3 * window.c (Vwindow_combination_limit): New default value.
4 (Qwindow_size): New symbol replacing Qtemp_buffer_resize.
6 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
8 * syssignal.h (PROFILER_CPU_SUPPORT): Don't define if PROFILING.
9 Suggested by Eli Zaretskii in
10 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00811.html>.
12 2012-09-30 Eli Zaretskii <eliz@gnu.org>
14 * profiler.c (Fprofiler_cpu_stop): Use timer_settime only if
15 HAVE_TIMER_SETTIME is defined.
17 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
19 Profiler improvements: more-accurate timers, overflow checks.
20 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
21 signal.h, setjmp.h. Include systime.h instead.
22 (saturated_add): New function.
23 (record_backtrace, current_sample_interval): Use EMACS_INT, not size_t.
24 (record_backtrace, handle_profiler_signal): Saturate on fixnum overflow.
25 (profiler_timer, profiler_timer_ok) [HAVE_TIMER_SETTIME]:
27 (enum profiler_cpu_running): New enum.
28 (profiler_cpu_running): Now of that enum type, not bool.
29 All uses changed to store the new value.
30 (handle_profiler_signal): Rename from sigprof_handler_1,
31 for consistency with other handlers. Do not check whether
32 cpu_log is a hash-table if garbage collecting, since it
33 doesn't matter in that case.
34 (deliver_profiler_signal): Rename from sigprof_handler,
35 for consistency with other handlers.
36 (setup_cpu_timer): New function, with much of what used to be in
37 Fprofiler_cpu_start. Check for out-of-range argument.
38 Prefer timer_settime if available, and prefer
39 thread cputime clocks, then process cputime clocks, then
40 monotonic clocks, to the old realtime clock. Use make_timeval
41 to round more-correctly when falling back to setitimer.
42 (Fprofiler_cpu_start): Use it.
43 (Fprofiler_cpu_stop): Prefer timer_settime if available.
44 Don't assume that passing NULL as the 2nd argument of setitimer
45 is the same as passing a pointer to all-zero storage.
46 Ignore SIGPROF afterwards.
47 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
48 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
49 non-fatal signal handlers. Ignore SIGPROF on startup.
50 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
51 in profiler.c, since sysdep.c now uses it.
53 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.

103 * makefile.w32-in ($(BLD)/profiler.$(O)): Update dependencies.
105 2012-09-26 Paul Eggert <eggert@cs.ucla.edu>
107 * character.h (MAYBE_UNIFY_CHAR): Remove.
108 * charset.c, charset.h (maybe_unify_char): Now static.
109 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
110 Since this stuff is now private to charset.c, there's no need for
111 a public macro and no need to inline by hand.

144 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>
146 Prefer POSIX timers if available.
147 They avoid a race if the timer is too close to the current time.
148 * atimer.c (alarm_timer, alarm_timer_ok) [SIGEV_SIGNAL]: New static vars.
149 (set_alarm) [SIGEV_SIGNAL]: Use POSIX timers if available.
150 (init_atimer) [SIGEV_SIGNAL]: Initialize them.
152 2012-09-25 Eli Zaretskii <eliz@gnu.org>

175 * w32.h (Vlibrary_cache): Do not declare.
177 2012-09-25 Eli Zaretskii <eliz@gnu.org>
179 * w32proc.c (sys_signal): Handle all signals defined by the
180 MS-Windows runtime, not just SIGCHLD. Actually install the signal
181 handlers for signals supported by Windows. Don't override
182 term_ntproc as the handler for SIGABRT.
183 (sigaction): Rewrite to call sys_signal instead of duplicating its
185 (sys_kill): Improve commentary.
187 * w32.c (term_ntproc): Accept (and ignore) one argument, for
188 consistency with a signature of a signal handler. All callers
190 (init_ntproc): Accept an argument DUMPING. If dumping, don't
191 install term_ntproc as a signal handler for SIGABRT, as that
192 should be done by the dumped Emacs.
194 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
196 * w32select.c (term_w32select): Protect against repeated
197 invocation by setting clipboard_owner to NULL after calling
200 * emacs.c (shut_down_emacs, main): Adapt the calls to init_ntproc
201 and term_ntproc to their modified signatures.
203 * character.c (char_string, string_char): Remove calls to
204 MAYBE_UNIFY_CHAR. See the discussion starting at
205 http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00433.html

215 when encountering an unknown bytecode.
217 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
219 image.c, indent.c: Use bool for booleans.
220 * dispextern.h (struct image_type): Members valid_p, load, init
221 now return bool, not int. All uses changed.
222 * image.c: Omit unnecessary static decls.
223 (x_create_bitmap_mask, x_build_heuristic_mask):
224 Return void, not int, since callers don't care about the return value.

261 Move pid_t related decls out of lisp.h.
262 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
263 (interruptible_wait_for_termination):
264 Move these decls from lisp.h to syswait.h, since they use pid_t.
265 Needed on FreeBSD; see Herbert J. Skuhra in
266 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
267 * callproc.c: Include syswait.h.

313 2012-09-23 Eli Zaretskii <eliz@gnu.org>
315 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
316 fatal_error_backtrace.
318 * w32proc.c (sys_kill): Undo last change: don't do anything when
319 invoked to deliver SIGABRT to our own process. This is now
320 handled by emacs_raise.
322 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
324 * w32term.c (w32_read_socket): Remove leftover reference to
325 interrupt_input_pending.
327 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
329 Do not use SA_NODEFER.
330 Problem reported by Dani Moncayo in
331 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
333 * sysdep.c (emacs_abort): Do not reset signal handler.
334 * emacs.c (terminate_due_to_signal): Reset signal handler here.
335 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
336 wanted even on POSIXish hosts, and it doesn't work on Windows.
338 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
340 * xterm.c (x_term_init): Call fixup_locale before and after calling
341 gtk_init (Bug#12392).
343 2012-09-23 Chong Yidong <cyd@gnu.org>
345 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
346 Vdynamic_library_alist.
348 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
349 (Fgnutls_available_p): Caller changed.
351 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
352 (Flibxml_parse_xml_region): Likewise.
354 * dispextern.h (struct image_type): Remove arg from init function.
356 * image.c (Finit_image_library, lookup_image_type)

358 (init_xpm_functions, init_png_functions, init_jpeg_functions)
359 (init_tiff_functions, init_gif_functions, init_svg_functions):
360 Arglist and w32_delayed_load calling convention changed.
361 (gs_type): Remove init_gs_functions; there is no such function.
362 (valid_image_p, make_image): Fix caller to lookup_image_type.
364 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
366 Simplify and avoid signal-handling races (Bug#12471).
368 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
369 Avoid recursive loop if there's a fatal error in the function itself.
370 * atimer.c (pending_atimers):
371 * blockinput.h: Don't include "atimer.h"; no longer needed.
372 (interrupt_input_pending): Remove. All uses removed.
373 pending_signals now counts both atimers and ordinary interrupts.
374 This is less racy than having three separate pending-signal flags.
375 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
377 Rename from their upper-case counterparts BLOCK_INPUT,
378 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
379 INPUT_BLOCKED_P, and turn into functions. All uses changed.
380 This makes it easier to access volatile variables more accurately.
381 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
382 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
383 that's more reliable if the code is buggy and sets
384 interrupt_input_blocked to a negative value. All uses changed.
385 * atimer.c (deliver_alarm_signal):
386 Remove. No need to deliver this to the parent; any thread can
387 handle this signal now. All uses replaced by underlying handler.
388 * atimer.c (turn_on_atimers):
389 * dispnew.c (handle_window_change_signal):
390 * emacs.c (handle_danger_signal):
391 * keyboard.c (kbd_buffer_get_event):
392 Don't reestablish signal handler; not needed with sigaction.
393 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
395 Rework to avoid unnecessary accesses to volatile variables.
396 (UNBLOCK_INPUT_TO): Now a function.
397 (totally_unblock_input, unblock_input): New decls.
398 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
399 (init_data): Remove. Necessary stuff now done in init_signal.
400 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
401 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
402 (fatal_error_code): Remove; no longer needed.
403 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
404 it doesn't always backtrace. All uses changed. No need to reset
405 signal to default, since sigaction and/or die does that for us now.
406 Use emacs_raise (FOO), not kill (getpid (), FOO).
407 (main): Check more-accurately whether we're dumping.
408 Move fatal-error setup to sysdep.c
409 * floatfns.c: Do not include "syssignal.h"; no longer needed.
410 * gtkutil.c (xg_get_file_name, xg_get_font):
411 Remove no-longer-needed signal-mask manipulation.
412 * keyboard.c, process.c (POLL_FOR_INPUT):
413 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
414 * keyboard.c (read_avail_input): Remove.
415 All uses replaced by gobble_input.
416 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
417 (kbd_buffer_store_event_hold, gobble_input):
418 (record_asynch_buffer_change) [USABLE_SIGIO]:
419 (store_user_signal_events):
420 No need to mess with signal mask.
421 (gobble_input): If blocking input and there are terminals, simply
422 set pending_signals to 1 and return. All hooks changed to not
423 worry about whether input is blocked.
424 (process_pending_signals): Clear pending_signals before processing
425 them, in case a signal comes in while we're processing.
426 By convention callers now test pending_signals before calling us.
427 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
428 New functions, to support changes to blockinput.h.
429 (handle_input_available_signal): Now extern.
430 (reinvoke_input_signal): Remove. All uses replaced by
432 (quit_count): Now volatile, since a signal handler uses it.
433 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
434 All callers changed. Block SIGINT only if not already blocked.
435 Clear sigmask reliably, even if Fsignal returns, which it can.
436 Omit unnecessary accesses to volatile var.
437 (quit_throw_to_read_char): No need to restore sigmask.
438 * keyboard.c (gobble_input, handle_user_signal):
439 * process.c (wait_reading_process_output):
440 Call signal-handling code rather than killing ourselves.
441 * lisp.h: Include <float.h>, for...
442 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
443 (pending_signals): Now volatile.
444 (syms_of_data): Now const if IEEE floating point.
445 (handle_input_available_signal) [USABLE_SIGIO]:
446 (terminate_due_to_signal, record_child_status_change): New decls.
447 * process.c (create_process): Avoid disaster if memory is exhausted
448 while we're processing a vfork, by tightening the critical section
450 (send_process_frame, process_sent_to, handle_pipe_signal)
451 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
453 (send_process): No need for setjmp/longjmp any more, since the
454 SIGPIPE stuff is now gone. Instead, report an error if errno
456 (record_child_status_change): Now extern. PID and W are now args.
457 Return void, not bool. All callers changed.
458 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
459 Remove. All uses removed. This bug should be fixed now in a
461 (wait_for_termination_1): Use waitpid rather than sigsuspend,
462 and record the child status change directly. This avoids the
463 need to futz with the signal mask.
464 (process_fatal_action): Move here from emacs.c.
465 (emacs_sigaction_flags): New function, containing
466 much of what used to be in emacs_sigaction_init.
467 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
468 caught by emacs, to make races less likely.
469 (deliver_process_signal): Rename from handle_on_main_thread.
471 (BACKTRACE_LIMIT_MAX): Now at top level.
472 (thread_backtrace_buffer, threadback_backtrace_pointers):
474 (deliver_thread_signal, deliver_fatal_thread_signal):
475 New functions, for more-accurate delivery of thread-specific signals.
476 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
477 (deliver_arith_signal): Handle in this thread, not
478 in the main thread, since it's triggered by this thread.
479 (maybe_fatal_sig): New function.
480 (init_signals): New arg DUMPING so that we can be more accurate
481 about whether we're dumping. Caller changed.
482 Treat thread-specific signals differently from process-general signals.
483 Block all signals while handling fatal error; that's safer.
484 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
486 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
487 Ignore SIGPIPE unless batch.
488 (emacs_backtrace): Output backtrace for the appropriate thread,
489 which is not necessarily the main thread.
490 * syssignal.h: Include <stdbool.h>.
491 (emacs_raise): New macro.
492 * xterm.c (x_connection_signal): Remove; no longer needed
493 now that we use sigaction.
494 (x_connection_closed): No need to mess with sigmask now.
495 (x_initialize): No need to reset SIGPIPE handler here, since
496 init_signals does this for us now.
498 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
500 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
501 background rect may be larger (Bug#12245).
503 2012-09-23 Chong Yidong <cyd@gnu.org>
505 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
507 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
509 * .gdbinit: Just stop at fatal_error_backtrace.
510 See Stefan Monnier's request in
511 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
512 Remove no-longer-used query of system type.
514 2012-09-22 Chong Yidong <cyd@gnu.org>
516 * search.c (Freplace_match): Doc fix (Bug#12325).
518 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
520 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
521 (Fline_end_position): Doc fix.
523 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
525 2012-09-22 Chong Yidong <cyd@gnu.org>
527 * dispextern.h (struct image_type): Add new slot, storing a type
528 initialization function.
530 * image.c (define_image_type): Call the image initializer function
531 if it is defined. Arguments and return value changed.
532 (valid_image_p, make_image): Callers changed.
533 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
534 (gif_type, imagemagick_type, svg_type, gs_type):
535 Add initialization functions.
536 (Finit_image_library): Call lookup_image_type.
537 (CHECK_LIB_AVAILABLE): Macro deleted.
538 (lookup_image_type): Call define_image_type here, rather than via
539 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
540 (syms_of_image): Move define_image_type calls for xbm_type and
541 pbm_type to lookup_image_type.
543 2012-09-22 Eli Zaretskii <eliz@gnu.org>
545 * keyboard.c (timer_check_2): Move calculation of 'timers' and
546 'idle_timers' from here ...
547 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
548 lists, to avoid infloops when the timer does something stupid,
549 like reinvoke itself with the same or smaller time-out.
552 2012-09-22 Martin Rudalics <rudalics@gmx.at>
554 * window.c (Fsplit_window_internal): Handle only Qt value of
555 Vwindow_combination_limit separately.
556 (Qtemp_buffer_resize): New symbol.
557 (Vwindow_combination_limit): New default value.
560 2012-09-22 Eli Zaretskii <eliz@gnu.org>
562 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
563 the new overlay string. (Bug#10159)
565 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
567 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
568 or that fprintf is async-signal-safe. POSIX doesn't require
571 2012-09-22 Chong Yidong <cyd@gnu.org>
573 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
576 2012-09-22 Kenichi Handa <handa@gnu.org>
578 * composite.c (composition_reseat_it): Handle the case that a
579 grapheme cluster is not covered by a single font (Bug#12352).
581 2012-09-21 Chong Yidong <cyd@gnu.org>
583 * image.c (define_image_type): Avoid adding duplicate types to
584 image_types (Bug#12463). Suggested by Jörg Walter.
586 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
588 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
589 (print_load_command_name): Add case LC_DATA_IN_CODE.
590 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
592 2012-09-21 Glenn Morris <rgm@gnu.org>
594 * eval.c (Frun_hook_with_args_until_success)
595 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
597 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
599 * fileio.c (Ffile_selinux_context): Only call freecon when
600 lgetfilecon succeeded.
601 (Fset_file_selinux_context): Likewise. (Bug#12444)
603 2012-09-21 Eli Zaretskii <eliz@gnu.org>
605 * xdisp.c (try_window_reusing_current_matrix): Under bidi
606 reordering, locate the cursor by calling set_cursor_from_row; if
607 that fails, clear the desired glyph matrix before returning a
608 failure indication to the caller. Fixes leaving garbled display
609 when fast scrolling with a down-key. (Bug#12403)
610 (compute_stop_pos_backwards): Fix a typo that caused crashes while
611 scrolling through multibyte text.
613 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
615 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
616 calling mark_vectorlike since that's the one that marks the window.
617 (mark_discard_killed_buffers): Mark the final cdr.
618 * window.h (struct window): Move prev/next_buffers to the
620 * window.c (make_window): Initialize prev/next_buffers manually.
622 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
624 Omit unused arg EXPECTED from socket hooks.
625 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
626 * nsterm.m (ns_term_init):
627 * termhooks.h (struct terminal.read_socket_hook):
628 * w32inevt.c (w32_console_read_socket):
629 * w32term.c (w32_read_socket):
630 * xterm.c (XTread_socket):
631 Omit unused arg EXPECTED. All callers changed.
632 (store_user_signal_events): Return void, not int, since callers no
633 longer care about the return value. All uses changed.
635 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
637 * w32gui.h (XParseGeometry): Do not declare.
639 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
641 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
642 Ignore 'expected'. See Eli Zaretskii in
643 <http://bugs.gnu.org/12471#8> (last line).
645 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
646 (XParseGeometry): Now static. Substitute extremal values for
647 values that are out of range.
649 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
651 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
653 * nsfns.m (XParseGeometry): Remove.
654 (Fx_create_frame): Call x_set_offset to correctly interpret
657 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
658 (Fx_parse_geometry): If there is a space in string, call
659 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
661 2012-09-17 Eli Zaretskii <eliz@gnu.org>
663 * search.c (scan_buffer): Use character positions in calls to
664 region_cache_forward and region_cache_backward, not byte
665 positions. (Bug#12196)
667 * w32term.c (w32_read_socket): Set pending_signals to 1, like
668 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
670 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
671 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
672 emacs_blocked_malloc, now deleted.
674 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
676 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
677 The workaround was for improving performance on Solaris 2.4, but
678 is getting in the way now. Emacs will still work if someone is
679 still running Solaris 2.4 in a museum somewhere; Sun dropped
680 support for Solaris 2.4 in 2003.
681 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
682 * process.c (create_process) [HAVE_WORKING_VFORK]:
683 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
684 since Emacs no longer uses vfork on that platform.
686 2012-09-17 Glenn Morris <rgm@gnu.org>
688 * emacs.c: Use COPYRIGHT.
690 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
692 Remove configure's --without-sync-input option (Bug#12450).
693 When auditing signal-handling in preparation for cleaning it up,
694 I found that SYNC_INPUT has race conditions and would be a real
695 pain to fix. Since it's an undocumented and deprecated
696 configure-time option, now seems like a good time to remove it.
697 Also see <http://bugs.gnu.org/11080#16>.
698 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
699 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
700 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
702 (check_depth) [XMALLOC_OVERRUN_CHECK]:
703 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
704 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
705 (dont_register_blocks, bytes_used_when_reconsidered)
706 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
707 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
708 [!SYSTEM_MALLOC && !SYNC_INPUT]:
709 Remove. All uses removed.
710 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
711 implementation, one that depends on whether the new macro
712 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
714 * atimer.c (run_timers, handle_alarm_signal):
715 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
716 (handle_async_input, process_pending_signals)
717 (handle_input_available_signal, init_keyboard):
718 * nsterm.m (ns_read_socket):
719 * process.c (wait_reading_process_output):
720 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
721 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
723 * xterm.c (XTread_socket):
725 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
726 * eval.c (handling_signal): Remove. All uses removed.
727 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
728 All uses replaced with the SYNC_INPUT version.
729 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
731 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
734 * font.c (Ffont_shape_gstring): Remove unused local.
736 2012-09-16 Glenn Morris <rgm@gnu.org>
738 * Makefile.in (clean): No longer run nextstep's clean.
740 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
742 (ns-app): Move here from ns.mk, and simplify.
743 (clean): Simplify nextstep entry.
744 * ns.mk: Remove file.
746 2012-09-17 Kenichi Handa <handa@gnu.org>
748 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
749 not covert the last few charactes.
751 2012-09-16 Kenichi Handa <handa@gnu.org>
753 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
754 here, but just check the validity of glyphs in the glyph-string.
756 2012-09-16 Martin Rudalics <rudalics@gmx.at>
758 * window.c (Fwindow_parameter, Fset_window_parameter):
759 Accept any window as argument (Bug#12452).
761 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
763 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
764 to ns_term_init to avoid memory leak.
766 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
767 explicit retain/release.
768 (ns_term_init): Only allow one display. Initialize outerpool and
771 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
773 Port _setjmp fix to POSIXish hosts as well as Microsoft.
774 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
775 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
776 the Microsoft problem in a different way, by altering ../nt/config.nt.
778 2012-09-15 Eli Zaretskii <eliz@gnu.org>
793 * w16select.c: Remove inclusion of setjmp.h, as it is now included
794 by lisp.h. This completes removal of setjmp.h inclusion
795 erroneously announced in the previous commit. (Bug#12446)
797 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
800 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
801 not defined as a macro. The latter happens on MS-Windows.
804 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
806 Port better to POSIX hosts lacking _setjmp (Bug#12446).
807 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
808 Some instances of '#include <setjmp.h>' removed, if the
809 only reason for the instance was because "lisp.h" was included.
810 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
811 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
812 and _longjmp with the new symbols. Emacs already uses _setjmp if
813 available, so this change affects only POSIXish hosts that have
814 sigsetjmp but not _setjmp, such as some versions of Solaris and
815 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
816 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
817 (png_load_body) [HAVE_PNG]:
818 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
819 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
820 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
821 since PNG requires jmp_buf. This is the only exception to the
822 general rule that we now use sys_setjmp and sys_longjmp.
823 This exception is OK since this code does not change the signal
824 mask or longjmp out of a signal handler.
826 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
828 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
829 Include "syssignal.h", for 'main_thread'.
831 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
833 Avoid out-of-range marker position (Bug#12426).
834 * insdel.c (replace_range, replace_range_2):
835 Adjust markers before overlays, as suggested by comments.
836 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
837 Remove redundant check before calling offset_intervals.
839 2012-09-14 Martin Rudalics <rudalics@gmx.at>
841 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
842 current buffer (Bug#12387).
844 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
846 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
848 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
850 Use a more backwards-compatible timer format (Bug#12430).
851 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
852 vector element, not from the 4th, since PSECS is now at the end.
853 (Fcurrent_idle_time): Doc fix.
855 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
857 Function to mark objects and remove killed buffers at once.
858 * alloc.c (discard_killed_buffers): Rename to ...
859 (mark_discard_killed buffers) ... new name. Add marking
860 of remaining objects. Fix comment. Adjust users.
861 (mark_object): Do not touch frame buffer lists here.
862 * frame.c (delete_frame): Reset frame buffer lists here.
864 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
866 Better workaround for GNOME bug when --enable-gcc-warnings.
867 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
868 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
869 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
871 Simplify SIGIO usage (Bug#12408).
872 The code that dealt with SIGIO was crufty and confusing, e.g., it
873 played tricks like "#undef SIGIO" but these tricks were not used
874 consistently. Simplify mostly by not #undeffing standard symbols,
875 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
876 or not as we please) rather than "defined SIGIO" (standard symbol
877 that we probably shouldn't #undef).
878 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
879 Modules that need it can include it.
880 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
881 * dispextern.h (ignore_sigio): New decl.
882 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
883 unconditionally, since it's now a no-op if !USABLE_SIGIO.
884 * emacs.c (shut_down_emacs):
885 * keyboard.c (kbd_buffer_store_event_hold):
886 Use ignore_sigio rather than invoking 'signal' directly.
887 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
889 (FIONREAD, SIGIO): Do not #undef.
890 (tty_read_avail_input): Use #error rather than a syntax error.
891 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
892 for I_PIPE, used by SETUP_SLAVE_PTY.
893 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
894 * sysdep.c (croak): Remove; no longer needed. This bit of
895 temporary code, with Fred N. Fish's comment that it's temporary,
896 has been in Emacs since at least 1992!
897 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
898 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
899 * syssignal.h (croak): Remove decl.
900 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
901 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
902 now that we're termios-only.
903 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
904 * term.c (dissociate_if_controlling_tty): Use #error rather than
907 Work around GCC and GNOME bugs when --enable-gcc-warnings.
908 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
909 to work around GNOME bug 683906.
910 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
911 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
912 This works around GCC bug 54561.
914 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
916 More fixes for 'volatile' and setjmp/longjmp.
917 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
918 * image.c (struct png_load_context) [HAVE_PNG]: New type.
919 (png_load_body) [HAVE_PNG]:
920 (jpeg_load_body) [HAVE_JPEG]:
921 New function, with most of the old parent function's body.
922 (png_load) [HAVE_PNG]:
923 (jpeg_load) [HAVE_JPEG]:
924 Invoke the new function, to avoid longjmp munging our locals.
925 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
926 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
927 longjmp is passed 2, as the C standard doesn't guarantee this.
928 Instead, store the failure code into mgr->failure_code.
930 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
932 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
933 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
934 (syms_of_keyboard): Remove support for unread-command-char.
936 2012-09-12 Eli Zaretskii <eliz@gnu.org>
938 * w32proc.c (sys_kill): If PID is our process ID and the signal is
939 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
940 violation. (Bug#12426)
942 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
944 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
946 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
948 * eval.c: Add `inhibit-debugger'.
949 (Qinhibit_debugger): New symbol.
950 (call_debugger): Bind it instead of Qdebug_on_error.
951 (maybe_call_debugger): Test Vinhibit_debugger.
952 (syms_of_eval): Define inhibit-debugger.
953 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
954 (syms_of_xdisp): Remove inhibit-debug-on-message.
956 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
958 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
959 If a nonvolatile local variable is written before a _longjmp to
960 the frame containing the variable, and is read after the _longjmp,
961 the value read is indeterminate. Some local variables of type
962 'struct handler' and 'struct catchtag' are used in this way, so
963 mark each of their slots as volatile if the slot can be set before
964 _longjmp and read afterwards.
965 * lisp.h (struct handler): var and chosen_clause are now volatile.
966 (struct catchtag): val, next, and pdlcount are now volatile.
968 * bidi.c (bidi_push_it, bidi_pop_it):
969 * fns.c (copy_hash_table):
970 * image.c (define_image_type):
971 * keyboard.c (kbd_buffer_store_event_hold):
972 * process.c (Fprocess_send_eof):
973 * xfaces.c (x_create_gc) [HAVE_NS]:
974 * xgselect.c (xg_select):
975 Prefer assignment to memcpy when either will do.
977 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
978 Use pointer-to-a-pointer to simplify and avoid a NILP check each
979 time an item is removed. No need to mark this function 'inline';
980 the compiler knows better than we do.
982 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
984 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
985 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
986 to change_frame_size (Bug#12388).
987 (windowDidResize:): Pass YES to updateFrameSize.
989 * nsterm.h: Add delay parameter to updateFrameSize.
991 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
993 Discard killed buffers from deleted window and frame objects.
994 This reduces an amount of references to killed buffers and
995 helps GC to reclaim them faster.
996 * alloc.c (discard_killed_buffers): New function.
997 (mark_object): Use it for deleted windows and frames.
998 (mark_object): If symbol's value is set up for a killed buffer
999 or deleted frame, restore it's global binding.
1000 * data.c (swap_in_global_binding): Add GC notice.
1001 (swap_in_symval_forwarding): Use convenient set_blv_where.
1002 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
1003 * window.h: ... to here.
1005 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
1007 Convenient macro to check whether the buffer is live.
1008 * buffer.h (BUFFER_LIVE_P): New macro.
1009 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
1010 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
1012 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1014 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
1015 composition cases (Bug#12364).
1017 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
1018 overhang of succeeding glyphs overlapping box cursor.
1020 * w32term.c (x_draw_glyph_string): Likewise.
1022 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
1024 Simplify, document, and port floating-point (Bug#12381).
1025 The porting part of this patch fixes bugs on non-IEEE platforms
1026 with frexp, ldexp, logb.
1027 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
1029 * floatfns.c: Simplify discussion of functions that Emacs doesn't
1030 support, by removing commented-out code and briefly listing the
1031 C89 functions excluded. The commented-out stuff was confusing
1032 maintenance, e.g., we thought we needed cbrt but it was commented out.
1033 (logb): Remove decl; no longer needed.
1034 (isfinite): New macro, if not already supplied.
1035 (isnan): Don't replace any existing macro.
1036 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
1037 are present on all C89 platforms.
1038 (Ffrexp): Do not special-case zero, as frexp does the right thing
1040 (Flogb): Do not use logb, as it doesn't have the desired meaning
1041 on hosts that use non-base-2 floating point. Instead, stick with
1042 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
1043 frexp, to avoid getting an unspecified result.
1045 * xdisp.c (Qinhibit_debug_on_message): Now static.
1047 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
1049 * nsterm.m (ns_update_begin): Set clip path to whole view by using
1050 NSBezierPath (Bug#12131).
1052 2012-09-10 Chong Yidong <cyd@gnu.org>
1054 * fns.c (Fdelq, Fdelete): Doc fix.
1056 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
1058 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
1059 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
1061 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
1063 * lisp.h (make_lisp_ptr): New macro to replace XSET.
1064 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
1067 2012-09-09 Eli Zaretskii <eliz@gnu.org>
1069 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
1070 left fringe if the window has a left margin. This avoids leaving
1071 traces of the cursor because its leftmost pixel is not drawn over.
1073 * dispnew.c (update_window_line): When the left margin area of a
1074 screen line is updated, set the redraw_fringe_bitmaps_p flag of
1075 that screen line. (Bug#12277)
1077 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
1079 Assume C89 or later for math functions (Bug#12381).
1080 This simplifies the code, and makes it a bit smaller and faster,
1081 and (most important) makes it easier to clean up signal handling
1082 since we can stop worring about floating-point exceptions in
1083 library code. That was a problem before C89, but the problem
1084 went away many years ago on all practical Emacs targets.
1085 * data.c, image.c, lread.c, print.c:
1086 Don't include <math.h>; no longer needed.
1087 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
1088 might be autoconfigured, as that never happens.
1090 * doprnt.c (DBL_MAX_10_EXP):
1091 * print.c (DBL_DIG):
1092 Remove. C89 or later always defines these.
1093 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
1094 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
1095 (arith_error, domain_error, domain_error2):
1096 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
1097 no longer needed -- we simply return what C returns. All uses removed.
1098 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
1100 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
1101 Remove. All uses expanded, as these macros are no longer used
1102 more than once and are now more trouble than they're worth.
1103 (Ftan): Use tan, not sin / cos.
1104 (Flogb): Assume C89 frexp.
1105 (fmod_float): Assume C89 fmod.
1106 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
1107 (init_floatfns): Remove. All uses removed.
1109 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
1111 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
1112 compositeToPoint for OSX < 10.6 (Bug#12390).
1114 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
1116 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
1117 This produces more-accurate results.
1119 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
1121 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
1122 changes (Bug#12088).
1124 2012-09-08 Chong Yidong <cyd@gnu.org>
1126 * syntax.c (Fstring_to_syntax): Doc fix.
1128 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
1130 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
1131 in the internal border.
1132 (x_set_window_size): Remove static variables and their usage.
1133 (ns_redraw_scroll_bars): Fix NSTRACE arg.
1134 (ns_after_update_window_line, ns_draw_fringe_bitmap):
1135 Remove fringe/internal border adjustment (Bug#11052).
1136 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
1137 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
1138 (ns_fix_rect_ibw): Remove.
1139 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
1140 (ns_dumpglyphs_box_or_relief): Ditto.
1141 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
1143 (ns_dumpglyphs_image): Ditto.
1144 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
1146 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
1147 their usage. Add fringe_extended_p and its use as in other terms.
1148 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
1149 scroll bar was removed.
1150 (updateFrameSize): New function.
1151 (windowDidResize): Move code to updateFrameSize and call it.
1153 * nsterm.h (EmacsView): Add updateFrameSize.
1155 2012-09-07 Chong Yidong <cyd@gnu.org>
1157 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
1159 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
1161 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
1163 More signal-handler cleanup (Bug#12327).
1164 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
1165 Problem introduced when merging patches. Noted by Eli Zaretskii in
1166 <http://bugs.gnu.org/12327#67>.
1167 * floatfns.c: Comment fix.
1168 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
1169 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
1170 and anyway the declaration is harmless even if SIGDANGER is not defined.
1171 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
1172 defined BROKEN_FIONREAD). systty.h formerly did this, but other
1173 source files not surprisingly expected syssignal.h to define, or
1174 not define, SIGIO, and it's cleaner to do it that way, for consistency.
1175 Include <sys/ioctl.h>, for FIONREAD.
1176 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
1177 This eliminates a problem whereby other files mysteriously had
1178 to include "syssignal.h" before including "systty.h" if they
1179 wanted to use "#ifdef SIGIO".
1181 2012-09-07 Eli Zaretskii <eliz@gnu.org>
1183 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
1185 * w32.c (sigemptyset): Empty the set.
1186 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
1188 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
1190 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
1192 * alloc.c (mark_buffer): Revert unsafe marking optimization.
1193 (mark_object): Likewise for frame objects.
1195 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
1197 * syssignal.h (handle_on_main_thread): Always declare,
1198 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
1199 This ports to platforms without HAVE_PTHREAD.
1201 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
1203 Signal-handler cleanup (Bug#12327).
1204 Emacs's signal handlers were written in the old 4.2BSD style with
1205 sigblock and sigmask and so forth, and this led to some
1206 inefficiencies and confusion. Rewrite these to use
1207 pthread_sigmask etc. without copying signal sets around. Also,
1208 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
1209 'signal', and instead use functions that do not attempt to take
1210 over the system name space. This patch causes Emacs's text
1211 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
1212 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
1213 Do not include <signal.h> or "syssignal.h", as these
1214 modules do not use signals.
1215 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
1216 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
1217 Do not include <signal.h>, as "syssignal.h" does that for us now.
1218 * atimer.c (sigmask_atimers): New function.
1219 (block_atimers, unblock_atimers): New functions,
1220 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
1222 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
1223 no longer needed here.
1224 * emacs.c (main): Inspect existing signal handler with sigaction,
1225 so that there's no need to block and unblock SIGHUP.
1226 * sysdep.c (struct save_signal): New member 'action', replacing
1227 old member 'handler'.
1228 (save_signal_handlers, restore_signal_handlers):
1229 Use sigaction instead of 'signal' to save and restore.
1230 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
1231 New function. All users of 'signal' modified to use set_sighandler
1232 if they're writeonly, and to use sys_signal if they're read+write.
1233 (emacs_sigaction_init, forwarded_signal): New functions.
1234 (sys_signal): Remove. All uses replaced by calls to sigaction
1235 and emacs_sigaction_init, or by direct calls to 'signal'.
1236 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
1237 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
1238 all uses replaced by pthread_sigmask etc. calls.
1239 * syssignal.h: Include <signal.h>.
1240 (emacs_sigaction_init, forwarded_signal): New decls.
1241 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
1242 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
1243 (sigmask, sys_sigmask): Remove; no longer needed.
1244 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
1245 (sigblock, sigunblock, sigfree):
1246 (sigsetmask) [!defined sigsetmask]:
1247 Remove. All uses replaced by pthread_sigmask.
1248 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
1249 no longer need to be replaced, and its typical old uses
1250 are now done via emacs_sigaction_init and sigaction.
1251 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
1252 (sys_sigdel): Remove; unused.
1253 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
1255 2012-09-06 Eli Zaretskii <eliz@gnu.org>
1257 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
1258 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
1260 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
1262 Explicitly mark buffer_defaults and buffer_local_symbols.
1263 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
1264 mark_local_symbols here.
1265 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
1266 since special buffers aren't marked here any more.
1267 (allocate_buffer): Chain new buffer with all_buffers here...
1268 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
1270 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
1271 (syms_of_buffer): Remove staticpro of the above.
1272 (init_buffer_once): Set names for buffer_defaults and
1273 buffer_local_symbols.
1275 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
1277 Use bool for booleans in font-related modules.
1278 * font.c (font_intern_prop, font_style_to_value)
1279 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
1280 (generate_otf_features, font_check_otf_features, font_check_otf)
1281 (font_match_p, font_list_entities, font_at):
1282 * fontset.c (fontset_id_valid_p, reorder_font_vector
1283 (fontset_find_font, Fset_fontset_font)
1284 (face_suitable_for_char_p) [0]:
1285 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
1286 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
1287 (m17n_flt_initialized, ftfont_shape_by_flt):
1288 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
1289 * nsfont.m (nsfont_draw):
1290 * w32font.c (w32font_draw):
1291 * w32term.c (x_draw_glyphless_glyph_string_foreground):
1292 Use bool for booleans.
1293 * font.h: Adjust to above API changes.
1294 (struct font, struct font_driver, struct font_driver_list):
1295 Use bool for booleans.
1296 (struct font): Remove useless member encoding_type.
1298 * fontset.c, xftfont.c: Omit unnecessary static decls.
1300 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
1302 * alloc.c (mark_object): Revert window marking code
1303 since it's unsafe for the Fset_window_configuration.
1305 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
1307 Fix race conditions with signal handlers and errno (Bug#12327).
1308 Be more systematic about preserving errno whenever a signal
1309 handler returns, even if it's not in the main thread. Do this by
1310 renaming signal handlers to distinguish between signal delivery
1311 and signal handling. All uses changed.
1312 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
1313 * data.c (deliver_arith_signal): Rename from arith_error.
1314 * dispnew.c (deliver_window_change_signal): Rename from
1315 window_change_signal.
1316 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
1317 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
1318 * keyboard.c (deliver_input_available_signal): Rename from
1319 input_available_signal.
1320 (deliver_user_signal): Rename from handle_user_signal.
1321 (deliver_interrupt_signal): Rename from interrupt_signal.
1322 * process.c (deliver_pipe_signal): Rename from send_process_trap.
1323 (deliver_child_signal): Rename from sigchld_handler.
1324 * atimer.c (handle_alarm_signal):
1325 * data.c (handle_arith_signal):
1326 * dispnew.c (handle_window_change_signal):
1327 * emacs.c (handle_fatal_signal, handle_danger_signal):
1328 * keyboard.c (handle_input_available_signal):
1329 * keyboard.c (handle_user_signal, handle_interrupt_signal):
1330 * process.c (handle_pipe_signal, handle_child_signal):
1331 New functions, with the actual signal-handling code taken from the
1332 original respective signal handlers, sans the sporadic attempts to
1333 preserve errno, since that's now done by handle_on_main_thread.
1334 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
1335 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
1336 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
1338 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
1339 Move initialization of main_thread to sysdep.c's init_signals.
1340 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
1341 our usage, and simplifies the mainline code.
1342 (record_child_status_change): New static function, as a helper
1343 for handle_child_signal, and with most of the old child handler's
1345 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
1346 (handle_child_signal): Use the above.
1347 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
1348 Moved here from emacs.c.
1349 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
1350 code moved here from emacs.c's main function.
1351 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
1352 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
1353 This lets callers save and restore errno properly.
1355 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
1357 Remove redundant or unused things here and there.
1358 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
1359 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
1360 * editfns.c (Fcompare_buffer_substrings): Likewise.
1361 * frame.h (struct terminal, struct font_driver_list):
1362 Remove redundant declarations.
1363 * window.h (Qleft, Qright): Likewise.
1365 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
1367 Do not mark objects from deleted buffers, windows and frames.
1368 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
1369 (mark_object): Likewise for windows and frames.
1371 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
1373 * alloc.c (valid_lisp_object_p): Treat killed buffers,
1374 buffer_defaults and buffer_local_symbols as valid objects.
1375 Return special value to denote them.
1377 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
1379 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
1380 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
1381 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
1382 (file_name_absolute_p, Fsubstitute_in_file_name):
1383 (check_executable, check_writable, Ffile_accessible_directory_p)
1384 (Fset_file_selinux_context, Fdefault_file_modes)
1385 (Finsert_file_contents, choose_write_coding_system)
1386 (Fwrite_region, build_annotations, a_write, e_write)
1388 * filelock.c (boot_time_initialized, get_boot_time)
1389 (get_boot_time_1, lock_file_1, within_one_second):
1390 * floatfns.c (in_float):
1391 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
1392 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
1393 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
1394 * lisp.h (struct Lisp_Hash_Table.cmpfn):
1395 * window.c (compare_window_configurations):
1396 Use bool for booleans.
1397 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
1398 (Fdefault_file_modes): Now mode_t, not int, for modes.
1399 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
1400 (internal_delete_file): Now returns void, not a (boolean) int,
1401 since nobody was looking at the return value.
1402 * lisp.h, window.h: Adjust to above API changes.
1404 * xdisp.c (set_message): Simplify and reindent last change.
1406 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
1408 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
1410 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
1412 * eval.c (call_debugger): Make the function non-static so that we
1413 can call it from set_message.
1415 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
1416 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
1418 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
1420 Give more-useful info on a fatal error (Bug#12328).
1421 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
1422 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
1423 of doing the work ourselves.
1424 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
1425 do most of the work.
1426 (fatal_error_backtrace): New function, taken from the guts
1427 of the old fatal_error_signal, but with a new option to output
1429 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
1430 info about the signal than just its number.
1431 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
1432 * sysdep.c: Include <execinfo.h>
1433 (emacs_backtrace): New function, taken partly from the previous
1434 code of the 'die' function.
1435 (emacs_abort): Call fatal_error_backtrace rather than abort.
1437 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
1439 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
1440 eager (load-time) macro-expansion.
1441 * lisp.mk (lisp): Add macroexp.
1443 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
1445 Simplify redefinition of 'abort' (Bug#12316).
1446 Do not try to redefine the 'abort' function. Instead, redo
1447 the code so that it calls 'emacs_abort' rather than 'abort'.
1448 This removes the need for the NO_ABORT configure-time macro
1449 and makes it easier to change the abort code to do a backtrace.
1450 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
1451 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
1452 Remove; sysdep.c's emacs_abort now takes its place.
1453 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
1454 'abort' changed to use 'emacs_abort'.
1455 * msdos.c (dos_abort) [defined abort]: Remove; not used.
1456 (abort) [!defined abort]: Rename to ...
1457 (emacs_abort): ... new name.
1458 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
1459 the place of the old 'abort' in emacs.c.
1460 * w32.c, w32fns.c (abort): Do not #undef.
1461 * w32.c (emacs_abort): Rename from w32_abort.
1463 2012-09-04 Eli Zaretskii <eliz@gnu.org>
1465 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
1466 offsets[j].dv, since the y axis of the screen coordinates points
1467 down, while the y axis of the font definition coordinates points
1468 up. This fixes display of Arabic diacritics such as KASRA and
1469 KASRATAN. (Bug#11860)
1471 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
1473 Be more systematic about _setjmp vs setjmp.
1474 * alloc.c (test_setjmp, mark_stack):
1475 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
1476 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
1477 (png_load, my_error_exit, jpeg_load):
1478 * process.c (send_process_trap, send_process):
1479 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
1480 The underscored versions are up to 30x faster on some hosts.
1481 Formerly, the code used setjmp+longjmp sometimes and
1482 _setjmp+_longjmp at other times, with no particular reason to
1483 prefer setjmp+longjmp.
1485 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
1487 Fix minor problem found by static checking.
1488 * buffer.c (Fdelete_all_overlays): Return nil.
1490 2012-09-03 Martin Rudalics <rudalics@gmx.at>
1492 * buffer.c (Fdelete_all_overlays): New function.
1494 2012-09-03 Chong Yidong <cyd@gnu.org>
1496 * gtkutil.c: Add extern decl for Qxft.
1498 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>

