3 Fix some stat-related races.
4 * fileio.c (Fwrite_region): Avoid race condition if a file is
5 removed or renamed by some other process immediately after Emacs
6 writes it but before Emacs stats it. Do not assume that stat (or
8 * image.c (slurp_file): Resolve the file name with fopen + fstat
9 rather than stat + fopen.
10 (pbm_read_file) [0]: Remove unused code with stat race.

12 Remove ineffective code with stat race.
14 2012-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
16 * doc.c (get_doc_string): Don't signal an error if the file is missing.

40 a file exists. This avoids expensive system calls on MS-Windows.
43 * w32.c (init_environment): Call 'check_existing' instead of

135 * keyboard.c (timers_run, swallow_events)
136 (detect_input_pending_run_timers):
137 * process.c (wait_reading_process_output):
138 Use unsigned for counter where wraparound-on-overflow is desired,
139 since unsigned is guaranteed to have that behavior and signed is not.
140 (read_char): Use ptrdiff_t for string length.
141 (get_input_pending): Remove first argument, since it was always
142 the same pointer-to-int (now pointer-to-boolean) &input_pending,
143 and behave as if it had that value. Return new value of
144 input_pending. All callers changed.
145 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
146 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's

166 Clean out old termopts cruft.
167 * termopts.h (flow_control, meta_key): Remove unused decls.
168 * dispnew.c, indent.c, nsterm.m, term.c, xsettings.c, xsmfns.c:
169 Don't include termopts.h.
171 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>
173 * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers.
175 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>

186 2012-10-09 Eli Zaretskii <eliz@gnu.org>
188 * w32fns.c (w32_last_error): Change the return value to DWORD, to
189 match what GetLastError returns. Explain why the function is
192 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
193 'is_tooltip_frame', to avoid confusion with its global namesake.
195 2012-10-08 Daniel Colascione <dancol@dancol.org>
197 * xdisp.c (start_hourglass): Call w32_note_current_window when
198 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
199 build that caused Emacs to display the hourglass cursor forever.
201 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
202 which is broken under remote desktop, calculate the number of
203 colors available for a display based on the display's number of
204 planes and number of bits per pixel per plane. (bug#10397).
206 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
208 * nsfont.m (Vfonts_in_cache): New variable.
209 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
210 are used. Add cached fonts to Vfonts_in_cache.
211 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
213 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
215 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
217 (FONT_H): Define after FRAME_H.
218 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
221 * w32term.c: Remove leftover declaration of keyboard_codepage.
223 2012-10-08 Eli Zaretskii <eliz@gnu.org>

227 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
228 (GLOBAL_SOURCES): Add cygw32.c.
229 ($(BLD)/unexw32.$(O)):
231 ($(BLD)/w32console.$(O)):

243 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
244 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
245 accidental message numbering hole. Change other messages to
248 * w32select.h (HAVE_W32SELECT): Remove.
250 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
251 w32common.h instead of w32heap.h
253 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)

261 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
262 (w32_minor_version, w32_build_number, w32_subtype): Remove
263 duplicate definitions.
265 * w32fns.c: Include w32common.h; include w32heap.h only in
268 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
269 Use `report_file_error' instead of `error' in order to better
270 inform users of what went wrong. Increase NTGUI_UNICODE file
271 dialog box file name length to 32k, the maximum allowed by the NT
274 * w32common.h: New file.
275 (ROUND_UP, ROUND_DOWN, get_page_size)
276 (get_allocation_unit, get_processor_type, get_w32_major_version)
277 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
278 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
279 (OS_NT, os_subtype, cache_system_info): Move here.
281 * unexw32.c, unexcw.c: Include w32common.h.
283 * emacs.c (main): Use (defined (WINDOWSNT) || defined
284 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
285 to call syms_of_w32select.
287 * cygw32.h: Remove obsolete EXFUN declarations.
289 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
291 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
292 of w32inevt.o from SOME_MACHINE_OBJECTS.
294 2012-10-08 Daniel Colascione <dancol@dancol.org>
296 * image.c: Permanent fix for JPEG compilation issue --- limit
297 jpeglib `boolean' redefinition to Cygwin builds.
299 2012-10-08 Eli Zaretskii <eliz@gnu.org>
301 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
303 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
306 2012-10-08 Daniel Colascione <dancol@dancol.org>
308 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
309 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
310 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
311 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
312 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
313 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
314 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
315 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
316 now a supported configuration.
318 * Makefile.in: consolidate image variables into LIBIMAGE; add
319 W32_OBJ and W32_LIBS. Compile new files.
322 (_DebPrint) declare tracing facility for W32 debugging. We need
323 to unify tracing later.
325 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
326 unconditional use of W32 Unicode functions. Cygwin runs only on
327 100% Unicode operating systems.
329 * cygw32.c: New file. Define Cygwin-specific facilities.
330 (Fcygwin_convert_path_to_windows)
331 (Fcygwin_convert_path_from_windows): New user functions for
332 accessing Cygwin path-munging routines.
334 * cygw32.h: New file.
335 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
336 UTF-16LE strings temporarily inside non-Lisp-visible string
339 (w32_strerror): Just what it says on the tin.
341 * emacs.c: Make the NS fork-then-exec code for daemon-launching
342 also run for Cygwin; both systems have the same problem with using
343 GUI facilities in a forked child. Also call syms_of_cygw32,
344 syms_of_w32select in correct places.
346 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
347 needs fork-then-exec for daemon launching.
349 * font.h: Include frame.h.
351 * image.c: Use the image library cache machinery only when we're
352 compiling for native WINDOWSNT; Cygwin can use shared libraries
353 like any other Unixlike system.
355 * keyboard.c: Clarify a comment regarding the input loop.
357 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
358 functions directly instead of trying to detect at runtime that our
359 host operating system supports them. We make this change for two
360 reasons: Cygwin lacks support for the multibyte character
361 conversion functions used by the legacy menu code, and Cygwin
362 never needs to rely on non-Unicode APIs.
364 * unexw32.c (hinst): Declare extern.
366 * w32.c: Change header order;
367 (w32_strerror): Move to w32fns.c because we need it for
368 non-WINDOWSNT builds.
370 * w32.h: Add #error macro to make sure we don't include w32.h for
371 Cygwin builds. Remove w32select declarations.
373 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
374 w32fns.c. w32console.c is WINDOWSNT-only.
376 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
377 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
379 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
380 (w32_major_version, w32_minor_version, w32_build_number)
381 (os_subtype, sound_type): Define here
382 (w32_defined_color): Make color parameter const for consistency
383 with other _defined_color functions.
384 (w32_createwindow): Unconditionally call w32_init_class instead of
385 doing so only when hprevinst is non-NULL. Plumbing hprevinst
386 through the code is complex and unnecessary because class
387 registration is practically free.
388 (w32_name_of_message): New EMACSDEBUG-only function.
389 (Fset_message_beep): Move here
390 (Fx_open_connection): Require that the display name for Windows be
391 "w32" for consistency, emacsclient disambiguation, and maybe, one
392 day, multi-window-system support.
393 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
394 Cygwin files for W32 GUI facilities, since these clearly don't
397 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
398 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
399 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
400 (w32_last_error): Remove.
402 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
404 * w32heap.c (syspage_mask): Declare here.
405 (cache_system_info): Remove.
407 * w32inevt.c (faked_key): Define globally, not statically.
408 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
409 (w32_console_toggle_lock_key): Move to w32fns.c.
411 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
413 * w32proc.c (_DebPrint): Move to w32fns.c.
414 * w32select.c: Include string.h, stdio.h for Cygwin.
415 * w32select.h: New File.
417 * w32term.c: Include io.h for non-CYGWIN builds; needed for
419 (w32_message_fd): New variable. Under Cygwin, holds the file
420 descriptor the system used to tell us about pending thread
423 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
424 that prevented compilation under non-WINDOWSNT systems.
426 (w32_initialize): Open /dev/windows and assign it to
427 w32_message_fd. Provide w32 feature.
429 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
430 (WM_EMACS_INPUT_READY): add.
431 (prepend_msg, w32_message_fd): Declare globally.
434 (keyboard_handle): Use only when WINDOWSNT.
435 (notify_msg_ready): New function. Posts a message to the main
436 thread's message queue under CYGWIN, which wakes up the main
437 thread from select(2) by making the /dev/windows file descriptor
438 ready. Under WINDOWSNT, it sets an event the same way the old
441 (post, prepend_msg): Actually call notify_msg_ready instead of
442 setting the input event directly.
444 2012-10-07 Eli Zaretskii <eliz@gnu.org>
446 * ralloc.c (relinquish): If a heap is ready to be relinquished,
447 but it still has blocs in it, don't return it to the system,
448 instead of aborting. (Bug#12402)
450 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
452 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
454 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
455 MAC_OS_X_VERSION_10_6.
456 (syms_of_nsterm): Remove comment about Panther and above for

465 * nsmenu.m (fillWithWidgetValue:): Remove code for <
466 MAC_OS_X_VERSION_10_2.
468 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
470 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
471 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
473 * nsterm.m (ns_in_resize): Remove (Bug#12479).
474 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
475 (ns_clear_frame, sendEvent, windowDidResize, drawRect:): Remove
477 (ns_clear_frame_area): Remove resize handle code.
479 * nsfns.m (ns_in_resize): Remove.
480 (x_set_icon_name, ns_set_name, ns_set_name_as_filename): Remove
483 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
485 Improve sys_siglist detection.
486 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
487 defined as a macro, as is done in Solaris.
488 (sys_siglist_entries): New macro.
489 (save_strsignal): Use it.
490 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
491 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
493 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
495 * nsfns.m (Fx_create_frame): Call x_default_parameter with
496 fullscreen/Fullscreen.

514 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
516 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
518 2012-10-05 Eli Zaretskii <eliz@gnu.org>
520 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
522 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
523 that time stamps of directories could also be changed. Don't
524 request the too broad GENERIC_WRITE, only the more restrictive
525 FILE_WRITE_ATTRIBUTES access rights.
527 * fileio.c (Fset_file_times): Special-case ignoring errors for
528 directories only on MSDOS, not on MS-Windows.
530 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
532 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
534 2012-10-04 Eli Zaretskii <eliz@gnu.org>
536 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
537 see whether CreateFile failed.
539 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
541 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
542 to avoid similar races.
543 * keyboard.c (pending_signals): Now bool, not int.
545 Port timers to OpenBSD, plus check for timer failures.
546 OpenBSD problem reported by Han Boetes.
547 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
549 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
550 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
551 like OpenBSD, which has timer_settime but does not declare it.
552 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
553 whether to use itimerspec-related primitives. All uses of
554 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
556 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
558 * profiler.c (handle_profiler_signal): Fix a malloc race
559 that caused Emacs to hang on Fedora 17 when profiling Lisp.

568 consistent with the change in return value of 'safe_strsignal'.
570 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
572 Prefer plain 'static' to 'static inline' (Bug#12541).

580 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
581 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
582 Now 'static', not 'static inline'.
584 Count overruns when profiling; change units to ns.
585 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
586 Give extra weight to samples after overruns, to attempt to count
587 the time more accurately.
588 (setup_cpu_timer): Change sampling interval units from ms to ns, since
589 the underlying primitives nominally do ns.
590 (Fprofiler_cpu_start): Document the change. Mention that
591 the sampling intervals are only approximate.
593 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
595 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
597 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
598 case for the special 0 coding-system.
600 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
601 (Fmake_overlay): Remove redundant tests.
602 (fix_start_end_in_overlays): Remove redundant recentering.
604 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
606 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
609 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
611 Fix a malloc race condition involving strsignal.
612 A signal can arrive in the middle of a malloc, and Emacs's signal
613 handler can invoke strsignal, which can invoke malloc, which is
614 not portable. This race condition bug makes Emacs hang on GNU/Linux.
615 Fix it by altering the signal handler so that it does not invoke
617 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
618 * process.c (status_message): Use const pointer, in case strsignal
619 is #defined to safe_strsignal.
620 * sysdep.c (sys_siglist, init_signals): Always define and
621 initialize a substitute sys_siglist if the system does not define
622 one, even if HAVE_STRSIGNAL.
623 (safe_strsignal): Rename from strsignal. Always define,
624 using sys_siglist. Return a const pointer.
625 * syssignal.h (safe_strsignal): New decl.
626 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
628 2012-10-01 Eli Zaretskii <eliz@gnu.org>
630 * w32proc.c (timer_loop): Fix code that waits for timer
631 expiration, to avoid high CPU usage.
633 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
635 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
636 (sweep_weak_table): Remove redundant prototypes.
638 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
640 * emacs.c: Move the inclusion of TERM_HEADER after including
641 windows.h on WINDOWSNT. This avoids compilation problems with
644 2012-10-01 Eli Zaretskii <eliz@gnu.org>
646 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
647 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
648 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
649 as the previous version used 'void *'.
651 * ralloc.c (ROUNDUP): Fix last change.
652 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
655 * w32proc.c <disable_itimers>: New static flag.
656 (init_timers): Initialize it to zero, after creating the critical
657 sections used by the timer threads.
658 (term_timers): Set to 1 before deleting the critical sections.
659 (getitimer, setitimer): If disable_itimers is non-zero, return an
660 error indication without doing anything. Reported by Fabrice
661 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
662 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
664 [!HAVE_SETITIMER]: Behave as the previous version that didn't
667 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
668 term_ntproc after all the other bookkeeping, to get timers working
671 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
673 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
674 Suggested by Juri Linkov in
675 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
677 Prefer plain 'static' to 'static inline' (Bug#12541).
678 With static functions, modern compilers inline pretty well by
679 themselves; advice from programmers often hurts as much as it helps.
680 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
681 this change shrinks the text size of the Emacs executable by 1.1%
682 without affecting CPU significantly in my benchmark.

966 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
967 signal.h, setjmp.h. Include systime.h instead.
968 (saturated_add): New function.
969 (record_backtrace, current_sample_interval): Use EMACS_INT, not size_t.
970 (record_backtrace, handle_profiler_signal): Saturate on fixnum overflow.
971 (profiler_timer, profiler_timer_ok) [HAVE_TIMER_SETTIME]:
973 (enum profiler_cpu_running): New enum.
974 (profiler_cpu_running): Now of that enum type, not bool.
975 All uses changed to store the new value.
976 (handle_profiler_signal): Rename from sigprof_handler_1,
977 for consistency with other handlers. Do not check whether
978 cpu_log is a hash-table if garbage collecting, since it
979 doesn't matter in that case.
980 (deliver_profiler_signal): Rename from sigprof_handler,
981 for consistency with other handlers.
982 (setup_cpu_timer): New function, with much of what used to be in
983 Fprofiler_cpu_start. Check for out-of-range argument.
984 Prefer timer_settime if available, and prefer
985 thread cputime clocks, then process cputime clocks, then
986 monotonic clocks, to the old realtime clock. Use make_timeval
987 to round more-correctly when falling back to setitimer.
988 (Fprofiler_cpu_start): Use it.
989 (Fprofiler_cpu_stop): Prefer timer_settime if available.
990 Don't assume that passing NULL as the 2nd argument of setitimer
991 is the same as passing a pointer to all-zero storage.
992 Ignore SIGPROF afterwards.
993 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
994 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
995 non-fatal signal handlers. Ignore SIGPROF on startup.
996 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
997 in profiler.c, since sysdep.c now uses it.
999 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.
1000 Suggested by Eli Zaretskii in
1001 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.

1011 * profiler.c (record_backtrace, sigprof_handler_1):
1012 * alloc.c (Fgarbage_collect):
1013 * eval.c (interactive_p, Fsignal, eval_sub, Ffuncall, Fbacktrace)
1014 (Fbacktrace_frame): Adjust accordingly.
1016 2012-09-28 Glenn Morris <rgm@gnu.org>
1018 * eval.c (Frun_hook_with_args, Frun_hook_with_args_until_success)
1019 (Frun_hook_with_args_until_failure): Doc fixes.
1021 2012-09-28 Eli Zaretskii <eliz@gnu.org>
1023 * xdisp.c (syms_of_xdisp) <Qredisplay_internal>: Rename from
1024 Qautomatic_redisplay and change the symbol name. All users changed.
1026 2012-09-28 Tomohiro Matsuyama <tomo@cx4a.org>
1028 * profiler.c (sigprof_handler): Fix race condition.
1030 2012-09-28 Glenn Morris <rgm@gnu.org>

1034 2012-09-27 Paul Eggert <eggert@cs.ucla.edu>
1036 Check more robustly for timer_settime.
1037 * Makefile.in (LIB_TIMER_TIME): New macro.
1039 * atimer.c (alarm_timer, alarm_timer_ok, set_alarm, init_atimer):
1040 Use HAVE_TIMER_SETTIME, not SIGEV_SIGNAL, to decide whether to
1043 2012-09-26 Tomohiro Matsuyama <tomo@cx4a.org>
1045 * profiler.c (Fprofiler_cpu_start): Remove unnecessary flag SA_SIGINFO.
1047 2012-09-26 Juanma Barranquero <lekktu@gmail.com>

1051 2012-09-26 Paul Eggert <eggert@cs.ucla.edu>
1053 * character.h (MAYBE_UNIFY_CHAR): Remove.
1054 * charset.c, charset.h (maybe_unify_char): Now static.
1055 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
1056 Since this stuff is now private to charset.c, there's no need for
1057 a public macro and no need to inline by hand.
1059 2012-09-26 Tomohiro Matsuyama <tomo@cx4a.org>
1060 Stefan Monnier <monnier@iro.umontreal.ca>

1086 2012-09-25 Juanma Barranquero <lekktu@gmail.com>
1088 * makefile.w32-in ($(BLD)/callproc.$(O)): Update dependencies.
1090 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>
1092 Prefer POSIX timers if available.
1093 They avoid a race if the timer is too close to the current time.
1094 * atimer.c (alarm_timer, alarm_timer_ok) [SIGEV_SIGNAL]: New static vars.
1095 (set_alarm) [SIGEV_SIGNAL]: Use POSIX timers if available.

1101 CHAR_STRING_ADVANCE.
1102 (STRING_CHAR_ADVANCE_NO_UNIFY): Make it an alias of
1103 STRING_CHAR_ADVANCE.
1105 2012-09-25 Juanma Barranquero <lekktu@gmail.com>
1107 Move Vlibrary_cache to emacs.c and reset before dumping.
1109 * lisp.h (reset_image_types): Declare.
1110 [WINDOWSNT] (Vlibrary_cache): Declare.
1112 * image.c (reset_image_types): New function.
1114 * emacs.c [WINDOWSNT] (Vlibrary_cache): Move from w32.c.
1115 (syms_of_emacs) [WINDOWSNT] <Vlibrary_cache>: Initialize and staticpro.
1116 (Fdump_emacs): Reset Vlibrary_cache and image_types.

1119 (globals_of_w32) <Vlibrary_cache>: Do not initialize.
1121 * w32.h (Vlibrary_cache): Do not declare.
1123 2012-09-25 Eli Zaretskii <eliz@gnu.org>
1125 * w32proc.c (sys_signal): Handle all signals defined by the
1126 MS-Windows runtime, not just SIGCHLD. Actually install the signal
1127 handlers for signals supported by Windows. Don't override
1128 term_ntproc as the handler for SIGABRT.
1129 (sigaction): Rewrite to call sys_signal instead of duplicating its
1131 (sys_kill): Improve commentary.
1133 * w32.c (term_ntproc): Accept (and ignore) one argument, for
1134 consistency with a signature of a signal handler. All callers
1136 (init_ntproc): Accept an argument DUMPING. If dumping, don't
1137 install term_ntproc as a signal handler for SIGABRT, as that
1138 should be done by the dumped Emacs.
1140 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
1142 * w32select.c (term_w32select): Protect against repeated
1143 invocation by setting clipboard_owner to NULL after calling
1146 * emacs.c (shut_down_emacs, main): Adapt the calls to init_ntproc
1147 and term_ntproc to their modified signatures.
1149 * character.c (char_string, string_char): Remove calls to
1150 MAYBE_UNIFY_CHAR. See the discussion starting at
1151 http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00433.html
1154 2012-09-25 Chong Yidong <cyd@gnu.org>
1156 * xdisp.c (mode_line_inverse_video): Delete obsolete variable.
1158 2012-09-24 Stefan Monnier <monnier@iro.umontreal.ca>
1160 * bytecode.c (exec_byte_code): Signal an error instead of aborting,
1161 when encountering an unknown bytecode.
1163 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
1165 image.c, indent.c: Use bool for booleans.
1166 * dispextern.h (struct image_type): Members valid_p, load, init
1167 now return bool, not int. All uses changed.
1168 * image.c: Omit unnecessary static decls.
1169 (x_create_bitmap_mask, x_build_heuristic_mask):
1170 Return void, not int, since callers don't care about the return value.
1171 (x_create_bitmap_mask, define_image_type, valid_image_p)

1199 Use bool for booleans.
1201 2012-09-24 Chong Yidong <cyd@gnu.org>
1203 * chartab.c (Fset_char_table_default): Obsolete function removed.
1205 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
1207 Move pid_t related decls out of lisp.h.
1208 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
1209 (interruptible_wait_for_termination):
1210 Move these decls from lisp.h to syswait.h, since they use pid_t.
1211 Needed on FreeBSD; see Herbert J. Skuhra in
1212 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
1213 * callproc.c: Include syswait.h.

1230 * nsmenu.m (ns_update_menubar):
1231 * nsmenu.m, w32menu.c, xmenu.c (set_frame_menubar):
1232 * xfns.c (Fx_show_tip) [USE_GTK]:
1233 Use bool for boolean.
1234 * gtkutil.c (xg_update_frame_menubar):

1240 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
1242 * makefile.w32-in (BLOCKINPUT_H): Remove.

