59 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
60 Since this stuff is now private to charset.c, there's no need for
61 a public macro and no need to inline by hand.

96 They avoid a race if the timer is too close to the current time.
97 * atimer.c (alarm_timer, alarm_timer_ok) [SIGEV_SIGNAL]: New static vars.
98 (set_alarm) [SIGEV_SIGNAL]: Use POSIX timers if available.

124 * w32.h (Vlibrary_cache): Do not declare.
126 2012-09-25 Eli Zaretskii <eliz@gnu.org>
128 * w32proc.c (sys_signal): Handle all signals defined by the
129 MS-Windows runtime, not just SIGCHLD. Actually install the signal
130 handlers for signals supported by Windows. Don't override
131 term_ntproc as the handler for SIGABRT.
132 (sigaction): Rewrite to call sys_signal instead of duplicating its
134 (sys_kill): Improve commentary.
136 * w32.c (term_ntproc): Accept (and ignore) one argument, for
137 consistency with a signature of a signal handler. All callers
139 (init_ntproc): Accept an argument DUMPING. If dumping, don't
140 install term_ntproc as a signal handler for SIGABRT, as that
141 should be done by the dumped Emacs.
143 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
145 * w32select.c (term_w32select): Protect against repeated
146 invocation by setting clipboard_owner to NULL after calling
149 * emacs.c (shut_down_emacs, main): Adapt the calls to init_ntproc
150 and term_ntproc to their modified signatures.
152 * character.c (char_string, string_char): Remove calls to
153 MAYBE_UNIFY_CHAR. See the discussion starting at

164 when encountering an unknown bytecode.
166 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
168 image.c, indent.c: Use bool for booleans.
169 * dispextern.h (struct image_type): Members valid_p, load, init
170 now return bool, not int. All uses changed.
171 * image.c: Omit unnecessary static decls.
172 (x_create_bitmap_mask, x_build_heuristic_mask):
173 Return void, not int, since callers don't care about the return value.

208 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
210 Move pid_t related decls out of lisp.h.
211 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
212 (interruptible_wait_for_termination):
213 Move these decls from lisp.h to syswait.h, since they use pid_t.
214 Needed on FreeBSD; see Herbert J. Skuhra in
215 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
216 * callproc.c: Include syswait.h.

236 Use bool for boolean.
237 * gtkutil.c (xg_update_frame_menubar):
238 * xmenu.c (update_frame_menubar):
239 Return void, not int, since caller ignores return value.

262 2012-09-23 Eli Zaretskii <eliz@gnu.org>
264 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
265 fatal_error_backtrace.
267 * w32proc.c (sys_kill): Undo last change: don't do anything when
268 invoked to deliver SIGABRT to our own process. This is now
269 handled by emacs_raise.
271 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
273 * w32term.c (w32_read_socket): Remove leftover reference to
274 interrupt_input_pending.
276 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
278 Do not use SA_NODEFER.
279 Problem reported by Dani Moncayo in
280 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
282 * sysdep.c (emacs_abort): Do not reset signal handler.
283 * emacs.c (terminate_due_to_signal): Reset signal handler here.
284 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
285 wanted even on POSIXish hosts, and it doesn't work on Windows.
287 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
289 * xterm.c (x_term_init): Call fixup_locale before and after calling
290 gtk_init (Bug#12392).
292 2012-09-23 Chong Yidong <cyd@gnu.org>
294 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
295 Vdynamic_library_alist.
297 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
298 (Fgnutls_available_p): Caller changed.
300 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
301 (Flibxml_parse_xml_region): Likewise.
303 * dispextern.h (struct image_type): Remove arg from init function.
305 * image.c (Finit_image_library, lookup_image_type)
306 (define_image_type): Remove now-unneeded second arg.
307 (init_xpm_functions, init_png_functions, init_jpeg_functions)
308 (init_tiff_functions, init_gif_functions, init_svg_functions):
309 Arglist and w32_delayed_load calling convention changed.
310 (gs_type): Remove init_gs_functions; there is no such function.
311 (valid_image_p, make_image): Fix caller to lookup_image_type.
313 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
315 Simplify and avoid signal-handling races (Bug#12471).
317 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
318 Avoid recursive loop if there's a fatal error in the function itself.
319 * atimer.c (pending_atimers):
320 * blockinput.h: Don't include "atimer.h"; no longer needed.
321 (interrupt_input_pending): Remove. All uses removed.
322 pending_signals now counts both atimers and ordinary interrupts.
323 This is less racy than having three separate pending-signal flags.
324 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
326 Rename from their upper-case counterparts BLOCK_INPUT,
327 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
328 INPUT_BLOCKED_P, and turn into functions. All uses changed.
329 This makes it easier to access volatile variables more accurately.
330 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
331 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
332 that's more reliable if the code is buggy and sets
333 interrupt_input_blocked to a negative value. All uses changed.
334 * atimer.c (deliver_alarm_signal):
335 Remove. No need to deliver this to the parent; any thread can
336 handle this signal now. All uses replaced by underlying handler.
337 * atimer.c (turn_on_atimers):
338 * dispnew.c (handle_window_change_signal):
339 * emacs.c (handle_danger_signal):
340 * keyboard.c (kbd_buffer_get_event):
341 Don't reestablish signal handler; not needed with sigaction.
342 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
344 Rework to avoid unnecessary accesses to volatile variables.
345 (UNBLOCK_INPUT_TO): Now a function.
346 (totally_unblock_input, unblock_input): New decls.
347 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
348 (init_data): Remove. Necessary stuff now done in init_signal.
349 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
350 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
351 (fatal_error_code): Remove; no longer needed.
352 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
353 it doesn't always backtrace. All uses changed. No need to reset
354 signal to default, since sigaction and/or die does that for us now.
355 Use emacs_raise (FOO), not kill (getpid (), FOO).
356 (main): Check more-accurately whether we're dumping.
357 Move fatal-error setup to sysdep.c
358 * floatfns.c: Do not include "syssignal.h"; no longer needed.
359 * gtkutil.c (xg_get_file_name, xg_get_font):
360 Remove no-longer-needed signal-mask manipulation.
361 * keyboard.c, process.c (POLL_FOR_INPUT):
362 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
363 * keyboard.c (read_avail_input): Remove.
364 All uses replaced by gobble_input.
365 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
366 (kbd_buffer_store_event_hold, gobble_input):
367 (record_asynch_buffer_change) [USABLE_SIGIO]:
368 (store_user_signal_events):
369 No need to mess with signal mask.
370 (gobble_input): If blocking input and there are terminals, simply
371 set pending_signals to 1 and return. All hooks changed to not
372 worry about whether input is blocked.
373 (process_pending_signals): Clear pending_signals before processing
374 them, in case a signal comes in while we're processing.
375 By convention callers now test pending_signals before calling us.
376 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
377 New functions, to support changes to blockinput.h.
378 (handle_input_available_signal): Now extern.
379 (reinvoke_input_signal): Remove. All uses replaced by
381 (quit_count): Now volatile, since a signal handler uses it.
382 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
383 All callers changed. Block SIGINT only if not already blocked.
384 Clear sigmask reliably, even if Fsignal returns, which it can.
385 Omit unnecessary accesses to volatile var.
386 (quit_throw_to_read_char): No need to restore sigmask.
387 * keyboard.c (gobble_input, handle_user_signal):
388 * process.c (wait_reading_process_output):
389 Call signal-handling code rather than killing ourselves.
390 * lisp.h: Include <float.h>, for...
391 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
392 (pending_signals): Now volatile.
393 (syms_of_data): Now const if IEEE floating point.
394 (handle_input_available_signal) [USABLE_SIGIO]:
395 (terminate_due_to_signal, record_child_status_change): New decls.
396 * process.c (create_process): Avoid disaster if memory is exhausted
397 while we're processing a vfork, by tightening the critical section
399 (send_process_frame, process_sent_to, handle_pipe_signal)
400 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
402 (send_process): No need for setjmp/longjmp any more, since the
403 SIGPIPE stuff is now gone. Instead, report an error if errno
405 (record_child_status_change): Now extern. PID and W are now args.
406 Return void, not bool. All callers changed.
407 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
408 Remove. All uses removed. This bug should be fixed now in a
410 (wait_for_termination_1): Use waitpid rather than sigsuspend,
411 and record the child status change directly. This avoids the
412 need to futz with the signal mask.
413 (process_fatal_action): Move here from emacs.c.
414 (emacs_sigaction_flags): New function, containing
415 much of what used to be in emacs_sigaction_init.
416 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
417 caught by emacs, to make races less likely.
418 (deliver_process_signal): Rename from handle_on_main_thread.
420 (BACKTRACE_LIMIT_MAX): Now at top level.
421 (thread_backtrace_buffer, threadback_backtrace_pointers):
423 (deliver_thread_signal, deliver_fatal_thread_signal):
424 New functions, for more-accurate delivery of thread-specific signals.
425 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
426 (deliver_arith_signal): Handle in this thread, not
427 in the main thread, since it's triggered by this thread.
428 (maybe_fatal_sig): New function.
429 (init_signals): New arg DUMPING so that we can be more accurate
430 about whether we're dumping. Caller changed.
431 Treat thread-specific signals differently from process-general signals.
432 Block all signals while handling fatal error; that's safer.
433 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
435 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
436 Ignore SIGPIPE unless batch.
437 (emacs_backtrace): Output backtrace for the appropriate thread,
438 which is not necessarily the main thread.
439 * syssignal.h: Include <stdbool.h>.
440 (emacs_raise): New macro.
441 * xterm.c (x_connection_signal): Remove; no longer needed
442 now that we use sigaction.
443 (x_connection_closed): No need to mess with sigmask now.
444 (x_initialize): No need to reset SIGPIPE handler here, since
445 init_signals does this for us now.
447 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
449 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
450 background rect may be larger (Bug#12245).
452 2012-09-23 Chong Yidong <cyd@gnu.org>
454 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
456 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
458 * .gdbinit: Just stop at fatal_error_backtrace.
459 See Stefan Monnier's request in
460 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
461 Remove no-longer-used query of system type.
463 2012-09-22 Chong Yidong <cyd@gnu.org>
465 * search.c (Freplace_match): Doc fix (Bug#12325).
467 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
469 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
470 (Fline_end_position): Doc fix.
472 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
474 2012-09-22 Chong Yidong <cyd@gnu.org>
476 * dispextern.h (struct image_type): Add new slot, storing a type
477 initialization function.
479 * image.c (define_image_type): Call the image initializer function
480 if it is defined. Arguments and return value changed.
481 (valid_image_p, make_image): Callers changed.
482 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
483 (gif_type, imagemagick_type, svg_type, gs_type):
484 Add initialization functions.
485 (Finit_image_library): Call lookup_image_type.
486 (CHECK_LIB_AVAILABLE): Macro deleted.
487 (lookup_image_type): Call define_image_type here, rather than via
488 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
489 (syms_of_image): Move define_image_type calls for xbm_type and
490 pbm_type to lookup_image_type.
492 2012-09-22 Eli Zaretskii <eliz@gnu.org>
494 * keyboard.c (timer_check_2): Move calculation of 'timers' and
495 'idle_timers' from here ...
496 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
497 lists, to avoid infloops when the timer does something stupid,
498 like reinvoke itself with the same or smaller time-out.
501 2012-09-22 Martin Rudalics <rudalics@gmx.at>
503 * window.c (Fsplit_window_internal): Handle only Qt value of
504 Vwindow_combination_limit separately.
505 (Qtemp_buffer_resize): New symbol.
506 (Vwindow_combination_limit): New default value.
509 2012-09-22 Eli Zaretskii <eliz@gnu.org>
511 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
512 the new overlay string. (Bug#10159)
514 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
516 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
517 or that fprintf is async-signal-safe. POSIX doesn't require
520 2012-09-22 Chong Yidong <cyd@gnu.org>
522 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
525 2012-09-22 Kenichi Handa <handa@gnu.org>
527 * composite.c (composition_reseat_it): Handle the case that a
528 grapheme cluster is not covered by a single font (Bug#12352).
530 2012-09-21 Chong Yidong <cyd@gnu.org>
532 * image.c (define_image_type): Avoid adding duplicate types to
533 image_types (Bug#12463). Suggested by Jörg Walter.
535 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
537 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
538 (print_load_command_name): Add case LC_DATA_IN_CODE.
539 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
541 2012-09-21 Glenn Morris <rgm@gnu.org>
543 * eval.c (Frun_hook_with_args_until_success)
544 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
546 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
548 * fileio.c (Ffile_selinux_context): Only call freecon when
549 lgetfilecon succeeded.
550 (Fset_file_selinux_context): Likewise. (Bug#12444)
552 2012-09-21 Eli Zaretskii <eliz@gnu.org>
554 * xdisp.c (try_window_reusing_current_matrix): Under bidi
555 reordering, locate the cursor by calling set_cursor_from_row; if
556 that fails, clear the desired glyph matrix before returning a
557 failure indication to the caller. Fixes leaving garbled display
558 when fast scrolling with a down-key. (Bug#12403)
559 (compute_stop_pos_backwards): Fix a typo that caused crashes while
560 scrolling through multibyte text.
562 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
564 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
565 calling mark_vectorlike since that's the one that marks the window.
566 (mark_discard_killed_buffers): Mark the final cdr.
567 * window.h (struct window): Move prev/next_buffers to the
569 * window.c (make_window): Initialize prev/next_buffers manually.
571 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
573 Omit unused arg EXPECTED from socket hooks.
574 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
575 * nsterm.m (ns_term_init):
576 * termhooks.h (struct terminal.read_socket_hook):
577 * w32inevt.c (w32_console_read_socket):
578 * w32term.c (w32_read_socket):
579 * xterm.c (XTread_socket):
580 Omit unused arg EXPECTED. All callers changed.
581 (store_user_signal_events): Return void, not int, since callers no
582 longer care about the return value. All uses changed.
584 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
586 * w32gui.h (XParseGeometry): Do not declare.
588 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
590 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
591 Ignore 'expected'. See Eli Zaretskii in
592 <http://bugs.gnu.org/12471#8> (last line).
594 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
595 (XParseGeometry): Now static. Substitute extremal values for
596 values that are out of range.
598 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
600 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
602 * nsfns.m (XParseGeometry): Remove.
603 (Fx_create_frame): Call x_set_offset to correctly interpret
606 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
607 (Fx_parse_geometry): If there is a space in string, call
608 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
610 2012-09-17 Eli Zaretskii <eliz@gnu.org>
612 * search.c (scan_buffer): Use character positions in calls to
613 region_cache_forward and region_cache_backward, not byte
614 positions. (Bug#12196)
616 * w32term.c (w32_read_socket): Set pending_signals to 1, like
617 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
619 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
620 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
621 emacs_blocked_malloc, now deleted.
623 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
625 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
626 The workaround was for improving performance on Solaris 2.4, but
627 is getting in the way now. Emacs will still work if someone is
628 still running Solaris 2.4 in a museum somewhere; Sun dropped
629 support for Solaris 2.4 in 2003.
630 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
631 * process.c (create_process) [HAVE_WORKING_VFORK]:
632 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
633 since Emacs no longer uses vfork on that platform.
635 2012-09-17 Glenn Morris <rgm@gnu.org>
637 * emacs.c: Use COPYRIGHT.
639 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
641 Remove configure's --without-sync-input option (Bug#12450).
642 When auditing signal-handling in preparation for cleaning it up,
643 I found that SYNC_INPUT has race conditions and would be a real
644 pain to fix. Since it's an undocumented and deprecated
645 configure-time option, now seems like a good time to remove it.
646 Also see <http://bugs.gnu.org/11080#16>.
647 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
648 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
649 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
651 (check_depth) [XMALLOC_OVERRUN_CHECK]:
652 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
653 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
654 (dont_register_blocks, bytes_used_when_reconsidered)
655 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
656 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
657 [!SYSTEM_MALLOC && !SYNC_INPUT]:
658 Remove. All uses removed.
659 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
660 implementation, one that depends on whether the new macro
661 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
663 * atimer.c (run_timers, handle_alarm_signal):
664 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
665 (handle_async_input, process_pending_signals)
666 (handle_input_available_signal, init_keyboard):
667 * nsterm.m (ns_read_socket):
668 * process.c (wait_reading_process_output):
669 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
670 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
672 * xterm.c (XTread_socket):
674 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
675 * eval.c (handling_signal): Remove. All uses removed.
676 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
677 All uses replaced with the SYNC_INPUT version.
678 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
680 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
683 * font.c (Ffont_shape_gstring): Remove unused local.
685 2012-09-16 Glenn Morris <rgm@gnu.org>
687 * Makefile.in (clean): No longer run nextstep's clean.
689 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
691 (ns-app): Move here from ns.mk, and simplify.
692 (clean): Simplify nextstep entry.
693 * ns.mk: Remove file.
695 2012-09-17 Kenichi Handa <handa@gnu.org>
697 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
698 not covert the last few charactes.
700 2012-09-16 Kenichi Handa <handa@gnu.org>
702 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
703 here, but just check the validity of glyphs in the glyph-string.
705 2012-09-16 Martin Rudalics <rudalics@gmx.at>
707 * window.c (Fwindow_parameter, Fset_window_parameter):
708 Accept any window as argument (Bug#12452).
710 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
712 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
713 to ns_term_init to avoid memory leak.
715 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
716 explicit retain/release.
717 (ns_term_init): Only allow one display. Initialize outerpool and
720 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
722 Port _setjmp fix to POSIXish hosts as well as Microsoft.
723 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
724 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
725 the Microsoft problem in a different way, by altering ../nt/config.nt.
727 2012-09-15 Eli Zaretskii <eliz@gnu.org>
742 * w16select.c: Remove inclusion of setjmp.h, as it is now included
743 by lisp.h. This completes removal of setjmp.h inclusion
744 erroneously announced in the previous commit. (Bug#12446)
746 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
749 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
750 not defined as a macro. The latter happens on MS-Windows.
753 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
755 Port better to POSIX hosts lacking _setjmp (Bug#12446).
756 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
757 Some instances of '#include <setjmp.h>' removed, if the
758 only reason for the instance was because "lisp.h" was included.
759 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
760 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
761 and _longjmp with the new symbols. Emacs already uses _setjmp if
762 available, so this change affects only POSIXish hosts that have
763 sigsetjmp but not _setjmp, such as some versions of Solaris and
764 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
765 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
766 (png_load_body) [HAVE_PNG]:
767 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
768 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
769 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
770 since PNG requires jmp_buf. This is the only exception to the
771 general rule that we now use sys_setjmp and sys_longjmp.
772 This exception is OK since this code does not change the signal
773 mask or longjmp out of a signal handler.
775 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
777 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
778 Include "syssignal.h", for 'main_thread'.
780 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
782 Avoid out-of-range marker position (Bug#12426).
783 * insdel.c (replace_range, replace_range_2):
784 Adjust markers before overlays, as suggested by comments.
785 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
786 Remove redundant check before calling offset_intervals.
788 2012-09-14 Martin Rudalics <rudalics@gmx.at>
790 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
791 current buffer (Bug#12387).
793 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
795 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
797 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
799 Use a more backwards-compatible timer format (Bug#12430).
800 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
801 vector element, not from the 4th, since PSECS is now at the end.
802 (Fcurrent_idle_time): Doc fix.
804 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
806 Function to mark objects and remove killed buffers at once.
807 * alloc.c (discard_killed_buffers): Rename to ...
808 (mark_discard_killed buffers) ... new name. Add marking
809 of remaining objects. Fix comment. Adjust users.
810 (mark_object): Do not touch frame buffer lists here.
811 * frame.c (delete_frame): Reset frame buffer lists here.
813 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
815 Better workaround for GNOME bug when --enable-gcc-warnings.
816 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
817 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
818 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
820 Simplify SIGIO usage (Bug#12408).
821 The code that dealt with SIGIO was crufty and confusing, e.g., it
822 played tricks like "#undef SIGIO" but these tricks were not used
823 consistently. Simplify mostly by not #undeffing standard symbols,
824 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
825 or not as we please) rather than "defined SIGIO" (standard symbol
826 that we probably shouldn't #undef).
827 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
828 Modules that need it can include it.
829 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
830 * dispextern.h (ignore_sigio): New decl.
831 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
832 unconditionally, since it's now a no-op if !USABLE_SIGIO.
833 * emacs.c (shut_down_emacs):
834 * keyboard.c (kbd_buffer_store_event_hold):
835 Use ignore_sigio rather than invoking 'signal' directly.
836 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
838 (FIONREAD, SIGIO): Do not #undef.
839 (tty_read_avail_input): Use #error rather than a syntax error.
840 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
841 for I_PIPE, used by SETUP_SLAVE_PTY.
842 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
843 * sysdep.c (croak): Remove; no longer needed. This bit of
844 temporary code, with Fred N. Fish's comment that it's temporary,
845 has been in Emacs since at least 1992!
846 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
847 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
848 * syssignal.h (croak): Remove decl.
849 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
850 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
851 now that we're termios-only.
852 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
853 * term.c (dissociate_if_controlling_tty): Use #error rather than
856 Work around GCC and GNOME bugs when --enable-gcc-warnings.
857 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
858 to work around GNOME bug 683906.
859 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
860 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
861 This works around GCC bug 54561.
863 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
865 More fixes for 'volatile' and setjmp/longjmp.
866 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
867 * image.c (struct png_load_context) [HAVE_PNG]: New type.
868 (png_load_body) [HAVE_PNG]:
869 (jpeg_load_body) [HAVE_JPEG]:
870 New function, with most of the old parent function's body.
871 (png_load) [HAVE_PNG]:
872 (jpeg_load) [HAVE_JPEG]:
873 Invoke the new function, to avoid longjmp munging our locals.
874 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
875 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
876 longjmp is passed 2, as the C standard doesn't guarantee this.
877 Instead, store the failure code into mgr->failure_code.
879 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
881 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
882 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
883 (syms_of_keyboard): Remove support for unread-command-char.
885 2012-09-12 Eli Zaretskii <eliz@gnu.org>
887 * w32proc.c (sys_kill): If PID is our process ID and the signal is
888 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
889 violation. (Bug#12426)
891 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
893 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
895 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
897 * eval.c: Add `inhibit-debugger'.
898 (Qinhibit_debugger): New symbol.
899 (call_debugger): Bind it instead of Qdebug_on_error.
900 (maybe_call_debugger): Test Vinhibit_debugger.
901 (syms_of_eval): Define inhibit-debugger.
902 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
903 (syms_of_xdisp): Remove inhibit-debug-on-message.
905 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
907 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
908 If a nonvolatile local variable is written before a _longjmp to
909 the frame containing the variable, and is read after the _longjmp,
910 the value read is indeterminate. Some local variables of type
911 'struct handler' and 'struct catchtag' are used in this way, so
912 mark each of their slots as volatile if the slot can be set before
913 _longjmp and read afterwards.
914 * lisp.h (struct handler): var and chosen_clause are now volatile.
915 (struct catchtag): val, next, and pdlcount are now volatile.
917 * bidi.c (bidi_push_it, bidi_pop_it):
918 * fns.c (copy_hash_table):
919 * image.c (define_image_type):
920 * keyboard.c (kbd_buffer_store_event_hold):
921 * process.c (Fprocess_send_eof):
922 * xfaces.c (x_create_gc) [HAVE_NS]:
923 * xgselect.c (xg_select):
924 Prefer assignment to memcpy when either will do.
926 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
927 Use pointer-to-a-pointer to simplify and avoid a NILP check each
928 time an item is removed. No need to mark this function 'inline';
929 the compiler knows better than we do.
931 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
933 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
934 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
935 to change_frame_size (Bug#12388).
936 (windowDidResize:): Pass YES to updateFrameSize.
938 * nsterm.h: Add delay parameter to updateFrameSize.
940 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
942 Discard killed buffers from deleted window and frame objects.
943 This reduces an amount of references to killed buffers and
944 helps GC to reclaim them faster.
945 * alloc.c (discard_killed_buffers): New function.
946 (mark_object): Use it for deleted windows and frames.
947 (mark_object): If symbol's value is set up for a killed buffer
948 or deleted frame, restore it's global binding.
949 * data.c (swap_in_global_binding): Add GC notice.
950 (swap_in_symval_forwarding): Use convenient set_blv_where.
951 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
952 * window.h: ... to here.
954 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
956 Convenient macro to check whether the buffer is live.
957 * buffer.h (BUFFER_LIVE_P): New macro.
958 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
959 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
961 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
963 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
964 composition cases (Bug#12364).
966 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
967 overhang of succeeding glyphs overlapping box cursor.
969 * w32term.c (x_draw_glyph_string): Likewise.
971 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
973 Simplify, document, and port floating-point (Bug#12381).
974 The porting part of this patch fixes bugs on non-IEEE platforms
975 with frexp, ldexp, logb.
976 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
978 * floatfns.c: Simplify discussion of functions that Emacs doesn't
979 support, by removing commented-out code and briefly listing the
980 C89 functions excluded. The commented-out stuff was confusing
981 maintenance, e.g., we thought we needed cbrt but it was commented out.
982 (logb): Remove decl; no longer needed.
983 (isfinite): New macro, if not already supplied.
984 (isnan): Don't replace any existing macro.
985 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
986 are present on all C89 platforms.
987 (Ffrexp): Do not special-case zero, as frexp does the right thing
989 (Flogb): Do not use logb, as it doesn't have the desired meaning
990 on hosts that use non-base-2 floating point. Instead, stick with
991 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
992 frexp, to avoid getting an unspecified result.
994 * xdisp.c (Qinhibit_debug_on_message): Now static.
996 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
998 * nsterm.m (ns_update_begin): Set clip path to whole view by using
999 NSBezierPath (Bug#12131).
1001 2012-09-10 Chong Yidong <cyd@gnu.org>
1003 * fns.c (Fdelq, Fdelete): Doc fix.
1005 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
1007 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
1008 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
1010 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
1012 * lisp.h (make_lisp_ptr): New macro to replace XSET.
1013 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
1016 2012-09-09 Eli Zaretskii <eliz@gnu.org>
1018 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
1019 left fringe if the window has a left margin. This avoids leaving
1020 traces of the cursor because its leftmost pixel is not drawn over.
1022 * dispnew.c (update_window_line): When the left margin area of a
1023 screen line is updated, set the redraw_fringe_bitmaps_p flag of
1024 that screen line. (Bug#12277)
1026 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
1028 Assume C89 or later for math functions (Bug#12381).
1029 This simplifies the code, and makes it a bit smaller and faster,
1030 and (most important) makes it easier to clean up signal handling
1031 since we can stop worring about floating-point exceptions in
1032 library code. That was a problem before C89, but the problem
1033 went away many years ago on all practical Emacs targets.
1034 * data.c, image.c, lread.c, print.c:
1035 Don't include <math.h>; no longer needed.
1036 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
1037 might be autoconfigured, as that never happens.
1039 * doprnt.c (DBL_MAX_10_EXP):
1040 * print.c (DBL_DIG):
1041 Remove. C89 or later always defines these.
1042 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
1043 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
1044 (arith_error, domain_error, domain_error2):
1045 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
1046 no longer needed -- we simply return what C returns. All uses removed.
1047 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
1049 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
1050 Remove. All uses expanded, as these macros are no longer used
1051 more than once and are now more trouble than they're worth.
1052 (Ftan): Use tan, not sin / cos.
1053 (Flogb): Assume C89 frexp.
1054 (fmod_float): Assume C89 fmod.
1055 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
1056 (init_floatfns): Remove. All uses removed.
1058 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
1060 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
1061 compositeToPoint for OSX < 10.6 (Bug#12390).
1063 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
1065 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
1066 This produces more-accurate results.
1068 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
1070 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
1071 changes (Bug#12088).
1073 2012-09-08 Chong Yidong <cyd@gnu.org>
1075 * syntax.c (Fstring_to_syntax): Doc fix.
1077 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
1079 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
1080 in the internal border.
1081 (x_set_window_size): Remove static variables and their usage.
1082 (ns_redraw_scroll_bars): Fix NSTRACE arg.
1083 (ns_after_update_window_line, ns_draw_fringe_bitmap):
1084 Remove fringe/internal border adjustment (Bug#11052).
1085 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
1086 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
1087 (ns_fix_rect_ibw): Remove.
1088 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
1089 (ns_dumpglyphs_box_or_relief): Ditto.
1090 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
1092 (ns_dumpglyphs_image): Ditto.
1093 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
1095 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
1096 their usage. Add fringe_extended_p and its use as in other terms.
1097 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
1098 scroll bar was removed.
1099 (updateFrameSize): New function.
1100 (windowDidResize): Move code to updateFrameSize and call it.
1102 * nsterm.h (EmacsView): Add updateFrameSize.
1104 2012-09-07 Chong Yidong <cyd@gnu.org>
1106 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
1108 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
1110 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
1112 More signal-handler cleanup (Bug#12327).
1113 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
1114 Problem introduced when merging patches. Noted by Eli Zaretskii in
1115 <http://bugs.gnu.org/12327#67>.
1116 * floatfns.c: Comment fix.
1117 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
1118 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
1119 and anyway the declaration is harmless even if SIGDANGER is not defined.
1120 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
1121 defined BROKEN_FIONREAD). systty.h formerly did this, but other
1122 source files not surprisingly expected syssignal.h to define, or
1123 not define, SIGIO, and it's cleaner to do it that way, for consistency.
1124 Include <sys/ioctl.h>, for FIONREAD.
1125 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
1126 This eliminates a problem whereby other files mysteriously had
1127 to include "syssignal.h" before including "systty.h" if they
1128 wanted to use "#ifdef SIGIO".
1130 2012-09-07 Eli Zaretskii <eliz@gnu.org>
1132 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
1134 * w32.c (sigemptyset): Empty the set.
1135 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
1137 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
1139 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
1141 * alloc.c (mark_buffer): Revert unsafe marking optimization.
1142 (mark_object): Likewise for frame objects.
1144 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
1146 * syssignal.h (handle_on_main_thread): Always declare,
1147 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
1148 This ports to platforms without HAVE_PTHREAD.
1150 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
1152 Signal-handler cleanup (Bug#12327).
1153 Emacs's signal handlers were written in the old 4.2BSD style with
1154 sigblock and sigmask and so forth, and this led to some
1155 inefficiencies and confusion. Rewrite these to use
1156 pthread_sigmask etc. without copying signal sets around. Also,
1157 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
1158 'signal', and instead use functions that do not attempt to take
1159 over the system name space. This patch causes Emacs's text
1160 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
1161 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
1162 Do not include <signal.h> or "syssignal.h", as these
1163 modules do not use signals.
1164 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
1165 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
1166 Do not include <signal.h>, as "syssignal.h" does that for us now.
1167 * atimer.c (sigmask_atimers): New function.
1168 (block_atimers, unblock_atimers): New functions,
1169 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
1171 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
1172 no longer needed here.
1173 * emacs.c (main): Inspect existing signal handler with sigaction,
1174 so that there's no need to block and unblock SIGHUP.
1175 * sysdep.c (struct save_signal): New member 'action', replacing
1176 old member 'handler'.
1177 (save_signal_handlers, restore_signal_handlers):
1178 Use sigaction instead of 'signal' to save and restore.
1179 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
1180 New function. All users of 'signal' modified to use set_sighandler
1181 if they're writeonly, and to use sys_signal if they're read+write.
1182 (emacs_sigaction_init, forwarded_signal): New functions.
1183 (sys_signal): Remove. All uses replaced by calls to sigaction
1184 and emacs_sigaction_init, or by direct calls to 'signal'.
1185 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
1186 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
1187 all uses replaced by pthread_sigmask etc. calls.
1188 * syssignal.h: Include <signal.h>.
1189 (emacs_sigaction_init, forwarded_signal): New decls.
1190 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
1191 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
1192 (sigmask, sys_sigmask): Remove; no longer needed.
1193 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
1194 (sigblock, sigunblock, sigfree):
1195 (sigsetmask) [!defined sigsetmask]:
1196 Remove. All uses replaced by pthread_sigmask.
1197 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
1198 no longer need to be replaced, and its typical old uses
1199 are now done via emacs_sigaction_init and sigaction.
1200 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
1201 (sys_sigdel): Remove; unused.
1202 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
1204 2012-09-06 Eli Zaretskii <eliz@gnu.org>
1206 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
1207 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
1209 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
1211 Explicitly mark buffer_defaults and buffer_local_symbols.
1212 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
1213 mark_local_symbols here.
1214 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
1215 since special buffers aren't marked here any more.
1216 (allocate_buffer): Chain new buffer with all_buffers here...
1217 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
1219 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
1220 (syms_of_buffer): Remove staticpro of the above.
1221 (init_buffer_once): Set names for buffer_defaults and
1222 buffer_local_symbols.
1224 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
1226 Use bool for booleans in font-related modules.
1227 * font.c (font_intern_prop, font_style_to_value)
1228 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
1229 (generate_otf_features, font_check_otf_features, font_check_otf)
1230 (font_match_p, font_list_entities, font_at):
1231 * fontset.c (fontset_id_valid_p, reorder_font_vector
1232 (fontset_find_font, Fset_fontset_font)
1233 (face_suitable_for_char_p) [0]:
1234 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
1235 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
1236 (m17n_flt_initialized, ftfont_shape_by_flt):
1237 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
1238 * nsfont.m (nsfont_draw):
1239 * w32font.c (w32font_draw):
1240 * w32term.c (x_draw_glyphless_glyph_string_foreground):
1241 Use bool for booleans.
1242 * font.h: Adjust to above API changes.
1243 (struct font, struct font_driver, struct font_driver_list):
1244 Use bool for booleans.
1245 (struct font): Remove useless member encoding_type.
1247 * fontset.c, xftfont.c: Omit unnecessary static decls.
1249 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
1251 * alloc.c (mark_object): Revert window marking code
1252 since it's unsafe for the Fset_window_configuration.
1254 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
1256 Fix race conditions with signal handlers and errno (Bug#12327).
1257 Be more systematic about preserving errno whenever a signal
1258 handler returns, even if it's not in the main thread. Do this by
1259 renaming signal handlers to distinguish between signal delivery
1260 and signal handling. All uses changed.
1261 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
1262 * data.c (deliver_arith_signal): Rename from arith_error.
1263 * dispnew.c (deliver_window_change_signal): Rename from
1264 window_change_signal.
1265 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
1266 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
1267 * keyboard.c (deliver_input_available_signal): Rename from
1268 input_available_signal.
1269 (deliver_user_signal): Rename from handle_user_signal.
1270 (deliver_interrupt_signal): Rename from interrupt_signal.
1271 * process.c (deliver_pipe_signal): Rename from send_process_trap.
1272 (deliver_child_signal): Rename from sigchld_handler.
1273 * atimer.c (handle_alarm_signal):
1274 * data.c (handle_arith_signal):
1275 * dispnew.c (handle_window_change_signal):
1276 * emacs.c (handle_fatal_signal, handle_danger_signal):
1277 * keyboard.c (handle_input_available_signal):
1278 * keyboard.c (handle_user_signal, handle_interrupt_signal):
1279 * process.c (handle_pipe_signal, handle_child_signal):
1280 New functions, with the actual signal-handling code taken from the
1281 original respective signal handlers, sans the sporadic attempts to
1282 preserve errno, since that's now done by handle_on_main_thread.
1283 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
1284 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
1285 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
1287 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
1288 Move initialization of main_thread to sysdep.c's init_signals.
1289 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
1290 our usage, and simplifies the mainline code.
1291 (record_child_status_change): New static function, as a helper
1292 for handle_child_signal, and with most of the old child handler's
1294 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
1295 (handle_child_signal): Use the above.
1296 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
1297 Moved here from emacs.c.
1298 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
1299 code moved here from emacs.c's main function.
1300 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
1301 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
1302 This lets callers save and restore errno properly.
1304 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
1306 Remove redundant or unused things here and there.
1307 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
1308 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
1309 * editfns.c (Fcompare_buffer_substrings): Likewise.
1310 * frame.h (struct terminal, struct font_driver_list):
1311 Remove redundant declarations.
1312 * window.h (Qleft, Qright): Likewise.
1314 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
1316 Do not mark objects from deleted buffers, windows and frames.
1317 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
1318 (mark_object): Likewise for windows and frames.
1320 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
1322 * alloc.c (valid_lisp_object_p): Treat killed buffers,
1323 buffer_defaults and buffer_local_symbols as valid objects.
1324 Return special value to denote them.
1326 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
1328 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
1329 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
1330 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
1331 (file_name_absolute_p, Fsubstitute_in_file_name):
1332 (check_executable, check_writable, Ffile_accessible_directory_p)
1333 (Fset_file_selinux_context, Fdefault_file_modes)
1334 (Finsert_file_contents, choose_write_coding_system)
1335 (Fwrite_region, build_annotations, a_write, e_write)
1337 * filelock.c (boot_time_initialized, get_boot_time)
1338 (get_boot_time_1, lock_file_1, within_one_second):
1339 * floatfns.c (in_float):
1340 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
1341 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
1342 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
1343 * lisp.h (struct Lisp_Hash_Table.cmpfn):
1344 * window.c (compare_window_configurations):
1345 Use bool for booleans.
1346 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
1347 (Fdefault_file_modes): Now mode_t, not int, for modes.
1348 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
1349 (internal_delete_file): Now returns void, not a (boolean) int,
1350 since nobody was looking at the return value.
1351 * lisp.h, window.h: Adjust to above API changes.
1353 * xdisp.c (set_message): Simplify and reindent last change.
1355 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
1357 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
1359 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
1361 * eval.c (call_debugger): Make the function non-static so that we
1362 can call it from set_message.
1364 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
1365 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
1367 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
1369 Give more-useful info on a fatal error (Bug#12328).
1370 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
1371 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
1372 of doing the work ourselves.
1373 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
1374 do most of the work.
1375 (fatal_error_backtrace): New function, taken from the guts
1376 of the old fatal_error_signal, but with a new option to output
1378 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
1379 info about the signal than just its number.
1380 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
1381 * sysdep.c: Include <execinfo.h>
1382 (emacs_backtrace): New function, taken partly from the previous
1383 code of the 'die' function.
1384 (emacs_abort): Call fatal_error_backtrace rather than abort.
1386 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
1388 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
1389 eager (load-time) macro-expansion.
1390 * lisp.mk (lisp): Add macroexp.
1392 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
1394 Simplify redefinition of 'abort' (Bug#12316).
1395 Do not try to redefine the 'abort' function. Instead, redo
1396 the code so that it calls 'emacs_abort' rather than 'abort'.
1397 This removes the need for the NO_ABORT configure-time macro
1398 and makes it easier to change the abort code to do a backtrace.
1399 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
1400 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
1401 Remove; sysdep.c's emacs_abort now takes its place.
1402 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
1403 'abort' changed to use 'emacs_abort'.
1404 * msdos.c (dos_abort) [defined abort]: Remove; not used.
1405 (abort) [!defined abort]: Rename to ...
1406 (emacs_abort): ... new name.
1407 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
1408 the place of the old 'abort' in emacs.c.
1409 * w32.c, w32fns.c (abort): Do not #undef.
1410 * w32.c (emacs_abort): Rename from w32_abort.
1412 2012-09-04 Eli Zaretskii <eliz@gnu.org>
1414 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
1415 offsets[j].dv, since the y axis of the screen coordinates points
1416 down, while the y axis of the font definition coordinates points
1417 up. This fixes display of Arabic diacritics such as KASRA and
1418 KASRATAN. (Bug#11860)
1420 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
1422 Be more systematic about _setjmp vs setjmp.
1423 * alloc.c (test_setjmp, mark_stack):
1424 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
1425 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
1426 (png_load, my_error_exit, jpeg_load):
1427 * process.c (send_process_trap, send_process):
1428 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
1429 The underscored versions are up to 30x faster on some hosts.
1430 Formerly, the code used setjmp+longjmp sometimes and
1431 _setjmp+_longjmp at other times, with no particular reason to
1432 prefer setjmp+longjmp.
1434 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
1436 Fix minor problem found by static checking.
1437 * buffer.c (Fdelete_all_overlays): Return nil.
1439 2012-09-03 Martin Rudalics <rudalics@gmx.at>
1441 * buffer.c (Fdelete_all_overlays): New function.
1443 2012-09-03 Chong Yidong <cyd@gnu.org>
1445 * gtkutil.c: Add extern decl for Qxft.
1447 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>

