1 2012-12-04 Eli Zaretskii <eliz@gnu.org>
3 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
4 Encode the file name before passing it to dostounix_filename, in
5 case it will downcase it (under w32-downcase-file-names).
8 2012-12-01 Chong Yidong <cyd@gnu.org>
10 * fileio.c (Vauto_save_list_file_name): Doc fix.
12 2012-11-30 Fabrice Popineau <fabrice.popineau@gmail.com>
14 * w32fns.c: Remove prototype of atof.
15 (syspage_mask): Declared DWORD_PTR, for compatibility with 64-bit
17 (file_dialog_callback): Declared UINT_PTR.
19 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
22 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
23 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
26 2012-11-27 Glenn Morris <rgm@gnu.org>
28 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
30 2012-11-26 Eli Zaretskii <eliz@gnu.org>
32 * fontset.c (Finternal_char_font): Return nil on non-GUI frames.
35 2012-11-24 Paul Eggert <eggert@cs.ucla.edu>
37 Revert recent change for Bug#8855.
38 As reported by Harald Hanche-Olsen in
39 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00445.html>
40 the change introduces a further bug, of creating lots of zombie
41 processes in some cases. Further work is needed to come up with a
42 better fix for Bug#8855.
44 2012-11-24 Eli Zaretskii <eliz@gnu.org>
46 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
47 highlighting on the frame was cleared. Prevents assertion
48 violations when repeatedly clicking on the "Top" link of the
49 "bread-crumbs" in Info buffers.
51 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>
52 Eli Zaretskii <eliz@gnu.org>
54 Fix a race condition with glib (Bug#8855).
55 The symptom is a diagnostic "GLib-WARNING **: In call to
56 g_spawn_sync(), exit status of a child process was requested but
57 SIGCHLD action was set to SIG_IGN and ECHILD was received by
58 waitpid(), so exit status can't be returned." The diagnostic
59 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
60 The real bug is a race condition between Emacs and glib: Emacs
61 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
62 so that glib can't find it. Work around the bug by invoking
63 waitpid only on subprocesses that Emacs itself creates.
65 This is a backport from the trunk, consisting of:
67 * w32proc.c (create_child): Don't clip the PID of the child
68 process to fit into an Emacs integer, as this is no longer a
70 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
71 reaping only the process specified by PID argument, if that is
72 positive. Use PID instead of dead_child to know which process to
73 reap. Wait for the child to die only if WNOHANG is not in
75 (sys_select): Don't set dead_child.
77 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
78 as it is no longer needed.
80 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
82 (create_process, record_child_status_change): Don't use special
83 value -1 in pid field, as the caller now must know the pid rather
84 than having the callee infer it. The inference was sometimes
85 incorrect anyway, due to another race.
86 (create_process): Set new 'alive' member if child is created.
87 (process_status_retrieved): New function.
88 (record_child_status_change): Use it.
89 Accept negative 1st argument, which means to wait for the
90 processes that Emacs already knows about. Move special-case code
91 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
92 processes that have already been waited for, by testing and
93 clearing new 'alive' member. Remove the setting of
94 record_at_most_one_child for the !WNOHANG case.
95 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
96 now does this internally.
97 (handle_child_signal): Let record_child_status_change do all
98 the work, since we do not want to reap all exited child processes,
99 only the child processes that Emacs itself created.
100 * process.h (Lisp_Process): New boolean member 'alive'.
102 2012-11-23 Eli Zaretskii <eliz@gnu.org>
104 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
105 between bpos_covered and bpos_max. This fixes cursor display when
106 several display strings follow each other.
108 * .gdbinit (pgx): If the glyph's object is a string, display the
109 pointer to string data, rather than the value of the string object
110 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
112 2012-11-21 Eli Zaretskii <eliz@gnu.org>
114 * indent.c (Fvertical_motion): If the starting position is covered
115 by a display string, return to one position before that, to avoid
116 overshooting it inside move_it_to. (Bug#12930)
118 2012-11-20 Daniel Colascione <dancol@dancol.org>
120 * w32fns.c (Fx_file_dialog):
121 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
122 cygwin_convert_file_name*.
124 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
125 Rename cygwin_convert_path* to cygwin_convert_file_name*.
127 2012-11-20 Ken Brown <kbrown@cornell.edu>
129 * emacs.c (main): Set the G_SLICE environment variable for all
130 Cygwin builds, not just GTK builds. See
131 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
133 2012-11-19 Eli Zaretskii <eliz@gnu.org>
135 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Don't mix declaration of
136 w32_note_current_window with code. (Backport from trunk.)
138 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
139 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
140 Define for the MSVC compiler.
142 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing
145 2012-11-18 Eli Zaretskii <eliz@gnu.org>
147 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
148 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
149 dostounix_filename. Prevents crashes down the road, because
150 dostounix_filename assumes it gets a unibyte string. Reported by
151 Michel de Ruiter <michel@sentient.nl>, see
152 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html
154 2012-11-17 Eli Zaretskii <eliz@gnu.org>
156 * w32select.c: Include w32common.h before w32term.h, so that
157 windows.h gets included before w32term.h uses some of its
160 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]: New
162 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]: New
164 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
166 2012-11-17 Jan Djärv <jan.h.d@swipnet.se>
168 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
169 (ns_select): Return at once if events are held (Bug#12834).
171 2012-11-16 enami tsugutomo <tsugutomo.enami@jp.sony.com>
173 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
174 Needed following 2012-10-20 change. (Bug#12902)
176 2012-11-16 Glenn Morris <rgm@gnu.org>
178 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
180 2012-11-15 Stefan Monnier <monnier@iro.umontreal.ca>
182 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
184 2012-11-14 Eli Zaretskii <eliz@gnu.org>
186 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
187 use the same value of thread handle.
188 (start_timer_thread): If the timer thread exited (due to error),
189 clean up by closing the two handles it used. Duplicate the caller
190 thread's handle here, so it gets duplicated only once, when
191 launching the timer thread. Set priority of the timer thread, not
193 (getitimer): Don't duplicate the caller thread's handle here.
196 2012-11-13 Jan Djärv <jan.h.d@swipnet.se>
198 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
201 2012-11-12 Eli Zaretskii <eliz@gnu.org>
203 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
204 passed to pint2str and pint2hrstr to be at most the size of the
205 frame's decode_mode_spec_buffer. This avoids crashes with very
206 large values of FIELD_WIDTH argument to decode_mode_spec.
209 2012-11-07 Martin Rudalics <rudalics@gmx.at>
211 * window.c (Fsplit_window_internal): Set combination limit of
212 new parent window to t iff Vwindow_combination_limit is t;
213 fixing a regression introduced with the change from 2012-09-22.
214 (Fwindow_combination_limit, Fset_window_combination_limit):
217 2012-11-06 Eli Zaretskii <eliz@gnu.org>
219 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
220 amount when the scroll margins are too large. When scrolling
221 backwards in the buffer, give up if cannot reach point or the
222 scroll margin within a reasonable number of screen lines.
223 Fixes point position in window under scroll-up/down-aggressively when
224 point is positioned many lines beyond the window top/bottom.
227 2012-11-05 Eli Zaretskii <eliz@gnu.org>
229 * ralloc.c (relinquish): If real_morecore fails to return memory
230 to the system, don't crash; instead, leave the last heap
231 unchanged and return. (Bug#12774)
233 2012-11-03 Eli Zaretskii <eliz@gnu.org>
235 * lisp.mk: Adjust comments to the fact that term/internal is now
236 loaded from loadup.el.
238 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
239 (msdos_fatal_signal): New function.
240 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
243 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
244 for GCC versions before 4.
245 (emacs_raise): Define to call msdos_fatal_signal.
247 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
248 iterator when starting in the middle of a display or overlay
251 2012-11-03 Jan Djärv <jan.h.d@swipnet.se>
253 * widget.c (resize_cb): New function.
254 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
255 (EmacsFrameResize): Check if all is up to date before changing frame
258 2012-11-01 Eli Zaretskii <eliz@gnu.org>
260 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
262 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
264 Fix crash when using Emacs as commit editor for git (Bug#12697).
265 * callproc.c (setpgrp): Remove macro, as we now use setpgid
266 and it is configured in conf_post.h.
267 (Fcall_process): Don't invoke both setsid and setpgid; the former
268 is enough, if it exists.
269 * callproc.c (Fcall_process, child_setup):
270 * process.c (create_process): Use setpgid.
271 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
273 * dispnew.c (init_display): Initialize the foreground group
274 if we are running a tty display.
275 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
276 * lisp.h (init_foreground_group): New decl.
277 * sysdep.c (inherited_pgroup): New static var.
278 (init_foreground_group, tcsetpgrp_without_stopping)
279 (narrow_foreground_group, widen_foreground_group): New functions.
280 (init_sys_modes): Narrow foreground group.
281 (reset_sys_modes): Widen foreground group.
283 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
285 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
287 2012-10-31 Martin Rudalics <rudalics@gmx.at>
289 * minibuf.c (read_minibuf): Restore current buffer since
290 choose_minibuf_frame calling Fset_frame_selected_window may
291 change it (Bug#12766).
293 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
295 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
297 2012-10-30 Kenichi Handa <handa@gnu.org>
299 * font.c (Ffont_at): If WINDOW is specified and it is not
300 displaying the current buffer, signal an error.
302 2012-10-29 Daniel Colascione <dancol@dancol.org>
304 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
305 In preparation for fixing bug#12739, move these functions from
308 * coding.h, coding.c: ... to here, and compile them only when
309 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
310 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
312 2012-10-28 Eli Zaretskii <eliz@gnu.org>
314 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
315 (timer_loop, getitimer, setitimer): Use it instead of
316 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
318 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
321 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
323 * nsterm.m (NO_APPDEFINED_DATA): New define.
324 (last_appdefined_event_data): New variable
325 (last_appdefined_event): Remove.
326 (ns_select): Initialize t from last_appdefined_event_data instead
327 of [last_appdefined_event data1].
328 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
329 remove last_appdefined_event (Bug#12698).
331 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
333 * frame.c (x_set_font): Catch internal error.
335 2012-10-27 Eli Zaretskii <eliz@gnu.org>
337 Avoid overflow in w32 implementation of interval timers.
338 When possible, for ITIMER_PROF count only times the main thread
340 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
341 'volatile ULONGLONG' types. All the other data which was
342 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
343 (GetThreadTimes_Proc): New typedef.
344 (w32_get_timer_time): New function, returns a suitable time value
346 (timer_loop): Enter critical section when accessing ULONGLONG
347 values of the itimer_data struct, as these accesses are no longer
348 atomic. Call 'w32_get_timer_time' instead of 'clock'.
349 Remove unused variable.
350 (init_timers): Initialize s_pfn_Get_Thread_Times.
351 (start_timer_thread): Don't assign itimer->caller_thread here.
352 (getitimer): Assign itimer->caller_thread here.
353 (setitimer): Always call getitimer to get the value of ticks_now.
354 (sys_spawnve): Avoid compiler warning about format mismatch.
356 2012-10-26 Eli Zaretskii <eliz@gnu.org>
358 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
359 mouse movement events if the menu bar is active. This avoids
360 producing a busy "hour-glass" cursor by Windows if the mouse
361 pointer is positioned over a tooltip shown for some menu item.
363 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
365 Don't assume process IDs fit in int.
366 * emacs.c (shut_down_emacs) [!DOS_NT]:
367 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
368 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
369 Use pid_t, not int, to store process IDs, as 'int'
370 is not wide enough on a few platforms (e.g., AIX and IRIX).
372 2012-10-23 Kenichi Handa <handa@gnu.org>
374 The following change is to make face-font-rescale-alist work
375 correctly for non-ASCII fonts.
377 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
378 (font_open_for_lface): Handle Vface_font_rescale_alist.
380 2012-10-23 Chong Yidong <cyd@gnu.org>
382 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
384 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>
386 * nsfont.m (nsfont_open, ns_glyph_metrics): Force integer advancement
388 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
390 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
393 2012-10-21 Glenn Morris <rgm@gnu.org>
395 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
397 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
400 * frame.c (Fmouse_position, Fmouse_pixel_position):
401 * xdisp.c (produce_stretch_glyph):
402 Declare local vars only when they're needed.
403 This is clearer and avoids a warning on OpenBSD about unused vars.
404 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
405 This is safer, and avoids OpenBSD warnings about unused vars.
406 * keyboard.c (record_menu_key): Remove unnecessary decl.
407 (poll_timer): Define only if POLL_FOR_INPUT is defined.
408 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
409 as our definition clashes with OpenBSD's.
410 * xfaces.c (load_face_colors, check_lface_attrs)
411 (get_lface_attributes_no_remap, get_lface_attributes)
412 (lface_fully_specified_p, x_supports_face_attributes_p)
413 (tty_supports_face_attributes_p, face_fontset, realize_face)
414 (realize_x_face, realize_tty_face):
415 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
416 merely Lisp_Object *. This is more informative and avoids
417 a warning on OpenBSD about accessing beyond an object's size.
419 2012-10-20 Chong Yidong <cyd@gnu.org>
421 * lread.c (Fload): Doc fix (Bug#12592).
423 2012-10-19 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny change)
425 * font.c (Ffont_at): Fix previous change.
427 2012-10-19 Eli Zaretskii <eliz@gnu.org>
429 * puresize.h (BASE_PURESIZE): Bump the base value to 1700000.
430 See http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00593.html
433 * alloc.c (NSTATICS): Decrease to 0x800.
435 2012-10-19 Stefan Monnier <monnier@iro.umontreal.ca>
437 * fns.c (Fnreverse): Include the problem element when signalling an
440 2012-10-18 Jan Djärv <jan.h.d@swipnet.se>
442 * nsterm.m (ns_select): Check writefds before call to
443 FD_ISSET (Bug#12668).
445 2012-10-18 Daniel Colascione <dancol@dancol.org>
447 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
448 (staticpro): If we run out of staticpro slots, die with an
449 informative error instead of just calling emacs_abort.
451 2012-10-18 Martin Rudalics <rudalics@gmx.at>
453 Fix two flaws reported by Dmitry Antipov.
454 * window.c (Ftemp_output_buffer_show): Remove.

456 (syms_of_window): Remove defsubr for Stemp_output_buffer_show.
458 2012-10-17 Eli Zaretskii <eliz@gnu.org>
460 * makefile.w32-in ($(BLD)/w32.$(O)):
461 ($(BLD)/vm-limit.$(O)):
463 ($(BLD)/unexw32.$(O)):
464 ($(BLD)/fileio.$(O)):
465 ($(BLD)/dispnew.$(O)): Update dependencies.
467 * w32term.h (w32_initialize_display_info, initialize_w32_display):
470 * w32proc.c: Include ctype.h.
472 * w32.h (init_environment, check_windows_init_file)
473 (syms_of_ntproc, syms_of_ntterm, dostounix_filename)
474 (unixtodos_filename, init_winsock, srandom, random, sys_pipe)
475 (set_process_dir, sys_spawnve, register_child, sys_sleep, getwd)
476 (sys_link): Add prototypes.
478 * w32.c: Include w32select.h.
479 (sys_access, e_malloc, sys_select): Add prototypes.
480 (emacs_gnutls_pull): 'timeout' is now EMACS_TIME, not struct timeval.
482 * vm-limit.c [WINDOWSNT]: Include w32heap.h.
484 * unexw32.c: Include lisp.h and w32.h.
486 * term.c [WINDOWSNT]: Include w32term.h.
488 * process.c [WINDOWSNT]: Add prototype of sys_select.
490 * fileio.c [WINDOWSNT]: Include w32.h.
492 * dispnew.c [WINDOWSNT]: Include w32.h.
494 * cygw32.c (Fcygwin_convert_path_to_windows)
495 (Fcygwin_convert_path_from_windows): Use EQ to compare 2
496 Lisp_Object values. (Bug#12661)
498 * w32fns.c (w32_msg_pump): Use XIL instead of casting an integer
499 to Lisp_Object. (Bug#12661)
501 2012-10-17 Kenichi Handa <handa@gnu.org>
503 * xdisp.c (reseat_1): Make the information stored in it->cmp_it
506 2012-10-17 Dmitry Antipov <dmantipov@yandex.ru>

509 reset its buffer pointer to NULL (Bug#12652).
511 2012-10-17 Dmitry Antipov <dmantipov@yandex.ru>
513 Do not verify indirection counters of killed buffers (Bug#12579).

542 2012-10-15 Daniel Colascione <dancol@dancol.org>
544 * dbusbind.c: Fix cygw32 build break when compiling with dbus

546 headers define to something incompatible.
548 2012-10-14 Daniel Colascione <dancol@dancol.org>
550 * image.c (init_tiff_functions, init_imagemagick_functions)
551 (init_svg_functions): Fix cygw32 build break by using these
552 functions only when WINDOWSNT _and_ HAVE_NTGUI.

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

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

735 Clean out old termopts cruft.
736 * termopts.h (flow_control, meta_key): Remove unused decls.
737 * dispnew.c, indent.c, nsterm.m, term.c, xsettings.c, xsmfns.c:
738 Don't include termopts.h.
740 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>

748 2012-10-09 Jan Djärv <jan.h.d@swipnet.se>

755 2012-10-09 Eli Zaretskii <eliz@gnu.org>
757 * w32fns.c (w32_last_error): Change the return value to DWORD, to
758 match what GetLastError returns. Explain why the function is
761 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
762 'is_tooltip_frame', to avoid confusion with its global namesake.
764 2012-10-08 Daniel Colascione <dancol@dancol.org>
766 * xdisp.c (start_hourglass): Call w32_note_current_window when
767 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
768 build that caused Emacs to display the hourglass cursor forever.
770 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
771 which is broken under remote desktop, calculate the number of
772 colors available for a display based on the display's number of
773 planes and number of bits per pixel per plane. (bug#10397).
775 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
777 * nsfont.m (Vfonts_in_cache): New variable.
778 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
779 are used. Add cached fonts to Vfonts_in_cache.
780 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
782 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
784 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
786 (FONT_H): Define after FRAME_H.
787 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
790 * w32term.c: Remove leftover declaration of keyboard_codepage.
792 2012-10-08 Eli Zaretskii <eliz@gnu.org>
794 * makefile.w32-in (FONT_H): Add $(FRAME_H).
795 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
796 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
797 (GLOBAL_SOURCES): Add cygw32.c.
798 ($(BLD)/unexw32.$(O)):
800 ($(BLD)/w32console.$(O)):
801 ($(BLD)/w32fns.$(O)):
802 ($(BLD)/w32heap.$(O)):
803 ($(BLD)/w32menu.$(O)):

806 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
808 (x_to_w32_color): Don't modify the argument, modify a copy instead.
810 2012-10-08 Daniel Colascione <dancol@dancol.org>
812 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
813 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
814 accidental message numbering hole. Change other messages to
817 * w32select.h (HAVE_W32SELECT): Remove.
819 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
820 w32common.h instead of w32heap.h.
822 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
823 (get_allocation_unit, get_processor_type, get_w32_major_version)

830 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
831 (w32_minor_version, w32_build_number, w32_subtype):
832 Remove duplicate definitions.
834 * w32fns.c: Include w32common.h; include w32heap.h only in
837 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
838 Use `report_file_error' instead of `error' in order to better
839 inform users of what went wrong. Increase NTGUI_UNICODE file
840 dialog box file name length to 32k, the maximum allowed by the NT
843 * w32common.h: New file.
844 (ROUND_UP, ROUND_DOWN, get_page_size)
845 (get_allocation_unit, get_processor_type, get_w32_major_version)
846 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
847 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
848 (OS_NT, os_subtype, cache_system_info): Move here.
850 * unexw32.c, unexcw.c: Include w32common.h.
852 * emacs.c (main): Use (defined (WINDOWSNT) || defined
853 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
854 to call syms_of_w32select.
856 * cygw32.h: Remove obsolete EXFUN declarations.
858 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
860 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
861 of w32inevt.o from SOME_MACHINE_OBJECTS.
863 2012-10-08 Daniel Colascione <dancol@dancol.org>
865 * image.c: Permanent fix for JPEG compilation issue --- limit
866 jpeglib `boolean' redefinition to Cygwin builds.
868 2012-10-08 Eli Zaretskii <eliz@gnu.org>
870 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
872 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
875 2012-10-08 Daniel Colascione <dancol@dancol.org>
877 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
878 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
879 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,

881 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
882 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
883 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
884 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
885 now a supported configuration.
887 * Makefile.in: consolidate image variables into LIBIMAGE; add
888 W32_OBJ and W32_LIBS. Compile new files.
891 (_DebPrint) declare tracing facility for W32 debugging. We need
892 to unify tracing later.
894 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
895 unconditional use of W32 Unicode functions. Cygwin runs only on
896 100% Unicode operating systems.
898 * cygw32.c: New file. Define Cygwin-specific facilities.
899 (Fcygwin_convert_path_to_windows)
900 (Fcygwin_convert_path_from_windows): New user functions for
901 accessing Cygwin path-munging routines.
903 * cygw32.h: New file.
904 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
905 UTF-16LE strings temporarily inside non-Lisp-visible string
908 (w32_strerror): Just what it says on the tin.
910 * emacs.c: Make the NS fork-then-exec code for daemon-launching
911 also run for Cygwin; both systems have the same problem with using
912 GUI facilities in a forked child. Also call syms_of_cygw32,
913 syms_of_w32select in correct places.
915 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
916 needs fork-then-exec for daemon launching.
918 * font.h: Include frame.h.
920 * image.c: Use the image library cache machinery only when we're
921 compiling for native WINDOWSNT; Cygwin can use shared libraries
922 like any other Unixlike system.
924 * keyboard.c: Clarify a comment regarding the input loop.
926 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
927 functions directly instead of trying to detect at runtime that our
928 host operating system supports them. We make this change for two
929 reasons: Cygwin lacks support for the multibyte character
930 conversion functions used by the legacy menu code, and Cygwin
931 never needs to rely on non-Unicode APIs.
933 * unexw32.c (hinst): Declare extern.
935 * w32.c: Change header order;
936 (w32_strerror): Move to w32fns.c because we need it for
937 non-WINDOWSNT builds.
939 * w32.h: Add #error macro to make sure we don't include w32.h for
940 Cygwin builds. Remove w32select declarations.
942 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
943 w32fns.c. w32console.c is WINDOWSNT-only.
945 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
946 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
948 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
949 (w32_major_version, w32_minor_version, w32_build_number)
950 (os_subtype, sound_type): Define here
951 (w32_defined_color): Make color parameter const for consistency
952 with other _defined_color functions.
953 (w32_createwindow): Unconditionally call w32_init_class instead of
954 doing so only when hprevinst is non-NULL. Plumbing hprevinst
955 through the code is complex and unnecessary because class
956 registration is practically free.
957 (w32_name_of_message): New EMACSDEBUG-only function.
958 (Fset_message_beep): Move here
959 (Fx_open_connection): Require that the display name for Windows be
960 "w32" for consistency, emacsclient disambiguation, and maybe, one
961 day, multi-window-system support.
962 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
963 Cygwin files for W32 GUI facilities, since these clearly don't
966 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
967 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
968 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
969 (w32_last_error): Remove.
971 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
973 * w32heap.c (syspage_mask): Declare here.
974 (cache_system_info): Remove.
976 * w32inevt.c (faked_key): Define globally, not statically.
977 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
978 (w32_console_toggle_lock_key): Move to w32fns.c.
980 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
982 * w32proc.c (_DebPrint): Move to w32fns.c.
983 * w32select.c: Include string.h, stdio.h for Cygwin.
984 * w32select.h: New File.
986 * w32term.c: Include io.h for non-CYGWIN builds; needed for
988 (w32_message_fd): New variable. Under Cygwin, holds the file
989 descriptor the system used to tell us about pending thread
992 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
993 that prevented compilation under non-WINDOWSNT systems.
995 (w32_initialize): Open /dev/windows and assign it to
996 w32_message_fd. Provide w32 feature.
998 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
999 (WM_EMACS_INPUT_READY): add.
1000 (prepend_msg, w32_message_fd): Declare globally.
1003 (keyboard_handle): Use only when WINDOWSNT.
1004 (notify_msg_ready): New function. Posts a message to the main
1005 thread's message queue under CYGWIN, which wakes up the main
1006 thread from select(2) by making the /dev/windows file descriptor
1007 ready. Under WINDOWSNT, it sets an event the same way the old
1010 (post, prepend_msg): Actually call notify_msg_ready instead of
1011 setting the input event directly.
1013 2012-10-07 Eli Zaretskii <eliz@gnu.org>
1015 * ralloc.c (relinquish): If a heap is ready to be relinquished,
1016 but it still has blocs in it, don't return it to the system,
1017 instead of aborting. (Bug#12402)
1019 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>

1052 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
1054 Improve sys_siglist detection.
1055 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
1056 defined as a macro, as is done in Solaris.
1057 (sys_siglist_entries): New macro.
1058 (save_strsignal): Use it.
1059 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
1060 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
1062 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
1064 * nsfns.m (Fx_create_frame): Call x_default_parameter with
1065 fullscreen/Fullscreen.
1067 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
1068 tobar_height is new.
1070 * nsterm.m (x_make_frame_visible): Check for fullscreen.
1071 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
1072 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.

1085 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
1087 2012-10-05 Eli Zaretskii <eliz@gnu.org>
1089 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
1091 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
1092 that time stamps of directories could also be changed.
1093 Don't request the too broad GENERIC_WRITE, only the more restrictive
1094 FILE_WRITE_ATTRIBUTES access rights.
1096 * fileio.c (Fset_file_times): Special-case ignoring errors for
1097 directories only on MSDOS, not on MS-Windows.
1099 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
1101 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
1103 2012-10-04 Eli Zaretskii <eliz@gnu.org>

1106 see whether CreateFile failed.
1108 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
1110 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
1111 to avoid similar races.
1112 * keyboard.c (pending_signals): Now bool, not int.
1114 Port timers to OpenBSD, plus check for timer failures.
1115 OpenBSD problem reported by Han Boetes.
1116 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
1118 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
1119 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
1120 like OpenBSD, which has timer_settime but does not declare it.
1121 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
1122 whether to use itimerspec-related primitives. All uses of
1123 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
1125 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
1127 * profiler.c (handle_profiler_signal): Fix a malloc race
1128 that caused Emacs to hang on Fedora 17 when profiling Lisp.
1130 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
1132 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
1134 2012-10-02 Eli Zaretskii <eliz@gnu.org>
1136 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
1137 consistent with the change in return value of 'safe_strsignal'.
1139 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
1141 Prefer plain 'static' to 'static inline' (Bug#12541).
1142 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
1143 (bidi_set_sor_type, bidi_push_embedding_level)
1144 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)

1149 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
1150 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
1151 Now 'static', not 'static inline'.
1153 Count overruns when profiling; change units to ns.
1154 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
1155 Give extra weight to samples after overruns, to attempt to count
1156 the time more accurately.
1157 (setup_cpu_timer): Change sampling interval units from ms to ns, since
1158 the underlying primitives nominally do ns.
1159 (Fprofiler_cpu_start): Document the change. Mention that
1160 the sampling intervals are only approximate.
1162 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
1164 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
1166 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
1167 case for the special 0 coding-system.
1169 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
1170 (Fmake_overlay): Remove redundant tests.
1171 (fix_start_end_in_overlays): Remove redundant recentering.
1173 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
1175 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
1176 Update dependencies.
1178 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
1180 Fix a malloc race condition involving strsignal.
1181 A signal can arrive in the middle of a malloc, and Emacs's signal
1182 handler can invoke strsignal, which can invoke malloc, which is
1183 not portable. This race condition bug makes Emacs hang on GNU/Linux.
1184 Fix it by altering the signal handler so that it does not invoke
1186 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
1187 * process.c (status_message): Use const pointer, in case strsignal
1188 is #defined to safe_strsignal.
1189 * sysdep.c (sys_siglist, init_signals): Always define and
1190 initialize a substitute sys_siglist if the system does not define
1191 one, even if HAVE_STRSIGNAL.
1192 (safe_strsignal): Rename from strsignal. Always define,
1193 using sys_siglist. Return a const pointer.
1194 * syssignal.h (safe_strsignal): New decl.
1195 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
1197 2012-10-01 Eli Zaretskii <eliz@gnu.org>
1199 * w32proc.c (timer_loop): Fix code that waits for timer
1200 expiration, to avoid high CPU usage.
1202 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
1204 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
1205 (sweep_weak_table): Remove redundant prototypes.
1207 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
1209 * emacs.c: Move the inclusion of TERM_HEADER after including
1210 windows.h on WINDOWSNT. This avoids compilation problems with
1213 2012-10-01 Eli Zaretskii <eliz@gnu.org>
1215 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
1216 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
1217 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
1218 as the previous version used 'void *'.
1220 * ralloc.c (ROUNDUP): Fix last change.
1221 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
1224 * w32proc.c <disable_itimers>: New static flag.
1225 (init_timers): Initialize it to zero, after creating the critical
1226 sections used by the timer threads.
1227 (term_timers): Set to 1 before deleting the critical sections.
1228 (getitimer, setitimer): If disable_itimers is non-zero, return an
1229 error indication without doing anything. Reported by Fabrice
1230 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
1231 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
1233 [!HAVE_SETITIMER]: Behave as the previous version that didn't
1236 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
1237 term_ntproc after all the other bookkeeping, to get timers working
1238 as long as possible.
1240 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
1242 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
1243 Suggested by Juri Linkov in
1244 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
1246 Prefer plain 'static' to 'static inline' (Bug#12541).
1247 With static functions, modern compilers inline pretty well by
1248 themselves; advice from programmers often hurts as much as it helps.
1249 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
1250 this change shrinks the text size of the Emacs executable by 1.1%
1251 without affecting CPU significantly in my benchmark.
1252 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)

1334 Revert the FOLLOW-SYMLINKS change for file-attributes.
1335 Doing it right would require several changes to Tramp, and there's
1336 not enough time to get that tested before the freeze today.
1337 * dired.c (directory_files_internal, Ffile_attributes):
1340 * frame.c (x_report_frame_params): Port better to wider ints.
1341 Do not assume that EMACS_UINT is the same width as uprintmax_t,
1342 or that pointers can be printed in 15 decimal digits.
1343 Avoid GCC warnings if EMACS_UINT is wider than a pointer.

1379 * vm-limit.c (lim_data): Now size_t.
1380 (check_memory_limits): Adjust prototypes of real_morecore and
1381 __morecore to receive argument of type ptrdiff_t. Use size_t for

1455 Remove, no longer used.
1456 (w32_note_current_window, show_hourglass, hide_hourglass):
1457 New functions, in support of hourglass cursor display similar to other
1459 (syms_of_w32fns): Don't initialize hourglass_timer.
1461 * xdisp.c (start_hourglass, cancel_hourglass): Now used on
1463 (start_hourglass) [WINDOWSNT]: Call w32_note_current_window.

1508 2012-09-30 Juanma Barranquero <lekktu@gmail.com>
1510 * makefile.w32-in ($(BLD)/profiler.$(O)): Update dependencies.
1512 2012-09-30 Chong Yidong <cyd@gnu.org>
1514 * fns.c (Frandom): Doc fix.

1521 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
1523 * syssignal.h (PROFILER_CPU_SUPPORT): Don't define if PROFILING.
1524 Suggested by Eli Zaretskii in
1525 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00811.html>.
1527 2012-09-30 Eli Zaretskii <eliz@gnu.org>
1529 * profiler.c (Fprofiler_cpu_stop): Use timer_settime only if
1530 HAVE_TIMER_SETTIME is defined.
1532 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
1534 Profiler improvements: more-accurate timers, overflow checks.
1535 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
1536 signal.h, setjmp.h. Include systime.h instead.
1537 (saturated_add): New function.
1538 (record_backtrace, current_sample_interval): Use EMACS_INT, not size_t.
1539 (record_backtrace, handle_profiler_signal): Saturate on fixnum overflow.
1540 (profiler_timer, profiler_timer_ok) [HAVE_TIMER_SETTIME]:
1542 (enum profiler_cpu_running): New enum.
1543 (profiler_cpu_running): Now of that enum type, not bool.
1544 All uses changed to store the new value.
1545 (handle_profiler_signal): Rename from sigprof_handler_1,
1546 for consistency with other handlers. Do not check whether
1547 cpu_log is a hash-table if garbage collecting, since it
1548 doesn't matter in that case.
1549 (deliver_profiler_signal): Rename from sigprof_handler,
1550 for consistency with other handlers.
1551 (setup_cpu_timer): New function, with much of what used to be in
1552 Fprofiler_cpu_start. Check for out-of-range argument.
1553 Prefer timer_settime if available, and prefer
1554 thread cputime clocks, then process cputime clocks, then
1555 monotonic clocks, to the old realtime clock. Use make_timeval
1556 to round more-correctly when falling back to setitimer.
1557 (Fprofiler_cpu_start): Use it.
1558 (Fprofiler_cpu_stop): Prefer timer_settime if available.
1559 Don't assume that passing NULL as the 2nd argument of setitimer
1560 is the same as passing a pointer to all-zero storage.
1561 Ignore SIGPROF afterwards.
1562 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
1563 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
1564 non-fatal signal handlers. Ignore SIGPROF on startup.
1565 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
1566 in profiler.c, since sysdep.c now uses it.
1568 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.
1569 Suggested by Eli Zaretskii in

1623 * charset.c, charset.h (maybe_unify_char): Now static.
1624 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
1625 Since this stuff is now private to charset.c, there's no need for
1626 a public macro and no need to inline by hand.

1659 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>
1661 Prefer POSIX timers if available.
1662 They avoid a race if the timer is too close to the current time.

1692 2012-09-25 Eli Zaretskii <eliz@gnu.org>
1694 * w32proc.c (sys_signal): Handle all signals defined by the
1695 MS-Windows runtime, not just SIGCHLD. Actually install the signal
1696 handlers for signals supported by Windows. Don't override
1697 term_ntproc as the handler for SIGABRT.
1698 (sigaction): Rewrite to call sys_signal instead of duplicating its
1700 (sys_kill): Improve commentary.
1702 * w32.c (term_ntproc): Accept (and ignore) one argument, for
1703 consistency with a signature of a signal handler. All callers
1705 (init_ntproc): Accept an argument DUMPING. If dumping, don't
1706 install term_ntproc as a signal handler for SIGABRT, as that
1707 should be done by the dumped Emacs.
1709 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
1711 * w32select.c (term_w32select): Protect against repeated
1712 invocation by setting clipboard_owner to NULL after calling
1715 * emacs.c (shut_down_emacs, main): Adapt the calls to init_ntproc
1716 and term_ntproc to their modified signatures.

1778 (interruptible_wait_for_termination):
1779 Move these decls from lisp.h to syswait.h, since they use pid_t.
1780 Needed on FreeBSD; see Herbert J. Skuhra in
1781 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.

1830 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
1831 fatal_error_backtrace.
1833 * w32proc.c (sys_kill): Undo last change: don't do anything when
1834 invoked to deliver SIGABRT to our own process. This is now
1835 handled by emacs_raise.
1837 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
1839 * w32term.c (w32_read_socket): Remove leftover reference to
1840 interrupt_input_pending.
1842 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>

1849 * emacs.c (terminate_due_to_signal): Reset signal handler here.
1850 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
1851 wanted even on POSIXish hosts, and it doesn't work on Windows.
1853 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
1855 * xterm.c (x_term_init): Call fixup_locale before and after calling
1856 gtk_init (Bug#12392).
1858 2012-09-23 Chong Yidong <cyd@gnu.org>
1860 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
1861 Vdynamic_library_alist.