1259 2012-09-23 Eli Zaretskii <eliz@gnu.org>
1261 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
1262 fatal_error_backtrace.
1264 * w32proc.c (sys_kill): Undo last change: don't do anything when
1265 invoked to deliver SIGABRT to our own process. This is now
1266 handled by emacs_raise.
1268 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
1270 * w32term.c (w32_read_socket): Remove leftover reference to
1271 interrupt_input_pending.
1273 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
1275 Do not use SA_NODEFER.
1276 Problem reported by Dani Moncayo in
1277 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
1279 * sysdep.c (emacs_abort): Do not reset signal handler.
1280 * emacs.c (terminate_due_to_signal): Reset signal handler here.
1281 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
1282 wanted even on POSIXish hosts, and it doesn't work on Windows.
1284 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
1286 * xterm.c (x_term_init): Call fixup_locale before and after calling
1287 gtk_init (Bug#12392).
1289 2012-09-23 Chong Yidong <cyd@gnu.org>
1291 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
1292 Vdynamic_library_alist.
1294 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
1295 (Fgnutls_available_p): Caller changed.
1297 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
1298 (Flibxml_parse_xml_region): Likewise.
1300 * dispextern.h (struct image_type): Remove arg from init function.
1302 * image.c (Finit_image_library, lookup_image_type)
1303 (define_image_type): Remove now-unneeded second arg.
1304 (init_xpm_functions, init_png_functions, init_jpeg_functions)
1305 (init_tiff_functions, init_gif_functions, init_svg_functions):
1306 Arglist and w32_delayed_load calling convention changed.
1307 (gs_type): Remove init_gs_functions; there is no such function.
1308 (valid_image_p, make_image): Fix caller to lookup_image_type.
1310 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
1312 Simplify and avoid signal-handling races (Bug#12471).
1314 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
1315 Avoid recursive loop if there's a fatal error in the function itself.
1316 * atimer.c (pending_atimers):
1317 * blockinput.h: Don't include "atimer.h"; no longer needed.
1318 (interrupt_input_pending): Remove. All uses removed.
1319 pending_signals now counts both atimers and ordinary interrupts.
1320 This is less racy than having three separate pending-signal flags.
1321 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
1323 Rename from their upper-case counterparts BLOCK_INPUT,
1324 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
1325 INPUT_BLOCKED_P, and turn into functions. All uses changed.
1326 This makes it easier to access volatile variables more accurately.
1327 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
1328 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
1329 that's more reliable if the code is buggy and sets
1330 interrupt_input_blocked to a negative value. All uses changed.
1331 * atimer.c (deliver_alarm_signal):
1332 Remove. No need to deliver this to the parent; any thread can
1333 handle this signal now. All uses replaced by underlying handler.
1334 * atimer.c (turn_on_atimers):
1335 * dispnew.c (handle_window_change_signal):
1336 * emacs.c (handle_danger_signal):
1337 * keyboard.c (kbd_buffer_get_event):
1338 Don't reestablish signal handler; not needed with sigaction.
1339 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
1341 Rework to avoid unnecessary accesses to volatile variables.
1342 (UNBLOCK_INPUT_TO): Now a function.
1343 (totally_unblock_input, unblock_input): New decls.
1344 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
1345 (init_data): Remove. Necessary stuff now done in init_signal.
1346 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
1347 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
1348 (fatal_error_code): Remove; no longer needed.
1349 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
1350 it doesn't always backtrace. All uses changed. No need to reset
1351 signal to default, since sigaction and/or die does that for us now.
1352 Use emacs_raise (FOO), not kill (getpid (), FOO).
1353 (main): Check more-accurately whether we're dumping.
1354 Move fatal-error setup to sysdep.c
1355 * floatfns.c: Do not include "syssignal.h"; no longer needed.
1356 * gtkutil.c (xg_get_file_name, xg_get_font):
1357 Remove no-longer-needed signal-mask manipulation.
1358 * keyboard.c, process.c (POLL_FOR_INPUT):
1359 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
1360 * keyboard.c (read_avail_input): Remove.
1361 All uses replaced by gobble_input.
1362 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
1363 (kbd_buffer_store_event_hold, gobble_input):
1364 (record_asynch_buffer_change) [USABLE_SIGIO]:
1365 (store_user_signal_events):
1366 No need to mess with signal mask.
1367 (gobble_input): If blocking input and there are terminals, simply
1368 set pending_signals to 1 and return. All hooks changed to not
1369 worry about whether input is blocked.
1370 (process_pending_signals): Clear pending_signals before processing
1371 them, in case a signal comes in while we're processing.
1372 By convention callers now test pending_signals before calling us.
1373 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
1374 New functions, to support changes to blockinput.h.
1375 (handle_input_available_signal): Now extern.
1376 (reinvoke_input_signal): Remove. All uses replaced by
1378 (quit_count): Now volatile, since a signal handler uses it.
1379 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
1380 All callers changed. Block SIGINT only if not already blocked.
1381 Clear sigmask reliably, even if Fsignal returns, which it can.
1382 Omit unnecessary accesses to volatile var.
1383 (quit_throw_to_read_char): No need to restore sigmask.
1384 * keyboard.c (gobble_input, handle_user_signal):
1385 * process.c (wait_reading_process_output):
1386 Call signal-handling code rather than killing ourselves.
1387 * lisp.h: Include <float.h>, for...
1388 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
1389 (pending_signals): Now volatile.
1390 (syms_of_data): Now const if IEEE floating point.
1391 (handle_input_available_signal) [USABLE_SIGIO]:
1392 (terminate_due_to_signal, record_child_status_change): New decls.
1393 * process.c (create_process): Avoid disaster if memory is exhausted
1394 while we're processing a vfork, by tightening the critical section
1396 (send_process_frame, process_sent_to, handle_pipe_signal)
1397 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
1399 (send_process): No need for setjmp/longjmp any more, since the
1400 SIGPIPE stuff is now gone. Instead, report an error if errno
1402 (record_child_status_change): Now extern. PID and W are now args.
1403 Return void, not bool. All callers changed.
1404 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
1405 Remove. All uses removed. This bug should be fixed now in a
1407 (wait_for_termination_1): Use waitpid rather than sigsuspend,
1408 and record the child status change directly. This avoids the
1409 need to futz with the signal mask.
1410 (process_fatal_action): Move here from emacs.c.
1411 (emacs_sigaction_flags): New function, containing
1412 much of what used to be in emacs_sigaction_init.
1413 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
1414 caught by emacs, to make races less likely.
1415 (deliver_process_signal): Rename from handle_on_main_thread.
1417 (BACKTRACE_LIMIT_MAX): Now at top level.
1418 (thread_backtrace_buffer, threadback_backtrace_pointers):
1420 (deliver_thread_signal, deliver_fatal_thread_signal):
1421 New functions, for more-accurate delivery of thread-specific signals.
1422 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
1423 (deliver_arith_signal): Handle in this thread, not
1424 in the main thread, since it's triggered by this thread.
1425 (maybe_fatal_sig): New function.
1426 (init_signals): New arg DUMPING so that we can be more accurate
1427 about whether we're dumping. Caller changed.
1428 Treat thread-specific signals differently from process-general signals.
1429 Block all signals while handling fatal error; that's safer.
1430 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
1432 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
1433 Ignore SIGPIPE unless batch.
1434 (emacs_backtrace): Output backtrace for the appropriate thread,
1435 which is not necessarily the main thread.
1436 * syssignal.h: Include <stdbool.h>.
1437 (emacs_raise): New macro.
1438 * xterm.c (x_connection_signal): Remove; no longer needed
1439 now that we use sigaction.
1440 (x_connection_closed): No need to mess with sigmask now.
1441 (x_initialize): No need to reset SIGPIPE handler here, since
1442 init_signals does this for us now.
1444 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
1446 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
1447 background rect may be larger (Bug#12245).
1449 2012-09-23 Chong Yidong <cyd@gnu.org>
1451 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
1453 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
1455 * .gdbinit: Just stop at fatal_error_backtrace.
1456 See Stefan Monnier's request in
1457 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
1458 Remove no-longer-used query of system type.
1460 2012-09-22 Chong Yidong <cyd@gnu.org>
1462 * search.c (Freplace_match): Doc fix (Bug#12325).
1464 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
1466 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
1467 (Fline_end_position): Doc fix.
1469 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
1471 2012-09-22 Chong Yidong <cyd@gnu.org>
1473 * dispextern.h (struct image_type): Add new slot, storing a type
1474 initialization function.
1476 * image.c (define_image_type): Call the image initializer function
1477 if it is defined. Arguments and return value changed.
1478 (valid_image_p, make_image): Callers changed.
1479 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
1480 (gif_type, imagemagick_type, svg_type, gs_type):
1481 Add initialization functions.
1482 (Finit_image_library): Call lookup_image_type.
1483 (CHECK_LIB_AVAILABLE): Macro deleted.
1484 (lookup_image_type): Call define_image_type here, rather than via
1485 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
1486 (syms_of_image): Move define_image_type calls for xbm_type and
1487 pbm_type to lookup_image_type.
1489 2012-09-22 Eli Zaretskii <eliz@gnu.org>
1491 * keyboard.c (timer_check_2): Move calculation of 'timers' and
1492 'idle_timers' from here ...
1493 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
1494 lists, to avoid infloops when the timer does something stupid,
1495 like reinvoke itself with the same or smaller time-out.
1498 2012-09-22 Martin Rudalics <rudalics@gmx.at>
1500 * window.c (Fsplit_window_internal): Handle only Qt value of
1501 Vwindow_combination_limit separately.
1502 (Qtemp_buffer_resize): New symbol.
1503 (Vwindow_combination_limit): New default value.
1506 2012-09-22 Eli Zaretskii <eliz@gnu.org>
1508 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
1509 the new overlay string. (Bug#10159)
1511 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
1513 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
1514 or that fprintf is async-signal-safe. POSIX doesn't require
1517 2012-09-22 Chong Yidong <cyd@gnu.org>
1519 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
1522 2012-09-22 Kenichi Handa <handa@gnu.org>
1524 * composite.c (composition_reseat_it): Handle the case that a
1525 grapheme cluster is not covered by a single font (Bug#12352).
1527 2012-09-21 Chong Yidong <cyd@gnu.org>
1529 * image.c (define_image_type): Avoid adding duplicate types to
1530 image_types (Bug#12463). Suggested by Jörg Walter.
1532 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1534 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
1535 (print_load_command_name): Add case LC_DATA_IN_CODE.
1536 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
1538 2012-09-21 Glenn Morris <rgm@gnu.org>
1540 * eval.c (Frun_hook_with_args_until_success)
1541 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
1543 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
1545 * fileio.c (Ffile_selinux_context): Only call freecon when
1546 lgetfilecon succeeded.
1547 (Fset_file_selinux_context): Likewise. (Bug#12444)
1549 2012-09-21 Eli Zaretskii <eliz@gnu.org>
1551 * xdisp.c (try_window_reusing_current_matrix): Under bidi
1552 reordering, locate the cursor by calling set_cursor_from_row; if
1553 that fails, clear the desired glyph matrix before returning a
1554 failure indication to the caller. Fixes leaving garbled display
1555 when fast scrolling with a down-key. (Bug#12403)
1556 (compute_stop_pos_backwards): Fix a typo that caused crashes while
1557 scrolling through multibyte text.
1559 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
1561 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
1562 calling mark_vectorlike since that's the one that marks the window.
1563 (mark_discard_killed_buffers): Mark the final cdr.
1564 * window.h (struct window): Move prev/next_buffers to the
1565 non-standard fields.
1566 * window.c (make_window): Initialize prev/next_buffers manually.
1568 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
1570 Omit unused arg EXPECTED from socket hooks.
1571 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
1572 * nsterm.m (ns_term_init):
1573 * termhooks.h (struct terminal.read_socket_hook):
1574 * w32inevt.c (w32_console_read_socket):
1575 * w32term.c (w32_read_socket):
1576 * xterm.c (XTread_socket):
1577 Omit unused arg EXPECTED. All callers changed.
1578 (store_user_signal_events): Return void, not int, since callers no
1579 longer care about the return value. All uses changed.
1581 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
1583 * w32gui.h (XParseGeometry): Do not declare.
1585 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
1587 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
1588 Ignore 'expected'. See Eli Zaretskii in
1589 <http://bugs.gnu.org/12471#8> (last line).
1591 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
1592 (XParseGeometry): Now static. Substitute extremal values for
1593 values that are out of range.
1595 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
1597 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
1599 * nsfns.m (XParseGeometry): Remove.
1600 (Fx_create_frame): Call x_set_offset to correctly interpret
1601 top_pos in geometry.
1603 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
1604 (Fx_parse_geometry): If there is a space in string, call
1605 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
1607 2012-09-17 Eli Zaretskii <eliz@gnu.org>
1609 * search.c (scan_buffer): Use character positions in calls to
1610 region_cache_forward and region_cache_backward, not byte
1611 positions. (Bug#12196)
1613 * w32term.c (w32_read_socket): Set pending_signals to 1, like
1614 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
1616 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
1617 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
1618 emacs_blocked_malloc, now deleted.
1620 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
1622 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
1623 The workaround was for improving performance on Solaris 2.4, but
1624 is getting in the way now. Emacs will still work if someone is
1625 still running Solaris 2.4 in a museum somewhere; Sun dropped
1626 support for Solaris 2.4 in 2003.
1627 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
1628 * process.c (create_process) [HAVE_WORKING_VFORK]:
1629 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
1630 since Emacs no longer uses vfork on that platform.
1632 2012-09-17 Glenn Morris <rgm@gnu.org>
1634 * emacs.c: Use COPYRIGHT.
1636 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
1638 Remove configure's --without-sync-input option (Bug#12450).
1639 When auditing signal-handling in preparation for cleaning it up,
1640 I found that SYNC_INPUT has race conditions and would be a real
1641 pain to fix. Since it's an undocumented and deprecated
1642 configure-time option, now seems like a good time to remove it.
1643 Also see <http://bugs.gnu.org/11080#16>.
1644 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
1645 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
1646 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
1647 (malloc_hysteresis):
1648 (check_depth) [XMALLOC_OVERRUN_CHECK]:
1649 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
1650 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
1651 (dont_register_blocks, bytes_used_when_reconsidered)
1652 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
1653 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
1654 [!SYSTEM_MALLOC && !SYNC_INPUT]:
1655 Remove. All uses removed.
1656 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
1657 implementation, one that depends on whether the new macro
1658 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
1660 * atimer.c (run_timers, handle_alarm_signal):
1661 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
1662 (handle_async_input, process_pending_signals)
1663 (handle_input_available_signal, init_keyboard):
1664 * nsterm.m (ns_read_socket):
1665 * process.c (wait_reading_process_output):
1666 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
1667 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
1669 * xterm.c (XTread_socket):
1671 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
1672 * eval.c (handling_signal): Remove. All uses removed.
1673 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
1674 All uses replaced with the SYNC_INPUT version.
1675 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
1677 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
1680 * font.c (Ffont_shape_gstring): Remove unused local.
1682 2012-09-16 Glenn Morris <rgm@gnu.org>
1684 * Makefile.in (clean): No longer run nextstep's clean.
1686 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
1688 (ns-app): Move here from ns.mk, and simplify.
1689 (clean): Simplify nextstep entry.
1690 * ns.mk: Remove file.
1692 2012-09-17 Kenichi Handa <handa@gnu.org>
1694 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
1695 not covert the last few charactes.
1697 2012-09-16 Kenichi Handa <handa@gnu.org>
1699 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
1700 here, but just check the validity of glyphs in the glyph-string.
1702 2012-09-16 Martin Rudalics <rudalics@gmx.at>
1704 * window.c (Fwindow_parameter, Fset_window_parameter):
1705 Accept any window as argument (Bug#12452).
1707 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
1709 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
1710 to ns_term_init to avoid memory leak.
1712 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
1713 explicit retain/release.
1714 (ns_term_init): Only allow one display. Initialize outerpool and
1717 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
1719 Port _setjmp fix to POSIXish hosts as well as Microsoft.
1720 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
1721 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
1722 the Microsoft problem in a different way, by altering ../nt/config.nt.
1724 2012-09-15 Eli Zaretskii <eliz@gnu.org>
1739 * w16select.c: Remove inclusion of setjmp.h, as it is now included
1740 by lisp.h. This completes removal of setjmp.h inclusion
1741 erroneously announced in the previous commit. (Bug#12446)
1743 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
1746 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
1747 not defined as a macro. The latter happens on MS-Windows.
1750 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
1752 Port better to POSIX hosts lacking _setjmp (Bug#12446).
1753 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
1754 Some instances of '#include <setjmp.h>' removed, if the
1755 only reason for the instance was because "lisp.h" was included.
1756 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
1757 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
1758 and _longjmp with the new symbols. Emacs already uses _setjmp if
1759 available, so this change affects only POSIXish hosts that have
1760 sigsetjmp but not _setjmp, such as some versions of Solaris and
1761 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
1762 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
1763 (png_load_body) [HAVE_PNG]:
1764 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
1765 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
1766 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
1767 since PNG requires jmp_buf. This is the only exception to the
1768 general rule that we now use sys_setjmp and sys_longjmp.
1769 This exception is OK since this code does not change the signal
1770 mask or longjmp out of a signal handler.
1772 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
1774 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
1775 Include "syssignal.h", for 'main_thread'.
1777 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
1779 Avoid out-of-range marker position (Bug#12426).
1780 * insdel.c (replace_range, replace_range_2):
1781 Adjust markers before overlays, as suggested by comments.
1782 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
1783 Remove redundant check before calling offset_intervals.
1785 2012-09-14 Martin Rudalics <rudalics@gmx.at>
1787 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
1788 current buffer (Bug#12387).
1790 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
1792 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
1794 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
1796 Use a more backwards-compatible timer format (Bug#12430).
1797 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
1798 vector element, not from the 4th, since PSECS is now at the end.
1799 (Fcurrent_idle_time): Doc fix.
1801 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
1803 Function to mark objects and remove killed buffers at once.
1804 * alloc.c (discard_killed_buffers): Rename to ...
1805 (mark_discard_killed buffers) ... new name. Add marking
1806 of remaining objects. Fix comment. Adjust users.
1807 (mark_object): Do not touch frame buffer lists here.
1808 * frame.c (delete_frame): Reset frame buffer lists here.
1810 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
1812 Better workaround for GNOME bug when --enable-gcc-warnings.
1813 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
1814 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
1815 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
1817 Simplify SIGIO usage (Bug#12408).
1818 The code that dealt with SIGIO was crufty and confusing, e.g., it
1819 played tricks like "#undef SIGIO" but these tricks were not used
1820 consistently. Simplify mostly by not #undeffing standard symbols,
1821 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
1822 or not as we please) rather than "defined SIGIO" (standard symbol
1823 that we probably shouldn't #undef).
1824 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
1825 Modules that need it can include it.
1826 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
1827 * dispextern.h (ignore_sigio): New decl.
1828 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
1829 unconditionally, since it's now a no-op if !USABLE_SIGIO.
1830 * emacs.c (shut_down_emacs):
1831 * keyboard.c (kbd_buffer_store_event_hold):
1832 Use ignore_sigio rather than invoking 'signal' directly.
1833 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
1835 (FIONREAD, SIGIO): Do not #undef.
1836 (tty_read_avail_input): Use #error rather than a syntax error.
1837 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
1838 for I_PIPE, used by SETUP_SLAVE_PTY.
1839 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
1840 * sysdep.c (croak): Remove; no longer needed. This bit of
1841 temporary code, with Fred N. Fish's comment that it's temporary,
1842 has been in Emacs since at least 1992!
1843 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
1844 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
1845 * syssignal.h (croak): Remove decl.
1846 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
1847 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
1848 now that we're termios-only.
1849 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
1850 * term.c (dissociate_if_controlling_tty): Use #error rather than
1853 Work around GCC and GNOME bugs when --enable-gcc-warnings.
1854 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
1855 to work around GNOME bug 683906.
1856 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
1857 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
1858 This works around GCC bug 54561.
1860 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
1862 More fixes for 'volatile' and setjmp/longjmp.
1863 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
1864 * image.c (struct png_load_context) [HAVE_PNG]: New type.
1865 (png_load_body) [HAVE_PNG]:
1866 (jpeg_load_body) [HAVE_JPEG]:
1867 New function, with most of the old parent function's body.
1868 (png_load) [HAVE_PNG]:
1869 (jpeg_load) [HAVE_JPEG]:
1870 Invoke the new function, to avoid longjmp munging our locals.
1871 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
1872 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
1873 longjmp is passed 2, as the C standard doesn't guarantee this.
1874 Instead, store the failure code into mgr->failure_code.
1876 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
1878 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
1879 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
1880 (syms_of_keyboard): Remove support for unread-command-char.
1882 2012-09-12 Eli Zaretskii <eliz@gnu.org>
1884 * w32proc.c (sys_kill): If PID is our process ID and the signal is
1885 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
1886 violation. (Bug#12426)
1888 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
1890 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
1892 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
1894 * eval.c: Add `inhibit-debugger'.
1895 (Qinhibit_debugger): New symbol.
1896 (call_debugger): Bind it instead of Qdebug_on_error.
1897 (maybe_call_debugger): Test Vinhibit_debugger.
1898 (syms_of_eval): Define inhibit-debugger.
1899 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
1900 (syms_of_xdisp): Remove inhibit-debug-on-message.
1902 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
1904 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
1905 If a nonvolatile local variable is written before a _longjmp to
1906 the frame containing the variable, and is read after the _longjmp,
1907 the value read is indeterminate. Some local variables of type
1908 'struct handler' and 'struct catchtag' are used in this way, so
1909 mark each of their slots as volatile if the slot can be set before
1910 _longjmp and read afterwards.
1911 * lisp.h (struct handler): var and chosen_clause are now volatile.
1912 (struct catchtag): val, next, and pdlcount are now volatile.
1914 * bidi.c (bidi_push_it, bidi_pop_it):
1915 * fns.c (copy_hash_table):
1916 * image.c (define_image_type):
1917 * keyboard.c (kbd_buffer_store_event_hold):
1918 * process.c (Fprocess_send_eof):
1919 * xfaces.c (x_create_gc) [HAVE_NS]:
1920 * xgselect.c (xg_select):
1921 Prefer assignment to memcpy when either will do.
1923 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
1924 Use pointer-to-a-pointer to simplify and avoid a NILP check each
1925 time an item is removed. No need to mark this function 'inline';
1926 the compiler knows better than we do.
1928 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
1930 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
1931 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
1932 to change_frame_size (Bug#12388).
1933 (windowDidResize:): Pass YES to updateFrameSize.
1935 * nsterm.h: Add delay parameter to updateFrameSize.
1937 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
1939 Discard killed buffers from deleted window and frame objects.
1940 This reduces an amount of references to killed buffers and
1941 helps GC to reclaim them faster.
1942 * alloc.c (discard_killed_buffers): New function.
1943 (mark_object): Use it for deleted windows and frames.
1944 (mark_object): If symbol's value is set up for a killed buffer
1945 or deleted frame, restore it's global binding.
1946 * data.c (swap_in_global_binding): Add GC notice.
1947 (swap_in_symval_forwarding): Use convenient set_blv_where.
1948 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
1949 * window.h: ... to here.
1951 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
1953 Convenient macro to check whether the buffer is live.
1954 * buffer.h (BUFFER_LIVE_P): New macro.
1955 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
1956 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
1958 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1960 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
1961 composition cases (Bug#12364).
1963 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
1964 overhang of succeeding glyphs overlapping box cursor.
1966 * w32term.c (x_draw_glyph_string): Likewise.
1968 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
1970 Simplify, document, and port floating-point (Bug#12381).
1971 The porting part of this patch fixes bugs on non-IEEE platforms
1972 with frexp, ldexp, logb.
1973 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
1975 * floatfns.c: Simplify discussion of functions that Emacs doesn't
1976 support, by removing commented-out code and briefly listing the
1977 C89 functions excluded. The commented-out stuff was confusing
1978 maintenance, e.g., we thought we needed cbrt but it was commented out.
1979 (logb): Remove decl; no longer needed.
1980 (isfinite): New macro, if not already supplied.
1981 (isnan): Don't replace any existing macro.
1982 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
1983 are present on all C89 platforms.
1984 (Ffrexp): Do not special-case zero, as frexp does the right thing
1986 (Flogb): Do not use logb, as it doesn't have the desired meaning
1987 on hosts that use non-base-2 floating point. Instead, stick with
1988 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
1989 frexp, to avoid getting an unspecified result.
1991 * xdisp.c (Qinhibit_debug_on_message): Now static.
1993 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
1995 * nsterm.m (ns_update_begin): Set clip path to whole view by using
1996 NSBezierPath (Bug#12131).
1998 2012-09-10 Chong Yidong <cyd@gnu.org>
2000 * fns.c (Fdelq, Fdelete): Doc fix.
2002 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
2004 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
2005 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
2007 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
2009 * lisp.h (make_lisp_ptr): New macro to replace XSET.
2010 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
2013 2012-09-09 Eli Zaretskii <eliz@gnu.org>
2015 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
2016 left fringe if the window has a left margin. This avoids leaving
2017 traces of the cursor because its leftmost pixel is not drawn over.
2019 * dispnew.c (update_window_line): When the left margin area of a
2020 screen line is updated, set the redraw_fringe_bitmaps_p flag of
2021 that screen line. (Bug#12277)
2023 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
2025 Assume C89 or later for math functions (Bug#12381).
2026 This simplifies the code, and makes it a bit smaller and faster,
2027 and (most important) makes it easier to clean up signal handling
2028 since we can stop worring about floating-point exceptions in
2029 library code. That was a problem before C89, but the problem
2030 went away many years ago on all practical Emacs targets.
2031 * data.c, image.c, lread.c, print.c:
2032 Don't include <math.h>; no longer needed.
2033 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
2034 might be autoconfigured, as that never happens.
2036 * doprnt.c (DBL_MAX_10_EXP):
2037 * print.c (DBL_DIG):
2038 Remove. C89 or later always defines these.
2039 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
2040 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
2041 (arith_error, domain_error, domain_error2):
2042 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
2043 no longer needed -- we simply return what C returns. All uses removed.
2044 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
2046 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
2047 Remove. All uses expanded, as these macros are no longer used
2048 more than once and are now more trouble than they're worth.
2049 (Ftan): Use tan, not sin / cos.
2050 (Flogb): Assume C89 frexp.
2051 (fmod_float): Assume C89 fmod.
2052 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
2053 (init_floatfns): Remove. All uses removed.
2055 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
2057 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
2058 compositeToPoint for OSX < 10.6 (Bug#12390).
2060 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
2062 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
2063 This produces more-accurate results.
2065 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
2067 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
2068 changes (Bug#12088).
2070 2012-09-08 Chong Yidong <cyd@gnu.org>
2072 * syntax.c (Fstring_to_syntax): Doc fix.
2074 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
2076 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
2077 in the internal border.
2078 (x_set_window_size): Remove static variables and their usage.
2079 (ns_redraw_scroll_bars): Fix NSTRACE arg.
2080 (ns_after_update_window_line, ns_draw_fringe_bitmap):
2081 Remove fringe/internal border adjustment (Bug#11052).
2082 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
2083 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
2084 (ns_fix_rect_ibw): Remove.
2085 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
2086 (ns_dumpglyphs_box_or_relief): Ditto.
2087 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
2089 (ns_dumpglyphs_image): Ditto.
2090 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
2092 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
2093 their usage. Add fringe_extended_p and its use as in other terms.
2094 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
2095 scroll bar was removed.
2096 (updateFrameSize): New function.
2097 (windowDidResize): Move code to updateFrameSize and call it.
2099 * nsterm.h (EmacsView): Add updateFrameSize.
2101 2012-09-07 Chong Yidong <cyd@gnu.org>
2103 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
2105 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
2107 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
2109 More signal-handler cleanup (Bug#12327).
2110 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
2111 Problem introduced when merging patches. Noted by Eli Zaretskii in
2112 <http://bugs.gnu.org/12327#67>.
2113 * floatfns.c: Comment fix.
2114 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
2115 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
2116 and anyway the declaration is harmless even if SIGDANGER is not defined.
2117 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
2118 defined BROKEN_FIONREAD). systty.h formerly did this, but other
2119 source files not surprisingly expected syssignal.h to define, or
2120 not define, SIGIO, and it's cleaner to do it that way, for consistency.
2121 Include <sys/ioctl.h>, for FIONREAD.
2122 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
2123 This eliminates a problem whereby other files mysteriously had
2124 to include "syssignal.h" before including "systty.h" if they
2125 wanted to use "#ifdef SIGIO".
2127 2012-09-07 Eli Zaretskii <eliz@gnu.org>
2129 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
2131 * w32.c (sigemptyset): Empty the set.
2132 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
2134 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
2136 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
2138 * alloc.c (mark_buffer): Revert unsafe marking optimization.
2139 (mark_object): Likewise for frame objects.
2141 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
2143 * syssignal.h (handle_on_main_thread): Always declare,
2144 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
2145 This ports to platforms without HAVE_PTHREAD.
2147 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
2149 Signal-handler cleanup (Bug#12327).
2150 Emacs's signal handlers were written in the old 4.2BSD style with
2151 sigblock and sigmask and so forth, and this led to some
2152 inefficiencies and confusion. Rewrite these to use
2153 pthread_sigmask etc. without copying signal sets around. Also,
2154 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
2155 'signal', and instead use functions that do not attempt to take
2156 over the system name space. This patch causes Emacs's text
2157 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
2158 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
2159 Do not include <signal.h> or "syssignal.h", as these
2160 modules do not use signals.
2161 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
2162 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
2163 Do not include <signal.h>, as "syssignal.h" does that for us now.
2164 * atimer.c (sigmask_atimers): New function.
2165 (block_atimers, unblock_atimers): New functions,
2166 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
2168 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
2169 no longer needed here.
2170 * emacs.c (main): Inspect existing signal handler with sigaction,
2171 so that there's no need to block and unblock SIGHUP.
2172 * sysdep.c (struct save_signal): New member 'action', replacing
2173 old member 'handler'.
2174 (save_signal_handlers, restore_signal_handlers):
2175 Use sigaction instead of 'signal' to save and restore.
2176 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
2177 New function. All users of 'signal' modified to use set_sighandler
2178 if they're writeonly, and to use sys_signal if they're read+write.
2179 (emacs_sigaction_init, forwarded_signal): New functions.
2180 (sys_signal): Remove. All uses replaced by calls to sigaction
2181 and emacs_sigaction_init, or by direct calls to 'signal'.
2182 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
2183 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
2184 all uses replaced by pthread_sigmask etc. calls.
2185 * syssignal.h: Include <signal.h>.
2186 (emacs_sigaction_init, forwarded_signal): New decls.
2187 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
2188 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
2189 (sigmask, sys_sigmask): Remove; no longer needed.
2190 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
2191 (sigblock, sigunblock, sigfree):
2192 (sigsetmask) [!defined sigsetmask]:
2193 Remove. All uses replaced by pthread_sigmask.
2194 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
2195 no longer need to be replaced, and its typical old uses
2196 are now done via emacs_sigaction_init and sigaction.
2197 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
2198 (sys_sigdel): Remove; unused.
2199 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
2201 2012-09-06 Eli Zaretskii <eliz@gnu.org>
2203 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
2204 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
2206 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
2208 Explicitly mark buffer_defaults and buffer_local_symbols.
2209 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
2210 mark_local_symbols here.
2211 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
2212 since special buffers aren't marked here any more.
2213 (allocate_buffer): Chain new buffer with all_buffers here...
2214 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
2216 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
2217 (syms_of_buffer): Remove staticpro of the above.
2218 (init_buffer_once): Set names for buffer_defaults and
2219 buffer_local_symbols.
2221 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
2223 Use bool for booleans in font-related modules.
2224 * font.c (font_intern_prop, font_style_to_value)
2225 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
2226 (generate_otf_features, font_check_otf_features, font_check_otf)
2227 (font_match_p, font_list_entities, font_at):
2228 * fontset.c (fontset_id_valid_p, reorder_font_vector
2229 (fontset_find_font, Fset_fontset_font)
2230 (face_suitable_for_char_p) [0]:
2231 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
2232 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
2233 (m17n_flt_initialized, ftfont_shape_by_flt):
2234 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
2235 * nsfont.m (nsfont_draw):
2236 * w32font.c (w32font_draw):
2237 * w32term.c (x_draw_glyphless_glyph_string_foreground):
2238 Use bool for booleans.
2239 * font.h: Adjust to above API changes.
2240 (struct font, struct font_driver, struct font_driver_list):
2241 Use bool for booleans.
2242 (struct font): Remove useless member encoding_type.
2244 * fontset.c, xftfont.c: Omit unnecessary static decls.
2246 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
2248 * alloc.c (mark_object): Revert window marking code
2249 since it's unsafe for the Fset_window_configuration.
2251 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
2253 Fix race conditions with signal handlers and errno (Bug#12327).
2254 Be more systematic about preserving errno whenever a signal
2255 handler returns, even if it's not in the main thread. Do this by
2256 renaming signal handlers to distinguish between signal delivery
2257 and signal handling. All uses changed.
2258 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
2259 * data.c (deliver_arith_signal): Rename from arith_error.
2260 * dispnew.c (deliver_window_change_signal): Rename from
2261 window_change_signal.
2262 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
2263 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
2264 * keyboard.c (deliver_input_available_signal): Rename from
2265 input_available_signal.
2266 (deliver_user_signal): Rename from handle_user_signal.
2267 (deliver_interrupt_signal): Rename from interrupt_signal.
2268 * process.c (deliver_pipe_signal): Rename from send_process_trap.
2269 (deliver_child_signal): Rename from sigchld_handler.
2270 * atimer.c (handle_alarm_signal):
2271 * data.c (handle_arith_signal):
2272 * dispnew.c (handle_window_change_signal):
2273 * emacs.c (handle_fatal_signal, handle_danger_signal):
2274 * keyboard.c (handle_input_available_signal):
2275 * keyboard.c (handle_user_signal, handle_interrupt_signal):
2276 * process.c (handle_pipe_signal, handle_child_signal):
2277 New functions, with the actual signal-handling code taken from the
2278 original respective signal handlers, sans the sporadic attempts to
2279 preserve errno, since that's now done by handle_on_main_thread.
2280 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
2281 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
2282 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
2284 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
2285 Move initialization of main_thread to sysdep.c's init_signals.
2286 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
2287 our usage, and simplifies the mainline code.
2288 (record_child_status_change): New static function, as a helper
2289 for handle_child_signal, and with most of the old child handler's
2291 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
2292 (handle_child_signal): Use the above.
2293 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
2294 Moved here from emacs.c.
2295 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
2296 code moved here from emacs.c's main function.
2297 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
2298 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
2299 This lets callers save and restore errno properly.
2301 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
2303 Remove redundant or unused things here and there.
2304 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
2305 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
2306 * editfns.c (Fcompare_buffer_substrings): Likewise.
2307 * frame.h (struct terminal, struct font_driver_list):
2308 Remove redundant declarations.
2309 * window.h (Qleft, Qright): Likewise.
2311 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
2313 Do not mark objects from deleted buffers, windows and frames.
2314 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
2315 (mark_object): Likewise for windows and frames.
2317 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
2319 * alloc.c (valid_lisp_object_p): Treat killed buffers,
2320 buffer_defaults and buffer_local_symbols as valid objects.
2321 Return special value to denote them.
2323 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
2325 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
2326 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
2327 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
2328 (file_name_absolute_p, Fsubstitute_in_file_name):
2329 (check_executable, check_writable, Ffile_accessible_directory_p)
2330 (Fset_file_selinux_context, Fdefault_file_modes)
2331 (Finsert_file_contents, choose_write_coding_system)
2332 (Fwrite_region, build_annotations, a_write, e_write)
2334 * filelock.c (boot_time_initialized, get_boot_time)
2335 (get_boot_time_1, lock_file_1, within_one_second):
2336 * floatfns.c (in_float):
2337 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
2338 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
2339 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
2340 * lisp.h (struct Lisp_Hash_Table.cmpfn):
2341 * window.c (compare_window_configurations):
2342 Use bool for booleans.
2343 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
2344 (Fdefault_file_modes): Now mode_t, not int, for modes.
2345 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
2346 (internal_delete_file): Now returns void, not a (boolean) int,
2347 since nobody was looking at the return value.
2348 * lisp.h, window.h: Adjust to above API changes.
2350 * xdisp.c (set_message): Simplify and reindent last change.
2352 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
2354 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
2356 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
2358 * eval.c (call_debugger): Make the function non-static so that we
2359 can call it from set_message.
2361 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
2362 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
2364 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
2366 Give more-useful info on a fatal error (Bug#12328).
2367 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
2368 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
2369 of doing the work ourselves.
2370 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
2371 do most of the work.
2372 (fatal_error_backtrace): New function, taken from the guts
2373 of the old fatal_error_signal, but with a new option to output
2375 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
2376 info about the signal than just its number.
2377 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
2378 * sysdep.c: Include <execinfo.h>
2379 (emacs_backtrace): New function, taken partly from the previous
2380 code of the 'die' function.
2381 (emacs_abort): Call fatal_error_backtrace rather than abort.
2383 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
2385 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
2386 eager (load-time) macro-expansion.
2387 * lisp.mk (lisp): Add macroexp.
2389 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
2391 Simplify redefinition of 'abort' (Bug#12316).
2392 Do not try to redefine the 'abort' function. Instead, redo
2393 the code so that it calls 'emacs_abort' rather than 'abort'.
2394 This removes the need for the NO_ABORT configure-time macro
2395 and makes it easier to change the abort code to do a backtrace.
2396 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
2397 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
2398 Remove; sysdep.c's emacs_abort now takes its place.
2399 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
2400 'abort' changed to use 'emacs_abort'.
2401 * msdos.c (dos_abort) [defined abort]: Remove; not used.
2402 (abort) [!defined abort]: Rename to ...
2403 (emacs_abort): ... new name.
2404 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
2405 the place of the old 'abort' in emacs.c.
2406 * w32.c, w32fns.c (abort): Do not #undef.
2407 * w32.c (emacs_abort): Rename from w32_abort.
2409 2012-09-04 Eli Zaretskii <eliz@gnu.org>
2411 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
2412 offsets[j].dv, since the y axis of the screen coordinates points
2413 down, while the y axis of the font definition coordinates points
2414 up. This fixes display of Arabic diacritics such as KASRA and
2415 KASRATAN. (Bug#11860)
2417 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
2419 Be more systematic about _setjmp vs setjmp.
2420 * alloc.c (test_setjmp, mark_stack):
2421 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
2422 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
2423 (png_load, my_error_exit, jpeg_load):
2424 * process.c (send_process_trap, send_process):
2425 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
2426 The underscored versions are up to 30x faster on some hosts.
2427 Formerly, the code used setjmp+longjmp sometimes and
2428 _setjmp+_longjmp at other times, with no particular reason to
2429 prefer setjmp+longjmp.
2431 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
2433 Fix minor problem found by static checking.
2434 * buffer.c (Fdelete_all_overlays): Return nil.
2436 2012-09-03 Martin Rudalics <rudalics@gmx.at>
2438 * buffer.c (Fdelete_all_overlays): New function.
2440 2012-09-03 Chong Yidong <cyd@gnu.org>
2442 * gtkutil.c: Add extern decl for Qxft.
2444 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>

2458 All callers changed.
2459 * eval.c (interactive_p): Omit always-true boolean argument
2460 EXCLUDE_SUBRS_P. All callers changed.
2461 * dispextern.h, lisp.h: Reflect above API changes.
2462 * firstfile.c (dummy): Use the address of 'main', whose signature
2463 won't change, instead of the address of 'initialize', whose
2464 signature just changed from int to bool.
2465 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
2466 * msdos.c (fatal_error_in_progress): ... from here.
2467 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
2469 (redisplay_internal, unwind_redisplay): Simply clear
2470 REDISPLAYING_P when unwinding, instead of saving its previous,
2471 always-false value and then restoring it.
2473 Clean up some extern decls.
2474 Mostly, this hoists extern decls out of .c files and into .h files.
2475 That way, we're more likely to catch errors if the interfaces change.
2476 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
2477 declare xg_mark_data.
2478 * dispextern.h (x_frame_parm_handlers):
2480 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
2481 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
2482 (Qultra_bold, Qoblique, Qitalic):
2483 Move extern decl here from .c file.
2484 * alloc.c (xg_mark_data) [USE_GTK]:

2493 * process.c (QCfamily, QCfilter):
2494 * widget.c (free_frame_faces):
2495 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
2496 * xfont.c (x_clear_errors):
2497 * xterm.c (x_frame_parm_handlers):
2498 Remove now-redundant extern decls.
2499 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
2500 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
2502 * xfaces.c: Remove unnecessary static decls.
2503 * xterm.c (updating_frame): Remove decl of nonexistent object.
2505 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
2506 when building globals.h, as the objects that are not built on
2507 this host are not needed to compile C files on this host.
2509 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
2511 * gtkutil.h: Remove prototype for x_wm_set_size_hint.

2524 (format_time_string, general_insert_function)
2525 (make_buffer_string, make_buffer_string_both)
2526 (Fsubst_char_in_region, Ftranslate_region_internal, Fformat):
2527 * insdel.c (check_markers, gap_left, adjust_markers_for_insert)

2537 (get_property_and_range, compare_string_intervals)
2538 (set_intervals_multibyte_1, set_intervals_multibyte):
2539 * keyboard.c (decode_timer):
2540 Use bool for boolean.
2541 * intervals.h, lisp.h, systime.h: Reflect above API changes.
2542 * editfns.c (struct info): Use 1-bit unsigned bitfields for booleans.
2544 2012-09-02 Chong Yidong <cyd@gnu.org>
2546 * keymap.c (push_key_description): Print M-TAB as C-M-i
2549 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
2551 * makefile.w32-in (CCL_H, W32FONT_H): New macros.
2552 (ATIMER_H, FONT_H, $(BLD)/alloc.$(O), $(BLD)/callproc.$(O))

2557 ($(BLD)/w32font.$(O), $(BLD)/w32uniscribe.$(O)): Update dependencies.
2559 2012-09-01 Eli Zaretskii <eliz@gnu.org>
2561 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
2562 more than one grapheme cluster passed to the shaper: compute the
2563 offset adjustment values separately for each cluster. (Bug#11860)
2565 * image.c: Restore mistakenly removed inclusion of w32.h. Without
2566 it, GCC doesn't see prototypes of w32_delayed_load, and complains
2567 about implicit conversions from integer to pointer.
2569 2012-09-01 Daniel Colascione <dancol@dancol.org>
2571 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
2572 system used too early.
2574 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
2576 Better seed support for (random).
2577 * emacs.c (main): Call init_random.

2605 * process.c: Include TERM_HEADER instead of listing all possible
2606 window-system headers.
2608 * nsterm.h: Remove declarations now in frame.h.
2609 Define FRAME_X_SCREEN, FRAME_X_VISUAL.
2611 * menu.c: Include TERM_HEADER instead of listing all possible
2612 window-system headers.
2614 * keyboard.h: Declare ignore_mouse_drag_p whenever we have a
2617 * keyboard.c: Include TERM_HEADER instead of listing all possible
2618 window-system headers.
2620 * image.c: Include TERM_HEADER instead of listing all possible
2621 window-system headers. Declare Vlibrary_cache when compiling for
2624 * gtkutil.h (xg_list_node_): Include xterm.h to pick up needed
2625 window system declarations.
2627 * frame.h: Move common functions here: set_frame_menubar,
2628 x_set_window_size, x_sync, x_get_focus_frame,
2629 x_set_mouse_position, x_set_mouse_pixel_position,
2630 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,
2631 x_char_width, x_char_height, x_pixel_width, x_pixel_height,
2632 x_set_frame_alpha, x_set_menu_bar_lines, x_set_tool_bar_lines,

2651 the current window system; include in list of objects to link into
2654 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
2656 Remove mark_ttys function and fix tty_display_info initialization.
2657 * lisp.h (mark_ttys): Remove prototype.
2658 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
2659 to mark_ttys because all possible values of 'top_frame' slot are
2660 the frames which are reachable from Vframe_list.
2661 * term.c (mark_ttys): Remove.
2662 (init_tty): Safely initialize 'top_frame' slot with Qnil.
2664 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
2666 Change struct frame bitfields from unsigned char to unsigned.
2667 * frame.h (struct frame): Change type of 'display_preempted',
2668 'visible', 'iconified', 'has_minibuffer', 'wants_modeline',
2669 'auto_raise', 'auto_lower', 'no_split', 'explicit_name',
2670 'window_sizes_changed', 'mouse_moved' and 'pointer_invisible'
2671 bitfields from unsigned char to unsigned.
2673 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
2675 Remove unused member of struct x_output and struct w32_output.

2679 2012-08-30 Jan Djärv <jan.h.d@swipnet.se>
2681 * gtkutil.c (x_wm_set_size_hint): Use 1 col for base_width so it
2682 does not become zero (Bug#12234).
2684 2012-08-30 Paul Eggert <eggert@cs.ucla.edu>
2686 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
2687 for GCC 4.7.1 x86-64.
2689 2012-08-30 Glenn Morris <rgm@gnu.org>
2691 * lread.c (init_lread): For out-of-tree builds, only add the
2692 source directory's site-lisp dir to the load-path if it exists,
2693 consistent with in-tree builds. (Bug#12302)
2695 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>
2697 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize
2698 button_values to NULL. Call setStykeMask so dialogs get a close button.
2699 (windowShouldClose:): Set window_closed.
2700 (dealloc): New member, free button_values.
2701 (process_dialog:): Make member function. Remove window argument,
2702 replace window with self. Count buttons and allocate and store values
2704 (addButton:value:row:): value is int with the name tag. Call setTag
2705 with tag. Remove return self, declare return value as void.
2706 (addString:row:): Remove return self, declare return value as void.
2707 (addSplit): Remove return self, declare return value as void.
2708 (clicked:): Remove return self, declare return value as void.
2709 Set dialog_return to button_values[seltag]. Code formatting change.
2710 (initFromContents:isQuestion:): Adjust call to process_dialog.
2711 Code formatting change.
2712 (timeout_handler:): Set timer_fired to YES.
2713 (runDialogAt:): Set timer_fired to NO.
2714 Handle click on close button as quit.
2716 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
2717 Add window_closed and button_values. Add void as return value for
2718 add(Button|String|Split). addButton takes int instead of Lisp_Object.
2719 Add process_dialog as new member.
2721 2012-08-28 Eli Zaretskii <eliz@gnu.org>
2723 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it
2724 is not one of the heaps we manage. (Bug#12242)
2726 2012-08-28 Glenn Morris <rgm@gnu.org>

2739 * buffer.c (Fset_buffer_major_mode): Signal an error
2740 if the buffer is dead.
2741 (Fother_buffer, other_buffer_safely): Remove redundant
2744 2012-08-28 Dmitry Antipov <dmantipov@yandex.ru>
2746 Always use set_buffer_if_live to restore original buffer at unwind.
2747 * buffer.h (record_unwind_current_buffer): New function.
2748 * bytecode.c, dispnew.c, editfns.c, fileio.c, fns.c, insdel.c:
2749 * keyboard.c, keymap.c, minibuf.c, print.c, process.c, textprop.c:
2750 * undo.c, window.c: Adjust users.

2753 2012-08-28 Dmitry Antipov <dmantipov@yandex.ru>
2755 Fix usage of set_buffer_internal.
2756 * buffer.h (set_buffer_internal): Make it BUFFER_INLINE.
2757 * buffer.c (set_buffer_if_live): Use set_buffer_internal.
2758 * coding.c (decode_coding): Omit redundant test.
2759 * fileio.c (decide_coding_unwind): Likewise.
2760 * fns.c (secure_hash): Likewise.
2761 * insdel.c (modify_region): Likewise.
2762 * keyboard.c (command_loop_1): Likewise.
2763 * print.c (PRINTFINISH): Likewise.
2764 * xdisp.c (run_window_scroll_functions): Use set_buffer_internal.
2766 2012-08-27 Paul Eggert <eggert@cs.ucla.edu>

2785 Use bool for boolean.
2786 (clear_glyph_matrix_rows): Rename from enable_glyph_matrix_rows,
2787 and remove last int (actually boolean) argument, which was always 0.
2788 All callers changed.
2789 * dispextern.h, frame.h, lisp.h: Reflect above API changes.
2790 * dispextern.h (struct composition_it): Use bool for boolean.
2791 (struct glyph_matrix): Don't assume buffer sizes can fit in 'int'.
2792 (struct bidi_it): Use unsigned:1, not int, for boolean prev_was_pdf.
2793 * dired.c (file_name_completion):
2794 Use bool for boolean. (This was missed in an earlier change.)
2796 2012-08-27 Martin Rudalics <rudalics@gmx.at>
2798 * window.c (Fset_window_configuration): Revert first part of
2801 2012-08-27 Jan Djärv <jan.h.d@swipnet.se>
2803 * nsterm.h (NSPanel): New class variable dialog_return.
2805 * nsmenu.m (initWithContentRect:styleMask:backing:defer:):
2806 Initialize dialog_return.
2807 (windowShouldClose:): Use stop instead of stopModalWithCode.
2808 (clicked:): Ditto, and also set dialog_return (Bug#12258).
2809 (timeout_handler:): Use stop instead of abortModal. Send a dummy
2811 (runDialogAt:): Make ret Lisp_Object. Set it from dialog_return when

2856 Use bool for booleans.
2857 * coding.h, lisp.h: Reflect above API changes.
2858 * coding.c: Remove unnecessary static function decls.
2859 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
2860 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
2861 not a boolean 'int', since callers never look at the return value.
2862 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
2863 * coding.h (decoding_buffer_size, encoding_buffer_size)
2864 (emacs_mule_string_char): Remove unused extern decls.
2865 (struct iso_2022_spec, struct coding_system):
2866 Use 'unsigned int : 1' for boolean fields, since there's more than one.
2867 (struct emacs_mule_spec): Remove unused field 'full_support'.
2868 All initializations removed.
2869 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
2871 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
2873 Fix spare memory change (Bug#12286).
2874 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
2875 (valid_lisp_object_p): Likewise.
2877 2012-08-27 Martin Rudalics <rudalics@gmx.at>
2879 * window.c (Fset_window_configuration): Record any window's old
2880 buffer if it's replaced (see Bug#8789). If the new current
2881 buffer doesn't appear in the selected window, go to its old
2884 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
2886 Special MEM_TYPE_SPARE to denote reserved memory.
2887 * alloc.c (enum mem_type): New memory type.
2888 (refill_memory_reserve): Use new type for spare memory.
2889 This prevents live_cons_p and live_string_p from incorrect
2890 detection of uninitialized objects from spare memory as live.
2892 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
2895 * Makefile.in (.PHONY): versioclean -> versionclean.
2897 Remove unused external symbols.
2898 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
2899 * window.c (Qwindow_valid_p, decode_valid_window):
2900 Now static, not extern.
2901 * data.c (Qinterval): Remove; unused.
2902 (syms_of_data): Do not define 'interval'.
2903 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
2904 * window.h (decode_valid_window):
2907 * character.c, charset.c, chartab.c: Use bool for booleans.

2917 (char_table_set_range, optimize_sub_char_table)
2918 (map_sub_char_table):
2919 Use bool for boolean.
2920 * character.c (str_to_unibyte): Omit last boolean argument; it was
2921 always 0. All callers changed.
2922 * character.h, charset.h: Adjust to match previous changes.
2923 * character.h (char_printable_p): Remove decl of nonexistent function.
2924 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
2925 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
2926 are all boolean, so make them single-bit bitfields.
2928 * lisp.h (ASET): Remove attempt to detect side effects.
2929 It was meant to be temporary and it often doesn't work,
2930 because when IDX has side effects the behavior of IDX==IDX
2931 is undefined. See Stefan Monnier in
2932 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
2934 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
2936 * lisp.h (functionp): New function (extracted from Ffunctionp).
2937 (FUNCTIONP): Use it.
2938 * eval.c (Ffunctionp): Use it.
2940 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
2942 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
2943 as that's faster and simpler than static storage. Don't bother
2944 with the g_main_context_query overhead if g_main_context_pending
2945 says no events are pending.
2946 (gfds, gfds_size): Remove these static vars.
2947 (xgselect_initialize): Remove; no longer needed.
2948 All uses and decls removed.
2950 * emacs.c (fatal_error_signal_hook): Remove.
2951 All uses removed. This leftover from old code was always 0.
2953 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
2954 * casefiddle.c (casify_object, casify_region):
2955 * casetab.c (set_case_table):
2956 * category.c, category.h (word_boundary_p):
2957 * category.h (CHAR_HAS_CATEGORY):
2958 Use bool for booleans, instead of int.
2960 2012-08-25 Eli Zaretskii <eliz@gnu.org>
2962 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
2964 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
2966 On assertion failure, print backtrace if available.
2967 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
2968 (die) [ENABLE_CHECKING]: Print a backtrace if available.
2969 * Makefile.in (LIB_EXECINFO): New macro.
2972 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
2973 * bytecode.c (exec_byte_code):
2974 * callint.c (check_mark, Fcall_interactively):
2975 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
2976 (getenv_internal, sync_process_alive, call_process_exited):
2977 * lisp.h (USE_SAFE_ALLOCA):
2978 Use bool for booleans, instead of int.
2979 * lisp.h, process.h: Adjust prototypes to match above changes.
2980 * callint.c (Fcall_interactively): Don't assume the mark's
2981 offset fits in 'int'.
2983 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
2985 * buffer.c, buffer.h: Use bool for boolean.
2986 * buffer.c (reset_buffer_local_variables)
2987 (buffer_lisp_local_variables, Fset_buffer_modified_p)
2988 (Frestore_buffer_modified_p, Fset_buffer_multibyte):

2992 (mmap_enlarge, mmap_set_vars):
2993 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
2994 Use bool for booleans, instead of int.
2995 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
2996 since the 1-or-0 return value is always ignored anyway.
2997 (mmap_initialized_p):
2998 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
2999 * buffer.h, lisp.h: Adjust prototypes to match above changes.
3001 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
3003 * bidi.c: Use bool for boolean.
3004 This is a bit more readable, and makes the text segment of bidi.o
3005 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
3006 Presumably it's faster too.
3007 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
3009 (bidi_cache_find_level_change, bidi_cache_iterator_state)
3010 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)

3012 (bidi_explicit_dir_char, bidi_level_of_next_char)
3013 (bidi_find_other_level_edge, bidi_move_to_visually_next):
3014 Use bool for booleans, instead of int.
3015 * dispextern.h (bidi_init_it, bidi_paragraph_init)
3016 (bidi_unshelve_cache): Adjust decls to match code.
3018 2012-08-23 Martin Rudalics <rudalics@gmx.at>
3020 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
3023 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
3025 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
3026 * atimer.h: Include <stdbool.h>.
3028 2012-08-22 Dan Nicolaescu <dann@gnu.org>
3030 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
3031 compile time tests instead of run time tests on systems that do
3033 (FRAME_MAC_P): Remove leftover from deleted code.
3034 * frame.c (syms_of_frame): Remove leftover from deleted code.
3036 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
3038 * nsterm.m (insertText:): Don't clear modifiers if code is space.
3040 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
3042 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
3043 Otherwise, the compiler complains about (A?B:C) where B is void
3044 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
3045 (fontset_add): Return void, for FONTSET_ADD.
3047 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
3049 * alloc.c: Use bool for booleans.
3050 (gc_in_progress, abort_on_gc)
3051 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
3052 (dont_register_blocks) [GC_MALLOC_CHECK]:
3053 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
3054 (check_string_bytes, make_specified_string, memory_full)
3055 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
3056 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
3057 (mark_stack, valid_pointer_p, make_pure_string)
3058 (Fgarbage_collect, survives_gc_p, gc_sweep):
3059 Use bool for booleans, instead of int.
3060 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
3061 Remove unused local.
3062 * alloc.c (PURE_POINTER_P):
3063 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
3064 * editfns.c (Fformat):
3065 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
3067 * fns.c (sweep_weak_table):
3068 * lisp.h (suppress_checking, push_message, survives_gc_p)
3069 (make_pure_string, gc_in_progress, abort_on_gc):
3070 * lread.c (readchar, read1):
3071 * print.c (Fprin1_to_string):
3072 * xdisp.c (push_message):
3073 Use bool for booleans affected directly or indirectly by
3076 Make recently-introduced setters macros.
3077 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
3078 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
3079 (set_fontset_default, set_fontset_fallback): Rename from their
3080 upper-case counterparts, and make them functions rather than macros.
3081 This is more consistent with the other recently-introduced setters.
3082 These don't need to be inline, since they're local.
3084 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
3086 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
3087 the loop (Bug#12247).
3089 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
3091 * lisp.h (vcopy): Use memcpy rather than our own loop.
3092 This fixes a performance regression introduced by the recent
3093 addition of vcopy. This means 'vcopy' will need to be modified
3094 for a copying collector, but that's OK. Also, tighten the
3095 checking in the assertion.
3097 2012-08-21 Eli Zaretskii <eliz@gnu.org>
3099 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
3100 components for RTL text (Bug#11860). Adjust X-OFFSET of each
3101 non-base glyph for the width of the base character, according to
3102 what x_draw_composite_glyph_string_foreground expects.
3103 Generate WADJUST value according to composition_gstring_width's
3104 expectations, to produce correct width of the composed character.
3105 Reverse the sign of the DU offset produced by ScriptPlace.
3107 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
3109 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
3111 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
3113 Avoid direct writes to contents member of struct Lisp_Vector.
3114 * lisp.h (vcopy): New function to copy data into vector.
3115 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
3116 * fns.c (Ffillarray): Use ASET.
3117 * keyboard.c (timer_check_2): Use AREF and ASET.
3118 (append_tool_bar_item, Frecent_keys): Use vcopy.
3119 * lread.c (read_vector): Use ASET.
3120 * msdos.c (Frecent_doskeys): Use vcopy.
3121 * xface.c (Finternal_copy_lisp_face): Use vcopy.
3122 (Finternal_merge_in_global_face): Use ASET and vcopy.
3123 * xfont.c (xfont_list_pattern): Likewise.
3125 2012-08-21 Martin Rudalics <rudalics@gmx.at>
3127 * window.c (Fwindow_point): For the selected window always return
3128 the position of its buffer's point.
3129 (Fset_window_point): For the selected window always go in its
3130 buffer to the specified position.
3132 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
3134 Setter macros for fontsets.
3135 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
3136 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
3137 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
3140 2012-08-20 Glenn Morris <rgm@gnu.org>
3142 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
3143 Don't assume that `ln -f' works.
3145 2012-08-20 Eli Zaretskii <eliz@gnu.org>
3147 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
3148 and later about non-assignments with no effect. See discussion at
3149 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
3152 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
3154 Inline setter functions for Lisp_Objects slots of struct specbinding.
3155 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
3158 2012-08-20 Martin Rudalics <rudalics@gmx.at>
3160 * window.c (select_window): Always make selected window's buffer
3163 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
3165 Use AREF and ASET for docstrings of category tables.
3166 * category.h (CATEGORY_DOCSTRING): Use AREF.
3167 (SET_CATEGORY_DOCSTRING): Use ASET.

