24 * fileio.c (check_existing): New function.
25 (make_temp_name, Ffile_exists_p, Ffile_writable_p): Call it
26 instead of calling 'stat', when what's needed is to check whether
27 a file exists. This avoids expensive system calls on MS-Windows.
30 * w32.c (init_environment): Call 'check_existing' instead of
33 * lread.c (openp) [WINDOWSNT]: Call 'access' instead of 'stat' to
34 determine whether a file exists and is not a directory.

121 Use bool for boolean.
122 * keyboard.c (timers_run, swallow_events)
123 (detect_input_pending_run_timers):
124 * process.c (wait_reading_process_output):
125 Use unsigned for counter where wraparound-on-overflow is desired,
126 since unsigned is guaranteed to have that behavior and signed is not.
127 (read_char): Use ptrdiff_t for string length.
128 (get_input_pending): Remove first argument, since it was always
129 the same pointer-to-int (now pointer-to-boolean) &input_pending,
130 and behave as if it had that value. Return new value of
131 input_pending. All callers changed.
132 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
133 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's

153 Clean out old termopts cruft.
154 * termopts.h (flow_control, meta_key): Remove unused decls.
155 * dispnew.c, indent.c, nsterm.m, term.c, xsettings.c, xsmfns.c:
156 Don't include termopts.h.
158 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>
160 * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers.
162 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>

173 2012-10-09 Eli Zaretskii <eliz@gnu.org>
175 * w32fns.c (w32_last_error): Change the return value to DWORD, to
176 match what GetLastError returns. Explain why the function is
179 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
180 'is_tooltip_frame', to avoid confusion with its global namesake.
182 2012-10-08 Daniel Colascione <dancol@dancol.org>
184 * xdisp.c (start_hourglass): Call w32_note_current_window when
185 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
186 build that caused Emacs to display the hourglass cursor forever.
188 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
189 which is broken under remote desktop, calculate the number of
190 colors available for a display based on the display's number of
191 planes and number of bits per pixel per plane. (bug#10397).
193 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
195 * nsfont.m (Vfonts_in_cache): New variable.
196 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
197 are used. Add cached fonts to Vfonts_in_cache.
198 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
200 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
202 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
204 (FONT_H): Define after FRAME_H.
205 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
208 * w32term.c: Remove leftover declaration of keyboard_codepage.
210 2012-10-08 Eli Zaretskii <eliz@gnu.org>
212 * makefile.w32-in (FONT_H): Add $(FRAME_H).
213 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
214 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
215 (GLOBAL_SOURCES): Add cygw32.c.
216 ($(BLD)/unexw32.$(O)):

228 2012-10-08 Daniel Colascione <dancol@dancol.org>
230 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
231 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
232 accidental message numbering hole. Change other messages to
235 * w32select.h (HAVE_W32SELECT): Remove.
237 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
238 w32common.h instead of w32heap.h
240 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)

248 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
249 (w32_minor_version, w32_build_number, w32_subtype): Remove
250 duplicate definitions.
252 * w32fns.c: Include w32common.h; include w32heap.h only in
255 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
256 Use `report_file_error' instead of `error' in order to better
257 inform users of what went wrong. Increase NTGUI_UNICODE file
258 dialog box file name length to 32k, the maximum allowed by the NT
261 * w32common.h: New file.
262 (ROUND_UP, ROUND_DOWN, get_page_size)
263 (get_allocation_unit, get_processor_type, get_w32_major_version)
264 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
265 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
266 (OS_NT, os_subtype, cache_system_info): Move here.
268 * unexw32.c, unexcw.c: Include w32common.h.
270 * emacs.c (main): Use (defined (WINDOWSNT) || defined
271 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
272 to call syms_of_w32select.
274 * cygw32.h: Remove obsolete EXFUN declarations.
276 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
278 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
279 of w32inevt.o from SOME_MACHINE_OBJECTS.
281 2012-10-08 Daniel Colascione <dancol@dancol.org>
283 * image.c: Permanent fix for JPEG compilation issue --- limit
284 jpeglib `boolean' redefinition to Cygwin builds.
286 2012-10-08 Eli Zaretskii <eliz@gnu.org>
288 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
290 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
293 2012-10-08 Daniel Colascione <dancol@dancol.org>
295 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
296 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
297 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
298 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
299 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
300 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
301 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
302 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
303 now a supported configuration.
305 * Makefile.in: consolidate image variables into LIBIMAGE; add
306 W32_OBJ and W32_LIBS. Compile new files.
309 (_DebPrint) declare tracing facility for W32 debugging. We need
310 to unify tracing later.
312 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
313 unconditional use of W32 Unicode functions. Cygwin runs only on
314 100% Unicode operating systems.
316 * cygw32.c: New file. Define Cygwin-specific facilities.
317 (Fcygwin_convert_path_to_windows)
318 (Fcygwin_convert_path_from_windows): New user functions for
319 accessing Cygwin path-munging routines.
321 * cygw32.h: New file.
322 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
323 UTF-16LE strings temporarily inside non-Lisp-visible string
326 (w32_strerror): Just what it says on the tin.
328 * emacs.c: Make the NS fork-then-exec code for daemon-launching
329 also run for Cygwin; both systems have the same problem with using
330 GUI facilities in a forked child. Also call syms_of_cygw32,
331 syms_of_w32select in correct places.
333 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
334 needs fork-then-exec for daemon launching.
336 * font.h: Include frame.h.
338 * image.c: Use the image library cache machinery only when we're
339 compiling for native WINDOWSNT; Cygwin can use shared libraries
340 like any other Unixlike system.
342 * keyboard.c: Clarify a comment regarding the input loop.
344 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
345 functions directly instead of trying to detect at runtime that our
346 host operating system supports them. We make this change for two
347 reasons: Cygwin lacks support for the multibyte character
348 conversion functions used by the legacy menu code, and Cygwin
349 never needs to rely on non-Unicode APIs.
351 * unexw32.c (hinst): Declare extern.
353 * w32.c: Change header order;
354 (w32_strerror): Move to w32fns.c because we need it for
355 non-WINDOWSNT builds.
357 * w32.h: Add #error macro to make sure we don't include w32.h for
358 Cygwin builds. Remove w32select declarations.
360 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
361 w32fns.c. w32console.c is WINDOWSNT-only.
363 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
364 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
366 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
367 (w32_major_version, w32_minor_version, w32_build_number)
368 (os_subtype, sound_type): Define here
369 (w32_defined_color): Make color parameter const for consistency
370 with other _defined_color functions.
371 (w32_createwindow): Unconditionally call w32_init_class instead of
372 doing so only when hprevinst is non-NULL. Plumbing hprevinst
373 through the code is complex and unnecessary because class
374 registration is practically free.
375 (w32_name_of_message): New EMACSDEBUG-only function.
376 (Fset_message_beep): Move here
377 (Fx_open_connection): Require that the display name for Windows be
378 "w32" for consistency, emacsclient disambiguation, and maybe, one
379 day, multi-window-system support.
380 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
381 Cygwin files for W32 GUI facilities, since these clearly don't
384 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
385 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
386 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
387 (w32_last_error): Remove.
389 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
391 * w32heap.c (syspage_mask): Declare here.
392 (cache_system_info): Remove.
394 * w32inevt.c (faked_key): Define globally, not statically.
395 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
396 (w32_console_toggle_lock_key): Move to w32fns.c.
398 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
400 * w32proc.c (_DebPrint): Move to w32fns.c.
401 * w32select.c: Include string.h, stdio.h for Cygwin.
402 * w32select.h: New File.
404 * w32term.c: Include io.h for non-CYGWIN builds; needed for
406 (w32_message_fd): New variable. Under Cygwin, holds the file
407 descriptor the system used to tell us about pending thread
410 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
411 that prevented compilation under non-WINDOWSNT systems.
413 (w32_initialize): Open /dev/windows and assign it to
414 w32_message_fd. Provide w32 feature.
416 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
417 (WM_EMACS_INPUT_READY): add.
418 (prepend_msg, w32_message_fd): Declare globally.
421 (keyboard_handle): Use only when WINDOWSNT.
422 (notify_msg_ready): New function. Posts a message to the main
423 thread's message queue under CYGWIN, which wakes up the main
424 thread from select(2) by making the /dev/windows file descriptor
425 ready. Under WINDOWSNT, it sets an event the same way the old
428 (post, prepend_msg): Actually call notify_msg_ready instead of
429 setting the input event directly.
431 2012-10-07 Eli Zaretskii <eliz@gnu.org>
433 * ralloc.c (relinquish): If a heap is ready to be relinquished,
434 but it still has blocs in it, don't return it to the system,
435 instead of aborting. (Bug#12402)
437 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
439 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
441 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
442 MAC_OS_X_VERSION_10_6.

453 MAC_OS_X_VERSION_10_2.
455 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
457 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
458 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
460 * nsterm.m (ns_in_resize): Remove (Bug#12479).

462 (ns_clear_frame, sendEvent, windowDidResize, drawRect:): Remove
464 (ns_clear_frame_area): Remove resize handle code.
466 * nsfns.m (ns_in_resize): Remove.
467 (x_set_icon_name, ns_set_name, ns_set_name_as_filename): Remove
470 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
472 Improve sys_siglist detection.
473 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
474 defined as a macro, as is done in Solaris.
475 (sys_siglist_entries): New macro.
476 (save_strsignal): Use it.
477 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
478 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
480 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
482 * nsfns.m (Fx_create_frame): Call x_default_parameter with
483 fullscreen/Fullscreen.

490 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
491 (windowDidResize:): Check for correct window if old style fullscreen.
492 Capitalize word in comment. Remove incorrect comment.
493 (initFrameFromEmacs:): tbar_height renamed tibar_height.
494 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
495 error in drawing background.
496 (toggleFullScreen:): Remove comment. Rearrange calls.
497 Set toolbar values to zero, save old height in tobar_height.
498 Restore tool bar height when leaving fullscreen.
499 (canBecomeMainWindow): New function.
501 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
503 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
505 2012-10-05 Eli Zaretskii <eliz@gnu.org>
507 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
509 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
510 that time stamps of directories could also be changed. Don't
511 request the too broad GENERIC_WRITE, only the more restrictive
512 FILE_WRITE_ATTRIBUTES access rights.
514 * fileio.c (Fset_file_times): Special-case ignoring errors for
515 directories only on MSDOS, not on MS-Windows.
517 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
519 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
521 2012-10-04 Eli Zaretskii <eliz@gnu.org>
523 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
524 see whether CreateFile failed.
526 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
528 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
529 to avoid similar races.
530 * keyboard.c (pending_signals): Now bool, not int.
532 Port timers to OpenBSD, plus check for timer failures.
533 OpenBSD problem reported by Han Boetes.
534 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
536 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
537 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
538 like OpenBSD, which has timer_settime but does not declare it.
539 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
540 whether to use itimerspec-related primitives. All uses of
541 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
543 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
545 * profiler.c (handle_profiler_signal): Fix a malloc race
546 that caused Emacs to hang on Fedora 17 when profiling Lisp.
548 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
550 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
552 2012-10-02 Eli Zaretskii <eliz@gnu.org>
554 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
555 consistent with the change in return value of 'safe_strsignal'.
557 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
559 Prefer plain 'static' to 'static inline' (Bug#12541).

567 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
568 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
569 Now 'static', not 'static inline'.
571 Count overruns when profiling; change units to ns.
572 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
573 Give extra weight to samples after overruns, to attempt to count
574 the time more accurately.
575 (setup_cpu_timer): Change sampling interval units from ms to ns, since
576 the underlying primitives nominally do ns.
577 (Fprofiler_cpu_start): Document the change. Mention that
578 the sampling intervals are only approximate.
580 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
582 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
584 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
585 case for the special 0 coding-system.
587 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
588 (Fmake_overlay): Remove redundant tests.
589 (fix_start_end_in_overlays): Remove redundant recentering.
591 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
593 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
596 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
598 Fix a malloc race condition involving strsignal.
599 A signal can arrive in the middle of a malloc, and Emacs's signal
600 handler can invoke strsignal, which can invoke malloc, which is
601 not portable. This race condition bug makes Emacs hang on GNU/Linux.
602 Fix it by altering the signal handler so that it does not invoke
604 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
605 * process.c (status_message): Use const pointer, in case strsignal
606 is #defined to safe_strsignal.
607 * sysdep.c (sys_siglist, init_signals): Always define and
608 initialize a substitute sys_siglist if the system does not define
609 one, even if HAVE_STRSIGNAL.
610 (safe_strsignal): Rename from strsignal. Always define,
611 using sys_siglist. Return a const pointer.
612 * syssignal.h (safe_strsignal): New decl.
613 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
615 2012-10-01 Eli Zaretskii <eliz@gnu.org>
617 * w32proc.c (timer_loop): Fix code that waits for timer
618 expiration, to avoid high CPU usage.
620 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
622 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
623 (sweep_weak_table): Remove redundant prototypes.
625 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
627 * emacs.c: Move the inclusion of TERM_HEADER after including
628 windows.h on WINDOWSNT. This avoids compilation problems with
631 2012-10-01 Eli Zaretskii <eliz@gnu.org>
633 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
634 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
635 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
636 as the previous version used 'void *'.
638 * ralloc.c (ROUNDUP): Fix last change.
639 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
642 * w32proc.c <disable_itimers>: New static flag.
643 (init_timers): Initialize it to zero, after creating the critical
644 sections used by the timer threads.
645 (term_timers): Set to 1 before deleting the critical sections.
646 (getitimer, setitimer): If disable_itimers is non-zero, return an
647 error indication without doing anything. Reported by Fabrice
648 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
649 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
651 [!HAVE_SETITIMER]: Behave as the previous version that didn't
654 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
655 term_ntproc after all the other bookkeeping, to get timers working
658 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
660 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
661 Suggested by Juri Linkov in
662 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
664 Prefer plain 'static' to 'static inline' (Bug#12541).
665 With static functions, modern compilers inline pretty well by
666 themselves; advice from programmers often hurts as much as it helps.
667 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
668 this change shrinks the text size of the Emacs executable by 1.1%
669 without affecting CPU significantly in my benchmark.

965 cpu_log is a hash-table if garbage collecting, since it
966 doesn't matter in that case.
967 (deliver_profiler_signal): Rename from sigprof_handler,
968 for consistency with other handlers.
969 (setup_cpu_timer): New function, with much of what used to be in
970 Fprofiler_cpu_start. Check for out-of-range argument.
971 Prefer timer_settime if available, and prefer
972 thread cputime clocks, then process cputime clocks, then
973 monotonic clocks, to the old realtime clock. Use make_timeval
974 to round more-correctly when falling back to setitimer.
975 (Fprofiler_cpu_start): Use it.
976 (Fprofiler_cpu_stop): Prefer timer_settime if available.
977 Don't assume that passing NULL as the 2nd argument of setitimer
978 is the same as passing a pointer to all-zero storage.
979 Ignore SIGPROF afterwards.
980 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
981 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
982 non-fatal signal handlers. Ignore SIGPROF on startup.
983 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
984 in profiler.c, since sysdep.c now uses it.
986 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.
987 Suggested by Eli Zaretskii in
988 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.

1001 (Fbacktrace_frame): Adjust accordingly.
1003 2012-09-28 Glenn Morris <rgm@gnu.org>
1005 * eval.c (Frun_hook_with_args, Frun_hook_with_args_until_success)
1006 (Frun_hook_with_args_until_failure): Doc fixes.
1008 2012-09-28 Eli Zaretskii <eliz@gnu.org>

1024 * Makefile.in (LIB_TIMER_TIME): New macro.
1026 * atimer.c (alarm_timer, alarm_timer_ok, set_alarm, init_atimer):

1038 2012-09-26 Paul Eggert <eggert@cs.ucla.edu>
1040 * character.h (MAYBE_UNIFY_CHAR): Remove.
1041 * charset.c, charset.h (maybe_unify_char): Now static.
1042 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
1043 Since this stuff is now private to charset.c, there's no need for
1044 a public macro and no need to inline by hand.

1047 Stefan Monnier <monnier@iro.umontreal.ca>
1048 Juanma Barranquero <lekktu@gmail.com>

1075 * makefile.w32-in ($(BLD)/callproc.$(O)): Update dependencies.
1077 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>
1079 Prefer POSIX timers if available.
1080 They avoid a race if the timer is too close to the current time.
1081 * atimer.c (alarm_timer, alarm_timer_ok) [SIGEV_SIGNAL]: New static vars.
1082 (set_alarm) [SIGEV_SIGNAL]: Use POSIX timers if available.
1083 (init_atimer) [SIGEV_SIGNAL]: Initialize them.
1085 2012-09-25 Eli Zaretskii <eliz@gnu.org>

1108 * w32.h (Vlibrary_cache): Do not declare.
1110 2012-09-25 Eli Zaretskii <eliz@gnu.org>
1112 * w32proc.c (sys_signal): Handle all signals defined by the
1113 MS-Windows runtime, not just SIGCHLD. Actually install the signal
1114 handlers for signals supported by Windows. Don't override
1115 term_ntproc as the handler for SIGABRT.
1116 (sigaction): Rewrite to call sys_signal instead of duplicating its
1118 (sys_kill): Improve commentary.
1120 * w32.c (term_ntproc): Accept (and ignore) one argument, for
1121 consistency with a signature of a signal handler. All callers
1123 (init_ntproc): Accept an argument DUMPING. If dumping, don't
1124 install term_ntproc as a signal handler for SIGABRT, as that
1125 should be done by the dumped Emacs.
1127 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
1129 * w32select.c (term_w32select): Protect against repeated
1130 invocation by setting clipboard_owner to NULL after calling
1133 * emacs.c (shut_down_emacs, main): Adapt the calls to init_ntproc
1134 and term_ntproc to their modified signatures.
1136 * character.c (char_string, string_char): Remove calls to
1137 MAYBE_UNIFY_CHAR. See the discussion starting at
1138 http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00433.html
1141 2012-09-25 Chong Yidong <cyd@gnu.org>
1143 * xdisp.c (mode_line_inverse_video): Delete obsolete variable.
1145 2012-09-24 Stefan Monnier <monnier@iro.umontreal.ca>
1147 * bytecode.c (exec_byte_code): Signal an error instead of aborting,
1148 when encountering an unknown bytecode.
1150 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
1152 image.c, indent.c: Use bool for booleans.
1153 * dispextern.h (struct image_type): Members valid_p, load, init
1154 now return bool, not int. All uses changed.
1155 * image.c: Omit unnecessary static decls.
1156 (x_create_bitmap_mask, x_build_heuristic_mask):
1157 Return void, not int, since callers don't care about the return value.

1192 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
1194 Move pid_t related decls out of lisp.h.
1195 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
1196 (interruptible_wait_for_termination):
1197 Move these decls from lisp.h to syswait.h, since they use pid_t.
1198 Needed on FreeBSD; see Herbert J. Skuhra in
1199 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
1200 * callproc.c: Include syswait.h.