1512 All callers changed.
1513 * eval.c (interactive_p): Omit always-true boolean argument
1514 EXCLUDE_SUBRS_P. All callers changed.
1515 * dispextern.h, lisp.h: Reflect above API changes.
1516 * firstfile.c (dummy): Use the address of 'main', whose signature
1517 won't change, instead of the address of 'initialize', whose
1518 signature just changed from int to bool.
1519 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
1520 * msdos.c (fatal_error_in_progress): ... from here.
1521 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
1523 (redisplay_internal, unwind_redisplay): Simply clear
1524 REDISPLAYING_P when unwinding, instead of saving its previous,
1525 always-false value and then restoring it.
1527 Clean up some extern decls.
1528 Mostly, this hoists extern decls out of .c files and into .h files.
1529 That way, we're more likely to catch errors if the interfaces change.
1530 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
1531 declare xg_mark_data.
1532 * dispextern.h (x_frame_parm_handlers):
1534 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)

1548 * widget.c (free_frame_faces):
1549 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
1550 * xfont.c (x_clear_errors):
1551 * xterm.c (x_frame_parm_handlers):
1552 Remove now-redundant extern decls.
1553 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
1554 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
1556 * xfaces.c: Remove unnecessary static decls.
1557 * xterm.c (updating_frame): Remove decl of nonexistent object.
1559 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
1560 when building globals.h, as the objects that are not built on
1561 this host are not needed to compile C files on this host.
1563 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
1565 * gtkutil.h: Remove prototype for x_wm_set_size_hint.

1578 (format_time_string, general_insert_function)
1579 (make_buffer_string, make_buffer_string_both)
1580 (Fsubst_char_in_region, Ftranslate_region_internal, Fformat):

1592 (set_intervals_multibyte_1, set_intervals_multibyte):
1593 * keyboard.c (decode_timer):
1594 Use bool for boolean.
1595 * intervals.h, lisp.h, systime.h: Reflect above API changes.
1596 * editfns.c (struct info): Use 1-bit unsigned bitfields for booleans.
1598 2012-09-02 Chong Yidong <cyd@gnu.org>
1600 * keymap.c (push_key_description): Print M-TAB as C-M-i
1603 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
1605 * makefile.w32-in (CCL_H, W32FONT_H): New macros.
1606 (ATIMER_H, FONT_H, $(BLD)/alloc.$(O), $(BLD)/callproc.$(O))

1613 2012-09-01 Eli Zaretskii <eliz@gnu.org>
1615 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
1616 more than one grapheme cluster passed to the shaper: compute the
1617 offset adjustment values separately for each cluster. (Bug#11860)
1619 * image.c: Restore mistakenly removed inclusion of w32.h. Without
1620 it, GCC doesn't see prototypes of w32_delayed_load, and complains
1621 about implicit conversions from integer to pointer.
1623 2012-09-01 Daniel Colascione <dancol@dancol.org>
1625 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
1626 system used too early.
1628 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
1630 Better seed support for (random).

1663 Define FRAME_X_SCREEN, FRAME_X_VISUAL.
1665 * menu.c: Include TERM_HEADER instead of listing all possible
1666 window-system headers.
1668 * keyboard.h: Declare ignore_mouse_drag_p whenever we have a
1671 * keyboard.c: Include TERM_HEADER instead of listing all possible
1672 window-system headers.
1674 * image.c: Include TERM_HEADER instead of listing all possible
1675 window-system headers. Declare Vlibrary_cache when compiling for
1678 * gtkutil.h (xg_list_node_): Include xterm.h to pick up needed
1679 window system declarations.
1681 * frame.h: Move common functions here: set_frame_menubar,
1682 x_set_window_size, x_sync, x_get_focus_frame,
1683 x_set_mouse_position, x_set_mouse_pixel_position,
1684 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

1708 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
1710 Remove mark_ttys function and fix tty_display_info initialization.
1711 * lisp.h (mark_ttys): Remove prototype.
1712 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
1713 to mark_ttys because all possible values of 'top_frame' slot are
1714 the frames which are reachable from Vframe_list.
1715 * term.c (mark_ttys): Remove.
1716 (init_tty): Safely initialize 'top_frame' slot with Qnil.
1718 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>

1723 'auto_raise', 'auto_lower', 'no_split', 'explicit_name',
1724 'window_sizes_changed', 'mouse_moved' and 'pointer_invisible'
1725 bitfields from unsigned char to unsigned.

1738 2012-08-30 Paul Eggert <eggert@cs.ucla.edu>
1740 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
1741 for GCC 4.7.1 x86-64.
1743 2012-08-30 Glenn Morris <rgm@gnu.org>
1745 * lread.c (init_lread): For out-of-tree builds, only add the
1746 source directory's site-lisp dir to the load-path if it exists,
1747 consistent with in-tree builds. (Bug#12302)
1749 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>
1751 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize

1760 (addString:row:): Remove return self, declare return value as void.
1761 (addSplit): Remove return self, declare return value as void.
1762 (clicked:): Remove return self, declare return value as void.
1763 Set dialog_return to button_values[seltag]. Code formatting change.
1764 (initFromContents:isQuestion:): Adjust call to process_dialog.
1765 Code formatting change.
1766 (timeout_handler:): Set timer_fired to YES.
1767 (runDialogAt:): Set timer_fired to NO.
1768 Handle click on close button as quit.
1770 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
1771 Add window_closed and button_values. Add void as return value for
1772 add(Button|String|Split). addButton takes int instead of Lisp_Object.
1773 Add process_dialog as new member.
1775 2012-08-28 Eli Zaretskii <eliz@gnu.org>
1777 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it
1778 is not one of the heaps we manage. (Bug#12242)

1820 2012-08-27 Paul Eggert <eggert@cs.ucla.edu>
1822 * dispnew.c: Use bool for boolean.

1837 (do_pending_window_change, change_frame_size)
1838 (change_frame_size_1, sit_for):
1839 Use bool for boolean.
1840 (clear_glyph_matrix_rows): Rename from enable_glyph_matrix_rows,
1841 and remove last int (actually boolean) argument, which was always 0.
1842 All callers changed.
1843 * dispextern.h, frame.h, lisp.h: Reflect above API changes.
1844 * dispextern.h (struct composition_it): Use bool for boolean.
1845 (struct glyph_matrix): Don't assume buffer sizes can fit in 'int'.
1846 (struct bidi_it): Use unsigned:1, not int, for boolean prev_was_pdf.
1847 * dired.c (file_name_completion):
1848 Use bool for boolean. (This was missed in an earlier change.)
1850 2012-08-27 Martin Rudalics <rudalics@gmx.at>
1852 * window.c (Fset_window_configuration): Revert first part of
1855 2012-08-27 Jan Djärv <jan.h.d@swipnet.se>
1857 * nsterm.h (NSPanel): New class variable dialog_return.
1859 * nsmenu.m (initWithContentRect:styleMask:backing:defer:):
1860 Initialize dialog_return.
1861 (windowShouldClose:): Use stop instead of stopModalWithCode.
1862 (clicked:): Ditto, and also set dialog_return (Bug#12258).
1863 (timeout_handler:): Use stop instead of abortModal. Send a dummy
1865 (runDialogAt:): Make ret Lisp_Object. Set it from dialog_return when
1868 2012-08-27 Paul Eggert <eggert@cs.ucla.edu>
1870 * composite.c, data.c, dbusbind.c, dired.c: Use bool for booleans.

1880 Use bool for booleans.
1881 * dired.c (file_name_completion):
1882 * process.h (fd_callback):
1883 Omit int (actually boolean) argument. It wasn't being used.
1885 * composite.h, lisp.h: Reflect above API changes.
1887 * cmds.c, coding.c: Use bool for booleans.
1888 * cmds.c (move_point, Fself_insert_command):

1908 (Fset_coding_system_priority):
1909 * fileio.c (Finsert_file_contents):
1910 Use bool for booleans.
1911 * coding.h, lisp.h: Reflect above API changes.
1912 * coding.c: Remove unnecessary static function decls.
1913 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
1914 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
1915 not a boolean 'int', since callers never look at the return value.
1916 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
1917 * coding.h (decoding_buffer_size, encoding_buffer_size)
1918 (emacs_mule_string_char): Remove unused extern decls.
1919 (struct iso_2022_spec, struct coding_system):
1920 Use 'unsigned int : 1' for boolean fields, since there's more than one.
1921 (struct emacs_mule_spec): Remove unused field 'full_support'.
1922 All initializations removed.
1923 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
1925 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
1927 Fix spare memory change (Bug#12286).
1928 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
1929 (valid_lisp_object_p): Likewise.
1931 2012-08-27 Martin Rudalics <rudalics@gmx.at>
1933 * window.c (Fset_window_configuration): Record any window's old
1934 buffer if it's replaced (see Bug#8789). If the new current
1935 buffer doesn't appear in the selected window, go to its old
1938 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
1940 Special MEM_TYPE_SPARE to denote reserved memory.
1941 * alloc.c (enum mem_type): New memory type.
1942 (refill_memory_reserve): Use new type for spare memory.
1943 This prevents live_cons_p and live_string_p from incorrect
1944 detection of uninitialized objects from spare memory as live.
1946 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
1949 * Makefile.in (.PHONY): versioclean -> versionclean.
1951 Remove unused external symbols.
1952 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
1953 * window.c (Qwindow_valid_p, decode_valid_window):
1954 Now static, not extern.
1955 * data.c (Qinterval): Remove; unused.
1956 (syms_of_data): Do not define 'interval'.
1957 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
1958 * window.h (decode_valid_window):
1961 * character.c, charset.c, chartab.c: Use bool for booleans.
1962 * character.c (lisp_string_width, string_count_byte8)

1971 (char_table_set_range, optimize_sub_char_table)
1972 (map_sub_char_table):
1973 Use bool for boolean.
1974 * character.c (str_to_unibyte): Omit last boolean argument; it was
1975 always 0. All callers changed.
1976 * character.h, charset.h: Adjust to match previous changes.
1977 * character.h (char_printable_p): Remove decl of nonexistent function.
1978 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
1979 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
1980 are all boolean, so make them single-bit bitfields.
1982 * lisp.h (ASET): Remove attempt to detect side effects.
1983 It was meant to be temporary and it often doesn't work,
1984 because when IDX has side effects the behavior of IDX==IDX
1985 is undefined. See Stefan Monnier in
1986 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
1988 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
1990 * lisp.h (functionp): New function (extracted from Ffunctionp).
1991 (FUNCTIONP): Use it.
1992 * eval.c (Ffunctionp): Use it.
1994 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
1996 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
1997 as that's faster and simpler than static storage. Don't bother
1998 with the g_main_context_query overhead if g_main_context_pending
1999 says no events are pending.
2000 (gfds, gfds_size): Remove these static vars.
2001 (xgselect_initialize): Remove; no longer needed.
2002 All uses and decls removed.
2004 * emacs.c (fatal_error_signal_hook): Remove.
2005 All uses removed. This leftover from old code was always 0.
2007 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
2008 * casefiddle.c (casify_object, casify_region):
2009 * casetab.c (set_case_table):
2010 * category.c, category.h (word_boundary_p):
2011 * category.h (CHAR_HAS_CATEGORY):
2012 Use bool for booleans, instead of int.
2014 2012-08-25 Eli Zaretskii <eliz@gnu.org>
2016 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
2018 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
2020 On assertion failure, print backtrace if available.
2021 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
2022 (die) [ENABLE_CHECKING]: Print a backtrace if available.
2023 * Makefile.in (LIB_EXECINFO): New macro.
2026 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
2027 * bytecode.c (exec_byte_code):
2028 * callint.c (check_mark, Fcall_interactively):
2029 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
2030 (getenv_internal, sync_process_alive, call_process_exited):
2031 * lisp.h (USE_SAFE_ALLOCA):
2032 Use bool for booleans, instead of int.
2033 * lisp.h, process.h: Adjust prototypes to match above changes.
2034 * callint.c (Fcall_interactively): Don't assume the mark's
2035 offset fits in 'int'.
2037 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
2039 * buffer.c, buffer.h: Use bool for boolean.
2040 * buffer.c (reset_buffer_local_variables)
2041 (buffer_lisp_local_variables, Fset_buffer_modified_p)
2042 (Frestore_buffer_modified_p, Fset_buffer_multibyte):

2044 (overlay_touches_p, overlay_strings, Foverlay_put)
2045 (report_overlay_modification, call_overlay_mod_hooks):
2046 (mmap_enlarge, mmap_set_vars):
2047 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
2048 Use bool for booleans, instead of int.
2049 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
2050 since the 1-or-0 return value is always ignored anyway.
2051 (mmap_initialized_p):
2052 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
2053 * buffer.h, lisp.h: Adjust prototypes to match above changes.
2055 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
2057 * bidi.c: Use bool for boolean.
2058 This is a bit more readable, and makes the text segment of bidi.o
2059 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
2060 Presumably it's faster too.
2061 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
2063 (bidi_cache_find_level_change, bidi_cache_iterator_state)
2064 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
2065 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
2066 (bidi_explicit_dir_char, bidi_level_of_next_char)
2067 (bidi_find_other_level_edge, bidi_move_to_visually_next):
2068 Use bool for booleans, instead of int.
2069 * dispextern.h (bidi_init_it, bidi_paragraph_init)
2070 (bidi_unshelve_cache): Adjust decls to match code.
2072 2012-08-23 Martin Rudalics <rudalics@gmx.at>
2074 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
2077 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
2079 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
2080 * atimer.h: Include <stdbool.h>.
2082 2012-08-22 Dan Nicolaescu <dann@gnu.org>
2084 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
2085 compile time tests instead of run time tests on systems that do
2087 (FRAME_MAC_P): Remove leftover from deleted code.
2088 * frame.c (syms_of_frame): Remove leftover from deleted code.
2090 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
2092 * nsterm.m (insertText:): Don't clear modifiers if code is space.
2094 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
2096 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
2097 Otherwise, the compiler complains about (A?B:C) where B is void
2098 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
2099 (fontset_add): Return void, for FONTSET_ADD.
2101 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
2103 * alloc.c: Use bool for booleans.
2104 (gc_in_progress, abort_on_gc)
2105 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
2106 (dont_register_blocks) [GC_MALLOC_CHECK]:
2107 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
2108 (check_string_bytes, make_specified_string, memory_full)
2109 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
2110 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
2111 (mark_stack, valid_pointer_p, make_pure_string)
2112 (Fgarbage_collect, survives_gc_p, gc_sweep):
2113 Use bool for booleans, instead of int.
2114 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
2115 Remove unused local.
2116 * alloc.c (PURE_POINTER_P):
2117 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
2118 * editfns.c (Fformat):
2119 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
2121 * fns.c (sweep_weak_table):
2122 * lisp.h (suppress_checking, push_message, survives_gc_p)
2123 (make_pure_string, gc_in_progress, abort_on_gc):
2124 * lread.c (readchar, read1):
2125 * print.c (Fprin1_to_string):
2126 * xdisp.c (push_message):
2127 Use bool for booleans affected directly or indirectly by
2130 Make recently-introduced setters macros.
2131 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
2132 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
2133 (set_fontset_default, set_fontset_fallback): Rename from their
2134 upper-case counterparts, and make them functions rather than macros.
2135 This is more consistent with the other recently-introduced setters.
2136 These don't need to be inline, since they're local.
2138 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
2140 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
2141 the loop (Bug#12247).
2143 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
2145 * lisp.h (vcopy): Use memcpy rather than our own loop.
2146 This fixes a performance regression introduced by the recent
2147 addition of vcopy. This means 'vcopy' will need to be modified
2148 for a copying collector, but that's OK. Also, tighten the
2149 checking in the assertion.
2151 2012-08-21 Eli Zaretskii <eliz@gnu.org>
2153 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
2154 components for RTL text (Bug#11860). Adjust X-OFFSET of each
2155 non-base glyph for the width of the base character, according to
2156 what x_draw_composite_glyph_string_foreground expects.
2157 Generate WADJUST value according to composition_gstring_width's
2158 expectations, to produce correct width of the composed character.
2159 Reverse the sign of the DU offset produced by ScriptPlace.
2161 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
2163 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
2165 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
2167 Avoid direct writes to contents member of struct Lisp_Vector.
2168 * lisp.h (vcopy): New function to copy data into vector.
2169 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
2170 * fns.c (Ffillarray): Use ASET.
2171 * keyboard.c (timer_check_2): Use AREF and ASET.
2172 (append_tool_bar_item, Frecent_keys): Use vcopy.
2173 * lread.c (read_vector): Use ASET.
2174 * msdos.c (Frecent_doskeys): Use vcopy.
2175 * xface.c (Finternal_copy_lisp_face): Use vcopy.
2176 (Finternal_merge_in_global_face): Use ASET and vcopy.
2177 * xfont.c (xfont_list_pattern): Likewise.
2179 2012-08-21 Martin Rudalics <rudalics@gmx.at>
2181 * window.c (Fwindow_point): For the selected window always return
2182 the position of its buffer's point.
2183 (Fset_window_point): For the selected window always go in its
2184 buffer to the specified position.
2186 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
2188 Setter macros for fontsets.
2189 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
2190 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
2191 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
2194 2012-08-20 Glenn Morris <rgm@gnu.org>
2196 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
2197 Don't assume that `ln -f' works.
2199 2012-08-20 Eli Zaretskii <eliz@gnu.org>
2201 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
2202 and later about non-assignments with no effect. See discussion at
2203 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
2206 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
2208 Inline setter functions for Lisp_Objects slots of struct specbinding.
2209 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
2212 2012-08-20 Martin Rudalics <rudalics@gmx.at>
2214 * window.c (select_window): Always make selected window's buffer
2217 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
2219 Use AREF and ASET for docstrings of category tables.
2220 * category.h (CATEGORY_DOCSTRING): Use AREF.
2221 (SET_CATEGORY_DOCSTRING): Use ASET.
2222 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
2224 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
2226 Inline setter functions for hash table members.
2227 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
2228 (set_hash_hash, set_hash_index): Rename with _slot suffix.
2229 (set_hash_key_and_value, set_hash_index, set_hash_next)
2230 (set_hash_hash): New functions.
2231 * charset.c, fns.c: Adjust users.
2233 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
2235 Inline getter and setter functions for per-buffer values.
2236 * buffer.h (per_buffer_default, set_per_buffer_default)
2237 (per_buffer_value, set_per_buffer_value): New functions.
2238 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
2239 * buffer.c, data.c: Adjust users.
2241 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
2243 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
2245 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
2247 Rely on <config.h> + <unistd.h> to declare 'environ',
2248 as gnulib does this if the system doesn't.
2249 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
2250 Remove declaration. MS-Windows declares it on stdlib.h which is
2251 included by conf_post.h.
2252 * emacs.c (environ) [DOUG_LEA_MALLOC]:
2253 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.

2260 and avoid a gcc -Wmaybe-uninitialized diagnostic.
2262 2012-08-19 Chong Yidong <cyd@gnu.org>

2673 Use bool, not int, for Lisp booleans.
2674 This is more natural, and on my platform (GCC 4.7.1 x86-64) it

3126 (check_windows_init_file): Now external, not static.
3127 Use Vload_path as is, without adding anything, as this function is now
3128 called when Vload_path is already set up.
3130 * w32.h (check_windows_init_file): Add prototype.
3132 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build
3133 directory, ignore the /*/i386/ tail in Vinvocation_directory, for
3134 compatibility with Posix platforms.
3135 (main): Move the call to check_windows_init_file to here from
3137 (decode_env_path) [WINDOWSNT]: Expand the %emacs_dir%/ prefix, if
3138 any, in the DEFALT argument into the root of the Emacs build or
3139 installation tree, as appropriate.
3141 * callproc.c (init_callproc_1): Call decode_env_path instead of
3142 doing its equivalent by hand.
3143 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
3144 the code that sets Vexec_path run on MS-Windows.
3146 * lread.c (init_lread): Add comments to #ifdef's.
3148 * msdos.c (dos_set_window_size, IT_update_begin)
3149 (IT_frame_up_to_date, IT_set_frame_parameters): Use FVAR and WVAR
3150 instead of direct references.
3152 2012-08-04 Paul Eggert <eggert@cs.ucla.edu>
3154 Export DEFAULT_REHASH_* to GDB.
3155 * lisp.h (DEFAULT_REHASH_THRESHOLD, DEFAULT_REHASH_SIZE):
3156 Now constants, not macros.
3158 2012-08-03 Paul Eggert <eggert@cs.ucla.edu>
3160 Remove unnecessary casts involving pointers.
3161 These casts are no longer needed now that we assume C89 or later,
3162 since they involve casting to or from void *.
3163 * alloc.c (make_pure_string, make_pure_c_string, pure_cons)
3164 (make_pure_float, make_pure_vector):
3165 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP):

3173 * xselect.c (x_stop_queuing_selection_requests)
3174 (x_get_window_property, x_get_window_property_as_lisp_data):
3175 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
3176 Remove unnecessary pointer casts.
3177 * alloc.c (record_xmalloc): New function.
3178 * lisp.h (record_xmalloc): New decl.
3179 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
3180 more like a function. This is because the pointer cast is not
3181 needed. All uses changed.
3182 * print.c (print_string, print_error_message): Avoid length recalc.
3184 Improve fix for macroexp crash with debugging (Bug#12118).
3185 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
3186 ARRAY_MARK_FLAG when checking subscripts, because ASET is
3187 not supposed to be invoked from the garbage collector.
3188 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
3189 (gc_aset): New function, which is like ASET but can be
3190 used in the garbage collector.
3191 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)
3192 (set_hash_index): Use it instead of ASET.

3201 <g_b_init_create_symbolic_link>: New static flags.
3202 (globals_of_w32): Initialize them to zero.
3203 (GetSecurityInfo_Proc, CreateSymbolicLink_Proc): New typedefs.
3204 (map_w32_filename): Improve commentary. Simplify switch.
3205 (SYMBOLIC_LINK_FLAG_DIRECTORY): Define if not defined in system
3206 headers (most versions of MinGW w32api don't).
3207 (get_security_info, create_symbolic_link)
3208 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
3210 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
3211 in the argument file name.
3212 (sys_access): Call unc_volume_file_attributes only if
3213 GetFileAttributes fails with network-related error codes.
3214 (sys_rename): Diagnose renaming of a symlink when the user doesn't
3215 have the required privileges.
3216 (get_file_security_desc_by_name): Rename from
3217 get_file_security_desc.
3218 (stat_worker): New function, with most of the guts of 'stat', and
3219 with addition of handling of symlinks and support for 'lstat'.
3220 If possible, get file's attributes and security information by
3221 handle, not by name. Produce S_IFLNK bit for symlinks, when
3222 called from 'lstat'.
3223 (stat, lstat): New functions, call 'stat_worker'.
3224 (symlink, readlink, careadlinkat): Rewritten to create and resolve
3225 symlinks when the underlying filesystem supports them.
3227 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
3229 Fix macroexp crash on Windows with debugging (Bug#12118).
3230 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
3231 checking subscripts; problem introduced with the recent
3232 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
3233 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
3234 since it's used in non-static inline functions now.
3236 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
3237 Don't assume buffer size fits in 'int'. Remove unused local.
3239 Use C99-style 'extern inline' if available.

3251 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
3252 * alloc.c (LISP_INLINE):
3253 * buffer.c (BUFFER_INLINE):
3254 * category.c (CATEGORY_INLINE):
3255 * character.c (CHARACTER_INLINE):
3256 * charset.c (CHARSET_INLINE):
3257 * composite.c (COMPOSITE_INLINE):
3258 * dispnew.c (DISPEXTERN_INLINE):
3259 * sysdep.c (SYSTIME_INLINE):
3260 Define to EXTERN_INLINE, so that the corresponding functions
3261 are compiled into code.
3262 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
3263 (INLINE_HEADER_END): New macros.
3264 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

3284 hard-coding the path separator.
3286 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
3288 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
3289 This how ASET and AREF are supposed to work, and makes
3290 it easier to think about future improvements. See
3291 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
3292 * charset.h (set_charset_attr): New function.
3293 All lvalue-style uses of CHARSET_DECODER etc. changed to use it.
3294 * lisp.h (ASET): Rewrite so as not to use AREF in an lvalue style.

3708 enumeration constants, as PURE and HEAP are too general, and clash
3709 with other headers and sources, such as gmalloc.c and the
3710 MS-Windows system headers. All users changed.
3712 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
3714 Revert last save_excursion_save and save_excursion_restore changes.
3715 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

3728 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
3729 arms of an 'if', not using conditional expressions; otherwise GDB
3730 complains about the types in the unevaluated arm when the argument
3731 is an integer literal.
3732 (xgetint): Simplify expression.
3733 * alloc.c (gdb_make_enums_visible): New constant. This ports to
3734 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
3735 Zaretskii in <http://bugs.gnu.org/12036#13>.
3736 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
3737 needed now that we have gdb_make_enums_visible.
3738 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
3739 (enum enum_USE_LSB_TAG):
3740 New enum types, packaging up enums that need to be exported to GDB.

3782 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
3783 emacs.c, as this is a more-suitable home. Had this been done earlier
3784 the fix for 12036 would have avoided some of the problems noted in
3785 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
3786 would have been more obvious.
3787 * emacs.c: Do not include <verify.h>; no longer needed.
3788 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
3789 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
3790 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):

3796 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
3797 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
3798 not be usable in #if. This simplifies things.
3800 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
3802 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.

3807 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
3808 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
3809 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
3810 Adjust to changes in lisp.h and emacs.c, by using
3811 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
3812 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
3813 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
3814 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
3815 instead of gdb_valbits.
3816 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
3817 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
3818 instead of gdb_array_mark_flag.
3819 (xboolvector): Get size from $->size, not $->header.size.
3820 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
3821 (xreload, hook-run, hookpost-run): Remove.
3822 * emacs.c: Include <verify.h>.
3823 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
3824 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
3826 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
3827 (gdb_USE_LSB_TAG): New enum constants.
3828 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
3829 Also define these as enum constants, so they're visible to GDB.
3830 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
3831 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
3832 as constants, so they're visible to GDB.

3835 Now enum constants, not macros, so they're visible to GDB.
3836 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
3837 more convenient now. All uses changed.
3838 (VALMASK) [USE_LSB_TAG]: Also define in this case.

3848 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
3849 add argument, tune behavior, and adjust all callers.
3851 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
3853 Use typedef for EMACS_INT, EMACS_UINT.
3854 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
3855 than macros. This simplifies debugging in the usual case, since
3856 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
3857 and it allows expressions involving EMACS_INT casts.
3858 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
3860 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

3872 Adjust buffer text indirection counters at the end of Fkill_buffer.
3873 * buffer.c (Fkill_buffer): Adjust indirection counters when the
3874 buffer is definitely dead. This should really fix an issue reported
3875 by Christoph Scholtes again. (Bug#12007).
3876 (init_buffer_once): Initialize indirection counters of
3877 buffer_defaults and buffer_local_symbols (for sanity and safety).
3879 2012-07-24 Eli Zaretskii <eliz@gnu.org>
3881 * xdisp.c (init_iterator): Don't compute dimensions of truncation
3882 and continuation glyphs on tooltip frames, leave them at zero.

3910 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
3912 Swap buffer text indirection counters in Fbuffer_swap_text.
3913 * buffer.c (Fbuffer_swap_text): Swap indirections too.
3914 This avoids crash reported by Christoph Scholtes at
3915 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
3917 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
3919 * nsmenu.m (Popdown_data): New struct.

3924 and autorelease them. Also autorelease img and matrix (Bug#12005).
3925 (dealloc): Remove (Bug#12005).

3942 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
3944 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
3945 as it's limited by the amount of memory, not by INT_MAX.
3947 2012-07-21 Eli Zaretskii <eliz@gnu.org>
3949 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
3950 in special-event-map. See the discussion at

4673 * s/aix4-2.h (unix): Remove; no longer needed.
4675 EMACS_TIME simplification (Bug#11875).
4676 This replaces macros (which typically do not work in GDB)

4678 The functional style also makes code easier to read and maintain.
4679 * systime.h: Include <sys/time.h> on all hosts, not just if
4680 WINDOWSNT, since 'struct timeval' is needed in general.

4693 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
4694 not functions. All uses rewritten to use the following, respectively:
4695 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
4696 (add_emacs_time, sub_emacs_time): New functions.
4697 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.

4720 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
4721 Prefer snprintf to strncpy.
4722 * nsterm.m (ns_term_init):
4723 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
4724 * nsterm.m (ns_term_init):
4725 Avoid the need for strncpy, by using build_string or
4726 make_unibyte_string directly. Use dtoastr, not snprintf.
4727 * process.c (Fmake_network_process): Diagnose service names that
4728 are too long, rather than silently truncating them or creating
4729 non-null-terminated names.

4736 2012-07-10 Glenn Morris <rgm@gnu.org>
4738 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
4739 Clarify fallback case.
4741 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>

4745 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
4746 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
4747 where argument type is known to be a Lisp_Cons.

4802 O_RDONLY already includes it).
4804 Stop ns builds setting the EMACSLOADPATH environment variable.
4805 * nsterm.m (ns_load_path): Rename from ns_init_paths.
4806 Now it does not set EMACSLOADPATH, just returns the load-path string.

4808 * lread.c [HAVE_NS]: Include nsterm.h.
4809 (init_lread) [HAVE_NS]: Use ns_load_path.

4819 (ns_init_paths): Do not set EMACSPATH.

