplicate now that they've been promoted to lisp.h.
12540 (x_allocate_bitmap_record, x_alloc_image_color)
12541 (make_image_cache, cache_image, xpm_load):
12542 Don't update size until alloc is done.
12543 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
12545 Check for size calculation overflow.
12546 (ct_colors_allocated_max): New constant.
12547 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid
12550 * keyboard.c (read_char, menu_bar_items, tool_bar_items)
12551 (read_char_x_menu_prompt, read_char_minibuf_menu_width)
12552 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
12553 Use ptrdiff_t, not int, to count maps.
12554 (read_char_minibuf_menu_prompt): Check for overflow in size
12555 calculations. Don't update size until allocation succeeds.
12556 Redo calculations to avoid overflow.
12557 * keyboard.h: Change prototypes to match the above.
12559 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
12561 (current_minor_maps): Check for size calculation overflow.
12562 * keymap.h: Change prototypes to match the above.
12564 * lread.c (read1, init_obarray): Don't update size until alloc done.
12566 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.
12567 (store_kbd_macro_char): Reorder multiplicands to avoid overflow.
12569 * nsterm.h (struct ns_color_table.size, struct ns_color_table.avail):
12570 Now ptrdiff_t, not int.

12583 (Fset_match_data): Don't assume list lengths fit in 'int'.
12585 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
12586 for command line length. Do not attempt to address one before the
12587 beginning of an array, as that's not portable.
12589 * term.c (max_frame_lines): Remove; unused.

12616 (Finternal_make_lisp_face, cache_face):
12617 Check for size calculation overflow.
12618 (cache_face): Treat size calculation overflows as if they were
12619 memory exhaustion (the usual treatment), rather than aborting.
12621 * xfns.c (x_encode_text, x_set_name_internal)
12622 (Fx_change_window_property): Use ptrdiff_t, not int, to count
12623 sizes, since they can exceed INT_MAX in size. Check for size
12624 calculation overflow.
12626 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
12627 (xg_select): Check for size calculation overflow.
12628 Don't update size until alloc done.
12630 * xrdb.c (get_environ_db): Don't assume path length fits in int,
12631 as sprintf is limited to int lengths.
12633 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
12634 (X_LONG_MIN): New macros.
12635 Use them to make the following changes clearer.
12636 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
12637 This change doesn't affect the value now, but it may help remind
12638 future maintainers not to raise the value too much later.
12639 (SELECTION_QUANTUM): Remove, replacing with ...
12640 (selection_quantum): ... new function, which avoids overflow.
12642 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
12643 assumption that selection length fits in 'int'.
12644 (x_reply_selection_request, x_handle_selection_request)
12645 (x_get_window_property, receive_incremental_selection)

12651 Redo calculations to avoid overflow.
12652 (x_reply_selection_request): When sending hint, ceiling it at

12656 (lisp_data_to_selection_data, x_property_data_to_lisp):
12657 Check for size-calculation overflow.

12660 Don't store size until memory allocation succeeds.
12661 (x_get_window_property): Plug memory leak on memory exhaustion.
12662 Don't double-block input; malloc is safe here. Don't assume 2**34
12663 - 4 fits in unsigned long. Add an xassert to check
12664 XGetWindowProperty overflow. Be more careful about overflow
12665 calculations, and distinguish size from memory overflow better.
12666 (receive_incremental_selection): When tracing, don't assume
12667 unsigned int is less than INT_MAX.
12668 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
12669 harmful) conversions of unsigned short to int.

12671 in the range -65535 through -1 fit in an X unsigned short.
12672 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
12673 result parameters unless successful. Rely on cons_to_unsigned
12674 to report problems with elements; the old code wasn't right anyway.
12675 (x_check_property_data): Check for int overflow; we cannot use
12676 a wider type due to X limits.
12677 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
12679 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.

12709 * lisp.h (hash_lookup, hash_put):
12710 * minibuf.c (Ftest_completion):
12711 Use ptrdiff_t for hash table indexes, not int (which is too
12712 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
12713 32-bit --with-wide-int hosts).
12715 * charset.c (Fdefine_charset_internal): Check for integer overflow.
12716 Add a FIXME comment about memory leaks.
12717 (syms_of_charset): Don't assume xmalloc returns.

12724 with outlandish widths.
12725 * character.h (sanitize_tab_width): Rename from sanitize_width,
12726 now that we have two such functions. All uses changed.

12744 * xterm.c: Don't go over XClientMessageEvent limit.
12745 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
12746 (x_send_scroll_bar_event): Likewise. Check that the size does not
12747 exceed limits imposed by XClientMessageEvent, as well as the usual
12748 ptrdiff_t and size_t limits.
12750 * keyboard.c: Overflow, signedness and related fixes.
12751 (make_lispy_movement): Use same integer type in forward decl
12752 that is used in the definition.
12753 (read_key_sequence, keyremap_step):
12754 Change bufsize argument back to int, undoing my 2011-03-30 change.
12755 We prefer signed types, and int is wide enough here.
12756 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
12757 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
12758 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
12759 length, not size_t. Use ptrdiff_t for index, not int.
12760 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
12761 possibility of integer overflow.
12763 Overflow, signedness and related fixes for images.

12785 (lookup_image): Remove unnecessary tests.
12786 (xbm_image_p): Locals are now of int, not EMACS_INT,
12787 since parse_image_check makes sure they fit into int.
12788 (png_load, gif_load, svg_load_image):
12789 Prefer int to unsigned where either will do.
12790 (tiff_handler): New function, combining the cores of the
12791 old tiff_error_handler and tiff_warning_handler.
12792 This function is rewritten to use vsnprintf and thereby avoid
12793 stack buffer overflows. It uses only the features of vsnprintf
12794 that are common to both POSIX and native Microsoft.
12795 (tiff_error_handler, tiff_warning_handler): Use it.
12796 (tiff_load, gif_load, imagemagick_load_image):
12797 Don't assume :index value fits in 'int'.
12798 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
12799 (imagemagick_load_image): Check that crop parameters fit into
12800 the integer types that MagickCropImage accepts. Don't assume
12801 Vimagemagick_render_type has a nonnegative value. Don't assume
12802 size_t fits in 'long'.
12803 (gs_load): Use printmax_t to print the widest integers possible.
12804 Check for integer overflow when computing image height and width.

12816 handle_single_display_spec, not just 1 or zero.
12817 (handle_single_display_spec): If the display spec is of the form
12818 `(space ...)', and specifies display in the text area, return 2
12820 (try_cursor_movement): Check for the need to scroll more
12821 accurately, and prefer exact match for point under bidi.
12822 Don't advance `row' beyond the last row of the window.

12840 buffers, return left-to-right.
12841 (set_cursor_from_row): Consider candidate row a win if its glyph
12842 represents a newline and point is on that newline. Fixes cursor
12843 positioning on the newline at EOL of R2L text within L2R
12844 paragraph, and vice versa.
12845 (try_cursor_movement): Check continued rows, in addition to
12846 continuation rows. Fixes unwarranted scroll when point enters a
12847 continued line of R2L text within an L2R paragraph, or vice versa.
12848 (cursor_row_p): Consider the case of point being equal to
12849 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
12850 from the end of a short line to the beginning of a continued line
12851 of R2L text within L2R paragraph.

12878 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
12879 instead of CHAR_TO_BYTE. Fixes a crash when a completion
12880 candidate is selected by the mouse, and that candidate has a
12881 composed character under the mouse.
12883 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
12884 coordinates reported by pos-visible-in-window-p for a composed
12885 character in column zero.
12887 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>

12893 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
12894 consider it a hit if to_charpos is anywhere in the range of the
12895 composed buffer positions.
12897 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
12899 * image.c (gif_load): Don't assume that each subimage has the same
12900 dimensions as the base image. Handle disposal method that is
12901 "undefined" by the gif spec (Bug#9335).
12903 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
12905 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

12915 a composition, take its buffer position from IT->cmp_it.charpos.
12916 Fixes cursor positioning at the beginning of a line that begins
12917 with a composed character.
12919 2011-08-18 Eli Zaretskii <eliz@gnu.org>
12921 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
12922 character bidirectional type, use STRONG_L instead. Fixes crashes
12923 in a buffer produced by `describe-categories'.
12925 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
12926 members before the level stack, so they would be saved and
12927 restored when copying iterator state. Fixes incorrect reordering
12928 around TABs covered by display properties.
12930 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>

12956 Fix memory allocation problems in Cygwin build (Bug#9273).
12958 * unexcw.c ( __malloc_initialized): Declare external variable.
12959 (fixup_executable): Force the dumped emacs to reinitialize malloc.
12961 * gmalloc.c [CYGWIN] (bss_sbrk_heapbase, bss_sbrk_heapinfo):

13002 * xdisp.c (move_it_in_display_line_to): Don't invoke
13003 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
13004 ppos_it. Fixes vertical cursor motion when line beginning is
13005 covered by an image. (Bug#9296)