1463 EXCLUDE_SUBRS_P. All callers changed.
1464 * dispextern.h, lisp.h: Reflect above API changes.
1465 * firstfile.c (dummy): Use the address of 'main', whose signature
1466 won't change, instead of the address of 'initialize', whose
1467 signature just changed from int to bool.
1468 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
1469 * msdos.c (fatal_error_in_progress): ... from here.
1470 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
1472 (redisplay_internal, unwind_redisplay): Simply clear
1473 REDISPLAYING_P when unwinding, instead of saving its previous,
1474 always-false value and then restoring it.
1476 Clean up some extern decls.
1477 Mostly, this hoists extern decls out of .c files and into .h files.
1478 That way, we're more likely to catch errors if the interfaces change.
1479 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
1480 declare xg_mark_data.
1481 * dispextern.h (x_frame_parm_handlers):
1483 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)

1499 * xfont.c (x_clear_errors):
1500 * xterm.c (x_frame_parm_handlers):
1501 Remove now-redundant extern decls.
1502 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
1503 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
1505 * xfaces.c: Remove unnecessary static decls.
1506 * xterm.c (updating_frame): Remove decl of nonexistent object.
1508 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
1509 when building globals.h, as the objects that are not built on
1510 this host are not needed to compile C files on this host.
1512 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
1514 * gtkutil.h: Remove prototype for x_wm_set_size_hint.

1552 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
1554 * makefile.w32-in (CCL_H, W32FONT_H): New macros.

1562 2012-09-01 Eli Zaretskii <eliz@gnu.org>
1564 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
1565 more than one grapheme cluster passed to the shaper: compute the
1566 offset adjustment values separately for each cluster. (Bug#11860)
1568 * image.c: Restore mistakenly removed inclusion of w32.h. Without
1569 it, GCC doesn't see prototypes of w32_delayed_load, and complains
1570 about implicit conversions from integer to pointer.
1572 2012-09-01 Daniel Colascione <dancol@dancol.org>
1574 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
1575 system used too early.
1577 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
1579 Better seed support for (random).

1621 window-system headers.

1627 * gtkutil.h (xg_list_node_): Include xterm.h to pick up needed
1628 window system declarations.
1630 * frame.h: Move common functions here: set_frame_menubar,
1631 x_set_window_size, x_sync, x_get_focus_frame,
1632 x_set_mouse_position, x_set_mouse_pixel_position,
1633 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

1657 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
1659 Remove mark_ttys function and fix tty_display_info initialization.
1660 * lisp.h (mark_ttys): Remove prototype.
1661 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
1662 to mark_ttys because all possible values of 'top_frame' slot are
1663 the frames which are reachable from Vframe_list.
1664 * term.c (mark_ttys): Remove.
1665 (init_tty): Safely initialize 'top_frame' slot with Qnil.
1667 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>

1694 * lread.c (init_lread): For out-of-tree builds, only add the
1695 source directory's site-lisp dir to the load-path if it exists,
1696 consistent with in-tree builds. (Bug#12302)
1698 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>

1715 (timeout_handler:): Set timer_fired to YES.
1716 (runDialogAt:): Set timer_fired to NO.
1717 Handle click on close button as quit.
1719 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
1720 Add window_closed and button_values. Add void as return value for
1721 add(Button|String|Split). addButton takes int instead of Lisp_Object.
1722 Add process_dialog as new member.
1724 2012-08-28 Eli Zaretskii <eliz@gnu.org>
1726 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it

1829 Use bool for booleans.
1830 * dired.c (file_name_completion):
1831 * process.h (fd_callback):
1832 Omit int (actually boolean) argument. It wasn't being used.
1834 * composite.h, lisp.h: Reflect above API changes.
1836 * cmds.c, coding.c: Use bool for booleans.

1857 (Fset_coding_system_priority):
1858 * fileio.c (Finsert_file_contents):
1859 Use bool for booleans.
1860 * coding.h, lisp.h: Reflect above API changes.
1861 * coding.c: Remove unnecessary static function decls.
1862 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
1863 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
1864 not a boolean 'int', since callers never look at the return value.
1865 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
1866 * coding.h (decoding_buffer_size, encoding_buffer_size)
1867 (emacs_mule_string_char): Remove unused extern decls.
1868 (struct iso_2022_spec, struct coding_system):
1869 Use 'unsigned int : 1' for boolean fields, since there's more than one.
1870 (struct emacs_mule_spec): Remove unused field 'full_support'.
1871 All initializations removed.
1872 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
1874 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
1876 Fix spare memory change (Bug#12286).
1877 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
1878 (valid_lisp_object_p): Likewise.
1880 2012-08-27 Martin Rudalics <rudalics@gmx.at>
1882 * window.c (Fset_window_configuration): Record any window's old
1883 buffer if it's replaced (see Bug#8789). If the new current
1884 buffer doesn't appear in the selected window, go to its old
1887 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
1889 Special MEM_TYPE_SPARE to denote reserved memory.
1890 * alloc.c (enum mem_type): New memory type.
1891 (refill_memory_reserve): Use new type for spare memory.
1892 This prevents live_cons_p and live_string_p from incorrect
1893 detection of uninitialized objects from spare memory as live.
1895 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
1898 * Makefile.in (.PHONY): versioclean -> versionclean.
1900 Remove unused external symbols.
1901 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
1902 * window.c (Qwindow_valid_p, decode_valid_window):
1903 Now static, not extern.
1904 * data.c (Qinterval): Remove; unused.
1905 (syms_of_data): Do not define 'interval'.
1906 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
1907 * window.h (decode_valid_window):
1910 * character.c, charset.c, chartab.c: Use bool for booleans.

1920 (char_table_set_range, optimize_sub_char_table)
1921 (map_sub_char_table):
1922 Use bool for boolean.
1923 * character.c (str_to_unibyte): Omit last boolean argument; it was
1924 always 0. All callers changed.
1925 * character.h, charset.h: Adjust to match previous changes.
1926 * character.h (char_printable_p): Remove decl of nonexistent function.
1927 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
1928 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
1929 are all boolean, so make them single-bit bitfields.
1931 * lisp.h (ASET): Remove attempt to detect side effects.
1932 It was meant to be temporary and it often doesn't work,
1933 because when IDX has side effects the behavior of IDX==IDX
1934 is undefined. See Stefan Monnier in
1935 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
1937 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
1939 * lisp.h (functionp): New function (extracted from Ffunctionp).
1940 (FUNCTIONP): Use it.
1941 * eval.c (Ffunctionp): Use it.
1943 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
1945 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
1946 as that's faster and simpler than static storage. Don't bother
1947 with the g_main_context_query overhead if g_main_context_pending
1948 says no events are pending.
1949 (gfds, gfds_size): Remove these static vars.
1950 (xgselect_initialize): Remove; no longer needed.
1951 All uses and decls removed.
1953 * emacs.c (fatal_error_signal_hook): Remove.
1954 All uses removed. This leftover from old code was always 0.
1956 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
1957 * casefiddle.c (casify_object, casify_region):
1958 * casetab.c (set_case_table):
1959 * category.c, category.h (word_boundary_p):
1960 * category.h (CHAR_HAS_CATEGORY):
1961 Use bool for booleans, instead of int.
1963 2012-08-25 Eli Zaretskii <eliz@gnu.org>
1965 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
1967 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
1969 On assertion failure, print backtrace if available.
1970 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
1971 (die) [ENABLE_CHECKING]: Print a backtrace if available.
1972 * Makefile.in (LIB_EXECINFO): New macro.
1975 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
1976 * bytecode.c (exec_byte_code):
1977 * callint.c (check_mark, Fcall_interactively):
1978 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
1979 (getenv_internal, sync_process_alive, call_process_exited):
1980 * lisp.h (USE_SAFE_ALLOCA):
1981 Use bool for booleans, instead of int.
1982 * lisp.h, process.h: Adjust prototypes to match above changes.
1983 * callint.c (Fcall_interactively): Don't assume the mark's
1984 offset fits in 'int'.
1986 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
1988 * buffer.c, buffer.h: Use bool for boolean.
1989 * buffer.c (reset_buffer_local_variables)
1990 (buffer_lisp_local_variables, Fset_buffer_modified_p)
1991 (Frestore_buffer_modified_p, Fset_buffer_multibyte):

1993 (overlay_touches_p, overlay_strings, Foverlay_put)
1994 (report_overlay_modification, call_overlay_mod_hooks):
1995 (mmap_enlarge, mmap_set_vars):
1996 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
1997 Use bool for booleans, instead of int.
1998 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
1999 since the 1-or-0 return value is always ignored anyway.
2000 (mmap_initialized_p):
2001 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
2002 * buffer.h, lisp.h: Adjust prototypes to match above changes.
2004 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
2006 * bidi.c: Use bool for boolean.
2007 This is a bit more readable, and makes the text segment of bidi.o
2008 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
2009 Presumably it's faster too.
2010 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
2012 (bidi_cache_find_level_change, bidi_cache_iterator_state)
2013 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
2014 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
2015 (bidi_explicit_dir_char, bidi_level_of_next_char)
2016 (bidi_find_other_level_edge, bidi_move_to_visually_next):
2017 Use bool for booleans, instead of int.
2018 * dispextern.h (bidi_init_it, bidi_paragraph_init)
2019 (bidi_unshelve_cache): Adjust decls to match code.
2021 2012-08-23 Martin Rudalics <rudalics@gmx.at>
2023 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
2026 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
2028 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
2029 * atimer.h: Include <stdbool.h>.
2031 2012-08-22 Dan Nicolaescu <dann@gnu.org>
2033 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
2034 compile time tests instead of run time tests on systems that do
2036 (FRAME_MAC_P): Remove leftover from deleted code.
2037 * frame.c (syms_of_frame): Remove leftover from deleted code.
2039 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
2041 * nsterm.m (insertText:): Don't clear modifiers if code is space.
2043 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
2045 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
2046 Otherwise, the compiler complains about (A?B:C) where B is void
2047 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
2048 (fontset_add): Return void, for FONTSET_ADD.
2050 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
2052 * alloc.c: Use bool for booleans.
2053 (gc_in_progress, abort_on_gc)
2054 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
2055 (dont_register_blocks) [GC_MALLOC_CHECK]:
2056 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
2057 (check_string_bytes, make_specified_string, memory_full)
2058 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
2059 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
2060 (mark_stack, valid_pointer_p, make_pure_string)
2061 (Fgarbage_collect, survives_gc_p, gc_sweep):
2062 Use bool for booleans, instead of int.
2063 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
2064 Remove unused local.
2065 * alloc.c (PURE_POINTER_P):
2066 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
2067 * editfns.c (Fformat):
2068 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
2070 * fns.c (sweep_weak_table):
2071 * lisp.h (suppress_checking, push_message, survives_gc_p)
2072 (make_pure_string, gc_in_progress, abort_on_gc):
2073 * lread.c (readchar, read1):
2074 * print.c (Fprin1_to_string):
2075 * xdisp.c (push_message):
2076 Use bool for booleans affected directly or indirectly by
2079 Make recently-introduced setters macros.
2080 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
2081 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
2082 (set_fontset_default, set_fontset_fallback): Rename from their
2083 upper-case counterparts, and make them functions rather than macros.
2084 This is more consistent with the other recently-introduced setters.
2085 These don't need to be inline, since they're local.
2087 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
2089 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
2090 the loop (Bug#12247).
2092 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
2094 * lisp.h (vcopy): Use memcpy rather than our own loop.
2095 This fixes a performance regression introduced by the recent
2096 addition of vcopy. This means 'vcopy' will need to be modified
2097 for a copying collector, but that's OK. Also, tighten the
2098 checking in the assertion.
2100 2012-08-21 Eli Zaretskii <eliz@gnu.org>
2102 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
2103 components for RTL text (Bug#11860). Adjust X-OFFSET of each
2104 non-base glyph for the width of the base character, according to
2105 what x_draw_composite_glyph_string_foreground expects.
2106 Generate WADJUST value according to composition_gstring_width's
2107 expectations, to produce correct width of the composed character.
2108 Reverse the sign of the DU offset produced by ScriptPlace.
2110 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
2112 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
2114 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
2116 Avoid direct writes to contents member of struct Lisp_Vector.
2117 * lisp.h (vcopy): New function to copy data into vector.
2118 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
2119 * fns.c (Ffillarray): Use ASET.
2120 * keyboard.c (timer_check_2): Use AREF and ASET.
2121 (append_tool_bar_item, Frecent_keys): Use vcopy.
2122 * lread.c (read_vector): Use ASET.
2123 * msdos.c (Frecent_doskeys): Use vcopy.
2124 * xface.c (Finternal_copy_lisp_face): Use vcopy.
2125 (Finternal_merge_in_global_face): Use ASET and vcopy.
2126 * xfont.c (xfont_list_pattern): Likewise.
2128 2012-08-21 Martin Rudalics <rudalics@gmx.at>
2130 * window.c (Fwindow_point): For the selected window always return
2131 the position of its buffer's point.
2132 (Fset_window_point): For the selected window always go in its
2133 buffer to the specified position.
2135 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
2137 Setter macros for fontsets.
2138 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
2139 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
2140 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
2143 2012-08-20 Glenn Morris <rgm@gnu.org>
2145 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
2146 Don't assume that `ln -f' works.
2148 2012-08-20 Eli Zaretskii <eliz@gnu.org>
2150 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
2151 and later about non-assignments with no effect. See discussion at
2152 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
2155 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
2157 Inline setter functions for Lisp_Objects slots of struct specbinding.
2158 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
2161 2012-08-20 Martin Rudalics <rudalics@gmx.at>
2163 * window.c (select_window): Always make selected window's buffer
2166 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
2168 Use AREF and ASET for docstrings of category tables.
2169 * category.h (CATEGORY_DOCSTRING): Use AREF.
2170 (SET_CATEGORY_DOCSTRING): Use ASET.
2171 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
2173 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
2175 Inline setter functions for hash table members.
2176 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
2177 (set_hash_hash, set_hash_index): Rename with _slot suffix.
2178 (set_hash_key_and_value, set_hash_index, set_hash_next)
2179 (set_hash_hash): New functions.
2180 * charset.c, fns.c: Adjust users.
2182 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
2184 Inline getter and setter functions for per-buffer values.
2185 * buffer.h (per_buffer_default, set_per_buffer_default)
2186 (per_buffer_value, set_per_buffer_value): New functions.
2187 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
2188 * buffer.c, data.c: Adjust users.
2190 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
2192 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
2194 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
2196 Rely on <config.h> + <unistd.h> to declare 'environ',
2197 as gnulib does this if the system doesn't.
2198 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
2199 Remove declaration. MS-Windows declares it on stdlib.h which is
2200 included by conf_post.h.
2201 * emacs.c (environ) [DOUG_LEA_MALLOC]:
2202 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
2203 * vm-limit.c: Include <unistd.h>, for 'environ'.
2205 * unexaix.c, unexcoff.c: Include "mem-limits.h".
2206 (start_of_data): Remove decl; mem-limits.h provides it.
2208 * xdisp.c (handle_invisible_prop): Make it a bit faster
2209 and avoid a gcc -Wmaybe-uninitialized diagnostic.
2211 2012-08-19 Chong Yidong <cyd@gnu.org>
2213 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
2216 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
2218 * .gdbinit: Use call instead of set when calling a function in the
2221 * data.c (set_internal): Don't use set_blv_found.
2222 (Fkill_local_variable): Likewise.
2224 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
2226 * nsfont.m (ns_ascii_average_width): Ensure the string
2227 ascii_printable is initialized with a null-terminated character
2228 array. Otherwise, it can contain undesired extra characters.
2230 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
2232 port new setting code to Sun C 5.8 2005/10/13
2233 * chartab.c, lisp.h (char_table_set, char_table_set_range):
2234 Return void, not Lisp_Object. Otherwise, the compiler
2235 complains about (A?B:C) where B is void and C is Lisp_Object
2236 when compiling CHAR_TABLE_SET, due to the recent change to
2237 the API of sub_char_table_set_contents.
2239 2012-08-18 Chong Yidong <cyd@gnu.org>
2241 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
2242 for the string case (Bug#3874).
2244 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
2246 * buffer.h (BSET): Remove (Bug#12215).
2247 Replace all uses with calls to new setter functions.

3128 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
3129 more like a function. This is because the pointer cast is not
3130 needed. All uses changed.
3131 * print.c (print_string, print_error_message): Avoid length recalc.
3133 Improve fix for macroexp crash with debugging (Bug#12118).
3134 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
3135 ARRAY_MARK_FLAG when checking subscripts, because ASET is
3136 not supposed to be invoked from the garbage collector.
3137 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
3138 (gc_aset): New function, which is like ASET but can be
3139 used in the garbage collector.

3168 with addition of handling of symlinks and support for 'lstat'.
3169 If possible, get file's attributes and security information by
3170 handle, not by name. Produce S_IFLNK bit for symlinks, when
3171 called from 'lstat'.
3172 (stat, lstat): New functions, call 'stat_worker'.
3173 (symlink, readlink, careadlinkat): Rewritten to create and resolve
3174 symlinks when the underlying filesystem supports them.
3176 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
3178 Fix macroexp crash on Windows with debugging (Bug#12118).
3179 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
3180 checking subscripts; problem introduced with the recent
3181 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
3182 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
3183 since it's used in non-static inline functions now.
3185 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
3186 Don't assume buffer size fits in 'int'. Remove unused local.

3206 * composite.c (COMPOSITE_INLINE):
3207 * dispnew.c (DISPEXTERN_INLINE):
3208 * sysdep.c (SYSTIME_INLINE):
3209 Define to EXTERN_INLINE, so that the corresponding functions
3210 are compiled into code.

3212 (INLINE_HEADER_END): New macros.
3213 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

3235 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
3237 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
3238 This how ASET and AREF are supposed to work, and makes
3239 it easier to think about future improvements. See
3240 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
3241 * charset.h (set_charset_attr): New function.

3623 (w32_kbd_patch_key, key_event): Use the codepage returned by
3624 GetConsoleCP, rather than the ANSI codepage returned by GetLocaleInfo.

3656 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
3657 enumeration constants, as PURE and HEAP are too general, and clash
3658 with other headers and sources, such as gmalloc.c and the
3659 MS-Windows system headers. All users changed.
3661 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
3663 Revert last save_excursion_save and save_excursion_restore changes.
3664 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

3677 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
3678 arms of an 'if', not using conditional expressions; otherwise GDB
3679 complains about the types in the unevaluated arm when the argument
3680 is an integer literal.
3681 (xgetint): Simplify expression.
3682 * alloc.c (gdb_make_enums_visible): New constant. This ports to
3683 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
3684 Zaretskii in <http://bugs.gnu.org/12036#13>.
3685 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
3686 needed now that we have gdb_make_enums_visible.
3687 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
3688 (enum enum_USE_LSB_TAG):
3689 New enum types, packaging up enums that need to be exported to GDB.

3713 * lisp.h (struct Lisp_Excursion): New data type.
3714 (PVEC_EXCURSION): New pseudovector type.
3715 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
3716 to deal with it. Adjust comments.

3731 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
3732 emacs.c, as this is a more-suitable home. Had this been done earlier
3733 the fix for 12036 would have avoided some of the problems noted in
3734 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
3735 would have been more obvious.
3736 * emacs.c: Do not include <verify.h>; no longer needed.
3737 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
3738 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
3739 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
3740 Remove; now done in lisp.h.

3743 (DATA_SEG_BITS): Use it.
3744 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
3745 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
3746 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
3747 not be usable in #if. This simplifies things.
3749 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
3751 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.

3756 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
3757 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
3758 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
3759 Adjust to changes in lisp.h and emacs.c, by using
3760 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
3761 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
3762 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
3763 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
3764 instead of gdb_valbits.
3765 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
3766 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
3767 instead of gdb_array_mark_flag.
3768 (xboolvector): Get size from $->size, not $->header.size.
3769 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
3770 (xreload, hook-run, hookpost-run): Remove.
3771 * emacs.c: Include <verify.h>.
3772 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
3773 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
3775 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
3776 (gdb_USE_LSB_TAG): New enum constants.
3777 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
3778 Also define these as enum constants, so they're visible to GDB.
3779 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
3780 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
3781 as constants, so they're visible to GDB.

3784 Now enum constants, not macros, so they're visible to GDB.
3785 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
3786 more convenient now. All uses changed.
3787 (VALMASK) [USE_LSB_TAG]: Also define in this case.
3788 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
3790 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

3797 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
3798 add argument, tune behavior, and adjust all callers.
3800 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
3802 Use typedef for EMACS_INT, EMACS_UINT.
3803 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
3804 than macros. This simplifies debugging in the usual case, since
3805 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
3806 and it allows expressions involving EMACS_INT casts.
3807 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
3809 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

3819 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
3821 Adjust buffer text indirection counters at the end of Fkill_buffer.
3822 * buffer.c (Fkill_buffer): Adjust indirection counters when the
3823 buffer is definitely dead. This should really fix an issue reported
3824 by Christoph Scholtes again. (Bug#12007).
3825 (init_buffer_once): Initialize indirection counters of
3826 buffer_defaults and buffer_local_symbols (for sanity and safety).
3828 2012-07-24 Eli Zaretskii <eliz@gnu.org>
3830 * xdisp.c (init_iterator): Don't compute dimensions of truncation
3831 and continuation glyphs on tooltip frames, leave them at zero.

3857 (build_overlay): Add prototype.
3859 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
3861 Swap buffer text indirection counters in Fbuffer_swap_text.
3862 * buffer.c (Fbuffer_swap_text): Swap indirections too.
3863 This avoids crash reported by Christoph Scholtes at
3864 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
3866 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
3868 * nsmenu.m (Popdown_data): New struct.
3869 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
3871 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
3872 (initWithContentRect): Make imgView and contentView non-static
3873 and autorelease them. Also autorelease img and matrix (Bug#12005).
3874 (dealloc): Remove (Bug#12005).
3876 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
3878 Adjust consing_since_gc when objects are explicitly freed.

3891 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
3893 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
3894 as it's limited by the amount of memory, not by INT_MAX.
3896 2012-07-21 Eli Zaretskii <eliz@gnu.org>
3898 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
3899 in special-event-map. See the discussion at

3958 * font.c (font_open_by_name): Change 2nd and 3rd args to the only arg
3959 of type Lisp_Object to avoid redundant calls to make_unibyte_string.
3960 Adjust users accordingly.
3961 * font.h (font_open_by_name): Adjust prototype.

3980 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
3981 'for_each_per_buffer_object_at'.
3982 All uses changed. It's better to use upper-case for macros that

3984 that they're special.
3986 2012-07-19 Stefan Monnier <monnier@iro.umontreal.ca>
3988 * alloc.c (Fgarbage_collect): Tweak docstring.

4622 * s/aix4-2.h (unix): Remove; no longer needed.
4624 EMACS_TIME simplification (Bug#11875).
4625 This replaces macros (which typically do not work in GDB)
4626 with functions, typedefs and enums, making the code easier to debug.
4627 The functional style also makes code easier to read and maintain.
4628 * systime.h: Include <sys/time.h> on all hosts, not just if
4629 WINDOWSNT, since 'struct timeval' is needed in general.

4642 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
4643 not functions. All uses rewritten to use the following, respectively:
4644 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
4645 (add_emacs_time, sub_emacs_time): New functions.
4646 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
4647 * fileio.c (Fcopy_file):
4648 * xterm.c (XTflash): Get the current time closer to when it's used.
4649 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

4666 Prefer memcmp to strncmp when either will do.
4667 * nsterm.m: Include <ftoastr.h>.
4669 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
4670 Prefer snprintf to strncpy.
4671 * nsterm.m (ns_term_init):
4672 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
4673 * nsterm.m (ns_term_init):
4674 Avoid the need for strncpy, by using build_string or
4675 make_unibyte_string directly. Use dtoastr, not snprintf.
4676 * process.c (Fmake_network_process): Diagnose service names that
4677 are too long, rather than silently truncating them or creating
4678 non-null-terminated names.
4679 (Fnetwork_interface_info): Likewise, for interface names.
4680 * sysdep.c (system_process_attributes) [GNU_LINUX]:
4681 Prefer sprintf to strncat.

4688 Clarify fallback case.
4690 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>

4694 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
4695 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
4696 where argument type is known to be a Lisp_Cons.

4708 Optimize pure C strings initialization.
4709 * lisp.h (make_pure_string): Fix prototype.
4710 (build_pure_c_string): New function, defined as static inline. This
4711 provides a better opportunity to optimize away calls to strlen when
4712 the function is called with compile-time constant argument.
4713 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
4714 argument, adjust users accordingly. Use build_pure_c_string where

4717 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
4718 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.

4745 * s/gnu.h (DATA_START): Move definitions to configure.
4747 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
4748 We include usg5-4-common.h, which defines them both.
4750 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
4751 O_RDONLY already includes it).
4753 Stop ns builds setting the EMACSLOADPATH environment variable.
4754 * nsterm.m (ns_load_path): Rename from ns_init_paths.
4755 Now it does not set EMACSLOADPATH, just returns the load-path string.
4756 * nsterm.h: Update accordingly.
4757 * lread.c [HAVE_NS]: Include nsterm.h.
4758 (init_lread) [HAVE_NS]: Use ns_load_path.

4761 2012-07-09 Glenn Morris <rgm@gnu.org>
4763 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
4764 since the included bsd-common.h does so.
4766 Stop ns builds setting the EMACSPATH environment variable.
4767 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
4768 (ns_init_paths): Do not set EMACSPATH.
4769 * nsterm.h (ns_exec_path): Add it.
4770 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
4773 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
4775 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
4777 * process.c (wait_reading_process_output): 'waitchannels' was unset
4778 when read_kbd || !NILP (wait_for_cell); fix this.
4780 Add GCC-style 'const' attribute to functions that can use it.
4781 * character.h (char_resolve_modifier_mask):
4782 * keyboard.h (make_ctrl_char):
4783 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)

4794 Minor improvements to make_formatted_string.
4795 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
4796 where int is good enough, as vsprintf returns an int.
4797 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
4799 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>

4828 Move marker debugging code under MARKER_DEBUG.
4829 * marker.c (MARKER_DEBUG): Move marker debugging code under
4830 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
4831 for bootstrap with --enable-checking (~3x slowdown reported
4832 by Juanma Barranquero <lekktu@gmail.com>).
4833 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
4835 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
4837 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.

4842 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
4843 has no font, use the frame's font. (Bug#11813)
4844 (display_line): Add commentary about displaying truncation glyphs
4846 (produce_special_glyphs): Move here from term.c.
4848 * term.c (produce_special_glyphs): Move to xdisp.c.
4850 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
4853 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
4855 * xdisp.c (display_line): Avoid warning about implicit declaration
4858 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
4860 * lisp.h: Remove empty conditional.
4862 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
4864 * lread.c (load_path_check): Now static.
4866 Fix some minor --with-ns problems found by static checking.

4868 (x_set_font) [!HAVE_X_WINDOWS]:
4869 * image.c (xpm_load_image) [HAVE_NS]:
4870 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
4871 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
4872 Remove unused local.

4885 * lread.c (load_path_check): New function, split from init_lread.
4886 (init_lread): Reorganize. Motivation:
4887 If EMACSLOADPATH is set, check/warn about that rather than the
4888 defaults, which we are not going to use. Hence we can remove
4889 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
4890 Don't warn if site-lisp directories are missing.
4891 If not installed, start from a blank load-path, since
4892 PATH_LOADSEARCH refers to the eventual installation directories.

4903 GUI frame without a fringe to display continuation or truncation
4905 (insert_left_trunc_glyphs): Support GUI frames: make sure
4906 truncation glyphs overwrite enough glyphs from the current line to
4907 have sufficient space in pixels.
4908 (display_line): Support truncation and continuation glyphs on GUI
4909 frames. If some spare pixels are left on the line after inserting
4910 the truncation glyphs, fill that space with a stretch glyph of a
4911 suitably computed width.
4913 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
4914 produce_glyphs, to support GUI sessions.
4916 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
4918 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
4920 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
4922 Do not require float-time's arg to fit in time_t (Bug#11825).
4923 This works better on hosts where time_t is unsigned, and where
4924 float-time is applied to the (negative) difference between two times.
4925 * editfns.c (decode_time_components): Last arg is now double *,
4926 not int *, and means to store all the result as a double, without
4927 worrying about whether the seconds part fits in time_t.
4928 All callers changed.
4929 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
4930 All callers changed.
4931 (Ffloat_time): Do not fail merely because the specified time falls
4932 outside of time_t range.
4934 2012-07-07 Glenn Morris <rgm@gnu.org>
4936 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

4947 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
4949 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).

4951 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
4952 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
4953 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.

4956 * xfont.c (compare_font_names): Redo to omit the need for casts.
4958 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
4960 * xfns.c (Fx_change_window_property): Doc fix.
4961 * w32fns.c (Fx_change_window_property): Doc fix.
4963 * w32fns.c (Fx_window_property): Accept the same arguments as the
4964 X Windows version. Doc fix.
4965 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
4967 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
4968 Eli Zaretskii <eliz@gnu.org>
4970 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
4971 Windows-specific code from nt/config.nt moved here.
4972 Obsolete settings removed.
4974 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
4976 * process.c: Avoid unnecessary calls to gettime.
4977 (wait_reading_process_output): Don't get the time of day
4978 when gobbling data immediately and not waiting, as there's no need
4979 for it in that case. This removes a FIXME.
4981 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
4983 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
4984 is defined (Bug#11768).
4986 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4988 Fix marker debugging code.
4989 * marker.c (byte_char_debug_check): Do not perform the check
4990 if buffer is not multibyte.
4991 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
4992 Call byte_char_debug_check with correct arguments.
4994 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4996 Compile marker debugging code only if ENABLE_CHECKING is defined.
4997 * marker.c (byte_char_debug_check, count_markers):
4998 Use only if ENABLE_CHECKING is defined.
4999 (byte_debug_flag): Remove.
5000 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
5001 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
5003 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
5005 Avoid code repetition in marker-related functions.
5006 * marker.c (attach_marker): New function.
5007 (Fset_marker, set_marker_restricted, set_marker_both)
5008 (set_marker_restricted_both): Use it.
5009 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
5010 Consistently rename charno to charpos.
5011 (marker_position): Add eassert.
5012 (marker_byte_position): Convert to eassert.
5014 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

5024 * lisp.h (build_marker): New prototype.
5025 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
5026 * composite.c (autocmp_chars): Likewise.
5027 * editfns.c (buildmark): Remove.
5028 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
5029 (save_restriction_save): Use build_marker.
5030 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
5031 * window.c (save_window_save): Likewise.
5033 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
5035 Do not use Fdelete_overlay in delete_all_overlays
5036 to avoid redundant calls to unchain_overlay.
5037 * buffer.c (drop_overlay): New function.
5038 (delete_all_overlays, Fdelete_overlay): Use it.
5039 * minibuf.c (get_minibuffer): Fix comment.
5041 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
5043 Port to OpenBSD 5.1 amd64.
5044 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
5045 This is needed for OpenBSD, and should be harmless on all BSD systems.
5046 Also, include <sys/sysctl.h>, as it should be available on all
5047 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
5048 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
5049 use p_pid member, not kp_proc.pid.
5051 2012-07-06 Glenn Morris <rgm@gnu.org>
5053 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
5055 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
5057 More xmalloc and related cleanup.
5058 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:

5065 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
5066 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
5068 Omit needless casts involving void * pointers and allocation.
5069 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
5070 as the former is more robust if P's type is changed.
5071 Prefer xzalloc to xmalloc + memset 0.
5072 Simplify malloc-or-realloc to realloc.
5073 Don't worry about xmalloc returning a null pointer.
5074 Prefer xstrdup to xmalloc + strcpy.
5075 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
5077 * keyboard.c (apply_modifiers_uncached): Prefer local array to
5078 alloca of a constant.
5080 2012-07-05 Eli Zaretskii <eliz@gnu.org>
5082 * xdisp.c (display_line): Fix horizontal pixel coordinates when
5083 hscroll is larger than the line width. Fixes long and futile
5084 looping inside extend_face_to_end_of_line (on a TTY) producing
5085 glyphs that are not needed and thrown away.
5087 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
5089 * marker.c (set_marker_restricted_both): Simplify by using
5092 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>

5101 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
5102 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
5103 followed by gtk_box_set_homogeneous (Bug#11768).
5104 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
5105 (update_theme_scrollbar_width, xg_create_scroll_bar):
5106 Use gtk_scrollbar_new (Bug#11768).
5107 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
5108 (is_box_type): New function (Bug#11768).
5109 (xg_tool_item_stale_p): Call is_box_type.
5110 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
5111 with default display (Bug#11768).