1874 (init_tiff_functions, init_gif_functions, init_svg_functions):
1875 Arglist and w32_delayed_load calling convention changed.
1876 (gs_type): Remove init_gs_functions; there is no such function.
1877 (valid_image_p, make_image): Fix caller to lookup_image_type.
1879 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
1881 Simplify and avoid signal-handling races (Bug#12471).
1883 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
1884 Avoid recursive loop if there's a fatal error in the function itself.
1885 * atimer.c (pending_atimers):
1886 * blockinput.h: Don't include "atimer.h"; no longer needed.
1887 (interrupt_input_pending): Remove. All uses removed.
1888 pending_signals now counts both atimers and ordinary interrupts.
1889 This is less racy than having three separate pending-signal flags.
1890 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
1892 Rename from their upper-case counterparts BLOCK_INPUT,
1893 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
1894 INPUT_BLOCKED_P, and turn into functions. All uses changed.
1895 This makes it easier to access volatile variables more accurately.
1896 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
1897 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
1898 that's more reliable if the code is buggy and sets
1899 interrupt_input_blocked to a negative value. All uses changed.
1900 * atimer.c (deliver_alarm_signal):
1901 Remove. No need to deliver this to the parent; any thread can
1902 handle this signal now. All uses replaced by underlying handler.
1903 * atimer.c (turn_on_atimers):
1904 * dispnew.c (handle_window_change_signal):
1905 * emacs.c (handle_danger_signal):
1906 * keyboard.c (kbd_buffer_get_event):
1907 Don't reestablish signal handler; not needed with sigaction.
1908 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
1910 Rework to avoid unnecessary accesses to volatile variables.
1911 (UNBLOCK_INPUT_TO): Now a function.
1912 (totally_unblock_input, unblock_input): New decls.
1913 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
1914 (init_data): Remove. Necessary stuff now done in init_signal.
1915 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
1916 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
1917 (fatal_error_code): Remove; no longer needed.
1918 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
1919 it doesn't always backtrace. All uses changed. No need to reset
1920 signal to default, since sigaction and/or die does that for us now.
1921 Use emacs_raise (FOO), not kill (getpid (), FOO).
1922 (main): Check more-accurately whether we're dumping.
1923 Move fatal-error setup to sysdep.c
1924 * floatfns.c: Do not include "syssignal.h"; no longer needed.
1925 * gtkutil.c (xg_get_file_name, xg_get_font):
1926 Remove no-longer-needed signal-mask manipulation.
1927 * keyboard.c, process.c (POLL_FOR_INPUT):
1928 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
1929 * keyboard.c (read_avail_input): Remove.
1930 All uses replaced by gobble_input.
1931 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
1932 (kbd_buffer_store_event_hold, gobble_input):
1933 (record_asynch_buffer_change) [USABLE_SIGIO]:
1934 (store_user_signal_events):
1935 No need to mess with signal mask.
1936 (gobble_input): If blocking input and there are terminals, simply
1937 set pending_signals to 1 and return. All hooks changed to not
1938 worry about whether input is blocked.
1939 (process_pending_signals): Clear pending_signals before processing
1940 them, in case a signal comes in while we're processing.
1941 By convention callers now test pending_signals before calling us.
1942 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
1943 New functions, to support changes to blockinput.h.
1944 (handle_input_available_signal): Now extern.
1945 (reinvoke_input_signal): Remove. All uses replaced by
1947 (quit_count): Now volatile, since a signal handler uses it.
1948 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
1949 All callers changed. Block SIGINT only if not already blocked.
1950 Clear sigmask reliably, even if Fsignal returns, which it can.
1951 Omit unnecessary accesses to volatile var.
1952 (quit_throw_to_read_char): No need to restore sigmask.
1953 * keyboard.c (gobble_input, handle_user_signal):
1954 * process.c (wait_reading_process_output):
1955 Call signal-handling code rather than killing ourselves.
1956 * lisp.h: Include <float.h>, for...
1957 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
1958 (pending_signals): Now volatile.
1959 (syms_of_data): Now const if IEEE floating point.
1960 (handle_input_available_signal) [USABLE_SIGIO]:
1961 (terminate_due_to_signal, record_child_status_change): New decls.
1962 * process.c (create_process): Avoid disaster if memory is exhausted
1963 while we're processing a vfork, by tightening the critical section
1965 (send_process_frame, process_sent_to, handle_pipe_signal)
1966 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
1968 (send_process): No need for setjmp/longjmp any more, since the
1969 SIGPIPE stuff is now gone. Instead, report an error if errno
1971 (record_child_status_change): Now extern. PID and W are now args.
1972 Return void, not bool. All callers changed.
1973 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
1974 Remove. All uses removed. This bug should be fixed now in a
1976 (wait_for_termination_1): Use waitpid rather than sigsuspend,
1977 and record the child status change directly. This avoids the
1978 need to futz with the signal mask.
1979 (process_fatal_action): Move here from emacs.c.
1980 (emacs_sigaction_flags): New function, containing
1981 much of what used to be in emacs_sigaction_init.
1982 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
1983 caught by emacs, to make races less likely.
1984 (deliver_process_signal): Rename from handle_on_main_thread.
1986 (BACKTRACE_LIMIT_MAX): Now at top level.
1987 (thread_backtrace_buffer, threadback_backtrace_pointers):
1989 (deliver_thread_signal, deliver_fatal_thread_signal):
1990 New functions, for more-accurate delivery of thread-specific signals.
1991 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
1992 (deliver_arith_signal): Handle in this thread, not
1993 in the main thread, since it's triggered by this thread.
1994 (maybe_fatal_sig): New function.
1995 (init_signals): New arg DUMPING so that we can be more accurate
1996 about whether we're dumping. Caller changed.
1997 Treat thread-specific signals differently from process-general signals.
1998 Block all signals while handling fatal error; that's safer.
1999 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
2001 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
2002 Ignore SIGPIPE unless batch.
2003 (emacs_backtrace): Output backtrace for the appropriate thread,
2004 which is not necessarily the main thread.
2005 * syssignal.h: Include <stdbool.h>.
2006 (emacs_raise): New macro.
2007 * xterm.c (x_connection_signal): Remove; no longer needed
2008 now that we use sigaction.
2009 (x_connection_closed): No need to mess with sigmask now.
2010 (x_initialize): No need to reset SIGPIPE handler here, since
2011 init_signals does this for us now.
2013 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
2015 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
2016 background rect may be larger (Bug#12245).
2018 2012-09-23 Chong Yidong <cyd@gnu.org>
2020 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
2022 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
2024 * .gdbinit: Just stop at fatal_error_backtrace.
2025 See Stefan Monnier's request in
2026 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
2027 Remove no-longer-used query of system type.
2029 2012-09-22 Chong Yidong <cyd@gnu.org>
2031 * search.c (Freplace_match): Doc fix (Bug#12325).
2033 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
2035 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
2036 (Fline_end_position): Doc fix.
2038 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
2040 2012-09-22 Chong Yidong <cyd@gnu.org>
2042 * dispextern.h (struct image_type): Add new slot, storing a type
2043 initialization function.
2045 * image.c (define_image_type): Call the image initializer function
2046 if it is defined. Arguments and return value changed.
2047 (valid_image_p, make_image): Callers changed.
2048 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
2049 (gif_type, imagemagick_type, svg_type, gs_type):
2050 Add initialization functions.
2051 (Finit_image_library): Call lookup_image_type.
2052 (CHECK_LIB_AVAILABLE): Macro deleted.
2053 (lookup_image_type): Call define_image_type here, rather than via
2054 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
2055 (syms_of_image): Move define_image_type calls for xbm_type and
2056 pbm_type to lookup_image_type.
2058 2012-09-22 Eli Zaretskii <eliz@gnu.org>
2060 * keyboard.c (timer_check_2): Move calculation of 'timers' and
2061 'idle_timers' from here ...
2062 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
2063 lists, to avoid infloops when the timer does something stupid,
2064 like reinvoke itself with the same or smaller time-out.
2067 2012-09-22 Martin Rudalics <rudalics@gmx.at>
2069 * window.c (Fsplit_window_internal): Handle only Qt value of
2070 Vwindow_combination_limit separately.
2071 (Qtemp_buffer_resize): New symbol.
2072 (Vwindow_combination_limit): New default value.
2075 2012-09-22 Eli Zaretskii <eliz@gnu.org>
2077 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
2078 the new overlay string. (Bug#10159)
2080 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
2082 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
2083 or that fprintf is async-signal-safe. POSIX doesn't require
2086 2012-09-22 Chong Yidong <cyd@gnu.org>
2088 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
2091 2012-09-22 Kenichi Handa <handa@gnu.org>
2093 * composite.c (composition_reseat_it): Handle the case that a
2094 grapheme cluster is not covered by a single font (Bug#12352).
2096 2012-09-21 Chong Yidong <cyd@gnu.org>
2098 * image.c (define_image_type): Avoid adding duplicate types to
2099 image_types (Bug#12463). Suggested by Jörg Walter.
2101 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2103 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
2104 (print_load_command_name): Add case LC_DATA_IN_CODE.
2105 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
2107 2012-09-21 Glenn Morris <rgm@gnu.org>
2109 * eval.c (Frun_hook_with_args_until_success)
2110 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
2112 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
2114 * fileio.c (Ffile_selinux_context): Only call freecon when
2115 lgetfilecon succeeded.
2116 (Fset_file_selinux_context): Likewise. (Bug#12444)
2118 2012-09-21 Eli Zaretskii <eliz@gnu.org>
2120 * xdisp.c (try_window_reusing_current_matrix): Under bidi
2121 reordering, locate the cursor by calling set_cursor_from_row; if
2122 that fails, clear the desired glyph matrix before returning a
2123 failure indication to the caller. Fixes leaving garbled display
2124 when fast scrolling with a down-key. (Bug#12403)
2125 (compute_stop_pos_backwards): Fix a typo that caused crashes while
2126 scrolling through multibyte text.
2128 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
2130 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
2131 calling mark_vectorlike since that's the one that marks the window.
2132 (mark_discard_killed_buffers): Mark the final cdr.
2133 * window.h (struct window): Move prev/next_buffers to the
2134 non-standard fields.
2135 * window.c (make_window): Initialize prev/next_buffers manually.
2137 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
2139 Omit unused arg EXPECTED from socket hooks.
2140 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
2141 * nsterm.m (ns_term_init):
2142 * termhooks.h (struct terminal.read_socket_hook):
2143 * w32inevt.c (w32_console_read_socket):
2144 * w32term.c (w32_read_socket):
2145 * xterm.c (XTread_socket):
2146 Omit unused arg EXPECTED. All callers changed.
2147 (store_user_signal_events): Return void, not int, since callers no
2148 longer care about the return value. All uses changed.
2150 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
2152 * w32gui.h (XParseGeometry): Do not declare.
2154 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
2156 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
2157 Ignore 'expected'. See Eli Zaretskii in
2158 <http://bugs.gnu.org/12471#8> (last line).
2160 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
2161 (XParseGeometry): Now static. Substitute extremal values for
2162 values that are out of range.
2164 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
2166 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
2168 * nsfns.m (XParseGeometry): Remove.
2169 (Fx_create_frame): Call x_set_offset to correctly interpret
2170 top_pos in geometry.
2172 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
2173 (Fx_parse_geometry): If there is a space in string, call
2174 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
2176 2012-09-17 Eli Zaretskii <eliz@gnu.org>
2178 * search.c (scan_buffer): Use character positions in calls to
2179 region_cache_forward and region_cache_backward, not byte
2180 positions. (Bug#12196)
2182 * w32term.c (w32_read_socket): Set pending_signals to 1, like
2183 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
2185 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
2186 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
2187 emacs_blocked_malloc, now deleted.
2189 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
2191 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
2192 The workaround was for improving performance on Solaris 2.4, but
2193 is getting in the way now. Emacs will still work if someone is
2194 still running Solaris 2.4 in a museum somewhere; Sun dropped
2195 support for Solaris 2.4 in 2003.
2196 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
2197 * process.c (create_process) [HAVE_WORKING_VFORK]:
2198 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
2199 since Emacs no longer uses vfork on that platform.
2201 2012-09-17 Glenn Morris <rgm@gnu.org>
2203 * emacs.c: Use COPYRIGHT.
2205 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
2207 Remove configure's --without-sync-input option (Bug#12450).
2208 When auditing signal-handling in preparation for cleaning it up,
2209 I found that SYNC_INPUT has race conditions and would be a real
2210 pain to fix. Since it's an undocumented and deprecated
2211 configure-time option, now seems like a good time to remove it.
2212 Also see <http://bugs.gnu.org/11080#16>.
2213 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
2214 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
2215 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
2216 (malloc_hysteresis):
2217 (check_depth) [XMALLOC_OVERRUN_CHECK]:
2218 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
2219 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
2220 (dont_register_blocks, bytes_used_when_reconsidered)
2221 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
2222 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
2223 [!SYSTEM_MALLOC && !SYNC_INPUT]:
2224 Remove. All uses removed.
2225 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
2226 implementation, one that depends on whether the new macro
2227 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
2229 * atimer.c (run_timers, handle_alarm_signal):
2230 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
2231 (handle_async_input, process_pending_signals)
2232 (handle_input_available_signal, init_keyboard):
2233 * nsterm.m (ns_read_socket):
2234 * process.c (wait_reading_process_output):
2235 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
2236 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
2238 * xterm.c (XTread_socket):
2240 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
2241 * eval.c (handling_signal): Remove. All uses removed.
2242 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
2243 All uses replaced with the SYNC_INPUT version.
2244 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
2246 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
2249 * font.c (Ffont_shape_gstring): Remove unused local.
2251 2012-09-16 Glenn Morris <rgm@gnu.org>
2253 * Makefile.in (clean): No longer run nextstep's clean.
2255 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
2257 (ns-app): Move here from ns.mk, and simplify.
2258 (clean): Simplify nextstep entry.
2259 * ns.mk: Remove file.
2261 2012-09-17 Kenichi Handa <handa@gnu.org>
2263 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
2264 not covert the last few charactes.
2266 2012-09-16 Kenichi Handa <handa@gnu.org>
2268 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
2269 here, but just check the validity of glyphs in the glyph-string.
2271 2012-09-16 Martin Rudalics <rudalics@gmx.at>
2273 * window.c (Fwindow_parameter, Fset_window_parameter):
2274 Accept any window as argument (Bug#12452).
2276 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
2278 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
2279 to ns_term_init to avoid memory leak.
2281 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
2282 explicit retain/release.
2283 (ns_term_init): Only allow one display. Initialize outerpool and
2286 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
2288 Port _setjmp fix to POSIXish hosts as well as Microsoft.
2289 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
2290 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
2291 the Microsoft problem in a different way, by altering ../nt/config.nt.
2293 2012-09-15 Eli Zaretskii <eliz@gnu.org>
2308 * w16select.c: Remove inclusion of setjmp.h, as it is now included
2309 by lisp.h. This completes removal of setjmp.h inclusion
2310 erroneously announced in the previous commit. (Bug#12446)
2312 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
2315 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
2316 not defined as a macro. The latter happens on MS-Windows.
2319 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
2321 Port better to POSIX hosts lacking _setjmp (Bug#12446).
2322 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
2323 Some instances of '#include <setjmp.h>' removed, if the
2324 only reason for the instance was because "lisp.h" was included.
2325 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
2326 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
2327 and _longjmp with the new symbols. Emacs already uses _setjmp if
2328 available, so this change affects only POSIXish hosts that have
2329 sigsetjmp but not _setjmp, such as some versions of Solaris and
2330 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
2331 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
2332 (png_load_body) [HAVE_PNG]:
2333 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
2334 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
2335 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
2336 since PNG requires jmp_buf. This is the only exception to the
2337 general rule that we now use sys_setjmp and sys_longjmp.
2338 This exception is OK since this code does not change the signal
2339 mask or longjmp out of a signal handler.
2341 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
2343 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
2344 Include "syssignal.h", for 'main_thread'.
2346 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
2348 Avoid out-of-range marker position (Bug#12426).
2349 * insdel.c (replace_range, replace_range_2):
2350 Adjust markers before overlays, as suggested by comments.
2351 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
2352 Remove redundant check before calling offset_intervals.
2354 2012-09-14 Martin Rudalics <rudalics@gmx.at>
2356 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
2357 current buffer (Bug#12387).
2359 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
2361 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
2363 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
2365 Use a more backwards-compatible timer format (Bug#12430).
2366 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
2367 vector element, not from the 4th, since PSECS is now at the end.
2368 (Fcurrent_idle_time): Doc fix.
2370 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
2372 Function to mark objects and remove killed buffers at once.
2373 * alloc.c (discard_killed_buffers): Rename to ...
2374 (mark_discard_killed buffers) ... new name. Add marking
2375 of remaining objects. Fix comment. Adjust users.
2376 (mark_object): Do not touch frame buffer lists here.
2377 * frame.c (delete_frame): Reset frame buffer lists here.
2379 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
2381 Better workaround for GNOME bug when --enable-gcc-warnings.
2382 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
2383 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
2384 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
2386 Simplify SIGIO usage (Bug#12408).
2387 The code that dealt with SIGIO was crufty and confusing, e.g., it
2388 played tricks like "#undef SIGIO" but these tricks were not used
2389 consistently. Simplify mostly by not #undeffing standard symbols,
2390 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
2391 or not as we please) rather than "defined SIGIO" (standard symbol
2392 that we probably shouldn't #undef).
2393 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
2394 Modules that need it can include it.
2395 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
2396 * dispextern.h (ignore_sigio): New decl.
2397 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
2398 unconditionally, since it's now a no-op if !USABLE_SIGIO.
2399 * emacs.c (shut_down_emacs):
2400 * keyboard.c (kbd_buffer_store_event_hold):
2401 Use ignore_sigio rather than invoking 'signal' directly.
2402 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
2404 (FIONREAD, SIGIO): Do not #undef.
2405 (tty_read_avail_input): Use #error rather than a syntax error.
2406 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
2407 for I_PIPE, used by SETUP_SLAVE_PTY.
2408 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
2409 * sysdep.c (croak): Remove; no longer needed. This bit of
2410 temporary code, with Fred N. Fish's comment that it's temporary,
2411 has been in Emacs since at least 1992!
2412 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
2413 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
2414 * syssignal.h (croak): Remove decl.
2415 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
2416 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
2417 now that we're termios-only.
2418 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
2419 * term.c (dissociate_if_controlling_tty): Use #error rather than
2422 Work around GCC and GNOME bugs when --enable-gcc-warnings.
2423 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
2424 to work around GNOME bug 683906.
2425 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
2426 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
2427 This works around GCC bug 54561.
2429 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
2431 More fixes for 'volatile' and setjmp/longjmp.
2432 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
2433 * image.c (struct png_load_context) [HAVE_PNG]: New type.
2434 (png_load_body) [HAVE_PNG]:
2435 (jpeg_load_body) [HAVE_JPEG]:
2436 New function, with most of the old parent function's body.
2437 (png_load) [HAVE_PNG]:
2438 (jpeg_load) [HAVE_JPEG]:
2439 Invoke the new function, to avoid longjmp munging our locals.
2440 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
2441 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
2442 longjmp is passed 2, as the C standard doesn't guarantee this.
2443 Instead, store the failure code into mgr->failure_code.
2445 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
2447 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
2448 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
2449 (syms_of_keyboard): Remove support for unread-command-char.
2451 2012-09-12 Eli Zaretskii <eliz@gnu.org>
2453 * w32proc.c (sys_kill): If PID is our process ID and the signal is
2454 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
2455 violation. (Bug#12426)
2457 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
2459 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
2461 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
2463 * eval.c: Add `inhibit-debugger'.
2464 (Qinhibit_debugger): New symbol.
2465 (call_debugger): Bind it instead of Qdebug_on_error.
2466 (maybe_call_debugger): Test Vinhibit_debugger.
2467 (syms_of_eval): Define inhibit-debugger.
2468 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
2469 (syms_of_xdisp): Remove inhibit-debug-on-message.
2471 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
2473 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
2474 If a nonvolatile local variable is written before a _longjmp to
2475 the frame containing the variable, and is read after the _longjmp,
2476 the value read is indeterminate. Some local variables of type
2477 'struct handler' and 'struct catchtag' are used in this way, so
2478 mark each of their slots as volatile if the slot can be set before
2479 _longjmp and read afterwards.
2480 * lisp.h (struct handler): var and chosen_clause are now volatile.
2481 (struct catchtag): val, next, and pdlcount are now volatile.
2483 * bidi.c (bidi_push_it, bidi_pop_it):
2484 * fns.c (copy_hash_table):
2485 * image.c (define_image_type):
2486 * keyboard.c (kbd_buffer_store_event_hold):
2487 * process.c (Fprocess_send_eof):
2488 * xfaces.c (x_create_gc) [HAVE_NS]:
2489 * xgselect.c (xg_select):
2490 Prefer assignment to memcpy when either will do.
2492 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
2493 Use pointer-to-a-pointer to simplify and avoid a NILP check each
2494 time an item is removed. No need to mark this function 'inline';
2495 the compiler knows better than we do.
2497 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
2499 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
2500 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
2501 to change_frame_size (Bug#12388).
2502 (windowDidResize:): Pass YES to updateFrameSize.
2504 * nsterm.h: Add delay parameter to updateFrameSize.
2506 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
2508 Discard killed buffers from deleted window and frame objects.
2509 This reduces an amount of references to killed buffers and
2510 helps GC to reclaim them faster.
2511 * alloc.c (discard_killed_buffers): New function.
2512 (mark_object): Use it for deleted windows and frames.
2513 (mark_object): If symbol's value is set up for a killed buffer
2514 or deleted frame, restore its global binding.
2515 * data.c (swap_in_global_binding): Add GC notice.
2516 (swap_in_symval_forwarding): Use convenient set_blv_where.
2517 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
2518 * window.h: ... to here.
2520 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
2522 Convenient macro to check whether the buffer is live.
2523 * buffer.h (BUFFER_LIVE_P): New macro.
2524 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
2525 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
2527 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2529 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
2530 composition cases (Bug#12364).
2532 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
2533 overhang of succeeding glyphs overlapping box cursor.
2535 * w32term.c (x_draw_glyph_string): Likewise.
2537 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
2539 Simplify, document, and port floating-point (Bug#12381).
2540 The porting part of this patch fixes bugs on non-IEEE platforms
2541 with frexp, ldexp, logb.
2542 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
2544 * floatfns.c: Simplify discussion of functions that Emacs doesn't
2545 support, by removing commented-out code and briefly listing the
2546 C89 functions excluded. The commented-out stuff was confusing
2547 maintenance, e.g., we thought we needed cbrt but it was commented out.
2548 (logb): Remove decl; no longer needed.
2549 (isfinite): New macro, if not already supplied.
2550 (isnan): Don't replace any existing macro.
2551 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
2552 are present on all C89 platforms.
2553 (Ffrexp): Do not special-case zero, as frexp does the right thing
2555 (Flogb): Do not use logb, as it doesn't have the desired meaning
2556 on hosts that use non-base-2 floating point. Instead, stick with
2557 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
2558 frexp, to avoid getting an unspecified result.
2560 * xdisp.c (Qinhibit_debug_on_message): Now static.
2562 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
2564 * nsterm.m (ns_update_begin): Set clip path to whole view by using
2565 NSBezierPath (Bug#12131).
2567 2012-09-10 Chong Yidong <cyd@gnu.org>
2569 * fns.c (Fdelq, Fdelete): Doc fix.
2571 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
2573 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
2574 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
2576 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
2578 * lisp.h (make_lisp_ptr): New macro to replace XSET.
2579 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
2582 2012-09-09 Eli Zaretskii <eliz@gnu.org>
2584 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
2585 left fringe if the window has a left margin. This avoids leaving
2586 traces of the cursor because its leftmost pixel is not drawn over.
2588 * dispnew.c (update_window_line): When the left margin area of a
2589 screen line is updated, set the redraw_fringe_bitmaps_p flag of
2590 that screen line. (Bug#12277)
2592 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
2594 Assume C89 or later for math functions (Bug#12381).
2595 This simplifies the code, and makes it a bit smaller and faster,
2596 and (most important) makes it easier to clean up signal handling
2597 since we can stop worring about floating-point exceptions in
2598 library code. That was a problem before C89, but the problem
2599 went away many years ago on all practical Emacs targets.
2600 * data.c, image.c, lread.c, print.c:
2601 Don't include <math.h>; no longer needed.
2602 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
2603 might be autoconfigured, as that never happens.
2605 * doprnt.c (DBL_MAX_10_EXP):
2606 * print.c (DBL_DIG):
2607 Remove. C89 or later always defines these.
2608 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
2609 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
2610 (arith_error, domain_error, domain_error2):
2611 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
2612 no longer needed -- we simply return what C returns. All uses removed.
2613 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
2615 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
2616 Remove. All uses expanded, as these macros are no longer used
2617 more than once and are now more trouble than they're worth.
2618 (Ftan): Use tan, not sin / cos.
2619 (Flogb): Assume C89 frexp.
2620 (fmod_float): Assume C89 fmod.
2621 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
2622 (init_floatfns): Remove. All uses removed.
2624 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
2626 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
2627 compositeToPoint for OSX < 10.6 (Bug#12390).
2629 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
2631 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
2632 This produces more-accurate results.
2634 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
2636 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
2637 changes (Bug#12088).
2639 2012-09-08 Chong Yidong <cyd@gnu.org>
2641 * syntax.c (Fstring_to_syntax): Doc fix.
2643 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
2645 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
2646 in the internal border.
2647 (x_set_window_size): Remove static variables and their usage.
2648 (ns_redraw_scroll_bars): Fix NSTRACE arg.
2649 (ns_after_update_window_line, ns_draw_fringe_bitmap):
2650 Remove fringe/internal border adjustment (Bug#11052).
2651 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
2652 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
2653 (ns_fix_rect_ibw): Remove.
2654 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
2655 (ns_dumpglyphs_box_or_relief): Ditto.
2656 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
2658 (ns_dumpglyphs_image): Ditto.
2659 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
2661 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
2662 their usage. Add fringe_extended_p and its use as in other terms.
2663 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
2664 scroll bar was removed.
2665 (updateFrameSize): New function.
2666 (windowDidResize): Move code to updateFrameSize and call it.
2668 * nsterm.h (EmacsView): Add updateFrameSize.
2670 2012-09-07 Chong Yidong <cyd@gnu.org>
2672 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
2674 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
2676 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
2678 More signal-handler cleanup (Bug#12327).
2679 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
2680 Problem introduced when merging patches. Noted by Eli Zaretskii in
2681 <http://bugs.gnu.org/12327#67>.
2682 * floatfns.c: Comment fix.
2683 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
2684 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
2685 and anyway the declaration is harmless even if SIGDANGER is not defined.
2686 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
2687 defined BROKEN_FIONREAD). systty.h formerly did this, but other
2688 source files not surprisingly expected syssignal.h to define, or
2689 not define, SIGIO, and it's cleaner to do it that way, for consistency.
2690 Include <sys/ioctl.h>, for FIONREAD.
2691 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
2692 This eliminates a problem whereby other files mysteriously had
2693 to include "syssignal.h" before including "systty.h" if they
2694 wanted to use "#ifdef SIGIO".
2696 2012-09-07 Eli Zaretskii <eliz@gnu.org>
2698 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
2700 * w32.c (sigemptyset): Empty the set.
2701 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
2703 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
2705 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
2707 * alloc.c (mark_buffer): Revert unsafe marking optimization.
2708 (mark_object): Likewise for frame objects.
2710 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
2712 * syssignal.h (handle_on_main_thread): Always declare,
2713 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
2714 This ports to platforms without HAVE_PTHREAD.
2716 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
2718 Signal-handler cleanup (Bug#12327).
2719 Emacs's signal handlers were written in the old 4.2BSD style with
2720 sigblock and sigmask and so forth, and this led to some
2721 inefficiencies and confusion. Rewrite these to use
2722 pthread_sigmask etc. without copying signal sets around. Also,
2723 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
2724 'signal', and instead use functions that do not attempt to take
2725 over the system name space. This patch causes Emacs's text
2726 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
2727 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
2728 Do not include <signal.h> or "syssignal.h", as these
2729 modules do not use signals.
2730 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
2731 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
2732 Do not include <signal.h>, as "syssignal.h" does that for us now.
2733 * atimer.c (sigmask_atimers): New function.
2734 (block_atimers, unblock_atimers): New functions,
2735 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
2737 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
2738 no longer needed here.
2739 * emacs.c (main): Inspect existing signal handler with sigaction,
2740 so that there's no need to block and unblock SIGHUP.
2741 * sysdep.c (struct save_signal): New member 'action', replacing
2742 old member 'handler'.
2743 (save_signal_handlers, restore_signal_handlers):
2744 Use sigaction instead of 'signal' to save and restore.
2745 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
2746 New function. All users of 'signal' modified to use set_sighandler
2747 if they're writeonly, and to use sys_signal if they're read+write.
2748 (emacs_sigaction_init, forwarded_signal): New functions.
2749 (sys_signal): Remove. All uses replaced by calls to sigaction
2750 and emacs_sigaction_init, or by direct calls to 'signal'.
2751 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
2752 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
2753 all uses replaced by pthread_sigmask etc. calls.
2754 * syssignal.h: Include <signal.h>.
2755 (emacs_sigaction_init, forwarded_signal): New decls.
2756 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
2757 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
2758 (sigmask, sys_sigmask): Remove; no longer needed.
2759 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
2760 (sigblock, sigunblock, sigfree):
2761 (sigsetmask) [!defined sigsetmask]:
2762 Remove. All uses replaced by pthread_sigmask.
2763 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
2764 no longer need to be replaced, and its typical old uses
2765 are now done via emacs_sigaction_init and sigaction.
2766 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
2767 (sys_sigdel): Remove; unused.
2768 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
2770 2012-09-06 Eli Zaretskii <eliz@gnu.org>
2772 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
2773 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
2775 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
2777 Explicitly mark buffer_defaults and buffer_local_symbols.
2778 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
2779 mark_local_symbols here.
2780 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
2781 since special buffers aren't marked here any more.
2782 (allocate_buffer): Chain new buffer with all_buffers here...
2783 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
2785 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
2786 (syms_of_buffer): Remove staticpro of the above.
2787 (init_buffer_once): Set names for buffer_defaults and
2788 buffer_local_symbols.
2790 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
2792 Use bool for booleans in font-related modules.
2793 * font.c (font_intern_prop, font_style_to_value)
2794 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
2795 (generate_otf_features, font_check_otf_features, font_check_otf)
2796 (font_match_p, font_list_entities, font_at):
2797 * fontset.c (fontset_id_valid_p, reorder_font_vector
2798 (fontset_find_font, Fset_fontset_font)
2799 (face_suitable_for_char_p) [0]:
2800 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
2801 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
2802 (m17n_flt_initialized, ftfont_shape_by_flt):
2803 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
2804 * nsfont.m (nsfont_draw):
2805 * w32font.c (w32font_draw):
2806 * w32term.c (x_draw_glyphless_glyph_string_foreground):
2807 Use bool for booleans.
2808 * font.h: Adjust to above API changes.
2809 (struct font, struct font_driver, struct font_driver_list):
2810 Use bool for booleans.
2811 (struct font): Remove useless member encoding_type.
2813 * fontset.c, xftfont.c: Omit unnecessary static decls.
2815 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
2817 * alloc.c (mark_object): Revert window marking code
2818 since it's unsafe for the Fset_window_configuration.
2820 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
2822 Fix race conditions with signal handlers and errno (Bug#12327).
2823 Be more systematic about preserving errno whenever a signal
2824 handler returns, even if it's not in the main thread. Do this by
2825 renaming signal handlers to distinguish between signal delivery
2826 and signal handling. All uses changed.
2827 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
2828 * data.c (deliver_arith_signal): Rename from arith_error.
2829 * dispnew.c (deliver_window_change_signal): Rename from
2830 window_change_signal.
2831 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
2832 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
2833 * keyboard.c (deliver_input_available_signal): Rename from
2834 input_available_signal.
2835 (deliver_user_signal): Rename from handle_user_signal.
2836 (deliver_interrupt_signal): Rename from interrupt_signal.
2837 * process.c (deliver_pipe_signal): Rename from send_process_trap.
2838 (deliver_child_signal): Rename from sigchld_handler.
2839 * atimer.c (handle_alarm_signal):
2840 * data.c (handle_arith_signal):
2841 * dispnew.c (handle_window_change_signal):
2842 * emacs.c (handle_fatal_signal, handle_danger_signal):
2843 * keyboard.c (handle_input_available_signal):
2844 * keyboard.c (handle_user_signal, handle_interrupt_signal):
2845 * process.c (handle_pipe_signal, handle_child_signal):
2846 New functions, with the actual signal-handling code taken from the
2847 original respective signal handlers, sans the sporadic attempts to
2848 preserve errno, since that's now done by handle_on_main_thread.
2849 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
2850 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
2851 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
2853 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
2854 Move initialization of main_thread to sysdep.c's init_signals.
2855 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
2856 our usage, and simplifies the mainline code.
2857 (record_child_status_change): New static function, as a helper
2858 for handle_child_signal, and with most of the old child handler's
2860 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
2861 (handle_child_signal): Use the above.
2862 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
2863 Moved here from emacs.c.
2864 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
2865 code moved here from emacs.c's main function.
2866 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
2867 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
2868 This lets callers save and restore errno properly.
2870 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
2872 Remove redundant or unused things here and there.
2873 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
2874 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
2875 * editfns.c (Fcompare_buffer_substrings): Likewise.
2876 * frame.h (struct terminal, struct font_driver_list):
2877 Remove redundant declarations.
2878 * window.h (Qleft, Qright): Likewise.
2880 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
2882 Do not mark objects from deleted buffers, windows and frames.
2883 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
2884 (mark_object): Likewise for windows and frames.
2886 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
2888 * alloc.c (valid_lisp_object_p): Treat killed buffers,
2889 buffer_defaults and buffer_local_symbols as valid objects.
2890 Return special value to denote them.
2892 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
2894 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
2895 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
2896 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
2897 (file_name_absolute_p, Fsubstitute_in_file_name):
2898 (check_executable, check_writable, Ffile_accessible_directory_p)
2899 (Fset_file_selinux_context, Fdefault_file_modes)
2900 (Finsert_file_contents, choose_write_coding_system)
2901 (Fwrite_region, build_annotations, a_write, e_write)
2903 * filelock.c (boot_time_initialized, get_boot_time)
2904 (get_boot_time_1, lock_file_1, within_one_second):
2905 * floatfns.c (in_float):
2906 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
2907 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
2908 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
2909 * lisp.h (struct Lisp_Hash_Table.cmpfn):
2910 * window.c (compare_window_configurations):
2911 Use bool for booleans.
2912 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
2913 (Fdefault_file_modes): Now mode_t, not int, for modes.
2914 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
2915 (internal_delete_file): Now returns void, not a (boolean) int,
2916 since nobody was looking at the return value.
2917 * lisp.h, window.h: Adjust to above API changes.
2919 * xdisp.c (set_message): Simplify and reindent last change.
2921 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
2923 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
2925 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
2927 * eval.c (call_debugger): Make the function non-static so that we
2928 can call it from set_message.
2930 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
2931 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
2933 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
2935 Give more-useful info on a fatal error (Bug#12328).
2936 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
2937 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
2938 of doing the work ourselves.
2939 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
2940 do most of the work.
2941 (fatal_error_backtrace): New function, taken from the guts
2942 of the old fatal_error_signal, but with a new option to output
2944 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
2945 info about the signal than just its number.
2946 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
2947 * sysdep.c: Include <execinfo.h>
2948 (emacs_backtrace): New function, taken partly from the previous
2949 code of the 'die' function.
2950 (emacs_abort): Call fatal_error_backtrace rather than abort.
2952 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
2954 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
2955 eager (load-time) macro-expansion.
2956 * lisp.mk (lisp): Add macroexp.
2958 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
2960 Simplify redefinition of 'abort' (Bug#12316).
2961 Do not try to redefine the 'abort' function. Instead, redo
2962 the code so that it calls 'emacs_abort' rather than 'abort'.
2963 This removes the need for the NO_ABORT configure-time macro
2964 and makes it easier to change the abort code to do a backtrace.
2965 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
2966 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
2967 Remove; sysdep.c's emacs_abort now takes its place.
2968 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
2969 'abort' changed to use 'emacs_abort'.
2970 * msdos.c (dos_abort) [defined abort]: Remove; not used.
2971 (abort) [!defined abort]: Rename to ...
2972 (emacs_abort): ... new name.
2973 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
2974 the place of the old 'abort' in emacs.c.
2975 * w32.c, w32fns.c (abort): Do not #undef.
2976 * w32.c (emacs_abort): Rename from w32_abort.
2978 2012-09-04 Eli Zaretskii <eliz@gnu.org>
2980 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
2981 offsets[j].dv, since the y axis of the screen coordinates points
2982 down, while the y axis of the font definition coordinates points
2983 up. This fixes display of Arabic diacritics such as KASRA and
2984 KASRATAN. (Bug#11860)
2986 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
2988 Be more systematic about _setjmp vs setjmp.
2989 * alloc.c (test_setjmp, mark_stack):
2990 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
2991 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
2992 (png_load, my_error_exit, jpeg_load):
2993 * process.c (send_process_trap, send_process):
2994 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
2995 The underscored versions are up to 30x faster on some hosts.
2996 Formerly, the code used setjmp+longjmp sometimes and
2997 _setjmp+_longjmp at other times, with no particular reason to
2998 prefer setjmp+longjmp.
3000 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
3002 Fix minor problem found by static checking.
3003 * buffer.c (Fdelete_all_overlays): Return nil.
3005 2012-09-03 Martin Rudalics <rudalics@gmx.at>
3007 * buffer.c (Fdelete_all_overlays): New function.
3009 2012-09-03 Chong Yidong <cyd@gnu.org>
3011 * gtkutil.c: Add extern decl for Qxft.
3013 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
3015 * emacs.c, eval.c: Use bool for boolean.
3016 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
3017 (malloc_using_checking) [DOUG_LEA_MALLOC]:
3018 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
3019 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
3020 (main, decode_env_path, Fdaemon_initialized):
3021 * eval.c (call_debugger, Finteractive_p, interactive_p):
3022 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
3023 (maybe_call_debugger, Fbacktrace):
3024 * process.c (read_process_output, exec_sentinel):
3025 Use bool for booleans.
3026 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
3027 All callers changed.
3028 * eval.c (interactive_p): Omit always-true boolean argument
3029 EXCLUDE_SUBRS_P. All callers changed.
3030 * dispextern.h, lisp.h: Reflect above API changes.
3031 * firstfile.c (dummy): Use the address of 'main', whose signature
3032 won't change, instead of the address of 'initialize', whose
3033 signature just changed from int to bool.
3034 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
3035 * msdos.c (fatal_error_in_progress): ... from here.
3036 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
3038 (redisplay_internal, unwind_redisplay): Simply clear
3039 REDISPLAYING_P when unwinding, instead of saving its previous,
3040 always-false value and then restoring it.
3042 Clean up some extern decls.
3043 Mostly, this hoists extern decls out of .c files and into .h files.
3044 That way, we're more likely to catch errors if the interfaces change.
3045 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
3046 declare xg_mark_data.
3047 * dispextern.h (x_frame_parm_handlers):
3049 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
3050 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
3051 (Qultra_bold, Qoblique, Qitalic):
3052 Move extern decl here from .c file.
3053 * alloc.c (xg_mark_data) [USE_GTK]:
3055 * eval.c (Qlexical_binding):
3056 * fns.c (time) [!HAVE_UNISTD_H]:

3062 * process.c (QCfamily, QCfilter):
3063 * widget.c (free_frame_faces):
3064 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
3065 * xfont.c (x_clear_errors):
3066 * xterm.c (x_frame_parm_handlers):
3067 Remove now-redundant extern decls.
3068 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
3069 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
3071 * xfaces.c: Remove unnecessary static decls.
3072 * xterm.c (updating_frame): Remove decl of nonexistent object.
3074 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
3075 when building globals.h, as the objects that are not built on
3076 this host are not needed to compile C files on this host.
3078 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
3080 * gtkutil.h: Remove prototype for x_wm_set_size_hint.
3082 * frame.h: Add missing prototype for x_wm_set_size_hint.
3084 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>

3088 (Fdocumentation, Fdocumentation_property, Fsnarf_documentation)
3089 (Fsubstitute_command_keys):

3094 (make_buffer_string, make_buffer_string_both)
3095 (Fsubst_char_in_region, Ftranslate_region_internal, Fformat):

3113 2012-09-02 Chong Yidong <cyd@gnu.org>
3115 * keymap.c (push_key_description): Print M-TAB as C-M-i
3118 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
3120 * makefile.w32-in (CCL_H, W32FONT_H): New macros.
3121 (ATIMER_H, FONT_H, $(BLD)/alloc.$(O), $(BLD)/callproc.$(O))

3126 ($(BLD)/w32font.$(O), $(BLD)/w32uniscribe.$(O)): Update dependencies.
3128 2012-09-01 Eli Zaretskii <eliz@gnu.org>
3130 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
3131 more than one grapheme cluster passed to the shaper: compute the
3132 offset adjustment values separately for each cluster. (Bug#11860)
3134 * image.c: Restore mistakenly removed inclusion of w32.h. Without
3135 it, GCC doesn't see prototypes of w32_delayed_load, and complains
3136 about implicit conversions from integer to pointer.
3138 2012-09-01 Daniel Colascione <dancol@dancol.org>
3140 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
3141 system used too early.
3143 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
3145 Better seed support for (random).
3146 * emacs.c (main): Call init_random.
3147 * fns.c (Frandom): Set the seed from a string argument, if given.
3148 Remove long-obsolete Gentzel cruft.