4879 Move marker debugging code under MARKER_DEBUG.
4880 * marker.c (MARKER_DEBUG): Move marker debugging code under
4881 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
4882 for bootstrap with --enable-checking (~3x slowdown reported

4906 * xdisp.c (display_line): Avoid warning about implicit declaration
4909 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
4911 * lisp.h: Remove empty conditional.
4913 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
4915 * lread.c (load_path_check): Now static.
4917 Fix some minor --with-ns problems found by static checking.
4918 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
4919 (x_set_font) [!HAVE_X_WINDOWS]:
4920 * image.c (xpm_load_image) [HAVE_NS]:
4921 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
4922 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
4923 Remove unused local.
4924 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
4925 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
4926 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
4927 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
4928 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
4929 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
4930 Fix pointer signedness problem.
4931 * xfaces.c (FRAME_X_FONT_TABLE):
4932 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
4934 2012-07-07 Glenn Morris <rgm@gnu.org>
4936 * lread.c (load_path_check): New function, split from init_lread.
4937 (init_lread): Reorganize. Motivation:
4938 If EMACSLOADPATH is set, check/warn about that rather than the
4939 defaults, which we are not going to use. Hence we can remove
4940 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
4941 Don't warn if site-lisp directories are missing.
4942 If not installed, start from a blank load-path, since
4943 PATH_LOADSEARCH refers to the eventual installation directories.
4945 2012-07-07 Eli Zaretskii <eliz@gnu.org>
4947 Support truncation and continuation glyphs on GUI frames, when
4948 fringes are disabled. (Bug#11832)
4949 * xdisp.c (init_iterator): Get dimensions of truncation and
4950 continuation glyphs even if on GUI frames.
4951 Adjust it->last_visible_x on GUI frames when the left or right fringes,
4952 or both, are absent.
4953 (start_display, move_it_in_display_line_to): Handle the case of a
4954 GUI frame without a fringe to display continuation or truncation
4956 (insert_left_trunc_glyphs): Support GUI frames: make sure
4957 truncation glyphs overwrite enough glyphs from the current line to
4958 have sufficient space in pixels.
4959 (display_line): Support truncation and continuation glyphs on GUI
4960 frames. If some spare pixels are left on the line after inserting
4961 the truncation glyphs, fill that space with a stretch glyph of a
4962 suitably computed width.
4964 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
4965 produce_glyphs, to support GUI sessions.
4967 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
4969 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
4971 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
4973 Do not require float-time's arg to fit in time_t (Bug#11825).
4974 This works better on hosts where time_t is unsigned, and where
4975 float-time is applied to the (negative) difference between two times.
4976 * editfns.c (decode_time_components): Last arg is now double *,
4977 not int *, and means to store all the result as a double, without
4978 worrying about whether the seconds part fits in time_t.
4979 All callers changed.
4980 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
4981 All callers changed.
4982 (Ffloat_time): Do not fail merely because the specified time falls
4983 outside of time_t range.
4985 2012-07-07 Glenn Morris <rgm@gnu.org>
4987 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
4988 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
4989 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
4991 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
4993 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
4994 Update dependencies.
4996 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
4998 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
5000 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
5001 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
5002 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
5003 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
5004 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
5005 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
5007 * xfont.c (compare_font_names): Redo to omit the need for casts.
5009 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
5011 * xfns.c (Fx_change_window_property): Doc fix.
5012 * w32fns.c (Fx_change_window_property): Doc fix.
5014 * w32fns.c (Fx_window_property): Accept the same arguments as the
5015 X Windows version. Doc fix.
5016 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
5018 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
5019 Eli Zaretskii <eliz@gnu.org>
5021 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
5022 Windows-specific code from nt/config.nt moved here.
5023 Obsolete settings removed.
5025 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
5027 * process.c: Avoid unnecessary calls to gettime.
5028 (wait_reading_process_output): Don't get the time of day
5029 when gobbling data immediately and not waiting, as there's no need
5030 for it in that case. This removes a FIXME.
5032 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
5034 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
5035 is defined (Bug#11768).
5037 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
5039 Fix marker debugging code.
5040 * marker.c (byte_char_debug_check): Do not perform the check
5041 if buffer is not multibyte.
5042 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
5043 Call byte_char_debug_check with correct arguments.
5045 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
5047 Compile marker debugging code only if ENABLE_CHECKING is defined.
5048 * marker.c (byte_char_debug_check, count_markers):
5049 Use only if ENABLE_CHECKING is defined.
5050 (byte_debug_flag): Remove.
5051 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
5052 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
5054 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
5056 Avoid code repetition in marker-related functions.
5057 * marker.c (attach_marker): New function.
5058 (Fset_marker, set_marker_restricted, set_marker_both)
5059 (set_marker_restricted_both): Use it.
5060 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
5061 Consistently rename charno to charpos.
5062 (marker_position): Add eassert.
5063 (marker_byte_position): Convert to eassert.
5065 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
5067 Simplify list operations in unchain_overlay and unchain_marker.
5068 * buffer.c (unchain_overlay): Simplify. Add comment.
5069 * marker.c (unchain_marker): Simplify. Fix comments.
5071 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
5073 Introduce fast path for the widely used marker operation.
5074 * alloc.c (build_marker): New function.
5075 * lisp.h (build_marker): New prototype.
5076 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
5077 * composite.c (autocmp_chars): Likewise.
5078 * editfns.c (buildmark): Remove.
5079 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
5080 (save_restriction_save): Use build_marker.
5081 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
5082 * window.c (save_window_save): Likewise.
5084 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
5086 Do not use Fdelete_overlay in delete_all_overlays
5087 to avoid redundant calls to unchain_overlay.
5088 * buffer.c (drop_overlay): New function.
5089 (delete_all_overlays, Fdelete_overlay): Use it.
5090 * minibuf.c (get_minibuffer): Fix comment.
5092 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
5094 Port to OpenBSD 5.1 amd64.
5095 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
5096 This is needed for OpenBSD, and should be harmless on all BSD systems.
5097 Also, include <sys/sysctl.h>, as it should be available on all
5098 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
5099 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
5100 use p_pid member, not kp_proc.pid.
5102 2012-07-06 Glenn Morris <rgm@gnu.org>
5104 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
5106 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
5108 More xmalloc and related cleanup.
5109 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
5110 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:
5111 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, fns.c:

5113 * gtkutil.c, image.c, keyboard.c, keymap.c, lread.c, macros.c, menu.c:
5114 * nsfns.m, nsfont.m, nsmenu.m, nsterm.m, print.c, process.c, ralloc.c:
5115 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:
5116 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
5117 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
5119 Omit needless casts involving void * pointers and allocation.
5120 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
5121 as the former is more robust if P's type is changed.
5122 Prefer xzalloc to xmalloc + memset 0.
5123 Simplify malloc-or-realloc to realloc.
5124 Don't worry about xmalloc returning a null pointer.
5125 Prefer xstrdup to xmalloc + strcpy.
5126 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
5128 * keyboard.c (apply_modifiers_uncached): Prefer local array to
5129 alloca of a constant.
5131 2012-07-05 Eli Zaretskii <eliz@gnu.org>
5133 * xdisp.c (display_line): Fix horizontal pixel coordinates when
5134 hscroll is larger than the line width. Fixes long and futile
5135 looping inside extend_face_to_end_of_line (on a TTY) producing
5136 glyphs that are not needed and thrown away.
5138 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
5140 * marker.c (set_marker_restricted_both): Simplify by using
5143 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
5145 * editfns.c (region_limit): Simplify by using clip_to_bounds.
5147 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
5149 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
5150 not defined (Bug#11768).
5151 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
5152 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
5153 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
5154 followed by gtk_box_set_homogeneous (Bug#11768).
5155 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
5156 (update_theme_scrollbar_width, xg_create_scroll_bar):
5157 Use gtk_scrollbar_new (Bug#11768).
5158 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
5159 (is_box_type): New function (Bug#11768).
5160 (xg_tool_item_stale_p): Call is_box_type.
5161 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
5162 with default display (Bug#11768).
5164 2012-07-05 Eli Zaretskii <eliz@gnu.org>
5166 * xdisp.c (window_hscroll_limited): New function.
5167 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
5168 coordinates when window's hscroll is set to insanely large
5171 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
5173 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
5174 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
5176 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
5179 * lisp.h (xzalloc): New prototype. Omit needless casts.
5180 * alloc.c (xzalloc): New function. Omit needless casts.
5181 * charset.c: Omit needless casts. Convert all calls to
5182 xmalloc with following memset to xzalloc.
5183 * dispnew.c: Likewise.
5184 * fringe.c: Likewise.
5185 * image.c: Likewise.

5232 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
5234 * fileio.c (time_error_value): Check the right error number.
5235 Problem reported by Troels Nielsen in
5236 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
5238 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
5240 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
5241 This should be fixed in a better way; see Eli Zaretskii in
5242 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
5243 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
5245 * fileio.c (time_error_value): Rename from special_mtime.
5246 The old name's problems were noted by Eli Zaretskii in
5247 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
5249 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
5250 This variable's comment says Emacs needs at least one GDB-visible
5251 symbol of type enum pvec_type, to work around GDB problems.
5252 The symbol's value doesn't matter.
5254 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
5255 that causes compilation to fail on pre-C99 compilers.
5257 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
5259 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
5260 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
5262 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
5264 * buffer.c (init_buffer_once): Fix initialization of
5265 headers for buffer_defaults and buffer_local_symbols.
5266 Reported by Juanma Barranquero <lekktu@gmail.com>.
5268 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
5270 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
5271 * lisp.h (enum pvec_type): Use fewer bits.
5272 (PSEUDOVECTOR_SIZE_BITS): New constant.
5273 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
5274 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
5275 change in pvec_type.
5276 (PSEUDOVECTOR_TYPEP): New macro.
5277 (TYPED_PSEUDOVECTORP): Use it.
5278 * fns.c (internal_equal): Adapt code to extract pvectype.
5279 * emacs.c (gdb_pvec_type): Update type.
5280 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
5281 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
5282 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
5283 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
5284 (sweep_vectors): Use it. Use local var `total_bytes' instead of
5285 abusing vector->header.next.nbytes.
5286 (live_vector_p): Use PVEC_TYPE.
5287 (mark_object): Adapt code to extract pvectype. Use switch.
5289 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
5291 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
5292 Tighten new eassert a bit.
5294 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
5296 Fix compilation with --enable-gcc-warnings and -O1
5298 * doprnt.c (doprnt): Change type of tem to int, initialize
5299 to avoid compiler warning. Add eassert.
5300 * search.c (simple_search): Initialize match_byte to avoid
5301 compiler warning. Add eassert.
5303 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
5305 Avoid weird behavior with large horizontal scrolls.
5306 Without this change, for example, large hscroll values would
5307 mess up Emacs's display on Fedora 15 x86, presumably due to
5308 overflows in int calculations in the display code.
5309 Also, if buffers had long lines, Emacs would freeze.
5310 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
5311 (set_window_hscroll): New function, containing the old guts of
5312 Fset_window_hscroll. Return the clipped value.
5313 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
5314 This avoids the need to check against PTRDIFF_MAX.
5316 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
5318 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
5320 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
5322 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
5324 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
5325 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
5326 since GCC 4.4.6 issues a bogus warning for them.
5328 Fix bugs in file timestamp newness comparisons.
5329 * fileio.c (Ffile_newer_than_file_p):
5330 * lread.c (Fload): Use full timestamp resolution of files,
5331 not just the 1-second resolution, so that files that are only
5332 slightly newer still count as newer.
5333 * fileio.c (Ffile_newer_than_file_p): Don't assume file
5334 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
5336 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
5338 * fileio.c: Improve handling of file time marker. (Bug#11852)
5339 (special_mtime): New function.
5340 (Finsert_file_contents, Fverify_visited_file_modtime):
5341 Use it to set special mtime values consistently.
5343 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
5345 * fileio.c (Finsert_file_contents): Properly handle st_mtime
5346 marker for non-existing file. (Bug#11852)
5348 2012-07-03 Glenn Morris <rgm@gnu.org>
5350 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
5351 and did not make it into globals.h).
5353 2012-07-03 Tom Tromey <tromey@redhat.com>
5355 * window.c (Fset_window_margins, Fset_window_fringes)
5356 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
5357 * textprop.c (Fprevious_property_change): No longer static.
5358 * syntax.c (Fsyntax_table_p): No longer static.
5359 * process.c (Fget_process, Fprocess_datagram_address): No longer

5399 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
5400 values which aren't power of 2.
5401 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
5402 Verify it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
5405 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
5407 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.

5411 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
5413 * alloc.c (allocate_vector_block): Remove redundant
5414 calls to mallopt if DOUG_LEA_MALLOC is defined.
5415 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
5416 avoid calls to mallopt if zero_vector is returned.
5418 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
5420 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
5421 is enabled, avoid dereferencing NULL current_sblock if
5424 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
5426 Cleanup basic buffer management.
5427 * buffer.h (struct buffer): Change layout to use generic vector
5428 marking code. Fix some comments. Change type of 'clip_changed'
5429 to bitfield. Remove unused #ifndef old.
5430 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
5431 (GET_OVERLAYS_AT): Fix indentation.

5436 * alloc.c (allocate_buffer): Adjust to match new layout of
5437 struct buffer. Fix comment.
5438 (mark_overlay): New function.

5440 Lisp area of struct buffer.
5441 (mark_object): Use it. Adjust marking of misc objects
5442 and related comments.
5444 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
5446 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
5447 wrapper that is not needed because the wrapped code is a no-op (zero
5448 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
5449 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
5451 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
5453 * alloc.c (mark_buffer): Simplify. Remove prototype.
5454 (mark_object): Add comment. Reorganize marking of vector-like
5455 objects. Use CHECK_LIVE for all vector-like objects except buffers
5456 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
5457 Avoid redundant calls to mark_vectorlike for bool vectors.
5459 2012-06-30 Glenn Morris <rgm@gnu.org>
5461 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
5463 * epaths.in (PATH_SITELOADSEARCH): New.
5464 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
5465 This is rather than relying on --enable-locallisppath elements
5466 having "site-lisp" in their names. (Bug#10208#25, 11658)
5468 2012-06-30 Eli Zaretskii <eliz@gnu.org>
5470 * w32proc.c (sys_select): Accept and ignore one more argument.
5472 * w32.c (emacs_gnutls_pull): Call select with one more argument.
5474 * sysselect.h [DOS_NT]: Don't include sys/select.h.
5475 (pselect) [!MS_DOS]: Redirect to sys_select.
5477 * sysdep.c: Don't include dos.h and dosfns.h.
5479 * process.c (sys_select):
5480 * msdos.c (sys_select): Accept one more argument and ignore it.
5482 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
5483 adapt data types and code to that.
5486 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
5487 which clashes with the gnulib function of the same name.
5489 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
5491 * font.c (font_style_to_value, font_style_symbolic)
5492 (font_prop_validate_style): Add type checks for values in
5495 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
5497 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
5500 2012-06-29 Eli Zaretskii <eliz@gnu.org>
5502 * xdisp.c (try_window_id): Undo last change.
5504 * w32.c (getwd): Adjust commentary about startup_dir.
5505 (init_environment): Always call sys_access, even in non-MSVC
5506 builds. Don't chdir to the directory of the Emacs executable.
5507 This undoes code from 1997 which was justified by the need to
5508 "avoid conflicts when removing and renaming directories". But its
5509 downside was that every relative file name was being interpreted
5510 relative to the directory of the Emacs executable, which can never
5511 be TRT. In particular, it broke sys_access when called with
5512 relative file names.
5513 (sys_access): Map GetLastError to errno.
5515 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
5517 * window.h (struct window): Change type of 'fringes_outside_margins'

5533 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
5535 * editfns.c (region_limit): Fix type mismatch.
5537 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
5539 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
5540 undefined. Convert from xassert to eassert.
5541 * nsmenu.m: Convert from xassert to eassert.

5557 * window.h (struct window): Change type of 'hscroll',
5558 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,

5560 Adjust users accordingly.
5561 * xdisp.c (try_cursor_movement): Replace type check with eassert.
5562 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
5563 from EMACS_INT to ptrdiff_t.

5639 * alloc.c (allocate_string): Omit intervals initialization.
5640 * alloc.c (make_uninit_multibyte_string): Initialize intervals

5699 a better opportunity to optimize away calls to strlen when the
5700 function is called with compile-time constant argument.
5701 * image.c (imagemagick_error): Convert to build_string.
5702 * w32proc.c (sys_spawnve): Likewise.

5705 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
5707 Use sprintf return value instead of invoking strlen on result.
5708 In the old days this wasn't portable, since some sprintf
5709 implementations returned char *. But they died out years ago and
5710 Emacs already assumes sprintf returns int.
5711 Similarly for float_to_string.
5712 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

5719 * xfns.c (syms_of_xfns):
5720 Use sprintf or float_to_string result to avoid need to call strlen.
5721 * data.c (Fnumber_to_string):
5722 Use make_unibyte_string, since the string must be ASCII.
5723 * lisp.h, print.c (float_to_string): Now returns int length.
5724 * term.c (produce_glyphless_glyph):
5725 Use sprintf result rather than recomputing it.
5727 Clean out last vestiges of the old HAVE_CONFIG_H stuff.

5760 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

5763 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
5765 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
5766 instead of truncating it to 63 (admittedly a generous limit).
5768 * process.c: Fix spelling and caps in comments.
5770 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>

5826 * keyboard.c (kbd_buffer_get_event):

5849 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
5850 Privately reported by Herbert J. Skuhra.
5851 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
5853 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,

5888 * sysdep.c [__FreeBSD__]: Fix recently-introduced typos.
5889 Privately reported by Herbert J. Skuhra.
5890 [__FreeBSD__]: Remove "*/" typo after "#include".
5891 (timeval_to_EMACS_TIME) [__FreeBSD__]: New static function.
5892 (TIMEVAL) [__FreeBSD__]: Now a static function rather than a macro.
5893 (TIMEVAL, system_process_attributes) [__FreeBSD__]:
5894 Don't assume EMACS_TIME and struct timeval are the same type.
5896 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
5898 Support higher-resolution time stamps (Bug#9000).
5899 The time stamps are only nanosecond-resolution at the C level,
5900 since that's the best that any real-world system supports now.
5901 But they are picosecond-resolution at the Lisp level, as that's
5902 easy, and leaves room for future OS improvements.
5904 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
5907 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
5908 Don't get current time unless it's needed.

5911 now provides it if it's absent.
5912 (start_atimer): Port to higher-res time stamps.
5913 Check for time stamp overflow. Don't get current time more
5914 often than is needed.
5916 * buffer.h (struct buffer): Buffer modtime now has high resolution.
5917 Include systime.h, not time.h.

5924 (struct image): Timestamp now has higher resolution.
5926 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
5927 has at least microseconds now. All uses removed.

5929 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
5930 (duration_to_sec_usec): Remove; no longer needed.

5941 Report an error if the time is invalid, rather than having the caller
5944 * fileio.c: Include <stat-time.h>
5945 (Fcopy_file): Copy higher-resolution time stamps.
5946 Prefer to set the time stamp via a file descriptor if that works.

5949 (Fvisited_file_modtime, Fset_visited_file_modtime):
5950 Support higher-resolution time stamps.
5952 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
5954 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
5956 * image.c (prepare_image_for_display, clear_image_cache)
5957 (lookup_image): Port to higer-resolution time stamps.
5959 * keyboard.c (start_polling, bind_polling_period):
5960 Check for time stamp overflow.

5963 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
5964 Port to higher-resolution time stamps. Do not assume time_t is signed.
5965 (decode_timer): New function. Timers are now vectors of length 9,
5966 not 8, to accommodate the picosecond component.
5967 (timer_check_2): Use it.
5969 * nsterm.m (select_timeout, timeval_subtract): Remove.
5970 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
5971 as they're a bit more accurate and handle overflow better.
5972 (ns_select): Change prototype to be compatible with pselect.
5973 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
5974 * nsterm.h (ns_select): Adjust prototype.
5976 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
5977 us-resolution time stamps.
5978 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
5980 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
5982 * lisp.h (time_overflow): New decl.
5983 (wait_reading_process_output): First arg is now intmax_t, not int,
5984 to accommodate larger waits.
5986 * process.h (struct Lisp_Process.read_output_delay):
5987 Now counts nanoseconds, not microseconds.
5988 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about

5994 Check for time stamp overflow. Do not assume time_t is signed.
5995 (select_wrapper): Remove; we now use pselect.
5996 (Fprocess_attributes): Now generates ns-resolution time stamps.
5998 * sysdep.c: Include utimens.h. Don't include utime.h
5999 or worry about struct utimbuf; gnulib does that for us now.
6000 (gettimeofday): Remove; gnulib provides a substitute.
6001 (make_timeval): New function.
6002 (set_file_times): Now sets ns-resolution time stamps.
6003 New arg FD; all uses changed.
6004 (time_from_jiffies, ltime_from_jiffies, get_up_time)
6005 (system_process_attributes):
6006 Now returns ns-resolution time stamp. All uses changed.
6007 Check for time stamp overflow.
6009 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
6010 provides a substitute now.
6012 * systime.h: Include timespec.h rather than sys/time.h and time.h,
6013 since it guarantees struct timespec.
6014 (EMACS_TIME): Now struct timespec, so that we can support
6015 ns-resolution time stamps.
6016 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
6017 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
6018 (EMACS_USECS): Remove.
6019 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
6020 so multiply the arg by 1000 before storing it.
6021 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
6023 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
6024 Port to ns-resolution time stamps.
6025 (EMACS_TIME_NEG_P): Remove; replaced by....

6030 (make_timeval, make_lisp_time, decode_time_components): New decls.
6031 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
6032 that it mishandled time_t overflow. You can't compare by subtracting!
6033 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
6034 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.

6045 (w32_get_internal_run_time):
6046 Port to higher-resolution Emacs time stamps.

6052 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
6053 for compatibility with pselect. Support ns-resolution time stamps.

6057 * xselect.c (wait_for_property_change, x_get_foreign_selection):
6058 Check for time stamp overflow, and support ns-resolution time stamps.
6060 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
6061 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
6062 (timeval_subtract): Remove; no longer needed.
6063 (XTflash, XTring_bell, x_wait_for_event):
6064 Port to ns-resolution time stamps. Don't assume time_t is signed.

6070 2012-06-22 Eli Zaretskii <eliz@gnu.org>
6072 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
6073 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
6074 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
6075 staticidx goes up to 1597 out of 1600 = 0x640.)
6077 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
6079 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
6080 Otherwise, the umask might be mistakenly 0 while handling input signals.

6125 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
6126 gets killed during executing of this function (Bug#11665).
6127 Try to always return Qt when the buffer has been actually killed.
6128 (Vkill_buffer_query_functions): In doc-string say that functions
6129 run by this hook should not change the current buffer.
6131 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
6133 Fix recently-introduced process.c problems found by static checking.

6154 This removes the need for CHECK.
6155 (CHECK): Remove. Its comments about always evaluating its
6156 argument were confusing, as 'eassert' typically does not evaluate
6159 * coding.c (produce_chars): Use ptrdiff_t, not int.
6161 * xterm.c (x_draw_underwave): Check for integer overflow.
6162 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

6336 * alloc.c (make_number) [!defined make_number]:
6337 Remove, as lisp.h always defines this now.
6338 (mark_maybe_pointer): Simplify since USE_LSB_TAG is always defined now.
6339 (roundup_size): Verify that it is a power of 2.
6340 * data.c (Fmake_variable_buffer_local, Fmake_local_variable):
6341 * ftfont.c (ftfont_driver): Use LISP_INITIALLY_ZERO.
6342 * lisp.h (USE_LSB_TAG): Allow the builder to compile with
6343 -DUSE_LSB_TAG=0, to override the automatically-selected default.
6344 USE_LSB_TAG now is always defined to be either 0 or 1.
6346 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
6347 code works fine either way, and efficiency is not a concern here,
6348 as the union type is for debugging, not for production.
6349 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
6350 Use an inline function on all platforms when using the union type,
6351 since this is simpler and 'static inline' can be used portably
6353 (LISP_INITIALLY_ZERO): New macro.
6354 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
6355 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.
6357 2012-06-12 Glenn Morris <rgm@gnu.org>

6372 MagickMergeImageLayers is undefined. Use pixel pusher loop if
6373 MagickExportImagePixels is undefined.

6381 * s/aix4-2.h, s/bsd-common.h, s/cygwin.h, s/darwin.h:
6382 * s/gnu-kfreebsd.h, s/gnu-linux.h, s/gnu.h, s/hpux10-20.h:
6383 * s/irix6-5.h, s/ms-w32.h, s/msdos.h, s/template.h:
6384 * s/usg5-4-common.h: Move SYSTEM_TYPE to configure.
6386 2012-06-11 Stefan Monnier <monnier@iro.umontreal.ca>
6388 * alloc.c (make_byte_code): New function.

6394 * image.c (imagemagick_load_image): Implement transparency.
6396 2012-06-10 Andreas Schwab <schwab@linux-m68k.org>

6423 * dbusbind.c (XD_BASIC_DBUS_TYPE): Use dbus_type_is_valid and
6424 dbus_type_is_basic if available.
6425 (xd_extract_signed, xd_extract_unsigned): Rename from
6426 extract_signed and extract_unsigned, respectively. Adapt callers.
6428 2012-06-09 Chong Yidong <cyd@gnu.org>
6430 * xfaces.c (face_for_overlay_string): Handle face remapping (Bug#2066).

6435 2012-06-08 Paul Eggert <eggert@cs.ucla.edu>
6437 * xdisp.c (vmessage): Treat frame message as multibyte.
6438 Without this change, (let ((§ 1)) (make-variable-buffer-local '§))
6439 would generate the diagnostic "Making \302\247 buffer-local while
6442 2012-06-08 Eli Zaretskii <eliz@gnu.org>
6444 * dispnew.c (showing_window_margins_p): Undo last change, which

6455 2012-06-08 Juanma Barranquero <lekktu@gmail.com>
6457 * dispnew.c (showing_window_margins_p): Wrap in #if 0 to prevent unused
6458 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
6460 2012-06-08 Eli Zaretskii <eliz@gnu.org>
6462 * alloc.c (allocate_vectorlike): Fix last change.
6464 2012-06-08 Dmitry Antipov <dmantipov@yandex.ru>
6466 Block-based vector allocation of small vectors.
6467 * lisp.h (struct vectorlike_header): New field `nbytes',
6468 adjust comment accordingly.
6469 * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'
6470 to denote vector blocks. Adjust users (live_vector_p,
6471 mark_maybe_pointer, valid_lisp_object_p) accordingly.
6472 (COMMON_MULTIPLE): Move outside #if USE_LSB_TAG.
6473 (VECTOR_BLOCK_SIZE, vroundup, VECTOR_BLOCK_BYTES),
6474 (VBLOCK_BYTES_MIN, VBLOCK_BYTES_MAX, VECTOR_MAX_FREE_LIST_INDEX),
6475 (VECTOR_FREE_LIST_FLAG, ADVANCE, VINDEX, SETUP_ON_FREE_LIST),
6476 (VECTOR_SIZE, VECTOR_IN_BLOCK): New macros.

6493 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
6495 * doprnt.c (doprnt): Truncate multibyte char correctly.
6496 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
6497 would mishandle a string argument "Xc" if X was a multibyte
6498 character of length 2: it would truncate after X's first byte
6499 rather than including all of X.
6501 2012-06-06 Chong Yidong <cyd@gnu.org>
6503 * buffer.c (word_wrap): Doc fix.

6552 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
6553 Convert pctcpu and pctmem to Lisp float properly.
6554 Let the compiler fold better, as 100.0/0x8000 is exact.
6556 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
6558 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
6561 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
6563 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
6565 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
6567 For a 'struct window', replace some Lisp_Object fields to
6568 bitfields where appropriate, remove unused fields.
6569 * window.h (struct window): Remove unused 'last_mark_x' and
6570 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
6571 change it's type from Lisp_Object to bitfield.
6572 Change type of 'force_start', 'optional_new_start',
6573 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
6574 fields from Lisp_Object to bitfield. Adjust users accordingly.
6576 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
6578 Pacify gcc -Wdouble-precision when using Xaw.
6579 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
6580 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
6581 Use 'float' consistently, rather than 'float' in most places
6582 and 'double' in a couple of places.
6584 2012-05-31 Eli Zaretskii <eliz@gnu.org>
6586 * xdisp.c (handle_stop): Detect whether we have overlay strings
6587 loaded by testing it->current.overlay_string_index to be
6588 non-negative, instead of checking whether n_overlay_strings is
6589 positive. (Bug#11587)
6591 2012-05-31 Chong Yidong <cyd@gnu.org>
6593 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
6595 * doc.c (Fsubstitute_command_keys): Doc fix.
6597 2012-05-31 Eli Zaretskii <eliz@gnu.org>
6599 * search.c (search_buffer): Remove calls to
6600 r_alloc_inhibit_buffer_relocation, as it is now called by
6601 maybe_unify_char, which was the cause of relocation of buffer text
6604 2012-05-31 Eli Zaretskii <eliz@gnu.org>
6606 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
6607 for the duration of call to load_charset, to avoid problems with
6608 callers of maybe_unify_char that access buffer text through C
6611 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
6612 decrement the inhibition flag, instead of just setting or
6615 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
6617 Remove obsolete '#define static' cruft.
6618 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
6619 This #undef was "temporary" in 2000; it is no longer needed
6620 now that '#define static' has gone away.
6621 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
6622 (gray_bitmap_bits): Remove; no longer needed.
6623 All uses replaced with definiens.
6624 * xterm.c: Include "bitmaps/gray.xbm".
6626 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
6628 Clean up __executable_start, monstartup when --enable-profiling.
6629 The following changes affect the code only when profiling.
6630 * dispnew.c (__executable_start): Rename from safe_bcopy.
6631 Define only on platforms that need it.
6632 * emacs.c: Include <sys/gmon.h> when profiling.
6633 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
6634 (__executable_start): Remove decl, since lisp.h does it now.
6635 (safe_bcopy): Remove decl; no longer has that name.
6636 (main): Coalesce #if into single bit of code, for simplicity.
6637 Cast pointers to uintptr_t, since standard libraries want integers

6662 * lread.c (read1): Tiny simplification.
6664 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
6666 Do not create empty overlays with the evaporate property (Bug#9642).
6667 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
6668 Bug#9642, but explicitly check that the buffer the overlay would
6669 be moved to is live and rearrange lines to make sure that errors
6670 will not put the overlay in an inconsistent state.
6671 (Fdelete_overlay): Cosmetics.
6673 2012-05-28 Eli Zaretskii <eliz@gnu.org>
6675 * w32term.c (my_bring_window_to_top): New function.
6676 (x_raise_frame): Use handle returned by DeferWindowPos, which
6677 could be different from the original one.

6687 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
6689 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
6690 This avoids undefined behavior that might cause the eassert
6691 to not catch an out-of-range value.
6693 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
6695 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

6707 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
6709 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
6710 Only r_alloc_inhibit_buffer_relocation needed to be added;
6711 the others were already declared.
6713 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
6714 before checking whether it's out of range. Put the check inside
6716 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
6718 2012-05-27 Ken Brown <kbrown@cornell.edu>
6720 * callproc.c (Fcall_process): Restore a line that was accidentally
6721 commented out in the 2011-02-13 change (bug#11547).

6725 * lisp.h [REL_ALLOC]: Add prototypes for external functions
6726 defined on ralloc.c.
6728 * buffer.c [REL_ALLOC]: Remove prototypes of
6729 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
6730 they are now on lisp.h.
6732 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
6734 * search.c (search_buffer): Use it to inhibit relocation of buffer
6735 text while re_search_2 is doing its job, because re_search_2 is
6736 passed C pointers to buffer text. (Bug#11519)
6738 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
6741 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
6742 state after an additional call to move_it_in_display_line_to, keep
6743 the values of it->max_ascent and it->max_descent found for the
6745 (pos_visible_p): Revert the comparison against bottom_y to what it
6746 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
6749 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
6751 Fix coding-related core dumps with gcc -ftrapv.
6752 The code was computing A - B, where A and B are pointers, and B is
6753 random garbage. This can lead to core dumps on platforms that
6754 have special pointer registers, and it also leads to core dumps on
6755 x86-64 when compiled with gcc -ftrapv. The fix is to compute
6756 A - B only when B is initialized properly.
6757 * coding.c (coding_set_source, coding_set_destination): Return void.
6758 (coding_change_source, coding_change_destinations): New functions,
6759 with the old behaviors of coding_set_source and coding_set_destination.
6760 All callers that need an offset changed to use these new functions.
6762 2012-05-26 Glenn Morris <rgm@gnu.org>
6764 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
6766 2012-05-26 Eli Zaretskii <eliz@gnu.org>
6768 Extend mouse support on W32 text-mode console.
6769 * xdisp.c (draw_row_with_mouse_face):
6770 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
6772 * w32console.c: Include window.h.
6773 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
6775 (initialize_w32_display): Initialize mouse-highlight data.
6777 * w32inevt.c: Include termchar.h and window.h.
6778 (do_mouse_event): Support mouse-autoselect-window. When the mouse
6779 moves, call note_mouse_highlight. If help_echo changed, call
6780 gen_help_event to produce help-echo message in the echo area.
6781 Call clear_mouse_face if mouse_face_hidden is set in the mouse
6784 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
6786 * lread.c (read1): Simplify slightly to avoid an overflow warning
6787 with GCC 4.7.0 on x86-64.
6789 2012-05-26 Eli Zaretskii <eliz@gnu.org>
6791 * bidi.c (bidi_mirror_char): Revert last change: an int is
6792 definitely wide enough here.
6794 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
6796 Fix integer width and related bugs (Bug#9874).
6797 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):

6801 (make_unibyte_string, make_multibyte_string)
6802 (make_string_from_bytes, make_specified_string)
6803 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
6804 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
6806 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6807 (allocate_pseudovector):
6808 Use int, not EMACS_INT, where int is wide enough.
6809 (inhibit_garbage_collection, Fgarbage_collect):

6828 (Foverlay_recenter, last_overlay_modification_hooks_used)
6829 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
6830 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6831 (validate_region): Omit unnecessary test for b <= e,
6832 since that's guaranteed by the previous test.
6833 (adjust_overlays_for_delete): Avoid pos + length overflow.
6834 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
6835 (report_overlay_modification):

6837 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):

6841 * buffer.h: Adjust decls to match defn changes elsewhere.

6846 not int, to avoid needless 32-bit limit on 64-bit hosts.
6847 (exec_byte_code): Use tighter memory-full test, one that checks
6848 for alloca overflow. Don't compute the address of the object just
6849 before an array, as that's not portable. Use EMACS_INT, not
6850 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
6851 * callint.c (Fcall_interactively):
6852 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

6865 (casify_object): Avoid integer overflow when overallocating buffer.
6866 * casetab.c (set_identity, shuffle): Prefer int to unsigned when

6869 * category.h (CATEGORYP): Don't assume arg is nonnegative.
6870 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the

6873 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6874 For CCL_MapSingle, check that content and value are in int range.

6876 Check that Vcode_version_map_vector is a vector.
6877 (resolve_symbol_ccl_program): Check that vector header is in range.
6878 Always copy the vector, so that we can check its contents reliably
6879 now rather than having to recheck each instruction as it's being
6880 executed. Check that vector words fit in 'int'.
6881 (ccl_get_compiled_code, Fregister_ccl_program)
6882 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
6883 program indexes, to avoid needless 32-bit limit on 64-bit hosts.

6885 contents are in range.
6886 (Fccl_execute_on_string): Check that status is in range.
6887 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
6888 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
6889 Accept and return EMACS_INT, not int, because callers can pass values

6896 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

6898 avoid mishandling large integers.

6910 Don't assume unsigned int fits into fixnum, or that fixnum fits
6911 into unsigned int. Don't require max_code to be a valid fixnum;
6912 that's not true for gb10830 4-byte on a 32-bit host. Allow
6913 invalid_code to be a cons, for the same reason. Require code_offset
6914 to be a character. Avoid int overflow if max_char is close
6916 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
6917 this is intended anyway and avoids some undefined behavior.
6918 (load_charset_map): Pass unsigned, not int, as 2nd arg of
6919 INDEX_TO_CODE_POINT, as that's what it expects.
6920 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
6921 * charset.h (DECODE_CHAR): Return int, not unsigned;
6922 this is what was intended anyway, and it avoids undefined behavior.
6923 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
6924 integer-overflow issues.
6925 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
6926 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
6927 where the argument is EMACS_INT, and this behavior is not intended.
6928 * chartab.c (Fmake_char_table, Fset_char_table_range)
6929 (uniprop_get_decoder, uniprop_get_encoder):
6930 Don't assume fixnum fits in int.
6931 * cmds.c (move_point): New function, that does the gist of
6932 Fforward_char and Fbackward_char, but does so while checking
6933 for integer overflow more accurately.
6934 (Fforward_char, Fbackward_char): Use it.
6935 (Fforward_line, Fend_of_line, internal_self_insert)
6936 (internal_self_insert):
6937 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

7593 rather than rolling our own approximation.
7594 (SCROLL_BAR_VEC_SIZE): Remove; not used.
7596 2012-05-25 Glenn Morris <rgm@gnu.org>
7598 * lisp.mk (lisp): Update for more files being compiled now.
7600 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>
7602 * lread.c: Remove `read_pure' which makes no difference.
7603 (read_pure): Remove var.
7604 (unreadpure): Remove function.
7605 (readevalloop): Don't call read_list with -1 flag.

7620 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
7623 This directory predates autoconf and is no longer needed nowadays.
7624 Move its few remaining bits of functionality to where they're needed.
7625 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:

7634 (EMACS_UINT): Define unconditionally now.
7635 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
7636 (BITS_PER_EMACS_INT): New constants, replacing
7637 what used to be in config.h, but not useful in #if.
7638 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
7639 define them any more.
7640 (VAL_MAX): New macro.
7642 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
7643 BITS_PER_EMACS_INT, in #if.
7644 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
7645 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
7646 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
7647 * s/ms-w32.h (DATA_START):
7648 Move here from removed file m/intel386.h.
7649 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
7650 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
7652 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
7654 Assume C89 or later.