1220 Use bool for boolean.
1221 * gtkutil.c (xg_update_frame_menubar):

1246 2012-09-23 Eli Zaretskii <eliz@gnu.org>
1248 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
1249 fatal_error_backtrace.
1251 * w32proc.c (sys_kill): Undo last change: don't do anything when
1252 invoked to deliver SIGABRT to our own process. This is now
1253 handled by emacs_raise.
1255 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
1257 * w32term.c (w32_read_socket): Remove leftover reference to
1258 interrupt_input_pending.
1260 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
1262 Do not use SA_NODEFER.
1263 Problem reported by Dani Moncayo in
1264 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
1266 * sysdep.c (emacs_abort): Do not reset signal handler.
1267 * emacs.c (terminate_due_to_signal): Reset signal handler here.
1268 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
1269 wanted even on POSIXish hosts, and it doesn't work on Windows.
1271 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
1273 * xterm.c (x_term_init): Call fixup_locale before and after calling
1274 gtk_init (Bug#12392).
1276 2012-09-23 Chong Yidong <cyd@gnu.org>
1278 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
1279 Vdynamic_library_alist.
1281 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
1282 (Fgnutls_available_p): Caller changed.
1284 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
1285 (Flibxml_parse_xml_region): Likewise.
1287 * dispextern.h (struct image_type): Remove arg from init function.
1289 * image.c (Finit_image_library, lookup_image_type)
1290 (define_image_type): Remove now-unneeded second arg.
1291 (init_xpm_functions, init_png_functions, init_jpeg_functions)
1292 (init_tiff_functions, init_gif_functions, init_svg_functions):
1293 Arglist and w32_delayed_load calling convention changed.
1294 (gs_type): Remove init_gs_functions; there is no such function.
1295 (valid_image_p, make_image): Fix caller to lookup_image_type.
1297 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
1299 Simplify and avoid signal-handling races (Bug#12471).
1301 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
1302 Avoid recursive loop if there's a fatal error in the function itself.
1303 * atimer.c (pending_atimers):
1304 * blockinput.h: Don't include "atimer.h"; no longer needed.
1305 (interrupt_input_pending): Remove. All uses removed.
1306 pending_signals now counts both atimers and ordinary interrupts.
1307 This is less racy than having three separate pending-signal flags.
1308 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
1310 Rename from their upper-case counterparts BLOCK_INPUT,
1311 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
1312 INPUT_BLOCKED_P, and turn into functions. All uses changed.
1313 This makes it easier to access volatile variables more accurately.
1314 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
1315 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
1316 that's more reliable if the code is buggy and sets
1317 interrupt_input_blocked to a negative value. All uses changed.
1318 * atimer.c (deliver_alarm_signal):
1319 Remove. No need to deliver this to the parent; any thread can
1320 handle this signal now. All uses replaced by underlying handler.
1321 * atimer.c (turn_on_atimers):
1322 * dispnew.c (handle_window_change_signal):
1323 * emacs.c (handle_danger_signal):
1324 * keyboard.c (kbd_buffer_get_event):
1325 Don't reestablish signal handler; not needed with sigaction.
1326 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
1328 Rework to avoid unnecessary accesses to volatile variables.
1329 (UNBLOCK_INPUT_TO): Now a function.
1330 (totally_unblock_input, unblock_input): New decls.
1331 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
1332 (init_data): Remove. Necessary stuff now done in init_signal.
1333 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
1334 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
1335 (fatal_error_code): Remove; no longer needed.
1336 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
1337 it doesn't always backtrace. All uses changed. No need to reset
1338 signal to default, since sigaction and/or die does that for us now.
1339 Use emacs_raise (FOO), not kill (getpid (), FOO).
1340 (main): Check more-accurately whether we're dumping.
1341 Move fatal-error setup to sysdep.c
1342 * floatfns.c: Do not include "syssignal.h"; no longer needed.
1343 * gtkutil.c (xg_get_file_name, xg_get_font):
1344 Remove no-longer-needed signal-mask manipulation.
1345 * keyboard.c, process.c (POLL_FOR_INPUT):
1346 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
1347 * keyboard.c (read_avail_input): Remove.
1348 All uses replaced by gobble_input.
1349 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
1350 (kbd_buffer_store_event_hold, gobble_input):
1351 (record_asynch_buffer_change) [USABLE_SIGIO]:
1352 (store_user_signal_events):
1353 No need to mess with signal mask.
1354 (gobble_input): If blocking input and there are terminals, simply
1355 set pending_signals to 1 and return. All hooks changed to not
1356 worry about whether input is blocked.
1357 (process_pending_signals): Clear pending_signals before processing
1358 them, in case a signal comes in while we're processing.
1359 By convention callers now test pending_signals before calling us.
1360 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
1361 New functions, to support changes to blockinput.h.
1362 (handle_input_available_signal): Now extern.
1363 (reinvoke_input_signal): Remove. All uses replaced by
1365 (quit_count): Now volatile, since a signal handler uses it.
1366 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
1367 All callers changed. Block SIGINT only if not already blocked.
1368 Clear sigmask reliably, even if Fsignal returns, which it can.
1369 Omit unnecessary accesses to volatile var.
1370 (quit_throw_to_read_char): No need to restore sigmask.
1371 * keyboard.c (gobble_input, handle_user_signal):
1372 * process.c (wait_reading_process_output):
1373 Call signal-handling code rather than killing ourselves.
1374 * lisp.h: Include <float.h>, for...
1375 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
1376 (pending_signals): Now volatile.
1377 (syms_of_data): Now const if IEEE floating point.
1378 (handle_input_available_signal) [USABLE_SIGIO]:
1379 (terminate_due_to_signal, record_child_status_change): New decls.
1380 * process.c (create_process): Avoid disaster if memory is exhausted
1381 while we're processing a vfork, by tightening the critical section
1383 (send_process_frame, process_sent_to, handle_pipe_signal)
1384 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
1386 (send_process): No need for setjmp/longjmp any more, since the
1387 SIGPIPE stuff is now gone. Instead, report an error if errno
1389 (record_child_status_change): Now extern. PID and W are now args.
1390 Return void, not bool. All callers changed.
1391 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
1392 Remove. All uses removed. This bug should be fixed now in a
1394 (wait_for_termination_1): Use waitpid rather than sigsuspend,
1395 and record the child status change directly. This avoids the
1396 need to futz with the signal mask.
1397 (process_fatal_action): Move here from emacs.c.
1398 (emacs_sigaction_flags): New function, containing
1399 much of what used to be in emacs_sigaction_init.
1400 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
1401 caught by emacs, to make races less likely.
1402 (deliver_process_signal): Rename from handle_on_main_thread.
1404 (BACKTRACE_LIMIT_MAX): Now at top level.
1405 (thread_backtrace_buffer, threadback_backtrace_pointers):
1407 (deliver_thread_signal, deliver_fatal_thread_signal):
1408 New functions, for more-accurate delivery of thread-specific signals.
1409 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
1410 (deliver_arith_signal): Handle in this thread, not
1411 in the main thread, since it's triggered by this thread.
1412 (maybe_fatal_sig): New function.
1413 (init_signals): New arg DUMPING so that we can be more accurate
1414 about whether we're dumping. Caller changed.
1415 Treat thread-specific signals differently from process-general signals.
1416 Block all signals while handling fatal error; that's safer.
1417 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
1419 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
1420 Ignore SIGPIPE unless batch.
1421 (emacs_backtrace): Output backtrace for the appropriate thread,
1422 which is not necessarily the main thread.
1423 * syssignal.h: Include <stdbool.h>.
1424 (emacs_raise): New macro.
1425 * xterm.c (x_connection_signal): Remove; no longer needed
1426 now that we use sigaction.
1427 (x_connection_closed): No need to mess with sigmask now.
1428 (x_initialize): No need to reset SIGPIPE handler here, since
1429 init_signals does this for us now.
1431 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
1433 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
1434 background rect may be larger (Bug#12245).
1436 2012-09-23 Chong Yidong <cyd@gnu.org>
1438 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
1440 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
1442 * .gdbinit: Just stop at fatal_error_backtrace.
1443 See Stefan Monnier's request in
1444 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
1445 Remove no-longer-used query of system type.
1447 2012-09-22 Chong Yidong <cyd@gnu.org>
1449 * search.c (Freplace_match): Doc fix (Bug#12325).
1451 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
1453 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
1454 (Fline_end_position): Doc fix.
1456 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
1458 2012-09-22 Chong Yidong <cyd@gnu.org>
1460 * dispextern.h (struct image_type): Add new slot, storing a type
1461 initialization function.
1463 * image.c (define_image_type): Call the image initializer function
1464 if it is defined. Arguments and return value changed.
1465 (valid_image_p, make_image): Callers changed.
1466 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
1467 (gif_type, imagemagick_type, svg_type, gs_type):
1468 Add initialization functions.
1469 (Finit_image_library): Call lookup_image_type.
1470 (CHECK_LIB_AVAILABLE): Macro deleted.
1471 (lookup_image_type): Call define_image_type here, rather than via
1472 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
1473 (syms_of_image): Move define_image_type calls for xbm_type and
1474 pbm_type to lookup_image_type.
1476 2012-09-22 Eli Zaretskii <eliz@gnu.org>
1478 * keyboard.c (timer_check_2): Move calculation of 'timers' and
1479 'idle_timers' from here ...
1480 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
1481 lists, to avoid infloops when the timer does something stupid,
1482 like reinvoke itself with the same or smaller time-out.
1485 2012-09-22 Martin Rudalics <rudalics@gmx.at>
1487 * window.c (Fsplit_window_internal): Handle only Qt value of
1488 Vwindow_combination_limit separately.
1489 (Qtemp_buffer_resize): New symbol.
1490 (Vwindow_combination_limit): New default value.
1493 2012-09-22 Eli Zaretskii <eliz@gnu.org>
1495 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
1496 the new overlay string. (Bug#10159)
1498 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
1500 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
1501 or that fprintf is async-signal-safe. POSIX doesn't require
1504 2012-09-22 Chong Yidong <cyd@gnu.org>
1506 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
1509 2012-09-22 Kenichi Handa <handa@gnu.org>
1511 * composite.c (composition_reseat_it): Handle the case that a
1512 grapheme cluster is not covered by a single font (Bug#12352).
1514 2012-09-21 Chong Yidong <cyd@gnu.org>
1516 * image.c (define_image_type): Avoid adding duplicate types to
1517 image_types (Bug#12463). Suggested by Jörg Walter.
1519 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1521 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
1522 (print_load_command_name): Add case LC_DATA_IN_CODE.
1523 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
1525 2012-09-21 Glenn Morris <rgm@gnu.org>
1527 * eval.c (Frun_hook_with_args_until_success)
1528 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
1530 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
1532 * fileio.c (Ffile_selinux_context): Only call freecon when
1533 lgetfilecon succeeded.
1534 (Fset_file_selinux_context): Likewise. (Bug#12444)
1536 2012-09-21 Eli Zaretskii <eliz@gnu.org>
1538 * xdisp.c (try_window_reusing_current_matrix): Under bidi
1539 reordering, locate the cursor by calling set_cursor_from_row; if
1540 that fails, clear the desired glyph matrix before returning a
1541 failure indication to the caller. Fixes leaving garbled display
1542 when fast scrolling with a down-key. (Bug#12403)
1543 (compute_stop_pos_backwards): Fix a typo that caused crashes while
1544 scrolling through multibyte text.
1546 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
1548 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
1549 calling mark_vectorlike since that's the one that marks the window.
1550 (mark_discard_killed_buffers): Mark the final cdr.
1551 * window.h (struct window): Move prev/next_buffers to the
1552 non-standard fields.
1553 * window.c (make_window): Initialize prev/next_buffers manually.
1555 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
1557 Omit unused arg EXPECTED from socket hooks.
1558 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
1559 * nsterm.m (ns_term_init):
1560 * termhooks.h (struct terminal.read_socket_hook):
1561 * w32inevt.c (w32_console_read_socket):
1562 * w32term.c (w32_read_socket):
1563 * xterm.c (XTread_socket):
1564 Omit unused arg EXPECTED. All callers changed.
1565 (store_user_signal_events): Return void, not int, since callers no
1566 longer care about the return value. All uses changed.
1568 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
1570 * w32gui.h (XParseGeometry): Do not declare.
1572 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
1574 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
1575 Ignore 'expected'. See Eli Zaretskii in
1576 <http://bugs.gnu.org/12471#8> (last line).
1578 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
1579 (XParseGeometry): Now static. Substitute extremal values for
1580 values that are out of range.
1582 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
1584 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
1586 * nsfns.m (XParseGeometry): Remove.
1587 (Fx_create_frame): Call x_set_offset to correctly interpret
1588 top_pos in geometry.
1590 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
1591 (Fx_parse_geometry): If there is a space in string, call
1592 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
1594 2012-09-17 Eli Zaretskii <eliz@gnu.org>
1596 * search.c (scan_buffer): Use character positions in calls to
1597 region_cache_forward and region_cache_backward, not byte
1598 positions. (Bug#12196)
1600 * w32term.c (w32_read_socket): Set pending_signals to 1, like
1601 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
1603 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
1604 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
1605 emacs_blocked_malloc, now deleted.
1607 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
1609 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
1610 The workaround was for improving performance on Solaris 2.4, but
1611 is getting in the way now. Emacs will still work if someone is
1612 still running Solaris 2.4 in a museum somewhere; Sun dropped
1613 support for Solaris 2.4 in 2003.
1614 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
1615 * process.c (create_process) [HAVE_WORKING_VFORK]:
1616 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
1617 since Emacs no longer uses vfork on that platform.
1619 2012-09-17 Glenn Morris <rgm@gnu.org>
1621 * emacs.c: Use COPYRIGHT.
1623 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
1625 Remove configure's --without-sync-input option (Bug#12450).
1626 When auditing signal-handling in preparation for cleaning it up,
1627 I found that SYNC_INPUT has race conditions and would be a real
1628 pain to fix. Since it's an undocumented and deprecated
1629 configure-time option, now seems like a good time to remove it.
1630 Also see <http://bugs.gnu.org/11080#16>.
1631 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
1632 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
1633 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
1634 (malloc_hysteresis):
1635 (check_depth) [XMALLOC_OVERRUN_CHECK]:
1636 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
1637 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
1638 (dont_register_blocks, bytes_used_when_reconsidered)
1639 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
1640 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
1641 [!SYSTEM_MALLOC && !SYNC_INPUT]:
1642 Remove. All uses removed.
1643 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
1644 implementation, one that depends on whether the new macro
1645 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
1647 * atimer.c (run_timers, handle_alarm_signal):
1648 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
1649 (handle_async_input, process_pending_signals)
1650 (handle_input_available_signal, init_keyboard):
1651 * nsterm.m (ns_read_socket):
1652 * process.c (wait_reading_process_output):
1653 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
1654 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
1656 * xterm.c (XTread_socket):
1658 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
1659 * eval.c (handling_signal): Remove. All uses removed.
1660 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
1661 All uses replaced with the SYNC_INPUT version.
1662 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
1664 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
1667 * font.c (Ffont_shape_gstring): Remove unused local.
1669 2012-09-16 Glenn Morris <rgm@gnu.org>
1671 * Makefile.in (clean): No longer run nextstep's clean.
1673 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
1675 (ns-app): Move here from ns.mk, and simplify.
1676 (clean): Simplify nextstep entry.
1677 * ns.mk: Remove file.
1679 2012-09-17 Kenichi Handa <handa@gnu.org>
1681 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
1682 not covert the last few charactes.
1684 2012-09-16 Kenichi Handa <handa@gnu.org>
1686 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
1687 here, but just check the validity of glyphs in the glyph-string.
1689 2012-09-16 Martin Rudalics <rudalics@gmx.at>
1691 * window.c (Fwindow_parameter, Fset_window_parameter):
1692 Accept any window as argument (Bug#12452).
1694 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
1696 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
1697 to ns_term_init to avoid memory leak.
1699 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
1700 explicit retain/release.
1701 (ns_term_init): Only allow one display. Initialize outerpool and
1704 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
1706 Port _setjmp fix to POSIXish hosts as well as Microsoft.
1707 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
1708 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
1709 the Microsoft problem in a different way, by altering ../nt/config.nt.
1711 2012-09-15 Eli Zaretskii <eliz@gnu.org>
1726 * w16select.c: Remove inclusion of setjmp.h, as it is now included
1727 by lisp.h. This completes removal of setjmp.h inclusion
1728 erroneously announced in the previous commit. (Bug#12446)
1730 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
1733 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
1734 not defined as a macro. The latter happens on MS-Windows.
1737 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
1739 Port better to POSIX hosts lacking _setjmp (Bug#12446).
1740 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
1741 Some instances of '#include <setjmp.h>' removed, if the
1742 only reason for the instance was because "lisp.h" was included.
1743 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
1744 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
1745 and _longjmp with the new symbols. Emacs already uses _setjmp if
1746 available, so this change affects only POSIXish hosts that have
1747 sigsetjmp but not _setjmp, such as some versions of Solaris and
1748 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
1749 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
1750 (png_load_body) [HAVE_PNG]:
1751 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
1752 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
1753 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
1754 since PNG requires jmp_buf. This is the only exception to the
1755 general rule that we now use sys_setjmp and sys_longjmp.
1756 This exception is OK since this code does not change the signal
1757 mask or longjmp out of a signal handler.
1759 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
1761 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
1762 Include "syssignal.h", for 'main_thread'.
1764 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
1766 Avoid out-of-range marker position (Bug#12426).
1767 * insdel.c (replace_range, replace_range_2):
1768 Adjust markers before overlays, as suggested by comments.
1769 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
1770 Remove redundant check before calling offset_intervals.
1772 2012-09-14 Martin Rudalics <rudalics@gmx.at>
1774 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
1775 current buffer (Bug#12387).
1777 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
1779 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
1781 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
1783 Use a more backwards-compatible timer format (Bug#12430).
1784 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
1785 vector element, not from the 4th, since PSECS is now at the end.
1786 (Fcurrent_idle_time): Doc fix.
1788 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
1790 Function to mark objects and remove killed buffers at once.
1791 * alloc.c (discard_killed_buffers): Rename to ...
1792 (mark_discard_killed buffers) ... new name. Add marking
1793 of remaining objects. Fix comment. Adjust users.
1794 (mark_object): Do not touch frame buffer lists here.
1795 * frame.c (delete_frame): Reset frame buffer lists here.
1797 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
1799 Better workaround for GNOME bug when --enable-gcc-warnings.
1800 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
1801 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
1802 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
1804 Simplify SIGIO usage (Bug#12408).
1805 The code that dealt with SIGIO was crufty and confusing, e.g., it
1806 played tricks like "#undef SIGIO" but these tricks were not used
1807 consistently. Simplify mostly by not #undeffing standard symbols,
1808 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
1809 or not as we please) rather than "defined SIGIO" (standard symbol
1810 that we probably shouldn't #undef).
1811 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
1812 Modules that need it can include it.
1813 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
1814 * dispextern.h (ignore_sigio): New decl.
1815 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
1816 unconditionally, since it's now a no-op if !USABLE_SIGIO.
1817 * emacs.c (shut_down_emacs):
1818 * keyboard.c (kbd_buffer_store_event_hold):
1819 Use ignore_sigio rather than invoking 'signal' directly.
1820 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
1822 (FIONREAD, SIGIO): Do not #undef.
1823 (tty_read_avail_input): Use #error rather than a syntax error.
1824 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
1825 for I_PIPE, used by SETUP_SLAVE_PTY.
1826 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
1827 * sysdep.c (croak): Remove; no longer needed. This bit of
1828 temporary code, with Fred N. Fish's comment that it's temporary,
1829 has been in Emacs since at least 1992!
1830 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
1831 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
1832 * syssignal.h (croak): Remove decl.
1833 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
1834 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
1835 now that we're termios-only.
1836 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
1837 * term.c (dissociate_if_controlling_tty): Use #error rather than
1840 Work around GCC and GNOME bugs when --enable-gcc-warnings.
1841 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
1842 to work around GNOME bug 683906.
1843 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
1844 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
1845 This works around GCC bug 54561.
1847 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
1849 More fixes for 'volatile' and setjmp/longjmp.
1850 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
1851 * image.c (struct png_load_context) [HAVE_PNG]: New type.
1852 (png_load_body) [HAVE_PNG]:
1853 (jpeg_load_body) [HAVE_JPEG]:
1854 New function, with most of the old parent function's body.
1855 (png_load) [HAVE_PNG]:
1856 (jpeg_load) [HAVE_JPEG]:
1857 Invoke the new function, to avoid longjmp munging our locals.
1858 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
1859 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
1860 longjmp is passed 2, as the C standard doesn't guarantee this.
1861 Instead, store the failure code into mgr->failure_code.
1863 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
1865 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
1866 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
1867 (syms_of_keyboard): Remove support for unread-command-char.
1869 2012-09-12 Eli Zaretskii <eliz@gnu.org>
1871 * w32proc.c (sys_kill): If PID is our process ID and the signal is
1872 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
1873 violation. (Bug#12426)
1875 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
1877 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
1879 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
1881 * eval.c: Add `inhibit-debugger'.
1882 (Qinhibit_debugger): New symbol.
1883 (call_debugger): Bind it instead of Qdebug_on_error.
1884 (maybe_call_debugger): Test Vinhibit_debugger.
1885 (syms_of_eval): Define inhibit-debugger.
1886 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
1887 (syms_of_xdisp): Remove inhibit-debug-on-message.
1889 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
1891 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
1892 If a nonvolatile local variable is written before a _longjmp to
1893 the frame containing the variable, and is read after the _longjmp,
1894 the value read is indeterminate. Some local variables of type
1895 'struct handler' and 'struct catchtag' are used in this way, so
1896 mark each of their slots as volatile if the slot can be set before
1897 _longjmp and read afterwards.
1898 * lisp.h (struct handler): var and chosen_clause are now volatile.
1899 (struct catchtag): val, next, and pdlcount are now volatile.
1901 * bidi.c (bidi_push_it, bidi_pop_it):
1902 * fns.c (copy_hash_table):
1903 * image.c (define_image_type):
1904 * keyboard.c (kbd_buffer_store_event_hold):
1905 * process.c (Fprocess_send_eof):
1906 * xfaces.c (x_create_gc) [HAVE_NS]:
1907 * xgselect.c (xg_select):
1908 Prefer assignment to memcpy when either will do.
1910 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
1911 Use pointer-to-a-pointer to simplify and avoid a NILP check each
1912 time an item is removed. No need to mark this function 'inline';
1913 the compiler knows better than we do.
1915 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
1917 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
1918 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
1919 to change_frame_size (Bug#12388).
1920 (windowDidResize:): Pass YES to updateFrameSize.
1922 * nsterm.h: Add delay parameter to updateFrameSize.
1924 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
1926 Discard killed buffers from deleted window and frame objects.
1927 This reduces an amount of references to killed buffers and
1928 helps GC to reclaim them faster.
1929 * alloc.c (discard_killed_buffers): New function.
1930 (mark_object): Use it for deleted windows and frames.
1931 (mark_object): If symbol's value is set up for a killed buffer
1932 or deleted frame, restore it's global binding.
1933 * data.c (swap_in_global_binding): Add GC notice.
1934 (swap_in_symval_forwarding): Use convenient set_blv_where.
1935 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
1936 * window.h: ... to here.
1938 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
1940 Convenient macro to check whether the buffer is live.
1941 * buffer.h (BUFFER_LIVE_P): New macro.
1942 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
1943 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
1945 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1947 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
1948 composition cases (Bug#12364).
1950 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
1951 overhang of succeeding glyphs overlapping box cursor.
1953 * w32term.c (x_draw_glyph_string): Likewise.
1955 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
1957 Simplify, document, and port floating-point (Bug#12381).
1958 The porting part of this patch fixes bugs on non-IEEE platforms
1959 with frexp, ldexp, logb.
1960 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
1962 * floatfns.c: Simplify discussion of functions that Emacs doesn't
1963 support, by removing commented-out code and briefly listing the
1964 C89 functions excluded. The commented-out stuff was confusing
1965 maintenance, e.g., we thought we needed cbrt but it was commented out.
1966 (logb): Remove decl; no longer needed.
1967 (isfinite): New macro, if not already supplied.
1968 (isnan): Don't replace any existing macro.
1969 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
1970 are present on all C89 platforms.
1971 (Ffrexp): Do not special-case zero, as frexp does the right thing
1973 (Flogb): Do not use logb, as it doesn't have the desired meaning
1974 on hosts that use non-base-2 floating point. Instead, stick with
1975 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
1976 frexp, to avoid getting an unspecified result.
1978 * xdisp.c (Qinhibit_debug_on_message): Now static.
1980 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
1982 * nsterm.m (ns_update_begin): Set clip path to whole view by using
1983 NSBezierPath (Bug#12131).
1985 2012-09-10 Chong Yidong <cyd@gnu.org>
1987 * fns.c (Fdelq, Fdelete): Doc fix.
1989 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
1991 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
1992 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
1994 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
1996 * lisp.h (make_lisp_ptr): New macro to replace XSET.
1997 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
2000 2012-09-09 Eli Zaretskii <eliz@gnu.org>
2002 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
2003 left fringe if the window has a left margin. This avoids leaving
2004 traces of the cursor because its leftmost pixel is not drawn over.
2006 * dispnew.c (update_window_line): When the left margin area of a
2007 screen line is updated, set the redraw_fringe_bitmaps_p flag of
2008 that screen line. (Bug#12277)
2010 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
2012 Assume C89 or later for math functions (Bug#12381).
2013 This simplifies the code, and makes it a bit smaller and faster,
2014 and (most important) makes it easier to clean up signal handling
2015 since we can stop worring about floating-point exceptions in
2016 library code. That was a problem before C89, but the problem
2017 went away many years ago on all practical Emacs targets.
2018 * data.c, image.c, lread.c, print.c:
2019 Don't include <math.h>; no longer needed.
2020 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
2021 might be autoconfigured, as that never happens.
2023 * doprnt.c (DBL_MAX_10_EXP):
2024 * print.c (DBL_DIG):
2025 Remove. C89 or later always defines these.
2026 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
2027 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
2028 (arith_error, domain_error, domain_error2):
2029 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
2030 no longer needed -- we simply return what C returns. All uses removed.
2031 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
2033 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
2034 Remove. All uses expanded, as these macros are no longer used
2035 more than once and are now more trouble than they're worth.
2036 (Ftan): Use tan, not sin / cos.
2037 (Flogb): Assume C89 frexp.
2038 (fmod_float): Assume C89 fmod.
2039 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
2040 (init_floatfns): Remove. All uses removed.
2042 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
2044 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
2045 compositeToPoint for OSX < 10.6 (Bug#12390).
2047 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
2049 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
2050 This produces more-accurate results.
2052 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
2054 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
2055 changes (Bug#12088).
2057 2012-09-08 Chong Yidong <cyd@gnu.org>
2059 * syntax.c (Fstring_to_syntax): Doc fix.
2061 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
2063 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
2064 in the internal border.
2065 (x_set_window_size): Remove static variables and their usage.
2066 (ns_redraw_scroll_bars): Fix NSTRACE arg.
2067 (ns_after_update_window_line, ns_draw_fringe_bitmap):
2068 Remove fringe/internal border adjustment (Bug#11052).
2069 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
2070 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
2071 (ns_fix_rect_ibw): Remove.
2072 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
2073 (ns_dumpglyphs_box_or_relief): Ditto.
2074 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
2076 (ns_dumpglyphs_image): Ditto.
2077 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
2079 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
2080 their usage. Add fringe_extended_p and its use as in other terms.
2081 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
2082 scroll bar was removed.
2083 (updateFrameSize): New function.
2084 (windowDidResize): Move code to updateFrameSize and call it.
2086 * nsterm.h (EmacsView): Add updateFrameSize.
2088 2012-09-07 Chong Yidong <cyd@gnu.org>
2090 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
2092 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
2094 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
2096 More signal-handler cleanup (Bug#12327).
2097 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
2098 Problem introduced when merging patches. Noted by Eli Zaretskii in
2099 <http://bugs.gnu.org/12327#67>.
2100 * floatfns.c: Comment fix.
2101 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
2102 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
2103 and anyway the declaration is harmless even if SIGDANGER is not defined.
2104 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
2105 defined BROKEN_FIONREAD). systty.h formerly did this, but other
2106 source files not surprisingly expected syssignal.h to define, or
2107 not define, SIGIO, and it's cleaner to do it that way, for consistency.
2108 Include <sys/ioctl.h>, for FIONREAD.
2109 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
2110 This eliminates a problem whereby other files mysteriously had
2111 to include "syssignal.h" before including "systty.h" if they
2112 wanted to use "#ifdef SIGIO".
2114 2012-09-07 Eli Zaretskii <eliz@gnu.org>
2116 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
2118 * w32.c (sigemptyset): Empty the set.
2119 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
2121 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
2123 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
2125 * alloc.c (mark_buffer): Revert unsafe marking optimization.
2126 (mark_object): Likewise for frame objects.
2128 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
2130 * syssignal.h (handle_on_main_thread): Always declare,
2131 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
2132 This ports to platforms without HAVE_PTHREAD.
2134 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
2136 Signal-handler cleanup (Bug#12327).
2137 Emacs's signal handlers were written in the old 4.2BSD style with
2138 sigblock and sigmask and so forth, and this led to some
2139 inefficiencies and confusion. Rewrite these to use
2140 pthread_sigmask etc. without copying signal sets around. Also,
2141 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
2142 'signal', and instead use functions that do not attempt to take
2143 over the system name space. This patch causes Emacs's text
2144 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
2145 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
2146 Do not include <signal.h> or "syssignal.h", as these
2147 modules do not use signals.
2148 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
2149 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
2150 Do not include <signal.h>, as "syssignal.h" does that for us now.
2151 * atimer.c (sigmask_atimers): New function.
2152 (block_atimers, unblock_atimers): New functions,
2153 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
2155 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
2156 no longer needed here.
2157 * emacs.c (main): Inspect existing signal handler with sigaction,
2158 so that there's no need to block and unblock SIGHUP.
2159 * sysdep.c (struct save_signal): New member 'action', replacing
2160 old member 'handler'.
2161 (save_signal_handlers, restore_signal_handlers):
2162 Use sigaction instead of 'signal' to save and restore.
2163 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
2164 New function. All users of 'signal' modified to use set_sighandler
2165 if they're writeonly, and to use sys_signal if they're read+write.
2166 (emacs_sigaction_init, forwarded_signal): New functions.
2167 (sys_signal): Remove. All uses replaced by calls to sigaction
2168 and emacs_sigaction_init, or by direct calls to 'signal'.
2169 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
2170 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
2171 all uses replaced by pthread_sigmask etc. calls.
2172 * syssignal.h: Include <signal.h>.
2173 (emacs_sigaction_init, forwarded_signal): New decls.
2174 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
2175 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
2176 (sigmask, sys_sigmask): Remove; no longer needed.
2177 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
2178 (sigblock, sigunblock, sigfree):
2179 (sigsetmask) [!defined sigsetmask]:
2180 Remove. All uses replaced by pthread_sigmask.
2181 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
2182 no longer need to be replaced, and its typical old uses
2183 are now done via emacs_sigaction_init and sigaction.
2184 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
2185 (sys_sigdel): Remove; unused.
2186 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
2188 2012-09-06 Eli Zaretskii <eliz@gnu.org>
2190 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
2191 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
2193 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
2195 Explicitly mark buffer_defaults and buffer_local_symbols.
2196 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
2197 mark_local_symbols here.
2198 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
2199 since special buffers aren't marked here any more.
2200 (allocate_buffer): Chain new buffer with all_buffers here...
2201 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
2203 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
2204 (syms_of_buffer): Remove staticpro of the above.
2205 (init_buffer_once): Set names for buffer_defaults and
2206 buffer_local_symbols.
2208 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
2210 Use bool for booleans in font-related modules.
2211 * font.c (font_intern_prop, font_style_to_value)
2212 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
2213 (generate_otf_features, font_check_otf_features, font_check_otf)
2214 (font_match_p, font_list_entities, font_at):
2215 * fontset.c (fontset_id_valid_p, reorder_font_vector
2216 (fontset_find_font, Fset_fontset_font)
2217 (face_suitable_for_char_p) [0]:
2218 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
2219 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
2220 (m17n_flt_initialized, ftfont_shape_by_flt):
2221 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
2222 * nsfont.m (nsfont_draw):
2223 * w32font.c (w32font_draw):
2224 * w32term.c (x_draw_glyphless_glyph_string_foreground):
2225 Use bool for booleans.
2226 * font.h: Adjust to above API changes.
2227 (struct font, struct font_driver, struct font_driver_list):
2228 Use bool for booleans.
2229 (struct font): Remove useless member encoding_type.
2231 * fontset.c, xftfont.c: Omit unnecessary static decls.
2233 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
2235 * alloc.c (mark_object): Revert window marking code
2236 since it's unsafe for the Fset_window_configuration.
2238 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
2240 Fix race conditions with signal handlers and errno (Bug#12327).
2241 Be more systematic about preserving errno whenever a signal
2242 handler returns, even if it's not in the main thread. Do this by
2243 renaming signal handlers to distinguish between signal delivery
2244 and signal handling. All uses changed.
2245 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
2246 * data.c (deliver_arith_signal): Rename from arith_error.
2247 * dispnew.c (deliver_window_change_signal): Rename from
2248 window_change_signal.
2249 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
2250 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
2251 * keyboard.c (deliver_input_available_signal): Rename from
2252 input_available_signal.
2253 (deliver_user_signal): Rename from handle_user_signal.
2254 (deliver_interrupt_signal): Rename from interrupt_signal.
2255 * process.c (deliver_pipe_signal): Rename from send_process_trap.
2256 (deliver_child_signal): Rename from sigchld_handler.
2257 * atimer.c (handle_alarm_signal):
2258 * data.c (handle_arith_signal):
2259 * dispnew.c (handle_window_change_signal):
2260 * emacs.c (handle_fatal_signal, handle_danger_signal):
2261 * keyboard.c (handle_input_available_signal):
2262 * keyboard.c (handle_user_signal, handle_interrupt_signal):
2263 * process.c (handle_pipe_signal, handle_child_signal):
2264 New functions, with the actual signal-handling code taken from the
2265 original respective signal handlers, sans the sporadic attempts to
2266 preserve errno, since that's now done by handle_on_main_thread.
2267 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
2268 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
2269 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
2271 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
2272 Move initialization of main_thread to sysdep.c's init_signals.
2273 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
2274 our usage, and simplifies the mainline code.
2275 (record_child_status_change): New static function, as a helper
2276 for handle_child_signal, and with most of the old child handler's
2278 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
2279 (handle_child_signal): Use the above.
2280 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
2281 Moved here from emacs.c.
2282 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
2283 code moved here from emacs.c's main function.
2284 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
2285 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
2286 This lets callers save and restore errno properly.
2288 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
2290 Remove redundant or unused things here and there.
2291 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
2292 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
2293 * editfns.c (Fcompare_buffer_substrings): Likewise.
2294 * frame.h (struct terminal, struct font_driver_list):
2295 Remove redundant declarations.
2296 * window.h (Qleft, Qright): Likewise.
2298 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
2300 Do not mark objects from deleted buffers, windows and frames.
2301 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
2302 (mark_object): Likewise for windows and frames.
2304 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
2306 * alloc.c (valid_lisp_object_p): Treat killed buffers,
2307 buffer_defaults and buffer_local_symbols as valid objects.
2308 Return special value to denote them.
2310 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
2312 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
2313 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
2314 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
2315 (file_name_absolute_p, Fsubstitute_in_file_name):
2316 (check_executable, check_writable, Ffile_accessible_directory_p)
2317 (Fset_file_selinux_context, Fdefault_file_modes)
2318 (Finsert_file_contents, choose_write_coding_system)
2319 (Fwrite_region, build_annotations, a_write, e_write)
2321 * filelock.c (boot_time_initialized, get_boot_time)
2322 (get_boot_time_1, lock_file_1, within_one_second):
2323 * floatfns.c (in_float):
2324 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
2325 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
2326 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
2327 * lisp.h (struct Lisp_Hash_Table.cmpfn):
2328 * window.c (compare_window_configurations):
2329 Use bool for booleans.
2330 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
2331 (Fdefault_file_modes): Now mode_t, not int, for modes.
2332 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
2333 (internal_delete_file): Now returns void, not a (boolean) int,
2334 since nobody was looking at the return value.
2335 * lisp.h, window.h: Adjust to above API changes.
2337 * xdisp.c (set_message): Simplify and reindent last change.
2339 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
2341 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
2343 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
2345 * eval.c (call_debugger): Make the function non-static so that we
2346 can call it from set_message.
2348 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
2349 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
2351 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
2353 Give more-useful info on a fatal error (Bug#12328).
2354 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
2355 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
2356 of doing the work ourselves.
2357 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
2358 do most of the work.
2359 (fatal_error_backtrace): New function, taken from the guts
2360 of the old fatal_error_signal, but with a new option to output
2362 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
2363 info about the signal than just its number.
2364 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
2365 * sysdep.c: Include <execinfo.h>
2366 (emacs_backtrace): New function, taken partly from the previous
2367 code of the 'die' function.
2368 (emacs_abort): Call fatal_error_backtrace rather than abort.
2370 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
2372 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
2373 eager (load-time) macro-expansion.
2374 * lisp.mk (lisp): Add macroexp.
2376 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
2378 Simplify redefinition of 'abort' (Bug#12316).
2379 Do not try to redefine the 'abort' function. Instead, redo
2380 the code so that it calls 'emacs_abort' rather than 'abort'.
2381 This removes the need for the NO_ABORT configure-time macro
2382 and makes it easier to change the abort code to do a backtrace.
2383 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
2384 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
2385 Remove; sysdep.c's emacs_abort now takes its place.
2386 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
2387 'abort' changed to use 'emacs_abort'.
2388 * msdos.c (dos_abort) [defined abort]: Remove; not used.
2389 (abort) [!defined abort]: Rename to ...
2390 (emacs_abort): ... new name.
2391 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
2392 the place of the old 'abort' in emacs.c.
2393 * w32.c, w32fns.c (abort): Do not #undef.
2394 * w32.c (emacs_abort): Rename from w32_abort.
2396 2012-09-04 Eli Zaretskii <eliz@gnu.org>
2398 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
2399 offsets[j].dv, since the y axis of the screen coordinates points
2400 down, while the y axis of the font definition coordinates points
2401 up. This fixes display of Arabic diacritics such as KASRA and
2402 KASRATAN. (Bug#11860)
2404 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
2406 Be more systematic about _setjmp vs setjmp.
2407 * alloc.c (test_setjmp, mark_stack):
2408 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
2409 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
2410 (png_load, my_error_exit, jpeg_load):
2411 * process.c (send_process_trap, send_process):
2412 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
2413 The underscored versions are up to 30x faster on some hosts.
2414 Formerly, the code used setjmp+longjmp sometimes and
2415 _setjmp+_longjmp at other times, with no particular reason to
2416 prefer setjmp+longjmp.
2418 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
2420 Fix minor problem found by static checking.
2421 * buffer.c (Fdelete_all_overlays): Return nil.
2423 2012-09-03 Martin Rudalics <rudalics@gmx.at>
2425 * buffer.c (Fdelete_all_overlays): New function.
2427 2012-09-03 Chong Yidong <cyd@gnu.org>
2429 * gtkutil.c: Add extern decl for Qxft.
2431 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>

2445 All callers changed.
2446 * eval.c (interactive_p): Omit always-true boolean argument
2447 EXCLUDE_SUBRS_P. All callers changed.
2448 * dispextern.h, lisp.h: Reflect above API changes.
2449 * firstfile.c (dummy): Use the address of 'main', whose signature
2450 won't change, instead of the address of 'initialize', whose
2451 signature just changed from int to bool.
2452 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
2453 * msdos.c (fatal_error_in_progress): ... from here.
2454 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
2456 (redisplay_internal, unwind_redisplay): Simply clear
2457 REDISPLAYING_P when unwinding, instead of saving its previous,
2458 always-false value and then restoring it.
2460 Clean up some extern decls.
2461 Mostly, this hoists extern decls out of .c files and into .h files.
2462 That way, we're more likely to catch errors if the interfaces change.
2463 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
2464 declare xg_mark_data.
2465 * dispextern.h (x_frame_parm_handlers):
2467 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)

2483 * xfont.c (x_clear_errors):
2484 * xterm.c (x_frame_parm_handlers):
2485 Remove now-redundant extern decls.
2486 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
2487 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
2489 * xfaces.c: Remove unnecessary static decls.
2490 * xterm.c (updating_frame): Remove decl of nonexistent object.
2492 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
2493 when building globals.h, as the objects that are not built on
2494 this host are not needed to compile C files on this host.
2496 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
2498 * gtkutil.h: Remove prototype for x_wm_set_size_hint.

2512 (make_buffer_string, make_buffer_string_both)
2513 (Fsubst_char_in_region, Ftranslate_region_internal, Fformat):
2514 * insdel.c (check_markers, gap_left, adjust_markers_for_insert)

2525 (set_intervals_multibyte_1, set_intervals_multibyte):
2526 * keyboard.c (decode_timer):
2527 Use bool for boolean.
2528 * intervals.h, lisp.h, systime.h: Reflect above API changes.
2529 * editfns.c (struct info): Use 1-bit unsigned bitfields for booleans.
2531 2012-09-02 Chong Yidong <cyd@gnu.org>
2533 * keymap.c (push_key_description): Print M-TAB as C-M-i
2536 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
2538 * makefile.w32-in (CCL_H, W32FONT_H): New macros.

2544 ($(BLD)/w32font.$(O), $(BLD)/w32uniscribe.$(O)): Update dependencies.
2546 2012-09-01 Eli Zaretskii <eliz@gnu.org>
2548 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
2549 more than one grapheme cluster passed to the shaper: compute the
2550 offset adjustment values separately for each cluster. (Bug#11860)
2552 * image.c: Restore mistakenly removed inclusion of w32.h. Without
2553 it, GCC doesn't see prototypes of w32_delayed_load, and complains
2554 about implicit conversions from integer to pointer.
2556 2012-09-01 Daniel Colascione <dancol@dancol.org>
2558 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
2559 system used too early.
2561 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
2563 Better seed support for (random).

2592 * process.c: Include TERM_HEADER instead of listing all possible
2593 window-system headers.
2595 * nsterm.h: Remove declarations now in frame.h.
2596 Define FRAME_X_SCREEN, FRAME_X_VISUAL.
2598 * menu.c: Include TERM_HEADER instead of listing all possible
2599 window-system headers.
2601 * keyboard.h: Declare ignore_mouse_drag_p whenever we have a
2604 * keyboard.c: Include TERM_HEADER instead of listing all possible
2605 window-system headers.
2607 * image.c: Include TERM_HEADER instead of listing all possible
2608 window-system headers. Declare Vlibrary_cache when compiling for
2611 * gtkutil.h (xg_list_node_): Include xterm.h to pick up needed
2612 window system declarations.
2614 * frame.h: Move common functions here: set_frame_menubar,
2615 x_set_window_size, x_sync, x_get_focus_frame,
2616 x_set_mouse_position, x_set_mouse_pixel_position,
2617 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

2641 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
2643 Remove mark_ttys function and fix tty_display_info initialization.
2644 * lisp.h (mark_ttys): Remove prototype.
2645 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
2646 to mark_ttys because all possible values of 'top_frame' slot are
2647 the frames which are reachable from Vframe_list.
2648 * term.c (mark_ttys): Remove.
2649 (init_tty): Safely initialize 'top_frame' slot with Qnil.
2651 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
2653 Change struct frame bitfields from unsigned char to unsigned.
2654 * frame.h (struct frame): Change type of 'display_preempted',

2656 'auto_raise', 'auto_lower', 'no_split', 'explicit_name',
2657 'window_sizes_changed', 'mouse_moved' and 'pointer_invisible'
2658 bitfields from unsigned char to unsigned.

2671 2012-08-30 Paul Eggert <eggert@cs.ucla.edu>
2673 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
2674 for GCC 4.7.1 x86-64.
2676 2012-08-30 Glenn Morris <rgm@gnu.org>
2678 * lread.c (init_lread): For out-of-tree builds, only add the
2679 source directory's site-lisp dir to the load-path if it exists,
2680 consistent with in-tree builds. (Bug#12302)
2682 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>
2684 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize

2686 (windowShouldClose:): Set window_closed.
2687 (dealloc): New member, free button_values.
2688 (process_dialog:): Make member function. Remove window argument,
2689 replace window with self. Count buttons and allocate and store values
2691 (addButton:value:row:): value is int with the name tag. Call setTag
2692 with tag. Remove return self, declare return value as void.
2693 (addString:row:): Remove return self, declare return value as void.
2694 (addSplit): Remove return self, declare return value as void.
2695 (clicked:): Remove return self, declare return value as void.
2696 Set dialog_return to button_values[seltag]. Code formatting change.
2697 (initFromContents:isQuestion:): Adjust call to process_dialog.
2698 Code formatting change.
2699 (timeout_handler:): Set timer_fired to YES.
2700 (runDialogAt:): Set timer_fired to NO.
2701 Handle click on close button as quit.
2703 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
2704 Add window_closed and button_values. Add void as return value for
2705 add(Button|String|Split). addButton takes int instead of Lisp_Object.
2706 Add process_dialog as new member.
2708 2012-08-28 Eli Zaretskii <eliz@gnu.org>
2710 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it
2711 is not one of the heaps we manage. (Bug#12242)
2713 2012-08-28 Glenn Morris <rgm@gnu.org>
2715 * eval.c (Fcalled_interactively_p): Doc fix. (Bug#11747)
2717 2012-08-28 Martin Rudalics <rudalics@gmx.at>
2719 * window.c (Fset_window_configuration): Remove handling of

2742 Fix usage of set_buffer_internal.
2743 * buffer.h (set_buffer_internal): Make it BUFFER_INLINE.

2773 (clear_glyph_matrix_rows): Rename from enable_glyph_matrix_rows,
2774 and remove last int (actually boolean) argument, which was always 0.
2775 All callers changed.
2776 * dispextern.h, frame.h, lisp.h: Reflect above API changes.
2777 * dispextern.h (struct composition_it): Use bool for boolean.

2779 (struct bidi_it): Use unsigned:1, not int, for boolean prev_was_pdf.
2780 * dired.c (file_name_completion):

2793 Initialize dialog_return.
2794 (windowShouldClose:): Use stop instead of stopModalWithCode.
2795 (clicked:): Ditto, and also set dialog_return (Bug#12258).
2796 (timeout_handler:): Use stop instead of abortModal. Send a dummy

2845 * coding.c: Remove unnecessary static function decls.
2846 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
2847 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
2848 not a boolean 'int', since callers never look at the return value.

2864 2012-08-27 Martin Rudalics <rudalics@gmx.at>
2866 * window.c (Fset_window_configuration): Record any window's old

2868 buffer doesn't appear in the selected window, go to its old
2871 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
2873 Special MEM_TYPE_SPARE to denote reserved memory.
2874 * alloc.c (enum mem_type): New memory type.
2875 (refill_memory_reserve): Use new type for spare memory.
2876 This prevents live_cons_p and live_string_p from incorrect
2877 detection of uninitialized objects from spare memory as live.
2879 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>

2905 (map_sub_char_table):
2906 Use bool for boolean.
2907 * character.c (str_to_unibyte): Omit last boolean argument; it was
2908 always 0. All callers changed.
2909 * character.h, charset.h: Adjust to match previous changes.
2910 * character.h (char_printable_p): Remove decl of nonexistent function.
2911 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
2912 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
2913 are all boolean, so make them single-bit bitfields.
2915 * lisp.h (ASET): Remove attempt to detect side effects.
2916 It was meant to be temporary and it often doesn't work,
2917 because when IDX has side effects the behavior of IDX==IDX
2918 is undefined. See Stefan Monnier in
2919 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
2921 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
2923 * lisp.h (functionp): New function (extracted from Ffunctionp).
2924 (FUNCTIONP): Use it.
2925 * eval.c (Ffunctionp): Use it.
2927 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
2929 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
2930 as that's faster and simpler than static storage. Don't bother
2931 with the g_main_context_query overhead if g_main_context_pending
2932 says no events are pending.
2933 (gfds, gfds_size): Remove these static vars.
2934 (xgselect_initialize): Remove; no longer needed.
2935 All uses and decls removed.
2937 * emacs.c (fatal_error_signal_hook): Remove.
2938 All uses removed. This leftover from old code was always 0.
2940 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
2941 * casefiddle.c (casify_object, casify_region):
2942 * casetab.c (set_case_table):
2943 * category.c, category.h (word_boundary_p):
2944 * category.h (CHAR_HAS_CATEGORY):
2945 Use bool for booleans, instead of int.
2947 2012-08-25 Eli Zaretskii <eliz@gnu.org>
2949 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
2951 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
2953 On assertion failure, print backtrace if available.
2954 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
2955 (die) [ENABLE_CHECKING]: Print a backtrace if available.
2956 * Makefile.in (LIB_EXECINFO): New macro.
2959 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
2960 * bytecode.c (exec_byte_code):
2961 * callint.c (check_mark, Fcall_interactively):
2962 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
2963 (getenv_internal, sync_process_alive, call_process_exited):
2964 * lisp.h (USE_SAFE_ALLOCA):
2965 Use bool for booleans, instead of int.
2966 * lisp.h, process.h: Adjust prototypes to match above changes.
2967 * callint.c (Fcall_interactively): Don't assume the mark's
2968 offset fits in 'int'.
2970 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
2972 * buffer.c, buffer.h: Use bool for boolean.
2973 * buffer.c (reset_buffer_local_variables)

2979 (mmap_enlarge, mmap_set_vars):
2980 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
2981 Use bool for booleans, instead of int.
2982 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
2983 since the 1-or-0 return value is always ignored anyway.
2984 (mmap_initialized_p):
2985 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
2986 * buffer.h, lisp.h: Adjust prototypes to match above changes.
2988 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
2990 * bidi.c: Use bool for boolean.
2991 This is a bit more readable, and makes the text segment of bidi.o
2992 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
2993 Presumably it's faster too.
2994 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
2996 (bidi_cache_find_level_change, bidi_cache_iterator_state)
2997 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)

2999 (bidi_explicit_dir_char, bidi_level_of_next_char)
3000 (bidi_find_other_level_edge, bidi_move_to_visually_next):
3001 Use bool for booleans, instead of int.
3002 * dispextern.h (bidi_init_it, bidi_paragraph_init)
3003 (bidi_unshelve_cache): Adjust decls to match code.
3005 2012-08-23 Martin Rudalics <rudalics@gmx.at>
3007 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
3010 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
3012 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
3013 * atimer.h: Include <stdbool.h>.
3015 2012-08-22 Dan Nicolaescu <dann@gnu.org>
3017 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
3018 compile time tests instead of run time tests on systems that do
3020 (FRAME_MAC_P): Remove leftover from deleted code.
3021 * frame.c (syms_of_frame): Remove leftover from deleted code.
3023 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
3025 * nsterm.m (insertText:): Don't clear modifiers if code is space.
3027 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
3029 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
3030 Otherwise, the compiler complains about (A?B:C) where B is void
3031 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
3032 (fontset_add): Return void, for FONTSET_ADD.
3034 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
3036 * alloc.c: Use bool for booleans.
3037 (gc_in_progress, abort_on_gc)
3038 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
3039 (dont_register_blocks) [GC_MALLOC_CHECK]:
3040 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
3041 (check_string_bytes, make_specified_string, memory_full)
3042 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
3043 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
3044 (mark_stack, valid_pointer_p, make_pure_string)
3045 (Fgarbage_collect, survives_gc_p, gc_sweep):
3046 Use bool for booleans, instead of int.
3047 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
3048 Remove unused local.
3049 * alloc.c (PURE_POINTER_P):
3050 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
3051 * editfns.c (Fformat):
3052 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
3054 * fns.c (sweep_weak_table):
3055 * lisp.h (suppress_checking, push_message, survives_gc_p)
3056 (make_pure_string, gc_in_progress, abort_on_gc):
3057 * lread.c (readchar, read1):
3058 * print.c (Fprin1_to_string):
3059 * xdisp.c (push_message):
3060 Use bool for booleans affected directly or indirectly by
3063 Make recently-introduced setters macros.
3064 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
3065 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
3066 (set_fontset_default, set_fontset_fallback): Rename from their
3067 upper-case counterparts, and make them functions rather than macros.
3068 This is more consistent with the other recently-introduced setters.
3069 These don't need to be inline, since they're local.
3071 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
3073 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
3074 the loop (Bug#12247).
3076 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
3078 * lisp.h (vcopy): Use memcpy rather than our own loop.
3079 This fixes a performance regression introduced by the recent
3080 addition of vcopy. This means 'vcopy' will need to be modified
3081 for a copying collector, but that's OK. Also, tighten the
3082 checking in the assertion.
3084 2012-08-21 Eli Zaretskii <eliz@gnu.org>
3086 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
3087 components for RTL text (Bug#11860). Adjust X-OFFSET of each
3088 non-base glyph for the width of the base character, according to
3089 what x_draw_composite_glyph_string_foreground expects.
3090 Generate WADJUST value according to composition_gstring_width's
3091 expectations, to produce correct width of the composed character.
3092 Reverse the sign of the DU offset produced by ScriptPlace.
3094 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
3096 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
3098 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
3100 Avoid direct writes to contents member of struct Lisp_Vector.
3101 * lisp.h (vcopy): New function to copy data into vector.
3102 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
3103 * fns.c (Ffillarray): Use ASET.
3104 * keyboard.c (timer_check_2): Use AREF and ASET.
3105 (append_tool_bar_item, Frecent_keys): Use vcopy.
3106 * lread.c (read_vector): Use ASET.
3107 * msdos.c (Frecent_doskeys): Use vcopy.
3108 * xface.c (Finternal_copy_lisp_face): Use vcopy.
3109 (Finternal_merge_in_global_face): Use ASET and vcopy.
3110 * xfont.c (xfont_list_pattern): Likewise.
3112 2012-08-21 Martin Rudalics <rudalics@gmx.at>

3115 the position of its buffer's point.
3116 (Fset_window_point): For the selected window always go in its
3117 buffer to the specified position.
3119 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
3121 Setter macros for fontsets.
3122 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
3123 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
3124 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
3127 2012-08-20 Glenn Morris <rgm@gnu.org>
3129 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
3130 Don't assume that `ln -f' works.
3132 2012-08-20 Eli Zaretskii <eliz@gnu.org>
3134 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
3135 and later about non-assignments with no effect. See discussion at
3136 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
3139 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
3141 Inline setter functions for Lisp_Objects slots of struct specbinding.
3142 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
3145 2012-08-20 Martin Rudalics <rudalics@gmx.at>
3147 * window.c (select_window): Always make selected window's buffer
3150 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
3152 Use AREF and ASET for docstrings of category tables.
3153 * category.h (CATEGORY_DOCSTRING): Use AREF.
3154 (SET_CATEGORY_DOCSTRING): Use ASET.
3155 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
3157 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
3159 Inline setter functions for hash table members.
3160 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
3161 (set_hash_hash, set_hash_index): Rename with _slot suffix.
3162 (set_hash_key_and_value, set_hash_index, set_hash_next)
3163 (set_hash_hash): New functions.
3164 * charset.c, fns.c: Adjust users.
3166 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
3168 Inline getter and setter functions for per-buffer values.
3169 * buffer.h (per_buffer_default, set_per_buffer_default)
3170 (per_buffer_value, set_per_buffer_value): New functions.

3174 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
3176 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
3178 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
3180 Rely on <config.h> + <unistd.h> to declare 'environ',
3181 as gnulib does this if the system doesn't.
3182 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
3183 Remove declaration. MS-Windows declares it on stdlib.h which is

3186 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.

4051 2012-08-04 Eli Zaretskii <eliz@gnu.org>
4053 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
4054 * w32.c (init_environment): Change the default values of many
4055 environment variables in dflt_envvars[] to NULL, to avoid pushing
4056 them into environment when they were not already defined.
4057 Remove the code that deletes site-lisp subdirectories from the default
4058 value of EMACSLOADPATH, as it is no longer needed.
4059 (check_windows_init_file): Now external, not static.
4060 Use Vload_path as is, without adding anything, as this function is now
4061 called when Vload_path is already set up.
4063 * w32.h (check_windows_init_file): Add prototype.
4065 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build
4066 directory, ignore the /*/i386/ tail in Vinvocation_directory, for
4067 compatibility with Posix platforms.
4068 (main): Move the call to check_windows_init_file to here from
4070 (decode_env_path) [WINDOWSNT]: Expand the %emacs_dir%/ prefix, if
4071 any, in the DEFALT argument into the root of the Emacs build or
4072 installation tree, as appropriate.
4074 * callproc.c (init_callproc_1): Call decode_env_path instead of
4075 doing its equivalent by hand.
4076 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
4077 the code that sets Vexec_path run on MS-Windows.
4079 * lread.c (init_lread): Add comments to #ifdef's.
4081 * msdos.c (dos_set_window_size, IT_update_begin)
4082 (IT_frame_up_to_date, IT_set_frame_parameters): Use FVAR and WVAR
4083 instead of direct references.
4085 2012-08-04 Paul Eggert <eggert@cs.ucla.edu>
4087 Export DEFAULT_REHASH_* to GDB.
4088 * lisp.h (DEFAULT_REHASH_THRESHOLD, DEFAULT_REHASH_SIZE):
4089 Now constants, not macros.
4091 2012-08-03 Paul Eggert <eggert@cs.ucla.edu>
4093 Remove unnecessary casts involving pointers.
4094 These casts are no longer needed now that we assume C89 or later,
4095 since they involve casting to or from void *.
4096 * alloc.c (make_pure_string, make_pure_c_string, pure_cons)
4097 (make_pure_float, make_pure_vector):
4098 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP):

4103 * xdisp.c (x_produce_glyphs):
4104 * xfaces.c (compare_fonts_by_sort_order):
4105 * xfns.c (x_real_positions, select_visual):
4106 * xselect.c (x_stop_queuing_selection_requests)
4107 (x_get_window_property, x_get_window_property_as_lisp_data):
4108 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
4109 Remove unnecessary pointer casts.
4110 * alloc.c (record_xmalloc): New function.
4111 * lisp.h (record_xmalloc): New decl.
4112 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
4113 more like a function. This is because the pointer cast is not
4114 needed. All uses changed.
4115 * print.c (print_string, print_error_message): Avoid length recalc.
4117 Improve fix for macroexp crash with debugging (Bug#12118).
4118 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
4119 ARRAY_MARK_FLAG when checking subscripts, because ASET is
4120 not supposed to be invoked from the garbage collector.
4121 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
4122 (gc_aset): New function, which is like ASET but can be
4123 used in the garbage collector.
4124 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)
4125 (set_hash_index): Use it instead of ASET.

