24 (xmenu_show, xdialog_show):
25 Use bool for booleans.
26 * lread.c (safe_to_load_version): Rename from safe_to_load_p,
27 as it's not a predicate. All uses changed. Omit unnecessary
30 2012-10-11 Dmitry Antipov <dmantipov@yandex.ru>
32 * editfns.c (save_excursion_save): Use nil if mark points to nowhere.

77 * keyboard.c (timers_run, swallow_events)
78 (detect_input_pending_run_timers):
79 * process.c (wait_reading_process_output):
80 Use unsigned for counter where wraparound-on-overflow is desired,
81 since unsigned is guaranteed to have that behavior and signed is not.
82 (read_char): Use ptrdiff_t for string length.
83 (get_input_pending): Remove first argument, since it was always
84 the same pointer-to-int (now pointer-to-boolean) &input_pending,
85 and behave as if it had that value. Return new value of
86 input_pending. All callers changed.
87 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
88 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's
90 * keymap.c (push_key_description): Omit last arg, which was always 1.
93 * regex.c (immediate_quit) [emacs]: Remove duplicate decl.
95 2012-10-10 Juanma Barranquero <lekktu@gmail.com>

104 initializer for PVEC_NORMAL_VECTOR.
106 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
108 Clean out old termopts cruft.
109 * termopts.h (flow_control, meta_key): Remove unused decls.
110 * dispnew.c, indent.c, nsterm.m, term.c, xsettings.c, xsmfns.c:
111 Don't include termopts.h.
113 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>
115 * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers.
117 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
119 * commands.h (immediate_quit): Remove duplicate decl.
121 2012-10-09 Jan Djärv <jan.h.d@swipnet.se>

126 (syms_of_nsfont): Remove initialization of Vfonts_in_cache
128 2012-10-09 Eli Zaretskii <eliz@gnu.org>
130 * w32fns.c (w32_last_error): Change the return value to DWORD, to
131 match what GetLastError returns. Explain why the function is
134 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
135 'is_tooltip_frame', to avoid confusion with its global namesake.
137 2012-10-08 Daniel Colascione <dancol@dancol.org>
139 * xdisp.c (start_hourglass): Call w32_note_current_window when
140 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
141 build that caused Emacs to display the hourglass cursor forever.
143 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
144 which is broken under remote desktop, calculate the number of
145 colors available for a display based on the display's number of
146 planes and number of bits per pixel per plane. (bug#10397).
148 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
150 * nsfont.m (Vfonts_in_cache): New variable.
151 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
152 are used. Add cached fonts to Vfonts_in_cache.
153 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
155 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
157 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
159 (FONT_H): Define after FRAME_H.
160 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
163 * w32term.c: Remove leftover declaration of keyboard_codepage.
165 2012-10-08 Eli Zaretskii <eliz@gnu.org>
167 * makefile.w32-in (FONT_H): Add $(FRAME_H).
168 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
169 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
170 (GLOBAL_SOURCES): Add cygw32.c.
171 ($(BLD)/unexw32.$(O)):
173 ($(BLD)/w32console.$(O)):
174 ($(BLD)/w32fns.$(O)):
175 ($(BLD)/w32heap.$(O)):
176 ($(BLD)/w32menu.$(O)):
177 ($(BLD)/w32proc.$(O)): Add w32common.h.
179 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
181 (x_to_w32_color): Don't modify the argument, modify a copy instead.
183 2012-10-08 Daniel Colascione <dancol@dancol.org>
185 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
186 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
187 accidental message numbering hole. Change other messages to
190 * w32select.h (HAVE_W32SELECT): Remove.
192 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
193 w32common.h instead of w32heap.h
195 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
196 (get_allocation_unit, get_processor_type, get_w32_major_version)

198 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
199 (OS_NT, os_subtype, cache_system_info): Move declarations to
202 * w32heap.c: Include w32common.h.
203 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
204 (w32_minor_version, w32_build_number, w32_subtype): Remove
205 duplicate definitions.
207 * w32fns.c: Include w32common.h; include w32heap.h only in
210 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
211 Use `report_file_error' instead of `error' in order to better
212 inform users of what went wrong. Increase NTGUI_UNICODE file
213 dialog box file name length to 32k, the maximum allowed by the NT
216 * w32common.h: New file.
217 (ROUND_UP, ROUND_DOWN, get_page_size)
218 (get_allocation_unit, get_processor_type, get_w32_major_version)
219 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
220 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
221 (OS_NT, os_subtype, cache_system_info): Move here.
223 * unexw32.c, unexcw.c: Include w32common.h.
225 * emacs.c (main): Use (defined (WINDOWSNT) || defined
226 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
227 to call syms_of_w32select.
229 * cygw32.h: Remove obsolete EXFUN declarations.
231 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
233 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
234 of w32inevt.o from SOME_MACHINE_OBJECTS.
236 2012-10-08 Daniel Colascione <dancol@dancol.org>
238 * image.c: Permanent fix for JPEG compilation issue --- limit
239 jpeglib `boolean' redefinition to Cygwin builds.
241 2012-10-08 Eli Zaretskii <eliz@gnu.org>
243 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
245 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
248 2012-10-08 Daniel Colascione <dancol@dancol.org>
250 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
251 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
252 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
253 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
254 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
255 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
256 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
257 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
258 now a supported configuration.
260 * Makefile.in: consolidate image variables into LIBIMAGE; add
261 W32_OBJ and W32_LIBS. Compile new files.
264 (_DebPrint) declare tracing facility for W32 debugging. We need
265 to unify tracing later.
267 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
268 unconditional use of W32 Unicode functions. Cygwin runs only on
269 100% Unicode operating systems.
271 * cygw32.c: New file. Define Cygwin-specific facilities.
272 (Fcygwin_convert_path_to_windows)
273 (Fcygwin_convert_path_from_windows): New user functions for
274 accessing Cygwin path-munging routines.
276 * cygw32.h: New file.
277 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
278 UTF-16LE strings temporarily inside non-Lisp-visible string
281 (w32_strerror): Just what it says on the tin.
283 * emacs.c: Make the NS fork-then-exec code for daemon-launching
284 also run for Cygwin; both systems have the same problem with using
285 GUI facilities in a forked child. Also call syms_of_cygw32,
286 syms_of_w32select in correct places.
288 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
289 needs fork-then-exec for daemon launching.
291 * font.h: Include frame.h.
293 * image.c: Use the image library cache machinery only when we're
294 compiling for native WINDOWSNT; Cygwin can use shared libraries
295 like any other Unixlike system.
297 * keyboard.c: Clarify a comment regarding the input loop.
299 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
300 functions directly instead of trying to detect at runtime that our
301 host operating system supports them. We make this change for two
302 reasons: Cygwin lacks support for the multibyte character
303 conversion functions used by the legacy menu code, and Cygwin
304 never needs to rely on non-Unicode APIs.
306 * unexw32.c (hinst): Declare extern.
308 * w32.c: Change header order;
309 (w32_strerror): Move to w32fns.c because we need it for
310 non-WINDOWSNT builds.
312 * w32.h: Add #error macro to make sure we don't include w32.h for
313 Cygwin builds. Remove w32select declarations.
315 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
316 w32fns.c. w32console.c is WINDOWSNT-only.
318 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
319 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
321 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
322 (w32_major_version, w32_minor_version, w32_build_number)
323 (os_subtype, sound_type): Define here
324 (w32_defined_color): Make color parameter const for consistency
325 with other _defined_color functions.
326 (w32_createwindow): Unconditionally call w32_init_class instead of
327 doing so only when hprevinst is non-NULL. Plumbing hprevinst
328 through the code is complex and unnecessary because class
329 registration is practically free.
330 (w32_name_of_message): New EMACSDEBUG-only function.
331 (Fset_message_beep): Move here
332 (Fx_open_connection): Require that the display name for Windows be
333 "w32" for consistency, emacsclient disambiguation, and maybe, one
334 day, multi-window-system support.
335 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
336 Cygwin files for W32 GUI facilities, since these clearly don't
339 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
340 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
341 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
342 (w32_last_error): Remove.
344 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
346 * w32heap.c (syspage_mask): Declare here.
347 (cache_system_info): Remove.
349 * w32inevt.c (faked_key): Define globally, not statically.
350 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
351 (w32_console_toggle_lock_key): Move to w32fns.c.
353 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
355 * w32proc.c (_DebPrint): Move to w32fns.c.
356 * w32select.c: Include string.h, stdio.h for Cygwin.
357 * w32select.h: New File.
359 * w32term.c: Include io.h for non-CYGWIN builds; needed for
361 (w32_message_fd): New variable. Under Cygwin, holds the file
362 descriptor the system used to tell us about pending thread
365 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
366 that prevented compilation under non-WINDOWSNT systems.
368 (w32_initialize): Open /dev/windows and assign it to
369 w32_message_fd. Provide w32 feature.
371 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
372 (WM_EMACS_INPUT_READY): add.
373 (prepend_msg, w32_message_fd): Declare globally.
376 (keyboard_handle): Use only when WINDOWSNT.
377 (notify_msg_ready): New function. Posts a message to the main
378 thread's message queue under CYGWIN, which wakes up the main
379 thread from select(2) by making the /dev/windows file descriptor
380 ready. Under WINDOWSNT, it sets an event the same way the old
383 (post, prepend_msg): Actually call notify_msg_ready instead of
384 setting the input event directly.
386 2012-10-07 Eli Zaretskii <eliz@gnu.org>
388 * ralloc.c (relinquish): If a heap is ready to be relinquished,
389 but it still has blocs in it, don't return it to the system,
390 instead of aborting. (Bug#12402)
392 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
394 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
396 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
397 MAC_OS_X_VERSION_10_6.
398 (syms_of_nsterm): Remove comment about Panther and above for
400 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.

404 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
405 MAC_OS_X_VERSION_10_4.
407 * nsmenu.m (fillWithWidgetValue:): Remove code for <
408 MAC_OS_X_VERSION_10_2.
410 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
412 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
413 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
415 * nsterm.m (ns_in_resize): Remove (Bug#12479).
416 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
417 (ns_clear_frame, sendEvent, windowDidResize, drawRect:): Remove
419 (ns_clear_frame_area): Remove resize handle code.
421 * nsfns.m (ns_in_resize): Remove.
422 (x_set_icon_name, ns_set_name, ns_set_name_as_filename): Remove
425 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
427 Improve sys_siglist detection.
428 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
429 defined as a macro, as is done in Solaris.
430 (sys_siglist_entries): New macro.
431 (save_strsignal): Use it.
432 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
433 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
435 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
437 * nsfns.m (Fx_create_frame): Call x_default_parameter with
438 fullscreen/Fullscreen.
440 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
443 * nsterm.m (x_make_frame_visible): Check for fullscreen.
444 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
445 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
446 (windowDidResize:): Check for correct window if old style fullscreen.
447 Capitalize word in comment. Remove incorrect comment.
448 (initFrameFromEmacs:): tbar_height renamed tibar_height.
449 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
450 error in drawing background.
451 (toggleFullScreen:): Remove comment. Rearrange calls.
452 Set toolbar values to zero, save old height in tobar_height.
453 Restore tool bar height when leaving fullscreen.
454 (canBecomeMainWindow): New function.
456 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
458 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
460 2012-10-05 Eli Zaretskii <eliz@gnu.org>
462 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
464 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
465 that time stamps of directories could also be changed. Don't
466 request the too broad GENERIC_WRITE, only the more restrictive
467 FILE_WRITE_ATTRIBUTES access rights.
469 * fileio.c (Fset_file_times): Special-case ignoring errors for
470 directories only on MSDOS, not on MS-Windows.
472 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
474 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
476 2012-10-04 Eli Zaretskii <eliz@gnu.org>
478 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
479 see whether CreateFile failed.
481 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
483 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
484 to avoid similar races.
485 * keyboard.c (pending_signals): Now bool, not int.
487 Port timers to OpenBSD, plus check for timer failures.
488 OpenBSD problem reported by Han Boetes.
489 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
491 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
492 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
493 like OpenBSD, which has timer_settime but does not declare it.
494 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
495 whether to use itimerspec-related primitives. All uses of
496 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.

500 * profiler.c (handle_profiler_signal): Fix a malloc race
501 that caused Emacs to hang on Fedora 17 when profiling Lisp.
503 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>

524 Now 'static', not 'static inline'.
526 Count overruns when profiling; change units to ns.
527 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
528 Give extra weight to samples after overruns, to attempt to count
529 the time more accurately.
530 (setup_cpu_timer): Change sampling interval units from ms to ns, since
531 the underlying primitives nominally do ns.
532 (Fprofiler_cpu_start): Document the change. Mention that
533 the sampling intervals are only approximate.
535 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>

551 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
553 Fix a malloc race condition involving strsignal.
554 A signal can arrive in the middle of a malloc, and Emacs's signal
555 handler can invoke strsignal, which can invoke malloc, which is
556 not portable. This race condition bug makes Emacs hang on GNU/Linux.
557 Fix it by altering the signal handler so that it does not invoke
559 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
560 * process.c (status_message): Use const pointer, in case strsignal
561 is #defined to safe_strsignal.
562 * sysdep.c (sys_siglist, init_signals): Always define and
563 initialize a substitute sys_siglist if the system does not define
564 one, even if HAVE_STRSIGNAL.
565 (safe_strsignal): Rename from strsignal. Always define,
566 using sys_siglist. Return a const pointer.
567 * syssignal.h (safe_strsignal): New decl.
568 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
570 2012-10-01 Eli Zaretskii <eliz@gnu.org>
572 * w32proc.c (timer_loop): Fix code that waits for timer
573 expiration, to avoid high CPU usage.

577 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
578 (sweep_weak_table): Remove redundant prototypes.
580 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
582 * emacs.c: Move the inclusion of TERM_HEADER after including
583 windows.h on WINDOWSNT. This avoids compilation problems with
586 2012-10-01 Eli Zaretskii <eliz@gnu.org>
588 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
589 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
590 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
591 as the previous version used 'void *'.
593 * ralloc.c (ROUNDUP): Fix last change.
594 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
597 * w32proc.c <disable_itimers>: New static flag.
598 (init_timers): Initialize it to zero, after creating the critical
599 sections used by the timer threads.
600 (term_timers): Set to 1 before deleting the critical sections.
601 (getitimer, setitimer): If disable_itimers is non-zero, return an
602 error indication without doing anything. Reported by Fabrice
603 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
604 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
606 [!HAVE_SETITIMER]: Behave as the previous version that didn't
609 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
610 term_ntproc after all the other bookkeeping, to get timers working
613 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
615 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
616 Suggested by Juri Linkov in
617 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
619 Prefer plain 'static' to 'static inline' (Bug#12541).
620 With static functions, modern compilers inline pretty well by
621 themselves; advice from programmers often hurts as much as it helps.
622 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
623 this change shrinks the text size of the Emacs executable by 1.1%
624 without affecting CPU significantly in my benchmark.

907 Profiler improvements: more-accurate timers, overflow checks.
908 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
909 signal.h, setjmp.h. Include systime.h instead.

916 (profiler_cpu_running): Now of that enum type, not bool.
917 All uses changed to store the new value.
918 (handle_profiler_signal): Rename from sigprof_handler_1,
919 for consistency with other handlers. Do not check whether
920 cpu_log is a hash-table if garbage collecting, since it
921 doesn't matter in that case.
922 (deliver_profiler_signal): Rename from sigprof_handler,
923 for consistency with other handlers.
924 (setup_cpu_timer): New function, with much of what used to be in
925 Fprofiler_cpu_start. Check for out-of-range argument.
926 Prefer timer_settime if available, and prefer
927 thread cputime clocks, then process cputime clocks, then
928 monotonic clocks, to the old realtime clock. Use make_timeval
929 to round more-correctly when falling back to setitimer.
930 (Fprofiler_cpu_start): Use it.
931 (Fprofiler_cpu_stop): Prefer timer_settime if available.
932 Don't assume that passing NULL as the 2nd argument of setitimer

934 Ignore SIGPROF afterwards.
935 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
936 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
937 non-fatal signal handlers. Ignore SIGPROF on startup.

939 in profiler.c, since sysdep.c now uses it.
941 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.

955 * eval.c (interactive_p, Fsignal, eval_sub, Ffuncall, Fbacktrace)
956 (Fbacktrace_frame): Adjust accordingly.
958 2012-09-28 Glenn Morris <rgm@gnu.org>
960 * eval.c (Frun_hook_with_args, Frun_hook_with_args_until_success)
961 (Frun_hook_with_args_until_failure): Doc fixes.
963 2012-09-28 Eli Zaretskii <eliz@gnu.org>

979 * Makefile.in (LIB_TIMER_TIME): New macro.
981 * atimer.c (alarm_timer, alarm_timer_ok, set_alarm, init_atimer):
982 Use HAVE_TIMER_SETTIME, not SIGEV_SIGNAL, to decide whether to
985 2012-09-26 Tomohiro Matsuyama <tomo@cx4a.org>
987 * profiler.c (Fprofiler_cpu_start): Remove unnecessary flag SA_SIGINFO.

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

1002 Stefan Monnier <monnier@iro.umontreal.ca>
1003 Juanma Barranquero <lekktu@gmail.com>

1028 2012-09-25 Juanma Barranquero <lekktu@gmail.com>
1030 * makefile.w32-in ($(BLD)/callproc.$(O)): Update dependencies.
1032 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>
1034 Prefer POSIX timers if available.
1035 They avoid a race if the timer is too close to the current time.
1036 * atimer.c (alarm_timer, alarm_timer_ok) [SIGEV_SIGNAL]: New static vars.
1037 (set_alarm) [SIGEV_SIGNAL]: Use POSIX timers if available.

1054 * image.c (reset_image_types): New function.
1056 * emacs.c [WINDOWSNT] (Vlibrary_cache): Move from w32.c.

1067 * w32proc.c (sys_signal): Handle all signals defined by the
1068 MS-Windows runtime, not just SIGCHLD. Actually install the signal
1069 handlers for signals supported by Windows. Don't override
1070 term_ntproc as the handler for SIGABRT.
1071 (sigaction): Rewrite to call sys_signal instead of duplicating its
1073 (sys_kill): Improve commentary.
1075 * w32.c (term_ntproc): Accept (and ignore) one argument, for
1076 consistency with a signature of a signal handler. All callers
1078 (init_ntproc): Accept an argument DUMPING. If dumping, don't
1079 install term_ntproc as a signal handler for SIGABRT, as that
1080 should be done by the dumped Emacs.
1082 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
1084 * w32select.c (term_w32select): Protect against repeated
1085 invocation by setting clipboard_owner to NULL after calling
1088 * emacs.c (shut_down_emacs, main): Adapt the calls to init_ntproc
1089 and term_ntproc to their modified signatures.
1091 * character.c (char_string, string_char): Remove calls to
1092 MAYBE_UNIFY_CHAR. See the discussion starting at

1100 2012-09-24 Stefan Monnier <monnier@iro.umontreal.ca>
1102 * bytecode.c (exec_byte_code): Signal an error instead of aborting,
1103 when encountering an unknown bytecode.
1105 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
1107 image.c, indent.c: Use bool for booleans.
1108 * dispextern.h (struct image_type): Members valid_p, load, init
1109 now return bool, not int. All uses changed.
1110 * image.c: Omit unnecessary static decls.
1111 (x_create_bitmap_mask, x_build_heuristic_mask):
1112 Return void, not int, since callers don't care about the return value.

1145 * chartab.c (Fset_char_table_default): Obsolete function removed.
1147 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
1149 Move pid_t related decls out of lisp.h.
1150 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
1151 (interruptible_wait_for_termination):
1152 Move these decls from lisp.h to syswait.h, since they use pid_t.
1153 Needed on FreeBSD; see Herbert J. Skuhra in
1154 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
1155 * callproc.c: Include syswait.h.

1173 * nsmenu.m, w32menu.c, xmenu.c (set_frame_menubar):

1175 Use bool for boolean.
1176 * gtkutil.c (xg_update_frame_menubar):
1177 * xmenu.c (update_frame_menubar):
1178 Return void, not int, since caller ignores return value.

1182 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
1184 * makefile.w32-in (BLOCKINPUT_H): Remove.