3159 x_set_tool_bar_lines, x_activate_menubar, and free_frame_menubar,
3160 all of which have been moved to common code.
3162 * xfaces.c: Include TERM_HEADER instead of listing all possible
3163 window-system headers.
3165 * w32xfns.c (x_sync): Correct definition of x_sync (a no-op here)
3168 * w32term.h (FRAME_X_WINDOW): Use FRAME_W32_WINDOW instead of
3169 directly accessing frame internals.
3171 * w32font.h: Include font.h. Define syms_of_w32font and
3174 * process.c: Include TERM_HEADER instead of listing all possible
3175 window-system headers.
3177 * nsterm.h: Remove declarations now in frame.h.
3178 Define FRAME_X_SCREEN, FRAME_X_VISUAL.
3180 * menu.c: Include TERM_HEADER instead of listing all possible
3181 window-system headers.
3183 * keyboard.h: Declare ignore_mouse_drag_p whenever we have a
3186 * keyboard.c: Include TERM_HEADER instead of listing all possible
3187 window-system headers.
3189 * image.c: Include TERM_HEADER instead of listing all possible
3190 window-system headers. Declare Vlibrary_cache when compiling for
3193 * gtkutil.h (xg_list_node_): Include xterm.h to pick up needed
3194 window system declarations.
3196 * frame.h: Move common functions here: set_frame_menubar,
3197 x_set_window_size, x_sync, x_get_focus_frame,
3198 x_set_mouse_position, x_set_mouse_pixel_position,
3199 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

3220 the current window system; include in list of objects to link into
3223 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
3225 Remove mark_ttys function and fix tty_display_info initialization.
3226 * lisp.h (mark_ttys): Remove prototype.
3227 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
3228 to mark_ttys because all possible values of 'top_frame' slot are
3229 the frames which are reachable from Vframe_list.
3230 * term.c (mark_ttys): Remove.
3231 (init_tty): Safely initialize 'top_frame' slot with Qnil.
3233 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
3235 Change struct frame bitfields from unsigned char to unsigned.
3236 * frame.h (struct frame): Change type of 'display_preempted',
3237 'visible', 'iconified', 'has_minibuffer', 'wants_modeline',
3238 'auto_raise', 'auto_lower', 'no_split', 'explicit_name',
3239 'window_sizes_changed', 'mouse_moved' and 'pointer_invisible'
3240 bitfields from unsigned char to unsigned.
3242 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
3244 Remove unused member of struct x_output and struct w32_output.
3245 * xterm.h (struct x_output): Remove unused field 'needs_exposure'.
3246 * w32term.h (struct w32_output): Likewise.
3248 2012-08-30 Jan Djärv <jan.h.d@swipnet.se>
3250 * gtkutil.c (x_wm_set_size_hint): Use 1 col for base_width so it
3251 does not become zero (Bug#12234).
3253 2012-08-30 Paul Eggert <eggert@cs.ucla.edu>
3255 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
3256 for GCC 4.7.1 x86-64.
3258 2012-08-30 Glenn Morris <rgm@gnu.org>
3260 * lread.c (init_lread): For out-of-tree builds, only add the
3261 source directory's site-lisp dir to the load-path if it exists,
3262 consistent with in-tree builds. (Bug#12302)
3264 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>
3266 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize
3267 button_values to NULL. Call setStykeMask so dialogs get a close button.
3268 (windowShouldClose:): Set window_closed.
3269 (dealloc): New member, free button_values.
3270 (process_dialog:): Make member function. Remove window argument,
3271 replace window with self. Count buttons and allocate and store values
3273 (addButton:value:row:): value is int with the name tag. Call setTag
3274 with tag. Remove return self, declare return value as void.
3275 (addString:row:): Remove return self, declare return value as void.
3276 (addSplit): Remove return self, declare return value as void.
3277 (clicked:): Remove return self, declare return value as void.
3278 Set dialog_return to button_values[seltag]. Code formatting change.
3279 (initFromContents:isQuestion:): Adjust call to process_dialog.
3280 Code formatting change.
3281 (timeout_handler:): Set timer_fired to YES.
3282 (runDialogAt:): Set timer_fired to NO.
3283 Handle click on close button as quit.
3285 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
3286 Add window_closed and button_values. Add void as return value for
3287 add(Button|String|Split). addButton takes int instead of Lisp_Object.
3288 Add process_dialog as new member.
3290 2012-08-28 Eli Zaretskii <eliz@gnu.org>
3292 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it
3293 is not one of the heaps we manage. (Bug#12242)
3295 2012-08-28 Glenn Morris <rgm@gnu.org>
3297 * eval.c (Fcalled_interactively_p): Doc fix. (Bug#11747)
3299 2012-08-28 Martin Rudalics <rudalics@gmx.at>
3301 * window.c (Fset_window_configuration): Remove handling of
3302 auto-buffer-name window parameter. Install revision of reverted
3305 2012-08-28 Dmitry Antipov <dmantipov@yandex.ru>
3307 Do not allow to set major mode for a dead buffer.
3308 * buffer.c (Fset_buffer_major_mode): Signal an error
3309 if the buffer is dead.
3310 (Fother_buffer, other_buffer_safely): Remove redundant
3313 2012-08-28 Dmitry Antipov <dmantipov@yandex.ru>
3315 Always use set_buffer_if_live to restore original buffer at unwind.
3316 * buffer.h (record_unwind_current_buffer): New function.
3317 * bytecode.c, dispnew.c, editfns.c, fileio.c, fns.c, insdel.c:
3318 * keyboard.c, keymap.c, minibuf.c, print.c, process.c, textprop.c:
3319 * undo.c, window.c: Adjust users.
3320 * buffer.c (set_buffer_if_live): Fix comment.
3322 2012-08-28 Dmitry Antipov <dmantipov@yandex.ru>
3324 Fix usage of set_buffer_internal.
3325 * buffer.h (set_buffer_internal): Make it BUFFER_INLINE.
3326 * buffer.c (set_buffer_if_live): Use set_buffer_internal.
3327 * coding.c (decode_coding): Omit redundant test.
3328 * fileio.c (decide_coding_unwind): Likewise.
3329 * fns.c (secure_hash): Likewise.
3330 * insdel.c (modify_region): Likewise.
3331 * keyboard.c (command_loop_1): Likewise.
3332 * print.c (PRINTFINISH): Likewise.
3333 * xdisp.c (run_window_scroll_functions): Use set_buffer_internal.
3335 2012-08-27 Paul Eggert <eggert@cs.ucla.edu>

3353 (change_frame_size_1, sit_for):
3354 Use bool for boolean.
3355 (clear_glyph_matrix_rows): Rename from enable_glyph_matrix_rows,
3356 and remove last int (actually boolean) argument, which was always 0.
3357 All callers changed.
3358 * dispextern.h, frame.h, lisp.h: Reflect above API changes.
3359 * dispextern.h (struct composition_it): Use bool for boolean.
3360 (struct glyph_matrix): Don't assume buffer sizes can fit in 'int'.
3361 (struct bidi_it): Use unsigned:1, not int, for boolean prev_was_pdf.
3362 * dired.c (file_name_completion):
3363 Use bool for boolean. (This was missed in an earlier change.)
3365 2012-08-27 Martin Rudalics <rudalics@gmx.at>
3367 * window.c (Fset_window_configuration): Revert first part of
3370 2012-08-27 Jan Djärv <jan.h.d@swipnet.se>
3372 * nsterm.h (NSPanel): New class variable dialog_return.
3374 * nsmenu.m (initWithContentRect:styleMask:backing:defer:):
3375 Initialize dialog_return.
3376 (windowShouldClose:): Use stop instead of stopModalWithCode.
3377 (clicked:): Ditto, and also set dialog_return (Bug#12258).
3378 (timeout_handler:): Use stop instead of abortModal. Send a dummy
3380 (runDialogAt:): Make ret Lisp_Object. Set it from dialog_return when
3383 2012-08-27 Paul Eggert <eggert@cs.ucla.edu>

3395 Use bool for booleans.
3396 * dired.c (file_name_completion):
3397 * process.h (fd_callback):
3398 Omit int (actually boolean) argument. It wasn't being used.
3400 * composite.h, lisp.h: Reflect above API changes.
3402 * cmds.c, coding.c: Use bool for booleans.

3424 * fileio.c (Finsert_file_contents):
3425 Use bool for booleans.
3426 * coding.h, lisp.h: Reflect above API changes.
3427 * coding.c: Remove unnecessary static function decls.
3428 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
3429 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
3430 not a boolean 'int', since callers never look at the return value.
3431 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
3432 * coding.h (decoding_buffer_size, encoding_buffer_size)
3433 (emacs_mule_string_char): Remove unused extern decls.
3434 (struct iso_2022_spec, struct coding_system):
3435 Use 'unsigned int : 1' for boolean fields, since there's more than one.
3436 (struct emacs_mule_spec): Remove unused field 'full_support'.
3437 All initializations removed.
3438 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
3440 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
3442 Fix spare memory change (Bug#12286).
3443 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
3444 (valid_lisp_object_p): Likewise.
3446 2012-08-27 Martin Rudalics <rudalics@gmx.at>
3448 * window.c (Fset_window_configuration): Record any window's old
3449 buffer if it's replaced (see Bug#8789). If the new current
3450 buffer doesn't appear in the selected window, go to its old
3453 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
3455 Special MEM_TYPE_SPARE to denote reserved memory.
3456 * alloc.c (enum mem_type): New memory type.
3457 (refill_memory_reserve): Use new type for spare memory.
3458 This prevents live_cons_p and live_string_p from incorrect
3459 detection of uninitialized objects from spare memory as live.
3461 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
3464 * Makefile.in (.PHONY): versioclean -> versionclean.
3466 Remove unused external symbols.
3467 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
3468 * window.c (Qwindow_valid_p, decode_valid_window):
3469 Now static, not extern.
3470 * data.c (Qinterval): Remove; unused.
3471 (syms_of_data): Do not define 'interval'.
3472 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
3473 * window.h (decode_valid_window):
3476 * character.c, charset.c, chartab.c: Use bool for booleans.
3477 * character.c (lisp_string_width, string_count_byte8)
3478 (string_escape_byte8):

3486 (char_table_set_range, optimize_sub_char_table)
3487 (map_sub_char_table):
3488 Use bool for boolean.
3489 * character.c (str_to_unibyte): Omit last boolean argument; it was
3490 always 0. All callers changed.
3491 * character.h, charset.h: Adjust to match previous changes.
3492 * character.h (char_printable_p): Remove decl of nonexistent function.
3493 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
3494 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
3495 are all boolean, so make them single-bit bitfields.
3497 * lisp.h (ASET): Remove attempt to detect side effects.
3498 It was meant to be temporary and it often doesn't work,
3499 because when IDX has side effects the behavior of IDX==IDX
3500 is undefined. See Stefan Monnier in
3501 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
3503 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
3505 * lisp.h (functionp): New function (extracted from Ffunctionp).
3506 (FUNCTIONP): Use it.
3507 * eval.c (Ffunctionp): Use it.
3509 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
3511 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
3512 as that's faster and simpler than static storage. Don't bother
3513 with the g_main_context_query overhead if g_main_context_pending
3514 says no events are pending.
3515 (gfds, gfds_size): Remove these static vars.
3516 (xgselect_initialize): Remove; no longer needed.
3517 All uses and decls removed.
3519 * emacs.c (fatal_error_signal_hook): Remove.
3520 All uses removed. This leftover from old code was always 0.
3522 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
3523 * casefiddle.c (casify_object, casify_region):
3524 * casetab.c (set_case_table):
3525 * category.c, category.h (word_boundary_p):
3526 * category.h (CHAR_HAS_CATEGORY):
3527 Use bool for booleans, instead of int.
3529 2012-08-25 Eli Zaretskii <eliz@gnu.org>
3531 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
3533 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
3535 On assertion failure, print backtrace if available.
3536 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
3537 (die) [ENABLE_CHECKING]: Print a backtrace if available.
3538 * Makefile.in (LIB_EXECINFO): New macro.
3541 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
3542 * bytecode.c (exec_byte_code):
3543 * callint.c (check_mark, Fcall_interactively):
3544 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
3545 (getenv_internal, sync_process_alive, call_process_exited):
3546 * lisp.h (USE_SAFE_ALLOCA):
3547 Use bool for booleans, instead of int.
3548 * lisp.h, process.h: Adjust prototypes to match above changes.
3549 * callint.c (Fcall_interactively): Don't assume the mark's
3550 offset fits in 'int'.
3552 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
3554 * buffer.c, buffer.h: Use bool for boolean.
3555 * buffer.c (reset_buffer_local_variables)

3561 (mmap_enlarge, mmap_set_vars):
3562 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
3563 Use bool for booleans, instead of int.
3564 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
3565 since the 1-or-0 return value is always ignored anyway.
3566 (mmap_initialized_p):
3567 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
3568 * buffer.h, lisp.h: Adjust prototypes to match above changes.
3570 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
3572 * bidi.c: Use bool for boolean.
3573 This is a bit more readable, and makes the text segment of bidi.o
3574 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
3575 Presumably it's faster too.
3576 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):

3581 (bidi_explicit_dir_char, bidi_level_of_next_char)
3582 (bidi_find_other_level_edge, bidi_move_to_visually_next):
3583 Use bool for booleans, instead of int.
3584 * dispextern.h (bidi_init_it, bidi_paragraph_init)
3585 (bidi_unshelve_cache): Adjust decls to match code.
3587 2012-08-23 Martin Rudalics <rudalics@gmx.at>
3589 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
3592 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
3594 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
3595 * atimer.h: Include <stdbool.h>.
3597 2012-08-22 Dan Nicolaescu <dann@gnu.org>
3599 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
3600 compile time tests instead of run time tests on systems that do
3602 (FRAME_MAC_P): Remove leftover from deleted code.
3603 * frame.c (syms_of_frame): Remove leftover from deleted code.
3605 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
3607 * nsterm.m (insertText:): Don't clear modifiers if code is space.
3609 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
3611 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
3612 Otherwise, the compiler complains about (A?B:C) where B is void
3613 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
3614 (fontset_add): Return void, for FONTSET_ADD.
3616 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
3618 * alloc.c: Use bool for booleans.
3619 (gc_in_progress, abort_on_gc)
3620 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
3621 (dont_register_blocks) [GC_MALLOC_CHECK]:
3622 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.

3624 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
3625 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
3626 (mark_stack, valid_pointer_p, make_pure_string)
3627 (Fgarbage_collect, survives_gc_p, gc_sweep):
3628 Use bool for booleans, instead of int.
3629 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
3630 Remove unused local.
3631 * alloc.c (PURE_POINTER_P):
3632 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
3633 * editfns.c (Fformat):
3634 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
3636 * fns.c (sweep_weak_table):
3637 * lisp.h (suppress_checking, push_message, survives_gc_p)
3638 (make_pure_string, gc_in_progress, abort_on_gc):
3639 * lread.c (readchar, read1):
3640 * print.c (Fprin1_to_string):
3641 * xdisp.c (push_message):
3642 Use bool for booleans affected directly or indirectly by
3645 Make recently-introduced setters macros.
3646 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
3647 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
3648 (set_fontset_default, set_fontset_fallback): Rename from their
3649 upper-case counterparts, and make them functions rather than macros.
3650 This is more consistent with the other recently-introduced setters.
3651 These don't need to be inline, since they're local.
3653 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
3655 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
3656 the loop (Bug#12247).
3658 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
3660 * lisp.h (vcopy): Use memcpy rather than our own loop.
3661 This fixes a performance regression introduced by the recent
3662 addition of vcopy. This means 'vcopy' will need to be modified
3663 for a copying collector, but that's OK. Also, tighten the
3664 checking in the assertion.

3714 2012-08-20 Eli Zaretskii <eliz@gnu.org>
3716 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5

3760 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
3762 Rely on <config.h> + <unistd.h> to declare 'environ',
3763 as gnulib does this if the system doesn't.
3764 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:

3799 * chartab.c, lisp.h (char_table_set, char_table_set_range):
3800 Return void, not Lisp_Object. Otherwise, the compiler

4635 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
4636 * w32.c (init_environment): Change the default values of many
4637 environment variables in dflt_envvars[] to NULL, to avoid pushing
4638 them into environment when they were not already defined.
4639 Remove the code that deletes site-lisp subdirectories from the default
4640 value of EMACSLOADPATH, as it is no longer needed.
4641 (check_windows_init_file): Now external, not static.
4642 Use Vload_path as is, without adding anything, as this function is now
4643 called when Vload_path is already set up.
4645 * w32.h (check_windows_init_file): Add prototype.
4647 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build
4648 directory, ignore the /*/i386/ tail in Vinvocation_directory, for
4649 compatibility with Posix platforms.
4650 (main): Move the call to check_windows_init_file to here from
4652 (decode_env_path) [WINDOWSNT]: Expand the %emacs_dir%/ prefix, if
4653 any, in the DEFALT argument into the root of the Emacs build or
4654 installation tree, as appropriate.
4656 * callproc.c (init_callproc_1): Call decode_env_path instead of
4657 doing its equivalent by hand.
4658 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
4659 the code that sets Vexec_path run on MS-Windows.
4661 * lread.c (init_lread): Add comments to #ifdef's.
4663 * msdos.c (dos_set_window_size, IT_update_begin)

4675 Remove unnecessary casts involving pointers.
4676 These casts are no longer needed now that we assume C89 or later,
4677 since they involve casting to or from void *.

4690 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
4691 Remove unnecessary pointer casts.
4692 * alloc.c (record_xmalloc): New function.
4693 * lisp.h (record_xmalloc): New decl.
4694 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
4695 more like a function. This is because the pointer cast is not
4696 needed. All uses changed.
4697 * print.c (print_string, print_error_message): Avoid length recalc.
4699 Improve fix for macroexp crash with debugging (Bug#12118).
4700 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
4701 ARRAY_MARK_FLAG when checking subscripts, because ASET is
4702 not supposed to be invoked from the garbage collector.
4703 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
4704 (gc_aset): New function, which is like ASET but can be
4705 used in the garbage collector.
4706 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)

4721 headers (most versions of MinGW w32api don't).
4722 (get_security_info, create_symbolic_link)
4723 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
4725 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
4726 in the argument file name.

4729 (sys_rename): Diagnose renaming of a symlink when the user doesn't
4730 have the required privileges.
4731 (get_file_security_desc_by_name): Rename from
4732 get_file_security_desc.
4733 (stat_worker): New function, with most of the guts of 'stat', and
4734 with addition of handling of symlinks and support for 'lstat'.
4735 If possible, get file's attributes and security information by
4736 handle, not by name. Produce S_IFLNK bit for symlinks, when
4737 called from 'lstat'.
4738 (stat, lstat): New functions, call 'stat_worker'.
4739 (symlink, readlink, careadlinkat): Rewritten to create and resolve
4740 symlinks when the underlying filesystem supports them.
4742 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
4744 Fix macroexp crash on Windows with debugging (Bug#12118).
4745 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
4746 checking subscripts; problem introduced with the recent
4747 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
4748 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
4749 since it's used in non-static inline functions now.
4751 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
4752 Don't assume buffer size fits in 'int'. Remove unused local.

4769 * category.c (CATEGORY_INLINE):
4770 * character.c (CHARACTER_INLINE):
4771 * charset.c (CHARSET_INLINE):
4772 * composite.c (COMPOSITE_INLINE):
4773 * dispnew.c (DISPEXTERN_INLINE):
4774 * sysdep.c (SYSTIME_INLINE):
4775 Define to EXTERN_INLINE, so that the corresponding functions
4776 are compiled into code.
4777 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
4778 (INLINE_HEADER_END): New macros.
4779 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

4799 hard-coding the path separator.
4801 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
4803 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
4804 This how ASET and AREF are supposed to work, and makes
4805 it easier to think about future improvements. See
4806 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
4807 * charset.h (set_charset_attr): New function.

5061 does that unconditionally. Remove file, which is now empty.
5063 * s/freebsd.h, s/gnu-linux.h, s/sol2-6.h, s/unixware.h:
5066 2012-07-30 Paul Eggert <eggert@cs.ucla.edu>
5068 Export to GDB most of lisp.h's remaining object-like macros.

5184 * w32inevt.c: Include w32inevt.h.
5185 (w32_read_console_input): New inline function, calls either

5187 w32_console_unicode_input.
5188 (fill_queue): Call w32_read_console_input instead of ReadConsoleInput.
5189 (w32_kbd_patch_key, key_event): Use the codepage returned by
5190 GetConsoleCP, rather than the ANSI codepage returned by GetLocaleInfo.

5222 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
5223 enumeration constants, as PURE and HEAP are too general, and clash
5224 with other headers and sources, such as gmalloc.c and the
5225 MS-Windows system headers. All users changed.
5227 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
5229 Revert last save_excursion_save and save_excursion_restore changes.
5230 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

5240 2012-07-27 Paul Eggert <eggert@cs.ucla.edu>
5242 Improve GDB symbol export (Bug#12036).
5243 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
5244 arms of an 'if', not using conditional expressions; otherwise GDB
5245 complains about the types in the unevaluated arm when the argument
5246 is an integer literal.
5247 (xgetint): Simplify expression.
5248 * alloc.c (gdb_make_enums_visible): New constant. This ports to
5249 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
5250 Zaretskii in <http://bugs.gnu.org/12036#13>.
5251 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
5252 needed now that we have gdb_make_enums_visible.
5253 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
5254 (enum enum_USE_LSB_TAG):
5255 New enum types, packaging up enums that need to be exported to GDB.

5273 * xdisp.c (syms_of_xdisp): Likewise.
5274 * xfns.c (syms_of_xfns): Likewise.
5276 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
5278 Fast save_excursion_save and save_excursion_restore.
5279 * lisp.h (struct Lisp_Excursion): New data type.
5280 (PVEC_EXCURSION): New pseudovector type.
5281 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
5282 to deal with it. Adjust comments.

5293 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
5295 Fix export of symbols to GDB (Bug#12036).
5296 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
5297 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
5298 emacs.c, as this is a more-suitable home. Had this been done earlier
5299 the fix for 12036 would have avoided some of the problems noted in
5300 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
5301 would have been more obvious.
5302 * emacs.c: Do not include <verify.h>; no longer needed.
5303 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
5304 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
5305 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
5306 Remove; now done in lisp.h.
5307 * lisp.h (PUBLISH_TO_GDB): New macro.

5311 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
5312 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
5313 not be usable in #if. This simplifies things.
5315 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
5317 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
5319 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
5321 Simplify export of symbols to GDB (Bug#12036).
5322 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
5323 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
5324 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
5325 Adjust to changes in lisp.h and emacs.c, by using
5326 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
5327 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
5328 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
5329 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
5330 instead of gdb_valbits.
5331 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
5332 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
5333 instead of gdb_array_mark_flag.
5334 (xboolvector): Get size from $->size, not $->header.size.
5335 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
5336 (xreload, hook-run, hookpost-run): Remove.
5337 * emacs.c: Include <verify.h>.
5338 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
5339 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
5341 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
5342 (gdb_USE_LSB_TAG): New enum constants.
5343 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
5344 Also define these as enum constants, so they're visible to GDB.
5345 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
5346 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
5347 as constants, so they're visible to GDB.
5348 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
5349 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
5350 Now enum constants, not macros, so they're visible to GDB.
5351 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
5352 more convenient now. All uses changed.
5353 (VALMASK) [USE_LSB_TAG]: Also define in this case.
5354 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
5356 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>
5358 Explicitly free restriction data that are not needed anymore.
5359 * editfns.c (save_restriction_restore): Free restriction data.
5361 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
5363 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
5364 add argument, tune behavior, and adjust all callers.
5366 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
5368 Use typedef for EMACS_INT, EMACS_UINT.
5369 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
5370 than macros. This simplifies debugging in the usual case, since
5371 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
5372 and it allows expressions involving EMACS_INT casts.
5373 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
5375 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>
5377 * nsterm.m (ns_read_socket): Return early if there is a modal
5380 2012-07-25 Martin Rudalics <rudalics@gmx.at>

5383 that FOCUS-FRAME can be omitted.
5385 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
5387 Adjust buffer text indirection counters at the end of Fkill_buffer.
5388 * buffer.c (Fkill_buffer): Adjust indirection counters when the
5389 buffer is definitely dead. This should really fix an issue reported
5390 by Christoph Scholtes again. (Bug#12007).
5391 (init_buffer_once): Initialize indirection counters of
5392 buffer_defaults and buffer_local_symbols (for sanity and safety).
5394 2012-07-24 Eli Zaretskii <eliz@gnu.org>
5396 * xdisp.c (init_iterator): Don't compute dimensions of truncation
5397 and continuation glyphs on tooltip frames, leave them at zero.
5398 Avoids continued lines in tooltips. (Bug#11832)
5400 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
5402 Simplify copy_overlay.
5403 * buffer.c (copy_overlay): Simplify. Use build_marker.

5409 or invalid. (Bug#12025)
5411 * window.c (decode_any_window): Disable CHECK_LIVE_FRAME test, as
5412 it signals an error when a tooltip frame is being created.
5414 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>

6193 The functional style also makes code easier to read and maintain.
6194 * systime.h: Include <sys/time.h> on all hosts, not just if

6230 (menu_separator_name_p):

6235 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
6236 Prefer snprintf to strncpy.
6237 * nsterm.m (ns_term_init):
6238 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
6239 * nsterm.m (ns_term_init):
6240 Avoid the need for strncpy, by using build_string or
6241 make_unibyte_string directly. Use dtoastr, not snprintf.
6242 * process.c (Fmake_network_process): Diagnose service names that
6243 are too long, rather than silently truncating them or creating
6244 non-null-terminated names.

6316 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
6317 O_RDONLY already includes it).
6319 Stop ns builds setting the EMACSLOADPATH environment variable.
6320 * nsterm.m (ns_load_path): Rename from ns_init_paths.
6321 Now it does not set EMACSLOADPATH, just returns the load-path string.
6322 * nsterm.h: Update accordingly.
6323 * lread.c [HAVE_NS]: Include nsterm.h.
6324 (init_lread) [HAVE_NS]: Use ns_load_path.
6325 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
6327 2012-07-09 Glenn Morris <rgm@gnu.org>
6329 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
6330 since the included bsd-common.h does so.
6332 Stop ns builds setting the EMACSPATH environment variable.
6333 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
6334 (ns_init_paths): Do not set EMACSPATH.
6335 * nsterm.h (ns_exec_path): Add it.
6336 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
6339 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
6341 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
6343 * process.c (wait_reading_process_output): 'waitchannels' was unset
6344 when read_kbd || !NILP (wait_for_cell); fix this.
6346 Add GCC-style 'const' attribute to functions that can use it.
6347 * character.h (char_resolve_modifier_mask):
6348 * keyboard.h (make_ctrl_char):
6349 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
6350 (init_character_once, next_almost_prime, init_fns, init_image)
6351 (flush_pending_output, init_sound):

6356 Declare the dummy function with ATTRIBUTE_CONST.
6357 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
6358 Add decls with ATTRIBUTE_CONST.
6360 Minor improvements to make_formatted_string.
6361 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
6362 where int is good enough, as vsprintf returns an int.
6363 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
6365 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
6367 Use make_formatted_string to avoid double length calculation.
6368 * lisp.h (make_formatted_string): New prototype.
6369 * alloc.c (make_formatted_string): New function.
6370 * buffer.c (Fgenerate_new_buffer_name): Use it.
6371 * dbusbind.c (syms_of_dbusbind): Likewise.
6372 * editfns.c (Fcurrent_time_zone): Likewise.
6373 * filelock.c (get_boot_time): Likewise.
6374 * frame.c (make_terminal_frame, set_term_frame_name)
6375 (x_report_frame_params): Likewise.
6376 * image.c (gs_load): Likewise.
6377 * minibuf.c (get_minibuffer): Likewise.

6387 (ns_init_paths): Do not set EMACSDATA, EMACSDOC.
6388 * nsterm.h (ns_etc_directory): Add it.
6389 * callproc.c [HAVE_NS]: Include nsterm.h.
6390 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
6392 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
6394 Move marker debugging code under MARKER_DEBUG.
6395 * marker.c (MARKER_DEBUG): Move marker debugging code under
6396 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
6397 for bootstrap with --enable-checking (~3x slowdown reported
6398 by Juanma Barranquero <lekktu@gmail.com>).
6399 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
6401 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
6403 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
6404 See <http://bugs.gnu.org/11825#29>.
6406 2012-07-08 Eli Zaretskii <eliz@gnu.org>
6408 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
6409 has no font, use the frame's font. (Bug#11813)
6410 (display_line): Add commentary about displaying truncation glyphs
6412 (produce_special_glyphs): Move here from term.c.
6414 * term.c (produce_special_glyphs): Move to xdisp.c.
6416 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
6419 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
6421 * xdisp.c (display_line): Avoid warning about implicit declaration
6424 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
6426 * lisp.h: Remove empty conditional.
6428 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
6430 * lread.c (load_path_check): Now static.
6432 Fix some minor --with-ns problems found by static checking.
6433 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
6434 (x_set_font) [!HAVE_X_WINDOWS]:
6435 * image.c (xpm_load_image) [HAVE_NS]:
6436 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
6437 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
6438 Remove unused local.
6439 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
6440 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
6441 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
6442 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
6443 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
6444 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
6445 Fix pointer signedness problem.
6446 * xfaces.c (FRAME_X_FONT_TABLE):
6447 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
6449 2012-07-07 Glenn Morris <rgm@gnu.org>
6451 * lread.c (load_path_check): New function, split from init_lread.
6452 (init_lread): Reorganize. Motivation:
6453 If EMACSLOADPATH is set, check/warn about that rather than the
6454 defaults, which we are not going to use. Hence we can remove
6455 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
6456 Don't warn if site-lisp directories are missing.
6457 If not installed, start from a blank load-path, since
6458 PATH_LOADSEARCH refers to the eventual installation directories.
6460 2012-07-07 Eli Zaretskii <eliz@gnu.org>
6462 Support truncation and continuation glyphs on GUI frames, when
6463 fringes are disabled. (Bug#11832)
6464 * xdisp.c (init_iterator): Get dimensions of truncation and
6465 continuation glyphs even if on GUI frames.
6466 Adjust it->last_visible_x on GUI frames when the left or right fringes,
6467 or both, are absent.
6468 (start_display, move_it_in_display_line_to): Handle the case of a
6469 GUI frame without a fringe to display continuation or truncation
6471 (insert_left_trunc_glyphs): Support GUI frames: make sure
6472 truncation glyphs overwrite enough glyphs from the current line to
6473 have sufficient space in pixels.
6474 (display_line): Support truncation and continuation glyphs on GUI
6475 frames. If some spare pixels are left on the line after inserting
6476 the truncation glyphs, fill that space with a stretch glyph of a
6477 suitably computed width.
6479 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
6480 produce_glyphs, to support GUI sessions.
6482 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
6484 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
6486 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
6488 Do not require float-time's arg to fit in time_t (Bug#11825).
6489 This works better on hosts where time_t is unsigned, and where
6490 float-time is applied to the (negative) difference between two times.
6491 * editfns.c (decode_time_components): Last arg is now double *,
6492 not int *, and means to store all the result as a double, without
6493 worrying about whether the seconds part fits in time_t.
6494 All callers changed.
6495 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
6496 All callers changed.
6497 (Ffloat_time): Do not fail merely because the specified time falls
6498 outside of time_t range.
6500 2012-07-07 Glenn Morris <rgm@gnu.org>
6502 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

6508 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
6509 Update dependencies.
6511 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
6513 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
6515 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).

6517 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
6518 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
6519 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
6520 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
6522 * xfont.c (compare_font_names): Redo to omit the need for casts.
6524 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
6526 * xfns.c (Fx_change_window_property): Doc fix.
6527 * w32fns.c (Fx_change_window_property): Doc fix.
6529 * w32fns.c (Fx_window_property): Accept the same arguments as the
6530 X Windows version. Doc fix.
6531 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
6533 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
6534 Eli Zaretskii <eliz@gnu.org>
6536 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
6537 Windows-specific code from nt/config.nt moved here.
6538 Obsolete settings removed.
6540 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
6542 * process.c: Avoid unnecessary calls to gettime.
6543 (wait_reading_process_output): Don't get the time of day
6544 when gobbling data immediately and not waiting, as there's no need
6545 for it in that case. This removes a FIXME.
6547 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
6549 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
6550 is defined (Bug#11768).
6552 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6554 Fix marker debugging code.
6555 * marker.c (byte_char_debug_check): Do not perform the check
6556 if buffer is not multibyte.
6557 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
6558 Call byte_char_debug_check with correct arguments.
6560 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6562 Compile marker debugging code only if ENABLE_CHECKING is defined.
6563 * marker.c (byte_char_debug_check, count_markers):
6564 Use only if ENABLE_CHECKING is defined.
6565 (byte_debug_flag): Remove.
6566 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
6567 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
6569 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6571 Avoid code repetition in marker-related functions.
6572 * marker.c (attach_marker): New function.
6573 (Fset_marker, set_marker_restricted, set_marker_both)
6574 (set_marker_restricted_both): Use it.
6575 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
6576 Consistently rename charno to charpos.
6577 (marker_position): Add eassert.
6578 (marker_byte_position): Convert to eassert.

6590 * lisp.h (build_marker): New prototype.
6591 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
6592 * composite.c (autocmp_chars): Likewise.
6593 * editfns.c (buildmark): Remove.
6594 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
6595 (save_restriction_save): Use build_marker.
6596 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
6597 * window.c (save_window_save): Likewise.
6599 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6601 Do not use Fdelete_overlay in delete_all_overlays
6602 to avoid redundant calls to unchain_overlay.
6603 * buffer.c (drop_overlay): New function.
6604 (delete_all_overlays, Fdelete_overlay): Use it.
6605 * minibuf.c (get_minibuffer): Fix comment.
6607 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
6609 Port to OpenBSD 5.1 amd64.
6610 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
6611 This is needed for OpenBSD, and should be harmless on all BSD systems.
6612 Also, include <sys/sysctl.h>, as it should be available on all
6613 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
6614 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
6615 use p_pid member, not kp_proc.pid.
6617 2012-07-06 Glenn Morris <rgm@gnu.org>
6619 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
6621 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
6623 More xmalloc and related cleanup.
6624 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
6625 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:

6630 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:
6631 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
6632 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
6634 Omit needless casts involving void * pointers and allocation.
6635 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
6636 as the former is more robust if P's type is changed.
6637 Prefer xzalloc to xmalloc + memset 0.
6638 Simplify malloc-or-realloc to realloc.
6639 Don't worry about xmalloc returning a null pointer.
6640 Prefer xstrdup to xmalloc + strcpy.
6641 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
6643 * keyboard.c (apply_modifiers_uncached): Prefer local array to
6644 alloca of a constant.
6646 2012-07-05 Eli Zaretskii <eliz@gnu.org>
6648 * xdisp.c (display_line): Fix horizontal pixel coordinates when
6649 hscroll is larger than the line width. Fixes long and futile
6650 looping inside extend_face_to_end_of_line (on a TTY) producing
6651 glyphs that are not needed and thrown away.
6653 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
6655 * marker.c (set_marker_restricted_both): Simplify by using

6669 followed by gtk_box_set_homogeneous (Bug#11768).
6670 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
6671 (update_theme_scrollbar_width, xg_create_scroll_bar):
6672 Use gtk_scrollbar_new (Bug#11768).
6673 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
6674 (is_box_type): New function (Bug#11768).
6675 (xg_tool_item_stale_p): Call is_box_type.
6676 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
6677 with default display (Bug#11768).
6679 2012-07-05 Eli Zaretskii <eliz@gnu.org>
6681 * xdisp.c (window_hscroll_limited): New function.
6682 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
6683 coordinates when window's hscroll is set to insanely large
6686 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
6688 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
6689 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
6691 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
6694 * lisp.h (xzalloc): New prototype. Omit needless casts.
6695 * alloc.c (xzalloc): New function. Omit needless casts.

6750 Problem reported by Troels Nielsen in
6751 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
6753 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
6755 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
6756 This should be fixed in a better way; see Eli Zaretskii in
6757 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
6758 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
6760 * fileio.c (time_error_value): Rename from special_mtime.
6761 The old name's problems were noted by Eli Zaretskii in
6762 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
6764 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
6765 This variable's comment says Emacs needs at least one GDB-visible
6766 symbol of type enum pvec_type, to work around GDB problems.
6767 The symbol's value doesn't matter.
6769 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
6770 that causes compilation to fail on pre-C99 compilers.
6772 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
6774 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

6783 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
6785 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
6786 * lisp.h (enum pvec_type): Use fewer bits.
6787 (PSEUDOVECTOR_SIZE_BITS): New constant.
6788 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
6789 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
6790 change in pvec_type.
6791 (PSEUDOVECTOR_TYPEP): New macro.
6792 (TYPED_PSEUDOVECTORP): Use it.

6797 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
6798 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
6799 (sweep_vectors): Use it. Use local var `total_bytes' instead of
6800 abusing vector->header.next.nbytes.
6801 (live_vector_p): Use PVEC_TYPE.
6802 (mark_object): Adapt code to extract pvectype. Use switch.
6804 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
6806 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
6807 Tighten new eassert a bit.
6809 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
6811 Fix compilation with --enable-gcc-warnings and -O1
6813 * doprnt.c (doprnt): Change type of tem to int, initialize
6814 to avoid compiler warning. Add eassert.
6815 * search.c (simple_search): Initialize match_byte to avoid
6816 compiler warning. Add eassert.
6818 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
6820 Avoid weird behavior with large horizontal scrolls.
6821 Without this change, for example, large hscroll values would
6822 mess up Emacs's display on Fedora 15 x86, presumably due to
6823 overflows in int calculations in the display code.
6824 Also, if buffers had long lines, Emacs would freeze.
6825 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
6826 (set_window_hscroll): New function, containing the old guts of
6827 Fset_window_hscroll. Return the clipped value.
6828 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
6829 This avoids the need to check against PTRDIFF_MAX.
6831 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
6833 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
6835 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
6837 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
6839 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
6840 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
6841 since GCC 4.4.6 issues a bogus warning for them.
6843 Fix bugs in file timestamp newness comparisons.
6844 * fileio.c (Ffile_newer_than_file_p):
6845 * lread.c (Fload): Use full timestamp resolution of files,
6846 not just the 1-second resolution, so that files that are only
6847 slightly newer still count as newer.
6848 * fileio.c (Ffile_newer_than_file_p): Don't assume file
6849 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
6851 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
6853 * fileio.c: Improve handling of file time marker. (Bug#11852)
6854 (special_mtime): New function.
6855 (Finsert_file_contents, Fverify_visited_file_modtime):
6856 Use it to set special mtime values consistently.
6858 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
6860 * fileio.c (Finsert_file_contents): Properly handle st_mtime
6861 marker for non-existing file. (Bug#11852)
6863 2012-07-03 Glenn Morris <rgm@gnu.org>
6865 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
6866 and did not make it into globals.h).
6868 2012-07-03 Tom Tromey <tromey@redhat.com>
6870 * window.c (Fset_window_margins, Fset_window_fringes)

6895 * intervals.h: Remove EXFUNs.
6896 * fontset.h: Remove EXFUN.
6897 * font.h: Remove EXFUNs.
6898 * dosfns.c (system_process_attributes): Remove EXFUN.
6899 * keymap.h: Remove EXFUNs.
6900 * lisp.h: Remove EXFUNs.
6901 * w32term.h: Remove EXFUNs.
6902 * window.h: Remove EXFUNs.
6903 * xsettings.h: Remove EXFUN.
6904 * xterm.h: Remove EXFUN.
6906 2012-07-03 Glenn Morris <rgm@gnu.org>
6908 * lisp.h (Frandom): Make it visible to C.
6909 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
6910 buffer for invisible buffers. (Bug#1229)

6914 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
6915 values which aren't power of 2.
6916 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
6917 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
6920 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
6922 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
6924 * alloc.c (mark_object): Revert part of last patch to use `switch'.
6926 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
6928 * alloc.c (allocate_vector_block): Remove redundant
6929 calls to mallopt if DOUG_LEA_MALLOC is defined.
6930 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
6931 avoid calls to mallopt if zero_vector is returned.
6933 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
6935 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
6936 is enabled, avoid dereferencing NULL current_sblock if
6939 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
6941 Cleanup basic buffer management.
6942 * buffer.h (struct buffer): Change layout to use generic vector
6943 marking code. Fix some comments. Change type of 'clip_changed'
6944 to bitfield. Remove unused #ifndef old.
6945 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
6946 (GET_OVERLAYS_AT): Fix indentation.
6947 (for_each_per_buffer_object_at): New macro.
6948 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
6949 (Fbuffer_local_variables): Use it.
6950 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
6951 * alloc.c (allocate_buffer): Adjust to match new layout of
6952 struct buffer. Fix comment.
6953 (mark_overlay): New function.
6954 (mark_buffer): Use it. Use mark_vectorlike to mark normal
6955 Lisp area of struct buffer.
6956 (mark_object): Use it. Adjust marking of misc objects
6957 and related comments.
6959 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
6961 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
6962 wrapper that is not needed because the wrapped code is a no-op (zero
6963 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
6964 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
6966 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
6968 * alloc.c (mark_buffer): Simplify. Remove prototype.
6969 (mark_object): Add comment. Reorganize marking of vector-like
6970 objects. Use CHECK_LIVE for all vector-like objects except buffers
6971 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
6972 Avoid redundant calls to mark_vectorlike for bool vectors.
6974 2012-06-30 Glenn Morris <rgm@gnu.org>
6976 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
6978 * epaths.in (PATH_SITELOADSEARCH): New.
6979 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
6980 This is rather than relying on --enable-locallisppath elements
6981 having "site-lisp" in their names. (Bug#10208#25, 11658)
6983 2012-06-30 Eli Zaretskii <eliz@gnu.org>
6985 * w32proc.c (sys_select): Accept and ignore one more argument.
6987 * w32.c (emacs_gnutls_pull): Call select with one more argument.
6989 * sysselect.h [DOS_NT]: Don't include sys/select.h.
6990 (pselect) [!MS_DOS]: Redirect to sys_select.
6992 * sysdep.c: Don't include dos.h and dosfns.h.
6994 * process.c (sys_select):
6995 * msdos.c (sys_select): Accept one more argument and ignore it.
6997 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
6998 adapt data types and code to that.
7001 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
7002 which clashes with the gnulib function of the same name.
7004 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
7006 * font.c (font_style_to_value, font_style_symbolic)
7007 (font_prop_validate_style): Add type checks for values in
7010 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
7012 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
7015 2012-06-29 Eli Zaretskii <eliz@gnu.org>
7017 * xdisp.c (try_window_id): Undo last change.
7019 * w32.c (getwd): Adjust commentary about startup_dir.
7020 (init_environment): Always call sys_access, even in non-MSVC
7021 builds. Don't chdir to the directory of the Emacs executable.
7022 This undoes code from 1997 which was justified by the need to
7023 "avoid conflicts when removing and renaming directories". But its
7024 downside was that every relative file name was being interpreted
7025 relative to the directory of the Emacs executable, which can never
7026 be TRT. In particular, it broke sys_access when called with
7027 relative file names.
7028 (sys_access): Map GetLastError to errno.
7030 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
7032 * window.h (struct window): Change type of 'fringes_outside_margins'

7036 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
7039 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>

7042 Add QUIT to make the loop interruptible.
7044 2012-06-29 Glenn Morris <rgm@gnu.org>
7046 * charset.c (init_charset): Make lack of etc/charsets fatal.
7048 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
7050 * editfns.c (region_limit): Fix type mismatch.
7052 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
7054 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
7055 undefined. Convert from xassert to eassert.
7056 * nsmenu.m: Convert from xassert to eassert.
7057 * nsterm.m: Likewise.
7059 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
7061 * editfns.c (region_limit): Clip to narrowing (bug#11770).
7063 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
7065 Avoid integer overflow on scroll-left and scroll-right.
7066 * window.c (HSCROLL_MAX): New macro.
7067 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
7068 overflow when requested scroll falls outside ptrdiff_t range.
7070 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
7072 * window.h (struct window): Change type of 'hscroll',
7073 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
7074 'last_modified' and 'last_overlay_modified' to EMACS_INT.
7075 Adjust users accordingly.
7076 * xdisp.c (try_cursor_movement): Replace type check with eassert.
7077 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
7078 from EMACS_INT to ptrdiff_t.
7079 (make_window): Omit redundant initialization.
7081 2012-06-28 Juanma Barranquero <lekktu@gmail.com>

7085 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>

7154 * alloc.c (allocate_string): Omit intervals initialization.
7155 * alloc.c (make_uninit_multibyte_string): Initialize intervals
7156 as in make_pure_string and make_pure_c_string.