13015 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
13016 the event loop. Get status from as_status (Bug#7276).
13018 * nsterm.m (sendEvent): If event is NSApplicationDefined and
13019 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
13020 the event loop (Bug#7276).
13022 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
13024 * gnutls.c (QCgnutls_bootprop_priority)
13025 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
13026 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
13027 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
13028 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
13029 (QCgnutls_bootprop_verify_hostname_error)
13030 (QCgnutls_bootprop_callbacks_verify): Rename from
13031 Qgnutls_bootprop_..., all uses changed.
13033 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
13036 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
13038 * xfaces.c (Qframe_set_background_mode): Now static.
13039 * dispextern.h (Qframe_set_background_mode): Remove decl.
13041 * process.c (Fnetwork_interface_info): Declare local only if needed.
13043 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
13045 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
13046 (Fnetwork_interface_list): Allocate in increments of bytes instead
13047 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
13048 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
13050 (struct ifflag_def): notrailers is smart on OSX.
13051 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
13052 Get hardware address with getifaddrs if available.
13054 2011-08-12 Eli Zaretskii <eliz@gnu.org>
13056 * xdisp.c (iterate_out_of_display_property): xassert that
13057 IT->position is set to within IT->object's boundaries. Break from
13058 the loop as soon as EOB is reached; avoids infloops in redisplay
13059 when IT->position is set up wrongly due to some bug.
13060 Set IT->current to match the bidi iterator unconditionally.
13061 (push_display_prop): Allow GET_FROM_STRING as IT->method on
13062 entry. Force push_it to save on the stack the current
13063 buffer/string position, to be restored by pop_it. Fix flags in
13064 the iterator structure wrt the object coming from a display
13065 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
13066 properties. (Bug#9284)
13068 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
13070 * fontset.c (fontset_get_font_group): Add proper type checks.
13073 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
13075 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
13076 and LC_VERSION_MIN_MACOSX.
13077 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
13078 (dump_it) [LC_FUNCTION_STARTS]: Use it.
13080 2011-08-08 Eli Zaretskii <eliz@gnu.org>
13082 * xdisp.c (forward_to_next_line_start): Allow to use the
13083 no-display-properties-and-no-overlays under bidi display.
13084 Set disp_pos in the bidi iterator to avoid searches for display
13085 properties and overlays.
13087 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
13089 * editfns.c (Fset_time_zone_rule): Document relationship with the
13092 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
13093 the font entity extracted from the cache (Bug#8109).
13095 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
13097 * composite.c (autocmp_chars): Don't reset point. That is done by
13098 restore_point_unwind (Bug#5984).
13100 2011-08-07 Juri Linkov <juri@jurta.org>
13102 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
13103 to show the arg `TIME' instead of `TIMEVAL'.
13105 2011-08-06 Eli Zaretskii <eliz@gnu.org>
13107 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
13108 display property strides EOL and includes a newline, as in
13109 longlines-mode. (Bug#9254)
13110 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
13111 word-wrap under bidirectional display. (Bug#9224)
13113 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
13114 is non-zero, even if the data buffer is NULL. Fixes a crash in
13115 vertical-motion with longlines-mode. (Bug#9254)
13117 2011-08-05 Eli Zaretskii <eliz@gnu.org>
13119 * bidi.c <bidi_cache_total_alloc>: Now static.
13120 (bidi_initialize): Initialize bidi_cache_total_alloc.
13122 * xdisp.c (display_line): Release buffer allocated for shelved bidi
13125 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
13126 amount allocated this far in `bidi_cache_total_alloc'.
13127 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
13128 non-zero, only free the data buffer without restoring the cache
13129 contents. All callers changed.
13131 * dispextern.h (bidi_unshelve_cache): Update prototype.
13133 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
13134 (move_it_in_display_line, move_it_to)
13135 (move_it_vertically_backward, move_it_by_lines): Replace the call
13136 to xfree to an equivalent call to bidi_unshelve_cache.
13137 (move_it_in_display_line_to): Fix logic of returning
13138 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
13140 2011-08-05 Eli Zaretskii <eliz@gnu.org>
13142 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
13143 came from a string character with a `cursor' property. (Bug#9229)
13145 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
13147 * Makefile.in (LIB_PTHREAD): New variable.
13148 (LIBES): Add LIB_PTHREAD (Bug#9216).
13150 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
13151 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
13153 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
13155 * regex.c (re_iswctype): Remove some redundant boolean conversions.
13157 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
13159 * xterm.c (x_find_topmost_parent): New function.
13160 (x_set_frame_alpha): Find topmost parent window with
13161 x_find_topmost_parent and set the property there also (bug#9181).
13162 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
13164 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
13166 * callproc.c (Fcall_process): Avoid vfork clobbering
13167 the local vars buffer, coding_systems, current_dir.
13169 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
13171 * keymap.c (Fmake_composed_keymap): Move to subr.el.
13173 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
13175 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
13176 so that it is not optimized away.
13178 * xdisp.c (compute_display_string_pos): Remove unused local.
13180 2011-08-02 Eli Zaretskii <eliz@gnu.org>
13182 Fix slow cursor motion and scrolling in large buffers with
13183 selective display, like Org Mode buffers. (Bug#9218)
13185 * dispextern.h (struct bidi_it): New member disp_prop_p.
13187 * xdisp.c: Remove one-slot cache of display string positions.
13188 (compute_display_string_pos): Accept an additional argument
13189 DISP_PROP_P; callers changed. Scan at most 5K characters forward
13190 for a display string or property. If found, set DISP_PROP_P
13193 * bidi.c (bidi_fetch_char): Accept an additional argument
13194 DISP_PROP_P, and pass it to compute_display_string_pos.
13195 Only handle text covered by a display string if DISP_PROP_P is returned
13196 non-zero. All callers of bidi_fetch_char changed.
13198 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
13200 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
13202 2010-12-03 Don March <don@ohspite.net>
13204 * keymap.c (Fdefine_key): Fix non-prefix key error message when
13205 last character M-[char] is translated to ESC [char] (bug#7541).
13207 2011-08-02 Kenichi Handa <handa@m17n.org>
13209 * lisp.h (uniprop_table): Extern it.
13211 * chartab.c (uniprop_table): Make it non-static.
13213 2011-08-01 Eli Zaretskii <eliz@gnu.org>
13215 * xdisp.c (forward_to_next_line_start): Accept additional argument
13216 BIDI_IT_PREV, and store into it the state of the bidi iterator had
13218 (reseat_at_next_visible_line_start): Use the bidi iterator state
13219 returned by forward_to_next_line_start to restore the state of
13220 it->bidi_it after backing up to previous newline. (Bug#9212)
13222 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
13224 * regex.c (re_comp): Protoize.
13225 (re_exec): Fix return type.
13226 (regexec): Fix type of `ret'. (Bug#9203)
13228 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
13230 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
13231 This is needed if max-image-size is a floating-point number.
13233 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
13235 * print.c (print_object): Print empty symbol as ##.
13237 * lread.c (read1): Read ## as empty symbol.
13239 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
13241 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
13242 setting frame foreground color (Bug#9175).
13243 (x_set_background_color): Likewise.
13245 * nsmenu.m (-setText): Size tooltip dimensions precisely to
13246 contents (Bug#9176).
13247 (EmacsTooltip -init): Remove bezels and add shadows to
13250 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
13251 or scroll bar (Bug#8470).
13253 * nsfont.m (nsfont_open): Remove assignment to voffset and
13254 unnecessary vars hshink, expand, hd, full_height, min_height.
13255 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
13257 * nsterm.h (nsfont_info): Remove voffset field.
13259 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
13261 Implement strike-through and overline on NextStep (Bug#8863).
13263 * nsfont.m (nsfont_open): Use underline position provided by font,
13264 instead of hard-coded value of 2.
13265 (nsfont_draw): Call ns_draw_text_decoration instead.
13267 * nsterm.h: Add declaration for ns_draw_text_decoration.
13269 * nsterm.m (ns_draw_text_decoration): New function for drawing
13270 underline, overline, and strike-through.
13271 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
13272 ns_draw_text_decoration. Change treatment of cursor drawing to
13273 accommodate underlining, etc.
13275 2011-07-28 Eli Zaretskii <eliz@gnu.org>
13277 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
13280 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
13282 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
13283 Without this fix, if a signal arrives just after memory fills up,
13284 'malloc' might be invoked reentrantly.
13286 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
13287 In other words, assume that every image size is allowed, on non-X
13288 hosts. This assumption is probably wrong, but it lets Emacs compile.
13290 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
13292 * regex.c (re_iswctype): Convert return values to boolean.
13294 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
13296 * xdisp.c (compute_display_string_pos): Don't use cached display
13297 string position if the buffer had its restriction changed.
13300 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
13302 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
13304 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
13306 Integer signedness and overflow and related fixes. (Bug#9079)
13308 * bidi.c: Integer size and overflow fixes.
13309 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
13310 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
13311 (bidi_cache_find_level_change, bidi_cache_ensure_space)
13312 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
13313 (bidi_find_other_level_edge):
13314 Use ptrdiff_t instead of EMACS_INT where either will do.
13315 This works better on 32-bit hosts configured --with-wide-int.
13316 (bidi_cache_ensure_space): Check for size-calculation overflow.
13317 Use % rather than repeated addition, for better worst-case speed.
13318 Don't set bidi_cache_size until after xrealloc returns, because it
13320 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
13321 (bidi_cache_ensure_space): Also check that the bidi cache size
13322 does not exceed that of the largest Lisp string or buffer. See Eli
13323 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
13325 * alloc.c (__malloc_size_t): Remove.
13326 All uses replaced by size_t. See Andreas Schwab's note
13327 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
13329 * image.c: Improve checking for integer overflow.
13330 (check_image_size): Assume that f is nonnull, since
13331 it is always nonnull in practice. This is one less thing to
13332 worry about when checking for integer overflow later.
13333 (x_check_image_size): New function, which checks for integer
13334 overflow issues inside X.
13335 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
13336 This removes the need for a memory_full check.
13337 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
13338 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
13339 (xbm_read_bitmap_data): Change locals back to 'int', since
13340 their values must fit in 'int'.
13341 (xpm_load_image, png_load, tiff_load):
13342 Invoke x_create_x_image_and_pixmap earlier,
13343 to avoid much needless work if the image is too large.
13344 (tiff_load): Treat overly large images as if
13345 x_create_x_image_and_pixmap failed, not as malloc failures.
13346 (gs_load): Use x_check_image_size.
13348 * gtkutil.c: Omit integer casts.
13349 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
13350 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
13352 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
13354 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
13355 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
13356 would wrongly return t on a 64-bit host.
13358 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
13359 The plain *_OVERFLOW macros run afoul of GCC bug 49705
13360 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
13361 and therefore cause GCC to emit a bogus diagnostic in some cases.
13363 * image.c: Integer signedness and overflow and related fixes.
13364 This is not an exhaustive set of fixes, but it's time to
13365 record what I've got.
13366 (lookup_pixel_color, check_image_size): Remove redundant decls.
13367 (check_image_size): Don't assume that arbitrary EMACS_INT values
13368 fit in 'int', or that arbitrary 'double' values fit in 'int'.
13369 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
13370 (tiff_load, imagemagick_load_image):
13371 Check for overflow in size calculations.
13372 (x_create_x_image_and_pixmap): Remove unnecessary test for
13373 xmalloc returning NULL; that can't happen.
13374 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
13375 (xpm_color_bucket): Use better integer hashing function.
13376 (xpm_cache_color): Don't possibly over-allocate memory.
13377 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
13378 (gif_memory_source):
13379 Use ptrdiff_t, not int or size_t, to record sizes.
13380 (png_load): Don't assume values greater than 2**31 fit in 'int'.
13381 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
13382 either works, as we prefer signed integers.
13383 (tiff_read_from_memory, tiff_write_from_memory):
13384 Return tsize_t, not size_t, since that's what the TIFF API wants.
13385 (tiff_read_from_memory): Don't fail simply because the read would
13386 go past EOF; instead, return a short read.
13387 (tiff_load): Omit no-longer-needed casts.
13388 (Fimagemagick_types): Don't assume size fits into 'int'.
13390 Improve hashing quality when configured --with-wide-int.
13391 * fns.c (hash_string): New function, taken from sxhash_string.
13392 Do not discard information about ASCII character case; this
13393 discarding is no longer needed.
13394 (sxhash-string): Use it. Change sig to match it. Caller changed.
13395 * lisp.h: Declare it.
13396 * lread.c (hash_string): Remove, since we now use fns.c's version.
13397 The fns.c version returns a wider integer if --with-wide-int is
13398 specified, so this should help the quality of the hashing a bit.
13400 * emacs.c: Integer overflow minor fix.
13401 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
13402 Define only if GNU_LINUX.
13403 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
13405 * dispnew.c: Integer signedness and overflow fixes.
13406 Remove unnecessary forward decls, that were a maintenance hassle.
13407 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
13409 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
13410 (scrolling_window): Use ptrdiff_t, not int, for byte count.
13411 (prepare_desired_row, line_draw_cost):
13412 Use int, not unsigned, where either works.
13413 (save_current_matrix, restore_current_matrix):
13414 Use ptrdiff_t, not size_t, where either works.
13415 (init_display): Check for overflow more accurately, and without
13416 relying on undefined behavior.
13418 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
13419 Remove, replacing with the new symbols in lisp.h. All uses changed.
13420 * fileio.c (make_temp_name):
13421 * filelock.c (lock_file_1, lock_file):
13422 * xdisp.c (message_dolog):
13423 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
13424 Use pMd etc. instead.
13425 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
13426 replacing the pWIDE etc. symbols removed from editfns.c.
13428 * keyboard.h (num_input_events): Now uintmax_t.
13429 This is (very slightly) less likely to mess up due to wraparound.
13432 * buffer.c: Integer signedness fixes.
13433 (alloc_buffer_text, enlarge_buffer_text):
13434 Use ptrdiff_t rather than size_t when either will do, as we prefer
13437 * alloc.c: Integer signedness and overflow fixes.
13438 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
13439 (__malloc_size_t): Default to size_t, not to int.
13440 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
13441 (Fgarbage_collect, mark_object_loop_halt, mark_object):
13442 Prefer ptrdiff_t to size_t when either would do, as we prefer
13444 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
13445 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
13446 Now const. Initialize with values that are in range even if char
13448 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
13449 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
13450 These functions do the right thing with sizes > 2**32.
13451 (check_depth): Now ptrdiff_t, not int.
13452 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
13453 Adjust to new way of storing sizes. Check for size overflow bugs
13455 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
13456 slightly wrong anyway, as it missed one instance of
13457 XMALLOC_OVERRUN_CHECK_OVERHEAD.
13458 (refill_memory_reserve): Omit needless cast to size_t.
13459 (mark_object_loop_halt): Mark as externally visible.
13461 * xselect.c: Integer signedness and overflow fixes.
13462 (Fx_register_dnd_atom, x_handle_dnd_message):
13463 Use ptrdiff_t, not size_t, since we prefer signed.
13464 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
13465 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
13466 x_dnd_atoms_size and x_dnd_atoms_length.
13468 * doprnt.c: Prefer signed to unsigned when either works.
13470 * doprnt.c (doprnt):
13472 * xdisp.c (vmessage):
13473 Use ptrdiff_t, not size_t, when using or implementing doprnt,
13474 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
13475 prefer signed arithmetic to avoid comparison confusion.
13476 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
13477 but is a bit tricky.
13479 Assume freestanding C89 headers, string.h, stdlib.h.
13480 * data.c, doprnt.c, floatfns.c, print.c:
13481 Include float.h unconditionally.
13482 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
13483 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
13484 * regex.c: Likewise for stddef.h, string.h.
13485 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
13486 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
13487 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
13488 (STDC_HEADERS): Remove obsolete defines.
13489 * sysdep.c: Include limits.h unconditionally.
13491 Assume support for memcmp, memcpy, memmove, memset.
13492 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
13493 * regex.c (memcmp, memcpy):
13494 Remove; we assume C89 now.
13496 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
13497 (__malloc_safe_bcopy): Remove; no longer needed.
13499 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
13500 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
13501 well either way, and we prefer signed to unsigned.
13503 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
13505 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
13506 closes the connection while we're reading (bug#9182).
13508 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
13510 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
13511 are specified (Bug#9168).
13513 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
13515 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
13516 Found by GCC static checking and --with-wide-int on a 32-bit host.
13518 2011-07-25 Eli Zaretskii <eliz@gnu.org>
13520 * xdisp.c (compute_display_string_pos): Fix logic of caching
13521 previous display string position. Initialize cached_prev_pos to
13522 -1. Fixes slow-down at the beginning of a buffer.
13524 2011-07-24 Eli Zaretskii <eliz@gnu.org>
13526 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
13527 for attrs[LFACE_FONTSET_INDEX].
13529 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
13531 * xml.c (parse_region): Remove unused local
13532 that was recently introduced.
13534 2011-07-23 Eli Zaretskii <eliz@gnu.org>
13536 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
13537 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
13539 * xdisp.c (move_it_in_display_line_to): Record the best matching
13540 position for TO_CHARPOS while scanning the line, and restore it on
13541 exit if none of the characters scanned was an exact match.
13542 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
13543 when exact match is impossible due to invisible text, and the
13544 lines are truncated.
13546 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
13548 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
13551 2011-07-22 Eli Zaretskii <eliz@gnu.org>
13553 Fix a significant slow-down of cursor motion with C-n, C-p,
13554 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
13555 auto-repeat under bidi redisplay in fontified buffers.
13556 * xdisp.c (compute_stop_pos_backwards): New function.
13557 (next_element_from_buffer): Call compute_stop_pos_backwards to
13558 find a suitable prev_stop when we find ourselves before
13560 (reseat): Don't look for prev_stop, as that could mean a very long
13562 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
13563 <cached_disp_overlay_modiff>: Cache for last found display string
13565 (compute_display_string_pos): Return the cached position if asked
13566 about the same buffer in the same area of character positions, and
13567 the buffer wasn't changed since the time the display string
13568 position was cached.
13570 2011-07-22 Eli Zaretskii <eliz@gnu.org>
13572 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
13573 is an integer, which is important for empty lines. (Bug#9149)
13575 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
13577 * frame.c (Fmodify_frame_parameters): In tty case, update the
13578 default face if necessary (Bug#4238).
13580 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
13582 * editfns.c (Fstring_to_char): No need to explain what a character
13583 is in the docstring (Bug#6576).
13585 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
13587 * xml.c (parse_region): Make sure we always return a tree.
13589 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
13591 * xml.c (parse_region): If a document contains only comments,
13594 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
13596 * xml.c (make_dom): Return comments, too.
13598 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
13601 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
13602 and the surrounding thread.
13603 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
13604 rather than fgets, and retry after EINTR. Otherwise, 'emacs
13605 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
13607 * s/openbsd.h (BROKEN_SIGIO): Define.
13608 * unexelf.c (unexec) [__OpenBSD__]:
13609 Don't update the .mdebug section of the Alpha COFF symbol table.
13611 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
13613 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
13616 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
13618 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
13619 This fixes some race conditions on the permissions of any newly
13622 * alloc.c (valid_pointer_p): Use pipe, not open.
13623 This fixes some permissions issues when debugging.
13625 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
13626 If fchown fails to set both uid and gid, try to set just gid,
13627 as that is sometimes allowed. Adjust the file's mode to eliminate
13628 setuid or setgid bits that are inappropriate if fchown fails.
13630 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
13632 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
13633 to compare Lisp_Objects.
13634 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
13635 global_gnutls_log_level, don't mistake it for a Lisp_Object.
13636 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
13638 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
13640 * lread.c (read_integer): Unread even EOF character.
13641 (read1): Likewise. Properly record start position of symbol.
13643 * lread.c (read1): Read `#:' as empty uninterned symbol if no
13644 symbol character follows.
13646 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
13648 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
13649 This works around a problem with the previous change to Fcopy_file.
13650 Recent glibc declares fchown with __attribute__((warn_unused_result)),
13651 and without this change, GCC might complain about discarding
13652 fchown's return value.
13654 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
13656 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
13658 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
13660 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
13662 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
13664 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
13665 it's used from the C level.
13667 * process.c: Use the same condition for POLL_FOR_INPUT in both
13668 keyboard.c and process.c (bug#1858).
13670 2011-07-09 Lawrence Mitchell <wence@gmx.li>
13672 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
13673 (Fgnutls_boot): Use it.
13675 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
13677 * doc.c (Fsubstitute_command_keys): Revert last change.
13679 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
13681 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
13682 quotes the next character, and doesn't affect other longer
13683 sequences (bug#8935).
13685 * lread.c (syms_of_lread): Clarify that is isn't only
13686 `eval-buffer' and `eval-defun' that's affected by
13687 `lexical-binding' (bug#8460).
13689 2011-07-15 Eli Zaretskii <eliz@gnu.org>
13691 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
13692 bidi redisplay when a line includes both an image and is truncated.
13694 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
13696 Fix minor problems found by static checking.
13697 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
13698 (elsz): Now a signed constant, not a size_t var. We prefer signed
13699 types to unsigned, to avoid integer comparison confusion. Without
13700 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
13701 "cannot optimize loop, the loop counter may overflow", a symptom
13703 * indent.c (Fvertical_motion): Mark locals as initialized.
13704 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
13706 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
13708 * search.c (Fre_search_backward): Mention `case-fold-search' in
13709 all the re_search_* functions (bug#8138).
13711 * keyboard.c (Fopen_dribble_file): Document when the file is