1201 2012-09-23 Eli Zaretskii <eliz@gnu.org>
1203 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
1204 fatal_error_backtrace.
1206 * w32proc.c (sys_kill): Undo last change: don't do anything when
1207 invoked to deliver SIGABRT to our own process. This is now
1208 handled by emacs_raise.
1210 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
1212 * w32term.c (w32_read_socket): Remove leftover reference to
1213 interrupt_input_pending.
1215 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
1217 Do not use SA_NODEFER.
1218 Problem reported by Dani Moncayo in
1219 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
1221 * sysdep.c (emacs_abort): Do not reset signal handler.
1222 * emacs.c (terminate_due_to_signal): Reset signal handler here.
1223 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
1224 wanted even on POSIXish hosts, and it doesn't work on Windows.
1226 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
1228 * xterm.c (x_term_init): Call fixup_locale before and after calling
1229 gtk_init (Bug#12392).
1231 2012-09-23 Chong Yidong <cyd@gnu.org>
1233 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
1234 Vdynamic_library_alist.
1236 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
1237 (Fgnutls_available_p): Caller changed.
1239 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
1240 (Flibxml_parse_xml_region): Likewise.
1242 * dispextern.h (struct image_type): Remove arg from init function.
1244 * image.c (Finit_image_library, lookup_image_type)
1245 (define_image_type): Remove now-unneeded second arg.
1246 (init_xpm_functions, init_png_functions, init_jpeg_functions)
1247 (init_tiff_functions, init_gif_functions, init_svg_functions):
1248 Arglist and w32_delayed_load calling convention changed.
1249 (gs_type): Remove init_gs_functions; there is no such function.
1250 (valid_image_p, make_image): Fix caller to lookup_image_type.
1252 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
1254 Simplify and avoid signal-handling races (Bug#12471).
1256 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
1257 Avoid recursive loop if there's a fatal error in the function itself.
1258 * atimer.c (pending_atimers):
1259 * blockinput.h: Don't include "atimer.h"; no longer needed.
1260 (interrupt_input_pending): Remove. All uses removed.
1261 pending_signals now counts both atimers and ordinary interrupts.
1262 This is less racy than having three separate pending-signal flags.
1263 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
1265 Rename from their upper-case counterparts BLOCK_INPUT,
1266 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
1267 INPUT_BLOCKED_P, and turn into functions. All uses changed.
1268 This makes it easier to access volatile variables more accurately.
1269 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
1270 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
1271 that's more reliable if the code is buggy and sets
1272 interrupt_input_blocked to a negative value. All uses changed.
1273 * atimer.c (deliver_alarm_signal):
1274 Remove. No need to deliver this to the parent; any thread can
1275 handle this signal now. All uses replaced by underlying handler.
1276 * atimer.c (turn_on_atimers):
1277 * dispnew.c (handle_window_change_signal):
1278 * emacs.c (handle_danger_signal):
1279 * keyboard.c (kbd_buffer_get_event):
1280 Don't reestablish signal handler; not needed with sigaction.
1281 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
1283 Rework to avoid unnecessary accesses to volatile variables.
1284 (UNBLOCK_INPUT_TO): Now a function.
1285 (totally_unblock_input, unblock_input): New decls.
1286 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
1287 (init_data): Remove. Necessary stuff now done in init_signal.
1288 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
1289 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
1290 (fatal_error_code): Remove; no longer needed.
1291 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
1292 it doesn't always backtrace. All uses changed. No need to reset
1293 signal to default, since sigaction and/or die does that for us now.
1294 Use emacs_raise (FOO), not kill (getpid (), FOO).
1295 (main): Check more-accurately whether we're dumping.
1296 Move fatal-error setup to sysdep.c
1297 * floatfns.c: Do not include "syssignal.h"; no longer needed.
1298 * gtkutil.c (xg_get_file_name, xg_get_font):
1299 Remove no-longer-needed signal-mask manipulation.
1300 * keyboard.c, process.c (POLL_FOR_INPUT):
1301 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
1302 * keyboard.c (read_avail_input): Remove.
1303 All uses replaced by gobble_input.
1304 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
1305 (kbd_buffer_store_event_hold, gobble_input):
1306 (record_asynch_buffer_change) [USABLE_SIGIO]:
1307 (store_user_signal_events):
1308 No need to mess with signal mask.
1309 (gobble_input): If blocking input and there are terminals, simply
1310 set pending_signals to 1 and return. All hooks changed to not
1311 worry about whether input is blocked.
1312 (process_pending_signals): Clear pending_signals before processing
1313 them, in case a signal comes in while we're processing.
1314 By convention callers now test pending_signals before calling us.
1315 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
1316 New functions, to support changes to blockinput.h.
1317 (handle_input_available_signal): Now extern.
1318 (reinvoke_input_signal): Remove. All uses replaced by
1320 (quit_count): Now volatile, since a signal handler uses it.
1321 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
1322 All callers changed. Block SIGINT only if not already blocked.
1323 Clear sigmask reliably, even if Fsignal returns, which it can.
1324 Omit unnecessary accesses to volatile var.
1325 (quit_throw_to_read_char): No need to restore sigmask.
1326 * keyboard.c (gobble_input, handle_user_signal):
1327 * process.c (wait_reading_process_output):
1328 Call signal-handling code rather than killing ourselves.
1329 * lisp.h: Include <float.h>, for...
1330 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
1331 (pending_signals): Now volatile.
1332 (syms_of_data): Now const if IEEE floating point.
1333 (handle_input_available_signal) [USABLE_SIGIO]:
1334 (terminate_due_to_signal, record_child_status_change): New decls.
1335 * process.c (create_process): Avoid disaster if memory is exhausted
1336 while we're processing a vfork, by tightening the critical section
1338 (send_process_frame, process_sent_to, handle_pipe_signal)
1339 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
1341 (send_process): No need for setjmp/longjmp any more, since the
1342 SIGPIPE stuff is now gone. Instead, report an error if errno
1344 (record_child_status_change): Now extern. PID and W are now args.
1345 Return void, not bool. All callers changed.
1346 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
1347 Remove. All uses removed. This bug should be fixed now in a
1349 (wait_for_termination_1): Use waitpid rather than sigsuspend,
1350 and record the child status change directly. This avoids the
1351 need to futz with the signal mask.
1352 (process_fatal_action): Move here from emacs.c.
1353 (emacs_sigaction_flags): New function, containing
1354 much of what used to be in emacs_sigaction_init.
1355 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
1356 caught by emacs, to make races less likely.
1357 (deliver_process_signal): Rename from handle_on_main_thread.
1359 (BACKTRACE_LIMIT_MAX): Now at top level.
1360 (thread_backtrace_buffer, threadback_backtrace_pointers):
1362 (deliver_thread_signal, deliver_fatal_thread_signal):
1363 New functions, for more-accurate delivery of thread-specific signals.
1364 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
1365 (deliver_arith_signal): Handle in this thread, not
1366 in the main thread, since it's triggered by this thread.
1367 (maybe_fatal_sig): New function.
1368 (init_signals): New arg DUMPING so that we can be more accurate
1369 about whether we're dumping. Caller changed.
1370 Treat thread-specific signals differently from process-general signals.
1371 Block all signals while handling fatal error; that's safer.
1372 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
1374 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
1375 Ignore SIGPIPE unless batch.
1376 (emacs_backtrace): Output backtrace for the appropriate thread,
1377 which is not necessarily the main thread.
1378 * syssignal.h: Include <stdbool.h>.
1379 (emacs_raise): New macro.
1380 * xterm.c (x_connection_signal): Remove; no longer needed
1381 now that we use sigaction.
1382 (x_connection_closed): No need to mess with sigmask now.
1383 (x_initialize): No need to reset SIGPIPE handler here, since
1384 init_signals does this for us now.
1386 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
1388 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
1389 background rect may be larger (Bug#12245).
1391 2012-09-23 Chong Yidong <cyd@gnu.org>
1393 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
1395 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
1397 * .gdbinit: Just stop at fatal_error_backtrace.
1398 See Stefan Monnier's request in
1399 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
1400 Remove no-longer-used query of system type.
1402 2012-09-22 Chong Yidong <cyd@gnu.org>
1404 * search.c (Freplace_match): Doc fix (Bug#12325).
1406 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
1408 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
1409 (Fline_end_position): Doc fix.
1411 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
1413 2012-09-22 Chong Yidong <cyd@gnu.org>
1415 * dispextern.h (struct image_type): Add new slot, storing a type
1416 initialization function.
1418 * image.c (define_image_type): Call the image initializer function
1419 if it is defined. Arguments and return value changed.
1420 (valid_image_p, make_image): Callers changed.
1421 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
1422 (gif_type, imagemagick_type, svg_type, gs_type):
1423 Add initialization functions.
1424 (Finit_image_library): Call lookup_image_type.
1425 (CHECK_LIB_AVAILABLE): Macro deleted.
1426 (lookup_image_type): Call define_image_type here, rather than via
1427 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
1428 (syms_of_image): Move define_image_type calls for xbm_type and
1429 pbm_type to lookup_image_type.
1431 2012-09-22 Eli Zaretskii <eliz@gnu.org>
1433 * keyboard.c (timer_check_2): Move calculation of 'timers' and
1434 'idle_timers' from here ...
1435 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
1436 lists, to avoid infloops when the timer does something stupid,
1437 like reinvoke itself with the same or smaller time-out.
1440 2012-09-22 Martin Rudalics <rudalics@gmx.at>
1442 * window.c (Fsplit_window_internal): Handle only Qt value of
1443 Vwindow_combination_limit separately.
1444 (Qtemp_buffer_resize): New symbol.
1445 (Vwindow_combination_limit): New default value.
1448 2012-09-22 Eli Zaretskii <eliz@gnu.org>
1450 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
1451 the new overlay string. (Bug#10159)
1453 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
1455 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
1456 or that fprintf is async-signal-safe. POSIX doesn't require
1459 2012-09-22 Chong Yidong <cyd@gnu.org>
1461 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
1464 2012-09-22 Kenichi Handa <handa@gnu.org>
1466 * composite.c (composition_reseat_it): Handle the case that a
1467 grapheme cluster is not covered by a single font (Bug#12352).
1469 2012-09-21 Chong Yidong <cyd@gnu.org>
1471 * image.c (define_image_type): Avoid adding duplicate types to
1472 image_types (Bug#12463). Suggested by Jörg Walter.
1474 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1476 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
1477 (print_load_command_name): Add case LC_DATA_IN_CODE.
1478 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
1480 2012-09-21 Glenn Morris <rgm@gnu.org>
1482 * eval.c (Frun_hook_with_args_until_success)
1483 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
1485 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
1487 * fileio.c (Ffile_selinux_context): Only call freecon when
1488 lgetfilecon succeeded.
1489 (Fset_file_selinux_context): Likewise. (Bug#12444)
1491 2012-09-21 Eli Zaretskii <eliz@gnu.org>
1493 * xdisp.c (try_window_reusing_current_matrix): Under bidi
1494 reordering, locate the cursor by calling set_cursor_from_row; if
1495 that fails, clear the desired glyph matrix before returning a
1496 failure indication to the caller. Fixes leaving garbled display
1497 when fast scrolling with a down-key. (Bug#12403)
1498 (compute_stop_pos_backwards): Fix a typo that caused crashes while
1499 scrolling through multibyte text.
1501 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
1503 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
1504 calling mark_vectorlike since that's the one that marks the window.
1505 (mark_discard_killed_buffers): Mark the final cdr.
1506 * window.h (struct window): Move prev/next_buffers to the
1507 non-standard fields.
1508 * window.c (make_window): Initialize prev/next_buffers manually.
1510 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
1512 Omit unused arg EXPECTED from socket hooks.
1513 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
1514 * nsterm.m (ns_term_init):
1515 * termhooks.h (struct terminal.read_socket_hook):
1516 * w32inevt.c (w32_console_read_socket):
1517 * w32term.c (w32_read_socket):
1518 * xterm.c (XTread_socket):
1519 Omit unused arg EXPECTED. All callers changed.
1520 (store_user_signal_events): Return void, not int, since callers no
1521 longer care about the return value. All uses changed.
1523 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
1525 * w32gui.h (XParseGeometry): Do not declare.
1527 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
1529 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
1530 Ignore 'expected'. See Eli Zaretskii in
1531 <http://bugs.gnu.org/12471#8> (last line).
1533 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
1534 (XParseGeometry): Now static. Substitute extremal values for
1535 values that are out of range.
1537 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
1539 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
1541 * nsfns.m (XParseGeometry): Remove.
1542 (Fx_create_frame): Call x_set_offset to correctly interpret
1543 top_pos in geometry.
1545 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
1546 (Fx_parse_geometry): If there is a space in string, call
1547 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
1549 2012-09-17 Eli Zaretskii <eliz@gnu.org>
1551 * search.c (scan_buffer): Use character positions in calls to
1552 region_cache_forward and region_cache_backward, not byte
1553 positions. (Bug#12196)
1555 * w32term.c (w32_read_socket): Set pending_signals to 1, like
1556 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
1558 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
1559 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
1560 emacs_blocked_malloc, now deleted.
1562 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
1564 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
1565 The workaround was for improving performance on Solaris 2.4, but
1566 is getting in the way now. Emacs will still work if someone is
1567 still running Solaris 2.4 in a museum somewhere; Sun dropped
1568 support for Solaris 2.4 in 2003.
1569 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
1570 * process.c (create_process) [HAVE_WORKING_VFORK]:
1571 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
1572 since Emacs no longer uses vfork on that platform.
1574 2012-09-17 Glenn Morris <rgm@gnu.org>
1576 * emacs.c: Use COPYRIGHT.
1578 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
1580 Remove configure's --without-sync-input option (Bug#12450).
1581 When auditing signal-handling in preparation for cleaning it up,
1582 I found that SYNC_INPUT has race conditions and would be a real
1583 pain to fix. Since it's an undocumented and deprecated
1584 configure-time option, now seems like a good time to remove it.
1585 Also see <http://bugs.gnu.org/11080#16>.
1586 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
1587 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
1588 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
1589 (malloc_hysteresis):
1590 (check_depth) [XMALLOC_OVERRUN_CHECK]:
1591 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
1592 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
1593 (dont_register_blocks, bytes_used_when_reconsidered)
1594 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
1595 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
1596 [!SYSTEM_MALLOC && !SYNC_INPUT]:
1597 Remove. All uses removed.
1598 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
1599 implementation, one that depends on whether the new macro
1600 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
1602 * atimer.c (run_timers, handle_alarm_signal):
1603 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
1604 (handle_async_input, process_pending_signals)
1605 (handle_input_available_signal, init_keyboard):
1606 * nsterm.m (ns_read_socket):
1607 * process.c (wait_reading_process_output):
1608 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
1609 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
1611 * xterm.c (XTread_socket):
1613 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
1614 * eval.c (handling_signal): Remove. All uses removed.
1615 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
1616 All uses replaced with the SYNC_INPUT version.
1617 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
1619 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
1622 * font.c (Ffont_shape_gstring): Remove unused local.
1624 2012-09-16 Glenn Morris <rgm@gnu.org>
1626 * Makefile.in (clean): No longer run nextstep's clean.
1628 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
1630 (ns-app): Move here from ns.mk, and simplify.
1631 (clean): Simplify nextstep entry.
1632 * ns.mk: Remove file.
1634 2012-09-17 Kenichi Handa <handa@gnu.org>
1636 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
1637 not covert the last few charactes.
1639 2012-09-16 Kenichi Handa <handa@gnu.org>
1641 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
1642 here, but just check the validity of glyphs in the glyph-string.
1644 2012-09-16 Martin Rudalics <rudalics@gmx.at>
1646 * window.c (Fwindow_parameter, Fset_window_parameter):
1647 Accept any window as argument (Bug#12452).
1649 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
1651 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
1652 to ns_term_init to avoid memory leak.
1654 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
1655 explicit retain/release.
1656 (ns_term_init): Only allow one display. Initialize outerpool and
1659 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
1661 Port _setjmp fix to POSIXish hosts as well as Microsoft.
1662 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
1663 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
1664 the Microsoft problem in a different way, by altering ../nt/config.nt.
1666 2012-09-15 Eli Zaretskii <eliz@gnu.org>
1681 * w16select.c: Remove inclusion of setjmp.h, as it is now included
1682 by lisp.h. This completes removal of setjmp.h inclusion
1683 erroneously announced in the previous commit. (Bug#12446)
1685 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
1688 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
1689 not defined as a macro. The latter happens on MS-Windows.
1692 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
1694 Port better to POSIX hosts lacking _setjmp (Bug#12446).
1695 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
1696 Some instances of '#include <setjmp.h>' removed, if the
1697 only reason for the instance was because "lisp.h" was included.
1698 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
1699 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
1700 and _longjmp with the new symbols. Emacs already uses _setjmp if
1701 available, so this change affects only POSIXish hosts that have
1702 sigsetjmp but not _setjmp, such as some versions of Solaris and
1703 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
1704 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
1705 (png_load_body) [HAVE_PNG]:
1706 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
1707 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
1708 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
1709 since PNG requires jmp_buf. This is the only exception to the
1710 general rule that we now use sys_setjmp and sys_longjmp.
1711 This exception is OK since this code does not change the signal
1712 mask or longjmp out of a signal handler.
1714 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
1716 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
1717 Include "syssignal.h", for 'main_thread'.
1719 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
1721 Avoid out-of-range marker position (Bug#12426).
1722 * insdel.c (replace_range, replace_range_2):
1723 Adjust markers before overlays, as suggested by comments.
1724 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
1725 Remove redundant check before calling offset_intervals.
1727 2012-09-14 Martin Rudalics <rudalics@gmx.at>
1729 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
1730 current buffer (Bug#12387).
1732 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
1734 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
1736 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
1738 Use a more backwards-compatible timer format (Bug#12430).
1739 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
1740 vector element, not from the 4th, since PSECS is now at the end.
1741 (Fcurrent_idle_time): Doc fix.
1743 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
1745 Function to mark objects and remove killed buffers at once.
1746 * alloc.c (discard_killed_buffers): Rename to ...
1747 (mark_discard_killed buffers) ... new name. Add marking
1748 of remaining objects. Fix comment. Adjust users.
1749 (mark_object): Do not touch frame buffer lists here.
1750 * frame.c (delete_frame): Reset frame buffer lists here.
1752 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
1754 Better workaround for GNOME bug when --enable-gcc-warnings.
1755 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
1756 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
1757 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
1759 Simplify SIGIO usage (Bug#12408).
1760 The code that dealt with SIGIO was crufty and confusing, e.g., it
1761 played tricks like "#undef SIGIO" but these tricks were not used
1762 consistently. Simplify mostly by not #undeffing standard symbols,
1763 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
1764 or not as we please) rather than "defined SIGIO" (standard symbol
1765 that we probably shouldn't #undef).
1766 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
1767 Modules that need it can include it.
1768 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
1769 * dispextern.h (ignore_sigio): New decl.
1770 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
1771 unconditionally, since it's now a no-op if !USABLE_SIGIO.
1772 * emacs.c (shut_down_emacs):
1773 * keyboard.c (kbd_buffer_store_event_hold):
1774 Use ignore_sigio rather than invoking 'signal' directly.
1775 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
1777 (FIONREAD, SIGIO): Do not #undef.
1778 (tty_read_avail_input): Use #error rather than a syntax error.
1779 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
1780 for I_PIPE, used by SETUP_SLAVE_PTY.
1781 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
1782 * sysdep.c (croak): Remove; no longer needed. This bit of
1783 temporary code, with Fred N. Fish's comment that it's temporary,
1784 has been in Emacs since at least 1992!
1785 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
1786 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
1787 * syssignal.h (croak): Remove decl.
1788 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
1789 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
1790 now that we're termios-only.
1791 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
1792 * term.c (dissociate_if_controlling_tty): Use #error rather than
1795 Work around GCC and GNOME bugs when --enable-gcc-warnings.
1796 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
1797 to work around GNOME bug 683906.
1798 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
1799 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
1800 This works around GCC bug 54561.
1802 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
1804 More fixes for 'volatile' and setjmp/longjmp.
1805 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
1806 * image.c (struct png_load_context) [HAVE_PNG]: New type.
1807 (png_load_body) [HAVE_PNG]:
1808 (jpeg_load_body) [HAVE_JPEG]:
1809 New function, with most of the old parent function's body.
1810 (png_load) [HAVE_PNG]:
1811 (jpeg_load) [HAVE_JPEG]:
1812 Invoke the new function, to avoid longjmp munging our locals.
1813 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
1814 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
1815 longjmp is passed 2, as the C standard doesn't guarantee this.
1816 Instead, store the failure code into mgr->failure_code.
1818 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
1820 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
1821 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
1822 (syms_of_keyboard): Remove support for unread-command-char.
1824 2012-09-12 Eli Zaretskii <eliz@gnu.org>
1826 * w32proc.c (sys_kill): If PID is our process ID and the signal is
1827 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
1828 violation. (Bug#12426)
1830 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
1832 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
1834 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
1836 * eval.c: Add `inhibit-debugger'.
1837 (Qinhibit_debugger): New symbol.
1838 (call_debugger): Bind it instead of Qdebug_on_error.
1839 (maybe_call_debugger): Test Vinhibit_debugger.
1840 (syms_of_eval): Define inhibit-debugger.
1841 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
1842 (syms_of_xdisp): Remove inhibit-debug-on-message.
1844 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
1846 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
1847 If a nonvolatile local variable is written before a _longjmp to
1848 the frame containing the variable, and is read after the _longjmp,
1849 the value read is indeterminate. Some local variables of type
1850 'struct handler' and 'struct catchtag' are used in this way, so
1851 mark each of their slots as volatile if the slot can be set before
1852 _longjmp and read afterwards.
1853 * lisp.h (struct handler): var and chosen_clause are now volatile.
1854 (struct catchtag): val, next, and pdlcount are now volatile.
1856 * bidi.c (bidi_push_it, bidi_pop_it):
1857 * fns.c (copy_hash_table):
1858 * image.c (define_image_type):
1859 * keyboard.c (kbd_buffer_store_event_hold):
1860 * process.c (Fprocess_send_eof):
1861 * xfaces.c (x_create_gc) [HAVE_NS]:
1862 * xgselect.c (xg_select):
1863 Prefer assignment to memcpy when either will do.
1865 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
1866 Use pointer-to-a-pointer to simplify and avoid a NILP check each
1867 time an item is removed. No need to mark this function 'inline';
1868 the compiler knows better than we do.
1870 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
1872 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
1873 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
1874 to change_frame_size (Bug#12388).
1875 (windowDidResize:): Pass YES to updateFrameSize.
1877 * nsterm.h: Add delay parameter to updateFrameSize.
1879 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
1881 Discard killed buffers from deleted window and frame objects.
1882 This reduces an amount of references to killed buffers and
1883 helps GC to reclaim them faster.
1884 * alloc.c (discard_killed_buffers): New function.
1885 (mark_object): Use it for deleted windows and frames.
1886 (mark_object): If symbol's value is set up for a killed buffer
1887 or deleted frame, restore it's global binding.
1888 * data.c (swap_in_global_binding): Add GC notice.
1889 (swap_in_symval_forwarding): Use convenient set_blv_where.
1890 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
1891 * window.h: ... to here.
1893 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
1895 Convenient macro to check whether the buffer is live.
1896 * buffer.h (BUFFER_LIVE_P): New macro.
1897 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
1898 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
1900 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1902 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
1903 composition cases (Bug#12364).
1905 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
1906 overhang of succeeding glyphs overlapping box cursor.
1908 * w32term.c (x_draw_glyph_string): Likewise.
1910 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
1912 Simplify, document, and port floating-point (Bug#12381).
1913 The porting part of this patch fixes bugs on non-IEEE platforms
1914 with frexp, ldexp, logb.
1915 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
1917 * floatfns.c: Simplify discussion of functions that Emacs doesn't
1918 support, by removing commented-out code and briefly listing the
1919 C89 functions excluded. The commented-out stuff was confusing
1920 maintenance, e.g., we thought we needed cbrt but it was commented out.
1921 (logb): Remove decl; no longer needed.
1922 (isfinite): New macro, if not already supplied.
1923 (isnan): Don't replace any existing macro.
1924 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
1925 are present on all C89 platforms.
1926 (Ffrexp): Do not special-case zero, as frexp does the right thing
1928 (Flogb): Do not use logb, as it doesn't have the desired meaning
1929 on hosts that use non-base-2 floating point. Instead, stick with
1930 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
1931 frexp, to avoid getting an unspecified result.
1933 * xdisp.c (Qinhibit_debug_on_message): Now static.
1935 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
1937 * nsterm.m (ns_update_begin): Set clip path to whole view by using
1938 NSBezierPath (Bug#12131).
1940 2012-09-10 Chong Yidong <cyd@gnu.org>
1942 * fns.c (Fdelq, Fdelete): Doc fix.
1944 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
1946 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
1947 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
1949 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
1951 * lisp.h (make_lisp_ptr): New macro to replace XSET.
1952 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
1955 2012-09-09 Eli Zaretskii <eliz@gnu.org>
1957 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
1958 left fringe if the window has a left margin. This avoids leaving
1959 traces of the cursor because its leftmost pixel is not drawn over.
1961 * dispnew.c (update_window_line): When the left margin area of a
1962 screen line is updated, set the redraw_fringe_bitmaps_p flag of
1963 that screen line. (Bug#12277)
1965 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
1967 Assume C89 or later for math functions (Bug#12381).
1968 This simplifies the code, and makes it a bit smaller and faster,
1969 and (most important) makes it easier to clean up signal handling
1970 since we can stop worring about floating-point exceptions in
1971 library code. That was a problem before C89, but the problem
1972 went away many years ago on all practical Emacs targets.
1973 * data.c, image.c, lread.c, print.c:
1974 Don't include <math.h>; no longer needed.
1975 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
1976 might be autoconfigured, as that never happens.
1978 * doprnt.c (DBL_MAX_10_EXP):
1979 * print.c (DBL_DIG):
1980 Remove. C89 or later always defines these.
1981 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
1982 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
1983 (arith_error, domain_error, domain_error2):
1984 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
1985 no longer needed -- we simply return what C returns. All uses removed.
1986 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
1988 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
1989 Remove. All uses expanded, as these macros are no longer used
1990 more than once and are now more trouble than they're worth.
1991 (Ftan): Use tan, not sin / cos.
1992 (Flogb): Assume C89 frexp.
1993 (fmod_float): Assume C89 fmod.
1994 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
1995 (init_floatfns): Remove. All uses removed.
1997 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
1999 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
2000 compositeToPoint for OSX < 10.6 (Bug#12390).
2002 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
2004 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
2005 This produces more-accurate results.
2007 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
2009 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
2010 changes (Bug#12088).
2012 2012-09-08 Chong Yidong <cyd@gnu.org>
2014 * syntax.c (Fstring_to_syntax): Doc fix.
2016 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
2018 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
2019 in the internal border.
2020 (x_set_window_size): Remove static variables and their usage.
2021 (ns_redraw_scroll_bars): Fix NSTRACE arg.
2022 (ns_after_update_window_line, ns_draw_fringe_bitmap):
2023 Remove fringe/internal border adjustment (Bug#11052).
2024 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
2025 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
2026 (ns_fix_rect_ibw): Remove.
2027 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
2028 (ns_dumpglyphs_box_or_relief): Ditto.
2029 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
2031 (ns_dumpglyphs_image): Ditto.
2032 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
2034 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
2035 their usage. Add fringe_extended_p and its use as in other terms.
2036 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
2037 scroll bar was removed.
2038 (updateFrameSize): New function.
2039 (windowDidResize): Move code to updateFrameSize and call it.
2041 * nsterm.h (EmacsView): Add updateFrameSize.
2043 2012-09-07 Chong Yidong <cyd@gnu.org>
2045 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
2047 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
2049 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
2051 More signal-handler cleanup (Bug#12327).
2052 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
2053 Problem introduced when merging patches. Noted by Eli Zaretskii in
2054 <http://bugs.gnu.org/12327#67>.
2055 * floatfns.c: Comment fix.
2056 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
2057 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
2058 and anyway the declaration is harmless even if SIGDANGER is not defined.
2059 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
2060 defined BROKEN_FIONREAD). systty.h formerly did this, but other
2061 source files not surprisingly expected syssignal.h to define, or
2062 not define, SIGIO, and it's cleaner to do it that way, for consistency.
2063 Include <sys/ioctl.h>, for FIONREAD.
2064 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
2065 This eliminates a problem whereby other files mysteriously had
2066 to include "syssignal.h" before including "systty.h" if they
2067 wanted to use "#ifdef SIGIO".
2069 2012-09-07 Eli Zaretskii <eliz@gnu.org>
2071 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
2073 * w32.c (sigemptyset): Empty the set.
2074 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
2076 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
2078 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
2080 * alloc.c (mark_buffer): Revert unsafe marking optimization.
2081 (mark_object): Likewise for frame objects.
2083 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
2085 * syssignal.h (handle_on_main_thread): Always declare,
2086 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
2087 This ports to platforms without HAVE_PTHREAD.
2089 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
2091 Signal-handler cleanup (Bug#12327).
2092 Emacs's signal handlers were written in the old 4.2BSD style with
2093 sigblock and sigmask and so forth, and this led to some
2094 inefficiencies and confusion. Rewrite these to use
2095 pthread_sigmask etc. without copying signal sets around. Also,
2096 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
2097 'signal', and instead use functions that do not attempt to take
2098 over the system name space. This patch causes Emacs's text
2099 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
2100 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
2101 Do not include <signal.h> or "syssignal.h", as these
2102 modules do not use signals.
2103 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
2104 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
2105 Do not include <signal.h>, as "syssignal.h" does that for us now.
2106 * atimer.c (sigmask_atimers): New function.
2107 (block_atimers, unblock_atimers): New functions,
2108 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
2110 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
2111 no longer needed here.
2112 * emacs.c (main): Inspect existing signal handler with sigaction,
2113 so that there's no need to block and unblock SIGHUP.
2114 * sysdep.c (struct save_signal): New member 'action', replacing
2115 old member 'handler'.
2116 (save_signal_handlers, restore_signal_handlers):
2117 Use sigaction instead of 'signal' to save and restore.
2118 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
2119 New function. All users of 'signal' modified to use set_sighandler
2120 if they're writeonly, and to use sys_signal if they're read+write.
2121 (emacs_sigaction_init, forwarded_signal): New functions.
2122 (sys_signal): Remove. All uses replaced by calls to sigaction
2123 and emacs_sigaction_init, or by direct calls to 'signal'.
2124 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
2125 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
2126 all uses replaced by pthread_sigmask etc. calls.
2127 * syssignal.h: Include <signal.h>.
2128 (emacs_sigaction_init, forwarded_signal): New decls.
2129 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
2130 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
2131 (sigmask, sys_sigmask): Remove; no longer needed.
2132 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
2133 (sigblock, sigunblock, sigfree):
2134 (sigsetmask) [!defined sigsetmask]:
2135 Remove. All uses replaced by pthread_sigmask.
2136 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
2137 no longer need to be replaced, and its typical old uses
2138 are now done via emacs_sigaction_init and sigaction.
2139 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
2140 (sys_sigdel): Remove; unused.
2141 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
2143 2012-09-06 Eli Zaretskii <eliz@gnu.org>
2145 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
2146 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
2148 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
2150 Explicitly mark buffer_defaults and buffer_local_symbols.
2151 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
2152 mark_local_symbols here.
2153 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
2154 since special buffers aren't marked here any more.
2155 (allocate_buffer): Chain new buffer with all_buffers here...
2156 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
2158 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
2159 (syms_of_buffer): Remove staticpro of the above.
2160 (init_buffer_once): Set names for buffer_defaults and
2161 buffer_local_symbols.
2163 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
2165 Use bool for booleans in font-related modules.
2166 * font.c (font_intern_prop, font_style_to_value)
2167 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
2168 (generate_otf_features, font_check_otf_features, font_check_otf)
2169 (font_match_p, font_list_entities, font_at):
2170 * fontset.c (fontset_id_valid_p, reorder_font_vector
2171 (fontset_find_font, Fset_fontset_font)
2172 (face_suitable_for_char_p) [0]:
2173 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
2174 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
2175 (m17n_flt_initialized, ftfont_shape_by_flt):
2176 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
2177 * nsfont.m (nsfont_draw):
2178 * w32font.c (w32font_draw):
2179 * w32term.c (x_draw_glyphless_glyph_string_foreground):
2180 Use bool for booleans.
2181 * font.h: Adjust to above API changes.
2182 (struct font, struct font_driver, struct font_driver_list):
2183 Use bool for booleans.
2184 (struct font): Remove useless member encoding_type.
2186 * fontset.c, xftfont.c: Omit unnecessary static decls.
2188 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
2190 * alloc.c (mark_object): Revert window marking code
2191 since it's unsafe for the Fset_window_configuration.
2193 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
2195 Fix race conditions with signal handlers and errno (Bug#12327).
2196 Be more systematic about preserving errno whenever a signal
2197 handler returns, even if it's not in the main thread. Do this by
2198 renaming signal handlers to distinguish between signal delivery
2199 and signal handling. All uses changed.
2200 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
2201 * data.c (deliver_arith_signal): Rename from arith_error.
2202 * dispnew.c (deliver_window_change_signal): Rename from
2203 window_change_signal.
2204 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
2205 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
2206 * keyboard.c (deliver_input_available_signal): Rename from
2207 input_available_signal.
2208 (deliver_user_signal): Rename from handle_user_signal.
2209 (deliver_interrupt_signal): Rename from interrupt_signal.
2210 * process.c (deliver_pipe_signal): Rename from send_process_trap.
2211 (deliver_child_signal): Rename from sigchld_handler.
2212 * atimer.c (handle_alarm_signal):
2213 * data.c (handle_arith_signal):
2214 * dispnew.c (handle_window_change_signal):
2215 * emacs.c (handle_fatal_signal, handle_danger_signal):
2216 * keyboard.c (handle_input_available_signal):
2217 * keyboard.c (handle_user_signal, handle_interrupt_signal):
2218 * process.c (handle_pipe_signal, handle_child_signal):
2219 New functions, with the actual signal-handling code taken from the
2220 original respective signal handlers, sans the sporadic attempts to
2221 preserve errno, since that's now done by handle_on_main_thread.
2222 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
2223 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
2224 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
2226 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
2227 Move initialization of main_thread to sysdep.c's init_signals.
2228 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
2229 our usage, and simplifies the mainline code.
2230 (record_child_status_change): New static function, as a helper
2231 for handle_child_signal, and with most of the old child handler's
2233 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
2234 (handle_child_signal): Use the above.
2235 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
2236 Moved here from emacs.c.
2237 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
2238 code moved here from emacs.c's main function.
2239 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
2240 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
2241 This lets callers save and restore errno properly.
2243 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
2245 Remove redundant or unused things here and there.
2246 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
2247 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
2248 * editfns.c (Fcompare_buffer_substrings): Likewise.
2249 * frame.h (struct terminal, struct font_driver_list):
2250 Remove redundant declarations.
2251 * window.h (Qleft, Qright): Likewise.
2253 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
2255 Do not mark objects from deleted buffers, windows and frames.
2256 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
2257 (mark_object): Likewise for windows and frames.
2259 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
2261 * alloc.c (valid_lisp_object_p): Treat killed buffers,
2262 buffer_defaults and buffer_local_symbols as valid objects.
2263 Return special value to denote them.
2265 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
2267 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
2268 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
2269 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
2270 (file_name_absolute_p, Fsubstitute_in_file_name):
2271 (check_executable, check_writable, Ffile_accessible_directory_p)
2272 (Fset_file_selinux_context, Fdefault_file_modes)
2273 (Finsert_file_contents, choose_write_coding_system)
2274 (Fwrite_region, build_annotations, a_write, e_write)
2276 * filelock.c (boot_time_initialized, get_boot_time)
2277 (get_boot_time_1, lock_file_1, within_one_second):
2278 * floatfns.c (in_float):
2279 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
2280 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
2281 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
2282 * lisp.h (struct Lisp_Hash_Table.cmpfn):
2283 * window.c (compare_window_configurations):
2284 Use bool for booleans.
2285 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
2286 (Fdefault_file_modes): Now mode_t, not int, for modes.
2287 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
2288 (internal_delete_file): Now returns void, not a (boolean) int,
2289 since nobody was looking at the return value.
2290 * lisp.h, window.h: Adjust to above API changes.
2292 * xdisp.c (set_message): Simplify and reindent last change.
2294 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
2296 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
2298 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
2300 * eval.c (call_debugger): Make the function non-static so that we
2301 can call it from set_message.
2303 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
2304 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
2306 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
2308 Give more-useful info on a fatal error (Bug#12328).
2309 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
2310 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
2311 of doing the work ourselves.
2312 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
2313 do most of the work.
2314 (fatal_error_backtrace): New function, taken from the guts
2315 of the old fatal_error_signal, but with a new option to output
2317 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
2318 info about the signal than just its number.
2319 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
2320 * sysdep.c: Include <execinfo.h>
2321 (emacs_backtrace): New function, taken partly from the previous
2322 code of the 'die' function.
2323 (emacs_abort): Call fatal_error_backtrace rather than abort.
2325 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
2327 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
2328 eager (load-time) macro-expansion.
2329 * lisp.mk (lisp): Add macroexp.
2331 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
2333 Simplify redefinition of 'abort' (Bug#12316).
2334 Do not try to redefine the 'abort' function. Instead, redo
2335 the code so that it calls 'emacs_abort' rather than 'abort'.
2336 This removes the need for the NO_ABORT configure-time macro
2337 and makes it easier to change the abort code to do a backtrace.
2338 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
2339 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
2340 Remove; sysdep.c's emacs_abort now takes its place.
2341 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
2342 'abort' changed to use 'emacs_abort'.
2343 * msdos.c (dos_abort) [defined abort]: Remove; not used.
2344 (abort) [!defined abort]: Rename to ...
2345 (emacs_abort): ... new name.
2346 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
2347 the place of the old 'abort' in emacs.c.
2348 * w32.c, w32fns.c (abort): Do not #undef.
2349 * w32.c (emacs_abort): Rename from w32_abort.
2351 2012-09-04 Eli Zaretskii <eliz@gnu.org>
2353 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
2354 offsets[j].dv, since the y axis of the screen coordinates points
2355 down, while the y axis of the font definition coordinates points
2356 up. This fixes display of Arabic diacritics such as KASRA and
2357 KASRATAN. (Bug#11860)
2359 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
2361 Be more systematic about _setjmp vs setjmp.
2362 * alloc.c (test_setjmp, mark_stack):
2363 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
2364 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
2365 (png_load, my_error_exit, jpeg_load):
2366 * process.c (send_process_trap, send_process):
2367 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
2368 The underscored versions are up to 30x faster on some hosts.
2369 Formerly, the code used setjmp+longjmp sometimes and
2370 _setjmp+_longjmp at other times, with no particular reason to
2371 prefer setjmp+longjmp.
2373 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
2375 Fix minor problem found by static checking.
2376 * buffer.c (Fdelete_all_overlays): Return nil.
2378 2012-09-03 Martin Rudalics <rudalics@gmx.at>
2380 * buffer.c (Fdelete_all_overlays): New function.
2382 2012-09-03 Chong Yidong <cyd@gnu.org>
2384 * gtkutil.c: Add extern decl for Qxft.
2386 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>

2400 All callers changed.
2401 * eval.c (interactive_p): Omit always-true boolean argument
2402 EXCLUDE_SUBRS_P. All callers changed.
2403 * dispextern.h, lisp.h: Reflect above API changes.
2404 * firstfile.c (dummy): Use the address of 'main', whose signature
2405 won't change, instead of the address of 'initialize', whose
2406 signature just changed from int to bool.
2407 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
2408 * msdos.c (fatal_error_in_progress): ... from here.
2409 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
2411 (redisplay_internal, unwind_redisplay): Simply clear
2412 REDISPLAYING_P when unwinding, instead of saving its previous,
2413 always-false value and then restoring it.
2415 Clean up some extern decls.
2416 Mostly, this hoists extern decls out of .c files and into .h files.
2417 That way, we're more likely to catch errors if the interfaces change.
2418 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
2419 declare xg_mark_data.
2420 * dispextern.h (x_frame_parm_handlers):
2422 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
2423 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)

2438 * xfont.c (x_clear_errors):
2439 * xterm.c (x_frame_parm_handlers):
2440 Remove now-redundant extern decls.
2441 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
2442 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
2444 * xfaces.c: Remove unnecessary static decls.
2445 * xterm.c (updating_frame): Remove decl of nonexistent object.
2447 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
2448 when building globals.h, as the objects that are not built on
2449 this host are not needed to compile C files on this host.
2451 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
2453 * gtkutil.h: Remove prototype for x_wm_set_size_hint.

2480 (set_intervals_multibyte_1, set_intervals_multibyte):
2481 * keyboard.c (decode_timer):
2482 Use bool for boolean.
2483 * intervals.h, lisp.h, systime.h: Reflect above API changes.
2484 * editfns.c (struct info): Use 1-bit unsigned bitfields for booleans.
2486 2012-09-02 Chong Yidong <cyd@gnu.org>
2488 * keymap.c (push_key_description): Print M-TAB as C-M-i
2491 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
2493 * makefile.w32-in (CCL_H, W32FONT_H): New macros.

2501 2012-09-01 Eli Zaretskii <eliz@gnu.org>
2503 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
2504 more than one grapheme cluster passed to the shaper: compute the
2505 offset adjustment values separately for each cluster. (Bug#11860)
2507 * image.c: Restore mistakenly removed inclusion of w32.h. Without
2508 it, GCC doesn't see prototypes of w32_delayed_load, and complains
2509 about implicit conversions from integer to pointer.
2511 2012-09-01 Daniel Colascione <dancol@dancol.org>
2513 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
2514 system used too early.
2516 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
2518 Better seed support for (random).

2547 * process.c: Include TERM_HEADER instead of listing all possible
2548 window-system headers.

2551 Define FRAME_X_SCREEN, FRAME_X_VISUAL.
2553 * menu.c: Include TERM_HEADER instead of listing all possible
2554 window-system headers.
2556 * keyboard.h: Declare ignore_mouse_drag_p whenever we have a
2559 * keyboard.c: Include TERM_HEADER instead of listing all possible
2560 window-system headers.
2562 * image.c: Include TERM_HEADER instead of listing all possible
2563 window-system headers. Declare Vlibrary_cache when compiling for
2566 * gtkutil.h (xg_list_node_): Include xterm.h to pick up needed
2567 window system declarations.
2569 * frame.h: Move common functions here: set_frame_menubar,
2570 x_set_window_size, x_sync, x_get_focus_frame,
2571 x_set_mouse_position, x_set_mouse_pixel_position,
2572 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

2596 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
2598 Remove mark_ttys function and fix tty_display_info initialization.
2599 * lisp.h (mark_ttys): Remove prototype.
2600 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
2601 to mark_ttys because all possible values of 'top_frame' slot are
2602 the frames which are reachable from Vframe_list.
2603 * term.c (mark_ttys): Remove.
2604 (init_tty): Safely initialize 'top_frame' slot with Qnil.
2606 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>

2611 'auto_raise', 'auto_lower', 'no_split', 'explicit_name',
2612 'window_sizes_changed', 'mouse_moved' and 'pointer_invisible'
2613 bitfields from unsigned char to unsigned.

2628 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
2629 for GCC 4.7.1 x86-64.
2631 2012-08-30 Glenn Morris <rgm@gnu.org>
2633 * lread.c (init_lread): For out-of-tree builds, only add the
2634 source directory's site-lisp dir to the load-path if it exists,
2635 consistent with in-tree builds. (Bug#12302)
2637 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>
2639 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize

2648 (addString:row:): Remove return self, declare return value as void.
2649 (addSplit): Remove return self, declare return value as void.
2650 (clicked:): Remove return self, declare return value as void.
2651 Set dialog_return to button_values[seltag]. Code formatting change.
2652 (initFromContents:isQuestion:): Adjust call to process_dialog.
2653 Code formatting change.
2654 (timeout_handler:): Set timer_fired to YES.
2655 (runDialogAt:): Set timer_fired to NO.
2656 Handle click on close button as quit.
2658 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
2659 Add window_closed and button_values. Add void as return value for
2660 add(Button|String|Split). addButton takes int instead of Lisp_Object.
2661 Add process_dialog as new member.
2663 2012-08-28 Eli Zaretskii <eliz@gnu.org>
2665 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it
2666 is not one of the heaps we manage. (Bug#12242)

2725 (do_pending_window_change, change_frame_size)
2726 (change_frame_size_1, sit_for):
2727 Use bool for boolean.
2728 (clear_glyph_matrix_rows): Rename from enable_glyph_matrix_rows,
2729 and remove last int (actually boolean) argument, which was always 0.
2730 All callers changed.
2731 * dispextern.h, frame.h, lisp.h: Reflect above API changes.
2732 * dispextern.h (struct composition_it): Use bool for boolean.
2733 (struct glyph_matrix): Don't assume buffer sizes can fit in 'int'.
2734 (struct bidi_it): Use unsigned:1, not int, for boolean prev_was_pdf.
2735 * dired.c (file_name_completion):
2736 Use bool for boolean. (This was missed in an earlier change.)
2738 2012-08-27 Martin Rudalics <rudalics@gmx.at>
2740 * window.c (Fset_window_configuration): Revert first part of
2743 2012-08-27 Jan Djärv <jan.h.d@swipnet.se>
2745 * nsterm.h (NSPanel): New class variable dialog_return.
2747 * nsmenu.m (initWithContentRect:styleMask:backing:defer:):
2748 Initialize dialog_return.
2749 (windowShouldClose:): Use stop instead of stopModalWithCode.
2750 (clicked:): Ditto, and also set dialog_return (Bug#12258).
2751 (timeout_handler:): Use stop instead of abortModal. Send a dummy
2753 (runDialogAt:): Make ret Lisp_Object. Set it from dialog_return when
2756 2012-08-27 Paul Eggert <eggert@cs.ucla.edu>
2758 * composite.c, data.c, dbusbind.c, dired.c: Use bool for booleans.
2759 * composite.c (find_composition, composition_gstring_p)

2766 * dbusbind.c (xd_in_read_queued_messages):
2767 * dired.c (directory_files_internal, file_name_completion):
2768 Use bool for booleans.
2769 * dired.c (file_name_completion):
2770 * process.h (fd_callback):
2771 Omit int (actually boolean) argument. It wasn't being used.
2773 * composite.h, lisp.h: Reflect above API changes.
2775 * cmds.c, coding.c: Use bool for booleans.
2776 * cmds.c (move_point, Fself_insert_command):

2796 (Fset_coding_system_priority):
2797 * fileio.c (Finsert_file_contents):
2798 Use bool for booleans.
2799 * coding.h, lisp.h: Reflect above API changes.
2800 * coding.c: Remove unnecessary static function decls.
2801 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
2802 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
2803 not a boolean 'int', since callers never look at the return value.
2804 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
2805 * coding.h (decoding_buffer_size, encoding_buffer_size)
2806 (emacs_mule_string_char): Remove unused extern decls.
2807 (struct iso_2022_spec, struct coding_system):
2808 Use 'unsigned int : 1' for boolean fields, since there's more than one.
2809 (struct emacs_mule_spec): Remove unused field 'full_support'.
2810 All initializations removed.
2811 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
2813 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
2815 Fix spare memory change (Bug#12286).
2816 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
2817 (valid_lisp_object_p): Likewise.
2819 2012-08-27 Martin Rudalics <rudalics@gmx.at>
2821 * window.c (Fset_window_configuration): Record any window's old
2822 buffer if it's replaced (see Bug#8789). If the new current
2823 buffer doesn't appear in the selected window, go to its old
2826 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
2828 Special MEM_TYPE_SPARE to denote reserved memory.
2829 * alloc.c (enum mem_type): New memory type.
2830 (refill_memory_reserve): Use new type for spare memory.
2831 This prevents live_cons_p and live_string_p from incorrect
2832 detection of uninitialized objects from spare memory as live.
2834 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
2837 * Makefile.in (.PHONY): versioclean -> versionclean.
2839 Remove unused external symbols.
2840 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
2841 * window.c (Qwindow_valid_p, decode_valid_window):
2842 Now static, not extern.
2843 * data.c (Qinterval): Remove; unused.
2844 (syms_of_data): Do not define 'interval'.
2845 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
2846 * window.h (decode_valid_window):
2849 * character.c, charset.c, chartab.c: Use bool for booleans.
2850 * character.c (lisp_string_width, string_count_byte8)
2851 (string_escape_byte8):
2852 * charset.c (charset_map_loaded, load_charset_map, read_hex):
2853 (load_charset_map_from_file, map_charset_chars)
2854 (Fdefine_charset_internal, define_charset_internal)
2855 (Fdeclare_equiv_charset, find_charsets_in_text)
2856 (Ffind_charset_region, char_charset, Fiso_charset):

2858 (sub_char_table_set, sub_char_table_set_range)
2859 (char_table_set_range, optimize_sub_char_table)
2860 (map_sub_char_table):
2861 Use bool for boolean.
2862 * character.c (str_to_unibyte): Omit last boolean argument; it was
2863 always 0. All callers changed.
2864 * character.h, charset.h: Adjust to match previous changes.
2865 * character.h (char_printable_p): Remove decl of nonexistent function.
2866 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
2867 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
2868 are all boolean, so make them single-bit bitfields.
2870 * lisp.h (ASET): Remove attempt to detect side effects.
2871 It was meant to be temporary and it often doesn't work,
2872 because when IDX has side effects the behavior of IDX==IDX
2873 is undefined. See Stefan Monnier in
2874 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
2876 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
2878 * lisp.h (functionp): New function (extracted from Ffunctionp).
2879 (FUNCTIONP): Use it.
2880 * eval.c (Ffunctionp): Use it.
2882 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
2884 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
2885 as that's faster and simpler than static storage. Don't bother
2886 with the g_main_context_query overhead if g_main_context_pending
2887 says no events are pending.
2888 (gfds, gfds_size): Remove these static vars.
2889 (xgselect_initialize): Remove; no longer needed.
2890 All uses and decls removed.
2892 * emacs.c (fatal_error_signal_hook): Remove.
2893 All uses removed. This leftover from old code was always 0.
2895 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
2896 * casefiddle.c (casify_object, casify_region):
2897 * casetab.c (set_case_table):
2898 * category.c, category.h (word_boundary_p):
2899 * category.h (CHAR_HAS_CATEGORY):
2900 Use bool for booleans, instead of int.
2902 2012-08-25 Eli Zaretskii <eliz@gnu.org>
2904 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
2906 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
2908 On assertion failure, print backtrace if available.
2909 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
2910 (die) [ENABLE_CHECKING]: Print a backtrace if available.
2911 * Makefile.in (LIB_EXECINFO): New macro.
2914 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
2915 * bytecode.c (exec_byte_code):
2916 * callint.c (check_mark, Fcall_interactively):
2917 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
2918 (getenv_internal, sync_process_alive, call_process_exited):
2919 * lisp.h (USE_SAFE_ALLOCA):
2920 Use bool for booleans, instead of int.
2921 * lisp.h, process.h: Adjust prototypes to match above changes.
2922 * callint.c (Fcall_interactively): Don't assume the mark's
2923 offset fits in 'int'.
2925 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
2927 * buffer.c, buffer.h: Use bool for boolean.
2928 * buffer.c (reset_buffer_local_variables)
2929 (buffer_lisp_local_variables, Fset_buffer_modified_p)
2930 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
2931 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
2932 (overlay_touches_p, overlay_strings, Foverlay_put)
2933 (report_overlay_modification, call_overlay_mod_hooks):
2934 (mmap_enlarge, mmap_set_vars):
2935 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
2936 Use bool for booleans, instead of int.
2937 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
2938 since the 1-or-0 return value is always ignored anyway.
2939 (mmap_initialized_p):
2940 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
2941 * buffer.h, lisp.h: Adjust prototypes to match above changes.
2943 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
2945 * bidi.c: Use bool for boolean.
2946 This is a bit more readable, and makes the text segment of bidi.o
2947 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
2948 Presumably it's faster too.
2949 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
2951 (bidi_cache_find_level_change, bidi_cache_iterator_state)
2952 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
2953 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
2954 (bidi_explicit_dir_char, bidi_level_of_next_char)
2955 (bidi_find_other_level_edge, bidi_move_to_visually_next):
2956 Use bool for booleans, instead of int.
2957 * dispextern.h (bidi_init_it, bidi_paragraph_init)
2958 (bidi_unshelve_cache): Adjust decls to match code.
2960 2012-08-23 Martin Rudalics <rudalics@gmx.at>
2962 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
2965 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
2967 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
2968 * atimer.h: Include <stdbool.h>.
2970 2012-08-22 Dan Nicolaescu <dann@gnu.org>
2972 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
2973 compile time tests instead of run time tests on systems that do
2975 (FRAME_MAC_P): Remove leftover from deleted code.
2976 * frame.c (syms_of_frame): Remove leftover from deleted code.
2978 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
2980 * nsterm.m (insertText:): Don't clear modifiers if code is space.
2982 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
2984 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
2985 Otherwise, the compiler complains about (A?B:C) where B is void
2986 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
2987 (fontset_add): Return void, for FONTSET_ADD.
2989 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
2991 * alloc.c: Use bool for booleans.
2992 (gc_in_progress, abort_on_gc)
2993 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
2994 (dont_register_blocks) [GC_MALLOC_CHECK]:
2995 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
2996 (check_string_bytes, make_specified_string, memory_full)
2997 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
2998 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
2999 (mark_stack, valid_pointer_p, make_pure_string)
3000 (Fgarbage_collect, survives_gc_p, gc_sweep):
3001 Use bool for booleans, instead of int.
3002 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
3003 Remove unused local.
3004 * alloc.c (PURE_POINTER_P):
3005 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
3006 * editfns.c (Fformat):
3007 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
3009 * fns.c (sweep_weak_table):
3010 * lisp.h (suppress_checking, push_message, survives_gc_p)
3011 (make_pure_string, gc_in_progress, abort_on_gc):
3012 * lread.c (readchar, read1):
3013 * print.c (Fprin1_to_string):
3014 * xdisp.c (push_message):
3015 Use bool for booleans affected directly or indirectly by
3018 Make recently-introduced setters macros.
3019 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
3020 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
3021 (set_fontset_default, set_fontset_fallback): Rename from their
3022 upper-case counterparts, and make them functions rather than macros.
3023 This is more consistent with the other recently-introduced setters.
3024 These don't need to be inline, since they're local.
3026 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
3028 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
3029 the loop (Bug#12247).
3031 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
3033 * lisp.h (vcopy): Use memcpy rather than our own loop.
3034 This fixes a performance regression introduced by the recent
3035 addition of vcopy. This means 'vcopy' will need to be modified
3036 for a copying collector, but that's OK. Also, tighten the
3037 checking in the assertion.
3039 2012-08-21 Eli Zaretskii <eliz@gnu.org>
3041 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
3042 components for RTL text (Bug#11860). Adjust X-OFFSET of each
3043 non-base glyph for the width of the base character, according to
3044 what x_draw_composite_glyph_string_foreground expects.
3045 Generate WADJUST value according to composition_gstring_width's
3046 expectations, to produce correct width of the composed character.
3047 Reverse the sign of the DU offset produced by ScriptPlace.
3049 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
3051 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
3053 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
3055 Avoid direct writes to contents member of struct Lisp_Vector.
3056 * lisp.h (vcopy): New function to copy data into vector.
3057 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
3058 * fns.c (Ffillarray): Use ASET.
3059 * keyboard.c (timer_check_2): Use AREF and ASET.
3060 (append_tool_bar_item, Frecent_keys): Use vcopy.
3061 * lread.c (read_vector): Use ASET.
3062 * msdos.c (Frecent_doskeys): Use vcopy.
3063 * xface.c (Finternal_copy_lisp_face): Use vcopy.
3064 (Finternal_merge_in_global_face): Use ASET and vcopy.
3065 * xfont.c (xfont_list_pattern): Likewise.
3067 2012-08-21 Martin Rudalics <rudalics@gmx.at>
3069 * window.c (Fwindow_point): For the selected window always return
3070 the position of its buffer's point.
3071 (Fset_window_point): For the selected window always go in its
3072 buffer to the specified position.
3074 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
3076 Setter macros for fontsets.
3077 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
3078 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
3079 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
3082 2012-08-20 Glenn Morris <rgm@gnu.org>
3084 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
3085 Don't assume that `ln -f' works.
3087 2012-08-20 Eli Zaretskii <eliz@gnu.org>
3089 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
3090 and later about non-assignments with no effect. See discussion at
3091 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
3094 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
3096 Inline setter functions for Lisp_Objects slots of struct specbinding.
3097 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
3100 2012-08-20 Martin Rudalics <rudalics@gmx.at>
3102 * window.c (select_window): Always make selected window's buffer
3105 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
3107 Use AREF and ASET for docstrings of category tables.
3108 * category.h (CATEGORY_DOCSTRING): Use AREF.
3109 (SET_CATEGORY_DOCSTRING): Use ASET.
3110 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
3112 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
3114 Inline setter functions for hash table members.
3115 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
3116 (set_hash_hash, set_hash_index): Rename with _slot suffix.
3117 (set_hash_key_and_value, set_hash_index, set_hash_next)
3118 (set_hash_hash): New functions.
3119 * charset.c, fns.c: Adjust users.
3121 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
3123 Inline getter and setter functions for per-buffer values.
3124 * buffer.h (per_buffer_default, set_per_buffer_default)
3125 (per_buffer_value, set_per_buffer_value): New functions.
3126 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
3127 * buffer.c, data.c: Adjust users.
3129 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
3131 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
3133 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
3135 Rely on <config.h> + <unistd.h> to declare 'environ',
3136 as gnulib does this if the system doesn't.
3137 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
3138 Remove declaration. MS-Windows declares it on stdlib.h which is
3139 included by conf_post.h.
3140 * emacs.c (environ) [DOUG_LEA_MALLOC]:
3141 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
3142 * vm-limit.c: Include <unistd.h>, for 'environ'.
3144 * unexaix.c, unexcoff.c: Include "mem-limits.h".
3145 (start_of_data): Remove decl; mem-limits.h provides it.
3147 * xdisp.c (handle_invisible_prop): Make it a bit faster
3148 and avoid a gcc -Wmaybe-uninitialized diagnostic.
3150 2012-08-19 Chong Yidong <cyd@gnu.org>
3152 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
3155 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
3157 * .gdbinit: Use call instead of set when calling a function in the
3160 * data.c (set_internal): Don't use set_blv_found.
3161 (Fkill_local_variable): Likewise.
3163 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
3165 * nsfont.m (ns_ascii_average_width): Ensure the string
3166 ascii_printable is initialized with a null-terminated character
3167 array. Otherwise, it can contain undesired extra characters.