3191 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
3193 Rely on <config.h> + <unistd.h> to declare 'environ',
3194 as gnulib does this if the system doesn't.
3195 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
3196 Remove declaration. MS-Windows declares it on stdlib.h which is

4064 2012-08-04 Eli Zaretskii <eliz@gnu.org>
4066 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
4067 * w32.c (init_environment): Change the default values of many
4068 environment variables in dflt_envvars[] to NULL, to avoid pushing
4069 them into environment when they were not already defined.
4070 Remove the code that deletes site-lisp subdirectories from the default
4071 value of EMACSLOADPATH, as it is no longer needed.
4072 (check_windows_init_file): Now external, not static.
4073 Use Vload_path as is, without adding anything, as this function is now
4074 called when Vload_path is already set up.
4076 * w32.h (check_windows_init_file): Add prototype.
4078 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build
4079 directory, ignore the /*/i386/ tail in Vinvocation_directory, for
4080 compatibility with Posix platforms.
4081 (main): Move the call to check_windows_init_file to here from
4083 (decode_env_path) [WINDOWSNT]: Expand the %emacs_dir%/ prefix, if
4084 any, in the DEFALT argument into the root of the Emacs build or
4085 installation tree, as appropriate.
4087 * callproc.c (init_callproc_1): Call decode_env_path instead of
4088 doing its equivalent by hand.
4089 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
4090 the code that sets Vexec_path run on MS-Windows.
4092 * lread.c (init_lread): Add comments to #ifdef's.
4094 * msdos.c (dos_set_window_size, IT_update_begin)
4095 (IT_frame_up_to_date, IT_set_frame_parameters): Use FVAR and WVAR
4096 instead of direct references.
4098 2012-08-04 Paul Eggert <eggert@cs.ucla.edu>
4100 Export DEFAULT_REHASH_* to GDB.
4101 * lisp.h (DEFAULT_REHASH_THRESHOLD, DEFAULT_REHASH_SIZE):
4102 Now constants, not macros.
4104 2012-08-03 Paul Eggert <eggert@cs.ucla.edu>
4106 Remove unnecessary casts involving pointers.
4107 These casts are no longer needed now that we assume C89 or later,
4108 since they involve casting to or from void *.
4109 * alloc.c (make_pure_string, make_pure_c_string, pure_cons)
4110 (make_pure_float, make_pure_vector):
4111 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP):

4120 (x_get_window_property, x_get_window_property_as_lisp_data):
4121 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
4122 Remove unnecessary pointer casts.
4123 * alloc.c (record_xmalloc): New function.
4124 * lisp.h (record_xmalloc): New decl.
4125 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
4126 more like a function. This is because the pointer cast is not
4127 needed. All uses changed.
4128 * print.c (print_string, print_error_message): Avoid length recalc.
4130 Improve fix for macroexp crash with debugging (Bug#12118).
4131 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
4132 ARRAY_MARK_FLAG when checking subscripts, because ASET is
4133 not supposed to be invoked from the garbage collector.
4134 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
4135 (gc_aset): New function, which is like ASET but can be
4136 used in the garbage collector.
4137 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)
4138 (set_hash_index): Use it instead of ASET.

4147 <g_b_init_create_symbolic_link>: New static flags.
4148 (globals_of_w32): Initialize them to zero.
4149 (GetSecurityInfo_Proc, CreateSymbolicLink_Proc): New typedefs.
4150 (map_w32_filename): Improve commentary. Simplify switch.
4151 (SYMBOLIC_LINK_FLAG_DIRECTORY): Define if not defined in system
4152 headers (most versions of MinGW w32api don't).
4153 (get_security_info, create_symbolic_link)
4154 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
4156 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
4157 in the argument file name.

4160 (sys_rename): Diagnose renaming of a symlink when the user doesn't
4161 have the required privileges.
4162 (get_file_security_desc_by_name): Rename from
4163 get_file_security_desc.
4164 (stat_worker): New function, with most of the guts of 'stat', and
4165 with addition of handling of symlinks and support for 'lstat'.
4166 If possible, get file's attributes and security information by
4167 handle, not by name. Produce S_IFLNK bit for symlinks, when
4168 called from 'lstat'.
4169 (stat, lstat): New functions, call 'stat_worker'.
4170 (symlink, readlink, careadlinkat): Rewritten to create and resolve
4171 symlinks when the underlying filesystem supports them.
4173 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
4175 Fix macroexp crash on Windows with debugging (Bug#12118).
4176 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
4177 checking subscripts; problem introduced with the recent
4178 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
4179 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
4180 since it's used in non-static inline functions now.
4182 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
4183 Don't assume buffer size fits in 'int'. Remove unused local.
4185 Use C99-style 'extern inline' if available.

4197 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
4198 * alloc.c (LISP_INLINE):
4199 * buffer.c (BUFFER_INLINE):
4200 * category.c (CATEGORY_INLINE):
4201 * character.c (CHARACTER_INLINE):
4202 * charset.c (CHARSET_INLINE):
4203 * composite.c (COMPOSITE_INLINE):
4204 * dispnew.c (DISPEXTERN_INLINE):
4205 * sysdep.c (SYSTIME_INLINE):
4206 Define to EXTERN_INLINE, so that the corresponding functions
4207 are compiled into code.
4208 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
4209 (INLINE_HEADER_END): New macros.
4210 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

4230 hard-coding the path separator.
4232 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
4234 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
4235 This how ASET and AREF are supposed to work, and makes
4236 it easier to think about future improvements. See
4237 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
4238 * charset.h (set_charset_attr): New function.
4239 All lvalue-style uses of CHARSET_DECODER etc. changed to use it.
4240 * lisp.h (ASET): Rewrite so as not to use AREF in an lvalue style.

4619 (fill_queue): Call w32_read_console_input instead of ReadConsoleInput.
4620 (w32_kbd_patch_key, key_event): Use the codepage returned by
4621 GetConsoleCP, rather than the ANSI codepage returned by GetLocaleInfo.

4653 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
4654 enumeration constants, as PURE and HEAP are too general, and clash
4655 with other headers and sources, such as gmalloc.c and the
4656 MS-Windows system headers. All users changed.
4658 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
4660 Revert last save_excursion_save and save_excursion_restore changes.
4661 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

4674 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
4675 arms of an 'if', not using conditional expressions; otherwise GDB
4676 complains about the types in the unevaluated arm when the argument
4677 is an integer literal.
4678 (xgetint): Simplify expression.
4679 * alloc.c (gdb_make_enums_visible): New constant. This ports to
4680 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
4681 Zaretskii in <http://bugs.gnu.org/12036#13>.
4682 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
4683 needed now that we have gdb_make_enums_visible.
4684 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
4685 (enum enum_USE_LSB_TAG):
4686 New enum types, packaging up enums that need to be exported to GDB.

4710 * lisp.h (struct Lisp_Excursion): New data type.
4711 (PVEC_EXCURSION): New pseudovector type.
4712 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
4713 to deal with it. Adjust comments.

4728 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
4729 emacs.c, as this is a more-suitable home. Had this been done earlier
4730 the fix for 12036 would have avoided some of the problems noted in
4731 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
4732 would have been more obvious.
4733 * emacs.c: Do not include <verify.h>; no longer needed.
4734 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
4735 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
4736 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):

4742 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
4743 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
4744 not be usable in #if. This simplifies things.
4746 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
4748 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.

4753 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
4754 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
4755 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
4756 Adjust to changes in lisp.h and emacs.c, by using
4757 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
4758 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
4759 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
4760 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
4761 instead of gdb_valbits.
4762 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
4763 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
4764 instead of gdb_array_mark_flag.
4765 (xboolvector): Get size from $->size, not $->header.size.
4766 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
4767 (xreload, hook-run, hookpost-run): Remove.
4768 * emacs.c: Include <verify.h>.
4769 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
4770 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
4772 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
4773 (gdb_USE_LSB_TAG): New enum constants.
4774 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
4775 Also define these as enum constants, so they're visible to GDB.
4776 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
4777 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
4778 as constants, so they're visible to GDB.

4780 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
4781 Now enum constants, not macros, so they're visible to GDB.
4782 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
4783 more convenient now. All uses changed.
4784 (VALMASK) [USE_LSB_TAG]: Also define in this case.
4785 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
4787 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

4792 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
4794 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
4795 add argument, tune behavior, and adjust all callers.
4797 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
4799 Use typedef for EMACS_INT, EMACS_UINT.
4800 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
4801 than macros. This simplifies debugging in the usual case, since
4802 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
4803 and it allows expressions involving EMACS_INT casts.
4804 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
4806 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

4816 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
4818 Adjust buffer text indirection counters at the end of Fkill_buffer.
4819 * buffer.c (Fkill_buffer): Adjust indirection counters when the
4820 buffer is definitely dead. This should really fix an issue reported
4821 by Christoph Scholtes again. (Bug#12007).
4822 (init_buffer_once): Initialize indirection counters of
4823 buffer_defaults and buffer_local_symbols (for sanity and safety).
4825 2012-07-24 Eli Zaretskii <eliz@gnu.org>
4827 * xdisp.c (init_iterator): Don't compute dimensions of truncation
4828 and continuation glyphs on tooltip frames, leave them at zero.

4831 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
4833 Simplify copy_overlay.
4834 * buffer.c (copy_overlay): Simplify. Use build_marker.

4840 or invalid. (Bug#12025)
4842 * window.c (decode_any_window): Disable CHECK_LIVE_FRAME test, as
4843 it signals an error when a tooltip frame is being created.
4845 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
4847 Cleanup miscellaneous objects allocation and initialization.

4854 (build_overlay): Add prototype.
4856 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
4858 Swap buffer text indirection counters in Fbuffer_swap_text.
4859 * buffer.c (Fbuffer_swap_text): Swap indirections too.
4860 This avoids crash reported by Christoph Scholtes at
4861 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
4863 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
4865 * nsmenu.m (Popdown_data): New struct.
4866 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
4868 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
4869 (initWithContentRect): Make imgView and contentView non-static
4870 and autorelease them. Also autorelease img and matrix (Bug#12005).
4871 (dealloc): Remove (Bug#12005).
4873 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
4875 Adjust consing_since_gc when objects are explicitly freed.
4876 * alloc.c (GC_DEFAULT_THRESHOLD): New macro.
4877 (Fgarbage_collect): Use it. Change minimum to 1/10 of default.
4878 (free_cons, free_misc): Subtract object size from consing_since_gc.
4880 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>

4884 (live_buffer, set_marker_internal): New function.
4885 (Fset_marker, set_marker_restricted): Use set_marker_internal.

4888 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
4890 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
4891 as it's limited by the amount of memory, not by INT_MAX.
4893 2012-07-21 Eli Zaretskii <eliz@gnu.org>
4895 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
4896 in special-event-map. See the discussion at

5619 * s/aix4-2.h (unix): Remove; no longer needed.
5621 EMACS_TIME simplification (Bug#11875).
5622 This replaces macros (which typically do not work in GDB)
5623 with functions, typedefs and enums, making the code easier to debug.
5624 The functional style also makes code easier to read and maintain.
5625 * systime.h: Include <sys/time.h> on all hosts, not just if
5626 WINDOWSNT, since 'struct timeval' is needed in general.

5639 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
5640 not functions. All uses rewritten to use the following, respectively:
5641 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
5642 (add_emacs_time, sub_emacs_time): New functions.
5643 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.

5666 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
5667 Prefer snprintf to strncpy.
5668 * nsterm.m (ns_term_init):
5669 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
5670 * nsterm.m (ns_term_init):
5671 Avoid the need for strncpy, by using build_string or
5672 make_unibyte_string directly. Use dtoastr, not snprintf.
5673 * process.c (Fmake_network_process): Diagnose service names that
5674 are too long, rather than silently truncating them or creating
5675 non-null-terminated names.
5676 (Fnetwork_interface_info): Likewise, for interface names.
5677 * sysdep.c (system_process_attributes) [GNU_LINUX]:
5678 Prefer sprintf to strncat.

5692 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
5693 where argument type is known to be a Lisp_Cons.

5748 O_RDONLY already includes it).
5750 Stop ns builds setting the EMACSLOADPATH environment variable.
5751 * nsterm.m (ns_load_path): Rename from ns_init_paths.
5752 Now it does not set EMACSLOADPATH, just returns the load-path string.
5753 * nsterm.h: Update accordingly.
5754 * lread.c [HAVE_NS]: Include nsterm.h.
5755 (init_lread) [HAVE_NS]: Use ns_load_path.

5765 (ns_init_paths): Do not set EMACSPATH.

5818 (ns_init_paths): Do not set EMACSDATA, EMACSDOC.
5819 * nsterm.h (ns_etc_directory): Add it.
5820 * callproc.c [HAVE_NS]: Include nsterm.h.
5821 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
5823 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
5825 Move marker debugging code under MARKER_DEBUG.
5826 * marker.c (MARKER_DEBUG): Move marker debugging code under
5827 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
5828 for bootstrap with --enable-checking (~3x slowdown reported
5829 by Juanma Barranquero <lekktu@gmail.com>).
5830 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
5832 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
5834 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
5835 See <http://bugs.gnu.org/11825#29>.
5837 2012-07-08 Eli Zaretskii <eliz@gnu.org>
5839 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
5840 has no font, use the frame's font. (Bug#11813)
5841 (display_line): Add commentary about displaying truncation glyphs
5843 (produce_special_glyphs): Move here from term.c.
5845 * term.c (produce_special_glyphs): Move to xdisp.c.
5847 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
5850 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
5852 * xdisp.c (display_line): Avoid warning about implicit declaration
5855 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
5857 * lisp.h: Remove empty conditional.
5859 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
5861 * lread.c (load_path_check): Now static.
5863 Fix some minor --with-ns problems found by static checking.
5864 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
5865 (x_set_font) [!HAVE_X_WINDOWS]:
5866 * image.c (xpm_load_image) [HAVE_NS]:
5867 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
5868 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
5869 Remove unused local.
5870 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
5871 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
5872 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
5873 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
5874 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
5875 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
5876 Fix pointer signedness problem.
5877 * xfaces.c (FRAME_X_FONT_TABLE):
5878 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
5880 2012-07-07 Glenn Morris <rgm@gnu.org>
5882 * lread.c (load_path_check): New function, split from init_lread.
5883 (init_lread): Reorganize. Motivation:
5884 If EMACSLOADPATH is set, check/warn about that rather than the
5885 defaults, which we are not going to use. Hence we can remove
5886 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
5887 Don't warn if site-lisp directories are missing.
5888 If not installed, start from a blank load-path, since
5889 PATH_LOADSEARCH refers to the eventual installation directories.
5891 2012-07-07 Eli Zaretskii <eliz@gnu.org>
5893 Support truncation and continuation glyphs on GUI frames, when
5894 fringes are disabled. (Bug#11832)
5895 * xdisp.c (init_iterator): Get dimensions of truncation and
5896 continuation glyphs even if on GUI frames.
5897 Adjust it->last_visible_x on GUI frames when the left or right fringes,
5898 or both, are absent.
5899 (start_display, move_it_in_display_line_to): Handle the case of a
5900 GUI frame without a fringe to display continuation or truncation
5902 (insert_left_trunc_glyphs): Support GUI frames: make sure
5903 truncation glyphs overwrite enough glyphs from the current line to
5904 have sufficient space in pixels.
5905 (display_line): Support truncation and continuation glyphs on GUI
5906 frames. If some spare pixels are left on the line after inserting
5907 the truncation glyphs, fill that space with a stretch glyph of a
5908 suitably computed width.
5910 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
5911 produce_glyphs, to support GUI sessions.
5913 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
5915 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
5917 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
5919 Do not require float-time's arg to fit in time_t (Bug#11825).
5920 This works better on hosts where time_t is unsigned, and where
5921 float-time is applied to the (negative) difference between two times.
5922 * editfns.c (decode_time_components): Last arg is now double *,
5923 not int *, and means to store all the result as a double, without
5924 worrying about whether the seconds part fits in time_t.
5925 All callers changed.
5926 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
5927 All callers changed.
5928 (Ffloat_time): Do not fail merely because the specified time falls
5929 outside of time_t range.
5931 2012-07-07 Glenn Morris <rgm@gnu.org>
5933 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
5934 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):

5937 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
5939 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
5940 Update dependencies.
5942 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
5944 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
5946 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
5947 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
5948 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
5949 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
5950 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
5951 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
5953 * xfont.c (compare_font_names): Redo to omit the need for casts.
5955 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
5957 * xfns.c (Fx_change_window_property): Doc fix.
5958 * w32fns.c (Fx_change_window_property): Doc fix.
5960 * w32fns.c (Fx_window_property): Accept the same arguments as the
5961 X Windows version. Doc fix.
5962 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
5964 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
5965 Eli Zaretskii <eliz@gnu.org>
5967 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
5968 Windows-specific code from nt/config.nt moved here.
5969 Obsolete settings removed.
5971 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
5973 * process.c: Avoid unnecessary calls to gettime.
5974 (wait_reading_process_output): Don't get the time of day
5975 when gobbling data immediately and not waiting, as there's no need
5976 for it in that case. This removes a FIXME.
5978 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
5980 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
5981 is defined (Bug#11768).
5983 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
5985 Fix marker debugging code.
5986 * marker.c (byte_char_debug_check): Do not perform the check
5987 if buffer is not multibyte.
5988 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
5989 Call byte_char_debug_check with correct arguments.
5991 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
5993 Compile marker debugging code only if ENABLE_CHECKING is defined.
5994 * marker.c (byte_char_debug_check, count_markers):
5995 Use only if ENABLE_CHECKING is defined.
5996 (byte_debug_flag): Remove.
5997 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
5998 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
6000 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6002 Avoid code repetition in marker-related functions.
6003 * marker.c (attach_marker): New function.
6004 (Fset_marker, set_marker_restricted, set_marker_both)
6005 (set_marker_restricted_both): Use it.
6006 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
6007 Consistently rename charno to charpos.
6008 (marker_position): Add eassert.
6009 (marker_byte_position): Convert to eassert.
6011 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

6021 * lisp.h (build_marker): New prototype.
6022 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
6023 * composite.c (autocmp_chars): Likewise.
6024 * editfns.c (buildmark): Remove.
6025 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
6026 (save_restriction_save): Use build_marker.
6027 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
6028 * window.c (save_window_save): Likewise.
6030 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6032 Do not use Fdelete_overlay in delete_all_overlays
6033 to avoid redundant calls to unchain_overlay.
6034 * buffer.c (drop_overlay): New function.
6035 (delete_all_overlays, Fdelete_overlay): Use it.
6036 * minibuf.c (get_minibuffer): Fix comment.
6038 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
6040 Port to OpenBSD 5.1 amd64.
6041 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
6042 This is needed for OpenBSD, and should be harmless on all BSD systems.
6043 Also, include <sys/sysctl.h>, as it should be available on all
6044 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
6045 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
6046 use p_pid member, not kp_proc.pid.
6048 2012-07-06 Glenn Morris <rgm@gnu.org>
6050 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
6052 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
6054 More xmalloc and related cleanup.
6055 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
6056 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:
6057 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, fns.c:

6061 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:
6062 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
6063 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
6065 Omit needless casts involving void * pointers and allocation.
6066 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
6067 as the former is more robust if P's type is changed.
6068 Prefer xzalloc to xmalloc + memset 0.
6069 Simplify malloc-or-realloc to realloc.
6070 Don't worry about xmalloc returning a null pointer.
6071 Prefer xstrdup to xmalloc + strcpy.
6072 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
6074 * keyboard.c (apply_modifiers_uncached): Prefer local array to
6075 alloca of a constant.
6077 2012-07-05 Eli Zaretskii <eliz@gnu.org>
6079 * xdisp.c (display_line): Fix horizontal pixel coordinates when
6080 hscroll is larger than the line width. Fixes long and futile
6081 looping inside extend_face_to_end_of_line (on a TTY) producing
6082 glyphs that are not needed and thrown away.
6084 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
6086 * marker.c (set_marker_restricted_both): Simplify by using
6089 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
6091 * editfns.c (region_limit): Simplify by using clip_to_bounds.

6098 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
6099 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
6100 followed by gtk_box_set_homogeneous (Bug#11768).
6101 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
6102 (update_theme_scrollbar_width, xg_create_scroll_bar):
6103 Use gtk_scrollbar_new (Bug#11768).
6104 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
6105 (is_box_type): New function (Bug#11768).
6106 (xg_tool_item_stale_p): Call is_box_type.
6107 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
6108 with default display (Bug#11768).
6110 2012-07-05 Eli Zaretskii <eliz@gnu.org>
6112 * xdisp.c (window_hscroll_limited): New function.
6113 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
6114 coordinates when window's hscroll is set to insanely large
6117 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
6119 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
6120 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
6122 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
6125 * lisp.h (xzalloc): New prototype. Omit needless casts.
6126 * alloc.c (xzalloc): New function. Omit needless casts.
6127 * charset.c: Omit needless casts. Convert all calls to
6128 xmalloc with following memset to xzalloc.

6178 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
6180 * fileio.c (time_error_value): Check the right error number.
6181 Problem reported by Troels Nielsen in
6182 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
6184 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
6186 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
6187 This should be fixed in a better way; see Eli Zaretskii in
6188 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
6189 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
6191 * fileio.c (time_error_value): Rename from special_mtime.
6192 The old name's problems were noted by Eli Zaretskii in
6193 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
6195 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
6196 This variable's comment says Emacs needs at least one GDB-visible
6197 symbol of type enum pvec_type, to work around GDB problems.
6198 The symbol's value doesn't matter.
6200 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
6201 that causes compilation to fail on pre-C99 compilers.
6203 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
6205 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
6206 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
6208 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
6210 * buffer.c (init_buffer_once): Fix initialization of
6211 headers for buffer_defaults and buffer_local_symbols.
6212 Reported by Juanma Barranquero <lekktu@gmail.com>.
6214 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
6216 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
6217 * lisp.h (enum pvec_type): Use fewer bits.
6218 (PSEUDOVECTOR_SIZE_BITS): New constant.
6219 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
6220 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
6221 change in pvec_type.
6222 (PSEUDOVECTOR_TYPEP): New macro.
6223 (TYPED_PSEUDOVECTORP): Use it.
6224 * fns.c (internal_equal): Adapt code to extract pvectype.
6225 * emacs.c (gdb_pvec_type): Update type.
6226 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
6227 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
6228 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
6229 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
6230 (sweep_vectors): Use it. Use local var `total_bytes' instead of
6231 abusing vector->header.next.nbytes.
6232 (live_vector_p): Use PVEC_TYPE.
6233 (mark_object): Adapt code to extract pvectype. Use switch.
6235 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
6237 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
6238 Tighten new eassert a bit.
6240 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
6242 Fix compilation with --enable-gcc-warnings and -O1
6244 * doprnt.c (doprnt): Change type of tem to int, initialize
6245 to avoid compiler warning. Add eassert.
6246 * search.c (simple_search): Initialize match_byte to avoid
6247 compiler warning. Add eassert.
6249 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
6251 Avoid weird behavior with large horizontal scrolls.
6252 Without this change, for example, large hscroll values would
6253 mess up Emacs's display on Fedora 15 x86, presumably due to
6254 overflows in int calculations in the display code.
6255 Also, if buffers had long lines, Emacs would freeze.
6256 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
6257 (set_window_hscroll): New function, containing the old guts of
6258 Fset_window_hscroll. Return the clipped value.
6259 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
6260 This avoids the need to check against PTRDIFF_MAX.
6262 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
6264 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
6266 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
6268 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
6270 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
6271 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
6272 since GCC 4.4.6 issues a bogus warning for them.
6274 Fix bugs in file timestamp newness comparisons.
6275 * fileio.c (Ffile_newer_than_file_p):
6276 * lread.c (Fload): Use full timestamp resolution of files,
6277 not just the 1-second resolution, so that files that are only
6278 slightly newer still count as newer.
6279 * fileio.c (Ffile_newer_than_file_p): Don't assume file
6280 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
6282 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
6284 * fileio.c: Improve handling of file time marker. (Bug#11852)
6285 (special_mtime): New function.
6286 (Finsert_file_contents, Fverify_visited_file_modtime):
6287 Use it to set special mtime values consistently.
6289 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
6291 * fileio.c (Finsert_file_contents): Properly handle st_mtime
6292 marker for non-existing file. (Bug#11852)
6294 2012-07-03 Glenn Morris <rgm@gnu.org>
6296 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
6297 and did not make it into globals.h).
6299 2012-07-03 Tom Tromey <tromey@redhat.com>
6301 * window.c (Fset_window_margins, Fset_window_fringes)
6302 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.

6345 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
6346 values which aren't power of 2.
6347 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
6348 Verify it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
6351 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
6353 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
6355 * alloc.c (mark_object): Revert part of last patch to use `switch'.
6357 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
6359 * alloc.c (allocate_vector_block): Remove redundant
6360 calls to mallopt if DOUG_LEA_MALLOC is defined.
6361 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
6362 avoid calls to mallopt if zero_vector is returned.
6364 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
6366 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
6367 is enabled, avoid dereferencing NULL current_sblock if
6370 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
6372 Cleanup basic buffer management.
6373 * buffer.h (struct buffer): Change layout to use generic vector
6374 marking code. Fix some comments. Change type of 'clip_changed'
6375 to bitfield. Remove unused #ifndef old.
6376 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
6377 (GET_OVERLAYS_AT): Fix indentation.
6378 (for_each_per_buffer_object_at): New macro.
6379 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
6380 (Fbuffer_local_variables): Use it.
6381 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
6382 * alloc.c (allocate_buffer): Adjust to match new layout of
6383 struct buffer. Fix comment.
6384 (mark_overlay): New function.
6385 (mark_buffer): Use it. Use mark_vectorlike to mark normal
6386 Lisp area of struct buffer.
6387 (mark_object): Use it. Adjust marking of misc objects
6388 and related comments.
6390 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
6392 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
6393 wrapper that is not needed because the wrapped code is a no-op (zero
6394 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
6395 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
6397 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
6399 * alloc.c (mark_buffer): Simplify. Remove prototype.
6400 (mark_object): Add comment. Reorganize marking of vector-like
6401 objects. Use CHECK_LIVE for all vector-like objects except buffers
6402 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
6403 Avoid redundant calls to mark_vectorlike for bool vectors.
6405 2012-06-30 Glenn Morris <rgm@gnu.org>
6407 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
6409 * epaths.in (PATH_SITELOADSEARCH): New.
6410 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
6411 This is rather than relying on --enable-locallisppath elements
6412 having "site-lisp" in their names. (Bug#10208#25, 11658)
6414 2012-06-30 Eli Zaretskii <eliz@gnu.org>
6416 * w32proc.c (sys_select): Accept and ignore one more argument.
6418 * w32.c (emacs_gnutls_pull): Call select with one more argument.
6420 * sysselect.h [DOS_NT]: Don't include sys/select.h.
6421 (pselect) [!MS_DOS]: Redirect to sys_select.
6423 * sysdep.c: Don't include dos.h and dosfns.h.
6425 * process.c (sys_select):
6426 * msdos.c (sys_select): Accept one more argument and ignore it.
6428 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
6429 adapt data types and code to that.
6432 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
6433 which clashes with the gnulib function of the same name.
6435 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
6437 * font.c (font_style_to_value, font_style_symbolic)
6438 (font_prop_validate_style): Add type checks for values in
6441 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
6443 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
6446 2012-06-29 Eli Zaretskii <eliz@gnu.org>
6448 * xdisp.c (try_window_id): Undo last change.
6450 * w32.c (getwd): Adjust commentary about startup_dir.
6451 (init_environment): Always call sys_access, even in non-MSVC
6452 builds. Don't chdir to the directory of the Emacs executable.
6453 This undoes code from 1997 which was justified by the need to
6454 "avoid conflicts when removing and renaming directories". But its
6455 downside was that every relative file name was being interpreted
6456 relative to the directory of the Emacs executable, which can never
6457 be TRT. In particular, it broke sys_access when called with
6458 relative file names.
6459 (sys_access): Map GetLastError to errno.
6461 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
6463 * window.h (struct window): Change type of 'fringes_outside_margins'
6464 to bitfield. Fix comment. Adjust users accordingly.

6467 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
6470 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>

6473 Add QUIT to make the loop interruptible.
6475 2012-06-29 Glenn Morris <rgm@gnu.org>
6477 * charset.c (init_charset): Make lack of etc/charsets fatal.
6479 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
6481 * editfns.c (region_limit): Fix type mismatch.
6483 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
6485 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
6486 undefined. Convert from xassert to eassert.
6487 * nsmenu.m: Convert from xassert to eassert.
6488 * nsterm.m: Likewise.
6490 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
6492 * editfns.c (region_limit): Clip to narrowing (bug#11770).
6494 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
6496 Avoid integer overflow on scroll-left and scroll-right.
6497 * window.c (HSCROLL_MAX): New macro.
6498 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
6499 overflow when requested scroll falls outside ptrdiff_t range.
6501 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
6503 * window.h (struct window): Change type of 'hscroll',
6504 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
6505 'last_modified' and 'last_overlay_modified' to EMACS_INT.
6506 Adjust users accordingly.
6507 * xdisp.c (try_cursor_movement): Replace type check with eassert.
6508 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
6509 from EMACS_INT to ptrdiff_t.
6510 (make_window): Omit redundant initialization.
6512 2012-06-28 Juanma Barranquero <lekktu@gmail.com>

6516 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
6518 * window.h (struct window): Change type of 'use_time' and

6585 * alloc.c (allocate_string): Omit intervals initialization.
6586 * alloc.c (make_uninit_multibyte_string): Initialize intervals

6643 * alloc.c: Remove build_string.
6644 * lisp.h: Define build_string as static inline. This provides
6645 a better opportunity to optimize away calls to strlen when the
6646 function is called with compile-time constant argument.
6647 * image.c (imagemagick_error): Convert to build_string.
6648 * w32proc.c (sys_spawnve): Likewise.

6651 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
6653 Use sprintf return value instead of invoking strlen on result.
6654 In the old days this wasn't portable, since some sprintf
6655 implementations returned char *. But they died out years ago and
6656 Emacs already assumes sprintf returns int.
6657 Similarly for float_to_string.
6658 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
6659 * ccl.c (ccl_driver):
6660 * character.c (string_escape_byte8):

6665 * xfns.c (syms_of_xfns):
6666 Use sprintf or float_to_string result to avoid need to call strlen.
6667 * data.c (Fnumber_to_string):
6668 Use make_unibyte_string, since the string must be ASCII.
6669 * lisp.h, print.c (float_to_string): Now returns int length.
6670 * term.c (produce_glyphless_glyph):
6671 Use sprintf result rather than recomputing it.
6673 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
6674 * Makefile.in (ALL_CFLAGS):
6675 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

6704 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
6706 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
6707 `const char *' to `char *' to avoid compiler warning.
6709 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
6711 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
6712 instead of truncating it to 63 (admittedly a generous limit).
6714 * process.c: Fix spelling and caps in comments.
6716 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
6718 * emacs.c (setpgrp): Remove definition, unused.

6765 Remove unnecessary forward decls.
6767 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
6769 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).

6771 * dispnew.c (Fsleep_for, sit_for):
6772 * keyboard.c (kbd_buffer_get_event):
6773 * process.c (Faccept_process_output):
6774 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
6775 This improves on the previous patch, which introduced a bug

6842 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
6844 Support higher-resolution time stamps (Bug#9000).
6845 The time stamps are only nanosecond-resolution at the C level,
6846 since that's the best that any real-world system supports now.
6847 But they are picosecond-resolution at the Lisp level, as that's
6848 easy, and leaves room for future OS improvements.
6850 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
6853 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
6854 Don't get current time unless it's needed.
6856 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
6857 now provides it if it's absent.
6858 (start_atimer): Port to higher-res time stamps.
6859 Check for time stamp overflow. Don't get current time more
6860 often than is needed.
6862 * buffer.h (struct buffer): Buffer modtime now has high resolution.
6863 Include systime.h, not time.h.
6864 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
6866 * dired.c: Include stat-time.h.
6867 (Ffile-attributes): File times now have higher resolution.

6870 (struct image): Timestamp now has higher resolution.
6872 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
6873 has at least microseconds now. All uses removed.
6874 (update_frame, update_single_window, update_window, update_frame_1)
6875 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
6876 (duration_to_sec_usec): Remove; no longer needed.

6884 (decode_time_components, lisp_seconds_argument): New functions.
6885 (make_time): Now static.
6886 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
6887 Report an error if the time is invalid, rather than having the caller
6890 * fileio.c: Include <stat-time.h>
6891 (Fcopy_file): Copy higher-resolution time stamps.
6892 Prefer to set the time stamp via a file descriptor if that works.

6894 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
6895 (Fvisited_file_modtime, Fset_visited_file_modtime):
6896 Support higher-resolution time stamps.
6898 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
6900 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
6902 * image.c (prepare_image_for_display, clear_image_cache)
6903 (lookup_image): Port to higer-resolution time stamps.
6905 * keyboard.c (start_polling, bind_polling_period):
6906 Check for time stamp overflow.
6907 (read_char, kbd_buffer_get_event, timer_start_idle)
6908 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
6909 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
6910 Port to higher-resolution time stamps. Do not assume time_t is signed.
6911 (decode_timer): New function. Timers are now vectors of length 9,
6912 not 8, to accommodate the picosecond component.
6913 (timer_check_2): Use it.
6915 * nsterm.m (select_timeout, timeval_subtract): Remove.
6916 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
6917 as they're a bit more accurate and handle overflow better.
6918 (ns_select): Change prototype to be compatible with pselect.
6919 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
6920 * nsterm.h (ns_select): Adjust prototype.
6922 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
6923 us-resolution time stamps.
6924 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
6926 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
6928 * lisp.h (time_overflow): New decl.
6929 (wait_reading_process_output): First arg is now intmax_t, not int,
6930 to accommodate larger waits.
6932 * process.h (struct Lisp_Process.read_output_delay):
6933 Now counts nanoseconds, not microseconds.
6934 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
6936 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
6937 (wait_reading_process_output):
6938 Port to ns-resolution time stamps.
6939 (Faccept_process_output, wait_reading_process_output):
6940 Check for time stamp overflow. Do not assume time_t is signed.
6941 (select_wrapper): Remove; we now use pselect.
6942 (Fprocess_attributes): Now generates ns-resolution time stamps.
6944 * sysdep.c: Include utimens.h. Don't include utime.h
6945 or worry about struct utimbuf; gnulib does that for us now.
6946 (gettimeofday): Remove; gnulib provides a substitute.
6947 (make_timeval): New function.
6948 (set_file_times): Now sets ns-resolution time stamps.
6949 New arg FD; all uses changed.
6950 (time_from_jiffies, ltime_from_jiffies, get_up_time)
6951 (system_process_attributes):
6952 Now returns ns-resolution time stamp. All uses changed.
6953 Check for time stamp overflow.
6955 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
6956 provides a substitute now.
6958 * systime.h: Include timespec.h rather than sys/time.h and time.h,
6959 since it guarantees struct timespec.
6960 (EMACS_TIME): Now struct timespec, so that we can support
6961 ns-resolution time stamps.
6962 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
6963 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
6964 (EMACS_USECS): Remove.
6965 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
6966 so multiply the arg by 1000 before storing it.
6967 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
6969 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
6970 Port to ns-resolution time stamps.
6971 (EMACS_TIME_NEG_P): Remove; replaced by....
6972 (EMACS_TIME_SIGN): New macro.
6973 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
6974 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
6975 (set_file_times, make_time, lisp_time_argument): Adjust signature.
6976 (make_timeval, make_lisp_time, decode_time_components): New decls.
6977 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
6978 that it mishandled time_t overflow. You can't compare by subtracting!
6979 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
6980 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
6982 * term.c: Include <sys/time.h>.
6983 (timeval_to_Time): New function, for proper overflow wraparound.

6988 (Fprimitive_undo): Use them when restoring time stamps.
6990 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
6991 (w32_get_internal_run_time):
6992 Port to higher-resolution Emacs time stamps.
6993 (ltime): Now accepts single 64-bit integer, as that's more convenient
6996 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
6998 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
6999 for compatibility with pselect. Support ns-resolution time stamps.
7001 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
7003 * xselect.c (wait_for_property_change, x_get_foreign_selection):
7004 Check for time stamp overflow, and support ns-resolution time stamps.
7006 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
7007 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
7008 (timeval_subtract): Remove; no longer needed.
7009 (XTflash, XTring_bell, x_wait_for_event):
7010 Port to ns-resolution time stamps. Don't assume time_t is signed.
7012 2012-06-22 Chong Yidong <cyd@gnu.org>

7016 2012-06-22 Eli Zaretskii <eliz@gnu.org>
7018 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
7019 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
7020 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
7021 staticidx goes up to 1597 out of 1600 = 0x640.)
7023 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
7025 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
7026 Otherwise, the umask might be mistakenly 0 while handling input signals.

7060 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
7061 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
7062 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.

7071 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
7072 gets killed during executing of this function (Bug#11665).
7073 Try to always return Qt when the buffer has been actually killed.
7074 (Vkill_buffer_query_functions): In doc-string say that functions
7075 run by this hook should not change the current buffer.
7077 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

7097 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
7099 * lisp.h (eassert): Assume C89 or later.
7100 This removes the need for CHECK.
7101 (CHECK): Remove. Its comments about always evaluating its
7102 argument were confusing, as 'eassert' typically does not evaluate
7105 * coding.c (produce_chars): Use ptrdiff_t, not int.
7107 * xterm.c (x_draw_underwave): Check for integer overflow.
7108 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

7254 (XHASH, XTYPE, XINT, XUINT, make_number, XSET, XPNTR, XUNTAG):
7256 * emacs.c (gdb_use_struct): Rename from gdb_use_union.
7257 * .gdbinit: Check gdb_use_struct instead of gdb_use_union.
7258 * alloc.c (widen_to_Lisp_Object): Remove.
7259 (mark_memory): Use XIL instead of widen_to_Lisp_Object.
7260 * frame.c (delete_frame): Remove outdated comment.
7261 * w32fns.c (Fw32_register_hot_key): Use XLI instead of checking
7262 USE_LISP_UNION_TYPE.
7263 (Fw32_unregister_hot_key): Likewise.
7264 (Fw32_toggle_lock_key): Likewise.
7265 * w32menu.c (add_menu_item): Likewise.
7266 (w32_menu_display_help): Use XIL instead of checking
7267 USE_LISP_UNION_TYPE.
7268 * w32heap.c (allocate_heap): Don't check USE_LISP_UNION_TYPE.
7269 (init_heap): Likewise.
7270 * w32term.c (w32_read_socket): Update comment.