13724 bidi_it->string.schars.
13725 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
13726 NULL (avoids a crash in bidi_paragraph_init).
13727 Initialize itb.string.lstring.
13728 (init_iterator): Call bidi_init_it only of a valid
13729 buffer position was specified. Initialize paragraph_embedding to
13731 (reseat_to_string): Initialize the bidi iterator.
13732 (display_string): If we need to ignore text properties of
13733 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
13734 original value of -1 will not work with bidi.)
13735 (compute_display_string_pos): First arg is now struct
13736 `text_pos *'; all callers changed. Support display properties on
13738 (compute_display_string_end): Support display properties on Lisp
13740 (init_iterator, reseat_1, reseat_to_string): Initialize the
13741 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
13742 when iterating on a string not from display properties).
13743 (compute_display_string_pos, compute_display_string_end):
13744 Fix calculation of the object to scan. Fixes an error when using
13746 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
13747 base_level_stop; instead, set base_level_stop to BEGV.
13748 Fixes crashes in vertical-motion.
13749 (next_element_from_buffer): Improve commentary for when
13750 the iterator is before prev_stop.
13751 (init_iterator): Initialize bidi_p from the default value of
13752 bidi-display-reordering, not from buffer-local value. Use the
13753 buffer-local value only if initializing for buffer iteration.
13754 (handle_invisible_prop): Support invisible properties on strings
13755 that are being bidi-reordered.
13756 (set_iterator_to_next): Support bidi reordering of C strings and
13758 (next_element_from_string): Support bidi reordering of Lisp
13760 (handle_stop_backwards): Support Lisp strings as well.
13761 (display_string): Support display of R2L glyph rows.
13762 Use IT_STRING_CHARPOS when displaying from a Lisp string.
13763 (init_iterator): Don't initialize it->bidi_p for strings
13765 (reseat_to_string): Initialize it->bidi_p for strings here.
13766 (next_element_from_string, next_element_from_c_string)
13767 (next_element_from_buffer): Add xassert's for correspondence
13768 between IT's object being iterated and it->bidi_it.string

13771 (next_element_from_c_string): Handle the case of the first string
13772 character that is not the first one in the visual order.
13773 (get_visually_first_element): New function, refactored from common
13774 parts of next_element_from_buffer, next_element_from_string, and
13775 next_element_from_c_string.
13776 (tool_bar_lines_needed, redisplay_tool_bar)
13777 (display_menu_bar): Force left-to-right direction. Add a FIXME
13778 comment for making that be controlled by a user option.
13779 (push_it, pop_it): Save and restore the state of the
13780 bidi iterator. Save and restore the bidi_p flag.
13781 (pop_it): Iterate out of display property for string iteration as
13783 (iterate_out_of_display_property): Support iteration over strings.
13784 (handle_single_display_spec): Set up it->bidi_it for iteration
13785 over a display string, and call bidi_init_it.
13786 (handle_single_display_spec, next_overlay_string)
13787 (get_overlay_strings_1, push_display_prop): Set up the bidi
13788 iterator for displaying display or overlay strings.
13789 (forward_to_next_line_start): Don't use the shortcut if
13791 (back_to_previous_visible_line_start): If handle_display_prop
13792 pushed the iterator stack, restore the internal state of the bidi
13793 iterator by calling bidi_pop_it same number of times.
13794 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
13795 and we are bidi-iterating, don't decrement the iterator position;
13796 instead, set the first_elt flag in the bidi iterator, to produce
13798 (reseat_1): Remove redundant setting of string_from_display_prop_p.
13799 (push_display_prop): xassert that we are iterating a buffer.
13800 (push_it, pop_it): Save and restore paragraph_embedding member.
13801 (handle_single_display_spec, next_overlay_string)
13802 (get_overlay_strings_1, reseat_1, reseat_to_string)
13803 (push_display_prop): Set up the `unibyte' member of bidi_it.string
13804 correctly. Don't assume unibyte strings are not bidi-reordered.
13805 (compute_display_string_pos)
13806 (compute_display_string_end): Fix handling the case of C string.
13807 (push_it, pop_it): Save and restore from_disp_prop_p.

13812 popping after iteration over a string that came from a display
13813 property. Fix a typo in popping stretch info. Add an assertion
13814 for verifying that the iterator position is in sync with the bidi
13816 (handle_single_display_spec, get_overlay_strings_1)
13817 (push_display_prop): Fix initialization of paragraph direction for
13818 string when that of the parent object is not yet determined.
13819 (reseat_1): Call bidi_init_it to resync the bidi
13820 iterator with IT's position. (Bug#7616)
13821 (find_row_edges): If ROW->start.pos gives position
13822 smaller than min_pos, use it as ROW->minpos. (Bug#7616)
13823 (handle_stop, back_to_previous_visible_line_start, reseat_1):
13824 Reset the from_disp_prop_p flag.
13825 (SAVE_IT, RESTORE_IT): New macros.

13827 (back_to_previous_visible_line_start)
13828 (move_it_in_display_line_to, move_it_in_display_line)
13829 (move_it_to, move_it_vertically_backward, move_it_by_lines)
13830 (try_scrolling, redisplay_window, display_line): Use them when
13831 saving a temporary copy of the iterator and restoring it back.
13832 (back_to_previous_visible_line_start, reseat_1)
13833 (init_iterator): Empty the bidi cache "stack".
13834 (move_it_in_display_line_to): If iterator ended up at
13835 EOL, but we never saw any buffer positions smaller than
13836 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
13837 motion in bidi-reordered lines.
13838 (move_it_in_display_line_to): Record prev_method and prev_pos
13839 immediately before the call to set_iterator_to_next. Fixes cursor
13840 motion in bidi-reordered lines with stretch glyphs and strings
13841 displayed in margins. (Bug#8133) (Bug#8867)
13842 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
13844 (pos_visible_p): Support positions in bidi-reordered lines.
13845 Save and restore bidi cache.
13847 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.
13848 (bidi_paragraph_info): Delete unused struct.
13849 (bidi_cache_idx, bidi_cache_last_idx): Declare EMACS_INT.
13850 (bidi_cache_start): New variable.
13851 (bidi_cache_reset): Reset bidi_cache_idx to bidi_cache_start, not
13853 (bidi_cache_fetch_state, bidi_cache_search)
13854 (bidi_cache_find_level_change, bidi_cache_iterator_state)

13859 (bidi_fetch_char): Accept new argument STRING; all callers
13860 changed. Support iteration over a string. Support strings with
13861 display properties. Support unibyte strings. Fix the type of
13862 `len' according to what STRING_CHAR_AND_LENGTH expects.
13863 (bidi_paragraph_init, bidi_resolve_explicit_1)
13864 (bidi_resolve_explicit, bidi_resolve_weak)
13865 (bidi_level_of_next_char, bidi_move_to_visually_next):
13866 Support iteration over a string.
13867 (bidi_set_sor_type, bidi_resolve_explicit_1)
13868 (bidi_resolve_explicit, bidi_type_of_next_char): ignore_bn_limit
13869 can now be zero (for strings); special values 0 and -1 were
13870 changed to -1 and -2, respectively.
13871 (bidi_char_at_pos): New function.
13872 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak):
13873 Call it instead of FETCH_MULTIBYTE_CHAR.

13883 (bidi_initialize): Initialize the bidi cache start stack pointer.
13884 (bidi_cache_ensure_space): New function, refactored from part of

13958 2011-07-13 Paul Eggert <eggert@cs.ucla.edu>
13960 * buffer.c (Fget_buffer_create): Initialize inhibit_shrinking.
13961 The old code sometimes used this field without initializing it.
13963 * alloc.c (gc_sweep): Don't read past end of array.
13964 In theory, the old code could also have corrupted Emacs internals,
13965 though it'd be very unlikely.

14228 (clone_per_buffer_values): Don't assume that
14229 sizeof (struct buffer) is a multiple of sizeof (Lisp_Object).
14230 This isn't true in general, and it's particularly not true
14231 if Emacs is configured with --with-wide-int.
14232 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
14233 New macros, used in the buffer.c change.

14269 Random fixes. E.g., (random) never returned negative values.
14270 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
14271 subseconds part to the entropy, as that's a bit more random.
14272 Prefer signed to unsigned, since the signedness doesn't matter and
14273 in general we prefer signed. When given a limit, use a
14274 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
14275 latter isn't right if USE_2_TAGS_FOR_INTS.
14276 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
14277 not 0..VALMASK. Don't discard "excess" bits that random () returns.

14287 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
14289 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
14290 This is more efficient than Ffile_directory_p and avoids a minor race.
14292 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
14294 * buffer.c (Foverlay_put): Say what the return value is
14297 * fileio.c (barf_or_query_if_file_exists): Check first if the file
14298 is a directory before asking whether to use the file name
14300 (barf_or_query_if_file_exists): Make the "File is a directory"
14301 error be more correct.
14303 * fns.c (Frequire): Remove the mention of the .gz files, since
14304 that's installation-specific, but keep the mention of
14305 `get-load-suffixes'.

14309 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

14317 Qgnutls_bootprop_verify_error (which is no longer used).
14319 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
14320 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
14321 Also (re)move comments that are misplaced or no longer relevant.
14323 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
14325 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

14422 * eval.c (struct backtrace): Simplify and port the data structure.
14423 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
14424 signed bit field, as this assumption is not portable and it makes
14425 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
14426 "char debug_on_exit : 1" as this is not portable either; instead,
14427 use the portable "unsigned int debug_on_exit : 1". Remove unused
14428 member evalargs. Remove obsolete comments about cc bombing out.
14430 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

14502 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
14503 and use min_width/height from frames size_hint to set
14504 min_width/height (Bug#8919).

14597 (PRINTPREPARE, printchar, strout):
14598 Don't set size unless allocation succeeds.
14600 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
14601 for sizes. Check for string overflow more accurately.

14612 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
14614 * lread.c: Integer overflow fixes.
14615 (read_integer): Radix is now EMACS_INT, not int,
14616 to improve quality of diagnostics for out-of-range radices.
14617 Calculate buffer size correctly for out-of-range radices.
14618 (read1): Check for integer overflow in radices, and in
14619 read-circle numbers.
14620 (read_escape): Avoid int overflow.
14621 (Fload, openp, read_buffer_size, read1)
14622 (substitute_object_recurse, read_vector, read_list, map_obarray):

14645 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
14646 The following patches are for when GLYPH_DEBUG && !XASSERT.

14663 on undefined behavior with wrong number of arguments.
14664 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
14665 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
14666 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
14667 since we're not interested in debugging glyphs with old libraries.
14668 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
14669 GCC 4.6.0's static checking.
14671 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>

14710 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
14711 (x_session_initialize): Do not assume string length fits in int.
14713 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
14714 This is unlikely, but can occur if DPI is outlandish.
14716 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):

14732 (message_dolog): Don't assume print length fits in 39 bytes.
14733 (display_mode_element): Don't assume strlen fits in int.
14735 * termcap.c: Don't assume sizes fit in int and never overflow.

14739 * minibuf.c (Fread_buffer):
14740 * lread.c (intern, intern_c_string):
14741 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:

14759 Don't assume pid_t and time_t fit in unsigned long.
14760 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
14761 (current_lock_owner): Prefer signed type for sizes.
14762 Use memcpy, not strncpy, where memcpy is what is really wanted.
14763 Don't assume (via atoi) that time_t and pid_t fit in int.
14764 Check for time_t and/or pid_t out of range, e.g., via a network share.
14765 Don't alloca where an auto var works fine.

