26 Fix some stat-related races.
27 * fileio.c (Fwrite_region): Avoid race condition if a file is
28 removed or renamed by some other process immediately after Emacs
29 writes it but before Emacs stats it. Do not assume that stat (or

157 Use bool for boolean.
158 * keyboard.c (timers_run, swallow_events)
159 (detect_input_pending_run_timers):
160 * process.c (wait_reading_process_output):
161 Use unsigned for counter where wraparound-on-overflow is desired,
162 since unsigned is guaranteed to have that behavior and signed is not.
163 (read_char): Use ptrdiff_t for string length.
164 (get_input_pending): Remove first argument, since it was always
165 the same pointer-to-int (now pointer-to-boolean) &input_pending,
166 and behave as if it had that value. Return new value of
167 input_pending. All callers changed.
168 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
169 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's

189 Clean out old termopts cruft.
190 * termopts.h (flow_control, meta_key): Remove unused decls.
191 * dispnew.c, indent.c, nsterm.m, term.c, xsettings.c, xsmfns.c:
192 Don't include termopts.h.
194 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>
196 * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers.
198 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
200 * commands.h (immediate_quit): Remove duplicate decl.
202 2012-10-09 Jan Djärv <jan.h.d@swipnet.se>

207 (syms_of_nsfont): Remove initialization of Vfonts_in_cache
209 2012-10-09 Eli Zaretskii <eliz@gnu.org>
211 * w32fns.c (w32_last_error): Change the return value to DWORD, to
212 match what GetLastError returns. Explain why the function is
215 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
216 'is_tooltip_frame', to avoid confusion with its global namesake.
218 2012-10-08 Daniel Colascione <dancol@dancol.org>
220 * xdisp.c (start_hourglass): Call w32_note_current_window when
221 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
222 build that caused Emacs to display the hourglass cursor forever.
224 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
225 which is broken under remote desktop, calculate the number of
226 colors available for a display based on the display's number of
227 planes and number of bits per pixel per plane. (bug#10397).
229 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
231 * nsfont.m (Vfonts_in_cache): New variable.
232 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
233 are used. Add cached fonts to Vfonts_in_cache.
234 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
236 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
238 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
240 (FONT_H): Define after FRAME_H.
241 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
244 * w32term.c: Remove leftover declaration of keyboard_codepage.
246 2012-10-08 Eli Zaretskii <eliz@gnu.org>
248 * makefile.w32-in (FONT_H): Add $(FRAME_H).
249 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
250 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
251 (GLOBAL_SOURCES): Add cygw32.c.
252 ($(BLD)/unexw32.$(O)):
254 ($(BLD)/w32console.$(O)):
255 ($(BLD)/w32fns.$(O)):
256 ($(BLD)/w32heap.$(O)):
257 ($(BLD)/w32menu.$(O)):
258 ($(BLD)/w32proc.$(O)): Add w32common.h.
260 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
262 (x_to_w32_color): Don't modify the argument, modify a copy instead.
264 2012-10-08 Daniel Colascione <dancol@dancol.org>
266 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
267 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
268 accidental message numbering hole. Change other messages to
271 * w32select.h (HAVE_W32SELECT): Remove.
273 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
274 w32common.h instead of w32heap.h
276 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)

284 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
285 (w32_minor_version, w32_build_number, w32_subtype): Remove
286 duplicate definitions.
288 * w32fns.c: Include w32common.h; include w32heap.h only in
291 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
292 Use `report_file_error' instead of `error' in order to better
293 inform users of what went wrong. Increase NTGUI_UNICODE file
294 dialog box file name length to 32k, the maximum allowed by the NT
297 * w32common.h: New file.
298 (ROUND_UP, ROUND_DOWN, get_page_size)
299 (get_allocation_unit, get_processor_type, get_w32_major_version)
300 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
301 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
302 (OS_NT, os_subtype, cache_system_info): Move here.
304 * unexw32.c, unexcw.c: Include w32common.h.
306 * emacs.c (main): Use (defined (WINDOWSNT) || defined
307 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
308 to call syms_of_w32select.
310 * cygw32.h: Remove obsolete EXFUN declarations.
312 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
314 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
315 of w32inevt.o from SOME_MACHINE_OBJECTS.
317 2012-10-08 Daniel Colascione <dancol@dancol.org>
319 * image.c: Permanent fix for JPEG compilation issue --- limit
320 jpeglib `boolean' redefinition to Cygwin builds.
322 2012-10-08 Eli Zaretskii <eliz@gnu.org>
324 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
326 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
329 2012-10-08 Daniel Colascione <dancol@dancol.org>
331 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
332 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
333 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
334 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
335 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
336 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
337 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
338 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
339 now a supported configuration.
341 * Makefile.in: consolidate image variables into LIBIMAGE; add
342 W32_OBJ and W32_LIBS. Compile new files.
345 (_DebPrint) declare tracing facility for W32 debugging. We need
346 to unify tracing later.
348 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
349 unconditional use of W32 Unicode functions. Cygwin runs only on
350 100% Unicode operating systems.
352 * cygw32.c: New file. Define Cygwin-specific facilities.
353 (Fcygwin_convert_path_to_windows)
354 (Fcygwin_convert_path_from_windows): New user functions for
355 accessing Cygwin path-munging routines.
357 * cygw32.h: New file.
358 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
359 UTF-16LE strings temporarily inside non-Lisp-visible string
362 (w32_strerror): Just what it says on the tin.
364 * emacs.c: Make the NS fork-then-exec code for daemon-launching
365 also run for Cygwin; both systems have the same problem with using
366 GUI facilities in a forked child. Also call syms_of_cygw32,
367 syms_of_w32select in correct places.
369 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
370 needs fork-then-exec for daemon launching.
372 * font.h: Include frame.h.
374 * image.c: Use the image library cache machinery only when we're
375 compiling for native WINDOWSNT; Cygwin can use shared libraries
376 like any other Unixlike system.
378 * keyboard.c: Clarify a comment regarding the input loop.
380 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
381 functions directly instead of trying to detect at runtime that our
382 host operating system supports them. We make this change for two
383 reasons: Cygwin lacks support for the multibyte character
384 conversion functions used by the legacy menu code, and Cygwin
385 never needs to rely on non-Unicode APIs.
387 * unexw32.c (hinst): Declare extern.
389 * w32.c: Change header order;
390 (w32_strerror): Move to w32fns.c because we need it for
391 non-WINDOWSNT builds.
393 * w32.h: Add #error macro to make sure we don't include w32.h for
394 Cygwin builds. Remove w32select declarations.
396 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
397 w32fns.c. w32console.c is WINDOWSNT-only.
399 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
400 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
402 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
403 (w32_major_version, w32_minor_version, w32_build_number)
404 (os_subtype, sound_type): Define here
405 (w32_defined_color): Make color parameter const for consistency
406 with other _defined_color functions.
407 (w32_createwindow): Unconditionally call w32_init_class instead of
408 doing so only when hprevinst is non-NULL. Plumbing hprevinst
409 through the code is complex and unnecessary because class
410 registration is practically free.
411 (w32_name_of_message): New EMACSDEBUG-only function.
412 (Fset_message_beep): Move here
413 (Fx_open_connection): Require that the display name for Windows be
414 "w32" for consistency, emacsclient disambiguation, and maybe, one
415 day, multi-window-system support.
416 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
417 Cygwin files for W32 GUI facilities, since these clearly don't
420 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
421 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
422 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
423 (w32_last_error): Remove.
425 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
427 * w32heap.c (syspage_mask): Declare here.
428 (cache_system_info): Remove.
430 * w32inevt.c (faked_key): Define globally, not statically.
431 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
432 (w32_console_toggle_lock_key): Move to w32fns.c.
434 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
436 * w32proc.c (_DebPrint): Move to w32fns.c.
437 * w32select.c: Include string.h, stdio.h for Cygwin.
438 * w32select.h: New File.
440 * w32term.c: Include io.h for non-CYGWIN builds; needed for
442 (w32_message_fd): New variable. Under Cygwin, holds the file
443 descriptor the system used to tell us about pending thread
446 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
447 that prevented compilation under non-WINDOWSNT systems.
449 (w32_initialize): Open /dev/windows and assign it to
450 w32_message_fd. Provide w32 feature.
452 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
453 (WM_EMACS_INPUT_READY): add.
454 (prepend_msg, w32_message_fd): Declare globally.
457 (keyboard_handle): Use only when WINDOWSNT.
458 (notify_msg_ready): New function. Posts a message to the main
459 thread's message queue under CYGWIN, which wakes up the main
460 thread from select(2) by making the /dev/windows file descriptor
461 ready. Under WINDOWSNT, it sets an event the same way the old
464 (post, prepend_msg): Actually call notify_msg_ready instead of
465 setting the input event directly.
467 2012-10-07 Eli Zaretskii <eliz@gnu.org>
469 * ralloc.c (relinquish): If a heap is ready to be relinquished,
470 but it still has blocs in it, don't return it to the system,
471 instead of aborting. (Bug#12402)
473 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
475 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
477 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
478 MAC_OS_X_VERSION_10_6.
479 (syms_of_nsterm): Remove comment about Panther and above for

486 MAC_OS_X_VERSION_10_4.
488 * nsmenu.m (fillWithWidgetValue:): Remove code for <
489 MAC_OS_X_VERSION_10_2.
491 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
493 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
494 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
496 * nsterm.m (ns_in_resize): Remove (Bug#12479).
497 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
498 (ns_clear_frame, sendEvent, windowDidResize, drawRect:): Remove
500 (ns_clear_frame_area): Remove resize handle code.

506 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
508 Improve sys_siglist detection.
509 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
510 defined as a macro, as is done in Solaris.
511 (sys_siglist_entries): New macro.
512 (save_strsignal): Use it.
513 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
514 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
516 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
518 * nsfns.m (Fx_create_frame): Call x_default_parameter with
519 fullscreen/Fullscreen.
521 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
524 * nsterm.m (x_make_frame_visible): Check for fullscreen.

530 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
531 error in drawing background.
532 (toggleFullScreen:): Remove comment. Rearrange calls.

535 (canBecomeMainWindow): New function.
537 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
539 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
541 2012-10-05 Eli Zaretskii <eliz@gnu.org>
543 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
545 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
546 that time stamps of directories could also be changed. Don't
547 request the too broad GENERIC_WRITE, only the more restrictive
548 FILE_WRITE_ATTRIBUTES access rights.
550 * fileio.c (Fset_file_times): Special-case ignoring errors for
551 directories only on MSDOS, not on MS-Windows.
553 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
555 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
557 2012-10-04 Eli Zaretskii <eliz@gnu.org>

560 see whether CreateFile failed.
562 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
564 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
565 to avoid similar races.
566 * keyboard.c (pending_signals): Now bool, not int.
568 Port timers to OpenBSD, plus check for timer failures.
569 OpenBSD problem reported by Han Boetes.
570 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
572 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
573 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
574 like OpenBSD, which has timer_settime but does not declare it.
575 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
576 whether to use itimerspec-related primitives. All uses of
577 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
579 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
581 * profiler.c (handle_profiler_signal): Fix a malloc race
582 that caused Emacs to hang on Fedora 17 when profiling Lisp.
584 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
586 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
588 2012-10-02 Eli Zaretskii <eliz@gnu.org>

591 consistent with the change in return value of 'safe_strsignal'.
593 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
595 Prefer plain 'static' to 'static inline' (Bug#12541).
596 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
597 (bidi_set_sor_type, bidi_push_embedding_level)
598 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)

603 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
604 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
605 Now 'static', not 'static inline'.
607 Count overruns when profiling; change units to ns.
608 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
609 Give extra weight to samples after overruns, to attempt to count
610 the time more accurately.
611 (setup_cpu_timer): Change sampling interval units from ms to ns, since
612 the underlying primitives nominally do ns.
613 (Fprofiler_cpu_start): Document the change. Mention that
614 the sampling intervals are only approximate.
616 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
618 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
620 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
621 case for the special 0 coding-system.
623 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
624 (Fmake_overlay): Remove redundant tests.
625 (fix_start_end_in_overlays): Remove redundant recentering.
627 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
629 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
632 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
634 Fix a malloc race condition involving strsignal.
635 A signal can arrive in the middle of a malloc, and Emacs's signal
636 handler can invoke strsignal, which can invoke malloc, which is
637 not portable. This race condition bug makes Emacs hang on GNU/Linux.
638 Fix it by altering the signal handler so that it does not invoke
640 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
641 * process.c (status_message): Use const pointer, in case strsignal
642 is #defined to safe_strsignal.
643 * sysdep.c (sys_siglist, init_signals): Always define and
644 initialize a substitute sys_siglist if the system does not define
645 one, even if HAVE_STRSIGNAL.
646 (safe_strsignal): Rename from strsignal. Always define,
647 using sys_siglist. Return a const pointer.
648 * syssignal.h (safe_strsignal): New decl.
649 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
651 2012-10-01 Eli Zaretskii <eliz@gnu.org>
653 * w32proc.c (timer_loop): Fix code that waits for timer
654 expiration, to avoid high CPU usage.
656 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
658 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
659 (sweep_weak_table): Remove redundant prototypes.
661 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
663 * emacs.c: Move the inclusion of TERM_HEADER after including
664 windows.h on WINDOWSNT. This avoids compilation problems with
667 2012-10-01 Eli Zaretskii <eliz@gnu.org>
669 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
670 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
671 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
672 as the previous version used 'void *'.
674 * ralloc.c (ROUNDUP): Fix last change.
675 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
678 * w32proc.c <disable_itimers>: New static flag.
679 (init_timers): Initialize it to zero, after creating the critical
680 sections used by the timer threads.
681 (term_timers): Set to 1 before deleting the critical sections.
682 (getitimer, setitimer): If disable_itimers is non-zero, return an
683 error indication without doing anything. Reported by Fabrice
684 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
685 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
687 [!HAVE_SETITIMER]: Behave as the previous version that didn't
690 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
691 term_ntproc after all the other bookkeeping, to get timers working
694 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
696 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
697 Suggested by Juri Linkov in
698 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
700 Prefer plain 'static' to 'static inline' (Bug#12541).
701 With static functions, modern compilers inline pretty well by
702 themselves; advice from programmers often hurts as much as it helps.
703 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
704 this change shrinks the text size of the Emacs executable by 1.1%
705 without affecting CPU significantly in my benchmark.

968 * fns.c (Frandom): Doc fix.
970 2012-09-30 Martin Rudalics <rudalics@gmx.at>
972 * window.c (Vwindow_combination_limit): New default value.
973 (Qwindow_size): New symbol replacing Qtemp_buffer_resize.
975 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
977 * syssignal.h (PROFILER_CPU_SUPPORT): Don't define if PROFILING.
978 Suggested by Eli Zaretskii in
979 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00811.html>.
981 2012-09-30 Eli Zaretskii <eliz@gnu.org>
983 * profiler.c (Fprofiler_cpu_stop): Use timer_settime only if
984 HAVE_TIMER_SETTIME is defined.
986 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
988 Profiler improvements: more-accurate timers, overflow checks.
989 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
990 signal.h, setjmp.h. Include systime.h instead.
991 (saturated_add): New function.
992 (record_backtrace, current_sample_interval): Use EMACS_INT, not size_t.
993 (record_backtrace, handle_profiler_signal): Saturate on fixnum overflow.
994 (profiler_timer, profiler_timer_ok) [HAVE_TIMER_SETTIME]:
996 (enum profiler_cpu_running): New enum.
997 (profiler_cpu_running): Now of that enum type, not bool.
998 All uses changed to store the new value.
999 (handle_profiler_signal): Rename from sigprof_handler_1,
1000 for consistency with other handlers. Do not check whether
1001 cpu_log is a hash-table if garbage collecting, since it
1002 doesn't matter in that case.
1003 (deliver_profiler_signal): Rename from sigprof_handler,
1004 for consistency with other handlers.
1005 (setup_cpu_timer): New function, with much of what used to be in
1006 Fprofiler_cpu_start. Check for out-of-range argument.
1007 Prefer timer_settime if available, and prefer
1008 thread cputime clocks, then process cputime clocks, then
1009 monotonic clocks, to the old realtime clock. Use make_timeval
1010 to round more-correctly when falling back to setitimer.
1011 (Fprofiler_cpu_start): Use it.
1012 (Fprofiler_cpu_stop): Prefer timer_settime if available.
1013 Don't assume that passing NULL as the 2nd argument of setitimer
1014 is the same as passing a pointer to all-zero storage.
1015 Ignore SIGPROF afterwards.
1016 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
1017 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
1018 non-fatal signal handlers. Ignore SIGPROF on startup.
1019 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
1020 in profiler.c, since sysdep.c now uses it.
1022 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.
1023 Suggested by Eli Zaretskii in
1024 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.

1037 (Fbacktrace_frame): Adjust accordingly.
1039 2012-09-28 Glenn Morris <rgm@gnu.org>
1041 * eval.c (Frun_hook_with_args, Frun_hook_with_args_until_success)
1042 (Frun_hook_with_args_until_failure): Doc fixes.
1044 2012-09-28 Eli Zaretskii <eliz@gnu.org>
1046 * xdisp.c (syms_of_xdisp) <Qredisplay_internal>: Rename from
1047 Qautomatic_redisplay and change the symbol name. All users changed.
1049 2012-09-28 Tomohiro Matsuyama <tomo@cx4a.org>
1051 * profiler.c (sigprof_handler): Fix race condition.
1053 2012-09-28 Glenn Morris <rgm@gnu.org>

1057 2012-09-27 Paul Eggert <eggert@cs.ucla.edu>
1059 Check more robustly for timer_settime.
1060 * Makefile.in (LIB_TIMER_TIME): New macro.
1062 * atimer.c (alarm_timer, alarm_timer_ok, set_alarm, init_atimer):
1063 Use HAVE_TIMER_SETTIME, not SIGEV_SIGNAL, to decide whether to

1068 * profiler.c (Fprofiler_cpu_start): Remove unnecessary flag SA_SIGINFO.
1070 2012-09-26 Juanma Barranquero <lekktu@gmail.com>
1072 * makefile.w32-in ($(BLD)/profiler.$(O)): Update dependencies.
1074 2012-09-26 Paul Eggert <eggert@cs.ucla.edu>
1076 * character.h (MAYBE_UNIFY_CHAR): Remove.
1077 * charset.c, charset.h (maybe_unify_char): Now static.
1078 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
1079 Since this stuff is now private to charset.c, there's no need for
1080 a public macro and no need to inline by hand.
1082 2012-09-26 Tomohiro Matsuyama <tomo@cx4a.org>
1083 Stefan Monnier <monnier@iro.umontreal.ca>
1084 Juanma Barranquero <lekktu@gmail.com>

1111 * makefile.w32-in ($(BLD)/callproc.$(O)): Update dependencies.
1113 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>
1115 Prefer POSIX timers if available.
1116 They avoid a race if the timer is too close to the current time.
1117 * atimer.c (alarm_timer, alarm_timer_ok) [SIGEV_SIGNAL]: New static vars.
1118 (set_alarm) [SIGEV_SIGNAL]: Use POSIX timers if available.
1119 (init_atimer) [SIGEV_SIGNAL]: Initialize them.
1121 2012-09-25 Eli Zaretskii <eliz@gnu.org>
1123 * coding.c (CHAR_STRING_ADVANCE_NO_UNIFY): Make it an alias of
1124 CHAR_STRING_ADVANCE.
1125 (STRING_CHAR_ADVANCE_NO_UNIFY): Make it an alias of
1126 STRING_CHAR_ADVANCE.
1128 2012-09-25 Juanma Barranquero <lekktu@gmail.com>
1130 Move Vlibrary_cache to emacs.c and reset before dumping.
1132 * lisp.h (reset_image_types): Declare.

1142 (globals_of_w32) <Vlibrary_cache>: Do not initialize.
1144 * w32.h (Vlibrary_cache): Do not declare.
1146 2012-09-25 Eli Zaretskii <eliz@gnu.org>
1148 * w32proc.c (sys_signal): Handle all signals defined by the
1149 MS-Windows runtime, not just SIGCHLD. Actually install the signal
1150 handlers for signals supported by Windows. Don't override
1151 term_ntproc as the handler for SIGABRT.
1152 (sigaction): Rewrite to call sys_signal instead of duplicating its
1154 (sys_kill): Improve commentary.
1156 * w32.c (term_ntproc): Accept (and ignore) one argument, for
1157 consistency with a signature of a signal handler. All callers
1159 (init_ntproc): Accept an argument DUMPING. If dumping, don't
1160 install term_ntproc as a signal handler for SIGABRT, as that
1161 should be done by the dumped Emacs.
1163 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
1165 * w32select.c (term_w32select): Protect against repeated
1166 invocation by setting clipboard_owner to NULL after calling
1169 * emacs.c (shut_down_emacs, main): Adapt the calls to init_ntproc
1170 and term_ntproc to their modified signatures.
1172 * character.c (char_string, string_char): Remove calls to
1173 MAYBE_UNIFY_CHAR. See the discussion starting at
1174 http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00433.html
1177 2012-09-25 Chong Yidong <cyd@gnu.org>
1179 * xdisp.c (mode_line_inverse_video): Delete obsolete variable.
1181 2012-09-24 Stefan Monnier <monnier@iro.umontreal.ca>
1183 * bytecode.c (exec_byte_code): Signal an error instead of aborting,
1184 when encountering an unknown bytecode.
1186 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
1188 image.c, indent.c: Use bool for booleans.
1189 * dispextern.h (struct image_type): Members valid_p, load, init
1190 now return bool, not int. All uses changed.
1191 * image.c: Omit unnecessary static decls.
1192 (x_create_bitmap_mask, x_build_heuristic_mask):

1230 Move pid_t related decls out of lisp.h.
1231 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
1232 (interruptible_wait_for_termination):
1233 Move these decls from lisp.h to syswait.h, since they use pid_t.
1234 Needed on FreeBSD; see Herbert J. Skuhra in
1235 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
1236 * callproc.c: Include syswait.h.