7663 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
7664 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
7665 * xterm.c (input_signal_count): Assume volatile works.
7667 2012-05-21 Ken Brown <kbrown@cornell.edu>
7669 * xgselect.c (xg_select): Fix first argument in call to 'select'
7672 2012-05-20 Ken Brown <kbrown@cornell.edu>
7674 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
7675 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
7677 2012-05-19 Ken Brown <kbrown@cornell.edu>
7679 * xfns.c (x_in_use): Remove `static' qualifier.
7680 * xterm.h (x_in_use): Declare.
7681 * xgselect.c: Include xterm.h.
7682 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
7683 and `display_arg' (bug#9754).
7685 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
7687 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
7689 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
7690 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
7692 2012-05-18 Eli Zaretskii <eliz@gnu.org>
7694 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
7696 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
7697 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
7699 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
7700 reference to image_cache->refcount.
7701 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
7703 2012-05-17 Juri Linkov <juri@jurta.org>
7705 * search.c (Fword_search_regexp, Fword_search_backward)
7706 (Fword_search_forward, Fword_search_backward_lax)
7707 (Fword_search_forward_lax): Move functions to isearch.el
7708 (bug#10145, bug#11381).
7710 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
7712 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
7714 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
7716 * lread.c (init_obarray): Declare Qt and Qnil as special.
7718 2012-05-14 Glenn Morris <rgm@gnu.org>
7720 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
7721 Put "libexec" before "bin", for the sake of init_callproc_1.
7723 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
7725 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
7727 * unexaix.c: Port to more-recent AIX compilers.
7728 (report_error, report_error_1, make_hdr, copy_sym)
7729 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
7730 Make arguments const char *, not char *, to avoid violations of C
7731 standard and to fix some AIX warnings reported by Gilles Pion.
7733 2012-05-14 Eli Zaretskii <eliz@gnu.org>
7735 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
7736 already have overlays loaded.
7737 (handle_single_display_spec): Before returning without displaying
7738 fringe bitmap, synchronize the bidi iterator with the main display
7739 iterator, by calling iterate_out_of_display_property.
7740 (iterate_out_of_display_property): Detect buffer iteration by
7741 testing that it->string is a Lisp string.
7742 (get_next_display_element): When the current object is exhausted,
7743 and there's something on it->stack, call set_iterator_to_next to
7744 proceed with what's on the stack, instead of returning zero.
7745 (set_iterator_to_next): If called at the end of a Lisp string,
7746 proceed to consider_string_end without incrementing string
7747 position. Don't increment display vector index past the end of
7748 the display vector. (Bug#11417)
7749 (pos_visible_p): Don't report a position visible when move_it_to
7750 stopped at the last line of window, which happens to be scanned
7751 backwards by the bidi iteration. (Bug#11464)
7753 2012-05-14 Eli Zaretskii <eliz@gnu.org>
7755 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
7756 and right-margin display specs even if the spec is invalid or we
7757 are on a TTY, and thus unable to display on the fringes.
7758 That's because the text with the property will not be displayed anyway,
7759 so we need to signal to the caller that this is a "replacing"
7760 display spec. This fixes display when the spec is invalid or we
7763 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
7765 * unexaix.c (make_hdr): Fix typo in prototype.
7766 This bug broke the build on AIX. Problem reported by Gilles Pion.
7768 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
7770 * keyboard.c (kbd_buffer_get_event): Read special events also in
7771 batch mode. (Bug#11415)
7773 2012-05-12 Glenn Morris <rgm@gnu.org>
7775 * ns.mk: Update for ns_appbindir no longer having trailing "/".
7777 2012-05-12 Eli Zaretskii <eliz@gnu.org>
7779 * lisp.mk (lisp): Add newcomment.elc.
7781 2012-05-12 Glenn Morris <rgm@gnu.org>
7783 * Makefile.in (MKDIR_P): New, set by configure.
7784 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
7786 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
7788 Remove unused function hourglass_started.
7789 * dispextern.h (hourglass_started):
7790 * w32fns.c (hourglass_started):
7791 * xdisp.c (hourglass_started): Remove.
7793 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
7795 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
7796 Update dependencies.
7798 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
7800 * xgselect.c (xg_select): Put maxfds+1 into a var.
7801 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
7803 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
7805 2012-05-10 Dave Abrahams <dave@boostpro.com>
7807 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
7808 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
7810 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
7812 * dbusbind.c (xd_registered_buses): New internal Lisp object.
7813 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
7814 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
7815 Initialize xd_registered_buses.
7817 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
7819 Untag more efficiently if USE_LSB_TAG.
7820 This is based on a proposal by YAMAMOTO Mitsuharu in
7821 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
7822 For an admittedly artificial (nth 8000 longlist) benchmark on
7823 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
7824 Emacs's overall text size by 1%.
7825 * lisp.h (XUNTAG): New macro.
7826 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
7827 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
7828 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
7829 * eval.c (Fautoload):
7830 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
7831 * frame.h (XFRAME): Use XUNTAG.
7833 Port recent dbusbind.c changes to 32-bit --with-wide-int.
7834 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
7835 Remove unportable assumptions about print widths of types like
7837 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
7838 intptr_t when converting between pointer and integer, to avoid GCC
7839 warnings about wrong width.
7841 2012-05-09 Eli Zaretskii <eliz@gnu.org>
7843 * w32proc.c (new_child): Force Windows to reserve only 64KB of
7844 stack for each reader_thread, instead of defaulting to 8MB
7845 determined by the linker. This avoids failures in creating
7846 subprocesses on Windows 7, see the discussion in this thread:
7847 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
7849 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
7851 Fix up display of the *Minibuf-0* buffer in the mini window.
7852 * keyboard.c (read_char): Don't clear the echo area if there's no
7854 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
7855 contents of *Minibuf-0*) if there's no message displayed in its stead.
7857 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
7859 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
7862 2012-05-06 Chong Yidong <cyd@gnu.org>
7864 * lisp.mk (lisp): Update.
7866 2012-05-05 Jim Meyering <meyering@redhat.com>
7868 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
7870 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
7872 * data.c (PUT_ERROR): New macro.
7873 (syms_of_data): Use it. Add new error type `user-error'.
7874 * undo.c (user_error): New function.
7875 (Fprimitive_undo): Use it.
7876 * print.c (print_error_message): Adjust print style for `user-error'.
7877 * keyboard.c (user_error): New function.
7878 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
7880 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
7882 Do not limit current-time-string to years 1000..9999.
7883 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
7884 (Fcurrent_time_string): Support any year that is supported by the
7885 underlying localtime representation. Don't use asctime, as it
7886 has undefined behavior for years outside the range -999..9999.
7888 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
7890 Fix race conditions involving setenv, gmtime, localtime, asctime.
7891 Without this fix, interrupts could mess up code that uses these
7892 nonreentrant functions, since setting TZ invalidates existing
7893 tm_zone or tzname values, and since most of these functions return
7894 pointers to static storage.
7895 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
7896 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
7897 Grow the critical sections to include not just invoking
7898 localtime/gmtime, but also accessing these functions' results
7899 including their tm_zone values if any, and any related TZ setting.
7900 (format_time_string): Last arg is now struct tm *, not struct tm **,
7901 so that the struct tm is saved in the critical section.
7902 All callers changed. Simplify allocation of initial buffer, partly
7903 motivated by the fact that memory allocation needs to be outside
7904 the critical section.
7906 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
7908 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
7909 with RESET_INTERVAL.
7911 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
7912 Remove duplicated buffer name initialization.
7914 2012-05-02 Jim Meyering <jim@meyering.net>
7916 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
7918 * xfns.c (x_window): Use xstrdup (Bug#11375).
7920 2012-05-02 Eli Zaretskii <eliz@gnu.org>
7922 * xdisp.c (pos_visible_p): If already at a newline from the
7923 display string before the 'while' loop, don't walk back the glyphs
7924 from it3.glyph_row. Solves assertion violation when the display
7925 string begins with a newline (egg.el). (Bug#11367)
7927 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
7929 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
7932 2012-05-01 Glenn Morris <rgm@gnu.org>
7934 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
7935 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
7936 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
7937 All were removed before 23.1.
7939 * dispnew.c: Remove HAVE_LIBNCURSES test;
7940 it is always true on relevant platforms.
7942 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
7943 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
7945 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.

7955 Do not avoid creating empty evaporating overlays (Bug#9642).
7956 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
7957 That is, do not delete an evaporating overlay if it becomes
7958 empty after its bounds are adjusted to fit within its buffer.
7959 This fix caused other problems, and I'm reverting it until we get
7960 to the bottom of them.
7962 2012-04-27 Chong Yidong <cyd@gnu.org>
7964 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
7966 2012-04-27 Eli Zaretskii <eliz@gnu.org>
7968 * xdisp.c (pos_visible_p): If the window start position is beyond
7969 ZV, start the display from buffer beginning. Prevents assertion
7970 violation in init_iterator when the minibuffer window is scrolled
7973 * window.c (window_scroll_pixel_based): Likewise.
7975 2012-04-27 Chong Yidong <cyd@gnu.org>

7991 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
7992 display element, check also the underlying string or buffer
7993 character. (Bug#11341)
7995 * w32menu.c: Include w32heap.h.
7996 (add_menu_item): If the call to AppendMenuW (via
7997 unicode_append_menu) fails, disable Unicode menus only if we are
7998 running on Windows 9X/Me.
8000 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
8002 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.

8005 2012-04-24 Martin Rudalics <rudalics@gmx.at>
8007 * keyboard.c (read_char): Don't wipe echo area for select window

8013 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
8014 manipulation of :loaded-from data.
8016 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
8018 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
8019 now a cons (bug#11311).
8021 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
8023 Do not create empty overlays with the evaporate property (Bug#9642).
8024 * buffer.c (Fmove_overlay): Delete an evaporating overlay
8025 if it becomes empty after its bounds are adjusted to fit within
8026 its buffer. Without this fix, in a nonempty buffer (let ((o
8027 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
8028 yields an empty overlay that has the evaporate property, which is
8029 not supposed to happen.
8031 Fix minor GTK3 problems found by static checking.
8032 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)

8146 * sysdep.c [__FreeBSD__]: Minor cleanups.
8147 (list_system_processes, system_process_attributes) [__FreeBSD__]:
8148 Use Emacs indenting style more consistently. Avoid some casts.
8149 Use 'double' consistently rather than mixing 'float' and 'double'.

8169 (print_object): Check for cycles even when print-circle is nil and
8170 print-gensym is t, but only check print_depth if print-circle is nil.
8172 2012-04-20 Chong Yidong <cyd@gnu.org>
8174 * process.c (wait_reading_process_output): If EIO occurs on a pty,
8175 set the status to "failed" and ensure that sentinel is run.

8230 New extern decls, to avoid calling undeclared functions.
8231 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
8232 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
8233 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
8234 (NEED_MEM_INSERT): New macro.
8235 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
8236 Remove one incorrect comment and fix another.

8249 [REL_ALLOC]: ... to here, to check interface.
8250 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
8251 Remove decls. This fixes an "It stinks!".
8253 * alloc.c (which_symbols): Fix alignment issue / type clash.
8255 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
8257 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

8277 no longer the default.
8278 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
8280 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
8282 * lread.c (lisp_file_lexically_bound_p):

8303 2012-04-11 Daniel Colascione <dancol@dancol.org>
8305 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
8306 against is gone. It's better to use vfork now so that when Cygwin
8307 gains a new, working vfork, we use it automatically (bug#10398).
8309 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
8311 * window.c (save_window_save): Obey window-point-insertion-type.

8330 being loaded (bug#10424).
8332 2012-04-09 Glenn Morris <rgm@gnu.org>
8334 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
8335 not just in the obarray, before snarfing them. (Bug#11036)

8347 Add convenience `GNUTLS_LOG2i' macro.
8349 * gnutls.c (gnutls_log_function2i): Convenience log function.
8350 (emacs_gnutls_read): Use new log functions,
8351 `gnutls_handshakes_tried' process member, and
8352 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
8353 attempts per process (connection).
8355 2012-04-09 Chong Yidong <cyd@gnu.org>

8362 * minibuf.c (Fread_variable): Callers changed.
8364 2012-04-09 Eli Zaretskii <eliz@gnu.org>
8366 * xdisp.c (set_cursor_from_row): If the display string appears in
8367 the buffer at position that is closer to point than the position
8368 after the display string, display the cursor on the first glyph of
8369 the display string. Fixes cursor display when a 'display' text
8370 property immediately follows invisible text. (Bug#11094)
8372 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
8374 composite.c: use 'double' consistently
8375 * composite.c (get_composition_id): Use 'double' consistently
8376 instead of converting 'float' to 'double' and vice versa; this is
8377 easier to understand and avoids a GCC warning.
8379 2012-04-09 Glenn Morris <rgm@gnu.org>
8381 * Makefile.in: Generate leim-list with bootstrap-emacs, in
8382 preparation for dumping it with emacs. (Bug#4789)

8403 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
8404 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
8405 (mark_memory): Mark Lisp_Objects only if pointers might hide in
8406 objects, as mark_maybe_pointer will catch them otherwise.
8407 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
8408 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
8410 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
8412 Fix typo that broke non-Windows builds.
8413 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.

8426 [!WINDOWSNT]: New macros.
8427 (init_libxml2_functions, libxml2_loaded_p): New functions.
8428 (parse_region): Call fn_xmlCheckVersion instead of using the macro
8429 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
8430 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
8431 Calls xmlCleanupParser only if libxml2 was loaded (or statically
8433 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
8434 Call init_libxml2_functions before calling libxml2 functions.
8435 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
8437 * emacs.c: Don't include libxml/parser.h.
8438 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
8439 xmlCleanupParser directly.
8441 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
8443 2012-04-07 Eli Zaretskii <eliz@gnu.org>
8445 * indent.c (Fvertical_motion): If there is a display string at
8446 point, use it.vpos to compute how many lines to backtrack after

8451 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
8452 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
8453 about subtle differences between FETCH_CHAR* and STRING_CHAR*
8454 macros related to unification of CJK characters. For the details,
8455 see the discussion following the message here:
8456 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
8458 2012-04-04 Chong Yidong <cyd@gnu.org>
8460 * keyboard.c (Vdelayed_warnings_list): Doc fix.
8462 2012-04-01 Eli Zaretskii <eliz@gnu.org>
8464 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA

8467 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
8469 * w32menu.c (is_simple_dialog): Properly check lisp types.
8472 2012-03-31 Eli Zaretskii <eliz@gnu.org>
8474 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
8475 position we get to after a call to move_it_to fails the
8476 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
8477 only if we wind up in a string from display property. (Bug#11063)
8479 * window.c (Fdelete_other_windows_internal): Invalidate the row
8480 and column information about mouse highlight, so that redisplay
8481 restores it after reallocating the glyph matrices. (Bug#7464)
8483 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
8484 string comes from a `display' text property, use the buffer
8485 position of that property as if we actually saw that position in
8487 (move_it_by_lines): Remove the assertion that
8488 "it->current_x == 0 && it->hpos == 0" which can be legitimately
8489 violated when there's a before-string at the beginning of a line.
8492 2012-03-30 Eli Zaretskii <eliz@gnu.org>
8494 * xdisp.c (append_space_for_newline): If the default face was
8495 remapped, use the remapped face for the appended newline.
8496 (extend_face_to_end_of_line): Use the remapped default face for
8497 extending the face to the end of the line.
8498 (display_line): Call extend_face_to_end_of_line when the default
8499 face was remapped. (Bug#11068)
8501 2012-03-29 Eli Zaretskii <eliz@gnu.org>
8503 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
8505 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
8507 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
8509 2012-03-27 Glenn Morris <rgm@gnu.org>

8514 2012-03-26 Kenichi Handa <handa@m17n.org>
8516 * dispextern.h (struct glyph): Fix previous change. Change the
8517 bit length of glyphless.ch to 25 (Bug#11082).
8519 2012-03-26 Chong Yidong <cyd@gnu.org>
8521 * keyboard.c (Vselection_inhibit_update_commands): New variable.
8522 (command_loop_1): Use it; inhibit selection update for
8523 handle-select-window too (Bug#8996).
8525 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
8527 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
8529 2012-03-25 Kenichi Handa <handa@m17n.org>
8531 * dispextern.h (struct glyph): Change the bit length of
8532 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
8534 2012-03-24 Eli Zaretskii <eliz@gnu.org>
8536 * s/ms-w32.h (tzname): Include time.h before redirecting to
8537 _tzname. Fixes the MSVC build. (Bug#9960)
8539 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
8541 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
8544 * xterm.c (XTread_socket): Only modify handling_signal if
8545 !SYNC_INPUT. (Bug#11080)
8547 2012-03-23 Eli Zaretskii <eliz@gnu.org>
8549 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
8550 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
8551 when fetching a multibyte character consumes more bytes than
8552 CHAR_BYTES returns, due to unification of CJK characters in
8553 string_char. (Bug#11073)
8555 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
8557 * process.c (wait_reading_process_output): Handle pty disconnect
8558 by refraining from sending oneself a SIGCHLD (bug#10933).
8560 2012-03-22 Chong Yidong <cyd@gnu.org>
8562 * dispextern.h (struct it): New member string_from_prefix_prop_p.

8573 2012-03-20 Eli Zaretskii <eliz@gnu.org>
8575 * w32proc.c (Fw32_set_console_codepage)
8576 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):

8581 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
8582 to reflect default non-nil value of redisplay-dont-pause.
8584 2012-03-19 Kenichi Handa <handa@m17n.org>

8587 it fit in a valid range (Bug#11003).
8589 2012-03-18 Eli Zaretskii <eliz@gnu.org>
8591 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
8592 that is not from display property, accept the row as a "cursor
8593 row" if one of the string's character has a non-nil `cursor'
8594 property. Fixes cursor positioning when there are newlines in
8595 overlay strings, e.g. in icomplete.el. (Bug#11035)
8597 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
8599 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
8601 2012-03-12 Chong Yidong <cyd@gnu.org>
8603 * eval.c (inhibit_lisp_code): Rename from
8604 inhibit_window_configuration_change_hook; move from window.c.
8606 * xfns.c (unwind_create_frame_1, Fx_create_frame):
8607 * window.c (run_window_configuration_change_hook)
8608 (syms_of_window): Callers changed.
8610 2012-03-11 Chong Yidong <cyd@gnu.org>

8623 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
8625 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
8627 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
8628 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
8631 2012-03-03 Glenn Morris <rgm@gnu.org>
8633 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
8635 2012-03-02 Eli Zaretskii <eliz@gnu.org>
8637 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
8638 position past the first glyph_row that ends at ZV. (Bug#10902)
8639 (redisplay_window, next_element_from_string): Fix typos in
8641 (redisplay_window): Pass to move_it_vertically the margin in
8642 pixels, not in screen lines.
8644 2012-03-02 Glenn Morris <rgm@gnu.org>
8646 * buffer.c (buffer-list-update-hook): Doc fix.
8648 2012-02-29 Eli Zaretskii <eliz@gnu.org>
8650 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
8651 push_it before setting up the iterator for the first overlay
8652 string, even if we have an empty string loaded.
8653 (next_overlay_string): If there's an empty string on the iterator
8654 stack, pop the stack. (Bug#10903)
8656 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
8658 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
8659 Suggested by Stefan Monnier in
8660 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
8661 * alloc.c (widen_to_Lisp_Object): New static function.
8662 (mark_memory): Also mark Lisp_Objects by fetching pointer words
8663 and widening them to Lisp_Objects. This would work even if
8664 USE_LSB_TAG is defined and wide integers are used, which might
8665 happen in a future version of Emacs.
8667 2012-02-25 Chong Yidong <cyd@gnu.org>
8669 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
8672 * xselect.c (Fx_selection_exists_p): Doc fix.
8673 (x_clipboard_manager_save_all): Print an informative message
8674 before saving to clipboard manager.
8676 2012-02-24 Chong Yidong <cyd@gnu.org>
8678 * keyboard.c (process_special_events): Handle all X selection
8679 requests in kbd_buffer, not just the next one (Bug#8869).
8681 2012-02-23 Chong Yidong <cyd@gnu.org>
8683 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
8684 call when setting menu-bar-lines and tool-bar-lines parameters.
8685 (unwind_create_frame_1): New helper function.
8687 * window.c (inhibit_window_configuration_change_hook): New var.
8688 (run_window_configuration_change_hook): Obey it.
8689 (syms_of_window): Initialize it.
8691 2012-02-22 Chong Yidong <cyd@gnu.org>
8693 * xterm.c (x_draw_image_relief): Add missing type check for
8694 Vtool_bar_button_margin (Bug#10743).

8698 * fileio.c (Vfile_name_handler_alist): Doc fix.
8700 * buffer.c (Fget_file_buffer): Protect against invalid file
8701 handler return value.
8703 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
8705 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
8706 when computing $valmask.
8708 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
8709 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
8710 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
8711 It's useless in that case, and it can cause problems on hosts
8712 that allocate halves of EMACS_INT values separately.
8713 Reported by Dan Horák. Diagnosed by Andreas Schwab in
8714 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
8715 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
8716 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
8717 it avoids undefined behavior on hosts where shifting right by more
8718 than the word width has undefined behavior.
8720 2012-02-19 Chong Yidong <cyd@gnu.org>
8722 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
8723 (Funhandled_file_name_directory, Ffile_name_as_directory)
8724 (Fdirectory_file_name, Fexpand_file_name)
8725 (Fsubstitute_in_file_name): Protect against invalid file handler
8726 return values (Bug#10845).
8728 2012-02-18 Eli Zaretskii <eliz@gnu.org>
8730 * .gdbinit (pitx): Fix incorrect references to fields of the
8733 2012-02-17 Chong Yidong <cyd@gnu.org>

8740 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
8742 2012-02-15 Chong Yidong <cyd@gnu.org>
8744 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
8745 marked as special. Also, starting docstrings with * is obsolete.
8747 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>

8760 2012-02-12 Chong Yidong <cyd@gnu.org>
8762 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
8763 as that creates a dangerous corner case.
8765 * window.c (Fdelete_window_internal): Invalidate the mouse
8766 highlight (Bug#9904).
8768 2012-02-12 Glenn Morris <rgm@gnu.org>
8770 * xselect.c (Fx_own_selection_internal)
8771 (Fx_get_selection_internal, Fx_disown_selection_internal)
8772 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
8773 * nsselect.m (Fx_own_selection_internal)
8774 (Fx_disown_selection_internal, Fx_selection_exists_p)
8775 (Fx_selection_owner_p, Fx_get_selection_internal):
8776 Sync docs and argument specs with the xselect.c versions.
8778 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
8780 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
8782 2012-02-11 Eli Zaretskii <eliz@gnu.org>

8798 2012-02-07 Chong Yidong <cyd@gnu.org>
8800 * buffer.c (Fbuffer_local_variables)
8801 (buffer_lisp_local_variables): Handle unbound vars correctly;
8802 don't let Qunbound leak into Lisp.
8804 2012-02-07 Glenn Morris <rgm@gnu.org>
8806 * image.c (Fimagemagick_types): Doc fix.
8808 * image.c (imagemagick-render-type): Change it from a lisp object
8809 to an integer. Move the doc here from the lisp manual.

8812 2012-02-06 Chong Yidong <cyd@gnu.org>
8814 * doc.c (store_function_docstring): Avoid applying docstring of
8815 alias to base function (Bug#2603).
8817 2012-02-04 Andreas Schwab <schwab@linux-m68k.org>
8819 * .gdbinit (pp1, pv1): Remove redundant defines.
8822 2012-02-04 Chong Yidong <cyd@gnu.org>
8824 * nsterm.m: Declare a global (Bug#10694).
8826 2012-02-04 Eli Zaretskii <eliz@gnu.org>
8828 * w32.c (get_emacs_configuration_options):
8829 Include --enable-checking, if specified, in the return value.
8831 2012-02-04 Martin Rudalics <rudalics@gmx.at>
8833 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
8834 after rounding frame sizes. (Bug#9723)

8838 * keyboard.c (adjust_point_for_property): Don't position point
8839 before BEGV. (Bug#10696)
8841 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
8843 Handle overflow when computing char display width (Bug#9496).
8844 * character.c (char_width): Return EMACS_INT, not int.
8845 (char_width, c_string_width): Check for overflow when
8846 computing the width; this is possible now that individual
8847 characters can have unbounded width. Problem introduced
8848 by merge from Emacs 23 on 2012-01-19.
8850 2012-02-02 Michael Albinus <michael.albinus@gmx.de>
8852 * dbusbind.c (Fdbus_register_method): Mention the return value

8865 2012-02-02 Kenichi Handa <handa@m17n.org>
8867 (x_produce_glyphs): Cancel previous change. If cmp->glyph_len is
8868 0, do not call append_composite_glyph.
8870 2012-02-02 Kenichi Handa <handa@m17n.org>
8872 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
8874 (x_produce_glyphs): If the component of a composition is a null
8875 string, set it->pixel_width to 1 to avoid zero-width glyph.
8877 2012-02-01 Eli Zaretskii <eliz@gnu.org>
8879 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
8880 first 2 arguments are identical. This makes inserting large
8881 output from a subprocess an order of magnitude faster on
8882 MS-Windows, where all sbrk'ed memory is always contiguous.

9412 * xdisp.c (redisplay_window): If cursor row is not fully visible
9413 after recentering, and scroll-conservatively is set to a large
9414 number, scroll window by a few more lines to make the cursor fully
9415 visible and out of scroll-margin. (Bug#10105)

9501 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
9502 is set, removing the need for VIRT_ADDRESS_VARIES.
9503 (PURE_P): Use a more-efficient implementation that needs just one
9504 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
9505 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
9506 to 4 (xorl, subq, cmpq, setbe).
9507 * alloc.c (pure): Always extern now, since that's the
9508 VIRT_ADDR_VARIES behavior.
9509 (PURE_POINTER_P): Use a single comparison, not two, for
9510 consistency with the new puresize.h.
9511 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.

9518 (erase_phys_cursor, update_window_cursor, show_mouse_face)
9519 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
9520 behave as if the cursor position were at the window margin.
9522 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
9523 and the cursor position is out of bounds, behave as if the cursor
9524 position were at the window margin. (Bug#10075)
9526 2011-11-18 Chong Yidong <cyd@gnu.org>
9528 * window.c (Fwindow_combination_limit): Make first argument

9550 compute_line_metrics.
9551 (compute_line_metrics): Call row_hash, instead of computing the
9554 * dispnew.c (verify_row_hash): Call row_hash for computing the
9555 hash code of a row, instead of duplicating code from xdisp.c.
9557 * dispextern.h (row_hash): Add prototype.
9559 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>

9585 (Vwindow_nest): Rename to Vwindow_combination_limit.
9586 (recombine_windows, make_parent_window, make_window)
9587 (Fsplit_window_internal, saved_window)
9588 (Fset_window_configuration, save_window_save): Rename all
9589 occurrences of window_nest to window_combination_limit.
9591 2011-11-15 Juanma Barranquero <lekktu@gmail.com>
9593 * image.c (imagemagick_load_image): Fix typo.
9595 2011-11-14 Eli Zaretskii <eliz@gnu.org>
9597 * xdisp.c (display_line): Move the call to
9598 highlight_trailing_whitespace before the call to
9599 compute_line_metrics, since the latter needs to see the final
9600 faces of all the glyphs to compute ROW's hash value.
9601 Fixes assertion violations in row_equal_p. (Bug#10035)
9603 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
9605 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,

9610 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
9611 with user-defined heap size. Bump the default size of the temacs
9612 heap to 27MB, to avoid memory warning when running temacs.
9613 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
9615 * dispnew.c (scrolling_window): Fix incorrect indices in accessing

9662 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
9664 Avoid some portability problems by eschewing 'extern inline' functions.
9665 The trivial performance wins aren't worth the portability hassles; see
9666 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
9668 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

9670 (window_box_right, window_box_right_offset): Undo previous change,
9671 by removing the "extern"s.
9672 * intervals.c (adjust_intervals_for_insertion)
9673 (adjust_intervals_for_deletion): Undo previous change,
9674 making these static again.
9675 (offset_intervals, temp_set_point_both, temp_set_point)
9676 (copy_intervals_to_string): No longer inline.
9677 * xdisp.c (window_text_bottom_y, window_box_width)

9742 (window_box_width, window_box_left, window_box_left_offset)
9743 (window_box_right, window_box_right_offset): Declare extern.
9744 Otherwise, these inline functions do not conform to C99 and
9745 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
9746 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
9747 * intervals.c (adjust_intervals_for_insertion)
9748 (adjust_intervals_for_deletion): Now extern, because otherwise the
9749 extern inline functions 'offset_intervals' couldn't refer to it.
9750 (static_offset_intervals): Remove.
9751 (offset_intervals): Rewrite using the old contents of
9752 static_offset_intervals. The old version didn't conform to C99
9753 because an extern inline function contained a reference to an
9754 identifier with static linkage.

9776 (Fwindow_vscroll): Doc fix.
9777 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
9778 argument, since it makes no sense to pass a live window and for
9779 consistency with window-child.

9806 * nsfns.m: Declare image_cache_refcount if GLYPH_DEBUG.
9807 (unwind_create_frame): New function (Bug#9943).
9808 (Fx_create_frame): Restructure code to be more similar to the one in
9809 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).
9810 Initialize image_cache_refcount if GLYPH_DEBUG (Bug#9943).
9811 Move terminal->reference_count++ just before making the frame official
9814 * nsterm.m (x_free_frame_resources): New function.
9815 (x_destroy_window): Move code to x_free_frame_resources.
9817 * xfns.c (unwind_create_frame): Fix comment.

9819 Move terminal->reference_count++ just before making the frame
9820 official. Move initialization of image_cache_refcount and
9821 dpyinfo_refcount before calling init_frame_faces (Bug#9943).

9856 * regex.c <re_char> [_MSC_VER]: A separate definition for MSVC.
9858 2011-11-04 Eli Zaretskii <eliz@gnu.org>
9860 * xdisp.c (note_mouse_highlight): If either of
9861 previous/next-single-property-change returns nil, treat that as
9862 the beginning or the end of the buffer. (Bug#9955)
9864 2011-11-04 Jan Djärv <jan.h.d@swipnet.se>
9866 * gtkutil.c (xg_make_tool_item): Add callbacks if one of wimage or
9867 label is not null (Bug#9951).
9868 (xg_tool_item_stale_p): Handle the fact that wimage and/or wlbl
9871 2011-11-04 Eli Zaretskii <eliz@gnu.org>
9873 * window.c (Fwindow_body_size): Mention in the doc string that the
9874 return value is in frame's canonical units. (Bug#9949)
9876 2011-11-03 Eli Zaretskii <eliz@gnu.org>
9878 * xdisp.c (note_mouse_highlight): Initialize `area'. (Bug#9947)
9880 * w32fns.c (unwind_create_frame): If needed, free the glyph
9881 matrices of the partially constructed frame. (Bug#9943)
9882 * xfns.c (unwind_create_frame): Likewise.
9884 2011-11-01 Eli Zaretskii <eliz@gnu.org>
9886 * xdisp.c (mouse_face_from_buffer_pos): Fix a typo in a comment.
9887 Don't stop backward scan on the continuation glyph, even though
9888 its CHARPOS is positive.
9889 (mouse_face_from_buffer_pos, note_mouse_highlight):
9890 Rename cover_string to disp_string.
9892 2011-11-01 Martin Rudalics <rudalics@gmx.at>
9894 * window.c (temp_output_buffer_show): Don't use
9895 Vtemp_buffer_show_specifiers.
9896 (Vtemp_buffer_show_specifiers): Remove unused variable.
9898 2011-10-30 Eli Zaretskii <eliz@gnu.org>
9900 * xdisp.c (try_cursor_movement): Make sure ROW isn't decremented
9901 past the beginning of the current glyph matrix.
9903 2011-10-30 Adam Sjøgren <asjo@koldfront.dk> (tiny change)
9905 * xterm.c: Include X11/Xproto.h if HAVE_GTK3.
9906 (x_error_handler): Ignore BadMatch for X_SetInputFocus for
9907 HAVE_GTK3 (Bug#9869).
9909 * gtkutil.c (xg_win_to_widget, xg_event_is_for_menubar): Initialize
9910 type to GDK_NOTHING so valgrind does not complain (Bug#9901).
9912 * xterm.h (x_display_info): Add Xatom_net_wm_state_hidden (Bug#9893).
9914 * xterm.c: Declare x_handle_net_wm_state to return int.
9915 (handle_one_xevent): Check if we are iconified but don't have
9916 _NET_WM_STATE_HIDDEN. If do, treat as deiconify (Bug#9893).