5115 * xdisp.c (window_hscroll_limited): New function.
5116 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
5117 coordinates when window's hscroll is set to insanely large
5120 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
5122 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

5183 * fileio.c (time_error_value): Check the right error number.
5184 Problem reported by Troels Nielsen in
5185 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.

5189 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
5190 This should be fixed in a better way; see Eli Zaretskii in
5191 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
5192 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
5194 * fileio.c (time_error_value): Rename from special_mtime.
5195 The old name's problems were noted by Eli Zaretskii in
5196 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
5198 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
5199 This variable's comment says Emacs needs at least one GDB-visible
5200 symbol of type enum pvec_type, to work around GDB problems.
5201 The symbol's value doesn't matter.
5203 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
5204 that causes compilation to fail on pre-C99 compilers.
5206 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
5208 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

5221 (PSEUDOVECTOR_SIZE_BITS): New constant.
5222 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
5223 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
5224 change in pvec_type.
5225 (PSEUDOVECTOR_TYPEP): New macro.
5226 (TYPED_PSEUDOVECTORP): Use it.
5227 * fns.c (internal_equal): Adapt code to extract pvectype.
5228 * emacs.c (gdb_pvec_type): Update type.
5229 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
5230 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
5231 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
5232 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
5233 (sweep_vectors): Use it. Use local var `total_bytes' instead of
5234 abusing vector->header.next.nbytes.
5235 (live_vector_p): Use PVEC_TYPE.
5236 (mark_object): Adapt code to extract pvectype. Use switch.
5238 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
5240 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
5241 Tighten new eassert a bit.
5243 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
5245 Fix compilation with --enable-gcc-warnings and -O1
5247 * doprnt.c (doprnt): Change type of tem to int, initialize
5248 to avoid compiler warning. Add eassert.
5249 * search.c (simple_search): Initialize match_byte to avoid
5250 compiler warning. Add eassert.
5252 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
5254 Avoid weird behavior with large horizontal scrolls.
5255 Without this change, for example, large hscroll values would
5256 mess up Emacs's display on Fedora 15 x86, presumably due to
5257 overflows in int calculations in the display code.
5258 Also, if buffers had long lines, Emacs would freeze.
5259 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
5260 (set_window_hscroll): New function, containing the old guts of
5261 Fset_window_hscroll. Return the clipped value.
5262 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
5263 This avoids the need to check against PTRDIFF_MAX.
5265 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
5267 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>

5271 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
5273 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
5274 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
5275 since GCC 4.4.6 issues a bogus warning for them.
5277 Fix bugs in file timestamp newness comparisons.
5278 * fileio.c (Ffile_newer_than_file_p):
5279 * lread.c (Fload): Use full timestamp resolution of files,
5280 not just the 1-second resolution, so that files that are only
5281 slightly newer still count as newer.
5282 * fileio.c (Ffile_newer_than_file_p): Don't assume file
5283 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
5285 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
5287 * fileio.c: Improve handling of file time marker. (Bug#11852)
5288 (special_mtime): New function.
5289 (Finsert_file_contents, Fverify_visited_file_modtime):
5290 Use it to set special mtime values consistently.
5292 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
5294 * fileio.c (Finsert_file_contents): Properly handle st_mtime
5295 marker for non-existing file. (Bug#11852)
5297 2012-07-03 Glenn Morris <rgm@gnu.org>
5299 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
5300 and did not make it into globals.h).
5302 2012-07-03 Tom Tromey <tromey@redhat.com>

5340 2012-07-03 Glenn Morris <rgm@gnu.org>
5342 * lisp.h (Frandom): Make it visible to C.
5343 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
5344 buffer for invisible buffers. (Bug#1229)

5348 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
5349 values which aren't power of 2.
5350 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
5351 Verify it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
5354 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
5356 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.

5362 * alloc.c (allocate_vector_block): Remove redundant
5363 calls to mallopt if DOUG_LEA_MALLOC is defined.
5364 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
5365 avoid calls to mallopt if zero_vector is returned.
5367 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
5369 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
5370 is enabled, avoid dereferencing NULL current_sblock if
5373 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
5375 Cleanup basic buffer management.
5376 * buffer.h (struct buffer): Change layout to use generic vector
5377 marking code. Fix some comments. Change type of 'clip_changed'
5378 to bitfield. Remove unused #ifndef old.
5379 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
5380 (GET_OVERLAYS_AT): Fix indentation.
5381 (for_each_per_buffer_object_at): New macro.
5382 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
5383 (Fbuffer_local_variables): Use it.
5384 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
5385 * alloc.c (allocate_buffer): Adjust to match new layout of
5386 struct buffer. Fix comment.
5387 (mark_overlay): New function.
5388 (mark_buffer): Use it. Use mark_vectorlike to mark normal
5389 Lisp area of struct buffer.
5390 (mark_object): Use it. Adjust marking of misc objects
5391 and related comments.
5393 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
5395 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
5396 wrapper that is not needed because the wrapped code is a no-op (zero
5397 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
5398 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
5400 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
5402 * alloc.c (mark_buffer): Simplify. Remove prototype.
5403 (mark_object): Add comment. Reorganize marking of vector-like
5404 objects. Use CHECK_LIVE for all vector-like objects except buffers
5405 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
5406 Avoid redundant calls to mark_vectorlike for bool vectors.
5408 2012-06-30 Glenn Morris <rgm@gnu.org>
5410 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
5412 * epaths.in (PATH_SITELOADSEARCH): New.
5413 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
5414 This is rather than relying on --enable-locallisppath elements
5415 having "site-lisp" in their names. (Bug#10208#25, 11658)
5417 2012-06-30 Eli Zaretskii <eliz@gnu.org>
5419 * w32proc.c (sys_select): Accept and ignore one more argument.
5421 * w32.c (emacs_gnutls_pull): Call select with one more argument.
5423 * sysselect.h [DOS_NT]: Don't include sys/select.h.
5424 (pselect) [!MS_DOS]: Redirect to sys_select.
5426 * sysdep.c: Don't include dos.h and dosfns.h.
5428 * process.c (sys_select):
5429 * msdos.c (sys_select): Accept one more argument and ignore it.
5431 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
5432 adapt data types and code to that.
5435 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
5436 which clashes with the gnulib function of the same name.
5438 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
5440 * font.c (font_style_to_value, font_style_symbolic)
5441 (font_prop_validate_style): Add type checks for values in
5444 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
5446 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
5449 2012-06-29 Eli Zaretskii <eliz@gnu.org>
5451 * xdisp.c (try_window_id): Undo last change.
5453 * w32.c (getwd): Adjust commentary about startup_dir.
5454 (init_environment): Always call sys_access, even in non-MSVC
5455 builds. Don't chdir to the directory of the Emacs executable.
5456 This undoes code from 1997 which was justified by the need to
5457 "avoid conflicts when removing and renaming directories". But its
5458 downside was that every relative file name was being interpreted
5459 relative to the directory of the Emacs executable, which can never
5460 be TRT. In particular, it broke sys_access when called with
5461 relative file names.
5462 (sys_access): Map GetLastError to errno.
5464 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
5466 * window.h (struct window): Change type of 'fringes_outside_margins'
5467 to bitfield. Fix comment. Adjust users accordingly.
5468 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
5470 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
5473 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
5475 * gnutls.c (emacs_gnutls_handshake):
5476 Add QUIT to make the loop interruptible.
5478 2012-06-29 Glenn Morris <rgm@gnu.org>
5480 * charset.c (init_charset): Make lack of etc/charsets fatal.
5482 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
5484 * editfns.c (region_limit): Fix type mismatch.
5486 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
5488 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
5489 undefined. Convert from xassert to eassert.
5490 * nsmenu.m: Convert from xassert to eassert.
5491 * nsterm.m: Likewise.
5493 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
5495 * editfns.c (region_limit): Clip to narrowing (bug#11770).
5497 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
5499 Avoid integer overflow on scroll-left and scroll-right.
5500 * window.c (HSCROLL_MAX): New macro.
5501 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
5502 overflow when requested scroll falls outside ptrdiff_t range.
5504 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
5506 * window.h (struct window): Change type of 'hscroll',
5507 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
5508 'last_modified' and 'last_overlay_modified' to EMACS_INT.
5509 Adjust users accordingly.
5510 * xdisp.c (try_cursor_movement): Replace type check with eassert.
5511 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
5512 from EMACS_INT to ptrdiff_t.
5513 (make_window): Omit redundant initialization.
5515 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
5517 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
5519 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
5521 * window.h (struct window): Change type of 'use_time' and
5522 'sequence_number' from Lisp_Object to int.
5523 * frame.c (make_frame): Adjust users accordingly.
5524 * print.c (print_object): Likewise.
5525 * window.c (select_window, Fwindow_use_time, make_parent_window)
5526 (make_window): Likewise.
5528 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>

5531 enabled with --enable-checking=[all,glyphs] configure option.
5532 Fix GLYPH_DEBUG usage assuming that it may be undefined,
5533 adjust comments accordingly.
5534 * dispnew.c: Fix GLYPH_DEBUG usage assuming that it may be
5535 undefined, adjust comments accordingly.

5588 * alloc.c (allocate_string): Omit intervals initialization.
5589 * alloc.c (make_uninit_multibyte_string): Initialize intervals
5590 as in make_pure_string and make_pure_c_string.
5592 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
5594 * alloc.c (allocate_string): Fix last change.
5596 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>

5621 2012-06-26 Eli Zaretskii <eliz@gnu.org>
5623 * s/ms-w32.h (strcasecmp, strncasecmp) [_MSC_VER]: Redirect to
5624 _stricmp and _strnicmp.
5625 (HAVE_STRCASECMP, HAVE_STRNCASECMP): Define to 1.
5627 2012-06-26 Dmitry Antipov <dmantipov@yandex.ru>
5629 * alloc.c (allocate_window): Zero out non-Lisp part of newly
5631 (allocate_process): Likewise for new process.

5644 2012-06-26 Dmitry Antipov <dmantipov@yandex.ru>
5646 * alloc.c: Remove build_string.
5647 * lisp.h: Define build_string as static inline. This provides
5648 a better opportunity to optimize away calls to strlen when the
5649 function is called with compile-time constant argument.
5650 * image.c (imagemagick_error): Convert to build_string.
5651 * w32proc.c (sys_spawnve): Likewise.
5652 * xterm.c (x_term_init): Likewise.
5654 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
5656 Use sprintf return value instead of invoking strlen on result.
5657 In the old days this wasn't portable, since some sprintf
5658 implementations returned char *. But they died out years ago and
5659 Emacs already assumes sprintf returns int.
5660 Similarly for float_to_string.
5661 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
5662 * ccl.c (ccl_driver):
5663 * character.c (string_escape_byte8):
5664 * data.c (Fnumber_to_string):
5665 * doprnt.c (doprnt):
5666 * print.c (print_object):
5667 * xdisp.c (message_dolog):
5668 * xfns.c (syms_of_xfns):
5669 Use sprintf or float_to_string result to avoid need to call strlen.
5670 * data.c (Fnumber_to_string):
5671 Use make_unibyte_string, since the string must be ASCII.
5672 * lisp.h, print.c (float_to_string): Now returns int length.
5673 * term.c (produce_glyphless_glyph):
5674 Use sprintf result rather than recomputing it.
5676 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
5677 * Makefile.in (ALL_CFLAGS):
5678 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.
5679 * gmalloc.c, regex.c: Include <config.h> unconditionally.
5681 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
5683 * dispextern.h (xstrcasecmp): Define to library function
5684 strcasecmp if available.
5685 * xfaces.c: Do not use xstrcasecmp if strcasecmp is available.
5687 2012-06-25 Andreas Schwab <schwab@linux-m68k.org>
5689 * keyboard.c (menu_bar_items, menu_bar_item, read_key_sequence):
5690 Avoid comma operator.
5691 * menu.c (push_submenu_start, push_submenu_end)
5692 (push_left_right_boundary, push_menu_pane): Likewise.

5700 2012-06-25 Paul Eggert <eggert@cs.ucla.edu>
5702 * gtkutil.c (get_utf8_string): Remove redundant assignment.
5703 sprintf already null-terminates its output.
5705 * xfns.c (x_window): Remove redundant cast.
5707 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
5709 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
5710 `const char *' to `char *' to avoid compiler warning.
5712 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
5714 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
5715 instead of truncating it to 63 (admittedly a generous limit).
5717 * process.c: Fix spelling and caps in comments.
5719 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
5721 * emacs.c (setpgrp): Remove definition, unused.
5722 * sysdep.c (setpgrp): Remove definition, not used in this file.
5724 2012-06-24 Juanma Barranquero <lekktu@gmail.com>

5731 (SYSTIME_H): Add nt/inc/sys/time.h.
5733 * systime.h [WINDOWSNT]: Include sys/time.h.
5735 * s/ms-w32.h (struct timespec): Definition moved from
5736 nt/inc/sys/time.h. Suggested by Paul Eggert <eggert@cs.ucla.edu>.
5738 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
5740 Switch from NO_RETURN to C11's _Noreturn (Bug#11750).
5741 * buffer.h (buffer_slot_type_mismatch):
5742 * data.c (arith_error) [!FORWARD_SIGNAL_TO_MAIN_THREAD]:
5743 * eval.c (unwind_to_catch):

5762 * undo.c (user_error):
5763 * unexmacosx.c (unexec_error):
5764 * xterm.c (x_ins_del_lines, x_delete_glyphs):
5765 Use _Noreturn rather than NO_RETURN.
5766 No need for separate decl merely because of _Noreturn.
5767 * sound.c (sound_warning, parse_sound):
5768 Remove unnecessary forward decls.
5770 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
5772 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).
5773 * lisp.h (WAIT_READING_MAX): New macro.
5774 * dispnew.c (Fsleep_for, sit_for):
5775 * keyboard.c (kbd_buffer_get_event):
5776 * process.c (Faccept_process_output):
5777 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
5778 This improves on the previous patch, which introduced a bug
5779 when time_t is unsigned and as wide as intmax_t.
5780 See <http://bugs.gnu.org/9000#51>.
5782 2012-06-23 Eli Zaretskii <eliz@gnu.org>
5784 * dispnew.c (sit_for, Fsleep_for):
5785 * keyboard.c (kbd_buffer_get_event):
5786 * process.c (Faccept_process_output): Avoid compiler warnings when
5787 comparing a 32-bit time_t with a 64-bit INTMAX_MAX.
5789 2012-06-23 Juanma Barranquero <lekktu@gmail.com>
5791 * makefile.w32-in: Update dependencies.
5793 * w32.c (ltime): Add return type and declare static.
5794 (w32_get_internal_run_time): Remove usused variable `time_100ns'.
5796 2012-06-23 Paul Eggert <eggert@cs.ucla.edu>
5798 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
5799 Privately reported by Herbert J. Skuhra.
5800 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
5802 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
5803 not make_lisp_timeval, when the argument is of type EMACS_TIME.
5805 2012-06-23 Eli Zaretskii <eliz@gnu.org>
5807 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in
5808 last argument of make_unibyte_string.
5810 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
5811 language ID in the event parameters.
5813 * w32term.c (w32_read_socket): Put the new keyboard codepage into
5814 event.code, not the obscure "character set ID".
5816 2012-06-23 Chong Yidong <cyd@gnu.org>
5818 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.
5820 2012-06-23 Eli Zaretskii <eliz@gnu.org>
5822 Fix the MS-Windows build broken by 2012-06-22T21:17:42Z!eggert@cs.ucla.edu.
5823 * w32.c (fdutimens): New function.
5825 * w32proc.c (sys_select): Adapt to change in the EMACS_TIME type.
5827 * s/ms-w32.h (pselect): Redirect to sys_select.
5829 * sysselect.h [WINDOWSNT]: Don't include sys/select.h.
5831 * ralloc.c (r_alloc_inhibit_buffer_relocation): Fix stupid thinko
5832 in the logic of incrementing and decrementing the value of
5833 use_relocatable_buffers.
5835 2012-06-23 Paul Eggert <eggert@cs.ucla.edu>
5837 * sysdep.c [__FreeBSD__]: Fix recently-introduced typos.
5838 Privately reported by Herbert J. Skuhra.
5839 [__FreeBSD__]: Remove "*/" typo after "#include".
5840 (timeval_to_EMACS_TIME) [__FreeBSD__]: New static function.
5841 (TIMEVAL) [__FreeBSD__]: Now a static function rather than a macro.

5845 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
5847 Support higher-resolution time stamps (Bug#9000).
5848 The time stamps are only nanosecond-resolution at the C level,
5849 since that's the best that any real-world system supports now.
5850 But they are picosecond-resolution at the Lisp level, as that's
5851 easy, and leaves room for future OS improvements.
5853 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
5856 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
5857 Don't get current time unless it's needed.
5859 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
5860 now provides it if it's absent.
5861 (start_atimer): Port to higher-res time stamps.
5862 Check for time stamp overflow. Don't get current time more
5863 often than is needed.
5865 * buffer.h (struct buffer): Buffer modtime now has high resolution.
5866 Include systime.h, not time.h.
5867 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
5869 * dired.c: Include stat-time.h.
5870 (Ffile-attributes): File times now have higher resolution.
5872 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
5873 (struct image): Timestamp now has higher resolution.
5875 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
5876 has at least microseconds now. All uses removed.

5893 * fileio.c: Include <stat-time.h>
5894 (Fcopy_file): Copy higher-resolution time stamps.
5895 Prefer to set the time stamp via a file descriptor if that works.

5912 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
5913 Port to higher-resolution time stamps. Do not assume time_t is signed.
5914 (decode_timer): New function. Timers are now vectors of length 9,
5915 not 8, to accommodate the picosecond component.
5916 (timer_check_2): Use it.
5918 * nsterm.m (select_timeout, timeval_subtract): Remove.
5919 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
5920 as they're a bit more accurate and handle overflow better.
5921 (ns_select): Change prototype to be compatible with pselect.
5922 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
5923 * nsterm.h (ns_select): Adjust prototype.
5925 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
5926 us-resolution time stamps.
5927 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
5929 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
5931 * lisp.h (time_overflow): New decl.
5932 (wait_reading_process_output): First arg is now intmax_t, not int,
5933 to accommodate larger waits.
5935 * process.h (struct Lisp_Process.read_output_delay):

5942 (Faccept_process_output, wait_reading_process_output):
5943 Check for time stamp overflow. Do not assume time_t is signed.
5944 (select_wrapper): Remove; we now use pselect.
5945 (Fprocess_attributes): Now generates ns-resolution time stamps.
5947 * sysdep.c: Include utimens.h. Don't include utime.h
5948 or worry about struct utimbuf; gnulib does that for us now.
5949 (gettimeofday): Remove; gnulib provides a substitute.
5950 (make_timeval): New function.
5951 (set_file_times): Now sets ns-resolution time stamps.
5952 New arg FD; all uses changed.
5953 (time_from_jiffies, ltime_from_jiffies, get_up_time)

5955 Now returns ns-resolution time stamp. All uses changed.
5956 Check for time stamp overflow.
5958 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
5959 provides a substitute now.
5961 * systime.h: Include timespec.h rather than sys/time.h and time.h,
5962 since it guarantees struct timespec.
5963 (EMACS_TIME): Now struct timespec, so that we can support
5964 ns-resolution time stamps.
5965 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
5966 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
5967 (EMACS_USECS): Remove.
5968 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
5969 so multiply the arg by 1000 before storing it.
5970 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
5972 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):

5979 (make_timeval, make_lisp_time, decode_time_components): New decls.
5980 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
5981 that it mishandled time_t overflow. You can't compare by subtracting!
5982 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
5983 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.

5994 (w32_get_internal_run_time):
5995 Port to higher-resolution Emacs time stamps.

6006 * xselect.c (wait_for_property_change, x_get_foreign_selection):
6007 Check for time stamp overflow, and support ns-resolution time stamps.
6009 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
6010 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
6011 (timeval_subtract): Remove; no longer needed.
6012 (XTflash, XTring_bell, x_wait_for_event):
6013 Port to ns-resolution time stamps. Don't assume time_t is signed.

6019 2012-06-22 Eli Zaretskii <eliz@gnu.org>
6021 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
6022 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
6023 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
6024 staticidx goes up to 1597 out of 1600 = 0x640.)
6026 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
6028 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
6029 Otherwise, the umask might be mistakenly 0 while handling input signals.
6031 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
6033 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

6051 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
6053 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
6054 since tty frames can be explicitly named.

6062 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
6063 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
6064 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
6065 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.

6072 2012-06-18 Martin Rudalics <rudalics@gmx.at>
6074 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
6075 gets killed during executing of this function (Bug#11665).
6076 Try to always return Qt when the buffer has been actually killed.
6077 (Vkill_buffer_query_functions): In doc-string say that functions
6078 run by this hook should not change the current buffer.
6080 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
6082 Fix recently-introduced process.c problems found by static checking.
6083 * process.c (write_queue_push, write_queue_pop, send_process):

6100 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
6102 * lisp.h (eassert): Assume C89 or later.
6103 This removes the need for CHECK.
6104 (CHECK): Remove. Its comments about always evaluating its
6105 argument were confusing, as 'eassert' typically does not evaluate
6108 * coding.c (produce_chars): Use ptrdiff_t, not int.
6110 * xterm.c (x_draw_underwave): Check for integer overflow.
6111 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

6204 * xdisp.c (set_cursor_from_row): Don't dereference glyphs_end.
6205 If all the glyphs of the glyph row came from strings, and we have no
6206 cursor positioning clues, put the cursor on the first glyph of the

6299 Use an inline function on all platforms when using the union type,
6300 since this is simpler and 'static inline' can be used portably

6442 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
6444 * doprnt.c (doprnt): Truncate multibyte char correctly.
6445 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
6446 would mishandle a string argument "Xc" if X was a multibyte
6447 character of length 2: it would truncate after X's first byte
6448 rather than including all of X.
6450 2012-06-06 Chong Yidong <cyd@gnu.org>
6452 * buffer.c (word_wrap): Doc fix.

6501 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
6502 Convert pctcpu and pctmem to Lisp float properly.
6503 Let the compiler fold better, as 100.0/0x8000 is exact.
6505 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
6507 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
6510 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
6512 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
6514 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
6516 For a 'struct window', replace some Lisp_Object fields to
6517 bitfields where appropriate, remove unused fields.
6518 * window.h (struct window): Remove unused 'last_mark_x' and
6519 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
6520 change it's type from Lisp_Object to bitfield.
6521 Change type of 'force_start', 'optional_new_start',
6522 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
6523 fields from Lisp_Object to bitfield. Adjust users accordingly.
6525 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
6527 Pacify gcc -Wdouble-precision when using Xaw.

6529 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
6530 Use 'float' consistently, rather than 'float' in most places
6531 and 'double' in a couple of places.
6533 2012-05-31 Eli Zaretskii <eliz@gnu.org>
6535 * xdisp.c (handle_stop): Detect whether we have overlay strings
6536 loaded by testing it->current.overlay_string_index to be
6537 non-negative, instead of checking whether n_overlay_strings is
6538 positive. (Bug#11587)
6540 2012-05-31 Chong Yidong <cyd@gnu.org>
6542 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
6544 * doc.c (Fsubstitute_command_keys): Doc fix.
6546 2012-05-31 Eli Zaretskii <eliz@gnu.org>
6548 * search.c (search_buffer): Remove calls to
6549 r_alloc_inhibit_buffer_relocation, as it is now called by
6550 maybe_unify_char, which was the cause of relocation of buffer text
6553 2012-05-31 Eli Zaretskii <eliz@gnu.org>
6555 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
6556 for the duration of call to load_charset, to avoid problems with
6557 callers of maybe_unify_char that access buffer text through C
6560 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
6561 decrement the inhibition flag, instead of just setting or
6564 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
6566 Remove obsolete '#define static' cruft.
6567 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
6568 This #undef was "temporary" in 2000; it is no longer needed
6569 now that '#define static' has gone away.
6570 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
6571 (gray_bitmap_bits): Remove; no longer needed.
6572 All uses replaced with definiens.
6573 * xterm.c: Include "bitmaps/gray.xbm".
6575 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
6577 Clean up __executable_start, monstartup when --enable-profiling.
6578 The following changes affect the code only when profiling.
6579 * dispnew.c (__executable_start): Rename from safe_bcopy.
6580 Define only on platforms that need it.
6581 * emacs.c: Include <sys/gmon.h> when profiling.
6582 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
6583 (__executable_start): Remove decl, since lisp.h does it now.
6584 (safe_bcopy): Remove decl; no longer has that name.
6585 (main): Coalesce #if into single bit of code, for simplicity.
6586 Cast pointers to uintptr_t, since standard libraries want integers

6615 Do not create empty overlays with the evaporate property (Bug#9642).
6616 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
6617 Bug#9642, but explicitly check that the buffer the overlay would
6618 be moved to is live and rearrange lines to make sure that errors
6619 will not put the overlay in an inconsistent state.
6620 (Fdelete_overlay): Cosmetics.
6622 2012-05-28 Eli Zaretskii <eliz@gnu.org>
6624 * w32term.c (my_bring_window_to_top): New function.
6625 (x_raise_frame): Use handle returned by DeferWindowPos, which
6626 could be different from the original one.

6630 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
6631 by calling BringWindowToTop.
6633 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
6634 (WM_EMACS_END): Increase by one.
6636 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
6638 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
6639 This avoids undefined behavior that might cause the eassert
6640 to not catch an out-of-range value.
6642 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
6644 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

6654 when referring to sectname field in printf format.
6656 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
6658 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
6659 Only r_alloc_inhibit_buffer_relocation needed to be added;
6660 the others were already declared.
6662 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
6663 before checking whether it's out of range. Put the check inside
6665 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
6667 2012-05-27 Ken Brown <kbrown@cornell.edu>
6669 * callproc.c (Fcall_process): Restore a line that was accidentally
6670 commented out in the 2011-02-13 change (bug#11547).

6675 defined on ralloc.c.
6677 * buffer.c [REL_ALLOC]: Remove prototypes of

6679 they are now on lisp.h.
6681 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
6683 * search.c (search_buffer): Use it to inhibit relocation of buffer
6684 text while re_search_2 is doing its job, because re_search_2 is
6685 passed C pointers to buffer text. (Bug#11519)
6687 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
6690 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
6691 state after an additional call to move_it_in_display_line_to, keep
6692 the values of it->max_ascent and it->max_descent found for the
6694 (pos_visible_p): Revert the comparison against bottom_y to what it
6695 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
6698 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
6700 Fix coding-related core dumps with gcc -ftrapv.
6701 The code was computing A - B, where A and B are pointers, and B is
6702 random garbage. This can lead to core dumps on platforms that
6703 have special pointer registers, and it also leads to core dumps on
6704 x86-64 when compiled with gcc -ftrapv. The fix is to compute
6705 A - B only when B is initialized properly.
6706 * coding.c (coding_set_source, coding_set_destination): Return void.
6707 (coding_change_source, coding_change_destinations): New functions,
6708 with the old behaviors of coding_set_source and coding_set_destination.
6709 All callers that need an offset changed to use these new functions.
6711 2012-05-26 Glenn Morris <rgm@gnu.org>
6713 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
6715 2012-05-26 Eli Zaretskii <eliz@gnu.org>

6718 * xdisp.c (draw_row_with_mouse_face):
6719 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
6721 * w32console.c: Include window.h.
6722 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
6724 (initialize_w32_display): Initialize mouse-highlight data.
6726 * w32inevt.c: Include termchar.h and window.h.
6727 (do_mouse_event): Support mouse-autoselect-window. When the mouse
6728 moves, call note_mouse_highlight. If help_echo changed, call
6729 gen_help_event to produce help-echo message in the echo area.
6730 Call clear_mouse_face if mouse_face_hidden is set in the mouse
6733 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
6735 * lread.c (read1): Simplify slightly to avoid an overflow warning
6736 with GCC 4.7.0 on x86-64.
6738 2012-05-26 Eli Zaretskii <eliz@gnu.org>
6740 * bidi.c (bidi_mirror_char): Revert last change: an int is
6741 definitely wide enough here.
6743 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
6745 Fix integer width and related bugs (Bug#9874).

6753 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
6755 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6756 (allocate_pseudovector):
6757 Use int, not EMACS_INT, where int is wide enough.
6758 (inhibit_garbage_collection, Fgarbage_collect):
6759 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
6760 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
6761 int might not be wide enough.
6762 (bidi_cache_search, bidi_cache_find, bidi_init_it)
6763 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
6764 (bidi_at_paragraph_end, bidi_find_paragraph_start)
6765 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
6766 (bidi_level_of_next_char, bidi_move_to_visually_next):
6767 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6768 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
6769 (Fkill_buffer, Fset_buffer_major_mode)
6770 (advance_to_char_boundary, Fbuffer_swap_text)
6771 (Fset_buffer_multibyte, overlays_at, overlays_in)
6772 (overlay_touches_p, struct sortvec, record_overlay_string)
6773 (overlay_strings, recenter_overlay_lists)
6774 (adjust_overlays_for_insert, adjust_overlays_for_delete)
6775 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)

6777 (Foverlay_recenter, last_overlay_modification_hooks_used)
6778 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
6779 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6780 (validate_region): Omit unnecessary test for b <= e,
6781 since that's guaranteed by the previous test.
6782 (adjust_overlays_for_delete): Avoid pos + length overflow.
6783 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
6784 (report_overlay_modification):
6785 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
6786 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
6787 Omit pointer cast, which isn't needed anyway, and doesn't work
6788 after the EMACS_INT -> ptrdiff_t change.
6789 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
6790 * buffer.h: Adjust decls to match defn changes elsewhere.
6791 (struct buffer_text, struct buffer):
6792 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6793 Use EMACS_INT, not int, where int might not be wide enough.
6794 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
6795 not int, to avoid needless 32-bit limit on 64-bit hosts.
6796 (exec_byte_code): Use tighter memory-full test, one that checks
6797 for alloca overflow. Don't compute the address of the object just
6798 before an array, as that's not portable. Use EMACS_INT, not

6818 * category.h (CATEGORYP): Don't assume arg is nonnegative.
6819 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
6820 integers are now checked earlier. All uses replaced with XINT.
6822 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6823 For CCL_MapSingle, check that content and value are in int range.

6825 Check that Vcode_version_map_vector is a vector.
6826 (resolve_symbol_ccl_program): Check that vector header is in range.
6827 Always copy the vector, so that we can check its contents reliably
6828 now rather than having to recheck each instruction as it's being
6829 executed. Check that vector words fit in 'int'.
6830 (ccl_get_compiled_code, Fregister_ccl_program)
6831 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
6832 program indexes, to avoid needless 32-bit limit on 64-bit hosts.

6863 to be a character. Avoid int overflow if max_char is close

6866 this is intended anyway and avoids some undefined behavior.

6869 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.

6877 * chartab.c (Fmake_char_table, Fset_char_table_range)
6878 (uniprop_get_decoder, uniprop_get_encoder):
6879 Don't assume fixnum fits in int.
6880 * cmds.c (move_point): New function, that does the gist of
6881 Fforward_char and Fbackward_char, but does so while checking
6882 for integer overflow more accurately.

7504 Use SAFE_ALLOCA_LISP, not alloca.
7505 (merge_face_heights): Remove unnecessary cast to EMACS_INT.

7507 (face_at_buffer_position, face_for_overlay_string)
7508 (face_at_string_position):
7509 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
7510 (merge_faces): Use int, not EMACS_INT, where int is wide enough.
7511 * xfns.c (x_set_menu_bar_lines, x_set_tool_bar_lines, x_icon_verify)
7513 Check that fixnums are in proper range for system types.
7514 (Fx_create_frame, x_create_tip_frame, Fx_show_tip)

7527 (x_get_local_selection, x_reply_selection_request)
7528 (x_handle_selection_request, wait_for_property_change):
7529 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
7530 (selection_data_to_lisp_data): Use short, not EMACS_INT, where
7531 short is wide enough.
7532 (x_send_client_event): Don't assume fixnum fits in int.
7533 * xterm.c (x_x_to_emacs_modifiers):
7534 Don't assume EMACS_INT overflows nicely into int.
7535 (x_emacs_to_x_modifiers): Use EMACS_INT, not int, because values
7537 (handle_one_xevent): NATNUMP can eval its arg twice.
7538 (x_connection_closed):
7539 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
7540 * xterm.h: Adjust decls to match defn changes elsewhere.
7541 (struct scroll_bar): Use struct vectorlike_header
7542 rather than rolling our own approximation.
7543 (SCROLL_BAR_VEC_SIZE): Remove; not used.
7545 2012-05-25 Glenn Morris <rgm@gnu.org>
7547 * lisp.mk (lisp): Update for more files being compiled now.
7549 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>

7552 (read_pure): Remove var.
7553 (unreadpure): Remove function.
7554 (readevalloop): Don't call read_list with -1 flag.
7555 (read1, read_vector): Don't test read_pure any more.
7556 (read_list): Simplify.
7558 * fileio.c, character.h: Minor style tweaks.
7560 2012-05-24 Dmitry Antipov <dmantipov@yandex.ru>
7562 * window.h (clip_changed): Remove useless declaration.
7564 2012-05-22 Juanma Barranquero <lekktu@gmail.com>

7567 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
7569 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
7572 This directory predates autoconf and is no longer needed nowadays.
7573 Move its few remaining bits of functionality to where they're needed.
7574 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:
7575 * m/ibms390x.h, m/intel386.h, m/m68k.h, m/macppc.h, m/sparc.h:

7579 * lisp.h (USE_LSB_TAG):
7580 * mem-limits.h (EXCEEDS_LISP_PTR):
7581 Use VAL_MAX, not VALBITS, in #if.
7582 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
7583 (EMACS_UINT): Define unconditionally now.
7584 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
7585 (BITS_PER_EMACS_INT): New constants, replacing
7586 what used to be in config.h, but not useful in #if.
7587 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
7588 define them any more.
7589 (VAL_MAX): New macro.
7591 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
7592 BITS_PER_EMACS_INT, in #if.
7593 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
7594 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
7595 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
7596 * s/ms-w32.h (DATA_START):
7597 Move here from removed file m/intel386.h.
7598 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
7599 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
7601 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
7603 Assume C89 or later.
7604 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.