3561 Use bool, not int, for Lisp booleans.
3562 This is more natural, and on my platform (GCC 4.7.1 x86-64) it

4042 Export DEFAULT_REHASH_* to GDB.
4043 * lisp.h (DEFAULT_REHASH_THRESHOLD, DEFAULT_REHASH_SIZE):
4044 Now constants, not macros.
4046 2012-08-03 Paul Eggert <eggert@cs.ucla.edu>
4048 Remove unnecessary casts involving pointers.
4049 These casts are no longer needed now that we assume C89 or later,
4050 since they involve casting to or from void *.
4051 * alloc.c (make_pure_string, make_pure_c_string, pure_cons)
4052 (make_pure_float, make_pure_vector):
4053 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP):

4063 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
4064 Remove unnecessary pointer casts.
4065 * alloc.c (record_xmalloc): New function.
4066 * lisp.h (record_xmalloc): New decl.
4067 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
4068 more like a function. This is because the pointer cast is not
4069 needed. All uses changed.
4070 * print.c (print_string, print_error_message): Avoid length recalc.
4072 Improve fix for macroexp crash with debugging (Bug#12118).
4073 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
4074 ARRAY_MARK_FLAG when checking subscripts, because ASET is
4075 not supposed to be invoked from the garbage collector.
4076 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
4077 (gc_aset): New function, which is like ASET but can be
4078 used in the garbage collector.
4079 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)

4092 (map_w32_filename): Improve commentary. Simplify switch.
4093 (SYMBOLIC_LINK_FLAG_DIRECTORY): Define if not defined in system
4094 headers (most versions of MinGW w32api don't).
4095 (get_security_info, create_symbolic_link)
4096 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
4098 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
4099 in the argument file name.

4107 with addition of handling of symlinks and support for 'lstat'.
4108 If possible, get file's attributes and security information by
4109 handle, not by name. Produce S_IFLNK bit for symlinks, when
4110 called from 'lstat'.
4111 (stat, lstat): New functions, call 'stat_worker'.
4112 (symlink, readlink, careadlinkat): Rewritten to create and resolve
4113 symlinks when the underlying filesystem supports them.
4115 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
4117 Fix macroexp crash on Windows with debugging (Bug#12118).
4118 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
4119 checking subscripts; problem introduced with the recent
4120 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
4121 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
4122 since it's used in non-static inline functions now.
4124 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
4125 Don't assume buffer size fits in 'int'. Remove unused local.

4139 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
4140 * alloc.c (LISP_INLINE):
4141 * buffer.c (BUFFER_INLINE):
4142 * category.c (CATEGORY_INLINE):
4143 * character.c (CHARACTER_INLINE):
4144 * charset.c (CHARSET_INLINE):
4145 * composite.c (COMPOSITE_INLINE):
4146 * dispnew.c (DISPEXTERN_INLINE):
4147 * sysdep.c (SYSTIME_INLINE):
4148 Define to EXTERN_INLINE, so that the corresponding functions
4149 are compiled into code.
4150 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
4151 (INLINE_HEADER_END): New macros.
4152 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

4172 hard-coding the path separator.
4174 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
4176 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
4177 This how ASET and AREF are supposed to work, and makes
4178 it easier to think about future improvements. See
4179 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
4180 * charset.h (set_charset_attr): New function.
4181 All lvalue-style uses of CHARSET_DECODER etc. changed to use it.
4182 * lisp.h (ASET): Rewrite so as not to use AREF in an lvalue style.

4595 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
4596 enumeration constants, as PURE and HEAP are too general, and clash
4597 with other headers and sources, such as gmalloc.c and the
4598 MS-Windows system headers. All users changed.
4600 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
4602 Revert last save_excursion_save and save_excursion_restore changes.
4603 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

4616 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
4617 arms of an 'if', not using conditional expressions; otherwise GDB
4618 complains about the types in the unevaluated arm when the argument
4619 is an integer literal.
4620 (xgetint): Simplify expression.
4621 * alloc.c (gdb_make_enums_visible): New constant. This ports to
4622 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
4623 Zaretskii in <http://bugs.gnu.org/12036#13>.
4624 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
4625 needed now that we have gdb_make_enums_visible.
4626 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
4627 (enum enum_USE_LSB_TAG):
4628 New enum types, packaging up enums that need to be exported to GDB.

4670 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
4671 emacs.c, as this is a more-suitable home. Had this been done earlier
4672 the fix for 12036 would have avoided some of the problems noted in
4673 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
4674 would have been more obvious.
4675 * emacs.c: Do not include <verify.h>; no longer needed.
4676 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
4677 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
4678 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):

4683 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
4684 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
4685 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
4686 not be usable in #if. This simplifies things.
4688 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
4690 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.

4695 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
4696 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
4697 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
4698 Adjust to changes in lisp.h and emacs.c, by using
4699 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
4700 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
4701 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
4702 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
4703 instead of gdb_valbits.
4704 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
4705 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
4706 instead of gdb_array_mark_flag.
4707 (xboolvector): Get size from $->size, not $->header.size.
4708 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
4709 (xreload, hook-run, hookpost-run): Remove.
4710 * emacs.c: Include <verify.h>.
4711 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
4712 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
4714 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
4715 (gdb_USE_LSB_TAG): New enum constants.
4716 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
4717 Also define these as enum constants, so they're visible to GDB.
4718 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
4719 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
4720 as constants, so they're visible to GDB.

4723 Now enum constants, not macros, so they're visible to GDB.
4724 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
4725 more convenient now. All uses changed.
4726 (VALMASK) [USE_LSB_TAG]: Also define in this case.

4736 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
4737 add argument, tune behavior, and adjust all callers.
4739 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
4741 Use typedef for EMACS_INT, EMACS_UINT.
4742 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
4743 than macros. This simplifies debugging in the usual case, since
4744 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
4745 and it allows expressions involving EMACS_INT casts.
4746 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
4748 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

4760 Adjust buffer text indirection counters at the end of Fkill_buffer.
4761 * buffer.c (Fkill_buffer): Adjust indirection counters when the
4762 buffer is definitely dead. This should really fix an issue reported
4763 by Christoph Scholtes again. (Bug#12007).
4764 (init_buffer_once): Initialize indirection counters of
4765 buffer_defaults and buffer_local_symbols (for sanity and safety).
4767 2012-07-24 Eli Zaretskii <eliz@gnu.org>
4769 * xdisp.c (init_iterator): Don't compute dimensions of truncation
4770 and continuation glyphs on tooltip frames, leave them at zero.

4798 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
4800 Swap buffer text indirection counters in Fbuffer_swap_text.
4801 * buffer.c (Fbuffer_swap_text): Swap indirections too.
4802 This avoids crash reported by Christoph Scholtes at
4803 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
4805 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
4807 * nsmenu.m (Popdown_data): New struct.
4808 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
4810 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
4811 (initWithContentRect): Make imgView and contentView non-static
4812 and autorelease them. Also autorelease img and matrix (Bug#12005).
4813 (dealloc): Remove (Bug#12005).
4815 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
4817 Adjust consing_since_gc when objects are explicitly freed.

4830 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
4832 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
4833 as it's limited by the amount of memory, not by INT_MAX.
4835 2012-07-21 Eli Zaretskii <eliz@gnu.org>
4837 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
4838 in special-event-map. See the discussion at

5383 and continuation glyphs alike.
5384 (produce_special_glyphs) [HAVE_WINDOW_SYSTEM]: Produce a stretch
5385 glyph of a suitably computed width, to align the special glyphs at
5386 the window margin. Code moved from display_line. (Bug#11832)

5561 * s/aix4-2.h (unix): Remove; no longer needed.
5563 EMACS_TIME simplification (Bug#11875).
5564 This replaces macros (which typically do not work in GDB)
5565 with functions, typedefs and enums, making the code easier to debug.
5566 The functional style also makes code easier to read and maintain.
5567 * systime.h: Include <sys/time.h> on all hosts, not just if
5568 WINDOWSNT, since 'struct timeval' is needed in general.

5584 (add_emacs_time, sub_emacs_time): New functions.
5585 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.

5608 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
5609 Prefer snprintf to strncpy.
5610 * nsterm.m (ns_term_init):
5611 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
5612 * nsterm.m (ns_term_init):
5613 Avoid the need for strncpy, by using build_string or
5614 make_unibyte_string directly. Use dtoastr, not snprintf.
5615 * process.c (Fmake_network_process): Diagnose service names that
5616 are too long, rather than silently truncating them or creating
5617 non-null-terminated names.

5634 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
5635 where argument type is known to be a Lisp_Cons.

5690 O_RDONLY already includes it).
5692 Stop ns builds setting the EMACSLOADPATH environment variable.
5693 * nsterm.m (ns_load_path): Rename from ns_init_paths.
5694 Now it does not set EMACSLOADPATH, just returns the load-path string.

5696 * lread.c [HAVE_NS]: Include nsterm.h.
5697 (init_lread) [HAVE_NS]: Use ns_load_path.

5707 (ns_init_paths): Do not set EMACSPATH.

5767 Move marker debugging code under MARKER_DEBUG.
5768 * marker.c (MARKER_DEBUG): Move marker debugging code under
5769 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
5770 for bootstrap with --enable-checking (~3x slowdown reported

5816 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
5817 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
5818 Fix pointer signedness problem.
5819 * xfaces.c (FRAME_X_FONT_TABLE):
5820 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
5822 2012-07-07 Glenn Morris <rgm@gnu.org>
5824 * lread.c (load_path_check): New function, split from init_lread.
5825 (init_lread): Reorganize. Motivation:
5826 If EMACSLOADPATH is set, check/warn about that rather than the
5827 defaults, which we are not going to use. Hence we can remove
5828 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
5829 Don't warn if site-lisp directories are missing.
5830 If not installed, start from a blank load-path, since
5831 PATH_LOADSEARCH refers to the eventual installation directories.
5833 2012-07-07 Eli Zaretskii <eliz@gnu.org>
5835 Support truncation and continuation glyphs on GUI frames, when
5836 fringes are disabled. (Bug#11832)
5837 * xdisp.c (init_iterator): Get dimensions of truncation and
5838 continuation glyphs even if on GUI frames.
5839 Adjust it->last_visible_x on GUI frames when the left or right fringes,
5840 or both, are absent.
5841 (start_display, move_it_in_display_line_to): Handle the case of a
5842 GUI frame without a fringe to display continuation or truncation
5844 (insert_left_trunc_glyphs): Support GUI frames: make sure
5845 truncation glyphs overwrite enough glyphs from the current line to
5846 have sufficient space in pixels.
5847 (display_line): Support truncation and continuation glyphs on GUI
5848 frames. If some spare pixels are left on the line after inserting
5849 the truncation glyphs, fill that space with a stretch glyph of a
5850 suitably computed width.
5852 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
5853 produce_glyphs, to support GUI sessions.
5855 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
5857 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
5859 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
5861 Do not require float-time's arg to fit in time_t (Bug#11825).
5862 This works better on hosts where time_t is unsigned, and where
5863 float-time is applied to the (negative) difference between two times.
5864 * editfns.c (decode_time_components): Last arg is now double *,
5865 not int *, and means to store all the result as a double, without
5866 worrying about whether the seconds part fits in time_t.
5867 All callers changed.
5868 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
5869 All callers changed.
5870 (Ffloat_time): Do not fail merely because the specified time falls
5871 outside of time_t range.
5873 2012-07-07 Glenn Morris <rgm@gnu.org>
5875 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
5876 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):

5882 Update dependencies.
5884 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
5886 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
5888 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
5889 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
5890 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
5891 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
5892 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
5893 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
5895 * xfont.c (compare_font_names): Redo to omit the need for casts.
5897 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
5899 * xfns.c (Fx_change_window_property): Doc fix.
5900 * w32fns.c (Fx_change_window_property): Doc fix.
5902 * w32fns.c (Fx_window_property): Accept the same arguments as the
5903 X Windows version. Doc fix.
5904 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
5906 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
5907 Eli Zaretskii <eliz@gnu.org>
5909 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
5910 Windows-specific code from nt/config.nt moved here.
5911 Obsolete settings removed.
5913 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
5915 * process.c: Avoid unnecessary calls to gettime.
5916 (wait_reading_process_output): Don't get the time of day
5917 when gobbling data immediately and not waiting, as there's no need
5918 for it in that case. This removes a FIXME.
5920 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
5922 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
5923 is defined (Bug#11768).
5925 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
5927 Fix marker debugging code.
5928 * marker.c (byte_char_debug_check): Do not perform the check
5929 if buffer is not multibyte.
5930 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
5931 Call byte_char_debug_check with correct arguments.
5933 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
5935 Compile marker debugging code only if ENABLE_CHECKING is defined.
5936 * marker.c (byte_char_debug_check, count_markers):
5937 Use only if ENABLE_CHECKING is defined.
5938 (byte_debug_flag): Remove.
5939 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
5940 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
5942 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
5944 Avoid code repetition in marker-related functions.
5945 * marker.c (attach_marker): New function.
5946 (Fset_marker, set_marker_restricted, set_marker_both)
5947 (set_marker_restricted_both): Use it.
5948 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
5949 Consistently rename charno to charpos.
5950 (marker_position): Add eassert.
5951 (marker_byte_position): Convert to eassert.
5953 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
5955 Simplify list operations in unchain_overlay and unchain_marker.

5959 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
5961 Introduce fast path for the widely used marker operation.
5962 * alloc.c (build_marker): New function.
5963 * lisp.h (build_marker): New prototype.
5964 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
5965 * composite.c (autocmp_chars): Likewise.
5966 * editfns.c (buildmark): Remove.
5967 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
5968 (save_restriction_save): Use build_marker.
5969 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
5970 * window.c (save_window_save): Likewise.
5972 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
5974 Do not use Fdelete_overlay in delete_all_overlays
5975 to avoid redundant calls to unchain_overlay.
5976 * buffer.c (drop_overlay): New function.
5977 (delete_all_overlays, Fdelete_overlay): Use it.
5978 * minibuf.c (get_minibuffer): Fix comment.
5980 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
5982 Port to OpenBSD 5.1 amd64.
5983 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
5984 This is needed for OpenBSD, and should be harmless on all BSD systems.
5985 Also, include <sys/sysctl.h>, as it should be available on all
5986 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
5987 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
5988 use p_pid member, not kp_proc.pid.
5990 2012-07-06 Glenn Morris <rgm@gnu.org>
5992 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
5994 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
5996 More xmalloc and related cleanup.
5997 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
5998 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:
5999 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, fns.c:

6003 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:
6004 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
6005 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
6007 Omit needless casts involving void * pointers and allocation.
6008 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
6009 as the former is more robust if P's type is changed.
6010 Prefer xzalloc to xmalloc + memset 0.
6011 Simplify malloc-or-realloc to realloc.
6012 Don't worry about xmalloc returning a null pointer.
6013 Prefer xstrdup to xmalloc + strcpy.
6014 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
6016 * keyboard.c (apply_modifiers_uncached): Prefer local array to
6017 alloca of a constant.
6019 2012-07-05 Eli Zaretskii <eliz@gnu.org>
6021 * xdisp.c (display_line): Fix horizontal pixel coordinates when
6022 hscroll is larger than the line width. Fixes long and futile
6023 looping inside extend_face_to_end_of_line (on a TTY) producing
6024 glyphs that are not needed and thrown away.
6026 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
6028 * marker.c (set_marker_restricted_both): Simplify by using
6031 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
6033 * editfns.c (region_limit): Simplify by using clip_to_bounds.
6035 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
6037 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
6038 not defined (Bug#11768).
6039 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
6040 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
6041 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
6042 followed by gtk_box_set_homogeneous (Bug#11768).
6043 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
6044 (update_theme_scrollbar_width, xg_create_scroll_bar):
6045 Use gtk_scrollbar_new (Bug#11768).
6046 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
6047 (is_box_type): New function (Bug#11768).
6048 (xg_tool_item_stale_p): Call is_box_type.
6049 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
6050 with default display (Bug#11768).
6052 2012-07-05 Eli Zaretskii <eliz@gnu.org>
6054 * xdisp.c (window_hscroll_limited): New function.
6055 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
6056 coordinates when window's hscroll is set to insanely large
6059 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
6061 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
6062 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
6064 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
6067 * lisp.h (xzalloc): New prototype. Omit needless casts.
6068 * alloc.c (xzalloc): New function. Omit needless casts.

6120 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
6122 * fileio.c (time_error_value): Check the right error number.
6123 Problem reported by Troels Nielsen in
6124 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
6126 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
6128 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
6129 This should be fixed in a better way; see Eli Zaretskii in
6130 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
6131 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
6133 * fileio.c (time_error_value): Rename from special_mtime.
6134 The old name's problems were noted by Eli Zaretskii in
6135 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
6137 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
6138 This variable's comment says Emacs needs at least one GDB-visible
6139 symbol of type enum pvec_type, to work around GDB problems.
6140 The symbol's value doesn't matter.
6142 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
6143 that causes compilation to fail on pre-C99 compilers.
6145 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
6147 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
6148 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
6150 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
6152 * buffer.c (init_buffer_once): Fix initialization of
6153 headers for buffer_defaults and buffer_local_symbols.
6154 Reported by Juanma Barranquero <lekktu@gmail.com>.
6156 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
6158 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
6159 * lisp.h (enum pvec_type): Use fewer bits.
6160 (PSEUDOVECTOR_SIZE_BITS): New constant.
6161 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
6162 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
6163 change in pvec_type.
6164 (PSEUDOVECTOR_TYPEP): New macro.
6165 (TYPED_PSEUDOVECTORP): Use it.
6166 * fns.c (internal_equal): Adapt code to extract pvectype.
6167 * emacs.c (gdb_pvec_type): Update type.
6168 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
6169 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
6170 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
6171 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
6172 (sweep_vectors): Use it. Use local var `total_bytes' instead of
6173 abusing vector->header.next.nbytes.
6174 (live_vector_p): Use PVEC_TYPE.
6175 (mark_object): Adapt code to extract pvectype. Use switch.
6177 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
6179 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
6180 Tighten new eassert a bit.
6182 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
6184 Fix compilation with --enable-gcc-warnings and -O1
6186 * doprnt.c (doprnt): Change type of tem to int, initialize
6187 to avoid compiler warning. Add eassert.
6188 * search.c (simple_search): Initialize match_byte to avoid
6189 compiler warning. Add eassert.
6191 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
6193 Avoid weird behavior with large horizontal scrolls.
6194 Without this change, for example, large hscroll values would
6195 mess up Emacs's display on Fedora 15 x86, presumably due to
6196 overflows in int calculations in the display code.
6197 Also, if buffers had long lines, Emacs would freeze.
6198 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
6199 (set_window_hscroll): New function, containing the old guts of
6200 Fset_window_hscroll. Return the clipped value.
6201 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
6202 This avoids the need to check against PTRDIFF_MAX.
6204 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
6206 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
6208 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
6210 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
6212 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
6213 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
6214 since GCC 4.4.6 issues a bogus warning for them.
6216 Fix bugs in file timestamp newness comparisons.
6217 * fileio.c (Ffile_newer_than_file_p):
6218 * lread.c (Fload): Use full timestamp resolution of files,
6219 not just the 1-second resolution, so that files that are only
6220 slightly newer still count as newer.
6221 * fileio.c (Ffile_newer_than_file_p): Don't assume file
6222 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
6224 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
6226 * fileio.c: Improve handling of file time marker. (Bug#11852)
6227 (special_mtime): New function.
6228 (Finsert_file_contents, Fverify_visited_file_modtime):
6229 Use it to set special mtime values consistently.
6231 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
6233 * fileio.c (Finsert_file_contents): Properly handle st_mtime
6234 marker for non-existing file. (Bug#11852)
6236 2012-07-03 Glenn Morris <rgm@gnu.org>
6238 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
6239 and did not make it into globals.h).
6241 2012-07-03 Tom Tromey <tromey@redhat.com>

6288 values which aren't power of 2.
6289 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
6290 Verify it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
6293 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
6295 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.

6299 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
6301 * alloc.c (allocate_vector_block): Remove redundant
6302 calls to mallopt if DOUG_LEA_MALLOC is defined.
6303 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
6304 avoid calls to mallopt if zero_vector is returned.
6306 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
6308 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
6309 is enabled, avoid dereferencing NULL current_sblock if
6312 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
6314 Cleanup basic buffer management.
6315 * buffer.h (struct buffer): Change layout to use generic vector
6316 marking code. Fix some comments. Change type of 'clip_changed'
6317 to bitfield. Remove unused #ifndef old.

6319 (GET_OVERLAYS_AT): Fix indentation.
6320 (for_each_per_buffer_object_at): New macro.
6321 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)

6324 * alloc.c (allocate_buffer): Adjust to match new layout of
6325 struct buffer. Fix comment.
6326 (mark_overlay): New function.

6328 Lisp area of struct buffer.
6329 (mark_object): Use it. Adjust marking of misc objects
6330 and related comments.
6332 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
6334 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
6335 wrapper that is not needed because the wrapped code is a no-op (zero
6336 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
6337 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
6339 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
6341 * alloc.c (mark_buffer): Simplify. Remove prototype.
6342 (mark_object): Add comment. Reorganize marking of vector-like
6343 objects. Use CHECK_LIVE for all vector-like objects except buffers
6344 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
6345 Avoid redundant calls to mark_vectorlike for bool vectors.
6347 2012-06-30 Glenn Morris <rgm@gnu.org>
6349 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
6351 * epaths.in (PATH_SITELOADSEARCH): New.
6352 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
6353 This is rather than relying on --enable-locallisppath elements
6354 having "site-lisp" in their names. (Bug#10208#25, 11658)
6356 2012-06-30 Eli Zaretskii <eliz@gnu.org>
6358 * w32proc.c (sys_select): Accept and ignore one more argument.
6360 * w32.c (emacs_gnutls_pull): Call select with one more argument.
6362 * sysselect.h [DOS_NT]: Don't include sys/select.h.
6363 (pselect) [!MS_DOS]: Redirect to sys_select.
6365 * sysdep.c: Don't include dos.h and dosfns.h.
6367 * process.c (sys_select):
6368 * msdos.c (sys_select): Accept one more argument and ignore it.
6370 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
6371 adapt data types and code to that.
6374 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
6375 which clashes with the gnulib function of the same name.
6377 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
6379 * font.c (font_style_to_value, font_style_symbolic)
6380 (font_prop_validate_style): Add type checks for values in
6383 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
6385 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
6388 2012-06-29 Eli Zaretskii <eliz@gnu.org>
6390 * xdisp.c (try_window_id): Undo last change.
6392 * w32.c (getwd): Adjust commentary about startup_dir.
6393 (init_environment): Always call sys_access, even in non-MSVC
6394 builds. Don't chdir to the directory of the Emacs executable.
6395 This undoes code from 1997 which was justified by the need to
6396 "avoid conflicts when removing and renaming directories". But its
6397 downside was that every relative file name was being interpreted
6398 relative to the directory of the Emacs executable, which can never
6399 be TRT. In particular, it broke sys_access when called with
6400 relative file names.
6401 (sys_access): Map GetLastError to errno.
6403 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
6405 * window.h (struct window): Change type of 'fringes_outside_margins'

6409 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
6412 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>

6415 Add QUIT to make the loop interruptible.
6417 2012-06-29 Glenn Morris <rgm@gnu.org>
6419 * charset.c (init_charset): Make lack of etc/charsets fatal.
6421 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
6423 * editfns.c (region_limit): Fix type mismatch.
6425 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
6427 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
6428 undefined. Convert from xassert to eassert.
6429 * nsmenu.m: Convert from xassert to eassert.

6436 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
6438 Avoid integer overflow on scroll-left and scroll-right.
6439 * window.c (HSCROLL_MAX): New macro.
6440 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer

6445 * window.h (struct window): Change type of 'hscroll',
6446 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
6447 'last_modified' and 'last_overlay_modified' to EMACS_INT.
6448 Adjust users accordingly.
6449 * xdisp.c (try_cursor_movement): Replace type check with eassert.
6450 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
6451 from EMACS_INT to ptrdiff_t.
6452 (make_window): Omit redundant initialization.
6454 2012-06-28 Juanma Barranquero <lekktu@gmail.com>

6458 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
6460 * window.h (struct window): Change type of 'use_time' and

6527 * alloc.c (allocate_string): Omit intervals initialization.
6528 * alloc.c (make_uninit_multibyte_string): Initialize intervals
6529 as in make_pure_string and make_pure_c_string.

6587 a better opportunity to optimize away calls to strlen when the
6588 function is called with compile-time constant argument.
6589 * image.c (imagemagick_error): Convert to build_string.
6590 * w32proc.c (sys_spawnve): Likewise.

6593 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
6595 Use sprintf return value instead of invoking strlen on result.
6596 In the old days this wasn't portable, since some sprintf
6597 implementations returned char *. But they died out years ago and
6598 Emacs already assumes sprintf returns int.
6599 Similarly for float_to_string.
6600 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

6607 * xfns.c (syms_of_xfns):
6608 Use sprintf or float_to_string result to avoid need to call strlen.
6609 * data.c (Fnumber_to_string):
6610 Use make_unibyte_string, since the string must be ASCII.
6611 * lisp.h, print.c (float_to_string): Now returns int length.
6612 * term.c (produce_glyphless_glyph):
6613 Use sprintf result rather than recomputing it.
6615 Clean out last vestiges of the old HAVE_CONFIG_H stuff.

6646 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
6648 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

6651 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
6653 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
6654 instead of truncating it to 63 (admittedly a generous limit).
6656 * process.c: Fix spelling and caps in comments.
6658 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>

6714 * keyboard.c (kbd_buffer_get_event):

6779 (timeval_to_EMACS_TIME) [__FreeBSD__]: New static function.
6780 (TIMEVAL) [__FreeBSD__]: Now a static function rather than a macro.
6781 (TIMEVAL, system_process_attributes) [__FreeBSD__]:
6782 Don't assume EMACS_TIME and struct timeval are the same type.
6784 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
6786 Support higher-resolution time stamps (Bug#9000).
6787 The time stamps are only nanosecond-resolution at the C level,
6788 since that's the best that any real-world system supports now.
6789 But they are picosecond-resolution at the Lisp level, as that's
6790 easy, and leaves room for future OS improvements.
6792 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
6795 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
6796 Don't get current time unless it's needed.
6798 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
6799 now provides it if it's absent.
6800 (start_atimer): Port to higher-res time stamps.
6801 Check for time stamp overflow. Don't get current time more
6802 often than is needed.
6804 * buffer.h (struct buffer): Buffer modtime now has high resolution.
6805 Include systime.h, not time.h.
6806 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
6808 * dired.c: Include stat-time.h.
6809 (Ffile-attributes): File times now have higher resolution.
6811 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
6812 (struct image): Timestamp now has higher resolution.
6814 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
6815 has at least microseconds now. All uses removed.
6816 (update_frame, update_single_window, update_window, update_frame_1)
6817 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
6818 (duration_to_sec_usec): Remove; no longer needed.
6820 * editfns.c (time_overflow): Now extern.
6821 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
6822 (float-time, Fformat_time_string, Fcurrent_time_string)
6823 (Fcurrent_time_zone): Accept and generate higher-resolution
6825 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
6826 (decode_time_components, lisp_seconds_argument): New functions.
6827 (make_time): Now static.
6828 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
6829 Report an error if the time is invalid, rather than having the caller
6832 * fileio.c: Include <stat-time.h>
6833 (Fcopy_file): Copy higher-resolution time stamps.
6834 Prefer to set the time stamp via a file descriptor if that works.
6835 (Fset_file_times, Finsert_file_contents, Fwrite_region)
6836 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
6837 (Fvisited_file_modtime, Fset_visited_file_modtime):
6838 Support higher-resolution time stamps.
6840 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
6842 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
6844 * image.c (prepare_image_for_display, clear_image_cache)
6845 (lookup_image): Port to higer-resolution time stamps.
6847 * keyboard.c (start_polling, bind_polling_period):
6848 Check for time stamp overflow.
6849 (read_char, kbd_buffer_get_event, timer_start_idle)
6850 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
6851 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
6852 Port to higher-resolution time stamps. Do not assume time_t is signed.
6853 (decode_timer): New function. Timers are now vectors of length 9,
6854 not 8, to accommodate the picosecond component.
6855 (timer_check_2): Use it.
6857 * nsterm.m (select_timeout, timeval_subtract): Remove.
6858 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
6859 as they're a bit more accurate and handle overflow better.
6860 (ns_select): Change prototype to be compatible with pselect.
6861 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
6862 * nsterm.h (ns_select): Adjust prototype.
6864 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
6865 us-resolution time stamps.
6866 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
6868 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
6870 * lisp.h (time_overflow): New decl.
6871 (wait_reading_process_output): First arg is now intmax_t, not int,
6872 to accommodate larger waits.
6874 * process.h (struct Lisp_Process.read_output_delay):
6875 Now counts nanoseconds, not microseconds.
6876 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
6878 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
6879 (wait_reading_process_output):
6880 Port to ns-resolution time stamps.
6881 (Faccept_process_output, wait_reading_process_output):
6882 Check for time stamp overflow. Do not assume time_t is signed.
6883 (select_wrapper): Remove; we now use pselect.
6884 (Fprocess_attributes): Now generates ns-resolution time stamps.
6886 * sysdep.c: Include utimens.h. Don't include utime.h
6887 or worry about struct utimbuf; gnulib does that for us now.
6888 (gettimeofday): Remove; gnulib provides a substitute.
6889 (make_timeval): New function.
6890 (set_file_times): Now sets ns-resolution time stamps.
6891 New arg FD; all uses changed.
6892 (time_from_jiffies, ltime_from_jiffies, get_up_time)
6893 (system_process_attributes):
6894 Now returns ns-resolution time stamp. All uses changed.
6895 Check for time stamp overflow.
6897 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
6898 provides a substitute now.
6900 * systime.h: Include timespec.h rather than sys/time.h and time.h,
6901 since it guarantees struct timespec.
6902 (EMACS_TIME): Now struct timespec, so that we can support
6903 ns-resolution time stamps.
6904 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
6905 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
6906 (EMACS_USECS): Remove.
6907 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
6908 so multiply the arg by 1000 before storing it.
6909 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
6911 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
6912 Port to ns-resolution time stamps.
6913 (EMACS_TIME_NEG_P): Remove; replaced by....
6914 (EMACS_TIME_SIGN): New macro.
6915 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
6916 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
6917 (set_file_times, make_time, lisp_time_argument): Adjust signature.
6918 (make_timeval, make_lisp_time, decode_time_components): New decls.
6919 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
6920 that it mishandled time_t overflow. You can't compare by subtracting!
6921 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
6922 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
6924 * term.c: Include <sys/time.h>.
6925 (timeval_to_Time): New function, for proper overflow wraparound.
6926 (term_mouse_position, term_mouse_click): Use it.
6928 * undo.c (record_first_change): Support higher-resolution time stamps
6930 (Fprimitive_undo): Use them when restoring time stamps.
6932 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
6933 (w32_get_internal_run_time):
6934 Port to higher-resolution Emacs time stamps.
6935 (ltime): Now accepts single 64-bit integer, as that's more convenient
6938 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
6940 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
6941 for compatibility with pselect. Support ns-resolution time stamps.
6943 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
6945 * xselect.c (wait_for_property_change, x_get_foreign_selection):
6946 Check for time stamp overflow, and support ns-resolution time stamps.
6948 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
6949 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
6950 (timeval_subtract): Remove; no longer needed.
6951 (XTflash, XTring_bell, x_wait_for_event):
6952 Port to ns-resolution time stamps. Don't assume time_t is signed.
6954 2012-06-22 Chong Yidong <cyd@gnu.org>
6956 * xdisp.c (x_consider_frame_title): Revert last change.
6958 2012-06-22 Eli Zaretskii <eliz@gnu.org>
6960 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
6961 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
6962 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
6963 staticidx goes up to 1597 out of 1600 = 0x640.)
6965 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
6967 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
6968 Otherwise, the umask might be mistakenly 0 while handling input signals.
6970 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
6972 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

6978 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
6979 access to `contents' member of Lisp_Vector objects with AREF and ASET
6982 2012-06-19 Chong Yidong <cyd@gnu.org>
6984 * frame.c (delete_frame): When selecting a frame on a different
6985 text terminal, do not alter the terminal's top-frame.

6989 (unwind_format_mode_line): Restore them.
6990 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
6992 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
6993 since tty frames can be explicitly named.
6994 (prepare_menu_bars): Likewise.
6996 * term.c (Ftty_top_frame): New function.
6998 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
7000 Port byte-code-meter to modern targets.
7001 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
7002 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
7003 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
7004 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
7005 (METER_1, METER_2): Simplify.
7007 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>

7011 2012-06-18 Martin Rudalics <rudalics@gmx.at>
7013 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
7014 gets killed during executing of this function (Bug#11665).
7015 Try to always return Qt when the buffer has been actually killed.
7016 (Vkill_buffer_query_functions): In doc-string say that functions
7017 run by this hook should not change the current buffer.
7019 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
7021 Fix recently-introduced process.c problems found by static checking.
7022 * process.c (write_queue_push, write_queue_pop, send_process):

7039 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
7041 * lisp.h (eassert): Assume C89 or later.
7042 This removes the need for CHECK.
7043 (CHECK): Remove. Its comments about always evaluating its
7044 argument were confusing, as 'eassert' typically does not evaluate
7047 * coding.c (produce_chars): Use ptrdiff_t, not int.
7049 * xterm.c (x_draw_underwave): Check for integer overflow.
7050 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.
7052 2012-06-17 Jan Djärv <jan.h.d@swipnet.se>

7143 * xdisp.c (set_cursor_from_row): Don't dereference glyphs_end.
7144 If all the glyphs of the glyph row came from strings, and we have no
7145 cursor positioning clues, put the cursor on the first glyph of the

7232 USE_LSB_TAG now is always defined to be either 0 or 1.
7234 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
7235 code works fine either way, and efficiency is not a concern here,
7236 as the union type is for debugging, not for production.
7237 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
7238 Use an inline function on all platforms when using the union type,
7239 since this is simpler and 'static inline' can be used portably

7383 * doprnt.c (doprnt): Truncate multibyte char correctly.
7384 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
7385 would mishandle a string argument "Xc" if X was a multibyte
7386 character of length 2: it would truncate after X's first byte
7387 rather than including all of X.
7389 2012-06-06 Chong Yidong <cyd@gnu.org>
7391 * buffer.c (word_wrap): Doc fix.

7444 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
7446 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
7449 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
7451 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
7453 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
7455 For a 'struct window', replace some Lisp_Object fields to
7456 bitfields where appropriate, remove unused fields.
7457 * window.h (struct window): Remove unused 'last_mark_x' and
7458 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
7459 change it's type from Lisp_Object to bitfield.
7460 Change type of 'force_start', 'optional_new_start',
7461 'last_had_star', 'update_mode_line' and 'start_at_line_beg'

7464 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
7466 Pacify gcc -Wdouble-precision when using Xaw.

7468 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
7469 Use 'float' consistently, rather than 'float' in most places
7470 and 'double' in a couple of places.
7472 2012-05-31 Eli Zaretskii <eliz@gnu.org>
7474 * xdisp.c (handle_stop): Detect whether we have overlay strings
7475 loaded by testing it->current.overlay_string_index to be
7476 non-negative, instead of checking whether n_overlay_strings is
7477 positive. (Bug#11587)
7479 2012-05-31 Chong Yidong <cyd@gnu.org>
7481 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

7487 * search.c (search_buffer): Remove calls to
7488 r_alloc_inhibit_buffer_relocation, as it is now called by
7489 maybe_unify_char, which was the cause of relocation of buffer text
7492 2012-05-31 Eli Zaretskii <eliz@gnu.org>
7494 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
7495 for the duration of call to load_charset, to avoid problems with
7496 callers of maybe_unify_char that access buffer text through C
7499 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
7500 decrement the inhibition flag, instead of just setting or
7503 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
7505 Remove obsolete '#define static' cruft.
7506 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
7507 This #undef was "temporary" in 2000; it is no longer needed
7508 now that '#define static' has gone away.
7509 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
7510 (gray_bitmap_bits): Remove; no longer needed.
7511 All uses replaced with definiens.
7512 * xterm.c: Include "bitmaps/gray.xbm".
7514 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
7516 Clean up __executable_start, monstartup when --enable-profiling.
7517 The following changes affect the code only when profiling.
7518 * dispnew.c (__executable_start): Rename from safe_bcopy.
7519 Define only on platforms that need it.
7520 * emacs.c: Include <sys/gmon.h> when profiling.
7521 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.

7523 (safe_bcopy): Remove decl; no longer has that name.
7524 (main): Coalesce #if into single bit of code, for simplicity.

7554 Do not create empty overlays with the evaporate property (Bug#9642).
7555 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
7556 Bug#9642, but explicitly check that the buffer the overlay would
7557 be moved to is live and rearrange lines to make sure that errors
7558 will not put the overlay in an inconsistent state.
7559 (Fdelete_overlay): Cosmetics.
7561 2012-05-28 Eli Zaretskii <eliz@gnu.org>
7563 * w32term.c (my_bring_window_to_top): New function.