14770 (directory_file_name): Don't assume string length fits in long.
14771 (make_temp_name): Don't assume pid fits in int, or that its print
14772 length is less than 20.
14774 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
14776 * coding.c (make_subsidiaries): Don't assume string length fits in int.
14778 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
14780 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
14781 We prefer signed integers, even for size calculations.
14783 * emacs.c: Don't assume string length fits in 'int'.
14784 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
14785 (main): Don't invoke strlen when not needed.
14787 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
14788 (XD_DEBUG_MESSAGE): Don't waste a byte.
14790 * callproc.c (getenv_internal_1, getenv_internal)
14791 (Fgetenv_internal):
14792 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
14794 * lread.c (invalid_syntax): Omit length argument.
14795 All uses changed. This doesn't fix a bug, but it simplifies the
14796 code away from its former Hollerith-constant appearance, and it's
14797 one less 'int' to worry about when looking at integer-overflow issues.
14798 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
14800 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
14801 This didn't break anything, but it didn't help either.
14802 It's confusing to put a bogus integer in a place where the actual
14803 value does not matter.
14804 (LIST_END_P): Remove unused macro and its bogus comment.
14805 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
14807 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
14808 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
14810 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
14811 We prefer signed types, and the value cannot exceed the EMACS_INT
14812 range anyway (because otherwise the length would not be representable).
14813 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
14814 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
14815 This avoids a GCC warning when WIDE_EMACS_INT.
14817 * indent.c (sane_tab_width): New function.
14818 (current_column, scan_for_column, Findent_to, position_indentation)
14819 (compute_motion): Use it. This is just for clarity.
14820 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
14822 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
14824 * lisp.h (lint_assume): New macro.
14825 * composite.c (composition_gstring_put_cache):
14826 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
14828 * editfns.c, insdel.c:
14829 Omit unnecessary forward decls, to simplify future changes.
14831 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
14833 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
14835 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
14836 Use much-faster test for byte-length change.
14837 Don't assume string byte-length fits in 'int'.
14838 Check that character arg fits in 'int'.
14839 (mapcar1): Declare byte as byte, for clarity.
14841 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
14843 * fns.c (concat): Catch string overflow earlier.
14844 Do not rely on integer wraparound.
14846 * dispextern.h (struct it.overlay_strings_charpos)
14847 (struct it.selective): Now EMACS_INT, not int.
14848 * xdisp.c (forward_to_next_line_start)
14849 (back_to_previous_visible_line_start)
14850 (reseat_at_next_visible_line_start, next_element_from_buffer):
14851 Don't arbitrarily truncate the value of 'selective' to int.
14853 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
14855 * composite.c: Don't truncate sizes to 'int'.
14856 (composition_gstring_p, composition_reseat_it)
14857 (composition_adjust_point): Use EMACS_INT, not int.
14858 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
14859 not EMACS_UINT, for indexes.
14861 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
14863 * buffer.c: Include <verify.h>.
14864 (struct sortvec.priority, struct sortstr.priority):
14865 Now EMACS_INT, not int.
14866 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
14867 (struct sortstr.size, record_overlay_string)
14868 (struct sortstrlist.size, struct sortlist.used):
14869 Don't truncate size to int.
14870 (record_overlay_string): Check for size-calculation overflow.
14871 (init_buffer_once): Check at compile-time, not run-time.
14873 2011-06-22 Jim Meyering <meyering@redhat.com>
14875 Don't leak an XBM-image-sized buffer
14876 * image.c (xbm_load): Free the image buffer after using it.
14878 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
14881 * composite.c (find_automatic_composition): Omit needless 'return 0;'
14882 that Sun C diagnosed.
14883 * fns.c (secure_hash): Fix pointer signedness issue.
14884 * intervals.c (static_offset_intervals): New function.
14885 (offset_intervals): Use it.
14887 2011-06-21 Leo Liu <sdl.web@gmail.com>
14890 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
14893 * fns.c (secure_hash): Rename from crypto_hash_function and change
14894 the first arg to accept symbols.
14895 (Fsecure_hash): New primitive.
14896 (syms_of_fns): New symbols.
14898 2011-06-20 Deniz Dogan <deniz@dogan.se>
14900 * process.c (Fset_process_buffer): Clarify return value in
14903 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
14905 * dispnew.c (add_window_display_history): Use BVAR.
14907 * xdisp.c (debug_method_add): Use BVAR.
14908 (check_window_end, dump_glyph_matrix, dump_glyph)
14909 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
14911 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
14914 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
14915 check till after the cache is created in init_frame_faces.
14917 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
14919 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
14921 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
14923 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
14924 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
14925 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
14927 Improve buffer-overflow checking (Bug#8873).
14928 * fileio.c (Finsert_file_contents):
14929 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
14930 Remove the old (too-loose) buffer overflow checks.
14931 They weren't needed, since make_gap checks for buffer overflow.
14932 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
14933 The old code merely checked for Emacs fixnum overflow, and relied
14934 on undefined (wraparound) behavior. The new code avoids undefined
14935 behavior, and also checks for ptrdiff_t and/or size_t overflow.
14937 * editfns.c (Finsert_char): Don't dump core with very negative counts.
14938 Tune. Don't use wider integers than needed. Don't use alloca.
14939 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
14941 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
14943 * insdel.c, lisp.h (buffer_overflow): New function.
14944 (insert_from_buffer_1, replace_range, replace_range_2):
14945 * insdel.c (make_gap_larger):
14946 * editfns.c (Finsert_char):
14947 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
14949 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
14951 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
14953 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
14955 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
14956 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
14958 * fileio.c: Don't assume EMACS_INT fits in off_t.
14959 (emacs_lseek): New static function.
14960 (Finsert_file_contents, Fwrite_region): Use it.
14961 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
14963 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
14965 * fns.c: Don't overflow int when computing a list length.
14966 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
14967 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
14968 truncation on 64-bit hosts. Check for QUIT every
14969 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
14970 faster and is responsive enough.
14971 (Flength): Report an error instead of overflowing an integer.
14972 (Fsafe_length): Return a float if the value is not representable
14973 as a fixnum. This shouldn't happen except in contrived situations.
14974 (Fnthcdr, Fsort): Don't assume list length fits in int.
14975 (Fcopy_sequence): Don't assume vector length fits in int.
14977 * alloc.c: Check that resized vectors' lengths fit in fixnums.
14978 (header_size, word_size): New constants.
14979 (allocate_vectorlike): Don't check size overflow here.
14980 (allocate_vector): Check it here instead, since this is the only
14981 caller of allocate_vectorlike that could cause overflow.
14982 Check that the new vector's length is representable as a fixnum.
14984 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
14985 The previous code was bogus. For example, next_almost_prime (32)
14986 returned 39, which is undesirable as it is a multiple of 3; and
14987 next_almost_prime (24) returned 25, which is a multiple of 5 so
14988 why was the code bothering to check for multiples of 7?
14990 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
14992 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
14994 Variadic C functions now count arguments with ptrdiff_t.
14995 This partly undoes my 2011-03-30 change, which replaced int with size_t.
14996 Back then I didn't know that the Emacs coding style prefers signed int.
14997 Also, in the meantime I found a few more instances where arguments
14998 were being counted with int, which may truncate counts on 64-bit
14999 machines, or EMACS_INT, which may be unnecessarily wide.
15000 * lisp.h (struct Lisp_Subr.function.aMANY)
15001 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
15002 Arg counts are now ptrdiff_t, not size_t.
15003 All variadic functions and their callers changed accordingly.
15004 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
15005 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
15006 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
15007 * callint.c (Fcall_interactively): Check arg count for overflow,
15008 to avoid potential buffer overrun. Use signed char, not 'int',
15009 for 'varies' array, so that we needn't bother to check its size
15010 calculation for overflow.
15011 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
15012 * eval.c (apply_lambda):
15013 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
15014 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
15015 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
15017 * callint.c (Fcall_interactively): Don't use index var as event count.
15019 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
15020 * mem-limits.h (SIZE): Remove; no longer used.
15022 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
15024 Remove unnecessary casts.
15025 * xterm.c (x_term_init):
15026 * xfns.c (x_set_border_pixel):
15027 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
15028 These aren't needed now that we assume ANSI C.
15030 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
15031 It's more likely to cause problems (due to unsigned overflow)
15034 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
15036 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
15038 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
15040 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
15042 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
15044 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
15046 GLYPH_CODE_FACE returns EMACS_INT, not int.
15047 * dispextern.h (merge_faces):
15048 * xfaces.c (merge_faces):
15049 * xdisp.c (get_next_display_element, next_element_from_display_vector):
15050 Don't assume EMACS_INT fits in int.
15052 * character.h (CHAR_VALID_P): Remove unused parameter.
15053 * fontset.c, lisp.h, xdisp.c: All uses changed.
15055 * editfns.c (Ftranslate_region_internal): Omit redundant test.
15057 * fns.c (concat): Minor tuning based on overflow analysis.
15058 This doesn't fix any bugs. Use int to hold character, instead
15059 of constantly refetching from Emacs object. Use XFASTINT, not
15060 XINT, for value known to be a character. Don't bother comparing
15061 a single byte to 0400, as it's always less.
15063 * floatfns.c (Fexpt):
15064 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
15066 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
15069 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
15071 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
15072 Without this fix, on a 64-bit host (aset S 0 4294967386) would
15073 incorrectly succeed when S was a string, because 4294967386 was
15074 truncated before it was used.
15076 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
15077 Otherwise, an out-of-range integer could cause undefined behavior
15080 * composite.c: Use int, not EMACS_INT, for characters.
15081 (fill_gstring_body, composition_compute_stop_pos): Use int, not
15082 EMACS_INT, for values that are known to be in character range.
15083 This doesn't fix any bugs but is the usual style inside Emacs and
15084 may generate better code on 32-bit machines.
15086 Make sure a 64-bit char is never passed to ENCODE_CHAR.
15087 This is for reasons similar to the recent CHAR_STRING fix.
15088 * charset.c (Fencode_char): Check that character arg is actually
15089 a character. Pass an int to ENCODE_CHAR.
15090 * charset.h (ENCODE_CHAR): Verify that the character argument is no
15091 wider than 'int', as a compile-time check to prevent future regressions
15094 * character.c (char_string): Remove unnecessary casts.
15096 Make sure a 64-bit char is never passed to CHAR_STRING.
15097 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
15098 by silently ignoring the top 32 bits, allowing some values
15099 that were far too large to be valid characters.
15100 * character.h: Include <verify.h>.
15101 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
15102 arguments are no wider than unsigned, as a compile-time check
15103 to prevent future regressions in this area.
15105 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
15106 (Fsubst_char_in_region):
15108 * xdisp.c (decode_mode_spec_coding):
15109 Adjust to CHAR_STRING's new requirement.
15110 * editfns.c (Finsert_char, Fsubst_char_in_region):
15111 * fns.c (concat): Check that character args are actually
15112 characters. Without this test, these functions did the wrong
15113 thing with wildly out-of-range values on 64-bit hosts.
15115 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
15116 These casts should not be needed on 32-bit hosts, either.
15117 * keyboard.c (read_char):
15118 * lread.c (Fload): Remove casts to unsigned.
15120 * lisp.h (UNSIGNED_CMP): New macro.
15121 This fixes comparison bugs on 64-bit hosts.
15122 (ASCII_CHAR_P): Use it.
15123 * casefiddle.c (casify_object):
15124 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
15125 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
15126 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
15127 * dispextern.h (FACE_FROM_ID):
15128 * keyboard.c (read_char): Use UNSIGNED_CMP.
15130 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
15131 not to EMACS_INT, to avoid GCC warning.
15133 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
15135 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
15136 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
15137 isn't needed on 32-bit machines.
15139 * buffer.c (Fgenerate_new_buffer_name):
15140 Use EMACS_INT for count, not int.
15141 (advance_to_char_boundary): Return EMACS_INT, not int.
15143 * data.c (Qcompiled_function): Now static.
15145 * window.c (window_body_lines): Now static.
15147 * image.c (gif_load): Rename local to avoid shadowing.
15149 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
15150 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
15151 * alloc.c (make_save_value): Integer argument is now of type
15152 ptrdiff_t, not int.
15153 (mark_object): Use ptrdiff_t, not int.
15154 * lisp.h (pD): New macro.
15155 * print.c (print_object): Use it.
15157 * alloc.c: Use EMACS_INT, not int, to count objects.
15158 (total_conses, total_markers, total_symbols, total_vector_size)
15159 (total_free_conses, total_free_markers, total_free_symbols)
15160 (total_free_floats, total_floats, total_free_intervals)
15161 (total_intervals, total_strings, total_free_strings):
15162 Now EMACS_INT, not int. All uses changed.
15163 (Fgarbage_collect): Compute overall total using a double, so that
15164 integer overflow is less likely to be a problem. Check for overflow
15165 when converting back to an integer.
15166 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
15167 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
15168 These were 'int' variables that could overflow on 64-bit hosts;
15169 they were never used, so remove them instead of repairing them.
15170 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
15171 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
15172 Previously, this ceilinged at INT_MAX, but that doesn't work on
15174 (allocate_pseudovector): Don't use EMACS_INT when int would do.
15176 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
15177 (allocate_vectorlike): Check for ptrdiff_t overflow.
15178 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
15179 when a (possibly-narrower) signed value would do just as well.
15180 We prefer using signed arithmetic, to avoid comparison confusion.
15182 * alloc.c: Catch some string size overflows that we were missing.
15183 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
15184 for convenience in STRING_BYTES_MAX.
15185 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
15186 The definition here is exact; the one in lisp.h was approximate.
15187 (allocate_string_data): Check for string overflow. This catches
15188 some instances we weren't catching before. Also, it catches
15189 size_t overflow on (unusual) hosts where SIZE_MAX <= min
15190 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
15191 and ptrdiff_t and EMACS_INT are both 64 bits.
15193 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
15194 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
15195 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
15197 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
15199 * alloc.c (Fmake_string): Check for out-of-range init.
15201 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
15203 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
15205 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
15207 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
15208 xg_get_default_scrollbar_width.
15210 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
15211 (int_gtk_range_get_value): Move to the scroll bar part of the file.
15212 (style_changed_cb): Call update_theme_scrollbar_width and call

15694 (Fselected_window, select_window, Fselect_window): Move up in
15695 code. Minor doc-string fixes.
15697 2011-06-06 Paul Eggert <eggert@cs.ucla.edu>
15699 * alloc.c (memory_full) [SYSTEM_MALLOC]: Port to MacOS (Bug#8800).
15700 Do not assume that spare memory exists; that assumption is valid
15701 only if SYSTEM_MALLOC.
15702 (LARGE_REQUEST): New macro, so that the issue of large requests
15703 is separated from the issue of spare memory.
15705 2011-06-05 Andreas Schwab <schwab@linux-m68k.org>
15707 * editfns.c (Fformat): Correctly handle zero flag with hexadecimal

15733 New error handlers.
15734 (x_clipboard_manager_save_frame, x_clipboard_manager_save_all):
15735 Obey Vx_select_enable_clipboard_manager. Catch errors in

15755 Support bidi reordering of text covered by display properties.
15757 * bidi.c (bidi_copy_it): Use offsetof instead of emulating it.
15758 (bidi_fetch_char, bidi_fetch_char_advance): New functions.
15759 (bidi_cache_search, bidi_cache_iterator_state)
15760 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
15761 (bidi_level_of_next_char, bidi_move_to_visually_next):
15762 Support character positions inside a run of characters covered by a
15764 (bidi_paragraph_init, bidi_resolve_explicit_1)
15765 (bidi_level_of_next_char): Call bidi_fetch_char and
15766 bidi_fetch_char_advance instead of FETCH_CHAR and
15767 FETCH_CHAR_ADVANCE.

15769 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
15771 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
15772 instead of using explicit *_CHAR codes.
15773 (bidi_resolve_explicit, bidi_resolve_weak):
15774 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
15775 bidirectional text is supported only in multibyte buffers.
15776 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
15777 it to initialize the frame_window_p member of struct bidi_it.

15781 bidi_it->nchars is non-positive.
15782 (bidi_level_of_next_char): Don't try to lookup the cache for the
15783 next/previous character if nothing is cached there yet, or if we
15784 were just reseat()'ed to a new position.
15786 * xdisp.c (set_cursor_from_row): Set start and stop points
15787 according to the row's direction when priming the loop that looks
15788 for the glyph on which to display cursor.
15789 (single_display_spec_intangible_p): Function deleted.
15790 (display_prop_intangible_p): Reimplement to call
15791 handle_display_spec instead of single_display_spec_intangible_p.
15792 Accept 3 additional arguments needed by handle_display_spec.
15793 This fixes incorrect cursor motion across display property with complex
15794 values: lists, `(when COND...)' forms, etc.
15795 (single_display_spec_string_p): Support property values that are
15796 lists with the argument STRING its top-level element.
15797 (display_prop_string_p): Fix the condition for processing a
15798 property that is a list to be consistent with handle_display_spec.
15799 (handle_display_spec): New function, refactored from the
15800 last portion of handle_display_prop.
15801 (compute_display_string_pos): Accept additional argument
15802 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
15803 value of a `display' property is a "replacing spec".
15804 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
15805 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
15806 the display property, but just return a value indicating whether
15807 the display property will replace the characters it covers.
15808 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
15809 frame_window_p members of struct bidi_it.
15810 (compute_display_string_pos, compute_display_string_end):
15812 (push_it): Accept second argument POSITION, where pop_it should
15813 jump to continue iteration.
15814 (reseat_1): Initialize bidi_it.disp_pos.
15816 * keyboard.c (adjust_point_for_property): Adjust the call to
15817 display_prop_intangible_p to its new signature.
15819 * dispextern.h (struct bidi_it): New member frame_window_p.
15820 (bidi_init_it): Update prototypes.
15821 (display_prop_intangible_p): Update prototype.
15822 (compute_display_string_pos, compute_display_string_end):

15827 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
15829 Malloc failure behavior now depends on size of allocation.
15830 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
15831 * lisp.h: Change signatures accordingly.
15832 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
15833 All callers changed. (Bug#8762)
15835 * gnutls.c: Use Emacs's memory allocators.
15836 Without this change, the gnutls library would invoke malloc etc.
15837 directly, which causes problems on non-SYNC_INPUT hosts, and which
15838 runs afoul of improving memory_full behavior. (Bug#8761)
15839 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
15840 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
15841 xfree instead of the default malloc, realloc, free.
15842 (Fgnutls_boot): No need to check for memory allocation failure,
15843 since xmalloc does that for us.
15845 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
15846 * category.c (hash_get_category_set):
15847 * ccl.c (ccl_driver):
15848 * charset.c (Fdefine_charset_internal):