4134 <g_b_init_create_symbolic_link>: New static flags.
4135 (globals_of_w32): Initialize them to zero.
4136 (GetSecurityInfo_Proc, CreateSymbolicLink_Proc): New typedefs.
4137 (map_w32_filename): Improve commentary. Simplify switch.
4138 (SYMBOLIC_LINK_FLAG_DIRECTORY): Define if not defined in system
4139 headers (most versions of MinGW w32api don't).
4140 (get_security_info, create_symbolic_link)
4141 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
4143 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
4144 in the argument file name.
4145 (sys_access): Call unc_volume_file_attributes only if
4146 GetFileAttributes fails with network-related error codes.
4147 (sys_rename): Diagnose renaming of a symlink when the user doesn't
4148 have the required privileges.
4149 (get_file_security_desc_by_name): Rename from
4150 get_file_security_desc.
4151 (stat_worker): New function, with most of the guts of 'stat', and
4152 with addition of handling of symlinks and support for 'lstat'.
4153 If possible, get file's attributes and security information by
4154 handle, not by name. Produce S_IFLNK bit for symlinks, when
4155 called from 'lstat'.
4156 (stat, lstat): New functions, call 'stat_worker'.
4157 (symlink, readlink, careadlinkat): Rewritten to create and resolve
4158 symlinks when the underlying filesystem supports them.
4160 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
4162 Fix macroexp crash on Windows with debugging (Bug#12118).
4163 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
4164 checking subscripts; problem introduced with the recent
4165 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
4166 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
4167 since it's used in non-static inline functions now.
4169 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
4170 Don't assume buffer size fits in 'int'. Remove unused local.
4172 Use C99-style 'extern inline' if available.
4173 * buffer.h (BUFFER_INLINE):
4174 * category.h (CATEGORY_INLINE):
4175 * character.h (CHARACTER_INLINE):
4176 * charset.h (CHARSET_INLINE):

4182 * buffer.h, category.h, character.h, charset.h, composite.h:
4183 * dispextern.h, lisp.h, systime.h:
4184 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
4185 * alloc.c (LISP_INLINE):
4186 * buffer.c (BUFFER_INLINE):
4187 * category.c (CATEGORY_INLINE):
4188 * character.c (CHARACTER_INLINE):
4189 * charset.c (CHARSET_INLINE):
4190 * composite.c (COMPOSITE_INLINE):
4191 * dispnew.c (DISPEXTERN_INLINE):
4192 * sysdep.c (SYSTIME_INLINE):
4193 Define to EXTERN_INLINE, so that the corresponding functions
4194 are compiled into code.
4195 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
4196 (INLINE_HEADER_END): New macros.
4197 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

4217 hard-coding the path separator.
4219 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
4221 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
4222 This how ASET and AREF are supposed to work, and makes
4223 it easier to think about future improvements. See
4224 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
4225 * charset.h (set_charset_attr): New function.
4226 All lvalue-style uses of CHARSET_DECODER etc. changed to use it.
4227 * lisp.h (ASET): Rewrite so as not to use AREF in an lvalue style.

4605 w32_console_unicode_input.
4606 (fill_queue): Call w32_read_console_input instead of ReadConsoleInput.
4607 (w32_kbd_patch_key, key_event): Use the codepage returned by
4608 GetConsoleCP, rather than the ANSI codepage returned by GetLocaleInfo.

4640 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
4641 enumeration constants, as PURE and HEAP are too general, and clash
4642 with other headers and sources, such as gmalloc.c and the
4643 MS-Windows system headers. All users changed.
4645 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
4647 Revert last save_excursion_save and save_excursion_restore changes.
4648 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

4661 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
4662 arms of an 'if', not using conditional expressions; otherwise GDB
4663 complains about the types in the unevaluated arm when the argument
4664 is an integer literal.
4665 (xgetint): Simplify expression.
4666 * alloc.c (gdb_make_enums_visible): New constant. This ports to
4667 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
4668 Zaretskii in <http://bugs.gnu.org/12036#13>.
4669 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
4670 needed now that we have gdb_make_enums_visible.
4671 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
4672 (enum enum_USE_LSB_TAG):
4673 New enum types, packaging up enums that need to be exported to GDB.

4715 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
4716 emacs.c, as this is a more-suitable home. Had this been done earlier
4717 the fix for 12036 would have avoided some of the problems noted in
4718 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
4719 would have been more obvious.
4720 * emacs.c: Do not include <verify.h>; no longer needed.
4721 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
4722 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
4723 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):

4729 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
4730 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
4731 not be usable in #if. This simplifies things.
4733 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
4735 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.

4740 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
4741 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
4742 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
4743 Adjust to changes in lisp.h and emacs.c, by using
4744 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
4745 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
4746 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
4747 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
4748 instead of gdb_valbits.
4749 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
4750 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
4751 instead of gdb_array_mark_flag.
4752 (xboolvector): Get size from $->size, not $->header.size.
4753 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
4754 (xreload, hook-run, hookpost-run): Remove.
4755 * emacs.c: Include <verify.h>.
4756 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
4757 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
4759 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
4760 (gdb_USE_LSB_TAG): New enum constants.
4761 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
4762 Also define these as enum constants, so they're visible to GDB.
4763 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
4764 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
4765 as constants, so they're visible to GDB.

4768 Now enum constants, not macros, so they're visible to GDB.
4769 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
4770 more convenient now. All uses changed.
4771 (VALMASK) [USE_LSB_TAG]: Also define in this case.
4772 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
4774 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

4781 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
4782 add argument, tune behavior, and adjust all callers.
4784 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
4786 Use typedef for EMACS_INT, EMACS_UINT.
4787 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
4788 than macros. This simplifies debugging in the usual case, since
4789 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
4790 and it allows expressions involving EMACS_INT casts.
4791 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
4793 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

4803 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
4805 Adjust buffer text indirection counters at the end of Fkill_buffer.
4806 * buffer.c (Fkill_buffer): Adjust indirection counters when the
4807 buffer is definitely dead. This should really fix an issue reported
4808 by Christoph Scholtes again. (Bug#12007).
4809 (init_buffer_once): Initialize indirection counters of
4810 buffer_defaults and buffer_local_symbols (for sanity and safety).
4812 2012-07-24 Eli Zaretskii <eliz@gnu.org>
4814 * xdisp.c (init_iterator): Don't compute dimensions of truncation
4815 and continuation glyphs on tooltip frames, leave them at zero.

4843 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
4845 Swap buffer text indirection counters in Fbuffer_swap_text.
4846 * buffer.c (Fbuffer_swap_text): Swap indirections too.
4847 This avoids crash reported by Christoph Scholtes at
4848 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
4850 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
4852 * nsmenu.m (Popdown_data): New struct.
4853 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
4855 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
4856 (initWithContentRect): Make imgView and contentView non-static
4857 and autorelease them. Also autorelease img and matrix (Bug#12005).
4858 (dealloc): Remove (Bug#12005).
4860 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
4862 Adjust consing_since_gc when objects are explicitly freed.

4875 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
4877 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
4878 as it's limited by the amount of memory, not by INT_MAX.
4880 2012-07-21 Eli Zaretskii <eliz@gnu.org>
4882 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
4883 in special-event-map. See the discussion at

5606 * s/aix4-2.h (unix): Remove; no longer needed.
5608 EMACS_TIME simplification (Bug#11875).
5609 This replaces macros (which typically do not work in GDB)
5610 with functions, typedefs and enums, making the code easier to debug.
5611 The functional style also makes code easier to read and maintain.
5612 * systime.h: Include <sys/time.h> on all hosts, not just if
5613 WINDOWSNT, since 'struct timeval' is needed in general.

5626 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
5627 not functions. All uses rewritten to use the following, respectively:
5628 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
5629 (add_emacs_time, sub_emacs_time): New functions.
5630 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.

5653 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
5654 Prefer snprintf to strncpy.
5655 * nsterm.m (ns_term_init):
5656 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
5657 * nsterm.m (ns_term_init):
5658 Avoid the need for strncpy, by using build_string or
5659 make_unibyte_string directly. Use dtoastr, not snprintf.
5660 * process.c (Fmake_network_process): Diagnose service names that
5661 are too long, rather than silently truncating them or creating
5662 non-null-terminated names.
5663 (Fnetwork_interface_info): Likewise, for interface names.
5664 * sysdep.c (system_process_attributes) [GNU_LINUX]:
5665 Prefer sprintf to strncat.

5672 Clarify fallback case.
5674 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>

5679 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
5680 where argument type is known to be a Lisp_Cons.

5696 the function is called with compile-time constant argument.
5697 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
5698 argument, adjust users accordingly. Use build_pure_c_string where

5735 O_RDONLY already includes it).
5737 Stop ns builds setting the EMACSLOADPATH environment variable.
5738 * nsterm.m (ns_load_path): Rename from ns_init_paths.
5739 Now it does not set EMACSLOADPATH, just returns the load-path string.
5740 * nsterm.h: Update accordingly.
5741 * lread.c [HAVE_NS]: Include nsterm.h.
5742 (init_lread) [HAVE_NS]: Use ns_load_path.

5752 (ns_init_paths): Do not set EMACSPATH.

5812 Move marker debugging code under MARKER_DEBUG.
5813 * marker.c (MARKER_DEBUG): Move marker debugging code under
5814 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
5815 for bootstrap with --enable-checking (~3x slowdown reported
5816 by Juanma Barranquero <lekktu@gmail.com>).

5822 See <http://bugs.gnu.org/11825#29>.
5824 2012-07-08 Eli Zaretskii <eliz@gnu.org>
5826 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
5827 has no font, use the frame's font. (Bug#11813)
5828 (display_line): Add commentary about displaying truncation glyphs
5830 (produce_special_glyphs): Move here from term.c.
5832 * term.c (produce_special_glyphs): Move to xdisp.c.
5834 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
5837 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
5839 * xdisp.c (display_line): Avoid warning about implicit declaration
5842 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
5844 * lisp.h: Remove empty conditional.
5846 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
5848 * lread.c (load_path_check): Now static.
5850 Fix some minor --with-ns problems found by static checking.
5851 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
5852 (x_set_font) [!HAVE_X_WINDOWS]:
5853 * image.c (xpm_load_image) [HAVE_NS]:
5854 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
5855 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
5856 Remove unused local.
5857 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
5858 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
5859 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
5860 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
5861 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
5862 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
5863 Fix pointer signedness problem.
5864 * xfaces.c (FRAME_X_FONT_TABLE):
5865 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
5867 2012-07-07 Glenn Morris <rgm@gnu.org>
5869 * lread.c (load_path_check): New function, split from init_lread.
5870 (init_lread): Reorganize. Motivation:
5871 If EMACSLOADPATH is set, check/warn about that rather than the
5872 defaults, which we are not going to use. Hence we can remove
5873 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
5874 Don't warn if site-lisp directories are missing.
5875 If not installed, start from a blank load-path, since
5876 PATH_LOADSEARCH refers to the eventual installation directories.
5878 2012-07-07 Eli Zaretskii <eliz@gnu.org>
5880 Support truncation and continuation glyphs on GUI frames, when
5881 fringes are disabled. (Bug#11832)
5882 * xdisp.c (init_iterator): Get dimensions of truncation and
5883 continuation glyphs even if on GUI frames.
5884 Adjust it->last_visible_x on GUI frames when the left or right fringes,
5885 or both, are absent.
5886 (start_display, move_it_in_display_line_to): Handle the case of a
5887 GUI frame without a fringe to display continuation or truncation
5889 (insert_left_trunc_glyphs): Support GUI frames: make sure
5890 truncation glyphs overwrite enough glyphs from the current line to
5891 have sufficient space in pixels.
5892 (display_line): Support truncation and continuation glyphs on GUI
5893 frames. If some spare pixels are left on the line after inserting
5894 the truncation glyphs, fill that space with a stretch glyph of a
5895 suitably computed width.
5897 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
5898 produce_glyphs, to support GUI sessions.
5900 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
5902 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
5904 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
5906 Do not require float-time's arg to fit in time_t (Bug#11825).
5907 This works better on hosts where time_t is unsigned, and where
5908 float-time is applied to the (negative) difference between two times.
5909 * editfns.c (decode_time_components): Last arg is now double *,
5910 not int *, and means to store all the result as a double, without
5911 worrying about whether the seconds part fits in time_t.
5912 All callers changed.
5913 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
5914 All callers changed.
5915 (Ffloat_time): Do not fail merely because the specified time falls
5916 outside of time_t range.
5918 2012-07-07 Glenn Morris <rgm@gnu.org>
5920 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
5921 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
5922 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
5924 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
5926 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
5927 Update dependencies.
5929 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
5931 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
5933 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
5934 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
5935 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
5936 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
5937 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
5938 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
5940 * xfont.c (compare_font_names): Redo to omit the need for casts.
5942 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
5944 * xfns.c (Fx_change_window_property): Doc fix.
5945 * w32fns.c (Fx_change_window_property): Doc fix.
5947 * w32fns.c (Fx_window_property): Accept the same arguments as the
5948 X Windows version. Doc fix.
5949 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
5951 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
5952 Eli Zaretskii <eliz@gnu.org>
5954 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
5955 Windows-specific code from nt/config.nt moved here.
5956 Obsolete settings removed.
5958 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
5960 * process.c: Avoid unnecessary calls to gettime.
5961 (wait_reading_process_output): Don't get the time of day
5962 when gobbling data immediately and not waiting, as there's no need
5963 for it in that case. This removes a FIXME.
5965 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
5967 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
5968 is defined (Bug#11768).
5970 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
5972 Fix marker debugging code.
5973 * marker.c (byte_char_debug_check): Do not perform the check
5974 if buffer is not multibyte.
5975 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
5976 Call byte_char_debug_check with correct arguments.
5978 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
5980 Compile marker debugging code only if ENABLE_CHECKING is defined.
5981 * marker.c (byte_char_debug_check, count_markers):
5982 Use only if ENABLE_CHECKING is defined.
5983 (byte_debug_flag): Remove.
5984 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
5985 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
5987 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
5989 Avoid code repetition in marker-related functions.
5990 * marker.c (attach_marker): New function.
5991 (Fset_marker, set_marker_restricted, set_marker_both)
5992 (set_marker_restricted_both): Use it.
5993 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
5994 Consistently rename charno to charpos.
5995 (marker_position): Add eassert.
5996 (marker_byte_position): Convert to eassert.
5998 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6000 Simplify list operations in unchain_overlay and unchain_marker.
6001 * buffer.c (unchain_overlay): Simplify. Add comment.
6002 * marker.c (unchain_marker): Simplify. Fix comments.
6004 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6006 Introduce fast path for the widely used marker operation.
6007 * alloc.c (build_marker): New function.
6008 * lisp.h (build_marker): New prototype.
6009 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
6010 * composite.c (autocmp_chars): Likewise.
6011 * editfns.c (buildmark): Remove.
6012 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
6013 (save_restriction_save): Use build_marker.
6014 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
6015 * window.c (save_window_save): Likewise.
6017 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6019 Do not use Fdelete_overlay in delete_all_overlays
6020 to avoid redundant calls to unchain_overlay.
6021 * buffer.c (drop_overlay): New function.
6022 (delete_all_overlays, Fdelete_overlay): Use it.
6023 * minibuf.c (get_minibuffer): Fix comment.
6025 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
6027 Port to OpenBSD 5.1 amd64.
6028 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
6029 This is needed for OpenBSD, and should be harmless on all BSD systems.
6030 Also, include <sys/sysctl.h>, as it should be available on all
6031 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
6032 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
6033 use p_pid member, not kp_proc.pid.
6035 2012-07-06 Glenn Morris <rgm@gnu.org>
6037 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
6039 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
6041 More xmalloc and related cleanup.
6042 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
6043 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:
6044 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, fns.c:

6046 * gtkutil.c, image.c, keyboard.c, keymap.c, lread.c, macros.c, menu.c:
6047 * nsfns.m, nsfont.m, nsmenu.m, nsterm.m, print.c, process.c, ralloc.c:
6048 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:
6049 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
6050 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
6052 Omit needless casts involving void * pointers and allocation.
6053 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
6054 as the former is more robust if P's type is changed.
6055 Prefer xzalloc to xmalloc + memset 0.
6056 Simplify malloc-or-realloc to realloc.
6057 Don't worry about xmalloc returning a null pointer.
6058 Prefer xstrdup to xmalloc + strcpy.
6059 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
6061 * keyboard.c (apply_modifiers_uncached): Prefer local array to
6062 alloca of a constant.
6064 2012-07-05 Eli Zaretskii <eliz@gnu.org>
6066 * xdisp.c (display_line): Fix horizontal pixel coordinates when
6067 hscroll is larger than the line width. Fixes long and futile
6068 looping inside extend_face_to_end_of_line (on a TTY) producing
6069 glyphs that are not needed and thrown away.
6071 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
6073 * marker.c (set_marker_restricted_both): Simplify by using
6076 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
6078 * editfns.c (region_limit): Simplify by using clip_to_bounds.
6080 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
6082 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
6083 not defined (Bug#11768).
6084 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
6085 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
6086 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
6087 followed by gtk_box_set_homogeneous (Bug#11768).
6088 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
6089 (update_theme_scrollbar_width, xg_create_scroll_bar):
6090 Use gtk_scrollbar_new (Bug#11768).
6091 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
6092 (is_box_type): New function (Bug#11768).
6093 (xg_tool_item_stale_p): Call is_box_type.
6094 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
6095 with default display (Bug#11768).
6097 2012-07-05 Eli Zaretskii <eliz@gnu.org>
6099 * xdisp.c (window_hscroll_limited): New function.
6100 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
6101 coordinates when window's hscroll is set to insanely large
6104 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
6106 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
6107 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
6109 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
6112 * lisp.h (xzalloc): New prototype. Omit needless casts.
6113 * alloc.c (xzalloc): New function. Omit needless casts.
6114 * charset.c: Omit needless casts. Convert all calls to
6115 xmalloc with following memset to xzalloc.

6165 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
6167 * fileio.c (time_error_value): Check the right error number.
6168 Problem reported by Troels Nielsen in
6169 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
6171 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
6173 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
6174 This should be fixed in a better way; see Eli Zaretskii in
6175 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
6176 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
6178 * fileio.c (time_error_value): Rename from special_mtime.
6179 The old name's problems were noted by Eli Zaretskii in
6180 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
6182 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
6183 This variable's comment says Emacs needs at least one GDB-visible
6184 symbol of type enum pvec_type, to work around GDB problems.
6185 The symbol's value doesn't matter.
6187 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
6188 that causes compilation to fail on pre-C99 compilers.
6190 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
6192 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
6193 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
6195 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
6197 * buffer.c (init_buffer_once): Fix initialization of
6198 headers for buffer_defaults and buffer_local_symbols.
6199 Reported by Juanma Barranquero <lekktu@gmail.com>.
6201 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
6203 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
6204 * lisp.h (enum pvec_type): Use fewer bits.
6205 (PSEUDOVECTOR_SIZE_BITS): New constant.
6206 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
6207 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
6208 change in pvec_type.
6209 (PSEUDOVECTOR_TYPEP): New macro.
6210 (TYPED_PSEUDOVECTORP): Use it.
6211 * fns.c (internal_equal): Adapt code to extract pvectype.
6212 * emacs.c (gdb_pvec_type): Update type.
6213 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
6214 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
6215 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
6216 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
6217 (sweep_vectors): Use it. Use local var `total_bytes' instead of
6218 abusing vector->header.next.nbytes.
6219 (live_vector_p): Use PVEC_TYPE.
6220 (mark_object): Adapt code to extract pvectype. Use switch.
6222 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
6224 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
6225 Tighten new eassert a bit.
6227 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
6229 Fix compilation with --enable-gcc-warnings and -O1
6231 * doprnt.c (doprnt): Change type of tem to int, initialize
6232 to avoid compiler warning. Add eassert.
6233 * search.c (simple_search): Initialize match_byte to avoid
6234 compiler warning. Add eassert.
6236 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
6238 Avoid weird behavior with large horizontal scrolls.
6239 Without this change, for example, large hscroll values would
6240 mess up Emacs's display on Fedora 15 x86, presumably due to
6241 overflows in int calculations in the display code.
6242 Also, if buffers had long lines, Emacs would freeze.
6243 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
6244 (set_window_hscroll): New function, containing the old guts of
6245 Fset_window_hscroll. Return the clipped value.
6246 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
6247 This avoids the need to check against PTRDIFF_MAX.
6249 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
6251 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
6253 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
6255 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
6257 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
6258 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
6259 since GCC 4.4.6 issues a bogus warning for them.
6261 Fix bugs in file timestamp newness comparisons.
6262 * fileio.c (Ffile_newer_than_file_p):
6263 * lread.c (Fload): Use full timestamp resolution of files,
6264 not just the 1-second resolution, so that files that are only
6265 slightly newer still count as newer.
6266 * fileio.c (Ffile_newer_than_file_p): Don't assume file
6267 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
6269 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
6271 * fileio.c: Improve handling of file time marker. (Bug#11852)
6272 (special_mtime): New function.
6273 (Finsert_file_contents, Fverify_visited_file_modtime):
6274 Use it to set special mtime values consistently.
6276 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
6278 * fileio.c (Finsert_file_contents): Properly handle st_mtime
6279 marker for non-existing file. (Bug#11852)
6281 2012-07-03 Glenn Morris <rgm@gnu.org>
6283 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
6284 and did not make it into globals.h).
6286 2012-07-03 Tom Tromey <tromey@redhat.com>
6288 * window.c (Fset_window_margins, Fset_window_fringes)

6333 values which aren't power of 2.
6334 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
6335 Verify it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
6338 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
6340 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.

6344 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
6346 * alloc.c (allocate_vector_block): Remove redundant
6347 calls to mallopt if DOUG_LEA_MALLOC is defined.
6348 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
6349 avoid calls to mallopt if zero_vector is returned.
6351 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
6353 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
6354 is enabled, avoid dereferencing NULL current_sblock if
6357 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
6359 Cleanup basic buffer management.
6360 * buffer.h (struct buffer): Change layout to use generic vector
6361 marking code. Fix some comments. Change type of 'clip_changed'
6362 to bitfield. Remove unused #ifndef old.
6363 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
6364 (GET_OVERLAYS_AT): Fix indentation.
6365 (for_each_per_buffer_object_at): New macro.

6369 * alloc.c (allocate_buffer): Adjust to match new layout of
6370 struct buffer. Fix comment.
6371 (mark_overlay): New function.
6372 (mark_buffer): Use it. Use mark_vectorlike to mark normal
6373 Lisp area of struct buffer.
6374 (mark_object): Use it. Adjust marking of misc objects
6375 and related comments.
6377 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
6379 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
6380 wrapper that is not needed because the wrapped code is a no-op (zero
6381 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
6382 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
6384 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
6386 * alloc.c (mark_buffer): Simplify. Remove prototype.
6387 (mark_object): Add comment. Reorganize marking of vector-like
6388 objects. Use CHECK_LIVE for all vector-like objects except buffers
6389 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
6390 Avoid redundant calls to mark_vectorlike for bool vectors.
6392 2012-06-30 Glenn Morris <rgm@gnu.org>
6394 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
6396 * epaths.in (PATH_SITELOADSEARCH): New.
6397 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
6398 This is rather than relying on --enable-locallisppath elements
6399 having "site-lisp" in their names. (Bug#10208#25, 11658)
6401 2012-06-30 Eli Zaretskii <eliz@gnu.org>
6403 * w32proc.c (sys_select): Accept and ignore one more argument.
6405 * w32.c (emacs_gnutls_pull): Call select with one more argument.
6407 * sysselect.h [DOS_NT]: Don't include sys/select.h.
6408 (pselect) [!MS_DOS]: Redirect to sys_select.
6410 * sysdep.c: Don't include dos.h and dosfns.h.
6412 * process.c (sys_select):
6413 * msdos.c (sys_select): Accept one more argument and ignore it.
6415 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
6416 adapt data types and code to that.
6419 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
6420 which clashes with the gnulib function of the same name.
6422 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
6424 * font.c (font_style_to_value, font_style_symbolic)
6425 (font_prop_validate_style): Add type checks for values in
6428 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
6430 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
6433 2012-06-29 Eli Zaretskii <eliz@gnu.org>
6435 * xdisp.c (try_window_id): Undo last change.
6437 * w32.c (getwd): Adjust commentary about startup_dir.
6438 (init_environment): Always call sys_access, even in non-MSVC
6439 builds. Don't chdir to the directory of the Emacs executable.
6440 This undoes code from 1997 which was justified by the need to
6441 "avoid conflicts when removing and renaming directories". But its
6442 downside was that every relative file name was being interpreted
6443 relative to the directory of the Emacs executable, which can never
6444 be TRT. In particular, it broke sys_access when called with
6445 relative file names.
6446 (sys_access): Map GetLastError to errno.
6448 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
6450 * window.h (struct window): Change type of 'fringes_outside_margins'

6454 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
6457 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>

6460 Add QUIT to make the loop interruptible.
6462 2012-06-29 Glenn Morris <rgm@gnu.org>
6464 * charset.c (init_charset): Make lack of etc/charsets fatal.
6466 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
6468 * editfns.c (region_limit): Fix type mismatch.
6470 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
6472 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
6473 undefined. Convert from xassert to eassert.
6474 * nsmenu.m: Convert from xassert to eassert.

6481 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
6483 Avoid integer overflow on scroll-left and scroll-right.
6484 * window.c (HSCROLL_MAX): New macro.
6485 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
6486 overflow when requested scroll falls outside ptrdiff_t range.

6490 * window.h (struct window): Change type of 'hscroll',
6491 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
6492 'last_modified' and 'last_overlay_modified' to EMACS_INT.
6493 Adjust users accordingly.
6494 * xdisp.c (try_cursor_movement): Replace type check with eassert.
6495 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
6496 from EMACS_INT to ptrdiff_t.

6503 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>

6572 * alloc.c (allocate_string): Omit intervals initialization.
6573 * alloc.c (make_uninit_multibyte_string): Initialize intervals

6632 a better opportunity to optimize away calls to strlen when the

6634 * image.c (imagemagick_error): Convert to build_string.
6635 * w32proc.c (sys_spawnve): Likewise.

6638 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
6640 Use sprintf return value instead of invoking strlen on result.
6641 In the old days this wasn't portable, since some sprintf
6642 implementations returned char *. But they died out years ago and
6643 Emacs already assumes sprintf returns int.
6644 Similarly for float_to_string.
6645 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
6646 * ccl.c (ccl_driver):

6653 Use sprintf or float_to_string result to avoid need to call strlen.
6654 * data.c (Fnumber_to_string):
6655 Use make_unibyte_string, since the string must be ASCII.
6656 * lisp.h, print.c (float_to_string): Now returns int length.
6657 * term.c (produce_glyphless_glyph):
6658 Use sprintf result rather than recomputing it.
6660 Clean out last vestiges of the old HAVE_CONFIG_H stuff.

6693 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

6696 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
6698 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
6699 instead of truncating it to 63 (admittedly a generous limit).
6701 * process.c: Fix spelling and caps in comments.
6703 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>

6759 * keyboard.c (kbd_buffer_get_event):
6760 * process.c (Faccept_process_output):

6829 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
6831 Support higher-resolution time stamps (Bug#9000).
6832 The time stamps are only nanosecond-resolution at the C level,
6833 since that's the best that any real-world system supports now.
6834 But they are picosecond-resolution at the Lisp level, as that's
6835 easy, and leaves room for future OS improvements.
6837 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
6840 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
6841 Don't get current time unless it's needed.
6843 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
6844 now provides it if it's absent.
6845 (start_atimer): Port to higher-res time stamps.
6846 Check for time stamp overflow. Don't get current time more
6847 often than is needed.
6849 * buffer.h (struct buffer): Buffer modtime now has high resolution.
6850 Include systime.h, not time.h.
6851 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
6853 * dired.c: Include stat-time.h.
6854 (Ffile-attributes): File times now have higher resolution.

6857 (struct image): Timestamp now has higher resolution.
6859 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
6860 has at least microseconds now. All uses removed.
6861 (update_frame, update_single_window, update_window, update_frame_1)
6862 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
6863 (duration_to_sec_usec): Remove; no longer needed.

6872 (make_time): Now static.
6873 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
6874 Report an error if the time is invalid, rather than having the caller
6877 * fileio.c: Include <stat-time.h>
6878 (Fcopy_file): Copy higher-resolution time stamps.
6879 Prefer to set the time stamp via a file descriptor if that works.

6881 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
6882 (Fvisited_file_modtime, Fset_visited_file_modtime):
6883 Support higher-resolution time stamps.
6885 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
6887 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
6889 * image.c (prepare_image_for_display, clear_image_cache)
6890 (lookup_image): Port to higer-resolution time stamps.
6892 * keyboard.c (start_polling, bind_polling_period):
6893 Check for time stamp overflow.
6894 (read_char, kbd_buffer_get_event, timer_start_idle)
6895 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
6896 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
6897 Port to higher-resolution time stamps. Do not assume time_t is signed.
6898 (decode_timer): New function. Timers are now vectors of length 9,
6899 not 8, to accommodate the picosecond component.
6900 (timer_check_2): Use it.
6902 * nsterm.m (select_timeout, timeval_subtract): Remove.
6903 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
6904 as they're a bit more accurate and handle overflow better.
6905 (ns_select): Change prototype to be compatible with pselect.
6906 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
6907 * nsterm.h (ns_select): Adjust prototype.
6909 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
6910 us-resolution time stamps.
6911 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
6913 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
6915 * lisp.h (time_overflow): New decl.
6916 (wait_reading_process_output): First arg is now intmax_t, not int,
6917 to accommodate larger waits.
6919 * process.h (struct Lisp_Process.read_output_delay):
6920 Now counts nanoseconds, not microseconds.
6921 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
6923 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
6924 (wait_reading_process_output):

6926 (Faccept_process_output, wait_reading_process_output):
6927 Check for time stamp overflow. Do not assume time_t is signed.
6928 (select_wrapper): Remove; we now use pselect.
6929 (Fprocess_attributes): Now generates ns-resolution time stamps.
6931 * sysdep.c: Include utimens.h. Don't include utime.h
6932 or worry about struct utimbuf; gnulib does that for us now.
6933 (gettimeofday): Remove; gnulib provides a substitute.
6934 (make_timeval): New function.
6935 (set_file_times): Now sets ns-resolution time stamps.
6936 New arg FD; all uses changed.
6937 (time_from_jiffies, ltime_from_jiffies, get_up_time)
6938 (system_process_attributes):
6939 Now returns ns-resolution time stamp. All uses changed.
6940 Check for time stamp overflow.
6942 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
6943 provides a substitute now.
6945 * systime.h: Include timespec.h rather than sys/time.h and time.h,
6946 since it guarantees struct timespec.
6947 (EMACS_TIME): Now struct timespec, so that we can support
6948 ns-resolution time stamps.
6949 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
6950 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
6951 (EMACS_USECS): Remove.
6952 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
6953 so multiply the arg by 1000 before storing it.
6954 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
6956 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
6957 Port to ns-resolution time stamps.
6958 (EMACS_TIME_NEG_P): Remove; replaced by....
6959 (EMACS_TIME_SIGN): New macro.
6960 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
6961 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
6962 (set_file_times, make_time, lisp_time_argument): Adjust signature.
6963 (make_timeval, make_lisp_time, decode_time_components): New decls.
6964 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
6965 that it mishandled time_t overflow. You can't compare by subtracting!
6966 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
6967 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.

6975 (Fprimitive_undo): Use them when restoring time stamps.
6977 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
6978 (w32_get_internal_run_time):
6979 Port to higher-resolution Emacs time stamps.
6980 (ltime): Now accepts single 64-bit integer, as that's more convenient
6983 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
6985 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
6986 for compatibility with pselect. Support ns-resolution time stamps.
6988 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
6990 * xselect.c (wait_for_property_change, x_get_foreign_selection):
6991 Check for time stamp overflow, and support ns-resolution time stamps.
6993 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
6994 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
6995 (timeval_subtract): Remove; no longer needed.
6996 (XTflash, XTring_bell, x_wait_for_event):
6997 Port to ns-resolution time stamps. Don't assume time_t is signed.

7003 2012-06-22 Eli Zaretskii <eliz@gnu.org>
7005 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
7006 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
7007 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
7008 staticidx goes up to 1597 out of 1600 = 0x640.)
7010 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
7012 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
7013 Otherwise, the umask might be mistakenly 0 while handling input signals.

7058 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
7059 gets killed during executing of this function (Bug#11665).
7060 Try to always return Qt when the buffer has been actually killed.
7061 (Vkill_buffer_query_functions): In doc-string say that functions
7062 run by this hook should not change the current buffer.
7064 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

7087 This removes the need for CHECK.
7088 (CHECK): Remove. Its comments about always evaluating its
7089 argument were confusing, as 'eassert' typically does not evaluate
7092 * coding.c (produce_chars): Use ptrdiff_t, not int.
7094 * xterm.c (x_draw_underwave): Check for integer overflow.
7095 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

7255 * w32heap.c (allocate_heap): Don't check USE_LISP_UNION_TYPE.
7256 (init_heap): Likewise.
7257 * w32term.c (w32_read_socket): Update comment.
7259 2012-06-13 Glenn Morris <rgm@gnu.org>
7261 * s/usg5-4-common.h, src/s/unixware.h:
7262 Remove define/undef of HAVE_SYSV_SIGPAUSE (not used since 2010-05-04).
7264 * s/gnu.h (POSIX_SIGNALS): Remove (not used since 2010-05-04).
7266 2012-06-13 Paul Eggert <eggert@cs.ucla.edu>
7268 USE_LISP_UNION_TYPE + USE_LSB_TAG cleanup (Bug#11604)
7269 * alloc.c (make_number) [!defined make_number]:
7270 Remove, as lisp.h always defines this now.
7271 (mark_maybe_pointer): Simplify since USE_LSB_TAG is always defined now.
7272 (roundup_size): Verify that it is a power of 2.
7273 * data.c (Fmake_variable_buffer_local, Fmake_local_variable):
7274 * ftfont.c (ftfont_driver): Use LISP_INITIALLY_ZERO.
7275 * lisp.h (USE_LSB_TAG): Allow the builder to compile with
7276 -DUSE_LSB_TAG=0, to override the automatically-selected default.
7277 USE_LSB_TAG now is always defined to be either 0 or 1.
7279 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
7280 code works fine either way, and efficiency is not a concern here,
7281 as the union type is for debugging, not for production.
7282 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
7283 Use an inline function on all platforms when using the union type,
7284 since this is simpler and 'static inline' can be used portably
7286 (LISP_INITIALLY_ZERO): New macro.
7287 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
7288 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.

7305 MagickMergeImageLayers is undefined. Use pixel pusher loop if
7306 MagickExportImagePixels is undefined.

7314 * s/aix4-2.h, s/bsd-common.h, s/cygwin.h, s/darwin.h:
7315 * s/gnu-kfreebsd.h, s/gnu-linux.h, s/gnu.h, s/hpux10-20.h:
7316 * s/irix6-5.h, s/ms-w32.h, s/msdos.h, s/template.h:
7317 * s/usg5-4-common.h: Move SYSTEM_TYPE to configure.
7319 2012-06-11 Stefan Monnier <monnier@iro.umontreal.ca>
7321 * alloc.c (make_byte_code): New function.
7322 (Fmake_byte_code): Use it. Don't purify here.

7325 2012-06-11 Chong Yidong <cyd@gnu.org>
7327 * image.c (imagemagick_load_image): Implement transparency.
7329 2012-06-10 Andreas Schwab <schwab@linux-m68k.org>

7354 2012-06-09 Michael Albinus <michael.albinus@gmx.de>
7356 * dbusbind.c (XD_BASIC_DBUS_TYPE): Use dbus_type_is_valid and
7357 dbus_type_is_basic if available.
7358 (xd_extract_signed, xd_extract_unsigned): Rename from
7359 extract_signed and extract_unsigned, respectively. Adapt callers.
7361 2012-06-09 Chong Yidong <cyd@gnu.org>
7363 * xfaces.c (face_for_overlay_string): Handle face remapping (Bug#2066).
7365 * fringe.c (Fset_fringe_bitmap_face): Handle the noninteractive
7368 2012-06-08 Paul Eggert <eggert@cs.ucla.edu>
7370 * xdisp.c (vmessage): Treat frame message as multibyte.
7371 Without this change, (let ((§ 1)) (make-variable-buffer-local '§))
7372 would generate the diagnostic "Making \302\247 buffer-local while
7375 2012-06-08 Eli Zaretskii <eliz@gnu.org>
7377 * dispnew.c (showing_window_margins_p): Undo last change, which

7388 2012-06-08 Juanma Barranquero <lekktu@gmail.com>
7390 * dispnew.c (showing_window_margins_p): Wrap in #if 0 to prevent unused
7391 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
7393 2012-06-08 Eli Zaretskii <eliz@gnu.org>
7395 * alloc.c (allocate_vectorlike): Fix last change.
7397 2012-06-08 Dmitry Antipov <dmantipov@yandex.ru>
7399 Block-based vector allocation of small vectors.
7400 * lisp.h (struct vectorlike_header): New field `nbytes',
7401 adjust comment accordingly.
7402 * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'
7403 to denote vector blocks. Adjust users (live_vector_p,
7404 mark_maybe_pointer, valid_lisp_object_p) accordingly.
7405 (COMMON_MULTIPLE): Move outside #if USE_LSB_TAG.
7406 (VECTOR_BLOCK_SIZE, vroundup, VECTOR_BLOCK_BYTES),
7407 (VBLOCK_BYTES_MIN, VBLOCK_BYTES_MAX, VECTOR_MAX_FREE_LIST_INDEX),
7408 (VECTOR_FREE_LIST_FLAG, ADVANCE, VINDEX, SETUP_ON_FREE_LIST),
7409 (VECTOR_SIZE, VECTOR_IN_BLOCK): New macros.