7277 * s/gnu.h (POSIX_SIGNALS): Remove (not used since 2010-05-04).
7279 2012-06-13 Paul Eggert <eggert@cs.ucla.edu>
7281 USE_LISP_UNION_TYPE + USE_LSB_TAG cleanup (Bug#11604)
7282 * alloc.c (make_number) [!defined make_number]:
7283 Remove, as lisp.h always defines this now.
7284 (mark_maybe_pointer): Simplify since USE_LSB_TAG is always defined now.
7285 (roundup_size): Verify that it is a power of 2.
7286 * data.c (Fmake_variable_buffer_local, Fmake_local_variable):
7287 * ftfont.c (ftfont_driver): Use LISP_INITIALLY_ZERO.
7288 * lisp.h (USE_LSB_TAG): Allow the builder to compile with
7289 -DUSE_LSB_TAG=0, to override the automatically-selected default.
7290 USE_LSB_TAG now is always defined to be either 0 or 1.
7292 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
7293 code works fine either way, and efficiency is not a concern here,
7294 as the union type is for debugging, not for production.
7295 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
7296 Use an inline function on all platforms when using the union type,
7297 since this is simpler and 'static inline' can be used portably
7299 (LISP_INITIALLY_ZERO): New macro.
7300 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
7301 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.

7318 MagickMergeImageLayers is undefined. Use pixel pusher loop if
7319 MagickExportImagePixels is undefined.

7328 * s/gnu-kfreebsd.h, s/gnu-linux.h, s/gnu.h, s/hpux10-20.h:
7329 * s/irix6-5.h, s/ms-w32.h, s/msdos.h, s/template.h:
7330 * s/usg5-4-common.h: Move SYSTEM_TYPE to configure.

7340 * image.c (imagemagick_load_image): Implement transparency.
7342 2012-06-10 Andreas Schwab <schwab@linux-m68k.org>

7369 * dbusbind.c (XD_BASIC_DBUS_TYPE): Use dbus_type_is_valid and
7370 dbus_type_is_basic if available.
7371 (xd_extract_signed, xd_extract_unsigned): Rename from
7372 extract_signed and extract_unsigned, respectively. Adapt callers.
7374 2012-06-09 Chong Yidong <cyd@gnu.org>

7383 * xdisp.c (vmessage): Treat frame message as multibyte.
7384 Without this change, (let ((§ 1)) (make-variable-buffer-local '§))
7385 would generate the diagnostic "Making \302\247 buffer-local while
7388 2012-06-08 Eli Zaretskii <eliz@gnu.org>
7390 * dispnew.c (showing_window_margins_p): Undo last change, which

7401 2012-06-08 Juanma Barranquero <lekktu@gmail.com>
7403 * dispnew.c (showing_window_margins_p): Wrap in #if 0 to prevent unused
7404 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
7406 2012-06-08 Eli Zaretskii <eliz@gnu.org>
7408 * alloc.c (allocate_vectorlike): Fix last change.
7410 2012-06-08 Dmitry Antipov <dmantipov@yandex.ru>
7412 Block-based vector allocation of small vectors.
7413 * lisp.h (struct vectorlike_header): New field `nbytes',
7414 adjust comment accordingly.
7415 * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'
7416 to denote vector blocks. Adjust users (live_vector_p,
7417 mark_maybe_pointer, valid_lisp_object_p) accordingly.

7437 * eval.c (Fmacroexpand): Stop if the macro returns the same form.
7439 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
7441 * doprnt.c (doprnt): Truncate multibyte char correctly.
7442 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
7443 would mishandle a string argument "Xc" if X was a multibyte
7444 character of length 2: it would truncate after X's first byte
7445 rather than including all of X.
7447 2012-06-06 Chong Yidong <cyd@gnu.org>
7449 * buffer.c (word_wrap): Doc fix.

7498 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
7499 Convert pctcpu and pctmem to Lisp float properly.
7500 Let the compiler fold better, as 100.0/0x8000 is exact.
7502 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
7504 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
7507 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
7509 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
7511 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
7513 For a 'struct window', replace some Lisp_Object fields to
7514 bitfields where appropriate, remove unused fields.
7515 * window.h (struct window): Remove unused 'last_mark_x' and
7516 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
7517 change it's type from Lisp_Object to bitfield.
7518 Change type of 'force_start', 'optional_new_start',
7519 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
7520 fields from Lisp_Object to bitfield. Adjust users accordingly.
7522 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
7524 Pacify gcc -Wdouble-precision when using Xaw.
7525 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
7526 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
7527 Use 'float' consistently, rather than 'float' in most places
7528 and 'double' in a couple of places.
7530 2012-05-31 Eli Zaretskii <eliz@gnu.org>
7532 * xdisp.c (handle_stop): Detect whether we have overlay strings
7533 loaded by testing it->current.overlay_string_index to be
7534 non-negative, instead of checking whether n_overlay_strings is
7535 positive. (Bug#11587)
7537 2012-05-31 Chong Yidong <cyd@gnu.org>
7539 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
7541 * doc.c (Fsubstitute_command_keys): Doc fix.
7543 2012-05-31 Eli Zaretskii <eliz@gnu.org>
7545 * search.c (search_buffer): Remove calls to
7546 r_alloc_inhibit_buffer_relocation, as it is now called by
7547 maybe_unify_char, which was the cause of relocation of buffer text
7550 2012-05-31 Eli Zaretskii <eliz@gnu.org>
7552 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
7553 for the duration of call to load_charset, to avoid problems with
7554 callers of maybe_unify_char that access buffer text through C
7557 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
7558 decrement the inhibition flag, instead of just setting or
7561 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
7563 Remove obsolete '#define static' cruft.
7564 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
7565 This #undef was "temporary" in 2000; it is no longer needed
7566 now that '#define static' has gone away.
7567 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
7568 (gray_bitmap_bits): Remove; no longer needed.
7569 All uses replaced with definiens.
7570 * xterm.c: Include "bitmaps/gray.xbm".
7572 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
7574 Clean up __executable_start, monstartup when --enable-profiling.
7575 The following changes affect the code only when profiling.
7576 * dispnew.c (__executable_start): Rename from safe_bcopy.
7577 Define only on platforms that need it.
7578 * emacs.c: Include <sys/gmon.h> when profiling.
7579 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
7580 (__executable_start): Remove decl, since lisp.h does it now.
7581 (safe_bcopy): Remove decl; no longer has that name.
7582 (main): Coalesce #if into single bit of code, for simplicity.
7583 Cast pointers to uintptr_t, since standard libraries want integers

7608 * lread.c (read1): Tiny simplification.
7610 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
7612 Do not create empty overlays with the evaporate property (Bug#9642).
7613 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
7614 Bug#9642, but explicitly check that the buffer the overlay would
7615 be moved to is live and rearrange lines to make sure that errors
7616 will not put the overlay in an inconsistent state.
7617 (Fdelete_overlay): Cosmetics.
7619 2012-05-28 Eli Zaretskii <eliz@gnu.org>
7621 * w32term.c (my_bring_window_to_top): New function.
7622 (x_raise_frame): Use handle returned by DeferWindowPos, which

7627 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
7628 by calling BringWindowToTop.

7633 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
7635 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
7636 This avoids undefined behavior that might cause the eassert
7637 to not catch an out-of-range value.
7639 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
7641 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

7653 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
7655 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
7656 Only r_alloc_inhibit_buffer_relocation needed to be added;
7657 the others were already declared.
7659 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
7660 before checking whether it's out of range. Put the check inside
7662 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
7664 2012-05-27 Ken Brown <kbrown@cornell.edu>
7666 * callproc.c (Fcall_process): Restore a line that was accidentally
7667 commented out in the 2011-02-13 change (bug#11547).

7671 * lisp.h [REL_ALLOC]: Add prototypes for external functions
7672 defined on ralloc.c.
7674 * buffer.c [REL_ALLOC]: Remove prototypes of
7675 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
7676 they are now on lisp.h.
7678 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
7680 * search.c (search_buffer): Use it to inhibit relocation of buffer
7681 text while re_search_2 is doing its job, because re_search_2 is
7682 passed C pointers to buffer text. (Bug#11519)
7684 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
7687 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
7688 state after an additional call to move_it_in_display_line_to, keep
7689 the values of it->max_ascent and it->max_descent found for the
7691 (pos_visible_p): Revert the comparison against bottom_y to what it
7692 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
7695 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
7697 Fix coding-related core dumps with gcc -ftrapv.
7698 The code was computing A - B, where A and B are pointers, and B is
7699 random garbage. This can lead to core dumps on platforms that
7700 have special pointer registers, and it also leads to core dumps on
7701 x86-64 when compiled with gcc -ftrapv. The fix is to compute
7702 A - B only when B is initialized properly.
7703 * coding.c (coding_set_source, coding_set_destination): Return void.
7704 (coding_change_source, coding_change_destinations): New functions,
7705 with the old behaviors of coding_set_source and coding_set_destination.
7706 All callers that need an offset changed to use these new functions.
7708 2012-05-26 Glenn Morris <rgm@gnu.org>
7710 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
7712 2012-05-26 Eli Zaretskii <eliz@gnu.org>
7714 Extend mouse support on W32 text-mode console.
7715 * xdisp.c (draw_row_with_mouse_face):
7716 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
7718 * w32console.c: Include window.h.
7719 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
7721 (initialize_w32_display): Initialize mouse-highlight data.
7723 * w32inevt.c: Include termchar.h and window.h.
7724 (do_mouse_event): Support mouse-autoselect-window. When the mouse

7732 * lread.c (read1): Simplify slightly to avoid an overflow warning
7733 with GCC 4.7.0 on x86-64.
7735 2012-05-26 Eli Zaretskii <eliz@gnu.org>
7737 * bidi.c (bidi_mirror_char): Revert last change: an int is
7738 definitely wide enough here.
7740 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
7742 Fix integer width and related bugs (Bug#9874).

7754 Use int, not EMACS_INT, where int is wide enough.

7774 (Foverlay_recenter, last_overlay_modification_hooks_used)
7775 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
7776 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
7777 (validate_region): Omit unnecessary test for b <= e,
7778 since that's guaranteed by the previous test.
7779 (adjust_overlays_for_delete): Avoid pos + length overflow.
7780 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
7781 (report_overlay_modification):
7782 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
7783 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):

7792 not int, to avoid needless 32-bit limit on 64-bit hosts.
7793 (exec_byte_code): Use tighter memory-full test, one that checks
7794 for alloca overflow. Don't compute the address of the object just
7795 before an array, as that's not portable. Use EMACS_INT, not
7796 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
7797 * callint.c (Fcall_interactively):
7798 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

7809 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
7810 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
7811 (casify_object): Avoid integer overflow when overallocating buffer.
7812 * casetab.c (set_identity, shuffle): Prefer int to unsigned when

7815 * category.h (CATEGORYP): Don't assume arg is nonnegative.
7816 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
7817 integers are now checked earlier. All uses replaced with XINT.
7819 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
7820 For CCL_MapSingle, check that content and value are in int range.
7821 (ccl_driver, Fregister_code_conversion_map):
7822 Check that Vcode_version_map_vector is a vector.
7823 (resolve_symbol_ccl_program): Check that vector header is in range.
7824 Always copy the vector, so that we can check its contents reliably
7825 now rather than having to recheck each instruction as it's being
7826 executed. Check that vector words fit in 'int'.
7827 (ccl_get_compiled_code, Fregister_ccl_program)
7828 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
7829 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
7830 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
7831 contents are in range.
7832 (Fccl_execute_on_string): Check that status is in range.
7833 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
7834 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
7835 Accept and return EMACS_INT, not int, because callers can pass values
7837 (c_string_width, strwidth, lisp_string_width, chars_in_text)
7838 (multibyte_chars_in_text, parse_str_as_multibyte)

7841 (string_escape_byte8, Fget_byte):
7842 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

7844 avoid mishandling large integers.
7845 * character.h: Adjust decls to match defn changes elsewhere.

7855 Don't rely on undefined behavior with signed left shift overflow.
7856 Don't assume unsigned int fits into fixnum, or that fixnum fits
7857 into unsigned int. Don't require max_code to be a valid fixnum;
7858 that's not true for gb10830 4-byte on a 32-bit host. Allow
7859 invalid_code to be a cons, for the same reason. Require code_offset
7860 to be a character. Avoid int overflow if max_char is close
7862 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
7863 this is intended anyway and avoids some undefined behavior.
7864 (load_charset_map): Pass unsigned, not int, as 2nd arg of
7865 INDEX_TO_CODE_POINT, as that's what it expects.
7866 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
7867 * charset.h (DECODE_CHAR): Return int, not unsigned;
7868 this is what was intended anyway, and it avoids undefined behavior.
7869 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
7870 integer-overflow issues.
7871 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
7872 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
7873 where the argument is EMACS_INT, and this behavior is not intended.
7874 * chartab.c (Fmake_char_table, Fset_char_table_range)
7875 (uniprop_get_decoder, uniprop_get_encoder):
7876 Don't assume fixnum fits in int.
7877 * cmds.c (move_point): New function, that does the gist of
7878 Fforward_char and Fbackward_char, but does so while checking
7879 for integer overflow more accurately.
7880 (Fforward_char, Fbackward_char): Use it.
7881 (Fforward_line, Fend_of_line, internal_self_insert)
7882 (internal_self_insert):
7883 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

8542 2012-05-25 Glenn Morris <rgm@gnu.org>
8544 * lisp.mk (lisp): Update for more files being compiled now.
8546 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>

8566 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
8569 This directory predates autoconf and is no longer needed nowadays.

8580 (EMACS_UINT): Define unconditionally now.
8581 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
8582 (BITS_PER_EMACS_INT): New constants, replacing
8583 what used to be in config.h, but not useful in #if.
8584 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
8585 define them any more.
8586 (VAL_MAX): New macro.
8588 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
8589 BITS_PER_EMACS_INT, in #if.
8590 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
8591 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
8592 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
8593 * s/ms-w32.h (DATA_START):
8594 Move here from removed file m/intel386.h.
8595 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
8596 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
8598 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
8600 Assume C89 or later.

8610 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
8611 * xterm.c (input_signal_count): Assume volatile works.
8613 2012-05-21 Ken Brown <kbrown@cornell.edu>
8615 * xgselect.c (xg_select): Fix first argument in call to 'select'
8618 2012-05-20 Ken Brown <kbrown@cornell.edu>
8620 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
8621 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.

8625 * xfns.c (x_in_use): Remove `static' qualifier.
8626 * xterm.h (x_in_use): Declare.
8627 * xgselect.c: Include xterm.h.

8633 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.

8636 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
8638 2012-05-18 Eli Zaretskii <eliz@gnu.org>
8640 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
8642 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
8643 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
8645 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
8646 reference to image_cache->refcount.
8647 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
8649 2012-05-17 Juri Linkov <juri@jurta.org>
8651 * search.c (Fword_search_regexp, Fword_search_backward)
8652 (Fword_search_forward, Fword_search_backward_lax)
8653 (Fword_search_forward_lax): Move functions to isearch.el
8654 (bug#10145, bug#11381).
8656 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
8658 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
8660 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
8662 * lread.c (init_obarray): Declare Qt and Qnil as special.
8664 2012-05-14 Glenn Morris <rgm@gnu.org>
8666 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
8667 Put "libexec" before "bin", for the sake of init_callproc_1.
8669 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
8671 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
8673 * unexaix.c: Port to more-recent AIX compilers.
8674 (report_error, report_error_1, make_hdr, copy_sym)
8675 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
8676 Make arguments const char *, not char *, to avoid violations of C
8677 standard and to fix some AIX warnings reported by Gilles Pion.
8679 2012-05-14 Eli Zaretskii <eliz@gnu.org>
8681 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
8682 already have overlays loaded.
8683 (handle_single_display_spec): Before returning without displaying
8684 fringe bitmap, synchronize the bidi iterator with the main display
8685 iterator, by calling iterate_out_of_display_property.
8686 (iterate_out_of_display_property): Detect buffer iteration by
8687 testing that it->string is a Lisp string.
8688 (get_next_display_element): When the current object is exhausted,
8689 and there's something on it->stack, call set_iterator_to_next to
8690 proceed with what's on the stack, instead of returning zero.
8691 (set_iterator_to_next): If called at the end of a Lisp string,
8692 proceed to consider_string_end without incrementing string
8693 position. Don't increment display vector index past the end of
8694 the display vector. (Bug#11417)
8695 (pos_visible_p): Don't report a position visible when move_it_to
8696 stopped at the last line of window, which happens to be scanned
8697 backwards by the bidi iteration. (Bug#11464)
8699 2012-05-14 Eli Zaretskii <eliz@gnu.org>
8701 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
8702 and right-margin display specs even if the spec is invalid or we
8703 are on a TTY, and thus unable to display on the fringes.
8704 That's because the text with the property will not be displayed anyway,
8705 so we need to signal to the caller that this is a "replacing"
8706 display spec. This fixes display when the spec is invalid or we
8709 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
8711 * unexaix.c (make_hdr): Fix typo in prototype.
8712 This bug broke the build on AIX. Problem reported by Gilles Pion.
8714 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
8716 * keyboard.c (kbd_buffer_get_event): Read special events also in
8717 batch mode. (Bug#11415)
8719 2012-05-12 Glenn Morris <rgm@gnu.org>
8721 * ns.mk: Update for ns_appbindir no longer having trailing "/".
8723 2012-05-12 Eli Zaretskii <eliz@gnu.org>
8725 * lisp.mk (lisp): Add newcomment.elc.
8727 2012-05-12 Glenn Morris <rgm@gnu.org>
8729 * Makefile.in (MKDIR_P): New, set by configure.
8730 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
8732 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
8734 Remove unused function hourglass_started.
8735 * dispextern.h (hourglass_started):
8736 * w32fns.c (hourglass_started):
8737 * xdisp.c (hourglass_started): Remove.
8739 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
8741 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
8742 Update dependencies.
8744 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
8746 * xgselect.c (xg_select): Put maxfds+1 into a var.
8747 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
8749 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
8751 2012-05-10 Dave Abrahams <dave@boostpro.com>
8753 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
8754 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
8756 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
8758 * dbusbind.c (xd_registered_buses): New internal Lisp object.
8759 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
8760 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
8761 Initialize xd_registered_buses.
8763 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
8765 Untag more efficiently if USE_LSB_TAG.
8766 This is based on a proposal by YAMAMOTO Mitsuharu in
8767 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
8768 For an admittedly artificial (nth 8000 longlist) benchmark on
8769 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
8770 Emacs's overall text size by 1%.
8771 * lisp.h (XUNTAG): New macro.
8772 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
8773 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
8774 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
8775 * eval.c (Fautoload):
8776 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
8777 * frame.h (XFRAME): Use XUNTAG.
8779 Port recent dbusbind.c changes to 32-bit --with-wide-int.
8780 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
8781 Remove unportable assumptions about print widths of types like
8783 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
8784 intptr_t when converting between pointer and integer, to avoid GCC
8785 warnings about wrong width.
8787 2012-05-09 Eli Zaretskii <eliz@gnu.org>
8789 * w32proc.c (new_child): Force Windows to reserve only 64KB of
8790 stack for each reader_thread, instead of defaulting to 8MB
8791 determined by the linker. This avoids failures in creating
8792 subprocesses on Windows 7, see the discussion in this thread:
8793 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
8795 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
8797 Fix up display of the *Minibuf-0* buffer in the mini window.
8798 * keyboard.c (read_char): Don't clear the echo area if there's no
8800 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
8801 contents of *Minibuf-0*) if there's no message displayed in its stead.
8803 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
8805 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
8808 2012-05-06 Chong Yidong <cyd@gnu.org>
8810 * lisp.mk (lisp): Update.
8812 2012-05-05 Jim Meyering <meyering@redhat.com>
8814 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
8816 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
8818 * data.c (PUT_ERROR): New macro.
8819 (syms_of_data): Use it. Add new error type `user-error'.
8820 * undo.c (user_error): New function.
8821 (Fprimitive_undo): Use it.
8822 * print.c (print_error_message): Adjust print style for `user-error'.
8823 * keyboard.c (user_error): New function.
8824 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
8826 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
8828 Do not limit current-time-string to years 1000..9999.
8829 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
8830 (Fcurrent_time_string): Support any year that is supported by the
8831 underlying localtime representation. Don't use asctime, as it
8832 has undefined behavior for years outside the range -999..9999.
8834 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
8836 Fix race conditions involving setenv, gmtime, localtime, asctime.
8837 Without this fix, interrupts could mess up code that uses these
8838 nonreentrant functions, since setting TZ invalidates existing
8839 tm_zone or tzname values, and since most of these functions return
8840 pointers to static storage.
8841 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
8842 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
8843 Grow the critical sections to include not just invoking
8844 localtime/gmtime, but also accessing these functions' results
8845 including their tm_zone values if any, and any related TZ setting.
8846 (format_time_string): Last arg is now struct tm *, not struct tm **,
8847 so that the struct tm is saved in the critical section.
8848 All callers changed. Simplify allocation of initial buffer, partly
8849 motivated by the fact that memory allocation needs to be outside
8850 the critical section.
8852 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
8854 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
8855 with RESET_INTERVAL.

8866 2012-05-02 Eli Zaretskii <eliz@gnu.org>
8868 * xdisp.c (pos_visible_p): If already at a newline from the
8869 display string before the 'while' loop, don't walk back the glyphs
8870 from it3.glyph_row. Solves assertion violation when the display
8871 string begins with a newline (egg.el). (Bug#11367)
8873 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
8875 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
8878 2012-05-01 Glenn Morris <rgm@gnu.org>
8880 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
8881 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
8882 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
8883 All were removed before 23.1.
8885 * dispnew.c: Remove HAVE_LIBNCURSES test;
8886 it is always true on relevant platforms.
8888 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
8889 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
8891 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.

8895 * .gdbinit (xpr): Remove checks for no longer existing misc types.
8896 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
8899 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
8901 Do not avoid creating empty evaporating overlays (Bug#9642).
8902 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
8903 That is, do not delete an evaporating overlay if it becomes
8904 empty after its bounds are adjusted to fit within its buffer.
8905 This fix caused other problems, and I'm reverting it until we get
8906 to the bottom of them.
8908 2012-04-27 Chong Yidong <cyd@gnu.org>
8910 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
8912 2012-04-27 Eli Zaretskii <eliz@gnu.org>
8914 * xdisp.c (pos_visible_p): If the window start position is beyond
8915 ZV, start the display from buffer beginning. Prevents assertion
8916 violation in init_iterator when the minibuffer window is scrolled
8919 * window.c (window_scroll_pixel_based): Likewise.
8921 2012-04-27 Chong Yidong <cyd@gnu.org>

8928 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
8930 2012-04-27 Eli Zaretskii <eliz@gnu.org>
8932 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
8933 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
8935 2012-04-26 Eli Zaretskii <eliz@gnu.org>
8937 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
8938 display element, check also the underlying string or buffer
8939 character. (Bug#11341)
8941 * w32menu.c: Include w32heap.h.
8942 (add_menu_item): If the call to AppendMenuW (via
8943 unicode_append_menu) fails, disable Unicode menus only if we are
8944 running on Windows 9X/Me.
8946 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
8948 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.

8951 2012-04-24 Martin Rudalics <rudalics@gmx.at>
8953 * keyboard.c (read_char): Don't wipe echo area for select window
8954 events: These might get delayed via `mouse-autoselect-window'

8959 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
8960 manipulation of :loaded-from data.
8962 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
8964 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
8965 now a cons (bug#11311).
8967 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
8969 Do not create empty overlays with the evaporate property (Bug#9642).
8970 * buffer.c (Fmove_overlay): Delete an evaporating overlay
8971 if it becomes empty after its bounds are adjusted to fit within
8972 its buffer. Without this fix, in a nonempty buffer (let ((o
8973 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
8974 yields an empty overlay that has the evaporate property, which is
8975 not supposed to happen.
8977 Fix minor GTK3 problems found by static checking.
8978 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
8979 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
8980 (struct _EmacsFixedClass, emacs_fixed_get_type):

8993 Problem reported by Juanma Barranquero for Windows -Wunused-function.
8995 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
8997 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
8998 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
8999 (__malloc_size_t, __malloc_ptrdiff_t):
9000 Remove. All uses removed, replaced by the definiens if needed,

9012 Define using prototypes, not old style.
9013 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
9014 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.

9083 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

9092 * sysdep.c [__FreeBSD__]: Minor cleanups.
9093 (list_system_processes, system_process_attributes) [__FreeBSD__]:
9094 Use Emacs indenting style more consistently. Avoid some casts.
9095 Use 'double' consistently rather than mixing 'float' and 'double'.
9097 2012-04-21 Eduard Wiebe <usenet@pusto.de>
9099 * sysdep.c (list_system_processes, system_process_attributes):

9115 (print_object): Check for cycles even when print-circle is nil and
9116 print-gensym is t, but only check print_depth if print-circle is nil.
9118 2012-04-20 Chong Yidong <cyd@gnu.org>
9120 * process.c (wait_reading_process_output): If EIO occurs on a pty,
9121 set the status to "failed" and ensure that sentinel is run.

9178 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
9179 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.

9181 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
9182 Remove one incorrect comment and fix another.

9196 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
9197 Remove decls. This fixes an "It stinks!".
9199 * alloc.c (which_symbols): Fix alignment issue / type clash.
9201 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
9203 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

9251 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
9252 against is gone. It's better to use vfork now so that when Cygwin
9253 gains a new, working vfork, we use it automatically (bug#10398).
9255 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

9308 * minibuf.c (Fread_variable): Callers changed.
9310 2012-04-09 Eli Zaretskii <eliz@gnu.org>
9312 * xdisp.c (set_cursor_from_row): If the display string appears in
9313 the buffer at position that is closer to point than the position
9314 after the display string, display the cursor on the first glyph of
9315 the display string. Fixes cursor display when a 'display' text
9316 property immediately follows invisible text. (Bug#11094)
9318 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
9320 composite.c: use 'double' consistently
9321 * composite.c (get_composition_id): Use 'double' consistently
9322 instead of converting 'float' to 'double' and vice versa; this is
9323 easier to understand and avoids a GCC warning.
9325 2012-04-09 Glenn Morris <rgm@gnu.org>
9327 * Makefile.in: Generate leim-list with bootstrap-emacs, in
9328 preparation for dumping it with emacs. (Bug#4789)
9329 (leimdir): New variable.
9330 ($(leimdir)/leim-list.el): New rule.

9347 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
9349 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
9350 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
9351 (mark_memory): Mark Lisp_Objects only if pointers might hide in
9352 objects, as mark_maybe_pointer will catch them otherwise.
9353 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
9354 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
9356 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
9358 Fix typo that broke non-Windows builds.
9359 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.

9365 * makefile.w32-in (OBJ2): Add xml.$(O).
9366 (GLOBAL_SOURCES): Add xml.c.
9367 ($(BLD)/xml.$(O)): New dependency list.
9369 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
9370 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
9371 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
9372 [!WINDOWSNT]: New macros.
9373 (init_libxml2_functions, libxml2_loaded_p): New functions.
9374 (parse_region): Call fn_xmlCheckVersion instead of using the macro
9375 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
9376 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
9377 Calls xmlCleanupParser only if libxml2 was loaded (or statically
9379 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
9380 Call init_libxml2_functions before calling libxml2 functions.
9381 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
9383 * emacs.c: Don't include libxml/parser.h.
9384 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
9385 xmlCleanupParser directly.
9387 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
9389 2012-04-07 Eli Zaretskii <eliz@gnu.org>
9391 * indent.c (Fvertical_motion): If there is a display string at
9392 point, use it.vpos to compute how many lines to backtrack after
9393 move_it_to point. (Bug#11133)
9395 2012-04-06 Eli Zaretskii <eliz@gnu.org>
9397 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
9398 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
9399 about subtle differences between FETCH_CHAR* and STRING_CHAR*
9400 macros related to unification of CJK characters. For the details,
9401 see the discussion following the message here:
9402 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
9404 2012-04-04 Chong Yidong <cyd@gnu.org>
9406 * keyboard.c (Vdelayed_warnings_list): Doc fix.
9408 2012-04-01 Eli Zaretskii <eliz@gnu.org>
9410 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
9411 instead of alloca. (Bug#11138)
9413 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
9415 * w32menu.c (is_simple_dialog): Properly check lisp types.
9418 2012-03-31 Eli Zaretskii <eliz@gnu.org>
9420 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
9421 position we get to after a call to move_it_to fails the
9422 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
9423 only if we wind up in a string from display property. (Bug#11063)
9425 * window.c (Fdelete_other_windows_internal): Invalidate the row
9426 and column information about mouse highlight, so that redisplay
9427 restores it after reallocating the glyph matrices. (Bug#7464)
9429 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
9430 string comes from a `display' text property, use the buffer
9431 position of that property as if we actually saw that position in
9433 (move_it_by_lines): Remove the assertion that
9434 "it->current_x == 0 && it->hpos == 0" which can be legitimately
9435 violated when there's a before-string at the beginning of a line.
9438 2012-03-30 Eli Zaretskii <eliz@gnu.org>
9440 * xdisp.c (append_space_for_newline): If the default face was
9441 remapped, use the remapped face for the appended newline.
9442 (extend_face_to_end_of_line): Use the remapped default face for
9443 extending the face to the end of the line.
9444 (display_line): Call extend_face_to_end_of_line when the default
9445 face was remapped. (Bug#11068)
9447 2012-03-29 Eli Zaretskii <eliz@gnu.org>
9449 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
9451 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
9453 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
9455 2012-03-27 Glenn Morris <rgm@gnu.org>
9457 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
9460 2012-03-26 Kenichi Handa <handa@m17n.org>
9462 * dispextern.h (struct glyph): Fix previous change. Change the
9463 bit length of glyphless.ch to 25 (Bug#11082).
9465 2012-03-26 Chong Yidong <cyd@gnu.org>
9467 * keyboard.c (Vselection_inhibit_update_commands): New variable.
9468 (command_loop_1): Use it; inhibit selection update for
9469 handle-select-window too (Bug#8996).
9471 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
9473 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
9475 2012-03-25 Kenichi Handa <handa@m17n.org>
9477 * dispextern.h (struct glyph): Change the bit length of
9478 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
9480 2012-03-24 Eli Zaretskii <eliz@gnu.org>
9482 * s/ms-w32.h (tzname): Include time.h before redirecting to
9483 _tzname. Fixes the MSVC build. (Bug#9960)
9485 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
9487 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
9490 * xterm.c (XTread_socket): Only modify handling_signal if
9491 !SYNC_INPUT. (Bug#11080)
9493 2012-03-23 Eli Zaretskii <eliz@gnu.org>
9495 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
9496 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
9497 when fetching a multibyte character consumes more bytes than
9498 CHAR_BYTES returns, due to unification of CJK characters in
9499 string_char. (Bug#11073)
9501 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
9503 * process.c (wait_reading_process_output): Handle pty disconnect
9504 by refraining from sending oneself a SIGCHLD (bug#10933).
9506 2012-03-22 Chong Yidong <cyd@gnu.org>
9508 * dispextern.h (struct it): New member string_from_prefix_prop_p.
9510 * xdisp.c (push_prefix_prop): Rename from push_display_prop.

9519 2012-03-20 Eli Zaretskii <eliz@gnu.org>
9521 * w32proc.c (Fw32_set_console_codepage)
9522 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
9525 2012-03-20 Chong Yidong <cyd@gnu.org>
9527 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
9528 to reflect default non-nil value of redisplay-dont-pause.
9530 2012-03-19 Kenichi Handa <handa@m17n.org>
9532 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
9533 it fit in a valid range (Bug#11003).
9535 2012-03-18 Eli Zaretskii <eliz@gnu.org>
9537 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
9538 that is not from display property, accept the row as a "cursor
9539 row" if one of the string's character has a non-nil `cursor'
9540 property. Fixes cursor positioning when there are newlines in
9541 overlay strings, e.g. in icomplete.el. (Bug#11035)
9543 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
9545 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
9547 2012-03-12 Chong Yidong <cyd@gnu.org>
9549 * eval.c (inhibit_lisp_code): Rename from
9550 inhibit_window_configuration_change_hook; move from window.c.
9552 * xfns.c (unwind_create_frame_1, Fx_create_frame):
9553 * window.c (run_window_configuration_change_hook)
9554 (syms_of_window): Callers changed.
9556 2012-03-11 Chong Yidong <cyd@gnu.org>

9569 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
9571 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
9573 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
9574 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
9577 2012-03-03 Glenn Morris <rgm@gnu.org>
9579 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
9581 2012-03-02 Eli Zaretskii <eliz@gnu.org>
9583 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
9584 position past the first glyph_row that ends at ZV. (Bug#10902)
9585 (redisplay_window, next_element_from_string): Fix typos in
9587 (redisplay_window): Pass to move_it_vertically the margin in
9588 pixels, not in screen lines.
9590 2012-03-02 Glenn Morris <rgm@gnu.org>
9592 * buffer.c (buffer-list-update-hook): Doc fix.
9594 2012-02-29 Eli Zaretskii <eliz@gnu.org>
9596 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
9597 push_it before setting up the iterator for the first overlay
9598 string, even if we have an empty string loaded.
9599 (next_overlay_string): If there's an empty string on the iterator
9600 stack, pop the stack. (Bug#10903)
9602 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
9604 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
9605 Suggested by Stefan Monnier in
9606 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
9607 * alloc.c (widen_to_Lisp_Object): New static function.
9608 (mark_memory): Also mark Lisp_Objects by fetching pointer words
9609 and widening them to Lisp_Objects. This would work even if
9610 USE_LSB_TAG is defined and wide integers are used, which might
9611 happen in a future version of Emacs.
9613 2012-02-25 Chong Yidong <cyd@gnu.org>
9615 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
9618 * xselect.c (Fx_selection_exists_p): Doc fix.
9619 (x_clipboard_manager_save_all): Print an informative message
9620 before saving to clipboard manager.
9622 2012-02-24 Chong Yidong <cyd@gnu.org>
9624 * keyboard.c (process_special_events): Handle all X selection
9625 requests in kbd_buffer, not just the next one (Bug#8869).
9627 2012-02-23 Chong Yidong <cyd@gnu.org>

9630 call when setting menu-bar-lines and tool-bar-lines parameters.
9631 (unwind_create_frame_1): New helper function.
9633 * window.c (inhibit_window_configuration_change_hook): New var.
9634 (run_window_configuration_change_hook): Obey it.
9635 (syms_of_window): Initialize it.
9637 2012-02-22 Chong Yidong <cyd@gnu.org>

9652 when computing $valmask.
9654 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
9655 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
9656 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
9657 It's useless in that case, and it can cause problems on hosts
9658 that allocate halves of EMACS_INT values separately.
9659 Reported by Dan Horák. Diagnosed by Andreas Schwab in
9660 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
9661 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
9662 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
9663 it avoids undefined behavior on hosts where shifting right by more
9664 than the word width has undefined behavior.
9666 2012-02-19 Chong Yidong <cyd@gnu.org>
9668 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
9669 (Funhandled_file_name_directory, Ffile_name_as_directory)

9672 return values (Bug#10845).
9674 2012-02-18 Eli Zaretskii <eliz@gnu.org>
9676 * .gdbinit (pitx): Fix incorrect references to fields of the
9679 2012-02-17 Chong Yidong <cyd@gnu.org>

9686 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
9688 2012-02-15 Chong Yidong <cyd@gnu.org>
9690 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
9691 marked as special. Also, starting docstrings with * is obsolete.
9693 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>

9706 2012-02-12 Chong Yidong <cyd@gnu.org>
9708 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
9709 as that creates a dangerous corner case.
9711 * window.c (Fdelete_window_internal): Invalidate the mouse
9712 highlight (Bug#9904).
9714 2012-02-12 Glenn Morris <rgm@gnu.org>
9716 * xselect.c (Fx_own_selection_internal)
9717 (Fx_get_selection_internal, Fx_disown_selection_internal)
9718 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
9719 * nsselect.m (Fx_own_selection_internal)
9720 (Fx_disown_selection_internal, Fx_selection_exists_p)
9721 (Fx_selection_owner_p, Fx_get_selection_internal):
9722 Sync docs and argument specs with the xselect.c versions.
9724 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>

9744 2012-02-07 Chong Yidong <cyd@gnu.org>
9746 * buffer.c (Fbuffer_local_variables)
9747 (buffer_lisp_local_variables): Handle unbound vars correctly;
9748 don't let Qunbound leak into Lisp.
9750 2012-02-07 Glenn Morris <rgm@gnu.org>
9752 * image.c (Fimagemagick_types): Doc fix.
9754 * image.c (imagemagick-render-type): Change it from a lisp object
9755 to an integer. Move the doc here from the lisp manual.

9758 2012-02-06 Chong Yidong <cyd@gnu.org>
9760 * doc.c (store_function_docstring): Avoid applying docstring of
9761 alias to base function (Bug#2603).

9779 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
9780 after rounding frame sizes. (Bug#9723)
9782 2012-02-04 Eli Zaretskii <eliz@gnu.org>
9784 * keyboard.c (adjust_point_for_property): Don't position point
9785 before BEGV. (Bug#10696)
9787 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
9789 Handle overflow when computing char display width (Bug#9496).
9790 * character.c (char_width): Return EMACS_INT, not int.
9791 (char_width, c_string_width): Check for overflow when
9792 computing the width; this is possible now that individual
9793 characters can have unbounded width. Problem introduced
9794 by merge from Emacs 23 on 2012-01-19.
9796 2012-02-02 Michael Albinus <michael.albinus@gmx.de>
9798 * dbusbind.c (Fdbus_register_method): Mention the return value

10329 (ALIGN_GCTYPEBITS) [_MSC_VER]: Define.
10330 (DECL_ALIGN) [_MSC_VER]: Use it, as MSVC doesn't like bit ops in
10331 this macro definition.
10333 * s/ms-w32.h (tzname): Redirect to _tzname for all values of
10336 2011-11-27 Jan Djärv <jan.h.d@swipnet.se>

10358 * xdisp.c (redisplay_window): If cursor row is not fully visible
10359 after recentering, and scroll-conservatively is set to a large
10360 number, scroll window by a few more lines to make the cursor fully
10361 visible and out of scroll-margin. (Bug#10105)
10362 (start_display): Don't move to the next line if the display should
10363 start at a newline that is part of a display vector or an overlay
10364 string. (Bug#10119)
10366 2011-11-24 Juri Linkov <juri@jurta.org>

10443 Standardize on VIRT_ADDR_VARIES behavior (Bug#10042).
10444 Otherwise, valgrind does not work on some platforms.
10445 Problem reported by Andreas Schwab in
10446 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
10447 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
10448 is set, removing the need for VIRT_ADDRESS_VARIES.
10449 (PURE_P): Use a more-efficient implementation that needs just one
10450 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
10451 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
10452 to 4 (xorl, subq, cmpq, setbe).
10453 * alloc.c (pure): Always extern now, since that's the
10454 VIRT_ADDR_VARIES behavior.
10455 (PURE_POINTER_P): Use a single comparison, not two, for
10456 consistency with the new puresize.h.
10457 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
10458 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:
10459 Remove VIRT_ADDR_VARIES no longer needed.

10464 (erase_phys_cursor, update_window_cursor, show_mouse_face)
10465 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
10466 behave as if the cursor position were at the window margin.
10468 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
10469 and the cursor position is out of bounds, behave as if the cursor
10470 position were at the window margin. (Bug#10075)
10472 2011-11-18 Chong Yidong <cyd@gnu.org>
10474 * window.c (Fwindow_combination_limit): Make first argument
10475 non-optional, since it is meaningless for live windows like the

10489 * dispnew.c (swap_glyph_pointers): Swap the used[] arrays and the
10490 hash values of the two rows.
10491 (copy_row_except_pointers): Preserve the used[] arrays and the
10492 hash values of the two rows. (Bug#10035)
10493 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
10495 * xdisp.c (row_hash): New function, body extracted from
10496 compute_line_metrics.
10497 (compute_line_metrics): Call row_hash, instead of computing the
10500 * dispnew.c (verify_row_hash): Call row_hash for computing the
10501 hash code of a row, instead of duplicating code from xdisp.c.
10503 * dispextern.h (row_hash): Add prototype.
10505 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
10507 * frame.c (delete_frame): Don't delete the terminal when the last

10532 (recombine_windows, make_parent_window, make_window)
10533 (Fsplit_window_internal, saved_window)
10534 (Fset_window_configuration, save_window_save): Rename all
10535 occurrences of window_nest to window_combination_limit.
10537 2011-11-15 Juanma Barranquero <lekktu@gmail.com>
10539 * image.c (imagemagick_load_image): Fix typo.
10541 2011-11-14 Eli Zaretskii <eliz@gnu.org>
10543 * xdisp.c (display_line): Move the call to
10544 highlight_trailing_whitespace before the call to
10545 compute_line_metrics, since the latter needs to see the final
10546 faces of all the glyphs to compute ROW's hash value.
10547 Fixes assertion violations in row_equal_p. (Bug#10035)
10549 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
10551 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,
10552 just return (bug#10044).
10554 2011-11-12 Eli Zaretskii <eliz@gnu.org>
10556 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
10557 with user-defined heap size. Bump the default size of the temacs
10558 heap to 27MB, to avoid memory warning when running temacs.
10559 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
10561 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
10562 current_matrix and desired_matrix. (Bug#9990)
10563 (verify_row_hash) [XASSERTS]: New function.
10564 (adjust_glyph_matrix, row_equal_p): Use it in xassert to verify
10565 that the hash value of glyph rows is correct.