9921 (x_term_init): Initialize dpyinfo->Xatom_net_wm_state_hidden.
9923 2011-10-29 Paul Eggert <eggert@cs.ucla.edu>
9925 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
9926 so that this new function doesn't get optimized away by a
9927 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
9929 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
9931 * frame.h (MOUSE_HL_INFO): Remove excess parens.
9933 2011-10-29 Eli Zaretskii <eliz@gnu.org>
9935 Fix the `xbytecode' command.
9936 * .gdbinit (xprintbytestr): New command.
9937 (xwhichsymbols): Rename from `which'; all callers changed.
9938 (xbytecode): Print the byte-code string as well.
9940 2011-10-29 Kim Storm <storm@cua.dk>
9942 * alloc.c (which_symbols): New function.
9944 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
9946 * minibuf.c (read_minibuf_noninteractive): Allow reading empty
9949 2011-10-29 Glenn Morris <rgm@gnu.org>
9951 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
9952 Not clear what it was for, and it causes various bugs. (Bug#9839)
9954 2011-10-28 Eli Zaretskii <eliz@gnu.org>
9956 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
9957 possible random value that matches one of those tested as
9958 condition to clear the mouse face.
9960 2011-10-28 Chong Yidong <cyd@gnu.org>
9962 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.
9964 2011-10-28 Dan Nicolaescu <dann@ics.uci.edu>
9966 * window.c (make_window): Initialize phys_cursor_on_p.
9968 2011-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
9970 * lisp.h (struct Lisp_Symbol): Update comments.
9972 2011-10-28 Juanma Barranquero <lekktu@gmail.com>
9974 * w32font.c (w32_load_unicows_or_gdi32): Add missing return.
9976 2011-10-28 Eli Zaretskii <eliz@gnu.org>
9978 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
9979 <oslsachem@gmail.com> for helping to debug this.
9981 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
9982 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
9983 (g_b_init_get_glyph_outline_w): New static variables.
9984 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
9985 (GetGlyphOutlineW_Proc): New typedefs.
9986 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
9987 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
9989 (w32font_open_internal, compute_metrics):
9990 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
9991 instead of calling the "wide" APIs directly.
9993 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
9995 * w32.h (syms_of_w32font): Add prototype.
9997 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
9999 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
10000 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
10001 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
10002 (Fmove_to_window_line): Doc fix.
10004 2011-10-27 Chong Yidong <cyd@gnu.org>
10006 * process.c (make_process): Set gnutls_state to NULL.
10008 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
10009 non-NULL, regardless of GNUTLS_INITSTAGE.
10010 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
10011 an error. Set process slots as soon as we allocate them.
10013 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
10015 2011-10-27 Chong Yidong <cyd@gnu.org>
10017 * gnutls.c (emacs_gnutls_deinit): New function.
10018 Deallocate credentials structures as well as calling gnutls_deinit.
10019 (Fgnutls_deinit, Fgnutls_boot): Use it.
10021 * process.c (make_process): Initialize GnuTLS credentials to NULL.
10022 (deactivate_process): Call emacs_gnutls_deinit.
10024 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
10026 * image.c (x_create_x_image_and_pixmap):

10031 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
10033 * w32fns.c (w32_default_color_map): New function,
10034 extracted from Fw32_default_color_map.
10035 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
10037 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
10039 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
10041 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
10043 * keyboard.c (test_undefined): New function (bug#9751).
10044 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
10046 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
10048 * sysdep.c (init_sys_modes): Fix the check for the controlling
10049 terminal (Bug#6649).
10051 2011-10-20 Eli Zaretskii <eliz@gnu.org>
10053 * dispextern.h (struct bidi_it): New member next_en_type.
10055 * bidi.c (bidi_line_init): Initialize the next_en_type member.
10056 (bidi_resolve_explicit_1): When next_en_pos is valid for the
10057 current character, check also for next_en_type being WEAK_EN.
10058 (bidi_resolve_weak): Don't enter the expensive loop if the current
10059 position is before next_en_pos. Record the bidi type of the first
10060 non-ET, non-BN character we find, in addition to its position.
10061 (bidi_level_of_next_char): Invalidate next_en_type when
10062 next_en_pos is over-stepped.
10064 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
10066 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
10067 * editfns.c: Rewrite current-time-zone so that it invokes
10068 the equivalent of (format-time-string "%Z") to get the time zone name.
10069 This fixes a bug when the time zone name contains characters that
10070 need converting from the system time locale to Emacs internal format.
10071 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
10072 that patch fixed format-time-string to do the conversion, but
10073 I forgot to fix current-time-zone.
10074 (format_time_string): New function, containing most of
10075 what Fformat_time_string used to contain.
10076 (Fformat_time_string): Rewrite in terms of format_time_string.
10077 This doesn't change this function's behavior.
10078 (current-time-zone): Rewrite to use format_time_string.
10079 This fixes the bug reported by Michael Schierl in
10080 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
10081 Jason Rumney's 2007-06-07 change worked around this bug, but
10083 * systime.h (tzname, timezone): Remove no-longer-used declarations.
10085 2011-10-19 Eli Zaretskii <eliz@gnu.org>
10087 * xdisp.c (start_display): If the character at POS is displayed
10088 via a display vector, reset IT->current.dpvec_index to zero.
10089 (try_window_reusing_current_matrix): If a line ends in a display
10090 vector or the next line starts in a display vector, continue
10091 redrawing the window even though the character position of
10092 start_row was reached.
10095 2011-10-18 Chong Yidong <cyd@gnu.org>
10097 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
10098 with nobreak-char-display too.
10100 2011-10-18 Eli Zaretskii <eliz@gnu.org>
10102 Fix part 3 of bug#9771.
10103 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
10104 (bidi_resolve_neutral): Don't enter the expensive loop looking for
10105 non-neutral characters if the current character is a paragraph
10106 separator (a.k.a. Newline). This avoids running the same
10107 expensive loop twice, once when we consume the preceding newline
10108 and the other time when the line actually needs to be displayed.
10109 Avoid the loop when we see neutrals on the base embedding level
10110 following a character whose directionality is the same as the
10111 paragraph's. This avoids running the expensive loop when a line
10112 ends in a long sequence of neutrals, like control characters.
10113 Add assertion against STRONG_AL type. Slightly rearrange code
10114 that determines the type of a neutral given the first non-neutral
10116 (bidi_level_of_next_char): Set next_en_pos to zero when
10117 invalidating its info.
10119 2011-10-17 Eli Zaretskii <eliz@gnu.org>
10121 * xdisp.c (push_display_prop): Determine whether to record string
10122 or buffer position by IT->string, not by IT->method. Allow
10123 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
10124 (move_it_vertically_backward): Don't look for character position
10125 immediately after the newline when in a continuation line.
10128 2011-10-15 Martin Rudalics <rudalics@gmx.at>
10130 * window.c (coordinates_in_window): Rewrite and delabelize
10131 vertical border check. (Bug#5357) (Bug#9618)
10133 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
10135 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
10136 errors in XSetWindowBorder (bug#9310).
10138 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
10140 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
10141 avoid crash when xmalloc overrun checking is enabled.
10143 2011-10-13 Eli Zaretskii <eliz@gnu.org>
10145 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
10146 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
10147 cursor motion with <left> and <right> arrow keys.
10149 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
10150 some callers set that themselves.
10152 2011-10-12 Eli Zaretskii <eliz@gnu.org>
10154 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
10155 display string and the previous row comes from the same string and
10156 is empty. (Bug#9739) (Bug#9738)
10158 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
10160 * doc.c (get_doc_string): Encode file name (bug#9735).
10162 2011-10-12 Eli Zaretskii <eliz@gnu.org>
10164 * bidi.c (bidi_level_of_next_char):
10165 * xdisp.c (get_visually_first_element): Remove old incorrect
10166 comments regarding the Unicode Line Separator character.
10168 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
10170 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
10172 * alloc.c (Fgc_status): Do not access beyond zombies array
10173 boundary if nzombies > MAX_ZOMBIES.
10174 * alloc.c (dump_zombies): Add missing format specifier.
10176 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
10178 * xdisp.c (set_cursor_from_row): Simplify conditionals,
10179 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
10181 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
10182 Some packages use them to denote characters with modifiers.
10184 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
10186 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
10187 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
10188 matching a pp-number. Rename parameter var to var1.
10190 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
10192 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
10194 2011-10-08 Glenn Morris <rgm@gnu.org>
10196 * callint.c (Fcall_interactively): Give a more explicit error for the
10197 'c' case with a non-character input. (Bug#8479)
10199 2011-10-08 Eli Zaretskii <eliz@gnu.org>
10201 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
10203 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
10204 lines that are hscrolled on the left.
10206 * dispnew.c (buffer_posn_from_coords): Account for a possible
10207 presence of header-line. (Bug#4426)
10209 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
10211 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
10212 Don't advertise functionality which we discourage or doesn't work.
10214 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
10216 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
10217 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
10218 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
10219 this makes Emacs dump core during garbage collection on rare
10220 occasions. sizeof is obviously inferior to offsetof here, so
10221 stick with offsetof.
10222 (GC_POINTER_ALIGNMENT): New macro.
10223 (mark_memory): Omit 3rd (offset) arg; caller changed.
10224 Don't assume EMACS_INT alignment is the same as pointer alignment.
10226 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
10228 * keyboard.c (read_key_sequence_remapped): New var.
10229 (read_key_sequence): Compute remapping in the right buffer.
10230 (command_loop_1): Use read_key_sequence's remapping directly.
10232 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
10234 * dired.c (file_name_completion): Don't expand file name.
10235 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
10236 before checking file name handler.
10238 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
10239 they've been requested explicitly (bug#9591).
10241 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
10243 * keymap.c (Fsingle_key_description): Use make_specified_string
10244 instead of build_string to build string from push_key_description.
10247 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
10249 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
10250 This fixes a Y2038 bug on 64-bit hosts.
10251 * buffer.c (reset_buffer):
10252 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
10253 (Fclear_buffer_auto_save_failure):
10254 Use 0, not -1, to represent an unset failure time, since time_t
10255 might not be signed.
10257 Remove dependency on glibc malloc internals.
10258 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
10259 Move back here from lisp.h, but with their new implementations.
10260 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
10261 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
10262 * charset.c (charset_table_init): New static var.
10263 (syms_of_charset): Use it instead of xmalloc. This removes a
10264 dependency on glibc malloc internals. See Eli Zaretskii's comment in
10265 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
10266 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
10267 Move back to alloc.c.
10268 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
10269 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
10271 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
10273 * nsterm.m (windowDidResize): Call x_set_window_size only when
10274 ns_in_resize is true. Otherwise set pixelwidth/height and
10275 call change_frame_size (Bug#9628).
10277 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
10279 Port --enable-checking=all to Fedora 14 x86-64.
10280 * charset.c (syms_of_charset): Also account for glibc malloc's
10281 internal overhead when calculating the initial malloc maximum.
10283 Port --enable-checking=all to Fedora 14 x86.
10284 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
10286 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
10287 (overrun_check_realloc, overrun_check_free):
10288 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
10289 That way, xmalloc returns a properly-aligned pointer even if
10290 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
10291 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
10292 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
10293 into account when calculating the initial malloc maximum.
10294 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
10295 Move here from alloc.c, so that charset.c can use it too.
10296 Properly align; the old code wasn't right for common 32-bit hosts
10297 when configured with --enable-checking=all.
10298 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
10299 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.

10308 * xdisp.c (compute_display_string_end): If there's no display
10309 string at CHARPOS, return -1.
10311 * bidi.c (bidi_fetch_char): When compute_display_string_end
10312 returns a negative value, treat the character as a normal
10313 character not covered by a display string. (Bug#9624)
10315 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
10317 * lread.c (Fread_from_string): Fix typo in docstring.
10319 2011-09-27 Eli Zaretskii <eliz@gnu.org>
10321 * xdisp.c (handle_invisible_prop): If invisible text ends on a
10322 newline, reseat the iterator instead of bidi-iterating there one
10323 character at a time. (Bug#9610)
10324 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
10325 TO_CHARPOS if the bidi iterator is at base embedding level.
10327 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
10329 * lread.c (readevalloop): Use correct code for NBSP.

10359 Default value is now t. Doc fix.
10361 * indent.c (Fvertical_motion): Compute and apply the overshoot
10362 logic when moving up, not only when moving down. Fix the
10363 confusing name and values of the it_overshoot_expected variable;
10364 logic changes accordingly. (Bug#9254) (Bug#9549)
10366 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
10367 CHARPOS is covered by a display string which includes newlines.
10368 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
10369 is covered by a display string with embedded newlines.
10371 2011-09-24 Michael Albinus <michael.albinus@gmx.de>

10380 do not ignore write error for any output size
10381 The previous change was incomplete.
10382 While it makes emacs --batch detect the vast majority of stdout
10383 write failures, errors were still ignored whenever the output size is
10384 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
10385 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
10386 && echo FAIL: ignored write error
10387 FAIL: ignored write error
10388 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
10389 && echo FAIL: ignored write error
10390 FAIL: ignored write error

10408 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
10409 a display string, extend search for cursor position to end of row.
10410 (find_row_edges): If the row ends in a newline from a display
10411 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
10412 Handle the case of a display string with multiple newlines.
10413 (Fcurrent_bidi_paragraph_direction): Fix search for previous
10414 non-empty line. Fixes confusing cursor motion with arrow keys at
10415 the beginning of a line that starts with whitespace.

10425 boolean (Bug#9154).
10427 2011-09-18 Eli Zaretskii <eliz@gnu.org>
10429 * xdisp.c (display_line): Record maximum and minimum buffer
10430 positions even if no glyphs were produced (e.g., by a zero-width
10431 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
10432 buffer positions that will be removed from the glyph row because
10434 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
10435 column is beyond frame width: don't subtract 1 "pixel" when
10436 computing width of the stretch.
10437 (reseat_at_next_visible_line_start): Undo the change made on
10438 2011-09-17 that saved paragraph information and restored it after
10439 the call to `reseat'. (Bug#9545)
10441 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>

10475 2011-09-17 Eli Zaretskii <eliz@gnu.org>
10477 * xdisp.c (reseat_at_next_visible_line_start): Keep information
10478 about the current paragraph and restore it after the call to reseat.
10480 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
10481 (bidi_find_paragraph_start): Search back for paragraph beginning
10482 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
10483 (bidi_move_to_visually_next): Only trigger paragraph-related
10484 computations when the last character is a newline or at EOB, not
10485 just any NEUTRAL_B. (Bug#9470)
10487 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
10488 truncated lines if point is covered by a display string. (Bug#9524)
10490 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
10492 * xselect.c: Relax test for outgoing X longs (Bug#9498).
10493 (cons_to_x_long): New function.
10494 (lisp_data_to_selection_data): Use it. Correct the test for
10495 short-versus-long data; it was negated. Break out of vector
10496 loop, for efficiency, when a long datum is discovered.
10498 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
10500 * eval.c (Fquote): Document its non-consing behavior (bug#9482).

10529 This occurs when processing a multibyte format.
10530 Problem reported by Wolfgang Jenker.
10532 2011-09-15 Johan Bockgård <bojohan@gnu.org>
10534 * xdisp.c (try_cursor_movement): Only check for exact match if

10537 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
10539 Remove unused external symbols.
10540 * dispextern.h (calc_pixel_width_or_height): Remove decl.
10541 * xdisp.c (calc_pixel_width_or_height): Now static.

10547 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
10549 * xselect.c: Use signed conversions more consistently (Bug#9498).
10550 (selection_data_to_lisp_data): Assume incoming selection data are
10551 signed integers, not unsigned. This is to be consistent with
10552 outgoing selection data, which was modified to use signed integers
10553 in as part of the fix to Bug#9196 in response to Jan D.'s comment
10554 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
10555 expects long, not unsigned long.
10557 2011-09-14 Eli Zaretskii <eliz@gnu.org>
10559 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
10560 computation of loop end. Reported by Johan Bockgård
10563 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
10565 * frame.c (Fother_visible_frames_p): Function deleted.
10567 2011-09-12 Eli Zaretskii <eliz@gnu.org>
10569 * indent.c (compute_motion): Process display vector front to back
10570 rather than the other way around. (Bug#2496)
10572 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
10574 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
10576 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
10578 * minibuf.c (Fread_from_minibuffer): Doc fix.
10580 2011-09-11 Eli Zaretskii <eliz@gnu.org>
10582 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
10583 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
10585 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
10587 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
10588 value for non-existent files.
10590 2011-09-11 Eli Zaretskii <eliz@gnu.org>
10592 * fileio.c (Finsert_file_contents): If the file cannot be opened,
10593 set its "size" to -1. This will set the modtime_size field of
10594 the corresponding buffer to -1, which is what
10595 verify-visited-file-modtime expects for files that do not exist.
10598 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
10600 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
10602 * lisp.h: ... from here. push_key_description is no longer
10603 defined in keyboard.c, so its declaration should not be in
10604 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
10605 logically belongs with push_key_description.
10607 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
10609 * buffer.h: Include <sys/types.h> instead of <time.h>.
10610 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
10611 Problem reported by Herbert J. Skuhra.
10613 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
10615 * xml.c (parse_region): Make the parsing work for
10616 non-comment-starting XML files again (bug#9144).
10618 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
10620 * image.c (gif_load): Fix calculation of bottom and right corner.
10623 2011-09-10 Eli Zaretskii <eliz@gnu.org>
10625 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
10626 redisplay in small windows.
10628 2011-09-09 Eli Zaretskii <eliz@gnu.org>
10630 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
10632 2011-09-08 Martin Rudalics <rudalics@gmx.at>
10634 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
10635 Operate on live windows only.
10637 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
10639 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
10641 2011-09-07 Eli Zaretskii <eliz@gnu.org>
10643 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
10644 only under bidi iteration.
10646 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
10648 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
10650 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
10652 isnan: Fix porting problem to Solaris 10 with bundled gcc.
10653 Without this fix, the command to link temacs failed due to an
10654 undefined symbol __builtin_isnan. This is because
10655 /usr/include/iso/math_c99.h #defines isnan(x) to
10656 __builtin_isnan(x), but the bundled gcc, which identifies itself
10657 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
10659 * floatfns.c (isnan): #undef, and then #define to a clone of
10661 (Fisnan): Always define, since it's always available now.
10662 (syms_of_floatfns): Always define isnan at the Lisp level.
10664 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
10666 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
10668 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
10670 * fileio.c: Fix bugs with large file offsets (Bug#9428).
10671 The previous code assumed that file offsets (off_t values) fit in
10672 EMACS_INT variables, which is not true on typical 32-bit hosts.
10673 The code messed up by falsely reporting buffer overflow in cases
10674 such as (insert-file-contents "big" nil 1 2) into an empty buffer
10675 when "big" contains more than 2**29 bytes, even though this
10676 inserts just one byte and does not overflow the buffer.
10677 (Finsert_file_contents): Store file offsets as off_t
10678 values, not as EMACS_INT values. Check for overflow when
10679 converting between EMACS_INT and off_t. When checking for
10680 buffer overflow or for overlap, take the offsets into account.
10681 Don't use EMACS_INT for small values where int suffices.
10682 When checking for overlap, fix a typo: ZV was used where
10683 ZV_BYTE was intended.
10684 (Fwrite_region): Don't assume off_t fits into 'long'.
10685 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
10687 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
10689 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
10691 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
10693 sprintf-related integer and memory overflow issues (Bug#9412).
10695 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
10696 (esprintf, exprintf, evxprintf): New functions.
10697 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
10698 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
10699 (modify_event_symbol): Do not assume that the length of
10700 name_alist_or_stem is safe to alloca and fits in int.
10701 (Fexecute_extended_command): Likewise for function name and binding.
10702 (Frecursion_depth): Wrap around reliably on integer overflow.
10703 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
10704 since some callers pass EMACS_INT values.
10705 (Fsingle_key_description): Don't crash if symbol name contains more
10706 than MAX_ALLOCA bytes.
10707 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
10708 (get_minibuffer): Arg is now EMACS_INT, not int.
10709 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
10710 (esprintf, exprintf, evxprintf): New decls.
10711 * window.h (command_loop_level, minibuf_level): Reflect API changes.
10713 * dbusbind.c (signature_cat): New function.
10714 (xd_signature, Fdbus_register_signal):
10715 Do not overrun buffer; instead, report string overflow.
10717 * dispnew.c (add_window_display_history): Don't overrun buffer.
10718 Truncate instead; this is OK since it's just a log.
10720 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
10721 even if the time zone offset is outlandishly large.
10722 Don't mishandle offset == INT_MIN.
10724 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
10725 when creating daemon; the previous buffer-overflow check was incorrect.
10727 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
10728 which has the guts of the old verror function.
10730 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
10731 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
10733 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
10734 (font_unparse_xlfd): Don't blindly alloca long strings.
10735 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
10736 fits in int, when using sprintf. Use single snprintf to count
10737 length of string rather than counting it via multiple sprintfs;
10738 that's simpler and more reliable.
10739 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
10740 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
10741 sprintf, in case result does not fit in int.
10743 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
10744 (fontset_from_font): Print it.
10746 * frame.c (tty_frame_count): Now printmax_t, not int.
10747 (make_terminal_frame, set_term_frame_name): Print it.
10748 (x_report_frame_params): In X, window IDs are unsigned long,
10749 not signed long, so print them as unsigned.
10750 (validate_x_resource_name): Check for implausibly long names,
10751 and don't assume name length fits in 'int'.
10752 (x_get_resource_string): Don't blindly alloca invocation name;
10753 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
10756 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
10757 (xg_check_special_colors, xg_set_geometry):
10758 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
10760 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
10761 Use esprintf, not sprintf, in case result does not fit in int.
10763 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
10764 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
10765 it as a large positive number.
10766 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
10767 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
10769 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
10770 in case result does not fit in int.
10772 * print.c (float_to_string): Detect width overflow more reliably.
10773 (print_object): Make sprintf buffer a bit bigger, to avoid potential
10774 buffer overrun. Don't assume list length fits in 'int'. Treat
10775 print length of 0 as 0, not as infinity; to be consistent with other
10776 uses of print length in this function. Don't overflow print length
10777 index. Don't assume hash table size fits in 'long', or that
10778 vectorlike size fits in 'unsigned long'.
10780 * process.c (make_process): Use printmax_t, not int, to format
10781 process-name gensyms.
10783 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
10785 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
10786 to avoid potential buffer overrun.
10788 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
10789 if X resource line is longer than 512 bytes.
10791 * xfns.c (x_window): Make sprintf buffer a bit bigger
10792 to avoid potential buffer overrun.
10794 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
10796 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
10798 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
10800 Integer overflow fixes for scrolling, etc.
10801 Without these, Emacs silently mishandles large integers sometimes.
10802 For example, "C-u 4294967297 M-x recenter" was treated as if
10803 it were "C-u 1 M-x recenter" on a typical 64-bit host.
10805 * xdisp.c (try_window_id): Check Emacs fixnum range before
10806 converting to 'int'.
10808 * window.c (window_scroll_line_based, Frecenter):
10809 Check that an Emacs fixnum is in range before assigning it to 'int'.
10810 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
10811 values converted from Emacs fixnums.
10812 (Frecenter): Don't wrap around a line count if it is out of 'int'
10813 range; instead, treat it as an extreme value.
10814 (Fset_window_configuration, compare_window_configurations):
10815 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
10817 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
10818 that can exceed INT_MAX. Check that EMACS_INT value is in range
10819 before assigning it to the (possibly-narrower) index.
10820 (match_limit): Don't assume that a fixnum can fit in 'int'.
10822 * print.c (print_object): Use ptrdiff_t, not int, for index that can
10825 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
10826 (Fvertical_motion): Don't wrap around LINES values that don't fit
10827 in 'int'. Instead, treat them as extreme values. This is good
10828 enough for windows, which can't have more than INT_MAX lines anyway.
10830 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
10832 * Require libxml/parser.h to avoid compilation warning.
10834 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
10836 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
10837 since this reportedly can destroy thread storage.
10839 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
10841 * syntax.c (find_defun_start): Update all cache variables if
10842 exiting early (Bug#9401).
10844 2011-08-30 Eli Zaretskii <eliz@gnu.org>
10846 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
10848 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
10849 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
10850 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
10852 * term.c (tty_append_glyph): New function.
10853 (produce_stretch_glyph): Static function and its prototype deleted.
10855 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
10858 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
10860 * image.c (parse_image_spec): Check for nonnegative, not for positive,
10861 when checking :margin (Bug#9390).
10862 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
10863 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
10864 so that the name doesn't mislead. All uses changed.
10866 2011-08-28 Johan Bockgård <bojohan@gnu.org>
10868 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
10871 2011-08-27 Eli Zaretskii <eliz@gnu.org>
10873 * xdisp.c (move_it_to): Don't bail out early when reaching
10874 position beyond to_charpos, if we are scanning backwards.
10875 (move_it_vertically_backward): When DY == 0, make sure we get to
10876 the first character in the line after the newline.
10878 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
10880 * ccl.c: Improve and simplify overflow checking (Bug#9196).
10881 (ccl_driver): Do not generate an out-of-range pointer.
10882 (Fccl_execute_on_string): Remove unnecessary check for
10883 integer overflow, noted by Stefan Monnier in
10884 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
10885 Remove a FIXME that didn't need fixing.
10886 Simplify the newly-introduced buffer reallocation code.
10888 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
10890 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
10892 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
10894 Integer and memory overflow issues (Bug#9196).
10896 * doc.c (get_doc_string): Rework so that
10897 get_doc_string_buffer_size is the actual buffer size, rather than
10898 being 1 less than the actual buffer size; this makes xpalloc more
10901 * image.c (x_allocate_bitmap_record, cache_image):
10902 * xselect.c (Fx_register_dnd_atom):
10903 Simplify previous changes by using xpalloc.
10905 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
10906 since either will do and ptrdiff_t is convenient with xpalloc.
10908 * charset.c (charset_table_size)
10909 (struct charset_sort_data.priority): Now ptrdiff_t.
10910 (charset_compare): Don't overflow if priorities differ greatly.
10911 (Fsort_charsets): Don't assume list length fits in int.
10912 Check for size-calculation overflow when allocating sort data.
10913 (syms_of_charset): Allocate an initial charset table that is
10914 just under 64 KiB, to avoid problems with glibc malloc and mmap.
10916 * cmds.c (internal_self_insert): Check for size-calculation overflow.
10918 * composite.h (struct composition.glyph_len): Now int, not unsigned.
10919 The actual value is always <= INT_MAX, and leaving it unsigned made
10920 overflow checking harder.
10922 * dispextern.h (struct glyph_matrix.rows_allocated)
10923 (struct face_cache.size): Now ptrdiff_t, for convenience in use
10924 with xpalloc. The values are still always <= INT_MAX.
10926 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
10928 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
10929 (SAFE_NALLOCA): New macro.
10931 * region-cache.c (struct boundary.pos, find_cache_boundary)
10932 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
10933 (set_cache_region, invalidate_region_cache)
10934 (revalidate_region_cache, know_region_cache, region_cache_forward)
10935 (region_cache_backward, pp_cache):
10936 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
10937 so that ptrdiff_t * can be passed to xpalloc.
10938 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
10939 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
10940 (pp_cache): Don't assume cache_len fits in int.
10941 * region-cache.h: Adjust extern decls to match.
10943 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
10944 EMACS_INT, since either will do, for xpalloc.
10946 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
10947 (xnmalloc, xnrealloc, xpalloc): New functions.
10949 * bidi.c (bidi_shelve_header_size): New constant.
10950 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
10951 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
10953 * bidi.c (bidi_cache_shrink):
10954 * buffer.c (overlays_at, overlays_in, record_overlay_string)
10956 Don't update size of array until after memory allocation succeeds,
10957 because xmalloc/xrealloc may not return.
10958 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
10959 now that we have proper integer overflow checking.
10960 (record_overlay_string, overlay_strings): Catch overflows when
10961 calculating size of overlay_str_buf.
10963 * callproc.c (Fcall_process): Check for size overflow when
10964 calculating size of args2.
10965 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
10966 Normally we prefer signed values, but sticking with ptrdiff_t would
10967 require adding more-complicated checks.
10969 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
10970 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
10971 Redo buffer-overflow calculations to avoid integer overflow.
10972 Add a FIXME comment where memory seems to be over-allocated.
10974 * character.c (Fstring): Check for size-calculation overflow.
10976 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
10977 unnecessary integer overflow. Check for size overflow.
10978 (encode_coding_object): Don't update size until xmalloc succeeds.
10980 * composite.c (get_composition_id): Check for overflow in glyph
10981 length calculations.
10983 Integer and memory overflow fixes for display code.
10984 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
10985 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
10986 (scrolling_window): Check for overflow in size calculations.
10987 (line_draw_cost, realloc_glyph_pool, add_row_entry):
10988 Don't assume glyph table len fits in int.

10990 (row_table_size): Now ptrdiff_t, not int.
10991 (scrolling_window): Avoid overflow in size calculations.
10992 Don't update size until allocation succeeds.
10993 * fns.c (concat): Check for overflow in size calculations.
10994 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
10995 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.

10998 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
10999 (get_doc_string): Check for size calculation overflow.
11000 Don't update size until allocation succeeds.
11001 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
11002 EMACS_INT, where ptrdiff_t will do.
11003 (Fsubstitute_command_keys): Check for string overflow.
11005 * editfns.c (set_time_zone_rule): Don't assume environment length
11007 (message_length): Now ptrdiff_t, not int.
11008 (Fmessage_box): Don't update size until allocation succeeds.
11009 Don't assume message length fits in int.
11010 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
11012 * emacs.c (main): Do not reallocate argv, since there is a null at
11013 the end that can be overwritten, and this way there's no need to
11014 worry about size-calculation overflow.
11015 (sort_args): Check for size-calculation overflow.
11017 * eval.c (init_eval_once, grow_specpdl): Don't update size until
11019 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
11021 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
11022 (x_set_scroll_bar_width, x_figure_window_size):
11023 Check for integer overflow.
11024 (x_set_alpha): Do not assume XINT fits in int.
11026 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
11027 This is for the members text_lines, text_cols, total_lines, total_cols,
11028 where the system imposes an 'int' limit.
11030 * fringe.c (Fdefine_fringe_bitmap):
11031 Don't update size until alloc works.
11033 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
11034 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
11036 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
11037 Check for size-calculation overflow.
11038 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
11039 do, as we prefer signed integers.
11040 (id_to_widget.max_size, id_to_widget.used)
11041 (xg_store_widget_in_map, xg_remove_widget_from_map)
11042 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
11043 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
11044 Use and return ptrdiff_t, not int.
11045 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
11046 * gtkutil.h: Change prototypes to match the above.
11048 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
11049 are duplicate now that they've been promoted to lisp.h.
11050 (x_allocate_bitmap_record, x_alloc_image_color)
11051 (make_image_cache, cache_image, xpm_load):
11052 Don't update size until alloc is done.
11053 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
11055 Check for size calculation overflow.
11056 (ct_colors_allocated_max): New constant.
11057 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid
11060 * keyboard.c (read_char, menu_bar_items, tool_bar_items)
11061 (read_char_x_menu_prompt, read_char_minibuf_menu_width)
11062 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
11063 Use ptrdiff_t, not int, to count maps.
11064 (read_char_minibuf_menu_prompt): Check for overflow in size
11065 calculations. Don't update size until allocation succeeds.
11066 Redo calculations to avoid overflow.
11067 * keyboard.h: Change prototypes to match the above.
11069 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
11071 (current_minor_maps): Check for size calculation overflow.
11072 * keymap.h: Change prototypes to match the above.
11074 * lread.c (read1, init_obarray): Don't update size until alloc done.
11076 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.
11077 (store_kbd_macro_char): Reorder multiplicands to avoid overflow.
11079 * nsterm.h (struct ns_color_table.size, struct ns_color_table.avail):
11080 Now ptrdiff_t, not int.
11081 * nsterm.m (ns_index_color): Use ptrdiff_t, not int, for table indexes.

11087 * region-cache.c (move_cache_gap): Check for size calculation overflow.
11089 * scroll.c (do_line_insertion_deletion_costs): Check for size calc

11093 (Fset_match_data): Don't assume list lengths fit in 'int'.
11095 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
11096 for command line length. Do not attempt to address one before the
11097 beginning of an array, as that's not portable.
11099 * term.c (max_frame_lines): Remove; unused.
11100 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
11102 (encode_terminal_code, calculate_costs): Check for size
11103 calculation overflow.

11106 done. Redo calculations to avoid overflow.
11107 (calculate_costs): Don't bother calling xmalloc when xrealloc will do.
11109 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
11110 subtracting pointers.
11111 (gobble_line): Check for overflow more carefully. Don't update size
11114 * tparam.c (tparam1): Use ptrdiff_t, not int, for sizes.

11125 Use ptrdiff_t, not int, for sizes.
11126 (Finternal_make_lisp_face, cache_face):
11127 Check for size calculation overflow.
11128 (cache_face): Treat size calculation overflows as if they were
11129 memory exhaustion (the usual treatment), rather than aborting.
11131 * xfns.c (x_encode_text, x_set_name_internal)
11132 (Fx_change_window_property): Use ptrdiff_t, not int, to count
11133 sizes, since they can exceed INT_MAX in size. Check for size
11134 calculation overflow.
11136 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
11137 (xg_select): Check for size calculation overflow.
11138 Don't update size until alloc done.
11140 * xrdb.c (get_environ_db): Don't assume path length fits in int,
11141 as sprintf is limited to int lengths.
11143 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
11144 (X_LONG_MIN): New macros.
11145 Use them to make the following changes clearer.
11146 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
11147 This change doesn't affect the value now, but it may help remind
11148 future maintainers not to raise the value too much later.
11149 (SELECTION_QUANTUM): Remove, replacing with ...
11150 (selection_quantum): ... new function, which avoids overflow.
11152 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
11153 assumption that selection length fits in 'int'.
11154 (x_reply_selection_request, x_handle_selection_request)
11155 (x_get_window_property, receive_incremental_selection)
11156 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
11157 (lisp_data_to_selection_data, clean_local_selection_data):

11159 (x_reply_selection_request, x_get_window_property)
11160 (receive_incremental_selection, x_property_data_to_lisp):
11161 Redo calculations to avoid overflow.
11162 (x_reply_selection_request): When sending hint, ceiling it at
11163 X_LONG_MAX rather than relying on wraparound overflow to send
11165 (x_get_window_property, receive_incremental_selection)
11166 (lisp_data_to_selection_data, x_property_data_to_lisp):
11167 Check for size-calculation overflow.
11168 (x_get_window_property, receive_incremental_selection)
11169 (lisp_data_to_selection_data, Fx_register_dnd_atom):
11170 Don't store size until memory allocation succeeds.
11171 (x_get_window_property): Plug memory leak on memory exhaustion.
11172 Don't double-block input; malloc is safe here. Don't assume 2**34
11173 - 4 fits in unsigned long. Add an xassert to check
11174 XGetWindowProperty overflow. Be more careful about overflow
11175 calculations, and distinguish size from memory overflow better.
11176 (receive_incremental_selection): When tracing, don't assume
11177 unsigned int is less than INT_MAX.
11178 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
11179 harmful) conversions of unsigned short to int.
11180 (lisp_data_to_selection_data): Don't assume that integers
11181 in the range -65535 through -1 fit in an X unsigned short.
11182 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
11183 result parameters unless successful. Rely on cons_to_unsigned
11184 to report problems with elements; the old code wasn't right anyway.
11185 (x_check_property_data): Check for int overflow; we cannot use
11186 a wider type due to X limits.
11187 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
11189 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.
11191 * xterm.c (x_color_cells, x_send_scrollbar_event, handle_one_xevent)
11192 (x_term_init): Check for size calculation overflow.
11193 (x_color_cells): Don't store size until memory allocation succeeds.
11194 (handle_one_xevent): Use ptrdiff_t, not int, for byte counts.
11195 Don't assume alloca size is less than MAX_ALLOCA.

11218 * image.c (xpm_get_color_table_h):
11219 * lisp.h (hash_lookup, hash_put):
11220 * minibuf.c (Ftest_completion):
11221 Use ptrdiff_t for hash table indexes, not int (which is too
11222 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
11223 32-bit --with-wide-int hosts).
11225 * charset.c (Fdefine_charset_internal): Check for integer overflow.
11226 Add a FIXME comment about memory leaks.
11227 (syms_of_charset): Don't assume xmalloc returns.
11229 Don't assume that stated character widths fit in int.

11231 * character.h (CHAR_WIDTH):
11232 * indent.c (MULTIBYTE_BYTES_WIDTH):
11233 Use sanitize_char_width to avoid undefined and/or bad behavior
11234 with outlandish widths.
11235 * character.h (sanitize_tab_width): Rename from sanitize_width,
11236 now that we have two such functions. All uses changed.

11248 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
11250 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
11251 Remove unreachable code.
11252 (read_hex, load_charset_map_from_file): Check for integer overflow.
11254 * xterm.c: Don't go over XClientMessageEvent limit.
11255 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
11256 (x_send_scroll_bar_event): Likewise. Check that the size does not
11257 exceed limits imposed by XClientMessageEvent, as well as the usual
11258 ptrdiff_t and size_t limits.
11260 * keyboard.c: Overflow, signedness and related fixes.
11261 (make_lispy_movement): Use same integer type in forward decl
11262 that is used in the definition.
11263 (read_key_sequence, keyremap_step):
11264 Change bufsize argument back to int, undoing my 2011-03-30 change.
11265 We prefer signed types, and int is wide enough here.
11266 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
11267 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
11268 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
11269 length, not size_t. Use ptrdiff_t for index, not int.
11270 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
11271 possibility of integer overflow.
11273 Overflow, signedness and related fixes for images.

11294 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
11295 (lookup_image): Remove unnecessary tests.
11296 (xbm_image_p): Locals are now of int, not EMACS_INT,
11297 since parse_image_check makes sure they fit into int.
11298 (png_load, gif_load, svg_load_image):
11299 Prefer int to unsigned where either will do.
11300 (tiff_handler): New function, combining the cores of the
11301 old tiff_error_handler and tiff_warning_handler.
11302 This function is rewritten to use vsnprintf and thereby avoid
11303 stack buffer overflows. It uses only the features of vsnprintf
11304 that are common to both POSIX and native Microsoft.
11305 (tiff_error_handler, tiff_warning_handler): Use it.
11306 (tiff_load, gif_load, imagemagick_load_image):
11307 Don't assume :index value fits in 'int'.
11308 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
11309 (imagemagick_load_image): Check that crop parameters fit into
11310 the integer types that MagickCropImage accepts. Don't assume
11311 Vimagemagick_render_type has a nonnegative value. Don't assume
11312 size_t fits in 'long'.
11313 (gs_load): Use printmax_t to print the widest integers possible.
11314 Check for integer overflow when computing image height and width.

11326 handle_single_display_spec, not just 1 or zero.
11327 (handle_single_display_spec): If the display spec is of the form
11328 `(space ...)', and specifies display in the text area, return 2
11330 (try_cursor_movement): Check for the need to scroll more
11331 accurately, and prefer exact match for point under bidi.
11332 Don't advance `row' beyond the last row of the window.
11334 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
11335 into disp_prop; all users changed.
11337 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
11338 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
11339 for the text covered by the display property.

11349 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
11350 buffers, return left-to-right.
11351 (set_cursor_from_row): Consider candidate row a win if its glyph
11352 represents a newline and point is on that newline. Fixes cursor
11353 positioning on the newline at EOL of R2L text within L2R
11354 paragraph, and vice versa.
11355 (try_cursor_movement): Check continued rows, in addition to
11356 continuation rows. Fixes unwarranted scroll when point enters a
11357 continued line of R2L text within an L2R paragraph, or vice versa.
11358 (cursor_row_p): Consider the case of point being equal to
11359 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
11360 from the end of a short line to the beginning of a continued line
11361 of R2L text within L2R paragraph.
11362 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
11363 composed characters.

11378 2011-08-22 Kenichi Handa <handa@m17n.org>
11380 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
11381 extra slot even if the purpose is char-code-property-table.
11383 2011-08-23 Eli Zaretskii <eliz@gnu.org>
11385 * xdisp.c (redisplay_window): When computing centering_position,
11386 account for the height of the header line. (Bug#8874)
11388 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
11389 instead of CHAR_TO_BYTE. Fixes a crash when a completion
11390 candidate is selected by the mouse, and that candidate has a
11391 composed character under the mouse.
11393 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
11394 coordinates reported by pos-visible-in-window-p for a composed
11395 character in column zero.
11397 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
11399 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
11401 2011-08-22 Eli Zaretskii <eliz@gnu.org>
11403 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
11404 consider it a hit if to_charpos is anywhere in the range of the
11405 composed buffer positions.
11407 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
11409 * image.c (gif_load): Don't assume that each subimage has the same
11410 dimensions as the base image. Handle disposal method that is
11411 "undefined" by the gif spec (Bug#9335).
11413 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
11415 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

11418 2011-08-19 Eli Zaretskii <eliz@gnu.org>
11420 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
11421 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
11422 from an Org mode buffer to a Speedbar frame.
11424 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
11425 a composition, take its buffer position from IT->cmp_it.charpos.
11426 Fixes cursor positioning at the beginning of a line that begins
11427 with a composed character.
11429 2011-08-18 Eli Zaretskii <eliz@gnu.org>
11431 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
11432 character bidirectional type, use STRONG_L instead. Fixes crashes
11433 in a buffer produced by `describe-categories'.
11435 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
11436 members before the level stack, so they would be saved and
11437 restored when copying iterator state. Fixes incorrect reordering
11438 around TABs covered by display properties.
11440 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
11442 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

11455 2011-08-16 Ken Brown <kbrown@cornell.edu>
11457 * gmalloc.c: Expand comment.
11459 2011-08-16 Eli Zaretskii <eliz@gnu.org>
11461 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
11462 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.