7212 * alloc.c: Remove build_string.
7213 * lisp.h: Define build_string as static inline. This provides
7214 a better opportunity to optimize away calls to strlen when the
7215 function is called with compile-time constant argument.
7216 * image.c (imagemagick_error): Convert to build_string.
7217 * w32proc.c (sys_spawnve): Likewise.
7218 * xterm.c (x_term_init): Likewise.
7220 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
7222 Use sprintf return value instead of invoking strlen on result.
7223 In the old days this wasn't portable, since some sprintf
7224 implementations returned char *. But they died out years ago and
7225 Emacs already assumes sprintf returns int.
7226 Similarly for float_to_string.
7227 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
7228 * ccl.c (ccl_driver):
7229 * character.c (string_escape_byte8):

7234 * xfns.c (syms_of_xfns):
7235 Use sprintf or float_to_string result to avoid need to call strlen.
7236 * data.c (Fnumber_to_string):
7237 Use make_unibyte_string, since the string must be ASCII.
7238 * lisp.h, print.c (float_to_string): Now returns int length.
7239 * term.c (produce_glyphless_glyph):
7240 Use sprintf result rather than recomputing it.
7242 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
7243 * Makefile.in (ALL_CFLAGS):

7275 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

7346 See <http://bugs.gnu.org/9000#51>.
7348 2012-06-23 Eli Zaretskii <eliz@gnu.org>

7411 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
7413 Support higher-resolution time stamps (Bug#9000).
7414 The time stamps are only nanosecond-resolution at the C level,
7415 since that's the best that any real-world system supports now.
7416 But they are picosecond-resolution at the Lisp level, as that's
7417 easy, and leaves room for future OS improvements.
7419 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
7422 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
7423 Don't get current time unless it's needed.
7425 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
7426 now provides it if it's absent.
7427 (start_atimer): Port to higher-res time stamps.
7428 Check for time stamp overflow. Don't get current time more
7429 often than is needed.
7431 * buffer.h (struct buffer): Buffer modtime now has high resolution.
7432 Include systime.h, not time.h.
7433 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
7435 * dired.c: Include stat-time.h.
7436 (Ffile-attributes): File times now have higher resolution.
7438 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
7439 (struct image): Timestamp now has higher resolution.
7441 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
7442 has at least microseconds now. All uses removed.
7443 (update_frame, update_single_window, update_window, update_frame_1)
7444 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
7445 (duration_to_sec_usec): Remove; no longer needed.
7447 * editfns.c (time_overflow): Now extern.
7448 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
7449 (float-time, Fformat_time_string, Fcurrent_time_string)
7450 (Fcurrent_time_zone): Accept and generate higher-resolution
7452 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
7453 (decode_time_components, lisp_seconds_argument): New functions.
7454 (make_time): Now static.
7455 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
7456 Report an error if the time is invalid, rather than having the caller
7459 * fileio.c: Include <stat-time.h>
7460 (Fcopy_file): Copy higher-resolution time stamps.
7461 Prefer to set the time stamp via a file descriptor if that works.
7462 (Fset_file_times, Finsert_file_contents, Fwrite_region)
7463 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
7464 (Fvisited_file_modtime, Fset_visited_file_modtime):
7465 Support higher-resolution time stamps.
7467 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
7469 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
7471 * image.c (prepare_image_for_display, clear_image_cache)
7472 (lookup_image): Port to higer-resolution time stamps.
7474 * keyboard.c (start_polling, bind_polling_period):
7475 Check for time stamp overflow.
7476 (read_char, kbd_buffer_get_event, timer_start_idle)
7477 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
7478 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
7479 Port to higher-resolution time stamps. Do not assume time_t is signed.
7480 (decode_timer): New function. Timers are now vectors of length 9,
7481 not 8, to accommodate the picosecond component.
7482 (timer_check_2): Use it.
7484 * nsterm.m (select_timeout, timeval_subtract): Remove.
7485 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
7486 as they're a bit more accurate and handle overflow better.
7487 (ns_select): Change prototype to be compatible with pselect.
7488 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
7489 * nsterm.h (ns_select): Adjust prototype.
7491 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
7492 us-resolution time stamps.
7493 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
7495 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
7497 * lisp.h (time_overflow): New decl.
7498 (wait_reading_process_output): First arg is now intmax_t, not int,
7499 to accommodate larger waits.
7501 * process.h (struct Lisp_Process.read_output_delay):
7502 Now counts nanoseconds, not microseconds.
7503 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
7505 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
7506 (wait_reading_process_output):
7507 Port to ns-resolution time stamps.
7508 (Faccept_process_output, wait_reading_process_output):
7509 Check for time stamp overflow. Do not assume time_t is signed.
7510 (select_wrapper): Remove; we now use pselect.
7511 (Fprocess_attributes): Now generates ns-resolution time stamps.
7513 * sysdep.c: Include utimens.h. Don't include utime.h
7514 or worry about struct utimbuf; gnulib does that for us now.
7515 (gettimeofday): Remove; gnulib provides a substitute.
7516 (make_timeval): New function.
7517 (set_file_times): Now sets ns-resolution time stamps.
7518 New arg FD; all uses changed.
7519 (time_from_jiffies, ltime_from_jiffies, get_up_time)
7520 (system_process_attributes):
7521 Now returns ns-resolution time stamp. All uses changed.
7522 Check for time stamp overflow.
7524 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
7525 provides a substitute now.
7527 * systime.h: Include timespec.h rather than sys/time.h and time.h,
7528 since it guarantees struct timespec.
7529 (EMACS_TIME): Now struct timespec, so that we can support
7530 ns-resolution time stamps.
7531 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
7532 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
7533 (EMACS_USECS): Remove.
7534 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
7535 so multiply the arg by 1000 before storing it.
7536 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
7538 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
7539 Port to ns-resolution time stamps.
7540 (EMACS_TIME_NEG_P): Remove; replaced by....
7541 (EMACS_TIME_SIGN): New macro.
7542 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
7543 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
7544 (set_file_times, make_time, lisp_time_argument): Adjust signature.
7545 (make_timeval, make_lisp_time, decode_time_components): New decls.
7546 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
7547 that it mishandled time_t overflow. You can't compare by subtracting!
7548 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
7549 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
7551 * term.c: Include <sys/time.h>.
7552 (timeval_to_Time): New function, for proper overflow wraparound.

7555 * undo.c (record_first_change): Support higher-resolution time stamps
7557 (Fprimitive_undo): Use them when restoring time stamps.
7559 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
7560 (w32_get_internal_run_time):
7561 Port to higher-resolution Emacs time stamps.
7562 (ltime): Now accepts single 64-bit integer, as that's more convenient
7565 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
7567 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
7568 for compatibility with pselect. Support ns-resolution time stamps.
7570 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
7572 * xselect.c (wait_for_property_change, x_get_foreign_selection):
7573 Check for time stamp overflow, and support ns-resolution time stamps.
7575 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
7576 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
7577 (timeval_subtract): Remove; no longer needed.
7578 (XTflash, XTring_bell, x_wait_for_event):
7579 Port to ns-resolution time stamps. Don't assume time_t is signed.
7581 2012-06-22 Chong Yidong <cyd@gnu.org>

7585 2012-06-22 Eli Zaretskii <eliz@gnu.org>
7587 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
7588 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
7589 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
7590 staticidx goes up to 1597 out of 1600 = 0x640.)
7592 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
7594 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
7595 Otherwise, the umask might be mistakenly 0 while handling input signals.

7616 (unwind_format_mode_line): Restore them.
7617 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
7619 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
7620 since tty frames can be explicitly named.
7621 (prepare_menu_bars): Likewise.
7623 * term.c (Ftty_top_frame): New function.
7625 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

7628 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
7629 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
7630 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
7631 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
7632 (METER_1, METER_2): Simplify.
7634 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>

7638 2012-06-18 Martin Rudalics <rudalics@gmx.at>
7640 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
7641 gets killed during executing of this function (Bug#11665).
7642 Try to always return Qt when the buffer has been actually killed.
7643 (Vkill_buffer_query_functions): In doc-string say that functions
7644 run by this hook should not change the current buffer.
7646 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
7648 Fix recently-introduced process.c problems found by static checking.

7666 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
7668 * lisp.h (eassert): Assume C89 or later.
7669 This removes the need for CHECK.
7670 (CHECK): Remove. Its comments about always evaluating its
7671 argument were confusing, as 'eassert' typically does not evaluate
7674 * coding.c (produce_chars): Use ptrdiff_t, not int.
7676 * xterm.c (x_draw_underwave): Check for integer overflow.
7677 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

7861 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
7862 code works fine either way, and efficiency is not a concern here,
7863 as the union type is for debugging, not for production.
7864 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
7865 Use an inline function on all platforms when using the union type,
7866 since this is simpler and 'static inline' can be used portably
7868 (LISP_INITIALLY_ZERO): New macro.
7869 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.

7977 * alloc.c (allocate_vectorlike): Fix last change.

8008 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
8010 * doprnt.c (doprnt): Truncate multibyte char correctly.
8011 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
8012 would mishandle a string argument "Xc" if X was a multibyte
8013 character of length 2: it would truncate after X's first byte
8014 rather than including all of X.
8016 2012-06-06 Chong Yidong <cyd@gnu.org>

8067 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
8068 Convert pctcpu and pctmem to Lisp float properly.
8069 Let the compiler fold better, as 100.0/0x8000 is exact.

8073 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of

8088 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
8089 fields from Lisp_Object to bitfield. Adjust users accordingly.

8097 and 'double' in a couple of places.
8099 2012-05-31 Eli Zaretskii <eliz@gnu.org>
8101 * xdisp.c (handle_stop): Detect whether we have overlay strings
8102 loaded by testing it->current.overlay_string_index to be
8103 non-negative, instead of checking whether n_overlay_strings is
8104 positive. (Bug#11587)
8106 2012-05-31 Chong Yidong <cyd@gnu.org>
8108 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

8114 * search.c (search_buffer): Remove calls to
8115 r_alloc_inhibit_buffer_relocation, as it is now called by
8116 maybe_unify_char, which was the cause of relocation of buffer text
8119 2012-05-31 Eli Zaretskii <eliz@gnu.org>
8121 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
8122 for the duration of call to load_charset, to avoid problems with
8123 callers of maybe_unify_char that access buffer text through C
8126 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
8127 decrement the inhibition flag, instead of just setting or
8130 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
8132 Remove obsolete '#define static' cruft.
8133 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
8134 This #undef was "temporary" in 2000; it is no longer needed
8135 now that '#define static' has gone away.
8136 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
8137 (gray_bitmap_bits): Remove; no longer needed.
8138 All uses replaced with definiens.

8182 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
8183 Bug#9642, but explicitly check that the buffer the overlay would
8184 be moved to is live and rearrange lines to make sure that errors
8185 will not put the overlay in an inconsistent state.
8186 (Fdelete_overlay): Cosmetics.
8188 2012-05-28 Eli Zaretskii <eliz@gnu.org>
8190 * w32term.c (my_bring_window_to_top): New function.
8191 (x_raise_frame): Use handle returned by DeferWindowPos, which

8225 Only r_alloc_inhibit_buffer_relocation needed to be added;
8226 the others were already declared.
8228 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
8229 before checking whether it's out of range. Put the check inside
8231 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
8233 2012-05-27 Ken Brown <kbrown@cornell.edu>
8235 * callproc.c (Fcall_process): Restore a line that was accidentally
8236 commented out in the 2011-02-13 change (bug#11547).
8238 2012-05-27 Eli Zaretskii <eliz@gnu.org>
8240 * lisp.h [REL_ALLOC]: Add prototypes for external functions
8241 defined on ralloc.c.
8243 * buffer.c [REL_ALLOC]: Remove prototypes of
8244 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
8245 they are now on lisp.h.
8247 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
8249 * search.c (search_buffer): Use it to inhibit relocation of buffer
8250 text while re_search_2 is doing its job, because re_search_2 is
8251 passed C pointers to buffer text. (Bug#11519)
8253 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
8256 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
8257 state after an additional call to move_it_in_display_line_to, keep
8258 the values of it->max_ascent and it->max_descent found for the
8260 (pos_visible_p): Revert the comparison against bottom_y to what it
8261 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
8264 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
8266 Fix coding-related core dumps with gcc -ftrapv.
8267 The code was computing A - B, where A and B are pointers, and B is
8268 random garbage. This can lead to core dumps on platforms that
8269 have special pointer registers, and it also leads to core dumps on
8270 x86-64 when compiled with gcc -ftrapv. The fix is to compute
8271 A - B only when B is initialized properly.
8272 * coding.c (coding_set_source, coding_set_destination): Return void.
8273 (coding_change_source, coding_change_destinations): New functions,
8274 with the old behaviors of coding_set_source and coding_set_destination.
8275 All callers that need an offset changed to use these new functions.
8277 2012-05-26 Glenn Morris <rgm@gnu.org>
8279 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)

8283 Extend mouse support on W32 text-mode console.
8284 * xdisp.c (draw_row_with_mouse_face):
8285 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
8287 * w32console.c: Include window.h.
8288 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
8290 (initialize_w32_display): Initialize mouse-highlight data.
8292 * w32inevt.c: Include termchar.h and window.h.
8293 (do_mouse_event): Support mouse-autoselect-window. When the mouse
8294 moves, call note_mouse_highlight. If help_echo changed, call
8295 gen_help_event to produce help-echo message in the echo area.
8296 Call clear_mouse_face if mouse_face_hidden is set in the mouse
8299 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
8301 * lread.c (read1): Simplify slightly to avoid an overflow warning
8302 with GCC 4.7.0 on x86-64.
8304 2012-05-26 Eli Zaretskii <eliz@gnu.org>
8306 * bidi.c (bidi_mirror_char): Revert last change: an int is
8307 definitely wide enough here.
8309 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
8311 Fix integer width and related bugs (Bug#9874).

8322 (allocate_pseudovector):
8323 Use int, not EMACS_INT, where int is wide enough.
8324 (inhibit_garbage_collection, Fgarbage_collect):
8325 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

8343 (Foverlay_recenter, last_overlay_modification_hooks_used)
8344 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
8345 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8346 (validate_region): Omit unnecessary test for b <= e,
8347 since that's guaranteed by the previous test.
8348 (adjust_overlays_for_delete): Avoid pos + length overflow.
8349 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
8350 (report_overlay_modification):
8351 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
8352 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
8353 Omit pointer cast, which isn't needed anyway, and doesn't work
8354 after the EMACS_INT -> ptrdiff_t change.
8355 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
8356 * buffer.h: Adjust decls to match defn changes elsewhere.

8361 not int, to avoid needless 32-bit limit on 64-bit hosts.
8362 (exec_byte_code): Use tighter memory-full test, one that checks
8363 for alloca overflow. Don't compute the address of the object just
8364 before an array, as that's not portable. Use EMACS_INT, not
8365 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
8366 * callint.c (Fcall_interactively):
8367 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

8378 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
8379 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8380 (casify_object): Avoid integer overflow when overallocating buffer.
8381 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
8382 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
8383 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
8384 * category.h (CATEGORYP): Don't assume arg is nonnegative.
8385 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
8386 integers are now checked earlier. All uses replaced with XINT.
8388 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8389 For CCL_MapSingle, check that content and value are in int range.
8390 (ccl_driver, Fregister_code_conversion_map):
8391 Check that Vcode_version_map_vector is a vector.
8392 (resolve_symbol_ccl_program): Check that vector header is in range.
8393 Always copy the vector, so that we can check its contents reliably
8394 now rather than having to recheck each instruction as it's being
8395 executed. Check that vector words fit in 'int'.
8396 (ccl_get_compiled_code, Fregister_ccl_program)
8397 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
8398 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
8399 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
8400 contents are in range.
8401 (Fccl_execute_on_string): Check that status is in range.
8402 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
8403 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
8404 Accept and return EMACS_INT, not int, because callers can pass values

8410 (string_escape_byte8, Fget_byte):
8411 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8412 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
8413 avoid mishandling large integers.
8414 * character.h: Adjust decls to match defn changes elsewhere.

8423 (Fdefine_charset_internal): Check ranges here, more carefully.
8424 Don't rely on undefined behavior with signed left shift overflow.
8425 Don't assume unsigned int fits into fixnum, or that fixnum fits
8426 into unsigned int. Don't require max_code to be a valid fixnum;
8427 that's not true for gb10830 4-byte on a 32-bit host. Allow
8428 invalid_code to be a cons, for the same reason. Require code_offset
8429 to be a character. Avoid int overflow if max_char is close
8431 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
8432 this is intended anyway and avoids some undefined behavior.
8433 (load_charset_map): Pass unsigned, not int, as 2nd arg of
8434 INDEX_TO_CODE_POINT, as that's what it expects.
8435 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
8436 * charset.h (DECODE_CHAR): Return int, not unsigned;
8437 this is what was intended anyway, and it avoids undefined behavior.
8438 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
8439 integer-overflow issues.
8440 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
8441 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
8442 where the argument is EMACS_INT, and this behavior is not intended.
8443 * chartab.c (Fmake_char_table, Fset_char_table_range)
8444 (uniprop_get_decoder, uniprop_get_encoder):
8445 Don't assume fixnum fits in int.
8446 * cmds.c (move_point): New function, that does the gist of
8447 Fforward_char and Fbackward_char, but does so while checking
8448 for integer overflow more accurately.
8449 (Fforward_char, Fbackward_char): Use it.
8450 (Fforward_line, Fend_of_line, internal_self_insert)
8451 (internal_self_insert):
8452 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

8489 Don't access memory outside of the args array.
8490 (Fdefine_coding_system_internal): Check for charset-id overflow.

9154 define them any more.

9162 * s/ms-w32.h (DATA_START):
9163 Move here from removed file m/intel386.h.
9164 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.

9243 (report_error, report_error_1, make_hdr, copy_sym)
9244 (mark_x, adjust_lnnoptrs, unrelocate_symbols):

9250 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
9251 already have overlays loaded.
9252 (handle_single_display_spec): Before returning without displaying
9253 fringe bitmap, synchronize the bidi iterator with the main display
9254 iterator, by calling iterate_out_of_display_property.
9255 (iterate_out_of_display_property): Detect buffer iteration by
9256 testing that it->string is a Lisp string.
9257 (get_next_display_element): When the current object is exhausted,
9258 and there's something on it->stack, call set_iterator_to_next to
9259 proceed with what's on the stack, instead of returning zero.
9260 (set_iterator_to_next): If called at the end of a Lisp string,
9261 proceed to consider_string_end without incrementing string
9262 position. Don't increment display vector index past the end of
9263 the display vector. (Bug#11417)
9264 (pos_visible_p): Don't report a position visible when move_it_to
9265 stopped at the last line of window, which happens to be scanned
9266 backwards by the bidi iteration. (Bug#11464)
9268 2012-05-14 Eli Zaretskii <eliz@gnu.org>
9270 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
9271 and right-margin display specs even if the spec is invalid or we
9272 are on a TTY, and thus unable to display on the fringes.
9273 That's because the text with the property will not be displayed anyway,
9274 so we need to signal to the caller that this is a "replacing"
9275 display spec. This fixes display when the spec is invalid or we
9278 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
9280 * unexaix.c (make_hdr): Fix typo in prototype.
9281 This bug broke the build on AIX. Problem reported by Gilles Pion.

9285 * keyboard.c (kbd_buffer_get_event): Read special events also in

9313 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
9315 * xgselect.c (xg_select): Put maxfds+1 into a var.
9316 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
9318 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
9320 2012-05-10 Dave Abrahams <dave@boostpro.com>
9322 * filelock.c (syms_of_filelock): New boolean create-lockfiles.

9330 Initialize xd_registered_buses.
9332 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
9334 Untag more efficiently if USE_LSB_TAG.
9335 This is based on a proposal by YAMAMOTO Mitsuharu in
9336 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
9337 For an admittedly artificial (nth 8000 longlist) benchmark on
9338 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
9339 Emacs's overall text size by 1%.
9340 * lisp.h (XUNTAG): New macro.
9341 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)

9343 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
9344 * eval.c (Fautoload):
9345 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
9346 * frame.h (XFRAME): Use XUNTAG.
9348 Port recent dbusbind.c changes to 32-bit --with-wide-int.
9349 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
9350 Remove unportable assumptions about print widths of types like
9352 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
9353 intptr_t when converting between pointer and integer, to avoid GCC
9354 warnings about wrong width.
9356 2012-05-09 Eli Zaretskii <eliz@gnu.org>
9358 * w32proc.c (new_child): Force Windows to reserve only 64KB of
9359 stack for each reader_thread, instead of defaulting to 8MB
9360 determined by the linker. This avoids failures in creating
9361 subprocesses on Windows 7, see the discussion in this thread:
9362 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
9364 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
9366 Fix up display of the *Minibuf-0* buffer in the mini window.
9367 * keyboard.c (read_char): Don't clear the echo area if there's no
9369 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
9370 contents of *Minibuf-0*) if there's no message displayed in its stead.
9372 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
9374 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
9377 2012-05-06 Chong Yidong <cyd@gnu.org>
9379 * lisp.mk (lisp): Update.
9381 2012-05-05 Jim Meyering <meyering@redhat.com>
9383 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
9385 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
9387 * data.c (PUT_ERROR): New macro.
9388 (syms_of_data): Use it. Add new error type `user-error'.
9389 * undo.c (user_error): New function.
9390 (Fprimitive_undo): Use it.
9391 * print.c (print_error_message): Adjust print style for `user-error'.
9392 * keyboard.c (user_error): New function.
9393 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
9395 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
9397 Do not limit current-time-string to years 1000..9999.
9398 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
9399 (Fcurrent_time_string): Support any year that is supported by the
9400 underlying localtime representation. Don't use asctime, as it
9401 has undefined behavior for years outside the range -999..9999.
9403 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
9405 Fix race conditions involving setenv, gmtime, localtime, asctime.
9406 Without this fix, interrupts could mess up code that uses these
9407 nonreentrant functions, since setting TZ invalidates existing
9408 tm_zone or tzname values, and since most of these functions return
9409 pointers to static storage.
9410 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
9411 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
9412 Grow the critical sections to include not just invoking
9413 localtime/gmtime, but also accessing these functions' results
9414 including their tm_zone values if any, and any related TZ setting.
9415 (format_time_string): Last arg is now struct tm *, not struct tm **,
9416 so that the struct tm is saved in the critical section.
9417 All callers changed. Simplify allocation of initial buffer, partly
9418 motivated by the fact that memory allocation needs to be outside
9419 the critical section.
9421 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
9423 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
9424 with RESET_INTERVAL.
9426 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
9427 Remove duplicated buffer name initialization.
9429 2012-05-02 Jim Meyering <jim@meyering.net>
9431 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
9433 * xfns.c (x_window): Use xstrdup (Bug#11375).
9435 2012-05-02 Eli Zaretskii <eliz@gnu.org>
9437 * xdisp.c (pos_visible_p): If already at a newline from the
9438 display string before the 'while' loop, don't walk back the glyphs
9439 from it3.glyph_row. Solves assertion violation when the display
9440 string begins with a newline (egg.el). (Bug#11367)
9442 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
9444 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
9447 2012-05-01 Glenn Morris <rgm@gnu.org>
9449 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
9450 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
9451 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
9452 All were removed before 23.1.
9454 * dispnew.c: Remove HAVE_LIBNCURSES test;
9455 it is always true on relevant platforms.
9457 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
9458 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
9460 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
9462 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
9464 * .gdbinit (xpr): Remove checks for no longer existing misc types.
9465 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
9468 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
9470 Do not avoid creating empty evaporating overlays (Bug#9642).
9471 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
9472 That is, do not delete an evaporating overlay if it becomes
9473 empty after its bounds are adjusted to fit within its buffer.
9474 This fix caused other problems, and I'm reverting it until we get
9475 to the bottom of them.
9477 2012-04-27 Chong Yidong <cyd@gnu.org>
9479 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
9481 2012-04-27 Eli Zaretskii <eliz@gnu.org>
9483 * xdisp.c (pos_visible_p): If the window start position is beyond
9484 ZV, start the display from buffer beginning. Prevents assertion
9485 violation in init_iterator when the minibuffer window is scrolled
9488 * window.c (window_scroll_pixel_based): Likewise.
9490 2012-04-27 Chong Yidong <cyd@gnu.org>
9492 * keymap.c (where_is_internal): Doc fix (Bug#10872).
9494 2012-04-27 Glenn Morris <rgm@gnu.org>
9496 * fileio.c (Fcopy_file, Fset_file_selinux_context):
9497 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
9499 2012-04-27 Eli Zaretskii <eliz@gnu.org>
9501 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
9502 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
9504 2012-04-26 Eli Zaretskii <eliz@gnu.org>
9506 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
9507 display element, check also the underlying string or buffer
9508 character. (Bug#11341)
9510 * w32menu.c: Include w32heap.h.
9511 (add_menu_item): If the call to AppendMenuW (via
9512 unicode_append_menu) fails, disable Unicode menus only if we are
9513 running on Windows 9X/Me.
9515 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
9517 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
9518 (xgetint): Add missing shift for LSB tags.
9520 2012-04-24 Martin Rudalics <rudalics@gmx.at>
9522 * keyboard.c (read_char): Don't wipe echo area for select window
9523 events: These might get delayed via `mouse-autoselect-window'
9526 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
9528 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
9529 manipulation of :loaded-from data.
9531 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
9533 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
9534 now a cons (bug#11311).
9536 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
9538 Do not create empty overlays with the evaporate property (Bug#9642).
9539 * buffer.c (Fmove_overlay): Delete an evaporating overlay
9540 if it becomes empty after its bounds are adjusted to fit within
9541 its buffer. Without this fix, in a nonempty buffer (let ((o
9542 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
9543 yields an empty overlay that has the evaporate property, which is
9544 not supposed to happen.
9546 Fix minor GTK3 problems found by static checking.
9547 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
9548 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
9549 (struct _EmacsFixedClass, emacs_fixed_get_type):

9559 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
9561 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
9562 Problem reported by Juanma Barranquero for Windows -Wunused-function.
9564 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
9566 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
9567 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
9568 (__malloc_size_t, __malloc_ptrdiff_t):
9569 Remove. All uses removed, replaced by the definiens if needed,
9570 since we can assume C89 or better now.
9571 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
9572 (protect_malloc_state, align, get_contiguous_space)
9573 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)

9579 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
9580 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
9581 Define using prototypes, not old style.
9582 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
9583 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
9584 (align): Don't assume that signed integer overflow wraps around.
9585 Omit unused local var.
9586 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
9587 (_free_internal_nolock, memalign, mallochook, reallochook):

9646 * alloc.c: Handle unusual debugging option combinations.
9647 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
9648 since the two debugging options are incompatible.

9661 * sysdep.c [__FreeBSD__]: Minor cleanups.
9662 (list_system_processes, system_process_attributes) [__FreeBSD__]:
9663 Use Emacs indenting style more consistently. Avoid some casts.

9705 farther than the first row after the header line, if any.
9706 Don't consider the header-line row as "partially visible", even if
9707 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)

9750 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
9751 Remove one incorrect comment and fix another.

9762 (r_alloc_free) [REL_ALLOC]: Move decls from here ...
9763 * lisp.h (r_alloc, r_alloc_free, r_re_alloc, r_alloc_reset_variable)
9764 [REL_ALLOC]: ... to here, to check interface.
9765 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
9766 Remove decls. This fixes an "It stinks!".
9768 * alloc.c (which_symbols): Fix alignment issue / type clash.
9770 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
9772 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

9789 Remove definition of GC_MARK_STACK, since the default now works.
9790 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
9791 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
9792 no longer the default.
9793 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
9795 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
9797 * lread.c (lisp_file_lexically_bound_p):
9798 Fix hang at ";-*-\n" (bug#11238).
9800 2012-04-14 Eli Zaretskii <eliz@gnu.org>
9802 * xdisp.c (find_last_unchanged_at_beg_row): Don't consider a row
9803 "unchanged" if its end.pos is beyond ZV. (Bug#11199)
9805 2012-04-14 Jan Djärv <jan.h.d@swipnet.se>
9807 * nsterm.m (constrainFrameRect): Always constrain when there is only
9808 one screen (Bug#10962).
9810 2012-04-13 Ken Brown <kbrown@cornell.edu>
9812 * s/cygwin.h (PTY_OPEN): Don't try to close a bogus file descriptor.

9818 2012-04-11 Daniel Colascione <dancol@dancol.org>
9820 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
9821 against is gone. It's better to use vfork now so that when Cygwin
9822 gains a new, working vfork, we use it automatically (bug#10398).
9824 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
9826 * window.c (save_window_save): Obey window-point-insertion-type.

9832 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
9834 * alloc.c (lisp_align_malloc): Remove unneeded prototype.
9836 2012-04-10 Jason S. Cornez <jcornez@ravenpack.com> (tiny change)
9838 * keyboard.c: Override inhibit-quit after the third C-g (bug#6585).
9839 (force_quit_count): New var.
9840 (handle_interrupt): Use it.
9842 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
9844 * w32.c (w32_delayed_load): Record the full path of the library
9845 being loaded (bug#10424).
9847 2012-04-09 Glenn Morris <rgm@gnu.org>
9849 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
9850 not just in the obarray, before snarfing them. (Bug#11036)
9852 * Makefile.in ($(leimdir)/leim-list.el):
9853 Pass EMACS rather than BUILT_EMACS.
9855 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
9857 * process.c (make_process):
9858 * process.h: Add integer `gnutls_handshakes_tried' member to
9861 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.
9862 Add convenience `GNUTLS_LOG2i' macro.
9864 * gnutls.c (gnutls_log_function2i): Convenience log function.
9865 (emacs_gnutls_read): Use new log functions,
9866 `gnutls_handshakes_tried' process member, and
9867 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
9868 attempts per process (connection).
9870 2012-04-09 Chong Yidong <cyd@gnu.org>
9872 * eval.c (Fuser_variable_p, user_variable_p_eh)
9873 (lisp_indirect_variable): Functions deleted.
9874 (Fdefvar): Caller changed.
9876 * callint.c (Finteractive, Fcall_interactively):
9877 * minibuf.c (Fread_variable): Callers changed.
9879 2012-04-09 Eli Zaretskii <eliz@gnu.org>
9881 * xdisp.c (set_cursor_from_row): If the display string appears in
9882 the buffer at position that is closer to point than the position
9883 after the display string, display the cursor on the first glyph of
9884 the display string. Fixes cursor display when a 'display' text
9885 property immediately follows invisible text. (Bug#11094)
9887 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
9889 composite.c: use 'double' consistently
9890 * composite.c (get_composition_id): Use 'double' consistently
9891 instead of converting 'float' to 'double' and vice versa; this is
9892 easier to understand and avoids a GCC warning.
9894 2012-04-09 Glenn Morris <rgm@gnu.org>
9896 * Makefile.in: Generate leim-list with bootstrap-emacs, in
9897 preparation for dumping it with emacs. (Bug#4789)
9898 (leimdir): New variable.
9899 ($(leimdir)/leim-list.el): New rule.
9900 (emacs$(EXEEXT)): Depend on leim-list.el.
9902 * buffer.c (Qucs_set_table_for_input): Remove. (Bug#9821)
9903 (Fget_buffer_create): Don't call Qucs_set_table_for_input.
9904 (init_buffer_once, syms_of_buffer): Remove Qucs_set_table_for_input.
9906 2012-04-08 Andreas Schwab <schwab@linux-m68k.org>
9908 * lisp.h (struct Lisp_Symbol): Add explicit padding to ensure
9911 2012-04-07 Juanma Barranquero <lekktu@gmail.com>
9913 * xml.c (init_libxml2_functions) [WINDOWSNT]:
9914 Remove unused local variable.
9916 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
9918 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
9919 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
9920 (mark_memory): Mark Lisp_Objects only if pointers might hide in
9921 objects, as mark_maybe_pointer will catch them otherwise.
9922 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
9923 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
9925 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
9927 Fix typo that broke non-Windows builds.
9928 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.
9930 2012-04-07 Eli Zaretskii <eliz@gnu.org>
9932 Support building on MS-Windows with libxml2.
9934 * makefile.w32-in (OBJ2): Add xml.$(O).
9935 (GLOBAL_SOURCES): Add xml.c.
9936 ($(BLD)/xml.$(O)): New dependency list.
9938 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
9939 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
9940 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
9941 [!WINDOWSNT]: New macros.
9942 (init_libxml2_functions, libxml2_loaded_p): New functions.
9943 (parse_region): Call fn_xmlCheckVersion instead of using the macro
9944 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
9945 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
9946 Calls xmlCleanupParser only if libxml2 was loaded (or statically
9948 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
9949 Call init_libxml2_functions before calling libxml2 functions.
9950 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
9952 * emacs.c: Don't include libxml/parser.h.
9953 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
9954 xmlCleanupParser directly.
9956 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
9958 2012-04-07 Eli Zaretskii <eliz@gnu.org>
9960 * indent.c (Fvertical_motion): If there is a display string at
9961 point, use it.vpos to compute how many lines to backtrack after
9962 move_it_to point. (Bug#11133)
9964 2012-04-06 Eli Zaretskii <eliz@gnu.org>
9966 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
9967 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
9968 about subtle differences between FETCH_CHAR* and STRING_CHAR*
9969 macros related to unification of CJK characters. For the details,
9970 see the discussion following the message here:
9971 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
9973 2012-04-04 Chong Yidong <cyd@gnu.org>
9975 * keyboard.c (Vdelayed_warnings_list): Doc fix.
9977 2012-04-01 Eli Zaretskii <eliz@gnu.org>
9979 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
9980 instead of alloca. (Bug#11138)
9982 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
9984 * w32menu.c (is_simple_dialog): Properly check lisp types.
9987 2012-03-31 Eli Zaretskii <eliz@gnu.org>
9989 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
9990 position we get to after a call to move_it_to fails the
9991 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
9992 only if we wind up in a string from display property. (Bug#11063)
9994 * window.c (Fdelete_other_windows_internal): Invalidate the row
9995 and column information about mouse highlight, so that redisplay
9996 restores it after reallocating the glyph matrices. (Bug#7464)
9998 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
9999 string comes from a `display' text property, use the buffer
10000 position of that property as if we actually saw that position in
10002 (move_it_by_lines): Remove the assertion that
10003 "it->current_x == 0 && it->hpos == 0" which can be legitimately
10004 violated when there's a before-string at the beginning of a line.
10007 2012-03-30 Eli Zaretskii <eliz@gnu.org>
10009 * xdisp.c (append_space_for_newline): If the default face was
10010 remapped, use the remapped face for the appended newline.
10011 (extend_face_to_end_of_line): Use the remapped default face for
10012 extending the face to the end of the line.
10013 (display_line): Call extend_face_to_end_of_line when the default
10014 face was remapped. (Bug#11068)
10016 2012-03-29 Eli Zaretskii <eliz@gnu.org>
10018 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
10020 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
10022 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
10024 2012-03-27 Glenn Morris <rgm@gnu.org>
10026 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
10029 2012-03-26 Kenichi Handa <handa@m17n.org>
10031 * dispextern.h (struct glyph): Fix previous change. Change the
10032 bit length of glyphless.ch to 25 (Bug#11082).
10034 2012-03-26 Chong Yidong <cyd@gnu.org>
10036 * keyboard.c (Vselection_inhibit_update_commands): New variable.
10037 (command_loop_1): Use it; inhibit selection update for
10038 handle-select-window too (Bug#8996).
10040 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
10042 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
10044 2012-03-25 Kenichi Handa <handa@m17n.org>
10046 * dispextern.h (struct glyph): Change the bit length of
10047 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
10049 2012-03-24 Eli Zaretskii <eliz@gnu.org>
10051 * s/ms-w32.h (tzname): Include time.h before redirecting to
10052 _tzname. Fixes the MSVC build. (Bug#9960)
10054 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
10056 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
10059 * xterm.c (XTread_socket): Only modify handling_signal if
10060 !SYNC_INPUT. (Bug#11080)
10062 2012-03-23 Eli Zaretskii <eliz@gnu.org>
10064 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
10065 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
10066 when fetching a multibyte character consumes more bytes than
10067 CHAR_BYTES returns, due to unification of CJK characters in
10068 string_char. (Bug#11073)
10070 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
10072 * process.c (wait_reading_process_output): Handle pty disconnect
10073 by refraining from sending oneself a SIGCHLD (bug#10933).
10075 2012-03-22 Chong Yidong <cyd@gnu.org>
10077 * dispextern.h (struct it): New member string_from_prefix_prop_p.
10079 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
10080 Mark string as coming from a prefix property.
10081 (handle_face_prop): Use default face for prefix strings (Bug#4281).
10082 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
10084 2012-03-21 Chong Yidong <cyd@gnu.org>
10086 * xfaces.c (Vface_remapping_alist): Doc fix.
10088 2012-03-20 Eli Zaretskii <eliz@gnu.org>
10090 * w32proc.c (Fw32_set_console_codepage)
10091 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
10094 2012-03-20 Chong Yidong <cyd@gnu.org>
10096 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
10097 to reflect default non-nil value of redisplay-dont-pause.
10099 2012-03-19 Kenichi Handa <handa@m17n.org>
10101 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
10102 it fit in a valid range (Bug#11003).
10104 2012-03-18 Eli Zaretskii <eliz@gnu.org>
10106 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
10107 that is not from display property, accept the row as a "cursor
10108 row" if one of the string's character has a non-nil `cursor'
10109 property. Fixes cursor positioning when there are newlines in
10110 overlay strings, e.g. in icomplete.el. (Bug#11035)
10112 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
10114 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
10116 2012-03-12 Chong Yidong <cyd@gnu.org>
10118 * eval.c (inhibit_lisp_code): Rename from
10119 inhibit_window_configuration_change_hook; move from window.c.
10121 * xfns.c (unwind_create_frame_1, Fx_create_frame):
10122 * window.c (run_window_configuration_change_hook)
10123 (syms_of_window): Callers changed.
10125 2012-03-11 Chong Yidong <cyd@gnu.org>
10127 * keymap.c (Fkey_description): Doc fix (Bug#9700).
10129 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
10131 2012-03-10 Chong Yidong <cyd@gnu.org>
10133 * frame.c (other_visible_frames): Don't assume the selected frame
10134 is visible (Bug#10955).
10136 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
10138 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
10140 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
10142 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
10143 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
10146 2012-03-03 Glenn Morris <rgm@gnu.org>
10148 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
10150 2012-03-02 Eli Zaretskii <eliz@gnu.org>
10152 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
10153 position past the first glyph_row that ends at ZV. (Bug#10902)
10154 (redisplay_window, next_element_from_string): Fix typos in
10156 (redisplay_window): Pass to move_it_vertically the margin in
10157 pixels, not in screen lines.
10159 2012-03-02 Glenn Morris <rgm@gnu.org>
10161 * buffer.c (buffer-list-update-hook): Doc fix.
10163 2012-02-29 Eli Zaretskii <eliz@gnu.org>
10165 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
10166 push_it before setting up the iterator for the first overlay
10167 string, even if we have an empty string loaded.
10168 (next_overlay_string): If there's an empty string on the iterator
10169 stack, pop the stack. (Bug#10903)
10171 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
10173 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
10174 Suggested by Stefan Monnier in
10175 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
10176 * alloc.c (widen_to_Lisp_Object): New static function.
10177 (mark_memory): Also mark Lisp_Objects by fetching pointer words
10178 and widening them to Lisp_Objects. This would work even if
10179 USE_LSB_TAG is defined and wide integers are used, which might
10180 happen in a future version of Emacs.
10182 2012-02-25 Chong Yidong <cyd@gnu.org>
10184 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
10187 * xselect.c (Fx_selection_exists_p): Doc fix.
10188 (x_clipboard_manager_save_all): Print an informative message
10189 before saving to clipboard manager.
10191 2012-02-24 Chong Yidong <cyd@gnu.org>
10193 * keyboard.c (process_special_events): Handle all X selection
10194 requests in kbd_buffer, not just the next one (Bug#8869).
10196 2012-02-23 Chong Yidong <cyd@gnu.org>
10198 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
10199 call when setting menu-bar-lines and tool-bar-lines parameters.
10200 (unwind_create_frame_1): New helper function.
10202 * window.c (inhibit_window_configuration_change_hook): New var.
10203 (run_window_configuration_change_hook): Obey it.
10204 (syms_of_window): Initialize it.
10206 2012-02-22 Chong Yidong <cyd@gnu.org>
10208 * xterm.c (x_draw_image_relief): Add missing type check for
10209 Vtool_bar_button_margin (Bug#10743).
10211 2012-02-21 Chong Yidong <cyd@gnu.org>
10213 * fileio.c (Vfile_name_handler_alist): Doc fix.
10215 * buffer.c (Fget_file_buffer): Protect against invalid file
10216 handler return value.
10218 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
10220 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
10221 when computing $valmask.
10223 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
10224 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
10225 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
10226 It's useless in that case, and it can cause problems on hosts
10227 that allocate halves of EMACS_INT values separately.
10228 Reported by Dan Horák. Diagnosed by Andreas Schwab in
10229 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
10230 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
10231 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
10232 it avoids undefined behavior on hosts where shifting right by more
10233 than the word width has undefined behavior.
10235 2012-02-19 Chong Yidong <cyd@gnu.org>
10237 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
10238 (Funhandled_file_name_directory, Ffile_name_as_directory)
10239 (Fdirectory_file_name, Fexpand_file_name)
10240 (Fsubstitute_in_file_name): Protect against invalid file handler
10241 return values (Bug#10845).
10243 2012-02-18 Eli Zaretskii <eliz@gnu.org>
10245 * .gdbinit (pitx): Fix incorrect references to fields of the
10248 2012-02-17 Chong Yidong <cyd@gnu.org>
10250 * syntax.c (Fscan_lists): Doc fix (Bug#10833).
10252 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>
10254 * image.c (MAX_IMAGE_SIZE): Increase from 6.0 to 10.0; see
10255 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
10257 2012-02-15 Chong Yidong <cyd@gnu.org>
10259 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
10260 marked as special. Also, starting docstrings with * is obsolete.
10262 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
10264 * gnutls.c (emacs_gnutls_write): Fix last change.
10266 2012-02-13 Lars Ingebrigtsen <larsi@gnus.org>
10268 * gnutls.c (emacs_gnutls_write): Set errno appropriately for
10271 2012-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
10273 * keymap.c (Fsingle_key_description): Handle char ranges.
10275 2012-02-12 Chong Yidong <cyd@gnu.org>
10277 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
10278 as that creates a dangerous corner case.