15859 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
15860 (Fsxhash, Fgethash, Fputhash, Fmaphash):
15861 * image.c (make_image, search_image_cache, lookup_image)
15862 (xpm_put_color_table_h):
15863 * lisp.h (struct Lisp_Hash_Table):
15864 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
15865 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
15866 for hashes and hash indexes, instead of 'unsigned' and 'int'.
15867 * alloc.c (allocate_vectorlike):
15868 Check for overflow in vector size calculations.
15869 * ccl.c (ccl_driver):
15870 Check for overflow when converting EMACS_INT to int.
15871 * fns.c, image.c: Remove unnecessary static decls that would otherwise
15872 need to be updated by these changes.
15873 * fns.c (make_hash_table, maybe_resize_hash_table):
15874 Check for integer overflow with large hash tables.
15875 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
15876 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
15877 (SXHASH_REDUCE): New macro.
15878 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
15879 Use it instead of discarding useful hash info with large hash values.
15880 (sxhash_float): New function.
15881 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
15882 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
15883 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
15884 Rewrite to use FIXNUM_BITS, as this simplifies things.
15885 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
15886 Adjust signatures to match updated version of code.
15887 (consing_since_gc): Now EMACS_INT, since a single hash table can
15888 use more than INT_MAX bytes.
15890 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
15892 Make it possible to build with GCC-4.6+ -O2 -flto.
15894 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
15896 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
15898 * minibuf.c (get_minibuffer, read_minibuf_unwind):
15899 Call minibuffer-inactive-mode.
15901 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
15903 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
15904 Update dependencies.
15906 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
15908 * data.c (init_data): Remove code for UTS, this system is not
15911 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
15913 Don't force ./temacs to start in terminal mode.
15915 * frame.c (make_initial_frame): Initialize faces in all cases, not
15916 only when CANNOT_DUMP is defined.
15917 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
15919 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
15921 * dispnew.c (add_window_display_history): Use const for the string
15922 pointer. Remove declaration, not needed.
15924 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
15926 Use 'inline', not 'INLINE'.
15927 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
15928 * alloc.c, fontset.c (INLINE): Remove.
15929 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
15930 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
15931 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
15932 * gmalloc.c (register_heapinfo): Use inline unconditionally.
15933 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
15935 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
15937 Make it possible to run ./temacs.
15939 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
15940 syms_of_callproc does the same thing. Remove test for
15941 "initialized", do it in the caller.
15942 * emacs.c (main): Avoid calling set_initial_environment when dumping.
15944 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
15946 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
15947 (read_minibuf): Use get_minibuffer.
15948 (syms_of_minibuf): Use DEFSYM.
15949 (Qmetadata): New var.
15950 * data.c (Qbuffer): Don't make it static.
15951 (syms_of_data): Use DEFSYM.
15953 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
15955 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
15956 (CCL_CODE_MIN): New macro.
15958 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
15960 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
15962 * eval.c (Qdebug): Now static.
15963 * lisp.h (Qdebug): Remove decl. This reverts a part of the
15964 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
15965 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
15967 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
15969 * image.c: Various fixes to ImageMagick code comments.
15970 (Fimagemagick_types): Doc fix.
15972 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
15974 Minor fixes prompted by GCC 4.6.0 warnings.
15976 * xselect.c (converted_selections, conversion_fail_tag): Now static.
15978 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
15979 (x_clipboard_manager_save_all): Move extern decl to ...
15980 * xterm.h: ... here, so that it can be checked for consistency.
15982 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
15984 * xselect.c (x_clipboard_manager_save_frame)
15985 (x_clipboard_manager_save_all): New functions.
15986 (Fx_clipboard_manager_save): Lisp function deleted.
15988 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
15989 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
15991 * xterm.h: Update prototype.
15993 2011-05-28 William Xu <william.xwl@gmail.com>
15995 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
15996 exiting (Bug#8239).
15998 2011-05-28 Jim Meyering <meyering@redhat.com>
16000 Avoid a sign-extension bug in crypto_hash_function.
16001 * fns.c (to_uchar): Define.
16002 (crypto_hash_function): Use it to convert some newly-signed
16003 variables to unsigned, to avoid sign-extension bugs. For example,
16004 without this change, (md5 "truc") would evaluate to
16005 45723a2aff78ff4fff7fff1114760e62 rather than the expected
16006 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
16007 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
16009 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
16011 Integer overflow fixes.
16013 * dbusbind.c: Serial number integer overflow fixes.
16014 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
16015 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
16016 to hold a serial number that is too large for a fixnum.
16017 (Fdbus_method_return_internal, Fdbus_method_error_internal):
16018 Check for serial numbers out of range. Decode any serial number
16019 that was so large that it became a float. (Bug#8722)
16021 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
16022 (Fdbus_call_method, Fdbus_call_method_asynchronously):
16023 Use XFASTINT rather than XUINT when numbers are nonnegative.
16024 (xd_append_arg, Fdbus_method_return_internal):
16025 (Fdbus_method_error_internal): Likewise. Also, for unsigned
16026 arguments, check that Lisp number is nonnegative, rather than
16027 silently wrapping negative numbers around. (Bug#8722)
16028 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
16031 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
16033 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
16035 ccl: Add integer overflow checks.
16036 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
16037 (IN_INT_RANGE): New macros.
16038 (ccl_driver): Use them to check for integer overflow when
16039 decoding a CCL program. Many of the new checks are whether XINT (x)
16040 fits in int; it doesn't always, on 64-bit hosts. The new version
16041 doesn't catch all possible integer overflows, but it's an
16042 improvement. (Bug#8719)
16044 * alloc.c (make_event_array): Use XINT, not XUINT.
16045 There's no need for unsigned here.
16047 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
16048 This follows up to the 2011-05-06 change that substituted uintptr_t
16049 for EMACS_INT. This case wasn't caught back then.
16051 Rework Fformat to avoid integer overflow issues.
16052 * editfns.c: Include <float.h> unconditionally, as it's everywhere
16053 now (part of C89). Include <verify.h>.
16054 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
16055 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
16056 (Fformat): Avoid the prepass trying to compute sizes; it was only
16057 approximate and thus did not catch overflow reliably. Instead, walk
16058 through the format just once, formatting and computing sizes as we go,
16059 checking for integer overflow at every step, and allocating a larger
16060 buffer as needed. Keep track separately whether the format is
16061 multibyte. Keep only the most-recently calculated precision, rather
16062 than them all. Record whether each argument has been converted to
16063 string. Use EMACS_INT, not int, for byte and char and arg counts.
16064 Support field widths and precisions larger than INT_MAX. Avoid
16065 sprintf's undefined behavior with conversion specifications such as %#d
16066 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
16067 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
16068 formatting out-of-range floating point numbers with int
16069 formats. (Bug#8668)
16071 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
16073 * data.c: Avoid integer truncation in expressions involving floats.
16074 * data.c: Include <intprops.h>.
16075 (arith_driver): When there's an integer overflow in an expression
16076 involving floating point, convert the integers to floating point
16077 so that the resulting value does not suffer from catastrophic
16078 integer truncation. For example, on a 64-bit host (* 4
16079 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
16080 Do not rely on undefined behavior after integer overflow.
16082 merge count_size_as_multibyte, parse_str_to_multibyte
16083 * character.c, character.h (count_size_as_multibyte):
16084 Rename from parse_str_to_multibyte; all uses changed.
16085 Check for integer overflow.
16086 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
16087 since it's now a duplicate of the other. This is more of
16088 a character than a buffer op, so better that it's in character.c.
16089 * fns.c, print.c: Adjust to above changes.
16091 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
16093 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
16095 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
16097 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
16098 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
16099 (x_clipboard_manager_save): Now static.
16100 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
16102 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
16103 (crypto_hash_function): Now static.
16104 Fix pointer signedness problems. Avoid unnecessary initializations.
16106 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
16108 * termhooks.h (Vselection_alist): Make it terminal-local.
16110 * terminal.c (create_terminal): Initialize it.
16112 * xselect.c: Support for clipboard managers.
16113 (Vselection_alist): Move to termhooks.h as terminal-local var.
16114 (LOCAL_SELECTION): New macro.
16115 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
16116 (symbol_to_x_atom): Remove gratuitous arg.
16117 (x_handle_selection_request, lisp_data_to_selection_data)
16118 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
16119 (x_own_selection, x_get_local_selection, x_convert_selection):
16120 New arg, specifying work frame. Use terminal-local Vselection_alist.
16121 (some_frame_on_display): Delete unused function.
16122 (Fx_own_selection_internal, Fx_get_selection_internal)
16123 (Fx_disown_selection_internal, Fx_selection_owner_p)
16124 (Fx_selection_exists_p): New optional frame arg.
16125 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
16126 (x_handle_selection_clear): Don't treat other terminals with the
16127 same keyboard specially. Use the terminal-local Vselection_alist.
16128 (x_clear_frame_selections): Use Frun_hook_with_args.
16130 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
16132 * xterm.h: Add support for those atoms.
16134 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
16136 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
16137 (converted_selections, conversion_fail_tag): New global variables.
16138 (x_selection_request_lisp_error): Free the above.
16139 (x_get_local_selection): Remove unnecessary code.
16140 (x_reply_selection_request): Args changed; handle arbitrary array
16141 of converted selections stored in converted_selections.
16142 Separate the XChangeProperty and SelectionNotify steps.
16143 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
16144 (x_convert_selection): New function.
16145 (x_handle_selection_event): Simplify.
16146 (x_get_foreign_selection): Don't ignore incoming requests while
16147 waiting for an answer; this will fail when we implement
16148 SAVE_TARGETS, and seems unnecessary anyway.
16149 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
16150 (Vx_sent_selection_functions): Doc fix.
16152 2011-05-26 Leo Liu <sdl.web@gmail.com>
16154 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
16156 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16158 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
16160 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
16161 for fringe update if it has periodic bitmap.
16162 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
16163 and fringe_bitmap_periodic_p.
16165 * fringe.c (get_fringe_bitmap_data): New function.
16166 (draw_fringe_bitmap_1, update_window_fringes): Use it.
16167 (update_window_fringes): Record periodicity of fringe bitmap in glyph
16168 row. Mark glyph row for fringe update if periodicity changed.
16170 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
16171 for fringe update unless it has periodic bitmap.
16173 2011-05-25 Kenichi Handa <handa@m17n.org>
16175 * xdisp.c (get_next_display_element): Set correct it->face_id for
16176 a static composition.
16178 2011-05-24 Leo Liu <sdl.web@gmail.com>
16181 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
16183 * fns.c (crypto_hash_function, Fsha1): New function.
16184 (Fmd5): Use crypto_hash_function.
16185 (syms_of_fns): Add Ssha1.
16187 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
16189 * gnutls.c: Remove unused macros.
16190 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
16191 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
16192 Remove macros that are defined and never used.
16193 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
16195 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
16197 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
16198 (Fx_get_selection_internal): Minor cleanup.
16199 (Fx_own_selection_internal): Rename arguments for consistency with
16202 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
16204 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
16206 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
16208 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
16210 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16212 * dispnew.c (scrolling_window): Don't exclude the case that the
16213 last enabled row in the desired matrix touches the bottom boundary.
16215 2011-05-21 Glenn Morris <rgm@gnu.org>
16217 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
16218 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
16219 and add some more files.
16221 2011-05-20 Eli Zaretskii <eliz@gnu.org>
16223 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
16224 report_file_error introduced by the change from 2011-05-07.
16226 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
16228 * systime.h (Time): Define only if emacs is defined.
16229 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
16230 where the include path doesn't have X11/X.h by default. See
16231 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
16233 2011-05-20 Kenichi Handa <handa@m17n.org>
16235 * composite.c (find_automatic_composition): Fix previous change.
16237 2011-05-20 Glenn Morris <rgm@gnu.org>
16239 * lisp.mk: New file, split from Makefile.in.
16240 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
16241 (shortlisp): Remove.
16242 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
16244 2011-05-19 Glenn Morris <rgm@gnu.org>
16246 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
16247 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
16248 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
16249 (lisp): Set the order to that of loadup.el.
16250 (shortlisp): Make it a copy of $lisp.
16251 (SOME_MACHINE_LISP): Remove.
16252 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
16253 Use just $shortlisp, not $SOME_MACHINE_LISP too.
16255 2011-05-18 Kenichi Handa <handa@m17n.org>
16257 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
16258 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
16259 (find_automatic_composition): Mostly rewrite for efficiency.
16261 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
16263 * makefile.w32-in: Update dependencies.
16265 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
16267 * menu.c: Include limits.h (fixes the MS-Windows build broken by
16268 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
16270 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
16272 Fix some integer overflow issues, such as string length overflow.
16274 * insdel.c (count_size_as_multibyte): Check for string overflow.
16276 * character.c (lisp_string_width): Check for string overflow.
16277 Use EMACS_INT, not int, for string indexes and lengths; in
16278 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
16279 the resulting string length overflows an EMACS_INT; instead,
16280 report a string overflow if no precision given. When checking for
16281 precision exhaustion, use a check that cannot possibly have
16282 integer overflow. (Bug#8675)
16283 * character.h (lisp_string_width): Adjust to new signature.
16285 * alloc.c (string_overflow): New function.
16286 (Fmake_string): Use it. This doesn't change behavior, but saves
16287 a few bytes and will simplify future changes.
16288 * character.c (string_escape_byte8): Likewise.
16289 * lisp.h (string_overflow): New decl.
16291 Fixups, following up to the user-interface timestamp change.
16292 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
16293 for UI timestamps, instead of unsigned long.
16294 * msdos.c (mouse_get_pos): Likewise.
16295 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
16296 * w32gui.h (Time): Define by including "systime.h" rather than by
16297 declaring it ourselves. (Bug#8664)
16299 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
16300 * image.c (clear_image_cache): Likewise.
16302 * term.c (term_mouse_position): Don't assume time_t wraparound.
16304 Be more systematic about user-interface timestamps.
16305 Before, the code sometimes used 'Time', sometimes 'unsigned long',
16306 and sometimes 'EMACS_UINT', to represent these timestamps.
16307 This change causes it to use 'Time' uniformly, as that's what X uses.
16308 This makes the code easier to follow, and makes it easier to catch
16309 integer overflow bugs such as Bug#8664.
16310 * frame.c (Fmouse_position, Fmouse_pixel_position):
16311 Use Time, not unsigned long, for user-interface timestamps.
16312 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
16313 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
16314 * keyboard.h (last_event_timestamp): Likewise.
16315 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
16316 * menu.h (xmenu_show): Likewise.
16317 * term.c (term_mouse_position): Likewise.
16318 * termhooks.h (struct input_event.timestamp): Likewise.
16319 (struct terminal.mouse_position_hook): Likewise.
16320 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
16321 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
16322 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
16323 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
16324 what it was before.
16325 * menu.h, termhooks.h: Include "systime.h", for Time.
16327 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
16328 Don't assume that the difference between two unsigned long values
16329 can fit into an integer. At this point, we know button_down_time
16330 <= event->timestamp, so the difference must be nonnegative, so
16331 there's no need to cast the result if double-click-time is
16332 nonnegative, as it should be; check that it's nonnegative, just in
16333 case. This bug is triggered when events are more than 2**31 ms
16334 apart (about 25 days). (Bug#8664)
16336 * xselect.c (last_event_timestamp): Remove duplicate decl.
16337 (x_own_selection): Remove needless cast to unsigned long.
16339 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
16340 that always fit in int. Use a sentinel instead of a counter, to
16341 avoid a temp and to allay GCC's concerns about possible int overflow.
16342 * frame.h (struct frame): Use int for menu_bar_items_used
16343 instead of EMACS_INT, since it always fits in int.
16345 * menu.c (grow_menu_items): Check for int overflow.
16347 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
16349 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
16350 Before, the code was not consistent. These values cannot exceed
16351 2**31 - 1 so there's no need to make them unsigned.
16352 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
16353 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
16354 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
16356 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
16358 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
16359 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
16360 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
16361 presumably because the widths might not match.
16363 * window.c (size_window): Avoid needless test at loop start.
16365 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
16367 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
16369 2011-05-12 Drew Adams <drew.adams@oracle.com>
16371 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
16373 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16375 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
16376 `width' to `bar_area_x' and `bar_area_width', respectively.
16377 (x_scroll_run): Take account of fringe background extension.
16379 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
16380 Rename local vars `left' and `width' to `bar_area_x' and
16381 `bar_area_width', respectively.
16382 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
16383 background extension.
16385 2011-05-10 Jim Meyering <meyering@redhat.com>
16387 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
16389 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
16391 * image.c (Finit_image_library): Return t for built-in image types,
16392 like pbm and xbm. (Bug#8640)
16394 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
16396 * w32menu.c (set_frame_menubar): Fix submenu allocation.
16398 2011-05-07 Eli Zaretskii <eliz@gnu.org>
16400 * w32console.c (Fset_screen_color): Doc fix.
16401 (Fget_screen_color): New function.
16402 (syms_of_ntterm): Defsubr it.
16404 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
16405 unlink the temporary file if Fcall_process didn't create it in the
16407 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
16408 child process will be redirected to a file specified with `:file'.
16409 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
16410 cue to call_process_cleanup not to close that handle.
16412 2011-05-07 Ben Key <bkey76@gmail.com>
16414 * makefile.w32-in: The bootstrap-temacs rule now makes use of
16415 one of two shell specific rules, either bootstrap-temacs-CMD or
16416 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
16417 to the previous implementation of the bootstrap-temacs rule.
16418 The bootstrap-temacs-CMD rule is similar to the previous
16419 implementation of the bootstrap-temacs rule except that it
16420 makes use of the ESC_CFLAGS variable instead of the CFLAGS
16423 These changes, along with some changes to nt/configure.bat,
16424 nt/gmake.defs, and nt/nmake.defs, are required to extend my
16425 earlier fix to add support for --cflags and --ldflags options
16426 that include quotes so that it works whether make uses cmd or
16429 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
16431 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
16432 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
16434 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
16435 a string. Handle both cases.
16436 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
16437 (Fdbus_register_method): Use Qinvalid_function.
16439 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
16441 * makefile.w32-in: Update dependencies.
16442 (LISP_H): Add inttypes.h and stdin.h.
16443 (PROCESS_H): Add unistd.h.
16445 2011-05-06 Eli Zaretskii <eliz@gnu.org>
16447 * lread.c: Include limits.h (fixes the MS-Windows build broken by
16448 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
16450 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
16452 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
16454 * term.c (vfatal): Remove stray call to va_end.
16455 It's not needed and the C Standard doesn't allow it here anyway.
16457 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
16458 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
16460 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
16463 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
16465 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
16467 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
16469 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
16471 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
16473 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
16474 * charset.c (Fdefine_charset_internal): Don't initialize
16475 charset.code_space[15]. The value was garbage, on hosts with
16476 32-bit int (Bug#8600).
16478 * lread.c (read_integer): Be more consistent with string-to-number.
16479 Use string_to_number to do the actual conversion; this avoids
16480 rounding errors and fixes some other screwups. Without this fix,
16481 for example, #x1fffffffffffffff was misread as -2305843009213693952.
16482 (digit_to_number): Move earlier, for benefit of read_integer.
16483 Return -1 if the digit is out of range for the base, -2 if it is
16484 not a digit in any supported base. (Bug#8602)
16486 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
16488 * dispnew.c (scrolling_window): Return 1 if we scrolled,
16489 to match comment at start of function. This also removes a
16490 GCC warning about overflow in a 32+64-bit port.
16492 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
16494 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
16495 Reported by Stefan Monnier in
16496 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
16497 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
16498 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
16500 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
16501 (EMACS_UINTPTR): Likewise, with uintptr_t.
16503 * lisp.h: Prefer 64-bit EMACS_INT if available.
16504 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
16505 on 32-bit hosts that have 64-bit int, so that they can access
16507 However, temporarily disable this change unless the temporary
16508 symbol WIDE_EMACS_INT is defined.
16510 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
16512 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
16513 This removes an assumption that EMACS_INT and long are the same
16514 width as pointers. The assumption is true for Emacs porting targets
16515 now, but we want to make other targets possible.
16516 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
16517 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
16518 In the rest of the code, change types of integers that hold casted
16519 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
16520 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
16521 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
16522 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
16523 No need to cast type when ORing.
16524 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
16525 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
16526 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
16527 assume EMACS_INT is the same width as char *.
16528 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
16529 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
16530 Remove no-longer-needed casts.
16531 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
16532 (xg_tool_bar_help_callback, xg_make_tool_item):
16533 Use EMACS_INTPTR to hold an integer
16534 that will be cast to void *; this can avoid a GCC warning
16535 if EMACS_INT is not the same width as void *.
16536 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
16537 * xdisp.c (display_echo_area_1, resize_mini_window_1):
16538 (current_message_1, set_message_1):
16539 Use a local to convert to proper width without a cast.
16540 * xmenu.c (dialog_selection_callback): Likewise.
16542 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
16543 Also, don't assume VALBITS / RAND_BITS is less than 5,
16544 and don't rely on undefined behavior when shifting a 1 left into
16546 * lisp.h (get_random): Change signature to match.
16548 * lread.c (hash_string): Use size_t, not int, for hash computation.
16549 Normally we prefer signed values; but hashing is special, because
16550 it's better to use unsigned division on hash table sizes so that
16551 the remainder is nonnegative. Also, size_t is the natural width
16552 for hashing into memory. The previous code used 'int', which doesn't
16553 retain enough info to hash well into very large tables.
16554 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
16556 * dbusbind.c: Don't possibly lose pointer info when converting.
16557 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
16558 Use XPNTR rather than XHASH, so that the high-order bits of
16559 the pointer aren't lost when converting through void *.
16561 * eval.c (Fautoload): Don't double-shift a pointer.
16563 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.