1256 Use bool for boolean.
1257 * gtkutil.c (xg_update_frame_menubar):

1282 2012-09-23 Eli Zaretskii <eliz@gnu.org>
1284 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
1285 fatal_error_backtrace.
1287 * w32proc.c (sys_kill): Undo last change: don't do anything when
1288 invoked to deliver SIGABRT to our own process. This is now
1289 handled by emacs_raise.
1291 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
1293 * w32term.c (w32_read_socket): Remove leftover reference to
1294 interrupt_input_pending.
1296 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
1298 Do not use SA_NODEFER.
1299 Problem reported by Dani Moncayo in
1300 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
1302 * sysdep.c (emacs_abort): Do not reset signal handler.
1303 * emacs.c (terminate_due_to_signal): Reset signal handler here.
1304 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
1305 wanted even on POSIXish hosts, and it doesn't work on Windows.
1307 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
1309 * xterm.c (x_term_init): Call fixup_locale before and after calling
1310 gtk_init (Bug#12392).
1312 2012-09-23 Chong Yidong <cyd@gnu.org>
1314 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
1315 Vdynamic_library_alist.
1317 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
1318 (Fgnutls_available_p): Caller changed.
1320 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
1321 (Flibxml_parse_xml_region): Likewise.
1323 * dispextern.h (struct image_type): Remove arg from init function.
1325 * image.c (Finit_image_library, lookup_image_type)
1326 (define_image_type): Remove now-unneeded second arg.
1327 (init_xpm_functions, init_png_functions, init_jpeg_functions)
1328 (init_tiff_functions, init_gif_functions, init_svg_functions):
1329 Arglist and w32_delayed_load calling convention changed.
1330 (gs_type): Remove init_gs_functions; there is no such function.
1331 (valid_image_p, make_image): Fix caller to lookup_image_type.
1333 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
1335 Simplify and avoid signal-handling races (Bug#12471).
1337 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
1338 Avoid recursive loop if there's a fatal error in the function itself.
1339 * atimer.c (pending_atimers):
1340 * blockinput.h: Don't include "atimer.h"; no longer needed.
1341 (interrupt_input_pending): Remove. All uses removed.
1342 pending_signals now counts both atimers and ordinary interrupts.
1343 This is less racy than having three separate pending-signal flags.
1344 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
1346 Rename from their upper-case counterparts BLOCK_INPUT,
1347 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
1348 INPUT_BLOCKED_P, and turn into functions. All uses changed.
1349 This makes it easier to access volatile variables more accurately.
1350 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
1351 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
1352 that's more reliable if the code is buggy and sets
1353 interrupt_input_blocked to a negative value. All uses changed.
1354 * atimer.c (deliver_alarm_signal):
1355 Remove. No need to deliver this to the parent; any thread can
1356 handle this signal now. All uses replaced by underlying handler.
1357 * atimer.c (turn_on_atimers):
1358 * dispnew.c (handle_window_change_signal):
1359 * emacs.c (handle_danger_signal):
1360 * keyboard.c (kbd_buffer_get_event):
1361 Don't reestablish signal handler; not needed with sigaction.
1362 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
1364 Rework to avoid unnecessary accesses to volatile variables.
1365 (UNBLOCK_INPUT_TO): Now a function.
1366 (totally_unblock_input, unblock_input): New decls.
1367 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
1368 (init_data): Remove. Necessary stuff now done in init_signal.
1369 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
1370 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
1371 (fatal_error_code): Remove; no longer needed.
1372 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
1373 it doesn't always backtrace. All uses changed. No need to reset
1374 signal to default, since sigaction and/or die does that for us now.
1375 Use emacs_raise (FOO), not kill (getpid (), FOO).
1376 (main): Check more-accurately whether we're dumping.
1377 Move fatal-error setup to sysdep.c
1378 * floatfns.c: Do not include "syssignal.h"; no longer needed.
1379 * gtkutil.c (xg_get_file_name, xg_get_font):
1380 Remove no-longer-needed signal-mask manipulation.
1381 * keyboard.c, process.c (POLL_FOR_INPUT):
1382 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
1383 * keyboard.c (read_avail_input): Remove.
1384 All uses replaced by gobble_input.
1385 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
1386 (kbd_buffer_store_event_hold, gobble_input):
1387 (record_asynch_buffer_change) [USABLE_SIGIO]:
1388 (store_user_signal_events):
1389 No need to mess with signal mask.
1390 (gobble_input): If blocking input and there are terminals, simply
1391 set pending_signals to 1 and return. All hooks changed to not
1392 worry about whether input is blocked.
1393 (process_pending_signals): Clear pending_signals before processing
1394 them, in case a signal comes in while we're processing.
1395 By convention callers now test pending_signals before calling us.
1396 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
1397 New functions, to support changes to blockinput.h.
1398 (handle_input_available_signal): Now extern.
1399 (reinvoke_input_signal): Remove. All uses replaced by
1401 (quit_count): Now volatile, since a signal handler uses it.
1402 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
1403 All callers changed. Block SIGINT only if not already blocked.
1404 Clear sigmask reliably, even if Fsignal returns, which it can.
1405 Omit unnecessary accesses to volatile var.
1406 (quit_throw_to_read_char): No need to restore sigmask.
1407 * keyboard.c (gobble_input, handle_user_signal):
1408 * process.c (wait_reading_process_output):
1409 Call signal-handling code rather than killing ourselves.
1410 * lisp.h: Include <float.h>, for...
1411 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
1412 (pending_signals): Now volatile.
1413 (syms_of_data): Now const if IEEE floating point.
1414 (handle_input_available_signal) [USABLE_SIGIO]:
1415 (terminate_due_to_signal, record_child_status_change): New decls.
1416 * process.c (create_process): Avoid disaster if memory is exhausted
1417 while we're processing a vfork, by tightening the critical section
1419 (send_process_frame, process_sent_to, handle_pipe_signal)
1420 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
1422 (send_process): No need for setjmp/longjmp any more, since the
1423 SIGPIPE stuff is now gone. Instead, report an error if errno
1425 (record_child_status_change): Now extern. PID and W are now args.
1426 Return void, not bool. All callers changed.
1427 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
1428 Remove. All uses removed. This bug should be fixed now in a
1430 (wait_for_termination_1): Use waitpid rather than sigsuspend,
1431 and record the child status change directly. This avoids the
1432 need to futz with the signal mask.
1433 (process_fatal_action): Move here from emacs.c.
1434 (emacs_sigaction_flags): New function, containing
1435 much of what used to be in emacs_sigaction_init.
1436 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
1437 caught by emacs, to make races less likely.
1438 (deliver_process_signal): Rename from handle_on_main_thread.
1440 (BACKTRACE_LIMIT_MAX): Now at top level.
1441 (thread_backtrace_buffer, threadback_backtrace_pointers):
1443 (deliver_thread_signal, deliver_fatal_thread_signal):
1444 New functions, for more-accurate delivery of thread-specific signals.
1445 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
1446 (deliver_arith_signal): Handle in this thread, not
1447 in the main thread, since it's triggered by this thread.
1448 (maybe_fatal_sig): New function.
1449 (init_signals): New arg DUMPING so that we can be more accurate
1450 about whether we're dumping. Caller changed.
1451 Treat thread-specific signals differently from process-general signals.
1452 Block all signals while handling fatal error; that's safer.
1453 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
1455 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
1456 Ignore SIGPIPE unless batch.
1457 (emacs_backtrace): Output backtrace for the appropriate thread,
1458 which is not necessarily the main thread.
1459 * syssignal.h: Include <stdbool.h>.
1460 (emacs_raise): New macro.
1461 * xterm.c (x_connection_signal): Remove; no longer needed
1462 now that we use sigaction.
1463 (x_connection_closed): No need to mess with sigmask now.
1464 (x_initialize): No need to reset SIGPIPE handler here, since
1465 init_signals does this for us now.
1467 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
1469 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
1470 background rect may be larger (Bug#12245).
1472 2012-09-23 Chong Yidong <cyd@gnu.org>
1474 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
1476 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
1478 * .gdbinit: Just stop at fatal_error_backtrace.
1479 See Stefan Monnier's request in
1480 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
1481 Remove no-longer-used query of system type.
1483 2012-09-22 Chong Yidong <cyd@gnu.org>
1485 * search.c (Freplace_match): Doc fix (Bug#12325).
1487 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
1489 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
1490 (Fline_end_position): Doc fix.
1492 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
1494 2012-09-22 Chong Yidong <cyd@gnu.org>
1496 * dispextern.h (struct image_type): Add new slot, storing a type
1497 initialization function.
1499 * image.c (define_image_type): Call the image initializer function
1500 if it is defined. Arguments and return value changed.
1501 (valid_image_p, make_image): Callers changed.
1502 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
1503 (gif_type, imagemagick_type, svg_type, gs_type):
1504 Add initialization functions.
1505 (Finit_image_library): Call lookup_image_type.
1506 (CHECK_LIB_AVAILABLE): Macro deleted.
1507 (lookup_image_type): Call define_image_type here, rather than via
1508 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
1509 (syms_of_image): Move define_image_type calls for xbm_type and
1510 pbm_type to lookup_image_type.
1512 2012-09-22 Eli Zaretskii <eliz@gnu.org>
1514 * keyboard.c (timer_check_2): Move calculation of 'timers' and
1515 'idle_timers' from here ...
1516 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
1517 lists, to avoid infloops when the timer does something stupid,
1518 like reinvoke itself with the same or smaller time-out.
1521 2012-09-22 Martin Rudalics <rudalics@gmx.at>
1523 * window.c (Fsplit_window_internal): Handle only Qt value of
1524 Vwindow_combination_limit separately.
1525 (Qtemp_buffer_resize): New symbol.
1526 (Vwindow_combination_limit): New default value.
1529 2012-09-22 Eli Zaretskii <eliz@gnu.org>
1531 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
1532 the new overlay string. (Bug#10159)
1534 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
1536 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
1537 or that fprintf is async-signal-safe. POSIX doesn't require
1540 2012-09-22 Chong Yidong <cyd@gnu.org>
1542 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
1545 2012-09-22 Kenichi Handa <handa@gnu.org>
1547 * composite.c (composition_reseat_it): Handle the case that a
1548 grapheme cluster is not covered by a single font (Bug#12352).
1550 2012-09-21 Chong Yidong <cyd@gnu.org>
1552 * image.c (define_image_type): Avoid adding duplicate types to
1553 image_types (Bug#12463). Suggested by Jörg Walter.
1555 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1557 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
1558 (print_load_command_name): Add case LC_DATA_IN_CODE.
1559 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
1561 2012-09-21 Glenn Morris <rgm@gnu.org>
1563 * eval.c (Frun_hook_with_args_until_success)
1564 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
1566 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
1568 * fileio.c (Ffile_selinux_context): Only call freecon when
1569 lgetfilecon succeeded.
1570 (Fset_file_selinux_context): Likewise. (Bug#12444)
1572 2012-09-21 Eli Zaretskii <eliz@gnu.org>
1574 * xdisp.c (try_window_reusing_current_matrix): Under bidi
1575 reordering, locate the cursor by calling set_cursor_from_row; if
1576 that fails, clear the desired glyph matrix before returning a
1577 failure indication to the caller. Fixes leaving garbled display
1578 when fast scrolling with a down-key. (Bug#12403)
1579 (compute_stop_pos_backwards): Fix a typo that caused crashes while
1580 scrolling through multibyte text.
1582 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
1584 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
1585 calling mark_vectorlike since that's the one that marks the window.
1586 (mark_discard_killed_buffers): Mark the final cdr.
1587 * window.h (struct window): Move prev/next_buffers to the
1588 non-standard fields.
1589 * window.c (make_window): Initialize prev/next_buffers manually.
1591 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
1593 Omit unused arg EXPECTED from socket hooks.
1594 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
1595 * nsterm.m (ns_term_init):
1596 * termhooks.h (struct terminal.read_socket_hook):
1597 * w32inevt.c (w32_console_read_socket):
1598 * w32term.c (w32_read_socket):
1599 * xterm.c (XTread_socket):
1600 Omit unused arg EXPECTED. All callers changed.
1601 (store_user_signal_events): Return void, not int, since callers no
1602 longer care about the return value. All uses changed.
1604 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
1606 * w32gui.h (XParseGeometry): Do not declare.
1608 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
1610 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
1611 Ignore 'expected'. See Eli Zaretskii in
1612 <http://bugs.gnu.org/12471#8> (last line).
1614 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
1615 (XParseGeometry): Now static. Substitute extremal values for
1616 values that are out of range.
1618 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
1620 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
1622 * nsfns.m (XParseGeometry): Remove.
1623 (Fx_create_frame): Call x_set_offset to correctly interpret
1624 top_pos in geometry.
1626 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
1627 (Fx_parse_geometry): If there is a space in string, call
1628 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
1630 2012-09-17 Eli Zaretskii <eliz@gnu.org>
1632 * search.c (scan_buffer): Use character positions in calls to
1633 region_cache_forward and region_cache_backward, not byte
1634 positions. (Bug#12196)
1636 * w32term.c (w32_read_socket): Set pending_signals to 1, like
1637 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
1639 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
1640 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
1641 emacs_blocked_malloc, now deleted.
1643 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
1645 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
1646 The workaround was for improving performance on Solaris 2.4, but
1647 is getting in the way now. Emacs will still work if someone is
1648 still running Solaris 2.4 in a museum somewhere; Sun dropped
1649 support for Solaris 2.4 in 2003.
1650 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
1651 * process.c (create_process) [HAVE_WORKING_VFORK]:
1652 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
1653 since Emacs no longer uses vfork on that platform.
1655 2012-09-17 Glenn Morris <rgm@gnu.org>
1657 * emacs.c: Use COPYRIGHT.
1659 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
1661 Remove configure's --without-sync-input option (Bug#12450).
1662 When auditing signal-handling in preparation for cleaning it up,
1663 I found that SYNC_INPUT has race conditions and would be a real
1664 pain to fix. Since it's an undocumented and deprecated
1665 configure-time option, now seems like a good time to remove it.
1666 Also see <http://bugs.gnu.org/11080#16>.
1667 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
1668 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
1669 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
1670 (malloc_hysteresis):
1671 (check_depth) [XMALLOC_OVERRUN_CHECK]:
1672 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
1673 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
1674 (dont_register_blocks, bytes_used_when_reconsidered)
1675 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
1676 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
1677 [!SYSTEM_MALLOC && !SYNC_INPUT]:
1678 Remove. All uses removed.
1679 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
1680 implementation, one that depends on whether the new macro
1681 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
1683 * atimer.c (run_timers, handle_alarm_signal):
1684 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
1685 (handle_async_input, process_pending_signals)
1686 (handle_input_available_signal, init_keyboard):
1687 * nsterm.m (ns_read_socket):
1688 * process.c (wait_reading_process_output):
1689 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
1690 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
1692 * xterm.c (XTread_socket):
1694 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
1695 * eval.c (handling_signal): Remove. All uses removed.
1696 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
1697 All uses replaced with the SYNC_INPUT version.
1698 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
1700 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
1703 * font.c (Ffont_shape_gstring): Remove unused local.
1705 2012-09-16 Glenn Morris <rgm@gnu.org>
1707 * Makefile.in (clean): No longer run nextstep's clean.
1709 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
1711 (ns-app): Move here from ns.mk, and simplify.
1712 (clean): Simplify nextstep entry.
1713 * ns.mk: Remove file.
1715 2012-09-17 Kenichi Handa <handa@gnu.org>
1717 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
1718 not covert the last few charactes.
1720 2012-09-16 Kenichi Handa <handa@gnu.org>
1722 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
1723 here, but just check the validity of glyphs in the glyph-string.
1725 2012-09-16 Martin Rudalics <rudalics@gmx.at>
1727 * window.c (Fwindow_parameter, Fset_window_parameter):
1728 Accept any window as argument (Bug#12452).
1730 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
1732 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
1733 to ns_term_init to avoid memory leak.
1735 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
1736 explicit retain/release.
1737 (ns_term_init): Only allow one display. Initialize outerpool and
1740 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
1742 Port _setjmp fix to POSIXish hosts as well as Microsoft.
1743 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
1744 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
1745 the Microsoft problem in a different way, by altering ../nt/config.nt.
1747 2012-09-15 Eli Zaretskii <eliz@gnu.org>
1762 * w16select.c: Remove inclusion of setjmp.h, as it is now included
1763 by lisp.h. This completes removal of setjmp.h inclusion
1764 erroneously announced in the previous commit. (Bug#12446)
1766 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
1769 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
1770 not defined as a macro. The latter happens on MS-Windows.
1773 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
1775 Port better to POSIX hosts lacking _setjmp (Bug#12446).
1776 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
1777 Some instances of '#include <setjmp.h>' removed, if the
1778 only reason for the instance was because "lisp.h" was included.
1779 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
1780 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
1781 and _longjmp with the new symbols. Emacs already uses _setjmp if
1782 available, so this change affects only POSIXish hosts that have
1783 sigsetjmp but not _setjmp, such as some versions of Solaris and
1784 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
1785 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
1786 (png_load_body) [HAVE_PNG]:
1787 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
1788 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
1789 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
1790 since PNG requires jmp_buf. This is the only exception to the
1791 general rule that we now use sys_setjmp and sys_longjmp.
1792 This exception is OK since this code does not change the signal
1793 mask or longjmp out of a signal handler.
1795 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
1797 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
1798 Include "syssignal.h", for 'main_thread'.
1800 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
1802 Avoid out-of-range marker position (Bug#12426).
1803 * insdel.c (replace_range, replace_range_2):
1804 Adjust markers before overlays, as suggested by comments.
1805 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
1806 Remove redundant check before calling offset_intervals.
1808 2012-09-14 Martin Rudalics <rudalics@gmx.at>
1810 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
1811 current buffer (Bug#12387).
1813 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
1815 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
1817 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
1819 Use a more backwards-compatible timer format (Bug#12430).
1820 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
1821 vector element, not from the 4th, since PSECS is now at the end.
1822 (Fcurrent_idle_time): Doc fix.
1824 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
1826 Function to mark objects and remove killed buffers at once.
1827 * alloc.c (discard_killed_buffers): Rename to ...
1828 (mark_discard_killed buffers) ... new name. Add marking
1829 of remaining objects. Fix comment. Adjust users.
1830 (mark_object): Do not touch frame buffer lists here.
1831 * frame.c (delete_frame): Reset frame buffer lists here.
1833 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
1835 Better workaround for GNOME bug when --enable-gcc-warnings.
1836 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
1837 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
1838 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
1840 Simplify SIGIO usage (Bug#12408).
1841 The code that dealt with SIGIO was crufty and confusing, e.g., it
1842 played tricks like "#undef SIGIO" but these tricks were not used
1843 consistently. Simplify mostly by not #undeffing standard symbols,
1844 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
1845 or not as we please) rather than "defined SIGIO" (standard symbol
1846 that we probably shouldn't #undef).
1847 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
1848 Modules that need it can include it.
1849 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
1850 * dispextern.h (ignore_sigio): New decl.
1851 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
1852 unconditionally, since it's now a no-op if !USABLE_SIGIO.
1853 * emacs.c (shut_down_emacs):
1854 * keyboard.c (kbd_buffer_store_event_hold):
1855 Use ignore_sigio rather than invoking 'signal' directly.
1856 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
1858 (FIONREAD, SIGIO): Do not #undef.
1859 (tty_read_avail_input): Use #error rather than a syntax error.
1860 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
1861 for I_PIPE, used by SETUP_SLAVE_PTY.
1862 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
1863 * sysdep.c (croak): Remove; no longer needed. This bit of
1864 temporary code, with Fred N. Fish's comment that it's temporary,
1865 has been in Emacs since at least 1992!
1866 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
1867 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
1868 * syssignal.h (croak): Remove decl.
1869 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
1870 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
1871 now that we're termios-only.
1872 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
1873 * term.c (dissociate_if_controlling_tty): Use #error rather than
1876 Work around GCC and GNOME bugs when --enable-gcc-warnings.
1877 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
1878 to work around GNOME bug 683906.
1879 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
1880 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
1881 This works around GCC bug 54561.
1883 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
1885 More fixes for 'volatile' and setjmp/longjmp.
1886 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
1887 * image.c (struct png_load_context) [HAVE_PNG]: New type.
1888 (png_load_body) [HAVE_PNG]:
1889 (jpeg_load_body) [HAVE_JPEG]:
1890 New function, with most of the old parent function's body.
1891 (png_load) [HAVE_PNG]:
1892 (jpeg_load) [HAVE_JPEG]:
1893 Invoke the new function, to avoid longjmp munging our locals.
1894 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
1895 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
1896 longjmp is passed 2, as the C standard doesn't guarantee this.
1897 Instead, store the failure code into mgr->failure_code.
1899 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
1901 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
1902 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
1903 (syms_of_keyboard): Remove support for unread-command-char.
1905 2012-09-12 Eli Zaretskii <eliz@gnu.org>
1907 * w32proc.c (sys_kill): If PID is our process ID and the signal is
1908 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
1909 violation. (Bug#12426)
1911 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
1913 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
1915 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
1917 * eval.c: Add `inhibit-debugger'.
1918 (Qinhibit_debugger): New symbol.
1919 (call_debugger): Bind it instead of Qdebug_on_error.
1920 (maybe_call_debugger): Test Vinhibit_debugger.
1921 (syms_of_eval): Define inhibit-debugger.
1922 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
1923 (syms_of_xdisp): Remove inhibit-debug-on-message.
1925 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
1927 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
1928 If a nonvolatile local variable is written before a _longjmp to
1929 the frame containing the variable, and is read after the _longjmp,
1930 the value read is indeterminate. Some local variables of type
1931 'struct handler' and 'struct catchtag' are used in this way, so
1932 mark each of their slots as volatile if the slot can be set before
1933 _longjmp and read afterwards.
1934 * lisp.h (struct handler): var and chosen_clause are now volatile.
1935 (struct catchtag): val, next, and pdlcount are now volatile.
1937 * bidi.c (bidi_push_it, bidi_pop_it):
1938 * fns.c (copy_hash_table):
1939 * image.c (define_image_type):
1940 * keyboard.c (kbd_buffer_store_event_hold):
1941 * process.c (Fprocess_send_eof):
1942 * xfaces.c (x_create_gc) [HAVE_NS]:
1943 * xgselect.c (xg_select):
1944 Prefer assignment to memcpy when either will do.
1946 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
1947 Use pointer-to-a-pointer to simplify and avoid a NILP check each
1948 time an item is removed. No need to mark this function 'inline';
1949 the compiler knows better than we do.
1951 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
1953 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
1954 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
1955 to change_frame_size (Bug#12388).
1956 (windowDidResize:): Pass YES to updateFrameSize.
1958 * nsterm.h: Add delay parameter to updateFrameSize.
1960 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
1962 Discard killed buffers from deleted window and frame objects.
1963 This reduces an amount of references to killed buffers and
1964 helps GC to reclaim them faster.
1965 * alloc.c (discard_killed_buffers): New function.
1966 (mark_object): Use it for deleted windows and frames.
1967 (mark_object): If symbol's value is set up for a killed buffer
1968 or deleted frame, restore it's global binding.
1969 * data.c (swap_in_global_binding): Add GC notice.
1970 (swap_in_symval_forwarding): Use convenient set_blv_where.
1971 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
1972 * window.h: ... to here.
1974 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
1976 Convenient macro to check whether the buffer is live.
1977 * buffer.h (BUFFER_LIVE_P): New macro.
1978 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
1979 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
1981 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1983 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
1984 composition cases (Bug#12364).
1986 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
1987 overhang of succeeding glyphs overlapping box cursor.
1989 * w32term.c (x_draw_glyph_string): Likewise.
1991 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
1993 Simplify, document, and port floating-point (Bug#12381).
1994 The porting part of this patch fixes bugs on non-IEEE platforms
1995 with frexp, ldexp, logb.
1996 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
1998 * floatfns.c: Simplify discussion of functions that Emacs doesn't
1999 support, by removing commented-out code and briefly listing the
2000 C89 functions excluded. The commented-out stuff was confusing
2001 maintenance, e.g., we thought we needed cbrt but it was commented out.
2002 (logb): Remove decl; no longer needed.
2003 (isfinite): New macro, if not already supplied.
2004 (isnan): Don't replace any existing macro.
2005 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
2006 are present on all C89 platforms.
2007 (Ffrexp): Do not special-case zero, as frexp does the right thing
2009 (Flogb): Do not use logb, as it doesn't have the desired meaning
2010 on hosts that use non-base-2 floating point. Instead, stick with
2011 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
2012 frexp, to avoid getting an unspecified result.
2014 * xdisp.c (Qinhibit_debug_on_message): Now static.
2016 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
2018 * nsterm.m (ns_update_begin): Set clip path to whole view by using
2019 NSBezierPath (Bug#12131).
2021 2012-09-10 Chong Yidong <cyd@gnu.org>
2023 * fns.c (Fdelq, Fdelete): Doc fix.
2025 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
2027 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
2028 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
2030 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
2032 * lisp.h (make_lisp_ptr): New macro to replace XSET.
2033 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
2036 2012-09-09 Eli Zaretskii <eliz@gnu.org>
2038 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
2039 left fringe if the window has a left margin. This avoids leaving
2040 traces of the cursor because its leftmost pixel is not drawn over.
2042 * dispnew.c (update_window_line): When the left margin area of a
2043 screen line is updated, set the redraw_fringe_bitmaps_p flag of
2044 that screen line. (Bug#12277)
2046 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
2048 Assume C89 or later for math functions (Bug#12381).
2049 This simplifies the code, and makes it a bit smaller and faster,
2050 and (most important) makes it easier to clean up signal handling
2051 since we can stop worring about floating-point exceptions in
2052 library code. That was a problem before C89, but the problem
2053 went away many years ago on all practical Emacs targets.
2054 * data.c, image.c, lread.c, print.c:
2055 Don't include <math.h>; no longer needed.
2056 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
2057 might be autoconfigured, as that never happens.
2059 * doprnt.c (DBL_MAX_10_EXP):
2060 * print.c (DBL_DIG):
2061 Remove. C89 or later always defines these.
2062 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
2063 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
2064 (arith_error, domain_error, domain_error2):
2065 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
2066 no longer needed -- we simply return what C returns. All uses removed.
2067 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
2069 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
2070 Remove. All uses expanded, as these macros are no longer used
2071 more than once and are now more trouble than they're worth.
2072 (Ftan): Use tan, not sin / cos.
2073 (Flogb): Assume C89 frexp.
2074 (fmod_float): Assume C89 fmod.
2075 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
2076 (init_floatfns): Remove. All uses removed.
2078 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
2080 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
2081 compositeToPoint for OSX < 10.6 (Bug#12390).
2083 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
2085 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
2086 This produces more-accurate results.
2088 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
2090 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
2091 changes (Bug#12088).
2093 2012-09-08 Chong Yidong <cyd@gnu.org>
2095 * syntax.c (Fstring_to_syntax): Doc fix.
2097 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
2099 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
2100 in the internal border.
2101 (x_set_window_size): Remove static variables and their usage.
2102 (ns_redraw_scroll_bars): Fix NSTRACE arg.
2103 (ns_after_update_window_line, ns_draw_fringe_bitmap):
2104 Remove fringe/internal border adjustment (Bug#11052).
2105 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
2106 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
2107 (ns_fix_rect_ibw): Remove.
2108 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
2109 (ns_dumpglyphs_box_or_relief): Ditto.
2110 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
2112 (ns_dumpglyphs_image): Ditto.
2113 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
2115 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
2116 their usage. Add fringe_extended_p and its use as in other terms.
2117 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
2118 scroll bar was removed.
2119 (updateFrameSize): New function.
2120 (windowDidResize): Move code to updateFrameSize and call it.
2122 * nsterm.h (EmacsView): Add updateFrameSize.
2124 2012-09-07 Chong Yidong <cyd@gnu.org>
2126 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
2128 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
2130 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
2132 More signal-handler cleanup (Bug#12327).
2133 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
2134 Problem introduced when merging patches. Noted by Eli Zaretskii in
2135 <http://bugs.gnu.org/12327#67>.
2136 * floatfns.c: Comment fix.
2137 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
2138 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
2139 and anyway the declaration is harmless even if SIGDANGER is not defined.
2140 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
2141 defined BROKEN_FIONREAD). systty.h formerly did this, but other
2142 source files not surprisingly expected syssignal.h to define, or
2143 not define, SIGIO, and it's cleaner to do it that way, for consistency.
2144 Include <sys/ioctl.h>, for FIONREAD.
2145 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
2146 This eliminates a problem whereby other files mysteriously had
2147 to include "syssignal.h" before including "systty.h" if they
2148 wanted to use "#ifdef SIGIO".
2150 2012-09-07 Eli Zaretskii <eliz@gnu.org>
2152 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
2154 * w32.c (sigemptyset): Empty the set.
2155 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
2157 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
2159 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
2161 * alloc.c (mark_buffer): Revert unsafe marking optimization.
2162 (mark_object): Likewise for frame objects.
2164 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
2166 * syssignal.h (handle_on_main_thread): Always declare,
2167 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
2168 This ports to platforms without HAVE_PTHREAD.
2170 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
2172 Signal-handler cleanup (Bug#12327).
2173 Emacs's signal handlers were written in the old 4.2BSD style with
2174 sigblock and sigmask and so forth, and this led to some
2175 inefficiencies and confusion. Rewrite these to use
2176 pthread_sigmask etc. without copying signal sets around. Also,
2177 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
2178 'signal', and instead use functions that do not attempt to take
2179 over the system name space. This patch causes Emacs's text
2180 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
2181 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
2182 Do not include <signal.h> or "syssignal.h", as these
2183 modules do not use signals.
2184 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
2185 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
2186 Do not include <signal.h>, as "syssignal.h" does that for us now.
2187 * atimer.c (sigmask_atimers): New function.
2188 (block_atimers, unblock_atimers): New functions,
2189 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
2191 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
2192 no longer needed here.
2193 * emacs.c (main): Inspect existing signal handler with sigaction,
2194 so that there's no need to block and unblock SIGHUP.
2195 * sysdep.c (struct save_signal): New member 'action', replacing
2196 old member 'handler'.
2197 (save_signal_handlers, restore_signal_handlers):
2198 Use sigaction instead of 'signal' to save and restore.
2199 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
2200 New function. All users of 'signal' modified to use set_sighandler
2201 if they're writeonly, and to use sys_signal if they're read+write.
2202 (emacs_sigaction_init, forwarded_signal): New functions.
2203 (sys_signal): Remove. All uses replaced by calls to sigaction
2204 and emacs_sigaction_init, or by direct calls to 'signal'.
2205 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
2206 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
2207 all uses replaced by pthread_sigmask etc. calls.
2208 * syssignal.h: Include <signal.h>.
2209 (emacs_sigaction_init, forwarded_signal): New decls.
2210 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
2211 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
2212 (sigmask, sys_sigmask): Remove; no longer needed.
2213 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
2214 (sigblock, sigunblock, sigfree):
2215 (sigsetmask) [!defined sigsetmask]:
2216 Remove. All uses replaced by pthread_sigmask.
2217 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
2218 no longer need to be replaced, and its typical old uses
2219 are now done via emacs_sigaction_init and sigaction.
2220 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
2221 (sys_sigdel): Remove; unused.
2222 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
2224 2012-09-06 Eli Zaretskii <eliz@gnu.org>
2226 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
2227 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
2229 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
2231 Explicitly mark buffer_defaults and buffer_local_symbols.
2232 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
2233 mark_local_symbols here.
2234 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
2235 since special buffers aren't marked here any more.
2236 (allocate_buffer): Chain new buffer with all_buffers here...
2237 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
2239 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
2240 (syms_of_buffer): Remove staticpro of the above.
2241 (init_buffer_once): Set names for buffer_defaults and
2242 buffer_local_symbols.
2244 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
2246 Use bool for booleans in font-related modules.
2247 * font.c (font_intern_prop, font_style_to_value)
2248 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
2249 (generate_otf_features, font_check_otf_features, font_check_otf)
2250 (font_match_p, font_list_entities, font_at):
2251 * fontset.c (fontset_id_valid_p, reorder_font_vector
2252 (fontset_find_font, Fset_fontset_font)
2253 (face_suitable_for_char_p) [0]:
2254 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
2255 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
2256 (m17n_flt_initialized, ftfont_shape_by_flt):
2257 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
2258 * nsfont.m (nsfont_draw):
2259 * w32font.c (w32font_draw):
2260 * w32term.c (x_draw_glyphless_glyph_string_foreground):
2261 Use bool for booleans.
2262 * font.h: Adjust to above API changes.
2263 (struct font, struct font_driver, struct font_driver_list):
2264 Use bool for booleans.
2265 (struct font): Remove useless member encoding_type.
2267 * fontset.c, xftfont.c: Omit unnecessary static decls.
2269 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
2271 * alloc.c (mark_object): Revert window marking code
2272 since it's unsafe for the Fset_window_configuration.
2274 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
2276 Fix race conditions with signal handlers and errno (Bug#12327).
2277 Be more systematic about preserving errno whenever a signal
2278 handler returns, even if it's not in the main thread. Do this by
2279 renaming signal handlers to distinguish between signal delivery
2280 and signal handling. All uses changed.
2281 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
2282 * data.c (deliver_arith_signal): Rename from arith_error.
2283 * dispnew.c (deliver_window_change_signal): Rename from
2284 window_change_signal.
2285 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
2286 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
2287 * keyboard.c (deliver_input_available_signal): Rename from
2288 input_available_signal.
2289 (deliver_user_signal): Rename from handle_user_signal.
2290 (deliver_interrupt_signal): Rename from interrupt_signal.
2291 * process.c (deliver_pipe_signal): Rename from send_process_trap.
2292 (deliver_child_signal): Rename from sigchld_handler.
2293 * atimer.c (handle_alarm_signal):
2294 * data.c (handle_arith_signal):
2295 * dispnew.c (handle_window_change_signal):
2296 * emacs.c (handle_fatal_signal, handle_danger_signal):
2297 * keyboard.c (handle_input_available_signal):
2298 * keyboard.c (handle_user_signal, handle_interrupt_signal):
2299 * process.c (handle_pipe_signal, handle_child_signal):
2300 New functions, with the actual signal-handling code taken from the
2301 original respective signal handlers, sans the sporadic attempts to
2302 preserve errno, since that's now done by handle_on_main_thread.
2303 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
2304 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
2305 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
2307 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
2308 Move initialization of main_thread to sysdep.c's init_signals.
2309 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
2310 our usage, and simplifies the mainline code.
2311 (record_child_status_change): New static function, as a helper
2312 for handle_child_signal, and with most of the old child handler's
2314 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
2315 (handle_child_signal): Use the above.
2316 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
2317 Moved here from emacs.c.
2318 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
2319 code moved here from emacs.c's main function.
2320 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
2321 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
2322 This lets callers save and restore errno properly.
2324 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
2326 Remove redundant or unused things here and there.
2327 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
2328 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
2329 * editfns.c (Fcompare_buffer_substrings): Likewise.
2330 * frame.h (struct terminal, struct font_driver_list):
2331 Remove redundant declarations.
2332 * window.h (Qleft, Qright): Likewise.
2334 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
2336 Do not mark objects from deleted buffers, windows and frames.
2337 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
2338 (mark_object): Likewise for windows and frames.
2340 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
2342 * alloc.c (valid_lisp_object_p): Treat killed buffers,
2343 buffer_defaults and buffer_local_symbols as valid objects.
2344 Return special value to denote them.
2346 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
2348 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
2349 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
2350 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
2351 (file_name_absolute_p, Fsubstitute_in_file_name):
2352 (check_executable, check_writable, Ffile_accessible_directory_p)
2353 (Fset_file_selinux_context, Fdefault_file_modes)
2354 (Finsert_file_contents, choose_write_coding_system)
2355 (Fwrite_region, build_annotations, a_write, e_write)
2357 * filelock.c (boot_time_initialized, get_boot_time)
2358 (get_boot_time_1, lock_file_1, within_one_second):
2359 * floatfns.c (in_float):
2360 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
2361 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
2362 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
2363 * lisp.h (struct Lisp_Hash_Table.cmpfn):
2364 * window.c (compare_window_configurations):
2365 Use bool for booleans.
2366 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
2367 (Fdefault_file_modes): Now mode_t, not int, for modes.
2368 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
2369 (internal_delete_file): Now returns void, not a (boolean) int,
2370 since nobody was looking at the return value.
2371 * lisp.h, window.h: Adjust to above API changes.
2373 * xdisp.c (set_message): Simplify and reindent last change.
2375 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
2377 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
2379 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
2381 * eval.c (call_debugger): Make the function non-static so that we
2382 can call it from set_message.
2384 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
2385 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
2387 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
2389 Give more-useful info on a fatal error (Bug#12328).
2390 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
2391 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
2392 of doing the work ourselves.
2393 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
2394 do most of the work.
2395 (fatal_error_backtrace): New function, taken from the guts
2396 of the old fatal_error_signal, but with a new option to output
2398 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
2399 info about the signal than just its number.
2400 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
2401 * sysdep.c: Include <execinfo.h>
2402 (emacs_backtrace): New function, taken partly from the previous
2403 code of the 'die' function.
2404 (emacs_abort): Call fatal_error_backtrace rather than abort.
2406 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
2408 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
2409 eager (load-time) macro-expansion.
2410 * lisp.mk (lisp): Add macroexp.
2412 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
2414 Simplify redefinition of 'abort' (Bug#12316).
2415 Do not try to redefine the 'abort' function. Instead, redo
2416 the code so that it calls 'emacs_abort' rather than 'abort'.
2417 This removes the need for the NO_ABORT configure-time macro
2418 and makes it easier to change the abort code to do a backtrace.
2419 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
2420 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
2421 Remove; sysdep.c's emacs_abort now takes its place.
2422 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
2423 'abort' changed to use 'emacs_abort'.
2424 * msdos.c (dos_abort) [defined abort]: Remove; not used.
2425 (abort) [!defined abort]: Rename to ...
2426 (emacs_abort): ... new name.
2427 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
2428 the place of the old 'abort' in emacs.c.
2429 * w32.c, w32fns.c (abort): Do not #undef.
2430 * w32.c (emacs_abort): Rename from w32_abort.
2432 2012-09-04 Eli Zaretskii <eliz@gnu.org>
2434 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
2435 offsets[j].dv, since the y axis of the screen coordinates points
2436 down, while the y axis of the font definition coordinates points
2437 up. This fixes display of Arabic diacritics such as KASRA and
2438 KASRATAN. (Bug#11860)
2440 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
2442 Be more systematic about _setjmp vs setjmp.
2443 * alloc.c (test_setjmp, mark_stack):
2444 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
2445 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
2446 (png_load, my_error_exit, jpeg_load):
2447 * process.c (send_process_trap, send_process):
2448 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
2449 The underscored versions are up to 30x faster on some hosts.
2450 Formerly, the code used setjmp+longjmp sometimes and
2451 _setjmp+_longjmp at other times, with no particular reason to
2452 prefer setjmp+longjmp.
2454 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
2456 Fix minor problem found by static checking.
2457 * buffer.c (Fdelete_all_overlays): Return nil.
2459 2012-09-03 Martin Rudalics <rudalics@gmx.at>
2461 * buffer.c (Fdelete_all_overlays): New function.
2463 2012-09-03 Chong Yidong <cyd@gnu.org>
2465 * gtkutil.c: Add extern decl for Qxft.
2467 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
2469 * emacs.c, eval.c: Use bool for boolean.
2470 * emacs.c (initialized, inhibit_window_system, running_asynch_code):

2478 * process.c (read_process_output, exec_sentinel):
2479 Use bool for booleans.
2480 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
2481 All callers changed.
2482 * eval.c (interactive_p): Omit always-true boolean argument
2483 EXCLUDE_SUBRS_P. All callers changed.
2484 * dispextern.h, lisp.h: Reflect above API changes.
2485 * firstfile.c (dummy): Use the address of 'main', whose signature
2486 won't change, instead of the address of 'initialize', whose
2487 signature just changed from int to bool.
2488 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
2489 * msdos.c (fatal_error_in_progress): ... from here.
2490 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
2492 (redisplay_internal, unwind_redisplay): Simply clear
2493 REDISPLAYING_P when unwinding, instead of saving its previous,
2494 always-false value and then restoring it.
2496 Clean up some extern decls.
2497 Mostly, this hoists extern decls out of .c files and into .h files.
2498 That way, we're more likely to catch errors if the interfaces change.
2499 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
2500 declare xg_mark_data.
2501 * dispextern.h (x_frame_parm_handlers):
2503 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
2504 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
2505 (Qultra_bold, Qoblique, Qitalic):
2506 Move extern decl here from .c file.
2507 * alloc.c (xg_mark_data) [USE_GTK]:
2509 * eval.c (Qlexical_binding):
2510 * fns.c (time) [!HAVE_UNISTD_H]:

2516 * process.c (QCfamily, QCfilter):
2517 * widget.c (free_frame_faces):
2518 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
2519 * xfont.c (x_clear_errors):
2520 * xterm.c (x_frame_parm_handlers):
2521 Remove now-redundant extern decls.
2522 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
2523 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
2525 * xfaces.c: Remove unnecessary static decls.
2526 * xterm.c (updating_frame): Remove decl of nonexistent object.
2528 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
2529 when building globals.h, as the objects that are not built on
2530 this host are not needed to compile C files on this host.
2532 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
2534 * gtkutil.h: Remove prototype for x_wm_set_size_hint.

2542 (Fdocumentation, Fdocumentation_property, Fsnarf_documentation)
2543 (Fsubstitute_command_keys):

2547 (format_time_string, general_insert_function)
2548 (make_buffer_string, make_buffer_string_both)
2549 (Fsubst_char_in_region, Ftranslate_region_internal, Fformat):
2550 * insdel.c (check_markers, gap_left, adjust_markers_for_insert)
2551 (copy_text, insert_1, insert_1_both, insert_from_string)
2552 (insert_from_string_before_markers, insert_from_string_1)

2559 (adjust_for_invis_intang, set_point_both)
2560 (get_property_and_range, compare_string_intervals)
2561 (set_intervals_multibyte_1, set_intervals_multibyte):
2562 * keyboard.c (decode_timer):
2563 Use bool for boolean.
2564 * intervals.h, lisp.h, systime.h: Reflect above API changes.
2565 * editfns.c (struct info): Use 1-bit unsigned bitfields for booleans.
2567 2012-09-02 Chong Yidong <cyd@gnu.org>
2569 * keymap.c (push_key_description): Print M-TAB as C-M-i
2572 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
2574 * makefile.w32-in (CCL_H, W32FONT_H): New macros.
2575 (ATIMER_H, FONT_H, $(BLD)/alloc.$(O), $(BLD)/callproc.$(O))

2580 ($(BLD)/w32font.$(O), $(BLD)/w32uniscribe.$(O)): Update dependencies.
2582 2012-09-01 Eli Zaretskii <eliz@gnu.org>
2584 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
2585 more than one grapheme cluster passed to the shaper: compute the
2586 offset adjustment values separately for each cluster. (Bug#11860)
2588 * image.c: Restore mistakenly removed inclusion of w32.h. Without
2589 it, GCC doesn't see prototypes of w32_delayed_load, and complains
2590 about implicit conversions from integer to pointer.
2592 2012-09-01 Daniel Colascione <dancol@dancol.org>
2594 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
2595 system used too early.
2597 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
2599 Better seed support for (random).
2600 * emacs.c (main): Call init_random.

2617 window-system headers.
2619 * w32xfns.c (x_sync): Correct definition of x_sync (a no-op here)

2623 directly accessing frame internals.
2625 * w32font.h: Include font.h. Define syms_of_w32font and
2628 * process.c: Include TERM_HEADER instead of listing all possible
2629 window-system headers.
2631 * nsterm.h: Remove declarations now in frame.h.
2632 Define FRAME_X_SCREEN, FRAME_X_VISUAL.
2634 * menu.c: Include TERM_HEADER instead of listing all possible
2635 window-system headers.
2637 * keyboard.h: Declare ignore_mouse_drag_p whenever we have a
2640 * keyboard.c: Include TERM_HEADER instead of listing all possible
2641 window-system headers.
2643 * image.c: Include TERM_HEADER instead of listing all possible
2644 window-system headers. Declare Vlibrary_cache when compiling for
2647 * gtkutil.h (xg_list_node_): Include xterm.h to pick up needed
2648 window system declarations.
2650 * frame.h: Move common functions here: set_frame_menubar,
2651 x_set_window_size, x_sync, x_get_focus_frame,
2652 x_set_mouse_position, x_set_mouse_pixel_position,
2653 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,
2654 x_char_width, x_char_height, x_pixel_width, x_pixel_height,
2655 x_set_frame_alpha, x_set_menu_bar_lines, x_set_tool_bar_lines,

2674 the current window system; include in list of objects to link into
2677 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
2679 Remove mark_ttys function and fix tty_display_info initialization.
2680 * lisp.h (mark_ttys): Remove prototype.
2681 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
2682 to mark_ttys because all possible values of 'top_frame' slot are
2683 the frames which are reachable from Vframe_list.
2684 * term.c (mark_ttys): Remove.
2685 (init_tty): Safely initialize 'top_frame' slot with Qnil.
2687 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
2689 Change struct frame bitfields from unsigned char to unsigned.
2690 * frame.h (struct frame): Change type of 'display_preempted',
2691 'visible', 'iconified', 'has_minibuffer', 'wants_modeline',
2692 'auto_raise', 'auto_lower', 'no_split', 'explicit_name',
2693 'window_sizes_changed', 'mouse_moved' and 'pointer_invisible'
2694 bitfields from unsigned char to unsigned.
2696 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
2698 Remove unused member of struct x_output and struct w32_output.
2699 * xterm.h (struct x_output): Remove unused field 'needs_exposure'.

2702 2012-08-30 Jan Djärv <jan.h.d@swipnet.se>
2704 * gtkutil.c (x_wm_set_size_hint): Use 1 col for base_width so it
2705 does not become zero (Bug#12234).
2707 2012-08-30 Paul Eggert <eggert@cs.ucla.edu>
2709 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
2710 for GCC 4.7.1 x86-64.
2712 2012-08-30 Glenn Morris <rgm@gnu.org>
2714 * lread.c (init_lread): For out-of-tree builds, only add the
2715 source directory's site-lisp dir to the load-path if it exists,
2716 consistent with in-tree builds. (Bug#12302)
2718 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>
2720 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize
2721 button_values to NULL. Call setStykeMask so dialogs get a close button.
2722 (windowShouldClose:): Set window_closed.
2723 (dealloc): New member, free button_values.
2724 (process_dialog:): Make member function. Remove window argument,
2725 replace window with self. Count buttons and allocate and store values
2727 (addButton:value:row:): value is int with the name tag. Call setTag
2728 with tag. Remove return self, declare return value as void.
2729 (addString:row:): Remove return self, declare return value as void.
2730 (addSplit): Remove return self, declare return value as void.
2731 (clicked:): Remove return self, declare return value as void.
2732 Set dialog_return to button_values[seltag]. Code formatting change.
2733 (initFromContents:isQuestion:): Adjust call to process_dialog.
2734 Code formatting change.
2735 (timeout_handler:): Set timer_fired to YES.
2736 (runDialogAt:): Set timer_fired to NO.
2737 Handle click on close button as quit.
2739 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
2740 Add window_closed and button_values. Add void as return value for
2741 add(Button|String|Split). addButton takes int instead of Lisp_Object.
2742 Add process_dialog as new member.
2744 2012-08-28 Eli Zaretskii <eliz@gnu.org>
2746 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it
2747 is not one of the heaps we manage. (Bug#12242)
2749 2012-08-28 Glenn Morris <rgm@gnu.org>
2751 * eval.c (Fcalled_interactively_p): Doc fix. (Bug#11747)

2762 * buffer.c (Fset_buffer_major_mode): Signal an error
2763 if the buffer is dead.
2764 (Fother_buffer, other_buffer_safely): Remove redundant
2767 2012-08-28 Dmitry Antipov <dmantipov@yandex.ru>
2769 Always use set_buffer_if_live to restore original buffer at unwind.
2770 * buffer.h (record_unwind_current_buffer): New function.
2771 * bytecode.c, dispnew.c, editfns.c, fileio.c, fns.c, insdel.c:
2772 * keyboard.c, keymap.c, minibuf.c, print.c, process.c, textprop.c:
2773 * undo.c, window.c: Adjust users.
2774 * buffer.c (set_buffer_if_live): Fix comment.
2776 2012-08-28 Dmitry Antipov <dmantipov@yandex.ru>
2778 Fix usage of set_buffer_internal.
2779 * buffer.h (set_buffer_internal): Make it BUFFER_INLINE.
2780 * buffer.c (set_buffer_if_live): Use set_buffer_internal.
2781 * coding.c (decode_coding): Omit redundant test.
2782 * fileio.c (decide_coding_unwind): Likewise.
2783 * fns.c (secure_hash): Likewise.

2785 * keyboard.c (command_loop_1): Likewise.
2786 * print.c (PRINTFINISH): Likewise.
2787 * xdisp.c (run_window_scroll_functions): Use set_buffer_internal.
2789 2012-08-27 Paul Eggert <eggert@cs.ucla.edu>

2808 Use bool for boolean.
2809 (clear_glyph_matrix_rows): Rename from enable_glyph_matrix_rows,
2810 and remove last int (actually boolean) argument, which was always 0.
2811 All callers changed.
2812 * dispextern.h, frame.h, lisp.h: Reflect above API changes.
2813 * dispextern.h (struct composition_it): Use bool for boolean.
2814 (struct glyph_matrix): Don't assume buffer sizes can fit in 'int'.
2815 (struct bidi_it): Use unsigned:1, not int, for boolean prev_was_pdf.
2816 * dired.c (file_name_completion):
2817 Use bool for boolean. (This was missed in an earlier change.)
2819 2012-08-27 Martin Rudalics <rudalics@gmx.at>
2821 * window.c (Fset_window_configuration): Revert first part of
2824 2012-08-27 Jan Djärv <jan.h.d@swipnet.se>
2826 * nsterm.h (NSPanel): New class variable dialog_return.
2828 * nsmenu.m (initWithContentRect:styleMask:backing:defer:):
2829 Initialize dialog_return.
2830 (windowShouldClose:): Use stop instead of stopModalWithCode.
2831 (clicked:): Ditto, and also set dialog_return (Bug#12258).
2832 (timeout_handler:): Use stop instead of abortModal. Send a dummy
2834 (runDialogAt:): Make ret Lisp_Object. Set it from dialog_return when

2878 * fileio.c (Finsert_file_contents):
2879 Use bool for booleans.
2880 * coding.h, lisp.h: Reflect above API changes.
2881 * coding.c: Remove unnecessary static function decls.
2882 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
2883 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
2884 not a boolean 'int', since callers never look at the return value.
2885 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
2886 * coding.h (decoding_buffer_size, encoding_buffer_size)
2887 (emacs_mule_string_char): Remove unused extern decls.
2888 (struct iso_2022_spec, struct coding_system):
2889 Use 'unsigned int : 1' for boolean fields, since there's more than one.
2890 (struct emacs_mule_spec): Remove unused field 'full_support'.
2891 All initializations removed.
2892 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
2894 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
2896 Fix spare memory change (Bug#12286).
2897 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
2898 (valid_lisp_object_p): Likewise.
2900 2012-08-27 Martin Rudalics <rudalics@gmx.at>
2902 * window.c (Fset_window_configuration): Record any window's old
2903 buffer if it's replaced (see Bug#8789). If the new current
2904 buffer doesn't appear in the selected window, go to its old
2907 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
2909 Special MEM_TYPE_SPARE to denote reserved memory.
2910 * alloc.c (enum mem_type): New memory type.
2911 (refill_memory_reserve): Use new type for spare memory.
2912 This prevents live_cons_p and live_string_p from incorrect
2913 detection of uninitialized objects from spare memory as live.
2915 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
2918 * Makefile.in (.PHONY): versioclean -> versionclean.
2920 Remove unused external symbols.
2921 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
2922 * window.c (Qwindow_valid_p, decode_valid_window):
2923 Now static, not extern.
2924 * data.c (Qinterval): Remove; unused.
2925 (syms_of_data): Do not define 'interval'.
2926 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
2927 * window.h (decode_valid_window):
2930 * character.c, charset.c, chartab.c: Use bool for booleans.
2931 * character.c (lisp_string_width, string_count_byte8)

2940 (char_table_set_range, optimize_sub_char_table)
2941 (map_sub_char_table):
2942 Use bool for boolean.
2943 * character.c (str_to_unibyte): Omit last boolean argument; it was
2944 always 0. All callers changed.
2945 * character.h, charset.h: Adjust to match previous changes.
2946 * character.h (char_printable_p): Remove decl of nonexistent function.
2947 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
2948 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
2949 are all boolean, so make them single-bit bitfields.
2951 * lisp.h (ASET): Remove attempt to detect side effects.
2952 It was meant to be temporary and it often doesn't work,
2953 because when IDX has side effects the behavior of IDX==IDX
2954 is undefined. See Stefan Monnier in
2955 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
2957 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
2959 * lisp.h (functionp): New function (extracted from Ffunctionp).
2960 (FUNCTIONP): Use it.
2961 * eval.c (Ffunctionp): Use it.
2963 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
2965 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
2966 as that's faster and simpler than static storage. Don't bother
2967 with the g_main_context_query overhead if g_main_context_pending
2968 says no events are pending.
2969 (gfds, gfds_size): Remove these static vars.
2970 (xgselect_initialize): Remove; no longer needed.
2971 All uses and decls removed.
2973 * emacs.c (fatal_error_signal_hook): Remove.
2974 All uses removed. This leftover from old code was always 0.
2976 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
2977 * casefiddle.c (casify_object, casify_region):
2978 * casetab.c (set_case_table):
2979 * category.c, category.h (word_boundary_p):
2980 * category.h (CHAR_HAS_CATEGORY):
2981 Use bool for booleans, instead of int.
2983 2012-08-25 Eli Zaretskii <eliz@gnu.org>
2985 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
2987 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
2989 On assertion failure, print backtrace if available.
2990 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
2991 (die) [ENABLE_CHECKING]: Print a backtrace if available.
2992 * Makefile.in (LIB_EXECINFO): New macro.
2995 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
2996 * bytecode.c (exec_byte_code):
2997 * callint.c (check_mark, Fcall_interactively):
2998 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
2999 (getenv_internal, sync_process_alive, call_process_exited):
3000 * lisp.h (USE_SAFE_ALLOCA):
3001 Use bool for booleans, instead of int.
3002 * lisp.h, process.h: Adjust prototypes to match above changes.
3003 * callint.c (Fcall_interactively): Don't assume the mark's
3004 offset fits in 'int'.
3006 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
3008 * buffer.c, buffer.h: Use bool for boolean.
3009 * buffer.c (reset_buffer_local_variables)

3014 (report_overlay_modification, call_overlay_mod_hooks):
3015 (mmap_enlarge, mmap_set_vars):
3016 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
3017 Use bool for booleans, instead of int.
3018 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
3019 since the 1-or-0 return value is always ignored anyway.
3020 (mmap_initialized_p):
3021 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
3022 * buffer.h, lisp.h: Adjust prototypes to match above changes.
3024 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
3026 * bidi.c: Use bool for boolean.
3027 This is a bit more readable, and makes the text segment of bidi.o
3028 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
3029 Presumably it's faster too.
3030 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
3032 (bidi_cache_find_level_change, bidi_cache_iterator_state)
3033 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
3034 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
3035 (bidi_explicit_dir_char, bidi_level_of_next_char)
3036 (bidi_find_other_level_edge, bidi_move_to_visually_next):
3037 Use bool for booleans, instead of int.
3038 * dispextern.h (bidi_init_it, bidi_paragraph_init)
3039 (bidi_unshelve_cache): Adjust decls to match code.
3041 2012-08-23 Martin Rudalics <rudalics@gmx.at>
3043 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
3046 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
3048 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
3049 * atimer.h: Include <stdbool.h>.
3051 2012-08-22 Dan Nicolaescu <dann@gnu.org>
3053 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
3054 compile time tests instead of run time tests on systems that do
3056 (FRAME_MAC_P): Remove leftover from deleted code.
3057 * frame.c (syms_of_frame): Remove leftover from deleted code.
3059 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
3061 * nsterm.m (insertText:): Don't clear modifiers if code is space.
3063 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
3065 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
3066 Otherwise, the compiler complains about (A?B:C) where B is void
3067 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
3068 (fontset_add): Return void, for FONTSET_ADD.
3070 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
3072 * alloc.c: Use bool for booleans.
3073 (gc_in_progress, abort_on_gc)
3074 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
3075 (dont_register_blocks) [GC_MALLOC_CHECK]:
3076 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
3077 (check_string_bytes, make_specified_string, memory_full)
3078 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
3079 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
3080 (mark_stack, valid_pointer_p, make_pure_string)
3081 (Fgarbage_collect, survives_gc_p, gc_sweep):
3082 Use bool for booleans, instead of int.
3083 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
3084 Remove unused local.
3085 * alloc.c (PURE_POINTER_P):
3086 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
3087 * editfns.c (Fformat):
3088 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
3090 * fns.c (sweep_weak_table):
3091 * lisp.h (suppress_checking, push_message, survives_gc_p)
3092 (make_pure_string, gc_in_progress, abort_on_gc):
3093 * lread.c (readchar, read1):
3094 * print.c (Fprin1_to_string):
3095 * xdisp.c (push_message):
3096 Use bool for booleans affected directly or indirectly by
3099 Make recently-introduced setters macros.
3100 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
3101 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
3102 (set_fontset_default, set_fontset_fallback): Rename from their
3103 upper-case counterparts, and make them functions rather than macros.
3104 This is more consistent with the other recently-introduced setters.
3105 These don't need to be inline, since they're local.
3107 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
3109 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
3110 the loop (Bug#12247).
3112 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
3114 * lisp.h (vcopy): Use memcpy rather than our own loop.
3115 This fixes a performance regression introduced by the recent
3116 addition of vcopy. This means 'vcopy' will need to be modified
3117 for a copying collector, but that's OK. Also, tighten the
3118 checking in the assertion.
3120 2012-08-21 Eli Zaretskii <eliz@gnu.org>
3122 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
3123 components for RTL text (Bug#11860). Adjust X-OFFSET of each
3124 non-base glyph for the width of the base character, according to
3125 what x_draw_composite_glyph_string_foreground expects.
3126 Generate WADJUST value according to composition_gstring_width's
3127 expectations, to produce correct width of the composed character.
3128 Reverse the sign of the DU offset produced by ScriptPlace.
3130 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
3132 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
3134 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
3136 Avoid direct writes to contents member of struct Lisp_Vector.
3137 * lisp.h (vcopy): New function to copy data into vector.
3138 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
3139 * fns.c (Ffillarray): Use ASET.
3140 * keyboard.c (timer_check_2): Use AREF and ASET.
3141 (append_tool_bar_item, Frecent_keys): Use vcopy.
3142 * lread.c (read_vector): Use ASET.
3143 * msdos.c (Frecent_doskeys): Use vcopy.
3144 * xface.c (Finternal_copy_lisp_face): Use vcopy.
3145 (Finternal_merge_in_global_face): Use ASET and vcopy.
3146 * xfont.c (xfont_list_pattern): Likewise.
3148 2012-08-21 Martin Rudalics <rudalics@gmx.at>
3150 * window.c (Fwindow_point): For the selected window always return
3151 the position of its buffer's point.
3152 (Fset_window_point): For the selected window always go in its
3153 buffer to the specified position.
3155 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
3157 Setter macros for fontsets.
3158 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
3159 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
3160 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
3163 2012-08-20 Glenn Morris <rgm@gnu.org>
3165 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
3166 Don't assume that `ln -f' works.