7419 (Fgarbage_collect): Move all vector sweeping code to sweep_vectors.
7420 (init_alloc_once): Add call to init_vectors.

7424 * eval.c (Fmacroexpand): Stop if the macro returns the same form.
7426 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
7428 * doprnt.c (doprnt): Truncate multibyte char correctly.
7429 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
7430 would mishandle a string argument "Xc" if X was a multibyte
7431 character of length 2: it would truncate after X's first byte
7432 rather than including all of X.
7434 2012-06-06 Chong Yidong <cyd@gnu.org>
7436 * buffer.c (word_wrap): Doc fix.
7438 2012-06-04 Paul Eggert <eggert@cs.ucla.edu>

7483 * minibuf.c (Fassoc_string): Remove duplicate declaration.
7485 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
7486 Convert pctcpu and pctmem to Lisp float properly.
7487 Let the compiler fold better, as 100.0/0x8000 is exact.
7489 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
7491 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
7494 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
7496 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
7498 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
7500 For a 'struct window', replace some Lisp_Object fields to
7501 bitfields where appropriate, remove unused fields.
7502 * window.h (struct window): Remove unused 'last_mark_x' and
7503 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
7504 change it's type from Lisp_Object to bitfield.
7505 Change type of 'force_start', 'optional_new_start',
7506 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
7507 fields from Lisp_Object to bitfield. Adjust users accordingly.
7509 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
7511 Pacify gcc -Wdouble-precision when using Xaw.
7512 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
7513 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
7514 Use 'float' consistently, rather than 'float' in most places
7515 and 'double' in a couple of places.
7517 2012-05-31 Eli Zaretskii <eliz@gnu.org>
7519 * xdisp.c (handle_stop): Detect whether we have overlay strings
7520 loaded by testing it->current.overlay_string_index to be
7521 non-negative, instead of checking whether n_overlay_strings is
7522 positive. (Bug#11587)
7524 2012-05-31 Chong Yidong <cyd@gnu.org>
7526 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
7528 * doc.c (Fsubstitute_command_keys): Doc fix.
7530 2012-05-31 Eli Zaretskii <eliz@gnu.org>
7532 * search.c (search_buffer): Remove calls to
7533 r_alloc_inhibit_buffer_relocation, as it is now called by
7534 maybe_unify_char, which was the cause of relocation of buffer text
7537 2012-05-31 Eli Zaretskii <eliz@gnu.org>
7539 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
7540 for the duration of call to load_charset, to avoid problems with
7541 callers of maybe_unify_char that access buffer text through C
7544 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
7545 decrement the inhibition flag, instead of just setting or
7548 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
7550 Remove obsolete '#define static' cruft.
7551 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
7552 This #undef was "temporary" in 2000; it is no longer needed
7553 now that '#define static' has gone away.
7554 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
7555 (gray_bitmap_bits): Remove; no longer needed.
7556 All uses replaced with definiens.
7557 * xterm.c: Include "bitmaps/gray.xbm".
7559 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
7561 Clean up __executable_start, monstartup when --enable-profiling.
7562 The following changes affect the code only when profiling.
7563 * dispnew.c (__executable_start): Rename from safe_bcopy.
7564 Define only on platforms that need it.
7565 * emacs.c: Include <sys/gmon.h> when profiling.
7566 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
7567 (__executable_start): Remove decl, since lisp.h does it now.
7568 (safe_bcopy): Remove decl; no longer has that name.
7569 (main): Coalesce #if into single bit of code, for simplicity.
7570 Cast pointers to uintptr_t, since standard libraries want integers

7594 * lisp.h (Qdefun): Remove.
7595 * lread.c (read1): Tiny simplification.
7597 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
7599 Do not create empty overlays with the evaporate property (Bug#9642).
7600 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
7601 Bug#9642, but explicitly check that the buffer the overlay would
7602 be moved to is live and rearrange lines to make sure that errors
7603 will not put the overlay in an inconsistent state.
7604 (Fdelete_overlay): Cosmetics.
7606 2012-05-28 Eli Zaretskii <eliz@gnu.org>
7608 * w32term.c (my_bring_window_to_top): New function.
7609 (x_raise_frame): Use handle returned by DeferWindowPos, which
7610 could be different from the original one.
7611 Call my_bring_window_to_top instead of my_set_foreground_window.
7614 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
7615 by calling BringWindowToTop.

7620 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
7622 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
7623 This avoids undefined behavior that might cause the eassert
7624 to not catch an out-of-range value.
7626 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
7628 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

7638 when referring to sectname field in printf format.
7640 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
7642 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
7643 Only r_alloc_inhibit_buffer_relocation needed to be added;
7644 the others were already declared.
7646 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
7647 before checking whether it's out of range. Put the check inside
7649 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
7651 2012-05-27 Ken Brown <kbrown@cornell.edu>
7653 * callproc.c (Fcall_process): Restore a line that was accidentally
7654 commented out in the 2011-02-13 change (bug#11547).

7658 * lisp.h [REL_ALLOC]: Add prototypes for external functions
7659 defined on ralloc.c.
7661 * buffer.c [REL_ALLOC]: Remove prototypes of
7662 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
7663 they are now on lisp.h.
7665 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
7667 * search.c (search_buffer): Use it to inhibit relocation of buffer
7668 text while re_search_2 is doing its job, because re_search_2 is
7669 passed C pointers to buffer text. (Bug#11519)
7671 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
7674 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
7675 state after an additional call to move_it_in_display_line_to, keep
7676 the values of it->max_ascent and it->max_descent found for the
7678 (pos_visible_p): Revert the comparison against bottom_y to what it
7679 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
7682 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
7684 Fix coding-related core dumps with gcc -ftrapv.
7685 The code was computing A - B, where A and B are pointers, and B is
7686 random garbage. This can lead to core dumps on platforms that
7687 have special pointer registers, and it also leads to core dumps on
7688 x86-64 when compiled with gcc -ftrapv. The fix is to compute
7689 A - B only when B is initialized properly.
7690 * coding.c (coding_set_source, coding_set_destination): Return void.
7691 (coding_change_source, coding_change_destinations): New functions,
7692 with the old behaviors of coding_set_source and coding_set_destination.
7693 All callers that need an offset changed to use these new functions.
7695 2012-05-26 Glenn Morris <rgm@gnu.org>
7697 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
7699 2012-05-26 Eli Zaretskii <eliz@gnu.org>
7701 Extend mouse support on W32 text-mode console.
7702 * xdisp.c (draw_row_with_mouse_face):
7703 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
7705 * w32console.c: Include window.h.
7706 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
7708 (initialize_w32_display): Initialize mouse-highlight data.
7710 * w32inevt.c: Include termchar.h and window.h.
7711 (do_mouse_event): Support mouse-autoselect-window. When the mouse
7712 moves, call note_mouse_highlight. If help_echo changed, call
7713 gen_help_event to produce help-echo message in the echo area.
7714 Call clear_mouse_face if mouse_face_hidden is set in the mouse
7717 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
7719 * lread.c (read1): Simplify slightly to avoid an overflow warning
7720 with GCC 4.7.0 on x86-64.
7722 2012-05-26 Eli Zaretskii <eliz@gnu.org>
7724 * bidi.c (bidi_mirror_char): Revert last change: an int is
7725 definitely wide enough here.
7727 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
7729 Fix integer width and related bugs (Bug#9874).
7730 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
7731 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)

7762 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
7763 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
7764 (validate_region): Omit unnecessary test for b <= e,
7765 since that's guaranteed by the previous test.

7767 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
7768 (report_overlay_modification):

7779 not int, to avoid needless 32-bit limit on 64-bit hosts.
7780 (exec_byte_code): Use tighter memory-full test, one that checks
7781 for alloca overflow. Don't compute the address of the object just
7782 before an array, as that's not portable. Use EMACS_INT, not
7783 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
7784 * callint.c (Fcall_interactively):
7785 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

7798 (casify_object): Avoid integer overflow when overallocating buffer.
7799 * casetab.c (set_identity, shuffle): Prefer int to unsigned when

7802 * category.h (CATEGORYP): Don't assume arg is nonnegative.
7803 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the

7806 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
7807 For CCL_MapSingle, check that content and value are in int range.

7809 Check that Vcode_version_map_vector is a vector.
7810 (resolve_symbol_ccl_program): Check that vector header is in range.
7811 Always copy the vector, so that we can check its contents reliably
7812 now rather than having to recheck each instruction as it's being
7813 executed. Check that vector words fit in 'int'.
7814 (ccl_get_compiled_code, Fregister_ccl_program)
7815 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
7816 program indexes, to avoid needless 32-bit limit on 64-bit hosts.

7818 contents are in range.
7819 (Fccl_execute_on_string): Check that status is in range.
7820 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
7821 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
7822 Accept and return EMACS_INT, not int, because callers can pass values

7829 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

7831 avoid mishandling large integers.

7843 Don't assume unsigned int fits into fixnum, or that fixnum fits
7844 into unsigned int. Don't require max_code to be a valid fixnum;
7845 that's not true for gb10830 4-byte on a 32-bit host. Allow
7846 invalid_code to be a cons, for the same reason. Require code_offset
7847 to be a character. Avoid int overflow if max_char is close
7849 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
7850 this is intended anyway and avoids some undefined behavior.
7851 (load_charset_map): Pass unsigned, not int, as 2nd arg of
7852 INDEX_TO_CODE_POINT, as that's what it expects.
7853 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
7854 * charset.h (DECODE_CHAR): Return int, not unsigned;
7855 this is what was intended anyway, and it avoids undefined behavior.
7856 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
7857 integer-overflow issues.
7858 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
7859 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
7860 where the argument is EMACS_INT, and this behavior is not intended.
7861 * chartab.c (Fmake_char_table, Fset_char_table_range)
7862 (uniprop_get_decoder, uniprop_get_encoder):
7863 Don't assume fixnum fits in int.
7864 * cmds.c (move_point): New function, that does the gist of
7865 Fforward_char and Fbackward_char, but does so while checking
7866 for integer overflow more accurately.
7867 (Fforward_char, Fbackward_char): Use it.
7868 (Fforward_line, Fend_of_line, internal_self_insert)
7869 (internal_self_insert):
7870 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

8529 2012-05-25 Glenn Morris <rgm@gnu.org>
8531 * lisp.mk (lisp): Update for more files being compiled now.
8533 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>
8535 * lread.c: Remove `read_pure' which makes no difference.
8536 (read_pure): Remove var.
8537 (unreadpure): Remove function.
8538 (readevalloop): Don't call read_list with -1 flag.
8539 (read1, read_vector): Don't test read_pure any more.
8540 (read_list): Simplify.

8551 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
8553 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
8556 This directory predates autoconf and is no longer needed nowadays.
8557 Move its few remaining bits of functionality to where they're needed.
8558 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:

8568 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
8569 (BITS_PER_EMACS_INT): New constants, replacing
8570 what used to be in config.h, but not useful in #if.
8571 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
8572 define them any more.
8573 (VAL_MAX): New macro.
8575 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
8576 BITS_PER_EMACS_INT, in #if.
8577 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
8578 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
8579 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
8580 * s/ms-w32.h (DATA_START):
8581 Move here from removed file m/intel386.h.
8582 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
8583 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
8585 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
8587 Assume C89 or later.
8588 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.

8596 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
8597 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
8598 * xterm.c (input_signal_count): Assume volatile works.
8600 2012-05-21 Ken Brown <kbrown@cornell.edu>
8602 * xgselect.c (xg_select): Fix first argument in call to 'select'
8605 2012-05-20 Ken Brown <kbrown@cornell.edu>
8607 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
8608 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
8610 2012-05-19 Ken Brown <kbrown@cornell.edu>
8612 * xfns.c (x_in_use): Remove `static' qualifier.
8613 * xterm.h (x_in_use): Declare.
8614 * xgselect.c: Include xterm.h.
8615 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
8616 and `display_arg' (bug#9754).
8618 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
8620 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
8622 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
8623 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
8625 2012-05-18 Eli Zaretskii <eliz@gnu.org>
8627 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
8629 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
8630 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
8632 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
8633 reference to image_cache->refcount.
8634 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
8636 2012-05-17 Juri Linkov <juri@jurta.org>
8638 * search.c (Fword_search_regexp, Fword_search_backward)
8639 (Fword_search_forward, Fword_search_backward_lax)
8640 (Fword_search_forward_lax): Move functions to isearch.el
8641 (bug#10145, bug#11381).
8643 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
8645 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
8647 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
8649 * lread.c (init_obarray): Declare Qt and Qnil as special.
8651 2012-05-14 Glenn Morris <rgm@gnu.org>
8653 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
8654 Put "libexec" before "bin", for the sake of init_callproc_1.
8656 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
8658 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
8660 * unexaix.c: Port to more-recent AIX compilers.
8661 (report_error, report_error_1, make_hdr, copy_sym)
8662 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
8663 Make arguments const char *, not char *, to avoid violations of C
8664 standard and to fix some AIX warnings reported by Gilles Pion.
8666 2012-05-14 Eli Zaretskii <eliz@gnu.org>
8668 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
8669 already have overlays loaded.
8670 (handle_single_display_spec): Before returning without displaying
8671 fringe bitmap, synchronize the bidi iterator with the main display
8672 iterator, by calling iterate_out_of_display_property.
8673 (iterate_out_of_display_property): Detect buffer iteration by
8674 testing that it->string is a Lisp string.
8675 (get_next_display_element): When the current object is exhausted,
8676 and there's something on it->stack, call set_iterator_to_next to
8677 proceed with what's on the stack, instead of returning zero.
8678 (set_iterator_to_next): If called at the end of a Lisp string,
8679 proceed to consider_string_end without incrementing string
8680 position. Don't increment display vector index past the end of
8681 the display vector. (Bug#11417)
8682 (pos_visible_p): Don't report a position visible when move_it_to
8683 stopped at the last line of window, which happens to be scanned
8684 backwards by the bidi iteration. (Bug#11464)
8686 2012-05-14 Eli Zaretskii <eliz@gnu.org>
8688 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
8689 and right-margin display specs even if the spec is invalid or we
8690 are on a TTY, and thus unable to display on the fringes.
8691 That's because the text with the property will not be displayed anyway,
8692 so we need to signal to the caller that this is a "replacing"
8693 display spec. This fixes display when the spec is invalid or we
8696 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
8698 * unexaix.c (make_hdr): Fix typo in prototype.
8699 This bug broke the build on AIX. Problem reported by Gilles Pion.
8701 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
8703 * keyboard.c (kbd_buffer_get_event): Read special events also in
8704 batch mode. (Bug#11415)
8706 2012-05-12 Glenn Morris <rgm@gnu.org>
8708 * ns.mk: Update for ns_appbindir no longer having trailing "/".
8710 2012-05-12 Eli Zaretskii <eliz@gnu.org>
8712 * lisp.mk (lisp): Add newcomment.elc.
8714 2012-05-12 Glenn Morris <rgm@gnu.org>
8716 * Makefile.in (MKDIR_P): New, set by configure.
8717 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
8719 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
8721 Remove unused function hourglass_started.
8722 * dispextern.h (hourglass_started):
8723 * w32fns.c (hourglass_started):
8724 * xdisp.c (hourglass_started): Remove.
8726 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
8728 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
8729 Update dependencies.
8731 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
8733 * xgselect.c (xg_select): Put maxfds+1 into a var.
8734 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
8736 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
8738 2012-05-10 Dave Abrahams <dave@boostpro.com>
8740 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
8741 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
8743 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
8745 * dbusbind.c (xd_registered_buses): New internal Lisp object.
8746 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
8747 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
8748 Initialize xd_registered_buses.
8750 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
8752 Untag more efficiently if USE_LSB_TAG.
8753 This is based on a proposal by YAMAMOTO Mitsuharu in
8754 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
8755 For an admittedly artificial (nth 8000 longlist) benchmark on
8756 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
8757 Emacs's overall text size by 1%.
8758 * lisp.h (XUNTAG): New macro.
8759 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
8760 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
8761 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
8762 * eval.c (Fautoload):
8763 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
8764 * frame.h (XFRAME): Use XUNTAG.
8766 Port recent dbusbind.c changes to 32-bit --with-wide-int.
8767 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
8768 Remove unportable assumptions about print widths of types like
8770 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
8771 intptr_t when converting between pointer and integer, to avoid GCC
8772 warnings about wrong width.
8774 2012-05-09 Eli Zaretskii <eliz@gnu.org>
8776 * w32proc.c (new_child): Force Windows to reserve only 64KB of
8777 stack for each reader_thread, instead of defaulting to 8MB
8778 determined by the linker. This avoids failures in creating
8779 subprocesses on Windows 7, see the discussion in this thread:
8780 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
8782 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
8784 Fix up display of the *Minibuf-0* buffer in the mini window.
8785 * keyboard.c (read_char): Don't clear the echo area if there's no
8787 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
8788 contents of *Minibuf-0*) if there's no message displayed in its stead.
8790 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
8792 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
8795 2012-05-06 Chong Yidong <cyd@gnu.org>
8797 * lisp.mk (lisp): Update.
8799 2012-05-05 Jim Meyering <meyering@redhat.com>
8801 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
8803 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
8805 * data.c (PUT_ERROR): New macro.
8806 (syms_of_data): Use it. Add new error type `user-error'.
8807 * undo.c (user_error): New function.
8808 (Fprimitive_undo): Use it.
8809 * print.c (print_error_message): Adjust print style for `user-error'.
8810 * keyboard.c (user_error): New function.
8811 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
8813 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
8815 Do not limit current-time-string to years 1000..9999.
8816 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
8817 (Fcurrent_time_string): Support any year that is supported by the
8818 underlying localtime representation. Don't use asctime, as it
8819 has undefined behavior for years outside the range -999..9999.
8821 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
8823 Fix race conditions involving setenv, gmtime, localtime, asctime.
8824 Without this fix, interrupts could mess up code that uses these
8825 nonreentrant functions, since setting TZ invalidates existing
8826 tm_zone or tzname values, and since most of these functions return
8827 pointers to static storage.
8828 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
8829 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
8830 Grow the critical sections to include not just invoking
8831 localtime/gmtime, but also accessing these functions' results
8832 including their tm_zone values if any, and any related TZ setting.
8833 (format_time_string): Last arg is now struct tm *, not struct tm **,
8834 so that the struct tm is saved in the critical section.
8835 All callers changed. Simplify allocation of initial buffer, partly
8836 motivated by the fact that memory allocation needs to be outside
8837 the critical section.
8839 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
8841 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
8842 with RESET_INTERVAL.
8844 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
8845 Remove duplicated buffer name initialization.
8847 2012-05-02 Jim Meyering <jim@meyering.net>
8849 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
8851 * xfns.c (x_window): Use xstrdup (Bug#11375).
8853 2012-05-02 Eli Zaretskii <eliz@gnu.org>
8855 * xdisp.c (pos_visible_p): If already at a newline from the
8856 display string before the 'while' loop, don't walk back the glyphs
8857 from it3.glyph_row. Solves assertion violation when the display
8858 string begins with a newline (egg.el). (Bug#11367)
8860 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
8862 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
8865 2012-05-01 Glenn Morris <rgm@gnu.org>
8867 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
8868 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
8869 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
8870 All were removed before 23.1.
8872 * dispnew.c: Remove HAVE_LIBNCURSES test;
8873 it is always true on relevant platforms.
8875 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
8876 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
8878 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.

8886 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
8888 Do not avoid creating empty evaporating overlays (Bug#9642).
8889 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
8890 That is, do not delete an evaporating overlay if it becomes
8891 empty after its bounds are adjusted to fit within its buffer.
8892 This fix caused other problems, and I'm reverting it until we get
8893 to the bottom of them.
8895 2012-04-27 Chong Yidong <cyd@gnu.org>
8897 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
8899 2012-04-27 Eli Zaretskii <eliz@gnu.org>
8901 * xdisp.c (pos_visible_p): If the window start position is beyond
8902 ZV, start the display from buffer beginning. Prevents assertion
8903 violation in init_iterator when the minibuffer window is scrolled
8906 * window.c (window_scroll_pixel_based): Likewise.
8908 2012-04-27 Chong Yidong <cyd@gnu.org>

8922 2012-04-26 Eli Zaretskii <eliz@gnu.org>
8924 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
8925 display element, check also the underlying string or buffer
8926 character. (Bug#11341)
8928 * w32menu.c: Include w32heap.h.
8929 (add_menu_item): If the call to AppendMenuW (via
8930 unicode_append_menu) fails, disable Unicode menus only if we are
8931 running on Windows 9X/Me.
8933 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
8935 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.

8938 2012-04-24 Martin Rudalics <rudalics@gmx.at>
8940 * keyboard.c (read_char): Don't wipe echo area for select window
8941 events: These might get delayed via `mouse-autoselect-window'

8946 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
8947 manipulation of :loaded-from data.
8949 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
8951 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
8952 now a cons (bug#11311).
8954 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
8956 Do not create empty overlays with the evaporate property (Bug#9642).
8957 * buffer.c (Fmove_overlay): Delete an evaporating overlay
8958 if it becomes empty after its bounds are adjusted to fit within
8959 its buffer. Without this fix, in a nonempty buffer (let ((o
8960 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
8961 yields an empty overlay that has the evaporate property, which is
8962 not supposed to happen.
8964 Fix minor GTK3 problems found by static checking.
8965 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)

9079 * sysdep.c [__FreeBSD__]: Minor cleanups.
9080 (list_system_processes, system_process_attributes) [__FreeBSD__]:
9081 Use Emacs indenting style more consistently. Avoid some casts.
9082 Use 'double' consistently rather than mixing 'float' and 'double'.

9102 (print_object): Check for cycles even when print-circle is nil and
9103 print-gensym is t, but only check print_depth if print-circle is nil.
9105 2012-04-20 Chong Yidong <cyd@gnu.org>
9107 * process.c (wait_reading_process_output): If EIO occurs on a pty,
9108 set the status to "failed" and ensure that sentinel is run.

9236 2012-04-11 Daniel Colascione <dancol@dancol.org>
9238 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
9239 against is gone. It's better to use vfork now so that when Cygwin
9240 gains a new, working vfork, we use it automatically (bug#10398).
9242 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

9297 2012-04-09 Eli Zaretskii <eliz@gnu.org>
9299 * xdisp.c (set_cursor_from_row): If the display string appears in
9300 the buffer at position that is closer to point than the position
9301 after the display string, display the cursor on the first glyph of
9302 the display string. Fixes cursor display when a 'display' text
9303 property immediately follows invisible text. (Bug#11094)
9305 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
9307 composite.c: use 'double' consistently
9308 * composite.c (get_composition_id): Use 'double' consistently
9309 instead of converting 'float' to 'double' and vice versa; this is
9310 easier to understand and avoids a GCC warning.
9312 2012-04-09 Glenn Morris <rgm@gnu.org>
9314 * Makefile.in: Generate leim-list with bootstrap-emacs, in
9315 preparation for dumping it with emacs. (Bug#4789)

9337 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
9338 (mark_memory): Mark Lisp_Objects only if pointers might hide in
9339 objects, as mark_maybe_pointer will catch them otherwise.
9340 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
9341 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.

9359 [!WINDOWSNT]: New macros.
9360 (init_libxml2_functions, libxml2_loaded_p): New functions.
9361 (parse_region): Call fn_xmlCheckVersion instead of using the macro
9362 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
9363 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
9364 Calls xmlCleanupParser only if libxml2 was loaded (or statically
9366 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
9367 Call init_libxml2_functions before calling libxml2 functions.
9368 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
9370 * emacs.c: Don't include libxml/parser.h.

9385 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
9386 about subtle differences between FETCH_CHAR* and STRING_CHAR*
9387 macros related to unification of CJK characters. For the details,
9388 see the discussion following the message here:
9389 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
9391 2012-04-04 Chong Yidong <cyd@gnu.org>
9393 * keyboard.c (Vdelayed_warnings_list): Doc fix.
9395 2012-04-01 Eli Zaretskii <eliz@gnu.org>

9405 2012-03-31 Eli Zaretskii <eliz@gnu.org>
9407 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
9408 position we get to after a call to move_it_to fails the
9409 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
9410 only if we wind up in a string from display property. (Bug#11063)
9412 * window.c (Fdelete_other_windows_internal): Invalidate the row
9413 and column information about mouse highlight, so that redisplay
9414 restores it after reallocating the glyph matrices. (Bug#7464)
9416 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
9417 string comes from a `display' text property, use the buffer
9418 position of that property as if we actually saw that position in
9420 (move_it_by_lines): Remove the assertion that
9421 "it->current_x == 0 && it->hpos == 0" which can be legitimately
9422 violated when there's a before-string at the beginning of a line.
9425 2012-03-30 Eli Zaretskii <eliz@gnu.org>
9427 * xdisp.c (append_space_for_newline): If the default face was
9428 remapped, use the remapped face for the appended newline.
9429 (extend_face_to_end_of_line): Use the remapped default face for
9430 extending the face to the end of the line.
9431 (display_line): Call extend_face_to_end_of_line when the default
9432 face was remapped. (Bug#11068)
9434 2012-03-29 Eli Zaretskii <eliz@gnu.org>
9436 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.

9447 2012-03-26 Kenichi Handa <handa@m17n.org>
9449 * dispextern.h (struct glyph): Fix previous change. Change the
9450 bit length of glyphless.ch to 25 (Bug#11082).
9452 2012-03-26 Chong Yidong <cyd@gnu.org>
9454 * keyboard.c (Vselection_inhibit_update_commands): New variable.
9455 (command_loop_1): Use it; inhibit selection update for
9456 handle-select-window too (Bug#8996).
9458 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
9460 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
9462 2012-03-25 Kenichi Handa <handa@m17n.org>
9464 * dispextern.h (struct glyph): Change the bit length of
9465 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
9467 2012-03-24 Eli Zaretskii <eliz@gnu.org>
9469 * s/ms-w32.h (tzname): Include time.h before redirecting to
9470 _tzname. Fixes the MSVC build. (Bug#9960)
9472 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
9474 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
9477 * xterm.c (XTread_socket): Only modify handling_signal if
9478 !SYNC_INPUT. (Bug#11080)
9480 2012-03-23 Eli Zaretskii <eliz@gnu.org>
9482 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
9483 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
9484 when fetching a multibyte character consumes more bytes than
9485 CHAR_BYTES returns, due to unification of CJK characters in
9486 string_char. (Bug#11073)
9488 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
9490 * process.c (wait_reading_process_output): Handle pty disconnect
9491 by refraining from sending oneself a SIGCHLD (bug#10933).

9514 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
9515 to reflect default non-nil value of redisplay-dont-pause.
9517 2012-03-19 Kenichi Handa <handa@m17n.org>

9520 it fit in a valid range (Bug#11003).
9522 2012-03-18 Eli Zaretskii <eliz@gnu.org>
9524 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
9525 that is not from display property, accept the row as a "cursor
9526 row" if one of the string's character has a non-nil `cursor'
9527 property. Fixes cursor positioning when there are newlines in
9528 overlay strings, e.g. in icomplete.el. (Bug#11035)
9530 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>

9536 * eval.c (inhibit_lisp_code): Rename from
9537 inhibit_window_configuration_change_hook; move from window.c.
9539 * xfns.c (unwind_create_frame_1, Fx_create_frame):
9540 * window.c (run_window_configuration_change_hook)
9541 (syms_of_window): Callers changed.

9561 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
9564 2012-03-03 Glenn Morris <rgm@gnu.org>
9566 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
9568 2012-03-02 Eli Zaretskii <eliz@gnu.org>

9571 position past the first glyph_row that ends at ZV. (Bug#10902)
9572 (redisplay_window, next_element_from_string): Fix typos in
9574 (redisplay_window): Pass to move_it_vertically the margin in
9575 pixels, not in screen lines.
9577 2012-03-02 Glenn Morris <rgm@gnu.org>
9579 * buffer.c (buffer-list-update-hook): Doc fix.
9581 2012-02-29 Eli Zaretskii <eliz@gnu.org>
9583 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
9584 push_it before setting up the iterator for the first overlay
9585 string, even if we have an empty string loaded.
9586 (next_overlay_string): If there's an empty string on the iterator
9587 stack, pop the stack. (Bug#10903)
9589 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
9591 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
9592 Suggested by Stefan Monnier in
9593 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
9594 * alloc.c (widen_to_Lisp_Object): New static function.
9595 (mark_memory): Also mark Lisp_Objects by fetching pointer words
9596 and widening them to Lisp_Objects. This would work even if
9597 USE_LSB_TAG is defined and wide integers are used, which might
9598 happen in a future version of Emacs.
9600 2012-02-25 Chong Yidong <cyd@gnu.org>
9602 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
9605 * xselect.c (Fx_selection_exists_p): Doc fix.
9606 (x_clipboard_manager_save_all): Print an informative message
9607 before saving to clipboard manager.
9609 2012-02-24 Chong Yidong <cyd@gnu.org>
9611 * keyboard.c (process_special_events): Handle all X selection

9618 (unwind_create_frame_1): New helper function.
9620 * window.c (inhibit_window_configuration_change_hook): New var.
9621 (run_window_configuration_change_hook): Obey it.
9622 (syms_of_window): Initialize it.

9639 when computing $valmask.
9641 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
9642 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
9643 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
9644 It's useless in that case, and it can cause problems on hosts
9645 that allocate halves of EMACS_INT values separately.
9646 Reported by Dan Horák. Diagnosed by Andreas Schwab in
9647 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
9648 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
9649 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
9650 it avoids undefined behavior on hosts where shifting right by more
9651 than the word width has undefined behavior.
9653 2012-02-19 Chong Yidong <cyd@gnu.org>
9655 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
9656 (Funhandled_file_name_directory, Ffile_name_as_directory)

9675 2012-02-15 Chong Yidong <cyd@gnu.org>
9677 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is

9693 2012-02-12 Chong Yidong <cyd@gnu.org>
9695 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
9696 as that creates a dangerous corner case.
9698 * window.c (Fdelete_window_internal): Invalidate the mouse
9699 highlight (Bug#9904).
9701 2012-02-12 Glenn Morris <rgm@gnu.org>

9707 (Fx_disown_selection_internal, Fx_selection_exists_p)
9708 (Fx_selection_owner_p, Fx_get_selection_internal):
9709 Sync docs and argument specs with the xselect.c versions.

9733 * buffer.c (Fbuffer_local_variables)
9734 (buffer_lisp_local_variables): Handle unbound vars correctly;

9737 2012-02-07 Glenn Morris <rgm@gnu.org>
9739 * image.c (Fimagemagick_types): Doc fix.
9741 * image.c (imagemagick-render-type): Change it from a lisp object

9774 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
9776 Handle overflow when computing char display width (Bug#9496).
9777 * character.c (char_width): Return EMACS_INT, not int.
9778 (char_width, c_string_width): Check for overflow when
9779 computing the width; this is possible now that individual
9780 characters can have unbounded width. Problem introduced
9781 by merge from Emacs 23 on 2012-01-19.
9783 2012-02-02 Michael Albinus <michael.albinus@gmx.de>

10316 (ALIGN_GCTYPEBITS) [_MSC_VER]: Define.
10317 (DECL_ALIGN) [_MSC_VER]: Use it, as MSVC doesn't like bit ops in
10318 this macro definition.
10320 * s/ms-w32.h (tzname): Redirect to _tzname for all values of

10345 * xdisp.c (redisplay_window): If cursor row is not fully visible
10346 after recentering, and scroll-conservatively is set to a large
10347 number, scroll window by a few more lines to make the cursor fully
10348 visible and out of scroll-margin. (Bug#10105)
10349 (start_display): Don't move to the next line if the display should
10350 start at a newline that is part of a display vector or an overlay
10351 string. (Bug#10119)

10431 Otherwise, valgrind does not work on some platforms.
10432 Problem reported by Andreas Schwab in
10433 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
10434 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
10435 is set, removing the need for VIRT_ADDRESS_VARIES.
10436 (PURE_P): Use a more-efficient implementation that needs just one
10437 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
10438 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
10439 to 4 (xorl, subq, cmpq, setbe).
10440 * alloc.c (pure): Always extern now, since that's the
10441 VIRT_ADDR_VARIES behavior.

10443 consistency with the new puresize.h.
10444 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
10445 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

10451 (erase_phys_cursor, update_window_cursor, show_mouse_face)
10452 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
10453 behave as if the cursor position were at the window margin.
10455 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
10456 and the cursor position is out of bounds, behave as if the cursor
10457 position were at the window margin. (Bug#10075)
10459 2011-11-18 Chong Yidong <cyd@gnu.org>
10461 * window.c (Fwindow_combination_limit): Make first argument

10480 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
10482 * xdisp.c (row_hash): New function, body extracted from
10483 compute_line_metrics.
10484 (compute_line_metrics): Call row_hash, instead of computing the
10487 * dispnew.c (verify_row_hash): Call row_hash for computing the
10488 hash code of a row, instead of duplicating code from xdisp.c.
10490 * dispextern.h (row_hash): Add prototype.
10492 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
10494 * frame.c (delete_frame): Don't delete the terminal when the last

10519 (recombine_windows, make_parent_window, make_window)
10520 (Fsplit_window_internal, saved_window)
10521 (Fset_window_configuration, save_window_save): Rename all
10522 occurrences of window_nest to window_combination_limit.
10524 2011-11-15 Juanma Barranquero <lekktu@gmail.com>

10528 2011-11-14 Eli Zaretskii <eliz@gnu.org>
10530 * xdisp.c (display_line): Move the call to
10531 highlight_trailing_whitespace before the call to
10532 compute_line_metrics, since the latter needs to see the final
10533 faces of all the glyphs to compute ROW's hash value.
10534 Fixes assertion violations in row_equal_p. (Bug#10035)
10536 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
10538 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,
10539 just return (bug#10044).
10541 2011-11-12 Eli Zaretskii <eliz@gnu.org>
10543 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
10544 with user-defined heap size. Bump the default size of the temacs
10545 heap to 27MB, to avoid memory warning when running temacs.
10546 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
10548 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
10549 current_matrix and desired_matrix. (Bug#9990)
10550 (verify_row_hash) [XASSERTS]: New function.
10551 (adjust_glyph_matrix, row_equal_p): Use it in xassert to verify

10584 avoid a crash (bug#9496).
10586 2011-11-09 Chong Yidong <cyd@gnu.org>
10588 * window.c (Fwindow_inside_edges, Fwindow_inside_pixel_edges)

10595 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
10597 Avoid some portability problems by eschewing 'extern inline' functions.
10598 The trivial performance wins aren't worth the portability hassles; see
10599 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
10601 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
10602 (window_box_width, window_box_left, window_box_left_offset)
10603 (window_box_right, window_box_right_offset): Undo previous change,
10604 by removing the "extern"s.
10605 * intervals.c (adjust_intervals_for_insertion)
10606 (adjust_intervals_for_deletion): Undo previous change,
10607 making these static again.
10608 (offset_intervals, temp_set_point_both, temp_set_point)
10609 (copy_intervals_to_string): No longer inline.
10610 * xdisp.c (window_text_bottom_y, window_box_width)

10650 This is also needed for porting to any host where GC_MARK_STACK is
10651 not GC_MAKE_GCPROS_NOOPS.
10652 (which_symbols): Use it.

10667 * xmenu.c (cleanup_widget_value_tree): New function.
10668 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
10669 calling free_menubar_widget_value_tree directly (Bug#9830).

10675 (window_box_width, window_box_left, window_box_left_offset)
10676 (window_box_right, window_box_right_offset): Declare extern.
10677 Otherwise, these inline functions do not conform to C99 and
10678 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
10679 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
10680 * intervals.c (adjust_intervals_for_insertion)
10681 (adjust_intervals_for_deletion): Now extern, because otherwise the
10682 extern inline functions 'offset_intervals' couldn't refer to it.
10683 (static_offset_intervals): Remove.
10684 (offset_intervals): Rewrite using the old contents of
10685 static_offset_intervals. The old version didn't conform to C99
10686 because an extern inline function contained a reference to an
10687 identifier with static linkage.

10739 * nsfns.m: Declare image_cache_refcount if GLYPH_DEBUG.
10740 (unwind_create_frame): New function (Bug#9943).
10741 (Fx_create_frame): Restructure code to be more similar to the one in
10742 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).

10753 official. Move initialization of image_cache_refcount and
10754 dpyinfo_refcount before calling init_frame_faces (Bug#9943).

10791 2011-11-04 Eli Zaretskii <eliz@gnu.org>
10793 * xdisp.c (note_mouse_highlight): If either of
10794 previous/next-single-property-change returns nil, treat that as
10795 the beginning or the end of the buffer. (Bug#9955)
10797 2011-11-04 Jan Djärv <jan.h.d@swipnet.se>
10799 * gtkutil.c (xg_make_tool_item): Add callbacks if one of wimage or
10800 label is not null (Bug#9951).

10819 * xdisp.c (mouse_face_from_buffer_pos): Fix a typo in a comment.
10820 Don't stop backward scan on the continuation glyph, even though
10821 its CHARPOS is positive.
10822 (mouse_face_from_buffer_pos, note_mouse_highlight):
10823 Rename cover_string to disp_string.

10833 * xdisp.c (try_cursor_movement): Make sure ROW isn't decremented
10834 past the beginning of the current glyph matrix.
10836 2011-10-30 Adam Sjøgren <asjo@koldfront.dk> (tiny change)
10838 * xterm.c: Include X11/Xproto.h if HAVE_GTK3.
10839 (x_error_handler): Ignore BadMatch for X_SetInputFocus for

10882 2011-10-29 Glenn Morris <rgm@gnu.org>
10884 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
10885 Not clear what it was for, and it causes various bugs. (Bug#9839)
10887 2011-10-28 Eli Zaretskii <eliz@gnu.org>
10889 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
10890 possible random value that matches one of those tested as
10891 condition to clear the mouse face.
10893 2011-10-28 Chong Yidong <cyd@gnu.org>

10905 2011-10-28 Juanma Barranquero <lekktu@gmail.com>

10909 2011-10-28 Eli Zaretskii <eliz@gnu.org>
10911 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
10912 <oslsachem@gmail.com> for helping to debug this.
10914 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)

10920 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
10922 (w32font_open_internal, compute_metrics):
10923 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
10924 instead of calling the "wide" APIs directly.
10926 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
10928 * w32.h (syms_of_w32font): Add prototype.
10930 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
10932 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
10933 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
10934 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
10935 (Fmove_to_window_line): Doc fix.
10937 2011-10-27 Chong Yidong <cyd@gnu.org>
10939 * process.c (make_process): Set gnutls_state to NULL.
10941 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
10942 non-NULL, regardless of GNUTLS_INITSTAGE.
10943 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
10944 an error. Set process slots as soon as we allocate them.
10946 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
10948 2011-10-27 Chong Yidong <cyd@gnu.org>
10950 * gnutls.c (emacs_gnutls_deinit): New function.