16604 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.

16646 * process.c: Include lisp.h before w32.h, not after.
16647 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
16648 instead of gnutls_record_check_pending.
16650 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
16652 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
16654 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
16655 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
16658 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
16660 * xterm.c (x_set_frame_alpha): Do not set property on anything

16665 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
16667 2011-05-02 Juanma Barranquero <lekktu@gmail.com>

16695 (Fcall_process_region): Ditto.
16697 2011-04-30 Eli Zaretskii <eliz@gnu.org>
16699 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
16700 rather than `XVECTOR (FOO)->size'.
16702 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
16703 inttypes.h, as a gnulib replacement is used if it not available in
16706 2011-04-21 Eli Zaretskii <eliz@gnu.org>
16708 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
16709 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
16710 of MOST_POSITIVE_FIXNUM. (Bug#8528)
16712 * coding.c (coding_alloc_by_realloc): Error out if destination
16713 will grow beyond MOST_POSITIVE_FIXNUM.
16714 (decode_coding_emacs_mule): Abort if there isn't enough place in
16715 charbuf for the composition carryover bytes. Reserve an extra
16716 space for up to 2 characters produced in a loop.

16718 charbuf for the composition carryover bytes.
16720 2011-04-21 Eli Zaretskii <eliz@gnu.org>
16722 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
16723 aborting when %lld or %lll format is passed.
16724 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
16725 %llo or %llx format is passed. (Bug#8545)
16727 * window.c (window_scroll_line_based): Use a marker instead of
16728 simple variables to record original value of point. (Bug#7952)
16730 * doprnt.c (doprnt): Fix the case where a multibyte sequence
16731 produced by %s or %c overflows available buffer space. (Bug#8545)
16733 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
16735 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).

16745 (command_loop_1): Run `delayed-warnings-hook'
16746 if Vdelayed_warnings_list is non-nil.
16747 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
16748 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
16750 2011-04-28 Eli Zaretskii <eliz@gnu.org>
16752 * doprnt.c (doprnt): Don't return value smaller than the buffer
16753 size if the message was truncated. (Bug#8545).
16755 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
16757 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
16758 (Fx_window_property): #if-0 the whole functions, not just the bodies.
16760 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
16762 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
16764 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
16766 * makefile.w32-in: Update dependencies.
16768 2011-04-27 Eli Zaretskii <eliz@gnu.org>
16770 Improve `doprnt' and its usage. (Bug#8545)
16771 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
16772 `format_end'. Remove support for %l as a conversion specifier.
16773 Don't use xrealloc. Improve diagnostics when the %l size modifier
16774 is used. Update the commentary.
16776 * eval.c (verror): Simplify calculation of size_t.
16778 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
16781 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
16783 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
16786 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
16788 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
16789 This makes this file independent of the recent pseudovector change.
16791 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
16793 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
16795 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
16796 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
16797 Remove unused local.
16798 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
16800 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
16801 GCC 4.6.0 optimizes based on type-based alias analysis.
16802 For example, if b is of type struct buffer * and v of type struct
16803 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
16804 != &v->size, and therefore "v->size = 1; b->size = 2; return
16805 v->size;" must therefore return 1. This assumption is incorrect
16806 for Emacs, since it type-puns struct Lisp_Vector * with many other
16807 types. To fix this problem, this patch adds a new type struct
16808 vectorlike_header that documents the constraints on layout of vectors
16809 and pseudovectors, and helps optimizing compilers not get fooled
16810 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
16811 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
16812 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
16814 (XSETPVECTYPE): Rewrite in terms of new macro.
16815 (XSETPVECTYPESIZE): New macro, specifying both type and size.
16816 This is a bit clearer, and further avoids the possibility of
16817 undesirable aliasing.
16818 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
16819 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
16820 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
16821 since Lisp_Subr is a special case (no "next" field).
16822 (ASIZE): Now uses header.size rather than size.
16823 All previous uses of XVECTOR (foo)->size replaced to use this macro,
16824 to avoid the hassle of writing XVECTOR (foo)->header.size.
16825 (struct vectorlike_header): New type.
16826 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
16827 object, to help avoid aliasing.
16828 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
16829 (SUBRP): Likewise, since Lisp_Subr is a special case.
16830 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
16831 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
16832 (struct Lisp_Hash_Table): Combine first two members into a single
16833 struct vectorlike_header member. All uses of "size" and "next" members
16834 changed to be "header.size" and "header.next".
16835 * buffer.h (struct buffer): Likewise.
16836 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
16837 * frame.h (struct frame): Likewise.
16838 * process.h (struct Lisp_Process): Likewise.
16839 * termhooks.h (struct terminal): Likewise.
16840 * window.c (struct save_window_data, struct saved_window): Likewise.
16841 * window.h (struct window): Likewise.
16842 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
16843 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
16844 * buffer.c (init_buffer_once): Likewise.
16845 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
16847 * process.c (Fformat_network_address): Use local var for size,
16850 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
16852 Make the Lisp reader and string-to-float more consistent (Bug#8525)
16853 * data.c (atof): Remove decl; no longer used or needed.
16854 (digit_to_number): Move to lread.c.
16855 (Fstring_to_number): Use new string_to_number function, to be
16856 consistent with how the Lisp reader treats infinities and NaNs.
16857 Do not assume that floating-point numbers represent EMACS_INT
16858 without losing information; this is not true on most 64-bit hosts.
16859 Avoid double-rounding errors, by insisting on integers when
16860 parsing non-base-10 numbers, as the documentation specifies.
16861 * lisp.h (string_to_number): New decl, replacing ...
16862 (isfloat_string): Remove.
16863 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
16864 (read1): Do not accept +. and -. as integers; this
16865 appears to have been a coding error. Similarly, do not accept
16866 strings like +-1e0 as floating point numbers. Do not report
16867 overflow for integer overflows unless the base is not 10 which
16868 means we have no simple and reliable way to continue.
16869 Break out the floating-point parsing into a new
16870 function string_to_number, so that Fstring_to_number parses
16871 floating point numbers consistently with the Lisp reader.
16872 (digit_to_number): Move here from data.c. Make it static inline.
16873 (E_CHAR, EXP_INT): Remove, replacing with ...
16874 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
16875 (string_to_number): New function, replacing isfloat_string.
16876 This function checks for valid syntax and produces the resulting
16877 Lisp float number too. Rework it so that string-to-number
16878 no longer mishandles examples like "1.0e+". Use strtoumax,
16879 so that overflow for non-base-10 numbers is reported only when
16880 there's no portable and simple way to convert to floating point.
16882 * textprop.c (set_text_properties_1): Rewrite for clarity,
16883 and to avoid GCC warning about integer overflow.
16885 * intervals.h (struct interval): Use EMACS_INT for members
16886 where EMACS_UINT might cause problems. See
16887 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
16888 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
16889 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
16891 (offset_intervals): Tell GCC not to worry about length overflow
16892 when negating a negative length.
16894 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
16895 (overrun_check_free): Likewise.
16897 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
16898 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
16901 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
16902 (gnutls_make_error): Rename local to avoid shadowing.
16903 (gnutls_emacs_global_deinit): ifdef out; not used.
16904 (Fgnutls_boot): Use const for pointer to readonly storage.
16905 Comment out unused local. Fix pointer signedness problems.
16907 * lread.c (openp): Don't stuff size_t into an 'int'.
16908 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
16909 about possible signed overflow.
16911 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
16912 (GDK_KEY_g): Don't define if already defined.
16913 (xg_prepare_tooltip): Avoid pointer signedness problem.
16914 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
16916 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
16917 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
16919 * xfns.c (Fx_window_property): Simplify a bit,
16920 to make a bit faster and to avoid GCC 4.6.0 warning.
16921 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
16923 * fns.c (internal_equal): Don't assume size_t fits in int.
16925 * alloc.c (compact_small_strings): Tighten assertion a little.
16927 Replace pEd with more-general pI, and fix some printf arg casts.
16928 * lisp.h (pI): New macro, generalizing old pEd macro to other
16929 conversion specifiers. For example, use "...%"pI"d..." rather
16930 than "...%"pEd"...".
16931 (pEd): Remove. All uses replaced with similar uses of pI.
16932 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
16933 * alloc.c (check_pure_size): Don't overflow by converting size to int.
16934 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
16935 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
16936 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
16937 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
16938 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
16940 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
16941 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
16942 * print.c (safe_debug_print, print_object): Likewise.
16943 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
16945 Use pI instead of if-then-else-abort. Use %p to avoid casts,
16946 avoiding the 0 flag, which is not portable.
16947 * process.c (Fmake_network_process): Use pI to avoid cast.
16948 * region-cache.c (pp_cache): Likewise.
16949 * xdisp.c (decode_mode_spec): Likewise.
16950 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
16951 behavior on 64-bit hosts with printf arg.

16953 (x_stop_queuing_selection_requests): Likewise.
16954 (x_get_window_property): Don't truncate byte count to an 'int'
16957 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
16958 here, since it parses constructs like leading '-' and spaces,
16959 which are not wanted; and it overflows with large numbers.
16960 Instead, simply match F[0-9]+, which is what is wanted anyway.
16962 * alloc.c: Remove unportable assumptions about struct layout.
16963 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
16964 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
16965 (allocate_vectorlike, make_pure_vector): Use the new macros,
16966 plus offsetof, to remove unportable assumptions about struct layout.
16967 These assumptions hold on all porting targets that I know of, but
16968 they are not guaranteed, they're easy to remove, and removing them
16969 makes further changes easier.
16971 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
16972 This doesn't fix a bug but makes the code clearer.
16973 (string_overrun_cookie): Now const. Use initializers that
16974 don't formally overflow signed char, to avoid warnings.
16975 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
16976 can cause Emacs to crash when string overrun checking is enabled.
16977 (allocate_buffer): Don't assume sizeof (struct buffer) is a
16978 multiple of sizeof (EMACS_INT); it need not be, if
16979 alignof(EMACS_INT) < sizeof (EMACS_INT).
16980 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
16982 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

17011 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
17012 "cast to pointer from integer of different size".
17014 Improve doprnt and its use in verror. (Bug#8545)
17015 * doprnt.c (doprnt): Document the set of format control sequences
17016 supported by the function. Use SAFE_ALLOCA instead of always
17019 * eval.c (verror): Don't limit the buffer size at size_max-1, that
17020 is one byte too soon. Don't use xrealloc; instead xfree and
17023 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
17025 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the

17031 parameters of `gnutls-boot' and documented those parameters in the
17032 docstring. Start callback support.
17033 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
17034 unless a fatal error occurred. Call gnutls_alert_send_appropriate

17132 * callint.c (Fcall_interactively): When displaying error message
17133 about invalid control letter, pass the character's codepoint, not

17138 codepoint of an invalid character, to avoid displaying a bogus
17141 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
17142 `error', not SYMBOL_NAME itself.
17144 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
17145 character arguments to `error'.
17147 * charset.c (check_iso_charset_parameter): Fix incorrect argument
17148 to `error' in error message about FINAL_CHAR argument. Make sure
17149 FINAL_CHAR is a character, and use %c when it is passed as
17150 argument to `error'.
17152 2011-04-23 Eli Zaretskii <eliz@gnu.org>
17154 * s/ms-w32.h (localtime): Redirect to sys_localtime.
17156 * w32.c: Include <time.h>.