7611 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
7612 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
7613 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
7614 * xterm.c (input_signal_count): Assume volatile works.
7616 2012-05-21 Ken Brown <kbrown@cornell.edu>
7618 * xgselect.c (xg_select): Fix first argument in call to 'select'
7621 2012-05-20 Ken Brown <kbrown@cornell.edu>
7623 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
7624 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
7626 2012-05-19 Ken Brown <kbrown@cornell.edu>
7628 * xfns.c (x_in_use): Remove `static' qualifier.
7629 * xterm.h (x_in_use): Declare.
7630 * xgselect.c: Include xterm.h.
7631 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
7632 and `display_arg' (bug#9754).
7634 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
7636 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
7638 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
7639 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
7641 2012-05-18 Eli Zaretskii <eliz@gnu.org>
7643 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
7645 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
7646 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
7648 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
7649 reference to image_cache->refcount.
7650 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
7652 2012-05-17 Juri Linkov <juri@jurta.org>
7654 * search.c (Fword_search_regexp, Fword_search_backward)
7655 (Fword_search_forward, Fword_search_backward_lax)
7656 (Fword_search_forward_lax): Move functions to isearch.el
7657 (bug#10145, bug#11381).
7659 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
7661 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
7663 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
7665 * lread.c (init_obarray): Declare Qt and Qnil as special.
7667 2012-05-14 Glenn Morris <rgm@gnu.org>
7669 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
7670 Put "libexec" before "bin", for the sake of init_callproc_1.
7672 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
7674 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
7676 * unexaix.c: Port to more-recent AIX compilers.
7677 (report_error, report_error_1, make_hdr, copy_sym)
7678 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
7679 Make arguments const char *, not char *, to avoid violations of C
7680 standard and to fix some AIX warnings reported by Gilles Pion.
7682 2012-05-14 Eli Zaretskii <eliz@gnu.org>
7684 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
7685 already have overlays loaded.
7686 (handle_single_display_spec): Before returning without displaying
7687 fringe bitmap, synchronize the bidi iterator with the main display
7688 iterator, by calling iterate_out_of_display_property.
7689 (iterate_out_of_display_property): Detect buffer iteration by
7690 testing that it->string is a Lisp string.
7691 (get_next_display_element): When the current object is exhausted,
7692 and there's something on it->stack, call set_iterator_to_next to
7693 proceed with what's on the stack, instead of returning zero.
7694 (set_iterator_to_next): If called at the end of a Lisp string,
7695 proceed to consider_string_end without incrementing string
7696 position. Don't increment display vector index past the end of
7697 the display vector. (Bug#11417)
7698 (pos_visible_p): Don't report a position visible when move_it_to
7699 stopped at the last line of window, which happens to be scanned
7700 backwards by the bidi iteration. (Bug#11464)
7702 2012-05-14 Eli Zaretskii <eliz@gnu.org>
7704 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
7705 and right-margin display specs even if the spec is invalid or we
7706 are on a TTY, and thus unable to display on the fringes.
7707 That's because the text with the property will not be displayed anyway,
7708 so we need to signal to the caller that this is a "replacing"
7709 display spec. This fixes display when the spec is invalid or we
7712 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
7714 * unexaix.c (make_hdr): Fix typo in prototype.
7715 This bug broke the build on AIX. Problem reported by Gilles Pion.
7717 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
7719 * keyboard.c (kbd_buffer_get_event): Read special events also in
7720 batch mode. (Bug#11415)
7722 2012-05-12 Glenn Morris <rgm@gnu.org>
7724 * ns.mk: Update for ns_appbindir no longer having trailing "/".
7726 2012-05-12 Eli Zaretskii <eliz@gnu.org>
7728 * lisp.mk (lisp): Add newcomment.elc.
7730 2012-05-12 Glenn Morris <rgm@gnu.org>
7732 * Makefile.in (MKDIR_P): New, set by configure.
7733 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
7735 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
7737 Remove unused function hourglass_started.
7738 * dispextern.h (hourglass_started):
7739 * w32fns.c (hourglass_started):
7740 * xdisp.c (hourglass_started): Remove.
7742 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
7744 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
7745 Update dependencies.
7747 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
7749 * xgselect.c (xg_select): Put maxfds+1 into a var.
7750 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
7752 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
7754 2012-05-10 Dave Abrahams <dave@boostpro.com>
7756 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
7757 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
7759 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
7761 * dbusbind.c (xd_registered_buses): New internal Lisp object.
7762 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
7763 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
7764 Initialize xd_registered_buses.
7766 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
7768 Untag more efficiently if USE_LSB_TAG.
7769 This is based on a proposal by YAMAMOTO Mitsuharu in
7770 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
7771 For an admittedly artificial (nth 8000 longlist) benchmark on
7772 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
7773 Emacs's overall text size by 1%.
7774 * lisp.h (XUNTAG): New macro.
7775 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
7776 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
7777 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
7778 * eval.c (Fautoload):
7779 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
7780 * frame.h (XFRAME): Use XUNTAG.
7782 Port recent dbusbind.c changes to 32-bit --with-wide-int.
7783 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
7784 Remove unportable assumptions about print widths of types like
7786 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
7787 intptr_t when converting between pointer and integer, to avoid GCC
7788 warnings about wrong width.
7790 2012-05-09 Eli Zaretskii <eliz@gnu.org>
7792 * w32proc.c (new_child): Force Windows to reserve only 64KB of
7793 stack for each reader_thread, instead of defaulting to 8MB
7794 determined by the linker. This avoids failures in creating
7795 subprocesses on Windows 7, see the discussion in this thread:
7796 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
7798 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
7800 Fix up display of the *Minibuf-0* buffer in the mini window.
7801 * keyboard.c (read_char): Don't clear the echo area if there's no
7803 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
7804 contents of *Minibuf-0*) if there's no message displayed in its stead.
7806 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
7808 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
7811 2012-05-06 Chong Yidong <cyd@gnu.org>
7813 * lisp.mk (lisp): Update.
7815 2012-05-05 Jim Meyering <meyering@redhat.com>
7817 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
7819 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
7821 * data.c (PUT_ERROR): New macro.
7822 (syms_of_data): Use it. Add new error type `user-error'.
7823 * undo.c (user_error): New function.
7824 (Fprimitive_undo): Use it.
7825 * print.c (print_error_message): Adjust print style for `user-error'.
7826 * keyboard.c (user_error): New function.
7827 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
7829 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
7831 Do not limit current-time-string to years 1000..9999.
7832 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
7833 (Fcurrent_time_string): Support any year that is supported by the
7834 underlying localtime representation. Don't use asctime, as it
7835 has undefined behavior for years outside the range -999..9999.
7837 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
7839 Fix race conditions involving setenv, gmtime, localtime, asctime.
7840 Without this fix, interrupts could mess up code that uses these
7841 nonreentrant functions, since setting TZ invalidates existing
7842 tm_zone or tzname values, and since most of these functions return
7843 pointers to static storage.
7844 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
7845 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
7846 Grow the critical sections to include not just invoking
7847 localtime/gmtime, but also accessing these functions' results
7848 including their tm_zone values if any, and any related TZ setting.
7849 (format_time_string): Last arg is now struct tm *, not struct tm **,
7850 so that the struct tm is saved in the critical section.
7851 All callers changed. Simplify allocation of initial buffer, partly
7852 motivated by the fact that memory allocation needs to be outside
7853 the critical section.
7855 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
7857 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
7858 with RESET_INTERVAL.
7860 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
7861 Remove duplicated buffer name initialization.
7863 2012-05-02 Jim Meyering <jim@meyering.net>
7865 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
7867 * xfns.c (x_window): Use xstrdup (Bug#11375).
7869 2012-05-02 Eli Zaretskii <eliz@gnu.org>
7871 * xdisp.c (pos_visible_p): If already at a newline from the
7872 display string before the 'while' loop, don't walk back the glyphs
7873 from it3.glyph_row. Solves assertion violation when the display
7874 string begins with a newline (egg.el). (Bug#11367)
7876 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
7878 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
7881 2012-05-01 Glenn Morris <rgm@gnu.org>
7883 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
7884 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
7885 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
7886 All were removed before 23.1.
7888 * dispnew.c: Remove HAVE_LIBNCURSES test;
7889 it is always true on relevant platforms.
7891 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
7892 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
7894 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
7896 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
7898 * .gdbinit (xpr): Remove checks for no longer existing misc types.
7899 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
7902 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
7904 Do not avoid creating empty evaporating overlays (Bug#9642).
7905 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
7906 That is, do not delete an evaporating overlay if it becomes
7907 empty after its bounds are adjusted to fit within its buffer.
7908 This fix caused other problems, and I'm reverting it until we get
7909 to the bottom of them.
7911 2012-04-27 Chong Yidong <cyd@gnu.org>
7913 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
7915 2012-04-27 Eli Zaretskii <eliz@gnu.org>
7917 * xdisp.c (pos_visible_p): If the window start position is beyond
7918 ZV, start the display from buffer beginning. Prevents assertion
7919 violation in init_iterator when the minibuffer window is scrolled
7922 * window.c (window_scroll_pixel_based): Likewise.
7924 2012-04-27 Chong Yidong <cyd@gnu.org>
7926 * keymap.c (where_is_internal): Doc fix (Bug#10872).
7928 2012-04-27 Glenn Morris <rgm@gnu.org>
7930 * fileio.c (Fcopy_file, Fset_file_selinux_context):
7931 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
7933 2012-04-27 Eli Zaretskii <eliz@gnu.org>
7935 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
7936 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
7938 2012-04-26 Eli Zaretskii <eliz@gnu.org>
7940 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
7941 display element, check also the underlying string or buffer
7942 character. (Bug#11341)
7944 * w32menu.c: Include w32heap.h.
7945 (add_menu_item): If the call to AppendMenuW (via
7946 unicode_append_menu) fails, disable Unicode menus only if we are
7947 running on Windows 9X/Me.
7949 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
7951 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
7952 (xgetint): Add missing shift for LSB tags.
7954 2012-04-24 Martin Rudalics <rudalics@gmx.at>
7956 * keyboard.c (read_char): Don't wipe echo area for select window
7957 events: These might get delayed via `mouse-autoselect-window'

7970 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
7972 Do not create empty overlays with the evaporate property (Bug#9642).
7973 * buffer.c (Fmove_overlay): Delete an evaporating overlay
7974 if it becomes empty after its bounds are adjusted to fit within
7975 its buffer. Without this fix, in a nonempty buffer (let ((o
7976 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
7977 yields an empty overlay that has the evaporate property, which is
7978 not supposed to happen.

8082 since the two debugging options are incompatible.
8083 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
8085 (mem_init, mem_insert, mem_insert_fixup):
8086 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

8095 * sysdep.c [__FreeBSD__]: Minor cleanups.
8096 (list_system_processes, system_process_attributes) [__FreeBSD__]:
8097 Use Emacs indenting style more consistently. Avoid some casts.
8098 Use 'double' consistently rather than mixing 'float' and 'double'.

8118 (print_object): Check for cycles even when print-circle is nil and
8119 print-gensym is t, but only check print_depth if print-circle is nil.
8121 2012-04-20 Chong Yidong <cyd@gnu.org>
8123 * process.c (wait_reading_process_output): If EIO occurs on a pty,
8124 set the status to "failed" and ensure that sentinel is run.

8179 New extern decls, to avoid calling undeclared functions.
8180 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
8181 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
8182 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
8183 (NEED_MEM_INSERT): New macro.
8184 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
8185 Remove one incorrect comment and fix another.

8199 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
8200 Remove decls. This fixes an "It stinks!".

8204 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
8206 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

8222 * s/netbsd.h, s/sol2-6.h:
8223 Remove definition of GC_MARK_STACK, since the default now works.
8224 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
8225 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
8226 no longer the default.
8227 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
8229 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

8252 2012-04-11 Daniel Colascione <dancol@dancol.org>
8254 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
8255 against is gone. It's better to use vfork now so that when Cygwin
8256 gains a new, working vfork, we use it automatically (bug#10398).
8258 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

8313 2012-04-09 Eli Zaretskii <eliz@gnu.org>
8315 * xdisp.c (set_cursor_from_row): If the display string appears in
8316 the buffer at position that is closer to point than the position
8317 after the display string, display the cursor on the first glyph of
8318 the display string. Fixes cursor display when a 'display' text
8319 property immediately follows invisible text. (Bug#11094)
8321 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
8323 composite.c: use 'double' consistently
8324 * composite.c (get_composition_id): Use 'double' consistently
8325 instead of converting 'float' to 'double' and vice versa; this is
8326 easier to understand and avoids a GCC warning.
8328 2012-04-09 Glenn Morris <rgm@gnu.org>
8330 * Makefile.in: Generate leim-list with bootstrap-emacs, in
8331 preparation for dumping it with emacs. (Bug#4789)

8375 [!WINDOWSNT]: New macros.
8376 (init_libxml2_functions, libxml2_loaded_p): New functions.
8377 (parse_region): Call fn_xmlCheckVersion instead of using the macro
8378 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
8379 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
8380 Calls xmlCleanupParser only if libxml2 was loaded (or statically
8382 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
8383 Call init_libxml2_functions before calling libxml2 functions.
8384 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
8386 * emacs.c: Don't include libxml/parser.h.
8387 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
8388 xmlCleanupParser directly.
8390 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
8392 2012-04-07 Eli Zaretskii <eliz@gnu.org>

8395 point, use it.vpos to compute how many lines to backtrack after
8396 move_it_to point. (Bug#11133)
8398 2012-04-06 Eli Zaretskii <eliz@gnu.org>
8400 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
8401 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
8402 about subtle differences between FETCH_CHAR* and STRING_CHAR*
8403 macros related to unification of CJK characters. For the details,
8404 see the discussion following the message here:
8405 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
8407 2012-04-04 Chong Yidong <cyd@gnu.org>
8409 * keyboard.c (Vdelayed_warnings_list): Doc fix.
8411 2012-04-01 Eli Zaretskii <eliz@gnu.org>
8413 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
8414 instead of alloca. (Bug#11138)
8416 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
8418 * w32menu.c (is_simple_dialog): Properly check lisp types.
8421 2012-03-31 Eli Zaretskii <eliz@gnu.org>
8423 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
8424 position we get to after a call to move_it_to fails the
8425 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
8426 only if we wind up in a string from display property. (Bug#11063)
8428 * window.c (Fdelete_other_windows_internal): Invalidate the row
8429 and column information about mouse highlight, so that redisplay
8430 restores it after reallocating the glyph matrices. (Bug#7464)
8432 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
8433 string comes from a `display' text property, use the buffer
8434 position of that property as if we actually saw that position in
8436 (move_it_by_lines): Remove the assertion that
8437 "it->current_x == 0 && it->hpos == 0" which can be legitimately
8438 violated when there's a before-string at the beginning of a line.
8441 2012-03-30 Eli Zaretskii <eliz@gnu.org>
8443 * xdisp.c (append_space_for_newline): If the default face was
8444 remapped, use the remapped face for the appended newline.
8445 (extend_face_to_end_of_line): Use the remapped default face for
8446 extending the face to the end of the line.
8447 (display_line): Call extend_face_to_end_of_line when the default
8448 face was remapped. (Bug#11068)
8450 2012-03-29 Eli Zaretskii <eliz@gnu.org>
8452 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
8454 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
8456 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
8458 2012-03-27 Glenn Morris <rgm@gnu.org>
8460 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
8463 2012-03-26 Kenichi Handa <handa@m17n.org>
8465 * dispextern.h (struct glyph): Fix previous change. Change the
8466 bit length of glyphless.ch to 25 (Bug#11082).
8468 2012-03-26 Chong Yidong <cyd@gnu.org>
8470 * keyboard.c (Vselection_inhibit_update_commands): New variable.
8471 (command_loop_1): Use it; inhibit selection update for
8472 handle-select-window too (Bug#8996).
8474 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
8476 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
8478 2012-03-25 Kenichi Handa <handa@m17n.org>
8480 * dispextern.h (struct glyph): Change the bit length of
8481 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
8483 2012-03-24 Eli Zaretskii <eliz@gnu.org>
8485 * s/ms-w32.h (tzname): Include time.h before redirecting to
8486 _tzname. Fixes the MSVC build. (Bug#9960)
8488 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
8490 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
8493 * xterm.c (XTread_socket): Only modify handling_signal if
8494 !SYNC_INPUT. (Bug#11080)
8496 2012-03-23 Eli Zaretskii <eliz@gnu.org>
8498 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
8499 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
8500 when fetching a multibyte character consumes more bytes than
8501 CHAR_BYTES returns, due to unification of CJK characters in
8502 string_char. (Bug#11073)
8504 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
8506 * process.c (wait_reading_process_output): Handle pty disconnect
8507 by refraining from sending oneself a SIGCHLD (bug#10933).
8509 2012-03-22 Chong Yidong <cyd@gnu.org>
8511 * dispextern.h (struct it): New member string_from_prefix_prop_p.
8513 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
8514 Mark string as coming from a prefix property.
8515 (handle_face_prop): Use default face for prefix strings (Bug#4281).
8516 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
8518 2012-03-21 Chong Yidong <cyd@gnu.org>
8520 * xfaces.c (Vface_remapping_alist): Doc fix.
8522 2012-03-20 Eli Zaretskii <eliz@gnu.org>
8524 * w32proc.c (Fw32_set_console_codepage)
8525 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
8528 2012-03-20 Chong Yidong <cyd@gnu.org>
8530 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
8531 to reflect default non-nil value of redisplay-dont-pause.
8533 2012-03-19 Kenichi Handa <handa@m17n.org>
8535 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
8536 it fit in a valid range (Bug#11003).
8538 2012-03-18 Eli Zaretskii <eliz@gnu.org>
8540 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
8541 that is not from display property, accept the row as a "cursor
8542 row" if one of the string's character has a non-nil `cursor'
8543 property. Fixes cursor positioning when there are newlines in
8544 overlay strings, e.g. in icomplete.el. (Bug#11035)
8546 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
8548 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
8550 2012-03-12 Chong Yidong <cyd@gnu.org>
8552 * eval.c (inhibit_lisp_code): Rename from
8553 inhibit_window_configuration_change_hook; move from window.c.
8555 * xfns.c (unwind_create_frame_1, Fx_create_frame):
8556 * window.c (run_window_configuration_change_hook)
8557 (syms_of_window): Callers changed.
8559 2012-03-11 Chong Yidong <cyd@gnu.org>
8561 * keymap.c (Fkey_description): Doc fix (Bug#9700).

8568 is visible (Bug#10955).
8570 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
8572 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
8574 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
8576 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
8577 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
8580 2012-03-03 Glenn Morris <rgm@gnu.org>
8582 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
8584 2012-03-02 Eli Zaretskii <eliz@gnu.org>
8586 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
8587 position past the first glyph_row that ends at ZV. (Bug#10902)
8588 (redisplay_window, next_element_from_string): Fix typos in
8590 (redisplay_window): Pass to move_it_vertically the margin in
8591 pixels, not in screen lines.
8593 2012-03-02 Glenn Morris <rgm@gnu.org>
8595 * buffer.c (buffer-list-update-hook): Doc fix.
8597 2012-02-29 Eli Zaretskii <eliz@gnu.org>
8599 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
8600 push_it before setting up the iterator for the first overlay
8601 string, even if we have an empty string loaded.
8602 (next_overlay_string): If there's an empty string on the iterator
8603 stack, pop the stack. (Bug#10903)
8605 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
8607 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
8608 Suggested by Stefan Monnier in
8609 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
8610 * alloc.c (widen_to_Lisp_Object): New static function.
8611 (mark_memory): Also mark Lisp_Objects by fetching pointer words
8612 and widening them to Lisp_Objects. This would work even if
8613 USE_LSB_TAG is defined and wide integers are used, which might
8614 happen in a future version of Emacs.
8616 2012-02-25 Chong Yidong <cyd@gnu.org>
8618 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
8621 * xselect.c (Fx_selection_exists_p): Doc fix.
8622 (x_clipboard_manager_save_all): Print an informative message
8623 before saving to clipboard manager.
8625 2012-02-24 Chong Yidong <cyd@gnu.org>
8627 * keyboard.c (process_special_events): Handle all X selection
8628 requests in kbd_buffer, not just the next one (Bug#8869).
8630 2012-02-23 Chong Yidong <cyd@gnu.org>
8632 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
8633 call when setting menu-bar-lines and tool-bar-lines parameters.
8634 (unwind_create_frame_1): New helper function.
8636 * window.c (inhibit_window_configuration_change_hook): New var.
8637 (run_window_configuration_change_hook): Obey it.
8638 (syms_of_window): Initialize it.
8640 2012-02-22 Chong Yidong <cyd@gnu.org>
8642 * xterm.c (x_draw_image_relief): Add missing type check for
8643 Vtool_bar_button_margin (Bug#10743).
8645 2012-02-21 Chong Yidong <cyd@gnu.org>
8647 * fileio.c (Vfile_name_handler_alist): Doc fix.
8649 * buffer.c (Fget_file_buffer): Protect against invalid file
8650 handler return value.
8652 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
8654 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
8655 when computing $valmask.
8657 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
8658 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
8659 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
8660 It's useless in that case, and it can cause problems on hosts
8661 that allocate halves of EMACS_INT values separately.
8662 Reported by Dan Horák. Diagnosed by Andreas Schwab in
8663 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
8664 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
8665 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
8666 it avoids undefined behavior on hosts where shifting right by more
8667 than the word width has undefined behavior.
8669 2012-02-19 Chong Yidong <cyd@gnu.org>
8671 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
8672 (Funhandled_file_name_directory, Ffile_name_as_directory)
8673 (Fdirectory_file_name, Fexpand_file_name)
8674 (Fsubstitute_in_file_name): Protect against invalid file handler
8675 return values (Bug#10845).
8677 2012-02-18 Eli Zaretskii <eliz@gnu.org>
8679 * .gdbinit (pitx): Fix incorrect references to fields of the
8682 2012-02-17 Chong Yidong <cyd@gnu.org>
8684 * syntax.c (Fscan_lists): Doc fix (Bug#10833).
8686 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>
8688 * image.c (MAX_IMAGE_SIZE): Increase from 6.0 to 10.0; see
8689 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
8691 2012-02-15 Chong Yidong <cyd@gnu.org>
8693 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
8694 marked as special. Also, starting docstrings with * is obsolete.
8696 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
8698 * gnutls.c (emacs_gnutls_write): Fix last change.
8700 2012-02-13 Lars Ingebrigtsen <larsi@gnus.org>
8702 * gnutls.c (emacs_gnutls_write): Set errno appropriately for
8705 2012-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
8707 * keymap.c (Fsingle_key_description): Handle char ranges.
8709 2012-02-12 Chong Yidong <cyd@gnu.org>
8711 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
8712 as that creates a dangerous corner case.
8714 * window.c (Fdelete_window_internal): Invalidate the mouse
8715 highlight (Bug#9904).
8717 2012-02-12 Glenn Morris <rgm@gnu.org>
8719 * xselect.c (Fx_own_selection_internal)
8720 (Fx_get_selection_internal, Fx_disown_selection_internal)
8721 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
8722 * nsselect.m (Fx_own_selection_internal)
8723 (Fx_disown_selection_internal, Fx_selection_exists_p)
8724 (Fx_selection_owner_p, Fx_get_selection_internal):
8725 Sync docs and argument specs with the xselect.c versions.
8727 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
8729 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
8731 2012-02-11 Eli Zaretskii <eliz@gnu.org>
8733 * w32select.c (Fx_selection_exists_p): Sync doc string and
8734 argument list with xselect.c. (Bug#10783)
8736 * w16select.c (Fx_selection_exists_p): Sync doc string and
8737 argument list with xselect.c. (Bug#10783)

8747 2012-02-07 Chong Yidong <cyd@gnu.org>
8749 * buffer.c (Fbuffer_local_variables)
8750 (buffer_lisp_local_variables): Handle unbound vars correctly;
8751 don't let Qunbound leak into Lisp.
8753 2012-02-07 Glenn Morris <rgm@gnu.org>
8755 * image.c (Fimagemagick_types): Doc fix.
8757 * image.c (imagemagick-render-type): Change it from a lisp object
8758 to an integer. Move the doc here from the lisp manual.

8761 2012-02-06 Chong Yidong <cyd@gnu.org>
8763 * doc.c (store_function_docstring): Avoid applying docstring of
8764 alias to base function (Bug#2603).
8766 2012-02-04 Andreas Schwab <schwab@linux-m68k.org>
8768 * .gdbinit (pp1, pv1): Remove redundant defines.
8771 2012-02-04 Chong Yidong <cyd@gnu.org>
8773 * nsterm.m: Declare a global (Bug#10694).
8775 2012-02-04 Eli Zaretskii <eliz@gnu.org>
8777 * w32.c (get_emacs_configuration_options):
8778 Include --enable-checking, if specified, in the return value.
8780 2012-02-04 Martin Rudalics <rudalics@gmx.at>
8782 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
8783 after rounding frame sizes. (Bug#9723)
8785 2012-02-04 Eli Zaretskii <eliz@gnu.org>
8787 * keyboard.c (adjust_point_for_property): Don't position point
8788 before BEGV. (Bug#10696)
8790 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
8792 Handle overflow when computing char display width (Bug#9496).
8793 * character.c (char_width): Return EMACS_INT, not int.
8794 (char_width, c_string_width): Check for overflow when
8795 computing the width; this is possible now that individual
8796 characters can have unbounded width. Problem introduced
8797 by merge from Emacs 23 on 2012-01-19.
8799 2012-02-02 Michael Albinus <michael.albinus@gmx.de>
8801 * dbusbind.c (Fdbus_register_method): Mention the return value

8814 2012-02-02 Kenichi Handa <handa@m17n.org>
8816 (x_produce_glyphs): Cancel previous change. If cmp->glyph_len is
8817 0, do not call append_composite_glyph.
8819 2012-02-02 Kenichi Handa <handa@m17n.org>
8821 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
8823 (x_produce_glyphs): If the component of a composition is a null
8824 string, set it->pixel_width to 1 to avoid zero-width glyph.
8826 2012-02-01 Eli Zaretskii <eliz@gnu.org>
8828 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
8829 first 2 arguments are identical. This makes inserting large
8830 output from a subprocess an order of magnitude faster on
8831 MS-Windows, where all sbrk'ed memory is always contiguous.
8833 2012-01-31 Glenn Morris <rgm@gnu.org>

8871 2012-01-21 Chong Yidong <cyd@gnu.org>
8873 * floatfns.c (Fcopysign): Make the second argument non-optional,
8874 since nil is not allowed anyway.
8876 2012-01-21 Andreas Schwab <schwab@linux-m68k.org>
8878 * process.c (read_process_output): Use p instead of XPROCESS (proc).
8879 (send_process): Likewise.

8885 Rewrite doc-strings.
8887 2012-01-19 Kenichi Handa <handa@m17n.org>
8889 * character.c (char_width): New function.
8890 (Fchar_width, c_string_width, lisp_string_width):
8891 Use char_width (Bug#9496).
8893 2012-01-16 Martin Rudalics <rudalics@gmx.at>
8895 * window.c (Vwindow_persistent_parameters): New variable.
8896 (Fset_window_configuration, save_window_save): Handle persistent
8899 2012-01-14 Eli Zaretskii <eliz@gnu.org>
8901 * w32fns.c (signal_user_input): Don't do a QUIT, to avoid
8902 thrashing the stack of the thread. (Bug#9087)

9446 Standardize on VIRT_ADDR_VARIES behavior (Bug#10042).
9447 Otherwise, valgrind does not work on some platforms.
9448 Problem reported by Andreas Schwab in
9449 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
9450 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
9451 is set, removing the need for VIRT_ADDRESS_VARIES.
9452 (PURE_P): Use a more-efficient implementation that needs just one
9453 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
9454 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
9455 to 4 (xorl, subq, cmpq, setbe).
9456 * alloc.c (pure): Always extern now, since that's the
9457 VIRT_ADDR_VARIES behavior.
9458 (PURE_POINTER_P): Use a single comparison, not two, for
9459 consistency with the new puresize.h.
9460 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
9461 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

9467 (erase_phys_cursor, update_window_cursor, show_mouse_face)
9468 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
9469 behave as if the cursor position were at the window margin.
9471 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
9472 and the cursor position is out of bounds, behave as if the cursor
9473 position were at the window margin. (Bug#10075)
9475 2011-11-18 Chong Yidong <cyd@gnu.org>
9477 * window.c (Fwindow_combination_limit): Make first argument

9498 * xdisp.c (row_hash): New function, body extracted from
9499 compute_line_metrics.
9500 (compute_line_metrics): Call row_hash, instead of computing the
9503 * dispnew.c (verify_row_hash): Call row_hash for computing the
9504 hash code of a row, instead of duplicating code from xdisp.c.
9506 * dispextern.h (row_hash): Add prototype.

9542 * image.c (imagemagick_load_image): Fix typo.
9544 2011-11-14 Eli Zaretskii <eliz@gnu.org>
9546 * xdisp.c (display_line): Move the call to
9547 highlight_trailing_whitespace before the call to
9548 compute_line_metrics, since the latter needs to see the final
9549 faces of all the glyphs to compute ROW's hash value.
9550 Fixes assertion violations in row_equal_p. (Bug#10035)
9552 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
9554 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,

9559 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
9560 with user-defined heap size. Bump the default size of the temacs
9561 heap to 27MB, to avoid memory warning when running temacs.
9562 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
9564 * dispnew.c (scrolling_window): Fix incorrect indices in accessing

9611 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
9613 Avoid some portability problems by eschewing 'extern inline' functions.
9614 The trivial performance wins aren't worth the portability hassles; see
9615 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
9617 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

9619 (window_box_right, window_box_right_offset): Undo previous change,
9620 by removing the "extern"s.
9621 * intervals.c (adjust_intervals_for_insertion)
9622 (adjust_intervals_for_deletion): Undo previous change,
9623 making these static again.
9624 (offset_intervals, temp_set_point_both, temp_set_point)
9625 (copy_intervals_to_string): No longer inline.
9626 * xdisp.c (window_text_bottom_y, window_box_width)

9692 (window_box_right, window_box_right_offset): Declare extern.
9693 Otherwise, these inline functions do not conform to C99 and
9694 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
9695 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
9696 * intervals.c (adjust_intervals_for_insertion)

9699 (static_offset_intervals): Remove.
9700 (offset_intervals): Rewrite using the old contents of
9701 static_offset_intervals. The old version didn't conform to C99
9702 because an extern inline function contained a reference to an
9703 identifier with static linkage.

9725 (Fwindow_vscroll): Doc fix.
9726 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
9727 argument, since it makes no sense to pass a live window and for

9756 (unwind_create_frame): New function (Bug#9943).
9757 (Fx_create_frame): Restructure code to be more similar to the one in
9758 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).
9759 Initialize image_cache_refcount if GLYPH_DEBUG (Bug#9943).
9760 Move terminal->reference_count++ just before making the frame official