10848 2011-11-30 Eli Zaretskii <eliz@gnu.org>
10850 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
10851 verifies glyph row's hash code--we have just reallocated the

11016 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
11017 is set, removing the need for VIRT_ADDRESS_VARIES.
11018 (PURE_P): Use a more-efficient implementation that needs just one

11025 consistency with the new puresize.h.
11026 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
11027 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

11033 (erase_phys_cursor, update_window_cursor, show_mouse_face)
11034 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
11035 behave as if the cursor position were at the window margin.
11037 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
11038 and the cursor position is out of bounds, behave as if the cursor
11039 position were at the window margin. (Bug#10075)
11041 2011-11-18 Chong Yidong <cyd@gnu.org>
11043 * window.c (Fwindow_combination_limit): Make first argument

11062 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
11064 * xdisp.c (row_hash): New function, body extracted from
11065 compute_line_metrics.
11066 (compute_line_metrics): Call row_hash, instead of computing the
11069 * dispnew.c (verify_row_hash): Call row_hash for computing the
11070 hash code of a row, instead of duplicating code from xdisp.c.
11072 * dispextern.h (row_hash): Add prototype.
11074 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
11076 * frame.c (delete_frame): Don't delete the terminal when the last

11130 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
11131 current_matrix and desired_matrix. (Bug#9990)
11132 (verify_row_hash) [XASSERTS]: New function.

11179 Avoid some portability problems by eschewing 'extern inline' functions.
11180 The trivial performance wins aren't worth the portability hassles; see
11181 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
11183 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

11232 This is also needed for porting to any host where GC_MARK_STACK is
11233 not GC_MAKE_GCPROS_NOOPS.
11234 (which_symbols): Use it.
11236 2011-11-07 Kenichi Handa <handa@m17n.org>

11249 * xmenu.c (cleanup_widget_value_tree): New function.
11250 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
11251 calling free_menubar_widget_value_tree directly (Bug#9830).
11253 2011-11-06 Paul Eggert <eggert@cs.ucla.edu>
11255 Fix some portability problems with 'inline'.
11256 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
11257 (window_box_width, window_box_left, window_box_left_offset)
11258 (window_box_right, window_box_right_offset): Declare extern.
11259 Otherwise, these inline functions do not conform to C99 and
11260 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
11261 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
11262 * intervals.c (adjust_intervals_for_insertion)
11263 (adjust_intervals_for_deletion): Now extern, because otherwise the
11264 extern inline functions 'offset_intervals' couldn't refer to it.
11265 (static_offset_intervals): Remove.
11266 (offset_intervals): Rewrite using the old contents of
11267 static_offset_intervals. The old version didn't conform to C99
11268 because an extern inline function contained a reference to an
11269 identifier with static linkage.
11271 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
11273 * keyboard.c (interrupt_signal): Don't call kill-emacs while in

11291 (Fwindow_vscroll): Doc fix.
11292 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
11293 argument, since it makes no sense to pass a live window and for
11294 consistency with window-child.

11335 official. Move initialization of image_cache_refcount and
11336 dpyinfo_refcount before calling init_frame_faces (Bug#9943).

11376 previous/next-single-property-change returns nil, treat that as
11377 the beginning or the end of the buffer. (Bug#9955)
11379 2011-11-04 Jan Djärv <jan.h.d@swipnet.se>
11381 * gtkutil.c (xg_make_tool_item): Add callbacks if one of wimage or

11504 (w32font_open_internal, compute_metrics):
11505 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
11506 instead of calling the "wide" APIs directly.
11508 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
11510 * w32.h (syms_of_w32font): Add prototype.
11512 2011-10-27 Juanma Barranquero <lekktu@gmail.com>

11519 2011-10-27 Chong Yidong <cyd@gnu.org>
11521 * process.c (make_process): Set gnutls_state to NULL.
11523 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
11524 non-NULL, regardless of GNUTLS_INITSTAGE.

11573 (bidi_resolve_weak): Don't enter the expensive loop if the current
11574 position is before next_en_pos. Record the bidi type of the first
11575 non-ET, non-BN character we find, in addition to its position.
11576 (bidi_level_of_next_char): Invalidate next_en_type when
11577 next_en_pos is over-stepped.
11579 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
11581 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
11582 * editfns.c: Rewrite current-time-zone so that it invokes
11583 the equivalent of (format-time-string "%Z") to get the time zone name.
11584 This fixes a bug when the time zone name contains characters that
11585 need converting from the system time locale to Emacs internal format.
11586 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
11587 that patch fixed format-time-string to do the conversion, but
11588 I forgot to fix current-time-zone.
11589 (format_time_string): New function, containing most of
11590 what Fformat_time_string used to contain.
11591 (Fformat_time_string): Rewrite in terms of format_time_string.
11592 This doesn't change this function's behavior.
11593 (current-time-zone): Rewrite to use format_time_string.
11594 This fixes the bug reported by Michael Schierl in
11595 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
11596 Jason Rumney's 2007-06-07 change worked around this bug, but
11598 * systime.h (tzname, timezone): Remove no-longer-used declarations.
11600 2011-10-19 Eli Zaretskii <eliz@gnu.org>
11602 * xdisp.c (start_display): If the character at POS is displayed
11603 via a display vector, reset IT->current.dpvec_index to zero.
11604 (try_window_reusing_current_matrix): If a line ends in a display
11605 vector or the next line starts in a display vector, continue
11606 redrawing the window even though the character position of
11607 start_row was reached.
11610 2011-10-18 Chong Yidong <cyd@gnu.org>
11612 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
11613 with nobreak-char-display too.
11615 2011-10-18 Eli Zaretskii <eliz@gnu.org>
11617 Fix part 3 of bug#9771.
11618 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
11619 (bidi_resolve_neutral): Don't enter the expensive loop looking for
11620 non-neutral characters if the current character is a paragraph
11621 separator (a.k.a. Newline). This avoids running the same
11622 expensive loop twice, once when we consume the preceding newline
11623 and the other time when the line actually needs to be displayed.
11624 Avoid the loop when we see neutrals on the base embedding level
11625 following a character whose directionality is the same as the
11626 paragraph's. This avoids running the expensive loop when a line
11627 ends in a long sequence of neutrals, like control characters.
11628 Add assertion against STRONG_AL type. Slightly rearrange code
11629 that determines the type of a neutral given the first non-neutral
11631 (bidi_level_of_next_char): Set next_en_pos to zero when
11632 invalidating its info.
11634 2011-10-17 Eli Zaretskii <eliz@gnu.org>
11636 * xdisp.c (push_display_prop): Determine whether to record string
11637 or buffer position by IT->string, not by IT->method. Allow
11638 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
11639 (move_it_vertically_backward): Don't look for character position
11640 immediately after the newline when in a continuation line.
11643 2011-10-15 Martin Rudalics <rudalics@gmx.at>
11645 * window.c (coordinates_in_window): Rewrite and delabelize
11646 vertical border check. (Bug#5357) (Bug#9618)
11648 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
11650 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
11651 errors in XSetWindowBorder (bug#9310).
11653 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
11655 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
11656 avoid crash when xmalloc overrun checking is enabled.
11658 2011-10-13 Eli Zaretskii <eliz@gnu.org>
11660 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
11661 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
11662 cursor motion with <left> and <right> arrow keys.
11664 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
11665 some callers set that themselves.
11667 2011-10-12 Eli Zaretskii <eliz@gnu.org>
11669 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
11670 display string and the previous row comes from the same string and
11671 is empty. (Bug#9739) (Bug#9738)
11673 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
11675 * doc.c (get_doc_string): Encode file name (bug#9735).
11677 2011-10-12 Eli Zaretskii <eliz@gnu.org>
11679 * bidi.c (bidi_level_of_next_char):
11680 * xdisp.c (get_visually_first_element): Remove old incorrect
11681 comments regarding the Unicode Line Separator character.
11683 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
11685 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
11687 * alloc.c (Fgc_status): Do not access beyond zombies array
11688 boundary if nzombies > MAX_ZOMBIES.
11689 * alloc.c (dump_zombies): Add missing format specifier.
11691 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
11693 * xdisp.c (set_cursor_from_row): Simplify conditionals,
11694 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
11696 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
11697 Some packages use them to denote characters with modifiers.
11699 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
11701 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
11702 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
11703 matching a pp-number. Rename parameter var to var1.
11705 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
11707 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
11709 2011-10-08 Glenn Morris <rgm@gnu.org>
11711 * callint.c (Fcall_interactively): Give a more explicit error for the
11712 'c' case with a non-character input. (Bug#8479)
11714 2011-10-08 Eli Zaretskii <eliz@gnu.org>
11716 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
11718 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
11719 lines that are hscrolled on the left.
11721 * dispnew.c (buffer_posn_from_coords): Account for a possible
11722 presence of header-line. (Bug#4426)
11724 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
11726 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
11727 Don't advertise functionality which we discourage or doesn't work.
11729 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
11731 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
11732 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
11733 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
11734 this makes Emacs dump core during garbage collection on rare
11735 occasions. sizeof is obviously inferior to offsetof here, so
11736 stick with offsetof.
11737 (GC_POINTER_ALIGNMENT): New macro.
11738 (mark_memory): Omit 3rd (offset) arg; caller changed.
11739 Don't assume EMACS_INT alignment is the same as pointer alignment.
11741 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
11743 * keyboard.c (read_key_sequence_remapped): New var.
11744 (read_key_sequence): Compute remapping in the right buffer.
11745 (command_loop_1): Use read_key_sequence's remapping directly.
11747 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
11749 * dired.c (file_name_completion): Don't expand file name.
11750 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
11751 before checking file name handler.
11753 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
11754 they've been requested explicitly (bug#9591).
11756 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
11758 * keymap.c (Fsingle_key_description): Use make_specified_string
11759 instead of build_string to build string from push_key_description.
11762 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
11764 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
11765 This fixes a Y2038 bug on 64-bit hosts.
11766 * buffer.c (reset_buffer):
11767 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
11768 (Fclear_buffer_auto_save_failure):
11769 Use 0, not -1, to represent an unset failure time, since time_t
11770 might not be signed.
11772 Remove dependency on glibc malloc internals.
11773 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11774 Move back here from lisp.h, but with their new implementations.
11775 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
11776 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
11777 * charset.c (charset_table_init): New static var.
11778 (syms_of_charset): Use it instead of xmalloc. This removes a
11779 dependency on glibc malloc internals. See Eli Zaretskii's comment in
11780 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
11781 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11782 Move back to alloc.c.
11783 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
11784 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
11786 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
11788 * nsterm.m (windowDidResize): Call x_set_window_size only when
11789 ns_in_resize is true. Otherwise set pixelwidth/height and
11790 call change_frame_size (Bug#9628).
11792 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
11794 Port --enable-checking=all to Fedora 14 x86-64.
11795 * charset.c (syms_of_charset): Also account for glibc malloc's
11796 internal overhead when calculating the initial malloc maximum.
11798 Port --enable-checking=all to Fedora 14 x86.
11799 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11801 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
11802 (overrun_check_realloc, overrun_check_free):
11803 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
11804 That way, xmalloc returns a properly-aligned pointer even if
11805 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
11806 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
11807 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
11808 into account when calculating the initial malloc maximum.
11809 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11810 Move here from alloc.c, so that charset.c can use it too.
11811 Properly align; the old code wasn't right for common 32-bit hosts
11812 when configured with --enable-checking=all.
11813 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
11814 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
11816 2011-09-29 Eli Zaretskii <eliz@gnu.org>
11818 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
11821 2011-09-28 Eli Zaretskii <eliz@gnu.org>
11823 * xdisp.c (compute_display_string_end): If there's no display
11824 string at CHARPOS, return -1.
11826 * bidi.c (bidi_fetch_char): When compute_display_string_end
11827 returns a negative value, treat the character as a normal
11828 character not covered by a display string. (Bug#9624)
11830 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
11832 * lread.c (Fread_from_string): Fix typo in docstring.
11834 2011-09-27 Eli Zaretskii <eliz@gnu.org>
11836 * xdisp.c (handle_invisible_prop): If invisible text ends on a
11837 newline, reseat the iterator instead of bidi-iterating there one
11838 character at a time. (Bug#9610)
11839 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
11840 TO_CHARPOS if the bidi iterator is at base embedding level.
11842 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
11844 * lread.c (readevalloop): Use correct code for NBSP.
11845 (read1): Likewise. (Bug#9608)
11847 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
11849 * dbusbind.c (Fdbus_register_signal): When service is not
11850 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
11852 2011-09-25 Glenn Morris <rgm@gnu.org>
11854 * buffer.c (truncate-lines): Doc fix.
11856 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
11858 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
11859 (Fset_window_next_buffers): Doc fix.
11861 2011-09-24 Glenn Morris <rgm@gnu.org>
11863 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
11865 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
11867 Fix minor problems found by static checking.
11868 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
11869 * indent.c (Fvertical_motion): Fix == vs = typo.
11871 2011-09-24 Eli Zaretskii <eliz@gnu.org>
11873 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
11874 Default value is now t. Doc fix.
11876 * indent.c (Fvertical_motion): Compute and apply the overshoot
11877 logic when moving up, not only when moving down. Fix the
11878 confusing name and values of the it_overshoot_expected variable;
11879 logic changes accordingly. (Bug#9254) (Bug#9549)
11881 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
11882 CHARPOS is covered by a display string which includes newlines.
11883 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
11884 is covered by a display string with embedded newlines.
11886 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
11888 * dbusbind.c (Fdbus_register_signal): Add match rule to
11889 Vdbus_registered_objects_table. (Bug#9581)
11890 (Fdbus_register_method, Vdbus_registered_objects_table):
11893 2011-09-24 Jim Meyering <meyering@redhat.com>
11895 do not ignore write error for any output size
11896 The previous change was incomplete.
11897 While it makes emacs --batch detect the vast majority of stdout
11898 write failures, errors were still ignored whenever the output size is
11899 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
11900 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
11901 && echo FAIL: ignored write error
11902 FAIL: ignored write error
11903 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
11904 && echo FAIL: ignored write error
11905 FAIL: ignored write error
11906 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
11908 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
11910 * emacs.c (Fkill_emacs): In noninteractive mode exit
11911 non-successfully if a write error occurred on stdout. (Bug#9574)
11913 2011-09-21 Eli Zaretskii <eliz@gnu.org>
11915 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
11918 * dispextern.h (struct it): Update the comment documenting what
11921 2011-09-20 Eli Zaretskii <eliz@gnu.org>
11923 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
11924 a display string, extend search for cursor position to end of row.
11925 (find_row_edges): If the row ends in a newline from a display
11926 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
11927 Handle the case of a display string with multiple newlines.
11928 (Fcurrent_bidi_paragraph_direction): Fix search for previous
11929 non-empty line. Fixes confusing cursor motion with arrow keys at
11930 the beginning of a line that starts with whitespace.
11932 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
11934 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
11937 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
11939 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
11940 boolean (Bug#9154).
11942 2011-09-18 Eli Zaretskii <eliz@gnu.org>
11944 * xdisp.c (display_line): Record maximum and minimum buffer
11945 positions even if no glyphs were produced (e.g., by a zero-width
11946 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
11947 buffer positions that will be removed from the glyph row because
11949 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
11950 column is beyond frame width: don't subtract 1 "pixel" when
11951 computing width of the stretch.
11952 (reseat_at_next_visible_line_start): Undo the change made on
11953 2011-09-17 that saved paragraph information and restored it after
11954 the call to `reseat'. (Bug#9545)
11956 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11958 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
11959 and turn window cursor on if cleared (Bug#9415).
11961 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
11963 * search.c (boyer_moore): Take unibyte characters from pattern
11964 literally. (Bug#9458)
11966 2011-09-18 Eli Zaretskii <eliz@gnu.org>
11968 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
11970 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
11972 Fix minor problem found by static checking.
11973 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
11974 initialized, to pacify gcc -Wuninitialized.
11976 * fileio.c: Report proper errno when syscall falls.
11977 (Finsert_file_contents): Save and restore errno,
11978 so that report_file_error outputs the correct diagnostic.
11979 (Fwrite_region) [CLASH_DETECTION]: Likewise.
11981 2011-09-18 Eli Zaretskii <eliz@gnu.org>
11983 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
11985 2011-09-17 Eli Zaretskii <eliz@gnu.org>
11987 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
11988 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
11990 2011-09-17 Eli Zaretskii <eliz@gnu.org>
11992 * xdisp.c (reseat_at_next_visible_line_start): Keep information
11993 about the current paragraph and restore it after the call to reseat.
11995 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
11996 (bidi_find_paragraph_start): Search back for paragraph beginning
11997 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
11998 (bidi_move_to_visually_next): Only trigger paragraph-related
11999 computations when the last character is a newline or at EOB, not
12000 just any NEUTRAL_B. (Bug#9470)
12002 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
12003 truncated lines if point is covered by a display string. (Bug#9524)
12005 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
12007 * xselect.c: Relax test for outgoing X longs (Bug#9498).
12008 (cons_to_x_long): New function.
12009 (lisp_data_to_selection_data): Use it. Correct the test for
12010 short-versus-long data; it was negated. Break out of vector
12011 loop, for efficiency, when a long datum is discovered.
12013 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
12015 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
12017 2011-09-16 Eli Zaretskii <eliz@gnu.org>
12019 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
12020 GCC PR/17406) by declaring this function with external scope.
12022 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
12024 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
12025 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
12027 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
12029 * editfns.c (Fformat): Correctly handle text properties on "%%".
12031 2011-09-15 Eli Zaretskii <eliz@gnu.org>
12033 * xterm.c (x_draw_composite_glyph_string_foreground):
12034 * w32term.c (x_draw_composite_glyph_string_foreground):
12035 * term.c (encode_terminal_code):
12036 * composite.c (composition_update_it, get_composition_id):
12037 * xdisp.c (get_next_display_element)
12038 (fill_composite_glyph_string): Add comments about special meaning
12039 of TAB characters in a composition.
12041 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
12043 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
12044 This occurs when processing a multibyte format.
12045 Problem reported by Wolfgang Jenker.
12047 2011-09-15 Johan Bockgård <bojohan@gnu.org>
12049 * xdisp.c (try_cursor_movement): Only check for exact match if
12050 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
12052 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
12054 Remove unused external symbols.
12055 * dispextern.h (calc_pixel_width_or_height): Remove decl.
12056 * xdisp.c (calc_pixel_width_or_height): Now static.
12057 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
12058 * indent.c (check_display_width):
12059 * w32term.c: Fix comment to match code.
12060 * xterm.c, xterm.h (x_catching_errors): Remove.
12062 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
12064 * xselect.c: Use signed conversions more consistently (Bug#9498).
12065 (selection_data_to_lisp_data): Assume incoming selection data are
12066 signed integers, not unsigned. This is to be consistent with
12067 outgoing selection data, which was modified to use signed integers
12068 in as part of the fix to Bug#9196 in response to Jan D.'s comment
12069 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
12070 expects long, not unsigned long.
12072 2011-09-14 Eli Zaretskii <eliz@gnu.org>
12074 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
12075 computation of loop end. Reported by Johan Bockgård
12078 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
12080 * frame.c (Fother_visible_frames_p): Function deleted.
12082 2011-09-12 Eli Zaretskii <eliz@gnu.org>
12084 * indent.c (compute_motion): Process display vector front to back
12085 rather than the other way around. (Bug#2496)
12087 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
12089 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
12091 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
12093 * minibuf.c (Fread_from_minibuffer): Doc fix.
12095 2011-09-11 Eli Zaretskii <eliz@gnu.org>
12097 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
12098 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
12100 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
12102 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
12103 value for non-existent files.
12105 2011-09-11 Eli Zaretskii <eliz@gnu.org>
12107 * fileio.c (Finsert_file_contents): If the file cannot be opened,
12108 set its "size" to -1. This will set the modtime_size field of
12109 the corresponding buffer to -1, which is what
12110 verify-visited-file-modtime expects for files that do not exist.
12113 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
12115 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
12117 * lisp.h: ... from here. push_key_description is no longer
12118 defined in keyboard.c, so its declaration should not be in
12119 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
12120 logically belongs with push_key_description.
12122 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
12124 * buffer.h: Include <sys/types.h> instead of <time.h>.
12125 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
12126 Problem reported by Herbert J. Skuhra.

12130 * xml.c (parse_region): Make the parsing work for
12131 non-comment-starting XML files again (bug#9144).
12133 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
12135 * image.c (gif_load): Fix calculation of bottom and right corner.
12138 2011-09-10 Eli Zaretskii <eliz@gnu.org>
12140 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
12141 redisplay in small windows.
12143 2011-09-09 Eli Zaretskii <eliz@gnu.org>
12145 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
12147 2011-09-08 Martin Rudalics <rudalics@gmx.at>
12149 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
12150 Operate on live windows only.
12152 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
12154 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
12156 2011-09-07 Eli Zaretskii <eliz@gnu.org>
12158 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
12159 only under bidi iteration.
12161 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
12163 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
12165 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
12167 isnan: Fix porting problem to Solaris 10 with bundled gcc.
12168 Without this fix, the command to link temacs failed due to an
12169 undefined symbol __builtin_isnan. This is because
12170 /usr/include/iso/math_c99.h #defines isnan(x) to
12171 __builtin_isnan(x), but the bundled gcc, which identifies itself
12172 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
12174 * floatfns.c (isnan): #undef, and then #define to a clone of
12176 (Fisnan): Always define, since it's always available now.
12177 (syms_of_floatfns): Always define isnan at the Lisp level.
12179 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
12181 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
12183 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
12185 * fileio.c: Fix bugs with large file offsets (Bug#9428).
12186 The previous code assumed that file offsets (off_t values) fit in
12187 EMACS_INT variables, which is not true on typical 32-bit hosts.
12188 The code messed up by falsely reporting buffer overflow in cases
12189 such as (insert-file-contents "big" nil 1 2) into an empty buffer
12190 when "big" contains more than 2**29 bytes, even though this
12191 inserts just one byte and does not overflow the buffer.
12192 (Finsert_file_contents): Store file offsets as off_t
12193 values, not as EMACS_INT values. Check for overflow when
12194 converting between EMACS_INT and off_t. When checking for
12195 buffer overflow or for overlap, take the offsets into account.
12196 Don't use EMACS_INT for small values where int suffices.
12197 When checking for overlap, fix a typo: ZV was used where
12198 ZV_BYTE was intended.
12199 (Fwrite_region): Don't assume off_t fits into 'long'.
12200 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
12202 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
12204 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
12206 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
12208 sprintf-related integer and memory overflow issues (Bug#9412).
12210 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
12211 (esprintf, exprintf, evxprintf): New functions.
12212 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
12213 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
12214 (modify_event_symbol): Do not assume that the length of
12215 name_alist_or_stem is safe to alloca and fits in int.
12216 (Fexecute_extended_command): Likewise for function name and binding.
12217 (Frecursion_depth): Wrap around reliably on integer overflow.
12218 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
12219 since some callers pass EMACS_INT values.
12220 (Fsingle_key_description): Don't crash if symbol name contains more
12221 than MAX_ALLOCA bytes.
12222 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
12223 (get_minibuffer): Arg is now EMACS_INT, not int.
12224 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
12225 (esprintf, exprintf, evxprintf): New decls.
12226 * window.h (command_loop_level, minibuf_level): Reflect API changes.
12228 * dbusbind.c (signature_cat): New function.
12229 (xd_signature, Fdbus_register_signal):
12230 Do not overrun buffer; instead, report string overflow.
12232 * dispnew.c (add_window_display_history): Don't overrun buffer.
12233 Truncate instead; this is OK since it's just a log.
12235 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
12236 even if the time zone offset is outlandishly large.
12237 Don't mishandle offset == INT_MIN.
12239 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
12240 when creating daemon; the previous buffer-overflow check was incorrect.
12242 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
12243 which has the guts of the old verror function.
12245 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
12246 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
12248 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
12249 (font_unparse_xlfd): Don't blindly alloca long strings.
12250 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
12251 fits in int, when using sprintf. Use single snprintf to count
12252 length of string rather than counting it via multiple sprintfs;
12253 that's simpler and more reliable.
12254 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
12255 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
12256 sprintf, in case result does not fit in int.
12258 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
12259 (fontset_from_font): Print it.
12261 * frame.c (tty_frame_count): Now printmax_t, not int.
12262 (make_terminal_frame, set_term_frame_name): Print it.
12263 (x_report_frame_params): In X, window IDs are unsigned long,
12264 not signed long, so print them as unsigned.
12265 (validate_x_resource_name): Check for implausibly long names,
12266 and don't assume name length fits in 'int'.
12267 (x_get_resource_string): Don't blindly alloca invocation name;
12268 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
12271 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
12272 (xg_check_special_colors, xg_set_geometry):
12273 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
12275 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
12276 Use esprintf, not sprintf, in case result does not fit in int.
12278 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
12279 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
12280 it as a large positive number.
12281 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
12282 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
12284 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
12285 in case result does not fit in int.
12287 * print.c (float_to_string): Detect width overflow more reliably.
12288 (print_object): Make sprintf buffer a bit bigger, to avoid potential
12289 buffer overrun. Don't assume list length fits in 'int'. Treat
12290 print length of 0 as 0, not as infinity; to be consistent with other
12291 uses of print length in this function. Don't overflow print length
12292 index. Don't assume hash table size fits in 'long', or that
12293 vectorlike size fits in 'unsigned long'.
12295 * process.c (make_process): Use printmax_t, not int, to format
12296 process-name gensyms.
12298 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
12300 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
12301 to avoid potential buffer overrun.
12303 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
12304 if X resource line is longer than 512 bytes.
12306 * xfns.c (x_window): Make sprintf buffer a bit bigger
12307 to avoid potential buffer overrun.
12309 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
12311 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
12313 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
12315 Integer overflow fixes for scrolling, etc.
12316 Without these, Emacs silently mishandles large integers sometimes.
12317 For example, "C-u 4294967297 M-x recenter" was treated as if
12318 it were "C-u 1 M-x recenter" on a typical 64-bit host.
12320 * xdisp.c (try_window_id): Check Emacs fixnum range before
12321 converting to 'int'.
12323 * window.c (window_scroll_line_based, Frecenter):
12324 Check that an Emacs fixnum is in range before assigning it to 'int'.
12325 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
12326 values converted from Emacs fixnums.
12327 (Frecenter): Don't wrap around a line count if it is out of 'int'
12328 range; instead, treat it as an extreme value.
12329 (Fset_window_configuration, compare_window_configurations):
12330 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
12332 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
12333 that can exceed INT_MAX. Check that EMACS_INT value is in range
12334 before assigning it to the (possibly-narrower) index.
12335 (match_limit): Don't assume that a fixnum can fit in 'int'.
12337 * print.c (print_object): Use ptrdiff_t, not int, for index that can
12340 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
12341 (Fvertical_motion): Don't wrap around LINES values that don't fit
12342 in 'int'. Instead, treat them as extreme values. This is good
12343 enough for windows, which can't have more than INT_MAX lines anyway.
12345 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
12347 * Require libxml/parser.h to avoid compilation warning.
12349 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
12351 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
12352 since this reportedly can destroy thread storage.
12354 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
12356 * syntax.c (find_defun_start): Update all cache variables if
12357 exiting early (Bug#9401).
12359 2011-08-30 Eli Zaretskii <eliz@gnu.org>
12361 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
12363 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
12364 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
12365 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
12367 * term.c (tty_append_glyph): New function.
12368 (produce_stretch_glyph): Static function and its prototype deleted.
12370 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
12373 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
12375 * image.c (parse_image_spec): Check for nonnegative, not for positive,
12376 when checking :margin (Bug#9390).
12377 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
12378 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
12379 so that the name doesn't mislead. All uses changed.
12381 2011-08-28 Johan Bockgård <bojohan@gnu.org>
12383 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
12386 2011-08-27 Eli Zaretskii <eliz@gnu.org>
12388 * xdisp.c (move_it_to): Don't bail out early when reaching
12389 position beyond to_charpos, if we are scanning backwards.
12390 (move_it_vertically_backward): When DY == 0, make sure we get to
12391 the first character in the line after the newline.
12393 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
12395 * ccl.c: Improve and simplify overflow checking (Bug#9196).
12396 (ccl_driver): Do not generate an out-of-range pointer.
12397 (Fccl_execute_on_string): Remove unnecessary check for
12398 integer overflow, noted by Stefan Monnier in
12399 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
12400 Remove a FIXME that didn't need fixing.
12401 Simplify the newly-introduced buffer reallocation code.
12403 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
12405 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
12407 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
12409 Integer and memory overflow issues (Bug#9196).
12411 * doc.c (get_doc_string): Rework so that
12412 get_doc_string_buffer_size is the actual buffer size, rather than
12413 being 1 less than the actual buffer size; this makes xpalloc more
12416 * image.c (x_allocate_bitmap_record, cache_image):
12417 * xselect.c (Fx_register_dnd_atom):
12418 Simplify previous changes by using xpalloc.
12420 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
12421 since either will do and ptrdiff_t is convenient with xpalloc.
12423 * charset.c (charset_table_size)
12424 (struct charset_sort_data.priority): Now ptrdiff_t.
12425 (charset_compare): Don't overflow if priorities differ greatly.
12426 (Fsort_charsets): Don't assume list length fits in int.
12427 Check for size-calculation overflow when allocating sort data.
12428 (syms_of_charset): Allocate an initial charset table that is
12429 just under 64 KiB, to avoid problems with glibc malloc and mmap.
12431 * cmds.c (internal_self_insert): Check for size-calculation overflow.
12433 * composite.h (struct composition.glyph_len): Now int, not unsigned.
12434 The actual value is always <= INT_MAX, and leaving it unsigned made
12435 overflow checking harder.
12437 * dispextern.h (struct glyph_matrix.rows_allocated)
12438 (struct face_cache.size): Now ptrdiff_t, for convenience in use
12439 with xpalloc. The values are still always <= INT_MAX.
12441 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
12443 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
12444 (SAFE_NALLOCA): New macro.
12446 * region-cache.c (struct boundary.pos, find_cache_boundary)
12447 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
12448 (set_cache_region, invalidate_region_cache)
12449 (revalidate_region_cache, know_region_cache, region_cache_forward)
12450 (region_cache_backward, pp_cache):
12451 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
12452 so that ptrdiff_t * can be passed to xpalloc.
12453 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
12454 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
12455 (pp_cache): Don't assume cache_len fits in int.
12456 * region-cache.h: Adjust extern decls to match.
12458 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
12459 EMACS_INT, since either will do, for xpalloc.
12461 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
12462 (xnmalloc, xnrealloc, xpalloc): New functions.
12464 * bidi.c (bidi_shelve_header_size): New constant.
12465 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
12466 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
12468 * bidi.c (bidi_cache_shrink):
12469 * buffer.c (overlays_at, overlays_in, record_overlay_string)
12471 Don't update size of array until after memory allocation succeeds,
12472 because xmalloc/xrealloc may not return.
12473 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
12474 now that we have proper integer overflow checking.
12475 (record_overlay_string, overlay_strings): Catch overflows when
12476 calculating size of overlay_str_buf.
12478 * callproc.c (Fcall_process): Check for size overflow when
12479 calculating size of args2.
12480 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
12481 Normally we prefer signed values, but sticking with ptrdiff_t would
12482 require adding more-complicated checks.
12484 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
12485 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
12486 Redo buffer-overflow calculations to avoid integer overflow.
12487 Add a FIXME comment where memory seems to be over-allocated.
12489 * character.c (Fstring): Check for size-calculation overflow.
12491 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
12492 unnecessary integer overflow. Check for size overflow.
12493 (encode_coding_object): Don't update size until xmalloc succeeds.
12495 * composite.c (get_composition_id): Check for overflow in glyph
12496 length calculations.
12498 Integer and memory overflow fixes for display code.
12499 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
12500 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
12501 (scrolling_window): Check for overflow in size calculations.
12502 (line_draw_cost, realloc_glyph_pool, add_row_entry):
12503 Don't assume glyph table len fits in int.
12504 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
12505 (row_table_size): Now ptrdiff_t, not int.
12506 (scrolling_window): Avoid overflow in size calculations.
12507 Don't update size until allocation succeeds.
12508 * fns.c (concat): Check for overflow in size calculations.
12509 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
12510 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
12511 (NEXT_ALMOST_PRIME_LIMIT): New constant.
12513 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
12514 (get_doc_string): Check for size calculation overflow.
12515 Don't update size until allocation succeeds.
12516 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
12517 EMACS_INT, where ptrdiff_t will do.
12518 (Fsubstitute_command_keys): Check for string overflow.
12520 * editfns.c (set_time_zone_rule): Don't assume environment length
12522 (message_length): Now ptrdiff_t, not int.
12523 (Fmessage_box): Don't update size until allocation succeeds.
12524 Don't assume message length fits in int.
12525 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
12527 * emacs.c (main): Do not reallocate argv, since there is a null at
12528 the end that can be overwritten, and this way there's no need to
12529 worry about size-calculation overflow.
12530 (sort_args): Check for size-calculation overflow.
12532 * eval.c (init_eval_once, grow_specpdl): Don't update size until
12534 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
12536 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
12537 (x_set_scroll_bar_width, x_figure_window_size):
12538 Check for integer overflow.
12539 (x_set_alpha): Do not assume XINT fits in int.
12541 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
12542 This is for the members text_lines, text_cols, total_lines, total_cols,
12543 where the system imposes an 'int' limit.
12545 * fringe.c (Fdefine_fringe_bitmap):
12546 Don't update size until alloc works.
12548 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
12549 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
12551 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
12552 Check for size-calculation overflow.
12553 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
12554 do, as we prefer signed integers.
12555 (id_to_widget.max_size, id_to_widget.used)
12556 (xg_store_widget_in_map, xg_remove_widget_from_map)
12557 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
12558 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
12559 Use and return ptrdiff_t, not int.
12560 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
12561 * gtkutil.h: Change prototypes to match the above.
12563 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
12564 are duplicate now that they've been promoted to lisp.h.
12565 (x_allocate_bitmap_record, x_alloc_image_color)
12566 (make_image_cache, cache_image, xpm_load):
12567 Don't update size until alloc is done.
12568 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
12570 Check for size calculation overflow.
12571 (ct_colors_allocated_max): New constant.
12572 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid
12575 * keyboard.c (read_char, menu_bar_items, tool_bar_items)
12576 (read_char_x_menu_prompt, read_char_minibuf_menu_width)

12610 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
12611 for command line length. Do not attempt to address one before the
12612 beginning of an array, as that's not portable.
12614 * term.c (max_frame_lines): Remove; unused.

12644 memory exhaustion (the usual treatment), rather than aborting.
12646 * xfns.c (x_encode_text, x_set_name_internal)
12647 (Fx_change_window_property): Use ptrdiff_t, not int, to count
12648 sizes, since they can exceed INT_MAX in size. Check for size
12649 calculation overflow.
12651 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
12652 (xg_select): Check for size calculation overflow.
12653 Don't update size until alloc done.
12655 * xrdb.c (get_environ_db): Don't assume path length fits in int,
12656 as sprintf is limited to int lengths.
12658 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
12659 (X_LONG_MIN): New macros.
12660 Use them to make the following changes clearer.
12661 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
12662 This change doesn't affect the value now, but it may help remind
12663 future maintainers not to raise the value too much later.
12664 (SELECTION_QUANTUM): Remove, replacing with ...
12665 (selection_quantum): ... new function, which avoids overflow.
12667 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
12668 assumption that selection length fits in 'int'.

12685 Don't store size until memory allocation succeeds.
12686 (x_get_window_property): Plug memory leak on memory exhaustion.
12687 Don't double-block input; malloc is safe here. Don't assume 2**34
12688 - 4 fits in unsigned long. Add an xassert to check
12689 XGetWindowProperty overflow. Be more careful about overflow
12690 calculations, and distinguish size from memory overflow better.
12691 (receive_incremental_selection): When tracing, don't assume
12692 unsigned int is less than INT_MAX.
12693 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory

12697 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
12698 result parameters unless successful. Rely on cons_to_unsigned
12699 to report problems with elements; the old code wasn't right anyway.
12700 (x_check_property_data): Check for int overflow; we cannot use
12701 a wider type due to X limits.

12734 * lisp.h (hash_lookup, hash_put):
12735 * minibuf.c (Ftest_completion):
12736 Use ptrdiff_t for hash table indexes, not int (which is too
12737 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
12738 32-bit --with-wide-int hosts).
12740 * charset.c (Fdefine_charset_internal): Check for integer overflow.
12741 Add a FIXME comment about memory leaks.

12749 with outlandish widths.
12750 * character.h (sanitize_tab_width): Rename from sanitize_width,
12751 now that we have two such functions. All uses changed.