3196 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
3197 (set_hash_hash, set_hash_index): Rename with _slot suffix.

3212 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
3214 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
3216 Rely on <config.h> + <unistd.h> to declare 'environ',
3217 as gnulib does this if the system doesn't.
3218 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
3219 Remove declaration. MS-Windows declares it on stdlib.h which is

3253 * chartab.c, lisp.h (char_table_set, char_table_set_range):
3254 Return void, not Lisp_Object. Otherwise, the compiler
3255 complains about (A?B:C) where B is void and C is Lisp_Object

4087 2012-08-04 Eli Zaretskii <eliz@gnu.org>
4089 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
4090 * w32.c (init_environment): Change the default values of many
4091 environment variables in dflt_envvars[] to NULL, to avoid pushing
4092 them into environment when they were not already defined.
4093 Remove the code that deletes site-lisp subdirectories from the default
4094 value of EMACSLOADPATH, as it is no longer needed.
4095 (check_windows_init_file): Now external, not static.
4096 Use Vload_path as is, without adding anything, as this function is now
4097 called when Vload_path is already set up.
4099 * w32.h (check_windows_init_file): Add prototype.
4101 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build
4102 directory, ignore the /*/i386/ tail in Vinvocation_directory, for
4103 compatibility with Posix platforms.
4104 (main): Move the call to check_windows_init_file to here from
4106 (decode_env_path) [WINDOWSNT]: Expand the %emacs_dir%/ prefix, if
4107 any, in the DEFALT argument into the root of the Emacs build or
4108 installation tree, as appropriate.
4110 * callproc.c (init_callproc_1): Call decode_env_path instead of
4111 doing its equivalent by hand.
4112 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
4113 the code that sets Vexec_path run on MS-Windows.
4115 * lread.c (init_lread): Add comments to #ifdef's.
4117 * msdos.c (dos_set_window_size, IT_update_begin)
4118 (IT_frame_up_to_date, IT_set_frame_parameters): Use FVAR and WVAR
4119 instead of direct references.

4124 * lisp.h (DEFAULT_REHASH_THRESHOLD, DEFAULT_REHASH_SIZE):
4125 Now constants, not macros.
4127 2012-08-03 Paul Eggert <eggert@cs.ucla.edu>
4129 Remove unnecessary casts involving pointers.
4130 These casts are no longer needed now that we assume C89 or later,
4131 since they involve casting to or from void *.
4132 * alloc.c (make_pure_string, make_pure_c_string, pure_cons)
4133 (make_pure_float, make_pure_vector):
4134 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP):

4143 (x_get_window_property, x_get_window_property_as_lisp_data):
4144 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
4145 Remove unnecessary pointer casts.
4146 * alloc.c (record_xmalloc): New function.
4147 * lisp.h (record_xmalloc): New decl.
4148 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
4149 more like a function. This is because the pointer cast is not
4150 needed. All uses changed.
4151 * print.c (print_string, print_error_message): Avoid length recalc.
4153 Improve fix for macroexp crash with debugging (Bug#12118).
4154 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
4155 ARRAY_MARK_FLAG when checking subscripts, because ASET is
4156 not supposed to be invoked from the garbage collector.
4157 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
4158 (gc_aset): New function, which is like ASET but can be
4159 used in the garbage collector.
4160 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)

4170 <g_b_init_create_symbolic_link>: New static flags.
4171 (globals_of_w32): Initialize them to zero.
4172 (GetSecurityInfo_Proc, CreateSymbolicLink_Proc): New typedefs.
4173 (map_w32_filename): Improve commentary. Simplify switch.
4174 (SYMBOLIC_LINK_FLAG_DIRECTORY): Define if not defined in system
4175 headers (most versions of MinGW w32api don't).
4176 (get_security_info, create_symbolic_link)
4177 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
4179 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
4180 in the argument file name.

4183 (sys_rename): Diagnose renaming of a symlink when the user doesn't
4184 have the required privileges.
4185 (get_file_security_desc_by_name): Rename from
4186 get_file_security_desc.
4187 (stat_worker): New function, with most of the guts of 'stat', and
4188 with addition of handling of symlinks and support for 'lstat'.
4189 If possible, get file's attributes and security information by
4190 handle, not by name. Produce S_IFLNK bit for symlinks, when
4191 called from 'lstat'.
4192 (stat, lstat): New functions, call 'stat_worker'.
4193 (symlink, readlink, careadlinkat): Rewritten to create and resolve
4194 symlinks when the underlying filesystem supports them.
4196 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
4198 Fix macroexp crash on Windows with debugging (Bug#12118).
4199 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
4200 checking subscripts; problem introduced with the recent
4201 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
4202 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
4203 since it's used in non-static inline functions now.
4205 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
4206 Don't assume buffer size fits in 'int'. Remove unused local.
4208 Use C99-style 'extern inline' if available.

4220 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
4221 * alloc.c (LISP_INLINE):

4223 * category.c (CATEGORY_INLINE):
4224 * character.c (CHARACTER_INLINE):
4225 * charset.c (CHARSET_INLINE):
4226 * composite.c (COMPOSITE_INLINE):
4227 * dispnew.c (DISPEXTERN_INLINE):
4228 * sysdep.c (SYSTIME_INLINE):
4229 Define to EXTERN_INLINE, so that the corresponding functions
4230 are compiled into code.
4231 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
4232 (INLINE_HEADER_END): New macros.
4233 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

4253 hard-coding the path separator.
4255 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
4257 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
4258 This how ASET and AREF are supposed to work, and makes
4259 it easier to think about future improvements. See
4260 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
4261 * charset.h (set_charset_attr): New function.
4262 All lvalue-style uses of CHARSET_DECODER etc. changed to use it.
4263 * lisp.h (ASET): Rewrite so as not to use AREF in an lvalue style.

4515 does that unconditionally. Remove file, which is now empty.
4517 * s/freebsd.h, s/gnu-linux.h, s/sol2-6.h, s/unixware.h:
4520 2012-07-30 Paul Eggert <eggert@cs.ucla.edu>
4522 Export to GDB most of lisp.h's remaining object-like macros.

4535 (CHAR_TABLE_STANDARD_SLOTS, CHAR_TABLE_EXTRA_SLOTS):
4536 Move to after the definition of struct Lisp_Char_Table,
4537 since the former now needs that type defined.

4638 * w32inevt.c: Include w32inevt.h.
4639 (w32_read_console_input): New inline function, calls either
4640 ReadConsoleInputA or ReadConsoleInputW, depending on the value of
4641 w32_console_unicode_input.
4642 (fill_queue): Call w32_read_console_input instead of ReadConsoleInput.
4643 (w32_kbd_patch_key, key_event): Use the codepage returned by
4644 GetConsoleCP, rather than the ANSI codepage returned by GetLocaleInfo.
4645 (key_event): use uChar.UnicodeChar only if
4646 w32_console_unicode_input is non-zero.

4676 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
4677 enumeration constants, as PURE and HEAP are too general, and clash
4678 with other headers and sources, such as gmalloc.c and the
4679 MS-Windows system headers. All users changed.
4681 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
4683 Revert last save_excursion_save and save_excursion_restore changes.
4684 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

4694 2012-07-27 Paul Eggert <eggert@cs.ucla.edu>
4696 Improve GDB symbol export (Bug#12036).
4697 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
4698 arms of an 'if', not using conditional expressions; otherwise GDB
4699 complains about the types in the unevaluated arm when the argument
4700 is an integer literal.
4701 (xgetint): Simplify expression.
4702 * alloc.c (gdb_make_enums_visible): New constant. This ports to
4703 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
4704 Zaretskii in <http://bugs.gnu.org/12036#13>.
4705 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
4706 needed now that we have gdb_make_enums_visible.
4707 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
4708 (enum enum_USE_LSB_TAG):
4709 New enum types, packaging up enums that need to be exported to GDB.

4728 * xfns.c (syms_of_xfns): Likewise.
4730 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
4732 Fast save_excursion_save and save_excursion_restore.
4733 * lisp.h (struct Lisp_Excursion): New data type.
4734 (PVEC_EXCURSION): New pseudovector type.
4735 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
4736 to deal with it. Adjust comments.

4750 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
4751 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
4752 emacs.c, as this is a more-suitable home. Had this been done earlier
4753 the fix for 12036 would have avoided some of the problems noted in
4754 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
4755 would have been more obvious.
4756 * emacs.c: Do not include <verify.h>; no longer needed.
4757 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
4758 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
4759 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):

4765 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
4766 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
4767 not be usable in #if. This simplifies things.
4769 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
4771 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
4773 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

4776 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
4777 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
4778 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
4779 Adjust to changes in lisp.h and emacs.c, by using
4780 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
4781 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
4782 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
4783 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
4784 instead of gdb_valbits.
4785 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
4786 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
4787 instead of gdb_array_mark_flag.
4788 (xboolvector): Get size from $->size, not $->header.size.
4789 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
4790 (xreload, hook-run, hookpost-run): Remove.
4791 * emacs.c: Include <verify.h>.
4792 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
4793 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
4795 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
4796 (gdb_USE_LSB_TAG): New enum constants.
4797 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
4798 Also define these as enum constants, so they're visible to GDB.
4799 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
4800 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
4801 as constants, so they're visible to GDB.
4802 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
4803 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
4804 Now enum constants, not macros, so they're visible to GDB.
4805 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
4806 more convenient now. All uses changed.
4807 (VALMASK) [USE_LSB_TAG]: Also define in this case.
4808 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
4810 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

4815 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
4817 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
4818 add argument, tune behavior, and adjust all callers.
4820 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
4822 Use typedef for EMACS_INT, EMACS_UINT.
4823 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
4824 than macros. This simplifies debugging in the usual case, since
4825 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
4826 and it allows expressions involving EMACS_INT casts.
4827 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
4829 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

4839 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
4841 Adjust buffer text indirection counters at the end of Fkill_buffer.
4842 * buffer.c (Fkill_buffer): Adjust indirection counters when the
4843 buffer is definitely dead. This should really fix an issue reported
4844 by Christoph Scholtes again. (Bug#12007).
4845 (init_buffer_once): Initialize indirection counters of
4846 buffer_defaults and buffer_local_symbols (for sanity and safety).
4848 2012-07-24 Eli Zaretskii <eliz@gnu.org>
4850 * xdisp.c (init_iterator): Don't compute dimensions of truncation
4851 and continuation glyphs on tooltip frames, leave them at zero.
4852 Avoids continued lines in tooltips. (Bug#11832)
4854 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
4856 Simplify copy_overlay.
4857 * buffer.c (copy_overlay): Simplify. Use build_marker.

4863 or invalid. (Bug#12025)
4865 * window.c (decode_any_window): Disable CHECK_LIVE_FRAME test, as
4866 it signals an error when a tooltip frame is being created.
4868 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
4870 Cleanup miscellaneous objects allocation and initialization.
4871 * alloc.c (allocate_misc): Change to static. Add argument to
4872 specify the subtype. Adjust comment and users.
4873 (build_overlay): New function.
4874 * buffer.c (copy_overlays, Fmake_overlay): Use it.
4875 * lisp.h (struct Lisp_Overlay): Remove obsolete comment.
4876 (allocate_misc): Remove prototype.
4877 (build_overlay): Add prototype.
4879 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
4881 Swap buffer text indirection counters in Fbuffer_swap_text.
4882 * buffer.c (Fbuffer_swap_text): Swap indirections too.
4883 This avoids crash reported by Christoph Scholtes at
4884 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
4886 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
4888 * nsmenu.m (Popdown_data): New struct.
4889 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
4891 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
4892 (initWithContentRect): Make imgView and contentView non-static
4893 and autorelease them. Also autorelease img and matrix (Bug#12005).
4894 (dealloc): Remove (Bug#12005).
4896 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
4898 Adjust consing_since_gc when objects are explicitly freed.
4899 * alloc.c (GC_DEFAULT_THRESHOLD): New macro.
4900 (Fgarbage_collect): Use it. Change minimum to 1/10 of default.
4901 (free_cons, free_misc): Subtract object size from consing_since_gc.
4903 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>

4907 (live_buffer, set_marker_internal): New function.
4908 (Fset_marker, set_marker_restricted): Use set_marker_internal.
4909 (set_marker_both, set_marker_restricted_both): Use live_buffer.
4911 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
4913 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
4914 as it's limited by the amount of memory, not by INT_MAX.
4916 2012-07-21 Eli Zaretskii <eliz@gnu.org>
4918 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
4919 in special-event-map. See the discussion at
4920 http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00417.html

5642 * s/aix4-2.h (unix): Remove; no longer needed.
5644 EMACS_TIME simplification (Bug#11875).
5645 This replaces macros (which typically do not work in GDB)

5647 The functional style also makes code easier to read and maintain.
5648 * systime.h: Include <sys/time.h> on all hosts, not just if
5649 WINDOWSNT, since 'struct timeval' is needed in general.

5665 (add_emacs_time, sub_emacs_time): New functions.
5666 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.

5689 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
5690 Prefer snprintf to strncpy.
5691 * nsterm.m (ns_term_init):
5692 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
5693 * nsterm.m (ns_term_init):
5694 Avoid the need for strncpy, by using build_string or
5695 make_unibyte_string directly. Use dtoastr, not snprintf.
5696 * process.c (Fmake_network_process): Diagnose service names that
5697 are too long, rather than silently truncating them or creating
5698 non-null-terminated names.
5699 (Fnetwork_interface_info): Likewise, for interface names.

5715 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
5716 where argument type is known to be a Lisp_Cons.

5771 O_RDONLY already includes it).
5773 Stop ns builds setting the EMACSLOADPATH environment variable.
5774 * nsterm.m (ns_load_path): Rename from ns_init_paths.
5775 Now it does not set EMACSLOADPATH, just returns the load-path string.
5776 * nsterm.h: Update accordingly.
5777 * lread.c [HAVE_NS]: Include nsterm.h.
5778 (init_lread) [HAVE_NS]: Use ns_load_path.

5788 (ns_init_paths): Do not set EMACSPATH.
5789 * nsterm.h (ns_exec_path): Add it.

5842 * nsterm.h (ns_etc_directory): Add it.
5843 * callproc.c [HAVE_NS]: Include nsterm.h.
5844 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
5846 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
5848 Move marker debugging code under MARKER_DEBUG.
5849 * marker.c (MARKER_DEBUG): Move marker debugging code under
5850 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
5851 for bootstrap with --enable-checking (~3x slowdown reported
5852 by Juanma Barranquero <lekktu@gmail.com>).
5853 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
5855 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
5857 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
5858 See <http://bugs.gnu.org/11825#29>.
5860 2012-07-08 Eli Zaretskii <eliz@gnu.org>
5862 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
5863 has no font, use the frame's font. (Bug#11813)
5864 (display_line): Add commentary about displaying truncation glyphs
5866 (produce_special_glyphs): Move here from term.c.
5868 * term.c (produce_special_glyphs): Move to xdisp.c.
5870 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
5873 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
5875 * xdisp.c (display_line): Avoid warning about implicit declaration
5878 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
5880 * lisp.h: Remove empty conditional.
5882 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
5884 * lread.c (load_path_check): Now static.
5886 Fix some minor --with-ns problems found by static checking.
5887 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
5888 (x_set_font) [!HAVE_X_WINDOWS]:
5889 * image.c (xpm_load_image) [HAVE_NS]:
5890 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
5891 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
5892 Remove unused local.
5893 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
5894 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
5895 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
5896 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
5897 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
5898 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
5899 Fix pointer signedness problem.
5900 * xfaces.c (FRAME_X_FONT_TABLE):
5901 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
5903 2012-07-07 Glenn Morris <rgm@gnu.org>
5905 * lread.c (load_path_check): New function, split from init_lread.
5906 (init_lread): Reorganize. Motivation:
5907 If EMACSLOADPATH is set, check/warn about that rather than the
5908 defaults, which we are not going to use. Hence we can remove
5909 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
5910 Don't warn if site-lisp directories are missing.
5911 If not installed, start from a blank load-path, since
5912 PATH_LOADSEARCH refers to the eventual installation directories.
5914 2012-07-07 Eli Zaretskii <eliz@gnu.org>
5916 Support truncation and continuation glyphs on GUI frames, when
5917 fringes are disabled. (Bug#11832)
5918 * xdisp.c (init_iterator): Get dimensions of truncation and
5919 continuation glyphs even if on GUI frames.
5920 Adjust it->last_visible_x on GUI frames when the left or right fringes,
5921 or both, are absent.
5922 (start_display, move_it_in_display_line_to): Handle the case of a
5923 GUI frame without a fringe to display continuation or truncation
5925 (insert_left_trunc_glyphs): Support GUI frames: make sure
5926 truncation glyphs overwrite enough glyphs from the current line to
5927 have sufficient space in pixels.
5928 (display_line): Support truncation and continuation glyphs on GUI
5929 frames. If some spare pixels are left on the line after inserting
5930 the truncation glyphs, fill that space with a stretch glyph of a
5931 suitably computed width.
5933 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
5934 produce_glyphs, to support GUI sessions.
5936 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
5938 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
5940 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
5942 Do not require float-time's arg to fit in time_t (Bug#11825).
5943 This works better on hosts where time_t is unsigned, and where
5944 float-time is applied to the (negative) difference between two times.
5945 * editfns.c (decode_time_components): Last arg is now double *,
5946 not int *, and means to store all the result as a double, without
5947 worrying about whether the seconds part fits in time_t.
5948 All callers changed.
5949 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
5950 All callers changed.
5951 (Ffloat_time): Do not fail merely because the specified time falls
5952 outside of time_t range.
5954 2012-07-07 Glenn Morris <rgm@gnu.org>
5956 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

5963 Update dependencies.
5965 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
5967 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
5969 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).

5971 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
5972 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
5973 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
5974 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
5976 * xfont.c (compare_font_names): Redo to omit the need for casts.
5978 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
5980 * xfns.c (Fx_change_window_property): Doc fix.
5981 * w32fns.c (Fx_change_window_property): Doc fix.
5983 * w32fns.c (Fx_window_property): Accept the same arguments as the
5984 X Windows version. Doc fix.
5985 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
5987 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
5988 Eli Zaretskii <eliz@gnu.org>
5990 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
5991 Windows-specific code from nt/config.nt moved here.
5992 Obsolete settings removed.
5994 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
5996 * process.c: Avoid unnecessary calls to gettime.
5997 (wait_reading_process_output): Don't get the time of day
5998 when gobbling data immediately and not waiting, as there's no need
5999 for it in that case. This removes a FIXME.
6001 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
6003 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
6004 is defined (Bug#11768).
6006 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6008 Fix marker debugging code.
6009 * marker.c (byte_char_debug_check): Do not perform the check
6010 if buffer is not multibyte.
6011 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
6012 Call byte_char_debug_check with correct arguments.
6014 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6016 Compile marker debugging code only if ENABLE_CHECKING is defined.
6017 * marker.c (byte_char_debug_check, count_markers):
6018 Use only if ENABLE_CHECKING is defined.
6019 (byte_debug_flag): Remove.
6020 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
6021 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
6023 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6025 Avoid code repetition in marker-related functions.
6026 * marker.c (attach_marker): New function.
6027 (Fset_marker, set_marker_restricted, set_marker_both)
6028 (set_marker_restricted_both): Use it.
6029 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
6030 Consistently rename charno to charpos.
6031 (marker_position): Add eassert.
6032 (marker_byte_position): Convert to eassert.

6044 * lisp.h (build_marker): New prototype.
6045 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
6046 * composite.c (autocmp_chars): Likewise.
6047 * editfns.c (buildmark): Remove.
6048 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
6049 (save_restriction_save): Use build_marker.
6050 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
6051 * window.c (save_window_save): Likewise.
6053 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6055 Do not use Fdelete_overlay in delete_all_overlays
6056 to avoid redundant calls to unchain_overlay.
6057 * buffer.c (drop_overlay): New function.
6058 (delete_all_overlays, Fdelete_overlay): Use it.
6059 * minibuf.c (get_minibuffer): Fix comment.
6061 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
6063 Port to OpenBSD 5.1 amd64.
6064 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
6065 This is needed for OpenBSD, and should be harmless on all BSD systems.
6066 Also, include <sys/sysctl.h>, as it should be available on all
6067 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
6068 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
6069 use p_pid member, not kp_proc.pid.
6071 2012-07-06 Glenn Morris <rgm@gnu.org>
6073 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
6075 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
6077 More xmalloc and related cleanup.
6078 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
6079 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:

6084 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:
6085 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
6086 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
6088 Omit needless casts involving void * pointers and allocation.
6089 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
6090 as the former is more robust if P's type is changed.
6091 Prefer xzalloc to xmalloc + memset 0.
6092 Simplify malloc-or-realloc to realloc.
6093 Don't worry about xmalloc returning a null pointer.
6094 Prefer xstrdup to xmalloc + strcpy.
6095 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
6097 * keyboard.c (apply_modifiers_uncached): Prefer local array to
6098 alloca of a constant.
6100 2012-07-05 Eli Zaretskii <eliz@gnu.org>
6102 * xdisp.c (display_line): Fix horizontal pixel coordinates when
6103 hscroll is larger than the line width. Fixes long and futile
6104 looping inside extend_face_to_end_of_line (on a TTY) producing
6105 glyphs that are not needed and thrown away.
6107 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
6109 * marker.c (set_marker_restricted_both): Simplify by using
6112 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
6114 * editfns.c (region_limit): Simplify by using clip_to_bounds.

6121 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
6122 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
6123 followed by gtk_box_set_homogeneous (Bug#11768).
6124 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
6125 (update_theme_scrollbar_width, xg_create_scroll_bar):
6126 Use gtk_scrollbar_new (Bug#11768).
6127 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
6128 (is_box_type): New function (Bug#11768).
6129 (xg_tool_item_stale_p): Call is_box_type.
6130 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
6131 with default display (Bug#11768).
6133 2012-07-05 Eli Zaretskii <eliz@gnu.org>
6135 * xdisp.c (window_hscroll_limited): New function.
6136 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
6137 coordinates when window's hscroll is set to insanely large
6140 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
6142 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
6143 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
6145 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
6148 * lisp.h (xzalloc): New prototype. Omit needless casts.

6204 Problem reported by Troels Nielsen in
6205 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
6207 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
6209 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
6210 This should be fixed in a better way; see Eli Zaretskii in
6211 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
6212 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
6214 * fileio.c (time_error_value): Rename from special_mtime.
6215 The old name's problems were noted by Eli Zaretskii in
6216 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
6218 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
6219 This variable's comment says Emacs needs at least one GDB-visible
6220 symbol of type enum pvec_type, to work around GDB problems.
6221 The symbol's value doesn't matter.
6223 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
6224 that causes compilation to fail on pre-C99 compilers.
6226 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
6228 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
6229 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
6231 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
6233 * buffer.c (init_buffer_once): Fix initialization of
6234 headers for buffer_defaults and buffer_local_symbols.
6235 Reported by Juanma Barranquero <lekktu@gmail.com>.
6237 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
6239 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
6240 * lisp.h (enum pvec_type): Use fewer bits.
6241 (PSEUDOVECTOR_SIZE_BITS): New constant.
6242 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
6243 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
6244 change in pvec_type.
6245 (PSEUDOVECTOR_TYPEP): New macro.
6246 (TYPED_PSEUDOVECTORP): Use it.
6247 * fns.c (internal_equal): Adapt code to extract pvectype.
6248 * emacs.c (gdb_pvec_type): Update type.
6249 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
6250 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
6251 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
6252 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
6253 (sweep_vectors): Use it. Use local var `total_bytes' instead of
6254 abusing vector->header.next.nbytes.
6255 (live_vector_p): Use PVEC_TYPE.
6256 (mark_object): Adapt code to extract pvectype. Use switch.
6258 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
6260 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
6261 Tighten new eassert a bit.
6263 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
6265 Fix compilation with --enable-gcc-warnings and -O1
6267 * doprnt.c (doprnt): Change type of tem to int, initialize
6268 to avoid compiler warning. Add eassert.
6269 * search.c (simple_search): Initialize match_byte to avoid
6270 compiler warning. Add eassert.
6272 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
6274 Avoid weird behavior with large horizontal scrolls.
6275 Without this change, for example, large hscroll values would
6276 mess up Emacs's display on Fedora 15 x86, presumably due to
6277 overflows in int calculations in the display code.
6278 Also, if buffers had long lines, Emacs would freeze.
6279 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
6280 (set_window_hscroll): New function, containing the old guts of
6281 Fset_window_hscroll. Return the clipped value.
6282 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
6283 This avoids the need to check against PTRDIFF_MAX.
6285 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
6287 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
6289 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
6291 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
6293 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
6294 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
6295 since GCC 4.4.6 issues a bogus warning for them.
6297 Fix bugs in file timestamp newness comparisons.
6298 * fileio.c (Ffile_newer_than_file_p):
6299 * lread.c (Fload): Use full timestamp resolution of files,
6300 not just the 1-second resolution, so that files that are only
6301 slightly newer still count as newer.
6302 * fileio.c (Ffile_newer_than_file_p): Don't assume file
6303 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
6305 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
6307 * fileio.c: Improve handling of file time marker. (Bug#11852)
6308 (special_mtime): New function.
6309 (Finsert_file_contents, Fverify_visited_file_modtime):
6310 Use it to set special mtime values consistently.
6312 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
6314 * fileio.c (Finsert_file_contents): Properly handle st_mtime
6315 marker for non-existing file. (Bug#11852)
6317 2012-07-03 Glenn Morris <rgm@gnu.org>
6319 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
6320 and did not make it into globals.h).
6322 2012-07-03 Tom Tromey <tromey@redhat.com>
6324 * window.c (Fset_window_margins, Fset_window_fringes)
6325 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.

6368 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
6369 values which aren't power of 2.
6370 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
6371 Verify it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
6374 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
6376 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
6378 * alloc.c (mark_object): Revert part of last patch to use `switch'.
6380 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
6382 * alloc.c (allocate_vector_block): Remove redundant
6383 calls to mallopt if DOUG_LEA_MALLOC is defined.
6384 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
6385 avoid calls to mallopt if zero_vector is returned.
6387 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
6389 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
6390 is enabled, avoid dereferencing NULL current_sblock if
6393 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
6395 Cleanup basic buffer management.
6396 * buffer.h (struct buffer): Change layout to use generic vector
6397 marking code. Fix some comments. Change type of 'clip_changed'
6398 to bitfield. Remove unused #ifndef old.
6399 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
6400 (GET_OVERLAYS_AT): Fix indentation.
6401 (for_each_per_buffer_object_at): New macro.
6402 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
6403 (Fbuffer_local_variables): Use it.
6404 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
6405 * alloc.c (allocate_buffer): Adjust to match new layout of
6406 struct buffer. Fix comment.
6407 (mark_overlay): New function.
6408 (mark_buffer): Use it. Use mark_vectorlike to mark normal
6409 Lisp area of struct buffer.
6410 (mark_object): Use it. Adjust marking of misc objects
6411 and related comments.
6413 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
6415 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
6416 wrapper that is not needed because the wrapped code is a no-op (zero
6417 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
6418 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
6420 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
6422 * alloc.c (mark_buffer): Simplify. Remove prototype.
6423 (mark_object): Add comment. Reorganize marking of vector-like
6424 objects. Use CHECK_LIVE for all vector-like objects except buffers
6425 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
6426 Avoid redundant calls to mark_vectorlike for bool vectors.
6428 2012-06-30 Glenn Morris <rgm@gnu.org>
6430 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
6432 * epaths.in (PATH_SITELOADSEARCH): New.
6433 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
6434 This is rather than relying on --enable-locallisppath elements
6435 having "site-lisp" in their names. (Bug#10208#25, 11658)
6437 2012-06-30 Eli Zaretskii <eliz@gnu.org>
6439 * w32proc.c (sys_select): Accept and ignore one more argument.
6441 * w32.c (emacs_gnutls_pull): Call select with one more argument.
6443 * sysselect.h [DOS_NT]: Don't include sys/select.h.
6444 (pselect) [!MS_DOS]: Redirect to sys_select.
6446 * sysdep.c: Don't include dos.h and dosfns.h.
6448 * process.c (sys_select):
6449 * msdos.c (sys_select): Accept one more argument and ignore it.
6451 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
6452 adapt data types and code to that.
6455 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
6456 which clashes with the gnulib function of the same name.
6458 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
6460 * font.c (font_style_to_value, font_style_symbolic)
6461 (font_prop_validate_style): Add type checks for values in
6464 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
6466 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
6469 2012-06-29 Eli Zaretskii <eliz@gnu.org>
6471 * xdisp.c (try_window_id): Undo last change.
6473 * w32.c (getwd): Adjust commentary about startup_dir.
6474 (init_environment): Always call sys_access, even in non-MSVC
6475 builds. Don't chdir to the directory of the Emacs executable.
6476 This undoes code from 1997 which was justified by the need to
6477 "avoid conflicts when removing and renaming directories". But its
6478 downside was that every relative file name was being interpreted
6479 relative to the directory of the Emacs executable, which can never
6480 be TRT. In particular, it broke sys_access when called with
6481 relative file names.
6482 (sys_access): Map GetLastError to errno.
6484 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
6486 * window.h (struct window): Change type of 'fringes_outside_margins'

6490 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
6493 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>

6496 Add QUIT to make the loop interruptible.
6498 2012-06-29 Glenn Morris <rgm@gnu.org>
6500 * charset.c (init_charset): Make lack of etc/charsets fatal.
6502 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
6504 * editfns.c (region_limit): Fix type mismatch.
6506 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
6508 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
6509 undefined. Convert from xassert to eassert.
6510 * nsmenu.m: Convert from xassert to eassert.
6511 * nsterm.m: Likewise.
6513 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>

6517 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
6519 Avoid integer overflow on scroll-left and scroll-right.
6520 * window.c (HSCROLL_MAX): New macro.
6521 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
6522 overflow when requested scroll falls outside ptrdiff_t range.
6524 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
6526 * window.h (struct window): Change type of 'hscroll',
6527 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
6528 'last_modified' and 'last_overlay_modified' to EMACS_INT.
6529 Adjust users accordingly.
6530 * xdisp.c (try_cursor_movement): Replace type check with eassert.
6531 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
6532 from EMACS_INT to ptrdiff_t.
6533 (make_window): Omit redundant initialization.
6535 2012-06-28 Juanma Barranquero <lekktu@gmail.com>

6539 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
6541 * window.h (struct window): Change type of 'use_time' and

6552 Fix GLYPH_DEBUG usage assuming that it may be undefined,
6553 adjust comments accordingly.

6608 * alloc.c (allocate_string): Omit intervals initialization.
6609 * alloc.c (make_uninit_multibyte_string): Initialize intervals
6610 as in make_pure_string and make_pure_c_string.
6612 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
6614 * alloc.c (allocate_string): Fix last change.
6616 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>

6666 * alloc.c: Remove build_string.
6667 * lisp.h: Define build_string as static inline. This provides
6668 a better opportunity to optimize away calls to strlen when the
6669 function is called with compile-time constant argument.
6670 * image.c (imagemagick_error): Convert to build_string.
6671 * w32proc.c (sys_spawnve): Likewise.
6672 * xterm.c (x_term_init): Likewise.
6674 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
6676 Use sprintf return value instead of invoking strlen on result.
6677 In the old days this wasn't portable, since some sprintf
6678 implementations returned char *. But they died out years ago and
6679 Emacs already assumes sprintf returns int.
6680 Similarly for float_to_string.
6681 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
6682 * ccl.c (ccl_driver):
6683 * character.c (string_escape_byte8):

6688 * xfns.c (syms_of_xfns):
6689 Use sprintf or float_to_string result to avoid need to call strlen.
6690 * data.c (Fnumber_to_string):
6691 Use make_unibyte_string, since the string must be ASCII.
6692 * lisp.h, print.c (float_to_string): Now returns int length.
6693 * term.c (produce_glyphless_glyph):
6694 Use sprintf result rather than recomputing it.
6696 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
6697 * Makefile.in (ALL_CFLAGS):
6698 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

6729 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

6734 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
6735 instead of truncating it to 63 (admittedly a generous limit).
6737 * process.c: Fix spelling and caps in comments.
6739 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>

6865 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
6867 Support higher-resolution time stamps (Bug#9000).
6868 The time stamps are only nanosecond-resolution at the C level,
6869 since that's the best that any real-world system supports now.
6870 But they are picosecond-resolution at the Lisp level, as that's
6871 easy, and leaves room for future OS improvements.
6873 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
6876 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
6877 Don't get current time unless it's needed.
6879 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
6880 now provides it if it's absent.
6881 (start_atimer): Port to higher-res time stamps.
6882 Check for time stamp overflow. Don't get current time more
6883 often than is needed.
6885 * buffer.h (struct buffer): Buffer modtime now has high resolution.
6886 Include systime.h, not time.h.
6887 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
6889 * dired.c: Include stat-time.h.
6890 (Ffile-attributes): File times now have higher resolution.

6893 (struct image): Timestamp now has higher resolution.
6895 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
6896 has at least microseconds now. All uses removed.
6897 (update_frame, update_single_window, update_window, update_frame_1)
6898 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
6899 (duration_to_sec_usec): Remove; no longer needed.
6901 * editfns.c (time_overflow): Now extern.

6907 (decode_time_components, lisp_seconds_argument): New functions.
6908 (make_time): Now static.
6909 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
6910 Report an error if the time is invalid, rather than having the caller
6913 * fileio.c: Include <stat-time.h>
6914 (Fcopy_file): Copy higher-resolution time stamps.
6915 Prefer to set the time stamp via a file descriptor if that works.

6917 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
6918 (Fvisited_file_modtime, Fset_visited_file_modtime):
6919 Support higher-resolution time stamps.
6921 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
6923 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
6925 * image.c (prepare_image_for_display, clear_image_cache)
6926 (lookup_image): Port to higer-resolution time stamps.
6928 * keyboard.c (start_polling, bind_polling_period):
6929 Check for time stamp overflow.
6930 (read_char, kbd_buffer_get_event, timer_start_idle)
6931 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
6932 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
6933 Port to higher-resolution time stamps. Do not assume time_t is signed.
6934 (decode_timer): New function. Timers are now vectors of length 9,
6935 not 8, to accommodate the picosecond component.
6936 (timer_check_2): Use it.
6938 * nsterm.m (select_timeout, timeval_subtract): Remove.
6939 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
6940 as they're a bit more accurate and handle overflow better.
6941 (ns_select): Change prototype to be compatible with pselect.
6942 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
6943 * nsterm.h (ns_select): Adjust prototype.
6945 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
6946 us-resolution time stamps.
6947 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
6949 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
6951 * lisp.h (time_overflow): New decl.
6952 (wait_reading_process_output): First arg is now intmax_t, not int,
6953 to accommodate larger waits.
6955 * process.h (struct Lisp_Process.read_output_delay):
6956 Now counts nanoseconds, not microseconds.
6957 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
6959 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
6960 (wait_reading_process_output):
6961 Port to ns-resolution time stamps.
6962 (Faccept_process_output, wait_reading_process_output):
6963 Check for time stamp overflow. Do not assume time_t is signed.
6964 (select_wrapper): Remove; we now use pselect.
6965 (Fprocess_attributes): Now generates ns-resolution time stamps.
6967 * sysdep.c: Include utimens.h. Don't include utime.h
6968 or worry about struct utimbuf; gnulib does that for us now.
6969 (gettimeofday): Remove; gnulib provides a substitute.
6970 (make_timeval): New function.
6971 (set_file_times): Now sets ns-resolution time stamps.
6972 New arg FD; all uses changed.
6973 (time_from_jiffies, ltime_from_jiffies, get_up_time)
6974 (system_process_attributes):
6975 Now returns ns-resolution time stamp. All uses changed.
6976 Check for time stamp overflow.
6978 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
6979 provides a substitute now.
6981 * systime.h: Include timespec.h rather than sys/time.h and time.h,
6982 since it guarantees struct timespec.
6983 (EMACS_TIME): Now struct timespec, so that we can support
6984 ns-resolution time stamps.
6985 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
6986 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
6987 (EMACS_USECS): Remove.
6988 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
6989 so multiply the arg by 1000 before storing it.
6990 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
6992 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
6993 Port to ns-resolution time stamps.
6994 (EMACS_TIME_NEG_P): Remove; replaced by....
6995 (EMACS_TIME_SIGN): New macro.

6997 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
6998 (set_file_times, make_time, lisp_time_argument): Adjust signature.
6999 (make_timeval, make_lisp_time, decode_time_components): New decls.
7000 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
7001 that it mishandled time_t overflow. You can't compare by subtracting!
7002 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
7003 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
7005 * term.c: Include <sys/time.h>.