17216 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
17217 by pacifying GCC about it. Maybe it's time to retire it?
17218 * xfaces.c (USG, __TIMEVAL__): Likewise.
17220 * dispextern.h (struct redisplay_interface): Rename param
17221 to avoid shadowing.
17222 * termhooks.h (struct terminal): Likewise.
17223 * xterm.c (xembed_send_message): Likewise.

17339 * nsfont.m: Fixed bugs in ns_get_family and
17340 ns_descriptor_to_entity that were caused by using free to
17341 deallocate memory blocks that were allocated by xmalloc (via
17342 xstrdup). This caused Emacs to crash when compiled with
17343 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
17344 --enable-checking=xmallocoverrun). xfree is now used to
17345 deallocate these memory blocks.

17359 (emacs_read, emacs_write): Remove check for negative size, as the
17360 Emacs source code has been audited now.
17361 * sysdep.c (MAX_RW_COUNT): New macro, to work around kernel bugs.
17362 (emacs_read, emacs_write): Use it.
17363 * process.c (send_process): Adjust to the new signatures of
17364 emacs_write and emacs_gnutls_write. Do not attempt to store
17365 a byte offset into an 'int'; it might overflow.
17366 See http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00483.html

17392 2011-04-14 Paul Eggert <eggert@cs.ucla.edu>
17394 Improve C-level modularity by making more things 'static'.
17396 Don't publish debugger-only interfaces to other modules.

17818 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
17820 * charset.c (Fclear_charset_maps): Use xfree instead of free.
17822 * keyboard.c (parse_tool_bar_item): Likewise.
17823 * sound.c (sound_cleanup, alsa_close): Likewise.
17824 * termcap.c (tgetent): Likewise.
17825 * xfns.c (x_default_font_parameter): Likewise.
17826 * xsettings.c (read_and_apply_settings): Likewise.
17828 * alloc.c (overrun_check_malloc, overrun_check_realloc)
17829 (overrun_check_free): Protoize.
17831 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
17833 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
17834 since callers should never pass a negative size.
17835 Change the signature to match that of plain 'read' and 'write'; see
17836 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
17837 * lisp.h: Update prototypes of emacs_write and emacs_read.
17839 2011-04-11 Eli Zaretskii <eliz@gnu.org>
17841 * xdisp.c (redisplay_window): Don't try to determine the character
17842 position of the scroll margin if the window start point w->startp
17843 is outside the buffer's accessible region. (Bug#8468)
17845 2011-04-10 Eli Zaretskii <eliz@gnu.org>
17847 Fix write-region and its subroutines for buffers > 2GB.
17848 * fileio.c (a_write, e_write): Modify declaration of arguments and
17849 local variables to support buffers larger than 2GB.
17850 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
17852 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
17853 argument, local variables, and return value.
17855 * lisp.h: Update prototypes of emacs_write and emacs_read.
17857 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
17859 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
17861 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
17863 Fix more problems found by GCC 4.6.0's static checks.
17865 * xdisp.c (vmessage): Use a better test for character truncation.
17867 * charset.c (load_charset_map): <, not <=, for optimization,
17868 and to avoid potential problems with integer overflow.
17869 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
17870 * casetab.c (set_identity, shuffle): Likewise.
17871 * editfns.c (Fformat): Likewise.
17872 * syntax.c (skip_chars): Likewise.
17874 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
17875 This also lets GCC 4.6.0 generate slightly better loop code.
17877 * callint.c (Fcall_interactively): <, not <=, for optimization.
17878 (Fcall_interactively): Count the number of arguments produced,
17879 not the number of arguments given. This is simpler and lets GCC
17880 4.6.0 generate slightly better code.
17882 * ftfont.c: Distingish more carefully between FcChar8 and char.
17883 The previous code passed unsigned char * to a functions like
17884 strlen and xstrcasecmp that expect char *, which does not
17885 conform to the C standard.
17886 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
17887 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
17888 char * when the C standard requires it.
17890 * keyboard.c (read_char): Remove unused var.
17892 * eval.c: Port to Windows vsnprintf (Bug#8435).
17893 Include <limits.h>.
17894 (SIZE_MAX): Define if the headers do not.
17895 (verror): Do not give up if vsnprintf returns a negative count.
17896 Instead, grow the buffer. This ports to Windows vsnprintf, which
17897 does not conform to C99. Problem reported by Eli Zaretskii.
17898 Also, simplify the allocation scheme, by avoiding the need for
17899 calling realloc, and removing the ALLOCATED variable.
17901 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
17903 Remove invocations of doprnt, as Emacs now uses vsnprintf.
17904 But keep the doprint source code for now, as we might revamp it
17905 and use it again (Bug#8435).
17906 * lisp.h (doprnt): Remove.
17907 * Makefile.in (base_obj): Remove doprnt.o.
17908 * deps.mk (doprnt.o): Remove.
17910 error: Print 32- and 64-bit integers portably (Bug#8435).
17911 Without this change, on typical 64-bit hosts error ("...%d...", N)
17912 was used to print both 32- and 64-bit integers N, which relied on
17913 undefined behavior.
17914 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
17915 * lisp.h (error, verror): Mark as printf-like functions.
17916 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
17917 Report overflow in size calculations when allocating printf buffer.
17918 Do not truncate output string at its first null byte.
17919 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
17920 Truncate the output at a character boundary, since vsnprintf does not
17922 * charset.c (check_iso_charset_parameter): Convert internal
17923 character to string before calling 'error', since %c now has the
17925 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
17926 overflow when computing char to be passed to 'error'. Do not
17927 pass Lisp_Object to 'error'; pass the integer instead.
17928 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
17929 formatted with plain %d.
17931 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
17933 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
17935 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
17937 * xterm.c (x_catch_errors): Remove duplicate declaration.
17939 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
17941 * xdisp.c, lisp.h (message_nolog): Remove; unused.
17943 2011-04-10 Jim Meyering <meyering@redhat.com>
17945 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
17946 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
17947 return ssize_t not "int", and use size_t as the buffer length.
17948 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
17949 * gnutls.h: Update declarations.
17950 * process.c (read_process_output): Use ssize_t, to match.
17951 (send_process): Likewise.
17953 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
17955 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
17957 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
17959 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
17960 Use unsigned char, to match FcChar8 type definition.
17962 * xterm.c (handle_one_xevent):
17963 * xmenu.c (create_and_show_popup_menu):
17964 * xselect.c (x_decline_selection_request)
17965 (x_reply_selection_request): Avoid type-punned deref of X events.
17967 2011-04-09 Eli Zaretskii <eliz@gnu.org>
17969 Fix some uses of `int' instead of EMACS_INT.
17970 * search.c (string_match_1, fast_string_match)
17971 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
17972 (scan_buffer, find_next_newline_no_quit)
17973 (find_before_next_newline, search_command, Freplace_match)
17974 (Fmatch_data): Make some `int' variables be EMACS_INT.
17976 * xdisp.c (display_count_lines): 3rd argument and return value now
17977 EMACS_INT. All callers changed.
17978 (pint2hrstr): Last argument is now EMACS_INT.
17980 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
17981 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
17982 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
17983 (decode_coding_utf_16, decode_coding_emacs_mule)
17984 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
17985 (decode_coding_ccl, decode_coding_charset)
17986 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
17987 (decode_coding_iso_2022, decode_coding_emacs_mule)
17988 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
17989 <char_offset, last_offset>: Declare EMACS_INT.
17990 (encode_coding_utf_8, encode_coding_utf_16)
17991 (encode_coding_emacs_mule, encode_invocation_designation)
17992 (encode_designation_at_bol, encode_coding_iso_2022)
17993 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
17994 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
17996 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
17997 (encode_invocation_designation): Last argument P_NCHARS is now
17999 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
18000 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
18002 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
18005 * ccl.c (Fccl_execute_on_string): Declare some variables
18008 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
18010 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
18012 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
18014 * process.c (Fformat_network_address): Doc fix.
18016 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
18018 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
18020 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
18022 * keyboard.c (read_char): Call Lisp function help-form-show,
18023 instead of using internal_with_output_to_temp_buffer.
18024 (Qhelp_form_show): New var.
18025 (syms_of_keyboard): Use DEFSYM macro.
18027 * print.c (internal_with_output_to_temp_buffer): Function deleted.
18029 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
18031 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
18033 * process.c (Flist_processes): Remove to Lisp.
18034 (list_processes_1): Delete.
18036 2011-04-06 Eli Zaretskii <eliz@gnu.org>
18038 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
18040 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
18042 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
18044 Fix more problems found by GCC 4.6.0's static checks.
18046 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
18048 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
18050 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
18052 * xdisp.c (vmessage): Mark as a printf-like function.
18054 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
18056 * sound.c (sound_warning): Don't crash if arg contains a printf format.
18058 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
18059 printf-like functions.
18060 (tiff_load): Add casts to remove these marks before passing them
18061 to system-supplied API.
18063 * eval.c (Fsignal): Remove excess argument to 'fatal'.
18065 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
18066 This avoids several warnings with gcc -Wstrict-overflow.
18067 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
18068 directly, rather than having caller test rule sign. This avoids
18069 some unnecessary tests.
18070 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
18071 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
18072 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
18074 * xfont.c (xfont_text_extents): Remove var that was set but not used.
18075 (xfont_open): Avoid unnecessary tests.
18077 * composite.c (composition_gstring_put_cache): Use unsigned integer.
18079 * composite.h, composite.c (composition_gstring_put_cache):
18080 Use EMACS_INT, not int, for length.
18082 * composite.h (COMPOSITION_DECODE_REFS): New macro,
18083 breaking out part of COMPOSITION_DECODE_RULE.
18084 (COMPOSITION_DECODE_RULE): Use it.
18085 * composite.c (get_composition_id): Remove unused local vars,
18086 by using the new macro.
18088 * textprop.c (set_text_properties_1): Change while to do-while,
18089 since the condition is always true at first.
18091 * intervals.c (graft_intervals_into_buffer): Mark var as used.
18092 (interval_deletion_adjustment): Return unsigned value.
18095 * process.c (list_processes_1, create_pty, read_process_output):
18096 (exec_sentinel): Remove vars that were set but not used.
18097 (create_pty): Remove unnecessary "volatile"s.
18098 (Fnetwork_interface_info): Avoid possibility of int overflow.

18105 (update_syntax_table): Use unsigned instead of int.
18107 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
18108 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
18109 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
18111 * print.c (print_error_message): Avoid int overflow.
18113 * font.c (font_list_entities): Redo for clarity,
18114 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
18116 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
18117 (font_score): Avoid potential overflow in diff calculation.
18119 * fns.c (substring_both): Remove var that is set but not used.
18120 (sxhash): Redo loop for clarity and to avoid wraparound warning.
18122 * eval.c (funcall_lambda): Rename local to avoid shadowing.
18124 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
18125 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
18126 can always succeed if overflow has undefined behavior.
18128 * search.c (boyer_moore, wordify): Remove vars set but not used.
18129 (wordify): Omit three unnecessary tests.
18131 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
18132 All callers changed. This avoids the need for an unused var.
18134 * casefiddle.c (casify_region): Remove var that is set but not used.
18136 * dired.c (file_name_completion): Remove var that is set but not used.
18138 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
18140 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
18141 (Finsert_file_contents): Remove unnecessary code checking fd.
18143 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
18144 Check for integer overflow on size calculations.
18146 * buffer.c (Fprevious_overlay_change): Remove var that is set
18149 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
18150 Remove vars that are set but not used.
18151 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
18152 (timer_check_2): Mark vars as initialized.
18154 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
18156 * image.c (lookup_image): Remove var that is set but not used.
18157 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
18159 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
18160 that are set but not used.
18162 * xfns.c (make_invisible_cursor): Don't return garbage
18163 if XCreateBitmapFromData fails (Bug#8410).
18165 * xselect.c (x_get_local_selection, x_handle_property_notify):
18166 Remove vars that are set but not used.
18168 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
18169 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
18171 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
18172 Remove var that is set but not used.

18174 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
18175 Check for overflow.
18177 * xfaces.c (realize_named_face): Remove vars that are set but not used.
18178 (map_tty_color) [!defined MSDOS]: Likewise.
18180 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
18182 * coding.c: Remove vars that are set but not used.
18183 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
18184 All callers changed.
18185 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
18186 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
18187 (decode_coding_charset): Remove vars that are set but not used.
18189 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
18190 that is set but not used.
18192 * print.c (print_object): Remove var that is set but not used.
18194 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
18195 The gnulib version avoids calling malloc in the usual case,
18196 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
18197 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
18198 * filelock.c (current_lock_owner): Likewise.
18199 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
18200 * sysdep.c: Include allocator.h, careadlinkat.h.
18201 (emacs_no_realloc_allocator): New static constant.
18202 (emacs_readlink): New function.
18203 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
18204 ../lib/careadlinkat.h.
18206 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
18208 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
18209 first non-nil return value).
18211 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
18213 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
18214 if not defined (Bug#8403).