9866 (get_current_wm_state): Return non-zero if not hidden,
9867 check for _NET_WM_STATE_HIDDEN (Bug#9893).
9868 (do_ewmh_fullscreen): Ignore return value from get_current_wm_state.
9869 (x_handle_net_wm_state): Return what get_current_wm_state returns.
9870 (x_term_init): Initialize dpyinfo->Xatom_net_wm_state_hidden.
9872 2011-10-29 Paul Eggert <eggert@cs.ucla.edu>
9874 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
9875 so that this new function doesn't get optimized away by a
9876 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
9878 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
9880 * frame.h (MOUSE_HL_INFO): Remove excess parens.
9882 2011-10-29 Eli Zaretskii <eliz@gnu.org>
9884 Fix the `xbytecode' command.
9885 * .gdbinit (xprintbytestr): New command.
9886 (xwhichsymbols): Rename from `which'; all callers changed.
9887 (xbytecode): Print the byte-code string as well.
9889 2011-10-29 Kim Storm <storm@cua.dk>
9891 * alloc.c (which_symbols): New function.
9893 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
9895 * minibuf.c (read_minibuf_noninteractive): Allow reading empty
9898 2011-10-29 Glenn Morris <rgm@gnu.org>
9900 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
9901 Not clear what it was for, and it causes various bugs. (Bug#9839)
9903 2011-10-28 Eli Zaretskii <eliz@gnu.org>
9905 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
9906 possible random value that matches one of those tested as
9907 condition to clear the mouse face.
9909 2011-10-28 Chong Yidong <cyd@gnu.org>
9911 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.
9913 2011-10-28 Dan Nicolaescu <dann@ics.uci.edu>
9915 * window.c (make_window): Initialize phys_cursor_on_p.
9917 2011-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
9919 * lisp.h (struct Lisp_Symbol): Update comments.
9921 2011-10-28 Juanma Barranquero <lekktu@gmail.com>
9923 * w32font.c (w32_load_unicows_or_gdi32): Add missing return.
9925 2011-10-28 Eli Zaretskii <eliz@gnu.org>
9927 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
9928 <oslsachem@gmail.com> for helping to debug this.
9930 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
9931 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
9932 (g_b_init_get_glyph_outline_w): New static variables.
9933 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
9934 (GetGlyphOutlineW_Proc): New typedefs.
9935 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
9936 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
9938 (w32font_open_internal, compute_metrics):
9939 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
9940 instead of calling the "wide" APIs directly.
9942 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
9944 * w32.h (syms_of_w32font): Add prototype.
9946 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
9948 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
9949 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
9950 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
9951 (Fmove_to_window_line): Doc fix.
9953 2011-10-27 Chong Yidong <cyd@gnu.org>
9955 * process.c (make_process): Set gnutls_state to NULL.
9957 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
9958 non-NULL, regardless of GNUTLS_INITSTAGE.
9959 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
9960 an error. Set process slots as soon as we allocate them.
9962 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
9964 2011-10-27 Chong Yidong <cyd@gnu.org>
9966 * gnutls.c (emacs_gnutls_deinit): New function.
9967 Deallocate credentials structures as well as calling gnutls_deinit.
9968 (Fgnutls_deinit, Fgnutls_boot): Use it.
9970 * process.c (make_process): Initialize GnuTLS credentials to NULL.
9971 (deactivate_process): Call emacs_gnutls_deinit.
9973 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
9975 * image.c (x_create_x_image_and_pixmap):
9976 * w32.c (sys_rename, w32_delayed_load):
9977 * w32font.c (fill_in_logfont):
9978 * w32reg.c (x_get_string_resource): Silence compiler warnings.
9980 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
9982 * w32fns.c (w32_default_color_map): New function,
9983 extracted from Fw32_default_color_map.
9984 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
9986 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
9988 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
9990 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
9992 * keyboard.c (test_undefined): New function (bug#9751).
9993 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
9995 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
9997 * sysdep.c (init_sys_modes): Fix the check for the controlling
9998 terminal (Bug#6649).
10000 2011-10-20 Eli Zaretskii <eliz@gnu.org>
10002 * dispextern.h (struct bidi_it): New member next_en_type.
10004 * bidi.c (bidi_line_init): Initialize the next_en_type member.
10005 (bidi_resolve_explicit_1): When next_en_pos is valid for the
10006 current character, check also for next_en_type being WEAK_EN.
10007 (bidi_resolve_weak): Don't enter the expensive loop if the current
10008 position is before next_en_pos. Record the bidi type of the first
10009 non-ET, non-BN character we find, in addition to its position.
10010 (bidi_level_of_next_char): Invalidate next_en_type when
10011 next_en_pos is over-stepped.
10013 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
10015 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
10016 * editfns.c: Rewrite current-time-zone so that it invokes
10017 the equivalent of (format-time-string "%Z") to get the time zone name.
10018 This fixes a bug when the time zone name contains characters that
10019 need converting from the system time locale to Emacs internal format.
10020 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
10021 that patch fixed format-time-string to do the conversion, but
10022 I forgot to fix current-time-zone.
10023 (format_time_string): New function, containing most of
10024 what Fformat_time_string used to contain.
10025 (Fformat_time_string): Rewrite in terms of format_time_string.
10026 This doesn't change this function's behavior.
10027 (current-time-zone): Rewrite to use format_time_string.
10028 This fixes the bug reported by Michael Schierl in
10029 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
10030 Jason Rumney's 2007-06-07 change worked around this bug, but
10032 * systime.h (tzname, timezone): Remove no-longer-used declarations.
10034 2011-10-19 Eli Zaretskii <eliz@gnu.org>
10036 * xdisp.c (start_display): If the character at POS is displayed
10037 via a display vector, reset IT->current.dpvec_index to zero.
10038 (try_window_reusing_current_matrix): If a line ends in a display
10039 vector or the next line starts in a display vector, continue
10040 redrawing the window even though the character position of
10041 start_row was reached.
10044 2011-10-18 Chong Yidong <cyd@gnu.org>
10046 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
10047 with nobreak-char-display too.
10049 2011-10-18 Eli Zaretskii <eliz@gnu.org>
10051 Fix part 3 of bug#9771.
10052 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
10053 (bidi_resolve_neutral): Don't enter the expensive loop looking for
10054 non-neutral characters if the current character is a paragraph
10055 separator (a.k.a. Newline). This avoids running the same
10056 expensive loop twice, once when we consume the preceding newline
10057 and the other time when the line actually needs to be displayed.
10058 Avoid the loop when we see neutrals on the base embedding level
10059 following a character whose directionality is the same as the
10060 paragraph's. This avoids running the expensive loop when a line
10061 ends in a long sequence of neutrals, like control characters.
10062 Add assertion against STRONG_AL type. Slightly rearrange code
10063 that determines the type of a neutral given the first non-neutral
10065 (bidi_level_of_next_char): Set next_en_pos to zero when
10066 invalidating its info.
10068 2011-10-17 Eli Zaretskii <eliz@gnu.org>
10070 * xdisp.c (push_display_prop): Determine whether to record string
10071 or buffer position by IT->string, not by IT->method. Allow
10072 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
10073 (move_it_vertically_backward): Don't look for character position
10074 immediately after the newline when in a continuation line.
10077 2011-10-15 Martin Rudalics <rudalics@gmx.at>
10079 * window.c (coordinates_in_window): Rewrite and delabelize
10080 vertical border check. (Bug#5357) (Bug#9618)
10082 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
10084 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
10085 errors in XSetWindowBorder (bug#9310).
10087 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
10089 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
10090 avoid crash when xmalloc overrun checking is enabled.
10092 2011-10-13 Eli Zaretskii <eliz@gnu.org>
10094 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
10095 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
10096 cursor motion with <left> and <right> arrow keys.
10098 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
10099 some callers set that themselves.
10101 2011-10-12 Eli Zaretskii <eliz@gnu.org>
10103 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
10104 display string and the previous row comes from the same string and
10105 is empty. (Bug#9739) (Bug#9738)
10107 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
10109 * doc.c (get_doc_string): Encode file name (bug#9735).
10111 2011-10-12 Eli Zaretskii <eliz@gnu.org>
10113 * bidi.c (bidi_level_of_next_char):
10114 * xdisp.c (get_visually_first_element): Remove old incorrect
10115 comments regarding the Unicode Line Separator character.
10117 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
10119 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
10121 * alloc.c (Fgc_status): Do not access beyond zombies array
10122 boundary if nzombies > MAX_ZOMBIES.
10123 * alloc.c (dump_zombies): Add missing format specifier.
10125 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
10127 * xdisp.c (set_cursor_from_row): Simplify conditionals,
10128 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
10130 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
10131 Some packages use them to denote characters with modifiers.
10133 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
10135 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
10136 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
10137 matching a pp-number. Rename parameter var to var1.
10139 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
10141 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
10143 2011-10-08 Glenn Morris <rgm@gnu.org>
10145 * callint.c (Fcall_interactively): Give a more explicit error for the
10146 'c' case with a non-character input. (Bug#8479)
10148 2011-10-08 Eli Zaretskii <eliz@gnu.org>
10150 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
10152 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
10153 lines that are hscrolled on the left.
10155 * dispnew.c (buffer_posn_from_coords): Account for a possible
10156 presence of header-line. (Bug#4426)
10158 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
10160 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
10161 Don't advertise functionality which we discourage or doesn't work.
10163 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
10165 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
10166 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
10167 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
10168 this makes Emacs dump core during garbage collection on rare
10169 occasions. sizeof is obviously inferior to offsetof here, so
10170 stick with offsetof.
10171 (GC_POINTER_ALIGNMENT): New macro.
10172 (mark_memory): Omit 3rd (offset) arg; caller changed.
10173 Don't assume EMACS_INT alignment is the same as pointer alignment.
10175 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
10177 * keyboard.c (read_key_sequence_remapped): New var.
10178 (read_key_sequence): Compute remapping in the right buffer.
10179 (command_loop_1): Use read_key_sequence's remapping directly.
10181 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
10183 * dired.c (file_name_completion): Don't expand file name.
10184 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
10185 before checking file name handler.
10187 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
10188 they've been requested explicitly (bug#9591).
10190 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
10192 * keymap.c (Fsingle_key_description): Use make_specified_string
10193 instead of build_string to build string from push_key_description.
10196 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
10198 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
10199 This fixes a Y2038 bug on 64-bit hosts.
10200 * buffer.c (reset_buffer):
10201 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
10202 (Fclear_buffer_auto_save_failure):
10203 Use 0, not -1, to represent an unset failure time, since time_t
10204 might not be signed.
10206 Remove dependency on glibc malloc internals.
10207 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
10208 Move back here from lisp.h, but with their new implementations.
10209 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
10210 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
10211 * charset.c (charset_table_init): New static var.
10212 (syms_of_charset): Use it instead of xmalloc. This removes a
10213 dependency on glibc malloc internals. See Eli Zaretskii's comment in
10214 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
10215 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
10216 Move back to alloc.c.
10217 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
10218 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
10220 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
10222 * nsterm.m (windowDidResize): Call x_set_window_size only when
10223 ns_in_resize is true. Otherwise set pixelwidth/height and
10224 call change_frame_size (Bug#9628).
10226 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
10228 Port --enable-checking=all to Fedora 14 x86-64.
10229 * charset.c (syms_of_charset): Also account for glibc malloc's
10230 internal overhead when calculating the initial malloc maximum.
10232 Port --enable-checking=all to Fedora 14 x86.
10233 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
10235 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
10236 (overrun_check_realloc, overrun_check_free):
10237 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
10238 That way, xmalloc returns a properly-aligned pointer even if
10239 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
10240 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
10241 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
10242 into account when calculating the initial malloc maximum.
10243 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
10244 Move here from alloc.c, so that charset.c can use it too.
10245 Properly align; the old code wasn't right for common 32-bit hosts
10246 when configured with --enable-checking=all.
10247 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
10248 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
10250 2011-09-29 Eli Zaretskii <eliz@gnu.org>
10252 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
10255 2011-09-28 Eli Zaretskii <eliz@gnu.org>
10257 * xdisp.c (compute_display_string_end): If there's no display
10258 string at CHARPOS, return -1.
10260 * bidi.c (bidi_fetch_char): When compute_display_string_end
10261 returns a negative value, treat the character as a normal
10262 character not covered by a display string. (Bug#9624)
10264 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
10266 * lread.c (Fread_from_string): Fix typo in docstring.
10268 2011-09-27 Eli Zaretskii <eliz@gnu.org>
10270 * xdisp.c (handle_invisible_prop): If invisible text ends on a
10271 newline, reseat the iterator instead of bidi-iterating there one
10272 character at a time. (Bug#9610)
10273 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
10274 TO_CHARPOS if the bidi iterator is at base embedding level.
10276 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
10278 * lread.c (readevalloop): Use correct code for NBSP.
10279 (read1): Likewise. (Bug#9608)
10281 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
10283 * dbusbind.c (Fdbus_register_signal): When service is not
10284 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
10286 2011-09-25 Glenn Morris <rgm@gnu.org>
10288 * buffer.c (truncate-lines): Doc fix.
10290 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
10292 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
10293 (Fset_window_next_buffers): Doc fix.
10295 2011-09-24 Glenn Morris <rgm@gnu.org>
10297 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
10299 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
10301 Fix minor problems found by static checking.
10302 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
10303 * indent.c (Fvertical_motion): Fix == vs = typo.
10305 2011-09-24 Eli Zaretskii <eliz@gnu.org>
10307 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
10308 Default value is now t. Doc fix.
10310 * indent.c (Fvertical_motion): Compute and apply the overshoot
10311 logic when moving up, not only when moving down. Fix the
10312 confusing name and values of the it_overshoot_expected variable;
10313 logic changes accordingly. (Bug#9254) (Bug#9549)
10315 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
10316 CHARPOS is covered by a display string which includes newlines.
10317 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
10318 is covered by a display string with embedded newlines.
10320 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
10322 * dbusbind.c (Fdbus_register_signal): Add match rule to
10323 Vdbus_registered_objects_table. (Bug#9581)
10324 (Fdbus_register_method, Vdbus_registered_objects_table):
10327 2011-09-24 Jim Meyering <meyering@redhat.com>
10329 do not ignore write error for any output size
10330 The previous change was incomplete.
10331 While it makes emacs --batch detect the vast majority of stdout
10332 write failures, errors were still ignored whenever the output size is
10333 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
10334 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
10335 && echo FAIL: ignored write error
10336 FAIL: ignored write error
10337 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
10338 && echo FAIL: ignored write error
10339 FAIL: ignored write error
10340 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
10342 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
10344 * emacs.c (Fkill_emacs): In noninteractive mode exit
10345 non-successfully if a write error occurred on stdout. (Bug#9574)
10347 2011-09-21 Eli Zaretskii <eliz@gnu.org>
10349 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
10352 * dispextern.h (struct it): Update the comment documenting what
10355 2011-09-20 Eli Zaretskii <eliz@gnu.org>
10357 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
10358 a display string, extend search for cursor position to end of row.
10359 (find_row_edges): If the row ends in a newline from a display
10360 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
10361 Handle the case of a display string with multiple newlines.
10362 (Fcurrent_bidi_paragraph_direction): Fix search for previous
10363 non-empty line. Fixes confusing cursor motion with arrow keys at
10364 the beginning of a line that starts with whitespace.
10366 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
10368 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
10371 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
10373 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
10374 boolean (Bug#9154).
10376 2011-09-18 Eli Zaretskii <eliz@gnu.org>
10378 * xdisp.c (display_line): Record maximum and minimum buffer
10379 positions even if no glyphs were produced (e.g., by a zero-width
10380 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
10381 buffer positions that will be removed from the glyph row because
10383 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
10384 column is beyond frame width: don't subtract 1 "pixel" when
10385 computing width of the stretch.
10386 (reseat_at_next_visible_line_start): Undo the change made on
10387 2011-09-17 that saved paragraph information and restored it after
10388 the call to `reseat'. (Bug#9545)
10390 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
10392 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
10393 and turn window cursor on if cleared (Bug#9415).
10395 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
10397 * search.c (boyer_moore): Take unibyte characters from pattern
10398 literally. (Bug#9458)
10400 2011-09-18 Eli Zaretskii <eliz@gnu.org>
10402 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
10404 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
10406 Fix minor problem found by static checking.
10407 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
10408 initialized, to pacify gcc -Wuninitialized.
10410 * fileio.c: Report proper errno when syscall falls.
10411 (Finsert_file_contents): Save and restore errno,
10412 so that report_file_error outputs the correct diagnostic.
10413 (Fwrite_region) [CLASH_DETECTION]: Likewise.
10415 2011-09-18 Eli Zaretskii <eliz@gnu.org>
10417 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
10419 2011-09-17 Eli Zaretskii <eliz@gnu.org>
10421 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
10422 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
10424 2011-09-17 Eli Zaretskii <eliz@gnu.org>
10426 * xdisp.c (reseat_at_next_visible_line_start): Keep information
10427 about the current paragraph and restore it after the call to reseat.
10429 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
10430 (bidi_find_paragraph_start): Search back for paragraph beginning
10431 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
10432 (bidi_move_to_visually_next): Only trigger paragraph-related
10433 computations when the last character is a newline or at EOB, not
10434 just any NEUTRAL_B. (Bug#9470)
10436 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
10437 truncated lines if point is covered by a display string. (Bug#9524)
10439 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
10441 * xselect.c: Relax test for outgoing X longs (Bug#9498).
10442 (cons_to_x_long): New function.
10443 (lisp_data_to_selection_data): Use it. Correct the test for
10444 short-versus-long data; it was negated. Break out of vector
10445 loop, for efficiency, when a long datum is discovered.
10447 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
10449 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
10451 2011-09-16 Eli Zaretskii <eliz@gnu.org>
10453 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
10454 GCC PR/17406) by declaring this function with external scope.
10456 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
10458 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
10459 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
10461 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
10463 * editfns.c (Fformat): Correctly handle text properties on "%%".

10471 * xdisp.c (get_next_display_element)
10472 (fill_composite_glyph_string): Add comments about special meaning
10473 of TAB characters in a composition.
10475 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
10477 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
10478 This occurs when processing a multibyte format.
10479 Problem reported by Wolfgang Jenker.
10481 2011-09-15 Johan Bockgård <bojohan@gnu.org>
10483 * xdisp.c (try_cursor_movement): Only check for exact match if
10484 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
10486 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
10488 Remove unused external symbols.
10489 * dispextern.h (calc_pixel_width_or_height): Remove decl.
10490 * xdisp.c (calc_pixel_width_or_height): Now static.
10491 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
10492 * indent.c (check_display_width):
10493 * w32term.c: Fix comment to match code.
10494 * xterm.c, xterm.h (x_catching_errors): Remove.
10496 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
10498 * xselect.c: Use signed conversions more consistently (Bug#9498).
10499 (selection_data_to_lisp_data): Assume incoming selection data are
10500 signed integers, not unsigned. This is to be consistent with
10501 outgoing selection data, which was modified to use signed integers
10502 in as part of the fix to Bug#9196 in response to Jan D.'s comment
10503 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
10504 expects long, not unsigned long.
10506 2011-09-14 Eli Zaretskii <eliz@gnu.org>
10508 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
10509 computation of loop end. Reported by Johan Bockgård
10512 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
10514 * frame.c (Fother_visible_frames_p): Function deleted.
10516 2011-09-12 Eli Zaretskii <eliz@gnu.org>
10518 * indent.c (compute_motion): Process display vector front to back
10519 rather than the other way around. (Bug#2496)
10521 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
10523 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
10525 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
10527 * minibuf.c (Fread_from_minibuffer): Doc fix.
10529 2011-09-11 Eli Zaretskii <eliz@gnu.org>
10531 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
10532 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
10534 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
10536 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
10537 value for non-existent files.
10539 2011-09-11 Eli Zaretskii <eliz@gnu.org>
10541 * fileio.c (Finsert_file_contents): If the file cannot be opened,
10542 set its "size" to -1. This will set the modtime_size field of
10543 the corresponding buffer to -1, which is what
10544 verify-visited-file-modtime expects for files that do not exist.
10547 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
10549 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
10551 * lisp.h: ... from here. push_key_description is no longer
10552 defined in keyboard.c, so its declaration should not be in
10553 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
10554 logically belongs with push_key_description.
10556 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
10558 * buffer.h: Include <sys/types.h> instead of <time.h>.
10559 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
10560 Problem reported by Herbert J. Skuhra.
10562 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
10564 * xml.c (parse_region): Make the parsing work for
10565 non-comment-starting XML files again (bug#9144).
10567 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
10569 * image.c (gif_load): Fix calculation of bottom and right corner.
10572 2011-09-10 Eli Zaretskii <eliz@gnu.org>
10574 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
10575 redisplay in small windows.
10577 2011-09-09 Eli Zaretskii <eliz@gnu.org>
10579 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
10581 2011-09-08 Martin Rudalics <rudalics@gmx.at>
10583 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
10584 Operate on live windows only.
10586 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
10588 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
10590 2011-09-07 Eli Zaretskii <eliz@gnu.org>
10592 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
10593 only under bidi iteration.
10595 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
10597 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
10599 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
10601 isnan: Fix porting problem to Solaris 10 with bundled gcc.
10602 Without this fix, the command to link temacs failed due to an
10603 undefined symbol __builtin_isnan. This is because
10604 /usr/include/iso/math_c99.h #defines isnan(x) to
10605 __builtin_isnan(x), but the bundled gcc, which identifies itself
10606 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
10608 * floatfns.c (isnan): #undef, and then #define to a clone of
10610 (Fisnan): Always define, since it's always available now.
10611 (syms_of_floatfns): Always define isnan at the Lisp level.
10613 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
10615 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
10617 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
10619 * fileio.c: Fix bugs with large file offsets (Bug#9428).
10620 The previous code assumed that file offsets (off_t values) fit in
10621 EMACS_INT variables, which is not true on typical 32-bit hosts.
10622 The code messed up by falsely reporting buffer overflow in cases
10623 such as (insert-file-contents "big" nil 1 2) into an empty buffer
10624 when "big" contains more than 2**29 bytes, even though this
10625 inserts just one byte and does not overflow the buffer.
10626 (Finsert_file_contents): Store file offsets as off_t
10627 values, not as EMACS_INT values. Check for overflow when
10628 converting between EMACS_INT and off_t. When checking for
10629 buffer overflow or for overlap, take the offsets into account.
10630 Don't use EMACS_INT for small values where int suffices.
10631 When checking for overlap, fix a typo: ZV was used where
10632 ZV_BYTE was intended.
10633 (Fwrite_region): Don't assume off_t fits into 'long'.
10634 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
10636 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
10638 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
10640 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
10642 sprintf-related integer and memory overflow issues (Bug#9412).
10644 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
10645 (esprintf, exprintf, evxprintf): New functions.
10646 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
10647 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
10648 (modify_event_symbol): Do not assume that the length of
10649 name_alist_or_stem is safe to alloca and fits in int.
10650 (Fexecute_extended_command): Likewise for function name and binding.
10651 (Frecursion_depth): Wrap around reliably on integer overflow.
10652 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
10653 since some callers pass EMACS_INT values.
10654 (Fsingle_key_description): Don't crash if symbol name contains more
10655 than MAX_ALLOCA bytes.
10656 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
10657 (get_minibuffer): Arg is now EMACS_INT, not int.
10658 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
10659 (esprintf, exprintf, evxprintf): New decls.
10660 * window.h (command_loop_level, minibuf_level): Reflect API changes.
10662 * dbusbind.c (signature_cat): New function.
10663 (xd_signature, Fdbus_register_signal):
10664 Do not overrun buffer; instead, report string overflow.
10666 * dispnew.c (add_window_display_history): Don't overrun buffer.
10667 Truncate instead; this is OK since it's just a log.
10669 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
10670 even if the time zone offset is outlandishly large.
10671 Don't mishandle offset == INT_MIN.
10673 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
10674 when creating daemon; the previous buffer-overflow check was incorrect.
10676 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
10677 which has the guts of the old verror function.
10679 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
10680 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
10682 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
10683 (font_unparse_xlfd): Don't blindly alloca long strings.
10684 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
10685 fits in int, when using sprintf. Use single snprintf to count
10686 length of string rather than counting it via multiple sprintfs;
10687 that's simpler and more reliable.
10688 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
10689 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
10690 sprintf, in case result does not fit in int.
10692 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
10693 (fontset_from_font): Print it.
10695 * frame.c (tty_frame_count): Now printmax_t, not int.
10696 (make_terminal_frame, set_term_frame_name): Print it.
10697 (x_report_frame_params): In X, window IDs are unsigned long,
10698 not signed long, so print them as unsigned.
10699 (validate_x_resource_name): Check for implausibly long names,
10700 and don't assume name length fits in 'int'.
10701 (x_get_resource_string): Don't blindly alloca invocation name;
10702 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
10705 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
10706 (xg_check_special_colors, xg_set_geometry):
10707 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
10709 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
10710 Use esprintf, not sprintf, in case result does not fit in int.
10712 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
10713 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
10714 it as a large positive number.
10715 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
10716 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
10718 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
10719 in case result does not fit in int.
10721 * print.c (float_to_string): Detect width overflow more reliably.
10722 (print_object): Make sprintf buffer a bit bigger, to avoid potential
10723 buffer overrun. Don't assume list length fits in 'int'. Treat
10724 print length of 0 as 0, not as infinity; to be consistent with other
10725 uses of print length in this function. Don't overflow print length
10726 index. Don't assume hash table size fits in 'long', or that
10727 vectorlike size fits in 'unsigned long'.
10729 * process.c (make_process): Use printmax_t, not int, to format
10730 process-name gensyms.
10732 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
10734 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
10735 to avoid potential buffer overrun.
10737 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
10738 if X resource line is longer than 512 bytes.
10740 * xfns.c (x_window): Make sprintf buffer a bit bigger
10741 to avoid potential buffer overrun.
10743 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
10745 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
10747 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
10749 Integer overflow fixes for scrolling, etc.
10750 Without these, Emacs silently mishandles large integers sometimes.
10751 For example, "C-u 4294967297 M-x recenter" was treated as if
10752 it were "C-u 1 M-x recenter" on a typical 64-bit host.
10754 * xdisp.c (try_window_id): Check Emacs fixnum range before
10755 converting to 'int'.
10757 * window.c (window_scroll_line_based, Frecenter):
10758 Check that an Emacs fixnum is in range before assigning it to 'int'.
10759 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
10760 values converted from Emacs fixnums.
10761 (Frecenter): Don't wrap around a line count if it is out of 'int'
10762 range; instead, treat it as an extreme value.
10763 (Fset_window_configuration, compare_window_configurations):
10764 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
10766 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
10767 that can exceed INT_MAX. Check that EMACS_INT value is in range
10768 before assigning it to the (possibly-narrower) index.
10769 (match_limit): Don't assume that a fixnum can fit in 'int'.
10771 * print.c (print_object): Use ptrdiff_t, not int, for index that can
10774 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
10775 (Fvertical_motion): Don't wrap around LINES values that don't fit
10776 in 'int'. Instead, treat them as extreme values. This is good
10777 enough for windows, which can't have more than INT_MAX lines anyway.
10779 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
10781 * Require libxml/parser.h to avoid compilation warning.
10783 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
10785 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
10786 since this reportedly can destroy thread storage.
10788 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
10790 * syntax.c (find_defun_start): Update all cache variables if
10791 exiting early (Bug#9401).
10793 2011-08-30 Eli Zaretskii <eliz@gnu.org>
10795 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
10797 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
10798 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
10799 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
10801 * term.c (tty_append_glyph): New function.
10802 (produce_stretch_glyph): Static function and its prototype deleted.
10804 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
10807 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
10809 * image.c (parse_image_spec): Check for nonnegative, not for positive,
10810 when checking :margin (Bug#9390).
10811 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
10812 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
10813 so that the name doesn't mislead. All uses changed.
10815 2011-08-28 Johan Bockgård <bojohan@gnu.org>
10817 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after

10822 * xdisp.c (move_it_to): Don't bail out early when reaching
10823 position beyond to_charpos, if we are scanning backwards.
10824 (move_it_vertically_backward): When DY == 0, make sure we get to
10825 the first character in the line after the newline.
10827 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
10829 * ccl.c: Improve and simplify overflow checking (Bug#9196).
10830 (ccl_driver): Do not generate an out-of-range pointer.
10831 (Fccl_execute_on_string): Remove unnecessary check for
10832 integer overflow, noted by Stefan Monnier in
10833 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
10834 Remove a FIXME that didn't need fixing.
10835 Simplify the newly-introduced buffer reallocation code.
10837 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
10839 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
10841 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
10843 Integer and memory overflow issues (Bug#9196).
10845 * doc.c (get_doc_string): Rework so that
10846 get_doc_string_buffer_size is the actual buffer size, rather than
10847 being 1 less than the actual buffer size; this makes xpalloc more
10850 * image.c (x_allocate_bitmap_record, cache_image):
10851 * xselect.c (Fx_register_dnd_atom):
10852 Simplify previous changes by using xpalloc.
10854 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
10855 since either will do and ptrdiff_t is convenient with xpalloc.
10857 * charset.c (charset_table_size)
10858 (struct charset_sort_data.priority): Now ptrdiff_t.
10859 (charset_compare): Don't overflow if priorities differ greatly.
10860 (Fsort_charsets): Don't assume list length fits in int.
10861 Check for size-calculation overflow when allocating sort data.
10862 (syms_of_charset): Allocate an initial charset table that is
10863 just under 64 KiB, to avoid problems with glibc malloc and mmap.
10865 * cmds.c (internal_self_insert): Check for size-calculation overflow.
10867 * composite.h (struct composition.glyph_len): Now int, not unsigned.
10868 The actual value is always <= INT_MAX, and leaving it unsigned made
10869 overflow checking harder.
10871 * dispextern.h (struct glyph_matrix.rows_allocated)
10872 (struct face_cache.size): Now ptrdiff_t, for convenience in use
10873 with xpalloc. The values are still always <= INT_MAX.
10875 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
10877 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
10878 (SAFE_NALLOCA): New macro.
10880 * region-cache.c (struct boundary.pos, find_cache_boundary)
10881 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
10882 (set_cache_region, invalidate_region_cache)
10883 (revalidate_region_cache, know_region_cache, region_cache_forward)
10884 (region_cache_backward, pp_cache):
10885 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
10886 so that ptrdiff_t * can be passed to xpalloc.
10887 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
10888 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
10889 (pp_cache): Don't assume cache_len fits in int.
10890 * region-cache.h: Adjust extern decls to match.
10892 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
10893 EMACS_INT, since either will do, for xpalloc.
10895 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
10896 (xnmalloc, xnrealloc, xpalloc): New functions.
10898 * bidi.c (bidi_shelve_header_size): New constant.
10899 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
10900 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
10902 * bidi.c (bidi_cache_shrink):
10903 * buffer.c (overlays_at, overlays_in, record_overlay_string)
10905 Don't update size of array until after memory allocation succeeds,
10906 because xmalloc/xrealloc may not return.
10907 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
10908 now that we have proper integer overflow checking.
10909 (record_overlay_string, overlay_strings): Catch overflows when
10910 calculating size of overlay_str_buf.
10912 * callproc.c (Fcall_process): Check for size overflow when
10913 calculating size of args2.
10914 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
10915 Normally we prefer signed values, but sticking with ptrdiff_t would
10916 require adding more-complicated checks.
10918 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
10919 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
10920 Redo buffer-overflow calculations to avoid integer overflow.
10921 Add a FIXME comment where memory seems to be over-allocated.
10923 * character.c (Fstring): Check for size-calculation overflow.
10925 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
10926 unnecessary integer overflow. Check for size overflow.
10927 (encode_coding_object): Don't update size until xmalloc succeeds.
10929 * composite.c (get_composition_id): Check for overflow in glyph
10930 length calculations.
10932 Integer and memory overflow fixes for display code.
10933 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
10934 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
10935 (scrolling_window): Check for overflow in size calculations.

10947 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
10948 (get_doc_string): Check for size calculation overflow.
10949 Don't update size until allocation succeeds.
10950 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
10951 EMACS_INT, where ptrdiff_t will do.
10952 (Fsubstitute_command_keys): Check for string overflow.
10954 * editfns.c (set_time_zone_rule): Don't assume environment length
10956 (message_length): Now ptrdiff_t, not int.
10957 (Fmessage_box): Don't update size until allocation succeeds.
10958 Don't assume message length fits in int.
10959 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
10961 * emacs.c (main): Do not reallocate argv, since there is a null at
10962 the end that can be overwritten, and this way there's no need to
10963 worry about size-calculation overflow.
10964 (sort_args): Check for size-calculation overflow.
10966 * eval.c (init_eval_once, grow_specpdl): Don't update size until
10968 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
10970 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
10971 (x_set_scroll_bar_width, x_figure_window_size):
10972 Check for integer overflow.
10973 (x_set_alpha): Do not assume XINT fits in int.
10975 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
10976 This is for the members text_lines, text_cols, total_lines, total_cols,
10977 where the system imposes an 'int' limit.
10979 * fringe.c (Fdefine_fringe_bitmap):
10980 Don't update size until alloc works.
10982 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
10983 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
10985 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
10986 Check for size-calculation overflow.
10987 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
10988 do, as we prefer signed integers.
10989 (id_to_widget.max_size, id_to_widget.used)
10990 (xg_store_widget_in_map, xg_remove_widget_from_map)
10991 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
10992 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
10993 Use and return ptrdiff_t, not int.
10994 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
10995 * gtkutil.h: Change prototypes to match the above.
10997 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
10998 are duplicate now that they've been promoted to lisp.h.
10999 (x_allocate_bitmap_record, x_alloc_image_color)
11000 (make_image_cache, cache_image, xpm_load):
11001 Don't update size until alloc is done.

11012 Use ptrdiff_t, not int, to count maps.
11013 (read_char_minibuf_menu_prompt): Check for overflow in size
11014 calculations. Don't update size until allocation succeeds.
11015 Redo calculations to avoid overflow.
11016 * keyboard.h: Change prototypes to match the above.
11018 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,

11044 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
11045 for command line length. Do not attempt to address one before the
11046 beginning of an array, as that's not portable.
11048 * term.c (max_frame_lines): Remove; unused.
11049 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
11051 (encode_terminal_code, calculate_costs): Check for size

11058 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
11059 subtracting pointers.

11081 (Fx_change_window_property): Use ptrdiff_t, not int, to count
11082 sizes, since they can exceed INT_MAX in size. Check for size

11086 (xg_select): Check for size calculation overflow.
11087 Don't update size until alloc done.
11089 * xrdb.c (get_environ_db): Don't assume path length fits in int,
11090 as sprintf is limited to int lengths.
11092 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
11093 (X_LONG_MIN): New macros.
11094 Use them to make the following changes clearer.
11095 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
11096 This change doesn't affect the value now, but it may help remind
11097 future maintainers not to raise the value too much later.
11098 (SELECTION_QUANTUM): Remove, replacing with ...
11099 (selection_quantum): ... new function, which avoids overflow.
11101 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
11102 assumption that selection length fits in 'int'.

11115 (lisp_data_to_selection_data, x_property_data_to_lisp):

11119 Don't store size until memory allocation succeeds.
11120 (x_get_window_property): Plug memory leak on memory exhaustion.
11121 Don't double-block input; malloc is safe here. Don't assume 2**34
11122 - 4 fits in unsigned long. Add an xassert to check
11123 XGetWindowProperty overflow. Be more careful about overflow
11124 calculations, and distinguish size from memory overflow better.
11125 (receive_incremental_selection): When tracing, don't assume
11126 unsigned int is less than INT_MAX.
11127 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
11128 harmful) conversions of unsigned short to int.
11129 (lisp_data_to_selection_data): Don't assume that integers
11130 in the range -65535 through -1 fit in an X unsigned short.
11131 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
11132 result parameters unless successful. Rely on cons_to_unsigned
11133 to report problems with elements; the old code wasn't right anyway.
11134 (x_check_property_data): Check for int overflow; we cannot use
11135 a wider type due to X limits.
11136 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

11168 * lisp.h (hash_lookup, hash_put):
11169 * minibuf.c (Ftest_completion):
11170 Use ptrdiff_t for hash table indexes, not int (which is too
11171 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
11172 32-bit --with-wide-int hosts).
11174 * charset.c (Fdefine_charset_internal): Check for integer overflow.
11175 Add a FIXME comment about memory leaks.
11176 (syms_of_charset): Don't assume xmalloc returns.
11178 Don't assume that stated character widths fit in int.

11180 * character.h (CHAR_WIDTH):
11181 * indent.c (MULTIBYTE_BYTES_WIDTH):
11182 Use sanitize_char_width to avoid undefined and/or bad behavior
11183 with outlandish widths.
11184 * character.h (sanitize_tab_width): Rename from sanitize_width,
11185 now that we have two such functions. All uses changed.
11186 (sanitize_char_width): New inline function.
11188 Don't assume that tab-width fits in int.

11206 exceed limits imposed by XClientMessageEvent, as well as the usual
11207 ptrdiff_t and size_t limits.
11209 * keyboard.c: Overflow, signedness and related fixes.
11210 (make_lispy_movement): Use same integer type in forward decl
11211 that is used in the definition.
11212 (read_key_sequence, keyremap_step):
11213 Change bufsize argument back to int, undoing my 2011-03-30 change.
11214 We prefer signed types, and int is wide enough here.
11215 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
11216 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
11217 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
11218 length, not size_t. Use ptrdiff_t for index, not int.
11219 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
11220 possibility of integer overflow.
11222 Overflow, signedness and related fixes for images.
11224 * dispextern.h (struct it.stack[0].u.image.image_id)
11225 (struct_it.image_id, struct image.id, struct image_cache.size)
11226 (struct image_cache.used, struct image_cache.ref_count):
11227 * gtkutil.c (update_frame_tool_bar):

11232 * xdisp.c (calc_pixel_width_or_height):
11233 * xfns.c (image_cache_refcount):
11234 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
11235 on typical 64-bit hosts.
11237 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
11238 (x_bitmap_pixmap, x_create_x_image_and_pixmap):

11243 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
11244 (lookup_image): Remove unnecessary tests.
11245 (xbm_image_p): Locals are now of int, not EMACS_INT,
11246 since parse_image_check makes sure they fit into int.
11247 (png_load, gif_load, svg_load_image):
11248 Prefer int to unsigned where either will do.
11249 (tiff_handler): New function, combining the cores of the
11250 old tiff_error_handler and tiff_warning_handler.
11251 This function is rewritten to use vsnprintf and thereby avoid
11252 stack buffer overflows. It uses only the features of vsnprintf
11253 that are common to both POSIX and native Microsoft.
11254 (tiff_error_handler, tiff_warning_handler): Use it.
11255 (tiff_load, gif_load, imagemagick_load_image):
11256 Don't assume :index value fits in 'int'.
11257 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
11258 (imagemagick_load_image): Check that crop parameters fit into
11259 the integer types that MagickCropImage accepts. Don't assume
11260 Vimagemagick_render_type has a nonnegative value. Don't assume
11261 size_t fits in 'long'.
11262 (gs_load): Use printmax_t to print the widest integers possible.
11263 Check for integer overflow when computing image height and width.
11265 2011-08-26 Eli Zaretskii <eliz@gnu.org>
11267 * xdisp.c (redisplay_window): Don't force window start if point

11275 handle_single_display_spec, not just 1 or zero.
11276 (handle_single_display_spec): If the display spec is of the form
11277 `(space ...)', and specifies display in the text area, return 2
11279 (try_cursor_movement): Check for the need to scroll more
11280 accurately, and prefer exact match for point under bidi.
11281 Don't advance `row' beyond the last row of the window.
11283 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
11284 into disp_prop; all users changed.
11286 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
11287 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
11288 for the text covered by the display property.

11298 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
11299 buffers, return left-to-right.
11300 (set_cursor_from_row): Consider candidate row a win if its glyph
11301 represents a newline and point is on that newline. Fixes cursor
11302 positioning on the newline at EOL of R2L text within L2R
11303 paragraph, and vice versa.
11304 (try_cursor_movement): Check continued rows, in addition to
11305 continuation rows. Fixes unwarranted scroll when point enters a
11306 continued line of R2L text within an L2R paragraph, or vice versa.
11307 (cursor_row_p): Consider the case of point being equal to
11308 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
11309 from the end of a short line to the beginning of a continued line
11310 of R2L text within L2R paragraph.
11311 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
11312 composed characters.
11314 * bidi.c (bidi_check_type): Use xassert.

11325 * nsfont.m (ns_otf_to_script): Fix typo.
11327 2011-08-22 Kenichi Handa <handa@m17n.org>
11329 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
11330 extra slot even if the purpose is char-code-property-table.
11332 2011-08-23 Eli Zaretskii <eliz@gnu.org>
11334 * xdisp.c (redisplay_window): When computing centering_position,
11335 account for the height of the header line. (Bug#8874)
11337 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
11338 instead of CHAR_TO_BYTE. Fixes a crash when a completion
11339 candidate is selected by the mouse, and that candidate has a
11340 composed character under the mouse.
11342 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
11343 coordinates reported by pos-visible-in-window-p for a composed
11344 character in column zero.
11346 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
11348 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
11350 2011-08-22 Eli Zaretskii <eliz@gnu.org>
11352 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
11353 consider it a hit if to_charpos is anywhere in the range of the
11354 composed buffer positions.
11356 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
11358 * image.c (gif_load): Don't assume that each subimage has the same
11359 dimensions as the base image. Handle disposal method that is
11360 "undefined" by the gif spec (Bug#9335).
11362 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
11364 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).
11365 (Fcondition_case): Document `debug' symbol in error handler.
11367 2011-08-19 Eli Zaretskii <eliz@gnu.org>
11369 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
11370 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
11371 from an Org mode buffer to a Speedbar frame.
11373 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
11374 a composition, take its buffer position from IT->cmp_it.charpos.
11375 Fixes cursor positioning at the beginning of a line that begins
11376 with a composed character.
11378 2011-08-18 Eli Zaretskii <eliz@gnu.org>
11380 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
11381 character bidirectional type, use STRONG_L instead. Fixes crashes
11382 in a buffer produced by `describe-categories'.
11384 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
11385 members before the level stack, so they would be saved and
11386 restored when copying iterator state. Fixes incorrect reordering
11387 around TABs covered by display properties.
11389 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
11391 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

11461 * xdisp.c (move_it_in_display_line_to): Don't invoke
11462 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
11463 ppos_it. Fixes vertical cursor motion when line beginning is
11464 covered by an image. (Bug#9296)
11466 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
11468 * nsterm.h (ns_run_ascript): Declare.