7013 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
7014 (w32_get_internal_run_time):
7015 Port to higher-resolution Emacs time stamps.
7016 (ltime): Now accepts single 64-bit integer, as that's more convenient
7019 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
7021 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
7022 for compatibility with pselect. Support ns-resolution time stamps.
7024 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
7026 * xselect.c (wait_for_property_change, x_get_foreign_selection):
7027 Check for time stamp overflow, and support ns-resolution time stamps.
7029 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
7030 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
7031 (timeval_subtract): Remove; no longer needed.
7032 (XTflash, XTring_bell, x_wait_for_event):
7033 Port to ns-resolution time stamps. Don't assume time_t is signed.
7035 2012-06-22 Chong Yidong <cyd@gnu.org>

7039 2012-06-22 Eli Zaretskii <eliz@gnu.org>
7041 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
7042 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
7043 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
7044 staticidx goes up to 1597 out of 1600 = 0x640.)
7046 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
7048 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
7049 Otherwise, the umask might be mistakenly 0 while handling input signals.

7071 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
7073 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
7074 since tty frames can be explicitly named.
7075 (prepare_menu_bars): Likewise.
7077 * term.c (Ftty_top_frame): New function.

7084 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
7085 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.

7094 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
7095 gets killed during executing of this function (Bug#11665).
7096 Try to always return Qt when the buffer has been actually killed.
7097 (Vkill_buffer_query_functions): In doc-string say that functions
7098 run by this hook should not change the current buffer.
7100 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
7102 Fix recently-introduced process.c problems found by static checking.

7120 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
7122 * lisp.h (eassert): Assume C89 or later.
7123 This removes the need for CHECK.
7124 (CHECK): Remove. Its comments about always evaluating its
7125 argument were confusing, as 'eassert' typically does not evaluate
7128 * coding.c (produce_chars): Use ptrdiff_t, not int.
7130 * xterm.c (x_draw_underwave): Check for integer overflow.
7131 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

7283 * frame.c (delete_frame): Remove outdated comment.
7284 * w32fns.c (Fw32_register_hot_key): Use XLI instead of checking
7285 USE_LISP_UNION_TYPE.

7304 USE_LISP_UNION_TYPE + USE_LSB_TAG cleanup (Bug#11604)
7305 * alloc.c (make_number) [!defined make_number]:

7309 * data.c (Fmake_variable_buffer_local, Fmake_local_variable):
7310 * ftfont.c (ftfont_driver): Use LISP_INITIALLY_ZERO.
7311 * lisp.h (USE_LSB_TAG): Allow the builder to compile with
7312 -DUSE_LSB_TAG=0, to override the automatically-selected default.
7313 USE_LSB_TAG now is always defined to be either 0 or 1.
7315 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
7316 code works fine either way, and efficiency is not a concern here,
7317 as the union type is for debugging, not for production.
7318 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
7319 Use an inline function on all platforms when using the union type,
7320 since this is simpler and 'static inline' can be used portably
7322 (LISP_INITIALLY_ZERO): New macro.
7323 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
7324 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.

7393 dbus_type_is_basic if available.
7394 (xd_extract_signed, xd_extract_unsigned): Rename from
7395 extract_signed and extract_unsigned, respectively. Adapt callers.
7397 2012-06-09 Chong Yidong <cyd@gnu.org>

7406 * xdisp.c (vmessage): Treat frame message as multibyte.
7407 Without this change, (let ((§ 1)) (make-variable-buffer-local '§))
7408 would generate the diagnostic "Making \302\247 buffer-local while
7411 2012-06-08 Eli Zaretskii <eliz@gnu.org>
7413 * dispnew.c (showing_window_margins_p): Undo last change, which

7427 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
7429 2012-06-08 Eli Zaretskii <eliz@gnu.org>
7431 * alloc.c (allocate_vectorlike): Fix last change.
7433 2012-06-08 Dmitry Antipov <dmantipov@yandex.ru>
7435 Block-based vector allocation of small vectors.

7462 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
7464 * doprnt.c (doprnt): Truncate multibyte char correctly.
7465 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
7466 would mishandle a string argument "Xc" if X was a multibyte
7467 character of length 2: it would truncate after X's first byte
7468 rather than including all of X.
7470 2012-06-06 Chong Yidong <cyd@gnu.org>
7472 * buffer.c (word_wrap): Doc fix.

7521 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
7522 Convert pctcpu and pctmem to Lisp float properly.
7523 Let the compiler fold better, as 100.0/0x8000 is exact.
7525 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
7527 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
7530 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
7532 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
7534 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
7536 For a 'struct window', replace some Lisp_Object fields to
7537 bitfields where appropriate, remove unused fields.
7538 * window.h (struct window): Remove unused 'last_mark_x' and
7539 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
7540 change it's type from Lisp_Object to bitfield.
7541 Change type of 'force_start', 'optional_new_start',
7542 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
7543 fields from Lisp_Object to bitfield. Adjust users accordingly.
7545 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
7547 Pacify gcc -Wdouble-precision when using Xaw.
7548 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
7549 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
7550 Use 'float' consistently, rather than 'float' in most places
7551 and 'double' in a couple of places.
7553 2012-05-31 Eli Zaretskii <eliz@gnu.org>
7555 * xdisp.c (handle_stop): Detect whether we have overlay strings
7556 loaded by testing it->current.overlay_string_index to be
7557 non-negative, instead of checking whether n_overlay_strings is
7558 positive. (Bug#11587)
7560 2012-05-31 Chong Yidong <cyd@gnu.org>
7562 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
7564 * doc.c (Fsubstitute_command_keys): Doc fix.
7566 2012-05-31 Eli Zaretskii <eliz@gnu.org>
7568 * search.c (search_buffer): Remove calls to
7569 r_alloc_inhibit_buffer_relocation, as it is now called by
7570 maybe_unify_char, which was the cause of relocation of buffer text
7573 2012-05-31 Eli Zaretskii <eliz@gnu.org>
7575 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
7576 for the duration of call to load_charset, to avoid problems with
7577 callers of maybe_unify_char that access buffer text through C
7580 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
7581 decrement the inhibition flag, instead of just setting or
7584 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
7586 Remove obsolete '#define static' cruft.
7587 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
7588 This #undef was "temporary" in 2000; it is no longer needed
7589 now that '#define static' has gone away.
7590 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
7591 (gray_bitmap_bits): Remove; no longer needed.
7592 All uses replaced with definiens.
7593 * xterm.c: Include "bitmaps/gray.xbm".
7595 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
7597 Clean up __executable_start, monstartup when --enable-profiling.
7598 The following changes affect the code only when profiling.
7599 * dispnew.c (__executable_start): Rename from safe_bcopy.
7600 Define only on platforms that need it.
7601 * emacs.c: Include <sys/gmon.h> when profiling.
7602 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
7603 (__executable_start): Remove decl, since lisp.h does it now.
7604 (safe_bcopy): Remove decl; no longer has that name.
7605 (main): Coalesce #if into single bit of code, for simplicity.

7635 Do not create empty overlays with the evaporate property (Bug#9642).
7636 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
7637 Bug#9642, but explicitly check that the buffer the overlay would
7638 be moved to is live and rearrange lines to make sure that errors
7639 will not put the overlay in an inconsistent state.
7640 (Fdelete_overlay): Cosmetics.
7642 2012-05-28 Eli Zaretskii <eliz@gnu.org>
7644 * w32term.c (my_bring_window_to_top): New function.
7645 (x_raise_frame): Use handle returned by DeferWindowPos, which

7656 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
7658 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
7659 This avoids undefined behavior that might cause the eassert
7660 to not catch an out-of-range value.
7662 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
7664 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

7676 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
7678 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
7679 Only r_alloc_inhibit_buffer_relocation needed to be added;
7680 the others were already declared.
7682 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
7683 before checking whether it's out of range. Put the check inside
7685 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
7687 2012-05-27 Ken Brown <kbrown@cornell.edu>
7689 * callproc.c (Fcall_process): Restore a line that was accidentally
7690 commented out in the 2011-02-13 change (bug#11547).

7694 * lisp.h [REL_ALLOC]: Add prototypes for external functions
7695 defined on ralloc.c.
7697 * buffer.c [REL_ALLOC]: Remove prototypes of
7698 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
7699 they are now on lisp.h.
7701 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
7703 * search.c (search_buffer): Use it to inhibit relocation of buffer
7704 text while re_search_2 is doing its job, because re_search_2 is
7705 passed C pointers to buffer text. (Bug#11519)
7707 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
7710 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
7711 state after an additional call to move_it_in_display_line_to, keep
7712 the values of it->max_ascent and it->max_descent found for the
7714 (pos_visible_p): Revert the comparison against bottom_y to what it
7715 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
7718 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
7720 Fix coding-related core dumps with gcc -ftrapv.
7721 The code was computing A - B, where A and B are pointers, and B is
7722 random garbage. This can lead to core dumps on platforms that
7723 have special pointer registers, and it also leads to core dumps on
7724 x86-64 when compiled with gcc -ftrapv. The fix is to compute
7725 A - B only when B is initialized properly.
7726 * coding.c (coding_set_source, coding_set_destination): Return void.
7727 (coding_change_source, coding_change_destinations): New functions,
7728 with the old behaviors of coding_set_source and coding_set_destination.

7749 gen_help_event to produce help-echo message in the echo area.
7750 Call clear_mouse_face if mouse_face_hidden is set in the mouse
7753 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>

7756 with GCC 4.7.0 on x86-64.
7758 2012-05-26 Eli Zaretskii <eliz@gnu.org>
7760 * bidi.c (bidi_mirror_char): Revert last change: an int is
7761 definitely wide enough here.
7763 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
7765 Fix integer width and related bugs (Bug#9874).

7777 Use int, not EMACS_INT, where int is wide enough.

7797 (Foverlay_recenter, last_overlay_modification_hooks_used)
7798 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
7799 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
7800 (validate_region): Omit unnecessary test for b <= e,
7801 since that's guaranteed by the previous test.
7802 (adjust_overlays_for_delete): Avoid pos + length overflow.
7803 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
7804 (report_overlay_modification):
7805 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
7806 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):

7815 not int, to avoid needless 32-bit limit on 64-bit hosts.
7816 (exec_byte_code): Use tighter memory-full test, one that checks
7817 for alloca overflow. Don't compute the address of the object just
7818 before an array, as that's not portable. Use EMACS_INT, not
7819 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
7820 * callint.c (Fcall_interactively):
7821 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

7833 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
7834 (casify_object): Avoid integer overflow when overallocating buffer.
7835 * casetab.c (set_identity, shuffle): Prefer int to unsigned when

7838 * category.h (CATEGORYP): Don't assume arg is nonnegative.
7839 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the

7842 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
7843 For CCL_MapSingle, check that content and value are in int range.

7845 Check that Vcode_version_map_vector is a vector.
7846 (resolve_symbol_ccl_program): Check that vector header is in range.
7847 Always copy the vector, so that we can check its contents reliably
7848 now rather than having to recheck each instruction as it's being
7849 executed. Check that vector words fit in 'int'.
7850 (ccl_get_compiled_code, Fregister_ccl_program)
7851 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
7852 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
7853 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
7854 contents are in range.
7855 (Fccl_execute_on_string): Check that status is in range.
7856 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
7857 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
7858 Accept and return EMACS_INT, not int, because callers can pass values

7864 (string_escape_byte8, Fget_byte):
7865 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

7867 avoid mishandling large integers.
7868 * character.h: Adjust decls to match defn changes elsewhere.

7878 Don't rely on undefined behavior with signed left shift overflow.
7879 Don't assume unsigned int fits into fixnum, or that fixnum fits
7880 into unsigned int. Don't require max_code to be a valid fixnum;
7881 that's not true for gb10830 4-byte on a 32-bit host. Allow
7882 invalid_code to be a cons, for the same reason. Require code_offset
7883 to be a character. Avoid int overflow if max_char is close
7885 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
7886 this is intended anyway and avoids some undefined behavior.
7887 (load_charset_map): Pass unsigned, not int, as 2nd arg of
7888 INDEX_TO_CODE_POINT, as that's what it expects.
7889 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
7890 * charset.h (DECODE_CHAR): Return int, not unsigned;
7891 this is what was intended anyway, and it avoids undefined behavior.
7892 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
7893 integer-overflow issues.
7894 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
7895 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
7896 where the argument is EMACS_INT, and this behavior is not intended.
7897 * chartab.c (Fmake_char_table, Fset_char_table_range)
7898 (uniprop_get_decoder, uniprop_get_encoder):
7899 Don't assume fixnum fits in int.
7900 * cmds.c (move_point): New function, that does the gist of
7901 Fforward_char and Fbackward_char, but does so while checking
7902 for integer overflow more accurately.
7903 (Fforward_char, Fbackward_char): Use it.
7904 (Fforward_line, Fend_of_line, internal_self_insert)
7905 (internal_self_insert):
7906 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

8689 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
8690 Put "libexec" before "bin", for the sake of init_callproc_1.
8692 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
8694 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.

8697 (report_error, report_error_1, make_hdr, copy_sym)
8698 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
8699 Make arguments const char *, not char *, to avoid violations of C
8700 standard and to fix some AIX warnings reported by Gilles Pion.
8702 2012-05-14 Eli Zaretskii <eliz@gnu.org>
8704 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
8705 already have overlays loaded.
8706 (handle_single_display_spec): Before returning without displaying
8707 fringe bitmap, synchronize the bidi iterator with the main display
8708 iterator, by calling iterate_out_of_display_property.
8709 (iterate_out_of_display_property): Detect buffer iteration by
8710 testing that it->string is a Lisp string.
8711 (get_next_display_element): When the current object is exhausted,
8712 and there's something on it->stack, call set_iterator_to_next to
8713 proceed with what's on the stack, instead of returning zero.
8714 (set_iterator_to_next): If called at the end of a Lisp string,
8715 proceed to consider_string_end without incrementing string
8716 position. Don't increment display vector index past the end of
8717 the display vector. (Bug#11417)
8718 (pos_visible_p): Don't report a position visible when move_it_to
8719 stopped at the last line of window, which happens to be scanned
8720 backwards by the bidi iteration. (Bug#11464)
8722 2012-05-14 Eli Zaretskii <eliz@gnu.org>
8724 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
8725 and right-margin display specs even if the spec is invalid or we
8726 are on a TTY, and thus unable to display on the fringes.
8727 That's because the text with the property will not be displayed anyway,
8728 so we need to signal to the caller that this is a "replacing"
8729 display spec. This fixes display when the spec is invalid or we
8732 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
8734 * unexaix.c (make_hdr): Fix typo in prototype.
8735 This bug broke the build on AIX. Problem reported by Gilles Pion.
8737 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
8739 * keyboard.c (kbd_buffer_get_event): Read special events also in
8740 batch mode. (Bug#11415)

8750 2012-05-12 Glenn Morris <rgm@gnu.org>

8753 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
8755 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>

8765 Update dependencies.
8767 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
8769 * xgselect.c (xg_select): Put maxfds+1 into a var.
8770 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
8772 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
8774 2012-05-10 Dave Abrahams <dave@boostpro.com>
8776 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
8777 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
8779 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
8781 * dbusbind.c (xd_registered_buses): New internal Lisp object.
8782 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
8783 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
8784 Initialize xd_registered_buses.
8786 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
8788 Untag more efficiently if USE_LSB_TAG.
8789 This is based on a proposal by YAMAMOTO Mitsuharu in
8790 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
8791 For an admittedly artificial (nth 8000 longlist) benchmark on
8792 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
8793 Emacs's overall text size by 1%.
8794 * lisp.h (XUNTAG): New macro.
8795 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
8796 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
8797 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
8798 * eval.c (Fautoload):
8799 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
8800 * frame.h (XFRAME): Use XUNTAG.
8802 Port recent dbusbind.c changes to 32-bit --with-wide-int.
8803 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
8804 Remove unportable assumptions about print widths of types like
8806 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
8807 intptr_t when converting between pointer and integer, to avoid GCC
8808 warnings about wrong width.
8810 2012-05-09 Eli Zaretskii <eliz@gnu.org>
8812 * w32proc.c (new_child): Force Windows to reserve only 64KB of
8813 stack for each reader_thread, instead of defaulting to 8MB
8814 determined by the linker. This avoids failures in creating
8815 subprocesses on Windows 7, see the discussion in this thread:
8816 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
8818 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
8820 Fix up display of the *Minibuf-0* buffer in the mini window.
8821 * keyboard.c (read_char): Don't clear the echo area if there's no
8823 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
8824 contents of *Minibuf-0*) if there's no message displayed in its stead.
8826 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
8828 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
8831 2012-05-06 Chong Yidong <cyd@gnu.org>
8833 * lisp.mk (lisp): Update.
8835 2012-05-05 Jim Meyering <meyering@redhat.com>
8837 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
8839 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
8841 * data.c (PUT_ERROR): New macro.
8842 (syms_of_data): Use it. Add new error type `user-error'.
8843 * undo.c (user_error): New function.
8844 (Fprimitive_undo): Use it.
8845 * print.c (print_error_message): Adjust print style for `user-error'.
8846 * keyboard.c (user_error): New function.
8847 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
8849 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
8851 Do not limit current-time-string to years 1000..9999.
8852 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
8853 (Fcurrent_time_string): Support any year that is supported by the
8854 underlying localtime representation. Don't use asctime, as it
8855 has undefined behavior for years outside the range -999..9999.
8857 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
8859 Fix race conditions involving setenv, gmtime, localtime, asctime.
8860 Without this fix, interrupts could mess up code that uses these
8861 nonreentrant functions, since setting TZ invalidates existing
8862 tm_zone or tzname values, and since most of these functions return
8863 pointers to static storage.
8864 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
8865 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
8866 Grow the critical sections to include not just invoking
8867 localtime/gmtime, but also accessing these functions' results
8868 including their tm_zone values if any, and any related TZ setting.
8869 (format_time_string): Last arg is now struct tm *, not struct tm **,
8870 so that the struct tm is saved in the critical section.
8871 All callers changed. Simplify allocation of initial buffer, partly
8872 motivated by the fact that memory allocation needs to be outside
8873 the critical section.
8875 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
8877 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
8878 with RESET_INTERVAL.
8880 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
8881 Remove duplicated buffer name initialization.
8883 2012-05-02 Jim Meyering <jim@meyering.net>
8885 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
8887 * xfns.c (x_window): Use xstrdup (Bug#11375).
8889 2012-05-02 Eli Zaretskii <eliz@gnu.org>
8891 * xdisp.c (pos_visible_p): If already at a newline from the
8892 display string before the 'while' loop, don't walk back the glyphs
8893 from it3.glyph_row. Solves assertion violation when the display
8894 string begins with a newline (egg.el). (Bug#11367)
8896 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
8898 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
8901 2012-05-01 Glenn Morris <rgm@gnu.org>
8903 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
8904 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
8905 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
8906 All were removed before 23.1.
8908 * dispnew.c: Remove HAVE_LIBNCURSES test;
8909 it is always true on relevant platforms.
8911 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
8912 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
8914 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
8916 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
8918 * .gdbinit (xpr): Remove checks for no longer existing misc types.
8919 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
8922 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
8924 Do not avoid creating empty evaporating overlays (Bug#9642).
8925 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
8926 That is, do not delete an evaporating overlay if it becomes
8927 empty after its bounds are adjusted to fit within its buffer.
8928 This fix caused other problems, and I'm reverting it until we get
8929 to the bottom of them.
8931 2012-04-27 Chong Yidong <cyd@gnu.org>
8933 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
8935 2012-04-27 Eli Zaretskii <eliz@gnu.org>
8937 * xdisp.c (pos_visible_p): If the window start position is beyond
8938 ZV, start the display from buffer beginning. Prevents assertion
8939 violation in init_iterator when the minibuffer window is scrolled
8942 * window.c (window_scroll_pixel_based): Likewise.
8944 2012-04-27 Chong Yidong <cyd@gnu.org>
8946 * keymap.c (where_is_internal): Doc fix (Bug#10872).
8948 2012-04-27 Glenn Morris <rgm@gnu.org>
8950 * fileio.c (Fcopy_file, Fset_file_selinux_context):
8951 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
8953 2012-04-27 Eli Zaretskii <eliz@gnu.org>
8955 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
8956 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
8958 2012-04-26 Eli Zaretskii <eliz@gnu.org>
8960 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
8961 display element, check also the underlying string or buffer
8962 character. (Bug#11341)
8964 * w32menu.c: Include w32heap.h.
8965 (add_menu_item): If the call to AppendMenuW (via
8966 unicode_append_menu) fails, disable Unicode menus only if we are
8967 running on Windows 9X/Me.
8969 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
8971 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
8972 (xgetint): Add missing shift for LSB tags.
8974 2012-04-24 Martin Rudalics <rudalics@gmx.at>
8976 * keyboard.c (read_char): Don't wipe echo area for select window
8977 events: These might get delayed via `mouse-autoselect-window'
8980 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
8982 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
8983 manipulation of :loaded-from data.
8985 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
8987 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
8988 now a cons (bug#11311).
8990 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
8992 Do not create empty overlays with the evaporate property (Bug#9642).
8993 * buffer.c (Fmove_overlay): Delete an evaporating overlay
8994 if it becomes empty after its bounds are adjusted to fit within
8995 its buffer. Without this fix, in a nonempty buffer (let ((o
8996 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
8997 yields an empty overlay that has the evaporate property, which is
8998 not supposed to happen.
9000 Fix minor GTK3 problems found by static checking.
9001 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)

9021 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
9022 (__malloc_size_t, __malloc_ptrdiff_t):
9023 Remove. All uses removed, replaced by the definiens if needed,

9105 (mem_init, mem_insert, mem_insert_fixup):
9106 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

9115 * sysdep.c [__FreeBSD__]: Minor cleanups.
9116 (list_system_processes, system_process_attributes) [__FreeBSD__]:
9117 Use Emacs indenting style more consistently. Avoid some casts.
9118 Use 'double' consistently rather than mixing 'float' and 'double'.
9120 2012-04-21 Eduard Wiebe <usenet@pusto.de>
9122 * sysdep.c (list_system_processes, system_process_attributes):

9138 (print_object): Check for cycles even when print-circle is nil and
9139 print-gensym is t, but only check print_depth if print-circle is nil.
9141 2012-04-20 Chong Yidong <cyd@gnu.org>
9143 * process.c (wait_reading_process_output): If EIO occurs on a pty,
9144 set the status to "failed" and ensure that sentinel is run.

9199 New extern decls, to avoid calling undeclared functions.
9200 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
9201 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
9202 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.

9204 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
9205 Remove one incorrect comment and fix another.

9219 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
9220 Remove decls. This fixes an "It stinks!".
9222 * alloc.c (which_symbols): Fix alignment issue / type clash.
9224 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
9226 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

9243 Remove definition of GC_MARK_STACK, since the default now works.
9244 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
9245 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
9246 no longer the default.
9247 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
9249 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
9251 * lread.c (lisp_file_lexically_bound_p):

9272 2012-04-11 Daniel Colascione <dancol@dancol.org>
9274 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
9275 against is gone. It's better to use vfork now so that when Cygwin
9276 gains a new, working vfork, we use it automatically (bug#10398).
9278 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

9304 not just in the obarray, before snarfing them. (Bug#11036)
9306 * Makefile.in ($(leimdir)/leim-list.el):
9307 Pass EMACS rather than BUILT_EMACS.
9309 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
9311 * process.c (make_process):
9312 * process.h: Add integer `gnutls_handshakes_tried' member to
9315 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.
9316 Add convenience `GNUTLS_LOG2i' macro.
9318 * gnutls.c (gnutls_log_function2i): Convenience log function.
9319 (emacs_gnutls_read): Use new log functions,
9320 `gnutls_handshakes_tried' process member, and
9321 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
9322 attempts per process (connection).
9324 2012-04-09 Chong Yidong <cyd@gnu.org>
9326 * eval.c (Fuser_variable_p, user_variable_p_eh)

9331 * minibuf.c (Fread_variable): Callers changed.
9333 2012-04-09 Eli Zaretskii <eliz@gnu.org>
9335 * xdisp.c (set_cursor_from_row): If the display string appears in
9336 the buffer at position that is closer to point than the position
9337 after the display string, display the cursor on the first glyph of
9338 the display string. Fixes cursor display when a 'display' text
9339 property immediately follows invisible text. (Bug#11094)
9341 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
9343 composite.c: use 'double' consistently
9344 * composite.c (get_composition_id): Use 'double' consistently
9345 instead of converting 'float' to 'double' and vice versa; this is
9346 easier to understand and avoids a GCC warning.
9348 2012-04-09 Glenn Morris <rgm@gnu.org>
9350 * Makefile.in: Generate leim-list with bootstrap-emacs, in
9351 preparation for dumping it with emacs. (Bug#4789)
9352 (leimdir): New variable.
9353 ($(leimdir)/leim-list.el): New rule.

9370 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
9372 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
9373 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
9374 (mark_memory): Mark Lisp_Objects only if pointers might hide in
9375 objects, as mark_maybe_pointer will catch them otherwise.
9376 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
9377 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
9379 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
9381 Fix typo that broke non-Windows builds.
9382 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.

9388 * makefile.w32-in (OBJ2): Add xml.$(O).
9389 (GLOBAL_SOURCES): Add xml.c.
9390 ($(BLD)/xml.$(O)): New dependency list.
9392 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
9393 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
9394 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
9395 [!WINDOWSNT]: New macros.
9396 (init_libxml2_functions, libxml2_loaded_p): New functions.
9397 (parse_region): Call fn_xmlCheckVersion instead of using the macro
9398 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
9399 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
9400 Calls xmlCleanupParser only if libxml2 was loaded (or statically
9402 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
9403 Call init_libxml2_functions before calling libxml2 functions.
9404 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
9406 * emacs.c: Don't include libxml/parser.h.
9407 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
9408 xmlCleanupParser directly.
9410 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
9412 2012-04-07 Eli Zaretskii <eliz@gnu.org>
9414 * indent.c (Fvertical_motion): If there is a display string at
9415 point, use it.vpos to compute how many lines to backtrack after
9416 move_it_to point. (Bug#11133)
9418 2012-04-06 Eli Zaretskii <eliz@gnu.org>
9420 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
9421 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
9422 about subtle differences between FETCH_CHAR* and STRING_CHAR*
9423 macros related to unification of CJK characters. For the details,
9424 see the discussion following the message here:
9425 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
9427 2012-04-04 Chong Yidong <cyd@gnu.org>
9429 * keyboard.c (Vdelayed_warnings_list): Doc fix.
9431 2012-04-01 Eli Zaretskii <eliz@gnu.org>
9433 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
9434 instead of alloca. (Bug#11138)
9436 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
9438 * w32menu.c (is_simple_dialog): Properly check lisp types.
9441 2012-03-31 Eli Zaretskii <eliz@gnu.org>
9443 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
9444 position we get to after a call to move_it_to fails the
9445 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
9446 only if we wind up in a string from display property. (Bug#11063)
9448 * window.c (Fdelete_other_windows_internal): Invalidate the row
9449 and column information about mouse highlight, so that redisplay
9450 restores it after reallocating the glyph matrices. (Bug#7464)
9452 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
9453 string comes from a `display' text property, use the buffer
9454 position of that property as if we actually saw that position in
9456 (move_it_by_lines): Remove the assertion that
9457 "it->current_x == 0 && it->hpos == 0" which can be legitimately
9458 violated when there's a before-string at the beginning of a line.
9461 2012-03-30 Eli Zaretskii <eliz@gnu.org>
9463 * xdisp.c (append_space_for_newline): If the default face was
9464 remapped, use the remapped face for the appended newline.
9465 (extend_face_to_end_of_line): Use the remapped default face for
9466 extending the face to the end of the line.
9467 (display_line): Call extend_face_to_end_of_line when the default
9468 face was remapped. (Bug#11068)
9470 2012-03-29 Eli Zaretskii <eliz@gnu.org>
9472 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
9474 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
9476 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
9478 2012-03-27 Glenn Morris <rgm@gnu.org>
9480 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
9483 2012-03-26 Kenichi Handa <handa@m17n.org>
9485 * dispextern.h (struct glyph): Fix previous change. Change the
9486 bit length of glyphless.ch to 25 (Bug#11082).
9488 2012-03-26 Chong Yidong <cyd@gnu.org>
9490 * keyboard.c (Vselection_inhibit_update_commands): New variable.
9491 (command_loop_1): Use it; inhibit selection update for
9492 handle-select-window too (Bug#8996).
9494 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
9496 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
9498 2012-03-25 Kenichi Handa <handa@m17n.org>
9500 * dispextern.h (struct glyph): Change the bit length of
9501 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
9503 2012-03-24 Eli Zaretskii <eliz@gnu.org>
9505 * s/ms-w32.h (tzname): Include time.h before redirecting to
9506 _tzname. Fixes the MSVC build. (Bug#9960)
9508 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
9510 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
9513 * xterm.c (XTread_socket): Only modify handling_signal if
9514 !SYNC_INPUT. (Bug#11080)
9516 2012-03-23 Eli Zaretskii <eliz@gnu.org>
9518 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
9519 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
9520 when fetching a multibyte character consumes more bytes than
9521 CHAR_BYTES returns, due to unification of CJK characters in
9522 string_char. (Bug#11073)
9524 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
9526 * process.c (wait_reading_process_output): Handle pty disconnect
9527 by refraining from sending oneself a SIGCHLD (bug#10933).
9529 2012-03-22 Chong Yidong <cyd@gnu.org>
9531 * dispextern.h (struct it): New member string_from_prefix_prop_p.
9533 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
9534 Mark string as coming from a prefix property.
9535 (handle_face_prop): Use default face for prefix strings (Bug#4281).
9536 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
9538 2012-03-21 Chong Yidong <cyd@gnu.org>
9540 * xfaces.c (Vface_remapping_alist): Doc fix.
9542 2012-03-20 Eli Zaretskii <eliz@gnu.org>
9544 * w32proc.c (Fw32_set_console_codepage)
9545 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
9548 2012-03-20 Chong Yidong <cyd@gnu.org>
9550 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
9551 to reflect default non-nil value of redisplay-dont-pause.
9553 2012-03-19 Kenichi Handa <handa@m17n.org>
9555 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
9556 it fit in a valid range (Bug#11003).
9558 2012-03-18 Eli Zaretskii <eliz@gnu.org>
9560 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
9561 that is not from display property, accept the row as a "cursor
9562 row" if one of the string's character has a non-nil `cursor'
9563 property. Fixes cursor positioning when there are newlines in
9564 overlay strings, e.g. in icomplete.el. (Bug#11035)
9566 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
9568 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
9570 2012-03-12 Chong Yidong <cyd@gnu.org>
9572 * eval.c (inhibit_lisp_code): Rename from
9573 inhibit_window_configuration_change_hook; move from window.c.
9575 * xfns.c (unwind_create_frame_1, Fx_create_frame):
9576 * window.c (run_window_configuration_change_hook)
9577 (syms_of_window): Callers changed.
9579 2012-03-11 Chong Yidong <cyd@gnu.org>

9588 is visible (Bug#10955).
9590 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
9592 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
9594 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
9596 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
9597 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
9600 2012-03-03 Glenn Morris <rgm@gnu.org>
9602 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
9604 2012-03-02 Eli Zaretskii <eliz@gnu.org>
9606 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
9607 position past the first glyph_row that ends at ZV. (Bug#10902)
9608 (redisplay_window, next_element_from_string): Fix typos in
9610 (redisplay_window): Pass to move_it_vertically the margin in
9611 pixels, not in screen lines.
9613 2012-03-02 Glenn Morris <rgm@gnu.org>
9615 * buffer.c (buffer-list-update-hook): Doc fix.
9617 2012-02-29 Eli Zaretskii <eliz@gnu.org>
9619 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
9620 push_it before setting up the iterator for the first overlay
9621 string, even if we have an empty string loaded.
9622 (next_overlay_string): If there's an empty string on the iterator
9623 stack, pop the stack. (Bug#10903)
9625 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
9627 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
9628 Suggested by Stefan Monnier in
9629 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
9630 * alloc.c (widen_to_Lisp_Object): New static function.
9631 (mark_memory): Also mark Lisp_Objects by fetching pointer words
9632 and widening them to Lisp_Objects. This would work even if
9633 USE_LSB_TAG is defined and wide integers are used, which might
9634 happen in a future version of Emacs.
9636 2012-02-25 Chong Yidong <cyd@gnu.org>
9638 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
9641 * xselect.c (Fx_selection_exists_p): Doc fix.
9642 (x_clipboard_manager_save_all): Print an informative message
9643 before saving to clipboard manager.
9645 2012-02-24 Chong Yidong <cyd@gnu.org>
9647 * keyboard.c (process_special_events): Handle all X selection
9648 requests in kbd_buffer, not just the next one (Bug#8869).
9650 2012-02-23 Chong Yidong <cyd@gnu.org>
9652 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
9653 call when setting menu-bar-lines and tool-bar-lines parameters.
9654 (unwind_create_frame_1): New helper function.
9656 * window.c (inhibit_window_configuration_change_hook): New var.
9657 (run_window_configuration_change_hook): Obey it.
9658 (syms_of_window): Initialize it.
9660 2012-02-22 Chong Yidong <cyd@gnu.org>

9669 * buffer.c (Fget_file_buffer): Protect against invalid file
9670 handler return value.

9675 when computing $valmask.
9677 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
9678 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
9679 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
9680 It's useless in that case, and it can cause problems on hosts
9681 that allocate halves of EMACS_INT values separately.
9682 Reported by Dan Horák. Diagnosed by Andreas Schwab in
9683 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
9684 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
9685 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
9686 it avoids undefined behavior on hosts where shifting right by more
9687 than the word width has undefined behavior.
9689 2012-02-19 Chong Yidong <cyd@gnu.org>
9691 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
9692 (Funhandled_file_name_directory, Ffile_name_as_directory)

9695 return values (Bug#10845).
9697 2012-02-18 Eli Zaretskii <eliz@gnu.org>
9699 * .gdbinit (pitx): Fix incorrect references to fields of the
9702 2012-02-17 Chong Yidong <cyd@gnu.org>

9709 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
9711 2012-02-15 Chong Yidong <cyd@gnu.org>
9713 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
9714 marked as special. Also, starting docstrings with * is obsolete.
9716 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
9718 * gnutls.c (emacs_gnutls_write): Fix last change.

9729 2012-02-12 Chong Yidong <cyd@gnu.org>
9731 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
9732 as that creates a dangerous corner case.
9734 * window.c (Fdelete_window_internal): Invalidate the mouse
9735 highlight (Bug#9904).
9737 2012-02-12 Glenn Morris <rgm@gnu.org>
9739 * xselect.c (Fx_own_selection_internal)
9740 (Fx_get_selection_internal, Fx_disown_selection_internal)
9741 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
9742 * nsselect.m (Fx_own_selection_internal)
9743 (Fx_disown_selection_internal, Fx_selection_exists_p)
9744 (Fx_selection_owner_p, Fx_get_selection_internal):
9745 Sync docs and argument specs with the xselect.c versions.
9747 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
9749 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
9751 2012-02-11 Eli Zaretskii <eliz@gnu.org>
9753 * w32select.c (Fx_selection_exists_p): Sync doc string and
9754 argument list with xselect.c. (Bug#10783)

9767 2012-02-07 Chong Yidong <cyd@gnu.org>
9769 * buffer.c (Fbuffer_local_variables)
9770 (buffer_lisp_local_variables): Handle unbound vars correctly;
9771 don't let Qunbound leak into Lisp.
9773 2012-02-07 Glenn Morris <rgm@gnu.org>
9775 * image.c (Fimagemagick_types): Doc fix.
9777 * image.c (imagemagick-render-type): Change it from a lisp object
9778 to an integer. Move the doc here from the lisp manual.

9783 * doc.c (store_function_docstring): Avoid applying docstring of
9784 alias to base function (Bug#2603).

10292 * fileio.c (Finsert_file_contents): Move after-change-function call
10293 to before the "handled:" label, since all "goto handled" appear in
10294 cases where the *-change-functions have already been properly called
10297 2011-12-01 Andreas Schwab <schwab@linux-m68k.org>
10299 * keyboard.c (interrupt_signal): Don't call kill-emacs when
10300 waiting for input. (Bug#10169)

10304 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
10305 verifies glyph row's hash code--we have just reallocated the
10306 glyphs, so their contents can be complete garbage. (Bug#10164)

10352 (ALIGN_GCTYPEBITS) [_MSC_VER]: Define.
10353 (DECL_ALIGN) [_MSC_VER]: Use it, as MSVC doesn't like bit ops in
10354 this macro definition.
10356 * s/ms-w32.h (tzname): Redirect to _tzname for all values of
10359 2011-11-27 Jan Djärv <jan.h.d@swipnet.se>

10377 Indent for consistency with usual Emacs style.
10379 2011-11-25 Eli Zaretskii <eliz@gnu.org>
10381 * xdisp.c (redisplay_window): If cursor row is not fully visible
10382 after recentering, and scroll-conservatively is set to a large
10383 number, scroll window by a few more lines to make the cursor fully
10384 visible and out of scroll-margin. (Bug#10105)
10385 (start_display): Don't move to the next line if the display should
10386 start at a newline that is part of a display vector or an overlay
10387 string. (Bug#10119)
10389 2011-11-24 Juri Linkov <juri@jurta.org>

10412 2011-11-22 Eli Zaretskii <eliz@gnu.org>
10414 * dispnew.c (adjust_glyph_matrix): Don't verify hash code of mode-
10415 and header-lines, as they don't have one computed for them.
10418 * .gdbinit (prow): Make displayed values more self-explaining.
10419 Add row's hash code.
10421 2011-11-21 Lars Magne Ingebrigtsen <larsi@gnus.org>

10464 2011-11-20 Paul Eggert <eggert@cs.ucla.edu>
10466 Standardize on VIRT_ADDR_VARIES behavior (Bug#10042).
10467 Otherwise, valgrind does not work on some platforms.
10468 Problem reported by Andreas Schwab in
10469 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
10470 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
10471 is set, removing the need for VIRT_ADDRESS_VARIES.
10472 (PURE_P): Use a more-efficient implementation that needs just one
10473 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
10474 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
10475 to 4 (xorl, subq, cmpq, setbe).
10476 * alloc.c (pure): Always extern now, since that's the
10477 VIRT_ADDR_VARIES behavior.
10478 (PURE_POINTER_P): Use a single comparison, not two, for
10479 consistency with the new puresize.h.
10480 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
10481 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:
10482 Remove VIRT_ADDR_VARIES no longer needed.

10487 (erase_phys_cursor, update_window_cursor, show_mouse_face)
10488 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
10489 behave as if the cursor position were at the window margin.
10491 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
10492 and the cursor position is out of bounds, behave as if the cursor
10493 position were at the window margin. (Bug#10075)
10495 2011-11-18 Chong Yidong <cyd@gnu.org>
10497 * window.c (Fwindow_combination_limit): Make first argument
10498 non-optional, since it is meaningless for live windows like the

10512 * dispnew.c (swap_glyph_pointers): Swap the used[] arrays and the
10513 hash values of the two rows.
10514 (copy_row_except_pointers): Preserve the used[] arrays and the
10515 hash values of the two rows. (Bug#10035)
10516 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
10518 * xdisp.c (row_hash): New function, body extracted from
10519 compute_line_metrics.
10520 (compute_line_metrics): Call row_hash, instead of computing the
10523 * dispnew.c (verify_row_hash): Call row_hash for computing the
10524 hash code of a row, instead of duplicating code from xdisp.c.
10526 * dispextern.h (row_hash): Add prototype.
10528 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
10530 * frame.c (delete_frame): Don't delete the terminal when the last
10531 X frame is closed if emacs is built with GTK toolkit.