10955 (deactivate_process): Call emacs_gnutls_deinit.
10957 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
10959 * image.c (x_create_x_image_and_pixmap):
10960 * w32.c (sys_rename, w32_delayed_load):
10961 * w32font.c (fill_in_logfont):

10967 extracted from Fw32_default_color_map.
10968 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
10970 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
10972 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
10974 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
10976 * keyboard.c (test_undefined): New function (bug#9751).
10977 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
10979 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
10981 * sysdep.c (init_sys_modes): Fix the check for the controlling
10982 terminal (Bug#6649).
10984 2011-10-20 Eli Zaretskii <eliz@gnu.org>
10986 * dispextern.h (struct bidi_it): New member next_en_type.
10988 * bidi.c (bidi_line_init): Initialize the next_en_type member.
10989 (bidi_resolve_explicit_1): When next_en_pos is valid for the
10990 current character, check also for next_en_type being WEAK_EN.
10991 (bidi_resolve_weak): Don't enter the expensive loop if the current
10992 position is before next_en_pos. Record the bidi type of the first
10993 non-ET, non-BN character we find, in addition to its position.
10994 (bidi_level_of_next_char): Invalidate next_en_type when
10995 next_en_pos is over-stepped.
10997 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
10999 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
11000 * editfns.c: Rewrite current-time-zone so that it invokes
11001 the equivalent of (format-time-string "%Z") to get the time zone name.
11002 This fixes a bug when the time zone name contains characters that
11003 need converting from the system time locale to Emacs internal format.
11004 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
11005 that patch fixed format-time-string to do the conversion, but
11006 I forgot to fix current-time-zone.
11007 (format_time_string): New function, containing most of
11008 what Fformat_time_string used to contain.
11009 (Fformat_time_string): Rewrite in terms of format_time_string.
11010 This doesn't change this function's behavior.
11011 (current-time-zone): Rewrite to use format_time_string.
11012 This fixes the bug reported by Michael Schierl in
11013 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
11014 Jason Rumney's 2007-06-07 change worked around this bug, but
11016 * systime.h (tzname, timezone): Remove no-longer-used declarations.
11018 2011-10-19 Eli Zaretskii <eliz@gnu.org>
11020 * xdisp.c (start_display): If the character at POS is displayed
11021 via a display vector, reset IT->current.dpvec_index to zero.
11022 (try_window_reusing_current_matrix): If a line ends in a display
11023 vector or the next line starts in a display vector, continue
11024 redrawing the window even though the character position of
11025 start_row was reached.
11028 2011-10-18 Chong Yidong <cyd@gnu.org>
11030 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
11031 with nobreak-char-display too.
11033 2011-10-18 Eli Zaretskii <eliz@gnu.org>
11035 Fix part 3 of bug#9771.
11036 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
11037 (bidi_resolve_neutral): Don't enter the expensive loop looking for
11038 non-neutral characters if the current character is a paragraph
11039 separator (a.k.a. Newline). This avoids running the same
11040 expensive loop twice, once when we consume the preceding newline
11041 and the other time when the line actually needs to be displayed.
11042 Avoid the loop when we see neutrals on the base embedding level
11043 following a character whose directionality is the same as the
11044 paragraph's. This avoids running the expensive loop when a line
11045 ends in a long sequence of neutrals, like control characters.
11046 Add assertion against STRONG_AL type. Slightly rearrange code
11047 that determines the type of a neutral given the first non-neutral
11049 (bidi_level_of_next_char): Set next_en_pos to zero when
11050 invalidating its info.
11052 2011-10-17 Eli Zaretskii <eliz@gnu.org>
11054 * xdisp.c (push_display_prop): Determine whether to record string
11055 or buffer position by IT->string, not by IT->method. Allow
11056 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
11057 (move_it_vertically_backward): Don't look for character position
11058 immediately after the newline when in a continuation line.
11061 2011-10-15 Martin Rudalics <rudalics@gmx.at>
11063 * window.c (coordinates_in_window): Rewrite and delabelize
11064 vertical border check. (Bug#5357) (Bug#9618)
11066 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
11068 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
11069 errors in XSetWindowBorder (bug#9310).
11071 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
11073 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
11074 avoid crash when xmalloc overrun checking is enabled.
11076 2011-10-13 Eli Zaretskii <eliz@gnu.org>
11078 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
11079 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
11080 cursor motion with <left> and <right> arrow keys.
11082 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
11083 some callers set that themselves.
11085 2011-10-12 Eli Zaretskii <eliz@gnu.org>
11087 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
11088 display string and the previous row comes from the same string and
11089 is empty. (Bug#9739) (Bug#9738)
11091 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
11093 * doc.c (get_doc_string): Encode file name (bug#9735).
11095 2011-10-12 Eli Zaretskii <eliz@gnu.org>
11097 * bidi.c (bidi_level_of_next_char):
11098 * xdisp.c (get_visually_first_element): Remove old incorrect
11099 comments regarding the Unicode Line Separator character.
11101 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
11103 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
11105 * alloc.c (Fgc_status): Do not access beyond zombies array
11106 boundary if nzombies > MAX_ZOMBIES.
11107 * alloc.c (dump_zombies): Add missing format specifier.
11109 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
11111 * xdisp.c (set_cursor_from_row): Simplify conditionals,
11112 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
11114 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
11115 Some packages use them to denote characters with modifiers.
11117 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
11119 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
11120 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
11121 matching a pp-number. Rename parameter var to var1.
11123 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
11125 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
11127 2011-10-08 Glenn Morris <rgm@gnu.org>
11129 * callint.c (Fcall_interactively): Give a more explicit error for the
11130 'c' case with a non-character input. (Bug#8479)
11132 2011-10-08 Eli Zaretskii <eliz@gnu.org>
11134 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
11136 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
11137 lines that are hscrolled on the left.
11139 * dispnew.c (buffer_posn_from_coords): Account for a possible
11140 presence of header-line. (Bug#4426)
11142 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
11144 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
11145 Don't advertise functionality which we discourage or doesn't work.
11147 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
11149 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
11150 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
11151 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
11152 this makes Emacs dump core during garbage collection on rare
11153 occasions. sizeof is obviously inferior to offsetof here, so
11154 stick with offsetof.
11155 (GC_POINTER_ALIGNMENT): New macro.
11156 (mark_memory): Omit 3rd (offset) arg; caller changed.
11157 Don't assume EMACS_INT alignment is the same as pointer alignment.
11159 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
11161 * keyboard.c (read_key_sequence_remapped): New var.
11162 (read_key_sequence): Compute remapping in the right buffer.
11163 (command_loop_1): Use read_key_sequence's remapping directly.
11165 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
11167 * dired.c (file_name_completion): Don't expand file name.
11168 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
11169 before checking file name handler.
11171 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
11172 they've been requested explicitly (bug#9591).
11174 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
11176 * keymap.c (Fsingle_key_description): Use make_specified_string
11177 instead of build_string to build string from push_key_description.
11180 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
11182 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
11183 This fixes a Y2038 bug on 64-bit hosts.
11184 * buffer.c (reset_buffer):
11185 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
11186 (Fclear_buffer_auto_save_failure):
11187 Use 0, not -1, to represent an unset failure time, since time_t
11188 might not be signed.
11190 Remove dependency on glibc malloc internals.
11191 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11192 Move back here from lisp.h, but with their new implementations.
11193 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
11194 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
11195 * charset.c (charset_table_init): New static var.
11196 (syms_of_charset): Use it instead of xmalloc. This removes a
11197 dependency on glibc malloc internals. See Eli Zaretskii's comment in
11198 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
11199 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11200 Move back to alloc.c.
11201 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
11202 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
11204 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
11206 * nsterm.m (windowDidResize): Call x_set_window_size only when
11207 ns_in_resize is true. Otherwise set pixelwidth/height and
11208 call change_frame_size (Bug#9628).
11210 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
11212 Port --enable-checking=all to Fedora 14 x86-64.
11213 * charset.c (syms_of_charset): Also account for glibc malloc's
11214 internal overhead when calculating the initial malloc maximum.
11216 Port --enable-checking=all to Fedora 14 x86.
11217 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11219 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
11220 (overrun_check_realloc, overrun_check_free):
11221 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
11222 That way, xmalloc returns a properly-aligned pointer even if
11223 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
11224 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
11225 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
11226 into account when calculating the initial malloc maximum.
11227 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11228 Move here from alloc.c, so that charset.c can use it too.
11229 Properly align; the old code wasn't right for common 32-bit hosts
11230 when configured with --enable-checking=all.
11231 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
11232 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
11234 2011-09-29 Eli Zaretskii <eliz@gnu.org>
11236 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
11239 2011-09-28 Eli Zaretskii <eliz@gnu.org>
11241 * xdisp.c (compute_display_string_end): If there's no display
11242 string at CHARPOS, return -1.
11244 * bidi.c (bidi_fetch_char): When compute_display_string_end
11245 returns a negative value, treat the character as a normal
11246 character not covered by a display string. (Bug#9624)
11248 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
11250 * lread.c (Fread_from_string): Fix typo in docstring.
11252 2011-09-27 Eli Zaretskii <eliz@gnu.org>
11254 * xdisp.c (handle_invisible_prop): If invisible text ends on a
11255 newline, reseat the iterator instead of bidi-iterating there one
11256 character at a time. (Bug#9610)
11257 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
11258 TO_CHARPOS if the bidi iterator is at base embedding level.
11260 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
11262 * lread.c (readevalloop): Use correct code for NBSP.
11263 (read1): Likewise. (Bug#9608)
11265 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
11267 * dbusbind.c (Fdbus_register_signal): When service is not
11268 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
11270 2011-09-25 Glenn Morris <rgm@gnu.org>
11272 * buffer.c (truncate-lines): Doc fix.
11274 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
11276 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
11277 (Fset_window_next_buffers): Doc fix.
11279 2011-09-24 Glenn Morris <rgm@gnu.org>
11281 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
11283 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
11285 Fix minor problems found by static checking.
11286 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
11287 * indent.c (Fvertical_motion): Fix == vs = typo.
11289 2011-09-24 Eli Zaretskii <eliz@gnu.org>
11291 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
11292 Default value is now t. Doc fix.
11294 * indent.c (Fvertical_motion): Compute and apply the overshoot
11295 logic when moving up, not only when moving down. Fix the
11296 confusing name and values of the it_overshoot_expected variable;
11297 logic changes accordingly. (Bug#9254) (Bug#9549)
11299 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
11300 CHARPOS is covered by a display string which includes newlines.
11301 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
11302 is covered by a display string with embedded newlines.
11304 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
11306 * dbusbind.c (Fdbus_register_signal): Add match rule to
11307 Vdbus_registered_objects_table. (Bug#9581)
11308 (Fdbus_register_method, Vdbus_registered_objects_table):
11311 2011-09-24 Jim Meyering <meyering@redhat.com>
11313 do not ignore write error for any output size
11314 The previous change was incomplete.
11315 While it makes emacs --batch detect the vast majority of stdout
11316 write failures, errors were still ignored whenever the output size is
11317 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
11318 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
11319 && echo FAIL: ignored write error
11320 FAIL: ignored write error
11321 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
11322 && echo FAIL: ignored write error
11323 FAIL: ignored write error
11324 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
11326 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
11328 * emacs.c (Fkill_emacs): In noninteractive mode exit
11329 non-successfully if a write error occurred on stdout. (Bug#9574)
11331 2011-09-21 Eli Zaretskii <eliz@gnu.org>
11333 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
11336 * dispextern.h (struct it): Update the comment documenting what
11339 2011-09-20 Eli Zaretskii <eliz@gnu.org>
11341 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
11342 a display string, extend search for cursor position to end of row.
11343 (find_row_edges): If the row ends in a newline from a display
11344 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
11345 Handle the case of a display string with multiple newlines.
11346 (Fcurrent_bidi_paragraph_direction): Fix search for previous
11347 non-empty line. Fixes confusing cursor motion with arrow keys at
11348 the beginning of a line that starts with whitespace.
11350 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
11352 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
11355 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
11357 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
11358 boolean (Bug#9154).
11360 2011-09-18 Eli Zaretskii <eliz@gnu.org>
11362 * xdisp.c (display_line): Record maximum and minimum buffer
11363 positions even if no glyphs were produced (e.g., by a zero-width
11364 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
11365 buffer positions that will be removed from the glyph row because
11367 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
11368 column is beyond frame width: don't subtract 1 "pixel" when
11369 computing width of the stretch.
11370 (reseat_at_next_visible_line_start): Undo the change made on
11371 2011-09-17 that saved paragraph information and restored it after
11372 the call to `reseat'. (Bug#9545)
11374 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11376 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
11377 and turn window cursor on if cleared (Bug#9415).
11379 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
11381 * search.c (boyer_moore): Take unibyte characters from pattern
11382 literally. (Bug#9458)
11384 2011-09-18 Eli Zaretskii <eliz@gnu.org>
11386 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
11388 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
11390 Fix minor problem found by static checking.
11391 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
11392 initialized, to pacify gcc -Wuninitialized.
11394 * fileio.c: Report proper errno when syscall falls.
11395 (Finsert_file_contents): Save and restore errno,
11396 so that report_file_error outputs the correct diagnostic.
11397 (Fwrite_region) [CLASH_DETECTION]: Likewise.
11399 2011-09-18 Eli Zaretskii <eliz@gnu.org>
11401 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
11403 2011-09-17 Eli Zaretskii <eliz@gnu.org>
11405 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
11406 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
11408 2011-09-17 Eli Zaretskii <eliz@gnu.org>
11410 * xdisp.c (reseat_at_next_visible_line_start): Keep information
11411 about the current paragraph and restore it after the call to reseat.
11413 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
11414 (bidi_find_paragraph_start): Search back for paragraph beginning
11415 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
11416 (bidi_move_to_visually_next): Only trigger paragraph-related
11417 computations when the last character is a newline or at EOB, not
11418 just any NEUTRAL_B. (Bug#9470)
11420 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
11421 truncated lines if point is covered by a display string. (Bug#9524)
11423 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
11425 * xselect.c: Relax test for outgoing X longs (Bug#9498).
11426 (cons_to_x_long): New function.
11427 (lisp_data_to_selection_data): Use it. Correct the test for
11428 short-versus-long data; it was negated. Break out of vector
11429 loop, for efficiency, when a long datum is discovered.
11431 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
11433 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
11435 2011-09-16 Eli Zaretskii <eliz@gnu.org>
11437 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
11438 GCC PR/17406) by declaring this function with external scope.
11440 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
11442 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
11443 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
11445 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
11447 * editfns.c (Fformat): Correctly handle text properties on "%%".

11455 * xdisp.c (get_next_display_element)
11456 (fill_composite_glyph_string): Add comments about special meaning
11457 of TAB characters in a composition.
11459 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
11461 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
11462 This occurs when processing a multibyte format.
11463 Problem reported by Wolfgang Jenker.
11465 2011-09-15 Johan Bockgård <bojohan@gnu.org>
11467 * xdisp.c (try_cursor_movement): Only check for exact match if
11468 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
11470 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
11472 Remove unused external symbols.
11473 * dispextern.h (calc_pixel_width_or_height): Remove decl.
11474 * xdisp.c (calc_pixel_width_or_height): Now static.
11475 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
11476 * indent.c (check_display_width):
11477 * w32term.c: Fix comment to match code.
11478 * xterm.c, xterm.h (x_catching_errors): Remove.
11480 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
11482 * xselect.c: Use signed conversions more consistently (Bug#9498).
11483 (selection_data_to_lisp_data): Assume incoming selection data are
11484 signed integers, not unsigned. This is to be consistent with
11485 outgoing selection data, which was modified to use signed integers
11486 in as part of the fix to Bug#9196 in response to Jan D.'s comment
11487 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
11488 expects long, not unsigned long.
11490 2011-09-14 Eli Zaretskii <eliz@gnu.org>
11492 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
11493 computation of loop end. Reported by Johan Bockgård
11496 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
11498 * frame.c (Fother_visible_frames_p): Function deleted.
11500 2011-09-12 Eli Zaretskii <eliz@gnu.org>
11502 * indent.c (compute_motion): Process display vector front to back
11503 rather than the other way around. (Bug#2496)
11505 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
11507 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
11509 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
11511 * minibuf.c (Fread_from_minibuffer): Doc fix.
11513 2011-09-11 Eli Zaretskii <eliz@gnu.org>
11515 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
11516 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
11518 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
11520 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
11521 value for non-existent files.
11523 2011-09-11 Eli Zaretskii <eliz@gnu.org>
11525 * fileio.c (Finsert_file_contents): If the file cannot be opened,
11526 set its "size" to -1. This will set the modtime_size field of
11527 the corresponding buffer to -1, which is what
11528 verify-visited-file-modtime expects for files that do not exist.
11531 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
11533 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
11535 * lisp.h: ... from here. push_key_description is no longer
11536 defined in keyboard.c, so its declaration should not be in
11537 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
11538 logically belongs with push_key_description.
11540 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
11542 * buffer.h: Include <sys/types.h> instead of <time.h>.
11543 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
11544 Problem reported by Herbert J. Skuhra.
11546 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
11548 * xml.c (parse_region): Make the parsing work for
11549 non-comment-starting XML files again (bug#9144).
11551 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
11553 * image.c (gif_load): Fix calculation of bottom and right corner.
11556 2011-09-10 Eli Zaretskii <eliz@gnu.org>
11558 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
11559 redisplay in small windows.
11561 2011-09-09 Eli Zaretskii <eliz@gnu.org>
11563 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
11565 2011-09-08 Martin Rudalics <rudalics@gmx.at>
11567 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
11568 Operate on live windows only.
11570 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
11572 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
11574 2011-09-07 Eli Zaretskii <eliz@gnu.org>
11576 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
11577 only under bidi iteration.
11579 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
11581 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
11583 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
11585 isnan: Fix porting problem to Solaris 10 with bundled gcc.
11586 Without this fix, the command to link temacs failed due to an
11587 undefined symbol __builtin_isnan. This is because
11588 /usr/include/iso/math_c99.h #defines isnan(x) to
11589 __builtin_isnan(x), but the bundled gcc, which identifies itself
11590 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
11592 * floatfns.c (isnan): #undef, and then #define to a clone of
11594 (Fisnan): Always define, since it's always available now.
11595 (syms_of_floatfns): Always define isnan at the Lisp level.
11597 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
11599 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
11601 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
11603 * fileio.c: Fix bugs with large file offsets (Bug#9428).
11604 The previous code assumed that file offsets (off_t values) fit in
11605 EMACS_INT variables, which is not true on typical 32-bit hosts.
11606 The code messed up by falsely reporting buffer overflow in cases
11607 such as (insert-file-contents "big" nil 1 2) into an empty buffer
11608 when "big" contains more than 2**29 bytes, even though this
11609 inserts just one byte and does not overflow the buffer.
11610 (Finsert_file_contents): Store file offsets as off_t
11611 values, not as EMACS_INT values. Check for overflow when
11612 converting between EMACS_INT and off_t. When checking for
11613 buffer overflow or for overlap, take the offsets into account.
11614 Don't use EMACS_INT for small values where int suffices.
11615 When checking for overlap, fix a typo: ZV was used where
11616 ZV_BYTE was intended.
11617 (Fwrite_region): Don't assume off_t fits into 'long'.
11618 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
11620 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
11622 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
11624 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
11626 sprintf-related integer and memory overflow issues (Bug#9412).
11628 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
11629 (esprintf, exprintf, evxprintf): New functions.
11630 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
11631 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
11632 (modify_event_symbol): Do not assume that the length of
11633 name_alist_or_stem is safe to alloca and fits in int.
11634 (Fexecute_extended_command): Likewise for function name and binding.
11635 (Frecursion_depth): Wrap around reliably on integer overflow.
11636 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
11637 since some callers pass EMACS_INT values.
11638 (Fsingle_key_description): Don't crash if symbol name contains more
11639 than MAX_ALLOCA bytes.
11640 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
11641 (get_minibuffer): Arg is now EMACS_INT, not int.
11642 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
11643 (esprintf, exprintf, evxprintf): New decls.
11644 * window.h (command_loop_level, minibuf_level): Reflect API changes.
11646 * dbusbind.c (signature_cat): New function.
11647 (xd_signature, Fdbus_register_signal):
11648 Do not overrun buffer; instead, report string overflow.
11650 * dispnew.c (add_window_display_history): Don't overrun buffer.
11651 Truncate instead; this is OK since it's just a log.
11653 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
11654 even if the time zone offset is outlandishly large.
11655 Don't mishandle offset == INT_MIN.
11657 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
11658 when creating daemon; the previous buffer-overflow check was incorrect.
11660 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
11661 which has the guts of the old verror function.
11663 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
11664 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
11666 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
11667 (font_unparse_xlfd): Don't blindly alloca long strings.
11668 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
11669 fits in int, when using sprintf. Use single snprintf to count
11670 length of string rather than counting it via multiple sprintfs;
11671 that's simpler and more reliable.
11672 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
11673 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
11674 sprintf, in case result does not fit in int.
11676 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
11677 (fontset_from_font): Print it.
11679 * frame.c (tty_frame_count): Now printmax_t, not int.
11680 (make_terminal_frame, set_term_frame_name): Print it.
11681 (x_report_frame_params): In X, window IDs are unsigned long,
11682 not signed long, so print them as unsigned.
11683 (validate_x_resource_name): Check for implausibly long names,
11684 and don't assume name length fits in 'int'.
11685 (x_get_resource_string): Don't blindly alloca invocation name;
11686 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
11689 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
11690 (xg_check_special_colors, xg_set_geometry):
11691 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
11693 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
11694 Use esprintf, not sprintf, in case result does not fit in int.
11696 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
11697 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
11698 it as a large positive number.
11699 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
11700 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
11702 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
11703 in case result does not fit in int.
11705 * print.c (float_to_string): Detect width overflow more reliably.
11706 (print_object): Make sprintf buffer a bit bigger, to avoid potential
11707 buffer overrun. Don't assume list length fits in 'int'. Treat
11708 print length of 0 as 0, not as infinity; to be consistent with other
11709 uses of print length in this function. Don't overflow print length
11710 index. Don't assume hash table size fits in 'long', or that
11711 vectorlike size fits in 'unsigned long'.
11713 * process.c (make_process): Use printmax_t, not int, to format
11714 process-name gensyms.
11716 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
11718 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
11719 to avoid potential buffer overrun.
11721 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
11722 if X resource line is longer than 512 bytes.
11724 * xfns.c (x_window): Make sprintf buffer a bit bigger
11725 to avoid potential buffer overrun.
11727 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
11729 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
11731 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
11733 Integer overflow fixes for scrolling, etc.
11734 Without these, Emacs silently mishandles large integers sometimes.
11735 For example, "C-u 4294967297 M-x recenter" was treated as if
11736 it were "C-u 1 M-x recenter" on a typical 64-bit host.
11738 * xdisp.c (try_window_id): Check Emacs fixnum range before
11739 converting to 'int'.
11741 * window.c (window_scroll_line_based, Frecenter):
11742 Check that an Emacs fixnum is in range before assigning it to 'int'.
11743 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
11744 values converted from Emacs fixnums.
11745 (Frecenter): Don't wrap around a line count if it is out of 'int'
11746 range; instead, treat it as an extreme value.
11747 (Fset_window_configuration, compare_window_configurations):
11748 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
11750 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
11751 that can exceed INT_MAX. Check that EMACS_INT value is in range
11752 before assigning it to the (possibly-narrower) index.
11753 (match_limit): Don't assume that a fixnum can fit in 'int'.
11755 * print.c (print_object): Use ptrdiff_t, not int, for index that can
11758 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
11759 (Fvertical_motion): Don't wrap around LINES values that don't fit
11760 in 'int'. Instead, treat them as extreme values. This is good
11761 enough for windows, which can't have more than INT_MAX lines anyway.
11763 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
11765 * Require libxml/parser.h to avoid compilation warning.
11767 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
11769 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
11770 since this reportedly can destroy thread storage.
11772 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
11774 * syntax.c (find_defun_start): Update all cache variables if
11775 exiting early (Bug#9401).
11777 2011-08-30 Eli Zaretskii <eliz@gnu.org>
11779 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
11781 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
11782 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
11783 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
11785 * term.c (tty_append_glyph): New function.
11786 (produce_stretch_glyph): Static function and its prototype deleted.
11788 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
11791 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
11793 * image.c (parse_image_spec): Check for nonnegative, not for positive,
11794 when checking :margin (Bug#9390).
11795 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
11796 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
11797 so that the name doesn't mislead. All uses changed.
11799 2011-08-28 Johan Bockgård <bojohan@gnu.org>
11801 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
11804 2011-08-27 Eli Zaretskii <eliz@gnu.org>
11806 * xdisp.c (move_it_to): Don't bail out early when reaching
11807 position beyond to_charpos, if we are scanning backwards.
11808 (move_it_vertically_backward): When DY == 0, make sure we get to
11809 the first character in the line after the newline.
11811 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
11813 * ccl.c: Improve and simplify overflow checking (Bug#9196).
11814 (ccl_driver): Do not generate an out-of-range pointer.
11815 (Fccl_execute_on_string): Remove unnecessary check for
11816 integer overflow, noted by Stefan Monnier in
11817 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
11818 Remove a FIXME that didn't need fixing.
11819 Simplify the newly-introduced buffer reallocation code.
11821 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
11823 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
11825 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
11827 Integer and memory overflow issues (Bug#9196).
11829 * doc.c (get_doc_string): Rework so that
11830 get_doc_string_buffer_size is the actual buffer size, rather than
11831 being 1 less than the actual buffer size; this makes xpalloc more
11834 * image.c (x_allocate_bitmap_record, cache_image):
11835 * xselect.c (Fx_register_dnd_atom):
11836 Simplify previous changes by using xpalloc.
11838 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
11839 since either will do and ptrdiff_t is convenient with xpalloc.
11841 * charset.c (charset_table_size)
11842 (struct charset_sort_data.priority): Now ptrdiff_t.
11843 (charset_compare): Don't overflow if priorities differ greatly.
11844 (Fsort_charsets): Don't assume list length fits in int.
11845 Check for size-calculation overflow when allocating sort data.
11846 (syms_of_charset): Allocate an initial charset table that is
11847 just under 64 KiB, to avoid problems with glibc malloc and mmap.
11849 * cmds.c (internal_self_insert): Check for size-calculation overflow.
11851 * composite.h (struct composition.glyph_len): Now int, not unsigned.
11852 The actual value is always <= INT_MAX, and leaving it unsigned made
11853 overflow checking harder.
11855 * dispextern.h (struct glyph_matrix.rows_allocated)
11856 (struct face_cache.size): Now ptrdiff_t, for convenience in use
11857 with xpalloc. The values are still always <= INT_MAX.
11859 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
11861 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
11862 (SAFE_NALLOCA): New macro.
11864 * region-cache.c (struct boundary.pos, find_cache_boundary)
11865 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
11866 (set_cache_region, invalidate_region_cache)
11867 (revalidate_region_cache, know_region_cache, region_cache_forward)
11868 (region_cache_backward, pp_cache):
11869 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
11870 so that ptrdiff_t * can be passed to xpalloc.
11871 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
11872 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
11873 (pp_cache): Don't assume cache_len fits in int.
11874 * region-cache.h: Adjust extern decls to match.
11876 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
11877 EMACS_INT, since either will do, for xpalloc.
11879 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
11880 (xnmalloc, xnrealloc, xpalloc): New functions.
11882 * bidi.c (bidi_shelve_header_size): New constant.
11883 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
11884 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
11886 * bidi.c (bidi_cache_shrink):
11887 * buffer.c (overlays_at, overlays_in, record_overlay_string)
11889 Don't update size of array until after memory allocation succeeds,
11890 because xmalloc/xrealloc may not return.
11891 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
11892 now that we have proper integer overflow checking.
11893 (record_overlay_string, overlay_strings): Catch overflows when
11894 calculating size of overlay_str_buf.
11896 * callproc.c (Fcall_process): Check for size overflow when
11897 calculating size of args2.
11898 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
11899 Normally we prefer signed values, but sticking with ptrdiff_t would
11900 require adding more-complicated checks.
11902 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
11903 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
11904 Redo buffer-overflow calculations to avoid integer overflow.
11905 Add a FIXME comment where memory seems to be over-allocated.
11907 * character.c (Fstring): Check for size-calculation overflow.
11909 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
11910 unnecessary integer overflow. Check for size overflow.
11911 (encode_coding_object): Don't update size until xmalloc succeeds.
11913 * composite.c (get_composition_id): Check for overflow in glyph
11914 length calculations.
11916 Integer and memory overflow fixes for display code.
11917 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
11918 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
11919 (scrolling_window): Check for overflow in size calculations.

11931 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
11932 (get_doc_string): Check for size calculation overflow.
11933 Don't update size until allocation succeeds.
11934 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
11935 EMACS_INT, where ptrdiff_t will do.
11936 (Fsubstitute_command_keys): Check for string overflow.
11938 * editfns.c (set_time_zone_rule): Don't assume environment length
11940 (message_length): Now ptrdiff_t, not int.
11941 (Fmessage_box): Don't update size until allocation succeeds.
11942 Don't assume message length fits in int.
11943 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
11945 * emacs.c (main): Do not reallocate argv, since there is a null at
11946 the end that can be overwritten, and this way there's no need to
11947 worry about size-calculation overflow.
11948 (sort_args): Check for size-calculation overflow.
11950 * eval.c (init_eval_once, grow_specpdl): Don't update size until
11952 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
11954 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
11955 (x_set_scroll_bar_width, x_figure_window_size):
11956 Check for integer overflow.
11957 (x_set_alpha): Do not assume XINT fits in int.
11959 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
11960 This is for the members text_lines, text_cols, total_lines, total_cols,
11961 where the system imposes an 'int' limit.
11963 * fringe.c (Fdefine_fringe_bitmap):
11964 Don't update size until alloc works.
11966 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
11967 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
11969 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
11970 Check for size-calculation overflow.
11971 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
11972 do, as we prefer signed integers.
11973 (id_to_widget.max_size, id_to_widget.used)
11974 (xg_store_widget_in_map, xg_remove_widget_from_map)
11975 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
11976 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
11977 Use and return ptrdiff_t, not int.
11978 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
11979 * gtkutil.h: Change prototypes to match the above.
11981 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
11982 are duplicate now that they've been promoted to lisp.h.
11983 (x_allocate_bitmap_record, x_alloc_image_color)
11984 (make_image_cache, cache_image, xpm_load):
11985 Don't update size until alloc is done.

11995 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
11996 Use ptrdiff_t, not int, to count maps.

11998 calculations. Don't update size until allocation succeeds.
11999 Redo calculations to avoid overflow.
12000 * keyboard.h: Change prototypes to match the above.
12002 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
12004 (current_minor_maps): Check for size calculation overflow.
12005 * keymap.h: Change prototypes to match the above.
12007 * lread.c (read1, init_obarray): Don't update size until alloc done.
12009 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.

12028 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
12029 for command line length. Do not attempt to address one before the
12030 beginning of an array, as that's not portable.
12032 * term.c (max_frame_lines): Remove; unused.
12033 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
12035 (encode_terminal_code, calculate_costs): Check for size
12036 calculation overflow.

12058 Use ptrdiff_t, not int, for sizes.
12059 (Finternal_make_lisp_face, cache_face):
12060 Check for size calculation overflow.
12061 (cache_face): Treat size calculation overflows as if they were
12062 memory exhaustion (the usual treatment), rather than aborting.
12064 * xfns.c (x_encode_text, x_set_name_internal)
12065 (Fx_change_window_property): Use ptrdiff_t, not int, to count
12066 sizes, since they can exceed INT_MAX in size. Check for size
12067 calculation overflow.
12069 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
12070 (xg_select): Check for size calculation overflow.
12071 Don't update size until alloc done.
12073 * xrdb.c (get_environ_db): Don't assume path length fits in int,
12074 as sprintf is limited to int lengths.
12076 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
12077 (X_LONG_MIN): New macros.
12078 Use them to make the following changes clearer.
12079 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
12080 This change doesn't affect the value now, but it may help remind
12081 future maintainers not to raise the value too much later.
12082 (SELECTION_QUANTUM): Remove, replacing with ...
12083 (selection_quantum): ... new function, which avoids overflow.
12085 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
12086 assumption that selection length fits in 'int'.
12087 (x_reply_selection_request, x_handle_selection_request)
12088 (x_get_window_property, receive_incremental_selection)

12092 (x_reply_selection_request, x_get_window_property)
12093 (receive_incremental_selection, x_property_data_to_lisp):
12094 Redo calculations to avoid overflow.
12095 (x_reply_selection_request): When sending hint, ceiling it at
12096 X_LONG_MAX rather than relying on wraparound overflow to send
12098 (x_get_window_property, receive_incremental_selection)
12099 (lisp_data_to_selection_data, x_property_data_to_lisp):
12100 Check for size-calculation overflow.
12101 (x_get_window_property, receive_incremental_selection)

12103 Don't store size until memory allocation succeeds.
12104 (x_get_window_property): Plug memory leak on memory exhaustion.
12105 Don't double-block input; malloc is safe here. Don't assume 2**34
12106 - 4 fits in unsigned long. Add an xassert to check
12107 XGetWindowProperty overflow. Be more careful about overflow
12108 calculations, and distinguish size from memory overflow better.
12109 (receive_incremental_selection): When tracing, don't assume
12110 unsigned int is less than INT_MAX.
12111 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
12112 harmful) conversions of unsigned short to int.
12113 (lisp_data_to_selection_data): Don't assume that integers
12114 in the range -65535 through -1 fit in an X unsigned short.
12115 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
12116 result parameters unless successful. Rely on cons_to_unsigned
12117 to report problems with elements; the old code wasn't right anyway.
12118 (x_check_property_data): Check for int overflow; we cannot use
12119 a wider type due to X limits.
12120 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
12122 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.
12124 * xterm.c (x_color_cells, x_send_scrollbar_event, handle_one_xevent)
12125 (x_term_init): Check for size calculation overflow.
12126 (x_color_cells): Don't store size until memory allocation succeeds.
12127 (handle_one_xevent): Use ptrdiff_t, not int, for byte counts.
12128 Don't assume alloca size is less than MAX_ALLOCA.
12129 (x_term_init): Don't assume length fits in int (sprintf is limited
12132 Use ptrdiff_t for composition IDs.
12133 * character.c (lisp_string_width):
12134 * composite.c (composition_table_size, n_compositions)
12135 (get_composition_id, composition_gstring_from_id):

12151 * image.c (xpm_get_color_table_h):
12152 * lisp.h (hash_lookup, hash_put):
12153 * minibuf.c (Ftest_completion):
12154 Use ptrdiff_t for hash table indexes, not int (which is too
12155 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
12156 32-bit --with-wide-int hosts).
12158 * charset.c (Fdefine_charset_internal): Check for integer overflow.
12159 Add a FIXME comment about memory leaks.
12160 (syms_of_charset): Don't assume xmalloc returns.
12162 Don't assume that stated character widths fit in int.
12163 * character.c (Fchar_width, c_string_width, lisp_string_width):
12164 * character.h (CHAR_WIDTH):
12165 * indent.c (MULTIBYTE_BYTES_WIDTH):
12166 Use sanitize_char_width to avoid undefined and/or bad behavior
12167 with outlandish widths.
12168 * character.h (sanitize_tab_width): Rename from sanitize_width,
12169 now that we have two such functions. All uses changed.
12170 (sanitize_char_width): New inline function.
12172 Don't assume that tab-width fits in int.
12173 * character.h (sanitize_width): New inline function.
12174 (SANE_TAB_WIDTH): New macro.
12175 (ASCII_CHAR_WIDTH): Use it.
12176 * indent.c (sane_tab_width): Remove. All uses replaced by
12177 SANE_TAB_WIDTH (current_buffer).
12178 * xdisp.c (init_iterator): Use SANE_TAB_WIDTH.
12180 * fileio.c: Integer overflow issues with file modes.
12181 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
12183 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
12184 Remove unreachable code.
12185 (read_hex, load_charset_map_from_file): Check for integer overflow.
12187 * xterm.c: Don't go over XClientMessageEvent limit.
12188 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
12189 (x_send_scroll_bar_event): Likewise. Check that the size does not
12190 exceed limits imposed by XClientMessageEvent, as well as the usual
12191 ptrdiff_t and size_t limits.
12193 * keyboard.c: Overflow, signedness and related fixes.
12194 (make_lispy_movement): Use same integer type in forward decl
12195 that is used in the definition.
12196 (read_key_sequence, keyremap_step):
12197 Change bufsize argument back to int, undoing my 2011-03-30 change.
12198 We prefer signed types, and int is wide enough here.
12199 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
12200 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
12201 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
12202 length, not size_t. Use ptrdiff_t for index, not int.
12203 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
12204 possibility of integer overflow.
12206 Overflow, signedness and related fixes for images.
12208 * dispextern.h (struct it.stack[0].u.image.image_id)
12209 (struct_it.image_id, struct image.id, struct image_cache.size)

12216 * xdisp.c (calc_pixel_width_or_height):
12217 * xfns.c (image_cache_refcount):
12218 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
12219 on typical 64-bit hosts.