11507 * process.c (create_process): Call setup_process_coding_systems
11508 after the pid of the process is set to -1 (Bug#8162).
11510 2011-08-14 Eli Zaretskii <eliz@gnu.org>
11512 * xdisp.c (move_it_in_display_line_to): Don't invoke
11513 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
11514 ppos_it. Fixes vertical cursor motion when line beginning is
11515 covered by an image. (Bug#9296)
11517 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
11519 * nsterm.h (ns_run_ascript): Declare.

11523 (ns_run_ascript): New function.
11524 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
11525 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
11526 the event loop. Get status from as_status (Bug#7276).
11528 * nsterm.m (sendEvent): If event is NSApplicationDefined and
11529 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
11530 the event loop (Bug#7276).
11532 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>

11555 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
11556 (Fnetwork_interface_list): Allocate in increments of bytes instead
11557 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
11558 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
11560 (struct ifflag_def): notrailers is smart on OSX.
11561 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
11562 Get hardware address with getifaddrs if available.
11564 2011-08-12 Eli Zaretskii <eliz@gnu.org>
11566 * xdisp.c (iterate_out_of_display_property): xassert that
11567 IT->position is set to within IT->object's boundaries. Break from
11568 the loop as soon as EOB is reached; avoids infloops in redisplay

11570 Set IT->current to match the bidi iterator unconditionally.
11571 (push_display_prop): Allow GET_FROM_STRING as IT->method on
11572 entry. Force push_it to save on the stack the current
11573 buffer/string position, to be restored by pop_it. Fix flags in
11574 the iterator structure wrt the object coming from a display
11575 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
11576 properties. (Bug#9284)
11578 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
11580 * fontset.c (fontset_get_font_group): Add proper type checks.

11593 no-display-properties-and-no-overlays under bidi display.
11594 Set disp_pos in the bidi iterator to avoid searches for display
11595 properties and overlays.
11597 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
11599 * editfns.c (Fset_time_zone_rule): Document relationship with the

11605 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
11607 * composite.c (autocmp_chars): Don't reset point. That is done by
11608 restore_point_unwind (Bug#5984).
11610 2011-08-07 Juri Linkov <juri@jurta.org>
11612 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
11613 to show the arg `TIME' instead of `TIMEVAL'.
11615 2011-08-06 Eli Zaretskii <eliz@gnu.org>
11617 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
11618 display property strides EOL and includes a newline, as in
11619 longlines-mode. (Bug#9254)
11620 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
11621 word-wrap under bidirectional display. (Bug#9224)
11623 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
11624 is non-zero, even if the data buffer is NULL. Fixes a crash in
11625 vertical-motion with longlines-mode. (Bug#9254)
11627 2011-08-05 Eli Zaretskii <eliz@gnu.org>
11629 * bidi.c <bidi_cache_total_alloc>: Now static.
11630 (bidi_initialize): Initialize bidi_cache_total_alloc.
11632 * xdisp.c (display_line): Release buffer allocated for shelved bidi
11635 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
11636 amount allocated this far in `bidi_cache_total_alloc'.
11637 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
11638 non-zero, only free the data buffer without restoring the cache
11639 contents. All callers changed.
11641 * dispextern.h (bidi_unshelve_cache): Update prototype.
11643 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
11644 (move_it_in_display_line, move_it_to)
11645 (move_it_vertically_backward, move_it_by_lines): Replace the call
11646 to xfree to an equivalent call to bidi_unshelve_cache.
11647 (move_it_in_display_line_to): Fix logic of returning
11648 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
11650 2011-08-05 Eli Zaretskii <eliz@gnu.org>
11652 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
11653 came from a string character with a `cursor' property. (Bug#9229)
11655 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
11657 * Makefile.in (LIB_PTHREAD): New variable.
11658 (LIBES): Add LIB_PTHREAD (Bug#9216).
11660 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
11661 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
11663 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
11665 * regex.c (re_iswctype): Remove some redundant boolean conversions.
11667 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
11669 * xterm.c (x_find_topmost_parent): New function.
11670 (x_set_frame_alpha): Find topmost parent window with
11671 x_find_topmost_parent and set the property there also (bug#9181).
11672 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
11674 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
11676 * callproc.c (Fcall_process): Avoid vfork clobbering
11677 the local vars buffer, coding_systems, current_dir.
11679 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
11681 * keymap.c (Fmake_composed_keymap): Move to subr.el.
11683 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
11685 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
11686 so that it is not optimized away.
11688 * xdisp.c (compute_display_string_pos): Remove unused local.
11690 2011-08-02 Eli Zaretskii <eliz@gnu.org>
11692 Fix slow cursor motion and scrolling in large buffers with
11693 selective display, like Org Mode buffers. (Bug#9218)
11695 * dispextern.h (struct bidi_it): New member disp_prop_p.
11697 * xdisp.c: Remove one-slot cache of display string positions.
11698 (compute_display_string_pos): Accept an additional argument
11699 DISP_PROP_P; callers changed. Scan at most 5K characters forward
11700 for a display string or property. If found, set DISP_PROP_P
11703 * bidi.c (bidi_fetch_char): Accept an additional argument
11704 DISP_PROP_P, and pass it to compute_display_string_pos.
11705 Only handle text covered by a display string if DISP_PROP_P is returned
11706 non-zero. All callers of bidi_fetch_char changed.
11708 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
11710 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
11712 2010-12-03 Don March <don@ohspite.net>
11714 * keymap.c (Fdefine_key): Fix non-prefix key error message when
11715 last character M-[char] is translated to ESC [char] (bug#7541).
11717 2011-08-02 Kenichi Handa <handa@m17n.org>
11719 * lisp.h (uniprop_table): Extern it.
11721 * chartab.c (uniprop_table): Make it non-static.
11723 2011-08-01 Eli Zaretskii <eliz@gnu.org>
11725 * xdisp.c (forward_to_next_line_start): Accept additional argument
11726 BIDI_IT_PREV, and store into it the state of the bidi iterator had
11728 (reseat_at_next_visible_line_start): Use the bidi iterator state
11729 returned by forward_to_next_line_start to restore the state of
11730 it->bidi_it after backing up to previous newline. (Bug#9212)
11732 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
11734 * regex.c (re_comp): Protoize.
11735 (re_exec): Fix return type.
11736 (regexec): Fix type of `ret'. (Bug#9203)
11738 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
11740 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
11741 This is needed if max-image-size is a floating-point number.
11743 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
11745 * print.c (print_object): Print empty symbol as ##.
11747 * lread.c (read1): Read ## as empty symbol.
11749 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
11751 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
11752 setting frame foreground color (Bug#9175).
11753 (x_set_background_color): Likewise.
11755 * nsmenu.m (-setText): Size tooltip dimensions precisely to
11756 contents (Bug#9176).
11757 (EmacsTooltip -init): Remove bezels and add shadows to
11760 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
11761 or scroll bar (Bug#8470).
11763 * nsfont.m (nsfont_open): Remove assignment to voffset and
11764 unnecessary vars hshink, expand, hd, full_height, min_height.
11765 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
11767 * nsterm.h (nsfont_info): Remove voffset field.
11769 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
11771 Implement strike-through and overline on NextStep (Bug#8863).
11773 * nsfont.m (nsfont_open): Use underline position provided by font,
11774 instead of hard-coded value of 2.
11775 (nsfont_draw): Call ns_draw_text_decoration instead.
11777 * nsterm.h: Add declaration for ns_draw_text_decoration.
11779 * nsterm.m (ns_draw_text_decoration): New function for drawing
11780 underline, overline, and strike-through.
11781 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
11782 ns_draw_text_decoration. Change treatment of cursor drawing to
11783 accommodate underlining, etc.
11785 2011-07-28 Eli Zaretskii <eliz@gnu.org>
11787 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
11790 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
11792 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
11793 Without this fix, if a signal arrives just after memory fills up,
11794 'malloc' might be invoked reentrantly.
11796 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
11797 In other words, assume that every image size is allowed, on non-X
11798 hosts. This assumption is probably wrong, but it lets Emacs compile.
11800 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
11802 * regex.c (re_iswctype): Convert return values to boolean.
11804 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
11806 * xdisp.c (compute_display_string_pos): Don't use cached display
11807 string position if the buffer had its restriction changed.
11810 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
11812 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
11814 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
11816 Integer signedness and overflow and related fixes. (Bug#9079)
11818 * bidi.c: Integer size and overflow fixes.
11819 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
11820 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
11821 (bidi_cache_find_level_change, bidi_cache_ensure_space)
11822 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
11823 (bidi_find_other_level_edge):
11824 Use ptrdiff_t instead of EMACS_INT where either will do.
11825 This works better on 32-bit hosts configured --with-wide-int.
11826 (bidi_cache_ensure_space): Check for size-calculation overflow.
11827 Use % rather than repeated addition, for better worst-case speed.
11828 Don't set bidi_cache_size until after xrealloc returns, because it
11830 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
11831 (bidi_cache_ensure_space): Also check that the bidi cache size
11832 does not exceed that of the largest Lisp string or buffer. See Eli
11833 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
11835 * alloc.c (__malloc_size_t): Remove.
11836 All uses replaced by size_t. See Andreas Schwab's note
11837 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
11839 * image.c: Improve checking for integer overflow.
11840 (check_image_size): Assume that f is nonnull, since
11841 it is always nonnull in practice. This is one less thing to
11842 worry about when checking for integer overflow later.
11843 (x_check_image_size): New function, which checks for integer
11844 overflow issues inside X.
11845 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
11846 This removes the need for a memory_full check.
11847 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
11848 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
11849 (xbm_read_bitmap_data): Change locals back to 'int', since
11850 their values must fit in 'int'.
11851 (xpm_load_image, png_load, tiff_load):
11852 Invoke x_create_x_image_and_pixmap earlier,
11853 to avoid much needless work if the image is too large.
11854 (tiff_load): Treat overly large images as if
11855 x_create_x_image_and_pixmap failed, not as malloc failures.
11856 (gs_load): Use x_check_image_size.
11858 * gtkutil.c: Omit integer casts.
11859 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
11860 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
11862 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
11864 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
11865 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
11866 would wrongly return t on a 64-bit host.
11868 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
11869 The plain *_OVERFLOW macros run afoul of GCC bug 49705
11870 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
11871 and therefore cause GCC to emit a bogus diagnostic in some cases.
11873 * image.c: Integer signedness and overflow and related fixes.
11874 This is not an exhaustive set of fixes, but it's time to
11875 record what I've got.
11876 (lookup_pixel_color, check_image_size): Remove redundant decls.
11877 (check_image_size): Don't assume that arbitrary EMACS_INT values
11878 fit in 'int', or that arbitrary 'double' values fit in 'int'.
11879 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
11880 (tiff_load, imagemagick_load_image):
11881 Check for overflow in size calculations.
11882 (x_create_x_image_and_pixmap): Remove unnecessary test for
11883 xmalloc returning NULL; that can't happen.
11884 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
11885 (xpm_color_bucket): Use better integer hashing function.
11886 (xpm_cache_color): Don't possibly over-allocate memory.
11887 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
11888 (gif_memory_source):
11889 Use ptrdiff_t, not int or size_t, to record sizes.
11890 (png_load): Don't assume values greater than 2**31 fit in 'int'.
11891 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
11892 either works, as we prefer signed integers.
11893 (tiff_read_from_memory, tiff_write_from_memory):
11894 Return tsize_t, not size_t, since that's what the TIFF API wants.
11895 (tiff_read_from_memory): Don't fail simply because the read would
11896 go past EOF; instead, return a short read.
11897 (tiff_load): Omit no-longer-needed casts.
11898 (Fimagemagick_types): Don't assume size fits into 'int'.
11900 Improve hashing quality when configured --with-wide-int.
11901 * fns.c (hash_string): New function, taken from sxhash_string.
11902 Do not discard information about ASCII character case; this
11903 discarding is no longer needed.
11904 (sxhash-string): Use it. Change sig to match it. Caller changed.
11905 * lisp.h: Declare it.
11906 * lread.c (hash_string): Remove, since we now use fns.c's version.
11907 The fns.c version returns a wider integer if --with-wide-int is
11908 specified, so this should help the quality of the hashing a bit.
11910 * emacs.c: Integer overflow minor fix.
11911 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
11912 Define only if GNU_LINUX.
11913 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
11915 * dispnew.c: Integer signedness and overflow fixes.
11916 Remove unnecessary forward decls, that were a maintenance hassle.
11917 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
11919 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
11920 (scrolling_window): Use ptrdiff_t, not int, for byte count.
11921 (prepare_desired_row, line_draw_cost):
11922 Use int, not unsigned, where either works.
11923 (save_current_matrix, restore_current_matrix):
11924 Use ptrdiff_t, not size_t, where either works.
11925 (init_display): Check for overflow more accurately, and without
11926 relying on undefined behavior.
11928 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
11929 Remove, replacing with the new symbols in lisp.h. All uses changed.
11930 * fileio.c (make_temp_name):
11931 * filelock.c (lock_file_1, lock_file):
11932 * xdisp.c (message_dolog):
11933 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
11934 Use pMd etc. instead.
11935 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
11936 replacing the pWIDE etc. symbols removed from editfns.c.
11938 * keyboard.h (num_input_events): Now uintmax_t.
11939 This is (very slightly) less likely to mess up due to wraparound.
11942 * buffer.c: Integer signedness fixes.
11943 (alloc_buffer_text, enlarge_buffer_text):
11944 Use ptrdiff_t rather than size_t when either will do, as we prefer
11947 * alloc.c: Integer signedness and overflow fixes.
11948 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
11949 (__malloc_size_t): Default to size_t, not to int.
11950 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
11951 (Fgarbage_collect, mark_object_loop_halt, mark_object):
11952 Prefer ptrdiff_t to size_t when either would do, as we prefer
11954 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
11955 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
11956 Now const. Initialize with values that are in range even if char
11958 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
11959 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
11960 These functions do the right thing with sizes > 2**32.
11961 (check_depth): Now ptrdiff_t, not int.
11962 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
11963 Adjust to new way of storing sizes. Check for size overflow bugs
11965 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
11966 slightly wrong anyway, as it missed one instance of
11967 XMALLOC_OVERRUN_CHECK_OVERHEAD.
11968 (refill_memory_reserve): Omit needless cast to size_t.
11969 (mark_object_loop_halt): Mark as externally visible.
11971 * xselect.c: Integer signedness and overflow fixes.
11972 (Fx_register_dnd_atom, x_handle_dnd_message):
11973 Use ptrdiff_t, not size_t, since we prefer signed.
11974 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
11975 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
11976 x_dnd_atoms_size and x_dnd_atoms_length.
11978 * doprnt.c: Prefer signed to unsigned when either works.
11980 * doprnt.c (doprnt):
11982 * xdisp.c (vmessage):
11983 Use ptrdiff_t, not size_t, when using or implementing doprnt,
11984 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
11985 prefer signed arithmetic to avoid comparison confusion.
11986 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
11987 but is a bit tricky.
11989 Assume freestanding C89 headers, string.h, stdlib.h.
11990 * data.c, doprnt.c, floatfns.c, print.c:
11991 Include float.h unconditionally.
11992 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
11993 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
11994 * regex.c: Likewise for stddef.h, string.h.
11995 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
11996 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
11997 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
11998 (STDC_HEADERS): Remove obsolete defines.
11999 * sysdep.c: Include limits.h unconditionally.
12001 Assume support for memcmp, memcpy, memmove, memset.
12002 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
12003 * regex.c (memcmp, memcpy):
12004 Remove; we assume C89 now.
12006 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
12007 (__malloc_safe_bcopy): Remove; no longer needed.
12009 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
12010 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
12011 well either way, and we prefer signed to unsigned.
12013 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
12015 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
12016 closes the connection while we're reading (bug#9182).
12018 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
12020 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
12021 are specified (Bug#9168).
12023 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
12025 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
12026 Found by GCC static checking and --with-wide-int on a 32-bit host.
12028 2011-07-25 Eli Zaretskii <eliz@gnu.org>
12030 * xdisp.c (compute_display_string_pos): Fix logic of caching
12031 previous display string position. Initialize cached_prev_pos to
12032 -1. Fixes slow-down at the beginning of a buffer.
12034 2011-07-24 Eli Zaretskii <eliz@gnu.org>
12036 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
12037 for attrs[LFACE_FONTSET_INDEX].
12039 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
12041 * xml.c (parse_region): Remove unused local
12042 that was recently introduced.
12044 2011-07-23 Eli Zaretskii <eliz@gnu.org>
12046 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
12047 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
12049 * xdisp.c (move_it_in_display_line_to): Record the best matching
12050 position for TO_CHARPOS while scanning the line, and restore it on
12051 exit if none of the characters scanned was an exact match.
12052 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
12053 when exact match is impossible due to invisible text, and the
12054 lines are truncated.
12056 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
12058 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
12061 2011-07-22 Eli Zaretskii <eliz@gnu.org>
12063 Fix a significant slow-down of cursor motion with C-n, C-p,
12064 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
12065 auto-repeat under bidi redisplay in fontified buffers.
12066 * xdisp.c (compute_stop_pos_backwards): New function.
12067 (next_element_from_buffer): Call compute_stop_pos_backwards to
12068 find a suitable prev_stop when we find ourselves before
12070 (reseat): Don't look for prev_stop, as that could mean a very long
12072 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
12073 <cached_disp_overlay_modiff>: Cache for last found display string
12075 (compute_display_string_pos): Return the cached position if asked
12076 about the same buffer in the same area of character positions, and
12077 the buffer wasn't changed since the time the display string
12078 position was cached.
12080 2011-07-22 Eli Zaretskii <eliz@gnu.org>
12082 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
12083 is an integer, which is important for empty lines. (Bug#9149)
12085 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
12087 * frame.c (Fmodify_frame_parameters): In tty case, update the
12088 default face if necessary (Bug#4238).
12090 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
12092 * editfns.c (Fstring_to_char): No need to explain what a character
12093 is in the docstring (Bug#6576).
12095 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
12097 * xml.c (parse_region): Make sure we always return a tree.
12099 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
12101 * xml.c (parse_region): If a document contains only comments,
12104 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
12106 * xml.c (make_dom): Return comments, too.
12108 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
12111 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
12112 and the surrounding thread.
12113 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
12114 rather than fgets, and retry after EINTR. Otherwise, 'emacs
12115 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
12117 * s/openbsd.h (BROKEN_SIGIO): Define.
12118 * unexelf.c (unexec) [__OpenBSD__]:
12119 Don't update the .mdebug section of the Alpha COFF symbol table.
12121 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
12123 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
12126 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
12128 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
12129 This fixes some race conditions on the permissions of any newly
12132 * alloc.c (valid_pointer_p): Use pipe, not open.
12133 This fixes some permissions issues when debugging.
12135 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
12136 If fchown fails to set both uid and gid, try to set just gid,
12137 as that is sometimes allowed. Adjust the file's mode to eliminate
12138 setuid or setgid bits that are inappropriate if fchown fails.
12140 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
12142 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ

12148 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
12150 * lread.c (read_integer): Unread even EOF character.
12151 (read1): Likewise. Properly record start position of symbol.

12154 symbol character follows.
12156 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
12158 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
12159 This works around a problem with the previous change to Fcopy_file.
12160 Recent glibc declares fchown with __attribute__((warn_unused_result)),
12161 and without this change, GCC might complain about discarding
12162 fchown's return value.
12164 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
12166 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
12168 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
12170 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
12172 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
12174 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
12175 it's used from the C level.
12177 * process.c: Use the same condition for POLL_FOR_INPUT in both
12178 keyboard.c and process.c (bug#1858).
12180 2011-07-09 Lawrence Mitchell <wence@gmx.li>
12182 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
12183 (Fgnutls_boot): Use it.
12185 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
12187 * doc.c (Fsubstitute_command_keys): Revert last change.
12189 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
12191 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
12192 quotes the next character, and doesn't affect other longer
12193 sequences (bug#8935).
12195 * lread.c (syms_of_lread): Clarify that is isn't only
12196 `eval-buffer' and `eval-defun' that's affected by
12197 `lexical-binding' (bug#8460).
12199 2011-07-15 Eli Zaretskii <eliz@gnu.org>
12201 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
12202 bidi redisplay when a line includes both an image and is truncated.
12204 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
12206 Fix minor problems found by static checking.
12207 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
12208 (elsz): Now a signed constant, not a size_t var. We prefer signed
12209 types to unsigned, to avoid integer comparison confusion. Without
12210 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
12211 "cannot optimize loop, the loop counter may overflow", a symptom
12213 * indent.c (Fvertical_motion): Mark locals as initialized.
12214 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
12216 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>

12242 (display_string): If we need to ignore text properties of
12243 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
12244 original value of -1 will not work with bidi.)
12245 (compute_display_string_pos): First arg is now struct
12246 `text_pos *'; all callers changed. Support display properties on
12248 (compute_display_string_end): Support display properties on Lisp
12250 (init_iterator, reseat_1, reseat_to_string): Initialize the
12251 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
12252 when iterating on a string not from display properties).
12253 (compute_display_string_pos, compute_display_string_end):
12254 Fix calculation of the object to scan. Fixes an error when using
12256 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
12257 base_level_stop; instead, set base_level_stop to BEGV.
12258 Fixes crashes in vertical-motion.
12259 (next_element_from_buffer): Improve commentary for when
12260 the iterator is before prev_stop.
12261 (init_iterator): Initialize bidi_p from the default value of

12284 parts of next_element_from_buffer, next_element_from_string, and
12285 next_element_from_c_string.
12286 (tool_bar_lines_needed, redisplay_tool_bar)
12287 (display_menu_bar): Force left-to-right direction. Add a FIXME

12302 pushed the iterator stack, restore the internal state of the bidi
12303 iterator by calling bidi_pop_it same number of times.
12304 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
12305 and we are bidi-iterating, don't decrement the iterator position;
12306 instead, set the first_elt flag in the bidi iterator, to produce
12308 (reseat_1): Remove redundant setting of string_from_display_prop_p.
12309 (push_display_prop): xassert that we are iterating a buffer.
12310 (push_it, pop_it): Save and restore paragraph_embedding member.
12311 (handle_single_display_spec, next_overlay_string)

12313 (push_display_prop): Set up the `unibyte' member of bidi_it.string
12314 correctly. Don't assume unibyte strings are not bidi-reordered.

12323 property. Fix a typo in popping stretch info. Add an assertion
12324 for verifying that the iterator position is in sync with the bidi
12326 (handle_single_display_spec, get_overlay_strings_1)

12416 (struct iterator_stack_entry): New members bidi_p,
12417 paragraph_embedding, and from_disp_prop_p.

12471 The old code sometimes used this field without initializing it.
12473 * alloc.c (gc_sweep): Don't read past end of array.

12738 (clone_per_buffer_values): Don't assume that

12740 This isn't true in general, and it's particularly not true
12741 if Emacs is configured with --with-wide-int.
12742 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
12743 New macros, used in the buffer.c change.

12779 Random fixes. E.g., (random) never returned negative values.
12780 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
12781 subseconds part to the entropy, as that's a bit more random.
12782 Prefer signed to unsigned, since the signedness doesn't matter and
12783 in general we prefer signed. When given a limit, use a
12784 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
12785 latter isn't right if USE_2_TAGS_FOR_INTS.
12786 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
12787 not 0..VALMASK. Don't discard "excess" bits that random () returns.

12799 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
12800 This is more efficient than Ffile_directory_p and avoids a minor race.
12802 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
12804 * buffer.c (Foverlay_put): Say what the return value is
12807 * fileio.c (barf_or_query_if_file_exists): Check first if the file
12808 is a directory before asking whether to use the file name
12810 (barf_or_query_if_file_exists): Make the "File is a directory"
12811 error be more correct.
12813 * fns.c (Frequire): Remove the mention of the .gz files, since
12814 that's installation-specific, but keep the mention of
12815 `get-load-suffixes'.

12819 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

12827 Qgnutls_bootprop_verify_error (which is no longer used).
12829 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
12830 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
12831 Also (re)move comments that are misplaced or no longer relevant.

12858 2011-07-02 Lars Magne Ingebrigtsen <larsi@gnus.org>
12860 * lread.c (syms_of_lread): Mention single symbols defined by
12861 `defvar' or `defconst' (bug#7154).
12863 * fns.c (Frequire): Mention .el.gz files (bug#7314).

12894 (syms_of_keymap): Defsubr make-composed-keymap.
12895 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

12932 * eval.c (struct backtrace): Simplify and port the data structure.
12933 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
12934 signed bit field, as this assumption is not portable and it makes
12935 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
12936 "char debug_on_exit : 1" as this is not portable either; instead,
12937 use the portable "unsigned int debug_on_exit : 1". Remove unused
12938 member evalargs. Remove obsolete comments about cc bombing out.
12940 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

13034 Use gnulib's dup2 module instead of rolling our own.
13035 * sysdep.c (dup2) [!HAVE_DUP2]: Remove; gnulib now does this.

13106 * print.c (printchar, strout): Check for string overflow.
13107 (PRINTPREPARE, printchar, strout):
13108 Don't set size unless allocation succeeds.
13110 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
13111 for sizes. Check for string overflow more accurately.
13112 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
13114 * macros.c: Integer and buffer overflow fixes.
13115 * keyboard.h (struct keyboard.kbd_macro_bufsize):
13116 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

13120 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
13122 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
13124 * lread.c: Integer overflow fixes.
13125 (read_integer): Radix is now EMACS_INT, not int,
13126 to improve quality of diagnostics for out-of-range radices.
13127 Calculate buffer size correctly for out-of-range radices.
13128 (read1): Check for integer overflow in radices, and in
13129 read-circle numbers.
13130 (read_escape): Avoid int overflow.
13131 (Fload, openp, read_buffer_size, read1)
13132 (substitute_object_recurse, read_vector, read_list, map_obarray):

13148 2011-06-22 Leo Liu <sdl.web@gmail.com>
13150 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
13151 Move to minibuffer.el.
13153 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
13155 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
13156 The following patches are for when GLYPH_DEBUG && !XASSERT.
13157 * dispextern.h (trace_redisplay_p, dump_glyph_string):
13158 * dispnew.c (flush_stdout):
13159 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
13160 Mark as externally visible.
13161 * dispnew.c (check_window_matrix_pointers): Now static.
13162 * dispnew.c (window_to_frame_vpos):
13163 * xfns.c (unwind_create_frame):
13164 * xterm.c (x_check_font): Remove unused local.
13165 * scroll.c (CHECK_BOUNDS):
13166 * xfaces.c (cache_fache): Rename local to avoid shadowing.
13167 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
13168 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
13169 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
13170 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
13172 (debug_method_add): Use va_list and vsprintf rather than relying
13173 on undefined behavior with wrong number of arguments.
13174 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
13175 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
13176 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
13177 since we're not interested in debugging glyphs with old libraries.
13178 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
13179 GCC 4.6.0's static checking.
13181 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>

13199 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
13200 (.bitmaps_last, struct x_output.icon_bitmap):
13201 Use ptrdiff_t, not int, for bitmap indexes.
13202 (x_allocate_bitmap_record): Check for size overflow.
13203 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
13205 Use ptrdiff_t, not int, for overlay counts.
13206 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
13207 * editfns.c (overlays_around, get_pos_property):

13209 * xdisp.c (next_overlay_change, note_mouse_highlight):
13210 * xfaces.c (face_at_buffer_position):
13211 * buffer.c (OVERLAY_COUNT_MAX): New macro.
13212 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
13213 (Fnext_overlay_change, Fprevious_overlay_change)
13214 (mouse_face_overlay_overlaps, Foverlays_in):
13215 Use ptrdiff_t, not int, for sizes.
13216 (overlays_at, overlays_in): Check for size-calculation overflow.
13218 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
13220 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
13221 (x_session_initialize): Do not assume string length fits in int.
13223 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
13224 This is unlikely, but can occur if DPI is outlandish.
13226 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
13227 * xselect.c (Fx_get_atom_name): Avoid need for strlen.

13230 * xrdb.c (magic_file_p, search_magic_path):
13231 Omit last arg SUFFIX; it was always 0. All callers changed.
13232 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
13234 * xfont.c (xfont_match): Avoid need for strlen.
13236 * xfns.c: Don't assume strlen fits in int.

13239 * xdisp.c (message_log_check_duplicate): Return intmax_t,
13240 not unsigned long, as we prefer signed integers. All callers changed.
13241 Detect integer overflow in repeat count.
13242 (message_dolog): Don't assume print length fits in 39 bytes.
13243 (display_mode_element): Don't assume strlen fits in int.
13245 * termcap.c: Don't assume sizes fit in int and never overflow.
13246 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.

13264 * filelock.c: Fix some buffer overrun and integer overflow issues.
13265 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
13266 Reformulate so as not to need the command string.
13267 Invoke gzip -cd rather than gunzip, as it's more portable.
13268 (lock_info_type, lock_file_1, lock_file):
13269 Don't assume pid_t and time_t fit in unsigned long.
13270 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
13271 (current_lock_owner): Prefer signed type for sizes.
13272 Use memcpy, not strncpy, where memcpy is what is really wanted.
13273 Don't assume (via atoi) that time_t and pid_t fit in int.
13274 Check for time_t and/or pid_t out of range, e.g., via a network share.
13275 Don't alloca where an auto var works fine.
13277 * fileio.c: Fix some integer overflow issues.
13278 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
13279 Don't assume string length fits in int.
13280 (directory_file_name): Don't assume string length fits in long.
13281 (make_temp_name): Don't assume pid fits in int, or that its print
13282 length is less than 20.

13302 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
13304 * lread.c (invalid_syntax): Omit length argument.
13305 All uses changed. This doesn't fix a bug, but it simplifies the
13306 code away from its former Hollerith-constant appearance, and it's
13307 one less 'int' to worry about when looking at integer-overflow issues.
13308 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
13310 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
13311 This didn't break anything, but it didn't help either.
13312 It's confusing to put a bogus integer in a place where the actual
13313 value does not matter.
13314 (LIST_END_P): Remove unused macro and its bogus comment.
13315 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
13317 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
13318 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
13320 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
13321 We prefer signed types, and the value cannot exceed the EMACS_INT
13322 range anyway (because otherwise the length would not be representable).
13323 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
13324 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
13325 This avoids a GCC warning when WIDE_EMACS_INT.
13327 * indent.c (sane_tab_width): New function.
13328 (current_column, scan_for_column, Findent_to, position_indentation)
13329 (compute_motion): Use it. This is just for clarity.
13330 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.