10552 * window.c (Fwindow_nest): Rename to Fwindow_combination_limit.
10553 (Fset_window_nest): Rename to Fset_window_combination_limit.
10554 (Vwindow_nest): Rename to Vwindow_combination_limit.
10555 (recombine_windows, make_parent_window, make_window)
10556 (Fsplit_window_internal, saved_window)
10557 (Fset_window_configuration, save_window_save): Rename all
10558 occurrences of window_nest to window_combination_limit.
10560 2011-11-15 Juanma Barranquero <lekktu@gmail.com>
10562 * image.c (imagemagick_load_image): Fix typo.
10564 2011-11-14 Eli Zaretskii <eliz@gnu.org>
10566 * xdisp.c (display_line): Move the call to
10567 highlight_trailing_whitespace before the call to
10568 compute_line_metrics, since the latter needs to see the final
10569 faces of all the glyphs to compute ROW's hash value.
10570 Fixes assertion violations in row_equal_p. (Bug#10035)
10572 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
10574 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,
10575 just return (bug#10044).
10577 2011-11-12 Eli Zaretskii <eliz@gnu.org>
10579 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
10580 with user-defined heap size. Bump the default size of the temacs
10581 heap to 27MB, to avoid memory warning when running temacs.
10582 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
10584 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
10585 current_matrix and desired_matrix. (Bug#9990)
10586 (verify_row_hash) [XASSERTS]: New function.
10587 (adjust_glyph_matrix, row_equal_p): Use it in xassert to verify
10588 that the hash value of glyph rows is correct.

10617 2011-11-11 Johan Bockgård <bojohan@gnu.org>
10619 * xdisp.c (fill_composite_glyph_string): Always set s->face, to
10620 avoid a crash (bug#9496).
10622 2011-11-09 Chong Yidong <cyd@gnu.org>
10624 * window.c (Fwindow_inside_edges, Fwindow_inside_pixel_edges)

10631 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
10633 Avoid some portability problems by eschewing 'extern inline' functions.
10634 The trivial performance wins aren't worth the portability hassles; see
10635 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
10637 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
10638 (window_box_width, window_box_left, window_box_left_offset)
10639 (window_box_right, window_box_right_offset): Undo previous change,
10640 by removing the "extern"s.
10641 * intervals.c (adjust_intervals_for_insertion)
10642 (adjust_intervals_for_deletion): Undo previous change,
10643 making these static again.
10644 (offset_intervals, temp_set_point_both, temp_set_point)
10645 (copy_intervals_to_string): No longer inline.
10646 * xdisp.c (window_text_bottom_y, window_box_width)

10685 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
10686 This is also needed for porting to any host where GC_MARK_STACK is
10687 not GC_MAKE_GCPROS_NOOPS.
10688 (which_symbols): Use it.
10690 2011-11-07 Kenichi Handa <handa@m17n.org>
10692 * coding.c (coding_set_destination): Check coding->src_pos only
10693 when coding->src_object is a buffer (bug#9910).

10703 * xmenu.c (cleanup_widget_value_tree): New function.
10704 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
10705 calling free_menubar_widget_value_tree directly (Bug#9830).
10707 2011-11-06 Paul Eggert <eggert@cs.ucla.edu>
10709 Fix some portability problems with 'inline'.
10710 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
10711 (window_box_width, window_box_left, window_box_left_offset)
10712 (window_box_right, window_box_right_offset): Declare extern.
10713 Otherwise, these inline functions do not conform to C99 and
10714 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
10715 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
10716 * intervals.c (adjust_intervals_for_insertion)
10717 (adjust_intervals_for_deletion): Now extern, because otherwise the
10718 extern inline functions 'offset_intervals' couldn't refer to it.
10719 (static_offset_intervals): Remove.
10720 (offset_intervals): Rewrite using the old contents of
10721 static_offset_intervals. The old version didn't conform to C99
10722 because an extern inline function contained a reference to an
10723 identifier with static linkage.

10748 consistency with window-child.

10959 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
10960 instead of calling the "wide" APIs directly.

11018 terminal (Bug#6649).
11020 2011-10-20 Eli Zaretskii <eliz@gnu.org>
11022 * dispextern.h (struct bidi_it): New member next_en_type.
11024 * bidi.c (bidi_line_init): Initialize the next_en_type member.
11025 (bidi_resolve_explicit_1): When next_en_pos is valid for the
11026 current character, check also for next_en_type being WEAK_EN.
11027 (bidi_resolve_weak): Don't enter the expensive loop if the current
11028 position is before next_en_pos. Record the bidi type of the first
11029 non-ET, non-BN character we find, in addition to its position.
11030 (bidi_level_of_next_char): Invalidate next_en_type when
11031 next_en_pos is over-stepped.
11033 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
11035 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
11036 * editfns.c: Rewrite current-time-zone so that it invokes
11037 the equivalent of (format-time-string "%Z") to get the time zone name.
11038 This fixes a bug when the time zone name contains characters that
11039 need converting from the system time locale to Emacs internal format.
11040 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
11041 that patch fixed format-time-string to do the conversion, but
11042 I forgot to fix current-time-zone.
11043 (format_time_string): New function, containing most of
11044 what Fformat_time_string used to contain.
11045 (Fformat_time_string): Rewrite in terms of format_time_string.
11046 This doesn't change this function's behavior.
11047 (current-time-zone): Rewrite to use format_time_string.
11048 This fixes the bug reported by Michael Schierl in
11049 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
11050 Jason Rumney's 2007-06-07 change worked around this bug, but
11052 * systime.h (tzname, timezone): Remove no-longer-used declarations.
11054 2011-10-19 Eli Zaretskii <eliz@gnu.org>
11056 * xdisp.c (start_display): If the character at POS is displayed
11057 via a display vector, reset IT->current.dpvec_index to zero.
11058 (try_window_reusing_current_matrix): If a line ends in a display
11059 vector or the next line starts in a display vector, continue
11060 redrawing the window even though the character position of
11061 start_row was reached.
11064 2011-10-18 Chong Yidong <cyd@gnu.org>
11066 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
11067 with nobreak-char-display too.
11069 2011-10-18 Eli Zaretskii <eliz@gnu.org>
11071 Fix part 3 of bug#9771.
11072 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
11073 (bidi_resolve_neutral): Don't enter the expensive loop looking for
11074 non-neutral characters if the current character is a paragraph
11075 separator (a.k.a. Newline). This avoids running the same
11076 expensive loop twice, once when we consume the preceding newline
11077 and the other time when the line actually needs to be displayed.
11078 Avoid the loop when we see neutrals on the base embedding level
11079 following a character whose directionality is the same as the
11080 paragraph's. This avoids running the expensive loop when a line
11081 ends in a long sequence of neutrals, like control characters.
11082 Add assertion against STRONG_AL type. Slightly rearrange code
11083 that determines the type of a neutral given the first non-neutral
11085 (bidi_level_of_next_char): Set next_en_pos to zero when
11086 invalidating its info.
11088 2011-10-17 Eli Zaretskii <eliz@gnu.org>
11090 * xdisp.c (push_display_prop): Determine whether to record string
11091 or buffer position by IT->string, not by IT->method. Allow
11092 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
11093 (move_it_vertically_backward): Don't look for character position
11094 immediately after the newline when in a continuation line.
11097 2011-10-15 Martin Rudalics <rudalics@gmx.at>
11099 * window.c (coordinates_in_window): Rewrite and delabelize
11100 vertical border check. (Bug#5357) (Bug#9618)
11102 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
11104 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
11105 errors in XSetWindowBorder (bug#9310).
11107 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
11109 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
11110 avoid crash when xmalloc overrun checking is enabled.
11112 2011-10-13 Eli Zaretskii <eliz@gnu.org>
11114 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
11115 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
11116 cursor motion with <left> and <right> arrow keys.
11118 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
11119 some callers set that themselves.
11121 2011-10-12 Eli Zaretskii <eliz@gnu.org>
11123 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
11124 display string and the previous row comes from the same string and
11125 is empty. (Bug#9739) (Bug#9738)
11127 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
11129 * doc.c (get_doc_string): Encode file name (bug#9735).
11131 2011-10-12 Eli Zaretskii <eliz@gnu.org>
11133 * bidi.c (bidi_level_of_next_char):
11134 * xdisp.c (get_visually_first_element): Remove old incorrect
11135 comments regarding the Unicode Line Separator character.
11137 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
11139 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
11141 * alloc.c (Fgc_status): Do not access beyond zombies array
11142 boundary if nzombies > MAX_ZOMBIES.
11143 * alloc.c (dump_zombies): Add missing format specifier.
11145 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
11147 * xdisp.c (set_cursor_from_row): Simplify conditionals,
11148 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
11150 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
11151 Some packages use them to denote characters with modifiers.
11153 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
11155 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
11156 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
11157 matching a pp-number. Rename parameter var to var1.
11159 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
11161 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
11163 2011-10-08 Glenn Morris <rgm@gnu.org>
11165 * callint.c (Fcall_interactively): Give a more explicit error for the
11166 'c' case with a non-character input. (Bug#8479)
11168 2011-10-08 Eli Zaretskii <eliz@gnu.org>
11170 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
11172 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
11173 lines that are hscrolled on the left.
11175 * dispnew.c (buffer_posn_from_coords): Account for a possible
11176 presence of header-line. (Bug#4426)
11178 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
11180 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
11181 Don't advertise functionality which we discourage or doesn't work.
11183 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
11185 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
11186 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
11187 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
11188 this makes Emacs dump core during garbage collection on rare
11189 occasions. sizeof is obviously inferior to offsetof here, so
11190 stick with offsetof.
11191 (GC_POINTER_ALIGNMENT): New macro.
11192 (mark_memory): Omit 3rd (offset) arg; caller changed.
11193 Don't assume EMACS_INT alignment is the same as pointer alignment.
11195 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
11197 * keyboard.c (read_key_sequence_remapped): New var.
11198 (read_key_sequence): Compute remapping in the right buffer.
11199 (command_loop_1): Use read_key_sequence's remapping directly.
11201 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
11203 * dired.c (file_name_completion): Don't expand file name.
11204 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
11205 before checking file name handler.
11207 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
11208 they've been requested explicitly (bug#9591).
11210 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
11212 * keymap.c (Fsingle_key_description): Use make_specified_string
11213 instead of build_string to build string from push_key_description.
11216 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
11218 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
11219 This fixes a Y2038 bug on 64-bit hosts.
11220 * buffer.c (reset_buffer):
11221 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
11222 (Fclear_buffer_auto_save_failure):
11223 Use 0, not -1, to represent an unset failure time, since time_t
11224 might not be signed.
11226 Remove dependency on glibc malloc internals.
11227 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11228 Move back here from lisp.h, but with their new implementations.
11229 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
11230 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
11231 * charset.c (charset_table_init): New static var.
11232 (syms_of_charset): Use it instead of xmalloc. This removes a
11233 dependency on glibc malloc internals. See Eli Zaretskii's comment in
11234 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
11235 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11236 Move back to alloc.c.
11237 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
11238 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
11240 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
11242 * nsterm.m (windowDidResize): Call x_set_window_size only when
11243 ns_in_resize is true. Otherwise set pixelwidth/height and
11244 call change_frame_size (Bug#9628).
11246 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
11248 Port --enable-checking=all to Fedora 14 x86-64.
11249 * charset.c (syms_of_charset): Also account for glibc malloc's
11250 internal overhead when calculating the initial malloc maximum.
11252 Port --enable-checking=all to Fedora 14 x86.
11253 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11255 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
11256 (overrun_check_realloc, overrun_check_free):
11257 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
11258 That way, xmalloc returns a properly-aligned pointer even if
11259 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
11260 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
11261 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
11262 into account when calculating the initial malloc maximum.
11263 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11264 Move here from alloc.c, so that charset.c can use it too.
11265 Properly align; the old code wasn't right for common 32-bit hosts
11266 when configured with --enable-checking=all.
11267 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
11268 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
11270 2011-09-29 Eli Zaretskii <eliz@gnu.org>
11272 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
11275 2011-09-28 Eli Zaretskii <eliz@gnu.org>
11277 * xdisp.c (compute_display_string_end): If there's no display
11278 string at CHARPOS, return -1.
11280 * bidi.c (bidi_fetch_char): When compute_display_string_end
11281 returns a negative value, treat the character as a normal
11282 character not covered by a display string. (Bug#9624)
11284 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
11286 * lread.c (Fread_from_string): Fix typo in docstring.
11288 2011-09-27 Eli Zaretskii <eliz@gnu.org>
11290 * xdisp.c (handle_invisible_prop): If invisible text ends on a
11291 newline, reseat the iterator instead of bidi-iterating there one
11292 character at a time. (Bug#9610)
11293 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
11294 TO_CHARPOS if the bidi iterator is at base embedding level.
11296 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
11298 * lread.c (readevalloop): Use correct code for NBSP.
11299 (read1): Likewise. (Bug#9608)
11301 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
11303 * dbusbind.c (Fdbus_register_signal): When service is not
11304 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
11306 2011-09-25 Glenn Morris <rgm@gnu.org>
11308 * buffer.c (truncate-lines): Doc fix.
11310 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
11312 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
11313 (Fset_window_next_buffers): Doc fix.
11315 2011-09-24 Glenn Morris <rgm@gnu.org>
11317 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
11319 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
11321 Fix minor problems found by static checking.
11322 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
11323 * indent.c (Fvertical_motion): Fix == vs = typo.
11325 2011-09-24 Eli Zaretskii <eliz@gnu.org>
11327 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
11328 Default value is now t. Doc fix.
11330 * indent.c (Fvertical_motion): Compute and apply the overshoot
11331 logic when moving up, not only when moving down. Fix the
11332 confusing name and values of the it_overshoot_expected variable;
11333 logic changes accordingly. (Bug#9254) (Bug#9549)
11335 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
11336 CHARPOS is covered by a display string which includes newlines.
11337 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
11338 is covered by a display string with embedded newlines.
11340 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
11342 * dbusbind.c (Fdbus_register_signal): Add match rule to
11343 Vdbus_registered_objects_table. (Bug#9581)
11344 (Fdbus_register_method, Vdbus_registered_objects_table):
11347 2011-09-24 Jim Meyering <meyering@redhat.com>
11349 do not ignore write error for any output size
11350 The previous change was incomplete.
11351 While it makes emacs --batch detect the vast majority of stdout
11352 write failures, errors were still ignored whenever the output size is
11353 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
11354 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
11355 && echo FAIL: ignored write error
11356 FAIL: ignored write error
11357 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
11358 && echo FAIL: ignored write error
11359 FAIL: ignored write error
11360 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
11362 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
11364 * emacs.c (Fkill_emacs): In noninteractive mode exit
11365 non-successfully if a write error occurred on stdout. (Bug#9574)
11367 2011-09-21 Eli Zaretskii <eliz@gnu.org>
11369 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
11372 * dispextern.h (struct it): Update the comment documenting what
11375 2011-09-20 Eli Zaretskii <eliz@gnu.org>
11377 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
11378 a display string, extend search for cursor position to end of row.
11379 (find_row_edges): If the row ends in a newline from a display
11380 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
11381 Handle the case of a display string with multiple newlines.
11382 (Fcurrent_bidi_paragraph_direction): Fix search for previous
11383 non-empty line. Fixes confusing cursor motion with arrow keys at
11384 the beginning of a line that starts with whitespace.
11386 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
11388 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
11391 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
11393 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
11394 boolean (Bug#9154).
11396 2011-09-18 Eli Zaretskii <eliz@gnu.org>
11398 * xdisp.c (display_line): Record maximum and minimum buffer
11399 positions even if no glyphs were produced (e.g., by a zero-width
11400 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
11401 buffer positions that will be removed from the glyph row because
11403 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
11404 column is beyond frame width: don't subtract 1 "pixel" when
11405 computing width of the stretch.
11406 (reseat_at_next_visible_line_start): Undo the change made on
11407 2011-09-17 that saved paragraph information and restored it after
11408 the call to `reseat'. (Bug#9545)
11410 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11412 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
11413 and turn window cursor on if cleared (Bug#9415).
11415 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
11417 * search.c (boyer_moore): Take unibyte characters from pattern
11418 literally. (Bug#9458)
11420 2011-09-18 Eli Zaretskii <eliz@gnu.org>
11422 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
11424 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
11426 Fix minor problem found by static checking.
11427 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
11428 initialized, to pacify gcc -Wuninitialized.
11430 * fileio.c: Report proper errno when syscall falls.
11431 (Finsert_file_contents): Save and restore errno,
11432 so that report_file_error outputs the correct diagnostic.
11433 (Fwrite_region) [CLASH_DETECTION]: Likewise.
11435 2011-09-18 Eli Zaretskii <eliz@gnu.org>
11437 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
11439 2011-09-17 Eli Zaretskii <eliz@gnu.org>
11441 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
11442 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
11444 2011-09-17 Eli Zaretskii <eliz@gnu.org>
11446 * xdisp.c (reseat_at_next_visible_line_start): Keep information
11447 about the current paragraph and restore it after the call to reseat.
11449 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
11450 (bidi_find_paragraph_start): Search back for paragraph beginning
11451 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
11452 (bidi_move_to_visually_next): Only trigger paragraph-related
11453 computations when the last character is a newline or at EOB, not
11454 just any NEUTRAL_B. (Bug#9470)
11456 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
11457 truncated lines if point is covered by a display string. (Bug#9524)
11459 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
11461 * xselect.c: Relax test for outgoing X longs (Bug#9498).
11462 (cons_to_x_long): New function.
11463 (lisp_data_to_selection_data): Use it. Correct the test for
11464 short-versus-long data; it was negated. Break out of vector
11465 loop, for efficiency, when a long datum is discovered.
11467 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
11469 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
11471 2011-09-16 Eli Zaretskii <eliz@gnu.org>
11473 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
11474 GCC PR/17406) by declaring this function with external scope.
11476 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
11478 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
11479 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
11481 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
11483 * editfns.c (Fformat): Correctly handle text properties on "%%".

11492 (fill_composite_glyph_string): Add comments about special meaning
11493 of TAB characters in a composition.
11495 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
11497 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
11498 This occurs when processing a multibyte format.
11499 Problem reported by Wolfgang Jenker.
11501 2011-09-15 Johan Bockgård <bojohan@gnu.org>
11503 * xdisp.c (try_cursor_movement): Only check for exact match if
11504 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
11506 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
11508 Remove unused external symbols.
11509 * dispextern.h (calc_pixel_width_or_height): Remove decl.
11510 * xdisp.c (calc_pixel_width_or_height): Now static.
11511 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
11512 * indent.c (check_display_width):
11513 * w32term.c: Fix comment to match code.
11514 * xterm.c, xterm.h (x_catching_errors): Remove.
11516 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
11518 * xselect.c: Use signed conversions more consistently (Bug#9498).
11519 (selection_data_to_lisp_data): Assume incoming selection data are
11520 signed integers, not unsigned. This is to be consistent with
11521 outgoing selection data, which was modified to use signed integers
11522 in as part of the fix to Bug#9196 in response to Jan D.'s comment
11523 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
11524 expects long, not unsigned long.
11526 2011-09-14 Eli Zaretskii <eliz@gnu.org>
11528 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
11529 computation of loop end. Reported by Johan Bockgård
11532 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
11534 * frame.c (Fother_visible_frames_p): Function deleted.
11536 2011-09-12 Eli Zaretskii <eliz@gnu.org>
11538 * indent.c (compute_motion): Process display vector front to back
11539 rather than the other way around. (Bug#2496)
11541 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
11543 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
11545 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
11547 * minibuf.c (Fread_from_minibuffer): Doc fix.
11549 2011-09-11 Eli Zaretskii <eliz@gnu.org>
11551 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
11552 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
11554 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
11556 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
11557 value for non-existent files.
11559 2011-09-11 Eli Zaretskii <eliz@gnu.org>
11561 * fileio.c (Finsert_file_contents): If the file cannot be opened,
11562 set its "size" to -1. This will set the modtime_size field of
11563 the corresponding buffer to -1, which is what
11564 verify-visited-file-modtime expects for files that do not exist.
11567 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
11569 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
11571 * lisp.h: ... from here. push_key_description is no longer
11572 defined in keyboard.c, so its declaration should not be in
11573 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
11574 logically belongs with push_key_description.
11576 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
11578 * buffer.h: Include <sys/types.h> instead of <time.h>.
11579 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
11580 Problem reported by Herbert J. Skuhra.
11582 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
11584 * xml.c (parse_region): Make the parsing work for
11585 non-comment-starting XML files again (bug#9144).
11587 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
11589 * image.c (gif_load): Fix calculation of bottom and right corner.
11592 2011-09-10 Eli Zaretskii <eliz@gnu.org>
11594 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
11595 redisplay in small windows.
11597 2011-09-09 Eli Zaretskii <eliz@gnu.org>
11599 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
11601 2011-09-08 Martin Rudalics <rudalics@gmx.at>
11603 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
11604 Operate on live windows only.
11606 2011-09-08 Juanma Barranquero <lekktu@gmail.com>

11610 2011-09-07 Eli Zaretskii <eliz@gnu.org>
11612 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
11613 only under bidi iteration.
11615 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
11617 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
11619 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
11621 isnan: Fix porting problem to Solaris 10 with bundled gcc.
11622 Without this fix, the command to link temacs failed due to an
11623 undefined symbol __builtin_isnan. This is because
11624 /usr/include/iso/math_c99.h #defines isnan(x) to
11625 __builtin_isnan(x), but the bundled gcc, which identifies itself
11626 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
11628 * floatfns.c (isnan): #undef, and then #define to a clone of
11630 (Fisnan): Always define, since it's always available now.
11631 (syms_of_floatfns): Always define isnan at the Lisp level.
11633 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
11635 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
11637 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
11639 * fileio.c: Fix bugs with large file offsets (Bug#9428).
11640 The previous code assumed that file offsets (off_t values) fit in
11641 EMACS_INT variables, which is not true on typical 32-bit hosts.
11642 The code messed up by falsely reporting buffer overflow in cases
11643 such as (insert-file-contents "big" nil 1 2) into an empty buffer
11644 when "big" contains more than 2**29 bytes, even though this
11645 inserts just one byte and does not overflow the buffer.
11646 (Finsert_file_contents): Store file offsets as off_t
11647 values, not as EMACS_INT values. Check for overflow when
11648 converting between EMACS_INT and off_t. When checking for
11649 buffer overflow or for overlap, take the offsets into account.
11650 Don't use EMACS_INT for small values where int suffices.
11651 When checking for overlap, fix a typo: ZV was used where
11652 ZV_BYTE was intended.
11653 (Fwrite_region): Don't assume off_t fits into 'long'.
11654 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
11656 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
11658 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
11660 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
11662 sprintf-related integer and memory overflow issues (Bug#9412).
11664 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
11665 (esprintf, exprintf, evxprintf): New functions.
11666 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
11667 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
11668 (modify_event_symbol): Do not assume that the length of
11669 name_alist_or_stem is safe to alloca and fits in int.
11670 (Fexecute_extended_command): Likewise for function name and binding.
11671 (Frecursion_depth): Wrap around reliably on integer overflow.
11672 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
11673 since some callers pass EMACS_INT values.
11674 (Fsingle_key_description): Don't crash if symbol name contains more
11675 than MAX_ALLOCA bytes.
11676 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
11677 (get_minibuffer): Arg is now EMACS_INT, not int.
11678 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
11679 (esprintf, exprintf, evxprintf): New decls.
11680 * window.h (command_loop_level, minibuf_level): Reflect API changes.
11682 * dbusbind.c (signature_cat): New function.
11683 (xd_signature, Fdbus_register_signal):
11684 Do not overrun buffer; instead, report string overflow.
11686 * dispnew.c (add_window_display_history): Don't overrun buffer.
11687 Truncate instead; this is OK since it's just a log.
11689 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
11690 even if the time zone offset is outlandishly large.
11691 Don't mishandle offset == INT_MIN.
11693 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
11694 when creating daemon; the previous buffer-overflow check was incorrect.
11696 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
11697 which has the guts of the old verror function.
11699 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
11700 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
11702 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
11703 (font_unparse_xlfd): Don't blindly alloca long strings.
11704 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
11705 fits in int, when using sprintf. Use single snprintf to count
11706 length of string rather than counting it via multiple sprintfs;
11707 that's simpler and more reliable.
11708 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
11709 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
11710 sprintf, in case result does not fit in int.
11712 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
11713 (fontset_from_font): Print it.
11715 * frame.c (tty_frame_count): Now printmax_t, not int.
11716 (make_terminal_frame, set_term_frame_name): Print it.
11717 (x_report_frame_params): In X, window IDs are unsigned long,
11718 not signed long, so print them as unsigned.
11719 (validate_x_resource_name): Check for implausibly long names,
11720 and don't assume name length fits in 'int'.
11721 (x_get_resource_string): Don't blindly alloca invocation name;
11722 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
11725 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
11726 (xg_check_special_colors, xg_set_geometry):
11727 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
11729 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
11730 Use esprintf, not sprintf, in case result does not fit in int.
11732 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
11733 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
11734 it as a large positive number.
11735 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
11736 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
11738 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
11739 in case result does not fit in int.
11741 * print.c (float_to_string): Detect width overflow more reliably.
11742 (print_object): Make sprintf buffer a bit bigger, to avoid potential
11743 buffer overrun. Don't assume list length fits in 'int'. Treat
11744 print length of 0 as 0, not as infinity; to be consistent with other
11745 uses of print length in this function. Don't overflow print length
11746 index. Don't assume hash table size fits in 'long', or that
11747 vectorlike size fits in 'unsigned long'.
11749 * process.c (make_process): Use printmax_t, not int, to format
11750 process-name gensyms.
11752 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
11754 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
11755 to avoid potential buffer overrun.
11757 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
11758 if X resource line is longer than 512 bytes.
11760 * xfns.c (x_window): Make sprintf buffer a bit bigger
11761 to avoid potential buffer overrun.
11763 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
11765 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
11767 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
11769 Integer overflow fixes for scrolling, etc.
11770 Without these, Emacs silently mishandles large integers sometimes.
11771 For example, "C-u 4294967297 M-x recenter" was treated as if
11772 it were "C-u 1 M-x recenter" on a typical 64-bit host.
11774 * xdisp.c (try_window_id): Check Emacs fixnum range before
11775 converting to 'int'.
11777 * window.c (window_scroll_line_based, Frecenter):
11778 Check that an Emacs fixnum is in range before assigning it to 'int'.
11779 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
11780 values converted from Emacs fixnums.
11781 (Frecenter): Don't wrap around a line count if it is out of 'int'
11782 range; instead, treat it as an extreme value.
11783 (Fset_window_configuration, compare_window_configurations):
11784 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
11786 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
11787 that can exceed INT_MAX. Check that EMACS_INT value is in range
11788 before assigning it to the (possibly-narrower) index.
11789 (match_limit): Don't assume that a fixnum can fit in 'int'.
11791 * print.c (print_object): Use ptrdiff_t, not int, for index that can
11794 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
11795 (Fvertical_motion): Don't wrap around LINES values that don't fit
11796 in 'int'. Instead, treat them as extreme values. This is good
11797 enough for windows, which can't have more than INT_MAX lines anyway.
11799 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
11801 * Require libxml/parser.h to avoid compilation warning.
11803 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
11805 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
11806 since this reportedly can destroy thread storage.
11808 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
11810 * syntax.c (find_defun_start): Update all cache variables if
11811 exiting early (Bug#9401).
11813 2011-08-30 Eli Zaretskii <eliz@gnu.org>
11815 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
11817 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
11818 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
11819 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
11821 * term.c (tty_append_glyph): New function.
11822 (produce_stretch_glyph): Static function and its prototype deleted.
11824 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
11827 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
11829 * image.c (parse_image_spec): Check for nonnegative, not for positive,
11830 when checking :margin (Bug#9390).
11831 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
11832 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
11833 so that the name doesn't mislead. All uses changed.
11835 2011-08-28 Johan Bockgård <bojohan@gnu.org>
11837 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
11840 2011-08-27 Eli Zaretskii <eliz@gnu.org>
11842 * xdisp.c (move_it_to): Don't bail out early when reaching
11843 position beyond to_charpos, if we are scanning backwards.
11844 (move_it_vertically_backward): When DY == 0, make sure we get to
11845 the first character in the line after the newline.
11847 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
11849 * ccl.c: Improve and simplify overflow checking (Bug#9196).
11850 (ccl_driver): Do not generate an out-of-range pointer.
11851 (Fccl_execute_on_string): Remove unnecessary check for
11852 integer overflow, noted by Stefan Monnier in
11853 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
11854 Remove a FIXME that didn't need fixing.
11855 Simplify the newly-introduced buffer reallocation code.
11857 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
11859 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
11861 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
11863 Integer and memory overflow issues (Bug#9196).
11865 * doc.c (get_doc_string): Rework so that
11866 get_doc_string_buffer_size is the actual buffer size, rather than
11867 being 1 less than the actual buffer size; this makes xpalloc more
11870 * image.c (x_allocate_bitmap_record, cache_image):
11871 * xselect.c (Fx_register_dnd_atom):
11872 Simplify previous changes by using xpalloc.
11874 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
11875 since either will do and ptrdiff_t is convenient with xpalloc.
11877 * charset.c (charset_table_size)
11878 (struct charset_sort_data.priority): Now ptrdiff_t.
11879 (charset_compare): Don't overflow if priorities differ greatly.
11880 (Fsort_charsets): Don't assume list length fits in int.
11881 Check for size-calculation overflow when allocating sort data.
11882 (syms_of_charset): Allocate an initial charset table that is
11883 just under 64 KiB, to avoid problems with glibc malloc and mmap.
11885 * cmds.c (internal_self_insert): Check for size-calculation overflow.
11887 * composite.h (struct composition.glyph_len): Now int, not unsigned.
11888 The actual value is always <= INT_MAX, and leaving it unsigned made
11889 overflow checking harder.
11891 * dispextern.h (struct glyph_matrix.rows_allocated)
11892 (struct face_cache.size): Now ptrdiff_t, for convenience in use
11893 with xpalloc. The values are still always <= INT_MAX.
11895 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
11897 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
11898 (SAFE_NALLOCA): New macro.
11900 * region-cache.c (struct boundary.pos, find_cache_boundary)
11901 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
11902 (set_cache_region, invalidate_region_cache)
11903 (revalidate_region_cache, know_region_cache, region_cache_forward)
11904 (region_cache_backward, pp_cache):
11905 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
11906 so that ptrdiff_t * can be passed to xpalloc.
11907 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
11908 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
11909 (pp_cache): Don't assume cache_len fits in int.
11910 * region-cache.h: Adjust extern decls to match.
11912 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
11913 EMACS_INT, since either will do, for xpalloc.
11915 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
11916 (xnmalloc, xnrealloc, xpalloc): New functions.
11918 * bidi.c (bidi_shelve_header_size): New constant.
11919 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
11920 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
11922 * bidi.c (bidi_cache_shrink):
11923 * buffer.c (overlays_at, overlays_in, record_overlay_string)
11925 Don't update size of array until after memory allocation succeeds,
11926 because xmalloc/xrealloc may not return.
11927 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
11928 now that we have proper integer overflow checking.
11929 (record_overlay_string, overlay_strings): Catch overflows when
11930 calculating size of overlay_str_buf.
11932 * callproc.c (Fcall_process): Check for size overflow when
11933 calculating size of args2.
11934 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
11935 Normally we prefer signed values, but sticking with ptrdiff_t would
11936 require adding more-complicated checks.
11938 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
11939 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
11940 Redo buffer-overflow calculations to avoid integer overflow.
11941 Add a FIXME comment where memory seems to be over-allocated.
11943 * character.c (Fstring): Check for size-calculation overflow.
11945 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
11946 unnecessary integer overflow. Check for size overflow.
11947 (encode_coding_object): Don't update size until xmalloc succeeds.
11949 * composite.c (get_composition_id): Check for overflow in glyph
11950 length calculations.
11952 Integer and memory overflow fixes for display code.
11953 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
11954 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
11955 (scrolling_window): Check for overflow in size calculations.
11956 (line_draw_cost, realloc_glyph_pool, add_row_entry):
11957 Don't assume glyph table len fits in int.

11959 (row_table_size): Now ptrdiff_t, not int.
11960 (scrolling_window): Avoid overflow in size calculations.
11961 Don't update size until allocation succeeds.
11962 * fns.c (concat): Check for overflow in size calculations.
11963 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
11964 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.

11967 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
11968 (get_doc_string): Check for size calculation overflow.
11969 Don't update size until allocation succeeds.
11970 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
11971 EMACS_INT, where ptrdiff_t will do.
11972 (Fsubstitute_command_keys): Check for string overflow.
11974 * editfns.c (set_time_zone_rule): Don't assume environment length
11976 (message_length): Now ptrdiff_t, not int.
11977 (Fmessage_box): Don't update size until allocation succeeds.
11978 Don't assume message length fits in int.
11979 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
11981 * emacs.c (main): Do not reallocate argv, since there is a null at
11982 the end that can be overwritten, and this way there's no need to
11983 worry about size-calculation overflow.
11984 (sort_args): Check for size-calculation overflow.
11986 * eval.c (init_eval_once, grow_specpdl): Don't update size until
11988 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
11990 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
11991 (x_set_scroll_bar_width, x_figure_window_size):
11992 Check for integer overflow.
11993 (x_set_alpha): Do not assume XINT fits in int.
11995 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
11996 This is for the members text_lines, text_cols, total_lines, total_cols,
11997 where the system imposes an 'int' limit.
11999 * fringe.c (Fdefine_fringe_bitmap):
12000 Don't update size until alloc works.
12002 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
12003 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
12005 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
12006 Check for size-calculation overflow.
12007 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
12008 do, as we prefer signed integers.
12009 (id_to_widget.max_size, id_to_widget.used)
12010 (xg_store_widget_in_map, xg_remove_widget_from_map)
12011 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
12012 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
12013 Use and return ptrdiff_t, not int.
12014 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
12015 * gtkutil.h: Change prototypes to match the above.
12017 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
12018 are duplicate now that they've been promoted to lisp.h.
12019 (x_allocate_bitmap_record, x_alloc_image_color)
12020 (make_image_cache, cache_image, xpm_load):
12021 Don't update size until alloc is done.

12031 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
12032 Use ptrdiff_t, not int, to count maps.
12033 (read_char_minibuf_menu_prompt): Check for overflow in size
12034 calculations. Don't update size until allocation succeeds.
12035 Redo calculations to avoid overflow.
12036 * keyboard.h: Change prototypes to match the above.
12038 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
12040 (current_minor_maps): Check for size calculation overflow.
12041 * keymap.h: Change prototypes to match the above.
12043 * lread.c (read1, init_obarray): Don't update size until alloc done.

12064 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
12065 for command line length. Do not attempt to address one before the
12066 beginning of an array, as that's not portable.

12069 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
12071 (encode_terminal_code, calculate_costs): Check for size
12072 calculation overflow.
12073 (encode_terminal_code): Use ptrdiff_t, not int, to record glyph

12094 Use ptrdiff_t, not int, for sizes.
12095 (Finternal_make_lisp_face, cache_face):
12096 Check for size calculation overflow.
12097 (cache_face): Treat size calculation overflows as if they were
12098 memory exhaustion (the usual treatment), rather than aborting.
12100 * xfns.c (x_encode_text, x_set_name_internal)
12101 (Fx_change_window_property): Use ptrdiff_t, not int, to count
12102 sizes, since they can exceed INT_MAX in size. Check for size
12103 calculation overflow.
12105 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
12106 (xg_select): Check for size calculation overflow.
12107 Don't update size until alloc done.
12109 * xrdb.c (get_environ_db): Don't assume path length fits in int,
12110 as sprintf is limited to int lengths.
12112 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
12113 (X_LONG_MIN): New macros.
12114 Use them to make the following changes clearer.
12115 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
12116 This change doesn't affect the value now, but it may help remind
12117 future maintainers not to raise the value too much later.
12118 (SELECTION_QUANTUM): Remove, replacing with ...
12119 (selection_quantum): ... new function, which avoids overflow.
12121 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
12122 assumption that selection length fits in 'int'.
12123 (x_reply_selection_request, x_handle_selection_request)
12124 (x_get_window_property, receive_incremental_selection)
12125 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
12126 (lisp_data_to_selection_data, clean_local_selection_data):
12127 Use ptrdiff_t, not int, to record length of selection.
12128 (x_reply_selection_request, x_get_window_property)
12129 (receive_incremental_selection, x_property_data_to_lisp):
12130 Redo calculations to avoid overflow.
12131 (x_reply_selection_request): When sending hint, ceiling it at
12132 X_LONG_MAX rather than relying on wraparound overflow to send
12134 (x_get_window_property, receive_incremental_selection)
12135 (lisp_data_to_selection_data, x_property_data_to_lisp):
12136 Check for size-calculation overflow.
12137 (x_get_window_property, receive_incremental_selection)

12139 Don't store size until memory allocation succeeds.
12140 (x_get_window_property): Plug memory leak on memory exhaustion.
12141 Don't double-block input; malloc is safe here. Don't assume 2**34
12142 - 4 fits in unsigned long. Add an xassert to check
12143 XGetWindowProperty overflow. Be more careful about overflow
12144 calculations, and distinguish size from memory overflow better.
12145 (receive_incremental_selection): When tracing, don't assume
12146 unsigned int is less than INT_MAX.
12147 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
12148 harmful) conversions of unsigned short to int.
12149 (lisp_data_to_selection_data): Don't assume that integers
12150 in the range -65535 through -1 fit in an X unsigned short.
12151 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
12152 result parameters unless successful. Rely on cons_to_unsigned
12153 to report problems with elements; the old code wasn't right anyway.
12154 (x_check_property_data): Check for int overflow; we cannot use
12155 a wider type due to X limits.
12156 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
12158 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.
12160 * xterm.c (x_color_cells, x_send_scrollbar_event, handle_one_xevent)
12161 (x_term_init): Check for size calculation overflow.
12162 (x_color_cells): Don't store size until memory allocation succeeds.
12163 (handle_one_xevent): Use ptrdiff_t, not int, for byte counts.
12164 Don't assume alloca size is less than MAX_ALLOCA.
12165 (x_term_init): Don't assume length fits in int (sprintf is limited
12168 Use ptrdiff_t for composition IDs.
12169 * character.c (lisp_string_width):
12170 * composite.c (composition_table_size, n_compositions)
12171 (get_composition_id, composition_gstring_from_id):
12172 * dispextern.h (struct glyph_string.cmp_id, struct composition_it.id):

12187 * image.c (xpm_get_color_table_h):
12188 * lisp.h (hash_lookup, hash_put):
12189 * minibuf.c (Ftest_completion):
12190 Use ptrdiff_t for hash table indexes, not int (which is too
12191 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
12192 32-bit --with-wide-int hosts).
12194 * charset.c (Fdefine_charset_internal): Check for integer overflow.
12195 Add a FIXME comment about memory leaks.
12196 (syms_of_charset): Don't assume xmalloc returns.
12198 Don't assume that stated character widths fit in int.