12227 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
12228 (lookup_image): Remove unnecessary tests.
12229 (xbm_image_p): Locals are now of int, not EMACS_INT,
12230 since parse_image_check makes sure they fit into int.
12231 (png_load, gif_load, svg_load_image):
12232 Prefer int to unsigned where either will do.
12233 (tiff_handler): New function, combining the cores of the
12234 old tiff_error_handler and tiff_warning_handler.
12235 This function is rewritten to use vsnprintf and thereby avoid
12236 stack buffer overflows. It uses only the features of vsnprintf
12237 that are common to both POSIX and native Microsoft.
12238 (tiff_error_handler, tiff_warning_handler): Use it.
12239 (tiff_load, gif_load, imagemagick_load_image):
12240 Don't assume :index value fits in 'int'.
12241 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
12242 (imagemagick_load_image): Check that crop parameters fit into
12243 the integer types that MagickCropImage accepts. Don't assume
12244 Vimagemagick_render_type has a nonnegative value. Don't assume
12245 size_t fits in 'long'.
12246 (gs_load): Use printmax_t to print the widest integers possible.
12247 Check for integer overflow when computing image height and width.
12249 2011-08-26 Eli Zaretskii <eliz@gnu.org>
12251 * xdisp.c (redisplay_window): Don't force window start if point
12252 will be invisible in the resulting window. (Bug#9324)

12256 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
12257 the display spec is of the form `(space ...)'.
12258 (handle_display_spec): Return the value returned by
12259 handle_single_display_spec, not just 1 or zero.
12260 (handle_single_display_spec): If the display spec is of the form
12261 `(space ...)', and specifies display in the text area, return 2
12263 (try_cursor_movement): Check for the need to scroll more
12264 accurately, and prefer exact match for point under bidi.
12265 Don't advance `row' beyond the last row of the window.
12267 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
12268 into disp_prop; all users changed.
12270 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
12271 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
12272 for the text covered by the display property.

12282 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
12283 buffers, return left-to-right.
12284 (set_cursor_from_row): Consider candidate row a win if its glyph
12285 represents a newline and point is on that newline. Fixes cursor
12286 positioning on the newline at EOL of R2L text within L2R
12287 paragraph, and vice versa.
12288 (try_cursor_movement): Check continued rows, in addition to
12289 continuation rows. Fixes unwarranted scroll when point enters a
12290 continued line of R2L text within an L2R paragraph, or vice versa.
12291 (cursor_row_p): Consider the case of point being equal to
12292 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
12293 from the end of a short line to the beginning of a continued line
12294 of R2L text within L2R paragraph.
12295 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
12296 composed characters.

12309 * nsfont.m (ns_otf_to_script): Fix typo.
12311 2011-08-22 Kenichi Handa <handa@m17n.org>
12313 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
12314 extra slot even if the purpose is char-code-property-table.
12316 2011-08-23 Eli Zaretskii <eliz@gnu.org>
12318 * xdisp.c (redisplay_window): When computing centering_position,
12319 account for the height of the header line. (Bug#8874)
12321 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
12322 instead of CHAR_TO_BYTE. Fixes a crash when a completion
12323 candidate is selected by the mouse, and that candidate has a
12324 composed character under the mouse.
12326 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
12327 coordinates reported by pos-visible-in-window-p for a composed
12328 character in column zero.
12330 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
12332 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
12334 2011-08-22 Eli Zaretskii <eliz@gnu.org>
12336 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
12337 consider it a hit if to_charpos is anywhere in the range of the
12338 composed buffer positions.
12340 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
12342 * image.c (gif_load): Don't assume that each subimage has the same
12343 dimensions as the base image. Handle disposal method that is
12344 "undefined" by the gif spec (Bug#9335).
12346 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
12348 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).
12349 (Fcondition_case): Document `debug' symbol in error handler.
12351 2011-08-19 Eli Zaretskii <eliz@gnu.org>
12353 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
12354 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
12355 from an Org mode buffer to a Speedbar frame.
12357 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
12358 a composition, take its buffer position from IT->cmp_it.charpos.
12359 Fixes cursor positioning at the beginning of a line that begins
12360 with a composed character.
12362 2011-08-18 Eli Zaretskii <eliz@gnu.org>
12364 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
12365 character bidirectional type, use STRONG_L instead. Fixes crashes
12366 in a buffer produced by `describe-categories'.
12368 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
12369 members before the level stack, so they would be saved and
12370 restored when copying iterator state. Fixes incorrect reordering
12371 around TABs covered by display properties.
12373 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
12375 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

12379 * eval.c (internal_condition_case, internal_condition_case_1)
12380 (internal_condition_case_2, internal_condition_case_n):
12381 Remove unnecessary aborts (Bug#9081).
12383 2011-08-17 Eli Zaretskii <eliz@gnu.org>
12385 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
12386 has no `load' handler, try opening the file locally. (Bug#9311)
12388 2011-08-16 Ken Brown <kbrown@cornell.edu>
12390 * gmalloc.c: Expand comment.
12392 2011-08-16 Eli Zaretskii <eliz@gnu.org>
12394 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
12395 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.
12397 2011-08-16 Ken Brown <kbrown@cornell.edu>
12399 Fix memory allocation problems in Cygwin build (Bug#9273).
12401 * unexcw.c ( __malloc_initialized): Declare external variable.
12402 (fixup_executable): Force the dumped emacs to reinitialize malloc.
12404 * gmalloc.c [CYGWIN] (bss_sbrk_heapbase, bss_sbrk_heapinfo):
12406 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the

12432 biditype.h and bidimirror.h.
12434 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
12435 coordinates of the iterator when restoring from ppos_it.
12438 2011-08-14 Kenichi Handa <handa@m17n.org>
12440 * process.c (create_process): Call setup_process_coding_systems
12441 after the pid of the process is set to -1 (Bug#8162).
12443 2011-08-14 Eli Zaretskii <eliz@gnu.org>
12445 * xdisp.c (move_it_in_display_line_to): Don't invoke
12446 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
12447 ppos_it. Fixes vertical cursor motion when line beginning is
12448 covered by an image. (Bug#9296)
12450 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
12452 * nsterm.h (ns_run_ascript): Declare.
12453 (NSAPP_DATA2_RUNASSCRIPT): Define.
12455 * nsfns.m (as_script, as_result, as_status): New static variables.
12456 (ns_run_ascript): New function.
12457 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
12458 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
12459 the event loop. Get status from as_status (Bug#7276).
12461 * nsterm.m (sendEvent): If event is NSApplicationDefined and
12462 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
12463 the event loop (Bug#7276).
12465 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
12467 * gnutls.c (QCgnutls_bootprop_priority)

12488 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
12489 (Fnetwork_interface_list): Allocate in increments of bytes instead
12490 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
12491 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
12493 (struct ifflag_def): notrailers is smart on OSX.
12494 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
12495 Get hardware address with getifaddrs if available.
12497 2011-08-12 Eli Zaretskii <eliz@gnu.org>
12499 * xdisp.c (iterate_out_of_display_property): xassert that
12500 IT->position is set to within IT->object's boundaries. Break from
12501 the loop as soon as EOB is reached; avoids infloops in redisplay
12502 when IT->position is set up wrongly due to some bug.
12503 Set IT->current to match the bidi iterator unconditionally.
12504 (push_display_prop): Allow GET_FROM_STRING as IT->method on
12505 entry. Force push_it to save on the stack the current
12506 buffer/string position, to be restored by pop_it. Fix flags in
12507 the iterator structure wrt the object coming from a display
12508 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
12509 properties. (Bug#9284)
12511 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
12513 * fontset.c (fontset_get_font_group): Add proper type checks.

12519 and LC_VERSION_MIN_MACOSX.
12520 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
12521 (dump_it) [LC_FUNCTION_STARTS]: Use it.
12523 2011-08-08 Eli Zaretskii <eliz@gnu.org>
12525 * xdisp.c (forward_to_next_line_start): Allow to use the
12526 no-display-properties-and-no-overlays under bidi display.
12527 Set disp_pos in the bidi iterator to avoid searches for display
12528 properties and overlays.
12530 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
12532 * editfns.c (Fset_time_zone_rule): Document relationship with the
12535 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
12536 the font entity extracted from the cache (Bug#8109).
12538 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
12540 * composite.c (autocmp_chars): Don't reset point. That is done by
12541 restore_point_unwind (Bug#5984).
12543 2011-08-07 Juri Linkov <juri@jurta.org>
12545 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
12546 to show the arg `TIME' instead of `TIMEVAL'.
12548 2011-08-06 Eli Zaretskii <eliz@gnu.org>
12550 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
12551 display property strides EOL and includes a newline, as in
12552 longlines-mode. (Bug#9254)
12553 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
12554 word-wrap under bidirectional display. (Bug#9224)
12556 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
12557 is non-zero, even if the data buffer is NULL. Fixes a crash in
12558 vertical-motion with longlines-mode. (Bug#9254)
12560 2011-08-05 Eli Zaretskii <eliz@gnu.org>
12562 * bidi.c <bidi_cache_total_alloc>: Now static.
12563 (bidi_initialize): Initialize bidi_cache_total_alloc.
12565 * xdisp.c (display_line): Release buffer allocated for shelved bidi
12568 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
12569 amount allocated this far in `bidi_cache_total_alloc'.
12570 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
12571 non-zero, only free the data buffer without restoring the cache
12572 contents. All callers changed.
12574 * dispextern.h (bidi_unshelve_cache): Update prototype.
12576 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
12577 (move_it_in_display_line, move_it_to)
12578 (move_it_vertically_backward, move_it_by_lines): Replace the call
12579 to xfree to an equivalent call to bidi_unshelve_cache.
12580 (move_it_in_display_line_to): Fix logic of returning
12581 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
12583 2011-08-05 Eli Zaretskii <eliz@gnu.org>
12585 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
12586 came from a string character with a `cursor' property. (Bug#9229)
12588 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
12590 * Makefile.in (LIB_PTHREAD): New variable.
12591 (LIBES): Add LIB_PTHREAD (Bug#9216).
12593 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
12594 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
12596 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
12598 * regex.c (re_iswctype): Remove some redundant boolean conversions.
12600 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
12602 * xterm.c (x_find_topmost_parent): New function.
12603 (x_set_frame_alpha): Find topmost parent window with
12604 x_find_topmost_parent and set the property there also (bug#9181).
12605 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
12607 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
12609 * callproc.c (Fcall_process): Avoid vfork clobbering
12610 the local vars buffer, coding_systems, current_dir.
12612 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
12614 * keymap.c (Fmake_composed_keymap): Move to subr.el.
12616 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
12618 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
12619 so that it is not optimized away.
12621 * xdisp.c (compute_display_string_pos): Remove unused local.
12623 2011-08-02 Eli Zaretskii <eliz@gnu.org>
12625 Fix slow cursor motion and scrolling in large buffers with
12626 selective display, like Org Mode buffers. (Bug#9218)
12628 * dispextern.h (struct bidi_it): New member disp_prop_p.
12630 * xdisp.c: Remove one-slot cache of display string positions.
12631 (compute_display_string_pos): Accept an additional argument
12632 DISP_PROP_P; callers changed. Scan at most 5K characters forward
12633 for a display string or property. If found, set DISP_PROP_P
12636 * bidi.c (bidi_fetch_char): Accept an additional argument
12637 DISP_PROP_P, and pass it to compute_display_string_pos.
12638 Only handle text covered by a display string if DISP_PROP_P is returned
12639 non-zero. All callers of bidi_fetch_char changed.
12641 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
12643 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
12645 2010-12-03 Don March <don@ohspite.net>
12647 * keymap.c (Fdefine_key): Fix non-prefix key error message when
12648 last character M-[char] is translated to ESC [char] (bug#7541).
12650 2011-08-02 Kenichi Handa <handa@m17n.org>
12652 * lisp.h (uniprop_table): Extern it.
12654 * chartab.c (uniprop_table): Make it non-static.
12656 2011-08-01 Eli Zaretskii <eliz@gnu.org>
12658 * xdisp.c (forward_to_next_line_start): Accept additional argument
12659 BIDI_IT_PREV, and store into it the state of the bidi iterator had
12661 (reseat_at_next_visible_line_start): Use the bidi iterator state
12662 returned by forward_to_next_line_start to restore the state of
12663 it->bidi_it after backing up to previous newline. (Bug#9212)
12665 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
12667 * regex.c (re_comp): Protoize.
12668 (re_exec): Fix return type.
12669 (regexec): Fix type of `ret'. (Bug#9203)
12671 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
12673 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
12674 This is needed if max-image-size is a floating-point number.
12676 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
12678 * print.c (print_object): Print empty symbol as ##.
12680 * lread.c (read1): Read ## as empty symbol.
12682 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
12684 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
12685 setting frame foreground color (Bug#9175).
12686 (x_set_background_color): Likewise.
12688 * nsmenu.m (-setText): Size tooltip dimensions precisely to
12689 contents (Bug#9176).
12690 (EmacsTooltip -init): Remove bezels and add shadows to
12693 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
12694 or scroll bar (Bug#8470).
12696 * nsfont.m (nsfont_open): Remove assignment to voffset and
12697 unnecessary vars hshink, expand, hd, full_height, min_height.
12698 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
12700 * nsterm.h (nsfont_info): Remove voffset field.
12702 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
12704 Implement strike-through and overline on NextStep (Bug#8863).
12706 * nsfont.m (nsfont_open): Use underline position provided by font,
12707 instead of hard-coded value of 2.
12708 (nsfont_draw): Call ns_draw_text_decoration instead.
12710 * nsterm.h: Add declaration for ns_draw_text_decoration.
12712 * nsterm.m (ns_draw_text_decoration): New function for drawing
12713 underline, overline, and strike-through.
12714 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
12715 ns_draw_text_decoration. Change treatment of cursor drawing to
12716 accommodate underlining, etc.
12718 2011-07-28 Eli Zaretskii <eliz@gnu.org>
12720 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
12723 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
12725 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
12726 Without this fix, if a signal arrives just after memory fills up,
12727 'malloc' might be invoked reentrantly.
12729 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
12730 In other words, assume that every image size is allowed, on non-X
12731 hosts. This assumption is probably wrong, but it lets Emacs compile.
12733 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
12735 * regex.c (re_iswctype): Convert return values to boolean.
12737 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
12739 * xdisp.c (compute_display_string_pos): Don't use cached display
12740 string position if the buffer had its restriction changed.
12743 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
12745 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
12747 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
12749 Integer signedness and overflow and related fixes. (Bug#9079)
12751 * bidi.c: Integer size and overflow fixes.
12752 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
12753 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
12754 (bidi_cache_find_level_change, bidi_cache_ensure_space)
12755 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
12756 (bidi_find_other_level_edge):
12757 Use ptrdiff_t instead of EMACS_INT where either will do.
12758 This works better on 32-bit hosts configured --with-wide-int.
12759 (bidi_cache_ensure_space): Check for size-calculation overflow.
12760 Use % rather than repeated addition, for better worst-case speed.
12761 Don't set bidi_cache_size until after xrealloc returns, because it
12763 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
12764 (bidi_cache_ensure_space): Also check that the bidi cache size
12765 does not exceed that of the largest Lisp string or buffer. See Eli
12766 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
12768 * alloc.c (__malloc_size_t): Remove.
12769 All uses replaced by size_t. See Andreas Schwab's note
12770 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
12772 * image.c: Improve checking for integer overflow.
12773 (check_image_size): Assume that f is nonnull, since
12774 it is always nonnull in practice. This is one less thing to
12775 worry about when checking for integer overflow later.
12776 (x_check_image_size): New function, which checks for integer
12777 overflow issues inside X.
12778 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
12779 This removes the need for a memory_full check.
12780 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
12781 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
12782 (xbm_read_bitmap_data): Change locals back to 'int', since
12783 their values must fit in 'int'.
12784 (xpm_load_image, png_load, tiff_load):
12785 Invoke x_create_x_image_and_pixmap earlier,
12786 to avoid much needless work if the image is too large.
12787 (tiff_load): Treat overly large images as if
12788 x_create_x_image_and_pixmap failed, not as malloc failures.
12789 (gs_load): Use x_check_image_size.
12791 * gtkutil.c: Omit integer casts.
12792 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
12793 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
12795 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
12797 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
12798 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
12799 would wrongly return t on a 64-bit host.
12801 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
12802 The plain *_OVERFLOW macros run afoul of GCC bug 49705
12803 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
12804 and therefore cause GCC to emit a bogus diagnostic in some cases.
12806 * image.c: Integer signedness and overflow and related fixes.
12807 This is not an exhaustive set of fixes, but it's time to
12808 record what I've got.
12809 (lookup_pixel_color, check_image_size): Remove redundant decls.
12810 (check_image_size): Don't assume that arbitrary EMACS_INT values
12811 fit in 'int', or that arbitrary 'double' values fit in 'int'.
12812 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
12813 (tiff_load, imagemagick_load_image):
12814 Check for overflow in size calculations.
12815 (x_create_x_image_and_pixmap): Remove unnecessary test for
12816 xmalloc returning NULL; that can't happen.
12817 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
12818 (xpm_color_bucket): Use better integer hashing function.
12819 (xpm_cache_color): Don't possibly over-allocate memory.
12820 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
12821 (gif_memory_source):
12822 Use ptrdiff_t, not int or size_t, to record sizes.
12823 (png_load): Don't assume values greater than 2**31 fit in 'int'.
12824 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
12825 either works, as we prefer signed integers.
12826 (tiff_read_from_memory, tiff_write_from_memory):
12827 Return tsize_t, not size_t, since that's what the TIFF API wants.
12828 (tiff_read_from_memory): Don't fail simply because the read would
12829 go past EOF; instead, return a short read.
12830 (tiff_load): Omit no-longer-needed casts.
12831 (Fimagemagick_types): Don't assume size fits into 'int'.
12833 Improve hashing quality when configured --with-wide-int.
12834 * fns.c (hash_string): New function, taken from sxhash_string.
12835 Do not discard information about ASCII character case; this
12836 discarding is no longer needed.
12837 (sxhash-string): Use it. Change sig to match it. Caller changed.
12838 * lisp.h: Declare it.
12839 * lread.c (hash_string): Remove, since we now use fns.c's version.
12840 The fns.c version returns a wider integer if --with-wide-int is
12841 specified, so this should help the quality of the hashing a bit.
12843 * emacs.c: Integer overflow minor fix.
12844 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
12845 Define only if GNU_LINUX.
12846 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
12848 * dispnew.c: Integer signedness and overflow fixes.
12849 Remove unnecessary forward decls, that were a maintenance hassle.
12850 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
12852 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
12853 (scrolling_window): Use ptrdiff_t, not int, for byte count.
12854 (prepare_desired_row, line_draw_cost):
12855 Use int, not unsigned, where either works.
12856 (save_current_matrix, restore_current_matrix):
12857 Use ptrdiff_t, not size_t, where either works.
12858 (init_display): Check for overflow more accurately, and without
12859 relying on undefined behavior.
12861 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
12862 Remove, replacing with the new symbols in lisp.h. All uses changed.
12863 * fileio.c (make_temp_name):
12864 * filelock.c (lock_file_1, lock_file):
12865 * xdisp.c (message_dolog):
12866 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
12867 Use pMd etc. instead.
12868 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
12869 replacing the pWIDE etc. symbols removed from editfns.c.
12871 * keyboard.h (num_input_events): Now uintmax_t.
12872 This is (very slightly) less likely to mess up due to wraparound.
12875 * buffer.c: Integer signedness fixes.
12876 (alloc_buffer_text, enlarge_buffer_text):
12877 Use ptrdiff_t rather than size_t when either will do, as we prefer
12880 * alloc.c: Integer signedness and overflow fixes.
12881 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
12882 (__malloc_size_t): Default to size_t, not to int.
12883 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
12884 (Fgarbage_collect, mark_object_loop_halt, mark_object):
12885 Prefer ptrdiff_t to size_t when either would do, as we prefer
12887 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
12888 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
12889 Now const. Initialize with values that are in range even if char
12891 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
12892 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
12893 These functions do the right thing with sizes > 2**32.
12894 (check_depth): Now ptrdiff_t, not int.
12895 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
12896 Adjust to new way of storing sizes. Check for size overflow bugs
12898 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
12899 slightly wrong anyway, as it missed one instance of
12900 XMALLOC_OVERRUN_CHECK_OVERHEAD.
12901 (refill_memory_reserve): Omit needless cast to size_t.
12902 (mark_object_loop_halt): Mark as externally visible.
12904 * xselect.c: Integer signedness and overflow fixes.
12905 (Fx_register_dnd_atom, x_handle_dnd_message):
12906 Use ptrdiff_t, not size_t, since we prefer signed.
12907 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
12908 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
12909 x_dnd_atoms_size and x_dnd_atoms_length.
12911 * doprnt.c: Prefer signed to unsigned when either works.
12913 * doprnt.c (doprnt):
12915 * xdisp.c (vmessage):
12916 Use ptrdiff_t, not size_t, when using or implementing doprnt,
12917 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
12918 prefer signed arithmetic to avoid comparison confusion.
12919 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
12920 but is a bit tricky.
12922 Assume freestanding C89 headers, string.h, stdlib.h.
12923 * data.c, doprnt.c, floatfns.c, print.c:
12924 Include float.h unconditionally.
12925 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
12926 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
12927 * regex.c: Likewise for stddef.h, string.h.
12928 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
12929 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
12930 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
12931 (STDC_HEADERS): Remove obsolete defines.
12932 * sysdep.c: Include limits.h unconditionally.
12934 Assume support for memcmp, memcpy, memmove, memset.
12935 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
12936 * regex.c (memcmp, memcpy):
12937 Remove; we assume C89 now.
12939 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
12940 (__malloc_safe_bcopy): Remove; no longer needed.
12942 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
12943 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
12944 well either way, and we prefer signed to unsigned.
12946 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
12948 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
12949 closes the connection while we're reading (bug#9182).
12951 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
12953 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
12954 are specified (Bug#9168).
12956 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
12958 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
12959 Found by GCC static checking and --with-wide-int on a 32-bit host.
12961 2011-07-25 Eli Zaretskii <eliz@gnu.org>
12963 * xdisp.c (compute_display_string_pos): Fix logic of caching
12964 previous display string position. Initialize cached_prev_pos to
12965 -1. Fixes slow-down at the beginning of a buffer.
12967 2011-07-24 Eli Zaretskii <eliz@gnu.org>
12969 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
12970 for attrs[LFACE_FONTSET_INDEX].
12972 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
12974 * xml.c (parse_region): Remove unused local
12975 that was recently introduced.
12977 2011-07-23 Eli Zaretskii <eliz@gnu.org>
12979 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
12980 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
12982 * xdisp.c (move_it_in_display_line_to): Record the best matching
12983 position for TO_CHARPOS while scanning the line, and restore it on
12984 exit if none of the characters scanned was an exact match.
12985 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
12986 when exact match is impossible due to invisible text, and the
12987 lines are truncated.
12989 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
12991 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
12994 2011-07-22 Eli Zaretskii <eliz@gnu.org>
12996 Fix a significant slow-down of cursor motion with C-n, C-p,
12997 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
12998 auto-repeat under bidi redisplay in fontified buffers.
12999 * xdisp.c (compute_stop_pos_backwards): New function.
13000 (next_element_from_buffer): Call compute_stop_pos_backwards to
13001 find a suitable prev_stop when we find ourselves before
13003 (reseat): Don't look for prev_stop, as that could mean a very long
13005 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
13006 <cached_disp_overlay_modiff>: Cache for last found display string
13008 (compute_display_string_pos): Return the cached position if asked
13009 about the same buffer in the same area of character positions, and
13010 the buffer wasn't changed since the time the display string
13011 position was cached.
13013 2011-07-22 Eli Zaretskii <eliz@gnu.org>
13015 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
13016 is an integer, which is important for empty lines. (Bug#9149)
13018 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
13020 * frame.c (Fmodify_frame_parameters): In tty case, update the
13021 default face if necessary (Bug#4238).
13023 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
13025 * editfns.c (Fstring_to_char): No need to explain what a character
13026 is in the docstring (Bug#6576).
13028 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
13030 * xml.c (parse_region): Make sure we always return a tree.
13032 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
13034 * xml.c (parse_region): If a document contains only comments,
13037 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
13039 * xml.c (make_dom): Return comments, too.
13041 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
13044 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
13045 and the surrounding thread.
13046 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
13047 rather than fgets, and retry after EINTR. Otherwise, 'emacs
13048 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
13050 * s/openbsd.h (BROKEN_SIGIO): Define.
13051 * unexelf.c (unexec) [__OpenBSD__]:
13052 Don't update the .mdebug section of the Alpha COFF symbol table.
13054 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
13056 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
13059 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
13061 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
13062 This fixes some race conditions on the permissions of any newly
13065 * alloc.c (valid_pointer_p): Use pipe, not open.
13066 This fixes some permissions issues when debugging.
13068 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
13069 If fchown fails to set both uid and gid, try to set just gid,
13070 as that is sometimes allowed. Adjust the file's mode to eliminate
13071 setuid or setgid bits that are inappropriate if fchown fails.
13073 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
13075 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ

13081 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
13083 * lread.c (read_integer): Unread even EOF character.
13084 (read1): Likewise. Properly record start position of symbol.

13087 symbol character follows.
13089 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
13091 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
13092 This works around a problem with the previous change to Fcopy_file.
13093 Recent glibc declares fchown with __attribute__((warn_unused_result)),
13094 and without this change, GCC might complain about discarding
13095 fchown's return value.
13097 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
13099 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
13101 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
13103 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
13105 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
13107 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
13108 it's used from the C level.
13110 * process.c: Use the same condition for POLL_FOR_INPUT in both
13111 keyboard.c and process.c (bug#1858).
13113 2011-07-09 Lawrence Mitchell <wence@gmx.li>
13115 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
13116 (Fgnutls_boot): Use it.
13118 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
13120 * doc.c (Fsubstitute_command_keys): Revert last change.
13122 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
13124 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
13125 quotes the next character, and doesn't affect other longer
13126 sequences (bug#8935).
13128 * lread.c (syms_of_lread): Clarify that is isn't only
13129 `eval-buffer' and `eval-defun' that's affected by
13130 `lexical-binding' (bug#8460).
13132 2011-07-15 Eli Zaretskii <eliz@gnu.org>
13134 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
13135 bidi redisplay when a line includes both an image and is truncated.
13137 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
13139 Fix minor problems found by static checking.
13140 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
13141 (elsz): Now a signed constant, not a size_t var. We prefer signed
13142 types to unsigned, to avoid integer comparison confusion. Without
13143 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
13144 "cannot optimize loop, the loop counter may overflow", a symptom
13146 * indent.c (Fvertical_motion): Mark locals as initialized.
13147 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
13149 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>

13172 buffer position was specified. Initialize paragraph_embedding to
13174 (reseat_to_string): Initialize the bidi iterator.
13175 (display_string): If we need to ignore text properties of
13176 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
13177 original value of -1 will not work with bidi.)
13178 (compute_display_string_pos): First arg is now struct
13179 `text_pos *'; all callers changed. Support display properties on
13181 (compute_display_string_end): Support display properties on Lisp
13183 (init_iterator, reseat_1, reseat_to_string): Initialize the
13184 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
13185 when iterating on a string not from display properties).
13186 (compute_display_string_pos, compute_display_string_end):
13187 Fix calculation of the object to scan. Fixes an error when using
13189 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
13190 base_level_stop; instead, set base_level_stop to BEGV.
13191 Fixes crashes in vertical-motion.
13192 (next_element_from_buffer): Improve commentary for when
13193 the iterator is before prev_stop.
13194 (init_iterator): Initialize bidi_p from the default value of
13195 bidi-display-reordering, not from buffer-local value. Use the
13196 buffer-local value only if initializing for buffer iteration.
13197 (handle_invisible_prop): Support invisible properties on strings
13198 that are being bidi-reordered.

13206 (init_iterator): Don't initialize it->bidi_p for strings
13208 (reseat_to_string): Initialize it->bidi_p for strings here.

13217 parts of next_element_from_buffer, next_element_from_string, and
13218 next_element_from_c_string.
13219 (tool_bar_lines_needed, redisplay_tool_bar)
13220 (display_menu_bar): Force left-to-right direction. Add a FIXME
13221 comment for making that be controlled by a user option.

13230 (get_overlay_strings_1, push_display_prop): Set up the bidi
13231 iterator for displaying display or overlay strings.
13232 (forward_to_next_line_start): Don't use the shortcut if
13234 (back_to_previous_visible_line_start): If handle_display_prop
13235 pushed the iterator stack, restore the internal state of the bidi
13236 iterator by calling bidi_pop_it same number of times.
13237 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
13238 and we are bidi-iterating, don't decrement the iterator position;
13239 instead, set the first_elt flag in the bidi iterator, to produce
13241 (reseat_1): Remove redundant setting of string_from_display_prop_p.
13242 (push_display_prop): xassert that we are iterating a buffer.
13243 (push_it, pop_it): Save and restore paragraph_embedding member.
13244 (handle_single_display_spec, next_overlay_string)
13245 (get_overlay_strings_1, reseat_1, reseat_to_string)
13246 (push_display_prop): Set up the `unibyte' member of bidi_it.string
13247 correctly. Don't assume unibyte strings are not bidi-reordered.
13248 (compute_display_string_pos)
13249 (compute_display_string_end): Fix handling the case of C string.

13255 popping after iteration over a string that came from a display
13256 property. Fix a typo in popping stretch info. Add an assertion
13257 for verifying that the iterator position is in sync with the bidi
13259 (handle_single_display_spec, get_overlay_strings_1)

13273 (try_scrolling, redisplay_window, display_line): Use them when
13274 saving a temporary copy of the iterator and restoring it back.
13275 (back_to_previous_visible_line_start, reseat_1)
13276 (init_iterator): Empty the bidi cache "stack".
13277 (move_it_in_display_line_to): If iterator ended up at

13284 displayed in margins. (Bug#8133) (Bug#8867)
13285 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past

13313 changed to -1 and -2, respectively.
13314 (bidi_char_at_pos): New function.
13315 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak):

13348 (bidi_push_it, bidi_pop_it): Add prototypes.
13349 (struct iterator_stack_entry): New members bidi_p,
13350 paragraph_embedding, and from_disp_prop_p.

13398 Pass Qx_lost_selection_functions rather than
13399 Vx_lost_selection_functions to Frun_hook_with_args.
13401 2011-07-13 Paul Eggert <eggert@cs.ucla.edu>
13403 * buffer.c (Fget_buffer_create): Initialize inhibit_shrinking.
13404 The old code sometimes used this field without initializing it.
13406 * alloc.c (gc_sweep): Don't read past end of array.
13407 In theory, the old code could also have corrupted Emacs internals,
13408 though it'd be very unlikely.
13410 2011-07-12 Andreas Schwab <schwab@linux-m68k.org>
13412 * character.c (Fcharacterp): Don't advertise optional ignored
13413 argument. (Bug#4026)

13671 (clone_per_buffer_values): Don't assume that

13673 This isn't true in general, and it's particularly not true
13674 if Emacs is configured with --with-wide-int.
13675 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
13676 New macros, used in the buffer.c change.

13712 Random fixes. E.g., (random) never returned negative values.
13713 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
13714 subseconds part to the entropy, as that's a bit more random.
13715 Prefer signed to unsigned, since the signedness doesn't matter and
13716 in general we prefer signed. When given a limit, use a
13717 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
13718 latter isn't right if USE_2_TAGS_FOR_INTS.
13719 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
13720 not 0..VALMASK. Don't discard "excess" bits that random () returns.

13732 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
13733 This is more efficient than Ffile_directory_p and avoids a minor race.
13735 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
13737 * buffer.c (Foverlay_put): Say what the return value is
13740 * fileio.c (barf_or_query_if_file_exists): Check first if the file
13741 is a directory before asking whether to use the file name
13743 (barf_or_query_if_file_exists): Make the "File is a directory"
13744 error be more correct.
13746 * fns.c (Frequire): Remove the mention of the .gz files, since
13747 that's installation-specific, but keep the mention of
13748 `get-load-suffixes'.

13752 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

13763 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
13764 Also (re)move comments that are misplaced or no longer relevant.

13791 2011-07-02 Lars Magne Ingebrigtsen <larsi@gnus.org>
13793 * lread.c (syms_of_lread): Mention single symbols defined by
13794 `defvar' or `defconst' (bug#7154).
13796 * fns.c (Frequire): Mention .el.gz files (bug#7314).
13797 (Frequire): Mention get-load-suffixes.

13825 minibuffer-local-must-match-map, and
13826 minibuffer-local-filename-must-match-map to Elisp.
13827 (syms_of_keymap): Defsubr make-composed-keymap.
13828 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

13865 * eval.c (struct backtrace): Simplify and port the data structure.
13866 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
13867 signed bit field, as this assumption is not portable and it makes
13868 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
13869 "char debug_on_exit : 1" as this is not portable either; instead,
13870 use the portable "unsigned int debug_on_exit : 1". Remove unused
13871 member evalargs. Remove obsolete comments about cc bombing out.

14037 Integer and buffer overflow fixes (Bug#8873).
14039 * print.c (printchar, strout): Check for string overflow.
14040 (PRINTPREPARE, printchar, strout):
14041 Don't set size unless allocation succeeds.
14043 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
14044 for sizes. Check for string overflow more accurately.
14045 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
14047 * macros.c: Integer and buffer overflow fixes.
14048 * keyboard.h (struct keyboard.kbd_macro_bufsize):
14049 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

14053 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
14055 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
14057 * lread.c: Integer overflow fixes.
14058 (read_integer): Radix is now EMACS_INT, not int,
14059 to improve quality of diagnostics for out-of-range radices.
14060 Calculate buffer size correctly for out-of-range radices.
14061 (read1): Check for integer overflow in radices, and in
14062 read-circle numbers.
14063 (read_escape): Avoid int overflow.
14064 (Fload, openp, read_buffer_size, read1)
14065 (substitute_object_recurse, read_vector, read_list, map_obarray):
14066 Use ptrdiff_t, not int, for sizes.

14081 2011-06-22 Leo Liu <sdl.web@gmail.com>
14083 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
14084 Move to minibuffer.el.
14086 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
14088 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
14089 The following patches are for when GLYPH_DEBUG && !XASSERT.
14090 * dispextern.h (trace_redisplay_p, dump_glyph_string):
14091 * dispnew.c (flush_stdout):
14092 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
14093 Mark as externally visible.
14094 * dispnew.c (check_window_matrix_pointers): Now static.
14095 * dispnew.c (window_to_frame_vpos):
14096 * xfns.c (unwind_create_frame):
14097 * xterm.c (x_check_font): Remove unused local.
14098 * scroll.c (CHECK_BOUNDS):
14099 * xfaces.c (cache_fache): Rename local to avoid shadowing.
14100 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
14101 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
14102 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
14103 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
14105 (debug_method_add): Use va_list and vsprintf rather than relying
14106 on undefined behavior with wrong number of arguments.
14107 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
14108 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
14109 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
14110 since we're not interested in debugging glyphs with old libraries.
14111 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
14112 GCC 4.6.0's static checking.
14114 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
14116 Integer overflow and signedness fixes (Bug#8873).

14127 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
14128 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
14130 * xfaces.c (load_pixmap):

14132 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
14133 (.bitmaps_last, struct x_output.icon_bitmap):
14134 Use ptrdiff_t, not int, for bitmap indexes.
14135 (x_allocate_bitmap_record): Check for size overflow.
14136 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
14138 Use ptrdiff_t, not int, for overlay counts.
14139 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
14140 * editfns.c (overlays_around, get_pos_property):
14141 * textprop.c (get_char_property_and_overlay):
14142 * xdisp.c (next_overlay_change, note_mouse_highlight):
14143 * xfaces.c (face_at_buffer_position):
14144 * buffer.c (OVERLAY_COUNT_MAX): New macro.
14145 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
14146 (Fnext_overlay_change, Fprevious_overlay_change)
14147 (mouse_face_overlay_overlaps, Foverlays_in):
14148 Use ptrdiff_t, not int, for sizes.
14149 (overlays_at, overlays_in): Check for size-calculation overflow.
14151 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
14153 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
14154 (x_session_initialize): Do not assume string length fits in int.
14156 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
14157 This is unlikely, but can occur if DPI is outlandish.
14159 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
14160 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
14162 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
14163 * xrdb.c (magic_file_p, search_magic_path):
14164 Omit last arg SUFFIX; it was always 0. All callers changed.
14165 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
14167 * xfont.c (xfont_match): Avoid need for strlen.
14169 * xfns.c: Don't assume strlen fits in int.

14172 * xdisp.c (message_log_check_duplicate): Return intmax_t,
14173 not unsigned long, as we prefer signed integers. All callers changed.
14174 Detect integer overflow in repeat count.
14175 (message_dolog): Don't assume print length fits in 39 bytes.
14176 (display_mode_element): Don't assume strlen fits in int.
14178 * termcap.c: Don't assume sizes fit in int and never overflow.
14179 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
14180 (gobble_line): Check for size-calculation overflow.
14182 * minibuf.c (Fread_buffer):
14183 * lread.c (intern, intern_c_string):
14184 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:

14194 Don't assume integer property fits in fixnum.
14195 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
14197 * filelock.c: Fix some buffer overrun and integer overflow issues.
14198 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
14199 Reformulate so as not to need the command string.
14200 Invoke gzip -cd rather than gunzip, as it's more portable.
14201 (lock_info_type, lock_file_1, lock_file):
14202 Don't assume pid_t and time_t fit in unsigned long.
14203 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
14204 (current_lock_owner): Prefer signed type for sizes.
14205 Use memcpy, not strncpy, where memcpy is what is really wanted.
14206 Don't assume (via atoi) that time_t and pid_t fit in int.
14207 Check for time_t and/or pid_t out of range, e.g., via a network share.
14208 Don't alloca where an auto var works fine.
14210 * fileio.c: Fix some integer overflow issues.
14211 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
14212 Don't assume string length fits in int.
14213 (directory_file_name): Don't assume string length fits in long.
14214 (make_temp_name): Don't assume pid fits in int, or that its print
14215 length is less than 20.
14217 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
14219 * coding.c (make_subsidiaries): Don't assume string length fits in int.
14221 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
14223 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.

14226 * emacs.c: Don't assume string length fits in 'int'.
14227 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
14228 (main): Don't invoke strlen when not needed.