11472 (ns_run_ascript): New function.
11473 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
11474 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
11475 the event loop. Get status from as_status (Bug#7276).
11477 * nsterm.m (sendEvent): If event is NSApplicationDefined and
11478 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
11479 the event loop (Bug#7276).
11481 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>

11505 (Fnetwork_interface_list): Allocate in increments of bytes instead
11506 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
11507 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
11509 (struct ifflag_def): notrailers is smart on OSX.
11510 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
11511 Get hardware address with getifaddrs if available.
11513 2011-08-12 Eli Zaretskii <eliz@gnu.org>

11519 Set IT->current to match the bidi iterator unconditionally.
11520 (push_display_prop): Allow GET_FROM_STRING as IT->method on
11521 entry. Force push_it to save on the stack the current
11522 buffer/string position, to be restored by pop_it. Fix flags in
11523 the iterator structure wrt the object coming from a display
11524 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
11525 properties. (Bug#9284)
11527 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
11529 * fontset.c (fontset_get_font_group): Add proper type checks.

11557 restore_point_unwind (Bug#5984).
11559 2011-08-07 Juri Linkov <juri@jurta.org>
11561 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'

11568 longlines-mode. (Bug#9254)
11569 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
11570 word-wrap under bidirectional display. (Bug#9224)
11572 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
11573 is non-zero, even if the data buffer is NULL. Fixes a crash in
11574 vertical-motion with longlines-mode. (Bug#9254)
11576 2011-08-05 Eli Zaretskii <eliz@gnu.org>
11578 * bidi.c <bidi_cache_total_alloc>: Now static.

11584 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
11585 amount allocated this far in `bidi_cache_total_alloc'.
11586 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
11587 non-zero, only free the data buffer without restoring the cache
11588 contents. All callers changed.
11590 * dispextern.h (bidi_unshelve_cache): Update prototype.
11592 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)

11675 BIDI_IT_PREV, and store into it the state of the bidi iterator had
11677 (reseat_at_next_visible_line_start): Use the bidi iterator state
11678 returned by forward_to_next_line_start to restore the state of
11679 it->bidi_it after backing up to previous newline. (Bug#9212)
11681 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
11683 * regex.c (re_comp): Protoize.
11684 (re_exec): Fix return type.
11685 (regexec): Fix type of `ret'. (Bug#9203)
11687 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
11689 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
11690 This is needed if max-image-size is a floating-point number.
11692 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
11694 * print.c (print_object): Print empty symbol as ##.
11696 * lread.c (read1): Read ## as empty symbol.
11698 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
11700 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
11701 setting frame foreground color (Bug#9175).
11702 (x_set_background_color): Likewise.
11704 * nsmenu.m (-setText): Size tooltip dimensions precisely to
11705 contents (Bug#9176).
11706 (EmacsTooltip -init): Remove bezels and add shadows to
11709 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
11710 or scroll bar (Bug#8470).
11712 * nsfont.m (nsfont_open): Remove assignment to voffset and
11713 unnecessary vars hshink, expand, hd, full_height, min_height.
11714 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
11716 * nsterm.h (nsfont_info): Remove voffset field.
11718 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
11720 Implement strike-through and overline on NextStep (Bug#8863).
11722 * nsfont.m (nsfont_open): Use underline position provided by font,
11723 instead of hard-coded value of 2.
11724 (nsfont_draw): Call ns_draw_text_decoration instead.
11726 * nsterm.h: Add declaration for ns_draw_text_decoration.
11728 * nsterm.m (ns_draw_text_decoration): New function for drawing
11729 underline, overline, and strike-through.
11730 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
11731 ns_draw_text_decoration. Change treatment of cursor drawing to
11732 accommodate underlining, etc.
11734 2011-07-28 Eli Zaretskii <eliz@gnu.org>
11736 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
11739 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
11741 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
11742 Without this fix, if a signal arrives just after memory fills up,
11743 'malloc' might be invoked reentrantly.
11745 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
11746 In other words, assume that every image size is allowed, on non-X
11747 hosts. This assumption is probably wrong, but it lets Emacs compile.
11749 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
11751 * regex.c (re_iswctype): Convert return values to boolean.
11753 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
11755 * xdisp.c (compute_display_string_pos): Don't use cached display
11756 string position if the buffer had its restriction changed.
11759 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
11761 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
11763 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
11765 Integer signedness and overflow and related fixes. (Bug#9079)
11767 * bidi.c: Integer size and overflow fixes.
11768 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
11769 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
11770 (bidi_cache_find_level_change, bidi_cache_ensure_space)
11771 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
11772 (bidi_find_other_level_edge):
11773 Use ptrdiff_t instead of EMACS_INT where either will do.
11774 This works better on 32-bit hosts configured --with-wide-int.
11775 (bidi_cache_ensure_space): Check for size-calculation overflow.
11776 Use % rather than repeated addition, for better worst-case speed.
11777 Don't set bidi_cache_size until after xrealloc returns, because it
11779 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
11780 (bidi_cache_ensure_space): Also check that the bidi cache size
11781 does not exceed that of the largest Lisp string or buffer. See Eli
11782 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
11784 * alloc.c (__malloc_size_t): Remove.
11785 All uses replaced by size_t. See Andreas Schwab's note
11786 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
11788 * image.c: Improve checking for integer overflow.
11789 (check_image_size): Assume that f is nonnull, since
11790 it is always nonnull in practice. This is one less thing to
11791 worry about when checking for integer overflow later.
11792 (x_check_image_size): New function, which checks for integer
11793 overflow issues inside X.
11794 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
11795 This removes the need for a memory_full check.
11796 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
11797 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
11798 (xbm_read_bitmap_data): Change locals back to 'int', since
11799 their values must fit in 'int'.
11800 (xpm_load_image, png_load, tiff_load):
11801 Invoke x_create_x_image_and_pixmap earlier,
11802 to avoid much needless work if the image is too large.
11803 (tiff_load): Treat overly large images as if
11804 x_create_x_image_and_pixmap failed, not as malloc failures.
11805 (gs_load): Use x_check_image_size.
11807 * gtkutil.c: Omit integer casts.
11808 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
11809 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
11811 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
11813 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
11814 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
11815 would wrongly return t on a 64-bit host.
11817 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
11818 The plain *_OVERFLOW macros run afoul of GCC bug 49705
11819 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
11820 and therefore cause GCC to emit a bogus diagnostic in some cases.
11822 * image.c: Integer signedness and overflow and related fixes.
11823 This is not an exhaustive set of fixes, but it's time to
11824 record what I've got.
11825 (lookup_pixel_color, check_image_size): Remove redundant decls.
11826 (check_image_size): Don't assume that arbitrary EMACS_INT values
11827 fit in 'int', or that arbitrary 'double' values fit in 'int'.
11828 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
11829 (tiff_load, imagemagick_load_image):
11830 Check for overflow in size calculations.
11831 (x_create_x_image_and_pixmap): Remove unnecessary test for
11832 xmalloc returning NULL; that can't happen.
11833 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
11834 (xpm_color_bucket): Use better integer hashing function.
11835 (xpm_cache_color): Don't possibly over-allocate memory.
11836 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
11837 (gif_memory_source):
11838 Use ptrdiff_t, not int or size_t, to record sizes.
11839 (png_load): Don't assume values greater than 2**31 fit in 'int'.
11840 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
11841 either works, as we prefer signed integers.
11842 (tiff_read_from_memory, tiff_write_from_memory):
11843 Return tsize_t, not size_t, since that's what the TIFF API wants.
11844 (tiff_read_from_memory): Don't fail simply because the read would
11845 go past EOF; instead, return a short read.
11846 (tiff_load): Omit no-longer-needed casts.
11847 (Fimagemagick_types): Don't assume size fits into 'int'.
11849 Improve hashing quality when configured --with-wide-int.
11850 * fns.c (hash_string): New function, taken from sxhash_string.
11851 Do not discard information about ASCII character case; this
11852 discarding is no longer needed.
11853 (sxhash-string): Use it. Change sig to match it. Caller changed.
11854 * lisp.h: Declare it.
11855 * lread.c (hash_string): Remove, since we now use fns.c's version.
11856 The fns.c version returns a wider integer if --with-wide-int is
11857 specified, so this should help the quality of the hashing a bit.
11859 * emacs.c: Integer overflow minor fix.
11860 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
11861 Define only if GNU_LINUX.
11862 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
11864 * dispnew.c: Integer signedness and overflow fixes.
11865 Remove unnecessary forward decls, that were a maintenance hassle.
11866 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
11868 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
11869 (scrolling_window): Use ptrdiff_t, not int, for byte count.
11870 (prepare_desired_row, line_draw_cost):
11871 Use int, not unsigned, where either works.
11872 (save_current_matrix, restore_current_matrix):
11873 Use ptrdiff_t, not size_t, where either works.
11874 (init_display): Check for overflow more accurately, and without
11875 relying on undefined behavior.
11877 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
11878 Remove, replacing with the new symbols in lisp.h. All uses changed.
11879 * fileio.c (make_temp_name):
11880 * filelock.c (lock_file_1, lock_file):
11881 * xdisp.c (message_dolog):
11882 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
11883 Use pMd etc. instead.
11884 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
11885 replacing the pWIDE etc. symbols removed from editfns.c.
11887 * keyboard.h (num_input_events): Now uintmax_t.
11888 This is (very slightly) less likely to mess up due to wraparound.
11891 * buffer.c: Integer signedness fixes.
11892 (alloc_buffer_text, enlarge_buffer_text):
11893 Use ptrdiff_t rather than size_t when either will do, as we prefer
11896 * alloc.c: Integer signedness and overflow fixes.
11897 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
11898 (__malloc_size_t): Default to size_t, not to int.
11899 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
11900 (Fgarbage_collect, mark_object_loop_halt, mark_object):
11901 Prefer ptrdiff_t to size_t when either would do, as we prefer
11903 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
11904 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
11905 Now const. Initialize with values that are in range even if char
11907 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
11908 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
11909 These functions do the right thing with sizes > 2**32.
11910 (check_depth): Now ptrdiff_t, not int.
11911 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
11912 Adjust to new way of storing sizes. Check for size overflow bugs
11914 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
11915 slightly wrong anyway, as it missed one instance of
11916 XMALLOC_OVERRUN_CHECK_OVERHEAD.
11917 (refill_memory_reserve): Omit needless cast to size_t.
11918 (mark_object_loop_halt): Mark as externally visible.
11920 * xselect.c: Integer signedness and overflow fixes.
11921 (Fx_register_dnd_atom, x_handle_dnd_message):
11922 Use ptrdiff_t, not size_t, since we prefer signed.
11923 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
11924 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
11925 x_dnd_atoms_size and x_dnd_atoms_length.
11927 * doprnt.c: Prefer signed to unsigned when either works.
11929 * doprnt.c (doprnt):
11931 * xdisp.c (vmessage):
11932 Use ptrdiff_t, not size_t, when using or implementing doprnt,
11933 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
11934 prefer signed arithmetic to avoid comparison confusion.
11935 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
11936 but is a bit tricky.
11938 Assume freestanding C89 headers, string.h, stdlib.h.
11939 * data.c, doprnt.c, floatfns.c, print.c:
11940 Include float.h unconditionally.
11941 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
11942 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
11943 * regex.c: Likewise for stddef.h, string.h.
11944 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
11945 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
11946 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
11947 (STDC_HEADERS): Remove obsolete defines.
11948 * sysdep.c: Include limits.h unconditionally.
11950 Assume support for memcmp, memcpy, memmove, memset.
11951 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
11952 * regex.c (memcmp, memcpy):
11953 Remove; we assume C89 now.
11955 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
11956 (__malloc_safe_bcopy): Remove; no longer needed.
11958 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
11959 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
11960 well either way, and we prefer signed to unsigned.
11962 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
11964 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
11965 closes the connection while we're reading (bug#9182).
11967 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
11969 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
11970 are specified (Bug#9168).
11972 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
11974 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
11975 Found by GCC static checking and --with-wide-int on a 32-bit host.
11977 2011-07-25 Eli Zaretskii <eliz@gnu.org>
11979 * xdisp.c (compute_display_string_pos): Fix logic of caching
11980 previous display string position. Initialize cached_prev_pos to
11981 -1. Fixes slow-down at the beginning of a buffer.
11983 2011-07-24 Eli Zaretskii <eliz@gnu.org>
11985 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
11986 for attrs[LFACE_FONTSET_INDEX].
11988 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
11990 * xml.c (parse_region): Remove unused local
11991 that was recently introduced.
11993 2011-07-23 Eli Zaretskii <eliz@gnu.org>
11995 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
11996 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
11998 * xdisp.c (move_it_in_display_line_to): Record the best matching
11999 position for TO_CHARPOS while scanning the line, and restore it on
12000 exit if none of the characters scanned was an exact match.
12001 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
12002 when exact match is impossible due to invisible text, and the
12003 lines are truncated.
12005 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
12007 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
12010 2011-07-22 Eli Zaretskii <eliz@gnu.org>
12012 Fix a significant slow-down of cursor motion with C-n, C-p,
12013 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
12014 auto-repeat under bidi redisplay in fontified buffers.
12015 * xdisp.c (compute_stop_pos_backwards): New function.
12016 (next_element_from_buffer): Call compute_stop_pos_backwards to
12017 find a suitable prev_stop when we find ourselves before
12019 (reseat): Don't look for prev_stop, as that could mean a very long
12021 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
12022 <cached_disp_overlay_modiff>: Cache for last found display string
12024 (compute_display_string_pos): Return the cached position if asked
12025 about the same buffer in the same area of character positions, and
12026 the buffer wasn't changed since the time the display string
12027 position was cached.
12029 2011-07-22 Eli Zaretskii <eliz@gnu.org>
12031 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
12032 is an integer, which is important for empty lines. (Bug#9149)
12034 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
12036 * frame.c (Fmodify_frame_parameters): In tty case, update the
12037 default face if necessary (Bug#4238).
12039 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
12041 * editfns.c (Fstring_to_char): No need to explain what a character
12042 is in the docstring (Bug#6576).
12044 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
12046 * xml.c (parse_region): Make sure we always return a tree.
12048 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
12050 * xml.c (parse_region): If a document contains only comments,
12053 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
12055 * xml.c (make_dom): Return comments, too.
12057 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
12060 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
12061 and the surrounding thread.
12062 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
12063 rather than fgets, and retry after EINTR. Otherwise, 'emacs
12064 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
12066 * s/openbsd.h (BROKEN_SIGIO): Define.
12067 * unexelf.c (unexec) [__OpenBSD__]:
12068 Don't update the .mdebug section of the Alpha COFF symbol table.
12070 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
12072 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
12075 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
12077 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
12078 This fixes some race conditions on the permissions of any newly
12081 * alloc.c (valid_pointer_p): Use pipe, not open.
12082 This fixes some permissions issues when debugging.
12084 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
12085 If fchown fails to set both uid and gid, try to set just gid,
12086 as that is sometimes allowed. Adjust the file's mode to eliminate
12087 setuid or setgid bits that are inappropriate if fchown fails.
12089 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
12091 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
12092 to compare Lisp_Objects.
12093 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
12094 global_gnutls_log_level, don't mistake it for a Lisp_Object.
12095 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
12097 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
12099 * lread.c (read_integer): Unread even EOF character.
12100 (read1): Likewise. Properly record start position of symbol.
12102 * lread.c (read1): Read `#:' as empty uninterned symbol if no
12103 symbol character follows.
12105 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
12107 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
12108 This works around a problem with the previous change to Fcopy_file.
12109 Recent glibc declares fchown with __attribute__((warn_unused_result)),
12110 and without this change, GCC might complain about discarding
12111 fchown's return value.
12113 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
12115 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).

12209 the iterator is before prev_stop.
12210 (init_iterator): Initialize bidi_p from the default value of

12728 Random fixes. E.g., (random) never returned negative values.
12729 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
12730 subseconds part to the entropy, as that's a bit more random.
12731 Prefer signed to unsigned, since the signedness doesn't matter and
12732 in general we prefer signed. When given a limit, use a
12733 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
12734 latter isn't right if USE_2_TAGS_FOR_INTS.
12735 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
12736 not 0..VALMASK. Don't discard "excess" bits that random () returns.

12760 error be more correct.
12762 * fns.c (Frequire): Remove the mention of the .gz files, since

12779 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
12780 Also (re)move comments that are misplaced or no longer relevant.

12881 * eval.c (struct backtrace): Simplify and port the data structure.
12882 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
12883 signed bit field, as this assumption is not portable and it makes
12884 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
12885 "char debug_on_exit : 1" as this is not portable either; instead,
12886 use the portable "unsigned int debug_on_exit : 1". Remove unused
12887 member evalargs. Remove obsolete comments about cc bombing out.

13051 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
13053 Integer and buffer overflow fixes (Bug#8873).
13055 * print.c (printchar, strout): Check for string overflow.
13056 (PRINTPREPARE, printchar, strout):
13057 Don't set size unless allocation succeeds.
13059 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
13060 for sizes. Check for string overflow more accurately.
13061 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
13063 * macros.c: Integer and buffer overflow fixes.
13064 * keyboard.h (struct keyboard.kbd_macro_bufsize):
13065 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):
13066 Use ptrdiff_t, not int, for sizes.
13067 Don't increment bufsize until after realloc succeeds.
13068 Check for size-calculation overflow.
13069 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
13071 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
13073 * lread.c: Integer overflow fixes.
13074 (read_integer): Radix is now EMACS_INT, not int,
13075 to improve quality of diagnostics for out-of-range radices.
13076 Calculate buffer size correctly for out-of-range radices.
13077 (read1): Check for integer overflow in radices, and in
13078 read-circle numbers.
13079 (read_escape): Avoid int overflow.
13080 (Fload, openp, read_buffer_size, read1)
13081 (substitute_object_recurse, read_vector, read_list, map_obarray):
13082 Use ptrdiff_t, not int, for sizes.

13095 (read_escape): Check for hex character overflow.
13097 2011-06-22 Leo Liu <sdl.web@gmail.com>
13099 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
13100 Move to minibuffer.el.
13102 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
13104 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
13105 The following patches are for when GLYPH_DEBUG && !XASSERT.
13106 * dispextern.h (trace_redisplay_p, dump_glyph_string):
13107 * dispnew.c (flush_stdout):
13108 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
13109 Mark as externally visible.
13110 * dispnew.c (check_window_matrix_pointers): Now static.
13111 * dispnew.c (window_to_frame_vpos):
13112 * xfns.c (unwind_create_frame):
13113 * xterm.c (x_check_font): Remove unused local.
13114 * scroll.c (CHECK_BOUNDS):
13115 * xfaces.c (cache_fache): Rename local to avoid shadowing.
13116 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
13117 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
13118 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
13119 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
13121 (debug_method_add): Use va_list and vsprintf rather than relying
13122 on undefined behavior with wrong number of arguments.
13123 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
13124 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
13125 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
13126 since we're not interested in debugging glyphs with old libraries.
13127 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
13128 GCC 4.6.0's static checking.
13130 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
13132 Integer overflow and signedness fixes (Bug#8873).

13141 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
13142 (x_create_bitmap_from_xpm_data):
13143 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
13144 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
13146 * xfaces.c (load_pixmap):
13147 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
13148 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
13149 (.bitmaps_last, struct x_output.icon_bitmap):
13150 Use ptrdiff_t, not int, for bitmap indexes.
13151 (x_allocate_bitmap_record): Check for size overflow.
13152 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
13154 Use ptrdiff_t, not int, for overlay counts.
13155 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
13156 * editfns.c (overlays_around, get_pos_property):
13157 * textprop.c (get_char_property_and_overlay):
13158 * xdisp.c (next_overlay_change, note_mouse_highlight):
13159 * xfaces.c (face_at_buffer_position):
13160 * buffer.c (OVERLAY_COUNT_MAX): New macro.
13161 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
13162 (Fnext_overlay_change, Fprevious_overlay_change)
13163 (mouse_face_overlay_overlaps, Foverlays_in):
13164 Use ptrdiff_t, not int, for sizes.
13165 (overlays_at, overlays_in): Check for size-calculation overflow.
13167 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
13169 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
13170 (x_session_initialize): Do not assume string length fits in int.
13172 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
13173 This is unlikely, but can occur if DPI is outlandish.
13175 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
13176 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
13178 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
13179 * xrdb.c (magic_file_p, search_magic_path):
13180 Omit last arg SUFFIX; it was always 0. All callers changed.
13181 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
13183 * xfont.c (xfont_match): Avoid need for strlen.
13185 * xfns.c: Don't assume strlen fits in int.
13186 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
13188 * xdisp.c (message_log_check_duplicate): Return intmax_t,
13189 not unsigned long, as we prefer signed integers. All callers changed.
13190 Detect integer overflow in repeat count.
13191 (message_dolog): Don't assume print length fits in 39 bytes.
13192 (display_mode_element): Don't assume strlen fits in int.
13194 * termcap.c: Don't assume sizes fit in int and never overflow.
13195 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
13196 (gobble_line): Check for size-calculation overflow.
13198 * minibuf.c (Fread_buffer):
13199 * lread.c (intern, intern_c_string):
13200 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
13201 Don't assume string length fits in int.
13203 * keyboard.c (parse_tool_bar_item):
13204 * gtkutil.c (style_changed_cb): Avoid need for strlen.
13206 * font.c: Don't assume string length fits in int.
13207 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
13208 Use ptrdiff_t, not int.
13209 (font_intern_prop): Don't assume string length fits in int.
13210 Don't assume integer property fits in fixnum.
13211 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
13213 * filelock.c: Fix some buffer overrun and integer overflow issues.
13214 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
13215 Reformulate so as not to need the command string.
13216 Invoke gzip -cd rather than gunzip, as it's more portable.
13217 (lock_info_type, lock_file_1, lock_file):
13218 Don't assume pid_t and time_t fit in unsigned long.
13219 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
13220 (current_lock_owner): Prefer signed type for sizes.
13221 Use memcpy, not strncpy, where memcpy is what is really wanted.
13222 Don't assume (via atoi) that time_t and pid_t fit in int.
13223 Check for time_t and/or pid_t out of range, e.g., via a network share.
13224 Don't alloca where an auto var works fine.
13226 * fileio.c: Fix some integer overflow issues.
13227 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
13228 Don't assume string length fits in int.
13229 (directory_file_name): Don't assume string length fits in long.
13230 (make_temp_name): Don't assume pid fits in int, or that its print
13231 length is less than 20.
13233 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
13235 * coding.c (make_subsidiaries): Don't assume string length fits in int.
13237 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
13239 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
13240 We prefer signed integers, even for size calculations.
13242 * emacs.c: Don't assume string length fits in 'int'.
13243 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
13244 (main): Don't invoke strlen when not needed.
13246 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
13247 (XD_DEBUG_MESSAGE): Don't waste a byte.
13249 * callproc.c (getenv_internal_1, getenv_internal)
13250 (Fgetenv_internal):
13251 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
13253 * lread.c (invalid_syntax): Omit length argument.
13254 All uses changed. This doesn't fix a bug, but it simplifies the
13255 code away from its former Hollerith-constant appearance, and it's
13256 one less 'int' to worry about when looking at integer-overflow issues.
13257 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
13259 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
13260 This didn't break anything, but it didn't help either.
13261 It's confusing to put a bogus integer in a place where the actual
13262 value does not matter.
13263 (LIST_END_P): Remove unused macro and its bogus comment.
13264 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
13266 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
13267 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
13269 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
13270 We prefer signed types, and the value cannot exceed the EMACS_INT
13271 range anyway (because otherwise the length would not be representable).
13272 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
13273 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
13274 This avoids a GCC warning when WIDE_EMACS_INT.
13276 * indent.c (sane_tab_width): New function.
13277 (current_column, scan_for_column, Findent_to, position_indentation)
13278 (compute_motion): Use it. This is just for clarity.
13279 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
13281 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
13283 * lisp.h (lint_assume): New macro.
13284 * composite.c (composition_gstring_put_cache):
13285 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
13287 * editfns.c, insdel.c:
13288 Omit unnecessary forward decls, to simplify future changes.
13290 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
13292 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
13294 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
13295 Use much-faster test for byte-length change.
13296 Don't assume string byte-length fits in 'int'.
13297 Check that character arg fits in 'int'.
13298 (mapcar1): Declare byte as byte, for clarity.
13300 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
13302 * fns.c (concat): Catch string overflow earlier.
13303 Do not rely on integer wraparound.
13305 * dispextern.h (struct it.overlay_strings_charpos)
13306 (struct it.selective): Now EMACS_INT, not int.
13307 * xdisp.c (forward_to_next_line_start)
13308 (back_to_previous_visible_line_start)
13309 (reseat_at_next_visible_line_start, next_element_from_buffer):
13310 Don't arbitrarily truncate the value of 'selective' to int.
13312 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
13314 * composite.c: Don't truncate sizes to 'int'.
13315 (composition_gstring_p, composition_reseat_it)
13316 (composition_adjust_point): Use EMACS_INT, not int.
13317 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
13318 not EMACS_UINT, for indexes.
13320 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
13322 * buffer.c: Include <verify.h>.
13323 (struct sortvec.priority, struct sortstr.priority):
13324 Now EMACS_INT, not int.
13325 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
13326 (struct sortstr.size, record_overlay_string)
13327 (struct sortstrlist.size, struct sortlist.used):
13328 Don't truncate size to int.
13329 (record_overlay_string): Check for size-calculation overflow.
13330 (init_buffer_once): Check at compile-time, not run-time.
13332 2011-06-22 Jim Meyering <meyering@redhat.com>
13334 Don't leak an XBM-image-sized buffer
13335 * image.c (xbm_load): Free the image buffer after using it.
13337 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
13340 * composite.c (find_automatic_composition): Omit needless 'return 0;'
13341 that Sun C diagnosed.
13342 * fns.c (secure_hash): Fix pointer signedness issue.
13343 * intervals.c (static_offset_intervals): New function.
13344 (offset_intervals): Use it.
13346 2011-06-21 Leo Liu <sdl.web@gmail.com>
13349 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
13352 * fns.c (secure_hash): Rename from crypto_hash_function and change
13353 the first arg to accept symbols.
13354 (Fsecure_hash): New primitive.
13355 (syms_of_fns): New symbols.
13357 2011-06-20 Deniz Dogan <deniz@dogan.se>
13359 * process.c (Fset_process_buffer): Clarify return value in
13362 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
13364 * dispnew.c (add_window_display_history): Use BVAR.
13366 * xdisp.c (debug_method_add): Use BVAR.
13367 (check_window_end, dump_glyph_matrix, dump_glyph)
13368 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
13370 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
13373 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
13374 check till after the cache is created in init_frame_faces.
13376 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
13378 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
13380 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
13382 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
13383 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
13384 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
13386 Improve buffer-overflow checking (Bug#8873).
13387 * fileio.c (Finsert_file_contents):
13388 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
13389 Remove the old (too-loose) buffer overflow checks.
13390 They weren't needed, since make_gap checks for buffer overflow.
13391 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
13392 The old code merely checked for Emacs fixnum overflow, and relied
13393 on undefined (wraparound) behavior. The new code avoids undefined
13394 behavior, and also checks for ptrdiff_t and/or size_t overflow.
13396 * editfns.c (Finsert_char): Don't dump core with very negative counts.
13397 Tune. Don't use wider integers than needed. Don't use alloca.
13398 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
13400 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
13402 * insdel.c, lisp.h (buffer_overflow): New function.
13403 (insert_from_buffer_1, replace_range, replace_range_2):
13404 * insdel.c (make_gap_larger):
13405 * editfns.c (Finsert_char):
13406 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
13408 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
13410 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
13412 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
13414 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
13415 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
13417 * fileio.c: Don't assume EMACS_INT fits in off_t.
13418 (emacs_lseek): New static function.
13419 (Finsert_file_contents, Fwrite_region): Use it.
13420 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
13422 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
13424 * fns.c: Don't overflow int when computing a list length.
13425 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
13426 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
13427 truncation on 64-bit hosts. Check for QUIT every
13428 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
13429 faster and is responsive enough.
13430 (Flength): Report an error instead of overflowing an integer.
13431 (Fsafe_length): Return a float if the value is not representable
13432 as a fixnum. This shouldn't happen except in contrived situations.
13433 (Fnthcdr, Fsort): Don't assume list length fits in int.
13434 (Fcopy_sequence): Don't assume vector length fits in int.
13436 * alloc.c: Check that resized vectors' lengths fit in fixnums.
13437 (header_size, word_size): New constants.
13438 (allocate_vectorlike): Don't check size overflow here.
13439 (allocate_vector): Check it here instead, since this is the only
13440 caller of allocate_vectorlike that could cause overflow.
13441 Check that the new vector's length is representable as a fixnum.
13443 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
13444 The previous code was bogus. For example, next_almost_prime (32)
13445 returned 39, which is undesirable as it is a multiple of 3; and
13446 next_almost_prime (24) returned 25, which is a multiple of 5 so
13447 why was the code bothering to check for multiples of 7?
13449 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
13451 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
13453 Variadic C functions now count arguments with ptrdiff_t.
13454 This partly undoes my 2011-03-30 change, which replaced int with size_t.
13455 Back then I didn't know that the Emacs coding style prefers signed int.
13456 Also, in the meantime I found a few more instances where arguments
13457 were being counted with int, which may truncate counts on 64-bit
13458 machines, or EMACS_INT, which may be unnecessarily wide.
13459 * lisp.h (struct Lisp_Subr.function.aMANY)
13460 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
13461 Arg counts are now ptrdiff_t, not size_t.
13462 All variadic functions and their callers changed accordingly.
13463 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
13464 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
13465 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
13466 * callint.c (Fcall_interactively): Check arg count for overflow,
13467 to avoid potential buffer overrun. Use signed char, not 'int',
13468 for 'varies' array, so that we needn't bother to check its size
13469 calculation for overflow.
13470 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
13471 * eval.c (apply_lambda):
13472 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
13473 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
13474 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
13476 * callint.c (Fcall_interactively): Don't use index var as event count.
13478 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
13479 * mem-limits.h (SIZE): Remove; no longer used.
13481 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
13483 Remove unnecessary casts.
13484 * xterm.c (x_term_init):
13485 * xfns.c (x_set_border_pixel):
13486 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
13487 These aren't needed now that we assume ANSI C.
13489 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
13490 It's more likely to cause problems (due to unsigned overflow)
13493 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
13495 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
13497 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
13499 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
13501 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
13503 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
13505 GLYPH_CODE_FACE returns EMACS_INT, not int.
13506 * dispextern.h (merge_faces):
13507 * xfaces.c (merge_faces):
13508 * xdisp.c (get_next_display_element, next_element_from_display_vector):
13509 Don't assume EMACS_INT fits in int.
13511 * character.h (CHAR_VALID_P): Remove unused parameter.
13512 * fontset.c, lisp.h, xdisp.c: All uses changed.
13514 * editfns.c (Ftranslate_region_internal): Omit redundant test.
13516 * fns.c (concat): Minor tuning based on overflow analysis.
13517 This doesn't fix any bugs. Use int to hold character, instead
13518 of constantly refetching from Emacs object. Use XFASTINT, not
13519 XINT, for value known to be a character. Don't bother comparing
13520 a single byte to 0400, as it's always less.
13522 * floatfns.c (Fexpt):
13523 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
13525 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
13528 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
13530 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
13531 Without this fix, on a 64-bit host (aset S 0 4294967386) would
13532 incorrectly succeed when S was a string, because 4294967386 was
13533 truncated before it was used.
13535 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
13536 Otherwise, an out-of-range integer could cause undefined behavior
13539 * composite.c: Use int, not EMACS_INT, for characters.
13540 (fill_gstring_body, composition_compute_stop_pos): Use int, not
13541 EMACS_INT, for values that are known to be in character range.
13542 This doesn't fix any bugs but is the usual style inside Emacs and
13543 may generate better code on 32-bit machines.
13545 Make sure a 64-bit char is never passed to ENCODE_CHAR.
13546 This is for reasons similar to the recent CHAR_STRING fix.
13547 * charset.c (Fencode_char): Check that character arg is actually
13548 a character. Pass an int to ENCODE_CHAR.
13549 * charset.h (ENCODE_CHAR): Verify that the character argument is no
13550 wider than 'int', as a compile-time check to prevent future regressions
13553 * character.c (char_string): Remove unnecessary casts.
13555 Make sure a 64-bit char is never passed to CHAR_STRING.
13556 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
13557 by silently ignoring the top 32 bits, allowing some values
13558 that were far too large to be valid characters.
13559 * character.h: Include <verify.h>.
13560 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
13561 arguments are no wider than unsigned, as a compile-time check
13562 to prevent future regressions in this area.
13564 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
13565 (Fsubst_char_in_region):
13567 * xdisp.c (decode_mode_spec_coding):
13568 Adjust to CHAR_STRING's new requirement.
13569 * editfns.c (Finsert_char, Fsubst_char_in_region):
13570 * fns.c (concat): Check that character args are actually
13571 characters. Without this test, these functions did the wrong
13572 thing with wildly out-of-range values on 64-bit hosts.
13574 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
13575 These casts should not be needed on 32-bit hosts, either.
13576 * keyboard.c (read_char):
13577 * lread.c (Fload): Remove casts to unsigned.
13579 * lisp.h (UNSIGNED_CMP): New macro.
13580 This fixes comparison bugs on 64-bit hosts.
13581 (ASCII_CHAR_P): Use it.
13582 * casefiddle.c (casify_object):
13583 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
13584 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
13585 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
13586 * dispextern.h (FACE_FROM_ID):
13587 * keyboard.c (read_char): Use UNSIGNED_CMP.
13589 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
13590 not to EMACS_INT, to avoid GCC warning.
13592 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
13594 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
13595 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
13596 isn't needed on 32-bit machines.
13598 * buffer.c (Fgenerate_new_buffer_name):
13599 Use EMACS_INT for count, not int.
13600 (advance_to_char_boundary): Return EMACS_INT, not int.
13602 * data.c (Qcompiled_function): Now static.
13604 * window.c (window_body_lines): Now static.
13606 * image.c (gif_load): Rename local to avoid shadowing.
13608 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
13609 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
13610 * alloc.c (make_save_value): Integer argument is now of type
13611 ptrdiff_t, not int.
13612 (mark_object): Use ptrdiff_t, not int.
13613 * lisp.h (pD): New macro.
13614 * print.c (print_object): Use it.
13616 * alloc.c: Use EMACS_INT, not int, to count objects.
13617 (total_conses, total_markers, total_symbols, total_vector_size)
13618 (total_free_conses, total_free_markers, total_free_symbols)
13619 (total_free_floats, total_floats, total_free_intervals)
13620 (total_intervals, total_strings, total_free_strings):
13621 Now EMACS_INT, not int. All uses changed.
13622 (Fgarbage_collect): Compute overall total using a double, so that
13623 integer overflow is less likely to be a problem. Check for overflow
13624 when converting back to an integer.
13625 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
13626 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
13627 These were 'int' variables that could overflow on 64-bit hosts;
13628 they were never used, so remove them instead of repairing them.
13629 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
13630 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
13631 Previously, this ceilinged at INT_MAX, but that doesn't work on
13633 (allocate_pseudovector): Don't use EMACS_INT when int would do.
13635 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
13636 (allocate_vectorlike): Check for ptrdiff_t overflow.
13637 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
13638 when a (possibly-narrower) signed value would do just as well.
13639 We prefer using signed arithmetic, to avoid comparison confusion.
13641 * alloc.c: Catch some string size overflows that we were missing.
13642 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
13643 for convenience in STRING_BYTES_MAX.
13644 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
13645 The definition here is exact; the one in lisp.h was approximate.
13646 (allocate_string_data): Check for string overflow. This catches
13647 some instances we weren't catching before. Also, it catches
13648 size_t overflow on (unusual) hosts where SIZE_MAX <= min
13649 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
13650 and ptrdiff_t and EMACS_INT are both 64 bits.
13652 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
13653 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
13654 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
13656 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
13658 * alloc.c (Fmake_string): Check for out-of-range init.
13660 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
13662 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
13664 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
13666 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
13667 xg_get_default_scrollbar_width.
13669 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
13670 (int_gtk_range_get_value): Move to the scroll bar part of the file.
13671 (style_changed_cb): Call update_theme_scrollbar_width and call
13672 x_set_scroll_bar_default_width and xg_frame_set_char_size for
13673 all frames (Bug#8505).
13674 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
13675 Call gtk_window_set_resizable if HAVE_GTK3.
13676 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
13677 and height if HAVE_GTK3 (Bug#8505).
13678 (scroll_bar_width_for_theme): New variable.
13679 (update_theme_scrollbar_width): New function.
13680 (xg_get_default_scrollbar_width): Move code to
13681 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
13682 (xg_initialize): Call update_theme_scrollbar_width.
13684 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
13686 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
13688 2011-06-12 Martin Rudalics <rudalics@gmx.at>
13690 * frame.c (make_frame): Call other_buffer_safely instead of
13693 * window.c (temp_output_buffer_show): Call display_buffer with
13694 second argument Vtemp_buffer_show_specifiers and reset latter
13695 immediately after the call.
13696 (Vtemp_buffer_show_specifiers): New variable.
13697 (auto_window_vscroll_p, next_screen_context_lines)
13698 (Vscroll_preserve_screen_position): Remove leading asterisks from
13701 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
13703 Fix minor problems found by GCC 4.6.0 static checking.
13704 * buffer.c (Qclone_number): Remove for now, as it's unused.
13705 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
13706 (record_buffer): Remove unused local.
13707 * frame.c (other_visible_frames, frame_buffer_list): Now static.
13708 (set_frame_buffer_list): Remove; unused.
13709 * frame.h (other_visible_frames): Remove decl.
13710 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
13711 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
13712 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
13714 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
13715 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
13716 Define only if HAVE_GPM.
13717 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
13718 (update_hints_inhibit): Remove; never set. All uses removed.
13719 * widgetprv.h (emacsFrameClassRec): Remove decl.
13720 * window.c (delete_deletable_window): Now returns void, since it
13721 wasn't returning anything.
13722 (compare_window_configurations): Remove unused locals.
13723 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
13724 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
13725 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
13726 the same widths as pointers. This follows up on the 2011-05-06 patch.
13727 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
13728 * xterm.h: Likewise.
13729 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.