12769 * xterm.c: Don't go over XClientMessageEvent limit.
12770 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
12771 (x_send_scroll_bar_event): Likewise. Check that the size does not
12772 exceed limits imposed by XClientMessageEvent, as well as the usual
12773 ptrdiff_t and size_t limits.
12775 * keyboard.c: Overflow, signedness and related fixes.
12776 (make_lispy_movement): Use same integer type in forward decl
12777 that is used in the definition.
12778 (read_key_sequence, keyremap_step):
12779 Change bufsize argument back to int, undoing my 2011-03-30 change.
12780 We prefer signed types, and int is wide enough here.
12781 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
12782 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
12783 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
12784 length, not size_t. Use ptrdiff_t for index, not int.
12785 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
12786 possibility of integer overflow.
12788 Overflow, signedness and related fixes for images.

12814 Prefer int to unsigned where either will do.
12815 (tiff_handler): New function, combining the cores of the
12816 old tiff_error_handler and tiff_warning_handler.
12817 This function is rewritten to use vsnprintf and thereby avoid
12818 stack buffer overflows. It uses only the features of vsnprintf
12819 that are common to both POSIX and native Microsoft.
12820 (tiff_error_handler, tiff_warning_handler): Use it.
12821 (tiff_load, gif_load, imagemagick_load_image):
12822 Don't assume :index value fits in 'int'.
12823 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
12824 (imagemagick_load_image): Check that crop parameters fit into
12825 the integer types that MagickCropImage accepts. Don't assume
12826 Vimagemagick_render_type has a nonnegative value. Don't assume
12827 size_t fits in 'long'.
12828 (gs_load): Use printmax_t to print the widest integers possible.

12841 handle_single_display_spec, not just 1 or zero.
12842 (handle_single_display_spec): If the display spec is of the form
12843 `(space ...)', and specifies display in the text area, return 2
12845 (try_cursor_movement): Check for the need to scroll more
12846 accurately, and prefer exact match for point under bidi.
12847 Don't advance `row' beyond the last row of the window.

12865 buffers, return left-to-right.
12866 (set_cursor_from_row): Consider candidate row a win if its glyph
12867 represents a newline and point is on that newline. Fixes cursor
12868 positioning on the newline at EOL of R2L text within L2R
12869 paragraph, and vice versa.
12870 (try_cursor_movement): Check continued rows, in addition to
12871 continuation rows. Fixes unwarranted scroll when point enters a
12872 continued line of R2L text within an L2R paragraph, or vice versa.
12873 (cursor_row_p): Consider the case of point being equal to
12874 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving

12903 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
12904 instead of CHAR_TO_BYTE. Fixes a crash when a completion
12905 candidate is selected by the mouse, and that candidate has a
12906 composed character under the mouse.
12908 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
12909 coordinates reported by pos-visible-in-window-p for a composed
12910 character in column zero.

12919 consider it a hit if to_charpos is anywhere in the range of the
12920 composed buffer positions.
12922 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
12924 * image.c (gif_load): Don't assume that each subimage has the same
12925 dimensions as the base image. Handle disposal method that is
12926 "undefined" by the gif spec (Bug#9335).
12928 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
12930 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

12940 a composition, take its buffer position from IT->cmp_it.charpos.
12941 Fixes cursor positioning at the beginning of a line that begins
12942 with a composed character.
12944 2011-08-18 Eli Zaretskii <eliz@gnu.org>
12946 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
12947 character bidirectional type, use STRONG_L instead. Fixes crashes
12948 in a buffer produced by `describe-categories'.
12950 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
12951 members before the level stack, so they would be saved and
12952 restored when copying iterator state. Fixes incorrect reordering
12953 around TABs covered by display properties.
12955 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>

13023 after the pid of the process is set to -1 (Bug#8162).
13025 2011-08-14 Eli Zaretskii <eliz@gnu.org>
13027 * xdisp.c (move_it_in_display_line_to): Don't invoke
13028 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
13029 ppos_it. Fixes vertical cursor motion when line beginning is
13030 covered by an image. (Bug#9296)
13032 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
13034 * nsterm.h (ns_run_ascript): Declare.
13035 (NSAPP_DATA2_RUNASSCRIPT): Define.
13037 * nsfns.m (as_script, as_result, as_status): New static variables.
13038 (ns_run_ascript): New function.
13039 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
13040 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
13041 the event loop. Get status from as_status (Bug#7276).
13043 * nsterm.m (sendEvent): If event is NSApplicationDefined and
13044 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
13045 the event loop (Bug#7276).
13047 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
13049 * gnutls.c (QCgnutls_bootprop_priority)
13050 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
13051 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
13052 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
13053 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
13054 (QCgnutls_bootprop_verify_hostname_error)
13055 (QCgnutls_bootprop_callbacks_verify): Rename from
13056 Qgnutls_bootprop_..., all uses changed.
13058 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
13061 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
13063 * xfaces.c (Qframe_set_background_mode): Now static.
13064 * dispextern.h (Qframe_set_background_mode): Remove decl.
13066 * process.c (Fnetwork_interface_info): Declare local only if needed.
13068 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
13070 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
13071 (Fnetwork_interface_list): Allocate in increments of bytes instead
13072 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
13073 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
13075 (struct ifflag_def): notrailers is smart on OSX.
13076 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
13077 Get hardware address with getifaddrs if available.
13079 2011-08-12 Eli Zaretskii <eliz@gnu.org>
13081 * xdisp.c (iterate_out_of_display_property): xassert that
13082 IT->position is set to within IT->object's boundaries. Break from
13083 the loop as soon as EOB is reached; avoids infloops in redisplay
13084 when IT->position is set up wrongly due to some bug.
13085 Set IT->current to match the bidi iterator unconditionally.
13086 (push_display_prop): Allow GET_FROM_STRING as IT->method on
13087 entry. Force push_it to save on the stack the current
13088 buffer/string position, to be restored by pop_it. Fix flags in
13089 the iterator structure wrt the object coming from a display
13090 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
13091 properties. (Bug#9284)
13093 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
13095 * fontset.c (fontset_get_font_group): Add proper type checks.
13098 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
13100 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
13101 and LC_VERSION_MIN_MACOSX.
13102 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
13103 (dump_it) [LC_FUNCTION_STARTS]: Use it.
13105 2011-08-08 Eli Zaretskii <eliz@gnu.org>
13107 * xdisp.c (forward_to_next_line_start): Allow to use the
13108 no-display-properties-and-no-overlays under bidi display.
13109 Set disp_pos in the bidi iterator to avoid searches for display
13110 properties and overlays.
13112 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
13114 * editfns.c (Fset_time_zone_rule): Document relationship with the
13117 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
13118 the font entity extracted from the cache (Bug#8109).
13120 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
13122 * composite.c (autocmp_chars): Don't reset point. That is done by
13123 restore_point_unwind (Bug#5984).
13125 2011-08-07 Juri Linkov <juri@jurta.org>
13127 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
13128 to show the arg `TIME' instead of `TIMEVAL'.
13130 2011-08-06 Eli Zaretskii <eliz@gnu.org>
13132 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
13133 display property strides EOL and includes a newline, as in
13134 longlines-mode. (Bug#9254)
13135 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
13136 word-wrap under bidirectional display. (Bug#9224)
13138 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
13139 is non-zero, even if the data buffer is NULL. Fixes a crash in
13140 vertical-motion with longlines-mode. (Bug#9254)
13142 2011-08-05 Eli Zaretskii <eliz@gnu.org>
13144 * bidi.c <bidi_cache_total_alloc>: Now static.
13145 (bidi_initialize): Initialize bidi_cache_total_alloc.
13147 * xdisp.c (display_line): Release buffer allocated for shelved bidi
13150 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
13151 amount allocated this far in `bidi_cache_total_alloc'.
13152 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
13153 non-zero, only free the data buffer without restoring the cache
13154 contents. All callers changed.
13156 * dispextern.h (bidi_unshelve_cache): Update prototype.
13158 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
13159 (move_it_in_display_line, move_it_to)
13160 (move_it_vertically_backward, move_it_by_lines): Replace the call
13161 to xfree to an equivalent call to bidi_unshelve_cache.
13162 (move_it_in_display_line_to): Fix logic of returning
13163 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
13165 2011-08-05 Eli Zaretskii <eliz@gnu.org>
13167 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
13168 came from a string character with a `cursor' property. (Bug#9229)
13170 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
13172 * Makefile.in (LIB_PTHREAD): New variable.
13173 (LIBES): Add LIB_PTHREAD (Bug#9216).
13175 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
13176 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
13178 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
13180 * regex.c (re_iswctype): Remove some redundant boolean conversions.
13182 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
13184 * xterm.c (x_find_topmost_parent): New function.
13185 (x_set_frame_alpha): Find topmost parent window with
13186 x_find_topmost_parent and set the property there also (bug#9181).
13187 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
13189 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
13191 * callproc.c (Fcall_process): Avoid vfork clobbering
13192 the local vars buffer, coding_systems, current_dir.
13194 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
13196 * keymap.c (Fmake_composed_keymap): Move to subr.el.
13198 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
13200 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
13201 so that it is not optimized away.
13203 * xdisp.c (compute_display_string_pos): Remove unused local.
13205 2011-08-02 Eli Zaretskii <eliz@gnu.org>
13207 Fix slow cursor motion and scrolling in large buffers with
13208 selective display, like Org Mode buffers. (Bug#9218)
13210 * dispextern.h (struct bidi_it): New member disp_prop_p.
13212 * xdisp.c: Remove one-slot cache of display string positions.
13213 (compute_display_string_pos): Accept an additional argument
13214 DISP_PROP_P; callers changed. Scan at most 5K characters forward
13215 for a display string or property. If found, set DISP_PROP_P
13218 * bidi.c (bidi_fetch_char): Accept an additional argument
13219 DISP_PROP_P, and pass it to compute_display_string_pos.
13220 Only handle text covered by a display string if DISP_PROP_P is returned
13221 non-zero. All callers of bidi_fetch_char changed.
13223 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
13225 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
13227 2010-12-03 Don March <don@ohspite.net>
13229 * keymap.c (Fdefine_key): Fix non-prefix key error message when
13230 last character M-[char] is translated to ESC [char] (bug#7541).
13232 2011-08-02 Kenichi Handa <handa@m17n.org>
13234 * lisp.h (uniprop_table): Extern it.
13236 * chartab.c (uniprop_table): Make it non-static.
13238 2011-08-01 Eli Zaretskii <eliz@gnu.org>
13240 * xdisp.c (forward_to_next_line_start): Accept additional argument
13241 BIDI_IT_PREV, and store into it the state of the bidi iterator had
13243 (reseat_at_next_visible_line_start): Use the bidi iterator state
13244 returned by forward_to_next_line_start to restore the state of
13245 it->bidi_it after backing up to previous newline. (Bug#9212)
13247 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
13249 * regex.c (re_comp): Protoize.
13250 (re_exec): Fix return type.
13251 (regexec): Fix type of `ret'. (Bug#9203)
13253 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
13255 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
13256 This is needed if max-image-size is a floating-point number.
13258 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
13260 * print.c (print_object): Print empty symbol as ##.
13262 * lread.c (read1): Read ## as empty symbol.
13264 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
13266 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
13267 setting frame foreground color (Bug#9175).
13268 (x_set_background_color): Likewise.
13270 * nsmenu.m (-setText): Size tooltip dimensions precisely to
13271 contents (Bug#9176).
13272 (EmacsTooltip -init): Remove bezels and add shadows to
13275 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
13276 or scroll bar (Bug#8470).
13278 * nsfont.m (nsfont_open): Remove assignment to voffset and
13279 unnecessary vars hshink, expand, hd, full_height, min_height.
13280 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
13282 * nsterm.h (nsfont_info): Remove voffset field.
13284 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
13286 Implement strike-through and overline on NextStep (Bug#8863).
13288 * nsfont.m (nsfont_open): Use underline position provided by font,
13289 instead of hard-coded value of 2.
13290 (nsfont_draw): Call ns_draw_text_decoration instead.
13292 * nsterm.h: Add declaration for ns_draw_text_decoration.
13294 * nsterm.m (ns_draw_text_decoration): New function for drawing
13295 underline, overline, and strike-through.
13296 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
13297 ns_draw_text_decoration. Change treatment of cursor drawing to
13298 accommodate underlining, etc.
13300 2011-07-28 Eli Zaretskii <eliz@gnu.org>
13302 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
13305 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
13307 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
13308 Without this fix, if a signal arrives just after memory fills up,
13309 'malloc' might be invoked reentrantly.
13311 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
13312 In other words, assume that every image size is allowed, on non-X
13313 hosts. This assumption is probably wrong, but it lets Emacs compile.
13315 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
13317 * regex.c (re_iswctype): Convert return values to boolean.
13319 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
13321 * xdisp.c (compute_display_string_pos): Don't use cached display
13322 string position if the buffer had its restriction changed.
13325 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
13327 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
13329 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
13331 Integer signedness and overflow and related fixes. (Bug#9079)
13333 * bidi.c: Integer size and overflow fixes.
13334 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
13335 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
13336 (bidi_cache_find_level_change, bidi_cache_ensure_space)
13337 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
13338 (bidi_find_other_level_edge):
13339 Use ptrdiff_t instead of EMACS_INT where either will do.
13340 This works better on 32-bit hosts configured --with-wide-int.
13341 (bidi_cache_ensure_space): Check for size-calculation overflow.
13342 Use % rather than repeated addition, for better worst-case speed.
13343 Don't set bidi_cache_size until after xrealloc returns, because it
13345 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
13346 (bidi_cache_ensure_space): Also check that the bidi cache size
13347 does not exceed that of the largest Lisp string or buffer. See Eli
13348 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
13350 * alloc.c (__malloc_size_t): Remove.
13351 All uses replaced by size_t. See Andreas Schwab's note
13352 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
13354 * image.c: Improve checking for integer overflow.
13355 (check_image_size): Assume that f is nonnull, since
13356 it is always nonnull in practice. This is one less thing to
13357 worry about when checking for integer overflow later.
13358 (x_check_image_size): New function, which checks for integer
13359 overflow issues inside X.
13360 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
13361 This removes the need for a memory_full check.
13362 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
13363 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
13364 (xbm_read_bitmap_data): Change locals back to 'int', since
13365 their values must fit in 'int'.
13366 (xpm_load_image, png_load, tiff_load):
13367 Invoke x_create_x_image_and_pixmap earlier,
13368 to avoid much needless work if the image is too large.
13369 (tiff_load): Treat overly large images as if
13370 x_create_x_image_and_pixmap failed, not as malloc failures.
13371 (gs_load): Use x_check_image_size.
13373 * gtkutil.c: Omit integer casts.
13374 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
13375 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
13377 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
13379 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
13380 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
13381 would wrongly return t on a 64-bit host.
13383 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
13384 The plain *_OVERFLOW macros run afoul of GCC bug 49705
13385 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
13386 and therefore cause GCC to emit a bogus diagnostic in some cases.
13388 * image.c: Integer signedness and overflow and related fixes.
13389 This is not an exhaustive set of fixes, but it's time to
13390 record what I've got.
13391 (lookup_pixel_color, check_image_size): Remove redundant decls.
13392 (check_image_size): Don't assume that arbitrary EMACS_INT values
13393 fit in 'int', or that arbitrary 'double' values fit in 'int'.
13394 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
13395 (tiff_load, imagemagick_load_image):
13396 Check for overflow in size calculations.
13397 (x_create_x_image_and_pixmap): Remove unnecessary test for
13398 xmalloc returning NULL; that can't happen.
13399 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
13400 (xpm_color_bucket): Use better integer hashing function.
13401 (xpm_cache_color): Don't possibly over-allocate memory.
13402 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
13403 (gif_memory_source):
13404 Use ptrdiff_t, not int or size_t, to record sizes.
13405 (png_load): Don't assume values greater than 2**31 fit in 'int'.
13406 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
13407 either works, as we prefer signed integers.
13408 (tiff_read_from_memory, tiff_write_from_memory):
13409 Return tsize_t, not size_t, since that's what the TIFF API wants.
13410 (tiff_read_from_memory): Don't fail simply because the read would
13411 go past EOF; instead, return a short read.
13412 (tiff_load): Omit no-longer-needed casts.
13413 (Fimagemagick_types): Don't assume size fits into 'int'.
13415 Improve hashing quality when configured --with-wide-int.
13416 * fns.c (hash_string): New function, taken from sxhash_string.
13417 Do not discard information about ASCII character case; this
13418 discarding is no longer needed.
13419 (sxhash-string): Use it. Change sig to match it. Caller changed.
13420 * lisp.h: Declare it.
13421 * lread.c (hash_string): Remove, since we now use fns.c's version.
13422 The fns.c version returns a wider integer if --with-wide-int is
13423 specified, so this should help the quality of the hashing a bit.
13425 * emacs.c: Integer overflow minor fix.
13426 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
13427 Define only if GNU_LINUX.
13428 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
13430 * dispnew.c: Integer signedness and overflow fixes.
13431 Remove unnecessary forward decls, that were a maintenance hassle.
13432 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
13434 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
13435 (scrolling_window): Use ptrdiff_t, not int, for byte count.
13436 (prepare_desired_row, line_draw_cost):
13437 Use int, not unsigned, where either works.
13438 (save_current_matrix, restore_current_matrix):
13439 Use ptrdiff_t, not size_t, where either works.
13440 (init_display): Check for overflow more accurately, and without
13441 relying on undefined behavior.
13443 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
13444 Remove, replacing with the new symbols in lisp.h. All uses changed.
13445 * fileio.c (make_temp_name):
13446 * filelock.c (lock_file_1, lock_file):
13447 * xdisp.c (message_dolog):
13448 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
13449 Use pMd etc. instead.
13450 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
13451 replacing the pWIDE etc. symbols removed from editfns.c.
13453 * keyboard.h (num_input_events): Now uintmax_t.
13454 This is (very slightly) less likely to mess up due to wraparound.
13457 * buffer.c: Integer signedness fixes.
13458 (alloc_buffer_text, enlarge_buffer_text):
13459 Use ptrdiff_t rather than size_t when either will do, as we prefer
13462 * alloc.c: Integer signedness and overflow fixes.
13463 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
13464 (__malloc_size_t): Default to size_t, not to int.
13465 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
13466 (Fgarbage_collect, mark_object_loop_halt, mark_object):
13467 Prefer ptrdiff_t to size_t when either would do, as we prefer
13469 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
13470 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
13471 Now const. Initialize with values that are in range even if char
13473 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
13474 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
13475 These functions do the right thing with sizes > 2**32.
13476 (check_depth): Now ptrdiff_t, not int.
13477 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
13478 Adjust to new way of storing sizes. Check for size overflow bugs
13480 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
13481 slightly wrong anyway, as it missed one instance of
13482 XMALLOC_OVERRUN_CHECK_OVERHEAD.
13483 (refill_memory_reserve): Omit needless cast to size_t.
13484 (mark_object_loop_halt): Mark as externally visible.
13486 * xselect.c: Integer signedness and overflow fixes.
13487 (Fx_register_dnd_atom, x_handle_dnd_message):
13488 Use ptrdiff_t, not size_t, since we prefer signed.
13489 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
13490 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
13491 x_dnd_atoms_size and x_dnd_atoms_length.
13493 * doprnt.c: Prefer signed to unsigned when either works.
13495 * doprnt.c (doprnt):
13497 * xdisp.c (vmessage):
13498 Use ptrdiff_t, not size_t, when using or implementing doprnt,
13499 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
13500 prefer signed arithmetic to avoid comparison confusion.
13501 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
13502 but is a bit tricky.
13504 Assume freestanding C89 headers, string.h, stdlib.h.
13505 * data.c, doprnt.c, floatfns.c, print.c:
13506 Include float.h unconditionally.
13507 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
13508 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
13509 * regex.c: Likewise for stddef.h, string.h.
13510 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
13511 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
13512 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
13513 (STDC_HEADERS): Remove obsolete defines.
13514 * sysdep.c: Include limits.h unconditionally.
13516 Assume support for memcmp, memcpy, memmove, memset.
13517 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
13518 * regex.c (memcmp, memcpy):
13519 Remove; we assume C89 now.
13521 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
13522 (__malloc_safe_bcopy): Remove; no longer needed.
13524 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
13525 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
13526 well either way, and we prefer signed to unsigned.
13528 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
13530 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
13531 closes the connection while we're reading (bug#9182).
13533 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
13535 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
13536 are specified (Bug#9168).
13538 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
13540 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
13541 Found by GCC static checking and --with-wide-int on a 32-bit host.
13543 2011-07-25 Eli Zaretskii <eliz@gnu.org>
13545 * xdisp.c (compute_display_string_pos): Fix logic of caching
13546 previous display string position. Initialize cached_prev_pos to
13547 -1. Fixes slow-down at the beginning of a buffer.
13549 2011-07-24 Eli Zaretskii <eliz@gnu.org>
13551 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
13552 for attrs[LFACE_FONTSET_INDEX].
13554 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
13556 * xml.c (parse_region): Remove unused local
13557 that was recently introduced.
13559 2011-07-23 Eli Zaretskii <eliz@gnu.org>
13561 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
13562 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
13564 * xdisp.c (move_it_in_display_line_to): Record the best matching
13565 position for TO_CHARPOS while scanning the line, and restore it on
13566 exit if none of the characters scanned was an exact match.
13567 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
13568 when exact match is impossible due to invisible text, and the
13569 lines are truncated.
13571 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
13573 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
13576 2011-07-22 Eli Zaretskii <eliz@gnu.org>
13578 Fix a significant slow-down of cursor motion with C-n, C-p,
13579 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
13580 auto-repeat under bidi redisplay in fontified buffers.
13581 * xdisp.c (compute_stop_pos_backwards): New function.
13582 (next_element_from_buffer): Call compute_stop_pos_backwards to
13583 find a suitable prev_stop when we find ourselves before
13585 (reseat): Don't look for prev_stop, as that could mean a very long
13587 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
13588 <cached_disp_overlay_modiff>: Cache for last found display string
13590 (compute_display_string_pos): Return the cached position if asked
13591 about the same buffer in the same area of character positions, and
13592 the buffer wasn't changed since the time the display string
13593 position was cached.
13595 2011-07-22 Eli Zaretskii <eliz@gnu.org>
13597 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
13598 is an integer, which is important for empty lines. (Bug#9149)
13600 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
13602 * frame.c (Fmodify_frame_parameters): In tty case, update the
13603 default face if necessary (Bug#4238).
13605 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
13607 * editfns.c (Fstring_to_char): No need to explain what a character
13608 is in the docstring (Bug#6576).
13610 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
13612 * xml.c (parse_region): Make sure we always return a tree.
13614 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
13616 * xml.c (parse_region): If a document contains only comments,
13619 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
13621 * xml.c (make_dom): Return comments, too.
13623 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
13626 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
13627 and the surrounding thread.
13628 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
13629 rather than fgets, and retry after EINTR. Otherwise, 'emacs
13630 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
13632 * s/openbsd.h (BROKEN_SIGIO): Define.
13633 * unexelf.c (unexec) [__OpenBSD__]:
13634 Don't update the .mdebug section of the Alpha COFF symbol table.
13636 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
13638 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
13641 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
13643 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
13644 This fixes some race conditions on the permissions of any newly
13647 * alloc.c (valid_pointer_p): Use pipe, not open.
13648 This fixes some permissions issues when debugging.
13650 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
13651 If fchown fails to set both uid and gid, try to set just gid,
13652 as that is sometimes allowed. Adjust the file's mode to eliminate
13653 setuid or setgid bits that are inappropriate if fchown fails.
13655 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
13657 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
13658 to compare Lisp_Objects.
13659 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
13660 global_gnutls_log_level, don't mistake it for a Lisp_Object.
13661 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
13663 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
13665 * lread.c (read_integer): Unread even EOF character.
13666 (read1): Likewise. Properly record start position of symbol.
13668 * lread.c (read1): Read `#:' as empty uninterned symbol if no
13669 symbol character follows.
13671 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
13673 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
13674 This works around a problem with the previous change to Fcopy_file.
13675 Recent glibc declares fchown with __attribute__((warn_unused_result)),
13676 and without this change, GCC might complain about discarding
13677 fchown's return value.
13679 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
13681 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
13683 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
13685 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
13687 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
13689 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
13690 it's used from the C level.
13692 * process.c: Use the same condition for POLL_FOR_INPUT in both
13693 keyboard.c and process.c (bug#1858).
13695 2011-07-09 Lawrence Mitchell <wence@gmx.li>
13697 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
13698 (Fgnutls_boot): Use it.
13700 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
13702 * doc.c (Fsubstitute_command_keys): Revert last change.
13704 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
13706 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
13707 quotes the next character, and doesn't affect other longer
13708 sequences (bug#8935).
13710 * lread.c (syms_of_lread): Clarify that is isn't only
13711 `eval-buffer' and `eval-defun' that's affected by
13712 `lexical-binding' (bug#8460).
13714 2011-07-15 Eli Zaretskii <eliz@gnu.org>
13716 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
13717 bidi redisplay when a line includes both an image and is truncated.
13719 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
13721 Fix minor problems found by static checking.
13722 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
13723 (elsz): Now a signed constant, not a size_t var. We prefer signed
13724 types to unsigned, to avoid integer comparison confusion. Without
13725 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
13726 "cannot optimize loop, the loop counter may overflow", a symptom
13728 * indent.c (Fvertical_motion): Mark locals as initialized.
13729 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
13731 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
13733 * search.c (Fre_search_backward): Mention `case-fold-search' in
13734 all the re_search_* functions (bug#8138).
13736 * keyboard.c (Fopen_dribble_file): Document when the file is
13739 2011-07-14 Eli Zaretskii <eliz@gnu.org>
13741 * bidi.c (bidi_dump_cached_states): Fix format of displaying
13744 Support bidi reordering of display and overlay strings.

13746 (compute_display_string_end): Accept additional argument STRING.
13747 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
13748 (reseat_to_string): Initialize bidi_it->string.s and
13749 bidi_it->string.schars.
13750 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
13751 NULL (avoids a crash in bidi_paragraph_init).
13752 Initialize itb.string.lstring.
13753 (init_iterator): Call bidi_init_it only of a valid
13754 buffer position was specified. Initialize paragraph_embedding to
13756 (reseat_to_string): Initialize the bidi iterator.
13757 (display_string): If we need to ignore text properties of
13758 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
13759 original value of -1 will not work with bidi.)
13760 (compute_display_string_pos): First arg is now struct
13761 `text_pos *'; all callers changed. Support display properties on
13763 (compute_display_string_end): Support display properties on Lisp
13765 (init_iterator, reseat_1, reseat_to_string): Initialize the
13766 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
13767 when iterating on a string not from display properties).
13768 (compute_display_string_pos, compute_display_string_end):
13769 Fix calculation of the object to scan. Fixes an error when using
13771 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
13772 base_level_stop; instead, set base_level_stop to BEGV.
13773 Fixes crashes in vertical-motion.
13774 (next_element_from_buffer): Improve commentary for when
13775 the iterator is before prev_stop.
13776 (init_iterator): Initialize bidi_p from the default value of
13777 bidi-display-reordering, not from buffer-local value. Use the
13778 buffer-local value only if initializing for buffer iteration.
13779 (handle_invisible_prop): Support invisible properties on strings
13780 that are being bidi-reordered.
13781 (set_iterator_to_next): Support bidi reordering of C strings and
13783 (next_element_from_string): Support bidi reordering of Lisp
13785 (handle_stop_backwards): Support Lisp strings as well.
13786 (display_string): Support display of R2L glyph rows.
13787 Use IT_STRING_CHARPOS when displaying from a Lisp string.
13788 (init_iterator): Don't initialize it->bidi_p for strings
13790 (reseat_to_string): Initialize it->bidi_p for strings here.
13791 (next_element_from_string, next_element_from_c_string)
13792 (next_element_from_buffer): Add xassert's for correspondence
13793 between IT's object being iterated and it->bidi_it.string
13795 (face_before_or_after_it_pos): Support bidi iteration.
13796 (next_element_from_c_string): Handle the case of the first string
13797 character that is not the first one in the visual order.
13798 (get_visually_first_element): New function, refactored from common
13799 parts of next_element_from_buffer, next_element_from_string, and
13800 next_element_from_c_string.
13801 (tool_bar_lines_needed, redisplay_tool_bar)
13802 (display_menu_bar): Force left-to-right direction. Add a FIXME
13803 comment for making that be controlled by a user option.
13804 (push_it, pop_it): Save and restore the state of the
13805 bidi iterator. Save and restore the bidi_p flag.
13806 (pop_it): Iterate out of display property for string iteration as
13808 (iterate_out_of_display_property): Support iteration over strings.
13809 (handle_single_display_spec): Set up it->bidi_it for iteration
13810 over a display string, and call bidi_init_it.
13811 (handle_single_display_spec, next_overlay_string)
13812 (get_overlay_strings_1, push_display_prop): Set up the bidi
13813 iterator for displaying display or overlay strings.
13814 (forward_to_next_line_start): Don't use the shortcut if
13816 (back_to_previous_visible_line_start): If handle_display_prop
13817 pushed the iterator stack, restore the internal state of the bidi
13818 iterator by calling bidi_pop_it same number of times.
13819 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
13820 and we are bidi-iterating, don't decrement the iterator position;
13821 instead, set the first_elt flag in the bidi iterator, to produce
13823 (reseat_1): Remove redundant setting of string_from_display_prop_p.
13824 (push_display_prop): xassert that we are iterating a buffer.
13825 (push_it, pop_it): Save and restore paragraph_embedding member.
13826 (handle_single_display_spec, next_overlay_string)
13827 (get_overlay_strings_1, reseat_1, reseat_to_string)
13828 (push_display_prop): Set up the `unibyte' member of bidi_it.string
13829 correctly. Don't assume unibyte strings are not bidi-reordered.
13830 (compute_display_string_pos)
13831 (compute_display_string_end): Fix handling the case of C string.
13832 (push_it, pop_it): Save and restore from_disp_prop_p.
13833 (handle_single_display_spec, push_display_prop): Set the
13834 from_disp_prop_p flag.
13835 (get_overlay_strings_1): Reset the from_disp_prop_p flag.
13836 (pop_it): Call iterate_out_of_display_property only if we are
13837 popping after iteration over a string that came from a display
13838 property. Fix a typo in popping stretch info. Add an assertion
13839 for verifying that the iterator position is in sync with the bidi
13841 (handle_single_display_spec, get_overlay_strings_1)
13842 (push_display_prop): Fix initialization of paragraph direction for
13843 string when that of the parent object is not yet determined.
13844 (reseat_1): Call bidi_init_it to resync the bidi
13845 iterator with IT's position. (Bug#7616)
13846 (find_row_edges): If ROW->start.pos gives position
13847 smaller than min_pos, use it as ROW->minpos. (Bug#7616)
13848 (handle_stop, back_to_previous_visible_line_start, reseat_1):
13849 Reset the from_disp_prop_p flag.
13850 (SAVE_IT, RESTORE_IT): New macros.
13851 (pos_visible_p, face_before_or_after_it_pos)
13852 (back_to_previous_visible_line_start)
13853 (move_it_in_display_line_to, move_it_in_display_line)
13854 (move_it_to, move_it_vertically_backward, move_it_by_lines)
13855 (try_scrolling, redisplay_window, display_line): Use them when
13856 saving a temporary copy of the iterator and restoring it back.
13857 (back_to_previous_visible_line_start, reseat_1)
13858 (init_iterator): Empty the bidi cache "stack".
13859 (move_it_in_display_line_to): If iterator ended up at
13860 EOL, but we never saw any buffer positions smaller than
13861 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
13862 motion in bidi-reordered lines.
13863 (move_it_in_display_line_to): Record prev_method and prev_pos
13864 immediately before the call to set_iterator_to_next. Fixes cursor
13865 motion in bidi-reordered lines with stretch glyphs and strings
13866 displayed in margins. (Bug#8133) (Bug#8867)
13867 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
13869 (pos_visible_p): Support positions in bidi-reordered lines.
13870 Save and restore bidi cache.
13872 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.
13873 (bidi_paragraph_info): Delete unused struct.
13874 (bidi_cache_idx, bidi_cache_last_idx): Declare EMACS_INT.
13875 (bidi_cache_start): New variable.
13876 (bidi_cache_reset): Reset bidi_cache_idx to bidi_cache_start, not
13878 (bidi_cache_fetch_state, bidi_cache_search)
13879 (bidi_cache_find_level_change, bidi_cache_iterator_state)
13880 (bidi_cache_find, bidi_peek_at_next_level)

13884 (bidi_fetch_char): Accept new argument STRING; all callers
13885 changed. Support iteration over a string. Support strings with
13886 display properties. Support unibyte strings. Fix the type of
13887 `len' according to what STRING_CHAR_AND_LENGTH expects.
13888 (bidi_paragraph_init, bidi_resolve_explicit_1)
13889 (bidi_resolve_explicit, bidi_resolve_weak)
13890 (bidi_level_of_next_char, bidi_move_to_visually_next):
13891 Support iteration over a string.
13892 (bidi_set_sor_type, bidi_resolve_explicit_1)
13893 (bidi_resolve_explicit, bidi_type_of_next_char): ignore_bn_limit
13894 can now be zero (for strings); special values 0 and -1 were
13895 changed to -1 and -2, respectively.
13896 (bidi_char_at_pos): New function.
13897 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak):

13983 2011-07-13 Paul Eggert <eggert@cs.ucla.edu>
13985 * buffer.c (Fget_buffer_create): Initialize inhibit_shrinking.
13986 The old code sometimes used this field without initializing it.
13988 * alloc.c (gc_sweep): Don't read past end of array.
13989 In theory, the old code could also have corrupted Emacs internals,
13990 though it'd be very unlikely.

13994 * character.c (Fcharacterp): Don't advertise optional ignored

14093 Use pthread_sigmask, not sigprocmask (Bug#9010).
14094 sigprocmask is portable only for single-threaded applications, and
14095 Emacs can be multi-threaded when it uses GTK.

14133 variable firstTime not needed on OSX >= 10.6.

14253 (clone_per_buffer_values): Don't assume that
14254 sizeof (struct buffer) is a multiple of sizeof (Lisp_Object).
14255 This isn't true in general, and it's particularly not true
14256 if Emacs is configured with --with-wide-int.
14257 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
14258 New macros, used in the buffer.c change.

14294 Random fixes. E.g., (random) never returned negative values.
14295 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
14296 subseconds part to the entropy, as that's a bit more random.
14297 Prefer signed to unsigned, since the signedness doesn't matter and
14298 in general we prefer signed. When given a limit, use a
14299 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
14300 latter isn't right if USE_2_TAGS_FOR_INTS.
14301 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
14302 not 0..VALMASK. Don't discard "excess" bits that random () returns.

14312 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
14314 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
14315 This is more efficient than Ffile_directory_p and avoids a minor race.
14317 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
14319 * buffer.c (Foverlay_put): Say what the return value is
14322 * fileio.c (barf_or_query_if_file_exists): Check first if the file
14323 is a directory before asking whether to use the file name
14325 (barf_or_query_if_file_exists): Make the "File is a directory"
14326 error be more correct.
14328 * fns.c (Frequire): Remove the mention of the .gz files, since
14329 that's installation-specific, but keep the mention of
14330 `get-load-suffixes'.
14332 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
14334 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

14340 (syms_of_gnutls): Remove duplicate DEFSYM for

14447 * eval.c (struct backtrace): Simplify and port the data structure.
14448 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
14449 signed bit field, as this assumption is not portable and it makes
14450 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
14451 "char debug_on_exit : 1" as this is not portable either; instead,
14452 use the portable "unsigned int debug_on_exit : 1". Remove unused
14453 member evalargs. Remove obsolete comments about cc bombing out.

14689 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
14690 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
14691 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
14692 since we're not interested in debugging glyphs with old libraries.
14693 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
14694 GCC 4.6.0's static checking.

14736 (x_session_initialize): Do not assume string length fits in int.
14738 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.