13336 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
13338 * editfns.c, insdel.c:
13339 Omit unnecessary forward decls, to simplify future changes.
13341 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
13343 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
13345 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
13346 Use much-faster test for byte-length change.
13347 Don't assume string byte-length fits in 'int'.
13348 Check that character arg fits in 'int'.
13349 (mapcar1): Declare byte as byte, for clarity.
13351 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
13353 * fns.c (concat): Catch string overflow earlier.
13354 Do not rely on integer wraparound.
13356 * dispextern.h (struct it.overlay_strings_charpos)
13357 (struct it.selective): Now EMACS_INT, not int.
13358 * xdisp.c (forward_to_next_line_start)
13359 (back_to_previous_visible_line_start)
13360 (reseat_at_next_visible_line_start, next_element_from_buffer):
13361 Don't arbitrarily truncate the value of 'selective' to int.
13363 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
13365 * composite.c: Don't truncate sizes to 'int'.
13366 (composition_gstring_p, composition_reseat_it)
13367 (composition_adjust_point): Use EMACS_INT, not int.
13368 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
13369 not EMACS_UINT, for indexes.
13371 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
13373 * buffer.c: Include <verify.h>.
13374 (struct sortvec.priority, struct sortstr.priority):
13375 Now EMACS_INT, not int.
13376 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
13377 (struct sortstr.size, record_overlay_string)
13378 (struct sortstrlist.size, struct sortlist.used):
13379 Don't truncate size to int.
13380 (record_overlay_string): Check for size-calculation overflow.
13381 (init_buffer_once): Check at compile-time, not run-time.
13383 2011-06-22 Jim Meyering <meyering@redhat.com>
13385 Don't leak an XBM-image-sized buffer
13386 * image.c (xbm_load): Free the image buffer after using it.
13388 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
13391 * composite.c (find_automatic_composition): Omit needless 'return 0;'
13392 that Sun C diagnosed.
13393 * fns.c (secure_hash): Fix pointer signedness issue.
13394 * intervals.c (static_offset_intervals): New function.
13395 (offset_intervals): Use it.
13397 2011-06-21 Leo Liu <sdl.web@gmail.com>
13400 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
13403 * fns.c (secure_hash): Rename from crypto_hash_function and change
13404 the first arg to accept symbols.
13405 (Fsecure_hash): New primitive.
13406 (syms_of_fns): New symbols.
13408 2011-06-20 Deniz Dogan <deniz@dogan.se>
13410 * process.c (Fset_process_buffer): Clarify return value in

13424 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
13425 check till after the cache is created in init_frame_faces.
13427 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
13429 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
13431 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
13433 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
13434 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
13435 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
13437 Improve buffer-overflow checking (Bug#8873).
13438 * fileio.c (Finsert_file_contents):
13439 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
13440 Remove the old (too-loose) buffer overflow checks.
13441 They weren't needed, since make_gap checks for buffer overflow.
13442 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
13443 The old code merely checked for Emacs fixnum overflow, and relied
13444 on undefined (wraparound) behavior. The new code avoids undefined
13445 behavior, and also checks for ptrdiff_t and/or size_t overflow.
13447 * editfns.c (Finsert_char): Don't dump core with very negative counts.
13448 Tune. Don't use wider integers than needed. Don't use alloca.
13449 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
13451 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
13453 * insdel.c, lisp.h (buffer_overflow): New function.
13454 (insert_from_buffer_1, replace_range, replace_range_2):
13455 * insdel.c (make_gap_larger):
13456 * editfns.c (Finsert_char):
13457 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
13459 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
13461 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
13463 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
13465 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
13466 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
13468 * fileio.c: Don't assume EMACS_INT fits in off_t.
13469 (emacs_lseek): New static function.
13470 (Finsert_file_contents, Fwrite_region): Use it.
13471 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
13473 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
13475 * fns.c: Don't overflow int when computing a list length.
13476 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
13477 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
13478 truncation on 64-bit hosts. Check for QUIT every
13479 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
13480 faster and is responsive enough.
13481 (Flength): Report an error instead of overflowing an integer.
13482 (Fsafe_length): Return a float if the value is not representable
13483 as a fixnum. This shouldn't happen except in contrived situations.
13484 (Fnthcdr, Fsort): Don't assume list length fits in int.
13485 (Fcopy_sequence): Don't assume vector length fits in int.
13487 * alloc.c: Check that resized vectors' lengths fit in fixnums.
13488 (header_size, word_size): New constants.
13489 (allocate_vectorlike): Don't check size overflow here.
13490 (allocate_vector): Check it here instead, since this is the only
13491 caller of allocate_vectorlike that could cause overflow.
13492 Check that the new vector's length is representable as a fixnum.
13494 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
13495 The previous code was bogus. For example, next_almost_prime (32)
13496 returned 39, which is undesirable as it is a multiple of 3; and
13497 next_almost_prime (24) returned 25, which is a multiple of 5 so
13498 why was the code bothering to check for multiples of 7?
13500 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
13502 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
13504 Variadic C functions now count arguments with ptrdiff_t.
13505 This partly undoes my 2011-03-30 change, which replaced int with size_t.
13506 Back then I didn't know that the Emacs coding style prefers signed int.
13507 Also, in the meantime I found a few more instances where arguments
13508 were being counted with int, which may truncate counts on 64-bit
13509 machines, or EMACS_INT, which may be unnecessarily wide.
13510 * lisp.h (struct Lisp_Subr.function.aMANY)
13511 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
13512 Arg counts are now ptrdiff_t, not size_t.
13513 All variadic functions and their callers changed accordingly.
13514 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
13515 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
13516 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
13517 * callint.c (Fcall_interactively): Check arg count for overflow,
13518 to avoid potential buffer overrun. Use signed char, not 'int',
13519 for 'varies' array, so that we needn't bother to check its size
13520 calculation for overflow.
13521 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
13522 * eval.c (apply_lambda):
13523 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
13524 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
13525 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
13527 * callint.c (Fcall_interactively): Don't use index var as event count.
13529 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
13530 * mem-limits.h (SIZE): Remove; no longer used.
13532 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
13534 Remove unnecessary casts.
13535 * xterm.c (x_term_init):
13536 * xfns.c (x_set_border_pixel):
13537 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
13538 These aren't needed now that we assume ANSI C.
13540 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
13541 It's more likely to cause problems (due to unsigned overflow)
13544 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
13546 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
13548 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
13550 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
13552 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
13554 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
13556 GLYPH_CODE_FACE returns EMACS_INT, not int.
13557 * dispextern.h (merge_faces):
13558 * xfaces.c (merge_faces):
13559 * xdisp.c (get_next_display_element, next_element_from_display_vector):
13560 Don't assume EMACS_INT fits in int.
13562 * character.h (CHAR_VALID_P): Remove unused parameter.
13563 * fontset.c, lisp.h, xdisp.c: All uses changed.
13565 * editfns.c (Ftranslate_region_internal): Omit redundant test.
13567 * fns.c (concat): Minor tuning based on overflow analysis.
13568 This doesn't fix any bugs. Use int to hold character, instead
13569 of constantly refetching from Emacs object. Use XFASTINT, not
13570 XINT, for value known to be a character. Don't bother comparing
13571 a single byte to 0400, as it's always less.
13573 * floatfns.c (Fexpt):
13574 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
13576 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
13579 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
13581 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
13582 Without this fix, on a 64-bit host (aset S 0 4294967386) would
13583 incorrectly succeed when S was a string, because 4294967386 was
13584 truncated before it was used.
13586 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
13587 Otherwise, an out-of-range integer could cause undefined behavior
13590 * composite.c: Use int, not EMACS_INT, for characters.
13591 (fill_gstring_body, composition_compute_stop_pos): Use int, not
13592 EMACS_INT, for values that are known to be in character range.
13593 This doesn't fix any bugs but is the usual style inside Emacs and
13594 may generate better code on 32-bit machines.
13596 Make sure a 64-bit char is never passed to ENCODE_CHAR.
13597 This is for reasons similar to the recent CHAR_STRING fix.
13598 * charset.c (Fencode_char): Check that character arg is actually
13599 a character. Pass an int to ENCODE_CHAR.
13600 * charset.h (ENCODE_CHAR): Verify that the character argument is no
13601 wider than 'int', as a compile-time check to prevent future regressions
13604 * character.c (char_string): Remove unnecessary casts.
13606 Make sure a 64-bit char is never passed to CHAR_STRING.
13607 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
13608 by silently ignoring the top 32 bits, allowing some values
13609 that were far too large to be valid characters.
13610 * character.h: Include <verify.h>.
13611 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
13612 arguments are no wider than unsigned, as a compile-time check
13613 to prevent future regressions in this area.
13615 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
13616 (Fsubst_char_in_region):
13618 * xdisp.c (decode_mode_spec_coding):
13619 Adjust to CHAR_STRING's new requirement.
13620 * editfns.c (Finsert_char, Fsubst_char_in_region):
13621 * fns.c (concat): Check that character args are actually
13622 characters. Without this test, these functions did the wrong
13623 thing with wildly out-of-range values on 64-bit hosts.
13625 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
13626 These casts should not be needed on 32-bit hosts, either.
13627 * keyboard.c (read_char):
13628 * lread.c (Fload): Remove casts to unsigned.
13630 * lisp.h (UNSIGNED_CMP): New macro.
13631 This fixes comparison bugs on 64-bit hosts.
13632 (ASCII_CHAR_P): Use it.
13633 * casefiddle.c (casify_object):
13634 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
13635 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
13636 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
13637 * dispextern.h (FACE_FROM_ID):
13638 * keyboard.c (read_char): Use UNSIGNED_CMP.
13640 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
13641 not to EMACS_INT, to avoid GCC warning.
13643 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
13645 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
13646 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
13647 isn't needed on 32-bit machines.
13649 * buffer.c (Fgenerate_new_buffer_name):
13650 Use EMACS_INT for count, not int.
13651 (advance_to_char_boundary): Return EMACS_INT, not int.
13653 * data.c (Qcompiled_function): Now static.
13655 * window.c (window_body_lines): Now static.
13657 * image.c (gif_load): Rename local to avoid shadowing.
13659 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
13660 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
13661 * alloc.c (make_save_value): Integer argument is now of type
13662 ptrdiff_t, not int.
13663 (mark_object): Use ptrdiff_t, not int.
13664 * lisp.h (pD): New macro.
13665 * print.c (print_object): Use it.
13667 * alloc.c: Use EMACS_INT, not int, to count objects.
13668 (total_conses, total_markers, total_symbols, total_vector_size)
13669 (total_free_conses, total_free_markers, total_free_symbols)
13670 (total_free_floats, total_floats, total_free_intervals)
13671 (total_intervals, total_strings, total_free_strings):
13672 Now EMACS_INT, not int. All uses changed.
13673 (Fgarbage_collect): Compute overall total using a double, so that
13674 integer overflow is less likely to be a problem. Check for overflow
13675 when converting back to an integer.
13676 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
13677 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
13678 These were 'int' variables that could overflow on 64-bit hosts;
13679 they were never used, so remove them instead of repairing them.
13680 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
13681 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
13682 Previously, this ceilinged at INT_MAX, but that doesn't work on
13684 (allocate_pseudovector): Don't use EMACS_INT when int would do.
13686 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
13687 (allocate_vectorlike): Check for ptrdiff_t overflow.
13688 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
13689 when a (possibly-narrower) signed value would do just as well.
13690 We prefer using signed arithmetic, to avoid comparison confusion.
13692 * alloc.c: Catch some string size overflows that we were missing.
13693 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
13694 for convenience in STRING_BYTES_MAX.
13695 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
13696 The definition here is exact; the one in lisp.h was approximate.
13697 (allocate_string_data): Check for string overflow. This catches
13698 some instances we weren't catching before. Also, it catches
13699 size_t overflow on (unusual) hosts where SIZE_MAX <= min
13700 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
13701 and ptrdiff_t and EMACS_INT are both 64 bits.
13703 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
13704 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
13705 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
13707 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
13709 * alloc.c (Fmake_string): Check for out-of-range init.
13711 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
13713 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
13715 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
13717 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
13718 xg_get_default_scrollbar_width.
13720 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
13721 (int_gtk_range_get_value): Move to the scroll bar part of the file.
13722 (style_changed_cb): Call update_theme_scrollbar_width and call
13723 x_set_scroll_bar_default_width and xg_frame_set_char_size for
13724 all frames (Bug#8505).
13725 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
13726 Call gtk_window_set_resizable if HAVE_GTK3.
13727 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
13728 and height if HAVE_GTK3 (Bug#8505).
13729 (scroll_bar_width_for_theme): New variable.
13730 (update_theme_scrollbar_width): New function.
13731 (xg_get_default_scrollbar_width): Move code to
13732 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
13733 (xg_initialize): Call update_theme_scrollbar_width.
13735 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
13737 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
13739 2011-06-12 Martin Rudalics <rudalics@gmx.at>
13741 * frame.c (make_frame): Call other_buffer_safely instead of
13744 * window.c (temp_output_buffer_show): Call display_buffer with
13745 second argument Vtemp_buffer_show_specifiers and reset latter
13746 immediately after the call.
13747 (Vtemp_buffer_show_specifiers): New variable.
13748 (auto_window_vscroll_p, next_screen_context_lines)
13749 (Vscroll_preserve_screen_position): Remove leading asterisks from
13752 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
13754 Fix minor problems found by GCC 4.6.0 static checking.
13755 * buffer.c (Qclone_number): Remove for now, as it's unused.
13756 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
13757 (record_buffer): Remove unused local.
13758 * frame.c (other_visible_frames, frame_buffer_list): Now static.
13759 (set_frame_buffer_list): Remove; unused.
13760 * frame.h (other_visible_frames): Remove decl.
13761 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
13762 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
13763 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
13765 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
13766 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
13767 Define only if HAVE_GPM.
13768 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
13769 (update_hints_inhibit): Remove; never set. All uses removed.
13770 * widgetprv.h (emacsFrameClassRec): Remove decl.
13771 * window.c (delete_deletable_window): Now returns void, since it
13772 wasn't returning anything.
13773 (compare_window_configurations): Remove unused locals.
13774 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
13775 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
13776 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
13777 the same widths as pointers. This follows up on the 2011-05-06 patch.
13778 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
13779 * xterm.h: Likewise.
13780 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.
13782 2011-06-12 Juanma Barranquero <lekktu@gmail.com>
13784 * makefile.w32-in: Update dependencies.
13785 (LISP_H): Add lib/intprops.h.
13787 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
13789 * image.c (gif_load): Add animation frame delay to the metadata.
13790 (syms_of_image): Use DEFSYM. New symbol `delay'.
13792 2011-06-11 Martin Rudalics <rudalics@gmx.at>
13794 * window.c (delete_deletable_window): Re-add.
13795 (Fset_window_configuration): Rewrite to handle dead buffers and
13796 consequently deletable windows.
13797 (window_tree, Fwindow_tree): Remove. Supply functionality in
13799 (compare_window_configurations): Simplify code.
13801 2011-06-11 Andreas Schwab <schwab@linux-m68k.org>
13803 * image.c (imagemagick_load_image): Fix type mismatch.
13804 (Fimagemagick_types): Likewise.
13806 * window.h (replace_buffer_in_windows): Declare.
13808 2011-06-11 Martin Rudalics <rudalics@gmx.at>
13810 * buffer.c: New Lisp objects Qbuffer_list_update_hook and
13811 Qclone_number. Remove external declaration of Qdelete_window.
13812 (Fbuffer_list): Rewrite doc-string. Minor restructuring of
13814 (Fget_buffer_create, Fmake_indirect_buffer, Frename_buffer):
13815 Run Qbuffer_list_update_hook if allowed.
13816 (Fother_buffer): Rewrite doc-string. Major rewrite for new
13817 buffer list implementation.
13818 (other_buffer_safely): New function.
13819 (Fkill_buffer): Replace call to replace_buffer_in_all_windows by
13820 calls to replace_buffer_in_windows and
13821 replace_buffer_in_windows_safely. Run Qbuffer_list_update_hook
13823 (record_buffer): Inhibit quitting and rewrite using quittable
13824 functions. Run Qbuffer_list_update_hook if allowed.
13825 (Frecord_buffer, Funrecord_buffer): New functions.
13826 (switch_to_buffer_1, Fswitch_to_buffer): Remove.
13827 Move switch-to-buffer to window.el.
13828 (bury-buffer): Move to window.el.
13829 (Vbuffer_list_update_hook): New variable.
13831 * lisp.h (other_buffer_safely): Add prototype in buffer.c
13834 * window.h (resize_frame_windows): Move up in code.
13835 (Fwindow_frame): Remove EXFUN.
13836 (replace_buffer_in_all_windows): Remove prototype.
13837 (replace_buffer_in_windows_safely): Add prototype.
13839 * window.c: Declare Qdelete_window static again. Move down
13840 declaration of select_count.
13841 (Fnext_window, Fprevious_window): Rewrite doc-strings.
13842 (Fother_window): Move to window.el.
13843 (window_loop): Remove DELETE_BUFFER_WINDOWS and UNSHOW_BUFFER
13844 cases. Add REPLACE_BUFFER_IN_WINDOWS_SAFELY case.
13845 (Fdelete_windows_on, Freplace_buffer_in_windows): Move to
13847 (replace_buffer_in_windows): Implement by calling
13848 Qreplace_buffer_in_windows.
13849 (replace_buffer_in_all_windows): Remove with some functionality
13850 moved into replace_buffer_in_windows_safely.
13851 (replace_buffer_in_windows_safely): New function.
13852 (select_window_norecord, select_frame_norecord): Move in front
13853 of run_window_configuration_change_hook. Remove now obsolete
13855 (Fset_window_buffer): Rewrite doc-string.

14302 Accept 3 additional arguments needed by handle_display_spec.
14303 This fixes incorrect cursor motion across display property with complex
14304 values: lists, `(when COND...)' forms, etc.
14305 (single_display_spec_string_p): Support property values that are
14306 lists with the argument STRING its top-level element.
14307 (display_prop_string_p): Fix the condition for processing a
14308 property that is a list to be consistent with handle_display_spec.
14309 (handle_display_spec): New function, refactored from the
14310 last portion of handle_display_prop.
14311 (compute_display_string_pos): Accept additional argument
14312 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
14313 value of a `display' property is a "replacing spec".
14314 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
14315 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
14316 the display property, but just return a value indicating whether
14317 the display property will replace the characters it covers.
14318 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
14319 frame_window_p members of struct bidi_it.
14320 (compute_display_string_pos, compute_display_string_end):
14322 (push_it): Accept second argument POSITION, where pop_it should
14323 jump to continue iteration.
14324 (reseat_1): Initialize bidi_it.disp_pos.
14326 * keyboard.c (adjust_point_for_property): Adjust the call to
14327 display_prop_intangible_p to its new signature.
14329 * dispextern.h (struct bidi_it): New member frame_window_p.
14330 (bidi_init_it): Update prototypes.
14331 (display_prop_intangible_p): Update prototype.
14332 (compute_display_string_pos, compute_display_string_end):
14333 Declare prototypes.
14334 (struct bidi_it): New members nchars and disp_pos. ch_len is now
14337 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
14339 Malloc failure behavior now depends on size of allocation.
14340 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
14341 * lisp.h: Change signatures accordingly.
14342 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
14343 All callers changed. (Bug#8762)
14345 * gnutls.c: Use Emacs's memory allocators.
14346 Without this change, the gnutls library would invoke malloc etc.
14347 directly, which causes problems on non-SYNC_INPUT hosts, and which
14348 runs afoul of improving memory_full behavior. (Bug#8761)
14349 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
14350 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
14351 xfree instead of the default malloc, realloc, free.
14352 (Fgnutls_boot): No need to check for memory allocation failure,
14353 since xmalloc does that for us.
14355 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
14356 * category.c (hash_get_category_set):
14357 * ccl.c (ccl_driver):
14358 * charset.c (Fdefine_charset_internal):

14369 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
14370 (Fsxhash, Fgethash, Fputhash, Fmaphash):
14371 * image.c (make_image, search_image_cache, lookup_image)
14372 (xpm_put_color_table_h):
14373 * lisp.h (struct Lisp_Hash_Table):
14374 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
14375 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
14376 for hashes and hash indexes, instead of 'unsigned' and 'int'.
14377 * alloc.c (allocate_vectorlike):
14378 Check for overflow in vector size calculations.
14379 * ccl.c (ccl_driver):
14380 Check for overflow when converting EMACS_INT to int.
14381 * fns.c, image.c: Remove unnecessary static decls that would otherwise
14382 need to be updated by these changes.
14383 * fns.c (make_hash_table, maybe_resize_hash_table):
14384 Check for integer overflow with large hash tables.
14385 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
14386 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
14387 (SXHASH_REDUCE): New macro.
14388 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
14389 Use it instead of discarding useful hash info with large hash values.
14390 (sxhash_float): New function.
14391 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
14392 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
14393 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
14394 Rewrite to use FIXNUM_BITS, as this simplifies things.
14395 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
14396 Adjust signatures to match updated version of code.
14397 (consing_since_gc): Now EMACS_INT, since a single hash table can
14398 use more than INT_MAX bytes.
14400 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
14402 Make it possible to build with GCC-4.6+ -O2 -flto.
14404 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
14406 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
14408 * minibuf.c (get_minibuffer, read_minibuf_unwind):
14409 Call minibuffer-inactive-mode.
14411 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
14413 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
14414 Update dependencies.
14416 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
14418 * data.c (init_data): Remove code for UTS, this system is not
14421 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
14423 Don't force ./temacs to start in terminal mode.
14425 * frame.c (make_initial_frame): Initialize faces in all cases, not
14426 only when CANNOT_DUMP is defined.
14427 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
14429 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
14431 * dispnew.c (add_window_display_history): Use const for the string
14432 pointer. Remove declaration, not needed.
14434 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
14436 Use 'inline', not 'INLINE'.
14437 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
14438 * alloc.c, fontset.c (INLINE): Remove.
14439 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
14440 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
14441 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
14442 * gmalloc.c (register_heapinfo): Use inline unconditionally.
14443 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
14445 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
14447 Make it possible to run ./temacs.
14449 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
14450 syms_of_callproc does the same thing. Remove test for
14451 "initialized", do it in the caller.
14452 * emacs.c (main): Avoid calling set_initial_environment when dumping.
14454 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
14456 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
14457 (read_minibuf): Use get_minibuffer.
14458 (syms_of_minibuf): Use DEFSYM.
14459 (Qmetadata): New var.
14460 * data.c (Qbuffer): Don't make it static.
14461 (syms_of_data): Use DEFSYM.
14463 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
14465 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
14466 (CCL_CODE_MIN): New macro.
14468 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
14470 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
14472 * eval.c (Qdebug): Now static.
14473 * lisp.h (Qdebug): Remove decl. This reverts a part of the
14474 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
14475 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
14477 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
14479 * image.c: Various fixes to ImageMagick code comments.
14480 (Fimagemagick_types): Doc fix.
14482 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
14484 Minor fixes prompted by GCC 4.6.0 warnings.
14486 * xselect.c (converted_selections, conversion_fail_tag): Now static.
14488 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
14489 (x_clipboard_manager_save_all): Move extern decl to ...
14490 * xterm.h: ... here, so that it can be checked for consistency.
14492 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
14494 * xselect.c (x_clipboard_manager_save_frame)
14495 (x_clipboard_manager_save_all): New functions.
14496 (Fx_clipboard_manager_save): Lisp function deleted.
14498 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
14499 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
14501 * xterm.h: Update prototype.
14503 2011-05-28 William Xu <william.xwl@gmail.com>
14505 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
14506 exiting (Bug#8239).
14508 2011-05-28 Jim Meyering <meyering@redhat.com>
14510 Avoid a sign-extension bug in crypto_hash_function.
14511 * fns.c (to_uchar): Define.
14512 (crypto_hash_function): Use it to convert some newly-signed
14513 variables to unsigned, to avoid sign-extension bugs. For example,
14514 without this change, (md5 "truc") would evaluate to
14515 45723a2aff78ff4fff7fff1114760e62 rather than the expected
14516 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
14517 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
14519 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
14521 Integer overflow fixes.
14523 * dbusbind.c: Serial number integer overflow fixes.
14524 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
14525 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
14526 to hold a serial number that is too large for a fixnum.
14527 (Fdbus_method_return_internal, Fdbus_method_error_internal):
14528 Check for serial numbers out of range. Decode any serial number
14529 that was so large that it became a float. (Bug#8722)
14531 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
14532 (Fdbus_call_method, Fdbus_call_method_asynchronously):
14533 Use XFASTINT rather than XUINT when numbers are nonnegative.
14534 (xd_append_arg, Fdbus_method_return_internal):
14535 (Fdbus_method_error_internal): Likewise. Also, for unsigned
14536 arguments, check that Lisp number is nonnegative, rather than
14537 silently wrapping negative numbers around. (Bug#8722)
14538 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
14541 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
14543 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
14545 ccl: Add integer overflow checks.
14546 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
14547 (IN_INT_RANGE): New macros.
14548 (ccl_driver): Use them to check for integer overflow when
14549 decoding a CCL program. Many of the new checks are whether XINT (x)
14550 fits in int; it doesn't always, on 64-bit hosts. The new version
14551 doesn't catch all possible integer overflows, but it's an
14552 improvement. (Bug#8719)
14554 * alloc.c (make_event_array): Use XINT, not XUINT.
14555 There's no need for unsigned here.
14557 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
14558 This follows up to the 2011-05-06 change that substituted uintptr_t
14559 for EMACS_INT. This case wasn't caught back then.
14561 Rework Fformat to avoid integer overflow issues.
14562 * editfns.c: Include <float.h> unconditionally, as it's everywhere
14563 now (part of C89). Include <verify.h>.
14564 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
14565 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
14566 (Fformat): Avoid the prepass trying to compute sizes; it was only
14567 approximate and thus did not catch overflow reliably. Instead, walk
14568 through the format just once, formatting and computing sizes as we go,
14569 checking for integer overflow at every step, and allocating a larger
14570 buffer as needed. Keep track separately whether the format is
14571 multibyte. Keep only the most-recently calculated precision, rather
14572 than them all. Record whether each argument has been converted to
14573 string. Use EMACS_INT, not int, for byte and char and arg counts.
14574 Support field widths and precisions larger than INT_MAX. Avoid
14575 sprintf's undefined behavior with conversion specifications such as %#d
14576 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
14577 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
14578 formatting out-of-range floating point numbers with int
14579 formats. (Bug#8668)
14581 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
14583 * data.c: Avoid integer truncation in expressions involving floats.
14584 * data.c: Include <intprops.h>.
14585 (arith_driver): When there's an integer overflow in an expression
14586 involving floating point, convert the integers to floating point
14587 so that the resulting value does not suffer from catastrophic
14588 integer truncation. For example, on a 64-bit host (* 4
14589 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
14590 Do not rely on undefined behavior after integer overflow.
14592 merge count_size_as_multibyte, parse_str_to_multibyte
14593 * character.c, character.h (count_size_as_multibyte):
14594 Rename from parse_str_to_multibyte; all uses changed.
14595 Check for integer overflow.
14596 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
14597 since it's now a duplicate of the other. This is more of
14598 a character than a buffer op, so better that it's in character.c.
14599 * fns.c, print.c: Adjust to above changes.
14601 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
14603 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
14605 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
14607 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
14608 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
14609 (x_clipboard_manager_save): Now static.
14610 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
14612 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
14613 (crypto_hash_function): Now static.
14614 Fix pointer signedness problems. Avoid unnecessary initializations.
14616 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
14618 * termhooks.h (Vselection_alist): Make it terminal-local.
14620 * terminal.c (create_terminal): Initialize it.
14622 * xselect.c: Support for clipboard managers.
14623 (Vselection_alist): Move to termhooks.h as terminal-local var.
14624 (LOCAL_SELECTION): New macro.
14625 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
14626 (symbol_to_x_atom): Remove gratuitous arg.
14627 (x_handle_selection_request, lisp_data_to_selection_data)
14628 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
14629 (x_own_selection, x_get_local_selection, x_convert_selection):
14630 New arg, specifying work frame. Use terminal-local Vselection_alist.
14631 (some_frame_on_display): Delete unused function.
14632 (Fx_own_selection_internal, Fx_get_selection_internal)
14633 (Fx_disown_selection_internal, Fx_selection_owner_p)
14634 (Fx_selection_exists_p): New optional frame arg.
14635 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
14636 (x_handle_selection_clear): Don't treat other terminals with the
14637 same keyboard specially. Use the terminal-local Vselection_alist.
14638 (x_clear_frame_selections): Use Frun_hook_with_args.
14640 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
14642 * xterm.h: Add support for those atoms.
14644 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
14646 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
14647 (converted_selections, conversion_fail_tag): New global variables.
14648 (x_selection_request_lisp_error): Free the above.
14649 (x_get_local_selection): Remove unnecessary code.
14650 (x_reply_selection_request): Args changed; handle arbitrary array
14651 of converted selections stored in converted_selections.
14652 Separate the XChangeProperty and SelectionNotify steps.
14653 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
14654 (x_convert_selection): New function.
14655 (x_handle_selection_event): Simplify.
14656 (x_get_foreign_selection): Don't ignore incoming requests while
14657 waiting for an answer; this will fail when we implement
14658 SAVE_TARGETS, and seems unnecessary anyway.
14659 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
14660 (Vx_sent_selection_functions): Doc fix.
14662 2011-05-26 Leo Liu <sdl.web@gmail.com>
14664 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
14666 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14668 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
14670 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
14671 for fringe update if it has periodic bitmap.
14672 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
14673 and fringe_bitmap_periodic_p.
14675 * fringe.c (get_fringe_bitmap_data): New function.
14676 (draw_fringe_bitmap_1, update_window_fringes): Use it.
14677 (update_window_fringes): Record periodicity of fringe bitmap in glyph
14678 row. Mark glyph row for fringe update if periodicity changed.
14680 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
14681 for fringe update unless it has periodic bitmap.
14683 2011-05-25 Kenichi Handa <handa@m17n.org>
14685 * xdisp.c (get_next_display_element): Set correct it->face_id for
14686 a static composition.

14700 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
14701 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
14702 Remove macros that are defined and never used.
14703 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
14705 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
14707 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
14708 (Fx_get_selection_internal): Minor cleanup.
14709 (Fx_own_selection_internal): Rename arguments for consistency with
14712 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>

14733 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
14734 report_file_error introduced by the change from 2011-05-07.
14736 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
14738 * systime.h (Time): Define only if emacs is defined.
14739 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
14740 where the include path doesn't have X11/X.h by default. See
14741 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
14743 2011-05-20 Kenichi Handa <handa@m17n.org>
14745 * composite.c (find_automatic_composition): Fix previous change.
14747 2011-05-20 Glenn Morris <rgm@gnu.org>
14749 * lisp.mk: New file, split from Makefile.in.
14750 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
14751 (shortlisp): Remove.
14752 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
14754 2011-05-19 Glenn Morris <rgm@gnu.org>
14756 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
14757 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
14758 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
14759 (lisp): Set the order to that of loadup.el.
14760 (shortlisp): Make it a copy of $lisp.
14761 (SOME_MACHINE_LISP): Remove.
14762 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
14763 Use just $shortlisp, not $SOME_MACHINE_LISP too.
14765 2011-05-18 Kenichi Handa <handa@m17n.org>
14767 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
14768 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
14769 (find_automatic_composition): Mostly rewrite for efficiency.
14771 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
14773 * makefile.w32-in: Update dependencies.
14775 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
14777 * menu.c: Include limits.h (fixes the MS-Windows build broken by
14778 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
14780 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
14782 Fix some integer overflow issues, such as string length overflow.
14784 * insdel.c (count_size_as_multibyte): Check for string overflow.
14786 * character.c (lisp_string_width): Check for string overflow.
14787 Use EMACS_INT, not int, for string indexes and lengths; in
14788 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
14789 the resulting string length overflows an EMACS_INT; instead,
14790 report a string overflow if no precision given. When checking for
14791 precision exhaustion, use a check that cannot possibly have
14792 integer overflow. (Bug#8675)
14793 * character.h (lisp_string_width): Adjust to new signature.
14795 * alloc.c (string_overflow): New function.
14796 (Fmake_string): Use it. This doesn't change behavior, but saves
14797 a few bytes and will simplify future changes.
14798 * character.c (string_escape_byte8): Likewise.
14799 * lisp.h (string_overflow): New decl.
14801 Fixups, following up to the user-interface timestamp change.
14802 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
14803 for UI timestamps, instead of unsigned long.
14804 * msdos.c (mouse_get_pos): Likewise.
14805 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
14806 * w32gui.h (Time): Define by including "systime.h" rather than by
14807 declaring it ourselves. (Bug#8664)
14809 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
14810 * image.c (clear_image_cache): Likewise.
14812 * term.c (term_mouse_position): Don't assume time_t wraparound.
14814 Be more systematic about user-interface timestamps.
14815 Before, the code sometimes used 'Time', sometimes 'unsigned long',
14816 and sometimes 'EMACS_UINT', to represent these timestamps.
14817 This change causes it to use 'Time' uniformly, as that's what X uses.
14818 This makes the code easier to follow, and makes it easier to catch
14819 integer overflow bugs such as Bug#8664.
14820 * frame.c (Fmouse_position, Fmouse_pixel_position):
14821 Use Time, not unsigned long, for user-interface timestamps.
14822 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
14823 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
14824 * keyboard.h (last_event_timestamp): Likewise.
14825 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
14826 * menu.h (xmenu_show): Likewise.
14827 * term.c (term_mouse_position): Likewise.
14828 * termhooks.h (struct input_event.timestamp): Likewise.
14829 (struct terminal.mouse_position_hook): Likewise.
14830 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
14831 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
14832 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
14833 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
14834 what it was before.
14835 * menu.h, termhooks.h: Include "systime.h", for Time.
14837 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
14838 Don't assume that the difference between two unsigned long values
14839 can fit into an integer. At this point, we know button_down_time
14840 <= event->timestamp, so the difference must be nonnegative, so
14841 there's no need to cast the result if double-click-time is
14842 nonnegative, as it should be; check that it's nonnegative, just in
14843 case. This bug is triggered when events are more than 2**31 ms
14844 apart (about 25 days). (Bug#8664)
14846 * xselect.c (last_event_timestamp): Remove duplicate decl.
14847 (x_own_selection): Remove needless cast to unsigned long.
14849 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
14850 that always fit in int. Use a sentinel instead of a counter, to
14851 avoid a temp and to allay GCC's concerns about possible int overflow.
14852 * frame.h (struct frame): Use int for menu_bar_items_used
14853 instead of EMACS_INT, since it always fits in int.
14855 * menu.c (grow_menu_items): Check for int overflow.
14857 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
14859 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
14860 Before, the code was not consistent. These values cannot exceed
14861 2**31 - 1 so there's no need to make them unsigned.
14862 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
14863 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
14864 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
14866 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
14868 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
14869 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
14870 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
14871 presumably because the widths might not match.
14873 * window.c (size_window): Avoid needless test at loop start.
14875 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
14877 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
14879 2011-05-12 Drew Adams <drew.adams@oracle.com>
14881 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
14883 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14885 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
14886 `width' to `bar_area_x' and `bar_area_width', respectively.
14887 (x_scroll_run): Take account of fringe background extension.
14889 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
14890 Rename local vars `left' and `width' to `bar_area_x' and
14891 `bar_area_width', respectively.
14892 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
14893 background extension.
14895 2011-05-10 Jim Meyering <meyering@redhat.com>
14897 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
14899 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
14901 * image.c (Finit_image_library): Return t for built-in image types,
14902 like pbm and xbm. (Bug#8640)
14904 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
14906 * w32menu.c (set_frame_menubar): Fix submenu allocation.
14908 2011-05-07 Eli Zaretskii <eliz@gnu.org>
14910 * w32console.c (Fset_screen_color): Doc fix.
14911 (Fget_screen_color): New function.
14912 (syms_of_ntterm): Defsubr it.
14914 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
14915 unlink the temporary file if Fcall_process didn't create it in the
14917 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
14918 child process will be redirected to a file specified with `:file'.
14919 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
14920 cue to call_process_cleanup not to close that handle.
14922 2011-05-07 Ben Key <bkey76@gmail.com>
14924 * makefile.w32-in: The bootstrap-temacs rule now makes use of
14925 one of two shell specific rules, either bootstrap-temacs-CMD or
14926 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
14927 to the previous implementation of the bootstrap-temacs rule.
14928 The bootstrap-temacs-CMD rule is similar to the previous
14929 implementation of the bootstrap-temacs rule except that it
14930 makes use of the ESC_CFLAGS variable instead of the CFLAGS
14933 These changes, along with some changes to nt/configure.bat,
14934 nt/gmake.defs, and nt/nmake.defs, are required to extend my
14935 earlier fix to add support for --cflags and --ldflags options
14936 that include quotes so that it works whether make uses cmd or
14939 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
14941 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
14942 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
14944 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
14945 a string. Handle both cases.
14946 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
14947 (Fdbus_register_method): Use Qinvalid_function.
14949 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
14951 * makefile.w32-in: Update dependencies.
14952 (LISP_H): Add inttypes.h and stdin.h.
14953 (PROCESS_H): Add unistd.h.
14955 2011-05-06 Eli Zaretskii <eliz@gnu.org>
14957 * lread.c: Include limits.h (fixes the MS-Windows build broken by
14958 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
14960 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
14962 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
14964 * term.c (vfatal): Remove stray call to va_end.
14965 It's not needed and the C Standard doesn't allow it here anyway.
14967 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
14968 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
14970 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
14973 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
14975 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
14977 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
14979 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
14981 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
14983 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
14984 * charset.c (Fdefine_charset_internal): Don't initialize
14985 charset.code_space[15]. The value was garbage, on hosts with
14986 32-bit int (Bug#8600).
14988 * lread.c (read_integer): Be more consistent with string-to-number.
14989 Use string_to_number to do the actual conversion; this avoids
14990 rounding errors and fixes some other screwups. Without this fix,
14991 for example, #x1fffffffffffffff was misread as -2305843009213693952.
14992 (digit_to_number): Move earlier, for benefit of read_integer.
14993 Return -1 if the digit is out of range for the base, -2 if it is
14994 not a digit in any supported base. (Bug#8602)
14996 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
14998 * dispnew.c (scrolling_window): Return 1 if we scrolled,
14999 to match comment at start of function. This also removes a
15000 GCC warning about overflow in a 32+64-bit port.
15002 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
15004 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
15005 Reported by Stefan Monnier in
15006 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
15007 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
15008 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
15010 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
15011 (EMACS_UINTPTR): Likewise, with uintptr_t.
15013 * lisp.h: Prefer 64-bit EMACS_INT if available.
15014 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
15015 on 32-bit hosts that have 64-bit int, so that they can access
15017 However, temporarily disable this change unless the temporary
15018 symbol WIDE_EMACS_INT is defined.
15020 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
15022 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
15023 This removes an assumption that EMACS_INT and long are the same
15024 width as pointers. The assumption is true for Emacs porting targets
15025 now, but we want to make other targets possible.
15026 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
15027 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
15028 In the rest of the code, change types of integers that hold casted
15029 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
15030 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
15031 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
15032 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
15033 No need to cast type when ORing.
15034 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
15035 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
15036 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
15037 assume EMACS_INT is the same width as char *.
15038 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
15039 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
15040 Remove no-longer-needed casts.
15041 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
15042 (xg_tool_bar_help_callback, xg_make_tool_item):
15043 Use EMACS_INTPTR to hold an integer
15044 that will be cast to void *; this can avoid a GCC warning
15045 if EMACS_INT is not the same width as void *.
15046 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
15047 * xdisp.c (display_echo_area_1, resize_mini_window_1):
15048 (current_message_1, set_message_1):
15049 Use a local to convert to proper width without a cast.
15050 * xmenu.c (dialog_selection_callback): Likewise.
15052 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
15053 Also, don't assume VALBITS / RAND_BITS is less than 5,
15054 and don't rely on undefined behavior when shifting a 1 left into
15056 * lisp.h (get_random): Change signature to match.
15058 * lread.c (hash_string): Use size_t, not int, for hash computation.
15059 Normally we prefer signed values; but hashing is special, because
15060 it's better to use unsigned division on hash table sizes so that
15061 the remainder is nonnegative. Also, size_t is the natural width
15062 for hashing into memory. The previous code used 'int', which doesn't
15063 retain enough info to hash well into very large tables.
15064 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
15066 * dbusbind.c: Don't possibly lose pointer info when converting.
15067 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
15068 Use XPNTR rather than XHASH, so that the high-order bits of
15069 the pointer aren't lost when converting through void *.
15071 * eval.c (Fautoload): Don't double-shift a pointer.
15073 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
15075 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
15077 * gnutls.c (DEF_GNUTLS_FN):
15078 * image.c (DEF_IMGLIB_FN): Make function pointers static.
15080 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
15082 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
15085 2011-05-05 Eli Zaretskii <eliz@gnu.org>
15087 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
15088 New version that can reserve upto 2GB of heap space.
15090 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
15092 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
15094 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
15096 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
15097 `gnutls_certificate_set_x509_key_file'.
15099 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
15101 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
15102 Update dependencies.
15104 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
15106 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
15107 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
15108 Remove unused parameter `fildes'.
15109 * process.c (read_process_output, send_process): Don't pass it.
15111 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
15113 Fix previous change: the library cache is defined in w32.c.
15114 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
15115 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
15117 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
15119 Implement dynamic loading of GnuTLS on Windows.
15121 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
15122 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
15123 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
15126 * gnutls.c (Qgnutls_dll): Define.
15127 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
15128 (gnutls_*): Declare function pointers.
15129 (init_gnutls_functions): New function to initialize function pointers.
15130 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
15131 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
15132 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
15133 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
15134 (emacs_gnutls_write, emacs_gnutls_read)
15135 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
15136 (Fgnutls_available_p): New function.
15137 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
15138 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
15139 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
15141 * image.c: Include w32.h.
15142 (Vimage_type_cache): Delete.
15143 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
15144 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
15145 (w32_delayed_load): Move to w32.c.
15147 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
15149 * w32.c (QCloaded_from, Vlibrary_cache): Define.
15150 (w32_delayed_load): Move from image.c. When loading a library, record
15151 its filename in the :loaded-from property of the library id.