18218 * xdisp.c (display_count_lines): Remove parameter `start',
18219 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
18220 (get_char_face_and_encoding): Remove parameter `multibyte_p',
18221 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

18223 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
18224 and thereabouts. All callers changed.
18225 (get_per_char_metric): Remove parameter `f', unused since
18226 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
18228 2011-04-02 Jim Meyering <meyering@redhat.com>
18230 do not dereference NULL upon failed strdup
18231 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
18232 (ns_get_family): Likewise.
18234 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
18236 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
18238 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
18240 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or

18273 (Fcommandp): Handle closures.
18274 (Feval): New `lexical' arg.
18275 (eval_sub): New function extracted from Feval. Use it almost
18276 everywhere where Feval was used. Look up vars in lexical env.
18278 (Ffunctionp): Move from subr.el.
18279 (Ffuncall): Handle closures.
18280 (apply_lambda): Remove `eval_flags'.
18281 (funcall_lambda): Handle closures and new byte-code-functions.
18282 (Fspecial_variable_p): New function.
18283 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
18284 but without exporting it to Lisp.
18286 * doc.c (Fdocumentation, store_function_docstring):
18287 * data.c (Finteractive_form): Handle closures.
18289 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
18292 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
18294 (exec_byte_code): New function extracted from Fbyte_code to handle new
18295 calling convention for byte-code-functions. Add new byte-codes.
18297 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
18299 * alloc.c (Fmake_symbol): Init new `declared_special' field.
18301 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
18303 * xdisp.c (redisplay_internal): Fix prototype.
18305 2011-03-31 Eli Zaretskii <eliz@gnu.org>
18307 * xdisp.c (SCROLL_LIMIT): New macro.
18308 (try_scrolling): Use it when setting scroll_limit.
18309 Limit scrolling to 100 screen lines.
18310 (redisplay_window): Even when falling back on "recentering",
18311 position point in the window according to scroll-conservatively,
18312 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
18314 (try_scrolling): When point is above the window, allow searching
18315 as far as scroll_max, or one screenful, to compute vertical
18316 distance from PT to the scroll margin position. This prevents
18317 try_scrolling from unnecessarily failing when
18318 scroll-conservatively is set to a value slightly larger than the
18319 window height. Clean up the case of PT below the margin at bottom
18320 of window: scroll_max can no longer be INT_MAX. When aggressive
18321 scrolling is in use, don't let point enter the opposite scroll
18322 margin as result of the scroll.
18323 (syms_of_xdisp) <scroll-conservatively>: Document the
18324 threshold of 100 lines for never-recentering scrolling.
18326 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
18328 * dispextern.h (move_it_by_lines):
18329 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
18330 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
18331 (message_log_check_duplicate): Remove parameters `prev_bol' and
18332 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
18333 (redisplay_internal): Remove parameter `preserve_echo_area',
18334 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
18336 * indent.c (Fvertical_motion):
18337 * window.c (window_scroll_pixel_based, Frecenter):
18338 Don't pass `need_y_p' to `move_it_by_lines'.
18340 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
18342 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
18343 steal a few bits to be more compact.
18344 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
18345 Remove unneeded casts.
18347 * bytecode.c (Fbyte_code): CAR and CDR can GC.
18349 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
18351 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
18352 binding" message (bug#7967).
18354 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
18356 Fix more problems found by GCC 4.6.0's static checks.
18358 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
18359 Remove unused local var.
18361 * editfns.c (Fmessage_box): Remove unused local var.
18363 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
18364 (note_mode_line_or_margin_highlight, note_mouse_highlight):
18365 Omit unused local vars.
18366 * window.c (shrink_windows): Omit unused local var.
18367 * menu.c (digest_single_submenu): Omit unused local var.
18368 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
18369 Omit unused local var.
18371 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
18372 Don't assume string length fits in int.
18373 (keyremap_step, read_key_sequence): Use size_t for sizes.
18374 (read_key_sequence): Don't check last_real_key_start redundantly.
18376 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
18377 instead of alloca (Bug#8344).
18379 * eval.c (Fbacktrace): Don't assume nargs fits in int.
18380 (Fbacktrace_frame): Don't assume nframes fits in int.
18382 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
18384 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
18387 * term.c (produce_glyphless_glyph): Remove unnecessary test.
18389 * cm.c (calccost): Turn while-do into do-while, for clarity.
18391 * keyboard.c (syms_of_keyboard): Use the same style as later
18392 in this function when indexing through an array. This also
18393 works around GCC bug 48267.
18395 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
18397 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
18399 * chartab.c (sub_char_table_ref_and_range): Redo for slight
18400 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
18402 * keyboard.c, keyboard.h (num_input_events): Now size_t.
18403 This avoids undefined behavior on integer overflow, and is a bit
18404 more convenient anyway since it is compared to a size_t variable.
18406 Variadic C functions now count arguments with size_t, not int.
18407 This avoids an unnecessary limitation on 64-bit machines, which
18408 caused (substring ...) to crash on large vectors (Bug#8344).
18409 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
18410 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
18411 All variadic functions and their callers changed accordingly.
18412 (struct gcpro.nvars): Now size_t, not int. All uses changed.

18414 * editfns.c (general_insert_function): Likewise.
18415 * eval.c (struct backtrace.nargs, interactive_p)
18416 (internal_condition_case_n, run_hook_with_args, apply_lambda)
18417 (funcall_lambda, mark_backtrace): Likewise.
18418 * fns.c (concat): Likewise.
18419 * frame.c (x_set_frame_parameters): Likewise.
18420 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
18421 0 if not found, not -1. All callers changed.
18423 * alloc.c (garbage_collect): Don't assume stack size fits in int.
18424 (stack_copy_size): Now size_t, not int.
18425 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
18427 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
18429 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
18430 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
18431 All callers changed.
18433 * lisp.h (multibyte_char_to_unibyte):
18434 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
18435 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
18436 * character.h (CHAR_TO_BYTE8):
18437 * cmds.c (internal_self_insert):
18438 * editfns.c (general_insert_function):
18439 * keymap.c (push_key_description):
18440 * search.c (Freplace_match):
18441 * xdisp.c (message_dolog, set_message_1): All callers changed.
18443 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
18445 * keyboard.c (safe_run_hook_funcall): New function.
18446 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
18447 don't set the hook to nil, but remove the offending function instead.
18448 (Qcommand_hook_internal): Remove, unused.
18449 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
18450 Vcommand_hook_internal.
18452 * eval.c (enum run_hooks_condition): Remove.
18453 (funcall_nil, funcall_not): New functions.
18454 (run_hook_with_args): Call each function through a `funcall' argument.
18455 Remove `cond' argument, now redundant.
18456 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
18457 (Frun_hook_with_args_until_failure): Adjust accordingly.
18458 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
18460 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
18462 * dispextern.h (string_buffer_position): Remove declaration.
18464 * print.c (strout): Remove parameter `multibyte', unused since
18465 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
18467 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
18468 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
18469 All callers changed.
18471 * w32.c (_wsa_errlist): Use braces for struct initializers.
18473 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
18474 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
18475 All callers changed.
18476 (string_buffer_position): Likewise. Also, make static (it's never
18477 used outside xdisp.c).
18478 (cursor_row_p): Remove parameter `w', unused since
18479 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.

18481 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
18482 All callers changed.
18484 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
18486 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.
18488 2011-03-27 Anders Lindgren <andlind@gmail.com>
18490 * nsterm.m (ns_menu_bar_is_hidden): New variable.
18491 (ns_constrain_all_frames, ns_menu_bar_should_be_hidden)
18492 (ns_update_auto_hide_menu_bar): New functions.
18493 (ns_update_begin): Call ns_update_auto_hide_menu_bar.
18494 (applicationDidBecomeActive): Call ns_update_auto_hide_menu_bar and

18497 (syms_of_nsterm): DEFVAR ns-auto-hide-menu-bar, init to Qnil.
18499 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
18501 * nsmenu.m (runDialogAt): Remove argument to timer_check.
18503 2011-03-27 Glenn Morris <rgm@gnu.org>
18505 * syssignal.h: Replace RETSIGTYPE with void.
18506 * atimer.c, data.c, dispnew.c, emacs.c, floatfns.c, keyboard.c:
18507 * keyboard.h, lisp.h, process.c, sysdep.c, xterm.c:
18508 Replace SIGTYPE with void everywhere.
18509 * s/usg5-4-common.h (SIGTYPE): Remove definition.
18510 * s/template.h (SIGTYPE): Remove commented out definition.
18512 2011-03-26 Eli Zaretskii <eliz@gnu.org>
18514 * xdisp.c (redisplay_window): Don't check buffer's clip_changed
18515 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
18517 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
18519 * w32.c (read_unc_volume): Use parameter `henum', instead of
18520 global variable `wget_enum_handle'.
18522 * keymap.c (describe_vector): Remove parameters `indices' and
18523 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.

18526 * keyboard.h (timer_check, show_help_echo): Remove unused parameters.
18528 * keyboard.c (timer_check): Remove parameter `do_it_now',
18529 unused since 1996-04-12T06:01:29Z!rms@gnu.org.
18530 (show_help_echo): Remove parameter `ok_to_overwrite_keystroke_echo',
18531 unused since 2008-04-19T19:30:53Z!monnier@iro.umontreal.ca.
18533 * keyboard.c (read_char):
18534 * w32menu.c (w32_menu_display_help):
18535 * xmenu.c (show_help_event, menu_help_callback):
18536 Adjust calls to `show_help_echo'.
18538 * gtkutil.c (xg_maybe_add_timer):
18539 * keyboard.c (readable_events):
18540 * process.c (wait_reading_process_output):
18541 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
18543 * insdel.c (adjust_markers_gap_motion):
18544 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.
18545 (gap_left, gap_right): Don't call it.
18547 2011-03-25 Chong Yidong <cyd@stupidchicken.com>
18549 * xdisp.c (handle_fontified_prop): Discard changes to clip_changed
18550 incurred during fontification.

18591 2011-03-24 Juanma Barranquero <lekktu@gmail.com>
18593 * w32term.c (x_set_glyph_string_clipping):
18594 Don't pass uninitialized region to CombineRgn.
18596 2011-03-23 Juanma Barranquero <lekktu@gmail.com>
18598 * w32fns.c (x_set_menu_bar_lines): Remove unused variable `olines'.
18599 (w32_wnd_proc): Pass NULL to Windows API, not uninitialized buffer.
18600 (Fx_close_connection): Remove unused variable `i'.
18602 * w32font.c (w32font_draw): Return number of glyphs.

18616 (uniscribe_font_driver): Add missing initializers.
18618 2011-03-23 Julien Danjou <julien@danjou.info>
18620 * term.c (Fsuspend_tty, Fresume_tty):
18621 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
18622 * window.c (temp_output_buffer_show):
18623 * insdel.c (signal_before_change):
18624 * frame.c (Fhandle_switch_frame):
18625 * fileio.c (Fdo_auto_save):
18626 * emacs.c (Fkill_emacs):
18627 * editfns.c (save_excursion_restore):
18628 * cmds.c (internal_self_insert):
18629 * callint.c (Fcall_interactively):
18630 * buffer.c (Fkill_all_local_variables):
18631 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
18633 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
18634 unconditionally since it does the check itself.
18636 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
18638 Fix more problems found by GCC 4.5.2's static checks.
18640 * coding.c (encode_coding_raw_text): Avoid unnecessary test
18641 the first time through the loop, since we know p0 < p1 then.
18642 This also avoids a gcc -Wstrict-overflow warning.
18644 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
18645 leading to a memory leak, possible in functions like
18646 load_charset_map_from_file that can allocate an unbounded number
18647 of objects (Bug#8318).
18649 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
18650 that could (at least in theory) be that large.
18652 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
18653 This is less likely to overflow, and avoids undefined behavior if
18654 overflow does occur. All callers changed. Use strtoul to scan
18655 for the unsigned long integer.
18656 (pint2hrstr): Simplify and tune code slightly.
18657 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
18659 * scroll.c (do_scrolling): Work around GCC bug 48228.
18660 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
18662 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
18663 This also avoids a warning with gcc -Wstrict-overflow.
18664 (validate_x_resource_name): Simplify count usage.
18665 This also avoids a warning with gcc -Wstrict-overflow.
18667 * fileio.c (Fcopy_file): Report error if fchown or fchmod
18670 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
18672 * process.c (Fmake_network_process): Use socklen_t, not int,
18673 where POSIX says socklen_t is required in portable programs.
18674 This fixes a porting bug on hosts like 64-bit HP-UX, where
18675 socklen_t is wider than int (Bug#8277).
18676 (Fmake_network_process, server_accept_connection):
18677 (wait_reading_process_output, read_process_output):
18680 * process.c: Rename or move locals to avoid shadowing.
18681 (list_processes_1, Fmake_network_process):
18682 (read_process_output_error_handler, exec_sentinel_error_handler):
18683 Rename or move locals.
18684 (Fmake_network_process): Define label "retry_connect" only if needed.
18685 (Fnetwork_interface_info): Fix pointer signedness.
18686 (process_send_signal): Add cast to avoid pointer signedness problem.
18687 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
18688 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
18690 Make tparam.h and terminfo.c consistent.
18691 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
18692 Include tparam.h instead, since it declares them.
18693 * cm.h (PC): Remove extern decl; tparam.h now does this.
18694 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
18695 * terminfo.c: Include tparam.h, to check interfaces.
18696 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
18697 (tparam): Adjust signature to match interface in tparam.h;
18698 this removes some undefined behavior. Check that outstring and len
18699 are zero, which they always are with Emacs.
18700 * tparam.h (PC, BC, UP): New extern decls.
18702 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
18703 (xftfont_open): Rename locals to avoid shadowing.
18705 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
18706 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.

18754 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
18756 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
18757 This should get cleaned up, so that child_setup has the
18758 same signature on all platforms.

18930 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
18931 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
18932 to use the following functions instead of these macros.
18933 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
18934 EMACS_INT, since callers assume the returned value fits in int.
18935 (upcase1): Likewise, for UPCASE_TABLE.
18936 (uppercasep, lowercasep, upcase): New static inline functions.
18937 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

18948 (RETALLOC_IF): Define only if needed.
18949 (WORDCHAR_P): Likewise. This one is never needed, but is used
18950 only in a comment talking about a compiler bug, so put inside
18951 the #if 0 of that comment.
18952 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
18953 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

18980 New macros, so that the caller can use some names other than
18981 gcpro1, gcpro2, etc.
18982 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
18984 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
18985 argument, for consistency with GCPRO2_VAR, etc: it is now the
18986 prefix of the variable, not the variable itself. All uses
18988 * dired.c (directory_files_internal, file_name_completion):
18989 Rename locals to avoid shadowing.
18991 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
18992 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
18993 dired.c's scmp function, had undefined behavior.
18994 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
18995 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
18996 * buffer.h: ... to here, because these macros use current_buffer,
18997 and the new implementation with inline functions needs to have
18998 current_buffer in scope now, rather than later when the macros
19000 (downcase, upcase1): New static inline functions.
19001 (DOWNCASE, UPCASE1): Reimplement using these functions.
19002 This avoids undefined behavior in expressions like
19003 DOWNCASE (x) == DOWNCASE (y), which previously suffered
19004 from race conditions in accessing the global variables
19005 case_temp1 and case_temp2.
19006 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
19007 * lisp.h (case_temp1, case_temp2): Remove their decls.
19008 * character.h (ASCII_CHAR_P): Move from here ...
19009 * lisp.h: ... to here, so that the inline functions mentioned
19010 above can use them.
19012 * dired.c (directory_files_internal_unwind): Now static.
19014 * fileio.c (file_name_as_directory, directory_file_name):

19017 (file_name_as_directory): Use const pointers when appropriate.
19018 (Fexpand_file_name): Likewise. In particular, newdir might
19019 point at constant storage, so make it a const pointer.

19021 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
19023 (Fset_file_times, Finsert_file_contents, auto_save_error):

19028 to avoid shadowing.
19030 * marker.c (bytepos_to_charpos): Remove; unused.
19032 * lisp.h (verify_bytepos, count_markers): New decls,
19033 so that gcc does not warn that these functions aren't declared.

19036 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
19037 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
19038 (copy_text): Remove unused local var.

19043 * buffer.c (fix_overlays_before): Mark locals as initialized.
19044 (fix_start_end_in_overlays): Likewise. This function should be
19045 simplified by using pointers-to-pointers, but that's a different
19047 (switch_to_buffer_1): Now static.
19048 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
19049 (report_overlay_modification): Rename locals to avoid shadowing.

19052 Fix pointer signedness issue.
19053 (sys_subshell): Mark local as volatile if checking for lint,
19054 to suppress a gcc -Wclobbered warning that does not seem to be right.
19055 (MAXPATHLEN): Define only if needed.
19057 * process.c (serial_open, serial_configure): Move decls from here ...
19058 * systty.h: ... to here, so that they can be checked.
19060 * fns.c (get_random, seed_random): Move extern decls from here ...
19061 * lisp.h: ... to here, so that they can be checked.
19063 * sysdep.c (reset_io): Now static.