12200 * character.h (CHAR_WIDTH):
12201 * indent.c (MULTIBYTE_BYTES_WIDTH):
12202 Use sanitize_char_width to avoid undefined and/or bad behavior
12203 with outlandish widths.
12204 * character.h (sanitize_tab_width): Rename from sanitize_width,
12205 now that we have two such functions. All uses changed.
12206 (sanitize_char_width): New inline function.
12208 Don't assume that tab-width fits in int.
12209 * character.h (sanitize_width): New inline function.
12210 (SANE_TAB_WIDTH): New macro.
12211 (ASCII_CHAR_WIDTH): Use it.
12212 * indent.c (sane_tab_width): Remove. All uses replaced by
12213 SANE_TAB_WIDTH (current_buffer).
12214 * xdisp.c (init_iterator): Use SANE_TAB_WIDTH.
12216 * fileio.c: Integer overflow issues with file modes.
12217 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
12219 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
12220 Remove unreachable code.
12221 (read_hex, load_charset_map_from_file): Check for integer overflow.
12223 * xterm.c: Don't go over XClientMessageEvent limit.
12224 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
12225 (x_send_scroll_bar_event): Likewise. Check that the size does not
12226 exceed limits imposed by XClientMessageEvent, as well as the usual
12227 ptrdiff_t and size_t limits.
12229 * keyboard.c: Overflow, signedness and related fixes.
12230 (make_lispy_movement): Use same integer type in forward decl
12231 that is used in the definition.
12232 (read_key_sequence, keyremap_step):
12233 Change bufsize argument back to int, undoing my 2011-03-30 change.
12234 We prefer signed types, and int is wide enough here.
12235 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
12236 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
12237 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
12238 length, not size_t. Use ptrdiff_t for index, not int.
12239 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
12240 possibility of integer overflow.
12242 Overflow, signedness and related fixes for images.
12244 * dispextern.h (struct it.stack[0].u.image.image_id)
12245 (struct_it.image_id, struct image.id, struct image_cache.size)

12252 * xdisp.c (calc_pixel_width_or_height):
12253 * xfns.c (image_cache_refcount):
12254 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
12255 on typical 64-bit hosts.

12261 when the callers expect that.
12262 (image_ascent): Redo ascent calculation to avoid int overflow.
12263 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
12264 (lookup_image): Remove unnecessary tests.
12265 (xbm_image_p): Locals are now of int, not EMACS_INT,
12266 since parse_image_check makes sure they fit into int.
12267 (png_load, gif_load, svg_load_image):
12268 Prefer int to unsigned where either will do.
12269 (tiff_handler): New function, combining the cores of the
12270 old tiff_error_handler and tiff_warning_handler.
12271 This function is rewritten to use vsnprintf and thereby avoid
12272 stack buffer overflows. It uses only the features of vsnprintf
12273 that are common to both POSIX and native Microsoft.
12274 (tiff_error_handler, tiff_warning_handler): Use it.
12275 (tiff_load, gif_load, imagemagick_load_image):
12276 Don't assume :index value fits in 'int'.
12277 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
12278 (imagemagick_load_image): Check that crop parameters fit into
12279 the integer types that MagickCropImage accepts. Don't assume
12280 Vimagemagick_render_type has a nonnegative value. Don't assume
12281 size_t fits in 'long'.
12282 (gs_load): Use printmax_t to print the widest integers possible.
12283 Check for integer overflow when computing image height and width.
12285 2011-08-26 Eli Zaretskii <eliz@gnu.org>
12287 * xdisp.c (redisplay_window): Don't force window start if point
12288 will be invisible in the resulting window. (Bug#9324)

12292 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
12293 the display spec is of the form `(space ...)'.
12294 (handle_display_spec): Return the value returned by
12295 handle_single_display_spec, not just 1 or zero.
12296 (handle_single_display_spec): If the display spec is of the form
12297 `(space ...)', and specifies display in the text area, return 2
12299 (try_cursor_movement): Check for the need to scroll more
12300 accurately, and prefer exact match for point under bidi.
12301 Don't advance `row' beyond the last row of the window.
12303 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
12304 into disp_prop; all users changed.
12306 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
12307 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
12308 for the text covered by the display property.

12318 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
12319 buffers, return left-to-right.
12320 (set_cursor_from_row): Consider candidate row a win if its glyph
12321 represents a newline and point is on that newline. Fixes cursor
12322 positioning on the newline at EOL of R2L text within L2R
12323 paragraph, and vice versa.
12324 (try_cursor_movement): Check continued rows, in addition to
12325 continuation rows. Fixes unwarranted scroll when point enters a
12326 continued line of R2L text within an L2R paragraph, or vice versa.
12327 (cursor_row_p): Consider the case of point being equal to
12328 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
12329 from the end of a short line to the beginning of a continued line
12330 of R2L text within L2R paragraph.
12331 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
12332 composed characters.
12334 * bidi.c (bidi_check_type): Use xassert.

12345 * nsfont.m (ns_otf_to_script): Fix typo.
12347 2011-08-22 Kenichi Handa <handa@m17n.org>
12349 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
12350 extra slot even if the purpose is char-code-property-table.
12352 2011-08-23 Eli Zaretskii <eliz@gnu.org>
12354 * xdisp.c (redisplay_window): When computing centering_position,
12355 account for the height of the header line. (Bug#8874)
12357 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
12358 instead of CHAR_TO_BYTE. Fixes a crash when a completion
12359 candidate is selected by the mouse, and that candidate has a
12360 composed character under the mouse.
12362 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
12363 coordinates reported by pos-visible-in-window-p for a composed
12364 character in column zero.
12366 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
12368 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
12370 2011-08-22 Eli Zaretskii <eliz@gnu.org>
12372 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
12373 consider it a hit if to_charpos is anywhere in the range of the
12374 composed buffer positions.
12376 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
12378 * image.c (gif_load): Don't assume that each subimage has the same
12379 dimensions as the base image. Handle disposal method that is
12380 "undefined" by the gif spec (Bug#9335).
12382 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
12384 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

12387 2011-08-19 Eli Zaretskii <eliz@gnu.org>
12389 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
12390 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
12391 from an Org mode buffer to a Speedbar frame.
12393 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
12394 a composition, take its buffer position from IT->cmp_it.charpos.
12395 Fixes cursor positioning at the beginning of a line that begins
12396 with a composed character.
12398 2011-08-18 Eli Zaretskii <eliz@gnu.org>
12400 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
12401 character bidirectional type, use STRONG_L instead. Fixes crashes
12402 in a buffer produced by `describe-categories'.
12404 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
12405 members before the level stack, so they would be saved and
12406 restored when copying iterator state. Fixes incorrect reordering
12407 around TABs covered by display properties.
12409 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
12411 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

12419 2011-08-17 Eli Zaretskii <eliz@gnu.org>
12421 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
12422 has no `load' handler, try opening the file locally. (Bug#9311)
12424 2011-08-16 Ken Brown <kbrown@cornell.edu>

12431 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.
12433 2011-08-16 Ken Brown <kbrown@cornell.edu>
12435 Fix memory allocation problems in Cygwin build (Bug#9273).
12437 * unexcw.c ( __malloc_initialized): Declare external variable.
12438 (fixup_executable): Force the dumped emacs to reinitialize malloc.
12440 * gmalloc.c [CYGWIN] (bss_sbrk_heapbase, bss_sbrk_heapinfo):
12442 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the

12471 coordinates of the iterator when restoring from ppos_it.
12474 2011-08-14 Kenichi Handa <handa@m17n.org>
12476 * process.c (create_process): Call setup_process_coding_systems
12477 after the pid of the process is set to -1 (Bug#8162).
12479 2011-08-14 Eli Zaretskii <eliz@gnu.org>
12481 * xdisp.c (move_it_in_display_line_to): Don't invoke
12482 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
12483 ppos_it. Fixes vertical cursor motion when line beginning is
12484 covered by an image. (Bug#9296)
12486 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
12488 * nsterm.h (ns_run_ascript): Declare.
12489 (NSAPP_DATA2_RUNASSCRIPT): Define.
12491 * nsfns.m (as_script, as_result, as_status): New static variables.
12492 (ns_run_ascript): New function.
12493 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
12494 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
12495 the event loop. Get status from as_status (Bug#7276).
12497 * nsterm.m (sendEvent): If event is NSApplicationDefined and
12498 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
12499 the event loop (Bug#7276).
12501 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
12503 * gnutls.c (QCgnutls_bootprop_priority)

12524 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
12525 (Fnetwork_interface_list): Allocate in increments of bytes instead
12526 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
12527 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
12529 (struct ifflag_def): notrailers is smart on OSX.
12530 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
12531 Get hardware address with getifaddrs if available.
12533 2011-08-12 Eli Zaretskii <eliz@gnu.org>
12535 * xdisp.c (iterate_out_of_display_property): xassert that
12536 IT->position is set to within IT->object's boundaries. Break from
12537 the loop as soon as EOB is reached; avoids infloops in redisplay
12538 when IT->position is set up wrongly due to some bug.
12539 Set IT->current to match the bidi iterator unconditionally.
12540 (push_display_prop): Allow GET_FROM_STRING as IT->method on
12541 entry. Force push_it to save on the stack the current
12542 buffer/string position, to be restored by pop_it. Fix flags in
12543 the iterator structure wrt the object coming from a display
12544 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
12545 properties. (Bug#9284)
12547 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
12549 * fontset.c (fontset_get_font_group): Add proper type checks.
12552 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
12554 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
12555 and LC_VERSION_MIN_MACOSX.

12559 2011-08-08 Eli Zaretskii <eliz@gnu.org>
12561 * xdisp.c (forward_to_next_line_start): Allow to use the
12562 no-display-properties-and-no-overlays under bidi display.
12563 Set disp_pos in the bidi iterator to avoid searches for display
12564 properties and overlays.
12566 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
12568 * editfns.c (Fset_time_zone_rule): Document relationship with the

12572 the font entity extracted from the cache (Bug#8109).
12574 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
12576 * composite.c (autocmp_chars): Don't reset point. That is done by
12577 restore_point_unwind (Bug#5984).
12579 2011-08-07 Juri Linkov <juri@jurta.org>
12581 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
12582 to show the arg `TIME' instead of `TIMEVAL'.
12584 2011-08-06 Eli Zaretskii <eliz@gnu.org>
12586 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
12587 display property strides EOL and includes a newline, as in
12588 longlines-mode. (Bug#9254)
12589 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
12590 word-wrap under bidirectional display. (Bug#9224)
12592 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
12593 is non-zero, even if the data buffer is NULL. Fixes a crash in
12594 vertical-motion with longlines-mode. (Bug#9254)
12596 2011-08-05 Eli Zaretskii <eliz@gnu.org>
12598 * bidi.c <bidi_cache_total_alloc>: Now static.
12599 (bidi_initialize): Initialize bidi_cache_total_alloc.
12601 * xdisp.c (display_line): Release buffer allocated for shelved bidi
12604 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
12605 amount allocated this far in `bidi_cache_total_alloc'.
12606 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
12607 non-zero, only free the data buffer without restoring the cache
12608 contents. All callers changed.
12610 * dispextern.h (bidi_unshelve_cache): Update prototype.
12612 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
12613 (move_it_in_display_line, move_it_to)
12614 (move_it_vertically_backward, move_it_by_lines): Replace the call
12615 to xfree to an equivalent call to bidi_unshelve_cache.
12616 (move_it_in_display_line_to): Fix logic of returning
12617 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
12619 2011-08-05 Eli Zaretskii <eliz@gnu.org>
12621 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
12622 came from a string character with a `cursor' property. (Bug#9229)
12624 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
12626 * Makefile.in (LIB_PTHREAD): New variable.
12627 (LIBES): Add LIB_PTHREAD (Bug#9216).
12629 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
12630 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
12632 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
12634 * regex.c (re_iswctype): Remove some redundant boolean conversions.
12636 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
12638 * xterm.c (x_find_topmost_parent): New function.
12639 (x_set_frame_alpha): Find topmost parent window with
12640 x_find_topmost_parent and set the property there also (bug#9181).
12641 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
12643 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
12645 * callproc.c (Fcall_process): Avoid vfork clobbering
12646 the local vars buffer, coding_systems, current_dir.
12648 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
12650 * keymap.c (Fmake_composed_keymap): Move to subr.el.
12652 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
12654 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
12655 so that it is not optimized away.
12657 * xdisp.c (compute_display_string_pos): Remove unused local.
12659 2011-08-02 Eli Zaretskii <eliz@gnu.org>
12661 Fix slow cursor motion and scrolling in large buffers with
12662 selective display, like Org Mode buffers. (Bug#9218)
12664 * dispextern.h (struct bidi_it): New member disp_prop_p.
12666 * xdisp.c: Remove one-slot cache of display string positions.
12667 (compute_display_string_pos): Accept an additional argument
12668 DISP_PROP_P; callers changed. Scan at most 5K characters forward
12669 for a display string or property. If found, set DISP_PROP_P
12672 * bidi.c (bidi_fetch_char): Accept an additional argument
12673 DISP_PROP_P, and pass it to compute_display_string_pos.
12674 Only handle text covered by a display string if DISP_PROP_P is returned
12675 non-zero. All callers of bidi_fetch_char changed.
12677 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
12679 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
12681 2010-12-03 Don March <don@ohspite.net>
12683 * keymap.c (Fdefine_key): Fix non-prefix key error message when
12684 last character M-[char] is translated to ESC [char] (bug#7541).
12686 2011-08-02 Kenichi Handa <handa@m17n.org>
12688 * lisp.h (uniprop_table): Extern it.
12690 * chartab.c (uniprop_table): Make it non-static.
12692 2011-08-01 Eli Zaretskii <eliz@gnu.org>
12694 * xdisp.c (forward_to_next_line_start): Accept additional argument
12695 BIDI_IT_PREV, and store into it the state of the bidi iterator had
12697 (reseat_at_next_visible_line_start): Use the bidi iterator state
12698 returned by forward_to_next_line_start to restore the state of
12699 it->bidi_it after backing up to previous newline. (Bug#9212)
12701 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
12703 * regex.c (re_comp): Protoize.
12704 (re_exec): Fix return type.
12705 (regexec): Fix type of `ret'. (Bug#9203)
12707 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
12709 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
12710 This is needed if max-image-size is a floating-point number.
12712 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
12714 * print.c (print_object): Print empty symbol as ##.
12716 * lread.c (read1): Read ## as empty symbol.
12718 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
12720 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
12721 setting frame foreground color (Bug#9175).
12722 (x_set_background_color): Likewise.
12724 * nsmenu.m (-setText): Size tooltip dimensions precisely to
12725 contents (Bug#9176).
12726 (EmacsTooltip -init): Remove bezels and add shadows to
12729 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
12730 or scroll bar (Bug#8470).
12732 * nsfont.m (nsfont_open): Remove assignment to voffset and
12733 unnecessary vars hshink, expand, hd, full_height, min_height.
12734 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
12736 * nsterm.h (nsfont_info): Remove voffset field.
12738 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
12740 Implement strike-through and overline on NextStep (Bug#8863).
12742 * nsfont.m (nsfont_open): Use underline position provided by font,
12743 instead of hard-coded value of 2.
12744 (nsfont_draw): Call ns_draw_text_decoration instead.
12746 * nsterm.h: Add declaration for ns_draw_text_decoration.
12748 * nsterm.m (ns_draw_text_decoration): New function for drawing
12749 underline, overline, and strike-through.
12750 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
12751 ns_draw_text_decoration. Change treatment of cursor drawing to
12752 accommodate underlining, etc.
12754 2011-07-28 Eli Zaretskii <eliz@gnu.org>
12756 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
12759 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
12761 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
12762 Without this fix, if a signal arrives just after memory fills up,
12763 'malloc' might be invoked reentrantly.
12765 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
12766 In other words, assume that every image size is allowed, on non-X
12767 hosts. This assumption is probably wrong, but it lets Emacs compile.
12769 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
12771 * regex.c (re_iswctype): Convert return values to boolean.
12773 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
12775 * xdisp.c (compute_display_string_pos): Don't use cached display
12776 string position if the buffer had its restriction changed.
12779 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
12781 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
12783 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
12785 Integer signedness and overflow and related fixes. (Bug#9079)
12787 * bidi.c: Integer size and overflow fixes.
12788 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
12789 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
12790 (bidi_cache_find_level_change, bidi_cache_ensure_space)
12791 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
12792 (bidi_find_other_level_edge):
12793 Use ptrdiff_t instead of EMACS_INT where either will do.
12794 This works better on 32-bit hosts configured --with-wide-int.
12795 (bidi_cache_ensure_space): Check for size-calculation overflow.
12796 Use % rather than repeated addition, for better worst-case speed.
12797 Don't set bidi_cache_size until after xrealloc returns, because it
12799 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
12800 (bidi_cache_ensure_space): Also check that the bidi cache size
12801 does not exceed that of the largest Lisp string or buffer. See Eli
12802 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
12804 * alloc.c (__malloc_size_t): Remove.
12805 All uses replaced by size_t. See Andreas Schwab's note
12806 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
12808 * image.c: Improve checking for integer overflow.
12809 (check_image_size): Assume that f is nonnull, since
12810 it is always nonnull in practice. This is one less thing to
12811 worry about when checking for integer overflow later.
12812 (x_check_image_size): New function, which checks for integer
12813 overflow issues inside X.
12814 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
12815 This removes the need for a memory_full check.
12816 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
12817 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
12818 (xbm_read_bitmap_data): Change locals back to 'int', since
12819 their values must fit in 'int'.
12820 (xpm_load_image, png_load, tiff_load):
12821 Invoke x_create_x_image_and_pixmap earlier,
12822 to avoid much needless work if the image is too large.
12823 (tiff_load): Treat overly large images as if
12824 x_create_x_image_and_pixmap failed, not as malloc failures.
12825 (gs_load): Use x_check_image_size.
12827 * gtkutil.c: Omit integer casts.
12828 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
12829 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
12831 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
12833 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
12834 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
12835 would wrongly return t on a 64-bit host.
12837 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
12838 The plain *_OVERFLOW macros run afoul of GCC bug 49705
12839 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
12840 and therefore cause GCC to emit a bogus diagnostic in some cases.
12842 * image.c: Integer signedness and overflow and related fixes.
12843 This is not an exhaustive set of fixes, but it's time to
12844 record what I've got.
12845 (lookup_pixel_color, check_image_size): Remove redundant decls.
12846 (check_image_size): Don't assume that arbitrary EMACS_INT values
12847 fit in 'int', or that arbitrary 'double' values fit in 'int'.
12848 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
12849 (tiff_load, imagemagick_load_image):
12850 Check for overflow in size calculations.
12851 (x_create_x_image_and_pixmap): Remove unnecessary test for
12852 xmalloc returning NULL; that can't happen.
12853 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
12854 (xpm_color_bucket): Use better integer hashing function.
12855 (xpm_cache_color): Don't possibly over-allocate memory.
12856 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
12857 (gif_memory_source):
12858 Use ptrdiff_t, not int or size_t, to record sizes.
12859 (png_load): Don't assume values greater than 2**31 fit in 'int'.
12860 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
12861 either works, as we prefer signed integers.
12862 (tiff_read_from_memory, tiff_write_from_memory):
12863 Return tsize_t, not size_t, since that's what the TIFF API wants.
12864 (tiff_read_from_memory): Don't fail simply because the read would
12865 go past EOF; instead, return a short read.
12866 (tiff_load): Omit no-longer-needed casts.
12867 (Fimagemagick_types): Don't assume size fits into 'int'.
12869 Improve hashing quality when configured --with-wide-int.
12870 * fns.c (hash_string): New function, taken from sxhash_string.
12871 Do not discard information about ASCII character case; this
12872 discarding is no longer needed.
12873 (sxhash-string): Use it. Change sig to match it. Caller changed.
12874 * lisp.h: Declare it.
12875 * lread.c (hash_string): Remove, since we now use fns.c's version.
12876 The fns.c version returns a wider integer if --with-wide-int is
12877 specified, so this should help the quality of the hashing a bit.
12879 * emacs.c: Integer overflow minor fix.
12880 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
12881 Define only if GNU_LINUX.
12882 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
12884 * dispnew.c: Integer signedness and overflow fixes.
12885 Remove unnecessary forward decls, that were a maintenance hassle.
12886 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
12888 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
12889 (scrolling_window): Use ptrdiff_t, not int, for byte count.
12890 (prepare_desired_row, line_draw_cost):
12891 Use int, not unsigned, where either works.
12892 (save_current_matrix, restore_current_matrix):
12893 Use ptrdiff_t, not size_t, where either works.
12894 (init_display): Check for overflow more accurately, and without
12895 relying on undefined behavior.
12897 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
12898 Remove, replacing with the new symbols in lisp.h. All uses changed.
12899 * fileio.c (make_temp_name):
12900 * filelock.c (lock_file_1, lock_file):
12901 * xdisp.c (message_dolog):
12902 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
12903 Use pMd etc. instead.
12904 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
12905 replacing the pWIDE etc. symbols removed from editfns.c.
12907 * keyboard.h (num_input_events): Now uintmax_t.
12908 This is (very slightly) less likely to mess up due to wraparound.
12911 * buffer.c: Integer signedness fixes.
12912 (alloc_buffer_text, enlarge_buffer_text):
12913 Use ptrdiff_t rather than size_t when either will do, as we prefer
12916 * alloc.c: Integer signedness and overflow fixes.
12917 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
12918 (__malloc_size_t): Default to size_t, not to int.
12919 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
12920 (Fgarbage_collect, mark_object_loop_halt, mark_object):
12921 Prefer ptrdiff_t to size_t when either would do, as we prefer
12923 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
12924 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
12925 Now const. Initialize with values that are in range even if char
12927 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
12928 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
12929 These functions do the right thing with sizes > 2**32.
12930 (check_depth): Now ptrdiff_t, not int.
12931 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
12932 Adjust to new way of storing sizes. Check for size overflow bugs
12934 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
12935 slightly wrong anyway, as it missed one instance of
12936 XMALLOC_OVERRUN_CHECK_OVERHEAD.
12937 (refill_memory_reserve): Omit needless cast to size_t.
12938 (mark_object_loop_halt): Mark as externally visible.
12940 * xselect.c: Integer signedness and overflow fixes.
12941 (Fx_register_dnd_atom, x_handle_dnd_message):
12942 Use ptrdiff_t, not size_t, since we prefer signed.
12943 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
12944 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
12945 x_dnd_atoms_size and x_dnd_atoms_length.
12947 * doprnt.c: Prefer signed to unsigned when either works.
12949 * doprnt.c (doprnt):
12951 * xdisp.c (vmessage):
12952 Use ptrdiff_t, not size_t, when using or implementing doprnt,
12953 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
12954 prefer signed arithmetic to avoid comparison confusion.
12955 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
12956 but is a bit tricky.
12958 Assume freestanding C89 headers, string.h, stdlib.h.
12959 * data.c, doprnt.c, floatfns.c, print.c:
12960 Include float.h unconditionally.
12961 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
12962 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
12963 * regex.c: Likewise for stddef.h, string.h.
12964 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
12965 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
12966 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
12967 (STDC_HEADERS): Remove obsolete defines.
12968 * sysdep.c: Include limits.h unconditionally.
12970 Assume support for memcmp, memcpy, memmove, memset.
12971 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
12972 * regex.c (memcmp, memcpy):
12973 Remove; we assume C89 now.
12975 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
12976 (__malloc_safe_bcopy): Remove; no longer needed.
12978 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
12979 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
12980 well either way, and we prefer signed to unsigned.

12984 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
12985 closes the connection while we're reading (bug#9182).
12987 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
12989 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
12990 are specified (Bug#9168).
12992 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
12994 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
12995 Found by GCC static checking and --with-wide-int on a 32-bit host.
12997 2011-07-25 Eli Zaretskii <eliz@gnu.org>
12999 * xdisp.c (compute_display_string_pos): Fix logic of caching
13000 previous display string position. Initialize cached_prev_pos to
13001 -1. Fixes slow-down at the beginning of a buffer.
13003 2011-07-24 Eli Zaretskii <eliz@gnu.org>
13005 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
13006 for attrs[LFACE_FONTSET_INDEX].
13008 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
13010 * xml.c (parse_region): Remove unused local
13011 that was recently introduced.
13013 2011-07-23 Eli Zaretskii <eliz@gnu.org>
13015 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
13016 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
13018 * xdisp.c (move_it_in_display_line_to): Record the best matching
13019 position for TO_CHARPOS while scanning the line, and restore it on
13020 exit if none of the characters scanned was an exact match.
13021 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
13022 when exact match is impossible due to invisible text, and the
13023 lines are truncated.
13025 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
13027 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
13030 2011-07-22 Eli Zaretskii <eliz@gnu.org>
13032 Fix a significant slow-down of cursor motion with C-n, C-p,
13033 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
13034 auto-repeat under bidi redisplay in fontified buffers.
13035 * xdisp.c (compute_stop_pos_backwards): New function.
13036 (next_element_from_buffer): Call compute_stop_pos_backwards to
13037 find a suitable prev_stop when we find ourselves before
13039 (reseat): Don't look for prev_stop, as that could mean a very long
13041 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
13042 <cached_disp_overlay_modiff>: Cache for last found display string
13044 (compute_display_string_pos): Return the cached position if asked
13045 about the same buffer in the same area of character positions, and
13046 the buffer wasn't changed since the time the display string
13047 position was cached.
13049 2011-07-22 Eli Zaretskii <eliz@gnu.org>
13051 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
13052 is an integer, which is important for empty lines. (Bug#9149)
13054 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
13056 * frame.c (Fmodify_frame_parameters): In tty case, update the
13057 default face if necessary (Bug#4238).
13059 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
13061 * editfns.c (Fstring_to_char): No need to explain what a character
13062 is in the docstring (Bug#6576).
13064 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
13066 * xml.c (parse_region): Make sure we always return a tree.
13068 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
13070 * xml.c (parse_region): If a document contains only comments,
13073 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
13075 * xml.c (make_dom): Return comments, too.
13077 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
13080 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
13081 and the surrounding thread.
13082 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
13083 rather than fgets, and retry after EINTR. Otherwise, 'emacs
13084 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
13086 * s/openbsd.h (BROKEN_SIGIO): Define.
13087 * unexelf.c (unexec) [__OpenBSD__]:
13088 Don't update the .mdebug section of the Alpha COFF symbol table.
13090 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
13092 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
13095 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
13097 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
13098 This fixes some race conditions on the permissions of any newly
13101 * alloc.c (valid_pointer_p): Use pipe, not open.
13102 This fixes some permissions issues when debugging.
13104 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
13105 If fchown fails to set both uid and gid, try to set just gid,
13106 as that is sometimes allowed. Adjust the file's mode to eliminate
13107 setuid or setgid bits that are inappropriate if fchown fails.
13109 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
13111 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ

13117 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
13119 * lread.c (read_integer): Unread even EOF character.
13120 (read1): Likewise. Properly record start position of symbol.

13123 symbol character follows.
13125 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
13127 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
13128 This works around a problem with the previous change to Fcopy_file.
13129 Recent glibc declares fchown with __attribute__((warn_unused_result)),
13130 and without this change, GCC might complain about discarding
13131 fchown's return value.
13133 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
13135 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
13137 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
13139 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
13141 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
13143 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
13144 it's used from the C level.
13146 * process.c: Use the same condition for POLL_FOR_INPUT in both
13147 keyboard.c and process.c (bug#1858).
13149 2011-07-09 Lawrence Mitchell <wence@gmx.li>
13151 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
13152 (Fgnutls_boot): Use it.
13154 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
13156 * doc.c (Fsubstitute_command_keys): Revert last change.
13158 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
13160 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
13161 quotes the next character, and doesn't affect other longer
13162 sequences (bug#8935).
13164 * lread.c (syms_of_lread): Clarify that is isn't only
13165 `eval-buffer' and `eval-defun' that's affected by
13166 `lexical-binding' (bug#8460).
13168 2011-07-15 Eli Zaretskii <eliz@gnu.org>
13170 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
13171 bidi redisplay when a line includes both an image and is truncated.
13173 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
13175 Fix minor problems found by static checking.
13176 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
13177 (elsz): Now a signed constant, not a size_t var. We prefer signed
13178 types to unsigned, to avoid integer comparison confusion. Without
13179 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
13180 "cannot optimize loop, the loop counter may overflow", a symptom
13182 * indent.c (Fvertical_motion): Mark locals as initialized.
13183 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
13185 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
13187 * search.c (Fre_search_backward): Mention `case-fold-search' in
13188 all the re_search_* functions (bug#8138).

13211 (display_string): If we need to ignore text properties of
13212 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
13213 original value of -1 will not work with bidi.)
13214 (compute_display_string_pos): First arg is now struct
13215 `text_pos *'; all callers changed. Support display properties on
13217 (compute_display_string_end): Support display properties on Lisp
13219 (init_iterator, reseat_1, reseat_to_string): Initialize the
13220 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS

13223 Fix calculation of the object to scan. Fixes an error when using
13225 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
13226 base_level_stop; instead, set base_level_stop to BEGV.
13227 Fixes crashes in vertical-motion.
13228 (next_element_from_buffer): Improve commentary for when
13229 the iterator is before prev_stop.
13230 (init_iterator): Initialize bidi_p from the default value of

13253 parts of next_element_from_buffer, next_element_from_string, and
13254 next_element_from_c_string.

13256 (display_menu_bar): Force left-to-right direction. Add a FIXME
13257 comment for making that be controlled by a user option.

13266 (get_overlay_strings_1, push_display_prop): Set up the bidi
13267 iterator for displaying display or overlay strings.
13268 (forward_to_next_line_start): Don't use the shortcut if
13270 (back_to_previous_visible_line_start): If handle_display_prop
13271 pushed the iterator stack, restore the internal state of the bidi
13272 iterator by calling bidi_pop_it same number of times.
13273 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
13274 and we are bidi-iterating, don't decrement the iterator position;
13275 instead, set the first_elt flag in the bidi iterator, to produce
13277 (reseat_1): Remove redundant setting of string_from_display_prop_p.
13278 (push_display_prop): xassert that we are iterating a buffer.
13279 (push_it, pop_it): Save and restore paragraph_embedding member.
13280 (handle_single_display_spec, next_overlay_string)

13282 (push_display_prop): Set up the `unibyte' member of bidi_it.string
13283 correctly. Don't assume unibyte strings are not bidi-reordered.

13292 property. Fix a typo in popping stretch info. Add an assertion
13293 for verifying that the iterator position is in sync with the bidi
13295 (handle_single_display_spec, get_overlay_strings_1)

13320 displayed in margins. (Bug#8133) (Bug#8867)
13321 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past

13345 Support iteration over a string.
13346 (bidi_set_sor_type, bidi_resolve_explicit_1)
13347 (bidi_resolve_explicit, bidi_type_of_next_char): ignore_bn_limit
13348 can now be zero (for strings); special values 0 and -1 were
13349 changed to -1 and -2, respectively.
13350 (bidi_char_at_pos): New function.
13351 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak):

13707 (clone_per_buffer_values): Don't assume that

13710 if Emacs is configured with --with-wide-int.
13711 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):

13748 Random fixes. E.g., (random) never returned negative values.
13749 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
13750 subseconds part to the entropy, as that's a bit more random.
13751 Prefer signed to unsigned, since the signedness doesn't matter and
13752 in general we prefer signed. When given a limit, use a
13753 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
13754 latter isn't right if USE_2_TAGS_FOR_INTS.
13755 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
13756 not 0..VALMASK. Don't discard "excess" bits that random () returns.

13766 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
13768 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
13769 This is more efficient than Ffile_directory_p and avoids a minor race.
13771 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
13773 * buffer.c (Foverlay_put): Say what the return value is
13776 * fileio.c (barf_or_query_if_file_exists): Check first if the file
13777 is a directory before asking whether to use the file name
13779 (barf_or_query_if_file_exists): Make the "File is a directory"
13780 error be more correct.
13782 * fns.c (Frequire): Remove the mention of the .gz files, since
13783 that's installation-specific, but keep the mention of
13784 `get-load-suffixes'.
13786 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
13788 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

13799 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
13800 Also (re)move comments that are misplaced or no longer relevant.
13802 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
13804 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

13861 minibuffer-local-must-match-map, and
13862 minibuffer-local-filename-must-match-map to Elisp.
13863 (syms_of_keymap): Defsubr make-composed-keymap.
13864 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

13867 2011-07-01 Glenn Morris <rgm@gnu.org>
13869 * Makefile.in (SETTINGS_LIBS): Fix typo.
13871 2011-07-01 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny change)

13876 2011-07-01 Jan Djärv <jan.h.d@swipnet.se>
13878 * xsettings.c (store_monospaced_changed): Take new font as arg and
13879 check for change against current_mono_font.
13880 (EMACS_TYPE_SETTINGS): Remove this and related defines.
13881 (emacs_settings_constructor, emacs_settings_get_property)

13899 2011-07-01 Paul Eggert <eggert@cs.ucla.edu>
13901 * eval.c (struct backtrace): Simplify and port the data structure.
13902 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
13903 signed bit field, as this assumption is not portable and it makes
13904 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
13905 "char debug_on_exit : 1" as this is not portable either; instead,
13906 use the portable "unsigned int debug_on_exit : 1". Remove unused
13907 member evalargs. Remove obsolete comments about cc bombing out.
13909 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>
13911 * xsettings.c: Include glib-object.h, gio/gio.h if HAVE_GSETTINGS.

13952 the overlay's window property doesn't match the current window.
13954 * window.c (Fwindow_vchild): Rename to Fwindow_top_child.
13955 (Fwindow_hchild): Rename to Fwindow_left_child.

13977 (emacs_fixed_new): Set priv->f to argument.
13978 (emacs_fixed_get_preferred_width)
13979 (emacs_fixed_get_preferred_height): Use min_width/height from
13980 frames size_hint to set minimum and natural (Bug#8919).
13981 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
13982 and use min_width/height from frames size_hint to set
13983 min_width/height (Bug#8919).
13985 * gtkutil.c (xg_create_frame_widgets): Pass f to emacs_fixed_new.

14003 Use gnulib's dup2 module instead of rolling our own.
14004 * sysdep.c (dup2) [!HAVE_DUP2]: Remove; gnulib now does this.
14006 2011-06-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14008 * dispnew.c (scrolling_window): Before scrolling, turn off a

14071 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
14073 Integer and buffer overflow fixes (Bug#8873).
14075 * print.c (printchar, strout): Check for string overflow.
14076 (PRINTPREPARE, printchar, strout):
14077 Don't set size unless allocation succeeds.
14079 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
14080 for sizes. Check for string overflow more accurately.
14081 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
14083 * macros.c: Integer and buffer overflow fixes.
14084 * keyboard.h (struct keyboard.kbd_macro_bufsize):
14085 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):
14086 Use ptrdiff_t, not int, for sizes.

14088 Check for size-calculation overflow.
14089 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
14091 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
14093 * lread.c: Integer overflow fixes.
14094 (read_integer): Radix is now EMACS_INT, not int,
14095 to improve quality of diagnostics for out-of-range radices.
14096 Calculate buffer size correctly for out-of-range radices.
14097 (read1): Check for integer overflow in radices, and in
14098 read-circle numbers.
14099 (read_escape): Avoid int overflow.
14100 (Fload, openp, read_buffer_size, read1)
14101 (substitute_object_recurse, read_vector, read_list, map_obarray):
14102 Use ptrdiff_t, not int, for sizes.
14103 (read1): Use EMACS_INT, not int, for sizes.
14104 Check for size overflow.
14106 * image.c (cache_image): Check for size arithmetic overflow.

14115 (read_escape): Check for hex character overflow.
14117 2011-06-22 Leo Liu <sdl.web@gmail.com>
14119 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
14120 Move to minibuffer.el.
14122 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
14124 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
14125 The following patches are for when GLYPH_DEBUG && !XASSERT.
14126 * dispextern.h (trace_redisplay_p, dump_glyph_string):
14127 * dispnew.c (flush_stdout):
14128 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
14129 Mark as externally visible.
14130 * dispnew.c (check_window_matrix_pointers): Now static.
14131 * dispnew.c (window_to_frame_vpos):
14132 * xfns.c (unwind_create_frame):
14133 * xterm.c (x_check_font): Remove unused local.
14134 * scroll.c (CHECK_BOUNDS):
14135 * xfaces.c (cache_fache): Rename local to avoid shadowing.
14136 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
14137 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
14138 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
14139 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
14141 (debug_method_add): Use va_list and vsprintf rather than relying
14142 on undefined behavior with wrong number of arguments.
14143 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
14144 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
14145 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
14146 since we're not interested in debugging glyphs with old libraries.
14147 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
14148 GCC 4.6.0's static checking.
14150 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
14152 Integer overflow and signedness fixes (Bug#8873).
14153 A few related buffer overrun fixes, too.