10597 avoid a crash (bug#9496).
10599 2011-11-09 Chong Yidong <cyd@gnu.org>
10601 * window.c (Fwindow_inside_edges, Fwindow_inside_pixel_edges)

10608 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
10610 Avoid some portability problems by eschewing 'extern inline' functions.
10611 The trivial performance wins aren't worth the portability hassles; see
10612 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
10614 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
10615 (window_box_width, window_box_left, window_box_left_offset)
10616 (window_box_right, window_box_right_offset): Undo previous change,
10617 by removing the "extern"s.
10618 * intervals.c (adjust_intervals_for_insertion)
10619 (adjust_intervals_for_deletion): Undo previous change,
10620 making these static again.
10621 (offset_intervals, temp_set_point_both, temp_set_point)
10622 (copy_intervals_to_string): No longer inline.
10623 * xdisp.c (window_text_bottom_y, window_box_width)

10663 This is also needed for porting to any host where GC_MARK_STACK is
10664 not GC_MAKE_GCPROS_NOOPS.
10665 (which_symbols): Use it.
10667 2011-11-07 Kenichi Handa <handa@m17n.org>

10680 * xmenu.c (cleanup_widget_value_tree): New function.
10681 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
10682 calling free_menubar_widget_value_tree directly (Bug#9830).
10684 2011-11-06 Paul Eggert <eggert@cs.ucla.edu>
10686 Fix some portability problems with 'inline'.
10687 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
10688 (window_box_width, window_box_left, window_box_left_offset)
10689 (window_box_right, window_box_right_offset): Declare extern.
10690 Otherwise, these inline functions do not conform to C99 and
10691 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
10692 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
10693 * intervals.c (adjust_intervals_for_insertion)
10694 (adjust_intervals_for_deletion): Now extern, because otherwise the
10695 extern inline functions 'offset_intervals' couldn't refer to it.
10696 (static_offset_intervals): Remove.
10697 (offset_intervals): Rewrite using the old contents of
10698 static_offset_intervals. The old version didn't conform to C99
10699 because an extern inline function contained a reference to an
10700 identifier with static linkage.

10812 * gtkutil.c (xg_make_tool_item): Add callbacks if one of wimage or
10813 label is not null (Bug#9951).

10846 * xdisp.c (try_cursor_movement): Make sure ROW isn't decremented
10847 past the beginning of the current glyph matrix.
10849 2011-10-30 Adam Sjøgren <asjo@koldfront.dk> (tiny change)
10851 * xterm.c: Include X11/Xproto.h if HAVE_GTK3.

10897 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
10898 Not clear what it was for, and it causes various bugs. (Bug#9839)
10900 2011-10-28 Eli Zaretskii <eliz@gnu.org>
10902 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a

10904 condition to clear the mouse face.
10906 2011-10-28 Chong Yidong <cyd@gnu.org>

10922 2011-10-28 Eli Zaretskii <eliz@gnu.org>
10924 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
10925 <oslsachem@gmail.com> for helping to debug this.
10927 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)

10933 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
10935 (w32font_open_internal, compute_metrics):
10936 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
10937 instead of calling the "wide" APIs directly.
10939 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
10941 * w32.h (syms_of_w32font): Add prototype.
10943 2011-10-27 Juanma Barranquero <lekktu@gmail.com>

10946 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
10947 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
10948 (Fmove_to_window_line): Doc fix.
10950 2011-10-27 Chong Yidong <cyd@gnu.org>
10952 * process.c (make_process): Set gnutls_state to NULL.
10954 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
10955 non-NULL, regardless of GNUTLS_INITSTAGE.
10956 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
10957 an error. Set process slots as soon as we allocate them.

10983 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
10985 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
10987 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
10989 * keyboard.c (test_undefined): New function (bug#9751).
10990 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
10992 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
10994 * sysdep.c (init_sys_modes): Fix the check for the controlling
10995 terminal (Bug#6649).
10997 2011-10-20 Eli Zaretskii <eliz@gnu.org>
10999 * dispextern.h (struct bidi_it): New member next_en_type.
11001 * bidi.c (bidi_line_init): Initialize the next_en_type member.
11002 (bidi_resolve_explicit_1): When next_en_pos is valid for the
11003 current character, check also for next_en_type being WEAK_EN.
11004 (bidi_resolve_weak): Don't enter the expensive loop if the current
11005 position is before next_en_pos. Record the bidi type of the first
11006 non-ET, non-BN character we find, in addition to its position.
11007 (bidi_level_of_next_char): Invalidate next_en_type when
11008 next_en_pos is over-stepped.
11010 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
11012 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
11013 * editfns.c: Rewrite current-time-zone so that it invokes
11014 the equivalent of (format-time-string "%Z") to get the time zone name.
11015 This fixes a bug when the time zone name contains characters that
11016 need converting from the system time locale to Emacs internal format.
11017 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
11018 that patch fixed format-time-string to do the conversion, but
11019 I forgot to fix current-time-zone.
11020 (format_time_string): New function, containing most of
11021 what Fformat_time_string used to contain.
11022 (Fformat_time_string): Rewrite in terms of format_time_string.
11023 This doesn't change this function's behavior.
11024 (current-time-zone): Rewrite to use format_time_string.
11025 This fixes the bug reported by Michael Schierl in
11026 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
11027 Jason Rumney's 2007-06-07 change worked around this bug, but
11029 * systime.h (tzname, timezone): Remove no-longer-used declarations.
11031 2011-10-19 Eli Zaretskii <eliz@gnu.org>
11033 * xdisp.c (start_display): If the character at POS is displayed
11034 via a display vector, reset IT->current.dpvec_index to zero.
11035 (try_window_reusing_current_matrix): If a line ends in a display
11036 vector or the next line starts in a display vector, continue
11037 redrawing the window even though the character position of
11038 start_row was reached.
11041 2011-10-18 Chong Yidong <cyd@gnu.org>
11043 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
11044 with nobreak-char-display too.
11046 2011-10-18 Eli Zaretskii <eliz@gnu.org>
11048 Fix part 3 of bug#9771.
11049 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
11050 (bidi_resolve_neutral): Don't enter the expensive loop looking for
11051 non-neutral characters if the current character is a paragraph
11052 separator (a.k.a. Newline). This avoids running the same
11053 expensive loop twice, once when we consume the preceding newline
11054 and the other time when the line actually needs to be displayed.
11055 Avoid the loop when we see neutrals on the base embedding level
11056 following a character whose directionality is the same as the
11057 paragraph's. This avoids running the expensive loop when a line
11058 ends in a long sequence of neutrals, like control characters.
11059 Add assertion against STRONG_AL type. Slightly rearrange code
11060 that determines the type of a neutral given the first non-neutral
11062 (bidi_level_of_next_char): Set next_en_pos to zero when
11063 invalidating its info.
11065 2011-10-17 Eli Zaretskii <eliz@gnu.org>
11067 * xdisp.c (push_display_prop): Determine whether to record string
11068 or buffer position by IT->string, not by IT->method. Allow
11069 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
11070 (move_it_vertically_backward): Don't look for character position
11071 immediately after the newline when in a continuation line.
11074 2011-10-15 Martin Rudalics <rudalics@gmx.at>
11076 * window.c (coordinates_in_window): Rewrite and delabelize
11077 vertical border check. (Bug#5357) (Bug#9618)
11079 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
11081 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
11082 errors in XSetWindowBorder (bug#9310).
11084 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
11086 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
11087 avoid crash when xmalloc overrun checking is enabled.
11089 2011-10-13 Eli Zaretskii <eliz@gnu.org>
11091 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
11092 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
11093 cursor motion with <left> and <right> arrow keys.
11095 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
11096 some callers set that themselves.
11098 2011-10-12 Eli Zaretskii <eliz@gnu.org>
11100 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
11101 display string and the previous row comes from the same string and
11102 is empty. (Bug#9739) (Bug#9738)
11104 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
11106 * doc.c (get_doc_string): Encode file name (bug#9735).
11108 2011-10-12 Eli Zaretskii <eliz@gnu.org>
11110 * bidi.c (bidi_level_of_next_char):
11111 * xdisp.c (get_visually_first_element): Remove old incorrect
11112 comments regarding the Unicode Line Separator character.
11114 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
11116 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
11118 * alloc.c (Fgc_status): Do not access beyond zombies array
11119 boundary if nzombies > MAX_ZOMBIES.
11120 * alloc.c (dump_zombies): Add missing format specifier.
11122 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
11124 * xdisp.c (set_cursor_from_row): Simplify conditionals,
11125 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
11127 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
11128 Some packages use them to denote characters with modifiers.
11130 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
11132 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
11133 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
11134 matching a pp-number. Rename parameter var to var1.
11136 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
11138 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
11140 2011-10-08 Glenn Morris <rgm@gnu.org>
11142 * callint.c (Fcall_interactively): Give a more explicit error for the
11143 'c' case with a non-character input. (Bug#8479)
11145 2011-10-08 Eli Zaretskii <eliz@gnu.org>
11147 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
11149 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
11150 lines that are hscrolled on the left.
11152 * dispnew.c (buffer_posn_from_coords): Account for a possible
11153 presence of header-line. (Bug#4426)
11155 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
11157 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
11158 Don't advertise functionality which we discourage or doesn't work.
11160 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
11162 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
11163 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
11164 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
11165 this makes Emacs dump core during garbage collection on rare
11166 occasions. sizeof is obviously inferior to offsetof here, so
11167 stick with offsetof.
11168 (GC_POINTER_ALIGNMENT): New macro.
11169 (mark_memory): Omit 3rd (offset) arg; caller changed.
11170 Don't assume EMACS_INT alignment is the same as pointer alignment.
11172 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
11174 * keyboard.c (read_key_sequence_remapped): New var.
11175 (read_key_sequence): Compute remapping in the right buffer.
11176 (command_loop_1): Use read_key_sequence's remapping directly.
11178 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
11180 * dired.c (file_name_completion): Don't expand file name.
11181 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
11182 before checking file name handler.
11184 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
11185 they've been requested explicitly (bug#9591).
11187 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
11189 * keymap.c (Fsingle_key_description): Use make_specified_string
11190 instead of build_string to build string from push_key_description.
11193 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
11195 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
11196 This fixes a Y2038 bug on 64-bit hosts.
11197 * buffer.c (reset_buffer):
11198 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
11199 (Fclear_buffer_auto_save_failure):
11200 Use 0, not -1, to represent an unset failure time, since time_t
11201 might not be signed.
11203 Remove dependency on glibc malloc internals.
11204 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11205 Move back here from lisp.h, but with their new implementations.
11206 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
11207 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
11208 * charset.c (charset_table_init): New static var.
11209 (syms_of_charset): Use it instead of xmalloc. This removes a
11210 dependency on glibc malloc internals. See Eli Zaretskii's comment in
11211 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
11212 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11213 Move back to alloc.c.
11214 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
11215 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
11217 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
11219 * nsterm.m (windowDidResize): Call x_set_window_size only when
11220 ns_in_resize is true. Otherwise set pixelwidth/height and
11221 call change_frame_size (Bug#9628).
11223 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
11225 Port --enable-checking=all to Fedora 14 x86-64.
11226 * charset.c (syms_of_charset): Also account for glibc malloc's
11227 internal overhead when calculating the initial malloc maximum.
11229 Port --enable-checking=all to Fedora 14 x86.
11230 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11232 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
11233 (overrun_check_realloc, overrun_check_free):
11234 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
11235 That way, xmalloc returns a properly-aligned pointer even if
11236 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
11237 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
11238 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
11239 into account when calculating the initial malloc maximum.
11240 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11241 Move here from alloc.c, so that charset.c can use it too.
11242 Properly align; the old code wasn't right for common 32-bit hosts
11243 when configured with --enable-checking=all.
11244 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
11245 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
11247 2011-09-29 Eli Zaretskii <eliz@gnu.org>
11249 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
11252 2011-09-28 Eli Zaretskii <eliz@gnu.org>
11254 * xdisp.c (compute_display_string_end): If there's no display
11255 string at CHARPOS, return -1.
11257 * bidi.c (bidi_fetch_char): When compute_display_string_end
11258 returns a negative value, treat the character as a normal
11259 character not covered by a display string. (Bug#9624)
11261 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
11263 * lread.c (Fread_from_string): Fix typo in docstring.
11265 2011-09-27 Eli Zaretskii <eliz@gnu.org>
11267 * xdisp.c (handle_invisible_prop): If invisible text ends on a
11268 newline, reseat the iterator instead of bidi-iterating there one
11269 character at a time. (Bug#9610)
11270 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
11271 TO_CHARPOS if the bidi iterator is at base embedding level.
11273 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
11275 * lread.c (readevalloop): Use correct code for NBSP.
11276 (read1): Likewise. (Bug#9608)
11278 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
11280 * dbusbind.c (Fdbus_register_signal): When service is not
11281 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
11283 2011-09-25 Glenn Morris <rgm@gnu.org>
11285 * buffer.c (truncate-lines): Doc fix.
11287 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
11289 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
11290 (Fset_window_next_buffers): Doc fix.
11292 2011-09-24 Glenn Morris <rgm@gnu.org>
11294 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
11296 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
11298 Fix minor problems found by static checking.
11299 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
11300 * indent.c (Fvertical_motion): Fix == vs = typo.
11302 2011-09-24 Eli Zaretskii <eliz@gnu.org>
11304 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
11305 Default value is now t. Doc fix.
11307 * indent.c (Fvertical_motion): Compute and apply the overshoot
11308 logic when moving up, not only when moving down. Fix the
11309 confusing name and values of the it_overshoot_expected variable;
11310 logic changes accordingly. (Bug#9254) (Bug#9549)
11312 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
11313 CHARPOS is covered by a display string which includes newlines.
11314 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
11315 is covered by a display string with embedded newlines.
11317 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
11319 * dbusbind.c (Fdbus_register_signal): Add match rule to
11320 Vdbus_registered_objects_table. (Bug#9581)
11321 (Fdbus_register_method, Vdbus_registered_objects_table):
11324 2011-09-24 Jim Meyering <meyering@redhat.com>
11326 do not ignore write error for any output size
11327 The previous change was incomplete.
11328 While it makes emacs --batch detect the vast majority of stdout
11329 write failures, errors were still ignored whenever the output size is
11330 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
11331 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
11332 && echo FAIL: ignored write error
11333 FAIL: ignored write error
11334 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
11335 && echo FAIL: ignored write error
11336 FAIL: ignored write error
11337 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
11339 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
11341 * emacs.c (Fkill_emacs): In noninteractive mode exit
11342 non-successfully if a write error occurred on stdout. (Bug#9574)
11344 2011-09-21 Eli Zaretskii <eliz@gnu.org>
11346 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
11349 * dispextern.h (struct it): Update the comment documenting what
11352 2011-09-20 Eli Zaretskii <eliz@gnu.org>
11354 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
11355 a display string, extend search for cursor position to end of row.
11356 (find_row_edges): If the row ends in a newline from a display
11357 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
11358 Handle the case of a display string with multiple newlines.
11359 (Fcurrent_bidi_paragraph_direction): Fix search for previous
11360 non-empty line. Fixes confusing cursor motion with arrow keys at
11361 the beginning of a line that starts with whitespace.
11363 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
11365 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
11368 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
11370 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
11371 boolean (Bug#9154).
11373 2011-09-18 Eli Zaretskii <eliz@gnu.org>
11375 * xdisp.c (display_line): Record maximum and minimum buffer
11376 positions even if no glyphs were produced (e.g., by a zero-width
11377 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
11378 buffer positions that will be removed from the glyph row because
11380 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
11381 column is beyond frame width: don't subtract 1 "pixel" when
11382 computing width of the stretch.
11383 (reseat_at_next_visible_line_start): Undo the change made on
11384 2011-09-17 that saved paragraph information and restored it after
11385 the call to `reseat'. (Bug#9545)
11387 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11389 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
11390 and turn window cursor on if cleared (Bug#9415).
11392 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
11394 * search.c (boyer_moore): Take unibyte characters from pattern
11395 literally. (Bug#9458)
11397 2011-09-18 Eli Zaretskii <eliz@gnu.org>
11399 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
11401 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
11403 Fix minor problem found by static checking.
11404 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
11405 initialized, to pacify gcc -Wuninitialized.
11407 * fileio.c: Report proper errno when syscall falls.
11408 (Finsert_file_contents): Save and restore errno,
11409 so that report_file_error outputs the correct diagnostic.
11410 (Fwrite_region) [CLASH_DETECTION]: Likewise.
11412 2011-09-18 Eli Zaretskii <eliz@gnu.org>
11414 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
11416 2011-09-17 Eli Zaretskii <eliz@gnu.org>
11418 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
11419 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
11421 2011-09-17 Eli Zaretskii <eliz@gnu.org>
11423 * xdisp.c (reseat_at_next_visible_line_start): Keep information
11424 about the current paragraph and restore it after the call to reseat.
11426 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
11427 (bidi_find_paragraph_start): Search back for paragraph beginning
11428 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
11429 (bidi_move_to_visually_next): Only trigger paragraph-related
11430 computations when the last character is a newline or at EOB, not
11431 just any NEUTRAL_B. (Bug#9470)
11433 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
11434 truncated lines if point is covered by a display string. (Bug#9524)
11436 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
11438 * xselect.c: Relax test for outgoing X longs (Bug#9498).
11439 (cons_to_x_long): New function.
11440 (lisp_data_to_selection_data): Use it. Correct the test for
11441 short-versus-long data; it was negated. Break out of vector
11442 loop, for efficiency, when a long datum is discovered.
11444 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
11446 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
11448 2011-09-16 Eli Zaretskii <eliz@gnu.org>
11450 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
11451 GCC PR/17406) by declaring this function with external scope.
11453 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
11455 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
11456 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
11458 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>

11469 (fill_composite_glyph_string): Add comments about special meaning
11470 of TAB characters in a composition.
11472 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
11474 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
11475 This occurs when processing a multibyte format.
11476 Problem reported by Wolfgang Jenker.
11478 2011-09-15 Johan Bockgård <bojohan@gnu.org>
11480 * xdisp.c (try_cursor_movement): Only check for exact match if
11481 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
11483 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
11485 Remove unused external symbols.
11486 * dispextern.h (calc_pixel_width_or_height): Remove decl.
11487 * xdisp.c (calc_pixel_width_or_height): Now static.
11488 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
11489 * indent.c (check_display_width):
11490 * w32term.c: Fix comment to match code.
11491 * xterm.c, xterm.h (x_catching_errors): Remove.
11493 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
11495 * xselect.c: Use signed conversions more consistently (Bug#9498).
11496 (selection_data_to_lisp_data): Assume incoming selection data are
11497 signed integers, not unsigned. This is to be consistent with
11498 outgoing selection data, which was modified to use signed integers
11499 in as part of the fix to Bug#9196 in response to Jan D.'s comment
11500 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
11501 expects long, not unsigned long.
11503 2011-09-14 Eli Zaretskii <eliz@gnu.org>
11505 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
11506 computation of loop end. Reported by Johan Bockgård
11509 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
11511 * frame.c (Fother_visible_frames_p): Function deleted.
11513 2011-09-12 Eli Zaretskii <eliz@gnu.org>
11515 * indent.c (compute_motion): Process display vector front to back
11516 rather than the other way around. (Bug#2496)
11518 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
11520 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
11522 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
11524 * minibuf.c (Fread_from_minibuffer): Doc fix.
11526 2011-09-11 Eli Zaretskii <eliz@gnu.org>
11528 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
11529 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
11531 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
11533 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
11534 value for non-existent files.
11536 2011-09-11 Eli Zaretskii <eliz@gnu.org>
11538 * fileio.c (Finsert_file_contents): If the file cannot be opened,
11539 set its "size" to -1. This will set the modtime_size field of
11540 the corresponding buffer to -1, which is what
11541 verify-visited-file-modtime expects for files that do not exist.
11544 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
11546 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
11548 * lisp.h: ... from here. push_key_description is no longer
11549 defined in keyboard.c, so its declaration should not be in
11550 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
11551 logically belongs with push_key_description.
11553 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
11555 * buffer.h: Include <sys/types.h> instead of <time.h>.
11556 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
11557 Problem reported by Herbert J. Skuhra.
11559 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
11561 * xml.c (parse_region): Make the parsing work for
11562 non-comment-starting XML files again (bug#9144).
11564 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
11566 * image.c (gif_load): Fix calculation of bottom and right corner.
11569 2011-09-10 Eli Zaretskii <eliz@gnu.org>
11571 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
11572 redisplay in small windows.
11574 2011-09-09 Eli Zaretskii <eliz@gnu.org>
11576 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
11578 2011-09-08 Martin Rudalics <rudalics@gmx.at>
11580 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
11581 Operate on live windows only.
11583 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
11585 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
11587 2011-09-07 Eli Zaretskii <eliz@gnu.org>
11589 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
11590 only under bidi iteration.
11592 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
11594 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
11596 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
11598 isnan: Fix porting problem to Solaris 10 with bundled gcc.
11599 Without this fix, the command to link temacs failed due to an
11600 undefined symbol __builtin_isnan. This is because
11601 /usr/include/iso/math_c99.h #defines isnan(x) to
11602 __builtin_isnan(x), but the bundled gcc, which identifies itself
11603 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
11605 * floatfns.c (isnan): #undef, and then #define to a clone of
11607 (Fisnan): Always define, since it's always available now.
11608 (syms_of_floatfns): Always define isnan at the Lisp level.
11610 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
11612 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
11614 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
11616 * fileio.c: Fix bugs with large file offsets (Bug#9428).
11617 The previous code assumed that file offsets (off_t values) fit in
11618 EMACS_INT variables, which is not true on typical 32-bit hosts.
11619 The code messed up by falsely reporting buffer overflow in cases
11620 such as (insert-file-contents "big" nil 1 2) into an empty buffer
11621 when "big" contains more than 2**29 bytes, even though this
11622 inserts just one byte and does not overflow the buffer.
11623 (Finsert_file_contents): Store file offsets as off_t
11624 values, not as EMACS_INT values. Check for overflow when
11625 converting between EMACS_INT and off_t. When checking for
11626 buffer overflow or for overlap, take the offsets into account.
11627 Don't use EMACS_INT for small values where int suffices.
11628 When checking for overlap, fix a typo: ZV was used where
11629 ZV_BYTE was intended.
11630 (Fwrite_region): Don't assume off_t fits into 'long'.
11631 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
11633 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
11635 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
11637 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
11639 sprintf-related integer and memory overflow issues (Bug#9412).
11641 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
11642 (esprintf, exprintf, evxprintf): New functions.
11643 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
11644 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
11645 (modify_event_symbol): Do not assume that the length of
11646 name_alist_or_stem is safe to alloca and fits in int.
11647 (Fexecute_extended_command): Likewise for function name and binding.
11648 (Frecursion_depth): Wrap around reliably on integer overflow.
11649 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
11650 since some callers pass EMACS_INT values.
11651 (Fsingle_key_description): Don't crash if symbol name contains more
11652 than MAX_ALLOCA bytes.
11653 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
11654 (get_minibuffer): Arg is now EMACS_INT, not int.
11655 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
11656 (esprintf, exprintf, evxprintf): New decls.
11657 * window.h (command_loop_level, minibuf_level): Reflect API changes.
11659 * dbusbind.c (signature_cat): New function.
11660 (xd_signature, Fdbus_register_signal):
11661 Do not overrun buffer; instead, report string overflow.
11663 * dispnew.c (add_window_display_history): Don't overrun buffer.
11664 Truncate instead; this is OK since it's just a log.
11666 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
11667 even if the time zone offset is outlandishly large.
11668 Don't mishandle offset == INT_MIN.
11670 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
11671 when creating daemon; the previous buffer-overflow check was incorrect.
11673 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
11674 which has the guts of the old verror function.
11676 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
11677 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
11679 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
11680 (font_unparse_xlfd): Don't blindly alloca long strings.
11681 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
11682 fits in int, when using sprintf. Use single snprintf to count
11683 length of string rather than counting it via multiple sprintfs;
11684 that's simpler and more reliable.
11685 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
11686 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
11687 sprintf, in case result does not fit in int.
11689 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
11690 (fontset_from_font): Print it.
11692 * frame.c (tty_frame_count): Now printmax_t, not int.
11693 (make_terminal_frame, set_term_frame_name): Print it.
11694 (x_report_frame_params): In X, window IDs are unsigned long,
11695 not signed long, so print them as unsigned.
11696 (validate_x_resource_name): Check for implausibly long names,
11697 and don't assume name length fits in 'int'.
11698 (x_get_resource_string): Don't blindly alloca invocation name;
11699 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
11702 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
11703 (xg_check_special_colors, xg_set_geometry):
11704 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
11706 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
11707 Use esprintf, not sprintf, in case result does not fit in int.
11709 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
11710 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
11711 it as a large positive number.
11712 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
11713 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
11715 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
11716 in case result does not fit in int.
11718 * print.c (float_to_string): Detect width overflow more reliably.
11719 (print_object): Make sprintf buffer a bit bigger, to avoid potential
11720 buffer overrun. Don't assume list length fits in 'int'. Treat
11721 print length of 0 as 0, not as infinity; to be consistent with other
11722 uses of print length in this function. Don't overflow print length
11723 index. Don't assume hash table size fits in 'long', or that
11724 vectorlike size fits in 'unsigned long'.
11726 * process.c (make_process): Use printmax_t, not int, to format
11727 process-name gensyms.
11729 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
11731 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
11732 to avoid potential buffer overrun.
11734 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
11735 if X resource line is longer than 512 bytes.
11737 * xfns.c (x_window): Make sprintf buffer a bit bigger
11738 to avoid potential buffer overrun.
11740 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
11742 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
11744 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
11746 Integer overflow fixes for scrolling, etc.
11747 Without these, Emacs silently mishandles large integers sometimes.
11748 For example, "C-u 4294967297 M-x recenter" was treated as if
11749 it were "C-u 1 M-x recenter" on a typical 64-bit host.
11751 * xdisp.c (try_window_id): Check Emacs fixnum range before
11752 converting to 'int'.
11754 * window.c (window_scroll_line_based, Frecenter):
11755 Check that an Emacs fixnum is in range before assigning it to 'int'.
11756 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
11757 values converted from Emacs fixnums.
11758 (Frecenter): Don't wrap around a line count if it is out of 'int'
11759 range; instead, treat it as an extreme value.
11760 (Fset_window_configuration, compare_window_configurations):
11761 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
11763 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
11764 that can exceed INT_MAX. Check that EMACS_INT value is in range
11765 before assigning it to the (possibly-narrower) index.
11766 (match_limit): Don't assume that a fixnum can fit in 'int'.
11768 * print.c (print_object): Use ptrdiff_t, not int, for index that can
11771 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
11772 (Fvertical_motion): Don't wrap around LINES values that don't fit
11773 in 'int'. Instead, treat them as extreme values. This is good
11774 enough for windows, which can't have more than INT_MAX lines anyway.
11776 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
11778 * Require libxml/parser.h to avoid compilation warning.
11780 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
11782 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
11783 since this reportedly can destroy thread storage.
11785 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
11787 * syntax.c (find_defun_start): Update all cache variables if
11788 exiting early (Bug#9401).
11790 2011-08-30 Eli Zaretskii <eliz@gnu.org>
11792 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
11794 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
11795 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
11796 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
11798 * term.c (tty_append_glyph): New function.
11799 (produce_stretch_glyph): Static function and its prototype deleted.
11801 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
11804 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
11806 * image.c (parse_image_spec): Check for nonnegative, not for positive,
11807 when checking :margin (Bug#9390).
11808 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
11809 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
11810 so that the name doesn't mislead. All uses changed.
11812 2011-08-28 Johan Bockgård <bojohan@gnu.org>
11814 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
11817 2011-08-27 Eli Zaretskii <eliz@gnu.org>
11819 * xdisp.c (move_it_to): Don't bail out early when reaching
11820 position beyond to_charpos, if we are scanning backwards.
11821 (move_it_vertically_backward): When DY == 0, make sure we get to
11822 the first character in the line after the newline.
11824 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
11826 * ccl.c: Improve and simplify overflow checking (Bug#9196).
11827 (ccl_driver): Do not generate an out-of-range pointer.
11828 (Fccl_execute_on_string): Remove unnecessary check for
11829 integer overflow, noted by Stefan Monnier in
11830 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
11831 Remove a FIXME that didn't need fixing.
11832 Simplify the newly-introduced buffer reallocation code.
11834 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
11836 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
11838 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
11840 Integer and memory overflow issues (Bug#9196).
11842 * doc.c (get_doc_string): Rework so that
11843 get_doc_string_buffer_size is the actual buffer size, rather than
11844 being 1 less than the actual buffer size; this makes xpalloc more
11847 * image.c (x_allocate_bitmap_record, cache_image):
11848 * xselect.c (Fx_register_dnd_atom):
11849 Simplify previous changes by using xpalloc.
11851 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
11852 since either will do and ptrdiff_t is convenient with xpalloc.
11854 * charset.c (charset_table_size)
11855 (struct charset_sort_data.priority): Now ptrdiff_t.
11856 (charset_compare): Don't overflow if priorities differ greatly.
11857 (Fsort_charsets): Don't assume list length fits in int.
11858 Check for size-calculation overflow when allocating sort data.
11859 (syms_of_charset): Allocate an initial charset table that is
11860 just under 64 KiB, to avoid problems with glibc malloc and mmap.
11862 * cmds.c (internal_self_insert): Check for size-calculation overflow.
11864 * composite.h (struct composition.glyph_len): Now int, not unsigned.
11865 The actual value is always <= INT_MAX, and leaving it unsigned made
11866 overflow checking harder.
11868 * dispextern.h (struct glyph_matrix.rows_allocated)
11869 (struct face_cache.size): Now ptrdiff_t, for convenience in use
11870 with xpalloc. The values are still always <= INT_MAX.
11872 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
11874 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
11875 (SAFE_NALLOCA): New macro.
11877 * region-cache.c (struct boundary.pos, find_cache_boundary)
11878 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
11879 (set_cache_region, invalidate_region_cache)
11880 (revalidate_region_cache, know_region_cache, region_cache_forward)
11881 (region_cache_backward, pp_cache):
11882 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
11883 so that ptrdiff_t * can be passed to xpalloc.
11884 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
11885 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
11886 (pp_cache): Don't assume cache_len fits in int.
11887 * region-cache.h: Adjust extern decls to match.
11889 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
11890 EMACS_INT, since either will do, for xpalloc.
11892 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
11893 (xnmalloc, xnrealloc, xpalloc): New functions.
11895 * bidi.c (bidi_shelve_header_size): New constant.
11896 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
11897 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
11899 * bidi.c (bidi_cache_shrink):
11900 * buffer.c (overlays_at, overlays_in, record_overlay_string)
11902 Don't update size of array until after memory allocation succeeds,
11903 because xmalloc/xrealloc may not return.
11904 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
11905 now that we have proper integer overflow checking.
11906 (record_overlay_string, overlay_strings): Catch overflows when
11907 calculating size of overlay_str_buf.
11909 * callproc.c (Fcall_process): Check for size overflow when
11910 calculating size of args2.
11911 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
11912 Normally we prefer signed values, but sticking with ptrdiff_t would
11913 require adding more-complicated checks.
11915 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
11916 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
11917 Redo buffer-overflow calculations to avoid integer overflow.
11918 Add a FIXME comment where memory seems to be over-allocated.
11920 * character.c (Fstring): Check for size-calculation overflow.
11922 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
11923 unnecessary integer overflow. Check for size overflow.
11924 (encode_coding_object): Don't update size until xmalloc succeeds.
11926 * composite.c (get_composition_id): Check for overflow in glyph
11927 length calculations.
11929 Integer and memory overflow fixes for display code.
11930 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
11931 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
11932 (scrolling_window): Check for overflow in size calculations.

11936 (row_table_size): Now ptrdiff_t, not int.
11937 (scrolling_window): Avoid overflow in size calculations.
11938 Don't update size until allocation succeeds.
11939 * fns.c (concat): Check for overflow in size calculations.
11940 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
11941 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.

11944 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
11945 (get_doc_string): Check for size calculation overflow.
11946 Don't update size until allocation succeeds.
11947 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
11948 EMACS_INT, where ptrdiff_t will do.
11949 (Fsubstitute_command_keys): Check for string overflow.
11951 * editfns.c (set_time_zone_rule): Don't assume environment length
11953 (message_length): Now ptrdiff_t, not int.
11954 (Fmessage_box): Don't update size until allocation succeeds.
11955 Don't assume message length fits in int.
11956 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
11958 * emacs.c (main): Do not reallocate argv, since there is a null at
11959 the end that can be overwritten, and this way there's no need to
11960 worry about size-calculation overflow.
11961 (sort_args): Check for size-calculation overflow.
11963 * eval.c (init_eval_once, grow_specpdl): Don't update size until
11965 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
11967 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
11968 (x_set_scroll_bar_width, x_figure_window_size):
11969 Check for integer overflow.
11970 (x_set_alpha): Do not assume XINT fits in int.
11972 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
11973 This is for the members text_lines, text_cols, total_lines, total_cols,
11974 where the system imposes an 'int' limit.
11976 * fringe.c (Fdefine_fringe_bitmap):
11977 Don't update size until alloc works.
11979 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
11980 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
11982 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
11983 Check for size-calculation overflow.
11984 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
11985 do, as we prefer signed integers.
11986 (id_to_widget.max_size, id_to_widget.used)
11987 (xg_store_widget_in_map, xg_remove_widget_from_map)
11988 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
11989 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
11990 Use and return ptrdiff_t, not int.
11991 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
11992 * gtkutil.h: Change prototypes to match the above.
11994 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
11995 are duplicate now that they've been promoted to lisp.h.
11996 (x_allocate_bitmap_record, x_alloc_image_color)
11997 (make_image_cache, cache_image, xpm_load):
11998 Don't update size until alloc is done.
11999 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)

12008 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
12009 Use ptrdiff_t, not int, to count maps.
12010 (read_char_minibuf_menu_prompt): Check for overflow in size
12011 calculations. Don't update size until allocation succeeds.
12012 Redo calculations to avoid overflow.
12013 * keyboard.h: Change prototypes to match the above.
12015 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
12017 (current_minor_maps): Check for size calculation overflow.
12018 * keymap.h: Change prototypes to match the above.
12020 * lread.c (read1, init_obarray): Don't update size until alloc done.
12022 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.

12041 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
12042 for command line length. Do not attempt to address one before the
12043 beginning of an array, as that's not portable.
12045 * term.c (max_frame_lines): Remove; unused.
12046 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
12048 (encode_terminal_code, calculate_costs): Check for size
12049 calculation overflow.

12071 Use ptrdiff_t, not int, for sizes.
12072 (Finternal_make_lisp_face, cache_face):
12073 Check for size calculation overflow.
12074 (cache_face): Treat size calculation overflows as if they were
12075 memory exhaustion (the usual treatment), rather than aborting.
12077 * xfns.c (x_encode_text, x_set_name_internal)
12078 (Fx_change_window_property): Use ptrdiff_t, not int, to count
12079 sizes, since they can exceed INT_MAX in size. Check for size
12080 calculation overflow.
12082 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
12083 (xg_select): Check for size calculation overflow.
12084 Don't update size until alloc done.
12086 * xrdb.c (get_environ_db): Don't assume path length fits in int,
12087 as sprintf is limited to int lengths.
12089 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
12090 (X_LONG_MIN): New macros.
12091 Use them to make the following changes clearer.
12092 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
12093 This change doesn't affect the value now, but it may help remind
12094 future maintainers not to raise the value too much later.
12095 (SELECTION_QUANTUM): Remove, replacing with ...
12096 (selection_quantum): ... new function, which avoids overflow.
12098 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
12099 assumption that selection length fits in 'int'.
12100 (x_reply_selection_request, x_handle_selection_request)
12101 (x_get_window_property, receive_incremental_selection)
12102 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
12103 (lisp_data_to_selection_data, clean_local_selection_data):
12104 Use ptrdiff_t, not int, to record length of selection.
12105 (x_reply_selection_request, x_get_window_property)
12106 (receive_incremental_selection, x_property_data_to_lisp):
12107 Redo calculations to avoid overflow.
12108 (x_reply_selection_request): When sending hint, ceiling it at
12109 X_LONG_MAX rather than relying on wraparound overflow to send
12111 (x_get_window_property, receive_incremental_selection)
12112 (lisp_data_to_selection_data, x_property_data_to_lisp):
12113 Check for size-calculation overflow.
12114 (x_get_window_property, receive_incremental_selection)

12116 Don't store size until memory allocation succeeds.
12117 (x_get_window_property): Plug memory leak on memory exhaustion.
12118 Don't double-block input; malloc is safe here. Don't assume 2**34
12119 - 4 fits in unsigned long. Add an xassert to check
12120 XGetWindowProperty overflow. Be more careful about overflow
12121 calculations, and distinguish size from memory overflow better.
12122 (receive_incremental_selection): When tracing, don't assume
12123 unsigned int is less than INT_MAX.
12124 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
12125 harmful) conversions of unsigned short to int.
12126 (lisp_data_to_selection_data): Don't assume that integers
12127 in the range -65535 through -1 fit in an X unsigned short.
12128 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
12129 result parameters unless successful. Rely on cons_to_unsigned
12130 to report problems with elements; the old code wasn't right anyway.
12131 (x_check_property_data): Check for int overflow; we cannot use
12132 a wider type due to X limits.
12133 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
12135 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.
12137 * xterm.c (x_color_cells, x_send_scrollbar_event, handle_one_xevent)
12138 (x_term_init): Check for size calculation overflow.
12139 (x_color_cells): Don't store size until memory allocation succeeds.
12140 (handle_one_xevent): Use ptrdiff_t, not int, for byte counts.
12141 Don't assume alloca size is less than MAX_ALLOCA.
12142 (x_term_init): Don't assume length fits in int (sprintf is limited
12145 Use ptrdiff_t for composition IDs.
12146 * character.c (lisp_string_width):
12147 * composite.c (composition_table_size, n_compositions)
12148 (get_composition_id, composition_gstring_from_id):

12164 * image.c (xpm_get_color_table_h):
12165 * lisp.h (hash_lookup, hash_put):
12166 * minibuf.c (Ftest_completion):
12167 Use ptrdiff_t for hash table indexes, not int (which is too
12168 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
12169 32-bit --with-wide-int hosts).
12171 * charset.c (Fdefine_charset_internal): Check for integer overflow.
12172 Add a FIXME comment about memory leaks.
12173 (syms_of_charset): Don't assume xmalloc returns.