14782 Invoke gzip -cd rather than gunzip, as it's more portable.
14783 (lock_info_type, lock_file_1, lock_file):
14784 Don't assume pid_t and time_t fit in unsigned long.
14785 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
14786 (current_lock_owner): Prefer signed type for sizes.
14787 Use memcpy, not strncpy, where memcpy is what is really wanted.
14788 Don't assume (via atoi) that time_t and pid_t fit in int.
14789 Check for time_t and/or pid_t out of range, e.g., via a network share.
14790 Don't alloca where an auto var works fine.
14792 * fileio.c: Fix some integer overflow issues.
14793 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
14794 Don't assume string length fits in int.
14795 (directory_file_name): Don't assume string length fits in long.
14796 (make_temp_name): Don't assume pid fits in int, or that its print
14797 length is less than 20.
14799 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
14801 * coding.c (make_subsidiaries): Don't assume string length fits in int.
14803 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
14805 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
14806 We prefer signed integers, even for size calculations.
14808 * emacs.c: Don't assume string length fits in 'int'.
14809 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
14810 (main): Don't invoke strlen when not needed.
14812 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
14813 (XD_DEBUG_MESSAGE): Don't waste a byte.
14815 * callproc.c (getenv_internal_1, getenv_internal)
14816 (Fgetenv_internal):
14817 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
14819 * lread.c (invalid_syntax): Omit length argument.
14820 All uses changed. This doesn't fix a bug, but it simplifies the
14821 code away from its former Hollerith-constant appearance, and it's
14822 one less 'int' to worry about when looking at integer-overflow issues.
14823 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
14825 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
14826 This didn't break anything, but it didn't help either.
14827 It's confusing to put a bogus integer in a place where the actual
14828 value does not matter.
14829 (LIST_END_P): Remove unused macro and its bogus comment.
14830 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
14832 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
14833 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
14835 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
14836 We prefer signed types, and the value cannot exceed the EMACS_INT
14837 range anyway (because otherwise the length would not be representable).
14838 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
14839 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
14840 This avoids a GCC warning when WIDE_EMACS_INT.
14842 * indent.c (sane_tab_width): New function.
14843 (current_column, scan_for_column, Findent_to, position_indentation)
14844 (compute_motion): Use it. This is just for clarity.
14845 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
14847 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
14849 * lisp.h (lint_assume): New macro.
14850 * composite.c (composition_gstring_put_cache):
14851 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
14853 * editfns.c, insdel.c:
14854 Omit unnecessary forward decls, to simplify future changes.
14856 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
14858 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
14860 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
14861 Use much-faster test for byte-length change.
14862 Don't assume string byte-length fits in 'int'.
14863 Check that character arg fits in 'int'.
14864 (mapcar1): Declare byte as byte, for clarity.
14866 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
14868 * fns.c (concat): Catch string overflow earlier.
14869 Do not rely on integer wraparound.
14871 * dispextern.h (struct it.overlay_strings_charpos)
14872 (struct it.selective): Now EMACS_INT, not int.
14873 * xdisp.c (forward_to_next_line_start)
14874 (back_to_previous_visible_line_start)
14875 (reseat_at_next_visible_line_start, next_element_from_buffer):
14876 Don't arbitrarily truncate the value of 'selective' to int.
14878 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
14880 * composite.c: Don't truncate sizes to 'int'.
14881 (composition_gstring_p, composition_reseat_it)
14882 (composition_adjust_point): Use EMACS_INT, not int.
14883 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
14884 not EMACS_UINT, for indexes.
14886 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
14888 * buffer.c: Include <verify.h>.
14889 (struct sortvec.priority, struct sortstr.priority):
14890 Now EMACS_INT, not int.
14891 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
14892 (struct sortstr.size, record_overlay_string)
14893 (struct sortstrlist.size, struct sortlist.used):
14894 Don't truncate size to int.
14895 (record_overlay_string): Check for size-calculation overflow.
14896 (init_buffer_once): Check at compile-time, not run-time.
14898 2011-06-22 Jim Meyering <meyering@redhat.com>
14900 Don't leak an XBM-image-sized buffer
14901 * image.c (xbm_load): Free the image buffer after using it.
14903 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
14906 * composite.c (find_automatic_composition): Omit needless 'return 0;'
14907 that Sun C diagnosed.
14908 * fns.c (secure_hash): Fix pointer signedness issue.
14909 * intervals.c (static_offset_intervals): New function.
14910 (offset_intervals): Use it.
14912 2011-06-21 Leo Liu <sdl.web@gmail.com>
14915 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
14918 * fns.c (secure_hash): Rename from crypto_hash_function and change
14919 the first arg to accept symbols.
14920 (Fsecure_hash): New primitive.
14921 (syms_of_fns): New symbols.
14923 2011-06-20 Deniz Dogan <deniz@dogan.se>
14925 * process.c (Fset_process_buffer): Clarify return value in
14928 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
14930 * dispnew.c (add_window_display_history): Use BVAR.
14932 * xdisp.c (debug_method_add): Use BVAR.
14933 (check_window_end, dump_glyph_matrix, dump_glyph)
14934 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
14936 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
14939 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
14940 check till after the cache is created in init_frame_faces.
14942 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
14944 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
14946 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
14948 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
14949 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
14950 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
14952 Improve buffer-overflow checking (Bug#8873).
14953 * fileio.c (Finsert_file_contents):
14954 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
14955 Remove the old (too-loose) buffer overflow checks.
14956 They weren't needed, since make_gap checks for buffer overflow.
14957 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
14958 The old code merely checked for Emacs fixnum overflow, and relied
14959 on undefined (wraparound) behavior. The new code avoids undefined
14960 behavior, and also checks for ptrdiff_t and/or size_t overflow.
14962 * editfns.c (Finsert_char): Don't dump core with very negative counts.
14963 Tune. Don't use wider integers than needed. Don't use alloca.
14964 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
14966 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
14968 * insdel.c, lisp.h (buffer_overflow): New function.
14969 (insert_from_buffer_1, replace_range, replace_range_2):
14970 * insdel.c (make_gap_larger):
14971 * editfns.c (Finsert_char):
14972 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
14974 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
14976 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
14978 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
14980 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
14981 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
14983 * fileio.c: Don't assume EMACS_INT fits in off_t.
14984 (emacs_lseek): New static function.
14985 (Finsert_file_contents, Fwrite_region): Use it.
14986 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
14988 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
14990 * fns.c: Don't overflow int when computing a list length.
14991 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
14992 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
14993 truncation on 64-bit hosts. Check for QUIT every
14994 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
14995 faster and is responsive enough.
14996 (Flength): Report an error instead of overflowing an integer.
14997 (Fsafe_length): Return a float if the value is not representable
14998 as a fixnum. This shouldn't happen except in contrived situations.
14999 (Fnthcdr, Fsort): Don't assume list length fits in int.
15000 (Fcopy_sequence): Don't assume vector length fits in int.
15002 * alloc.c: Check that resized vectors' lengths fit in fixnums.
15003 (header_size, word_size): New constants.
15004 (allocate_vectorlike): Don't check size overflow here.
15005 (allocate_vector): Check it here instead, since this is the only
15006 caller of allocate_vectorlike that could cause overflow.
15007 Check that the new vector's length is representable as a fixnum.
15009 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
15010 The previous code was bogus. For example, next_almost_prime (32)
15011 returned 39, which is undesirable as it is a multiple of 3; and
15012 next_almost_prime (24) returned 25, which is a multiple of 5 so
15013 why was the code bothering to check for multiples of 7?
15015 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
15017 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
15019 Variadic C functions now count arguments with ptrdiff_t.
15020 This partly undoes my 2011-03-30 change, which replaced int with size_t.
15021 Back then I didn't know that the Emacs coding style prefers signed int.
15022 Also, in the meantime I found a few more instances where arguments
15023 were being counted with int, which may truncate counts on 64-bit
15024 machines, or EMACS_INT, which may be unnecessarily wide.
15025 * lisp.h (struct Lisp_Subr.function.aMANY)
15026 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
15027 Arg counts are now ptrdiff_t, not size_t.
15028 All variadic functions and their callers changed accordingly.
15029 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
15030 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
15031 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
15032 * callint.c (Fcall_interactively): Check arg count for overflow,
15033 to avoid potential buffer overrun. Use signed char, not 'int',
15034 for 'varies' array, so that we needn't bother to check its size
15035 calculation for overflow.
15036 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
15037 * eval.c (apply_lambda):
15038 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
15039 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
15040 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
15042 * callint.c (Fcall_interactively): Don't use index var as event count.
15044 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
15045 * mem-limits.h (SIZE): Remove; no longer used.
15047 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
15049 Remove unnecessary casts.
15050 * xterm.c (x_term_init):
15051 * xfns.c (x_set_border_pixel):
15052 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
15053 These aren't needed now that we assume ANSI C.
15055 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
15056 It's more likely to cause problems (due to unsigned overflow)
15059 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
15061 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
15063 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
15065 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
15067 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
15069 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
15071 GLYPH_CODE_FACE returns EMACS_INT, not int.
15072 * dispextern.h (merge_faces):
15073 * xfaces.c (merge_faces):
15074 * xdisp.c (get_next_display_element, next_element_from_display_vector):
15075 Don't assume EMACS_INT fits in int.
15077 * character.h (CHAR_VALID_P): Remove unused parameter.
15078 * fontset.c, lisp.h, xdisp.c: All uses changed.
15080 * editfns.c (Ftranslate_region_internal): Omit redundant test.
15082 * fns.c (concat): Minor tuning based on overflow analysis.
15083 This doesn't fix any bugs. Use int to hold character, instead
15084 of constantly refetching from Emacs object. Use XFASTINT, not
15085 XINT, for value known to be a character. Don't bother comparing
15086 a single byte to 0400, as it's always less.
15088 * floatfns.c (Fexpt):
15089 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
15091 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
15094 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
15096 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
15097 Without this fix, on a 64-bit host (aset S 0 4294967386) would
15098 incorrectly succeed when S was a string, because 4294967386 was
15099 truncated before it was used.
15101 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
15102 Otherwise, an out-of-range integer could cause undefined behavior
15105 * composite.c: Use int, not EMACS_INT, for characters.
15106 (fill_gstring_body, composition_compute_stop_pos): Use int, not
15107 EMACS_INT, for values that are known to be in character range.
15108 This doesn't fix any bugs but is the usual style inside Emacs and
15109 may generate better code on 32-bit machines.
15111 Make sure a 64-bit char is never passed to ENCODE_CHAR.
15112 This is for reasons similar to the recent CHAR_STRING fix.
15113 * charset.c (Fencode_char): Check that character arg is actually
15114 a character. Pass an int to ENCODE_CHAR.
15115 * charset.h (ENCODE_CHAR): Verify that the character argument is no
15116 wider than 'int', as a compile-time check to prevent future regressions
15119 * character.c (char_string): Remove unnecessary casts.
15121 Make sure a 64-bit char is never passed to CHAR_STRING.
15122 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
15123 by silently ignoring the top 32 bits, allowing some values
15124 that were far too large to be valid characters.
15125 * character.h: Include <verify.h>.
15126 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
15127 arguments are no wider than unsigned, as a compile-time check
15128 to prevent future regressions in this area.
15130 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
15131 (Fsubst_char_in_region):
15133 * xdisp.c (decode_mode_spec_coding):
15134 Adjust to CHAR_STRING's new requirement.
15135 * editfns.c (Finsert_char, Fsubst_char_in_region):
15136 * fns.c (concat): Check that character args are actually
15137 characters. Without this test, these functions did the wrong
15138 thing with wildly out-of-range values on 64-bit hosts.
15140 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
15141 These casts should not be needed on 32-bit hosts, either.
15142 * keyboard.c (read_char):
15143 * lread.c (Fload): Remove casts to unsigned.
15145 * lisp.h (UNSIGNED_CMP): New macro.
15146 This fixes comparison bugs on 64-bit hosts.
15147 (ASCII_CHAR_P): Use it.
15148 * casefiddle.c (casify_object):
15149 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
15150 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
15151 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
15152 * dispextern.h (FACE_FROM_ID):
15153 * keyboard.c (read_char): Use UNSIGNED_CMP.
15155 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
15156 not to EMACS_INT, to avoid GCC warning.
15158 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
15160 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
15161 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
15162 isn't needed on 32-bit machines.
15164 * buffer.c (Fgenerate_new_buffer_name):
15165 Use EMACS_INT for count, not int.
15166 (advance_to_char_boundary): Return EMACS_INT, not int.
15168 * data.c (Qcompiled_function): Now static.
15170 * window.c (window_body_lines): Now static.
15172 * image.c (gif_load): Rename local to avoid shadowing.
15174 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
15175 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
15176 * alloc.c (make_save_value): Integer argument is now of type
15177 ptrdiff_t, not int.
15178 (mark_object): Use ptrdiff_t, not int.
15179 * lisp.h (pD): New macro.
15180 * print.c (print_object): Use it.
15182 * alloc.c: Use EMACS_INT, not int, to count objects.
15183 (total_conses, total_markers, total_symbols, total_vector_size)
15184 (total_free_conses, total_free_markers, total_free_symbols)
15185 (total_free_floats, total_floats, total_free_intervals)
15186 (total_intervals, total_strings, total_free_strings):
15187 Now EMACS_INT, not int. All uses changed.
15188 (Fgarbage_collect): Compute overall total using a double, so that
15189 integer overflow is less likely to be a problem. Check for overflow
15190 when converting back to an integer.
15191 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
15192 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
15193 These were 'int' variables that could overflow on 64-bit hosts;
15194 they were never used, so remove them instead of repairing them.
15195 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
15196 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
15197 Previously, this ceilinged at INT_MAX, but that doesn't work on
15199 (allocate_pseudovector): Don't use EMACS_INT when int would do.
15201 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
15202 (allocate_vectorlike): Check for ptrdiff_t overflow.
15203 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
15204 when a (possibly-narrower) signed value would do just as well.
15205 We prefer using signed arithmetic, to avoid comparison confusion.
15207 * alloc.c: Catch some string size overflows that we were missing.
15208 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
15209 for convenience in STRING_BYTES_MAX.
15210 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
15211 The definition here is exact; the one in lisp.h was approximate.
15212 (allocate_string_data): Check for string overflow. This catches
15213 some instances we weren't catching before. Also, it catches
15214 size_t overflow on (unusual) hosts where SIZE_MAX <= min
15215 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
15216 and ptrdiff_t and EMACS_INT are both 64 bits.
15218 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
15219 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.

15663 * character.h (MAYBE_UNIFY_CHAR):
15664 * charset.c (maybe_unify_char):
15665 * keyboard.c (read_char, reorder_modifiers):
15666 XINT -> XFASTINT, since the integer must be nonnegative.
15667 * ftfont.c (ftfont_spec_pattern):
15668 * keymap.c (access_keymap, silly_event_symbol_error):
15669 XUINT -> XFASTINT, since the integer must be nonnegative.
15670 (Fsingle_key_description, preferred_sequence_p): XUINT -> XINT,
15671 since it makes no difference and we prefer signed.
15672 * keyboard.c (record_char): Use XUINT when all the neighbors do.
15673 (access_keymap): NATNUMP -> INTEGERP, since the integer must be

15720 code. Minor doc-string fixes.
15722 2011-06-06 Paul Eggert <eggert@cs.ucla.edu>
15724 * alloc.c (memory_full) [SYSTEM_MALLOC]: Port to MacOS (Bug#8800).
15725 Do not assume that spare memory exists; that assumption is valid
15726 only if SYSTEM_MALLOC.
15727 (LARGE_REQUEST): New macro, so that the issue of large requests
15728 is separated from the issue of spare memory.
15730 2011-06-05 Andreas Schwab <schwab@linux-m68k.org>
15732 * editfns.c (Fformat): Correctly handle zero flag with hexadecimal

15758 New error handlers.
15759 (x_clipboard_manager_save_frame, x_clipboard_manager_save_all):
15760 Obey Vx_select_enable_clipboard_manager. Catch errors in
15761 x_clipboard_manager_save (Bug#8779).
15762 (Vx_select_enable_clipboard_manager): New variable.
15763 (x_get_foreign_selection): Reduce scope of x_catch_errors (Bug#8790).
15765 2011-06-04 Dan Nicolaescu <dann@ics.uci.edu>
15767 * emacs.c (main): Warn when starting a GTK emacs in daemon mode.
15769 2011-06-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15771 * fringe.c (update_window_fringes): Don't update overlay arrow bitmap
15772 in the current matrix if keep_current_p is non-zero.

15778 2011-06-03 Eli Zaretskii <eliz@gnu.org>
15780 Support bidi reordering of text covered by display properties.
15782 * bidi.c (bidi_copy_it): Use offsetof instead of emulating it.
15783 (bidi_fetch_char, bidi_fetch_char_advance): New functions.
15784 (bidi_cache_search, bidi_cache_iterator_state)
15785 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
15786 (bidi_level_of_next_char, bidi_move_to_visually_next):
15787 Support character positions inside a run of characters covered by a
15789 (bidi_paragraph_init, bidi_resolve_explicit_1)
15790 (bidi_level_of_next_char): Call bidi_fetch_char and
15791 bidi_fetch_char_advance instead of FETCH_CHAR and
15792 FETCH_CHAR_ADVANCE.

15794 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
15796 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
15797 instead of using explicit *_CHAR codes.
15798 (bidi_resolve_explicit, bidi_resolve_weak):
15799 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
15800 bidirectional text is supported only in multibyte buffers.
15801 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
15802 it to initialize the frame_window_p member of struct bidi_it.
15803 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
15804 (bidi_resolve_explicit, bidi_resolve_weak)

15806 bidi_it->nchars is non-positive.
15807 (bidi_level_of_next_char): Don't try to lookup the cache for the
15808 next/previous character if nothing is cached there yet, or if we
15809 were just reseat()'ed to a new position.
15811 * xdisp.c (set_cursor_from_row): Set start and stop points
15812 according to the row's direction when priming the loop that looks
15813 for the glyph on which to display cursor.
15814 (single_display_spec_intangible_p): Function deleted.
15815 (display_prop_intangible_p): Reimplement to call
15816 handle_display_spec instead of single_display_spec_intangible_p.
15817 Accept 3 additional arguments needed by handle_display_spec.
15818 This fixes incorrect cursor motion across display property with complex
15819 values: lists, `(when COND...)' forms, etc.
15820 (single_display_spec_string_p): Support property values that are
15821 lists with the argument STRING its top-level element.
15822 (display_prop_string_p): Fix the condition for processing a
15823 property that is a list to be consistent with handle_display_spec.
15824 (handle_display_spec): New function, refactored from the
15825 last portion of handle_display_prop.
15826 (compute_display_string_pos): Accept additional argument
15827 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
15828 value of a `display' property is a "replacing spec".
15829 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
15830 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
15831 the display property, but just return a value indicating whether
15832 the display property will replace the characters it covers.
15833 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
15834 frame_window_p members of struct bidi_it.
15835 (compute_display_string_pos, compute_display_string_end):
15837 (push_it): Accept second argument POSITION, where pop_it should
15838 jump to continue iteration.
15839 (reseat_1): Initialize bidi_it.disp_pos.
15841 * keyboard.c (adjust_point_for_property): Adjust the call to
15842 display_prop_intangible_p to its new signature.
15844 * dispextern.h (struct bidi_it): New member frame_window_p.
15845 (bidi_init_it): Update prototypes.
15846 (display_prop_intangible_p): Update prototype.
15847 (compute_display_string_pos, compute_display_string_end):
15848 Declare prototypes.
15849 (struct bidi_it): New members nchars and disp_pos. ch_len is now
15852 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
15854 Malloc failure behavior now depends on size of allocation.
15855 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
15856 * lisp.h: Change signatures accordingly.
15857 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
15858 All callers changed. (Bug#8762)
15860 * gnutls.c: Use Emacs's memory allocators.
15861 Without this change, the gnutls library would invoke malloc etc.
15862 directly, which causes problems on non-SYNC_INPUT hosts, and which
15863 runs afoul of improving memory_full behavior. (Bug#8761)
15864 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
15865 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
15866 xfree instead of the default malloc, realloc, free.
15867 (Fgnutls_boot): No need to check for memory allocation failure,
15868 since xmalloc does that for us.
15870 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
15871 * category.c (hash_get_category_set):
15872 * ccl.c (ccl_driver):

15884 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
15885 (Fsxhash, Fgethash, Fputhash, Fmaphash):
15886 * image.c (make_image, search_image_cache, lookup_image)
15887 (xpm_put_color_table_h):
15888 * lisp.h (struct Lisp_Hash_Table):
15889 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
15890 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
15891 for hashes and hash indexes, instead of 'unsigned' and 'int'.
15892 * alloc.c (allocate_vectorlike):
15893 Check for overflow in vector size calculations.
15894 * ccl.c (ccl_driver):
15895 Check for overflow when converting EMACS_INT to int.
15896 * fns.c, image.c: Remove unnecessary static decls that would otherwise
15897 need to be updated by these changes.
15898 * fns.c (make_hash_table, maybe_resize_hash_table):
15899 Check for integer overflow with large hash tables.
15900 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
15901 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
15902 (SXHASH_REDUCE): New macro.
15903 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
15904 Use it instead of discarding useful hash info with large hash values.
15905 (sxhash_float): New function.
15906 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
15907 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
15908 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
15909 Rewrite to use FIXNUM_BITS, as this simplifies things.
15910 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
15911 Adjust signatures to match updated version of code.
15912 (consing_since_gc): Now EMACS_INT, since a single hash table can
15913 use more than INT_MAX bytes.
15915 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
15917 Make it possible to build with GCC-4.6+ -O2 -flto.
15919 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
15921 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
15923 * minibuf.c (get_minibuffer, read_minibuf_unwind):
15924 Call minibuffer-inactive-mode.
15926 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
15928 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
15929 Update dependencies.
15931 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
15933 * data.c (init_data): Remove code for UTS, this system is not
15936 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
15938 Don't force ./temacs to start in terminal mode.
15940 * frame.c (make_initial_frame): Initialize faces in all cases, not
15941 only when CANNOT_DUMP is defined.
15942 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
15944 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
15946 * dispnew.c (add_window_display_history): Use const for the string
15947 pointer. Remove declaration, not needed.
15949 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
15951 Use 'inline', not 'INLINE'.
15952 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
15953 * alloc.c, fontset.c (INLINE): Remove.
15954 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
15955 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
15956 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
15957 * gmalloc.c (register_heapinfo): Use inline unconditionally.
15958 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
15960 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
15962 Make it possible to run ./temacs.
15964 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
15965 syms_of_callproc does the same thing. Remove test for
15966 "initialized", do it in the caller.
15967 * emacs.c (main): Avoid calling set_initial_environment when dumping.
15969 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
15971 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
15972 (read_minibuf): Use get_minibuffer.
15973 (syms_of_minibuf): Use DEFSYM.
15974 (Qmetadata): New var.
15975 * data.c (Qbuffer): Don't make it static.
15976 (syms_of_data): Use DEFSYM.
15978 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
15980 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
15981 (CCL_CODE_MIN): New macro.
15983 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
15985 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
15987 * eval.c (Qdebug): Now static.
15988 * lisp.h (Qdebug): Remove decl. This reverts a part of the
15989 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
15990 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
15992 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
15994 * image.c: Various fixes to ImageMagick code comments.
15995 (Fimagemagick_types): Doc fix.
15997 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
15999 Minor fixes prompted by GCC 4.6.0 warnings.
16001 * xselect.c (converted_selections, conversion_fail_tag): Now static.
16003 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
16004 (x_clipboard_manager_save_all): Move extern decl to ...
16005 * xterm.h: ... here, so that it can be checked for consistency.
16007 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
16009 * xselect.c (x_clipboard_manager_save_frame)
16010 (x_clipboard_manager_save_all): New functions.
16011 (Fx_clipboard_manager_save): Lisp function deleted.
16013 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
16014 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
16016 * xterm.h: Update prototype.
16018 2011-05-28 William Xu <william.xwl@gmail.com>
16020 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
16021 exiting (Bug#8239).
16023 2011-05-28 Jim Meyering <meyering@redhat.com>
16025 Avoid a sign-extension bug in crypto_hash_function.
16026 * fns.c (to_uchar): Define.
16027 (crypto_hash_function): Use it to convert some newly-signed
16028 variables to unsigned, to avoid sign-extension bugs. For example,
16029 without this change, (md5 "truc") would evaluate to
16030 45723a2aff78ff4fff7fff1114760e62 rather than the expected
16031 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
16032 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
16034 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
16036 Integer overflow fixes.
16038 * dbusbind.c: Serial number integer overflow fixes.
16039 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
16040 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
16041 to hold a serial number that is too large for a fixnum.
16042 (Fdbus_method_return_internal, Fdbus_method_error_internal):
16043 Check for serial numbers out of range. Decode any serial number
16044 that was so large that it became a float. (Bug#8722)
16046 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
16047 (Fdbus_call_method, Fdbus_call_method_asynchronously):
16048 Use XFASTINT rather than XUINT when numbers are nonnegative.
16049 (xd_append_arg, Fdbus_method_return_internal):
16050 (Fdbus_method_error_internal): Likewise. Also, for unsigned
16051 arguments, check that Lisp number is nonnegative, rather than
16052 silently wrapping negative numbers around. (Bug#8722)
16053 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
16056 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
16058 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
16060 ccl: Add integer overflow checks.
16061 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
16062 (IN_INT_RANGE): New macros.
16063 (ccl_driver): Use them to check for integer overflow when
16064 decoding a CCL program. Many of the new checks are whether XINT (x)
16065 fits in int; it doesn't always, on 64-bit hosts. The new version
16066 doesn't catch all possible integer overflows, but it's an
16067 improvement. (Bug#8719)
16069 * alloc.c (make_event_array): Use XINT, not XUINT.
16070 There's no need for unsigned here.
16072 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
16073 This follows up to the 2011-05-06 change that substituted uintptr_t
16074 for EMACS_INT. This case wasn't caught back then.
16076 Rework Fformat to avoid integer overflow issues.
16077 * editfns.c: Include <float.h> unconditionally, as it's everywhere
16078 now (part of C89). Include <verify.h>.
16079 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
16080 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
16081 (Fformat): Avoid the prepass trying to compute sizes; it was only
16082 approximate and thus did not catch overflow reliably. Instead, walk
16083 through the format just once, formatting and computing sizes as we go,
16084 checking for integer overflow at every step, and allocating a larger
16085 buffer as needed. Keep track separately whether the format is
16086 multibyte. Keep only the most-recently calculated precision, rather
16087 than them all. Record whether each argument has been converted to
16088 string. Use EMACS_INT, not int, for byte and char and arg counts.
16089 Support field widths and precisions larger than INT_MAX. Avoid
16090 sprintf's undefined behavior with conversion specifications such as %#d
16091 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
16092 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
16093 formatting out-of-range floating point numbers with int
16094 formats. (Bug#8668)
16096 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
16098 * data.c: Avoid integer truncation in expressions involving floats.
16099 * data.c: Include <intprops.h>.
16100 (arith_driver): When there's an integer overflow in an expression
16101 involving floating point, convert the integers to floating point
16102 so that the resulting value does not suffer from catastrophic
16103 integer truncation. For example, on a 64-bit host (* 4
16104 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
16105 Do not rely on undefined behavior after integer overflow.
16107 merge count_size_as_multibyte, parse_str_to_multibyte
16108 * character.c, character.h (count_size_as_multibyte):
16109 Rename from parse_str_to_multibyte; all uses changed.
16110 Check for integer overflow.
16111 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
16112 since it's now a duplicate of the other. This is more of
16113 a character than a buffer op, so better that it's in character.c.
16114 * fns.c, print.c: Adjust to above changes.
16116 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
16118 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
16120 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
16122 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
16123 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
16124 (x_clipboard_manager_save): Now static.
16125 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
16127 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
16128 (crypto_hash_function): Now static.
16129 Fix pointer signedness problems. Avoid unnecessary initializations.
16131 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
16133 * termhooks.h (Vselection_alist): Make it terminal-local.
16135 * terminal.c (create_terminal): Initialize it.
16137 * xselect.c: Support for clipboard managers.
16138 (Vselection_alist): Move to termhooks.h as terminal-local var.
16139 (LOCAL_SELECTION): New macro.
16140 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
16141 (symbol_to_x_atom): Remove gratuitous arg.
16142 (x_handle_selection_request, lisp_data_to_selection_data)
16143 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
16144 (x_own_selection, x_get_local_selection, x_convert_selection):
16145 New arg, specifying work frame. Use terminal-local Vselection_alist.
16146 (some_frame_on_display): Delete unused function.
16147 (Fx_own_selection_internal, Fx_get_selection_internal)
16148 (Fx_disown_selection_internal, Fx_selection_owner_p)
16149 (Fx_selection_exists_p): New optional frame arg.
16150 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
16151 (x_handle_selection_clear): Don't treat other terminals with the
16152 same keyboard specially. Use the terminal-local Vselection_alist.
16153 (x_clear_frame_selections): Use Frun_hook_with_args.
16155 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
16157 * xterm.h: Add support for those atoms.
16159 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
16161 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
16162 (converted_selections, conversion_fail_tag): New global variables.
16163 (x_selection_request_lisp_error): Free the above.
16164 (x_get_local_selection): Remove unnecessary code.
16165 (x_reply_selection_request): Args changed; handle arbitrary array
16166 of converted selections stored in converted_selections.
16167 Separate the XChangeProperty and SelectionNotify steps.
16168 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
16169 (x_convert_selection): New function.
16170 (x_handle_selection_event): Simplify.
16171 (x_get_foreign_selection): Don't ignore incoming requests while
16172 waiting for an answer; this will fail when we implement
16173 SAVE_TARGETS, and seems unnecessary anyway.
16174 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
16175 (Vx_sent_selection_functions): Doc fix.
16177 2011-05-26 Leo Liu <sdl.web@gmail.com>
16179 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
16181 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16183 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
16185 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
16186 for fringe update if it has periodic bitmap.
16187 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
16188 and fringe_bitmap_periodic_p.
16190 * fringe.c (get_fringe_bitmap_data): New function.
16191 (draw_fringe_bitmap_1, update_window_fringes): Use it.
16192 (update_window_fringes): Record periodicity of fringe bitmap in glyph
16193 row. Mark glyph row for fringe update if periodicity changed.
16195 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
16196 for fringe update unless it has periodic bitmap.
16198 2011-05-25 Kenichi Handa <handa@m17n.org>
16200 * xdisp.c (get_next_display_element): Set correct it->face_id for
16201 a static composition.
16203 2011-05-24 Leo Liu <sdl.web@gmail.com>
16206 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
16208 * fns.c (crypto_hash_function, Fsha1): New function.
16209 (Fmd5): Use crypto_hash_function.
16210 (syms_of_fns): Add Ssha1.
16212 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
16214 * gnutls.c: Remove unused macros.
16215 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
16216 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
16217 Remove macros that are defined and never used.
16218 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
16220 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
16222 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
16223 (Fx_get_selection_internal): Minor cleanup.
16224 (Fx_own_selection_internal): Rename arguments for consistency with
16227 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
16229 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
16231 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
16233 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
16235 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16237 * dispnew.c (scrolling_window): Don't exclude the case that the
16238 last enabled row in the desired matrix touches the bottom boundary.
16240 2011-05-21 Glenn Morris <rgm@gnu.org>
16242 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
16243 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
16244 and add some more files.
16246 2011-05-20 Eli Zaretskii <eliz@gnu.org>
16248 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
16249 report_file_error introduced by the change from 2011-05-07.
16251 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
16253 * systime.h (Time): Define only if emacs is defined.
16254 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
16255 where the include path doesn't have X11/X.h by default. See
16256 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
16258 2011-05-20 Kenichi Handa <handa@m17n.org>
16260 * composite.c (find_automatic_composition): Fix previous change.
16262 2011-05-20 Glenn Morris <rgm@gnu.org>
16264 * lisp.mk: New file, split from Makefile.in.
16265 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
16266 (shortlisp): Remove.
16267 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
16269 2011-05-19 Glenn Morris <rgm@gnu.org>
16271 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
16272 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
16273 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
16274 (lisp): Set the order to that of loadup.el.
16275 (shortlisp): Make it a copy of $lisp.
16276 (SOME_MACHINE_LISP): Remove.
16277 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
16278 Use just $shortlisp, not $SOME_MACHINE_LISP too.
16280 2011-05-18 Kenichi Handa <handa@m17n.org>
16282 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
16283 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
16284 (find_automatic_composition): Mostly rewrite for efficiency.
16286 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
16288 * makefile.w32-in: Update dependencies.
16290 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
16292 * menu.c: Include limits.h (fixes the MS-Windows build broken by
16293 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
16295 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
16297 Fix some integer overflow issues, such as string length overflow.
16299 * insdel.c (count_size_as_multibyte): Check for string overflow.
16301 * character.c (lisp_string_width): Check for string overflow.
16302 Use EMACS_INT, not int, for string indexes and lengths; in
16303 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
16304 the resulting string length overflows an EMACS_INT; instead,
16305 report a string overflow if no precision given. When checking for
16306 precision exhaustion, use a check that cannot possibly have
16307 integer overflow. (Bug#8675)
16308 * character.h (lisp_string_width): Adjust to new signature.
16310 * alloc.c (string_overflow): New function.
16311 (Fmake_string): Use it. This doesn't change behavior, but saves
16312 a few bytes and will simplify future changes.
16313 * character.c (string_escape_byte8): Likewise.
16314 * lisp.h (string_overflow): New decl.
16316 Fixups, following up to the user-interface timestamp change.
16317 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
16318 for UI timestamps, instead of unsigned long.
16319 * msdos.c (mouse_get_pos): Likewise.
16320 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
16321 * w32gui.h (Time): Define by including "systime.h" rather than by
16322 declaring it ourselves. (Bug#8664)
16324 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
16325 * image.c (clear_image_cache): Likewise.
16327 * term.c (term_mouse_position): Don't assume time_t wraparound.
16329 Be more systematic about user-interface timestamps.
16330 Before, the code sometimes used 'Time', sometimes 'unsigned long',
16331 and sometimes 'EMACS_UINT', to represent these timestamps.
16332 This change causes it to use 'Time' uniformly, as that's what X uses.
16333 This makes the code easier to follow, and makes it easier to catch
16334 integer overflow bugs such as Bug#8664.
16335 * frame.c (Fmouse_position, Fmouse_pixel_position):
16336 Use Time, not unsigned long, for user-interface timestamps.
16337 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
16338 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
16339 * keyboard.h (last_event_timestamp): Likewise.
16340 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
16341 * menu.h (xmenu_show): Likewise.
16342 * term.c (term_mouse_position): Likewise.
16343 * termhooks.h (struct input_event.timestamp): Likewise.
16344 (struct terminal.mouse_position_hook): Likewise.
16345 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
16346 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
16347 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
16348 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
16349 what it was before.
16350 * menu.h, termhooks.h: Include "systime.h", for Time.
16352 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
16353 Don't assume that the difference between two unsigned long values
16354 can fit into an integer. At this point, we know button_down_time
16355 <= event->timestamp, so the difference must be nonnegative, so
16356 there's no need to cast the result if double-click-time is
16357 nonnegative, as it should be; check that it's nonnegative, just in
16358 case. This bug is triggered when events are more than 2**31 ms
16359 apart (about 25 days). (Bug#8664)
16361 * xselect.c (last_event_timestamp): Remove duplicate decl.
16362 (x_own_selection): Remove needless cast to unsigned long.
16364 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
16365 that always fit in int. Use a sentinel instead of a counter, to
16366 avoid a temp and to allay GCC's concerns about possible int overflow.
16367 * frame.h (struct frame): Use int for menu_bar_items_used
16368 instead of EMACS_INT, since it always fits in int.
16370 * menu.c (grow_menu_items): Check for int overflow.
16372 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
16374 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
16375 Before, the code was not consistent. These values cannot exceed
16376 2**31 - 1 so there's no need to make them unsigned.
16377 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
16378 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
16379 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
16381 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
16383 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
16384 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
16385 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
16386 presumably because the widths might not match.
16388 * window.c (size_window): Avoid needless test at loop start.
16390 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
16392 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
16394 2011-05-12 Drew Adams <drew.adams@oracle.com>
16396 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
16398 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16400 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
16401 `width' to `bar_area_x' and `bar_area_width', respectively.
16402 (x_scroll_run): Take account of fringe background extension.
16404 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
16405 Rename local vars `left' and `width' to `bar_area_x' and
16406 `bar_area_width', respectively.
16407 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
16408 background extension.
16410 2011-05-10 Jim Meyering <meyering@redhat.com>
16412 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
16414 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
16416 * image.c (Finit_image_library): Return t for built-in image types,
16417 like pbm and xbm. (Bug#8640)
16419 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
16421 * w32menu.c (set_frame_menubar): Fix submenu allocation.
16423 2011-05-07 Eli Zaretskii <eliz@gnu.org>
16425 * w32console.c (Fset_screen_color): Doc fix.
16426 (Fget_screen_color): New function.
16427 (syms_of_ntterm): Defsubr it.
16429 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
16430 unlink the temporary file if Fcall_process didn't create it in the
16432 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
16433 child process will be redirected to a file specified with `:file'.
16434 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
16435 cue to call_process_cleanup not to close that handle.
16437 2011-05-07 Ben Key <bkey76@gmail.com>
16439 * makefile.w32-in: The bootstrap-temacs rule now makes use of
16440 one of two shell specific rules, either bootstrap-temacs-CMD or
16441 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
16442 to the previous implementation of the bootstrap-temacs rule.
16443 The bootstrap-temacs-CMD rule is similar to the previous
16444 implementation of the bootstrap-temacs rule except that it
16445 makes use of the ESC_CFLAGS variable instead of the CFLAGS
16448 These changes, along with some changes to nt/configure.bat,
16449 nt/gmake.defs, and nt/nmake.defs, are required to extend my
16450 earlier fix to add support for --cflags and --ldflags options
16451 that include quotes so that it works whether make uses cmd or
16454 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
16456 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
16457 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
16459 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
16460 a string. Handle both cases.
16461 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
16462 (Fdbus_register_method): Use Qinvalid_function.
16464 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
16466 * makefile.w32-in: Update dependencies.
16467 (LISP_H): Add inttypes.h and stdin.h.
16468 (PROCESS_H): Add unistd.h.
16470 2011-05-06 Eli Zaretskii <eliz@gnu.org>
16472 * lread.c: Include limits.h (fixes the MS-Windows build broken by
16473 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
16475 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
16477 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
16479 * term.c (vfatal): Remove stray call to va_end.
16480 It's not needed and the C Standard doesn't allow it here anyway.
16482 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
16483 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
16485 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
16488 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
16490 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
16492 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
16494 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
16496 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
16498 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
16499 * charset.c (Fdefine_charset_internal): Don't initialize
16500 charset.code_space[15]. The value was garbage, on hosts with
16501 32-bit int (Bug#8600).
16503 * lread.c (read_integer): Be more consistent with string-to-number.
16504 Use string_to_number to do the actual conversion; this avoids
16505 rounding errors and fixes some other screwups. Without this fix,
16506 for example, #x1fffffffffffffff was misread as -2305843009213693952.
16507 (digit_to_number): Move earlier, for benefit of read_integer.
16508 Return -1 if the digit is out of range for the base, -2 if it is
16509 not a digit in any supported base. (Bug#8602)
16511 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
16513 * dispnew.c (scrolling_window): Return 1 if we scrolled,
16514 to match comment at start of function. This also removes a
16515 GCC warning about overflow in a 32+64-bit port.
16517 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
16519 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
16520 Reported by Stefan Monnier in
16521 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
16522 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
16523 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
16525 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
16526 (EMACS_UINTPTR): Likewise, with uintptr_t.
16528 * lisp.h: Prefer 64-bit EMACS_INT if available.
16529 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
16530 on 32-bit hosts that have 64-bit int, so that they can access
16532 However, temporarily disable this change unless the temporary
16533 symbol WIDE_EMACS_INT is defined.
16535 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
16537 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
16538 This removes an assumption that EMACS_INT and long are the same
16539 width as pointers. The assumption is true for Emacs porting targets
16540 now, but we want to make other targets possible.
16541 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
16542 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
16543 In the rest of the code, change types of integers that hold casted
16544 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
16545 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
16546 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
16547 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
16548 No need to cast type when ORing.
16549 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
16550 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
16551 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
16552 assume EMACS_INT is the same width as char *.
16553 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
16554 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
16555 Remove no-longer-needed casts.
16556 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
16557 (xg_tool_bar_help_callback, xg_make_tool_item):
16558 Use EMACS_INTPTR to hold an integer
16559 that will be cast to void *; this can avoid a GCC warning
16560 if EMACS_INT is not the same width as void *.
16561 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
16562 * xdisp.c (display_echo_area_1, resize_mini_window_1):
16563 (current_message_1, set_message_1):
16564 Use a local to convert to proper width without a cast.
16565 * xmenu.c (dialog_selection_callback): Likewise.
16567 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
16568 Also, don't assume VALBITS / RAND_BITS is less than 5,
16569 and don't rely on undefined behavior when shifting a 1 left into
16571 * lisp.h (get_random): Change signature to match.
16573 * lread.c (hash_string): Use size_t, not int, for hash computation.
16574 Normally we prefer signed values; but hashing is special, because
16575 it's better to use unsigned division on hash table sizes so that
16576 the remainder is nonnegative. Also, size_t is the natural width
16577 for hashing into memory. The previous code used 'int', which doesn't
16578 retain enough info to hash well into very large tables.
16579 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
16581 * dbusbind.c: Don't possibly lose pointer info when converting.
16582 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
16583 Use XPNTR rather than XHASH, so that the high-order bits of
16584 the pointer aren't lost when converting through void *.
16586 * eval.c (Fautoload): Don't double-shift a pointer.
16588 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
16590 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
16592 * gnutls.c (DEF_GNUTLS_FN):
16593 * image.c (DEF_IMGLIB_FN): Make function pointers static.
16595 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
16597 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
16600 2011-05-05 Eli Zaretskii <eliz@gnu.org>
16602 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
16603 New version that can reserve upto 2GB of heap space.
16605 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
16607 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
16609 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
16611 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
16612 `gnutls_certificate_set_x509_key_file'.
16614 2011-05-05 Juanma Barranquero <lekktu@gmail.com>

16617 Update dependencies.
16619 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
16621 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
16622 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
16623 Remove unused parameter `fildes'.
16624 * process.c (read_process_output, send_process): Don't pass it.
16626 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
16628 Fix previous change: the library cache is defined in w32.c.
16629 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
16630 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
16632 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
16634 Implement dynamic loading of GnuTLS on Windows.
16636 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
16637 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
16638 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
16641 * gnutls.c (Qgnutls_dll): Define.

16649 (emacs_gnutls_write, emacs_gnutls_read)
16650 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
16651 (Fgnutls_available_p): New function.
16652 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.

16662 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
16664 * w32.c (QCloaded_from, Vlibrary_cache): Define.
16665 (w32_delayed_load): Move from image.c. When loading a library, record
16666 its filename in the :loaded-from property of the library id.
16667 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
16668 Initialize and staticpro them.
16669 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
16671 * process.c: Include lisp.h before w32.h, not after.
16672 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
16673 instead of gnutls_record_check_pending.
16675 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
16677 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
16679 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
16680 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
16683 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
16685 * xterm.c (x_set_frame_alpha): Do not set property on anything
16686 else than FRAME_X_OUTER_WINDOW (Bug#8608).
16688 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
16690 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
16692 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
16694 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
16695 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)

16709 (wait_for_termination, interruptible_wait_for_termination):
16710 Move after wait_for_termination_1.
16712 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
16714 * sysdep.c (interruptible_wait_for_termination): New function
16715 which is like wait_for_termination, but allows keyboard
16718 * callproc.c (Fcall_process): Add (:file "file") as an option for
16720 (Fcall_process_region): Ditto.
16722 2011-04-30 Eli Zaretskii <eliz@gnu.org>
16724 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
16725 rather than `XVECTOR (FOO)->size'.
16727 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
16728 inttypes.h, as a gnulib replacement is used if it not available in
16731 2011-04-21 Eli Zaretskii <eliz@gnu.org>
16733 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
16734 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
16735 of MOST_POSITIVE_FIXNUM. (Bug#8528)
16737 * coding.c (coding_alloc_by_realloc): Error out if destination
16738 will grow beyond MOST_POSITIVE_FIXNUM.
16739 (decode_coding_emacs_mule): Abort if there isn't enough place in
16740 charbuf for the composition carryover bytes. Reserve an extra
16741 space for up to 2 characters produced in a loop.
16742 (decode_coding_iso_2022): Abort if there isn't enough place in
16743 charbuf for the composition carryover bytes.
16745 2011-04-21 Eli Zaretskii <eliz@gnu.org>
16747 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
16748 aborting when %lld or %lll format is passed.
16749 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
16750 %llo or %llx format is passed. (Bug#8545)
16752 * window.c (window_scroll_line_based): Use a marker instead of
16753 simple variables to record original value of point. (Bug#7952)
16755 * doprnt.c (doprnt): Fix the case where a multibyte sequence
16756 produced by %s or %c overflows available buffer space. (Bug#8545)
16758 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
16760 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
16761 (SIZE_MAX): Move defn after all includes, as they might #define it.
16763 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
16765 * w32.c (init_environment): Warn about defaulting HOME to C:\.