14233 * callproc.c (getenv_internal_1, getenv_internal)
14234 (Fgetenv_internal):
14235 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
14237 * lread.c (invalid_syntax): Omit length argument.
14238 All uses changed. This doesn't fix a bug, but it simplifies the
14239 code away from its former Hollerith-constant appearance, and it's
14240 one less 'int' to worry about when looking at integer-overflow issues.
14241 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
14243 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
14244 This didn't break anything, but it didn't help either.
14245 It's confusing to put a bogus integer in a place where the actual
14246 value does not matter.
14247 (LIST_END_P): Remove unused macro and its bogus comment.
14248 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
14250 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
14251 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
14253 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
14254 We prefer signed types, and the value cannot exceed the EMACS_INT
14255 range anyway (because otherwise the length would not be representable).
14256 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
14257 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
14258 This avoids a GCC warning when WIDE_EMACS_INT.
14260 * indent.c (sane_tab_width): New function.
14261 (current_column, scan_for_column, Findent_to, position_indentation)
14262 (compute_motion): Use it. This is just for clarity.
14263 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
14265 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
14267 * lisp.h (lint_assume): New macro.
14268 * composite.c (composition_gstring_put_cache):
14269 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
14271 * editfns.c, insdel.c:
14272 Omit unnecessary forward decls, to simplify future changes.
14274 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
14276 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
14278 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
14279 Use much-faster test for byte-length change.
14280 Don't assume string byte-length fits in 'int'.
14281 Check that character arg fits in 'int'.
14282 (mapcar1): Declare byte as byte, for clarity.
14284 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
14286 * fns.c (concat): Catch string overflow earlier.
14287 Do not rely on integer wraparound.
14289 * dispextern.h (struct it.overlay_strings_charpos)
14290 (struct it.selective): Now EMACS_INT, not int.
14291 * xdisp.c (forward_to_next_line_start)
14292 (back_to_previous_visible_line_start)
14293 (reseat_at_next_visible_line_start, next_element_from_buffer):
14294 Don't arbitrarily truncate the value of 'selective' to int.
14296 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
14298 * composite.c: Don't truncate sizes to 'int'.
14299 (composition_gstring_p, composition_reseat_it)
14300 (composition_adjust_point): Use EMACS_INT, not int.
14301 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
14302 not EMACS_UINT, for indexes.
14304 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
14306 * buffer.c: Include <verify.h>.
14307 (struct sortvec.priority, struct sortstr.priority):
14308 Now EMACS_INT, not int.
14309 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
14310 (struct sortstr.size, record_overlay_string)
14311 (struct sortstrlist.size, struct sortlist.used):
14312 Don't truncate size to int.
14313 (record_overlay_string): Check for size-calculation overflow.
14314 (init_buffer_once): Check at compile-time, not run-time.
14316 2011-06-22 Jim Meyering <meyering@redhat.com>
14318 Don't leak an XBM-image-sized buffer
14319 * image.c (xbm_load): Free the image buffer after using it.
14321 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
14324 * composite.c (find_automatic_composition): Omit needless 'return 0;'
14325 that Sun C diagnosed.
14326 * fns.c (secure_hash): Fix pointer signedness issue.
14327 * intervals.c (static_offset_intervals): New function.
14328 (offset_intervals): Use it.
14330 2011-06-21 Leo Liu <sdl.web@gmail.com>
14333 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
14336 * fns.c (secure_hash): Rename from crypto_hash_function and change
14337 the first arg to accept symbols.
14338 (Fsecure_hash): New primitive.
14339 (syms_of_fns): New symbols.
14341 2011-06-20 Deniz Dogan <deniz@dogan.se>
14343 * process.c (Fset_process_buffer): Clarify return value in
14346 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
14348 * dispnew.c (add_window_display_history): Use BVAR.
14350 * xdisp.c (debug_method_add): Use BVAR.
14351 (check_window_end, dump_glyph_matrix, dump_glyph)
14352 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
14354 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
14357 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
14358 check till after the cache is created in init_frame_faces.
14360 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
14362 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
14364 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
14366 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
14367 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
14368 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
14370 Improve buffer-overflow checking (Bug#8873).
14371 * fileio.c (Finsert_file_contents):
14372 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
14373 Remove the old (too-loose) buffer overflow checks.
14374 They weren't needed, since make_gap checks for buffer overflow.
14375 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
14376 The old code merely checked for Emacs fixnum overflow, and relied
14377 on undefined (wraparound) behavior. The new code avoids undefined
14378 behavior, and also checks for ptrdiff_t and/or size_t overflow.
14380 * editfns.c (Finsert_char): Don't dump core with very negative counts.
14381 Tune. Don't use wider integers than needed. Don't use alloca.
14382 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
14384 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
14386 * insdel.c, lisp.h (buffer_overflow): New function.
14387 (insert_from_buffer_1, replace_range, replace_range_2):
14388 * insdel.c (make_gap_larger):
14389 * editfns.c (Finsert_char):
14390 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
14392 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
14394 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
14396 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
14398 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
14399 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
14401 * fileio.c: Don't assume EMACS_INT fits in off_t.
14402 (emacs_lseek): New static function.
14403 (Finsert_file_contents, Fwrite_region): Use it.
14404 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
14406 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
14408 * fns.c: Don't overflow int when computing a list length.
14409 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
14410 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
14411 truncation on 64-bit hosts. Check for QUIT every
14412 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
14413 faster and is responsive enough.
14414 (Flength): Report an error instead of overflowing an integer.
14415 (Fsafe_length): Return a float if the value is not representable
14416 as a fixnum. This shouldn't happen except in contrived situations.
14417 (Fnthcdr, Fsort): Don't assume list length fits in int.
14418 (Fcopy_sequence): Don't assume vector length fits in int.
14420 * alloc.c: Check that resized vectors' lengths fit in fixnums.
14421 (header_size, word_size): New constants.
14422 (allocate_vectorlike): Don't check size overflow here.
14423 (allocate_vector): Check it here instead, since this is the only
14424 caller of allocate_vectorlike that could cause overflow.
14425 Check that the new vector's length is representable as a fixnum.
14427 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
14428 The previous code was bogus. For example, next_almost_prime (32)
14429 returned 39, which is undesirable as it is a multiple of 3; and
14430 next_almost_prime (24) returned 25, which is a multiple of 5 so
14431 why was the code bothering to check for multiples of 7?
14433 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
14435 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
14437 Variadic C functions now count arguments with ptrdiff_t.
14438 This partly undoes my 2011-03-30 change, which replaced int with size_t.
14439 Back then I didn't know that the Emacs coding style prefers signed int.
14440 Also, in the meantime I found a few more instances where arguments
14441 were being counted with int, which may truncate counts on 64-bit
14442 machines, or EMACS_INT, which may be unnecessarily wide.
14443 * lisp.h (struct Lisp_Subr.function.aMANY)
14444 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
14445 Arg counts are now ptrdiff_t, not size_t.
14446 All variadic functions and their callers changed accordingly.
14447 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
14448 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
14449 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
14450 * callint.c (Fcall_interactively): Check arg count for overflow,
14451 to avoid potential buffer overrun. Use signed char, not 'int',
14452 for 'varies' array, so that we needn't bother to check its size
14453 calculation for overflow.
14454 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
14455 * eval.c (apply_lambda):
14456 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
14457 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
14458 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
14460 * callint.c (Fcall_interactively): Don't use index var as event count.
14462 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
14463 * mem-limits.h (SIZE): Remove; no longer used.
14465 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
14467 Remove unnecessary casts.
14468 * xterm.c (x_term_init):
14469 * xfns.c (x_set_border_pixel):
14470 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
14471 These aren't needed now that we assume ANSI C.
14473 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
14474 It's more likely to cause problems (due to unsigned overflow)
14477 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
14479 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
14481 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
14483 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
14485 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
14487 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
14489 GLYPH_CODE_FACE returns EMACS_INT, not int.
14490 * dispextern.h (merge_faces):
14491 * xfaces.c (merge_faces):
14492 * xdisp.c (get_next_display_element, next_element_from_display_vector):
14493 Don't assume EMACS_INT fits in int.
14495 * character.h (CHAR_VALID_P): Remove unused parameter.
14496 * fontset.c, lisp.h, xdisp.c: All uses changed.
14498 * editfns.c (Ftranslate_region_internal): Omit redundant test.
14500 * fns.c (concat): Minor tuning based on overflow analysis.
14501 This doesn't fix any bugs. Use int to hold character, instead
14502 of constantly refetching from Emacs object. Use XFASTINT, not
14503 XINT, for value known to be a character. Don't bother comparing
14504 a single byte to 0400, as it's always less.
14506 * floatfns.c (Fexpt):
14507 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
14509 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
14512 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
14514 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
14515 Without this fix, on a 64-bit host (aset S 0 4294967386) would
14516 incorrectly succeed when S was a string, because 4294967386 was
14517 truncated before it was used.
14519 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
14520 Otherwise, an out-of-range integer could cause undefined behavior
14523 * composite.c: Use int, not EMACS_INT, for characters.
14524 (fill_gstring_body, composition_compute_stop_pos): Use int, not
14525 EMACS_INT, for values that are known to be in character range.
14526 This doesn't fix any bugs but is the usual style inside Emacs and
14527 may generate better code on 32-bit machines.
14529 Make sure a 64-bit char is never passed to ENCODE_CHAR.
14530 This is for reasons similar to the recent CHAR_STRING fix.
14531 * charset.c (Fencode_char): Check that character arg is actually
14532 a character. Pass an int to ENCODE_CHAR.
14533 * charset.h (ENCODE_CHAR): Verify that the character argument is no
14534 wider than 'int', as a compile-time check to prevent future regressions
14537 * character.c (char_string): Remove unnecessary casts.
14539 Make sure a 64-bit char is never passed to CHAR_STRING.
14540 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
14541 by silently ignoring the top 32 bits, allowing some values
14542 that were far too large to be valid characters.
14543 * character.h: Include <verify.h>.
14544 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
14545 arguments are no wider than unsigned, as a compile-time check
14546 to prevent future regressions in this area.
14548 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
14549 (Fsubst_char_in_region):
14551 * xdisp.c (decode_mode_spec_coding):
14552 Adjust to CHAR_STRING's new requirement.
14553 * editfns.c (Finsert_char, Fsubst_char_in_region):
14554 * fns.c (concat): Check that character args are actually
14555 characters. Without this test, these functions did the wrong
14556 thing with wildly out-of-range values on 64-bit hosts.
14558 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
14559 These casts should not be needed on 32-bit hosts, either.
14560 * keyboard.c (read_char):
14561 * lread.c (Fload): Remove casts to unsigned.
14563 * lisp.h (UNSIGNED_CMP): New macro.
14564 This fixes comparison bugs on 64-bit hosts.
14565 (ASCII_CHAR_P): Use it.
14566 * casefiddle.c (casify_object):
14567 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
14568 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
14569 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
14570 * dispextern.h (FACE_FROM_ID):
14571 * keyboard.c (read_char): Use UNSIGNED_CMP.
14573 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
14574 not to EMACS_INT, to avoid GCC warning.
14576 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
14578 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
14579 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
14580 isn't needed on 32-bit machines.
14582 * buffer.c (Fgenerate_new_buffer_name):
14583 Use EMACS_INT for count, not int.
14584 (advance_to_char_boundary): Return EMACS_INT, not int.
14586 * data.c (Qcompiled_function): Now static.
14588 * window.c (window_body_lines): Now static.
14590 * image.c (gif_load): Rename local to avoid shadowing.
14592 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
14593 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
14594 * alloc.c (make_save_value): Integer argument is now of type
14595 ptrdiff_t, not int.
14596 (mark_object): Use ptrdiff_t, not int.
14597 * lisp.h (pD): New macro.
14598 * print.c (print_object): Use it.
14600 * alloc.c: Use EMACS_INT, not int, to count objects.
14601 (total_conses, total_markers, total_symbols, total_vector_size)
14602 (total_free_conses, total_free_markers, total_free_symbols)
14603 (total_free_floats, total_floats, total_free_intervals)
14604 (total_intervals, total_strings, total_free_strings):
14605 Now EMACS_INT, not int. All uses changed.
14606 (Fgarbage_collect): Compute overall total using a double, so that
14607 integer overflow is less likely to be a problem. Check for overflow
14608 when converting back to an integer.
14609 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
14610 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
14611 These were 'int' variables that could overflow on 64-bit hosts;
14612 they were never used, so remove them instead of repairing them.
14613 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
14614 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
14615 Previously, this ceilinged at INT_MAX, but that doesn't work on
14617 (allocate_pseudovector): Don't use EMACS_INT when int would do.
14619 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
14620 (allocate_vectorlike): Check for ptrdiff_t overflow.
14621 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
14622 when a (possibly-narrower) signed value would do just as well.
14623 We prefer using signed arithmetic, to avoid comparison confusion.
14625 * alloc.c: Catch some string size overflows that we were missing.
14626 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
14627 for convenience in STRING_BYTES_MAX.
14628 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
14629 The definition here is exact; the one in lisp.h was approximate.
14630 (allocate_string_data): Check for string overflow. This catches
14631 some instances we weren't catching before. Also, it catches
14632 size_t overflow on (unusual) hosts where SIZE_MAX <= min
14633 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
14634 and ptrdiff_t and EMACS_INT are both 64 bits.
14636 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
14637 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
14638 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
14640 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
14642 * alloc.c (Fmake_string): Check for out-of-range init.
14644 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
14646 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
14648 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
14650 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
14651 xg_get_default_scrollbar_width.
14653 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
14654 (int_gtk_range_get_value): Move to the scroll bar part of the file.
14655 (style_changed_cb): Call update_theme_scrollbar_width and call
14656 x_set_scroll_bar_default_width and xg_frame_set_char_size for
14657 all frames (Bug#8505).
14658 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
14659 Call gtk_window_set_resizable if HAVE_GTK3.
14660 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
14661 and height if HAVE_GTK3 (Bug#8505).
14662 (scroll_bar_width_for_theme): New variable.
14663 (update_theme_scrollbar_width): New function.
14664 (xg_get_default_scrollbar_width): Move code to
14665 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
14666 (xg_initialize): Call update_theme_scrollbar_width.
14668 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
14670 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
14672 2011-06-12 Martin Rudalics <rudalics@gmx.at>
14674 * frame.c (make_frame): Call other_buffer_safely instead of
14677 * window.c (temp_output_buffer_show): Call display_buffer with
14678 second argument Vtemp_buffer_show_specifiers and reset latter
14679 immediately after the call.
14680 (Vtemp_buffer_show_specifiers): New variable.
14681 (auto_window_vscroll_p, next_screen_context_lines)
14682 (Vscroll_preserve_screen_position): Remove leading asterisks from
14685 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
14687 Fix minor problems found by GCC 4.6.0 static checking.
14688 * buffer.c (Qclone_number): Remove for now, as it's unused.
14689 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
14690 (record_buffer): Remove unused local.
14691 * frame.c (other_visible_frames, frame_buffer_list): Now static.
14692 (set_frame_buffer_list): Remove; unused.
14693 * frame.h (other_visible_frames): Remove decl.
14694 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
14695 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
14696 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
14698 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
14699 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
14700 Define only if HAVE_GPM.
14701 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
14702 (update_hints_inhibit): Remove; never set. All uses removed.
14703 * widgetprv.h (emacsFrameClassRec): Remove decl.
14704 * window.c (delete_deletable_window): Now returns void, since it
14705 wasn't returning anything.
14706 (compare_window_configurations): Remove unused locals.
14707 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
14708 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
14709 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
14710 the same widths as pointers. This follows up on the 2011-05-06 patch.
14711 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
14712 * xterm.h: Likewise.
14713 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.
14715 2011-06-12 Juanma Barranquero <lekktu@gmail.com>
14717 * makefile.w32-in: Update dependencies.
14718 (LISP_H): Add lib/intprops.h.
14720 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
14722 * image.c (gif_load): Add animation frame delay to the metadata.
14723 (syms_of_image): Use DEFSYM. New symbol `delay'.
14725 2011-06-11 Martin Rudalics <rudalics@gmx.at>
14727 * window.c (delete_deletable_window): Re-add.
14728 (Fset_window_configuration): Rewrite to handle dead buffers and
14729 consequently deletable windows.
14730 (window_tree, Fwindow_tree): Remove. Supply functionality in
14732 (compare_window_configurations): Simplify code.
14734 2011-06-11 Andreas Schwab <schwab@linux-m68k.org>
14736 * image.c (imagemagick_load_image): Fix type mismatch.
14737 (Fimagemagick_types): Likewise.

15190 in the current matrix if keep_current_p is non-zero.
15192 2011-06-04 Eli Zaretskii <eliz@gnu.org>
15194 * bidi.c (bidi_level_of_next_char): Fix last change.
15196 2011-06-03 Eli Zaretskii <eliz@gnu.org>
15198 Support bidi reordering of text covered by display properties.
15200 * bidi.c (bidi_copy_it): Use offsetof instead of emulating it.
15201 (bidi_fetch_char, bidi_fetch_char_advance): New functions.
15202 (bidi_cache_search, bidi_cache_iterator_state)
15203 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
15204 (bidi_level_of_next_char, bidi_move_to_visually_next):
15205 Support character positions inside a run of characters covered by a
15207 (bidi_paragraph_init, bidi_resolve_explicit_1)
15208 (bidi_level_of_next_char): Call bidi_fetch_char and
15209 bidi_fetch_char_advance instead of FETCH_CHAR and
15210 FETCH_CHAR_ADVANCE.
15211 (bidi_init_it): Initialize new members.
15212 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
15214 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
15215 instead of using explicit *_CHAR codes.
15216 (bidi_resolve_explicit, bidi_resolve_weak):
15217 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
15218 bidirectional text is supported only in multibyte buffers.
15219 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
15220 it to initialize the frame_window_p member of struct bidi_it.
15221 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
15222 (bidi_resolve_explicit, bidi_resolve_weak)
15223 (bidi_level_of_next_char, bidi_move_to_visually_next): Abort if
15224 bidi_it->nchars is non-positive.
15225 (bidi_level_of_next_char): Don't try to lookup the cache for the
15226 next/previous character if nothing is cached there yet, or if we
15227 were just reseat()'ed to a new position.
15229 * xdisp.c (set_cursor_from_row): Set start and stop points
15230 according to the row's direction when priming the loop that looks
15231 for the glyph on which to display cursor.
15232 (single_display_spec_intangible_p): Function deleted.
15233 (display_prop_intangible_p): Reimplement to call
15234 handle_display_spec instead of single_display_spec_intangible_p.
15235 Accept 3 additional arguments needed by handle_display_spec.
15236 This fixes incorrect cursor motion across display property with complex
15237 values: lists, `(when COND...)' forms, etc.
15238 (single_display_spec_string_p): Support property values that are
15239 lists with the argument STRING its top-level element.
15240 (display_prop_string_p): Fix the condition for processing a
15241 property that is a list to be consistent with handle_display_spec.
15242 (handle_display_spec): New function, refactored from the
15243 last portion of handle_display_prop.
15244 (compute_display_string_pos): Accept additional argument
15245 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
15246 value of a `display' property is a "replacing spec".
15247 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
15248 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
15249 the display property, but just return a value indicating whether
15250 the display property will replace the characters it covers.
15251 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
15252 frame_window_p members of struct bidi_it.
15253 (compute_display_string_pos, compute_display_string_end):
15255 (push_it): Accept second argument POSITION, where pop_it should
15256 jump to continue iteration.
15257 (reseat_1): Initialize bidi_it.disp_pos.
15259 * keyboard.c (adjust_point_for_property): Adjust the call to
15260 display_prop_intangible_p to its new signature.
15262 * dispextern.h (struct bidi_it): New member frame_window_p.
15263 (bidi_init_it): Update prototypes.
15264 (display_prop_intangible_p): Update prototype.
15265 (compute_display_string_pos, compute_display_string_end):
15266 Declare prototypes.
15267 (struct bidi_it): New members nchars and disp_pos. ch_len is now
15270 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
15272 Malloc failure behavior now depends on size of allocation.
15273 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
15274 * lisp.h: Change signatures accordingly.
15275 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
15276 All callers changed. (Bug#8762)
15278 * gnutls.c: Use Emacs's memory allocators.
15279 Without this change, the gnutls library would invoke malloc etc.
15280 directly, which causes problems on non-SYNC_INPUT hosts, and which
15281 runs afoul of improving memory_full behavior. (Bug#8761)
15282 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
15283 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
15284 xfree instead of the default malloc, realloc, free.
15285 (Fgnutls_boot): No need to check for memory allocation failure,
15286 since xmalloc does that for us.
15288 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
15289 * category.c (hash_get_category_set):
15290 * ccl.c (ccl_driver):
15291 * charset.c (Fdefine_charset_internal):
15292 * charset.h (struct charset.hash_index):

15294 (composition_gstring_put_cache):
15295 * composite.h (struct composition.hash_index):

15302 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
15303 (Fsxhash, Fgethash, Fputhash, Fmaphash):
15304 * image.c (make_image, search_image_cache, lookup_image)
15305 (xpm_put_color_table_h):
15306 * lisp.h (struct Lisp_Hash_Table):
15307 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
15308 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
15309 for hashes and hash indexes, instead of 'unsigned' and 'int'.
15310 * alloc.c (allocate_vectorlike):
15311 Check for overflow in vector size calculations.
15312 * ccl.c (ccl_driver):
15313 Check for overflow when converting EMACS_INT to int.
15314 * fns.c, image.c: Remove unnecessary static decls that would otherwise
15315 need to be updated by these changes.
15316 * fns.c (make_hash_table, maybe_resize_hash_table):
15317 Check for integer overflow with large hash tables.
15318 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
15319 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
15320 (SXHASH_REDUCE): New macro.
15321 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
15322 Use it instead of discarding useful hash info with large hash values.
15323 (sxhash_float): New function.
15324 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
15325 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
15326 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
15327 Rewrite to use FIXNUM_BITS, as this simplifies things.
15328 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
15329 Adjust signatures to match updated version of code.
15330 (consing_since_gc): Now EMACS_INT, since a single hash table can
15331 use more than INT_MAX bytes.
15333 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
15335 Make it possible to build with GCC-4.6+ -O2 -flto.
15337 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
15339 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
15341 * minibuf.c (get_minibuffer, read_minibuf_unwind):
15342 Call minibuffer-inactive-mode.
15344 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
15346 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
15347 Update dependencies.
15349 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
15351 * data.c (init_data): Remove code for UTS, this system is not
15354 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
15356 Don't force ./temacs to start in terminal mode.
15358 * frame.c (make_initial_frame): Initialize faces in all cases, not
15359 only when CANNOT_DUMP is defined.
15360 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
15362 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
15364 * dispnew.c (add_window_display_history): Use const for the string
15365 pointer. Remove declaration, not needed.
15367 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
15369 Use 'inline', not 'INLINE'.
15370 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
15371 * alloc.c, fontset.c (INLINE): Remove.
15372 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
15373 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
15374 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
15375 * gmalloc.c (register_heapinfo): Use inline unconditionally.
15376 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
15378 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
15380 Make it possible to run ./temacs.
15382 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
15383 syms_of_callproc does the same thing. Remove test for
15384 "initialized", do it in the caller.
15385 * emacs.c (main): Avoid calling set_initial_environment when dumping.
15387 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
15389 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
15390 (read_minibuf): Use get_minibuffer.
15391 (syms_of_minibuf): Use DEFSYM.
15392 (Qmetadata): New var.
15393 * data.c (Qbuffer): Don't make it static.
15394 (syms_of_data): Use DEFSYM.
15396 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
15398 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
15399 (CCL_CODE_MIN): New macro.
15401 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
15403 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
15405 * eval.c (Qdebug): Now static.
15406 * lisp.h (Qdebug): Remove decl. This reverts a part of the
15407 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
15408 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
15410 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
15412 * image.c: Various fixes to ImageMagick code comments.
15413 (Fimagemagick_types): Doc fix.
15415 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
15417 Minor fixes prompted by GCC 4.6.0 warnings.
15419 * xselect.c (converted_selections, conversion_fail_tag): Now static.
15421 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
15422 (x_clipboard_manager_save_all): Move extern decl to ...
15423 * xterm.h: ... here, so that it can be checked for consistency.
15425 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
15427 * xselect.c (x_clipboard_manager_save_frame)
15428 (x_clipboard_manager_save_all): New functions.
15429 (Fx_clipboard_manager_save): Lisp function deleted.
15431 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
15432 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
15434 * xterm.h: Update prototype.
15436 2011-05-28 William Xu <william.xwl@gmail.com>
15438 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
15439 exiting (Bug#8239).
15441 2011-05-28 Jim Meyering <meyering@redhat.com>
15443 Avoid a sign-extension bug in crypto_hash_function.
15444 * fns.c (to_uchar): Define.
15445 (crypto_hash_function): Use it to convert some newly-signed
15446 variables to unsigned, to avoid sign-extension bugs. For example,
15447 without this change, (md5 "truc") would evaluate to
15448 45723a2aff78ff4fff7fff1114760e62 rather than the expected
15449 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
15450 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
15452 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
15454 Integer overflow fixes.
15456 * dbusbind.c: Serial number integer overflow fixes.
15457 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
15458 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
15459 to hold a serial number that is too large for a fixnum.
15460 (Fdbus_method_return_internal, Fdbus_method_error_internal):
15461 Check for serial numbers out of range. Decode any serial number
15462 that was so large that it became a float. (Bug#8722)
15464 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
15465 (Fdbus_call_method, Fdbus_call_method_asynchronously):
15466 Use XFASTINT rather than XUINT when numbers are nonnegative.
15467 (xd_append_arg, Fdbus_method_return_internal):
15468 (Fdbus_method_error_internal): Likewise. Also, for unsigned
15469 arguments, check that Lisp number is nonnegative, rather than
15470 silently wrapping negative numbers around. (Bug#8722)
15471 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
15474 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
15476 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
15478 ccl: Add integer overflow checks.
15479 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
15480 (IN_INT_RANGE): New macros.
15481 (ccl_driver): Use them to check for integer overflow when
15482 decoding a CCL program. Many of the new checks are whether XINT (x)
15483 fits in int; it doesn't always, on 64-bit hosts. The new version
15484 doesn't catch all possible integer overflows, but it's an
15485 improvement. (Bug#8719)
15487 * alloc.c (make_event_array): Use XINT, not XUINT.
15488 There's no need for unsigned here.
15490 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
15491 This follows up to the 2011-05-06 change that substituted uintptr_t
15492 for EMACS_INT. This case wasn't caught back then.
15494 Rework Fformat to avoid integer overflow issues.
15495 * editfns.c: Include <float.h> unconditionally, as it's everywhere
15496 now (part of C89). Include <verify.h>.
15497 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
15498 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
15499 (Fformat): Avoid the prepass trying to compute sizes; it was only
15500 approximate and thus did not catch overflow reliably. Instead, walk
15501 through the format just once, formatting and computing sizes as we go,
15502 checking for integer overflow at every step, and allocating a larger
15503 buffer as needed. Keep track separately whether the format is
15504 multibyte. Keep only the most-recently calculated precision, rather
15505 than them all. Record whether each argument has been converted to
15506 string. Use EMACS_INT, not int, for byte and char and arg counts.
15507 Support field widths and precisions larger than INT_MAX. Avoid
15508 sprintf's undefined behavior with conversion specifications such as %#d
15509 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
15510 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
15511 formatting out-of-range floating point numbers with int
15512 formats. (Bug#8668)
15514 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
15516 * data.c: Avoid integer truncation in expressions involving floats.
15517 * data.c: Include <intprops.h>.
15518 (arith_driver): When there's an integer overflow in an expression
15519 involving floating point, convert the integers to floating point
15520 so that the resulting value does not suffer from catastrophic
15521 integer truncation. For example, on a 64-bit host (* 4
15522 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
15523 Do not rely on undefined behavior after integer overflow.
15525 merge count_size_as_multibyte, parse_str_to_multibyte
15526 * character.c, character.h (count_size_as_multibyte):
15527 Rename from parse_str_to_multibyte; all uses changed.
15528 Check for integer overflow.
15529 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
15530 since it's now a duplicate of the other. This is more of
15531 a character than a buffer op, so better that it's in character.c.
15532 * fns.c, print.c: Adjust to above changes.
15534 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
15536 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
15538 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
15540 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
15541 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
15542 (x_clipboard_manager_save): Now static.
15543 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
15545 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
15546 (crypto_hash_function): Now static.
15547 Fix pointer signedness problems. Avoid unnecessary initializations.
15549 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
15551 * termhooks.h (Vselection_alist): Make it terminal-local.
15553 * terminal.c (create_terminal): Initialize it.
15555 * xselect.c: Support for clipboard managers.
15556 (Vselection_alist): Move to termhooks.h as terminal-local var.
15557 (LOCAL_SELECTION): New macro.
15558 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
15559 (symbol_to_x_atom): Remove gratuitous arg.
15560 (x_handle_selection_request, lisp_data_to_selection_data)
15561 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
15562 (x_own_selection, x_get_local_selection, x_convert_selection):
15563 New arg, specifying work frame. Use terminal-local Vselection_alist.
15564 (some_frame_on_display): Delete unused function.
15565 (Fx_own_selection_internal, Fx_get_selection_internal)
15566 (Fx_disown_selection_internal, Fx_selection_owner_p)
15567 (Fx_selection_exists_p): New optional frame arg.
15568 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
15569 (x_handle_selection_clear): Don't treat other terminals with the
15570 same keyboard specially. Use the terminal-local Vselection_alist.
15571 (x_clear_frame_selections): Use Frun_hook_with_args.
15573 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
15575 * xterm.h: Add support for those atoms.
15577 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
15579 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
15580 (converted_selections, conversion_fail_tag): New global variables.
15581 (x_selection_request_lisp_error): Free the above.
15582 (x_get_local_selection): Remove unnecessary code.
15583 (x_reply_selection_request): Args changed; handle arbitrary array
15584 of converted selections stored in converted_selections.
15585 Separate the XChangeProperty and SelectionNotify steps.
15586 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
15587 (x_convert_selection): New function.
15588 (x_handle_selection_event): Simplify.
15589 (x_get_foreign_selection): Don't ignore incoming requests while
15590 waiting for an answer; this will fail when we implement
15591 SAVE_TARGETS, and seems unnecessary anyway.
15592 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
15593 (Vx_sent_selection_functions): Doc fix.
15595 2011-05-26 Leo Liu <sdl.web@gmail.com>
15597 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
15599 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15601 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
15603 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
15604 for fringe update if it has periodic bitmap.
15605 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
15606 and fringe_bitmap_periodic_p.
15608 * fringe.c (get_fringe_bitmap_data): New function.
15609 (draw_fringe_bitmap_1, update_window_fringes): Use it.
15610 (update_window_fringes): Record periodicity of fringe bitmap in glyph
15611 row. Mark glyph row for fringe update if periodicity changed.
15613 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
15614 for fringe update unless it has periodic bitmap.
15616 2011-05-25 Kenichi Handa <handa@m17n.org>
15618 * xdisp.c (get_next_display_element): Set correct it->face_id for
15619 a static composition.
15621 2011-05-24 Leo Liu <sdl.web@gmail.com>
15624 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
15626 * fns.c (crypto_hash_function, Fsha1): New function.
15627 (Fmd5): Use crypto_hash_function.
15628 (syms_of_fns): Add Ssha1.
15630 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
15632 * gnutls.c: Remove unused macros.
15633 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
15634 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
15635 Remove macros that are defined and never used.
15636 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
15638 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
15640 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
15641 (Fx_get_selection_internal): Minor cleanup.
15642 (Fx_own_selection_internal): Rename arguments for consistency with
15645 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
15647 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
15649 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
15651 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
15653 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15655 * dispnew.c (scrolling_window): Don't exclude the case that the
15656 last enabled row in the desired matrix touches the bottom boundary.
15658 2011-05-21 Glenn Morris <rgm@gnu.org>
15660 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
15661 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
15662 and add some more files.
15664 2011-05-20 Eli Zaretskii <eliz@gnu.org>
15666 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
15667 report_file_error introduced by the change from 2011-05-07.
15669 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
15671 * systime.h (Time): Define only if emacs is defined.
15672 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
15673 where the include path doesn't have X11/X.h by default. See
15674 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
15676 2011-05-20 Kenichi Handa <handa@m17n.org>
15678 * composite.c (find_automatic_composition): Fix previous change.
15680 2011-05-20 Glenn Morris <rgm@gnu.org>
15682 * lisp.mk: New file, split from Makefile.in.
15683 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
15684 (shortlisp): Remove.
15685 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
15687 2011-05-19 Glenn Morris <rgm@gnu.org>
15689 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
15690 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
15691 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
15692 (lisp): Set the order to that of loadup.el.
15693 (shortlisp): Make it a copy of $lisp.
15694 (SOME_MACHINE_LISP): Remove.
15695 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
15696 Use just $shortlisp, not $SOME_MACHINE_LISP too.
15698 2011-05-18 Kenichi Handa <handa@m17n.org>
15700 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
15701 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
15702 (find_automatic_composition): Mostly rewrite for efficiency.
15704 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
15706 * makefile.w32-in: Update dependencies.
15708 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
15710 * menu.c: Include limits.h (fixes the MS-Windows build broken by
15711 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
15713 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
15715 Fix some integer overflow issues, such as string length overflow.
15717 * insdel.c (count_size_as_multibyte): Check for string overflow.
15719 * character.c (lisp_string_width): Check for string overflow.
15720 Use EMACS_INT, not int, for string indexes and lengths; in
15721 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
15722 the resulting string length overflows an EMACS_INT; instead,
15723 report a string overflow if no precision given. When checking for
15724 precision exhaustion, use a check that cannot possibly have
15725 integer overflow. (Bug#8675)
15726 * character.h (lisp_string_width): Adjust to new signature.
15728 * alloc.c (string_overflow): New function.
15729 (Fmake_string): Use it. This doesn't change behavior, but saves
15730 a few bytes and will simplify future changes.
15731 * character.c (string_escape_byte8): Likewise.
15732 * lisp.h (string_overflow): New decl.
15734 Fixups, following up to the user-interface timestamp change.
15735 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
15736 for UI timestamps, instead of unsigned long.
15737 * msdos.c (mouse_get_pos): Likewise.
15738 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
15739 * w32gui.h (Time): Define by including "systime.h" rather than by
15740 declaring it ourselves. (Bug#8664)
15742 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
15743 * image.c (clear_image_cache): Likewise.
15745 * term.c (term_mouse_position): Don't assume time_t wraparound.
15747 Be more systematic about user-interface timestamps.
15748 Before, the code sometimes used 'Time', sometimes 'unsigned long',
15749 and sometimes 'EMACS_UINT', to represent these timestamps.
15750 This change causes it to use 'Time' uniformly, as that's what X uses.
15751 This makes the code easier to follow, and makes it easier to catch
15752 integer overflow bugs such as Bug#8664.
15753 * frame.c (Fmouse_position, Fmouse_pixel_position):
15754 Use Time, not unsigned long, for user-interface timestamps.
15755 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
15756 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
15757 * keyboard.h (last_event_timestamp): Likewise.
15758 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
15759 * menu.h (xmenu_show): Likewise.
15760 * term.c (term_mouse_position): Likewise.
15761 * termhooks.h (struct input_event.timestamp): Likewise.
15762 (struct terminal.mouse_position_hook): Likewise.
15763 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
15764 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
15765 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
15766 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
15767 what it was before.
15768 * menu.h, termhooks.h: Include "systime.h", for Time.
15770 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
15771 Don't assume that the difference between two unsigned long values
15772 can fit into an integer. At this point, we know button_down_time
15773 <= event->timestamp, so the difference must be nonnegative, so
15774 there's no need to cast the result if double-click-time is
15775 nonnegative, as it should be; check that it's nonnegative, just in
15776 case. This bug is triggered when events are more than 2**31 ms
15777 apart (about 25 days). (Bug#8664)
15779 * xselect.c (last_event_timestamp): Remove duplicate decl.
15780 (x_own_selection): Remove needless cast to unsigned long.
15782 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
15783 that always fit in int. Use a sentinel instead of a counter, to
15784 avoid a temp and to allay GCC's concerns about possible int overflow.
15785 * frame.h (struct frame): Use int for menu_bar_items_used
15786 instead of EMACS_INT, since it always fits in int.
15788 * menu.c (grow_menu_items): Check for int overflow.
15790 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
15792 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
15793 Before, the code was not consistent. These values cannot exceed
15794 2**31 - 1 so there's no need to make them unsigned.
15795 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
15796 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
15797 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
15799 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
15801 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
15802 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
15803 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
15804 presumably because the widths might not match.
15806 * window.c (size_window): Avoid needless test at loop start.
15808 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
15810 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
15812 2011-05-12 Drew Adams <drew.adams@oracle.com>
15814 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
15816 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15818 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
15819 `width' to `bar_area_x' and `bar_area_width', respectively.
15820 (x_scroll_run): Take account of fringe background extension.
15822 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
15823 Rename local vars `left' and `width' to `bar_area_x' and
15824 `bar_area_width', respectively.
15825 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
15826 background extension.
15828 2011-05-10 Jim Meyering <meyering@redhat.com>
15830 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
15832 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
15834 * image.c (Finit_image_library): Return t for built-in image types,
15835 like pbm and xbm. (Bug#8640)
15837 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
15839 * w32menu.c (set_frame_menubar): Fix submenu allocation.
15841 2011-05-07 Eli Zaretskii <eliz@gnu.org>
15843 * w32console.c (Fset_screen_color): Doc fix.
15844 (Fget_screen_color): New function.
15845 (syms_of_ntterm): Defsubr it.
15847 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
15848 unlink the temporary file if Fcall_process didn't create it in the
15850 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
15851 child process will be redirected to a file specified with `:file'.
15852 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
15853 cue to call_process_cleanup not to close that handle.
15855 2011-05-07 Ben Key <bkey76@gmail.com>
15857 * makefile.w32-in: The bootstrap-temacs rule now makes use of
15858 one of two shell specific rules, either bootstrap-temacs-CMD or
15859 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
15860 to the previous implementation of the bootstrap-temacs rule.
15861 The bootstrap-temacs-CMD rule is similar to the previous
15862 implementation of the bootstrap-temacs rule except that it
15863 makes use of the ESC_CFLAGS variable instead of the CFLAGS
15866 These changes, along with some changes to nt/configure.bat,
15867 nt/gmake.defs, and nt/nmake.defs, are required to extend my
15868 earlier fix to add support for --cflags and --ldflags options
15869 that include quotes so that it works whether make uses cmd or
15872 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
15874 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
15875 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
15877 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
15878 a string. Handle both cases.
15879 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
15880 (Fdbus_register_method): Use Qinvalid_function.
15882 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
15884 * makefile.w32-in: Update dependencies.
15885 (LISP_H): Add inttypes.h and stdin.h.
15886 (PROCESS_H): Add unistd.h.
15888 2011-05-06 Eli Zaretskii <eliz@gnu.org>
15890 * lread.c: Include limits.h (fixes the MS-Windows build broken by
15891 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
15893 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
15895 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
15897 * term.c (vfatal): Remove stray call to va_end.
15898 It's not needed and the C Standard doesn't allow it here anyway.
15900 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
15901 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
15903 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
15906 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
15908 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
15910 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
15912 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
15914 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
15916 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
15917 * charset.c (Fdefine_charset_internal): Don't initialize
15918 charset.code_space[15]. The value was garbage, on hosts with
15919 32-bit int (Bug#8600).
15921 * lread.c (read_integer): Be more consistent with string-to-number.
15922 Use string_to_number to do the actual conversion; this avoids
15923 rounding errors and fixes some other screwups. Without this fix,
15924 for example, #x1fffffffffffffff was misread as -2305843009213693952.
15925 (digit_to_number): Move earlier, for benefit of read_integer.
15926 Return -1 if the digit is out of range for the base, -2 if it is
15927 not a digit in any supported base. (Bug#8602)
15929 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
15931 * dispnew.c (scrolling_window): Return 1 if we scrolled,
15932 to match comment at start of function. This also removes a
15933 GCC warning about overflow in a 32+64-bit port.
15935 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
15937 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
15938 Reported by Stefan Monnier in
15939 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
15940 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
15941 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
15943 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
15944 (EMACS_UINTPTR): Likewise, with uintptr_t.
15946 * lisp.h: Prefer 64-bit EMACS_INT if available.
15947 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
15948 on 32-bit hosts that have 64-bit int, so that they can access
15950 However, temporarily disable this change unless the temporary
15951 symbol WIDE_EMACS_INT is defined.
15953 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
15955 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
15956 This removes an assumption that EMACS_INT and long are the same
15957 width as pointers. The assumption is true for Emacs porting targets
15958 now, but we want to make other targets possible.
15959 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
15960 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
15961 In the rest of the code, change types of integers that hold casted
15962 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
15963 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
15964 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
15965 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
15966 No need to cast type when ORing.
15967 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
15968 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
15969 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
15970 assume EMACS_INT is the same width as char *.
15971 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
15972 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
15973 Remove no-longer-needed casts.
15974 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
15975 (xg_tool_bar_help_callback, xg_make_tool_item):
15976 Use EMACS_INTPTR to hold an integer
15977 that will be cast to void *; this can avoid a GCC warning
15978 if EMACS_INT is not the same width as void *.
15979 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
15980 * xdisp.c (display_echo_area_1, resize_mini_window_1):
15981 (current_message_1, set_message_1):
15982 Use a local to convert to proper width without a cast.
15983 * xmenu.c (dialog_selection_callback): Likewise.
15985 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
15986 Also, don't assume VALBITS / RAND_BITS is less than 5,
15987 and don't rely on undefined behavior when shifting a 1 left into
15989 * lisp.h (get_random): Change signature to match.
15991 * lread.c (hash_string): Use size_t, not int, for hash computation.
15992 Normally we prefer signed values; but hashing is special, because
15993 it's better to use unsigned division on hash table sizes so that
15994 the remainder is nonnegative. Also, size_t is the natural width
15995 for hashing into memory. The previous code used 'int', which doesn't
15996 retain enough info to hash well into very large tables.
15997 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
15999 * dbusbind.c: Don't possibly lose pointer info when converting.
16000 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
16001 Use XPNTR rather than XHASH, so that the high-order bits of
16002 the pointer aren't lost when converting through void *.
16004 * eval.c (Fautoload): Don't double-shift a pointer.
16006 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
16008 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
16010 * gnutls.c (DEF_GNUTLS_FN):
16011 * image.c (DEF_IMGLIB_FN): Make function pointers static.
16013 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
16015 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
16018 2011-05-05 Eli Zaretskii <eliz@gnu.org>
16020 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
16021 New version that can reserve upto 2GB of heap space.
16023 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
16025 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
16027 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
16029 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
16030 `gnutls_certificate_set_x509_key_file'.
16032 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
16034 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
16035 Update dependencies.
16037 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
16039 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
16040 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
16041 Remove unused parameter `fildes'.