13734 (LISP_H): Add lib/intprops.h.
13736 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
13738 * image.c (gif_load): Add animation frame delay to the metadata.
13739 (syms_of_image): Use DEFSYM. New symbol `delay'.
13741 2011-06-11 Martin Rudalics <rudalics@gmx.at>
13743 * window.c (delete_deletable_window): Re-add.
13744 (Fset_window_configuration): Rewrite to handle dead buffers and
13745 consequently deletable windows.
13746 (window_tree, Fwindow_tree): Remove. Supply functionality in
13748 (compare_window_configurations): Simplify code.
13750 2011-06-11 Andreas Schwab <schwab@linux-m68k.org>
13752 * image.c (imagemagick_load_image): Fix type mismatch.
13753 (Fimagemagick_types): Likewise.
13755 * window.h (replace_buffer_in_windows): Declare.
13757 2011-06-11 Martin Rudalics <rudalics@gmx.at>
13759 * buffer.c: New Lisp objects Qbuffer_list_update_hook and
13760 Qclone_number. Remove external declaration of Qdelete_window.
13761 (Fbuffer_list): Rewrite doc-string. Minor restructuring of
13763 (Fget_buffer_create, Fmake_indirect_buffer, Frename_buffer):
13764 Run Qbuffer_list_update_hook if allowed.
13765 (Fother_buffer): Rewrite doc-string. Major rewrite for new
13766 buffer list implementation.
13767 (other_buffer_safely): New function.
13768 (Fkill_buffer): Replace call to replace_buffer_in_all_windows by
13769 calls to replace_buffer_in_windows and
13770 replace_buffer_in_windows_safely. Run Qbuffer_list_update_hook
13772 (record_buffer): Inhibit quitting and rewrite using quittable
13773 functions. Run Qbuffer_list_update_hook if allowed.
13774 (Frecord_buffer, Funrecord_buffer): New functions.
13775 (switch_to_buffer_1, Fswitch_to_buffer): Remove.
13776 Move switch-to-buffer to window.el.
13777 (bury-buffer): Move to window.el.
13778 (Vbuffer_list_update_hook): New variable.
13780 * lisp.h (other_buffer_safely): Add prototype in buffer.c
13783 * window.h (resize_frame_windows): Move up in code.
13784 (Fwindow_frame): Remove EXFUN.
13785 (replace_buffer_in_all_windows): Remove prototype.
13786 (replace_buffer_in_windows_safely): Add prototype.
13788 * window.c: Declare Qdelete_window static again. Move down
13789 declaration of select_count.
13790 (Fnext_window, Fprevious_window): Rewrite doc-strings.
13791 (Fother_window): Move to window.el.
13792 (window_loop): Remove DELETE_BUFFER_WINDOWS and UNSHOW_BUFFER
13793 cases. Add REPLACE_BUFFER_IN_WINDOWS_SAFELY case.
13794 (Fdelete_windows_on, Freplace_buffer_in_windows): Move to
13796 (replace_buffer_in_windows): Implement by calling
13797 Qreplace_buffer_in_windows.
13798 (replace_buffer_in_all_windows): Remove with some functionality
13799 moved into replace_buffer_in_windows_safely.
13800 (replace_buffer_in_windows_safely): New function.
13801 (select_window_norecord, select_frame_norecord): Move in front
13802 of run_window_configuration_change_hook. Remove now obsolete
13804 (Fset_window_buffer): Rewrite doc-string.
13805 Call Qrecord_window_buffer.
13806 (keys_of_window): Move binding for other-window to window.el.
13808 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
13810 * dispextern.h (struct image): Replace data member, whose int_val
13811 and ptr_val fields were not used by anything, with a single
13814 * image.c (Fimage_metadata, make_image, mark_image, tiff_load)
13815 (gif_clear_image, gif_load, imagemagick_load_image)
13816 (gs_clear_image, gs_load): Callers changed.

14262 value of a `display' property is a "replacing spec".
14263 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
14264 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from

14294 * gnutls.c: Use Emacs's memory allocators.
14295 Without this change, the gnutls library would invoke malloc etc.
14296 directly, which causes problems on non-SYNC_INPUT hosts, and which
14297 runs afoul of improving memory_full behavior. (Bug#8761)
14298 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
14299 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
14300 xfree instead of the default malloc, realloc, free.
14301 (Fgnutls_boot): No need to check for memory allocation failure,
14302 since xmalloc does that for us.

14322 * lisp.h (struct Lisp_Hash_Table):
14323 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
14324 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
14325 for hashes and hash indexes, instead of 'unsigned' and 'int'.
14326 * alloc.c (allocate_vectorlike):
14327 Check for overflow in vector size calculations.
14328 * ccl.c (ccl_driver):
14329 Check for overflow when converting EMACS_INT to int.
14330 * fns.c, image.c: Remove unnecessary static decls that would otherwise
14331 need to be updated by these changes.
14332 * fns.c (make_hash_table, maybe_resize_hash_table):
14333 Check for integer overflow with large hash tables.
14334 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
14335 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
14336 (SXHASH_REDUCE): New macro.
14337 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
14338 Use it instead of discarding useful hash info with large hash values.
14339 (sxhash_float): New function.
14340 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
14341 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
14342 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
14343 Rewrite to use FIXNUM_BITS, as this simplifies things.
14344 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
14345 Adjust signatures to match updated version of code.
14346 (consing_since_gc): Now EMACS_INT, since a single hash table can
14347 use more than INT_MAX bytes.
14349 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
14351 Make it possible to build with GCC-4.6+ -O2 -flto.

14363 Update dependencies.
14365 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
14367 * data.c (init_data): Remove code for UTS, this system is not
14370 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
14372 Don't force ./temacs to start in terminal mode.
14374 * frame.c (make_initial_frame): Initialize faces in all cases, not
14375 only when CANNOT_DUMP is defined.
14376 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
14378 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
14380 * dispnew.c (add_window_display_history): Use const for the string
14381 pointer. Remove declaration, not needed.
14383 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
14385 Use 'inline', not 'INLINE'.
14386 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
14387 * alloc.c, fontset.c (INLINE): Remove.
14388 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
14389 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
14390 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
14391 * gmalloc.c (register_heapinfo): Use inline unconditionally.
14392 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
14394 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
14396 Make it possible to run ./temacs.
14398 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
14399 syms_of_callproc does the same thing. Remove test for
14400 "initialized", do it in the caller.
14401 * emacs.c (main): Avoid calling set_initial_environment when dumping.
14403 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
14405 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
14406 (read_minibuf): Use get_minibuffer.
14407 (syms_of_minibuf): Use DEFSYM.
14408 (Qmetadata): New var.
14409 * data.c (Qbuffer): Don't make it static.
14410 (syms_of_data): Use DEFSYM.
14412 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
14414 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
14415 (CCL_CODE_MIN): New macro.
14417 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
14419 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
14421 * eval.c (Qdebug): Now static.
14422 * lisp.h (Qdebug): Remove decl. This reverts a part of the
14423 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
14424 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
14426 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
14428 * image.c: Various fixes to ImageMagick code comments.
14429 (Fimagemagick_types): Doc fix.
14431 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
14433 Minor fixes prompted by GCC 4.6.0 warnings.
14435 * xselect.c (converted_selections, conversion_fail_tag): Now static.
14437 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
14438 (x_clipboard_manager_save_all): Move extern decl to ...
14439 * xterm.h: ... here, so that it can be checked for consistency.
14441 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
14443 * xselect.c (x_clipboard_manager_save_frame)
14444 (x_clipboard_manager_save_all): New functions.
14445 (Fx_clipboard_manager_save): Lisp function deleted.
14447 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
14448 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
14450 * xterm.h: Update prototype.
14452 2011-05-28 William Xu <william.xwl@gmail.com>
14454 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
14455 exiting (Bug#8239).
14457 2011-05-28 Jim Meyering <meyering@redhat.com>
14459 Avoid a sign-extension bug in crypto_hash_function.
14460 * fns.c (to_uchar): Define.
14461 (crypto_hash_function): Use it to convert some newly-signed
14462 variables to unsigned, to avoid sign-extension bugs. For example,
14463 without this change, (md5 "truc") would evaluate to
14464 45723a2aff78ff4fff7fff1114760e62 rather than the expected
14465 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
14466 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
14468 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
14470 Integer overflow fixes.
14472 * dbusbind.c: Serial number integer overflow fixes.
14473 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
14474 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
14475 to hold a serial number that is too large for a fixnum.
14476 (Fdbus_method_return_internal, Fdbus_method_error_internal):
14477 Check for serial numbers out of range. Decode any serial number
14478 that was so large that it became a float. (Bug#8722)
14480 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
14481 (Fdbus_call_method, Fdbus_call_method_asynchronously):
14482 Use XFASTINT rather than XUINT when numbers are nonnegative.
14483 (xd_append_arg, Fdbus_method_return_internal):
14484 (Fdbus_method_error_internal): Likewise. Also, for unsigned
14485 arguments, check that Lisp number is nonnegative, rather than
14486 silently wrapping negative numbers around. (Bug#8722)
14487 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
14490 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
14492 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
14494 ccl: Add integer overflow checks.
14495 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
14496 (IN_INT_RANGE): New macros.
14497 (ccl_driver): Use them to check for integer overflow when
14498 decoding a CCL program. Many of the new checks are whether XINT (x)
14499 fits in int; it doesn't always, on 64-bit hosts. The new version
14500 doesn't catch all possible integer overflows, but it's an
14501 improvement. (Bug#8719)
14503 * alloc.c (make_event_array): Use XINT, not XUINT.
14504 There's no need for unsigned here.
14506 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
14507 This follows up to the 2011-05-06 change that substituted uintptr_t
14508 for EMACS_INT. This case wasn't caught back then.
14510 Rework Fformat to avoid integer overflow issues.
14511 * editfns.c: Include <float.h> unconditionally, as it's everywhere
14512 now (part of C89). Include <verify.h>.
14513 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
14514 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
14515 (Fformat): Avoid the prepass trying to compute sizes; it was only
14516 approximate and thus did not catch overflow reliably. Instead, walk
14517 through the format just once, formatting and computing sizes as we go,
14518 checking for integer overflow at every step, and allocating a larger
14519 buffer as needed. Keep track separately whether the format is
14520 multibyte. Keep only the most-recently calculated precision, rather
14521 than them all. Record whether each argument has been converted to
14522 string. Use EMACS_INT, not int, for byte and char and arg counts.
14523 Support field widths and precisions larger than INT_MAX. Avoid
14524 sprintf's undefined behavior with conversion specifications such as %#d
14525 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
14526 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
14527 formatting out-of-range floating point numbers with int
14528 formats. (Bug#8668)
14530 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
14532 * data.c: Avoid integer truncation in expressions involving floats.
14533 * data.c: Include <intprops.h>.
14534 (arith_driver): When there's an integer overflow in an expression
14535 involving floating point, convert the integers to floating point
14536 so that the resulting value does not suffer from catastrophic
14537 integer truncation. For example, on a 64-bit host (* 4
14538 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
14539 Do not rely on undefined behavior after integer overflow.
14541 merge count_size_as_multibyte, parse_str_to_multibyte
14542 * character.c, character.h (count_size_as_multibyte):
14543 Rename from parse_str_to_multibyte; all uses changed.
14544 Check for integer overflow.
14545 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
14546 since it's now a duplicate of the other. This is more of
14547 a character than a buffer op, so better that it's in character.c.
14548 * fns.c, print.c: Adjust to above changes.
14550 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
14552 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
14554 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
14556 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
14557 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
14558 (x_clipboard_manager_save): Now static.
14559 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
14561 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
14562 (crypto_hash_function): Now static.
14563 Fix pointer signedness problems. Avoid unnecessary initializations.
14565 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
14567 * termhooks.h (Vselection_alist): Make it terminal-local.
14569 * terminal.c (create_terminal): Initialize it.
14571 * xselect.c: Support for clipboard managers.
14572 (Vselection_alist): Move to termhooks.h as terminal-local var.
14573 (LOCAL_SELECTION): New macro.
14574 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
14575 (symbol_to_x_atom): Remove gratuitous arg.
14576 (x_handle_selection_request, lisp_data_to_selection_data)
14577 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
14578 (x_own_selection, x_get_local_selection, x_convert_selection):
14579 New arg, specifying work frame. Use terminal-local Vselection_alist.
14580 (some_frame_on_display): Delete unused function.
14581 (Fx_own_selection_internal, Fx_get_selection_internal)
14582 (Fx_disown_selection_internal, Fx_selection_owner_p)
14583 (Fx_selection_exists_p): New optional frame arg.
14584 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
14585 (x_handle_selection_clear): Don't treat other terminals with the
14586 same keyboard specially. Use the terminal-local Vselection_alist.
14587 (x_clear_frame_selections): Use Frun_hook_with_args.
14589 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
14591 * xterm.h: Add support for those atoms.
14593 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
14595 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
14596 (converted_selections, conversion_fail_tag): New global variables.
14597 (x_selection_request_lisp_error): Free the above.
14598 (x_get_local_selection): Remove unnecessary code.
14599 (x_reply_selection_request): Args changed; handle arbitrary array
14600 of converted selections stored in converted_selections.
14601 Separate the XChangeProperty and SelectionNotify steps.
14602 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
14603 (x_convert_selection): New function.
14604 (x_handle_selection_event): Simplify.
14605 (x_get_foreign_selection): Don't ignore incoming requests while
14606 waiting for an answer; this will fail when we implement
14607 SAVE_TARGETS, and seems unnecessary anyway.
14608 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
14609 (Vx_sent_selection_functions): Doc fix.
14611 2011-05-26 Leo Liu <sdl.web@gmail.com>
14613 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
14615 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14617 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
14619 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
14620 for fringe update if it has periodic bitmap.
14621 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
14622 and fringe_bitmap_periodic_p.
14624 * fringe.c (get_fringe_bitmap_data): New function.
14625 (draw_fringe_bitmap_1, update_window_fringes): Use it.
14626 (update_window_fringes): Record periodicity of fringe bitmap in glyph
14627 row. Mark glyph row for fringe update if periodicity changed.
14629 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
14630 for fringe update unless it has periodic bitmap.
14632 2011-05-25 Kenichi Handa <handa@m17n.org>
14634 * xdisp.c (get_next_display_element): Set correct it->face_id for
14635 a static composition.

14649 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
14650 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
14651 Remove macros that are defined and never used.
14652 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
14654 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
14656 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
14657 (Fx_get_selection_internal): Minor cleanup.
14658 (Fx_own_selection_internal): Rename arguments for consistency with
14661 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>

14683 report_file_error introduced by the change from 2011-05-07.
14685 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
14687 * systime.h (Time): Define only if emacs is defined.
14688 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
14689 where the include path doesn't have X11/X.h by default. See
14690 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
14692 2011-05-20 Kenichi Handa <handa@m17n.org>
14694 * composite.c (find_automatic_composition): Fix previous change.
14696 2011-05-20 Glenn Morris <rgm@gnu.org>
14698 * lisp.mk: New file, split from Makefile.in.
14699 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
14700 (shortlisp): Remove.
14701 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
14703 2011-05-19 Glenn Morris <rgm@gnu.org>
14705 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
14706 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
14707 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
14708 (lisp): Set the order to that of loadup.el.
14709 (shortlisp): Make it a copy of $lisp.
14710 (SOME_MACHINE_LISP): Remove.
14711 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
14712 Use just $shortlisp, not $SOME_MACHINE_LISP too.
14714 2011-05-18 Kenichi Handa <handa@m17n.org>
14716 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
14717 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
14718 (find_automatic_composition): Mostly rewrite for efficiency.
14720 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
14722 * makefile.w32-in: Update dependencies.
14724 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
14726 * menu.c: Include limits.h (fixes the MS-Windows build broken by
14727 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
14729 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
14731 Fix some integer overflow issues, such as string length overflow.
14733 * insdel.c (count_size_as_multibyte): Check for string overflow.
14735 * character.c (lisp_string_width): Check for string overflow.
14736 Use EMACS_INT, not int, for string indexes and lengths; in
14737 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
14738 the resulting string length overflows an EMACS_INT; instead,
14739 report a string overflow if no precision given. When checking for
14740 precision exhaustion, use a check that cannot possibly have
14741 integer overflow. (Bug#8675)
14742 * character.h (lisp_string_width): Adjust to new signature.
14744 * alloc.c (string_overflow): New function.
14745 (Fmake_string): Use it. This doesn't change behavior, but saves
14746 a few bytes and will simplify future changes.
14747 * character.c (string_escape_byte8): Likewise.
14748 * lisp.h (string_overflow): New decl.
14750 Fixups, following up to the user-interface timestamp change.
14751 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
14752 for UI timestamps, instead of unsigned long.
14753 * msdos.c (mouse_get_pos): Likewise.
14754 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
14755 * w32gui.h (Time): Define by including "systime.h" rather than by
14756 declaring it ourselves. (Bug#8664)
14758 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
14759 * image.c (clear_image_cache): Likewise.
14761 * term.c (term_mouse_position): Don't assume time_t wraparound.
14763 Be more systematic about user-interface timestamps.
14764 Before, the code sometimes used 'Time', sometimes 'unsigned long',
14765 and sometimes 'EMACS_UINT', to represent these timestamps.
14766 This change causes it to use 'Time' uniformly, as that's what X uses.
14767 This makes the code easier to follow, and makes it easier to catch
14768 integer overflow bugs such as Bug#8664.
14769 * frame.c (Fmouse_position, Fmouse_pixel_position):
14770 Use Time, not unsigned long, for user-interface timestamps.
14771 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
14772 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
14773 * keyboard.h (last_event_timestamp): Likewise.
14774 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
14775 * menu.h (xmenu_show): Likewise.
14776 * term.c (term_mouse_position): Likewise.
14777 * termhooks.h (struct input_event.timestamp): Likewise.
14778 (struct terminal.mouse_position_hook): Likewise.
14779 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
14780 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
14781 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
14782 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
14783 what it was before.
14784 * menu.h, termhooks.h: Include "systime.h", for Time.
14786 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
14787 Don't assume that the difference between two unsigned long values
14788 can fit into an integer. At this point, we know button_down_time
14789 <= event->timestamp, so the difference must be nonnegative, so
14790 there's no need to cast the result if double-click-time is
14791 nonnegative, as it should be; check that it's nonnegative, just in
14792 case. This bug is triggered when events are more than 2**31 ms
14793 apart (about 25 days). (Bug#8664)
14795 * xselect.c (last_event_timestamp): Remove duplicate decl.
14796 (x_own_selection): Remove needless cast to unsigned long.
14798 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
14799 that always fit in int. Use a sentinel instead of a counter, to
14800 avoid a temp and to allay GCC's concerns about possible int overflow.
14801 * frame.h (struct frame): Use int for menu_bar_items_used
14802 instead of EMACS_INT, since it always fits in int.
14804 * menu.c (grow_menu_items): Check for int overflow.
14806 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
14808 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
14809 Before, the code was not consistent. These values cannot exceed
14810 2**31 - 1 so there's no need to make them unsigned.
14811 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
14812 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
14813 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
14815 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
14817 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
14818 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
14819 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
14820 presumably because the widths might not match.
14822 * window.c (size_window): Avoid needless test at loop start.
14824 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
14826 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
14828 2011-05-12 Drew Adams <drew.adams@oracle.com>
14830 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
14832 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14834 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
14835 `width' to `bar_area_x' and `bar_area_width', respectively.
14836 (x_scroll_run): Take account of fringe background extension.
14838 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
14839 Rename local vars `left' and `width' to `bar_area_x' and
14840 `bar_area_width', respectively.
14841 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
14842 background extension.
14844 2011-05-10 Jim Meyering <meyering@redhat.com>
14846 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
14848 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
14850 * image.c (Finit_image_library): Return t for built-in image types,
14851 like pbm and xbm. (Bug#8640)
14853 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
14855 * w32menu.c (set_frame_menubar): Fix submenu allocation.
14857 2011-05-07 Eli Zaretskii <eliz@gnu.org>
14859 * w32console.c (Fset_screen_color): Doc fix.
14860 (Fget_screen_color): New function.
14861 (syms_of_ntterm): Defsubr it.
14863 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
14864 unlink the temporary file if Fcall_process didn't create it in the
14866 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
14867 child process will be redirected to a file specified with `:file'.
14868 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
14869 cue to call_process_cleanup not to close that handle.
14871 2011-05-07 Ben Key <bkey76@gmail.com>
14873 * makefile.w32-in: The bootstrap-temacs rule now makes use of
14874 one of two shell specific rules, either bootstrap-temacs-CMD or
14875 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
14876 to the previous implementation of the bootstrap-temacs rule.
14877 The bootstrap-temacs-CMD rule is similar to the previous
14878 implementation of the bootstrap-temacs rule except that it
14879 makes use of the ESC_CFLAGS variable instead of the CFLAGS
14882 These changes, along with some changes to nt/configure.bat,
14883 nt/gmake.defs, and nt/nmake.defs, are required to extend my
14884 earlier fix to add support for --cflags and --ldflags options
14885 that include quotes so that it works whether make uses cmd or
14888 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
14890 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
14891 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
14893 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
14894 a string. Handle both cases.
14895 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
14896 (Fdbus_register_method): Use Qinvalid_function.
14898 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
14900 * makefile.w32-in: Update dependencies.
14901 (LISP_H): Add inttypes.h and stdin.h.
14902 (PROCESS_H): Add unistd.h.
14904 2011-05-06 Eli Zaretskii <eliz@gnu.org>
14906 * lread.c: Include limits.h (fixes the MS-Windows build broken by
14907 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
14909 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
14911 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
14913 * term.c (vfatal): Remove stray call to va_end.
14914 It's not needed and the C Standard doesn't allow it here anyway.
14916 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
14917 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
14919 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
14922 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
14924 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
14926 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
14928 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
14930 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
14932 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
14933 * charset.c (Fdefine_charset_internal): Don't initialize
14934 charset.code_space[15]. The value was garbage, on hosts with
14935 32-bit int (Bug#8600).
14937 * lread.c (read_integer): Be more consistent with string-to-number.
14938 Use string_to_number to do the actual conversion; this avoids
14939 rounding errors and fixes some other screwups. Without this fix,
14940 for example, #x1fffffffffffffff was misread as -2305843009213693952.
14941 (digit_to_number): Move earlier, for benefit of read_integer.
14942 Return -1 if the digit is out of range for the base, -2 if it is
14943 not a digit in any supported base. (Bug#8602)
14945 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
14947 * dispnew.c (scrolling_window): Return 1 if we scrolled,
14948 to match comment at start of function. This also removes a
14949 GCC warning about overflow in a 32+64-bit port.
14951 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
14953 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
14954 Reported by Stefan Monnier in
14955 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
14956 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
14957 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
14959 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
14960 (EMACS_UINTPTR): Likewise, with uintptr_t.
14962 * lisp.h: Prefer 64-bit EMACS_INT if available.
14963 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
14964 on 32-bit hosts that have 64-bit int, so that they can access
14966 However, temporarily disable this change unless the temporary
14967 symbol WIDE_EMACS_INT is defined.
14969 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
14971 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
14972 This removes an assumption that EMACS_INT and long are the same
14973 width as pointers. The assumption is true for Emacs porting targets
14974 now, but we want to make other targets possible.
14975 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
14976 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
14977 In the rest of the code, change types of integers that hold casted
14978 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
14979 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
14980 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
14981 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
14982 No need to cast type when ORing.
14983 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
14984 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
14985 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
14986 assume EMACS_INT is the same width as char *.
14987 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
14988 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
14989 Remove no-longer-needed casts.
14990 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
14991 (xg_tool_bar_help_callback, xg_make_tool_item):
14992 Use EMACS_INTPTR to hold an integer
14993 that will be cast to void *; this can avoid a GCC warning
14994 if EMACS_INT is not the same width as void *.
14995 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
14996 * xdisp.c (display_echo_area_1, resize_mini_window_1):
14997 (current_message_1, set_message_1):
14998 Use a local to convert to proper width without a cast.
14999 * xmenu.c (dialog_selection_callback): Likewise.
15001 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
15002 Also, don't assume VALBITS / RAND_BITS is less than 5,
15003 and don't rely on undefined behavior when shifting a 1 left into
15005 * lisp.h (get_random): Change signature to match.
15007 * lread.c (hash_string): Use size_t, not int, for hash computation.
15008 Normally we prefer signed values; but hashing is special, because
15009 it's better to use unsigned division on hash table sizes so that
15010 the remainder is nonnegative. Also, size_t is the natural width
15011 for hashing into memory. The previous code used 'int', which doesn't
15012 retain enough info to hash well into very large tables.
15013 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
15015 * dbusbind.c: Don't possibly lose pointer info when converting.
15016 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
15017 Use XPNTR rather than XHASH, so that the high-order bits of
15018 the pointer aren't lost when converting through void *.
15020 * eval.c (Fautoload): Don't double-shift a pointer.
15022 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
15024 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
15026 * gnutls.c (DEF_GNUTLS_FN):
15027 * image.c (DEF_IMGLIB_FN): Make function pointers static.
15029 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
15031 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
15034 2011-05-05 Eli Zaretskii <eliz@gnu.org>
15036 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
15037 New version that can reserve upto 2GB of heap space.
15039 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
15041 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
15043 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
15045 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
15046 `gnutls_certificate_set_x509_key_file'.
15048 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
15050 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
15051 Update dependencies.
15053 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
15055 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
15056 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
15057 Remove unused parameter `fildes'.
15058 * process.c (read_process_output, send_process): Don't pass it.
15060 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
15062 Fix previous change: the library cache is defined in w32.c.
15063 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
15064 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
15066 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
15068 Implement dynamic loading of GnuTLS on Windows.
15070 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
15071 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
15072 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
15075 * gnutls.c (Qgnutls_dll): Define.
15076 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
15077 (gnutls_*): Declare function pointers.
15078 (init_gnutls_functions): New function to initialize function pointers.
15079 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
15080 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
15081 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
15082 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
15083 (emacs_gnutls_write, emacs_gnutls_read)
15084 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
15085 (Fgnutls_available_p): New function.
15086 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
15087 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
15088 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
15090 * image.c: Include w32.h.
15091 (Vimage_type_cache): Delete.
15092 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
15093 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
15094 (w32_delayed_load): Move to w32.c.
15096 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
15098 * w32.c (QCloaded_from, Vlibrary_cache): Define.
15099 (w32_delayed_load): Move from image.c. When loading a library, record
15100 its filename in the :loaded-from property of the library id.
15101 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
15102 Initialize and staticpro them.
15103 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
15105 * process.c: Include lisp.h before w32.h, not after.
15106 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
15107 instead of gnutls_record_check_pending.
15109 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
15111 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
15113 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
15114 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
15117 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
15119 * xterm.c (x_set_frame_alpha): Do not set property on anything
15120 else than FRAME_X_OUTER_WINDOW (Bug#8608).
15122 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
15124 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
15126 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
15128 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
15129 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)
15130 (Qgnutls_e_invalid_session, Qgnutls_e_not_ready_for_handshake)

15135 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
15136 (Qgnutls_bootprop_callbacks_verify): Make static.
15138 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
15140 * callproc.c: Indentation fixup.
15142 * sysdep.c (wait_for_termination_1): Make static.
15143 (wait_for_termination, interruptible_wait_for_termination):
15144 Move after wait_for_termination_1.
15146 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
15148 * sysdep.c (interruptible_wait_for_termination): New function
15149 which is like wait_for_termination, but allows keyboard
15152 * callproc.c (Fcall_process): Add (:file "file") as an option for
15154 (Fcall_process_region): Ditto.
15156 2011-04-30 Eli Zaretskii <eliz@gnu.org>
15158 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
15159 rather than `XVECTOR (FOO)->size'.
15161 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of