12177 * character.h (CHAR_WIDTH):
12178 * indent.c (MULTIBYTE_BYTES_WIDTH):
12179 Use sanitize_char_width to avoid undefined and/or bad behavior
12180 with outlandish widths.
12181 * character.h (sanitize_tab_width): Rename from sanitize_width,
12182 now that we have two such functions. All uses changed.
12183 (sanitize_char_width): New inline function.
12185 Don't assume that tab-width fits in int.
12186 * character.h (sanitize_width): New inline function.
12187 (SANE_TAB_WIDTH): New macro.
12188 (ASCII_CHAR_WIDTH): Use it.
12189 * indent.c (sane_tab_width): Remove. All uses replaced by

12193 * fileio.c: Integer overflow issues with file modes.
12194 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
12196 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
12197 Remove unreachable code.
12198 (read_hex, load_charset_map_from_file): Check for integer overflow.
12200 * xterm.c: Don't go over XClientMessageEvent limit.
12201 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
12202 (x_send_scroll_bar_event): Likewise. Check that the size does not
12203 exceed limits imposed by XClientMessageEvent, as well as the usual
12204 ptrdiff_t and size_t limits.
12206 * keyboard.c: Overflow, signedness and related fixes.
12207 (make_lispy_movement): Use same integer type in forward decl
12208 that is used in the definition.
12209 (read_key_sequence, keyremap_step):
12210 Change bufsize argument back to int, undoing my 2011-03-30 change.
12211 We prefer signed types, and int is wide enough here.
12212 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
12213 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
12214 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
12215 length, not size_t. Use ptrdiff_t for index, not int.
12216 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
12217 possibility of integer overflow.
12219 Overflow, signedness and related fixes for images.
12221 * dispextern.h (struct it.stack[0].u.image.image_id)
12222 (struct_it.image_id, struct image.id, struct image_cache.size)

12229 * xdisp.c (calc_pixel_width_or_height):
12230 * xfns.c (image_cache_refcount):
12231 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits

12240 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
12241 (lookup_image): Remove unnecessary tests.
12242 (xbm_image_p): Locals are now of int, not EMACS_INT,
12243 since parse_image_check makes sure they fit into int.
12244 (png_load, gif_load, svg_load_image):
12245 Prefer int to unsigned where either will do.
12246 (tiff_handler): New function, combining the cores of the
12247 old tiff_error_handler and tiff_warning_handler.
12248 This function is rewritten to use vsnprintf and thereby avoid
12249 stack buffer overflows. It uses only the features of vsnprintf
12250 that are common to both POSIX and native Microsoft.
12251 (tiff_error_handler, tiff_warning_handler): Use it.
12252 (tiff_load, gif_load, imagemagick_load_image):
12253 Don't assume :index value fits in 'int'.
12254 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
12255 (imagemagick_load_image): Check that crop parameters fit into
12256 the integer types that MagickCropImage accepts. Don't assume
12257 Vimagemagick_render_type has a nonnegative value. Don't assume
12258 size_t fits in 'long'.
12259 (gs_load): Use printmax_t to print the widest integers possible.
12260 Check for integer overflow when computing image height and width.
12262 2011-08-26 Eli Zaretskii <eliz@gnu.org>
12264 * xdisp.c (redisplay_window): Don't force window start if point
12265 will be invisible in the resulting window. (Bug#9324)

12269 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
12270 the display spec is of the form `(space ...)'.
12271 (handle_display_spec): Return the value returned by
12272 handle_single_display_spec, not just 1 or zero.
12273 (handle_single_display_spec): If the display spec is of the form
12274 `(space ...)', and specifies display in the text area, return 2
12276 (try_cursor_movement): Check for the need to scroll more
12277 accurately, and prefer exact match for point under bidi.
12278 Don't advance `row' beyond the last row of the window.
12280 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
12281 into disp_prop; all users changed.
12283 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
12284 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
12285 for the text covered by the display property.

12295 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
12296 buffers, return left-to-right.
12297 (set_cursor_from_row): Consider candidate row a win if its glyph
12298 represents a newline and point is on that newline. Fixes cursor
12299 positioning on the newline at EOL of R2L text within L2R
12300 paragraph, and vice versa.
12301 (try_cursor_movement): Check continued rows, in addition to
12302 continuation rows. Fixes unwarranted scroll when point enters a
12303 continued line of R2L text within an L2R paragraph, or vice versa.
12304 (cursor_row_p): Consider the case of point being equal to
12305 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
12306 from the end of a short line to the beginning of a continued line
12307 of R2L text within L2R paragraph.
12308 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
12309 composed characters.
12311 * bidi.c (bidi_check_type): Use xassert.

12324 2011-08-22 Kenichi Handa <handa@m17n.org>
12326 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
12327 extra slot even if the purpose is char-code-property-table.
12329 2011-08-23 Eli Zaretskii <eliz@gnu.org>
12331 * xdisp.c (redisplay_window): When computing centering_position,
12332 account for the height of the header line. (Bug#8874)
12334 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
12335 instead of CHAR_TO_BYTE. Fixes a crash when a completion
12336 candidate is selected by the mouse, and that candidate has a
12337 composed character under the mouse.
12339 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
12340 coordinates reported by pos-visible-in-window-p for a composed
12341 character in column zero.
12343 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
12345 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
12347 2011-08-22 Eli Zaretskii <eliz@gnu.org>
12349 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
12350 consider it a hit if to_charpos is anywhere in the range of the
12351 composed buffer positions.
12353 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
12355 * image.c (gif_load): Don't assume that each subimage has the same
12356 dimensions as the base image. Handle disposal method that is
12357 "undefined" by the gif spec (Bug#9335).
12359 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
12361 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).
12362 (Fcondition_case): Document `debug' symbol in error handler.
12364 2011-08-19 Eli Zaretskii <eliz@gnu.org>
12366 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
12367 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
12368 from an Org mode buffer to a Speedbar frame.
12370 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
12371 a composition, take its buffer position from IT->cmp_it.charpos.
12372 Fixes cursor positioning at the beginning of a line that begins
12373 with a composed character.
12375 2011-08-18 Eli Zaretskii <eliz@gnu.org>
12377 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
12378 character bidirectional type, use STRONG_L instead. Fixes crashes
12379 in a buffer produced by `describe-categories'.
12381 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
12382 members before the level stack, so they would be saved and
12383 restored when copying iterator state. Fixes incorrect reordering
12384 around TABs covered by display properties.
12386 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
12388 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

12392 * eval.c (internal_condition_case, internal_condition_case_1)
12393 (internal_condition_case_2, internal_condition_case_n):
12394 Remove unnecessary aborts (Bug#9081).
12396 2011-08-17 Eli Zaretskii <eliz@gnu.org>
12398 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
12399 has no `load' handler, try opening the file locally. (Bug#9311)
12401 2011-08-16 Ken Brown <kbrown@cornell.edu>
12403 * gmalloc.c: Expand comment.

12407 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
12408 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.
12410 2011-08-16 Ken Brown <kbrown@cornell.edu>
12412 Fix memory allocation problems in Cygwin build (Bug#9273).
12414 * unexcw.c ( __malloc_initialized): Declare external variable.
12415 (fixup_executable): Force the dumped emacs to reinitialize malloc.
12417 * gmalloc.c [CYGWIN] (bss_sbrk_heapbase, bss_sbrk_heapinfo):
12419 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the

12447 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
12448 coordinates of the iterator when restoring from ppos_it.
12451 2011-08-14 Kenichi Handa <handa@m17n.org>
12453 * process.c (create_process): Call setup_process_coding_systems
12454 after the pid of the process is set to -1 (Bug#8162).
12456 2011-08-14 Eli Zaretskii <eliz@gnu.org>
12458 * xdisp.c (move_it_in_display_line_to): Don't invoke
12459 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
12460 ppos_it. Fixes vertical cursor motion when line beginning is
12461 covered by an image. (Bug#9296)
12463 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
12465 * nsterm.h (ns_run_ascript): Declare.
12466 (NSAPP_DATA2_RUNASSCRIPT): Define.
12468 * nsfns.m (as_script, as_result, as_status): New static variables.
12469 (ns_run_ascript): New function.
12470 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
12471 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
12472 the event loop. Get status from as_status (Bug#7276).
12474 * nsterm.m (sendEvent): If event is NSApplicationDefined and
12475 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
12476 the event loop (Bug#7276).
12478 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
12480 * gnutls.c (QCgnutls_bootprop_priority)

12501 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
12502 (Fnetwork_interface_list): Allocate in increments of bytes instead
12503 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
12504 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
12506 (struct ifflag_def): notrailers is smart on OSX.
12507 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
12508 Get hardware address with getifaddrs if available.
12510 2011-08-12 Eli Zaretskii <eliz@gnu.org>
12512 * xdisp.c (iterate_out_of_display_property): xassert that
12513 IT->position is set to within IT->object's boundaries. Break from
12514 the loop as soon as EOB is reached; avoids infloops in redisplay
12515 when IT->position is set up wrongly due to some bug.
12516 Set IT->current to match the bidi iterator unconditionally.
12517 (push_display_prop): Allow GET_FROM_STRING as IT->method on
12518 entry. Force push_it to save on the stack the current
12519 buffer/string position, to be restored by pop_it. Fix flags in
12520 the iterator structure wrt the object coming from a display
12521 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
12522 properties. (Bug#9284)
12524 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
12526 * fontset.c (fontset_get_font_group): Add proper type checks.

12539 no-display-properties-and-no-overlays under bidi display.
12540 Set disp_pos in the bidi iterator to avoid searches for display
12541 properties and overlays.
12543 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
12545 * editfns.c (Fset_time_zone_rule): Document relationship with the

12549 the font entity extracted from the cache (Bug#8109).
12551 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
12553 * composite.c (autocmp_chars): Don't reset point. That is done by
12554 restore_point_unwind (Bug#5984).
12556 2011-08-07 Juri Linkov <juri@jurta.org>
12558 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
12559 to show the arg `TIME' instead of `TIMEVAL'.
12561 2011-08-06 Eli Zaretskii <eliz@gnu.org>
12563 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
12564 display property strides EOL and includes a newline, as in
12565 longlines-mode. (Bug#9254)
12566 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
12567 word-wrap under bidirectional display. (Bug#9224)
12569 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
12570 is non-zero, even if the data buffer is NULL. Fixes a crash in
12571 vertical-motion with longlines-mode. (Bug#9254)
12573 2011-08-05 Eli Zaretskii <eliz@gnu.org>
12575 * bidi.c <bidi_cache_total_alloc>: Now static.
12576 (bidi_initialize): Initialize bidi_cache_total_alloc.
12578 * xdisp.c (display_line): Release buffer allocated for shelved bidi
12581 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
12582 amount allocated this far in `bidi_cache_total_alloc'.
12583 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
12584 non-zero, only free the data buffer without restoring the cache
12585 contents. All callers changed.
12587 * dispextern.h (bidi_unshelve_cache): Update prototype.
12589 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
12590 (move_it_in_display_line, move_it_to)
12591 (move_it_vertically_backward, move_it_by_lines): Replace the call
12592 to xfree to an equivalent call to bidi_unshelve_cache.
12593 (move_it_in_display_line_to): Fix logic of returning
12594 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
12596 2011-08-05 Eli Zaretskii <eliz@gnu.org>
12598 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
12599 came from a string character with a `cursor' property. (Bug#9229)
12601 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
12603 * Makefile.in (LIB_PTHREAD): New variable.
12604 (LIBES): Add LIB_PTHREAD (Bug#9216).
12606 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
12607 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
12609 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
12611 * regex.c (re_iswctype): Remove some redundant boolean conversions.
12613 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
12615 * xterm.c (x_find_topmost_parent): New function.
12616 (x_set_frame_alpha): Find topmost parent window with
12617 x_find_topmost_parent and set the property there also (bug#9181).
12618 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
12620 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
12622 * callproc.c (Fcall_process): Avoid vfork clobbering
12623 the local vars buffer, coding_systems, current_dir.
12625 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
12627 * keymap.c (Fmake_composed_keymap): Move to subr.el.
12629 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
12631 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
12632 so that it is not optimized away.
12634 * xdisp.c (compute_display_string_pos): Remove unused local.
12636 2011-08-02 Eli Zaretskii <eliz@gnu.org>
12638 Fix slow cursor motion and scrolling in large buffers with
12639 selective display, like Org Mode buffers. (Bug#9218)
12641 * dispextern.h (struct bidi_it): New member disp_prop_p.
12643 * xdisp.c: Remove one-slot cache of display string positions.
12644 (compute_display_string_pos): Accept an additional argument
12645 DISP_PROP_P; callers changed. Scan at most 5K characters forward
12646 for a display string or property. If found, set DISP_PROP_P
12649 * bidi.c (bidi_fetch_char): Accept an additional argument
12650 DISP_PROP_P, and pass it to compute_display_string_pos.
12651 Only handle text covered by a display string if DISP_PROP_P is returned
12652 non-zero. All callers of bidi_fetch_char changed.
12654 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
12656 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
12658 2010-12-03 Don March <don@ohspite.net>
12660 * keymap.c (Fdefine_key): Fix non-prefix key error message when
12661 last character M-[char] is translated to ESC [char] (bug#7541).
12663 2011-08-02 Kenichi Handa <handa@m17n.org>
12665 * lisp.h (uniprop_table): Extern it.
12667 * chartab.c (uniprop_table): Make it non-static.
12669 2011-08-01 Eli Zaretskii <eliz@gnu.org>
12671 * xdisp.c (forward_to_next_line_start): Accept additional argument
12672 BIDI_IT_PREV, and store into it the state of the bidi iterator had
12674 (reseat_at_next_visible_line_start): Use the bidi iterator state
12675 returned by forward_to_next_line_start to restore the state of
12676 it->bidi_it after backing up to previous newline. (Bug#9212)
12678 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
12680 * regex.c (re_comp): Protoize.
12681 (re_exec): Fix return type.
12682 (regexec): Fix type of `ret'. (Bug#9203)
12684 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
12686 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
12687 This is needed if max-image-size is a floating-point number.
12689 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
12691 * print.c (print_object): Print empty symbol as ##.
12693 * lread.c (read1): Read ## as empty symbol.
12695 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
12697 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
12698 setting frame foreground color (Bug#9175).
12699 (x_set_background_color): Likewise.
12701 * nsmenu.m (-setText): Size tooltip dimensions precisely to
12702 contents (Bug#9176).
12703 (EmacsTooltip -init): Remove bezels and add shadows to
12706 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
12707 or scroll bar (Bug#8470).
12709 * nsfont.m (nsfont_open): Remove assignment to voffset and
12710 unnecessary vars hshink, expand, hd, full_height, min_height.
12711 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
12713 * nsterm.h (nsfont_info): Remove voffset field.
12715 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
12717 Implement strike-through and overline on NextStep (Bug#8863).
12719 * nsfont.m (nsfont_open): Use underline position provided by font,
12720 instead of hard-coded value of 2.
12721 (nsfont_draw): Call ns_draw_text_decoration instead.
12723 * nsterm.h: Add declaration for ns_draw_text_decoration.
12725 * nsterm.m (ns_draw_text_decoration): New function for drawing
12726 underline, overline, and strike-through.
12727 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
12728 ns_draw_text_decoration. Change treatment of cursor drawing to
12729 accommodate underlining, etc.
12731 2011-07-28 Eli Zaretskii <eliz@gnu.org>
12733 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
12736 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
12738 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
12739 Without this fix, if a signal arrives just after memory fills up,
12740 'malloc' might be invoked reentrantly.
12742 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
12743 In other words, assume that every image size is allowed, on non-X
12744 hosts. This assumption is probably wrong, but it lets Emacs compile.
12746 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
12748 * regex.c (re_iswctype): Convert return values to boolean.
12750 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
12752 * xdisp.c (compute_display_string_pos): Don't use cached display
12753 string position if the buffer had its restriction changed.
12756 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
12758 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
12760 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
12762 Integer signedness and overflow and related fixes. (Bug#9079)
12764 * bidi.c: Integer size and overflow fixes.
12765 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
12766 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
12767 (bidi_cache_find_level_change, bidi_cache_ensure_space)
12768 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
12769 (bidi_find_other_level_edge):
12770 Use ptrdiff_t instead of EMACS_INT where either will do.
12771 This works better on 32-bit hosts configured --with-wide-int.
12772 (bidi_cache_ensure_space): Check for size-calculation overflow.
12773 Use % rather than repeated addition, for better worst-case speed.
12774 Don't set bidi_cache_size until after xrealloc returns, because it
12776 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
12777 (bidi_cache_ensure_space): Also check that the bidi cache size
12778 does not exceed that of the largest Lisp string or buffer. See Eli
12779 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
12781 * alloc.c (__malloc_size_t): Remove.
12782 All uses replaced by size_t. See Andreas Schwab's note
12783 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
12785 * image.c: Improve checking for integer overflow.
12786 (check_image_size): Assume that f is nonnull, since
12787 it is always nonnull in practice. This is one less thing to
12788 worry about when checking for integer overflow later.
12789 (x_check_image_size): New function, which checks for integer
12790 overflow issues inside X.
12791 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
12792 This removes the need for a memory_full check.
12793 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
12794 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
12795 (xbm_read_bitmap_data): Change locals back to 'int', since
12796 their values must fit in 'int'.
12797 (xpm_load_image, png_load, tiff_load):
12798 Invoke x_create_x_image_and_pixmap earlier,
12799 to avoid much needless work if the image is too large.
12800 (tiff_load): Treat overly large images as if
12801 x_create_x_image_and_pixmap failed, not as malloc failures.
12802 (gs_load): Use x_check_image_size.
12804 * gtkutil.c: Omit integer casts.
12805 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
12806 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
12808 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
12810 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
12811 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
12812 would wrongly return t on a 64-bit host.
12814 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
12815 The plain *_OVERFLOW macros run afoul of GCC bug 49705
12816 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
12817 and therefore cause GCC to emit a bogus diagnostic in some cases.
12819 * image.c: Integer signedness and overflow and related fixes.
12820 This is not an exhaustive set of fixes, but it's time to
12821 record what I've got.
12822 (lookup_pixel_color, check_image_size): Remove redundant decls.
12823 (check_image_size): Don't assume that arbitrary EMACS_INT values
12824 fit in 'int', or that arbitrary 'double' values fit in 'int'.
12825 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
12826 (tiff_load, imagemagick_load_image):
12827 Check for overflow in size calculations.
12828 (x_create_x_image_and_pixmap): Remove unnecessary test for
12829 xmalloc returning NULL; that can't happen.
12830 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
12831 (xpm_color_bucket): Use better integer hashing function.
12832 (xpm_cache_color): Don't possibly over-allocate memory.
12833 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
12834 (gif_memory_source):
12835 Use ptrdiff_t, not int or size_t, to record sizes.
12836 (png_load): Don't assume values greater than 2**31 fit in 'int'.
12837 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
12838 either works, as we prefer signed integers.
12839 (tiff_read_from_memory, tiff_write_from_memory):
12840 Return tsize_t, not size_t, since that's what the TIFF API wants.
12841 (tiff_read_from_memory): Don't fail simply because the read would
12842 go past EOF; instead, return a short read.
12843 (tiff_load): Omit no-longer-needed casts.
12844 (Fimagemagick_types): Don't assume size fits into 'int'.
12846 Improve hashing quality when configured --with-wide-int.
12847 * fns.c (hash_string): New function, taken from sxhash_string.
12848 Do not discard information about ASCII character case; this
12849 discarding is no longer needed.
12850 (sxhash-string): Use it. Change sig to match it. Caller changed.
12851 * lisp.h: Declare it.
12852 * lread.c (hash_string): Remove, since we now use fns.c's version.
12853 The fns.c version returns a wider integer if --with-wide-int is
12854 specified, so this should help the quality of the hashing a bit.
12856 * emacs.c: Integer overflow minor fix.
12857 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
12858 Define only if GNU_LINUX.
12859 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
12861 * dispnew.c: Integer signedness and overflow fixes.
12862 Remove unnecessary forward decls, that were a maintenance hassle.
12863 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
12865 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
12866 (scrolling_window): Use ptrdiff_t, not int, for byte count.
12867 (prepare_desired_row, line_draw_cost):
12868 Use int, not unsigned, where either works.
12869 (save_current_matrix, restore_current_matrix):
12870 Use ptrdiff_t, not size_t, where either works.
12871 (init_display): Check for overflow more accurately, and without
12872 relying on undefined behavior.
12874 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
12875 Remove, replacing with the new symbols in lisp.h. All uses changed.
12876 * fileio.c (make_temp_name):
12877 * filelock.c (lock_file_1, lock_file):
12878 * xdisp.c (message_dolog):
12879 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
12880 Use pMd etc. instead.
12881 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
12882 replacing the pWIDE etc. symbols removed from editfns.c.
12884 * keyboard.h (num_input_events): Now uintmax_t.
12885 This is (very slightly) less likely to mess up due to wraparound.
12888 * buffer.c: Integer signedness fixes.
12889 (alloc_buffer_text, enlarge_buffer_text):
12890 Use ptrdiff_t rather than size_t when either will do, as we prefer
12893 * alloc.c: Integer signedness and overflow fixes.
12894 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
12895 (__malloc_size_t): Default to size_t, not to int.
12896 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
12897 (Fgarbage_collect, mark_object_loop_halt, mark_object):
12898 Prefer ptrdiff_t to size_t when either would do, as we prefer
12900 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
12901 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
12902 Now const. Initialize with values that are in range even if char
12904 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
12905 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
12906 These functions do the right thing with sizes > 2**32.
12907 (check_depth): Now ptrdiff_t, not int.
12908 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
12909 Adjust to new way of storing sizes. Check for size overflow bugs
12911 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
12912 slightly wrong anyway, as it missed one instance of
12913 XMALLOC_OVERRUN_CHECK_OVERHEAD.
12914 (refill_memory_reserve): Omit needless cast to size_t.
12915 (mark_object_loop_halt): Mark as externally visible.
12917 * xselect.c: Integer signedness and overflow fixes.
12918 (Fx_register_dnd_atom, x_handle_dnd_message):
12919 Use ptrdiff_t, not size_t, since we prefer signed.
12920 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
12921 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
12922 x_dnd_atoms_size and x_dnd_atoms_length.
12924 * doprnt.c: Prefer signed to unsigned when either works.
12926 * doprnt.c (doprnt):
12928 * xdisp.c (vmessage):
12929 Use ptrdiff_t, not size_t, when using or implementing doprnt,
12930 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
12931 prefer signed arithmetic to avoid comparison confusion.
12932 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
12933 but is a bit tricky.
12935 Assume freestanding C89 headers, string.h, stdlib.h.
12936 * data.c, doprnt.c, floatfns.c, print.c:
12937 Include float.h unconditionally.
12938 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
12939 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
12940 * regex.c: Likewise for stddef.h, string.h.
12941 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
12942 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
12943 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
12944 (STDC_HEADERS): Remove obsolete defines.
12945 * sysdep.c: Include limits.h unconditionally.
12947 Assume support for memcmp, memcpy, memmove, memset.
12948 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
12949 * regex.c (memcmp, memcpy):
12950 Remove; we assume C89 now.
12952 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
12953 (__malloc_safe_bcopy): Remove; no longer needed.
12955 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
12956 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
12957 well either way, and we prefer signed to unsigned.
12959 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
12961 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
12962 closes the connection while we're reading (bug#9182).
12964 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
12966 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
12967 are specified (Bug#9168).
12969 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
12971 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
12972 Found by GCC static checking and --with-wide-int on a 32-bit host.
12974 2011-07-25 Eli Zaretskii <eliz@gnu.org>
12976 * xdisp.c (compute_display_string_pos): Fix logic of caching
12977 previous display string position. Initialize cached_prev_pos to
12978 -1. Fixes slow-down at the beginning of a buffer.
12980 2011-07-24 Eli Zaretskii <eliz@gnu.org>
12982 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
12983 for attrs[LFACE_FONTSET_INDEX].
12985 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
12987 * xml.c (parse_region): Remove unused local
12988 that was recently introduced.
12990 2011-07-23 Eli Zaretskii <eliz@gnu.org>
12992 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
12993 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
12995 * xdisp.c (move_it_in_display_line_to): Record the best matching
12996 position for TO_CHARPOS while scanning the line, and restore it on
12997 exit if none of the characters scanned was an exact match.
12998 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
12999 when exact match is impossible due to invisible text, and the
13000 lines are truncated.
13002 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
13004 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
13007 2011-07-22 Eli Zaretskii <eliz@gnu.org>
13009 Fix a significant slow-down of cursor motion with C-n, C-p,
13010 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
13011 auto-repeat under bidi redisplay in fontified buffers.
13012 * xdisp.c (compute_stop_pos_backwards): New function.
13013 (next_element_from_buffer): Call compute_stop_pos_backwards to
13014 find a suitable prev_stop when we find ourselves before
13016 (reseat): Don't look for prev_stop, as that could mean a very long
13018 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
13019 <cached_disp_overlay_modiff>: Cache for last found display string
13021 (compute_display_string_pos): Return the cached position if asked
13022 about the same buffer in the same area of character positions, and
13023 the buffer wasn't changed since the time the display string
13024 position was cached.
13026 2011-07-22 Eli Zaretskii <eliz@gnu.org>
13028 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
13029 is an integer, which is important for empty lines. (Bug#9149)
13031 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
13033 * frame.c (Fmodify_frame_parameters): In tty case, update the
13034 default face if necessary (Bug#4238).
13036 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
13038 * editfns.c (Fstring_to_char): No need to explain what a character
13039 is in the docstring (Bug#6576).
13041 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
13043 * xml.c (parse_region): Make sure we always return a tree.
13045 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
13047 * xml.c (parse_region): If a document contains only comments,
13050 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
13052 * xml.c (make_dom): Return comments, too.
13054 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
13057 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
13058 and the surrounding thread.
13059 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
13060 rather than fgets, and retry after EINTR. Otherwise, 'emacs
13061 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
13063 * s/openbsd.h (BROKEN_SIGIO): Define.
13064 * unexelf.c (unexec) [__OpenBSD__]:
13065 Don't update the .mdebug section of the Alpha COFF symbol table.
13067 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
13069 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
13072 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
13074 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
13075 This fixes some race conditions on the permissions of any newly
13078 * alloc.c (valid_pointer_p): Use pipe, not open.
13079 This fixes some permissions issues when debugging.
13081 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
13082 If fchown fails to set both uid and gid, try to set just gid,
13083 as that is sometimes allowed. Adjust the file's mode to eliminate
13084 setuid or setgid bits that are inappropriate if fchown fails.
13086 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
13088 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ

13094 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
13096 * lread.c (read_integer): Unread even EOF character.
13097 (read1): Likewise. Properly record start position of symbol.

13100 symbol character follows.
13102 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
13104 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
13105 This works around a problem with the previous change to Fcopy_file.
13106 Recent glibc declares fchown with __attribute__((warn_unused_result)),
13107 and without this change, GCC might complain about discarding
13108 fchown's return value.
13110 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
13112 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
13114 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
13116 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
13118 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
13120 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
13121 it's used from the C level.
13123 * process.c: Use the same condition for POLL_FOR_INPUT in both
13124 keyboard.c and process.c (bug#1858).
13126 2011-07-09 Lawrence Mitchell <wence@gmx.li>
13128 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
13129 (Fgnutls_boot): Use it.
13131 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
13133 * doc.c (Fsubstitute_command_keys): Revert last change.
13135 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
13137 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
13138 quotes the next character, and doesn't affect other longer
13139 sequences (bug#8935).
13141 * lread.c (syms_of_lread): Clarify that is isn't only
13142 `eval-buffer' and `eval-defun' that's affected by
13143 `lexical-binding' (bug#8460).
13145 2011-07-15 Eli Zaretskii <eliz@gnu.org>
13147 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
13148 bidi redisplay when a line includes both an image and is truncated.
13150 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
13152 Fix minor problems found by static checking.
13153 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
13154 (elsz): Now a signed constant, not a size_t var. We prefer signed
13155 types to unsigned, to avoid integer comparison confusion. Without
13156 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
13157 "cannot optimize loop, the loop counter may overflow", a symptom
13159 * indent.c (Fvertical_motion): Mark locals as initialized.
13160 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
13162 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>

13185 buffer position was specified. Initialize paragraph_embedding to
13187 (reseat_to_string): Initialize the bidi iterator.
13188 (display_string): If we need to ignore text properties of
13189 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
13190 original value of -1 will not work with bidi.)
13191 (compute_display_string_pos): First arg is now struct
13192 `text_pos *'; all callers changed. Support display properties on
13194 (compute_display_string_end): Support display properties on Lisp
13196 (init_iterator, reseat_1, reseat_to_string): Initialize the
13197 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
13198 when iterating on a string not from display properties).

13200 Fix calculation of the object to scan. Fixes an error when using
13202 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
13203 base_level_stop; instead, set base_level_stop to BEGV.
13204 Fixes crashes in vertical-motion.
13205 (next_element_from_buffer): Improve commentary for when
13206 the iterator is before prev_stop.
13207 (init_iterator): Initialize bidi_p from the default value of
13208 bidi-display-reordering, not from buffer-local value. Use the
13209 buffer-local value only if initializing for buffer iteration.

13230 parts of next_element_from_buffer, next_element_from_string, and
13231 next_element_from_c_string.

13243 (get_overlay_strings_1, push_display_prop): Set up the bidi
13244 iterator for displaying display or overlay strings.
13245 (forward_to_next_line_start): Don't use the shortcut if
13247 (back_to_previous_visible_line_start): If handle_display_prop
13248 pushed the iterator stack, restore the internal state of the bidi
13249 iterator by calling bidi_pop_it same number of times.
13250 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
13251 and we are bidi-iterating, don't decrement the iterator position;
13252 instead, set the first_elt flag in the bidi iterator, to produce
13254 (reseat_1): Remove redundant setting of string_from_display_prop_p.
13255 (push_display_prop): xassert that we are iterating a buffer.
13256 (push_it, pop_it): Save and restore paragraph_embedding member.
13257 (handle_single_display_spec, next_overlay_string)
13258 (get_overlay_strings_1, reseat_1, reseat_to_string)
13259 (push_display_prop): Set up the `unibyte' member of bidi_it.string
13260 correctly. Don't assume unibyte strings are not bidi-reordered.

13269 property. Fix a typo in popping stretch info. Add an assertion
13270 for verifying that the iterator position is in sync with the bidi
13272 (handle_single_display_spec, get_overlay_strings_1)

13297 displayed in margins. (Bug#8133) (Bug#8867)
13298 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past

13326 changed to -1 and -2, respectively.
13327 (bidi_char_at_pos): New function.
13328 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak):

13417 The old code sometimes used this field without initializing it.
13419 * alloc.c (gc_sweep): Don't read past end of array.
13420 In theory, the old code could also have corrupted Emacs internals,
13421 though it'd be very unlikely.

13525 sigprocmask is portable only for single-threaded applications, and

13688 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):

13726 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
13727 subseconds part to the entropy, as that's a bit more random.
13728 Prefer signed to unsigned, since the signedness doesn't matter and
13729 in general we prefer signed. When given a limit, use a
13730 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
13731 latter isn't right if USE_2_TAGS_FOR_INTS.
13732 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
13733 not 0..VALMASK. Don't discard "excess" bits that random () returns.

13745 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
13746 This is more efficient than Ffile_directory_p and avoids a minor race.

13750 * buffer.c (Foverlay_put): Say what the return value is
13753 * fileio.c (barf_or_query_if_file_exists): Check first if the file

13757 error be more correct.
13759 * fns.c (Frequire): Remove the mention of the .gz files, since

13776 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
13777 Also (re)move comments that are misplaced or no longer relevant.

13806 * lread.c (syms_of_lread): Mention single symbols defined by

13862 (something_changedCB): HAVE_GCONF: Call store_monospaced_changed
13863 with value as argument.
13864 (init_gsettings): Check that GSETTINGS_SCHEMA exists before calling
13865 g_settings_new (Bug#8967). Do not create gsettings_obj.

13873 (wait_reading_process_output): Add defined (HAVE_GSETTINGS) for
13876 2011-07-01 Paul Eggert <eggert@cs.ucla.edu>
13878 * eval.c (struct backtrace): Simplify and port the data structure.
13879 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
13880 signed bit field, as this assumption is not portable and it makes
13881 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
13882 "char debug_on_exit : 1" as this is not portable either; instead,
13883 use the portable "unsigned int debug_on_exit : 1". Remove unused
13884 member evalargs. Remove obsolete comments about cc bombing out.
13886 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>
13888 * xsettings.c: Include glib-object.h, gio/gio.h if HAVE_GSETTINGS.

13954 (emacs_fixed_new): Set priv->f to argument.
13955 (emacs_fixed_get_preferred_width)
13956 (emacs_fixed_get_preferred_height): Use min_width/height from
13957 frames size_hint to set minimum and natural (Bug#8919).
13958 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
13959 and use min_width/height from frames size_hint to set
13960 min_width/height (Bug#8919).

13980 Use gnulib's dup2 module instead of rolling our own.
13981 * sysdep.c (dup2) [!HAVE_DUP2]: Remove; gnulib now does this.
13983 2011-06-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
13985 * dispnew.c (scrolling_window): Before scrolling, turn off a

14048 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
14050 Integer and buffer overflow fixes (Bug#8873).
14052 * print.c (printchar, strout): Check for string overflow.
14053 (PRINTPREPARE, printchar, strout):
14054 Don't set size unless allocation succeeds.
14056 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
14057 for sizes. Check for string overflow more accurately.
14058 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
14060 * macros.c: Integer and buffer overflow fixes.
14061 * keyboard.h (struct keyboard.kbd_macro_bufsize):
14062 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

14065 Check for size-calculation overflow.
14066 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
14068 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
14070 * lread.c: Integer overflow fixes.
14071 (read_integer): Radix is now EMACS_INT, not int,
14072 to improve quality of diagnostics for out-of-range radices.
14073 Calculate buffer size correctly for out-of-range radices.
14074 (read1): Check for integer overflow in radices, and in
14075 read-circle numbers.
14076 (read_escape): Avoid int overflow.
14077 (Fload, openp, read_buffer_size, read1)
14078 (substitute_object_recurse, read_vector, read_list, map_obarray):
14079 Use ptrdiff_t, not int, for sizes.

14094 2011-06-22 Leo Liu <sdl.web@gmail.com>
14096 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
14097 Move to minibuffer.el.
14099 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
14101 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
14102 The following patches are for when GLYPH_DEBUG && !XASSERT.
14103 * dispextern.h (trace_redisplay_p, dump_glyph_string):
14104 * dispnew.c (flush_stdout):
14105 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
14106 Mark as externally visible.
14107 * dispnew.c (check_window_matrix_pointers): Now static.
14108 * dispnew.c (window_to_frame_vpos):
14109 * xfns.c (unwind_create_frame):
14110 * xterm.c (x_check_font): Remove unused local.
14111 * scroll.c (CHECK_BOUNDS):
14112 * xfaces.c (cache_fache): Rename local to avoid shadowing.
14113 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
14114 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
14115 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
14116 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
14118 (debug_method_add): Use va_list and vsprintf rather than relying
14119 on undefined behavior with wrong number of arguments.
14120 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
14121 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
14122 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
14123 since we're not interested in debugging glyphs with old libraries.
14124 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
14125 GCC 4.6.0's static checking.
14127 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
14129 Integer overflow and signedness fixes (Bug#8873).

14139 (x_create_bitmap_from_xpm_data):
14140 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
14141 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
14143 * xfaces.c (load_pixmap):
14144 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
14145 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
14146 (.bitmaps_last, struct x_output.icon_bitmap):
14147 Use ptrdiff_t, not int, for bitmap indexes.
14148 (x_allocate_bitmap_record): Check for size overflow.
14149 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
14151 Use ptrdiff_t, not int, for overlay counts.
14152 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
14153 * editfns.c (overlays_around, get_pos_property):
14154 * textprop.c (get_char_property_and_overlay):
14155 * xdisp.c (next_overlay_change, note_mouse_highlight):
14156 * xfaces.c (face_at_buffer_position):
14157 * buffer.c (OVERLAY_COUNT_MAX): New macro.
14158 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
14159 (Fnext_overlay_change, Fprevious_overlay_change)
14160 (mouse_face_overlay_overlaps, Foverlays_in):
14161 Use ptrdiff_t, not int, for sizes.
14162 (overlays_at, overlays_in): Check for size-calculation overflow.
14164 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
14166 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
14167 (x_session_initialize): Do not assume string length fits in int.
14169 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
14170 This is unlikely, but can occur if DPI is outlandish.
14172 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
14173 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
14175 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
14176 * xrdb.c (magic_file_p, search_magic_path):
14177 Omit last arg SUFFIX; it was always 0. All callers changed.
14178 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
14180 * xfont.c (xfont_match): Avoid need for strlen.
14182 * xfns.c: Don't assume strlen fits in int.
14183 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
14185 * xdisp.c (message_log_check_duplicate): Return intmax_t,
14186 not unsigned long, as we prefer signed integers. All callers changed.
14187 Detect integer overflow in repeat count.
14188 (message_dolog): Don't assume print length fits in 39 bytes.
14189 (display_mode_element): Don't assume strlen fits in int.
14191 * termcap.c: Don't assume sizes fit in int and never overflow.
14192 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
14193 (gobble_line): Check for size-calculation overflow.
14195 * minibuf.c (Fread_buffer):
14196 * lread.c (intern, intern_c_string):
14197 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
14198 Don't assume string length fits in int.

14207 Don't assume integer property fits in fixnum.
14208 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
14210 * filelock.c: Fix some buffer overrun and integer overflow issues.
14211 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
14212 Reformulate so as not to need the command string.
14213 Invoke gzip -cd rather than gunzip, as it's more portable.
14214 (lock_info_type, lock_file_1, lock_file):
14215 Don't assume pid_t and time_t fit in unsigned long.
14216 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
14217 (current_lock_owner): Prefer signed type for sizes.
14218 Use memcpy, not strncpy, where memcpy is what is really wanted.
14219 Don't assume (via atoi) that time_t and pid_t fit in int.
14220 Check for time_t and/or pid_t out of range, e.g., via a network share.
14221 Don't alloca where an auto var works fine.
14223 * fileio.c: Fix some integer overflow issues.
14224 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
14225 Don't assume string length fits in int.
14226 (directory_file_name): Don't assume string length fits in long.
14227 (make_temp_name): Don't assume pid fits in int, or that its print
14228 length is less than 20.
14230 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
14232 * coding.c (make_subsidiaries): Don't assume string length fits in int.
14234 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
14236 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
14237 We prefer signed integers, even for size calculations.
14239 * emacs.c: Don't assume string length fits in 'int'.
14240 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
14241 (main): Don't invoke strlen when not needed.