16769 * keyboard.c (Qdelayed_warnings_hook): Define.
16770 (command_loop_1): Run `delayed-warnings-hook'
16771 if Vdelayed_warnings_list is non-nil.
16772 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
16773 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
16775 2011-04-28 Eli Zaretskii <eliz@gnu.org>
16777 * doprnt.c (doprnt): Don't return value smaller than the buffer
16778 size if the message was truncated. (Bug#8545).
16780 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
16782 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
16783 (Fx_window_property): #if-0 the whole functions, not just the bodies.
16785 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
16787 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
16789 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
16791 * makefile.w32-in: Update dependencies.
16793 2011-04-27 Eli Zaretskii <eliz@gnu.org>
16795 Improve `doprnt' and its usage. (Bug#8545)
16796 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
16797 `format_end'. Remove support for %l as a conversion specifier.
16798 Don't use xrealloc. Improve diagnostics when the %l size modifier
16799 is used. Update the commentary.
16801 * eval.c (verror): Simplify calculation of size_t.
16803 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
16806 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
16808 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
16811 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
16813 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
16814 This makes this file independent of the recent pseudovector change.
16816 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
16818 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
16820 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
16821 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
16822 Remove unused local.
16823 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
16825 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
16826 GCC 4.6.0 optimizes based on type-based alias analysis.
16827 For example, if b is of type struct buffer * and v of type struct
16828 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
16829 != &v->size, and therefore "v->size = 1; b->size = 2; return
16830 v->size;" must therefore return 1. This assumption is incorrect
16831 for Emacs, since it type-puns struct Lisp_Vector * with many other
16832 types. To fix this problem, this patch adds a new type struct
16833 vectorlike_header that documents the constraints on layout of vectors
16834 and pseudovectors, and helps optimizing compilers not get fooled
16835 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
16836 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
16837 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
16839 (XSETPVECTYPE): Rewrite in terms of new macro.
16840 (XSETPVECTYPESIZE): New macro, specifying both type and size.
16841 This is a bit clearer, and further avoids the possibility of
16842 undesirable aliasing.
16843 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
16844 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
16845 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
16846 since Lisp_Subr is a special case (no "next" field).
16847 (ASIZE): Now uses header.size rather than size.
16848 All previous uses of XVECTOR (foo)->size replaced to use this macro,
16849 to avoid the hassle of writing XVECTOR (foo)->header.size.
16850 (struct vectorlike_header): New type.
16851 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
16852 object, to help avoid aliasing.
16853 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
16854 (SUBRP): Likewise, since Lisp_Subr is a special case.
16855 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
16856 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
16857 (struct Lisp_Hash_Table): Combine first two members into a single
16858 struct vectorlike_header member. All uses of "size" and "next" members
16859 changed to be "header.size" and "header.next".
16860 * buffer.h (struct buffer): Likewise.
16861 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
16862 * frame.h (struct frame): Likewise.
16863 * process.h (struct Lisp_Process): Likewise.
16864 * termhooks.h (struct terminal): Likewise.
16865 * window.c (struct save_window_data, struct saved_window): Likewise.
16866 * window.h (struct window): Likewise.
16867 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
16868 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
16869 * buffer.c (init_buffer_once): Likewise.
16870 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
16872 * process.c (Fformat_network_address): Use local var for size,
16875 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
16877 Make the Lisp reader and string-to-float more consistent (Bug#8525)
16878 * data.c (atof): Remove decl; no longer used or needed.
16879 (digit_to_number): Move to lread.c.
16880 (Fstring_to_number): Use new string_to_number function, to be
16881 consistent with how the Lisp reader treats infinities and NaNs.
16882 Do not assume that floating-point numbers represent EMACS_INT
16883 without losing information; this is not true on most 64-bit hosts.
16884 Avoid double-rounding errors, by insisting on integers when
16885 parsing non-base-10 numbers, as the documentation specifies.
16886 * lisp.h (string_to_number): New decl, replacing ...
16887 (isfloat_string): Remove.
16888 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
16889 (read1): Do not accept +. and -. as integers; this
16890 appears to have been a coding error. Similarly, do not accept
16891 strings like +-1e0 as floating point numbers. Do not report
16892 overflow for integer overflows unless the base is not 10 which
16893 means we have no simple and reliable way to continue.
16894 Break out the floating-point parsing into a new
16895 function string_to_number, so that Fstring_to_number parses
16896 floating point numbers consistently with the Lisp reader.
16897 (digit_to_number): Move here from data.c. Make it static inline.
16898 (E_CHAR, EXP_INT): Remove, replacing with ...
16899 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
16900 (string_to_number): New function, replacing isfloat_string.
16901 This function checks for valid syntax and produces the resulting
16902 Lisp float number too. Rework it so that string-to-number
16903 no longer mishandles examples like "1.0e+". Use strtoumax,
16904 so that overflow for non-base-10 numbers is reported only when
16905 there's no portable and simple way to convert to floating point.
16907 * textprop.c (set_text_properties_1): Rewrite for clarity,
16908 and to avoid GCC warning about integer overflow.
16910 * intervals.h (struct interval): Use EMACS_INT for members
16911 where EMACS_UINT might cause problems. See
16912 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
16913 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
16914 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
16916 (offset_intervals): Tell GCC not to worry about length overflow
16917 when negating a negative length.
16919 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
16920 (overrun_check_free): Likewise.
16922 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
16923 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
16926 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
16927 (gnutls_make_error): Rename local to avoid shadowing.
16928 (gnutls_emacs_global_deinit): ifdef out; not used.
16929 (Fgnutls_boot): Use const for pointer to readonly storage.
16930 Comment out unused local. Fix pointer signedness problems.
16932 * lread.c (openp): Don't stuff size_t into an 'int'.
16933 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
16934 about possible signed overflow.
16936 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
16937 (GDK_KEY_g): Don't define if already defined.
16938 (xg_prepare_tooltip): Avoid pointer signedness problem.
16939 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
16941 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
16942 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
16944 * xfns.c (Fx_window_property): Simplify a bit,
16945 to make a bit faster and to avoid GCC 4.6.0 warning.
16946 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
16948 * fns.c (internal_equal): Don't assume size_t fits in int.
16950 * alloc.c (compact_small_strings): Tighten assertion a little.
16952 Replace pEd with more-general pI, and fix some printf arg casts.
16953 * lisp.h (pI): New macro, generalizing old pEd macro to other
16954 conversion specifiers. For example, use "...%"pI"d..." rather
16955 than "...%"pEd"...".
16956 (pEd): Remove. All uses replaced with similar uses of pI.
16957 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
16958 * alloc.c (check_pure_size): Don't overflow by converting size to int.
16959 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.

16961 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
16962 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
16963 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
16965 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
16966 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
16967 * print.c (safe_debug_print, print_object): Likewise.
16968 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
16970 Use pI instead of if-then-else-abort. Use %p to avoid casts,
16971 avoiding the 0 flag, which is not portable.
16972 * process.c (Fmake_network_process): Use pI to avoid cast.
16973 * region-cache.c (pp_cache): Likewise.
16974 * xdisp.c (decode_mode_spec): Likewise.
16975 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
16976 behavior on 64-bit hosts with printf arg.
16977 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
16978 (x_stop_queuing_selection_requests): Likewise.
16979 (x_get_window_property): Don't truncate byte count to an 'int'
16982 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
16983 here, since it parses constructs like leading '-' and spaces,
16984 which are not wanted; and it overflows with large numbers.
16985 Instead, simply match F[0-9]+, which is what is wanted anyway.
16987 * alloc.c: Remove unportable assumptions about struct layout.
16988 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
16989 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
16990 (allocate_vectorlike, make_pure_vector): Use the new macros,
16991 plus offsetof, to remove unportable assumptions about struct layout.
16992 These assumptions hold on all porting targets that I know of, but
16993 they are not guaranteed, they're easy to remove, and removing them
16994 makes further changes easier.
16996 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
16997 This doesn't fix a bug but makes the code clearer.
16998 (string_overrun_cookie): Now const. Use initializers that
16999 don't formally overflow signed char, to avoid warnings.
17000 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
17001 can cause Emacs to crash when string overrun checking is enabled.
17002 (allocate_buffer): Don't assume sizeof (struct buffer) is a
17003 multiple of sizeof (EMACS_INT); it need not be, if
17004 alignof(EMACS_INT) < sizeof (EMACS_INT).
17005 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
17007 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

17036 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
17037 "cast to pointer from integer of different size".
17039 Improve doprnt and its use in verror. (Bug#8545)
17040 * doprnt.c (doprnt): Document the set of format control sequences
17041 supported by the function. Use SAFE_ALLOCA instead of always
17044 * eval.c (verror): Don't limit the buffer size at size_max-1, that
17045 is one byte too soon. Don't use xrealloc; instead xfree and

17056 parameters of `gnutls-boot' and documented those parameters in the
17057 docstring. Start callback support.
17058 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
17059 unless a fatal error occurred. Call gnutls_alert_send_appropriate

17157 * callint.c (Fcall_interactively): When displaying error message
17158 about invalid control letter, pass the character's codepoint, not

17163 codepoint of an invalid character, to avoid displaying a bogus
17166 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
17167 `error', not SYMBOL_NAME itself.

17172 * charset.c (check_iso_charset_parameter): Fix incorrect argument
17173 to `error' in error message about FINAL_CHAR argument. Make sure
17174 FINAL_CHAR is a character, and use %c when it is passed as
17175 argument to `error'.
17177 2011-04-23 Eli Zaretskii <eliz@gnu.org>
17179 * s/ms-w32.h (localtime): Redirect to sys_localtime.
17181 * w32.c: Include <time.h>.

17241 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
17242 by pacifying GCC about it. Maybe it's time to retire it?
17243 * xfaces.c (USG, __TIMEVAL__): Likewise.
17245 * dispextern.h (struct redisplay_interface): Rename param
17246 to avoid shadowing.
17247 * termhooks.h (struct terminal): Likewise.

17364 * nsfont.m: Fixed bugs in ns_get_family and
17365 ns_descriptor_to_entity that were caused by using free to
17366 deallocate memory blocks that were allocated by xmalloc (via
17367 xstrdup). This caused Emacs to crash when compiled with
17368 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
17369 --enable-checking=xmallocoverrun). xfree is now used to
17370 deallocate these memory blocks.
17372 2011-04-15 Paul Eggert <eggert@cs.ucla.edu>
17374 * sysdep.c (emacs_read): Remove unnecessary check vs MAX_RW_COUNT.

17384 (emacs_read, emacs_write): Remove check for negative size, as the
17385 Emacs source code has been audited now.
17386 * sysdep.c (MAX_RW_COUNT): New macro, to work around kernel bugs.
17387 (emacs_read, emacs_write): Use it.
17388 * process.c (send_process): Adjust to the new signatures of
17389 emacs_write and emacs_gnutls_write. Do not attempt to store
17390 a byte offset into an 'int'; it might overflow.
17391 See http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00483.html

17415 * font.c (Qopentype): Don't make static (used from w32uniscribe.c).
17417 2011-04-14 Paul Eggert <eggert@cs.ucla.edu>
17419 Improve C-level modularity by making more things 'static'.
17421 Don't publish debugger-only interfaces to other modules.

17838 2011-04-13 Eli Zaretskii <eliz@gnu.org>
17840 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
17841 when at ZV. (Bug#8487)
17843 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
17845 * charset.c (Fclear_charset_maps): Use xfree instead of free.
17847 * keyboard.c (parse_tool_bar_item): Likewise.
17848 * sound.c (sound_cleanup, alsa_close): Likewise.
17849 * termcap.c (tgetent): Likewise.
17850 * xfns.c (x_default_font_parameter): Likewise.
17851 * xsettings.c (read_and_apply_settings): Likewise.
17853 * alloc.c (overrun_check_malloc, overrun_check_realloc)
17854 (overrun_check_free): Protoize.
17856 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
17858 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
17859 since callers should never pass a negative size.
17860 Change the signature to match that of plain 'read' and 'write'; see
17861 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
17862 * lisp.h: Update prototypes of emacs_write and emacs_read.
17864 2011-04-11 Eli Zaretskii <eliz@gnu.org>
17866 * xdisp.c (redisplay_window): Don't try to determine the character
17867 position of the scroll margin if the window start point w->startp
17868 is outside the buffer's accessible region. (Bug#8468)
17870 2011-04-10 Eli Zaretskii <eliz@gnu.org>
17872 Fix write-region and its subroutines for buffers > 2GB.
17873 * fileio.c (a_write, e_write): Modify declaration of arguments and
17874 local variables to support buffers larger than 2GB.
17875 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
17877 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
17878 argument, local variables, and return value.
17880 * lisp.h: Update prototypes of emacs_write and emacs_read.
17882 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
17884 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
17886 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
17888 Fix more problems found by GCC 4.6.0's static checks.
17890 * xdisp.c (vmessage): Use a better test for character truncation.
17892 * charset.c (load_charset_map): <, not <=, for optimization,
17893 and to avoid potential problems with integer overflow.
17894 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
17895 * casetab.c (set_identity, shuffle): Likewise.
17896 * editfns.c (Fformat): Likewise.
17897 * syntax.c (skip_chars): Likewise.
17899 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
17900 This also lets GCC 4.6.0 generate slightly better loop code.
17902 * callint.c (Fcall_interactively): <, not <=, for optimization.
17903 (Fcall_interactively): Count the number of arguments produced,
17904 not the number of arguments given. This is simpler and lets GCC
17905 4.6.0 generate slightly better code.
17907 * ftfont.c: Distingish more carefully between FcChar8 and char.
17908 The previous code passed unsigned char * to a functions like
17909 strlen and xstrcasecmp that expect char *, which does not
17910 conform to the C standard.
17911 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
17912 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
17913 char * when the C standard requires it.
17915 * keyboard.c (read_char): Remove unused var.
17917 * eval.c: Port to Windows vsnprintf (Bug#8435).
17918 Include <limits.h>.
17919 (SIZE_MAX): Define if the headers do not.
17920 (verror): Do not give up if vsnprintf returns a negative count.
17921 Instead, grow the buffer. This ports to Windows vsnprintf, which
17922 does not conform to C99. Problem reported by Eli Zaretskii.
17923 Also, simplify the allocation scheme, by avoiding the need for
17924 calling realloc, and removing the ALLOCATED variable.
17926 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
17928 Remove invocations of doprnt, as Emacs now uses vsnprintf.
17929 But keep the doprint source code for now, as we might revamp it
17930 and use it again (Bug#8435).
17931 * lisp.h (doprnt): Remove.
17932 * Makefile.in (base_obj): Remove doprnt.o.
17933 * deps.mk (doprnt.o): Remove.
17935 error: Print 32- and 64-bit integers portably (Bug#8435).
17936 Without this change, on typical 64-bit hosts error ("...%d...", N)
17937 was used to print both 32- and 64-bit integers N, which relied on
17938 undefined behavior.
17939 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
17940 * lisp.h (error, verror): Mark as printf-like functions.
17941 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
17942 Report overflow in size calculations when allocating printf buffer.
17943 Do not truncate output string at its first null byte.
17944 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
17945 Truncate the output at a character boundary, since vsnprintf does not
17947 * charset.c (check_iso_charset_parameter): Convert internal
17948 character to string before calling 'error', since %c now has the
17950 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
17951 overflow when computing char to be passed to 'error'. Do not
17952 pass Lisp_Object to 'error'; pass the integer instead.
17953 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
17954 formatted with plain %d.
17956 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
17958 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
17960 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
17962 * xterm.c (x_catch_errors): Remove duplicate declaration.
17964 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
17966 * xdisp.c, lisp.h (message_nolog): Remove; unused.
17968 2011-04-10 Jim Meyering <meyering@redhat.com>
17970 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
17971 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
17972 return ssize_t not "int", and use size_t as the buffer length.
17973 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
17974 * gnutls.h: Update declarations.
17975 * process.c (read_process_output): Use ssize_t, to match.
17976 (send_process): Likewise.
17978 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
17980 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
17982 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
17984 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
17985 Use unsigned char, to match FcChar8 type definition.
17987 * xterm.c (handle_one_xevent):
17988 * xmenu.c (create_and_show_popup_menu):
17989 * xselect.c (x_decline_selection_request)
17990 (x_reply_selection_request): Avoid type-punned deref of X events.
17992 2011-04-09 Eli Zaretskii <eliz@gnu.org>
17994 Fix some uses of `int' instead of EMACS_INT.
17995 * search.c (string_match_1, fast_string_match)
17996 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
17997 (scan_buffer, find_next_newline_no_quit)
17998 (find_before_next_newline, search_command, Freplace_match)
17999 (Fmatch_data): Make some `int' variables be EMACS_INT.
18001 * xdisp.c (display_count_lines): 3rd argument and return value now
18002 EMACS_INT. All callers changed.
18003 (pint2hrstr): Last argument is now EMACS_INT.
18005 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
18006 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
18007 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
18008 (decode_coding_utf_16, decode_coding_emacs_mule)
18009 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
18010 (decode_coding_ccl, decode_coding_charset)
18011 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
18012 (decode_coding_iso_2022, decode_coding_emacs_mule)
18013 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
18014 <char_offset, last_offset>: Declare EMACS_INT.
18015 (encode_coding_utf_8, encode_coding_utf_16)
18016 (encode_coding_emacs_mule, encode_invocation_designation)
18017 (encode_designation_at_bol, encode_coding_iso_2022)
18018 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
18019 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
18021 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
18022 (encode_invocation_designation): Last argument P_NCHARS is now
18024 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
18025 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
18027 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
18030 * ccl.c (Fccl_execute_on_string): Declare some variables
18033 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
18035 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
18037 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
18039 * process.c (Fformat_network_address): Doc fix.
18041 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
18043 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
18045 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
18047 * keyboard.c (read_char): Call Lisp function help-form-show,
18048 instead of using internal_with_output_to_temp_buffer.
18049 (Qhelp_form_show): New var.
18050 (syms_of_keyboard): Use DEFSYM macro.
18052 * print.c (internal_with_output_to_temp_buffer): Function deleted.
18054 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
18056 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
18058 * process.c (Flist_processes): Remove to Lisp.
18059 (list_processes_1): Delete.
18061 2011-04-06 Eli Zaretskii <eliz@gnu.org>
18063 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
18065 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
18067 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
18069 Fix more problems found by GCC 4.6.0's static checks.
18071 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
18073 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
18075 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
18077 * xdisp.c (vmessage): Mark as a printf-like function.
18079 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
18081 * sound.c (sound_warning): Don't crash if arg contains a printf format.
18083 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
18084 printf-like functions.
18085 (tiff_load): Add casts to remove these marks before passing them
18086 to system-supplied API.
18088 * eval.c (Fsignal): Remove excess argument to 'fatal'.
18090 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
18091 This avoids several warnings with gcc -Wstrict-overflow.
18092 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
18093 directly, rather than having caller test rule sign. This avoids
18094 some unnecessary tests.
18095 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
18096 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
18097 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
18099 * xfont.c (xfont_text_extents): Remove var that was set but not used.
18100 (xfont_open): Avoid unnecessary tests.
18102 * composite.c (composition_gstring_put_cache): Use unsigned integer.
18104 * composite.h, composite.c (composition_gstring_put_cache):
18105 Use EMACS_INT, not int, for length.

18108 breaking out part of COMPOSITION_DECODE_RULE.
18109 (COMPOSITION_DECODE_RULE): Use it.
18110 * composite.c (get_composition_id): Remove unused local vars,
18111 by using the new macro.
18113 * textprop.c (set_text_properties_1): Change while to do-while,
18114 since the condition is always true at first.
18116 * intervals.c (graft_intervals_into_buffer): Mark var as used.
18117 (interval_deletion_adjustment): Return unsigned value.
18120 * process.c (list_processes_1, create_pty, read_process_output):
18121 (exec_sentinel): Remove vars that were set but not used.
18122 (create_pty): Remove unnecessary "volatile"s.
18123 (Fnetwork_interface_info): Avoid possibility of int overflow.

18130 (update_syntax_table): Use unsigned instead of int.
18132 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
18133 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
18134 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
18136 * print.c (print_error_message): Avoid int overflow.
18138 * font.c (font_list_entities): Redo for clarity,
18139 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
18141 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
18142 (font_score): Avoid potential overflow in diff calculation.
18144 * fns.c (substring_both): Remove var that is set but not used.
18145 (sxhash): Redo loop for clarity and to avoid wraparound warning.
18147 * eval.c (funcall_lambda): Rename local to avoid shadowing.
18149 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
18150 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
18151 can always succeed if overflow has undefined behavior.
18153 * search.c (boyer_moore, wordify): Remove vars set but not used.
18154 (wordify): Omit three unnecessary tests.
18156 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
18157 All callers changed. This avoids the need for an unused var.
18159 * casefiddle.c (casify_region): Remove var that is set but not used.
18161 * dired.c (file_name_completion): Remove var that is set but not used.
18163 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
18165 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
18166 (Finsert_file_contents): Remove unnecessary code checking fd.
18168 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
18169 Check for integer overflow on size calculations.
18171 * buffer.c (Fprevious_overlay_change): Remove var that is set
18174 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
18175 Remove vars that are set but not used.
18176 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
18177 (timer_check_2): Mark vars as initialized.
18179 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
18181 * image.c (lookup_image): Remove var that is set but not used.
18182 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
18184 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
18185 that are set but not used.
18187 * xfns.c (make_invisible_cursor): Don't return garbage
18188 if XCreateBitmapFromData fails (Bug#8410).
18190 * xselect.c (x_get_local_selection, x_handle_property_notify):
18191 Remove vars that are set but not used.
18193 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
18194 (make_invisible_cursor): Initialize a possibly-uninitialized variable.

18203 (map_tty_color) [!defined MSDOS]: Likewise.
18205 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
18207 * coding.c: Remove vars that are set but not used.
18208 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
18209 All callers changed.
18210 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
18211 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
18212 (decode_coding_charset): Remove vars that are set but not used.
18214 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
18215 that is set but not used.
18217 * print.c (print_object): Remove var that is set but not used.
18219 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
18220 The gnulib version avoids calling malloc in the usual case,
18221 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
18222 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
18223 * filelock.c (current_lock_owner): Likewise.
18224 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
18225 * sysdep.c: Include allocator.h, careadlinkat.h.
18226 (emacs_no_realloc_allocator): New static constant.
18227 (emacs_readlink): New function.
18228 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
18229 ../lib/careadlinkat.h.
18231 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
18233 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
18234 first non-nil return value).
18236 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
18238 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
18239 if not defined (Bug#8403).
18241 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
18243 * xdisp.c (display_count_lines): Remove parameter `start',
18244 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
18245 (get_char_face_and_encoding): Remove parameter `multibyte_p',
18246 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

18248 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
18249 and thereabouts. All callers changed.
18250 (get_per_char_metric): Remove parameter `f', unused since
18251 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
18253 2011-04-02 Jim Meyering <meyering@redhat.com>
18255 do not dereference NULL upon failed strdup
18256 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
18257 (ns_get_family): Likewise.
18259 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
18261 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
18263 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
18265 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or

18283 (syms_of_lread): Declare `lexical-binding'.
18285 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
18287 * keyboard.c (eval_dyn): New fun.
18288 (menu_item_eval_property): Use it.
18290 * image.c (parse_image_spec): Use Ffunctionp.
18292 * fns.c (concat, mapcar1): Accept byte-code-functions.
18294 * eval.c (Fsetq): Handle lexical vars.
18295 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
18296 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
18297 (FletX, Flet): Obey lexical binding.
18298 (Fcommandp): Handle closures.
18299 (Feval): New `lexical' arg.
18300 (eval_sub): New function extracted from Feval. Use it almost
18301 everywhere where Feval was used. Look up vars in lexical env.
18303 (Ffunctionp): Move from subr.el.
18304 (Ffuncall): Handle closures.
18305 (apply_lambda): Remove `eval_flags'.
18306 (funcall_lambda): Handle closures and new byte-code-functions.
18307 (Fspecial_variable_p): New function.
18308 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
18309 but without exporting it to Lisp.
18311 * doc.c (Fdocumentation, store_function_docstring):
18312 * data.c (Finteractive_form): Handle closures.
18314 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
18317 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
18319 (exec_byte_code): New function extracted from Fbyte_code to handle new
18320 calling convention for byte-code-functions. Add new byte-codes.
18322 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
18324 * alloc.c (Fmake_symbol): Init new `declared_special' field.
18326 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
18328 * xdisp.c (redisplay_internal): Fix prototype.
18330 2011-03-31 Eli Zaretskii <eliz@gnu.org>
18332 * xdisp.c (SCROLL_LIMIT): New macro.
18333 (try_scrolling): Use it when setting scroll_limit.
18334 Limit scrolling to 100 screen lines.
18335 (redisplay_window): Even when falling back on "recentering",
18336 position point in the window according to scroll-conservatively,
18337 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
18339 (try_scrolling): When point is above the window, allow searching
18340 as far as scroll_max, or one screenful, to compute vertical
18341 distance from PT to the scroll margin position. This prevents
18342 try_scrolling from unnecessarily failing when
18343 scroll-conservatively is set to a value slightly larger than the
18344 window height. Clean up the case of PT below the margin at bottom
18345 of window: scroll_max can no longer be INT_MAX. When aggressive
18346 scrolling is in use, don't let point enter the opposite scroll
18347 margin as result of the scroll.
18348 (syms_of_xdisp) <scroll-conservatively>: Document the
18349 threshold of 100 lines for never-recentering scrolling.
18351 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
18353 * dispextern.h (move_it_by_lines):
18354 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
18355 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
18356 (message_log_check_duplicate): Remove parameters `prev_bol' and
18357 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
18358 (redisplay_internal): Remove parameter `preserve_echo_area',
18359 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
18361 * indent.c (Fvertical_motion):
18362 * window.c (window_scroll_pixel_based, Frecenter):
18363 Don't pass `need_y_p' to `move_it_by_lines'.
18365 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
18367 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
18368 steal a few bits to be more compact.
18369 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
18370 Remove unneeded casts.
18372 * bytecode.c (Fbyte_code): CAR and CDR can GC.
18374 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
18376 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
18377 binding" message (bug#7967).
18379 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
18381 Fix more problems found by GCC 4.6.0's static checks.
18383 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
18384 Remove unused local var.
18386 * editfns.c (Fmessage_box): Remove unused local var.
18388 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
18389 (note_mode_line_or_margin_highlight, note_mouse_highlight):
18390 Omit unused local vars.
18391 * window.c (shrink_windows): Omit unused local var.
18392 * menu.c (digest_single_submenu): Omit unused local var.
18393 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
18394 Omit unused local var.
18396 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
18397 Don't assume string length fits in int.
18398 (keyremap_step, read_key_sequence): Use size_t for sizes.
18399 (read_key_sequence): Don't check last_real_key_start redundantly.
18401 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
18402 instead of alloca (Bug#8344).
18404 * eval.c (Fbacktrace): Don't assume nargs fits in int.
18405 (Fbacktrace_frame): Don't assume nframes fits in int.
18407 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
18409 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
18412 * term.c (produce_glyphless_glyph): Remove unnecessary test.
18414 * cm.c (calccost): Turn while-do into do-while, for clarity.
18416 * keyboard.c (syms_of_keyboard): Use the same style as later
18417 in this function when indexing through an array. This also
18418 works around GCC bug 48267.
18420 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
18422 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
18424 * chartab.c (sub_char_table_ref_and_range): Redo for slight
18425 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
18427 * keyboard.c, keyboard.h (num_input_events): Now size_t.
18428 This avoids undefined behavior on integer overflow, and is a bit
18429 more convenient anyway since it is compared to a size_t variable.
18431 Variadic C functions now count arguments with size_t, not int.
18432 This avoids an unnecessary limitation on 64-bit machines, which
18433 caused (substring ...) to crash on large vectors (Bug#8344).
18434 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
18435 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
18436 All variadic functions and their callers changed accordingly.
18437 (struct gcpro.nvars): Now size_t, not int. All uses changed.

18439 * editfns.c (general_insert_function): Likewise.
18440 * eval.c (struct backtrace.nargs, interactive_p)
18441 (internal_condition_case_n, run_hook_with_args, apply_lambda)
18442 (funcall_lambda, mark_backtrace): Likewise.
18443 * fns.c (concat): Likewise.
18444 * frame.c (x_set_frame_parameters): Likewise.
18445 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
18446 0 if not found, not -1. All callers changed.
18448 * alloc.c (garbage_collect): Don't assume stack size fits in int.
18449 (stack_copy_size): Now size_t, not int.
18450 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
18452 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
18454 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
18455 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
18456 All callers changed.
18458 * lisp.h (multibyte_char_to_unibyte):
18459 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
18460 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
18461 * character.h (CHAR_TO_BYTE8):
18462 * cmds.c (internal_self_insert):
18463 * editfns.c (general_insert_function):
18464 * keymap.c (push_key_description):
18465 * search.c (Freplace_match):
18466 * xdisp.c (message_dolog, set_message_1): All callers changed.
18468 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
18470 * keyboard.c (safe_run_hook_funcall): New function.
18471 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
18472 don't set the hook to nil, but remove the offending function instead.
18473 (Qcommand_hook_internal): Remove, unused.
18474 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
18475 Vcommand_hook_internal.
18477 * eval.c (enum run_hooks_condition): Remove.
18478 (funcall_nil, funcall_not): New functions.
18479 (run_hook_with_args): Call each function through a `funcall' argument.
18480 Remove `cond' argument, now redundant.
18481 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
18482 (Frun_hook_with_args_until_failure): Adjust accordingly.
18483 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
18485 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
18487 * dispextern.h (string_buffer_position): Remove declaration.
18489 * print.c (strout): Remove parameter `multibyte', unused since
18490 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
18492 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
18493 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
18494 All callers changed.
18496 * w32.c (_wsa_errlist): Use braces for struct initializers.
18498 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
18499 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
18500 All callers changed.
18501 (string_buffer_position): Likewise. Also, make static (it's never
18502 used outside xdisp.c).
18503 (cursor_row_p): Remove parameter `w', unused since
18504 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.

18506 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
18507 All callers changed.
18509 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
18511 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.
18513 2011-03-27 Anders Lindgren <andlind@gmail.com>
18515 * nsterm.m (ns_menu_bar_is_hidden): New variable.
18516 (ns_constrain_all_frames, ns_menu_bar_should_be_hidden)
18517 (ns_update_auto_hide_menu_bar): New functions.
18518 (ns_update_begin): Call ns_update_auto_hide_menu_bar.

18522 (syms_of_nsterm): DEFVAR ns-auto-hide-menu-bar, init to Qnil.
18524 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
18526 * nsmenu.m (runDialogAt): Remove argument to timer_check.
18528 2011-03-27 Glenn Morris <rgm@gnu.org>
18530 * syssignal.h: Replace RETSIGTYPE with void.
18531 * atimer.c, data.c, dispnew.c, emacs.c, floatfns.c, keyboard.c:
18532 * keyboard.h, lisp.h, process.c, sysdep.c, xterm.c:
18533 Replace SIGTYPE with void everywhere.
18534 * s/usg5-4-common.h (SIGTYPE): Remove definition.
18535 * s/template.h (SIGTYPE): Remove commented out definition.
18537 2011-03-26 Eli Zaretskii <eliz@gnu.org>
18539 * xdisp.c (redisplay_window): Don't check buffer's clip_changed
18540 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
18542 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
18544 * w32.c (read_unc_volume): Use parameter `henum', instead of
18545 global variable `wget_enum_handle'.
18547 * keymap.c (describe_vector): Remove parameters `indices' and
18548 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.
18549 (describe_map, Fdescribe_vector): Adjust calls to `describe_vector'.
18551 * keyboard.h (timer_check, show_help_echo): Remove unused parameters.
18553 * keyboard.c (timer_check): Remove parameter `do_it_now',
18554 unused since 1996-04-12T06:01:29Z!rms@gnu.org.
18555 (show_help_echo): Remove parameter `ok_to_overwrite_keystroke_echo',
18556 unused since 2008-04-19T19:30:53Z!monnier@iro.umontreal.ca.
18558 * keyboard.c (read_char):
18559 * w32menu.c (w32_menu_display_help):
18560 * xmenu.c (show_help_event, menu_help_callback):
18561 Adjust calls to `show_help_echo'.
18563 * gtkutil.c (xg_maybe_add_timer):
18564 * keyboard.c (readable_events):
18565 * process.c (wait_reading_process_output):
18566 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
18568 * insdel.c (adjust_markers_gap_motion):
18569 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.
18570 (gap_left, gap_right): Don't call it.
18572 2011-03-25 Chong Yidong <cyd@stupidchicken.com>
18574 * xdisp.c (handle_fontified_prop): Discard changes to clip_changed
18575 incurred during fontification.

18616 2011-03-24 Juanma Barranquero <lekktu@gmail.com>
18618 * w32term.c (x_set_glyph_string_clipping):
18619 Don't pass uninitialized region to CombineRgn.
18621 2011-03-23 Juanma Barranquero <lekktu@gmail.com>
18623 * w32fns.c (x_set_menu_bar_lines): Remove unused variable `olines'.
18624 (w32_wnd_proc): Pass NULL to Windows API, not uninitialized buffer.
18625 (Fx_close_connection): Remove unused variable `i'.
18627 * w32font.c (w32font_draw): Return number of glyphs.
18628 (w32font_open_internal): Remove unused variable `i'.

18641 (uniscribe_font_driver): Add missing initializers.
18643 2011-03-23 Julien Danjou <julien@danjou.info>
18645 * term.c (Fsuspend_tty, Fresume_tty):
18646 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
18647 * window.c (temp_output_buffer_show):
18648 * insdel.c (signal_before_change):
18649 * frame.c (Fhandle_switch_frame):
18650 * fileio.c (Fdo_auto_save):
18651 * emacs.c (Fkill_emacs):
18652 * editfns.c (save_excursion_restore):
18653 * cmds.c (internal_self_insert):
18654 * callint.c (Fcall_interactively):
18655 * buffer.c (Fkill_all_local_variables):
18656 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
18658 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
18659 unconditionally since it does the check itself.
18661 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
18663 Fix more problems found by GCC 4.5.2's static checks.
18665 * coding.c (encode_coding_raw_text): Avoid unnecessary test
18666 the first time through the loop, since we know p0 < p1 then.
18667 This also avoids a gcc -Wstrict-overflow warning.
18669 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
18670 leading to a memory leak, possible in functions like
18671 load_charset_map_from_file that can allocate an unbounded number
18672 of objects (Bug#8318).
18674 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
18675 that could (at least in theory) be that large.
18677 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
18678 This is less likely to overflow, and avoids undefined behavior if
18679 overflow does occur. All callers changed. Use strtoul to scan
18680 for the unsigned long integer.
18681 (pint2hrstr): Simplify and tune code slightly.
18682 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
18684 * scroll.c (do_scrolling): Work around GCC bug 48228.
18685 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
18687 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
18688 This also avoids a warning with gcc -Wstrict-overflow.
18689 (validate_x_resource_name): Simplify count usage.
18690 This also avoids a warning with gcc -Wstrict-overflow.
18692 * fileio.c (Fcopy_file): Report error if fchown or fchmod
18695 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
18697 * process.c (Fmake_network_process): Use socklen_t, not int,
18698 where POSIX says socklen_t is required in portable programs.
18699 This fixes a porting bug on hosts like 64-bit HP-UX, where
18700 socklen_t is wider than int (Bug#8277).
18701 (Fmake_network_process, server_accept_connection):
18702 (wait_reading_process_output, read_process_output):
18705 * process.c: Rename or move locals to avoid shadowing.
18706 (list_processes_1, Fmake_network_process):
18707 (read_process_output_error_handler, exec_sentinel_error_handler):
18708 Rename or move locals.
18709 (Fmake_network_process): Define label "retry_connect" only if needed.
18710 (Fnetwork_interface_info): Fix pointer signedness.
18711 (process_send_signal): Add cast to avoid pointer signedness problem.
18712 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
18713 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
18715 Make tparam.h and terminfo.c consistent.
18716 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
18717 Include tparam.h instead, since it declares them.
18718 * cm.h (PC): Remove extern decl; tparam.h now does this.

18777 clobbering (Bug#8298).
18778 * sysdep.c (sys_subshell): Likewise.
18779 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
18781 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
18782 This should get cleaned up, so that child_setup has the
18783 same signature on all platforms.
18785 * callproc.c (call_process_cleanup): Now static.
18786 (relocate_fd): Rename locals to avoid shadowing.
18788 2011-03-22 Chong Yidong <cyd@stupidchicken.com>

18947 (Fmemory_limit): Cast sbrk's returned value to char *.
18949 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this

18955 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
18956 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
18957 to use the following functions instead of these macros.
18958 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
18959 EMACS_INT, since callers assume the returned value fits in int.
18960 (upcase1): Likewise, for UPCASE_TABLE.
18961 (uppercasep, lowercasep, upcase): New static inline functions.
18962 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

18972 (regex_compile, re_match_2_internal): Mark locals as initialized.
18973 (RETALLOC_IF): Define only if needed.
18974 (WORDCHAR_P): Likewise. This one is never needed, but is used
18975 only in a comment talking about a compiler bug, so put inside
18976 the #if 0 of that comment.
18977 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
18978 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

19005 New macros, so that the caller can use some names other than
19006 gcpro1, gcpro2, etc.
19007 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
19009 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
19010 argument, for consistency with GCPRO2_VAR, etc: it is now the
19011 prefix of the variable, not the variable itself. All uses
19013 * dired.c (directory_files_internal, file_name_completion):
19014 Rename locals to avoid shadowing.
19016 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
19017 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
19018 dired.c's scmp function, had undefined behavior.
19019 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
19020 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
19021 * buffer.h: ... to here, because these macros use current_buffer,
19022 and the new implementation with inline functions needs to have
19023 current_buffer in scope now, rather than later when the macros
19025 (downcase, upcase1): New static inline functions.
19026 (DOWNCASE, UPCASE1): Reimplement using these functions.
19027 This avoids undefined behavior in expressions like
19028 DOWNCASE (x) == DOWNCASE (y), which previously suffered
19029 from race conditions in accessing the global variables
19030 case_temp1 and case_temp2.
19031 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
19032 * lisp.h (case_temp1, case_temp2): Remove their decls.
19033 * character.h (ASCII_CHAR_P): Move from here ...
19034 * lisp.h: ... to here, so that the inline functions mentioned
19035 above can use them.

19042 (file_name_as_directory): Use const pointers when appropriate.
19043 (Fexpand_file_name): Likewise. In particular, newdir might
19044 point at constant storage, so make it a const pointer.

19046 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
19048 (Fset_file_times, Finsert_file_contents, auto_save_error):

19053 to avoid shadowing.
19055 * marker.c (bytepos_to_charpos): Remove; unused.
19057 * lisp.h (verify_bytepos, count_markers): New decls,
19058 so that gcc does not warn that these functions aren't declared.

19061 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
19062 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
19063 (copy_text): Remove unused local var.

19068 * buffer.c (fix_overlays_before): Mark locals as initialized.
19069 (fix_start_end_in_overlays): Likewise. This function should be
19070 simplified by using pointers-to-pointers, but that's a different
19072 (switch_to_buffer_1): Now static.
19073 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
19074 (report_overlay_modification): Rename locals to avoid shadowing.

19079 to suppress a gcc -Wclobbered warning that does not seem to be right.
19080 (MAXPATHLEN): Define only if needed.
19082 * process.c (serial_open, serial_configure): Move decls from here ...
19083 * systty.h: ... to here, so that they can be checked.
19085 * fns.c (get_random, seed_random): Move extern decls from here ...