7577 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
7578 This avoids undefined behavior that might cause the eassert
7579 to not catch an out-of-range value.
7581 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
7583 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

7597 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
7598 Only r_alloc_inhibit_buffer_relocation needed to be added;
7599 the others were already declared.
7601 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
7602 before checking whether it's out of range. Put the check inside
7604 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
7606 2012-05-27 Ken Brown <kbrown@cornell.edu>

7614 defined on ralloc.c.
7616 * buffer.c [REL_ALLOC]: Remove prototypes of

7618 they are now on lisp.h.
7620 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
7622 * search.c (search_buffer): Use it to inhibit relocation of buffer
7623 text while re_search_2 is doing its job, because re_search_2 is
7624 passed C pointers to buffer text. (Bug#11519)
7626 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
7629 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator

7634 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
7637 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
7639 Fix coding-related core dumps with gcc -ftrapv.
7640 The code was computing A - B, where A and B are pointers, and B is
7641 random garbage. This can lead to core dumps on platforms that
7642 have special pointer registers, and it also leads to core dumps on
7643 x86-64 when compiled with gcc -ftrapv. The fix is to compute
7644 A - B only when B is initialized properly.
7645 * coding.c (coding_set_source, coding_set_destination): Return void.
7646 (coding_change_source, coding_change_destinations): New functions,
7647 with the old behaviors of coding_set_source and coding_set_destination.

7652 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
7654 2012-05-26 Eli Zaretskii <eliz@gnu.org>
7656 Extend mouse support on W32 text-mode console.
7657 * xdisp.c (draw_row_with_mouse_face):
7658 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
7660 * w32console.c: Include window.h.
7661 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
7663 (initialize_w32_display): Initialize mouse-highlight data.
7665 * w32inevt.c: Include termchar.h and window.h.
7666 (do_mouse_event): Support mouse-autoselect-window. When the mouse
7667 moves, call note_mouse_highlight. If help_echo changed, call
7668 gen_help_event to produce help-echo message in the echo area.
7669 Call clear_mouse_face if mouse_face_hidden is set in the mouse
7672 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
7674 * lread.c (read1): Simplify slightly to avoid an overflow warning
7675 with GCC 4.7.0 on x86-64.
7677 2012-05-26 Eli Zaretskii <eliz@gnu.org>

7695 (allocate_pseudovector):
7696 Use int, not EMACS_INT, where int is wide enough.
7697 (inhibit_garbage_collection, Fgarbage_collect):
7698 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
7699 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where

7717 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
7718 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
7719 (validate_region): Omit unnecessary test for b <= e,
7720 since that's guaranteed by the previous test.

7722 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
7723 (report_overlay_modification):
7724 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
7725 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):

7727 after the EMACS_INT -> ptrdiff_t change.
7728 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
7729 * buffer.h: Adjust decls to match defn changes elsewhere.

7734 not int, to avoid needless 32-bit limit on 64-bit hosts.
7735 (exec_byte_code): Use tighter memory-full test, one that checks
7736 for alloca overflow. Don't compute the address of the object just
7737 before an array, as that's not portable. Use EMACS_INT, not
7738 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
7739 * callint.c (Fcall_interactively):
7740 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

7753 (casify_object): Avoid integer overflow when overallocating buffer.
7754 * casetab.c (set_identity, shuffle): Prefer int to unsigned when

7757 * category.h (CATEGORYP): Don't assume arg is nonnegative.
7758 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
7759 integers are now checked earlier. All uses replaced with XINT.
7761 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
7762 For CCL_MapSingle, check that content and value are in int range.

7764 Check that Vcode_version_map_vector is a vector.
7765 (resolve_symbol_ccl_program): Check that vector header is in range.
7766 Always copy the vector, so that we can check its contents reliably
7767 now rather than having to recheck each instruction as it's being
7768 executed. Check that vector words fit in 'int'.
7769 (ccl_get_compiled_code, Fregister_ccl_program)
7770 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for

7797 Don't rely on undefined behavior with signed left shift overflow.
7798 Don't assume unsigned int fits into fixnum, or that fixnum fits
7799 into unsigned int. Don't require max_code to be a valid fixnum;
7800 that's not true for gb10830 4-byte on a 32-bit host. Allow
7801 invalid_code to be a cons, for the same reason. Require code_offset
7802 to be a character. Avoid int overflow if max_char is close
7804 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
7805 this is intended anyway and avoids some undefined behavior.
7806 (load_charset_map): Pass unsigned, not int, as 2nd arg of
7807 INDEX_TO_CODE_POINT, as that's what it expects.
7808 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
7809 * charset.h (DECODE_CHAR): Return int, not unsigned;
7810 this is what was intended anyway, and it avoids undefined behavior.
7811 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
7812 integer-overflow issues.
7813 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
7814 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
7815 where the argument is EMACS_INT, and this behavior is not intended.
7816 * chartab.c (Fmake_char_table, Fset_char_table_range)
7817 (uniprop_get_decoder, uniprop_get_encoder):
7818 Don't assume fixnum fits in int.
7819 * cmds.c (move_point): New function, that does the gist of
7820 Fforward_char and Fbackward_char, but does so while checking
7821 for integer overflow more accurately.
7822 (Fforward_char, Fbackward_char): Use it.
7823 (Fforward_line, Fend_of_line, internal_self_insert)
7824 (internal_self_insert):

8430 doesn't matter here.
8431 (get_next_display_element, next_element_from_display_vector):
8432 Use int, not EMACS_INT, when int is wide enough.

8484 2012-05-25 Glenn Morris <rgm@gnu.org>
8486 * lisp.mk (lisp): Update for more files being compiled now.
8488 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>
8490 * lread.c: Remove `read_pure' which makes no difference.
8491 (read_pure): Remove var.
8492 (unreadpure): Remove function.
8493 (readevalloop): Don't call read_list with -1 flag.

8508 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
8511 This directory predates autoconf and is no longer needed nowadays.
8512 Move its few remaining bits of functionality to where they're needed.
8513 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:

8522 (EMACS_UINT): Define unconditionally now.
8523 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
8524 (BITS_PER_EMACS_INT): New constants, replacing
8525 what used to be in config.h, but not useful in #if.
8526 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
8527 define them any more.
8528 (VAL_MAX): New macro.
8530 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
8531 BITS_PER_EMACS_INT, in #if.
8532 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
8533 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
8534 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
8535 * s/ms-w32.h (DATA_START):
8536 Move here from removed file m/intel386.h.
8537 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
8538 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
8540 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
8542 Assume C89 or later.

8552 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
8553 * xterm.c (input_signal_count): Assume volatile works.
8555 2012-05-21 Ken Brown <kbrown@cornell.edu>
8557 * xgselect.c (xg_select): Fix first argument in call to 'select'
8560 2012-05-20 Ken Brown <kbrown@cornell.edu>
8562 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
8563 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
8565 2012-05-19 Ken Brown <kbrown@cornell.edu>
8567 * xfns.c (x_in_use): Remove `static' qualifier.
8568 * xterm.h (x_in_use): Declare.
8569 * xgselect.c: Include xterm.h.
8570 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
8571 and `display_arg' (bug#9754).
8573 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
8575 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
8577 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
8578 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
8580 2012-05-18 Eli Zaretskii <eliz@gnu.org>
8582 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
8584 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
8585 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
8587 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
8588 reference to image_cache->refcount.
8589 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
8591 2012-05-17 Juri Linkov <juri@jurta.org>
8593 * search.c (Fword_search_regexp, Fword_search_backward)
8594 (Fword_search_forward, Fword_search_backward_lax)
8595 (Fword_search_forward_lax): Move functions to isearch.el
8596 (bug#10145, bug#11381).
8598 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
8600 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
8602 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
8604 * lread.c (init_obarray): Declare Qt and Qnil as special.
8606 2012-05-14 Glenn Morris <rgm@gnu.org>
8608 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
8609 Put "libexec" before "bin", for the sake of init_callproc_1.
8611 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
8613 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
8615 * unexaix.c: Port to more-recent AIX compilers.
8616 (report_error, report_error_1, make_hdr, copy_sym)
8617 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
8618 Make arguments const char *, not char *, to avoid violations of C
8619 standard and to fix some AIX warnings reported by Gilles Pion.
8621 2012-05-14 Eli Zaretskii <eliz@gnu.org>
8623 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
8624 already have overlays loaded.
8625 (handle_single_display_spec): Before returning without displaying
8626 fringe bitmap, synchronize the bidi iterator with the main display
8627 iterator, by calling iterate_out_of_display_property.
8628 (iterate_out_of_display_property): Detect buffer iteration by
8629 testing that it->string is a Lisp string.
8630 (get_next_display_element): When the current object is exhausted,
8631 and there's something on it->stack, call set_iterator_to_next to
8632 proceed with what's on the stack, instead of returning zero.
8633 (set_iterator_to_next): If called at the end of a Lisp string,
8634 proceed to consider_string_end without incrementing string
8635 position. Don't increment display vector index past the end of
8636 the display vector. (Bug#11417)
8637 (pos_visible_p): Don't report a position visible when move_it_to
8638 stopped at the last line of window, which happens to be scanned
8639 backwards by the bidi iteration. (Bug#11464)
8641 2012-05-14 Eli Zaretskii <eliz@gnu.org>
8643 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
8644 and right-margin display specs even if the spec is invalid or we
8645 are on a TTY, and thus unable to display on the fringes.
8646 That's because the text with the property will not be displayed anyway,
8647 so we need to signal to the caller that this is a "replacing"
8648 display spec. This fixes display when the spec is invalid or we
8651 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
8653 * unexaix.c (make_hdr): Fix typo in prototype.
8654 This bug broke the build on AIX. Problem reported by Gilles Pion.
8656 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
8658 * keyboard.c (kbd_buffer_get_event): Read special events also in
8659 batch mode. (Bug#11415)
8661 2012-05-12 Glenn Morris <rgm@gnu.org>
8663 * ns.mk: Update for ns_appbindir no longer having trailing "/".
8665 2012-05-12 Eli Zaretskii <eliz@gnu.org>
8667 * lisp.mk (lisp): Add newcomment.elc.
8669 2012-05-12 Glenn Morris <rgm@gnu.org>
8671 * Makefile.in (MKDIR_P): New, set by configure.
8672 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
8674 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
8676 Remove unused function hourglass_started.
8677 * dispextern.h (hourglass_started):
8678 * w32fns.c (hourglass_started):
8679 * xdisp.c (hourglass_started): Remove.
8681 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
8683 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
8684 Update dependencies.
8686 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
8688 * xgselect.c (xg_select): Put maxfds+1 into a var.
8689 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
8691 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
8693 2012-05-10 Dave Abrahams <dave@boostpro.com>
8695 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
8696 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
8698 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
8700 * dbusbind.c (xd_registered_buses): New internal Lisp object.
8701 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
8702 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
8703 Initialize xd_registered_buses.
8705 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
8707 Untag more efficiently if USE_LSB_TAG.
8708 This is based on a proposal by YAMAMOTO Mitsuharu in
8709 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
8710 For an admittedly artificial (nth 8000 longlist) benchmark on
8711 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
8712 Emacs's overall text size by 1%.
8713 * lisp.h (XUNTAG): New macro.
8714 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
8715 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
8716 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
8717 * eval.c (Fautoload):
8718 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
8719 * frame.h (XFRAME): Use XUNTAG.
8721 Port recent dbusbind.c changes to 32-bit --with-wide-int.
8722 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
8723 Remove unportable assumptions about print widths of types like
8725 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
8726 intptr_t when converting between pointer and integer, to avoid GCC
8727 warnings about wrong width.
8729 2012-05-09 Eli Zaretskii <eliz@gnu.org>
8731 * w32proc.c (new_child): Force Windows to reserve only 64KB of
8732 stack for each reader_thread, instead of defaulting to 8MB
8733 determined by the linker. This avoids failures in creating
8734 subprocesses on Windows 7, see the discussion in this thread:
8735 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
8737 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
8739 Fix up display of the *Minibuf-0* buffer in the mini window.
8740 * keyboard.c (read_char): Don't clear the echo area if there's no
8742 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
8743 contents of *Minibuf-0*) if there's no message displayed in its stead.
8745 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
8747 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
8750 2012-05-06 Chong Yidong <cyd@gnu.org>
8752 * lisp.mk (lisp): Update.
8754 2012-05-05 Jim Meyering <meyering@redhat.com>
8756 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
8758 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
8760 * data.c (PUT_ERROR): New macro.
8761 (syms_of_data): Use it. Add new error type `user-error'.
8762 * undo.c (user_error): New function.
8763 (Fprimitive_undo): Use it.
8764 * print.c (print_error_message): Adjust print style for `user-error'.
8765 * keyboard.c (user_error): New function.
8766 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
8768 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
8770 Do not limit current-time-string to years 1000..9999.
8771 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
8772 (Fcurrent_time_string): Support any year that is supported by the
8773 underlying localtime representation. Don't use asctime, as it
8774 has undefined behavior for years outside the range -999..9999.
8776 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
8778 Fix race conditions involving setenv, gmtime, localtime, asctime.
8779 Without this fix, interrupts could mess up code that uses these
8780 nonreentrant functions, since setting TZ invalidates existing
8781 tm_zone or tzname values, and since most of these functions return
8782 pointers to static storage.
8783 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
8784 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
8785 Grow the critical sections to include not just invoking
8786 localtime/gmtime, but also accessing these functions' results
8787 including their tm_zone values if any, and any related TZ setting.
8788 (format_time_string): Last arg is now struct tm *, not struct tm **,
8789 so that the struct tm is saved in the critical section.
8790 All callers changed. Simplify allocation of initial buffer, partly
8791 motivated by the fact that memory allocation needs to be outside
8792 the critical section.
8794 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
8796 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
8797 with RESET_INTERVAL.
8799 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
8800 Remove duplicated buffer name initialization.
8802 2012-05-02 Jim Meyering <jim@meyering.net>
8804 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
8806 * xfns.c (x_window): Use xstrdup (Bug#11375).
8808 2012-05-02 Eli Zaretskii <eliz@gnu.org>
8810 * xdisp.c (pos_visible_p): If already at a newline from the
8811 display string before the 'while' loop, don't walk back the glyphs
8812 from it3.glyph_row. Solves assertion violation when the display
8813 string begins with a newline (egg.el). (Bug#11367)
8815 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
8817 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
8820 2012-05-01 Glenn Morris <rgm@gnu.org>
8822 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
8823 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
8824 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
8825 All were removed before 23.1.
8827 * dispnew.c: Remove HAVE_LIBNCURSES test;
8828 it is always true on relevant platforms.
8830 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
8831 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
8833 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
8835 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
8837 * .gdbinit (xpr): Remove checks for no longer existing misc types.
8838 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
8841 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
8843 Do not avoid creating empty evaporating overlays (Bug#9642).
8844 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
8845 That is, do not delete an evaporating overlay if it becomes
8846 empty after its bounds are adjusted to fit within its buffer.
8847 This fix caused other problems, and I'm reverting it until we get
8848 to the bottom of them.
8850 2012-04-27 Chong Yidong <cyd@gnu.org>
8852 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
8854 2012-04-27 Eli Zaretskii <eliz@gnu.org>
8856 * xdisp.c (pos_visible_p): If the window start position is beyond
8857 ZV, start the display from buffer beginning. Prevents assertion
8858 violation in init_iterator when the minibuffer window is scrolled
8861 * window.c (window_scroll_pixel_based): Likewise.
8863 2012-04-27 Chong Yidong <cyd@gnu.org>

8881 character. (Bug#11341)
8883 * w32menu.c: Include w32heap.h.
8884 (add_menu_item): If the call to AppendMenuW (via
8885 unicode_append_menu) fails, disable Unicode menus only if we are
8886 running on Windows 9X/Me.
8888 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
8890 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.

8909 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
8911 Do not create empty overlays with the evaporate property (Bug#9642).
8912 * buffer.c (Fmove_overlay): Delete an evaporating overlay
8913 if it becomes empty after its bounds are adjusted to fit within
8914 its buffer. Without this fix, in a nonempty buffer (let ((o
8915 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
8916 yields an empty overlay that has the evaporate property, which is
8917 not supposed to happen.
8919 Fix minor GTK3 problems found by static checking.
8920 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)

9057 (print_object): Check for cycles even when print-circle is nil and
9058 print-gensym is t, but only check print_depth if print-circle is nil.
9060 2012-04-20 Chong Yidong <cyd@gnu.org>
9062 * process.c (wait_reading_process_output): If EIO occurs on a pty,

9118 New extern decls, to avoid calling undeclared functions.
9119 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
9120 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
9121 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.

9143 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
9145 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

9166 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
9168 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

9191 2012-04-11 Daniel Colascione <dancol@dancol.org>
9193 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
9194 against is gone. It's better to use vfork now so that when Cygwin
9195 gains a new, working vfork, we use it automatically (bug#10398).
9197 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

9237 * gnutls.c (gnutls_log_function2i): Convenience log function.
9238 (emacs_gnutls_read): Use new log functions,
9239 `gnutls_handshakes_tried' process member, and

9252 2012-04-09 Eli Zaretskii <eliz@gnu.org>
9254 * xdisp.c (set_cursor_from_row): If the display string appears in
9255 the buffer at position that is closer to point than the position
9256 after the display string, display the cursor on the first glyph of
9257 the display string. Fixes cursor display when a 'display' text
9258 property immediately follows invisible text. (Bug#11094)
9260 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
9262 composite.c: use 'double' consistently
9263 * composite.c (get_composition_id): Use 'double' consistently
9264 instead of converting 'float' to 'double' and vice versa; this is
9265 easier to understand and avoids a GCC warning.
9267 2012-04-09 Glenn Morris <rgm@gnu.org>
9269 * Makefile.in: Generate leim-list with bootstrap-emacs, in
9270 preparation for dumping it with emacs. (Bug#4789)

9303 2012-04-07 Eli Zaretskii <eliz@gnu.org>
9305 Support building on MS-Windows with libxml2.
9307 * makefile.w32-in (OBJ2): Add xml.$(O).
9308 (GLOBAL_SOURCES): Add xml.c.
9309 ($(BLD)/xml.$(O)): New dependency list.
9311 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
9312 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
9313 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
9314 [!WINDOWSNT]: New macros.
9315 (init_libxml2_functions, libxml2_loaded_p): New functions.
9316 (parse_region): Call fn_xmlCheckVersion instead of using the macro
9317 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
9318 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
9319 Calls xmlCleanupParser only if libxml2 was loaded (or statically
9321 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
9322 Call init_libxml2_functions before calling libxml2 functions.
9323 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
9325 * emacs.c: Don't include libxml/parser.h.
9326 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
9327 xmlCleanupParser directly.
9329 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
9331 2012-04-07 Eli Zaretskii <eliz@gnu.org>
9333 * indent.c (Fvertical_motion): If there is a display string at
9334 point, use it.vpos to compute how many lines to backtrack after
9335 move_it_to point. (Bug#11133)
9337 2012-04-06 Eli Zaretskii <eliz@gnu.org>
9339 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
9340 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
9341 about subtle differences between FETCH_CHAR* and STRING_CHAR*
9342 macros related to unification of CJK characters. For the details,
9343 see the discussion following the message here:
9344 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
9346 2012-04-04 Chong Yidong <cyd@gnu.org>
9348 * keyboard.c (Vdelayed_warnings_list): Doc fix.
9350 2012-04-01 Eli Zaretskii <eliz@gnu.org>
9352 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
9353 instead of alloca. (Bug#11138)
9355 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
9357 * w32menu.c (is_simple_dialog): Properly check lisp types.
9360 2012-03-31 Eli Zaretskii <eliz@gnu.org>
9362 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
9363 position we get to after a call to move_it_to fails the
9364 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
9365 only if we wind up in a string from display property. (Bug#11063)
9367 * window.c (Fdelete_other_windows_internal): Invalidate the row
9368 and column information about mouse highlight, so that redisplay
9369 restores it after reallocating the glyph matrices. (Bug#7464)
9371 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
9372 string comes from a `display' text property, use the buffer
9373 position of that property as if we actually saw that position in
9375 (move_it_by_lines): Remove the assertion that
9376 "it->current_x == 0 && it->hpos == 0" which can be legitimately
9377 violated when there's a before-string at the beginning of a line.
9380 2012-03-30 Eli Zaretskii <eliz@gnu.org>
9382 * xdisp.c (append_space_for_newline): If the default face was
9383 remapped, use the remapped face for the appended newline.
9384 (extend_face_to_end_of_line): Use the remapped default face for
9385 extending the face to the end of the line.
9386 (display_line): Call extend_face_to_end_of_line when the default
9387 face was remapped. (Bug#11068)
9389 2012-03-29 Eli Zaretskii <eliz@gnu.org>
9391 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
9393 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
9395 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
9397 2012-03-27 Glenn Morris <rgm@gnu.org>
9399 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
9402 2012-03-26 Kenichi Handa <handa@m17n.org>
9404 * dispextern.h (struct glyph): Fix previous change. Change the
9405 bit length of glyphless.ch to 25 (Bug#11082).
9407 2012-03-26 Chong Yidong <cyd@gnu.org>
9409 * keyboard.c (Vselection_inhibit_update_commands): New variable.
9410 (command_loop_1): Use it; inhibit selection update for
9411 handle-select-window too (Bug#8996).
9413 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
9415 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
9417 2012-03-25 Kenichi Handa <handa@m17n.org>
9419 * dispextern.h (struct glyph): Change the bit length of
9420 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
9422 2012-03-24 Eli Zaretskii <eliz@gnu.org>
9424 * s/ms-w32.h (tzname): Include time.h before redirecting to
9425 _tzname. Fixes the MSVC build. (Bug#9960)
9427 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
9429 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
9432 * xterm.c (XTread_socket): Only modify handling_signal if
9433 !SYNC_INPUT. (Bug#11080)
9435 2012-03-23 Eli Zaretskii <eliz@gnu.org>
9437 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
9438 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
9439 when fetching a multibyte character consumes more bytes than
9440 CHAR_BYTES returns, due to unification of CJK characters in
9441 string_char. (Bug#11073)
9443 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
9445 * process.c (wait_reading_process_output): Handle pty disconnect
9446 by refraining from sending oneself a SIGCHLD (bug#10933).
9448 2012-03-22 Chong Yidong <cyd@gnu.org>
9450 * dispextern.h (struct it): New member string_from_prefix_prop_p.
9452 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
9453 Mark string as coming from a prefix property.
9454 (handle_face_prop): Use default face for prefix strings (Bug#4281).
9455 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
9457 2012-03-21 Chong Yidong <cyd@gnu.org>
9459 * xfaces.c (Vface_remapping_alist): Doc fix.
9461 2012-03-20 Eli Zaretskii <eliz@gnu.org>
9463 * w32proc.c (Fw32_set_console_codepage)
9464 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
9467 2012-03-20 Chong Yidong <cyd@gnu.org>
9469 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
9470 to reflect default non-nil value of redisplay-dont-pause.
9472 2012-03-19 Kenichi Handa <handa@m17n.org>
9474 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
9475 it fit in a valid range (Bug#11003).
9477 2012-03-18 Eli Zaretskii <eliz@gnu.org>
9479 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
9480 that is not from display property, accept the row as a "cursor
9481 row" if one of the string's character has a non-nil `cursor'
9482 property. Fixes cursor positioning when there are newlines in
9483 overlay strings, e.g. in icomplete.el. (Bug#11035)
9485 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
9487 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
9489 2012-03-12 Chong Yidong <cyd@gnu.org>
9491 * eval.c (inhibit_lisp_code): Rename from
9492 inhibit_window_configuration_change_hook; move from window.c.
9494 * xfns.c (unwind_create_frame_1, Fx_create_frame):
9495 * window.c (run_window_configuration_change_hook)
9496 (syms_of_window): Callers changed.
9498 2012-03-11 Chong Yidong <cyd@gnu.org>

9511 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
9513 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
9515 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
9516 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
9519 2012-03-03 Glenn Morris <rgm@gnu.org>
9521 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
9523 2012-03-02 Eli Zaretskii <eliz@gnu.org>
9525 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
9526 position past the first glyph_row that ends at ZV. (Bug#10902)
9527 (redisplay_window, next_element_from_string): Fix typos in
9529 (redisplay_window): Pass to move_it_vertically the margin in
9530 pixels, not in screen lines.
9532 2012-03-02 Glenn Morris <rgm@gnu.org>
9534 * buffer.c (buffer-list-update-hook): Doc fix.
9536 2012-02-29 Eli Zaretskii <eliz@gnu.org>
9538 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
9539 push_it before setting up the iterator for the first overlay
9540 string, even if we have an empty string loaded.
9541 (next_overlay_string): If there's an empty string on the iterator
9542 stack, pop the stack. (Bug#10903)
9544 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
9546 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
9547 Suggested by Stefan Monnier in
9548 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
9549 * alloc.c (widen_to_Lisp_Object): New static function.
9550 (mark_memory): Also mark Lisp_Objects by fetching pointer words
9551 and widening them to Lisp_Objects. This would work even if
9552 USE_LSB_TAG is defined and wide integers are used, which might
9553 happen in a future version of Emacs.
9555 2012-02-25 Chong Yidong <cyd@gnu.org>
9557 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
9560 * xselect.c (Fx_selection_exists_p): Doc fix.
9561 (x_clipboard_manager_save_all): Print an informative message
9562 before saving to clipboard manager.
9564 2012-02-24 Chong Yidong <cyd@gnu.org>
9566 * keyboard.c (process_special_events): Handle all X selection
9567 requests in kbd_buffer, not just the next one (Bug#8869).
9569 2012-02-23 Chong Yidong <cyd@gnu.org>
9571 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
9572 call when setting menu-bar-lines and tool-bar-lines parameters.
9573 (unwind_create_frame_1): New helper function.
9575 * window.c (inhibit_window_configuration_change_hook): New var.
9576 (run_window_configuration_change_hook): Obey it.
9577 (syms_of_window): Initialize it.
9579 2012-02-22 Chong Yidong <cyd@gnu.org>
9581 * xterm.c (x_draw_image_relief): Add missing type check for
9582 Vtool_bar_button_margin (Bug#10743).
9584 2012-02-21 Chong Yidong <cyd@gnu.org>
9586 * fileio.c (Vfile_name_handler_alist): Doc fix.
9588 * buffer.c (Fget_file_buffer): Protect against invalid file
9589 handler return value.
9591 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
9593 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
9594 when computing $valmask.
9596 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
9597 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
9598 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
9599 It's useless in that case, and it can cause problems on hosts
9600 that allocate halves of EMACS_INT values separately.
9601 Reported by Dan Horák. Diagnosed by Andreas Schwab in
9602 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
9603 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
9604 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
9605 it avoids undefined behavior on hosts where shifting right by more
9606 than the word width has undefined behavior.
9608 2012-02-19 Chong Yidong <cyd@gnu.org>
9610 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
9611 (Funhandled_file_name_directory, Ffile_name_as_directory)
9612 (Fdirectory_file_name, Fexpand_file_name)
9613 (Fsubstitute_in_file_name): Protect against invalid file handler
9614 return values (Bug#10845).
9616 2012-02-18 Eli Zaretskii <eliz@gnu.org>
9618 * .gdbinit (pitx): Fix incorrect references to fields of the
9621 2012-02-17 Chong Yidong <cyd@gnu.org>
9623 * syntax.c (Fscan_lists): Doc fix (Bug#10833).
9625 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>
9627 * image.c (MAX_IMAGE_SIZE): Increase from 6.0 to 10.0; see
9628 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
9630 2012-02-15 Chong Yidong <cyd@gnu.org>
9632 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
9633 marked as special. Also, starting docstrings with * is obsolete.
9635 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
9637 * gnutls.c (emacs_gnutls_write): Fix last change.
9639 2012-02-13 Lars Ingebrigtsen <larsi@gnus.org>
9641 * gnutls.c (emacs_gnutls_write): Set errno appropriately for
9644 2012-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
9646 * keymap.c (Fsingle_key_description): Handle char ranges.
9648 2012-02-12 Chong Yidong <cyd@gnu.org>
9650 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
9651 as that creates a dangerous corner case.
9653 * window.c (Fdelete_window_internal): Invalidate the mouse
9654 highlight (Bug#9904).
9656 2012-02-12 Glenn Morris <rgm@gnu.org>
9658 * xselect.c (Fx_own_selection_internal)
9659 (Fx_get_selection_internal, Fx_disown_selection_internal)
9660 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
9661 * nsselect.m (Fx_own_selection_internal)
9662 (Fx_disown_selection_internal, Fx_selection_exists_p)
9663 (Fx_selection_owner_p, Fx_get_selection_internal):
9664 Sync docs and argument specs with the xselect.c versions.
9666 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>

9686 2012-02-07 Chong Yidong <cyd@gnu.org>
9688 * buffer.c (Fbuffer_local_variables)
9689 (buffer_lisp_local_variables): Handle unbound vars correctly;
9690 don't let Qunbound leak into Lisp.
9692 2012-02-07 Glenn Morris <rgm@gnu.org>
9694 * image.c (Fimagemagick_types): Doc fix.
9696 * image.c (imagemagick-render-type): Change it from a lisp object
9697 to an integer. Move the doc here from the lisp manual.

9702 * doc.c (store_function_docstring): Avoid applying docstring of
9703 alias to base function (Bug#2603).
9705 2012-02-04 Andreas Schwab <schwab@linux-m68k.org>
9707 * .gdbinit (pp1, pv1): Remove redundant defines.
9710 2012-02-04 Chong Yidong <cyd@gnu.org>
9712 * nsterm.m: Declare a global (Bug#10694).
9714 2012-02-04 Eli Zaretskii <eliz@gnu.org>
9716 * w32.c (get_emacs_configuration_options):
9717 Include --enable-checking, if specified, in the return value.
9719 2012-02-04 Martin Rudalics <rudalics@gmx.at>
9721 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
9722 after rounding frame sizes. (Bug#9723)

9726 * keyboard.c (adjust_point_for_property): Don't position point
9727 before BEGV. (Bug#10696)
9729 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
9731 Handle overflow when computing char display width (Bug#9496).
9732 * character.c (char_width): Return EMACS_INT, not int.
9733 (char_width, c_string_width): Check for overflow when
9734 computing the width; this is possible now that individual
9735 characters can have unbounded width. Problem introduced
9736 by merge from Emacs 23 on 2012-01-19.
9738 2012-02-02 Michael Albinus <michael.albinus@gmx.de>
9740 * dbusbind.c (Fdbus_register_method): Mention the return value

9753 2012-02-02 Kenichi Handa <handa@m17n.org>
9755 (x_produce_glyphs): Cancel previous change. If cmp->glyph_len is
9756 0, do not call append_composite_glyph.
9758 2012-02-02 Kenichi Handa <handa@m17n.org>
9760 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
9762 (x_produce_glyphs): If the component of a composition is a null
9763 string, set it->pixel_width to 1 to avoid zero-width glyph.
9765 2012-02-01 Eli Zaretskii <eliz@gnu.org>
9767 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
9768 first 2 arguments are identical. This makes inserting large
9769 output from a subprocess an order of magnitude faster on
9770 MS-Windows, where all sbrk'ed memory is always contiguous.
9772 2012-01-31 Glenn Morris <rgm@gnu.org>
9774 * nsterm.m (syms_of_nsterm) <x-toolkit-scroll-bars>:

9786 2012-01-28 Chong Yidong <cyd@gnu.org>
9788 * minibuf.c (syms_of_minibuf): Doc fix (Bug#10550).
9790 2012-01-26 Chong Yidong <cyd@gnu.org>

10300 * xdisp.c (redisplay_window): If cursor row is not fully visible
10301 after recentering, and scroll-conservatively is set to a large
10302 number, scroll window by a few more lines to make the cursor fully
10303 visible and out of scroll-margin. (Bug#10105)
10304 (start_display): Don't move to the next line if the display should
10305 start at a newline that is part of a display vector or an overlay
10306 string. (Bug#10119)

10385 Standardize on VIRT_ADDR_VARIES behavior (Bug#10042).
10386 Otherwise, valgrind does not work on some platforms.
10387 Problem reported by Andreas Schwab in
10388 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
10389 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
10390 is set, removing the need for VIRT_ADDRESS_VARIES.
10391 (PURE_P): Use a more-efficient implementation that needs just one
10392 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
10393 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
10394 to 4 (xorl, subq, cmpq, setbe).
10395 * alloc.c (pure): Always extern now, since that's the
10396 VIRT_ADDR_VARIES behavior.

10398 consistency with the new puresize.h.
10399 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
10400 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

10406 (erase_phys_cursor, update_window_cursor, show_mouse_face)
10407 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
10408 behave as if the cursor position were at the window margin.
10410 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
10411 and the cursor position is out of bounds, behave as if the cursor
10412 position were at the window margin. (Bug#10075)
10414 2011-11-18 Chong Yidong <cyd@gnu.org>
10416 * window.c (Fwindow_combination_limit): Make first argument

10435 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
10437 * xdisp.c (row_hash): New function, body extracted from
10438 compute_line_metrics.
10439 (compute_line_metrics): Call row_hash, instead of computing the
10442 * dispnew.c (verify_row_hash): Call row_hash for computing the
10443 hash code of a row, instead of duplicating code from xdisp.c.
10445 * dispextern.h (row_hash): Add prototype.
10447 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
10449 * frame.c (delete_frame): Don't delete the terminal when the last

10475 (Fsplit_window_internal, saved_window)
10476 (Fset_window_configuration, save_window_save): Rename all
10477 occurrences of window_nest to window_combination_limit.

10483 2011-11-14 Eli Zaretskii <eliz@gnu.org>
10485 * xdisp.c (display_line): Move the call to
10486 highlight_trailing_whitespace before the call to
10487 compute_line_metrics, since the latter needs to see the final
10488 faces of all the glyphs to compute ROW's hash value.
10489 Fixes assertion violations in row_equal_p. (Bug#10035)
10491 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
10493 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,
10494 just return (bug#10044).
10496 2011-11-12 Eli Zaretskii <eliz@gnu.org>
10498 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
10499 with user-defined heap size. Bump the default size of the temacs

10503 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
10504 current_matrix and desired_matrix. (Bug#9990)
10505 (verify_row_hash) [XASSERTS]: New function.
10506 (adjust_glyph_matrix, row_equal_p): Use it in xassert to verify
10507 that the hash value of glyph rows is correct.

10550 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
10552 Avoid some portability problems by eschewing 'extern inline' functions.
10553 The trivial performance wins aren't worth the portability hassles; see
10554 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
10556 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

10559 by removing the "extern"s.
10560 * intervals.c (adjust_intervals_for_insertion)
10561 (adjust_intervals_for_deletion): Undo previous change,
10562 making these static again.
10563 (offset_intervals, temp_set_point_both, temp_set_point)
10564 (copy_intervals_to_string): No longer inline.
10565 * xdisp.c (window_text_bottom_y, window_box_width)

10622 * xmenu.c (cleanup_widget_value_tree): New function.
10623 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
10624 calling free_menubar_widget_value_tree directly (Bug#9830).

10630 (window_box_width, window_box_left, window_box_left_offset)
10631 (window_box_right, window_box_right_offset): Declare extern.
10632 Otherwise, these inline functions do not conform to C99 and
10633 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
10634 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
10635 * intervals.c (adjust_intervals_for_insertion)

10638 (static_offset_intervals): Remove.
10639 (offset_intervals): Rewrite using the old contents of
10640 static_offset_intervals. The old version didn't conform to C99
10641 because an extern inline function contained a reference to an
10642 identifier with static linkage.

10694 * nsfns.m: Declare image_cache_refcount if GLYPH_DEBUG.
10695 (unwind_create_frame): New function (Bug#9943).
10696 (Fx_create_frame): Restructure code to be more similar to the one in
10697 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).

10740 (alloca) [_MSC_VER]: Define to _alloca.
10742 * lisp.h (DECL_ALIGN) [_MSC_VER]: Define for MSVC.
10744 * regex.c <re_char> [_MSC_VER]: A separate definition for MSVC.
10746 2011-11-04 Eli Zaretskii <eliz@gnu.org>
10748 * xdisp.c (note_mouse_highlight): If either of
10749 previous/next-single-property-change returns nil, treat that as
10750 the beginning or the end of the buffer. (Bug#9955)
10752 2011-11-04 Jan Djärv <jan.h.d@swipnet.se>
10754 * gtkutil.c (xg_make_tool_item): Add callbacks if one of wimage or
10755 label is not null (Bug#9951).
10756 (xg_tool_item_stale_p): Handle the fact that wimage and/or wlbl
10759 2011-11-04 Eli Zaretskii <eliz@gnu.org>
10761 * window.c (Fwindow_body_size): Mention in the doc string that the
10762 return value is in frame's canonical units. (Bug#9949)
10764 2011-11-03 Eli Zaretskii <eliz@gnu.org>
10766 * xdisp.c (note_mouse_highlight): Initialize `area'. (Bug#9947)
10768 * w32fns.c (unwind_create_frame): If needed, free the glyph
10769 matrices of the partially constructed frame. (Bug#9943)
10770 * xfns.c (unwind_create_frame): Likewise.
10772 2011-11-01 Eli Zaretskii <eliz@gnu.org>
10774 * xdisp.c (mouse_face_from_buffer_pos): Fix a typo in a comment.
10775 Don't stop backward scan on the continuation glyph, even though
10776 its CHARPOS is positive.
10777 (mouse_face_from_buffer_pos, note_mouse_highlight):
10778 Rename cover_string to disp_string.
10780 2011-11-01 Martin Rudalics <rudalics@gmx.at>
10782 * window.c (temp_output_buffer_show): Don't use
10783 Vtemp_buffer_show_specifiers.
10784 (Vtemp_buffer_show_specifiers): Remove unused variable.
10786 2011-10-30 Eli Zaretskii <eliz@gnu.org>
10788 * xdisp.c (try_cursor_movement): Make sure ROW isn't decremented
10789 past the beginning of the current glyph matrix.
10791 2011-10-30 Adam Sjøgren <asjo@koldfront.dk> (tiny change)
10793 * xterm.c: Include X11/Xproto.h if HAVE_GTK3.
10794 (x_error_handler): Ignore BadMatch for X_SetInputFocus for
10795 HAVE_GTK3 (Bug#9869).
10797 * gtkutil.c (xg_win_to_widget, xg_event_is_for_menubar): Initialize
10798 type to GDK_NOTHING so valgrind does not complain (Bug#9901).
10800 * xterm.h (x_display_info): Add Xatom_net_wm_state_hidden (Bug#9893).
10802 * xterm.c: Declare x_handle_net_wm_state to return int.
10803 (handle_one_xevent): Check if we are iconified but don't have
10804 _NET_WM_STATE_HIDDEN. If do, treat as deiconify (Bug#9893).
10805 (get_current_wm_state): Return non-zero if not hidden,
10806 check for _NET_WM_STATE_HIDDEN (Bug#9893).