15241 produced by %s or %c overflows available buffer space. (Bug#8545)
15243 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
15245 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).

15255 (command_loop_1): Run `delayed-warnings-hook'
15256 if Vdelayed_warnings_list is non-nil.
15257 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
15258 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
15260 2011-04-28 Eli Zaretskii <eliz@gnu.org>
15262 * doprnt.c (doprnt): Don't return value smaller than the buffer
15263 size if the message was truncated. (Bug#8545).

15274 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
15276 * makefile.w32-in: Update dependencies.
15278 2011-04-27 Eli Zaretskii <eliz@gnu.org>
15280 Improve `doprnt' and its usage. (Bug#8545)
15281 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
15282 `format_end'. Remove support for %l as a conversion specifier.
15283 Don't use xrealloc. Improve diagnostics when the %l size modifier
15284 is used. Update the commentary.
15286 * eval.c (verror): Simplify calculation of size_t.
15288 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
15291 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
15293 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
15296 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
15298 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
15299 This makes this file independent of the recent pseudovector change.
15301 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
15303 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
15305 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
15306 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
15307 Remove unused local.
15308 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
15310 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
15311 GCC 4.6.0 optimizes based on type-based alias analysis.
15312 For example, if b is of type struct buffer * and v of type struct
15313 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
15314 != &v->size, and therefore "v->size = 1; b->size = 2; return
15315 v->size;" must therefore return 1. This assumption is incorrect
15316 for Emacs, since it type-puns struct Lisp_Vector * with many other
15317 types. To fix this problem, this patch adds a new type struct
15318 vectorlike_header that documents the constraints on layout of vectors
15319 and pseudovectors, and helps optimizing compilers not get fooled
15320 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
15321 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
15322 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
15324 (XSETPVECTYPE): Rewrite in terms of new macro.
15325 (XSETPVECTYPESIZE): New macro, specifying both type and size.
15326 This is a bit clearer, and further avoids the possibility of
15327 undesirable aliasing.
15328 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
15329 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
15330 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
15331 since Lisp_Subr is a special case (no "next" field).
15332 (ASIZE): Now uses header.size rather than size.
15333 All previous uses of XVECTOR (foo)->size replaced to use this macro,
15334 to avoid the hassle of writing XVECTOR (foo)->header.size.
15335 (struct vectorlike_header): New type.
15336 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
15337 object, to help avoid aliasing.
15338 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
15339 (SUBRP): Likewise, since Lisp_Subr is a special case.
15340 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
15341 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
15342 (struct Lisp_Hash_Table): Combine first two members into a single
15343 struct vectorlike_header member. All uses of "size" and "next" members
15344 changed to be "header.size" and "header.next".
15345 * buffer.h (struct buffer): Likewise.
15346 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
15347 * frame.h (struct frame): Likewise.
15348 * process.h (struct Lisp_Process): Likewise.
15349 * termhooks.h (struct terminal): Likewise.
15350 * window.c (struct save_window_data, struct saved_window): Likewise.
15351 * window.h (struct window): Likewise.
15352 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
15353 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
15354 * buffer.c (init_buffer_once): Likewise.
15355 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
15357 * process.c (Fformat_network_address): Use local var for size,
15360 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
15362 Make the Lisp reader and string-to-float more consistent (Bug#8525)
15363 * data.c (atof): Remove decl; no longer used or needed.
15364 (digit_to_number): Move to lread.c.
15365 (Fstring_to_number): Use new string_to_number function, to be
15366 consistent with how the Lisp reader treats infinities and NaNs.
15367 Do not assume that floating-point numbers represent EMACS_INT
15368 without losing information; this is not true on most 64-bit hosts.
15369 Avoid double-rounding errors, by insisting on integers when
15370 parsing non-base-10 numbers, as the documentation specifies.
15371 * lisp.h (string_to_number): New decl, replacing ...
15372 (isfloat_string): Remove.
15373 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
15374 (read1): Do not accept +. and -. as integers; this
15375 appears to have been a coding error. Similarly, do not accept
15376 strings like +-1e0 as floating point numbers. Do not report
15377 overflow for integer overflows unless the base is not 10 which
15378 means we have no simple and reliable way to continue.
15379 Break out the floating-point parsing into a new
15380 function string_to_number, so that Fstring_to_number parses
15381 floating point numbers consistently with the Lisp reader.
15382 (digit_to_number): Move here from data.c. Make it static inline.
15383 (E_CHAR, EXP_INT): Remove, replacing with ...
15384 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
15385 (string_to_number): New function, replacing isfloat_string.
15386 This function checks for valid syntax and produces the resulting
15387 Lisp float number too. Rework it so that string-to-number
15388 no longer mishandles examples like "1.0e+". Use strtoumax,
15389 so that overflow for non-base-10 numbers is reported only when
15390 there's no portable and simple way to convert to floating point.
15392 * textprop.c (set_text_properties_1): Rewrite for clarity,
15393 and to avoid GCC warning about integer overflow.
15395 * intervals.h (struct interval): Use EMACS_INT for members
15396 where EMACS_UINT might cause problems. See
15397 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
15398 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
15399 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
15401 (offset_intervals): Tell GCC not to worry about length overflow
15402 when negating a negative length.
15404 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
15405 (overrun_check_free): Likewise.
15407 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
15408 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
15411 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
15412 (gnutls_make_error): Rename local to avoid shadowing.
15413 (gnutls_emacs_global_deinit): ifdef out; not used.
15414 (Fgnutls_boot): Use const for pointer to readonly storage.
15415 Comment out unused local. Fix pointer signedness problems.
15417 * lread.c (openp): Don't stuff size_t into an 'int'.
15418 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
15419 about possible signed overflow.
15421 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
15422 (GDK_KEY_g): Don't define if already defined.
15423 (xg_prepare_tooltip): Avoid pointer signedness problem.
15424 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
15426 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
15427 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
15429 * xfns.c (Fx_window_property): Simplify a bit,
15430 to make a bit faster and to avoid GCC 4.6.0 warning.
15431 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
15433 * fns.c (internal_equal): Don't assume size_t fits in int.
15435 * alloc.c (compact_small_strings): Tighten assertion a little.
15437 Replace pEd with more-general pI, and fix some printf arg casts.
15438 * lisp.h (pI): New macro, generalizing old pEd macro to other
15439 conversion specifiers. For example, use "...%"pI"d..." rather
15440 than "...%"pEd"...".
15441 (pEd): Remove. All uses replaced with similar uses of pI.
15442 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
15443 * alloc.c (check_pure_size): Don't overflow by converting size to int.
15444 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
15445 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
15446 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
15447 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
15448 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
15450 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
15451 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
15452 * print.c (safe_debug_print, print_object): Likewise.
15453 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
15455 Use pI instead of if-then-else-abort. Use %p to avoid casts,
15456 avoiding the 0 flag, which is not portable.
15457 * process.c (Fmake_network_process): Use pI to avoid cast.
15458 * region-cache.c (pp_cache): Likewise.
15459 * xdisp.c (decode_mode_spec): Likewise.
15460 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
15461 behavior on 64-bit hosts with printf arg.
15462 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
15463 (x_stop_queuing_selection_requests): Likewise.
15464 (x_get_window_property): Don't truncate byte count to an 'int'
15467 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
15468 here, since it parses constructs like leading '-' and spaces,
15469 which are not wanted; and it overflows with large numbers.
15470 Instead, simply match F[0-9]+, which is what is wanted anyway.
15472 * alloc.c: Remove unportable assumptions about struct layout.
15473 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
15474 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
15475 (allocate_vectorlike, make_pure_vector): Use the new macros,
15476 plus offsetof, to remove unportable assumptions about struct layout.
15477 These assumptions hold on all porting targets that I know of, but
15478 they are not guaranteed, they're easy to remove, and removing them
15479 makes further changes easier.
15481 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
15482 This doesn't fix a bug but makes the code clearer.
15483 (string_overrun_cookie): Now const. Use initializers that
15484 don't formally overflow signed char, to avoid warnings.
15485 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
15486 can cause Emacs to crash when string overrun checking is enabled.
15487 (allocate_buffer): Don't assume sizeof (struct buffer) is a
15488 multiple of sizeof (EMACS_INT); it need not be, if
15489 alignof(EMACS_INT) < sizeof (EMACS_INT).
15490 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
15492 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

15496 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
15498 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
15499 supposed to be handshaking. (Bug#8556)
15500 Reported by Paul Eggert <eggert@cs.ucla.edu>.

15504 * lisp.h (Qdebug): List symbol.
15505 * eval.c (Qdebug): Restore global linkage.
15506 * keyboard.c (debug-on-event): New variable.
15507 (handle_user_signal): Break into debugger when debug-on-event
15508 matches the current signal symbol.
15510 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
15512 * alloc.c (check_sblock, check_string_bytes)
15513 (check_string_free_list): Convert to standard C.
15515 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
15517 * w32.c (emacs_gnutls_push): Fix typo.
15519 2011-04-25 Eli Zaretskii <eliz@gnu.org>
15521 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
15522 "cast to pointer from integer of different size".
15524 Improve doprnt and its use in verror. (Bug#8545)
15525 * doprnt.c (doprnt): Document the set of format control sequences
15526 supported by the function. Use SAFE_ALLOCA instead of always
15529 * eval.c (verror): Don't limit the buffer size at size_max-1, that
15530 is one byte too soon. Don't use xrealloc; instead xfree and
15533 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
15535 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
15538 * gnutls.c: Renamed global_initialized to
15539 gnutls_global_initialized. Added internals for the
15540 :verify-hostname-error, :verify-error, and :verify-flags
15541 parameters of `gnutls-boot' and documented those parameters in the
15542 docstring. Start callback support.
15543 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
15544 unless a fatal error occurred. Call gnutls_alert_send_appropriate
15545 on error. Return error code.
15546 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
15547 (emacs_gnutls_read): Likewise.
15548 (Fgnutls_boot): Return handshake error code.
15549 (emacs_gnutls_handle_error): New function.
15550 (wsaerror_to_errno): Likewise.

15553 (emacs_gnutls_push): Likewise.
15555 * w32.c (emacs_gnutls_pull): New function for GnuTLS on Woe32.
15556 (emacs_gnutls_push): Likewise.
15558 2011-04-24 Claudio Bley <claudio.bley@gmail.com> (tiny change)
15560 * process.c (wait_reading_process_output): Check if GnuTLS
15561 buffered some data internally if no FDs are set for TLS
15564 * makefile.w32-in (OBJ2): Add gnutls.$(O).
15565 (LIBS): Link to USER_LIBS.

15570 * xdisp.c (handle_single_display_spec): Rename the
15571 display_replaced_before_p argument into display_replaced_p, to
15572 make it consistent with the commentary. Fix typos in the
15575 * textprop.c (syms_of_textprop): Remove dead code.
15576 (copy_text_properties): Delete obsolete commentary about an
15577 interface that was deleted long ago. Fix typos in the description

15581 to changes in oldXMenu/XMenu.h from 2011-04-16.
15582 <menu_help_message, prev_menu_help_message>: Constify.

15873 * process.c (send_process): Adjust to the new signatures of
15874 emacs_write and emacs_gnutls_write. Do not attempt to store

16067 * font.c (font_close_object): Now static.
16068 * font.h (font_close_object): Remove.
16069 * fontset.c (FONTSET_OBJLIST): Remove.
16070 (free_realized_fontset) #if-0 the body, which does nothing.
16071 (face_suitable_for_char_p): #if-0, as it's never called.
16072 * fontset.h (face_suitable_for_char_p): Remove decl.
16073 * xfaces.c (face_at_string_position):
16074 Use FACE_SUITABLE_FOR_ASCII_CHAR_P, not FACE_SUITABLE_FOR_CHAR_P,
16075 since 0 is always ASCII.
16077 * fns.c (weak_hash_tables): Now static.
16079 * fileio.c: Make symbols static if they're not exported.
16080 (auto_saving, auto_save_mode_bits, auto_save_error_occurred):

16098 * editfns.c, lisp.h (get_operating_system_release): Remove.
16099 * process.c (init_process) [DARWIN_OS]: Do it inline, as it is not
16100 worth the hassle of breaking this out.
16102 * xterm.c: Make symbols static if they're not exported.
16103 (x_raise_frame, x_lower_frame, x_wm_set_window_state):
16104 (x_wm_set_icon_pixmap, x_initialize, XTread_socket_fake_io_error):

16206 * buffer.c (buffer_count): Remove unused var.

16215 * atimer.h (run_all_atimers): Remove; not exported.
16217 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
16218 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
16219 was inaccessible from Lisp.
16220 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
16221 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
16223 alloc.c: Import and export fewer symbols, and remove unused items.
16224 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
16226 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
16227 it's not optimized away by whole-program optimization.
16228 (message_enable_multibyte, free_misc): Remove.
16229 (catchlist, handlerlist, mark_backtrace):
16230 Declare only if BYTE_MARK_STACK.

16239 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
16240 (mark_backtrace): Define only if BYTE_MARK_STACK.
16241 * xdisp.c (message_enable_multibyte): Now static.
16243 Declare Lisp_Object Q* variables to be 'static' if not exported.
16244 This makes it easier for human readers (and static analyzers)
16245 to see whether these variables are used from other modules.
16246 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
16247 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
16248 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:

16256 Remove decls of unexported vars.
16257 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
16259 * lisp.h (DEFINE_FUNC): Make sname 'static'.
16261 Make Emacs functions such as Fatom 'static' by default.
16262 This makes it easier for human readers (and static analyzers)
16263 to see whether these functions can be called from other modules.
16264 DEFUN now defines a static function. To make the function external
16265 so that it can be used in other C modules, use the new macro DEFUE.
16266 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
16267 (Finit_image_library):
16268 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
16269 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
16270 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
16271 Remove decls, since these functions are now static.
16272 (Funintern, Fget_internal_run_time): New decls, since these functions
16273 were already external.
16275 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
16276 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

16282 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
16283 Mark functions with DEFUE instead of DEFUN,
16284 if they are used in other modules.
16285 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
16286 decls for now-static functions.
16287 * buffer.h (Fdelete_overlay): Remove decl.
16288 * callproc.c (Fgetenv_internal): Mark as internal.
16289 * composite.c (Fremove_list_of_text_properties): Remove decl.

16295 (Funintern): Remove extern decl; now in .h file where it belongs.
16296 * fileio.c (Fmake_symbolic_link): New forward static decl.
16297 * image.c (Finit_image_library): New forward static decl.
16298 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
16299 * intervals.h (Fprevious_property_change):
16300 (Fremove_list_of_text_properties): Remove decls.
16301 * keyboard.c (Fthis_command_keys): Remove decl.
16302 (Fcommand_execute): New forward static decl.
16303 * keymap.c (Flookup_key): New forward static decl.
16304 (Fcopy_keymap): Now static.
16305 * keymap.h (Flookup_key): Remove decl.
16306 * process.c (Fget_process): New forward static decl.
16307 (Fprocess_datagram_address): Mark as internal.

16318 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
16320 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
16323 2011-04-13 Eli Zaretskii <eliz@gnu.org>
16325 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
16326 when at ZV. (Bug#8487)
16328 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
16330 * charset.c (Fclear_charset_maps): Use xfree instead of free.
16332 * keyboard.c (parse_tool_bar_item): Likewise.
16333 * sound.c (sound_cleanup, alsa_close): Likewise.
16334 * termcap.c (tgetent): Likewise.
16335 * xfns.c (x_default_font_parameter): Likewise.
16336 * xsettings.c (read_and_apply_settings): Likewise.
16338 * alloc.c (overrun_check_malloc, overrun_check_realloc)
16339 (overrun_check_free): Protoize.
16341 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
16343 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
16344 since callers should never pass a negative size.
16345 Change the signature to match that of plain 'read' and 'write'; see
16346 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
16347 * lisp.h: Update prototypes of emacs_write and emacs_read.
16349 2011-04-11 Eli Zaretskii <eliz@gnu.org>
16351 * xdisp.c (redisplay_window): Don't try to determine the character
16352 position of the scroll margin if the window start point w->startp
16353 is outside the buffer's accessible region. (Bug#8468)
16355 2011-04-10 Eli Zaretskii <eliz@gnu.org>
16357 Fix write-region and its subroutines for buffers > 2GB.
16358 * fileio.c (a_write, e_write): Modify declaration of arguments and
16359 local variables to support buffers larger than 2GB.
16360 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
16362 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
16363 argument, local variables, and return value.
16365 * lisp.h: Update prototypes of emacs_write and emacs_read.
16367 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
16369 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
16371 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
16373 Fix more problems found by GCC 4.6.0's static checks.
16375 * xdisp.c (vmessage): Use a better test for character truncation.
16377 * charset.c (load_charset_map): <, not <=, for optimization,
16378 and to avoid potential problems with integer overflow.
16379 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
16380 * casetab.c (set_identity, shuffle): Likewise.
16381 * editfns.c (Fformat): Likewise.
16382 * syntax.c (skip_chars): Likewise.
16384 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
16385 This also lets GCC 4.6.0 generate slightly better loop code.
16387 * callint.c (Fcall_interactively): <, not <=, for optimization.
16388 (Fcall_interactively): Count the number of arguments produced,
16389 not the number of arguments given. This is simpler and lets GCC
16390 4.6.0 generate slightly better code.
16392 * ftfont.c: Distingish more carefully between FcChar8 and char.
16393 The previous code passed unsigned char * to a functions like
16394 strlen and xstrcasecmp that expect char *, which does not
16395 conform to the C standard.
16396 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
16397 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
16398 char * when the C standard requires it.
16400 * keyboard.c (read_char): Remove unused var.
16402 * eval.c: Port to Windows vsnprintf (Bug#8435).
16403 Include <limits.h>.
16404 (SIZE_MAX): Define if the headers do not.
16405 (verror): Do not give up if vsnprintf returns a negative count.
16406 Instead, grow the buffer. This ports to Windows vsnprintf, which
16407 does not conform to C99. Problem reported by Eli Zaretskii.
16408 Also, simplify the allocation scheme, by avoiding the need for
16409 calling realloc, and removing the ALLOCATED variable.
16411 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
16413 Remove invocations of doprnt, as Emacs now uses vsnprintf.
16414 But keep the doprint source code for now, as we might revamp it
16415 and use it again (Bug#8435).
16416 * lisp.h (doprnt): Remove.
16417 * Makefile.in (base_obj): Remove doprnt.o.
16418 * deps.mk (doprnt.o): Remove.
16420 error: Print 32- and 64-bit integers portably (Bug#8435).
16421 Without this change, on typical 64-bit hosts error ("...%d...", N)
16422 was used to print both 32- and 64-bit integers N, which relied on
16423 undefined behavior.
16424 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
16425 * lisp.h (error, verror): Mark as printf-like functions.
16426 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
16427 Report overflow in size calculations when allocating printf buffer.
16428 Do not truncate output string at its first null byte.
16429 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
16430 Truncate the output at a character boundary, since vsnprintf does not
16432 * charset.c (check_iso_charset_parameter): Convert internal
16433 character to string before calling 'error', since %c now has the
16435 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
16436 overflow when computing char to be passed to 'error'. Do not
16437 pass Lisp_Object to 'error'; pass the integer instead.
16438 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
16439 formatted with plain %d.
16441 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
16443 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
16445 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
16447 * xterm.c (x_catch_errors): Remove duplicate declaration.
16449 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
16451 * xdisp.c, lisp.h (message_nolog): Remove; unused.
16453 2011-04-10 Jim Meyering <meyering@redhat.com>
16455 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
16456 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
16457 return ssize_t not "int", and use size_t as the buffer length.
16458 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
16459 * gnutls.h: Update declarations.
16460 * process.c (read_process_output): Use ssize_t, to match.
16461 (send_process): Likewise.
16463 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
16465 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.

16477 2011-04-09 Eli Zaretskii <eliz@gnu.org>
16479 Fix some uses of `int' instead of EMACS_INT.
16480 * search.c (string_match_1, fast_string_match)
16481 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
16482 (scan_buffer, find_next_newline_no_quit)
16483 (find_before_next_newline, search_command, Freplace_match)
16484 (Fmatch_data): Make some `int' variables be EMACS_INT.
16486 * xdisp.c (display_count_lines): 3rd argument and return value now
16487 EMACS_INT. All callers changed.
16488 (pint2hrstr): Last argument is now EMACS_INT.

16534 (Qhelp_form_show): New var.
16535 (syms_of_keyboard): Use DEFSYM macro.
16537 * print.c (internal_with_output_to_temp_buffer): Function deleted.

16571 to system-supplied API.
16573 * eval.c (Fsignal): Remove excess argument to 'fatal'.
16575 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
16576 This avoids several warnings with gcc -Wstrict-overflow.
16577 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
16578 directly, rather than having caller test rule sign. This avoids
16579 some unnecessary tests.
16580 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
16581 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
16582 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
16584 * xfont.c (xfont_text_extents): Remove var that was set but not used.
16585 (xfont_open): Avoid unnecessary tests.
16587 * composite.c (composition_gstring_put_cache): Use unsigned integer.
16589 * composite.h, composite.c (composition_gstring_put_cache):
16590 Use EMACS_INT, not int, for length.
16592 * composite.h (COMPOSITION_DECODE_REFS): New macro,
16593 breaking out part of COMPOSITION_DECODE_RULE.
16594 (COMPOSITION_DECODE_RULE): Use it.
16595 * composite.c (get_composition_id): Remove unused local vars,
16596 by using the new macro.
16598 * textprop.c (set_text_properties_1): Change while to do-while,
16599 since the condition is always true at first.
16601 * intervals.c (graft_intervals_into_buffer): Mark var as used.
16602 (interval_deletion_adjustment): Return unsigned value.
16605 * process.c (list_processes_1, create_pty, read_process_output):
16606 (exec_sentinel): Remove vars that were set but not used.
16607 (create_pty): Remove unnecessary "volatile"s.
16608 (Fnetwork_interface_info): Avoid possibility of int overflow.

16621 * print.c (print_error_message): Avoid int overflow.
16623 * font.c (font_list_entities): Redo for clarity,
16624 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
16626 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
16627 (font_score): Avoid potential overflow in diff calculation.
16629 * fns.c (substring_both): Remove var that is set but not used.
16630 (sxhash): Redo loop for clarity and to avoid wraparound warning.
16632 * eval.c (funcall_lambda): Rename local to avoid shadowing.
16634 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
16635 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
16636 can always succeed if overflow has undefined behavior.
16638 * search.c (boyer_moore, wordify): Remove vars set but not used.
16639 (wordify): Omit three unnecessary tests.
16641 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.

16650 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
16651 (Finsert_file_contents): Remove unnecessary code checking fd.
16653 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
16654 Check for integer overflow on size calculations.
16656 * buffer.c (Fprevious_overlay_change): Remove var that is set
16659 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
16660 Remove vars that are set but not used.
16661 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
16662 (timer_check_2): Mark vars as initialized.
16664 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
16666 * image.c (lookup_image): Remove var that is set but not used.
16667 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
16669 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
16670 that are set but not used.
16672 * xfns.c (make_invisible_cursor): Don't return garbage
16673 if XCreateBitmapFromData fails (Bug#8410).
16675 * xselect.c (x_get_local_selection, x_handle_property_notify):
16676 Remove vars that are set but not used.
16678 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
16679 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
16681 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
16682 Remove var that is set but not used.
16683 (scroll_bar_windows_size): Now size_t, not int.
16684 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
16685 Check for overflow.
16687 * xfaces.c (realize_named_face): Remove vars that are set but not used.
16688 (map_tty_color) [!defined MSDOS]: Likewise.
16690 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
16692 * coding.c: Remove vars that are set but not used.
16693 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
16694 All callers changed.
16695 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
16696 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
16697 (decode_coding_charset): Remove vars that are set but not used.
16699 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
16700 that is set but not used.
16702 * print.c (print_object): Remove var that is set but not used.
16704 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
16705 The gnulib version avoids calling malloc in the usual case,
16706 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
16707 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
16708 * filelock.c (current_lock_owner): Likewise.
16709 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
16710 * sysdep.c: Include allocator.h, careadlinkat.h.
16711 (emacs_no_realloc_allocator): New static constant.
16712 (emacs_readlink): New function.
16713 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
16714 ../lib/careadlinkat.h.
16716 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
16718 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
16719 first non-nil return value).
16721 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
16723 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
16724 if not defined (Bug#8403).
16726 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
16728 * xdisp.c (display_count_lines): Remove parameter `start',
16729 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
16730 (get_char_face_and_encoding): Remove parameter `multibyte_p',
16731 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

16733 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
16734 and thereabouts. All callers changed.
16735 (get_per_char_metric): Remove parameter `f', unused since
16736 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
16738 2011-04-02 Jim Meyering <meyering@redhat.com>
16740 do not dereference NULL upon failed strdup
16741 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
16742 (ns_get_family): Likewise.
16744 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
16746 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
16748 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
16750 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
16753 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
16755 Add lexical binding.
16757 * window.c (Ftemp_output_buffer_show): New fun.
16758 (Fsave_window_excursion):
16759 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
16761 * lread.c (lisp_file_lexically_bound_p): New function.
16762 (Fload): Bind Qlexical_binding.
16763 (readevalloop): Remove `evalfun' arg.
16764 Bind Qinternal_interpreter_environment.
16765 (Feval_buffer): Bind Qlexical_binding.
16766 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
16768 (syms_of_lread): Declare `lexical-binding'.
16770 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
16772 * keyboard.c (eval_dyn): New fun.
16773 (menu_item_eval_property): Use it.
16775 * image.c (parse_image_spec): Use Ffunctionp.
16777 * fns.c (concat, mapcar1): Accept byte-code-functions.
16779 * eval.c (Fsetq): Handle lexical vars.
16780 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
16781 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
16782 (FletX, Flet): Obey lexical binding.
16783 (Fcommandp): Handle closures.
16784 (Feval): New `lexical' arg.
16785 (eval_sub): New function extracted from Feval. Use it almost
16786 everywhere where Feval was used. Look up vars in lexical env.
16788 (Ffunctionp): Move from subr.el.
16789 (Ffuncall): Handle closures.
16790 (apply_lambda): Remove `eval_flags'.
16791 (funcall_lambda): Handle closures and new byte-code-functions.
16792 (Fspecial_variable_p): New function.
16793 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
16794 but without exporting it to Lisp.
16796 * doc.c (Fdocumentation, store_function_docstring):
16797 * data.c (Finteractive_form): Handle closures.
16799 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
16802 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
16804 (exec_byte_code): New function extracted from Fbyte_code to handle new
16805 calling convention for byte-code-functions. Add new byte-codes.
16807 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
16809 * alloc.c (Fmake_symbol): Init new `declared_special' field.
16811 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
16813 * xdisp.c (redisplay_internal): Fix prototype.
16815 2011-03-31 Eli Zaretskii <eliz@gnu.org>
16817 * xdisp.c (SCROLL_LIMIT): New macro.
16818 (try_scrolling): Use it when setting scroll_limit.
16819 Limit scrolling to 100 screen lines.
16820 (redisplay_window): Even when falling back on "recentering",
16821 position point in the window according to scroll-conservatively,
16822 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
16824 (try_scrolling): When point is above the window, allow searching
16825 as far as scroll_max, or one screenful, to compute vertical
16826 distance from PT to the scroll margin position. This prevents
16827 try_scrolling from unnecessarily failing when
16828 scroll-conservatively is set to a value slightly larger than the
16829 window height. Clean up the case of PT below the margin at bottom
16830 of window: scroll_max can no longer be INT_MAX. When aggressive
16831 scrolling is in use, don't let point enter the opposite scroll
16832 margin as result of the scroll.
16833 (syms_of_xdisp) <scroll-conservatively>: Document the
16834 threshold of 100 lines for never-recentering scrolling.
16836 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
16838 * dispextern.h (move_it_by_lines):
16839 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
16840 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
16841 (message_log_check_duplicate): Remove parameters `prev_bol' and
16842 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
16843 (redisplay_internal): Remove parameter `preserve_echo_area',
16844 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
16846 * indent.c (Fvertical_motion):
16847 * window.c (window_scroll_pixel_based, Frecenter):
16848 Don't pass `need_y_p' to `move_it_by_lines'.
16850 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
16852 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
16853 steal a few bits to be more compact.
16854 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
16855 Remove unneeded casts.
16857 * bytecode.c (Fbyte_code): CAR and CDR can GC.
16859 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
16861 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
16862 binding" message (bug#7967).
16864 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
16866 Fix more problems found by GCC 4.6.0's static checks.
16868 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
16869 Remove unused local var.
16871 * editfns.c (Fmessage_box): Remove unused local var.
16873 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
16874 (note_mode_line_or_margin_highlight, note_mouse_highlight):
16875 Omit unused local vars.
16876 * window.c (shrink_windows): Omit unused local var.
16877 * menu.c (digest_single_submenu): Omit unused local var.
16878 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
16879 Omit unused local var.
16881 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
16882 Don't assume string length fits in int.
16883 (keyremap_step, read_key_sequence): Use size_t for sizes.
16884 (read_key_sequence): Don't check last_real_key_start redundantly.
16886 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
16887 instead of alloca (Bug#8344).
16889 * eval.c (Fbacktrace): Don't assume nargs fits in int.
16890 (Fbacktrace_frame): Don't assume nframes fits in int.
16892 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
16894 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
16897 * term.c (produce_glyphless_glyph): Remove unnecessary test.
16899 * cm.c (calccost): Turn while-do into do-while, for clarity.
16901 * keyboard.c (syms_of_keyboard): Use the same style as later
16902 in this function when indexing through an array. This also
16903 works around GCC bug 48267.
16905 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
16907 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
16909 * chartab.c (sub_char_table_ref_and_range): Redo for slight
16910 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
16912 * keyboard.c, keyboard.h (num_input_events): Now size_t.
16913 This avoids undefined behavior on integer overflow, and is a bit
16914 more convenient anyway since it is compared to a size_t variable.
16916 Variadic C functions now count arguments with size_t, not int.
16917 This avoids an unnecessary limitation on 64-bit machines, which
16918 caused (substring ...) to crash on large vectors (Bug#8344).
16919 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
16920 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
16921 All variadic functions and their callers changed accordingly.
16922 (struct gcpro.nvars): Now size_t, not int. All uses changed.
16923 * data.c (arith_driver, float_arith_driver): Likewise.
16924 * editfns.c (general_insert_function): Likewise.
16925 * eval.c (struct backtrace.nargs, interactive_p)

17141 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
17143 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
17144 unconditionally since it does the check itself.
17146 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
17148 Fix more problems found by GCC 4.5.2's static checks.
17150 * coding.c (encode_coding_raw_text): Avoid unnecessary test
17151 the first time through the loop, since we know p0 < p1 then.
17152 This also avoids a gcc -Wstrict-overflow warning.
17154 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
17155 leading to a memory leak, possible in functions like
17156 load_charset_map_from_file that can allocate an unbounded number
17157 of objects (Bug#8318).
17159 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
17160 that could (at least in theory) be that large.
17162 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
17163 This is less likely to overflow, and avoids undefined behavior if
17164 overflow does occur. All callers changed. Use strtoul to scan
17165 for the unsigned long integer.

17182 * process.c (Fmake_network_process): Use socklen_t, not int,
17183 where POSIX says socklen_t is required in portable programs.
17184 This fixes a porting bug on hosts like 64-bit HP-UX, where
17185 socklen_t is wider than int (Bug#8277).
17186 (Fmake_network_process, server_accept_connection):
17187 (wait_reading_process_output, read_process_output):
17190 * process.c: Rename or move locals to avoid shadowing.

17202 Include tparam.h instead, since it declares them.
17203 * cm.h (PC): Remove extern decl; tparam.h now does this.
17204 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
17205 * terminfo.c: Include tparam.h, to check interfaces.
17206 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
17207 (tparam): Adjust signature to match interface in tparam.h;
17208 this removes some undefined behavior. Check that outstring and len
17209 are zero, which they always are with Emacs.
17210 * tparam.h (PC, BC, UP): New extern decls.
17212 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
17213 (xftfont_open): Rename locals to avoid shadowing.

17231 (composition_update_it): Mark var as initialized.
17232 (find_automatic_composition): Mark vars as initialized,
17233 with a FIXME (Bug#8290).

17239 (BUF_DEC_POS): Be more systematic about renaming local temporaries
17240 to avoid shadowing.

17252 Fix pointer signedness.
17253 (alsa_choose_format): Remove unused local var.
17254 (wav_play): Initialize a variable to 0, to prevent undefined
17255 behavior (Bug#8278).
17257 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
17259 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
17261 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
17262 clobbering (Bug#8298).
17263 * sysdep.c (sys_subshell): Likewise.
17264 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
17266 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
17267 This should get cleaned up, so that child_setup has the
17268 same signature on all platforms.
17270 * callproc.c (call_process_cleanup): Now static.
17271 (relocate_fd): Rename locals to avoid shadowing.
17273 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
17275 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
17276 not to be necessary, and produces flickering.
17278 2011-03-20 Glenn Morris <rgm@gnu.org>
17280 * config.in: Remove file.
17282 2011-03-20 Juanma Barranquero <lekktu@gmail.com>

17327 Define only if needed.
17329 * unexelf.c (unexec): Name an expression,
17330 to avoid gcc -Wbad-function-cast warning.
17331 Use a different way to cause a compilation error if anyone uses
17332 n rather than nn, a way that does not involve shadowing.
17333 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
17335 * deps.mk (unexalpha.o): Remove; unused.

17401 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
17402 some of which prompt warnings from gcc -Wbad-function-cast.
17403 (Fformat_time_string, Fencode_time, Finsert_char):

17432 (Fmemory_limit): Cast sbrk's returned value to char *.
17434 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this

17440 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
17441 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
17442 to use the following functions instead of these macros.
17443 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
17444 EMACS_INT, since callers assume the returned value fits in int.
17445 (upcase1): Likewise, for UPCASE_TABLE.
17446 (uppercasep, lowercasep, upcase): New static inline functions.
17447 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

17457 (regex_compile, re_match_2_internal): Mark locals as initialized.
17458 (RETALLOC_IF): Define only if needed.
17459 (WORDCHAR_P): Likewise. This one is never needed, but is used
17460 only in a comment talking about a compiler bug, so put inside
17461 the #if 0 of that comment.
17462 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
17463 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

17490 New macros, so that the caller can use some names other than
17491 gcpro1, gcpro2, etc.
17492 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
17494 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
17495 argument, for consistency with GCPRO2_VAR, etc: it is now the
17496 prefix of the variable, not the variable itself. All uses
17498 * dired.c (directory_files_internal, file_name_completion):
17499 Rename locals to avoid shadowing.
17501 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
17502 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
17503 dired.c's scmp function, had undefined behavior.
17504 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
17505 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
17506 * buffer.h: ... to here, because these macros use current_buffer,
17507 and the new implementation with inline functions needs to have
17508 current_buffer in scope now, rather than later when the macros
17510 (downcase, upcase1): New static inline functions.
17511 (DOWNCASE, UPCASE1): Reimplement using these functions.
17512 This avoids undefined behavior in expressions like
17513 DOWNCASE (x) == DOWNCASE (y), which previously suffered
17514 from race conditions in accessing the global variables
17515 case_temp1 and case_temp2.
17516 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
17517 * lisp.h (case_temp1, case_temp2): Remove their decls.
17518 * character.h (ASCII_CHAR_P): Move from here ...
17519 * lisp.h: ... to here, so that the inline functions mentioned
17520 above can use them.

17524 * fileio.c (file_name_as_directory, directory_file_name):

17527 (file_name_as_directory): Use const pointers when appropriate.
17528 (Fexpand_file_name): Likewise. In particular, newdir might
17529 point at constant storage, so make it a const pointer.

17538 to avoid shadowing.
17540 * marker.c (bytepos_to_charpos): Remove; unused.
17542 * lisp.h (verify_bytepos, count_markers): New decls,
17543 so that gcc does not warn that these functions aren't declared.
17545 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
17546 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.

17553 * buffer.c (fix_overlays_before): Mark locals as initialized.
17554 (fix_start_end_in_overlays): Likewise. This function should be
17555 simplified by using pointers-to-pointers, but that's a different

17558 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
17559 (report_overlay_modification): Rename locals to avoid shadowing.

17564 to suppress a gcc -Wclobbered warning that does not seem to be right.
17565 (MAXPATHLEN): Define only if needed.
17567 * process.c (serial_open, serial_configure): Move decls from here ...
17568 * systty.h: ... to here, so that they can be checked.
17570 * fns.c (get_random, seed_random): Move extern decls from here ...
17571 * lisp.h: ... to here, so that they can be checked.

17732 For example, without this patch (encode-time 0 0 0 1 1
17733 1152921504606846976) returns the obviously-bogus value (-948597
17734 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
17735 reports time overflow. See