14246 * callproc.c (getenv_internal_1, getenv_internal)
14247 (Fgetenv_internal):
14248 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
14250 * lread.c (invalid_syntax): Omit length argument.
14251 All uses changed. This doesn't fix a bug, but it simplifies the
14252 code away from its former Hollerith-constant appearance, and it's
14253 one less 'int' to worry about when looking at integer-overflow issues.
14254 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
14256 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
14257 This didn't break anything, but it didn't help either.
14258 It's confusing to put a bogus integer in a place where the actual
14259 value does not matter.
14260 (LIST_END_P): Remove unused macro and its bogus comment.
14261 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
14263 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
14264 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
14266 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
14267 We prefer signed types, and the value cannot exceed the EMACS_INT
14268 range anyway (because otherwise the length would not be representable).
14269 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
14270 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
14271 This avoids a GCC warning when WIDE_EMACS_INT.
14273 * indent.c (sane_tab_width): New function.
14274 (current_column, scan_for_column, Findent_to, position_indentation)
14275 (compute_motion): Use it. This is just for clarity.
14276 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
14278 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
14280 * lisp.h (lint_assume): New macro.
14281 * composite.c (composition_gstring_put_cache):
14282 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
14284 * editfns.c, insdel.c:
14285 Omit unnecessary forward decls, to simplify future changes.
14287 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
14289 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
14291 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
14292 Use much-faster test for byte-length change.
14293 Don't assume string byte-length fits in 'int'.
14294 Check that character arg fits in 'int'.
14295 (mapcar1): Declare byte as byte, for clarity.
14297 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
14299 * fns.c (concat): Catch string overflow earlier.
14300 Do not rely on integer wraparound.
14302 * dispextern.h (struct it.overlay_strings_charpos)
14303 (struct it.selective): Now EMACS_INT, not int.
14304 * xdisp.c (forward_to_next_line_start)
14305 (back_to_previous_visible_line_start)
14306 (reseat_at_next_visible_line_start, next_element_from_buffer):
14307 Don't arbitrarily truncate the value of 'selective' to int.
14309 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
14311 * composite.c: Don't truncate sizes to 'int'.
14312 (composition_gstring_p, composition_reseat_it)
14313 (composition_adjust_point): Use EMACS_INT, not int.
14314 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
14315 not EMACS_UINT, for indexes.
14317 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
14319 * buffer.c: Include <verify.h>.
14320 (struct sortvec.priority, struct sortstr.priority):
14321 Now EMACS_INT, not int.
14322 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
14323 (struct sortstr.size, record_overlay_string)
14324 (struct sortstrlist.size, struct sortlist.used):
14325 Don't truncate size to int.
14326 (record_overlay_string): Check for size-calculation overflow.
14327 (init_buffer_once): Check at compile-time, not run-time.
14329 2011-06-22 Jim Meyering <meyering@redhat.com>
14331 Don't leak an XBM-image-sized buffer
14332 * image.c (xbm_load): Free the image buffer after using it.
14334 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
14337 * composite.c (find_automatic_composition): Omit needless 'return 0;'
14338 that Sun C diagnosed.
14339 * fns.c (secure_hash): Fix pointer signedness issue.
14340 * intervals.c (static_offset_intervals): New function.
14341 (offset_intervals): Use it.
14343 2011-06-21 Leo Liu <sdl.web@gmail.com>
14346 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
14349 * fns.c (secure_hash): Rename from crypto_hash_function and change
14350 the first arg to accept symbols.
14351 (Fsecure_hash): New primitive.
14352 (syms_of_fns): New symbols.
14354 2011-06-20 Deniz Dogan <deniz@dogan.se>
14356 * process.c (Fset_process_buffer): Clarify return value in
14359 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
14361 * dispnew.c (add_window_display_history): Use BVAR.
14363 * xdisp.c (debug_method_add): Use BVAR.
14364 (check_window_end, dump_glyph_matrix, dump_glyph)
14365 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
14367 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
14370 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
14371 check till after the cache is created in init_frame_faces.
14373 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
14375 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
14377 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
14379 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
14380 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
14381 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
14383 Improve buffer-overflow checking (Bug#8873).
14384 * fileio.c (Finsert_file_contents):
14385 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
14386 Remove the old (too-loose) buffer overflow checks.
14387 They weren't needed, since make_gap checks for buffer overflow.
14388 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
14389 The old code merely checked for Emacs fixnum overflow, and relied
14390 on undefined (wraparound) behavior. The new code avoids undefined
14391 behavior, and also checks for ptrdiff_t and/or size_t overflow.
14393 * editfns.c (Finsert_char): Don't dump core with very negative counts.
14394 Tune. Don't use wider integers than needed. Don't use alloca.
14395 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
14397 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
14399 * insdel.c, lisp.h (buffer_overflow): New function.
14400 (insert_from_buffer_1, replace_range, replace_range_2):
14401 * insdel.c (make_gap_larger):
14402 * editfns.c (Finsert_char):
14403 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
14405 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
14407 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
14409 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
14411 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
14412 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
14414 * fileio.c: Don't assume EMACS_INT fits in off_t.
14415 (emacs_lseek): New static function.
14416 (Finsert_file_contents, Fwrite_region): Use it.
14417 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
14419 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
14421 * fns.c: Don't overflow int when computing a list length.
14422 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
14423 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
14424 truncation on 64-bit hosts. Check for QUIT every
14425 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
14426 faster and is responsive enough.
14427 (Flength): Report an error instead of overflowing an integer.
14428 (Fsafe_length): Return a float if the value is not representable
14429 as a fixnum. This shouldn't happen except in contrived situations.
14430 (Fnthcdr, Fsort): Don't assume list length fits in int.
14431 (Fcopy_sequence): Don't assume vector length fits in int.
14433 * alloc.c: Check that resized vectors' lengths fit in fixnums.
14434 (header_size, word_size): New constants.
14435 (allocate_vectorlike): Don't check size overflow here.
14436 (allocate_vector): Check it here instead, since this is the only
14437 caller of allocate_vectorlike that could cause overflow.
14438 Check that the new vector's length is representable as a fixnum.
14440 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
14441 The previous code was bogus. For example, next_almost_prime (32)
14442 returned 39, which is undesirable as it is a multiple of 3; and
14443 next_almost_prime (24) returned 25, which is a multiple of 5 so
14444 why was the code bothering to check for multiples of 7?
14446 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
14448 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
14450 Variadic C functions now count arguments with ptrdiff_t.
14451 This partly undoes my 2011-03-30 change, which replaced int with size_t.
14452 Back then I didn't know that the Emacs coding style prefers signed int.
14453 Also, in the meantime I found a few more instances where arguments
14454 were being counted with int, which may truncate counts on 64-bit
14455 machines, or EMACS_INT, which may be unnecessarily wide.
14456 * lisp.h (struct Lisp_Subr.function.aMANY)
14457 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
14458 Arg counts are now ptrdiff_t, not size_t.
14459 All variadic functions and their callers changed accordingly.
14460 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
14461 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
14462 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
14463 * callint.c (Fcall_interactively): Check arg count for overflow,
14464 to avoid potential buffer overrun. Use signed char, not 'int',
14465 for 'varies' array, so that we needn't bother to check its size
14466 calculation for overflow.
14467 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
14468 * eval.c (apply_lambda):
14469 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
14470 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
14471 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
14473 * callint.c (Fcall_interactively): Don't use index var as event count.
14475 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
14476 * mem-limits.h (SIZE): Remove; no longer used.
14478 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
14480 Remove unnecessary casts.
14481 * xterm.c (x_term_init):
14482 * xfns.c (x_set_border_pixel):
14483 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
14484 These aren't needed now that we assume ANSI C.
14486 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
14487 It's more likely to cause problems (due to unsigned overflow)
14490 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
14492 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
14494 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
14496 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
14498 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
14500 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
14502 GLYPH_CODE_FACE returns EMACS_INT, not int.
14503 * dispextern.h (merge_faces):
14504 * xfaces.c (merge_faces):
14505 * xdisp.c (get_next_display_element, next_element_from_display_vector):
14506 Don't assume EMACS_INT fits in int.
14508 * character.h (CHAR_VALID_P): Remove unused parameter.
14509 * fontset.c, lisp.h, xdisp.c: All uses changed.
14511 * editfns.c (Ftranslate_region_internal): Omit redundant test.
14513 * fns.c (concat): Minor tuning based on overflow analysis.
14514 This doesn't fix any bugs. Use int to hold character, instead
14515 of constantly refetching from Emacs object. Use XFASTINT, not
14516 XINT, for value known to be a character. Don't bother comparing
14517 a single byte to 0400, as it's always less.
14519 * floatfns.c (Fexpt):
14520 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
14522 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
14525 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
14527 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
14528 Without this fix, on a 64-bit host (aset S 0 4294967386) would
14529 incorrectly succeed when S was a string, because 4294967386 was
14530 truncated before it was used.
14532 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
14533 Otherwise, an out-of-range integer could cause undefined behavior
14536 * composite.c: Use int, not EMACS_INT, for characters.
14537 (fill_gstring_body, composition_compute_stop_pos): Use int, not
14538 EMACS_INT, for values that are known to be in character range.
14539 This doesn't fix any bugs but is the usual style inside Emacs and
14540 may generate better code on 32-bit machines.
14542 Make sure a 64-bit char is never passed to ENCODE_CHAR.
14543 This is for reasons similar to the recent CHAR_STRING fix.
14544 * charset.c (Fencode_char): Check that character arg is actually
14545 a character. Pass an int to ENCODE_CHAR.
14546 * charset.h (ENCODE_CHAR): Verify that the character argument is no
14547 wider than 'int', as a compile-time check to prevent future regressions
14550 * character.c (char_string): Remove unnecessary casts.
14552 Make sure a 64-bit char is never passed to CHAR_STRING.
14553 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
14554 by silently ignoring the top 32 bits, allowing some values
14555 that were far too large to be valid characters.
14556 * character.h: Include <verify.h>.
14557 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
14558 arguments are no wider than unsigned, as a compile-time check
14559 to prevent future regressions in this area.
14561 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
14562 (Fsubst_char_in_region):
14564 * xdisp.c (decode_mode_spec_coding):
14565 Adjust to CHAR_STRING's new requirement.
14566 * editfns.c (Finsert_char, Fsubst_char_in_region):
14567 * fns.c (concat): Check that character args are actually
14568 characters. Without this test, these functions did the wrong
14569 thing with wildly out-of-range values on 64-bit hosts.
14571 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
14572 These casts should not be needed on 32-bit hosts, either.
14573 * keyboard.c (read_char):
14574 * lread.c (Fload): Remove casts to unsigned.
14576 * lisp.h (UNSIGNED_CMP): New macro.
14577 This fixes comparison bugs on 64-bit hosts.
14578 (ASCII_CHAR_P): Use it.
14579 * casefiddle.c (casify_object):
14580 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
14581 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
14582 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
14583 * dispextern.h (FACE_FROM_ID):
14584 * keyboard.c (read_char): Use UNSIGNED_CMP.
14586 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
14587 not to EMACS_INT, to avoid GCC warning.
14589 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
14591 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
14592 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
14593 isn't needed on 32-bit machines.
14595 * buffer.c (Fgenerate_new_buffer_name):
14596 Use EMACS_INT for count, not int.
14597 (advance_to_char_boundary): Return EMACS_INT, not int.
14599 * data.c (Qcompiled_function): Now static.
14601 * window.c (window_body_lines): Now static.
14603 * image.c (gif_load): Rename local to avoid shadowing.
14605 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
14606 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
14607 * alloc.c (make_save_value): Integer argument is now of type
14608 ptrdiff_t, not int.
14609 (mark_object): Use ptrdiff_t, not int.
14610 * lisp.h (pD): New macro.
14611 * print.c (print_object): Use it.
14613 * alloc.c: Use EMACS_INT, not int, to count objects.
14614 (total_conses, total_markers, total_symbols, total_vector_size)
14615 (total_free_conses, total_free_markers, total_free_symbols)
14616 (total_free_floats, total_floats, total_free_intervals)
14617 (total_intervals, total_strings, total_free_strings):
14618 Now EMACS_INT, not int. All uses changed.
14619 (Fgarbage_collect): Compute overall total using a double, so that
14620 integer overflow is less likely to be a problem. Check for overflow
14621 when converting back to an integer.
14622 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
14623 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
14624 These were 'int' variables that could overflow on 64-bit hosts;
14625 they were never used, so remove them instead of repairing them.
14626 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
14627 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
14628 Previously, this ceilinged at INT_MAX, but that doesn't work on
14630 (allocate_pseudovector): Don't use EMACS_INT when int would do.
14632 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
14633 (allocate_vectorlike): Check for ptrdiff_t overflow.
14634 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
14635 when a (possibly-narrower) signed value would do just as well.
14636 We prefer using signed arithmetic, to avoid comparison confusion.
14638 * alloc.c: Catch some string size overflows that we were missing.
14639 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
14640 for convenience in STRING_BYTES_MAX.
14641 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
14642 The definition here is exact; the one in lisp.h was approximate.
14643 (allocate_string_data): Check for string overflow. This catches
14644 some instances we weren't catching before. Also, it catches
14645 size_t overflow on (unusual) hosts where SIZE_MAX <= min
14646 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
14647 and ptrdiff_t and EMACS_INT are both 64 bits.
14649 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
14650 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
14651 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
14653 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
14655 * alloc.c (Fmake_string): Check for out-of-range init.
14657 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
14659 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
14661 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
14663 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
14664 xg_get_default_scrollbar_width.
14666 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
14667 (int_gtk_range_get_value): Move to the scroll bar part of the file.
14668 (style_changed_cb): Call update_theme_scrollbar_width and call
14669 x_set_scroll_bar_default_width and xg_frame_set_char_size for
14670 all frames (Bug#8505).
14671 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
14672 Call gtk_window_set_resizable if HAVE_GTK3.
14673 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
14674 and height if HAVE_GTK3 (Bug#8505).
14675 (scroll_bar_width_for_theme): New variable.
14676 (update_theme_scrollbar_width): New function.
14677 (xg_get_default_scrollbar_width): Move code to
14678 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
14679 (xg_initialize): Call update_theme_scrollbar_width.
14681 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
14683 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
14685 2011-06-12 Martin Rudalics <rudalics@gmx.at>
14687 * frame.c (make_frame): Call other_buffer_safely instead of
14690 * window.c (temp_output_buffer_show): Call display_buffer with
14691 second argument Vtemp_buffer_show_specifiers and reset latter
14692 immediately after the call.
14693 (Vtemp_buffer_show_specifiers): New variable.
14694 (auto_window_vscroll_p, next_screen_context_lines)
14695 (Vscroll_preserve_screen_position): Remove leading asterisks from
14698 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
14700 Fix minor problems found by GCC 4.6.0 static checking.
14701 * buffer.c (Qclone_number): Remove for now, as it's unused.
14702 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
14703 (record_buffer): Remove unused local.
14704 * frame.c (other_visible_frames, frame_buffer_list): Now static.
14705 (set_frame_buffer_list): Remove; unused.
14706 * frame.h (other_visible_frames): Remove decl.
14707 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
14708 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
14709 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
14711 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
14712 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
14713 Define only if HAVE_GPM.
14714 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
14715 (update_hints_inhibit): Remove; never set. All uses removed.
14716 * widgetprv.h (emacsFrameClassRec): Remove decl.
14717 * window.c (delete_deletable_window): Now returns void, since it
14718 wasn't returning anything.
14719 (compare_window_configurations): Remove unused locals.
14720 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
14721 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
14722 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
14723 the same widths as pointers. This follows up on the 2011-05-06 patch.
14724 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
14725 * xterm.h: Likewise.
14726 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.
14728 2011-06-12 Juanma Barranquero <lekktu@gmail.com>
14730 * makefile.w32-in: Update dependencies.

15188 (x_clipboard_manager_error_1, x_clipboard_manager_error_2):
15189 New error handlers.
15190 (x_clipboard_manager_save_frame, x_clipboard_manager_save_all):
15191 Obey Vx_select_enable_clipboard_manager. Catch errors in
15192 x_clipboard_manager_save (Bug#8779).
15193 (Vx_select_enable_clipboard_manager): New variable.
15194 (x_get_foreign_selection): Reduce scope of x_catch_errors (Bug#8790).
15196 2011-06-04 Dan Nicolaescu <dann@ics.uci.edu>
15198 * emacs.c (main): Warn when starting a GTK emacs in daemon mode.
15200 2011-06-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15202 * fringe.c (update_window_fringes): Don't update overlay arrow bitmap
15203 in the current matrix if keep_current_p is non-zero.
15205 2011-06-04 Eli Zaretskii <eliz@gnu.org>
15207 * bidi.c (bidi_level_of_next_char): Fix last change.
15209 2011-06-03 Eli Zaretskii <eliz@gnu.org>
15211 Support bidi reordering of text covered by display properties.
15213 * bidi.c (bidi_copy_it): Use offsetof instead of emulating it.
15214 (bidi_fetch_char, bidi_fetch_char_advance): New functions.
15215 (bidi_cache_search, bidi_cache_iterator_state)
15216 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
15217 (bidi_level_of_next_char, bidi_move_to_visually_next):
15218 Support character positions inside a run of characters covered by a
15220 (bidi_paragraph_init, bidi_resolve_explicit_1)
15221 (bidi_level_of_next_char): Call bidi_fetch_char and
15222 bidi_fetch_char_advance instead of FETCH_CHAR and
15223 FETCH_CHAR_ADVANCE.
15224 (bidi_init_it): Initialize new members.
15225 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
15227 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
15228 instead of using explicit *_CHAR codes.
15229 (bidi_resolve_explicit, bidi_resolve_weak):
15230 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
15231 bidirectional text is supported only in multibyte buffers.
15232 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
15233 it to initialize the frame_window_p member of struct bidi_it.
15234 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
15235 (bidi_resolve_explicit, bidi_resolve_weak)
15236 (bidi_level_of_next_char, bidi_move_to_visually_next): Abort if
15237 bidi_it->nchars is non-positive.
15238 (bidi_level_of_next_char): Don't try to lookup the cache for the
15239 next/previous character if nothing is cached there yet, or if we
15240 were just reseat()'ed to a new position.
15242 * xdisp.c (set_cursor_from_row): Set start and stop points
15243 according to the row's direction when priming the loop that looks
15244 for the glyph on which to display cursor.
15245 (single_display_spec_intangible_p): Function deleted.
15246 (display_prop_intangible_p): Reimplement to call
15247 handle_display_spec instead of single_display_spec_intangible_p.
15248 Accept 3 additional arguments needed by handle_display_spec.
15249 This fixes incorrect cursor motion across display property with complex
15250 values: lists, `(when COND...)' forms, etc.
15251 (single_display_spec_string_p): Support property values that are
15252 lists with the argument STRING its top-level element.
15253 (display_prop_string_p): Fix the condition for processing a
15254 property that is a list to be consistent with handle_display_spec.
15255 (handle_display_spec): New function, refactored from the
15256 last portion of handle_display_prop.
15257 (compute_display_string_pos): Accept additional argument
15258 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
15259 value of a `display' property is a "replacing spec".
15260 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
15261 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
15262 the display property, but just return a value indicating whether
15263 the display property will replace the characters it covers.
15264 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
15265 frame_window_p members of struct bidi_it.
15266 (compute_display_string_pos, compute_display_string_end):
15268 (push_it): Accept second argument POSITION, where pop_it should
15269 jump to continue iteration.
15270 (reseat_1): Initialize bidi_it.disp_pos.
15272 * keyboard.c (adjust_point_for_property): Adjust the call to
15273 display_prop_intangible_p to its new signature.
15275 * dispextern.h (struct bidi_it): New member frame_window_p.
15276 (bidi_init_it): Update prototypes.
15277 (display_prop_intangible_p): Update prototype.
15278 (compute_display_string_pos, compute_display_string_end):
15279 Declare prototypes.
15280 (struct bidi_it): New members nchars and disp_pos. ch_len is now
15283 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
15285 Malloc failure behavior now depends on size of allocation.
15286 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
15287 * lisp.h: Change signatures accordingly.
15288 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
15289 All callers changed. (Bug#8762)
15291 * gnutls.c: Use Emacs's memory allocators.
15292 Without this change, the gnutls library would invoke malloc etc.
15293 directly, which causes problems on non-SYNC_INPUT hosts, and which
15294 runs afoul of improving memory_full behavior. (Bug#8761)
15295 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
15296 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
15297 xfree instead of the default malloc, realloc, free.
15298 (Fgnutls_boot): No need to check for memory allocation failure,
15299 since xmalloc does that for us.
15301 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
15302 * category.c (hash_get_category_set):
15303 * ccl.c (ccl_driver):
15304 * charset.c (Fdefine_charset_internal):
15305 * charset.h (struct charset.hash_index):

15307 (composition_gstring_put_cache):
15308 * composite.h (struct composition.hash_index):

15311 (cmpfn_equal, cmpfn_user_defined, hashfn_eq, hashfn_eql)
15312 (hashfn_equal, hashfn_user_defined, make_hash_table)
15313 (maybe_resize_hash_table, hash_lookup, hash_put)
15314 (hash_remove_from_table, hash_clear, sweep_weak_table, SXHASH_COMBINE)
15315 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
15316 (Fsxhash, Fgethash, Fputhash, Fmaphash):
15317 * image.c (make_image, search_image_cache, lookup_image)
15318 (xpm_put_color_table_h):
15319 * lisp.h (struct Lisp_Hash_Table):
15320 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
15321 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
15322 for hashes and hash indexes, instead of 'unsigned' and 'int'.
15323 * alloc.c (allocate_vectorlike):
15324 Check for overflow in vector size calculations.
15325 * ccl.c (ccl_driver):
15326 Check for overflow when converting EMACS_INT to int.
15327 * fns.c, image.c: Remove unnecessary static decls that would otherwise
15328 need to be updated by these changes.
15329 * fns.c (make_hash_table, maybe_resize_hash_table):
15330 Check for integer overflow with large hash tables.
15331 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
15332 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
15333 (SXHASH_REDUCE): New macro.
15334 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
15335 Use it instead of discarding useful hash info with large hash values.
15336 (sxhash_float): New function.
15337 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
15338 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
15339 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
15340 Rewrite to use FIXNUM_BITS, as this simplifies things.
15341 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
15342 Adjust signatures to match updated version of code.
15343 (consing_since_gc): Now EMACS_INT, since a single hash table can
15344 use more than INT_MAX bytes.
15346 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
15348 Make it possible to build with GCC-4.6+ -O2 -flto.
15350 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
15352 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
15354 * minibuf.c (get_minibuffer, read_minibuf_unwind):
15355 Call minibuffer-inactive-mode.
15357 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
15359 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
15360 Update dependencies.
15362 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
15364 * data.c (init_data): Remove code for UTS, this system is not
15367 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
15369 Don't force ./temacs to start in terminal mode.
15371 * frame.c (make_initial_frame): Initialize faces in all cases, not
15372 only when CANNOT_DUMP is defined.
15373 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
15375 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
15377 * dispnew.c (add_window_display_history): Use const for the string
15378 pointer. Remove declaration, not needed.
15380 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
15382 Use 'inline', not 'INLINE'.
15383 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
15384 * alloc.c, fontset.c (INLINE): Remove.
15385 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
15386 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
15387 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
15388 * gmalloc.c (register_heapinfo): Use inline unconditionally.
15389 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
15391 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
15393 Make it possible to run ./temacs.
15395 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
15396 syms_of_callproc does the same thing. Remove test for
15397 "initialized", do it in the caller.
15398 * emacs.c (main): Avoid calling set_initial_environment when dumping.
15400 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
15402 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
15403 (read_minibuf): Use get_minibuffer.
15404 (syms_of_minibuf): Use DEFSYM.
15405 (Qmetadata): New var.
15406 * data.c (Qbuffer): Don't make it static.
15407 (syms_of_data): Use DEFSYM.
15409 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
15411 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
15412 (CCL_CODE_MIN): New macro.
15414 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
15416 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
15418 * eval.c (Qdebug): Now static.
15419 * lisp.h (Qdebug): Remove decl. This reverts a part of the
15420 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
15421 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
15423 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
15425 * image.c: Various fixes to ImageMagick code comments.
15426 (Fimagemagick_types): Doc fix.
15428 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
15430 Minor fixes prompted by GCC 4.6.0 warnings.
15432 * xselect.c (converted_selections, conversion_fail_tag): Now static.
15434 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
15435 (x_clipboard_manager_save_all): Move extern decl to ...
15436 * xterm.h: ... here, so that it can be checked for consistency.
15438 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
15440 * xselect.c (x_clipboard_manager_save_frame)
15441 (x_clipboard_manager_save_all): New functions.
15442 (Fx_clipboard_manager_save): Lisp function deleted.
15444 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
15445 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
15447 * xterm.h: Update prototype.
15449 2011-05-28 William Xu <william.xwl@gmail.com>
15451 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
15452 exiting (Bug#8239).
15454 2011-05-28 Jim Meyering <meyering@redhat.com>
15456 Avoid a sign-extension bug in crypto_hash_function.
15457 * fns.c (to_uchar): Define.
15458 (crypto_hash_function): Use it to convert some newly-signed
15459 variables to unsigned, to avoid sign-extension bugs. For example,
15460 without this change, (md5 "truc") would evaluate to
15461 45723a2aff78ff4fff7fff1114760e62 rather than the expected
15462 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
15463 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
15465 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
15467 Integer overflow fixes.
15469 * dbusbind.c: Serial number integer overflow fixes.
15470 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
15471 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
15472 to hold a serial number that is too large for a fixnum.
15473 (Fdbus_method_return_internal, Fdbus_method_error_internal):
15474 Check for serial numbers out of range. Decode any serial number
15475 that was so large that it became a float. (Bug#8722)
15477 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
15478 (Fdbus_call_method, Fdbus_call_method_asynchronously):
15479 Use XFASTINT rather than XUINT when numbers are nonnegative.
15480 (xd_append_arg, Fdbus_method_return_internal):
15481 (Fdbus_method_error_internal): Likewise. Also, for unsigned
15482 arguments, check that Lisp number is nonnegative, rather than
15483 silently wrapping negative numbers around. (Bug#8722)
15484 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
15487 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
15489 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
15491 ccl: Add integer overflow checks.
15492 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
15493 (IN_INT_RANGE): New macros.
15494 (ccl_driver): Use them to check for integer overflow when
15495 decoding a CCL program. Many of the new checks are whether XINT (x)
15496 fits in int; it doesn't always, on 64-bit hosts. The new version
15497 doesn't catch all possible integer overflows, but it's an
15498 improvement. (Bug#8719)
15500 * alloc.c (make_event_array): Use XINT, not XUINT.
15501 There's no need for unsigned here.
15503 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
15504 This follows up to the 2011-05-06 change that substituted uintptr_t
15505 for EMACS_INT. This case wasn't caught back then.
15507 Rework Fformat to avoid integer overflow issues.
15508 * editfns.c: Include <float.h> unconditionally, as it's everywhere
15509 now (part of C89). Include <verify.h>.
15510 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
15511 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
15512 (Fformat): Avoid the prepass trying to compute sizes; it was only
15513 approximate and thus did not catch overflow reliably. Instead, walk
15514 through the format just once, formatting and computing sizes as we go,
15515 checking for integer overflow at every step, and allocating a larger
15516 buffer as needed. Keep track separately whether the format is
15517 multibyte. Keep only the most-recently calculated precision, rather
15518 than them all. Record whether each argument has been converted to
15519 string. Use EMACS_INT, not int, for byte and char and arg counts.
15520 Support field widths and precisions larger than INT_MAX. Avoid
15521 sprintf's undefined behavior with conversion specifications such as %#d
15522 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
15523 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
15524 formatting out-of-range floating point numbers with int
15525 formats. (Bug#8668)
15527 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
15529 * data.c: Avoid integer truncation in expressions involving floats.
15530 * data.c: Include <intprops.h>.
15531 (arith_driver): When there's an integer overflow in an expression
15532 involving floating point, convert the integers to floating point
15533 so that the resulting value does not suffer from catastrophic
15534 integer truncation. For example, on a 64-bit host (* 4
15535 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
15536 Do not rely on undefined behavior after integer overflow.
15538 merge count_size_as_multibyte, parse_str_to_multibyte
15539 * character.c, character.h (count_size_as_multibyte):
15540 Rename from parse_str_to_multibyte; all uses changed.
15541 Check for integer overflow.
15542 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
15543 since it's now a duplicate of the other. This is more of
15544 a character than a buffer op, so better that it's in character.c.
15545 * fns.c, print.c: Adjust to above changes.
15547 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
15549 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
15551 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
15553 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
15554 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
15555 (x_clipboard_manager_save): Now static.
15556 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
15558 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
15559 (crypto_hash_function): Now static.
15560 Fix pointer signedness problems. Avoid unnecessary initializations.
15562 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
15564 * termhooks.h (Vselection_alist): Make it terminal-local.
15566 * terminal.c (create_terminal): Initialize it.
15568 * xselect.c: Support for clipboard managers.
15569 (Vselection_alist): Move to termhooks.h as terminal-local var.
15570 (LOCAL_SELECTION): New macro.
15571 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
15572 (symbol_to_x_atom): Remove gratuitous arg.
15573 (x_handle_selection_request, lisp_data_to_selection_data)
15574 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
15575 (x_own_selection, x_get_local_selection, x_convert_selection):
15576 New arg, specifying work frame. Use terminal-local Vselection_alist.
15577 (some_frame_on_display): Delete unused function.
15578 (Fx_own_selection_internal, Fx_get_selection_internal)
15579 (Fx_disown_selection_internal, Fx_selection_owner_p)
15580 (Fx_selection_exists_p): New optional frame arg.
15581 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
15582 (x_handle_selection_clear): Don't treat other terminals with the
15583 same keyboard specially. Use the terminal-local Vselection_alist.
15584 (x_clear_frame_selections): Use Frun_hook_with_args.
15586 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
15588 * xterm.h: Add support for those atoms.
15590 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
15592 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
15593 (converted_selections, conversion_fail_tag): New global variables.
15594 (x_selection_request_lisp_error): Free the above.
15595 (x_get_local_selection): Remove unnecessary code.
15596 (x_reply_selection_request): Args changed; handle arbitrary array
15597 of converted selections stored in converted_selections.
15598 Separate the XChangeProperty and SelectionNotify steps.
15599 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
15600 (x_convert_selection): New function.
15601 (x_handle_selection_event): Simplify.
15602 (x_get_foreign_selection): Don't ignore incoming requests while
15603 waiting for an answer; this will fail when we implement
15604 SAVE_TARGETS, and seems unnecessary anyway.
15605 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
15606 (Vx_sent_selection_functions): Doc fix.
15608 2011-05-26 Leo Liu <sdl.web@gmail.com>
15610 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
15612 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15614 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
15616 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
15617 for fringe update if it has periodic bitmap.
15618 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
15619 and fringe_bitmap_periodic_p.
15621 * fringe.c (get_fringe_bitmap_data): New function.
15622 (draw_fringe_bitmap_1, update_window_fringes): Use it.
15623 (update_window_fringes): Record periodicity of fringe bitmap in glyph
15624 row. Mark glyph row for fringe update if periodicity changed.
15626 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
15627 for fringe update unless it has periodic bitmap.
15629 2011-05-25 Kenichi Handa <handa@m17n.org>
15631 * xdisp.c (get_next_display_element): Set correct it->face_id for
15632 a static composition.
15634 2011-05-24 Leo Liu <sdl.web@gmail.com>
15637 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
15639 * fns.c (crypto_hash_function, Fsha1): New function.
15640 (Fmd5): Use crypto_hash_function.
15641 (syms_of_fns): Add Ssha1.
15643 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
15645 * gnutls.c: Remove unused macros.
15646 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
15647 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
15648 Remove macros that are defined and never used.
15649 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
15651 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
15653 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
15654 (Fx_get_selection_internal): Minor cleanup.
15655 (Fx_own_selection_internal): Rename arguments for consistency with
15658 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
15660 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
15662 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
15664 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
15666 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15668 * dispnew.c (scrolling_window): Don't exclude the case that the
15669 last enabled row in the desired matrix touches the bottom boundary.
15671 2011-05-21 Glenn Morris <rgm@gnu.org>
15673 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
15674 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
15675 and add some more files.
15677 2011-05-20 Eli Zaretskii <eliz@gnu.org>
15679 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
15680 report_file_error introduced by the change from 2011-05-07.
15682 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
15684 * systime.h (Time): Define only if emacs is defined.
15685 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
15686 where the include path doesn't have X11/X.h by default. See
15687 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
15689 2011-05-20 Kenichi Handa <handa@m17n.org>
15691 * composite.c (find_automatic_composition): Fix previous change.
15693 2011-05-20 Glenn Morris <rgm@gnu.org>
15695 * lisp.mk: New file, split from Makefile.in.
15696 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
15697 (shortlisp): Remove.
15698 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
15700 2011-05-19 Glenn Morris <rgm@gnu.org>
15702 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
15703 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
15704 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
15705 (lisp): Set the order to that of loadup.el.
15706 (shortlisp): Make it a copy of $lisp.
15707 (SOME_MACHINE_LISP): Remove.
15708 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
15709 Use just $shortlisp, not $SOME_MACHINE_LISP too.
15711 2011-05-18 Kenichi Handa <handa@m17n.org>
15713 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
15714 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
15715 (find_automatic_composition): Mostly rewrite for efficiency.
15717 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
15719 * makefile.w32-in: Update dependencies.
15721 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
15723 * menu.c: Include limits.h (fixes the MS-Windows build broken by
15724 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
15726 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
15728 Fix some integer overflow issues, such as string length overflow.
15730 * insdel.c (count_size_as_multibyte): Check for string overflow.
15732 * character.c (lisp_string_width): Check for string overflow.
15733 Use EMACS_INT, not int, for string indexes and lengths; in
15734 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
15735 the resulting string length overflows an EMACS_INT; instead,
15736 report a string overflow if no precision given. When checking for
15737 precision exhaustion, use a check that cannot possibly have
15738 integer overflow. (Bug#8675)
15739 * character.h (lisp_string_width): Adjust to new signature.
15741 * alloc.c (string_overflow): New function.
15742 (Fmake_string): Use it. This doesn't change behavior, but saves
15743 a few bytes and will simplify future changes.
15744 * character.c (string_escape_byte8): Likewise.
15745 * lisp.h (string_overflow): New decl.
15747 Fixups, following up to the user-interface timestamp change.
15748 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
15749 for UI timestamps, instead of unsigned long.
15750 * msdos.c (mouse_get_pos): Likewise.
15751 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
15752 * w32gui.h (Time): Define by including "systime.h" rather than by
15753 declaring it ourselves. (Bug#8664)
15755 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
15756 * image.c (clear_image_cache): Likewise.
15758 * term.c (term_mouse_position): Don't assume time_t wraparound.
15760 Be more systematic about user-interface timestamps.
15761 Before, the code sometimes used 'Time', sometimes 'unsigned long',
15762 and sometimes 'EMACS_UINT', to represent these timestamps.
15763 This change causes it to use 'Time' uniformly, as that's what X uses.
15764 This makes the code easier to follow, and makes it easier to catch
15765 integer overflow bugs such as Bug#8664.
15766 * frame.c (Fmouse_position, Fmouse_pixel_position):
15767 Use Time, not unsigned long, for user-interface timestamps.
15768 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
15769 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
15770 * keyboard.h (last_event_timestamp): Likewise.
15771 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
15772 * menu.h (xmenu_show): Likewise.
15773 * term.c (term_mouse_position): Likewise.
15774 * termhooks.h (struct input_event.timestamp): Likewise.
15775 (struct terminal.mouse_position_hook): Likewise.
15776 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
15777 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
15778 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
15779 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
15780 what it was before.
15781 * menu.h, termhooks.h: Include "systime.h", for Time.
15783 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
15784 Don't assume that the difference between two unsigned long values
15785 can fit into an integer. At this point, we know button_down_time
15786 <= event->timestamp, so the difference must be nonnegative, so
15787 there's no need to cast the result if double-click-time is
15788 nonnegative, as it should be; check that it's nonnegative, just in
15789 case. This bug is triggered when events are more than 2**31 ms
15790 apart (about 25 days). (Bug#8664)
15792 * xselect.c (last_event_timestamp): Remove duplicate decl.
15793 (x_own_selection): Remove needless cast to unsigned long.
15795 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
15796 that always fit in int. Use a sentinel instead of a counter, to
15797 avoid a temp and to allay GCC's concerns about possible int overflow.
15798 * frame.h (struct frame): Use int for menu_bar_items_used
15799 instead of EMACS_INT, since it always fits in int.
15801 * menu.c (grow_menu_items): Check for int overflow.
15803 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
15805 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
15806 Before, the code was not consistent. These values cannot exceed
15807 2**31 - 1 so there's no need to make them unsigned.
15808 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
15809 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
15810 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
15812 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
15814 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
15815 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
15816 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
15817 presumably because the widths might not match.
15819 * window.c (size_window): Avoid needless test at loop start.
15821 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
15823 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
15825 2011-05-12 Drew Adams <drew.adams@oracle.com>
15827 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
15829 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15831 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
15832 `width' to `bar_area_x' and `bar_area_width', respectively.
15833 (x_scroll_run): Take account of fringe background extension.
15835 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
15836 Rename local vars `left' and `width' to `bar_area_x' and
15837 `bar_area_width', respectively.
15838 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
15839 background extension.
15841 2011-05-10 Jim Meyering <meyering@redhat.com>
15843 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
15845 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
15847 * image.c (Finit_image_library): Return t for built-in image types,
15848 like pbm and xbm. (Bug#8640)
15850 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
15852 * w32menu.c (set_frame_menubar): Fix submenu allocation.
15854 2011-05-07 Eli Zaretskii <eliz@gnu.org>
15856 * w32console.c (Fset_screen_color): Doc fix.
15857 (Fget_screen_color): New function.
15858 (syms_of_ntterm): Defsubr it.
15860 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
15861 unlink the temporary file if Fcall_process didn't create it in the
15863 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
15864 child process will be redirected to a file specified with `:file'.
15865 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
15866 cue to call_process_cleanup not to close that handle.
15868 2011-05-07 Ben Key <bkey76@gmail.com>
15870 * makefile.w32-in: The bootstrap-temacs rule now makes use of
15871 one of two shell specific rules, either bootstrap-temacs-CMD or
15872 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
15873 to the previous implementation of the bootstrap-temacs rule.
15874 The bootstrap-temacs-CMD rule is similar to the previous
15875 implementation of the bootstrap-temacs rule except that it
15876 makes use of the ESC_CFLAGS variable instead of the CFLAGS
15879 These changes, along with some changes to nt/configure.bat,
15880 nt/gmake.defs, and nt/nmake.defs, are required to extend my
15881 earlier fix to add support for --cflags and --ldflags options
15882 that include quotes so that it works whether make uses cmd or
15885 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
15887 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
15888 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
15890 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
15891 a string. Handle both cases.
15892 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
15893 (Fdbus_register_method): Use Qinvalid_function.
15895 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
15897 * makefile.w32-in: Update dependencies.
15898 (LISP_H): Add inttypes.h and stdin.h.
15899 (PROCESS_H): Add unistd.h.
15901 2011-05-06 Eli Zaretskii <eliz@gnu.org>
15903 * lread.c: Include limits.h (fixes the MS-Windows build broken by
15904 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
15906 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
15908 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
15910 * term.c (vfatal): Remove stray call to va_end.
15911 It's not needed and the C Standard doesn't allow it here anyway.
15913 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
15914 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
15916 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
15919 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
15921 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
15923 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
15925 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
15927 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
15929 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
15930 * charset.c (Fdefine_charset_internal): Don't initialize
15931 charset.code_space[15]. The value was garbage, on hosts with
15932 32-bit int (Bug#8600).
15934 * lread.c (read_integer): Be more consistent with string-to-number.
15935 Use string_to_number to do the actual conversion; this avoids
15936 rounding errors and fixes some other screwups. Without this fix,
15937 for example, #x1fffffffffffffff was misread as -2305843009213693952.
15938 (digit_to_number): Move earlier, for benefit of read_integer.
15939 Return -1 if the digit is out of range for the base, -2 if it is
15940 not a digit in any supported base. (Bug#8602)
15942 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
15944 * dispnew.c (scrolling_window): Return 1 if we scrolled,
15945 to match comment at start of function. This also removes a
15946 GCC warning about overflow in a 32+64-bit port.
15948 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
15950 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
15951 Reported by Stefan Monnier in
15952 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
15953 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
15954 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
15956 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
15957 (EMACS_UINTPTR): Likewise, with uintptr_t.
15959 * lisp.h: Prefer 64-bit EMACS_INT if available.
15960 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
15961 on 32-bit hosts that have 64-bit int, so that they can access
15963 However, temporarily disable this change unless the temporary
15964 symbol WIDE_EMACS_INT is defined.
15966 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
15968 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
15969 This removes an assumption that EMACS_INT and long are the same
15970 width as pointers. The assumption is true for Emacs porting targets
15971 now, but we want to make other targets possible.
15972 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
15973 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
15974 In the rest of the code, change types of integers that hold casted
15975 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
15976 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
15977 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
15978 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
15979 No need to cast type when ORing.
15980 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
15981 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
15982 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
15983 assume EMACS_INT is the same width as char *.
15984 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
15985 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
15986 Remove no-longer-needed casts.
15987 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
15988 (xg_tool_bar_help_callback, xg_make_tool_item):
15989 Use EMACS_INTPTR to hold an integer
15990 that will be cast to void *; this can avoid a GCC warning
15991 if EMACS_INT is not the same width as void *.
15992 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
15993 * xdisp.c (display_echo_area_1, resize_mini_window_1):
15994 (current_message_1, set_message_1):
15995 Use a local to convert to proper width without a cast.
15996 * xmenu.c (dialog_selection_callback): Likewise.
15998 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
15999 Also, don't assume VALBITS / RAND_BITS is less than 5,
16000 and don't rely on undefined behavior when shifting a 1 left into
16002 * lisp.h (get_random): Change signature to match.
16004 * lread.c (hash_string): Use size_t, not int, for hash computation.
16005 Normally we prefer signed values; but hashing is special, because
16006 it's better to use unsigned division on hash table sizes so that
16007 the remainder is nonnegative. Also, size_t is the natural width
16008 for hashing into memory. The previous code used 'int', which doesn't
16009 retain enough info to hash well into very large tables.
16010 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
16012 * dbusbind.c: Don't possibly lose pointer info when converting.
16013 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
16014 Use XPNTR rather than XHASH, so that the high-order bits of
16015 the pointer aren't lost when converting through void *.
16017 * eval.c (Fautoload): Don't double-shift a pointer.
16019 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
16021 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
16023 * gnutls.c (DEF_GNUTLS_FN):
16024 * image.c (DEF_IMGLIB_FN): Make function pointers static.
16026 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
16028 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
16031 2011-05-05 Eli Zaretskii <eliz@gnu.org>
16033 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
16034 New version that can reserve upto 2GB of heap space.
16036 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
16038 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).