10811 2011-10-29 Paul Eggert <eggert@cs.ucla.edu>
10813 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
10814 so that this new function doesn't get optimized away by a
10815 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
10817 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
10819 * frame.h (MOUSE_HL_INFO): Remove excess parens.
10821 2011-10-29 Eli Zaretskii <eliz@gnu.org>
10823 Fix the `xbytecode' command.
10824 * .gdbinit (xprintbytestr): New command.
10825 (xwhichsymbols): Rename from `which'; all callers changed.
10826 (xbytecode): Print the byte-code string as well.
10828 2011-10-29 Kim Storm <storm@cua.dk>
10830 * alloc.c (which_symbols): New function.
10832 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
10834 * minibuf.c (read_minibuf_noninteractive): Allow reading empty
10837 2011-10-29 Glenn Morris <rgm@gnu.org>
10839 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
10840 Not clear what it was for, and it causes various bugs. (Bug#9839)
10842 2011-10-28 Eli Zaretskii <eliz@gnu.org>
10844 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
10845 possible random value that matches one of those tested as
10846 condition to clear the mouse face.
10848 2011-10-28 Chong Yidong <cyd@gnu.org>
10850 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.
10852 2011-10-28 Dan Nicolaescu <dann@ics.uci.edu>
10854 * window.c (make_window): Initialize phys_cursor_on_p.
10856 2011-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
10858 * lisp.h (struct Lisp_Symbol): Update comments.
10860 2011-10-28 Juanma Barranquero <lekktu@gmail.com>
10862 * w32font.c (w32_load_unicows_or_gdi32): Add missing return.
10864 2011-10-28 Eli Zaretskii <eliz@gnu.org>
10866 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
10867 <oslsachem@gmail.com> for helping to debug this.
10869 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
10870 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
10871 (g_b_init_get_glyph_outline_w): New static variables.
10872 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
10873 (GetGlyphOutlineW_Proc): New typedefs.
10874 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
10875 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
10877 (w32font_open_internal, compute_metrics):
10878 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
10879 instead of calling the "wide" APIs directly.
10881 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
10883 * w32.h (syms_of_w32font): Add prototype.
10885 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
10887 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
10888 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
10889 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
10890 (Fmove_to_window_line): Doc fix.
10892 2011-10-27 Chong Yidong <cyd@gnu.org>
10894 * process.c (make_process): Set gnutls_state to NULL.
10896 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
10897 non-NULL, regardless of GNUTLS_INITSTAGE.
10898 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
10899 an error. Set process slots as soon as we allocate them.
10901 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
10903 2011-10-27 Chong Yidong <cyd@gnu.org>
10905 * gnutls.c (emacs_gnutls_deinit): New function.
10906 Deallocate credentials structures as well as calling gnutls_deinit.
10907 (Fgnutls_deinit, Fgnutls_boot): Use it.
10909 * process.c (make_process): Initialize GnuTLS credentials to NULL.
10910 (deactivate_process): Call emacs_gnutls_deinit.
10912 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
10914 * image.c (x_create_x_image_and_pixmap):
10915 * w32.c (sys_rename, w32_delayed_load):
10916 * w32font.c (fill_in_logfont):
10917 * w32reg.c (x_get_string_resource): Silence compiler warnings.
10919 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
10921 * w32fns.c (w32_default_color_map): New function,
10922 extracted from Fw32_default_color_map.
10923 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
10925 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
10927 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
10929 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
10931 * keyboard.c (test_undefined): New function (bug#9751).
10932 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
10934 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
10936 * sysdep.c (init_sys_modes): Fix the check for the controlling
10937 terminal (Bug#6649).
10939 2011-10-20 Eli Zaretskii <eliz@gnu.org>
10941 * dispextern.h (struct bidi_it): New member next_en_type.
10943 * bidi.c (bidi_line_init): Initialize the next_en_type member.
10944 (bidi_resolve_explicit_1): When next_en_pos is valid for the
10945 current character, check also for next_en_type being WEAK_EN.
10946 (bidi_resolve_weak): Don't enter the expensive loop if the current
10947 position is before next_en_pos. Record the bidi type of the first
10948 non-ET, non-BN character we find, in addition to its position.
10949 (bidi_level_of_next_char): Invalidate next_en_type when
10950 next_en_pos is over-stepped.
10952 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
10954 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
10955 * editfns.c: Rewrite current-time-zone so that it invokes
10956 the equivalent of (format-time-string "%Z") to get the time zone name.
10957 This fixes a bug when the time zone name contains characters that
10958 need converting from the system time locale to Emacs internal format.
10959 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
10960 that patch fixed format-time-string to do the conversion, but
10961 I forgot to fix current-time-zone.
10962 (format_time_string): New function, containing most of
10963 what Fformat_time_string used to contain.
10964 (Fformat_time_string): Rewrite in terms of format_time_string.
10965 This doesn't change this function's behavior.
10966 (current-time-zone): Rewrite to use format_time_string.
10967 This fixes the bug reported by Michael Schierl in
10968 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
10969 Jason Rumney's 2007-06-07 change worked around this bug, but
10971 * systime.h (tzname, timezone): Remove no-longer-used declarations.
10973 2011-10-19 Eli Zaretskii <eliz@gnu.org>
10975 * xdisp.c (start_display): If the character at POS is displayed
10976 via a display vector, reset IT->current.dpvec_index to zero.
10977 (try_window_reusing_current_matrix): If a line ends in a display
10978 vector or the next line starts in a display vector, continue
10979 redrawing the window even though the character position of
10980 start_row was reached.
10983 2011-10-18 Chong Yidong <cyd@gnu.org>
10985 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
10986 with nobreak-char-display too.
10988 2011-10-18 Eli Zaretskii <eliz@gnu.org>
10990 Fix part 3 of bug#9771.
10991 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
10992 (bidi_resolve_neutral): Don't enter the expensive loop looking for
10993 non-neutral characters if the current character is a paragraph
10994 separator (a.k.a. Newline). This avoids running the same
10995 expensive loop twice, once when we consume the preceding newline
10996 and the other time when the line actually needs to be displayed.
10997 Avoid the loop when we see neutrals on the base embedding level
10998 following a character whose directionality is the same as the
10999 paragraph's. This avoids running the expensive loop when a line
11000 ends in a long sequence of neutrals, like control characters.
11001 Add assertion against STRONG_AL type. Slightly rearrange code
11002 that determines the type of a neutral given the first non-neutral
11004 (bidi_level_of_next_char): Set next_en_pos to zero when
11005 invalidating its info.
11007 2011-10-17 Eli Zaretskii <eliz@gnu.org>
11009 * xdisp.c (push_display_prop): Determine whether to record string
11010 or buffer position by IT->string, not by IT->method. Allow
11011 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
11012 (move_it_vertically_backward): Don't look for character position
11013 immediately after the newline when in a continuation line.
11016 2011-10-15 Martin Rudalics <rudalics@gmx.at>
11018 * window.c (coordinates_in_window): Rewrite and delabelize
11019 vertical border check. (Bug#5357) (Bug#9618)
11021 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
11023 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
11024 errors in XSetWindowBorder (bug#9310).
11026 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
11028 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
11029 avoid crash when xmalloc overrun checking is enabled.
11031 2011-10-13 Eli Zaretskii <eliz@gnu.org>
11033 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
11034 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
11035 cursor motion with <left> and <right> arrow keys.
11037 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
11038 some callers set that themselves.
11040 2011-10-12 Eli Zaretskii <eliz@gnu.org>
11042 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
11043 display string and the previous row comes from the same string and
11044 is empty. (Bug#9739) (Bug#9738)
11046 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
11048 * doc.c (get_doc_string): Encode file name (bug#9735).
11050 2011-10-12 Eli Zaretskii <eliz@gnu.org>
11052 * bidi.c (bidi_level_of_next_char):
11053 * xdisp.c (get_visually_first_element): Remove old incorrect
11054 comments regarding the Unicode Line Separator character.
11056 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
11058 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
11060 * alloc.c (Fgc_status): Do not access beyond zombies array
11061 boundary if nzombies > MAX_ZOMBIES.
11062 * alloc.c (dump_zombies): Add missing format specifier.
11064 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
11066 * xdisp.c (set_cursor_from_row): Simplify conditionals,
11067 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
11069 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
11070 Some packages use them to denote characters with modifiers.
11072 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
11074 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
11075 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
11076 matching a pp-number. Rename parameter var to var1.
11078 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
11080 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
11082 2011-10-08 Glenn Morris <rgm@gnu.org>
11084 * callint.c (Fcall_interactively): Give a more explicit error for the
11085 'c' case with a non-character input. (Bug#8479)
11087 2011-10-08 Eli Zaretskii <eliz@gnu.org>
11089 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
11091 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
11092 lines that are hscrolled on the left.
11094 * dispnew.c (buffer_posn_from_coords): Account for a possible
11095 presence of header-line. (Bug#4426)
11097 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
11099 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
11100 Don't advertise functionality which we discourage or doesn't work.
11102 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
11104 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
11105 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
11106 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
11107 this makes Emacs dump core during garbage collection on rare
11108 occasions. sizeof is obviously inferior to offsetof here, so
11109 stick with offsetof.
11110 (GC_POINTER_ALIGNMENT): New macro.
11111 (mark_memory): Omit 3rd (offset) arg; caller changed.
11112 Don't assume EMACS_INT alignment is the same as pointer alignment.
11114 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
11116 * keyboard.c (read_key_sequence_remapped): New var.
11117 (read_key_sequence): Compute remapping in the right buffer.
11118 (command_loop_1): Use read_key_sequence's remapping directly.
11120 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
11122 * dired.c (file_name_completion): Don't expand file name.
11123 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
11124 before checking file name handler.
11126 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
11127 they've been requested explicitly (bug#9591).
11129 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
11131 * keymap.c (Fsingle_key_description): Use make_specified_string
11132 instead of build_string to build string from push_key_description.
11135 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
11137 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
11138 This fixes a Y2038 bug on 64-bit hosts.
11139 * buffer.c (reset_buffer):
11140 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
11141 (Fclear_buffer_auto_save_failure):
11142 Use 0, not -1, to represent an unset failure time, since time_t
11143 might not be signed.
11145 Remove dependency on glibc malloc internals.
11146 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11147 Move back here from lisp.h, but with their new implementations.
11148 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
11149 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
11150 * charset.c (charset_table_init): New static var.
11151 (syms_of_charset): Use it instead of xmalloc. This removes a
11152 dependency on glibc malloc internals. See Eli Zaretskii's comment in
11153 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
11154 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11155 Move back to alloc.c.
11156 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
11157 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
11159 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
11161 * nsterm.m (windowDidResize): Call x_set_window_size only when
11162 ns_in_resize is true. Otherwise set pixelwidth/height and
11163 call change_frame_size (Bug#9628).
11165 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
11167 Port --enable-checking=all to Fedora 14 x86-64.
11168 * charset.c (syms_of_charset): Also account for glibc malloc's
11169 internal overhead when calculating the initial malloc maximum.
11171 Port --enable-checking=all to Fedora 14 x86.
11172 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11174 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
11175 (overrun_check_realloc, overrun_check_free):
11176 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
11177 That way, xmalloc returns a properly-aligned pointer even if
11178 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
11179 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
11180 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
11181 into account when calculating the initial malloc maximum.
11182 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11183 Move here from alloc.c, so that charset.c can use it too.
11184 Properly align; the old code wasn't right for common 32-bit hosts
11185 when configured with --enable-checking=all.
11186 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
11187 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
11189 2011-09-29 Eli Zaretskii <eliz@gnu.org>

11196 * xdisp.c (compute_display_string_end): If there's no display
11197 string at CHARPOS, return -1.
11199 * bidi.c (bidi_fetch_char): When compute_display_string_end
11200 returns a negative value, treat the character as a normal
11201 character not covered by a display string. (Bug#9624)
11203 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
11205 * lread.c (Fread_from_string): Fix typo in docstring.
11207 2011-09-27 Eli Zaretskii <eliz@gnu.org>
11209 * xdisp.c (handle_invisible_prop): If invisible text ends on a
11210 newline, reseat the iterator instead of bidi-iterating there one
11211 character at a time. (Bug#9610)
11212 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
11213 TO_CHARPOS if the bidi iterator is at base embedding level.
11215 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
11217 * lread.c (readevalloop): Use correct code for NBSP.
11218 (read1): Likewise. (Bug#9608)
11220 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
11222 * dbusbind.c (Fdbus_register_signal): When service is not

11225 2011-09-25 Glenn Morris <rgm@gnu.org>
11227 * buffer.c (truncate-lines): Doc fix.
11229 2011-09-24 Chong Yidong <cyd@stupidchicken.com>

11247 Default value is now t. Doc fix.
11249 * indent.c (Fvertical_motion): Compute and apply the overshoot
11250 logic when moving up, not only when moving down. Fix the
11251 confusing name and values of the it_overshoot_expected variable;
11252 logic changes accordingly. (Bug#9254) (Bug#9549)
11254 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
11255 CHARPOS is covered by a display string which includes newlines.
11256 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
11257 is covered by a display string with embedded newlines.
11259 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
11261 * dbusbind.c (Fdbus_register_signal): Add match rule to
11262 Vdbus_registered_objects_table. (Bug#9581)
11263 (Fdbus_register_method, Vdbus_registered_objects_table):
11266 2011-09-24 Jim Meyering <meyering@redhat.com>
11268 do not ignore write error for any output size
11269 The previous change was incomplete.
11270 While it makes emacs --batch detect the vast majority of stdout
11271 write failures, errors were still ignored whenever the output size is
11272 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
11273 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
11274 && echo FAIL: ignored write error
11275 FAIL: ignored write error
11276 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
11277 && echo FAIL: ignored write error
11278 FAIL: ignored write error
11279 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
11281 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
11283 * emacs.c (Fkill_emacs): In noninteractive mode exit
11284 non-successfully if a write error occurred on stdout. (Bug#9574)
11286 2011-09-21 Eli Zaretskii <eliz@gnu.org>
11288 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
11291 * dispextern.h (struct it): Update the comment documenting what
11294 2011-09-20 Eli Zaretskii <eliz@gnu.org>
11296 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
11297 a display string, extend search for cursor position to end of row.
11298 (find_row_edges): If the row ends in a newline from a display
11299 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
11300 Handle the case of a display string with multiple newlines.
11301 (Fcurrent_bidi_paragraph_direction): Fix search for previous
11302 non-empty line. Fixes confusing cursor motion with arrow keys at
11303 the beginning of a line that starts with whitespace.
11305 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
11307 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
11310 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
11312 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
11313 boolean (Bug#9154).
11315 2011-09-18 Eli Zaretskii <eliz@gnu.org>
11317 * xdisp.c (display_line): Record maximum and minimum buffer
11318 positions even if no glyphs were produced (e.g., by a zero-width
11319 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
11320 buffer positions that will be removed from the glyph row because
11322 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
11323 column is beyond frame width: don't subtract 1 "pixel" when
11324 computing width of the stretch.
11325 (reseat_at_next_visible_line_start): Undo the change made on
11326 2011-09-17 that saved paragraph information and restored it after
11327 the call to `reseat'. (Bug#9545)
11329 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11331 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
11332 and turn window cursor on if cleared (Bug#9415).
11334 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
11336 * search.c (boyer_moore): Take unibyte characters from pattern
11337 literally. (Bug#9458)

11347 initialized, to pacify gcc -Wuninitialized.
11349 * fileio.c: Report proper errno when syscall falls.
11350 (Finsert_file_contents): Save and restore errno,
11351 so that report_file_error outputs the correct diagnostic.
11352 (Fwrite_region) [CLASH_DETECTION]: Likewise.
11354 2011-09-18 Eli Zaretskii <eliz@gnu.org>
11356 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
11358 2011-09-17 Eli Zaretskii <eliz@gnu.org>
11360 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
11361 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
11363 2011-09-17 Eli Zaretskii <eliz@gnu.org>
11365 * xdisp.c (reseat_at_next_visible_line_start): Keep information
11366 about the current paragraph and restore it after the call to reseat.
11368 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
11369 (bidi_find_paragraph_start): Search back for paragraph beginning
11370 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
11371 (bidi_move_to_visually_next): Only trigger paragraph-related
11372 computations when the last character is a newline or at EOB, not
11373 just any NEUTRAL_B. (Bug#9470)
11375 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
11376 truncated lines if point is covered by a display string. (Bug#9524)
11378 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
11380 * xselect.c: Relax test for outgoing X longs (Bug#9498).
11381 (cons_to_x_long): New function.
11382 (lisp_data_to_selection_data): Use it. Correct the test for
11383 short-versus-long data; it was negated. Break out of vector
11384 loop, for efficiency, when a long datum is discovered.
11386 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
11388 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
11390 2011-09-16 Eli Zaretskii <eliz@gnu.org>
11392 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
11393 GCC PR/17406) by declaring this function with external scope.
11395 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
11397 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
11398 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
11400 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
11402 * editfns.c (Fformat): Correctly handle text properties on "%%".

11412 of TAB characters in a composition.
11414 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
11416 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
11417 This occurs when processing a multibyte format.
11418 Problem reported by Wolfgang Jenker.
11420 2011-09-15 Johan Bockgård <bojohan@gnu.org>
11422 * xdisp.c (try_cursor_movement): Only check for exact match if
11423 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
11425 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
11427 Remove unused external symbols.
11428 * dispextern.h (calc_pixel_width_or_height): Remove decl.
11429 * xdisp.c (calc_pixel_width_or_height): Now static.
11430 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
11431 * indent.c (check_display_width):
11432 * w32term.c: Fix comment to match code.
11433 * xterm.c, xterm.h (x_catching_errors): Remove.
11435 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
11437 * xselect.c: Use signed conversions more consistently (Bug#9498).
11438 (selection_data_to_lisp_data): Assume incoming selection data are
11439 signed integers, not unsigned. This is to be consistent with
11440 outgoing selection data, which was modified to use signed integers
11441 in as part of the fix to Bug#9196 in response to Jan D.'s comment
11442 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
11443 expects long, not unsigned long.
11445 2011-09-14 Eli Zaretskii <eliz@gnu.org>
11447 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
11448 computation of loop end. Reported by Johan Bockgård
11451 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
11453 * frame.c (Fother_visible_frames_p): Function deleted.
11455 2011-09-12 Eli Zaretskii <eliz@gnu.org>
11457 * indent.c (compute_motion): Process display vector front to back
11458 rather than the other way around. (Bug#2496)
11460 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
11462 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
11464 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
11466 * minibuf.c (Fread_from_minibuffer): Doc fix.
11468 2011-09-11 Eli Zaretskii <eliz@gnu.org>
11470 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
11471 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
11473 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
11475 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
11476 value for non-existent files.
11478 2011-09-11 Eli Zaretskii <eliz@gnu.org>
11480 * fileio.c (Finsert_file_contents): If the file cannot be opened,
11481 set its "size" to -1. This will set the modtime_size field of
11482 the corresponding buffer to -1, which is what
11483 verify-visited-file-modtime expects for files that do not exist.
11486 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
11488 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
11490 * lisp.h: ... from here. push_key_description is no longer
11491 defined in keyboard.c, so its declaration should not be in
11492 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
11493 logically belongs with push_key_description.
11495 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
11497 * buffer.h: Include <sys/types.h> instead of <time.h>.
11498 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
11499 Problem reported by Herbert J. Skuhra.
11501 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
11503 * xml.c (parse_region): Make the parsing work for
11504 non-comment-starting XML files again (bug#9144).
11506 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
11508 * image.c (gif_load): Fix calculation of bottom and right corner.
11511 2011-09-10 Eli Zaretskii <eliz@gnu.org>
11513 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
11514 redisplay in small windows.
11516 2011-09-09 Eli Zaretskii <eliz@gnu.org>
11518 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
11520 2011-09-08 Martin Rudalics <rudalics@gmx.at>
11522 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
11523 Operate on live windows only.
11525 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
11527 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
11529 2011-09-07 Eli Zaretskii <eliz@gnu.org>
11531 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
11532 only under bidi iteration.
11534 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
11536 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
11538 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
11540 isnan: Fix porting problem to Solaris 10 with bundled gcc.
11541 Without this fix, the command to link temacs failed due to an
11542 undefined symbol __builtin_isnan. This is because
11543 /usr/include/iso/math_c99.h #defines isnan(x) to
11544 __builtin_isnan(x), but the bundled gcc, which identifies itself
11545 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
11547 * floatfns.c (isnan): #undef, and then #define to a clone of
11549 (Fisnan): Always define, since it's always available now.
11550 (syms_of_floatfns): Always define isnan at the Lisp level.
11552 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
11554 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
11556 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
11558 * fileio.c: Fix bugs with large file offsets (Bug#9428).
11559 The previous code assumed that file offsets (off_t values) fit in
11560 EMACS_INT variables, which is not true on typical 32-bit hosts.
11561 The code messed up by falsely reporting buffer overflow in cases
11562 such as (insert-file-contents "big" nil 1 2) into an empty buffer
11563 when "big" contains more than 2**29 bytes, even though this
11564 inserts just one byte and does not overflow the buffer.
11565 (Finsert_file_contents): Store file offsets as off_t
11566 values, not as EMACS_INT values. Check for overflow when
11567 converting between EMACS_INT and off_t. When checking for
11568 buffer overflow or for overlap, take the offsets into account.
11569 Don't use EMACS_INT for small values where int suffices.
11570 When checking for overlap, fix a typo: ZV was used where
11571 ZV_BYTE was intended.
11572 (Fwrite_region): Don't assume off_t fits into 'long'.
11573 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
11575 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
11577 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
11579 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
11581 sprintf-related integer and memory overflow issues (Bug#9412).
11583 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
11584 (esprintf, exprintf, evxprintf): New functions.
11585 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
11586 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
11587 (modify_event_symbol): Do not assume that the length of
11588 name_alist_or_stem is safe to alloca and fits in int.
11589 (Fexecute_extended_command): Likewise for function name and binding.
11590 (Frecursion_depth): Wrap around reliably on integer overflow.
11591 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
11592 since some callers pass EMACS_INT values.
11593 (Fsingle_key_description): Don't crash if symbol name contains more
11594 than MAX_ALLOCA bytes.
11595 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
11596 (get_minibuffer): Arg is now EMACS_INT, not int.
11597 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
11598 (esprintf, exprintf, evxprintf): New decls.
11599 * window.h (command_loop_level, minibuf_level): Reflect API changes.
11601 * dbusbind.c (signature_cat): New function.
11602 (xd_signature, Fdbus_register_signal):
11603 Do not overrun buffer; instead, report string overflow.
11605 * dispnew.c (add_window_display_history): Don't overrun buffer.
11606 Truncate instead; this is OK since it's just a log.
11608 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
11609 even if the time zone offset is outlandishly large.
11610 Don't mishandle offset == INT_MIN.
11612 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
11613 when creating daemon; the previous buffer-overflow check was incorrect.
11615 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
11616 which has the guts of the old verror function.
11618 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
11619 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
11621 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
11622 (font_unparse_xlfd): Don't blindly alloca long strings.
11623 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
11624 fits in int, when using sprintf. Use single snprintf to count
11625 length of string rather than counting it via multiple sprintfs;
11626 that's simpler and more reliable.
11627 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
11628 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
11629 sprintf, in case result does not fit in int.
11631 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
11632 (fontset_from_font): Print it.
11634 * frame.c (tty_frame_count): Now printmax_t, not int.
11635 (make_terminal_frame, set_term_frame_name): Print it.
11636 (x_report_frame_params): In X, window IDs are unsigned long,
11637 not signed long, so print them as unsigned.
11638 (validate_x_resource_name): Check for implausibly long names,
11639 and don't assume name length fits in 'int'.
11640 (x_get_resource_string): Don't blindly alloca invocation name;
11641 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
11644 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
11645 (xg_check_special_colors, xg_set_geometry):
11646 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
11648 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
11649 Use esprintf, not sprintf, in case result does not fit in int.
11651 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
11652 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
11653 it as a large positive number.

11655 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
11657 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
11658 in case result does not fit in int.
11660 * print.c (float_to_string): Detect width overflow more reliably.
11661 (print_object): Make sprintf buffer a bit bigger, to avoid potential
11662 buffer overrun. Don't assume list length fits in 'int'. Treat
11663 print length of 0 as 0, not as infinity; to be consistent with other
11664 uses of print length in this function. Don't overflow print length
11665 index. Don't assume hash table size fits in 'long', or that
11666 vectorlike size fits in 'unsigned long'.
11668 * process.c (make_process): Use printmax_t, not int, to format
11669 process-name gensyms.
11671 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
11673 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
11674 to avoid potential buffer overrun.
11676 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
11677 if X resource line is longer than 512 bytes.
11679 * xfns.c (x_window): Make sprintf buffer a bit bigger
11680 to avoid potential buffer overrun.
11682 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
11684 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
11686 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
11688 Integer overflow fixes for scrolling, etc.
11689 Without these, Emacs silently mishandles large integers sometimes.
11690 For example, "C-u 4294967297 M-x recenter" was treated as if
11691 it were "C-u 1 M-x recenter" on a typical 64-bit host.
11693 * xdisp.c (try_window_id): Check Emacs fixnum range before
11694 converting to 'int'.
11696 * window.c (window_scroll_line_based, Frecenter):
11697 Check that an Emacs fixnum is in range before assigning it to 'int'.
11698 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
11699 values converted from Emacs fixnums.
11700 (Frecenter): Don't wrap around a line count if it is out of 'int'
11701 range; instead, treat it as an extreme value.
11702 (Fset_window_configuration, compare_window_configurations):
11703 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
11705 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
11706 that can exceed INT_MAX. Check that EMACS_INT value is in range
11707 before assigning it to the (possibly-narrower) index.
11708 (match_limit): Don't assume that a fixnum can fit in 'int'.
11710 * print.c (print_object): Use ptrdiff_t, not int, for index that can
11713 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
11714 (Fvertical_motion): Don't wrap around LINES values that don't fit
11715 in 'int'. Instead, treat them as extreme values. This is good
11716 enough for windows, which can't have more than INT_MAX lines anyway.
11718 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
11720 * Require libxml/parser.h to avoid compilation warning.
11722 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
11724 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
11725 since this reportedly can destroy thread storage.
11727 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
11729 * syntax.c (find_defun_start): Update all cache variables if
11730 exiting early (Bug#9401).
11732 2011-08-30 Eli Zaretskii <eliz@gnu.org>
11734 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
11736 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
11737 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
11738 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
11740 * term.c (tty_append_glyph): New function.
11741 (produce_stretch_glyph): Static function and its prototype deleted.
11743 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
11746 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
11748 * image.c (parse_image_spec): Check for nonnegative, not for positive,
11749 when checking :margin (Bug#9390).
11750 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
11751 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
11752 so that the name doesn't mislead. All uses changed.
11754 2011-08-28 Johan Bockgård <bojohan@gnu.org>
11756 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
11759 2011-08-27 Eli Zaretskii <eliz@gnu.org>
11761 * xdisp.c (move_it_to): Don't bail out early when reaching
11762 position beyond to_charpos, if we are scanning backwards.
11763 (move_it_vertically_backward): When DY == 0, make sure we get to
11764 the first character in the line after the newline.
11766 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
11768 * ccl.c: Improve and simplify overflow checking (Bug#9196).
11769 (ccl_driver): Do not generate an out-of-range pointer.
11770 (Fccl_execute_on_string): Remove unnecessary check for
11771 integer overflow, noted by Stefan Monnier in
11772 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
11773 Remove a FIXME that didn't need fixing.
11774 Simplify the newly-introduced buffer reallocation code.
11776 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
11778 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
11780 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
11782 Integer and memory overflow issues (Bug#9196).
11784 * doc.c (get_doc_string): Rework so that
11785 get_doc_string_buffer_size is the actual buffer size, rather than
11786 being 1 less than the actual buffer size; this makes xpalloc more
11789 * image.c (x_allocate_bitmap_record, cache_image):
11790 * xselect.c (Fx_register_dnd_atom):
11791 Simplify previous changes by using xpalloc.
11793 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
11794 since either will do and ptrdiff_t is convenient with xpalloc.
11796 * charset.c (charset_table_size)
11797 (struct charset_sort_data.priority): Now ptrdiff_t.
11798 (charset_compare): Don't overflow if priorities differ greatly.
11799 (Fsort_charsets): Don't assume list length fits in int.
11800 Check for size-calculation overflow when allocating sort data.
11801 (syms_of_charset): Allocate an initial charset table that is
11802 just under 64 KiB, to avoid problems with glibc malloc and mmap.
11804 * cmds.c (internal_self_insert): Check for size-calculation overflow.
11806 * composite.h (struct composition.glyph_len): Now int, not unsigned.
11807 The actual value is always <= INT_MAX, and leaving it unsigned made
11808 overflow checking harder.
11810 * dispextern.h (struct glyph_matrix.rows_allocated)
11811 (struct face_cache.size): Now ptrdiff_t, for convenience in use
11812 with xpalloc. The values are still always <= INT_MAX.
11814 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
11816 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
11817 (SAFE_NALLOCA): New macro.
11819 * region-cache.c (struct boundary.pos, find_cache_boundary)
11820 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
11821 (set_cache_region, invalidate_region_cache)
11822 (revalidate_region_cache, know_region_cache, region_cache_forward)
11823 (region_cache_backward, pp_cache):
11824 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
11825 so that ptrdiff_t * can be passed to xpalloc.
11826 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
11827 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
11828 (pp_cache): Don't assume cache_len fits in int.
11829 * region-cache.h: Adjust extern decls to match.
11831 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
11832 EMACS_INT, since either will do, for xpalloc.
11834 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
11835 (xnmalloc, xnrealloc, xpalloc): New functions.
11837 * bidi.c (bidi_shelve_header_size): New constant.
11838 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
11839 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
11841 * bidi.c (bidi_cache_shrink):
11842 * buffer.c (overlays_at, overlays_in, record_overlay_string)
11844 Don't update size of array until after memory allocation succeeds,
11845 because xmalloc/xrealloc may not return.
11846 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
11847 now that we have proper integer overflow checking.
11848 (record_overlay_string, overlay_strings): Catch overflows when
11849 calculating size of overlay_str_buf.
11851 * callproc.c (Fcall_process): Check for size overflow when
11852 calculating size of args2.
11853 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
11854 Normally we prefer signed values, but sticking with ptrdiff_t would
11855 require adding more-complicated checks.
11857 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
11858 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
11859 Redo buffer-overflow calculations to avoid integer overflow.
11860 Add a FIXME comment where memory seems to be over-allocated.
11862 * character.c (Fstring): Check for size-calculation overflow.
11864 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
11865 unnecessary integer overflow. Check for size overflow.
11866 (encode_coding_object): Don't update size until xmalloc succeeds.
11868 * composite.c (get_composition_id): Check for overflow in glyph
11869 length calculations.
11871 Integer and memory overflow fixes for display code.
11872 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
11873 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
11874 (scrolling_window): Check for overflow in size calculations.
11875 (line_draw_cost, realloc_glyph_pool, add_row_entry):
11876 Don't assume glyph table len fits in int.

11878 (row_table_size): Now ptrdiff_t, not int.
11879 (scrolling_window): Avoid overflow in size calculations.
11880 Don't update size until allocation succeeds.
11881 * fns.c (concat): Check for overflow in size calculations.
11882 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.

11886 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
11887 (get_doc_string): Check for size calculation overflow.
11888 Don't update size until allocation succeeds.
11889 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
11890 EMACS_INT, where ptrdiff_t will do.
11891 (Fsubstitute_command_keys): Check for string overflow.
11893 * editfns.c (set_time_zone_rule): Don't assume environment length
11895 (message_length): Now ptrdiff_t, not int.
11896 (Fmessage_box): Don't update size until allocation succeeds.
11897 Don't assume message length fits in int.
11898 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
11900 * emacs.c (main): Do not reallocate argv, since there is a null at
11901 the end that can be overwritten, and this way there's no need to
11902 worry about size-calculation overflow.
11903 (sort_args): Check for size-calculation overflow.
11905 * eval.c (init_eval_once, grow_specpdl): Don't update size until
11907 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
11909 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
11910 (x_set_scroll_bar_width, x_figure_window_size):
11911 Check for integer overflow.
11912 (x_set_alpha): Do not assume XINT fits in int.
11914 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
11915 This is for the members text_lines, text_cols, total_lines, total_cols,
11916 where the system imposes an 'int' limit.
11918 * fringe.c (Fdefine_fringe_bitmap):
11919 Don't update size until alloc works.
11921 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
11922 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
11924 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
11925 Check for size-calculation overflow.
11926 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
11927 do, as we prefer signed integers.
11928 (id_to_widget.max_size, id_to_widget.used)
11929 (xg_store_widget_in_map, xg_remove_widget_from_map)
11930 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
11931 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
11932 Use and return ptrdiff_t, not int.
11933 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
11934 * gtkutil.h: Change prototypes to match the above.
11936 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
11937 are duplicate now that they've been promoted to lisp.h.
11938 (x_allocate_bitmap_record, x_alloc_image_color)
11939 (make_image_cache, cache_image, xpm_load):
11940 Don't update size until alloc is done.
11941 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
11943 Check for size calculation overflow.
11944 (ct_colors_allocated_max): New constant.
11945 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid
11948 * keyboard.c (read_char, menu_bar_items, tool_bar_items)
11949 (read_char_x_menu_prompt, read_char_minibuf_menu_width)
11950 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
11951 Use ptrdiff_t, not int, to count maps.
11952 (read_char_minibuf_menu_prompt): Check for overflow in size
11953 calculations. Don't update size until allocation succeeds.
11954 Redo calculations to avoid overflow.
11955 * keyboard.h: Change prototypes to match the above.
11957 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
11959 (current_minor_maps): Check for size calculation overflow.
11960 * keymap.h: Change prototypes to match the above.
11962 * lread.c (read1, init_obarray): Don't update size until alloc done.
11964 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.
11965 (store_kbd_macro_char): Reorder multiplicands to avoid overflow.
11967 * nsterm.h (struct ns_color_table.size, struct ns_color_table.avail):
11968 Now ptrdiff_t, not int.
11969 * nsterm.m (ns_index_color): Use ptrdiff_t, not int, for table indexes.

11981 (Fset_match_data): Don't assume list lengths fit in 'int'.
11983 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
11984 for command line length. Do not attempt to address one before the
11985 beginning of an array, as that's not portable.
11987 * term.c (max_frame_lines): Remove; unused.
11988 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
11990 (encode_terminal_code, calculate_costs): Check for size
11991 calculation overflow.

11994 done. Redo calculations to avoid overflow.
11995 (calculate_costs): Don't bother calling xmalloc when xrealloc will do.
11997 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
11998 subtracting pointers.
11999 (gobble_line): Check for overflow more carefully. Don't update size
12002 * tparam.c (tparam1): Use ptrdiff_t, not int, for sizes.

12013 Use ptrdiff_t, not int, for sizes.
12014 (Finternal_make_lisp_face, cache_face):
12015 Check for size calculation overflow.
12016 (cache_face): Treat size calculation overflows as if they were
12017 memory exhaustion (the usual treatment), rather than aborting.
12019 * xfns.c (x_encode_text, x_set_name_internal)
12020 (Fx_change_window_property): Use ptrdiff_t, not int, to count
12021 sizes, since they can exceed INT_MAX in size. Check for size
12022 calculation overflow.
12024 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
12025 (xg_select): Check for size calculation overflow.
12026 Don't update size until alloc done.
12028 * xrdb.c (get_environ_db): Don't assume path length fits in int,
12029 as sprintf is limited to int lengths.
12031 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
12032 (X_LONG_MIN): New macros.
12033 Use them to make the following changes clearer.
12034 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
12035 This change doesn't affect the value now, but it may help remind
12036 future maintainers not to raise the value too much later.
12037 (SELECTION_QUANTUM): Remove, replacing with ...
12038 (selection_quantum): ... new function, which avoids overflow.
12040 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
12041 assumption that selection length fits in 'int'.
12042 (x_reply_selection_request, x_handle_selection_request)
12043 (x_get_window_property, receive_incremental_selection)
12044 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
12045 (lisp_data_to_selection_data, clean_local_selection_data):
12046 Use ptrdiff_t, not int, to record length of selection.
12047 (x_reply_selection_request, x_get_window_property)
12048 (receive_incremental_selection, x_property_data_to_lisp):
12049 Redo calculations to avoid overflow.
12050 (x_reply_selection_request): When sending hint, ceiling it at
12051 X_LONG_MAX rather than relying on wraparound overflow to send
12053 (x_get_window_property, receive_incremental_selection)
12054 (lisp_data_to_selection_data, x_property_data_to_lisp):
12055 Check for size-calculation overflow.
12056 (x_get_window_property, receive_incremental_selection)
12057 (lisp_data_to_selection_data, Fx_register_dnd_atom):
12058 Don't store size until memory allocation succeeds.
12059 (x_get_window_property): Plug memory leak on memory exhaustion.
12060 Don't double-block input; malloc is safe here. Don't assume 2**34
12061 - 4 fits in unsigned long. Add an xassert to check
12062 XGetWindowProperty overflow. Be more careful about overflow
12063 calculations, and distinguish size from memory overflow better.
12064 (receive_incremental_selection): When tracing, don't assume
12065 unsigned int is less than INT_MAX.
12066 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
12067 harmful) conversions of unsigned short to int.
12068 (lisp_data_to_selection_data): Don't assume that integers
12069 in the range -65535 through -1 fit in an X unsigned short.
12070 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
12071 result parameters unless successful. Rely on cons_to_unsigned
12072 to report problems with elements; the old code wasn't right anyway.
12073 (x_check_property_data): Check for int overflow; we cannot use
12074 a wider type due to X limits.
12075 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
12077 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.
12079 * xterm.c (x_color_cells, x_send_scrollbar_event, handle_one_xevent)
12080 (x_term_init): Check for size calculation overflow.
12081 (x_color_cells): Don't store size until memory allocation succeeds.
12082 (handle_one_xevent): Use ptrdiff_t, not int, for byte counts.
12083 Don't assume alloca size is less than MAX_ALLOCA.
12084 (x_term_init): Don't assume length fits in int (sprintf is limited
12087 Use ptrdiff_t for composition IDs.