16086 Initialize and staticpro them.
16087 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
16089 * process.c: Include lisp.h before w32.h, not after.
16090 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
16091 instead of gnutls_record_check_pending.
16093 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
16095 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
16097 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options

16143 rather than `XVECTOR (FOO)->size'.
16145 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
16146 inttypes.h, as a gnulib replacement is used if it not available in
16149 2011-04-21 Eli Zaretskii <eliz@gnu.org>
16151 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
16152 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
16153 of MOST_POSITIVE_FIXNUM. (Bug#8528)

16156 will grow beyond MOST_POSITIVE_FIXNUM.
16157 (decode_coding_emacs_mule): Abort if there isn't enough place in

16161 charbuf for the composition carryover bytes.
16163 2011-04-21 Eli Zaretskii <eliz@gnu.org>
16165 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
16166 aborting when %lld or %lll format is passed.
16167 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
16168 %llo or %llx format is passed. (Bug#8545)
16170 * window.c (window_scroll_line_based): Use a marker instead of
16171 simple variables to record original value of point. (Bug#7952)
16173 * doprnt.c (doprnt): Fix the case where a multibyte sequence
16174 produced by %s or %c overflows available buffer space. (Bug#8545)
16176 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
16178 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
16179 (SIZE_MAX): Move defn after all includes, as they might #define it.
16181 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
16183 * w32.c (init_environment): Warn about defaulting HOME to C:\.
16185 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
16187 * keyboard.c (Qdelayed_warnings_hook): Define.
16188 (command_loop_1): Run `delayed-warnings-hook'
16189 if Vdelayed_warnings_list is non-nil.
16190 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
16191 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
16193 2011-04-28 Eli Zaretskii <eliz@gnu.org>
16195 * doprnt.c (doprnt): Don't return value smaller than the buffer
16196 size if the message was truncated. (Bug#8545).
16198 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
16200 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
16201 (Fx_window_property): #if-0 the whole functions, not just the bodies.
16203 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
16205 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
16207 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
16209 * makefile.w32-in: Update dependencies.
16211 2011-04-27 Eli Zaretskii <eliz@gnu.org>
16213 Improve `doprnt' and its usage. (Bug#8545)
16214 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
16215 `format_end'. Remove support for %l as a conversion specifier.
16216 Don't use xrealloc. Improve diagnostics when the %l size modifier
16217 is used. Update the commentary.
16219 * eval.c (verror): Simplify calculation of size_t.
16221 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
16224 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
16226 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
16229 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
16231 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
16232 This makes this file independent of the recent pseudovector change.
16234 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
16236 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
16238 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
16239 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
16240 Remove unused local.
16241 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
16243 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
16244 GCC 4.6.0 optimizes based on type-based alias analysis.
16245 For example, if b is of type struct buffer * and v of type struct
16246 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
16247 != &v->size, and therefore "v->size = 1; b->size = 2; return
16248 v->size;" must therefore return 1. This assumption is incorrect
16249 for Emacs, since it type-puns struct Lisp_Vector * with many other
16250 types. To fix this problem, this patch adds a new type struct
16251 vectorlike_header that documents the constraints on layout of vectors
16252 and pseudovectors, and helps optimizing compilers not get fooled
16253 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
16254 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
16255 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
16257 (XSETPVECTYPE): Rewrite in terms of new macro.
16258 (XSETPVECTYPESIZE): New macro, specifying both type and size.
16259 This is a bit clearer, and further avoids the possibility of
16260 undesirable aliasing.
16261 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
16262 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
16263 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
16264 since Lisp_Subr is a special case (no "next" field).
16265 (ASIZE): Now uses header.size rather than size.
16266 All previous uses of XVECTOR (foo)->size replaced to use this macro,
16267 to avoid the hassle of writing XVECTOR (foo)->header.size.
16268 (struct vectorlike_header): New type.
16269 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
16270 object, to help avoid aliasing.
16271 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
16272 (SUBRP): Likewise, since Lisp_Subr is a special case.
16273 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
16274 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
16275 (struct Lisp_Hash_Table): Combine first two members into a single
16276 struct vectorlike_header member. All uses of "size" and "next" members
16277 changed to be "header.size" and "header.next".
16278 * buffer.h (struct buffer): Likewise.
16279 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
16280 * frame.h (struct frame): Likewise.
16281 * process.h (struct Lisp_Process): Likewise.
16282 * termhooks.h (struct terminal): Likewise.
16283 * window.c (struct save_window_data, struct saved_window): Likewise.
16284 * window.h (struct window): Likewise.
16285 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
16286 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
16287 * buffer.c (init_buffer_once): Likewise.
16288 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
16290 * process.c (Fformat_network_address): Use local var for size,
16293 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
16295 Make the Lisp reader and string-to-float more consistent (Bug#8525)
16296 * data.c (atof): Remove decl; no longer used or needed.
16297 (digit_to_number): Move to lread.c.
16298 (Fstring_to_number): Use new string_to_number function, to be
16299 consistent with how the Lisp reader treats infinities and NaNs.
16300 Do not assume that floating-point numbers represent EMACS_INT
16301 without losing information; this is not true on most 64-bit hosts.
16302 Avoid double-rounding errors, by insisting on integers when
16303 parsing non-base-10 numbers, as the documentation specifies.
16304 * lisp.h (string_to_number): New decl, replacing ...
16305 (isfloat_string): Remove.
16306 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
16307 (read1): Do not accept +. and -. as integers; this
16308 appears to have been a coding error. Similarly, do not accept
16309 strings like +-1e0 as floating point numbers. Do not report
16310 overflow for integer overflows unless the base is not 10 which
16311 means we have no simple and reliable way to continue.
16312 Break out the floating-point parsing into a new
16313 function string_to_number, so that Fstring_to_number parses
16314 floating point numbers consistently with the Lisp reader.
16315 (digit_to_number): Move here from data.c. Make it static inline.
16316 (E_CHAR, EXP_INT): Remove, replacing with ...
16317 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
16318 (string_to_number): New function, replacing isfloat_string.
16319 This function checks for valid syntax and produces the resulting
16320 Lisp float number too. Rework it so that string-to-number
16321 no longer mishandles examples like "1.0e+". Use strtoumax,
16322 so that overflow for non-base-10 numbers is reported only when
16323 there's no portable and simple way to convert to floating point.
16325 * textprop.c (set_text_properties_1): Rewrite for clarity,
16326 and to avoid GCC warning about integer overflow.
16328 * intervals.h (struct interval): Use EMACS_INT for members
16329 where EMACS_UINT might cause problems. See
16330 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
16331 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
16332 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
16334 (offset_intervals): Tell GCC not to worry about length overflow
16335 when negating a negative length.
16337 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
16338 (overrun_check_free): Likewise.
16340 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
16341 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
16344 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
16345 (gnutls_make_error): Rename local to avoid shadowing.
16346 (gnutls_emacs_global_deinit): ifdef out; not used.
16347 (Fgnutls_boot): Use const for pointer to readonly storage.
16348 Comment out unused local. Fix pointer signedness problems.
16350 * lread.c (openp): Don't stuff size_t into an 'int'.
16351 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
16352 about possible signed overflow.
16354 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
16355 (GDK_KEY_g): Don't define if already defined.
16356 (xg_prepare_tooltip): Avoid pointer signedness problem.
16357 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
16359 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
16360 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
16362 * xfns.c (Fx_window_property): Simplify a bit,
16363 to make a bit faster and to avoid GCC 4.6.0 warning.
16364 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
16366 * fns.c (internal_equal): Don't assume size_t fits in int.
16368 * alloc.c (compact_small_strings): Tighten assertion a little.
16370 Replace pEd with more-general pI, and fix some printf arg casts.
16371 * lisp.h (pI): New macro, generalizing old pEd macro to other
16372 conversion specifiers. For example, use "...%"pI"d..." rather
16373 than "...%"pEd"...".
16374 (pEd): Remove. All uses replaced with similar uses of pI.
16375 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
16376 * alloc.c (check_pure_size): Don't overflow by converting size to int.
16377 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
16378 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
16379 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
16380 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
16381 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
16383 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
16384 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
16385 * print.c (safe_debug_print, print_object): Likewise.
16386 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
16388 Use pI instead of if-then-else-abort. Use %p to avoid casts,
16389 avoiding the 0 flag, which is not portable.
16390 * process.c (Fmake_network_process): Use pI to avoid cast.
16391 * region-cache.c (pp_cache): Likewise.
16392 * xdisp.c (decode_mode_spec): Likewise.
16393 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
16394 behavior on 64-bit hosts with printf arg.
16395 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
16396 (x_stop_queuing_selection_requests): Likewise.
16397 (x_get_window_property): Don't truncate byte count to an 'int'
16400 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
16401 here, since it parses constructs like leading '-' and spaces,
16402 which are not wanted; and it overflows with large numbers.
16403 Instead, simply match F[0-9]+, which is what is wanted anyway.
16405 * alloc.c: Remove unportable assumptions about struct layout.
16406 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
16407 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
16408 (allocate_vectorlike, make_pure_vector): Use the new macros,
16409 plus offsetof, to remove unportable assumptions about struct layout.
16410 These assumptions hold on all porting targets that I know of, but
16411 they are not guaranteed, they're easy to remove, and removing them
16412 makes further changes easier.
16414 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
16415 This doesn't fix a bug but makes the code clearer.
16416 (string_overrun_cookie): Now const. Use initializers that
16417 don't formally overflow signed char, to avoid warnings.
16418 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
16419 can cause Emacs to crash when string overrun checking is enabled.
16420 (allocate_buffer): Don't assume sizeof (struct buffer) is a
16421 multiple of sizeof (EMACS_INT); it need not be, if
16422 alignof(EMACS_INT) < sizeof (EMACS_INT).
16423 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
16425 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
16427 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
16429 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
16431 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
16432 supposed to be handshaking. (Bug#8556)
16433 Reported by Paul Eggert <eggert@cs.ucla.edu>.
16435 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
16437 * lisp.h (Qdebug): List symbol.
16438 * eval.c (Qdebug): Restore global linkage.
16439 * keyboard.c (debug-on-event): New variable.
16440 (handle_user_signal): Break into debugger when debug-on-event
16441 matches the current signal symbol.
16443 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
16445 * alloc.c (check_sblock, check_string_bytes)
16446 (check_string_free_list): Convert to standard C.
16448 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
16450 * w32.c (emacs_gnutls_push): Fix typo.
16452 2011-04-25 Eli Zaretskii <eliz@gnu.org>
16454 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
16455 "cast to pointer from integer of different size".
16457 Improve doprnt and its use in verror. (Bug#8545)
16458 * doprnt.c (doprnt): Document the set of format control sequences
16459 supported by the function. Use SAFE_ALLOCA instead of always

16956 * lisp.h (echoing): Remove decl.
16957 (force_auto_save_soon): Declare only if SIGDANGER.
16958 * xdisp.c (redisplay_window): Simplify code, to make it more
16959 obvious that ignore_mouse_drag_p is not accessed if !defined
16960 USE_GTK && !defined HAVE_NS.
16962 * intervals.c: Make symbols static if they're not exported.

16967 * insdel.c: Make symbols static if they're not exported.
16968 However, leave prepare_to_modify_buffer alone. It's never
16969 called from outside this function, but that appears to be a bug.

17000 * font.c (font_close_object): Now static.
17001 * font.h (font_close_object): Remove.
17002 * fontset.c (FONTSET_OBJLIST): Remove.

17005 * fontset.h (face_suitable_for_char_p): Remove decl.
17006 * xfaces.c (face_at_string_position):
17007 Use FACE_SUITABLE_FOR_ASCII_CHAR_P, not FACE_SUITABLE_FOR_CHAR_P,
17008 since 0 is always ASCII.
17010 * fns.c (weak_hash_tables): Now static.

17031 * editfns.c, lisp.h (get_operating_system_release): Remove.
17032 * process.c (init_process) [DARWIN_OS]: Do it inline, as it is not
17033 worth the hassle of breaking this out.
17035 * xterm.c: Make symbols static if they're not exported.
17036 (x_raise_frame, x_lower_frame, x_wm_set_window_state):

17150 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.

17156 alloc.c: Import and export fewer symbols, and remove unused items.
17157 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
17159 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
17160 it's not optimized away by whole-program optimization.
17161 (message_enable_multibyte, free_misc): Remove.
17162 (catchlist, handlerlist, mark_backtrace):
17163 Declare only if BYTE_MARK_STACK.

17173 (mark_backtrace): Define only if BYTE_MARK_STACK.
17174 * xdisp.c (message_enable_multibyte): Now static.
17176 Declare Lisp_Object Q* variables to be 'static' if not exported.
17177 This makes it easier for human readers (and static analyzers)
17178 to see whether these variables are used from other modules.
17179 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:

17190 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
17192 * lisp.h (DEFINE_FUNC): Make sname 'static'.
17194 Make Emacs functions such as Fatom 'static' by default.
17195 This makes it easier for human readers (and static analyzers)
17196 to see whether these functions can be called from other modules.
17197 DEFUN now defines a static function. To make the function external
17198 so that it can be used in other C modules, use the new macro DEFUE.
17199 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
17200 (Finit_image_library):
17201 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
17202 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
17203 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
17204 Remove decls, since these functions are now static.
17205 (Funintern, Fget_internal_run_time): New decls, since these functions
17206 were already external.
17208 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
17209 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

17215 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
17216 Mark functions with DEFUE instead of DEFUN,
17217 if they are used in other modules.
17218 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
17219 decls for now-static functions.
17220 * buffer.h (Fdelete_overlay): Remove decl.
17221 * callproc.c (Fgetenv_internal): Mark as internal.

17229 * fileio.c (Fmake_symbolic_link): New forward static decl.
17230 * image.c (Finit_image_library): New forward static decl.
17231 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
17232 * intervals.h (Fprevious_property_change):
17233 (Fremove_list_of_text_properties): Remove decls.
17234 * keyboard.c (Fthis_command_keys): Remove decl.
17235 (Fcommand_execute): New forward static decl.

17251 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
17253 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
17256 2011-04-13 Eli Zaretskii <eliz@gnu.org>
17258 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
17259 when at ZV. (Bug#8487)
17261 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
17263 * charset.c (Fclear_charset_maps): Use xfree instead of free.
17265 * keyboard.c (parse_tool_bar_item): Likewise.
17266 * sound.c (sound_cleanup, alsa_close): Likewise.
17267 * termcap.c (tgetent): Likewise.

17269 * xsettings.c (read_and_apply_settings): Likewise.
17271 * alloc.c (overrun_check_malloc, overrun_check_realloc)
17272 (overrun_check_free): Protoize.
17274 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
17276 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
17277 since callers should never pass a negative size.
17278 Change the signature to match that of plain 'read' and 'write'; see
17279 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
17280 * lisp.h: Update prototypes of emacs_write and emacs_read.
17282 2011-04-11 Eli Zaretskii <eliz@gnu.org>
17284 * xdisp.c (redisplay_window): Don't try to determine the character
17285 position of the scroll margin if the window start point w->startp
17286 is outside the buffer's accessible region. (Bug#8468)
17288 2011-04-10 Eli Zaretskii <eliz@gnu.org>
17290 Fix write-region and its subroutines for buffers > 2GB.
17291 * fileio.c (a_write, e_write): Modify declaration of arguments and
17292 local variables to support buffers larger than 2GB.
17293 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
17295 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
17296 argument, local variables, and return value.
17298 * lisp.h: Update prototypes of emacs_write and emacs_read.
17300 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
17302 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
17304 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
17306 Fix more problems found by GCC 4.6.0's static checks.
17308 * xdisp.c (vmessage): Use a better test for character truncation.
17310 * charset.c (load_charset_map): <, not <=, for optimization,
17311 and to avoid potential problems with integer overflow.
17312 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
17313 * casetab.c (set_identity, shuffle): Likewise.
17314 * editfns.c (Fformat): Likewise.
17315 * syntax.c (skip_chars): Likewise.
17317 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
17318 This also lets GCC 4.6.0 generate slightly better loop code.
17320 * callint.c (Fcall_interactively): <, not <=, for optimization.
17321 (Fcall_interactively): Count the number of arguments produced,
17322 not the number of arguments given. This is simpler and lets GCC
17323 4.6.0 generate slightly better code.
17325 * ftfont.c: Distingish more carefully between FcChar8 and char.
17326 The previous code passed unsigned char * to a functions like
17327 strlen and xstrcasecmp that expect char *, which does not
17328 conform to the C standard.
17329 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
17330 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
17331 char * when the C standard requires it.
17333 * keyboard.c (read_char): Remove unused var.
17335 * eval.c: Port to Windows vsnprintf (Bug#8435).
17336 Include <limits.h>.
17337 (SIZE_MAX): Define if the headers do not.
17338 (verror): Do not give up if vsnprintf returns a negative count.
17339 Instead, grow the buffer. This ports to Windows vsnprintf, which
17340 does not conform to C99. Problem reported by Eli Zaretskii.
17341 Also, simplify the allocation scheme, by avoiding the need for
17342 calling realloc, and removing the ALLOCATED variable.
17344 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
17346 Remove invocations of doprnt, as Emacs now uses vsnprintf.
17347 But keep the doprint source code for now, as we might revamp it
17348 and use it again (Bug#8435).
17349 * lisp.h (doprnt): Remove.
17350 * Makefile.in (base_obj): Remove doprnt.o.
17351 * deps.mk (doprnt.o): Remove.
17353 error: Print 32- and 64-bit integers portably (Bug#8435).
17354 Without this change, on typical 64-bit hosts error ("...%d...", N)
17355 was used to print both 32- and 64-bit integers N, which relied on
17356 undefined behavior.

17365 * charset.c (check_iso_charset_parameter): Convert internal
17366 character to string before calling 'error', since %c now has the
17368 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
17369 overflow when computing char to be passed to 'error'. Do not
17370 pass Lisp_Object to 'error'; pass the integer instead.
17371 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
17372 formatted with plain %d.
17374 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.

17388 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
17389 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
17390 return ssize_t not "int", and use size_t as the buffer length.
17391 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
17392 * gnutls.h: Update declarations.
17393 * process.c (read_process_output): Use ssize_t, to match.

17402 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
17403 Use unsigned char, to match FcChar8 type definition.
17405 * xterm.c (handle_one_xevent):
17406 * xmenu.c (create_and_show_popup_menu):
17407 * xselect.c (x_decline_selection_request)

17509 This avoids several warnings with gcc -Wstrict-overflow.
17510 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
17511 directly, rather than having caller test rule sign. This avoids
17512 some unnecessary tests.
17513 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
17514 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
17515 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
17517 * xfont.c (xfont_text_extents): Remove var that was set but not used.
17518 (xfont_open): Avoid unnecessary tests.
17520 * composite.c (composition_gstring_put_cache): Use unsigned integer.

17526 breaking out part of COMPOSITION_DECODE_RULE.
17527 (COMPOSITION_DECODE_RULE): Use it.

17529 by using the new macro.
17531 * textprop.c (set_text_properties_1): Change while to do-while,
17532 since the condition is always true at first.
17534 * intervals.c (graft_intervals_into_buffer): Mark var as used.
17535 (interval_deletion_adjustment): Return unsigned value.
17538 * process.c (list_processes_1, create_pty, read_process_output):

17563 (sxhash): Redo loop for clarity and to avoid wraparound warning.
17565 * eval.c (funcall_lambda): Rename local to avoid shadowing.
17567 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
17568 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
17569 can always succeed if overflow has undefined behavior.
17571 * search.c (boyer_moore, wordify): Remove vars set but not used.
17572 (wordify): Omit three unnecessary tests.
17574 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.

17577 * casefiddle.c (casify_region): Remove var that is set but not used.
17579 * dired.c (file_name_completion): Remove var that is set but not used.
17581 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
17583 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
17584 (Finsert_file_contents): Remove unnecessary code checking fd.
17586 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
17587 Check for integer overflow on size calculations.
17589 * buffer.c (Fprevious_overlay_change): Remove var that is set
17592 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
17593 Remove vars that are set but not used.
17594 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.

17599 * image.c (lookup_image): Remove var that is set but not used.
17600 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
17602 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
17603 that are set but not used.
17605 * xfns.c (make_invisible_cursor): Don't return garbage
17606 if XCreateBitmapFromData fails (Bug#8410).
17608 * xselect.c (x_get_local_selection, x_handle_property_notify):
17609 Remove vars that are set but not used.
17611 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
17612 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
17614 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
17615 Remove var that is set but not used.
17616 (scroll_bar_windows_size): Now size_t, not int.
17617 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
17618 Check for overflow.

17629 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
17630 (decode_coding_charset): Remove vars that are set but not used.
17632 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
17633 that is set but not used.
17635 * print.c (print_object): Remove var that is set but not used.
17637 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
17638 The gnulib version avoids calling malloc in the usual case,
17639 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
17640 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
17641 * filelock.c (current_lock_owner): Likewise.
17642 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
17643 * sysdep.c: Include allocator.h, careadlinkat.h.
17644 (emacs_no_realloc_allocator): New static constant.
17645 (emacs_readlink): New function.
17646 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
17647 ../lib/careadlinkat.h.
17649 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
17651 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
17652 first non-nil return value).

17667 and thereabouts. All callers changed.
17668 (get_per_char_metric): Remove parameter `f', unused since
17669 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

17673 do not dereference NULL upon failed strdup
17674 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.

17703 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
17705 * keyboard.c (eval_dyn): New fun.
17706 (menu_item_eval_property): Use it.

17710 * fns.c (concat, mapcar1): Accept byte-code-functions.
17712 * eval.c (Fsetq): Handle lexical vars.
17713 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
17714 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
17715 (FletX, Flet): Obey lexical binding.
17716 (Fcommandp): Handle closures.
17717 (Feval): New `lexical' arg.
17718 (eval_sub): New function extracted from Feval. Use it almost
17719 everywhere where Feval was used. Look up vars in lexical env.
17721 (Ffunctionp): Move from subr.el.
17722 (Ffuncall): Handle closures.
17723 (apply_lambda): Remove `eval_flags'.
17724 (funcall_lambda): Handle closures and new byte-code-functions.
17725 (Fspecial_variable_p): New function.
17726 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
17727 but without exporting it to Lisp.
17729 * doc.c (Fdocumentation, store_function_docstring):
17730 * data.c (Finteractive_form): Handle closures.
17732 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
17735 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
17737 (exec_byte_code): New function extracted from Fbyte_code to handle new
17738 calling convention for byte-code-functions. Add new byte-codes.
17740 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
17742 * alloc.c (Fmake_symbol): Init new `declared_special' field.

17752 Limit scrolling to 100 screen lines.
17753 (redisplay_window): Even when falling back on "recentering",
17754 position point in the window according to scroll-conservatively,
17755 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
17757 (try_scrolling): When point is above the window, allow searching
17758 as far as scroll_max, or one screenful, to compute vertical
17759 distance from PT to the scroll margin position. This prevents
17760 try_scrolling from unnecessarily failing when
17761 scroll-conservatively is set to a value slightly larger than the
17762 window height. Clean up the case of PT below the margin at bottom
17763 of window: scroll_max can no longer be INT_MAX. When aggressive
17764 scrolling is in use, don't let point enter the opposite scroll
17765 margin as result of the scroll.
17766 (syms_of_xdisp) <scroll-conservatively>: Document the
17767 threshold of 100 lines for never-recentering scrolling.

17775 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
17776 (redisplay_internal): Remove parameter `preserve_echo_area',
17777 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
17779 * indent.c (Fvertical_motion):
17780 * window.c (window_scroll_pixel_based, Frecenter):
17781 Don't pass `need_y_p' to `move_it_by_lines'.
17783 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
17785 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
17786 steal a few bits to be more compact.

17809 * window.c (shrink_windows): Omit unused local var.
17810 * menu.c (digest_single_submenu): Omit unused local var.
17811 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
17812 Omit unused local var.
17814 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
17815 Don't assume string length fits in int.
17816 (keyremap_step, read_key_sequence): Use size_t for sizes.
17817 (read_key_sequence): Don't check last_real_key_start redundantly.
17819 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
17820 instead of alloca (Bug#8344).
17822 * eval.c (Fbacktrace): Don't assume nargs fits in int.
17823 (Fbacktrace_frame): Don't assume nframes fits in int.
17825 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
17827 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
17830 * term.c (produce_glyphless_glyph): Remove unnecessary test.
17832 * cm.c (calccost): Turn while-do into do-while, for clarity.
17834 * keyboard.c (syms_of_keyboard): Use the same style as later
17835 in this function when indexing through an array. This also
17836 works around GCC bug 48267.
17838 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
17840 * xselect.c (x_check_property_data): Return correct size (Bug#8335).

17843 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
17845 * keyboard.c, keyboard.h (num_input_events): Now size_t.
17846 This avoids undefined behavior on integer overflow, and is a bit
17847 more convenient anyway since it is compared to a size_t variable.
17849 Variadic C functions now count arguments with size_t, not int.
17850 This avoids an unnecessary limitation on 64-bit machines, which
17851 caused (substring ...) to crash on large vectors (Bug#8344).
17852 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
17853 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
17854 All variadic functions and their callers changed accordingly.

17859 (internal_condition_case_n, run_hook_with_args, apply_lambda)
17860 (funcall_lambda, mark_backtrace): Likewise.
17861 * fns.c (concat): Likewise.
17862 * frame.c (x_set_frame_parameters): Likewise.
17863 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
17864 0 if not found, not -1. All callers changed.
17866 * alloc.c (garbage_collect): Don't assume stack size fits in int.
17867 (stack_copy_size): Now size_t, not int.
17868 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.

17889 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
17890 don't set the hook to nil, but remove the offending function instead.
17891 (Qcommand_hook_internal): Remove, unused.
17892 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
17893 Vcommand_hook_internal.
17895 * eval.c (enum run_hooks_condition): Remove.
17896 (funcall_nil, funcall_not): New functions.
17897 (run_hook_with_args): Call each function through a `funcall' argument.

17907 * print.c (strout): Remove parameter `multibyte', unused since
17908 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
17910 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
17911 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
17912 All callers changed.
17914 * w32.c (_wsa_errlist): Use braces for struct initializers.

17924 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
17925 All callers changed.
17927 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
17929 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.

17958 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
17960 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
17962 * w32.c (read_unc_volume): Use parameter `henum', instead of
17963 global variable `wget_enum_handle'.
17965 * keymap.c (describe_vector): Remove parameters `indices' and

18061 2011-03-23 Julien Danjou <julien@danjou.info>
18063 * term.c (Fsuspend_tty, Fresume_tty):
18064 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
18065 * window.c (temp_output_buffer_show):

18072 * callint.c (Fcall_interactively):
18073 * buffer.c (Fkill_all_local_variables):
18074 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
18076 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
18077 unconditionally since it does the check itself.
18079 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
18081 Fix more problems found by GCC 4.5.2's static checks.
18083 * coding.c (encode_coding_raw_text): Avoid unnecessary test
18084 the first time through the loop, since we know p0 < p1 then.
18085 This also avoids a gcc -Wstrict-overflow warning.
18087 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
18088 leading to a memory leak, possible in functions like
18089 load_charset_map_from_file that can allocate an unbounded number
18090 of objects (Bug#8318).
18092 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
18093 that could (at least in theory) be that large.
18095 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
18096 This is less likely to overflow, and avoids undefined behavior if
18097 overflow does occur. All callers changed. Use strtoul to scan
18098 for the unsigned long integer.
18099 (pint2hrstr): Simplify and tune code slightly.
18100 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

18115 * process.c (Fmake_network_process): Use socklen_t, not int,
18116 where POSIX says socklen_t is required in portable programs.
18117 This fixes a porting bug on hosts like 64-bit HP-UX, where
18118 socklen_t is wider than int (Bug#8277).
18119 (Fmake_network_process, server_accept_connection):
18120 (wait_reading_process_output, read_process_output):
18123 * process.c: Rename or move locals to avoid shadowing.

18130 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
18131 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
18133 Make tparam.h and terminfo.c consistent.
18134 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
18135 Include tparam.h instead, since it declares them.
18136 * cm.h (PC): Remove extern decl; tparam.h now does this.
18137 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
18138 * terminfo.c: Include tparam.h, to check interfaces.
18139 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
18140 (tparam): Adjust signature to match interface in tparam.h;
18141 this removes some undefined behavior. Check that outstring and len
18142 are zero, which they always are with Emacs.
18143 * tparam.h (PC, BC, UP): New extern decls.
18145 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
18146 (xftfont_open): Rename locals to avoid shadowing.
18148 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
18149 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.

18152 (get_adstyle_property, ftfont_pattern_entity):
18153 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
18154 Rename locals to avoid shadowing.
18156 * xfont.c (xfont_list_family): Mark var as initialized.
18158 * xml.c (make_dom): Now static.
18160 * composite.c (composition_compute_stop_pos): Rename local to
18162 (composition_reseat_it): Remove unused locals.
18163 (find_automatic_composition, composition_adjust_point): Likewise.
18164 (composition_update_it): Mark var as initialized.
18165 (find_automatic_composition): Mark vars as initialized,
18166 with a FIXME (Bug#8290).
18168 character.h: Rename locals to avoid shadowing.
18169 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
18170 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
18171 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
18172 (BUF_DEC_POS): Be more systematic about renaming local temporaries
18173 to avoid shadowing.
18175 * textprop.c (property_change_between_p): Remove; unused.
18177 * intervals.c (interval_start_pos): Now static.
18179 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".
18181 * atimer.c (start_atimer, append_atimer_lists, set_alarm):
18182 Rename locals to avoid shadowing.
18184 * sound.c (wav_play, au_play, Fplay_sound_internal):
18185 Fix pointer signedness.
18186 (alsa_choose_format): Remove unused local var.
18187 (wav_play): Initialize a variable to 0, to prevent undefined
18188 behavior (Bug#8278).
18190 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
18192 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
18194 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
18195 clobbering (Bug#8298).
18196 * sysdep.c (sys_subshell): Likewise.
18197 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
18199 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
18200 This should get cleaned up, so that child_setup has the
18201 same signature on all platforms.
18203 * callproc.c (call_process_cleanup): Now static.
18204 (relocate_fd): Rename locals to avoid shadowing.
18206 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
18208 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
18209 not to be necessary, and produces flickering.
18211 2011-03-20 Glenn Morris <rgm@gnu.org>
18213 * config.in: Remove file.
18215 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
18217 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
18218 are now in src/globals.h.
18219 (syms_of_minibuf): Remove spurious & from previous change.

18245 (sigchld_handler): Now static.
18247 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
18248 That way, the code declares only the vars that it needs.

18263 to avoid gcc -Wbad-function-cast warning.
18264 Use a different way to cause a compilation error if anyone uses

18334 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
18335 some of which prompt warnings from gcc -Wbad-function-cast.
18336 (Fformat_time_string, Fencode_time, Finsert_char):

18365 (Fmemory_limit): Cast sbrk's returned value to char *.
18367 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this

18373 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
18374 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
18375 to use the following functions instead of these macros.
18376 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
18377 EMACS_INT, since callers assume the returned value fits in int.
18378 (upcase1): Likewise, for UPCASE_TABLE.
18379 (uppercasep, lowercasep, upcase): New static inline functions.
18380 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

18390 (regex_compile, re_match_2_internal): Mark locals as initialized.
18391 (RETALLOC_IF): Define only if needed.
18392 (WORDCHAR_P): Likewise. This one is never needed, but is used
18393 only in a comment talking about a compiler bug, so put inside
18394 the #if 0 of that comment.
18395 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
18396 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

18422 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
18423 New macros, so that the caller can use some names other than
18424 gcpro1, gcpro2, etc.
18425 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
18427 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
18428 argument, for consistency with GCPRO2_VAR, etc: it is now the
18429 prefix of the variable, not the variable itself. All uses
18431 * dired.c (directory_files_internal, file_name_completion):
18432 Rename locals to avoid shadowing.
18434 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
18435 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
18436 dired.c's scmp function, had undefined behavior.
18437 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
18438 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
18439 * buffer.h: ... to here, because these macros use current_buffer,
18440 and the new implementation with inline functions needs to have
18441 current_buffer in scope now, rather than later when the macros
18443 (downcase, upcase1): New static inline functions.
18444 (DOWNCASE, UPCASE1): Reimplement using these functions.
18445 This avoids undefined behavior in expressions like
18446 DOWNCASE (x) == DOWNCASE (y), which previously suffered
18447 from race conditions in accessing the global variables
18448 case_temp1 and case_temp2.
18449 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
18450 * lisp.h (case_temp1, case_temp2): Remove their decls.
18451 * character.h (ASCII_CHAR_P): Move from here ...
18452 * lisp.h: ... to here, so that the inline functions mentioned
18453 above can use them.
18455 * dired.c (directory_files_internal_unwind): Now static.
18457 * fileio.c (file_name_as_directory, directory_file_name):

18460 (file_name_as_directory): Use const pointers when appropriate.
18461 (Fexpand_file_name): Likewise. In particular, newdir might
18462 point at constant storage, so make it a const pointer.
18463 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
18464 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
18466 (Fset_file_times, Finsert_file_contents, auto_save_error):

18471 to avoid shadowing.
18473 * marker.c (bytepos_to_charpos): Remove; unused.
18475 * lisp.h (verify_bytepos, count_markers): New decls,
18476 so that gcc does not warn that these functions aren't declared.
18478 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
18479 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
18480 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
18481 (copy_text): Remove unused local var.
18483 * filelock.c (within_one_second): Now static.
18484 (lock_file_1): Rename local to avoid shadowing.
18486 * buffer.c (fix_overlays_before): Mark locals as initialized.
18487 (fix_start_end_in_overlays): Likewise. This function should be
18488 simplified by using pointers-to-pointers, but that's a different
18490 (switch_to_buffer_1): Now static.
18491 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
18492 (report_overlay_modification): Rename locals to avoid shadowing.

18495 Fix pointer signedness issue.
18496 (sys_subshell): Mark local as volatile if checking for lint,
18497 to suppress a gcc -Wclobbered warning that does not seem to be right.
18498 (MAXPATHLEN): Define only if needed.
18500 * process.c (serial_open, serial_configure): Move decls from here ...
18501 * systty.h: ... to here, so that they can be checked.
18503 * fns.c (get_random, seed_random): Move extern decls from here ...
18504 * lisp.h: ... to here, so that they can be checked.
18506 * sysdep.c (reset_io): Now static.
18507 (wait_for_termination_signal): Remove; unused.
18509 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):

18515 (describe_map_tree):
18516 Rename locals to avoid shadowing.

18665 For example, without this patch (encode-time 0 0 0 1 1
18666 1152921504606846976) returns the obviously-bogus value (-948597
18667 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
18668 reports time overflow. See
18669 <http://lists.gnu.org/archive/html/emacs-devel/2011-03/msg00470.html>.
18670 * deps.mk (editfns.o): Depend on ../lib/intprops.h.