16102 * process.c: Include lisp.h before w32.h, not after.
16103 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
16104 instead of gnutls_record_check_pending.
16106 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
16108 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>

16156 rather than `XVECTOR (FOO)->size'.
16158 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
16159 inttypes.h, as a gnulib replacement is used if it not available in
16162 2011-04-21 Eli Zaretskii <eliz@gnu.org>
16164 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.

16179 aborting when %lld or %lll format is passed.
16180 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
16181 %llo or %llx format is passed. (Bug#8545)
16183 * window.c (window_scroll_line_based): Use a marker instead of
16184 simple variables to record original value of point. (Bug#7952)
16186 * doprnt.c (doprnt): Fix the case where a multibyte sequence
16187 produced by %s or %c overflows available buffer space. (Bug#8545)
16189 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
16191 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
16192 (SIZE_MAX): Move defn after all includes, as they might #define it.
16194 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
16196 * w32.c (init_environment): Warn about defaulting HOME to C:\.
16198 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
16200 * keyboard.c (Qdelayed_warnings_hook): Define.
16201 (command_loop_1): Run `delayed-warnings-hook'
16202 if Vdelayed_warnings_list is non-nil.
16203 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
16204 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
16206 2011-04-28 Eli Zaretskii <eliz@gnu.org>
16208 * doprnt.c (doprnt): Don't return value smaller than the buffer
16209 size if the message was truncated. (Bug#8545).
16211 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
16213 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
16214 (Fx_window_property): #if-0 the whole functions, not just the bodies.
16216 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
16218 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
16220 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
16222 * makefile.w32-in: Update dependencies.
16224 2011-04-27 Eli Zaretskii <eliz@gnu.org>
16226 Improve `doprnt' and its usage. (Bug#8545)
16227 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
16228 `format_end'. Remove support for %l as a conversion specifier.
16229 Don't use xrealloc. Improve diagnostics when the %l size modifier
16230 is used. Update the commentary.
16232 * eval.c (verror): Simplify calculation of size_t.
16234 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
16237 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
16239 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
16242 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
16244 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
16245 This makes this file independent of the recent pseudovector change.
16247 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
16249 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
16251 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
16252 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
16253 Remove unused local.
16254 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
16256 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
16257 GCC 4.6.0 optimizes based on type-based alias analysis.
16258 For example, if b is of type struct buffer * and v of type struct
16259 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
16260 != &v->size, and therefore "v->size = 1; b->size = 2; return
16261 v->size;" must therefore return 1. This assumption is incorrect
16262 for Emacs, since it type-puns struct Lisp_Vector * with many other
16263 types. To fix this problem, this patch adds a new type struct
16264 vectorlike_header that documents the constraints on layout of vectors
16265 and pseudovectors, and helps optimizing compilers not get fooled
16266 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
16267 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
16268 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
16270 (XSETPVECTYPE): Rewrite in terms of new macro.
16271 (XSETPVECTYPESIZE): New macro, specifying both type and size.
16272 This is a bit clearer, and further avoids the possibility of
16273 undesirable aliasing.
16274 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
16275 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
16276 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
16277 since Lisp_Subr is a special case (no "next" field).
16278 (ASIZE): Now uses header.size rather than size.
16279 All previous uses of XVECTOR (foo)->size replaced to use this macro,
16280 to avoid the hassle of writing XVECTOR (foo)->header.size.
16281 (struct vectorlike_header): New type.
16282 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
16283 object, to help avoid aliasing.
16284 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
16285 (SUBRP): Likewise, since Lisp_Subr is a special case.
16286 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
16287 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
16288 (struct Lisp_Hash_Table): Combine first two members into a single
16289 struct vectorlike_header member. All uses of "size" and "next" members
16290 changed to be "header.size" and "header.next".
16291 * buffer.h (struct buffer): Likewise.
16292 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
16293 * frame.h (struct frame): Likewise.
16294 * process.h (struct Lisp_Process): Likewise.
16295 * termhooks.h (struct terminal): Likewise.
16296 * window.c (struct save_window_data, struct saved_window): Likewise.
16297 * window.h (struct window): Likewise.
16298 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
16299 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
16300 * buffer.c (init_buffer_once): Likewise.
16301 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
16303 * process.c (Fformat_network_address): Use local var for size,
16306 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
16308 Make the Lisp reader and string-to-float more consistent (Bug#8525)
16309 * data.c (atof): Remove decl; no longer used or needed.
16310 (digit_to_number): Move to lread.c.
16311 (Fstring_to_number): Use new string_to_number function, to be
16312 consistent with how the Lisp reader treats infinities and NaNs.
16313 Do not assume that floating-point numbers represent EMACS_INT
16314 without losing information; this is not true on most 64-bit hosts.
16315 Avoid double-rounding errors, by insisting on integers when
16316 parsing non-base-10 numbers, as the documentation specifies.
16317 * lisp.h (string_to_number): New decl, replacing ...
16318 (isfloat_string): Remove.
16319 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
16320 (read1): Do not accept +. and -. as integers; this
16321 appears to have been a coding error. Similarly, do not accept
16322 strings like +-1e0 as floating point numbers. Do not report
16323 overflow for integer overflows unless the base is not 10 which
16324 means we have no simple and reliable way to continue.
16325 Break out the floating-point parsing into a new
16326 function string_to_number, so that Fstring_to_number parses
16327 floating point numbers consistently with the Lisp reader.
16328 (digit_to_number): Move here from data.c. Make it static inline.
16329 (E_CHAR, EXP_INT): Remove, replacing with ...
16330 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
16331 (string_to_number): New function, replacing isfloat_string.
16332 This function checks for valid syntax and produces the resulting
16333 Lisp float number too. Rework it so that string-to-number
16334 no longer mishandles examples like "1.0e+". Use strtoumax,
16335 so that overflow for non-base-10 numbers is reported only when
16336 there's no portable and simple way to convert to floating point.
16338 * textprop.c (set_text_properties_1): Rewrite for clarity,
16339 and to avoid GCC warning about integer overflow.
16341 * intervals.h (struct interval): Use EMACS_INT for members
16342 where EMACS_UINT might cause problems. See
16343 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
16344 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
16345 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
16347 (offset_intervals): Tell GCC not to worry about length overflow
16348 when negating a negative length.
16350 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
16351 (overrun_check_free): Likewise.
16353 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
16354 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
16357 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
16358 (gnutls_make_error): Rename local to avoid shadowing.
16359 (gnutls_emacs_global_deinit): ifdef out; not used.
16360 (Fgnutls_boot): Use const for pointer to readonly storage.
16361 Comment out unused local. Fix pointer signedness problems.
16363 * lread.c (openp): Don't stuff size_t into an 'int'.
16364 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
16365 about possible signed overflow.
16367 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
16368 (GDK_KEY_g): Don't define if already defined.
16369 (xg_prepare_tooltip): Avoid pointer signedness problem.
16370 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
16372 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
16373 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
16375 * xfns.c (Fx_window_property): Simplify a bit,
16376 to make a bit faster and to avoid GCC 4.6.0 warning.
16377 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
16379 * fns.c (internal_equal): Don't assume size_t fits in int.
16381 * alloc.c (compact_small_strings): Tighten assertion a little.
16383 Replace pEd with more-general pI, and fix some printf arg casts.
16384 * lisp.h (pI): New macro, generalizing old pEd macro to other
16385 conversion specifiers. For example, use "...%"pI"d..." rather
16386 than "...%"pEd"...".
16387 (pEd): Remove. All uses replaced with similar uses of pI.
16388 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
16389 * alloc.c (check_pure_size): Don't overflow by converting size to int.
16390 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
16391 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
16392 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
16393 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
16394 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
16396 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
16397 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
16398 * print.c (safe_debug_print, print_object): Likewise.
16399 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
16401 Use pI instead of if-then-else-abort. Use %p to avoid casts,
16402 avoiding the 0 flag, which is not portable.
16403 * process.c (Fmake_network_process): Use pI to avoid cast.
16404 * region-cache.c (pp_cache): Likewise.
16405 * xdisp.c (decode_mode_spec): Likewise.
16406 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
16407 behavior on 64-bit hosts with printf arg.
16408 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
16409 (x_stop_queuing_selection_requests): Likewise.
16410 (x_get_window_property): Don't truncate byte count to an 'int'
16413 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
16414 here, since it parses constructs like leading '-' and spaces,
16415 which are not wanted; and it overflows with large numbers.
16416 Instead, simply match F[0-9]+, which is what is wanted anyway.
16418 * alloc.c: Remove unportable assumptions about struct layout.
16419 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
16420 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
16421 (allocate_vectorlike, make_pure_vector): Use the new macros,
16422 plus offsetof, to remove unportable assumptions about struct layout.
16423 These assumptions hold on all porting targets that I know of, but
16424 they are not guaranteed, they're easy to remove, and removing them
16425 makes further changes easier.
16427 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
16428 This doesn't fix a bug but makes the code clearer.
16429 (string_overrun_cookie): Now const. Use initializers that
16430 don't formally overflow signed char, to avoid warnings.
16431 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
16432 can cause Emacs to crash when string overrun checking is enabled.
16433 (allocate_buffer): Don't assume sizeof (struct buffer) is a
16434 multiple of sizeof (EMACS_INT); it need not be, if
16435 alignof(EMACS_INT) < sizeof (EMACS_INT).
16436 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
16438 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
16440 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
16442 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
16444 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
16445 supposed to be handshaking. (Bug#8556)
16446 Reported by Paul Eggert <eggert@cs.ucla.edu>.
16448 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
16450 * lisp.h (Qdebug): List symbol.
16451 * eval.c (Qdebug): Restore global linkage.
16452 * keyboard.c (debug-on-event): New variable.
16453 (handle_user_signal): Break into debugger when debug-on-event
16454 matches the current signal symbol.

17209 to see whether these functions can be called from other modules.
17210 DEFUN now defines a static function. To make the function external
17211 so that it can be used in other C modules, use the new macro DEFUE.

17289 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
17290 since callers should never pass a negative size.
17291 Change the signature to match that of plain 'read' and 'write'; see
17292 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
17293 * lisp.h: Update prototypes of emacs_write and emacs_read.
17295 2011-04-11 Eli Zaretskii <eliz@gnu.org>
17297 * xdisp.c (redisplay_window): Don't try to determine the character
17298 position of the scroll margin if the window start point w->startp
17299 is outside the buffer's accessible region. (Bug#8468)
17301 2011-04-10 Eli Zaretskii <eliz@gnu.org>
17303 Fix write-region and its subroutines for buffers > 2GB.
17304 * fileio.c (a_write, e_write): Modify declaration of arguments and
17305 local variables to support buffers larger than 2GB.
17306 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
17308 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
17309 argument, local variables, and return value.
17311 * lisp.h: Update prototypes of emacs_write and emacs_read.
17313 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
17315 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
17317 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.

17321 * xdisp.c (vmessage): Use a better test for character truncation.
17323 * charset.c (load_charset_map): <, not <=, for optimization,

17333 * callint.c (Fcall_interactively): <, not <=, for optimization.
17334 (Fcall_interactively): Count the number of arguments produced,
17335 not the number of arguments given. This is simpler and lets GCC
17336 4.6.0 generate slightly better code.
17338 * ftfont.c: Distingish more carefully between FcChar8 and char.
17339 The previous code passed unsigned char * to a functions like
17340 strlen and xstrcasecmp that expect char *, which does not
17341 conform to the C standard.
17342 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
17343 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
17344 char * when the C standard requires it.
17346 * keyboard.c (read_char): Remove unused var.
17348 * eval.c: Port to Windows vsnprintf (Bug#8435).
17349 Include <limits.h>.

17351 (verror): Do not give up if vsnprintf returns a negative count.
17352 Instead, grow the buffer. This ports to Windows vsnprintf, which
17353 does not conform to C99. Problem reported by Eli Zaretskii.
17354 Also, simplify the allocation scheme, by avoiding the need for
17355 calling realloc, and removing the ALLOCATED variable.
17357 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
17359 Remove invocations of doprnt, as Emacs now uses vsnprintf.
17360 But keep the doprint source code for now, as we might revamp it
17361 and use it again (Bug#8435).
17362 * lisp.h (doprnt): Remove.
17363 * Makefile.in (base_obj): Remove doprnt.o.
17364 * deps.mk (doprnt.o): Remove.
17366 error: Print 32- and 64-bit integers portably (Bug#8435).
17367 Without this change, on typical 64-bit hosts error ("...%d...", N)
17368 was used to print both 32- and 64-bit integers N, which relied on
17369 undefined behavior.
17370 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
17371 * lisp.h (error, verror): Mark as printf-like functions.
17372 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
17373 Report overflow in size calculations when allocating printf buffer.
17374 Do not truncate output string at its first null byte.
17375 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
17376 Truncate the output at a character boundary, since vsnprintf does not
17378 * charset.c (check_iso_charset_parameter): Convert internal
17379 character to string before calling 'error', since %c now has the
17381 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
17382 overflow when computing char to be passed to 'error'. Do not
17383 pass Lisp_Object to 'error'; pass the integer instead.
17384 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
17385 formatted with plain %d.
17387 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
17389 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
17391 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
17393 * xterm.c (x_catch_errors): Remove duplicate declaration.
17395 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
17397 * xdisp.c, lisp.h (message_nolog): Remove; unused.
17399 2011-04-10 Jim Meyering <meyering@redhat.com>
17401 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
17402 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
17403 return ssize_t not "int", and use size_t as the buffer length.
17404 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
17405 * gnutls.h: Update declarations.
17406 * process.c (read_process_output): Use ssize_t, to match.
17407 (send_process): Likewise.

17411 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
17413 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
17415 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
17416 Use unsigned char, to match FcChar8 type definition.
17418 * xterm.c (handle_one_xevent):
17419 * xmenu.c (create_and_show_popup_menu):
17420 * xselect.c (x_decline_selection_request)
17421 (x_reply_selection_request): Avoid type-punned deref of X events.
17423 2011-04-09 Eli Zaretskii <eliz@gnu.org>
17425 Fix some uses of `int' instead of EMACS_INT.

17433 EMACS_INT. All callers changed.
17434 (pint2hrstr): Last argument is now EMACS_INT.

17449 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
17450 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
17452 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
17453 (encode_invocation_designation): Last argument P_NCHARS is now
17455 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
17456 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
17458 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.

17479 instead of using internal_with_output_to_temp_buffer.
17480 (Qhelp_form_show): New var.
17481 (syms_of_keyboard): Use DEFSYM macro.
17483 * print.c (internal_with_output_to_temp_buffer): Function deleted.

17517 to system-supplied API.
17519 * eval.c (Fsignal): Remove excess argument to 'fatal'.
17521 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
17522 This avoids several warnings with gcc -Wstrict-overflow.
17523 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
17524 directly, rather than having caller test rule sign. This avoids
17525 some unnecessary tests.
17526 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
17527 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
17528 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
17530 * xfont.c (xfont_text_extents): Remove var that was set but not used.
17531 (xfont_open): Avoid unnecessary tests.
17533 * composite.c (composition_gstring_put_cache): Use unsigned integer.
17535 * composite.h, composite.c (composition_gstring_put_cache):
17536 Use EMACS_INT, not int, for length.

17539 breaking out part of COMPOSITION_DECODE_RULE.
17540 (COMPOSITION_DECODE_RULE): Use it.
17541 * composite.c (get_composition_id): Remove unused local vars,
17542 by using the new macro.
17544 * textprop.c (set_text_properties_1): Change while to do-while,
17545 since the condition is always true at first.
17547 * intervals.c (graft_intervals_into_buffer): Mark var as used.
17548 (interval_deletion_adjustment): Return unsigned value.
17551 * process.c (list_processes_1, create_pty, read_process_output):
17552 (exec_sentinel): Remove vars that were set but not used.
17553 (create_pty): Remove unnecessary "volatile"s.

17565 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
17567 * print.c (print_error_message): Avoid int overflow.
17569 * font.c (font_list_entities): Redo for clarity,
17570 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
17572 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
17573 (font_score): Avoid potential overflow in diff calculation.
17575 * fns.c (substring_both): Remove var that is set but not used.
17576 (sxhash): Redo loop for clarity and to avoid wraparound warning.
17578 * eval.c (funcall_lambda): Rename local to avoid shadowing.
17580 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
17581 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
17582 can always succeed if overflow has undefined behavior.
17584 * search.c (boyer_moore, wordify): Remove vars set but not used.
17585 (wordify): Omit three unnecessary tests.
17587 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
17588 All callers changed. This avoids the need for an unused var.
17590 * casefiddle.c (casify_region): Remove var that is set but not used.
17592 * dired.c (file_name_completion): Remove var that is set but not used.
17594 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
17596 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
17597 (Finsert_file_contents): Remove unnecessary code checking fd.
17599 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
17600 Check for integer overflow on size calculations.
17602 * buffer.c (Fprevious_overlay_change): Remove var that is set
17605 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
17606 Remove vars that are set but not used.
17607 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
17608 (timer_check_2): Mark vars as initialized.
17610 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
17612 * image.c (lookup_image): Remove var that is set but not used.
17613 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
17615 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
17616 that are set but not used.
17618 * xfns.c (make_invisible_cursor): Don't return garbage
17619 if XCreateBitmapFromData fails (Bug#8410).
17621 * xselect.c (x_get_local_selection, x_handle_property_notify):
17622 Remove vars that are set but not used.
17624 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
17625 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
17627 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
17628 Remove var that is set but not used.
17629 (scroll_bar_windows_size): Now size_t, not int.
17630 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
17631 Check for overflow.
17633 * xfaces.c (realize_named_face): Remove vars that are set but not used.
17634 (map_tty_color) [!defined MSDOS]: Likewise.
17636 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
17638 * coding.c: Remove vars that are set but not used.
17639 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
17640 All callers changed.

17642 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
17643 (decode_coding_charset): Remove vars that are set but not used.
17645 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
17646 that is set but not used.
17648 * print.c (print_object): Remove var that is set but not used.
17650 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
17651 The gnulib version avoids calling malloc in the usual case,
17652 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
17653 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
17654 * filelock.c (current_lock_owner): Likewise.
17655 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
17656 * sysdep.c: Include allocator.h, careadlinkat.h.
17657 (emacs_no_realloc_allocator): New static constant.
17658 (emacs_readlink): New function.
17659 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
17660 ../lib/careadlinkat.h.
17662 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
17664 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
17665 first non-nil return value).
17667 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
17669 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6

17679 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
17680 and thereabouts. All callers changed.
17681 (get_per_char_metric): Remove parameter `f', unused since
17682 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
17684 2011-04-02 Jim Meyering <meyering@redhat.com>
17686 do not dereference NULL upon failed strdup
17687 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
17688 (ns_get_family): Likewise.
17690 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
17692 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
17694 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
17696 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or

17714 (syms_of_lread): Declare `lexical-binding'.
17716 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
17718 * keyboard.c (eval_dyn): New fun.
17719 (menu_item_eval_property): Use it.
17721 * image.c (parse_image_spec): Use Ffunctionp.
17723 * fns.c (concat, mapcar1): Accept byte-code-functions.
17725 * eval.c (Fsetq): Handle lexical vars.
17726 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
17727 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
17728 (FletX, Flet): Obey lexical binding.
17729 (Fcommandp): Handle closures.
17730 (Feval): New `lexical' arg.
17731 (eval_sub): New function extracted from Feval. Use it almost
17732 everywhere where Feval was used. Look up vars in lexical env.
17734 (Ffunctionp): Move from subr.el.
17735 (Ffuncall): Handle closures.
17736 (apply_lambda): Remove `eval_flags'.
17737 (funcall_lambda): Handle closures and new byte-code-functions.
17738 (Fspecial_variable_p): New function.
17739 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
17740 but without exporting it to Lisp.
17742 * doc.c (Fdocumentation, store_function_docstring):
17743 * data.c (Finteractive_form): Handle closures.
17745 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
17748 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
17750 (exec_byte_code): New function extracted from Fbyte_code to handle new
17751 calling convention for byte-code-functions. Add new byte-codes.
17753 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
17755 * alloc.c (Fmake_symbol): Init new `declared_special' field.
17757 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
17759 * xdisp.c (redisplay_internal): Fix prototype.
17761 2011-03-31 Eli Zaretskii <eliz@gnu.org>
17763 * xdisp.c (SCROLL_LIMIT): New macro.
17764 (try_scrolling): Use it when setting scroll_limit.
17765 Limit scrolling to 100 screen lines.
17766 (redisplay_window): Even when falling back on "recentering",
17767 position point in the window according to scroll-conservatively,
17768 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
17770 (try_scrolling): When point is above the window, allow searching
17771 as far as scroll_max, or one screenful, to compute vertical
17772 distance from PT to the scroll margin position. This prevents
17773 try_scrolling from unnecessarily failing when
17774 scroll-conservatively is set to a value slightly larger than the
17775 window height. Clean up the case of PT below the margin at bottom
17776 of window: scroll_max can no longer be INT_MAX. When aggressive
17777 scrolling is in use, don't let point enter the opposite scroll
17778 margin as result of the scroll.
17779 (syms_of_xdisp) <scroll-conservatively>: Document the
17780 threshold of 100 lines for never-recentering scrolling.

17787 (message_log_check_duplicate): Remove parameters `prev_bol' and
17788 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
17789 (redisplay_internal): Remove parameter `preserve_echo_area',
17790 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
17792 * indent.c (Fvertical_motion):
17793 * window.c (window_scroll_pixel_based, Frecenter):
17794 Don't pass `need_y_p' to `move_it_by_lines'.
17796 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
17798 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
17799 steal a few bits to be more compact.
17800 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
17801 Remove unneeded casts.
17803 * bytecode.c (Fbyte_code): CAR and CDR can GC.
17805 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
17807 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
17808 binding" message (bug#7967).
17810 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
17812 Fix more problems found by GCC 4.6.0's static checks.
17814 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
17815 Remove unused local var.
17817 * editfns.c (Fmessage_box): Remove unused local var.
17819 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
17820 (note_mode_line_or_margin_highlight, note_mouse_highlight):
17821 Omit unused local vars.
17822 * window.c (shrink_windows): Omit unused local var.
17823 * menu.c (digest_single_submenu): Omit unused local var.
17824 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
17825 Omit unused local var.
17827 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
17828 Don't assume string length fits in int.
17829 (keyremap_step, read_key_sequence): Use size_t for sizes.
17830 (read_key_sequence): Don't check last_real_key_start redundantly.
17832 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
17833 instead of alloca (Bug#8344).
17835 * eval.c (Fbacktrace): Don't assume nargs fits in int.
17836 (Fbacktrace_frame): Don't assume nframes fits in int.
17838 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
17840 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
17843 * term.c (produce_glyphless_glyph): Remove unnecessary test.
17845 * cm.c (calccost): Turn while-do into do-while, for clarity.
17847 * keyboard.c (syms_of_keyboard): Use the same style as later
17848 in this function when indexing through an array. This also
17849 works around GCC bug 48267.
17851 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
17853 * xselect.c (x_check_property_data): Return correct size (Bug#8335).

17856 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
17858 * keyboard.c, keyboard.h (num_input_events): Now size_t.
17859 This avoids undefined behavior on integer overflow, and is a bit
17860 more convenient anyway since it is compared to a size_t variable.
17862 Variadic C functions now count arguments with size_t, not int.
17863 This avoids an unnecessary limitation on 64-bit machines, which
17864 caused (substring ...) to crash on large vectors (Bug#8344).
17865 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
17866 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
17867 All variadic functions and their callers changed accordingly.
17868 (struct gcpro.nvars): Now size_t, not int. All uses changed.

17870 * editfns.c (general_insert_function): Likewise.
17871 * eval.c (struct backtrace.nargs, interactive_p)
17872 (internal_condition_case_n, run_hook_with_args, apply_lambda)
17873 (funcall_lambda, mark_backtrace): Likewise.
17874 * fns.c (concat): Likewise.
17875 * frame.c (x_set_frame_parameters): Likewise.
17876 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
17877 0 if not found, not -1. All callers changed.
17879 * alloc.c (garbage_collect): Don't assume stack size fits in int.
17880 (stack_copy_size): Now size_t, not int.
17881 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
17883 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
17885 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
17886 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
17887 All callers changed.
17889 * lisp.h (multibyte_char_to_unibyte):
17890 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
17891 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
17892 * character.h (CHAR_TO_BYTE8):
17893 * cmds.c (internal_self_insert):
17894 * editfns.c (general_insert_function):
17895 * keymap.c (push_key_description):
17896 * search.c (Freplace_match):
17897 * xdisp.c (message_dolog, set_message_1): All callers changed.
17899 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
17901 * keyboard.c (safe_run_hook_funcall): New function.
17902 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
17903 don't set the hook to nil, but remove the offending function instead.
17904 (Qcommand_hook_internal): Remove, unused.
17905 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
17906 Vcommand_hook_internal.
17908 * eval.c (enum run_hooks_condition): Remove.
17909 (funcall_nil, funcall_not): New functions.
17910 (run_hook_with_args): Call each function through a `funcall' argument.
17911 Remove `cond' argument, now redundant.
17912 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
17913 (Frun_hook_with_args_until_failure): Adjust accordingly.
17914 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
17916 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
17918 * dispextern.h (string_buffer_position): Remove declaration.
17920 * print.c (strout): Remove parameter `multibyte', unused since
17921 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
17923 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
17924 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
17925 All callers changed.
17927 * w32.c (_wsa_errlist): Use braces for struct initializers.
17929 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
17930 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
17931 All callers changed.
17932 (string_buffer_position): Likewise. Also, make static (it's never
17933 used outside xdisp.c).
17934 (cursor_row_p): Remove parameter `w', unused since
17935 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.

17937 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
17938 All callers changed.
17940 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
17942 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.
17944 2011-03-27 Anders Lindgren <andlind@gmail.com>

17947 (ns_constrain_all_frames, ns_menu_bar_should_be_hidden)
17948 (ns_update_auto_hide_menu_bar): New functions.
17949 (ns_update_begin): Call ns_update_auto_hide_menu_bar.

17953 (syms_of_nsterm): DEFVAR ns-auto-hide-menu-bar, init to Qnil.
17955 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
17957 * nsmenu.m (runDialogAt): Remove argument to timer_check.
17959 2011-03-27 Glenn Morris <rgm@gnu.org>
17961 * syssignal.h: Replace RETSIGTYPE with void.
17962 * atimer.c, data.c, dispnew.c, emacs.c, floatfns.c, keyboard.c:
17963 * keyboard.h, lisp.h, process.c, sysdep.c, xterm.c:
17964 Replace SIGTYPE with void everywhere.

17968 2011-03-26 Eli Zaretskii <eliz@gnu.org>
17970 * xdisp.c (redisplay_window): Don't check buffer's clip_changed
17971 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
17973 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
17975 * w32.c (read_unc_volume): Use parameter `henum', instead of
17976 global variable `wget_enum_handle'.
17978 * keymap.c (describe_vector): Remove parameters `indices' and
17979 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.

17991 * xmenu.c (show_help_event, menu_help_callback):
17992 Adjust calls to `show_help_echo'.
17994 * gtkutil.c (xg_maybe_add_timer):
17995 * keyboard.c (readable_events):
17996 * process.c (wait_reading_process_output):
17997 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
17999 * insdel.c (adjust_markers_gap_motion):
18000 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.

18074 2011-03-23 Julien Danjou <julien@danjou.info>
18076 * term.c (Fsuspend_tty, Fresume_tty):
18077 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
18078 * window.c (temp_output_buffer_show):
18079 * insdel.c (signal_before_change):

18083 * editfns.c (save_excursion_restore):
18084 * cmds.c (internal_self_insert):
18085 * callint.c (Fcall_interactively):
18086 * buffer.c (Fkill_all_local_variables):
18087 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
18089 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
18090 unconditionally since it does the check itself.
18092 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
18094 Fix more problems found by GCC 4.5.2's static checks.
18096 * coding.c (encode_coding_raw_text): Avoid unnecessary test
18097 the first time through the loop, since we know p0 < p1 then.
18098 This also avoids a gcc -Wstrict-overflow warning.
18100 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
18101 leading to a memory leak, possible in functions like
18102 load_charset_map_from_file that can allocate an unbounded number
18103 of objects (Bug#8318).
18105 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
18106 that could (at least in theory) be that large.
18108 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
18109 This is less likely to overflow, and avoids undefined behavior if
18110 overflow does occur. All callers changed. Use strtoul to scan
18111 for the unsigned long integer.
18112 (pint2hrstr): Simplify and tune code slightly.
18113 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

18121 This also avoids a warning with gcc -Wstrict-overflow.
18123 * fileio.c (Fcopy_file): Report error if fchown or fchmod
18126 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
18128 * process.c (Fmake_network_process): Use socklen_t, not int,
18129 where POSIX says socklen_t is required in portable programs.
18130 This fixes a porting bug on hosts like 64-bit HP-UX, where
18131 socklen_t is wider than int (Bug#8277).
18132 (Fmake_network_process, server_accept_connection):
18133 (wait_reading_process_output, read_process_output):
18136 * process.c: Rename or move locals to avoid shadowing.
18137 (list_processes_1, Fmake_network_process):
18138 (read_process_output_error_handler, exec_sentinel_error_handler):
18139 Rename or move locals.
18140 (Fmake_network_process): Define label "retry_connect" only if needed.
18141 (Fnetwork_interface_info): Fix pointer signedness.

18143 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
18144 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
18146 Make tparam.h and terminfo.c consistent.
18147 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
18148 Include tparam.h instead, since it declares them.
18149 * cm.h (PC): Remove extern decl; tparam.h now does this.
18150 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
18151 * terminfo.c: Include tparam.h, to check interfaces.
18152 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
18153 (tparam): Adjust signature to match interface in tparam.h;
18154 this removes some undefined behavior. Check that outstring and len
18155 are zero, which they always are with Emacs.
18156 * tparam.h (PC, BC, UP): New extern decls.
18158 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
18159 (xftfont_open): Rename locals to avoid shadowing.
18161 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
18162 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
18163 (OTF_TAG_SYM): Omit macro if not needed.
18164 (ftfont_list): Remove unused local.
18165 (get_adstyle_property, ftfont_pattern_entity):
18166 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
18167 Rename locals to avoid shadowing.
18169 * xfont.c (xfont_list_family): Mark var as initialized.
18171 * xml.c (make_dom): Now static.
18173 * composite.c (composition_compute_stop_pos): Rename local to
18175 (composition_reseat_it): Remove unused locals.
18176 (find_automatic_composition, composition_adjust_point): Likewise.
18177 (composition_update_it): Mark var as initialized.
18178 (find_automatic_composition): Mark vars as initialized,
18179 with a FIXME (Bug#8290).
18181 character.h: Rename locals to avoid shadowing.
18182 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
18183 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
18184 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
18185 (BUF_DEC_POS): Be more systematic about renaming local temporaries
18186 to avoid shadowing.
18188 * textprop.c (property_change_between_p): Remove; unused.
18190 * intervals.c (interval_start_pos): Now static.
18192 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".
18194 * atimer.c (start_atimer, append_atimer_lists, set_alarm):
18195 Rename locals to avoid shadowing.
18197 * sound.c (wav_play, au_play, Fplay_sound_internal):
18198 Fix pointer signedness.
18199 (alsa_choose_format): Remove unused local var.
18200 (wav_play): Initialize a variable to 0, to prevent undefined
18201 behavior (Bug#8278).
18203 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
18205 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
18207 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
18208 clobbering (Bug#8298).
18209 * sysdep.c (sys_subshell): Likewise.
18210 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
18212 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
18213 This should get cleaned up, so that child_setup has the
18214 same signature on all platforms.
18216 * callproc.c (call_process_cleanup): Now static.
18217 (relocate_fd): Rename locals to avoid shadowing.
18219 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
18221 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
18222 not to be necessary, and produces flickering.
18224 2011-03-20 Glenn Morris <rgm@gnu.org>
18226 * config.in: Remove file.
18228 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
18230 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
18231 are now in src/globals.h.
18232 (syms_of_minibuf): Remove spurious & from previous change.

18242 * xfaces.c (Fx_load_color_file):
18243 Read color file from absolute filename (bug#8250).
18245 2011-03-19 Juanma Barranquero <lekktu@gmail.com>

18309 instead of using an uninitialized var.
18310 (font_sort_entities): Mark var as initialized.
18312 * character.h (FETCH_CHAR_ADVANCE): Rename locals to avoid shadowing.

18330 * lisp.h: ... to here, so that it can be checked.
18332 * eval.c (call_debugger, do_debug_on_call, grow_specpdl): Now static.
18333 (Fdefvar): Rewrite so as not to use empty "else".

18338 * callint.c (quotify_arg, quotify_args): Now static.
18339 (Fcall_interactively): Rename locals to avoid shadowing.

18347 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
18348 some of which prompt warnings from gcc -Wbad-function-cast.
18349 (Fformat_time_string, Fencode_time, Finsert_char):
18350 (Ftranslate_region_internal, Fformat):

18378 (Fmemory_limit): Cast sbrk's returned value to char *.
18380 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
18381 avoids undefined behavior in theory.
18383 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
18385 Use functions, not macros, for up- and down-casing (Bug#8254).
18386 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
18387 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
18388 to use the following functions instead of these macros.
18389 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
18390 EMACS_INT, since callers assume the returned value fits in int.
18391 (upcase1): Likewise, for UPCASE_TABLE.
18392 (uppercasep, lowercasep, upcase): New static inline functions.
18393 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

18399 (regex_compile, re_search_2, re_match_2_internal):
18400 Remove unused local vars.

18402 which gcc can warn about.
18403 (regex_compile, re_match_2_internal): Mark locals as initialized.
18404 (RETALLOC_IF): Define only if needed.
18405 (WORDCHAR_P): Likewise. This one is never needed, but is used
18406 only in a comment talking about a compiler bug, so put inside
18407 the #if 0 of that comment.
18408 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
18409 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
18412 * search.c (boyer_moore): Rename locals to avoid shadowing.

18427 Rename locals to avoid shadowing.
18428 (Fvertical_motion): Mark locals as initialized.
18430 * casefiddle.c (casify_object, casify_region): Now static.
18431 (casify_region): Mark local as initialized.

18435 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
18436 New macros, so that the caller can use some names other than
18437 gcpro1, gcpro2, etc.
18438 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
18440 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
18441 argument, for consistency with GCPRO2_VAR, etc: it is now the
18442 prefix of the variable, not the variable itself. All uses
18444 * dired.c (directory_files_internal, file_name_completion):
18445 Rename locals to avoid shadowing.
18447 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
18448 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
18449 dired.c's scmp function, had undefined behavior.
18450 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
18451 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
18452 * buffer.h: ... to here, because these macros use current_buffer,
18453 and the new implementation with inline functions needs to have
18454 current_buffer in scope now, rather than later when the macros
18456 (downcase, upcase1): New static inline functions.
18457 (DOWNCASE, UPCASE1): Reimplement using these functions.
18458 This avoids undefined behavior in expressions like
18459 DOWNCASE (x) == DOWNCASE (y), which previously suffered
18460 from race conditions in accessing the global variables
18461 case_temp1 and case_temp2.
18462 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
18463 * lisp.h (case_temp1, case_temp2): Remove their decls.
18464 * character.h (ASCII_CHAR_P): Move from here ...
18465 * lisp.h: ... to here, so that the inline functions mentioned
18466 above can use them.
18468 * dired.c (directory_files_internal_unwind): Now static.
18470 * fileio.c (file_name_as_directory, directory_file_name):
18471 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
18473 (file_name_as_directory): Use const pointers when appropriate.
18474 (Fexpand_file_name): Likewise. In particular, newdir might
18475 point at constant storage, so make it a const pointer.
18476 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
18477 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
18479 (Fset_file_times, Finsert_file_contents, auto_save_error):
18480 Rename locals to avoid shadowing.

18484 to avoid shadowing.
18486 * marker.c (bytepos_to_charpos): Remove; unused.
18488 * lisp.h (verify_bytepos, count_markers): New decls,
18489 so that gcc does not warn that these functions aren't declared.
18491 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
18492 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
18493 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
18494 (copy_text): Remove unused local var.
18496 * filelock.c (within_one_second): Now static.
18497 (lock_file_1): Rename local to avoid shadowing.
18499 * buffer.c (fix_overlays_before): Mark locals as initialized.
18500 (fix_start_end_in_overlays): Likewise. This function should be
18501 simplified by using pointers-to-pointers, but that's a different
18503 (switch_to_buffer_1): Now static.
18504 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
18505 (report_overlay_modification): Rename locals to avoid shadowing.
18507 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
18508 Fix pointer signedness issue.
18509 (sys_subshell): Mark local as volatile if checking for lint,
18510 to suppress a gcc -Wclobbered warning that does not seem to be right.
18511 (MAXPATHLEN): Define only if needed.
18513 * process.c (serial_open, serial_configure): Move decls from here ...
18514 * systty.h: ... to here, so that they can be checked.
18516 * fns.c (get_random, seed_random): Move extern decls from here ...
18517 * lisp.h: ... to here, so that they can be checked.
18519 * sysdep.c (reset_io): Now static.
18520 (wait_for_termination_signal): Remove; unused.
18522 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
18523 (copy_keymap_item, append_key, push_text_char_description):
18525 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
18526 (DENSE_TABLE_SIZE): Remove; unused.
18527 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
18528 (describe_map_tree):
18529 Rename locals to avoid shadowing.
18531 * keyboard.c: Declare functions static if they are not used elsewhere.
18532 (echo_char, echo_dash, cmd_error, top_level_2):
18533 (poll_for_input, handle_async_input): Now static.
18534 (read_char, kbd_buffer_get_event, make_lispy_position):
18535 (make_lispy_event, make_lispy_movement, apply_modifiers):
18536 (decode_keyboard_code, tty_read_avail_input, menu_bar_items):
18537 (parse_tool_bar_item, read_key_sequence, Fread_key_sequence):
18538 (Fread_key_sequence_vector): Rename locals to avoid shadowing.
18539 (read_key_sequence, read_char): Mark locals as initialized.

18549 (DEFINE_DUMMY_FUNCTION): New macro.
18550 (__do_global_ctors, __do_global_ctors_aux, __do_global_dtors, __main):

18616 (BUF_PT_BYTE): Rewrite to handle indirect buffers (Bug#8219).
18617 These macros can no longer be used for assignment.
18619 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):

18675 2011-03-12 Paul Eggert <eggert@cs.ucla.edu>
18677 Improve quality of tests for time stamp overflow.
18678 For example, without this patch (encode-time 0 0 0 1 1
18679 1152921504606846976) returns the obviously-bogus value (-948597
18680 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
18681 reports time overflow. See
18682 <http://lists.gnu.org/archive/html/emacs-devel/2011-03/msg00470.html>.
18683 * deps.mk (editfns.o): Depend on ../lib/intprops.h.