12107 * lisp.h (hash_lookup, hash_put):
12108 * minibuf.c (Ftest_completion):
12109 Use ptrdiff_t for hash table indexes, not int (which is too
12110 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
12111 32-bit --with-wide-int hosts).
12113 * charset.c (Fdefine_charset_internal): Check for integer overflow.
12114 Add a FIXME comment about memory leaks.
12115 (syms_of_charset): Don't assume xmalloc returns.
12117 Don't assume that stated character widths fit in int.

12119 * character.h (CHAR_WIDTH):
12120 * indent.c (MULTIBYTE_BYTES_WIDTH):
12121 Use sanitize_char_width to avoid undefined and/or bad behavior
12122 with outlandish widths.
12123 * character.h (sanitize_tab_width): Rename from sanitize_width,
12124 now that we have two such functions. All uses changed.
12125 (sanitize_char_width): New inline function.
12127 Don't assume that tab-width fits in int.
12128 * character.h (sanitize_width): New inline function.
12129 (SANE_TAB_WIDTH): New macro.

12138 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
12139 Remove unreachable code.
12140 (read_hex, load_charset_map_from_file): Check for integer overflow.
12142 * xterm.c: Don't go over XClientMessageEvent limit.
12143 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
12144 (x_send_scroll_bar_event): Likewise. Check that the size does not
12145 exceed limits imposed by XClientMessageEvent, as well as the usual
12146 ptrdiff_t and size_t limits.
12148 * keyboard.c: Overflow, signedness and related fixes.
12149 (make_lispy_movement): Use same integer type in forward decl
12150 that is used in the definition.
12151 (read_key_sequence, keyremap_step):
12152 Change bufsize argument back to int, undoing my 2011-03-30 change.
12153 We prefer signed types, and int is wide enough here.
12154 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
12155 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
12156 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
12157 length, not size_t. Use ptrdiff_t for index, not int.
12158 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
12159 possibility of integer overflow.
12161 Overflow, signedness and related fixes for images.

12182 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
12183 (lookup_image): Remove unnecessary tests.
12184 (xbm_image_p): Locals are now of int, not EMACS_INT,
12185 since parse_image_check makes sure they fit into int.
12186 (png_load, gif_load, svg_load_image):
12187 Prefer int to unsigned where either will do.
12188 (tiff_handler): New function, combining the cores of the
12189 old tiff_error_handler and tiff_warning_handler.
12190 This function is rewritten to use vsnprintf and thereby avoid
12191 stack buffer overflows. It uses only the features of vsnprintf
12192 that are common to both POSIX and native Microsoft.
12193 (tiff_error_handler, tiff_warning_handler): Use it.
12194 (tiff_load, gif_load, imagemagick_load_image):
12195 Don't assume :index value fits in 'int'.
12196 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
12197 (imagemagick_load_image): Check that crop parameters fit into
12198 the integer types that MagickCropImage accepts. Don't assume
12199 Vimagemagick_render_type has a nonnegative value. Don't assume
12200 size_t fits in 'long'.
12201 (gs_load): Use printmax_t to print the widest integers possible.
12202 Check for integer overflow when computing image height and width.

12214 handle_single_display_spec, not just 1 or zero.
12215 (handle_single_display_spec): If the display spec is of the form
12216 `(space ...)', and specifies display in the text area, return 2
12218 (try_cursor_movement): Check for the need to scroll more
12219 accurately, and prefer exact match for point under bidi.
12220 Don't advance `row' beyond the last row of the window.
12222 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
12223 into disp_prop; all users changed.
12225 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
12226 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
12227 for the text covered by the display property.

12237 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
12238 buffers, return left-to-right.
12239 (set_cursor_from_row): Consider candidate row a win if its glyph
12240 represents a newline and point is on that newline. Fixes cursor
12241 positioning on the newline at EOL of R2L text within L2R
12242 paragraph, and vice versa.
12243 (try_cursor_movement): Check continued rows, in addition to
12244 continuation rows. Fixes unwarranted scroll when point enters a
12245 continued line of R2L text within an L2R paragraph, or vice versa.
12246 (cursor_row_p): Consider the case of point being equal to
12247 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
12248 from the end of a short line to the beginning of a continued line
12249 of R2L text within L2R paragraph.
12250 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
12251 composed characters.

12266 2011-08-22 Kenichi Handa <handa@m17n.org>
12268 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
12269 extra slot even if the purpose is char-code-property-table.
12271 2011-08-23 Eli Zaretskii <eliz@gnu.org>
12273 * xdisp.c (redisplay_window): When computing centering_position,
12274 account for the height of the header line. (Bug#8874)
12276 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
12277 instead of CHAR_TO_BYTE. Fixes a crash when a completion
12278 candidate is selected by the mouse, and that candidate has a
12279 composed character under the mouse.
12281 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
12282 coordinates reported by pos-visible-in-window-p for a composed
12283 character in column zero.
12285 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
12287 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
12289 2011-08-22 Eli Zaretskii <eliz@gnu.org>
12291 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
12292 consider it a hit if to_charpos is anywhere in the range of the
12293 composed buffer positions.
12295 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
12297 * image.c (gif_load): Don't assume that each subimage has the same
12298 dimensions as the base image. Handle disposal method that is
12299 "undefined" by the gif spec (Bug#9335).
12301 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
12303 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).
12304 (Fcondition_case): Document `debug' symbol in error handler.
12306 2011-08-19 Eli Zaretskii <eliz@gnu.org>
12308 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
12309 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
12310 from an Org mode buffer to a Speedbar frame.
12312 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
12313 a composition, take its buffer position from IT->cmp_it.charpos.
12314 Fixes cursor positioning at the beginning of a line that begins
12315 with a composed character.
12317 2011-08-18 Eli Zaretskii <eliz@gnu.org>
12319 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
12320 character bidirectional type, use STRONG_L instead. Fixes crashes
12321 in a buffer produced by `describe-categories'.
12323 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
12324 members before the level stack, so they would be saved and
12325 restored when copying iterator state. Fixes incorrect reordering
12326 around TABs covered by display properties.
12328 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
12330 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

12336 Remove unnecessary aborts (Bug#9081).
12338 2011-08-17 Eli Zaretskii <eliz@gnu.org>
12340 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
12341 has no `load' handler, try opening the file locally. (Bug#9311)
12343 2011-08-16 Ken Brown <kbrown@cornell.edu>
12345 * gmalloc.c: Expand comment.
12347 2011-08-16 Eli Zaretskii <eliz@gnu.org>
12349 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
12350 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.

12390 coordinates of the iterator when restoring from ppos_it.
12393 2011-08-14 Kenichi Handa <handa@m17n.org>
12395 * process.c (create_process): Call setup_process_coding_systems
12396 after the pid of the process is set to -1 (Bug#8162).
12398 2011-08-14 Eli Zaretskii <eliz@gnu.org>
12400 * xdisp.c (move_it_in_display_line_to): Don't invoke
12401 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
12402 ppos_it. Fixes vertical cursor motion when line beginning is
12403 covered by an image. (Bug#9296)
12405 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
12407 * nsterm.h (ns_run_ascript): Declare.

12411 (ns_run_ascript): New function.
12412 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
12413 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
12414 the event loop. Get status from as_status (Bug#7276).
12416 * nsterm.m (sendEvent): If event is NSApplicationDefined and
12417 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
12418 the event loop (Bug#7276).
12420 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>

12443 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
12444 (Fnetwork_interface_list): Allocate in increments of bytes instead
12445 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
12446 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
12448 (struct ifflag_def): notrailers is smart on OSX.
12449 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
12450 Get hardware address with getifaddrs if available.
12452 2011-08-12 Eli Zaretskii <eliz@gnu.org>
12454 * xdisp.c (iterate_out_of_display_property): xassert that
12455 IT->position is set to within IT->object's boundaries. Break from
12456 the loop as soon as EOB is reached; avoids infloops in redisplay
12457 when IT->position is set up wrongly due to some bug.
12458 Set IT->current to match the bidi iterator unconditionally.
12459 (push_display_prop): Allow GET_FROM_STRING as IT->method on
12460 entry. Force push_it to save on the stack the current
12461 buffer/string position, to be restored by pop_it. Fix flags in
12462 the iterator structure wrt the object coming from a display
12463 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
12464 properties. (Bug#9284)
12466 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
12468 * fontset.c (fontset_get_font_group): Add proper type checks.

12481 no-display-properties-and-no-overlays under bidi display.
12482 Set disp_pos in the bidi iterator to avoid searches for display
12483 properties and overlays.
12485 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
12487 * editfns.c (Fset_time_zone_rule): Document relationship with the
12490 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
12491 the font entity extracted from the cache (Bug#8109).
12493 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
12495 * composite.c (autocmp_chars): Don't reset point. That is done by
12496 restore_point_unwind (Bug#5984).
12498 2011-08-07 Juri Linkov <juri@jurta.org>
12500 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
12501 to show the arg `TIME' instead of `TIMEVAL'.
12503 2011-08-06 Eli Zaretskii <eliz@gnu.org>
12505 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
12506 display property strides EOL and includes a newline, as in
12507 longlines-mode. (Bug#9254)
12508 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
12509 word-wrap under bidirectional display. (Bug#9224)
12511 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
12512 is non-zero, even if the data buffer is NULL. Fixes a crash in
12513 vertical-motion with longlines-mode. (Bug#9254)
12515 2011-08-05 Eli Zaretskii <eliz@gnu.org>
12517 * bidi.c <bidi_cache_total_alloc>: Now static.
12518 (bidi_initialize): Initialize bidi_cache_total_alloc.
12520 * xdisp.c (display_line): Release buffer allocated for shelved bidi
12523 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
12524 amount allocated this far in `bidi_cache_total_alloc'.
12525 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
12526 non-zero, only free the data buffer without restoring the cache
12527 contents. All callers changed.
12529 * dispextern.h (bidi_unshelve_cache): Update prototype.
12531 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
12532 (move_it_in_display_line, move_it_to)
12533 (move_it_vertically_backward, move_it_by_lines): Replace the call
12534 to xfree to an equivalent call to bidi_unshelve_cache.
12535 (move_it_in_display_line_to): Fix logic of returning
12536 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)

12540 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
12541 came from a string character with a `cursor' property. (Bug#9229)
12543 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
12545 * Makefile.in (LIB_PTHREAD): New variable.
12546 (LIBES): Add LIB_PTHREAD (Bug#9216).
12548 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
12549 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
12551 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
12553 * regex.c (re_iswctype): Remove some redundant boolean conversions.
12555 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
12557 * xterm.c (x_find_topmost_parent): New function.
12558 (x_set_frame_alpha): Find topmost parent window with
12559 x_find_topmost_parent and set the property there also (bug#9181).
12560 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
12562 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
12564 * callproc.c (Fcall_process): Avoid vfork clobbering
12565 the local vars buffer, coding_systems, current_dir.
12567 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
12569 * keymap.c (Fmake_composed_keymap): Move to subr.el.
12571 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
12573 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
12574 so that it is not optimized away.
12576 * xdisp.c (compute_display_string_pos): Remove unused local.
12578 2011-08-02 Eli Zaretskii <eliz@gnu.org>
12580 Fix slow cursor motion and scrolling in large buffers with
12581 selective display, like Org Mode buffers. (Bug#9218)
12583 * dispextern.h (struct bidi_it): New member disp_prop_p.
12585 * xdisp.c: Remove one-slot cache of display string positions.
12586 (compute_display_string_pos): Accept an additional argument
12587 DISP_PROP_P; callers changed. Scan at most 5K characters forward
12588 for a display string or property. If found, set DISP_PROP_P
12591 * bidi.c (bidi_fetch_char): Accept an additional argument
12592 DISP_PROP_P, and pass it to compute_display_string_pos.
12593 Only handle text covered by a display string if DISP_PROP_P is returned
12594 non-zero. All callers of bidi_fetch_char changed.
12596 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
12598 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
12600 2010-12-03 Don March <don@ohspite.net>
12602 * keymap.c (Fdefine_key): Fix non-prefix key error message when
12603 last character M-[char] is translated to ESC [char] (bug#7541).
12605 2011-08-02 Kenichi Handa <handa@m17n.org>
12607 * lisp.h (uniprop_table): Extern it.
12609 * chartab.c (uniprop_table): Make it non-static.
12611 2011-08-01 Eli Zaretskii <eliz@gnu.org>
12613 * xdisp.c (forward_to_next_line_start): Accept additional argument
12614 BIDI_IT_PREV, and store into it the state of the bidi iterator had
12616 (reseat_at_next_visible_line_start): Use the bidi iterator state
12617 returned by forward_to_next_line_start to restore the state of
12618 it->bidi_it after backing up to previous newline. (Bug#9212)
12620 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
12622 * regex.c (re_comp): Protoize.
12623 (re_exec): Fix return type.
12624 (regexec): Fix type of `ret'. (Bug#9203)
12626 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
12628 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
12629 This is needed if max-image-size is a floating-point number.
12631 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
12633 * print.c (print_object): Print empty symbol as ##.
12635 * lread.c (read1): Read ## as empty symbol.
12637 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
12639 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
12640 setting frame foreground color (Bug#9175).
12641 (x_set_background_color): Likewise.
12643 * nsmenu.m (-setText): Size tooltip dimensions precisely to
12644 contents (Bug#9176).
12645 (EmacsTooltip -init): Remove bezels and add shadows to
12648 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
12649 or scroll bar (Bug#8470).
12651 * nsfont.m (nsfont_open): Remove assignment to voffset and
12652 unnecessary vars hshink, expand, hd, full_height, min_height.
12653 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
12655 * nsterm.h (nsfont_info): Remove voffset field.
12657 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
12659 Implement strike-through and overline on NextStep (Bug#8863).
12661 * nsfont.m (nsfont_open): Use underline position provided by font,
12662 instead of hard-coded value of 2.
12663 (nsfont_draw): Call ns_draw_text_decoration instead.
12665 * nsterm.h: Add declaration for ns_draw_text_decoration.
12667 * nsterm.m (ns_draw_text_decoration): New function for drawing
12668 underline, overline, and strike-through.
12669 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
12670 ns_draw_text_decoration. Change treatment of cursor drawing to
12671 accommodate underlining, etc.
12673 2011-07-28 Eli Zaretskii <eliz@gnu.org>
12675 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
12678 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
12680 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
12681 Without this fix, if a signal arrives just after memory fills up,
12682 'malloc' might be invoked reentrantly.
12684 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
12685 In other words, assume that every image size is allowed, on non-X
12686 hosts. This assumption is probably wrong, but it lets Emacs compile.
12688 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
12690 * regex.c (re_iswctype): Convert return values to boolean.
12692 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
12694 * xdisp.c (compute_display_string_pos): Don't use cached display
12695 string position if the buffer had its restriction changed.
12698 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
12700 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
12702 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
12704 Integer signedness and overflow and related fixes. (Bug#9079)
12706 * bidi.c: Integer size and overflow fixes.
12707 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
12708 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
12709 (bidi_cache_find_level_change, bidi_cache_ensure_space)
12710 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
12711 (bidi_find_other_level_edge):
12712 Use ptrdiff_t instead of EMACS_INT where either will do.
12713 This works better on 32-bit hosts configured --with-wide-int.
12714 (bidi_cache_ensure_space): Check for size-calculation overflow.
12715 Use % rather than repeated addition, for better worst-case speed.
12716 Don't set bidi_cache_size until after xrealloc returns, because it
12718 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
12719 (bidi_cache_ensure_space): Also check that the bidi cache size
12720 does not exceed that of the largest Lisp string or buffer. See Eli
12721 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
12723 * alloc.c (__malloc_size_t): Remove.
12724 All uses replaced by size_t. See Andreas Schwab's note
12725 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
12727 * image.c: Improve checking for integer overflow.
12728 (check_image_size): Assume that f is nonnull, since
12729 it is always nonnull in practice. This is one less thing to
12730 worry about when checking for integer overflow later.
12731 (x_check_image_size): New function, which checks for integer
12732 overflow issues inside X.
12733 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
12734 This removes the need for a memory_full check.
12735 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
12736 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
12737 (xbm_read_bitmap_data): Change locals back to 'int', since
12738 their values must fit in 'int'.
12739 (xpm_load_image, png_load, tiff_load):
12740 Invoke x_create_x_image_and_pixmap earlier,
12741 to avoid much needless work if the image is too large.
12742 (tiff_load): Treat overly large images as if
12743 x_create_x_image_and_pixmap failed, not as malloc failures.
12744 (gs_load): Use x_check_image_size.
12746 * gtkutil.c: Omit integer casts.
12747 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
12748 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
12750 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
12752 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
12753 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
12754 would wrongly return t on a 64-bit host.
12756 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
12757 The plain *_OVERFLOW macros run afoul of GCC bug 49705
12758 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
12759 and therefore cause GCC to emit a bogus diagnostic in some cases.
12761 * image.c: Integer signedness and overflow and related fixes.
12762 This is not an exhaustive set of fixes, but it's time to
12763 record what I've got.
12764 (lookup_pixel_color, check_image_size): Remove redundant decls.
12765 (check_image_size): Don't assume that arbitrary EMACS_INT values
12766 fit in 'int', or that arbitrary 'double' values fit in 'int'.
12767 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
12768 (tiff_load, imagemagick_load_image):
12769 Check for overflow in size calculations.
12770 (x_create_x_image_and_pixmap): Remove unnecessary test for
12771 xmalloc returning NULL; that can't happen.
12772 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
12773 (xpm_color_bucket): Use better integer hashing function.
12774 (xpm_cache_color): Don't possibly over-allocate memory.
12775 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
12776 (gif_memory_source):
12777 Use ptrdiff_t, not int or size_t, to record sizes.
12778 (png_load): Don't assume values greater than 2**31 fit in 'int'.
12779 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
12780 either works, as we prefer signed integers.
12781 (tiff_read_from_memory, tiff_write_from_memory):
12782 Return tsize_t, not size_t, since that's what the TIFF API wants.
12783 (tiff_read_from_memory): Don't fail simply because the read would
12784 go past EOF; instead, return a short read.
12785 (tiff_load): Omit no-longer-needed casts.
12786 (Fimagemagick_types): Don't assume size fits into 'int'.
12788 Improve hashing quality when configured --with-wide-int.
12789 * fns.c (hash_string): New function, taken from sxhash_string.
12790 Do not discard information about ASCII character case; this
12791 discarding is no longer needed.
12792 (sxhash-string): Use it. Change sig to match it. Caller changed.
12793 * lisp.h: Declare it.
12794 * lread.c (hash_string): Remove, since we now use fns.c's version.
12795 The fns.c version returns a wider integer if --with-wide-int is
12796 specified, so this should help the quality of the hashing a bit.
12798 * emacs.c: Integer overflow minor fix.
12799 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
12800 Define only if GNU_LINUX.
12801 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
12803 * dispnew.c: Integer signedness and overflow fixes.
12804 Remove unnecessary forward decls, that were a maintenance hassle.
12805 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
12807 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
12808 (scrolling_window): Use ptrdiff_t, not int, for byte count.
12809 (prepare_desired_row, line_draw_cost):
12810 Use int, not unsigned, where either works.
12811 (save_current_matrix, restore_current_matrix):
12812 Use ptrdiff_t, not size_t, where either works.
12813 (init_display): Check for overflow more accurately, and without
12814 relying on undefined behavior.
12816 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
12817 Remove, replacing with the new symbols in lisp.h. All uses changed.
12818 * fileio.c (make_temp_name):
12819 * filelock.c (lock_file_1, lock_file):
12820 * xdisp.c (message_dolog):
12821 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
12822 Use pMd etc. instead.
12823 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
12824 replacing the pWIDE etc. symbols removed from editfns.c.
12826 * keyboard.h (num_input_events): Now uintmax_t.
12827 This is (very slightly) less likely to mess up due to wraparound.
12830 * buffer.c: Integer signedness fixes.
12831 (alloc_buffer_text, enlarge_buffer_text):
12832 Use ptrdiff_t rather than size_t when either will do, as we prefer
12835 * alloc.c: Integer signedness and overflow fixes.
12836 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
12837 (__malloc_size_t): Default to size_t, not to int.
12838 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
12839 (Fgarbage_collect, mark_object_loop_halt, mark_object):
12840 Prefer ptrdiff_t to size_t when either would do, as we prefer
12842 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
12843 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
12844 Now const. Initialize with values that are in range even if char
12846 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
12847 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
12848 These functions do the right thing with sizes > 2**32.
12849 (check_depth): Now ptrdiff_t, not int.
12850 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
12851 Adjust to new way of storing sizes. Check for size overflow bugs
12853 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
12854 slightly wrong anyway, as it missed one instance of
12855 XMALLOC_OVERRUN_CHECK_OVERHEAD.
12856 (refill_memory_reserve): Omit needless cast to size_t.
12857 (mark_object_loop_halt): Mark as externally visible.
12859 * xselect.c: Integer signedness and overflow fixes.
12860 (Fx_register_dnd_atom, x_handle_dnd_message):
12861 Use ptrdiff_t, not size_t, since we prefer signed.
12862 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
12863 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
12864 x_dnd_atoms_size and x_dnd_atoms_length.
12866 * doprnt.c: Prefer signed to unsigned when either works.
12868 * doprnt.c (doprnt):
12870 * xdisp.c (vmessage):
12871 Use ptrdiff_t, not size_t, when using or implementing doprnt,
12872 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
12873 prefer signed arithmetic to avoid comparison confusion.
12874 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
12875 but is a bit tricky.
12877 Assume freestanding C89 headers, string.h, stdlib.h.
12878 * data.c, doprnt.c, floatfns.c, print.c:
12879 Include float.h unconditionally.
12880 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
12881 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
12882 * regex.c: Likewise for stddef.h, string.h.
12883 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
12884 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
12885 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
12886 (STDC_HEADERS): Remove obsolete defines.
12887 * sysdep.c: Include limits.h unconditionally.
12889 Assume support for memcmp, memcpy, memmove, memset.
12890 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
12891 * regex.c (memcmp, memcpy):
12892 Remove; we assume C89 now.
12894 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
12895 (__malloc_safe_bcopy): Remove; no longer needed.
12897 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
12898 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
12899 well either way, and we prefer signed to unsigned.
12901 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
12903 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
12904 closes the connection while we're reading (bug#9182).
12906 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
12908 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
12909 are specified (Bug#9168).
12911 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
12913 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
12914 Found by GCC static checking and --with-wide-int on a 32-bit host.
12916 2011-07-25 Eli Zaretskii <eliz@gnu.org>
12918 * xdisp.c (compute_display_string_pos): Fix logic of caching
12919 previous display string position. Initialize cached_prev_pos to
12920 -1. Fixes slow-down at the beginning of a buffer.
12922 2011-07-24 Eli Zaretskii <eliz@gnu.org>
12924 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
12925 for attrs[LFACE_FONTSET_INDEX].
12927 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
12929 * xml.c (parse_region): Remove unused local
12930 that was recently introduced.
12932 2011-07-23 Eli Zaretskii <eliz@gnu.org>
12934 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
12935 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
12937 * xdisp.c (move_it_in_display_line_to): Record the best matching
12938 position for TO_CHARPOS while scanning the line, and restore it on
12939 exit if none of the characters scanned was an exact match.
12940 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
12941 when exact match is impossible due to invisible text, and the
12942 lines are truncated.
12944 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
12946 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
12949 2011-07-22 Eli Zaretskii <eliz@gnu.org>
12951 Fix a significant slow-down of cursor motion with C-n, C-p,
12952 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
12953 auto-repeat under bidi redisplay in fontified buffers.
12954 * xdisp.c (compute_stop_pos_backwards): New function.
12955 (next_element_from_buffer): Call compute_stop_pos_backwards to
12956 find a suitable prev_stop when we find ourselves before
12958 (reseat): Don't look for prev_stop, as that could mean a very long
12960 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
12961 <cached_disp_overlay_modiff>: Cache for last found display string
12963 (compute_display_string_pos): Return the cached position if asked
12964 about the same buffer in the same area of character positions, and
12965 the buffer wasn't changed since the time the display string
12966 position was cached.
12968 2011-07-22 Eli Zaretskii <eliz@gnu.org>
12970 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
12971 is an integer, which is important for empty lines. (Bug#9149)
12973 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
12975 * frame.c (Fmodify_frame_parameters): In tty case, update the
12976 default face if necessary (Bug#4238).
12978 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
12980 * editfns.c (Fstring_to_char): No need to explain what a character
12981 is in the docstring (Bug#6576).
12983 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
12985 * xml.c (parse_region): Make sure we always return a tree.
12987 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
12989 * xml.c (parse_region): If a document contains only comments,
12992 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
12994 * xml.c (make_dom): Return comments, too.

12999 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
13000 and the surrounding thread.
13001 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
13002 rather than fgets, and retry after EINTR. Otherwise, 'emacs
13003 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
13005 * s/openbsd.h (BROKEN_SIGIO): Define.
13006 * unexelf.c (unexec) [__OpenBSD__]:
13007 Don't update the .mdebug section of the Alpha COFF symbol table.
13009 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
13011 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
13014 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
13016 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
13017 This fixes some race conditions on the permissions of any newly
13020 * alloc.c (valid_pointer_p): Use pipe, not open.
13021 This fixes some permissions issues when debugging.
13023 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
13024 If fchown fails to set both uid and gid, try to set just gid,
13025 as that is sometimes allowed. Adjust the file's mode to eliminate
13026 setuid or setgid bits that are inappropriate if fchown fails.
13028 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
13030 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ

13036 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
13038 * lread.c (read_integer): Unread even EOF character.
13039 (read1): Likewise. Properly record start position of symbol.

13042 symbol character follows.
13044 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
13046 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
13047 This works around a problem with the previous change to Fcopy_file.
13048 Recent glibc declares fchown with __attribute__((warn_unused_result)),
13049 and without this change, GCC might complain about discarding
13050 fchown's return value.
13052 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
13054 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
13056 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
13058 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
13060 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
13062 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
13063 it's used from the C level.
13065 * process.c: Use the same condition for POLL_FOR_INPUT in both
13066 keyboard.c and process.c (bug#1858).
13068 2011-07-09 Lawrence Mitchell <wence@gmx.li>
13070 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
13071 (Fgnutls_boot): Use it.
13073 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
13075 * doc.c (Fsubstitute_command_keys): Revert last change.
13077 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
13079 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
13080 quotes the next character, and doesn't affect other longer
13081 sequences (bug#8935).
13083 * lread.c (syms_of_lread): Clarify that is isn't only
13084 `eval-buffer' and `eval-defun' that's affected by
13085 `lexical-binding' (bug#8460).
13087 2011-07-15 Eli Zaretskii <eliz@gnu.org>
13089 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
13090 bidi redisplay when a line includes both an image and is truncated.
13092 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
13094 Fix minor problems found by static checking.
13095 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
13096 (elsz): Now a signed constant, not a size_t var. We prefer signed
13097 types to unsigned, to avoid integer comparison confusion. Without
13098 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
13099 "cannot optimize loop, the loop counter may overflow", a symptom
13101 * indent.c (Fvertical_motion): Mark locals as initialized.
13102 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
13104 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>

13130 (display_string): If we need to ignore text properties of
13131 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
13132 original value of -1 will not work with bidi.)
13133 (compute_display_string_pos): First arg is now struct
13134 `text_pos *'; all callers changed. Support display properties on
13136 (compute_display_string_end): Support display properties on Lisp
13138 (init_iterator, reseat_1, reseat_to_string): Initialize the
13139 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
13140 when iterating on a string not from display properties).
13141 (compute_display_string_pos, compute_display_string_end):
13142 Fix calculation of the object to scan. Fixes an error when using
13144 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
13145 base_level_stop; instead, set base_level_stop to BEGV.
13146 Fixes crashes in vertical-motion.
13147 (next_element_from_buffer): Improve commentary for when
13148 the iterator is before prev_stop.
13149 (init_iterator): Initialize bidi_p from the default value of
13150 bidi-display-reordering, not from buffer-local value. Use the
13151 buffer-local value only if initializing for buffer iteration.
13152 (handle_invisible_prop): Support invisible properties on strings
13153 that are being bidi-reordered.

13172 parts of next_element_from_buffer, next_element_from_string, and
13173 next_element_from_c_string.
13174 (tool_bar_lines_needed, redisplay_tool_bar)
13175 (display_menu_bar): Force left-to-right direction. Add a FIXME
13176 comment for making that be controlled by a user option.

13186 iterator for displaying display or overlay strings.
13187 (forward_to_next_line_start): Don't use the shortcut if
13189 (back_to_previous_visible_line_start): If handle_display_prop
13190 pushed the iterator stack, restore the internal state of the bidi
13191 iterator by calling bidi_pop_it same number of times.
13192 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
13193 and we are bidi-iterating, don't decrement the iterator position;
13194 instead, set the first_elt flag in the bidi iterator, to produce
13196 (reseat_1): Remove redundant setting of string_from_display_prop_p.
13197 (push_display_prop): xassert that we are iterating a buffer.
13198 (push_it, pop_it): Save and restore paragraph_embedding member.
13199 (handle_single_display_spec, next_overlay_string)
13200 (get_overlay_strings_1, reseat_1, reseat_to_string)
13201 (push_display_prop): Set up the `unibyte' member of bidi_it.string
13202 correctly. Don't assume unibyte strings are not bidi-reordered.
13203 (compute_display_string_pos)
13204 (compute_display_string_end): Fix handling the case of C string.

13210 popping after iteration over a string that came from a display
13211 property. Fix a typo in popping stretch info. Add an assertion
13212 for verifying that the iterator position is in sync with the bidi
13214 (handle_single_display_spec, get_overlay_strings_1)

13303 (bidi_push_it, bidi_pop_it): Add prototypes.
13304 (struct iterator_stack_entry): New members bidi_p,
13305 paragraph_embedding, and from_disp_prop_p.

13359 The old code sometimes used this field without initializing it.
13361 * alloc.c (gc_sweep): Don't read past end of array.
13362 In theory, the old code could also have corrupted Emacs internals,
13363 though it'd be very unlikely.

13626 (clone_per_buffer_values): Don't assume that

13628 This isn't true in general, and it's particularly not true
13629 if Emacs is configured with --with-wide-int.
13630 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
13631 New macros, used in the buffer.c change.

13667 Random fixes. E.g., (random) never returned negative values.
13668 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
13669 subseconds part to the entropy, as that's a bit more random.
13670 Prefer signed to unsigned, since the signedness doesn't matter and
13671 in general we prefer signed. When given a limit, use a
13672 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
13673 latter isn't right if USE_2_TAGS_FOR_INTS.
13674 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
13675 not 0..VALMASK. Don't discard "excess" bits that random () returns.

13687 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
13688 This is more efficient than Ffile_directory_p and avoids a minor race.
13690 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
13692 * buffer.c (Foverlay_put): Say what the return value is
13695 * fileio.c (barf_or_query_if_file_exists): Check first if the file
13696 is a directory before asking whether to use the file name
13698 (barf_or_query_if_file_exists): Make the "File is a directory"
13699 error be more correct.
13701 * fns.c (Frequire): Remove the mention of the .gz files, since
13702 that's installation-specific, but keep the mention of
13703 `get-load-suffixes'.

13707 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

13718 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
13719 Also (re)move comments that are misplaced or no longer relevant.

13744 leave any prefix arg for the up event (Bug#1586).
13746 2011-07-02 Lars Magne Ingebrigtsen <larsi@gnus.org>
13748 * lread.c (syms_of_lread): Mention single symbols defined by
13749 `defvar' or `defconst' (bug#7154).
13751 * fns.c (Frequire): Mention .el.gz files (bug#7314).
13752 (Frequire): Mention get-load-suffixes.

13782 (syms_of_keymap): Defsubr make-composed-keymap.
13783 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

13820 * eval.c (struct backtrace): Simplify and port the data structure.
13821 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
13822 signed bit field, as this assumption is not portable and it makes
13823 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
13824 "char debug_on_exit : 1" as this is not portable either; instead,
13825 use the portable "unsigned int debug_on_exit : 1". Remove unused
13826 member evalargs. Remove obsolete comments about cc bombing out.
13828 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

13995 (PRINTPREPARE, printchar, strout):
13996 Don't set size unless allocation succeeds.
13998 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
13999 for sizes. Check for string overflow more accurately.

14003 * keyboard.h (struct keyboard.kbd_macro_bufsize):
14004 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

14010 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
14012 * lread.c: Integer overflow fixes.
14013 (read_integer): Radix is now EMACS_INT, not int,
14014 to improve quality of diagnostics for out-of-range radices.
14015 Calculate buffer size correctly for out-of-range radices.
14016 (read1): Check for integer overflow in radices, and in
14017 read-circle numbers.
14018 (read_escape): Avoid int overflow.
14019 (Fload, openp, read_buffer_size, read1)
14020 (substitute_object_recurse, read_vector, read_list, map_obarray):

14036 2011-06-22 Leo Liu <sdl.web@gmail.com>
14038 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
14039 Move to minibuffer.el.
14041 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
14043 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
14044 The following patches are for when GLYPH_DEBUG && !XASSERT.
14045 * dispextern.h (trace_redisplay_p, dump_glyph_string):
14046 * dispnew.c (flush_stdout):
14047 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
14048 Mark as externally visible.
14049 * dispnew.c (check_window_matrix_pointers): Now static.
14050 * dispnew.c (window_to_frame_vpos):
14051 * xfns.c (unwind_create_frame):
14052 * xterm.c (x_check_font): Remove unused local.
14053 * scroll.c (CHECK_BOUNDS):
14054 * xfaces.c (cache_fache): Rename local to avoid shadowing.
14055 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
14056 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
14057 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
14058 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
14060 (debug_method_add): Use va_list and vsprintf rather than relying
14061 on undefined behavior with wrong number of arguments.
14062 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
14063 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
14064 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
14065 since we're not interested in debugging glyphs with old libraries.
14066 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
14067 GCC 4.6.0's static checking.
14069 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
14071 Integer overflow and signedness fixes (Bug#8873).

14087 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
14088 (.bitmaps_last, struct x_output.icon_bitmap):
14089 Use ptrdiff_t, not int, for bitmap indexes.
14090 (x_allocate_bitmap_record): Check for size overflow.
14091 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
14093 Use ptrdiff_t, not int, for overlay counts.
14094 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
14095 * editfns.c (overlays_around, get_pos_property):

14098 * xfaces.c (face_at_buffer_position):
14099 * buffer.c (OVERLAY_COUNT_MAX): New macro.
14100 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
14101 (Fnext_overlay_change, Fprevious_overlay_change)
14102 (mouse_face_overlay_overlaps, Foverlays_in):
14103 Use ptrdiff_t, not int, for sizes.
14104 (overlays_at, overlays_in): Check for size-calculation overflow.
14106 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
14108 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
14109 (x_session_initialize): Do not assume string length fits in int.
14111 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
14112 This is unlikely, but can occur if DPI is outlandish.
14114 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
14115 * xselect.c (Fx_get_atom_name): Avoid need for strlen.

14118 * xrdb.c (magic_file_p, search_magic_path):
14119 Omit last arg SUFFIX; it was always 0. All callers changed.
14120 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
14122 * xfont.c (xfont_match): Avoid need for strlen.

14127 * xdisp.c (message_log_check_duplicate): Return intmax_t,
14128 not unsigned long, as we prefer signed integers. All callers changed.
14129 Detect integer overflow in repeat count.
14130 (message_dolog): Don't assume print length fits in 39 bytes.
14131 (display_mode_element): Don't assume strlen fits in int.
14133 * termcap.c: Don't assume sizes fit in int and never overflow.
14134 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
14135 (gobble_line): Check for size-calculation overflow.
14137 * minibuf.c (Fread_buffer):
14138 * lread.c (intern, intern_c_string):
14139 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:

14152 * filelock.c: Fix some buffer overrun and integer overflow issues.
14153 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
14154 Reformulate so as not to need the command string.
14155 Invoke gzip -cd rather than gunzip, as it's more portable.
14156 (lock_info_type, lock_file_1, lock_file):
14157 Don't assume pid_t and time_t fit in unsigned long.
14158 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
14159 (current_lock_owner): Prefer signed type for sizes.
14160 Use memcpy, not strncpy, where memcpy is what is really wanted.
14161 Don't assume (via atoi) that time_t and pid_t fit in int.
14162 Check for time_t and/or pid_t out of range, e.g., via a network share.
14163 Don't alloca where an auto var works fine.
14165 * fileio.c: Fix some integer overflow issues.
14166 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
14167 Don't assume string length fits in int.
14168 (directory_file_name): Don't assume string length fits in long.
14169 (make_temp_name): Don't assume pid fits in int, or that its print
14170 length is less than 20.

14189 (Fgetenv_internal):
14190 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
14192 * lread.c (invalid_syntax): Omit length argument.
14193 All uses changed. This doesn't fix a bug, but it simplifies the
14194 code away from its former Hollerith-constant appearance, and it's
14195 one less 'int' to worry about when looking at integer-overflow issues.
14196 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
14198 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
14199 This didn't break anything, but it didn't help either.
14200 It's confusing to put a bogus integer in a place where the actual
14201 value does not matter.
14202 (LIST_END_P): Remove unused macro and its bogus comment.
14203 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
14205 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
14206 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
14208 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
14209 We prefer signed types, and the value cannot exceed the EMACS_INT
14210 range anyway (because otherwise the length would not be representable).
14211 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
14212 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
14213 This avoids a GCC warning when WIDE_EMACS_INT.
14215 * indent.c (sane_tab_width): New function.
14216 (current_column, scan_for_column, Findent_to, position_indentation)
14217 (compute_motion): Use it. This is just for clarity.
14218 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
14220 * image.c (xbm_image_p): Don't assume stated width, height fit in int.