14161 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
14162 (x_create_bitmap_from_xpm_data):
14163 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
14164 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
14166 * xfaces.c (load_pixmap):
14167 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
14168 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
14169 (.bitmaps_last, struct x_output.icon_bitmap):
14170 Use ptrdiff_t, not int, for bitmap indexes.
14171 (x_allocate_bitmap_record): Check for size overflow.
14172 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
14174 Use ptrdiff_t, not int, for overlay counts.
14175 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
14176 * editfns.c (overlays_around, get_pos_property):
14177 * textprop.c (get_char_property_and_overlay):
14178 * xdisp.c (next_overlay_change, note_mouse_highlight):
14179 * xfaces.c (face_at_buffer_position):
14180 * buffer.c (OVERLAY_COUNT_MAX): New macro.
14181 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
14182 (Fnext_overlay_change, Fprevious_overlay_change)
14183 (mouse_face_overlay_overlaps, Foverlays_in):
14184 Use ptrdiff_t, not int, for sizes.
14185 (overlays_at, overlays_in): Check for size-calculation overflow.
14187 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
14189 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
14190 (x_session_initialize): Do not assume string length fits in int.
14192 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
14193 This is unlikely, but can occur if DPI is outlandish.
14195 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
14196 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
14198 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
14199 * xrdb.c (magic_file_p, search_magic_path):
14200 Omit last arg SUFFIX; it was always 0. All callers changed.
14201 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
14203 * xfont.c (xfont_match): Avoid need for strlen.
14205 * xfns.c: Don't assume strlen fits in int.
14206 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
14208 * xdisp.c (message_log_check_duplicate): Return intmax_t,
14209 not unsigned long, as we prefer signed integers. All callers changed.
14210 Detect integer overflow in repeat count.
14211 (message_dolog): Don't assume print length fits in 39 bytes.
14212 (display_mode_element): Don't assume strlen fits in int.
14214 * termcap.c: Don't assume sizes fit in int and never overflow.
14215 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
14216 (gobble_line): Check for size-calculation overflow.
14218 * minibuf.c (Fread_buffer):
14219 * lread.c (intern, intern_c_string):
14220 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
14221 Don't assume string length fits in int.
14223 * keyboard.c (parse_tool_bar_item):
14224 * gtkutil.c (style_changed_cb): Avoid need for strlen.
14226 * font.c: Don't assume string length fits in int.
14227 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
14228 Use ptrdiff_t, not int.
14229 (font_intern_prop): Don't assume string length fits in int.
14230 Don't assume integer property fits in fixnum.
14231 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
14233 * filelock.c: Fix some buffer overrun and integer overflow issues.
14234 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
14235 Reformulate so as not to need the command string.
14236 Invoke gzip -cd rather than gunzip, as it's more portable.
14237 (lock_info_type, lock_file_1, lock_file):
14238 Don't assume pid_t and time_t fit in unsigned long.
14239 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
14240 (current_lock_owner): Prefer signed type for sizes.
14241 Use memcpy, not strncpy, where memcpy is what is really wanted.
14242 Don't assume (via atoi) that time_t and pid_t fit in int.
14243 Check for time_t and/or pid_t out of range, e.g., via a network share.
14244 Don't alloca where an auto var works fine.
14246 * fileio.c: Fix some integer overflow issues.
14247 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
14248 Don't assume string length fits in int.
14249 (directory_file_name): Don't assume string length fits in long.
14250 (make_temp_name): Don't assume pid fits in int, or that its print
14251 length is less than 20.
14253 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
14255 * coding.c (make_subsidiaries): Don't assume string length fits in int.
14257 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
14259 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
14260 We prefer signed integers, even for size calculations.
14262 * emacs.c: Don't assume string length fits in 'int'.
14263 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
14264 (main): Don't invoke strlen when not needed.
14266 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
14267 (XD_DEBUG_MESSAGE): Don't waste a byte.
14269 * callproc.c (getenv_internal_1, getenv_internal)
14270 (Fgetenv_internal):
14271 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
14273 * lread.c (invalid_syntax): Omit length argument.
14274 All uses changed. This doesn't fix a bug, but it simplifies the
14275 code away from its former Hollerith-constant appearance, and it's
14276 one less 'int' to worry about when looking at integer-overflow issues.
14277 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
14279 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
14280 This didn't break anything, but it didn't help either.
14281 It's confusing to put a bogus integer in a place where the actual
14282 value does not matter.
14283 (LIST_END_P): Remove unused macro and its bogus comment.
14284 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
14286 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
14287 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
14289 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
14290 We prefer signed types, and the value cannot exceed the EMACS_INT
14291 range anyway (because otherwise the length would not be representable).
14292 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
14293 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
14294 This avoids a GCC warning when WIDE_EMACS_INT.
14296 * indent.c (sane_tab_width): New function.
14297 (current_column, scan_for_column, Findent_to, position_indentation)
14298 (compute_motion): Use it. This is just for clarity.
14299 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
14301 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
14303 * lisp.h (lint_assume): New macro.
14304 * composite.c (composition_gstring_put_cache):
14305 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
14307 * editfns.c, insdel.c:
14308 Omit unnecessary forward decls, to simplify future changes.
14310 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
14312 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
14314 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
14315 Use much-faster test for byte-length change.
14316 Don't assume string byte-length fits in 'int'.
14317 Check that character arg fits in 'int'.
14318 (mapcar1): Declare byte as byte, for clarity.
14320 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
14322 * fns.c (concat): Catch string overflow earlier.
14323 Do not rely on integer wraparound.
14325 * dispextern.h (struct it.overlay_strings_charpos)
14326 (struct it.selective): Now EMACS_INT, not int.
14327 * xdisp.c (forward_to_next_line_start)
14328 (back_to_previous_visible_line_start)
14329 (reseat_at_next_visible_line_start, next_element_from_buffer):
14330 Don't arbitrarily truncate the value of 'selective' to int.
14332 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
14334 * composite.c: Don't truncate sizes to 'int'.
14335 (composition_gstring_p, composition_reseat_it)
14336 (composition_adjust_point): Use EMACS_INT, not int.
14337 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
14338 not EMACS_UINT, for indexes.
14340 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
14342 * buffer.c: Include <verify.h>.
14343 (struct sortvec.priority, struct sortstr.priority):
14344 Now EMACS_INT, not int.
14345 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
14346 (struct sortstr.size, record_overlay_string)
14347 (struct sortstrlist.size, struct sortlist.used):
14348 Don't truncate size to int.
14349 (record_overlay_string): Check for size-calculation overflow.
14350 (init_buffer_once): Check at compile-time, not run-time.
14352 2011-06-22 Jim Meyering <meyering@redhat.com>
14354 Don't leak an XBM-image-sized buffer
14355 * image.c (xbm_load): Free the image buffer after using it.
14357 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
14360 * composite.c (find_automatic_composition): Omit needless 'return 0;'
14361 that Sun C diagnosed.
14362 * fns.c (secure_hash): Fix pointer signedness issue.
14363 * intervals.c (static_offset_intervals): New function.
14364 (offset_intervals): Use it.
14366 2011-06-21 Leo Liu <sdl.web@gmail.com>
14369 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
14372 * fns.c (secure_hash): Rename from crypto_hash_function and change
14373 the first arg to accept symbols.
14374 (Fsecure_hash): New primitive.
14375 (syms_of_fns): New symbols.
14377 2011-06-20 Deniz Dogan <deniz@dogan.se>
14379 * process.c (Fset_process_buffer): Clarify return value in
14382 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
14384 * dispnew.c (add_window_display_history): Use BVAR.
14386 * xdisp.c (debug_method_add): Use BVAR.
14387 (check_window_end, dump_glyph_matrix, dump_glyph)
14388 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
14390 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
14393 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
14394 check till after the cache is created in init_frame_faces.
14396 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
14398 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
14400 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
14402 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
14403 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
14404 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
14406 Improve buffer-overflow checking (Bug#8873).
14407 * fileio.c (Finsert_file_contents):
14408 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
14409 Remove the old (too-loose) buffer overflow checks.
14410 They weren't needed, since make_gap checks for buffer overflow.
14411 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
14412 The old code merely checked for Emacs fixnum overflow, and relied
14413 on undefined (wraparound) behavior. The new code avoids undefined
14414 behavior, and also checks for ptrdiff_t and/or size_t overflow.
14416 * editfns.c (Finsert_char): Don't dump core with very negative counts.
14417 Tune. Don't use wider integers than needed. Don't use alloca.
14418 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
14420 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
14422 * insdel.c, lisp.h (buffer_overflow): New function.
14423 (insert_from_buffer_1, replace_range, replace_range_2):
14424 * insdel.c (make_gap_larger):
14425 * editfns.c (Finsert_char):
14426 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
14428 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
14430 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
14432 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
14434 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
14435 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
14437 * fileio.c: Don't assume EMACS_INT fits in off_t.
14438 (emacs_lseek): New static function.
14439 (Finsert_file_contents, Fwrite_region): Use it.
14440 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
14442 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
14444 * fns.c: Don't overflow int when computing a list length.
14445 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
14446 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
14447 truncation on 64-bit hosts. Check for QUIT every
14448 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
14449 faster and is responsive enough.
14450 (Flength): Report an error instead of overflowing an integer.
14451 (Fsafe_length): Return a float if the value is not representable
14452 as a fixnum. This shouldn't happen except in contrived situations.
14453 (Fnthcdr, Fsort): Don't assume list length fits in int.
14454 (Fcopy_sequence): Don't assume vector length fits in int.
14456 * alloc.c: Check that resized vectors' lengths fit in fixnums.
14457 (header_size, word_size): New constants.
14458 (allocate_vectorlike): Don't check size overflow here.
14459 (allocate_vector): Check it here instead, since this is the only
14460 caller of allocate_vectorlike that could cause overflow.
14461 Check that the new vector's length is representable as a fixnum.
14463 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
14464 The previous code was bogus. For example, next_almost_prime (32)
14465 returned 39, which is undesirable as it is a multiple of 3; and
14466 next_almost_prime (24) returned 25, which is a multiple of 5 so
14467 why was the code bothering to check for multiples of 7?
14469 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
14471 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
14473 Variadic C functions now count arguments with ptrdiff_t.
14474 This partly undoes my 2011-03-30 change, which replaced int with size_t.
14475 Back then I didn't know that the Emacs coding style prefers signed int.
14476 Also, in the meantime I found a few more instances where arguments
14477 were being counted with int, which may truncate counts on 64-bit
14478 machines, or EMACS_INT, which may be unnecessarily wide.
14479 * lisp.h (struct Lisp_Subr.function.aMANY)
14480 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
14481 Arg counts are now ptrdiff_t, not size_t.
14482 All variadic functions and their callers changed accordingly.
14483 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
14484 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
14485 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
14486 * callint.c (Fcall_interactively): Check arg count for overflow,
14487 to avoid potential buffer overrun. Use signed char, not 'int',
14488 for 'varies' array, so that we needn't bother to check its size
14489 calculation for overflow.
14490 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
14491 * eval.c (apply_lambda):
14492 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
14493 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
14494 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
14496 * callint.c (Fcall_interactively): Don't use index var as event count.
14498 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
14499 * mem-limits.h (SIZE): Remove; no longer used.
14501 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
14503 Remove unnecessary casts.
14504 * xterm.c (x_term_init):
14505 * xfns.c (x_set_border_pixel):
14506 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
14507 These aren't needed now that we assume ANSI C.
14509 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
14510 It's more likely to cause problems (due to unsigned overflow)
14513 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
14515 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
14517 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
14519 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
14521 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
14523 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
14525 GLYPH_CODE_FACE returns EMACS_INT, not int.
14526 * dispextern.h (merge_faces):
14527 * xfaces.c (merge_faces):
14528 * xdisp.c (get_next_display_element, next_element_from_display_vector):
14529 Don't assume EMACS_INT fits in int.
14531 * character.h (CHAR_VALID_P): Remove unused parameter.
14532 * fontset.c, lisp.h, xdisp.c: All uses changed.
14534 * editfns.c (Ftranslate_region_internal): Omit redundant test.
14536 * fns.c (concat): Minor tuning based on overflow analysis.
14537 This doesn't fix any bugs. Use int to hold character, instead
14538 of constantly refetching from Emacs object. Use XFASTINT, not
14539 XINT, for value known to be a character. Don't bother comparing
14540 a single byte to 0400, as it's always less.
14542 * floatfns.c (Fexpt):
14543 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
14545 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
14548 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
14550 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
14551 Without this fix, on a 64-bit host (aset S 0 4294967386) would
14552 incorrectly succeed when S was a string, because 4294967386 was
14553 truncated before it was used.
14555 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
14556 Otherwise, an out-of-range integer could cause undefined behavior
14559 * composite.c: Use int, not EMACS_INT, for characters.
14560 (fill_gstring_body, composition_compute_stop_pos): Use int, not
14561 EMACS_INT, for values that are known to be in character range.
14562 This doesn't fix any bugs but is the usual style inside Emacs and
14563 may generate better code on 32-bit machines.
14565 Make sure a 64-bit char is never passed to ENCODE_CHAR.
14566 This is for reasons similar to the recent CHAR_STRING fix.
14567 * charset.c (Fencode_char): Check that character arg is actually
14568 a character. Pass an int to ENCODE_CHAR.
14569 * charset.h (ENCODE_CHAR): Verify that the character argument is no
14570 wider than 'int', as a compile-time check to prevent future regressions
14573 * character.c (char_string): Remove unnecessary casts.
14575 Make sure a 64-bit char is never passed to CHAR_STRING.
14576 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
14577 by silently ignoring the top 32 bits, allowing some values
14578 that were far too large to be valid characters.
14579 * character.h: Include <verify.h>.
14580 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
14581 arguments are no wider than unsigned, as a compile-time check
14582 to prevent future regressions in this area.
14584 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
14585 (Fsubst_char_in_region):
14587 * xdisp.c (decode_mode_spec_coding):
14588 Adjust to CHAR_STRING's new requirement.
14589 * editfns.c (Finsert_char, Fsubst_char_in_region):
14590 * fns.c (concat): Check that character args are actually
14591 characters. Without this test, these functions did the wrong
14592 thing with wildly out-of-range values on 64-bit hosts.
14594 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
14595 These casts should not be needed on 32-bit hosts, either.
14596 * keyboard.c (read_char):
14597 * lread.c (Fload): Remove casts to unsigned.
14599 * lisp.h (UNSIGNED_CMP): New macro.
14600 This fixes comparison bugs on 64-bit hosts.
14601 (ASCII_CHAR_P): Use it.
14602 * casefiddle.c (casify_object):
14603 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
14604 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
14605 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
14606 * dispextern.h (FACE_FROM_ID):
14607 * keyboard.c (read_char): Use UNSIGNED_CMP.
14609 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
14610 not to EMACS_INT, to avoid GCC warning.
14612 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
14614 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
14615 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
14616 isn't needed on 32-bit machines.
14618 * buffer.c (Fgenerate_new_buffer_name):
14619 Use EMACS_INT for count, not int.
14620 (advance_to_char_boundary): Return EMACS_INT, not int.
14622 * data.c (Qcompiled_function): Now static.
14624 * window.c (window_body_lines): Now static.
14626 * image.c (gif_load): Rename local to avoid shadowing.
14628 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
14629 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
14630 * alloc.c (make_save_value): Integer argument is now of type
14631 ptrdiff_t, not int.
14632 (mark_object): Use ptrdiff_t, not int.
14633 * lisp.h (pD): New macro.
14634 * print.c (print_object): Use it.
14636 * alloc.c: Use EMACS_INT, not int, to count objects.
14637 (total_conses, total_markers, total_symbols, total_vector_size)
14638 (total_free_conses, total_free_markers, total_free_symbols)
14639 (total_free_floats, total_floats, total_free_intervals)
14640 (total_intervals, total_strings, total_free_strings):
14641 Now EMACS_INT, not int. All uses changed.
14642 (Fgarbage_collect): Compute overall total using a double, so that
14643 integer overflow is less likely to be a problem. Check for overflow
14644 when converting back to an integer.
14645 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
14646 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
14647 These were 'int' variables that could overflow on 64-bit hosts;
14648 they were never used, so remove them instead of repairing them.
14649 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
14650 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
14651 Previously, this ceilinged at INT_MAX, but that doesn't work on
14653 (allocate_pseudovector): Don't use EMACS_INT when int would do.
14655 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
14656 (allocate_vectorlike): Check for ptrdiff_t overflow.
14657 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
14658 when a (possibly-narrower) signed value would do just as well.
14659 We prefer using signed arithmetic, to avoid comparison confusion.
14661 * alloc.c: Catch some string size overflows that we were missing.
14662 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
14663 for convenience in STRING_BYTES_MAX.
14664 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
14665 The definition here is exact; the one in lisp.h was approximate.
14666 (allocate_string_data): Check for string overflow. This catches
14667 some instances we weren't catching before. Also, it catches
14668 size_t overflow on (unusual) hosts where SIZE_MAX <= min
14669 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
14670 and ptrdiff_t and EMACS_INT are both 64 bits.
14672 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
14673 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
14674 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
14676 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
14678 * alloc.c (Fmake_string): Check for out-of-range init.
14680 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
14682 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
14684 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
14686 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
14687 xg_get_default_scrollbar_width.
14689 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
14690 (int_gtk_range_get_value): Move to the scroll bar part of the file.
14691 (style_changed_cb): Call update_theme_scrollbar_width and call
14692 x_set_scroll_bar_default_width and xg_frame_set_char_size for
14693 all frames (Bug#8505).
14694 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
14695 Call gtk_window_set_resizable if HAVE_GTK3.
14696 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
14697 and height if HAVE_GTK3 (Bug#8505).
14698 (scroll_bar_width_for_theme): New variable.
14699 (update_theme_scrollbar_width): New function.
14700 (xg_get_default_scrollbar_width): Move code to
14701 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
14702 (xg_initialize): Call update_theme_scrollbar_width.
14704 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
14706 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
14708 2011-06-12 Martin Rudalics <rudalics@gmx.at>
14710 * frame.c (make_frame): Call other_buffer_safely instead of
14713 * window.c (temp_output_buffer_show): Call display_buffer with
14714 second argument Vtemp_buffer_show_specifiers and reset latter
14715 immediately after the call.
14716 (Vtemp_buffer_show_specifiers): New variable.
14717 (auto_window_vscroll_p, next_screen_context_lines)
14718 (Vscroll_preserve_screen_position): Remove leading asterisks from
14721 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
14723 Fix minor problems found by GCC 4.6.0 static checking.
14724 * buffer.c (Qclone_number): Remove for now, as it's unused.
14725 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
14726 (record_buffer): Remove unused local.
14727 * frame.c (other_visible_frames, frame_buffer_list): Now static.
14728 (set_frame_buffer_list): Remove; unused.
14729 * frame.h (other_visible_frames): Remove decl.
14730 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
14731 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
14732 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
14734 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
14735 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
14736 Define only if HAVE_GPM.
14737 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.

15201 min width by calling x_set_scroll_bar_default_width (Bug#8505).
15203 2011-06-05 Juanma Barranquero <lekktu@gmail.com>
15205 * xdisp.c (single_display_spec_intangible_p): Remove declaration.
15207 2011-06-04 Chong Yidong <cyd@stupidchicken.com>

15212 New error handlers.
15213 (x_clipboard_manager_save_frame, x_clipboard_manager_save_all):
15214 Obey Vx_select_enable_clipboard_manager. Catch errors in
15215 x_clipboard_manager_save (Bug#8779).
15216 (Vx_select_enable_clipboard_manager): New variable.
15217 (x_get_foreign_selection): Reduce scope of x_catch_errors (Bug#8790).
15219 2011-06-04 Dan Nicolaescu <dann@ics.uci.edu>
15221 * emacs.c (main): Warn when starting a GTK emacs in daemon mode.
15223 2011-06-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15225 * fringe.c (update_window_fringes): Don't update overlay arrow bitmap
15226 in the current matrix if keep_current_p is non-zero.

15230 * bidi.c (bidi_level_of_next_char): Fix last change.
15232 2011-06-03 Eli Zaretskii <eliz@gnu.org>
15234 Support bidi reordering of text covered by display properties.
15236 * bidi.c (bidi_copy_it): Use offsetof instead of emulating it.
15237 (bidi_fetch_char, bidi_fetch_char_advance): New functions.
15238 (bidi_cache_search, bidi_cache_iterator_state)
15239 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
15240 (bidi_level_of_next_char, bidi_move_to_visually_next):
15241 Support character positions inside a run of characters covered by a
15243 (bidi_paragraph_init, bidi_resolve_explicit_1)
15244 (bidi_level_of_next_char): Call bidi_fetch_char and
15245 bidi_fetch_char_advance instead of FETCH_CHAR and
15246 FETCH_CHAR_ADVANCE.
15247 (bidi_init_it): Initialize new members.
15248 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
15250 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
15251 instead of using explicit *_CHAR codes.
15252 (bidi_resolve_explicit, bidi_resolve_weak):
15253 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
15254 bidirectional text is supported only in multibyte buffers.
15255 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
15256 it to initialize the frame_window_p member of struct bidi_it.
15257 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
15258 (bidi_resolve_explicit, bidi_resolve_weak)

15260 bidi_it->nchars is non-positive.
15261 (bidi_level_of_next_char): Don't try to lookup the cache for the
15262 next/previous character if nothing is cached there yet, or if we
15263 were just reseat()'ed to a new position.
15265 * xdisp.c (set_cursor_from_row): Set start and stop points
15266 according to the row's direction when priming the loop that looks
15267 for the glyph on which to display cursor.
15268 (single_display_spec_intangible_p): Function deleted.
15269 (display_prop_intangible_p): Reimplement to call
15270 handle_display_spec instead of single_display_spec_intangible_p.
15271 Accept 3 additional arguments needed by handle_display_spec.
15272 This fixes incorrect cursor motion across display property with complex
15273 values: lists, `(when COND...)' forms, etc.
15274 (single_display_spec_string_p): Support property values that are
15275 lists with the argument STRING its top-level element.
15276 (display_prop_string_p): Fix the condition for processing a
15277 property that is a list to be consistent with handle_display_spec.
15278 (handle_display_spec): New function, refactored from the
15279 last portion of handle_display_prop.
15280 (compute_display_string_pos): Accept additional argument
15281 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
15282 value of a `display' property is a "replacing spec".
15283 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
15284 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
15285 the display property, but just return a value indicating whether
15286 the display property will replace the characters it covers.
15287 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
15288 frame_window_p members of struct bidi_it.
15289 (compute_display_string_pos, compute_display_string_end):
15291 (push_it): Accept second argument POSITION, where pop_it should
15292 jump to continue iteration.
15293 (reseat_1): Initialize bidi_it.disp_pos.
15295 * keyboard.c (adjust_point_for_property): Adjust the call to
15296 display_prop_intangible_p to its new signature.
15298 * dispextern.h (struct bidi_it): New member frame_window_p.
15299 (bidi_init_it): Update prototypes.
15300 (display_prop_intangible_p): Update prototype.
15301 (compute_display_string_pos, compute_display_string_end):
15302 Declare prototypes.
15303 (struct bidi_it): New members nchars and disp_pos. ch_len is now
15306 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
15308 Malloc failure behavior now depends on size of allocation.
15309 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
15310 * lisp.h: Change signatures accordingly.
15311 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
15312 All callers changed. (Bug#8762)
15314 * gnutls.c: Use Emacs's memory allocators.
15315 Without this change, the gnutls library would invoke malloc etc.
15316 directly, which causes problems on non-SYNC_INPUT hosts, and which
15317 runs afoul of improving memory_full behavior. (Bug#8761)
15318 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
15319 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
15320 xfree instead of the default malloc, realloc, free.
15321 (Fgnutls_boot): No need to check for memory allocation failure,
15322 since xmalloc does that for us.
15324 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
15325 * category.c (hash_get_category_set):
15326 * ccl.c (ccl_driver):
15327 * charset.c (Fdefine_charset_internal):
15328 * charset.h (struct charset.hash_index):

15330 (composition_gstring_put_cache):
15331 * composite.h (struct composition.hash_index):
15332 * dispextern.h (struct image.hash):

15334 (cmpfn_equal, cmpfn_user_defined, hashfn_eq, hashfn_eql)
15335 (hashfn_equal, hashfn_user_defined, make_hash_table)
15336 (maybe_resize_hash_table, hash_lookup, hash_put)
15337 (hash_remove_from_table, hash_clear, sweep_weak_table, SXHASH_COMBINE)
15338 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
15339 (Fsxhash, Fgethash, Fputhash, Fmaphash):
15340 * image.c (make_image, search_image_cache, lookup_image)
15341 (xpm_put_color_table_h):
15342 * lisp.h (struct Lisp_Hash_Table):
15343 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
15344 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
15345 for hashes and hash indexes, instead of 'unsigned' and 'int'.
15346 * alloc.c (allocate_vectorlike):
15347 Check for overflow in vector size calculations.
15348 * ccl.c (ccl_driver):
15349 Check for overflow when converting EMACS_INT to int.
15350 * fns.c, image.c: Remove unnecessary static decls that would otherwise
15351 need to be updated by these changes.
15352 * fns.c (make_hash_table, maybe_resize_hash_table):
15353 Check for integer overflow with large hash tables.
15354 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
15355 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
15356 (SXHASH_REDUCE): New macro.
15357 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
15358 Use it instead of discarding useful hash info with large hash values.
15359 (sxhash_float): New function.
15360 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
15361 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
15362 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
15363 Rewrite to use FIXNUM_BITS, as this simplifies things.
15364 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
15365 Adjust signatures to match updated version of code.
15366 (consing_since_gc): Now EMACS_INT, since a single hash table can
15367 use more than INT_MAX bytes.
15369 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
15371 Make it possible to build with GCC-4.6+ -O2 -flto.
15373 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
15375 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
15377 * minibuf.c (get_minibuffer, read_minibuf_unwind):
15378 Call minibuffer-inactive-mode.
15380 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
15382 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
15383 Update dependencies.
15385 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
15387 * data.c (init_data): Remove code for UTS, this system is not
15390 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
15392 Don't force ./temacs to start in terminal mode.
15394 * frame.c (make_initial_frame): Initialize faces in all cases, not
15395 only when CANNOT_DUMP is defined.
15396 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
15398 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
15400 * dispnew.c (add_window_display_history): Use const for the string
15401 pointer. Remove declaration, not needed.
15403 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
15405 Use 'inline', not 'INLINE'.
15406 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
15407 * alloc.c, fontset.c (INLINE): Remove.
15408 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
15409 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
15410 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
15411 * gmalloc.c (register_heapinfo): Use inline unconditionally.
15412 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
15414 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
15416 Make it possible to run ./temacs.
15418 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
15419 syms_of_callproc does the same thing. Remove test for
15420 "initialized", do it in the caller.
15421 * emacs.c (main): Avoid calling set_initial_environment when dumping.
15423 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
15425 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
15426 (read_minibuf): Use get_minibuffer.
15427 (syms_of_minibuf): Use DEFSYM.
15428 (Qmetadata): New var.
15429 * data.c (Qbuffer): Don't make it static.
15430 (syms_of_data): Use DEFSYM.
15432 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
15434 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
15435 (CCL_CODE_MIN): New macro.
15437 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
15439 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
15441 * eval.c (Qdebug): Now static.
15442 * lisp.h (Qdebug): Remove decl. This reverts a part of the
15443 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
15444 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
15446 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
15448 * image.c: Various fixes to ImageMagick code comments.
15449 (Fimagemagick_types): Doc fix.
15451 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
15453 Minor fixes prompted by GCC 4.6.0 warnings.
15455 * xselect.c (converted_selections, conversion_fail_tag): Now static.
15457 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
15458 (x_clipboard_manager_save_all): Move extern decl to ...
15459 * xterm.h: ... here, so that it can be checked for consistency.
15461 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
15463 * xselect.c (x_clipboard_manager_save_frame)
15464 (x_clipboard_manager_save_all): New functions.
15465 (Fx_clipboard_manager_save): Lisp function deleted.
15467 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
15468 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
15470 * xterm.h: Update prototype.
15472 2011-05-28 William Xu <william.xwl@gmail.com>
15474 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
15475 exiting (Bug#8239).
15477 2011-05-28 Jim Meyering <meyering@redhat.com>
15479 Avoid a sign-extension bug in crypto_hash_function.
15480 * fns.c (to_uchar): Define.
15481 (crypto_hash_function): Use it to convert some newly-signed
15482 variables to unsigned, to avoid sign-extension bugs. For example,
15483 without this change, (md5 "truc") would evaluate to
15484 45723a2aff78ff4fff7fff1114760e62 rather than the expected
15485 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
15486 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
15488 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
15490 Integer overflow fixes.
15492 * dbusbind.c: Serial number integer overflow fixes.
15493 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
15494 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
15495 to hold a serial number that is too large for a fixnum.
15496 (Fdbus_method_return_internal, Fdbus_method_error_internal):
15497 Check for serial numbers out of range. Decode any serial number
15498 that was so large that it became a float. (Bug#8722)
15500 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
15501 (Fdbus_call_method, Fdbus_call_method_asynchronously):
15502 Use XFASTINT rather than XUINT when numbers are nonnegative.
15503 (xd_append_arg, Fdbus_method_return_internal):
15504 (Fdbus_method_error_internal): Likewise. Also, for unsigned
15505 arguments, check that Lisp number is nonnegative, rather than
15506 silently wrapping negative numbers around. (Bug#8722)
15507 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
15510 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
15512 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
15514 ccl: Add integer overflow checks.
15515 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
15516 (IN_INT_RANGE): New macros.
15517 (ccl_driver): Use them to check for integer overflow when
15518 decoding a CCL program. Many of the new checks are whether XINT (x)
15519 fits in int; it doesn't always, on 64-bit hosts. The new version
15520 doesn't catch all possible integer overflows, but it's an
15521 improvement. (Bug#8719)
15523 * alloc.c (make_event_array): Use XINT, not XUINT.
15524 There's no need for unsigned here.
15526 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
15527 This follows up to the 2011-05-06 change that substituted uintptr_t
15528 for EMACS_INT. This case wasn't caught back then.
15530 Rework Fformat to avoid integer overflow issues.
15531 * editfns.c: Include <float.h> unconditionally, as it's everywhere
15532 now (part of C89). Include <verify.h>.
15533 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
15534 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
15535 (Fformat): Avoid the prepass trying to compute sizes; it was only
15536 approximate and thus did not catch overflow reliably. Instead, walk
15537 through the format just once, formatting and computing sizes as we go,
15538 checking for integer overflow at every step, and allocating a larger
15539 buffer as needed. Keep track separately whether the format is
15540 multibyte. Keep only the most-recently calculated precision, rather
15541 than them all. Record whether each argument has been converted to
15542 string. Use EMACS_INT, not int, for byte and char and arg counts.
15543 Support field widths and precisions larger than INT_MAX. Avoid
15544 sprintf's undefined behavior with conversion specifications such as %#d
15545 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
15546 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
15547 formatting out-of-range floating point numbers with int
15548 formats. (Bug#8668)
15550 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
15552 * data.c: Avoid integer truncation in expressions involving floats.
15553 * data.c: Include <intprops.h>.
15554 (arith_driver): When there's an integer overflow in an expression
15555 involving floating point, convert the integers to floating point
15556 so that the resulting value does not suffer from catastrophic
15557 integer truncation. For example, on a 64-bit host (* 4
15558 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
15559 Do not rely on undefined behavior after integer overflow.
15561 merge count_size_as_multibyte, parse_str_to_multibyte
15562 * character.c, character.h (count_size_as_multibyte):
15563 Rename from parse_str_to_multibyte; all uses changed.
15564 Check for integer overflow.
15565 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
15566 since it's now a duplicate of the other. This is more of
15567 a character than a buffer op, so better that it's in character.c.
15568 * fns.c, print.c: Adjust to above changes.
15570 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
15572 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
15574 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
15576 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
15577 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
15578 (x_clipboard_manager_save): Now static.
15579 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
15581 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
15582 (crypto_hash_function): Now static.
15583 Fix pointer signedness problems. Avoid unnecessary initializations.
15585 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
15587 * termhooks.h (Vselection_alist): Make it terminal-local.
15589 * terminal.c (create_terminal): Initialize it.
15591 * xselect.c: Support for clipboard managers.
15592 (Vselection_alist): Move to termhooks.h as terminal-local var.
15593 (LOCAL_SELECTION): New macro.
15594 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
15595 (symbol_to_x_atom): Remove gratuitous arg.
15596 (x_handle_selection_request, lisp_data_to_selection_data)
15597 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
15598 (x_own_selection, x_get_local_selection, x_convert_selection):
15599 New arg, specifying work frame. Use terminal-local Vselection_alist.
15600 (some_frame_on_display): Delete unused function.
15601 (Fx_own_selection_internal, Fx_get_selection_internal)
15602 (Fx_disown_selection_internal, Fx_selection_owner_p)
15603 (Fx_selection_exists_p): New optional frame arg.
15604 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
15605 (x_handle_selection_clear): Don't treat other terminals with the
15606 same keyboard specially. Use the terminal-local Vselection_alist.
15607 (x_clear_frame_selections): Use Frun_hook_with_args.
15609 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
15611 * xterm.h: Add support for those atoms.
15613 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
15615 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
15616 (converted_selections, conversion_fail_tag): New global variables.
15617 (x_selection_request_lisp_error): Free the above.
15618 (x_get_local_selection): Remove unnecessary code.
15619 (x_reply_selection_request): Args changed; handle arbitrary array
15620 of converted selections stored in converted_selections.
15621 Separate the XChangeProperty and SelectionNotify steps.
15622 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
15623 (x_convert_selection): New function.
15624 (x_handle_selection_event): Simplify.
15625 (x_get_foreign_selection): Don't ignore incoming requests while
15626 waiting for an answer; this will fail when we implement
15627 SAVE_TARGETS, and seems unnecessary anyway.
15628 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
15629 (Vx_sent_selection_functions): Doc fix.
15631 2011-05-26 Leo Liu <sdl.web@gmail.com>
15633 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
15635 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15637 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
15639 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
15640 for fringe update if it has periodic bitmap.
15641 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
15642 and fringe_bitmap_periodic_p.
15644 * fringe.c (get_fringe_bitmap_data): New function.
15645 (draw_fringe_bitmap_1, update_window_fringes): Use it.
15646 (update_window_fringes): Record periodicity of fringe bitmap in glyph
15647 row. Mark glyph row for fringe update if periodicity changed.
15649 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
15650 for fringe update unless it has periodic bitmap.
15652 2011-05-25 Kenichi Handa <handa@m17n.org>
15654 * xdisp.c (get_next_display_element): Set correct it->face_id for
15655 a static composition.
15657 2011-05-24 Leo Liu <sdl.web@gmail.com>
15660 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
15662 * fns.c (crypto_hash_function, Fsha1): New function.
15663 (Fmd5): Use crypto_hash_function.
15664 (syms_of_fns): Add Ssha1.
15666 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
15668 * gnutls.c: Remove unused macros.
15669 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
15670 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
15671 Remove macros that are defined and never used.
15672 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
15674 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
15676 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
15677 (Fx_get_selection_internal): Minor cleanup.
15678 (Fx_own_selection_internal): Rename arguments for consistency with
15681 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
15683 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
15685 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
15687 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
15689 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15691 * dispnew.c (scrolling_window): Don't exclude the case that the
15692 last enabled row in the desired matrix touches the bottom boundary.
15694 2011-05-21 Glenn Morris <rgm@gnu.org>
15696 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
15697 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
15698 and add some more files.
15700 2011-05-20 Eli Zaretskii <eliz@gnu.org>
15702 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
15703 report_file_error introduced by the change from 2011-05-07.
15705 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
15707 * systime.h (Time): Define only if emacs is defined.
15708 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
15709 where the include path doesn't have X11/X.h by default. See
15710 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
15712 2011-05-20 Kenichi Handa <handa@m17n.org>
15714 * composite.c (find_automatic_composition): Fix previous change.
15716 2011-05-20 Glenn Morris <rgm@gnu.org>
15718 * lisp.mk: New file, split from Makefile.in.
15719 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
15720 (shortlisp): Remove.
15721 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
15723 2011-05-19 Glenn Morris <rgm@gnu.org>
15725 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
15726 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
15727 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
15728 (lisp): Set the order to that of loadup.el.
15729 (shortlisp): Make it a copy of $lisp.
15730 (SOME_MACHINE_LISP): Remove.
15731 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
15732 Use just $shortlisp, not $SOME_MACHINE_LISP too.
15734 2011-05-18 Kenichi Handa <handa@m17n.org>
15736 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
15737 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
15738 (find_automatic_composition): Mostly rewrite for efficiency.
15740 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
15742 * makefile.w32-in: Update dependencies.
15744 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
15746 * menu.c: Include limits.h (fixes the MS-Windows build broken by
15747 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
15749 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
15751 Fix some integer overflow issues, such as string length overflow.
15753 * insdel.c (count_size_as_multibyte): Check for string overflow.
15755 * character.c (lisp_string_width): Check for string overflow.
15756 Use EMACS_INT, not int, for string indexes and lengths; in
15757 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
15758 the resulting string length overflows an EMACS_INT; instead,
15759 report a string overflow if no precision given. When checking for
15760 precision exhaustion, use a check that cannot possibly have
15761 integer overflow. (Bug#8675)
15762 * character.h (lisp_string_width): Adjust to new signature.
15764 * alloc.c (string_overflow): New function.
15765 (Fmake_string): Use it. This doesn't change behavior, but saves
15766 a few bytes and will simplify future changes.
15767 * character.c (string_escape_byte8): Likewise.
15768 * lisp.h (string_overflow): New decl.
15770 Fixups, following up to the user-interface timestamp change.
15771 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
15772 for UI timestamps, instead of unsigned long.
15773 * msdos.c (mouse_get_pos): Likewise.
15774 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
15775 * w32gui.h (Time): Define by including "systime.h" rather than by
15776 declaring it ourselves. (Bug#8664)
15778 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
15779 * image.c (clear_image_cache): Likewise.
15781 * term.c (term_mouse_position): Don't assume time_t wraparound.
15783 Be more systematic about user-interface timestamps.
15784 Before, the code sometimes used 'Time', sometimes 'unsigned long',
15785 and sometimes 'EMACS_UINT', to represent these timestamps.
15786 This change causes it to use 'Time' uniformly, as that's what X uses.
15787 This makes the code easier to follow, and makes it easier to catch
15788 integer overflow bugs such as Bug#8664.
15789 * frame.c (Fmouse_position, Fmouse_pixel_position):
15790 Use Time, not unsigned long, for user-interface timestamps.
15791 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
15792 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
15793 * keyboard.h (last_event_timestamp): Likewise.
15794 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
15795 * menu.h (xmenu_show): Likewise.
15796 * term.c (term_mouse_position): Likewise.
15797 * termhooks.h (struct input_event.timestamp): Likewise.
15798 (struct terminal.mouse_position_hook): Likewise.
15799 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
15800 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
15801 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
15802 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
15803 what it was before.
15804 * menu.h, termhooks.h: Include "systime.h", for Time.
15806 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
15807 Don't assume that the difference between two unsigned long values
15808 can fit into an integer. At this point, we know button_down_time
15809 <= event->timestamp, so the difference must be nonnegative, so
15810 there's no need to cast the result if double-click-time is
15811 nonnegative, as it should be; check that it's nonnegative, just in
15812 case. This bug is triggered when events are more than 2**31 ms
15813 apart (about 25 days). (Bug#8664)
15815 * xselect.c (last_event_timestamp): Remove duplicate decl.
15816 (x_own_selection): Remove needless cast to unsigned long.
15818 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
15819 that always fit in int. Use a sentinel instead of a counter, to
15820 avoid a temp and to allay GCC's concerns about possible int overflow.
15821 * frame.h (struct frame): Use int for menu_bar_items_used
15822 instead of EMACS_INT, since it always fits in int.
15824 * menu.c (grow_menu_items): Check for int overflow.
15826 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
15828 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
15829 Before, the code was not consistent. These values cannot exceed
15830 2**31 - 1 so there's no need to make them unsigned.
15831 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
15832 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
15833 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
15835 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
15837 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
15838 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
15839 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
15840 presumably because the widths might not match.
15842 * window.c (size_window): Avoid needless test at loop start.
15844 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
15846 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
15848 2011-05-12 Drew Adams <drew.adams@oracle.com>
15850 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
15852 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15854 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
15855 `width' to `bar_area_x' and `bar_area_width', respectively.
15856 (x_scroll_run): Take account of fringe background extension.
15858 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
15859 Rename local vars `left' and `width' to `bar_area_x' and
15860 `bar_area_width', respectively.
15861 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
15862 background extension.
15864 2011-05-10 Jim Meyering <meyering@redhat.com>
15866 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
15868 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
15870 * image.c (Finit_image_library): Return t for built-in image types,
15871 like pbm and xbm. (Bug#8640)
15873 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
15875 * w32menu.c (set_frame_menubar): Fix submenu allocation.
15877 2011-05-07 Eli Zaretskii <eliz@gnu.org>
15879 * w32console.c (Fset_screen_color): Doc fix.
15880 (Fget_screen_color): New function.
15881 (syms_of_ntterm): Defsubr it.
15883 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
15884 unlink the temporary file if Fcall_process didn't create it in the
15886 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
15887 child process will be redirected to a file specified with `:file'.
15888 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
15889 cue to call_process_cleanup not to close that handle.
15891 2011-05-07 Ben Key <bkey76@gmail.com>
15893 * makefile.w32-in: The bootstrap-temacs rule now makes use of
15894 one of two shell specific rules, either bootstrap-temacs-CMD or
15895 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
15896 to the previous implementation of the bootstrap-temacs rule.
15897 The bootstrap-temacs-CMD rule is similar to the previous
15898 implementation of the bootstrap-temacs rule except that it
15899 makes use of the ESC_CFLAGS variable instead of the CFLAGS
15902 These changes, along with some changes to nt/configure.bat,
15903 nt/gmake.defs, and nt/nmake.defs, are required to extend my
15904 earlier fix to add support for --cflags and --ldflags options
15905 that include quotes so that it works whether make uses cmd or
15908 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
15910 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
15911 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
15913 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
15914 a string. Handle both cases.
15915 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
15916 (Fdbus_register_method): Use Qinvalid_function.
15918 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
15920 * makefile.w32-in: Update dependencies.
15921 (LISP_H): Add inttypes.h and stdin.h.
15922 (PROCESS_H): Add unistd.h.
15924 2011-05-06 Eli Zaretskii <eliz@gnu.org>
15926 * lread.c: Include limits.h (fixes the MS-Windows build broken by
15927 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
15929 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
15931 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
15933 * term.c (vfatal): Remove stray call to va_end.
15934 It's not needed and the C Standard doesn't allow it here anyway.
15936 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
15937 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
15939 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
15942 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
15944 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
15946 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
15948 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
15950 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
15952 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
15953 * charset.c (Fdefine_charset_internal): Don't initialize
15954 charset.code_space[15]. The value was garbage, on hosts with
15955 32-bit int (Bug#8600).
15957 * lread.c (read_integer): Be more consistent with string-to-number.
15958 Use string_to_number to do the actual conversion; this avoids
15959 rounding errors and fixes some other screwups. Without this fix,
15960 for example, #x1fffffffffffffff was misread as -2305843009213693952.
15961 (digit_to_number): Move earlier, for benefit of read_integer.
15962 Return -1 if the digit is out of range for the base, -2 if it is
15963 not a digit in any supported base. (Bug#8602)
15965 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
15967 * dispnew.c (scrolling_window): Return 1 if we scrolled,
15968 to match comment at start of function. This also removes a
15969 GCC warning about overflow in a 32+64-bit port.
15971 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
15973 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
15974 Reported by Stefan Monnier in
15975 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
15976 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
15977 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
15979 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
15980 (EMACS_UINTPTR): Likewise, with uintptr_t.
15982 * lisp.h: Prefer 64-bit EMACS_INT if available.
15983 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
15984 on 32-bit hosts that have 64-bit int, so that they can access
15986 However, temporarily disable this change unless the temporary
15987 symbol WIDE_EMACS_INT is defined.
15989 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
15991 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
15992 This removes an assumption that EMACS_INT and long are the same
15993 width as pointers. The assumption is true for Emacs porting targets
15994 now, but we want to make other targets possible.
15995 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
15996 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
15997 In the rest of the code, change types of integers that hold casted
15998 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
15999 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
16000 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
16001 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
16002 No need to cast type when ORing.
16003 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
16004 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
16005 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
16006 assume EMACS_INT is the same width as char *.
16007 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
16008 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
16009 Remove no-longer-needed casts.
16010 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
16011 (xg_tool_bar_help_callback, xg_make_tool_item):
16012 Use EMACS_INTPTR to hold an integer
16013 that will be cast to void *; this can avoid a GCC warning
16014 if EMACS_INT is not the same width as void *.
16015 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
16016 * xdisp.c (display_echo_area_1, resize_mini_window_1):
16017 (current_message_1, set_message_1):
16018 Use a local to convert to proper width without a cast.
16019 * xmenu.c (dialog_selection_callback): Likewise.
16021 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
16022 Also, don't assume VALBITS / RAND_BITS is less than 5,
16023 and don't rely on undefined behavior when shifting a 1 left into
16025 * lisp.h (get_random): Change signature to match.
16027 * lread.c (hash_string): Use size_t, not int, for hash computation.
16028 Normally we prefer signed values; but hashing is special, because
16029 it's better to use unsigned division on hash table sizes so that
16030 the remainder is nonnegative. Also, size_t is the natural width
16031 for hashing into memory. The previous code used 'int', which doesn't
16032 retain enough info to hash well into very large tables.
16033 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
16035 * dbusbind.c: Don't possibly lose pointer info when converting.
16036 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
16037 Use XPNTR rather than XHASH, so that the high-order bits of
16038 the pointer aren't lost when converting through void *.