15165 2011-04-21 Eli Zaretskii <eliz@gnu.org>
15167 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
15168 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
15169 of MOST_POSITIVE_FIXNUM. (Bug#8528)
15171 * coding.c (coding_alloc_by_realloc): Error out if destination
15172 will grow beyond MOST_POSITIVE_FIXNUM.
15173 (decode_coding_emacs_mule): Abort if there isn't enough place in
15174 charbuf for the composition carryover bytes. Reserve an extra
15175 space for up to 2 characters produced in a loop.
15176 (decode_coding_iso_2022): Abort if there isn't enough place in
15177 charbuf for the composition carryover bytes.
15179 2011-04-21 Eli Zaretskii <eliz@gnu.org>
15181 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
15182 aborting when %lld or %lll format is passed.
15183 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
15184 %llo or %llx format is passed. (Bug#8545)
15186 * window.c (window_scroll_line_based): Use a marker instead of
15187 simple variables to record original value of point. (Bug#7952)
15189 * doprnt.c (doprnt): Fix the case where a multibyte sequence
15190 produced by %s or %c overflows available buffer space. (Bug#8545)
15192 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
15194 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
15195 (SIZE_MAX): Move defn after all includes, as they might #define it.
15197 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
15199 * w32.c (init_environment): Warn about defaulting HOME to C:\.
15201 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
15203 * keyboard.c (Qdelayed_warnings_hook): Define.
15204 (command_loop_1): Run `delayed-warnings-hook'
15205 if Vdelayed_warnings_list is non-nil.
15206 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
15207 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
15209 2011-04-28 Eli Zaretskii <eliz@gnu.org>
15211 * doprnt.c (doprnt): Don't return value smaller than the buffer
15212 size if the message was truncated. (Bug#8545).
15214 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
15216 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
15217 (Fx_window_property): #if-0 the whole functions, not just the bodies.
15219 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
15221 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
15223 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
15225 * makefile.w32-in: Update dependencies.
15227 2011-04-27 Eli Zaretskii <eliz@gnu.org>
15229 Improve `doprnt' and its usage. (Bug#8545)
15230 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
15231 `format_end'. Remove support for %l as a conversion specifier.
15232 Don't use xrealloc. Improve diagnostics when the %l size modifier
15233 is used. Update the commentary.
15235 * eval.c (verror): Simplify calculation of size_t.
15237 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
15240 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
15242 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
15245 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
15247 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
15248 This makes this file independent of the recent pseudovector change.
15250 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
15252 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
15254 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
15255 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
15256 Remove unused local.
15257 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
15259 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
15260 GCC 4.6.0 optimizes based on type-based alias analysis.
15261 For example, if b is of type struct buffer * and v of type struct
15262 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
15263 != &v->size, and therefore "v->size = 1; b->size = 2; return
15264 v->size;" must therefore return 1. This assumption is incorrect
15265 for Emacs, since it type-puns struct Lisp_Vector * with many other
15266 types. To fix this problem, this patch adds a new type struct
15267 vectorlike_header that documents the constraints on layout of vectors
15268 and pseudovectors, and helps optimizing compilers not get fooled
15269 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
15270 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
15271 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
15273 (XSETPVECTYPE): Rewrite in terms of new macro.
15274 (XSETPVECTYPESIZE): New macro, specifying both type and size.
15275 This is a bit clearer, and further avoids the possibility of
15276 undesirable aliasing.
15277 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
15278 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
15279 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
15280 since Lisp_Subr is a special case (no "next" field).
15281 (ASIZE): Now uses header.size rather than size.
15282 All previous uses of XVECTOR (foo)->size replaced to use this macro,
15283 to avoid the hassle of writing XVECTOR (foo)->header.size.
15284 (struct vectorlike_header): New type.
15285 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
15286 object, to help avoid aliasing.
15287 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
15288 (SUBRP): Likewise, since Lisp_Subr is a special case.
15289 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
15290 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
15291 (struct Lisp_Hash_Table): Combine first two members into a single
15292 struct vectorlike_header member. All uses of "size" and "next" members
15293 changed to be "header.size" and "header.next".
15294 * buffer.h (struct buffer): Likewise.
15295 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
15296 * frame.h (struct frame): Likewise.
15297 * process.h (struct Lisp_Process): Likewise.
15298 * termhooks.h (struct terminal): Likewise.
15299 * window.c (struct save_window_data, struct saved_window): Likewise.
15300 * window.h (struct window): Likewise.
15301 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
15302 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
15303 * buffer.c (init_buffer_once): Likewise.
15304 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
15306 * process.c (Fformat_network_address): Use local var for size,
15309 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
15311 Make the Lisp reader and string-to-float more consistent (Bug#8525)
15312 * data.c (atof): Remove decl; no longer used or needed.
15313 (digit_to_number): Move to lread.c.
15314 (Fstring_to_number): Use new string_to_number function, to be
15315 consistent with how the Lisp reader treats infinities and NaNs.
15316 Do not assume that floating-point numbers represent EMACS_INT
15317 without losing information; this is not true on most 64-bit hosts.
15318 Avoid double-rounding errors, by insisting on integers when
15319 parsing non-base-10 numbers, as the documentation specifies.
15320 * lisp.h (string_to_number): New decl, replacing ...
15321 (isfloat_string): Remove.
15322 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
15323 (read1): Do not accept +. and -. as integers; this
15324 appears to have been a coding error. Similarly, do not accept
15325 strings like +-1e0 as floating point numbers. Do not report
15326 overflow for integer overflows unless the base is not 10 which
15327 means we have no simple and reliable way to continue.
15328 Break out the floating-point parsing into a new
15329 function string_to_number, so that Fstring_to_number parses
15330 floating point numbers consistently with the Lisp reader.
15331 (digit_to_number): Move here from data.c. Make it static inline.
15332 (E_CHAR, EXP_INT): Remove, replacing with ...
15333 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
15334 (string_to_number): New function, replacing isfloat_string.
15335 This function checks for valid syntax and produces the resulting
15336 Lisp float number too. Rework it so that string-to-number
15337 no longer mishandles examples like "1.0e+". Use strtoumax,
15338 so that overflow for non-base-10 numbers is reported only when
15339 there's no portable and simple way to convert to floating point.
15341 * textprop.c (set_text_properties_1): Rewrite for clarity,
15342 and to avoid GCC warning about integer overflow.
15344 * intervals.h (struct interval): Use EMACS_INT for members
15345 where EMACS_UINT might cause problems. See
15346 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
15347 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
15348 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
15350 (offset_intervals): Tell GCC not to worry about length overflow
15351 when negating a negative length.
15353 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
15354 (overrun_check_free): Likewise.
15356 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
15357 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
15360 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
15361 (gnutls_make_error): Rename local to avoid shadowing.
15362 (gnutls_emacs_global_deinit): ifdef out; not used.
15363 (Fgnutls_boot): Use const for pointer to readonly storage.
15364 Comment out unused local. Fix pointer signedness problems.
15366 * lread.c (openp): Don't stuff size_t into an 'int'.
15367 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
15368 about possible signed overflow.
15370 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
15371 (GDK_KEY_g): Don't define if already defined.
15372 (xg_prepare_tooltip): Avoid pointer signedness problem.
15373 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
15375 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
15376 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
15378 * xfns.c (Fx_window_property): Simplify a bit,
15379 to make a bit faster and to avoid GCC 4.6.0 warning.
15380 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
15382 * fns.c (internal_equal): Don't assume size_t fits in int.
15384 * alloc.c (compact_small_strings): Tighten assertion a little.
15386 Replace pEd with more-general pI, and fix some printf arg casts.
15387 * lisp.h (pI): New macro, generalizing old pEd macro to other
15388 conversion specifiers. For example, use "...%"pI"d..." rather
15389 than "...%"pEd"...".
15390 (pEd): Remove. All uses replaced with similar uses of pI.
15391 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
15392 * alloc.c (check_pure_size): Don't overflow by converting size to int.
15393 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
15394 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
15395 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
15396 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
15397 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
15399 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
15400 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
15401 * print.c (safe_debug_print, print_object): Likewise.
15402 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
15404 Use pI instead of if-then-else-abort. Use %p to avoid casts,
15405 avoiding the 0 flag, which is not portable.
15406 * process.c (Fmake_network_process): Use pI to avoid cast.
15407 * region-cache.c (pp_cache): Likewise.
15408 * xdisp.c (decode_mode_spec): Likewise.
15409 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
15410 behavior on 64-bit hosts with printf arg.
15411 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
15412 (x_stop_queuing_selection_requests): Likewise.
15413 (x_get_window_property): Don't truncate byte count to an 'int'
15416 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
15417 here, since it parses constructs like leading '-' and spaces,
15418 which are not wanted; and it overflows with large numbers.
15419 Instead, simply match F[0-9]+, which is what is wanted anyway.
15421 * alloc.c: Remove unportable assumptions about struct layout.
15422 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
15423 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
15424 (allocate_vectorlike, make_pure_vector): Use the new macros,
15425 plus offsetof, to remove unportable assumptions about struct layout.
15426 These assumptions hold on all porting targets that I know of, but
15427 they are not guaranteed, they're easy to remove, and removing them
15428 makes further changes easier.
15430 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
15431 This doesn't fix a bug but makes the code clearer.
15432 (string_overrun_cookie): Now const. Use initializers that
15433 don't formally overflow signed char, to avoid warnings.
15434 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
15435 can cause Emacs to crash when string overrun checking is enabled.
15436 (allocate_buffer): Don't assume sizeof (struct buffer) is a
15437 multiple of sizeof (EMACS_INT); it need not be, if
15438 alignof(EMACS_INT) < sizeof (EMACS_INT).
15439 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
15441 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
15443 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
15445 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
15447 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
15448 supposed to be handshaking. (Bug#8556)
15449 Reported by Paul Eggert <eggert@cs.ucla.edu>.
15451 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
15453 * lisp.h (Qdebug): List symbol.
15454 * eval.c (Qdebug): Restore global linkage.
15455 * keyboard.c (debug-on-event): New variable.
15456 (handle_user_signal): Break into debugger when debug-on-event
15457 matches the current signal symbol.
15459 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
15461 * alloc.c (check_sblock, check_string_bytes)
15462 (check_string_free_list): Convert to standard C.
15464 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
15466 * w32.c (emacs_gnutls_push): Fix typo.
15468 2011-04-25 Eli Zaretskii <eliz@gnu.org>
15470 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
15471 "cast to pointer from integer of different size".
15473 Improve doprnt and its use in verror. (Bug#8545)
15474 * doprnt.c (doprnt): Document the set of format control sequences
15475 supported by the function. Use SAFE_ALLOCA instead of always
15478 * eval.c (verror): Don't limit the buffer size at size_max-1, that
15479 is one byte too soon. Don't use xrealloc; instead xfree and
15482 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
15484 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
15487 * gnutls.c: Renamed global_initialized to
15488 gnutls_global_initialized. Added internals for the
15489 :verify-hostname-error, :verify-error, and :verify-flags
15490 parameters of `gnutls-boot' and documented those parameters in the
15491 docstring. Start callback support.
15492 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
15493 unless a fatal error occurred. Call gnutls_alert_send_appropriate
15494 on error. Return error code.
15495 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
15496 (emacs_gnutls_read): Likewise.
15497 (Fgnutls_boot): Return handshake error code.
15498 (emacs_gnutls_handle_error): New function.
15499 (wsaerror_to_errno): Likewise.

15504 * w32.c (emacs_gnutls_pull): New function for GnuTLS on Woe32.
15505 (emacs_gnutls_push): Likewise.
15507 2011-04-24 Claudio Bley <claudio.bley@gmail.com> (tiny change)

15510 buffered some data internally if no FDs are set for TLS
15513 * makefile.w32-in (OBJ2): Add gnutls.$(O).

15531 <menu_help_message, prev_menu_help_message>: Constify.
15532 (IT_menu_make_room): menu->help_text is now `const char **';
15535 * msdos.h (XMenuActivate, XMenuAddSelection): Adjust prototypes
15536 to changes in oldXMenu/XMenu.h from 2011-04-16.
15537 (struct XMenu): Declare `help_text' `const char **'.

15554 changes in globals.h immediately force recompilation.
15555 (TAGS): Depend on $(CURDIR)/m/intel386.h and
15556 $(CURDIR)/s/ms-w32.h.
15557 (TAGS-gmake): Scan $(CURDIR)/m/intel386.h and $(CURDIR)/s/ms-w32.h.

15560 (syms_of_character): Don't defsubr it.
15561 <char-direction-table>: Deleted.
15563 2011-04-23 Eli Zaretskii <eliz@gnu.org>
15565 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
15566 * doprnt.c: Include limits.h.
15567 (SIZE_MAX): New macro.
15568 (doprnt): Return a size_t value. 2nd arg is now size_t.
15569 Many local variables are now size_t instead of int or unsigned.
15570 Improve overflow protection. Support `l' modifier for integer
15571 conversions. Support %l conversion. Don't assume an EMACS_INT
15572 argument for integer conversions and for %c.
15574 * lisp.h (doprnt): Restore prototype.
15576 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
15577 $(SRC)/character.h.
15579 * Makefile.in (base_obj): Add back doprnt.o.
15581 * deps.mk (doprnt.o): Add back prerequisites.
15582 (callint.o): Depend on character.h.
15584 * eval.c (internal_lisp_condition_case): Include the handler
15585 representation in the error message.
15586 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
15587 when breaking from the loop.
15589 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
15591 * callint.c (Fcall_interactively): When displaying error message
15592 about invalid control letter, pass the character's codepoint, not
15593 a pointer to its multibyte form. Improve display of the character
15594 in octal and display also its hex code.
15596 * character.c (char_string): Use %x to display the (unsigned)
15597 codepoint of an invalid character, to avoid displaying a bogus
15600 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
15601 `error', not SYMBOL_NAME itself.
15603 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
15604 character arguments to `error'.

15822 * process.c (send_process): Adjust to the new signatures of
15823 emacs_write and emacs_gnutls_write. Do not attempt to store

16155 * buffer.c (buffer_count): Remove unused var.

16159 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
16160 * dispextern.h (bidi_dump_cached_states): Remove, since it's
16161 exported only to the debugger.

16164 * atimer.h (run_all_atimers): Remove; not exported.
16166 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
16167 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
16168 was inaccessible from Lisp.
16169 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
16170 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
16172 alloc.c: Import and export fewer symbols, and remove unused items.
16173 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING

16189 (mark_backtrace): Define only if BYTE_MARK_STACK.
16190 * xdisp.c (message_enable_multibyte): Now static.
16192 Declare Lisp_Object Q* variables to be 'static' if not exported.
16193 This makes it easier for human readers (and static analyzers)
16194 to see whether these variables are used from other modules.
16195 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:

16205 Remove decls of unexported vars.
16206 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
16208 * lisp.h (DEFINE_FUNC): Make sname 'static'.
16210 Make Emacs functions such as Fatom 'static' by default.
16211 This makes it easier for human readers (and static analyzers)
16212 to see whether these functions can be called from other modules.
16213 DEFUN now defines a static function. To make the function external
16214 so that it can be used in other C modules, use the new macro DEFUE.
16215 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
16216 (Finit_image_library):
16217 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):

16219 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
16220 Remove decls, since these functions are now static.
16221 (Funintern, Fget_internal_run_time): New decls, since these functions
16222 were already external.
16224 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:

16231 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
16232 Mark functions with DEFUE instead of DEFUN,
16233 if they are used in other modules.
16234 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
16235 decls for now-static functions.
16236 * buffer.h (Fdelete_overlay): Remove decl.
16237 * callproc.c (Fgetenv_internal): Mark as internal.
16238 * composite.c (Fremove_list_of_text_properties): Remove decl.

16246 * image.c (Finit_image_library): New forward static decl.
16247 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
16248 * intervals.h (Fprevious_property_change):
16249 (Fremove_list_of_text_properties): Remove decls.
16250 * keyboard.c (Fthis_command_keys): Remove decl.
16251 (Fcommand_execute): New forward static decl.

16267 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
16269 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
16272 2011-04-13 Eli Zaretskii <eliz@gnu.org>
16274 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
16275 when at ZV. (Bug#8487)
16277 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
16279 * charset.c (Fclear_charset_maps): Use xfree instead of free.

16285 * xsettings.c (read_and_apply_settings): Likewise.
16287 * alloc.c (overrun_check_malloc, overrun_check_realloc)
16288 (overrun_check_free): Protoize.
16290 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
16292 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
16293 since callers should never pass a negative size.
16294 Change the signature to match that of plain 'read' and 'write'; see
16295 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
16296 * lisp.h: Update prototypes of emacs_write and emacs_read.
16298 2011-04-11 Eli Zaretskii <eliz@gnu.org>
16300 * xdisp.c (redisplay_window): Don't try to determine the character
16301 position of the scroll margin if the window start point w->startp
16302 is outside the buffer's accessible region. (Bug#8468)
16304 2011-04-10 Eli Zaretskii <eliz@gnu.org>
16306 Fix write-region and its subroutines for buffers > 2GB.
16307 * fileio.c (a_write, e_write): Modify declaration of arguments and
16308 local variables to support buffers larger than 2GB.
16309 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
16311 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
16312 argument, local variables, and return value.
16314 * lisp.h: Update prototypes of emacs_write and emacs_read.
16316 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
16318 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
16320 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
16322 Fix more problems found by GCC 4.6.0's static checks.
16324 * xdisp.c (vmessage): Use a better test for character truncation.
16326 * charset.c (load_charset_map): <, not <=, for optimization,
16327 and to avoid potential problems with integer overflow.
16328 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
16329 * casetab.c (set_identity, shuffle): Likewise.
16330 * editfns.c (Fformat): Likewise.
16331 * syntax.c (skip_chars): Likewise.
16333 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
16334 This also lets GCC 4.6.0 generate slightly better loop code.
16336 * callint.c (Fcall_interactively): <, not <=, for optimization.
16337 (Fcall_interactively): Count the number of arguments produced,
16338 not the number of arguments given. This is simpler and lets GCC
16339 4.6.0 generate slightly better code.
16341 * ftfont.c: Distingish more carefully between FcChar8 and char.
16342 The previous code passed unsigned char * to a functions like
16343 strlen and xstrcasecmp that expect char *, which does not
16344 conform to the C standard.
16345 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
16346 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
16347 char * when the C standard requires it.
16349 * keyboard.c (read_char): Remove unused var.
16351 * eval.c: Port to Windows vsnprintf (Bug#8435).
16352 Include <limits.h>.
16353 (SIZE_MAX): Define if the headers do not.
16354 (verror): Do not give up if vsnprintf returns a negative count.
16355 Instead, grow the buffer. This ports to Windows vsnprintf, which
16356 does not conform to C99. Problem reported by Eli Zaretskii.
16357 Also, simplify the allocation scheme, by avoiding the need for
16358 calling realloc, and removing the ALLOCATED variable.
16360 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
16362 Remove invocations of doprnt, as Emacs now uses vsnprintf.
16363 But keep the doprint source code for now, as we might revamp it
16364 and use it again (Bug#8435).
16365 * lisp.h (doprnt): Remove.
16366 * Makefile.in (base_obj): Remove doprnt.o.
16367 * deps.mk (doprnt.o): Remove.
16369 error: Print 32- and 64-bit integers portably (Bug#8435).
16370 Without this change, on typical 64-bit hosts error ("...%d...", N)
16371 was used to print both 32- and 64-bit integers N, which relied on
16372 undefined behavior.
16373 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
16374 * lisp.h (error, verror): Mark as printf-like functions.
16375 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
16376 Report overflow in size calculations when allocating printf buffer.
16377 Do not truncate output string at its first null byte.
16378 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
16379 Truncate the output at a character boundary, since vsnprintf does not
16381 * charset.c (check_iso_charset_parameter): Convert internal
16382 character to string before calling 'error', since %c now has the
16384 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
16385 overflow when computing char to be passed to 'error'. Do not
16386 pass Lisp_Object to 'error'; pass the integer instead.
16387 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
16388 formatted with plain %d.
16390 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
16392 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
16394 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
16396 * xterm.c (x_catch_errors): Remove duplicate declaration.
16398 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
16400 * xdisp.c, lisp.h (message_nolog): Remove; unused.
16402 2011-04-10 Jim Meyering <meyering@redhat.com>
16404 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
16405 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
16406 return ssize_t not "int", and use size_t as the buffer length.
16407 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
16408 * gnutls.h: Update declarations.
16409 * process.c (read_process_output): Use ssize_t, to match.
16410 (send_process): Likewise.
16412 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
16414 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
16416 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
16418 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
16419 Use unsigned char, to match FcChar8 type definition.
16421 * xterm.c (handle_one_xevent):
16422 * xmenu.c (create_and_show_popup_menu):
16423 * xselect.c (x_decline_selection_request)
16424 (x_reply_selection_request): Avoid type-punned deref of X events.
16426 2011-04-09 Eli Zaretskii <eliz@gnu.org>
16428 Fix some uses of `int' instead of EMACS_INT.
16429 * search.c (string_match_1, fast_string_match)
16430 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
16431 (scan_buffer, find_next_newline_no_quit)
16432 (find_before_next_newline, search_command, Freplace_match)
16433 (Fmatch_data): Make some `int' variables be EMACS_INT.
16435 * xdisp.c (display_count_lines): 3rd argument and return value now
16436 EMACS_INT. All callers changed.
16437 (pint2hrstr): Last argument is now EMACS_INT.
16439 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
16440 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
16441 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)

16452 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
16453 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
16455 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
16456 (encode_invocation_designation): Last argument P_NCHARS is now
16458 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
16459 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
16461 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
16464 * ccl.c (Fccl_execute_on_string): Declare some variables
16467 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
16469 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).

16482 instead of using internal_with_output_to_temp_buffer.
16483 (Qhelp_form_show): New var.
16484 (syms_of_keyboard): Use DEFSYM macro.
16486 * print.c (internal_with_output_to_temp_buffer): Function deleted.

16501 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
16503 Fix more problems found by GCC 4.6.0's static checks.
16505 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
16507 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
16509 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
16511 * xdisp.c (vmessage): Mark as a printf-like function.
16513 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.

16517 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
16518 printf-like functions.
16519 (tiff_load): Add casts to remove these marks before passing them
16520 to system-supplied API.
16522 * eval.c (Fsignal): Remove excess argument to 'fatal'.
16524 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
16525 This avoids several warnings with gcc -Wstrict-overflow.
16526 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
16527 directly, rather than having caller test rule sign. This avoids
16528 some unnecessary tests.
16529 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
16530 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
16531 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
16533 * xfont.c (xfont_text_extents): Remove var that was set but not used.
16534 (xfont_open): Avoid unnecessary tests.
16536 * composite.c (composition_gstring_put_cache): Use unsigned integer.
16538 * composite.h, composite.c (composition_gstring_put_cache):
16539 Use EMACS_INT, not int, for length.
16541 * composite.h (COMPOSITION_DECODE_REFS): New macro,
16542 breaking out part of COMPOSITION_DECODE_RULE.
16543 (COMPOSITION_DECODE_RULE): Use it.
16544 * composite.c (get_composition_id): Remove unused local vars,
16545 by using the new macro.
16547 * textprop.c (set_text_properties_1): Change while to do-while,
16548 since the condition is always true at first.
16550 * intervals.c (graft_intervals_into_buffer): Mark var as used.
16551 (interval_deletion_adjustment): Return unsigned value.
16554 * process.c (list_processes_1, create_pty, read_process_output):
16555 (exec_sentinel): Remove vars that were set but not used.
16556 (create_pty): Remove unnecessary "volatile"s.
16557 (Fnetwork_interface_info): Avoid possibility of int overflow.
16558 (read_process_output): Do adaptive read buffering even if carryover.
16559 (read_process_output): Simplify nbytes computation if buffered.
16561 * bytecode.c (exec_byte_code): Rename local to avoid shadowing.
16563 * syntax.c (scan_words): Remove var that was set but not used.
16564 (update_syntax_table): Use unsigned instead of int.
16566 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
16567 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
16568 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
16570 * print.c (print_error_message): Avoid int overflow.
16572 * font.c (font_list_entities): Redo for clarity,
16573 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
16575 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
16576 (font_score): Avoid potential overflow in diff calculation.
16578 * fns.c (substring_both): Remove var that is set but not used.
16579 (sxhash): Redo loop for clarity and to avoid wraparound warning.
16581 * eval.c (funcall_lambda): Rename local to avoid shadowing.
16583 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
16584 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
16585 can always succeed if overflow has undefined behavior.
16587 * search.c (boyer_moore, wordify): Remove vars set but not used.
16588 (wordify): Omit three unnecessary tests.
16590 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
16591 All callers changed. This avoids the need for an unused var.
16593 * casefiddle.c (casify_region): Remove var that is set but not used.
16595 * dired.c (file_name_completion): Remove var that is set but not used.
16597 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
16599 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
16600 (Finsert_file_contents): Remove unnecessary code checking fd.
16602 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
16603 Check for integer overflow on size calculations.
16605 * buffer.c (Fprevious_overlay_change): Remove var that is set
16608 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
16609 Remove vars that are set but not used.
16610 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
16611 (timer_check_2): Mark vars as initialized.
16613 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
16615 * image.c (lookup_image): Remove var that is set but not used.
16616 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
16618 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
16619 that are set but not used.
16621 * xfns.c (make_invisible_cursor): Don't return garbage
16622 if XCreateBitmapFromData fails (Bug#8410).
16624 * xselect.c (x_get_local_selection, x_handle_property_notify):
16625 Remove vars that are set but not used.
16627 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
16628 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
16630 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
16631 Remove var that is set but not used.
16632 (scroll_bar_windows_size): Now size_t, not int.
16633 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
16634 Check for overflow.
16636 * xfaces.c (realize_named_face): Remove vars that are set but not used.
16637 (map_tty_color) [!defined MSDOS]: Likewise.
16639 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
16641 * coding.c: Remove vars that are set but not used.
16642 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
16643 All callers changed.
16644 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
16645 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
16646 (decode_coding_charset): Remove vars that are set but not used.
16648 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
16649 that is set but not used.
16651 * print.c (print_object): Remove var that is set but not used.
16653 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
16654 The gnulib version avoids calling malloc in the usual case,
16655 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
16656 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
16657 * filelock.c (current_lock_owner): Likewise.
16658 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
16659 * sysdep.c: Include allocator.h, careadlinkat.h.
16660 (emacs_no_realloc_allocator): New static constant.
16661 (emacs_readlink): New function.
16662 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
16663 ../lib/careadlinkat.h.
16665 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
16667 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
16668 first non-nil return value).
16670 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
16672 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
16673 if not defined (Bug#8403).
16675 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
16677 * xdisp.c (display_count_lines): Remove parameter `start',
16678 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
16679 (get_char_face_and_encoding): Remove parameter `multibyte_p',
16680 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

16682 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
16683 and thereabouts. All callers changed.
16684 (get_per_char_metric): Remove parameter `f', unused since
16685 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
16687 2011-04-02 Jim Meyering <meyering@redhat.com>
16689 do not dereference NULL upon failed strdup
16690 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
16691 (ns_get_family): Likewise.
16693 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
16695 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
16697 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
16699 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
16702 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
16704 Add lexical binding.
16706 * window.c (Ftemp_output_buffer_show): New fun.
16707 (Fsave_window_excursion):
16708 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
16710 * lread.c (lisp_file_lexically_bound_p): New function.
16711 (Fload): Bind Qlexical_binding.
16712 (readevalloop): Remove `evalfun' arg.
16713 Bind Qinternal_interpreter_environment.
16714 (Feval_buffer): Bind Qlexical_binding.
16715 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
16717 (syms_of_lread): Declare `lexical-binding'.
16719 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
16721 * keyboard.c (eval_dyn): New fun.
16722 (menu_item_eval_property): Use it.
16724 * image.c (parse_image_spec): Use Ffunctionp.
16726 * fns.c (concat, mapcar1): Accept byte-code-functions.
16728 * eval.c (Fsetq): Handle lexical vars.
16729 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
16730 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
16731 (FletX, Flet): Obey lexical binding.
16732 (Fcommandp): Handle closures.
16733 (Feval): New `lexical' arg.
16734 (eval_sub): New function extracted from Feval. Use it almost
16735 everywhere where Feval was used. Look up vars in lexical env.
16737 (Ffunctionp): Move from subr.el.
16738 (Ffuncall): Handle closures.
16739 (apply_lambda): Remove `eval_flags'.
16740 (funcall_lambda): Handle closures and new byte-code-functions.
16741 (Fspecial_variable_p): New function.
16742 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
16743 but without exporting it to Lisp.
16745 * doc.c (Fdocumentation, store_function_docstring):
16746 * data.c (Finteractive_form): Handle closures.
16748 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
16751 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
16753 (exec_byte_code): New function extracted from Fbyte_code to handle new
16754 calling convention for byte-code-functions. Add new byte-codes.
16756 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
16758 * alloc.c (Fmake_symbol): Init new `declared_special' field.
16760 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
16762 * xdisp.c (redisplay_internal): Fix prototype.
16764 2011-03-31 Eli Zaretskii <eliz@gnu.org>
16766 * xdisp.c (SCROLL_LIMIT): New macro.
16767 (try_scrolling): Use it when setting scroll_limit.
16768 Limit scrolling to 100 screen lines.
16769 (redisplay_window): Even when falling back on "recentering",
16770 position point in the window according to scroll-conservatively,
16771 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
16773 (try_scrolling): When point is above the window, allow searching
16774 as far as scroll_max, or one screenful, to compute vertical
16775 distance from PT to the scroll margin position. This prevents
16776 try_scrolling from unnecessarily failing when
16777 scroll-conservatively is set to a value slightly larger than the
16778 window height. Clean up the case of PT below the margin at bottom
16779 of window: scroll_max can no longer be INT_MAX. When aggressive
16780 scrolling is in use, don't let point enter the opposite scroll
16781 margin as result of the scroll.
16782 (syms_of_xdisp) <scroll-conservatively>: Document the
16783 threshold of 100 lines for never-recentering scrolling.
16785 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
16787 * dispextern.h (move_it_by_lines):
16788 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
16789 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
16790 (message_log_check_duplicate): Remove parameters `prev_bol' and
16791 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
16792 (redisplay_internal): Remove parameter `preserve_echo_area',
16793 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
16795 * indent.c (Fvertical_motion):
16796 * window.c (window_scroll_pixel_based, Frecenter):
16797 Don't pass `need_y_p' to `move_it_by_lines'.
16799 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
16801 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
16802 steal a few bits to be more compact.
16803 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
16804 Remove unneeded casts.
16806 * bytecode.c (Fbyte_code): CAR and CDR can GC.
16808 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
16810 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
16811 binding" message (bug#7967).
16813 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
16815 Fix more problems found by GCC 4.6.0's static checks.
16817 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
16818 Remove unused local var.
16820 * editfns.c (Fmessage_box): Remove unused local var.
16822 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
16823 (note_mode_line_or_margin_highlight, note_mouse_highlight):
16824 Omit unused local vars.
16825 * window.c (shrink_windows): Omit unused local var.
16826 * menu.c (digest_single_submenu): Omit unused local var.
16827 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
16828 Omit unused local var.
16830 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
16831 Don't assume string length fits in int.
16832 (keyremap_step, read_key_sequence): Use size_t for sizes.
16833 (read_key_sequence): Don't check last_real_key_start redundantly.
16835 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
16836 instead of alloca (Bug#8344).
16838 * eval.c (Fbacktrace): Don't assume nargs fits in int.
16839 (Fbacktrace_frame): Don't assume nframes fits in int.
16841 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
16843 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
16846 * term.c (produce_glyphless_glyph): Remove unnecessary test.
16848 * cm.c (calccost): Turn while-do into do-while, for clarity.
16850 * keyboard.c (syms_of_keyboard): Use the same style as later
16851 in this function when indexing through an array. This also
16852 works around GCC bug 48267.
16854 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
16856 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
16858 * chartab.c (sub_char_table_ref_and_range): Redo for slight
16859 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
16861 * keyboard.c, keyboard.h (num_input_events): Now size_t.
16862 This avoids undefined behavior on integer overflow, and is a bit
16863 more convenient anyway since it is compared to a size_t variable.
16865 Variadic C functions now count arguments with size_t, not int.
16866 This avoids an unnecessary limitation on 64-bit machines, which
16867 caused (substring ...) to crash on large vectors (Bug#8344).
16868 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
16869 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

16877 * fns.c (concat): Likewise.
16878 * frame.c (x_set_frame_parameters): Likewise.
16879 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
16880 0 if not found, not -1. All callers changed.
16882 * alloc.c (garbage_collect): Don't assume stack size fits in int.
16883 (stack_copy_size): Now size_t, not int.
16884 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
16886 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
16888 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
16889 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
16890 All callers changed.
16892 * lisp.h (multibyte_char_to_unibyte):
16893 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
16894 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

16898 * keymap.c (push_key_description):
16899 * search.c (Freplace_match):
16900 * xdisp.c (message_dolog, set_message_1): All callers changed.
16902 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
16904 * keyboard.c (safe_run_hook_funcall): New function.
16905 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
16906 don't set the hook to nil, but remove the offending function instead.
16907 (Qcommand_hook_internal): Remove, unused.
16908 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
16909 Vcommand_hook_internal.
16911 * eval.c (enum run_hooks_condition): Remove.
16912 (funcall_nil, funcall_not): New functions.
16913 (run_hook_with_args): Call each function through a `funcall' argument.
16914 Remove `cond' argument, now redundant.
16915 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
16916 (Frun_hook_with_args_until_failure): Adjust accordingly.
16917 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
16919 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
16921 * dispextern.h (string_buffer_position): Remove declaration.
16923 * print.c (strout): Remove parameter `multibyte', unused since
16924 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
16926 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',

17090 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
17092 (command_loop_1): Use Frun_hooks. Call safe_run_hooks

17095 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
17097 Fix more problems found by GCC 4.5.2's static checks.
17099 * coding.c (encode_coding_raw_text): Avoid unnecessary test
17100 the first time through the loop, since we know p0 < p1 then.
17101 This also avoids a gcc -Wstrict-overflow warning.
17103 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
17104 leading to a memory leak, possible in functions like
17105 load_charset_map_from_file that can allocate an unbounded number
17106 of objects (Bug#8318).
17108 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
17109 that could (at least in theory) be that large.
17111 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
17112 This is less likely to overflow, and avoids undefined behavior if
17113 overflow does occur. All callers changed. Use strtoul to scan
17114 for the unsigned long integer.
17115 (pint2hrstr): Simplify and tune code slightly.

17131 * process.c (Fmake_network_process): Use socklen_t, not int,
17132 where POSIX says socklen_t is required in portable programs.
17133 This fixes a porting bug on hosts like 64-bit HP-UX, where
17134 socklen_t is wider than int (Bug#8277).
17135 (Fmake_network_process, server_accept_connection):
17136 (wait_reading_process_output, read_process_output):
17139 * process.c: Rename or move locals to avoid shadowing.

17149 Make tparam.h and terminfo.c consistent.
17150 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
17151 Include tparam.h instead, since it declares them.
17152 * cm.h (PC): Remove extern decl; tparam.h now does this.
17153 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
17154 * terminfo.c: Include tparam.h, to check interfaces.
17155 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
17156 (tparam): Adjust signature to match interface in tparam.h;
17157 this removes some undefined behavior. Check that outstring and len
17158 are zero, which they always are with Emacs.
17159 * tparam.h (PC, BC, UP): New extern decls.
17161 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
17162 (xftfont_open): Rename locals to avoid shadowing.

17180 (composition_update_it): Mark var as initialized.
17181 (find_automatic_composition): Mark vars as initialized,
17182 with a FIXME (Bug#8290).

17188 (BUF_DEC_POS): Be more systematic about renaming local temporaries
17189 to avoid shadowing.

17201 Fix pointer signedness.
17202 (alsa_choose_format): Remove unused local var.
17203 (wav_play): Initialize a variable to 0, to prevent undefined
17204 behavior (Bug#8278).
17206 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
17208 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
17210 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
17211 clobbering (Bug#8298).
17212 * sysdep.c (sys_subshell): Likewise.
17213 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
17215 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
17216 This should get cleaned up, so that child_setup has the
17217 same signature on all platforms.
17219 * callproc.c (call_process_cleanup): Now static.
17220 (relocate_fd): Rename locals to avoid shadowing.
17222 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
17224 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
17225 not to be necessary, and produces flickering.
17227 2011-03-20 Glenn Morris <rgm@gnu.org>
17229 * config.in: Remove file.
17231 2011-03-20 Juanma Barranquero <lekktu@gmail.com>

17380 (GC_STRING_CHARS): Remove; not used.
17381 (Fmemory_limit): Cast sbrk's returned value to char *.
17383 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
17384 avoids undefined behavior in theory.
17386 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
17388 Use functions, not macros, for up- and down-casing (Bug#8254).
17389 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
17390 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
17391 to use the following functions instead of these macros.
17392 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
17393 EMACS_INT, since callers assume the returned value fits in int.
17394 (upcase1): Likewise, for UPCASE_TABLE.
17395 (uppercasep, lowercasep, upcase): New static inline functions.
17396 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for
17397 the race-condition problem in the old DOWNCASE.
17399 * regex.c (CHARSET_LOOKUP_RANGE_TABLE_RAW, POP_FAILURE_REG_OR_COUNT):
17400 Rename locals to avoid shadowing.
17401 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
17402 (regex_compile, re_search_2, re_match_2_internal):
17403 Remove unused local vars.

17405 which gcc can warn about.
17406 (regex_compile, re_match_2_internal): Mark locals as initialized.
17407 (RETALLOC_IF): Define only if needed.
17408 (WORDCHAR_P): Likewise. This one is never needed, but is used
17409 only in a comment talking about a compiler bug, so put inside
17410 the #if 0 of that comment.
17411 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
17412 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
17415 * search.c (boyer_moore): Rename locals to avoid shadowing.
17416 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):

17438 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
17439 New macros, so that the caller can use some names other than
17440 gcpro1, gcpro2, etc.
17441 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
17443 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
17444 argument, for consistency with GCPRO2_VAR, etc: it is now the
17445 prefix of the variable, not the variable itself. All uses
17447 * dired.c (directory_files_internal, file_name_completion):
17448 Rename locals to avoid shadowing.
17450 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
17451 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
17452 dired.c's scmp function, had undefined behavior.
17453 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
17454 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
17455 * buffer.h: ... to here, because these macros use current_buffer,
17456 and the new implementation with inline functions needs to have
17457 current_buffer in scope now, rather than later when the macros
17459 (downcase, upcase1): New static inline functions.
17460 (DOWNCASE, UPCASE1): Reimplement using these functions.
17461 This avoids undefined behavior in expressions like
17462 DOWNCASE (x) == DOWNCASE (y), which previously suffered
17463 from race conditions in accessing the global variables
17464 case_temp1 and case_temp2.
17465 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
17466 * lisp.h (case_temp1, case_temp2): Remove their decls.
17467 * character.h (ASCII_CHAR_P): Move from here ...
17468 * lisp.h: ... to here, so that the inline functions mentioned
17469 above can use them.
17471 * dired.c (directory_files_internal_unwind): Now static.
17473 * fileio.c (file_name_as_directory, directory_file_name):
17474 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
17476 (file_name_as_directory): Use const pointers when appropriate.
17477 (Fexpand_file_name): Likewise. In particular, newdir might
17478 point at constant storage, so make it a const pointer.
17479 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
17480 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
17482 (Fset_file_times, Finsert_file_contents, auto_save_error):

17487 to avoid shadowing.
17489 * marker.c (bytepos_to_charpos): Remove; unused.
17491 * lisp.h (verify_bytepos, count_markers): New decls,
17492 so that gcc does not warn that these functions aren't declared.
17494 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
17495 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
17496 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
17497 (copy_text): Remove unused local var.
17499 * filelock.c (within_one_second): Now static.
17500 (lock_file_1): Rename local to avoid shadowing.
17502 * buffer.c (fix_overlays_before): Mark locals as initialized.
17503 (fix_start_end_in_overlays): Likewise. This function should be
17504 simplified by using pointers-to-pointers, but that's a different
17506 (switch_to_buffer_1): Now static.
17507 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
17508 (report_overlay_modification): Rename locals to avoid shadowing.
17510 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
17511 Fix pointer signedness issue.
17512 (sys_subshell): Mark local as volatile if checking for lint,
17513 to suppress a gcc -Wclobbered warning that does not seem to be right.
17514 (MAXPATHLEN): Define only if needed.
17516 * process.c (serial_open, serial_configure): Move decls from here ...
17517 * systty.h: ... to here, so that they can be checked.
17519 * fns.c (get_random, seed_random): Move extern decls from here ...
17520 * lisp.h: ... to here, so that they can be checked.
17522 * sysdep.c (reset_io): Now static.
17523 (wait_for_termination_signal): Remove; unused.
17525 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):

17528 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
17529 (DENSE_TABLE_SIZE): Remove; unused.
17530 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
17531 (describe_map_tree):
17532 Rename locals to avoid shadowing.
17534 * keyboard.c: Declare functions static if they are not used elsewhere.

17683 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