14223 * composite.c (composition_gstring_put_cache):
14224 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
14226 * editfns.c, insdel.c:
14227 Omit unnecessary forward decls, to simplify future changes.
14229 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
14231 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
14233 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
14234 Use much-faster test for byte-length change.
14235 Don't assume string byte-length fits in 'int'.
14236 Check that character arg fits in 'int'.
14237 (mapcar1): Declare byte as byte, for clarity.
14239 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
14241 * fns.c (concat): Catch string overflow earlier.
14242 Do not rely on integer wraparound.
14244 * dispextern.h (struct it.overlay_strings_charpos)
14245 (struct it.selective): Now EMACS_INT, not int.
14246 * xdisp.c (forward_to_next_line_start)
14247 (back_to_previous_visible_line_start)
14248 (reseat_at_next_visible_line_start, next_element_from_buffer):
14249 Don't arbitrarily truncate the value of 'selective' to int.
14251 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
14253 * composite.c: Don't truncate sizes to 'int'.
14254 (composition_gstring_p, composition_reseat_it)
14255 (composition_adjust_point): Use EMACS_INT, not int.
14256 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
14257 not EMACS_UINT, for indexes.
14259 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
14261 * buffer.c: Include <verify.h>.
14262 (struct sortvec.priority, struct sortstr.priority):
14263 Now EMACS_INT, not int.
14264 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
14265 (struct sortstr.size, record_overlay_string)
14266 (struct sortstrlist.size, struct sortlist.used):
14267 Don't truncate size to int.
14268 (record_overlay_string): Check for size-calculation overflow.
14269 (init_buffer_once): Check at compile-time, not run-time.
14271 2011-06-22 Jim Meyering <meyering@redhat.com>
14273 Don't leak an XBM-image-sized buffer
14274 * image.c (xbm_load): Free the image buffer after using it.
14276 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
14279 * composite.c (find_automatic_composition): Omit needless 'return 0;'
14280 that Sun C diagnosed.
14281 * fns.c (secure_hash): Fix pointer signedness issue.
14282 * intervals.c (static_offset_intervals): New function.
14283 (offset_intervals): Use it.
14285 2011-06-21 Leo Liu <sdl.web@gmail.com>
14288 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
14291 * fns.c (secure_hash): Rename from crypto_hash_function and change
14292 the first arg to accept symbols.
14293 (Fsecure_hash): New primitive.
14294 (syms_of_fns): New symbols.
14296 2011-06-20 Deniz Dogan <deniz@dogan.se>
14298 * process.c (Fset_process_buffer): Clarify return value in

14303 * dispnew.c (add_window_display_history): Use BVAR.
14305 * xdisp.c (debug_method_add): Use BVAR.
14306 (check_window_end, dump_glyph_matrix, dump_glyph)
14307 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
14309 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
14312 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
14313 check till after the cache is created in init_frame_faces.
14315 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
14317 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
14319 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
14321 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
14322 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
14323 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
14325 Improve buffer-overflow checking (Bug#8873).
14326 * fileio.c (Finsert_file_contents):
14327 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
14328 Remove the old (too-loose) buffer overflow checks.
14329 They weren't needed, since make_gap checks for buffer overflow.
14330 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
14331 The old code merely checked for Emacs fixnum overflow, and relied
14332 on undefined (wraparound) behavior. The new code avoids undefined
14333 behavior, and also checks for ptrdiff_t and/or size_t overflow.
14335 * editfns.c (Finsert_char): Don't dump core with very negative counts.
14336 Tune. Don't use wider integers than needed. Don't use alloca.
14337 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
14339 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
14341 * insdel.c, lisp.h (buffer_overflow): New function.
14342 (insert_from_buffer_1, replace_range, replace_range_2):
14343 * insdel.c (make_gap_larger):
14344 * editfns.c (Finsert_char):
14345 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
14347 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
14349 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
14351 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
14353 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
14354 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
14356 * fileio.c: Don't assume EMACS_INT fits in off_t.
14357 (emacs_lseek): New static function.
14358 (Finsert_file_contents, Fwrite_region): Use it.
14359 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
14361 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
14363 * fns.c: Don't overflow int when computing a list length.
14364 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
14365 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
14366 truncation on 64-bit hosts. Check for QUIT every
14367 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
14368 faster and is responsive enough.
14369 (Flength): Report an error instead of overflowing an integer.
14370 (Fsafe_length): Return a float if the value is not representable
14371 as a fixnum. This shouldn't happen except in contrived situations.
14372 (Fnthcdr, Fsort): Don't assume list length fits in int.
14373 (Fcopy_sequence): Don't assume vector length fits in int.
14375 * alloc.c: Check that resized vectors' lengths fit in fixnums.
14376 (header_size, word_size): New constants.
14377 (allocate_vectorlike): Don't check size overflow here.
14378 (allocate_vector): Check it here instead, since this is the only
14379 caller of allocate_vectorlike that could cause overflow.
14380 Check that the new vector's length is representable as a fixnum.
14382 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
14383 The previous code was bogus. For example, next_almost_prime (32)
14384 returned 39, which is undesirable as it is a multiple of 3; and
14385 next_almost_prime (24) returned 25, which is a multiple of 5 so
14386 why was the code bothering to check for multiples of 7?
14388 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
14390 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
14392 Variadic C functions now count arguments with ptrdiff_t.
14393 This partly undoes my 2011-03-30 change, which replaced int with size_t.
14394 Back then I didn't know that the Emacs coding style prefers signed int.
14395 Also, in the meantime I found a few more instances where arguments
14396 were being counted with int, which may truncate counts on 64-bit
14397 machines, or EMACS_INT, which may be unnecessarily wide.
14398 * lisp.h (struct Lisp_Subr.function.aMANY)
14399 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
14400 Arg counts are now ptrdiff_t, not size_t.
14401 All variadic functions and their callers changed accordingly.
14402 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
14403 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
14404 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
14405 * callint.c (Fcall_interactively): Check arg count for overflow,
14406 to avoid potential buffer overrun. Use signed char, not 'int',
14407 for 'varies' array, so that we needn't bother to check its size
14408 calculation for overflow.
14409 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
14410 * eval.c (apply_lambda):
14411 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
14412 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
14413 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
14415 * callint.c (Fcall_interactively): Don't use index var as event count.
14417 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
14418 * mem-limits.h (SIZE): Remove; no longer used.
14420 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
14422 Remove unnecessary casts.
14423 * xterm.c (x_term_init):
14424 * xfns.c (x_set_border_pixel):
14425 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
14426 These aren't needed now that we assume ANSI C.
14428 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
14429 It's more likely to cause problems (due to unsigned overflow)
14432 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
14434 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
14436 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
14438 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
14440 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
14442 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
14444 GLYPH_CODE_FACE returns EMACS_INT, not int.
14445 * dispextern.h (merge_faces):
14446 * xfaces.c (merge_faces):
14447 * xdisp.c (get_next_display_element, next_element_from_display_vector):
14448 Don't assume EMACS_INT fits in int.
14450 * character.h (CHAR_VALID_P): Remove unused parameter.
14451 * fontset.c, lisp.h, xdisp.c: All uses changed.
14453 * editfns.c (Ftranslate_region_internal): Omit redundant test.
14455 * fns.c (concat): Minor tuning based on overflow analysis.
14456 This doesn't fix any bugs. Use int to hold character, instead
14457 of constantly refetching from Emacs object. Use XFASTINT, not
14458 XINT, for value known to be a character. Don't bother comparing
14459 a single byte to 0400, as it's always less.
14461 * floatfns.c (Fexpt):
14462 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
14464 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
14467 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
14469 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
14470 Without this fix, on a 64-bit host (aset S 0 4294967386) would
14471 incorrectly succeed when S was a string, because 4294967386 was
14472 truncated before it was used.
14474 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
14475 Otherwise, an out-of-range integer could cause undefined behavior
14478 * composite.c: Use int, not EMACS_INT, for characters.
14479 (fill_gstring_body, composition_compute_stop_pos): Use int, not
14480 EMACS_INT, for values that are known to be in character range.
14481 This doesn't fix any bugs but is the usual style inside Emacs and
14482 may generate better code on 32-bit machines.
14484 Make sure a 64-bit char is never passed to ENCODE_CHAR.
14485 This is for reasons similar to the recent CHAR_STRING fix.
14486 * charset.c (Fencode_char): Check that character arg is actually
14487 a character. Pass an int to ENCODE_CHAR.
14488 * charset.h (ENCODE_CHAR): Verify that the character argument is no
14489 wider than 'int', as a compile-time check to prevent future regressions
14492 * character.c (char_string): Remove unnecessary casts.
14494 Make sure a 64-bit char is never passed to CHAR_STRING.
14495 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
14496 by silently ignoring the top 32 bits, allowing some values
14497 that were far too large to be valid characters.
14498 * character.h: Include <verify.h>.
14499 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
14500 arguments are no wider than unsigned, as a compile-time check
14501 to prevent future regressions in this area.
14503 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
14504 (Fsubst_char_in_region):
14506 * xdisp.c (decode_mode_spec_coding):
14507 Adjust to CHAR_STRING's new requirement.
14508 * editfns.c (Finsert_char, Fsubst_char_in_region):
14509 * fns.c (concat): Check that character args are actually
14510 characters. Without this test, these functions did the wrong
14511 thing with wildly out-of-range values on 64-bit hosts.
14513 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
14514 These casts should not be needed on 32-bit hosts, either.
14515 * keyboard.c (read_char):
14516 * lread.c (Fload): Remove casts to unsigned.
14518 * lisp.h (UNSIGNED_CMP): New macro.
14519 This fixes comparison bugs on 64-bit hosts.
14520 (ASCII_CHAR_P): Use it.
14521 * casefiddle.c (casify_object):
14522 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
14523 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
14524 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
14525 * dispextern.h (FACE_FROM_ID):
14526 * keyboard.c (read_char): Use UNSIGNED_CMP.
14528 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
14529 not to EMACS_INT, to avoid GCC warning.
14531 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
14533 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
14534 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
14535 isn't needed on 32-bit machines.
14537 * buffer.c (Fgenerate_new_buffer_name):
14538 Use EMACS_INT for count, not int.
14539 (advance_to_char_boundary): Return EMACS_INT, not int.
14541 * data.c (Qcompiled_function): Now static.
14543 * window.c (window_body_lines): Now static.
14545 * image.c (gif_load): Rename local to avoid shadowing.
14547 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
14548 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
14549 * alloc.c (make_save_value): Integer argument is now of type
14550 ptrdiff_t, not int.
14551 (mark_object): Use ptrdiff_t, not int.
14552 * lisp.h (pD): New macro.
14553 * print.c (print_object): Use it.
14555 * alloc.c: Use EMACS_INT, not int, to count objects.
14556 (total_conses, total_markers, total_symbols, total_vector_size)
14557 (total_free_conses, total_free_markers, total_free_symbols)
14558 (total_free_floats, total_floats, total_free_intervals)
14559 (total_intervals, total_strings, total_free_strings):
14560 Now EMACS_INT, not int. All uses changed.
14561 (Fgarbage_collect): Compute overall total using a double, so that
14562 integer overflow is less likely to be a problem. Check for overflow
14563 when converting back to an integer.
14564 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
14565 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
14566 These were 'int' variables that could overflow on 64-bit hosts;
14567 they were never used, so remove them instead of repairing them.
14568 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
14569 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
14570 Previously, this ceilinged at INT_MAX, but that doesn't work on
14572 (allocate_pseudovector): Don't use EMACS_INT when int would do.
14574 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
14575 (allocate_vectorlike): Check for ptrdiff_t overflow.
14576 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
14577 when a (possibly-narrower) signed value would do just as well.
14578 We prefer using signed arithmetic, to avoid comparison confusion.
14580 * alloc.c: Catch some string size overflows that we were missing.
14581 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
14582 for convenience in STRING_BYTES_MAX.
14583 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
14584 The definition here is exact; the one in lisp.h was approximate.
14585 (allocate_string_data): Check for string overflow. This catches
14586 some instances we weren't catching before. Also, it catches
14587 size_t overflow on (unusual) hosts where SIZE_MAX <= min
14588 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
14589 and ptrdiff_t and EMACS_INT are both 64 bits.
14591 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
14592 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
14593 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
14595 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
14597 * alloc.c (Fmake_string): Check for out-of-range init.
14599 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
14601 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
14603 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
14605 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
14606 xg_get_default_scrollbar_width.
14608 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
14609 (int_gtk_range_get_value): Move to the scroll bar part of the file.
14610 (style_changed_cb): Call update_theme_scrollbar_width and call
14611 x_set_scroll_bar_default_width and xg_frame_set_char_size for
14612 all frames (Bug#8505).
14613 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
14614 Call gtk_window_set_resizable if HAVE_GTK3.
14615 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
14616 and height if HAVE_GTK3 (Bug#8505).
14617 (scroll_bar_width_for_theme): New variable.
14618 (update_theme_scrollbar_width): New function.
14619 (xg_get_default_scrollbar_width): Move code to
14620 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
14621 (xg_initialize): Call update_theme_scrollbar_width.
14623 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
14625 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
14627 2011-06-12 Martin Rudalics <rudalics@gmx.at>
14629 * frame.c (make_frame): Call other_buffer_safely instead of
14632 * window.c (temp_output_buffer_show): Call display_buffer with
14633 second argument Vtemp_buffer_show_specifiers and reset latter
14634 immediately after the call.
14635 (Vtemp_buffer_show_specifiers): New variable.
14636 (auto_window_vscroll_p, next_screen_context_lines)
14637 (Vscroll_preserve_screen_position): Remove leading asterisks from
14640 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
14642 Fix minor problems found by GCC 4.6.0 static checking.
14643 * buffer.c (Qclone_number): Remove for now, as it's unused.
14644 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
14645 (record_buffer): Remove unused local.
14646 * frame.c (other_visible_frames, frame_buffer_list): Now static.
14647 (set_frame_buffer_list): Remove; unused.
14648 * frame.h (other_visible_frames): Remove decl.
14649 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
14650 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
14651 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
14653 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
14654 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
14655 Define only if HAVE_GPM.
14656 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
14657 (update_hints_inhibit): Remove; never set. All uses removed.
14658 * widgetprv.h (emacsFrameClassRec): Remove decl.
14659 * window.c (delete_deletable_window): Now returns void, since it
14660 wasn't returning anything.
14661 (compare_window_configurations): Remove unused locals.
14662 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
14663 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
14664 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
14665 the same widths as pointers. This follows up on the 2011-05-06 patch.
14666 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
14667 * xterm.h: Likewise.
14668 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.
14670 2011-06-12 Juanma Barranquero <lekktu@gmail.com>
14672 * makefile.w32-in: Update dependencies.
14673 (LISP_H): Add lib/intprops.h.
14675 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
14677 * image.c (gif_load): Add animation frame delay to the metadata.
14678 (syms_of_image): Use DEFSYM. New symbol `delay'.
14680 2011-06-11 Martin Rudalics <rudalics@gmx.at>
14682 * window.c (delete_deletable_window): Re-add.
14683 (Fset_window_configuration): Rewrite to handle dead buffers and
14684 consequently deletable windows.
14685 (window_tree, Fwindow_tree): Remove. Supply functionality in
14687 (compare_window_configurations): Simplify code.
14689 2011-06-11 Andreas Schwab <schwab@linux-m68k.org>
14691 * image.c (imagemagick_load_image): Fix type mismatch.
14692 (Fimagemagick_types): Likewise.
14694 * window.h (replace_buffer_in_windows): Declare.
14696 2011-06-11 Martin Rudalics <rudalics@gmx.at>
14698 * buffer.c: New Lisp objects Qbuffer_list_update_hook and
14699 Qclone_number. Remove external declaration of Qdelete_window.
14700 (Fbuffer_list): Rewrite doc-string. Minor restructuring of
14702 (Fget_buffer_create, Fmake_indirect_buffer, Frename_buffer):
14703 Run Qbuffer_list_update_hook if allowed.
14704 (Fother_buffer): Rewrite doc-string. Major rewrite for new
14705 buffer list implementation.
14706 (other_buffer_safely): New function.
14707 (Fkill_buffer): Replace call to replace_buffer_in_all_windows by
14708 calls to replace_buffer_in_windows and
14709 replace_buffer_in_windows_safely. Run Qbuffer_list_update_hook
14711 (record_buffer): Inhibit quitting and rewrite using quittable
14712 functions. Run Qbuffer_list_update_hook if allowed.
14713 (Frecord_buffer, Funrecord_buffer): New functions.
14714 (switch_to_buffer_1, Fswitch_to_buffer): Remove.
14715 Move switch-to-buffer to window.el.
14716 (bury-buffer): Move to window.el.
14717 (Vbuffer_list_update_hook): New variable.
14719 * lisp.h (other_buffer_safely): Add prototype in buffer.c
14722 * window.h (resize_frame_windows): Move up in code.
14723 (Fwindow_frame): Remove EXFUN.
14724 (replace_buffer_in_all_windows): Remove prototype.
14725 (replace_buffer_in_windows_safely): Add prototype.
14727 * window.c: Declare Qdelete_window static again. Move down
14728 declaration of select_count.
14729 (Fnext_window, Fprevious_window): Rewrite doc-strings.
14730 (Fother_window): Move to window.el.
14731 (window_loop): Remove DELETE_BUFFER_WINDOWS and UNSHOW_BUFFER
14732 cases. Add REPLACE_BUFFER_IN_WINDOWS_SAFELY case.
14733 (Fdelete_windows_on, Freplace_buffer_in_windows): Move to
14735 (replace_buffer_in_windows): Implement by calling

15182 were just reseat()'ed to a new position.
15184 * xdisp.c (set_cursor_from_row): Set start and stop points
15185 according to the row's direction when priming the loop that looks
15186 for the glyph on which to display cursor.
15187 (single_display_spec_intangible_p): Function deleted.
15188 (display_prop_intangible_p): Reimplement to call
15189 handle_display_spec instead of single_display_spec_intangible_p.
15190 Accept 3 additional arguments needed by handle_display_spec.
15191 This fixes incorrect cursor motion across display property with complex
15192 values: lists, `(when COND...)' forms, etc.
15193 (single_display_spec_string_p): Support property values that are
15194 lists with the argument STRING its top-level element.
15195 (display_prop_string_p): Fix the condition for processing a
15196 property that is a list to be consistent with handle_display_spec.
15197 (handle_display_spec): New function, refactored from the
15198 last portion of handle_display_prop.
15199 (compute_display_string_pos): Accept additional argument
15200 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
15201 value of a `display' property is a "replacing spec".
15202 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
15203 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
15204 the display property, but just return a value indicating whether
15205 the display property will replace the characters it covers.
15206 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
15207 frame_window_p members of struct bidi_it.
15208 (compute_display_string_pos, compute_display_string_end):
15210 (push_it): Accept second argument POSITION, where pop_it should
15211 jump to continue iteration.
15212 (reseat_1): Initialize bidi_it.disp_pos.
15214 * keyboard.c (adjust_point_for_property): Adjust the call to
15215 display_prop_intangible_p to its new signature.
15217 * dispextern.h (struct bidi_it): New member frame_window_p.
15218 (bidi_init_it): Update prototypes.
15219 (display_prop_intangible_p): Update prototype.
15220 (compute_display_string_pos, compute_display_string_end):
15221 Declare prototypes.
15222 (struct bidi_it): New members nchars and disp_pos. ch_len is now
15225 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
15227 Malloc failure behavior now depends on size of allocation.
15228 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
15229 * lisp.h: Change signatures accordingly.
15230 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
15231 All callers changed. (Bug#8762)
15233 * gnutls.c: Use Emacs's memory allocators.
15234 Without this change, the gnutls library would invoke malloc etc.
15235 directly, which causes problems on non-SYNC_INPUT hosts, and which
15236 runs afoul of improving memory_full behavior. (Bug#8761)
15237 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
15238 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
15239 xfree instead of the default malloc, realloc, free.
15240 (Fgnutls_boot): No need to check for memory allocation failure,
15241 since xmalloc does that for us.
15243 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
15244 * category.c (hash_get_category_set):
15245 * ccl.c (ccl_driver):

15253 (cmpfn_equal, cmpfn_user_defined, hashfn_eq, hashfn_eql)
15254 (hashfn_equal, hashfn_user_defined, make_hash_table)

15257 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
15258 (Fsxhash, Fgethash, Fputhash, Fmaphash):
15259 * image.c (make_image, search_image_cache, lookup_image)
15260 (xpm_put_color_table_h):
15261 * lisp.h (struct Lisp_Hash_Table):
15262 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
15263 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
15264 for hashes and hash indexes, instead of 'unsigned' and 'int'.
15265 * alloc.c (allocate_vectorlike):
15266 Check for overflow in vector size calculations.
15267 * ccl.c (ccl_driver):
15268 Check for overflow when converting EMACS_INT to int.
15269 * fns.c, image.c: Remove unnecessary static decls that would otherwise
15270 need to be updated by these changes.
15271 * fns.c (make_hash_table, maybe_resize_hash_table):
15272 Check for integer overflow with large hash tables.
15273 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
15274 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
15275 (SXHASH_REDUCE): New macro.
15276 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
15277 Use it instead of discarding useful hash info with large hash values.
15278 (sxhash_float): New function.
15279 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
15280 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
15281 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
15282 Rewrite to use FIXNUM_BITS, as this simplifies things.
15283 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
15284 Adjust signatures to match updated version of code.
15285 (consing_since_gc): Now EMACS_INT, since a single hash table can
15286 use more than INT_MAX bytes.
15288 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
15290 Make it possible to build with GCC-4.6+ -O2 -flto.
15292 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
15294 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
15296 * minibuf.c (get_minibuffer, read_minibuf_unwind):
15297 Call minibuffer-inactive-mode.
15299 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
15301 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
15302 Update dependencies.
15304 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
15306 * data.c (init_data): Remove code for UTS, this system is not
15309 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
15311 Don't force ./temacs to start in terminal mode.
15313 * frame.c (make_initial_frame): Initialize faces in all cases, not
15314 only when CANNOT_DUMP is defined.
15315 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
15317 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
15319 * dispnew.c (add_window_display_history): Use const for the string
15320 pointer. Remove declaration, not needed.
15322 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
15324 Use 'inline', not 'INLINE'.
15325 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
15326 * alloc.c, fontset.c (INLINE): Remove.
15327 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
15328 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
15329 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
15330 * gmalloc.c (register_heapinfo): Use inline unconditionally.
15331 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
15333 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
15335 Make it possible to run ./temacs.
15337 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
15338 syms_of_callproc does the same thing. Remove test for
15339 "initialized", do it in the caller.
15340 * emacs.c (main): Avoid calling set_initial_environment when dumping.
15342 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
15344 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
15345 (read_minibuf): Use get_minibuffer.
15346 (syms_of_minibuf): Use DEFSYM.
15347 (Qmetadata): New var.
15348 * data.c (Qbuffer): Don't make it static.
15349 (syms_of_data): Use DEFSYM.
15351 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
15353 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
15354 (CCL_CODE_MIN): New macro.
15356 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
15358 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
15360 * eval.c (Qdebug): Now static.
15361 * lisp.h (Qdebug): Remove decl. This reverts a part of the
15362 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
15363 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
15365 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
15367 * image.c: Various fixes to ImageMagick code comments.
15368 (Fimagemagick_types): Doc fix.
15370 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
15372 Minor fixes prompted by GCC 4.6.0 warnings.
15374 * xselect.c (converted_selections, conversion_fail_tag): Now static.
15376 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
15377 (x_clipboard_manager_save_all): Move extern decl to ...
15378 * xterm.h: ... here, so that it can be checked for consistency.
15380 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
15382 * xselect.c (x_clipboard_manager_save_frame)
15383 (x_clipboard_manager_save_all): New functions.
15384 (Fx_clipboard_manager_save): Lisp function deleted.
15386 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
15387 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
15389 * xterm.h: Update prototype.
15391 2011-05-28 William Xu <william.xwl@gmail.com>
15393 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
15394 exiting (Bug#8239).
15396 2011-05-28 Jim Meyering <meyering@redhat.com>
15398 Avoid a sign-extension bug in crypto_hash_function.
15399 * fns.c (to_uchar): Define.
15400 (crypto_hash_function): Use it to convert some newly-signed
15401 variables to unsigned, to avoid sign-extension bugs. For example,
15402 without this change, (md5 "truc") would evaluate to
15403 45723a2aff78ff4fff7fff1114760e62 rather than the expected
15404 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
15405 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
15407 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
15409 Integer overflow fixes.
15411 * dbusbind.c: Serial number integer overflow fixes.
15412 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
15413 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
15414 to hold a serial number that is too large for a fixnum.
15415 (Fdbus_method_return_internal, Fdbus_method_error_internal):
15416 Check for serial numbers out of range. Decode any serial number
15417 that was so large that it became a float. (Bug#8722)
15419 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
15420 (Fdbus_call_method, Fdbus_call_method_asynchronously):
15421 Use XFASTINT rather than XUINT when numbers are nonnegative.
15422 (xd_append_arg, Fdbus_method_return_internal):
15423 (Fdbus_method_error_internal): Likewise. Also, for unsigned
15424 arguments, check that Lisp number is nonnegative, rather than
15425 silently wrapping negative numbers around. (Bug#8722)
15426 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
15429 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
15431 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
15433 ccl: Add integer overflow checks.
15434 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
15435 (IN_INT_RANGE): New macros.
15436 (ccl_driver): Use them to check for integer overflow when
15437 decoding a CCL program. Many of the new checks are whether XINT (x)
15438 fits in int; it doesn't always, on 64-bit hosts. The new version
15439 doesn't catch all possible integer overflows, but it's an
15440 improvement. (Bug#8719)
15442 * alloc.c (make_event_array): Use XINT, not XUINT.
15443 There's no need for unsigned here.
15445 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
15446 This follows up to the 2011-05-06 change that substituted uintptr_t
15447 for EMACS_INT. This case wasn't caught back then.
15449 Rework Fformat to avoid integer overflow issues.
15450 * editfns.c: Include <float.h> unconditionally, as it's everywhere
15451 now (part of C89). Include <verify.h>.
15452 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
15453 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
15454 (Fformat): Avoid the prepass trying to compute sizes; it was only
15455 approximate and thus did not catch overflow reliably. Instead, walk
15456 through the format just once, formatting and computing sizes as we go,
15457 checking for integer overflow at every step, and allocating a larger
15458 buffer as needed. Keep track separately whether the format is
15459 multibyte. Keep only the most-recently calculated precision, rather
15460 than them all. Record whether each argument has been converted to
15461 string. Use EMACS_INT, not int, for byte and char and arg counts.
15462 Support field widths and precisions larger than INT_MAX. Avoid
15463 sprintf's undefined behavior with conversion specifications such as %#d
15464 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
15465 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
15466 formatting out-of-range floating point numbers with int
15467 formats. (Bug#8668)
15469 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
15471 * data.c: Avoid integer truncation in expressions involving floats.
15472 * data.c: Include <intprops.h>.
15473 (arith_driver): When there's an integer overflow in an expression
15474 involving floating point, convert the integers to floating point
15475 so that the resulting value does not suffer from catastrophic
15476 integer truncation. For example, on a 64-bit host (* 4
15477 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
15478 Do not rely on undefined behavior after integer overflow.
15480 merge count_size_as_multibyte, parse_str_to_multibyte
15481 * character.c, character.h (count_size_as_multibyte):
15482 Rename from parse_str_to_multibyte; all uses changed.
15483 Check for integer overflow.
15484 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
15485 since it's now a duplicate of the other. This is more of
15486 a character than a buffer op, so better that it's in character.c.
15487 * fns.c, print.c: Adjust to above changes.
15489 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
15491 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
15493 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
15495 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
15496 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
15497 (x_clipboard_manager_save): Now static.
15498 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
15500 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
15501 (crypto_hash_function): Now static.
15502 Fix pointer signedness problems. Avoid unnecessary initializations.
15504 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
15506 * termhooks.h (Vselection_alist): Make it terminal-local.
15508 * terminal.c (create_terminal): Initialize it.
15510 * xselect.c: Support for clipboard managers.
15511 (Vselection_alist): Move to termhooks.h as terminal-local var.
15512 (LOCAL_SELECTION): New macro.
15513 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
15514 (symbol_to_x_atom): Remove gratuitous arg.
15515 (x_handle_selection_request, lisp_data_to_selection_data)
15516 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
15517 (x_own_selection, x_get_local_selection, x_convert_selection):
15518 New arg, specifying work frame. Use terminal-local Vselection_alist.
15519 (some_frame_on_display): Delete unused function.
15520 (Fx_own_selection_internal, Fx_get_selection_internal)
15521 (Fx_disown_selection_internal, Fx_selection_owner_p)
15522 (Fx_selection_exists_p): New optional frame arg.
15523 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
15524 (x_handle_selection_clear): Don't treat other terminals with the
15525 same keyboard specially. Use the terminal-local Vselection_alist.
15526 (x_clear_frame_selections): Use Frun_hook_with_args.
15528 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
15530 * xterm.h: Add support for those atoms.
15532 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
15534 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
15535 (converted_selections, conversion_fail_tag): New global variables.
15536 (x_selection_request_lisp_error): Free the above.
15537 (x_get_local_selection): Remove unnecessary code.
15538 (x_reply_selection_request): Args changed; handle arbitrary array
15539 of converted selections stored in converted_selections.
15540 Separate the XChangeProperty and SelectionNotify steps.
15541 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
15542 (x_convert_selection): New function.
15543 (x_handle_selection_event): Simplify.
15544 (x_get_foreign_selection): Don't ignore incoming requests while
15545 waiting for an answer; this will fail when we implement
15546 SAVE_TARGETS, and seems unnecessary anyway.
15547 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
15548 (Vx_sent_selection_functions): Doc fix.
15550 2011-05-26 Leo Liu <sdl.web@gmail.com>
15552 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
15554 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15556 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
15558 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
15559 for fringe update if it has periodic bitmap.
15560 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
15561 and fringe_bitmap_periodic_p.
15563 * fringe.c (get_fringe_bitmap_data): New function.
15564 (draw_fringe_bitmap_1, update_window_fringes): Use it.
15565 (update_window_fringes): Record periodicity of fringe bitmap in glyph
15566 row. Mark glyph row for fringe update if periodicity changed.
15568 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
15569 for fringe update unless it has periodic bitmap.
15571 2011-05-25 Kenichi Handa <handa@m17n.org>
15573 * xdisp.c (get_next_display_element): Set correct it->face_id for
15574 a static composition.

15588 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
15589 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
15590 Remove macros that are defined and never used.
15591 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
15593 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
15595 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
15596 (Fx_get_selection_internal): Minor cleanup.
15597 (Fx_own_selection_internal): Rename arguments for consistency with

15611 last enabled row in the desired matrix touches the bottom boundary.
15613 2011-05-21 Glenn Morris <rgm@gnu.org>
15615 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
15616 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
15617 and add some more files.
15619 2011-05-20 Eli Zaretskii <eliz@gnu.org>
15621 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
15622 report_file_error introduced by the change from 2011-05-07.
15624 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
15626 * systime.h (Time): Define only if emacs is defined.
15627 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
15628 where the include path doesn't have X11/X.h by default. See
15629 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
15631 2011-05-20 Kenichi Handa <handa@m17n.org>
15633 * composite.c (find_automatic_composition): Fix previous change.
15635 2011-05-20 Glenn Morris <rgm@gnu.org>
15637 * lisp.mk: New file, split from Makefile.in.
15638 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
15639 (shortlisp): Remove.
15640 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
15642 2011-05-19 Glenn Morris <rgm@gnu.org>
15644 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
15645 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
15646 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
15647 (lisp): Set the order to that of loadup.el.
15648 (shortlisp): Make it a copy of $lisp.
15649 (SOME_MACHINE_LISP): Remove.
15650 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
15651 Use just $shortlisp, not $SOME_MACHINE_LISP too.
15653 2011-05-18 Kenichi Handa <handa@m17n.org>
15655 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
15656 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
15657 (find_automatic_composition): Mostly rewrite for efficiency.
15659 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
15661 * makefile.w32-in: Update dependencies.
15663 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
15665 * menu.c: Include limits.h (fixes the MS-Windows build broken by
15666 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
15668 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
15670 Fix some integer overflow issues, such as string length overflow.
15672 * insdel.c (count_size_as_multibyte): Check for string overflow.
15674 * character.c (lisp_string_width): Check for string overflow.
15675 Use EMACS_INT, not int, for string indexes and lengths; in
15676 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
15677 the resulting string length overflows an EMACS_INT; instead,
15678 report a string overflow if no precision given. When checking for
15679 precision exhaustion, use a check that cannot possibly have
15680 integer overflow. (Bug#8675)
15681 * character.h (lisp_string_width): Adjust to new signature.
15683 * alloc.c (string_overflow): New function.
15684 (Fmake_string): Use it. This doesn't change behavior, but saves
15685 a few bytes and will simplify future changes.
15686 * character.c (string_escape_byte8): Likewise.
15687 * lisp.h (string_overflow): New decl.
15689 Fixups, following up to the user-interface timestamp change.
15690 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
15691 for UI timestamps, instead of unsigned long.
15692 * msdos.c (mouse_get_pos): Likewise.
15693 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
15694 * w32gui.h (Time): Define by including "systime.h" rather than by
15695 declaring it ourselves. (Bug#8664)
15697 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
15698 * image.c (clear_image_cache): Likewise.
15700 * term.c (term_mouse_position): Don't assume time_t wraparound.
15702 Be more systematic about user-interface timestamps.
15703 Before, the code sometimes used 'Time', sometimes 'unsigned long',
15704 and sometimes 'EMACS_UINT', to represent these timestamps.
15705 This change causes it to use 'Time' uniformly, as that's what X uses.
15706 This makes the code easier to follow, and makes it easier to catch
15707 integer overflow bugs such as Bug#8664.
15708 * frame.c (Fmouse_position, Fmouse_pixel_position):
15709 Use Time, not unsigned long, for user-interface timestamps.
15710 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
15711 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
15712 * keyboard.h (last_event_timestamp): Likewise.
15713 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
15714 * menu.h (xmenu_show): Likewise.
15715 * term.c (term_mouse_position): Likewise.
15716 * termhooks.h (struct input_event.timestamp): Likewise.
15717 (struct terminal.mouse_position_hook): Likewise.
15718 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
15719 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
15720 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
15721 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
15722 what it was before.
15723 * menu.h, termhooks.h: Include "systime.h", for Time.
15725 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
15726 Don't assume that the difference between two unsigned long values
15727 can fit into an integer. At this point, we know button_down_time
15728 <= event->timestamp, so the difference must be nonnegative, so
15729 there's no need to cast the result if double-click-time is
15730 nonnegative, as it should be; check that it's nonnegative, just in
15731 case. This bug is triggered when events are more than 2**31 ms
15732 apart (about 25 days). (Bug#8664)
15734 * xselect.c (last_event_timestamp): Remove duplicate decl.
15735 (x_own_selection): Remove needless cast to unsigned long.
15737 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
15738 that always fit in int. Use a sentinel instead of a counter, to
15739 avoid a temp and to allay GCC's concerns about possible int overflow.
15740 * frame.h (struct frame): Use int for menu_bar_items_used
15741 instead of EMACS_INT, since it always fits in int.
15743 * menu.c (grow_menu_items): Check for int overflow.
15745 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
15747 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
15748 Before, the code was not consistent. These values cannot exceed
15749 2**31 - 1 so there's no need to make them unsigned.
15750 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
15751 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
15752 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
15754 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
15756 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
15757 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
15758 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
15759 presumably because the widths might not match.
15761 * window.c (size_window): Avoid needless test at loop start.
15763 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
15765 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
15767 2011-05-12 Drew Adams <drew.adams@oracle.com>
15769 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
15771 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15773 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
15774 `width' to `bar_area_x' and `bar_area_width', respectively.
15775 (x_scroll_run): Take account of fringe background extension.
15777 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
15778 Rename local vars `left' and `width' to `bar_area_x' and
15779 `bar_area_width', respectively.
15780 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
15781 background extension.
15783 2011-05-10 Jim Meyering <meyering@redhat.com>
15785 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
15787 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
15789 * image.c (Finit_image_library): Return t for built-in image types,
15790 like pbm and xbm. (Bug#8640)
15792 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
15794 * w32menu.c (set_frame_menubar): Fix submenu allocation.
15796 2011-05-07 Eli Zaretskii <eliz@gnu.org>
15798 * w32console.c (Fset_screen_color): Doc fix.
15799 (Fget_screen_color): New function.
15800 (syms_of_ntterm): Defsubr it.
15802 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
15803 unlink the temporary file if Fcall_process didn't create it in the
15805 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
15806 child process will be redirected to a file specified with `:file'.
15807 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
15808 cue to call_process_cleanup not to close that handle.
15810 2011-05-07 Ben Key <bkey76@gmail.com>
15812 * makefile.w32-in: The bootstrap-temacs rule now makes use of
15813 one of two shell specific rules, either bootstrap-temacs-CMD or
15814 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
15815 to the previous implementation of the bootstrap-temacs rule.
15816 The bootstrap-temacs-CMD rule is similar to the previous
15817 implementation of the bootstrap-temacs rule except that it
15818 makes use of the ESC_CFLAGS variable instead of the CFLAGS
15821 These changes, along with some changes to nt/configure.bat,
15822 nt/gmake.defs, and nt/nmake.defs, are required to extend my
15823 earlier fix to add support for --cflags and --ldflags options
15824 that include quotes so that it works whether make uses cmd or
15827 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
15829 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
15830 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
15832 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
15833 a string. Handle both cases.
15834 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
15835 (Fdbus_register_method): Use Qinvalid_function.
15837 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
15839 * makefile.w32-in: Update dependencies.
15840 (LISP_H): Add inttypes.h and stdin.h.
15841 (PROCESS_H): Add unistd.h.
15843 2011-05-06 Eli Zaretskii <eliz@gnu.org>
15845 * lread.c: Include limits.h (fixes the MS-Windows build broken by
15846 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
15848 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
15850 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
15852 * term.c (vfatal): Remove stray call to va_end.
15853 It's not needed and the C Standard doesn't allow it here anyway.
15855 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
15856 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
15858 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
15861 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
15863 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
15865 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
15867 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
15869 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
15871 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
15872 * charset.c (Fdefine_charset_internal): Don't initialize
15873 charset.code_space[15]. The value was garbage, on hosts with
15874 32-bit int (Bug#8600).
15876 * lread.c (read_integer): Be more consistent with string-to-number.
15877 Use string_to_number to do the actual conversion; this avoids
15878 rounding errors and fixes some other screwups. Without this fix,
15879 for example, #x1fffffffffffffff was misread as -2305843009213693952.
15880 (digit_to_number): Move earlier, for benefit of read_integer.
15881 Return -1 if the digit is out of range for the base, -2 if it is
15882 not a digit in any supported base. (Bug#8602)
15884 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
15886 * dispnew.c (scrolling_window): Return 1 if we scrolled,
15887 to match comment at start of function. This also removes a
15888 GCC warning about overflow in a 32+64-bit port.
15890 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
15892 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
15893 Reported by Stefan Monnier in
15894 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
15895 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
15896 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
15898 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
15899 (EMACS_UINTPTR): Likewise, with uintptr_t.
15901 * lisp.h: Prefer 64-bit EMACS_INT if available.
15902 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
15903 on 32-bit hosts that have 64-bit int, so that they can access
15905 However, temporarily disable this change unless the temporary
15906 symbol WIDE_EMACS_INT is defined.
15908 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
15910 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
15911 This removes an assumption that EMACS_INT and long are the same
15912 width as pointers. The assumption is true for Emacs porting targets
15913 now, but we want to make other targets possible.
15914 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
15915 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
15916 In the rest of the code, change types of integers that hold casted
15917 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
15918 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
15919 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
15920 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
15921 No need to cast type when ORing.
15922 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
15923 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
15924 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
15925 assume EMACS_INT is the same width as char *.
15926 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
15927 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
15928 Remove no-longer-needed casts.
15929 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
15930 (xg_tool_bar_help_callback, xg_make_tool_item):
15931 Use EMACS_INTPTR to hold an integer
15932 that will be cast to void *; this can avoid a GCC warning
15933 if EMACS_INT is not the same width as void *.
15934 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
15935 * xdisp.c (display_echo_area_1, resize_mini_window_1):
15936 (current_message_1, set_message_1):
15937 Use a local to convert to proper width without a cast.
15938 * xmenu.c (dialog_selection_callback): Likewise.
15940 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
15941 Also, don't assume VALBITS / RAND_BITS is less than 5,
15942 and don't rely on undefined behavior when shifting a 1 left into
15944 * lisp.h (get_random): Change signature to match.
15946 * lread.c (hash_string): Use size_t, not int, for hash computation.
15947 Normally we prefer signed values; but hashing is special, because
15948 it's better to use unsigned division on hash table sizes so that
15949 the remainder is nonnegative. Also, size_t is the natural width
15950 for hashing into memory. The previous code used 'int', which doesn't
15951 retain enough info to hash well into very large tables.
15952 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
15954 * dbusbind.c: Don't possibly lose pointer info when converting.
15955 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
15956 Use XPNTR rather than XHASH, so that the high-order bits of
15957 the pointer aren't lost when converting through void *.
15959 * eval.c (Fautoload): Don't double-shift a pointer.
15961 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
15963 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
15965 * gnutls.c (DEF_GNUTLS_FN):
15966 * image.c (DEF_IMGLIB_FN): Make function pointers static.
15968 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
15970 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
15973 2011-05-05 Eli Zaretskii <eliz@gnu.org>
15975 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
15976 New version that can reserve upto 2GB of heap space.
15978 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
15980 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
15982 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
15984 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
15985 `gnutls_certificate_set_x509_key_file'.
15987 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
15989 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
15990 Update dependencies.
15992 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
15994 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
15995 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
15996 Remove unused parameter `fildes'.
15997 * process.c (read_process_output, send_process): Don't pass it.
15999 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
16001 Fix previous change: the library cache is defined in w32.c.
16002 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
16003 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
16005 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
16007 Implement dynamic loading of GnuTLS on Windows.
16009 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
16010 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
16011 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
16014 * gnutls.c (Qgnutls_dll): Define.
16015 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
16016 (gnutls_*): Declare function pointers.
16017 (init_gnutls_functions): New function to initialize function pointers.
16018 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
16019 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
16020 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
16021 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
16022 (emacs_gnutls_write, emacs_gnutls_read)
16023 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
16024 (Fgnutls_available_p): New function.
16025 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
16026 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
16027 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
16029 * image.c: Include w32.h.
16030 (Vimage_type_cache): Delete.