16125 * process.c: Include lisp.h before w32.h, not after.
16126 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
16127 instead of gnutls_record_check_pending.

16131 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
16133 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options

16210 produced by %s or %c overflows available buffer space. (Bug#8545)
16212 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
16214 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).

16217 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
16219 * w32.c (init_environment): Warn about defaulting HOME to C:\.
16221 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
16223 * keyboard.c (Qdelayed_warnings_hook): Define.
16224 (command_loop_1): Run `delayed-warnings-hook'
16225 if Vdelayed_warnings_list is non-nil.
16226 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
16227 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
16229 2011-04-28 Eli Zaretskii <eliz@gnu.org>
16231 * doprnt.c (doprnt): Don't return value smaller than the buffer
16232 size if the message was truncated. (Bug#8545).
16234 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
16236 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
16237 (Fx_window_property): #if-0 the whole functions, not just the bodies.
16239 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
16241 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
16243 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
16245 * makefile.w32-in: Update dependencies.
16247 2011-04-27 Eli Zaretskii <eliz@gnu.org>
16249 Improve `doprnt' and its usage. (Bug#8545)
16250 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
16251 `format_end'. Remove support for %l as a conversion specifier.
16252 Don't use xrealloc. Improve diagnostics when the %l size modifier
16253 is used. Update the commentary.
16255 * eval.c (verror): Simplify calculation of size_t.
16257 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
16260 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
16262 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
16265 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
16267 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
16268 This makes this file independent of the recent pseudovector change.
16270 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
16272 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
16274 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
16275 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
16276 Remove unused local.
16277 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
16279 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
16280 GCC 4.6.0 optimizes based on type-based alias analysis.
16281 For example, if b is of type struct buffer * and v of type struct
16282 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
16283 != &v->size, and therefore "v->size = 1; b->size = 2; return
16284 v->size;" must therefore return 1. This assumption is incorrect
16285 for Emacs, since it type-puns struct Lisp_Vector * with many other
16286 types. To fix this problem, this patch adds a new type struct
16287 vectorlike_header that documents the constraints on layout of vectors
16288 and pseudovectors, and helps optimizing compilers not get fooled
16289 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
16290 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
16291 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
16293 (XSETPVECTYPE): Rewrite in terms of new macro.
16294 (XSETPVECTYPESIZE): New macro, specifying both type and size.
16295 This is a bit clearer, and further avoids the possibility of
16296 undesirable aliasing.
16297 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
16298 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
16299 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
16300 since Lisp_Subr is a special case (no "next" field).
16301 (ASIZE): Now uses header.size rather than size.
16302 All previous uses of XVECTOR (foo)->size replaced to use this macro,
16303 to avoid the hassle of writing XVECTOR (foo)->header.size.
16304 (struct vectorlike_header): New type.
16305 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
16306 object, to help avoid aliasing.
16307 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
16308 (SUBRP): Likewise, since Lisp_Subr is a special case.
16309 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
16310 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
16311 (struct Lisp_Hash_Table): Combine first two members into a single
16312 struct vectorlike_header member. All uses of "size" and "next" members
16313 changed to be "header.size" and "header.next".
16314 * buffer.h (struct buffer): Likewise.
16315 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
16316 * frame.h (struct frame): Likewise.
16317 * process.h (struct Lisp_Process): Likewise.
16318 * termhooks.h (struct terminal): Likewise.
16319 * window.c (struct save_window_data, struct saved_window): Likewise.
16320 * window.h (struct window): Likewise.
16321 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
16322 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
16323 * buffer.c (init_buffer_once): Likewise.
16324 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
16326 * process.c (Fformat_network_address): Use local var for size,
16329 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
16331 Make the Lisp reader and string-to-float more consistent (Bug#8525)
16332 * data.c (atof): Remove decl; no longer used or needed.
16333 (digit_to_number): Move to lread.c.
16334 (Fstring_to_number): Use new string_to_number function, to be
16335 consistent with how the Lisp reader treats infinities and NaNs.
16336 Do not assume that floating-point numbers represent EMACS_INT
16337 without losing information; this is not true on most 64-bit hosts.
16338 Avoid double-rounding errors, by insisting on integers when
16339 parsing non-base-10 numbers, as the documentation specifies.
16340 * lisp.h (string_to_number): New decl, replacing ...
16341 (isfloat_string): Remove.
16342 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
16343 (read1): Do not accept +. and -. as integers; this
16344 appears to have been a coding error. Similarly, do not accept
16345 strings like +-1e0 as floating point numbers. Do not report
16346 overflow for integer overflows unless the base is not 10 which
16347 means we have no simple and reliable way to continue.
16348 Break out the floating-point parsing into a new
16349 function string_to_number, so that Fstring_to_number parses
16350 floating point numbers consistently with the Lisp reader.
16351 (digit_to_number): Move here from data.c. Make it static inline.
16352 (E_CHAR, EXP_INT): Remove, replacing with ...
16353 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
16354 (string_to_number): New function, replacing isfloat_string.
16355 This function checks for valid syntax and produces the resulting
16356 Lisp float number too. Rework it so that string-to-number
16357 no longer mishandles examples like "1.0e+". Use strtoumax,
16358 so that overflow for non-base-10 numbers is reported only when
16359 there's no portable and simple way to convert to floating point.
16361 * textprop.c (set_text_properties_1): Rewrite for clarity,
16362 and to avoid GCC warning about integer overflow.
16364 * intervals.h (struct interval): Use EMACS_INT for members
16365 where EMACS_UINT might cause problems. See
16366 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
16367 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
16368 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
16370 (offset_intervals): Tell GCC not to worry about length overflow
16371 when negating a negative length.
16373 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
16374 (overrun_check_free): Likewise.
16376 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
16377 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
16380 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
16381 (gnutls_make_error): Rename local to avoid shadowing.
16382 (gnutls_emacs_global_deinit): ifdef out; not used.
16383 (Fgnutls_boot): Use const for pointer to readonly storage.
16384 Comment out unused local. Fix pointer signedness problems.
16386 * lread.c (openp): Don't stuff size_t into an 'int'.
16387 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
16388 about possible signed overflow.
16390 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
16391 (GDK_KEY_g): Don't define if already defined.
16392 (xg_prepare_tooltip): Avoid pointer signedness problem.
16393 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
16395 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
16396 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
16398 * xfns.c (Fx_window_property): Simplify a bit,
16399 to make a bit faster and to avoid GCC 4.6.0 warning.
16400 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
16402 * fns.c (internal_equal): Don't assume size_t fits in int.
16404 * alloc.c (compact_small_strings): Tighten assertion a little.
16406 Replace pEd with more-general pI, and fix some printf arg casts.
16407 * lisp.h (pI): New macro, generalizing old pEd macro to other
16408 conversion specifiers. For example, use "...%"pI"d..." rather
16409 than "...%"pEd"...".
16410 (pEd): Remove. All uses replaced with similar uses of pI.
16411 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
16412 * alloc.c (check_pure_size): Don't overflow by converting size to int.
16413 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
16414 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
16415 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
16416 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
16417 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
16419 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
16420 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
16421 * print.c (safe_debug_print, print_object): Likewise.
16422 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
16424 Use pI instead of if-then-else-abort. Use %p to avoid casts,
16425 avoiding the 0 flag, which is not portable.
16426 * process.c (Fmake_network_process): Use pI to avoid cast.
16427 * region-cache.c (pp_cache): Likewise.
16428 * xdisp.c (decode_mode_spec): Likewise.
16429 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
16430 behavior on 64-bit hosts with printf arg.
16431 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
16432 (x_stop_queuing_selection_requests): Likewise.
16433 (x_get_window_property): Don't truncate byte count to an 'int'
16436 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
16437 here, since it parses constructs like leading '-' and spaces,
16438 which are not wanted; and it overflows with large numbers.
16439 Instead, simply match F[0-9]+, which is what is wanted anyway.
16441 * alloc.c: Remove unportable assumptions about struct layout.
16442 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
16443 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
16444 (allocate_vectorlike, make_pure_vector): Use the new macros,
16445 plus offsetof, to remove unportable assumptions about struct layout.
16446 These assumptions hold on all porting targets that I know of, but
16447 they are not guaranteed, they're easy to remove, and removing them
16448 makes further changes easier.
16450 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
16451 This doesn't fix a bug but makes the code clearer.
16452 (string_overrun_cookie): Now const. Use initializers that
16453 don't formally overflow signed char, to avoid warnings.
16454 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
16455 can cause Emacs to crash when string overrun checking is enabled.
16456 (allocate_buffer): Don't assume sizeof (struct buffer) is a

17351 * syntax.c (skip_chars): Likewise.
17353 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
17354 This also lets GCC 4.6.0 generate slightly better loop code.
17356 * callint.c (Fcall_interactively): <, not <=, for optimization.
17357 (Fcall_interactively): Count the number of arguments produced,
17358 not the number of arguments given. This is simpler and lets GCC
17359 4.6.0 generate slightly better code.
17361 * ftfont.c: Distingish more carefully between FcChar8 and char.
17362 The previous code passed unsigned char * to a functions like
17363 strlen and xstrcasecmp that expect char *, which does not
17364 conform to the C standard.
17365 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
17366 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
17367 char * when the C standard requires it.
17369 * keyboard.c (read_char): Remove unused var.
17371 * eval.c: Port to Windows vsnprintf (Bug#8435).
17372 Include <limits.h>.
17373 (SIZE_MAX): Define if the headers do not.
17374 (verror): Do not give up if vsnprintf returns a negative count.
17375 Instead, grow the buffer. This ports to Windows vsnprintf, which
17376 does not conform to C99. Problem reported by Eli Zaretskii.
17377 Also, simplify the allocation scheme, by avoiding the need for
17378 calling realloc, and removing the ALLOCATED variable.
17380 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
17382 Remove invocations of doprnt, as Emacs now uses vsnprintf.
17383 But keep the doprint source code for now, as we might revamp it
17384 and use it again (Bug#8435).
17385 * lisp.h (doprnt): Remove.
17386 * Makefile.in (base_obj): Remove doprnt.o.
17387 * deps.mk (doprnt.o): Remove.
17389 error: Print 32- and 64-bit integers portably (Bug#8435).
17390 Without this change, on typical 64-bit hosts error ("...%d...", N)
17391 was used to print both 32- and 64-bit integers N, which relied on
17392 undefined behavior.
17393 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
17394 * lisp.h (error, verror): Mark as printf-like functions.
17395 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
17396 Report overflow in size calculations when allocating printf buffer.
17397 Do not truncate output string at its first null byte.
17398 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
17399 Truncate the output at a character boundary, since vsnprintf does not
17401 * charset.c (check_iso_charset_parameter): Convert internal
17402 character to string before calling 'error', since %c now has the
17404 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
17405 overflow when computing char to be passed to 'error'. Do not
17406 pass Lisp_Object to 'error'; pass the integer instead.
17407 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
17408 formatted with plain %d.
17410 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
17412 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
17414 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
17416 * xterm.c (x_catch_errors): Remove duplicate declaration.
17418 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
17420 * xdisp.c, lisp.h (message_nolog): Remove; unused.
17422 2011-04-10 Jim Meyering <meyering@redhat.com>
17424 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
17425 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
17426 return ssize_t not "int", and use size_t as the buffer length.
17427 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
17428 * gnutls.h: Update declarations.
17429 * process.c (read_process_output): Use ssize_t, to match.
17430 (send_process): Likewise.
17432 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
17434 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
17436 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
17438 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
17439 Use unsigned char, to match FcChar8 type definition.
17441 * xterm.c (handle_one_xevent):
17442 * xmenu.c (create_and_show_popup_menu):
17443 * xselect.c (x_decline_selection_request)
17444 (x_reply_selection_request): Avoid type-punned deref of X events.
17446 2011-04-09 Eli Zaretskii <eliz@gnu.org>
17448 Fix some uses of `int' instead of EMACS_INT.
17449 * search.c (string_match_1, fast_string_match)
17450 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
17451 (scan_buffer, find_next_newline_no_quit)
17452 (find_before_next_newline, search_command, Freplace_match)
17453 (Fmatch_data): Make some `int' variables be EMACS_INT.
17455 * xdisp.c (display_count_lines): 3rd argument and return value now
17456 EMACS_INT. All callers changed.
17457 (pint2hrstr): Last argument is now EMACS_INT.
17459 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
17460 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
17461 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
17462 (decode_coding_utf_16, decode_coding_emacs_mule)
17463 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
17464 (decode_coding_ccl, decode_coding_charset)
17465 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
17466 (decode_coding_iso_2022, decode_coding_emacs_mule)
17467 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
17468 <char_offset, last_offset>: Declare EMACS_INT.
17469 (encode_coding_utf_8, encode_coding_utf_16)
17470 (encode_coding_emacs_mule, encode_invocation_designation)
17471 (encode_designation_at_bol, encode_coding_iso_2022)
17472 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
17473 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
17475 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
17476 (encode_invocation_designation): Last argument P_NCHARS is now
17478 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
17479 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
17481 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
17484 * ccl.c (Fccl_execute_on_string): Declare some variables
17487 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
17489 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
17491 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
17493 * process.c (Fformat_network_address): Doc fix.
17495 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
17497 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
17499 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
17501 * keyboard.c (read_char): Call Lisp function help-form-show,
17502 instead of using internal_with_output_to_temp_buffer.
17503 (Qhelp_form_show): New var.
17504 (syms_of_keyboard): Use DEFSYM macro.
17506 * print.c (internal_with_output_to_temp_buffer): Function deleted.
17508 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
17510 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
17512 * process.c (Flist_processes): Remove to Lisp.
17513 (list_processes_1): Delete.
17515 2011-04-06 Eli Zaretskii <eliz@gnu.org>
17517 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
17519 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
17521 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
17523 Fix more problems found by GCC 4.6.0's static checks.
17525 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
17527 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
17529 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
17531 * xdisp.c (vmessage): Mark as a printf-like function.
17533 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
17535 * sound.c (sound_warning): Don't crash if arg contains a printf format.
17537 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
17538 printf-like functions.
17539 (tiff_load): Add casts to remove these marks before passing them
17540 to system-supplied API.
17542 * eval.c (Fsignal): Remove excess argument to 'fatal'.
17544 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
17545 This avoids several warnings with gcc -Wstrict-overflow.
17546 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
17547 directly, rather than having caller test rule sign. This avoids
17548 some unnecessary tests.
17549 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
17550 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
17551 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
17553 * xfont.c (xfont_text_extents): Remove var that was set but not used.
17554 (xfont_open): Avoid unnecessary tests.
17556 * composite.c (composition_gstring_put_cache): Use unsigned integer.
17558 * composite.h, composite.c (composition_gstring_put_cache):
17559 Use EMACS_INT, not int, for length.
17561 * composite.h (COMPOSITION_DECODE_REFS): New macro,
17562 breaking out part of COMPOSITION_DECODE_RULE.
17563 (COMPOSITION_DECODE_RULE): Use it.
17564 * composite.c (get_composition_id): Remove unused local vars,
17565 by using the new macro.
17567 * textprop.c (set_text_properties_1): Change while to do-while,
17568 since the condition is always true at first.
17570 * intervals.c (graft_intervals_into_buffer): Mark var as used.
17571 (interval_deletion_adjustment): Return unsigned value.
17574 * process.c (list_processes_1, create_pty, read_process_output):
17575 (exec_sentinel): Remove vars that were set but not used.
17576 (create_pty): Remove unnecessary "volatile"s.
17577 (Fnetwork_interface_info): Avoid possibility of int overflow.

17579 (read_process_output): Simplify nbytes computation if buffered.
17581 * bytecode.c (exec_byte_code): Rename local to avoid shadowing.
17583 * syntax.c (scan_words): Remove var that was set but not used.
17584 (update_syntax_table): Use unsigned instead of int.
17586 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
17587 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
17588 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
17590 * print.c (print_error_message): Avoid int overflow.
17592 * font.c (font_list_entities): Redo for clarity,
17593 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
17595 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
17596 (font_score): Avoid potential overflow in diff calculation.
17598 * fns.c (substring_both): Remove var that is set but not used.
17599 (sxhash): Redo loop for clarity and to avoid wraparound warning.
17601 * eval.c (funcall_lambda): Rename local to avoid shadowing.
17603 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
17604 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
17605 can always succeed if overflow has undefined behavior.
17607 * search.c (boyer_moore, wordify): Remove vars set but not used.
17608 (wordify): Omit three unnecessary tests.
17610 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
17611 All callers changed. This avoids the need for an unused var.
17613 * casefiddle.c (casify_region): Remove var that is set but not used.
17615 * dired.c (file_name_completion): Remove var that is set but not used.
17617 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
17619 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
17620 (Finsert_file_contents): Remove unnecessary code checking fd.
17622 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
17623 Check for integer overflow on size calculations.
17625 * buffer.c (Fprevious_overlay_change): Remove var that is set
17628 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
17629 Remove vars that are set but not used.
17630 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
17631 (timer_check_2): Mark vars as initialized.
17633 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
17635 * image.c (lookup_image): Remove var that is set but not used.
17636 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
17638 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
17639 that are set but not used.
17641 * xfns.c (make_invisible_cursor): Don't return garbage
17642 if XCreateBitmapFromData fails (Bug#8410).
17644 * xselect.c (x_get_local_selection, x_handle_property_notify):
17645 Remove vars that are set but not used.
17647 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
17648 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
17650 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
17651 Remove var that is set but not used.
17652 (scroll_bar_windows_size): Now size_t, not int.
17653 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
17654 Check for overflow.
17656 * xfaces.c (realize_named_face): Remove vars that are set but not used.
17657 (map_tty_color) [!defined MSDOS]: Likewise.
17659 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
17661 * coding.c: Remove vars that are set but not used.
17662 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
17663 All callers changed.
17664 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
17665 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
17666 (decode_coding_charset): Remove vars that are set but not used.
17668 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
17669 that is set but not used.
17671 * print.c (print_object): Remove var that is set but not used.
17673 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
17674 The gnulib version avoids calling malloc in the usual case,
17675 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
17676 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
17677 * filelock.c (current_lock_owner): Likewise.
17678 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
17679 * sysdep.c: Include allocator.h, careadlinkat.h.
17680 (emacs_no_realloc_allocator): New static constant.
17681 (emacs_readlink): New function.
17682 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
17683 ../lib/careadlinkat.h.
17685 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
17687 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
17688 first non-nil return value).
17690 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
17692 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
17693 if not defined (Bug#8403).
17695 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
17697 * xdisp.c (display_count_lines): Remove parameter `start',
17698 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
17699 (get_char_face_and_encoding): Remove parameter `multibyte_p',
17700 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
17701 (fill_stretch_glyph_string): Remove parameters `row' and `area',
17702 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
17703 and thereabouts. All callers changed.
17704 (get_per_char_metric): Remove parameter `f', unused since
17705 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
17707 2011-04-02 Jim Meyering <meyering@redhat.com>
17709 do not dereference NULL upon failed strdup
17710 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
17711 (ns_get_family): Likewise.
17713 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
17715 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
17717 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
17719 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
17722 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
17724 Add lexical binding.
17726 * window.c (Ftemp_output_buffer_show): New fun.
17727 (Fsave_window_excursion):
17728 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
17730 * lread.c (lisp_file_lexically_bound_p): New function.
17731 (Fload): Bind Qlexical_binding.
17732 (readevalloop): Remove `evalfun' arg.
17733 Bind Qinternal_interpreter_environment.
17734 (Feval_buffer): Bind Qlexical_binding.
17735 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
17737 (syms_of_lread): Declare `lexical-binding'.
17739 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
17741 * keyboard.c (eval_dyn): New fun.
17742 (menu_item_eval_property): Use it.
17744 * image.c (parse_image_spec): Use Ffunctionp.
17746 * fns.c (concat, mapcar1): Accept byte-code-functions.
17748 * eval.c (Fsetq): Handle lexical vars.
17749 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
17750 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
17751 (FletX, Flet): Obey lexical binding.
17752 (Fcommandp): Handle closures.
17753 (Feval): New `lexical' arg.
17754 (eval_sub): New function extracted from Feval. Use it almost
17755 everywhere where Feval was used. Look up vars in lexical env.
17757 (Ffunctionp): Move from subr.el.
17758 (Ffuncall): Handle closures.
17759 (apply_lambda): Remove `eval_flags'.
17760 (funcall_lambda): Handle closures and new byte-code-functions.
17761 (Fspecial_variable_p): New function.
17762 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
17763 but without exporting it to Lisp.
17765 * doc.c (Fdocumentation, store_function_docstring):
17766 * data.c (Finteractive_form): Handle closures.
17768 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
17771 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
17773 (exec_byte_code): New function extracted from Fbyte_code to handle new
17774 calling convention for byte-code-functions. Add new byte-codes.
17776 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
17778 * alloc.c (Fmake_symbol): Init new `declared_special' field.
17780 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
17782 * xdisp.c (redisplay_internal): Fix prototype.
17784 2011-03-31 Eli Zaretskii <eliz@gnu.org>
17786 * xdisp.c (SCROLL_LIMIT): New macro.
17787 (try_scrolling): Use it when setting scroll_limit.
17788 Limit scrolling to 100 screen lines.
17789 (redisplay_window): Even when falling back on "recentering",
17790 position point in the window according to scroll-conservatively,
17791 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
17793 (try_scrolling): When point is above the window, allow searching
17794 as far as scroll_max, or one screenful, to compute vertical
17795 distance from PT to the scroll margin position. This prevents
17796 try_scrolling from unnecessarily failing when
17797 scroll-conservatively is set to a value slightly larger than the
17798 window height. Clean up the case of PT below the margin at bottom
17799 of window: scroll_max can no longer be INT_MAX. When aggressive
17800 scrolling is in use, don't let point enter the opposite scroll
17801 margin as result of the scroll.
17802 (syms_of_xdisp) <scroll-conservatively>: Document the
17803 threshold of 100 lines for never-recentering scrolling.
17805 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
17807 * dispextern.h (move_it_by_lines):
17808 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
17809 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
17810 (message_log_check_duplicate): Remove parameters `prev_bol' and
17811 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
17812 (redisplay_internal): Remove parameter `preserve_echo_area',
17813 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
17815 * indent.c (Fvertical_motion):
17816 * window.c (window_scroll_pixel_based, Frecenter):
17817 Don't pass `need_y_p' to `move_it_by_lines'.
17819 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
17821 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
17822 steal a few bits to be more compact.
17823 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
17824 Remove unneeded casts.
17826 * bytecode.c (Fbyte_code): CAR and CDR can GC.
17828 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
17830 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
17831 binding" message (bug#7967).
17833 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
17835 Fix more problems found by GCC 4.6.0's static checks.
17837 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
17838 Remove unused local var.
17840 * editfns.c (Fmessage_box): Remove unused local var.
17842 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
17843 (note_mode_line_or_margin_highlight, note_mouse_highlight):
17844 Omit unused local vars.
17845 * window.c (shrink_windows): Omit unused local var.
17846 * menu.c (digest_single_submenu): Omit unused local var.
17847 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
17848 Omit unused local var.
17850 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
17851 Don't assume string length fits in int.
17852 (keyremap_step, read_key_sequence): Use size_t for sizes.
17853 (read_key_sequence): Don't check last_real_key_start redundantly.
17855 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
17856 instead of alloca (Bug#8344).
17858 * eval.c (Fbacktrace): Don't assume nargs fits in int.
17859 (Fbacktrace_frame): Don't assume nframes fits in int.
17861 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
17863 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
17866 * term.c (produce_glyphless_glyph): Remove unnecessary test.
17868 * cm.c (calccost): Turn while-do into do-while, for clarity.
17870 * keyboard.c (syms_of_keyboard): Use the same style as later
17871 in this function when indexing through an array. This also
17872 works around GCC bug 48267.
17874 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
17876 * xselect.c (x_check_property_data): Return correct size (Bug#8335).

17879 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
17881 * keyboard.c, keyboard.h (num_input_events): Now size_t.
17882 This avoids undefined behavior on integer overflow, and is a bit
17883 more convenient anyway since it is compared to a size_t variable.
17885 Variadic C functions now count arguments with size_t, not int.
17886 This avoids an unnecessary limitation on 64-bit machines, which
17887 caused (substring ...) to crash on large vectors (Bug#8344).
17888 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
17889 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

17895 (internal_condition_case_n, run_hook_with_args, apply_lambda)
17896 (funcall_lambda, mark_backtrace): Likewise.
17897 * fns.c (concat): Likewise.
17898 * frame.c (x_set_frame_parameters): Likewise.
17899 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
17900 0 if not found, not -1. All callers changed.
17902 * alloc.c (garbage_collect): Don't assume stack size fits in int.
17903 (stack_copy_size): Now size_t, not int.
17904 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
17906 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
17908 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
17909 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
17910 All callers changed.
17912 * lisp.h (multibyte_char_to_unibyte):
17913 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
17914 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

17916 * cmds.c (internal_self_insert):
17917 * editfns.c (general_insert_function):
17918 * keymap.c (push_key_description):
17919 * search.c (Freplace_match):
17920 * xdisp.c (message_dolog, set_message_1): All callers changed.
17922 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
17924 * keyboard.c (safe_run_hook_funcall): New function.
17925 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
17926 don't set the hook to nil, but remove the offending function instead.
17927 (Qcommand_hook_internal): Remove, unused.
17928 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
17929 Vcommand_hook_internal.
17931 * eval.c (enum run_hooks_condition): Remove.
17932 (funcall_nil, funcall_not): New functions.
17933 (run_hook_with_args): Call each function through a `funcall' argument.
17934 Remove `cond' argument, now redundant.
17935 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
17936 (Frun_hook_with_args_until_failure): Adjust accordingly.
17937 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
17939 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
17941 * dispextern.h (string_buffer_position): Remove declaration.
17943 * print.c (strout): Remove parameter `multibyte', unused since
17944 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
17946 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
17947 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
17948 All callers changed.
17950 * w32.c (_wsa_errlist): Use braces for struct initializers.
17952 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
17953 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
17954 All callers changed.
17955 (string_buffer_position): Likewise. Also, make static (it's never
17956 used outside xdisp.c).
17957 (cursor_row_p): Remove parameter `w', unused since
17958 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.

17960 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
17961 All callers changed.
17963 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
17965 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.

17976 (syms_of_nsterm): DEFVAR ns-auto-hide-menu-bar, init to Qnil.
17978 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>

17991 2011-03-26 Eli Zaretskii <eliz@gnu.org>
17993 * xdisp.c (redisplay_window): Don't check buffer's clip_changed
17994 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
17996 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
17998 * w32.c (read_unc_volume): Use parameter `henum', instead of
17999 global variable `wget_enum_handle'.
18001 * keymap.c (describe_vector): Remove parameters `indices' and
18002 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.

18013 * w32menu.c (w32_menu_display_help):
18014 * xmenu.c (show_help_event, menu_help_callback):
18015 Adjust calls to `show_help_echo'.
18017 * gtkutil.c (xg_maybe_add_timer):
18018 * keyboard.c (readable_events):
18019 * process.c (wait_reading_process_output):
18020 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
18022 * insdel.c (adjust_markers_gap_motion):
18023 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.

18097 2011-03-23 Julien Danjou <julien@danjou.info>
18099 * term.c (Fsuspend_tty, Fresume_tty):
18100 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
18101 * window.c (temp_output_buffer_show):
18102 * insdel.c (signal_before_change):
18103 * frame.c (Fhandle_switch_frame):

18106 * editfns.c (save_excursion_restore):
18107 * cmds.c (internal_self_insert):
18108 * callint.c (Fcall_interactively):
18109 * buffer.c (Fkill_all_local_variables):
18110 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
18112 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
18113 unconditionally since it does the check itself.
18115 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
18117 Fix more problems found by GCC 4.5.2's static checks.
18119 * coding.c (encode_coding_raw_text): Avoid unnecessary test
18120 the first time through the loop, since we know p0 < p1 then.
18121 This also avoids a gcc -Wstrict-overflow warning.
18123 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
18124 leading to a memory leak, possible in functions like
18125 load_charset_map_from_file that can allocate an unbounded number
18126 of objects (Bug#8318).
18128 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
18129 that could (at least in theory) be that large.
18131 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
18132 This is less likely to overflow, and avoids undefined behavior if
18133 overflow does occur. All callers changed. Use strtoul to scan
18134 for the unsigned long integer.
18135 (pint2hrstr): Simplify and tune code slightly.
18136 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

18144 This also avoids a warning with gcc -Wstrict-overflow.
18146 * fileio.c (Fcopy_file): Report error if fchown or fchmod
18149 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
18151 * process.c (Fmake_network_process): Use socklen_t, not int,
18152 where POSIX says socklen_t is required in portable programs.
18153 This fixes a porting bug on hosts like 64-bit HP-UX, where
18154 socklen_t is wider than int (Bug#8277).
18155 (Fmake_network_process, server_accept_connection):
18156 (wait_reading_process_output, read_process_output):
18159 * process.c: Rename or move locals to avoid shadowing.
18160 (list_processes_1, Fmake_network_process):
18161 (read_process_output_error_handler, exec_sentinel_error_handler):
18162 Rename or move locals.
18163 (Fmake_network_process): Define label "retry_connect" only if needed.
18164 (Fnetwork_interface_info): Fix pointer signedness.
18165 (process_send_signal): Add cast to avoid pointer signedness problem.
18166 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
18167 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
18169 Make tparam.h and terminfo.c consistent.
18170 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
18171 Include tparam.h instead, since it declares them.
18172 * cm.h (PC): Remove extern decl; tparam.h now does this.
18173 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
18174 * terminfo.c: Include tparam.h, to check interfaces.
18175 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
18176 (tparam): Adjust signature to match interface in tparam.h;
18177 this removes some undefined behavior. Check that outstring and len
18178 are zero, which they always are with Emacs.
18179 * tparam.h (PC, BC, UP): New extern decls.
18181 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
18182 (xftfont_open): Rename locals to avoid shadowing.
18184 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
18185 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
18186 (OTF_TAG_SYM): Omit macro if not needed.
18187 (ftfont_list): Remove unused local.
18188 (get_adstyle_property, ftfont_pattern_entity):
18189 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
18190 Rename locals to avoid shadowing.
18192 * xfont.c (xfont_list_family): Mark var as initialized.
18194 * xml.c (make_dom): Now static.
18196 * composite.c (composition_compute_stop_pos): Rename local to
18198 (composition_reseat_it): Remove unused locals.
18199 (find_automatic_composition, composition_adjust_point): Likewise.
18200 (composition_update_it): Mark var as initialized.
18201 (find_automatic_composition): Mark vars as initialized,
18202 with a FIXME (Bug#8290).
18204 character.h: Rename locals to avoid shadowing.
18205 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
18206 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
18207 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
18208 (BUF_DEC_POS): Be more systematic about renaming local temporaries
18209 to avoid shadowing.
18211 * textprop.c (property_change_between_p): Remove; unused.
18213 * intervals.c (interval_start_pos): Now static.
18215 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".
18217 * atimer.c (start_atimer, append_atimer_lists, set_alarm):
18218 Rename locals to avoid shadowing.
18220 * sound.c (wav_play, au_play, Fplay_sound_internal):
18221 Fix pointer signedness.
18222 (alsa_choose_format): Remove unused local var.
18223 (wav_play): Initialize a variable to 0, to prevent undefined
18224 behavior (Bug#8278).
18226 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
18228 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
18230 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
18231 clobbering (Bug#8298).
18232 * sysdep.c (sys_subshell): Likewise.
18233 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
18235 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
18236 This should get cleaned up, so that child_setup has the
18237 same signature on all platforms.
18239 * callproc.c (call_process_cleanup): Now static.
18240 (relocate_fd): Rename locals to avoid shadowing.
18242 2011-03-22 Chong Yidong <cyd@stupidchicken.com>

18409 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
18410 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
18411 to use the following functions instead of these macros.
18412 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
18413 EMACS_INT, since callers assume the returned value fits in int.
18414 (upcase1): Likewise, for UPCASE_TABLE.
18415 (uppercasep, lowercasep, upcase): New static inline functions.
18416 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

18426 (regex_compile, re_match_2_internal): Mark locals as initialized.
18427 (RETALLOC_IF): Define only if needed.
18428 (WORDCHAR_P): Likewise. This one is never needed, but is used
18429 only in a comment talking about a compiler bug, so put inside
18430 the #if 0 of that comment.
18431 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
18432 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

18458 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
18459 New macros, so that the caller can use some names other than
18460 gcpro1, gcpro2, etc.
18461 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
18463 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
18464 argument, for consistency with GCPRO2_VAR, etc: it is now the
18465 prefix of the variable, not the variable itself. All uses
18467 * dired.c (directory_files_internal, file_name_completion):
18468 Rename locals to avoid shadowing.
18470 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
18471 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
18472 dired.c's scmp function, had undefined behavior.
18473 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
18474 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
18475 * buffer.h: ... to here, because these macros use current_buffer,
18476 and the new implementation with inline functions needs to have
18477 current_buffer in scope now, rather than later when the macros
18479 (downcase, upcase1): New static inline functions.
18480 (DOWNCASE, UPCASE1): Reimplement using these functions.
18481 This avoids undefined behavior in expressions like
18482 DOWNCASE (x) == DOWNCASE (y), which previously suffered
18483 from race conditions in accessing the global variables
18484 case_temp1 and case_temp2.
18485 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
18486 * lisp.h (case_temp1, case_temp2): Remove their decls.
18487 * character.h (ASCII_CHAR_P): Move from here ...
18488 * lisp.h: ... to here, so that the inline functions mentioned
18489 above can use them.
18491 * dired.c (directory_files_internal_unwind): Now static.
18493 * fileio.c (file_name_as_directory, directory_file_name):

18496 (file_name_as_directory): Use const pointers when appropriate.
18497 (Fexpand_file_name): Likewise. In particular, newdir might
18498 point at constant storage, so make it a const pointer.
18499 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
18500 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
18502 (Fset_file_times, Finsert_file_contents, auto_save_error):

18507 to avoid shadowing.
18509 * marker.c (bytepos_to_charpos): Remove; unused.
18511 * lisp.h (verify_bytepos, count_markers): New decls,
18512 so that gcc does not warn that these functions aren't declared.
18514 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
18515 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
18516 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
18517 (copy_text): Remove unused local var.
18519 * filelock.c (within_one_second): Now static.
18520 (lock_file_1): Rename local to avoid shadowing.
18522 * buffer.c (fix_overlays_before): Mark locals as initialized.
18523 (fix_start_end_in_overlays): Likewise. This function should be
18524 simplified by using pointers-to-pointers, but that's a different
18526 (switch_to_buffer_1): Now static.
18527 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
18528 (report_overlay_modification): Rename locals to avoid shadowing.
18530 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
18531 Fix pointer signedness issue.
18532 (sys_subshell): Mark local as volatile if checking for lint,
18533 to suppress a gcc -Wclobbered warning that does not seem to be right.
18534 (MAXPATHLEN): Define only if needed.
18536 * process.c (serial_open, serial_configure): Move decls from here ...
18537 * systty.h: ... to here, so that they can be checked.
18539 * fns.c (get_random, seed_random): Move extern decls from here ...
18540 * lisp.h: ... to here, so that they can be checked.
18542 * sysdep.c (reset_io): Now static.
18543 (wait_for_termination_signal): Remove; unused.
18545 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):

18548 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
18549 (DENSE_TABLE_SIZE): Remove; unused.
18550 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
18551 (describe_map_tree):
18552 Rename locals to avoid shadowing.
18554 * keyboard.c: Declare functions static if they are not used elsewhere.

18701 For example, without this patch (encode-time 0 0 0 1 1
18702 1152921504606846976) returns the obviously-bogus value (-948597
18703 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