16150 * doprnt.c (doprnt): Don't return value smaller than the buffer
16151 size if the message was truncated. (Bug#8545).

16168 Improve `doprnt' and its usage. (Bug#8545)
16169 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
16170 `format_end'. Remove support for %l as a conversion specifier.
16171 Don't use xrealloc. Improve diagnostics when the %l size modifier
16172 is used. Update the commentary.
16174 * eval.c (verror): Simplify calculation of size_t.
16176 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
16179 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
16181 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
16184 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
16186 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
16187 This makes this file independent of the recent pseudovector change.
16189 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
16191 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
16193 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
16194 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
16195 Remove unused local.
16196 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
16198 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
16199 GCC 4.6.0 optimizes based on type-based alias analysis.
16200 For example, if b is of type struct buffer * and v of type struct
16201 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
16202 != &v->size, and therefore "v->size = 1; b->size = 2; return
16203 v->size;" must therefore return 1. This assumption is incorrect
16204 for Emacs, since it type-puns struct Lisp_Vector * with many other
16205 types. To fix this problem, this patch adds a new type struct
16206 vectorlike_header that documents the constraints on layout of vectors
16207 and pseudovectors, and helps optimizing compilers not get fooled
16208 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
16209 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
16210 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
16212 (XSETPVECTYPE): Rewrite in terms of new macro.
16213 (XSETPVECTYPESIZE): New macro, specifying both type and size.
16214 This is a bit clearer, and further avoids the possibility of
16215 undesirable aliasing.
16216 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
16217 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
16218 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
16219 since Lisp_Subr is a special case (no "next" field).
16220 (ASIZE): Now uses header.size rather than size.
16221 All previous uses of XVECTOR (foo)->size replaced to use this macro,
16222 to avoid the hassle of writing XVECTOR (foo)->header.size.
16223 (struct vectorlike_header): New type.
16224 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
16225 object, to help avoid aliasing.
16226 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
16227 (SUBRP): Likewise, since Lisp_Subr is a special case.
16228 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
16229 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
16230 (struct Lisp_Hash_Table): Combine first two members into a single
16231 struct vectorlike_header member. All uses of "size" and "next" members
16232 changed to be "header.size" and "header.next".
16233 * buffer.h (struct buffer): Likewise.
16234 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
16235 * frame.h (struct frame): Likewise.
16236 * process.h (struct Lisp_Process): Likewise.
16237 * termhooks.h (struct terminal): Likewise.
16238 * window.c (struct save_window_data, struct saved_window): Likewise.
16239 * window.h (struct window): Likewise.
16240 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
16241 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
16242 * buffer.c (init_buffer_once): Likewise.
16243 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
16245 * process.c (Fformat_network_address): Use local var for size,
16248 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
16250 Make the Lisp reader and string-to-float more consistent (Bug#8525)
16251 * data.c (atof): Remove decl; no longer used or needed.
16252 (digit_to_number): Move to lread.c.
16253 (Fstring_to_number): Use new string_to_number function, to be
16254 consistent with how the Lisp reader treats infinities and NaNs.
16255 Do not assume that floating-point numbers represent EMACS_INT
16256 without losing information; this is not true on most 64-bit hosts.
16257 Avoid double-rounding errors, by insisting on integers when
16258 parsing non-base-10 numbers, as the documentation specifies.
16259 * lisp.h (string_to_number): New decl, replacing ...
16260 (isfloat_string): Remove.
16261 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
16262 (read1): Do not accept +. and -. as integers; this
16263 appears to have been a coding error. Similarly, do not accept
16264 strings like +-1e0 as floating point numbers. Do not report
16265 overflow for integer overflows unless the base is not 10 which
16266 means we have no simple and reliable way to continue.
16267 Break out the floating-point parsing into a new
16268 function string_to_number, so that Fstring_to_number parses
16269 floating point numbers consistently with the Lisp reader.
16270 (digit_to_number): Move here from data.c. Make it static inline.
16271 (E_CHAR, EXP_INT): Remove, replacing with ...
16272 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
16273 (string_to_number): New function, replacing isfloat_string.
16274 This function checks for valid syntax and produces the resulting
16275 Lisp float number too. Rework it so that string-to-number
16276 no longer mishandles examples like "1.0e+". Use strtoumax,
16277 so that overflow for non-base-10 numbers is reported only when
16278 there's no portable and simple way to convert to floating point.
16280 * textprop.c (set_text_properties_1): Rewrite for clarity,
16281 and to avoid GCC warning about integer overflow.
16283 * intervals.h (struct interval): Use EMACS_INT for members
16284 where EMACS_UINT might cause problems. See
16285 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
16286 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
16287 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
16289 (offset_intervals): Tell GCC not to worry about length overflow
16290 when negating a negative length.
16292 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
16293 (overrun_check_free): Likewise.
16295 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
16296 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
16299 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
16300 (gnutls_make_error): Rename local to avoid shadowing.
16301 (gnutls_emacs_global_deinit): ifdef out; not used.
16302 (Fgnutls_boot): Use const for pointer to readonly storage.
16303 Comment out unused local. Fix pointer signedness problems.
16305 * lread.c (openp): Don't stuff size_t into an 'int'.
16306 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
16307 about possible signed overflow.
16309 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
16310 (GDK_KEY_g): Don't define if already defined.
16311 (xg_prepare_tooltip): Avoid pointer signedness problem.
16312 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
16314 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
16315 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
16317 * xfns.c (Fx_window_property): Simplify a bit,
16318 to make a bit faster and to avoid GCC 4.6.0 warning.
16319 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
16321 * fns.c (internal_equal): Don't assume size_t fits in int.
16323 * alloc.c (compact_small_strings): Tighten assertion a little.
16325 Replace pEd with more-general pI, and fix some printf arg casts.
16326 * lisp.h (pI): New macro, generalizing old pEd macro to other
16327 conversion specifiers. For example, use "...%"pI"d..." rather
16328 than "...%"pEd"...".
16329 (pEd): Remove. All uses replaced with similar uses of pI.
16330 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
16331 * alloc.c (check_pure_size): Don't overflow by converting size to int.
16332 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
16333 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
16334 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
16335 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
16336 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
16338 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
16339 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
16340 * print.c (safe_debug_print, print_object): Likewise.
16341 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
16343 Use pI instead of if-then-else-abort. Use %p to avoid casts,
16344 avoiding the 0 flag, which is not portable.
16345 * process.c (Fmake_network_process): Use pI to avoid cast.
16346 * region-cache.c (pp_cache): Likewise.
16347 * xdisp.c (decode_mode_spec): Likewise.
16348 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
16349 behavior on 64-bit hosts with printf arg.
16350 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
16351 (x_stop_queuing_selection_requests): Likewise.
16352 (x_get_window_property): Don't truncate byte count to an 'int'
16355 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
16356 here, since it parses constructs like leading '-' and spaces,
16357 which are not wanted; and it overflows with large numbers.
16358 Instead, simply match F[0-9]+, which is what is wanted anyway.
16360 * alloc.c: Remove unportable assumptions about struct layout.
16361 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
16362 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
16363 (allocate_vectorlike, make_pure_vector): Use the new macros,
16364 plus offsetof, to remove unportable assumptions about struct layout.
16365 These assumptions hold on all porting targets that I know of, but
16366 they are not guaranteed, they're easy to remove, and removing them
16367 makes further changes easier.
16369 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
16370 This doesn't fix a bug but makes the code clearer.
16371 (string_overrun_cookie): Now const. Use initializers that
16372 don't formally overflow signed char, to avoid warnings.
16373 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
16374 can cause Emacs to crash when string overrun checking is enabled.
16375 (allocate_buffer): Don't assume sizeof (struct buffer) is a
16376 multiple of sizeof (EMACS_INT); it need not be, if
16377 alignof(EMACS_INT) < sizeof (EMACS_INT).
16378 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
16380 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
16382 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
16384 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
16386 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
16387 supposed to be handshaking. (Bug#8556)
16388 Reported by Paul Eggert <eggert@cs.ucla.edu>.
16390 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
16392 * lisp.h (Qdebug): List symbol.
16393 * eval.c (Qdebug): Restore global linkage.
16394 * keyboard.c (debug-on-event): New variable.
16395 (handle_user_signal): Break into debugger when debug-on-event
16396 matches the current signal symbol.
16398 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
16400 * alloc.c (check_sblock, check_string_bytes)
16401 (check_string_free_list): Convert to standard C.
16403 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
16405 * w32.c (emacs_gnutls_push): Fix typo.
16407 2011-04-25 Eli Zaretskii <eliz@gnu.org>
16409 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
16410 "cast to pointer from integer of different size".
16412 Improve doprnt and its use in verror. (Bug#8545)
16413 * doprnt.c (doprnt): Document the set of format control sequences
16414 supported by the function. Use SAFE_ALLOCA instead of always
16417 * eval.c (verror): Don't limit the buffer size at size_max-1, that
16418 is one byte too soon. Don't use xrealloc; instead xfree and
16421 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
16423 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
16426 * gnutls.c: Renamed global_initialized to
16427 gnutls_global_initialized. Added internals for the
16428 :verify-hostname-error, :verify-error, and :verify-flags
16429 parameters of `gnutls-boot' and documented those parameters in the
16430 docstring. Start callback support.
16431 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
16432 unless a fatal error occurred. Call gnutls_alert_send_appropriate
16433 on error. Return error code.
16434 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
16435 (emacs_gnutls_read): Likewise.
16436 (Fgnutls_boot): Return handshake error code.
16437 (emacs_gnutls_handle_error): New function.
16438 (wsaerror_to_errno): Likewise.
16440 * w32.h (emacs_gnutls_pull): Add prototype.
16441 (emacs_gnutls_push): Likewise.
16443 * w32.c (emacs_gnutls_pull): New function for GnuTLS on Woe32.
16444 (emacs_gnutls_push): Likewise.
16446 2011-04-24 Claudio Bley <claudio.bley@gmail.com> (tiny change)
16448 * process.c (wait_reading_process_output): Check if GnuTLS
16449 buffered some data internally if no FDs are set for TLS
16452 * makefile.w32-in (OBJ2): Add gnutls.$(O).
16453 (LIBS): Link to USER_LIBS.

16761 * process.c (send_process): Adjust to the new signatures of
16762 emacs_write and emacs_gnutls_write. Do not attempt to store

16955 * font.c (font_close_object): Now static.
16956 * font.h (font_close_object): Remove.
16957 * fontset.c (FONTSET_OBJLIST): Remove.
16958 (free_realized_fontset) #if-0 the body, which does nothing.
16959 (face_suitable_for_char_p): #if-0, as it's never called.
16960 * fontset.h (face_suitable_for_char_p): Remove decl.
16961 * xfaces.c (face_at_string_position):
16962 Use FACE_SUITABLE_FOR_ASCII_CHAR_P, not FACE_SUITABLE_FOR_CHAR_P,
16963 since 0 is always ASCII.
16965 * fns.c (weak_hash_tables): Now static.
16967 * fileio.c: Make symbols static if they're not exported.

16986 * editfns.c, lisp.h (get_operating_system_release): Remove.
16987 * process.c (init_process) [DARWIN_OS]: Do it inline, as it is not
16988 worth the hassle of breaking this out.
16990 * xterm.c: Make symbols static if they're not exported.
16991 (x_raise_frame, x_lower_frame, x_wm_set_window_state):

17094 * buffer.c (buffer_count): Remove unused var.

17103 * atimer.h (run_all_atimers): Remove; not exported.
17105 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
17106 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
17107 was inaccessible from Lisp.
17108 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
17109 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
17111 alloc.c: Import and export fewer symbols, and remove unused items.
17112 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
17114 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
17115 it's not optimized away by whole-program optimization.
17116 (message_enable_multibyte, free_misc): Remove.
17117 (catchlist, handlerlist, mark_backtrace):
17118 Declare only if BYTE_MARK_STACK.

17127 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
17128 (mark_backtrace): Define only if BYTE_MARK_STACK.
17129 * xdisp.c (message_enable_multibyte): Now static.
17131 Declare Lisp_Object Q* variables to be 'static' if not exported.
17132 This makes it easier for human readers (and static analyzers)
17133 to see whether these variables are used from other modules.
17134 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
17135 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:

17144 Remove decls of unexported vars.
17145 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
17147 * lisp.h (DEFINE_FUNC): Make sname 'static'.
17149 Make Emacs functions such as Fatom 'static' by default.
17150 This makes it easier for human readers (and static analyzers)
17151 to see whether these functions can be called from other modules.
17152 DEFUN now defines a static function. To make the function external
17153 so that it can be used in other C modules, use the new macro DEFUE.
17154 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
17155 (Finit_image_library):
17156 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
17157 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
17158 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
17159 Remove decls, since these functions are now static.
17160 (Funintern, Fget_internal_run_time): New decls, since these functions
17161 were already external.
17163 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
17164 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

17170 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
17171 Mark functions with DEFUE instead of DEFUN,
17172 if they are used in other modules.
17173 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
17174 decls for now-static functions.
17175 * buffer.h (Fdelete_overlay): Remove decl.
17176 * callproc.c (Fgetenv_internal): Mark as internal.
17177 * composite.c (Fremove_list_of_text_properties): Remove decl.

17181 * doc.c (Fdocumntation_property): New forward static decl.
17182 * eval.c (Ffetch_bytecode): New forward static decl.
17183 (Funintern): Remove extern decl; now in .h file where it belongs.
17184 * fileio.c (Fmake_symbolic_link): New forward static decl.
17185 * image.c (Finit_image_library): New forward static decl.
17186 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
17187 * intervals.h (Fprevious_property_change):
17188 (Fremove_list_of_text_properties): Remove decls.
17189 * keyboard.c (Fthis_command_keys): Remove decl.
17190 (Fcommand_execute): New forward static decl.

17193 * keymap.h (Flookup_key): Remove decl.
17194 * process.c (Fget_process): New forward static decl.
17195 (Fprocess_datagram_address): Mark as internal.

17206 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
17208 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
17211 2011-04-13 Eli Zaretskii <eliz@gnu.org>
17213 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
17214 when at ZV. (Bug#8487)
17216 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
17218 * charset.c (Fclear_charset_maps): Use xfree instead of free.
17220 * keyboard.c (parse_tool_bar_item): Likewise.
17221 * sound.c (sound_cleanup, alsa_close): Likewise.
17222 * termcap.c (tgetent): Likewise.
17223 * xfns.c (x_default_font_parameter): Likewise.
17224 * xsettings.c (read_and_apply_settings): Likewise.
17226 * alloc.c (overrun_check_malloc, overrun_check_realloc)
17227 (overrun_check_free): Protoize.
17229 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
17231 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
17232 since callers should never pass a negative size.
17233 Change the signature to match that of plain 'read' and 'write'; see
17234 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
17235 * lisp.h: Update prototypes of emacs_write and emacs_read.
17237 2011-04-11 Eli Zaretskii <eliz@gnu.org>
17239 * xdisp.c (redisplay_window): Don't try to determine the character
17240 position of the scroll margin if the window start point w->startp
17241 is outside the buffer's accessible region. (Bug#8468)
17243 2011-04-10 Eli Zaretskii <eliz@gnu.org>
17245 Fix write-region and its subroutines for buffers > 2GB.
17246 * fileio.c (a_write, e_write): Modify declaration of arguments and
17247 local variables to support buffers larger than 2GB.
17248 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
17250 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
17251 argument, local variables, and return value.
17253 * lisp.h: Update prototypes of emacs_write and emacs_read.
17255 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
17257 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
17259 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
17261 Fix more problems found by GCC 4.6.0's static checks.
17263 * xdisp.c (vmessage): Use a better test for character truncation.
17265 * charset.c (load_charset_map): <, not <=, for optimization,
17266 and to avoid potential problems with integer overflow.
17267 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
17268 * casetab.c (set_identity, shuffle): Likewise.
17269 * editfns.c (Fformat): Likewise.
17270 * syntax.c (skip_chars): Likewise.
17272 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
17273 This also lets GCC 4.6.0 generate slightly better loop code.
17275 * callint.c (Fcall_interactively): <, not <=, for optimization.
17276 (Fcall_interactively): Count the number of arguments produced,
17277 not the number of arguments given. This is simpler and lets GCC
17278 4.6.0 generate slightly better code.
17280 * ftfont.c: Distingish more carefully between FcChar8 and char.
17281 The previous code passed unsigned char * to a functions like
17282 strlen and xstrcasecmp that expect char *, which does not
17283 conform to the C standard.
17284 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
17285 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
17286 char * when the C standard requires it.
17288 * keyboard.c (read_char): Remove unused var.
17290 * eval.c: Port to Windows vsnprintf (Bug#8435).
17291 Include <limits.h>.
17292 (SIZE_MAX): Define if the headers do not.
17293 (verror): Do not give up if vsnprintf returns a negative count.
17294 Instead, grow the buffer. This ports to Windows vsnprintf, which
17295 does not conform to C99. Problem reported by Eli Zaretskii.
17296 Also, simplify the allocation scheme, by avoiding the need for
17297 calling realloc, and removing the ALLOCATED variable.
17299 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
17301 Remove invocations of doprnt, as Emacs now uses vsnprintf.
17302 But keep the doprint source code for now, as we might revamp it
17303 and use it again (Bug#8435).
17304 * lisp.h (doprnt): Remove.
17305 * Makefile.in (base_obj): Remove doprnt.o.
17306 * deps.mk (doprnt.o): Remove.
17308 error: Print 32- and 64-bit integers portably (Bug#8435).
17309 Without this change, on typical 64-bit hosts error ("...%d...", N)
17310 was used to print both 32- and 64-bit integers N, which relied on
17311 undefined behavior.
17312 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
17313 * lisp.h (error, verror): Mark as printf-like functions.
17314 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
17315 Report overflow in size calculations when allocating printf buffer.
17316 Do not truncate output string at its first null byte.
17317 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
17318 Truncate the output at a character boundary, since vsnprintf does not
17320 * charset.c (check_iso_charset_parameter): Convert internal
17321 character to string before calling 'error', since %c now has the
17323 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
17324 overflow when computing char to be passed to 'error'. Do not
17325 pass Lisp_Object to 'error'; pass the integer instead.
17326 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
17327 formatted with plain %d.
17329 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
17331 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
17333 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
17335 * xterm.c (x_catch_errors): Remove duplicate declaration.
17337 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
17339 * xdisp.c, lisp.h (message_nolog): Remove; unused.
17341 2011-04-10 Jim Meyering <meyering@redhat.com>
17343 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
17344 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
17345 return ssize_t not "int", and use size_t as the buffer length.
17346 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
17347 * gnutls.h: Update declarations.
17348 * process.c (read_process_output): Use ssize_t, to match.
17349 (send_process): Likewise.
17351 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
17353 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
17355 2011-04-09 Chong Yidong <cyd@stupidchicken.com>

17358 Use unsigned char, to match FcChar8 type definition.
17360 * xterm.c (handle_one_xevent):
17361 * xmenu.c (create_and_show_popup_menu):
17362 * xselect.c (x_decline_selection_request)

17365 2011-04-09 Eli Zaretskii <eliz@gnu.org>
17367 Fix some uses of `int' instead of EMACS_INT.
17368 * search.c (string_match_1, fast_string_match)
17369 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
17370 (scan_buffer, find_next_newline_no_quit)
17371 (find_before_next_newline, search_command, Freplace_match)

17461 * eval.c (Fsignal): Remove excess argument to 'fatal'.
17463 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
17464 This avoids several warnings with gcc -Wstrict-overflow.
17465 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
17466 directly, rather than having caller test rule sign. This avoids
17467 some unnecessary tests.
17468 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
17469 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
17470 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
17472 * xfont.c (xfont_text_extents): Remove var that was set but not used.
17473 (xfont_open): Avoid unnecessary tests.
17475 * composite.c (composition_gstring_put_cache): Use unsigned integer.
17477 * composite.h, composite.c (composition_gstring_put_cache):
17478 Use EMACS_INT, not int, for length.
17480 * composite.h (COMPOSITION_DECODE_REFS): New macro,
17481 breaking out part of COMPOSITION_DECODE_RULE.
17482 (COMPOSITION_DECODE_RULE): Use it.
17483 * composite.c (get_composition_id): Remove unused local vars,
17484 by using the new macro.
17486 * textprop.c (set_text_properties_1): Change while to do-while,
17487 since the condition is always true at first.
17489 * intervals.c (graft_intervals_into_buffer): Mark var as used.
17490 (interval_deletion_adjustment): Return unsigned value.
17493 * process.c (list_processes_1, create_pty, read_process_output):
17494 (exec_sentinel): Remove vars that were set but not used.
17495 (create_pty): Remove unnecessary "volatile"s.

17509 * print.c (print_error_message): Avoid int overflow.
17511 * font.c (font_list_entities): Redo for clarity,
17512 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
17514 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
17515 (font_score): Avoid potential overflow in diff calculation.
17517 * fns.c (substring_both): Remove var that is set but not used.
17518 (sxhash): Redo loop for clarity and to avoid wraparound warning.
17520 * eval.c (funcall_lambda): Rename local to avoid shadowing.
17522 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
17523 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
17524 can always succeed if overflow has undefined behavior.
17526 * search.c (boyer_moore, wordify): Remove vars set but not used.
17527 (wordify): Omit three unnecessary tests.
17529 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.

17532 * casefiddle.c (casify_region): Remove var that is set but not used.
17534 * dired.c (file_name_completion): Remove var that is set but not used.
17536 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
17538 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
17539 (Finsert_file_contents): Remove unnecessary code checking fd.
17541 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
17542 Check for integer overflow on size calculations.
17544 * buffer.c (Fprevious_overlay_change): Remove var that is set
17547 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
17548 Remove vars that are set but not used.
17549 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
17550 (timer_check_2): Mark vars as initialized.
17552 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
17554 * image.c (lookup_image): Remove var that is set but not used.
17555 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
17557 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
17558 that are set but not used.
17560 * xfns.c (make_invisible_cursor): Don't return garbage
17561 if XCreateBitmapFromData fails (Bug#8410).
17563 * xselect.c (x_get_local_selection, x_handle_property_notify):
17564 Remove vars that are set but not used.
17566 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
17567 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
17569 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
17570 Remove var that is set but not used.
17571 (scroll_bar_windows_size): Now size_t, not int.
17572 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
17573 Check for overflow.
17575 * xfaces.c (realize_named_face): Remove vars that are set but not used.
17576 (map_tty_color) [!defined MSDOS]: Likewise.
17578 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
17580 * coding.c: Remove vars that are set but not used.
17581 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
17582 All callers changed.
17583 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
17584 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
17585 (decode_coding_charset): Remove vars that are set but not used.
17587 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
17588 that is set but not used.
17590 * print.c (print_object): Remove var that is set but not used.
17592 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
17593 The gnulib version avoids calling malloc in the usual case,
17594 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
17595 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
17596 * filelock.c (current_lock_owner): Likewise.
17597 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
17598 * sysdep.c: Include allocator.h, careadlinkat.h.
17599 (emacs_no_realloc_allocator): New static constant.
17600 (emacs_readlink): New function.
17601 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
17602 ../lib/careadlinkat.h.
17604 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
17606 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
17607 first non-nil return value).

17611 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
17612 if not defined (Bug#8403).
17614 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
17616 * xdisp.c (display_count_lines): Remove parameter `start',
17617 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
17618 (get_char_face_and_encoding): Remove parameter `multibyte_p',
17619 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

17621 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
17622 and thereabouts. All callers changed.
17623 (get_per_char_metric): Remove parameter `f', unused since
17624 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
17626 2011-04-02 Jim Meyering <meyering@redhat.com>
17628 do not dereference NULL upon failed strdup
17629 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
17630 (ns_get_family): Likewise.
17632 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
17634 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
17636 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
17638 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
17641 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
17643 Add lexical binding.
17645 * window.c (Ftemp_output_buffer_show): New fun.
17646 (Fsave_window_excursion):
17647 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
17649 * lread.c (lisp_file_lexically_bound_p): New function.
17650 (Fload): Bind Qlexical_binding.
17651 (readevalloop): Remove `evalfun' arg.
17652 Bind Qinternal_interpreter_environment.
17653 (Feval_buffer): Bind Qlexical_binding.
17654 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
17656 (syms_of_lread): Declare `lexical-binding'.
17658 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
17660 * keyboard.c (eval_dyn): New fun.
17661 (menu_item_eval_property): Use it.
17663 * image.c (parse_image_spec): Use Ffunctionp.
17665 * fns.c (concat, mapcar1): Accept byte-code-functions.
17667 * eval.c (Fsetq): Handle lexical vars.
17668 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
17669 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
17670 (FletX, Flet): Obey lexical binding.
17671 (Fcommandp): Handle closures.
17672 (Feval): New `lexical' arg.
17673 (eval_sub): New function extracted from Feval. Use it almost
17674 everywhere where Feval was used. Look up vars in lexical env.
17676 (Ffunctionp): Move from subr.el.
17677 (Ffuncall): Handle closures.
17678 (apply_lambda): Remove `eval_flags'.
17679 (funcall_lambda): Handle closures and new byte-code-functions.
17680 (Fspecial_variable_p): New function.
17681 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
17682 but without exporting it to Lisp.
17684 * doc.c (Fdocumentation, store_function_docstring):
17685 * data.c (Finteractive_form): Handle closures.
17687 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
17690 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
17692 (exec_byte_code): New function extracted from Fbyte_code to handle new
17693 calling convention for byte-code-functions. Add new byte-codes.
17695 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
17697 * alloc.c (Fmake_symbol): Init new `declared_special' field.
17699 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
17701 * xdisp.c (redisplay_internal): Fix prototype.
17703 2011-03-31 Eli Zaretskii <eliz@gnu.org>
17705 * xdisp.c (SCROLL_LIMIT): New macro.
17706 (try_scrolling): Use it when setting scroll_limit.
17707 Limit scrolling to 100 screen lines.
17708 (redisplay_window): Even when falling back on "recentering",
17709 position point in the window according to scroll-conservatively,
17710 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
17712 (try_scrolling): When point is above the window, allow searching
17713 as far as scroll_max, or one screenful, to compute vertical
17714 distance from PT to the scroll margin position. This prevents
17715 try_scrolling from unnecessarily failing when
17716 scroll-conservatively is set to a value slightly larger than the
17717 window height. Clean up the case of PT below the margin at bottom
17718 of window: scroll_max can no longer be INT_MAX. When aggressive
17719 scrolling is in use, don't let point enter the opposite scroll
17720 margin as result of the scroll.
17721 (syms_of_xdisp) <scroll-conservatively>: Document the
17722 threshold of 100 lines for never-recentering scrolling.
17724 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
17726 * dispextern.h (move_it_by_lines):
17727 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
17728 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
17729 (message_log_check_duplicate): Remove parameters `prev_bol' and
17730 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
17731 (redisplay_internal): Remove parameter `preserve_echo_area',
17732 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
17734 * indent.c (Fvertical_motion):
17735 * window.c (window_scroll_pixel_based, Frecenter):
17736 Don't pass `need_y_p' to `move_it_by_lines'.
17738 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
17740 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
17741 steal a few bits to be more compact.
17742 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
17743 Remove unneeded casts.
17745 * bytecode.c (Fbyte_code): CAR and CDR can GC.
17747 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
17749 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
17750 binding" message (bug#7967).
17752 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
17754 Fix more problems found by GCC 4.6.0's static checks.
17756 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
17757 Remove unused local var.
17759 * editfns.c (Fmessage_box): Remove unused local var.
17761 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
17762 (note_mode_line_or_margin_highlight, note_mouse_highlight):
17763 Omit unused local vars.
17764 * window.c (shrink_windows): Omit unused local var.
17765 * menu.c (digest_single_submenu): Omit unused local var.
17766 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
17767 Omit unused local var.
17769 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
17770 Don't assume string length fits in int.
17771 (keyremap_step, read_key_sequence): Use size_t for sizes.
17772 (read_key_sequence): Don't check last_real_key_start redundantly.
17774 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
17775 instead of alloca (Bug#8344).
17777 * eval.c (Fbacktrace): Don't assume nargs fits in int.
17778 (Fbacktrace_frame): Don't assume nframes fits in int.
17780 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
17782 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
17785 * term.c (produce_glyphless_glyph): Remove unnecessary test.
17787 * cm.c (calccost): Turn while-do into do-while, for clarity.
17789 * keyboard.c (syms_of_keyboard): Use the same style as later
17790 in this function when indexing through an array. This also
17791 works around GCC bug 48267.
17793 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
17795 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
17797 * chartab.c (sub_char_table_ref_and_range): Redo for slight
17798 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
17800 * keyboard.c, keyboard.h (num_input_events): Now size_t.
17801 This avoids undefined behavior on integer overflow, and is a bit
17802 more convenient anyway since it is compared to a size_t variable.
17804 Variadic C functions now count arguments with size_t, not int.
17805 This avoids an unnecessary limitation on 64-bit machines, which

18029 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
18031 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
18032 unconditionally since it does the check itself.
18034 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
18036 Fix more problems found by GCC 4.5.2's static checks.
18038 * coding.c (encode_coding_raw_text): Avoid unnecessary test
18039 the first time through the loop, since we know p0 < p1 then.
18040 This also avoids a gcc -Wstrict-overflow warning.
18042 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
18043 leading to a memory leak, possible in functions like
18044 load_charset_map_from_file that can allocate an unbounded number
18045 of objects (Bug#8318).
18047 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
18048 that could (at least in theory) be that large.
18050 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
18051 This is less likely to overflow, and avoids undefined behavior if
18052 overflow does occur. All callers changed. Use strtoul to scan
18053 for the unsigned long integer.
18054 (pint2hrstr): Simplify and tune code slightly.
18055 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

18070 * process.c (Fmake_network_process): Use socklen_t, not int,
18071 where POSIX says socklen_t is required in portable programs.
18072 This fixes a porting bug on hosts like 64-bit HP-UX, where
18073 socklen_t is wider than int (Bug#8277).
18074 (Fmake_network_process, server_accept_connection):
18075 (wait_reading_process_output, read_process_output):
18078 * process.c: Rename or move locals to avoid shadowing.

18088 Make tparam.h and terminfo.c consistent.
18089 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
18090 Include tparam.h instead, since it declares them.
18091 * cm.h (PC): Remove extern decl; tparam.h now does this.
18092 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
18093 * terminfo.c: Include tparam.h, to check interfaces.
18094 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
18095 (tparam): Adjust signature to match interface in tparam.h;
18096 this removes some undefined behavior. Check that outstring and len
18097 are zero, which they always are with Emacs.
18098 * tparam.h (PC, BC, UP): New extern decls.
18100 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
18101 (xftfont_open): Rename locals to avoid shadowing.

18119 (composition_update_it): Mark var as initialized.
18120 (find_automatic_composition): Mark vars as initialized,
18121 with a FIXME (Bug#8290).

18127 (BUF_DEC_POS): Be more systematic about renaming local temporaries
18128 to avoid shadowing.

18140 Fix pointer signedness.
18141 (alsa_choose_format): Remove unused local var.
18142 (wav_play): Initialize a variable to 0, to prevent undefined
18143 behavior (Bug#8278).
18145 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
18147 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
18149 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
18150 clobbering (Bug#8298).
18151 * sysdep.c (sys_subshell): Likewise.
18152 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
18154 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
18155 This should get cleaned up, so that child_setup has the
18156 same signature on all platforms.
18158 * callproc.c (call_process_cleanup): Now static.
18159 (relocate_fd): Rename locals to avoid shadowing.
18161 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
18163 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
18164 not to be necessary, and produces flickering.
18166 2011-03-20 Glenn Morris <rgm@gnu.org>
18168 * config.in: Remove file.
18170 2011-03-20 Juanma Barranquero <lekktu@gmail.com>

18214 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
18215 Define only if needed.
18217 * unexelf.c (unexec): Name an expression,
18218 to avoid gcc -Wbad-function-cast warning.
18219 Use a different way to cause a compilation error if anyone uses
18220 n rather than nn, a way that does not involve shadowing.
18221 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
18223 * deps.mk (unexalpha.o): Remove; unused.

18289 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
18290 some of which prompt warnings from gcc -Wbad-function-cast.
18291 (Fformat_time_string, Fencode_time, Finsert_char):

18320 (Fmemory_limit): Cast sbrk's returned value to char *.
18322 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this

18330 to use the following functions instead of these macros.
18331 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
18332 EMACS_INT, since callers assume the returned value fits in int.
18333 (upcase1): Likewise, for UPCASE_TABLE.
18334 (uppercasep, lowercasep, upcase): New static inline functions.
18335 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

18345 (regex_compile, re_match_2_internal): Mark locals as initialized.
18346 (RETALLOC_IF): Define only if needed.
18347 (WORDCHAR_P): Likewise. This one is never needed, but is used
18348 only in a comment talking about a compiler bug, so put inside
18349 the #if 0 of that comment.
18350 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
18351 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

18377 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
18378 New macros, so that the caller can use some names other than
18379 gcpro1, gcpro2, etc.
18380 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
18382 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
18383 argument, for consistency with GCPRO2_VAR, etc: it is now the
18384 prefix of the variable, not the variable itself. All uses
18386 * dired.c (directory_files_internal, file_name_completion):
18387 Rename locals to avoid shadowing.
18389 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
18390 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
18391 dired.c's scmp function, had undefined behavior.
18392 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
18393 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
18394 * buffer.h: ... to here, because these macros use current_buffer,
18395 and the new implementation with inline functions needs to have
18396 current_buffer in scope now, rather than later when the macros
18398 (downcase, upcase1): New static inline functions.
18399 (DOWNCASE, UPCASE1): Reimplement using these functions.
18400 This avoids undefined behavior in expressions like
18401 DOWNCASE (x) == DOWNCASE (y), which previously suffered
18402 from race conditions in accessing the global variables
18403 case_temp1 and case_temp2.
18404 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
18405 * lisp.h (case_temp1, case_temp2): Remove their decls.
18406 * character.h (ASCII_CHAR_P): Move from here ...
18407 * lisp.h: ... to here, so that the inline functions mentioned
18408 above can use them.

18415 (file_name_as_directory): Use const pointers when appropriate.
18416 (Fexpand_file_name): Likewise. In particular, newdir might
18417 point at constant storage, so make it a const pointer.

18421 (Fset_file_times, Finsert_file_contents, auto_save_error):

18426 to avoid shadowing.
18428 * marker.c (bytepos_to_charpos): Remove; unused.
18430 * lisp.h (verify_bytepos, count_markers): New decls,
18431 so that gcc does not warn that these functions aren't declared.
18433 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
18434 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
18435 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
18436 (copy_text): Remove unused local var.

18441 * buffer.c (fix_overlays_before): Mark locals as initialized.
18442 (fix_start_end_in_overlays): Likewise. This function should be
18443 simplified by using pointers-to-pointers, but that's a different

18446 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
18447 (report_overlay_modification): Rename locals to avoid shadowing.

18450 Fix pointer signedness issue.
18451 (sys_subshell): Mark local as volatile if checking for lint,
18452 to suppress a gcc -Wclobbered warning that does not seem to be right.
18453 (MAXPATHLEN): Define only if needed.
18455 * process.c (serial_open, serial_configure): Move decls from here ...
18456 * systty.h: ... to here, so that they can be checked.
18458 * fns.c (get_random, seed_random): Move extern decls from here ...
18459 * lisp.h: ... to here, so that they can be checked.
18461 * sysdep.c (reset_io): Now static.

18620 For example, without this patch (encode-time 0 0 0 1 1
18621 1152921504606846976) returns the obviously-bogus value (-948597
18622 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
18623 reports time overflow. See
